RESUMO
INTRODUCTION: Resident physicians play an important role in teaching the next generation of health-care providers, yet limited research has explored factors influencing effective teaching, such as preresidency experiences or barriers within residency. This study examines residents' prior teaching experience, its correlation with teaching attitudes, and identifies potential barriers to sustained teaching engagement. METHODS: This cross-sectional study surveyed residents across multiple specialties at a single academic center. The survey assessed preresidency teaching experience, perceived barriers, and attitudes toward teaching. Univariate and multivariate analyses identified differences in teaching attitudes based on prior teaching experience and gender. RESULTS: Ninety-two residents across 11 specialties participated (52.2% female). Internal Medicine (28.3%) and General Surgery (26.1%) had the highest representation. Two-thirds of respondents (69.6%) had formal teaching experience before residency. After adjustment, prior teaching experience and male gender were associated with feeling prepared to teach medical students (P = 0.014 and P = 0.001). Male gender was also linked to confidence in teaching material on the wards (P = 0.015). Barriers identified included time constraints (73.9%), lack of content clarity (28.3%), and uncertainty about teaching methods (33.7%). CONCLUSIONS: Residents with prior teaching experience exhibit higher levels of preparedness, content clarity, and confidence in their teaching abilities, underscoring the importance of teaching experience before residency. This study also identified significant barriers to effective teaching, including time constraints, lack of content clarity, uncertainty about teaching methods, and perceived disinterest from medical students. Addressing these barriers is essential for optimizing medical student education.
RESUMO
INTRODUCTION: The surgical clerkship is a formative experience in the medical school curriculum and can leave a lasting impression on students' perception of surgery. Given the historical negative stereotypes of surgeons, the clerkship represents an opportunity to impact students in a meaningful way. METHODS: Our institution developed a program in which research residents can serve as junior clerkship coordinators and educators; working closely with medical students on their surgery clerkship. At the end of their clerkship, students were administered a survey with Likert-scale and free text responses regarding satisfaction with the rotation, lectures, feedback, and value of the clerkship. Student survey results were compared before (2015-2016) and after (2017-2019) the implementation of the scholar program with nonparametric statistical analysis and qualitative text analysis. RESULTS: A total of 413 students responded to the survey with no significant difference in response rate by term (P = 0.88). We found no statistical difference with respect to overall course perception (92.3% versus 91.2%, P = 0.84), but a statistically significant difference was noted for the clarity of the provided written clerkship materials (80.3% versus 91.3%, P = 0.02) and usefulness of the feedback (57.5% versus 78.7%, P = 0.01). Qualitative analysis demonstrated an overall positive shift in perception of the clerkship, improvement in the course materials, and organization. CONCLUSIONS: The scholar program was overall well received by the students with improvements in certain aspects of the clerkship: organization, feedback, and course materials. This program represents a potential strategy to improve certain portions of the medical school clerkship experience.

INTRODUCTION: Responses to COVID-19 within medical education prompted significant changes to the surgical clerkship. We analyzed the changes in medical student end of course feedback before and after the COVID-19 outbreak. METHODS: Postclerkship surveys from 2017 to 2022 were analyzed including both Likert scale data and free text, excluding the COVID outbreak year 2019-2020. Likert scale questions were compared between pre-COVID (2017-2019) and COVID-era cohorts (2020-2022) with the Mann-Whitney U-test. Free-text comments were analyzed using both thematic analysis and natural language processing including sentiment, word and phrase frequency, and topic modeling. RESULTS: Of the 483 medical students surveyed from 2017 to 2022, 297 responded (61% response rate) to the included end of clerkship surveys. Most medical students rated the clerkship above average or excellent with no significant difference between the pre-COVID and COVID-era cohorts (70.4% Versus 64.8%, P = 0.35). Perception of grading expectations did significantly differ, 51% of pre-COVID students reported clerkship grading standards were almost always clear compared to 27.5% of COVID-era students (P = 0.01). Pre-COVID cohorts more frequently mentioned learning and feedback while COVID-era cohorts more frequently mentioned case, attending, and expectation. Natural language processing topic modeling and formal thematic analysis identified similar themes: team, time, autonomy, and expectations. CONCLUSIONS: COVID-19 presented many challenges to undergraduate medical education. Despite many changes, there was no significant difference in clerkship satisfaction ratings. Unexpectedly, the greater freedom and autonomy of asynchronous lectures and choice of cases became a highlight of the new curriculum. Future research should investigate if there are similar associations nationally with a multi-institutional study.

