Abstract
BACKGROUND Despite extensive research in recent decades, pancreatic cancer continues to be among the most lethal forms of cancer, with no substantial increase in survival rates. Local recurrences account for approximately 30 per cent of all disease recurrences. With the intent to improve survival, we designed a novel, hybrid treatment strategy consisting of surgical resection and additional intraoperative electrochemotherapy of the posterior resection surface. We present the study protocols and preliminary findings of a prospective pilot study investigating this treatment approach. METHODS Consenting patients with resectable pancreatic head ductal adenocarcinoma who met the inclusion criteria were enrolled in the study. After surgical resection, electrochemotherapy with bleomycin was performed using plate electrodes to cover the area between anatomical landmarks. RESULTS Electrochemotherapy of the posterior resection surface was feasible in all 7 patients. We observed pancreatic fistula grade B in only one patient; all other noted complications were Clavien-Dindo grade 2 or less. The hospital mortality was 0%. CONCLUSIONS Our preliminary results suggest that a hybrid approach combining surgery with intraoperative electrochemotherapy is safe and feasible.

Abstract
Splanchnic vein thrombosis (SVT), a thrombosis which involves the portal, mesenteric, and splenic veins, and the Budd-Chiari syndrome, represents an uncommon type of venous thromboembolism (VTE). Like with deep vein thrombosis of the lower extremities and pulmonary embolism, ample evidence suggests a significant association between SVT and cancer, particularly intra-abdominal solid malignancies (e.g. hepatobiliary and pancreatic cancers) and myeloproliferative neoplasms (MPN). Clinical symptoms of SVT in cancer patients can be ambiguous, and frequently attributed to the primary cancer itself. Alternatively, SVT may be asymptomatic and detected incidentally during cancer staging or follow-up evaluations. SVT can also precede the diagnosis of cancer and has been associated with poorer outcomes in patients with liver or pancreatic cancers. Therefore, an unprovoked SVT warrants a thorough evaluation for an underlying malignancy or MPN. Cancer-associated SVT carries a high risk of VTE extension, recurrence and bleeding. Extended anticoagulant treatment is often required in the absence of a high bleeding risk. Guidelines suggest treatment with either low molecular weight heparin (LMWH) or direct oral anticoagulants (DOACs), although available data on the safety and effectiveness of DOACs in these patients is limited. This comprehensive review outlines the epidemiology, pathogenesis, risk factors, and diagnosis of cancer-associated SVT and underscores the importance of comprehensive patient evaluation and evidence-based management.

Abstract
BACKGROUND The primary aim of the present study was to explore risk factors for portal vein system thrombosis following splenectomy. METHODS A systematic search of PubMed, Embase and Cochrane libraries was conducted to identify original studies that fulfilled the inclusion criteria. Raw data on potential risk factors for portal vein system thrombosis after splenectomy were extracted for meta-analysis. Subsequently, a sensitivity analysis was conducted to verify the stability of the results. RESULTS Eighteen studies with 626 thrombosis events from 1807 splenectomy met the inclusion criteria. Larger spleen volume (SMD 0.44, P = 0.000), broader splenic vein diameter (WMD 2.30, P = 0.000), broader portal vein diameter (WMD 2.08, P = 0.000), a lower velocity of portal blood flow (WMD -0.91, P = 0.001), decreased platelet count (WMD -5.14, P = 0.007), decreased white blood cell (WMD -0.40, P = 0.027), decreased haemoglobin (WMD -9.14, P = 0.002), ascites (OR 1.81, P = 0.003) and bleeding history before surgery (OR 1.88, P = 0.002) were identified to be factors that exacerbated the risk of portal vein system thrombosis after splenectomy. Sex, age, preoperative prothrombin time, postoperative platelet count, postoperative D-dimer, operation time and intraoperative blood loss, did not increase the risk of thrombosis. CONCLUSION Larger spleen volume, broader splenic vein diameter, broader portal vein diameter, a lower velocity of portal blood flow, ascites, bleeding history before surgery, decreased platelet count, white blood cell and haemoglobin may increase the risk of portal vein system thrombosis.

