PURPOSE: Venous involvement develops in 5% to 10% of patients with renal cell carcinoma and is generally considered a relative contraindication to laparoscopic radical nephrectomy. To our knowledge we report the initial clinical series of laparoscopic radical nephrectomy for renal cell carcinoma associated with level I renal vein thrombus. MATERIALS AND METHODS: At our 2 institutions 8 patients each underwent laparoscopic radical nephrectomy for level I microscopic renal vein thrombus (group 1) and level I gross thrombus (group 2). In all 8 group 2 patients the level I thrombus was preoperatively diagnosed by computerized tomography. Mean renal tumor size in groups 1 and 2 was 7.8 and 12.4 cm., respectively. After controlling the renal artery the renal vein was secured by firing an endoscopic gastrointestinal anastomosis stapler on its collapsed, uninvolved proximal part adjacent to the vena cava. Intraoperative, postoperative and pathological parameters were assessed in the 2 groups. RESULTS: In group 1 laparoscopic radical nephrectomy was technically successful in all 8 patients. Mean operative time was 3.1 hours, mean estimated blood loss was 382 cc and mean hospital stay was 1.9 days. In 1 patient each a soft tissue and a vascular margin was positive for cancer. At a mean follow up of 19.5 months (range 2 to 36) metastatic disease occurred in 3 cases (38%). In group 2 laparoscopic radical nephrectomy was technically successful in 7 cases with open conversion in 1. Mean operative time was 3.3 hours, mean estimated blood loss was 354 cc and mean hospital stay was 2.3 days. Surgical soft tissue and the renal vein vascular margin of the transected vein were negative for cancer in all 8 cases. At a mean followup of 9.4 months (range 5 to 16) pulmonary metastasis developed in 1 patient (13%). CONCLUSIONS: Although it is an advanced procedure, laparoscopic radical nephrectomy in patients with level I renal vein thrombus is feasible, safe and follows established oncological principles.  相似文献

PURPOSE: Laparoscopic live donor nephrectomy is an emerging technique that has not yet gained widespread acceptance in the transplant community due to perceived technical difficulties. However, the potential advantages of decreasing donor morbidity, decreasing hospital stay and improving convalescence while producing a functional kidney for the recipient may prove to enhance living related renal transplantation. We report our early experience with laparoscopic live donor nephrectomy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 50 consecutive laparoscopic nephrectomies performed from October 1998 to May 2000 and compared them with 50 consecutive open donor nephrectomies, which served as historical controls. RESULTS: Donor age, donor sex and number of HLA mismatches did not differ statistically in the 2 groups. In the laparoscopic and open nephrectomy groups mean followup was 109 and 331 days (p = 0.0001), mean operative time was 234 and 208 minutes (p = 0.0068), mean estimated blood loss was 114 and 193 ml (p = 0.0001), and mean hospital stay was 3.5 and 4.7 days (p = 0.0001), respectively. Average renal warm ischemia time was 2.8 minutes in the laparoscopic nephrectomy group. Serum creatinine did not differ statistically in the 2 groups preoperatively or postoperatively at days 1 and 5, and 1 month. The rate of recipient ureteral complications in the laparoscopic and open nephrectomy groups was 2% (1 of 50 cases) and 6% (3 of 50), respectively (not significant). CONCLUSIONS: Laparoscopic live donor nephrectomy is an attractive alternative to open donor nephrectomy. Laparoscopic nephrectomy results in less postoperative discomfort, an improved cosmetic result and more rapid recovery for the donor with equivalent functional results and complications.  相似文献

