Fallback technique with circular stapler prevents anastomotic obstruction after esophagectomy: A case report of surgical approach.

Rationale: While performing esophago-ileal anastomosis after esophagectomy with circular staplers, the mucosal folds of the ileum can complicate stapling and lead to obstruction, especially when the diameter of the circular stapler is equal or greater than that of the small bowel lumen. Patient concerns: A 53-year-old man, presented with complaints of difficulty in swallowing for 2 weeks. Fifteen years previously, he had undergone partial gastrectomy for gastric ulcers. Diagnosis: The endoscopy showed that there was a large ulcer in the middle-third of the esophagus, about 28 to 32 cm from the incisors. Biopsy of the ulcer confirmed esophageal squamous cell carcinoma. Interventions: We performed an esophageal replacement using the right colon with circular staplers, but anastomotic site occurred due to stacking of the mucosa ahead of the stapler. To revise the anastomosis, we inserted the stapler 2 to 3 cm farther into the lumen than the intended site of anastomosis, and then pulled it back and rotated the stapler to complete the anastomosis. Consequently, the obstruction was corrected. Outcomes: With nearly 16 months' follow-up duration until now, the patient has no difficulty swallowing and has twice received chemotherapy, and returned to his normal life relatively. Lessons: In the event of potential anastomotic obstruction due to accumulated mucosa, the stapler fallback technique can be successfully used achieve patent anastomosis.
