The Predictors of Complete Pathologic Response in Rectal Cancer during the Total Neoadjuvant Therapy Era: A Systematic Review.

The modern rectal cancer treatment paradigm offers additional opportunities for organ preservation, most notably via total neoadjuvant therapy (TNT) and consideration for a watch-and-wait (WW) surveillance-only approach. A major barrier to widespread implementation of a WW approach to rectal cancer is the potential discordance between a clinical complete response (cCR) and a pathologic complete response (pCR). In the pre-TNT era, the identification of predictors of pCR after neoadjuvant therapy had been previously studied. However, the last meta-analysis to assess the summative evidence on this important treatment decision point predates the acceptance and dissemination of TNT strategies. The purpose of this systematic review was to assess preoperative predictors of pCR after TNT to guide the ideal selection criteria for WW in the current era. An exhaustive literature review was performed and the electronic databases Embase, Ovid, MEDLINE, PubMed, and Cochrane were comprehensively searched up to 27 June 2023. Search terms and their combinations included "rectal neoplasms", "total neoadjuvant therapy", and "pathologic complete response". Only studies in English were included. Randomized clinical trials or prospective/retrospective cohort studies of patients with clinical stage 2 or 3 rectal adenocarcinoma who underwent at least 8 weeks of neoadjuvant chemotherapy in addition to chemoradiotherapy with pCR as a measured study outcome were included. In this systematic review, nine studies were reviewed for characteristics positively or negatively associated with pCR or tumor response after TNT. The results were qualitatively grouped into four categories: (1) biochemical factors; (2) clinical factors; (3) patient demographics; and (4) treatment sequence for TNT. The heterogeneity of studies precluded meta-analysis. The level of evidence was low to very low. There is minimal data to support any clinicopathologic factors that either have a negative or positive relationship to pCR and tumor response after TNT. Additional data from long-term trials using TNT is critical to better inform those considering WW approaches following a cCR.

Telehealth Availability for Cancer Care During the COVID-19 Pandemic: Cross-Sectional Study.

BACKGROUND: Telehealth was an important strategy for maintaining continuity of cancer care during the coronavirus pandemic and has continued to play a role in outpatient care; however, it is unknown whether services are equally available across cancer hospitals. OBJECTIVE: This study aimed to assess telehealth availability at cancer hospitals for new and established patients with common cancers to contextualize the impact of access barriers to technology on overall access to health care. METHODS: We conducted a national cross-sectional secret shopper study from June to November 2020 to assess telehealth availability at cancer hospitals for new and established patients with colorectal, breast, and skin (melanoma) cancer. We examined facility-level factors to determine predictors of telehealth availability. RESULTS: Of the 312 investigated facilities, 97.1% (n=303) provided telehealth services for at least 1 cancer site. Telehealth was less available to new compared to established patients (n=226, 72% vs n=301, 97.1%). The surveyed cancer hospitals more commonly offered telehealth visits for breast cancer care (n=266, 85%) and provided lower access to telehealth for skin (melanoma) cancer care (n=231, 74%). Most hospitals (n=163, 52%) offered telehealth for all 3 cancer types. Telehealth availability was weakly correlated across cancer types within a given facility for new (r=0.16, 95% CI 0.09-0.23) and established (r=0.14, 95% CI 0.08-0.21) patients. Telehealth was more commonly available for new patients at National Cancer Institute-designated facilities, medical school-affiliated facilities, and major teaching sites, with high total admissions and below-average timeliness of care. Telehealth availability for established patients was highest at Academic Comprehensive Cancer Programs, nongovernment and nonprofit facilities, medical school-affiliated facilities, Accountable Care Organizations, and facilities with a high number of total admissions. CONCLUSIONS: Despite an increase in telehealth services for patients with cancer during the COVID-19 pandemic, we identified differences in access across cancer hospitals, which may relate to measures of clinical volume, affiliation, and infrastructure.

More problems, more money: Identifying and predicting high-cost rescue after colorectal surgery.

