BACKGROUND: Postoperative ileus remains an issue after colorectal surgery delaying recovery and increasing the length of hospital stay and costs. OBJECTIVE: The purpose of this study was to analyze the impact of perioperative fluid management on ileus occurrence after colorectal surgery within a fully implemented enhanced recovery pathway. DESIGN: This was a retrospective cohort study of a prospectively maintained institutional database. SETTINGS: The study was conducted at a tertiary academic facility with fully implemented standardized enhanced recovery pathway over the entire study period. PATIENTS: All of the consecutive elective major colorectal resections for benign or malign indications between 2011 and 2016 were included. MAIN OUTCOME MEASURES: Postoperative ileus was defined as the need for nasogastric tube reinsertion. Perioperative fluid management and surgical outcome were compared between patients presenting with ileus and those without. Potential risk factors for ileus were identified through multinomial logistic regression. RESULTS: Postoperative ileus occurred in 377 (9%) of 4205 included patients at day 4 (interquartile range, 2–5 d). Intraoperatively, ileus patients received 3.2 ± 2.6 L of fluids, whereas the remaining patients received 2.5 ± 1.7 L (p < 0.001). Weight gain was 3.8 ± 7.1 kg in ileus patients versus 3.0 ± 6.6 kg (p = 0.272) in the remaining patients at postoperative day 1, 4.4 ± 6.5 kg versus 3.1 ± 7.0 kg (p = 0.028) at postoperative day 2, and 1.8 ± 6.0 kg versus 0.0 ± 6.0 kg at discharge (p = 0.002). The multivariable model including all significant (p < 0.05) demographic, fluid management–related, and surgical parameters retained postoperative day 0 fluids of >3 L (OR = 1.65 (95% CI, 1.13–2.41); p = 0.009), postoperative day 2 weight gain of >2.5 kg (OR = 1.49 (95% CI, 1.01–2.21); p = 0.048), and occurrence of postoperative complications (OR = 2.00 (95% CI, 1.39–2.90); p < 0.001) as independent risk factors for ileus. LIMITATIONS: This study was limited by its retrospective design. Fluid management depends on patient-, disease-, and surgery-related factors and cannot be generalized and extrapolated. CONCLUSIONS: Fluid overload and occurrence of postoperative complications were independent risk factors for postoperative ileus. This calls for action to keep perioperative fluids below suggested thresholds. See Video Abstract at http://links.lww.com/DCR/B54. ASOCIACIÓN POTENCIAL ENTRE EL MANEJO DEL LÍQUIDO PERIOPERATORIO Y EL SUCESO DE ÍLEO POSTOPERATORIO ANTECEDENTES: El íleo postoperatorio sigue siendo un problema después de una cirugía colorrectal que retrasa la recuperación y aumenta la duración de la estancia hospitalaria y los costos. OBJETIVO: Analizar el impacto del manejo del líquido perioperatorio en la incidencia de íleo después de la cirugía colorrectal dentro de una vía de recuperación mejorada totalmente implementada. DISEÑO: Estudio de cohorte retrospectivo de una base de datos institucional mantenida prospectivamente. MARCO: Centro académico terciario con una ruta de recuperación mejorada estandarizada completamente implementada durante todo el período del estudio. PACIENTES: Se incluyeron todas las resecciones colorrectales mayores electivas consecutivas para indicaciones benignas o malignas entre 2011 y 2016. MEDIDAS DE RESULTADOS PRINCIPALES: El íleo postoperatorio se definió como la necesidad de reinserción de la sonda nasogástrica. El manejo del líquido perioperatorio y el resultado quirúrgico se compararon entre los pacientes con íleo y los que no. Los posibles factores de riesgo para el íleo se identificaron mediante regresión logística multinominal. RESULTADOS: El íleo postoperatorio se ocurrió en 377 (9%) de los 4205 pacientes incluidos al cuarto día (RIC 2-5). Intraoperatoriamente, los pacientes con íleo recibieron 3.2 ± 2.6 L de líquidos, mientras que los pacientes restantes recibieron 2.5 ± 1.7 L (p < 0.001). El aumento de peso fue de 3.8 ± 7.1 kg en pacientes con íleo versus 3 ± 6.6 kg (p = 0.272) en los pacientes restantes en el día postoperatorio 1, 4.4 ± 6.5 kg vs. 3.1 ± 7 kg (p = 0.028) en el día postoperatorio 2 y 1.8 ± 6 kg versus a 0 ± 6 kg al tiempo de alta hospitalaria (p = 0.002). El modelo multivariable