Obesity is a chronic metabolic disease driven by multiple factors such as genetic susceptibility, environmental factors, and neuroendocrine system disorders. In recent years, the prevalence of obesity in China has been increasing year by year, and a series of obesity-induced diseases are a serious threat to public health. Glucagon-like peptide-1 receptor agonists, as a representative of the new weight loss drugs, have shown a therapeutic effect close to that of weight-loss metabolic surgery in clinical trials by targeting central appetite and metabolism and other synergistic effects, but they still face key problems such as significant differences in individual efficacy, limited evidence of the safety of long-term treatment, and regaining body weight after discontinuation of the drug. The mechanism of action and clinical evidence of several obesity drugs approved and listed in China are summarized, and the progress and challenges of obesity drug therapy in China in combination with recent advances in the development of multi-target agents internationally are discussed, with a view to providing a scientific basis for the clinical drug management of obesity and providing ideas for the research and development of obesity drugs in China as well as for the clinical transformation.
Objective To investigate the operating skills for treatment of morbidly obese patients with gallstone by using laparoscopic technique meanwhile. Methods From Oct.2006 to Nov.2009, 178 morbidly obese patients undergoing laparoscopic adjustable gastric banding （LAGB）, in which 18 cases combined with gallstone underwent laparoscopic cholecystectomy （LC） meanwhile. Results All of 18 morbidly obese patients with gallstone underwent LAGB and LC successfully, the operating time was (126±24) min and bleeding volume was (50±16) ml. No serious infectious complications occurred, but 3 cases with low-grade nausea and vomiting, 2 cases with adipose tissue liquefaction in incision, and one case with few seroperitoneun， all were cured conservatively. Conclusion Morbidly obese patients with gallstone undergoing LAGB and LC at the same time by changing site of incision is a safe and effective procedure and a feasible technique.
Laparoscopic sleeve gastrectomy (LSG) is an effective and lasting method for treating obesity, type 2 diabetes and other obesity related metabolic diseases. The symmetrical three-port LSG has been proven to be a simple, safe, and effective surgical procedure. However, China still lacks standardized surgical operation guidelines for this method. This guideline provides a detailed description of the various steps and key details of the symmetrical three-port LSG, aiming to standardize and normalize the symmetrical three-port LSG in the bariatric and metabolic field in China, and to provide standardized surgical procedures for clinical surgeons in this field.
ObjectiveTo explore the effect of laparoscopic sleeve gastrectomy (LSG) on obesity and its comorbidities.MethodThe literatures about LSG in the treatment of obesity and its comorbidities were collected and summarized.ResultsLSG could not only effectively reduce the weight of patients with obesity, but also obviously alleviate comorbidities related to obesity, such as type 2 diabetes mellitus, obstructive sleep apnea syndrome, polycystic ovary syndrome, essential hypertension, hyperlipidemia, and so on.ConclusionsLSG has a definite and effective long-term weight loss effect, which is equal to other common weight loss methods. It has been recognized by more and more patients and clinicians because it has advantages of simple operation, safety, high efficiency and fewer complications. However, therapeutic effects of some comorbidities, such as gastroesophageal reflux disease, are still controversial and need further tobe studied.
Objective To investigate the clinical application value of unsymmetrical four-port laparoscopic sleeve gastrectomy (LSG). Methods The clinical data of 114 patients with obesity who were admitted to Mianyang Central Hospital from June 2021 to May 2022 were retrospective analyzed. All the 114 patients underwent unsymme-trical four-port LSG, and were observed their surgical and postoperative conditions, complications and follow-up the patient’s esthetic satisfaction of wounds at 3 months after surgery. Results All 114 patients underwent unsymmetrical four-port LSG successfully, without conversion to open surgery. The operative time was 68–160 min, average (104.2±26.1) minutes; volume of intraoperative blood loss was 2–50 mL, average (10.7±7.6) mL; the duration of postoperative hospital stay was 3–6 d, average (4.0±0.7) days. Of the 114 patients, 8 patients (7.0%) had fat liquefaction of wounds, 68 patients (59.6%) had postoperative nausea and vomiting in the 24 hours after operation, and all patients had no serious complications such as gastrointestinal bleeding, intraperitoneal hemorrhage, or gastric leakage. One hundred and fourteen patients were followed-up for 3–14 months, with a median follow-up of 6 months. Forty patients (35.1%) had hair loss, 3 patients (2.6%) had mild anemia. Of the 114 patients, 2 (1.8%) were dissatisfied with the cosmetic effects of wounds, 64 (56.1%) were satisfied, and 48 (42.1%) were very satisfied. The satisfaction rate was 98.2% (112/114). Conclusion The unsymmetrical four-port LSG is safe and feasible, it does not affect esthetic satisfaction of wounds.
