Processing speed and its association with working memory and episodic memory 3-6 months after pediatric mild traumatic brain injury.

OBJECTIVE: Following mild traumatic brain injury (mTBI), children show reduced processing speed (PS). Evidence suggests that slowed PS after TBI is associated with working memory deficits. Our aim was to investigate several forms of PS and to examine its impact on working and episodic memory performance in children after mTBI. METHOD: We included data of 64 children after mTBI and 57 healthy control children aged 8-16 years. PS (Color Naming, Coding, Symbol Search, Alertness) was compared between groups 1 week (T1) and 3-6 months (T2) after the injury; working and episodic memory outcome was compared between groups at T2. RESULTS: Alertness at T1 and Color Naming at T1 and T2 were significantly reduced following mTBI compared to controls, although most group differences in PS disappeared when patients with previous impairments and mTBI were excluded. PS was predictive for episodic and working memory performance 3-6 months after injury, whereas group was a significant predictor of working memory. CONCLUSIONS: Compared to healthy controls, children after mTBI showed reduced performance in verbal PS, which was associated with working memory. In children who are symptomatic after mTBI, diagnostic screening of PS could be helpful in identifying patients that could profit from speed-improving strategies.

Non-anatomical liver resection for hepatocellular carcinoma: the SegSubTe classification to overcome the problem of heterogeneity.

BACKGROUND: The superiority of anatomical resection (AR) vs. non-anatomical resection (NAR) in the surgical management of hepatocellular carcinoma (HCC) is debated. ARs are well-defined procedures, whereas the lack of NAR standardization results in heterogeneous outcomes. This study aimed to introduce the SegSubTe classification for NAR detailing the appropriateness of the level of surgical section of the Glissonean pedicles feeding the tumor. METHODS: A single-center retrospective analysis of pre- and postoperative imaging of consecutive patients treated with NAR for single HCC between 2012 and 2020 was conducted. The quality of surgery was assessed classifying the type of vascular supply and the level of surgical section (segmental, subsegmental or terminal next to the tumor) of vascular pedicles feeding the HCCs; then, the population was divided in "SegSubTe-IN" or "SegSubTe-OUT" groups, and the tumor recurrence and survival were analyzed. RESULTS: Ninety-seven patients who underwent NAR were included; 76% were SegSubTe-IN and 24% were SegSubTe-OUT. Total disease recurrence, local recurrence and cut-edge recurrence in the SegSubTe-IN vs. SegSubTe-OUT groups were 50% vs. 83% (P = 0.006), 20% vs. 52% (P = 0.003) and 16% vs. 39% (P = 0.020), respectively. SegSubTe-OUT odds ratio for local recurrence was 4.1 at univariate regression analysis. One-, three-, and five-year disease-free survival rates in the SegSubTe-IN vs. SegSubTe-OUT groups were 81%, 58% and 35% vs. 46%, 21% and 11%, respectively (P < 0.001). CONCLUSIONS: The SegSubTe classification is a useful tool to stratify and standardize NAR for HCC, aiming at improving long-term oncological outcomes and reducing the heterogeneity of quality of NAR for HCC.

Dynamic surgical anatomy using 3D reconstruction technology in complex hepato-biliary surgery with vascular involvement. Results from an international multicentric survey.

INTRODUCTION: Three-dimensional liver modeling can lead to substantial changes in choosing the type and extension of liver resection. This study aimed to explore whether 3D reconstruction helps to better understand the relationship between liver tumors and neighboring vascular structures compared to standard 2D CT scan images. METHODS: Contrast-enhanced CT scan images of 11 patients suffering from primary and secondary hepatic tumors were selected. Twenty-three experienced HBP surgeons participated to the survey. A standardized questionnaire outlining 16 different vascular structures (items) having a potential relationship with the tumor was provided. Intraoperative and histopathological findings were used as the reference standard. The proper hypothesis was that 3D accuracy is greater than 2D. As a secondary endpoint, inter-raters' agreement was explored. RESULTS: The mean difference between 3D and 2D, was 2.6 points (SE: 0.40; 95 % CI: 1.7-3.5; p < 0.0001). After sensitivity analysis, the results favored 3D visualization as well (mean difference 1.7 points; SE: 0.32; 95 % CI: 1.0-2.5; p = 0.0004). The inter-raters' agreement was moderate for both methods (2D: W = 0.45; 3D: W = 0.44). CONCLUSION: 3D reconstruction may give a significant contribution to better understanding liver vascular anatomy and the precise relationship between the tumor and the neighboring structures.