Background: Successful rescue after elective surgery is associated with increased healthcare costs, but costs vary widely. Treating all rescue events the same may overlook targeted opportunities for improvement. The purpose of this study was to predict high-cost rescue after elective colorectal surgery. Methods: We identified adult patients in the National Inpatient Sample (2016-2021) who underwent elective colectomy or proctectomy. Rescued patients were defined as those who underwent additional major procedures. Three groups were stratified: 1) uneventful recovery; 2) Low-cost rescue; 3) High-cost rescue. Multivariable Poisson regression was used to identify preoperative clinical predictors of high-cost versus low-cost rescue. Results: We identified 448,590 elective surgeries, and rescued patients composed 4.8 %(21,635) of the total sample. The median increase in costs in rescued patients was $25,544(p < 0.001). Median total inpatient costs were $95,926 in the most expensive rescued versus $34,811 in the less expensive rescued versus $16,751 in the uneventfully discharged(p < 0.001). When comparing the secondary procedures between the less expensive and most expensive rescued groups, the most expensive had an increased proportion of reoperation (73.4 % versus 53.0 %,p < 0.001). When controlling for other factors and stratification by congestive heart failure due to an interaction effect, a reoperation was independently associated with high-cost rescue (RR with CHF = 3.29,95%CI:2.69-4.04; RR without CHF = 2.29,95%CI:1.97-2.67). Conclusions: High-cost rescue after colorectal surgery is associated with disproportionately greater healthcare utilization and reoperation. For cost-conscious care, preemptive strategies that reduce reoperation-related complications can be prioritized.

Management of Colonic Emergencies.

The etiology of colonic emergencies includes a wide-ranging and diverse set of pathologic conditions. Fortunately, for the surgeon treating a patient with one of these emergencies, the surgical management of these various causes is limited to choosing among proximal diversion, segmental colectomy with or without proximal diversion, or a total abdominal colectomy with end ileostomy (or rarely, an ileorectal anastomosis). The nuanced complexity in these situations usually revolves around the nonsurgical and/or endoscopic options and deciding when to proceed to the operating room.

Direct stick embolization of a rectal venous malformation via transanal minimally invasive surgery.

Rectal venous malformations (VMs) are rare clinical entities with variable patterns of presentation. Treatment requires unique, targeted strategies based on the symptoms, associated complications, and location, depth, and extent of the lesion. We present a rare case of a large, isolated rectal VM treated by direct stick embolization (DSE) using transanal minimally invasive surgery (TAMIS). A 49-year-old man had presented with a rectal mass incidentally detected on computed tomography urography. Magnetic resonance imaging and endoscopy revealed an isolated rectal VM. Elevated D-dimer levels concerning for localized intravascular coagulopathy warranted the use of prophylactic rivaroxaban. To avoid invasive surgery, DSE using TAMIS was performed successfully without complications. His postoperative recovery was uneventful, aside from a self-limiting and expected course of postembolization syndrome. To the best of our knowledge, this is the first reported case of TAMIS-assisted DSE of a colorectal VM. TAMIS shows promise for more widespread use in the minimally invasive, interventional management of colorectal vascular anomalies.

Idiopathic myointimal hyperplasia of the mesenteric veins: A systematic review and individual patient data regression analysis.

BACKGROUND AND AIM: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is an uncommon cause of colonic ischemia for which surgical treatment is typically curative. We describe clinical, radiologic, and endoscopic findings in IMHMV patients to provide clinicians with a framework for pre-surgical identification of this rare disease. METHODS: We performed a systematic review of seven databases for IMHMV cases and identified additional cases from Yale New Haven Hospital records. To identify features specifically associated with colonic ischemia due to IMHMV, we performed multivariate logistic regression analysis incorporating data from a large cohort of patients with biopsy-proven ischemic colitis. RESULTS: A total of 124 patients with IMHMV were identified (80% male, mean age 53 years, 56% Caucasian). Presenting symptoms were most commonly abdominal pain (86%) and diarrhea (68%). The most affected areas were the sigmoid colon (91%) and rectum (61%). Complications associated with diagnostic delay occurred in 29% of patients. Radiologic vascular abnormalities including non-opacification of the inferior mesenteric vein were observed in 35% of patients. Of the patients, 97% underwent curative surgical resection. Compared with non-IMHMV colonic ischemia, IMHMV was significantly associated with younger age, male sex, absence of rectal bleeding on presentation, rectal involvement, and mucosal ulcerations on endoscopy. CONCLUSION: IMHMV is a rare, underreported cause of colonic ischemia that predominantly involves the rectosigmoid. Our findings suggest younger age, rectal involvement, and absence of rectal bleeding as clinical features to help identify select patients presenting with colonic ischemia as having higher likelihood of IMHMV and therefore consideration of upfront surgical management.