PURPOSE: Delayed graft function after live donor transplantation affects 5% to 10% of recipients regardless of procurement technique. This delay in function is associated with an increased risk of rejection and decreased graft survival. In the present study we critically assess allograft recovery to identify the risk factors related to delayed graft function. MATERIALS AND METHODS: We retrospectively reviewed donor and recipient medical records from 100 consecutive laparoscopic live donor nephrectomies from August 1997 to October 2001. Four criteria were used to classify delayed graft function: I) requirement of dialysis in postoperative week 1, II) creatinine 2.5 mg/dl or greater at postoperative day 5, III) time to half peak activity (mercaptoacetyltriglycine renal scan) at postoperative day 5 greater than 12.2 minutes (normal range 1 to 12.2) and IV) time to peak activity (mercaptoacetyltriglycine renal scan) at day 5 greater than 6.5 minutes (normal range 2.1 to 6.5). Patients could qualify for multiple outcome categories. Patients who did not match any of these criteria were classified as having normal renal function (outcome 0). RESULTS: The number of patients in the delayed graft function categories were 5 with outcome I, 14 with outcome II, 39 with outcome III and 24 with outcome IV. There were 23 patients represented in more than 1 category and 59 patients were classified as having normal function. Recipient age, donor/recipient gender relationship, unrelated highly mismatched donors and cold/total preservation time were identified as risk factors related to impaired early renal function recovery. None of the variables related to the laparoscopic technique itself represented risk factors for delayed graft function. CONCLUSIONS: Female donor kidneys into male recipients and highly HLA mismatched donors represent factors that may be controlled by donor selection when feasible. All attempts should be made to decrease cold ischemia time and, therefore, total preservation time. Prolonged carbon dioxide pneumoperitoneum, warm ischemia time, renal artery length or use of right kidney did not adversely affect the functional outcome of the allografts procured laparoscopically.  相似文献

PURPOSE: We present a novel method of kidney retrieval based on a modified Pfannenstiel incision and insertion of the assistant hand into the abdominal cavity without a device for pneumoperitoneum preservation. This maneuver is performed as the last step in pure laparoscopic live donor nephrectomy. Also, we assessed the effect of this technique on warm ischemia time compared with the standard laparoscopic bag retrieval technique. MATERIALS AND METHODS: A total of 70 laparoscopic live donor nephrectomies were performed at our institutions between October 1998 and March 2001. The first 43 cases were completed using an EndoCatch bag device (Auto Suture, Norwalk, Connecticut) for specimen retrieval, while the last 27 were done using a novel manual retrieval technique through a modified Pfannenstiel incision. We retrospectively analyzed the results in regard to warm ischemia time and intraoperative complications related to the procedure. RESULTS: A statistically significant difference was noted in the EndoCatch and manual retrieval groups in regard to warm ischemia time (p <0.001). There were 2 complications related to the EndoCatch device and none related to the manual technique. No differences were detected regarding recipient outcomes. CONCLUSIONS: Manual specimen retrieval after live donor nephrectomy allows shorter warm ischemia time, while saving the cost of an EndoCatch bag or pneumoperitoneum preserving device that would be used during hand assisted live donor nephrectomy. It was shown to be a safe method without increased donor morbidity.  相似文献

PURPOSE: A review of the existing literature showed that the subject of live donor nephrectomy is a seat of underreporting and underestimation of complications. We provide a systematic comparison between laparoscopic and open live donor nephrectomy with special emphasis on the safety of donors and grafts. MATERIALS AND METHODS: The PubMed literature database was searched from inception to October 2006. A comparison was made between laparoscopic and open live donor nephrectomy regarding donor safety and graft efficacy. RESULTS: The review included 69 studies. There were 7 randomized controlled trials, 5 prospective nonrandomized studies, 22 retrospective controlled studies, 26 large (greater than 100 donors), retrospective, noncontrolled studies, 8 case reports and 1 experimental study. Most investigators concluded that, compared to open live donor nephrectomy, laparoscopic live donor nephrectomy provides equal graft function, an equal rejection rate, equal urological complications, and equal patient and graft survival. Analgesic requirements, pain data, hospital stay and time to return to work are significantly in favor of the laparoscopic procedure. On the other hand, laparoscopic live donor nephrectomy has the disadvantages of increased operative time, increased warm ischemia time and increased major complications requiring reoperation. In terms of donor safety at least 8 perioperative deaths were recorded after laparoscopic live donor nephrectomy. These perioperative deaths were not documented in recent review articles. Ten perioperative deaths were reported with open live donor nephrectomy by 1991. No perioperative mortalities have been recorded following open live donor nephrectomy since 1991. Regarding graft safety, at least 15 graft losses directly related to the surgical technique of laparoscopic live donor nephrectomy were found but none was emphasized in recent review articles. The incidence of graft loss due to technical reasons in the early reports of open live donor nephrectomy was not properly documented in the literature. CONCLUSIONS: We are in need of a live organ donor registry to determine the combined experience of complications and long-term outcomes, rather than short-term reports from single institutions. Like all other new techniques, laparoscopic live donor nephrectomy should be developed and improved at a few centers of excellence to avoid the loss of a donor or a graft.  相似文献

