CONTEXT: Diagnosis and treatment of cystic neoplasms of the pancreas increased significantly in the last decades. There are only a few Brazilian publications on these tumors. The majority of them are limited to reports of one or few cases. OBJECTIVE: To present our experience with 27 patients with cystic neoplasms of the pancreas. METHODS: Demographic data, clinical manifestations, diagnostic exams, surgical procedures, postoperative complications, and follow-up data of 27 patients with cystic neoplasms of the pancreas were analyzed, according to the histological type of the tumor. RESULTS: There were 10 (37%) serous cystic tumors, 10 (37%) mucinous cystic tumors, 4 (15%) intraductal papillary mucinous tumors, and 3 (11%) solid pseudopapillary tumors or Frantz tumor. All serous cystic tumors, 6 (60%) mucinous tumors, 2 (50%) intraductal papillary mucinous tumors, and 2 (67%) solid pseudopapillary tumors were benign. The age of the patients varied from 31 to 82 years and all tumors were more common in female. Two patients had been treated previously as a pseudocyst. Surgical procedures depended on the location and extension of the tumor. Two patients underwent only laparotomy with tumor biopsy, one cholecystectomy with Roux-en-Y hepaticojejunostomy for jaundice treatment, 6 pancreatoduodenectomy, and 18 partial pancreatectomy. The most common postoperative complication was pancreatic fistula (n = 5; 19%). One patient died of necrotic pancreatitis. Of the 10 patients with serous cystic tumor, only 1 had tumor recurrence at the section border. The three patients with mucinous cystoadenocarcinoma in which was not possible to resect the tumor, died 6 to 24 months after laparotomy. The six patients with benign mucinous tumors did not have tumor recurrence. CONCLUSIONS: The most common cystic neoplasms of the pancreas are serous and mucinous cysts. These tumors are more frequent in female. Although almost all serous cysts are benign, 40% of mucinous cysts are malign. Misdiagnosis may delay appropriate treatment and increase mortality. RACIONAL: O diagnóstico e tratamento das neoplasias císticas do pâncreas aumentaram significativamente nas últimas décadas. Existem poucas publicações brasileiras sobre estes tumores, sendo que a maioria é limitada à descrição de um ou poucos casos. OBJETIVO: Apresentar a experiência com 27 pacientes com neoplasia cística do pâncreas. MÉTODOS: Os dados demográficos, quadro clínico, exames complementares, procedimento cirúrgico com as suas complicações e a evolução pós-operatória de 27 pacientes com neoplasia cística do pâncreas foram analisados, conforme o tipo histológico do tumor. RESULTADOS: O exame anatomopatológico evidenciou 10 (37%) casos de tumor seroso, 10 (37%) de tumor mucinoso, 4 (15%) de neoplasia intraductal papilar mucinosa e 3 (11%) de neoplasia sólida pseudopapilar ou tumor de Frantz. Todos os tumores serosos, seis (60%) mucinosos, dois (50%) tumores intraductais papilares mucinosos e dois (67%) tumores sólidos pseudopapilares eram benignos. A idade dos pacientes variou amplamente de 31 a 82 anos e o sexo feminino predominou em todos os tipos de tumores. Dois pacientes tinham sido tratados previamente como pseudocisto de pâncreas. As operações realizadas dependiam da localização e extensão do tumor. Dois pacientes foram submetidos somente a laparotomia com biopsia do tumor, 1 a colecistectomia e hepaticojejunostomia em Y-de-Roux para aliviar a icterícia, sem ressecção da neoplasia, 6 a pancreatoduodenectomia e 18 a pancreatectomia parcial. A complicação pós-operatória mais comum foi fístula pancreática (n = 5; 19%). Um paciente morreu no pós-operatório imediato por pancreatite necrótica. Dos 10 pacientes com cistoadenoma seroso, apenas 1 apresentou recidiva próxima à borda de secção do tumor. Os três pacientes com cistoadenocarcinomas mucinosos em que não foi realizada a ressecção do tumor foram a óbito de 6 a 24 meses após a operação. Os seis pacientes com tumores mucinosos benignos não apresentaram recidiva. CONCLUSÕES: As neoplasias císticas pancreáticas mais comuns são os cistos serosos e os mucinosos. Estes tumores ocorrem predominantemente no sexo feminino. Apesar de quase todos os tumores serosos serem benignos, uma percentagem elevada (40%) de tumores mucinosos é maligna. O não reconhecimento desses tumores pode retardar o tratamento adequado e ser associado à elevada mortalidade.

Although laparoscopic inguinal herniorrhaphy is considered safe, several complications may occur. This study aimed to evaluate the complications observed in 780 laparoscopic inguinal herniorrhaphies at the authors’ hospital. All the patients who underwent laparoscopic inguinal herniorrhaphy at the authors’ hospital during a period of 11 years were enrolled retrospectively in this study. Patient demographics, operative data, and intra- and postoperative complications were evaluated. A total of 569 patients underwent 780 laparoscopic inguinal herniorrhaphies. The male-to-female ratio was 8.8 to 1, and the mean age was 54.8 ± 15.7 years. Hernia recurrence was recognized in 14 patients (2.5%). Intra- and postoperative complications were diagnosed in 28 (4.9%) and 35 (6.2%) patients respectively. There was no mortality. The most common intraoperative complication was extensive subcutaneous emphysema. Two patients with extensive subcutaneous emphysema had cardiac arrhythmia. Small bowel perforation and bladder perforation occurred in one patient each. One patient had extensive preperitoneal infection caused by Mycobacterium massiliense, which required mesh removal, tissue debridement, and prolonged antibiotic therapy. Although the mortality rate is low, potentially life-threatening complications such as small bowel and bladder perforation may be experienced by patients subjected to laparoscopic herniorrhaphy.
