To study the comparison between the primary closure and open technique after excision of chronic sacrococcygeal pilonidal sinus.
                A randomized study was designed and 77 patients with chronic sacrococcygeal pilonidal sinus were included in this study. This study took place in Rizgary Teaching Hospital, Erbil, Kurdistan, Iraq, from January 1997 to August 2003. The patients were separated into 2 groups; Group A (37 patients) were treated by open method (excision and healing by secondary intention) and Group B (40 patients) for whom primary midline suturing was performed after excision of the pilonidal sinus. The follow up ranged from 1.5-5.5 years (mean 4.16) was through outpatient visits.
                The Student t test was applied for statistical analysis for the operating time, hospital-stay, time off from work and wound healing time; and the results show extremely significant differences between the 2 groups (p < 0.0001). The statistical analysis of the total number of postoperative complications of both techniques showed a significant difference (p = 0.0401), while the differences were insignificant for each complication when analyzed separately.
                Excision and primary closure for chronic sacrococcygeal pilonidal sinus is superior to excision and healing by secondary intention. We believe that primary midline suturing is a useful method for management of chronic sacrococcygeal pilonidal sinus. This study describes a prospective randomized controlled trial to evaluate whether suture of the peritoneal layer is necessary as a separate step in the closure of midline abdominal surgical wounds. Consecutive patients undergoing abdominal operation--elective and emergency surgery--through a midline abdominal wound were randomized to have the peritoneal layer closed with continuous catgut, or to have this step omitted. The linea alba was closed with interrupted stainless steel sutures, and the skin approximated with staples. Patients were evaluated for wound sepsis, wound dehiscence, and subsequent incisional hernia development. Postoperative pain was assessed by a self-administered visual analogue score, and by measuring narcotic requirements. There was no significant difference in narcotic requirements, pain scores, or wound complications between the 2 groups. Single-layer closure of the abdominal wall is quicker, less costly, and theoretically safer than layered closure, and it is recommended that separate suture of the peritoneum be abandoned. Hair entry into the midline is the generally accepted theory in pilonidal sinus formation. This theory is also involved in the pathogenesis of the recurrence after different types of operations for pilonidal sinus disease. The relationship of the suture lines and the midline was evaluated in this study.
                Thirty-four patients with stage 4 or recurrent pilonidal sinus disease who underwent V--Y advancement flap closure were randomized into two groups: vertical suture line unrelated to midline (VLUM, n=18) and vertical suture line related to midline (VLRM, n=16).
                None of the patients with or without a suction drain developed flap necrosis, local haematomas or seromas. The median length of the postoperative hospital stay was 3 days for theVLRM group and the VLUM group (p>0.05). The median follow-up period was 32 months. During the follow-up period, two recurrences were determined 22 and 15 months after operation in the VLRM group. Recurrences were situated in the scar tissue over the midline.
                Routine application of suction drains is not recommended after V--Y advancement flap closure. Avoidance of the relationship of the postoperative suture line and the midline, if possible, offers a safe method of definitive reconstruction. To evaluate the outcome of excision with or without primary closure in the management of chronic pilonidal sinus (PNS) disease.
                Between July 2002 and November 2006, a randomized trial was conducted in the Department of General Surgery, Riyadh Medical Complex, Riyadh, Kingdom of Saudi Arabia. All the patients who presented with chronic natal cleft PNS disease were included in the study. They underwent either excision with midline closure (EMC group), or excision without closure (EWC group). Patients, who came with an acute pilonidal abscess (complicated) were excluded from the study. The principle outcome measures recorded were wound infection, healing time, time off work and the recurrence rate.
                A total of 380 patients of chronic PNS were divided into EMC group, (188 patients) and EWC group (192 patients). Majority of the patients were male in both the groups (93%). The hospital stay ranged from 2 to 5 days (mean = 3.6 +/- 1.4 days) for EMC group, while it was 3-5 days (mean = 4 +/- 1.1 days) for EWC group (p < 0.002). wound infection was 4.2% in EMC group, compared to 3.12% of EWC group (MS). The mean healing time and time off work in EMC group was significantly shorter than the patients in EWC group. Median follow up of EMC group was 36.3 months (range 10-52 months) while it was 35.2 months (range 13-51 months) for EWC group. Statistically there was no significant difference in the recurrence rate of both the groups (3.7% vs. 3%).