BACKGROUND: We compared the results of hand-assisted laparoscopic living donor nephrectomy (LLDN) and conventional open living donor nephrectomy (OLDN). METHODS: The clinical data on 49 hand-assisted LLDN and 21 OLDN on the left side performed at two institutions in Korea from January 2001 to February 2003 were reviewed. Demographic data of donors and recipients were similar in the two groups. RESULTS: There was one conversion to an open procedure due to bleeding in the LLDN group. The median operation times (180 min in LLDN versus 170 min in OLDN) and warm ischemic times (2.5 min in LLDN versus 2.0 min in OLDN) in the two groups were similar. The estimated mean blood loss, duration of hospital stay and complication rate was also similar in the two groups. The LLDN group reported less pain (visual analog scale) postoperatively (4.1 versus 5.3), but this was not significant (P=0.058). The time to oral intake in the LLDN group was significantly longer by an average of 1 day (P=0.001). Return to work was sooner in the LLDN group (4.0 weeks versus 6.0 weeks; P=0.026). The recipient graft function was equivalent between the two groups. Hand-assisted LLDN appears to be a safe and effective alternative to OLDN. CONCLUSION: Our findings suggest that this technique may give the ability provide grafts of similar quality to OLDN, while extending to the donors the advantages of a traditional LLDN procedure.  相似文献

Objectives: To increase awareness of the anatomical variation of the posterior lumbar tributaries of the left renal vein in retroperitoneoscopic left living donor nephrectomy. Methods: A total of 61 cases of retroperitoneoscopic left living donor nephrectomy were carried out from March 2008 to June 2010. The anatomical variations of the posterior lumbar tributaries of the left renal vein in these patients were noted. Results: According to the variation of posterior lumbar tributaries, there were seven types in total, including five main types (accounts for 95.1%, 58/61 cases) and the type of reno‐hemi‐azygo‐lumbar trunk (AZV; accounts for 16.4%, 10/61 cases). According to the number of posterior lumbar tributaries, no lumbar vein covers accounted for 16.4% (10/61 cases), one lumbar vein accounted for 47.5% (29/61 cases), two lumbar veins accounted for 32.8% (20/61 cases) and three lumbar veins accounted 3.3% (2/61 cases). According to the operation time during the process of managing posterior lumbar veins, it was type 4 (AZV) on which the surgeon spent the most time (P < 0.05), and type 5 (no lumbar vein) on which the surgeon spent the least time (P < 0.05). Conclusions: This is the first report of the anatomical variation of the posterior lumbar tributaries of the left renal vein in retroperitoneal laparoscopic left living donor nephrectomy. Detailed knowledge of these anatomical variations will undoubtedly help surgeons to avoid the potential risk of vein damage during nephrectomy and to obtain a longer renal artery for the following renal transplantation.  相似文献

OBJECTIVE

To report on patients with a small renal mass and concomitant calculus or pelvi‐ureteric junction obstruction (PUJO), and to propose an algorithm for minimally invasive management when these conditions coexist, as the success of laparoscopic partial nephrectomy (LPN) depends greatly on the absence after surgery of ureteric obstruction.

PATIENTS AND METHODS

Fifteen (3%) of 548 patients undergoing LPN (November 1999 to May 2005) had concomitant calculus/PUJO; the calculus/PUJO was treated in six, either before (one), during (three) or after (two) LPN, depending on the presence of obstruction. The remaining nine patients were monitored as they had a punctate and unobstructing stone burden.

RESULTS

The mean (range) tumour size was 2.7 (1.4–4) cm, the operative duration 3.8 (2–6) h, the warm ischaemia time 34.8 (22–53) min, and blood loss 237 (50–600) mL. Two patients with concomitant PUJO had a single‐session dismembered Anderson‐Hynes pyeloplasty and LPN. Three patients with smaller stones (5–12 mm) had extracorporeal shock wave lithotripsy, percutaneous nephrolithotomy or or ureteroscopic removal before (one) or after (two) LPN. One patient with a larger 1.6 cm obstructing renal pelvic calculus had laparoscopic flexible pyeloscopy, but the stone was not visualized. At the end of all treatments, the 6‐month tumour‐free and stone‐free rates were 15/15 and 11/13, respectively.

