This highlights the importance of early recognition and intervention to prevent severe complications such as oesophageal perforation. Endoscopic assessment and surgical intervention remain the cornerstone of the management, tailored to the clinical severity and surgeon’s expertise. The prognosis largely depends on the timeliness of diagnosis and intervention, with early treatment typically resulting in favourable outcomes.  \nKeywords: gastroesophageal intussusception; abdominal pain; achalasia; myotomy.  \nINTRODUCTION  \nGastroesophageal intussusception (GEI) is an uncommon condition in adults, characterized by invagination of the stomach into the oesophagus. Its clinical presentation is often nonspecific, with symptoms ranging from dysphagia, vomiting to epigastric or chest pain; this makes timely diagnosis challenging. Although most intussusceptions in adults involve the small bowel, GEI isan extremely rare subtype and is often associated with underlying structural abnormalities of the gastroesophageal junction, such as achalasia.1–4 Peroral endoscopic myotomy (POEM) has emerged as an effective minimally invasive treatment for achalasia; however, anatomical and functional alterations following POEM may predispose a subset of patients to post-procedural complications. After consent, we report a rare case of acute retrograde GEI occurring after POEM for type II achalasia, with swollen gastric mucosa and impending ischaemia that necessitated urgent surgical intervention. This case highlights the importance of maintaining a high index of suspicion for GEI inpatients presenting with acute obstructive symptoms following oesophageal motility procedures.  \nCASE SUMMARY  \nA 43-year-old male with a history of achalasia treated with balloon dilatation, POEM, and jejunostomy tube presented to a community hospital with a 2-week history of nonspecific upper abdominal pain, worsening over the preceding day, and haematemesis. He denied melena, and his last bowel movement was one day prior to presentation. There were no additional systemic or gastrointestinal symptoms.  \nOn arrival, he was tachycardic (HR 110–120 bpm), hypotensive (BP 90/50 mmHg), afebrile, and maintaining oxygen saturation >92% on room air. Abdominal examination revealed a soft, tender, non-distended abdomen. Laboratory investigations showed leucocytosis (WBC 43 × 109/l), haemoglobin 145 g/l (baseline 90 s), creatinine 503 µmol/l, and lactate 3.7 mmol/l.  \nHe was resuscitated with intravenous (IV) fluids, started on IV pantoprazole and broad-spectrum antibiotics, and a Foley catheter was placed for urine output monitoring. Chest X-ray showed no pneumoperitoneum. A contrast-free computed tomography (CT) scan revealed a diffusely distended oesophagus wi","cbCaiiNhP6d3O1T0","https://ap.wps.com/l/cbCaiiNhP6d3O1T0","pdf",1231457,"English","# Abstract\n# Introduction\n# Case Summary","[{\"question\":\"What is gastroesophageal intussusception and why is it clinically significant?\",\"answer\":\"Gastroesophageal intussusception is a rare condition where the stomach invaginates into the oesophagus.