                Excision and primary closure is recommended, as a preferred procedure in the management of chronic PNS disease. It has the advantages of early wound healing, rapid return to work and comparable recurrence rate with excision and open wound. Postoperative abdominal adhesions are associated with significant morbidity and mortality, placing a substantial burden on healthcare systems worldwide. Development of a bioresorbable membrane containing up to 23 percent glycerol and chemically modified sodium hyaluronate/carboxymethylcellulose offers ease of handling and has been shown to provide significant postoperative adhesion prevention in animals. This study was designed to assess the safety of glycerol hyaluronate/carboxymethylcellulose and to evaluate its efficacy in reducing the incidence, extent, and severity of postoperative adhesion development in surgical patients.
                Twelve centers enrolled 120 patients with ulcerative colitis or familial polyposis who were scheduled for a restorative proctocolectomy and ileal pouch-anal anastomosis with diverting loop ileostomy. Before surgical closure, patients were randomized to no anti-adhesion treatment (control) or treatment with glycerol hyaluronate/carboxymethylcellulose membrane under the midline incision. At ileostomy closure, laparoscopy was used to evaluate the incidence, extent, and severity of adhesion formation to the midline incision.
                Data were analyzed using the intent-to-treat population. Treatment with glycerol hyaluronate/carboxymethylcellulose resulted in 19 of 58 patients (33 percent) with no adhesions compared with 6 of 60 adhesion-free patients (10 percent) in the no treatment control group (P = 0.002). The mean extent of postoperative adhesions to the midline incision was significantly lower among patients treated with glycerol hyaluronate/carboxymethylcellulose compared with patients in the control group (P < 0.001). The severity of postoperative adhesions to the midline incision was significantly less with glycerol hyaluronate/carboxymethylcellulose than with control (P < 0.001). Adverse events were similar between treatment and no treatment control groups with the exception of abscess and incisional wound complications were more frequently observed with glycerol hyaluronate/carboxymethylcellulose.
                Glycerol hyaluronate/carboxymethylcellulose was shown to effectively reduce adhesions to the midline incision and adhesions between the omentum and small bowel after abdominal surgery. Safety profiles for the treatment and no treatment control groups were similar with the exception of more infection complications associated with glycerol hyaluronate/carboxymethylcellulose use. Animal models did not predict these complications. To determine whether a transverse incision is an alternative to a midline incision in terms of incisional hernia incidence, surgical site infection, postoperative pain, hospital stay and cosmetics in cholecystectomy. Incisional hernias after midline incision are commonly underestimated but probably complicate between 2 and 20% of all abdominal wall closures. The midline incision is the preferred incision for surgery of the upper abdomen despite evidence that alternatives, such as the lateral paramedian and transverse incision, exist and might reduce the rate of incisional hernia. A RCT was preformed in the pre-laparoscopic cholecystectomy era the data of which were never published.
                One hundred and fifty female patients were randomly allocated to cholecystectomy through midline or transverse incision. Early complications, the duration to discharge and the in-hospital use of analgesics was noted. Patients returned to the surgical outpatient clinic for evaluation of the cosmetic results of the scar and to evaluate possible complications such as fistula, wound dehiscence and incisional hernia after a minimum of 12 months follow-up.
                Two percent (1/60) of patients that had undergone the procedure through a transverse incision presented with an incisional hernia as opposed to 14% (9/63) of patients from the midline incision group (P = 0.017). Transverse incisions were found to be significantly shorter than midline incisions and associated with more pleasing appearance. More patients having undergone a midline incision, reported pain on day one, two and three postoperatively than patients from the transverse group. The use of analgesics did not differ between the two groups.
                In light of our results a transverse incision should, if possible, be considered as the preferred incision in acute and elective surgery of the upper abdomen when laparoscopic surgery is not an option. The best surgical technique for treating pilonidal sinus disease is controversial. The aim of this study is to compare the modified lay-open technique with primary closure following excision with respect to operating time, healing time, time before return to work, morbidity rate, and recurrence rate.
                After a pre-study power analysis, 142 patients with chronic sacrococcygeal pilonidal sinus were prospectively and randomly allocated, either to the modified lay-open group (Group A, n=73) or the primary closure group (Group B, n=69). In the former, incision, curettage, partial lateral wall excision, and marsupialization were performed. Single doses of cefazoline (1 g) and metronidazole (500 mg) were given intravenously 15 min before surgery to all patients.
