Clinical Utility of Laser Speckle Contrast Imaging and Real-Time Quantification of Bowel Perfusion in Minimally Invasive Left-Sided Colorectal Resections.

BACKGROUND: Left-sided colorectal surgery demonstrates high anastomotic leak rates, with tissue ischemia thought to influence outcomes. Indocyanine green is commonly used for perfusion assessment, but evidence remains mixed for whether it reduces colorectal anastomotic leaks. Laser speckle contrast imaging provides dye-free perfusion assessment in real-time through perfusion heat maps and quantification. OBJECTIVE: This study investigates the efficacy of advanced visualization (indocyanine green versus laser speckle contrast imaging), perfusion assessment, and utility of laser speckle perfusion quantification in determining ischemic margins. DESIGN: Prospective intervention group using advanced visualization with case-matched, retrospective control group. SETTINGS: Single academic medical center. PATIENTS: Forty adult patients undergoing elective, minimally invasive, left-sided colorectal surgery. INTERVENTIONS: Intraoperative perfusion assessment using white light imaging and advanced visualization at 3 time points: T1-proximal colon after devascularization, before transection, T2-proximal/distal colon before anastomosis, and T3-completed anastomosis. MAIN OUTCOME MEASURES: Intraoperative indication of ischemic line of demarcation before resection under each visualization method, surgical decision change using advanced visualization, post hoc laser speckle perfusion quantification of colorectal tissue, and 30-day postoperative outcomes. RESULTS: Advanced visualization changed surgical decision-making in 17.5% of cases. For cases in which surgeons changed a decision, the average discordance between the line of demarcation in white light imaging and advanced visualization was 3.7 cm, compared to 0.41 cm ( p = 0.01) for cases without decision changes. There was no statistical difference between the line of ischemic demarcation using laser speckle versus indocyanine green ( p = 0.16). Laser speckle quantified lower perfusion values for tissues beyond the line of ischemic demarcation while suggesting an additional 1 cm of perfused tissue beyond this line. One (2.5%) anastomotic leak occurred in the intervention group. LIMITATIONS: This study was not powered to detect differences in anastomotic leak rates. CONCLUSIONS: Advanced visualization using laser speckle and indocyanine green provides valuable perfusion information that impacts surgical decision-making in minimally invasive left-sided colorectal surgeries.

UTILIDAD CLNICA DE LAS IMGENES DE CONTRASTE MOTEADO CON LSER Y LA CUANTIFICACIN EN TIEMPO REAL DE LA PERFUSIN INTESTINAL EN RESECCIONES COLORRECTALES DEL LADO IZQUIERDO MNIMAMENTE INVASIVAS: ANTECEDENTES:La cirugía colorrectal del lado izquierdo demuestra altas tasas de fuga anastomótica, y se cree que la isquemia tisular influye en los resultados. El verde de indocianina se utiliza habitualmente para evaluar la perfusión, pero la evidencia sobre si reduce las fugas anastomóticas colorrectales sigue siendo contradictoria. Las imágenes de contraste moteado con láser proporcionan una evaluación de la perfusión sin colorantes en tiempo real a través de mapas de calor de perfusión y cuantificación.OBJETIVO:Este estudio investiga la eficacia de la evaluación de la perfusión mediante visualización avanzada (verde de indocianina versus imágenes de contraste moteado con láser) y la utilidad de la cuantificación de la perfusión con moteado láser para determinar los márgenes isquémicos.DISEÑO:Grupo de intervención prospectivo que utiliza visualización avanzada con un grupo de control retrospectivo de casos emparejados.LUGARES:Centro médico académico único.PACIENTES:Cuarenta pacientes adultos sometidos a cirugía colorrectal electiva, mínimamente invasiva, del lado izquierdo.INTERVENCIONES:Evaluación de la perfusión intraoperatoria mediante imágenes con luz blanca y visualización avanzada en tres puntos temporales: T1-colon proximal después de la devascularización, antes de la transección; T2-colon proximal/distal antes de la anastomosis; y T3-anastomosis completa.PRINCIPALES MEDIDAS DE VALORACIÓN:Indicación intraoperatoria de la línea de demarcación isquémica antes de la resección bajo cada método de visualización, cambio de decisión quirúrgica mediante visualización avanzada, cuantificación post-hoc de la perfusión con láser moteado del tejido colorrectal y resultados posoperatorios a los 30 días.RESULTADOS:La visualización avanzada cambió la toma de decisiones quirúrgicas en el 17,5% de los casos. Para los casos en los que los cirujanos cambiaron una decisión, la discordancia promedio entre la línea de demarcación en las imágenes con luz blanca y la visualización avanzada fue de 3,7 cm, en comparación con 0,41 cm (p = 0,01) para los casos sin cambios de decisión. No hubo diferencias estadísticas entre la línea de demarcación isquémica utilizando láser moteado versus verde de indocianina (p = 0,16). El moteado con láser cuantificó valores de perfusión más bajos para los tejidos más allá de la línea de demarcación isquémica y al mismo tiempo sugirió 1 cm adicional de tejido perfundido más allá de esta línea. Se produjo una fuga anastomótica (2,5%) en el grupo de intervención.LIMITACIONES:Este estudio no tuvo el poder estadístico suficiente para detectar diferencias en las tasas de fuga anastomótica.CONCLUSIONES:La visualización avanzada utilizando moteado láser y verde de indocianina proporciona información valiosa sobre la perfusión que impacta la toma de decisiones quirúrgicas en cirugías colorrectales mínimamente invasivas del lado izquierdo.

