Results of a laparoscopic approach for the treatment of acute small bowel obstruction due to adhesions and internal hernias.

Introduction: Laparotomy is the standard approach for the surgical treatment of acute small bowel obstruction (ASBO).

Patients And Methods: From February 2007 to May 2012 we prospectively recorded all patients operated by laparoscopy in our hospital because of ASBO due to adhesions (27 cases) and/or internal hernia (6 cases). A preoperative abdominal CT was performed in all cases. Patients suffering from peritonitis and/or sepsis were excluded from the laparoscopic approach. It was decided to convert to laparotomy if intestinal resection was required.

Results: The mean age of the 33 patients who underwent surgery was 61.1 ± 17.6 years. 64% had previous history of abdominal surgery. 72% of the cases were operated by surgeons highly skilled in laparoscopy. Conversion rate was 21%. Operative time and postoperative length of stay were 83 ± 44 min. and 7.8 ± 11.2 days, respectively. Operative time (72 ± 30 vs 123 ± 63 min.), tolerance to oral intake (1.8 ± 0.9 vs 5.7 ± 3.3 days) and length of postoperative stay (4.7 ± 2.5 vs 19.4 ± 21 days) were significantly lower in the laparoscopy group compared with the conversion group, although converted patients had greater clinical severity (2 bowel resections). There were two severe complications (Clavien-Dindo III and V) in the conversion group.

Conclusions: In selected cases of ASBO caused by adhesions and internal hernias and when performed by surgeons highly skilled in laparoscopy, a laparoscopic approach has a high probability of success (low conversion rate, short hospital length of stay and low morbidity); its use would be fully justified in these cases.
