Modern Trends in Surgical Site Infection Rates for Colorectal Surgery: A National Surgical Quality Improvement Project Study 2013-2020.

BACKGROUND: Few studies have investigated trends in global surgical site infection rates in colorectal surgery in the past decade. OBJECTIVE: This study seeks to describe changes in rates of different surgical site infections from 2013 to 2020, identify risk factors for surgical site infection occurrence, and evaluate the association of minimally invasive surgery and infection rates in colorectal resections. DESIGN: A retrospective analysis of the National Surgical Quality Improvement Program database 2013-2020 identifying patients undergoing open or laparoscopic colorectal resections by procedure codes was performed. Patient demographic information, comorbidities, procedures, and complications data were obtained. Univariable and multivariable logistic regression analyses were performed. SETTING: This was a retrospective study. PATIENTS: A total of 279,730 patients received colorectal resections from 2013 to 2020. MAIN OUTCOME MEASURES: The primary outcome measure was the rate of surgical site infection, divided into superficial, deep incisional, and organ space infections. RESULTS: There was a significant decrease in rates of superficial infections ( p < 0.01) and deep incisional infections ( p < 0.01) from 5.9% in 2013 to 3.3% in 2020 and from 1.4% in 2013 to 0.6% in 2020, respectively, but a rise in organ space infections ( p < 0.01) from 5.2% in 2013 to 7.1% in 2020. Minimally invasive techniques were associated with decreased odds of all surgical site infections compared to open techniques ( p < 0.01) in multivariate analysis, and adoption of minimally invasive techniques increased from 59% in 2013 to 66% in 2020. LIMITATIONS: The study is limited by its retrospective nature and variables available for analysis. CONCLUSIONS: Superficial and deep incisional infection rates have significantly decreased, likely secondary to improved adoption of minimally invasive techniques and infection prevention bundles. Organ space infection rates continue to increase. Additional research is warranted to clarify current recommendations for mechanical bowel preparation and oral antibiotic use as well as to study novel interventions to decrease postoperative infection occurrence.

TENDENCIAS MODERNAS EN LAS TASAS DE INFECCIN DEL SITIO QUIRRGICO PARA CIRUGA COLORRECTAL UN ESTUDIO DEL PROYECTO NACIONAL DE MEJORA DE LA CALIDAD QUIRRGICA: ANTECEDENTES:Hay pocos estudios que investiguen las tendencias en las tasas globales de infección del sitio quirúrgico en cirugía colorrectal en la última década.OBJETIVO:Este estudio busca describir cambios en las tasas de diferentes infecciones del sitio quirúrgico entre 2013 y 2020, identificar factores de riesgo para la aparición de ISQ y evaluar la asociación de la cirugía mínimamente invasiva y las tasas de infección en resecciones colorrectales.DISEÑO:Se realizó un análisis retrospectivo de la base de datos del Programa Nacional de Mejora de la Calidad Quirúrgica 2013-2020 que identifica a los pacientes sometidos a resecciones colorrectales abiertas o laparoscópicas mediante códigos de procedimiento. Se obtuvo información demográfica de los pacientes, comorbilidades, procedimientos y datos de complicaciones. Se realizó regresión logística univariable y multivariable.AJUSTE:Este fue un estudio retrospectivo.PACIENTES:Un total de 279,730 pacientes recibieron resección colorrectal entre 2013 y 2020.PRINCIPALES MEDIDAS DE RESULTADO:La medida de resultado primaria fue la tasa de infección del sitio quirúrgico, dividida en infecciones superficiales, incisionales profundas y del espacio de órganos.RESULTADOS:Hubo una disminución significativa en las tasas de infecciones superficiales (p < 0,01) e infecciones incisionales profundas ( p < 0,01) del 5,9% en 2013 al 3,3% en 2020 y del 1,4% en 2013 al 0,6% en 2020, respectivamente. pero un aumento en las infecciones del espacio de los órganos ( p < 0,01) del 5,2 % en 2013 al 7,1 % en 2020. El uso de técnicas mínimamente invasivas se asoció con una disminución de las probabilidades de todas las infecciones del sitio quirúrgico en comparación con las técnicas abiertas ( p < 0,01) en el análisis multivariado y la adopción de técnicas mínimamente invasivas aumentó del 59% en 2013 al 66% en 2020.LIMITACIONES:El estudio está limitado por la naturaleza retrospectiva y las variables disponibles para el análisis.CONCLUSIONES:Las tasas de infección superficial y profunda han disminuido significativamente, probablemente debido a una mejor adopción de técnicas mínimamente invasivas y esquemas de prevención de infecciones. Las tasas de infección del espacio de los órganos continúan aumentando. Se justifica realizar investigaciones adicionales para aclarar las recomendaciones actuales para la preparación intestinal mecánica y el uso de antibióticos orales, así como para estudiar intervenciones novedosas para disminuir la aparición de infecciones posoperatorias.