CONCLUSION

Patients with a concomitant small renal mass and calculus/PUJO can be successfully managed in a simultaneous or staged manner using minimally invasive techniques. A management algorithm is presented.  相似文献

Objective: In 2009, 1659 patients with end‐stage renal failure in Hong Kong were waiting for a renal transplant. The overall number of renal transplants carried out locally remains low, with an even lower number being live donor donations. Yet, live donor kidney transplantation yields results that are consistently superior to those of deceased donor kidney transplantation, and laparoscopic donor nephrectomy (LDN) is increasingly accepted worldwide as a safe and preferred surgical option. We aim to evaluate the outcome of LDN in our setting, and to compare with that of deceased donors in this retrospective review. Patients and Methods: A total of 12 patients received LDN over the study period of 2006–2009. Standard left transperitoneal LDN was carried out. Grafts including three with double vessels were prepared using the bench technique. The postoperative outcomes up to 1 year for both the donors and the recipients were studied. Contemporary results for the 47 deceased donor kidneys were studied and compared. Results: All donors had an eventful recovery. The operating time was 225.0 ± 67.4 min. The hospital stay was 5.6 ± 2.3 days. The recipient outcomes including hospital stay and creatinine levels at discharge and 1 year were 11 days, 121 umol/L and 116 umol/L, respectively. Specifically, no ureteric stricture or graft loss was noted at the 1‐year follow up. Recipient complications included haematoma (1 patient), renal artery stenosis (1 patient) and redo of vascular anastomosis (1 patient). In contrast, the deceased donor graft recipients had a hospital stay of 11 days, and creatinine levels of 205 umol/L on discharge and 205 umol/L at 1 year, respectively. The delayed graft function rates for the live donor and deceased donors group were 0% and 14.9%, whereas the 1‐year graft survival rates were 100% and 87.2% respectively. Conclusion: The results showed that the donor morbidity rate was low, as reflected by the short hospital stay. Also, the overall parameters of recipients were good. In particular, no ureteric stricture was noted, and graft survival was 100% at 1 year. Living donor kidney transplant program using the laparoscopic technique is a viable option to improve the pool of kidneys for transplantation.  相似文献

Laparoscopic partial nephrectomy in cold ischemia: renal artery perfusion   总被引:18,自引:0,他引:18  
PURPOSE: Laparoscopic partial nephrectomy represents a feasible option for patients with small renal masses. We describe our initial experience with laparoscopic partial nephrectomy in cold ischemia achieved by renal artery perfusion. MATERIALS AND METHODS: From November 2001 to March 2003 laparoscopic partial nephrectomy in cold ischemia was performed in 15 patients with renal cell carcinoma. Cold ischemia was achieved by continuous perfusion of Ringers lactate at 4C through the renal artery, which was clamped. Tumor excision was performed in a bloodless field with biopsy taken from the tumor bed. The collecting system was repaired if needed. Renal reconstruction was performed by suturing over hemostatic bolsters. RESULTS: All procedures were successfully completed laparoscopically by our new technique. Mean operative time was 185 minutes (range 135 to 220). Mean ischemia time was 40 minutes (range 27 to 101). Estimated mean intraoperative blood loss was 160 ml (range 30 to 650). Entry to the collecting system in 6 patients was repaired intraoperatively. Additional vascular repair was done in 2 patients. There were no significant postoperative complications. Postoperative followup in 8 patients showed that the renal parenchyma was not damaged by the ischemic period. CONCLUSIONS: Our initial experience of incorporating cold ischemia via arterial perfusion into laparoscopic partial nephrectomy shows the feasibility and safety of the technique. We believe that this approach has the potential to make laparoscopic partial nephrectomy for renal cell carcinoma safe and reliable.  相似文献

