Single-Port Extraperitoneal vs. Multiport Transperitoneal Robot-Assisted Radical Prostatectomy: A Propensity Score-Matched Analysis.

(1) Background: Since the introduction of the purpose-built Single Port (SP) robotic platform, there has been an ongoing debate regarding its advantages compared to the established multi-port (MP) system. The goal of this present study is to compare the perioperative, oncological, and functional outcomes of SP Extraperitoneal robotic radical prostatectomy (RARP) versus that of MP Transperitoneal RARP approach at a high-volume tertiary center. (2) Methods: Based on a retrospective review of the prospectively maintained IRB-approved database, 925 patients successfully underwent RARP by a single experienced robotic surgeon. A 4:1 propensity-matched analysis based on the baseline prostate cancer International Society of Urological Pathology (ISUP) Grade Group, clinical stage, and preoperative Prostate Specific Antigen (PSA) was performed, which yielded a cohort of 606 patients-485 in the SP EP and 121 in the MP TP approaches. Of note, the SP EP approach also included the traditional Extraperitoneal (n = 259, 53.4%) and the novel Transvesical (TV) approaches (n = 226, 46.6%). (3) Results: The overall operative time was slightly longer in the SP cohort, with a mean of 198.9 min compared to 181.5 min for the MP group (p < 0.001). There were no intraoperative complications with the MP approach and only one during the SP approach. The SP EP technique demonstrated significant benefits, encompassing reduced intraoperative blood loss (SP 125.1 vs. MP 215.9 mL), shorter length of hospital stay (SP 12.6 vs. MP 31.9 h), reduced opioid use at the time of discharge (SP 14.4% vs. MP 85.1%), and an earlier Foley catheter removal (SP 6 vs. MP 8 days). From an oncological perspective, the rate of positive surgical margins remained comparable across both groups (p = 0.84). Regarding functional outcomes, the mean continence rates and Sexual Health Inventory for Men (SHIM) scores were identical between the two groups at 6 weeks, 3 months, and 6 months respectively. (4) Conclusion: SP EP RARP demonstrates similar performance to MP TP RARP in terms of oncologic and functional outcomes. However, SP EP RARP offers several advantages in reducing the overall hospital stay, decreasing postoperative pain and hence the overall opioid use, as well as shortening the time to catheter removal, all of which translates to reduced morbidity and facilitates the transition to outpatient surgery.

The Learning Curve for Holmium Laser Enucleation of the Prostate: A Single-Center Analysis of Surgical And Functional Outcomes.

Background: To report the surgical and functional outcomes of the holmium laser enucleation of the prostate (HoLEP) surgical program implemented at a high-volume tertiary referral center and to estimate the learning curve (LC) duration for this surgical procedure. Methods: Data of all consecutive patients undergoing HoLEP at the University of Verona between June 2022 and April 2024 were retrieved from a prospectively maintained institutional database of patients undergoing benign prostatic hyperplasia (BPH) surgical treatment. The primary endpoint was functional outcomes evaluation during the surgeons' LC. The secondary endpoint was to define the surgical LC for HoLEP. A multivariable test of means was performed to compare functional outcomes at different time points. After adjusting for potential confounders (age, preoperative pharmacotherapy, and prostate volume), multivariable linear regression models were fitted to evaluate the effect of experience on operative time (OT) and enucleation efficiency. To assess LCs for HoLEP surgery, the non-risk-adjusted cumulative sum (CUSUM) method was used. Results: A statistically significant improvement in International Prostate Symptoms Score (IPSS) score, delta% IPSS score, IPSS quality of life (IPSS-QoL) score, and delta% IPSS-QoL score was observed over the study period. Furthermore, the incidence of irritative symptoms (p < 0.001) and stress incontinence (p = 0.01) significantly decreased over time, with a 12-month incidence of 8.4% and 9.5%, respectively. A statistically significant association between experience and both OT and enucleation efficiency was observed in multivariable linear regression analysis. The CUSUM chart for OT and enucleation efficiency showed a steep initial upward/downward trend of ∼50 cases each, and a plateau until ∼100 procedures are reached, where the breakpoint is recognized for both variables and where the CUSUM curve goes below the locally weighted scatterplot smoothing curve in the corresponding observed-expected CUSUM plot. Conclusions: HoLEP represents an effective treatment for BPH, demonstrating significant improvement in BPH-related symptoms over the study period, despite the considerable LC of ∼50 cases associated with the procedure.