Clinically actionable findings on surveillance EGD in asymptomatic patients with Lynch syndrome.

BACKGROUND AND AIMS: Lynch syndrome (LS) predisposes patients to multiple cancers including of the gastric and small bowel. Data supporting EGD surveillance in LS are limited. Our aim is to describe upper GI (UGI) findings in asymptomatic LS patients undergoing EGD surveillance within a hereditary colorectal cancer registry. METHODS: Asymptomatic patients with LS who underwent ≥1 surveillance EGD were included. Demographics, genotype, and EGD findings were reviewed. The frequency of clinically actionable findings including neoplasia (cancer, adenomas), Barrett's esophagus (BE), Helicobacter pylori, and hyperplastic polyps >5 mm were assessed. RESULTS: Three hundred twenty-three patients underwent 717 EGDs starting at a median age of 49.5 years. On average, each patient had 2 EGDs with an interval of 2.3 years between examinations. Clinically actionable findings were identified in 57 patients (17.6%). On baseline EGD 27.7% of findings were identified, with the remainder on surveillance EGD over an average of 3.5 years. Five asymptomatic patients (1.5%) had an UGI cancer detected during surveillance, all at early stage, including 1 patient each with BE-related esophageal adenocarcinoma, gastric neuroendocrine tumor, and gastric adenocarcinoma and 2 patients with duodenal adenocarcinoma. Two cancers were found on baseline EGD and 3 on follow-up EGD. CONCLUSIONS: Clinically actionable findings were found in approximately 1 in 6 asymptomatic patients with LS undergoing EGD surveillance. Five patients (1.5%) were diagnosed with cancer, all detected at an early stage. These data suggest that both baseline and follow-up EGD surveillance are effective in detecting early-stage UGI cancers in asymptomatic patients with LS.

Evaluation of Urinalysis-Based Screening for Urothelial Carcinoma in Patients With Lynch Syndrome.

BACKGROUND: Approximately 5% to 10% of patients with Lynch syndrome develop urothelial carcinoma. Current screening recommendations vary and are based on expert opinion. Practices need to be evaluated for clinical effectiveness. Our program utilizes urinalysis as a screening test, followed by additional evaluation of microscopic hematuria. OBJECTIVE: This study aimed to determine the clinical utility of a urinalysis-based screening approach for urothelial cancers in patients with Lynch syndrome. DESIGN: This is a retrospective review of a prospectively maintained cohort. SETTING: Patients with Lynch syndrome were managed at a tertiary referral center. PATIENTS: All patients with a Lynch syndrome diagnosis who had a screening urinalysis done as part of our institutional screening protocol (N = 204) were included. MAIN OUTCOME MEASURES: A single-institution hereditary colorectal cancer syndrome registry was queried for patients with Lynch syndrome who had been screened for urothelial carcinomas by urinalysis. Demographics, genotype, family history of urothelial carcinoma, urinalysis results, and subsequent screenings and final diagnosis were gathered for patients between 2008 and 2017. RESULTS: Two hundred four asymptomatic patients underwent screening by urinalysis. Nineteen patients (9.3%) had microscopic hematuria and were further evaluated with urine cytology, imaging, cystoscopy, and/or Urology consultation. None of the 19 patients with microscopic hematuria had urothelial carcinoma. During the same study period, 5 of 204 (2.4%) patients with Lynch syndrome were diagnosed with urothelial cancer, and all presented with symptoms between screening intervals. LIMITATIONS: This is a retrospective study, and not all patients underwent the same secondary evaluation. CONCLUSIONS: No urothelial carcinomas were detected by screening urinalysis in our cohort of asymptomatic patients with Lynch syndrome. False-positive testing led to extensive, mostly uninformative, workups. If urothelial cancer screening is to continue, more effective screening approaches need to be identified.

