Valezi AC, Campos ACL, Bahten LCV. BRAZILIAN MULTI-SOCIETY POSITION STATEMENT ON EMERGING BARIATRIC AND METABOLIC SURGICAL PROCEDURES. ARQUIVOS BRASILEIROS DE CIRURGIA DIGESTIVA : ABCD = BRAZILIAN ARCHIVES OF DIGESTIVE SURGERY 2023; 36:e1759. [PMID: 37729276 PMCID: PMC10510373 DOI: 10.1590/0102-672020230041e1759] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 07/13/2023] [Indexed: 09/22/2023]
Abstract
This Brazilian multi-society position statement on emerging bariatric and metabolic surgical procedures was issued by the Brazilian Society of Bariatric and Metabolic Surgery (SBCBM), the Brazilian College of Digestive Surgery (CBCD), and the Brazilian College of Surgeons (CBC). This document is the result of a Brazilian Emerging Surgeries Forum aimed at evaluating the results of surgeries that are not yet listed in the Federal Council of Medicine (CFM), the regulatory agency that oversees and regulates medical practice in Brazil. The Forum integrated more than 400 specialists and academics with extensive knowledge about bariatric and metabolic surgery, representing the three surgical societies: SBCBM, CBC, and CBCD. International speakers participated online and presented their experiences with the techniques under discussion, emphasizing the regulatory policies in their countries. The indications for surgery and the subsequent procedures were carefully reviewed, including one anastomosis gastric bypass (OAGB), single anastomosis duodeno-ileal with sleeve gastrectomy (SADI-S or OADS), sleeve gastrectomy with transit bipartition (SGTB), and sleeve gastrectomy with ileal interposition (SGII). The recommendations of this document are based on an extensive literature review and discussions among bariatric surgery specialists from the three surgical societies. We concluded that patients with a body mass index over 30 kg/m2 may be candidates for metabolic surgery in the presence of comorbidities (arterial hypertension and type 2 diabetes) with no response to clinical treatment of obesity or in the control of other associated diseases. Regarding the surgical procedures, we concluded that OAGB, OADS, and SGTB are associated with low morbidity rates, satisfactory weight loss, and resolution of obesity-related comorbidities such as diabetes and arterial hypertension. SGII was considered a good and viable promising surgical alternative technique. The recommendations of this statement aim to synchronize our societies with the sentiments and understandings of most of our members and also serve as a guide for future decisions regarding bariatric surgical procedures in our country and worldwide.

Abstract
Current views show that an impaired balance partly explains the fat accumulation leading to obesity. Fetal malnutrition and early exposure to endocrine-disrupting compounds also contribute to obesity and impaired insulin secretion and/or sensitivity. The liver plays a major role in systemic glucose homeostasis through hepatokines secreted by hepatocytes. Hepatokines influence metabolism through autocrine, paracrine, and endocrine signaling and mediate the crosstalk between the liver, non-hepatic target tissues, and the brain. The liver also synthetizes bile acids (BAs) from cholesterol and secretes them into the bile. After food consumption, BAs mediate the digestion and absorption of fat-soluble vitamins and lipids in the duodenum. In recent studies, BAs act not simply as fat emulsifiers but represent endocrine molecules regulating key metabolic pathways. The liver is also the main site of the production of ketone bodies (KBs). In prolonged fasting, the brain utilizes KBs as an alternative to CHO. In the last few years, the ketogenic diet (KD) became a promising dietary intervention. Studies on subjects undergoing KD show that KBs are important mediators of inflammation and oxidative stress. The present review will focus on the role played by hepatokines, BAs, and KBs in obesity, and diabetes prevention and management and analyze the positive effects of BAs, KD, and hepatokine receptor analogs, which might justify their use as new therapeutic approaches for metabolic and aging-related diseases.

