Rates and Risk Factors for 30-Day Morbidity After One-Stage Vertical Banded Gastroplasty Conversions: A Retrospective Analysis.

Background: The vertical banded gastroplasty (VBG) is a historic restrictive bariatric operation often requiring further surgery. In this investigation utilizing the 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) national dataset, we aim to better define the outcomes of VBG conversions.Methods: We queried the 2021 MBSAQIP dataset for patients who underwent a conversion from a VBG to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Demographics, comorbidities, laboratory values, and additional patient factors were examined. Rates of key consequential outcome measures 30-day readmission, reoperation, reintervention, mortality, and a composite endpoint (at least 1 of the 4) were further calculated.Results: We identified 231 patients who underwent conversion from VBG to SG (n = 23), RYGB (n = 208), or other anatomy (n = 6), of which 93% of patients were female, and 22% of non-white race. The median age was 56years and body-mass index (BMI) was 43kg/m2. The most common surgical indications included weight considerations (48%), reflux (25%), anatomic causes (eg, stricture, fistula, and ulcer; 10%), and dysphagia (6.5%). Thirty-day morbidity rates included reoperation (7.8%), readmission (9.1%), reintervention (4.3%), mortality (.4%), and the composite endpoint (15%). Upon bivariate analysis, we did not identify any specific risk factor for the 30-day composite endpoint.Discussion: One-stage VBG conversions to traditional bariatric anatomy are beset with higher 30-day morbidity relative to primary procedures. Additional MBSAQIP data will be required for aggregation, to better characterize the risk factors inherent in these operations.

Incidence and risk factors of post-metabolic and bariatric surgery hypoglycemia: a systematic review.

This study aimed to systematically review the existing literature to summarize the incidence and risk factors of post-metabolic and bariatric surgery hypoglycemia (MBSH). We searched PubMed, Medline, Embase, and the Cochrane Library databases for the studies published from inception to August 2023. Randomized controlled trials and analytical studies that investigated the incidence or risk factors of MBSH after different surgery techniques (including Roux-en-Y gastric bypass, sleeve gastrectomy, gastric banding, duodenal switch, omega-loop gastric bypass, and vertical banded gastroplasty) were involved. The incidence and risk factors of MBSH were extracted and described separately based on different diagnostic criteria and then summarized the risk factors and their statistical findings collectively. Twenty-nine studies were reviewed with follow-up ranging from 1 to 22 years. The incidence of MBSH ranged significantly across different diagnostic methods: 2.6-66.4% (self-report), 6.6-61.8% (oral glucose tolerance test), 29.4-78.6% (mixed-meal tolerance test), and 50-75% (continuous glucose monitoring). Patients with a mean age of 49.8 years and 89.0% of them were women with a better glycemic control who undergo RYGB and achieve 86.5% of estimated weight loss from surgery should be particularly vigilant about the possibility of developing MBSH. Distinct biomarkers such as IGF-1 (OR 1.06), fasting glicentin (AUC 0.81), HbA1c (AUC 0.76), and absolute weight reduction (AUC 0.72), greater fluctuations in glucose (OR 1.98) are valuable in promptly detecting MBSH. Specifically, patients with prior cholecystectomy or antidepressant therapy should be particularly cautious. The review highlights higher MBSH risk in younger women with significant weight loss after RYGB, and those with prior cholecystectomy or antidepressant use. Systematic summarization of MBSH criteria allowed us to identify the predictors for MBSH, which can aid in early diagnosis and treatment, reducing the need for prolonged monitoring.

Comparative effectiveness of metabolic and bariatric surgeries: a network meta-analysis.