Diecinueve pacientes (9,3%) tenían hematuria microscópica y fueron investigados más a fondo con citología de orina, imágenes, cistoscopia y / o consulta de urología. Ninguno de los 19 pacientes con hematuria microscópica tenían carcinoma urotelial. Durante el mismo período de estudio, 5 de 204 (2,4%) pacientes con síndrome de Lynch fueron diagnosticados con cáncer urotelial y todos presentaron presentando síntomas entre los intervalos de detección.LIMITACIONES:Estudio retrospectivo y no todos los pacientes sometidos a la misma evaluación secundaria.CONCLUSIONES:No se detectaron carcinomas uroteliales mediante análisis de orina de detección en nuestra cohorte de pacientes asintomáticos con síndrome de Lynch. Las pruebas de falsos positivos. Condujeron a estudios exhaustivos y en su mayoría poco informativos. Si se desea continuar con la detección del cáncer de urotelio, es necesario identificar enfoques de detección más efectivos. Consulte Video Resumen en http://links.lww.com/DCR/B702.

Colostomy as a definitive treatment in an ALS patient with acute colonic Pseudo-obstruction refractory to medical management, a case report.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease, and ALS patients may experience disturbed gastrointestinal motility often resulting in acute colonic pseudo-obstruction (ACPO). There is currently a paucity in the literature to guide the treatment of patients with both ALS and ACPO. CASE PRESENTATION: Here we describe a 39-year-old male patient with advanced ALS who developed ACPO. His condition was refractory to both medical and procedural managements including polyethylene glycol, senna, and docusate suppository, metoclopramide, linaclotide, erythromycin, prucalopride, neostigmine, and repeated colonoscopies. He ultimately underwent successful colostomy for palliation. Here we report the peri-operative multidisciplinary approach taken with this case, the surgical procedures, the potential risks, and the outcome. CONCLUSION: The patient is delighted with the result and requested publication of this case to raise awareness of constipation in ALS patients and promote the consideration of colostomy as a treatment option for patients with ileus resistant to conservative management. Ultimately, a multidisciplinary team approach is required to properly assess the risks and benefits to achieve good clinical outcomes.

Male gender, smoking, younger age, and preoperative pain found to increase postoperative opioid requirements in 592 elective colorectal resections.

PURPOSE: With increased awareness of the opioid epidemic, understanding contributing factors to postoperative opioid use is important. The purpose of this study was to evaluate patient and perioperative factors that contribute to postoperative opioid use after colorectal resections and their relation to pre-existing pain conditions and psychiatric diagnoses. METHODS: A retrospective review was conducted identifying adult patients who underwent elective colorectal resection at a single tertiary center between 2015 and 2018. Patient demographics, preoperative factors, surgical approach, and perioperative pain management were evaluated to determine standard conversion morphine milligram equivalents required for postoperative days 0 to 3 and total hospital stay. RESULTS: Five hundred and ninety-two patients: 46% male, median age 58 years undergoing colorectal resections for indications including cancer, inflammatory bowel disease, and diverticulitis were identified. Less opioid use was found to be associated with female gender (ß = - 42), patients who received perioperative lidocaine infusion (ß = - 30), and older adults (equivalents/year) (ß = - 4, all p < 0.01). Preoperative opioid use, preoperative abdominal pain, epidural use, and smoking were all independently associated with increased postoperative opioid requirements. CONCLUSIONS: In this study of patients undergoing elective colorectal resection, factors that were associated with higher perioperative opioid use included male gender, smoking, younger age, preoperative opioid use, preoperative abdominal pain, and epidural use. Perioperative administration of lidocaine was associated with decreased opioid requirements. Understanding risk factors and stratifying postoperative pain regimens may aid in improved pain control and decrease long-term dependency.

Impact of KRAS status on tumor response and survival after neoadjuvant treatment of locally advanced rectal cancer.