Laparoscopic donor nephrectomy: the University of Maryland 6-year experience   总被引:20,自引:0,他引:20  
PURPOSE: We determined whether the results of laparoscopic donor nephrectomy warranted expansion of the availability of the technique. MATERIALS AND METHODS: Donor and recipient charts for 738 consecutive laparoscopic living donor nephrectomies have been reviewed. RESULTS: Renal donors were 69% white race and 57% female. Age range was 18 to 74 years. Neither age nor obesity alone were exclusionary criteria. Nephrectomy was left sided in 96%. Donors with body mass index greater than 33 had longer operative times. The extraction site changed from umbilical to suprapubic during the series. Warm ischemia time was 169 seconds. Conversion to open nephrectomy occurred in 1.6% of cases and blood transfusion was required in 1.2%. Major intraoperative complications occurred in 6.8% and major postoperative complications occurred in 17.1% of cases. Hospitalization lasted 64.4 hours. Postoperative donor creatinine was 1.5 times the preoperative level. Recipient serum creatinine averaged 2.0 mg% at 1 week and 1.6 mg% at 1 year. Delayed graft function occurred in 2.6%. However, 9.1% of recipients did not achieve a serum creatinine less than 3.0 mg% within 7 days. The endovascular stapler also created 37 extra arteries for implantation. CONCLUSIONS: Risks of laparoscopic donor nephrectomy to the donor must not be minimized. Rapid conversion to open surgery to control bleeding may be necessary. Nonvascular intraoperative injuries require recognition. Slow bowel function recovery prolongs hospitalization and may indicate unrecognized pancreatitis or small bowel herniation. Surgical technique and complication management have improved. Laparoscopic donor nephrectomy is now routine but still requires an intense level of attention to prevention of complications.  相似文献

PURPOSE: Most surgeons divide the renal vein with a laparoscopic stapler during laparoscopic donor nephrectomy. The right renal vein is usually shorter than the left one and using the stapler on the right side can result in a higher incidence of vascular complications for right kidney recipients. We present our experience with a new technique for hand assisted laparoscopic right donor nephrectomy. MATERIALS AND METHODS: We designed a new vascular clamp to be completely inserted into the peritoneal cavity through the hand port incision in hand assisted laparoscopy. The renal vein with a cuff of the inferior vena cava was then excised. The defect in the inferior vena cava was sutured intracorporeally. RESULTS: A total of 80 kidney donors underwent hand assisted laparoscopic right donor nephrectomy using the new technique. Mean +/- SD operative time was 184 +/- 36 minutes. Operative time was decreased in the last 30 patients to 152 +/- 22 minutes. Intracorporeal suture time on the inferior vena cava was 16 +/- 3 minutes. No intraoperative complications were noted and there was no partial or total graft loss. Mean blood loss was 50 +/- 35 cc. Mean warm ischemia time was 4 +/- 2 minutes. Hospital discharge was on postoperative day 1 or 2 in 81% of patients. Graft function was normal in 78 recipients with a day 5 postoperative serum creatinine of 1.6 +/- 0.9 mg/dl. Two recipients showed delayed graft function and were treated medically. CONCLUSIONS: This technique for hand assisted laparoscopic right donor nephrectomy has proved to be safe and reproducible. We recommend practicing laparoscopic inferior vena cava suturing in the animal laboratory before performing it in humans.  相似文献

Laparoscopic donor nephrectomy (LDN) has been proven feasible in overweight individuals, but remains technically challenging. As the perirenal fat distribution and consistency significantly differ between men and women, we investigated possible differences between the genders. Prospectively collected data of 37 female and 39 male donors with a body mass index (BMI) over 27 who underwent total LDN were compared. Ninety-one donors with a BMI <25 served as controls. Clinically relevant differences were not observed between men and women of normal weight. In overweight donors, two (5%) procedures were converted to open in females and five (13%) in males. None of these conversions in females, but four conversions in males, appeared to be related to the donor's perirenal fat (P = 0.05). Operation time (median 210 vs. 241 min, P = 0.01) and blood loss (median 100 vs. 200 ml, P = 0.04) were favorable in female donors. The number of complications did not significantly differ. Total LDN in overweight female donors does not lead to increased operation times, morbidity or technical complications. In contrast, the outcome in obese males seems to be less advantageous, indicating that total LDN in overweight women can be advocated as a routine procedure but in obese men reluctance seems justified.  相似文献

