The authors undertook this study to compare their modified version of sleeve gastrectomy with conventional sleeve gastrectomy in terms of the severity and incidence of gastroesophageal reflux.

Materials and Methods

This study was conducted for the patients that underwent primary laparoscopic sleeve gastrectomy in a single center from 2011 to 2015. Patients that underwent conventional LSG were allocated to Group A (n=46), and sleeve contouring gastrectomy to Group B (n=45). Postoperatively %EBMIL, PPI use, and endoscopy findings, and receipt of conversion surgery were compared.


Age, gender (F:M), and baseline BMI in groups A and B were 34.2±10.5 years vs. 30.9±8.9 years (P=0.142), 28:18 vs. 30:15 (P=0.565), and 36.8±8.9 kg/m² vs. 35.5±5.8 kg/m² (P=0.046), respectively. %EBMIL values at 1 year postoperatively were not different (P=0.946), mean durations of PPI use were 141.2±240.3 (30–1160) days vs. 71.9±24.3 (60–128) days, respectively (P=0.058). Endoscopic findings at 1 year were LA-M in 22/32 (68.8%) vs 19/24 (79.2%), LA-A in 7/32 (21.9%) vs. 5/24 (20.8%), LA-B in 1/32 (3.1%) vs. 0/24 (0.0%), and LA-C in 2/32 (6.3%) vs. 0/24 (0.0%) (P=0.483). Numbers of patients used PPIs over 1 year were 4/46 (8.77%) vs. 0/45 (0.0%) (P=0.043), and conversions to RYGP were 1/46 (2.21%) vs. 0/45 (0.0%), respectively (P=0.320).


Contouring of the sleeve in LSG in this study might reduce the incidence of de novo GERD without compromising weight loss.
