Sleeve plus procedures: need of time

Weight-Related Outcomes After Revisional Bariatric Surgery in Patients with Non-response After Sleeve Gastrectomy-a Systematic Review

Weight non-response after sleeve gastrectomy is an emerging issue. This systematic review compared revisional procedures for weight-related outcomes. We searched several databases for relevant articles and included adult patients with revisional bariatric procedures after primary sleeve gastrectomy. Twelve trials with 1046 patients were included, covering five revisional procedures. There were no randomised controlled trials, and 10 studies had a critical risk of bias. Significant variations in inclusion criteria, therapy benchmarks, follow-up schemes, and outcome measurements were observed, preventing meaningful comparison of results. Evidence-based treatment strategies for weight non-response after sleeve gastrectomy cannot be deduced from the current literature. Prospective studies with well-defined indications, standardised techniques, and strict adherence to outcome measurements are needed.

Bariatric surgery trends and progress in Taiwan: 2010-2021

INTRODUCTION

Taiwan is a leading country regarding bariatric surgery in Asia-Pacific. Since 2010, the Taiwan Society for Metabolic and Bariatric Surgery (TSMBS) has been accountable for the national evolution of bariatric surgery and inaugurated a national database accordingly. This study aimed to analyze the bariatric surgery trends and progress in Taiwan from 2010 to 2021.

MATERIALS AND METHODS

The TSMBS database was collected on the basis of structured inquiries filled out by bariatric surgeons in Taiwan. All patients involving bariatric surgery were included. The data were stratified with the following objectives, including the types of bariatric procedures, demographic characteristics, and perioperative variables. A nationwide database was comprehensively analyzed and evaluated to determine the trends in the applications of the procedure.

RESULTS

Data of 30,026 patients were enrolled. A 2.5-fold increase was observed in bariatric procedures, from 1218 in 2010 to 3005 in 2021. Within 12 years, female accounts for 61.8 %. The revisional rate was 3.40 % during the exploration stage (2010-2013), 2.77 % during the maturity stage (2013-2018), and 5.10 % during the expansion stage (2019-2021). The top five of primary bariatric surgery is sleeve gastrectomy (SG, 63.05 %), gastric clipping surgery (GC, 11.17 %), Roux-en-Y gastric bypass (RYGB, 9.34 %), one anastomosis gastric bypass (OAGB, 8.80 %), and sleeve plus surgery (SG plus, 4.43 %).

CONCLUSION

The trends and progress of Taiwan's bariatric surgery within recent decades are presented in this article. Taiwan's bariatric surgery case number has increased steadily from 2010 to 2021. Amongst all, SG has become the most dominant procedure since 2011 while OAGB takes up second place in 2020.

Combined Nissen Fundoplication and Single Anastomosis Sleeve Ileal Bypass (N-SASI) as a Practical Modality of Bariatric Surgery (Video Report)

Sleeve gastrectomy is one of the most common bariatric procedures because of its simplicity and effectiveness. Gastro-esophageal reflux disease (GERD) symptoms and weight regain after SG are common issues. Roux-en-Y gastric bypass (RYGB) is currently the most promising approach to achieve satisfying weight loss and GERD remission; however, remnant gastric cancer is still a major concern for patients. We present a video case that individualized procedure of Nissen fundoplication, and SASI bypass (N-SASI) was designed and applied to the patient with class III obesity and severe GERD. This is a 37-year-old man with obesity (BMI: 41.8 kg/m², categorized as class III obesity) and associated disease of stage 1 hypertension, hyperlipidemia, obstructive sleep apnea syndrome, and non-alcoholic steatohepatitis as well as severe symptoms of GERD. Esophageal-gastro-duodenal scope revealed GERD grade C, hiatal hernia, and duodenal ulcer. He refused RYGB recommended initially due to serious concern about remnant gastric cancer. We therefore performed Nissen fundoplication for his GERD symptoms and adapted SASI bypass instead of RYGB as the individualized bariatric surgery to achieve the optimal surgical outcome. The postoperative course was smooth, and the patient was discharged on postoperative day 8.

