RESUMO
INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) is the most performed bariatric procedure worldwide. The most challenging postoperative complication is gastric leak. The objectives of this study are to examine the efficacy and morbidity of different therapeutic strategies addressing leakage, and the long-term outcomes of a cohort of LSG leaks. METHODS: A retrospective review of patients treated for LSG leaks between September 2014 and January 2023 at our high-volume bariatric surgery center was performed. RESULTS: The charts of 37 patients (29 women and 8 men) were reviewed, with a mean age of 43 years and a median follow-up of 24 months. The mean preoperative body mass index was 45.1 kg/m2. Overall, 30/37 (81%) patients were successfully treated with endoscopic management, and 7/37 (19%) ultimately underwent salvage surgery. If the leak was diagnosed earlier than 6 weeks, endoscopic treatment had a 97% success rate. The median number of endoscopic procedures was 2 per patient, and included internal pigtails, stents, septoplasty, endoluminal vacuum therapy and over-the-scope clips. Complications included stent-related ulcers (10), esophageal stenosis requiring endoscopic dilatations (4), stent migrations (2) and kinking requiring repositioning (1), and internal pigtail migration (3). Revisional surgery consisted of proximal gastrectomy and Roux-en-Y esophago-jejunal anastomosis, Roux-en-Y fistulo-jejunostomy or classic Roux-en-Y gastric bypass proximal to the gastric stricture. In 62% of the cases, the axis/caliber of the LSG was abnormal. Beyond 4 attempts, endoscopy was unsuccessful. The success rate of endoscopic management dropped to 25% when treatment was initiated more than 45 days after the index surgery. CONCLUSIONS: Purely endoscopic management was successful in 81% of cases; with 97% success rate if diagnosis earlier than 6 weeks. After four failed endoscopic procedures, a surgical approach should be considered. Delayed diagnosis appears to be a significant risk factor for failure of endoscopic treatment.

INTRODUCTION: Currently, bariatric surgery is the most effective treatment for the morbid obesity. It provides sustained weight loss as well as demonstrated positive effects on obesity-related comorbidities. The number of procedures performed worldwide has seen a sharp increase in the past twenty years. Therefore, an effort has been developed to establish a consensus in perioperative care based on best evidence. METHODS: The working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery Society and Czech Society of Obesitology prepared clinical practice guidelines for the ERAS (enhanced recovery after surgery) concept in perioperative care in bariatric surgery. The working group based its guidelines on ERAS guidelines published in 2021. The working group adopted the original text and then adapted the text and added its comments to specific items as appropriate. Electronic voting of all members of the working group was the final phase, by which the strength of consensus was expressed with respect to individual elements of the guidelines. RESULTS: The Czech working group reached a consensus with ERABS (enhanced recovery after bariatric surgery) guidelines for most elements. The quality of evidence is low for some interventions of the ERAS protocol for bariatric surgery. Therefore, extrapolation from other surgeries and fields is needed for evidence-based practice. CONCLUSION: The guidelines are intended for clinical practice in bariatric surgery with the ERAS protocol based on updated evidence and guidelines. It is based on recent and comprehensive ERAS guidelines adopted and adapted by the Czech working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery Society and Czech Society of Obesitology. Some supplementations and specifications are reflected in comments added to the Czech version.

Bariatric and metabolic surgery underwent substantial changes in its history. In the early nineties of the last century, the most important was introduction of laparoscopic procedures. Laparoscopic operations lead to worldwide adoption of bariatric surgery. Shift from bariatric to metabolic surgery represents another substantial change in treatment philosophy. In metabolic surgery, it is improvement/remission of metabolic parameters, such as type 2 diabetes mellitus and others, rather than weight loss what is the most important measure of success. Despite undoubtful success of surgical treatments, only a small proportion of the potentially eligible patients undergoes the operation. There are often fears of both patients and referring physicians of excessive invasiveness, risks and irreversible anatomical changes, mistrust in treatment results. Ongoing research targets these points, the goal is to master less invasive options than standard laparoscopic operations. Direct involvement of other medical specialties, such as gastroenterology or invasive radiology, in patient treatment is essential as well. Gastroenterology and endoscopic gastric plication, partial jejunal bypass and others may serve as the examples. Invasive radiology may offer potentially effective treatment modalities, such as embolization of left gastric artery. There's a trend in patients' preferences, towards less invasive treatment, even though it may result in moderate effectivity, rather than vice versa, choosing highly invasive, more risky treatment, regardless its expected higher efficacy.

