BACKGROUND/AIM The aim of this study was to investigate the risk factors of surgical site infection (SSI) in patients who underwent liver resection for colorectal liver metastases (CRLM). PATIENTS AND METHODS A total of 151 patients who underwent liver resection for CRLM were included in this study. We investigated the relationship between the patient characteristics and perioperative factors and the incidence of SSI. RESULTS Nineteen (13%) of these patients developed SSI. Multivariate analysis revealed that modified Glasgow Prognostic Score (mGPS) (1 or 2, odds ratio 3.86, p=0.03) and presence of an enterostomy (yes, odds ratio 3.93, p=0.04) were significant and independent risk factors for SSI. CONCLUSION A higher mGPS and an enterostomy were risk factors for SSI in patients who underwent a liver resection for CRLM.

Nutritional status assessment is essential in cancer patients because a poor nutritional status has been associated with poor outcomes; however, the impact of rapid turnover proteins (RTPs), such as prealbumin, transferrin, and retinol-binding protein, on the outcomes of hepatocellular carcinoma (HCC) has not been well-investigated. We therefore examined the prognostic significance of RTPs in patients with HCC after curative resection. This study included 150 patients who underwent elective hepatic resection for HCC between January 2011 and December 2018. The prealbumin, transferrin, and retinol-binding protein levels were classified into two groups (high vs. low); the RTP score (0–3) was calculated as the sum of each RTP measurement (high = 0; low = 1). We retrospectively investigated the relationship between the RTP score and disease-free and overall survival. Multivariate analysis showed that a high RTP score (P = 0.022), presence of sarcopenia (P = 0.001), and stage III or higher (P = 0.005) were independent predictors of disease-free survival, while a high RTP score (P

Aim The prognostic impact of postoperative systemic inflammatory response using an intra/post‐operative prognostic scoring system in patients with colorectal liver metastases (CRLM) after hepatic resection had never been investigated previously. Methods In total, 149 patients who underwent hepatic resection for CRLM were analyzed retrospectively. Intra/post‐operative prognostic scoring was performed using the postoperative modified Glasgow Prognostic Score (mGPS) at the first visit, after discharge, or a month after surgery during hospitalization. We investigated the association between clinicopathologic variables and disease‐free survival or overall survival by univariate and multivariate analyses. Results The median evaluation period of postoperative mGPS was 30 (26‐36) days after hepatectomy. Seventy‐one patients (48%) were classified as postoperative day 30 mGPS 1 or 2. In multivariate analysis, an extrahepatic lesion (P = .02), multiple tumors (P = .05), and postoperative day 30 mGPS 1 or 2 (P, In the present study, we demonstrated that postoperative systemic inflammatory response represented by postoperative day 30 modified Glasgow Prognostic Score (mGPS) was independently associated with poor disease‐free and overall survival rates after hepatic resection for colorectal liver metastases (CRLM). Furthermore, postoperative day 30 mGPS was associated with advanced CRLM, invasive surgery, and infectious postoperative complications.

Introduction The aim of this study is to investigate the relationship between preoperative serum transferrin level and long-term outcomes in patients with colorectal liver metastases after hepatic resection. Methods We retrospectively investigated 72 patients who underwent hepatic resection for colorectal liver metastases and explored the relationship between serum transferrin level and long-term outcomes. Results In multivariate analysis, H3 (odds ratio 3.43, 95% confidence interval 1.11–10.89 and P = 0.03) was an independent and significant predictor of the disease-free survival, and a transferrin level ≥ 190 mg/dl (odds ratio 0.20, 95% confidence interval 0.05–0.79 and P = 0.02) and the time to recurrence after hepatectomy Conclusions The serum transferrin level is a useful predictor of poor overall survival in patients with colorectal liver metastases after hepatic reaction.