Bariatric surgery is recommended for patients with unhealthy weight. Our study aim to compare and rank different bariatric surgical approaches in reducing weight parameters. We searched MEDLINE, Cochrane CENTRAL, Scopus, and Web of Science databases from inception to September 2023. We extracted all outcomes as mean change from the baseline. The mean difference and 95% confidence interval were used as a summary measure. All analysis was conducted with R version 4.2.2 (2022-10-31) and R Studio version 2022.07.2 (2009-2022) (RStudio, Inc.). Included surgeries were: Biliopancreatic diversion (BPD-RYGB), Roux-en-Y Gastric Bypass (RYGB), Laparoscopic Gastric Plication (LGP), Duodenal-Jejunal Bypass Sleeve (DJBS), Single-anastomosis gastric bypass (SAGB), Laparoscopic vertical banded gastroplasty (LVBG), Sleeve Gastrectomy (SG), Laparoscopic adjustable gastric banding (LAGB), Gastric plication, Biliopancreatic diversion (BPD), and Intra-gastric balloon (IGB). Only clinical trials were included, with outcomes focused on weight parameters such as reductions in BMI (kg/m²), weight (kg), waist circumference (cm), fat mass (kg), and excess weight loss (EWL) (%). Our analysis of 67 studies showed that SADI-S was the best surgical technique in decreasing BMI (kg/m2) (MD = -18.06; 95% CI [-25.31; -10.81]) and DS follows in efficacy with a P-score (MD = -18.88; 95% CI [-31.15; -6.62]) however the pooled analysis was heterogeneous (I2 = 98.5%). For weight (kg), waist circumference (cm), and fat mass (kg), BPD-RYGB was the best surgical technique to reduce these parameters (MD = -41.48; 95% CI [-47.80, -35.51], MD = -29.08; 95% CI [-37.16, -21.00], and MD = -31.11; 95% CI [-38.77, -23.46]; respectively). The pooled analysis was heterogeneous except in fat mass (I2 = 0%, p-value = 0.8). Our network meta-analysis showed that the best surgical technique in increasing EWL (%) was RY-DS (MD = -61.27; % CI [-91.72; -30.82]) the next one in efficacy according to P-score was LVBG (MD = -59.03; % CI [-84.47; -33.59]). SADI-S is most effective in reducing BMI followed by RYGB. DS was associated with most estimated weight loss %.

Post Bariatric Surgery Nursing Care

Morbid obesity is defined as having a body mass index (BMI) above 40 or having a BMI of 35 and comorbidities along with obesity. Bariatric surgeries can be grouped into three. These are restrictive surgeries, malabsorption (impairing absorption) surgeries, and both restrictive and malabsorption surgeries. In bariatric surgery, restrictive surgeries such as vertical band gastroplasty (VGB), adjustable gastric banding (AGB) surgeries, malabsorption surgeries such as biliopancreatic diversion (BPD)/duodenal switch (DS) surgeries, and both restrictive and malabsorption surgeries such as Roux-en-Y gastric bypass (RYGB) surgeries, are commonly performed. Post-bariatric surgery care should include a multidisciplinary team consisting of a surgeon, an endocrinologist, a psychiatrist, a dietitian, and a nurse specializing in bariatric surgery. Nursing care after obesity surgery is evaluated as early postoperative care (1-3 days) and late postoperative care. Close observation, careful and complete evaluation are important in the specialist nursing care of bariatric surgery patients. In bariatric surgery, patients are provided with routine post-operative nursing care such as oxygen and hemodynamic monitoring, pain management, mobilization, wound care, deep vein thrombosis prophylaxis, early and frequent ambulation, drain care, fluid balance nutrition, training, and emotional support.

Preoperative Micronutrient Repletion Strategies in Metabolic and Bariatric Surgery: A Systematic Review

