1/27. Successful treatment of a pseudoaneurysm of the cystic artery with microcoil embolization.Pseudoaneurysms of visceral arteries are uncommon but well-characterized vascular abnormalities, usually provoked by intraabdominal inflammatory processes such as pancreatitis or cholecystitis, or by surgical trauma. However, pseudoaneurysms of the cystic artery are rare. They complicate cholecystitis or cholecystectomy, and manifest as hemobilia as they rupture into the biliary tree. The advent of transcatheter embolization techniques has begun to allow minimally invasive treatment of these life-threatening complications. Transcatheter embolization can be performed using several types of material, such as synthetic occlusive emulsions, gelatin sponges or other particles, or metallic microcoils. Microcoils are small metallic helical particles, made of stainless-steel, platinum, or tungsten. Super-selective catheterization of an artery and release of microcoils causes the vessel to thrombose and allows control of bleeding.- - - - - - - - - - ranking = 1keywords = cholecystitis (Clic here for more details about this article) |
2/27. Acute cholecystitis secondary to hemobilia.Invasive diagnostic and therapeutic techniques such as percutaneous transhepatic cholangiography, endoscopic retrograde cholangiopancreatography (ERCP), transjugular intrahepatic portosystemic shunting, and laparoscopic cholecystectomy have led to a rise in hemobilia. Most complications from hemobilia are attributable to acute blood loss; other complications are secondary to thrombus formation in the biliary tree. We present a case report of acute cholecystitis secondary to hemobilia after percutaneous liver biopsy. The role of ERCP in the diagnosis and treatment of this exceedingly rare event is discussed.- - - - - - - - - - ranking = 2.5keywords = cholecystitis (Clic here for more details about this article) |
3/27. Sequential sonographic changes of the gallbladder in hemobilia: case report of a patient with intrahepatic duct stones.The sonographic features of hemobilia in the gallbladder have been reported with variation, including an echogenic mass, hypoechoic mass, and scattered intraluminal echoes. The sequential sonographic changes of hemobilia in the gallbladder were observed in a 59-year-old male patient with bilateral intrahepatic duct stones. The sonograms of hemobilia in the distended gallbladder initially showed a hyperechoic, homogeneous, movable mass-like lesion, 36 hours before the onset of upper gastrointestinal (UGI) bleeding. A hypoechoic mass-like lesion with a hyperechoic ring was found 5 days after the onset of UGI bleeding. A faint hypoechoic mass-like lesion was found 7 days after the onset of UGI bleeding (the day of no further bleeding). Scattered echoic densities were found 9 days after the onset of UGI bleeding, then disappearance of the lesion was noted 12 days after the onset of UGI bleeding. The sonographic patterns of hemobilia in the gallbladder vary depending on the timing of lysis of the blood clot. It should be differentiated from gallbladder cancer, a stone, a polyp, sludge, acute gangrenous cholecystitis, and gallbladder empyema.- - - - - - - - - - ranking = 0.5keywords = cholecystitis (Clic here for more details about this article) |
4/27. cholecystitis caused by hemocholecyst from underlying malignancy.Massive hemobilia is a well recognized clinical entity, particularly when it presents with jaundice, GI bleeding, and biliary pain. However, occult hemobilia is more difficult to diagnose and has seldom been reported because of its clinically silent nature. In fact, this is usually overlooked until complications arise. Hemocholecyst or clot within the gallbladder may rarely occur in this setting, leading to cystic duct obstruction and cholecystitis. Most previous reports describe cholecystitis resulting from hemocholecyst after iatrogenic trauma. We describe two cases in which hemocholecyst occurred from underlying malignancies, both resulting in cholecystitis (acute or chronic).- - - - - - - - - - ranking = 1.5keywords = cholecystitis (Clic here for more details about this article) |
5/27. Acute cholecystitis secondary to hemobilia after percutaneous liver biopsy.A case of obstructive acute cholecystitis following percutaneous liver biopsy is presented. The patient complained of intense and continuous pain in the right upper quadrant of the abdomen 2 days after the liver biopsy. On abdominal examination, Murphy's sign was present. Hemogram revealed a fall in the hematocrit level from 44 to 38 because of hemobilia. ultrasonography showed a dilated gallbladder with moderate thickness of the wall and a blood clot of 20 x 9 mm inside. The patient was subjected to laparoscopic cholecystectomy. The acute inflammation of the gallbladder was secondary to obstruction of the cystic duct by the blood clot. The postoperative period was uneventful.- - - - - - - - - - ranking = 2.5keywords = cholecystitis (Clic here for more details about this article) |