Several kinds of systemic inflammatory response, classified into two types: C-reactive protein (CRP)-based type and blood cell count-based type, were reported as a prognostic indicator in patients with pancreatic cancer (PC). However, there is no consensus which types is more sensitive predictor in patients with PC. Therefore, we here developed a novel biomarker, C-NLR, which consists of both CRP and neutrophil-to-lymphocyte ratio (NLR), and we evaluated the prognostic significance of C-NLR in patients with PC after pancreatic resection. A total of 217 patients was comprised in this study. We retrospectively investigated the relation between C-NLR and disease-free survival (DFS) and overall survival (OS) after pancreatic resection. Optimal cutoff level of C-NLR was defined as 0.206 by a ROC analysis. By multivariate analysis, age (P = 0.024), TNM stage (P

Background Although indications of laparoscopic hepatectomy have been expanded, the laparoscopic approach after right hepatic lobectomy has a very high burden. The purpose of this study was to evaluate patients undergoing laparoscopic repeat hepatectomy for recurrent hepatic tumors after open right lobectomy. Patients and methods Five cases of laparoscopic repeat hepatectomy for recurrent hepatic tumors after open right lobectomy were included in the study. Results All the tumors in segment 3 were intraoperatively detected and curatively resected by partial hepatectomy. The tumors in segment 2 could not be detected intraoperatively due to hypertrophic liver deformity and adhesion. They were curatively resected by anatomical subsegmental approach. Conclusion For recurrent tumors located in segment 2 after right lobectomy, anatomical subsegmental approach should be preferred, not only from an oncological standpoint, but also for securing curative laparoscopic resection and overcoming anatomical difficulties.

Background Pancreatic cancer is one of the most aggressive digestive cancers. The tumor expression of thrombomodulin (TM) is correlated with favorable prognosis in several types of cancer. However, this correlation has not been confirmed in hepato‐pancreato‐biliary cancer. The aim of this study was to evaluate the prognostic value of TM expression in resected pancreatic ductal adenocarcinoma. Methods The data of patients who underwent pancreatic resection for pancreatic invasive ductal adenocarcinoma were obtained from a prospectively maintained database. A total of 131 patients were included. Paraffin sections of tumor tissues were stained immunohistochemically using TM antibody. The patients were divided into two groups: the TM‐positive or TM‐negative group. Results The specimens were TM‐positive in 72 cases. TM expression was a significant factor of favorable prognosis in univariate analysis for disease‐free (DFS) and overall survival (OS). The median OS in the TM‐positive patients was 32.9 mo, which was better than the 20.0 mo in TM‐negative patients (P =.006). TM positivity retained its significance on multivariate analysis for DFS (hazard ratio [HR] 0.651, 95% confidence interval [CI] 0.433–0.979, P =.039) and OS (HR 0.569, 95% CI 0.376–0.862, P =.008). Conclusions The tumor expression of TM is a favorable factor for OS in resected pancreatic invasive ductal adenocarcinoma., We found that thrombomodulin (TM) expression was strongly correlated with cancer prognosis and lymphatic invasion. TM expression inhibited cancer recurrence and translymphatic cancer metastasis. TM expression might be a novel target for developing treatment strategies in pancreatic cancer.

BackgroundCholesterol crystal embolism (CCE) following transcatheter arterial chemoembolization (TACE) is rare.Case presentationA 71-year-old man underwent TACE for recurrence of hepatocellular carcinoma (HCC). On postoperative day (POD) 5, he developed abdominal pain and fever. Computed tomography revealed intraperitoneal free air. The patient was diagnosed with gastrointestinal perforation with peritonitis, for which partial intestinal resection and covering ileostomy were performed. Histological examination revealed perforation of the small intestine caused by CCE. The patient made a satisfactory recovery and was discharged on POD 30. The patient showed no recurrence of cholesterol crystal embolism or HCC for 2 years after surgery.ConclusionWe reported a successfully treated case of ischemic small bowel perforation due to cholesterol crystal embolism following transcatheter arterial chemoembolization for recurrent HCC.

