Obesity is a growingly impacting human health concern. Laparoscopic sleeve gastrectomy (LSG) is an effective treatment for morbid obesity. However, the general anesthesia (GA) used in this major surgery has its documented drawbacks in obese patients with high risk. On the other hand, combined thoracic spinal-epidural anesthesia (CTSEA), a modern regional anesthesia procedure, has the advantages of both spinal and epidural anesthesia but without their shortcomings. This prospective study is a case experience that assesses the feasibility of CTSEA as an anesthesia option for laparoscopic sleeve gastrectomy (LSG).
MethodsA total of 100 patients were recruited for LSG as a management procedure for morbid obesity, which was performed under CTSEA. Perioperative events, functional parameters, and patients’ satisfaction scores were recorded.
ResultsOur prospective study showed successful use of CTSEA in 99% of the patients, except for one patient (1%) in whom CTSEA was converted into GA due to severe pain and anxiety. Few adverse events occurred and were managed accordingly. The satisfaction score revealed that 94% of the patients were satisfied.
ConclusionsCTSEA was a successful anesthetic alternative procedure for LSG surgery.
Graphical abstract 相似文献The demand for revisional bariatric surgery after sleeve gastrectomy (SG) has increased, but the ideal procedure remains unclear. A systematic review and meta-analysis were performed to compare the outcomes of weight loss and safety of one-anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) as revisional procedures for failed SG. Four retrospective comparative studies were included, comprising 499 individuals. Patients submitted to OAGB had a more significant total weight loss (TWL) (MD = − 5.89%; 95% CI − 6.80 to − 4.97) after revisional surgery. Overall early complication rate was similar between procedures (RD = 0.04; 95% CI: − 0.05 to 0.12). Limited and heterogeneous data prevent meaningful conclusions, but the present analysis suggests that OAGB has a better TWL after revisional surgery.
Graphical abstract 相似文献Fatty acids (FA), particularly polyunsaturated (PUFA) ones, are involved in the regulation of glycemic control, lipid metabolism, and inflammation. The aim of the study was to assess patient FA profile in relation to obesity, lipid and carbohydrate metabolism disturbances, and weight loss.
Materials and MethodsThe studied group consisted of 51 patients with extreme obesity, 23 of whom achieved radical weight reduction within 1 year after a laparoscopic sleeve gastrectomy (LSG). FA levels were determined using gas chromatography with flame ionization detection.
ResultsPatients with extreme obesity and higher serum PUFA content have lower serum levels of SFA and MUFA (especially myristic, palmitic, lignoceric acids and palmitoleic, oleic acids), as well as lower triglyceride and higher HDL-cholesterol concentrations and it was not influenced by CEPT Taq1B variant. At baseline, the fatty acid profile of patients with type II diabetes differ from patients with dyslipidemia. In patients who had lost weight, significantly lower levels of selected saturated FA and major trans-fatty acid, elaidic, were found. Moreover, the proportion of PUFA was increased.
ConclusionIn extreme obesity, higher PUFA exert their favorable effects on serum lipids. Significant weight reduction after the bariatric surgery is associated with beneficial changes in the fatty acid profile.
Graphical Abstract 相似文献Some studies have suggested that bariatric surgery improves pulmonary function in patients with obesity, but whether it alleviates pulmonary ventilation disorders in patients with obesity, type 2 diabetes mellitus (T2DM), and restrictive ventilatory dysfunction(RVD) is unclear. To evaluate the effect of laparoscopic sleeve gastrectomy (LSG) in improving pulmonary ventilation function in patients with obesity, T2DM, and RVD.
MethodsWe studied patients with T2DM and RVD (forced vital capacity (FVC) predicted < 80%, forced expiratory volume in one second/forced vital capacity (FEV1/FVC) > 70%) who underwent LSG from March 2018 to January 2020. Baseline data was recorded and follow-up visits were made at 3, 6, 9, and 12 months after surgery to evaluate glucose, hemoglobin A1c (HbA1c), body mass index (BMI), and pulmonary ventilation function. We used multivariate analyses to assess the remission of RVD (reversion of FVC to ≥80% of the predicted value).
