Current status of robotic surgery in colorectal residency training programs.

BACKGROUND: Robotic surgery (RS) has been increasingly incorporated into colorectal surgery (CRS) training. The degree to which RS has been integrated into CRS residency training is not well described. METHODS: A web-based survey was sent to all 2019 accredited CRS residency programs within the United States and Canada. Program directors (PDs) were queried on how robotic surgery had been integrated into their program, specifics on RS curriculum and opinions on RS training during general surgery residency. We compared survey responses by program type (university-based, university-affiliated programs, or independent programs) and by geographic region. In addition, a chi-square test was used to evaluate differences in survey responses with respect to robotic curriculum components. RESULTS: Of 66 programs, 42 (64%) responded to the survey. Of the responding programs, 35 (83%) were university-based or university-affiliated, while 7 (17%) were independent. Most programs were in the Midwest (33%). Forty-one (98%) reported having a surgical robot in use at their institution, with 95% reporting active participation of CRS residents in RS. While 74% of programs have a formal RS training curriculum for CRS residents, there was considerable variability in the curriculum elements employed by each institution, and the differences in proportions of these elements were significant (χ2 99.8, p < 0.001). The median operative approach to abdominopelvic cases was estimated to be 33% robotic, 40% laparoscopic and 20% open. There were no significant differences in the survey responses between university/university-affiliated and independent programs (p > 0.05) or among the different regions (p > 0.05). CONCLUSIONS: This study demonstrated that almost all CRS residencies have integrated RS and have trainees operating at the robotic console. Most programs have a robotics curriculum and there are expanding indications for RS within CRS. This expansion calls for discussion on implementation of training standards such as curricular requisites, baseline competency assessments, and definitions of minimum case requirements to ensure adequate training.

Association of Geriatric Events With Perioperative Outcomes After Elective Inpatient Surgery.

BACKGROUND: Older adults undergoing surgery are at risk for geriatric events (GEs: delirium, dehydration, falls or fractures, failure to thrive, and pressure ulcers). The prevalence and association of GEs with clinical outcomes after elective surgery is unclear. MATERIALS AND METHODS: Using the 2013-2014 National Inpatient Sample, we analyzed hospital admissions for the five most common elective procedures (total knee arthroplasty, right hemicolectomy, carotid endarterectomy, aortic valve replacement, and radical prostatectomy) in older adults (age ≥ 65). Our primary variable of interest was presence of any GE. Logistic regression estimated the association of GEs with (1) age group and (2) perioperative outcomes (mortality, postoperative complications, prolonged length of stay, and discharge to skilled nursing facility). RESULTS: Of 1,255,120 admissions, 66.5% were aged ≥65. The overall rate of any GE was 2.4% and increased with age (55-64 y: 1.5%; 65-74: 2.2%; ≥75: 4.1%; P < 0.001). After adjustment, the probability of any GE increased with age (P < 0.001). Rates of GEs varied by procedure (P < 0.001). In comparison with admissions with no GEs, one or more GE was associated with higher probability of worse outcomes including mortality, postoperative complications, prolonged length of stay, and discharge to skilled nursing facility (all P < 0.001). In addition, there was a dose-dependent relationship between GEs and these poor perioperative outcomes. CONCLUSIONS: GEs are strongly associated with poor perioperative outcomes. Efforts should focus on mutable factors responsible for GEs to optimize surgical care for older adults.

Perioperative Pain Management Issues Unique to Older Adults Undergoing Surgery: A Narrative Review.

INTRODUCTION: The older population is growing and with this growth there is a parallel rise in the operations performed on this vulnerable group. The perioperative pain management strategy for older adults is unique and requires a team-based approach for provision of high-quality surgical care. METHODS: Literature search was performed using PubMed in addition to review of relevant protocols and guidelines from geriatric, surgical, and anesthesia societies. Systematic reviews and meta-analyses, randomized trials, observational studies, and society guidelines were summarized in this review. MANAGEMENT: The optimal approach to a pain management strategy for older adults undergoing surgery involves addressing all phases of perioperative care. For example, preoperative assessment of a patient's cognitive function and presence of chronic pain may impact the pain management plan. Consideration should be also given to intraoperative strategies to improve pain control and minimize both the dose and side effects from opioids (e.g. regional anesthetic techniques). Postoperative pain control (e.g. under or over treatment of pain) may impact the development of elderly-specific complications such as postoperative delirium and functional decline. Finally, pain management does not stop after the older adult patient leaves the hospital. Both discharge planning and post-operative clinic follow-up provide important opportunities for collaboration and intervention. CONCLUSIONS: An opioid-sparing pain management strategy for older adults can be accomplished with a comprehensive and collaborative interdisciplinary strategy addressing all phases of perioperative care.

A multi-institutional study assessing general surgery faculty teaching evaluations.

BACKGROUND: Resident evaluation of faculty teaching is an important metric in general surgery training, however considerable variability in faculty teaching evaluation (FE) instruments exists. STUDY DESIGN: Twenty-two general surgery programs provided their FE and program demographics. Three clinical education experts performed blinded assessment of FEs, assessing adherence 2018 ACGME common program standards and if the FE was meaningful. RESULTS: Number of questions per FE ranged from 1 to 29. The expert assessments demonstrated that no evaluation addressed all 5 ACGME standards. There were significant differences in the FEs effectiveness of assessing the 5 ACGME standards (p < 0.001), with teaching abilities and professionalism rated the highest and scholarly activities the lowest. CONCLUSION: There was wide variation between programs regarding FEs development and adhered to ACGME standards. Faculty evaluation tools consistently built around all suggested ACGME standards may allow for a more accurate and useful assessment of faculty teaching abilities to target professional development.

