ABSTRACT

Resumen Introducción y objetivos: los divertículos duodenales periampulares (DDP) son infrecuentes y su hallazgo es incidental. Además, se clasifican en tres tipos según Boix por la cercanía a la ampolla mayor. El objetivo de este estudio fue realizar una descripción de nuestra experiencia con esta anomalía anatómica y demostrar la forma en que esto afecta la tasa de éxito técnica y terapéutica del procedimiento. Material y métodos: se realizó un estudio de corte transversal, con recolección de datos de forma retrospectiva en un período de 5 años de pacientes con divertículos periampulares duodenales. Se evaluó el fracaso terapéutico, complicaciones y dificultad de canulación de la vía biliar. Resultados: se evaluó un total de 214 pacientes, con una relación mujer-hombre de 2,15:1. La distribución de los sujetos por tipo de DDP fue: tipo 1 (29,9 %), tipo 2 (51,9 %) y tipo 3 (18,2 %). La indicación más frecuente de CPRE fue los cálculos del conducto biliar común en un 53,3 %. El DDP tipo 1 presentó mayor dificultad de canulación (11,6 %) y falla terapéutica (28,12 %). Conclusión: la presencia de DDP durante la CPRE se asocia con una mayor falla técnica (falla en la canulación) y falla terapéutica (persistencia de la obstrucción biliar). Además, estas fallas aumentan considerablemente cuando se trata de una papila intradiverticular tipo 1 de la clasificación según Boix. Por lo anterior, se sugiere que los procedimientos endoscópicos biliares en estas condiciones sean realizados por endoscopistas con gran experiencia con el fin de minimizar la probabilidad de falla técnica y terapéutica, y las complicaciones asociadas.


Abstract Introduction and objectives: Periampullary duodenal diverticula are infrequent, and their finding is incidental. They are classified into three types according to Boix due to their proximity to the larger blister. This study aims to describe the experience with this anatomical abnormality and to demonstrate how this affects the technical and therapeutic success rate of the procedure. Materials y Methods: A cross-sectional study was conducted, with retrospective data collection over a 5-year period of patients with periampullary duodenal diverticula. Therapeutic failure, complications, and difficulty of cannulation of the bile duct were evaluated. Results: A total of 214 patients were evaluated, with a female-male ratio of 2.15: 1. The distribution of the subjects by type of PDD was: type 1 (29.9%), type 2 (51.9%), and type 3 (18.2%). The most frequent indication for ERCP was common bile duct stones in 53.3%. Type 1 PDD presented greater difficulty in cannulation (11.6%) and therapeutic failure (28.12%). Conclusion: The presence of PDD during ERCP is associated with greater technical failure (failure in cannulation) and therapeutic failure (persistence of biliary obstruction). In addition, this failures increases considerably when it is a type 1 intradiverticular papilla of the Boix classification. Therefore, it is suggested that biliary endoscopic procedures in these conditions are performed by highly experienced endoscopists to minimize the probability of technical and therapeutic failure and associated complications.

ABSTRACT

Resumen La hemofilia adquirida A es un desorden hemorrágico inusual de origen autoinmune que resulta en la formación de autoanticuerpos dirigidos contra el factor VIII de la coagulación. Estos autoanticuer pos pueden actuar neutralizando parcial o completamente la activación o función del factor, o también pueden acelerar su eliminación de la circulación. La incidencia mundial de la enfermedad es de 1.5 casos por millón de habitantes por año. En cerca del 50% de los pacientes se puede detectar una enfermedad subyacente que se presume responsable de la producción de los autoanticuerpos. Se presenta el caso de un varón con hemofilia adquirida A, en contexto de adenocarcinoma de la ampolla de Vater.


Abstract Acquired hemophilia A is an unusual bleeding disorder of autoimmune origin resulting in the formation of autoantibodies directed against coagulation factor VIII. These autoantibodies can act by partially or completely neutralizing the activation or function of the factor, or they can also accelerate its elimination from the circulation. The global incidence of the disease is 1.5 cases per million inhabitants per year. In nearly 50% of cases, an underlying disease that is presumed responsible to produce autoantibodies can be detected. We report a case with acquired hemophilia A, in a patient with Vater's ampulla adenocarcinoma.

