AbstractTrekkers going to high altitude can suffer from several ailments both during and after their treks. Gastro-intestinal symptoms including nausea, vomiting, and abdominal pain are common in high altitude areas of Nepal due to acute mountain sickness or due to a gastro-intestinal illness. Occasionally, complications of common conditions manifest at high altitude and delay in diagnosis could be catastrophic for the patient presenting with these symptoms. We present two rare cases of duodenal and gastric perforations in trekkers who were evacuated from the Everest trekking region. Both of them had to undergo emergency laparotomy and repair of the perforation using modified Graham's patch in the first case and distal gastrectomy that included the perforated site, followed by two-layer end-to-side gastrojejunostomy and two-layer side-to-side jejunostomy in the second case. Perforation peritonitis at high-altitude, though rare, can be life threatening. Timely evacuation from high altitude, proper diagnosis and prompt treatment are essential for taking care of such patients. Keywords: duodenal ulcer; Everest; hypoxia; mountaineering; trekking.
