Evaluation of the economic impact of the robotic approach in major and postero-superior segment liver resections: a multicenter retrospective analysis.

Background: Economic impact of robotic liver surgery (RLS) is still a debated issue due to the heterogeneity of liver resections considered and the lack of a rigorous methodology. Therefore, the aim of this study is to perform a time-driven activity-based costing (TD-ABC) comparing the costs of RLS, laparoscopic liver surgery (LLS) and open liver surgery (OLS) in the context of complex liver resections and to compare short term perioperative outcomes. Methods: The institutional databases of two Italian high volume hepatobiliary centres were retrospectively reviewed from February 2021 to April 2022. Patients submitted to major hepatectomies or postero-superior liver resections were selected and divided into three groups according to the approach scheduled (RLS, LLS and OLS) and compared. Major contributors of perioperative expenses were calculated using the TD-ABC model and accurately quantifying each unit resource consumed per patient and the time spent performing each activity. A primary intention-to-treat analysis (ITT-A) including conversions in the RLS and LLS groups was performed. Results: Forty-seven RLS, 101 LLS and 124 OLS were collected. LLS and RLS showed reduced blood loss, morbidity, mortality and hospital stay compared with open. A trend towards reduced conversion rate in RLS compared to LLS was registered. Total costs associated with RLS were estimated at €10,637 vs. €9,543 for LLS and vs. €13,960 for OLS. The higher intraoperative costs associated with RLS (+153.3% vs. OLS and +148.2% vs. LLS, P<0.001), primarily related to surgical equipment expenses, were slightly offset by the postoperative savings (-56.0% vs. OLS and -29.4% vs. LLS, P<0.001) resulting from significantly reduced hospital stays. Conclusions: RLS offers economic advantages over OLS, as initial higher costs are offset by better perioperative outcomes. The evolving robotic marketplace is expected to drive down RLS costs, promoting widespread adoption in minimally invasive procedures. Despite its higher costs than LLS, RLS's ability to enhance minimally invasive feasibility makes it a preferred choice for complex cases, reducing the need for conversions.

Robo-Lap Approach Optimizes Intraoperative Outcomes in Robotic Left and Right Hepatectomy.

Background: The aim of the present study is to evaluate the possible advantages of the Robo-Lap (parenchymal transection by laparoscopic ultrasonic dissector and robotic bipolar forceps and scissors) compared with pure robotic technique (parenchymal transection by use of robotic bipolar forceps and scissors) in major anatomical liver resections with specific focus on intraoperative outcomes. Methods: Major liver resections performed by robotic approach between February 1, 2021 and March 31, 2023 were stratified into two groups according to the approach used to address the phase of liver transection; Pure Robotic Group (n = 21) versus Robo-Lap Group (n = 48). The two groups were compared in terms of intra- and postoperative outcomes and in terms of rate of achievement of intraoperative textbook outcomes. Results: Conversion rate was similar between the two groups while incidence of adverse intraoperative events (according to Satava classification) was higher in the Pure Robotic compared with the Robo-Lap group (85.7% vs 39.6%, p < 0.001). Time to perform parenchymal transection was significantly shorter in the Robo-Lap group (180 min) compared with the Pure Robotic Group (240 min), p = 0.003. Intraoperative textbook outcomes were achieved in a lower proportion of patients in the Pure Robotic compared with the Robo-Lap group. Conclusion: Outcomes of the present study suggest a favorable role of the Robo-Lap approach in robotic major resections as it allows an improvement of the intraoperative results, a greater probability of an uneventful conduction of the procedure, and therefore, better management of the operating room time.

A "cui prodest" evaluation on the development of a minimally invasive liver surgery program: a differential benefit analysis of open and laparoscopic approach for left and right hemihepatectomies.

