Objective To formulate an individualized evidence-based treatment for a patient with severe obesity. Methods According to the PICO (patient intervention comparison outcome) principle, the evidence was collected and critically assessed after the clinical issues were put forwarded. The patient’s preference was also taken into account in the decision making process. Results Nine clinical guidelines, eight systematic reviews or meta-analyses and three randomized controlled trials (RCTs) were included. According to the data from the included studies and patient’s special condition, a reasonable surgical treatment regime was made to reduce the weight, relieve all kinds of complications and improve the life quality which were all regarded as the expected target. After one year’s follow-up, the patient’s weight reduced by 20 kg, and some obesity-related co-morbidities such as sleep apnea syndrome and hyperlipoidemia were also improved significantly. Conclusion The laparoscopic adjustable gastric band is an effective operation for severely obese individuals. This procedure can not only achieve weight loss, but also improve some obesity-related co-morbidities.
