ABSTRACT: BACKGROUND: An inflammation-based prognostic score, the modified Glasgow Prognostic Score (mGPS), has been established as a useful tool for predicting postoperative outcome in patients with cancer. However, no studies have investigated the usefulness of the mGPS for prognostication in patients undergoing palliative surgery for unresectable malignant biliary obstruction (UMBO). The present study was conducted to investigate whether the mGPS is useful for predicting the postoperative survival of patients undergoing intraoperative placement of an expandable metal stent for UMBO, or not. METHODS: The mGPS was calculated as follows: patients with both an elevated level of C-reactive protein (CRP) (>1.0 mg/dL) and hypoalbuminemia (<3.5 g/dL) were allocated a score of 2. Patients with only an elevated CRP level were allocated a score of 1, and patients without an elevated CRP level (≤1.0 mg/dL) were allocated a score of 0. Postoperative survival was evaluated by Kaplan-Meier analysis and log rank test. The significance of risk factors for postoperative survival was evaluated with the Cox proportional hazards model. RESULTS: Kaplan-Meier analysis revealed that patients with mGPS 0 (n = 36) and 1 (n = 7) had better postoperative survival (p = 0.017) than patients with mGPS 2 (n = 17). The 6-month and 1-year survival rates of patients with mGPS 0 and 1 were 58.1 and 27.3 %, and those for patients with mGPS 2 were 25.0 and 6.2 %, respectively. Multivariate analysis revealed that mGPS (0, 1/2) was a significant risk factor for postoperative survival (hazard ratio 3.271; 95 % CI 1.109-9.649; p = 0.032). CONCLUSION: The mGPS is not only one of the most significant predictors of postoperative survival for UMBO patients receiving intraoperative biliary stenting but also a useful indicator capable of dividing such patients into two independent groups before surgery.

ABSTRACT: : Delayed gastric emptying (DGE) is one of the major complications after pancreaticoduodenectomy (PD), occurring in 14% to 61% of cases. There have been no studies that compare the incidence of DGE in terms of the reconstruction method of gastrojejunostomy performed in subtotal stomach-preserving pancreaticoduodenectomy (SSPPD). The objective of this study was to evaluate the superiority of Billroth II (B-II) to Roux-en Y (R-Y) reconstruction on decreasing the incidence of delayed gastric emptying DGE after SSPPD by a prospective randomized controlled trial.
: Between April 2008 and August 2011, 101 patients who underwent SSPPD for pancreatic head or periampullary diseases were randomly allocated to B-II reconstruction (n = 52) and R-Y reconstruction (n = 49) groups. The primary endpoint was incidence of DGE.
: DGE occurred in 5.7% of patients in the B-II group and in 20.4% of patients in the R-Y group (P = 0.028). Patients in the B-II group had a significantly shorter hospital stay after operation than patients in the R-Y group (31.6 ± 15.0 days vs. 41.4 ± 20.5 days, P = 0.037). In terms of postoperative complications, the incidence of pancreatic fistula was significantly higher in patients with DGE (38.5%) than in patients without DGE (14.8%) (P = 0.037).
: It is suggested that the incidence of DGE after SSPPD can be decreased by using B-II rather than R-Y reconstruction for gastrojejunostomy.(Clinical Trials Registry, UMIN-CTR: http://www.umin.ac.jp/ctr/, ref no. UMIN000003535).

ABSTRACT: BACKGROUND: The aim of this study was to compare postoperative survival between hepatocellular carcinoma (HCC) patients with and without viral infection. METHODS: From among 398 HCC patients in our collected database, 377 who underwent surgery were enrolled. The patients were divided into 2 groups: group 1, those who had no hepatitis B virus or hepatitis C virus infection, and group 2, those who had hepatitis B virus or hepatitis C virus infection. Univariate analysis was performed to compare clinical factors, including viral infection, with overall survival. Kaplan-Meier analysis and the log-rank test were used to evaluate the overall and disease-free survival curves for the 2 groups. RESULTS: Univariate analysis showed that viral infection showed no such association. Moreover, Kaplan-Meier analysis and the log-rank test revealed no significant intergroup differences in either overall or disease-free survival. CONCLUSIONS: The presence or absence of viral infection shows no significant association with the postoperative survival of patients undergoing surgery for HCC.

