Abstract

PURPOSE
For most surgeons, colon interposition after gastrectomy remains an infrequently performed procedure because of its complexity. The aim of this study was to assess its technical feasibility and safety as a post-gastrectomy reconstruction method by reviewing our experience with colon interposition.
MATERIALS AND METHODS
From March 2001 to February 2002, 30 colon interpositions after- gastrectomy were done with using the ileo-ascending or transverse colon. We analyzed the clinicopathologic features and the surgical outcomes.
RESULTS
There were 16 males and 14 females in this study with a mean age of 67.5 years (range: 31 to 76 years). Twenty-five ascending colons and 5 transverse colons were used for the interposition, respectively. The mean operation time was 373 minutes (range: 204 to 600 minutes). There were 9 operative morbidities (30%) and 1 operative mortality. The restoration of bowel motility was noted at 3.8 postoperative days; a soft diet was started at 4.9 postoperative days and the duration of the hospital stay was 18.2 days. The percentage of weight loss in the patients with total, proximal and distal gastrectomy was 16.3%, 14.0% and 8.8%, respectively, at 6 months, and thereafter the weight loss gradually recovered as 8.1%, 7.5% and 5.6%, respectively, at 5 years postoperatively. Gastric stasis was the one of the most meaningful long-term complications, and especially in the patients who underwent distal gastrectomy with colon interposition.
CONCLUSION
Colon interposition after gastrectomy was a very complex procedure with a long operating time and many anastomosis sites. The postoperative outcomes failed to achieve satisfactory weight gain and the patients displayed postprandial symptoms. This suggested that this procedure was not an appropriate procedure for conventional reconstruction after gastrectomy.
