[PMID: 38981958 DOI: 10.1007/s11695-024-07330-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 05/28/2024] [Accepted: 05/29/2024] [Indexed: 07/11/2024]
Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric surgery procedure in China. However, its cost-effectiveness in Chinese patients is currently unknown. OBJECTIVES This study aims to assess the cost-effectiveness of LSG vs no surgery in Chinese patients with severe and complex obesity, taking into account both healthcare expenses and the potential improvement in health-related quality of life (HRQoL). METHODS A retrospective cohort study was conducted, encompassing 135 Chinese patients who underwent LSG between January 3, 2022 and December 29, 2022, at a major bariatric center. The study evaluated the cost-effectiveness from a healthcare service perspective, employing the incremental cost-effectiveness ratio (ICER) for quality-adjusted life years (QALYs) gained. The analyses compared LSG with the alternative of not undergoing surgery over a 1-year period, using actual data, and extended to a lifetime horizon by projecting costs and utilities at an annual discount rate of 3.0%. Subgroup analyses were undertaken to explore cost-effectiveness variations across different sex, age and BMI categories, and diabetes status, employing a one-way analysis of variance (ANOVA). To ensure the reliability of the findings, one-way and probabilistic sensitivity analyses were executed. RESULTS The results indicated that 1-year post-LSG, patients achieved an average total weight loss (TWL) of (32.7 ± 7.3)% and an excess weight loss (EWL) of (97.8 ± 23.1)%. The ICER for LSG compared to no surgery over a lifetime was $4,327/QALY, significantly below the willingness-to-pay (WTP) threshold for Chinese patients with severe and complex obesity. From a lifetime perspective, LSG proved to be cost-effective for all sex and age groups, across all BMI categories, and for both patients with and without diabetes. Notably, it was more cost-effective for younger patients, patients with higher BMI, and patients with diabetes. CONCLUSIONS LSG is a highly cost-effective intervention for managing obesity in Chinese patients, delivering substantial benefits in terms of HRQoL improvement at a low cost. Its cost-effectiveness is particularly pronounced among younger individuals, those with higher BMI, and patients with diabetes.

Obes Surg 2024; 34:1075-1085. [PMID: 38438667 PMCID: PMC11026210 DOI: 10.1007/s11695-024-07118-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 02/16/2024] [Accepted: 02/16/2024] [Indexed: 03/06/2024]
Abstract
PURPOSE This IFSO survey aims to describe the current trends of metabolic and bariatric surgery (MBS) reporting on the number and types of surgical and endoluminal procedures performed in 2020 and 2021, in the world and within each IFSO chapter. METHODS All national societies belonging to IFSO were asked to complete the survey form. The number and types of procedures performed (surgical and endoluminal interventions) from 2020 to 2021 were documented. A special section focused on the impact of COVID-19, the existence of national protocols for MBS, the use of telemedicine, and any mortality related to MBS. A trend analysis of the data, both worldwide and within each IFSO chapter, was also performed for the period between 2018 and 2021. RESULTS Fifty-seven of the 74 (77%) IFSO national societies submitted the survey. Twenty-four of the 57 (42.1%) reported data from their national registries. The total number of surgical and endoluminal procedures performed in 2020 was 507,806 and in 2021 was 598,834. Sleeve gastrectomy (SG) remained the most performed bariatric procedure. Thirty national societies (52%) had regional protocols for MBS during COVID-19, 61.4% supported the use of telemedicine, and only 47.3% collected data on mortality after MBS in 2020. These percentages did not significantly change in 2021 (p > 0.05). CONCLUSIONS The number of MBS markedly decreased worldwide during 2020. Although there was a positive trend in 2021, it did not reach the values obtained before the COVID-19 pandemic. SG continued to be the most performed operation. Adjustable gastric banding (AGB) continues to decrease worldwide.

Abstract
PURPOSE Obesity is known to be associated with colorectal adenoma (CRA) and colorectal cancer (CRC); yet colonoscopy is not considered an essential preoperative evaluation before bariatric/metabolic surgery. The aim of this study was to clarify the clinical significance of preoperative colonoscopy for obese Japanese patients. METHODS The subjects of this retrospective study were 114 patients who underwent screening colonoscopy before bariatric/metabolic surgery. Multivariate analyses were performed to evaluate the independent predictors of CRA/CRC among the characteristics identified as significant or nearly significant by univariate analyses. RESULTS Colonoscopy revealed abnormal findings indicating the need for biopsy or polypectomy in 20 of the 114 patients (17.5%), and CRA was diagnosed in 13 patients (11.4%). Three patients (2.6%), who were all ≥ 56 years old, had a CRA ≥ 10 mm in diameter. The multivariate analysis showed that older age and male sex were significant predictors of CRA/CRC, which was identified in 46.2% of the male patients aged ≥ 46 years. CONCLUSION Our findings suggest that older age and male sex may be risk factors for CRA/CRC in obese Japanese candidates for bariatric/metabolic surgery; thus, preoperative colonoscopy should be considered for these high-risk patients.