Disparities in outcomes of colorectal cancer surgery among adults with intellectual and developmental disabilities.

Disparities in colorectal cancer screening have been documented among people with intellectual and developmental disabilities (IDD). However, surgical outcomes in this population have yet to be studied. The present work aimed to evaluate the association of IDD with outcomes following colorectal cancer resection. All adults undergoing resection for colorectal cancer in the 2011-2020 National Inpatient Sample were identified. Multivariable linear and logistic regression models were developed to examine the association of IDD with risk factors as well as outcomes including mortality, complications, costs, length of stay (LOS), and non-home discharge. The study is limited by its retrospective nature and did not capture disease staging or time of diagnosis. Among 722,736 patients undergoing colorectal cancer resection, 2,846 (0.39%) had IDD. Compared to patients without IDD, IDD patients were younger and had a higher burden of comorbidities. IDD status was associated with increased odds of non-elective admission (AOR 1.40 [95% CI 1.14-1.73]) and decreased odds of treatment at high-volume centers (AOR 0.64 [95% CI 0.51-0.81]). Furthermore, IDD patients experienced significantly greater LOS (9 vs 6 days, p<0.001) and hospitalization costs ($23,500 vs $19,800, p<0.001) relative to neurotypical patients. Upon risk adjustment, IDD was significantly associated with 2-fold increased odds of mortality (AOR 2.34 [95% CI 1.48-3.71]), 1.4-fold increase in complications (AOR 1.41 [95% CI 1.15-1.74]), and 6.8-fold increase in non-home discharge (AOR 6.83 [95% CI 5.46-8.56]). IDD patients undergoing colorectal cancer resection experience increased likelihood of non-elective admission, adverse clinical outcomes, and resource use. Our findings highlight the need for more accessible screening and patient-centered interventions to improve quality of surgical care for this at-risk population.

Endovascular Aortic Repair With the E-Tegra Device: Preliminary Outcomes From a Multicenter National Registry.

Endovascular aortic repair (EVAR) is currently expanding its feasibility thanks to design innovations, but hostile proximal necks and narrow iliac arteries are still a constraint, as expressed by the Instructions for Use (IFU) of most devices. Our aim is to report the preliminary results of the E-Tegra endograft in infrarenal abdominal aortic aneurysms (AAAs) performed in 15 high-volume centers. The e-Tegra Italian endoGraft REgistry (TIGRE) is a prospectively maintained database of consecutive EVAR with the E-Tegra stent-graft across 15 participating centers between March 2021 and March 2023. The registry records baseline clinical data, anatomic measurements of the abdominal aorta, perioperative and postoperative outcomes, with a scheduled follow-up period of 3 years for all patients. This is a preliminary analysis of the first results updated to January 2024. The primary endpoints are technical and clinical success, perioperative mortality, freedom from endograft rupture, and aortic-related mortality. The secondary endpoints are freedom from reintervention, and any type of endoleak (EL). The results were analyzed in relation with the anatomic characteristics of the AAAs, namely, iliac axes tortuosity and proximal neck hostility. The registry included 147 consecutive EVAR (138 elective and 9 in emergent setting), 7 of which were associated with an iliac branch implantation. Ninety patients had at least 1 criterion of anatomical hostility, and 25 were treated outside the device IFU. Primary technical success was achieved in 146 cases (99.3%) and assisted success in 147 (100%), with no perioperative mortality. After a median follow-up period of 20 months, no aneurysm-related mortality occurred. Reinterventions were 5: 2 for type IB EL and 3 for type II ELs with aneurysm sac increase. Five more type II ELs with aneurysm sac stability are under observation. No differences in terms of reinterventions were noted between aneurysms with standard and hostile anatomy. The E-Tegra endograft is safe and effective in treating AAAs with standard and hostile anatomy, with a low rate of complications and reinterventions, although longer-term outcomes and larger numbers are needed to compare its performances related to specific anatomic criteria. This multi-center nationwide Registry reports a real-world experience of EVAR performed with the E-Tegra abdominal endograft across 15 high-volume Centers, providing early- and mid-term device-specific results, which will help vascular surgeons in endograft selection. In particular, this study focuses on clinical results obtained in treating aneurysms with hostile anatomy, analyzing the performances of the E-Tegra endograft in cases of hostile proximal necks and narrow or tortuous iliac axes.

