Chylous ascites as a complication of laparoscopic nephrectomy
Abstract
Chylous ascites is a rare complication after major retroperitoneal surgery. Recently chylous ascites has developed more often after laparoscopic nephrectomy since that is increasingly done for various indications at many centers. We reviewed our cases of chylous ascites after laparoscopic nephrectomy. Between January 2002 and December 2008 we performed 622 transperitoneal laparoscopic nephrectomies. We retrospectively analyzed factors related to chylous ascites as a complication of laparoscopic nephrectomy. The overall incidence of chylous ascites was 5.1% (32 of 622 cases), including 4 severe refractory cases (0.6%). The difference in incidence by operation type was not statistically different (p = 0.251). Chylous ascites developed more often after left than right nephrectomy (7.3% or 25 of 343 cases vs 2.5% or 7 of 279, p = 0.010). In patients with radical nephrectomy and nephroureterectomy the incidence was higher in those who did vs did not undergo lymphadenectomy (13.9% or 10 of 72 vs 4.0% or 11 of 275, p = 0.027). Only 1 patient underwent explorative laparotomy due to persistent severe chylous ascites despite 8-week conservative management. The other cases were successfully managed conservatively by total parenteral nutri...Continue Reading

Blood Clotting Disorders
Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
