The main controversy of colon-rectal laparoscopic surgery comes from its use as a cancer treatment. Two points deserve special attention: the incidence of port-site tumor implantation and the possibility of performing radical cancer surgery, such as total mesorectum excision. Once these points are addressed, the laparoscopic approach will be used routinely to treat rectal cancer. To clarify these points, 32 patients with cancer of the lower rectum participated in a special protocol that included preoperative radiotherapy and laparoscopic total mesorectum excision. All data were recorded. At the same time, all data recorded from the experience of a multicenter laparoscopic group (Brazilian Colorectal Laparoscopic Surgeons - 130 patients with tumor of the lower rectum) were analyzed and compared with the data provided by our patients. Analysis of the results suggests that a laparoscopic approach allows the same effective resection as that of conventional surgery and that preoperative irradiation does not influence the incidence of intraoperative complications. The extent of lymph nodal excision is similar to that obtained with open surgery, with an average of 12.3 lymph nodes dissected per specimen. The rate of local recurrence was 3.12%. No port site implantation of tumor was noted in this series of patients with cancer of the lower rectum. To analyze total mesorectal excision (TME) for rectal cancer by the laparoscopic approach during a prospective nonrandomized trial.
                Improved local control and survival rates in the treatment of rectal cancer have been reported after TME.
                The authors conducted a prospective consecutive series of 100 laparoscopic TMEs for low and mid-rectal tumors. All patients had a sphincter-saving procedure. Case selection, surgical technique, and clinical and oncologic results were reviewed.
                The distal limit of rectal neoplasm was on average 6.1 (range 3-12) cm from the anal verge. The mean operative time was 250 (range 110-540) minutes. The conversion rate was 12%. Excluding the patient who stayed 104 days after a severe fistula and reoperation, the mean postoperative stay was 12.05 (range 5-53) days. The 30-day mortality was 2% and the overall postoperative morbidity was 36%, including 17 anastomotic leaks. Of 87 malignant cases, 70 (80.4%) had a minimum follow-up of 12 months, with a median follow-up of 45.7 (range 12-72) months. During this period 18.5% (13/70) died of cancer and 8.5% (6/70) are alive with metastatic disease. The port-site metastasis rate was 1.4% (1/70): a rectal cancer stage IV presented with a parietal recurrence at 17 months after surgery. The locoregional pelvic recurrence rate was 4.2% (3/70): three rectal cancers stage III at 19, 13, and 7 postoperative months.
                Laparoscopic TME is a feasible but technically demanding procedure (12% conversion rate). This series confirms the safety of the procedure, while oncologic results are at present comparable to the open published series with the limitation of a short follow-up period. Further studies and possibly randomized series will be necessary to evaluate long-term clinical outcome in cancer patients. The association of perioperative blood transfusion and cancer recurrence was analyzed in a 10-year series of 520 patients with colorectal carcinoma undergoing curative surgery. Cancer recurrence was observed in 35 of 165 (19%) non-transfused and in 119 of 355 (34%) transfused patients (p less than 0.001). A significant difference in favor of the non-transfused group was also evident in cases of colonic (p less than 0.05) and rectal (p less than 0.01) tumors separately. The transfused group had both more recurrences and higher mortality. Although there were no differences in age, sex, and Dukes's stage between the two groups, further analysis showed other significant variables explaining the different result. First, there were significantly more patients with rectal cancer in the transfused group. In addition, emergency operations for obstruction and resections of adjacent organs for tumor invasion were significantly commoner in transfused patients. Exclusion of such patients and those with small tumors excised locally per anum resulted in the disappearance of the prognostic difference between the transfused and non-transfused groups (marginally significant difference in rectal carcinoma; p = 0.05). It is concluded that the seemingly adverse effect of blood transfusion on the prognosis of colorectal carcinoma may largely be explained by other associated variables. Next to surgical margins, yield of lymph nodes, and length of bowel resected, macroscopic completeness of mesorectal excision may serve as another quality control of total mesorectal excision (TME). In this study, the macroscopic completeness of laparoscopic TME was evaluated.