6/27. Hemorrhagic cholecystitis as a likely cause of nontraumatic hemobilia in metachromatic leukodystrophy: report of a case.A 17-years-old man with the juvenile form of MLD developed massive hemobilia. CT and US scans showed blood and clots filling the gallbladder and the biliary ways, with no bleeding source seen at selective angiography. Explorative laparotomy evidenced bleeding from a papillomatous gallbladder mucosa, resolved with cholecystectomy. Histologic examination with specific colorations diagnosed hemorrhagic cholecystitis from metachromatic leukodystrophy of the gallbladder. This is, to our knowing, the third case reported in literature, and thus hemorrhagic cholecystitis may be considered a life-threatening complication of MLD to be prevented with cholecystectomy as soon as signs of gallbladder pathology (papillomatosis/polyposis, jaundice, abdominal pain) are suspected.- - - - - - - - - - ranking = 3keywords = cholecystitis (Clic here for more details about this article) |
7/27. Pseudoaneurysm of the cystic artery with hemobilia treated by arterial embolization and elective cholecystectomy.Pseudoaneurysm of the cystic artery is a rare cause of hemobilia, with only 11 cases having been reported in the English literature. We report this unusual condition in a 62-year-old Japanese man whose chief complaint was repeated upper abdominal pain. A liver function test showed obstructive jaundice, and endoscopy revealed a small amount of blood coming from the papilla of Vater. We diagnosed him as having hemobilia, and immediate angiography was performed. The results demonstrated a pseudoaneurysm arising in the cystic artery. Selective embolization of the cystic artery then followed. Ten days later the patient underwent elective cholecystectomy and had a good postoperative course. Microscopically, the resected specimen revealed caliculous cholecystitis and an organized pseudoaneurysm perforating the lumen of the gallbladder. We supposed that this pseudoaneurysm was associated with the inflammatory reaction seen with the acute cholecystitis. This case emphasizes the need for a high level of awareness of hemobilia whenever bleeding is associated with signs of biliary disorders. Immediate angiography and embolization of the pseudoaneurysm followed by radical surgery may be the preferred strategy. We believe this is the first reported case of successful "two-step" treatment of such a pseudoaneurysm.- - - - - - - - - - ranking = 1keywords = cholecystitis (Clic here for more details about this article) |
8/27. Laparoscopic management of traumatic hemorrhagic cholecystitis.BACKGROUND AND OBJECTIVES: Blunt trauma to the gallbladder is a rare entity, particularly when no other organ is injured. In isolated blunt traumatic injury to the gallbladder, treatment options vary depending on the specific injury. The types of blunt trauma injuries to the gallbladder and their appropriate management are discussed. In addition, a case successfully managed with minimally invasive techniques is presented. methods: A passenger admitted after a high-speed front-end motor vehicle crash was safely managed with laparoscopic surgery for a rare case of isolated gallbladder trauma. The preoperative and operative management are discussed as well as the application of minimally invasive surgery for this rare process. RESULTS: Laparoscopic cholecystectomy was performed successfully. The patient did well postoperatively with no complications. No other injuries were identified at the time of laparoscopy. CONCLUSION: Minimally invasive techniques may be safely applied to blunt trauma of the gallbladder in certain circumstances.- - - - - - - - - - ranking = 2keywords = cholecystitis (Clic here for more details about this article) |
9/27. hemobilia secondary to chronic cholecystitis.The term hemobilia is used to describe the presence of blood in the biliary tract. We report a case of symptomatic hemobilia associated with chronic cholecystitis in a 57-year-old man with jaundice, gastrointestinal hemorrhage, and epigastric pain. We review the etiology of this condition and highlight the role of abdominal ultrasonography in its diagnosis. In our case, abdominal ultrasonography revealed the presence of clots inside the gallbladder. The clinical condition was resolved by means of a cholecystectomy. The patient had an uneventful recovery.- - - - - - - - - - ranking = 2.5keywords = cholecystitis (Clic here for more details about this article) |
10/27. Acute cholecystitis with a hemocholecyst as an unusual presentation of gallbladder cancer: report of a case.Several atypical presentations of gallbladder carcinoma have been reported, but one of the rarest is intraluminal hemorrhage. We report a case of carcinoma of the gallbladder disclosed by an emergency cholecystectomy, performed for acute cholecystitis caused by a hemocholecyst. The diagnostic approaches and characteristics of a hemocholecyst associated with carcinoma of the gallbladder are discussed.- - - - - - - - - - ranking = 2.5keywords = cholecystitis (Clic here for more details about this article) |
