ABSTRACT
BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) is the preferred technique for treating early gastric cancer (EGC). However, very few studies have been conducted in South America. This study aimed to assess the efficacy and safety of ESD for EGC. METHODS: We analyzed data from a prospective cohort from 2013 to 2020. A total of 152 superficial gastric neoplasms that fulfilled the absolute or expanded criteria for ESD were included. Outcomes were en bloc, R0, and curative resection rates, incidence of adverse events, and length of procedure. RESULTS: The age of the enrolled patients was 68.4±11.3 years. The number of included patients based on the absolute and expanded indications was 150 and 2, respectively. En bloc, R0, and curative resections were achieved in 98.0%, 96.1%, and 89.5% of the cases, respectively. Bleeding and perforation were reported in 5.9% and 6.6% of the cases, respectively. Histopathological examination revealed lowgrade dysplasia, high-grade dysplasia, well-differentiated adenocarcinoma, and poorly differentiated adenocarcinoma in 13, 20, 117, and 2 cases, respectively. CONCLUSION: Our study shows that ESD performed by properly trained endoscopists in reference centers is safe and effective, with comparable therapeutic outcomes to those reported in the Eastern series.
ABSTRACT
A 15-year-old male patient presented with dysphagia, regurgitation, weight loss and retrosternal pain. The diagnosis of achalasia was made 4 years before. The esophagogram revealed severe esophagus dilatation and the classic "bird-beak" termination. A Heller myotomy plus fundoplication and endoscopic balloon dilatation were conducted four months previously. Nevertheless, the symptoms persisted and the last high-resolution manometry study still showed achalasia type II. The patient underwent a peroral endoscopic esophageal myotomy (POEM). POEM is a feasible and safe procedure for experienced and properly-equipped health care delivery centers and could be used as a rescue treatment in refractory achalasia. We present the youngest patient with achalasia in our region who had a successful response to rescue POEM.

Un paciente varón de 15 años, con el diagnóstico de acalasia realizado 4 años antes, acudió a evaluación por presentar disfagia, regurgitación, pérdida de peso y dolor restroesternal. El esofagograma baritado evidenció una dilatación severa del esófago y la terminación clásica en "pico de pájaro". El paciente había sido sometido a una miotomía de Heller más fundoplicatura y posteriormente a una dilatación esofágica con balón 4 meses atrás. Sin embargo, los síntomas persistían y la última manometría de alta resolución reveló acalasia tipo II. Finalmente, se realizó una miotomía endoscópica por vía oral (POEM); el cual es un procedimiento seguro y accesible en centros experimentados y debidamente equipados, pudiendo ser una adecuada opción de tratamiento en casos de acalasia refractaria. Presentamos el caso del paciente más joven en nuestra región con acalasia con una respuesta exitosa a un POEM de rescate.
ABSTRACT
INTRODUCTION: colorectal perforations are one of the most feared complications after performing an endoscopic resection. The use of endoclips is considered for the management of these complications. OBJECTIVES: to evaluate the efficacy and safety of the use of endoclips in the management of perforations and deep mural injuries that occur after an endoscopic colorectal resection. METHODS: a prospective cohort of consecutively included patients was used with a diagnosis of perforation or deep mural injury after an endoscopic colorectal resection treated with endoclips in our institution. The rates of perforation and deep mural injury were obtained. The factors associated with an unfavorable evolution after the placement of the endoclips were analyzed. RESULTS: after 342 endoscopic mucosal resections (EMR) and 42 endoscopic submucosal dissections (ESD), there were 25 cases with perforation or deep mural injury. The deep mural injury rate was 3.22 % and 7.14 % in the case of EMR and ESD, respectively. The perforation rate was 1.46 % and 14.29 % in the case of EMR and ESD, respectively. Successful closure with endoclips was achieved in 24 cases (96 %). Only one patient presented an unfavorable evolution (10 %) after successful closure. The factors associated with an unfavorable evolution were the presence of diffuse peritoneal symptoms and a perforation size greater than or equal to 10 mm. CONCLUSION: endoscopic closure with endoclips is effective to avoid surgery in cases of deep mural injury or perforation after an endoscopic resection

Duodenal type follicular lymphoma is a rare malignancy accounting for less than 4% of primary non-Hodgkin lymphomas of the gastrointestinal tract and it is a new entity that was recently described in the new update WHO 2016. Data regarding long-term outcome are currently lacking, and for that reason, a consensus on the management of this disease has not been established and treatment. We report a case of a 57-year-old female patient diagnosed with duodenal- type follicular lymphoma grade 3a who was treated with R-CHOP. The aim of this study is to add more data for a greater characterization of the entity and thus select the best management for each case.

