Abstract
BACKGROUND: Anastomotic leakage (AL) is one of the most severe early complications after rectal cancer surgery. Many studies and meta-analysis results show that the indentation of transanal drainage tubes (TDT) can prevent and reduce the incidence of AL. However, the size and material of drainage tubes are rarely reported. Herein, we compare the effect of three kinds of TDT and analyze the use of TDT material and size to prevent AL, which may better prevent the occurrence of AL. METHODS: The clinical data of 182 patients who underwent laparoscopic anterior resection of rectal cancer were retrospectively analyzed between January 2016 and March 2019. According to the types of indwelling TDT after the operation, they were divided into Fr32 silicone tubes (81 cases), Fr24 silicone tubes (54 cases), Fr24 latex tubes (47 cases). The first drainage, exhaust, defecation, abdominal distension and anastomotic leakage of the patients with three different types of TDT were compared. RESULTS: There was no significant difference in the degree of first exhaust, abdominal distension and anastomotic leakage among three different types of TDT; the time of first drainage and defecation of the Fr32 silicone tube was significantly earlier than that of Fr24 silicone tube and Fr24 latex tube. CONCLUSION: The drainage effect of the Fr32 silicone tube is better than that of Fr24 silicone tube and Fr24 latex tube after anterior resection for rectal cancer, Fr32 silicone may better prevent the occurrence of AL, but randomized controlled studies are needed.
