Abstract
INTRODUCTION Surgical stress results in immune dysfunction, predisposing patients to infections in the postoperative period and potentially increasing the risk of cancer recurrence. Perioperative immunonutrition with arginine-enhanced diets has been found to potentially improve short-term and cancer outcomes. This study seeks to measure the impact of perioperative immunomodulation on biomarkers of the immune response and perioperative outcomes following hepatopancreaticobiliary surgery. METHODS AND ANALYSIS This is a 1:1:1 randomised, controlled and blinded superiority trial of 45 patients. Baseline and perioperative variables were collected to evaluate immune function, clinical outcomes and feasibility outcomes. The primary outcome is a reduction in natural killer cell killing as measured on postoperative day 1 compared with baseline between the control and experimental cohorts. ETHICS AND DISSEMINATION This trial has been approved by the research ethics boards at participating sites and Health Canada (parent control number: 223646). Results will be distributed widely through local and international meetings, presentation, publication and ClinicalTrials.gov (identifier: NCT04549662). Any modifications to the protocol will be communicated via publications and ClinicalTrials.gov. TRIAL REGISTRATION NUMBER ClinicalTrials.gov identifier: NCT04549662.

Abstract
BACKGROUND Liver surgery remains a cornerstone of potentially curative multimodal treatments for primary malignancies of the liver and hepatic metastases. Improving perioperative safety is a prerequisite in this context. Perioperative blood transfusions negatively influence postoperative recovery. This study aimed to identify risk factors for perioperative packed red blood cell (PRBC) transfusion and to elucidate its effect on postoperative outcomes. METHODS This was an observational study of a prospective data collection. A monocentric, retrospective analysis of 1118 hepatectomies at the University Hospital Carl Gustav Carus between 2013 and 2020 was conducted to compare postoperative short- and long-term outcomes in patients undergoing curative intended liver resection of hepatic primary or secondary malignancies. The outcomes were compared between 356 patients (31.8%) who received PRBC transfusions during surgery or within 7 days after surgery and 762 patients (68.2%) who did not receive PRBC transfusions. RESULTS Preoperative anemia could be observed in 45.0% of the whole cohort: 65.7% in the PRBC transfusion group and 35.3% in the nontransfused group. Postoperative complications were significantly more common in the PRBC transfusion group in association with prolonged lengths of hospital stay and increased 30-day mortality than in the nontransfused group. After adjustment for possible confounders, preexisting kidney failure, preoperative hemoglobin and albumin levels outside of the reference range, intraoperative plasma transfusions, and overall surgery time were recognized as negative predictors for perioperative PRBC transfusions. PRBC transfusion increased the risk of death by approximately 38.8% (hazard ratio, 1.388; 95% CI, 1.027-1.876; P = .033), whereas no influence on recurrence-free survival (RFS) was observed. CONCLUSION PRBC transfusions were associated with postoperative morbidity and mortality after curative-intended surgery for liver cancers and represented an independent poor prognostic indicator for overall survival but not for RFS.

Abstract
INTRODUCTION Liver disease causes 2 million deaths annually, accounting for 4% of all deaths worldwide. Liver surgery is one of the effective therapeutic options. Bleeding is a major complication during liver surgery. Perioperative bleeding and allogeneic blood transfusion may deteriorate the prognosis. Terlipressin (TP), a synthetic analogue of the antidiuretic hormone, may reduceblood loss during abdominal surgery. Several clinical centres have attempted to use TP during liver surgery, but the evidence for its effectiveness in reducing blood loss and the need for allogeneic blood transfusion, as well as its safety during the perioperative period, remains unclear. The aim of this systematic review and meta-analysis is to evaluate the efficacy and safety of TP in reducing blood loss and allogeneic blood transfusion needs during liver surgery. METHODS AND ANALYSIS We will search PubMed, EMBASE, the Cochrane Library and Web of Science for studies on perioperative use of TP during liver surgery from inception to July 2023. We will limit the language to English, and two reviewers will independently screen and select articles. The primary study outcomes are estimated blood loss and the need for allogeneic blood transfusion. Secondary outcomes include operating time, intensive care unit stay, length of stay, intraoperative urine output, acute kidney injury rate, postoperative complications, hepatic and renal function during follow-up, and TP-related adverse effects. We will include studies that met the following criteria: (1) randomised controlled trials (RCTs), cohort studies or case-control studies; (2) the publication time was till July 2023; (3) adult patients (≥18 years old) undergoing elective liver surgery; (4) comparison of TP with other treatments and (5) the study includes at least one outcome. We will exclude animal studies, case reports, case series, non-original articles, reviews, paediatric articles, non-controlled trials, unpublished articles, non-English articles and other studies that are duplicates. We will use Review Manager V.5.3 software for meta-analysis and perform stratification analysis for the study quality of RCTs based on the Jadad score. For cohort or case-control studies, the study quality will be analysed based on Newcastle-Ottawa Scale scores. Grading of Recommendations, Assessment, Development and Evaluation will be used to assess confidence in the cumulative evidence. For primary outcomes, we will conduct subgroup analyses based on meta-regression. We will also perform leave-one-out sensitivity analyses to evaluate the effect of each individual study on the combined results by removing the individual studies one by one for outcomes with significant heterogeneity. The protocol follows the Cochrane Handbook for Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines. ETHICS AND DISSEMINATION This study is a secondary analysis of existing data; therefore, it does not require ethical approval. We will disseminate the results through peer-reviewed publications.

Abstract
BACKGROUND The risk of venous thromboembolism (VTE) after hepatopancreatobiliary (HPB) surgery is high. Extended postdischarge prophylaxis in this patient population has been controversial. This study aimed to examine the safety of postdischarge extended VTE prophylaxis in patients at high risk of VTE events after HPB surgery. METHODS Adult patients risk stratified as very high risk of VTE who underwent HPB operations between 2014 and 2020 at a quaternary care center were included. Patients were matched 1:2 extended VTE prophylaxis to the control group (patients who did not receive extended prophylaxis). Analyses compared the proportions of adverse bleeding events between groups. RESULTS A total of 307 patients were included: 103 in the extended prophylaxis group and 204 in the matched control group. Demographics were similar between groups. More patients in the extended VTE prophylaxis group had a history of VTE (9% vs 3%; P = .045). There was no difference in bleeding events between the extended VTE prophylaxis and the control group (6% vs 2%; P = .091). Of the 6 patients with bleeding events in the VTE prophylaxis group, 5 had gastrointestinal (GI) bleeding, and 1 had hemarthrosis. Of the 4 patients with bleeding events in the control group, 1 had intra-abdominal bleeding, 2 had GI bleeding, and 1 had intra-abdominal and GI bleeding. CONCLUSION Patients discharged with extended VTE prophylaxis after HPB surgery did not experience more adverse bleeding events compared with a matched control group. Routine postdischarge extended VTE prophylaxis is safe in patients at high risk of postoperative VTE after HPB surgery.

Abstract
BACKGROUND While risk-stratified post-hepatectomy pathways (RSPHPs) reduce length-of-stay, can they stratify hepatectomy patients by risk of early postoperative events. METHODS 90-day outcomes from consecutive hepatectomies were analyzed (1/1/2017-12/31/2021). Pre/post-pathway analysis was performed for pathways: minimally invasive surgery ("MIS"); non-anatomic resection/left hepatectomy ("low-intermediate risk"); right/extended hepatectomy ("high-risk"); "Combination" operations. Time-to-event (TTE) analyses for readmission and interventional radiology procedures (IRPs) was performed. RESULTS 1354 patients were included: MIS/n= 119 (9 %); low-intermediate risk/n= 443 (33 %); high-risk/n= 328 (24 %); Combination/n= 464 (34 %). There was no difference in readmission (pre: 13 % vs. post:11.5 %, p = 0.398). There were fewer readmissions in post-pathway patients amongst MIS, low-intermediate risk, and Combination patients (all p > 0.1). 114 (8.4 %) patients required IRPs. Time-to-readmission and time-to-IR-procedure plots demonstrated lower plateaus and flatter slopes for MIS/low-intermediate-risk pathways post-pathway implementation (p < 0.001). CONCLUSION RSPHPs can reliably stratify patients by risks of readmission or need for an IR procedure by predicting the most frequent period for these events.

