Introduction: Conventional abdominoperineal resection (APR) has a high rate of local recurrence. Extralevator abdominoperineal excision (ELAPE) can potentially diminish the rate of intraoperative tumour perforation (IOTP) and can provide wider circumferential resection margins (CRM) but at the price of higher perineal complication rate. The aim of our study was to compare the short term results of conventional APR to ELAPE.
Materials And Methods: Thirty-five consecutively operated APRs compared to 38 also consecutively operated ELAPEs. Prospectively collected short-term outcome data were analysed retrospectively.
Results: There was no difference in demographics, disease stage or tumour location between groups. IOTP rate and CRM positivity rates were similar between the two groups ( = .608). No difference was found in major (Clavien-Dindo III-V) complications, but we found statistically significant difference in minor (Clavien-Dindo I-II) complications ( = .01) in favour of the ELAPE group. Frequency of perineal SSI was lower in ELAPE group, but the difference was not significant ( = .320). Intraoperative iatrogenic complications occurred at significantly lower rate in ELAPE group ( = .035). Also, postoperative morbidity connected with the dissection in the perineal phase (e.g. urine incontinence, urinary retention) was significantly lower ( = .018) after ELAPE.
Discussion And Conclusions: In our experience ELAPE operations may diminish the rate of Clavien-Dindo I-II complications compared to conventional APR. This effect is ensuing from the decrease of intraoperative iatrogenic complications and from the decrease of minor postoperative complications.

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.

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.
