[Laparoscopic surgery of benign liver tumours].

273 patients underwent elective surgical treatment for benign liver lesions at the 1st Surgical Department of Semmelweis University, Budapest, Hungary between 2004 and 2014. Laparoscopic (LAP) interventions were performed in 83 cases. Cyst fenestration in 52, and hepatic resection in 31 cases.

[Verner-Morrison syndrome: a case study].

Verner and Morrison described a syndrome of watery diarrhea, hypokalemia, and achlorhydria (WDHA) in 1958. VIPomas producing high amounts of vasoactive intestinal peptide (VIP) commonly originate from the pancreas. Typical symptoms play a momentous role in the diagnosis of VIPoma.

[Ultrasound-guided central venous catheterization].

Central venous cannulation is frequently used in patients with serious diseases, although it may be unsuccessful and known to have complications in many cases. It is especially true in more complicated cases e.g.

[Minimally invasive interventions in the treatment of pancreatic diseases].

We have used minimal invasive therapy in the treatment of pancreatic diseases for a long time. CT and/or ultrasound guided techniques have been used for the treatment of pancreatic pseudocysts for more than 20 years. The development of technology has also made an opportunity for the extensive use of laparoscopic surgery at patients suffering from pancreatic diseases.

Evaluation and comparison of the clinical, surgical and pathological TNM staging of colorectal cancer.

Background/aims: The aim of our study was to compare the results of clinical, surgical and pathological staging of colorectal cancer.

Methodology: 660 patients with colorectal carcinoma were included in the study. The results of the clinical, surgical and pathological staging were compared.

[Role of minimally invasive interventions in the treatment of complications caused by recidive Klatskin tumors].

Background: The hilar cholangiocarcinoma grows slowly and gives metastases very rarely. The first prominent sign of this cancer is the jaundice. In spite of the small size of the tumour, oncologically radical resection is only feasible--owing to the anatomical position--in approximately 35-50% of the cases.
