Comparative study of laparoscopic and open adrenalectomy.

BACKGROUND: Laparoscopic adrenalectomy (LA) had become the preferred operation for management of adrenal neoplasm. We conducted this cohort study to evaluate the outcome of laparoscopic and open adrenalectomy (OA). METHODS: A total of 67 patients with complete medical records were included in this study. Thirty patients underwent OA and the other 37 patients received LA. The intraoperative and perioperative data analyses focused on surgery time, blood loss, pain scale rating, resumption of oral feeding, hospital stay, complications and convalescence. RESULTS: LA was completed in all 37 patients without conversion to OA or mortality. The surgery times (203.4 vs. 192.9, p = 0.776) were similar for both OA and LA groups. There was less blood loss in the LA group (355.0 vs. 104.0, p = 0.021). The postoperative pain scale rating was lower in the LA group (5.6 vs. 4.5 p = 0.035) as was analgesia demand (57.4 vs. 3.7, p < 0.001). Oral feeding resumed earlier in the LA group (91.7 vs. 16.4, p < 0.001) and these patients had a shorter postoperative hospital stay (8.4 vs. 3.9, p < 0.001). The complication rate in both groups was similar. In the LA group, patients with primary aldosteronism had shorter surgery times and less blood loss than patients with other tumor types (p < 0.05). CONCLUSIONS: LA results in good surgical outcome without increased risks. We suggest that LA should be the preferred choice for management of adrenal neoplasms. We also suggest that surgeons inexperienced in LA consider beginning with a case of primary hyperaldosteronism.

Huge maternal hydronephrosis: a rare complication in pregnancy.

A huge maternal hydronephrosis is uncommon in pregnancy and might be mistaken as a pelvic mass. A 21-year-old primigravida was noted at 25th week of gestation to have a visible bulging mass on her left flank. The mass was originally mistaken as a large ovarian cyst but later proved to be a huge hydronephrosis. Retrograde insertion of ureteroscope and a ureteric stent failed, so we performed repeated ultrasound-guided needle aspiration to decompress the huge hydronephrosis, which enabled the patient to proceed to a successful term vaginal delivery. Nephrectomy was performed after delivery and proved the diagnosis of congenital ureteropelvic junction obstruction.