INTRODUCTION: Historically, gastric bypass (GB) has been the oldest procedure used in bariatric surgery. Even though technically demanding, it had been the most widely used method for decades worldwide and still holds an irreplaceable position for its pronounced and long-term metabolic effect as well as for the therapeutic effect in gastroesophageal reflux (GERD). METHOD: The authors retrospectively analyse a series of 268 cases of GB, focusing on short-term weight loss, the metabolic effect on type two diabetes (T2DM), complication and reoperation rates and the BAROS scoring system in Roux-en-Y bypass (RYGB) and in minigastric bypass with one anastomosis (MGB/OAGB), comparing both of them to more frequently used gastric plication and sleeve gastrectomy. RESULTS: Both GB, without any increase in complication and reoperation rates, lead to a higher weight loss and the best BAROS scoring in comparison to other, simpler restrictive procedures. One year after GB, resolution of T2DM is seen in most diabetes patients operated on, the number needed to treat being.

BACKGROUND: Bariatric and metabolic surgery (BMS) is an effective treatment for patients with severe obesity. Patients with higher body mass index (BMI) and patients undergoing revisional surgery have a higher rate of major complications. This study purpose is to evaluate perioperative outcomes of patients with BMI ≥ 50 kg/m2. MATERIALS AND METHODS: A retrospective analysis of patients with a BMI ≥ 50 kg/m2 undergoing BMS between 2015 and 2023 was conducted. A comparative analysis was performed between patients undergoing primary versus revisional surgery. RESULTS: A total of 263 patients were included in the study. Primary procedures were performed in 220 patients (83.7%) and revisional procedures in 43 patients (16.3%). BMS included one anastomosis gastric bypass (n = 183), sleeve gastrectomy (n = 63), and other procedures (n = 17). Mean BMI was 54.6 with no difference between groups. There was no difference in baseline characteristics except the revisional group was older (44.8 ± 9.6 versus 39 ± 13 years; p = 0.006), had higher rates of gastroesophageal reflux disease (21% vs 7.3%; p = 0.005), and fatty liver disease (74% vs 55%; p = 0.02). There was perioperative mortality in three cases (1.1%) with no significant difference between groups. Leak rates were higher, and length of stay (LOS) was longer in the revisional group (4.6% vs 0.45%; p = 0.018 and 2.9 vs 3.7; p = 0.006, respectively). CONCLUSION: Revisional BMS in patients with a BMI ≥ 50 kg/m2 is associated with increased leak rates and LOS. Mortality rate is 1.1% and is insignificantly different between groups. Further prospective and large-scale studies are needed to clarify the optimal surgical approach to patients with extreme BMI including revisional surgery.

