Title: Malignant Colorectal Polyp Pathology: Are We Getting Sufficient Information to Make Decisions?

Video Creator:  Gimon, Tamara I. M.D.1; Dykstra, Mark A. M.D., F.R.C.S.C.1; Chezar, Ksenia M.D.2; Buie, W. Donald M.D., M.Sc., F.R.C.S.C.1; MacLean, Anthony M.D., F.R.C.S.C.1  

Description: There is a high rate of incomplete reporting of core and optional elements for malignant colorectal polyp pathology reports in Alberta. Several variables used by colorectal surgeons for decision making, such as tumor budding and depth of submucosal invasion, are not considered core elements and are infrequently reported. A pathology review by a second pathologist often results in a change in risk stratification.




Title: Evaluation of Rectal Cancer Circumferential Resection Margin Using Faster Region-Based Convolutional Neural Network in High-Resolution Magnetic Resonance Images

Video Creator:  Wang, Dongsheng Ph.D.1; Xu, Jihua M.S.1; Zhang, Zhengdong M.S.2; Li, Shuai Ph.D.2; Zhang, Xianxiang Ph.D.1; Zhou, Yunpeng M.S.1,3; Zhang, Xunying M.S.1; Lu, Yun Ph.D.1,3  

Description:  In high-resolution MRI images of rectal cancer before treatment, the application of faster region-based convolutional neural network to segment the positive circumferential resection margin has high accuracy and feasibility.  




Title: Extent of Pedigree Required to Screen for and Diagnose Hereditary Nonpolyposis Colorectal Cancer: Comparison of Simplified and Extended Pedigrees

B.S.1; Bang, Sukyung B.S.1; Kim, Myung Jo M.D.1; Oh, Heung-Kwon M.D.1; Kang, Sung-Bum M.D., Ph.D.1; Kang, Sung Il M.D.2; Park, Ji Won M.D., Ph.D.3; Ryoo, Seung-Bum M.D., Ph.D.3; Jeong, Seung-Yong M.D., Ph.D.3; Park, Kyu Joo M.D., Ph.D.3 

Description: A simplified pedigree is acceptable for selecting candidates to screen for hereditary colorectal cancer, whereas an extended pedigree is still required for a more precise diagnosis of Lynch syndrome, especially in younger patients.



Title: Does Smoking Cessation Reduce Surgical Recurrence After Primary Ileocolic Resection for Crohn’s Disease?Video Creator:  Bolckmans, Roel M.D.1; Kalman, Thordis M.D.2; Singh, Sandeep M.D.1; Ratnatunga, Keshara C. M.D.1; Myrelid, Pär M.D., Ph.D.2; Travis, Simon M.D., Ph.D.3; George, Bruce D. M.D.1  

Description: Smoking cessation after primary ileocolic resection for Crohn’s disease may significantly reduce long-term risk of surgical recurrence and is associated with less use of maintenance therapy.



Title: Readmission for Treatment Failure After Nonoperative Management of Acute Diverticulitis: A Nationwide Readmissions Database Analysis

Video Creator:  Al-Masrouri, Safiya M.D., M.Sc.1; Garfinkle, Richard M.D., M.Sc.1; Al-Rashid, Faisal M.D.1; Zhao, Kaiqiong Ph.D.2; Morin, Nancy M.D.1; Ghitulescu, Gabriela A. M.D.1; Vasilevsky, Carol-Ann M.D.1; Boutros, Marylise M.D.1  

Description:  The incidence of readmission for treatment failure after an episode of diverticulitis managed nonoperatively is 6.6%, and an index episode of complicated diverticulitis is the strongest risk factor for treatment failure.  



Title: The Association of Enhanced Recovery Pathway and Acute Kidney Injury in Patients Undergoing Colorectal Surgery

Video Creator:  Wiener, Jameson G.D. B.S.; Goss, Lauren M.S.P.H.; Wahl, Tyler S. M.D., M.S.P.H.; Terry, Morgan A. B.S.; Burge, Kaitlin G. B.A.; Chu, Daniel I. M.D.; Richman, Joshua S. M.D., Ph.D.; Cannon, Jamie M.D.; Kennedy, Gregory D. M.D., Ph.D.; Morris, Melanie S. M.D.  

Description:  The implementation of an enhanced recovery after surgery protocol is independently associated with the development of postoperative acute kidney injury. 



Title: Pressurized Intraperitoneal Aerosol Chemotherapy, a Palliative Treatment Approach for Patients With Peritoneal Carcinomatosis: Description of Method and Systematic Review of Literature

Video Creator:  Winkler, Carl S. M.D.1; Sandhu, Jaspreet M.D.2; Pettke, Erica M.D.1; Merchea, Amit M.D.3; Fong, Yuman M.D.4; Kumara, H.M.C. Shantha Ph.D.5; Whelan, Richard L. M.D.5  

Description: Early clinical results are encouraging, but tumor-specific, prospective, randomized trials are needed to compare pressurized intraperitoneal aerosol chemotherapy to systemic chemotherapy. This method has yet to be introduced to the United States. It is another therapeutic option for patients with peritoneal metastases and will broaden the patient base for future clinical trials.