The aim of this study was to evaluate the clinical utility of a novel diagnostic algorithm based on serum d-dimer levels for venous thromboembolism (VTE) after hepatectomy. We retrospectively analyzed 742 consecutive patients who underwent hepatectomy in our hospital from 2009 to 2019. From 2015, we routinely measured serum d-dimer level postoperatively and computed tomography was performed when d-dimer level was ≥ 20 μg/mL. VTE was diagnosed in 26 patients and pulmonary embolism (PE) was diagnosed in 18 patients. Multivariate analysis revealed that resected liver weight ≥ 120 g is a significant predictor of VTE (P = 0.011). The incidence of VTE from 2015 to 2019 was greater than that from 2009 to 2014 (5.0% versus 2.1%, P = 0.044). The number of low-risk PE patients between 2015 and 2019 was significantly greater than that between 2009 and 2014 (P = 0.013). There was no in-hospital mortality of patients with PE from 2015 to 2019. Patients who undergo hepatectomy are at high risk for VTE, especially when the resected liver weight is high. The proposed diagnostic algorithm based on serum d-dimer levels for VTE after hepatectomy can be useful for early diagnosis.

Aim This study sought to evaluate the incidence, risk factors, and clinical outcomes of portal vein thrombosis after hepatectomy. Furthermore, we proposed a novel classification and treatment strategy for portal vein thrombosis after hepatectomy. Methods We retrospectively analyzed 398 patients who underwent hepatectomy and enhanced computed tomography imaging within 14 days after surgery in our hospital from 2009 to 2019. Portal vein thrombosis was classified into three categories according to the location of the thrombus – main, hilar, and peripheral – with main portal vein thrombosis further subclassified into three grades. Each patient's treatment strategy was determined based on their portal vein thrombosis classification and grading. From 2015, enhanced computed tomography imaging was performed routinely on patients who underwent anatomical hepatectomy on postoperative day 7. Results Portal vein thrombosis was diagnosed in 57 patients (14.3%) during the study period. Multivariate analysis revealed that a Pringle maneuver time of 75 minutes or longer was a significant predictor of portal vein thrombosis (P = .012). In total, 52 patients (91%) with portal vein thrombosis recovered by surgery, anticoagulant therapy, or without specific treatment. There was no instance of mortality recorded. Conclusions Patients who undergo hepatectomy are at high risk for portal vein thrombosis, especially when the Pringle maneuver time is long. The proposed classification and treatment strategy may be useful for clinical management of patients with portal vein thrombosis after hepatectomy., Patients who undergo hepatectomy are at high risk for portal vein thrombosis, especially when the Pringle maneuver time is long. The proposed classification and treatment strategy may be useful for clinical management of patients with portal vein thrombosis after hepatectomy.

Highlights • Postoperative subphrenic abscess caused by Clostridium perfringens is rare after hepatic resection. • Clostridium perfringens causes severe sepsis with high mortality rate. • Early antibiotic and surgical treatment for the focus of infection is significantly improve in the survival rate., Background Subphrenic abscess caused by Clostridium perfringens is rare after hepatic resection. We herein report such a case after hepatic resection for hepatocellular carcinoma following treatment of emphysematous cholecystitis. Case presentation A 69-years-old man with chronic hepatitis B, was admitted to our hospital for right subcostal pain and loss of appetite. Computed tomography (CT) revealed emphysematous cholecystitis, for which percutaneous transhepatic gallbladder drainage was performed. Clostridium perfringens was identified from the culture of the bile. Imaging studies immediately demonstrated hepatocellular carcinoma with right lobe of the liver, for which the patients underwent hepatic resection and cholecystectomy concomitantly. After operation, the patient developed emphysematous subphrenic abscess on postoperative day 15, for which CT-guided percutaneous drainage was performed. Clostridium perfringens was identified from the culture of the abscess fluid. The patient was given Ciprofloxacin and Clindamycin and made a satisfactory recovery. The patient was discharged on POD 95 and remains well with no evidence of tumor recurrence as of 8 years after resection. Conclusion We herein reported a subphrenic abscess due to Clostridium perfringens after hepatic resection for hepatocellular carcinoma following emphysematous cholecystitis.