The Effect of a Liver Transplant Program on the Outcomes of Resectable Hepatocellular Carcinoma: A Nationwide Multicenter Analysis.

OBJECTIVE: To evaluate the effect of a liver transplantation (LT) program on the outcomes of resectable hepatocellular carcinoma (HCC). BACKGROUND: Surgical treatment of HCC includes both hepatic resection (HR) and LT. However, the presence of cirrhosis and the possibility of recurrence make the management of this disease complex and probably different according to the presence of a LT program. METHODS: Patients undergoing HR for HCC between January 2005 and December 2019 were identified from a national database of HCC. The main study outcomes were major surgical complications according to the Comprehensive Complication Index, posthepatectomy liver failure (PHLF), 90-day mortality, overall survival, and disease-free survival. Secondary outcomes were salvage liver transplantation (SLT) and postrecurrence survival. RESULTS: A total of 3202 patients were included from 25 hospitals over the study period. Three of 25 (12%) had an LT program. The presence of an LT program within a center was associated with a reduced probability of PHLF (odds ratio=0.38) but not with overall survival and disease-free survival. There was an increased probability of SLT when HR was performed in a transplant hospital (odds ratio=12.05). Among transplant-eligible patients, those who underwent LT had a significantly longer postrecurrence survival. CONCLUSIONS: This study showed that the presence of a LT program was associated with decreased PHLF rates and an increased probability to receive SLT in case of recurrence.

Minor head trauma in infants - how accurate is cranial ultrasound performed by trained radiologists?

Correct management of infants after minor head trauma is crucial to minimize the risk to miss clinically important traumatic brain injury (ciTBI). Current practices typically involve CT or in-hospital surveillance. Cranial ultrasound (CUS) provides a radiation-free and fast alternative. This study examines the accuracy of radiologist-performed CUS to detect skull fracture (SF) and/or intracranial hemorrhage (ICH). An inconspicuous CUS followed by an uneventful clinical course would allow exclusion of ciTBI with a great certainty. This monocentric, retrospective, observational study analyzed CUS in infants (< 12 months) after minor head trauma at Bern University Children's Hospital, between 7/2013 and 8/2020. The primary outcome was the sensitivity and specificity of CUS in detecting SF and/or ICH by comparison to the clinical course and to additional neuroimaging. Out of a total of 325 patients, 73% (n = 241) had a normal CUS, 17% (n = 54) were found with SF, and ICH was diagnosed in 2.2% patients (n = 7). Two patients needed neurosurgery and three patients deteriorated clinically during surveillance. Additional imaging was performed in 35 patients. The sensitivity of CUS was 93% ([0.83, 0.97] 95% CI) and the specificity 98% ([0.95, 0.99] 95% CI). All false-negative cases originated in missed SF without clinical deterioration; no ICH was missed.  Conclusion: This study shows high accuracy of CUS in exclusion of SF and ICH, which can cause ciTBI. Therefore, CUS offers a reliable method of neuroimaging in infants after minor head trauma and gives reassurance to reduce the duration of in-hospital surveillance. What is Known: • Minor head trauma can cause clinically important traumatic brain injury in infants, and the management of these cases is a challenge for the treating physician. • Cranial ultrasound (CUS) is regularly used in neonatology, but its accuracy after head trauma in infants is controversial. What is New: • CUS performed by a trained radiologist can exclude findings related to clinically important traumatic brain injury (ciTBI) with high sensitivity and specificity. It therefore offers reassurance in the management of infants after minor head trauma.