Postprandial hypoglycemia after ileocolic interposition and Billroth-II gastrojejunostomy: A case report. Clin Case Rep 2023; 11:e7060. [PMID: 36950668 PMCID: PMC10025248 DOI: 10.1002/ccr3.7060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/03/2023] [Accepted: 02/22/2023] [Indexed: 03/24/2023] Open
Abstract
Postprandial reactive hypoglycemia, or late dumping syndrome, is a common but underrecognized complication from bypass surgery. We report an unusual case of postprandial reactive hypoglycemia in a patient with a severe esophageal stricture from corrosive agent ingestion who underwent ileocolic interposition and an antecolic Billroth-II gastrojejunostomy. A 22-year-old male patient with a one-year history of corrosive ingestion was referred to the hospital for a surgical correction of severe esophageal stricture. After the patient underwent ileocolic interposition and an antecolic Billroth-II gastrojejunostomy, he experienced multiple episodes of gastroesophageal refluxsymptoms during nasogastric feeding and had onset of hypoglycemic symptoms. His plasma glucose level was 59 mg/dL. After we had intraoperatively re-inserted a jejunostomy tube bypassing the ileocolic interposition, and reintroduced enteral nutrition, his hypoglycemic symptoms resolved. We performed a mixed meal tolerance test by nasogastric tube, but the results did not show postprandial hypoglycemia. Although the specific mechanism is unclear, this case suggests gastroesophageal reflux to the ileal interposition may have caused a state of exaggerated hyperinsulinemic response and rebound hypoglycemia. To the best of our knowledge, we are the first to report case of postprandial hypoglycemia after ileocolic interposition, which may have been caused by exaggerated hyperinsulinemic response due to gastroesophageal reflux to the ileal interposition. This syndrome should be considered in the patient who has had ileocolic interposition surgery and has developed postprandial hypoglycemia.

Abstract
Obesity is rapidly increasing and has reached epidemic features worldwide. It´s linked to insulin resistance, systemic low-grade inflammation and common pathogenic pathways with a number of comorbidities (including cancer), leading to high mortality rates. Besides change of lifestyles (diet and physical exercise) and pharmacological therapy, bariatric surgery is able to rapidly improve several metabolic and morphologic features associated with excessive fat storage, and currently represents an in vivo model to study the pathogenic mechanisms underlying obesity and obesity-related complications. Studies on obese subjects undergoing bariatric surgery find that the effects of surgery are not simply secondary to gastric mechanical restriction and malabsorption which induce body weight loss. In fact, some surgical procedures positively modify key pathways involving the intestine, bile acids, receptor signaling, gut microbiota, hormones and thermogenesis, leading to systemic metabolic changes. Furthermore, bariatric surgery represents a suitable model to evaluate the gene-environment interaction and some epigenetic mechanisms linking obesity and insulin resistance to metabolic diseases.

Surgical cure for type 2 diabetes by foregut or hindgut operations: a myth or reality? A systematic review. Surg Endosc 2016; 31:25-37.

Abstract
BACKGROUND Bariatric surgery results in remission of type 2 diabetes mellitus in a significant proportion of patients. Animal research has proposed the foregut and hindgut hypotheses as possible mechanisms of remission of T2DM independent of weight loss. These hypotheses have formed the basis of investigational procedures designed to treat T2DM in non-obese (in addition to obese) patients. The aim of this study was to review the procedures that utilise the foregut and hindgut hypotheses to treat T2DM in humans. METHODS A systematic review was conducted to identify the investigational procedures performed in humans that are based on the foregut and hindgut hypotheses and then to assess their outcomes. RESULTS Twenty-four studies reported novel procedures to treat T2DM in humans; only ten utilised glycated haemoglobin A1c (HbA1c) in their definition of remission. Reported remission rates were 20-40 % for duodenal-jejunal bypass (DJB), 73-93 % for duodenal-jejunal bypass with sleeve gastrectomy (DJB-SG), 62.5-100 % for duodenal-jejunal bypass sleeve (DJBS) and 47-95.7 % for ileal interposition with sleeve gastrectomy (II-SG). When using a predetermined level of HbA1c to define remission, the remission rates were lower (27, 63, 0 and 65 %) for DJB, DJB-SG, DJBS and II-SG. CONCLUSIONS The outcomes of the foregut- and hindgut-based procedures are not better than the outcomes of just one of their components, namely sleeve gastrectomy. The complexity of these procedures in addition to their comparable outcomes to a simpler operation questions their utility.

