PS01.174: AN EXAMINATION OF OUTCOMES AFTER ANTE-THORACIC ROUTE WITH RIGHT HEMICOLON RECONSTRUCTION AFTER ESOPHAGECTOMY.

Abstract

Abstract Background In our institute, we usually use gastric tube for reconstruction organ after esophagectomy. When we can’t use gastric tube, we use right hemi-colon with ante-thoracic route. Previously, we reconstructed by 1-step after esophagectomy, but from 2012, we have done by 2-step for reduce postoperative complications. Methods We enrolled 15 esophageal cancer patients who underwent esophagectomy and right hemicolon reconstruction between April 2004 and December 2016. Results The average age of 15 patients is 67.3. The reasons of using right hemicolon are as follows; post gastrectomy 13, stomach double cancer 2. The reasons of gastrectomy are as follows; gastric cancer 8, duodenum cancer 1, gastric ulcer 4. The average duration from gastrectomy to esophagectomy is 12.5 year. We reconstructed by 1-step for 5 patients, and after 2012, we reconstructed by 2-step for 10 patients. Anastomotic leakages were found in 2 cases (40.0%) in 1-step reconstruction group, and 3 cases (20.0%) in 2-step reconstruction group. In 1-step reconstruction group, 1 case occurred multiple anastomotic leakages and DIC, and another 1 case was found necrosis of reconstructive colon. In 2-step reconstruction group, we found 1 case of major leakage and 1 case of recurrent nerve paralysis and 2 cases of postoperative pneumonia. However, there were no case of tracheotomy. The incidence of pneumonia did not differ between the two groups. And the term of postoperative oral intake tend to shorter in 2-step reconstruction group (P = 0.06). 2 severe postoperative complications (Clavian-Dindo V or IVa) cases were found in 1-step reconstruction group, on the other hand, 2 cases severe complications (CD IIIa) in 2-step reconstruction group. Conclusion In the case of using right hemicolon as a reconstructive organ, 2-step reconstruction approach is useful and superior from the viewpoints of postoperative complications.