ABSTRACT

ABSTRACT BACKGROUND: Endoscopic papillectomy has been conceived as a less invasive therapeutic option for treatment of early neoplastic lesions located at the major duodenal papilla. OBJECTIVE: Evaluating patients with early ampullary lesions who underwent curative intent endoscopic papillectomy related to technical success (histopathological tumor margin assessment) and safety (adverse event rate). METHODS: A retrospective study including consecutive patients who underwent curative intent endoscopic papillectomy for demographic, histopathological and pre-/post-procedural clinical assessment. Endpoints were technical success (histopathological residual tumor assessment) and adverse events rates. RESULTS: A total of 21 medical records patients with a female predominance (13 cases, 61.9%) were included. The tumor was incidental in 8 (38%) cases. Negative residual tumor resection margin rate was 72% (15 cases); three of these cases confirmed high-grade dysplasia in the resected specimen, and six cases were invasive neoplasia. Tumoral recurrence was seen in two cases, and median follow-up time was 12 months, with a 23% loss rate (five patients). Six (28.5%) patients had adverse events, all of them early (bleeding and pancreatitis); none of them required surgical intervention and there was no mortality. CONCLUSION: Endoscopic papillectomy allowed for technical successful procedure with complete removal of ampullary neoplastic lesions in the majority of cases with acceptable adverse event rates. Recurrence rate should be carefully assessed in further studies. There was a recent increase in the number of procedures. There was also a low correlation between pre- and post-histopathological assessment regarding the presence of invasive carcinoma and adenoma with high grade dysplasia, with a predominance of superficial neoplastic adenomatous lesions.


RESUMO CONTEXTO: A papilectomia endoscópica tem sido a opção terapêutica menos invasiva no tratamento de tumores precoces que acometem a papila duodenal maior. OBJETIVO: Avaliar pacientes com tumores ampulares precoces submetidos a papilectomia endoscópica com finalidade curativa, com relação ao sucesso técnico (avaliação histopatológica da margem tumoral) e sua segurança (taxa de eventos adversos [EAs]). MÉTODOS: Foram avaliados retrospectivamente dados demográficos, exame histopatológico e evolução clínica pré e pós-procedimento de pacientes consecutivos submetidos a papilectomia endoscópica. Os desfechos avaliados foram o sucesso técnico (avaliação histopatológica de tumor residual) e taxa de EAs. RESULTADOS: Um total de 21 prontuários de pacientes com predominância feminina (13 casos, 61,9%) foi incluído no estudo. O diagnóstico tumoral foi incidental em 8 (38%) casos. A taxa de margem de ressecção negativa foi 72% (15 casos); três destas lesões confirmaram displasia de alto grau (DAG) no espécime ressecado e seis casos de neoplasia invasora. Houve recorrência tumoral em dois casos e a mediana de seguimento foi de 12 meses, com 23% de taxa de perda de seguimento (cinco casos). Seis (28,5%) pacientes apresentaram EAs, todos precoces (hemorragia e pancreatite aguda); nenhum destes necessitou de intervenção cirúrgica e não houve mortalidade. CONCLUSÃO: A papilectomia endoscópica permitiu sucesso técnico, com a completa remoção de lesões neoplásicas ampulares na maioria dos casos com taxa de EAs aceitáveis. A taxa de recorrência tumoral deve ser cuidadosamente avaliada em estudos futuros. Houve um aumento recente do número de procedimentos realizados. Também houve baixa correlação entre o diagnóstico histológico pré e pós-procedimento para a presença de adenocarcinoma invasor e adenoma com DAG, com predomínio de lesões adenomatosas superficiais.

ABSTRACT

Tumores periampulares (TP) são originados a partir de estruturas próximas a Ampola de Vater e correspondem a um grupo heterogêneo de neoplasias. O adenocarcinoma da papila duodenal maior faz parte desse grupo de neoplasias. As principais manifestações são a icterícia do tipo obstrutiva, prurido, colúria, acolia fecal, além de perda ponderal e dor abdominal, associado a elevação dos níveis séricos de bilirrubina e enzimas hepáticas. O prognóstico é obscuro, sendo os carcinomas do tipo pancreaticobiliar aqueles com pior prognóstico. A ecografia endoscópica é o método mais sensível para diagnóstico e estadiamento e o tratamento de escolha é pancreaticoduodenectomia, conhecida como cirurgia de Whipple, frequentemente associada à quimioterapia adjuvante ou terapia de quimiorradiação. O presente trabalho propõe descrever um caso de adenocarcinoma da ampola de Vater em paciente de 38 anos atendida no Hospital Universitário da Universidade Federal de Juiz de Fora (HU-UFJF), abrangendo desde a sintomatologia inicial, processo diagnóstico até a conduta terapêutica. Sua relevância está em alertar os profissionais da saúde sobre a importância de elencar os tumores periampulares entre os possíveis diagnósticos diferenciais para pacientes com síndrome colestática, dado que o diagnóstico e a ressecção cirúrgica precoce são os fatores decisivos para um melhor prognóstico. (AU)


