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.

PURPOSE: The impact of previous abdominal surgery (PAS) on surgical outcomes from laparoscopic and robot surgeries is inconclusive. This study aimed to investigate the impact of PAS on perioperative outcomes from laparoscopic and robotic colorectal surgeries. METHODS: From March 2007 to February 2014, a total of 612 and 238 patients underwent laparoscopic and robotic surgeries, respectively. Patients were divided into 3 groups: those who did not have a PAS (NPAS), those who had a major PAS, and those who had a minor PAS. We further divided the patients so that our final groups for analysis were: patients with NPAS (n = 478), major PAS (n = 19), and minor PAS (n = 115) in the laparoscopy group, and patients with NPAS (n = 202) and minor PAS (n = 36) in the robotic surgery group. RESULTS: In the laparoscopy group, no differences in the conversion rates between the 3 groups were noted (NPAS = 1.0% vs. major PAS = 0% vs. minor PAS = 1.7%, P = 0.701). In the robotic surgery group, the conversion rate did not differ between the NPAS group and the minor PAS group (1.0% vs. 2.8%, P = 0.390). Among the groups, neither the operation time, blood loss, days to soft diet, length of hospital stay, nor complication rate were affected by PAS. CONCLUSION: PAS did not jeopardize the perioperative outcomes for either laparoscopic or robotic colorectal surgeries. Therefore, PAS should not be regarded as an absolute contraindication for minimally invasive colorectal surgeries.

PURPOSE: A diverting stoma is known to reduce the consequences of distal anastomotic failure following colorectal surgery. The aim of this study was to evaluate the efficacy of a diverting stoma after an ultra-low anterior resection (uLAR) for rectal cancer. METHODS: Between 2000 and 2007, 836 patients who underwent an uLAR were divided into two groups, depending on the fecal diversion: 246 received fecal diversion, and 590 had no diversion. Patient- and disease-related variables were compared between the two groups. RESULTS: Thirty-two of the 836 patients (3.8%) had immediate anastomosis-related complications and required reoperation. Anastomosis leakage comprised 72% of the complications (23/32). The overall immediate complication rate was significantly lower in patients with a diverting stoma (0.8%, 2/246) compared to those without a diverting stoma (5.1%, 30/590; P = 0.005). The fecal diversion group had lower tumor location, lower anastomosis level, and more preoperative chemo-radiation therapy (P < 0.001). In total, 12% of patients in the diverting stoma group had complications either in making or reversing the stoma (30/246). CONCLUSION: The diverting stoma decreased the rate of immediate anastomosis-related complications. However, the rate of complications associated with the diverting stoma was non-negligible, so strict criteria should be applied when deciding whether to use a diverting stoma.
