3. FIRST INTERNATIONAL CONSENSUS
CONFERENCE
MINI-GASTRIC BYPASS /
ONE ANASTOMOSIS BYPASS
PARIS 2012

4. Introduction
• The Mini-Gastric Bypass /
One Anastomosis Bypass (MGB)
is gaining international recognition.

5. Introduction
• In October 2012
• 50 surgeons from around the world met in
Paris for the
• First International Consensus Conference
on the MGB/OAB.
• Producing a consensus document on
• Results and
• Important technical performance issues

6. Purpose
• The purpose of this paper is to report
on the results of the survey and
discussions on the technical issues in
performance of the MGB.

7. Methods:
• In Addition to Consensus Conference
• Surgeons were canvassed
from around the world.

8. Results
• Replies were obtained from
• 29 countries,
• 6 continents,
• 49 surgeons attended the Paris
conference and
• 112 surgeons completed survey.

9. 49 Surgeons from 29 Countries

10. Results
• Two methods of performing the
MGB/OAB,
• One Anastomosis Gastric Bypass Anti-
reflux Technique of Garcia-Caballero /
Carbajo (OAGB) or the
• “Mini-Gastric Bypass” technique

11. Surgical Technique
• 27% used the OAGB technique and
• 68% used the “MGB technique of
Rutledge.“
• Other Modified
Rutledge/OA
techniques

12. Results
• Intraoperative methylene blue test
performed in 86.4%,
• intraoperative "Air Inflation" test used
always by 29.2%,
• Postoperative NG tube 20.8%,

13. Results
• Post Op Drains;
• 2 drains, Always 12.5%,
• 1 drain, Always 54.2%.
• Postop UGI:
• Always 33.3%;
• Almost Never 25%;
• Never 25%

14. Results
• Average # of MGB/OAB surgeon’s cases last

• Average bougie size 35f+3,
• # ports used 5,
• Mean length of pouch (cm) 19+4,
• Length of bypass (cm) 197+20,
• Op time (minutes) 73+15,
• Blood loss (ml) 51+11,
• Hospital stay (d) 3.4+4.

15. Results
• Results reported to be excellent:
• Resolution of Diabetes 79%,
• Excess weight loss 76%,
(Three reported 100% +/- EWL)
• Weight Loss "Failure" 3% and
• 81% Lost More than 50% of EW.

16. Conclusions:
• The MGB/OAB is gaining worldwide use
and recognition.
• The First International Consensus
Conference on MGB / OAB demonstrated
