One anastomosis gastric bypass surgery in Type2 diabetes patients with body mass index < 35 kg/m2: A multi-center retrospective cohort study. Ann Med Surg (Lond) 2022; 79:104102. [PMID: 35860068 PMCID: PMC9289504 DOI: 10.1016/j.amsu.2022.104102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 06/25/2022] [Accepted: 06/25/2022] [Indexed: 11/23/2022] Open
Abstract
Introduction Bariatric surgeries have shown efficacy in weight reduction, glycemic control and improvement of type-2 diabetes (T2DM) in patients with obesity. We aimed to assess the efficacy of one anastomosis gastric bypass surgery (OAGB) in T2DM patients with body mass index (BMI) < 35 kg/m2 within a year after surgery. Methods In this multicenter retrospective cohort study, 14 T2DM patients with BMI <35 kg/m2 (females, %: 71.4% (10 of 14), and age, mean (standard deviation): 51.2 (12.3) years) who had underwent OAGB surgery by the same surgeon, were followed at intervals of one, three, six, and 12 months after surgery. The remission rates of T2DM were calculated and the metabolic indices were compared using paired t-test and Wilcoxon rank test. Results No adverse outcomes were detected 12 months after surgery. Within six months, seven (50%) patients underwent remission (one (7.1%) within one, three (21.4%) within three, and three (21.4%) within six months). Post-operative weight (p < 0.001) and fasting blood glucose (p < 0.01) in all time periods were significantly lower compared to pre-operative values. Hemoglobin A1C (HbA1C) was significantly lower at three- and six-month intervals (p < 0.05) but not at twelve months (p = 0.2). Thyroid-stimulating hormone and triglyceride levels were lower at six months compared to pre-surgical levels (p < 0.05) but cholesterol levels were not different in any of time points (p > 0.05). Conclusion OAGB surgery is associated with weight reduction, glycemic control and a 50% remission rate within six months in patients with diabetes and BMI <35 kg/m2. One anastomosis gastric bypass (OAGB) surgery has shown efficacy in patients with BMI >35 kg/m2. Less is known about the efficacy of OAGB in BMI <35 kg/m2, especially diabetes-related outcomes. OAGB was associated with a 50% rate of diabetes remission within six months in patients with BMI <35 kg/m2. Within a one-year follow-up, OAGB was associated with improvement of glycemic and metabolic indices.

Abstract
The metabolic syndrome, by definition, is not a disease but is a clustering of individual metabolic risk factors including abdominal obesity, hyperglycemia, hypertriglyceridemia, hypertension, and low high-density lipoprotein cholesterol levels. These risk factors could dramatically increase the prevalence of type 2 diabetes and cardiovascular disease. The reported prevalence of the metabolic syndrome varies, greatly depending on the definition used, gender, age, socioeconomic status, and the ethnic background of study cohorts. Clinical and epidemiological studies have clearly demonstrated that the metabolic syndrome starts with central obesity. Because the prevalence of obesity has doubly increased worldwide over the past 30 years, the prevalence of the metabolic syndrome has markedly boosted in parallel. Therefore, obesity has been recognized as the leading cause for the metabolic syndrome since it is strongly associated with all metabolic risk factors. High prevalence of the metabolic syndrome is not unique to the USA and Europe and it is also increasing in most Asian countries. Insulin resistance has elucidated most, if not all, of the pathophysiology of the metabolic syndrome because it contributes to hyperglycemia. Furthermore, a major contributor to the development of insulin resistance is an overabundance of circulating fatty acids. Plasma fatty acids are derived mainly from the triglycerides stored in adipose tissues, which are released through the action of the cyclic AMP-dependent enzyme, hormone sensitive lipase. This review summarizes the latest concepts in the definition, pathogenesis, pathophysiology, and diagnosis of the metabolic syndrome, as well as its preventive measures and therapeutic strategies in children and adolescents.

Abstract
CONTEXT Exaggerated postprandial glucagon-like peptide-1 (GLP-1) secretion seems important for weight loss and diabetes remission after Roux-en-Y gastric bypass (RYGB) and may result from carbohydrate absorption in the distal small intestine. OBJECTIVE To investigate distal [GLP-1; peptide YY (PYY)] and proximal [glucose-dependent insulinotropic polypeptide (GIP)] gut hormone secretion in response to carbohydrates hydrolyzed at different rates. We hypothesized that slow digestion restricts proximal absorption, facilitating distal delivery of carbohydrates and thereby enhanced GLP-1 secretion in unoperated individuals, whereas this may not apply after RYGB. DESIGN Single-blinded, randomized, crossover study. SETTING Hvidovre Hospital, Hvidovre, Denmark. PARTICIPANTS Ten RYGB-operated patients and 10 unoperated matched subjects. INTERVENTIONS Four separate days with ingestion of different carbohydrate loads, either rapidly/proximally digested (glucose plus fructose; sucrose) or slowly/distally digested (isomaltulose; sucrose plus acarbose). MAIN OUTCOME MEASURES GLP-1 secretion (area under the curve above baseline). Secondary outcomes included PYY and GIP. RESULTS Isomaltulose enhanced secretion of GLP-1 nearly threefold (P = 0.02) and PYY ninefold (P = 0.08) compared with sucrose in unoperated subjects but had a modest effect after RYGB. Acarbose failed to increase sucrose induced GLP-1 secretion in unoperated subjects and diminished the responses by 50% after RYGB (P = 0.03). In both groups, GIP secretion was reduced by isomaltulose and even more so by sucrose plus acarbose when compared with sucrose intake. CONCLUSIONS GLP-1 secretion depends on the rate of carbohydrate digestion, but in a different manner after RYGB. Enhanced GLP-1 secretion is central after RYGB, but it may also be obtained in unoperated individuals by delaying hydrolysis of carbohydrates, pushing their digestion and absorption distally in the small intestine.

Abstract
BACKGROUND Sleeve gastrectomy plus side-to-side jejunoileal anastomosis (JI-SG), a relatively new approach to bariatric surgeries, has shown promising results for treating obesity and metabolic comorbidities. This study investigated the feasibility and safety of JI-SG in weight loss and diabetes remission compared with sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). METHODS Forty 10-week-old male Zucker diabetic fatty rats were randomly assigned to four groups: control, SG, JI-SG, and RYGB. Their body weights, food intake, and levels of gut hormones (ghrelin, insulin, and glucagon-like peptide-1 (GLP-1)) and lipids were measured. RESULTS Rats in the SG, JI-SG, and RYGB groups demonstrated lower food intake and more weight loss 2 weeks postoperatively compared with control rats. Furthermore, rats in the JI-SG group achieved more weight loss (mean 242.7 ± 11.2 g) compared with those in the SG and RYGB groups (SG, 401.4 ± 15.1 g and RYGB, 298 ± 12 g, both P < 0.01). All surgery groups demonstrated a decreased fasting insulin, serum glucose, lipid levels, and increased GLP-1 postoperatively. The JI-SG group had lower fasting ghrelin levels than the RYGB group (168 ± 19.8 ng/L vs. 182 ± 16.7 ng/L, P < 0.01) and higher fasting GLP-1 levels than the SG group (1.99 ± 0.11 pmol/L vs. 1.71 ± 0.12 pmol/L, P < 0.01) at 12 weeks postoperatively. Over the experimental period, the ghrelin levels slowly increased in all surgical groups but remained lower than the preoperative and control levels. CONCLUSIONS JI-SG induced higher ghrelin and GLP-1 levels and improved glycemic control in Zucker diabetic fatty rats. Compared with SG and RYGB, JI-SG appeared to be a simple, relatively safe, and more effective procedure for treating type 2 diabetes and obesity in this animal model.