ABSTRACT: The aim of this study was to investigate whether menatetrenone (MNT) suppresses hepatocellular carcinoma (HCC) recurrence in patients undergoing hepatectomy. Between January 2005 and September 2009, 101 patients who underwent curative hepatectomy for primary HCC were enrolled in the study. Patients were divided into two groups: a non-MNT group (n=51), and an MNT group (n=50) that was administered 45 mg of MNT daily. During the observation period, recurrence was observed in 33 patients in the non-MNT group and in 28 patients of the MNT group (p=0.545). In patients with a preoperative Des-γ-carboxy-prothrombin (DCP) level lower than 40 AU/l (n=38), the cumulative disease-free survival rates at 12, 36, and 60 months in the non-MNT group, were 81.3%, 0.0%, and 0.0%, respectively, while those in the MNT group were 78.3%, 58.1%, and 31.0%, respectively (p=0.060). MNT has a moderately suppressive effect on HCC recurrence after hepatectomy, especially in patients with a normal preoperative DCP level.

ABSTRACT: BACKGROUND: The current study was conducted to evaluate the safety and utility of intraoperative transhepatic biliary stenting (ITBS) in patients with unresectable malignant biliary obstruction (UMBO) diagnosed intraoperatively. METHODS: In this study, 50 patients who underwent ITBS for UMBO between April 2001 and May 2009 were retrospectively reviewed. For 26 patients who underwent preoperative percutaneous transhepatic biliary drainage (PTBD), the expandable metallic stent (EMS) was inserted intraoperatively by the PTBD route in a single stage. For 24 patients, the intrahepatic bile ducts were intentionally dilated by injection of saline via the endoscopic nasobiliary drainage or the percutaneous transhepatic gallbladder drainage route, and the puncture was performed under intraoperative ultrasound guidance followed by guidewire and catheter insertion. Thereafter, the EMS was placed in the same manner. The initial postoperative complications and long-term results of ITBS were evaluated. RESULTS: In all cases, ITBS was technically successful. Stenting alone was performed in 22 patients and stenting combined with other procedures in 28 patients. Hospital mortality occurred for three patients (6 %), and complication-related mortality occurred in two cases (4 %). There were nine cases (18 %) of postoperative complications. The median survival time was 179 days, and the EMS patency time was 137 days. During the follow-up period, EMS occlusion occurred in 23 cases (46 %). Best supportive care was a significant independent risk factor for early mortality within 100 days after ITBS (p = 0.020, odds ratio, 9.398). CONCLUSIONS: Single-stage ITBS is feasible for palliation of UMBO and seems to have a low complication rate.

ABSTRACT: Hepcidin, a key regulator of iron homeostasis, is also a marker of acute inflammation. In the present study we investigated the changes in the serum hepcidin level and correlations between hepcidin and other markers of acute inflammation during the perioperative period in patients after abdominal surgery.
Serum hepcidin, hemoglobin (Hb), hematocrit (Ht), white blood cell (WBC) count, frequency of neutrophils, and C-reactive protein (CRP) were measured preoperatively (Pre), and on postoperative days (POD) 1, 3, 7, and 14.
In patients undergoing gastrectomy, the median levels of hepcidin preoperatively and on POD 1, 3, 7, and 14 were 6.5, 53.1, 31.7, 15.6, and 4.0 ng/dl, respectively (p < 0.0001). The corresponding levels in colectomy patients were 8.5, 78.3, 60.1, 49.7, and 8.4 ng/dl, respectively (p = 0.0002); those in hepatectomy patients were 6.6, 16.3, 3.5, 13.4, and 3.4 ng/dl, respectively (p = 0.0022); and those in patients undergoing surgery for diffuse peritonitis were 24.8, 50.1, 43.1, 31.2, and 31.7 ng/dl, respectively (p = 0.4933). There were no significant decreases in Hb and Ht in the patients undergoing gastrectomy, colectomy, or surgery for diffuse peritonitis. The level of hepcidin was significantly correlated with the WBC count, frequency of neutrophils, and CRP level during the perioperative period for all four types of operation.
Like other inflammatory markers, an increase in the level of hepcidin (i.e., a hepcidin storm) occurs in the acute phase after gastrectomy, colectomy, hepatectomy, and surgery for diffuse peritonitis.