BackgroundEvidence is lacking to inform how micronutrient deficiencies should be prevented and treated before metabolic-bariatric surgery to optimize patient outcomes. ObjectiveThis systematic review aimed to examine the effect of preoperative repletion strategies for micronutrient deficiencies on micronutrient biochemistry, quality of life, and complication rates among candidates for metabolic and bariatric surgery compared with usual care, alternate strategies, or no treatment. MethodsPubMed, Embase, CINAHL, and CENTRAL was searched in April 2024. A grey literature search was updated in April 2024 via Google search. Eligible observational and interventional studies were those that provided micronutrient repletion before the surgery and measured micronutrient status pre- and/or postsurgery. Studies with participants who were pregnant, lactating, or elected jejunocolic bypass, jejunoileal bypass, vertical banded gastroplasty, and biliopancreatic diversion were excluded. Risk of bias was assessed using the Academy of Nutrition and Dietetics Quality Criteria Checklist. Findings were narratively synthesized and the Grading of Recommendation, Assessment, Development and Evaluations was adopted when applicable. Twenty studies (n = 27 groups) were included (n = 15 observational; n = 5 interventional). ResultsStrategies targeted vitamins A, D, E, B6, B12, C, thiamin, folate, calcium, iron, selenium, and zinc, including chronic dosing of oral supplements and multivitamins (n = 21), megadoses of oral supplements (n = 1), intramuscular injection (n = 1), intravenous infusion (n = 1), and a mix of injection and oral supplements (n = 3). Preoperative repletion strategies varied in efficacy. Chronic dosing of oral supplements increased vitamin D levels (n = 4 interventional studies; Grading of Recommendation, Assessment, Development and Evaluations rating: moderate). Multivitamins did not improve vitamin B12 status but improved status of vitamin B6, vitamin C, and folate. Iron infusion (n = 1) increased ferritin levels, despite small sample size and low adherence rate, whereas oral iron supplementation resulted in unchanged (n = 4) or decreased (n = 1) ferritin levels. ConclusionsProactive and personalized micronutrient repletion schedules may decrease the risk of preoperative and early postoperative deficiency.

Decision-making Considerations in Revisional Bariatric Surgery.

With drastic variations in bariatric practices, consensus is lacking on an optimal approach for revisional bariatric surgeries. The authors reviewed and consolidated bariatric surgery literature to provide specific revision suggestions based on each index surgery, including adjustable gastric band (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), biliopancreatic diversion with duodenal switch (BPD-DS), single anastomosis duodenal-ileal bypass with sleeve (SADI-S), one anastomosis gastric bypass (OAGB), and vertical banded gastroplasty (VBG). AGB has the highest weight recurrence rate and can be converted to RYGB, SG, and BPD-DS. After index SG, common surgical options include a resleeve or RYGB. The RYGB roux limb can be distalized and pouch resized in context of reflux, and the entire anatomy can be revised into BPD-DS. Data analyzing revisional surgery after a single anastomosis duodenal-ileal bypass with sleeve was limited. In patients with one anastomosis gastric bypass and vertical banded gastroplasty anatomy, most revisions were the conversion to RYGB. As revisional bariatric surgery becomes more common, the best approach depends on the patient's indication for surgery and preexisting anatomy.

Fifteen-year changes in health-related quality of life after bariatric surgery and non-surgical obesity treatment

BackgroundEvidence on the long-term (≥10 years) development of health-related quality of life (HRQoL) following bariatric surgery is still limited and mainly based on small-scale studies. This study aimed to investigate (1) 15-year changes in mental, physical, social, and obesity-related HRQoL after bariatric surgery and non-surgical obesity treatment; and (2) whether sociodemographic factors and pre-operative health status are associated with 15-year HRQoL changes in the surgery group.MethodsParticipants were from the non-randomized, prospective, controlled Swedish Obese Subjects study. The surgery group (N = 2007, per-protocol) underwent gastric bypass, banding or vertical banded gastroplasty, and matched controls (N = 2040) received usual obesity care. Recruitment took place in 1987–2001 and measurements (including six HRQoL scales) were administered before treatment and after 0.5, 1, 2, 3, 4, 6, 8, 10 and 15 years. Multilevel mixed-effect regression models using all observations for estimation were conducted.ResultsSurgical patients experienced greater 15-year improvements in perceived health and overall mood, and greater reductions in depression, obesity-related problems, and social interaction limitations than controls (all p < 0.001, adjusted for baseline differences). Effect size (ES) was classified as large only for obesity-related problems (ES = 0.82). At the 15-year follow-up, surgical patients reported better perceived health (p < 0.001) and less obesity-related problems (p = 0.020) than controls. In the surgery group, patients with baseline diabetes had smaller 15-year reductions in social interaction limitations (p < 0.001) and depression (p = 0.049) compared to those without baseline diabetes. Although surgical patients with a history of psychiatric disorder reported lower HRQoL than those without such history over the 15-year follow-up, there were no significant differences in the long-term improvements between the two groups (p = 0.211–0.902).ConclusionsOver 15 years, surgical patients experienced more positive development of HRQoL compared to those receiving usual care. This difference was large for obesity-related problems, but otherwise the differences were small. Patients with pre-operative diabetes might be at increased risk for smaller long-term HRQoL improvements.

