ABSTRACT
ABSTRACT BACKGROUND: Duodenal papilla neuroendocrine tumors (DP-NET) are rare. Surgical therapy may be recommended for their treatment. However, they have high rates of morbidity and mortality. Endoscopic papillectomy (EP) is safe and effective for complete resection of tumors at this site. OBJECTIVE: This study aimed to describe a case series of DP-NETs resected by EP and perform a literature review. METHODS: A series of patients with DP-NETs underwent EP as primary treatment between Jan/2008 and Mar/2020 at a tertiary referral center. A comprehensive search was made on the MEDLINE primary electronic database. The search strategy was designed to find all articles related to DP-NETs published in the literature. RESULTS: Six patients underwent EP for presenting DP-NETs, four of whom were women (mean age, 63 years). The mean diameter of DP-NETs was 1.6±0.3 cm. Four of six patients were followed up, one of whom suffered relapse at the resection site after 3 months and was referred to surgery (pT3n1b) and the remaining three patients experienced no endoscopic or histological recurrence during follow-up periods of 10, 7, and 4 years, respectively. Eighteen articles were found in the literature search in MEDLINE. The articles included case reports of endoscopically treated DP-NETs. CONCLUSION: EP is safe and effective for DP-NETs that are ≤20 mm, confined to the submucosal layer, well-differentiated, and without local or remote metastasis. Adequate endoscopic follow-up and definitive surgical treatment in the presence of relapse are necessary.
RESUMO CONTEXTO: Tumores neuroendócrinos da papila duodenal (TNE-PD) são raros. A cirurgia deve ser recomendada para o tratamento. No entanto, apresentam altas taxas de morbimortalidade. A papilectomia endoscópica (PE) é segura e eficaz para a ressecção completa de tumores nesta região. OBJETIVO: Descrever uma série de casos de TNEs-PD ressecados por PE e realizar uma revisão da literatura. MÉTODOS: Pacientes com TNEs-PD submetidos a PE como tratamento primário com intenção curativa entre jan/2008 e mar/2020 em um centro de referência terciário foram estudados. Uma pesquisa abrangente foi feita no MEDLINE. A estratégia de busca foi desenhada para encontrar todos os artigos relacionados a TNEs-PD publicados na literatura, que haviam sido submetidos a PE. RESULTADOS: Seis pacientes foram submetidos a PE por apresentar TNEs-PD, sendo quatro mulheres, com média de idade de 66 anos (22-96). O diâmetro médio dos TNEs-PD foi de 1,8±0,4 cm. Quatro dos seis pacientes foram acompanhados, um dos quais sofreu recidiva no local da ressecção após 3 meses e foi encaminhado para cirurgia (pT3n1b), e os três pacientes restantes não apresentaram recorrência endoscópica ou histológica durante os períodos de acompanhamento de 10, 7 e 4 anos, respectivamente. Dezoito artigos foram encontrados no MEDLINE. Os artigos incluíram relatos de casos de TNEs-PD tratados pela PE. CONCLUSÃO: A PE é segura e eficaz para TNEs-PD ≤20 mm, confinados à camada submucosa, bem diferenciados e sem metástases locais ou remotas. Acompanhamento endoscópico adequado e tratamento cirúrgico definitivo na vigência de recidiva são necessários.

Los tumores duodenales son menos frecuentes que los del estómago y colon. Los habituales son los carcinomas, linfomas y tumores de los estromas malignos o benignos; los pólipos duodenales suelen ser asintomáticos. Su manifestación más frecuente es la hemorragia. Las lesiones de gran tamaño pueden cursar con un cuadro suboclusivo y las periampulares producir ictericia. Se presentó el caso de una paciente de 68 años de edad, colecistectomizada que ingresa por íctero intermitente, con episodios de coluria, acolia, prurito generalizado, pérdida de peso y dolor en epigastrio, se realizó ecografía de hígado, vías biliares y páncreas en la cual se evidenció dilatación de vías biliares, se exploró endoscópicamente el duodeno y se observó una lesión sobreelevada se le realizó biopsia, diagnosticándose un adenoma de papila duodenal. La paciente fue sometida a una ampulectomía, no se observó focos de adenocarcinoma en la biopsia quirúrgica y el cuadro ictérico desapareció, no se presentaron complicaciones postoperatorias.
Duodenal tumors are less frequently than those of stomach and colon. The habitual ones are carcinomas, lymphomas and malignant or bening stromal tumors, duodenal polyps are usually asymptomatic. The haemorraghe is the most frequent sign. The great size lesions can show a suboclussive presentation and the periampullary ones can produce. A 68-year-old female patient to whom cholecystectomy was performed was presented in this article. The patient was admitted due to recurrent jaundice, episodes of dark urine, acholia, generalized pruritus, weight loss and epigastric pain. Ultrasonography of the liver, biliary tract and pancreas was performed in which bile duct dilatation was evident, duodenum was also explored and a lesion was observed. Biopsy was done and an adenoma of duodenal papilla was diagnosed. Surgical ampulectomy was performed without adenocarcinoma findings in the surgical biopsy, the jaundice disappeared and none postsurgical complication was observed.
ABSTRACT
Los tumores malignos de la región ampular representan el 1% de todos los carcinomas y el 5% de los carcinomas gastrointestinales. Tienen una mayor incidencia en la 8va década de la vida y son más frecuentes en hombres que en mujeres. Se evaluaron 23 especimenes de gastroduodenopancreatectomía de Whipple por patología tumoral, recibidos en la sección de Patología Quirúrgica del Instituto Anatomopatológico "José A. ODaly" en un lapso comprendido entre los años 2000 y 2005. Todos los tumores fueron epiteliales, y el 92% de los casos fueron tumores malignos.
The malignant tumours of the ampullar region represent 1 % of all carcinomas and 5% of gastrointestinal carcinomas. They generally peak in incidence in the eighth decade of life and they are more frequent in male than female. We evaluated 23 specimens of Whipple´s resection (pancreaticoduodenectomy) for neoplasic pathology, in the surgical pathology section of Anatomopathology Institute Jose ODaly in a period from 2000 to 2005. All tumours were epithelial and 92 % of the cases were malignant tumours.
