Spontaneous Passage of a Dislocated Esophageal Metal Stent: Report of Two Cases

Abstract

Delayed transpyloric impaction is a very rare complication of esophageal metallic stent placement. Authors report different endoscopic removal techniques, but none of these has been validated yet because of their variable success, time-consuming nature, and risk of perforation and hemorrhage. We report that a "wait-and-see" approach is a safe and effective policy in patients with permeable transpyloric impacted esophageal stents.

Complications of stent placement for benign stricture of gastrointestinal tract

“…The displaced stents were extracted under gastroscope guidance. The incidence of stent displacement in our series (3.6%) was in the range as reported previously (0-12.5%) [39][40][41][42] . The incidence of food-bolus obstruction reported in other countries ranged from 7% to 20%…”

Causes and Treatment of Recurrent Dysphagia after Self-Expanding Metal Stent Placement for Palliation of Esophageal Carcinoma

“…We would endorse the recommendation made by others that stent retrieval from the stomach is probably only indicated in the minority of patients in whom a migrated stent causes pain or obstruction of the pylorus, or if it hampers successful placement of a second stent. Perforation or obstruction of the digestive tract are uncommon complications of stent migration [11,18].…”

Endoscopic management and prevention of migrated esophageal stents

“…Three patients eliminated the stent through the rectum, one underwent surgery for stent impaction in the colon, and in nine patients, the stents remained in the stomach without clinical complications (range, 1.8-6.5 mo). Di Fiore et al [16] described two cases of stent impaction in the duodenum that could not be resolved by endoscopy. The stents were left in place and the patients died of metastatic disease 2 and 10 mo later, respectively.…”
