内镜乳晕小切口男性乳房肥大矫正术

目的探索减少男性乳房肥大整形术后瘢痕,使乳房切除更加精确,更有利于塑形,避免出血、血肿及支配乳头、乳晕感觉神经的损伤。方法对16例患者在内镜监视下,采用乳晕旁2~3.5cm切口,切除肥大的男性乳腺腺体组织,对于以脂肪增生为主者,先行肿胀吸脂术,后在内镜监视下进行残余肥大腺体切除。切除乳腺体组织量单侧为100~320g,平均为130g;吸脂量为20~130ml,平均为68ml,无血肿,切除组织病理检查为脂肪组织及腺体组织。结果术后无血肿,无皮肤坏死,乳头及皮肤的感觉良好,均获随访观察,时间为手术后5个月至3年,无复发。结论内镜外科技术能缩小乳晕切口,避免损伤乳头、乳晕,利于离乳晕较远范围的乳腺组织切除及乳房重新塑形,为男性乳房肥大矫正的一种良好选择。

Minimum incision endoscopic nephrectomy for giant hydronephrosis

Five consecutive patients with symptomatic giant hydronephrosis underwent minimum incision endoscopic nephrectomy. The originally huge renal specimen was retroperitoneally mobilized using both of endoscopy and direct vision, without the use of trocar ports or gas insufflation, via a single minimum incision that narrowly permitted extraction of the specimen. The specimen was successfully extracted from the incision in all patients. Technically, proper deflation of the hydronephrotic sac facilitates mobilization and enables extraction of the specimen. Median (range) size of incision, operative time, and estimated blood loss were 4 cm (3-5), 205 min (156-222), and 210 mL (110-350), respectively. No patient required blood transfusion or encountered operative complications. Postoperative convalescence was short and uneventful; all patients resumed oral intake and ambulance on the day following surgery, and were physically dischargeable from hospital after 2-3 postoperative days. Thus, this technique is a feasible, minimally invasive and safe procedure for symptomatic giant hydronephrosis.     

Sequential bilateral minimum incision endoscopic radical nephrectomy in dialysis patients with bilateral renal cell carcinomas

Since 1998, we have performed minimum incision endoscopic surgery (MIES) for renal cell carcinoma (RCC). For seven dialysis patients with bilateral RCC, we have performed sequential bilateral MIES radical nephrectomy. It was carried out by retroperitoneal approach through a single minimum incision that narrowly permitted extraction of the specimen using endoscopy and direct stereovision, without trocar ports, without gas insufflation and without the insertion of the hands of operators into the operative field. Although six of the seven patients had multiple complications in addition to chronic renal failure (CRF), bilateral kidneys were successfully removed by sequential MIES radical nephrectomy without major operative complication. Postoperative recovery was prompt with all patients resuming oral feeding and walking by the second postoperative day. Sequential bilateral MIES radical nephrectomy, leaving the peritoneal cavity intact and without imposing circulatory stress caused by gas insufflation, is a feasible treatment for bilateral RCCs in dialysis patients.     

Mammaplasty: Shape,volume, and scar size

Recently many mammaplasty techniques have been presented with special attention paid to the resulting scar's size and its position. The surgeon should try to hid the scar, and if the inverted T incision is used, its horizontal branch should be as short as possible and kept in the breast area. Neverthelss, excessive concern about the final scar size should not interfere with the final results of the mammaplasty as far as shape, volume and lasting results are concerned. The author presents his experience in mammaplasty with respect to the volume, the shape, and the scar size interrelationships.
