Third IFSO Global Registry Report released

The Third IFSO Global Registry Report (2017) has been released. Published by Dendrite Clinical Systems, under the auspices of the IFSO, the publication reports data from more than 40 countries on more than 196,000 operations, including baseline obesity related disease, operation types, operative outcomes and disease status after bariatric surgery.

This latest report includes 196,188 operation records from 42 countries from five continents, and has detailed information on 106,219 gastric bypass operations (54.1% of all the records submitted), 58,885 sleeve gastrectomy procedures (30.0%) and 19,101 gastric banding operations (9.7%). The publication has some interesting county-to-country analysis and notes a wide variation of BMI pre-surgery between different contributor countries, ranging from 36.7kg m2 in Peru to 51.1kgm2 in Egypt (43.1 kgm2). The highest proportions of gastric bypass surgery were reported in Venezuela (100.0%) and Sweden (95.6%), compared with Kuwait (100.0%), Australia (100.0%) and Saudi Arabia (100.0%), who reported the highest rates of sleeve gastrectomy operations.

Prior to surgery, 21.8% of patients were on medication for type 2 diabetes, 31.4% of patients were treated for hypertension, 15.3% of patients were on medication for depression, 20.2% of patients required treatment for musculo-skeletal pain, 20.3% of patients had sleep apnoea and 24.8% of patients had gastro-esophageal reflux disorder.

Other highlights of the report show:

  • 86.7% of patients who had a gastric band inserted were discharged within one day of their operation after gastric bypass n 63.7% of patients were discharged within two days of surgery;
  • 79.4% of sleeve gastrectomy patients went home within three days of their operation n Unsurprisingly, 98.8% of all operations were performed laparoscopically
  • The Obesity Surgery Mortality Risk Score (OSMRS) varied widely by country with Georgia, Hong Kong and Argentina reporting the highest-risk patient populations (OSMRS groups B & C: 88.2%. 75.0% and 62.0% respectively) and Kuwait, Colombia and the Netherlands reporting the least risk patient populations (OSMRS groups B & C: 17.9%, 20.4% and 23.9% respectively).

The Global IFSO Registry Project was headed by Kelvin Higa (United States), Jacques Himpens (Belgium), Richard Welbourn (UK), John Dixon (Australia), Peter Walton (Dendrite Clinical Systems) and Robin Kinsman (Dendrite Clinical Systems).