BACKGROUND: Rectourethral fistulas are a rare yet severe complication of prostate surgery, pelvic irradiation therapy, or both. Multiple surgical repairs exist with widely varying success rates. OBJECTIVE: This study aimed to present our institutional multidisciplinary algorithm for rectourethral fistula repair and its outcomes. DESIGN: This was a retrospective, pre- and postintervention, quasi-experimental design, comparing the frequency of fistula healing and reversal of urinary and fecal diversion before and after implementation of our algorithm. SETTING: All patients who presented to the Duke University with rectourethral fistula between 2002 and 2019 were included. PATIENTS: This study included 79 patients treated for rectourethral fistula: 36 prealgorithm and 43 postalgorithm. INTERVENTIONS: Our multidisciplinary algorithm was implemented in 2012. Patients with fistulas <2 cm and without history of radiation therapy underwent York-Mason repair, whereas those with fistulas 2-3 cm or with prior irradiation underwent transperineal repair with gracilis flap interposition. Those with nonrepairable fistulas (>3 cm or fixed tissues) underwent pelvic exenteration. Before repair, the algorithm recommended all patients to undergo urinary and bowel diversion. MAIN OUTCOME MEASURES: The 2 primary outcomes were rectourethral fistula healing, defined as both radiographic and clinical resolutions, and reversal of urinary and fecal diversions. RESULTS: Frequency of fistula healing improved in the post- versus prealgorithm subgroups (93.1% vs 71.9%; p = 0.04). The relative risk of fistula healing pre- versus postintervention was 0.77 (0.61-0.98; p = 0.04) among the overall cohort. Eighteen patients (22.8%) underwent pelvic exenteration for nonrepairable fistulas and were not included in primary outcome measures. LIMITATIONS: Limitations include the study's retrospective nature, possible selection bias because of algorithmic patient selection, and small sample size. CONCLUSIONS: Implementation of a multidisciplinary institutional algorithm improved rectourethral fistula repair success with high rates of ostomy reversal. Proper patient selection and multidisciplinary involvement are paramount to this success. See Video Abstract at http://links.lww.com/DCR/B955 . RESULTADOS DE UN ABORDAJE ALGORTMICO Y MULTIDISCIPLINARIO PARA LA REPARACIN DE FSTULAS RECTOURETRALES UN ESTUDIO CUASIEXPERIMENTAL PREVIO Y POSTERIOR A LA INTERVENCIN: ANTECEDENTES:Las fístulas rectouretrales son una complicación rara pero grave de la cirugía de próstata, la radiación pélvica o ambas. Existen múltiples reparaciones quirúrgicas con tasas de éxito muy variables.OBJETIVO:Presentar el algoritmo multidisciplinario de nuestra institución para la reparación de fístulas rectouretrales y sus resultados.DISEÑO:Este fue un diseño retrospectivo, previo y posterior a la intervención, cuasiexperimental, que comparó la frecuencia de curación de la fístula y la reversión de la derivación urinaria y fecal antes y después de la implementación de nuestro algoritmo.ESCENARIO:Se incluyeron todos los pacientes que acudieron a Duke con fístula rectouretral entre 2002 y 2019.PACIENTES:Setenta y nueve pacientes fueron tratados por fístula rectouretral; 36 pre-algoritmo y 43 post-algoritmo.INTERVENCIONES:Nuestro algoritmo multidisciplinario se implementó en 2012. Los pacientes con fístulas <2 cm y sin antecedentes