ObjectiveTo investigate the short-term effect of laparoscopic sleeve gastrectomy (LSG) in treatment of obesity in China. MethodsLiteratures about the effect of LSG in treatment of obesity were searched from WanFang, CNKI, PubMed, and Web of Science, then these literatures were filtered according to the inclusive and exclusive criteria and evaluated. Meta analysis was performed based on data extracted from these literatures. ResultsThree hundreds and eighty three cases of LSG were retrieved from 12 literatures. Compared with the preoperative, the body mass index (BMI) was lower in 6 months after LSG (MD=7.56, 95% CI: 5.77-9.34, P < 0.000 01), and compared with 6 months after LSG, the BMI was lower in 12 months after LSG (MD=3.19, 95% CI: 2.20-4.18, P < 0.000 01). Compared with 1 months after LSG, the excess weight loss (EWL%) was higher in 6 months after LSG (MD=-42.77, 95% CI:-45.77--39.77, P < 0.000 01), and compared with 6 months after LSG, EWL% was higher in 12 months after LSG (MD=-19.71, 95% CI:-25.54--13.87, P < 0.000 01). After the LSG, BMI decreased, but EWL% increased over time. ConclusionsIn China, LSG has obviously short-term curative effect in the treatment of obesity.
A lot of evidence-based medical evidence has shown that laparoscopic Roux-en-Y gastric bypass (LRYGB) is a durable and effective method for obesity and diabetes, and can significantly improve a series of obesity-related metabolic complications. This guideline provides a detailed description of the main operating steps and technical points of the symmetric three-port LRYGB, including posture layout, trocar position selection, liver suspension, gauze exposure, production of small gastric sacs, gastrojejunal anastomosis and production of biliary pancreatic branches, entero-enteric side to side anastomosis, closure of gastrointestinal anastomosis and mesenteric hiatus, greater omentum coverage, and closure of incisions. The purpose is to standardize the operating process of the symmetrical three hole method of LRYGB, providing standardized surgical operation references for clinical doctors in the field of obesity metabolic surgery.
ObjectiveTo systematically review the clinical effects of green tea extracts on simple obesity. MethodsSystematic retrieval were conducted in PubMed, The Cochrane Library (Issue 8, 2012), CNKI, VIP, CBM, and WanFang Data to collect the randomized controlled trials (RCTs) on green tea extracts in treating patients with simple obesity. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed the methodological quality of the included studies. Meta-analysis was then performed using RevMan 5.0. ResultsA total of 11 RCTs involving 693 patients were included. Results of meta-analysis displayed that compared with the control group, patients in the green tea extracts group significantly had a obvious decrease of body mass (WMD=-0.32, 95%CI-0.46 to-0.17, P < 0.000 1) as well as body mass index (BMI) (WMD=-0.07, 90%CI-0.09 to-0.05, P < 0.000 01) with significant differences. ConclusionCurrent evidence shows that, green tea extracts could effectively treat simple obesity.

ObjectiveTo explore the necessity of staple-line reinforcement (SLR) during laparoscopic sleeve gastrectomy (LSG) through evaluating its potential benefit and safety. MethodsA historical cohort study was conducted in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. The consecutive patients underwent LSG for morbid obesity by the same operative team from June 2022 to August 2023 were included, which were assigned into SLR group and un-SLR group according to the SLR or not. Both groups were assessed in terms of the operating time, postoperative hospital stay, total hospital stay, surgical costs, and complications. ResultsA total of 87 patients underwent the LSG from June 2022 to August 2023, all of whom were successfully completed without any conversion to open surgery. Among them, there were 34 cases in the SLR group and 53 cases in the un-SLR group. There were no statistical differences in the age, gender, body mass index, and so on between the two groups (P>0.05). There were no postoperative complications such as gastric leakage, bleeding, or gastrointestinal stenosis, and no perioperative death, as well as no case of reoperation within 30 d after surgery in all patients of the two groups. And there were no statistical differences in the postoperative hospital stay and total hospital stay between the two groups (P>0.05). However, it was found that the operative time was shorter (P<0.05), the surgical costs and total hospital stay costs were also less (P<0.05) in the un-SLR group as compared with the SLR group. ConclusionsBased on the analysis of cases data in this study, there is no added benefit in terms of reducing staple-line leak, bleeding, etc. in adopting SLR during LSG, and the operating time is prolonged and the cost is increased. So the necessity of the SLR or not during LSG needs to be further researched.