Laparoscopic Versus Robotic Revisional Bariatric Surgery

Abstract Background Revisional bariatric surgery (RBS) represents up to 15% of all bariatric procedures. The most performed conversion procedures are Roux-en-Y-Gastric Bypass (RYGB) and Vertical Sleeve Gastrectomy (VSG) after adjustable gastric banding (AGB), VSG or vertical banded gastroplasty (VBG). While the overall complication rate is known to be higher compared to primary surgery, the optimal surgical approach, laparoscopic or robotic, remains controversial. Aims We aimed to compare laparoscopic and robotic RBS in terms of peri and post-operative complications, ICU admission, operative time, and the length of hospital stay. Methods We conducted a retrospective multi-center case control study of patients who underwent RBS from 2013 to 2023 in two centers. Cases and controls were matched by the index procedure, - AGB or a stapled procedure and the revisional procedure, - RYGB or VSG. Results 59 revisional procedures were performed (36 and 23 per center). After matching according to index and revisional procedures, 46 patients were included, 23 in the robotic and 23 in the laparoscopic group. There were no statistically significant differences in demographics, BMI, or comorbidities between the groups. The overall peri- and early post-operative complication rate was similar while patients in the laparoscopic group had a higher rate of severe complications and reoperations (13% versus 0%), however, without reaching a statistically significant difference (p = 0,07). The operative time was shorter in the laparoscopic group (161 +/- 55 versus 232 +/- 63 minutes, p &amp;lt; 0,05). Conclusion Our retrospective study showed a tendency towards more severe perioperative complications and reoperations in laparoscopic compared to robotic revisional surgery in patients with similar index and conversion procedures. Patients with complex revisional RYGB could benefit from robotic surgery. As the literature provides contrasting results, further studies should be performed to address this question.

Breast Cancer Risk After Bariatric Surgery and Influence of Insulin Levels

Obesity and insulin are risk factors for breast cancer, and retrospective studies suggest bariatric surgery reduces breast cancer risk in women. However, long-term prospective data on breast cancer risk after bariatric surgery and the role of baseline insulin levels are lacking. To examine if bariatric surgery is associated with breast cancer incidence in women and if treatment benefit is modified by baseline insulin levels. The Swedish Obese Subjects (SOS) study was a nonrandomized intervention trial designed to investigate the long-term effects of bariatric surgery on obesity-related mortality and morbidity. Study recruitment took place between 1987 and 2001, and median (IQR) follow-up time was 23.9 years (20.1-27.1) years. The study was conducted at 25 public surgical departments and 480 primary health care centers in Sweden and included 2867 women aged 37 to 60 years and with body mass index 38 or greater (calculated as weight in kilograms divided by height in meters squared). In the surgery group (n = 1420), 260 women underwent gastric banding, 970 vertical banded gastroplasty, and 190 gastric bypass. The remaining contemporaneously matched control individuals (n = 1447) received usual obesity care. Breast cancer, the main outcome of this secondary report, was not a predefined outcome in the SOS study. Breast cancer events were identified in the Swedish National Cancer Registry. The study population comprised 2867 women with a mean (SD) age of 48.0 (6.2) years. During follow-up, there were 154 breast cancer events, 66 in the surgery group and 88 in the usual care group, and a decreased risk of breast cancer was observed in the bariatric surgery group (hazard ratio [HR], 0.68; 95% CI, 0.49-0.94; P = .019; adjusted HR, 0.72; 95% CI, 0.52-1.01; P = .06). The surgical treatment benefit on breast cancer risk was greater in women with baseline insulin levels above the median 15.8 μIU/L (HR, 0.48; 95% CI, 0.31-0.74; P = .001; adjusted HR, 0.55; 95% CI, 0.35-0.86; P = .008) compared to those below (HR, 0.95; 95% CI, 0.59-1.53; P = .84; adjusted HR, 1.01; 95% CI, 0.61-1.66; P = .97; interaction P = .02). This prospective clinical trial indicated a reduced risk of breast cancer after bariatric surgery in women with obesity. The surgical treatment benefit was predominantly seen in women with hyperinsulinemia. ClinicalTrials.gov Identifier: NCT01479452.

