Sigmoid endometriosis in a post-menopausal woman leading to acute large bowel obstruction: A case report

AbstractIntroductionEndometriosis is usually a disease involving women of reproductive age. Colonic endometriosis is a rare sequelae. It usually presents vaguely with nonspecific abdominal pain, dyspareunia, fecal tenesmus, rectal bleeding or painful defecation. There are very few case reports of sigmoid endometriosis in the literature, more so ones involving post-menopausal women. Our report highlights such a case, mimicking a malignant rectosigmoid stricture leading to a large bowel obstruction.Case presentationA 63year old lady was referred by her General Practitioner for further investigation of recent altered bowel habit. She underwent an incomplete colonoscopy due to stricturing in the sigmoid. She subsequently was admitted with abdominal pain, distension and vomiting, with imaging consistent with a large bowel obstruction secondary to a stricturing mass within the rectosigmoid which was suspicious for malignancy. An emergency laparotomy and Hartmann’s procedure was performed. She had an uncomplicated post-surgical recovery. Histology revealed no underlying malignancy, but confirmed colonic endometriosis.ConclusionThis case report shows that colonic endometriosis, although rare, can be significantly infiltrative and lead to complications such as a large bowel obstruction. Diagnosing this condition can be challenging and usually requires histological confirmation

A diagnostic dilemma: Left-sided appendicitis in a 10 year old boy with previously undiagnosed intestinal malrotation. A case report

AbstractIntroductionIntestinal malrotation is a congenital rotational anomaly that occurs as a result of an arrest of normal rotation of the embryonic gut, said to occur in 1 in 6000 live births. Due to the abnormal caecal and appendix position, diagnosis of acute appendicitis becomes more challenging, thus leading to diagnostic and operative intervention delays. Our aim is to highlight the diagnostic challenges in this clinical scenario.Presentation of caseWe present a case of a 10 year old boy with previously undiagnosed intestinal malrotation with a left sided acute appendicitis. Initial symptoms lead to a treatment for gastroenteritis, however, due to ongoing pain a CT abdomen was done which showed the malrotation and appendicitis. He required a laparoscopy converted to open appendicectomy due to an appendicecal mass.DiscussionHistorically, intestinal malrotation was thought to be a disease of infancy with infrequent occurrence after the age of one year. However, recent analysis has shown an increase in presentations after one year of life into adulthood. Thus, the prevalence of malrotation in children and adults over the age of one year appear to be higher than initially presumed.ConclusionLeft sided acute appendicitis is a diagnostic dilemma, thus often leading to management delays. It is pertinent to remember that malrotation of the gut is more common than previously thought, and not just a disease of infancy. It is advisable to consider imaging studies while balancing the risk-benefit-ratio of radiation exposure, especially in paediatric cases to cinch the diagnosis

The dilemma of stump appendicitis — A case report and literature review

Introduction: Stump appendicitis is one of the rare delayed complications post appendectomy with a reported incidence of 1 in 50,000 cases. Stump appendicitis can present as a diagnostic dilemma if the treating clinician is unfamiliar with this rare clinical entity. A PubMed search was conducted to identify cases of stump appendicitis following appendectomy. Sixty one cases of SA that were reported in English medical literature were analyzed. Presentation of case: We report a case of stump appendicitis (SA) with a systematic review and challenges encountered during the management. Discussion: The interval from original appendectomy to stump appendicitis ranged from 4 days to 50 years. SA followed appendectomy in 58% of open and 31.6% of laparoscopic procedures. SA was frequently misdiagnosed as constipation, gastroenteritis or right sided diverticulitis, therefore leading to a significant delay to surgery. Computerized Tomography diagnosed SA in 56.3% of cases. Perforation with gangrene of the stump occurred in 60%. Conclusion: Stump appendicitis can represent a diagnostic dilemma if the treating physician is unfamiliar with this uncommon clinical entity. Radiological imaging is required to aid diagnosis and a completion appendectomy is the modality of treatment