ResultsWe enrolled 33 patients (mean age 46.9±5.2 years, 21 males). Two patients were lost to follow-up and another patient died. Thirty patients completed follow-up; 24 had remission of RVD (24/33, 72.7%). Multivariate Cox regression analysis showed that lower HbA1c (HR=0.35 (0.16 ~ 0.76), p=0.008), reduced waist size (0.9 (0.83 ~ 0.98), p=0.017), and shorter duration of diabetes (0.67(0.47~0.97), p=0.033) were associated with alleviation of pulmonary ventilation function.
ConclusionsLSG not only controls the body weight and T2DM; it may also relieve pulmonary ventilation dysfunction in patients with obesity, T2DM, and RVD. The waist size, duration of diabetes, and HbA1c before LSG negatively affect recovery of pulmonary ventilation dysfunction.
Graphical abstract 相似文献Obesity is associated with increased breast cancer risk in women. Bariatric surgery induces substantial weight loss. However, the effects of such weight loss on subsequent breast cancer risk in women with obesity are poorly understood. To examine breast cancer incidence and related outcomes in women with obesity undergoing bariatric surgery.
Materials and MethodsThis was a population-based matched cohort study of breast surgery outcomes utilizing linked clinical databases in Ontario, Canada. Women with obesity who underwent bariatric surgery were 1:1 matched using a propensity score to non-surgical controls for age and breast cancer screening history. The main outcomes were incidence of breast cancer after lag periods of 1, 2, and 5 years. Additional outcomes included tumor hormone receptor status, cancer stage, and treatments undertaken. Time-varying Cox proportional hazard models accounting for screening during follow-up were used to model cancer incidence.
ResultsA total of 12,724 women per group were included, average age 45.09. After a 1-year lag, breast cancer incidence occurred in 1.09% and 0.79% of the control and surgery groups, respectively (adjusted hazard ratio, 0.81 [95%CI 0.69–0.95]; p = 0.01). This association was maintained after lag periods of 2 and 5 years. Women in the surgical cohort diagnosed with breast cancer were more likely to have low-grade tumors and less likely to have high-grade tumors (overall p < 0.01). No association was found for tumor hormone receptor status, although the surgical group was more likely to have her2neu-negative tumors (p = 0.01).
ConclusionBariatric surgery was associated with a lower incidence of breast cancer and lower tumor grade in women with obesity. Further evaluation of outcomes, including mortality, is required.
Graphical abstract 相似文献We aimed to assess the changes in composition of bacterial microbiota at two levels of the digestive tract: oral cavity and large intestine in patients 6 months after bariatric surgery.
MethodsThis was a prospective cohort study including patients undergoing bariatric surgery. Before surgery and 6 months after the procedure, oral swabs were obtained and stool samples were provided. Our endpoint was the analysis of the differences in compositions of oral and fecal microbiota prior and after the surgical treatment of obesity.
ResultsBacteria from phylum Bacteroidetes seemed to increase in abundance in both the oral cavity and the large intestine 6 months after surgery among patients undergoing bariatric surgery. The subgroup analysis we conducted based on the volume of weight-loss revealed that patients achieving at least 50% of excess weight loss present similar results to the entire study group. Patients with less favorable outcomes presented an increase in the population of bacteria from phylum Fusobacteria and a decrease of phylum Firmicutes in oral cavity.
ConclusionIntestinal microbiota among these patients underwent similar changes in composition to the rest of the study group. Bariatric surgery introduces a significant change in composition of oral and intestinal microbiota.
Graphical abstract 相似文献Obesity is prevalent among economically disadvantaged and racially underrepresented populations. It has been suggested that socioeconomic factors, race, and lifestyle habits are important factors associated with weight loss and comorbidity remission after bariatric surgery. This study analyzes outcomes of bariatric surgery at a private hospital (PH) versus an affiliated safety-net hospital (SNH).
MethodsRetrospective review of laparoscopic sleeve gastrectomies (LSG) performed by the same surgeons at a PH and SNH in a large metropolitan setting. Demographics, socioeconomic status, insurance status, weight metrics, and perioperative outcomes were compared. A postoperative telephone survey was conducted to study dietary and lifestyle differences between cohorts.
ResultsOf the 243 LSG performed, 141 (58%) occurred at PH versus 102 (42%) at SNH. Most patients at SNH were Hispanic, lower socioeconomic status, and had government-sponsored insurance. Based off the results from the postoperative telephone survey, there were no significant differences in dietary and lifestyle habits between both cohorts. Postoperative weight loss outcomes were similar across cohorts. The two groups had similar percent excess weight loss (EWL) at all time points up to 36 months and similar rates of failure to achieve 50% EWL at 12 months. However, patients at PH had greater resolution of diabetes and hypertension after surgery.