Laparoscopic mini-gastric bypass versus laparoscopic Roux-en-Y gastric bypass in redosurgery after failed vertical banded gastroplasty with long gastric pouch

Background Up to 50% of patients who undergo vertical band gastroplasty (VBG) experienced weight regain or complications, like band erosion or slippage, within 5–10 years of the procedure, the aim of the study to evaluate laparoscopic mini-gastric bypass versus laparoscopic Roux-en-Y gastric bypass as a redosurgery after failed VBG. Patients and methods We analyzed the data of 102 patients (38 males and 64 females) underwent revisional surgery after failed VBGs from July 2021 to August 2022, with mean age 45.92 years, follow up for 1 year in Ain Shams University Hospitals. Results The mean hospital stay was 1.8 days (1–4 days), 2.9 days (2–7 days) in Redo laparoscopic mini gastric bypass (R-LMNGB) and Redo laparoscopic roux en Y gastric bypass (R-LRYGB) respectively. Postoperative BMI after 1 year 31.16±27.83 and 31.94±3.69 in R-LMNGB and R-LRYGB, respectively, %EWL show significant difference between two groups after 3 months and 1 year. Postoperative complications rates were 3.92% in R-LRYGB. Conclusions R-LMNGB after failed VBG has almost the same results of R-LRYGB as regard weight loss, improvement of obesity-related comorbidities with less operative time, hospital stay, less anastomosis, and complications.

Outcome comparison between primary and revisional bariatric surgery: A propensity-matched analysis

BackgroundRevisional bariatric procedures for weight recurrence are rising but are considered higher risk and less effective than primary bariatric procedures. This study aimed to compare clinical outcomes between primary and revisional bariatric surgery for weight recurrence. MethodsProspectively collected data from adult patients who underwent revisional or primary bariatric surgery from 2016 to 2020 in an academic institution were reviewed. Roux-en-Y gastric bypass and sleeve gastrectomy were performed primarily or as conversion procedures after laparoscopic adjustable gastric band, vertical banded gastroplasty, and sleeve gastrectomy. 1:1 propensity score matching was performed between revisional bariatric surgery and primary bariatric surgery, and logistic regression analysis was used to compare up to 2-year weight loss and comorbidity resolution outcomes. ResultsA total of172 cases (86 revisional bariatric surgery versus 86 primary bariatric surgery) were included. Groups were matched for age, sex, preoperative body mass index, bariatric procedure, diabetes, hypertension, and obstructive sleep apnea. Procedure duration (203 ± 78 vs 154 ± 69 minutes; P < .001) and length of stay (2.3 ± 2.1 vs 1.7 ± 1 days; P = .02) were longer for revisional bariatric surgery versus primary bariatric surgery, respectively. Total weight loss was less in revisional bariatric surgery compared with primary bariatric surgery at 1 year (23 ± 10% vs 32 ± 9%; P < .001) and 2 years (21 ± 12.% vs 32 ± 10%; P < .001) of follow-up; however, no differences were detected in postoperative occurrences, emergency department visits, readmissions, reintervention and reoperation rates, and comorbidity resolution. ConclusionAlthough revisional bariatric surgery was associated with longer operation times, prolonged hospitalization, and lower weight loss than primary bariatric surgery, it was accomplished safely and led to substantial weight loss and comorbidity resolution. This information can guide patient counseling before revisional surgery for weight recurrence.

Life expectancy after bariatric surgery or usual care in patients with or without baseline type 2 diabetes in Swedish Obese Subjects.

