Evolution of laparoscopic live donor nephrectomy: a single-center experience with 1510 cases over 14 years

Clip or staple in laparoscopic live donor nephrectomy? A systematic literature review

INTRODUCTION

Ligation of the renal pedicle is a crucial step in laparoscopic renal harvesting. Currently, two devices are widely used: Hem-o-Lok® clips and staplers. Each has its advantages and disadvantages.

METHODS

A systematic literature review was conducted following the PRISMA methodology on PubMed, EMBASE, and Cochrane databases with no time restrictions. Registered in the PROSPERO database (CRD42023460585), the study's primary outcome measures include the failure rate of the ligation tool, conversion to open surgery, rate of severe bleeding, and device-related death. Other secondary variables are also explored. An assessment of the quality of included comparative studies was performed using the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I) tool.

RESULTS

Out of 393 articles identified using our keywords, 32 were included. Overall, clips have a lower failure rate during application, elongate graft vessel length, and are more cost-effective. Staples are associated with a shorter warm ischemia time and lower blood loss. There is no significant difference between the two devices in terms of conversion, severe bleeding, death, and blood transfusion.

CONCLUSION

There is no perfect modality for renal pedicle control during laparoscopic harvesting, as each instrument has its pros and cons. Hem-o-Lok® clips are a safe and cost-effective option, particularly suitable for right-sided harvesting or in cases of vascular variations. However, they are still associated with a risk of secondary displacement with potentially serious consequences. Certain technical tricks can mitigate this risk.

Pure Laparoscopic Donor Nephrectomy: A Single Institution Experience From a Middle Eastern Country

BACKGROUND

Laparoscopic live donor nephrectomy (LLDN) is the most adopted technique for kidney transplantation. Several obstacles preclude brain-dead organ transplantation in the Middle East, going from social and cultural barriers to economical and structural difficulties. To our knowledge, this is the first study to report Lebanese experience with pure LLDN, and kidney transplantation.

METHODS

We included 120 cases of pure LLDN performed at our center. Demographic, perioperative, and immediate postoperative data were analyzed. Surgical particularities of the technique are described.

RESULTS

The reported laparoscopic technique allowed for minimal perioperative morbidity, with an overall complication rate of 3%. Operative time averaged 146 minutes and warm ischemia time averaged 4 minutes. Mean hospital stay was 3 ± 1 days. Postoperative hemoglobin and creatinine showed a mean absolute variation of 0.09 ± 0.06 g/dL for hemoglobin and 0.51 ± 015 μmoles/L increase for creatinine. No Clavien-Dindo III-V complications were recorded.

CONCLUSIONS

Strict adherence to the reproducible pure LLDN technique allowed for the performance of almost 45 cases per year with minimal morbidity and results comparable to similar series.

Two- and three-dimensional laparoscopic donor nephrectomy: a comparative study of a single-center experience

Background

This is the first report on three-dimensional (3D) laparoscopic donor nephrectomy performed in the Central Asian region and Commonwealth of Independent States countries. This study presents the results of our initial experiences of 3D hand-assisted laparoscopic donor nephrectomy (3D-HALDN) in comparison with the outcomes of two-dimensional hand-assisted laparoscopic donor nephrectomy (2D-HALDN) at a single center.

Methods

From 2015 to 2019, 19 3D-HALDN and 19 2D-HALDN procedures were performed at the same center by two surgeons. All 38 procedures used identical techniques. Between-group differences were considered statistically significant at P<0.05.

Results

The baseline characteristics in both groups were statistically comparable (P>0.05). All donors underwent left nephrectomy. Donors who underwent 3D-HALDN had better outcomes than those who underwent 2D-HALDN, as shown by a shorter warm ischemic time (P<0.05), a shorter operative time (P<0.05), and less blood loss (P<0.05). There were no conversions or major complications (according to the Clavien-Dindo classification) in either group. The average drainage duration and postoperative hospitalization were significantly shorter in the 3D-HALDN group (P<0.05). The between-group differences in the mean postoperative creatinine level and glomerular filtration rate were not significant.

Conclusions

The 3D-HALDN approach is more beneficial than traditional 2D-HALDN by providing a shorter warm ischemic time, less blood loss, and shorter durations of drainage and postoperative hospitalization. Postoperative complications and the functional condition of the kidney in donors in the early and late postoperative periods did not depend on the type of laparoscopic donor nephrectomy.