Periampular tumors (PT) originate from structures close to Vater's Ampulla and correspond to a heterogeneous group of cancers. The adenocarcinoma of the major duodenal papilla is part of this group of cancers. The main manifestations are obstructive jaundice, pruritus, choluria, fecal acholia, weight loss and abdominal pain, associated with elevated serum levels of bilirubin and liver enzymes. The prognosis is poor, with pancreaticobiliar type carcinomas having the worst prognosis. Endoscopic ultrasound is the most sensitive method for diagnosis and staging, and the best treatment is pancreaticoduodenectomy, known as Whipple surgery, often associated with adjuvant chemotherapy or chemoradiation therapy. The article proposes to describe a case of adenocarcinoma of the Vater's ampulla in a 38-year-old patient treated at the University Hospital of the Federal University of Juiz de Fora (HU-UFJF), covering from the initial symptoms, the diagnostic process and the therapeutic conduct. Its relevance is to alert health professionals about the importance of listing periampular tumors among the possible differential diagnoses for patients with cholestatic syndrome, considering that the diagnosis and early surgical resection are decisive factors for a better prognosis.

ABSTRACT

Antecedentes: La canulación biliar difícil es un factor de riesgo para la pancreatitis post-CPRE. En estos casos el precorte es la técnica más usada. Objetivo: Demostrar que el precorte tipo fistulotomía es seguro y eficaz. Materiales y métodos: Se revisaron los datos de mayo de 2016 a mayo de 2018. Se definió canulación difícil como: litiasis impactada, canulación inadvertida del conducto pancreático en tres ocasiones e incapacidad para lograr la canulación en 3 minutos. Las medidas de resultados fueron la canulación biliar exitosa y la pancreatitis post-CPRE. Resultados: Se realizó precorte tipo fistulotomía en 96 casos (67 mujeres, 29 hombres). La tasa de éxito de la canulación biliar fue del 95,8% (92/96). Ochenta pacientes tenían factores de riesgo para pancreatitis post CPRE: 29 tuvieron un solo factor de riesgo, 26 tuvieron dos, 19 tuvieron tres y 6 tuvieron cuatro. Factores de riesgo ampulares de canulación difícil: calculo impactado 9 casos, abultamiento de la papila en 10 casos, ubicación inferior del orificio papilar en 38 casos, localización parcial del poro papilar en 23 y estenosis del orificio papilar en 16 casos. Diez pacientes tuvieron divertículo periampular, 7 pacientes tuvieron conducto biliar normal. Ninguno de los pacientes experimentó pancreatitis. Tres pacientes tuvieron sangrado precoz, una paciente presento sangrado tardío. Un paciente (2%) tuvo fiebre y fue hospitalizado. Conclusiones: En casos de canulación biliar difícil el precorte tipo fistulotomía es seguro y eficaz.


Background: Difficult biliary cannulation is a risk factor for post-ERCP pancreatitis. In these cases, precutting is the most used technique. Objective: To demonstrate that precut fistulotomy is safe and effective. Materials and methods: Data from May 2016 to May 2018 were reviewed. Difficult cannulation was defined as: impacted lithiasis, inadvertent cannulation of the pancreatic duct on three occasions and inability to achieve deep biliary cannulation in 3 minutes. The outcome measures were successful biliary cannulation and post-ERCP Pancreatitis. Results: Precut fistulotomy was performed in 96 cases (67 women, 29 men). The success rate of biliary cannulation was 95.8% (92/96). Eighty patients had risk factors for post-ERCP pancreatitis: 29 had 1 risk factor, 26 had 2 risk factors, 19 had 3 risk factors, and 6 had four risk factors. Ampullary risk factors of difficult cannulation: impacted stone in the papilla: 9 cases, papilla bulging: 10 cases, lower location of the hole papillary 38 cases, partial location of the papillary pore 23 and papillary orifice stenosis 16 cases. Ten patients had periampullary diverticulum, 7 patients had normal bile duct. None of the patients experienced Pancreatitis. Three patients had early bleeding, one patient had late bleeding. One patient (2%) had a fever and was hospitalized. Conclusions: In cases of difficult biliary cannulation, the precut fistulotomy is safe and effective.