ConclusionOur study demonstrates outcomes after bariatric surgery are similar at a PH and its affiliated SNH. Despite differences in race and socioeconomic factors between the two cohorts, perioperative outcomes, short-term postoperative weight loss, and weight loss failure rates were equivalent between SNH and PH patients.
Graphical abstract 相似文献The present study aimed to evaluate electromyographic activity, bite strength, and masticatory muscle thickness in women without obesity and with severe obesity elected for bariatric surgery. Also, patients with obesity underwent bariatric surgery and were re-evaluated 3 and 6 months after surgery to analyze the influence of bariatric surgery outcomes on the stomatognathic system, a functional anatomical system comprising teeth, jaw, and associated soft tissues.
Material and MethodsThirty-seven women were enrolled in the study. Twenty-one women with class II and III obesity according to the body mass index (BMI) and eligible for bariatric surgery composed the obesity pre-surgery group (Ob). Sixteen women with a normal weight according to BMI composed the non-obesity group (NOb). Afterward, the patients from the Ob group were followed up for 3 and 6 months after undergoing Roux-en-Y gastric bypass. Anthropometry, body composition, and parameters of the stomatognathic system were evaluated.
ResultsThe stomatognathic system of the Ob group had less muscle activity and bite strength, but the thickness of masseter and temporal muscles was larger than the NOb group. We also observed a significant change in the muscular activity and bit strength of the stomatognathic system post-bariatric surgery.
ConclusionEvaluating the stomatognathic system indicated that women with clinically severe obesity have less masticatory efficiency than non-obese. Also, we found a positive influence of bariatric surgery in masticatory activity after 3 and 6 months. Thus, monitoring the parameters of the stomatognathic system could be important in the indication and outcomes of bariatric surgery.
Graphical abstract 相似文献As a restrictive procedure, laparoscopic sleeve gastrectomy (LSG) relies primarily on the reduction of gastric volume. It has been suggested that an immediate postoperative gastric remnant volume (GRV) may influence long-term results of LSG; however, there are no consensus in this matter. The aim of this study was to assess the reproducibility of different radiographic methods of GRV calculation and evaluate their correlation with the weight loss (WL) after surgery.
MethodsThis retrospective study evaluated 174 patients who underwent LSG in the period from 2014 to 2017. Using UGI, GRV was measured with 3 different mathematical methods by 2 radiologists. Intraobserver and interobserver calculations were made. Correlation between GRV and WL were estimated with calculations percentage of total weight loss (%TWL) and percentage of excess weight loss (%EWL) after 1, 3, 6, 12, 18, and 24 months postoperatively.
ResultsDuring analysis of intraobserver similarities, the results of ICC calculation showed that reproducibility was good to excellent for all GRV calculation methods. The intraobserver reproducibility for Reader I was highest for cylinder and truncated cone formula and for Reader II for ellipsoid formula. The interobserver reproducibility was highest for ellipsoid formula. Regarding correlation between GRV and WL, significant negative correlation has been shown on the 12th month after LSG in %TWL and %EWL for every method of GRV calculation, most important for ellipsoid formula (%TWL – r(X,Y) = -0.335, p < 0.001 and %EWL – r(X,Y) = -0.373, p < 0.001).
ConclusionRadiographic methods of GRV calculation are characterized by good reproducibility and correlate with the postoperative WL.
Graphical Abstract 相似文献This study aimed to evaluate the impact of gestational weight gain (GWG) after laparoscopic sleeve gastrectomy (LSG) on maternal and perinatal outcomes according to the Institute of Medicine (IOM) recommendations.
Materials and MethodsA retrospective, multicenter, observational study of pregnant women who had undergone LSG between 2012 and 2021 was conducted. According to the IOM criteria, GWG was grouped as insufficient, appropriate, and excessive.
