Clinical and financial outcomes of per-oral endoscopic myotomy compared to laparoscopic heller myotomy for treatment of achalasia.

Background: Previous studies analyzing short-term outcomes for per-oral endoscopic myotomy (POEM) have shown excellent clinical response rates and shorter operative times compared to laparoscopic Heller myotomy (LHM). Despite this, many payors have been slow to recognize POEM as a valid treatment option. Furthermore, comparative studies analyzing long-term outcomes are limited.

Laparoscopic revision paraesophageal hernia repair: a 16-year experience at a single institution.

Background: Laparoscopic paraesophageal hernia repair (PEHr) is a safe and effective procedure for relieving foregut symptoms associated with paraesophageal hernias (PEH). Nonetheless, it is estimated that about 30-50% of patients will have symptomatic recurrence requiring additional surgical intervention. Revision surgery is technically demanding and may be associated with a higher rate of morbidity and poor patient-reported outcomes.

The contribution of the immune system to genitourinary fibrosis.

Fibrotic diseases of the genitourinary tract are devastating and incompletely understood pathologies. These diseases include urethral and ureteral strictures, retroperitoneal fibrosis, and Peyronie's disease. They can contribute to obstructive uropathy and sexual dysfunction.

A comparative evaluation of robotic and laparoscopic Roux-en-Y gastric bypass: a critical evaluation on the impact of postoperative pain and opioid requirements.

Introduction: The benefits of minimally invasive surgery using laparoscopy on postoperative pain and opioid use are well established. Our goal was to determine whether patients who underwent Roux-en-Y gastric bypass using a robotic approach (RA-RYGB) had lower postoperative pain and required less opioids than those undergoing laparoscopic Roux-en-Y gastric bypass (L-RYGB). Secondary outcomes evaluated included length of stay, operative time, and readmissions.

The purpose of the current study is to determine whether urinary catheter use in patients undergoing Roux-en-Y gastric bypass (RYGB) procedures has an effect on postoperative outcomes.

Methods: An institutional database was utilized to identify adult patients undergoing primary minimally invasive RYGB surgery.

Asymptomatic Cholelithiasis and Bariatric Surgery: a Comprehensive Long-Term Analysis of the Risks of Biliary Disease in Patients Undergoing Primary Roux-en-Y Gastric Bypass.

Purpose: Currently, there is little consensus on management of the in situ gallbladder of patients undergoing gastric bypass. Our aim was to evaluate outcomes of selective concomitant cholecystectomy (CCY) and long-term biliary outcomes after Roux-en-Y gastric bypass (RYGB).

Materials And Methods: We performed a retrospective analysis of patients undergoing laparoscopic RYGB (LRYGB) between 2008 and 2018.

A 3-Year MBSAQIP propensity-matched analysis of Roux-en-Y gastric bypass with concomitant cholecystectomy: Is the robotic or laparoscopic approach preferred?

Background: The primary objective of this study was to compare outcomes of patients undergoing minimally invasive RYGB (MIS/RYGB) versus MIS/RYGB with concomitant Cholecystectomy (CCY). A secondary objective was to compare the outcomes for laparoscopic RYGB (LRYGB) and robotic RYGB (RRYGB) with concomitant CCY.

Methods: Outcomes of 117,939 MIS/RYGB with and without CCY were propensity-matched (Age, Gender, BMI, Comorbidities), 10:1, using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database from 2015-2017.

Emergency department overutilization following cholecystectomy and inguinal hernia repair.

Background: Emergency Department (ED) utilization following general surgery procedures is poorly understood and places immense strain on the healthcare system. Inefficient ED utilization is responsible for up to $38 billion in wasteful spending annually. Nearly 56% of ED visits may be avoidable.

The Longitudinal Efficiency of Robotic Surgery: an MBSAQIP Propensity Matched 4-Year Comparison of Robotic and Laparoscopic Bariatric Surgery.

Background: The objective of this study was to examine the MBSAQIP database to assess efficiency trends and perioperative outcomes in robotic bariatric surgery.

Methods: Robotic (RA) and laparoscopic (L) sleeve gastrectomy (SG) and gastric bypass (RYGB) were compared using the 2015-2018 MBSAQIP Participant Use Data Files. Patients were propensity matched 1:1 based on sex, body mass index, assistant, and previous obesity or foregut surgery.

Cutting-Edge Evaluation of Male Infertility.

A male factor is a contributor in 50% of cases of infertility. Although assisted reproductive techniques can often bypass the need to improve semen parameters, the evaluation of the infertile man remains critical. Current methods for evaluating the infertile man are discussed, beginning with the basic workup that all suspected infertile men should undergo, followed by subsequent evaluation steps.

Peyronie's disease: is it genetic or not?

Peyronie's disease (PD) is a devastating disease that affects up to 13% of adult men. While trauma to the erect penis is common prior to onset, it is clear that trauma alone is not sufficient to cause PD. Over the past 40 years, multiple lines of evidence have pointed to a genetic factor that predisposes some men to develop PD.

Overall outcomes of laparoscopic-assisted ERCP after Roux-en-Y gastric bypass and sphincter of Oddi dysfunction subgroup analysis.

 Biliary access following Roux-en-Y gastric bypass (RYGB) anatomy presents a significant challenge. Long-term outcomes of laparoscopic-assisted trans-gastric ERCP (LA-ERCP) including sphincter of Oddi dysfunction (SOD) subtypes have not been thoroughly examined. Our study aims to present our overall outcomes of trans-gastric LAERCP and examine a significant subgroup of patients with SOD after RYGB.

Long-Acting Somatostatin Analogue Safety Monitoring Protocol for Outpatients With Neuroendocrine Tumors.

Somatostatin analogues (SSAs) are widely used in the long-term treatment of neuroendocrine tumors (NETs) and have a relatively favorable safety profile. However, SSAs are associated with specific side effects that are important to monitor. Currently, there is no standardized safety monitoring protocol for health-care professionals to use as a reference when initiating patients on long-acting SSAs.

First assistant impact on early morbidity and mortality in bariatric surgery.

Background: The future of bariatric surgery depends largely on how effectively residents and fellows are trained. The challenge is to assure patient safety during training. Our study compares the impact of first assistants on patient outcomes after Roux-en-Y gastric bypass and sleeve gastrectomy.

Penile Rehabilitation: The "Up"-date.

Purpose Of Review: The purpose of this review is to review the penile rehabilitation literature published since the beginning of 2017. Specific emphasis was placed on determining how the new findings increase our understanding of the mechanisms leading to recovery of erectile function after pelvic surgery and to identify potential focus areas for future studies.

Recent Findings: A meta-analysis of penile rehabilitation after prostatectomy was published in early 2017 reporting that PDE-5 inhibitors, intracavernosal injection (ICI) therapy and vacuum erection devices (VED) improved erectile function; however, the benefit was not observed after a washout period.

Where are we going with gene screening for male infertility?

Male infertility is a heterogenous disease process requiring the proper functioning and interaction of thousands of genes. Given the number of genes involved, it is thought that genetic causes contribute to most cases of infertility. Identifying these causes, however, is challenging.

Equivalent Peri-Operative Outcomes for Laparoscopic Roux-En-Y Gastric Bypass Patients Discharged on Post-Operative Day One.

Background: Previous studies have evaluated the safety of post-operative day one (POD #1) discharge after laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery. Few studies, however, have evaluated the impact of a standardized POD #1 discharge pathway on peri-operative outcomes. This study aims to evaluate peri-operative outcomes after implementation of an enhanced recovery pathway for RYGB patients.