Introducing robot-assisted laparoscopic donor nephrectomy after experience in retroperitoneal endoscopic approach: a matched propensity score analysis

OBJECTIVES

To assess the safety and efficacy of introducing robotic-assisted laparoscopic donor nephrectomy (RALDN) to the standard retroperitoneal endoscopic donor nephrectomy (REDN).

METHODS

Data were collected prospectively from 124 consecutive living kidney donors (93 for REDN subgroup and 31 for RALDN subgroup) from February 2018 to December 2020. Donor baseline demographics, perioperative outcomes and recipient outcomes were recorded, and these parameters were compared between the two subgroups before and after propensity-score matching.

RESULTS

Mean age was 51.1 ± 9.1 years; 42.7% were males; mean body mass index was 22.7 ± 2.4; and there were 109 (88%) left kidneys. The following data of REDN and RALDN was, respectively, recorded: operative time (213 ± 43 versus 216 ± 39 min, p = 0.721), warm ischemic time (4.7 ± 1.2 versus 4.9 ± 1.4 min, p = 0.399), postoperative complications (5.4% versus 6.5%, p = 1), haemoglobin (g/L) drop (9.4 ± 7.2 versus 9.7 ± 6.6, p = 0.836), blood creatinine at 6 month (1.15 ± 0.23 versus 1.13 ± 0.24 mg/dL, p = 0.734) and at 1 year (1.09 ± 0.22 versus 1.17 ± 0.28 mg/dL, p = 0.591). In post-propensity score matched analyses, there was no significant differences between the two groups including intraoperative and postoperative complications.

CONCLUSIONS

RALDN could be safely introduced into a living donor program experienced in laparoscopic donor nephrectomy. The outcomes of our study comparing these minimally invasive techniques are mostly similar in terms of intraoperative and postoperative outcomes for kidney donors.

Kidney Autotransplantation for Renal Artery Aneurysm: Case Series and a Systematic Review

OBJECTIVES

Renal artery aneurysm (RAA) is a rare vascular disease. Kidney autotransplantation (KAT) is the treatment option when endovascular approach is not available. However, the evidence on KAT for RAA is mostly limited to small case series or reports. Here, we describe our 2 center experience of KAT for RAA, and provide the results of our systematic literature review to evaluate the outcomes.

METHODS

A retrospective 2 center study was conducted in patients undergoing KAT for RAA between 2010 and 2018. Moreover, a systematic review was performed on medical databases to evaluate the outcomes of KAT for RAA.

RESULTS

Nine patients were surgically treated at our institutions: eight with laparoscopic nephrectomy (LN), and 1 with open followed heterotopic KAT. All RAAs were ex-vivo reconstructed, and in 3 cases a vein graft was used for reconstruction. There were 2 postoperative major complications including 1 graft loss. In the systematic review, 102 studies with 355 patients were included. In 35 patients (9.9%) a minimal invasive approach was performed. The incidence of postoperative major complications and graft loss was 9.4% and 4.1%.

CONCLUSIONS

Our experiences showed that laparoscopic approach for nephrectomy followed heterotopic KAT was feasible with good postoperative outcomes. KAT is an effective treatment for RAA when endovascular approach is not feasible for interpretation of the outcomes, the quality and sample size of the evidence should be taken into consideration.

Chyle Leak After Robotic Living Donor Nephrectomy: Literature Review And Management

Chyle leak after living donor nephrectomy is a rare complication and is associated with a significant postoperative burden. To the best of our knowledge, only 1 case of chyle leak after robotic living donor nephrectomy has been reported in the literature. In this study, we present our experience with 2 cases of chyle leak: 1 after and 1 during robotic donor nephrectomy. We discuss previously published studies and man - agement options of chyle leak in kidney donors.

An evaluation of the current status of kidney transplant in terms of the type of receipt among Iranian patients

Introduction

With the increasing prevalence and incidence of chronic renal failure leading to advanced kidney disease (ESRD), the use of renal transplant therapy is increasing globally. The aim of this study was to determine the status of kidney transplant in patients during a period of 4–5 years.