So You Want to be a Program Director? Career Paths of Colon and Rectal Surgery Residency Program Directors.

BACKGROUND: The trajectory of colon and rectal surgery residency program director (PD) career paths has not been well described, leaving those who aspire for the position with minimal guidance. The goal of this study is to characterize their career paths in the United States. By understanding their experiences, the path to train and educate the next generation of colon and rectal surgeons as a PD will be better illuminated. STUDY DESIGN: This study was an anonymous, cross-sectional survey of all junior and senior colon and rectal surgery residency PDs in the United States during April and May of 2022. PDs were divided into junior and senior PDs. Results were compared using 2-sided independent t-tests and Kruskall-Wallis tests. RESULTS: Of 65 colon and rectal surgery PDs, 48% (31/65) completed the survey which encompassed demographics, leadership, education, research, and time utilization. Participants were primarily white and male, although increased female representation was identified among the junior PDs (50%). Junior PDs were also more likely to hold associate or assistant professor positions at time of appointment (p = 0.01) and a majority of all PDs (64%) previously or currently held a leadership position in a national or regional surgical association. When appointed, senior PDs reported increased teaching time. CONCLUSIONS: This multi-institutional analysis of colon and rectal surgery residency PDs identified a trend towards equal gender representation and diversity amongst upcoming junior PDs. All respondents were appointed to PD from within the institution. Other key experiences included previous leadership roles and associate or assistant professor positions at time of appointment. While it is impossible to create a single recommended template for every aspiring colon and rectal surgery educator to advance to a PD position, this study provides guideposts along that career path.

Do Cultures From Percutaneously Drained Intra-abdominal Abscesses Change Treatment? A Retrospective Review.

BACKGROUND: Routinely obtaining intraoperative cultures for abdominal infections is not a currently recommended evidence-based practice. Yet, cultures are frequently sent from these infections when they are managed by image-guided percutaneous drains. OBJECTIVE: This study aimed to determine the utility of cultures from percutaneously drained intra-abdominal abscesses. DESIGN: Retrospective medical record review. SETTING: Single university-affiliated institution. PATIENTS: Inpatients with an intra-abdominal abscess secondary to diverticulitis or appendicitis between 2013 and 2021 managed with image-guided percutaneous drain, excluding those with active chemotherapy, HIV, or solid organ transplant, were included in the study. MAIN OUTCOME MEASURES: Frequency culture data from percutaneous drains changed antimicrobial therapy. RESULTS: There were 221 patients who met the inclusion criteria. Of these, 56% were admitted for diverticulitis and 44% for appendicitis. Patients were 54% female and had a median age of 62 years (range, 18-93), and 14% were active smokers. The median length of hospitalization was 8 days (range, 1-78) and the median antibiotics course was 8 days (range, 1-22). Culture data from percutaneous drains altered antimicrobial therapy in 8% of patients (16/211). A culture was obtained from 95% of drains, with 78% of cultures with growth. Cultures grew multiple bacteria in 66% and mixed variety without speciation in 13%. The most common pathogen was the Bacteroides family at 33% of all bacteria. The most common empiric antibiotic regimens were ceftriaxone used in 33% of patients and metronidazole used in 40% of patients. Female sex ( p = 0.027) and presence of bacteria with any antibiotic resistance ( p < 0.01) were associated with higher likelihood of cultures influencing antimicrobial therapy. LIMITATIONS: Retrospective and single institution's microbiome. CONCLUSIONS: Microbiology data from image-guided percutaneous drains of abdominal abscesses altered antimicrobial therapy in 8% of patients, which is lower than reported in previously published literature on cultures obtained surgically. Given this low rate, similar to the recommendation regarding cultures obtained intraoperatively, routinely culturing material from drains placed in abdominal abscesses is not recommended.

