INTRODUCTION: Underwater endoscopic mucosal resection (UEMR) and cold snare polypectomy (CSP) are novel endoscopic procedures for superficial nonampullary duodenal epithelial tumors (SNADET). However, consensus on how to use both procedures appropriately has not been established. In this study, we evaluated treatment outcomes of both procedures, including resectability. METHODS: In this single-center randomized controlled study conducted between January 2020 and June 2022, patients with SNADET ≤12 mm were randomly allocated to UEMR and CSP groups. The primary end point was sufficient vertical R0 resection (SVR0), which was defined as R0 resection including a sufficient submucosal layer. We compared treatment outcomes including SVR0 rate between groups. RESULTS: The SVR0 rate was significantly higher in the UEMR group than in the CSP group (65.6% vs 41.5%, P = 0.01). By contrast, the R0 resection rate was not significantly different between study groups (70.3% vs 61.5%, P = 0.29). The submucosal layer thickness was significantly greater in the UEMR group than in the CSP group (median 546 [range, 309-833] µm vs 69 [0-295] µm, P < 0.01). CSP had a shorter total procedure time (median 12 [range, 8-16] min vs 1 [1-3] min, P < 0.01) and fewer total bleeding events (9.4% vs 1.5%, P = 0.06). DISCUSSION: UEMR has superior vertical resectability compared with CSP, but CSP has a shorter procedure time and fewer bleeding events. Although CSP is preferable for most small SNADET, UEMR should be selected for lesions that cannot be definitively diagnosed as mucosal low-grade neoplasias.

Introducción: El Síndrome de la Arteria Mesentérica Superior es causa poco frecuente de obstrucción duodenal. Los síntomas varían desde una obstrucción leve hasta emergencias agudas. El examen físico no siempre ayuda al diagnóstico, que se basa en los hallazgos imagenológicos. Objetivo: preconizar, recomendar el uso de las técnicas mínimamente invasivas en el manejo quirúrgico del Síndrome de la Arteria Mesentérica Superior. Presentación del caso: Mujer de 49 años de edad, antecedentes de pérdida de peso después de quimioterapia con náuseas, vómitos y dolor abdominal posprandial de dos años de evolución. Tratada exitosamente con duodenoyeyunostomía laparoscópica. El tratamiento inicial suele ser conservador. Publicaciones recientes respaldan que la duodenoyeyunostomía laparoscópica es un método seguro y efectivo para su tratamiento. Conclusiones: El tratamiento quirúrgico es cada vez más exitoso, la mayoría de los pacientes no presenta síntomas después de la cirugía(AU)
Introduction: Superior Mesenteric Artery Syndrome is an uncommon cause of duodenal obstruction. Symptoms may vary from mild obstruction to acute life-threatening emergencies. Physical examination does not always help in establishing the diagnosis which is based on findings from imaging studies. Objective: To recommend the laparoscopic approach for the surgical treatment of this entity. Case presentation: A 49-year old female patient with prior history of weight loss after chemotherapy and a two-year history of postprandial nausea, vomiting, and abdominal pain who was successfully treated by laparoscopic duodenojejunostomy is presented. Discussion: Initial treatment is usually conservative. Recently published studies support that laparoscopic duodenojejunostomy is a safe and effective method of treatment. Conclusions: Surgical treatment is becoming more successful and the majority of patients are symptom-free after surgery(AU)

Introducción: El uraco o conducto onfalomesentérico es una estructura embrionaria que conecta el intestino medio y el saco vitelino, que involuciona antes del tercer trimestre de embarazo. Objetivo: Presentar un caso con diagnóstico de adenocarcinoma uracal, neoplasia maligna rara. Desarrollo: Paciente de 50 años de edad sin antecedentes patológicos, con cuadro clínico inicial de ascitis y dolor abdominal, al examen físico masa palpable en hipocondrio-fosa iliaca izquierda que en la tomografía abdominal se observa una masa adyacente a la cúpula vesical y pared anterior del abdomen. El resultado de la biopsia reportó un adenocarcinoma mucinoso del conducto onfalomesentérico (uracal). Al momento del diagnóstico, el paciente se encontró en un estadio IVB según el sistema Sheldon y otros y un IV según sistema Mayo, etapa avanzada de la enfermedad que determina mal pronóstico. Se instauró tratamiento con quimioterapia neoadyuvante, quirúrgico y continuación con quimioterapia adyuvante, el cual continúa, actualmente, con una evolución estable. Conclusiones: Esta es una neoplasia rara. Sospechar su diagnóstico llevará a un diagnóstico temprano, lo que mejorará el pronóstico y sobrevida de los pacientes afectados(AU)
Introduction: The urachus or omphalomesenteric duct is an embryonic structure connecting the midgut and the yolk sac, which regresses before the third trimester of pregnancy. Objective: To report a case with a diagnosis of urachal adenocarcinoma, a rare malignant neoplasm. Case report: A 50-year-old patient with no pathological history, who had an initial clinical condition of ascites and abdominal pain. At physical examination, we found a palpable mass in the left hypochondrium - iliac fossa, which revealed a mass next to the bladder dome and anterior wall on the abdominal tomography of the abdomen. The biopsy result reported a mucinous adenocarcinoma of the omphalomesenteric duct (urachal). At the time of diagnosis, the patient was in stage IVB according to the Sheldon et al system and IV according to the Mayo system, an advanced stage of the disease that determines poor prognosis. Treatment with neoadjuvant and surgical chemotherapy was established and adjuvant chemotherapy to follow, which currently continues with a stable evolution. Conclusions: This is a rare neoplasm. Suspecting its diagnosis will lead to an early diagnosis, which will improve the prognosis and survival of affected patients(AU)

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.