Measuring Chief Resident Skill and Entrustment Progression in An Operative Coaching Program: Four Years' Experience.

OBJECTIVE: Operative coaching (OC) may facilitate improvement of surgery residents' competencies by optimizing learning and teaching. We investigated how residents' operative skills and prospective entrustment (PE) progress throughout the chief year in our OC program, how OC is perceived by participants, and how OC may facilitate learning and teaching. DESIGN, SETTING, AND PARTICIPANTS: This is a mixed-methods study conducted within the Ohio State University Wexner Medical Center General Surgery residency. Validated performance evaluations with procedural-specific skill, general skill (GS), step-specific guidance required (SSG) (an autonomy measure), and PE measures completed by chiefs, faculty coaches, and attending surgeons from 7/2018 to 6/2022 were reviewed. We also interviewed OC participants to understand their experience. Descriptive statistical and qualitative content analysis were applied. RESULTS: 441 evaluations from 147 OC cases completed by 22 chiefs, 5 faculty coaches, and 24 attendings were included. Overall, resident GS (p = 0.036), SSG (p = 0.023), and PE (p = 0.002) significantly improved throughout the year. PE significantly correlated (all p < 0.0001) with SSG (r = 0.73), followed by procedural-specific skill (r = 0.59), then GS (r = 0.57). On average, chiefs underestimated their surgical skills while attendings overestimated autonomy they permitted to residents. Chiefs, coaches, and attendings reached consensus on chiefs' PE upon graduation. Five graduated chiefs and 5 attendings were interviewed. Chiefs described OC as effective in improving their self-regulated learning and particularly valued 3 OC elements: neutral authentic feedback, third-party real-time observation, and actionable feedback. Attendings noted OC promoted their engagement in skills assessment and teaching. CONCLUSIONS: Our findings suggest chief residents' skills, autonomy, and PE progress steadily along their OC journey. Despite differences in residents', coaches', and attendings' perceptions of skill, measures of autonomy reliably correlate with entrustment. OC promotes resident learning, faculty teaching, and assessment of resident skills, autonomy, and PE in the OR.

The SAGES MASTERS program presents: the top 10 seminal articles for laparoscopic left and sigmoid colectomy pathway for uncomplicated disease.

BACKGROUND: As one of the 8 Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program clinical pathways, the Colorectal Pathway aims to deliver educational content for the general surgeon organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure. In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic left/sigmoid colectomy for uncomplicated disease. METHODS: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic left and sigmoid colectomy were identified, reviewed, and ranked by members of the SAGES Colorectal Task Force. Additional articles not identified in the literature search were included if deemed impactful by expert consensus. The top 10 ranked articles were then summarized, including their findings, strengths and limitations with emphasis on relevance and impact in the field. RESULTS: The top 10 articles selected focus on variations in minimally invasive surgical techniques, video demonstrations, stratified approaches for benign and malignant disease as well as assessments of the learning curve. CONCLUSIONS: The selected top 10 seminal articles for laparoscopic left and sigmoid colectomy in uncomplicated disease are considered by the SAGES colorectal task force to be fundamental to the knowledge base of minimally invasive surgeons as they progress to mastery in these procedures.

