nutritional deficits, weight loss
REFLUX ESOPHAGITIS, GASTRIC DILATATION, COMPLICATIONS
Laparoscopic re-LSG is feasible and safe with satisfactory outcomes in patients with weight regain after LSG who have gastric dilatation without reflux esophagitis. Both BLSG and NBLSG had comparable significant weight loss effects when performed as re-LSG operations with a comparable improvement of associated medical problems. The BLSG tends to have a more stable weight loss after two years with a significantly lower BMI, lower stomach volume, and less weight regain. Food tolerance was decreased in both groups but more reduced in the BLSG group. After a 2-year follow-up, both procedures were considered safe, with no significant differences in the occurrence of complications and nutritional deficits.
