Banded versus non-banded Roux-en-Y gastric bypass: short, mid, and long-term surgical outcomes - a systematic review and meta-analysis. Surg Obes Relat Dis 2024; 20:880-889. [PMID: 38960827 DOI: 10.1016/j.soard.2024.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 04/29/2024] [Accepted: 05/17/2024] [Indexed: 07/05/2024]
Abstract
BACKGROUND The Roux-en-Y gastric bypass (RYGB) is considered as one of the most effective treatments for people with obesity. A variant of this procedure, the banded-RYGB, may present several advantages over the standard technique. These potential benefits include enhanced weight loss, decreased recurrent weight gain, a lower incidence of dumping syndrome, and less distention of the jejunum below the gastrojejunostomy. OBJECTIVES The objective of this meta-analysis is to compare the surgical outcomes of RYGB procedures with a band (banded-RYGB) and without a band (RYGB) in the management of individuals with obesity. SETTING A systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane protocol (PROSPERO ID: CRD42023439874). METHOD The systematic review process led to the identification of 13 comparative studies involving 3230 patients who underwent banded-RYGB and 5302 who received RYGB, all of which were eligible for inclusion and meta-analysis. RESULTS Four studies reported data on 1-year postoperative percent excess weight loss (%EWL), demonstrating a significant increase of 6.03 %EWL in patients who underwent banded-RYGB. Four studies reported the 2-year postoperative %EWL, showing that patients who had banded-RYGB experienced a 5.32 greater %EWL compared to those who received RYGB, even if this was not statistically significant. For 5-year %EWL after bariatric surgery, 5 studies were included for continuous outcome meta-analysis. The average 5-years %EWL difference was 7.6 in favor of banded-RYGB. Patients who had banded-RYGB presented a nonsignificant 1.45 OR of developing postoperative complications compared to patients receiving RYGB. CONCLUSION This meta-analysis demonstrates that, compared to RYGB, patients who underwent banded-RYGB surgery showed a statistically significant increase in the %EWL at 1, 2, and 5 years postoperatively. Moreover, the banding procedure does not significantly increase the risk of postoperative complications.

[PMID: 38172751 PMCID: PMC10765846 DOI: 10.1186/s12893-023-02295-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 12/14/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Patients with class I obesity may need metabolic and bariatric surgery (MBS) in the presence of obesity-associated medical problems, but MBS in this class of obesity is under debate. This study aimed to investigate the efficacy and safety of MBS in patients with class I obesity. METHODS AND MATERIALS This study was a historical cohort carried out on 112 patients with class I obesity with body mass index (BMI) of 30-35 kg/m2 with a 24-month follow-up underwent MBS at Rasoul-e-Akram Hospital. The required data were extracted through the Iran National Obesity Surgery Database. The data required for the study consisted of demographic information such as age, gender, and obesity-associated medical problems like type-2 diabetes mellitus (T2DM), hypertension, obstructive sleep apnea, and dyslipidemia before surgery, 6, 12, and 24 months after surgery. RESULTS Mean age of the patients was 38.10 ± 10.04 years; mean BMI was 32.96 ± 1.35 kg/m2 and 83.9% (n = 94) of patients were female. Out of 18 patients with T2DM, 11 patients (61.11%) had complete remission and seven patients (38.88%) had partial remission. Obstructive sleep apnea, hypertension, dyslipidemia, and gastroesophageal reflux disease were observed in 18 (16.07%), 23 (20.53%), 43 (38.39%), and 13 patients (11.60%) before surgery and resolved at 24-month follow-up. Post-operative complications during the 24-month follow-up were checked to assess safety and there were no De novo gastroesophageal reflux disease, intolerance, leakage, pulmonary thromboembolism, deep vein thrombosis, incisional hernia, hypoalbuminemia (Albumin < 3.5 g/dl), excessive weight loss (BMI < 18.5 kg/m2) at any time during 24-months follow-ups and mortality. Early complications occurred as splenic injury in one case (0.89%), wound infection in one patient (0.89%), and extra-luminal bleeding in 10 (8.92%) after surgery, without any mortality. CONCLUSION MBS is safe and effective in class I obesity and can be considered in selected patients with obesity-associated medical problems.