ResultsA total of 119 pregnancies were included in this study. GWG was appropriate in 28 (23.5%), insufficient in 32 (26.9%), and excessive in 59 (49.6%) of the cases. The time from operation to conception was significantly longer in the excessive group than in the insufficient (P = 0.000) and appropriate groups (P = 0.01). The mean GWG was significantly higher in the excessive group than in the appropriate (P = 0.000) and insufficient groups (P = 0.000). When the groups were evaluated according to the IOM recommendations, no statistically significant difference were found between the groups regarding birthweight, gestational age (GA), preterm birth, and whether their child was small or large for their gestational age. Furthermore, there were no differences in terms of anemia and ferritin deficiency level at early pregnancy and predelivery between the groups.
ConclusionThe GWG after LSG did not impact maternal and perinatal outcomes.
Graphical abstract 相似文献Incidence of super obesity (SO; BMI ≥ 50 kg/m2) is growing rapidly and confers worse metabolic complications than non-SO (BMI 30–50 kg/m2). We aim to characterize bariatric surgery patients with SO, their postoperative complications, and treatment trends over the last 5 years in hopes of informing SO-specific treatment protocols.
Materials and MethodsThe MBSAQIP database was analyzed, and two cohorts were compared, those with SO and non-SO. Univariate analysis was performed to determine between-group differences. Multivariable logistic regression analysis was performed to determine if SO was independently associated with serious complications or mortality.
ResultsWe evaluated 751,952 patients with 173,110 (23.0%) having SO. Patients with SO were younger (42.2 ± 11.8 SO vs 45.1 ± 12.0 years non-SO, p < 0.001) and less likely to be female (74.8% vs 81.1%, p < 0.001). While comorbidities seem to be decreasing overall in bariatric surgery patients, those with SO have worse functional capacity and more endocrine, pulmonary, and vascular comorbidities. Patients with SO also have worse 30-day postoperative complications, and SO was independently associated with severe complications (OR 1.08; CI 1.05–1.11, p < 0.001) and mortality (OR 2.49; CI 2.12–2.92, p < 0.001)
ConclusionsPatients with SO have significantly increased preoperative comorbidities resulting in worse postoperative outcomes. SO remains an independent risk factor for serious complications and the greatest independent risk factor for 30-day postoperative mortality. Considering the expected increase in patients with SO, substantial work is required to optimize bariatric surgery strategies specific to these patients.
Graphical abstract 相似文献Obesity in childbearing women leads to pregnancy-related complications such as gestational diabetes mellitus, pregnancy-associated hypertensive disorders, and macrosomia. Weight loss helps reduce these complications. Studies show bariatric surgery reduces obesity-related complications during and after pregnancy. However, bariatric surgery might be associated with adverse outcomes, such as low birth weight and small-for-gestational-age infants. In addition, several studies suggest pregnancy occurring less than a year post-bariatric surgery adversely affects pregnancy outcomes and causes micronutrients deficiency since the dramatic weight loss occurs in the first year. These adverse outcomes may lead to nutritional malabsorption, such as anemia and low vitamin B12 and folic acid levels. The review aims to overview obesity-related complications during pregnancy and the benefits and risks of bariatric surgery on pregnancy outcomes and maternal nutrition status.
Graphical abstract 相似文献Bariatric surgery for patients with severe obesity (body mass index (BMI) ≥ 50kg/m2) is technically challenging. Intragastric balloon (IGB) has been proposed for weight loss before bariatric surgery to reduce surgical risks but its efficacy remains unclear. We conducted a systematic review and meta-analysis of the effectiveness of IGB as bridging therapy and assess potential complications. Amongst 2419 citations, 13 studies were included. IGB resulted in a BMI reduction of 6.60 kg/m2 (MD=6.60, 95% CI: 5.06–8.15; I2=72%). The total post-procedural complication rate was 8.13% (95% CI: 4.04–13.17%), with majority being balloon intolerance. Overall, IGB is effective as a bridging therapy with adequate procedural safety profile, but further study is needed to evaluate the risk reduction for bariatric surgery and long-term weight-loss outcomes.
Graphical abstract 相似文献Postoperative nausea and vomiting (PONV) occurs frequently after bariatric surgery and is a major cause of adverse outcomes. This retrospective study investigated whether opioid-restricted total intravenous anesthesia using dexmedetomidine as a substitute for remifentanil can reduce PONV in bariatric surgery.
Materials and MethodsThe electronic medical records of adult patients who underwent laparoscopic bariatric surgery between January and December 2019 were reviewed. The patients were divided into two groups according to the agents used for anesthesia: Group D, propofol and dexmedetomidine; Group R, propofol and remifentanil.
