Our study is one of the largest reviews of robotic colorectal surgery to date. We believe that our results further demonstrate the equivalence of robotic surgery to laparoscopic surgery in colorectal procedures. Future research should focus on surgeon-specific variables, such as comfort, ergonomics, distractibility, and ease of use, as other ways to potentially distinguish robotic from laparoscopic colorectal surgery.

Postprandial GLP-1 levels increase after RYGB, while fasting levels remain unchanged. Shorter Roux limb length is associated with greater increase in postprandial GLP-1, which may lead to better glycemic control in this population.

The use of drains in colorectal surgery has been a subject of debate for several decades. Prophylactic drainage of the peritoneal cavity has become less popular in recent years. This change is due to several studies demonstrating that intraperitoneal drains do not adequately drain the peritoneal cavity and do not prevent or contain anastomotic leaks. Percutaneous drain placement has become the standard of care for patients with intra-abdominal abscesses. Selected anastomotic leaks in the stable patient can also be managed with percutaneous drains. In this article, the authors review in detail the use of drains and the literature to support their use in our everyday practice.

Diagnosis of hereditary colorectal cancer syndromes requires clinical suspicion and knowledge of such syndromes. Lynch syndrome is the most common cause of hereditary colorectal cancer. Other less common causes include familial adenomatous polyposis (FAP), Peutz-Jeghers syndrome (PJS), juvenile polyposis syndrome, and others. There have been a growing number of clinical and molecular tools used to screen and test at risk individuals. Screening tools include diagnostic clinical criteria, family history, genetic prediction models, and tumor testing. Patients who are high risk based on screening should be referred for genetic testing.