Survival benefit of second line therapies for recurrent hepatocellular carcinoma: repeated hepatectomy, thermoablation and second-line transplant referral in a real life national scenario.

BACKGROUND: Despite second-line transplant(SLT) for recurrent hepatocellular carcinoma(rHCC) leads to the longest survival after recurrence(SAR), its real applicability has never been reported. The aim was to compare the SAR of SLT versus repeated hepatectomy and thermoablation(CUR group). METHODS: Patients were enrolled from the Italian register HE.RC.O.LE.S. between 2008 and 2021. Two groups were created: CUR versus SLT. A propensity score matching (PSM) was run to balance the groups. RESULTS: 743 patients were enrolled, CUR = 611 and SLT = 132. Median age at recurrence was 71(IQR 6575) years old and 60(IQR 53-64, p < 0.001) for CUR and SLT respectively. After PSM, median SAR for CUR was 43 months(95%CI = 37 - 93) and not reached for SLT(p < 0.001). SLT patients gained a survival benefit of 9.4 months if compared with CUR. MilanCriteria(MC)-In patients were 82.7% of the CUR group. SLT(HR 0.386, 95%CI = 0.23 - 0.63, p < 0.001) and the MELD score(HR 1.169, 95%CI = 1.07 - 1.27, p < 0.001) were the only predictors of mortality. In case of MC-Out, the only predictor of mortality was the number of nodules at recurrence(HR 1.45, 95%CI= 1.09 - 1.93, p = 0.011). CONCLUSION: It emerged an important transplant under referral in favour of repeated hepatectomy or thermoablation. In patients with MC-Out relapse, the benefit of SLT over CUR was not observed.

Hepatectomy Versus Sorafenib in Advanced Nonmetastatic Hepatocellular Carcinoma: A Real-life Multicentric Weighted Comparison.

OBJECTIVE: The aim of the study was to compare SURG vs SOR regarding the OS and progression-free survival (PFS) in a real-world clinical scenario. BACKGROUND DATA: The treatment for advanced nonmetastatic HCC belonging to the Barcelona Clinic Liver Cancer stage C (BCLC C) is still controversial. METHODS: BCLC C patients without extrahepatic spread and tumoral invasion of the main portal trunk were considered. Surgical patients were obtained from the HE.RC.O.LE.S. Register, whereas sorafenib patients were obtained from the ITA.LI.CA register The inverse probability weighting (IPW) method was adopted to balance the confounders between the 2 groups. RESULTS: Between 2008 and 2019, 478 patients were enrolled: 303 in SURG and 175 in SOR group. Eastern Cooperative Oncological Group Performance Status (ECOG-PS), presence of cirrhosis, steatosis, Child-Pugh grade, hepatitis B virus and hepatitis C virus, alcohol intake, collateral veins, bilobar disease, localization of the tumor thrombus, number of nodules, alpha-fetoprotein, age, and Charlson Comorbidity index were weighted by IPW to create two balanced pseudo-populations: SURG = 374 and SOR = 263. After IPW, 1-3-5 years OS was 83.6%, 68.1%, 55.9% for SURG, and 42.3%, 17.8%, 12.8% for SOR (P < 0.001). Similar trends were observed after subgrouping patients by ECOG-PS = 0 and ECOG-PS >0, and by the intrahepatic location of portal vein invasion. At Cox regression, sorafenib treatment (hazard ratio 4.436; 95% confidence interval 3.19-6.15; P < 0.001) and Charlson Index (hazard ratio 1.162; 95% confidence interval 1.06-1.27; P = 0.010) were the only independent predictors of mortality. PFS at 1-3-5 years were 65.9%, 40.3%, 24.3% for SURG and 21.6%, 3.5%, 2.9% for SOR (P = 0.007). CONCLUSIONS: In BCLC C patients without extrahepatic spread but with intrahepatic portal invasion, liver resection, if feasible, was followed by better OS and PFS compared with sorafenib.

