But anastomotic leakage is one of the most serious complications following laparoscopic low anterior resection (LAR) for rectal cancer. The purpose of this study was to investigate whether transanal drainage tube placement can reduce anastomotic leakage and avoid re-operation after laparoscopic LAR. Methods: Retrospective assessment was performed on 143 patients with rectal cancers who underwent laparoscopic LAR between April 2009 and March 2016. A diverting stoma was not created in all 143 patients. A transanal drainage tube was placed after anastomosis using a double stapling technique, in 90 patients (group TT). In group TT, a 24 Fr. Silicon catheter was inserted into the anus and was placed approximately 20 - 25 cm in the descending colon. Another 53 patients were operated on without a transanal drainage tube (group NTT). Clinicopathological and operative variables, the frequencies of anastomotic leakage and re-operation after leakage were investigated. Results: Between the two groups (Group TT and NTT), age, gender, body mass index, tumor size, Dukes’ stage, the number of Liniar stapler firings for rectal transaction, and the rate of left colic artery preservation were comparable. Intra-operative blood loss and operation time decreased group TT from group NTT (p < 0.05). The frequency of leakage was 2.8% (2/69) in group TT and was 13.2% (7/53) in group NTT. The rate of leakage was significantly lower in group TT (p = 0.03). Furthermore, the re-operation rate for symptomatic anastomotic leakage was 0% (0/2) in group TT, while in contrast it was 28.5% (2/7) in group NTT. The rate of re-operation was lower in group TT than group NTT (p = 0.07) and all cases with symptomatic leakage in group TT were cured by conservative treatment. There was no side effect of transanal drainage tube (perforation or bleeding of the colon, or deviation of the tube) in Group TT. Conclusions: Transanal drainage tube placement prevents anastom展开更多

Methods Seventy-three patients with MLBO from the clinical unit underwent SEMS (n = 51) or TDT (n = 22) placement from 2012 to 2017. The success rates of placement, clinical outcomes after decompression, complications, the time to resuming enteral nutrition (EN), Karnofsky performance status (KPS) scoring and the following-up therapeutic options were investigated. Results Technical success were achieved in 100% of patients in both groups. The clinical success rates were 98.0%(50/51) for SEMS and 95.5%(21/22) for TDT. No perforation was found in any group, while 3.9%(2/51) in the SEMS and 18.2%(4/22) in TDT group experienced displacement (P = 0.26). It took 2.1 IQR (0~2) days and 3 IQR (2~5) days to resume EN in the SEMS and TDT groups, respectively (P < 0.001). The KPS scores were significantly higher in patients implanted with SEMS (70, IQR 50~80) than in those with TDT (35, IQR 30~50)(P < 0.001). In the SEMS group, 37.3%(19/51) of patients underwent stenting as a bridge to surgery, 9.8%(5/51) for chemotherapy only and 52.9%(27/51) for palliation, while 40.9%(9/22), 0 and 59.1%(13/22) underwent placement for these reasons in the TDT group, respectively. The majority (6/9) of the patients who underwent TDT placement as a bridge to surgery required stoma creation, while only 31.6%(6/19) of those in the SEMS group needed a stoma (P = 0.080). In addition, anastomotic leakage was only found in the TDT group (2/9)(P = 0.10). Conclusion Both SEMS and TDT placement could provide clinical relief for MLBO. However, SEMS placement is associated with earlier EN, fewer complications, and benefits for the postoperative quality-of-life.展开更多
