Background

Laparoscopic gastric banding (LAGB) Laparoscopic single anastomosis gastric bypass (OAGB) are common surgical procedures used in Israel to aid patients living with obesity.AimOur study aimed to compare the effect of these procedures upon obesity related co-morbidities, mainly Obstructive Sleep Apnea (OSA) and the quality of life of those patients in terms of short- and mid-term outcomes, with an emphasis on post-operative aspects and complications.

Methods

A retrospective cohort study comparing OAGB and LAGB patients in our follow-up clinics over at least 3 years of follow-up. Data were collected from the patients' medical files, as well as op reports and clinic visits. Patients' demographics, weight loss, postoperative complications, and length of stay, as well as their quality of life as measured by the BAROS scale were compared, as well as OSA questionnaires including STOP-BANG.

Results

166 patients were enrolled in the study. Of these 32 (19.3%) underwent a OAGB. There were 113 male patients (68.1%) with a mean age of 43.6 years (+-12.9).There were few differences in demographics due to the different nature of procedures (a day procedure for LAGB and 2-3 days of admission for OAGB). But, both BAROS (4.2+-2.2 for OAGB vs. 3.9+-2.2, p=0.476) and the STOP-BANG showed no significant differences (2.3+-1.6 for OAGB vs. 1.9+-1.4, p=0.149).

Conclusions

OAGB and LAGB give a good answer to OSA in patients suffering from obesity. Both are a safe and effective way to control and alleviate the suffering incurred by obesity and specifically those related to OSA.