BACKGROUND: Mutation of the KRAS oncogene (mKRAS) in colorectal cancer has been associated with aggressive tumor biology, resistance to epidermal growth factor inhibitors, and decreased overall survival (OS). The aim of the current study was to analyze the association of mKRAS with pathologic complete response (pCR) and neoadjuvant rectal (NAR) score, and its impact on the survival of patients with locally advanced rectal cancer who were managed with multimodality therapy. METHODS: The National Cancer Database was queried for stage II-III rectal cancer patients with a known KRAS status who underwent neoadjuvant chemoradiation therapy (nCRT) and proctectomy between 2004 and 2015. RESULTS: In total, 1886 patients were identified; 12% had pCR and 36% had mKRAS. Patients with mKRAS were more likely to have advanced pathologic T stage, tumor deposits, perineural invasion, and elevated carcinoembryonic antigen levels (all p ≤ .05). After adjustment for available confounders, mKRAS status was not associated with pCR or NAR score. In multivariable analysis, patients with pCR and lower NAR score had better OS, whereas mKRAS was independently associated with a worse prognosis. CONCLUSION: In this cohort of locally advanced rectal cancer patients who underwent proctectomy after nCRT, mKRAS was not associated with lower pCR rates or NAR scores; however, these patients experienced worse survival.

Anastomotic Technique-How to Optimize Success and Minimize Leak Rates.

Determining when to perform a bowel anastomosis and whether to divert can be difficult, as an anastomosis made in a high-risk patient or setting has potential for disastrous consequences. While the surgeon has limited control over patient-specific characteristics, the surgeon can control the technique used for creating anastomoses. Protecting and ensuring a vigorous blood supply is fundamental, as is mobilizing bowel completely, and employing adjunctive techniques to attain reach without tension. There are numerous ways to create anastomoses, with variations on the segment and configuration of bowel used, as well as the materials used and surgical approach. Despite numerous studies on the optimal techniques for anastomoses, no one method has prevailed. Without clear evidence on the best anastomotic technique, surgeons should focus on adhering to good technique and being comfortable with several configurations for a variety of conditions.

Positive circumferential resection margins following locally advanced colon cancer surgery: Risk factors and survival impact.

BACKGROUND: While the prognostic implications of positive circumferential resection margins (CRM) have been established for rectal cancer, its significance in colon cancer has not been well defined. The aim of the current study was to determine national rates for positive CRM in locally advanced colon cancer, associated factors, and survival impact. METHODS: The National Cancer Database was queried to identify patients with stage II-III adenocarcinoma of the colon (2004-2015). RESULTS: Positive CRM was identified in 9% of stage II and 12% of stage III patients. Factors associated with negative CRM included surgery in a high-volume facility, adequate lymph-node harvest, and negative distal/proximal margins. No difference in CRM rates was observed between surgical approaches, although having a positive CRM was significantly associated with higher conversion rates. Positive CRM was associated with significantly lower overall survival on both univariate and multivariable analysis. CONCLUSIONS: Positive CRM rates exceeded 10% nationally and have an adverse impact on survival. While several tumor characteristics were identified as independent risk factors, oncologic resections and surgery at high-volume centers were associated with lower rates of positive CRM. These findings emphasize the need for process improvement initiatives targeting modifiable factors, including adoption of appropriate oncologic techniques, standardized pathology reporting, and potential neoadjuvant strategies.

Guideline-Recommended Chemoradiation for Patients With Rectal Cancer at Large Hospitals: A Trend in the Right Direction.