A Multicenter Analysis of the Early Impact of COVID-19 on Junior Resident Operative Case Volume.

INTRODUCTION: Institutions have reported decreases in operative volume due to COVID-19. Junior residents have fewer opportunities for operative experience and COVID-19 further jeopardizes their operative exposure. This study quantifies the impact of the COVID-19 pandemic on resident operative exposure using resident case logs focusing on junior residents and categorizes the response of surgical residency programs to the COVID-19 pandemic. MATERIALS AND METHODS: A retrospective multicenter cohort study was conducted; 276,481 case logs were collected from 407 general surgery residents of 18 participating institutions, spanning 2016-2020. Characteristics of each institution and program changes in response to COVID-19 were collected via surveys. RESULTS: Senior residents performed 117 more cases than junior residents each year (P < 0.001). Prior to the pandemic, senior resident case volume increased each year (38 per year, 95% confidence interval 2.9-74.9) while junior resident case volume remained stagnant (95% confidence interval 13.7-22.0). Early in the COVID-19 pandemic, junior residents reported on average 11% fewer cases when compared to the three prior academic years (P = 0.001). The largest decreases in cases were those with higher resident autonomy (Surgeon Jr, P = 0.03). The greatest impact of COVID-19 on junior resident case volume was in community-based medical centers (246 prepandemic versus 216 during pandemic, P = 0.009) and institutions which reached Stage 3 Program Pandemic Status (P = 0.01). CONCLUSIONS: Residents reported a significant decrease in operative volume during the 2019 academic year, disproportionately impacting junior residents. The long-term consequences of COVID-19 on junior surgical trainee competence and ability to reach cases requirements are yet unknown but are unlikely to be negligible.

All Politics Are Local: A Single Institution Investigation of the Educational Impact of Residents and Fellows Working Together.

BACKGROUND: Most general surgery residents pursue fellowship; there is limited understanding of the impact residents and fellows have on each other's education. The goal of this exploratory survey was to identify these impacts. MATERIALS AND METHODS: Surgical residents and fellows at a single academic institution were surveyed regarding areas (OR assignments, the educational focus of the team, roles and responsibilities on the team, interpersonal communication, call, "other") hypothesized to be impacted by other learners. Impact was defined as "something that persistently affects the clinical learning environment and a trainee's education or ability to perform their job". Narrative responses were reviewed until dominant themes were identified. RESULTS: Twenty-three residents (23/45, 51%) and 12 fellows (12/21, 57%) responded. Responses were well distributed among resident year (PGY-1:17% [4/23], PGY-2, 35% [8/23], PGY-3 26% [6/23], PGY-4 9% [2/23%], PGY-5 13% [3/23]). Most residents reported OR assignment (14/23, 61%) as the area of primary impact, fellows broadly reported organizational categories (Roles and responsibilities 33%, educational focus 16%, interpersonal communication 16%). Senior residents reported missing out on operations to fellows while junior residents reported positive impacts of operating directly with fellows. Residents of all levels reported that fellows positively contributed to their education. Fellows, senior residents, and junior residents reported positive experiences when residents and fellows operated together as primary surgeon and assistant. CONCLUSIONS: Residents and fellows impact one another's education both positively and negatively. Case allocation concerns senior residents, operating together may alleviate this, providing a positive experience for all trainees. Defining a unique educational role for fellows and delineating team expectations may maximize the positive impacts in this relationship.

The long game: Evolution of clinical decision making throughout residency and fellowship.

BACKGROUND: The purpose of this study was to explore the trajectory of autonomy in clinical decision making. METHODS: We conducted a qualitative secondary analysis of interviews with 45 residents and fellows from the General Surgery and Obstetrics & Gynecology departments across all clinical postgraduate years (PGY) using convenience sampling. Each interview was recorded, transcribed and iteratively analyzed using a framework method. RESULTS: A total of 16 junior residents, 22 senior residents and 7 fellows participated in 12 original interviews. Early in training residents take their abstract ideas about disease processes and make them concrete in their applications to patient care. A transitional stage follows in which residents apply concepts to concrete patient care. Chief residents re-abstract their concrete technical and clinical knowledge to prepare for future surgical practice. CONCLUSIONS: Understanding where each learner is on this pathway will assist development of curriculum that fosters resident readiness for practice at each PGY level.

