Objective: To compare the clinical efficacy of open surgery, peritoneal laparoscopic excision and retroperitoneal laparoscopic excision for adrenal pheochromocytoma. Methods. We retrospectively ana-lyzed the clinical data of 54 patients with adrenal pheochro-mocytoma (27 males and 27 females). Patients' age ranged from 19 to 71. The diameter of tumors ranged from 1.5 to 7.0 cm. Fifty patients had symptoms of hypertension and their course of disease ranged from 2 months to 15 years. None of the patients had inva-sion and metastasis in surrounding organs. According to modus operandi, the patients were divided into 3 groups. The 20 patients in group A underwent open surgery, the 16 patients in group B underwent peritoneal laparoscopic excision, and the 18 patients in group C underwent retroperitoneal laparoscopic excision. The surgical duration, volume of blood loss, severe blood pressure fluctuation, recovery time of intestinal function,postoperative hospital stay, and decrease of blood pressure were compared among the three groups. The re-sults were statistically analyzed. Results: All surgeries were successful, with no complications. All specimens were proved pheochromocytoma. The mean surgical duration was 120.60±18.18 min in group A, 105.13±17.46 min in group B, and 102.22±16.01 min in group C. The volume of blood loss was 146.50±36.20 mL in group A, 116.56±37.32mL in group B, and 120.28±33.80mL in group C. Twelve cases in group A, 5 cases in group B and 5 cases in group C had blood pressure fluctuation. The recovery time of intestinal function was 2.40±0.79 d in group A, 1.75±0.45 d in group B, and 1.58±0.49 d in group C. The postoperative hospital stay was 11.15±1.87 d in group A, 5.94±0.85 d in group B, and 5.94±0.80 d in group C. There was statistical signifi-cance between group A VS group B and group C (P<0.05). There was no statistical significance between group B and group C. There were 18, 15 and 17 cases in group A, B and C who had postoperative decrease of blood pressure, with no statistical difference among the three groups (P>0.05). All cases were followed up for 9 months to 6 years, with no recurrence. Conclusion: Peritoneal laparoscopic excision and retroperitoneal laparoscopic excision can be considered as the preferred choice for adrenal pheochromocytoma, with mini-mal invasion, fast recovery, and satisfactory safety.

Objective To discuss the treatment choices of varicocele by laparoscopic. Methods Retrospective analysis clinical datas of 337 patients with primary varicocele above grade Ⅱ.All of them were treated by operation and followed-up,238 cases had scrotum pain.265 cases were infertility after married.History of diseases was between 1-13 years.249(197 patients with infertility)were treated with laparoscopic high selective ligation of spermatic veins,as Group A.88(68 patiets with infertility)were treated with laparoscopic cluster ligation,as Group B.The clinical data were compared. Results Three hundreds and thirty-seven cases were followed-up 2 years after operation.The operative times of two groups were(38.04±10.9)min、(19.04±7.5)min,the incidences of hydrocelewere 0.4%(1/249),11.3%(10/88);theincidences oftesticular atrophywere 0%(0/249),3.4%(3/88);the improving rates of semen quality in 3 months were 77.1%(192/249),62.5%(55/88);the spontaneous pregnant rates of his spouses in 2 years were 56.8%(112/197),39.7%(27/68).There were significant differences among the 2 groups(P<0.05).The recurrence rates were 5.6%(14/249),4.5%(4/88),there was no significant difference among the 2 groups(P>0.05). Conclusion Laparoscopic high selective ligation of spermatic veins in this study had less complications,higher improving rates of semen quality and pregnant rates.