To determine life expectancy and causes of death after bariatric surgery in relation to baseline type 2 diabetes (T2D) in the prospective, Swedish Obese Subjects study. The study included 2010 patients with obesity who underwent bariatric surgery and 2037 matched controls, eligible for surgery. The surgery group underwent gastric bypass (n = 265), banding (n = 376), or vertical banded gastroplasty (n = 1369). The control group (n = 2037) received usual obesity care. Causes of death were obtained from the Swedish Cause of Death Register, case sheets and autopsy reports, in patients with baseline T2D (n = 392 surgery patients/n = 305 controls) or non-T2D (n = 1609 surgery patients/n = 1726 controls) during a median follow-up 26 years. In T2D and non-T2D subgroups, bariatric surgery was associated with increased life expectancy (2.1, 95% confidence interval (95% CI) 0.2-4.0; and 1.6, 0.5-2.7 years, respectively) and reduced overall mortality (adjusted hazard ratio (adjHR) = 0.77, 95% CI: 0.61-0.97; and 0.82, 0.72-0.94, respectively), and the treatment benefit was similar (interaction p = 0.615). Bariatric surgery was associated with reduced cardiovascular mortality in both subgroups (adjHR = 0.65, 95% CI: 0.46-0.91; and 0.70, 0.55-0.88, respectively (interaction p = 0.516)). Bariatric surgery is associated with similar reduction of overall and cardiovascular mortality and increased life expectancy regardless of baseline diabetes status.

Laparoscopic Conversion of Vertical Banded Gastroplasty to Roux-en-Y Gastric Bypass Gives Better Result Compared to an Open Approach.

Vertical banded gastroplasty (VBG) has a relatively high failure rate in the long run, requiring revisional surgery in 30-65%. A common conversion option is to Roux-en-Y gastric bypass (RYGB), which can be performed laparoscopically or open. Current literature contains small cohorts and inconclusive results. Therefore, we set out to compare our series of open and laparoscopic VBG to RYGB conversions. All conversions performed between 1996 and 2020 were included. Patients were divided into 3 groups based on conversion indication: weight recurrence (group 1), excessive weight loss (group 2), and eating/pouch difficulties (group 3). The primary outcome was postoperative complications according to the Clavien-Dindo (CD) classification. Secondary outcome was %total weight loss (%TWL) 1 to 5 years after revisional surgery. We included 205 patients (84.9% female) of whom 105 underwent laparoscopic and 100 open VBG to RYGB conversion. Twenty-three short-term complications occurred in the laparoscopic group, with 16 > CD3a. In the open group, 33 complications occurred with 12 > CD3a. Overall complications were 33.3% in laparoscopic and 64% in open patients. There were no significant differences between the laparoscopic and open group in BMI (p = 0.76) and %TWL (p = 0.694) after 5 years. After 5 years, lost to follow-up was 97% in the open group. Twenty-eight percent of patients who reached follow-up in the laparoscopic group had available data. We demonstrate that the overall complication rate is lower in the laparoscopic group compared to the open group. Regarding BMI, an improvement was achieved in both groups after 5 years.

How Good is Stratification and Prediction Model Analysis Between Primary and Revisional Roux-en-Y Gastric Bypass Surgery? A Multi-center Study and Narrative Review