Risk factors for reoperation of inflatable penile prosthesis among an ethnically diverse urban population in a high-volume center.

Inflatable penile prosthesis (IPP) is a surgical treatment for erectile dysfunction refractory to medical therapy or for those who desire permanent treatment. Complications like mechanical failure and infection may necessitate reoperation, and patients with certain risk factors remain predisposed to reoperation. We retrospectively analyzed 530 patients undergoing primary IPP implantation at a large, urban, multiethnic hospital with a high volume of IPP implantations. Primary outcomes were reoperation due to any reason and reoperation due to infection. Patient characteristics and intraoperative factors were compared between those requiring reoperation and those not requiring reoperation. Overall, 12.1% of patients underwent reoperation, primarily due to infection, with a median time to reoperation of 4 months. Analysis revealed an increased likelihood of reoperation with Peyronie's disease (OR = 2.47), hemoglobin A1c over 8 (OR = 2.25), active smoking (OR = 2.75), and estimated blood loss (EBL) ≥ 25cc (OR = 2.45). A decreased likelihood of reoperation was observed when Arista™ powder was used intraoperatively (OR = 0.38). Reoperation specifically due to infection was associated with an infrapubic approach (OR = 2.56) and hypertension (OR = 9.12). Our findings confirm smoking and diabetes as risk factors for reoperation, while also providing insights into factors like estimated blood loss and Arista™ powder use. However, long-term survival rates were limited by loss to follow-up. (Clinical trial registration N/A).

Dynamic Assessment of Drain Fluid Amylase Estimates the Risk of CR-POPF Following Pancreatoduodenectomy.

To evaluate whether drain fluid amylase levels on day-1 (DFA1) and day-3 (DFA3) can reliably estimate the risk of clinically relevant-postoperative pancreatic fistula (CR-POPF) following pancreatoduodenectomy (PD) compared to either value alone or in combination with clinicopathologic variables. CR-POPF is a major source of morbidity and mortality following PD. Current drain management algorithms are variable and are mostly dependent on DFA1, while the DFA3 is seldom utilized to guide clinical decision making. Between 2015-2020, patients who underwent PD at two high-volume pancreas centers and had intraoperative drain placement with measurement of DFA1 and DFA3 were retrospectively reviewed. Models to predict CR-POPF were constructed using DFA1, DFA3, fistula risk score (FRS) and other patient or treatment-related parameters. The fittest and more parsimonious model was used to construct a CR-POPF risk calculator. Nine-hundred-twenty-three patients were included in the analysis. The FRS was high in 100(10.9%), intermediate in 524(57.3%), low in 211(23.1%) and negligible in 79(8.6%) patients. The overall rate of CR-POPF was 9.2%. Five logistic regression models were constructed using variables known to be implicated in CR-POPF. A model based solely on DFA1 and DFA3 with a cross-validated area under the curve of 0.846 was selected. A calculator using DFA1 and DFA3 was created based on this model to estimate the risk of CR-POPF. Risk of CR-POPF following pancreatoduodenectomy can be accurately estimated based on measurement of DFA1 and DFA3. Our CR-POPF kinetics calculator can facilitate postoperative risk stratification and guide drain management algorithms.

