RESUMO
OBJECTIVE: This large database study assessed whether extended pharmacologic prophylaxis for venous thromboembolism after colon cancer resection was associated with improved oncologic survival. BACKGROUND: Heparin-derivatives may confer an anti-neoplastic effect via a variety of mechanisms (e.g. inhibiting angiogenesis in the tumor microenvironment). Studies evaluating the oncologic benefit of heparin and its derivatives have been limited in post-surgical patients. Multiple society guidelines recommend consideration of 30-day treatment with low molecular weight heparin to reduce venous thromboembolism risk after abdominopelvic cancer surgery. However, utilization of extended prophylaxis remains low. METHODS: Surveillance, Epidemiology, and End Results-Medicare data were used to identify patients (age 65+) undergoing resection for non-metastatic colon cancer from 2016-2017. The primary outcomes were overall and cancer-specific survival. Log-rank testing and multivariable Cox regression compared survival in patients who received extended prophylaxis versus those that did not in an inverse propensity treatment weighted cohort. RESULTS: 20,102 patients were included in propensity-weighting and analyzed. 800 (3.98%) received extended pharmacologic prophylaxis. Overall and cancer-specific survival were significantly higher in patients receiving prophylaxis on log-rank tests (P=0.0017 overall, P=0.0200 cancer-specific). Multivariable Cox regression showed improved overall survival [aHR 0.66 (0.56-0.78)] and cancer-specific survival [aHR 0.56 (0.39-0.81)] with prophylaxis after controlling for patient, treatment, and hospital factors. CONCLUSIONS: Extended pharmacologic prophylaxis after colon cancer resection was independently associated with improved overall and cancer-specific survival. These results suggest a potential anti-neoplastic effect from heparin derivatives when used in the context of preventing post-surgical venous thromboembolism.
RESUMO
BACKGROUND: The optimal strategy for colonic polyps not amenable to traditional endoscopic polypectomy is unknown. Endoscopic step up is a promising strategy for definitive treatment. OBJECTIVE: The purpose of this study was to determine whether endoscopic step up leads to improved outcomes and decreased costs compared with planned colectomy for endoscopically unresectable colon polyps. DESIGN: This was a retrospective review of a prospective database. SETTING: The study was conducted at a tertiary referral center. PATIENTS: Consecutive patients referred for endoscopically unresectable colon polyps 15 to 50 mm in size were included. INTERVENTIONS: Patients underwent planned colectomy or endoscopic step up at the surgeon's discretion. Endoscopic step up began with diagnostic colonoscopy in the operating room. If the polyp was amenable to endoscopic removal, endoscopic mucosal resection or endoscopic submucosal dissection was performed with progression to combined endoscopic-laparoscopic surgery or laparoscopic colectomy, as indicated. MAIN OUTCOME MEASURES: The primary outcome was 30-day adverse events. We also examined length of stay, hospital charges, insurer payments, and polyp recurrence. RESULTS: A total of 52 patients underwent planned colectomy (48 laparoscopic), and 38 underwent endoscopic step up (28 endoscopic mucosal resection, 2 endoscopic submucosal dissection, 6 combined endoscopic-laparoscopic surgery, and 2 colectomy). Compared with planned colectomy, endoscopic step-up patients had fewer complications (13% vs 33%; p = 0.03) and shorter length of stay (median, 0 vs 4 d; p < 0.001). There was 1 readmission in the endoscopic step-up group and 5 in the planned colectomy group. Endoscopic step-up patients had lower hospital costs ($4790 vs $13,004; p < 0.001) and insurer payments ($2431 vs $19,951; p < 0.001). One-year polyp recurrence-free survival was 84% (95% CI, 67%-93%) in endoscopic step-up patients. All of the recurrences were benign, <1 cm, and managed endoscopically. LIMITATIONS: The study was limited by its nonrandomized design and short follow-up. CONCLUSIONS: An endoscopic step-up approach to colon polyps is associated with less morbidity, decreased healthcare costs, and colon preservation in 95% of patients. Additional studies are needed to evaluate long-term quality of life and polyp recurrence in this group. See Video Abstract at http://links.lww.com/DCR/B188. ENDOSCOPIC STEP UP: UNA ALTERNATIVA A COLECTOMíA PARA PRESERVACIóN DE COLON CON LOS PROPóSITOS DE MEJORAR RESULTADOS Y REDUCIR COSTOS EN