Hand-Assisted Retroperitoneoscopic Live Donor Nephrectomy: Experience from the First 75 Consecutive Cases

BACKGROUND

The two major life-threatening complications associated with laparoscopic live donor nephrectomy are sudden severe bleeding and intestinal injury. A combined technique-hand-assisted and retroperitoneoscopic (HARS)-reduces the risk of these life-threatening complications. In this study, we report on our experience from the first 75 consecutive HARS operations.

METHODS

The data has been collected prospectively according to intention to treat and includes all consecutive donors operated with the HARS technique. Warm ischemia time, operating time, and blood loss were recorded. Complications, convalescence, and allograft outcome were followed postoperatively with a mean follow-up of 701 (range 60-1438) days.

RESULTS

The mean operating time was 138 (range 85-260) minutes and the mean warm ischemia time 175 (85-510) seconds. The operative time was significantly longer in male donors. The mean bleeding was 176 (50-700) ml. There were no conversions to open surgery. Major complications comprised one pulmonary embolus and one donor required 2 units of blood transfusion. One donor was reoperated due to suspicion of trocar hernia. Nine patients experienced minor complications (fever, n=4; urinary tract infection, n=2; chylous ascites, n=1; orchialgia, n=1; subcostal pain, n=1). All except two kidneys had immediate onset of function. Neither of these could, however, be attributed to the donor operation. One recipient experienced urinary leakage and one a stenosis. Recipient and graft survival were 99% and 96%, respectively.

CONCLUSIONS

We conclude that HARS facilitates the procedure by enabling short operating times and at the same time significantly reducing the risks associated with endoscopic live donor nephrectomy.

Hand-assisted laparoscopic surgery for complex gallstone disease: A report of five cases

AIM: To describe the use of hand-assisted laparoscopic surg-ery (HALS) as an alternative to open conversion for complex gall-stone diseases, including Mirizzi syndrome (MS) and mimic MS.

METHODS: Five patients with MS and mimic MS of 232 consecutive patients undergoing laparoscopic cholecyst-ectomies were analyzed. HALS without a hand-port device was performed as an alternative to open conversion if the anatomy was still unclear after the neck of the gallbladder was reached.

RESULTS: HALS was performed on three patients with MS type I and 2 with mimic MS owing to an unclear or abnormal anatomy, or an unusual circumstance in which an impacted stone was squeezed out from the infundibulum or the aberrant cystic duct impossible with laparoscopic approach. The median operative time was 165 min (range, 115-190 min). The median hand-assisted time was 75 min (range, 65-100 min). The median postoperative stay was 4 d (range, 3-5 d). The postoperative course was uneventful, except for 1 patient complicated with a minor incision infection.

CONCLUSION: HALS for MS type I and mimic MS is safe and feasible. It simplifies laparoscopic procedure, and can be used as an alternative to open conversion for complex gallstone diseases.

Feasibility of robot-assisted totally intracorporeal laparoscopic ileal conduit urinary diversion: initial results of a single institutional pilot study

OBJECTIVES

To explore the use of the da Vinci Surgical Robotic System (DSRS) to assist in the completion of totally intracorporeal laparoscopic ileal conduit urinary diversion (TLIC).

METHODS

Two patients with radiation cystitis underwent TLIC procedures and another patient with bladder cancer underwent TLIC along with laparoscopic radical cystoprostatectomy at our institution. The ileal conduit urinary diversion was done totally intracorporeally using conventional laparoscopic techniques, and the DSRS was used to assist in the Bricker-type ureteroileal anastomosis.

RESULTS

The 3 patients in the study included 2 men and 1 woman (mean age 73 years, range 64 to 84). The TLIC was completed intracorporeally in all 3 patients without the need for open conversion. The operative time, estimated blood loss, intraoperative decrease in hemoglobin, and time to hospital discharge for the 2 patients undergoing TLIC and the patient undergoing TLIC along with radical cystoprostatectomy was 628, 616, and 828 minutes, 50, 200, and 500 mL, 1.7, 2.8, and 5.3 g, and 5, 7, and 10 days, respectively. The median follow-up was 4.5 months (range 3.5 to 5.5). Postoperative satisfactory drainage of both kidneys was confirmed in all 3 patients at 8 weeks or later by intravenous urography or renal nuclear imaging. The serum creatinine remained stable in all 3 patients after surgery at hospital discharge. The only complication noted was postoperative ileus in the patient undergoing radical cystoprostatectomy that resolved with conservative management.

CONCLUSIONS

TLIC is technically feasible and safe and can be done intracorporeally without complications. The DSRS can be successfully used to assist in the completion of TLIC. However, that each case lasted for more than 600 minutes highlights the need for further refinement in the technique. The practical application of TLIC requires improved long-term outcomes compared with open surgery, as well as a reduction in the operative time to justify the costs of robotic surgery.

Robotic cardiac surgery: overview

Most endoscopic procedures are excisional, not reconstructive or microsurgical, mostly because conventional endoscopic instrumentation lacks dexterity due to long, nonarticulated instruments, a fixed pivot point and counterintuitive movement of the instrument tip, and lack of depth perception. Endoscopic approaches to cardiac surgery have not been successful; however, the development of robotic surgical systems has overcome many limitations of endoscopy. Computer-assisted surgery has created a computerized digital interface between the surgeon's hands and surgical instrument tips and enhances surgical ability, thereby enabling endoscopic microsurgery. Recently, robotic systems have allowed cardiac surgeons to perform minimally invasive endoscopic coronary artery bypass grafting (CABG) and valve procedures. This article summarizes the use of robotics in cardiac surgery and discusses its potential in our specialty.

Novel approach to minimizing trocar sites during challenging hand-assisted laparoscopic surgery utilizing the Gelport: trans-gel instrument insertion and utilization

PURPOSE

We present a novel technique for modified application of a hand-assist device, the Gelport (Applied Medical Resources, Rancho Santa Margarita, CA), which uses a gel for intra-abdominal access.

MATERIALS AND METHODS

A 53-year-old woman with a history of rectal cancer treated by abdominoperineal resection, ileostomy, subsequent reanastomosis, chemotherapy, and radiation presented with a 6-cm upper-pole left renal mass. Staging was negative, and a CT scan showed no evidence of lymphadenopathy or renal vein involvement. The patient elected to undergo a hand-assisted laparoscopic radical nephrectomy. Numerous intra-abdominal adhesions were encountered during initial periumbilical hand port placement. The initial adhesions were taken down in an open fashion; however, the proposed trocar sites still could not be exposed. The Gelport was placed, and a laparoscope was passed directly through the established central opening and the gel. A working instrument was then passed through the gel itself, allowing adhesiolysis under direct laparoscopic vision.

RESULTS

The nephrectomy was completed laparoscopically in 4 hours and 15 minutes with lysis of adhesion occupying 90 minutes of the operative time. The estimated blood loss was 150 mL. Despite the technical difficulty of the case, the procedure was completed laparoscopically with two standard 12-mm trocars and a 5-mm lateral retraction trocar.

CONCLUSION

The Gelport permits simultaneous insertion of the surgeon's hand and a working laparoscopic instrument. This allows for maximally efficient utilization of the incision made for hand-assist device placement and may minimize the need for additional trocars during challenging laparoscopic cases.