Consensus Minimal Dataset for Pediatric Emergency Medicine in Switzerland.

OBJECTIVES: Standardized, harmonized data sets generated through routine clinical and administrative documentation can greatly accelerate the generation of evidence to improve patient care. The objective of this study was to define a pediatric emergency medicine (PEM) minimal dataset for Switzerland (Swiss PEM minimal dataset) and to contribute a subspecialty module to a national pediatric data harmonization process (SwissPedData). METHODS: We completed a modified Delphi survey, inviting experts from all major Swiss pediatric emergency departments (PEDs). RESULTS: Twelve experts from 10 Swiss PEDs, through 3 Delphi survey rounds and a moderated e-mail discussion, suggested a subspecialty module for PEM to complement the newly developed SwissPedData main common data model (CDM). The PEM subspecialty CDM contains 28 common data elements (CDEs) specific to PEM. Additional CDEs cover PEM-specific admission processes (type of arrival), timestamps (time of death), greater details on investigations and treatments received at the PED, and PEM procedures (eg, procedural sedation). In addition to the 28 CDEs specific to PEM, 43 items from the SwissPedData main CDM were selected to create a Swiss PEM minimal dataset. The final Swiss PEM minimal dataset was similar in scope and content to the registry of the Pediatric Emergency Care Applied Research Network. CONCLUSIONS: A practical minimal dataset for PEM in Switzerland was developed through recognized consensus methodology. The Swiss PEM minimal dataset developed by Swiss PEM experts will facilitate international data sharing for PEM research and quality improvement projects.

The largest western experience on salvage hepatectomy for recurrent hepatocellular carcinoma: propensity score-matched analysis on behalf of He.RC.O.Le.Study Group.

BACKGROUND: We aimed to evaluate, in a large Western cohort, perioperative and long-term oncological outcomes of salvage hepatectomy (SH) for recurrent hepatocellular carcinoma (rHCC) after primary hepatectomy (PH) or locoregional treatments. METHODS: Data were collected from the Hepatocarcinoma Recurrence on the Liver Study Group (He.RC.O.Le.S.) Italian Registry. After 1:1 propensity score-matched analysis (PSM), two groups were compared: the PH group (patients submitted to resection for a first HCC) and the SH group (patients resected for intrahepatic rHCC after previous HCC-related treatments). RESULTS: 2689 patients were enrolled. PH included 2339 patients, SH 350. After PSM, 263 patients were selected in each group with major resected nodule median size, intraoperative blood loss and minimally invasive approach significantly lower in the SH group. Long-term outcomes were compared, with no difference in OS and DFS. Univariate and multivariate analyses revealed only microvascular invasion as an independent prognostic factor for OS. CONCLUSION: SH proved to be equivalent to PH in terms of safety, feasibility and long-term outcomes, consistent with data gathered from East Asia. In the awaiting of reliable treatment-allocating algorithms for rHCC, SH appears to be a suitable alternative in patients fit for surgery, regardless of the previous therapeutic modality implemented.

Benchmarking postoperative outcomes after open liver surgery for cirrhotic patients with hepatocellular carcinoma in a national cohort.