Molecular markers of proliferation, DNA repair, and immune infiltration defines high-risk subset of resectable retroperitoneal sarcomas

IntroductionFor retroperitoneal sarcomas (RPS), aggressive surgical resection offers the only chance for a cure; however, 5-year survival remains below 65%. Therefore, there is a critical need to identify drivers of poor clinical outcomes. Materials and methodsTo identify biomarkers of tumors likely to recur following curative intent resection, we performed genomic and transcriptomic sequencing for 47 and 34 patients, respectively, with non-metastatic RPS at a single, high-volume sarcoma center. ResultsAt the DNA level, alterations in TERT were associated with poor disease-free survival (DFS) and overall survival (OS). Increased RNA expression of gene sets related to growth signaling and DNA repair were associated with poor DFS and OS. Infiltration of CD8+ T-Cells and activated dendritic cells were associated with poor DFS and OS. ConclusionThese findings may help to better identify and treat non-metastatic, high-risk RPS.

Mesenchymal Tumor Management: Integrating Surgical and Non-Surgical Strategies in Different Clinical Scenarios.

Mesenchymal tumors originate from mesenchymal cells and can be either benign or malignant, such as bone, soft tissue, and visceral sarcomas. Surgery is a cornerstone treatment in the management of mesenchymal tumors, often requiring complex procedures performed in high-volume referral centers. However, the COVID-19 pandemic has highlighted this need for alternative non-surgical approaches due to limited access to surgical resources. This review explores the role of non-surgical treatments in different clinical scenarios: for improving surgical outcomes, as a bridge to surgery, as better alternatives to surgery, and for non-curative treatment when surgery is not feasible. We discuss the effectiveness of active surveillance, cryoablation, high-intensity focused ultrasound, and other ablative techniques in managing these tumors. Additionally, we examine the use of tyrosine kinase inhibitors in gastrointestinal stromal tumors and hypofractionated radiotherapy in soft tissue sarcomas. The Sarculator tool is highlighted for its role in stratifying high-risk sarcoma patients and personalizing treatment plans. While surgery remains the mainstay of treatment, integrating advanced non-surgical strategies can enhance therapeutic possibilities and patient care, especially in specific clinical settings with limitations. A multidisciplinary approach in referral centers is vital to determine the optimal treatment course for each patient.

Validation of the cutoff values for the number of metastatic lymph nodes for esophageal cancer staging: a multi-institutional analysis of 655 patients in Japan.

The number of metastatic lymph nodes (LNs) is an important prognostic factor for esophageal cancer, and N staging is important for prognostic stratification. The optimal cutoff values for clinical (cN) and pathologic N (pN) staging should be reconsidered following advances in neoadjuvant therapy. The study included 655 patients who underwent esophagectomy between January 2014 and December 2016 in four high-volume centers in Japan. Optimal cutoff values for the number of metastatic LNs in cN and pN staging were examined using X-tile, and their prognostic performance was validated using the Kaplan-Meier method. The cutoff values were 1, 2, and 3 for cN staging and 1, 3, and 7 for pN staging. Prognosis was significantly better in patients with cN0 than in those with modified (m)-cN1 (p = 0.0211). However, prognosis was not significantly different among the patients with m-cN1, m-cN2, and m-cN3 disease. Prognosis was significantly different among the patients with pN0, pN1, pN2, and pN3 disease (pN0 vs pN1, p < 0.0001; pN1 vs pN2, p < 0.0001; pN2 vs pN3, p < 0.0001). In patients who received preoperative neoadjuvant therapy, prognosis, which was not significantly different among the patients with cN0, m-cN1, m-cN2, and m-cN3 disease (cN0 vs m-cN1, p = 0.5675; m-cN1 vs m-cN2, p = 0.4425; m-cN2 vs m-cN3, p = 0.7111), was significantly different among the patients with pN0, pN1, pN2, and pN3 disease (pN0 vs pN1, p = 0.0025; pN1 vs pN2, p = 0.0046; pN2 vs pN3, p = 0.0104). cN has no prognostic impact in patients who underwent preoperative treatment followed by esophagectomy, despite the optimization of cN classification. The conventional TNM8th pN classification is useful for predicting prognosis even for patients who have undergone preoperative treatment. The conventional cutoffs for metastatic LNs in the International Union against Cancer tumor node metastasis staging system are valid and can be effectively used in clinical practice.

