Substantial knowledge of the arterial supply and its anatomical variations of the gall bladder and liver are important in all the hepatobiliary surgical procedures. The arterial supply of gallbladder called cystic artery (CA) is a vital structure required to get ligated or clipped in the path of laparoscopic cholecystectomy. The possible concerns like intra-operative bleeding or adjoining accidental injuries will almost always be focused on the research consisting of dissection and clipping with cystic artery. Pseudoaneurysm of the cystic artery has additionally been belonging to the presence of acute cholecystitis or pancreatitis. An original supply of CA is usually assessed depending on the existence of hepatic artery variants. Laparoscopic cholecystectomy is really a recent and arduous noninvasive procedure and might even result in substantial unintended effects possibly iatrogenic or in the form of post-procedural complications. The perfect knowledge of anatomy in addition to feasible variation of cystic artery is mandatory. An efficient operative strategy and consciousness are probably the key components with all the results and marginal likelihood of complications, which often can be ultimately attainable. Within this chapter, we have attempted to explore some variations of cystic artery, complications and management.

Peri-hilar cholangiocarcinoma (PHC) or hilar cholangiocarcinoma (HCCA) characterizes a critical effort to assess significantly sick patients. The existing scenery and proof to the diagnosis and treatments for hilar cholangiocarcinoma are improving day by day. Patients with HCCA encounter numerous obstacles in acquiring efficient therapies. The condition is uncommon, and the majority patients don’t have any distinct risk factors, doing selection process inadequate. The initial signs and symptoms in many cases are non-specific, and in many patients the tumors are not resectable because of involvement of the perihilar structures. MRI with MRCP offers further information about the extent of biliary involvement. Furthermore, endoscopic stenting and percutaneous drain could be useful for intricate hilar strictures. Surgical resections with negative margins are related to good likelihood of survival for patients representing with HCCA. Regardless of the accessibility of curative treatment strategies such as operative resection and liver transplantation, most sufferers with HCCA shows with repeated, metastases or locally advanced disease with a poor prognosis. Within this chapter, we have tried to elaborate the modalities of treatment from intervention to surgical approach for HCCA.
