The study is to present our two-year experience in transumbilical LESS simple nephrectomy (LESS-SN) for non-functioning kidney, in an effort to evaluate its feasibility, clinical outcomes and potential advantages. Methods: From December 2008 to December 2010, a total of 11 patients with body mass index (BMI) ≤30 underwent transumbilical TriPort TM LESS-SN by a single experienced urologist at our institution. The indications for nephrectomy included nonfunctioning kidney associated with ureteropelvic junctionstricture (n=1), ureteral calculi (n=6), tuberculosis (n=3), and ureteral stricture (n=1). Patient demographics, perioperative and follow-up data were prospectively collected and analyzed. Results: Ten procedures were successfully completed with one patient converted to open surgery due to uncontrollable bleeding. The mean operative time was 189.2 (ranging 100~320 min) with an estimated blood loss of 204.5 (ranging 50-1 000 ml). There were two complications of bleeding (1- intra-, 1- post-). The mean hospitalization after surgery was 7.9 d (ranging 4-17 d). With a regular follow-up of 1, 6, 12, and 24 months after surgery, all patients remained symptom-free with an intra-umbilical scar. Conclusion: Transumbilical LESS simple nephrectomy for nonfunctioning kidney can be accomplished with favorable surgical outcomes and a superiority of cosmesis. However, cases with chronic inflammation are not suitable for initial up-take and should only be attempted by the very experienced laparoscopist.展开更多

Methods: In August 2010 and April 2012, the LESS nephrolithotomy technique was applied to treat two patients with a renal calculus. One patient had a calculus measuring 5 × 3 cm, and the second patient's measured 3 × 3 cm. Both patients underwent general anesthesia. The operations were performed through a retroperitoneal approach with a single-port instrument inserted through the retroperitoneal incision. The standard laparoscopic retroperitoneal technique was performed, and the calculi were removed by incising the area of the thin renal cortex and the renal pelvis, respectively. The operating time, estimated blood loss, intraoperative complications, other complications, drainage time, and post-operative hospital stay were recorded. Results: Both procedures were completed successfully. No additional trocars were added. No conversion to standard laparoscopic or open surgery was needed. The operating times were 130 min and 120 min, and the estimated blood losses were 40 mL and 30 mL. There were no intraoperative complications. The wound drainage times were 3 d and 2 d, respectively and the post-operative hospital stays were 8 d and 7 d, respectively. There was no secondary bleeding or wound infection. Follow-up times were 2 years and 3 months, respectively. No incidence of hydronephrosis was recorded. Conclusions: LESS nephrolithotomy is safe and feasible for treating kidney calculi. It can be applied in patients with large renal calculi and regionally thin renal parenchyma.展开更多

The recovery was uneventful and mean length of postoperative stay was 13 days(12-14 days).At the latest follow-up,all patients remained symptom-free and had normal renal function without evidence of recurrence,and they were delighted for a hidden transumbilical scar.Conclusion:Transumbilical LESS-PN is a feasible and safe procedure albeit extremely technically challenging.Surgical outcomes at a median follow-up of 2 years are promising,while currently it should be reserved for highly selected patients with favorable tumor anatomy and performed by a very experienced laparoscopic surgeon.展开更多

Under these circumstances, the reasonable replacement of a human camera assistant by a mechanical camera holder has resulted in a new surgical procedure termed singleport solo surgery(SPSS). In SPSS, the fixation and coordinated movement of a camera held by mechanicaldevices provides fixed and stable operative images that are under the control of the operator. Therefore, SPSS primarily benefits from the provision of the operator's eye-to-hand coordination. Because SPSS is an intuitive modification of SPLS, the indications for SPSS are the same as those for SPLS. Though SPSS necessitates more actions than the surgery with a human assistant, these difficulties seem to be easily overcome by the greater provision of static operative images and the need for less lens cleaning and repositioning of the camera. When the operation is expected to be difficult and demanding, the SPSS process could be assisted by the addition of another instrument holder besides the camera holder.展开更多

In addition, advanced port systems have enabled to perform concomitant surgical procedures via transumbilical incision. However, combined surgical operations are rarely reported in the literature, particularly in gynaecology. This case report presents a 42-year-old woman who undergo concomitant LESS hysterectomy and nephrectomy due to deep infiltrating endometriosis (DIE) and end stage renal disease. The operation is performed in approximately 3 hours without any complications, and the patient is discharged on postoperative third day. This case demonstrates that complex concomitant operations even in a patient with DIE can be performed using a LESS surgical approach.展开更多

Single-incision laparoscopic cholecystectomy(SILC) has been the most frequently studied SILS to date. Hundreds of studies on SILC have failed to present conclusive results. Most randomized controlled trials(RCTs) have been small in scale and have been conducted under ideal operative conditions. The role of SILC in complicated scenarios remains uncertain. As common bile duct exploration(CBDE) methods have been used for more than one hundred years, laparoscopic CBDE(LCBDE) has emerged as an effective, demanding, and infrequent technique employed during the laparoscopic era. Likewise, laparoscopic biliary-enteric anastomosis is difficult to carry out, with only a few studies have been published on the approach. The application of SILS to CBDE and biliary-enteric anastomosis is extremely rare, and such innovative procedures are only carried out by a number of specialized groups across the globe. Herein we present a thorough and detailed analysis of SILC in terms of operative techniques, training and learning curves, safety and efficacy levels, recovery trends, and costs by reviewing RCTs conducted over the past three years and two recently updated meta-analyses. All existing literature on single-incision LCBDE and singleincision laparoscopic hepaticojejunostomy has been reviewed to describe these two demanding techniques.展开更多