Abstract
BACKGROUND Portal vein system thrombosis (PVST) is a common postoperative complication brought by laparoscopic splenectomy and pericardial disconnection (LSD) among patients who suffered from portal hypertension and hypersplenism. This research lies mainly in probing into the risk factors of PVST and evaluating the effects of warfarin on PVST prevention. MATERIALS AND METHODS We took 131 individuals who have carried out LSD from January 2015 to January 2021. Patients were divided into warfarin group (n = 68) and aspirin group (n = 63). Meanwhile, thrombosis factors were analyzed in PVST arm (n = 48) and non-PVST arm (n = 83). RESULTS We analyzed the early postoperative anticoagulation effect, 20 patients (29.4%) in the warfarin group developed PVST, and 28 patients (44.4%) in the aspirin group. The chance to PVST during the first year after operation was lower in the warfarin group than in the aspirin group (F = 13.43, P = 0.006). Risk factors for PVST were analyzed, and diabetes, the diameter of the portal vein and splenic vein, and the velocity of portal blood flow were statistically significant between the PVST arm and non-PVST arm (P < < 0.05). Multiple logistic regression analyses have shown that diabetes, portal vein diameter, splenic vein diameter, and the velocity of portal blood flow were the risk factors of PVST. CONCLUSIONS The portal vein diameter, splenic vein diameter, portal vein flow velocity, and diabetes are risk factors for the PVST after LSD. The prophylactic use of warfarin anticoagulation markedly decreases the probability of occurrence of the PVST in patients with portal hypertension after LSD compared to aspirin.

Abstract
Pancreatic surgery still remains burdened by high levels of morbidity and mortality with a relevant incidence of complications, even in high volume centers. This review highlights the interventional radiological management of complications after pancreatic surgery. The current literature regarding the percutaneous drainage of fluid collections due to pancreatic fistulas, percutaneous transhepatic biliary drainage due to biliary leaks and transcatheter embolization (or stent–graft) due to arterial bleeding is analyzed. Moreover, also, percutaneous intra-portal islet auto-transplantation for the prevention of pancreatogenic diabetes in case of extended pancreatic resection is also examined. Moreover, a topic not usually treated in other similar reviewsas percutaneous intra-portal islet auto-transplantation for the prevention of pancreatogenic diabetes in case of extended pancreatic resection is also one of our areas of focus. In islet auto-transplantation, the patient is simultaneously donor and recipient. Differently from islet allo-transplantation, it does not require immunosuppression, has no risk of rejection and is usually efficient with a small number of transplanted islets.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is a condition caused by hemodynamic disorders. It may be noted in the portal vein system when there is an inflammatory stimulus in the abdominal cavity. However, PVT is rarely reported after hepatectomy. At present, related guidelines and major expert opinions tend to consider vitamin K antagonists or low-molecular weight heparin (LMWH) as the standard treatment. But based on research, direct oral anticoagulants may be more effective and safe for noncirrhotic PVT and are also beneficial by reducing the recurrence rate of PVT.
CASE SUMMARY A 51-year-old woman without any history of disease felt discomfort in her right upper abdomen for 20 d, with worsening for 7 d. Contrast-enhanced computed tomography (CECT) of the upper abdomen showed right liver intrahepatic cholangiocarcinoma with multiple intrahepatic metastases but not to the left liver. Therefore, she underwent right hepatic and caudate lobectomy. One week after surgery, the patient underwent a CECT scan, due to nausea, vomiting, and abdominal distension. Thrombosis in the left branch and main trunk of the portal vein and near the confluence of the splenic vein was found. After using LMWH for 22 d, CECT showed no filling defect in the portal vein system.
CONCLUSION Although PVT after hepatectomy is rare, it needs to be prevented during the perioperative period.

