This review article comprehensively delves into the clinical features, diagnosis, and management of OH, with a particular emphasis on the pivotal role of computed tomography (CT) in timely and accurate diagnosis. Delays, particularly in contrast-enhanced CT, dramatically increase mortality due to potential bowel strangulation. To illustrate the challenges and complexities surrounding OH, we present a video vignette of a 74-year-old female patient who presented with symptoms suggestive of bowel obstruction (BO) secondary to a strangulated left-sided OH. This patient case complements the theoretical framework established in the review, serving as a practical example for healthcare professionals. Her presentation included abdominal pain, absence of flatus and bowel movements, and abdominal distension. Laboratory tests demonstrated a mildly elevated white blood cell count and C-reactive protein. CT imaging confirmed the diagnosis of a strangulated OH with an ischemic small bowel. An emergency laparoscopy was undertaken, and the hernia was repaired using the transabdominal preperitoneal approach. A portion of the ischemic small bowel was resected through a 5-cm extension of the umbilical port, and an anastomosis was performed using a modified Barcelona technique. The surgery was successfully completed without immediate or long-term complications.