ABSTRACT

INTRODUCCIÓN: Los carcinomas adenoneuroendocrinos mixtos (MANEC) son tipos de tumores bifásicos, reconocidos morfológicamente ante la presencia de una formación neoplásica constituida de manera simultánea por epitelio glandular y células neuroendocrinas. Dentro del tracto gastrointestinal, estas neoplasias predominan en el estómago o el colon. Solo 19 casos localizados en la ampolla de Vater han sido reportados por la literatura. OBJETIVO: Reportar un caso de MANEC; revisar la epidemiología, pronóstico y tratamiento de estos tumores. MATERIALES Y MÉTODO: Presentación de caso clínico de una paciente con diagnóstico de adenocarcinoma neuroendocrino mixto de la región ampular. DISCUSIÓN: La presentación clínica, el manejo y el pronóstico son similares al del adenocarcinoma ampular. Se diagnostican con el examen histopatológico de la muestra resecada. Ambos componentes deben ser histológicamente malignos, y cada uno de ellos debe representar al menos el 30% de la lesión. CONCLUSIÓN: Los MANEC ampulares son tumores poco comunes a nivel mundial, siendo éste el primer caso reportado en nuestro instituto.


INTRODUCTION: Mixed adenoneuroendocrine carcinomas (MANEC) are types of biphasic tumors, morphologically recognized in the presence of a neoplastic formation constituted simultaneously by glandular epithelium and neuroendocrine cells. Only 19 cases located in the ampulla of Vater have been reported in the literature. Within the gastrointestinal tract, these neoplasms predominate in the stomach or colon. AIM: Report a case of MANEC; review of the epidemiology, prognosis and treatment of these tumors. MATERIALS AND METHOD: Case presentation of a patient diagnosed with mixed adeno-neuroendocrine carcinoma of the ampullary region. DISCUSSION: The clinical presentation, management and prognosis are similar to ampullary adenocarcinoma. These tumors are diagnosed with a histopathological examination of the resected specimen. Both components must be histologically malignant, and each of them must represent at least 30% of the lesion. CONCLUSION: MANEC of the ampulla are rare tumors worldwide, being this case the first reported in our institute.

ABSTRACT

A gangliocytic paraganglioma is a benign tumor of the digestive system with a very low incidence. The tumor is histopathologically characterized by a triphasic pattern consisting of epithelioid, ganglion, and spindle-shaped Schwann cells. In most cases, it occurs in the second portion of the duodenum near the ampulla of Vater. We report a case of a gangliocytic paraganglioma occurring at the minor duodenal papilla (a rare location) with a concurrent adenoma of the ampulla of Vater. Both lesions were treated simultaneously using endoscopic resection. Additionally, we have presented a literature review.

ABSTRACT

BACKGROUND/AIMS: Pathological diagnosis of biliary strictures with atypical or suspicious cells on endoscopic retrograde brush cytology and indeterminate strictures on imaging is challenging. The aim of this study was to identify markers for malignant strictures in such cases. METHODS: We retrospectively analyzed data collected from 146 consecutive patients with indeterminate biliary strictures on imaging who underwent endoscopic retrograde brush cytology from 2007 to 2013. Factors associated with malignant strictures in patients with atypical or suspicious cells on brush cytology were identified. RESULTS: Among the 67 patients with a malignant disease (48 cholangiocarcinoma, 6 gallbladder cancer, 5 pancreatic cancer, 5 ampulla of Vater cancer, and 3 other types), 36 (53.7%) had atypical or suspicious cells on brush cytology. Among these, the factors that independently correlated with malignant strictures were stricture length (odds ratio [OR], 5.259; 95% confidence interval [CI], 1.802– 15.294) and elevated carbohydrate antigen 19-9 (CA19-9) (OR, 3.492; 95% CI, 1.242–9.815), carcinoembryonic antigen (CEA) (OR, 4.909; 95% CI, 1.694–14.224), alkaline phosphatase (ALP) (OR, 3.362; 95% CI, 1.207–9.361), and gamma-glutamyl transpeptidase (rGT) (OR, 4.318; 95% CI, 1.512–12.262). CONCLUSIONS: Elevated levels of CA19-9, CEA, ALP, and rGT and stricture length are associated with malignant strictures in patients with indeterminate biliary strictures on imaging and atypical or suspicious cells on brush cytology.

ABSTRACT

The pancreatoduodenal groove is a small area where pathologic processes involving the distal bile duct, duodenum, pancreatic head, ampulla of Vater, and retroperitoneum converge. Despite great advances in imaging techniques, a definitive preoperative diagnosis is challenging because of the complex anatomy of this area. Therefore, surgical intervention is frequently required because of the inability to completely exclude malignancy. We report 3 cases of patients with different groove pathologies but similar clinical and imaging presentation, and show the essential role of endoscopic ultrasound (EUS) in making a specific preoperative diagnosis, excluding malignancy in the first case, changing diagnosis in the second case, and confirming malignancy in the third case. EUS was a fundamental tool in this cohort of patients, not only because of its ability to provide superior visualization of a difficult anatomical region, but because of the ability to guide precise, real-time procedures, such as fine-needle aspiration.