ResultsA total of 134 patients were included in the analyses. The frequency of postoperative nausea was significantly lower in Group D than that in Group R until 2 h after discharge from the postanesthesia care unit (PACU) (P?=?0.005 in the PACU, P?=?0.010 at 2 h after PACU discharge) but failed to significantly reduce the overall high incidence rates of 60.5% and 65.5%, respectively (P?=?0.592). Postoperative pain score was significantly lower in Group D until 6 h after PACU discharge. The rates of rescue antiemetic and analgesic agent administration in the PACU were significantly lower in Group D than those in Group R.
ConclusionOpioid-restricted total intravenous anesthesia using dexmedetomidine reduces postoperative nausea, pain score, antiemetic, and analgesic requirements in the immediate postoperative period after bariatric surgery.
Graphical abstract 相似文献Bariatric surgery (BS) may help transplant patients by improving their comorbidities and graft function and reducing the recurrence of the disease that led to the transplant. Different timings for BS have been proposed. This study aims to describe the outcomes of BS before, during, and after solid organ transplantation.
MethodsWe identified patients with history of solid organ transplantation that underwent BS between January 1, 2012, and April 31, 2022, at our hospital site. We analyzed patients’ demographics, obesity-related comorbidities, and transplant history. Measured outcomes included post-operative morbidity; readmission; comorbidity management; weight loss at 6-, 12-, and 24-month follow-up; and survival.
ResultsSeventy-eight patients were included in our analysis, with a median age of 57 (28–75) years and a median BMI of 40.91 (28.9–61) kg/m2. The most transplanted organ was the liver (53.6%), followed by the kidney (31.9%). Ten patients underwent BS before the transplant, 11 had simultaneous BS and liver transplant, and 57 underwent BS after the transplant. The median operative time, ICU requirement, length of hospital stay, and early post-operative complications were significantly higher in the simultaneous group. The median EBWL% at 6-, 12-, and 24-month follow-up was 47.51%, 57.89%, and 64.22%, respectively, with no significant difference between the three groups. Thirty-four (44.3%) and 40 (50.8%) patients reduced their HTN and DM medication dosage, respectively. One- and five-year survival rates were 98.2% and 87.4%.
ConclusionBS before, during, or after solid organ transplant is safe, leads to a significant weight loss and improvement of obesity-related comorbidities, and improves patient’s survival.
Graphical Abstract 相似文献Visible light spectroscopy (VLS) represents a sensitive, non-invasive method to quantify tissue oxygen levels and detect hypoxemia. The aim of this study was to assess the microperfusion patterns of the gastric pouch during laparoscopic Roux-en-Y gastric bypass (LRYGB) using the VLS technique.
MethodsTwenty patients were enrolled. Tissue oxygenation (StO2%) measurements were performed at three different localizations of the gastric wall, prior and after the creation of the gastric pouch, and after the creation of the gastro-jejunostomy.
ResultsPrior to the creation of the gastric pouch, the lowest StO2% levels were observed at the level of the distal esophagus with a median StO2% of 43 (IQR 40.8–49.5). After the creation of the gastric pouch and after the creation of the gastro-jejunostomy, the lowest StO2% levels were recorded at the level of the His angle with median values of 29% (IQR 20–38.5) and 34.5% (IQR 19–39), respectively. The highest mean StO2 reduction was recorded at the level of the His angle after the creation of the gastric pouch, and it was 18.3% (SD ± 18.1%, p < 0.001). A reduction of StO2% was recorded at all localizations after the formation of the gastro-jejunostomy compared to the beginning of the operation, but the mean differences of the StO2% levels were statistically significant only at the resection line of the pouch and at the His angle (p = 0.044 and p < 0.001, respectively).
ConclusionGastric pouch demonstrates reduction of StO2% during LRYGB. VLS is a useful technique to assess microperfusion patterns of the stomach during LRYGB.
Graphical abstract 相似文献Robotic approaches have been steadily replacing laparoscopic approaches in metabolic and bariatric surgeries (MBS); however, their superiority has not been rigorously evaluated. The main goal of the study was to evaluate the 5-year utilization trends of robotic MBS and to compare to laparoscopic outcomes.
MethodsRetrospective analysis of 2015–2019 MBSAQIP data. Kruskal-Wallis test/Wilcoxon and Fisher’s exact/chi-square were used to compare continuous and categorical variables, respectively. Generalized linear models were used to compare surgery outcomes.