de radiación se sometieron a reparación de York-Mason, mientras que aquellos con fístulas de 2-3 cm o radiación pélvica previa se sometieron a reparación transperineal con interposición de colgajo de gracilis. Aquellos con fístulas no reparables (> 3 cm o tejidos fijos) fueron sometidos a exenteración pélvica. Antes de la reparación, el algoritmo recomomendó que todos los pacientes se sometieran a una derivación urinaria y fecal.PRINCIPALES MEDIDAS DE RESULTADO:Los dos resultados primarios fueron la curación de la fístula rectouretral, definida como la resolución radiográfica y clínica, y la reversión de las derivaciones urinaria y fecale.RESULTADOS:La frecuencia de curación de la fístula mejoró en el subgrupo post-algoritmo vs. pre-algoritmo (93.1% vs. 71.9%, p = 0.04). El riesgo relativo de curación de la fístula antes de la intervención en comparación con después de la intervención fue de 0.77 (0.61-0.98, p = 0.04) entre la cohorte general. Dieciocho pacientes (22.8%) se sometieron a exenteración pélvica por fístulas no reparables y, por lo tanto, no se incluyeron en las medidas de resultado primarias.LIMITACIONES:Las limitaciones de este estudio incluyen su naturaleza retrospectiva, posible sesgo de selección debido a la selección algorítmica de pacientes y un tamaño de muestra pequeño.CONCLUSIONES:La implementación de un algoritmo institucional multidisciplinario mejoró el éxito en la reparación de la fístula rectouretral con altas tasas de reversión de la ostomía. La selección adecuada de pacientes y la participación multidisciplinaria son fundamentales para este éxito. Consulte Video Resumen en http://links.lww.com/DCR/B955 .

BACKGROUND: As the use of minimally invasive techniques in colorectal surgery has become increasingly prevalent, concerns remain about the oncologic effectiveness and long-term outcomes of minimally invasive low anterior resection (MI-LAR) for the treatment of rectal cancer. STUDY DESIGN: The 2010-2015 National Cancer Database (NCDB) Participant Data Use File was queried for patients undergoing elective open LAR (OLAR) or MI-LAR for rectal adenocarcinoma. A 1:1 propensity match was performed on the basis of demographics, comorbidity, and tumor characteristics. Outcomes were compared between groups and Cox proportional hazard modeling was performed to identify independent predictors of mortality. A subset analysis was performed on high-volume academic centers. RESULTS: 35,809 patients undergoing LAR were identified of whom 18,265 (51.0%) underwent MI-LAR. After propensity matching, patients receiving MI-LAR were less likely to have a positive circumferential radial margin (CRM) (5.5% vs. 6.6%, p = 0.0094) or a positive distal margin (3.6% vs. 4.6%, p = 0.0022) and had decreased 90-day all-cause mortality (2.0% vs. 2.6%, p = 0.0238). MI-LAR resulted in decreased hospital length of stay (5 vs. 6 days, p < 0.0001) but a greater rate of 30-day readmission (7.6% vs. 6.5%, p = 0.0054). Long-term overall survival was improved with MI-LAR (79% vs. 76%, p < 0.0001). Cox proportional hazard modeling demonstrated a decreased risk of mortality with MI-LAR (HR 0.859, 95% CI 0.788-0.937). CONCLUSION: MI-LAR is associated with improvement in CRM clearance and long-term survival. In the hands of experienced surgeons with advanced laparoscopy skills, MI-LAR appears safe and effective technique for the management of rectal cancer.

