Endoscopic rescue of a fistulizing biliary plastic stent.

55-year-old male with a history of cholecystectomy complicated by perforation of the common bile duct, contained with placement of a plastic biliary stent. He presented several subsequent episodes of recurrent cholangitis secondary to biliary lithiasis and residual benign stenosis of the common bile duct, resolved with the implantation of plastic biliary prostheses. Finally, given the recurrent episodes of cholangitis, it was agreed to perform a hepaticojejunostomy. During the operation, the last implanted stent was not detected, which was identified by CT scan of the abdomen, causing a fistulous tract between the duodenum and the ascending colon. The stent was removed endoscopically, without complications, and the fistulous tract was resolved.

Síndrome del conducto pancreático desconectado. Abordaje endoscópico. / Disconnected pancreatic duct syndrome. Endoscopic approach

El síndrome del conducto pancreático desconectado (SCPD) es debido a la interrupción del conducto pancreático (CP) principal o sus ramas secundarias, complicación presente entre un 30-80% de las pancreatitis agudas necrotizantes. La secreción de enzimas pancreáticas por el tejido pancreático aislado funcionante puede facilitar la recurrencia de colecciones necróticas encapsuladas, por lo que su manejo endoscópico sigue siendo un tema controvertido en la práctica diaria. Exponemos un caso de síndrome de ducto pancreático desconectado resuelto tras colocación de prótesis pancreática. (AU)

Disconnected pancreatic duct syndrome. Endoscopic approach.

Disconnected pancreatic duct syndrome (DPCS) is due to disruption of the main pancreatic duct (PC) or its secondary branches, a complication present in 30-80% of acute necrotizing pancreatitis. The secretion of pancreatic enzymes by isolated functioning pancreatic tissue can facilitate the recurrence of encapsulated necrotic collections, so its endoscopic management remains a controversial issue in daily practice. We present a case of disconnected pancreatic duct syndrome resolved after placement of a pancreatic stent.

Megacolon de etiología infecciosa poco frecuente en nuestro país: enfermedad de Chagas / No disponible

No disponible

Megacolon with infectious etiology that is infrequent in our country: Chagas disease.

We present the case of a 37-year-old male with constipation refractory to medical treatment, in the context of megacolon due to Chagas disease. The entire gastrointestinal tract may be affected but the digestive form is characterized by megaesophagus and megacolon. There is altered peristalsis due to the destruction of the neurons of the enteric nervous system caused by the parasite. Although the mortality rate is low, the disease can have a considerable impact upon quality of life. Chagas disease is poorly recognized and undertreated by healthcare providers in non-endemic regions.

Xanthogranulomatous cholecystitis: differential diagnosis between acute cholecystitis and gallbladder cancer.

We present the images of ultrasound, magnetic resonance and histology of a patient with suggestive findings of xanthogranulomatous cholecystitis. Gallbladder cancer cannot be completely ruled out until the histological study of the surgical sample is performed.

Colon perforation due to fistulization of a pancreatic pseudocyst.

We present a computed tomography image of a patient with acute necrotizing pancreatitis due to alcohol, who developed several pseudocysts, one of which fistulized into the colon.