Background Inflammation-based prognostic scores are associated with tumor recurrence and survival in various cancers. The aim of this study was to identify the significance of inflammation-based prognostic scores and to detect the most useful score in patients with distal extrahepatic bile duct cancer after pancreaticoduodenectomy. Methods Between 2000 and 2015, 121 patients were enrolled in this retrospective study. The relationship between clinicopathological variables including various prognostic scores and disease-free (DFS) as well as overall (OS) survival was investigated by univariate analysis. The area under the receiver operating characteristics curve was calculated to compare the predictive ability of each scoring system. Multivariate analysis was performed to identify the clinicopathological variables associated. Results In univariate analysis, Glasgow prognostic score (GPS), mGPS, C-reactive protein/Alb ratio score, prognostic index, and preoperative monocyte count were significant risk factors for both DFS and OS. The area under the receiver operating characteristics curve of GPS is consistently larger in comparison with other four scores in both DFS as well as OS. In multivariate analysis, GPS was an independent risk factor of both tumor recurrence and poor prognosis. Conclusions GPS score is an independent tumor recurrence and prognostic factor in patients with distal extrahepatic bile duct cancer and is superior to the other prognostic scores.

The benefit of preoperative biliary drainage for patients with operable periampullary cancers is controversial because biliary drainage would activate inflammatory response such as cholangitis. The aim of this study was to identify a novel prognostic score in patients with operable periampullary cancers including pancreatic cancer and extrahepatic distal bile duct cancer with a typical reference to preoperative biliary drainage and inflammatory status. Between 2000 and 2015, 246 patients were enrolled in this retrospective study. The patients were divided into four groups of the following three factors; the presence of preoperative biliary drainage, decreased serum albumin value ( 1.0 mg dl−1). The relationship between clinicopathological variables and disease-free survival (DFS) as well as over-all survival (OS) was investigated by univariate and multivariate analyses. To compare the sensitivity and specificity among the types of cancer, the area under the receiver operating characteristics curve (AUC) was evaluated in patients with pancreatic cancer and extrahepatic distal bile duct cancer. In multivariate analysis of DFS and OS, the novel prognostic factor combining preoperative biliary drainage and inflammatory status was an independent risk factor of tumor recurrence and prognosis as well as differentiation of the tumor and resected margin. The novel prognostic score combining preoperative biliary drainage and inflammatory status may be an independent predictor of tumor recurrence and prognosis in patients with periampullary cancers.

The aim of this retrospective study was to evaluate a revised classification system for predicting the difficulty of laparoscopic partial liver resection. Patients who had undergone initial laparoscopic partial liver resection for a solitary lesion from January 2012 to February 2021were classified into two groups according to the type of procedure performed, “scooping-out” versus “cutting.” The participants were then further divided into “small” and “large” subgroups according to the tumor’s depth and diameter. Finally, they were categorized into two groups, namely “standard” and “advanced.” Operative outcomes were compared between the two groups and the proposed revised system for classifying difficulty of laparoscopic partial liver resection compared with the existing scoring system. Of the 65 procedures assessed, 40 were categorized as standard and 25 as advanced. Tumor size (P

The superiority of outcomes associated with anatomical resection (AR) versus those associated with non-anatomical resection (NAR) remains controversial in patients with hepatocellular carcinoma (HCC). The aim of this study was to evaluate the significance of AR on therapeutic outcomes of patients with small HCCs (≤ 5 cm), using propensity score–matched (PSM) analysis. A total of 195 patients who had undergone elective hepatic resection for small HCCs (≤ 5 cm) were included in this study. We conducted PSM analysis for baseline characteristics (age, sex, hepatitis virus status, retention rate of indocyanine green at 15 min, and Child-Pugh grade), preoperative serum α-fetoprotein, and tumor characteristics (tumor size, tumor number, portal vein invasion, and surgical margin status) to eliminate potential selection bias. The prognostic significance of AR on the disease-free and overall survival was analyzed in patients selected by PSM analysis. Applying PSM analysis, the patients were divided into PSM-AR (N = 66) and PSM-NAR (N = 66) groups. Disease-free survival was significantly better in the PSM-AR group than that of the PSM-NAR group (P = 0.018), while there was no significant difference in the overall survival between the PSM-AR and PSM-NAR groups (P = 0.292). The univariate HRs of the PSM-AR group were 0.55 (95% CI, 0.33–0.90) for disease-free survival and 0.61 (95% CI, 0.24–1.53) for overall survival, respectively. Remnant liver recurrence was significantly lower in the AR group (P = 0.014). AR may improve the disease-free survival in HCC patients with tumors of ≤5 cm diameter.

