ABSTRACT

Introduction: Symptomatic Meckel’s diverticulum during pregnancy and inverted Meckel’s (“ windsock ”) divertic- ulum are rare occurrences. Preoperative diagnosis is difficult, and inverted diverticulum can be misdiagnosed as lipoma.

Case Description: We report a case of Meckel’s diverticulum during pregnancy, causing a hernia of the small intestine, and a case of inverted Meckel’s diverticulum causing an ileocolic intussusception.

Discussion: When dealing with small-bowel obstruction of unknown origin, Meckel’s diverticulum is a cause that is easy to miss. Early laparoscopic exploration helps as an auxiliary diagnostic tool and can avoid small-bowl necrosis or intestinal perforation caused by long-standing small bowel obstruction.

Key Words: Bowel malformation, Laparoscopic surgery, Meckel’s diverticulum, Pregnancy.