Efficiency of Increasing Prospective Resident Entrustment in the Operating Room.

BACKGROUND: Prospective resident entrustment (i.e., trust an attending surgeon intends to give to a resident in the near future) in the operating room (OR) closely associates with granted future autonomy. However, the process of determining resident entrustment takes time and effort. Thus, this study aimed to assess the efficiency of granting incremental resident entrustment for upcoming surgical cases. METHODS: We analyzed prospective resident entrustment of 6 chief residents in 76 cases of laparoscopic cholecystectomy, laparoscopic colectomy, ventral hernia, and inguinal hernia scored by attending surgeon, resident, and a surgeon observer. Matched direct costs and operative time were extracted from hospital billing. We assessed the efficiency of granting incremental prospective resident entrustment with direct cost per minute incurred in the evaluated case. Effect size was computed to assess the differences between groups. RESULTS: Sixty-three cases (82.9%) were matched; 47.6% (30/63) of matched cases received prospective resident entrustment score ≥ 4. The direct cost per minute increased in three procedures (laparoscopic cholecystectomy, laparoscopic colectomy, and ventral hernia) with increased intention of granting incremental resident entrustment. Inguinal hernia was the only procedure in which chiefs were entrusted with future independence while the direct cost per minute decreased. CONCLUSIONS: Our findings demonstrate more time and effort are required (except for inguinal hernia) for residents to be entrusted with increased independence in the future. Faculty and resident development programs are recommended to improve the efficiency of the process of granting incremental operative entrustment to optimize resident training quality and cost of care delivery.

Predicting prospective resident entrustment: From evaluation to action.

OBJECTIVE: We aimed to identify potential variables predictive of a resident achieving faculty future entrustment as a way to enhance attending surgeons' planning of teaching in the operating room leading to improved resident operative autonomy in practice. METHODS: We reviewed 273 resident performance evaluations from 91 surgical cases that were collected from 11 general surgery chief residents and 16 attending surgeons between April 2018 and June 2019 using a validated evaluation instrument. The primary outcome measure was prospective resident entrustment estimated by the rater for future similar cases. We used descriptive statistics and the boosted tree analysis model to find potential predictors for the outcome measure and examine test-retest reliability by procedure. RESULTS: Step-specific guidance (r = 0.77, p < 0.0001) was the variable most highly associated with prospective resident entrustment in bivariate linear analysis. The boosted tree analysis demonstrated step-specific guidance was the strongest predictor for prospective resident entrustment in the OR, and its predictive importance was much higher than the overall guidance (0.64 > 0.18). Test-retest reliability was from 0.93 to 0.98 across procedures, indicating the likelihood that attending surgeons granted future autonomy complied with their evaluation of prospective resident entrustment was high. CONCLUSIONS: By assessing step-specific guidance, attending surgeons can reliably judge residents' future entrustment and potentially better plan for operative teaching/supervision that may lead to granting a surgical resident operative autonomy on similar cases in the future. Our findings provide insight into prospective faculty development of surgical teaching aimed at improving resident readiness for independent practice.

A Novel Operative Coaching Program for General Surgery Chief Residents Improves Operative Efficiency.

