Anatomical liver resection of segment 4a en bloc with the caudate lobe
No full textAnatomical segmentectomy is the complete resection of an area supplied by a segmental portal branch. Among segmentectomies, isolated segmentectomy 4 is a technically demanding procedure because there are two transection planes: on the left side along the umbilical fissure and, on the right side, along the middle hepatic vein. Although there are several reports on anatomic segmentectomies, only few regard the anatomic segmentectomy 4a. We report here the case of a 60-year-old man who underwent anatomical segmentectomy 4a en bloc with the caudate lobe to resect a colorectal liver metastasis located in segment 4a and involving the paracaval portion of the caudate lobe. This type of procedure was planned in order to maximize the postoperative functional hepatic reserve, thereby reducing the risk of postoperative liver failure and ultimately allowing the possibility for future repeat hepatectomy in case of recurrence.

Primary Hepatic Angiosarcoma
No full textPrimary hepatic angiosarcoma is a rare entity, representing only 4%
of all the angiosarcomas of different origins1 and less than 1% of all
hepatic malignancies.2
Accurate diagnosis of this tumour is difficult, especially if the
patient has no history of exposure to specific carcinogens including
thorotrast, arsenicals and vinyl chloride monomer.3
Angiosarcoma, a subtype of soft tissue sarcoma, is an aggressive
malignant disease deriving from endothelium, lymphatics or blood
vessels. Some of the more common hepatic sarcomas are angiosarcoma,
embryonal sarcoma, leiomyosarcoma, epithelioid hemangioendothelioma,
fibrosarcoma and malignant fibrous histiocytoma.2
The survival of hepatic angiosarcoma is very poor, which is attributable
to its rapid progress, high recurrence rate and resistant to
traditional chemotherapy and radiotherapy.4 The survival of patients
with liver angiosarcoma is very poor with median survival of 6
months without treatment; after treatment, only 3% of patients were
reported to live longer than 2 year

Unexpected discovery of massive liver echinococcosis. A clinical, morphological, and functional diagnosis
No full textWe report a case of symptomatic massive liver echinococcosis due to Echinococcus granulosus, unexpectedly found in a 34 year old woman living in Apulia, Italy. Based on size (max diameter 18 cm), clinical presentation, geographical area, and natural history of echinococcosis, we estimate that the initial infection should have occurred 9-20 yrs before. Presenting symptoms were those of typical mass effect with RUQ pain, pruritus, malaise, and recent weight loss. Abdominal ultrasound diagnosis of probable echinococcal cyst was subsequentely confirmed by positive serology and further detailed by radiological imaging. The cyst was massively occupying subdiaphragmatic liver segments and extending to the omentum and the stomach. The characteristics of the lesion were compatible with the WHO 2003 classification type CE2l, indicating a large active fertile cyst with daughter cysts. The cyst was successfully treated with medical therapy followed by surgery. The prevalence, diagnostic workup, management, and costs of echinococcosis are discussed in this case presentation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
