The Cystic Duct: Normal Anatomy and Disease Processes
Radiographics, 2020Co-Authors: Mary Ann Turner, Ann S FulcherAbstract:The Cystic Duct can be depicted with a variety of imaging modalities but is optimally visualized with direct cholangiography or magnetic resonance cholangiopancreatography. Nevertheless, unrecognized anatomic variants of the Cystic Duct may cause confusion on imaging studies and complicate subsequent surgical, endoscopic, and percutaneous procedures. Primary entities involving the Cystic Duct include calculous disease, Mirizzi syndrome, Cystic Duct–duodenal fistula, biliary obstruction, neoplasia, and primary sclerosing cholangitis. The Cystic Duct may also be secondarily involved by adjacent malignant or inflammatory processes. Postoperative alterations are seen after liver transplantation or cholecystectomy when a portion of the Cystic Duct is left behind as a remnant. Recognized postoperative complications include retained Cystic Duct stones, Cystic Duct leakage, and malposition of T tubes in the remnant. Pitfalls encountered in Cystic Duct imaging include pseudocalculous defects from overlap of the cy...

the Cystic Duct normal anatomy and disease processes
Radiographics, 2001Co-Authors: Mary Ann Turner, Ann S FulcherAbstract:The Cystic Duct can be depicted with a variety of imaging modalities but is optimally visualized with direct cholangiography or magnetic resonance cholangiopancreatography.

Recognized postoperative complications include retained Cystic Duct stones, Cystic Duct leakage, and malposition of T tubes in the remnant. Pitfalls encountered in Cystic Duct imaging include pseudocalculous defects from overlap of the Cystic Duct and common bile Duct, underfilling of the Cystic Duct during direct cholangiography, and admixture defects at the Cystic Duct orifice. Pseudomass or pseudotumor defects may result from an impacted Cystic Duct stone or from a tortuous, redundant Cystic Duct. Familiarity with the imaging appearance of the normal Cystic Duct, its anatomic variants, and related disease processes facilitates accurate diagnosis and helps avoid misinterpretation.

clinical and pathological features of primary carcinoma of the Cystic Duct
Journal of Hepato-biliary-pancreatic Surgery, 2009Co-Authors: Takenari Nakata, Akira Kobayashi, Shiro Miwa, Junpei Soeda, Takeshi Uehara, Shinichi MiyagawaAbstract:Background According to Farrar’s criteria, a tumor restricted to the Cystic Duct is defined as Cystic Duct carcinoma, but this definition excludes advanced carcinoma originating from the Cystic Duct.

Cystic Duct leaks in laparoscopic cholecystectomy
American Journal of Surgery, 1994Co-Authors: M S Woods, John L Shellito, Gilbert S Santoscoy, Robert C Hagan, Ransom W Kilgore, William L Traverso, Richard A Kozarek, John J BrandaburAbstract:background : Cystic Duct leak (CDL) appears to complicate laparoscopic cholecystectomy (LC) more often than open cholecystectomy (OC). No mention of CDL was found in a literature review that covered 48,822 OCs and their complications. patients and methods : Fifty-four patients who developed biliary tract injuries following LC were reviewed for: the time from LC to presentation, presenting symptoms, method of diagnosis, treatment, outcome, and follow-up. results : Seventeen of 54 biliary tract complications (31%) were CDLs. The CDLs presented at a median of 4 days after LC with pain (76%) and nausea and/or vomiting (35%). Endoscopic retrograde cholangiopancreatography (ERCP) defined the diagnosis and the anatomy of the leak in 11 patients (65%). Biliary endoprosthesis placement was employed in 8 patients, with concomitant sphincterotomy in 5 (63%), and resolved CDL in every case. Seven (88%) of these patients were asymptomatic at a median interval of 10 months after stent retrieval. Six patients (35%) underwent reoperation. Five had laparotomy with ligation of the Cystic Duct stump and 1 underwent laparoscopic examination with reclipping of the Cystic Duct stump. Five (83%) were asymptomatic at a median follow-up of 26 months. CDLs may result from inaccurate clip placement, perforations proximal to the clips, and stump necrosis, as documented at reoperation. conclusions : CDLs occur more frequently in LC than in the OCs reported in the literature. Most leaks require intervention. ERCP with stent placement is the diagnostic and therapeutic procedure of choice and has a high success rate of resolving leaks. To forestall CDLs, it is important to place clips accurately and avoid electrocautery in the vicinity of the Cystic Duct.