                There were no differences with respect to gender, age, body mass index, and mean operating time between the groups. In Group A, healing failure and early bridging occurred in one patient each. In Group B, wound infection occurred in four patients, wound breakdown in three, one healing failure and hematoma in one patient each. Morbidity and recurrence rates were significantly lower in Group A (2.7 vs. 13%, P=0.028 and 1.4 vs. 17.4%, P<0.001 respectively). The median time before return to work in Group A was significantly shorter than in Group B (3 [range 2--8] vs. 21 [range 14--63] days, P<0.001). The median healing time in Group A was significantly longer than in Group B (7 [range 3--16] weeks vs. 2 [range 2--9] weeks; P<0.001).
                The results of the present study suggest that modified lay-open is superior to excision with primary closure for the surgical treatment of chronic sacrococcygeal pilonidal sinus with regard to morbidity and recurrence rates, and time before return to work, although healing time is longer. Vacuum-assisted closure has become a new technique in the challenging management of contaminated, acute, and chronic wounds. Although promising clinical results have been described, scientific proof to substantiate the mechanism of action of this therapy is scarce. In the present study, we examined whether the positive effect on wound healing found in vacuum-assisted closure-treated wounds could be explained by an effect on the bacterial load. Fifty-four patients who needed open wound management before surgical closure were included in this study. Wounds were randomized to either vacuum-assisted closure therapy (n= 29) or treatment by conventional moist gauze therapy (n= 25). Healing was characterized by development of a clean granulating wound bed ("ready for surgical therapy") and reduction of wound surface area. To quantify bacterial load, biopsies were collected. No significant difference was found in time needed to reach "ready for surgical therapy" comparing both therapies. Wound surface area reduction was significantly larger in vacuum-assisted closure-treated wounds: 3.8 +/- 0.5 percent/day (mean +/- SEM) compared to conventional-treated wounds (1.7 +/- 0.6 percent/day; p < 0.05). The total quantitative bacterial load was generally stable in both therapies. However, nonfermentative gram negative bacilli showed a significant decrease in vacuum-assisted closure-treated wounds (p < 0.05), whereas Staphylococcus aureus showed a significant increase in vacuum-assisted closure-treated wounds (p < 0.05). In conclusion, this study shows a positive effect of vacuum-assisted closure therapy on wound healing, expressed as a significant reduction of wound surface area. However, this could not be explained by a significant quantitative reduction of the bacterial load. The aim of this study was to determine which of Bascom's simple techniques, Bascom's simple surgery or Bascom's cleft closure, is preferred in the management of moderate-severity pilonidal disease.
                Fifty-five patients with chronic pilonidal disease were randomized to receive Bascom's simple surgery (n = 29) or cleft closure (n = 26) under local anesthetic. The primary end point was time to healing. Patients were followed up for a median of 3 years (range, .7-4 y).
                After Bascom's simple surgery, 5 of 29 patients did not heal and proceeded to cleft closure. The remaining patients healed at a median of 4 weeks (range, 3-35 wk). After cleft closure, 21 of 26 wounds healed primarily on removal of sutures at 10 to 13 days. The remaining 5 wounds healed at a median of 4.5 weeks (range, 2-5 wk). Fifty of 55 (91%) patients were contacted for follow-up evaluation, disease recurrence occurred in 2 of 24 after Bascom's simple surgery and in 0 of 26 after cleft closure.
                Cleft closure offers more predictable healing than Bascom's simple surgery, with less need for re-operation. Disease recurrence is more prevalent after Bascom's simple surgery. After excision of the pilonidal sinus, some surgeons leave the wound open, and others close the wound primarily. The aim of this study is to compare length of hospital stay, length of time to return to work, wound infection rate, and recurrence rate in chronic pilonidal sinus patients, after modification of both closed and open techniques.
                One hundred ten patients who had chronic-stage pilonidal sinus were randomly assigned to receive one of two excisional surgical procedures. One-half were treated by surgical excision and primary closure (closed technique, Group A). The other one-half were treated with Obeid's surgical excision (open technique, Group B).
