Predictive Value of C-Reactive Protein for Infectious Complications After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: A Single-Center Prospective Study.

BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) can be associated with significant morbidity and prolonged hospital stay. Postoperative infections account for a high burden of these complications. This study aimed to assess the predictive value of postoperative C-reactive protein (CRP) levels for overall infectious complications and anastomotic leaks. METHODS: This was a single-center prospective study of patients undergoing CRS and HIPEC for peritoneal metastases between 2018 and 2020 at Maisonneuve-Rosemont Hospital in Montreal, QC, Canada. CRP levels were measured daily for 10 days following surgery. A comparison was made between patients with infectious complications and those without. RESULTS: Ninety-nine patients were included. Thirty patients had infectious complications (30.3%) and four patients presented an anastomotic leak (4%). CRP levels were significantly higher in patients with infectious complications from postoperative days (PODs) 2-10. Daily cut-off values most accurately predicted infectious complications on day 8 (94.3 mg/L; area under the curve [AUC] 0.85, sensitivity [SE] 76.2%, specificity [SP] 94.7%, positive predictive value [PPV] 88.9%, negative predictive value [NPV] 87.8%; p < 0.0001) and day 9 (72.7 mg/L; AUC 0.89, SE 95.2%, SP 81.8%, PPV 76.9%, NPV 96.4%; p < 0.0001). Patients with infectious complications had longer operative time, higher peritoneal cancer index, and a higher number of intestinal anastomoses, while their baseline characteristics were comparable. CONCLUSION: Measurement of CRP helps predict infectious complications following CRS and HIPEC, particularly on PODs 8 and 9. Cut-off values are more accurate after the first postoperative week, especially in ruling out infectious complications.

Loop Ileostomy Closure as a 23-Hour Stay Procedure With Preoperative Efferent Limb Enteral Stimulation: A Randomized Controlled Trial.

BACKGROUND: Loop ileostomy closure is a common procedure in colorectal surgery. Often seen as a simple operation associated with a low complication rate, it still leads to lengthy hospitalizations. Reducing postoperative complications and ileus rates could lead to a shorter length of stay and even ambulatory surgery. OBJECTIVES: This study aimed to assess the safety and feasibility of ileostomy closure performed in a 23-hour hospitalization setting using a standardized enhanced recovery pathway. DESIGN: Randomized controlled trial. SETTINGS: Two high-volume colorectal surgery centers. PATIENTS: Healthy adults undergoing elective ileostomy closure from July 2019 to January 2022. INTERVENTION: All patients were enrolled in a standardized enhanced recovery pathway specific to ileostomy closure, including daily irrigation of efferent limb with a nutritional formula for 7 days before surgery. Patients were randomly allocated to either conventional hospitalization (n = 23) or a 23-hour stay (n = 24). MAIN OUTCOME MEASURES: Primary outcome was total length of stay and secondary outcomes were 30-day rates of readmission, postoperative ileus, surgical site infections, and postoperative morbidity and mortality. RESULTS: A total of 47 patients were ultimately randomly allocated. Patients in the 23-hour hospitalization arm had a shorter median length of stay (1 vs 2 days, p = 0.02) and similar rates of readmission (4% vs 13%, p = 0.35), postoperative ileus (none in both arms), surgical site infection (0% vs 4%, p = 0.49), postoperative morbidity (21% vs 22%, p = 1.00), and mortality (none in both arms). LIMITATIONS: Due to coronavirus disease 2019, access to surgical beds was greatly limited, leading to a shift toward ambulatory surgery for ileostomy closure. The study was terminated early, which affected its statistical power. CONCLUSION: Loop ileostomy closures as 23-hour stay procedures are feasible and safe. Ileus rate might be reduced by preoperative intestinal stimulation with nutritional formula through the stoma's efferent limb, although specific randomized controlled trials are needed to confirm this association.

CIERRE DE ILEOSTOMA EN ASA COMO PROCEDIMIENTO AMBULATORIO DE HORAS CON ESTMULO PREOPERATORIO ENTERAL EFERENTE ESTUDIO ALEATORIO CONTROLADO: ANTECEDENTES:El cierre de la ileostomía en asa es un procedimiento común en la cirugía colorrectal. A menudo vista como una operación simple asociada con bajas tasas de complicaciones, aún conduce a largas hospitalizaciones. La reducción de las complicaciones postoperatorias y las tasas de íleo podría conducir a una estadía hospitalaria más corta o incluso a una cirugía ambulatoria.OBJETIVOS:El presente estudio pretende evaluar la seguridad y la viabilidad del cierre de ileostomía realizadas en un entorno de hospitalización de 23 horas utilizando una vía de recuperación mejorada y estandarizada.DISEÑO:Estudio aleatorio controladoAJUSTES:Dos centros de cirugía colorrectal de gran volúmenPACIENTES:Adultos sanos sometidos a cierre electivo de ileostomía, desde Julio de 2019 hasta Enero de 2022.INTERVENCIÓN:Todos los pacientes fueron inscritos en una vía de recuperación mejorada y estandarizada específica para el cierre de la ileostomía, incluyendo la irrigación diaria de la extremidad eferente del intestino asociada a una fórmula nutricional durante 7 días previos a la cirugía. Los pacientes fueron asignados aleatoriamente en hospitalización convencional (n = 23) o a una estadía de 23 horas (n = 24).PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la duración total de la estadía hospitalaria y los resultados secundarios fueron las tasas de reingreso a los 30 días, el íleo postoperatorio, las infecciones de la herida quirúrgica, la morbilidad y mortalidad postoperatorias.RESULTADOS:Finalmente fueron randomizados un total de 47 pacientes. Aquellos que se encontraban en el grupo de hospitalización de 23 horas tuvieron una estadía media más corta (1 día versus 2 días, p = 0,02) y tasas similares de reingreso (4% vs 13%, p = 0,35), de íleo postoperatorio (ninguno en ambos brazos), de infección del sitio quirúrgico (0 vs 4%, p = 0,49), de morbilidad postoperatoria (21% vs 22%, p > 0,99) y de mortalidad (ninguna en ambos brazos).LIMITACIONES:Debido a la pandemia SARS CoV-2, el acceso a las camas quirúrgicas fue muy limitado, lo que llevó a un cambio hacia la cirugía ambulatoria para el cierre de ileostomías. El estudio finalizó anticipadamente, lo que afectó su poder estadístico.CONCLUSIÓN:Los cierres de ileostomía en asa como procedimientos de estadía de 23 horas son factibles y seguros. La tasa de íleo podría reducirse mediante la estimulación intestinal preoperatoria a través de la rama eferente del estoma asociada a fórmulas nutricionales, por lo que se necesitan estudios randomizados específicos para confirmar esta asociación.

En bloc resection of pararectal ectopic thyroid tissue: a case report.

A pararectal mass' specific diagnosis can be challenging as a broad range of both benign and malignant tumors are possible. Many of these lesions are congenital and do not require treatment, if asymptomatic. Special attention is to be paid when imaging findings are not typical. In such cases, definitive diagnostic can require surgical excision. To this day, ectopic thyroid tissue was not part of known differential diagnosis. This is the first reported case of thyroid adenoma found in the perirectal area. Ectopic thyroid gland can progress over time and include malignant transformation, although rare. It needs to be considered when managing these cases, especially in unusual locations. This case report offers a systematic approach to the atypical pararectal tumor. It shares new specific clinical experience in managing a case  of pararectal ectopic thyroid adenoma, from both a surgical and a histopathological point of view.