De estos, el 56% ingresaron por diverticulitis y el 44% por apendicitis. El 54% de los pacientes eran mujeres, tenían una edad media de 62 años (18-93) y el 14% eran fumadores activos. La duración de hospitalización media fue de 8 días (rango, 1-78) y la mediana del curso de antibióticos fue de 8 días (rango, 1-22). Los datos de cultivo de drenajes percutáneos alteraron la terapia antimicrobiana en el 7% (16/221) de los pacientes. Se obtuvo cultivo del 95% de los drenajes, con un 79% de cultivos con crecimiento. Los cultivos produjeron múltiples bacterias en el 63% y variedad mixta sin especiación en el 13%. El patógeno más común fue la familia Bacteroides con un 33% de todas las bacterias. El régimen de antibiótico empírico más común fue ceftriaxona y metronidazol, utilizados en el 33% y el 40% de los pacientes, respectivamente. El sexo femenino ( p = 0,027) y la presencia de bacterias con alguna resistencia a los antibióticos ( p < 0,01) se asociaron con una mayor probabilidad de que los cultivos influyeran en la terapia antimicrobiana.LIMITACIONES:Microbioma retrospectivo y de una sola institución.CONCLUSIONES:Los datos microbiológicos de los drenajes percutáneos guiados por imágenes de los abscesos abdominales alteraron la terapia antimicrobiana en el 7% de los pacientes, que es inferior a la literatura publicada previamente sobre cultivos obtenidos quirúrgicamente. Dada esta baja tasa, similar a la recomendación sobre cultivos obtenidos intraoperatoriamente, no se recomienda el cultivo rutinario de material de drenajes colocados en abscesos abdominales.

How Far Is Too Far? Cost-Effectiveness Analysis of Regionalized Rectal Cancer Surgery.

BACKGROUND: Regionalized rectal cancer surgery may decrease postoperative and long-term cancer-related mortality. However, the regionalization of care may be an undue burden on patients. OBJECTIVE: This study aimed to assess the cost-effectiveness of regionalized rectal cancer surgery. DESIGN: Tree-based decision analysis. PATIENTS: Patients with stage II/III rectal cancer anatomically suitable for low anterior resection were included. SETTING: Rectal cancer surgery performed at a high-volume regional center rather than the closest hospital available. MAIN OUTCOME MEASURES: Incremental costs ($) and effectiveness (quality-adjusted life year) reflected a societal perspective and were time-discounted at 3%. Costs and benefits were combined to produce the incremental cost-effectiveness ratio ($ per quality-adjusted life year). Multivariable probabilistic sensitivity analysis modeled uncertainty in probabilities, costs, and effectiveness. RESULTS: Regionalized surgery economically dominated local surgery. Regionalized rectal cancer surgery was both less expensive on average ($50,406 versus $65,430 in present-day costs) and produced better long-term outcomes (10.36 versus 9.51 quality-adjusted life years). The total costs and inconvenience of traveling to a regional high-volume center would need to exceed $15,024 per patient to achieve economic breakeven alone or $112,476 per patient to satisfy conventional cost-effectiveness standards. These results were robust on sensitivity analysis and maintained in 94.6% of scenario testing. LIMITATIONS: Decision analysis models are limited to policy level rather than individualized decision-making. CONCLUSIONS: Regionalized rectal cancer surgery improves clinical outcomes and reduces total societal costs compared to local surgical care. Prescriptive measures and patient inducements may be needed to expand the role of regionalized surgery for rectal cancer. See Video Abstract at http://links.lww.com/DCR/C83 .

El análisis de sensibilidad probabilístico multivariable modeló la incertidumbre en las probabilidades, los costos y la efectividad.RESULTADOS:La cirugía regionalizada predominó económicamente la cirugía local. La cirugía de cáncer de recto regionalizado fue menos costosa en promedio ($50 406 versus $65 430 en costos actuales) y produjo mejores resultados a largo plazo (10,36 versus 9,51 años de vida ajustados por calidad). Los costos totales y la inconveniencia de viajar a un centro regional de alto volumen necesitarían superar los $15,024 por paciente para alcanzar el punto de equilibrio económico o $112,476 por paciente para satisfacer los estándares convencionales de rentabilidad. Estos resultados fueron sólidos en el análisis de sensibilidad y se mantuvieron en el 94,6% de las pruebas de escenarios.LIMITACIONES:Los modelos de análisis de decisiones se limitan al nivel de políticas en lugar de la toma de decisiones individualizada.CONCLUSIONES:La cirugía de cáncer de recto regionalizada mejora los resultados clínicos y reduce los costos sociales totales en comparación con la atención quirúrgica local. Es posible que se necesiten medidas prescriptivas e incentivos para los pacientes a fin de ampliar el papel de la cirugía regionalizada para el cáncer de recto.