Abstract
BACKGROUND Metabolic surgery is a novel therapy for mild obesity (BMI 30-35 Kg/m(2)) in type 2 diabetes mellitus (T2DM) patients. The ABCD score, which comprise age, BMI, C-peptide level, and duration of T2DM (years), was reported as useful in predicting the success of T2DM treatment using metabolic surgery. This study examines gastric bypass and sleeve gastrectomy as a salvage treatment for non-obese (BMI < 30 kg/m(2)) T2DM patients and evaluates the role of ABCD scores. METHODS From January 2007 to July 2013, 512 (71.2%) of 711 T2DM patients enrolled in a metabolic surgical program had at least 1-year follow-up were recruited. Clinical data and outcomes of 80 (15.6%) patients with BMI < 30 Kg/m(2) were compared with those of the other 432 (84.4%) patients with BMI ≥ 30 Kg/m(2). Complete remission was defined as HbA1c ≤ 6%, and partial remission was defined as HbA1c < 6.5%. A binary logistic regression was used to identify predictors of T2DM remission. RESULTS Mean age of the 80 non-obese T2DM patients was 47.7 ± 9.1 years, and mean HbA1c and disease duration were 9.1 ± 1.8% and 6.5 ± 5.1 years, respectively. Mean total body weight loss was 17.1 ± 7.4% at 1 year, and mean BMI decreased from 26.9 ± 2.2 to 22.7 ± 2.5 kg/m(2) at 1 year. Complete remission of T2DM was achieved in 25.0% of patients, and partial remission was achieved in 23.8%. The complete remission rate was significantly lower than the 49.5% found in patients with BMI 30-35 and 79.0% of patients with BMI > 35 Kg/m(2). In univariate analysis, non-obese patients who had T2DM remission after surgery were heavier and had a wider waist, higher C-peptide levels, shorter disease duration, more weight loss, and higher ABCD score than those without remission. The ABCD score remained the only independent predictor of success after multivariate logistical regression analyses (P = 0.003). CONCLUSIONS Metabolic surgery may be useful in achieving glycemic control of selected non-obese T2DM patients. The ABCD score is a simple multidimensional grading system that can predict the success of T2DM treatment.

Abstract
Background In this study, we specifically aimed to analyze the technical and safety aspects of laparoscopic diverted sleeve gastrectomy with ileal transposition (DSIT) in patients with type 2 diabetes (T2DM). Methods A total of 360 patients with type 2 diabetes who underwent a DSIT procedure within the past 2-year period (2011–2013) were analyzed. Operation time, length of hospital stay, perioperative and postoperative complications, and mortality were recorded and analyzed. Results The participants consisted of 229 males (63.6 %) and 131 females (36.4 %). Mean duration of follow-up was 12.4 months (range, 6–31). One early and two late mortalities occurred. Early mortality was due to an anastomotic leak, and late mortalities were related to myocardial infarction and a traffic accident. Leakage and bleeding were the most common surgical complications. The total number of surgical complications was 22 (6.1 %). Of those, 19 occurred within the first month (early) and 3 occurred after the first month (late). Among early complications, seven (1.94 %) required re-operation, two patients (0.55 %) required endoscopic treatment, and the remaining ten were managed conservatively. Late surgical complications (sleeve angulation) were noted in three patients (0.83) and were treated by endoscopic stents. Surgery-related non-surgical complications occurred in 19 cases (5.2 %), and neurological complications were noted in 11 patients (3.05 %). Additional surgical intervention was required in 26 patients (7.22 %). Of those, 15 (4.16 %) required cholecystectomy. Conclusions Our data demonstrate that DSIT is a technically feasible operation and can be safely performed in type 2 diabetic patients with acceptable complication and mortality rates.

Abstract
Type 2 diabetes mellitus (T2DM) and obesity are increasingly common and major global health problems. The Edmonton obesity staging system clearly pointed towards increased mortality proportionate to the severity of obesity. Obesity itself triggers insulin resistance and thereby poses the risk of T2DM. Both obesity and T2DM have been associated with higher morbidity and mortality and this calls for institution of effective therapies to deal with the rising trend of complications arising out of this dual menace. Although lifestyle changes form the cornerstone of therapy for both the ailments, sustained results from this modalities is far from satisfactory. While Look AHEAD (action for HEAalth in diabetes) study showed significant weight loss, reduction in glycated hemoglobin and higher remission rate of T2DM at 1(st) year following intensive lifestyle measures; recurrence and relapse rate bounced back in half of subjects at 4 years, thereby indicating that weight loss and glycemic control is difficult to maintain in the long term with lifestyle interventions. Same recurrence phenomenon was also observed with pharmacotherapy with rimonabant, sibutramine and orlistat. Bariatric surgery has been seen to associate with substantial and sustained weight loss in morbidly obese patients. Interestingly, bariatric surgeries also induce higher rates of short and long-term diabetes remission. Although the exact mechanism behinds this diabetes remission are not well understood; improved insulin action, beta-cell function and complex interplay of hormones in the entero-insular axis appears to play a major role. This article reviews the effectiveness of bariatric procedures on remission or improvement in diabetes and put a perspective on its implicated mechanisms.

Abstract
Obesity and type 2 diabetes mellitus have been associated with higher morbidity and mortality. Bariatric surgery results in substantial and sustained weight loss in morbidly obese patients and improves obstructive sleep apnea. Furthermore, bariatric surgery improves diabetes control, hypertension, quality of life, stroke, myocardial infarction and reduces mortality. Interestingly, bariatric surgery induces high rates of short and long-term diabetes remission. While the exact mechanisms behind this are not completely understood, improved insulin action, β-cell function and a complex interplay of hormones in the entero-insular axis appear to play major roles. Insulin action improves proportionally to weight loss and it gets completely normalized especially after bilio-pancreatic diversion. β-Cell function also seems to improve after a variety of bariatric surgeries. Seemingly, baseline β-cell function is able to predict future diabetes remission. This article will review the effectiveness of bariatric procedures on the remission and improvement of diabetes and its implicated mechanisms.