Aim We investigated the prognostic impact of osteosarcopenia, which is the combination of osteopenia and sarcopenia, in patients with colorectal liver metastases (CRLM) after hepatic resection. Methods One hundred and eighteen patients were analyzed retrospectively. Osteopenia was evaluated with computed tomographic measurement of pixel density in the midvertebral core of the 11th thoracic vertebra. Sarcopenia was evaluated with psoas muscle areas at the third lumbar vertebra. Osteosarcopenia was defined as the concomitant occurrence of osteopenia and sarcopenia. Results Osteosarcopenia was identified in 38 (32%) of the patients. In univariate analysis, the overall survival was significantly worse in patients with lymph node metastases (P = .01), extrahepatic lesion (P = .01), sarcopenia (P = .02), osteosarcopenia (P, This study aimed to investigate the impact of preoperative osteosarcopenia, which is defined as the concomitant occurrence of osteopenia and sarcopenia, on the outcomes of patients with colorectal liver metastases (CRLM) after hepatic resection in conjunction with other nutritional markers including sarcopenia and osteopenia, as well as inflammatory parameters. We found that osteosarcopenia was the strong predictor for outcomes in patients who underwent liver resection for CRLM. To the best of our knowledge, this is the first study to report the prognostic value of osteosarcopenia in patients with malignancies.

Although pancreatectomy with lymph node (LN) and nerve plexus dissection has usually been performed for pancreatic cancer, recent randomized controlled trials have questioned its survival benefits. However, superior mesenteric artery (SMA) LN dissection has still been included in standard treatment guidelines. A total of 94 patients who underwent pancreaticoduodenectomy for resectable pancreatic cancer without LN enlargement around the SMA on imaging were identified between 2008 and 2017. Disease-free survival (DFS), overall survival (OS), and complications were compared between those with LN and hemicircumferential nerve plexus dissection around the SMA (SMA ly+) and those without thorough LN and nerve plexus dissection around the SMA (SMA ly−) after adjusting for major prognostic factors. A total of 78 and 16 patients with SMA ly+ and SMA ly− were identified, respectively. Our data demonstrated no difference in DFS and OS rates between both groups (P = 0.18 and 0.83, respectively). Patients with SMA ly+ had significantly more complications, particularly severe diarrhea, compared to those with SMA ly− (P = 0.001). LN and nerve plexus dissection around the SMA did not prolong survival and significantly increased the frequency of severe diarrhea, suggesting that performing in all cases carries less practical significance.

Although arterial pseudoaneurysm is one of the most serious complications after pancreatic surgery, the best practice with maximum efficacy and minimum adverse effects to overcome such a serious situation has not yet been elucidated. We performed endovascular micro-arterial stenting (EMAS) to manage this serious situation while preserving a sufficient hepatic arterial flow, and herein report the technical details and challenges of the procedure. Dilation of the stent using a balloon catheter to adhere to the parent artery, and embolization of the surrounding artery to prevent type I and type II endo-leaks are the most important points for ensuring a successful procedure. We applied this technique to 6 cases of hepatic arterial pseudoaneurysm, with a mean size of 6.5 ± 1.3 mm. The mean time of the procedure was 81 ± 22 min, without adverse events, including hepatic necrosis or arterial bleeding. EMAS may be the ideal procedure for treating pseudoaneurysm after pancreatic surgery while preserving the hepatic arterial inflow.

Background The preoperative systemic inflammation has been reported to predict tumor recurrence and survival in various cancers, including colorectal liver metastases (CRLM). However, more sensitive biomarker is required to improve perioperative management of CRLM. Therefore, we developed a novel indicator; C-reactive protein-to-lymphocyte ratio (CLR). The aim of this study is to evaluate the prognostic significance of CLR in patients with CRLM after hepatic resection. Materials and methods The study comprised 197 patients who had undergone hepatic resection for CRLM between January 2000 and December 2018. We retrospectively investigated the relation between CLR and disease-free survival and overall survival after hepatic resection and compared their prognostic significance with that of the C-reactive protein-to-albumin ratio and neutrophil-to-lymphocyte ratio. Results Optimal cutoff level of the CLR by receiver operating characteristics analysis was 62.8 × 10−6. By multivariate analysis, CLR was an independent predictor of disease-free survival [hazard ratio (HR): 1.463, 95% confidence interval (CI): 1.003-2.135, P = 0.048), whereas lymph node metastases>4 (HR: 1.804, 95% CI: 1.100-2.958, P = 0.019) and CLR (HR: 1.656, 95% CI: 1.007-2.724, P = 0.047) were independent predictors of overall survival, while the C-reactive protein-to-albumin ratio and neutrophil-to-lymphocyte ratio were not. Conclusions CLR may be an independent and significant indicator of poor long-term outcomes in patients with CRLM after hepatic resection.

