Indications and Coverage of Metabolic and Bariatric Surgery: A Worldwide IFSO Survey Comparing Different National Guidelines

INTRODUCTION

Knowing how metabolic and bariatric surgery (MBS) is indicated in different countries is essential information for the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO).

AIM

To analyze the indications for MBS recommended by each of the national societies that comprise the IFSO and how MBS is financed in their countries.

METHODS

All IFSO societies were asked to fill out a survey asking whether they have, and which are their national guidelines, and if MBS is covered by their public health service.

RESULTS

Sixty-three out of the 72 IFSO national societies answered the form (87.5%). Among them, 74.6% have some kind of guidelines regarding indications for MBS. Twenty-two percent are still based on the US National Institute of Health (NIH) 1991 recommendations, 43.5% possess guidelines midway the 1991s and ASMBS/IFSO 2022 ones, and 34% have already adopted the latest ASMBS/IFSO 2022 guidelines. MBS was financially covered in 65% of the countries.

CONCLUSIONS

Most of the IFSO member societies have MBS guidelines. While more than a third of them have already shifted to the most updated ASMBS/IFSO 2022 ones, another significant number of countries are still following the NIH 1991 guidelines or even do not have any at all. Besides, there is a significant number of countries in which surgical treatment is not yet financially covered. More effort is needed to standardize indications worldwide and to influence insurers and health policymakers to increase the coverage of MBS.

5G-assisted telementored surgery

Safe and effective implementation of remote surgery and telementoring can have significant limitations. Fifth-generation (5G) wireless networks could be useful in overcoming these drawbacks. As a proof of concept, the authors present technical and clinical details of two procedures assisted by telementoring using 5G that were also broadcast live. Secure remote access advice.

[Late ischemic stricture following anterior rectal resection]

A considerable incidence of colonic strictures after oncologic low anterior resections has been reported. The present paper describes a colonic stricture 5 years after the surgery, and not related to radiotherapy, that required a challenging differential diagnosis with local recurrence of rectal cancer. The role of endoscopy in the management of this condition is discussed.