Abstract
BACKGROUND DATA Bariatric/metabolic surgery has been proposed for the treatment of inadequately controlled type 2 diabetes mellitus (T2DM) in obese patients. However, prediction on successful long-term remission of T2DM after metabolic surgery has not been clearly studied. Our objectives were to evaluate rates of long-term remission of T2DM after metabolic surgery and determine the independent predictors of remission. METHODS Outcomes of 157 patients who underwent metabolic surgery between 2006 and 2009 and who had complete 5-year follow-up data were assessed. Prolonged complete remission was defined as glycated hemoglobin (HbA1c) less than 6 % without diabetes medication up to 5 years. Predictors of prolonged remission studies included patient characteristics such as glucose level, HbA1c, body weight, waist circumference, blood pressure, total cholesterol, LDL, triglyceride, uric acid, AST, alanine transaminase (ALT), albumin, insulin, C-peptide, iron, calcium, complete blood cell count, the ABCD score (a multidimensional grading system composed of age, body mass index (BMI), C-peptide levels, and duration of T2DM), and postoperative weight loss. RESULTS At 5 years after surgery, the weight loss was 27.1 % and the mean BMI decreased from 39.8 to 28.8 kg/m(2). The mean HbA1c decreased from 8.3 to 6.0 %. A significant number of patients had improvement in their glycemic control, including 97 (71.3 %) patients who had complete remission (HbA1c < 6.0 %), 27 (19.9 %) partial remission (HbA1c < 6.5 %), and 12 (8.8 %) improved condition (HbA1c < 7 %). In univariate analysis, patients with prolonged T2DM remission after surgery were younger and heavier; had a wider waist, higher C-peptide, shorter duration of T2DM, higher liver enzyme, higher insulin resistance, higher C-peptide level, and higher white blood cell count; were taking smaller insulin dosage; had higher ABCD score; and had greater weight loss than those without remission. Multivariate logistical regression analyses showed that the ABCD score and weight loss were the only predictors of remission after metabolic surgery. CONCLUSIONS Metabolic surgery is a treatment option for patients with obesity and T2DM. Baseline ABCD score and weight loss have a major influence on outcome.

Abstract
Metabolic surgery has been shown to provide better glycemic control for type 2 diabetes than conventional therapies. Still, the outcomes of the surgery are variable, and prognostic markers reflecting the metabolic changes by the surgery are yet to be established. NMR-based plasma metabolomics followed by multivariate regression was used to test the correlation between the metabolomic profile at 7-days after surgery and glycated hemoglobin (HbA1c) levels at 3-months (and up to 12 months with less patients), and to identify the relevant markers. Metabolomic profiles at 7-days could differentiate the patients according to the HbA1c improvement status at 3-months. The HbA1c values were predicted based on the metabolomics profile with partial least square regression, and found to be correlated with the observed values. Metabolite analysis suggested that 3-Hydroxybutyrate (3-HB) and glucose contributes to this prediction, and the [3-HB]/[glucose] exhibited a modest to good correlation with the HbA1c level at 3-months. The prediction of 3-month HbA1c using 7-day metabolomic profile and the suggested new criterion [3-HB]/[glucose] could augment current prognostic modalities and help clinicians decide if drug therapy is necessary.

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
BACKGROUND Metabolic surgery can modulate weight as well as food intake and basal energy expenditure. In this study, we evaluate the effectiveness of duodenal exclusion by analysing anthropometric results, intake variations, food behaviour and calorimetric parameters. METHODS This is an experimental study with 8-week-old Sprague-Dawley male rats. The sequences used are as follows: Cafeteria diet for 3 weeks, followed by surgery and sacrifice at 4 weeks. Four experimental groups are as follows: two non-obese groups (n = 15; surgery = 10, sham = 5) and two obese groups by cafeteria diet (n = 15; surgery = 10, sham = 5). Surgery performed was duodenal exclusion with physical barrier. Weight, intake, glycaemia and basal energy expenditure by indirect calorimetry were monitored before and after surgery. RESULTS Weight changes in groups that underwent intervention were significant. The reduction in calorie consumption after surgery was significant in the obese intervention group despite an increased standard feed consumption (161 ± 11 vs 139 ± 13 Kcal/day, p < 0.05; due to a lower consumption of cafeteria diet). In non-obese animals, changes were transient. Basal energy expenditure decreased in both intervention groups: 6.2 ± 0.5 vs 5.5 ± 0.4 Kcal/kg/h in non-obese animals and 5.6 ± 0.3 vs 4.7 ± 0.3 Kcal/kg/h in obese animals (p < 0.05). CONCLUSIONS Duodeno-jejunal tube placement stops weight gain in obese and non-obese animals. In obese animals, there is an important qualitative change in appetite towards standard feed with a significant decrease in caloric intake. In non-obese animals, changes in quantitative intake are transient. This surgery decreases basal energy expenditure in obese animals. This may be attributed to an enhanced thermogenic effect of food and a slowing in the animal's weight gain.

Abstract
AIM To investigate the short-term effect of ileal interposition (IT) surgery on gut morphology and enteroendocrine cell numbers in the pre-diabetic UC Davis type 2 diabetes mellitus (UCD-T2DM) rat. STUDY DESIGN Two-month old male UCD-T2DM rats underwent either sham (n=5) or IT (n=5) surgery. Intestines were collected 1.5months after surgery. The jejunum, ileum and colon regions were processed for histochemical and immunohistochemical labeling and stereological analyses of changes in gut morphometry and number of enteroendocrine cells. RESULTS Stereological analysis showed that intestinal volume, luminal surface area and the number of all chromogranin A-positive enteroendocrine cells were markedly increased in the IT rats compared with sham-operated animals. Subanalyses of the glucagon-like peptide 2, cholecystokinin, serotonin cells and the neurotensin immunoreactive sub-pool of enteroendocrine cells in the IT region revealed an increase in numbers across phenotypes. However, the density of the different cell types varied. CONCLUSION IT surgery in the UCD-T2DM rat leads to rapid alterations in gut morphometry and an increase in the number of enteroendocrine cells. This effect may potentially explain why IT surgery delays the onset of type 2 diabetes in the UCD-T2DM rat.

