ABSTRACT
Analysis of the layout and proportion of classic and innovative surgical procedures of bariatric and metabolic surgery throughout the world, the sleeve gastrectomy is beco-ming the most accepted and respected surgical procedure with its increasingly prominent advan-tages, and its operation number has even exceeded the "gold standard" surgery of the roux-en-Y gastric bypass. This trend is even more pronounced in China. With a small number of physicians lacking experience in gastrointestinal surgery and more and more young physicians joining in the field of bariatric and metabolic surgery, operation related complications and the consequences of insufficient perioperative management experience have occurred successively in clinical practice, such as gastrointestinal leakage, bleeding, lumen and anastomotic stenosis, internal hernia and obstruction, venous thromboembolism, etc. Bariatric and metabolic surgery is a branch of gastro-intestinal surgery, and physicians in the field should have the ability to prevent, predict and manage short- and long-term complications after surgery. The authors believe that through the comprehen-sive evaluation of laboratory indexes, patient signs and related examinations, physicians should have the basic qualities of decisively choosing the surgical timing, choosing the right decision-making, and taking effective measures.
ABSTRACT
Objective:To investigate the application value of right minimal invasive three-port technique of laparoscopic sleeve gastrectomy (RMIT-LSG) for the treatment of obesity.Methods:The retrospective and descriptive study was conducted. The clinical data of 66 obesity patients who underwent RMIT-LSG in the Sir Run Run Shaw Hospital of Zhejiang University School of Medicine from January to October 2021 were collected. There were 15 males and 51 females, aged 28.5(range, 16.0?54.0)years. The body mass index (BMI) of the 66 patients was (36.9±4.3)kg/m 2. There were 20 of the 66 patients combined with type 2 diabetes. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or the WeChat to detect postoperative recovery of patients including body mass changing, BMI and complications 6 months after operation. The follow-up was up to December 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All the 66 patients underwent RMIT-LSG successfully, without conversion to laparotomy or changing surgical method. The operation time and the volume of intraoperative blood loss of the 66 patients were (132±22)minutes and (14±8)mL, respectively. (2) Postoperative situations. The time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative initial water intake, time to postoperative initial liquid food intake and duration of postoperative hospital stay of the 66 patients were (15±6)hours, (1.80±0.60)days, (1.00±0.20)days, (2.00±0.20)days and (3.40±0.60)days, respectively. Of the 66 patients, one case underwent post-operative abdominal hemorrhage at postoperative day 1 and received a second surgery for hemostasis. The patient with postoperative abdominal hemorrhage and other 65 patients recovered well without gastroparesis, gastric fistula, abdominal infection and other complication. (3) Follow-up. All the 66 patients were followed up for 6(range, 1?11)months. All the 66 patients completed the postoperative scar photography at postoperative 1 month, and results of scar photography showed concealed scar with good cosmetic effects. Twenty-seven of the 66 patients were followed up for 6 months after operation, with the weight loss, percentage of weight loss and decrease of BMI were (42±7)kg, 34.8%±2.9%, (14.2±1.9)kg/m 2, respectively. None of the 66 patient had innutrition during the follow-up. Conclusion:The RMIT-LSG is safe and feasible for the treatment of obesity, with a good cosmetic effect of the wound.
ABSTRACT
At present, the aging trend of China′s population is intensifying and the number of overweight and obese elderly people is on the rise. The elderly obese is facing the treatment of related metabolic diseases, including cardiovascular disease, hypertension, type 2 diabetes, etc. In addition to life intervention and drug control, bariatric surgery is also one of the effective methods. Bariatric surgery can permanently reduce body mass, improve or alleviate the condition of patients, and prolong life. The authors analyze the indications and contraindications, perioperative manage-ment, surgical methods, surgical safety and effectiveness, and current problems of bariatric surgery for elderly obese patients.
ABSTRACT
Bariatric surgery is effective on obesity, which can significantly improve the metabolic diseases of obesity patients, especially the type 2 diabetes. However, the surgical proce-dures of bariatric and metabolic surgery are still evolving and in progress. One anastomosis gastric bypass (OAGB) is the latest bariatric surgery recognized by the international bariatric and metabolic surgery community. The authors review the relevant literatures at home and abroad, and introduce the development history, surgical skills, clinical efficacy, status quo and adaptability of OAGB.

