Question 9#

The most common cause of small bowel obstruction is:

A. Incarcerated hernia
B. Crohn's disease
C. Malignancy
D. Postoperative adhesions

Correct Answer is D


Intra-abdominal adhesions related to prior abdominal surgery accounts for 75% of cases of small bowel obstruction. Cancer-related small bowel obstruction is almost always due to extrinsic compression or entrapment of the bowel by a primary or metastatic tumor; primary small bowel malignancies are rare.
