What are the results of colonic volvulus surgery?

Abstract

Background: Operative results of volvulus are largely unknown because of infrequent diagnosis.

Objective: We examined the results of operative intervention for colonic volvulus.

Design: We merged trackable data from the California Inpatient Database with Supplemental Files for Revisit Analyses between January 1, 2005, and December 31, 2007.

Settings: Trackable data from California discharge records.

Patients: We identified all of the patients with colonic volvulus who underwent 1 of 4 surgical procedures, including manipulation/fixation of the colon, right colectomy, left colectomy, or total colectomy.

Main outcome measures: During the 36-month study period, we identified recurrence risk, recurrence requiring reoperation, time to reoperation, stoma formation, disposition on discharge, and in-hospital mortality. Fisher exact, χ(2), and ANOVA tests were used when appropriate.

Results: We identified 2141 patients with colonic volvulus who were undergoing intraoperative manipulation/fixation of the colon (n = 209 (12%)), right (n = 728 (41%)), left (n = 781 (44%)), or total colectomy (n = 56 (3%)). Patients treated with intraoperative manipulation/fixation were younger, more likely to be women, and more likely to have private insurance. Patients who underwent total colectomy had the highest risk of mortality (21%), highest risk of stoma creation (64%), and longest length of stay (18 days); were more likely to be readmitted (9%); and were the most likely to be discharged to a skilled nursing facility (48%). Patients treated with intraoperative manipulation/fixation had the lowest mortality, risk of stoma formation, length of stay, and likelihood of discharge to skilled nursing facility but the highest risk of subsequent procedures for volvulus (26%) over a follow-up ranging from 0 to 687 days.

Limitations: This study was limited by retrospective study design, heterogeneous patient factors, and inability to identify the time of last follow-up.

Conclusions: The majority of patients with volvulus underwent a resectional procedure. A subset without resection had favorable initial outcomes but remained at high risk for subsequent procedures. There may be a potential role for evaluating intraoperative manipulation/fixation in a small subset of patients with colonic volvulus.
