Neorectal prolapse is a rare occurrence following minimally invasive sphincter-saving surgical procedures performed for rectal cancer. It appears to be more frequent in patients who undergo MIS procedures and in women.

Up to 80% of the rectal injuries reported in US trauma centers occur secondary to firearm injuries. Rectal gunshot wounds are associated with significant morbidity and mortality. Diverse surgical approaches and techniques have been described; however, controversy persists regarding the best management for these complex injuries. Nowadays, no single approach has proven to provide optimal results when dealing with these injuries. We present a case of a young male that suffered a combined (intra-extraperitoneal) gun shot gun to the rectus and the use of a transanal platform to repair it.

HighlightsAccess to the excluded stomach in patients who have undergone a laparoscopic Roux-en-Y gastric bypass for evaluation and/or management remains a clinical concern.In order to facilitate the entrance to the gastric remnant, a silastic marker is left in place during the Fobi-Pouch operation.We report the first case of a patient presenting with an eroded silastic marker in the excluded stomach after a Fobi-Pouch operation.

72 Background: Online prediction tools for cancer risk can inform individuals about their risk and potentially encourage adoption of risk-modifying health behavior. The Colorectal Cancer Risk Assessment Tool (CCRAT) is an interactive tool developed by the National Cancer Institute for estimating colorectal cancer (CRC) risk for individuals between the ages of 45 and 85 without high risk predisposing conditions. Given the rising incidence of CRC among young adults under age 50, we aimed to investigate the performance of CCRAT in estimating their CRC risk. Methods: An institutional protocol prospectively enrolled 563 patients newly diagnosed with non-hereditary CRC and administered a health behavior questionnaire at baseline. Self-reported demographics, diet and physical activity, medication use, and family history were extracted and entered into the CCRAT ( https://ccrisktool.cancer.gov/calculator.html ) to calculate their predicted 5-year and lifetime CRC risks. Health behaviors and the predicted CRC risks in reference to the population average were compared among three groups: youngest- (aged 18-44, N = 276, 49%), young- (aged 45-50, N = 178, 32%), and older-onset (aged > 50, N = 109; 19%). Results: The patient groups did not significantly differ in gender or in family history of CRC, but the youngest group had significantly more non-White patients (27, 22, vs. 19%; p = 0.008) and distal tumors (80, 76 and 65%; p = 0.05). The youngest and young groups had a higher prevalence of morbid obesity (18 and 15% vs. 12%; p = 0.002) and active smokers (6 and 8% vs. 3%; p = 0.005). There were no significant differences in vegetable intake, moderate exercise, NSAID use, or female hormone use. The 5-year CRC risk was correctly predicted as “higher than average population” for a significantly smaller proportion of the youngest (42%) and young (45%) patients, when compared to their older counterpart (71%; p < 0.001). Similarly, the tool communicated “higher than average” lifetime risk for CRC in only 56 and 60% of the youngest and young patients, but 72% of the older ones (p = 0.021). Conclusions: The existing risk prediction tool inadequately communicated CRC risk for adults younger than 50 years of age. Risk factors underlying young-onset CRC likely differ from and extend beyond those as currently assessed. New tools capturing age-specific risk factors are needed to accurately communicate individualized risk and potentially motivate risk-modifying lifestyles.

Background Transanal minimally invasive surgery (TAMIS) is a surgical technique used for the excision of rectal neoplasia that gained popularity during the last decade.Due to the technical difficulty (non-articulated instruments, reduced workspace) and the long learning curve associated with this technique, the use of robotic platforms to improve resection results has been suggested and reported, at the same time that the learning curve decreases and the procedure is facilitated Materials and Methods From March 2017 to December 2019, all patients with rectal lesions eligible for TAMIS were offered the possibility to receive a robotic TAMIS (R-TAMIS). We used a transanal GelPoint Path (Applied Medical Inc., Santa Margarita, CA, USA) in the anal canal to be able to do the Da Vinci Si (Intuitive Surgical, Sunnyvale, CA, USA) robotic platform docking, which we used to perform the excision of the rectal lesion as well as the resection site defect. Results Five patients between 34 and 79 years of age underwent R-TAMIS. The mean distance to the anal verge was 8.8 cm. There were no conversions. The mean surgery time was 85 minutes, and the mean docking time was 6.6 minutes. Conclusions Robotic TAMIS is a feasible alternative to TAMIS, with a faster learning curve for experienced surgeons in transanal surgery and better ergonomics. Further studies are needed to assess the cost-benefit relationship.
