Introduction: The routine collection of patient-reported outcome measures (PROMs) promises to improve patient care. However, in colorectal surgery, PROMs are uncommonly collected outside of clinical research studies and rarely used in clinical care. We designed and implemented a quality improvement project with the goals of routinely collecting PROMs and increasing the frequency that PROMs are utilized by colorectal surgeons in clinical practice.

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare cause of chronic colonic ischemia characterized by intimal smooth muscle proliferation and luminal narrowing of the small to medium sized mesenteric veins. It predominantly affects the rectosigmoid colon in otherwise healthy, middle-aged males. Definitive diagnosis and treatment are surgical; however, patients are frequently misdiagnosed, which often results in a protracted clinical course.

Background: Recent literature has demonstrated that hemodynamic instability in the intraoperative period places patients at risk of poor outcomes. Furthermore, recent studies have reported that stroke volume optimization and protocolized hemodynamic management may improve perioperative outcomes, especially surgical site infection (SSI), in certain high-risk populations. However, the optimal strategy for intraoperative management of all elective patients within an enhanced recovery program remains to be elucidated.

Objective: This study aims to characterize the extent of geographic variation in elective sigmoid resection for diverticulitis and to identify factors associated with observed variation.

Introduction: National guidelines for treatment of recurrent diverticulitis fail to offer strong recommendations for or against surgical intervention. We hypothesize that healthcare market factors will be significantly associated with geographic variation in colon resection for diverticulitis, a discretionary surgical intervention.

Surgical care episodes place opioid-naïve patients at risk for transitioning to new persistent postoperative opioid use. With one of the central principles being the application of multimodal pain interventions to reduce the reliance on opioid-based medications, enhanced recovery pathways provide a framework that decreases perioperative opioid use. The fourth Perioperative Quality Initiative brought together a group of international experts representing anesthesiology, surgery, and nursing with the objective of providing consensus recommendations on this important topic.