Abstract
INTRODUCTION There remains an unmet need for safe and cost-effective adjunctive treatment of advanced colorectal cancer (CRC). The omega-3 polyunsaturated fatty acid eicosapentaenoic acid (EPA) is safe, well-tolerated and has anti-inflammatory as well as antineoplastic properties. A phase 2 randomised trial of preoperative EPA free fatty acid 2 g daily in patients undergoing surgery for CRC liver metastasis showed no difference in the primary endpoint (histological tumour proliferation index) compared with placebo. However, the trial demonstrated possible benefit for the prespecified exploratory endpoint of postoperative disease-free survival. Therefore, we tested the hypothesis that EPA treatment, started before liver resection surgery (and continued postoperatively), improves CRC outcomes in patients with CRC liver metastasis. METHODS AND ANALYSIS The EPA for Metastasis Trial 2 trial is a randomised, double-blind, placebo-controlled, phase 3 trial of 4 g EPA ethyl ester (icosapent ethyl (IPE; Vascepa)) daily in patients undergoing liver resection surgery for CRC liver metastasis with curative intent. Trial treatment continues for a minimum of 2 years and maximum of 4 years, with 6 monthly assessments, including quality of life outcomes, as well as annual clinical record review after the trial intervention. The primary endpoint is CRC progression-free survival. Key secondary endpoints are overall survival, as well as the safety and tolerability of IPE. A minimum 388 participants are estimated to provide 247 CRC progression events during minimum 2-year follow-up, allowing detection of an HR of 0.7 in favour of IPE, with a power of 80% at the 5% (two sided) level of significance, assuming drop-out of 15%. ETHICS AND DISSEMINATION Ethical and health research authority approval was obtained in January 2018. All data will be collected by 2025. Full trial results will be published in 2026. Secondary analyses of health economic data, biomarker studies and other translational work will be published subsequently. TRIAL REGISTRATION NUMBER NCT03428477.

Abstract
INTRODUCTION Small liver tumours are difficult to identify during hepatectomy, which prevents curative tumour excision. Preoperative marking is a standard practice for small, deep-seated tumours in other solid organs; however, its effectiveness for liver tumours has not been validated. The objective of this study is to evaluate the effectiveness of preoperative markings for curative resection of small liver tumours. METHODS AND ANALYSIS This is an open-label, single-arm, single-centre, phase II study. Patients with liver tumours of ≤15 mm requiring hepatectomy will be enrolled and will undergo preoperative marking by placing a microcoil near the tumour using either the percutaneous or transvascular approach. The tumours, including the indwelling markers, will be excised. The primary endpoint will be the successful resection rate of liver tumours, defined as achieving a surgical margin of ≥5 mm and ≤15 mm. Secondary endpoints will include the results of preoperative marking and hepatectomy. ETHICS AND DISSEMINATION Ethical approval for this trial was obtained from the Ethical Committee for Clinical Research of Hiroshima University, Japan. The results will be published at an academic conference or by submitting a paper to a peer-reviewed journal. TRIAL REGISTRATION NUMBER jRCTs062220088.

Abstract
Hepatobiliary resections are among the most complex and technically challenging surgical procedures. Even though robust evidence showed that complex surgical procedures such as hepatobiliary surgery have better short- and long-term outcomes and lower mortality rate when performed in high-volume centers, the minimal criteria of centers that can perform hepatobiliary activity are not clearly defined. We conducted a retrospective population study of patients who underwent hepatobiliary surgery for malignant disease in a single Italian administrative region (Veneto) from 2010 to 2021 with the aim to investigate the hospitals annual surgical volume for hepatobiliary malignant diseases and the effect of hospital volume on in-hospital, 30- and 90-day postoperative mortality. The centralization process of hepatobiliary surgery in Veneto is rapidly increasing over the past 10 years (rate of performed in highly specialized centers increased from 62% in 2010 to 78% in 2021) and actually it is really established. The crude and adjusted (for age, sex, Charlson Index) mortality rate after hepatobiliary surgery resulted significantly lower in centers with high-volume activity compared to them with low-volume activity. In the Veneto region, the "Hub and Spoke" model led to a progressive centralization of liver and biliary cancer treatment. High surgical volume has been confirmed to be related to better outcomes in terms of mortality rate after hepatobiliary surgical procedures. Further studies are necessary to clearly define the minimal criteria and associated numerical cutoffs that can help define the characteristics of centers that can perform hepatobiliary activities.

Abstract
INTRODUCTION Liver resection carries a high risk for extensive bleeding and need for blood transfusions, which is associated with significant negative impact on outcome. In malignant disease, the most common indication for surgery, it also includes increased risk for recurrence of cancer. Argipressin decreases liver and portal blood flow and may have the potential to reduce bleeding during liver surgery, although this has not been explored. METHOD AND ANALYSIS ARG-01 is a prospective, randomised, placebo-controlled, double-blinded study on 248 patients undergoing liver resection at Sahlgrenska University Hospital, Sweden. Patients will be randomised to one of two parallel groups, infusion of argipressin or normal saline administered peroperatively. The primary endpoint is peroperative blood loss. Secondary outcomes include need for blood transfusion, perioperative variables, length of hospital stay, the inflammatory response, organ damage markers and complications at 30 days. ETHICS AND DISSEMINATION The study is enrolling patients since March 2022. The trial is approved by the Swedish Ethical Review Authority (Dnr 2021-03557) and the Swedish Medical Product Agency (Dnr 5.1-2021-90115). Results will be announced at scientific meetings and in international peer-reviewed journals. TRIAL REGISTRATION NUMBER ClinicalTrials.gov, NCT05293041 and EudraCT, 2021-001806-32.

Abstract
PURPOSE We aimed at exploring indocyanine green (ICG) fluorescence wide spectrum of applications in hepatobiliary surgery as can result particularly useful in robotic liver resections (RLR) in order to overcome some technical limitations, increasing safety, and efficacy. METHODS We describe our experience of 76 RLR performed between March 2020 and December 2022 exploring all the possible applications of pre- and intraoperative ICG administration. RESULTS Hepatocellular carcinoma and colorectal liver metastases were the most common indications for RLR (34.2% and 26.7% of patients, respectively), and 51.3% of cases were complex resections with high IWATE difficulty scores. ICG was administered preoperatively in 61 patients (80.3%), intraoperatively in 42 patients (55.3%) and in both contexts in 25 patients (32.9%), with no observed adverse events. The most frequent ICG goal was to achieve tumor enhancement (59 patients, 77.6%), with a success rate of 94.9% and the detection of 3 additional malignant lesions. ICG facilitated evaluation of the resection margin for residual tumor and perfusion adequacy in 33.9% and 32.9% of cases, respectively, mandating a resection enlargement in 7.9% of patients. ICG fluorescence allowed the identification of the transection plane through negative staining in the 25% of cases. Vascular and biliary structures were visualized in 21.1% and 9.2% of patients, with a success rate of 81.3% and 85.7%, respectively. CONCLUSION RLR can benefit from the routine integration of ICG fluoresce evaluation according to each individual patient and condition-specific goals and issues, allowing liver functional assessment, anatomical and vascular evaluation, tumor detection, and resection margins assessment.

Abstract
BACKGROUND Celiac axis stenosis (CAS) often is an incidental finding in terms of diagnostic for hepatobiliary surgery since most cases remain asymptomatic. It remains unclear whether CAS is a risk factor for postoperative complications after hepatobiliary surgery. Therefore, the aim of this study was to evaluate the impact of an asymptomatic CAS on the postoperative morbidity and survival of patients undergoing hepatobiliary surgery. METHODS We retrospectively analyzed CT scans and clinicopathological data of 250 consecutive patients undergoing hepatobiliary surgery between 2011 and 2018 in our tertiary center. We compared the postoperative course between patients with and without an incidental CAS as well as their overall survival. RESULTS CAS was caused by atherosclerotic stenosis in 16 (64%) patients, by ligamentous stenosis in 4 (16%) and by combined conditions in 5 cases (20%). Mean age of patients in the CAS group was significantly higher in comparison to patients of the non-CAS group (71.0 vs. 59.1 years, p < 0.001). Major hepatectomy was conducted in 40% of the CAS patients and 19.6% of non-CAS patients, respectively (p = 0.036). Interestingly, no statistically significant differences in postoperative morbidity (40 vs. 46.2%, p = 0.673) or in overall survival between the groups (41.3 vs. 51.9 months, p = 0.611) were observed. CONCLUSION Our analysis found no correlation between an asymptomatic celiac axis stenosis and postoperative complications or overall survival after hepatobiliary surgery. Which impact the incidental CAS may have in highly complex cases remains unclear. Further studies are needed to identify patients who benefit from CAS treatment before hepatobiliary surgery.

