The Impact

Objectives: While the choice of surgical approach for laparoscopic nephrectomy is broadly split between transperitoneal and retroperitoneal options, the evidence for the impact of this decision on perioperative outcomes is built on relatively small volume data, with often inconsistent findings and conclusions. We aimed to assess the impact of operative approach on perioperative outcomes for laparoscopic radical, partial and simple nephrectomy and nephroureterectomy through analysis of the British Association of Urological Surgeons (BAUS) Nephrectomy database. Patients and methods: All patients added to the BAUS Nephrectomy database with laparoscopic surgery between 2012 and 2017 inclusively were included and subdivided by operation and surgical approach. Preoperative patient and tumour characteristics, as well as intraoperative and post-operative short-term outcomes, were assessed. Results: Overall, 26,682 operations were documented over the review window (81.6% transperitoneal). Small increases in blood loss ( p = 0.001), transfusion rate ( p = 0.02) and operative length ( p = 0.01) were seen for transperitoneal radical nephrectomies and longer hospital stays seen for retroperitoneal procedures (radical nephrectomy p = 0.00l; partial nephrectomy p = 0.04). Retroperitoneal procedures were associated with increased rates of conversion for simple nephrectomy ( p = 0.02), nephroureterectomy ( p = 0.03) and most notably partial nephrectomy (10.5% versus 4.4%; p = 0.001). No further variation in intraoperative complications, post-operative complications, tumour margin positivity rates, unintended ITU admission, or likelihood of death was identified related to surgical approach. Conclusion: Observed variations in perioperative outcomes were generally modest in nature, and little ground is seen to support a change in operative technique for those committed to one approach. A caveat to this exists with open conversion for retroperitoneal partial nephrectomies and requires careful consideration of patient selection by the individual surgeon. Level of evidence: 4

698 Background: Increasing cardiovascular disease has led to increases in the patient population on anti-platelet therapy who require urologic surgery. We sought to study perioperative outcomes for those undergoing partial nephrectomy (PN) while taking or not taking perioperative aspirin (pASA). Methods: A retrospective review of those undergoing PN was performed on the Premier Hospital Database from 2003 to 2015, with survey projection weighting resulting in a cohort of 10,807 patients. Two groups were formed – those continued on pASA (group 1, n = 774) and those with no pASA (group 2, n = 10,033). In-hospital complication rates were studied: major bleeding, overall transfusion, day-of-surgery transfusion, prolonged ( > 4 days) length of stay (LOS), and prolonged ( > 285 minutes) operative time. We also assessed 90-day rates of: cardiovascular catastrophe, readmission, major complication, and DVT/PE. Unadjusted rates were calculated for all PN patients and further subdivided into open and minimally invasive PN. Adjusted odds ratios (OR) were then calculated between groups 1 and 2. Results: Group 1 was older (58% vs 38% ≥65 years, p < 0.0001), largely male (73.1% vs 58.7%, p = 0.001), and less healthy (34.8% vs 18.4% with a CCI score ≥2, p = 0.003) than to group 2. For in-hospital outcomes, no significant differences were noted. Stratifying by surgical approach, those in group 1 undergoing minimally invasive PN were slightly less likely to require a day-of-surgery transfusion (OR 0.29, CI [0.05-0.99], p < 0.05). For 90-day outcomes, group 1 were far more likely to suffer a cardiovascular catastrophe (OR 7.56, CI [3.38-16.92], p < 0.001) regardless of surgical approach. Conversely, group 1 was slightly less likely to experience readmission (OR 0.48, CI [0.24-0.94], p < 0.05) and was likely driven by those undergoing minimally invasive PN. Conclusions: This large review of academic and community hospitals provides insight into the impact perioperative ASA has on PN outcomes. As noted, in-hospital outcomes were largely equivalent between groups while 90-day cardiovascular catastrophe rates were much higher in the ASA group. Despite this, this study lends support to the belief that pASA should not be considered an absolute contraindication to PN.

Perinephric Fat

Abstract Background Adherent perinephric fat (APF), characterized by inflammatory fat surrounding the kidney, can limit the isolation of renal tumors and increase the operative difficulty in laparoscopic partial nephrectomy (LPN). The aim of this study was to investigate the predictors of APF and its impact on perioperative outcomes during LPN. Methods A total of 215 consecutive patients undergoing LPN for renal cell carcinoma (RCC) from January 2017 to June 2019 at our institute were included. We divided these patients into two groups according to the presence of APF. Radiographic data were retrospectively collected from preoperative cross-sectional imaging. The perioperative clinical parameters were compared between the two groups. Univariate and multivariate analyses were performed to evaluate the predictive factors of APF. Results APF was identified in 41 patients (19.1%) at the time of LPN. Univariate analysis demonstrated that APF was significantly correlated with the male gender (P = 0.001), higher body mass index (P = 0.002), lower preoperative estimated glomerular filtration rate (P = 0.004), greater posterior perinephric fat thickness (P< 0.001), greater perinephric stranding (P< 0.001), and higher Mayo Adhesive Probability (MAP) score (P< 0.001). The MAP score (P< 0.001) was the only variable that remained an independent predictor for APF in multivariate analysis. We found that patients with APF had longer operative times (P< 0.001), warm ischemia times (P = 0.001), and greater estimated blood loss (P = 0.003) than those without APF. However, there were no significant differences in surgical approach, transfusion rate, length of postoperative stay, complication rate, or surgical margin between the two groups. Conclusions Several specific clinical and radiographic factors including the MAP score can predict APF. The presence of APF is associated with an increased operative time, warm ischemia time, and greater estimated blood loss but has no impact on other perioperative outcomes in LPN.