Abstract
Nowadays, the surgical techniques for treating type 2 diabetes (T2DM) include: Ileal Interposition (II), Ileal Interposition in combination with Sleeve Gastrectomy (IISG) and Diverted Sleeve Gastrectomy (IIDSG). These procedures are not only for obese subjects, but are also used for non-obese subjects. These types of surgical procedures can improve glycemic control, and lead to a significant reduction in oral hypoglycemic agents (OHAs) and insulin therapy. The results of various studies have shown the safety, feasibility, and efficacy of the surgical procedure for the treatment of T2DM. Although it is an effective treatment option, this procedure is not recommended for general use and long-term studies are needed to confirm these findings and potential side effects on a larger number of patients.

Abstract
Background Type 2 diabetes mellitus (T2DM) has gained pandemic proportions becoming a global threat within the last few decades. In parallel to the increasing prevalence, healthcare costs have become a huge economic burden for the hospital and governments. Bariatric surgery has been proven to induce glycemic control in obese type 2 diabetics. However, the cost effectiveness of metabolic surgery in overweight, obese and morbidly obese individuals has not been documented. We aimed to demonstrate the efficacy and reduced diabetic-medication cost after diverted sleeve gastrectomy with ileal interposition (DSIT) in type 2 diabetic individuals followed more than 1 year. Methods Records of 116 type 2 diabetic patients operated by DSIT at a dedicated metabolic surgery clinic between October 2011 and April 2013 were retrospectively reviewed. A comparison was made between the annual diabetic medication cost before and after surgery using the paired t test. The alterations in BMI and HbA1c were recorded and analyzed. Results Diverted sleeve gastrectomy with ileal interposition led to a marked reduction in BMI and improved glycemic control after 1 year follow-up. Mean HbA1c levels decreased from a mean of 8.9 ± 1.7 to 6.6 ± 1.1 1 year after surgery (p < 0.001). Mean preoperative BMI declined from 32.9 ± 4.3 to 24.7 ± 2.7 kg/m2 (p < 0.001). Cost of diabetic medication decreased from a mean 660.08 USD/year to 65.12 USD 1 year after surgery (p < 0.001). Conclusion Our results have shown that DSIT operation leads to a significantly better glycemic control and lower diabetic medication costs at 1 year.

Abstract
Medical therapy for type 2 diabetes mellitus is ineffective in the long term due to the progressive nature of the disease, which requires increasing medication doses and polypharmacy. Conversely, bariatric surgery has emerged as a cost-effective strategy for obese diabetic individuals; it has low complication rates and results in durable weight loss, glycemic control and improvements in the quality of life, obesity-related co-morbidity and overall survival. The finding that glucose homeostasis can be achieved with a weight loss-independent mechanism immediately after bariatric surgery, especially gastric bypass, has led to the paradigm of metabolic surgery. However, the primary focus of metabolic surgery is the alteration of the physio-anatomy of the gastrointestinal tract to achieve glycemic control, metabolic control and cardio-metabolic risk reduction. To date, metabolic surgery is still not well defined, as it is used most frequently for less obese patients with poorly controlled diabetes. The mechanism of glycemic control is still incompletely understood. Published research findings on metabolic surgery are promising, but many aspects still need to be defined. This paper examines the proposed mechanism of diabetes remission, the efficacy of different types of metabolic procedures, the durability of glucose control, and the risks and complications associated with this procedure. We propose a tailored approach for the selection of the ideal metabolic procedure for different groups of patients, considering the indications and prognostic factors for diabetes remission.