BACKGROUND: Primary perineal closure following abdominal perineal resection (APR) is reported to have a wound complication rate as high as 66%, whereas flap reconstruction reduces wound complications to 15% to 35%. A modified de-epithelialized V-Y fasciocutaneous flap aims to further improve results in this patient population. METHODS: To study the breaking force of a simple interrupted suture in either skin or subcutaneous fat, various quantitative assessments were performed in a porcine flap model using uniaxial static tensile testing with an Instron tensiometer, with a single or triple row of 3 Vicryl sutures in both skin and fat.An outcomes analysis was performed in 24 patients who underwent modified V-Y flap reconstruction after APR. Primary outcome was wound complications including infection, dehiscence, seroma, hematoma, and pelvic fluid collections. RESULTS: Tensile strength of sutures anchored in skin was found to be up to 8 times stronger than sutures anchored in subcutaneous fat in a single row and 3 times as strong in 3 rows (breaking force, 500.2 N vs 263.7 N). In our patient cohort of 24 irradiated cancer patients, 10 (42%) had wound healing complications. Wound dehiscence of various degrees accounted for 80% of these complications. Five patients with wound complications (50%) had associated pelvic fluid collections (infection, 1; wound dehiscence, 4). Minor dehiscence was more likely to occur after suture removal and less likely to be associated with pelvic collections compared to patients with major dehiscence. Our study yields total complication rates lower than what is reported in the literature for anterolateral thigh or gracilis flap including much lower infection rates, and almost similar results to the commonly used vertical rectus myocutaneous muscle. CONCLUSION: Tension-free de-epithelialized V-Y flap use after APR effectively reconstructs the defect while eliminating an additional donor site. Benchtop studies suggest enhanced flap integrity yielded by layered closure. Wound complications can be managed with local care in their majority (90%). Staggering or delaying suture removal can decrease minor dehiscence. Based on analysis of our results, review of the literature and consideration of donor site morbidity, we believe that modified V-Y flap is the best approach for APR reconstruction in irradiated patients.

Surgical site infection (SSI) following colorectal surgery is associated with worse postoperative outcomes, longer length of stay, and higher rates of readmission. SSI rates have been established as a surrogate metric for the overall quality of surgical care and are intricately tied to financial incentives and the public reputation of an institution. While risk factors and prevention mechanisms for SSI are well established, the rates of SSI remain high. This article discusses the clinical and economic impact of SSI and strategies for mitigating the risk of SSI through bundled prevention practices.
RESUMO
BACKGROUND: Surgeons present patients with complex information at the perioperative appointment. Emotions likely play a role in surgical decision-making, and disgust is an emotion of revulsion at a stimulus that can lead to avoidance. OBJECTIVE: The purpose of this study was to determine the impact of disgust on intention to undergo surgical resection for colorectal cancer and recall of perioperative instructions. DESIGN: This was a cross-sectional observational study conducted online using hypothetical scenarios with nonpatient subjects. SETTINGS: The study was conducted using Amazon's Mechanical Turk. PATIENTS: Survey respondents were living in the United States. MAIN OUTCOME MEASURES: Surgery intention and recall of perioperative instructions were measured. RESULTS: A total of 319 participants met the inclusion criteria. Participants in the experimental condition, who were provided with detailed information and pictures about stoma care, had significantly lower surgery intentions (mean ± SD, 4.60 ± 1.15) compared with the control condition with no stoma prompt (mean ± SD, 5.14 ± 0.91; p = 0.05) and significantly lower recall for preoperative instructions (mean ± SD, 13.75 ± 2.38) compared with the control condition (mean ± SD, 14.36 ± 2.19; p = 0.03). Those within the experimental conditions also reported significantly higher state levels of disgust (mean ± SD, 4.08 ± 1.74) compared with a control condition (mean ± SD, 2.35 ± 1.38; p < 0.001). State-level disgust was found to fully mediate the relationship between condition and recall (b = -0.31) and to partially mediate the effect of condition on surgery intentions (b = 0.17). LIMITATIONS: It is unknown whether these results will replicate with patients and the impact of competing emotions in clinical settings. CONCLUSIONS: Intentions to undergo colorectal surgery and recall of preoperative instructions are diminished in patients who experience disgust when presented with stoma information. Surgeons and care teams must account for this as they perform perioperative counseling to minimize interference with recall of important perioperative information.

