“…In summary, our study shows that RYGB has a high rate of long-term successful weight loss and obesity associated comorbidity improvement, reinforcing previous similar reports [11,12,15,[37][38][39][40][41][42]. The long-term morbidity was overall low, despite there is a possibility of complications that may affect quality of life, such as dumping syndrome, internal hernias, marginal ulcers or severe vitamin deficiencies, which have been appointed as reasons for progressive abandonment of the RYGB.…”

Purpose The rate of weight regain after Roux-en-Y Gastric Bypass (RYGB) can hamper the procedure long-term efficacy for obesity treatment and related comorbidities. To evaluate the rate of weight loss and comorbidity remission failure 10 years or more after RYGB surgery. Materials and methods Retrospective observational cohort study. Patients submitted to RYGB for obesity treatment at a single centre with 10 years or more after surgery underwent a clinical reassessment. Results Among the subjects invited for clinical revaluation (n = 585), only those who performed RYGB and attended the hospital visit were included in the study (n = 281). The pre-operative mean body mass index (BMI) was 44.4 ± 6.1 kg/m2. Mean post-operative time was 12.2 ± 1.1 years. After surgery, mean BMI was significantly lower 33.4 ± 5.8 kg/m2 (p < 0.0001), 29.5% with a BMI < 30 kg/m2. Mean Total Weight Lost (%TWL) was 24.3 ± 11.4%, reaching a %TWL ≥ 20% in 70.1% with a mean %TWL of 30.0 ± 7.0%. Co-morbidities remission rate was 54.2% for type 2 diabetes, 34.1% for hypertension, 52.4% for hyperlipidemia and 50% for obstructive sleep apnea. Early complications rate was 13.2% and revision surgery occurred in 2.8% of patients. Four patients died of RYGB complications within the first 90 days after surgery. Conclusion RYGB has a high rate of long-term successful weight loss and obesity-associated comorbidity improvement. Weight loss failure requiring revision surgery occurs in a small proportion of patients. Our data confirms the long-term effectiveness of RYGB as primary bariatric intervention. Graphical abstract

“…On the other hand, longer and more solid follow-up data are available for RYGB (approximately 29% of all bariatric procedures) (28), which is still considered the 'gold standard' bariatric procedure by several authors (1, 2, 4, 5, 29). RYGB guarantees sustained weight loss results in the majority of patients, with a low rate of long-term morbidity/adverse events (30,31). OAGB is a less "mature" bariatric surgical procedure, now representing 6.7% of bariatric interventions worldwide (26).…”

Background/Aim: Long-term gastroesophageal reflux (GERD) after gastric bypass for obesity is underestimated. The present study aimed to evaluate the rate of treated GERD and the factors influencing it in a cohort of patients who underwent gastric bypass. Patients and Methods: Patients who underwent one-anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) as a primary bariatric procedure between 2010 and 2011 at a French private referral center were included in the study. The primary endpoint was the 10-year prevalence of GERD. Results: In total, 422 patients underwent RYGB and 334 underwent OAGB with a biliopancreatic limb of 150 cm. The mean age was 38.9±11.3 years, and 81.6% of patients were female; the mean preoperative body mass index was 42.8±5 kg/m 2 . Preoperative GERD was diagnosed in 40.8% of patients in the total cohort, 31.7% in the RYGB group versus 49.1% in the OAGB group (p<0.0001). At 10-year followup, the rate of GERD was 21.1%, with no difference between the two groups. Remission of preoperative GERD and de novo GERD were comparable between the two types of bypass. Surgery for GERD resistant to medical treatment was more frequent in the OAGB group. At multivariate analysis, factors significantly correlated with long-term GERD were: Preoperative GERD, total weight loss at 120 months <25%, glycemic imbalances and anastomotic ulcers. Conclusion: Identification and correction of modifiable factors may help reduce the incidence of long-term GERD.

“…Although less technically demanding procedures are available, RYGB is still considered the preferable procedure in some areas worldwide. Several reports demonstrated the efficacy of RYGB and its durability from a weight-loss standpoint over 10 years, with a total weight reduction of >25% in 61-71% of patients [70][71][72]. Despite that, weight regain can happen regardless of the type of weight-reducing surgery.…”

Bariatric Surgery - Past and Present

Metabolic surgery is considered a valuable tool in treating obesity compared to the non-surgical approach. Its effectiveness is evident in the form of weight loss, eliminating obesity-related comorbidities, and improving quality of life. Hence, the rate of metabolic surgery conducted worldwide has risen dramatically, parallel to the increasing rates of obesity. Unfortunately, there are drawbacks to metabolic surgeries. Weight regain/insufficient weight loss is feared by the patient and bariatric surgeon and can occur with nonadherence to a healthy lifestyle and dietary habits. Long-term complications related to metabolic surgery are possible following any metabolic surgery (e.g., chronic reflux, malnutrition, and fistula). Revisional surgery is the most effective approach to combat these drawbacks, and therefore a bariatric surgeon should be familiar with it. This chapter will discuss the indication of revisional surgery, the preoperative workup, the surgical techniques, and the outcome of revisional surgery. The chapter will focus on the most commonly performed metabolic surgery, that is, laparoscopic adjustable gastric band, laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic one anastomosis gastric bypass. By the end of this chapter, the reader will be able to: (1) Define metabolic surgery failure and indications of the revision. (2) Be able to approach the patient preoperatively and formulate a plan. (3) Be knowledgeable about the main operative steps. (4) Be aware of the predicted outcome of revisional surgery.