BACKGROUND: The correlation between technical feasibility and short-term clinical advantage provided by laparoscopic over open technique for major hepatectomies is unclear. This monocentric retrospective study investigates the possible differences in the benefit provided by minimally invasive approach between left and right hepatectomy, deepening the concept of differential benefit in the setting of anatomical major resections. METHODS: All hemihepatectomies performed from January 2004 to December 2021 were identified in the institutional database. A propensity score method was used to match minimal invasive (MILS) and open pairs in the left hemihepatectomies (LH) and right hemihepatectomies (RH) groups with a 1:1 ratio to adjust any potential selection bias. The differential benefit for left and right hepatectomy provided by laparoscopic over open technique was evaluated in a pure analysis (i.e., including cases converted to open) and a risk-adjusted analysis (i.e., after excluding open conversion from the laparoscopic series). RESULTS: The analysis of the risk-adjusted differential benefit demonstrated better result of the MILS in the RH group than in the LH group, in terms of blood loss (∆ blood loss - 150 and - 350, respectively; differential benefit: 200 mL, p < 0.05), morbidity (∆ rate of morbidity - 11.3% and - 18.1%, respectively; differential benefit: 6.8%, p < 0.05) and length of stay, LOS (∆ LOS - 1 day and - 3 days, respectively; differential benefit: 2 days, p < 0.05). CONCLUSION: While MILS is associated with improved clinical outcomes both in left and right hepatectomy procedures, the greater advantage provided by laparoscopy was documented in patients undergoing right hepatectomy, i.e. for more technically demanding procedures. A MILS program should include the broadest range of liver resections to ensure the full benefits of the laparoscopic technique.

The failure to rescue factor: aftermath analyses on 224 cases of perihilar cholangiocarcinoma.

The term "failure to rescue" (FTR) has been recently introduced in the field of hepato-biliary surgery to label cases in which major postoperative complications lead to postoperative fatality. Perihilar cholangiocarcinoma (PHC) surgery has consistently high postoperative morbidity and mortality rates in which factors associated with FTR are yet to be discovered. The primary endpoint of this study is to compare the Rescue with the FTR cohort referencing patients' characteristics and management protocols applied. A cohort of 224 consecutive patients undergoing surgery for PHC, between 2010 and 2021, was enrolled. Perioperative variables were analyzed according to the severity of major postoperative complications (Clavien ≥ 3a). Kaplan-Meier survival analyses were performed to determine complications' impact on survival. Major complications were reported in 86 cases (38%). Among the major complications' cohort, 72 cases (84%) were graded Clavien 3a-4 (Rescue group), while 14 (16%) cases were graded Clavien 5 (FTR group). Number of lymph-node metastases (OR = 1.33 (1.08-1.63) p = 0.006), poorly differentiated (G3) adenocarcinoma (OR = 7.55 (1.24-45.8) p = 0.028, reintervention (OR = 16.47 (2.76-98.08) p = 0.002), and prognostic nutritional index < 40 (OR = 3.01 (2.265-3.654) p < 0.001) rates were independent predictors of FTR. Right resection side (OR 2.4 (1.33-4.34) p = 0.004) increased the odds of major complications but not of FTR. No difference in overall survival was identified. A distinction of perioperative factors associated with postoperative complications' severity is crucial. Patients developing severe outcomes seem to have different biological and nutritional profiles, showing that efficient preoperative protocols are strategic to identify and avert the risk of FTR.

Robo-Lap Approach for Anatomical Resections of Postero-Superior Liver Segments by Indocyanine Green Fluorescence: Intraoperative Navigation Based on Vascular Landmarks.

Cornerstones elements of surgical technique to achieve a good efficacy and safety profile in robotic anatomical resections of postero-superior segments have not yet reached an adequate level of standardization. In this technical note, surgical details to perform anatomical resections of postero-superior segments of the liver (Sg7 and Sg8) based on the identification of vascular landmarks and assisted by use of negative staining with indocyanine green (ICG) fluorescence will be described. In Sg7 segmentectomy, dorsal approach to portobiliary pedicle is suggested, followed by root to periphery approach to right hepatic vein along the negative staining demarcation line by indocyanine green. In Sg8 segmentectomy, root to periphery approach to middle hepatic vein allows comfortable indentification of Sg8 portobiliary pedicle. Approach to right hepatic vein is made easier by negative staining demarcation line. Robo-Lap approach allows to perform these procedures with an adequate level of safety and reproducibility.

Conversion of Minimally Invasive Liver Resection for HCC in Advanced Cirrhosis: Clinical Impact and Role of Difficulty Scoring Systems.