Abstract
BACKGROUND Right hepatectomy occasionally requires portal vein resection (PVR) and causes postoperative portal vein thrombosis (PVT). METHODS A total of 247 patients who underwent right hepatectomy were evaluated using a three-dimensional analyzer to identify the morphologic changes in the portal vein (PV). The patients' characteristics were compared between the PVR group (n = 73) and non-PVR group (n = 174), and risk factors for PVT were investigated. The PVR group were subdivided into the wedge resection (WR) group (n = 38) and segmental resection (SR) group (n= 35). RESULTS Postoperative PVT occurred in 20 patients (8.1%). Multivariate analyses in all patients revealed that postoperative left PV diameter/main PV diameter (L/M ratio) <0.56 (odds ratio [OR] 4.00, p = 0.009) and PVR (OR 3.31, p = 0.031) were significant risk factors for PVT. In 73 patients who underwent PVR, PVT occurred in 14 (19%) and WR (OR 11.5, p = 0.005) and L/M ratio <0.56 (OR 5.51, p = 0.016) were significant risk factors for PVT. CONCLUSION PVR was one of the significant risk factors for PVT after right hepatectomy. SR rather than WR may be recommended for preventing PVT.

Abstract
Objective Splenectomy is one crucial solution for hypersplenism with portal hypertension. However, portal vein system thrombosis (PVST) caused by hemodynamic changes affects the prognosis of patients. We analyze the changes in portal vein hemodynamics following splenectomy for Wilson’s disease combined with portal hypertension and the influencing factors that lead to PVST. Methods A retrospective cohort study was conducted, in which 237 Wilson’s disease patients with hypersplenism underwent splenectomy. The hemodynamic indices of the portal vein were monitored before surgery and on the 1st, 7th, and 14th days around surgery. The patients were divided into PVST and non-PVST groups. The clinical factors were identified by univariate and multivariate logistic regression. The Logit P was calculated according to the logistic regression prediction model, and the ROC curve for each independent factor was plotted. Results The portal vein velocity, flow, and inner diameter showed a downward trend around surgery, with statistically significant differences between each time point (P < 0.01). The PVST incidence rate was 55.7%. Univariate analysis revealed that the platelet (PLT) levels on the postoperative 3rd and 7th days (P = 0.001; P < 0.001), D-dimer (D-D) on the postoperative 7th and 14th days (P = 0.002; P < 0.001), preoperative portal vein velocity, flow, diameter (P < 0.001), and splenic vein diameter (P < 0.001) were all statistically and significantly different between the two groups. Multivariate logistic regression revealed a significant increase in PLT on the postoperative 7th day (OR = 1.043, 95% CI, 1.027–1.060, P < 0.001) and D-D on the postoperative 14th day (OR = 1.846, 95% CI, 1.400–2.435, P < 0.001). Preoperative portal and splenic vein diameters (OR = 1.565, 95% CI, 1.213–2.019, P = 0.001; OR = 1.671, 95% CI, 1.305–2.140, P < 0.001) were the risk factors for PVST. However, preoperative portal vein velocity and flow (OR = 0.578, 95% CI, 0.409–0.818, P = 0.002; OR = 0.987, 95% CI, 0.975–0.990, P = 0.046) were protective factors for PVST. Logit P was calculated using a logistic regression prediction model with a cut-off value of −0.32 and an area under receiver operating characteristic curve of 0.952 with 88.61% accuracy. Conclusions Splenectomy relieves portal hypertension by reducing the hemodynamics index. PVST is linked to multiple factors, including preoperative portal vein diameter, velocity, flow, and splenic vein diameter, especially PLT on the postoperative 7th day and D-D on the postoperative 14th day. The predictive model is accurate in predicting PVST.

Splenic volume and splenic vein diameter are independent pre-operative risk factors of portal vein thrombosis after splenectomy: a retrospective cohort study. BMC Surg 2021; 21:366. [PMID: 34641842 PMCID: PMC8513289 DOI: 10.1186/s12893-021-01364-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Accepted: 09/23/2021] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Portal vein thrombosis (PVT) is a common complication following splenectomy. It affects between 5 and 55% of patients undergoing surgery with no clearly defined pre-operative risk factors. The aim of this study was to determine the pre-operative risk factors of PVT. PATIENTS AND METHOD Single centre, retrospective study of data compiled for every consecutive patient who underwent splenectomy at Toulouse University Hospital between January 2009 and January 2019. Patients with pre- and post-surgical CT scans have been included. RESULTS 149 out of 261 patients were enrolled in the study (59% were males, mean age 52 years). The indications for splenectomy were splenic trauma (30.9%), malignant haemopathy (26.8%) and immune thrombocytopenia (8.0%). Twenty-nine cases of PVT (19.5%) were diagnosed based on a post-operative CT scan performed on post-operative day (POD) 5. Univariate analysis identifies three main risk factors associated with post-operative PVT: estimated splenic weight exceeding 500 g with an OR of 8.72 95% CI (3.3-22.9), splenic vein diameter over 10 mm with an OR of 4.92 95% CI (2.1-11.8) and lymphoma with an OR of 7.39 (2.7-20.1). The role of splenic vein diameter with an OR of 3.03 95% CI (1.1-8.6), and splenic weight with an OR of 5.22 (1.8-15.2), as independent risk factors is confirmed by multivariate analysis. A screening test based on a POD 5 CT scan with one or two of these items present could indicate sensitivity of 86.2% and specificity of 86.7%. CONCLUSION This study suggests that pre-operative CT scan findings could predict post-operative PVT. A CT scan should be performed on POD 5 if a risk factor has been identified prior to surgery.