A low serum iron level is a potential predictor of poor renal function in patients following laparoscopic sleeve gastrectomy: a retrospective study. Sci Rep 2021; 11:22280. [PMID: 34782668 PMCID: PMC8593062 DOI: 10.1038/s41598-021-01608-5] [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: 06/19/2021] [Accepted: 11/01/2021] [Indexed: 11/08/2022] Open
Abstract
This study aimed to assess the association of serum iron level (Iron) with the estimated glomerular filtration rate (eGFR) after bariatric surgery (BS). We reviewed 210 patients with mean age of 39.1 ± 10.6 years (body mass index, 41.4 ± 5.5 kg/m2) undergoing BS. The primary outcome was the relationship between Iron and eGFR at 12-month after surgery. Multiple linear regression analyses were performed using postoperative eGFR as dependent variables and using Iron and other variables (i.e., age) as independent variables. At 12-month follow-up, 94 patients were analyzed. BMI significantly decreased, whereas serum iron level significantly increased. Although the percentage of patients with eGFR of < 90 mL/min/1.73 m2 increased during the study period, no significant difference was found in postoperative 12-month eGFR. No correlations were noted between Iron and eGFR at baseline and postoperative 1 and 6 months, whereas a significant relationship was observed between Iron and postoperative 12-month eGFR. Multiple linear regression analyses revealed that Iron and presence of diabetes were the independent predictors of postoperative 12-month eGFR. This pilot study showed a positive association of postoperative serum iron level with renal function in this patient population. Further large-scale trials are needed to confirm the findings.

Abstract
BACKGROUND Standardization of the key measurements of a procedure's finished anatomic configuration strengthens surgical practice, research, and patient outcomes. A consensus meeting was organized to define standard versions of 25 bariatric metabolic procedures. METHODS A panel of experts in bariatric metabolic surgery from multiple continents was invited to present technique descriptions and outcomes for 4 classic, or conventional, and 21 variant and emerging procedures. Expert panel and audience discussion was followed by electronic voting on proposed standard dimensions and volumes for each procedure's key anatomic alterations. Consensus was defined as ≥ 70% agreement. RESULTS The Bariatric Metabolic Surgery Standardization World Consensus Meeting (BMSS-WOCOM) was convened March 22-24, 2018, in New Delhi, India. Discussion confirmed heterogeneity in procedure measurements in the literature. A set of anatomic measurements to serve as the standard version of each procedure was proposed. After two voting rounds, 22/25 (88.0%) configurations posed for consideration as procedure standards achieved voting consensus by the expert panel, 1 did not attain consensus, and 2 were not voted on. All configurations were voted on by ≥ 50% of 50 expert panelists. The Consensus Statement was developed from scientific evidence collated from presenters' slides and a separate literature review, meeting video, and transcripts. Review and input was provided by consensus panel members. CONCLUSIONS Standard versions of the finished anatomic configurations of 22 surgical procedures were established by expert consensus. The BMSS process was undertaken as a first step in developing evidence-based standard bariatric metabolic surgical procedures with the aim of improving consistency in surgery, data collection, comparison of procedures, and outcome reporting.

Abstract
Gout is characterized by high serum uric acid (SUA) levels and arthritis. It is associated with obesity and metabolic syndrome. Bariatric surgery has been associated with decreased SUA levels and overall gout incidence. This meta-analysis aims to summarize the current evidence on bariatric surgery, gout and SUA levels. A literature review was performed on papers published from 2000 up till December 2018. Original studies investigating the impact of bariatric surgery on SUA levels or gout incidence were evaluated. Twenty studies with a total of 5,233 patients were analysed. Majority (n=14) had a follow-up duration of at least 12 months. The mean preoperative body mass index (BMI) was 45.2kg m-2 . The mean preoperative SUA level was 6.5mg dL-1 . Subgroup analysis demonstrated a mean decrease in SUA levels (-0.73mg dL-1 ) from the third postoperative month onwards, which was sustained until the third postoperative year (-1.91mg dL-1 ). There was a rise in SUA levels in the first post-operative month. Meta-regression analyses demonstrated a proportionate linear relationship between the change in BMI and SUA levels. Post-bariatric surgery weight loss is associated with reduced SUA levels and decreased incidence of gout attacks. However, this is only evident from the third post-operative month onwards.