INTRODUCTION: We evaluated the effect of an operative coaching (OC) model on general surgery chief residents' operative efficiency (OE) measured by operative times. We hypothesized that higher levels of entrustment surgeons intend to offer resident in future similar cases are associated with improved OE. MATERIALS AND METHODS: From July 2018 to June 2019, we used a validated instrument to score prospective resident entrustment in 228 evaluations of 6 chief residents during 12 OC sessions each (3 lap colectomy, 3 lap cholecystectomy, 3 ventral hernia, 3 inguinal hernia). Operative times of matched case CPT codes performed by coached chiefs (N = 500) were matched via CPT code to the cases of uncoached chiefs in the academic year 2016-2017 (N = 478). Statistical analysis was performed using Pearson correlation and one-way ANOVA. RESULTS: Prospective entrustment scores from coached chief residents were associated with significantly shorter operative times in matched complex cases (CC) (r = -0.58, p = 0.0047). A similar trend was observed in noncomplex cases (NCC) (r = -0.29, p = 0.18). Compared to the historical cohort, coached chief residents showed a decrease in mean operative time during complex cases (p = 0.0008, d = 0.44), but an increase in mean operative times for noncomplex cases (p < 0.0001, d = 0.33). CONCLUSIONS: An OC model improves chief residents' prospective entrustment leading to increased OE in cases with greater levels of operative complexity, showing a decrease in mean operative time compared to uncoached residents in certain procedures. This is the first report showing formal coaching may be a method to enhance chief resident OE.

Complex hepato-pancreato-biliary caseload during general surgery residency training: are we adequately training the next generation?

BACKGROUND: Information on procedure volume of graduating chief residents (GCRs) for hepato-pancreato-biliary(HPB) surgical procedures may inform assessments of resident training. This study sought to characterize trends in operative volumes over a 19-year period to define the degree to which general surgery residents gain exposure to HPB procedures during training. METHODS: The ACGME was queried for all HPB operations performed by GCR between 2000-2018. Total procedures as well as means and fold change was calculated and reported for each year. RESULTS: Between 2000-2018, the number of general surgery residency programs varied between 240 and 254. A total of 411,383 HPB procedures (36.2% liver, 42.8% pancreas, 21% complex biliary) were performed by 22,229 GCR. Each year of the study, GCR had similar mean number total procedures:liver 7.4, pancreas 8.7, and complex biliary 4.4. For liver procedures there was no difference in the fold change over time, however for pancreas there was an increase in the fold change from 2.25 to 3.25. CONCLUSION: Most GCRs are graduating with a low number of HPB procedures and trends suggesting a decrease in the mean number of procedures per GCR and an increasing variability among residents.

Redefining the Surgical Council of Resident Education (SCORE) Curriculum: A Comparison with the Operative Experiences of Graduated General Surgical Residents.

Our objective was to investigate the number and classify surgical operations performed by general surgery residents and compare these with the updated Surgical Council on Resident Education (SCORE) curriculum. We performed a retrospective review of logged surgical cases from general surgical residents who completed training at a single center from 2011 to 2015. The logged cases were correlated with the operations extracted from the SCORE curriculum. Hundred and fifty-one procedures were examined; there were 98 "core" and 53 "advanced" cases as determined by the SCORE. Twenty-eight residents graduated with an average of 1017 major cases. Each resident completed 66 (67%) core cases and 17 (32%) advanced cases an average of one or more times with 39 (40%) core cases and 6 (11%) advanced cases completed five or more times. Core procedures that are infrequently or not performed by residents should be identified in each program to focus on resident education.

Does Delaying Surgical Resection After Neoadjuvant Chemoradiation Impact Clinical Outcomes in Locally Advanced Rectal Adenocarcinoma?: A Single-Institution Experience.

OBJECTIVES: Surgical resection for locally advanced rectal adenocarcinoma commonly occurs 6 to 10 weeks after completion of neoadjuvant chemoradiation (nCRT). We sought to determine the optimal timing of surgery related to the pathologic complete response rate and survival endpoints. METHODS: The study is a retrospective analysis of 92 patients treated with nCRT followed by surgery from 2004 to 2011 at our institution. Univariate and multivariate analyses were performed to assess the impact of timing of surgery on locoregional control, distant failure (DF), disease-free survival, and overall survival (OS). RESULTS: Time-to-surgery was ≤8 weeks (group A) in 72% (median 6.1 wk) and >8 weeks (group B) in 28% (median 8.9 wk) of patients. No significant differences in patient characteristics, locoregional control, or pathologic complete response rates were noted between the groups. Univariate analysis revealed that group B had significantly shorter time to DF (group B, median 33 mo; group A, median not reached, P=0.047) and shorter OS compared with group A (group B, median 52 mo; group A, median not reached, P=0.03). Multivariate analysis revealed that increased time-to-surgery showed a significant increase in DF (HR=2.96, P=0.02) and trends toward worse OS (HR=2.81, P=0.108) and disease-free survival (HR=2.08, P=0.098). CONCLUSIONS: We found that delaying surgical resection longer than 8 weeks after nCRT was associated with an increased risk of DF. This study, in combination with a recent larger study, questions the recent trend in promoting surgical delay beyond the traditional 6 to 10 weeks. Larger, prospective databases or randomized studies may better clarify surgical timing following nCRT in rectal adenocarcinoma.