Abstract
Background Remission of diabetes is seen in more than 60% of patients after bariatric surgery. There is extensive variability in the remission rates between different surgical procedures. We analyzed our database and aimed to develop an easy scoring system to predict the probability of diabetes remission after two surgical procedures i.e. Ileal Interposition coupled with Sleeve Gastrectomy (IISG) or Diverted Sleeve Gastrectomy (IIDSG). Methods In this retrospective study, we analyzed records pertaining to patients who underwent IISG (n = 46) and IIDSG (n = 29). The primary outcome measure was diabetes remission (A1c <6.5% and not requiring hypoglycemic drugs). We identified seven preoperative clinical variables (age, duration of diabetes, body mass index, micro and macrovascular complications, use of insulin and stimulated C-peptide) based on our previous reports to be included in the diabetes remission score (DRS). The DRS score (7 – 14) was compared between the patients with and without remission in both the surgery groups. Results Mean DRS in patients who underwent IISG was 9.2 ± 1.4. Twenty one (46%) had a remission in diabetes. DRS was significantly lower in patients with remission than patients without remission (8.1 ± 0.8 versus 10.2 ± 0.9, p < 0.0001). Mean DRS in patients who underwent IIDSG was 10.4 ± 1.3. Twenty one (72%) had a remission in diabetes. DRS was significantly lower in patients with remission than patients without remission (9.7 ± 0.8 versus 12.0 ± 0.5, p < 0.0001). Patients with a DRS ≥ 10 in IISG group and more than 12 in IIDSG group did not get into remission. Conclusion Preoperative DRS can be a useful tool to select the type of surgical procedure and to predict the postoperative diabetes remission. Trial registration NCT00834626.

Abstract
High glycated hemoglobin A1c (HbA1c) is strongly correlated with developing type 2 diabetes mellitus (T2DM) complications; this study reviews the efficacy of various types of metabolic surgeries in reducing HbA1c levels in type 2 diabetics with BMI <35 kg/m(2). An electronic search of MEDLINE databases using terms 'metabolic surgery', type 2 diabetes mellitus, BMI <35 kg/m(2), and related keywords for studies published between 1987 and 2013. Data from 53 articles with 2,258 patients were selected for this review. The weighted mean change in HbA1c was -2.8 % (95 % CI -2.8 to -2.7, p < 0.01) and weighted mean BMI change was -5.5 kg/m(2) (95 % CI -5.6 to -5.4, p < 0.01). There was a strong correlation between weighted percentage mean change in HbA1c and BMI. Adjustable gastric banding and duodenal jejunal bypass were inferior to other surgeries in reducing BMI and HbA1c in BMI <35 kg/m(2). Metabolic surgery significantly decreases HbA1c in T2DM patients with BMI <35 kg/m(2) and that the magnitude of HbA1c change may be a useful surrogate of DM control.

Abstract
Bariatric surgery was developed with the aim of weight reduction. Success was defined only by excess weight loss. Other indices of resolution of metabolic comorbidities were reported, but were mostly secondary. Several communications have reported that regardless of body mass index (BMI), complete or partial remission of type 2 diabetes mellitus (T2DM) is possible. These results mostly occur before weight loss, positioning metabolic surgery as a good tool for controlling the current T2DM epidemic. Medical treatment is evolving, but is expensive and not risk-free. Surgery aimed mainly at diseases such as diabetes and not weight loss are referred to as "metabolic surgery." Metabolic surgery has been proven to be safe and effective, and although more data are needed, it is unquestionable that a new discipline has been founded. Metabolic surgery can effectively treat T2DM in individuals with any BMI, including that below 35 kg/m(2).

Abstract
Glycemic control and its benefits in preventing microvascular diabetic complications are convincingly proved by various prospective trials. Diabetes control and complications trial (DCCT) had reported variable glycated hemoglobin (HbA1C) as a cause of increased microvascular complications in conventional glycemic control group versus intensive one. However, in spite of several indirect evidences, its link with cardiovascular events or macrovascular complications is still not proved. Glycemic variability (GV) is one more tool to explain relation between hyperglycemia and increased cardiovascular risk in diabetic patients. In fact GV along with fasting blood sugar, postprandial blood sugar, HbA1C, and quality of life has been proposed to form glycemic pentad, which needs to be considered in diabetes management. Postprandial spikes in blood glucose as well as hypoglycemic events, both are blamed for increased cardiovascular events in Type 2 diabetics. GV includes both these events and hence minimizing GV can prevent future cardiovascular events. Modern diabetes management modalities including improved sulfonylureas, glucagon like peptide-1 (GLP-1)-based therapy, newer basal insulins, and modern insulin pumps address the issue of GV effectively. This article highlights mechanism, clinical implications, and measures to control GV in clinical practice.