Abstract
INTRODUCTION Bariatric surgeries are the only effective long-term treatment in obese patients. The innovation of laparoscopic gastric plication (LGP) raised some questions about its effectiveness compared to traditionally used techniques such as laparoscopic sleeve gastrectomy (LSG). We tried to answer some of these questions. MATERIALS AND METHODS We investigated 70 patients in a randomized clinical trial (IRCT2013123012294N5) from 2012 to 2015. Thirty-five patients were randomly assigned to each LSG or LGP group, using sealed envelope method. The body mass index (BMI) reduction and the percentage of excess weight loss (%EWL) along with %total body weight loss (%TWL) were primary endpoint and were assessed at follow-up periods. We recorded postoperative complications, as well. RESULTS Two-year follow-up rate was 100%. There were no statistically significant differences between the two groups in means of preoperative BMI. Also, postoperative follow-ups were not suggestive for a significant difference in BMI (all p values > 0.05). The mean %EWL at follow-ups showed no significant difference at any point, except for 3 and 6 months after surgery (p value = 0.002 and 0.017, respectively). This finding was confirmed by %TWL trend in 12 months after surgery. LSG patients were readmitted more than LGP patients (seven cases vs one case, p value = 0.024). Postoperative complications such as nausea and vomiting, hair loss, iron deficiency, vitamin D deficiency, and cholelithiasis were not different between the two groups. There was one death in the LGP group due to pulmonary thromboembolism. CONCLUSIONS LGP showed to be efficient regarding %EWL and %TWL reduction in short-term follow-ups with comparable postoperative complications to LSG.

Abstract
OBJECTIVES Obesity is a pandemic health problem. Bariatric surgery is the only efficient method for long-term effective weight loss in subjects with severe obesity. Laparoscopic adjustable gastric banding (LAGB) has been widely applied for weight loss. However, a novel technique called laparoscopic adjustable gastric banded plication (LAGBP) has been proposed as an alternative to LAGB. Surgeons generally consider LAGBP to have a relative advantage on weight loss than that derived from LAGB. This initial study applied various biostatistical models and considered a relative longer observation period to compare the effects of LAGB and LAGBP. METHODS A total of 340 obese patients (290 who underwent LAGB and 50 who underwent LAGBP) with a body mass index of ≥35 kg/m2 and ages 20 to 55 y were recruited from the Division of General Surgery, Taipei Medical University Hospital in Taipei, Taiwan and observed for 24 to 36 mo postoperatively. RESULTS Both surgical procedures resulted in significant weight loss, amelioration of poor glucose metabolism, and decreased serum triacylglycerol levels. However, the trend analysis showed no significant differences between the postoperative effects of LAGB and LAGBP (P for trend = 0.21 for body mass index reduction, 0.13 for total body fat percentage reduction, 0.25-0.29 for glucose metabolism amelioration, and 0.10-0.29 for blood pressure improvement). Improvements in serum total cholesterol and high-density lipoprotein cholesterol levels were observed after LAGB only and LAGBP only, respectively, at 24 mo postoperatively. The Framingham Coronary Heart Disease Risk score also showed significant decrease for patients who underwent LAGB and LAGBP. CONCLUSIONS Both LAGB and LAGBP demonstrated comparable efficacy in reducing body weight and improving metabolic parameters in a 24 to 36 mo follow-up period. LABG showed the ability to reduce systolic blood pressure and LAGBP exhibited triacylglycerol-lowering effects. A longer observational period is needed in future studies.

Abstract
INTRODUCTION AND AIM Laparoscopic sleeve gastrectomy (LSG) is considered one of the most popular bariatric surgeries of the present time. This review aimed to evaluate the progress and short-term outcomes of LSG over the last 5 years. METHODS The systematic review of electronic databases revealed 27 relevant articles, which were carefully assessed. The data extracted from the studies were analyzed and compared with data reported by a previous review published in 2010. RESULTS A total of 5218 patients were included in this review with a mean age of 41.1. The average preoperative body mass index (43.8±8) significantly dropped at 12 months to 30.7±3.9. The average percentage of excess weight loss at 1 year was 67.3. The mean rates of remission of diabetes mellitus, hypertension, and dyslipidemia were 81.9%, 66.5%, and 64.1%, respectively. The mean complication rate across the studies was 8.7% and the average mortality rate was 0.3%. A significant drop in postoperative body mass index, higher percentage of excess weight loss, and significantly lower overall complication rate were observed in comparison with the previous systematic review. CONCLUSIONS LSG continues to achieve satisfactory weight loss and improvement of obesity-related comorbidities with acceptably low morbidity and mortality rates.