Materials and methods

In this retrospective, analytical study, patients undergoing renal transplant at one of the hospitals in northern Iran were studied. The data was collected using a checklist assessing the required information, including the age, sex, place of residence, source of the kidney for transplant (living related, living non-related, deceased), kidney receiving method (donated, purchased), and wait time for a kidney transplant.

Results

A total of 228 patients were included in the study, of which 73.7% were male and 26.3% were female. The average wait time for kidney transplant was 386.22 days. The mean age of patients was 32.7 ± 10.7 years. In addition, living non-related (66.2%) and deceased (14%) were the most and least frequent sources of kidney transplant, respectively. Moreover, 51.8% of all transplanted kidneys were purchased.

Conclusion

Over the past 5 years, there has been a decrease in wait time for kidney transplant in Rasht, Iran. Factors, such as being female, lower age, and living in urban areas, are related to a shorter wait time for kidney transplant. The most common types of kidney transplant are from non-related donors and purchased.

Clips Can be Safely Used for Vascular Control of the Renal Vessels During Laparoscopic Donor Nephrectomy

OBJECTIVE

To review our experience using clips to control the renal vessels during laparoscopic donor nephrectomy (LDN) and determine the safety of this practice.

METHODS

We performed a retrospective review of patients who underwent LDN at our centre January 1, 2007-September 17, 2019. The primary outcome was the rate of complication associated with vascular control of the renal vessels, which included (1) conversion to open to manage bleeding, (2) additional procedures for bleeding, and (3) major bleeding requiring blood transfusion. Secondary outcomes included the rate of renal artery/vein clip dislodgement or crossing, change in hemoglobin, warm ischemia time and the incidence of intra-operative complications and postoperative in-hospital complications.

RESULTS

We included 503 patients who underwent LDN, of which 497 were left sided. The main renal artery was controlled with 3 titanium clips in 489 (97%) cases. The main renal vein was controlled with 2 polymer-locking clips in 478 (95%) cases. For our primary outcome, there were no conversions to open to manage bleeding, no secondary procedures due to bleeding and no major bleeding requiring blood transfusion. Additionally, there were no donor deaths. Regarding our secondary outcomes, there were 5 intraoperative events related to the titanium clips being placed on the renal artery and 1 intraoperative event related to the polymer-locking clips on the renal vein, none of which resulted in any morbidity.

CONCLUSION

Using 3 titanium clips on the renal artery and 2 polymer-locking clips on the renal vein during left LDN is safe and provides excellent vascular control.

Robotic Assisted Living Donor Nephrectomies: A Safe Alternative to Laparoscopic Technique for Kidney Transplant Donation

OBJECTIVE

To review outcomes after laparoscopic, robotic-assisted living donor nephrectomy (RLDN) in the first, and largest series reported to date.

SUMMARY OF BACKGROUND DATA

Introduction of minimal invasive, laparoscopic donor nephrectomy has increased live kidney donation, paving the way for further innovation to expand the donor pool with RLDN.

METHODS

Retrospective chart review of 1084 consecutive RLDNs performed between 2000 and 2017. Patient demographics, surgical data, and complications were collected.

RESULTS

Six patients underwent conversion to open procedures between 2002 and 2005, whereas the remainder were successfully completed robotically. Median donor age was 35.7 (17.4) years, with a median BMI of 28.6 (7.7) kg/m. Nephrectomies were preferentially performed on the left side (95.2%). Multiple renal arteries were present in 24.1%. Median operative time was 159 (54) minutes, warm ischemia time 180 (90) seconds, estimated blood loss 50 (32) mL, and length of stay 3 (1) days. The median follow-up was 15 (28) months. Complications were reported in 216 patients (19.9%), of which 176 patients (81.5%) were minor (Clavien-Dindo class I and II). Duration of surgery, warm ischemia time, operative blood loss, conversion, and complication rates were not associated with increase in body mass index.

CONCLUSION

RLDN is a safe technique and offers a reasonable alternative to conventional laparoscopic surgery, in particular in donors with higher body mass index and multiple arteries. It offers transplant surgeons a platform to develop skills in robotic-assisted surgery needed in the more advanced setting of minimal invasive recipient operations.

Evolution of Laparoscopic Donor Nephrectomy Techniques and Outcomes: A Single-Center Experience with More than 1000 Cases

Background

Laparoscopic donor nephrectomy (LDN) has evolved and has been established as a surgical standard of care for kidney transplantation.