BACKGROUND: Minimally invasive liver resections (MILRs) in cirrhosis are at risk of conversion since cirrhosis and complexity, which can be estimated by scoring systems, are both independent factors for. We aimed to investigate the consequence of conversion of MILR for hepatocellular carcinoma in advanced cirrhosis. METHODS: After retrospective review, MILRs for HCC were divided into preserved liver function (Cohort-A) and advanced cirrhosis cohorts (Cohort-B). Completed and converted MILRs were compared (Compl-A vs. Conv-A and Compl-B vs. Conv-B); then, converted patients were compared (Conv-A vs. Conv-B) as whole cohorts and after stratification for MILR difficulty using Iwate criteria. RESULTS: 637 MILRs were studied (474 Cohort-A, 163 Cohort-B). Conv-A MILRs had worse outcomes than Compl-A: more blood loss; higher incidence of transfusions, morbidity, grade 2 complications, ascites, liver failure and longer hospitalization. Conv-B MILRs exhibited the same worse perioperative outcomes than Compl-B and also higher incidence of grade 1 complications. Conv-A and Conv-B outcomes of low difficulty MILRs resulted in similar perioperative outcomes, whereas the comparison of more difficult converted MILRs (intermediate/advanced/expert) resulted in several worse perioperative outcomes for patients with advanced cirrhosis. However, Conv-A and Conv-B outcomes were not significantly different in the whole cohort where "advanced/expert" MILRs were 33.1% and 5.5% in Cohort A and B. CONCLUSIONS: Conversion in the setting of advanced cirrhosis can be associated with non-inferior outcomes compared to compensated cirrhosis, provided careful patient selection is applied (patients elected to low difficulty MILRs). Difficulty scoring systems may help in identifying the most appropriate candidates.

Robotic Approach for Lymphadenectomy in Biliary Tumors: The Missing Ring Between the Benefits of Laparoscopic and Reproducibility of Open Approach?

OBJECTIVE: This study aimed to evaluate the oncological adequacy of lymphadenectomy (LND) for biliary tumors and surgical outcomes of resections performed using robotic, laparoscopic, and open approaches and to compare the techniques within a weighted propensity score analysis. BACKGROUND: The need to perform formal LND is considered a limit for the applicability of minimally invasive liver surgery. METHODS: Overall, 25 robotic resections with LND (2021-2022) from a single-center constituted the study group (Rob group), matched by inverse probability treatment weighting with 97 laparoscopic (Lap group) and 113 open (Open group) procedures to address the primary endpoint. A "per-period" analysis was performed comparing the characteristics and outcomes of the Rob group with the first 25 consecutive laparoscopic liver resections with associated LND (LapInit group). RESULTS: Minimally invasive techniques performed equally well regarding the number of harvested nodes, blood transfusions, functional recovery, length of stay, and major morbidity and provided a short-term benefit to patients when compared with the open technique. A better performance of the robotic approach over laparoscopic approach (and both approaches over the open technique) was recorded for patients achieving LND with retrieval of >6 nodes. The open approach reduced both the operative time and time for LND, and robotic surgery performed better than laparoscopic surgery. CONCLUSIONS: Minimally invasive techniques are excellent tools for the management of LND in patients with biliary tumors, showing feasibility, and oncological adequacy. Robotics could contribute to the large-scale diffusion of these procedures with a high profile of complexity.

Have we really understood when the efforts of laparoscopic liver resection are justified?-a complexity-based appraisal of the differential benefit.

Background: The implementation of minimally invasive liver resection surgery (MILS) programs starts from procedures with a low degree of technical difficulty. Data regarding the real short-term advantage of laparoscopy according to technical difficulty are still lacking. The aim of the present study is to evaluate the differential benefit of laparoscopic over open technique according to the technical difficulty of the procedures and to investigate if efforts associated with laparoscopic approach are always justified. Methods: Nine hundred and thirty-six MILS resections performed between 2005 and 2018 were stratified according to technical complexity (low, intermediate and high difficulty) and to approach (MILS or open) and matched in a 1:1 ratio using propensity scores to obtain three pairs of groups (Pair 1: Low-MILS and Low-Open, including 274 cases respectively; Pair 2: Int-MILS and Int-Open, including 237 patients respectively; Pair 3: High-MILS and High-Open, including 226 patients respectively). Results: MILS approach resulted in a statistically significant lower blood loss, reduced morbidity, reduced and shorter time for functional recover and length of stay within all pairs. The evaluation of the differential benefit showed a greater advantage of laparoscopic approach in high degree procedures compared with intermediate and low degree, both in terms of blood loss (-250 and -200 mL respectively) and morbidity rate (-5.7% and -4.1% respectively). Conclusions: The favorable biological scenario associated with laparoscopic approach allows to obtain significant benefits in the setting of technically complex procedures. The commitment towards MILS approach should be therefore stronger in this setting, where the advantage of laparoscopy seems to be enhanced.