Metabolic surgery in China: present and future

Obesity and its related complications comprise a serious public health problem worldwide, and obesity is increasing in China. Metabolic surgery is a new type of treatment with unique advantages in weight loss and obesity-related metabolic complications. The pathogenesis of obesity is complex and not yet fully understood. Here, we review the current efficacy and safety of metabolic surgery, as well as recent progress in mechanistic studies and surgical procedures in China. The exciting and rapid advances in this field provide new opportunities for patients with obesity and strike a balance between long-term effectiveness and safety.

The Mid-Term Effects of Transit Bipartition with Sleeve Gastrectomy on Glycemic Control, Weight Loss, and Nutritional Status in Patients with Type 2 Diabetes Mellitus: a Retrospective Analysis of a 3-Year Follow-up

BACKGROUND

Metabolic surgery is an effective treatment method for glycemic control and weight loss in obese patients with type 2 diabetes mellitus (T2DM). This study aimed to present the mid-term metabolic effects and weight loss results of the patients with T2DM who underwent transit bipartition with sleeve gastrectomy (TB-SG).

METHODS

A total of 32 obese patients with T2DM who underwent TB-SG were included in the study. The T2DM remission status after surgery was evaluated. The postoperative glycemic variables, weight loss, lipid profile, and nutritional profile were also compared with the baseline values.

RESULTS

At 36 months after surgery, T2DM remission occurred in 27 patients (84.3%) and the mean BMI decreased from 44.70 ± 9.34 to 29.75 ± 2.19 kg/m². The percentage of total weight loss (TWL) and excess weight loss (EWL) was 33.84% and 77.19%, respectively. The mean LDL values significantly decreased compared to baseline; however, the mean HDL did not significantly differ. No significant difference was observed regarding the mean albumin, vitamin B12, and folic acid levels.

CONCLUSION

TB-SG procedure seems promising in terms of T2DM remission and weight loss with less malnutrition and vitamin deficiency in treating obese patients with T2DM.

Is the Sleeve Gastrectomy Sufficient or Does it Require Additional Surgical Procedures?

Laparoscopic sleeve gastrectomy is a relatively simple procedure and has become the most well-known bariatric surgical procedure in Korea and Western countries. However, this procedure has several disadvantages in terms of long-term weight loss and metabolic disease control. Laparoscopic sleeve gastrectomy and additional bypass (sleeve plus) procedures were recently introduced into bariatric surgery in order to combine the physiologic advantages of pyloric-saving reconstruction and the bypass effect. A sleeve gastrectomy was performed first, followed by a bypass procedure. This review describes sleeve plus procedures reported in the literature and compares their outcomes with the most frequently performed techniques.

Three-Year Outcomes of Sleeve Gastrectomy Plus Jejunojejunal Bypass: a Retrospective Case-Matched Study with Sleeve Gastrectomy and Gastric Bypass in Chinese Patients with BMI ≥35 kg/m2

BACKGROUND

Sleeve gastrectomy plus jejunojejunal bypass (SG+JJB) is a novel bariatric procedure. In this study, we compared the 3-year outcomes of SG+JJB to those of sleeve gastrectomy (SG) and gastric bypass (RYGB).

METHODS

This retrospective study included 113 patients (SG, N=31; RYGB, N=33; SG+JJB, N=49) with a preoperative BMI≥35 kg/m². Among them, 31 pairs of patients who underwent SG+JJB/SG and 33 pairs who underwent SG+JJB/RYGB were matched by sex, age (±2 years), and BMI (±2 kg/m²). Postoperative weight loss, diabetes remission, and patient complaints at the 3-year follow-up were compared.

RESULTS

SG+JJB yielded higher 3-year total weight loss (TWL) than SG alone (35.5±9.1% vs 31.5±7.3%, P=0.031) and equivalent 3-year %TWL to RYGB. The diabetes remission rate of SG+JJB was similar to that of SG or RYGB. SG+JJB resulted in a higher incidence of malodorous flatus than SG (25.8% vs 0, P<0.05). Compared to RYGB, SG+JJB resulted in a higher incidence of postoperative de novo gastroesophageal reflux disease (GERD) symptoms (30.3% vs 0, P<0.05).

CONCLUSIONS

In the present study, we found that SG+JJB yielded higher weight loss than SG and similar weight loss to RYGB at the 3-year follow-up. SG+JJB increased the risk of malodorous flatus compared to SG and de novo GERD symptoms compared to RYGB.
