IntroductionIntussusception of the appendix is an extremely rare condition that ranges from partial invagination of the appendix to involvement of the entire colon. Endometriosis is an exceptionally rare cause of appendiceal intussusception and only very few cases have been reported in the literature to date.Case presentationA 40 year-old woman presented to clinic with a long history of lower abdominal pain, loose motions and painful, heavy periods. Subsequent colonoscopy revealed submucosal endometriotic nodules in the sigmoid as well as a polyp thought to be arising from the appendix, which had inverted itself. She was referred to a colorectal surgeon because the polyp could not be removed endoscopically despite several attempts. At laparotomy, the appendix had intussuscepted but it was possible to reduce it and therefore a simple appendicectomy was carried out. On histology, there were widespread endometrial deposits within the wall of the appendix and this was thought to be the basis for the intussusception.ConclusionHistological evidence of the lead point is of crucial importance in cases of appendiceal intussusception, in order to exclude an underlying neoplastic process. Consequently, surgical resection is necessary either through an open or a laparoscopic approach. Gastrointestinal endometriosis should be considered as a cause of appendiceal intussusception in post-menarchal women with episodic symptoms and proven disease.
A 50-year-old male with a 7 month history of progressive dysphagia to solids then subsequently to liquids. He underwent a diagnostic gastroscopy which was normal. A further barium swallow suggested achalasia. He was referred to a tertiary centre, where he underwent pH and manometry studies which confirmed a diagnosis of achalasia. He was referred for a laparoscopic cardiomyotomy, and at surgery there was a suspected tumour at the gastro-oesophageal junction. A follow-up endoscopy with biopsies was normal. Following this, a positron emission tomography scan showed T3 distal oesophageal cancer with no nodal involvement or distal metastasis. An attempt at oesophagectomy was performed, but at operation there was locally advanced carcinoma infiltrating the coeliac axis. He is currently undergoing palliative chemotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