que incluye todos los parámetros demográficos, del manejo de líquidos y quirúrgicos significativos (p <0.05) mantuvo líquidos del día 0 después de la operación de> 3L (proporción de probabilidad 1.65, intervalo de confianza del 95% 1.13-2.41, p = 0.009), ganancia de peso de > 2.5 kg en el dia postoperatorio 2 (proporción de probabilidad 1.49, 95% intervalo de confianza 1.01-2.21, p = 0.048) y aparición de complicaciones postoperatorias (proporción de probabilidad 2, 95% intervalo de confianza 1.39-2.9, p <0.001) como factores de riesgo independientes para íleo. LIMITACIONES: Diseño retrospectivo. El manejo de líquidos depende de factores relacionados con el paciente, la enfermedad y la cirugía, y no puede generalizarse ni extrapolarse. CONCLUSIONES: La sobrecarga de líquidos y la aparición de complicaciones postoperatorias fueron factores de riesgo independientes para el íleo postoperatorio. Esto requiere medidas para mantener los líquidos perioperatorios por debajo de los umbrales sugeridos. Vea el Video del Resumen en http://links.lww.com/DCR/B54.

BACKGROUND: Controversy in performing hemorrhoidectomy and anal skin tag excision in patients with IBD stems from dated reports of nonhealing wounds resulting in proctectomy. OBJECTIVE: This study aimed to determine the safety of interventional management of hemorrhoids or anal skin tags in patients with Crohn’s disease or ulcerative colitis. DESIGN: This study is a retrospective review of patient records from 2000 to 2017. SETTING: The patient records were retrieved from a multistate health system. PATIENTS: Adult patients with IBD undergoing interventional management of hemorrhoids or skin tags were included. MAIN OUTCOME MEASURE: The primary outcome measured was the long-term requirement of proctectomy. RESULTS: Ninety-seven patients (n = 49 Crohn’s disease, 48 ulcerative colitis) underwent interventional management of hemorrhoids or anal skin tags (n =35 rubber band ligation, 27 anal skin tag excision, 21 hemorrhoidectomy, 14 excision/incision of thrombosed hemorrhoid). Thirty-day complications were observed in 5 patients (n = 4 urinary retention, 1 perianal abscess). Five patients with Crohn’s disease eventually required proctectomy at a median of 7 years after skin tag excision (range, 6 months to 10 years), but none were secondary to impaired wound healing. Two patients with ulcerative colitis who had previously undergone IPAA were subsequently diagnosed with Crohn’s disease of the pouch after skin tag excision. No other long-term complications were seen in patients with ulcerative colitis. LIMITATIONS: The study’s retrospective design does not allow identification of patients with IBD who underwent only medical management of their hemorrhoids. There is also selection bias in which patients were selected for interventional management of their disease. CONCLUSIONS: The requirement for proctectomy after hemorrhoidectomy/skin tag excision appears to be secondary to the natural disease course of perianal Crohn’s disease rather than perianal intervention. Selective hemorrhoidectomy and skin tag excision in patients with well-controlled luminal disease should be considered. See Video Abstract at http://links.lww.com/DCR/B55. HEMORROIDECTOMÍA ASOCIADA A LA EXCISIÓN DE PLICOMAS EN CASOS DE ENFERMEDAD INFLAMATORIA INTESTINAL: ¿ANUNCIO DE FATALIDAD O SIMPLEMENTE EVOLUCIÓN NATURAL DE LA ENFERMEDAD? ANTECEDENTES: Está controvertida la realización de una hemorroidectomía asociada a la excisión de plicomas ano-cutáneos en pacientes con enfermedad inflamatoria intestinal, así lo han demostrado informes detallados sobre la no cicatrisación de las heridas conllevando a una proctectomía. OBJETIVO: Determinar los margenes de seguridad en casos de tratamiento instrumental de hemorroides asociadas a la excisión de plicomas ano-cutáneos en pacientes portadores de colitis ulcerosa o enfermedad de Crohn. DISEÑO: Revisión retrospectiva de historias clinicas de pacientes entre 2000 y 2017. ENTORNO: Servicio Multiestatal de Salud. PACIENTES: Adultos con enfermedad inflamatoria intestinal sometidos a tratamiento instrumental de hemorroides asociado a la excisión de plicomas ano-cutáneos. RESULTADO PRINCIPALES: Requisitos a largo plazo