ABSTRACT

Endoscopic retrograde cholangiopancreatography (ERCP) of the intradiverticular papilla with its invisible orifice remains challenging. Several techniques have been introduced to evert the papillary opening to facilitate cannulation. A 79-year-old woman with bile duct stones underwent ERCP, which revealed that the papilla was located inside a large diverticulum and tended to rotate inward with a trial of papillary cannulation. Submucosal papillary injection of 3 cc of normal saline was performed at 3 and 9 o’clock. Eversion and fixation of a papilla in the diverticulum with this technique allowed selective cannulation of the biliary tree. Stones were retrieved after endoscopic papillary balloon dilation without complications. She had an uneventful post-procedural course. Our findings suggest that submucosal saline injection technique is safe and effective for selective cannulation and can be recommended when cannulation is very difficult because of an intradiverticular papilla.

ABSTRACT

Endoscopic sphincterotomy is performed after selective cannulation to remove the gallstone. Endoscopic sphincterotomy can cause complications such as bleeding, perforation and pancreatitis. Various types of endoscopic sphincter incision method and current generators used for incisions have been developed to reduce the incidence of such complications and increase the success rate of the procedure. In addition, guidelines for the direction and extent of endoscopic sphincterotomy and incision technique are established. The method used for the removal of gallstones after the endoscopic sphincterotomy is a method using a balloon and/or a basket. This review introduces the technical methods of endoscopic sphincterotomy and discusses the clinical indications and technical methods for representative methods of effective gallstone removal.

ABSTRACT

PURPOSE: The prognosis of periampullary cancer varies with its origin and early diagnosis influences outcome. Endoscopic ultrasound, computed tomography, fine needle aspiration, and fluorodeoxyglucose-positron emission tomography/computed tomography (¹⁸FDG-PET/CT) are helpful for diagnosis. This study evaluates the diagnostic efficacy of ¹⁸FDG-PET for preoperative periampullary tumors.METHODS: A series of 100 patients undergoing ¹⁸FDG-PET/CT before surgical resection of periampullary tumors between March 2011 and February 2019 were enrolled. Maximum standardized uptake value (SUVmax) and carbohydrate antigen 19-9 (CA19-9) levels were compared with pathohistological confirmation of periampullary tumors.RESULTS: The SUVmax and uptake range varied with the origin of the periampullary tumors. The SUVmax was not available for 17 of the 42 pancreas tumors, three of 30 common bile duct tumors, and four of 18 ampulla of Vater tumors. The median SUVmax was 0.0 in benign tumors and 5.05 in malignant tumors. The mean SUVmax was 4.1±5.6 in pancreatic tumors, 3.9±2.4 in ampulla of Vater, and 6.0±3.7 in common bile duct. The SUVmax was higher in common bile duct tumors than others. CA19-9 level was of diagnostic value in pancreatic tumor patients. The median CA19-9 levels were 7.64 U/mL (range, 2.71–45.05 U/mL) in benign tumors and 91.97 U/mL (range, 26.91–276.60 U/mL) in cancers patients.CONCLUSION: Preoperative SUVmax and CA19-9 level were of diagnostic value for periampullary tumors originating in the pancreas.

ABSTRACT

Se presenta el primer caso de cirugía de Whipple realizada en el Hospital Regional de Tumbes para tratamiento de ampuloma con resultado exitoso. Reporte de caso de una paciente con diagnóstico de ampuloma en la que se realizó la primera cirugía de Whipple efectuada en el Hospital Regional de Tumbes en octubre del año 2014. La paciente con diagnóstico de síndrome ictérico obstructivo por ampuloma fue sometida a cirugía de Whipple, cursó el post operatorio con mejoría paulatina, no presentó patología respiratoria, ni cursó con fiebre, la paciente toleró la vía oral, la ictericia disminuyó y fue dada de alta hospitalaria a los 13 días. Cursó con fístula pancreática de gasto bajo (30 cc/día) la cual remitió a las 3 semanas. La paciente presentó mejoría clínica evidente y con resultados quirúrgicos satisfactorios hasta la fecha. La cirugía de Whipple es la técnica quirúrgica de elección en el tratamiento del ampuloma y es factible de realizarse, en casos que lo ameriten, en hospitales de frontera si se cuenta con el personal capacitado y la logística necesaria.


