Sobrevida após exenteração pélvica em câncer de colo de útero recidivado: uma série de cinco casos / Survival after pelvic exenteration in recurrent cervical cancer: a series of five cases

A exenteração pélvica pode curar pacientes com câncer de colo do útero com recorrência central após radioterapia e quimioterapia. A avaliação pré-operatória é essencial para excluir doença metastática e evitar cirurgias desnecessárias nesse cenário. O objetivo do presente estudo é avaliar a sobrevida de uma série de casos de pacientes submetidas à exenteração pélvica em clínica privada de Teresina. Este é o resultado parcial de um estudo observacional, retrospectivo, transversal e descritivo, realizado em uma clínica privada especializada no tratamento do câncer em Teresina, PI, Brasil, de junho de 2002 a fevereiro de 2020. Cinco pacientes foram incluídas no estudo, com idades entre 29 e 62 anos. No presente estudo, a sobrevida mediana foi de 44,8 meses. Duas pacientes estão vivas e sem doença com seguimento de 201 e 5 meses, respectivamente.(AU)

Pelvic exenteration can heal patients with cervical cancer with central recurrence after radiotherapy and / or chemotherapy.

The objective of the present study is to evaluate the survival of a series of cases of patients submitted to pelvic exenteration in a private clinic in Teresina. This is the partial result of an observational, retrospective, cross-sectional and descriptive study, conducted at a private clinic specialized in cancer treatment in Teresina, Brazil, from June 2002 to February 2020.

Double barreled wet colostomy. Case report and description of the surgical technique / Colostomia úmida em dupla-boca. Relato de caso e descrição da técnicacirúrgica

ABSTRACT Pelvic exenteration has showed to be beneficial therapeutically and palliatively in locally advanced colorectal cancer. Reconstruction of urinary transit posterior to a cystectomy has always been challenging with many associated complications. We present a 58-year-old male with locally advanced rectal cancer in which a pelvic exenteration and a double-barreled wet colostomy (DBWC) was created for urinary reconstitution. We present the surgical technique of DBWC. DBWC is a good alternative to other urinary reconstructions because fecal and urinary derivation occurs in only one stoma, the stoma output is easier to manage, and fewer complications are seen compared to other urinary reconstructions. Long-term surveillance is mandatory in patients with a DBWC because there is an increased risk of neoplasm in the reservoir.

RESUMO A exenteração pélvica mostrou-se benéfica, tanto terapêutica quanto paliativamente, em casos de câncer colorretal localmente avançado. A reconstrução do trânsito urinário após uma cistectomia sempre foi desafiadora, com muitas complicações associadas. Os autores apresentam o caso de um homem de 58 anos de idade com câncer retal localmente avançado, submetido a uma exenteração pélvica e uma colostomia úmida em dupla-boca (CUDB) para reconstituição urinária. Os autores apresentam a técnica cirúrgica da CUDB, uma boa alternativa para outras reconstruções urinárias, já que a derivação fecal e urinária ocorre em apenas um estoma, a saída do estoma é mais fácil de gerenciar e o método apresenta menos complicações em comparação com outras reconstruções urinárias. A vigilância a longo prazo é obrigatória em pacientes com CUDB, pois há um risco aumentado de neoplasia no reservatório.

Pelvic exenteration and sphincter preservation: an analysis of 96 cases.

BACKGROUND: Pelvic exenteration (PE) is characterized by its technical complexity and morbidity rate. Appropriate patient selection prior to the operation allows for more conservative surgeries, preserving sphincters, and continent reconstruction of the intestinal and urinary tract, contributing to better results. METHODS: Between 1980 and 2000, 96 PE were performed. Factors related to sphincter preservation as well as factors associated to prognosis were respectively analyzed. RESULTS: Of the 96 PE, at least one sphincter in 36 patients was preserved (37.5%). In the 1990s, the sphincter preservation rate was significantly higher than in the 1980s (47.6 vs. 18.2%) (P = 0.005). More serious complications happened in 19.8% of the patients and the post-operative mortality rate was 15.6%. The post-operative complication rate was not influenced by sphincter preservation (P = 0.276). In nine patients, the resection margins were compromised microscopically (R1) and in five patients, there were macroscopically compromised (R2). The resection margins were not influenced by the type of surgery (P = 0.104), nor by the preservation of sphincters (P = 0.881). Twenty-three patients experienced relapses, 13 being local, eight distant, and two local and distant. Disease free survival at 5 years was 40.5%, and the primary site of the tumor was a factor associated to differences in disease free survival (P = 0.027). Overall 5-year survival was 41.9% and was significantly associated to the number of organs compromised (P = 0.040) and sphincter preservation (P = 0.026). Patients who were submitted to R0 type resection had a median survival of 40.9 months, while R1 and R2 type resections had a median 21.2 month survival. CONCLUSIONS: The appropriate pre-operative selection of the patient and rigorous oncological criteria permit PE to be performed while preserving the sphincters in selected cases, without harming survival rates.
