MORSE STUDY
MORtality Related to Bariatric SurgEry: A TUGS Multinational Audit Brief Audit Protocol
STUDY OBJECTIVES
1) The primary objective is to find out the common causes of early (90-day) and late (>90-day) mortality related to bariatric surgery
​
2) The secondary objective is to find out any learning points that could help us reduce the magnitude of this problem.
INCLUSION CRITERIA
-
All patients who die within 90 days of a primary/ revisional bariatric surgical/ endoscopic procedure between 1st January 2022 and 31st December 2022 at your centre (irrespective of where the initial procedure was performed)
-
All patients who die > 90-days after a primary/ revisional bariatric surgical/ endoscopic procedure (irrespective of the time gap between the two) between 1st January 2022 and 31st December 2022 at your centre, if the bariatric surgery was mentioned anywhere on the death certificate as a primary, secondary, or contributory cause.
-
Adults (>/=18 years)
EXCLUSION CRITERIA
1) Patients who die outside the above dates or who have never had a surgical or endoscopic bariatric procedure.
2) Patients <18 years of age.
3) Patients dying > 90-days after a surgical/endoscopic, primary/ revisional bariatric procedure if bariatric surgery (or name of any bariatric procedure) was not mentioned anywhere on the death certificate.
Abstract
Bariatric surgery is associated with low but definite early and late mortality. This study aims to further understand early (≤ 90 days) and delayed (> 90 days) mortality related to bariatric surgery.
This is a retrospective collaborative audit of patients who had undergone bariatric surgery and developed complications that ultimately led to death.
Individuals who were 18 years or older and had undergone bariatric surgery (primary, revisional, and endoscopic procedures) and subsequently died within 90 days or after 90 days following the surgery between 1 January 2022, and 31 December 2022. A descriptive analysis was conducted. About 30 centres from 21 countries submitted data on 82 patients where patient death was deemed to be related to bariatric surgery.
Mortality within 90 days post-surgery was observed in 58 individuals (70.7%), while 24 patients (29.3%) died after this period.
Causes of mortality after SG include GI leak, PE, respiratory infection, and malnutrition. Causes of mortality after RYGB include GI leak, coronary heart disease, and bleeding.
Reported common causes of early mortality in this study were gastrointestinal leaks, bleeding, coronary heart disease, and pulmonary embolism.
Reported common causes of delayed mortality were gastrointestinal leaks and malnutrition.
This study characterises patients where death was attributed to a bariatric procedure and identifies common causes of death in these patients. This could aid development of strategies for preventing and managing these complications in the future.
