Evaluation of laparoscopic surgery for small bowel obstruction and factors related to outcomes.

INTRODUCTION

In recent years, laparoscopic surgery (LS) has been performed for small bowel obstruction (SBO). However, the indications and short-term and long-term outcomes of LS for SBO have not yet been established.

AIM

To evaluate the usefulness of LS for SBO compared to open surgery (OS), as well as to identify risk factors for poor outcomes after LS.

MATERIAL AND METHODS

A total of 105 patients who underwent surgery for SBO were divided into OS (n = 64) and LS (n = 41) groups, and propensity score-matched analysis was used to compare the short-term and long-term outcomes of the groups. Risk factors for conversion to OS, postoperative complications, and intraoperative bowel injury in LS were also identified.

RESULTS

The incidences of surgical site infection and postoperative ileus were significantly lower in the LS group. The incidence of recurrent bowel did not differ significantly between the two groups. Prior bowel obstruction was a risk factor for conversion of LS to OS (odds ratio (OR) = 24.79, p = 0.0025). Bowel diameter was a risk factor for postoperative complications (OR = 1.50, 95% CI: 1.01-2.22) and for bowel injury (OR = 1.33, 95% CI: 1.05-1.67).

CONCLUSIONS

LS for SBO had better postoperative short-term outcomes than OS. The outcomes of LS for SBO were significantly affected by prior bowel obstruction and bowel diameter.
