Renal Cyst Excision Through Camera Port Incision

Yoon, Sang Jin

Abstract

PURPOSE: In the treatment of symptomatic renal cysts, sclerotherapy has high recurrence rate. Laparoacopic cyst excision has high success rate but has some limitations concerning expensive devices, CO2 use and requiring trained laparoscopist. We conceived less invasive surgical technique for renal cyst excision.
MATERIALS AND METHODS
The method is as follows. 1) Minimal skin incision of camera port size at PCN site nearest to the cyst. 2) Access to retroperitoneum by Kelly clamp and finger dilatation. 3) Finger dissection with or without ballooning. 4) Aspiration of cystic fluid. 5) Drawing the redundant cyst wall out of the incision. 6) Excision of the redundant cyst wall by open surgical method.
RESULTS
Clinical trials of 5 patients have been performed since March 1999, with a mean age for the patients of 60 years old (range, 56-66), cyst size of 8.3cm (7.7-9.8), wound length of 2.4cm (2.1-3), operation time of 28 minutes (20-35) and blood loss of 1.6 Hb (0.5-3). There was no drain insertion except in one case, and no use of narcotics post op 2 days. Patients were discharged post op 3 days (2-5). There is no evidence of recurrence in short term follow up (mean 8 months, range 3-15).
CONCLUSIONS
Though limited trials, we think expected merits over conventional laparoscopic surgery are better or comparative cosmetic results, no CO2 use, short operation time, less technical expertise and additionally economical advantages. If necessary, conversion to laparoscopic surgery, using the initial incision as camera port is possible during the procedures. So we suggest trial of this method before conventional laparoscopic renal cyst excision.
