[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. This makes recidivity frequent. The recidive cancer involves the hilus of the liver, compresses the surrounding organs and develops different complications.

METHODS

37 patients underwent surgical resection in the 1st Surgical Department of Semmelweis University in the last ten years. Complete tumour-free surgical margins were found in only 48.6% of the cases. The mean follow-up was 23.2 (8-47) months.

RESULTS

9 patients were treated for complication caused by local recurrence. These were mechanical jaundice (9 cases), bleeding oesophageal varices (2 cases), gastric outlet obstruction (2 cases), liver abscess (3 cases) and pain caused by the infiltration of the coeliac ganglion (3 cases). Most part of the complication could be solved by minimal invasive therapy (percutane transhepatic endoprosthesis or drainage, endoscopic sclerotherapy, ultrasound-guided drainage, percutane blockade of the celiac ganglion).

CONCLUSIONS

The fact that resected patients may survive several years as long as patients treated with endoprosthesis and irradiation only survive half a year, has brought a change in the way Klatskin cancer surgery is considered: resection of the tumour should be striven for--even by way of R1 resection. Therefore the risk of recurrence will increase. This is the first article in the literature, which has ever dealt with the complication caused by recidive cancer after resection of Klatskin tumour.