PACIENTES CON PóLIPOS NEOPLáSICOS AVANZADOS: Se desconoce la estrategia óptima para los pólipos de colon no susceptibles a la polipectomia endoscópica tradicional. Endoscopic Step Up es una estrategia prometedora para el tratamiento definitivo.Determinar si Endoscopic Step Up produce mejores resultados y menores costos en comparación con la colectomía programada para pólipos de colon endoscópicamente no resecables.Revisión retrospectiva de una base de datos prospectiva.Centro de referencia de tercer nivel.Pacientes consecutivos remitidos para pólipos de colon endoscópicamente irresecables de tamaño 15-50 mm.Los pacientes se sometieron a colectomía programada o Endoscópico Step Up a discreción del cirujano. Endoscopic Step Up comenzó con una colonoscopia diagnóstica en el quirófano. Si el pólipo era susceptible de extirpación endoscópica, la resección endoscópica de la mucosa o la disección submucosa endoscópica se realizaba con progresión a cirugía endoscópica-laparoscópica combinada o colectomía laparoscópica, según a cosnideraciones clínicas en el transoperatorio.El resultado primario fue los eventos adversos a 30 días. Duración de la estadía hospitalaria, los cargos hospitalarios, los pagos de las aseguradoras y la recurrencia de pólipos también fueron examinados.Un total de 52 pacientes se sometieron a colectomía programada (48 laparoscópicas) y 38 se sometieron a Endoscopic Step Up (28 resección endoscópica de la mucosa, 2 disección submucosa endoscópica, 6 cirugía endoscópica-laparoscópica combinada y 2 colectomía). En comparación con la colectomía programada los pacientes endoscópicos Step Up tuvieron menos complicaciones (13% versus 33%, p = 0.03) y una estadía hospitalaria más corta (mediana 0 versus 4 días, p <0.001). Hubo 1 reingreso hospitalario en el grupo Endoscopic Step Up y 5 en el grupo de colectomía programada. Los pacientes endoscópicos Step Up tuvieron costos hospitalarios más bajos ($ 4,790 versus $ 13,004, p <0,001) y pagos de la aseguradora ($ 2,431 versus $ 19,951, p <0,001). La supervivencia libre de recurrencia de pólipos a un año fue del 84% (IC 95% 67-93) en pacientes endoscópicos Step Up. Todas las recurrencias fueron benignas, <1 cm, y manejadas endoscópicamente.Diseño no aleatorizado y seguimiento corto.El abordaje endoscópico Step Up para pólipos de colon se asocia con menos morbilidad, disminución de los costos de atención médica y preservación del colon en el 95% de los pacientes. Se ocupan más estudios para evaluar la calidad de vida a largo plazo y la recurrencia de pólipos en este grupo. Consulte Video Resumen en http://links.lww.com/DCR/B188.

INTRODUCTION: Currently, no standard workflow exists for managing patients with pathogenic variants that put them at higher risk for hereditary cancers. Therefore, follow-up care for individuals with pathogenic variants is logistically challenging and results in poor guideline adherence. To address this challenge, authors created clinical management strategies for individuals identified at high risk for hereditary cancers. METHODS: An implementation mapping approach was used to develop and evaluate the establishment of a Hereditary Cancer Clinic at the Medical University of South Carolina throughout in 2022. This approach consisted of 5 steps: conduct a needs assessment, identify objectives, select implementation strategies, produce implementation protocols, and develop an evaluation plan. The needs assessment consisted of qualitative interviews with patients (n=11), specialists (n=9), and members of the implementation team (n=4). Interviews were coded using the Consolidated Framework for Implementation Research to identify barriers and facilitators to establishment of the Hereditary Cancer Clinic. Objectives were identified, and then the team selected implementation strategies and produced implementation protocols to address concerns identified during the needs assessment. Authors conducted a second round of patient interviews to assess patient education materials. RESULTS: The research team developed a long-term evaluation plan to guide future assessment of implementation, service, and clinical/patient outcomes. CONCLUSIONS: This approach provides the opportunity for real-time enhancements and impact, with strategies for care specialists, patients, and implementation teams. Findings support ongoing efforts to improve patient management and outcomes while providing an opportunity for long-term evaluation of implementation strategies and guidelines for patients at high risk for hereditary cancers.