BACKGROUND: In recent years there has been an increase in the use of self-expanding metallic stents (SEMS) in patients with unresectable malignant stenosis of the bile duct. However, in Peru there are no reports on the safety and efficacy of this procedure. OBJECTIVE: To evaluate the safety and efficacy of the use of SEMS in the palliative management of malignant stenosis of the bile duct. MATERIALS AND METHODS: Retrospective cohort. All patients referred for placement of biliary SEMS as part of a palliative treatment between January 2016 and August 2018 were included. Rates of successful placement of SEMS, adequate palliation of the obstruction, and complications associated with the procedure were obtained. The patency of the prosthesis was evaluated during follow-up. Survival was determined after placement of the prosthesis. RESULTS: We included 32 patients with indication of palliative management due to an unresectable malignant stenosis of the bile duct. Pancreatic cancer (56.25%) followed by cholangiocarcinoma (31.25%) were the most frequent etiologies. A successful first-time placement rate of 96.97% was achieved. Adequate palliation of biliary obstruction was achieved in 100% of patients (p<0.05). Two SEMStc migrated during follow-up (6.25%) being managed with the placement of a new SEMSuc. CONCLUSIONS: The placement of SEMS is a safe and effective therapeutic strategy in the palliative management of patients with malignant obstruction of the biliary tract.

Antecedentes: En los últimos años se ha producido un incremento del uso de prótesis metálicas autoexpandibles (SEMS) en pacientes con estenosis malignas irresecables de la vía biliar. Sin embargo, en Perú no se cuentan con reportes sobre la seguridad y eficacia de este procedimiento. Objetivo: Evaluar la seguridad y eficacia del uso de las SEMS en el manejo paliativo de las estenosis malignas de la vía biliar. Materiales y métodos: Cohorte retrospectiva. Se incluyeron a todos los pacientes referidos para colocación de SEMS biliar como parte de un tratamiento paliativo entre enero del 2016 y agosto del 2018. Se obtuvieron las tasas de colocación exitosa de las SEMS, de paliación adecuada de la obstrucción y de complicaciones asociadas al procedimiento. Se evaluó la patencia de la prótesis durante el seguimiento. Se determinó la supervivencia luego de la colocación de la prótesis. Resultados: Se incluyeron 32 pacientes con indicación de manejo paliativo debido a una estenosis maligna irresecable de la vía biliar. El cáncer de páncreas (56,25%) seguido del colangiocarcinoma (31,25%) fueron las etiologías más frecuentes. Se alcanzó una tasa de colocación exitosa en primera intención de 96,97%. La paliación adecuada de la obstrucción biliar se alcanzó en el 100% de los pacientes (p<0,05). Dos SEMStc migraron durante el seguimiento (6,25%) siendo manejados con la colocación de una nueva SEMSnc. Conclusiones: La colocación de SEMS constituye una estrategia segura, con alta tasa de éxito terapéutico en el manejo paliativo de los pacientes con obstrucción maligna de la vía biliar.

OBJECTIVE: To determine the efficacy and safety of double guidewire technique in patients with difficult biliary cannulation during ERCP. MATERIALS AND METHODS: We conducted a retrospective cohort study of all ERCPs performed between January 2015 and July 2016. DGT was performed in patients for whom biliary cannulation was difficult and guidewire insertion into the pancreatic duct (PD) was inadvertently achieved while attempting the standard WGC technique. RESULTS: 24 patients were enrolled with ERCP and DGT; 17 were female (70.8%) and 7 male (29.2%). The average age was 65.21±16.49 years. The most frequent indication was choledocholithiasis (62.5%), then cholangiocarcinoma (12.5%). Post ERCP diagnosis was choledocholithiasis (45.8%), and papillary fibrosis (29.2%). The success of DGT was 87.5%. Three cases of failure cannulation with the DGT were reported, two patients had pancreatitis post ERCP (8.3%), there were no cases of perforations. CONCLUSIONS: TDG, is an effective alternative to difficult biliary cannulation during ERCP with conventional methods; with a high success rate and low rate of post ERCP pancreatitis, similarly to reported in other countries.

