Acute pancreatitis due to osteosarcoma metastasis.

We present the case of a young patient with acute pancreatitis (AP) secondary to osteosarcoma metastasis. It is necessary to assess tumor etiology in the study of any acute pancreatitis without clear cause. Pancreatic metastases are rare and difficult to diagnose and differentiate from other primary tumors such as neuroendocrine tumors (NET). It is essential to have a high degree of clinical suspicion and the use of radiological and endoscopic ultrasound imaging techniques.

Endoscopic treatment of disconnected pancreatic duct syndrome secondary to acute necrotizing pancreatitis in a patient with pancreas divisum.

A 50-year old male with acute necrotizing pancreatitis had an unfavorable evolution in the third week of disease, with development of large volume ascites and walled-off necrosis affecting the head and body of pancreas, suspected to be infected, with viable parenchyma in the tail of pancreas. Endoscopic ultrasound guided drainage of the collection was performed through placement of a lumen apposing metal stent. Selective cannulation of main pancreatic duct was only possible though the minor papilla and after contrast media injection a type 1 pancreas divisum and partial disruption of dorsal pancreatic duct were diagnosed.

The volume of ERCP per endoscopist is associated with a higher technical success and a lower post-ERCP pancreatitis rate. A prospective analysis.

INTRODUCTION: conflicting results have been reported regarding the influence of the annual volume of endoscopic retrograde cholangiopancreatography (ERCP) on outcome. OBJECTIVE: to evaluate the influence of case volume on ERCP outcomes. PATIENTS AND METHODS: an analysis of a prospective database was performed, comparing the outcomes of ERCP in three consecutive periods defined by the number of endoscopists performing ERCP: five endoscopists in period I (P1), four in period II (P2) and three in period III (P3). Only patients with biliary ERCP in accessible and naïve papilla were included. Primary variables were cannulation rates and adverse effects (AE). The American Society of Gastrointestinal Endoscopy (ASGE) complexity grades III and IV were considered as highly complex procedures. RESULTS: a total of 2,561 patients were included: 727 (P1), 972 (P2) and 862 (P3). There were no differences in age and sex between groups (p > 0.05). The cannulation rate was significantly higher in P2 and P3: 92.4 % vs 93.3 % vs 93 % (p = 0.037). The AE rate was 13.8 %, 12.6 % and 10.3 % (p > 0.05), respectively. The rate of post-ERCP pancreatitis was significantly lower in P3: 8.5 %, 7.3 % and 5 % (p = 0.01). The rate of complex procedures was 12 %, 14.8 % and 27 % (p < 0.0001), respectively. Two endoscopists participated in all periods and only one had significantly improved outcomes. Cannulation and post-ERCP pancreatitis rates remained significantly better in P3 after adjusting for sex, complexity and endoscopist. CONCLUSION: a higher annual volume of ERCP per endoscopist was associated with a higher rate of cannulation and a lower rate of post-ERCP pancreatitis, despite the greater complexity of the procedures. These beneficial effects seem to differ between endoscopists.

Gastrointestinal infection by Mycobacterium avium with an unusual endoscopic presentation.

A 38-year-old male with medical history of HIV group C3 with voluntary abandonment of antiretroviral therapy, was hospitalized due to general deterioration, abdominal pain, diarrhea and rectal bleeding without signs of acute abdomen. The patient presented anemia, renal and hepatic dysfunction, and metabolic acidosis. Abdominal CT and CT angiography were performed without observing signs of perforation or active bleeding. In the same year, he was also diagnosed of intestinal Cryptosporidiosis, cutaneous Kaposi's sarcoma and disseminated infection by Mycobacterium avium (MA) with lung, liver and bone marrow involvement. Panendoscopy was performed, showing violaceous lesions on the soft palate. In the stomach and duodenum, he presented multiple, large, well-defined and occasionally confluent red-violet lesions Colonoscopy did not show macroscopic alterations.

El volumen de CPRE por endoscopista se asocia a mayor tasa de éxito y menor tasa de pancreatitis post-CPRE. Análisis de un registro prospectivo / The volume of ERCP per endoscopist is associated with a higher technical success and a lower post-ERCP pancreatitis rate. A prospective analysis

Introducción: la influencia del volumen anual de colangiopancreatografía retrógrada endoscópica (CPRE) en sus resultados ha sido analizada con resultados contradictorios.Objetivo: evaluar la influencia del volumen de CPRE en sus resultados. Material y métodos: análisis sobre base de datos prospectiva comparando los resultados de la CPRE en tres periodos definidos por el número de endoscopistas que la realizan: periodo I, con cinco endoscopistas; periodo II, con cuatro; y periodo III, con tres. Incluimos CPRE biliar en papila acce sible y virgen. Las variables principales fueron las tasas de canulación y los efectos adversos. Los grados de complejidad III y IV, según la clasificación de la Sociedad Americana de Endoscopia Digestiva (ASGE, por sus siglas en inglés), se consideraron procedimientos de alta complejidad. Resultados: fueron incluidos 2.561 pacientes: 727 (periodo I), 972 (periodo II) y 862 (periodo III). No hubo diferencias en edad y sexo entre grupos (p > 0,05). La tasa de canulación fue significativamente mayor en los periodos II y III: 92,4 % vs. 93,3 % vs. 93 % (p = 0,037). La tasa de efectos adver sos (EA) fue de 13,8 %, 12,6 % y 10,3 % (p > 0,05). La tasa de pancreatitis post-CPRE fue significativamente menor en el periodo III: 8,5 %, 7,3 % y 5 % (p = 0,01). El porcentaje de procedimientos de alta complejidad fue de 12 %, 14,8 % y 27 % (p < 0,0001), respectivamente. La regresión logística mostró tasas de canulación y pancreatitis post-CPRE significativamente mejores en el periodo III tras ajustar por sexo, complejidad y endoscopista. Conclusión: un mayor volumen anual de CPRE por endoscopista se asoció con mayor tasa de canulación y menor tasa de pancreatitis post-CPRE, a pesar de la mayor complejidad de los procedimientos. Estos efectos beneficiosos parecen diferir entre endoscopistas(AU)

Primary adenocarcinoma of the fourth portion of the duodenum, an unsuspected diagnosis.