Abstract
OBJECTIVES Preoperative hypoalbuminaemia is associated with adverse outcome, including increased postoperative mortality in cardiovascular surgery, neurosurgery, trauma and orthopaedic surgery. However, much less is known about the association between preoperative serum albumin and clinical outcomes after liver surgery. In this study, we sought to determine whether hypoalbuminaemia before partial hepatectomy is associated with a worse postoperative outcome. DESIGN Observational study. SETTING University Medical Centre in Germany. PARTICIPANTS We analysed 154 patients enrolled in the perioperative PHYsostigmine prophylaxis for liver resection patients at risk for DELIrium and postOperative cognitive dysfunction (PHYDELIO) trial with a preoperative serum albumin assessment. Hypoalbuminaemia was defined as serum albumin <35 g/L. Subgroups classified as hypoalbuminaemia and non-hypoalbuminaemia consisted of 32 (20.8%) and 122 (79.2%) patients, respectively. OUTCOME MEASURES The outcome parameters of interest were postoperative complications according to Clavien (moderate: I, II; major: ≥III), length of intensive care unit (ICU) stay, length of hospital stay and survival rates 1 year after surgery. RESULTS Preoperative hypoalbuminaemia was associated with the occurrence of major postoperative complications (OR 3.051 (95% CI 1.197 to 7.775); p=0.019) after adjusting for age, sex, randomisation, American Society of Anesthesiologists physical status, preoperative diagnosis and Child-Pugh class. Both ICU and hospital lengths of stay were significantly prolonged in patients with preoperative hypoalbuminaemia (OR 2.573 (95% CI 1.015 to 6.524); p=0.047 and OR 1.296 (95% CI 0.254 to 3.009); p=0.012, respectively). One-year survival was comparable between patients with and without hypoalbuminaemia. CONCLUSIONS We found that low serum albumin before surgery was associated with a worse short-term outcome after partial hepatectomy, which strengthens the prognostic value of serum albumin in the setting of liver surgery.

Abstract
This study analyzed records of 200 patients who underwent hepatobiliary surgery to identify factors that contribute to lower extremity venous thromboembolism (VTE). 19 patients (9.50%) developed lower extremity deep vein thrombosis. Univariate analysis revealed significant differences between the study group and the control group in terms of age, body mass index, previous thromboembolic history, hypertension, type 2 diabetes, hyperlipidemia, smoking history, times of lower extremity venipuncture, operation time, postoperative bedrest time, postoperative platelet count, postoperative D-dimer level, and postoperative C-reactive protein level (P<0.05). Multivariable logistic regression analysis identified age ≥60 years, body mass index ≥24 kg/m2, previous history of thromboembolism, hypertension, type 2 diabetes mellitus, hyperlipidemia, smoking history, number of lower extremity venipunctures ≥5, operation time ≥2 hours, postoperative bedrest time ≥48 hours, postoperative blood platelet count ≥300×109/L, postoperative D-dimer level ≥200 g/L, and postoperative C-reactive protein ≥8.0 mg/L as significant predisposing factors for lower extremity VTE. The study concludes that patients undergoing hepatobiliary surgery are at an increased risk of developing lower extremity VTE, and prevention strategies must be tailored to each patient's unique set of risk factors. This includes careful management of postoperative bed rest, monitoring of platelet count, D-dimer and C-reactive protein levels, controlling hypertension, type 2 diabetes mellitus, hyperlipidemia, and cessation of smoking. This study highlights the importance of early identification of patients at high risk of lower extremity VTE following hepatobiliary surgery and comprehensive prevention measures.

Abstract
The revision of the medical device regulation (MDR) legislation by the European Union and supplementations by the member states has been implemented for good reasons but causes dramatic side effects. It is no longer allowed to produce some rarely used medical devices by various manufacturers that have been successfully used for decades. Before production, a new application to the MDR would be necessary, which is not a realistic business case for companies producing rarely used devices. This problem currently relates to the Kehr T‑drain made from soft rubber or latex that has been in use since the late nineteenth century. A surgically placed T‑drain, although rarely necessary nowadays, is still in use worldwide for special indications in an attempt to avoid severe complications. These special indications include complex hepato-pancreato-biliary (HPB) procedures and perforations of the upper gastrointestinal (GI) tract where T‑drains may be used to secure the hepatojejunostomy or to create a stable fistula. The HPB working group (CALGP) of the German Society of General and Visceral Surgery (DGAV) provides a statement from a surgical perspective on this matter after a survey of all its members. Politics should be very careful not to generalize when implementing useful new regulations at a European and national level. Established and comprehensible treatment concepts should not be restricted and exemption permits should be quickly granted in these cases because the discontinuation of these niche products may lead to potential patient safety issues and even fatalities.

Abstract
BACKGROUND Near-infrared fluorescent cholangiography (NIRFC) with indocyanine green (ICG) as the developer yields clear visualization of the extrahepatic bile ducts and is effective in identifying key structures. Here, we analyzed and compared the surgical outcomes of fluorescent and conventional laparoscopy in cholecystectomy of various difficulties and then assessed the value of NIRFC. MATERIALS AND METHODS This retrospective study collected clinical data from partial patients who underwent laparoscopic cholecystectomy (LC) at the Department of Hepatobiliary and Pancreatic Surgery, Zhongnan Hospital of Wuhan University between 2020 and 2021. The study subjects were classified into ICG-assisted and white-light laparoscopy. Two cohorts with homogeneous baseline status were selected based on 1:1 ratio propensity score matching (PSM). Multivariate logistic regression analysis was performed to predict independent risk factors for LC difficulty. Thereafter, the matched cases were classified into difficult and easy subgroups by combining difficulty score and gallbladder disease type, and then the surgical outcomes of the two groups were compared. RESULTS This study included a total of 624 patients. The patients were classified into the ICG group (n = 218) and the non-ICG group (n = 218) after a 1:1 ratio PSM. Our data showed significant differences between the groups in operative time (P = 0.020), blood loss (P = 0.016), length of stay (P = 0.036), and adverse reaction (P = 0.023). Stratified analysis demonstrated that ICG did not significantly improve the surgical outcomes in simple cases (n = 208). On the other hand, in difficult cases (n = 228), NIRFC shortened operative time (P = 0.003) and length of stay (P = 0.015), reduced blood loss (P = 0.028) and drain placement rate (P = 0.015), and had fewer adverse reactions (P = 0.023). The data showed that five cases were converted to laparotomy while two cases had minor bile leaks in the non-ICG group. There was no bile duct injury (BDI) in all the cases. Furthermore, high BMI, history of urgent admission and abdominal surgery, palpable gallbladder, thickened wall, and pericholecystic collection were risk factors for surgical difficulty. CONCLUSION ICG-assisted NIRFC provides real-time biliary visualization. In complicated conditions such as acute severe inflammation, dense adhesions, and biliary variants, the navigating ability of fluorescence can enhance the operation progress, reduce the possibility of conversion or serious complications, and improve the efficiency and safety of difficult LC.

Abstract
INTRODUCTION Major surgery is associated with a high risk for postoperative complications, leading to an increase in mortality and morbidity, particularly in frail patients with a reduced cardiopulmonary reserve. Prehabilitation, including aerobic exercise training, aims to improve patients' physical fitness before major surgery and reduce postoperative complications, length of hospital stay and costs. The purpose of the study is to assess the usability, validity and safety of an app-based endurance exercise software in accordance with the Medical Device Regulation using wrist-worn wearables to measure heart rate (HR) and distance. METHODS AND ANALYSIS The PROTEGO MAXIMA trial is a prospective, interventional study with patients undergoing major elective surgery, comprising three tasks. Tasks I and II aim to assess the usability of the app, using evaluation questionnaires and usability scenarios. In Task IIIa, patients will undergo a structured risk assessment by the Patronus App, which will be correlated with the occurrence of postoperative complications after 90 days (non-interventional).

Abstract
INTRODUCTION Liver resection is the only curative treatment for colorectal liver metastases (CLM). Resectability decision-making is therefore a key determinant of outcomes. Wide variation has been demonstrated in resectability decision-making, despite the existence of criteria. This paper summarises a study protocol to evaluate the potential added value of two novel assessment tools in assessing CLM technical resectability: the Hepatica preoperative MR scan (MR-based volumetry, Couinaud segmentation, liver tissue characteristics and operative planning tool) and the LiMAx test (hepatic functional capacity). METHODS AND ANALYSIS This study uses a systematic multistep approach, whereby three preparatory workstreams aid the design of the final international case-based scenario survey:Workstream 1: systematic literature review of published resectability criteria.Workstream 2: international hepatopancreatobiliary (HPB) interviews.Workstream 3: international HPB questionnaire.Workstream 4: international HPB case-based scenario survey.The primary outcome measures are change in resectability decision-making and change in planned operative strategy, resulting from the novel test results. Secondary outcome measures are variability in CLM resectability decision-making and opinions on the role for novel tools. ETHICS AND DISSEMINATION The study protocol has been approved by a National Health Service Research Ethics Committee and registered with the Health Research Authority. Dissemination will be via international and national conferences. Manuscripts will be published. REGISTRATION DETAILS The CoNoR Study is registered with ClinicalTrials.gov (registration number NCT04270851). The systematic review is registered on the PROSPERO database (registration number CRD42019136748).

