There is concern about the limitation in right-sided tumour due to the more demanding surgical technique. We aimed to compare right versus left laparoscopic adrenalectomy in terms of operative outcome.


This is a review of medical records from 1999 to 2003 in a district hospital. Patients' records were retrieved from the computer system under procedure name of adrenalectomy (ICD code 07.22). Primary outcome measures included complication and mortality. Other outcome measures included operation time, blood loss and length of stay.


Thirty-two consecutive cases (left = 18 vs right = 14) of laparoscopic adrenalectomy were performed from 1999 to 2003. The median age of patients was 45 years. Twenty-four of them were Conn's Syndrome (left 14 vs right 10). Median size of tumour was 2 cm (range 0.5–5 cm, left = 2 cm vs right = 1.7 cm; P = 0.87; Mann–Whitney U-test). One left-sided tumour was complicated with perinephric haematoma requiring needle aspiration. There was no operative mortality in both groups. There was no difference in operation time (median time; left = 127 min vs right = 120 min; P = 0.91). There were two conversions (right = 1 vs left = 1) due to bleeding and unclear anatomy. The majority of them had minimal blood loss with none above 200 mL. All patients resumed full diet and were ambulatory within 2 days after the operation. There was no difference in hospital stay (right 4.5 days vs left 5 days; P = 0.28 Mann–Whitney U-test). There was no significant difference between the outcomes of left and right-sided tumour.


There is no difference in clinical outcomes between left and right laparoscopic adrenalectomy.
