- An Alarming Mimicry of Intra-Abdominal Infections: Acute Appendiceal DiverticulitisKim, Youseung; Kesar, Varun; Grider, Douglas J.; Chitnavis, Maithili V. (Hindawi, 2021-11-12)A 65-year-old woman presented with three days of colicky abdominal pain. Abdominal imaging illustrated small bowel enteritis, ascites in both paracolic gutters, and incidental hepatic steatosis. Although ascites fluid demonstrated high neutrophil count consistent with peritonitis and the patient received adequate antibiotics, she clinically deteriorated. Subsequent exploratory laparotomy revealed necrotic appendix and multiple intra-abdominal abscesses. Histopathology showed acute suppurative appendicitis with multiple other intact small diverticula, indicating likely perforation of inflamed appendiceal diverticula with subsequent abscess formation and abdominal peritonitis. This case highlights the importance of ascites fluid analysis and continued clinical correlation, especially in cases of rare entities with atypical presentations.
- Bleeding Gastric Lipoma Resected by Endoscopic Submucosal DissectionMir, Adil Shamim; Kesar, Varun; Sageer, Mohamed; Grider, Douglas J.; Chitnavis, Vikas (2020-06-29)Gastric lipomas are slow-growing benign lesions of the stomach that are often detected incidentally. Most cases are asymptomatic but larger lesions may become symptomatic, thereby requiring treatment. Multiple endoscopic modalities have been used for resection in the past. We present the case of a 67-year-old patient who presented with upper GI bleeding secondary to a gastric lipoma, which was successfully resected by endoscopic submucosal dissection.

- A Rare Case of Eosinophilic Gastroenteritis Isolated in the Muscularis Propria of the Small BowelKim, Seo Hyun; Kesar, Varun; Grider, Douglas; Nguyen, Vu (Cureus, 2021-10-14)Eosinophilic gastroenteritis (EG) is an autoimmune disorder that involves infiltration of eosinophils in the bowel wall of the stomach and/or intestine, resulting in various gastrointestinal symptoms. The majority of cases are diagnosed by findings of increased eosinophils on mucosal biopsies. We describe a rare type of eosinophilic gastroenteritis with eosinophilic infiltration involving only the muscularis propria layer. This elusive diagnosis was made after a full-thickness intestinal wall biopsy. This predominantly muscular type eosinophilic gastroenteritis can cause intestinal obstruction or perforation. Similar to the predominantly mucosal type eosinophilic gastroenteritis, this type of eosinophilic gastroenteritis responds to low-dose or topical corticosteroids.
- Unusual cause of colonic mucosal ulceration and gastrointestinal bleedingKim, Youseung; Kesar, Varun; LeBel, David (BMJ, 2021-06-14)