Resumen Durante 11 años un varón de 38 años de edad, residente en una región subtropical de Ecuador, había sido diagnosticado de anemia crónica y tratado con transfusiones de sangre en un hospital de la provincia de Cotopaxi, Ecuador. Fue transferido a Quito por una anemia grave, con hemoglobina de 4 g/dL. Se realizó una duodenoscopia en que se observaron nemátodos adultos, identificados posteriormente como Ancylostoma duodenale. El paciente fue tratado exitosamente con albendazol durante cinco días consecutivos y transfusiones de sangre. En el seguimiento a los ocho meses, no se encontró anemia ni huevos de anquilostomas en el examen de heces.
For 11 years, a 38-year-old male residing in a subtropical region of Ecuador, was repeatedly diagnosed with chronic anemia, and treated with blood transfusions in a hospital of province of Cotopaxi, Ecuador. He was transferred to Quito for severe anemia, having hemoglobin of 4 g/dL. Duodenoscopy was performed and adult nematodes, identified later as Ancylostoma duodenale, were observed. The patient was successfully treated with albendazole for five consecutive days and given blood transfusions. In the control visit at eight months, without anemia and no hookworm ova in the stool examined were found.

La colangiopancreatografía retrógrada endoscópica (CPRE) se considera el tratamiento de primera línea para el drenaje biliar en pacientes con cáncer de páncreas. En los casos de fracaso por CPRE, generalmente se realiza un drenaje biliar transparietohepático o una derivación biliar quirúrgica. En la última década, las indicaciones y la utilidad de la ecoendoscopia en pacientes con cáncer de páncreas han ido creciendo, y se han informado numerosos casos de drenajes biliares guiados por ecoendoscopia como una alternativa al drenaje biliar percutáneo o quirúrgico en fracasos en la CPRE. Nuestro objetivo es comunicar un caso con cáncer de páncreas localmente avanzado que se presentó con ictericia indolora y síndrome coledociano con obstrucción biliar y duodenal, en el que se realizó una colédoco-duodenostomía guiada por ecoendoscopia mediante la colocación de una prótesis metálica autoexpandible.
Endoscopic retrograde cholangiopancreatography (ERCP) is considered the first-approach for biliary drainage. In cases of ERCP failure, patients are usually referred for percutaneous transhepatic biliary drainage or surgical biliary bypass. In the last decade, the indications of endoscopic ultrasound (EUS) in the management of patients with pancreatic cancer have increased, and numerous cases of EUS-guided biliary drainage have been reported in patients with failures during the ERCP. Our goal is to report a patient with locally advanced pancreatic cancer who presented with painless jaundice and cholestasis with biliary and duodenal obstruction. A EUS-guided choledochoduodenostomy was performed by placement of a self-expanding metal stent.

We report herein improved methods for the safe and successful completion of endoscopic papillectomy (EP). Between January 2008 and November 2011, 12 patients underwent double-snare retracting papillectomy for the treatment of lesions of the major duodenal papilla. The main outcomes were en bloc resection rates, pathological findings, and adverse events. All of the patients (mean age, 60.1 years; range, 38 to 80 years) were diagnosed with ampullary adenoma by endoscopic forceps biopsies prior to endoscopic snare papillectomy. En bloc resection by double-snare retracting papillectomy was successfully performed for all lesions (median size, 12.3 mm), comprising six tubular adenomas, one tubulovillous adenoma, three cases of epithelial atypia, one hamartomatous polyp, and one case of duodenitis with regenerative change. Significant hemorrhage and pancreatitis were observed in one case after EP. Adenoma recurrence occurred in three patients during follow-up (median, 28.5 months) at a mean interval of 2 months postoperatively (range, 1 to 3 months). No serious adverse events were observed. Double-snare retracting papillectomy is effective and feasible for treating lesions of the major duodenal papilla. Further treatment experience, including a single-arm phase II study, needs to be accumulated before conducting a randomized controlled study.

INTRODUCTION: We used the immersion technique for the evaluation of duodenal mucosa for several years and we observed discordant results in relation to the literature. OBJECTIVE: To evaluate the immersion technique in the diagnosis of duodenal mucosa diseases. PATIENTS AND METHOD: We performed an upper endoscopy, immersion technique, chromoendoscopy and biopsies of the second portion of the duodenum to the patients who met the inclusion criteria. It was reported the presence of villi and the partial or total absence of them. RESULTS: The standard endoscopy showed absence of villi in 16 patients and normal mucosa in 384. The comparison between these results and those of the biopsies showed that biopsies were normal in 3 patients with presumed absence of villi and had a partial atrophy of villi in 1 patient with normal endoscopy. With the immersion technique and the chromoendoscopy we observed absence of villi in 13 patients and normal mucosa in 386. When we compared these results with those of the biopsies, we observed that 1 normal patient had a partial atrophy of villi. These results indicate that standard endoscopy has a sensitivity of 92
, a specificity of 99
, a positive predictive value of 81
and a negative predictive value of 99
. The immersion technique and chromoendoscopy have a sensitivity of 92
, a specificity of 100
, a positive predictive value of 100
and a negative predictive value of 99
. CONCLUSION: In our experience the immersion technique does not improve the visualization of the villi compared with the standard endoscopy and the chromoendoscopy.
