Robotic Curriculum Enhances Minimally Invasive General Surgery Residents' Education.

OBJECTIVE: Resident education is evolving as more cases move from open to minimally invasive. Many programs struggle to incorporate minimally invasive surgery education due to increased operative time and higher cost when residents participate. The aim of this paper is to examine if the implementation of a robotics curriculum enhances minimally invasive surgical training. DESIGN: A retrospective review of all ventral and inguinal hernia cases performed from March 2013 to November 2017 was conducted to determine operative technique utilized (open, laparoscopic, or robotic) and resident involvement. The study cohorts surrounded the introduction of a robotic curriculum in July 2014, and the time frames examined were labeled as Before-robotic, After-robotic, and re-visited examination was done labeled Long-term. SETTING: The study was performed at a large quaternary care referral center. PARTICIPANTS: The participants were all patients who underwent ventral and inguinal hernia repairs on the general surgery, transplant, or colorectal service. RESULTS: Before-robotic had 739 hernia cases performed: 642 (87%) open, 93 (13%) laparoscopic, and 4 (0.5%) robotic. After-robotic had 682 hernia cases performed: 529 (78%) open, 54 (8%) laparoscopic, and 99 (15%) robotic. Long-term had 792 hernia cases performed: 603 (76%) open, 25 (3%) laparoscopic, and 164 (21%) robotic. The general trend was towards an institutional decrease in open cases and an increase in robotic hernia cases. Resident participation in the robotics cases across all levels increased after the implementation of the robotic curriculum. CONCLUSIONS: Implementation of a robotic curriculum can enhance minimally invasive surgical training experience for general surgery resident education.

Age and Its Impact on Outcomes with Intra-Abdominal Infection.

BACKGROUND: Age has been shown to play a significant role in the etiology of complicated intra-abdominal infections (cIAIs), but the correlation between age and outcomes after therapy was not investigated in the Study to Optimize Peritoneal Infection Therapy (STOP-IT) trial. PATIENTS AND METHODS: Data were obtained by post hoc analysis of the STOP-IT trial database. Patients were stratified by age <65 or ≥65 years. Primary outcomes were surgical site infection (SSI), recurrent IAI (recIAI), and death. Multivariable analysis was performed to identify independent predictors of outcomes. RESULTS: There were 398 subjects <65 and 120 ≥ 65 years. Overall baseline characteristics of the two groups were similar. The site of infection was similar between groups except: Colon or rectum (48.3% vs. 29.9%, p = 0.0002) and biliary tree (16.7% vs. 9.1%, p = 0.02), which were more common in the older group, whereas small intestine (6.7% vs. 16.3%, p = 0.008) and appendix (4.2% vs.17.1%, p = 0.0004) were more common in the younger group. Among the primary outcomes, only death was significantly different between the age groups and was more prevalent in the ≥65 years group (4 [3.3%] vs. 1 [0.3%], p = 0.01). Surgical site infection (9.2% vs. 7.3%, p = 0.50), recIAI (15.8% vs. 14.4%, p = 0.69), and a composite outcome (26.7% vs. 20.4%, p = 0.14) were statistically similar between the age groups, and this remained true when controlling for other co-variables. Multivariable analyses did not reveal age as an independent predictor of the composite or individual outcomes. CONCLUSION: Patients with a more advanced age demonstrated variable sources of infection relative to the younger cohort, yet received similar treatments. Patient age was not an independent predictor of the undesired cIAI outcomes. These findings suggest that advanced age itself does not play a significant role in predicting these adverse outcomes for cIAIs and does not necessitate an altered treatment tactic.
