Vertical Banded Gastroplasty Converted to Roux-en-Y Gastric Bypass: Little Impact on Nutritional Status after 5-Year Follow-up

Abstract

More than 50% of VBGs failed after 2-year follow-up. Patients converted to RYGBP maintained mean EWL 73% at 5 years. The only significant nutritional deficiencies were iron and vitamin B(12), in patients converted to RYGBP.

Laparoscopic revisional bariatric surgery: myths and facts

“…As a result, primary obesity surgery has been performed increasingly all over the world [5, 6, 10]. There is no ''perfect surgical technique'' for treating morbidly obese patients that achieves 100% excellent results, and probably, more revisional bariatric procedures should be necessary.The main causes for revisional bariatric procedures are regaining of weight, inadequate weight loss, late complications, or loss of quality of life.Vertical banded gastroplasty has a 29% to 56% incidence of long-term revision [18,19,23,26]. Gastric banding is associated with a revison rate of 3.5% to 60% [4, 8, 9, 22, 27], and gastric bypass has a 3% to 13% incidence of revisional procedures, tending to the lower end [2,15,23].…”

Although bileopancreatic diversion has been performed for a large number of patients, there is little data about revisional procedures [25].Although revisional bariatric surgery, traditionally performed by laparotomy, usually is technically demanding and associated with increased morbidity rates, as compared with primary procedures, most authors believe that the benefits are definitely worth the risk [1,2,16,29].The use of laparoscopy in primary bariatric surgery has decreased operative complications and enabled the maintenance of good long-term results [21,23,28]. To date, laparoscopic bariatric surgery is the standard primary surgical treatment for morbid obesity [7,21].…”

Correction to: Reoperative Bariatric Surgery: a Systematic Review of the Reasons for Surgery, Medical and Weight Loss Outcomes, and Relevant Behavioral Factors

“…Increased risk of metabolic/nutritional complications occurs particularly in malabsorptive surgeries (e.g., RYGB, biliopancreatic diversion with a duodenal switch) [43], as these procedures modify the functional anatomy of the gastrointestinal tract and the absorption of nutrients. Research has suggested that approximately 20% of patients submitted to distal RYGB reoperation develop nutritional complications [19], including low levels of vitamin B 12 , after conversion to RYGB [41], and also after conversion to biliopancreatic diversion with a duodenal switch [42]. The decrease in iron levels [41], as well as protein deficits, after conversion to RYGB has also been reported.…”

The decrease in iron levels [41], as well as protein deficits, after conversion to RYGB has also been reported. Further research is needed to investigate if nutritional complications after reoperative surgeries are similar or increase when compared to primary interventions, particularly considering the expected accentuated weight loss and the more invasive procedures.…”
