Background: Laparoscopic ELAPE surgery has been carried out in our center for a long time, and some modifications have been made in clinical practice. In this study, we compared conventional ELAPE operation with modified ELAPE operation to investigate the efficacy and safety of modified ELAPE operation.
Methods: We retrospectively analyzed the data from 339 patients with low rectal cancer undergoing abdominoperineal resection from 2017 to 2021 in the Department of General Surgery, Qilu Hospital of Shandong University. Patients were classified into modified ELAPE groups (199 patients) and conventional ELAPE groups (140 patients). Total operation time, reconstruction time, postoperative hospital stay, total cost, intraoperative data, postoperative short-term and long-term complications and tumor recurrence were compared.
Results: The baseline characteristics were comparable between the two groups. Total operation time was less with modified ELAPE group compared to conventional ELAPE group (190.6 ± 33.1 min vs 230.1 ± 51.6 min, P = 0.022). Pelvic floor reconstruction time was also less with modified ELAPE group compared to conventional ELAPE group (4.3 ± 1.2 min vs 11.9 ± 1.7 min, P = 0.004). Positive CRM was observed in 11 and 9 patients in modified ELAPE groups and conventional ELAPE groups (P = 0.744). IOP occurred in 12 and 7 patients in modified ELAPE group and conventional ELAPE group (P = 0.701). Total cost was also less with modified ELAPE group compared to conventional ELAPE group (9004 ± 1146 USD vs 10,336 ± 2047 USD, P = 0.031). The incidence of parastomal hernia was less with modified ELAPE group compared to conventional ELAPE group (7/199 vs 22/140, P < 0.001). Three-year follow-up data did not show any difference in overall survival rate or local occurrence between the two groups.
Conclusion: Modified ELAPE surgery is technically safe and feasible, and oncologically comparable to that of conventional ELAPE surgery, which can be considered for popularization and application.

Exploring the surgical effectiveness and post-operative recovery of modified laparoscopic levator ani muscle external abdominoperineal resection (L-ELAPE) in the treatment of ultra-low rectal cancer patients. In a retrospective study conducted at the Oncology Department of Xinxiang Central Hospital and the Fourth Clinical College of Xinxiang Medical University, we analyzed 107 patients with ultra-low rectal cancer who underwent surgical treatment from April 2017 to April 2022. Among them, 54 patients in the modified group were treated using the L-ELAPE technique, while 53 patients in the conventional group underwent the traditional ELAPE surgery.

Methods: we enrolles patients with extraperitoneal rectal cancer undergoing TME or TME+APE. Patients with mid rectal tumors underwent TME, and patients with tumors of the lower rectum and no criteria for APE underwent TME and intersphincteric resection.

This study was performed to retrospectively analyze and compare the related clinical indicators between extralevator abdominoperineal excision (ELAPE) and non-ELAPE under laparoscopic for low rectal cancer. From June 2018 to September 2021, a total of 80 patients with low rectal cancer who underwent either of the above two types of surgeries at our Hospital were enrolled. Patients were divided into the ELAPE group and non-ELAPE group based on the different surgical methods.

Background: At present, abdominoperineal excision with neoadjuvant chemoradiotherapy (nCRT) is one of the treatment modalities of distal rectal cancer. Our study analyzed the effects of laparoscopic extralevator abdominoperineal resection (ELAPE) compared with laparoscopic conventional abdominoperineal resection(cAPR) in the treatment of distal rectal cancer.
Methods: Retrospective analysis was conducted on the clinicopathological data of 177 distal rectal cancer patients treated with a laparoscopic abdominoperineal resection between 2011 and 2018.
