RESUMO
The most common causes of small bowel obstruction (SBO) are adhesions, Crohn's disease, neoplasms, and hernias. Internal hernias are rare, and they occur when the small bowel herniates through a defect in the abdominal cavity. The occurrence of internal hernias due to a broad ligament defect is very rare and accounts for 4%-7% of cases of internal hernia. We present a case of a 71-year-old female who was previously healthy with no significant past medical or surgical history and who presented with symptoms of small bowel obstruction. Imaging with X-ray and computed tomography (CT) confirmed the diagnosis, but not the etiology. A decision was made to perform a laparoscopy to manage the obstruction, which revealed a healthy small bowel loop that herniated through a defect in the right broad ligament. Acute abdominal pain due to intestinal obstruction is a relatively common surgical emergency. Internal hernias are the consequence of the herniation of a bowel loop, most commonly the small bowel, through a peritoneal or mesenteric defect into a compartment in the abdominal and pelvic cavity, and they have a high mortality rate than can be higher than 50%. CT imaging is very useful in the diagnosis of internal hernias, although it may not always reveal the etiology. To facilitate wider recognition, broad ligament hernia should be in the differential diagnosis of internal hernias evident in the pelvis on CT imaging. Early recognition of small bowel obstruction caused by broad ligament internal hernia allows for prompt surgical management and vastly facilitates postoperative recovery. Although most surgeons opt for a laparotomy approach to manage such cases, a laparoscopic approach is feasible.