BACKGROUND: Benchmark analysis for open liver surgery for cirrhotic patients with hepatocellular carcinoma (HCC) is still undefined. METHODS: Patients were identified from the Italian national registry HE.RC.O.LE.S. The Achievable Benchmark of Care (ABC) method was employed to identify the benchmarks. The outcomes assessed were the rate of complications, major comorbidities, post-operative ascites (POA), post-hepatectomy liver failure (PHLF), 90-day mortality. Benchmarking was stratified for surgical complexity (CP1, CP2 and CP3). RESULTS: A total of 978 of 2698 patients fulfilled the inclusion criteria. 431 (44.1%) patients were treated with CP1 procedures, 239 (24.4%) with CP2 and 308 (31.5%) with CP3 procedures. Patients submitted to CP1 had a worse underlying liver function, while the tumor burden was more severe in CP3 cases. The ABC for complications (13.1%, 19.2% and 28.1% for CP1, CP2 and CP3 respectively), major complications (7.6%, 11.1%, 12.5%) and 90-day mortality (0%, 3.3%, 3.6%) increased with the surgical difficulty, but not POA (4.4%, 3.3% and 2.6% respectively) and PHLF (0% for all groups). CONCLUSION: We propose benchmarks for open liver resections in HCC cirrhotic patients, stratified for surgical complexity. The difference between the benchmark values and the results obtained during everyday practice reflects the room for potential growth, with the aim to encourage constant improvement among liver surgeons.

Effect of Diameter and Number of Hepatocellular Carcinomas on Survival After Resection, Transarterial Chemoembolization, and Ablation.

INTRODUCTION: Most studies predicting survival after resection, transarterial chemoembolization (TACE), and ablation analyzed diameter and number of hepatocellular carcinomas (HCCs) as dichotomous variables, resulting in an underestimation of risk variation. We aimed to develop and validate a new prognostic model for patients with HCC using largest diameter and number of HCCs as continuous variables. METHODS: The prognostic model was developed using data from patients undergoing resection, TACE, and ablation in 645 Japanese institutions. The model results were shown after balanced using the inverse probability of treatment-weighted analysis and were externally validated in an international multi-institution cohort. RESULTS: Of 77,268 patients, 43,904 patients, including 15,313 (34.9%) undergoing liver resection, 13,375 (30.5%) undergoing TACE, and 15,216 (34.7%) undergoing ablation, met the inclusion criteria. Our model (http://www.u-tokyo-hbp-transplant-surgery.jp/about/calculation.html) showed that the 5-year overall survival (OS) in patients with HCC undergoing these procedures decreased with progressive incremental increases in diameter and number of HCCs. For patients undergoing resection, the inverse probability of treatment-weighted-adjusted 5-year OS probabilities were 10%-20% higher compared with patients undergoing TACE for 1-6 HCC lesions <10 cm and were also 10%-20% higher compared with patients undergoing ablation when the HCC diameter was 2-3 cm. For patients undergoing resection and TACE, the model performed well in the external cohort. DISCUSSION: Our novel prognostic model performed well in predicting OS after resection and TACE for HCC and demonstrated that resection may have a survival benefit over TACE and ablation based on the diameter and number of HCCs.

Curative versus palliative treatments for recurrent hepatocellular carcinoma: a multicentric weighted comparison.

BACKGROUND: Management of recurrence after surgery for hepatocellular carcinoma (rHCC) is still a debate. The aim was to compare the Survival after Recurrence (SAR) of curative (surgery or thermoablation) versus palliative (TACE or Sorafenib) treatments for patients with rHCC. METHODS: This is a multicentric Italian study, which collected data between 2007 and 2018 from 16 centers. Selected patients were then divided according to treatment allocation in Curative (CUR) or Palliative (PAL) Group. Inverse Probability Weighting (IPW) was used to weight the groups. RESULTS: 1,560 patients were evaluated, of which 421 experienced recurrence and were then eligible: 156 in CUR group and 256 in PAL group. Tumor burden and liver function were weighted by IPW, and two pseudo-population were obtained (CUR = 397.5 and PAL = 415.38). SAR rates at 1, 3 and 5 years were respectively 98.3%, 76.7%, 63.8% for CUR and 91.7%, 64.2% and 48.9% for PAL (p = 0.007). Median DFS was 43 months (95%CI = 32-74) for CUR group, while it was 23 months (95%CI = 18-27) for PAL (p = 0.017). Being treated by palliative approach (HR = 1.75; 95%CI = 1.14-2.67; p = 0.01) and having a median size of the recurrent nodule>5 cm (HR = 1.875; 95%CI = 1.22-2.86; p = 0.004) were the only predictors of mortality after recurrence, while time to recurrence was the only protective factor (HR = 0.616; 95%CI = 0.54-0.69; p<0.001). CONCLUSION: Curative approaches may guarantee long-term survival in case of recurrence.