para una proctectomía. RESULTADOS: Noventa y siete pacientes (49 con enfermedad de Crohn, 48 con colitis ulcerosa) se sometieron a un tratamiento instrumental de hemorroides asociada a la excisión de plicomas ano-cutáneos (35 ligadura con bandas elásticas, 27 excisión de plicomas ano-cutáneos, 21 hemorroidectomías, 14 excisiones / incisiones de hemorroides trombosadas) Se observaron complicaciones a los 30 días en cinco pacientes (4 con retención urinaria, 1 absceso perianal). Cinco pacientes con enfermedad de Crohn requirieron proctectomía en una media de 7 años después de la excisión de los plicomas ano-cutáneos (rango, 6 meses a 10 años), pero ninguno fue secundario a la mala cicatrización de la herida. Dos pacientes con colitis ulcerosa que previamente se habían sometido a una anastomosis colo-anal protegia por ilestomía fueron diagnosticados posteriormente con enfermedad de Crohn localizada en la ostomía después de la excisión de plicomas ano-cutáneos. No se observaron complicaciones a largo plazo en pacientes con colitis ulcerosa. LIMITACIONES: El diseño retrospectivo del estudio no permite la identificación de pacientes con enfermedad inflamatoria intestinal que se sometieron únicamente al tratamiento médico de las hemorroides. También existe un sesgo de selección de pacientes escogidos para tratamiento instrumental de la enfermedad hemorroidaria. CONCLUSIONES: El requisito de proctectomía después de la hemorroidectomía / excisión de plicomas anocutáneos parece ser secundario al curso de la enfermedad natural de la enfermedad de Crohn perianal en el sitio de la intervención perianal. Se debe considerar la hemorroidectomía selectiva y la excisión de plicomas ano-cutáneos solo en pacientes con enfermedad endoluminal controlada.

Abstract Background We aim to assess the impact of a multidisciplinary inflammatory bowel disease (IBD) conference on the management of patients with complex IBD. Methods Data were collected during each conference from February 2017 through October 2018 with chart review performed at 6 months to determine if conference recommendations were successfully implemented. Results Eighty-five patients were discussed. The presenting diagnosis was changed by 11.8%. Recommendations for further testing, medical therapy, and surgery were successfully implemented in 77.1%, 98.1%, and 88.4%, respectively. Conclusions This study supports the role of IBD multidisciplinary conferences in the management of patients with complex IBD.

Abstract Background The decision to either escalate medical therapy or proceed to ileocecal resection (ICR) in patients with terminal ileal Crohn disease (CD) remains largely subjective. We sought to develop a risk score for predicting ICR at 1 year from computed tomography or magnetic resonance enterography (CTE/MRE). Methods We conducted a retrospective cohort study including all consecutive adult (> 18 years) patients with imaging findings of terminal ileal CD (Montreal classification: B1, inflammatory predominant; B2, stricturing; or B3, penetrating) on CTE/MRE between January 1, 2016, and December 31, 2016. The risk for ICR at 6 months and at 1 year of CTE/MRE and risk factors associated with ICR, including demographics, CD-specific immunosuppressive therapeutics, and disease presentation at the time of imaging, were determined. Results Of 559 patients, 121 (21.6%) underwent ICR during follow-up (1.4 years [IQR 0.21–1.64 years]); the risk for ICR at 6 months and at 1 year was 18.2% (95% CI 14.7%–21.6%) and 20.5% (95% CI 16.8%–24.1%), respectively. Multivariable analysis revealed Montreal classification (B2, hazard ratio [HR] 2.73, and B3, HR 6.80, both P < 0.0001), upstream bowel dilation (HR 3.06, P < 0.0001), and younger age (19–29 years reference, 30–44 years, HR 0.83 [P = 0.40]; 45–59 years, HR 0.58 [P = 0.04], and 60+ years, HR 0.45 [P = 0.01]) to significantly increase the likelihood of ICR. A predictive nomogram for interval ICR was developed based on these significant variables. Conclusions The presence of CD strictures, penetrating complications, and upstream bowel dilation on CTE/MRE, combined with young age, significantly predict ICR. The suggested risk model may facilitate objective therapeutic decision-making.