Abstract
OBJECTIVE Surprisingly, 40% to 95% of patients with type 2 diabetes mellitus (T2DM) show early remission of hyperglycemia after obesity surgery. It is unknown to what extent other diabetes-associated comorbidities such as distal peripheral neuropathy (DPN) might be influenced by obesity surgery. This pilot study aimed at providing further evidence for the impact of Roux-en-Y gastric bypass (RYGB) on both glycemic control and DPN in non-severely obese patients with insulin-dependent T2DM. METHODS In the present prospective cohort study, 20 patients with long-standing, insulin-dependent T2DM and a body mass index (BMI) between 25 and 35 kg/m underwent laparoscopic RYGB. Body mass index, glycosylated hemoglobin (HbA1c), and DPN [quantified by the Neuropathy Symptom Score (NSS) and the Neuropathy Deficit Score (NDS)] were investigated. RESULTS Six months after surgery, the preoperative BMI of 32.8 ± 2.1 kg/m (mean ± standard deviation) dropped to 25.6 ± 2.5 kg/m (P < 0.001). Preoperative HbA1c levels decreased from 8.5 ± 1.2% to 7.1 ± 1.2% (P < 0.001), with 15% of patients having a normalized HbA1c level lower than 6.2%. Of 12 patients with documented DPN, the median NSS was 8 (range, 0-10) preoperatively and 0 (range, 0-9) postoperatively (P = 0.004), with 8 patients scoring an NSS of 0. The median NDS was 6 (range, 2-8) preoperatively and 4 (range, 0-8) postoperatively (P = 0.027), with 1 patient scoring an NDS of 0. All patients had an improvement or normalization in either 1 or both scores. CONCLUSIONS As expected, BMI and HbA1c levels improved significantly after RYGB. More interestingly, neuropathy scores, such as NSS and NDS, improved significantly early after surgery. Symptomatic neuropathy was completely reversible in 67% of the patients. These findings add further evidence to the fact that RYGB might be a valuable treatment option not only for improving glycemic control but also for reducing diabetes-associated comorbidities, such as DPN. This points to a complex metabolic effect of RYGB that exceeds glucose normalization. However, the results still need to be confirmed in controlled trials.

Abstract
BACKGROUND Obesity is associated with abnormal fasting and postprandial lipids, which may link obesity with atherosclerosis. We explored fasting and postprandial lipids in morbidly obese patients treated with sleeve gastrectomy and in control subjects. METHODS After fasting for 12 h 15 morbidly obese patients (BMI 51.4±6.5 kg/m2, 43.7±12.6 years) received a standardized oral fat load before and 3 months after bariatric surgery (sleeve gastrectomy). Controls (n=9, BMI 23.1±1.4 kg/m²) were studied once. Plasma was obtained fasting and then postprandially every 2 h for 8 h. Triglycerides (TG), chylomicron-TG (CM-TG), VLDL/chylomicron-remnant (VLDL/CR)-TG, cholesterol, LDL-cholesterol, VLDL/CR-cholesterol and HDL-cholesterol were isolated by ultracentrifugation at each time point. Postprandial values were expressed as area under the curve (AUC) and incremental area under the curve (iAUC). In addition, fasting glucose and insulin values and HOMA-IR-Index was measured (n=14). RESULTS Compared to controls morbidly obese patients had elevated TG and slightly altered postprandial lipids. Following surgery (weight loss 23.4 kg±6.2 kg; p<0.001) fasting TG (-19.1%; p=0.04), VLDL/CR-TG (-20.0%; p=0.05) decreased significantly, while fasting cholesterol, VLDL-, HDL- and LDL-cholesterol did not change. AUC and iAUC decreased significantly for VLDL/CR-TG (-20.4%, p=0.04 and -38.5%, p=0.04, respectively). Neither fasting nor postprandial changes correlated with the change in weight. In patients with preoperatively elevated TG (>150 mg/dl) a similar pattern was observed. Fasting insulin and HOMA were reduced significantly (-51.9%; p=0.004 and -47.9%; p=0.011). CONCLUSIONS Three months after sleeve gastrectomy fasting and postprandial lipoprotein metabolism and glucose metabolism is improved in morbidly obese patients. The potential mechanisms may relate to decreased caloric intake but also to hormonal changes.

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
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.

Abstract
Bariatric surgery has been used to treat type 2 diabetes mellitus (T2DM); however, its efficacy is still debatable. This literature review analyzed articles that evaluated the effects of bariatric surgery in treatment of T2DM in obese patients with a body mass index (BMI) of <35 kg/m(2). A paired t test was applied for the analysis of pre- and postintervention mean BMI, fasting plasma glucose (FPG), and glycosylated hemoglobin (A1c) values. A significant (P<0.001) reduction in BMI (from 29.95±0.51 kg/m(2) to 24.83±0.44 kg/m(2)), FPG (from 207.86±8.51 mg/dL to 113.54±4.93 mg/dL), and A1c (from 8.89±0.15% to 6.35±0.18%) was observed in 29 articles (n=675). T2DM resolution (A1c <7% without antidiabetes medication) was achieved in 84.0% (n=567) of the subjects. T2DM remission, control, and improvement were observed in 55.41%, 28.59%, and 14.37%, respectively. Only 1.63% (n=11) of the subjects presented similar or worse glycemic control after the surgery. T2DM remission (A1c <6% without antidiabetes medication) was higher after mini-gastric bypass (72.22%) and laparoscopic/Roux-en-Y gastric bypass (70.43%). According to the Foregut and Hindgut Hypotheses, T2DM results from the imbalance between the incretins and diabetogenic signals. The procedures that remove the proximal intestine and do ileal transposition contribute to the increase of glucagon-like peptide-1 levels and improvement of insulin sensitivity. These findings provide preliminary evidence of the benefits of bariatric-metabolic surgery on glycemic control of T2DM obese subjects with a BMI of <35 kg/m(2). However, more clinical trials are needed to investigate the metabolic effects of bariatric surgery in T2DM remission on pre-obese and obese class I patients.

Abstract
BACKGROUND Ileal interposition (IT), in which the distal ileum is transposed isoperistaltically into the proximal jejunum, is considered as a procedure for metabolic or antidiabetes surgery. Our aim was to study the effects of IT on glycemic control, fat metabolism, and hormonal changes in obese rats with spontaneous diabetes. METHODS Animals were divided into either an IT or a sham (SH) group. They underwent an oral glucose tolerance test (OGTT) before and 4 and 8 weeks after the operation. All animals were killed 10 weeks after operation for analyses of tissue weight (liver, pancreas, epididymal fat, brown fat), immunoblotting of uncoupling protein-1 (UCP1) protein in brown adipose tissue (BAT), and fasting plasma levels of glucose, insulin, glucagon-like peptide (GLP)-1, peptide YY (PYY), glucose-dependent insulinotropic polypeptide (GIP), and leptin. RESULTS Body weight increased postoperatively in both groups compared with preoperative weight, but it did not differ between the 2 groups. Eight weeks postoperatively, integrated blood glucose levels during the OGTT were decreased in IT compared with SH (P < .05). Fasting plasma levels of insulin, GLP-1, and GIP did not differ between the 2 groups, but PYY levels were higher in the IT animals (P < .01). The weight of epididymal and BATs, homeostasis model assessment insulin resistance, and fasting plasma leptin levels were decreased in the IT group (P < .05). Expression of UCP1 was higher in IT than SH animals (P < .05). CONCLUSION These results suggest that IT improves glucose and lipid metabolism by decreasing insulin resistance and epididymal fat, and increased expression of UCP1 in BAT might be among the mechanisms responsible.