ABSTRACT: Pancreatic fistula (PF) after pancreaticoduodenectomy (PD) is still a severe complication and a challenging problem. The common risk factors are the soft pancreas and small pancreatic duct of the remnant pancreas. Those two risk factors were recognized during surgery. On the other hand, a preoperatively determined risk factor of PF is unclarified. We conducted a retrospective analysis of 203 patients consecutively treated by PD from April 2000 to October 2010. PF was defined according to the criteria of the International Study Group of Pancreatic Fistula. Clinical and pre- and intraoperative data were compared between PF and non-PF patients. The recommended cutoff value of body mass index (BMI) as 20 kg/m(2) was defined by receiver operating characteristic curve analysis. PF occurred in 53 (26.1%) of 203 patients. In univariate analysis, BMI and soft remnant pancreas were found to be risk factors of PF (P = 0.027, P = 0.005). In multivariate analysis, BMI and soft pancreas were also risk factors of PF (P = 0.040, P = 0.005). Patients with PF had a significantly longer hospital stay than non-PF patients (P = 0.005). High BMI and soft pancreas were significant risk factors for PF.

ABSTRACT: Primary hepatic leiomyosarcoma are rare tumors with less than 30 cases reported in the English literature. Non specific presentations and often diagnosis delayed until they reach a large size, is the norm with therapy leading to an often dismal prognosis. A 67-year-old man presented complaining of abdominal pain and a palpable abdominal mass since Jan 2010. Abdominal ultrasonography and abdominal computed tomography revealed a large tumor in the left lobe of the liver. Surgical exploration was undertaken and an extended left hepatectomy with extension onto the dorsal part of segment 8 preserving the MHV with partial resection of segment 6 was undertaken. The weight of the resected specimen was 1300 g of the left lobectomy specimen and 8 g of the segment 6 partial resection specimen. The pathology report confirmed the diagnosis of leiomyosarcoma. On immunohistochemistry, the tumor cells were positive for smooth muscle actin stain. The patient is on regular follow up and is currently 9 mo post resection with no evidence of recurrence. We report the case of a resected primary hepatic leiomyosarcoma and emphasize the need for a global database for these rare tumors to promote a better and broader understanding of this less understood subject.

ABSTRACT: We describe a rare case of epidermoid cyst arising in an intrapancreatic accessory spleen that presented as a cystic mass in the tail of the pancreas, and for which laparoscopic distal pancreatectomy was performed successfully. A 36-year-old woman with a cystic mass in the tail of the pancreas, which had been discovered incidentally at a medical checkup, was referred to our department for further examination. Endoscopic retrograde cholangiopancreatography, endoscopic ultrasonography and positron emission tomography demonstrated a multilocular cyst in the tail of the pancreas without any evidence of malignancy, although differential diagnosis was extremely difficult because of the neoplasm-like appearance of the lesion. Therefore, we performed laparoscopic distal pancreatectomy under a preoperative diagnosis of mucinous cystic neoplasm. Postoperative pathologic examination demonstrated an epidermoid cyst arising from a heterotopic spleen within the pancreas. This is the first report of successful laparoscopic distal pancreatectomy for an epidermoid cyst arising in an intrapancreatic accessory spleen. One virtually has no chance to diagnose an epidermoid cyst in an accessory spleen on the basis of preoperative diagnostic workup, and consequently the type of surgical resection (open vs. laparoscopic) would be conditioned by factors other than the clinical entity suspected at the preoperative period.

ABSTRACT: To evaluate the influence of body mass index (BMI) on postoperative death in patients undergoing surgery for HCC.
Three hundred forty-two patients were enrolled, and divided into three groups: Group A, BMI <22.5; Group B, BMI ≥22.5 to <25; Group C, BMI ≥25. Univariate and multivariate analyses of postoperative death were performed to compare BMI with clinical factors. Kaplan-Meier analysis and log rank test were used to compare such outcome in Groups A, B, and C.
Kaplan-Meier analysis and log rank test revealed that Group A had a higher rate of postoperative death than Group B or C (P = 0.010). Univariate and multivariate analyses selected being underweight (Group B, C/Group A) (odds ratio, 1.829; 95% C.I., 1.091-3.068; P = 0.022) as one of the factors predictive of postoperative death, together with aspartate aminotransferase level (P = 0.042) and HCC growth pattern (P = 0.032).
BMI is a simple but important predictor of postoperative death in patients undergoing surgery for HCC, and is able to classify such patients into three independent groups.

