RESUMEN
Objective To explore the causes,management and prevention of major blood vessel injury during urological laparoscopic surgery.Methods Six cases of major blood vessel injuries happened in 1700 laparoscopic surgeries from January 2007 to July 2011.All of the cases were males.Patient age was (53 ± 14) years.There were 4 extraperitoneal and 2 transperitoneal procedures including 3 adrenalectomies,1 radical cystectomy,1 radical prostatectomy and 1 radical nephrectomy.There were lacerations in 3 cases of vena cava,2 cases of external iliac vein and one case of renal vein.The length of laceration was (0.68 ±0.29) cm and blood lost was (114 ++ 79) ml.Results Five of the patients were managed with laparoscopic techniques by suction compressing bleeding sites,dissecting related vessels,adding extra trocar and repairing laceration by suturing in four cases and clipping bleeding site in one case.The bleeding control management lasted (21.0 ± 5.6) min.One laparoscopic adrenalectomty for the treatment of pheochromocytoma converted to open surgery because of increasing blood pressure.All the patients were followed up for (4 ± 2) months.No more related complication occurred.Conclusions Lymph node dissection,local adhesion and energy source are the main causes for blood vascular injuries.This kind of injuries may occur at any stages during a laparoscopic surgery and laparoscopic repairing is safe and feasible.