BACKGROUND: No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures. OBJECTIVES: The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair. SETTING: This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures. METHODS: The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone. RESULTS: A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%). CONCLUSION: Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.
RESUMO
Background: Bariatric and metabolic surgery often leads to significant changes in gut microbiota composition, indicating that changes in gut microbiota after bariatric and metabolic surgery might play a role in ameliorating type 2 diabetes (T2D). However, the effects of single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) on gut microbiota in T2D remain unclear. Objectives: To investigate the effects of SADI-S on gut microbiota and glucose metabolism in T2D rats. Methods: Nineteen T2D rats were randomly divided into the SADI-S group (n = 10) and the sham operation with pair-feeding group (sham-PF, n = 9). Fecal samples were collected to analyze the gut microbiota composition with 16S ribosomal DNA gene sequencing. The fasting blood glucose and glycated hemoglobin were measured to evaluate the effects of SADI-S on glucose metabolism. Results: The Chao and ACE index results indicated the richness of the gut microbial community. The ACE and Chao index values were significantly lower in the SADI-S group than in the sham-PF group, indicating that indicating that species richness was significantly lower in the SADI-S group than in the sham-PF group (p < 0.05). Shannon and Simpson indices were used to estimate the species diversity of the gut microbiota. Compared with the sham-PF group, the SADI-S group showed significantly lower Shannon index and higher Simpson index values, indicating that the species diversity was significantly lower in the SADI-S group than in the sham-PF group (p < 0.05). At the genus level, SADI-S significantly changed the abundances of 33 bacteria, including the increased anti-inflammatory bacteria (Akkermansia and Bifidobacterium) and decreased pro-inflammatory bacteria (Bacteroides). SADI-S significantly decreased the fasting blood glucose and glycated hemoglobin levels. The blood glucose level of rats was positively correlated with the relative abundances of 12 bacteria, including Bacteroides, and negatively correlated with the relative abundances of seven bacteria, including Bifidobacterium. Conclusion: SADI-S significantly altered the gut microbiota composition of T2D rats, including the increased anti-inflammatory bacteria (Akkermansia and Bifidobacterium) and decreased pro-inflammatory bacteria (Bacteroides). The blood glucose level of rats was positively correlated with the abundances of 12 bacteria, including Bacteroides, but negatively correlated with the relative abundance of 7 bacteria, including Bifidobacterium. These alternations in gut microbiota may be the mechanism through which SADI-S improved T2D. More studies should be performed in the future to validate these effects.
RESUMO
Obesity has long been recognized as a global epidemic. One of the most effective treatments is bariatric surgery. Since the first modern procedure was reported, it has evolved over time, and multiple techniques have emerged. More than 20 years ago, one of the most widely used techniques was the non-adjustable gastric band (NAGB), which showed very promising short-term results. However, over time, it became apparent that it was not as effective in the long term. Associated gastrointestinal symptoms, such as reflux and constant vomiting, along with considerable weight regain, caused this technique to fall out of favor and be replaced by other procedures like the gastric sleeve (GS). Although the technique has fallen into disuse and is no longer recommended in the literature, there are still patients with associated complications. Few recent cases associated with these complications have been reported. Most undergo band removal, and whether to perform another procedure remains with limited evidence. We present the case of a patient who underwent an NAGB procedure 10 years ago and later experienced symptoms (reflux) and weight regain. She successfully underwent band removal and conversion to a GS at our institute in Mexico.
RESUMO
Sodium-glucose co-transporter-2 inhibitors (SGLT2i) are glucose-lowering agents being increasingly used for cardio-renal protection in patients with or without type 2 diabetes (T2DM). This systematic review identified the clinical risk factors and outcomes of diabetic ketoacidosis (DKA) in patients undergoing bariatric and metabolic surgery (BMS) on SGLT2i. We found 12 studies with a total of 16 patients (10 females; mean age of 51 years). Apart from one patient, all patients developed DKA in the post-operative period presenting at a median of 5 days after surgery. Most of the patients were euglycaemic on presentation with DKA. Patients undergoing BMS on SGLT2i are at increased risk of developing DKA that can mimic post-operative surgical complications causing diagnostic dilemmas, especially with the euglycaemic variant, and delaying treatment.

INTRODUCTION: Parental predisposition and age of onset may be independently associated with 1-year total weight loss (TWL) failure (< 20%) after metabolic-bariatric surgery (MBS). METHODS: This cohort study includes all cases of the German StuDoQ|MBE register (2015-2019) with data on parental predisposition, obesity onset, and at least 1-year follow up after primary MBS procedures (n = 14,404). We provide descriptive statistics of the cohort in terms of the main outcome and 1-year TWL failure, and provide characteristics of surgery type subgroups. Finally, we provide a multivariate logistic regression model of 1-year TWL failure. RESULTS: 58.8% and 45.7% of patients reported maternal and paternal predisposition for obesity, respectively. Average onset of obesity was 15.5 years and duration of disease 28.3 years prior to MBS. SG is the most frequently performed procedure (47.2%) followed by RYGB (39.7%) and OAGB (13.1%). Mean 1-year TWL is 32.7 ± 9.3%, and 7.8% (n = 1,119) of patients show TWL failure (< 20%). Multivariate analysis shows independent association of early onset of obesity (< 18 years), male sex, age at operation, pre-operative BMI, pre-operative weight loss, sleeve gastrectomy (SG), and type 2 diabetes (T2D) with 1-year TWL failure (p < 0.001). CONCLUSION: The proportions of MBS patients that report on paternal and maternal predisposition for obesity are 45.7% and 58.8% respectively, and average age at onset is 15.5 years. 7.8% of patients do not meet current target criteria of successful response to surgery at 1 year. Early onset, male sex, age at operation, pre-operative BMI, pre-operative weight loss, SG, and T2D are independently associated with weight loss failure.