On-clamp vs off-clamp robot-assisted partial nephrectomy for achieving modified trifecta: inverse probability of treatment weighting analysis from a high-volume tertiary robotic center.

On-clamp partial nephrectomy for the surgical treatment of renal masses poses the risk of ischemia and greater post-operative renal function loss. Conversely, the off-clamp technique might enhance renal function preservation by avoiding any ischemia time. Nevertheless, the debate persists regarding the efficacy of the on- versus off-clamp partial nephrectomy in achieving better surgical, functional, and oncological outcomes. We retrospectively assessed the data from patients undergoing Robot-Assisted Partial Nephrectomy (RAPN) from 2016 and 2023 in a tertiary robotic center. Inverse probability of treatment weighting (IPTW) was used to account for selection bias in treatment allocation. The main objective of the study was assessing the achievement rates of a modified trifecta within the two groups. Multivariable logistic regression analysis (MLRA) was employed to assess the predictors of trifecta achievement. 532 patients were included in the analysis, of whom 74.1% vs. 25.9% underwent on- and off-clamp, respectively. Balancing the two groups for the main predictors of on-clamp surgery, there were no significant differences between on- and off-clamp in terms of estimated blood loss, transfusion rate, intra- and post-operative complications, positive surgical margins, and post-operative mean reduction of eGFR. Finally, no differences were found in the rate of "trifecta" achievement between on-clamp and off-clamp RAPN (24.6% vs. 21%, p = 0.82). At MLRA, off-clamp technique was not a predictor of trifecta achievement compared to the on-clamp technique (off-clamp vs. on-clamp, aOR 1.24, 95% CIs [0.65-2.36], p = 0.58). Our study revealed that clamping technique does not imply clinically relevant differences in reaching trifecta outcomes.

Nationwide cost-effectiveness and quality of life analysis of minimally invasive distal pancreatectomy

BackgroundThis study analyzed the Quality of Life (QoL) and cost-effectiveness of laparoscopic (LDP) versus robotic distal pancreatectomy (RDP).MethodsConsecutive patients submitted to LDP or RDP from 2010 to 2020 in four high-volume Italian centers were included, with a minimum of 12 months of postoperative follow-up were included. QoL was evaluated using the EORTC QLQ-C30 and EQ-5D questionnaires, self-reported by patients. After a propensity score matching, which included BMI, gender, operation time, multiorgan and vascular resections, splenic preservation, and pancreatic stump management, the mean differential cost and Quality-Adjusted Life Years (QALY) were calculated and plotted on a cost-utility plane.ResultsThe study population consisted of 564 patients. Among these, 271 (49%) patients were submitted to LDP, while 293 (51%) patients to RDP. After propensity score matching, the study population was composed of 159 patients in each group, with a median follow-up of 59 months. As regards the QoL analysis, global health and emotional functioning domains showed better results in the RDP group (p = 0.037 and p = 0.026, respectively), whereas the other did not differ. As expected, the median crude costs analysis confirmed that RDP was more expensive than LDP (16,041 Euros vs. 10,335 Euros, p < 0.001). However, the robotic approach had a higher probability of being more cost-effective than the laparoscopic procedure when a willingness to pay more than 5697 Euros/QALY was accepted.ConclusionRDP was associated with better QoL as explored by specific domains. Crude costs were higher for RDP, and the cost-effectiveness threshold was set at 5697 euros/QALY.