Abstract
INTRODUCTION Postoperative health-related quality of life (HRQoL) is an essential outcome in oncological surgery, particularly for elderly patients undergoing high-risk surgery. Previous studies have suggested that, on average, HRQoL returns to premorbid normal levels in the months following major surgery. However, the averaging of effect over a studied cohort may hide the variation of individual HRQoL changes. The proportions of patients who have a varied HRQoL response (stable, improvement, or a deterioration) after major oncological surgery is poorly understood. The study aims to describe the patterns of these HRQoL changes at 6 months after surgery, and to assess the patients and next-of-kin regret regarding the decision to undergo surgery. METHODS AND ANALYSIS This prospective observational cohort study is carried out at the University Hospitals of Geneva, Switzerland. We include patients over 18 years old undergoing gastrectomy, esophagectomy, pancreas resection or hepatectomy. The primary outcome is the proportion of patients in each group with changes in HRQoL (improvement, stability or deterioration) 6 months after surgery, using a validated minimal clinically important difference of 10 points in HRQoL. The secondary outcome is to assess whether patients and their next-of-kin may regret their decision to undergo surgery at 6 months. We measure the HRQoL using the EORTC QLQ-C30 questionnaire before and 6 months after surgery. We assess regret with the Decision Regret Scale (DRS) at 6 months after surgery. Key other perioperative data include preoperative and postoperative place of residence, preoperative anxiety and depression (HADS scale), preoperative disability (WHODAS V.2.0), preoperative frailty (Clinical Frailty Scale), preoperative cognitive function (Mini-Mental State Examination) and preoperative comorbidities. A follow-up at 12 months is planned. ETHICS AND DISSEMINATION The study was first approved by the Geneva Ethical Committee for Research (ID 2020-00536) on 28 April 2020. The results of this study will be presented at national and international scientific meetings, and publications will be submitted to an open-access peer-reviewed journal.

Abstract
PURPOSE To review surgical management of extrahepatic portal vein obstruction (EHPVO) at Red Cross War Memorial Children's Hospital and compare MesoRex shunt (MRS) with distal splenorenal shunt (DSRS). METHODS This is a single-centre retrospective review documenting pre- and post-operative data in 21 children. Twenty-two shunts were performed, 15 MRS and 7 DSRS, over an 18-year period. Patients were followed up for a mean of 11 years (range 2-18). Data analysis included demographics, albumin, prothrombin time (PT), partial thromboplastin time (PTT), International normalised ratio (INR), fibrinogen, total bilirubin, liver enzymes and platelets before the operation and 2 years after shunt surgery. RESULTS One MRS thrombosed immediately post-surgery and the child was salvaged with DSRS. Variceal bleeding was controlled in both groups. Significant improvements were seen amongst MRS cohort in serum albumin, PT, PTT, and platelets and there was a mild improvement in serum fibrinogen. The DSRS cohort showed only a significant improvement in the platelet count. Neonatal umbilic vein catheterization (UVC) was a major risk for Rex vein obliteration. CONCLUSION In EHPVO, MRS is superior to DSRS and improves liver synthetic function. DSRS does control variceal bleeding but should only be considered when MRS is not technically feasible or as a salvage procedure when MRS fails.

Abstract
OBJECTIVES ABO and Rh blood group systems are the major factors affecting the blood transfusion safety. The frequency and distribution of these blood group systems vary worldwide. We aimed to determine the frequency and distribution of ABO and Rh blood group systems among first-time blood donors at the Northern Zone Blood Transfusion Center in Kilimanjaro, Tanzania. DESIGN Cross-sectional descriptive population-based study. SETTING Data on ABO and Rh blood group systems were obtained and analysed from the Northern Zone Blood Transfusion Center among first-time blood donors. PARTICIPANTS There were 65 535 first-time blood donors aged 15-55 years who donated at the Northern Zone Blood Transfusion Center from January 2017 to December 2019. OUTCOME MEASURES The percentage of ABO and Rh blood group systems among different categories of blood donors was calculated. RESULTS Retrospective data from Blood Establishment Computer System of 65 535 first-time blood donors were analysed in the present study. The mean age of the blood donors was 30.6±11.2 years (range: 15-55 years). The vast majority of the blood donors 84.2% (n=55 210) were men. Also, the majority 69.6% (n=45 595) were aged ≥35 years. Blood group O was the most common blood group which was found in over half 52.4% (n=34 333) of the blood donors and majority 95.3% (n=62 461) of the donors were Rh positive. Moreover, the majority 78.3% (n=51 336) were voluntary donors and the remaining 21.7% (n=14 199) were replacement donors. CONCLUSION Majority of the donors had blood group O and also the vast majority of the donors were Rh positive. Considering the large size of our study population, this has provided a more comprehensive information regarding the frequency and patterns of ABO and Rh blood group systems in Tanzania. The observed association of blood group A with one of the regions from which donors were coming from, is intriguing and further studies may confirm possible related genetic evolution.

Abstract
INTRODUCTION Surgical site infection (SSI) after laparotomy still represents the most frequent postoperative complicationin abdominal surgery. The effectiveness of reducing SSI rates by intra-operative irrigation of the incisional wound with antiseptic solutions or saline has been much debated, and recommendations on its use are divergent. Therefore, we aim to conduct a systematic review and meta-analysis, focusing specifically on procedures by laparotomy and considering recent evidence only. METHODS AND ANALYSIS The systematic review and meta-analysis were conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. On 1 July 2022, PubMed/MEDLINE, Cochrane, Central Register of Controlled Trials and EMBASE were searched for the following predefined terms: (Surgical site infection) AND ((irrigation) OR (wound irrigation) OR (lavage)) AND ((abdominal surgery) OR (laparotomy). The search was limited to peer-revied publications, dating after 1 January 2000 in English or German language. Systematic reviews and meta-analyses were included for reference screening. Case reports, case series, non-systematic reviews and studies without follow-up information were excluded. The primary outcome is the rate of postoperative SSI after abdominal surgery by laparotomy. Meta-analysis is pooled using the Mantel-Haenszel method for random effects. The risk of bias in randomised studies will be assessed using the Cochrane developed RoB 2-tool, and the ROBINS-I tool for non-randomised studies. Completion of the analysis and publication is planned in March 2023. ETHICS AND DISSEMINATION Ethical approval is not necessary for this study, as no new data will be collected. The results of the final study will be published in a peer-reviewed open-access journal. PROSPERO REGISTRATION NUMBER CRD42022321458.

Abstract
BACKGROUND Subcuticular suture has proven to reduce superficial incisional SSI (si-SSI) in clean surgery. However, question remains regarding clean-contaminated procedures. The aim of this study is to assess if subcuticular suture is superior to staples in reducing si-SSI incidence in elective HBP surgery. METHODS Single-centre, open-label, parallel, pragmatic randomized clinical trial conducted at a referral tertiary Hospital between January 2020 and April 2022. Patients eligible for elective HBP surgery were randomly assigned (1:1) to subcuticular suture or surgical staples wound closure using a minimisation method based on previously confirmed risk factors. The primary endpoint was the incidence of si-SSI. Considered secondary endpoints were major postoperative morbidity in both groups, additional wound complications, median hospital length of stay and need for re-hospitalisation. RESULTS Of the 379 patients, 346 patients were randomly assigned to receive skin closure with staples (n = 173) or subcuticular suture (n = 173). After further exclusion of 11 participants, 167 and 168 patients, respectively in the control and the experimental group received their allocated intervention. For the primary endpoint, no significant differences in si-SSI rate were found: 17 (9.82%) staples group vs. 8 (4.62%) in subcuticular suture group (p = 0.062). Subset analysis confirmed absence of significant differences. As for secondary endpoints, overall wound complications did not differ significantly between two procedures: 19 (10.98%) vs. 10 (6.35%) (p = 0.127). There were no treatment related adverse events. However, occurrence of si-SSI contributed to major postoperative morbidity in both groups (p < 0.001 and p = 0.018) and to a substantially prolonged postoperative hospitalization (p = 0.015). CONCLUSIONS Subcuticular suture might offer a relative benefit for skin closure reducing incidence of si-SSI after elective HBP surgery, although this was found not to be clinically relevant. Yet, this should not be interpreted as equivalence among both treatments. Therefore, wound closure strategy should not be based only on these grounds.

