Diverticulitis with abscess formation: Outcomes of non-operative management and nomogram for predicting emergency surgery: The Diplicab Study Collaborative Group.

BACKGROUND: To assess short- and long-term outcomes from non-surgical management of diverticulitis with abscess formation and to develop a nomogram to predict emergency surgery. METHODS: This nationwide retrospective cohort study was performed in 29 Spanish referral centers, including patients with a first episode of a diverticular abscess (modified Hinchey Ib-II) from 2015 to 2019. Emergency surgery, complications, and recurrent episodes were analyzed. Regression analysis was used to assess risk factors, and a nomogram for emergency surgery was designed. RESULTS: Overall, 1,395 patients were included (1,078 Hinchey Ib and 317 Hinchey II). Most (1,184, 84.9%) patients were treated with antibiotics without percutaneous drainage, and 194 (13.90%) patients required emergency surgery during admission. Percutaneous drainage (208 patients) was associated with a lower risk of emergency surgery in patients with abscesses of ≥5 cm (19.9% vs 29.3%, P = .035; odds ratio 0.59 [0.37-0.96]). The multivariate analysis showed that immunosuppression treatment, C-reactive protein (odds ratio: 1.003; 1.001-1.005), free pneumoperitoneum (odds ratio: 3.01; 2.04-4.44), Hinchey II (odds ratio: 2.15; 1.42-3.26), abscess size 3 to 4.9 cm (odds ratio: 1.87; 1.06-3.29), abscess size ≥5 cm (odds ratio: 3.62; 2.08-6.32), and use of morphine (odds ratio: 3.68; 2.29-5.92) were associated with emergency surgery. A nomogram was developed with an area under the receiver operating characteristic curve of 0.81 (95% confidence interval: 0.77-0.85). CONCLUSION: Percutaneous drainage must be considered in abscesses ≥5 cm to reduce emergency surgery rates; however, there are insufficient data to recommend it in smaller abscesses. The use of the nomogram could help the surgeon develop a targeted approach.

Rabdomiosarcoma botrioides congénito de vulva / Congenital botryoid rhabdomyosarcoma of the vulva

El rabdomiosarcoma es el tumor maligno de partes blandas más frecuente en la edad pediátrica; sin embargo, la localización vulvar y la aparición congénita son excepcionales. Presentamos el caso de una niña recién nacida con un rabdomiosarcoma botrioides de vulva tratada con quimioterapia, cirugía conservadora y trasplante autólogo. El rabdomiosarcoma botrioides es una variante del tipo embrionario que crece típicamente en órganos huecos con revestimiento mucoso desde donde puede extenderse hacia la superficie corporal. El tratamiento del rabdomiosarcoma botriodes del área genitourinaria se basa en la poliquimioterapia y, si es necesario, se puede complementar con radioterapia y cirugía conservadora, consiguiéndose de este modo un pronóstico excelente y escasas secuelas funcionales a largo plaz

Rhabdomyosarcoma is the most frequent malignant soft tissue tumor in pediatric patients; however, the vulvar location and congenital appearance are exceptional. We present the case of a newborn girl with botryoid rhabdomyosarcoma of the vulva, treated with chemotherapy, conservative surgery and autologous transplant. Botryoid rhabdomyosarcoma is a variation of embryonal rhabdomyosarcoma that typically grows in mucosa-lined hollow organs, from where it can spread to the body surface. The treatment of botryoid rhabdomyosarcoma in the genito-urinary area is based on polychemotherapy, and it can be complemented with radiotherapy and conservative surgery if necessary, thus resulting in an excellent prognosis and few long-term functional sequelae