Greater Postoperative Biceps Tendon Migration Following Biceps Tenodesis Correlates with Lower Patient Reported Outcomes Scores

To assess the relationship between tendon migration, as measured by radiostereometric analysis (RSA), and patient-reported outcome measures (PROMs) following biceps tenodesis (BT); to determine the likelihood of achieving clinically significant outcomes (CSOs) following BT; and to identify factors that impact CSO achievement. Patients undergoing arthroscopic suprapectoral or open subpectoral BT at a single, high-volume academic medical center were prospectively enrolled. A tantalum bead sutured to the tenodesis construct was utilized as a radio-opaque marker. Biceps tendon migration was measured on calibrated radiographs at 12 weeks postoperatively. PROMs (Constant-Murley score [Constant], Single Assessment Numeric Evaluation [SANE], and Patient-Reported Outcomes Measurement Information Systemic-Upper Extremity [PROMIS-UE]) were collected preoperatively and at ≥2 years follow-up. Of 115 patients enrolled, 94 (82%) patients were included (median age=52 years and BMI=31.4 kg/m2). At a mean follow-up of 2.9 years, median Constant, SANE, and PROMIS-UE were 33 (interquartile range [IQR]=26-35), 90 (IQR=80-99), and 47 (IQR=42-58), respectively. Median tantalum bead migration was 6.5 mm (IQR 1.8-13.8). There was a significant correlation between migration and Constant (r2 = 0.222, beta= -0.554, 95% CI -1.027- [-0.081], P=0.022), SANE (r2 = 0.238, beta= -0.198, 95% CI -0.337 - [-0.058], P=0.006) and PROMIS-UE (r2 = 0.233, beta= -0.406, 95% CI -0.707 - [-0.104], P=0.009). In univariable analysis, higher BMI was associated with achievement of substantial clinical benefit (SCB, unadj-OR=1.078, 95%CI 1.007-1.161, P=0.038). Greater bead migration was negatively associated with achievement of minimal clinically important difference (MCID, unadj-OR=0.969, 95% CI 0.943-0.993, P=0.014) and patient acceptable symptomatic state (PASS, unadj-OR 0.965, 95% CI 0.937-0.989, P=0.008) on all 3 instruments. A 1 cm-increase in tenodesed biceps tendon migration was associated with a decrease in Constant, SANE, and PROMIS-UE of 6, 2, and 4 points, respectively, at a mean of 2.9 years after surgery. Most patients achieved clinically significant outcomes (CSOs) for these PROMs by latest follow-up, and greater biceps tendon construct migration was negatively associated with the likelihood of CSO achievement.

Trends in adoption of extravascular cardiac implantable electronic devices: the Dutch cohort.

Conventional implantable cardioverter-defibrillators (ICDs) and pacemakers carry arisk of pocket- and lead-related complications in particular. To avoid these complications, extravascular devices (EVDs) have been developed, such as the subcutaneous ICD (S-ICD) and leadless pacemaker (LP). However, data on patient or centre characteristics related to the actual adoption of EVDs are lacking. To assess real-world nationwide trends in EVD adoption in the Netherlands. Using the Netherlands Heart Registration, all consecutive patients with ade novo S‑ICD or conventional single-chamber ICD implantation between 2012-2020, or de novo LP or conventional single-chamber pacemaker implantation between 2014-2020 were included. Trends in adoption are described for various patient and centre characteristics. From 2012-2020, 2190 S‑ICDs and 10,683 conventional ICDs were implanted; from 2014-2020, 712 LPs and 11,103 conventional pacemakers were implanted. The general use has increased (S-ICDs 8 to 21%; LPs 1 to 8%), but this increase seems to have reached aplateau. S‑ICD recipients were younger than conventional ICD recipients (p < 0.001) and more often female (p < 0.001); LP recipients were younger than conventional pacemaker recipients (p < 0.001) and more often male (p = 0.03). Both S‑ICDs and LPs were mainly implanted in high-volume centres with cardiothoracic surgery on-site, although over time S‑ICDs were increasingly implanted in centres without cardiothoracic surgery (p < 0.001). This nationwide study demonstrated arelatively quick adoption of innovative EVDs with aplateau after approximately 4years. S‑ICD use is especially high in younger patients. EVDs are mainly implanted in high-volume centres with cardiothoracic surgery back-up, but S‑ICD use is expanding beyond those centres.