ABSTRACT Introduction: The introduction of laparoscopic surgery has changed abdominal surgery. We evaluated the evolution and changing trends associated with adoption of laparoscopic liver resection (LLR) and the experience of a surgeon without prior LLR experience. Methods: A retrospective review of 310 patients who underwent LLR performed by a single surgeon from 2011 to 2020 was conducted. Exclusion criteria were patients who underwent laparoscopic liver surgeries such as excision biopsy, local ablation, drainage of abscesses and deroofing of liver cysts. There were 300 cases and the cohort was divided into 5 groups of 60 patients. Results: There were 288 patients who underwent a totally minimally invasive approach, including 28 robotic-assisted procedures. Open conversion occurred for 13 (4.3%) patients; the conversion rate decreased significantly from 10% in the initial period to 3.3% subsequently. There were 83 (27.7%) major resections and 131 (43.7%) resections were performed for tumours in the difficult posterosuperior location. There were 152 (50.7%) patients with previous abdominal surgery, including 52 (17.3%) repeat liver resections for recurrent tumours, and 60 patients had other concomitant operations. According to the Iwate criteria, 135 (44.7%) were graded as high/expert difficulty. Major morbidity (>grade 3a) occurred in 12 (4.0%) patients and there was no 30-day mortality. Comparison across the 5 patient groups demonstrated a significant trend towards older patients, higher American Society of Anesthesiologists (ASA) score, increasing frequency of LLR with previous abdominal surgery, increasing frequency of portal hypertension and huge tumours, decreasing blood loss and decreasing transfusion rate across the study period. Surgeon experience (≤60 cases) and Institut Mutualiste Montsouris (IMM) high grade resections were independent predictors of open conversion. Open conversion was associated with worse perioperative outcomes such as increased blood loss, transfusion rate, morbidity and length of stay. Conclusion: LLR can be safely adopted for resections of all difficulty grades, including major resections and for tumours located in the difficult posterosuperior segments, with a low open conversion rate.

Abstract Background The role of laparoscopic adrenalectomy (LA) in a large adrenal tumor is controversial due to the risk of malignancy and technical difficulty. In this study, we compared the perioperative outcomes and complications of LA on large (≥ 6 cm) and (< 6 cm) adrenal tumors. Methods We retrospectively reviewed all clinical data of patients who underwent unilateral transperitoneal LA in our institution between April 2000 and June 2019. Patients were classified by tumor size into 2 groups. Patients in group 1 had tumor size < 6 cm (n = 408) and patient in group 2 had tumor size ≥ 6 cm (n = 48). Demographic data, perioperative outcomes, complications, and pathologic reports were compared between groups. Results Patients in group 2 were significant older (p = 0.04), thinner (p = 0.001) and had lower incident of hypertension (p = 0.001), with a significantly higher median operative time (75 vs 120 min), estimated blood loss (20 vs 100 ml), transfusion rate (0 vs 20.8%), conversion rate (0.25 vs 14.6%) and length of postoperative stays ( 4 vs 5.5 days) than in group 2 (all p < 0.001). Group 2 patients also had significantly higher frequency of intraoperative complication (4.7 vs 31.3%; adjust Odds Ratio [OR] = 9.67 (95% CI 4.22–22.17), p-value < 0.001) and postoperative complication (5.4 vs 31.3%; adjust OR = 5.67 (95% CI 2.48–12.97), p-value < 0.001). Only eight (1.8%) major complications occurred in this study. The most common pathology in group 2 patient was pheochromocytoma and metastasis. Conclusions Laparoscopic transperitoneal adrenalectomy in large adrenal tumor ≥ 6 cm is feasible but associated with significantly worse intraoperative complications, postoperative complications, and recovery. However, most of the complications were minor and could be managed conservatively. Careful patient selection with the expert surgeon in adrenal surgery is the key factor for successful laparoscopic surgery in a large adrenal tumor. Trial registration: This study was retrospectively registered in the Thai Clinical Trials Registry on 02/03/2020. The registration number was TCTR20200312004.

471 Background: In patients with T3 RCC with venous tumor thrombus reaching the inferior vena cava, without metastatic disease, a nephrectomy with cavotomy is performed. Before 2000, surgical approach of level 3-4 caval tumorthrombus included sternotomy and cardiopulmonary bypass with circulatory arrest, with high morbidity and mortality rates. After the routine use of liver mobilization around 2000, sternotomy became less necessary. We compared perioperative characteristics, complications and survival pre- and post-2000. Methods: We retrospectively studied 91 patients, operated between 1984 and 2016 in a referral hospital. Patients with a T3 RCC and caval thrombus underwent a radical nephrectomy with thrombectomy. Data on patient and tumor characteristics, operation approach, complications (Clavien-Dindo classification), hospital stay, progression and survival were collected and analyzed using Mann-Whitney U, Chi-Square, and Log-Rank tests. Results: 91 patients (56 male) with a mean age of 65 years were included. 33% had a level 3 or 4 cava thrombus. Surgical management before 2000 included sternotomy with circulation arrest in 32% and liver mobilization in 10%. After 2000, the number of sternotomies lowered to 8% while liver mobilization increased to 74%. See table 1 for perioperative outcomes and complications. Disease specific survival was significant longer in patients operated after 2000 (estimated mean 70 vs. 94 months, p = 0.03). Only N stage influenced progression free survival, patients N+ showed worse survival (p < 0.01). Conclusions: The change in surgical approach including liver mobilization significantly decreased complication rates, blood loss, transfusion rate, hospital stay and increased disease specific survival.
