  • Short Term Efficacy of Total Mesorectal Resection and Intersphincter Resection for Ultra-Low Rectal Cancer and Anorectal Cancer

    Objective To investigate the safety and feasibility of the total mesorectal excision (TME) and intersphincteric resection (ISR) for ultra-low rectal cancer and anal sphincter preservation surgery for anorectal cancer, and to evaluate the short term efficacy and postoperative anal function. Methods A retrospective analysis of clinical and follow-up data of 86 cases with TME+ISR for ultra-low rectal cancer and anorectal cancer from January 2009 to December 2010 in West China Hospital of Sichuan University were performed. Results Eighty-six patients were successfully performed the operation, the lower edge of tumor from the anus was 1-5 cm (average 1.63cm); tumor diameter was 2-7 cm (average 3.4cm). The tumors were high differentiation in 4 cases, moderately differentiation in 60 cases,and poorly differentiation in 22 cases. The pTNM stages were stageⅠin 12 cases, stageⅡA in 11 cases, stage ⅡB in 15 cases, stage ⅢA in 2 cases, stage ⅢB in 23 cases, stage ⅢC in 16 cases, and stage Ⅳ in 7 cases. There were postoperative anastomotic leakage in 3 cases, perianal infection in 2 cases (1 case received reoperation with permanent colostomy because of pelvic peritoneal infection caused by perianal severe infections). Anastomotic bleeding and anastomotic stenosis were of 2 cases respectively. Rectovaginal fistula, inflammatory ileus, urinary retention, and abdominal infection were of 1 case respectively. Eighty-six patients were followed-up for 12-24 months, the mean time was 18 months. Liver metastases was found in 1 case in 7 months after operation, 2 cases dead in the 7th month and 12th month after operation respectively. Local recurrence were found in 3 cases (3.5%) in 1 year after operation. The survival rate of 1-year was 97.7% (84/86). The times of defecation was 1-5 times a day. The Kirwan’s score level on function of control defecation was 1-2 grade. Conclusions TME+ISR for low rectal cancer and anorectal cancer is a viable, safe, and radical operation type for preservation of anus. The short term efficacy is satisfactory.

  • Analysis of Risk Factors for Anterior Resection Syndrome of Rectal Cancer

    ObjectiveTo study the risk factors affecting anterior resection syndrome of rectal cancer. MethodsSixty-seven patients with low rectal cancer who performed anus preserving operation in Second Artillery General Hospital from August 2013 to October 2014 were screened out based on inclusion and exclusion criteria. Forty-two cases received low anterior resection (LAR), 25 cases received intersphincter resection (ISR). Patients were followed-up for 1 year. The severity of anterior resection syndrome was evaluated by using score system for anterior resection syndrome. The patients' age, gender, body mass index (BMI), TNM stage, surgical mode, surgical approach, anastomotic height, prophylactic colostomy, adjuvant chemotherapy, and radiotherapy were used as research indicators, and to evaluate the impact to anterior resection syndrome. ResultsThe single factor analysis showed that the surgical mode, preventive stoma, radiotherapy, anastomotic height, and age were related to the severity of anterior resection syndrome (P < 0.05). Logistic regression showed that the surgical mode (OR=4.506, 95% CI: 1.220, 16.640, P=0.024) and radiotherapy (OR=14. 688, 95% CI: 3.200, 67.429, P=0.001) were related to the severity of anterior resection syndrome. ConclusionSurgical mode and radiotherapy are the independent risk factors of anterior resection syndrome.
