High incidence of potentially preventable emergency department visits after major elective colorectal surgery.

Introduction: Emergency department (ED) visits after surgery represent a significant cost burden on the healthcare system. Furthermore, many ED visits are related to issues of healthcare delivery services and may be avoidable. Few studies have assessed the reasons for ED visits after colorectal surgery.

The Effect of Preoperative Anemia and Perioperative Transfusion on Surgical Outcomes After Gastrectomy for Gastric Cancer.

Background: The aim of this study is to examine the interaction between preoperative anemia and perioperative transfusions with postoperative morbidity and mortality among patients undergoing gastrectomy for cancer.

Materials And Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2005 to 2016. Restricted cubic splines modeled the nonlinear relationship between preoperative hematocrit (Hct) and 30-day overall morbidity, sepsis, and mortality.

Endoscopic Submucosal Dissection for Upper Gastrointestinal Neoplasia-a North American Perspective.

Objectives: Organ-sparing endoscopic submucosal dissection (ESD) is an acceptable treatment strategy for superficial neoplastic lesions of the esophagus and stomach. The adoption of this technique has lagged in North America compared with Asia, and we sought to report on our experiences with ESD for upper GI neoplasia.

Methods: A prospectively entered database of all patients undergoing endoscopic resection of esophageal and gastric neoplasia at McGill University from 2009 to 2019 was queried for those who received ESD.

Patients' preferences for sphincter preservation versus abdominoperineal resection for low rectal cancer.

Background: Surgery for low rectal cancer can be associated with severe bowel dysfunction and impaired quality of life. It is important to determine how patients value the trade-off between anorectal dysfunction versus abdominoperineal resection. Therefore, the objective was to determine patients' preferences for treatment for low rectal cancer.

Meta-analysis of the Diagnostic Accuracy of C-Reactive Protein for Infectious Complications in Laparoscopic Versus Open Colorectal Surgery.

Introduction: C-reactive protein may predict anastomotic complications after colorectal surgery, but its predictive ability may differ between laparoscopic and open resection due to differences in stress response. Therefore, the objective of this study was to perform a systematic review and meta-analysis on the diagnostic characteristics of C-reactive protein to detect anastomotic leaks and infectious complications after laparoscopic and open colorectal surgery.

Methods: A systematic review was performed according to PRISMA.

Intracorporeal versus extracorporeal anastomosis for right colectomy does not affect gastrointestinal recovery within an enhanced recovery after surgery program.

Introduction: Delayed gastrointestinal (GI) recovery remains a significant morbidity after colorectal surgery. Intracorporeal anastomosis for right colectomy may hasten GI recovery. Therefore, the objective of this study was to determine the effect of intracorporeal versus extracorporeal anastomosis on GI recovery after elective laparoscopic right colectomy within an established ERAS program.

The relationship of two postoperative complication grading schemas with postoperative quality of life after elective colorectal surgery.

Introduction: Several grading schemes are available to assess surgical complications, but their relationship with patient-reported outcomes is not well understood. Therefore, our objective was to examine the effect of two complication grading schemas on health-related quality of life in colorectal surgery patients.

Methods: An analysis of adult patients undergoing elective colorectal surgery from 2005 to 2013 was performed.

Comparison of Dor and Nissen fundoplication after laparoscopic paraesophageal hernia repair.

Background: Fundoplication is performed routinely during laparoscopic repairs of a paraesophageal hernia, but the degree of fundoplication remains controversial. The purpose of this study is to assess postoperative dysphagia and reflux after a Dor versus a Nissen fundoplication in patients undergoing laparoscopic repair of giant paraesophageal hernias.

Methods: We performed a retrospective cohort study of all patients undergoing laparoscopic repair of giant paraesophageal hernias with Nissen or Dor fundoplication between January 2012 and December 2017 at a high-volume center, excluding revisional and emergency cases.

Examining the relationship between lymph node harvest and survival in patients undergoing colectomy for colon adenocarcinoma.

Background: Current standards for lymph node harvest in colorectal cancer surgery may be inadequate. Higher lymph node yield may improve survival, but the number of lymph nodes needed to optimize survival is unknown. The objective of this study was to examine the relationship between lymph node yield and overall survival in patients undergoing colectomy for nonmetastatic colon adenocarcinoma.

Impact of residual nodal involvement after complete tumor response in patients undergoing neoadjuvant (chemo)radiotherapy for rectal cancer.

Background: The management of patients with a complete clinical response after neoadjuvant therapy for rectal adenocarcinoma is controversial. Those who advocate for resection point out the inaccuracy of N-staging with current imaging modalities. The objective of this study is to determine the impact of residual nodal involvement after complete tumor regression after neoadjuvant (chemo)radiotherapy.

The Impact of Delays to Definitive Surgical Care on Survival in Colorectal Cancer Patients.

Introduction: Treatment delay may have detrimental effects on cancer outcomes. The impact of longer delays on colorectal cancer outcomes remains poorly described. The objective of this study was to determine the effect of delays to curative-intent surgical resection on survival in colorectal cancer patients.

Improved Disease-free Survival After Prehabilitation for Colorectal Cancer Surgery.

Objective: The objective of this study was to investigate the effect of prehabilitation on survival after colorectal cancer surgery.

Summary Of Background Data: Preoperative multimodal exercise and nutritional programs (prehabilitation) improve functional capacity and recovery following colorectal surgery. Exercise may also affect cancer outcomes by mediating the systemic inflammatory response.

Cost-Effectiveness of Extended Thromboprophylaxis in Patients Undergoing Colorectal Surgery from a Canadian Health Care System Perspective.

Background: There is increasing evidence to support extended thromboprophylaxis after colorectal surgery to minimize the incidence of postdischarge venous thromboembolic events. However, the absolute number of events is small, and extended thromboprophylaxis requires significant resources from the health care system.

Objective: This study aimed to determine the cost-effectiveness of extended thromboprophylaxis in patients undergoing colorectal surgery for malignancy or IBD.
