Flow chart showing the management of adjustable gastric band (AGB) patients (n=267). The patients in the grey rectangle indicate those who are involved in this study. SL, slippage group; BE, band erosion group; IT, intolerance group; LSG, laparoscopic sleeve gastrectomy; SLi, isolated AGB explantation due to slippage; BEi, isolated AGB explantation due to band erosion; ITi, isolated AGB explantation due to intolerance.

SL, slippage; BE, band erosion; IT, intolerance; BMI, body mass index; ASA, the American Society of Anesthesiologists physical status classification system.
Continuous variables are expressed as mean±standard deviation or n (%) unless otherwise indicated. ‘%EBMIL’ means ‘% excess BMI loss=[(BMI at band implantation−BMI at band explantation)/(BMI at band implantation−23)]×100’. ‘%TWL’ means ‘%Total weight loss=% of weight loss at band explantation compared with weight at band implantation’. ‘I’ means ‘normal healthy patient’. ‘II’ means ‘mild systemic disease [e.g., current smoker, social alcohol drinker, pregnancy, obesity (30<BMI<40), well-controlled diabetes mellitus/hypertension, mild lung disease].
*Time from band implantation to explantation.

SLi, isolated adjustable gastric band (AGB) explantation due to slippage; BEi, isolated AGB explantation due to band erosion; ITi, Isolated AGB explantation due to intolerance; OP, operation time; LOS, postoperative length of hospital stay; Extragastric, laparoscopic extragastric removal; Transgastric, laparoscopic transgastric removal; Endogastric, endoscopic removal.
Values are presented as mean±standard deviation or n (%) unless otherwise indicated.
*Operation time required for band explantation; †Intra-abdominal abscess, re-laparoscopy (n=2), laparotomy (n=1); ‡Septic shock (n=1), hemorrhagic shock (n=1): both required intensive care unit admission; §Antipyretics used for recurrent spiking fever (>38.0℃). ∥Intra-abdominal abscess, percutaneous drainage insertion (n=1).