BACKGROUND: Horseshoe fistula is a challenging benign anorectal condition to treat. The aim of this study was to assess the utilization and success of different definitive fistula repair techniques in the treatment of horseshoe fistula. METHODS: This was a retrospective case series which included all patients who were treated for horseshoe fistula from 2006 to 2019 at a single, tertiary care center and whom had at least one follow-up visit. Patients were excluded if < 18 years of age or carried a diagnosis of Crohn's disease. Patients were assessed for fistula recurrence and incontinence. RESULTS: Sixty-eight patients were identified. On average, they were 47 years old, 63% male, and 18% current smokers. Seventy-nine percent required seton during their treatment course. Of the 8 first attempts at fistula repair, the types of repair included flap (15%), LIFT (35%), fistulotomy (31%), plug (12%), and fistulotomy and immediate reconstruction (1%). Recurrence for these procedures was as follows: flap 30%, LIFT 21%, fistulotomy 14%, plug 88%, and fistulotomy and immediate reconstruction 0%. Twelve patients who recurred underwent 17 additional procedures to attempt to cure their fistula. Overall, of those who underwent any attempt at definitive repair, 82% of patients were cured of their fistula, 12% had a chronic seton, and 6% had a chronic fistula. Thirteen percent of those who were cured had incontinence. The mean follow-up time was 1.1 years. Patients required a median of 3 procedures (range 1-11). CONCLUSION: Horseshoe fistula remains a complex anorectal condition. Successful repair can be performed in > 80% of patients. However, repair can often require multiple surgical procedures.

BACKGROUND: Postoperative hypocalcemia is the most common complication after thyroidectomy. Postoperative supplementation with calcium and calcitriol reduces its occurrence; however, prophylactic preoperative supplementation has not been studied systematically. The primary objective of this study was to determine whether pre- and postoperative calcium and calcitriol supplementation reduces postoperative hypocalcemia after total thyroidectomy compared with postoperative supplementation alone. STUDY DESIGN: We conducted a single-institution prospective randomized trial enrolling 82 patients undergoing total thyroidectomy from July 2017 through May 2019. Those undergoing partial thyroidectomy or concurrent planned parathyroidectomy were excluded. The intervention group started calcitriol 0.25 µg po bid and calcium carbonate 1,500 mg po tid 5 days preoperatively and continued postoperatively. The control group started these medications postoperatively. The primary end point was clinical or biochemical hypocalcemia. Secondary outcomes were postoperative calcium levels, need for intervention, length of stay, and readmission. RESULTS: Thirty-eight patients were randomized to the intervention group and 44 to the control group. There were 12 episodes of hypocalcemia; 5 (13.2%) in the intervention and 7 (15.9%) in the control group (p = 0.76). No differences were found in secondary outcomes; including postoperative calcium levels at each measured time point, need for intervention (n = 10 [26.3%], n = 15 [34.1%]; p = 0.48), length of stay (mean [SD] 32.3 [15.6] hours, 30.7 [10.5] hours; p = 0.6), or readmissions (n = 0 [0.0%], n = 3 [6.8%]; p = 0.24). CONCLUSIONS: Starting supplementation with calcium and calcitriol preoperatively does not reduce postoperative hypocalcemia compared with postoperative supplementation alone after total thyroidectomy. These findings do not support the practice of routine calcium and calcitriol supplementation before total thyroidectomy.

OBJECTIVE: To identify strategies and barriers to career progression in early-career colorectal surgeons. DESIGN: Qualitative research study performed via semi-structured interviews with early-career, board-certified colon, and rectal surgeons. Responses were analyzed, coded, and categorized to understand strategies towards career progression, perceived barriers to career progression, beliefs about case mix, and referral patterns. SETTING: Interviews conducted in person and via telephone across the United States and Canada. PARTICIPANTS: Early-career board-certified colorectal surgeons RESULTS: Twenty-two board-certified colorectal surgeons currently employed in 14 states and 1 foreign country were interviewed. Fourty-five percent were female. Their current practice environment was described as academic (77%), private practice (18%), or military (5%). Seventy-seven percent of surgeons were satisfied with their career progression. Seventy-two percent were satisfied with the case volume. Seventy-two percent were satisfied with their case mix. When asked about strategies for career progression, surgeons made 77 comments focused on three main themes: optimization of their job search, optimization of relationships while on the job, and efforts to augment individual achievement. When asked about barriers to career advancement, surgeons most frequently commented on a lack of time and a lack of mentors. When asked about case mix, 63% of surgeons felt that they had no control over it. They were evenly divided between believing that a broad case mix or a niche specialized case mix was more instrumental for career progression. CONCLUSIONS: Early-career colorectal surgeons were mostly satisfied with their career progression, volume, and case mix. In discussing their careers, many have developed a number of strategies focused on growth as an individual as well as relationship building. They also identified a number of barriers including lack of time and lack of mentorship. Early-career surgeons may be able to utilize these strategies and anticipate barriers prior to starting their first job, leading to greater likelihood of career satisfaction.