Material/Methods

This study retrospectively reviews 1132 patients who underwent 4 different laparoscopic living-donor nephrectomies: hand-assisted laparoscopic nephrectomy (HALDN), pure laparoscopic donor nephrectomy (PLDN), laparoendoscopic single-site plus 1-port donor nephrectomy (LESSOP-DN), and mini laparoscopic donor nephrectomy (MLDN).

Results

The mean estimated blood loss (EBL) for the HALDN group was meaningfully higher than those of LESSOP-DN and MLDN (57.5±52.2 mL versus 21.0±30.0 mL versus 18.2±28.7 mL) (P<0.001). The EBL for PLDN (53.3±35.3 mL) was also significantly higher than those of LESSOP-DN and MLDN (P<0.001). Length of stay (LOS) for HALDN was longer than that for LESSOP-DN (4.2±1.2 day versus 4.0±1.4 days, P=0.002). There was 1 intraoperative open conversion in the HALDN group and 2 HALDN surgeries that required postoperative exploratory laparotomy. LESSOP-DN had 3 (0.8%) postoperative incisional hernias. For recipients, the results revealed no significant differences between all 4 groups in terms of estimated glomerular filtration rate (eGFR) and the 1-year graft failure rate.

Conclusions

The LESSOP-DN group was associated with a shorter incision length than those of HALDN and PLDN and shorter LOS than that of HALDN. Recipient results showed no meaningful difference regarding laparoscopic donor nephrectomy technique.

Hand-assisted Laparoscopic Nephrectomy: Evaluation of the Learning Curve

BACKGROUND

Hand-assisted laparoscopic donor nephrectomy (HALDN) has rapidly become the best alternative to open nephrectomy for living kidney donation. As more centers continue to adopt the laparoscopic technique, the safety of the initial transplants must be ensured while ascending the learning curve (LC). This study looks to determine the safety of HALDN and to describe the results of the LC in our center.

METHODS

We conducted a retrospective review of 500 HALDNs performed in our center from July 2003 to July 2017. We analyzed demographic and perioperative characteristics and complications during the first postoperative month. We divided HALDNs into 2 groups: before and after completing the LC (50 nephrectomies). For each group, we assessed operating room time, estimated blood loss, length of stay, and complication and conversion rates.

RESULTS

A total of 500 HALDNs were performed in the study period. Of those, 454 were analyzed in the 2 groups. The median operating room time was 2 hours, length of stay was 2 days, and blood loss was 50 cc. The overall rate of complication was 6.8%. There were significant differences between the 2 groups in operating time, blood loss, and length of stay (P < .05). No differences were found in terms of complication (P = .42) and conversion (P = .28) rates.

CONCLUSION

There was a significant decrease in operating time, blood loss, and length of stay in patients who underwent laparoscopic donor nephrectomy by an experienced laparoscopist. However, no differences were found in complication and conversion rates, which suggests that improvement in surgical training can be accomplished without altering the donor safety.

Transition from laparoscopic to retroperitoneoscopic approach for live donor nephrectomy

BACKGROUND

Laparoscopic donor nephrectomy has become the standard of care due to multiple benefits. Currently, there are various techniques employed with two different approaches: transperitoneal (TLDN) or retroperitoneoscopic (RLDN) approach. There is a lack of data to determine which technique is superior, although the RLDN offers an anatomical advantage by avoidance of manipulation of the intraperitoneal organs. The aims of this study were to explore the merits of RLDN to TLDN and assess the learning curve of transition from TLDN to RLDN.

METHODS

From January 2010 to February 2017, 106 live donor nephrectomies were performed: 56 by TLDN and 50 by RLDN. Data on patient demographics, perioperative parameters, analgesic consumption, pain scores, and kidney graft function were collected and analysed. Data were compared with a Student's t test or Mann-Whitney test. A CUSUM analysis was performed to investigate the learning curve.

RESULTS

All live donor nephrectomies were successful with no conversion to open surgery. There was no blood transfusion, readmission, or mortality. No postoperative complications were graded over Clavien II. Kidney function was comparable in both groups. The follow-up period ranged from 3 to 78 months.

CONCLUSION

Retroperitoneoscopic live donor nephrectomy is a safe approach with comparable results to TLDN. RLDN has an anatomical advantage as it avoids manipulating the intraperitoneal organs and retains a virgin abdomen and hence translates to a lower perioperative complication risk.

