Colonic interposition, a contemporary experience: technical aspects and outcomes.

Colonic interposition is rarely used as an oesophageal replacement after resection, as the preferred use of stomach involves less anastomoses and lower risks of major complications. The functional outcome from the colonic conduit is also unpredictable. This report documents the spectrum of experience of a high-volume oesophageal centre, highlighting indications, techniques and functional outcomes. A retrospective review was undertaken of a prospective database from 2012 to 2016. Four of 252 (1.5%) cases in this time period utilised colon interposition. Two cases were for gastric conduit necrosis following oesophageal cancer resections, one for caustic ingestion with both an oesophago-bronchial fistula and gastric injury, and one for a primary oesophageal malignancy in a patient whom previously had a total gastrectomy. All patients had either a retrosternal or posterior mediastinal isoperistaltic right colon conduit placed. Two of three cancer patients are alive and disease free at 3 and 5 years, respectively. Surviving patients are weight stable and tolerating a normal diet. Both report excellent quality of life using validated assessment tools. Colonic interposition is rarely required in modern oesophageal practice, but with this technique good long-term nutritional and functional outcomes can be obtained. It is required in the armamentarium of a specialist centre, and training given its rarity may require novel approaches such as simulation and cadaveric-based training.