Rare cases of colonic schwannomas.

Schwannomas of the gastrointestinal tract are rare spindle cell tumors that account for 2-6% of mesenchymal tumors. An elderly male was found to have a left colon mass on CT scan and colonoscopy with pathology of fibrotic tissue. A laparoscopic-assisted left hemi-colectomy with primary anastomosis was performed. Pathology demonstrated spindle cell neoplasm arranged in short fascicles that were strongly and diffusely positive for S100. An elderly female was found to have a submucosal lesion on surveillance colonoscopy in the proximal transverse colon. Biopsy with jumbo forceps revealed spindle cell neoplasm positive for S100. Patient underwent an uncomplicated limited non-oncologic segmental transverse colectomy. We report only the ninth case of left and sixth in the transverse colon described in the literature. As is true for other mesenchymal tumors, mucosal biopsy is usually inconclusive and deep biopsy or submucosal resection is required, making pre-operative surgical decision difficult.

Do You Get What You Pay For? The Relationship of Price and Quality in Hospital Provided Procedures.

INTRODUCTION: Starting in 2021, Centers for Medicare and Medicaid Services required hospitals to provide pricing information to allow consumers to compare prices. Patients perceived that the quality of these services also impacts decision-making. This study examines the relationship between procedure price and quality from the patients' perspective. MATERIALS AND METHODS: Unnegotiated prices of procedures were extracted from hospital websites. Hospital quality was defined as the U.S. News & World Report's score for the specialty performing the procedure. Regional differences in markets were corrected with the Wage Price Index. Spearman's correlations were used for analysis between price and quality. RESULTS: Overall, 67% (1225/1815) of hospitals had a pricing document. Compliance by procedure was poor with a low of 7% for Current Procedural Terminology (CPT) 93000 and a high of 27% for CPTs 93452 and 62323. Wide variability of prices for all procedures was noted. The smallest difference in price range listed was for CPT 45380 with a 32× difference between the minimum and maximum ($310-$10,023) with the first, second, and third quartiles being $1457, $2759, and $4276, respectively. The largest difference in price range was for CPT 55700 with a 5036× difference between the minimum and maximum ($9-$45,322) with the first, second, and third quartiles being $1638, $2971, and $5342, respectively. Correlation between price and quality was low, with the strongest being rho = 0.369 (P = 0.02) for CPT 93000. CONCLUSIONS: Compliance with price transparency was low with large variability in prices for the same procedure. There was no correlation between hospital price and quality. As currently implemented, poor compliance and wide price variability may limit patients' understanding of procedure costs.

Does Preoperative Calcium and Calcitriol Decrease Rates of Post-Thyroidectomy Hypocalcemia? A Randomized Clinical Trial.

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.

Has National Colorectal Cancer Awareness Month increased endoscopy screening rates and public interest in colorectal cancer?

BACKGROUND: National Colorectal Cancer Awareness Month occurs each March to promote awareness and screening for colorectal cancer. The effectiveness of this public health campaign is unknown. The aim of this study was to determine the impact of National Colorectal Cancer Awareness Month on rates of screening endoscopies and on public interest in colorectal cancer. METHODS: To examine the impact of National Colon Cancer Awareness Month on screening endoscopy rates, the National Endoscopy Database was retrospectively reviewed from 2002 through 2014. A time series of monthly number of colorectal cancer screening endoscopies per endoscopist in the data set was evaluated. To examine public interest in colorectal cancer, Google Trends data were collected on the monthly rates of terms related to colorectal cancer from January 2004 to July 2019. Impact of the month on screening endoscopies and public interest was assessed through an analysis of variance. Seasonality was tested for by how well a sinusoidal model fit the time series as opposed to a linear model utilizing a sum-of-squares F test. RESULTS: Review of National Endoscopy Database yielded 1,398,996 endoscopies, 94% were colonoscopies and 6% sigmoidoscopies, with 47% for colorectal cancer screening. Colorectal cancer screening endoscopy rates were not impacted by the month of the year, and these rates had no seasonality. However, Google searches related to colorectal cancer were significantly impacted by month of the year, specifically March, with significant seasonality observed in the data. CONCLUSIONS: National Colorectal Cancer Awareness Month is associated with an increased public interest in colorectal cancer based on user Google search trends. Yet, this has not translated into a demonstrable increase in the rates of screening. This presents an opportunity to capitalize on this increased public interest and harness this enthusiasm into increased screening.