To report the first case of Whipple surgery performed at the Regional Hospital of Tumbes for the treatment of ampullary adenocarcinoma with successful results. A case report of a patient with diagnosis of ampullary adenocarcinoma, in whom was performed the first Whipple surgery at the Regional Hospital of Tumbes, in October, 2014. The patient diagnosed with an obstructive jaundice syndrome due to ampullary adenocarcinoma underwent Whipple surgery. She performed the postoperative period with gradual improvement, she did not present with respiratory pathology, she not have fever, the patient tolerated the oral route, the jaundice decreased and she was discharged after 13 days. She presented low-output pancreatic fistula (30 cc/day), which remitted at 3 weeks. The patient presented evident clinical improvement and satisfactory surgical results to date. Whipple surgery is the surgical technique of choice in the treatment of the ampullary adenocarcinoma and it is feasible to perform, in cases that is indicated, in bounderies hospitals if you have the trained personnel and necessary logistics.

ABSTRACT

ABSTRACT BACKGROUND: - Conventional esophagogastroduodenoscopy is the best method for evaluation of the upper gastrointestinal tract, but it has limitations for the identification of the major duodenal papilla, even after the use of the straightening maneuver. Side-viewing duodenoscope is recommended for optimal examination of major duodenal papilla in patients at high risk for lesions in this region. OBJECTIVE: To evaluate the use of the biopsy forceps during conventional esophagogastroduodenoscopy as an additional tool to the straightening maneuver, in the evaluation of the major duodenal papilla. METHODS: A total of 671 patients were studied between 2013 and 2015, with active major duodenal papilla search in three endoscope steps: not straightened, straightened and use of the biopsy forceps after straightening. In all of them it was recorded whether: major duodenal papilla was fully visualized (position A), partially visualized (position B) or not visualized (position C). If major duodenal papilla was not fully visualized, patients continued to the next step. RESULTS: A total of 341 were female (50.8%) with mean age of 49 years. Of the 671 patients, 324 (48.3%) major duodenal papilla was identified in position A, 112 (16.7%) in position B and 235 (35%) in position C. In the 347 patients who underwent the straightening maneuver, position A was found in 186 (53.6%), position B in 51 (14.7%) and position C in 110 (31.7%). Of the 161 remaining patients and after biopsy forceps use, position A was seen in 94 (58.4%), position B in 14 (8.7%) and position C in 53 (32.9%). The overall rate of complete visualization of major duodenal papilla was 90%. CONCLUSION: The use of the biopsy forceps significantly increased the total major duodenal papilla visualization rate by 14%, reaching 604/671 (90%) of the patients (P<0.01) and it can be easily incorporated into the routine endoscopic examination of the upper gastrointestinal tract.


RESUMO CONTEXTO: Esofagogastroduodenoscopia convencional é o melhor método para avaliação do trato gastrointestinal superior, mas apresenta limitações para identificação da papila duodenal maior, mesmo após emprego da manobra de retificação. Exame completo da papila duodenal maior está indicado para pacientes de alto risco para adenocarcinoma da papila duodenal maior. OBJETIVO: Avaliar a utilização da pinça de biópsia durante esofagogastroduodenoscopia convencional como ferramenta adicional à manobra de retificação na avaliação da papila duodenal maior. MÉTODOS: Foram estudados 671 pacientes entre 2013-2015 com busca ativa da papila duodenal maior em três etapas: endoscópio não retificado, endoscópio retificado e uso da pinça de biópsia após retificação. Em todas se registrou: se a papila duodenal maior foi totalmente visualizada (posição A), se parcialmente visualizada (posição B) ou se não visualizada (posição C). Caso a papila duodenal maior não tenha sido completamente visualizada, o paciente foi direcionado para a etapa seguinte. RESULTADOS: Um total de 341 era do sexo feminino (50,8%) com idade média de 49 anos. Dos 671 pacientes, em 324 (48,3%) a papila duodenal maior foi identificada na posição A, 112 (16,7%) em posição B e, 235 (35%) em posição C. Dos 347 pacientes submetidos à manobra de retificação, posição A foi encontrada em 186 (53,6%), posição B em 51 (14,7%) e posição C em 110 (31,7%). Dos 161 pacientes restantes que utilizaram a pinça de biópsia, posição A foi vista em 94 (58,4%), posição B em 14 (8,7%) e posição C em 53 (32,9%). A taxa acumulativa de visualização completa da papila duodenal maior foi de 90%. CONCLUSÃO: O uso da pinça de biópsia aumentou a taxa de visualização completa da papila duodenal maior em 14%, alcançando 604/671 (90%) dos pacientes (P<0,01) avaliados e pode ser facilmente incorporada aos exames endoscópicos de rotina do trato gastrointestinal superior.