BACKGROUND: Many patients with rectal cancer are treated at small, low-volume hospitals despite evidence that better outcomes are associated with larger, high-volume hospitals. OBJECTIVES: This study aims to examine trends of patients with rectal cancer who are receiving care at large hospitals, to determine the patient characteristics associated with treatment at large hospitals, and to assess the relationships between treatment at large hospitals and guideline-recommended therapy. DESIGN: This study was a retrospective cohort analysis to assess trends in rectal cancer treatment. SETTINGS: Data from the National Cancer Institute's Surveillance, Epidemiology, and End Results Patterns of Care studies were used. PATIENTS: The study population consisted of adults diagnosed with stages II/III rectal cancer in 1990/1991, 1995, 2000, 2005, 2010, and 2015. MAIN OUTCOME MEASURES: The primary outcome was treatment at large hospitals (≥500 beds). The receipt of guideline-recommended preoperative chemoradiation therapy and postoperative chemotherapy was assessed for patients diagnosed in 2005+. RESULTS: Two thousand two hundred thirty-one patients were included. The proportion treated at large hospitals increased from 19% in 1990/1991 to 27% in 2015 (ptrend < 0.0001). Black race was associated with treatment at large hospitals (vs white) (OR, 1.73; 95% CI, 1.30-2.31), as was being 55 to 64 years of age (vs 75+), and diagnosis in 2015 (vs 1990/1991). Treatment in large hospitals was associated with twice the odds of preoperative chemoradiation, as well as younger age and diagnosis in 2010 or 2015 (vs 2005). LIMITATIONS: The study did not account for the change in the number of large hospitals over time. CONCLUSIONS: Results suggest that patients with rectal cancer are increasingly being treated in large hospitals where they receive more guideline-recommended therapy. Although this trend is promising, patients receiving care at larger, higher-volume facilities are still the minority. Initiatives increasing patient and provider awareness of benefits of specialized care, as well as increasing referrals to large centers may improve the use of recommended treatment and ultimately improve outcomes.

QUIMIORRADIACIÓN RECOMENDADA EN GUÍAS PARA PACIENTES CON CÁNCER RECTAL EN HOSPITALES DE GRAN TAMAÑO: UNA TENDENCIA EN LA DIRECCIÓN CORRECTA: Muchos pacientes con cáncer rectal se tratan en hospitales pequeños y de bajo volumen a pesar de evidencia de que los mejores resultados se asocian con hospitales más grandes y de gran volumen. OBJETIVOS: Examinar las tendencias en los pacientes con cáncer rectal que reciben atención en hospitales de gran tamaño, determinar las características de los pacientes asociadas con el tratamiento en hospitales grandes y evaluar la relación entre el tratamiento en hospitales grandes y la terapia recomendada en guías. DISEÑO:: Este estudio fue un análisis de cohorte retrospectivo para evaluar las tendencias en el tratamiento del cáncer de recto. ESCENARIO: Se utilizaron datos de los estudios del programa Patrones de Atención, Vigilancia, Epidemiología y Resultados Finales (SEER) del Instituto Nacional de Cáncer (NIH). PACIENTES: La población de estudio consistió en adultos diagnosticados con cáncer rectal en estadio II / III en 1990/1991, 1995, 2000, 2005, 2010 y 2015. PRINCIPALES MEDIDAS DE RESULTADO: El resultado primario fue el tratamiento en hospitales grandes (≥500 camas). La recepción de quimiorradiación preoperatoria recomendada según las guías y la quimioterapia posoperatoria se evaluaron para los pacientes diagnosticados en 2005 y posteriormente. RESULTADOS: Se incluyeron 2,231 pacientes. La proporción tratada en los hospitales grandes aumentó del 19% en 1990/1991 al 27% en 2015 (ptrend < 0.0001). La raza afroamericana se asoció con el tratamiento en hospitales grandes (vs. blanca) (OR, 1.73; IC 95%, 1.30-2.31), al igual que 55-64 años de edad (vs ≥75) y diagnóstico en 2015 (vs 1990/1991). El tratamiento en los hospitales grandes se asoció con el doble de probabilidad de quimiorradiación preoperatoria, así como con una edad más temprana y diagnóstico en 2010 o 2015 (vs 2005). LIMITACIONES: El estudio no tomó en cuenta el cambio en el número de hospitales grandes a lo largo del tiempo. CONCLUSIONES: Los resultados sugieren que los pacientes con cáncer rectal reciben cada vez más tratamiento en hospitales grandes donde reciben terapia recomendada por las guías mas frecuentemente. Aunque esta tendencia es prometedora, los pacientes que reciben atención en hospitales más grandes y de mayor volumen siguen siendo una minoría. Las iniciativas que aumenten la concientización del paciente y del proveedor de servicios médicos sobre los beneficios de la atención especializada, así como el aumento de las referencias a centros grandes podrían mejorar el uso del tratamiento recomendado y, en última instancia, mejorar los resultados.

Optimizing Treatment for Rectal Prolapse.

