Clinical Features of Strangulated Small Bowel Obstruction
Overview
Affiliations
Purpose: The causes of strangulated small bowel obstruction (SSBO) include a fibrous cord, torsion, and internal hernia. We conducted this study to define the clinical features of SSBO.
Methods: We reviewed the clinical course and preoperative data of 74 patients treated for SSBO in Kumamoto Regional Medical Center between January 2004 and September 2010.
Results: Twenty-one patients had no history of laparotomy. Computed tomography (CT) showed high positivity (86.3 %) of closed loops in the involved intestine. Postoperative complications developed in 23 patients, representing a morbidity rate of 31.1 %. Forty-four patients underwent resection of non-viable small intestine (non-viable group), and 30 did not require resection of the intestine (viable group). There were four hospital deaths in the non-viable group. The overall mortality rate and the mortality rate in the non-viable group were 5.4 and 9.1 %, respectively.
Conclusion: These findings indicate that SSBO can occur without a history of laparotomy, CT is useful in its diagnosis, and its associated morbidity and mortality are high.