Abstract
Background Portal vein system thrombosis (PVST) is a common and serious complication after splenectomy. Key factors, including wider diameters of the portal vein, decreased liver function, and high flow volume of portosystemic collateral vessel, are recognized PVST risks. Relationships between PVST and altered hemorheology, including increased plasma viscosity, remain unclear. We investigated hemorheological alterations and explored risk factors of PVST in patients with cirrhosis after splenectomy. Material/Methods Data on patients with cirrhosis who underwent splenectomy were collected retrospectively from January 2018 to June 2020. Color Doppler ultrasonography was performed after splenectomy. Hemorheological indexes were compared between groups. Receiver operating characteristic (ROC) analysis was conducted to analyze risk factor cutoff values. Univariate and multivariate analyses were conducted to explore risk factors of PVST. Results A total of 50 patients were divided into a PVST group (n=30) and control group (n=20). Hemorheological indexes of activated partial thromboplastin time, fibrinogen degradation products (FDP), D-dimer, middle shear rates 50 and 30, low shear rates 5 and 1, and hematocrit in the PVST group were significantly higher than those of the control group (P<0.05). FDP and low shear rate 1 were found to be risk factors of PVST after splenectomy by multivariate analysis. ROC analysis showed that the cutoff points for FDP and low shear rate 1 were ≥38.6 ug/mL and ≥16.855 mPa.s, respectively. Conclusions PVST after splenectomy is closely related to hemorheological alteration. FDP and low shear rate 1 may be valuable markers of PVST.

Abstract
Splanchnic vein thrombosis (SVT), which includes portal, mesenteric, and splenic vein thrombosis and the Budd-Chiari syndrome, is an infrequent manifestation of venous thromboembolism (VTE). Like typical site VTE, SVT is also frequently associated with cancer, particularly intra-abdominal solid malignancies and myeloproliferative neoplasms (MPNs). The clinical presentation of SVT is nonspecific. Symptoms may be related to the underlying malignancy, and thrombosis is incidentally diagnosed by imaging studies for cancer staging or follow-up in a substantial proportion of cases. The occurrence of SVT predicts worse prognosis in patients with liver or pancreatic cancer and, not uncommonly, SVT may precede the diagnosis of cancer. Therefore, the occurrence of an apparently unprovoked SVT should prompt careful patient evaluation for the presence of an underlying malignancy or MPN. Cancer patients carry a high risk of VTE extension and recurrence and long-term anticoagulant treatment is suggested in the absence of high risk of bleeding. Either LMWH or direct oral anticoagulants (DOACs) are suggested for the treatment of patients with cancer-related SVT, although limited experience is available on the use of DOACs in these settings. Vitamin K antagonists (VKAs) are suggested for the short and long-term treatment of SVT associated with MPN. This review outlines the epidemiological aspects, pathogenesis, risk factors, and diagnosis of cancer-associated SVT, and addresses questions regarding the management of this challenging condition.

