Endoscopic Cystogastrostomy has many complications like bleeding, infection, migration of stent, perforation etc. We report a case of a young male, who had unexpected complication of stent migration postcystogastrostomy, into the duodenum, which re-entered stomach, perforating the wall of antrum. Though this case could be managed conservatively, such complication may lead to fatal consequences such as perforation peritonitis .Thus this case report can be considered as a reference, that such an unexpected complication might occur while performing endoscopic cystogastrostomy.