                Ninety-one (46 in Group A and 45 in Group B) of 110 patients were followed for a period four months to three years. Although patients with primary closure had significantly longer hospital stays (P < 0.05) than patients in the open group, they returned to work significantly earlier (P < 0.05). In Group A and Group B, infection rates were 3.6 percent and 1.8 percent (P > 0.01), and recurrence rates were 4.4 percent and 0 percent (P > 0.01), respectively.
                Because both techniques have very low complication rates, treatment of chronic pilonidal sinus should be based on patient preference and characteristics, especially employment status. To assess two techniques of primary closure after excision of pilonidal sinus.
                Prospective randomised study.
                University department of surgery, United Arab Emirates.
                46 patients with chronic pilonidal sinus disease, 24 treated by rhomboid flap transposition, and 22 by deep suturing technique.
                Early mobility and recurrence.
                All patients in the rhomboid flap transposition group healed their wounds primarily compared with 17 in the primary deep suturing group (77%). (P = 0.02). Five patients wounds broke down as a result of haematoma and infection (23%). The mean hospital stay for the rhomboid flap technique was 6 days compared with 9 days after deep suturing, and the mean follow up for both groups was 18 months, the rhomboid flap group returned to work a mean of nine days earlier than the deep suturing group (23 days). No recurrence has been identified yet in the rhomboid flap group, while 2 recurrences have developed in the deep suturing group (9%).
                Primary closure after excision of pilonidal sinus with a transposed rhomboid flap is successful in the management of pilonidal sinus and is superior to primary closure by deep suturing. A prospective, randomised study was conducted to compare the wound closure performance and cosmetic outcome of caesarean section wounds closed with traditional Prolene suture or a new wound closure device (Leukosan(®) SkinLink). Sixty-one patients referred to primary section were allocated to wound closure with either Leukosan(®) SkinLink or Prolene suture. Cosmetic outcome as the primary measure was evaluated by the patient, the surgeon as well as by independent examiners blinded to the method of wound closure. Evaluations were recorded at 3, 6 and 12 months following wound closure. Both methods of wound closure scored equally high on the visual analogue scale for cosmetic evaluation at the 3-, 6- and 12-month follow-ups as assessed by the patient, surgeon and the blinded observers. The study has shown that innovative methods for wound closure compared with traditional methods such as suture providing excellent cosmetic results represent a valid alternative to physician and patient for surgical incisions.

Two methods for treatment of chronic pilonidal disease were compared in a randomised trial of 100 patients with a mean follow-up of 29 months. Four patients were excluded from the excision and closure group, leaving 96 patients for analysis. Initial primary healing was significantly more frequent after excision and primary closure (45/46; 98%) compared with excision and healing by secondary granulation (36/50; 72%). The mean healing time was significantly shorter in the excision and closure group (10.3 days) compared to the excision and granulation group (13 weeks). There was, however, no significant difference between the two groups in cure rate after the first operation. The recurrence rate in the excision and granulation group was 12% and after primary closure 20%. The presence of stiff hair and anaerobic bacteria were related to the failure of primary healing, but not associated with recurrence. Although the cure rate was the same regardless which operation was done, the primary healing was quicker and the healing time and duration of sick-leave were shorter after primary closure. Excision with primary closure therefore seems to be the preferable method. To compare the surgical efficacy and wound-healing characteristics of the tissue adhesive octyl-2-cyanoacrylate (approved by the Food and Drug Administration) with traditional suture closure in upper blepharoplasty.
                Prospective, randomized, blinded study comparing cosmetic and functional outcome and time efficiency. Twenty subjects underwent upper eyelid blepharoplasty. Each patient had a control side and an experimental side determined randomly. One eyelid incision was closed with octyl-2-cyanoacrylate (Dermabond; Ethicon Inc, Somerville, NJ) tissue glue, and the other with 6.0 suture (polypropylene or fast-absorbing gut). Comparisons were performed for the time for closure by each method, wound healing, and patient satisfaction. Macrophotographs of the wounds at 1, 2, and 4 weeks after surgery were graded by 5 observers blinded to the closure method, using a 10-point scale and a modified Hollander wound evaluation scale.
                No statistically significant difference was found between the quality of octyl-2-cyanoacrylate closure and suture closure at 1 month. There were no differences in wound complications, duration of healing, inflammation, or final incision appearance. By 2 weeks, the sides were indistinguishable in 15 (75%) of the patients. Time for closure averaged 7 minutes with suture and 8 minutes with glue.