Diverting Loop Ileostomy for Clostridium Difficile Colitis: A Systematic Review and Meta-analysis.

Diverting loop ileostomy (DLI) with colonic lavage has been proposed as an alternative to total abdominal colectomy (TAC) for fulminant Clostridium difficile infection (CDI). Controversy exists regarding the mortality benefit and outcomes of this surgical approach. We conducted a MEDLINE database search for articles between 1999 and 2019 pertaining to DLI for the surgical treatment of CDI. Five articles met the inclusion criteria. Four studies were retrospective and one was a prospective matched cohort study. 3683 patients were included in the 5 studies; 733 patients (20%) underwent DLI, while 2950 patients (80%) underwent TAC. The only shared outcome measure across all 5 studies was mortality. The overall mortality rate for the entire cohort undergoing both procedures was 30.3%. There was no statistically significant difference in pooled mortality between DLI and TAC (OR: .73; 95% CI, .45-1.2; P = .22). Reporting of other postoperative outcomes was variable. Fulminant CDI remains a life-threatening condition with high mortality. Loop ileostomy may be a viable surgical alternative to total colectomy with similar mortality; however, further work is needed to determine specific patient characteristics that warrant routine use of DLI.

Trauma patients returning to the emergency department after discharge.

BACKGROUND: While readmission rates of trauma patients are well described, little has been reported on rates of re-presentation to the emergency department (ED) after discharge. This study aimed to determine rates and contributing factors of re-presentation of trauma patients to the ED. METHODS: One-year retrospective analysis of discharged adult trauma patients at a county-funded safety-net level one trauma center. RESULTS: Of 1416 trauma patients, 195 (13.8%) re-presented to the ED within 30 days. Of those that re-presented, 47 (24.1%) were re-admitted (3.3% overall). The most common reasons for re-presentation were pain control and wound complications. Patients with Medicare (AOR 2.6, 95% CI 1.3 to 5.2) or other government insurance (AOR 2.5, 95% CI 1.6 to 4.1) were more likely to re-present than patients with private insurance. CONCLUSION: A considerable number of trauma patients re-presented to the ED after discharge for reasons that did not require hospitalization. Discharge planning for certain vulnerable groups should emphasize wound care, pain control and scheduled follow-up to decrease the reliance on the ED.

Investigating Association Between Sex and Faculty Teaching Evaluation in General Surgery Residency Programs: A Multi-Institutional Study.

BACKGROUND: In specialties with gender imbalance, such as general surgery, women faculty frequently receive lower teaching evaluation scores compared with men, which can affect academic advancement. STUDY DESIGN: We collected 1 year of anonymous resident-derived faculty teaching evaluations from 21 general surgery programs, along with resident, faculty, and department leadership gender complement. A composite evaluation score was calculated for each faculty. After accounting for within-program correlations, we compared male and female scores using the cluster-adjusted t-test to describe the respective mean differences with a 95% CI. Programs were divided into quartiles based on percent female faculty, female residents, and combined total females to detect associations between female representation and faculty teaching evaluation scores. RESULTS: The 21 programs yielded 20,187 teaching evaluations of 1,177 faculty. Women comprised 28% of the faculty, 47% of residents, 43% of program directors, and 19% of department chairs. Overall, women faculty had significantly higher evaluation scores than men (90.6% vs 89.5%, p < 0.05). Female gender was associated with higher teaching evaluation scores compared with male faculty in the lowest quartiles for all combinations of women representation. CONCLUSIONS: This multi-institutional analysis of general surgical resident evaluations of faculty identified that female gender was associated with higher evaluation scores than men (although the difference was small). This unanticipated finding might reflect the slowly changing gender balance within general surgery and attitudes towards female faculty in a traditionally male-dominated field. Contrary to our hypothesis, female gender was associated with higher faculty evaluation scores at programs with fewer women faculty and fewer women residents.

Biomechanical Consequences of Anterior Femoral Notching in Cruciate-Retaining Versus Posterior-Stabilized Total Knee Arthroplasty.

Anterior femoral notching during total knee arthroplasty is a potential risk factor for periprosthetic supracondylar femur fracture. We conducted a study to determine if the design of the femoral implant changes the risk for periprosthetic supracondylar femur fractures after anterior cortical notching. An anterior cortical defect was created in 12 femoral polyurethane models. Six femora were instrumented with cruciate-retaining implants and 6 with posterior-stabilized implants. Each femur was loaded in external rotation along the anatomical axis. Notch depth and distance from anterior cortical notch to implant were recorded before loading, and fracture pattern was recorded after failure. There were no statistically significant differences in notch depth, distance from notch to implant, torsional stiffness, torque at failure, final torque, or fracture pattern between cruciate-retaining and posterior-stabilized femoral component designs. Periprosthetic fracture after anterior femoral notching is independent of the bone removed from the intercondylar notch. After notching, there likely is no significant difference in femoral strength in torsion between cruciate-retaining and posterior-stabilized designs.