ABSTRACT

A 43-year-old male was admitted to our hospital via emergency room with epigastric pain for 3 days. Abdominal computed tomography revealed pneumobilia in the biliary tree. Endoscopic retrograde cholangiopancreatography showed an atypical location of ampulla of Vater (AOV) with duodenal deformity. The plastic stent was placed through the fistular opening at the upper mound of AOV for biliary decompression. He was rehospitalized due to aggravation of jaundice two weeks later. The previous stent was changed into the nasobiliary catheter and biopsy was done around the ectopic opening. He underwent Whipple's operation due to the high grade dysplasia on biopsy. This is the report of aberrant opening of the common bile duct (CBD) into the duodenal bulb with precancerous conditions. Therefore, endoscopic biopsy is recommended in patients with mucosal abnormality around the ectopic opening of the CBD.

ABSTRACT

An ampulla of Vater neuroendocrine tumor (AOV-NET) is a rare subset of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Very few studies have been undertaken regarding MRI findings of an AOV-NET. We report on a case of a 59-year-old woman diagnosed with an AOV-NET with liver and lymph node metastasis, with an emphasis on the MRI findings. This case shows rare and precious typical MRI findings of an AOV-NET. The MRI visualized the AOV-NET very well and is helpful for the differentiation of an AOV-NET from other tumors in the ampullary area as well as with treatment planning.

ABSTRACT

Neuroendocrine tumor (NET) of the major duodenal papilla is a rare occurrence. However, that of the minor duodenal papilla is even rarer. To date, only a few cases have been reported. Herein, we present a rare case of NETs detected at the major and minor duodenal papilla synchronously, which were successfully treated with endoscopic papillectomy without procedure-related complication. To the best of our knowledge, this is the first report of this kind in the world. Photomicrograph of the biopsy specimen stained immunohistochemically for synaptophysin showed a positive reaction of tumor cells. All resection margins were negative. Further experience with more cases will be needed to establish the exact indication of endoscopic papillectomy for duodenal papillary NETs.

ABSTRACT

PURPOSE: Transduodenal ampullectomy (TDA) has been reported in a limited number of cases and in a small number of case series. The aim of this study was to analyze perioperative and long-term oncological outcomes of patients with ampullary tumors who underwent TDA in a single large-volume center. METHODS: Through a retrospective review of data from 2004 to 2016, we identified 26 patients who underwent TDA at Asan Medical Center. RESULTS: Eleven of 26 patients underwent TDA for T1 and carcinoma in situ (high-grade dysplasia) cancer; these patients are still alive without recurrence. A major in-hospital complication (3.8%) occurred in 1 case, but there was no case of 90-day mortality. In addition, none of the patients was diagnosed as having newly developed diabetes mellitus after TDA. No significant differences were found between open and laparoscopic-TDA in terms of operation time, painkiller use, and hospital stay. CONCLUSION: TDA is a feasible and effective surgical procedure for the treatment of selected patients with ampullary tumors. It is an alternative treatment option in cases of ampullary tumors not amenable to endoscopic papillectomy or pancreaticoduodenectomy.

ABSTRACT

ABSTRACT Introduction: Periampular neoplasms represent 5% of all cancers of the gastrointestinal tract with peak incidence in the 7th decade of life. The most common clinical picture is jaundice, weight loss and abdominal pain. Considering that cholestasis is related to postoperative complications, preoperative biliary drainage was developed to improve the postoperative morbidity and mortality of icteric patients with periampular neoplasias, whether resectable or not. Objective: To describe the outcome of patients with periampullary tumors undergoing preoperative biliary drainage with pancreatoduodenectomy. Method: The search was performed in the Medline/PubMed and Virtual Health Library databases by means of the combination of descriptors of the Medical Subject Headings. Inclusion criteria were clinical trials, cohorts, studies that analyze the morbidity and mortality of preoperative biliary drainage in Portuguese, English and Spanish. Exclusion criteria were studies published more than 10 years ago, experimental studies, systematic reviews and articles with WebQualis C or smaller journal in the area of ​​Medicine I or Medicine III. Of the 196 references found, 46 were obtained for reading with quality assessed through the Checklist Strengthening the Reporting of Observational Studies in Epidemiology. Eight studies were selected for review. Results: A total of 1116 patients with a sample ranging from 48 to 280 patients and a mean age of 48 to 69 years were obtained. Of the eight studies, four observed a higher rate of bleeding in drained patients; three a higher rate of positive bile culture in the intervention group; site and cavitary infection, and biliopancreatic leaks were more common in the drainage group in two studies each. The death outcome and rate of reoperation were observed in larger numbers in the control group in one study each. Conclusion: Preoperative intervention leads to a higher rate of infectious complications and bleeding.