IntroductionsRevision surgery because of weight recurrence is performed in 2.5–33% of primary vertical banded gastroplasty (VBG), laparoscopic sleeve gastrectomy (LSG), and gastric band (GB) cases. These cases qualify for revisional Roux-en-Y gastric bypass (RRYGB).MethodsThis retrospective cohort study analyzed data from 2008 to 2019. A stratification analysis and multivariate logistic regression for prediction modeling compared the possibility of sufficient % excess weight loss (%EWL) ≥ 50 or insufficient %EWL < 50 between three different RRYGB procedures, with primary Roux-en-Y gastric bypass (PRYGB) as the control during 2 years of follow-up. A narrative review was conducted to test the presence of prediction models in the literature and their internal and external validity.ResultsA total of 558 patients underwent PRYGB, and 338 underwent RRYGB after VBG, LSG, and GB, and completed 2 years of follow-up. Overall, 32.2% of patients after RRYGB had a sufficient %EWL ≥ 50 after 2 years, compared to 71.3% after PRYGB (p ≤ 0.001). The total %EWL after the revision surgeries for VBG, LSG, and GB was 68.5%, 74.2%, and 64.1%, respectively (p ≤ 0.001). After correcting for confounding factors, the baseline odds ratio (OR) or sufficient %EWL ≥ 50 after PRYGB, LSG, VBG, and GB was 2.4, 1.45, 0.29, and 0.32, respectively (p ≤ 0.001). Age was the only significant variable in the prediction model (p = 0.0016). It was impossible to develop a validated model after revision surgery because of the differences between stratification and the prediction model. The narrative review showed only 10.2% presence of validation in the prediction models, and 52.5% had external validation.ConclusionOverall, 32.2% of all patients after revisional surgery had a sufficient %EWL ≥ 50 after 2 years, compared to PRYGB. LSG had the best outcome in the revisional surgery group in the sufficient %EWL group and the best outcome in the insufficient %EWL group. The skewness between the prediction model and stratification resulted in a partially non-functional prediction model.Graphical

Revision of Vertical Banded Gastroplasty to Roux-En-Y Gastric Bypass with 2 Years of Follow-Up

Background: Due to weight regain and GIT symptoms associated with vertical banded gastroplasty (VBG), revisional surgery is necessary. Roux-en-Y gastric bypass (RYGB) is one of the best options as a revision procedure but comes with a high complication rate. Methods: This prospective study included 80 patients undergoing RYGB surgery at Ain Shams University Hospitals after failed VBG surgery, with up to 2 years of follow-up. Results: Eighty patients underwent RYGB correction after VBG. The mean age was 42 ± 6.45 (39–58) years and the mean preoperative body mass index was 45.46 ± 4.135 (38–55) kg/m². The median length of hospital stay for the patients was 4.78 ± 1.84 days. The early postoperative complication rate was 8.7% and the reoperation rate within 30 days was 3.75%, with no mortality. Leakage and bowel injury were detected in 2 patients. After an average follow-up of 2 years, the percentage of EWL was 64.47 ± 19.3, and complete resolution of VBG-related GIT symptoms was achieved in approximately all patients. Late complications occurred in 7.5% of patients, of whom 3.75% required surgery. Conclusion: Conversion to RYGB is feasible with a limited short-term complication and reoperation rate; long-term results show a nearly complete resolution of VBG-related symptoms and a statistically significant positive impact on weight loss.

Short-Term (30-Day) Morbidity of Biliopancreatic Diversion Compared to Roux-en-Y Gastric Bypass as Revisional Procedures for Failed Vertical Banded Gastroplasty.

Silastic ring vertical gastroplasty (SRVG) and vertical banded gastroplasty (VBG) are associated with a high failure rate due to weight regain and complications at long-term follow-up. Consequently, surgical correction for such procedures is warranted. Controversy exists as to which surgical procedure is the ideal choice for such correction. Our aim is to compare short-term outcome of Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) repair for failed VBG/SRVG bariatric procedures. The medical records of patients with failed SRVG who underwent corrective procedures at our institute between 2004 and 2018 were retrospectively reviewed. Patients characteristics, surgical approaches, and intraoperative and post-operative complications were examined and compared. Sixty patients in total underwent a surgical corrective procedure for failed SRVG. Thirty-one patients underwent RYGB, and 29 patients underwent BPD. Major complications were seen more in the RYGB group (35% = 11) compared to the BPD (6.9% = 2). Even though anastomotic leak rates were not statistically significant (p = 0.053), an apparent tendency for such a complication was noted in the RYGB group. RYGB procedure had an increased 30-day complication rate (p = 0.055) compared to RYGB. Laparoscopic approach had statistically fewer complications than open approach. No mortality was observed in either group. Our study showed that BPD is a safe option with less complication rates than RYGB in the short-term period for surgical correction of failed VBG/SRVG procedures.