Abstract
BACKGROUND Standard surgical procedures used for the treatment of morbid obesity constitute optional treatments for type 2 diabetes mellitus (T2DM). The aim of the present study was to evaluate the short- and mid-term effects of laparoscopic sleeve gastrectomy (SG) with ileal interposition (II) in T2DM patients (n = 30). METHODS The variables investigated were the feasibility of the procedure, remission/alleviation of the disease, morbidity, mortality, and weight loss. Patients were followed during a period of 6-18 months after surgery. RESULTS The average time required for the surgical procedure was 181.47 ± 53.23 min, and the mean duration of postoperative hospital stay was 3.17 ± 0.79 days. There were no intraoperative complications, and none of the patients required conversion to open surgery. Postoperatively, all patients experienced a significant weight loss: i.e., the mean body mass index (BMI) values prior to and following surgery were significantly different (P = 0.0001). Postoperative levels of glycosylated hemoglobin, fasting glucose, and fructosamine were significantly reduced (P = 0.0001, 0.0001, and 0.0004, respectively) from those detected prior to surgery. Remission of T2DM was observed in 80% of the patients over the follow-up period, and these subjects no longer required treatment with hypoglycemic drugs or diet. The remaining 20% of patients presented significant improvement in their condition but needed an oral hypoglycemic medication. CONCLUSIONS Adequate glycemic control, adjustable weight loss, and absence of nutritional deficiencies were the main benefits offered by the surgical intervention. The results indicate that SG/II treatment could be a promising alternative for patients with T2DM.

Abstract
The aim of this study was to evaluate the mid-term outcomes of the laparoscopic ileal interposition associated to a sleeve gastrectomy (LII-SG) for the treatment of morbid obesity. The procedure was performed in 120 patients: 71 women and 49 men with mean age of 41.4 years. Mean body mass index (BMI) was 43.4 ± 4.2 kg/m². Patients had to meet requirements of the 1991 NIH conference criteria for bariatric operations. Associated comorbidities were observed in all patients, including dyslipidemia in 51.7%, hypertension in 35.8%, type 2 diabetes in 15.8%, degenerative joint disease in 55%, gastroesophageal reflux disease in 36.7%, sleep apnea in 10%, and cardiovascular problems in 5.8%. Mean follow-up was 38.4 ± 10.2 months, range 25.2-61.1. There was no conversion to open surgery nor operative mortality. Early major complications were diagnosed in five patients (4.2%). Postoperatively, 118 patients were evaluated. Late major complications were observed in seven patients (5.9%). Reoperations were performed in six (5.1%). Mean postoperative BMI was 25.7 ± 3.17 kg/m², and 86.4% were no longer obese. Mean %EWL was 84.5 ± 19.5%. Hypertension was resolved in 88.4% of the patients, dyslipidemia in 82.3%, and T2DM in 84.2%. The LII-SG provided an adequate weight loss and resolution of associated diseases during mid-term outcomes evaluation. There was an acceptable morbidity with no operative mortality. It seems that chronic ileal brake activation determined sustained reduced food intake and increased satiety over time. LII-SG could be regularly used as a surgical alternative for the treatment of morbid obesity.

Abstract
INTRODUCTION Bariatric surgery in morbidly obese type 2 diabetic (T2DM) patients is associated with high rates of diabetes remission. We investigated the mechanisms of the anti-diabetic effect of the laparoscopic ileal interposition with sleeve gastrectomy (LII-SG) in normal weight (NW), overweight (OW) and obese (OB) T2DM patients. METHODS Ninety-four patients (aged 54 ± 8 years) with long-standing (median 10 years), treated diabetes (median HbA(1c) = 8.6%), who were NW (15), OW (64) or OB (15) based on BMI, underwent LII-SG. Insulin sensitivity and parameters of ß-cell function were measured from an Oral Glycaemic Tolerance Test pre- and post-operatively. RESULTS At a median of 13.4 months post-operatively, weight loss averaged 9.4 ± 1.3, 16.8 ± 0.8 and 23.2 ± 1.7 kg in NW, OW and OB subjects, respectively (p < 0.0001). Insulin sensitivity was fully restored (395 [108] vs 208 [99] ml min⁻¹ m⁻²), fasting insulin secretion rate decreased (68 [52] vs 146 [120] pmol min⁻¹ m⁻²) and total insulin output increased (52 [26] vs 39 [28] nmol m⁻², all p ≤ 0.001). ß-cell glucose sensitivity doubled (37 [33] vs 18 [24] mol min⁻¹ m⁻² mM⁻¹, p < 0.0001). The only parameter predicting remission of diabetes was a lower baseline insulin sensitivity (p = 0.005). CONCLUSIONS LII-SG induced changes on T2DM by mechanisms in part distinct from weight loss, principally involving restoration of insulin sensitivity and improvement of ß-cell function.

Abstract
BACKGROUND The objective of this study was to evaluate the early results of the laparoscopic interposition of a segment of ileum associated with a sleeve gastrectomy (LII-SG) in order to treat patients with type 2 diabetes mellitus (T2DM) and BMI <35. Data regarding morbidly obese diabetic patients subjected to surgery has consistently been validated. To date, there is scarce information about morbidity and mortality related to the surgical treatment of a "true" typical diabetic population with BMI <35. METHODS The procedures were performed in 454 patients (322 male, 132 female). Mean age was 53.6 ± 8 years (range = 27-75). Mean BMI was 29.7 ± 3.6 kg/m(2) (range = 19-34.8). All patients had the diagnosis of T2DM for at least 3 years. Insulin therapy was used by 45.6% of patients. Mean duration of T2DM was 10.8 ± 5.9 years (range = 3-35). Mean hemoglobin A(1c) was 8.8 ± 1.9%. Dyslipidemia was observed in 78.4%, hypertension in 64.8%, nephropathy in 28.6%, retinopathy in 32.6%, neuropathy in 34.6%, and coronary heart disease in 13%. RESULTS There was no conversion to open surgery. All patients were evaluated postoperatively. Mortality was 0.4%. There were 29 major complications (6.4%) in 22 patients (4.8%) and 51 minor complications (11.2%). Reoperations were performed on 8 patients (1.7%). Twenty patients (4.4%) were readmitted to the hospital. Mean postoperative BMI was 25.8 ± 3.5 kg/m(2). Mean fasting plasma glucose decreased from 198 ± 69 to 128 ± 67 mg/dl and mean postprandial plasma glucose decreased from 262 ± 101 to 136 ± 43 mg/dl. CONCLUSIONS The laparoscopic ileal interposition associated with a sleeve gastrectomy was considered a safe operation with low rates of morbidity and mortality in a diabetic population with BMI < 35. An early control of postprandial glycemia was observed.