BACKGROUND: Controversy exists regarding current National Comprehensive Cancer Network guidelines, which recommend local excision for rectal carcinoids ≤2 cm and radical resection for tumors >2 cm. Given the limited data examining optimal surgical approach for these lesions, we queried a national database to determine the impact of extent of resection on survival. METHODS: Patients undergoing treatment for clinical stage I and II rectal carcinoid (RC) were identified from the National Cancer Data Base (1998-2012). The association between extent of surgery, tumor size, and the likelihood of pathologic lymph node positivity was examined. Kaplan-Meier analysis was used to compare overall survival. RESULTS: In total, 1900 patients were identified, of whom 1644 (86.5%) were treated with local excision, and 256 (13.5%) were treated with radical resection. A significant majority of patients with tumors ≤2.0 cm (89.0%) and nearly half with tumors 2.1-4.0 cm (44.8%) or >4.0 cm (45.8%) underwent local excision. Nodal positivity was correlated with tumor size (7.1% positivity with ≤2.0 cm tumors, 31.3% with 2.1-4.0 cm tumors, and 50.0% with >4 cm tumors). However, 5-y survival was equivalent between surgical approaches for tumors ≤2 cm (93.0% versus 93.0%) and tumors 2.1-4.0 cm (76.0% versus 76.0%). CONCLUSIONS: We demonstrate in early-stage RC that nearly half of intermediate and large tumors are being treated with local excision outside National Comprehensive Cancer Network guidelines. In addition, radical resection does not appear to be associated with improved overall survival for tumors of any size. These findings suggest that the preferred approach to early-stage RCs without aggressive biological characteristics is local excision due to the decreased morbidity and mortality versus radical resection.

OBJECTIVE: To determine the impact of race and insurance on use of minimally invasive (MIS) compared with open techniques for rectal cancer in the United States. BACKGROUND: Race and socioeconomic status have been implicated in disparities of rectal cancer treatment. METHODS: Adults undergoing MIS (laparoscopic or robotic) or open rectal resections for stage I to III rectal adenocarcinoma were included from the National Cancer Database (2010-2012). Multivariate analyses were employed to examine the adjusted association of race and insurance with use of MIS versus open surgery. RESULTS: Among 23,274 patients, 39% underwent MIS and 61% open surgery. Overall, 86% were white, 8% black, and 3% Asian. Factors associated with use of open versus MIS were black race, Medicare/Medicaid insurance, and lack of insurance. However, after adjustment for patient demographic, clinical, and treatment characteristics, black race was not associated with use of MIS versus open surgery [odds ratio [OR] 0.90, P = 0.07). Compared with privately insured patients, uninsured patients (OR 0.52, P < 0.01) and those with Medicare/Medicaid (OR 0.79, P < 0.01) were less likely to receive minimally invasive resections. Lack of insurance was significantly associated with less use of MIS in black (OR 0.59, P = 0.02) or white patients (OR 0.51, P < 0.01). However, among uninsured patients, black race was not associated with lower use of MIS (OR 0.96, P = 0.59). CONCLUSIONS: Insurance status, not race, is associated with utilization of minimally invasive techniques for oncologic rectal resections. Due to the short-term benefits and cost-effectiveness of minimally invasive techniques, hospitals may need to improve access to these techniques, especially for uninsured patients.

