Roux-en-Y augmented gastric advancement: An alternative technique for concurrent esophageal and pyloric stenosis secondary to corrosive intake

Table 1 Predicted potential comparison of the two techniques for esophageal replacement

	Colonic interposition	Roux-en-Y augmented gastric advancement
Vascular supply and conduit necrosis rates	Good; conduit necrosis rate 2.4%-18%	Potentially excellent; conduit necrosis rate 2%-5%
Mild mucosal ischemia	Ischemic colitis (3%)	Gastric erosions
Gastroesophageal and colo-esophageal reflux rates	Low (4%-5%)	Low
Conduit reservoir capacity	Acceptable	Better
Postprandial conduit fullness	Less	More
Probability of cervical esophageal anastomotic leakage rate	Low	Low
Probability of postoperative esophageal anastomotic stricture formation	Low	Higher
Potential complications	Higher probability of anastomotic leakage in colonic anastomosis	Higher probability of gastric erosions postoperatively due to retention gastritis
