Cecal endometriosis presenting as acute appendicitis

Cecal Endometriosis Presenting as Hematochezia in a Postmenopausal Female

Our report highlights the diagnosis of cecal endometriosis as a unique cause of hematochezia in a postmenopausal female. Cecal endometriosis manifesting as intermittent hematochezia and abdominal pain is uncommon but requires prompt clinical diagnosis and management. We report a case of cecal endometriosis causing hematochezia and subsequent syncope, which prompted the patient's admission to the emergency department. In our patient, a diagnosis of cecal endometriosis was made after a colonoscopy, with multiple biopsies confirming the presence of endometrial tissue embedded in the cecum. We aim to bring awareness of cecal endometriosis presenting as hematochezia in a postmenopausal woman with a history of abdominal pain. This case highlights intestinal endometriosis as a differential diagnosis to be considered in women, regardless of age, with intermittent hematochezia and abdominal pain.

A case of infiltrative cecal endometriosis with appendiceal obliteration and lymph node involvement

Endometriosis is a clinical condition with a wide spectrum of severity, and a subset that includes intestinal involvement that may even mimic malignancy, making non-surgical diagnosis difficult. Cecal endometriosis is a rare finding among intestinal endometriosis. We report on 33-year-old woman with ileocecal endometriosis presenting as endoscopic prolapse of the ileocecal valve associated with a mass on cross-sectional imaging. The diagnosis was suggested intraoperatively by peritoneal endometrioma and obliteration of the appendix during laparoscopic right hemicolectomy. Pathological review demonstrated extensive submucosal, infiltrative endometriosis with mass effect and lymph node involvement. This case highlights the difficulty in preoperative diagnosis of intestinal endometriosis and the wide-ranging potential tissue effects in cases of infiltrative disease.

Characteristic findings of appendicular endometriosis treated with single incision laparoscopic ileocolectomy: Case report

INTRODUCTION

We report the case of characteristic findings of appendicular endometriosis that presented as a submucosal tumor in the cecum without any abdominal symptoms treated with single-incision laparoscopic ileocolectomy.

PRESENTATION OF CASE

The patient was a 51-year-old woman (body mass index: 21.5) who underwent an examination to investigate the cause of a positive fecal occult blood test. Her laboratory test results were normal, without anemia or tumor marker elevation. Colonoscopy revealed a submucosal tumor in the cecum. Enhanced computed tomography (CT), fluorodeoxyglucose-positron emission tomography-CT and magnetic resonance imaging failed to produce a clear diagnosis. Given the malignant potentiality of the tumor, ileocolectomy was considered potentially necessary, but she wished for minimally invasive surgery. She ultimately underwent ileocolectomy and lymphadenectomy with single-incision laparoscopic surgery. A pathological examination revealed the lesion to be appendicular endometriosis, and 14 lymph nodes with no malignancy were resected.

CONCLUSION

Appendicular endometriosis can present as a submucosal tumor in the cecum without any abdominal symptoms. Appendicular endometriosis should be considered in the differential diagnosis of ileocecal submucosal tumor. Single-incision laparoscopic ileocolectomy was useful procedure for cecum tumor resection.

Primary cecal pathologies presenting as acute abdomen and critical appraisal of their current management strategies in emergency settings with review of literature

Background:

The importance of cecal pathologies lie in the fact that being the first part of the large intestine, any disease involving the cecum affects the overall functioning of the large bowel. Primary cecal pathologies presenting as acute abdomen have not been described in any previous study in terms of presentation, management, and outcome.

Objectives:

The objective of this study was to identify the reported causes of primary cecal pathologies presenting as acute abdomen and the various causes presenting in our setting, the to discuss morbidity and mortality associated with cecal pathologies, and to critically analyze the various management modalities employed in an emergency setting.

Materials and Methods:

This is a retrospective analysis of a prospectively collected data of all adult patients admitted to our unit in the last 10 years for acute abdomen, in whom cecal pathology was identified as the primary offending agent.

Results:

Our analysis of 43 patients revealed cecal perforation secondary to amebic colitis along with the simultaneous presence of liver abscess to be the most common primary cecal entity met in practice as acute abdomen. Other pathologies that were encountered included volvulus, diverticulitis, and idiopathic typhlitis. Primary acute cecal pathologies are associated with high mortality rates (≈42%). Delay in diagnosis seems to be the most important factor contributing to high mortality as these conditions are commonly misdiagnosed as appendicular pathology. Most of our patients were managed by conservative colonic resection with proximal diversion. This seems to be a more plausible option in current practice in an emergency setting (mortality rate ≈ 36%) as hemicolectomy is associated with proportionately higher mortality rates (67%).

Conclusion:

A high index of suspicion, timely and adequate pre-operative workup, optimal resuscitation, and surgical conservatism with proximal diversion might help in early accurate identification of these conditions and possibly improved outcome.
