ObjectiveTo evaluate the safety and short-term outcome of laparoscopic total mesorectal excision (TME) for the middle-lower rectal cancer in municipal hospital.MethodsThe pathological data of 94 patients with middle-lower rectal cancer (49 cases underwent laparoscopic TME, while 45 cases received open TME), who treated in The First People’s Hospital of Ziyang from Jan. 2015 to Jun. 2017, were retrospectively collected and analyzed.ResultsTwo patients (4.1%) in laparoscopy group were converted to open surgery. Compared with the laparotomy group, the laparoscopic group had significantly less volume of intraoperative bleeding, shorter abdominal incision, earlier time to the first flatus and liquid diet, and lower rate of 30-day postoperative complication (P<0.05), but had longer operative time (P=0.033). While there were no significant difference on postoperative stay, the specimen length, distal margin, and number of harvested lymph nodes between the 2 groups (P>0.05).ConclusionLaparoscopic TME is a feasible, safe, and minimally invasive technique for middle-lower rectal cancer, and produce more favourable short-term outcome than open surgery in municipal hospital.

ObjectiveTo investigate the progress and controversy of membrane anatomy theory in laparoscopic surgery for mid-low rectal cancer. MethodThe literature related to membrane anatomy theory in recent years was reviewed and summarized. ResultsThe membrane anatomy theory not only improved the effect of total mesorectal excision, ensured the integrity of the mesorectum, more standardized the operation and principles of rectal cancer surgery, but also provided the operator with a broad vision and clear anatomical hierarchy. The theory of membrane anatomy had important clinical significance for tumor radical resection, organ resection and functional protection. However, this theory had not been unified, and the establishment of membrane plane and the choice of surgical plane were still needed to be studied and explored. ConclusionAt present, scholars at home still regard the theory of membrane anatomy as the theoretical support and reference basis for the endoscopic treatment of mid-low rectal cancer, which can provide surgeons with new treatment prospects and research direction, and improve the survival expectancy and quality of life of patients with intestinal cancer in the future.
Objective To investigate the application of air leak test combined with methylene blue solution leak test in the detection of anastomotic leakage after total mesorectal excision （TME） in rectal cancer. Methods In total of132 patients with rectal cancer underwent Dixon according to TME in our hospital from Mar. 2010 to Mar. 2013 were enrolled. All patients were randomly divided into air leak test group （n=65） and air leak＋methylene blue solution leak test group （n=67）. The intestinal anastomosis of patients in air leak test group were clamped at 2 cm from the upper endof bowel， then injecting 500 mL distilled water to pelvic， and placing 24# Foley catheter through the anus. The catheter balloon was injected with water to close anus， and then injected with 50 mL gas to find the anastomotic leakage where bubbles happened， and then repaired it. Patients of air leak＋methylene blue solution leak test group were treated with methylene blue solution test in addition. After sucking out of the distilled water in pelvic and gas in the rectum， 1 bottle of methylene blue solution （20 mg） and 50 mL saline were injected， observing the location where the methylene blue solutionleaking out and repaired it. Results Three cases （4.62%） of anastomotic leakage were found during operation in air leak test group， and 9 cases （13.85%） were found after operation. Of the 9 cases， 5 cases were cured with placement of adeq-uate drainage and symptomatic treatment， 3 cases were cured with anal patch， and 1 case was cured with transverse colon fistula and drainage. In total of 15 cases （22.39%） were found anastomotic leakage， 2 cases of them were found by air leak test and another 13 cases were found by methylene blue solution leak test during operation in air leak＋methylene bluesolution leak test group， but no one suffered anastomotic leakage after operation. Compared with air test group， detectionrate of anastomotic leakage during operation was higher （P＜0.05）， and incidence rate of anastomotic leakage after opera-tion was lower in air leak＋methylene blue solution leak test group （P＜0.05）. Conclusions Large anastomotic leakage can be found by using air leak test， and small and hidden leakage can be found by using methylene blue solution leak test， combination method of the two experiments is better. Repair can be performed effectively under direct vision.
Objective To prospectively evaluate the health-related quality of life (HRQOL) outcomes in patients undergoing laparoscopic total mesorectal excision (LTME) with anal sphincter preservation (ASP) for low rectal cancers. Methods From June 2001 to March 2004, 125 patients undergoing LTME and 103 patients undergoing OTME were included in this study. The international standard questionnaires (QLQ-C30 and QLQ-CR38) were used to evaluate the conditions of patients at 3 periods after surgery respetively: 3-6 months, 12-18 months, gt;24 months. Results In contrast to OTME patients, the LTME ones showed significantly better physical function during 3-6 months after surgery, less micturition problems within 12-18 months, less male sexual problems and better sexual function during 12-18 months after surgery, with better sexual enjoyment after postoperative 24 months. Both groups showed significant improvement in most subscales from the first to the second assessment, and improvement in sexual enjoyment from the second to the third assessment. The sexual function, micturition problems and male sexual problems in LTME group significantly improved from the first to the second assessment, whereas the sexual function in OTME group improved from the second to the third assessment.Conclusion Patients undergoing LTME for low rectal cancers have bette postoperative HRQOL than patients undergoing OTME, with better physical function, micturition function, overall sexual and male sexual functions in short term, and better sexual enjoyment in the long term. The HRQOL of both LTME and OTME patients may be expected to improve over time, particularly in the first postoperative year.
After more than 10 years of development, transanal total mesorectal excision (taTME) has played an important role in anus-preserving surgery for low rectal cancer. Existing studies have shown that taTME is not significantly different from traditional laparoscopy in the short-term and long-term efficacy of the treatment of low rectal cancer, and that taTME has potential advantages in postoperative functional recovery. With the maturity of taTME technology, transanal endoscopic approach has gradually been clinically applied to other rectal tumors, anastomotic stenosis, lateral lymph node dissection and other scenarios. Clinical practice shows that the transanal endoscopic approach can dissect pelvic tissues more accurately, greatly reduce the difficulty of surgery for complex pelvic diseases, improve the safety of surgery, and provide new ideas for clinical practice.
Objective To study the relationship between autonomic nerve preservation and sexual and urinary functions after total mesorectal excision in patients with cancer of the lower rectum, and to explore improved nursing methods for these patients. Methods Eligible patients with cancer of the lower rectum were non-randomly assigned to either a control group (n=278)or an autonomic nerve-preserving group （n=263）. The recovery time of micturition desire, catherization time, lower urinary tract infection rate, residual urine, severity of urinary disorders and sexual disorders were observed. Results The recovery time of micturition desire, catherization time, lower urinary tract infection rate, residual urine, severity of urinary disorders and sexual disorders were lower in the autonomic nerve-preserving group than in the control group. (Plt;0.05) . Conclusion Autonomic nerve preservation radical resection leads to better maintenance of urinary and sexual functions for patients with cancer of the lower rectum. Nursing should be focused on the prevention of urinary tract complications and the rehabilitation of sexual and urinary functions.