BACKGROUND AND AIMS: Bariatric and metabolic surgery (BMS) may adversely affect noninvasive stool tests for colorectal cancer (CRC) screening through several mechanisms. Multitarget stool DNA (mt-sDNA) is approved for CRC screening; however, performance in post-BMS patients is unknown. As the rates of BMS are anticipated to increase with rising incidence of obesity, it is important to evaluate mt-sDNA test performance among these patients. METHODS: In a multisite academic and community-based practice, we obtained mt-sDNA results from 10/2014 to 12/2019 through electronic records and an institutional BMS registry. Average CRC risk patients with BMS prior to a positive mt-sDNA underwent a detailed chart review. Follow-up colonoscopy findings were compared to those among BMS patients screened with colonoscopy alone and a historical cohort of patients without BMS, screened by mt-sDNA. The primary study endpoint was the positive predictive value (PPV) for advanced colorectal neoplasia. RESULTS: Among 336 average-risk patients who had mt-sDNA after BMS, mt-sDNA was positive in 49 (14.6%), 47/49 (96%) underwent follow-up colonoscopy, and the PPV for advanced neoplasia was 12/47 (25.5%). This is similar to the PPV for advanced colorectal neoplasia (425/1542, 28%) in a historical cohort of persons without prior BMS, screened by mt-sDNA at our center (P = .86). Among those who had prior BMS, the rate of advanced neoplasia was higher after mt-sDNA compared to screening colonoscopy alone. CONCLUSION: Despite anatomic and physiologic mechanisms that could alter blood or DNA content in stool, BMS does not appear to adversely affect the PPV of mt-sDNA.
RESUMO
Piriform fossa and/or esophageal injuries caused by calibration tubes are relatively rare and remain unelucidated. Herein, we report the case of a 36-year-old woman with morbid obesity, sleep apnea, and menstrual abnormalities who was scheduled to undergo laparoscopic sleeve gastrectomy (LSG). We inserted a 36-Fr Nelaton catheter made of natural rubber as a calibration tube during the surgery. However, excessive resistance was observed. We confirmed a submucosal layer detachment approximately 5 cm from the left piriform fossa to the esophagus using intraoperative endoscopy. Additionally, LSG was performed using an endoscope as the guiding calibration tube. We inserted a nasogastric tube under endoscopy with a guidewire before completing the surgery, hoping for a guiding effect on the saliva flow. After 17 months, the patient had successfully lost weight postoperatively without complaints of neck pain or discomfort during swallowing. Therefore, in cases where the damage is limited to the submucosal layer, as in this case, conservative therapy should be considered; this is similar to the concept of endoscopic submucosal dissection not requiring suture closure. This case highlights the risk of iatrogenic injuries to the piriform fossa and/or esophagus during LSG and the importance of careful calibration tube insertion to prevent them.
RESUMO
Epigenetic-sensitive mechanisms, mainly DNA methylation, mirror the relationship between environmental and genetic risk factors able to affect the sensitiveness to development of obesity and its comorbidities. Bariatric and metabolic surgery may reduce obesity-related cardiovascular risk through tissue-specific DNA methylation changes. Among the most robust results, differential promoter methylation of ACACA, CETP, CTGF, S100A8, and S100A9 genes correlated significantly with the levels of mRNA before and after gastric bypass surgery (RYGB) in obese women. Additionally, promoter hypermethylation of NFKB1 gene was significantly associated with reduced blood pressure in obese patients after RYGB suggesting useful non-invasive biomarkers. Of note, sperm-related DNA methylation signatures of genes regulating the central control of appetite, such as MC4R, BDNF, NPY, and CR1, and other genes including FTO, CHST8, and SH2B1 were different in obese patients as compared to non-obese subjects and patients who lost weight after RYGB surgery. Importantly, transgenerational studies provided relevant evidence of the potential effect of bariatric and metabolic surgery on DNA methylation. For example, peripheral blood biospecimens isolated from siblings born from obese mothers before bariatric surgery showed different methylation signatures in the insulin receptor and leptin signaling axis as compared to siblings born from post-obese mothers who underwent surgery. This evidence suggests that bariatric and metabolic surgery of mothers may affect the epigenetic profiles of the offspring with potential implication for primary prevention of severe obesity. We update on tissue-specific epigenetic signatures as potential mechanisms underlying the restoration of metabolic health after surgery suggesting useful predictive biomarkers.

