Influence of referral type and sociodemographic factors on completion of bariatric surgery.

Background: The impact of referral type and socioeconomic status on completion of the bariatric surgery process is not well understood.

Objectives: This study aims to 1) describe how sociodemographic characteristics influence referral type and 2) identify predictors of completion of surgery.

Setting: Large multihospital health care system, including a large academic medical center.

Surgeon variability in repair of hiatal hernia at the time of bariatric surgery.

Background: Hiatal hernia (HH) is estimated to affect between 20 and 50% of patients undergoing bariatric surgery. However, there is no consensus regarding the preoperative assessment and intraoperative repair of HH. The aim of this study was to evaluate the variation in surgeon assessment and repair of HH during bariatric surgery across a multi-hospital healthcare system.

Increased bleeding risk with enoxaparin venothromboembolism prophylaxis compared with heparin in patients undergoing bariatric surgery.

Background: Perioperative venothromboembolism (VTE) chemoprophylaxis is an established tenant of bariatric surgery; however, there is little comparative data to guide medication choice. The objective of this study was to determine if a change in VTE prophylaxis from heparin to enoxaparin was associated with differing rates of postoperative bleeding and VTE occurrence after bariatric surgery.

Methods: This retrospective cohort study included patients 18 years or older who underwent primary bariatric surgery (sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB)) at a single institution between March 2012 and December 2021.

Identifying hiatal hernia with impedance planimetry during esophageal distension testing.

Introduction: Functional luminal imaging probe (FLIP) Panometry evaluates the esophageal response to distension involving biomechanics and motility. We have observed that hiatus hernia (HH) is evident during FLIP studies as a separation between the crural diaphragm (CD) and lower esophageal sphincter (LES) like what is seen with high-resolution manometry (HRM). The aim of this study was to compare FLIP findings to endoscopy and HRM in the detection of HH.