Introduction: Primary splenic lymphoma is a rare condition that accounts for approximately 1% of non-Hodgkin's lymphoma. No primary splenic follicular lymphoma with idiopathic thrombocytopenic purpura (ITP) has been reported in the literature. Case presentation: A 41-year-old man was diagnosed with idiopathic thrombocytopenic purpura (ITP), and received steroid maintenance treatment with oral prednisolone 13 mg/d for 6 years. However, the platelet counts were 20 × 103 /μL or less. Abdominal enhanced computer tomography (CT) revealed splenomegaly. He underwent laparoscopic splenectomy after preoperative high-dose immunoglobulin preparation (30 mg/d intravenously for 5 days) which were effective in the improvement of platelets count (130 × 103 /μL). The histologic diagnosis was B cell type follicular lymphoma of the spleen. Fluorescent in situ hybridization (FISH) revealed a t(14; 18)(q32; q21) translocation, which supported the diagnosis of primary follicular lymphoma of the spleen. After the operation, the patient showed satisfactory recovery, and was discharged on postoperative day 7. He remains well with the platelet count of more than 200 × 103 / μl without medication. We herein report such a case. Conclusion: To the best of our knowledge, this is the first reported case of splenic primary follicular lymphoma with ITP.

Background Calcifying fibrous tumor (CFT) is a rare benign soft tissue lesion. Case presentation A 30-year-old woman was admitted to our hospital with complaints of epigastralgia. A 15-mm submucosal tumor was identified in the greater curvature of the superior body of the stomach by upper gastrointestinal endoscopy. Endoscopic ultrasonography revealed a hypoechoic lesion with an acoustic shadow consistent with calcification. Computed tomography showed a gastric tumor with calcification. A gastrointestinal stromal tumor was diagnosed, and gastric wedge resection was performed by laparoscopy and endoscopy cooperative surgery. On pathological examination, the tumor was identified to be a CFT. Postoperative serum IgG4 levels were 26.0 mg/dl, which supported the diagnosis of probable immunoglobulin G (IgG) 4-related disease, according to the comprehensive diagnostic criteria of IgG4-related disease. The patient was discharged on postoperative day 7 and remains well with no evidence of tumor recurrence for 2 years after resection. Conclusion We herein reported a patient with a gastric CFT suspected to be complicated with immunoglobulin G4-related disease that was successfully treated by laparoscopy and endoscopy cooperative surgery.

BACKGROUND/AIM Prediction of local recurrence and distant metastasis is important for patients with pancreatic cancer following pancreatic resection. The aims of this study were to identify a novel prognostic score which combines distance from common hepatic artery (CHA) or superior mesenteric artery (SMA) and examine serum CA19-9 for predicting local recurrence in patients with pancreatic cancer following resection. PATIENTS AND METHODS This retrospective study comprised 149 patients who went through elective pancreatic resection for pancreatic cancer between June 2007 and December, 2017. We established new scores (CHA score and SMA score) using the distance between CHA or SMA and the tumor measured by preoperative CT scan in combination with preoperative serum CA19-9 values. We evaluated the relationship between the scores and local recurrence of pancreatic cancer. Finally, we investigated the relationship between the scores and local recurrence-free survival as well as the overall survival. RESULTS The optimal cut-off levels of the distance between CHA or SMA and the tumor, as determined by ROC analysis, were 20.55 and 10.9 mm, respectively. In a logistic progression model, demonstrated by multivariate analysis, lymphatic invasion (p=0.002), preoperative serum CA19-9 (p=0.007) and SMA score (p=0.004) were identified to be independent predictors of local recurrence in patients with pancreatic cancer following resection. In a Cox progression model, demonstrated by multivariate analysis, intraoperative blood loss (p=0.022), lymphatic invasion (p=0.001) and SMA score (p

