Nov 12, 2024 · The liver typically extends from the fifth intercostal space to the right costal margin in the midclavicular line. By ultrasound, a normal liver span is usually <16 cm in the midclavicular line; however, liver size varies with sex and body size .

Nov 12, 2024 · This topic provides an overview of normal liver size, causes of hepatomegaly, and an approach to evaluating hepatomegaly in adults. The diagnosis and management of hepatic injury in adults is discussed separately. (See "Management of hepatic trauma in adults".)

Wider resection margin (>1 vs<1 cm) was significantly associated with improved OS at 3 years (pooled RR = 0.86, 95% CI: 0.79-0.95), 5 years (pooled RR = 0.91, 95% CI: 0.85-0.97), and 10 years (pooled RR = 0.94, 95% CI: 0.88-1.00).

Feb 8, 2022 · The liver margin, which can usually be palpated 2 to 3 cm below the right rib margin, rises and falls with the diaphragm during respiration. The dome of the liver rises as high as the level of T4 (nipple) with expiration.

Hepatic hemangiomas are often solitary but multiple lesions may be present. Most patients with hepatic hemangiomas are asymptomatic and have an excellent prognosis, while symptoms are more likely to occur in patients with large lesions. The etiology of hepatic hemangiomas is incompletely understood.

Perioperative outcomes for hepatic resection have improved due to better surgical techniques that take advantage of the segmental anatomy of the liver, improved techniques for control of bleeding, and improved intensive care.

Extended right hemicolectomy refers to extension of the distal resection margin to include the distal transverse colon up to the splenic flexure. The techniques used to perform right and extended right colectomy are reviewed here.

Jul 30, 2024 · Some cystic lesions of the liver may have unique complications such as malignant transformation in the case of a mucinous cystic neoplasm (cystadenoma) or a ciliated hepatic foregut cyst, or anaphylactic shock due to a hydatid cyst.

The approach in this topic applies to liver lesions found incidentally in adult patients without signs or symptoms (eg, right upper quadrant pain) attributable to the lesion and without risk factors for hepatic malignancy.

Nov 12, 2024 · Hepatic granulomas may be found incidentally on an otherwise normal liver biopsy or may be caused by systemic diseases (eg, infection, autoimmune disease). Although the granulomas alone rarely affect liver function, it is important to identify an underlying systemic disease since it may have prognostic and therapeutic implications.