Abstract
The global prevalence of type 2 diabetes mellitus and impaired glucose metabolism continues to rise in conjunction with the pandemic of obesity. The metabolic Roux-en-Y gastric bypass operation offers the successful resolution of diabetes in addition to sustained weight loss and excellent long-term outcomes in morbidly obese individuals. The procedure consists of the physiological BRAVE effects: (i) Bile flow alteration; (ii) Reduction of gastric size; (iii) Anatomical gut rearrangement and altered flow of nutrients; (iv) Vagal manipulation and (v) Enteric gut hormone modulation. This operation provides anti-diabetic effects through decreasing insulin resistance and increasing the efficiency of insulin secretion. These metabolic outcomes are achieved through weight-independent and weight-dependent mechanisms. These include the foregut, midgut and hindgut mechanisms, decreased inflammation, fat, adipokine and bile metabolism, metabolic modulation, shifts in gut microbial composition and intestinal gluconeogenesis. In a small minority of patients, gastric bypass results in hyperinsulinaemic hypoglycaemia that may lead to nesidioblastosis (pancreatic beta-cell hypertrophy with islet hyperplasia). Elucidating the precise metabolic mechanisms of diabetes resolution and hyperinsulinaemia after surgery can lead to improved operations and disease-specific procedures including 'diabetes surgery'. It can also improve our understanding of diabetes pathogenesis that may provide novel strategies for the management of metabolic syndrome and impaired glucose metabolism.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) surgery is one of the most effective treatments for obesity producing long-term weight loss. The anorexia and weight loss from RYGB could be due to gastric restriction, malabsorption, enhanced lower gut stimulation, increased energy expenditure, and/or other metabolic adaptations. In ileal transposition (IT) surgery, a segment of the ileum is transposed to the upper jejunum with no gastric restriction or malabsorption. Our objective is to compare the effects of RYGB and IT surgeries on food intake, body weight, and plasma concentrations of the anorexigenic lower gut hormone Peptide YY (PYY) in rats. METHODS Adult male Sprague-Dawley rats were subjected to either RYGB (n = 9), IT (n = 9) or sham surgeries (n = 16). A subset of sham animals were either pair-fed to RYGB (n = 9) or ad lib fed (n = 7) on a highly palatable mixed nutrient liquid food (Ensure). Food intake, body weight and plasma PYY concentrations were measured. RESULTS The data demonstrate that (1) RYGB produces a sustained reduction in food intake and weight gain, (2) the anorexic effects of IT are relatively transient lasting for 5 weeks, (3) the reduction in weight gain resulting from IT is similar to that of animals pair-fed to RYGB, and (4) RYGB and IT surgeries are associated with elevated postprandial plasma PYY concentrations. CONCLUSIONS We demonstrate in our rat models that RYGB surgery produces a greater reduction in food intake and weight gain than IT surgery, and that both surgeries are associated with enhanced plasma concentrations of Peptide YY.

Abstract
The hindgut hypothesis posits improvements in Type 2 diabetes after gastric bypass surgery are due to enhanced delivery of undigested nutrients to the ileum, which increase incretin production and insulin sensitivity. The present study investigates the effect of ileal interposition (IT), surgically relocating a segment of distal ileum to the proximal jejunum, on glucose tolerance, insulin sensitivity, and glucose transport in the obese Zucker rat. Two groups of obese Zucker rats were studied: IT and sham surgery ad libitum fed (controls). Changes in food intake, body weight and composition, glucose tolerance, insulin sensitivity and tissue glucose uptake, and insulin signaling as well as plasma concentrations of glucagon-like peptide-1 and glucose-dependent insulinotropic peptide were measured. The IT procedure did not significantly alter food intake, body weight, or composition. Obese Zucker rats demonstrated improved glucose tolerance 3 wk after IT compared with the control group (P < 0.05). Euglycemic, hyperinsulinemic clamp and 1-[(14)C]-2-deoxyglucose tracer studies indicate that IT improves whole body glucose disposal, insulin-stimulated glucose uptake, and the ratio of phospho- to total Akt (P < 0.01 vs. control) in striated muscle. After oral glucose, the plasma concentration of glucagon-like peptide-1 was increased, whereas GIP was decreased following IT. Enhanced nutrient delivery to the ileum after IT improves glucose tolerance, insulin sensitivity and muscle glucose uptake without altering food intake, body weight, or composition. These findings support the concept that anatomic and endocrine alterations in gut function play a role in the improvements in glucose homeostasis after the IT procedure.

Abstract
BACKGROUND Existing evidence has suggested that bariatric surgery produces sustainable weight loss and remission or cure of type 2 diabetes mellitus (DM). Laparoscopic sleeve gastrectomy (LSG) has garnered considerable interest as a low morbidity bariatric surgical procedure that leads to effective weight loss and control of co-morbid disease. The objective of the present study was to systematically review the effect of LSG on type 2 DM. METHODS An electronic data search of MEDLINE, PubMed, Embase, Scopus, Dare, Clinical Evidence, TRIP, Health Technology Database, Conference abstracts, clinical trials, and the Cochrane Library database was completed. The search terms used included LSG, vertical gastrectomy, bariatric surgery, metabolic surgery, and diabetes (DM), type 2 DM, or co-morbidities. All human studies, not limited to those in the English language, that had been reported from 2000 to April 2010 were included. RESULTS After an initial screen of 3621 titles, 289 abstracts were reviewed, and 28 studies met the inclusion criteria and the full report was assessed. One study was excluded after a careful assessment because the investigators had combined LSG with ileal interposition. A total of 27 studies and 673 patients were analyzed. The baseline mean body mass index for the 673 patients was 47.4 kg/m(2) (range 31.0-53.5). The mean percentage of excess weight loss was 47.3% (range 6.3-74.6%), with a mean follow-up of 13.1 months (range 3-36). DM had resolved in 66.2% of the patients, improved in 26.9%, and remained stable in 13.1%. The mean decrease in blood glucose and hemoglobin A1c after sleeve gastrectomy was -88.2 mg/dL and -1.7%, respectively. CONCLUSION Most patients with type 2 DM experienced resolution or improvement in DM markers after LSG. LSG might play an important role as a metabolic therapy for patients with type 2 DM.

Abstract
BACKGROUND Dyslipidemia is known to increase significantly the odds of major cardiovascular events in the general population. Its control becomes even more important in the type 2 diabetic (T2DM) population. Bariatric surgeries, especially gastric bypass, are effective in achieving long-term control of dyslipidemia in morbidly obese patients. OBJECTIVE The objective of the study was to evaluate the control of dyslipidemia in patients with T2DM and BMI below 30 that were submitted to the laparoscopic ileal interposition associated to sleeve gastrectomy. METHODS An observational transversal study was performed in a tertiary care hospital, between June 2005 and August 2007. Mean follow-up was 24.5 months (range 12-38). The procedure was performed in 72 patients: 51 were men and 21 were women. Mean age was 53.1 years (38-66). Mean BMI was 27 kg/m(2) (22.1-29.4). Mean duration of T2DM was 10.5 years (3-22). Mean HbA1c was 8.5%. Hypercholesterolemia was diagnosed in 68% of the patients and hypertriglyceridemia in 63.9%. RESULTS Mean postoperative BMI was 21.2.kg/m(2) (17-26.7). Mean postoperative HbA1c was 6.1%, ranging 4.4% to 8.3%. Overall, 86.1% of the patients achieved an adequate glycemic control (HbA1c < 7) without anti-diabetic medication. HbA1c below 6 was achieved by 50%, 36.1% had HbA1c between 6 and 7, and 13.9% had HbA1c above 7. Total hypercholesterolemia was normalized in 91.8% and hypertriglyceridemia in 89.1% of patients. Low-density lipoprotein below 100 mg/dl was seen in 85.7%. CONCLUSIONS The laparoscopic ileal interposition associated to sleeve gastrectomy was an effective operation for the regression of dyslipidemia and T2DM in a non-obese population.