BACKGROUND: Metabolic syndrome is associated with poorer postoperative outcomes after various abdominal operations. However, the impact of metabolic syndrome on outcomes after colorectal cancer surgery remains poorly described. OBJECTIVE: The purpose of this study was to determine the association between metabolic syndrome and short-term postoperative outcomes in patients undergoing elective colorectal cancer surgery. DESIGN: This was a retrospective cohort study. SETTINGS: This study used a national multicenter database. PATIENTS: Adult patients who underwent elective colectomy for colorectal cancer from 2010 to 2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. MAIN OUTCOME MEASURES: Thirty-day postoperative mortality and morbidity, unplanned reoperation, unplanned readmission, operative time, and length of stay were measured. RESULTS: A total of 91,566 patients were analyzed; 7603 (8.3%) had metabolic syndrome. On unadjusted analysis, metabolic syndrome was associated with an increased risk of 30-day overall morbidity, pulmonary complications, renal complications, septic complications, cardiac complications, wound complications, blood transfusion, longer length of stay, and unplanned readmissions. On multivariable analysis, metabolic syndrome remained significantly associated with renal complications (OR = 1.44 (95% CI, 1.29–1.60)), superficial surgical site infection (OR = 1.46 (95% CI, 1.32–1.60)), deep surgical site infection (OR = 1.40 (95% CI, 1.15–1.70)), wound dehiscence (OR = 1.47 (95% CI, 1.20–1.80)), and unplanned readmissions (HR = 1.24 (95% CI, 1.15–1.34)). The risks of overall morbidity, cardiac and septic complications, and prolonged length of stay for laparoscopic procedures were significantly associated with diabetes mellitus rather than metabolic syndrome as a composite entity. LIMITATIONS: This study was limited by its retrospective design and inability to analyze outcomes beyond 30 days. CONCLUSIONS: Patients with metabolic syndrome undergoing elective surgery for colorectal cancer have an increased risk of 30-day postoperative renal complications, wound complications, and unplanned hospital readmissions. A multidisciplinary approach involving lifestyle modifications and pharmacologic interventions to improve the components of metabolic syndrome should be implemented preoperatively for these patients.

BACKGROUND: Management of transsphincteric cryptoglandular fistulas remains a challenging problem and the optimal surgical approach remains elusive. Mesenchymal stem cells, increasingly being utilized for perianal Crohn’s disease, offer a novel therapy to treat cryptoglandular fistulas. OBJECTIVES: This study aimed to determine safety and feasibility of using an autologous mesenchymal stem cell-coated fistula plug in patients with transsphincteric cryptoglandular fistulas. DESIGN: This study is a phase I clinical trial. SETTING: This study was conducted at a tertiary academic medical center. PATIENTS: Adult (>18 years) male and female patients with transsphincteric cryptoglandular fistulas were selected. MAIN OUTCOMES MEASURES: The primary outcomes measured were the safety, feasibility, and efficacy of a mesenchymal stem cell-coated fistula plug in patients with transsphincteric fistulas. RESULTS: Fifteen patients (8 women, mean age 39.8 years) with a single-tract transsphincteric fistula received a mesenchymal stem cell-loaded fistula plug and were followed for 6 months. Duration of disease at the time of study enrollment was a median of 3.0 years (range, 1–13 years) with a median of 3.5 (range, 1–20) prior surgical interventions. Adverse events included 1 plug extrusion, 1 abdominal wall seroma, 3 perianal abscesses requiring drainage, and 1 patient with perianal cellulitis. There were no serious adverse events. At 6 months, 3 patients had complete clinical healing, 8 had partial healing, and 4 patients showed no clinical improvement. Radiographic improvement was seen in 11 of 15 patients. LIMITATIONS: This study was limited by the small cohort and short follow-up. CONCLUSIONS: Autologous mesenchymal stem cell-coated fistula plug treatment of transsphincteric cryptoglandular fistulas was safe and feasible and resulted in complete or partial healing in a majority of patients.

