Anaphylactic Shock to Intravenous Indocyanine Green During a Robotic Right Colectomy.

Intravenous indocyanine green (IV ICG) is regarded as a safe immunofluorescence agent used to assess bowel perfusion prior to creating bowel anastomoses and aids in ureter identification during intra-abdominal surgery. We report the first instance of anaphylactic shock to IV ICG after prior toleration of ICG via an intra-ureteral route. Shortly after administering IV ICG, our patient became hypotensive and hypoxic requiring chest compressions, vasoactive medications, and thoracostomy tubes prior to identifying the symptoms as an allergic reaction. Anaphylaxis is not a recognized side effect of ICG and was not immediately considered. As ICG becomes increasingly utilized as an immunofluorescence agent among surgical specialties, increased awareness and recognition of anaphylactic shock as a potential side effect of ICG may lead to expedited diagnoses, treatment, and more critical evaluation of indications for future use. Additionally, our patient first tolerated intra-ureteral administration without a systemic reaction, suggesting a possible sensitization mechanism.

Early Urinary Catheter Removal After Colectomy for Colovesical Fistula is Not Associated With Increased Postoperative Complications.

BACKGROUND: Management of the bladder defect during colectomy for colovesical fistula (CVF) and recommendations for duration of urinary catheter drainage are inconsistent. This study aimed to determine if urinary catheter drainage duration was associated with postoperative complications. METHODS: Retrospective single institution cohort study of patients undergoing resection for diverticular CVF from 2015 through 2021. Urinary catheter drainage was defined as Early (≤7 days postoperative and then subdivided into 1-2 days, 3-5 days, 6-7 days), and Late (>7 days postoperative). Primary outcome was a composite measure of postoperative bladder leak, surgical site infection-III, sepsis, reoperation, and postoperative length-of-stay ≥7 days. RESULTS: There were 73 patients-64 Early group and 9 Late group. Composite measure between groups (Early 25% vs Late 33.33%, P = .688) was not significantly different. The Late group had more patients with large bladder defects (33.3% vs 7.8%, P = .054), significantly more patients who underwent suture repair (55.6% vs 14.1%, P = .01), and significantly more patients that had an intraoperative pelvic drain (66.7% vs 15.6%, P = .003). After propensity score inverse weighting, the Late group had significantly more cystogram-detected postoperative bladder leaks (P = .002) and ileus (P = .042) than the Early group. There were no bladder leaks or ileus in those who had urinary catheter removal on postoperative days 1-2. CONCLUSIONS: Early urinary catheter removal was associated with no increase in bladder leaks and fewer postoperative complications after definitive management of CVF. Further investigation is required to determine if intraoperative bladder leak testing and postoperative cystograms are useful adjuncts in decision making.

A Single-Institution Analysis of Targeted Colorectal Surgery Enhanced Recovery Pathway Strategies That Decrease Readmissions.

BACKGROUND: Decreasing readmissions is an important quality improvement strategy. Targeted interventions that effectively decrease readmissions have not been fully investigated and standardized. OBJECTIVE: The purpose of this study was to assess the effectiveness of interventions designed to decrease readmissions after colorectal surgery. DESIGN: This was a retrospective comparison of patients before and after the implementation of interventions. SETTING: This study was conducted at a single institution dedicated enhanced recovery pathway colorectal surgery service. PATIENTS: The study group received quality review interventions that were designed to decrease readmissions: preadmission class upgrades, a mobile phone app, a pharmacist-led pain management strategy, and an early postdischarge clinic. The control group was composed of enhanced recovery patients before the interventions. Propensity score weighting was used to adjust patient characteristics and predictors for imbalances. MAIN OUTCOME MEASURE: The primary outcome was 30-day readmissions. Secondary outcomes included emergency department visits. RESULTS: There were 1052 patients in the preintervention group and 668 patients in the postintervention group. After propensity score weighting, the postintervention cohort had a significantly lower readmission rate (9.98% vs 17.82%, p < 0.001) and emergency department visit rate (14.58% vs 23.15%, p < 0.001) than the preintervention group, and surgical site infection type I/II was significantly decreased as a readmission diagnosis (9.46% vs 2.43%, p = 0.043). Median time to readmission was 6 (interquartile 3-11) days in the preintervention group and 8 (3-17) days in the postintervention group (p = 0.21). Ileus, acute kidney injury, and surgical site infection type III were common reasons for readmissions and emergency department visits. LIMITATIONS: A single-institution study may not be generalizable. CONCLUSION: Readmission bundles composed of targeted interventions are associated with a decrease in readmissions and emergency department visits after enhanced recovery colorectal surgery. Bundle composition may be institution dependent. Further study and refinement of bundle components are required as next-step quality metric improvements.

