Abstract

Background: Surgery for morbid obesity causes a significant, sustained weight loss that lowers obesity-related morbidity and improves survival as compared to those getting optimal medical treatment.

Long-term SG outcomes with over 10 years of follow-up have recently become available, and they show that those who come with weight loss failure (WLF) due to insufficient weight loss (IWL) or weight regain (WR) and/or complications like gastroesophageal reflux disease (GERD).

So, revisional surgery following SG is becoming more prevalent for bariatric surgeons. Following a failed sleeve gastrectomy, LMGB was recently used as a complementary procedure; this study aimed to examine the viability, mortality, morbidity, and short-term weight loss outcomes of laparoscopic mini gastric bypass when used as an additional malabsorptive procedure for those who underwent SG but experienced insufficient weight loss or weight regain.

Patients and method: A prospective observational study comprised of 20 patients with weight loss failure either due to insufficient weight loss or weight regain following LSG.

Between December 2021 and December 2022, laparoscopic mini-gastric bypass procedures were conducted at Al-Azhar University Hospitals' surgical department in Cairo, Egypt, along with 1 year of postsurgical patient follow-up.

Results and conclusion: The mini-gastric bypass operation contributed to significant weight loss, with a mean BMI of 53.66 kg/m2 before the revision and 33.86 kg/m2 one year following the revision, and it also contributed to a clear improvement in some diseases related to patients with obesity, like type 2 diabetes by 75% and hypertension by 50%.
