BACKGROUND: Roux-en-Y gastric bypass (RYGB) has been considered as the most efficient method in bariatric surgery.
Indeed, Laparoscopic Sleeve Gastrectomy (LSG) which is easier to do, has been increasingly used in the recent years. The
aim of the present study was to compare short-and mid-term outcomes of RYGB and LSG.
METHODS: Medical records of 62 patients who underwent either RYGB (GroupR) or LSG (GroupL) in our General
Surgery Department between 2010 and 2013 were retrospectively reviewed. Demographics, comorbidities, preoperative
laboratory values, length of hospital stay and postoperative complications were recorded. During follow-up in the postoperative
period, body-mass-index (BMI), excess weight loss (EWL), triglyceride levels (TG), and low-density lipoprotein
(LDL) levels were recorded at the 1st, 3rd, 6th, and 12th months.
RESULTS: Mean length of hospital stay was significantly higher in GroupR (p = 0.001), which was also correlated with
BMI. EWL at 1st, 3rd, 6th, and 12th months was significantly higher in GroupR. Hair loss was significantly higher
in GroupR (p < 0.05). The rates of diabetes mellitus and hypertension in the preoperative period and at 6th and 12th months did not significantly differ between the groups. Preoperative TG and LDL values were significantly higher in GroupR (p < 0.05). CONCLUS ONS: This study indicated, that RYGB is statistically more effective than LSG, but LSG has clinically almost the same effect as RYGB, and also hospital stay, postoperative complications as hair loss are decreased in LSG.
