Sleeve to gastric bypass conversion: a multiinstitutional study of 217 patients.

Background: Revision of a sleeve gastrectomy (SG) to a Roux-en-Y gastric bypass (RYGB) is indicated for gastroesophageal reflux disease (GERD) and for weight recurrence. Existing literature is conflicting and lacks long-term follow-up.

Objectives: To evaluate the resolution of GERD and additional weight loss after conversion of SG to RYGB.

How to manage peritoneal dialysis in patients undergoing bariatric surgery? A case series from a single academic center.

Background: Bariatric surgery has gained significant attention as a potential approach for improving access to kidney transplantation (KT) in dialysis-dependent patients with severe obesity. However, there is lack of literature on how to manage peritoneal dialysis (PD) in patients with severe obesity undergoing bariatric surgery. This study aims to describe the protocol used in this specific patient population at a single academic center, focusing on the important role of the multidisciplinary team in managing this vulnerable group of patients.

Machine learning in predicting cauda equina imaging outcomes- a solution to the problem.

Purpose: Cauda Equina Syndrome (CES) is a rare surgical emergency. The implications for loss of quality of life through delayed management are high, though no clinical symptom is pathognomonic in its diagnosis. We describe how machine learning based algorithms can be used in triaging patients with suspected CES (CES-S).

Ambulatory bariatric surgery: a prospective single-center experience.

Background: Ambulatory bariatric surgery has recently gained interest especially as a potential way to improve access for eligible patients with severe obesity. Building on our previously published research, this follow-up study delves deeper in the evolving landscape of ambulatory bariatric surgery over a 3-year period, focusing on predictors of success/failure.

Methods: In a prospective single-center follow-up study, we conducted a descriptive assessment of all eligible patients as per our established protocol, who underwent a planned same-day discharge (SDD) primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 03/01/2021 and 02/29/2024.

Methods: This is a follow-up report from a single-institution prospective cohort study comparing long-term outcomes of SADI-S versus DS both as one- and two-stage procedures (ClinicalTrials.

Predictors of post-discharge pain and satisfaction with pain management after laparoscopic bariatric surgery: a prospective cohort study.

Background: Pain management after bariatric surgery remains challenging given the risk for analgesia-related adverse events (e.g., opioid use disorder, marginal ulcers).

Management of abdominal wall hernias in patients with severe obesity.

Obesity is a risk factor for abdominal wall hernia development and hernia recurrence. The management of these two pathologies is complex and often entwined. Bariatric and ventral hernia surgery require careful consideration of physiologic and technical components for optimal outcomes.

Prescription and consumption of opioids after bariatric surgery: a multicenter prospective cohort study.

Introduction: In the current opioid crisis, bariatric surgical patients are at increased risk of harms related to postoperative opioid overprescribing. This study aimed to assess the extent to which opioids prescribed at discharge after bariatric surgery are consumed by patients.

Methods: This multicenter prospective cohort study included adult patients (≥ 18yo) undergoing laparoscopic bariatric surgery.

Ambulatory sleeve gastrectomy: a prospective feasibility and comparative study of early postoperative morbidity.

Background: Given its short procedure time and low morbidity, there is enthusiasm to perform sleeve gastrectomy (SG) in an outpatient setting. However, most relevant studies include an overnight stay at a medical facility (≤ 24-h). Hence, we investigated the feasibility and safety of a same-day discharge (SDD) protocol for laparoscopic SG.

Outcomes of kidney transplant recipients who underwent pre-transplant bariatric surgery for severe obesity: a long-term follow-up study.

Background: Kidney transplantation (KT) is the preferred therapy for end-stage renal disease (ESRD). While a major cause for ESRD, obesity is also a key obstacle to candidacy for KT. Bariatric surgery, particularly sleeve gastrectomy (SG), is increasingly used to improve access to KT in patients with obesity, but the literature especially on outcomes post-KT remains lacking.

Lumbar Fixation Using the Cortical Bone Trajectory Fixation: A Single Surgeon's Experience With 3-Year Follow-up.

Background: Pedicle screw fixation with a cortical bone trajectory (CBT) has emerged as an effective alternative to traditional techniques of lumbar fusion, especially in osteoporotic patients. The proposed benefits of CBT screws include a stronger grip in the elderly and osteoporotic population and low surgical morbidity. We present a prospective study with a 3-yr follow-up of 80 patients operated on by the same surgeon.

Long-term Impact of Bariatric Surgery on Major Adverse Cardiovascular Events in Patients with Obesity, Diabetes and Hypertension: a Population-level Study.

Background: The literature on long-term impact of bariatric/metabolic surgery on incidence of major adverse cardiovascular events (MACE) in patients with obesity and metabolic syndrome is still lacking. We aimed to evaluate the long-term relationship between metabolic surgery and MACE in such patients.

Methods: In a population-based cohort study, we compared all patients with obesity, diabetes mellitus (DM) and/or hypertension (HTN), who underwent bariatric surgery in Quebec, Canada during 2007-2012, with matched controls with obesity.

Predictive Factors of Cholelithiasis After Prophylactic Administration of Ursodeoxycholic Acid Following Laparoscopic Bariatric Surgery: Tehran Obesity Treatment Study.

Purpose: Cholelithiasis is a well-known consequence of obesity as well as rapid weight loss especially after bariatric surgery. A routine postoperative course of ursodeoxycholic acid (UDCA) is recommended as a prophylactic measure against gallstone formation. However, the efficacy of UDCA after bariatric surgery and predictors of cholelithiasis despite prophylaxis are not well understood.

Successful surgical weight loss with laparoscopic sleeve gastrectomy for morbid obesity prior to kidney transplantation.

Morbid obesity in kidney transplant (KT) candidates is associated with increased complications and graft failure. Multiple series have demonstrated rapid and significant weight loss after laparoscopic sleeve gastrectomy (LSG) in this population. Long-term and post-transplant weight evolutions are still largely unknown.

Esophageal cancer after sleeve gastrectomy: a population-based comparative cohort study.

Background: Sleeve gastrectomy (SG) is the most common bariatric surgery; however, this approach may induce gastroesophageal reflux disease (GERD). Both obesity and GERD are independent risk factors for esophageal cancer, however the impact of SG on risk of esophageal cancer remains unknown.

Objective: To evaluate the risk of esophageal cancer after reflux-prone bariatric surgery.

Diastematomyelia type I associated with intramedullary lipoma and dermoid cyst.

Dysraphic entities like diastematomyelia are not uncommon. However, the co-existence of split cord malformation with two pathologically different lesions on the same hemicord is extremely rare. We report a case of a young child who presented with an unusual combination of diastematomyelia, intramedullary lipoma, and dermoid cyst.

Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S): short-term outcomes from a prospective cohort study.

Background: Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of the classic duodenal switch (DS). These modifications are intended to address concerns about DS, including malnutrition, longer operative times, and technical challenges, while preserving the benefits.

Objectives: To evaluate safety and outcomes of SADI-S as it compares to classic DS procedure.

Short-term outcomes of revisional surgery after sleeve gastrectomy: a comparative analysis of re-sleeve, Roux en-Y gastric bypass, duodenal switch (Roux en-Y and single-anastomosis).

Background: Sleeve gastrectomy (SG) is the most common primary bariatric surgery. Long-term, up to 20% of patients may need revisional surgery. We aimed to evaluate the short-term outcomes of various revisional bariatric surgeries after a failed primary SG.

Surgeon and hospital volume outcomes in bariatric surgery: a population-level study.

Background: Outcomes after bariatric surgery are tied to surgical volume; however, this relationship is not clearly established for each procedure.
