[Reinterventions for complication and defect of coloesophagoplasty]

To report a series of 17 patients operated for a complication oesophagocoloplasty, with evaluation of therapeutic modalities, and both early and distant results.

From 1985 to 2003, 17 patients with a mean age of 50 years (range: 23-76) were reoperated after coloplasty pediculated on left superior colic vessels. Initial diseases were caustic ingestion (N=7), cancer (N=6), oesophageal perforation (N=2), gastric lymphoma (N=1) and oesotracheal fistula (N=1). Coloplasty has been performed as a first-intent procedure in 13 cases and as a second-intent procedure after failure of a previous operation in 4 cases. Nine patients were initially operated in another center and were subsequently referred in our unit. Complications needing reoperation were graft necrosis in 8 cases (47%) and stricture in 9 cases (53%). All patients with necrosis were reoperated within the 10 first postoperative days.

Necroses were treated by complete (N=5) or partial (N=3) resection of the coloplasty. Strictures were treated by resection-reanastomosis (N=3), right ileocoloplasty (N=2), colic stricturoplasty (N=2), a free antebrachial flap (N=1) and a tubulized latissimus dorsi myocutaneous pedicled flap (N=1). The 30-day mortality rate was 12% (N=2) and the overall morbidity rate was 66%. All deaths occurred after reoperation for necrosis. Eleven patients (65%) kept or recovered digestive continuity (including the 9 with stenosis) and 8 (73%) eat normally. Four patients with transplant necrosis died before reestablishment. Four patients operated for necrosis died before restoration of digestive continuity and 2 patients are still awaiting restoration.

Use of colon as an oesophageal substitute is risky. Reoperations for stenosis allows satisfactory oral feeding, while reoperation for necrosis is associated with both high early mortality and a low rate of restoration or digestive continuity. This later requires a range of complex surgical procedures.