INTRODUCTION: Following bariatric and metabolic surgery (BMS), patients may develop persistent cytopenia(s) despite adequate micronutrient levels. A comprehensive analysis of laboratory and hematopathologic findings in BMS patients with unexplained cytopenia(s) has not been previously described. METHODS: We reviewed the clinical and laboratory data, bone marrow histology, and used ancillary testing to characterize patients with a history of BMS who had subsequent bone marrow biopsies due to unexplained cytopenia(s). RESULTS: All patients had anemia and 59% (23/39) had additional cytopenias. Myelodysplastic syndrome (MDS) and clonal cytopenia of unknown significance (CCUS) were diagnosed in 8% (3/39) and 10% (4/39), respectively. Remaining cases were classified as idiopathic cytopenia of unknown significance (ICUS) with anemia alone (ICUS-A) in 47% (15/32) or multiple cytopenias (ICUS-PAN) in 53% (17/32). Time since surgery, age, or amount of weight loss was not associated with a specific diagnosis. No patient was vitamin B12 or folate deficient. However, vitamin B6 and zinc were decreased in 47% (5/11) and 29% (9/29), respectively. Examination of bone marrow aspirates revealed slight erythroid dyspoiesis affecting <10% of precursors in 60% (9/15) ICUS-A and 59% (10/17) ICUS-PAN. CONCLUSION: Bone marrow findings in patients with unexplained cytopenia(s) after BMS are not specific in the majority of cases, and caution is advised when interpreting dyserythropoiesis. Levels of micronutrients and vitamins other than iron, folate and vitamin B12 are frequently disturbed in this patient cohort and warrant correction and close clinical follow-up.

BACKGROUND: Bariatric medical tourism (BMT) is a rapidly expanding industry, with over 650 million people with obesity worldwide and total number rising by over 300% between 2003 and 2014. The overall health tourism industry is worth over $400 billion/year. METHODS: International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) conducted a global survey to analyze the details of BMT and the perceptions of bariatric health care professionals (HCP) regarding BMT. RESULTS: A total of 383 bariatric HCP's with experience of 272,548 procedures responded from 65 countries. Seventy-three percent of respondents had managed BMT patients, whilst low cost of surgery was felt to be the driving factor in 77% of cases. The USA contributed the most patients travelling for BMT with 11.6%. Twenty-four percent of respondents stated that they had no access to adequate notes regarding the patient's operation, whilst 12% felt BMT is associated with a higher mortality. Only 49% of respondents felt that IFSO guidelines were followed by the operating surgeon. Sleeve gastrectomy was the commonly offered surgery and an overall mean operation cost was $8716. Nearly 64% of respondents felt BMT needed better coordination between practitioners, whilst almost 85% of respondents supported the idea of a forum to facilitate safe BMT worldwide. CONCLUSION: This IFSO survey has outlined the current BMT trends worldwide and highlighted areas of concern in the care of such patients. It has expanded our knowledge and should be used as a starting point to establish international forums to aid collaboration.

This scoping review summarizes current evidence with regard to the impact of bariatric surgery on psychological health in adults with obesity. While a large body of evidence reports major metabolic benefit and improved quality of life, there is also ample evidence suggesting an increased incidence of self-harming behavior, a greater likelihood of developing an alcohol problem and higher rates of completed suicide among bariatric patients. Being able to identify the "at risk" patient population requires more longitudinal research into the risk factors for psychological complications after bariatric surgery. Bariatric surgery remains an extremely valuable long-term treatment option for managing obesity; however, there is a need to invest in mitigating psychological complications after the surgery, such as depression, alcohol consumption, and other self-harming behaviors.