Abstract
Background The aim of this study was to establish and validate an easy-to-use nomogram to predict portal vein thrombosis (PVT) in patients with cirrhosis after splenectomy and to test its predictive ability. Material/Methods This retrospective study included 315 patients with cirrhosis who underwent splenectomy at 2 high-volume medical centers. The least absolute shrinkage and selection operator (LASSO) regression method was used to select the predictors in the training cohort, and multivariable logistic regression analysis was performed to establish the predictive nomogram model. We determined the prediction value of the nomogram by the area under the receiver operating characteristic curve (AUROC), the calibration curve, and decision curve analysis. Finally, the applicability of the nomogram was internally and independently validated. Results The predictors of PVT included portal vein diameter, splenic vein diameter, body mass index, and platelet count. Based on the clinical and radiomic models, the nomogram had good predictive efficiency for predicting PVT in patients with cirrhosis after splenectomy, with an AUROC of 0.887 (0.856 in internal validation and 0.796 in independent validation). The decision curve analysis revealed that the nomogram had good clinical application value. Conclusions We successfully developed an easy-to-use nomogram to predict the probability of PVT in patients with cirrhosis after splenectomy. The nomogram can help clinicians make timely, individualized clinical decisions for PVT in patients with cirrhosis after splenectomy.

Influences of Anatomorphological Features of the Portal Venous System on Postsplenectomy Hemodynamic Characteristics in Patients With Portal Hypertension: A Computational Model-Based Study.

Abstract
Splenectomy, as an effective surgery for relieving complications caused by portal hypertension, is often accompanied by a significantly increased incidence of postoperative thrombosis in the portal venous system (PVS). While the underlying mechanisms remain insufficiently understood, the marked changes in hemodynamic conditions in the PVS following splenectomy have been suggested to be a potential contributing factor. The aim of this study was to investigate the influences of the anatomorphological features of the PVS on hemodynamic characteristics before and after splenectomy, with emphasis on identifying the specific anatomorphological features that make postoperative hemodynamic conditions more clot-promoting. For this purpose, idealized computational hemodynamics models of the PVS were constructed based on general anatomical structures and population-averaged geometrical parameters of the PVS. In the models, we incorporated various anatomorphological variations to represent inter-patient variability. The analyses of hemodynamic data were focused on the spatial distribution of wall shear stress (WSS) and the area ratio of wall regions exposed to low WSS (ALS). Obtained results showed that preoperative hemodynamic conditions were comparable among different models in terms of space-averaged WSS and ALS (all were small) irrespective of the considerable differences in spatial distribution of WSS, whereas, the inter-model differences in ALS were significantly augmented after splenectomy, with the value of ALS reaching up to over 30% in some models, while being smaller than 15% in some other models. Postoperative ALS was mainly determined by the anatomical structure of the PVS, followed by some morphogeometrical parameters, such as the diameter and curvature of the splenic vein, and the distance between the inferior mesenteric vein and splenoportal junction. Relatively, the angles between tributary veins and trunk veins only had mild influences on ALS. In addition, a marked increase in blood viscosity was predicted after splenectomy, especially in regions with low WSS, which may play an additive role to low WSS in initiating thrombosis. These findings suggest that the anatomical structure and some morphogeometrical features of the PVS are important determinants of hemodynamic conditions following splenectomy, which may provide useful clues to assessing the risk of postsplenectomy thrombosis based on medical imaging data.

Abstract
Portal vein thrombosis (PVT) is the most frequent among the splanchnic vein thrombosis, accounting for 90% of cases. More than half of PVT are provoked by liver cirrhosis, solid cancer or myeloproliferative neoplasms. The remaining cases are non-malignant non-cirrhotic PVT and include either unprovoked events or thrombosis secondary to other less common risk factors (e.g. abdominal surgery, intrabdominal inflammations/infections, or hormonal stimuli). Anticoagulant therapy in patients with acute symptomatic PVT should be started early after diagnosis, if no active bleeding, to obtain greater vessel recanalization and reduce the occurrence of portal-hypertension related complications. Gastroesophageal varices do not represent a contraindication to anticoagulant treatment, as long as adequate measures have been undertaken for the prophylaxis of gastroesophageal bleeding. Different treatment options (unfractionated or low molecular weight heparin, vitamin K antagonists and direct oral anticoagulants [DOACs]) can be considered. In this narrative review we will discuss the treatment of PVT in the three most common scenarios (cirrhosis-associated, cancer-associated and non-malignant non-cirrhotic PVT). We will also discuss the role of the DOACs and summarise recent guidelines on this topic.