The Impact of Hospital Volume on Failure to Rescue after Liver Resection for Hepatocellular Carcinoma: Analysis from the HE.RC.O.LE.S. Italian Registry.

OBJECTIVE: The aim of this study was to evaluate correlation between centers' volume and incidence of failure to rescue (FTR) following liver resection for hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: FTR, defined as the probability of postoperative death among patients with major complication, has been proposed to assess quality of care during hospitalization. Perioperative management is challenging in cirrhotic patients and the ability to recognize and treat a complication may be fundamental to rescue patients from the risk of death. METHODS: Patients undergoing liver resection for HCC between 2008 and 2018 in 18 Centers enrolled in the He.Rc.O.Le.S. Italian register. Early results included major complications (Clavien ≥3), 90-day mortality, and FTR and were analyzed according to center's volume. RESULTS: Among 1935 included patients, major complication rate was 9.4% (8.6%, 12.3%, and 7.0% for low-, intermediate- and high-volume centers, respectively, P = 0.001). Ninety-day mortality rate was 2.6% (3.7%, 4.2% and 0.9% for low-, intermediate- and high-volume centers, respectively, P < 0.001). FTR was significantly higher at low- and intermediate-volume centers (28.6% and 26.5%, respectively) than at high-volume centers (6.1%, P = 0.002). Independent predictors for major complications were American Society of Anesthesiologists (ASA) >2, portal hypertension, intraoperative blood transfusions, and center's volume. Independent predictors for 90-day mortality were ASA >2, Child-Pugh score B, BCLC stage B-C, and center's volume. Center's volume and BCLC stage were strongly associated with FTR. CONCLUSIONS: Risk of major complications and mortality was related with comorbidities, cirrhosis severity, and complexity of surgery. These factors were not correlated with FTR. Center's volume was the only independent predictor related with severe complications, mortality, and FTR.

Treatment of hepatocellular carcinoma beyond the Milan criteria. A weighted comparative study of surgical resection versus chemoembolization.

BACKGROUND: Optimal treatment of hepatocellular carcinoma (HCC) beyond the Milan criteria (MC) is debated. The aim of the study was to assess overall-survival (OS) and disease-free-survival (DFS) for HCC beyond MC when treated by trans-arterial-chemoembolization (TACE) or surgical resection (SR). METHOD: between 2005 and 2015, all patients with a first diagnosis of HCC beyond MC(1 nodule>5 cm, or 3 nodules>3 cm without macrovascular invasion) were evaluated. Analyses were carried out through Kaplan-Meier, Cox models and the inverse probability weighting (IPW) method to reduce allocation bias. Sub-analyses have been performed for multinodular and single large tumors compared with a MC-IN cohort. RESULTS: 226 consecutive patients were evaluated: 118 in SR group and 108 in TACE group. After IPW, the two pseudo-populations were comparable for tumor burden and liver function. In the SR group, 1-5 years OS rates were 72.3% and 35% respectively and 92.7% and 39.3% for TACE (p = 0.500). The median DFS was 8 months (95%CI:8-9) for TACE, and 11 months (95%CI:9-12) for SR (p < 0.001). TACE was an independent predictor for recurrence (HR 1.5; 95%CI: 1.1-2.1; p = 0.015). Solitary tumors > 5 cm and multinodular disease had comparable OS and DFS as Milan-IN group (p > 0.05). CONCLUSION: Surgery allowed a better control than TACE in patient bearing HCC beyond MC. This translated into a significant benefit in terms of DFS but not OS.

The impact of age and ageing on hepatocarcinoma surgery: Short- and long-term outcomes in a multicentre propensity-matched cohort.