ABSTRACT: Few studies have investigated grading of liver metastasis (GLM) in patients with liver metastases from colorectal cancer (LM-CRC).
To screen for the most useful predictive factors in patients undergoing hepatic resection for LM-CRC, clinico-pathological factors were subjected to uni- and multivariate analyses.
One hundred and twenty-five patients were evaluated retrospectively. Univariate analyses using clinico-laboratory factors demonstrated that nomogram, gender, CRP, albumin, number of hepatic resections, liver metastasis (H) and GLM were related to postoperative death. Multivariate analysis using these seven factors disclosed that albumin (OR, 6.949; 95% CI, 1.994-24.22; p=0.002), CRP (OR, 6.977; 95% CI, 1.937-25.14; p=0.003) and GLM (OR, 2.819; 95% CI, 1.082-7.346; p=0.034) were associated with postoperative death. Kaplan-Meier analysis and log rank test revealed that higher GLM (p<0.001) and CRP (p<0.001) were associated with a higher rate of postoperative death. GLM was able to divide the patients into three independent groups with significantly different total nomogram counts (p<0.001, Kruskal-Wallis test).
GLM is able to classify patients with LM-CRC into three independent groups and offers reliable information for predicting postoperative death in such patients.

ABSTRACT: Few studies have investigated the Glasgow Prognostic Score (GPS) in patients with hepatocellular carcinoma (HCC).
This study compared the prognostic value of the GPS and Cancer of the Liver Italian Program (CLIP) score in patients undergoing surgery for HCC.
A total of 398 patients were evaluated retrospectively. Kaplan-Meier analyses revealed that GPS (P < .001) and CLIP score (P < .001) were associated with overall survival. GPS could classify patients with low CLIP score (0 or 1) into 3 independent groups (P < .001). Univariate analyses selected GPS (P = .006) and CLIP score (P = .002) as the predictive factors associated with overall survival. Multivariate analysis using these 2 scoring systems disclosed that both GPS (P = .025) and CLIP score (P = .010) were associated with overall survival.
GPS is not only an important predictor of overall survival after surgical treatment of HCC as well as CLIP score, but also is able to clearly divide patients with low CLIP score into 3 independent groups.

ABSTRACT: To assess and compare the predictive values of the hepatic Glasgow Prognostic Score (hGPS) and Cancer of the Liver Italian Program (CLIP) score in patients undergoing surgery for primary hepatocellular carcinoma (HCC).
The hGPS was calculated as follows: patients with an elevated level of C-reactive protein (CRP) (>0.3 mg/dl) were allocated a hGPS of 1 or 2 depending on the absence or presence of hypoalbuminemia (<3.5 g/dl), and patients without an elevation of the CRP level (≤ 0.3 mg/dl) were allocated a hGPS of 0.
Three hundred patients were evaluated. The hGPS divided patients into three independent groups, and that a hGPS of 2 predicted a higher mortality rate (P < 0.001) than a hGPS of 0 or 1. Univariate analysis demonstrated that hGPS (0, 1/2) (P = 0.010) was one of the factors predictive of postoperative mortality, along with the CLIP score (0, 1/≥ 2) (P = 0.021). Comparative analysis using these two factors showed that the hGPS was predictively superior to the CLIP score (P = 0.033).
The hGPS is able to divide patients undergoing surgery for primary HCC into three independent groups, and is considered to be an important factor predictive of postoperative mortality in such patients.