ABSTRACT
Bariatric surgery is an effective treatment for obesity and the related metabolic diseases. At present, although the jejunoileal bypass is widely used in various types of bariatric surgery, the effect of reconstructed anatomy after the jejunoileal bypass on normal physiological function of obese patients has not been clarified. This leaves some controversy about the recommended limb lengths in jejunoileal bypass. At the same time, there is no consensus on the optimal biliary limb length and alimentary limb length in the standard gastric bypass. Lack of accurate measurement of common limb length and total small bowel length inevitably results in unsatisfactory percentage of excess body weight loss caused by short limb length, or malabsorption and malnutrition caused by long limb length. The authors discussed the effects of different length of biliary limb, alimentary limb and common limb on weight loss, and introduced the preliminary application and prospects of the jejunoileal bypass including measurement of total small bowel length in bariatric surgery.
ABSTRACT
As the incidence of obesity increases globally, treatment strategies of obesity emerge continuously. However, the weight loss effect varies between individuals without explicit explanations. In the recent years, many researchers have revealed regulation mechanisms of central nervous system on eating behavior, proposing that obese individuals exhibit brain functional abnormalities implicated in homeostatic regulation of food intake, central reward and motivation, emotion, memory, and attention system. Therefore, these scholars appeal that treating obesity cannot remain "brainless" . The most effective treatment currently available for obesity is bariatric surgery which lead to excess weight loss of 42%-67% in accompany with changes in brain activity. Functional magnetic resonance imaging showed a decreased activation in the central reward network and increased inhibitory control in the cognitive control system after bariatric surgeries. In this article, the authors introduce the central nervous system regulation of eating and investigate the effects of bariatric surgery on central nervous system.
ABSTRACT
The new technique of single anastomosis duodenal-ileal bypass with sleeve gastrectomy appeared during recent years, which is a modification of biliopancreatic diversion with duodenal switch. The basic principles of this technique are restricted food intake by a sleeve gastrectomy and decreased absorption by the duodenal-ileal anastomosis. The new technique is relatively simple, with less malnutrition, better weight loss and metabolic disorders remission. The principle, surgical technique, results and possible complications are described, and the technique is also compared with existing weight loss operations in this article.
ABSTRACT
Nowadays, the incidence of obesity and related metabolic diseases is increasing around the world, which seriously endangers the human health and the quality of life. Obesity has become the most prominent public health issue in the time. With the rapid development of surgical treatment of obesity combined with type 2 diabetes mellitus, bariatric surgery has gradually evolved into a new important branch of upper gastrointestinal surgery or gastrointestinal surgery, that is bariatric and metabolic surgery. To date, bariatric surgery has entered in China since twenty years ago. Following the steps of the rapid development of bariatric and metabolic surgery in the world, bariatric surgery has embarked on a solid and steady journey of development through seizing the opportunity, finding the right direction. On the way forward in the past twenty years, Chinese bariatric and metabolic surgery has not only faced setbacks and confusion, but also gained experience and lessons; it has encountered bottlenecks in its development and provided evidences from China. The number of surgeons in bariatric surgery is still limited compared with a large number of obese people. Therefore, there will be opportunities and challenges coexisting in the future. How to continuously improve the therapeutic effect of surgery, train more professional practitioners, break through the bottleneck, and seek faster development will be an important research topic in metabolic and bariatric surgery with the scientific evidence-based medicine accumulating.

ABSTRACT
Bariatric surgery is an effective method for the treatment of obesity and type 2 diabetes mellitus.Morbidly obese patients usually have metabolic syndromes,as such,surgeons need to choose the reasonable surgical methods for patients according to their individuality and particularity.Hiatal hernia is a very common disease prevalent in obese patients and could induce gastroesophageal reflux,which increases the difficulty of bariatric surgery and proposes higher demands on choice of surgical methods to surgeons.It is important to recognize the presence of the hiatal hernia preoperatively and choose a more effective procedure of bariatric surgery to decrease the incidence of postoperative complications.
