Impact of the Covid-19 pandemic on rates of emergency department utilization and hospital admission due to general surgery conditions.

Background: Recent literature reports a decrease in healthcare-seeking behaviours by adults during the Covid-19 pandemic. Given that emergency general surgery (GS) conditions are often associated with high morbidity and mortality if left untreated, the objective of this study was to describe and quantify the impact of the Covid-19 pandemic on rates of emergency department (ED) utilization and hospital admission due to GS conditions.

Methods: This cohort study involved the analysis of an institutional database and retrospective chart review.

Patients' experiences of telenursing follow-up care after bariatric surgery.

Aim: To explore the postsurgical management experiences of bariatric patients after receiving telenursing follow-up care, using a telemonitoring platform for approximately 1 month.

Background: Obesity prevalence rates among adult Canadians are increasing, and as such the number of bariatric surgeries. Adapting to life following bariatric surgery is challenging, and patients are often experiencing difficulties to adhere to the postsurgical behavioural recommendations.

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.

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.

Development and Validation of a Clinical Risk Score for Intensive Care Resource Utilization After Colon Cancer Surgery: a Practical Guide to the Selection of Patients During COVID-19.

Background: The purpose of this study was to develop and validate a prediction model and clinical risk score for Intensive Care Resource Utilization after colon cancer surgery.

Methods: Adult (≥ 18 years old) patients from the 2012 to 2018 ACS-NSQIP colectomy-targeted database who underwent elective colon cancer surgery were identified. A prediction model for 30-day postoperative Intensive Care Resource Utilization was developed and transformed into a clinical risk score based on the regression coefficients.

Setting: University Hospital, Canada.

Laparoscopic Wedge Resection of Gastrojejunostomy for Weight Recidivism after Gastric Bypass.

Background: Weight recidivism after Roux-en-Y gastric bypass (RYGB) is a common problem. Often, this weight loss failure or regain may be due to a wide gastrojejunostomy (GJ). We evaluated the feasibility and safety of a novel approach of laparoscopic wedge resection of gastrojejunostomy (LWGJ) for a wide stoma after RYGB associated with weight recidivism.

Assessing the Effect of Preoperative Nutrition on Upper Body Function in Elderly Patients Undergoing Elective Abdominal Surgery.

Background: Malnutrition among elderly surgical patients has been associated with poor postoperative outcomes and reduced functional status. Although previous studies have shown that nutrition contributes to patient outcomes, its long-term impact on functional status requires better characterization. This study examines the effect of nutrition on postoperative upper body function over time in elderly patients undergoing elective surgery.

Laparoscopic Transgastric Resection of a Gastric Submucosal Tumor near Esophagogastric Junction with Concomitant Sleeve Gastrectomy: a Video Case Report.

Background: Over the past two decades, there has been a significant rise in bariatric surgery. As a consequence, the prevalence of obese patients with a combined gastric pathology such as a submucosal tumor (SMT) requiring excision at the same time as bariatric surgery is higher but the management remains controversial. We report the safety and effectiveness of a simultaneous laparoscopic transgastric resection of a large gastric SMT near the esophagogastric junction (EGJ) with sleeve gastrectomy (SG).

The impact of postoperative complications on the recovery of elderly surgical patients.

Background: While the negative impact of postoperative complications on hospital costs, survival, and cancer recurrence is well known, few studies have quantified the impact of postoperative complications on patient-centered outcomes such as functional status. The objective of this study was to estimate the impact of postoperative complications on recovery of functional status after elective abdominal surgery in elderly patients.

Methods: Elderly patients (70 years and older) undergoing elective abdominal surgery, with a planned length of stay >1 day, were prospectively enrolled between July 2012 and December 2014.

Simulation-based training improves the operative performance of totally extraperitoneal (TEP) laparoscopic inguinal hernia repair: a prospective randomized controlled trial.

Background: Laparoscopic surgery has an important role to play in the care of patients with inguinal hernias, but the procedure is difficult to learn. This study aimed to assess whether training to proficiency using a novel laparoscopic inguinal hernia repair (LIHR) simulation curriculum improved operating room (OR) performance.

Methods: For this study, 17 surgical residents [postgraduate years (PGYs) 2-5] participated in a didactic LIHR course and then were randomized to a training (T) or a control (C, standard residency) group.
