Robotic multivisceral pelvic resection: experience from an exenteration unit.

Abstract

Pelvic exenteration remains a viable and effective treatment option for the management of locally advanced or recurrent pelvic malignancy. The aim of this study was to present an early experience of robotic multivisceral resection of pelvic malignancy, and to compare this experience with similar series through a systematic review of the literature. A retrospective study was performed on patients who had robotic-assisted multi-visceral resection for pelvic malignancy at a single Colorectal Surgical unit based between two tertiary academic hospitals. Primary outcomes observed included operation type, operation time, perioperative complications, and hospital length of stay. Secondary outcomes included R0 resection status, lymph node harvest, and rate of recurrence at clinical follow-up. Eight cases of robotic multivisceral resection were performed for primary locally advanced pelvic malignancy involving a rectal resection as part of their operative management. The median age of patients undergoing resection was 56years (range 29-83years). The male:female ratio was 6:2. The mean total operating time was 8.3h (range 6-10h). Perioperative blood transfusion requirements were minimal. Mean hospital length of stay was 15days (range 7-26days). No patients experienced any serious postoperative morbidity or mortality. All patients had clear margins on histological assessment and no patients have recurrence at 12-month follow-up. Robotic multivisceral resection for malignant disease of the pelvis is a safe and feasible minimally invasive approach in highly selected cases.
