腹腔镜可调节胃束带术减重疗效及高失访率原因分析

Long-term outcomes and cause of high rate of loss to follow-up after laparoscopic adjustable gastric banding in obese patients

目的评估肥胖患者行腹腔镜可调节胃束带术（LAGB）的长期减重疗效，并探讨LAGB术后高失访率的原因。方法回顾性分析2003年6月至2007年6月间在第二军医大学附属长海医院行LAGB术的226例肥胖患者的临床及随访资料。结果随访至2010年6月，125例（55-3％）患者获得随访．随访时间为3-7年，其中115例（92．0％）患者术后体质量下降，60例（48．0％）减去了额外体质量。失访105例（44．7％），失访患者年龄偏轻（P〈0．05）；而性别、体质量和BMI则与失访率无关（均P〉0．05）。结论LAGB术是减重手术中相对简单、安全性极高的一种术式；但其术后随访较繁琐．失访率较高，应加强其术后随访。

Objective To evaluate the long-term outcomes of weight loss and the cause of high rate of loss to follow-up after laparoscopic adjustable gastric banding （LAGB） in obese patients. Methods Clinical and follow-up data of 226 obese patients undergoing LAGB operation in the Changhai Hospital from June 2003 to June 2007 were analyzed retrospectively. Results A total of 125 patients were followed up for 3-7 years. Among these 125 cases, 115 （92.0%） presented weight loss after LAGB, 60（48.0%） presented extra weight loss after LAGB. Another 105 cases（44.7%） were lost to follow-up. Most of patients who were loss to follow-up were younger（P〈0.05）. Gender, weight and BMI were not associated with the rate of loss to follow-up（all P〉0.05）. Conclusions Laparoseopic adjustable gastric band surgery is a relatively simple and safe procedure among the bariatric surgery, but the follow-up protocol is complex and the rate of loss to follow-up is high. Postoperative follow-up should be emphasized.