AbstractBackgroundThe present study aimed to assess the impact of perioperative fluid management on early acute kidney injury (AKI) rate and long‐term sequelae in patients undergoing elective colorectal procedures within an enhanced recovery pathway (ERP).MethodsRetrospective analysis of consecutive patients from a prospectively maintained ERP database (2011–2015) is performed. Pre‐ and postoperative creatinine levels (within 24 h) were compared according to risk (preoperative creatinine rise ×1.5), injury (×2), failure (×3), loss of kidney function and end‐stage kidney disease (RIFLE) criteria. Risk factors for early AKI were identified through logistic regression analysis, and long‐term outcome in patients with AKI was assessed.ResultsOut of 7103 patients, 4096 patients (58%) with pre‐ and postoperative creatinine levels were included. Of these, 104 patients (2.5%) presented postoperative AKI. AKI patients received higher amounts of POD 0 fluids (3.8 ± 2.4 vs. 3.2 ± 2 L, p = 0.01) and had increased postoperative weight gain at POD 2 (6 ± 4.9 vs. 3 ± 2.7 kg, p = 0.007). Independent risk factors for AKI were high ASA score (ASA ≥ 3: OR 1.7; 95% CI 1.1–2.5), prolonged operating time (>180 min: OR 1.9; 95% CI 1.3–2.9) and diabetes mellitus (OR 2.5; 95% CI 1.5–4), while minimally invasive surgery was a protective factor (OR 0.6; 95% CI 0.4–0.9). Five patients (0.1%) developed chronic kidney disease, and two of them needed dialysis after a mean follow‐up of 33.7 ± 22.4 months.ConclusionsEarly AKI was very uncommon in the present cohort of colorectal surgery patients treated within an ERP, and long‐term sequelae were exceptionally low.

AbstractAimThe present study aimed to compare functional recovery and surgical outcomes after left and right colectomies.MethodConsecutive elective left and right colon resections for benign and malignant indications, performed between 2011 and 2016 and recorded in a prospectively maintained enhanced recovery database, were analysed. Demographic and surgical items, as well as functional recovery and 30‐day complications, were compared between left‐sided and right‐sided colectomies. Multivariable analysis was performed to identify risk factors for postoperative ileus (POI).ResultsIn total, 1001 left and 1041 right colectomies were comparable regarding demographic factors; only body mass index (BMI) was higher in patients undergoing left‐sided resections (> 30 kg/m2: 33% vs 27%, P = 0.004). Malignancy (29% vs 67%, P < 0.001) and Crohn's disease (1% vs 31%, P < 0.001) were preponderant in right colectomies, whereas diverticular disease (68% vs 1%, P < 0.001) was the most common indication for left colectomy. Compliance with the enhanced recovery pathway (ERP) was comparable. While the minimally invasive approach was the preferred approach for both sides (61% vs 64%, P = 0.158), left colectomies took longer (180 ± 80 min vs 150 ± 70 min, P < 0.001), needed more perioperative fluids (3.1 ± 1.4 l vs 2.7 ± 1.5 l, P < 0.001) and resulted in greater postoperative weight gain (3.9 ± 6.5 kg vs 2.6 ± 6 kg, P = 0.025). Crohn's disease (OR = 2.64, 95% CI: 1.27–5.46) and fluid overload (OR = 2.02, 95% CI: 1.06–3.82) were independent risk factors for POI.ConclusionDespite equal ERP compliance, postoperative ileus was higher after right‐sided colectomies. This finding was associated with Crohn's disease and fluid overload.
