Background and Objectives:Although solid pseudopapillary tumor (SPT) of the pancreas is rare, its diagnosis has increased severalfold in the past decades. We present our experience in the management of SPT, including a patient who experienced tumor rupture during laparoscopy pancreatic resection.Methods:Data on all patients with SPT who were subjected to surgical treatment were retrospectively obtained.Results:Of 20 patients evaluated, 17 (85%) were females. The mean age was 31 years. Tumor size varied from 2.7 × 1.5 to 13.5 × 10.0 cm, with a mean of 6.4 × 7.6 cm. The most common location was the tail and/or body of the pancreas (14 patients [70%]). Pancreatic tumor resection was performed in 19 patients (50%). The type of resection depended on tumor location and size: distal pancreatectomy (n = 13), pancreatoduodenectomy (n = 5), and central pancreatectomy (n = 1) Pancreatic resection was performed via laparoscopy in 7 patients who underwent distal pancreatectomy. Tumor resection was not performed in only 1 patient (5%), due to invasion of mesenteric vessels and presence of liver metastases. One patient had tumor rupture during laparoscopic resection, with no apparent macroscopic dissemination of the tumor. All 19 patients who underwent SPT resection had no tumor recurrence, including a patient with capsule invasion and another patient with tumor rupture during surgical dissection. The mean follow-up time was 38 months (range, 6–72 months).Conclusion:Complete SPT resection is possible in most patients, with a low recurrence rate. Because of its large size, laparoscopic resection of SPT's should be performed only by experienced surgeons to avoid tumor rupture.
RESUMO Objetivo: identificar fatores preditivos da síndrome da ressecção anterior do reto (SRAR) que podem contribuir para o seu diagnóstico e tratamento precoces. Métodos: estudo de coorte retrospectivo de pacientes submetidos à ressecção anterior do reto entre 2007 e 2017 no Serviço de Coloproctologia do Hospital de Clínicas da Universidade Federal do Paraná. Foram realizadas análises de curva ROC (Receiver Operating Characteristic Curve Analysis) ou COR (Característica de Operação do Receptor) para identificar os fatores preditivos da SRAR. Resultados: foram incluídos 64 pacientes com dados completos. A idade dos homens foi de 60,1±11,4 anos e 37,10% eram do sexo masculino. Vinte pacientes (32,26%) apresentaram SRAR. Os sintomas mais relatados foram evacuação incompleta (60%) e urgência (55%). Na análise univariada, a distância da anastomose à margem anal (p<0,001), terapia neoadjuvante (p=0,0014) e confecção de ileostomia no momento da ressecção (p=0,0023) foram preditivos da SRAR. Análise da curva ROC mostrou um ponto de corte de 6,5cm na distância da anastomose à margem anal como preditor da SRAR. Conclusão: distância entre anastomose e margem anal, história de terapia neoajuvante e confecção de estoma são condições que podem ajudar a predizer o desenvolvimento da SRAR. A orientação e o envolvimento na educação do paciente, bem como, o manejo precoce podem reduzir potencialmente o impacto desses sintomas na qualidade de vida dos pacientes.
