Efficacy of precision laparoscopic sleeve gastrectomy for the treatment of obesity

Objective To investigate the efficacy of precision laparoscopic sleeve gastrectomy (LSG) for the treatment of obesity.Methods The clinical data of 50 obese patients who received LSG under the guidance of "precise weight loss surgery" at the First Affiliated Hospital of Jinan University from August 2011 to July 2013 were retrospectively analyzed.The body mass index (BMI),complication and metabolic disease remission before and after operation were recorded.Results All the 50 patients successfully underwent LSG.The operation time,blood loss,postoperative duration of hospital stay were (59 ± 10) minutes,(10 ± 4) ml and (5.2 ± 1.1) days.No severe complications were observed.The percentage of excess weight loss (EWL) and decrease of BMI of 23 patients who were followed up for more than 1 year were 80％ ± 18％ and (10.1 ± 3.4)kg/m2,respectively; the percentage of EWL and decrease of BMI of 13 patients who were followed up for 6-12 months were 71％ ± 15％ and (8.6 ± 2.3) kg/m2,respectively ; the percentage of EWL and decrease of BMI of 14 patients who were followed up for 1-6 months were 28％± 12％ and (4.2 ± 1.6)kg/m2,respectively.The condition of 6 patients with insulin resistance was back to normal.Six patients had hepatic adipose infiltration,5 of them had lipid levels decreased,and the change of lipid level was not obvious in the other 1 patient.Four patients had type 2 diabetes mellitus,3 patients did not need therapy,1 patient only needed drug therapy.Three patients had hypertension,and their blood pressure was controlled at the normal level after stop of drug administration.Conclusion The incidence of postoperative complication could be reduced by fine and accurate manipulation and applying the "precision weight loss surgery" in operation.