Objective: The aim of this study was to report the initial experience of the combined use of biliary sphincterotomy plus balloon dilatation of the papilla for management of large stones. Materials and methods: Design: Retrospective, descriptive. This study included 18 patients in whom a hydrostatic dilatation of the papilla with large balloons was performed between June 2012 and April 2014. Patients had multiple large stones, tapered distal common bile duct, previous sphincterotomy, or peri/ intradiverticular papilla. CRE™ dilatation balloons with diameters ranging from 12 to 20 mm were used. Data were recorded as successful procedure, use of lithotripsy and complications during the procedure. Results: The average age was 66.1 years. There was a predominance of the female gender (66.7%). The average size of the bile duct stones was 16.7 mm. The main indications were: giant choledocholithiasis (12 patients, 66.7%) and tapered distal common bile duct (6 patients, 33.3%). The dilatation balloons diameter used were: 15 mm (8 patients, 44.4%), 18 mm (5 patients, 27.8%), 12 mm (3 patients, 16.7%) and 20 mm (2 patients, 11.1%). Complete stone clearance was achieved in 15 patients (83.3%). Lithotripsy was performed in 4 patients (22.2%). There were 3 patients in whom the removal with balloon was unsuccessful, performed surgical management. It was reported 1 case of mild acute pancreatitis (5.5%). Conclusions: The results show that endoscopic papillary large balloon dilation after sphincterotomy is a safe and effective technique for treatment of difficult bile duct stones

INTRODUCTION: Visceral hypersensitivity has been proposed as a biological marker of Irritable bowel syndrome (IBS). OBJECTIVE: To evaluate the pain perception during sigmoidoscopy using a visual analog scale of pain in patients with or without IBS, and to assess the pain perception as diagnostic criteria for IBS. We further assessed the sensitivity, specificity and diagnostic efficiency of pain scores to diagnose IBS. METHODS: A prospective case-control study in patients who underwent sigmoidoscopy for the evaluation of gastrointestinal symptoms. All patients completed Rome III criteria questionnaires and divided into two groups: IBS and non-IBS. All participants reported pain scores on visual analog scales after of study. Differences were evaluated. We calculated a receiver-operator characteristic curve (ROC), sensitivity, specificity and diagnostic efficiency. RESULTS: We analyzed 20 patients with IBS and 20 controls. The pain scores were higher in IBS patients compared with non-IBS patients (median, 52.5 vs. 27.5, p = 0.006). The area under the curve was 0.84, at pain score level of ≥ 40 mm with a sensitivity, specificity and diagnostic efficiency of 85%, 75% and 80%, respectively. CONCLUSIONS: The degree of pain perception was higher in IBS patients than in non-IBS patients during sigmoidoscopy. A score of pain perception in ≥ 40 mm may predict the diagnosis of IBS with good sensitivity (85%) and specificity (75%).

INTRODUCCIÓN: ante la ausencia de medidas objetivas para realizar el diagnóstico de Síndrome de Intestino Irritable (SII) se plantea el uso de la hipersensibilidad visceral como marcador biológico de la enfermedad. OBJETIVO: evaluar la percepción de dolor durante la sigmoidoscopia flexible mediante el uso de una escala analógica visual del dolor en pacientes con SII, además de valorar la percepción del dolor como criterio diagnóstico de ayuda al SII mediante la sensibilidad, especificidad y eficiencia diagnóstica de un valor de corte. METODOLOGÍA: se realizó un estudio prospectivo, tipo casos y controles, en pacientes con indicación para estudio sigmoidoscópico con y sin SII, para valorar la percepción del dolor después del examen mediante el empleo de una escala analógica visual. Se evaluaron las diferencias y se confeccionó una curva ROC, además de establecer la sensibilidad, especificidad y eficiencia diagnóstica. RESULTADOS: Se analizaron 20 pacientes con SII y 20 controles. El score de percepción del dolor fue mayor en los pacientes SII comparados con los pacientes no SII (mediana, 52.5 vs 27.5, p=0.006). El área bajo la curva fue de 0.84, determinándose un punto de corte en ≥ 40mm con una sensibilidad, especificidad y eficiencia diagnóstica de 85%, 75% y 80% respectivamente. CONCLUSIONES: Los pacientes con SII experimentan mayor percepción del dolor durante la sigmoidoscopia. Un valor de percepción del dolor en ≥ 40mm puede predecir el diagnóstico del SII con una buena sensibilidad (85%) y especificidad (75%).

We report the case of a 35-year-old male patient, with a history of six months of pallor and dyspnea associated with severe iron deficiency anemia and positive fecal occult blood tests. Endoscopy of the lower and upper gastrointestinal tract, and a small bowel follow-through were performed, but did not reveal the origin of the bledding. Later, a capsule endoscopy study were performed and detected an elevated area - not well defined - with active bleeding in the jejunal portion of the small bowel, for that reason we decided to complement the study with a double balloon enteroscopy, that allowed us to see more clearly the jejunal lesion: an elevated and ulcerated lesion; the area was marked with India ink to guide the surgeon. In the surgical intervention a resection of the involved jejunal segment was performed; the study of pathological anatomy established the diagnosis of jejunal angiodysplasia. We present this case of obscure gastrointestinal bleeding to emphasize the diagnostic utility of capsule endoscopy and double balloon enteroscopy.
