Clinical outcomes of minimally invasive surgery for Meckel diverticulum: a multicenter study.

PURPOSE

Meckel diverticulum (MD), caused by an obliteration defect of the omphalomesenteric duct, is one of the most common congenital anomalies of small intestines. The objective of this study was to review surgical outcomes of MD and evaluate the feasibility of minimally invasive surgery (MIS) in MD.

METHODS

We performed a retrospective analysis of the medical records of patients who underwent diverticulectomy for MD at 6 Hallym University-affiliated hospitals between January 2008 and December 2017. All patients underwent either open surgery or MIS. Patients who underwent MIS were subdivided into laparoscopic only diverticulectomy (LOD) or laparoscopic-assisted diverticulectomy (LAD).

RESULTS

Of 64 patients, 21 underwent open surgery and 43 underwent MIS. Time to flatus, time to soft food intake, and length of hospital stay were shorter in the MIS group than in the open surgery group (P = 0.047, P = 0.005, and P = 0.015, respectively). Among patients who underwent MIS, the time to flatus and time to soft food intake were longer in the LAD group than in the LOD group (0.3 and 0.9 days, respectively). Multivariate analysis showed that old age and preoperative ileus were independent predictors of complications (P = 0.030 and P = 0.013, respectively). Operation type (open surgery, LOD, or LAD) was not associated with complications.

CONCLUSION

The present study showed that MIS is associated with quicker recovery without increasing complications. Therefore, MIS may be a safe alternative to open surgery for MD. An old age and preoperative ileus were associated with a risk of postoperative complications.