Abstract
BACKGROUND AND AIM A potential solution to the deceased organ shortage is to include live organ donations and to identify patients with lower rates of HCC recurrence to fairly allocate liver grafts. Our aims were to detect the long-term outcomes of LDLT versus DDLT for HCC and predictors of recurrence after transplantation. METHODS PubMed, Scopus, Web of Science, Cochrane library were searched for eligible studies from inception to July 2021 and a systematic review and meta-analysis were done. RESULTS 35 studies with a total of 7822 patients were included. The 1-, 3-, 4 year-OS showed trivial improvement for LDLT recipients. However, the two modalities had similar 5-, 6- and 10-year OS. A significant improvement in the ITT-OS was observed for LDLT recipients. Regarding the DFS and recurrence after transplantation, no significant difference was observed between LDLT and DDLT. In addition to that, the pooled hazard ratio of the included studies showed that Milan criteria, level of AFP, presence of vascular invasion, tumor differentiation were significant predictors of recurrence. CONCLUSION The cancer biology (not the graft type) is the most important determinant of recurrence and survival after LT. However, LDLT provided much better survival benefits to HCC patients especially in regions that suffer from low deceased organ availability.

Peritoneal antiseptic irrigation to prevent surgical site infection after laparotomy for hepatobiliary or gastrointestinal surgery (PAISI)-protocol for a randomized controlled study.

Abstract
BACKGROUND Postoperative surgical site infections (SSIs) remain common after laparotomy for resections of the gastrointestinal or hepatobiliary tract. Especially organ/space infections (CDC class III SSI) can be life-threatening, require relaparotomy, intensive care or interventional drainage of intraabdominal abscesses. The PAISI study aims to investigate whether the use of prophylactic peritoneal irrigation with NaOCl/HOCl solution can reduce the SSI rates following laparotomy for resections of the gastrointestinal or hepatobiliary tract, compared to standard irrigation with physiological electrolyte solution (Ringer's solution). Secondarily, to evaluate whether the use of prophylactic peritoneal irrigation with NaOCl/HOCl solution can reduce postoperative morbidity and mortality as well as the rate of re-operations and length of hospital stay. METHODS PAISI is a prospective, randomized, observer- and patient-blinded, monocentric, two-arm surgical study in an adaptive parallel groups design, comparing peritoneal and wound irrigation with NaOCl/HOCl (50/50ppm) solution to irrigation with Ringer's solution. The primary endpoint of the study is the SSI rate within 30 days postoperatively. Since there is no data on incidence rates from randomized clinical trials, the rates for sample size calculation were estimated according to the clinical experience at our institution. Therefore, the study design includes one unblinded look at the data by a second statistician, which will be performed after half of the patients reached the primary endpoint. This interim information will be used to check the assumptions and if needed, the sample size will be adjusted. The O'Brien-Fleming spending function is used to determine the efficacy test boundary and the non-binding futility boundary. The one-sided z-test (Group sequential test of two proportions) at the 2.5% significance level with a total of two looks at the data will have overall 80% power. DISCUSSION The results of this study will provide high-level evidence for future research and clinical recommendations regarding the use of NaOCl/HOCl solution in abdominal surgery and provide the participating patients the opportunity of a potentially improved treatment.

Abstract
PURPOSE The aim of this study was to review the incidence, spectrum and investigation of liver masses presenting to our tertiary liver unit. METHODS A retrospective single-centre cohort study of paediatric patients (age < 16 years) diagnosed with a liver mass who were investigated at a UK paediatric hepatobiliary tertiary referral centre. Data relating to the clinical findings at presentation, source of referral, diagnostic investigations and histopathology findings were recorded and analysed. RESULTS 107 patients were identified between July 2012 and July 2019 (55 females). 69 (64%) patients had benign liver lesions, whereas the remaining 38 (36%) were found to have malignant masses. The liver lesions were most commonly detected incidentally (33%) with the second most common presentation being with palpable mass (29%). 82 (77%) patients were referred from other hospitals. All patients underwent USS, 74% MRI, 36% CT, 5% CEUS, 1% PET and 5% HIDA scan with 47% ultimately undergoing biopsy. 72% of patients had AFP measured. The most common benign liver masses were haemangioma 33 (48%), hepatic cyst 17 (25%) and FNH 12 (19%). Amongst the malignant lesions, 29 (76%) were hepatoblastoma and 3 (8%) were hepatocellular carcinoma. CONCLUSIONS This large review series demonstrates that just over 1/3 of patients presenting to a paediatric tertiary referral centre with a focal liver lesion had neoplastic liver lesions, despite the published literature commonly stating that 2/3 of paediatric liver masses are malignant.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) remains a major clinical problem as more than half of these cases recur after radical resection. Natural killer (NK) cells are at the forefront of the innate immune system and attack microcarcinomas and circulating tumour cells. The objective of this study was to evaluate the feasibility and toxicity of peripheral blood CD34+ stem cell-derived NK cell infusion after radical hepatectomy for HCC. METHODS AND ANALYSIS This is an open-label, single-arm, single-centre phase I study. Patients who have undergone initial hepatectomy for HCC with three or more risk factors for recurrence (≥10 ng/mL of Alpha fetoprotein (AFP), ≥360 mAU/mL of PIVKA-II, multiple tumours and ≥3 peripheral blood circulating tumour cells) will be enrolled and be treated with three peripheral blood CD34+ stem cell-derived NK cell infusions every 3 months. The primary endpoint will be safety assessment including the type and severity of adverse events, frequency of occurrence and duration of occurrence. The secondary endpoints will include survival, effect of immune response and clinical laboratory test results. ETHICS AND DISSEMINATION Ethical approval of the trial was obtained from the Certified Committee for Regenerative Medicine Hiroshima University in Japan. The trial results will be shared with the scientific community at international conferences and by publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER jRCTb060200020.

Abstract
INTRODUCTION To date, no pancreatic stump closure technique has been shown to be superior to any other in distal pancreatectomy. Although several studies have shown a trend towards better results in transection using a radiofrequency device (radiofrequency-assisted transection (RFT)), no randomised trial for this purpose has been performed to date. Therefore, we designed a randomised clinical trial, with the hypothesis that this technique used in distal pancreatectomies is superior in reducing clinically relevant postoperative pancreatic fistula (CR-POPF) than mechanical closures. METHODS AND ANALYSIS TRANSPAIRE is a multicentre randomised controlled trial conducted in seven Spanish pancreatic centres that includes 112 patients undergoing elective distal pancreatectomy for any indication who will be randomly assigned to RFT or classic stapler transections (control group) in a ratio of 1:1. The primary outcome is the CR-POPF percentage. Sample size is calculated with the following assumptions: 5% one-sided significance level (α), 80% power (1-β), expected POPF in control group of 32%, expected POPF in RFT group of 10% and a clinically relevant difference of 22%. Secondary outcomes include postoperative results, complications, radiological evaluation of the pancreatic stump, metabolomic profile of postoperative peritoneal fluid, survival and quality of life. Follow-ups will be carried out in the external consultation at 1, 6 and 12 months postoperatively. ETHICS AND DISSEMINATION TRANSPAIRE has been approved by the CEIM-PSMAR Ethics Committee. This project is being carried out in accordance with national and international guidelines, the basic principles of protection of human rights and dignity established in the Declaration of Helsinki (64th General Assembly, Fortaleza, Brazil, October 2013), and in accordance with regulations in studies with biological samples, Law 14/2007 on Biomedical Research will be followed. We have defined a dissemination strategy, whose main objective is the participation of stakeholders and the transfer of knowledge to support the exploitation of activities.

Abstract
INTRODUCTION Viability assessment of the graft is essential to lower the risk of liver transplantation (LT) failure and need for emergency retransplantation, however, this still relies mainly on surgeon's experience. Post-LT graft function recovery assessment is also essential to aid physicians in the management of LT recipients and guide them through challenging decision making.This study aims to trial the use of indocyanine green clearance test (IGT) in the donor as an objective tool to assess graft viability and in the recipient to assess graft function recovery after LT. METHODS AND ANALYSIS This is an observational prospective single-centre study on consecutive liver transplant donors and recipients. PRIMARY OBJECTIVE To determine the capability of IGT of predicting graft viability at the time of organ retrieval. Indocyanine green will be administered to the donor and the plasma disappearance rate (PDR) measured using the pulsidensitometric method. Some 162 IGT donor procedures will be required (α, 5%; β, 20%) using an IGT-PDR cut-off value of 13% to achieve a significant discrimination between viable and non-viable grafts. SECONDARY OBJECTIVE IGT-PDR will be measured at different time-points in the LT recipient: during the anhepatic phase, after graft reperfusion, at 24 hours, on day 3 and day 7 after LT. The slope of IGT values from the donor to the recipient will be evaluated for correlation with the development of early allograft dysfunction. ETHICS AND DISSEMINATION This research protocol was approved by Fondazione Policlinico Universitario Agostino Gemelli IRCCS Ethics Committee (reference number: 0048466/20, study ID: 3656) and by the Italian National Transplant Center (CNT) (reference number: Prot.11/CNT2021). Liver recipients will be required to provide written informed consent. Results will be published in international peer-reviewed scientific journals and presented in congresses. TRIAL REGISTRATION NUMBER NCT05228587.

