Gasless laparoscopic resection of hepatocellular carcinoma (HCC) in cirrhosis.

Liver resection by open surgery remains the method of choice for treatment of hepatocellular carcinoma (HCC) in cirrhotic patients with compensated liver function. Laparoscopy for surgical treatment of hepatic diseases is at an early stage. Laparoscopy has been often proposed for diagnosis, staging of hepatic malignancy, treatment of hepatic cyst or benign tumors, but very few laparoscopic treatments of hepatic malignancies have been reported at present and always using conventional CO2 laparoscopy. We describe herein the operative treatment of a single subglissonian HCC of segment III in a child, HCV (hepatitis C virus)-related cirrhosis. A nonanatomical wedge resection was performed by gasless laparoscopic technique using a mechanical retractor obviating the creation of the pneumoperitoneum and of the sealed environment. The technique, in selected cases, is a simple, safe, and effective surgical method. The gasless technique guarantees a clear vision, it makes possible the continuous suction of smoke and fluids, it allows the use of conventional instruments for classic maneuvers of the liver surgery (Pringle maneuver), and the easy management of suturing. The present case has proved to be another abdominal procedure that can be carried out with all the advantages of gasless minimally invasive surgery.

The evaluation of fine-needle procedures for the diagnosis of focal liver lesions in cirrhosis.

To evaluate the diagnostic accuracy of fine-needle aspiration, fine-needle biopsy and extranodular fine needle biopsy in identifying focal lesions in cirrhosis, 100 consecutive ultrasound detected nodules were studied. Seventy-three were hepatocellular carcinomas (31 were well-differentiated hepatocellular carcinomas), 23 were benign lesions (one angioma and 22 large regenerative nodules) and two were metastases. The lesions were divided according to maximum diameter as follows: < 20 mm in 36, > 20 < 30 mm in 27, and > 30 mm in 33. In four cases there were multiple nodules of different sizes. Fine needle aspiration, intranodular fine needle biopsy and extranodular fine needle biopsy were obtained in each lesion. The sensitivity, specificity and diagnostic accuracy of each procedure were evaluated separately by three independent pathologists. Seven fine needle aspirations and three intranodular fine needle biopsies were considered inadequate. The highest diagnostic accuracy (96%) was obtained by the combined analysis of fine needle aspiration plus intranodular and extranodular fine needle biopsy, and this superiority was confirmed in each group of lesions. Fine needle aspiration showed a lower accuracy (48%) than intranodular fine needle biopsy (67%). When fine needle aspiration and intranodular fine needle biopsy were evaluated together, an accuracy of 91% was found. Intralesional fine needle biopsy plus extranodular fine needle biopsy analysis gave an accuracy of 78% and, particularly relevant, a specificity of 95%. These results indicate that, in patients with cirrhosis with nodular lesions < 30 mm, fine needle biopsy is superior to fine needle aspiration and that the combined evaluation of fine needle aspiration plus intranodular and extranodular fine needle biopsy is the most accurate approach.(ABSTRACT TRUNCATED AT 250 WORDS)

[A case of intestinal schistosomiasis with hepatic involvement: interdisciplinary diagnostic approach and peculiarity of the echographic and histologic findings]. / Un caso di schistosomiasi intestinale con interessamento epatico: approccio diagnostico interdisciplinare e peculiarità dei reperti ecografico e istologico.

We report a case of intestinal schistosomiasis; secondary hepatic involvement is particularly described, with a very distinctive ecographic feature of portal hypertension and a bioptic picture stressing a granulomatous periportal inflammation. In the work we emphasize the importance of a multidisciplinary approach (physicians working in the fields of internal medicine, infectious disease, gastrointestinal diseases, radiologist, pathologist) in the course of diagnostic investigation. Finally, we confirm the effectiveness of praziquantel against Schistosoma mansoni.