ANLISIS EN UNA SOLA INSTITUCIN DE LAS CIRUGAS COLORECTALES CON VAS DE RECUPERACIN DIRIGIDA AUMENTADA QUE REDUCEN LOS REINGRESOS: ANTECEDENTES:La reducción de los reingresos es una importante estrategia de mejora de la calidad. Las intervenciones dirigidas que reducen eficazmente los reingresos no se han investigado ni estandarizado por completo.OBJETIVO:El propósito de este estudio fue evaluar la efectividad de las intervenciones diseñadas para disminuir los reingresos después de la cirugía colorrectal.DISEÑO:Comparación retrospectiva de pacientes antes y después de la implementación de las intervenciones.ESCENARIO:Una sola institución dedicada al Servicio de cirugía colorrectal con vías de recuperación dirigida aumentadaPACIENTES:El grupo de estudio recibió intervenciones de revisión de calidad que fueron diseñadas para disminuir los reingresos: actualizaciones de clases previas a la admisión, una aplicación para teléfono móvil, una estrategia de manejo del dolor dirigida por farmacéuticos y alta temprana de la clínica. El grupo de control estaba compuesto por pacientes con recuperación mejorada antes de las intervenciones. Se utilizó la ponderación del puntaje de propensión para ajustar las características del paciente y los predictores de los desequilibrios.PARÁMETRO DE RESULTADO PRINCIPAL:El resultado primario fueron los reingresos a los 30 días. Los resultados secundarios incluyeron visitas al servicio de urgencias.RESULTADOS:Hubo 1052 pacientes en el grupo de preintervención y 668 pacientes en el grupo de posintervención. Después de la ponderación del puntaje de propensión, la cohorte posterior a la intervención tuvo una tasa de reingreso significativamente menor (9,98% frente a 17,82%, p <0,001) y una tasa de visitas al servicio de urgencias (14,58% frente a 23,15%, p <0,001) que el grupo de preintervención y la infección del sitio quirúrgico tipo I / II se redujo significativamente como diagnóstico de reingreso (9,46% frente a 2,43%, p = 0,043). La mediana de tiempo hasta la readmisión fue de 6 [IQR 3, 11] días en el grupo de preintervención y de 8 [3, 17] días en el grupo de posintervención (p = 0,21). El íleo, la lesión renal aguda y la infección del sitio quirúrgico tipo III fueron motivos frecuentes de reingresos y visitas al servicio de urgencias.LIMITACIONES:El estudio de una sola institución puede no ser generalizable.CONCLUSIÓNES:Los paquetes de readmisión compuestos por intervenciones dirigidas se asocian con una disminución en las readmisiones y las visitas al departamento de emergencias después de una cirugía colorrectal con vías de recuperación dirigida aumentada. La composición del paquete puede depender de la institución. Se requieren más estudios y refinamientos de los componentes del paquete como siguiente paso de mejora de la métrica de calidad.

A pilot study of venous duplex ultrasound parameters in healthy children.

OBJECTIVE: The spectrum of chronic venous disease (CVD) in adults is well documented, whereas there is a paucity of data published commenting on pediatric CVD. We previously identified that there is often venous reflux present in cases of pediatric lower extremity edema despite an alternative confirmed diagnosis. To further assess the clinical significance of this venous reflux, this study aimed to elicit venous parameters in healthy pediatric controls. METHODS: Healthy pediatric volunteers aged 5 to 17 years were recruited for venous reflux study. A comprehensive venous reflux study was performed with the patient standing. Vein diameter, patterns of valvular reflux, and accessory venous anatomy were examined in the deep and superficial venous systems. RESULTS: Eighteen children including 10 boys and 8 girls were studied. Five volunteers were aged 5 to 8 years, six volunteers were aged 9 to 12 years, and seven volunteers were aged 13 to 17 years. Great saphenous vein (GSV) diameter at the saphenofemoral junction significantly increased with age. Deep vein valve closure time (VCT) did not differ significantly between groups, whereas GSV VCT was significantly higher in the 9- to 12-year age group. Incidental venous insufficiency was identified in 60% of children aged 5 to 8 years (n = 3), 50% of children aged 9 to 12 years (n = 3), and 57% of children aged 13 to 17 years (n = 4). All superficial venous reflux was confined to the GSV; there were no cases of isolated deep venous reflux. Reflux was identified at multiple GSV stations in 60% of children. There was no significant difference in incompetent GSV VCT in comparing children with and without deep venous reflux. Accessory superficial veins were identified in 20% of children aged 5 to 8 years (n = 1), 50% of children aged 9 to 12 years (n = 3), and 43% of children aged 13 to 17 years (n = 3). The presence of an accessory saphenous vein was not associated with deep venous reflux in any patient, and only 29% of those with accessory saphenous venous anatomy had evidence of superficial venous (GSV) reflux. CONCLUSIONS: The GSV continues to grow in diameter through the teenage years. Incidental valvular incompetence and GSV reflux are common. The presence of accessory saphenous veins is similarly common and not associated with venous reflux. The clinical significance and natural history of this incidental venous reflux remain unclear. Future research should determine whether these changes seen in the pediatric age group lead to CVD during later years of life.