Abstract
This study aimed to evaluate the safety and efficacy of rivaroxaban in preventing portal vein system thrombosis (PVST) in patients with liver cirrhosis after splenectomy and pericardial devascularization. 70 cirrhotic patients undergoing splenectomy and pericardial devascularization were randomly assigned to rivaroxaban treatment (n=35) or low-molecular weight heparin (LMWH) plus warfarin treatment (n=35) for 30 days in this randomized controlled trial. The primary endpoint is the PVST formation. Ultrasound doctors and radiologists were blinded to the randomization results. Both groups received routine outpatient inspection every month and were followed for one year. 17 patients (48.6 %) in rivaroxaban group developed PVST, compared with 27 patients (77.1 %) in LMWH plus warfarin group (P=0.025). The incidence of PVST during the first year postoperation was significantly lower in rivaroxaban group than in LMWH plus warfarin group (F=7.901, P=0.006). The intra-group comparisons versus baseline showed the liver function improved from POD 21 to POM 1, and coagulation function improved from POM 2, in rivaroxaban group. In contrast, the liver function improved from POM 1 to POM 2, and coagulation function improved from POM 4, in LMWH plus warfarin group. The prophylactic use of rivaroxaban significantly decreases the incidence of PVST after splenectomy and pericardial devascularization in cirrhotic patients compared to LMWH plus warfarin treatment. Besides, rivaroxaban treatment was safe and effective and associated with better liver and coagulation functions improvement than LMWH plus warfarin treatment.

Abstract
Portal vein system thrombosis (PVST) is a form of venous thrombosis, which behaves as a common and potentially life-threatening complication after splenectomy. Numerous studies have been made to investigate the mechanism and the risk factors of PVST. However, the research on the prevention and treatment of PVST associated with platelet's (PLT) rule of change is rare. This work mainly investigates the PLT's rule of change and its correlativity with the formation of PVST after splenectomy. The retrospective study included 117 patients who underwent splenectomy from August 2014 to June 2018 and monitored by blood routine, D-dimer (D-D), and portal vein system ultrasound routinely after splenectomy. The changes of PLT and D-D were recorded and compared before and after each operation. We analyzed the changes of PLTand D-D as well as the incidence of PVST postoperatively. Most of the patients’ PLT increased significantly after splenectomy. On the first day after operation, there were 80 patients’ (68.38%) PLTrecovered to normal or above normal. The proportion of patients with abnormally high PLT value on the seventh and fourteenth day were 60.68 per cent and 81.20 per cent, respectively. Thereinto, there were 67 patients’ (57.26%) PLT beyond 500 x 109/L on the 14th day. The D-D of all patients exceeded the normal range on the first, seventh, and fourteenth day after operation, and the difference was statistically significant ( P < 0.05), which behaved similar like PLT. Meanwhile, our color Doppler ultrasonography showed that the incidence of PVST was 70.79 per cent. Among the patients with PVST, 82 (100%) patients’ PLT was increased after operation. The PLT of patients increased obviously after splenectomy. The increased blood viscosity caused by the consecutive elevation of PLT may result in a higher PVST incidence. Early intervention and treatment are needed clinically for PVST after splenectomy.

