As techniques have been refined, more patients in the United States have undergone bariatric surgery for weight loss. These surgeries alter the gastrointestinal tract to restrict caloric intake. While most surgeons prefer sleeve gastrectomy and Roux-en-Y gastric bypass, some older procedures, like vertical band gastroplasty, have fallen out of favor due to late complications. In any bariatric procedure, endoscopy can be challenging if indicated due to altered anatomy. Here, we present a case of challenging anatomy due to remote vertical band gastroplasty in a patient presenting with cholangitis, highlighting the effective use of a lumen-apposing metal stent across a vertical band stenosis.

Ewing sarcoma (ES) is a rare malignancy that typically occurs within the skeletal system but can also develop extraskeletally. Extraskeletal ES typically presents paraspinally, in the limbs, and retroperitoneum. Rarely, it presents as a primary gastric ES. To our knowledge, there are only 13 reports of primary gastric ES, none of which originated in the cardia of the stomach. Increased identification of how extraskeletal ES, specifically primary gastric ES, presents and characterized is crucial for future treatment development and accurate prognosis. We present the case of a 36-year-old man with hematemesis, ultimately found to have primary gastric ES in the cardia.

Esophageal epidermoid metaplasia (EEM) is a rare condition that has not been described in Stevens-Johnson syndrome (SJS) and has only been described once in pediatrics. Neither the relationship, treatment, nor surveillance between SJS, esophageal strictures, and EEM has been established. We report the first case of EEM in an 8-year-old girl with esophageal stricture after SJS. Pediatric patients presenting with dysphagia after SJS should be evaluated for esophageal stricture and subsequent EEM development. Owing to EEM's, association with esophageal squamous cell cancer, close follow-up, biopsy surveillance for dysplasia, endoscopic treatment, and TP53 genetic sequencing should be considered.

Colonic angiomyolipomas (CA) are very rare benign tumors arising from perivascular epithelioid cells. CA are most often found either during screening colonoscopies or as an incidental finding during abdominal imaging. However, some rare cases of CA are found to present with abdominal pain and hematochezia. In this article, we report a case of a 62-year-old man who presented with intermittent hematochezia and constipation who was found to have an angiomyolipoma in the sigmoid colon. The lesion was successfully removed endoscopically with no recurrence of bleeding and no complications within the first 30 days after the procedure.

Mucinous adenocarcinoma with signet cell features originating from Meckel diverticulum (MD) is an extremely rare primary malignant tumor. A woman in her 30s presented with multiple episodes of vomiting, abdominal pain, and constipation. She had a history of stricturing Crohn's disease and managed well with steroids, azathioprine, and infliximab. This time, a computed tomography scan showed distal ileal small-bowel obstruction. Urgent surgery for a nonsettling small bowel obstruction was performed. MD was incidentally found and was concerning for malignancy. This case report illustrates how this extremely rare malignancy was behaving like Crohn's disease, which delayed the diagnosis and treatment.

Colonic diverticulitis is inflammation of diverticula, which are sac-like protrusions in the colonic wall. It is thought that increased intraluminal pressure and trapped food leads to inflammation. Newer theories suggest that alterations in the gut microbiome and chronic inflammation play a role as well. Diverticulitis commonly affects discrete sections of colon. Acute multifocal diverticulitis is defined as diverticulitis in at least 2 different sites of the colon separated by at least 10 cm, which is very rare. Ideal management is unclear; however, our patient improved with supportive measures and antibiotics without complications of abscess, perforation, or need for surgery.
