Endoscopic retrograde cholangiopancreatography (ERCP) has become the mainstay of therapy for pancreatobiliary diseases. While ERCP is safe and highly effective in the general population, the procedure remains challenging or impossible in patients with surgically altered anatomy (SAA). Endoscopic ultrasound (EUS) allows transmural access to the bile or pancreatic duct (PD) prior to ductal drainage using ERCP-based techniques. Also known as endosonography-guided cholangiopancreatography (ESCP), the procedure provides multiple advantages over overtube-assisted enteroscopy ERCP or percutaneous or surgical approaches. However, the procedure should only be performed by endoscopists experienced in both EUS and ERCP and with the proper tools. In this review, various EUS-guided diagnostic and therapeutic drainage techniques in patients with SAA are examined. Detailed step-by-step procedural descriptions, technical tips, feasibility, and safety data are also discussed.

Background: Despite initial successful weight loss, some patients may experience weight regain following Roux-en-Y gastric bypass (RYGB). Objective: To assess the impact of weight regain on bariatric patients’ quality of life (QoL). Methods: This was a prospective cross-sectional study. Fifty-six consecutive RYGB patients were recruited and divided into weight-regain and weight-stable cohorts. QoL was assessed using the Bariatric Quality of Life (BQL) questionnaire. The BQL Index scores of the weight-regain and weight-stable groups were compared using Student’s t-test. Additionally, the BQL Index score of the weight-regain group was compared with that of historical prebariatric patients. Predictors of BQL were assessed using univariate and multivariate linear regression analyses. Results: Of 56 RYGB patients, 41 (73%) had weight regain. On average, patients had body mass index (BMI) of 37 ±7.5 kg/m2 and gained 34 ±26% of maximal weight initially lost. Weight-regain patients had lower BQL Index scores than weight-stable patients (44.8±6 vs 53±7, p<0.001). Patients with weight regain had similar BQL Index scores as the prebariatric patients despite lower BMI (BMI of 39.7±6.8 vs 47.2±7.6, p<0.05; BQL Index of 44.8±6 vs 41.6±10.4, p=0.144, respectively). Years from RYGB, BMI and amount of weight regain were associated with BQL Index on a univariate analysis (β=−0.55,−0.52, −0.7; p<0.0001). Only weight regain was a significant predictor of BQL on a multivariate analysis (β =−0.56; p=0.001). Conclusion: Weight regain had a negative impact on bariatric patients’ QoL. Patients who regained at least 15% of maximal weight lost appeared to have as low QoL as those who had not undergone bariatric surgery despite a lower BMI.
