The aim of the study was to evaluate the results of laparoscopic adjustable gastric banding (LAGB) in patients lost to follow-up.
Patients lost to follow-up were identified from a consecutive cohort of 495 patients who underwent LAGB between November 1995 and September 2006. These patients were asked to return to follow-up and their actual weight was assessed.
Of 93 patients lost to follow-up, 73 were motivated to reattend. Of these, 60 per cent (44 patients) had lost less than 25 per cent of excess weight, compared with 16.3 per cent (P < 0.001), 27.0 per cent (P < 0.001) and 42 per cent (P = 0.026) of patients after 2, 4 and 8 years of regular follow-up.
Patients lost to follow-up are more likely to have poor weight loss, emphasizing the importance of follow-up after LAGB. Outcome after surgery for morbid obesity should include patients lost to follow-up as a measure of overall success.
本研究旨在评估腹腔镜可调节胃束带术（LAGB）治疗随访丢失患者的结果。
从 1995 年 11 月至 2006 年 9 月连续收治的 495 例 LAGB 患者中确定随访丢失的患者。这些患者被要求返回接受随访，并评估其实际体重。
在随访丢失的 93 名患者中，有 73 名有动力重新就诊。其中，60%（44 名患者）的患者体重减轻不到 25%，而在 2、4 和 8 年定期随访后，这一比例分别为 16.3%（P<0.001）、27.0%（P<0.001）和 42%（P=0.026）。
随访丢失的患者体重减轻的可能性较小，这强调了 LAGB 术后随访的重要性。病态肥胖症手术后的结果应包括随访丢失的患者，作为整体成功的衡量标准。