Endoscopic Step Up: A Colon-Sparing Alternative to Colectomy to Improve Outcomes and Reduce Costs for Patients With Advanced Neoplastic Polyps.

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.

Should They Stay or Should They Go? The Utility of C-Reactive Protein in Predicting Readmission and Anastomotic Leak After Colorectal Resection.

BACKGROUND: Hospital readmission and anastomotic leak following colorectal resection have a negative impact on patients, surgeons, and the health care system. Novel markers of patients unlikely to experience these complications are of value in avoiding readmission. OBJECTIVE: This study aimed to determine the predictive value of C-reactive protein for readmission and anastomotic leak within 30 days following colorectal resection. DESIGN: This is a retrospective review of a prospectively compiled single-institution database. PATIENTS: From January 1, 2013, to July 20, 2017, consecutive patients undergoing elective colorectal resection with anastomosis without the presence of proximal intestinal stoma, who had C-reactive protein measured on postoperative day 3, were included. MAIN OUTCOME MEASURES: The primary outcome measured was the predictive value of C-reactive protein measured on postoperative day 3 for readmission or anastomotic leak within 30 days after colorectal resection. RESULTS: Of the 752 patients examined, 73 (10%) were readmitted within 30 days of surgery and 17 (2%) had an anastomotic leak. Mean C-reactive protein in patients who neither had an anastomotic leak nor were readmitted (127 ± 77 mg/L) was lower than for patients who were readmitted (157 ± 96 mg/L, p = 0.002) and lower than for patients who had an anastomotic leak (228 ± 123 mg/L, p = 0.0000002). The area under the receiver operating characteristic curve for the diagnostic accuracy of C-reactive protein for readmission was 0.59, with a cutoff value of 145 mg/L, generating a 93% negative predictive value. The area under the curve for the diagnostic accuracy of C-reactive protein for anastomotic leak was 0.76, with a cutoff value of 147 mg/L generating a 99% negative predictive value. LIMITATIONS: This study was limited by its retrospective design and because all patients were treated at a single center. CONCLUSIONS: Patients with a C-reactive protein below 145 mg/L on postoperative day 3 after colorectal resection have a low likelihood of readmission within 30 days, and a very low likelihood of anastomotic leak.

Is measurement of renal function necessary for all trauma patients before iodinated contrast administration?

PURPOSE: The purpose of this study was to identify factors at the time of presentation which could quickly exclude or identify renal dysfunction in blunt trauma patients, thus negating serum measurement of renal function prior to contrast-enhanced imaging and expediting care. METHODS: Patients, >18 years old, without renal failure, presenting after blunt trauma, with serum creatinine measured at presentation, were retrospectively studied at a single center. Variables recorded at presentation including vitals, mechanism, and past medical history were analyzed using multivariate regression analysis to identify independent predictors of abnormal renal function. RESULTS: From 2009 to 2015, a total of 1099 patients met the inclusion criteria. Of those, 75 (6.8%) had renal dysfunction at presentation. Patients with renal dysfunction had a mean age of 74.3 (SD 15.5) years old, and 57.3% were male. Multivariate analysis identified independent predictors of renal dysfunction at presentation as age ≥ 61 (p < 0.001), hypotension (p = 0.02), and diabetes (p = 0.02). The presence of a single identified factor had an 85% sensitivity for renal dysfunction and a 98.5% negative predictive value. CONCLUSIONS: Impaired renal function at presentation was infrequent in our trauma cohort. Trauma patients who were normotensive, under the age of 61, and without diabetes were unlikely to have impaired renal function at presentation. In the urgent setting of trauma, patients without these comorbidities are likely safe to forgo screening of renal function prior to contrast-enhanced imaging.