                Octyl-2-cyanoacrylate glue is an excellent alternative to suture closure, producing equivalent quality of closure at all time points and no difference in appearance. This adhesive was sufficient to withstand the forces of closure in upper eyelid blepharoplasty without dehiscence in the absence of sutures. To evaluate the outcome of each of the three methods used to treat pilonidal sinus disease.
                A prospective blind randomised study.
                Between April 2000 and February 2003, 83 patients (68 male and 15 female), aged between 19 and 31 years (mean 26.6), scheduled for elective operations for pilonidal sinus disease. Patients were randomly assigned to receive one of three excisional surgical procedures. Group A consisted of 28 patients (22 males and six females) and underwent wide resection of the skin and subcutaneous tissue of the natal cleft, followed by primary closure of the wound in two layers after insertion of suction drain. Group B consisted of 26 patients (22 males and four females) and underwent wide resection of the skin and subcutaneous tissue and their wounds left opened for secondary intention healing. Group C consisted of 29 patients (24 males and five females) and underwent limited excision of the fistulous tract and their wounds were left opened for secondary intention healing. Patients were followed-up for 15 to 48 months post-operatively. Demographic data, operative time, hospital stay, operative blood loss, post-operative pain, wound healing time and patient's satisfaction were recorded.
                The limited excision group of patients had a highly significant shorter operative time than the closed wound group of patients (p<0.001). They also had the shortest hospital stay, operative blood loss and post-operative pain (p<0.001). The closed wound group of patients showed significantly shortest wound healing time, followed by the limited excision group of patients; the wide excision group of patients showed the longest healing time. Apart from the minimal non-significant elevation of the rate of recurrence in the closed wound group of patients, there was no difference between the three groups. All recurrent cases were obese patients and presented within the first six months after operations.
                Limited excision of a pilonidal sinus represents one of the best therapeutic options. The result of this method is comparable with the more aggressive frequently used excisional method, and it has the advantage of having a shorter convalescence and better patient satisfaction. Topical 2-octylcyanoacrylate tissue adhesive is an alternative to traditional devices for closing short surgical incisions.
                An open-label, randomized study compared a new high-viscosity formulation of 2-octylcyanoacrylate with commercially available devices, including low-viscosity 2-octylcyanoacrylate, for epidermal closure of incisions > or = 4 cm requiring subcutaneous and/or deep-dermal suturing.
                Of patients with 1 to 3 wounds, 106 were treated with high-viscosity 2-octylcyanoacrylate and 103 with commercially available devices. The day-10 rates of healing by wound were 96% and 97% for study versus control treatment and 97% and 95% for new and old 2-octylcyanoacrylate formulations versus other controls, respectively. Day-10 infection rates by wound were 4 of 145 versus 7 of 131 for study versus control treatment and 6 of 207 and 5 of 69 for new and old 2-octylcyanoacrylate versus other controls, respectively.
                The new tissue adhesive formulation provides epidermal wound closure equivalent to commercially available devices with a trend to decreased incidence of wound infection.
                Copyright 2004 Excerpta Medica, Inc. Cases treated surgically using wide excision plus classic Limberg flap or wide excision plus asymmetric modified Limberg flap were compared with respect to complications and patient comfort in the postoperative period.
                In this prospective, randomized study, 68 of 70 patients were followed for a mean of 29.22 (range, 6-44) months after wide excision plus classic Limberg flap (Group 1, n=35) and after asymmetric modified Limberg flap closure (Group 2, n=33).
                There were significantly more macerations in Group 1 (P<0.001). All macerations were detected on the lower part of the incision left on the intergluteal sulcus, and infections occurred subsequent to maceration. The infection rate was statistically higher in Group 1 than in Group 2 (P=0.028). We noted that as a result of these complications, time to suture removal (P=0.001), discharge from hospital (P=0.001), and time off from work (P=0.001) were significantly longer for Group 1 than for Group 2. There were two recurrences in the inferior part of the suture line in Group 1 and none in Group 2, which showed no statistical difference (P=0.493).
