Laparoscopic Right Hemicolectomy for Inflammatory Bowel Disease: Is Intracorporeal Anastomosis Feasible? A Retrospective Cohort Comparison Study.

Inflammatory bowel disease (IBD) affects all ages and backgrounds, and many individuals require surgical intervention during their disease course. The adoption of laparoscopic techniques in this patient population has been slow, including intracorporeal anastomosis (ICA). The aim of our study was to determine if ICA was feasible and safe in patients with IBD undergoing laparoscopic right hemicolectomy (LRHC).

Extent of Lymph Node Harvest: A Retrospective Cohort Comparison of Intracorporeal Versus Extracorporeal Anastomosis in Right Hemicolectomy.

Minimally invasive surgery has been demonstrated to have clear advantages in colon cancer management, with a decrease in the morbidity and mortality associated with surgery. With the introduction of intracorporeal anastomosis (ICA), the entire mesenteric dissection and division is performed under vision laparoscopically and may lead to superior lymph node harvest. The aim of our study is to evaluate lymph node harvest in patients undergoing totally laparoscopic right hemicolectomy with ICA compared to laparoscopic-assisted right hemicolectomy with extracorporeal anastomosis (ECA).

Laparoscopic right colectomies with intracorporeal compared to extracorporeal anastomotic techniques are associated with reduced post-operative incisional hernias.

Background: Owing to important differences in surgical technique, laparoscopic right colectomy with intracorporeal (ICA) compared to extracorporeal (ECA) anastomotic technique may result in improved patient outcomes. We aimed to compare both techniques according to incisional hernias and other pertinent perioperative characteristics, post-operative complications, and oncologic quality markers.

Methods: All adult patients undergoing laparoscopic right colectomies between 2015 and 2020 at a single institution were included.

Epilepsy Risk Following Bariatric Surgery for Weight Loss.

Background And Objectives: A previous study reported finding that epilepsy risk is elevated after bariatric surgery for weight loss; however, this association has not been adequately explored. Our objectives were to (1) estimate the risk of epilepsy after bariatric surgery for weight loss relative to a nonsurgical cohort of patients with an obesity diagnosis and (2) identify epilepsy risk factors among bariatric surgery recipients.

Methods: We conducted a population-based retrospective cohort study using linked health administrative databases in Ontario, Canada.

However, the economic impact of this intervention has not been investigated. This study is a cost analysis of the routine use of ICG-FA in colorectal surgery from the hospital payer perspective.

Cross-border healthcare: A review and applicability to North America during COVID-19.

Cross-border healthcare is an international agreement for the provision of out of country healthcare for citizens of partnered countries. The European Union (EU) has established itself as a world leader in cross-border healthcare. During the Coronavirus disease of 2019 (COVID-19) pandemic, the EU used this system to maximize utilization of resources.

Preoperative malnutrition in patients with colorectal cancer.

Preoperative malnutrition in patients with colorectal cancer is associated with several postoperative consequences and poorer prognosis. Currently, there is a lack of a universal screening tool to assess nutritional status, and intervention to treat preoperative malnutrition is often neglected. This review summarizes and compares preoperative screening and interventional tools to help providers optimize malnourished patients with colorectal cancer for surgery.

Risk factors for abdominal reoperations in bariatric patients.

Background: With a growing bariatric population, a better understanding of the patient and health provider-related factors associated with later reoperations could help providers enhance follow-up and develop reliable benchmarking targets.

Objectives: To investigate the patient and provider-related risk factors associated with abdominal reoperations in bariatric patients.

Setting: This is a cohort study using data from a large clinical registry of Ontario bariatric patients between 2010 and 2016.

Video Context Improves Performance in Identifying Operative Planes on Static Surgical Images.

Background: Correct identification of the surgical tissue planes of dissection is paramount at the operating room, and the needed skills seem to be improved with realistic dynamic models rather than mere still images. The objective is to assess the role of adding video prequels to still images taken from operations on the precision and accuracy of tissue plane identification using a validated simulation model, considering various levels of surgeons' experience.

Methods: A prospective observational study was conducted involving 15 surgeons distributed to three equal groups, including a consultant group [C], a senior group [S], and a junior group [J].

Colonic displacement as a marker of endoscopic skill: development of a novel tool for endoscopy training.

Background: Colonoscopy is a technically challenging procedure. The colonoscope is prone to forming loops in the colon, which can lead patient discomfort and even perforation. We hypothesized that expert endoscopists use techniques to avoid loop formation, identify and straighten loops earlier, and thus exert less force.

Safety of Same-day Discharge in High-risk Patients Undergoing Ambulatory General Surgery.

Background: Same-day surgery is an increasingly utilized and cost-effective strategy to manage common surgical conditions. However, many institutions limit ambulatory surgical services to only healthy individuals. There is also a paucity of data on the safety of same-day discharge among high-risk patients.

Access to bariatric surgery among older patients in a publicly funded regionalized care system.

Background: Bariatric surgery in older patients is safe and effective. Current guidelines do not endorse age limits for surgery; however, older patients may encounter difficulties with access given perceived risks. This study compares the adjusted probability of failing to receive bariatric surgery between older (≥ 60 years) and younger (< 60 years) patients referred to a publicly funded program.

Operating during COVID-19: Is there a risk of viral transmission from surgical smoke during surgery?

The World Health Organization declared a pandemic when coronavirus disease 2019 (COVID-19) started to sweep the globe. Growing concerns for the safety of health care workers was raised when up to 80% of people with COVID-19 showed mild or no symptoms at all. Some surgical procedures will be inevitable during the pandemic, and proper safety measures must be in place to avoid transmission risks.

Correlation of surgical trainee performance on laparoscopic versus endoscopic simulation.

Background: Both laparoscopy and endoscopy are image-based procedures, which are less intuitive than traditional open surgery and require extensive training to reach adequate proficiency. Currently, there is lack of understanding as to how the skills in one image-based procedure translate to another, such as endoscopy to laparoscopy and vice versa. The aim of our study was to explore the relationship between endoscopic and laparoscopic skills using a Fundamentals of Laparoscopic Surgery (FLS) trainer, a traditional virtual reality endoscopic trainer and a "desk-top" endoscopic physical simulator.

Canadian consensus statement: enhanced recovery after surgery in bariatric surgery.

Background: In Canada, bariatric surgery continues to remain the most effective treatment for severe obesity and its comorbidities. As the number of bariatric surgeries continues to grow, the need for consensus guidelines for optimal perioperative care is imperative. In colorectal surgery, enhanced recovery after surgery (ERAS) protocols were created for this purpose.

Mental health quality of life after bariatric surgery: A systematic review and meta-analysis of randomized clinical trials.

Recent literature has raised concerns regarding the risk of adverse psychiatric events among bariatric surgery patients. However, the relationship between weight loss therapy and psychiatric outcomes is confounded by baseline psychosocial characteristics in observational studies. To understand the impact of bariatric surgery on the risk of adverse mental health outcomes, we conducted a systematic review and meta-analysis of randomized controlled trials that compared surgical and non-surgical treatments and assessed mental health quality of life (QoL).