Defining payments associated with the treatment of colorectal cancer.

BACKGROUND: While bundled payments aim to reduce variations in health care spending across the continuum of care, data reporting on variations in payments for privately insured patients undergoing treatment for colon cancer (CC) are lacking. The current study sought to characterize variations in payments received for the treatment of CC using a cohort of commercially insured patients. METHODS: Patients who underwent a colectomy for CC were identified using the MarketScan Database for 2010-2014. Multivariable regression analysis was used to calculate and compare risk-adjusted payments between patients. RESULTS: A total of 18,337 patients were identified who met inclusion criteria. The median risk-adjusted payment for surgery was $26,408 (IQR: $19,193-$38,037) ranging from $19,762 (IQR: $15,595-$25,636) among patients in the lowest quartile of payments to $33,809 (IQR: $24,783-$48,254) for patients in the highest (+△71.1%). The median risk-adjusted payment for chemotherapy was $70,090 (IQR: $57,813-$83,216); compared with patients in the lowest quartile of payments, payments associated with chemotherapy were 40.4% higher among patients in the highest quartile of payments (Q1 versus Q4: $56,827 [IQR: 49,173-65,353] versus $79,801 [IQR: 67,270-90,999]). When stratified by treatment type, patients in the highest two quartiles of risk-adjusted payments accounted for a total of 58.5% of all payments, whereas patients in the lower two quartiles of risk-adjusted payments accounted for only 41.5% of all payments. A younger patient age, increasing patient comorbidity and undergoing an open operation were associated with higher overall payments. CONCLUSIONS: Wide variations in payments exist for the treatment for colon cancer. Episode-based bundle payments for surgery and chemotherapy may differentially impact reimbursement for CC.

Crospovidone and Microcrystalline Cellulose: A Novel Description of Pharmaceutical Fillers in the Gastrointestinal Tract.

Crospovidone and microcrystalline cellulose (MCC) are pharmaceutical fillers well known in the pulmonary pathology literature. Fillers are inactive substances incorporated into medications to facilitate drug delivery. By examining 545 consecutive gastrointestinal surgical specimens from 302 patients between September 11, 2015 and October 23, 2015, we identified the fillers in 29 specimens from 26 patients. The control group consisted of an equal number of consecutive site-matched specimens collected during this same time. Pertinent clinicopathologic data were analyzed, and 1 case was subject to special stains. To confirm the histologic diagnosis, a variety of fillers and medications common to the patients were processed. The fillers were found in 9% of all patients, and there were no specific clinicopathologic associations. In the gastrointestinal tract, crospovidone is nonbirefringent and has a coral shape with each segment composed of a pink core and purple coat; MCC is brightly birefringent with matchstick shape and clear color. Identical material was seen in the processed crospovidone and MCC powders, as well as oxycodone-acetaminophen and omeprazole tablets. In summary, crospovidone and MCC are common, biologically inert, and they are most often seen in the small bowel. Their presence outside of the luminal bowel may serve as a surrogate marker for perforation. Awareness of their morphology is important to distinguish fillers from parasites, calcifications, and other medications, particularly those linked to mucosal injury. We report the unique histomorphologic profile of these fillers as a helpful diagnostic aide, and caution that the fillers have slightly divergent features when compared with those described in the lung.

An Analysis of Operative Experiences of Junior General Surgical Residents and Correlation With the SCORE Curriculum.