ABSTRACT: The treatment strategy for hepatocellular carcinomas (HCCs)≤2 cm (HCC2-) is still controversial. In this study, we retrospectively analyzed clinicopathological data for HCC2- and HCCs>2 cm (HCC2+) to establish the treatment strategy for HCC2-.
Between April 2000 and December 2008, 206 patients with single HCC, who underwent hepatectomy for the first time, and whose outcomes could be tracked, were included in the study. There were 46 HCC2- and 160 HCC2+ patients. Survival and disease-free survival rates were compared between the two groups, in relation to various clinicopathological data.
The 1-, 3-, and 5-year overall survival rates were 100%, 92.6%, and 72.8% for HCC2- and 93.3%, 72.4%, and 57% for HCC2+, respectively (P=0.0098). The 1, 3, and 5-year disease-free survival rates were 86%, 42.6%, and 31% for HCC2-, and 64.7%, 35.9%, and 12.5% for HCC2+, respectively (P=0.0642). Survival rates were better for HCC2- than for HCC2+ in terms of abnormal serum des-gamma-carboxy prothrombin, Child-Pugh Class A, single infection with HBV or HCV, and operative method used for anatomical resection, irrespective of ICG R15. Disease-free survival rates were better for HCC2- than for HCC2+ in terms of Child-Pugh Class A, and operative method used for anatomical resection.
HCC2- has a better clinical outcome than HCC2+ after hepatic resection. Especially, HCC2- with an abnormal DCP value, Child-Pugh Class A, single infection with HBV or HCV, and anatomical resection, yields better outcomes. Even for HCC2- in patients with good liver function, anatomical resection is recommended.

ABSTRACT: The duodenum is a central organ for iron absorption. This study was performed to evaluate changes in body iron concentration and other iron-related molecules sequentially, in patients undergoing pancreatoduodenectomy (PD).
Twenty-one patients who had undergone PD at our department were enrolled in the study. Measurements of serum iron (sFe), total iron-binding capacity (TIBC), serum ferritin (sFer), C-reactive protein (CRP), interleukin-6 (IL-6), hemoglobin (Hb), hematocrit (Ht), and serum hepcidin (sHep) were performed before surgery (Pre), and on postoperative days 3 (D3), 7 (D7), and 14 (D14).
The median values of sFe on Pre, D3, D7, and D14 were 73.0, 30.0, 33.0, and 41.0 microg/ dL, respectively (P < 0.05), and those of TIBC were 276.0, 160.0, 176.0, and 165.0 microg/ dL, respectively (P < 0.05). CRP and IL-6 became maximal on D3. The median values of sHep on Pre, D3, D7, and D14 were 18.9, 42.9, 25.7, and 21.2 mg/dL, respectively (P < 0.05). Hb and Ht reached minimum values on D3 and remained low until D14. The median values of sFer on Pre, D3, D7, and D14 were 135, 301, 267, and 233 ng/ dL, respectively.
Hepcidin production is increased after pancreatoduodenectomy. Because hepcidin is known to divert iron to storage-type ferritin rather than to erythropoiesis, iron administration intended for erythropoiesis during this period may be ineffective.

ABSTRACT: To investigate the protective effect of erythropoietin (Epo) against ischemia-reperfusion injury (IR/I) following the Pringle maneuver (PM), in comparison with conventional steroid administration in a prospective randomized trial.
Patients were randomized by age, sex, diagnosis, and surgical method, and assigned to three groups: (1) A steroid group (STRD, n = 9) who received 100 mg of hydrocortisone before PM, and on postoperative days 1, 2 and 3, followed by tapering until postoperative day 7; (2) An EPO1 group (n = 10) who received 30,000 U of Epo before the PM and at the end of surgery; and (3) An EPO2 group (n = 8) who received 60,000 U of Epo before the PM. Hemoglobin (Hb), hematocrit (Ht), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), lactate, interleukin-6 (IL-6), and tumor necrosis factor (TNF)-α were measured before and just after (Day 0) surgery, and on postoperative days 1, 3, 7 and 14.
There were no increases in Hb and Ht in the EPO1 and EPO2 groups. AST was significantly lower in EPO1 than in STRD on Day 0 (P = 0.041), and lower in EPO1 than in STRD and EPO2 on Day 1 (P = 0.018). ALT was significantly lower in EPO1 than in STRD and EPO2 on Day 0 (P = 0.020) and Day 1 (P = 0.004). There were no significant inter-group differences in the levels of LDH and lactate. IL-6 was significantly lower in EPO1 than in STRD and EPO2 on Day 0 (P = 0.0036) and Day 1 (P = 0.0451). TNF-α was significantly lower in EPO1 than in STRD and EPO2 on Day 0 (P = 0.0006) and Day 1 (P < 0.0001). Furthermore, hospitalization was significantly shorter in EPO1 and EPO2 than in STRD.
Epo has greater potential than steroids to ameliorate IR/I after the PM. Epo at a dose of 30,000 U, administered before PM and just after surgery, yields better results.