BACKGROUND: Practice guidelines differ in their support of adjuvant chemotherapy use in patients who received preoperative chemoradiation for rectal cancer. OBJECTIVE: The purpose of this study was to evaluate the impact of adjuvant chemotherapy among patients with locally advanced rectal cancer who received neoadjuvant chemoradiation and surgery. DESIGN: This was a retrospective study. Multivariable Cox proportional hazard modeling was used to evaluate the adjusted survival differences. SETTINGS: Data were collected from the National Cancer Database. PATIENTS: Adults with pathologic stage II and III rectal adenocarcinoma who received neoadjuvant chemoradiation and surgery were included. MAIN OUTCOME MEASURES: Overall survival was measured. RESULTS: Among 12,696 patients included, 4023 (32%) received adjuvant chemotherapy. The use of adjuvant chemotherapy increased over the study period from 23% to 36%. Although older age and black race were associated with a lower likelihood of receiving adjuvant chemotherapy, patients with higher education level and stage III disease were more likely to receive adjuvant chemotherapy (all p < 0.05). At 7 years, overall survival was improved among patients who received adjuvant chemotherapy (60% vs. 55%; p < 0.001). After risk adjustment, the use of adjuvant chemotherapy was associated with improved survival (HR = 0.81 (95% CI, 0.72-0.91); p < 0.001). In the subgroup of patients with stage II disease, survival was also improved among patients who received adjuvant chemotherapy (68% vs 58% at 7 y; p < 0.001; HR = 0.70 (95% CI, 0.57-0.87); p = 0.002). Among patients with stage III disease, the use of adjuvant chemotherapy was associated with a smaller but persistent survival benefit (56% vs 51% at 7 y; p = 0.017; HR = 0.85 (95% CI, 0.74-0.98); p = 0.026). LIMITATIONS: The study was limited by its potential for selection bias and inability to compare specific chemotherapy regimens. CONCLUSIONS: The use of adjuvant chemotherapy among patients with rectal cancer who received preoperative chemoradiation conferred a survival benefit. This study emphasizes the importance of adjuvant chemotherapy in the management of rectal cancer and advocates for its increased use in the setting of neoadjuvant therapy.

BACKGROUND: The handoff of medical information from one provider to another can be inefficient and error prone, potentially undermining patient safety. Although several tools for structuring handoffs exist, none provide a brief, standardized framework for ensuring that patient acuity is efficiently and reliably communicated. We aim to introduce and perform initial testing of the Clinical Acuity Shorthand System (CLASS) (Copyright 2015, Duke University. All rights reserved.) for surgery, a patient classification tool intended to facilitate efficient communication of key patient information during handoffs. MATERIALS AND METHODS: Surgical trainees at a single center were asked to perform an exercise involving application of CLASS to 10 theoretical patient scenarios and to then complete a brief survey. Responses were scored based on similarity to target answers. Performance was evaluated overall and between groups of trainees. Time required to complete the exercise was also determined and perceived utility of the system was assessed based on survey responses. RESULTS: The study task was completed by 17 participants. Mean time to task completion was 10.3 ± 8.4 min. Accuracy was not decreased, and was in fact superior, in junior trainees. Most respondents indicated that such a system would be feasible and could prevent medical errors. CONCLUSIONS: CLASS is a novel system that can be learned quickly and implemented readily by trainees and can be used to convey patient information concisely and with acceptable fidelity regardless of level of training. Further study examining application of this system on clinical surgical services is warranted.

OBJECTIVE: To examine survival of patients who underwent minimally invasive versus open low anterior resection (LAR) for rectal cancer. BACKGROUND: Utilization of laparoscopic and robotic LAR for rectal cancer has steadily increased. Short-term outcomes between these techniques and open surgery have shown equivalent results; however, survival outcomes are unknown. METHODS: Adults from the National Cancer Data Base undergoing LAR for rectal adenocarcinoma were identified. Patients were stratified by intent-to-treat into open (OLAR) or minimally invasive LAR (MI-LAR). Multivariable modeling was used to compare short-term outcomes and survival between MI-LAR and OLAR and between laparoscopic (LLAR) and robotic LAR (RLAR). RESULTS: Among 14,033 patients included, 57.8% underwent OLAR and 42.2% MI-LAR. After adjustment, MI-LAR was associated with shorter length of stay (Pâ<â0.001), but similar rates of positive margins, 30-day readmission, 30-day mortality, and use of adjuvant therapies (all Pâ>â0.05). At 36 months, there was no difference in adjusted risk of mortality between MI-LAR and OLAR (hazard ratio [HR] 0.88, Pâ=â0.089). In a subgroup analysis of LLAR versus RLAR, there were no differences in lymph node harvest, margin positivity, length of stay, readmission rate, 30-day mortality, or overall survival after adjustment (all Pâ>â0.05). CONCLUSIONS: Minimally invasive LAR for rectal cancer is associated with similar overall survival with the benefit of shorter hospitalization. Although the conversion rate is lower, robotic LAR is not associated with superior oncologic outcomes compared to laparoscopic LAR. Our findings support the ongoing adoption of minimally invasive techniques for rectal adenocarcinoma.