Rectal prolapse is associated with debilitating symptoms and leads to both functional impairment and anatomic distortion. Symptoms include rectal bulge, mucous drainage, bleeding, incontinence, constipation, tenesmus, as well as discomfort, pressure, and pain. The only cure is surgical. The optimal surgical repair is not yet defined though laparoscopic rectopexy with mesh is emerging as a more durable approach. The chosen approach should be individually tailored, taking into account factors such as presence of pelvic floor defects and coexistence of vaginal prolapse, severe constipation, surgical fitness, and whether the patient has had a previous prolapse procedure. Consideration of a multidisciplinary approach is critical in patients with concomitant vaginal prolapse. Surgeons must weigh their familiarity with each approach and should have in their armamentarium both perineal and abdominal approaches. Previous barriers to abdominal procedures, such as age and comorbidities, are waning as minimally invasive approaches have gained acceptance. Laparoscopic ventral rectopexy is one such approach offering relatively low morbidity, low recurrence rates, and good functional improvement. However, proficiency with this procedure may require advanced training. Robotic rectopexy is another burgeoning approach which facilitates suturing in the pelvis. Successful rectal prolapse surgeries improve function and have low recurrence rates, though it is important to note that correcting the prolapse does not assure functional improvement.

Effect of BMI on outcomes in proctectomy.

BACKGROUND: The unique surgical challenges of proctectomy may be amplified in obese patients. We examined surgical outcomes of a large, diverse sample of obese patients undergoing proctectomy. OBJECTIVE: The purpose of this work was to determine whether increased BMI is associated with increased complications in proctectomy. DESIGN: This was a retrospective review. SETTINGS: The study uses the American College of Surgeons National Surgical Quality Improvement Program database (2010 and 2011). PATIENTS: Patients included were those undergoing nonemergent proctectomy, excluding rectal prolapse cases. Patients were grouped by BMI using the World Health Organization classifications of underweight (BMI <18.5); normal (18.5-24.9); overweight (25.0-29.9); and class I (30.0-34.9), class II (35.0-39.9), and class III (≥40.0) obesity. MAIN OUTCOME MEASURES: We analyzed the effect of preoperative and intraoperative factors on 30-day outcomes. Continuous variables were compared with Wilcoxon rank-sum tests and proportions with the Fisher exact or χ tests. Logistic regression controlled for the effects of multiple risk factors. RESULTS: Among 5570 patients, class I, II, and III obesity were significantly associated with higher rates of overall complications (44.0%, 50.8%, and 46.6% vs 38.1% for normal-weight patients; p < 0.05). Superficial wound infection was significantly higher in classes I, II, and III (11.6%, 17.8%, and 13.0% vs 8.0% for normal-weight patients; p < 0.05). Operative times for patients in all obesity classes were significantly longer than for normal-weight patients. On multivariate analysis, an obese BMI independently predicted complications; ORs (95% CIs) were 1.36 (1.14-1.62) for class I obesity, 1.99 (1.54-2.54) for class II, and 1.42 (1.02-1.96) for class III. LIMITATIONS: This study was a retrospective design with limited follow-up. CONCLUSIONS: Class I, II, and III obese patients were at significantly increased risk for morbidity compared with normal BMI patients. Class II obese patients had the highest rate of complications, a finding that deserves further investigation.

A matched case-control study of IBD-associated colorectal cancer: IBD portends worse outcome.

BACKGROUND AND OBJECTIVES: The effect of inflammatory bowel disease (IBD) on outcome in patients with colorectal cancer (CRC) remains unclear. Our objective is to evaluate oncologic outcomes of patients with IBD-associated CRC. METHODS: We retrospectively reviewed a prospectively maintained database to identify patients with IBD-associated CRC. Clinicopathologic variables and overall survival were compared to patients with sporadic CRC using a 2:1 matched-controlled analysis. RESULTS: Fifty-five patients with IBD and CRC were identified. On univariate analysis, CRC patients with IBD had a significantly shorter median overall survival (68.2 months vs. 204.3 months, P = 0.01) compared to patients with sporadic CRC. On multivariate analysis, after adjusting for N and M stage, IBD was associated with an increased risk of death compared to sporadic CRC (HR = 2.011, 95% CI 1.24-3.23, P = 0.004). Stage 3 CRC patients with IBD in particular showed significantly decreased survival (23.0 vs. 133.9 months, P = 0.008). CONCLUSIONS: In this study, patients with node-positive IBD-associated CRC had a significant increased risk of death and a shorter overall survival than those with sporadic disease and may require tailored adjuvant therapy and surveillance protocols. Continued investigation to elucidate the mechanisms that contribute to these observations is justified.