Portal vein arterialization: a possibility in cholangiocarcinomas infiltrating the right hepatic artery?

Portal vein arterialization (PVA) in advanced cholangiocarcinoma (CCA) is an emerging field of study too little explored despite its potential oncological results. Still to this day, advanced CCA, including peri-hilar (pCCA) and distal (dCCA) CCA, represents a surgical challenge. At diagnosis, CCA is typically associated with extensive infiltration of hilar structures often requiring extended liver and vascular resections that lead to technically complex biliary reconstructions and vascular anastomosis. The rationale behind such radical surgery is to ensure complete tumor resection, with negative margins at final pathology, which remains the only potential curative option. In this scenario, we report a case of advanced CCA, originating from the cysto-choledocal junction, encasing the extrahepatic course of the right hepatic artery (RHA) in which right PVA was carried out to obtain free tumor margins. Considering the technical impossibility to perform a right trisectionectomy due to inadequate future remnant liver (FRL) volume, PVA represented a turning point in the surgical planning of the case. The encouraging postoperative clinical outcomes suggest that PVA should be considered as a valid rescue option to preserve liver inflow in case of locally aggressive HPB malignancies that require extensive resection of the hepatic artery or its branches. This surgical technique can offer an efficient solution in those cases in which the RHA cannot be reconstructed due to its caliber or due to an early subdivision into the right sectorial branches.

Combining Laparoscopic Liver Partitioning and Simultaneous Portohepatic Venous Deprivation for Rapid Liver Hypertrophy.

Future liver remnant (FLR) volume is an important indicator of the risk of posthepatectomy liver failure (PHLF) and limits the feasibility of major hepatectomies. A case series of 5 patients treated with a novel approach is presented. Laparoscopic liver partitioning was combined with subsequent liver venous deprivation (embolization of both the portal and the hepatic veins). Baseline average FLR was 28.8%. All procedures were successfully performed without major complications. Mean 1-, 2- and 4-week hypertrophy of the FLR were 35%, 40.3%, and 46.4%, respectively. Four patients underwent planned surgery after a mean interval of 28 days. Of these, 2 patients achieved sufficient FLR volume and function after 2 weeks and underwent surgery before the 4-week volumetric analysis. One patient did not undergo surgery because of intraoperative diagnosis of peritoneal metastases. No cases of PHLF were observed at 5-day follow-up.

Minimally-invasive Right Hepatectomy for Perihilar Cholangiocarcinoma.

The magnification of images provided by minimally-invasive surgery (MIS) allows a very sharp and precise dissection of the hepatic hilum, allowing to overcome the technical complexity of surgery of perihilar cholangiocarcinoma (PHC). Recently, the feasibility and reproducibility of MIS for PHC are reported: within centers with adequate expertise and respecting the cornerstones of oncological adequacy, it provides short term advantages in a selected population of patients. The video reports the case of a patient with PHC involving the right biliary duct and requiring right hepatectomy with biliary confluence and segment 1 resection, with associated lymphadenectomy. Current evidences, together with feasibility and reproducibility of the technique shown in this video, appear promising and constitute a good prerequisite for the further implementation of this approach to improve patients outcome while following the principles of surgical oncology in hilar cholangiocarcinoma.

Correlation Between Type of Retrieval Incision and Postoperative Outcomes in Laparoscopic Liver Surgery: A Critical Assessment.