ABSTRACT: Intraoperative assessment of flow in the renal artery and vein after reconstruction is a crucial matter in kidney transplantation. Conventional Doppler ultrasound detects blood flow only in a limited area. The authors report a newly developed device that noninvasively visualizes the condition of perfusion of an entire allograft at one time from any angle and also clearly detects the state of anastomosis of the renal vessels. This near-infrared camera system provides the opportunity for the intraoperative assessment of the vasculature of renal allografts.

ABSTRACT: To evaluate the validity of the estimated glomerular filtration rate (eGFR) as a preoperative renal function parameter in patients with gastric cancer.
A retrospective study was conducted in 147 patients with gastric cancer. Preoperative creatinine clearance (Ccr), eGFR, and pre- and postoperative serum creatinine (sCr) data were examined. Preoperative Ccr and eGFR were then compared for their reliability in predicting postoperative renal dysfunction.
Among 110 patients with normal preoperative Ccr values, 7 (6.3%) had abnormal postoperative sCr values, and among 112 patients with normal preoperative eGFR values, postoperative sCr was abnormal in 5 (4.5%) (P = 0.53). Among 37 patients with abnormal preoperative Ccr values, 30 (81.1%) had normal postoperative sCr values, and of 35 patients with abnormal preoperative eGFR values, postoperative sCr was normal in 25 (71.4%) (P = 0.34). Preoperative Ccr was significantly correlated with eGFR (r = 0.514), and postoperative sCr was significantly correlated with preoperative Ccr (r = -0.334) and eGFR (r = -0.02).
Preoperative eGFR is as effective as Ccr for predicting postoperative renal dysfunction. eGFR should therefore be used as an indicator of preoperative renal function in place of Ccr since it is a cheaper and easier to perform test.

ABSTRACT: We analyzed the outcome of patients with advanced unresectable pancreatic cancer treated in our department from 2001 to 2008.
Of the 83 patients included in this study, 50 patients received single-agent treatment with gemcitabine (GEM), 9 patients GEM combined with radiotherapy (GEM+R) and 24 patients had best supportive care (BSC). We analyzed survival rates among the groups and risk factors for each group.
The 3-year survival rates were dismal: GEM group 2.9%, GEM+R group 0% and BSC group 0%. Significant prognostic factors of the study were: performance status (PS), response rate and decrease in the CA19-9 level. Significant prognostic factors by the Cox proportional hazard model were the albumin level prior to treatment, CA19-9 levels before treatment, decrease in CA19-9 and response rate. Albumin levels and the Glasgow Prognostic Score (GPS) were found to be factors affecting survival in the GEM group.
In this series of patients with unresectable pancreatic cancer, good PS, decrease in CA19-9 after treatment and good GPS determined prior to treatment were independent prognostic factors for better overall survival.

ABSTRACT: A retrospective study was conducted to compare measured creatinine clearance (Ccr) with estimated glomerular filtration rate (eGFR) as a preoperative renal function test in patients undergoing pancreatoduodenectomy.
The records of 139 patients undergoing pancreatoduodenectomy were enrolled, and preoperative Ccr, a 3-variable equation for eGFR (eGFR3) and a 5-variable equation for eGFR (eGFR5) were estimated. The maximum increases in the postoperative serum creatinine and urea nitrogen levels were compared between the groups with normal and abnormal levels relative to Ccr, eGFR3, and eGFR5.
There were 30 patients with abnormal Ccr levels, 17 with abnormal eGFR3 levels, and 16 with abnormal eGFR5 levels. Postoperative serum creatinine and urea nitrogen levels were significantly higher in patients with eGFR3 and eGFR5 abnormal levels than in patients with eGFR3 and eGFR5 normal levels. Postoperative serum creatinine and urea nitrogen levels tended to be higher in patients with Ccr abnormal level. The sensitivity and specificity of eGFR3 and eGFR5 for postoperative renal dysfunction were better than those of Ccr, and multivariate analysis showed that eGFR5 was the only independent predictive factor for postoperative renal dysfunction.
The eGFR5 and eGFR3, rather than the Ccr, are recommended as preoperative renal function test in patients undergoing pancreatoduodenectomy.