OBJECTIVE: Junior surgical resident education at academic institutions is traditionally focused to preoperative and postoperative patient management. Our objective was to investigate the number and type of surgical procedures performed by junior general surgery residents in comparison with the American Board of Surgery requirements and the Surgical Council on Resident Education (SCORE) curriculum. DESIGN: This was a retrospective study using the Accreditation Counsel for Graduate Medical Education (ACGME) operative case logs of junior surgical residents. SETTING: The Ohio State University Wexner Medical Center, Columbus, OH; a tertiary academic medical center. PARTICIPANTS: We performed, an institutional review board approved, retrospective review of logged surgical cases from general surgical residents during postgraduate year (PGY) 1 and 2 from 2009 to 2015 at an academic medical center. Summary case logs were accessed from the ACGME. Procedures were extracted from the SCORE curriculum and correlated to corresponding ACGME defined procedures for total cases, major cases, and endoscopy. Minor cases and patient care cases were excluded as they were not clearly defined on the category report. SCORE procedures were excluded if there was not a corresponding ACGME procedure on the summary report. SCORE procedures and ACGME procedures were combined with each other if there was overlap with correlation. Statistics were performed on individual and total resident data. One-sample student's t-test was used to compare total number of cases logged with the 250 case log ABS requirement and to compare the total major cases and endoscopy performed with those represented on SCORE. RESULTS: Overall, 26 residents completed both PGY-1 and 2 years from 2009 to 2015, and remained at the same institution for case logs to be accessed during the study period. A total of 21 residents (80.76%) completed 250 cases or more after their first 2 years of residency. Across all years, the mean case log was 349 cases (p = 0.20), and was statistically more than than 250 cases in 3 of the 5 class years. Junior residents completed a total mean of 312 major and endoscopy cases (89%) at the end of 2 years, which was statistically higher than the 75% testing hypothesis across all years (p < 0.01). Of major and endoscopy cases performed in total by the completion of the PGY-2 year, a mean of 275 cases (88%) were included in the SCORE curriculum. Using one-sample t-test, SCORE procedures represented more than 85% of the major and endoscopy cases logged (p < 0.01). Of all major and endoscopy cases logged that correlate to a SCORE procedure, 95% were found to be "core" and 5% were "advanced." CONCLUSIONS: Our study demonstrates that junior surgical residents meet the 250 case log requirement put forth by the ABS, and most major procedures and endoscopy performed correspond with the core cases of the SCORE curriculum at our institution. This study aid in the confirmation of the SCORE curriculum for junior residents, and those procedures which should be designated as core.

Two Patients with Fulminant Clostridium difficile Enteritis Who Had Not Undergone Total Colectomy: A Case Series and Review of the Literature.

Introduction. Clostridium difficile is the most common cause of healthcare associated infectious diarrhea, and its most common clinical manifestation is pseudomembranous colitis. Small bowel enteritis is reported infrequently in the literature and typically occurs only in patients who have undergone ileal pouch anastomosis due to inflammatory bowel disease or total abdominal colectomy for other reasons. Presentation of Cases. We report here two cases in which patients developed small bowel C. difficile enteritis in the absence of these underlying conditions. Discussion. Neither patient had underlying inflammatory bowel disease and both had a significant amount of colon remaining. Conclusion. These two cases demonstrate that small bowel C. difficile enteritis should be included in the differential diagnosis of patients on antibiotic therapy who demonstrate signs and symptoms of worsening abdominal disease during their postoperative course, even if they lack the major predisposing factors of inflammatory bowel disease or history of total colectomy.

Retrospective Evaluation of Laparoscopic Versus Open Hartmann's Reversal: A Single-Institution Experience.

PURPOSE: Restoration of intestinal continuity after Hartmann's procedure has significant associated morbidity. There has been a trend toward increasing utilization of laparoscopy in colorectal surgery, with improvements in short-term outcomes. This study evaluates our experience with laparoscopic Hartmann's procedure reversal. METHODS: All patients who underwent laparoscopic and open reversal of Hartmann's procedure between 2007 and 2010 were reviewed. Demographics, length of stay, postoperative morbidity, and mortality were compared between the 2 groups. RESULTS: Nineteen patients underwent laparoscopic Hartmann's reversal and 62 underwent open reversal. There were no statistically significant differences in demographics, comorbidities, mean operative times, blood loss, reoperation, and readmission rates between the groups. The laparoscopic group had a shorter length of hospitalization (5.7 vs. 7.9 d, P<0.01). CONCLUSIONS: Laparoscopic reversal of Hartmann's pouch is a safe and feasible alternative to the open reversal technique. Patients who undergo the laparoscopic technique have a shorter length of hospital stay.

