Combined stoma reversal and liver resection: a matched case-control study

Area of Science:

• Hepatobiliary Surgery
• Colorectal Surgery
• Surgical Oncology

Background:

• Colorectal liver metastases (CRCLM) patients with prior diverting loop ileostomy may undergo stoma reversal during liver resection (LR).
• This combined procedure (LR and loop ileostomy closure - LIC) is often perceived to increase postoperative morbidity.

Purpose of the Study:

• To investigate the impact of simultaneous LR and LIC on the postoperative outcomes in patients with CRCLM.
• To evaluate the safety and morbidity associated with the combined procedure compared to LR alone.

Main Methods:

• Retrospective analysis of a prospective database of 408 patients undergoing LR for CRCLM (November 1996 - April 2012).
• Patients undergoing simultaneous LR and LIC (n=24) were matched with LR-only patients (n=72) based on procedure type, preoperative chemotherapy use, and duration.
• Comparison of intraoperative and postoperative complications between the two groups.

Main Results:

• The study identified 24 patients (6%) who underwent simultaneous LR and LIC, matched with 72 patients who had LR only.
• Demographics and intraoperative findings were comparable between the groups.
• No significant difference was observed in liver-related morbidity (P = .957) or overall postoperative morbidity (P = .643) between the simultaneous LR and LIC group and the LR-only group.

Conclusions:

• Simultaneous liver resection and loop ileostomy closure is a safe procedure for select patients with colorectal liver metastases.
• Adherence to strict surgical technique is crucial for ensuring the safety of this combined approach.
