[Application of electric tube stapler in laparoscopic colorectal tumor surgery]

Objective: To investigate the application of electric tube stapler in laparoscopic colorectal tumor surgery. Methods: A descriptive case series study was conducted. Clinical data of patients who underwent laparoscopic colorectal surgery in Peking Union Medical College Hospital in August 2021 using domestic electric tube stapler were collected to analyze the occurrence of postoperative anastomotic leakage, anastomotic bleeding and other complications as well as postoperative intestinal function recovery. Results: A total of 11 patients with colorectal tumor were enrolled in this study, including 8 males and 3 females. Eight patients underwent laparoscopic low anterior resection (1 patient underwent protective ileostomy), and three patients underwent laparoscopic sigmoid carcinoma radical resection. During operation, power system failure of stapler occurred in 1 patient, and the replacement manual device was used to complete the anastomosis. No anastomotic leakage or bleeding occurred in the cohort of patients. There was no conversion to laparotomy or conventional anastomosis. One patient developed acute myocardial infarction 2 days after surgery. The average time to the first flatus after surgery was (2.4±0.8) days and the average length of hospital stay was (10.0±6.1) days. Conclusions: The application of electric tube stapler in laparoscopic colorectal tumor surgery has many advantages, such as safe and effective anastomosis, low morbidity of postoperative complications, and rapid recovery of intestinal function. Domestic electric tube stapler can be applied in minimally invasive surgery for colorectal tumor.
