Patient Reported Outcomes of a "Tailored" Bilio-Pancreatic Limb Length on Mean Weight Loss and Mean Daily Dietary Food Choices in the One Anastomosis Gastric Bypass (Mini-Gastric Bypass-Original Technique)

Bariatric surgery (BS) has a history of new procedures and techniques arising and then disappearing due to problems and complications. The present is no different with new and old procedures changing with the regularity of night following day.

One of the important questions today in BS is the length and or need/value of the Biliopancreatic limb bypass (BPLL.) The Sleeve and the Band have "0" bypass, the RNY has a "short" bypass and the Biliopancreatic Diversion type procedures have a "long" (distal) bypass.

The Mini-Gastric Bypass Original Technique (MGB-OT) version of the One Anastomosis Bypass (OAGB) includes a "medium" length of bypass, longer than the BPLL of the RNY and shorter than the the "Long" BPL of the BPD procedures. In addition, uniquely, the MGB-OT includes a "Tailored" BPLL.

Not all OAGB surgeons use this approach and several have argued in favor of a "Fixed" BPLL of 150 cm.

This paper is part of a series of studies of the "Tailored" BPLL specifically in MGB-OT patients.

Notably it demonstrates in an online survey that patient reported weight loss and food choices change after MGB-OT and in addition the changes are related to the "Tailored" BPLL