Aim Prognostic factors of recurrence and survival in various cancer types have been reported and include C-reactive protein (CRP)-based measures as evidenced by the Glasgow prognostic score (GPS), as well as peripheral blood cell-based prognostic values such as the prognostic index (PI), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR). The aim of this study was to identify significant prognostic values and compare them for suitability for use in patients after curative pancreatic resection for pancreatic cancer. Materials and methods Between 2000 and 2015, 188 patients were enrolled in this retrospective study. The relationship between clinicopathological variables including various prognostic values and disease-free (DFS) and overall (OS) survival was investigated by univariate analysis. The area under the receiver operating characteristics curve (AUC) was evaluated to compare the predictive ability of each of these scoring systems. Multivariate analysis was then performed to identify clinicopathological variables that associated DFS and OS. Results In univariate analysis, GPS, modified GPS, CRP to albumin ratio and PI were significant risk factors for both DFS and OS. The AUC of CRP-based scores (GPS, modified GPS, and CRP to albumin ratio) were consistently larger in comparison with PI, which consists of both CRP and peripheral blood cell scores, at all time points for both DFS and OS. In multivariate analysis, GPS was the only independent risk factor of tumor recurrence and survival. Conclusion CRP-based prognostic scores have an independent value for both tumor recurrence and prognosis in patients after curative resection for pancreatic cancer, and are superior to other peripheral blood cell count-based prognostic scores.

A 54-year-old woman underwent living donor liver transplantation (LDLT) for primary biliary cholangitis (PBC) three years earlier. She took cyclosporine A (CyA) 150 mg/day as immunosuppression for prevention of rejection and PBC recurrence. Routine upper gastrointestinal endoscopy showed chronic atrophic gastritis and hyperplastic polyp, and rapid urease test was positive. Anti-Helicobacter pylori (H. pylori) serum IgG was elevated to 51 U/ml. We performed H. pylori eradication therapy with amoxicillin, clarithromycin and lansoprazole measuring the blood CyA concentration every day. Although the blood CyA concentration reached a peak (the concentration 2 hours after the administration: 818 ng/ml) on the second day, she did not develop renal dysfunction or other obvious adverse effects. Five weeks after the treatment, we confirmed eradication of H. pylori with the urea breath test. We herein reported a case of successful eradication of H. pylori in a LDLT recipient on immunosuppressive therapy with CyA without adverse effects.

Spontaneous biliary peritonitis is rare in adults. We herein report a case of spontaneous biliary peritonitis. An 84-year-old man was admitted to our hospital for abdominal pain for 5 days. He developed fever, jaundice, and abdominal rigidity. Computed tomography (CT) revealed massive ascites in the omental bursa and around the liver. The ascites obtained by diagnostic paracentesis was dark yellow-green in color, which implied bile leakage. With a diagnosis of bile peritonitis, the patient underwent emergency exploratory laparotomy. There was massive biliary ascites in the abdominal cavity, especially in the omental bursa. Because exploration failed to demonstrate the perforation site in the gallbladder and biliary duct, we performed abdominal lavage alone. Postoperative endoscopic retrograde cholangiopancreatography showed stones in the common bile duct, and there was no evidence of biliary leakage. Endoscopic retrograde biliary drainage was performed using a plastic stent to reduce the pressure of the common bile duct. After the operation, the patient showed satisfactory recovery and started oral intake on postoperative day 8. However, the patient developed heart failure due to renal dysfunction with nephrotic syndrome at 1 month after the operation. With a diagnosis of rapidly progressive glomerulonephritis due to immune complex, the patient received steroid treatment for nephritis, diuretics, and carperitide for heart failure. Although heart failure and renal dysfunction improved by these treatment, the patients developed toxic epidermal necrolysis which was refractory to intensive treatments including steroid pulse and immunoglobulin, and the patient died 76 days after the operation.
