Abstract

Esophagectomy with extended lymphadenectomy and gastric conduit reconstruction is a radical procedure for the treatment of esophageal cancer that is associated with a high morbidity rate. Gastric conduit necrosis is a fatal complication that occurs in 2% of patients. Conventionally, two-stage salvage surgery consisting of removal of the necrotic gastric conduit followed by reconstruction has been performed; however, this procedure has a high morbidity rate. We describe a 61-year-old man who underwent minimally invasive esophagectomy complicated by slowly progressive gastric conduit necrosis associated with complete neck drainage and a stable overall condition. There was a 2 cm gap in the anastomosis. Because there was no evidence of residual gastric conduit necrosis, a removable, covered self-expanding metal stent (SEMS) was inserted to bridge the anastomosis. The stent was fixed to the patient’s ear with silk thread through the lasso on its proximal end to prevent migration. Eight weeks after insertion, the stent was removed easily without any associated complications. The anastomotic defect was completely bridged with granulation tissue, showing progressive epithelialization without leakage or stenosis. The patient was discharged home in good general health. This is the first report of the successful conservative management of esophago-gastric conduit anastomosis disruption with SEMS placement.

Core tip: Gastric conduit necrosis is a fatal complication after esophagectomy. Conventionally, two-stage salvage surgery consisting of removal of the necrotic gastric conduit followed by reconstruction has been performed, but it has a high morbidity rate. On the other hand, a covered self-expanding metal stent (SEMS) has been reported to be effective for the treatment of anastomotic leakage. This is the first report of the successful conservative management of gastric conduit necrosis with SEMS placement. This case highlights the diagnosis and evaluation of the state of esophago-gastric conduit anastomosis disruption and demonstrates that a conservative approach with no surgery could result in a successful outcome.