Liposome Bupivacaine for Postsurgical Analgesia in Adult Patients Undergoing Laparoscopic Colectomy: Results from Prospective Phase IV Sequential Cohort Studies Assessing Health Economic Outcomes.

BACKGROUND: Opioid-based postsurgical analgesia exposes patients undergoing laparoscopic colectomy to elevated risk for gastrointestinal motility problems and other opioid-related adverse events (ORAEs). The purpose of our research was to investigate postsurgical outcomes, including opioid consumption, hospital length of stay, and ORAE risk associated with a multimodal analgesia regimen, employing a single administration of liposome bupivacaine as well as other analgesics that act by different mechanisms. METHODS: We analyzed combined results from 6 Phase IV, prospective, single-center studies in which patients undergoing laparoscopic colectomy received opioid-based intravenous patient-controlled analgesia (PCA) or multimodal analgesia incorporating intraoperative administration of liposome bupivacaine. As-needed rescue therapy was available to all patients. Primary outcome measures were postsurgical opioid consumption, hospital length of stay, and hospitalization costs. Secondary measures included time to first rescue opioid use, patient satisfaction with analgesia (assessed using a 5-point Likert scale), and ORAEs. RESULTS: Eighty-two patients underwent laparoscopic colectomy and did not meet intraoperative exclusion criteria (PCA n = 56; multimodal analgesia n = 26). Compared with the PCA group, the multimodal analgesia group had significantly lower mean total postsurgical opioid consumption (96 vs 32 mg, respectively; P < 0.0001) and shorter median postsurgical hospital length of stay (3.0 vs 4.0 days; P = 0.0019). Geometric mean costs were $11,234 and $13,018 in the multimodal analgesia and PCA groups, respectively (P = 0.2612). Median time to first rescue opioid use was longer in the multimodal analgesia group versus PCA group (1.1 hours vs 0.6 hours, respectively; P=0.0003). ORAEs were experienced by 41% of patients receiving intravenous opioid PCA and 8% of patients receiving multimodal analgesia (P = 0.0019). Study limitations included use of an open-label, nonrandomized design; small population size; and the inability to isolate treatment-related effects specifically attributable to liposome bupivacaine. CONCLUSIONS: Compared with intravenous opioid PCA, a liposome bupivacaine-based multimodal analgesia regimen reduced postsurgical opioid use, hospital length of stay, and ORAEs, and may lead to improved postsurgical outcomes following laparoscopic colectomy.

Evolution of practice gaps in gastrointestinal and endoscopic surgery: 2012 report from the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Continuing Education Committee.

BACKGROUND: In an effort to fulfill its charge to develop and maintain a comprehensive educational program to serve the members of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), the SAGES Continuing Education Committee (CEC) reports a summary of findings related to its evaluation of the 2012 SAGES annual meeting. METHODS: All attendees to the 2012 annual meeting had the opportunity to complete an immediate postmeeting questionnaire as part of their continuing medical education (CME) certification in which they identified up to two learning themes, answered questions related to potential practice change items that are based on those learning themes, and complete a needs assessment related to important learning topics for future meetings. In addition, participants in the postgraduate and hands-on courses were asked to complete questions about case volume and comfort levels related to procedures/topics in those courses. All respondents to this initial survey were sent a 3-month follow-up questionnaire in which they were asked how successfully they had implemented the intended practice changes and what, if any, barriers they encountered. Postgraduate and hands-on course participants completed case volume and comfort level questions. Descriptive statistical analysis of this deidentified data was undertaken. RESULTS: Response rates were 42% and 56% for CME-eligible attendees/respondents for the immediate postmeeting and 3-month follow-up questionnaires, respectively. Top learning themes for respondents were Bariatric, Hernia, Foregut, and Colorectal. Improving minimally invasive surgical (MIS) technique and managing complications related to MIS procedures were top intended practice changes. Partial implementation was common with top barriers including cost restrictions, lack of institutional support, and lack of time. CONCLUSIONS: The 2012 annual meeting analysis provides insight into educational needs among respondents and will help with planning content for future meetings.
