Objective:
To report a case of large chylous ascytis as a late complication of a laparoscopic nephrectomy for renal tumor.
Methods:
A 62 year old patient was admitted with general deterioration and abdominal distension due to chylous ascites. Abdominal ultrasound and CT led to the diagnosis. Paracentesis confirmed the presence of a large peritoneal chylous fluid effusion.
Results:
The patient was treated by punction and placement of a percutaneous drainage. A large amount of lymphatic fluid was obtained after punction with a progressive decrease. Medical treatment included low sodium and low fat diet, together with medium chain fast absorbing triglycerides, protein supplements, diuretics and somatostatin analogues (octeotride). The patient's progress was satisfactory after several days of treatment.
Conclusions:
Chylous ascites is a rare complication of laparoscopic nephrectomy, but it has a favorable course if managed conservatively. Meticulous clipping of the retroperitoneal lymph vessels is recommended to prevent the formation of chylous ascites, especially when discharging the renal vascular pedicle during nephrectomy or extensive lymphadenectomy.