RESUMO Introdução : Neoplasias periampulares representam 5% de todos os cânceres do trato gastrointestinal com pico de incidência na sétima década de vida. O quadro clínico mais comum é icterícia, perda de peso e dor abdominal. Considerando que a colestase está relacionada às complicações pós-cirúrgicas, a drenagem biliar pré-operatória foi desenvolvida objetivando melhorar a morbimortalidade pós-operatória de pacientes ictéricos com neoplasias periampulares, sejam elas ressecáveis ou não. Objetivo : Descrever o desfecho de pacientes com tumores periampulares submetidos à pancreatoduodenectomia com drenagem biliar pré-operatória. Método : A busca foi realizada nas bases de dados Medline/PubMed e Biblioteca Virtual em Saúde por meio da combinação de descritores do Medical Subject Headings. Os critérios de inclusão foram ensaios clínicos, coortes, estudos que analisam a morbimortalidade da drenagem biliar pré-operatória em português, inglês e espanhol. Os critérios de exclusão foram estudos publicados há mais de 10 anos, estudos experimentais, revisões sistemáticas e artigos com revista WebQualis C ou menor na área de Medicina I ou Medicina III. Das 196 referências encontradas, 46 foram obtidas para a leitura com qualidade avaliada através do checklist Strengthening the Reporting of Observational Studies in Epidemiology. Oito estudos foram selecionados para a revisão. Resultados : Obteve-se 1116 pacientes com variação de amostra de 48 a 280 pacientes e média de idade de 48 a 69 anos. Dos oito estudos, quatro observaram maior taxa de sangramento em pacientes drenados; três maior taxa de cultura de bile positiva no grupo intervenção; infecção de sítio e cavitária, além de vazamentos biliopancreáticos foram mais comuns no grupo da drenagem em dois estudos cada. O desfecho morte e a taxa de reoperação foram observados em maior quantidade no grupo controle em um estudo cada. Conclusão : A intervenção pré-operatória leva a maior taxa de complicações infecciosas e sangramentos.

ABSTRACT

Objetivo: Describir las características clínicas y tomográficas en relación a la distribución extra peritoneal de colecciones y aire seguida de perforación periampular luego de la realización de colangiopancreatografía retrograda endoscópica (CPRE) con o sin esfinterotomía. Materiales y métodos: Estudio observacional, descriptivo y transversal, en pacientes con perforación periampular, después de CPRE con o sin enfinterotomía, tratados en el Servicio de Cirugía de Páncreas del Hospital Edgardo Rebagliati Martins, Lima, Perú, entre enero del 2013 y enero del 2015. Resultados: Se incluyeron 10 pacientes con perforación periampular, después CPRE. El 40% fue de sexo masculino. La edad media fue de 47,2 años. El 100% presento dolor abdominal, el 70% fiebre, el 60% presentó ictericia, intolerancia oral y vómitos. En el 100% de los casos la indicación del procedimiento fue por litiasis coledociana. Se describe canulación difícil en el 80% de los casos. Se encontró aire o líquido en el 90% en los espacios pararrenal anterior derecho y el perirrenal derecho, y el lugar en donde se distribuyó el aire o liquido con menor frecuencia fue la pelvis extra peritoneal derecha con el 20%, en ningún caso se evidenció aire en el mediastino. Conclusiones: El hallazgo de una colección líquida y/o aire en el espacio retroperitoneal derecho, después de CPRE, sin mayor afección de la glándula pancreática, debe hacernos pensar en perforación periampular, sobre todo si se encuentra en el espacio pararrenal anterior derecho y el espacio perirrenal derecho. A esta entidad nosotros la hemos denominado bilioretroperitoneo.


Objective: Describe the clinical and tomographic characteristics in relation to the extra peritoneal distribution of collections and air in patients with periampullary perforation after performing endoscopic retrograde cholangiopancreatography (ERCP) with or without sphincterotomy. Materials and methods: Observational, descriptive study in patients with periampullary perforation after ERCP with or without sphincterotomy, treated in the Pancreas Surgery Service at Edgardo Rebagliati Martins Hospital, Lima, Peru between January 2013 and January 2015. Results: Ten patients with periampullary perforation after ERCP were included. 40% were male. The mean age was 47.2 years. 100% showed abdominal pain, fever 70%, 60% had jaundice, oral intolerance and vomiting. In 100% of cases the description of the procedure was for choledocolithiasis. Difficult cannulation is described in 80% of cases. Air or fluid was found in 90% in the right anterior pararenal space and the right perirenal, and the place where air or liquid is distributed less frequently was right extraperitoneal pelvis with 20%, in no case revealed air in the mediastinum. Conclusions: The finding of a liquid collection and / or air in the retroperitoneal space right after ERCP without further involvement of the pancreatic gland should make us think of periampullary perforation, especially if you are in the right anterior pararenal space and perirenal space. This entity we call bilioretroperitoneo.
