BACKGROUND: The purpose of this retrospective study was to investigate the feasibility of colon interposition procedures after esophagectomy with extended lymphadenectomy. METHODS: Between 1990 and 2008, 95 consecutive patients underwent colon interposition after esophagectomy with extended lymphadenectomy for esophageal cancer in our Institution. We reviewed clinical data and long-term survival, and also investigated the association between anastomotic leakage and clinicopathologic findings. RESULTS: We applied three-field lymphadenectomy to 71 patients and two-field to 24 patients, by a right thoracotomy. Ninety-two patients underwent reconstruction by a retrosternal route, and a posterior mediastinal route was applied to only three patients. We performed hand-sewn anastomosis in the neck in all cases. Three patients required microvascular surgery. Sixty-one patients (64%) experienced postoperative morbidity, most commonly pulmonary complications. Anastomotic leakage occurred in 12 patients (13%). No colon conduit necrosis was detected. Overall mortality, including hospital mortality, was 5.3%. Dysphagia (39%) and diarrhea (38%) were common and stricture was low (6%) after discharge. The overall 5-year survival rate was 43%. During the latter period (1998 to 2008), when ileocolon grafts evolved as the primary choice for interposition, the rate of leakage decreased from 17% (1990 to 1997) to 5.4%. No mortality was recorded during the latter period. CONCLUSIONS: Results from this study demonstrate that colon interposition after esophagectomy with extended lymphadenectomy is feasible and can have a favorable outcome.