BACKGROUND: Management of malignancy in elderly patients is challenging. We aimed to assess the impact of age and ageing on overall survival (OS), recurrence-free survival (RFS), tumour-specific survival (TSS) and potential years of life lost (PYLL) after surgery for hepatocarcinoma (HCC). METHODS: Consecutive patients treated for HCC between 2005 and 2015 were evaluated. Patients were divided according to age-decade. Afterwards, elderly patients (≥75 years) were compared with patients < 75 years. A 1:1 propensity matching was used to reduce the risk of bias. Survival was estimated by Kaplan-Meier method and Cox regression analysis. RESULTS: Four hundred and thirty-nine patients were stratified: group 1 (age ≤ 55, n = 72), group 2 (age: 56-65, n = 133), group 3 (age: 66-74, n = 141) and group 4 (age ≥ 75, n = 93). Group 1 had the highest median PYLL (27.6, IQR 24.6-32.5) while group 4 the lowest (2.0, IQR 0-9.6; P < 0.001). Comparing elderly vs younger, there were no significant differences in terms of OS (P = 0.054), TSS (P = 0.321) and RFS (P = 0.240). Ageing was the only variable associated with post-operative complications (OR: 2.51; 95% CI: 1.23-5.13; P = 0.025) and liver-related morbidity was an independent predictor of OS. (HR 2.49, 95% CI: 1.34-4.64, P = 0.004). CONCLUSION: Ageing per se is not an absolute contraindication for liver resection, given the acceptable oncologic long-term prognosis, but the worse short-term outcomes in the elderly should induce an accurate patient selection.

Recurrence Patterns After Anatomic or Parenchyma-Sparing Liver Resection for Hepatocarcinoma in a Western Population of Cirrhotic Patients.

BACKGROUND: The optimal surgical strategy to lessen the risk of hepatocarcinoma (HCC) recurrence is debated. This study aimed to investigate the role of anatomic resection (AR) and parenchyma-sparing resection (PSR) in HCC recurrence patterns. METHODS: The study analyzed 384 cirrhotic patients with a first diagnosis of HCC. Of these patients, 142 underwent AR, and 242 underwent PSR. The two groups were unbalanced at the univariate analysis. To minimize this bias, a 1:1 propensity score-matching analysis (PSA) was used. Disease-free survival (DFS) curves were analyzed by the Kaplan-Maier method. RESULTS: The PSA allowed pairing of 200 patients (100 for AR and 100 for PSR). In this study, 59 patients (62.8%) had recurrence after AR compared with 58 patients (63.7%) after PSR (p = 0.891). The rates of local recurrence were respectively 15.3% and 15.5% (p = 0.968). When microvascular invasion was considered, the median DFS was 10.7 months for AR and 9.4 months for PSR (p = 0.607). In comparisons of AR and PSR, DFS did not differ significantly between subgroups with high histologic grading (p = 0.520), multiple nodules (p = 0.307), and Child-Pugh B (p = 0.679). CONCLUSION: Excision of the anatomic segment did not seem to reduce the rate of relapse or recurrence patterns significantly, even in high-risk subgroups.

Does the Pringle maneuver affect survival and recurrence following surgical resection for hepatocellular carcinoma? A western series of 441 patients.

BACKGROUND: The impact of the Pringle maneuver (PM) on long-term outcome after curative resection for hepatocellular carcinoma (HCC) is controversial, with eastern series reporting conflicting results. We aim to evaluate the impact of the PM in a western cohort. METHODS: We retrospectively analyzed patients with HCC who underwent liver resection between January 2001 and August 2015. Patients were divided in two groups based the use of the PM during resection. Primary outcomes were overall survival (OS) and disease-free survival (DFS). RESULTS: A total of 441 patients were analyzed. Of these, 176 patients (39.9%) underwent PM. Median OS was 46.4 months (95%CI: 34.1-58.7) for the PM group and 56.5 months (95%CI: 37.1-75.9) for the no-PM group (P = 0.188), with a median DFS of 26.7 months (95%CI: 15.7-37.7) and 24.9 months (95%CI: 18.1-31.7), respectively (P = 0.883). CONCLUSIONS: These results suggest that PM does not increase the risk of tumor recurrence or decrease long-term survival.

