EIGHT-YEAR EXPERIENCE WITH TRANSPERITONEAL LAPAROSCOPIC ADRENAL SURGERY:

Portless endoscopic adrenalectomy via a single minimal incision using a retroperitoneal approach: experience with initial 30 cases

AIM

To assess the feasibility of portless endoscopic adrenalectomy via a single minimum incision that narrowly permits extraction of the specimen.

METHODS

For 30 cases of adrenal tumor, portless endoscopic surgery through a single flank incision (3-9 cm; mean, 5.6 cm) was performed without gas inflation or trocar port placement. All of the instruments used during surgery were reusable. The cases included primary aldosteronism (12), Cushing's syndrome (6), preclinical Cushing's syndrome (3), pheochromocytoma (1), non-functioning cortical adenoma (6), adrenocortical carcinoma (1) and adrenocortical hemorrhage (1).

RESULTS

Resection of the tumor was successfully completed, without complications, in all of the cases. Operative time was between 83 and 240 min (mean, 147 min). Estimated blood loss was 5-470 mL (mean, 139 mL). None of the patients required blood transfusion. Postoperative course was uneventful. Wound pain was mild and walking and full oral feeding were resumed on the first and second postoperative day, respectively, in the majority of cases.

CONCLUSIONS

Adrenal tumors are good candidates for portless endoscopic surgery, which is safe, cost-effective, minimally invasive and matches favorably with laparoscopic surgery.

Laparoscopic treatment of adrenal diseases: 10 years on

Since it was initially described in 1992 laparoscopic adrenalectomy (LA) has been gaining popularity amongst urologists and its range of applications has progressively widened. Ten years after the first report of LA this type of operation is presently considered to be the 'standard of care' for most adrenal diseases requiring surgery. We define the current role of laparoscopy in the management of surgical adrenal diseases, using a Medline search (1997-2002) to assess reports of LA, focusing on indications, approaches (transperitoneal and retroperitoneoscopic) and comparative analyses, taking particular care to evaluate operative duration, rate of conversion and transfusion, complications and hospital stay. With both approaches LA is safe and effective and, when compared with open surgery, offers the same functional results with all the advantages of minimally invasive surgery. We conclude that LA based on either approach should be considered the treatment of choice for benign adrenal lesions. Although very promising, conservative surgery and LA should still be evaluated in cases of malignancy.
