Abstract
Although many of the advances in hepatic surgery have been linked to improvements in technology, there is no denying the impact of thorough knowledge of the internal anatomy of the liver on improved outcomes. This is largely due to the work of the French surgeon and anatomist, Claude Couinaud (1922–2008), (The Liver: Anatomic and Surgical Studies), in 1957, regarding segmental anatomy of the liver. Couinaud was able to closely examine the intrahepatic anatomy and demonstrated that hepatic functional anatomy is based on vascular and biliary relationships rather than external surface anatomy, improving the safety and feasibility of hepatic surgery today (Mark Bloomston et al., 2010).
Segmental resection is a safe technique that allows complete resection of liver tumors with preservation of normal liver parenchyma (Paul et al., 2007).
Hepatectomy is now associated with much lower morbidity and mortality and its use has been expanded to include many nonmalignant liver lesions (Paul et al., 2007).
In conclusion, the scope of this study was to evaluate the anatomical resection for liver hydatid cyst once the diagnosis had been confirmed. It is important to emphasize that in endemic areas, the diagnosis of liver hydatid cysts is made based on epidemiological and clinical considerations, and ultrasound examination. This is supported by expert consensus on the diagnosis and treatment of the hydatid cyst.
We show that HR is a safe and effective procedure for the management of hepatic hydatid disease. Operative mortality and morbidity rate was low with few cavity-related complications with no recurrence was noted in our study.
Also we evaluate the role of anatomical resection of hepatic hydatid cyst in reducing blood loss and morbidity also complete resection without leakage of cyst content and leaving adequate functional liver.
