Endometriosis, mucocele, and regional enteritis of Meckel's diverticulum. An unusual case report and experiences in 111 cases

A Case of Endometrial Tissue Containing Meckel's Diverticulum in an Adult

A Meckel's diverticulum is one of the most common congenital causes of small bowel obstruction. The lack of a more common gastric-containing tissue and older age of symptom onset can lead to difficulties with preoperative diagnosis. This case demonstrates an adult with chronic abdominal pain with recurrent small bowel obstruction that was found to be a rare ectopic endometrial tissue containing a Meckel's diverticulum following a diagnostic laparotomy. The barriers to diagnostics and factors affecting the age of onset are discussed with a focus on demonstrating the importance of surgical intervention for small bowel obstruction due to a Meckel's diverticulum and on the significance of a rare histological finding.

Endometriosis of the terminal ileum: a diagnostic dilemma

Endometriosis is characterized by the presence of endometrial tissue consisting of glands and/or stroma located outside the uterus. Involvement of the terminal ileum is extremely rare. Preoperative distinction of ileal endometriosis from other diseases of the ileocecal region is difficult in terms of clinical presentation, symptomatology, radiological appearance, and surgical and pathological findings. We report a case initially diagnosed as Crohn's disease due to a longstanding diarrhea with subsequent intestinal obstruction, but finally diagnosed as ileal endometriosis by histopathological evaluation after resection of the involved segment.

Surgical management of Meckel's diverticulum. An epidemiologic, population-based study

OBJECTIVE

The authors determined whether Meckel's diverticulum, discovered incidentally at operation, should be removed.

SUMMARY BACKGROUND DATA

It is not clear from the medical literature whether the risk of an incidental Meckel's diverticulectomy is greater than the risk of leaving the diverticulum in place.

METHODS

The authors used the medical experience of Olmsted County, Minnesota residents for the period 1950 to 1992 to answer the question.

RESULTS

During the period, 58 residents developed Meckel's complications that required diverticulectomies. The incidence of complications was 87 per 100,000 person-years, and the lifetime risk (to 80 years of age) of developing them was 6.4%. The risks were similar throughout the period and at all ages of life, but were greater among men (124 per 100,000 person-years) than women (50 per 100,000 person-years, p < 0.05). Diverticulectomies for complications carried an operative mortality and morbidity of 2% and 12% and a cumulative risk of long-term postoperative complications of 7%, whereas incidental diverticulectomies done in 87 residents during the period carried corresponding rates of only 1%, 2%, and 2%, respectively.

CONCLUSIONS

Meckel's diverticula discovered incidentally at operation should be removed for most patients, regardless of age.

Endometriosis. An important condition in clinical gastroenterology

Endometriosis, a condition defined by the presence of ectopic endometrium, is a disorder of increasing incidence and a significant cause of gastroenterologic distress in young women. Although clinical manifestations vary considerably depending upon the anatomic extent of disease, characteristic abdominal complaints and typical physical findings continue to be associated with misdiagnosis and delayed recognition of gastrointestinal involvement. The authors of this paper review the medical literature concerning endometriosis of the digestive tract--emphasizing modes of presentation, risk factors, diagnostic testing, complications, and therapy. Greater familiarity with the disease and heightened awareness of its sequellae are needed and prerequisite to improved medical management.

Association of Meckel's diverticulum and Crohn's disease

A significant association between Meckel's diverticulum and Crohn's disease has been suggested in the clinical literature. Ten patients with entities demonstrated radiographically as well as cases reported in the literature were analyzed to determine the relevance of this association to radiologic evaluation. The Meckel's diverticulum in most cases was an incidental finding whereas the Crohn's disease usually accounted for the patient's clinical symptoms. Recognition of this association should prevent unnecessary laparotomy for an incidental Meckel's diverticulum and improve the radiographic diagnosis of coexistent Crohn's disease.

Meckel's diverticulum: should it be excised incidentally at operation?

Meckel's diverticulum is the most common congenital abnormality of the small intestine, occurring in about 2 per cent of the population. Complications of a Meckel's diverticulum, including hemorrhage, inflammation, bowel obstruction, and neoplasms, occur in 15 to 33 per cent of cases and invariably demand operative treatment. When signs or symptoms arise from a Meckel's diverticulum, morbidity and mortality are high. Incidental Meckel's diverticulectomy should be performed at any age when the morbidity and mortality of the primary procedure will not be increased substantially.