Extent of macroscopic vascular invasion predicts distant metastasis in primary leiomyosarcoma of the inferior vena cava.

In retroperitoneal leiomyosarcoma (RP LMS), the predominant issue is distant metastasis (DM). We sought to determine variables associated with this outcome and disease-specific death (DSD). Data were retrospectively collected on patients with primary RP LMS treated at a high-volume center from 2002 to 2023. For inferior vena cava (IVC)-origin tumors, the extent of macroscopic vascular invasion was re-assessed on each resection specimen and correlated with preoperative cross-sectional imaging. Crude cumulative incidences were estimated for DM and DSD and univariable and multivariable models were performed. Among 157 study patients, median tumor size was 11.0 cm and 96.2% of cases were intermediate or high grade. All patients underwent complete resection, 56.7% received chemotherapy (43.9% neoadjuvant) and 14.6% received radiation therapy. Only tumor size and grade and not site of tumor origin (e.g., IVC vs. other) were associated with DM and DSD (p < 0.05). Among 64 patients with IVC-origin tumors, a novel 3-tier classification was devised based on the level of intimal disruption, which was associated with both DM (p = 0.007) and DSD (0.002). In primary RP LMS, only tumor size and grade are predictive of DM and DSD. In IVC-origin tumors, the extent of macroscopic vascular invasion is also strongly predictive of these outcomes.

CodiReal-PT: National Survey on Current Practices in Right Colon Oncological Surgery

Abstract Introduction Colorectal cancer (CRC) is the third most prevalent tumor. Right colon cancer (RCC) comprises one-third of CRC cases and is associated with poorer outcomes, emphasizing the need for optimized treatment strategies. The present study aims to explore the nuances in the management of RCC across Portugal, focusing on surgical approaches and multidisciplinary treatment. Materials and Methods The CodiReal-PT was a cross-sectional survey-based study adhering to the guidelines of the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), focusing on current practices in RCC oncological surgery. The survey comprised 31 questions divided into 4 sections (demographics, multidisciplinary approach, surgery practices regarding RCC, and postoperative management). It was made available via e-mail to all active members of the Portuguese Society of Surgery (Sociedade Portuguesa de Cirurgia, SPCIR, in Portuguese), and data collection lasted from November to December 2022. Results Data from 69% of Portuguese public hospitals was obtained. All the participant hospitals had multidisciplinary team meetings to manage CRC cases. However, 17% (n = 6) did not discuss all elective-setting cases during their meetings. Dedicated colorectal surgical teams were present in 86% (n = 31) of hospitals. Furthermore, the presence of these dedicated teams was associated with better practices, namely a higher volume of right colectomies (mean: 51.8 ± 32.6 versus 23.8 ± 4.8; p = 0.001), a preference for the laparoscopic approach (93.5 versus 60.0%; p = 0.021), and standardization of anastomotic techniques (83.9 versus 40.0%; p = 0.029). Conclusion The present nationwide survey-based study provides a comprehensive landscape of RCC management practices across Portugal, underscoring the significant role of dedicated colorectal surgical teams and the need for further practice standardization. Nevertheless, multidisciplinary team meetings in all surveyed hospitals are an important indicator of improved RCC care. Future research should focus on the impact of specific surgical techniques on oncological outcomes and the potential benefits of centralizing care to high-volume centers.

