OBJECTIVE: Anastomosis leakage in laparoscopic surgery for rectal cancer is still a serious problem affecting the patient’s treatment outcome. This study aimed to evaluate the role of a transanal drainage tube compared with a diverting stoma in reducing the rate of anastomosis leakage and limiting surgical complications.

PATIENTS AND METHODS: A retrospective study was conducted on 196 rectal cancer patients undergoing laparoscopic low anterior resection from July 2018 to October 2022 at 108 Central Military Hospital. The transanal drainage tube was placed in 133 patients (group A), and diverting stoma was performed in 63 patients (group B).

RESULTS: There was no difference between the two groups regarding age, sex, comorbidities, distance from the tumor to the anal verge, and preoperative stage. The amount of blood loss, the method of performing the anastomosis, and the distance from the anastomosis to the anal verge did not differ between the two groups. However, the surgical time was longer in the group with diverting stoma (138.3 ± 25.1 minutes vs. 127.6 ± 31 minutes, p = 0.018). The rate of anastomosis was not significantly different between groups A and B (8.3% in group A and 7.9% in group B, p = 0.936). The proportion of patients with anastomosis requiring reoperation in group A was higher than in group B. However, the difference was not statistically significant (8/11 patients in group A and 2/5 patients in group B, p = 0.29).

CONCLUSIONS: Placing a transanal drainage tube in laparoscopic surgery for rectal cancer to reduce the rate of anastomosis can be considered an alternative method for diverting stoma with complications related to the stoma.
