Abstract Background Gastroparesis is a syndrome characterized by delayed gastric emptying with associated symptoms. It was reported that the symptoms of diabetic gastroparesis had been greatly improved by transpyloric stent placement. However, the use of stents in benign conditions is considered to be contraindicated because of the increasing risk of complications, such as stent migration, reflux, perforation, bleeding, and, most importantly, new strictures caused by stent-induced tissue hyperplasia. While temporary placement of a self-expanding metallic stent (SEMC) can drastically reduce the risk of complications, few reports are available on the treatment of refractory PSG by temporary transpyloric stent. Does it have a long-term clinical effect after the stent being retrieved? Case presentation After accepting partial resection of the lesser curvature in another hospital, a patient developed refractory gastroparesis. The symptoms hadn’t been improved after long-term drug therapy and balloon dilation therapy. Four months after surgery, a fully covered SEMC was placed by endoscopy in our hospital. Gastroparesis had been greatly improved. Two weeks later, the transpyloric stent was retrieved and the patient didn’t show recurrent symptoms. Follow-ups were arranged at 3 months, 6 months and 1 year respectively, and there was no evidence of recurrence was found. Conclusions This case indicates that temporary transpyloric SEMC is a safe, effective and less invasive alternative for post-surgical gastroparesis patients.