ResultsThe use of robotic MBS increased from 6.2% in 2015 to 13.5% in 2019 (N= 775,258). Robotic MBS patients had significantly higher age, BMI, and likelihood of 12 diseases compared to laparoscopic patients. After adjustment, robotic MBS patients showed higher 30-day interventions and 30-day readmissions alongside longer surgery time (26–38 min).
ConclusionRobotic MBS shows higher intervention and readmission even after controlling for cofounding variables.
Graphical Abstract 相似文献Although racial inequalities in referral and access to bariatric surgical care have been well reported, racial difference in the selection of surgical techniques is understudied. This study examined factors associated with the utilization of the two main bariatric surgical techniques: laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).
Materials and MethodsThe National Inpatient Sample database was queried for patients who underwent elective LSG or LRYGB for the treatment of severe obesity. Chi-square tests and multivariable logistic regression assessed associations of surgical approach with patient and facility characteristics. Sensitivity analyses examined the following body mass index (BMI) subgroups:?<?40.0 kg/m2, 40.0–44.9 kg/m2, 45.0–49.9 kg/m2, and?≥?50.0 kg/m2.
ResultsWithin the final cohort (N?=?86,053), 73.0% (N?=?62,779) underwent LSG, and 27.0% (N?=?23,274) underwent LRYGB. Patients with BMI 45.0–49.9 kg/m2 (OR?=?0.85) and BMI?≥?50.0 kg/m2 (OR?=?0.80) were less likely to undergo LSG than patients with BMI 40.0–45.0 kg/m2 (all p?<?0.001). However, Black (OR?=?1.74) and White Hispanic patients (OR?=?1.30) were more likely to undergo LSG than White non-Hispanic patients (all p?<?0.005). In the BMI?≥?50.0 kg/m2 group, Black patients were still more likely to undergo LSG compared to White non-Hispanic patients (OR?=?1.69, p?<?0.001), while Asians/Pacific Islanders were less likely to receive LSG than White non-Hispanic patients (OR?=?0.41, p?<?0.05).
ConclusionIn this observational study, we identified racial differences in the selection of common bariatric surgical approaches across various BMI categories. Future investigations are warranted to study and to promote awareness of the racial/ethnic influence in attitudes on obesity, weight loss, financial support, and surgical risks during bariatric discussions with minorities.
Graphical abstract 相似文献Obesity is associated with metabolic syndrome (MBS), a cluster of components including central obesity, insulin resistance (IR), dyslipidemia, and hypertension. IR is the major risk factor in the development and progression of type 2 diabetes mellitus in obesity and MBS. Predicting preoperatively whether a patient with obesity would have improved or non-improved IR after bariatric surgery would improve treatment decisions.
MethodsA prospective cohort study was conducted between August 2019 and September 2021. We identified pre- and postoperative metabolic biomarkers in patients who underwent laparoscopic sleeve gastrectomy. Patients were divided into two groups: group A (IR < 2.5), with improved IR, and group B (IR ≥ 2.5), with non-improved IR. A prediction model and receiver operating characteristics (ROC) were used to determine the effect of metabolic biomarkers on IR.
ResultsSeventy patients with obesity and MBS were enrolled. At 12-month postoperative a significant improvement in lipid profile, fasting blood glucose, and hormonal biomarkers and a significant reduction in the BMI in all patients (p = 0.008) were visible. HOMA-IR significantly decreased in 57.14% of the patients postoperatively. Significant effects on the change in HOMA-IR ≥ 2.5 were the variables; preoperative BMI, leptin, ghrelin, leptin/ghrelin ratio (LGr), insulin, and triglyceride with an OR of 1.6,1.82, 1.33, 1.69, 1.77, and 1.82, respectively (p = 0.009 towards p = 0.041). Leptin had the best predictive cutoff value on ROC (86% sensitivity and 92% specificity), whereas ghrelin had the lowest (70% sensitivity and 73% specificity).
ConclusionPreoperative BMI, leptin, ghrelin, LGr, and increased triglycerides have a predictive value on higher postoperative, non-improved patients with HOMA-IR (≥ 2.5). Therefore, assessing metabolic biomarkers can help decide on treatment/extra therapy and outcome before surgery.