Abstract
OBJECTIVE To determine the frequency of initial misclassification of diabetes mellitus (DM) in children and to compare the presenting features of DM1, DM2, and the misclassified cases. RESULTS A total of 206 patients fulfilled the inclusion criteria. Of them, 74.75% had DM1 and 25.25% had DM2. Ten percent of studied patients had a subsequent change in classification. The mean HbA1c of the DM2 patients, who were initially misclassified, was 13.35% (SD = 1.96). The mean HbA1c of DM2 patients with correct initial classification was 8.83% (SD = 3.01). Diabetes ketoacidosis (DKA) was seen in 59.44% of DM1 and 23.91% of DM2 patients. Of the DM2 patients who were initially misclassified, 58.82% had presented in DKA as opposed to only 6.45% of patients who were correctly classified. CONCLUSION The initial classification of DM frequently requires revision (10% in this study). The misclassification is highest among DM2 patients who initially present with higher HbA1c and DKA.

Abstract
AIM Combination of laparoscopic ileal interposition (II) with sleeve gastrectomy (SG) is an upcoming procedure, which offers good metabolic improvement and weight reduction without causing significant malabsorption. The objective of this study was to evaluate the results of this novel procedure for control of type 2 diabetes, obesity, hypertension, and related metabolic abnormalities. MATERIALS AND METHODS The II and SG was performed in 43 patients (M:F = 25:18) from February 2008. Participants had a mean age of 47.2 ± 8.2 years (range 29-66 years), mean duration of diabetes of 10.1 ± 9.2 years (range 1-32 years), and mean preoperative body mass index (BMI) of 33.2 ± 7.8 kg/m2. All patients had poorly controlled type 2 diabetes mellitus (DM) [mean glycated hemoglobin (HbA1C) 9.6 ± 2.1%] despite use of oral hypoglycemic agents (OHAs) and/or insulin. Thirty (70%) patients had hypertension, 20 (46%) had dyslipidemia, and 18 (42%) had significant microalbuminuria. The primary outcome was remission of diabetes (HbA1C < 6.5% without OHAs/insulin) and the secondary outcomes were reduction in antidiabetic agent requirement and components of metabolic syndrome. RESULTS Mean follow-up was for 20.2 ± 8.6 months (range 4-40 months). Postoperatively, glycemic parameters (fasting and post-lunch blood sugar, HbA1C improved in all patients (P < 0.05) at all intervals. Twenty (47%) patients had remission in diabetes and the remaining patients showed significantly decreased OHA requirement. All patients had weight loss between 15 and 30% (P < 0.05). Twenty-seven (90%) patients had remission in hypertension. At 3 years, the mean fall in HbA1C (34%) was more than reduction in BMI (25%). There was a declining trend in lipids and microalbuminuria postoperatively, though it was significant for microalbuminuria only. CONCLUSIONS The laparoscopic II with SG seems to be a promising procedure for control of type 2 DM, hypertension, weight reduction, and associated metabolic abnormalities. A multicenter study with larger number of patients and a longer follow-up period is needed to substantiate our preliminary findings.