Small bowel adenocarcinoma is a rare tumor accounting for only 0.3-0.4% of all gastrointestinal tumors, with duodenal adenocarcinoma being the most common subtype. In most patients, it presents with nonspecific signs and symptoms, often leading to a delay in diagnosis. Therefore, it is essential to establish an adequate initial clinical suspicion to carry out an adequate diagnostic approach, being necessary to perform both radiological and endoscopic diagnostic techniques.

Rescate con rituximab en paciente con liquen plano esofágico refractario / Rituximab as rescue therapy in refractory esophageal lichen planus

El liquen plano esofágico (LPE) es una entidad poco frecuente cuya prevalencia se desconoce, que puede en ocasiones estar subestimada por los hallazgos sutiles e inespecíficos en las exploraciones realizadas. Las lesiones orales rara vez se extienden para afectar a la mucosa esofágica pero, cuando lo hacen, provocan disfagia y odinofagia. Esta infrecuente afectación del liquen plano conlleva un retraso en el diagnóstico y un tratamiento inadecuado. Se presenta el segundo caso (en nuestro conocimiento) de una paciente de 59 años con LPE, con buena respuesta al tratamiento con rituximab, un anticuerpo monoclonal quimérico dirigido específicamente contra la proteína CD20 presente en los linfocitos B (AU)

Esophageal lichen planus (ELP) is a rare condition with unknown prevalence that can sometimes be underestimated due to the subtle and nonspecific findings of diagnostic workup. Oral lesions rarely extend to the esophageal mucosa, but when they do, the most frequent symptoms are dysphagia and odynophagia. There is often a significant delay in diagnosis and inadequate treatment. We report the case of a 59-year-old woman diagnosed with ELP, successfully treated with rituximab, a chimeric monoclonal antibody that depletes CD20+B cells. To our knowledge, this is only the second report of this treatment in ELP (AU)

Carbon dioxide vs. air insufflation in ileo-colonoscopy and in gastroscopy plus ileo-colonoscopy: a comparative study.

INTRODUCTION: insufflation with carbon dioxide (CO2) during endoscopies compared to air is associated with a decrease in abdominal discomfort after the examination, because CO2 is readily absorbed through the small intestine and eliminated by the lungs. AIM: the objective of this randomized clinical trial was to assess the effect of CO2 insufflation on pain and abdominal distension after an ileo-colonoscopy (I) and after an ileo-colonoscopy plus gastroscopy (I+G). MATERIAL AND METHODS: we included a total of 309 patients in the study and all endoscopies were performed under sedation with propofol. Two hundred fourteen patients underwent an I (132 with CO2 / 82 with air) and 95 underwent an I+G (53 with CO2 / 42 with air). Abdominal pain was studied at 10, 30 and 120 minutes of exploration and abdominal perimeter difference before and after the procedure. RESULTS: both in group I and in group I+G, the use of CO2 translated into an average of abdominal pain significantly lower (p < 0.05). Similarly, a smaller increase in waist circumference was found among group I and group I+G, in patients where CO2 was used (p < 0.05). CONCLUSION: the insufflation of CO2 instead of air during the performance of endoscopy significantly reduces the discomfort and abdominal pain after an ileo-colonoscopy and after a gastroscopy + ileo-colonoscopy.

Insuflación de CO2 vs. aire en íleo-colonoscopia y en gastroscopia más íleo-colonoscopia: estudio comparativo / Carbon dioxide vs. air insufflation in ileo-colonoscopy and in gastroscopy plus ileo-colonoscopy: a comparative study

Introducción: la insuflación con dióxido de carbono (CO2) durante las endoscopias digestivas comparado con el aire, se asocia a una disminución de las molestias abdominales después de la exploración, ya que el CO2 es fácilmente absorbido por el intestino delgado y eliminado por los pulmones. Objetivo: el objetivo de este ensayo clínico aleatorizado fue valorar el efecto de la insuflación de CO2 sobre el dolor y la distensión abdominal después de una ileo-colonoscopia (I) y después de una íleo-colonoscopia + gastroscopia (I+G). Material y métodos: se incluyeron un total de 309 pacientes en el estudio y todas las endoscopias fueron realizadas bajo sedación con propofol. A 214 pacientes se les realizó una I (132 con CO2 / 82 con aire) y a 95 se les realizó una I+G (53 con CO2 / 42 con aire). Se estudió el dolor abdominal a los 10, 30 y 120 min de la exploración y la diferencia de perímetro abdominal antes y después del procedimiento. Resultados: tanto en el grupo I como en el grupo I+G, se objetivó una media de dolor abdominal en los pacientes en los que se utilizó CO2 significativamente menor que en los que se utilizó aire (p < 0,05). Y de igual modo se objetivó un menor incremento en el perímetro abdominal para el grupo I y para el I+G en los pacientes en que se utilizó CO2 frente a los que se utilizó aire (p < 0,05). Conclusión: la insuflación de CO2 en vez de aire durante la realización de la exploración endoscópica, reduce significativamente el disconfort y el dolor abdominal después de una íleo-colonoscopia y después de una íleo-colonoscopia + gastroscopia(AU)