Abstract
INTRODUCTION Following a cancer diagnosis, patients and their caregivers face crucial decisions regarding goals of care and treatment, which have consequences that can persist throughout their cancer journey. To foster informed and value-driven treatment choices, evidence-based information on outcomes relevant to patients is needed. Traditionally, clinical studies have largely focused on a few concrete and easily measurable outcomes such as survival, disease progression and immediate treatment toxicities. These outcomes do not capture other important factors that patients consider when making treatment decisions. Patient-centred outcomes (PCOs) reflect the patients' individual values, preferences, needs and circumstances that are essential to directing meaningful and informed healthcare discussions. Often, however, these outcomes are not included in research protocols in a standardised and practical fashion. This scoping review will summarise the existing literature on PCOs in gastrointestinal (GI) cancer care as well as the tools used to assess these outcomes. A comprehensive list of these PCOs will be generated for future efforts to develop a core outcome set. METHODS AND ANALYSIS This scoping review will follow Arksey and O'Malley's expanded framework for scoping reviews. We will systematically search Medline, Embase, CINAHL, Cochrane Library and APA PsycINFO databases for studies examining PCOs in the context of GI cancer. We will include studies published in or after the year 2000 up to the date of the final searches, with no language restrictions. Studies involving adult patients with GI cancers and discussion of any PCOs will be included. Opinion pieces, protocols, case reports and abstracts will be excluded. Two authors will independently perform two rounds of screening to select studies for inclusion. The data from full texts will be extracted, charted and summarised both quantitatively and qualitatively. ETHICS AND DISSEMINATION No ethics approval is required for this scoping review. Results will be disseminated through scientific publication and presentation at relevant conferences.

Abstract
Background The COVID-19 pandemic caused a global health crisis in 2020. This pandemic also had a negative impact on standard procedures in general surgery. Surgeons were challenged to find the best treatment plans for patients with acute cholecystitis. The aim of this study is to investigate the impact of the COVID-19 pandemic on the outcomes of laparoscopic cholecystectomies performed in a tertiary care hospital in Germany. Patients and methods We examined perioperative outcomes of patients who underwent laparoscopic cholecystectomy during the pandemic from March 22, 2020 (first national lockdown in Germany) to December 31, 2020. We then compared these to perioperative outcomes from the same time frame of the previous year. Results A total of 182 patients who underwent laparoscopic cholecystectomy during the above-mentioned periods were enrolled. The pandemic group consisted of 100 and the control group of 82 patients. Subgroup analysis of elderly patients (> 65 years old) revealed significantly higher rates of acute [5 (17.9%) vs. 20 (58.8%); p = 0.001] and gangrenous cholecystitis [0 (0.0%) vs. 7 (20.6%); p = 0.013] in the “pandemic subgroup”. Furthermore, significantly more early cholecystectomies were performed in this subgroup [5 (17.9%) vs. 20 (58.8%); p = 0.001]. There were no significant differences between the groups both in the overall and subgroup analysis regarding the operation time, intraoperative blood loss, length of hospitalization, morbidity and mortality. Conclusion Elderly patients showed particularly higher rates of acute and gangrenous cholecystitis during the pandemic. Laparoscopic cholecystectomy can be performed safely in the COVID-19 era without negative impact on perioperative results. Therefore, we would assume that laparoscopic cholecystectomy can be recommended for any patient with acute cholecystitis, including the elderly.

Abstract
INTRODUCTION Partial pancreatoduodenectomy (PD) is the treatment of choice for many malignant and benign diseases of the pancreatic head. Postoperative complication rates of up to 40% are regularly reported. One of the most common and potentially life-threatening complication is the postoperative pancreatic fistula (POPF). Parenchymal risk factors like main pancreatic duct diameter or texture of the pancreatic gland have already been identified in retrospective studies. The aim of this study is to evaluate the diagnostic value of parenchymal risk factors on POPF in a prospective manner. METHODS AND ANALYSIS All patients scheduled for elective PD at the Department of General, Visceral and Transplantation Surgery of the University of Heidelberg will be screened for eligibility. As diagnostic factors, diameter and texture of the pancreatic gland as well as radiological and histopathological features will be recorded. Furthermore, the new four class risk classification system by the International Study Group of Pancreatic Surgery (ISGPS) will be recorded. The postoperative course will be monitored prospectively. The primary endpoint will be the association of the main pancreatic duct size and the texture of the pancreatic gland on POPF according to the updated ISGPS definition. The diagnostic value of the above-mentioned factors for POPF will be evaluated in a univariable and multivariable analysis. ETHICS AND DISSEMINATION PARIS is a monocentric, prospective, diagnostic study to evaluate the association of parenchymal risk factors and the development of POPF approved by the Ethics Committee of the medical faculty of Heidelberg University (S-344/2019). Results will be available in 2022 and will be published at national and international meetings. With this knowledge, the intraoperative and perioperative decision-making process could be eased and improve the individual outcome of patient. TRIAL REGISTRATION NUMBER DRKS00017184.

Abstract
BACKGROUND Readmissions are costly and inconvenient for patients, and occur frequently in hepatopancreatobiliary (HPB) surgery practice. Readmission prediction tools exist, but most have not been designed or tested in the HPB patient population. METHODS Pancreatectomy and hepatectomy operation-specific readmission models defined as subspecialty readmission risk assessments (SRRA) were developed using clinically relevant data from merged 2014-15 ACS NSQIP Participant Use Data Files and Procedure Targeted datasets. The two derived procedure-specific models were tested along with 6 other readmission models in institutional validation cohorts in patients who had pancreatectomy or hepatectomy, respectively, between 2013 and 2017. Models were compared using area under the receiver operating characteristic curves (AUC). RESULTS A total of 16,884 patients (9169 pancreatectomy and 7715 hepatectomy) were included in the derivation models. A total of 665 patients (383 pancreatectomy and 282 hepatectomy) were included in the validation models. Specialty-specific readmission models outperformed general models. AUC characteristics of the derived pancreatectomy and hepatectomy SRRA (pancreatectomy AUC=0.66, hepatectomy AUC=0.74), modified Readmission After Pancreatectomy (AUC=0.76), and modified Readmission Risk Score for hepatectomy (AUC=0.78) outperformed general models for readmission risk: LOS/2 + ASA integer-based score (pancreatectomy AUC=0.58, hepatectomy AUC=0.66), LACE Index (pancreatectomy AUC=0.54, hepatectomy AUC=0.62), Unplanned Readmission Nomogram (pancreatectomy AUC=0.52, hepatectomy AUC=0.55), and institutional ARIA (pancreatectomy AUC=0.46, hepatectomy AUC=0.58). CONCLUSION HPB readmission risk models using 30-day subspecialty-specific data outperform general readmission risk tools. Hospitals and practices aiming to decrease readmissions in HPB surgery patient populations should use specialty-specific readmission reduction strategies.

Abstract
Introduction Hepatic epithelioid hemangioendothelioma (HEHE) is a rare tumor of vascular origin. Liver involvement is often multinodular simulating metastases. Herein, we report a rare case of HEHE mimicking liver metastases in a female patient. Case presentation A 43-years-old female patient, presented with complaints of pain in the right upper quadrant. Laboratory tests were all within the normal range. Abdominal ultrasound revealed multiple heterogeneous hypoechoic liver lesions. A thoracic and abdominopelvic computed tomography showed bilateral pulmonary micronodules with multiple hypodense hepatic nodules involving both lobes. Percutaneous ultrasound-guided biopsy with pathological study and immunohistochemistry staining revealed the diagnosis of hepatic epithelioid hemangioendothelioma. Discussion HEHE usually involves both liver lobes with three radiological presentations: single nodular, multiple nodular, or diffuse types, the diffuse type reflects an advanced stage. 3/4 of the cases are initially misdiagnosed as liver metastases or primary liver tumors. The pathological study with the immunochemistry stainings confirms the diagnosis. There is no standard treatment for HEHE due to its rarity and lack of prospective randomized studies. Conclusion HEHE is a rare tumor of vascular origin of unknown etiology with malignant potential and unpredictable course. The therapeutic management of this rare condition is not codified and is discussed on a case-by-case basis. Surgical treatment remains the best option with an excellent outcome. Hepatic epithelioid hemangioendothelioma is a rare tumor of vascular origin. The Clinical presentation and the radiological findings are not specific. Final Diagnosis is made upon pathological study and immunohistochemistry staining. Surgical treatment remain the treatment of choice.