A Proposed Classification System and Therapeutic Strategy for Chyle Leak After Laparoscopic Living-Donor Nephrectomy: A Single-Center Experience and Review of the Literature

OBJECTIVES

Chyle leak or chylous ascites remains a rare complication after laparoscopic living-donor nephrectomy. Its cause and management have not been well elucidated in the literature. Thus, the aim of this study was to review the incidence of chyle leak/chylous ascites after laparoscopic living-donor nephrectomy in our institute and in the literature to propose a classification system with its associated treatment strategy.

MATERILAS AND METHODS

In this retrospective review of laparoscopic living-donor nephrectomy patients from January 2005 to April 2016, we identified patients with chyle leak/chylous ascites along with the care performed. A proposed classification system based on our experience and literature is described.

RESULTS

Chylous leak developed in 4 donors (2.25%). Of the 4 donors, 3 were treated nonoperatively with diet modification and subcutaneous octreotide injection. One patient required surgical intervention after not responding to second-line therapy with total parenteral nutrition.

CONCLUSIONS

Chyle leak/chylous ascites after laparoscopic living-donor nephrectomy is rare, but a delayed diagnosis may lead to morbidity secondary to malnutrition and immunosuppression. Meticulous surgical dissection is essential to seal the lymphatic tubes during laparoscopic living-donor nephrectomy. The proposed classification system provides a practical and tailored guide to management based on the drainage volume of chyle leak and a guide to the earlier identification of refractory cases.

Can intraperitoneal bupivacaine decreases pain in patients undergoing laparoscopic live donor nephrectomy? A randomized control trial

PURPOSE

To evaluate effect of intraperitoneal bupivacaine on postoperative pain in patients undergoing laparoscopic live donor nephrectomy.

METHODS

Hundred patients undergoing laparoscopic live donor nephrectomy were included in the study and were divided randomly into two groups based on computer-generated randomization chart of fifty each. Patients were made familiar with VAS chart preoperatively. Group A received 20 mL of 0.5 % bupivacaine, while group B patients received 20 mL of 0.9 % normal saline intraperitoneally Postoperatively, patients were assessed based on VAS and requirement of rescue analgesic, hemodynamic parameters and presence of any adverse effects. Student's t test was used for statistical analysis.

RESULTS

At all-time interval, mean pain scores were higher in group B than group A. The difference between the mean pain scores was statistically significant (p < 0.05) at 0, 2 and 4 h. The mean dose of rescue analgesia (pentazocin, 30 mg in one vial) in group A was 33 ± 26 mg which was significantly less as compared to group B where it was 62 ± 28 mg. There was statistically insignificant difference between all cardiorespiratory factories at all-time intervals except for heart rate and mean blood pressure at 0 h in group A as compared to group B.

CONCLUSIONS

Intraperitoneal bupivacaine is a simple, safe, inexpensive method for control of postoperative pain in patients undergoing laparoscopic live donor nephrectomy. Use of the correct dose and concentration of the drug are essential for effective pain control.

Chylous Leakage After a Laparoscopic Live-Donor Nephrectomy: Case Report and Literature Review

Laparoscopic donor nephrectomy is an established operation for organ procurement in living-donor transplant. Minimal access approach for organ procurement from living donors ensures early convalescence and improved patient participation. Chylous leakage is a rare complication of laparoscopic living-donor nephrectomy. Chylous leakage is mostly determined by iatrogenic injury of cisterna chyli and its main tributaries. It may lead to malnutrition and immunologic deficits because of protein and lymphocyte depletion. An 18-year-old woman underwent left-hand-assisted laparoscopic donor nephrectomy for living donor transplant. She developed chylosus leakage in third postoperative day. A conservative manage-ment with total parenteral nutrition total paren-teral nutrition and subcutaneous somatostatin was immediately initiated. The patient had an abatement of drainage daily output in 4 days of therapy. Chylous leakage is a potentially insidious and perhaps misdiagnosed complication of laparoscopic donor nephrectomy. Conservative therapy is effective in most donors and should be initially attempted. Surgical ligatures or fibrin sealants may be indicated in case of refractory chylous leakage before the arising of malnutrition and/or relevant immunodeficiency.