Computed tomography-based score model/nomogram for predicting technical and midterm outcomes in transjugular intrahepatic portosystemic shunt treatment for symptomatic portal cavernoma. World J Clin Cases 2020; 8:887-899. [PMID: 32190625 PMCID: PMC7062625 DOI: 10.12998/wjcc.v8.i5.887] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 01/19/2020] [Accepted: 02/11/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) may be technically difficult in patients with cavernous transformation of the portal vein (CTPV). Computed tomography (CT) is widely used for assessing the situation of the portal vein and its tributaries before TIPS, and an ultrasound-based Yerdel grading system has been developed, which is deemed useful for liver transplantation. Therefore, we hypothesized that a CT-based CTPV scoring system could be useful for predicting technical and midterm outcomes in TIPS treatment for symptomatic portal cavernoma.
AIM To investigate the clinical significance of a CT-based score model/nomogram for predicting technical success and midterm outcome in TIPS treatment for symptomatic CTPV.
METHODS Patients with symptomatic CTPV who had undergone TIPS from January 2010 to June 2017 were retrospectively analysed. The CTPV was graded with a score of 1-4 based on contrast-CT imaging findings of the diseased vessel. Outcome measures were technical success rate, stent patency rate, and midterm survival. Cohen’s kappa statistic, the Kaplan-Meier and log-rank tests, and uni- and multivariable analyses were performed. A nomogram was constructed and verified by calibration and decision curve analysis.
RESULTS A total of 76 patients (45 men and 31 women; mean age, 52.3 ± 14.7 years) were enrolled in the study. The inter-reader agreement (κ) of the CTPV score was 0.81. TIPS was successfully placed in 78% of patients (59/76). The independent predictor of technical success was CTPV score (odds ratio [OR] = 5.56, 95% confidence interval [CI]: 3.55-9.67, P = 0.002). The independent predictors of primary TIPS patency were CTPV score and splenectomy (OR = 9.22, 95%CI: 4.78-13.45, P = 0.009; OR = 4.67, 95%CI: 2.59-7.44, P = 0.017). The survival rates differed significantly between the TIPS success and failure groups. The clinical nomogram was made up of patient age, model for end-stage liver disease score, and CTPV score. The calibration curves and decision curve analysis verified the usefulness of the CTPV score-based nomogram for clinical practice.
CONCLUSION TIPS should be considered a safe and feasible therapy for patients with symptomatic CTPV. Furthermore, the CT-based score model/nomogram might aid interventional radiologists in therapeutic decision-making.

Abstract
Few cases of portal vein thrombosis secondary to gastric cancer surgery have been reported. Here we report the diagnosis and management of two such cases. Case 1: Gastric carcinoma with acute hematemesis was detected by endoscopy in the gastric body of a 48-year-old woman. Histologic examination revealed signet-ring cell carcinoma with marked invasion of the vessels and nerves. Laparoscopic partial gastrectomy and Roux-en-Y gastrogastrostomy were performed. One month after surgery, imaging examination showed the formation of thrombi in the main portal vein and the right hepatic vein. Case 2: Gastric carcinoma with pyloric obstruction was clinically diagnosed in a 66-year-old woman. Laparoscopic partial gastrectomy and Billroth Roux-en-Y gastrogastrostomy were again performed. Two months after surgery, an abdominal imaging examination detected a thrombus in the right hepatic vein. Clinicians should consider portal vein thrombosis in patients with hyperthermia combined with an abnormal increase in procalcitonin.

Abstract
PURPOSE To evaluate the significance of parenchymal, hilar and capsular involvement of the spleen with regard to survival. METHODS All patients who underwent primary cytoreductive surgery for advanced ovarian-tubal-peritoneal (OTP) epithelial cancer were reviewed retrospectively. Stage 3C patients who had an upper abdomen involvement and who were optimally debulked were included. Patients who had abdomen-confined disease, but were upstaged to stage 4B due to splenic parenchymal metastases were also included. RESULTS Seventy four patients eligible with the inclusion criteria who underwent splenectomy and 69 patients who did not undergo splenectomy were included. The median follow-up time was 39.1 months. The median overall survival of the study group was 61.4 months. Patients who underwent splenectomy were grouped according to the involved site of the spleen: parenchyma subgroup, hilus subgroup, capsule subgroup and benign subgroup. The median overall survival of patients in the hilus subgroup was 41.1 months. The median overall survival of patients who were not in the hilus subgroup was 65.5 months. Patients in the hilus subgroup showed significantly shorter survival (p = 0.035). Hilus subgroup was associated with a statistically significant increase in mortality risk (hazard ratio 1.971; 95% confidence interval 1.1-3.531). CONCLUSIONS Splenic hilus involvement predicts poorer survival outcomes among stage 3C epithelial OTP cancer patients with disease expansion to upper abdomen. According to current study and many published studies, hilar involvement had a higher incidence rate compared to parenchymal involvement. Thus, hilar involvement would be a beneficial clinical predictor of survival for larger number of patients.

