Clinical comparison between retroperitoneal laparoscopic modified single-layer adrenalectomy and traditional three-layer adrenalectomy in adrenal mass resection

ObjectiveTo compare the clinical effects between retroperitoneal laparoscopic modified single-layer adrenalectomy and traditional three-layer adrenalectomy in adrenal mass resection.

MethodsForty-three patients with adrenal masses were randomly divided into the observation group(22 cases) and control group(21 cases).The observation group was treated with retroperitoneal laparoscopic modified single-layer adrenalectomy.The adrenal central vein was found from the loose and no blood vessel plane of the dorsal psoas major, and the adrenal gland was quickly removed after the central vein was treated.The control group was treated with retroperitoneal laparoscopic conventional three-layer adrenalectomy.The total operation time, time of finding central adrenal vein, amount of intraoperative blood loss, time of removing drainage tube and length of hospital stay were compared between two groups.

ResultsThe retroperitoneal adrenalectomy in 43 cases with adrenal mass were successful, and no open surgery was performed.The total operation time, time of finding central adrenal vein, amount of intraoperative blood loss and length of hospital stay in observation group were less than those in control group(P < 0.05 to P < 0.01).The difference of the time of removing drainage tube between two groups was not statistically significant(P>0.05), and no serious complications occurred in two groups.

ConclusionsBoth surgical methods are safe and effective.The retroperitoneal laparoscopic modified single-layer adrenalectomy can quickly find and treat the adrenal central vein in the early stage, and the anatomical layer is clear.
