Paraduodenal hernias are rare congenital internal hernias accounting for <2% of intestinal obstruction. Left paraduodenal hernias (LPDHs) into the fossa of Landzert are the more common type and result from abnormal rotation of the midgut and failure of peritoneal fusion. Sequelae of these hernias usually occur spontaneously in the 4th or 5th decade of life and are more common in males and have a significant risk of incarceration and subsequent strangulation. We describe a case of a 15-year-old female who develops a LPDH following laparoscopic appendectomy, resulting in jejunal incarceration and subsequent small intestinal obstruction. The patient discussed is from an atypical demographic, being young and female. In addition, the precipitating event prompting incarceration of the hernia appears to be the application of pneumoperitoneum, placement in the Trendelenburg position, and manipulation of small intestine for the purpose of facilitating laparoscopic appendectomy. To our knowledge, this is the first reported case of LPDH exacerbated by laparoscopic procedure.