BACKGROUND: The optimal approach to patients with locally recurrent, non-metastatic rectal cancer is unclear. This study evaluates the outcomes and toxicity associated with pelvic re-irradiation. METHODS: Patients undergoing re-irradiation for locally recurrent, non-metastatic, rectal cancer between 2000 and 2014 were identified. Acute and late toxicities were assessed using common terminology criteria for adverse events version 4.0. Disease-related endpoints included palliation of local symptoms, surgical outcomes, and local progression-free survival (PFS), distant PFS and overall survival (OS) using the Kaplan-Meier method. RESULTS: Thirty-three patients met the criteria for inclusion in this study. Two (6 %) experienced early grade 3+ toxicity and seven (21 %) experienced late grade 3+ toxicity. Twenty-three patients presented with symptomatic local recurrence and 18 (78 %) reported symptomatic relief. Median local PFS was 8.7 (95 % CI 3.8-15.2) months, with a 2-year rate of 15.7 % (4.1-34.2), and median time to distant progression was 4.4 (2.2-33.3) months, with a 2-year distant PFS rate of 38.9 % (20.1-57.3). Median OS time for patients was 23.1 (11.1-33.0) months. Of the 14 patients who underwent surgery, median survival was 32.3 (13.8-48.0) months compared with 13.3 (2.2-33.0) months in patients not undergoing surgery (p = 0.10). A margin-negative (R0) resection was achieved in 10 (71 %) of the surgeries. Radiation treatment modality (intensity-modulated radiation therapy, three-dimensional conformal radiotherapy, intraoperative radiation therapy) did not influence local or distant PFS or OS. CONCLUSION: Re-irradiation is a beneficial treatment modality for the management of locally recurrent, non-metastatic rectal cancer. It is associated with symptom improvement, low rates of toxicity, and similar benefits among radiation modalities.

BACKGROUND: Several reports suggest that the efficacy of adjuvant chemotherapy on survival diminishes over time for colon cancer; however, precise timing of its loss of benefit has not been established. OBJECTIVE: This study aimed to determine the relationship between time to adjuvant chemotherapy and survival and to identify a threshold for increased risk of mortality. DESIGN: This was a retrospective study. Multivariable Cox proportional hazard modeling with restricted cubic splines was used to evaluate the adjusted association between time to adjuvant chemotherapy and overall survival and to establish an optimal threshold for the initiation of therapy. SETTINGS: Data were collected from the National Cancer Data Base. PATIENTS: Adults who received adjuvant chemotherapy following resection of stage II to III colon cancers were selected. MAIN OUTCOME MEASURES: The primary outcome measured was overall survival. RESULTS: A total of 7794 patients were included. After adjusting for clinical, tumor, and treatment characteristics, our model determined a critical threshold of chemotherapy initiation at 44 days from surgery, after which there was an increase in the overall mortality. At a median follow-up of 61 months, the risk of mortality was increased in those who received adjuvant chemotherapy after 44 days from surgery (adjusted HR, 1.14; 95% CI, 1.05-1.24; p = 0.002), but not in those who received chemotherapy before 44 days from surgery (p = 0.11). Each additional week of delay was associated with a 7% decrease in survival (HR, 1.07; 95% CI, 1.04-1.10; p < 0.001). LIMITATIONS: This study was limited by selection bias and the inability to compare specific chemotherapy regimens. CONCLUSIONS: This study objectively determines the optimal timing of adjuvant chemotherapy for patients with resected colon cancer. Delay beyond 6 weeks is associated with compromised survival. These findings emphasize the importance of the timely initiation of therapy, and suggest that efforts to enhance recovery following surgery have the potential to improve survival by decreasing delay to adjuvant chemotherapy.