An initial experience with 85 consecutive robotic-assisted rectal dissections: improved operating times and lower costs with experience.

BACKGROUND: Data are limited about the robotic platform in rectal dissections, and its use may be perceived as prohibitively expensive or difficult to learn. We report our experience with the initial robotic-assisted rectal dissections performed by a single surgeon, assessing learning curve and cost. METHODS: Following IRB approval, a retrospective chart review was conducted of the first 85 robotic-assisted rectal dissections performed by a single surgeon between 9/1/2010 and 12/31/2012. Patient demographic, clinicopathologic, procedure, and outcome data were gathered. Cost data were obtained from the University HealthSystem Consortium (UHC) database. The first 43 cases (Time 1) were compared to the next 42 cases (Time 2) using multivariate linear and logistic regression models. RESULTS: Indications for surgery were cancer for 51 patients (60 %), inflammatory bowel disease for 18 (21 %), and rectal prolapse for 16 (19 %). The most common procedures were low anterior resection (n = 25, 29 %) and abdominoperineal resection (n = 21, 25 %). The patient body mass index (BMI) was statistically different between the two patient groups (Time 1, 26.1 kg/m(2) vs. Time 2, 29.4 kg/m(2), p = 0.02). Complication and conversion rates did not differ between the groups. Mean operating time was significantly shorter for Time 2 (267 min vs. 224 min, p = 0.049) and remained significant in multivariate analysis. Though not reaching statistical significance, the mean observed direct hospital cost decreased ($17,349 for Time 1 vs. $13,680 for Time 2, p = 0.2). The observed/expected cost ratio significantly decreased (1.47 for Time 1 vs. 1.05 for Time 2, p = 0.007) but did not remain statistically significant in multivariate analyses. CONCLUSIONS: Over the series, we demonstrated a significant improvement in operating times. Though not statistically significant, direct hospital costs trended down over time. Studies of larger patient groups are needed to confirm these findings and to correlate them with procedure volume to better define the learning curve process.

Characteristics and symptomatology of colorectal cancer in the young.

BACKGROUND: The incidence of colorectal cancer in patients <50 years has rapidly risen recently. Understanding the presenting symptoms may facilitate earlier diagnosis. We aimed to delineate patient characteristics, symptomatology, and tumor characteristics of colorectal cancer in a young population. METHODS: A retrospective cohort study was conducted evaluating patients <50 years diagnosed between 2005 and 2019 with primary colorectal cancer at a university teaching hospital. The number and character of colorectal cancer-related symptoms at presentation was the primary outcome measured. Patient and tumor characteristics were also collected. RESULTS: Included were 286 patients with a median age of 44 years, with 56% <45 years. Nearly all patients (95%) were symptomatic at presentation, with 85% having 2 or more symptoms. The most common symptoms were pain (63%), followed by change in stool habits (54%), rectal bleeding (53%), and weight loss (32%). Diarrhea was more common than constipation. More than 50% had symptoms for at least 3 months before diagnosis. The number and duration of symptoms were similar in patients older than 45 compared to those younger. Most cancers were left-sided (77%) and advanced stage at presentation (36% stage III, 39% stage IV). CONCLUSION: In this cohort of young patients with colorectal cancer, the majority presented with multiple symptoms having a median duration of 3 months. It is essential that providers be mindful of the ever-increasing incidence of colorectal malignancy in young patients, and that those with multiple, durable symptoms should be offered screening for colorectal neoplasms based on symptoms alone.

Surgical management of large, connected perineal and pelvic epidermal inclusion cysts mimicking a dumbbell-shaped lesion in an adult male.