                The deep intergluteal sulcus and midline gap were slightly flattened over the anococcygeal region. The vacuum effect was decreased, and there were less macerations and fewer infections. Time off from work and discharge time from hospital were shortened by eliminating the moisture effect and reducing complications by lateralizing the lower part of the suture line. The value of peritoneal closure at the time of cesarean birth was evaluated prospectively. Two hundred forty-eight women undergoing low transverse cesarean through a Pfannenstiel skin incision were assigned to one of two groups: peritoneum open (N = 127) or peritoneum closed (N = 121). The mean (+/- SEM) surgical time in the open group (48.1 +/- 1.2 minutes) was significantly less than for the closed group (53.2 +/- 1.4 minutes) (P less than .005). There were no postoperative differences between the groups in the incidence of wound infection, dehiscence, endometritis, ileus, and length of hospital stay. Our study suggests that leaving the parietal peritoneum unsutured is an acceptable way to manage patients at cesarean delivery. Diabetic foot wounds present a great challenge to wound care practitioners. The objective of this pilot study was to determine whether vacuum-assisted closure (V.A.C.) therapy would afford quicker wound resolution as compared to saline-moistened gauze in the treatment of postoperative diabetic foot wounds. Ten patients were randomized into either the experimental V.A.C. group or control saline gauze group. Included in the study were diabetic patients 18 to 75 years of age who had a nonhealing foot ulceration. Excluded were those patients with venous disease, coagulopathy, or those who had active infections not resolved by initial surgical debridement. All foot ulcers were surgically debrided prior to initiation of V.A.C. or gauze treatment. In the experimental group, V.A.C. dressings were applied in accordance with manufacturer's protocol for chronic wounds and changed every 48 hours. In the control group, saline gauze dressings were applied at the time of surgical debridement and changed twice a day thereafter. Measurements and photos were obtained to document wound progress. Main outcome measures included: 1) time to satisfactory healing (calculated from date of initial debridement to date of definitive closure, and 2) change in wound surface area (calculated from initial wound tracing to final tracing). Satisfactory healing in the V.A.C. group was achieved in 22.8 (+/- 17.4) days, compared to 42.8 (+/- 32.5) days in the control group. Surface area changes of 28.4% (+/- 24.3) average decrease in wound size in the V.A.C. group, compared to a 9.5% (+/- 16.9) average increase in the control group during measurement period. The use of tissue adhesives has been widely studied since the 1960s. Since then they have found use in specialties like plastic surgery, neurosurgery, ENT surgery and dental surgery. Several papers have reported their safe use, both clinically and experimentally, particularly of the newer homologue n-butyl/2-cyanoacrylate (Histoacryl). In this study 43 patients (46 wounds) whose operations involved a groin incision were randomised into two groups for skin closure either with Dexon subcuticular suture (23 wounds) or Histoacryl glue (23 wounds). We found that both sets of wounds healed well with no wound infections or excessive inflammation when assessed at one week and four weeks. However the glued wounds had consistently better cosmesis scores (mean score 4.71 at four weeks) compared to the subcuticular Dexon wounds (mean score 4.00 at four weeks) and P value of less than 0.05. We feel that there is a place for tissue adhesives in skin closure for some general surgical wounds. Cosmetic outcome of the columellar incision closure in external rhinoplasty patients has been a subject of discussion. This study was conducted to assess whether tissue adhesives provide an alternative option for sutureless closure of columellar skin incisions for cases utilizing open technique rhinoplastic surgery. One hundred and one patients undergoing external rhinoplasty were randomized to either topical application of butylcyanoacrylate or polypropylene sutures for columellar skin closure. The majority of tension on the wound edges was taken up using 5-0 chromic catgut. Cosmetic outcomes were evaluated by two otolaryngologists independently using visual analogue and Hollander wound evaluation scales in a blinded manner. There was no statistically significant difference in cosmesis between the surgeons' evaluation scores for either type or repair of the columellar incision. Since the tissue adhesive forms its own protective barrier, post-operative care is simplified. Closure with adhesives eliminates the need for post-operative suture removal requiring an extra visit that should lead to more efficient use of physician and patient time. Butylcyanoacrylate performs cosmetically as well as standard suture closure of columellar skin incision used for external rhinoplasty.
No clear benefit was shown for open healing over surgical closure. A clear benefit was shown in favour of off-midline rather than midline wound closure. When closure of pilonidal sinuses is the desired surgical option, off-midline closure should be the standard management.