Surgical management of duodenal stump fistula after elective gastrectomy for malignancy: an Italian retrospective multicenter study.

BACKGROUND: Duodenal stump fistula (DSF) is a severe complication of gastrectomy. Although nonsurgical therapy is preferred, surgery is still mandatory in one third of DSF patients. The aim of this article is to analyze the surgical management of DSF and factors related to its outcome. METHODS: We performed a retrospective multicenter study using data from January 1990 to November 2011 in 16 Italian surgery centers. We collected 8,268 elective gastrectomies for malignancies, 7,987 by the laparotomic and 281 by the laparoscopic approach. Two hundred five patients developed a DSF, 75 of whom underwent surgery for DSF. We analyzed mortality and DSF healing time as well as the impact of clinical, oncological, and surgical characteristics. RESULTS: The laparoscopic approach increased the risk of DSF development (odds ratio 5.6, 95% confidence interval 2.7-10.6, P < 0.001). The indication for first DSF surgery was intra-abdominal sepsis; the failure rate was over 30%, associated with the appearance of fistulas of neighboring organs, bleeding, and the need for reoperations. The mortality rate was 28% and was related to the presence of vascular disease (P = 0.04), more than one reoperation (P = 0.05), sepsis (P < 0.001), and renal failure (P < 0.001). Fifty-four patients recovered after a median of 39 days (interquartile range 22-68 days); the need to perform more reoperations (P < 0.01) and the presence of an abdominal abscess (P < 0.01) led to an increase in healing time. CONCLUSIONS: Surgery for DSF has a poor prognosis. Our data will help to identify patients at risk of death, but unfortunately could not establish the best surgical procedure applicable to all cases of DSF.

Robotic Surgery in Patients With Locally Advanced Cervical Cancer After Neoadjuvant Chemotherapy: Survival Outcomes.

AIM: To evaluate the survival outcomes of consecutive patients with locally advanced cervical cancer (LACC) who underwent comprehensive robotic surgery after neoadjuvant chemotherapy (NACT). MATERIALS AND METHODS: Since 2009, patients with LACC (FIGO [International Federation of Gynecology and Obstetrics] stages IB2-IIB) were submitted to robotic surgical staging after 3 cycles of NACT. Clinical objective tumor response was assessed according to the Response Evaluation Criteria in Solid Tumors, whereas pathologic responses were defined according to the criteria of the European study SNAP01. Univariable and multivariable analyses were performed to assess potential clinicopathologic prognostic factors affecting progression-free survival and overall survival (OS). RESULTS: During the study period, 32 patients meeting the inclusion criteria were managed. The median (range) age and body mass index were 47.3 (8.6-75.5) years and 22.7 (17.5-37.1) kg/m(2), respectively. Overall, 28.0 (range, 12-58) lymph nodes were retrieved. According to the final pathologic examination, 6 (18.8%) women had positive pelvic lymph nodes, whereas 16 (50.0%) patients achieved an optimal pathological response. After a median follow-up of 36.3 (range, 5.2-71.1) months, 6 (18.8%) patients had a recurrence and subsequently died of disease.Positive nodal status was the only independent predictor of both progression-free survival (12.5 [2.3-69.1]; P < 0.0001) and OS (12.0 [2.0-60.4]; P < 0.0001) at multivariable analysis. CONCLUSIONS: Nodal status represents the strongest predictor of survival in women with LACC. Similarly, NACT including 3 agents (TIP [paclitaxel 175 mg/m(2) + ifosfamide 5 g/m(2) + cisplatin 75 mg/m(2)] and TEP [paclitaxel 175 mg/m(2) + epirubicin 80 mg/m(2) + cisplatin 75 mg/m(2)] regimens) warranted better OS than those achieved by other schedules.