BACKGROUND: Controversy exists over whether resection of the primary tumor in stage IV colorectal cancer with inoperable metastases improves patient outcomes. OBJECTIVE: The purpose of this study was to evaluate whether resection of the primary tumor without metastasectomy in patients with stage IV colorectal cancer is associated with improved overall survival compared with patients undergoing chemotherapy and/or radiation therapy alone. DESIGN: This was a retrospective review of a multi-institutional dataset. SETTINGS: This study was conducted in all participating commission on cancer (CoC)-accredited facilities. PATIENTS: The 2003-2006 National Cancer Data Base was reviewed to identify patients with stage IV adenocarcinoma of the colon or rectum who underwent palliative treatment without curative intent, either in the form of surgical resection of the primary tumor without metastasectomy consisting of a colectomy or rectal resection with or without chemotherapy and/or radiation or chemotherapy and/or radiation alone. MAIN OUTCOME MEASURES: Groups were compared for baseline characteristics. Overall survival was compared using Kaplan-Meier analysis before and after propensity matching with a 1:1 nearest-neighbor algorithm. RESULTS: Of the 1446 patients included in the analysis, 231 (16%) underwent surgical resection of the primary tumor without metastasectomy. Surgical resection was associated with a significant survival benefit on unadjusted analysis (median survival, 9.2 vs. 7.6 months; p < 0.01). After propensity matching to adjust for nonrandom treatment selection, surgical resection continued to be associated with a significant survival benefit (median survival, 9.2 vs. 7.3 months; p < 0.01). LIMITATIONS: This study was limited by the potential for selection bias regarding which patients received surgical resection. There was also a lack of data regarding the indication for operation, specifically whether a patient was symptomatic or asymptomatic before resection. The inability to account for tumor size or grade among patients who did not receive surgical resection was another limitation. CONCLUSIONS: Surgical resection of the primary tumor without metastasectomy in patients with metastatic colorectal cancer is associated with improved survival as compared with chemotherapy/radiation therapy alone. Additional research is necessary to determine which patients may benefit from this intervention.

Symptomatic hemorrhoid disease is one of the most prevalent ailments associated with significant impact on quality of life. Management options for hemorrhoid disease are diverse, ranging from conservative measures to a variety of office and operating-room procedures. In this review, the authors will discuss the anatomy, pathophysiology, clinical presentation, and management of hemorrhoid disease.
RESUMO
OBJECTIVE: To determine the association between preoperative bowel preparation and 30-day outcomes after elective colorectal resection. METHODS: Patients from the 2012 Colectomy-Targeted American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database who underwent elective colorectal resection were included for analysis and assigned to 1 of 4 groups based on the type of preoperative preparation they received [combined mechanical and oral antibiotic preparation (OAP), mechanical preparation only, OAP only, or no preoperative bowel preparation]. The association between preoperative bowel preparation status and 30-day postoperative outcomes was assessed using multivariate regression analysis to adjust for a robust array of patient- and procedure-related factors. RESULTS: A total of 4999 patients were included for this study [1494 received (29.9%) combined mechanical and OAP, 2322 (46.5%) received mechanical preparation only, 91 (1.8%) received OAP only, and 1092 (21.8%) received no preoperative preparation]. Compared to patients receiving no preoperative preparation, patients who received combined preparation demonstrated a lower 30-day incidence of postoperative incisional surgical site infection (3.2% vs 9.0%, P < 0.001), anastomotic leakage (2.8% vs 5.7%, P = 0.001), and procedure-related hospital readmission (5.5% vs 8.0%, P = 0.03). The outcomes of patients who received either mechanical or OAP alone did not differ significantly from those who received no preparation. CONCLUSIONS: Combined bowel preparation with mechanical cleansing and oral antibiotics results in a significantly lower incidence of incisional surgical site infection, anastomotic leakage, and hospital readmission when compared to no preoperative bowel preparation.