PURPOSE: Laparoscopic nephrectomy for living renal transplantation has emerged as the gold standard. Nevertheless, experience with this technique for procuring right kidneys is limited. We report our single institution results of pure laparoscopic right donor nephrectomy. MATERIALS AND METHODS: Laparoscopic donor nephrectomy was initiated at the our institution in November 1999. Patient selection was initially limited to the left kidney but right surgery was started 2 years later after 97 operations had been performed. We prospectively acquired data on the donor and recipient, and specifically analyzed outcomes of the right kidneys. RESULTS: In a 40-month period 300 laparoscopic donor operations were performed. Overall 44 procedures (15%) were on the right side with the fraction greater (22%) after removing exclusion of the right kidney from laparoscopic selection criteria. In this cohort mean operative time was 170 minutes, significantly less than the 190 minutes for 50 contemporaneous left kidneys (p = 0.001). No case of right donor nephrectomy required open conversion and vessels were of adequate length. Donor and recipient complications were similar in the 2 groups without technical graft loss in the entire series. CONCLUSIONS: Our method of laparoscopic right donor nephrectomy yields excellent graft quality with adequate vascular length and without the need for elaborate modifications or hand assistance. Moreover, the right operation is technically easier and it achieved comparable donor morbidity and recipient renal function. With sufficient experience the right kidney should be procured laparoscopically when indicated.  相似文献

Serum creatinine‐based estimates of glomerular filtration rate (GFR) are inaccurate in healthy individuals. Therefore, their use in assessment prior to live donor nephrectomy has been restricted. There are less data on their use postdonor nephrectomy. This study assessed three GFR estimates against Cr51 EDTA radioisotope GFR (iGFR) in the same cohort of patients before and after donor nephrectomy. A total of 206 patients underwent iGFR measurement prior to donor nephrectomy and this was repeated in 187 patients 6–8 weeks postsurgery. The iGFR was compared with the modification of diet in renal disease (eGFR), Cockcroft–Gault (cgGFR) and Mayo Clinic equation (mcGFR) estimates of GFR. Preoperatively, all GFR estimates performed poorly against iGFR; however, mcGFR provided the most reliable estimate. The eGFR underestimated iGFR by 23.60 ± 16.43 ml/min/1.73 m2, cgGFR by 15.54 ± 18.13 ml/min/1.73 m2 and mcGFR overestimated by 0.72 ± 18.11 ml/min/1.73 m2. Postdonation, all estimates again performed poorly, but eGFR and mcGFR outperformed cgGFR. The eGFR underestimated iGFR by 9.13 ± 10.11 ml/min/1.73 m2, mcGFR by 9.44 ± 13.80 ml/min/1.73 m2 and cgGFR overestimated by 6.42 ± 14.49 ml/min/1.73 m2. No GFR estimate performed sufficiently well to supersede iGFR measurement prior to donor nephrectomy. Performance postdonation was little better. In addition, there was no correlation between fall in iGFR and fall in GFR estimates postdonation.  相似文献

Laparoscopic cytoreductive nephrectomy for metastatic renal cell carcinoma   总被引:2,自引:0,他引:2  
OBJECTIVE: To critically analyse the results of laparoscopic cytoreductive surgery for renal cell carcinoma (RCC), as phase III evidence supports cytoreductive nephrectomy before immunotherapy, and there is an overall shift towards minimally invasive renal surgery for this disease. PATIENTS AND METHODS: Since October 2000, 22 patients were treated by laparoscopic cytoreductive nephrectomy for metastatic RCC (group 1). All patients had radiological evidence of metastatic disease, with biopsy confirmation in 10. To put the results into perspective, 25 consecutive contemporary patients with large organ-confined nonmetastatic RCC (>7 cm, clinical stage T2) undergoing laparoscopic radical nephrectomy (group 2) were compared retrospectively. The baseline demographics were comparable between the groups. RESULTS: The mean tumour size was 8 cm in group 1 and 9.6 cm in group 2 (P = 0.07). Variables during and after surgery were comparable between the groups, with a mean operative duration of 3.1 vs 3.2 h (P = 0.82), blood loss of 285 vs 308 mL (P = 0.79), complications in two vs eight (P = 0.08), morphine sulphate equivalent requirements of 51.7 vs 44.1 mg (P = 0.1) and a median length of hospital stay of 1.7 vs 1.6 days (P = 0.68). In group 1 the median (range) time to immunotherapy was 35 (13-136) days. CONCLUSIONS: Laparoscopic cytoreductive nephrectomy is safe and effective in selected patients. Currently the procedure is offered to candidates eligible for immunotherapy and with tumours of < or = 15 cm, and no evidence of adjacent organ invasion or inferior vena caval thrombus. Significant perihilar adenopathy and numerous parasitic vessels can increase the complexity of the surgery. Adequate laparoscopic experience is necessary.  相似文献
