Research finds comparable outcomes for 2 completely different weight reduction procedures

Research we observe

Is One Type Of Bariatric Surgery Better Than Another? A study published online by JAMA Surgery on December 9, 2020 wanted to find out. Two of the most common weight loss surgeries – the laparoscopic gastric bypass procedure and a less aggressive procedure called laparoscopic sleeve gastrectomy – were compared to see which had better results in losing weight and improving quality of life.

The authors of the study conducted a randomized study with 240 people between the ages of 18 and 60 years with morbid obesity. One group underwent a gastric bypass procedure, in which the stomach is surgically shrunk onto a small pouch that is attached to the small intestine. The other group underwent a laparoscopic sheath gastrectomy which removed approximately 80% of the stomach and left a narrow, tubular portion. The gastric bypass group had slightly better weight loss results than the sleeve procedure, but both groups saw the same quality of life improvements after the procedure. In the seven years after the procedure, people who received the sleeve procedure lost 47% of their excess weight, but the gastric bypass group lost a little more, an average of 55% of their excess weight. The researchers described the difference as “statistically significant” but not as “clinically relevant”. The results should be discussed with your doctor.