Risk factors of textbook outcome in laparoscopic pancreatoduodenectomy: results from a prospective high-volume center study

ObjectiveAchieving textbook outcome (TO) implies a smooth recovery post-operation without specified composite complications. This study aimed to evaluate TO in laparoscopic pancreaticoduodenectomy (LPD) and identify independent risk factors associated with achieving TO.MethodsWe conducted a retrospective analysis of data from a randomized controlled trial on LPD at West China Hospital (ChiCTR1900026653). Patients were categorized into the TO and non-TO groups. Perioperative variables were compared between these groups. Multivariate logistic regression was utilized to identify the risk factors.ResultsA total of 200 consecutive patients undergoing LPD were included in this study. TO was achieved in 82.5% (n = 165) of the patients. Female patients (OR: 2.877, 95% CI: 1.219–6.790; P = 0.016) and those with a hard pancreatic texture (OR: 2.435, 95% CI: 1.018–5.827; P = 0.046) were associated with an increased likelihood of achieving TO.ConclusionsTO can be achieved in more than 80% of patients in a high-volume LPD center. Independent risk factors associated with achieving TO included gender (male) and pancreatic texture (soft).

Benchmark Outcomes for Distal Pancreatectomy: A Multicenter Prospective Snapshot Study from the Spanish Distal Pancreatectomy Project (SPANDISPAN).

Improving the quality of care is a priority for health systems to obtain better care and reduce costs. One of the tools for measuring quality is benchmarking (BM). We presented a 1-country prospective study of distal pancreatectomies (DPs) and determined BM. Prospective, multicenter, observational snapshot study of DP carried out at Spanish hepatopancreatobiliary centers for a year (February 1, 2022, to January 31, 2023). Hepatopancreatobiliary centers were defined as high volume if they performed more than 10 DPs per year. Inclusion criteria include any scheduled DP for any diagnosis and age older than 18 years. The low-risk group was defined following the criteria given by Durin and colleagues and major complications as Clavien-Dindo ≥III. A total of 313 patients from 42 centers and 46.6% from high-volume centers were included. Median DP by center was 7 (interquartile range 5 to 10), median age was 65 years (interquartile range 55 to 74), and 53.4% were female. The surgical approach was minimally invasive in 69.3%. Major complications were 21.1%. Postoperative pancreatic fistula grade B/C rate was 20.1%, and 90-day mortality was 1.6%. One hundred forty-three patients were in low-risk group (43.8%). Compared with previous BM data, an increasing MIS rate and fewer hospital stay were obtained. We present the first determination of DP-BM in a prospective series, obtaining similar results to the previous ones, but our BM values include a shorter hospital stay and a higher percentage of minimally invasive surgery probably related to Enhanced Recovery after Surgery protocols and prospective data collection. BM is a multiparameter valuable tool for reporting outcomes, comparing centers, and identifying the points to improve surgical care.

Comparison of Short-Term Outcomes after Robotic Surgery for Gastric Cancer in Elderly and Younger Patients: A Retrospective Cohort Study.

Robot-assisted surgery has recently been introduced to overcome some drawbacks and technical limitations in performing laparoscopic gastrectomy. The aim of the present study was to evaluate the feasibility and safety of robotic gastrectomy in elderly patients. The study enrolled 143 patients who underwent robotic gastrectomy in a single high-volume centre. All patients were divided into two groups based on age: elderly group ≥ 75 years old (EG; n = 64) and non-elderly group < 75 years old (NEG; n = 79). Comorbidities were significantly more frequent in the EG (95.3%) than in the NEG (81%) (p = 0.011). Similarly, the percentage of ASA 3 patients was significantly higher in the EG than in the NEG (43.8% vs. 24.0%, respectively; p = 0.048). Nevertheless, the incidence of Clavien-Dindo grade III and IV complications did not differ significantly between the two groups (10.9% in the EG and 6.3% in the NEG; p = 0.852). Moreover, operative time, re-operation rate, mean number of harvested lymph nodes, 30-day mortality, and median hospital stay were similar within the two groups. Our study suggests that robotic gastrectomy can be performed safely for elderly patients. In particular, chronological age does not seem to affect either the clinical or oncological short-term outcomes after robotic gastrectomy.