Abstract
BACKGROUND Nursing during the perioperative period of hepatobiliary surgery is essential in the treatment and rehabilitation of patients. Personalized nursing gives full consideration to the personal characteristics of patients and encourages patients to participate in making decisions. However, compared to traditional nursing, there is insufficient evidence of the effectiveness of personalized nursing. This review sought to evaluate the effects of personalized nursing during the perioperative period of hepatobiliary surgery. METHODS A meta-analysis was conducted of articles published from 2010 to 2021. To identify the relevant electronic publications, the PubMed, Web of Science, Embase, CNKI, and Wanfang databases were searched for articles comparing the clinical efficacy of personalized nursing with that of traditional nursing. The standardized mean difference (SMD) and odds ratio (OR) with 95% confidence interval (CI) were used to calculate the aggregated effect index. RESULTS Of the 286 records retrieved from the search of the databases, 12 studies, comprising 1,039 patients, met the screening criteria. The meta-analysis showed that personalized nursing improved patients' levels of satisfaction with nursing (OR =6.871; 95% CI: 3.708-12.734), and decreased the incidence of adverse reactions significantly (OR =0.234; 95% CI: 0.153-0.357). Compared to traditional nursing, personalized nursing reduced patients' average hospitalization time, the time it took to get out of bed for the first time after surgery, the time it took to first eat after surgery, and the time it took to first exhaust after surgery. Additionally, patients who received personalized nursing had significantly reduced Self-rating Anxiety Scale (SAS) scores and Self-rating Depression Scale (SDS) scores than patients who received traditional nursing. DISCUSSION The application of personalized nursing to patients undergoing hepatobiliary surgery during the perioperative period improved patients' level of satisfaction with nursing, effectively reduced the incidence of adverse reactions, accelerated the recovery of hepatobiliary function after surgery, and relieved anxiety and depression; thus, personalized nursing is worthy of clinical application.

Abstract
With the continuous development of digital medicine, minimally invasive precision and safety have become the primary development trends in hepatobiliary surgery. Due to the specificity and complexity of hepatobiliary surgery, traditional preoperative imaging techniques such as computed tomography and magnetic resonance imaging cannot meet the need for identification of fine anatomical regions. Imaging-based three-dimensional (3D) reconstruction, virtual simulation of surgery and 3D printing optimize the surgical plan through preoperative assessment, improving the controllability and safety of intraoperative operations, and in difficult-to-reach areas of the posterior and superior liver, assistive robots reproduce the surgeon’s natural movements with stable cameras, reducing natural vibrations. Electromagnetic navigation in abdominal surgery solves the problem of conventional surgery still relying on direct visual observation or preoperative image assessment. We summarize and compare these recent trends in digital medical solutions for the future development and refinement of digital medicine in hepatobiliary surgery.

Abstract
BACKGROUND Blood loss is a major determinant of outcomes following hepatectomy. Robotic technology enables hepatobiliary surgeons to mimic open techniques for inflow control and parenchymal transection during major hepatectomy, increasing the ability to minimize blood loss and perform safe liver resections. METHODS Initial experience of 20 consecutive major robotic hepatectomies from November 2018 to July 2020 at two co-located institutions was reviewed. All cases were performed with extrahepatic inflow control and parenchymal transection with the laparoscopic cavitron ultrasonic surgical aspirator (CUSA), and a technical description is illustrated. Clinical characteristics, operative data, and surgical outcomes were retrospectively analyzed. RESULTS The median (range) patient age was 58 years (20-76) and the majority of 14 (70%) patients were ASA III-IV. There were 12 (60%) resections for malignancy and the median tumor size was 6.2 cm (1.2-14.6). Right or extended right hepatectomy was the most common procedure (12 or 60% of cases). There were 7 (35%) left or extended left hepatectomies and 1 (5%) central hepatectomy. The median operative time was 420 (177-622) minutes. Median estimated blood loss was 300 mL (25-800 mL). One (5%) case was converted to open. Two (10%) patients required blood transfusion. The median length of stay was 3 (1-6) days. Major complications included 1 (5%) Clavien-Dindo IIIa bile leak requiring percutaneous drainage placement. There was no 90-day mortality. CONCLUSION Advanced techniques to reduce blood loss in robotic hepatectomy may optimize safety and minimize morbidity in these complex minimally invasive procedures.

Abstract
Laparoscopic fenestration (LF) has recently been considered a standard procedure for nonparasitic symptomatic liver cysts. Here, we report a case of LF that was safely performed using real-time indocyanine green (ICG) fluorescence-guided surgery. A 74-year-old woman presented with right upper abdominal pain and poor dietary intake. The patient was diagnosed with symptomatic liver cysts and underwent LF. One hour before surgery, ICG (2.5 mg) was intravenously administered to the patient. ICG fluorescence imaging clearly showed the biliary ducts and distinguished the cysts from the liver parenchyma. We could resect only the cyst walls as wide as possible under the guidance of both white light and fluorescence imaging. There were no signs of postoperative symptom recurrence. Detection of ICG fluorescence in the liver parenchyma is as important as ICG cholangiography for fenestration. Laparoscopic liver cyst fenestration with real-time ICG fluorescence-guided surgery is safe and can be used as a standard procedure.

Abstract
Background A prognostic benefit of additive chemotherapy in patients following resection of metachronous colorectal liver metastases (CRLM) remains controversial. Therefore, the goal of this retrospective study was to investigate the impact of perioperative chemotherapy on disease-free survival (DFS) and overall survival (OS) of patients after curative resection of metachronous CRLM. Methods In a retrospective single-centre study, patients after curative resection of metachronous CRLM were included and analysed for DFS and OS with regard to the administration of additive chemotherapy. The Kaplan-Meier method was applied to compare DFS and OS while Cox regression models were used to identify independent prognostic variables. Results Thirty-four of 75 patients were treated with additive 5-FU based chemotherapy. OS was significantly prolonged in this patient subgroup (62 vs 57 months; p = 0.032). Additive chemotherapy significantly improved 10-year survival rates (42% vs 0%, p = 0.023), but not 5-year survival (58% vs 42%, p = 0.24). Multivariate analysis identified additive chemotherapy (p = 0.016, HR 0.44, 95% CI 0.23–0.86), more than five CRLM (p = 0.026, HR 2.46, 95% CI 1.16–10.32) and disease recurrence (0.009, HR 2.70, 95% CI 1.29–5.65) as independent risk factors for OS. Conclusion Additive chemotherapy significantly prolonged OS and 10-year survival in patients after curative resection of metachronous CRLM. Randomized clinical trials are needed in the future to identify optimal chemotherapy regimens for those patients.

Abstract
BACKGROUND Minimally invasive liver surgery is now the standard procedure at experienced centers, whereby the techniques and strategies are continuously evolving. MATERIAL AND METHODS An analysis of English language literature on minimally invasive and robotic liver surgery was performed. The current scientific status was summarized and evaluated on the basis of experience at our own center. RESULTS The advantages of the minimally invasive technique compared to the conventional open technique are shown in liver surgery by improved perioperative results. Concerns about intraoperative complications and possible compromises in oncological radicality have been addressed in a number of publications. First reports on the robot-assisted technique seem to confirm the known advantages of laparoscopic liver surgery. The data available on robot-assisted liver surgery are still limited due to the short period of experience of a few centers and do not yet allow final conclusions; however, an increase in intraoperative safety and an expansion of the surgical spectrum towards highly complex liver resections seems likely. CONCLUSION Even during the learning curve the known advantages of laparoscopic liver surgery seem to be confirmed also for robot-assisted liver surgery. According to the center's own experience, minimally invasive liver surgery will in future be meaningfully supplemented by robotic technology. In particular, technically highly complex resections with reconstruction are made possible.