Background: At the end of a laparoscopic major hepatectomy, an incision wide enough for specimen retrieval is required. Classically, Pfannenstiel (PF) incision is the type of access favored as service incision in laparoscopy. However, in specific settings the use of a midline (ML) incision can be favorable, with doubtful impaction on the outcomes of a purely laparoscopic operation. The aim of this study was to investigate on clinical outcomes after laparoscopic hemihepatectomies using PF/ML incisions in comparison with open. Methods: The institutional clinical database of the Hepatobiliary Division at San Raffaele Hospital (Milan, Italy) was retrospectively reviewed identifying cases of laparoscopic and open hemihepatectomies. Three analyses were performed: whole laparoscopic versus open; ML versus open; PF versus ML. Clinical outcomes such as intraoperative blood loss, operative time, postoperative morbidity, motility resumption, perceived pain, and length of stay (LOS) were used for comparisons. Results: Laparoscopy was confirmed to be superior to open approach also in the present series in terms of lower blood loss (300 versus 400 mL, P = .041), fewer complications (14.2% versus 25.9%, P = .024), shorter hospitalization (5 versus 7 days, P = .033), and enhanced recovery in terms of better pain control (P = .035) and mobility resumption (P = .047). Similar outcomes were observed comparing ML alone with open (estimated blood loss 300 mL versus 400 mL, P = .039; complications 13.1% versus 25.9%, P = .037; LOS 5 days versus 7 days, P = .04; lower pain perception, P = .048 and faster mobility resumption, P = .046). No significant differences were observed in postoperative outcomes of PF versus ML. Conclusions: Suprapubic and ML incisions at the end of a pure laparoscopic case lead to comparable outcomes between each other. The adoption of ML incision for specimen retrieval does not affect outcomes of minimal invasiveness.

Perioperative and oncologic outcomes of open radical nephrectomy and inferior vena cava thrombectomy with liver mobilization and Pringle maneuver for Mayo III level tumor thrombus: single institution experience.

BACKGROUND: Scarce data are available regarding the technique and outcomes for patients with RCC and Mayo III caval thrombi. The aim of this study was to report surgical and oncological outcomes of RCC patients with Mayo III thrombi treated with radical nephrectomy and thrombectomy after liver mobilization (LM) and Pringle maneuver (PM). METHODS: Retrospective analysis of surgical technique, outcomes and cancer control in 19 patients undergoing LM and PM in a single tertiary care institution were analyzed. RESULTS: Overall, 78% of the patients had performance status ECOG 1 and 58% had a Comorbidity Index >2. Median surgical time was 305 minutes (IQR 264-440). Intraoperative complications were reported for 39% of patients and postoperative complications for 58% (only grade 1 and 2). Intensive Care Unit support was necessary in 16% of the cases. Median length of hospital stay was 9 days (IQR: 7-11). Thirty- and 90-day mortality were 5% and 15%. Two-year overall survival and cancer-specific survival were 60% and 62%, respectively. CONCLUSIONS: We reported surgical techniques, intra- and perioperative complications and follow-up in the largest cohort of RCC patients requiring LM and PM.

Pure laparoscopic right hepatectomy: A risk score for conversion for the paradigm of difficult laparoscopic liver resections. A single centre case series.

BACKGROUND: Converted laparoscopic hepatectomies are known to lose some advantages of the minimally-invasiveness, and factors are identified to predict patients at risk. Specific evidence for laparoscopic right hepatectomy is expected of usefulness in clinical practice, given its technical peculiarities. The purpose of the study was the identification of risk factors and the development of a risk score for conversion of laparoscopic right hepatectomy. MATERIALS AND METHODS: Laparoscopic right hepatectomy performed at a single hepatobiliary surgical center were analyzed. The cohort was split in half to obtain a derivation and a validation set. Risk factors for conversion were identified by uni- and multivariable analysis. A "conversion risk score" was built assigning each factor 1 point and comparing the score with the conversion status for each patient. The accuracy was assessed by the area-under-the-receiver-operator-characteristic-curve. RESULTS: Among 130 operations, 22 were converted (16.9%). Reasons were: 45.5% oncologic inadequacy, 31.8% bleeding, 9.1% adhesions, 9.1% biliostasis, 4.5% anaesthesiological problems. Independent risk factors for conversion were: previous laparoscopic liver surgery (Hazard Ratio 4.9, p 0.011), preoperative chemotherapy ( Hazard Ratio 6.2, p 0.031), malignant diagnosis (Hazard Ratio 3.3, p 0.037), closeness to hepatocaval confluence or inferior vena cava (Hazard Ratio 4.1, p 0.029), tumor volume (Hazard Ratio 2.9, p 0.024). Conversion rates correlated positively with the score, raising from 0 to 100% when the score increased from 0 to 5 (Spearman: p 0.032 in the derivation set, p 0.020 in the validation set). The risk of conversion showed a sharp increase passing from class 3 to 4, reaching a probability estimated between 60 and 71.4%. The score showed good accuracy (area-under-the-receiver-operator-characteristic-curve 0.82). CONCLUSION: Specific risk factors for conversion are identified for laparoscopic right hepatectomy. This score may help in standardizing the choice of a pure laparoscopic or open approach for such challenging resections.

