“…The one anastomosis gastric bypass (OAGB), also known as single anastomosis gastric bypass or mini gastric bypass, is an effective, safe and simple alternative of LRYGB. Moreover, it has a significant reduction of technical complexity, shorter operative time and a potential reduction in morbidity and mortality [ 14 , 15 ]. Although the laparoscopic surgical approach has the advantage of less postoperative pain [ 16 ], patients undergoing laparoscopic bariatric surgery still require efficient analgesia to prevent postoperative complications.…”

“…Effective pain control reduces the risk of postoperative complications such as pneumonia or atelectasis by enhancing deep breathing, deep vein thrombosis and pulmonary embolism, by encouraging early mobilization [ 17 ]. Furthermore, the effective control of perioperative pain helps prevent its transition to chronic pain [ 14 ]. A restriction concerning the efficient postoperative analgesia of obese patients is that these patients frequently suffer from comorbidities such as obstructive sleep apnea and other forms of sleep-disordered breathing, making the use of systemic opioids at the early postoperative period very challenging [ 18 ].…”

Uncontrolled postoperative pain and prolonged immobilization after bariatric surgery have been associated with increased postoperative complications and prolonged hospitalization. The aim of our study was to evaluate the postoperative pain that follows bariatric surgery and identify any psychological factors that may affect the early postoperative perception of pain. The study included 100 patients with obesity (women, n = 61; age 37.4 ± 9.9 years, mean ± standard deviation; Body Mass Index (BMI) 47.6 ± 6.5 kg/m2) who underwent bariatric surgery. Preoperative anxiety and depression were evaluated by the Hospital Anxiety and Depression Scale (HADS), and the quantitative and qualitative dimension of early postoperative pain were evaluated by the McGill Pain Questionnaire Short Form (MPQ-SF). Furthermore, the postoperative analgesia protocol was recorded for each patient. Pain declined gradually during the first 24 h postoperative. Although preoperative anxiety had no correlation with the overall pain of postoperative Day 0, patients with a higher level of preoperative anxiety had significantly more intense and more unpleasant pain at 1 h post operation. In addition, depression influences both the intensity and unpleasantness of pain at different time points (1 h, 4 h and 24 h postoperative). Preoperative pain correlated with educational level, but not with age, BMI, gender, marital status, smoking and surgery type. In conclusion, preoperative anxiety and depression influence the early postoperative pain after bariatric surgery, and their preoperative identification is of major importance to enhance the implementation of fast-track postoperative protocols to prevent complications and prolonged hospitalization.

“…In the present day, it is observed that bariatric surgery is a good therapeutic modality for the treatment of morbid obesity 4 . In several prominent studies, such as those of Buchwald 3 , Schauer 20 and Sugerman 22 , it can be noted that the improvement of comorbidities, together with the loss of excess weight, achieves good results with it.…”

Introduction: Obesity is a disease of high prevalence in Brazil and in the world, and bariatric surgery, with its different techniques, is an alternative treatment. Objective: To compare techniques: adjustable gastric band (AGB), sleeve gastrectomy), Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) analyzing leaks, bleeding, death, weight loss, resolution of type 2 diabetes, systemic arterial hypertension, dyslipidemia and obstructive sleep apnea. Methods: Were selected studies in the PubMed database from 2003 to 2014 using the descriptors: obesity surgery; bariatric surgery; biliopancreatic diversion; sleeve gastrectomy; Roux-en-Y gastric bypass and adjustable gastric banding. Two hundred and forty-four articles were found with the search strategy of which there were selected 116 studies through the inclusion criteria. Results: Excess weight loss (EWL) after five years in AGB was 48.35%; 52.7% in SG; 71.04% in RYGB and 77.90% in BPD. The postoperative mortality was 0.05% in the AGB; 0.16% on SG; 0.60% in RYGB and 2.52% in BPD. The occurrence of leak was 0.68% for GBA; 1.93% for SG; 2.18% for RYGB and 5.23% for BPD. The incidence of bleeding was 0.44% in AGB; 1.29% in SG; 0.81% in RYGB and 2.09% in BPD. The rate of DM2 resolved was 46.80% in AGB, 79.38% in SG, 79.86% in RYGB and 90.78% in BPD. The rate of dyslipidemia, apnea and hypertension resolved showed no statistical differences between the techniques. Conclusion: The AGB has the lowest morbidity and mortality and it is the worst in EWL and resolution of type 2 diabetes. The SG has low morbidity and mortality, good resolution of comorbidities and EWL lower than in RYGB and BPD. The RYGB has higher morbidity and mortality than AGB, good resolution of comorbidities and EWL similar to BPD. The BPD is the worst in mortality and bleeding and better in EWL and resolution of comorbidities.

“…All procedures were laparoscopically performed by the same surgical team led by one of the authors of this study following a previously described technique (17) . The main features were: a vertical gastric pouch of about 15-18 cm (50-150 mL) and an omega-loop isoperistaltic antecolic stapler side-to-side 3-cm gastrojejunostomy performed 200 cm further from the Treitz ligament (biliopancreatic limb), with or without the placement of a 6.5-cm silicone ring around the gastric pouch.…”

BACKGROUND: The influence of the placement of a band on the outcomes of one anastomosis gastric bypass (OAGB) has not been appropriately studied yet. OBJECTIVE: To compare early weight loss and glucose metabolism parameters following banded versus non-banded OAGB. METHODS: A prospective randomized study, which evaluated 20 morbidly obese individuals who underwent banded and non-banded OAGB and were followed-up for three months. Weight loss (percentage of excess weight loss - %EWL and percentage of body mass index loss - %BMIL) and glucose metabolism outcomes (glucose, insulin and homeostasis model assessment - HOMA) were compared. RESULTS: The banded group presented a significantly higher %EWL at one month (29.6±5.5% vs 17.2±3.4%; P<0.0001) and two months post-surgery (46±7% vs 34.2±9%; P=0.004544), as well as a significantly higher %BMIL at one month (9.7±1.1% vs 5.8±0.8%; P<0.0001), two months (15±1.4% vs 11.5±2.1; P=0.000248), and three months (18.8±1.8% vs 15.7±3.2%; P=0.016637). At three months, banded OAGB led to significant decreases of insulin (14.4±4.3 vs 7.6±1.9; P=0.00044) and HOMA (3.1±1.1 vs 1.5±0.4; P=0.00044), whereas non-banded OAGB also led to significant decreases of insulin (14.8±7.6 vs 7.8±3.1; P=0.006) and HOMA (3.2±1.9 vs 1.6±0.8; P=0.0041). The percent variation of HOMA did not significantly differ between banded and non-banded OAGB (P=0.62414); overall, the percent variation of HOMA was not correlated with %EWL (P=0.96988) or %BMIL (P=0.82299). CONCLUSION: Banded OAGB led to a higher early weight loss than the standard technique. Banded and non-banded OAGB led to improvements in insulin resistance regardless of weight loss.