Abstract
BACKGROUND The separation of conjoined twins is a challenging and rare operation. Recent technological advances in imaging and three-dimensional printing (3DP) have allowed for enhancements in preoperative surgical planning and intraoperative anatomical orientation for complex operations. This report aims to consolidate the current clinical evidence utilizing 3DP models as an effective tool for surgical planning of conjoined twin separation and to detail our surgical approach for complex hepatic separation and management. METHODS A literature review was conducted for conjoined twin separations with preoperative use of 3D models including age at attempted separation, operative outcome, 3D modality, and postoperative course between 1998 and 2020. We also conducted a chart review of our electronic medical record for conjoined twin separations between January 2015 and December 2019. RESULTS We report two cases of conjoined twin separation with preoperative use of 3DP models from our institution: one set in the thoracoomphaloischiopagus orientation and the other set in the thoracoomphalopagus orientation with the presence of intrahepatic vascular anomalies. The literature review produced 10 case reports of conjoined twin separation with use preoperative 3D models accounting for 17 individual separation procedures. We summarize our preoperative radiological planning, the evidence of 3DP models as an educational and preoperative tool, ideal timing for separation, and our surgical approach for complex hepatic separation. CONCLUSIONS Conjoined twin separation requires a multidisciplinary effort to address the multisystem surgical and medical needs of these patients. These complex patients require extensive preoperative imaging for planning separation, and we strongly recommend utilizing 3D printed models when possible for better surgeon understanding of complex variable anatomy. We have found numerous reports of successful conjoined twin separation using 3DP technology in preoperative planning. The use of three-dimensional printed models for preoperative assessments is an invaluable tool and is rapidly improving in fidelity. TYPE OF STUDY Operative technique and case series. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Mexican health system structure allows us to study the differences in bile duct injury (BDI) management. The study aimed to assess the differences in patients with complex BDI in 2 different public sector institutions using a new proposed standard terminology. METHODS Retrospective review (2008-2019) in 2 public institutions (IMSS/SESVER). Bismuth-Strasberg E injuries with hepaticojejunostomy were included. Data are presented in a tabular reporting system. The outcomes were percent of patients attaining primary patency, loss of primary patency, and actuarial primary patency rate. RESULTS Seventy-eight patients (IMSS: n = 37; SESVER: n = 41) without differences in demographic and preoperative assessment were studied. BDI occurred mostly in outside hospitals. Open cholecystectomy was the most common index operation in SESVER (73%, p = 0.02). IMSS had more surgeries (p = 0.007) and repair attempts (p = 0.06) prior to referral. Magnetic resonance cholangiopancreatography was more commonly used in IMSS patients. Biliary stents (45%) and cholangitis (29%) were more common in IMSS (p < 0.05). IMSS patients had longer follow-up than SESVER (p < 0.05). No differences in primary patency rates (IMSS: 89%, SESVER: 97%) and actuarial patency rates were noted. DISCUSSION Despite differences in referral, preoperative, and operative events, good BDI repair outcomes can be achieved. Longer follow-up is needed to monitor these outcomes.

Abstract
INTRODUCTION While several studies have examined the correlation between vitamin D concentrations and post-surgical nosocomial infections, this relationship has yet to be characterized in hepatobiliary surgery patients. We investigated the relationship between serum vitamin D concentration and the incidence of surgical site infection (SSI) in patients in our hepatobiliary surgery unit. METHODS Participants in this observational study were 321 successive patients who underwent the following types of interventions in the hepatobiliary surgery unit of our center over a 1-year period: cholecystectomy, pancreaticoduodenectomy, total pancreatectomy, segmentectomy, hepatectomy, hepaticojejunostomy and exploratory laparotomy. Serum vitamin D levels were measured upon admission and patients were followed up for 1 month. Mean group values were compared using a Student's T-test or Chi-squared test. Statistical analyses were performed using the Student's T-test, the Chi-squared test, or logistic regression models. RESULTS Serum concentrations >33.5 nmol/l reduced the risk of SSI by 50%. Out of the 321 patients analyzed, 25.8% developed SSI, mainly due to organ-cavity infections (incidence, 24.3%). Serum concentrations of over 33.5 nmol/l reduced the risk of SSI by 50%. CONCLUSIONS High serum levels of vitamin D are a protective factor against SSI (OR, 0.99). Our results suggest a direct relationship between serum vitamin D concentrations and SSI, underscoring the need for prospective studies to assess the potential benefits of vitamin D in SSI prevention.

Abstract
Mucinous cystic neoplasms (MCNs) of the pancreas occurring during pregnancy constitute a rare condition requiring special management due to its large size, malignant potential and the risk of fetal growth restriction. The key points to manage MCNs are to perform a correct diagnosis, accurately evaluate the grade of malignant potential in order to establish the right time for pancreatic surgery and to choose the most appropriate fetal mode of delivery. We describe a case of an incidental abdominal mass detected in a third-trimester pregnant woman. At surgery, a huge pancreatic cystic tumour was found and a distal pancreatectomy with splenic preservation was performed. The histopathological analysis revealed an MCN of the pancreas with low-grade dysplasia. To our knowledge, this is the largest pancreatic MCN detected in a pregnant woman reported in the literature and one of the few successfully resected after vaginal delivery.

Abstract
Coronavirus has emerged as a global health threat due to its accelerated geographic spread over the last two decades. This article reviews the current state of knowledge concerning the origin, transmission, diagnosis and management of coronavirus disease 2019 (COVID-19). Historically, it has caused two pandemics: severe acute respiratory syndrome and Middle East respiratory syndrome followed by the present COVID-19 that emerged from China. The virus is believed to be acquired from zoonotic source and spreads through direct and contact transmission. The symptomatic phase manifests with fever, cough and myalgia to severe respiratory failure. The diagnosis is confirmed using reverse transcriptase PCR. Management of COVID-19 is mainly by supportive therapy along with mechanical ventilation in severe cases. Preventive strategies form the major role in reducing the public spread of virus along with successful disease isolation and community containment. Development of a vaccine to eliminate the virus from the host still remains an ongoing challenge.

Abstract
BACKGROUND CCN1 is an extracellular matrix-associated protein thought to be implicated in tumor-stromal interaction in several solid tumors. The aim of our pilot study was to evaluate the correlation between CCN1 expression in stromal cells, pancreatic intraepithelial neoplasia (PanIN) and pancreatic ductal adenocarcinoma cells in resected pancreatic ductal adenocarcinoma (PDAC) specimens, and correlate that clinically. METHODS A total of 42 paraffin-embedded PDAC tumor specimens were stained for CCN1 and evaluated via immunohistochemical (IHC) analysis. Statistical analysis was performed to correlate between CCN1 expression profiles in tumor tissues and clinicopathological parameters of patients. RESULTS Our results showed CCN1 (CYR61) gene was highly expressed in PDAC tissues relative to other organ specific tumor tissues. Also, moderate and overexpression of CCN1 in PanIN was associated with PanIN grade 3 tissues. A statistically significant association was found between PanIN CCN1 scores on one hand and cancer stage, cancer grade, and CCN1 expression among ductal tumor cells and adjacent stromal cells on the other hand. DISCUSSION The associations demonstrated suggest that CCN1 might be contributing to a substantial role in the interaction between the pancreatic tumors on one hand and their surrounding microenvironment and their precursors on the other hand; hence, it might serve as a potential therapeutic target for PDAC.

Abstract
BACKGROUND AND AIM The implications of multi-incision (MILS) and hand-assisted (HALS) laparoscopic techniques for minimally invasive liver surgery with regard to perioperative outcomes are not well defined. The purpose of this study was to compare MILS and HALS using propensity score matching. METHODS 309 patients underwent laparoscopic liver resections (LLR) between January 2013 and June 2018. Perioperative outcomes were analyzed after a 1:1 propensity score match. Subgroup analyses of matched groups, i.e., radical lymphadenectomy (LAD) as well as resections of posterosuperior segments (VII and/or VIII), were performed. RESULTS MILS was used in 187 (65.2%) and HALS in 100 (34.8%) cases, with a significant decrease of HALS resections over time (p = 0.001). There were no significant differences with regard to age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) Score, previous abdominal surgery and cirrhosis between both groups. Patients scheduled for HALS were characterized by a significantly higher rate of malignant tumors (p < 0.001) and major resections (p < 0.001). After propensity score matching (PMS), 70 cases remained in each group and all preoperative variables as well as resection extend were well balanced. A significantly higher rate of radical LAD (p = 0.039) and posterosuperior resections was found in the HALS group (p = 0.021). No significant differences between the matched groups were observed regarding operation time, conversion rate, frequency of major complications, length of intensive care unit (ICU) stay, overall hospital stay and R1 rate. CONCLUSION Our analysis suggests MILS and HALS to be equivalent regarding postoperative outcomes. HALS might be particularly helpful to accomplish complex surgical procedures during earlier stages of the learning curve.