Abstract
Obesity and related metabolic disorders are increasing especially in developing countries. It is widely accepted that in extremely obese patients bariatric surgery reduces body weight and improves type 2 diabetes and the metabolic syndrome. Weight loss partially explains this effect as do weight loss-independent mechanisms linked to gut hormones, peptide YY, ghrelin, glucagon-like peptide-1, and glucose-dependent insulinotropic peptide/gastric inhibitory polypeptide. Several groups performing established and novel surgical techniques have shown encouraging metabolic results. Herein we consider whether it is theoretically plausible to use surgery as an alternative or complementary approach to medical treatment of diabetes in overweight and mildly obese patients.

Abstract
BACKGROUND Foregut diversion and weight loss have been proposed as potential mechanisms for resolution of type II diabetes mellitus (T2DM) observed in patients undergoing gastric bypass for obesity. To support or refute the role of the foregut, we analyzed glycemic control in T2DM patients before and after foregut bypass for reasons other than morbid obesity. STUDY DESIGN Using ICD9/CPT codes, we identified patients undergoing Roux-en-Y gastrojejunostomy (RY) or Billroth II (BII) reconstruction over 10 years. Fasting blood glucose, insulin or oral diabetic agent requirement, and body mass index (BMI) before and after surgery were tabulated and compared using the Student's t-test. Linear regression was applied to determine specific factors predictive of resolution or improvement in glycemic control including age, duration of diabetes, antidiabetic regimen, type of operation, and surgical indication. RESULTS Between 1996 and 2006, we identified 24 patients with T2DM out of a cohort of 209 who underwent either RY (12 of 24) or BII reconstruction (12 of 24) for cancer or peptic ulcer disease and survived more than 30 days after operation. Of this group, 75% were overweight (18 of 24 with BMI < 30 kg/m(2)) and 25% were class I morbidly obese (6 of 24 with BMI 30 to 35 kg/m(2)). Seventeen patients (71%) had either complete resolution (7 of 24 or 29%) or significant reduction (10 of 24 or 42%) in medication requirements; 7 patients (29%) did not have any improvement. Logistic regression failed to identify specific factors predicting improved glycemic control. CONCLUSIONS Complete resolution of T2DM in patients undergoing duodenal diverting surgery occurs in about one-third of nonobese patients. Improved glycemic control occurs in more than two-thirds and cannot be explained by surgically related weight loss alone. Surgical cure of T2DM may be possible in carefully selected nonobese patients.

Abstract
BACKGROUND The sleeve gastrectomy is a surgical technique to treat morbid obesity by both restrictive and probably hormonal action. Originally developed as a first stage to gastric bypass, it is more and more performed as a sole procedure. Therefore it is important to report results on weight loss and reduction in co-morbidity. METHODS A consecutive series of 74 morbid obese patients were evaluated. Parameters were operative variables, complications, weight loss and the need for medication for co-morbidity at least six months postoperatively. RESULTS Six procedures included the removal of a band and twice a vertical banded gastroplasty was performed previously. Median operating time diminished over time to 71 min. Three procedures were converted into open approach. Major complications were rhabdomyolysis (2), bleeding (2) and leakage (4). Four days was the mean hospital stay. The median follow-up was 12 months (range 6-33). The median percentage of excess weight loss was 49.6% (range 22-96%EWL). The median loss in BMI points was 23.1% (range 9-50%BMIL). Three quarters of the patients were able to diminish or stop their medication for diabetes, hypertension and hyperlipedemia. CONCLUSION The laparoscopic gastric sleeve is effective in reduction of both weight and co-morbidity and has potential as a sole procedure. Patient's selection is, however, recommendable for initial surgical experience and longer follow-up will be necessary.

Abstract
Resolution of Type-2 diabetes mellitus (DM) after weight loss surgery is well documented, but the mechanism is elusive. We evaluated the glucose-insulin metabolism of patients undergoing a Roux-en-Y gastric bypass (RYGB) using the intravenous glucose tolerance test (IVGTT) and compared it with patients who underwent laparoscopic adjustable gastric band (AB) placement. Thirty-one female patients (age range, 20 to 50 years; body mass index, 47.2 kg/m2) underwent RYGB. Nine female patients underwent AB placement and served as control subjects. All patients underwent IVGTT at baseline and 1 month and 6 months after surgery. Thirteen patients undergoing RYGB and one patient undergoing AB exhibited impaired glucose tolerance or DM defined by the American Diabetes Association. By 6 months post surgery, diabetes was resolved in all but one patient undergoing RYGB but not in the patient undergoing AB. Patients with diabetes undergoing RYGB demonstrated increased insulin secretion and β-cell responsiveness 1 month after surgery and continued this trend up to 6 months, whereas none of the patients undergoing AB had changes in β-cell function. Both patients undergoing RYGB and those undergoing AB demonstrated significant weight loss (34.6 and 35.0 kg/m2, respectively) and improved insulin sensitivity at 6 months. RYGB ameliorates DM resolution in two phases: 1) early augmentation of beta cell function at 1 month; and 2) attenuation of peripheral insulin resistance at 6 months. Patients undergoing AB only exhibited reduction in peripheral insulin resistance at 6 months but no changes in insulin secretion.

[The effects of ileal transposition, gastrojejunal bypass and vertical gastroplasty on the regulation of ingestion in an experimental obesity model associated with diabetes mellitus type 2]. Cir Esp 2009; 85:222-8. [PMID: 19327756 DOI: 10.1016/j.ciresp.2008.10.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2008] [Accepted: 10/24/2008] [Indexed: 11/30/2022]
Abstract
AIM The continual advances in our knowledge of the pathogenesis and hormonal disorders of morbid obesity lead to new studies in experimental animals and the development of new technical options. The aim is to asses whether ileal transposition can be a good treatment of morbid obesity associated with diabetes mellitus due to the action of intestinal peptide Glp-1 (enteroglucagon) compared to gastric bypass and vertical gastroplasty (VGB). MATERIAL AND METHODS Trial environment: experimental animals ZDF rats (Zucker Diabetic Fatty rats). Subjects of the study: three groups of 10 animals each one divided as: a) ileal tranposition; b) gastro-jejunal bypass; c) vertical gastroplasty. Parameters to determine: weight loss, levels of glycaemia, enteroglucagon, insulin and ghrelin in blood, one week before the operation as a baseline control, and 15 days after the surgical procedure. RESULTS Gastrojejunal bypass produces the most significant weight loss. There is a significant decrease in intake in all groups. Hyperinsulinaemia and hyperglycaemia tend to decrease after surgery in all groups, but in ileal transposition there is better control of ketosis. After gastrojejunal bypass and ileal transposition, we observed an increase in GLP-1 levels but were only significant in ileal transposition. CONCLUSIONS Ileal transposition produces a decrease in plasma glucose and better control of diabetes mellitus, which could benefit patients affected by morbid obesity and poor metabolic control. More studies are needed on other models of obesity. A model of exogenous and reversible obesity could be a good option to study the real benefits of the interventions.

