A typical bile duct branching patterns represent one of the major causes of bile duct injury (BDI) during laparoscopic cholecystectomy (LC). The most common classified variations of bile duct branching, involve the right posterior sectoral duct (RPSD) and its joining with the right anterior or left hepatic duct. Variant bile duct anatomy can rarely be extremely complex and unclassified. This report describes an extremely rare case of an isolated injury to an aberrant right hepatic duct formed by the joining of ducts from segments V, VII, and VIII draining into the cystic duct (cysticohepatic duct) during LC, associated with an inferior RPSD opening to left hepatic duct. Detailed evaluation of both endoscopic and magnetic cholangiograms established the diagnosis. Bile duct injury was subsequently managed surgically by a demanding Roux-en-Y hepaticojejunostomy. This extremely rare case aims to serve as a useful reminder of the consistent inconsistency of biliary anatomy, alerting surgeons to beware of variant bile duct branching patterns during open or LC that constitute a dreadful pitfall for severe and life-threatening bile duct injuries.
The perivascular spaces are normally microscopic. Even in normal brain some Robin-Virchow spaces are usually seen in the area of substantia innominata at the level of anterior commissure. Many pathologic states result in abnormal dilatation with an increased number of spaces visible on MRI imaging. Dilatation is most commonly associated with anterior abnormalities that arise due to aging, diabetes, hypercholesterolemia, smoking, hypertension and other vascular risk factors. The precise etiology of dilatation is currently unknown.
Introduction and hypothesis
The objective was to present endoscopic images of a meshoma and describe the complete excision of a complicated mesh after sacrocolpopexy (SCP) using a combined vaginal-endoscopic technique.
Methods
We present a video documentation of an innovative technique. A 58-year-old woman was referred with painless, foul-smelling vaginal discharge and recurrent vaginal mesh erosions. She had undergone a laparoscopic SCP 12 years ago and her symptoms had begun 5 years ago. A pre-operative MRI scan revealed a cuff meshoma and an inflammatory sinus around the mesh extending from the cuff to the sacral promontory. Under general anesthesia, a 30° hysteroscope was inserted transvaginally into the sinus, where the retained mesh was seen in the form of a shrunken meshoma, and then the mesh arms were recognized extending cephalad into a sinus tract. Under direct endoscopic visualization, the mesh was carefully mobilized at its highest point with the use of laparoscopic grasping forceps. Then, the mesh was dissected with hysteroscopic scissors in close proximity to the bone. No peri-operative complications were recognized.
Results
A combined vaginal-endoscopic approach was successfully used to remove an eroded mesh and cuff meshoma after SCP.
Conclusion
This procedure offers a minimally invasive, low-morbidity, and rapid-recovery approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
