Demographic characteristics, tumor size, operative parameters, pathology, postoperative hospital stay, and recorded complications were summarized. There was no open-surgery comparison group. Associations were exploratory.</span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:112%"><span new="" roman="" style="font-family:" times=""><span style="color:black"><b>Results: </b>The cohort included 29 women and 7 men; mean age was 42.44 &plusmn; 12.82 years. Mean tumor diameter was 6.96 &plusmn; 2.81 cm (range 4&ndash;14), although the measurement source was unspecified. Mean operative time was 161.11 &plusmn; 20.80 minutes and mean postoperative stay was 3.91 &plusmn; 1.74 days. Pheochromocytoma and adrenal cyst each accounted for 17 cases (47.2%). Five patients (13.9%) had events recorded as hypertensive crisis, four (11.1%) sustained renal-vein injury, and two (5.6%) had postoperative surgical-site hernia. All renal-vein injuries were repaired laparoscopically; no conversion or transfusion was reported. Mean BMI was higher in patients with intraoperative complications (26.37 &plusmn; 1.72 versus 24.68 &plusmn; 2.00 kg/m&sup2;; P = 0.030). Complication severity could not be reliably classified from the available information.</span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:112%"><span new="" roman="" style="font-family:" times=""><span style="color:black"><b>Conclusion: </b>Laparoscopic adrenalectomy was completed without conversion in this selected series, but clinically relevant intraoperative events occurred. The uncontrolled design and incomplete outcome definitions preclude conclusions about superiority to open surgery, safety across tumor sizes, or oncologic effectiveness. The BMI association requires confirmation.</span></span></span></span><br> &nbsp; Laparoscopic adrenalectomy, Adrenal mass, Pheochromocytoma, Complications, Retrospective study, Iran 35 42 http://tbsrj.mazums.ac.ir/browse.php?a_code=A-10-3548-9&slc_lang=en&sid=1 Mahdi Younesi Rostami dr.mehdiyounesi@gmail.com 100319475328460032212 100319475328460032212 No Nadali Mousanejad moosanejad@gmail.com 100319475328460032213 100319475328460032213 Yes Koushyar Baki amiraimhope@gmail.com 100319475328460032214 100319475328460032214 No Mahla Hosseinzade mahla.hosainzade82@gmail.com 100319475328460032215 100319475328460032215 No Samira Ramezani Abdellahiamirsaleh@gmail.com 100319475328460032216 100319475328460032216 No