Abstract
OBJECTIVE The objective of the present study was to prospectively evaluate the results of laparoscopic ileal interposition (II) with diverted sleeve gastrectomy (DSG) for control of T2DM and related metabolic abnormalities. METHODS All patients underwent II +DSG. They had T2DM≥5 years with poor glycemic control despite adequate dosage of oral hypoglycemic agents (OHAs) and/or insulin. The primary outcome was remission of diabetes (HbA1C<6.5% without OHAs/insulin), and secondary outcomes were reduction in antidiabetic agent requirement and components of metabolic syndrome. RESULTS We report the preliminary postoperative follow-up data of 9.1±5.3 months (range: 3-21 months). There were 17 patients (male:female=12:5) with mean age of 50.7±8.1 (range, 34-66 years), duration of diabetes of 15.1±5.8 years (range, 5-30 years), and preoperative body mass index of 29.2±7.5 kg/m(2)(range, 22.4-37.5 kg/m(2)). Eight patients (45%) had hypertension, while dyslipidemia and microalbuminuria was present in 7 patients (39%) each. Twelve patients (70.5%) had diabetes remission. Seven/eight (87.5%) patients had remission in hypertension. All participants had weight loss ranging between 15% and 30%. Postoperatively statistically significant decline was observed in the glycemic and lipid parameters, microalbuminuria at all intervals (p<0.05). Two patients had vitamin B12 deficiency 1 year after surgery. CONCLUSION Ileal interposition combined with DSG addresses both foregut and hindgut theories and brings about remissions in T2DM patients with reasonable safety. Our preliminary observations demonstrated the feasibility and efficacy of this novel surgical procedure as a promising option in T2DM.

Abstract
Roux-en-Y gastric bypass (RYGB) greatly improves glycaemic control in morbidly obese patients with type 2 diabetes, in many even before significant weight loss. Understanding the responsible mechanisms may contribute to our knowledge of the pathophysiology of type 2 diabetes and help identify new drug targets or improve surgical techniques. This review summarises the present knowledge based on pathophysiological studies published during the last decade. Taken together, two main mechanisms seem to be responsible for the early improvement in glycaemic control after RYGB: (1) an increase in hepatic insulin sensitivity induced, at least in part, by energy restriction and (2) improved beta cell function associated with an exaggerated postprandial glucagon-like peptide 1 secretion owing to the altered transit of nutrients. Later a weight loss induced improvement in peripheral insulin sensitivity follows.

Abstract
BACKGROUND The objective of this study was to evaluate the mid-term outcomes of the laparoscopic ileal interposition into the jejunum (JII-SG) or into the duodenum (DII-SG) associated with sleeve gastrectomy for type 2 diabetes mellitus (T2DM) patients with BMI below 35. METHODS The procedures were performed on 202 consecutive patients. Mean age was 52.2 ± 7.5. Mean duration of T2DM was 9.8 ± 5.2 years. Insulin therapy was used by 41.1%. Dyslipidemia was observed in 78.2%, hypertension in 67.3%, nephropathy in 49.5%, retinopathy in 31.2%, coronary heart disease in 11.9%, and other cardiovascular events in 12.9%. RESULTS Mean follow-up was 39.1 months (range, 25-61). Early and late mortality was 0.99% and 1.0%, respectively. Early reoperation was performed in 2.5%. Early and late major complications were 8.4% and 3.5%. Early most frequent complications were pneumonia and ileus. Intestinal obstruction was diagnosed in 1.5%. Mean BMI decreased from 29.7 to 23.5 kg/m(2), mean fasting glucose from 202.1 to 112.2 mg/dl, and mean postprandial glucose from 263.3 to 130 mg/dl. Triglycerides diminished from a mean of 273.4 to 110.3 mg/dl and cholesterol from a mean of 204.7 to 160.1 mg/dl. Hypertension was resolved in 87.5%. Mean hemoglobin A(1c) (HbA(1c)) decreased from 8.7 to 6.2% after the JII-SG and to 5.9% following the DII-SG. HbA(1c) below 7% was seen in 89.9% of the patients and below 6.5% in 78.3%. Overall, 86.4% of patients were off antidiabetic medications. CONCLUSION Both JII-SG and DII-SG demonstrated to be safe, effective, and long-lasting alternatives for the treatment of T2DM patients with BMI <35. Beyond glycemic control, other benefits were achieved.
