Trans-perineal minimally invasive approach during extralevator abdominoperineal excision for advanced low rectal cancer: A retrospective cohort study

BACKGROUND

This study is to evaluate trans-perineal minimally invasive approach for extralevator abdominoperineal excision (TP-ELAPE) in a synchronous lithotomy position for locally advanced low rectal cancer.

METHODS

Between May 2013 and February 2016, 14 patients with locally advanced low rectal cancer underwent TP-ELAPE for the perineal phase of extralevator abdominoperineal excision, and 18 patients underwent conventional ELAPE.

RESULTS

There was no positive circumferential resection margin in both groups. Patients who received TP-ELAPE had similar bowel perforation rate (7.1% vs. 5.6%, p = 1.000), longer transperineal operative time (100 vs. 40 min, p < 0.001) and higher surgical difficulty visual analog scale (VAS) scores (6 vs. 2, p < 0.001), while had shorter total procedure time (215 vs. 260 min, p = 0.015), lower VAS pain scores on day 1 postoperatively (5 vs. 6.5, p = 0.049), shorter postoperative anus exhausting time (22 h vs 28 h, p = 0.006), and shorter postoperative hospital stay (11.5 d vs 13.5d, p = 0.028) compared with patients who received conventional ELAPE. There was no local recurrence with median follow-up time of 53 months in the TP-ELAPE group and 51 months in the conventional ELAPE group. There were no differences for disease-free survival (p = 0.835) and overall survival (p = 0.829) between groups.

CONCLUSIONS

TP-ELAPE approach in the synchronous lithotomy position might be a feasible approach for low rectal cancer, while ensuring a radical and safe surgical procedure.

Circumferential resection margins and perineal complications after neoadjuvant long-course chemoradiotherapy followed by extralevator abdominoperineal excision of the rectum: Five years of activity at a single institution

BACKGROUND

Prone extralevator abdominoperineal excision of the rectum (ELAPE) has been introduced to improve the circumferential resection margins (CRM) compared with traditional APER.

OBJECTIVE

We present short-term results achieved with prone ELAPE preceded by neoadjuvant chemoradiotherapy during the last 5 years of activity.

DESIGN

A retrospective review was conducted.

SETTINGS AND PATIENTS

Prone ELAPE operations performed between September 2010 and August 2014 at Leicester Royal Infirmary preceded by neoadjuvant chemoradiotherapy.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Data regarding demographics, staging, neoadjuvant therapies, intraoperative perforations, and perineal complications were collected.

RESULTS

Seventy-two patients were included. Pretreatment radiological T4 were 25.0%, histological T4 2.8%. Intraoperative perforations occurred in 2.8%, CRM was involved in 11.1%. Perineal complications consisted of superficial wound infections (20.8%), full thickness dehiscences (16.7%), hematomas (9.7%), pelvic collections (6.9%), and perineal hernias (5.6%).

CONCLUSIONS

In our experience, prone ELAPE preceded by long-course chemoradiotherapy has been successfully used in the last 5 years to resect low rectal tumors. Perineal wound complications rates are similar to those presented in series using direct perineal closures. J. Surg. Oncol. 2016;114:86-90. © 2016 Wiley Periodicals, Inc.
