Abstract
PURPOSE
Proper transection of the distal rectum is important for reconstruction of bowel continuity in rectal cancer surgery. In this study, we introduced a modified technique for ligation of the distal rectum, and investigated its safety and efficiency to facilitate the rectum transection.
METHODS
After complete mobilization and transection of the mesorectum, a cable tie was carefully positioned distal to the tumor, followed by washout and transecting the rectum with a linear stapler. From September 2017 to June 2018, consecutive 67 mid-low rectal cancer patients with laparoscopic anterior resection underwent this technique. Clinical data of these patients, including number of firings, pathological and operative variables, and postoperative outcomes, were compared with those of 132 consecutive patients who underwent traditional surgery from January 2016 to August 2017.
RESULTS
Compared with the traditional method, cable tie ligation significantly reduced the number of firings (1.1 ± 0.32 vs. 1.3 ± 0.52, p < 0.001). A very high ratio of one firing transection of rectum was observed in the cable tie group (94.0% vs. 68.9%, p < 0.001), even in patients with tumor at or below the peritoneal reflection (90.2% vs. 54.4%, p < 0.001), in male patients (95.5% vs. 65.8%, p < 0.001), and in obese patients (93.8% vs. 64.9%, p = 0.005). The mean distal margin was longer in the cable tie group (3.19 ± 1.77 cm vs. 2.54 ± 1.36 cm, p = 0.005), with no positive distal margin observed. The operation time, quality of mesorectum, and morbidity between two groups were comparable. Two leaks (3.0%) in the cable tie group were observed, similar to 3.8% in the control.
CONCLUSIONS
Ligation of the rectum with a cable tie reduces the number of cartridges, and increases the rate of one stapler firing for rectal transection, even in those difficult cases like male, overweight, and low rectal cancer patients. It is also useful for occlusion of the rectum before washout. It is safe, feasible, and worthwhile for popularization.
