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.
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.
ObjectiveTo investigate risk factors of anastomotic fistula after total mesorectum excision (TME) in middle and low rectal cancer. MethodsThe clinical data of 446 patients with middle and low rectal cancer received TME surgery from June 2004 to June 2014 were retrospectively analyzed.Single-factor analysis of risk factors was used by χ2 test,multiple-factor analysis was used by logistic regression analysis. ResultsThere were 36 patients with anastomotic fistula in these 446 patients,which of 22 patients were recovered after conservative treatment,of 14 patients were recovered after colostomy.The results of single-factor analysis showed that the age>60 years,preoperative hemoglobin<110 g/L,preoperative albumin<35 g/L,accompanied with diabetes mellitus,neoadjuvant chemoradiation,distance from anasto-mosis to anus<5 cm,non-strengthen suture by hand were the risk factors of anastomotic fistula after TME in the middle and low rectal cancer (P<0.05).The results of multiple-factor analysis showed that the preoperative hemoglobin<110 g/L,preoperative albumin<35 g/L,accompanied with diabetes mellitus,neoadjuvant chemoradiation,and distance from anastomosis to anus<5 cm were the independent risk factors of anastomotic fistula after TME in the middle and low rectal cancer (P<0.05). ConclusionsRisk of anastomotic fistula after TME in middle and low rectal cancer is higher.Basic complications of patient and local conditions of anastomosis,and intraoperative factors could affect incidence of anastomotic fistula,it should be paid enough attention.In general,most of anastomotic fistula could be cured with conservative treatment,in case of conservative treatment is invalid,colostomy is feasible.
Objective To evaluate the feasibility and clinical outcomes of laparoscopic total mesorectal excision (TME) in treating mid-low rectal cancer. Methods From March 2005 to July 2008, 74 patients with mid-low rectal cancer undergoing laparoscopic TME in Zhejiang Cancer Hospital were collected. The data of clinicopathologic parameters were analyzed. Results Laparoscopic TME was performed on 74 patients with mid-low rectal cancer. No operative death occurred in this group. No case was converted to open procedure. The mean operation time was 187 min. The mean operative blood loss was 90 ml. The mean postoperative hospital stay was 10 d. Bowel function was restored on 46 h after operation on average. The mean distance between tumor and the section edge was 3.1 cm. The average number of lymph node dissection was 19.7. The sphincter preservation rate was 97% in patients with tumor 6 cm above the anal verge. The follow-up times were 2-44 months, average 25 months. The incidence of complications was 9.5%. No tumor cell port site implantation or distant metastasis happened. One case was pelvic recurrence， no patient was dead.Conclusion Laparoscopic TME is a feasible, safe and minimally invasive technique for the patients with mid-low rectal cancer, achieving the principles of TME.
Objective To introduce the surgical technique and results of total mesorectal excision (TME) for rectal cancer. Methods Reviews.Results As a result of TME, local recurrence rates have declined from 20%-30% to 3%-8%, 5-year survival rate have risen to 75%, and the rates of sphincter preservation have risen too.Conclusion Total mesorectal excision reduces the local recurrence rates and raise the survival figures after excision of rectal cancer. Patients have a high quality of life.

ObjectiveTo evaluate the short-term clinical outcomes of transanal total mesorectal excision (TaTME) for mid-to-lower rectal cancer and provide evidence for clinical decision-making. MethodsThe relevant literature from domestic and international databases in recent years was reviewed to systematically assess the current application of TaTME in the treatment of mid-to-low rectal cancer. A comparative analysis was conducted between the TaTME and laparoscopic total mesorectal excision (LapTME), focusing on intraoperative outcomes, short-term postoperative recovery, intraoperative and postoperative complications, oncological prognosis, and the learning curve. ResultsConventional LapTME presented significant challenges in performing precise maneuvers within the pelvis and around the rectum, particularly in patients with “difficult pelvis” characteristics such as obesity, narrow pelvis, or male anatomy. In contrast, TaTME demonstrated certain advantages, including improved visualization of anatomical planes, reduced intraoperative bleeding, lower conversion rate to open surgery, faster short-term postoperative recovery, and enhanced specimen quality. ConclusionTaTME is a safe procedure with short-term outcomes, which is superior or comparable to those of laparoscopic surgery, offering a new surgical option for the treatment of mid-to-lower rectal cancer.
ObjectiveTo summarize the functional outcomes of transanal total mesorectal excision (TaTME).MethodThe literatures about functional outcomes and existing problems secondary to TaTME in China and abroad were collected to make a review.ResultsNeither the TaTME or the laparoscopic TME (LTME) had few serious impact on the quality of life of patients. At present, only a few studies were involved in the postoperative sexual function, and no definite conclusion could be drawn. From the current data only, the TaTME had few serious impact on the sexual function and it didn’t show some advantages as compared with the LTME. The urinary and defecation functions showed no obvious differences between the TaTME and the LTME, which of the patients after the TaTME might be impaired to some extent. The defecation disorders mainly occurred in 1—6 months after the TaTME, but it would recover to a certain extent as time went on.ConclusionsAlthough TaTME has more advantages in protecting pelvic autonomic nerves, there is no obvious difference in postoperative organ function as compared with LTME surgery at present. Multi-center, large sample size, and long-term follow-up studies are still needed to validate long-term results.
