Abstract: | n
= 9) should be regarded as a palliative measure. Within a short period, CT-guided aspiration led to recurrence of symptoms
in seven of our patients. Standard treatment of NPHC is fenestration with widest possible excision of the cystic wall, which
can be performed laparoscopically (
n
= 10) or by the conventional surgical mode (
n
= 54). One patient was initially operated by the laparoscopic technique but developed bleeding, which necessitated conversion
to the open mode. Three patients underwent synchronous laparoscopic cholecystectomy. Recurrence rates were similar: 11% in
the laparoscopically treated group and 13% in the group that underwent conventional open surgery. Conventional surgical treatment
was always successful in cases of solitary cysts. However, in cases of multiple cysts measuring more than 5 cm, conventional
surgery was followed by recurrence of symptoms in 26% of patients (7/27), who then had to undergo a second operation. Partial
resection of the liver (
n
= 9) was successfully performed in cases of polycystic disease (
n
= 5) with concomitant enlargement of the organ as well as in cases of large solitary cysts of the left lobe of the liver (
n
= 4). In patients in whom we found that the cysts communicated with the ductal system (
n
= 3), we performed a cystojejunostomy to drain the bile. The complication rate was low. In addition to frequent postoperative
ascites, which necessitated no further intervention, we observed infectious complications in four patients. Twenty patients
(22%) expired during a mean follow-up period of 6.2 years. Interestingly, deaths were frequently associated with malignancy
(11/20). After fenestration of multiple cysts measuring > 5 cm, the patients are at high risk for recurrence. Hence partial
resection of the liver is an excellent therapeutic alternative in selected patients with polycystic disease and massive enlargement
of the organ in whom the disease could not be controlled by simple fenestration. The results of this study show that laparoscopic
fenestration should replace the conventional surgical technique as the gold standard in cases of NPHC because the laparoscopic
technique is less stressful for the patient and is associated with a rate of success similar to that of the conventional technique. |