                A series of 25 patients with rectal cancer were managed laparoscopically (LTME) and included in this study. The pathologic specimens of the LTME group were prospectively examined and matched with a historical group of resection specimens from patients who had undergone open TME (OTME). The two groups were matched for gender and type of resection (low anterior or abdominoperineal resection). Special care was given to the macroscopic judgment concerning the completeness of the mesorectum.
                A three-grade scoring system showed no differences between the LTME and OTME groups.
                The current study supports the hypothesis that oncologic resection using laparoscopic TME is feasible and adequate. Clinical practice guidelines in cancer are a relevant component of Catalonian Cancer Strategy aimed at promoting equity of access to therapy and quality of cancer care. The colorectal cancer (CRC) guideline was first published in 2003 and subsequently updated in 2008. This study examined the quality of therapy administered to patients with rectal cancer in public hospitals in Catalonia (Spain) in 2005 and 2007, according to CRC guideline recommendations.
                We conducted a multicentre retrospective cohort study of patients who underwent curative-intent surgery for primary rectal cancer at Catalonian public hospitals in 2005 and 2007. Data were drawn from clinical records.
                The study covered 1831 patients with rectal cancer. Performance of total mesorectal excision (TME) was poorly reported by surgeons (46.4%) and pathologists (36.2%). Pre-operative radiotherapy was performed on 52% of stage-II and -III patients. Compared to high-caseload hospitals, those with a low caseload (≤11 cases/year) registered more Hartman's procedures, worse TME quality, a higher rate of post-operative complications and lower adherence to recommended pre-operative radio-chemotherapy.
                Reporting quality of care is essential for ascertaining current performance status and opportunities for improvement. In our case, there is a need for the quality of the information included in clinical records to be improved, and variability in adherence to guideline recommendations to be reduced. In view of the fact that heterogeneity in the quality of the health care process was linked to hospital caseload, the health authorities have decided to reorganise the provision of rectal cancer care.
                Copyright © 2011 Elsevier Ltd. All rights reserved. Total mesorectal excision (TME) and colonic J pouch reconstruction has been widely practiced for mid- or low-rectal cancer. However, the laparoscopic version of TME has never been described.
                Five patients suffering from newly diagnosed mid- to low-rectal cancer were seen between March and July 1999. These five patients were selected for laparoscopic TME and colonic J pouch reconstruction because preoperative investigations revealed resectable tumor without extrarectal disease.
                There were three men and two women with a mean age of 61 years. The average body weight was 69 kg (range, 57-80). None of the patients had had previous abdominal operations. In all five patients, the tumor was located within 9 cm from anal verge. The average size of the main incision was 5 cm. All patients had a covering ileostomy at the end of the procedure. The mean operating time was 208 min; average blood loss was 158 ml; and mean hospital stay was 10.6 days. Three patients had Dukes' B disease and two had Dukes' C disease. The resection margins (proximal, circumferential, and distal) were all clear. There were no deaths or major complications. Two patients suffered from transient urinary retention. After ileostomy closure, the median frequency of bowel motion was twice per day at 6-month follow-up. Neither incontinence nor nocturnal soiling was reported.
                To the best of our knowledge, this is the first published series of such an operation. With good patient selection, laparoscopic-assisted TME and colonic J pouch-anal anastomosis is safe and feasible. There are few reports on laparoscopic rectum resection demonstrating its feasibility and efficacy in patients with rectal cancer. Most patient series are small, and results must be considered preliminary and medium-term. Our large prospective conducted study aimed to assess the effectiveness of a totally laparoscopic resection for rectum carcinoma with emphasis on perioperative and long-term oncological outcomes.
