Meckel's diverticulum--a rare cause of intestinal obstruction in adults.

Although many people have Meckel's diverticulum, only some experience any symptoms, most under the age of 10. In adults it is usually asymptomatic but approximately 4% develop complications. Meckel's diverticulum is usually diagnosed in the first years of life and after that the risk of the complications decreases with increasing age, with no predictive factors for the development of complications. We describe the case of a 34-year-old man admitted in the emergency department with diffuse abdominal pain, nausea, flatulence and lack of transit for feces and gas. The patient had been previously operated for peritonitis due to a perforated ulcer. Clinical examination and paraclinical investigations (abdominal radiography and ultrasound) suggested the diagnosis of intestinal obstruction, probably produced by adhesions due to previous abdominal intervention. The diverticulum was resected using a linear stapler and the patient recovered without any complications. Small bowel obstruction due to Meckel's diverticulitis may be caused by entangled loop of small bowel around a fibrous cord, intussusception, volvulus, or incarceration within a hernia sac. The discovery of a Meckel's diverticulum complication in a mid thirties patient represented an intra-operatory surprise and is the peculiarity of the case.
