High Grade Intestinal Obstruction From Internal Hernia Beneath an Intraperitoneal External Iliac Artery.

Acute small bowel obstruction (SBO) is a common cause of emergency department visits in the United States, and it accounts for approximately 20% of emergency surgical operations. Its etiology is divided into intrinsic luminal obstruction or extrinsic compression of the bowel. Among the causes of SBO, by far the most common is intraperitoneal adhesions due to previous abdominal surgeries, which comprises about 60-70% of the cases.

Perforated Sigmoid Diverticulitis Within a Strangulated Inguinal Hernia.

We present a rare case of perforated diverticulitis within an inguinal hernia sac adjacent to a synthetic mesh from a prior incisional hernia. An 80-year-old-female presented to the ED with abdominal pain. Cross-sectional imaging was significant for a small bowel obstruction with a transition point in the right lower quadrant (RLQ).
