Randomized study of non-closure of peritoneum in lower segment cesarean section. A randomized controlled study of peritoneal closure at cesarean section. Effectiveness of prolonged use of continuous passive motion (CPM), as an adjunct to physiotherapy, after total knee arthroplasty. Closure vs non-closure of the visceral and parietal peritoneum at cesarean delivery: 16 year study.
The advantages of non-closure of the visceral and parietal peritoneum at lower segment cesarean section seems to be evident but in the reports published so far, the number of patients studied has been relatively small and the follow-up periods short. It is obviously of value to reconfirm such important observation in several institutions and therefore, in 1991, we decided to study non-closure of the peritoneum in lower segment cesarean section in a large series of patients with long-term follow-up of at least one year.
                A prospective randomized study of 361 patients undergoing lower segment cesarean section in a University Affiliated Hospital, Al-Ain, United Arab Emirates. The operative technique was randomized to include either non-closure of both visceral and parietal peritoneum (study group, n = 179) or closure of both layers (control group, n = 182). Patients were followed up according to a study protocol. The nursing staff and the obstetricians responsible for data collection were unaware as to which of the two groups the patients belonged to. Student-t test and Chi-square test were used for statistical analysis of the results, where appropriate, with a p < 0.05 considered probability level to reflect significant differences.
                Postoperative febrile morbidity and wound infection were significantly lower in the study group as compared to the control group (p < 0.001 and p < 0.05 respectively). The incidence of wound dehiscence, urinary tract infection and the time to opening of the bowels postoperatively were similar in the two groups. In the non-closure group, the average operating time was significantly shorter by 7.9 minutes (p < 0.01) and the hospital stay was one day less (p < 0.01). There were no patients with late postoperative complications or readmissions during 2-5 years of follow-up that could be attributed to complications associated with lower segment cesarean section.
                Non-closure of the visceral and parietal peritoneum at lower segment cesarean section is associated with fewer postoperative complications, is more cost effective and is simpler than the traditional operative technique of closing both peritoneal layers. To assess the benefits or problems that may be associated with peritoneal closure at cesarean section.
                A randomized-controlled study of women undergoing cesarean section in Sultan Qaboos University Hospital Maternity Unit. After the decision is taken for cesarean section, women were randomized to either repair of peritoneum using standard technique or non-repair of peritoneum. Duration of operation, maternal morbidity, blood loss assessed by post-operative hemoglobin change and requirement of transfusion, post operative infection, thromboembolic disease, and length of hospital stay were analyzed in 2 groups of patients. Sixty women were randomized into the study, 30 group A, had peritoneal closure and 30, group B, and had non-closure.
                The average duration of operation for group A was 61.9+/-12.734, and for group B was 53.56 +/-11.209 (p< 0.01 statistically significant). There was no statistically significant difference in the length of stay, estimated blood loss, the mean drop in hemoglobin, postoperative pyrexia, and wound infection rate between the 2 groups.
                Our study has confirmed the previous study findings, and has shown that there are no advantages in suturing of the peritoneum in terms of blood loss, blood transfusion, operation duration, postoperative pyrexia and wound infection. In fact non-suturing of the peritoneum was associated with shorter operation duration (p< 0.01 significant), and reduced cost. Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty. Although research suggests that Continuous Passive Motion (CPM) should be implemented in the first rehabilitation phase after surgery, there is substantial debate about the duration of each session and the total period of CPM application. A Cochrane review on this topic concluded that short-term use of CPM leads to greater short-term range of motion. It also suggested, however, that future research should concentrate on the treatment period during which CPM should be administered.
                In a randomised controlled trial we investigated the effectiveness of prolonged CPM use in the home situation as an adjunct to standardised PT. Efficacy was assessed in terms of faster improvements in range of motion (RoM) and functional recovery, measured at the end of the active treatment period, 17 days after surgery. Sixty patients with knee osteoarthritis undergoing TKA and experiencing early postoperative flexion impairment were randomised over two treatment groups. The experimental group received CPM + PT for 17 consecutive days after surgery, whereas the usual care group received the same treatment during the in-hospital phase (i.e. about four days), followed by PT alone (usual care) in the first two weeks after hospital discharge. From 18 days to three months after surgery, both groups received standardised PT. The primary focus of rehabilitation was functional recovery (e.g. ambulation) and regaining RoM in the knee.
                Prolonged use of CPM slightly improved short-term RoM in patients with limited RoM at the time of discharge after total knee arthroplasty when added to a semi-standard PT programme. Assessment at 6 weeks and three months after surgery found no long-term effects of this intervention Neither did we detect functional benefits of the improved RoM at any of the outcome assessments.
                Although results indicate that prolonged CPM use might have a small short-term effect on RoM, routine use of prolonged CPM in patients with limited RoM at hospital discharge should be reconsidered, since neither long-term effects nor transfer to better functional performance was detected.
                ISRCTN85759656. To determine whether non-closure of visceral and parietal peritoneum at LSCS has advantages over peritoneal closure with regard to postoperative complication and adhesions.
                Prospective randomized controlled trial.
                Paholpolpayuhasena Hospital, Kanchanaburi province, Thailand
                Three hundred and sixty full-term pregnant women undergoing first cesarean section were divided into 3 groups (N = 120). Group A: non-closure of both visceral and parietal peritoneum. Group B. non-closure of only visceral peritoneum. Group C: closure of both visceral and parietal peritoneum. Postoperative complications were compared. Adhesions were evaluated in 65 patients returning for a second LSCS and compared for severity of adhesions. The three groups were compared using statistical analysis.
                There was no significant statistical difference between group A and C, group B and C for postoperative complications or number of adhesion formation. However, adhesions in the closure group were more severe.
                Closure of visceral and parietal peritoneum has no benefit over non-closure of visceral peritoneum and non-closure of both visceral and parietal peritoneum at LSCS.
There is no evidence for any short-term or long-term advantage in peritoneal closure for non-obstetric operations. If further trials are performed on this topic, they should have an adequate period of follow-up and adequate measures should be taken to ensure that the results are not subject to bias.