                Between November 1992 and July 2003, 194 unselected patients were resected laparoscopically for rectal carcinoma. Patients with locally advanced rectum carcinoma (uT3/uT4) and no evidence of distant metastases were candidates for neoadjuvant chemoradiation. Adjuvant treatment was administered to patients with UICC stage II/III disease. All patients were followed up prospectively to evaluate complications and late outcomes. Survival probability analysis was performed using the Kaplan-Meier method. Study selection was made by Medline search using the following key words: rectal cancer, rectal neoplasms, laparoscopy, and resection. Single case reports and abstracts were excluded. When surgical series were reported more than once, only the most recent reports were considered and listed.
                The most common procedures were low anterior resection with total mesorectum excision in 65.5% of patients and high anterior resection in 25.3%. Average operative time was 174 min. Average number of lymph nodes removed was 25.4 and length of specimen resected was 27.6 cm. Resection was curative in 145 patients and palliative in 49 cases. UICC tumor stages were as follows: stage I: 25.2%, stage II: 27.3%, stage III: 30.4%, and stage IV: 17%. Intraoperative complications were <1% for lesions of the ureter, urinary bladder, and deferent duct. Conversion to conventional surgery was necessary in two cases (1%). The most common postoperative complication was anastomotic leakage in 13.5% of patients. There was no postoperative mortality. Follow-up evaluation ranged from 1 to 128 months with a mean of 46.1 months. The most common late complication was incisional hernia in 3.6% of patients. Port-site metastases occurred in one patient (0.5%). Tumor recurrence developed in 23 of the 145 curative resected patients (11.7% distant metastases and 4.1% local recurrence). Overall local recurrence rate was 6.7% (4.1% after curative resection and 14.3% after palliative resection). Overall survival rate was 90.6% at 1 year, 74.5% at 3 years, and 66.3% at 5 years. Overall 5-year survival rate was 76.9% after curative resection and 31.8% after palliative resection. Cancer-related survival rate was 94% at 1 year, 82.4% at 3 years, and 78.9% at 5 years. At 5 years it was 87.7% after curative resection and 48.5% after palliative resection. At 5 years, the survival rate was 100% for stage I, 94.4% for stage II, 66.6% for stage III, and 44.6% for stage IV.
                Our results and the literature review clearly demonstrate that laparoscopic resection for rectal cancer is not associated with higher morbidity and mortality. Established oncological and surgical principles are respected and long-term outcomes are at least as good as those after open surgery. This study was conducted to investigate the feasibility of laparoscopic resection of rectal cancer and to compare early outcome data with the results of the conventional technique.
                From January 1996 to March 2002, 435 patients with primary rectal cancer were operated on at our institution. Low-risk, small rectal tumors treatable by local excision, rectal cancer recurrences, and emergency cases were excluded from the analysis. Three hundred thirty-four patients were operated on by the conventional open approach. One hundred one selected patients underwent surgery by the laparoscopic technique.
                Because of the selection process, significantly more patients with early tumor stages were operated on by laparoscopy. There were no differences in mean operation time, morbidity, mortality, or the anastomotic leakage rate; however, the need for intraoperative transfusion, mean stay in the intensive care unit, and length of hospital stay were reduced significantly.
