    Abstract:
    OBJECTIVE: To summarize the perioperative and postoperative complications follow laparoscopic intersphincteric resection (LapISR) in the treatment of low rectal cancer and their management. METHODS: An observational study was conducted in 73 consecutive patients who underwent LapISR for low rectal cancer between June 2011 and February 2016 in our hospital. The clinicopathological parameters, perioperative and postoperative complications, and clinical outcomes were collected from a prospectively maintained database. Perioperative and postoperative complications were defined as any complication occurring within or more than 3 months after the primary operation, respectively. RESULTS: Forty-nine(67.1%) cases were male and 24(32.9%) were female with a median age of 61(25 to 79) years. The median distance from distal tumor margin to anal verge was 4.0(1.0 to 5.5) cm. The median operative time was 195 (120 to 360) min, median intra operative blood loss was 100 (20 to 300) ml, median number of harvested lymph nodes was 14(3 to 31) per case. All the patients underwent preventive terminal ileum loop stoma. No conversion or hospital mortality was presented. The R0 resection rate was 98.6% with totally negative distal resection margin. A total of 34 complication episodes were recorded in 21(28.8%) patients during perioperative period, and among which 20.6%(7/34) was grade III(-IIII( according to Dindo system. Anastomosis-associated morbidity (16.4%,12/73) was the most common after LapISR, including mucosa ischemia in 9 cases(12.3%), stricture in 7 cases (9.6%, 4 cases secondary to mucosa necrosis receiving anal dilation), grade A fistula in 3 cases (4.1%) receiving conservative treatment and necrosis in 1 case (1.4%) receiving permanent stoma. After a median follow up of 21(3 to 60) months, postoperative complications were recorded in 12 patients (16.4%) with 16 episodes, including anastomotic stenosis (8.2%), rectum segmental stricture (5.5%), ileus (2.7%), partial anastomotic dehiscence (1.4%), anastomotic fistula (1.4%), rectovaginal fistula (1.4%) and mucosal prolapse (1.4%). These patients received corresponding treatments, such as endoscopic transanal resection, anal dilation, enema, purgative, permanent stoma, etc. according to the lesions. Six patients (8.2%) required re-operation intervention due to postoperative complications. CONCLUSION: Anastomosis-associated morbidity is the most common after LapISR in the treatment of low rectal cancer in perioperative and postoperative periods, which must be strictly managed with suitable methods.
