Introduction: Laparoscopic sleeve gastrectomy (LSG) is an established bariatric procedure.
Aim: We present our long-term results regarding weight loss and comorbidities during 9 years.
Material and methods: We calculated the percent excess weight loss (%EWL) and changes in body mass index (ΔBMI). We evaluated arterial hypertension (AHT), type 2 diabetes (T2DM) and obstructive sleep apnea syndrome (OSAS).
Results: One hundred seventy-nine patients were included (136 female/43 male), mean age of 40.47 ±11.08 years, median preoperative body mass index (BMI) of 42.93 kg/m2. Median follow-up period was 72 months (36-84 months). The %EWL during follow-up was 41.8 (n = 179 patients, at 3-month follow-up), 64.1 (n = 163), 75.33 (n = 134), 77.1 (n = 103), 76,03 (n = 99), 73.78 (n = 64), 71.58 (n = 37), 63.83 (n = 22) and 64.1 (n = 14) at 6, 12, 18, 24, 36, 48, 60 and 72 months, respectively. We noted a negative correlation between %EWL and both the age and initial weight and BMI of the patient; a negative correlation between gender (male patients) and %EWL was also found. After LSG, 68.2% of patients with AHT presented resolution (no medication) or significant improvement (doses reduced) of the disease. As regards T2DM, 65.8% described resolution or significant improvement after surgery. Furthermore, 31 (70.4%) patients with preoperative OSAS reported resolution/improvement within a year from surgery.
Conclusions: Laparoscopic sleeve gastrectomy is a safe and effective procedure, with good results in the short and medium term. Long-term follow-up reveals a tendency to weight regain after approximately 2 years from primary surgery, with the need for revisional surgery in some cases.
Keywords: laparoscopic sleeve gastrectomy; long-term follow-up; weight regain.