Investigation on the role of biallelic variants in VEGF-C found in a patient affected by Milroy-like lymphedema.

BACKGROUND: Milroy-like disease is the diagnostic definition used for patients with phenotypes that resemble classic Milroy disease (MD) but are negative to genetic testing for FLT4. In this study, we aimed at performing a genetic characterization and biochemical analysis of VEGF-C variations found in a female proband born with congenital edema consistent with Milroy-like disease. METHODS: The proband underwent next-generation sequencing-based genetic testing for a panel of genes associated with known forms of hereditary lymphedema. Segregation analysis was performed on family members by direct sequencing. In vitro studies were performed to evaluate the role of a novel identified variant. RESULTS: Two VEGF-C variations were found in the proband, a novel p.(Ser65Arg) and a pathogenic c.148-3_148-2delCA, of paternal and maternal origin, respectively. Functional characterization of the p.(Ser65Arg) variation in vitro showed alterations in VEGF-C processing. CONCLUSIONS: Our findings reveal an interesting case in which biallelic variants in VEGF-C are found in a patient with Milroy-like lymphedema. These data expand our understanding of the etiology of congenital Milroy-like lymphedema.

Reappraisal of the advantages of laparoscopic liver resection for intermediate hepatocellular carcinoma within a stage migration perspective: Propensity score analysis of the differential benefit.

OBJECTIVE: The aim of the present study was to analyze the outcome of laparoscopic approach specifically in patients with Intermediate-stage disease and to define the differential benefit with Early-stage patients. METHODS: Six hundred twenty-two resections for HCC were dichotomized according to staging (Early and Intermediate) and to approach and then matched in a 1:1 ratio using propensity scores to obtain four groups (E-MILS and E-Open, including 104 patients respectively; Int-MILS and Int-Open, including 142 patients, respectively). The differential benefit associated with the minimally invasive technique was evaluated between intermediate-stage and early-stage patients taking into account blood loss and morbidity rate as outcome indicators. RESULTS: Laparoscopic approach resulted in a statistically significant lower blood loss, reduced morbidity, reduced incidence of hepatic decompensation and shorter time for functional recover and length of stay. The evaluation of the differential benefit showed a greater advantage of laparoscopic approach in Intermediate-stage patients compared with Early-stage patients, both in terms of blood loss and morbidity rate. CONCLUSIONS: The favorable biological scenario associated with laparoscopic approach allows to obtain enhanced benefits in the setting of more advanced liver disease. The push towards minimal invasiveness and the incremental benefit associated with it could potentially promote stage migration in suitable patients.

Perihilar cholangiocarcinoma: are we ready to step towards minimally invasiveness?

The primary endpoint of this study is to evaluate the feasibility and safety of the laparoscopic approach in selected types of PeriHilar Cholangiocarcinoma (PHC). Secondary endpoint is to evaluate the potential advantages of laparoscopic approach over the open counterpart. From 2018, an MILS program for PHC was undertaken in selected patients: 16 patients constituted the study group (out of 261 operated between 2004 and 2019) and was compared with a group of patients operated by open technique (control group) in the previous period through a propensity score matching with a 1:2 ratio. Intraoperative and postoperative outcomes were evaluated and compared, focusing on blood loss, length of surgery, conversion to open approach, and complications. Laparoscopic resections resulted in statistically significant longer procedures (360 vs 275 min, p = 0.048). Conversion rate was 18.8%, being oncological concerns the most frequent reason for conversion (3/3 cases). A lower blood loss (380 vs 470, p = 0.048) and minor intraoperative blood transfusions (12.5% vs 21.9%, p = 0.032) were recorded in the study group. A number of retrieved nodes and rate of R0 resections were similar between the two groups. Patients in the MILS group had shorter length of stay (median 10) compared with open group (median 14), p = 0.048. The laparoscopic approach in PHC, so far maintained in an exploratory phase with the biliary-enteric anastomosis performed through the service incision, demonstrates adequate feasibility and safety standards when conducted in carefully selected patients and in centers with expertise.