                In terms of the intraoperative and early postoperative course, the laparoscopic resection of rectal cancer in a selected cohort of patients compares favorably with the open technique. Because follow-up time is limited to date, only very preliminary information can be given on tumor-related outcome data. However, these preliminary data appear to suggest that rectal cancer resection can be performed by laparoscopy in accordance with established principles of cancer therapy and that port-site metastases are not a relevant clinical problem. Prospective, randomized trials are required to determine whether the laparoscopic approach will play a significant role in the treatment of rectal cancer in the future. Recent reports suggest radiotherapy administered to the 5000-6000 cGy level can result in significant long-term survival in non-small cell carcinoma of the lung. This is particularly true for many cases that are technically operable but for medical or other reasons thoracotomy cannot be performed. Such patients drawn from Southern Appalachia where the principal industry is coal mining are the subject of this report. In this region coal miners pneumoconiosis (black lung) is common as well as other chronic respiratory disorders resulting in poor tolerance for surgery. Three hundred and eleven cases of non-small cell carcinoma were irradiated during the 4 years of 1980 through 1983. This group consisted of 77 patients with clinical Stage T1, T2, T3 all N0, M0 tumors, the majority of which were technically operable but upon whom no thoracotomy was performed because of medical reasons or patient refusal. All are available for 5-year study. Each of these patients was uniformly irradiated to 6000 cGy target dose in 30 fractions over 6 weeks using standard techniques. Absolute or crude survival in these 77 patients is as follows: 1 year, 57%; 2 year, 36%; 3 year, 21%; 4 year, 17%; and 5 year, 17%. Comparison with reported surgical series treated for cure show little difference in survival up to 2 years. Thereafter, the survival curves diverge with radiotherapy patients dying at a somewhat higher rate although by 4 years both survival curves slope similarly. A possible explanation for this difference is the advantage thoracotomy offers in early case selection allowing exclusion of advance cases from surgical reports whereas radiotherapy must include patients with occult local metastasis not identifiable on clinical grounds. This experience, among other reports include evidence that radiotherapy can result in long-term survival or cure with minimal morbidity in lung cancer patients in whom surgery carries excessive risk. Although experience of laparoscopic treatment of rectal carcinoma has been reported, there is no evidence of its oncological safety because most procedures included partial mesorectal excision or abdominoperineal excision and quality of surgery is lacking. The aim of this study was to assess the oncological results of laparoscopic total mesorectal excision with sphincter preservation for rectal carcinoma.
                From 2000 to 2003, 144 patients underwent laparoscopic total mesorectal excision with low colorectal or coloanal anastomosis for mid and low rectal adenocarcinoma. There were 88 men and 56 women, with a median age of 65 years. The tumor was located at 5.5 cm (range 1-12) from the anal verge and was classified uT1T2 in 25 cases and uT3 in 119 cases. One hundred twenty patients received preoperative radiotherapy.
                Postoperative mortality and morbidity were 1% and 34% respectively. Conversion was 14% (n = 20). Macroscopic assessment of the specimen (n = 92) showed an intact mesorectum in 88% of the cases. The distal margin and the circumferential margin were safe in 98% and 94% of the cases, respectively. A complete microscopic excision, i.e., R0 resection, was achieved in 134 cases (93%). Pathological data were similar to those of an open match group. With a median follow-up of 18 months, there was no port-site recurrence and two patients had local recurrence (1.4%). The 3-year overall and disease- free survival rates were 89% and 77%, respectively.
                A high quality of surgical excision can be achieved by the laparoscopic dissection, suggesting that this approach in treatment of rectal carcinoma is oncologically safe. The majority of patients with stage T3, N1, M0 or T1-3, N2, M0 non-small cell lung cancer are considered inoperable, and receive radical radiotherapy. This randomised trial aimed to assess whether, in this group of inoperable patients, a policy of neo-adjuvant chemotherapy (with mitomycin, ifosfamide and cisplatin (MIC) or mitomycin, vinblastine and cisplatin (MVP)) followed, if feasible, by surgery (CT-S), would result in better outcomes than radical radiotherapy (RT). The trial closed due to poor accrual, with only 48 patients randomised in 3 years. Only 4 of the 24 patients in the CT-S group had a complete resection, and of these, the 2 patients who had a pneumonectomy both died 12 days after surgery. There was no evidence of an improved survival in the CT-S group (median survival 13.8 months, compared with 11.3 months for the RT group), but because the trial failed to recruit we were unable to reach any reliable conclusions about these two treatment options.
The main source of evidence for the current practice of laparoscopic excision of renal cancer is drawn from case series, small retrospective studies and very few small randomised controlled trials. The results and conclusions of these studies must therefore be interpreted with caution.