INTRODUCTION AND IMPORTANCE: Epidermal inclusion cysts are a common benign finding, and they are predominantly asymptomatic. They can rarely form in the pelvis or abdomen, however, and may cause symptoms secondary to mass effect. This case highlights management of an anterectal epidermal inclusion cyst connected to the perineal cyst, mimicking a dumbbell-shaped lesion, found in a male. CASE PRESENTATION: This is a unique case of a 21-year-old Caucasian male with a palpable perineal mass, lower extremity hypoesthesia, and constipation who was found to have a complex-shaped cyst on computed tomography and magnetic resonance imaging. This was ultimately managed with a two-stage perineal and transabdominal resection. CLINICAL DISCUSSION: This case highlights that perineal epidermal inclusion cysts may have pelvic extension, especially in patients with additional new-onset neurologic, gastrointestinal, or urologic symptoms. These symptoms should completely resolve after resection. Additionally, resection is recommended to prevent complications including malignant degeneration and fistulization. CONCLUSION: This is the first reported case of an anterectal, epidermal inclusion cyst connected to a perineal cyst found in a male. Perineal and pelvic cysts may be synchronous and may be connected through the pudendal canal. These masses can be safely removed via a combined perineal and transabdominal resection. The connecting portion of lesions that have both pelvic and perineal components should be meticulously identified and dissected because even a thin, patent segment - if left unresected - may result in lesion recurrence.

Robotic surgery training during general surgery residency: a survey comparing attitudes towards a robotic training curriculum within general surgery, urology, and OBGYN residents and attendings.

General surgery residents are increasingly exposed to robotic surgery during their training. However, there is no standardized robotic educational curriculum across United States residency programs. Prior to implementing a robotic surgery curriculum, we surveyed our residents and attendings to ascertain their attitude towards robotic surgery training in residency. An anonymous survey was distributed to all general surgery, obstetrics and gynecology (OBGYN), and urology residents, and their respective attending staff at our institution. Responses were compared between residents, attendings, and specialty. Twenty-six (72% response rate) general surgery residents and 18 (47%) subspecialty residents (OBGYN and urology) responded to the survey. Among attendings, 21 general surgery (32%) and 18 subspecialty staff (27%) responded. The majority of general surgery residents and attendings agreed that a robotic surgery curriculum should be implemented in the general surgery residency program (100 vs 86%, p = 0.04). Subspecialty residents also believed a formal curriculum should be implemented within their respective programs (100%). There was no statistically significant difference between general surgery and subspecialty resident responses. The majority of general surgery and subspecialty attendings responded that they would want a robotic surgery curriculum if they were currently residents (76 vs 94%, p = 0.12). The majority of general surgery residents and attendings at our institution believe a robotic surgery curriculum should be offered during residency. This attitude is similar to those of the subspecialty residents and attendings. A surgical education initiative should be developed to create a standardized training program to assure teaching of basic technical skills in robotic surgery before trainees enter clinical practice.

Intra-abdominal and Anorectal Abscesses.

Intra-abdominal and anorectal abscesses are common pathologies seen in both inpatient and outpatient settings. To decrease morbidity and mortality, early diagnosis and treatment are essential. After adequate drainage via a percutaneous or incisional approach, patients need to be monitored for worsening symptoms or recurrence and evaluated for the underlying condition that may have contributed to abscess formation.

Staged Approaches to Restorative Proctocolectomy with Ileoanal Pouch-When and Why?

Restorative proctocolectomy (RPC) with ileal pouch anal-anastomosis (IPAA) is commonly performed for patients with ulcerative colitis, familial adenomatous polyposis, and selected phenotypes of Crohn's disease (CD). Due to concerns about the effects of surgical complications on pouch functional outcomes, debate remains surrounding when and whether RPC with IPAA should be performed in a staged manner. Particularly debated are the timings of the IPAA, whether it is constructed at time of the proctocolectomy and whether to utilize temporary fecal diversion with a loop ileostomy. RPC with IPAA can be performed in one, two, or three stages, with each stage typically separated by 3-6 months. Proponents of a staged approach argue that poor pouch function, which is often a result of IPAA complications, including leak and infection, can be difficult to overcome and mandate additional, major surgeries, and that staging pouch creation and pairing with a protective ileostomy reduce those complications. However, subjecting patients to multiple surgeries and prolonging their time with an ileostomy present unique risks as well. Surgeons' experience and preference and patient characteristics need to be considered when determining operative planning. Highly selected patients with CD can be considered for RPC with IPAA, although with an acknowledgment of inherently higher pouch failure rates. Understanding the short- and long-term consequences of RPC with IPAA construction can help surgeons determine the appropriate approach.