JOURNAL OF METABOLIC AND BARIATRIC SURGERY 2023; 12:67-75. [PMID: 38196787 PMCID: PMC10771973 DOI: 10.17476/jmbs.2023.12.2.67] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 11/14/2023] [Accepted: 11/14/2023] [Indexed: 01/11/2024]
Abstract
Purpose To identify weight loss prediction models by validating previous models using weight loss success criteria. Materials and Methods Patients with morbid obesity from 4 hospitals were retrospectively analyzed between Jan 2019 and 2022. Preoperative demographics, postoperative data, and 1-year follow-up weight loss outcomes were compared between 2 groups who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). Additionally, the predictive factors for the success of excess weight loss (EWL) (>50%) and total weight loss (TWL) (>25%) were analyzed. Results Of the 162 patients, 137 were enrolled during the study period, 75 underwent LSG, and 62 underwent LRYGB. The >50% EWL and >25% TWL 1 year after surgery were 61.3% and 43.1%, respectively. Diabetes mellitus medication use was reduced in 94.8% of patients with type 2 diabetes mellitus. Male sex and body mass index (BMI) were independent risk factors for successful weight loss (SWL) or >50% EWL (odds ratio [OR] for BMI 0.830, 95% confidence interval [CI] 0.764-0.902), whereas achieving >25% TWL was not affected by sex or BMI (OR for BMI 1.010, 95% CI 0.957-1.065). External validation of the prediction models showed an acceptable range of accuracy (adjusted R2 66.5-71.3%). Conclusion LSG and LRYGB are feasible and effective bariatric procedures for SWL in Korean patients with morbid obesity. The TWL model was a more appropriate criterion than EWL, and weight loss prediction models may help assess the 1-year outcomes of bariatric surgery.

Abstract
Metabolic and bariatric surgery (MBS) is an effective treatment for patients with morbid obesity and its comorbidities. However, many patients experience weight regain (WR) after achieving their nadir weight. Establishing the definition of WR is challenging as postoperative WR has various definitions. Risk factors for WR after MBS include anatomical, racial, hormonal, metabolic, behavioral, and psychological factors, and evaluating such factors preoperatively is necessary. Long-term regular follow-up and timely treatment by a multidisciplinary team are important because WR after surgery is multi-factorial. Although lifestyle interventions that focus on appropriate dietary education, physical activity education or interventions, and behavioral psychological interventions are suggested, more well-designed studies are needed because studies evaluating intervention methods and the effectiveness of WR prevention are lacking. Anti-obesity drugs can be used to prevent and manage patients with WR after MBS; however, more research is needed to determine the timing, duration, and type of anti-obesity drugs used to prevent WR.

Abstract
BACKGROUND Bariatric surgery (BS) is a relatively novel surgical field and is in continuous expansion and evolution. PURPOSE Aim of this study was to report changes in Italian surgical practice in the last decade. METHODS The Società Italiana di Chirurgia dell'Obesità (SICOB) conducted annual surveys to cense activity of SICOB centers between 2011 and 2021. Primary outcome was to detect differences in frequency of performance of adjustable gastric banding (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), one anastomosis gastric bypass (OAGB), bilio-pancreatic diversion (BPD), and gastric plication (GP). Secondary outcome was to detect differences in performance of main non-malabsorptive procedures (AGB + SG) and overall bypass procedures (RYGB + OAGB). Geographical differences were also investigated. RESULTS Median response rate was 92%. AGB declined from 36% of procedures in 2011 to 5% in 2021 (p < 0.0001). SG increased from 30% in 2011 to 55% in 2021 (p < 0.0001). RYGB declined from 25 to 12% of procedures (p < 0.0001). OAGB rose from 0% of procedures in 2011 to 15% in 2021 (p < 0.0001). BPD underwent decrease from 6.2 to 0.2% in 2011 and 2021, respectively (p < 0.0001). Main non-malabsorptive procedures significantly decreased while overall bypass procedures remained stable. There were significant differences among regions in performance of SG, RYGB, and OAGB. CONCLUSIONS BS in Italy evolved significantly during the past 10 years. AGB underwent a decline, as did BPD and GP which are disappearing and RYGB which is giving way to OAGB. The latter is rising and is the second most-performed procedure after SG which has been confirmed as the preferred procedure by Italian bariatric surgeons.