BACKGROUND: Bariatric and metabolic surgery (BMS) is an established safe, effective, and durable treatment for obesity and its complications. However, there is still a paucity of evidence on surgery outcomes in patients suffering from extreme obesity. OBJECTIVES: This study aimed to evaluate outcomes of BMS in weight loss and the resolution of co-morbidities in patients with a body mass index (BMI) ≥70kg/m2. SETTING: National Health Service and private hospitals in the United Kingdom. METHODS: This cohort study analyzed prospectively collected records from the UK National Bariatric Surgery Registry of patients with a BMI ≥70 kg/m2 undergoing Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), or adjustable gastric band (AGB) between January 2009 and June 2014. RESULTS: There were 230 patients (64% female) eligible for inclusion in the study: 22 underwent AGB; 102 underwent SG, and 106 underwent RYGB. Preoperative weight and BMI values were comparable (76 ± 7 kg/m2 for AGB; 75 ± 5 kg/m2 for SG; 74 ± 5 kg/m2 for RYGB). The median postoperative follow-up was 13 months for AGB (10-22 mo), 18 for SG (6-28 mo), and 15 for RYGB (6-24 mo). Patients undergoing RYGB and SG exhibited the greatest postoperative total body weight loss (35 ± 13% and 31 ± 15%, respectively; P = .14), which led to postoperative BMIs of 48 ± 10 kg/m2 and 51 ± 11 kg/m2, respectively (P = .14). All procedures conferred a reduction in the incidence of co-morbidities, including type 2 diabetes, and led to improved functional statuses. The overall complication rate was 7%, with 3 deaths (1%) within 30 days of surgery. CONCLUSION: This study found that primary BMS in patients with a BMI >70kg/m2 has an acceptable safety profile and is associated with good medium-term clinical outcomes. RYGB and SG are associated with better weight loss and great improvements in co-morbidities than AGB. Given the noninferiority of SG outcomes and SG's potential for further conversion to other BMS procedures if required, SG may be the best choice for primary BMS in patients with extreme obesity.

Bariatric and metabolic surgery (BMS) is the most effective treatment for obesity, type 2 diabetes and co-morbidities, including nonalcoholic fatty liver disease and nonalcoholic steatohepatitis. The beneficial effects of BMS are beyond the primary goal of gastric restriction and nutrients malabsorption. Roux-en-Y gastric bypass and vertical sleeve gastrectomy are the 2 most commonly performed procedures of BMS. Both surgeries lead to physiologic changes in gastrointestinal tract; subsequently alter bile acids pool and composition, gut microbial activities, gut hormones, and circulating exosomes; and ultimately contribute to the improved glycemic control, insulin sensitivity, lipid metabolism, energy expenditure, and weight loss. The mechanisms underlying the benefits of BMS likely involve the bile acid-signaling pathway mediated mainly by nuclear farnesoid X receptor and the membrane Takeda G protein-coupled receptor, bile acids-gut microbiota interaction, and exosomes. In this review, we focus on recent advances in potential mechanisms and aim to learn novel insights into the molecular mechanisms underlying metabolic disorders.

Among Asian countries, laparotomic and laparoscopic bariatric surgeries were introduced in Japan after its establishment in Taiwan. However, despite high prevalence of potential patients with obesity and diabetes, the wider incorporation of surgery into treatment regimen has been stalling for decades in Japan. While the unique Japanese national health insurance system has guaranteed fair healthcare delivery, it might have worked as a barrier to the development of bariatric and metabolic surgeries (BMS). The present article reviews the status of BMS in Japan and discusses recent issues related to its use. To focus on and identify the major obstacles inhibiting the widespread use of BMS, we have comprehensively covered some major areas including the insurance system, surgical indication, accreditation and training system, original research, and national registry.

The world has been struggling with the COVID-19 virus since December 2019. Turkey has also been battling with the virus since March 2019. While struggling with this unknown virus, we have postponed our new bariatric surgeries like most elective surgery. However, curfew and quarantine period (increase in food intake and decreased physical activity) increases risks for morbidity and mortality because of obesity and diabetes.