World J Clin Cases 2019; 7:2450-2462. [PMID: 31559281 PMCID: PMC6745325 DOI: 10.12998/wjcc.v7.i17.2450] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2019] [Revised: 07/11/2019] [Accepted: 07/20/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) is widely accepted as an alternative to surgery for management of complications of portal hypertension. TIPS has been used to treat portal vein thrombosis (PVT) in many centers since the 1990s. Although TIPS has good therapeutic effects on the formation of PVT, the effect of PVT on TIPS stenting has rarely been reported. Patients with splenectomy and pericardial devascu-larization have a high incidence of PVT, which can markedly affect TIPS stent patency and increase the risk of recurrent symptoms associated with shunt stenosis or occlusion.
AIM To investigate the incidence of PVT after splenectomy and its influence on the patency rate of TIPS in patients with cirrhosis and portal hypertension.
METHODS Four hundred and eighty-six patients with portal hypertension for refractory ascites and/or variceal bleeding who required TIPS placement between January 2010 and January 2016 were included in this retrospective analysis. Patients without prior splenectomy were defined as group A (n = 289) and those with prior splenectomy as group B (n = 197). The incidence of PVT before TIPS was compared between the two groups. After TIPS placement, primary patency rate was compared using Kaplan–Meier analysis at 3, 6, 9 and 12 mo, and 2 and 3 years. The clinical outcomes were analyzed.
RESULTS Before TIPS procedure, the incidence of PVT in group A was lower than in group B (P = 0.003), and TIPS technical success rate in group A was higher than in group B (P = 0.016). The primary patency rate in group A tended to be higher than in group B at 3, 6, 9 and 12 mo, 2 years and 3 years (P = 0.006, P = 0.011, P = 0.023, P = 0.032, P = 0.037 and P = 0.028, respectively). Recurrence of bleeding and ascites rate in group A was lower than in group B at 3 mo (P ≤ 0.001 and P = 0.001), 6 mo (P = 0.003 and P = 0.005), 9 mo (P = 0.005 and P = 0.012), 12 mo (P = 0.008 and P = 0.024), 2 years (P = 0.011 and P = 0.018) and 3 years (P = 0.016 and P = 0.017), respectively. During 3-years follow-up, the 1-, 2- and 3-year survival rate in group A were higher than in group B (P = 0.008, P = 0.021, P = 0.018, respectively), but there was no difference of the incidence of hepatic encephalopathy (P = 0.527).
CONCLUSION Patients with prior splenectomy have a high incidence of PVT, which potentially increases the risk of recurrent symptoms associated with shunt stenosis or occlusion.

Ann Hepatobiliary Pancreat Surg 2018; 22:116-127. [PMID: 29896572 PMCID: PMC5981141 DOI: 10.14701/ahbps.2018.22.2.116] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2017] [Revised: 12/08/2017] [Accepted: 12/10/2017] [Indexed: 02/06/2023] Open
Abstract
Backgrounds/Aims Partial splenectomy (PS) is a surgical option for splenic mass, in order to reduce postoperative complications and preserve the splenic function. Despite this, data in literature is still scarce. The present study aimed to reveal our recent experience and provide a comprehensive overview of the feasibility and complications related to various surgical approaches. Methods Data of patients who underwent PS, between 2014 and 2017 were retrospectively reviewed. Literature was searched for studies reporting all types of PS in adult or adolescent patients. Results Five PS were performed in our department: two (40%) by laparoscopy and three (60%) by laparotomy. Two (40%) postoperative complications were detected, and in one of them, total splenectomy (TS) by laparotomy was finally required. There were no deaths or complications at last follow-up. Twenty studies including 213 patients were identified in the literature search. The rate of conversion from laparoscopic to open surgery was 3% (range, 5–50%) and in 3% of cases (range, 7–10%) PS was converted into total TS and the overall morbidity rate was 8% (range, 5–25%). In comparison to laparotomy, the conversion rate of laparoscopic approach to TS was 3.5% (vs. 1.4%) and a morbidity rate of 9.8% (vs. 4.3%). Conclusions The present review shows that PS is a viable procedure in selected cases. The mini-invasive approach seemed to be feasible despite the presence of higher rate of complications than the open technique. In future, further studies on this topic are needed by involving more patients. Furthermore, it is proposed that the development of robotic surgery could make this approach the new gold-standard technique for spleen-preserving surgery.