Laparoscopic ileal interposition associated to a diverted sleeve gastrectomy is an effective operation for the treatment of type 2 diabetes mellitus patients with BMI 21-29. Surg Endosc 2008; 23:1313-20. [PMID: 18830750 DOI: 10.1007/s00464-008-0156-x] [Citation(s) in RCA: 78] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2008] [Revised: 07/29/2008] [Accepted: 08/13/2008] [Indexed: 12/18/2022]
Abstract
BACKGROUND The objective of this study is to evaluate the clinical results of the laparoscopic interposition of a segment of ileum into the proximal duodenum associated to a sleeve gastrectomy (II-DSG) in order to treat patients with type 2 diabetes mellitus (T2DM) and body mass index (BMI) 21-29 kg/m2. PATIENTS AND METHODS The laparoscopic procedure was performed in 69 patients, 22 female and 47 male. Mean age was 51 years (range 41-63 years). Mean BMI was 25.7 (21.8-29.2) kg/m2. All patients had the diagnosis of T2DM for at least 3 years and evidence of stable treatment with oral hypoglycemic agents and or insulin for at least 12 months. Insulin therapy was used by 44% of the patients. Mean duration of T2DM was 11 years (range 3-18 years). Dyslipidemia was diagnosed in 72.5% and hypertension in 66.7%. Nephropathy was characterized in 29% of the patients, retinopathy in 26.1%, and neuropathy in 24.6%. RESULTS Overall, 95.7% of the patients achieved adequate glycemic control (Hb(A1c) < 7%) without antidiabetic medication. Hb(A1c) below 6% was achieved by 65.2%. Mean postoperative follow-up was 21.7 months (range 7-42 months). Mean postoperative BMI was 21.8 kg/m2. There was no conversion to open surgery. Median hospital stay was 3.4 days (range 2-58 days). Major postoperative complications were diagnosed in 7.3%. There was no mortality. Fasting glycemia decreased from a mean of 218 to 102 mg/dl, postprandial glycemia from 305 to 141 mg/dl, and homeostasis model assessment of insulin resistance (Homa-IR) from 5.2 to 0.77. All associated comorbidities and complications related to T2DM had significant improvement or control. Arterial hypertension was controlled in 91.3%. Macroalbuminuria was no longer observed. Microalbuminuria resolved in 87.5% of patients. Hypercholesterolemia was normalized in 95% and hypertriglyceridemia in 92% of patients. CONCLUSIONS Laparoscopic II-DSG was an effective operation in controlling T2DM in a nonobese (BM < 30 kg/m2) population. Associated diseases and related complications were also improved. A longer follow-up period is needed.

Abstract
BACKGROUND A group of patients with type 2 diabetes mellitus (T2DM) and body mass index (BMI) 20-34 kg/m(2) were submitted to laparoscopic interposition of a segment of ileum into the proximal jejunum or into the proximal duodenum associated to a sleeve gastrectomy. The objective of this study is to evaluate the hormonal changes in the pre- and postoperative period. MATERIALS AND METHODS Hormonal evaluation was done in 58 patients operated between April 2005 and July 2006. Mean age was 51.4 years (40-66 years). Mean BMI was 28.2 (20-34.8) kg/m(2). All patients had had the diagnosis of T2DM for at least 3 years. Mean duration of T2DM was 9.6 years (3-22 years). Two techniques were performed, consisting of different combinations of ileal interposition (II) associated to a sleeve gastrectomy (SG). The following hormones were assayed in the pre- and postoperative period (mean 16 months) at the baseline and following specific food stimulation (30, 60, 120 min): glucogen-like protein 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), insulin, glucagon, C-peptide, amylin, cholecystokinin (CCK), pancreatic polypeptide (PPP), somatostatin, peptide YY (PYY), ghrelin, adiponectin, resistin, leptin, and interleukin-6 (IL-6). RESULTS Thirty patients had II associated to sleeve gastrectomy (II-SG) and 28 had II with diverted sleeve gastrectomy (II-DSG). GLP1 exhibited an important rise following the two operations, especially after II-DSG (p < 0.001). GIP also exhibited an important rise, with both II-SG and II-DSG being equally effective (p < 0.001). Insulin and amylin showed a significant rise at 30 min. Glucagon decreased slightly. CCK measurements were very low after II-DSG. PPP was also slightly altered by the II-DSG. PYY showed an important increase with both operations (p < 0.001). Ghrelin showed a significant decrease following the two operations (p < 0.001). Somatostatin and IL-6 were not affected (p = 0.632). Both leptin and resistin blood levels decreased. Adiponectin showed a slight increase. Mean postoperative follow-up was 19.2 months. Both II-SG and II-DSG were effective in achieving adequate glycemic control (91.2%). CONCLUSIONS There was a significant hormonal change following laparoscopic ileal interposition. These alterations may explain the promising good results associated to these operations for the treatment of T2DM in the nonmorbidly obese population.

Abstract
BACKGROUND Type 2 diabetes mellitus is a worldwide healthcare problem with major socioeconomic implications. Metabolic surgical procedures have been shown to improve diabetes, but the mechanism of action is poorly understood. The Goto-Kakizaki (GK) rodent is a type 2 diabetic animal model that is ideally situated for studying the effect of surgery on diabetes; however, the operative mortality is high. The aim of this study was to describe the operative technique, improvements in perioperative management, and the technique of micro-positron emission tomography (PET) scanning of the beta-cell mass in GK rodents. METHODS A total of 53 GK rats were divided into 1 of 3 operative groups: sham, sleeve gastrectomy, and duodenojejunal bypass. A subset of animals underwent micro-PET scanning with [11C]-dihydrotetrabenazine to determine the vesicular monoamine transporter 2 binding index, an indicator of beta-cell mass. RESULTS The 30-day mortality in the sham and sleeve gastrectomy rodents was 0; however, 2 sleeve gastrectomy rodents developed enterocutaneous fistula and 1 developed an abscess. In the duodenojejunal bypass group, the initial mortality rate was close to 90%; however, refinements in the surgical technique and perioperative management (fluids, antibiotics, pain control) lowered the mortality rate to 60%. The surgical technique is discussed in detail. [11C]-Dihydrotetrabenazine uptake in the pancreas was demonstrated on micro-PET scanning in the sham and duodenojejunal bypass rodents. CONCLUSION Intensive medical management in the perioperative period and attention to the operative technique lowered the mortality. [11C]-Dihydrotetrabenazine micro-PET scanning is a feasible method for assessing the beta-cell mass in GK rodents and could prove to be an important modality for evaluating beta-cell performance in type 2 diabetes.
