Abstract
BACKGROUND Patient and staff cohorting is part of a bundle approach in the response to multi-drug-resistant organisms, but its effectiveness is not fully clarified. This study compared the risks of acquiring vancomycin-resistant Enterococcus faecium (VREfm) at a hospital during a VREfm outbreak based on contact characteristics in order to better understand the effectiveness of cohorting. METHODS Exposure came from contact with patients with VREfm (infectors), including existing patients with VREfm and patients who acquired VREfm during the study period. Contact was defined as length of contact time, degree of sharing space, and care by the same nurses as those caring for infectors between January and March 2018. The outcome was VREfm acquisition as determined through monthly stool or rectal screening cultures. Incidence rates were calculated based on contact patterns, and incidence rate ratios (IRRs) were compared. FINDINGS Among 272 inpatients (4038 patient-days), 43 patients acquired VREfm with the same or similar pulsotype. Incidence rates were 8.45 per 1000 patient-days when susceptible inpatients were on the same ward as an infector but cared for by different nurses (reference), 16.96 when susceptible inpatients were on the same ward as an infector and cared for by the same nurses [IRR 2.01, 95% confidence interval (CI) 0.62-10.28], and 52.91 when susceptible inpatients shared a room with an infector (IRR 6.26, 95% CI 1.61-35.40). CONCLUSION Compared with susceptible inpatients in a different room from infectors and not being cared for by the same nurses, the risk of VREfm acquisition could be six times higher for susceptible inpatients who are in the same room as infectors, and could be double for susceptible inpatients cared for by the same nurses as infectors.

Abstract
Percutaneous drainage catheters (PDCs) are required for the management of benign biliary strictures refractory to first-line endoscopic treatment. While biliary patency after PDC placement exceeds 75%, long-term catheterization is occasionally necessary. In this article, we assess the outcomes of patients at our institution who required long-term PDC placement.A single-institution retrospective analysis was performed on patients who required a PDC for 10 years or longer for the management of a benign biliary stricture. The primary outcome was uncomplicated drain management without infection or complication. Drain replacement was performed every 4 to 12 weeks as an outpatient procedure.Nine patients (three males and six females; age range of 48-96 years) required a long-term PDC; eight patients required the long-term PDC for an anastomotic stricture and one for iatrogenic bile duct stenosis. A long-term PDC was required for residual stenosis or patient refusal. Drain placement ranged from 157 to 408 months. In seven patients, intrahepatic stones developed, while in one patient each, intrahepatic cholangiocarcinoma or hepatocellular carcinoma occurred.Long-term PDC has a high rate of complications; therefore, to avoid the need for using long-term placement, careful observation or early surgical interventions are required.

Abstract
Hepatic epithelioid hemangioendothelioma (EHE) is a rare malignant tumor with unknown pathogenesis. Herein, we report a case of a hepatic EHE presenting synchronously with a hepatocellular carcinoma (HCC). To the best of our knowledge, this is the second case report of synchronous hepatic EHE and HCC. An 84-year-old man presented with back pain. During examination, a tumor in liver segment 3 was coincidentally detected. Tumor marker (carbohydrate antigen 19-9, alpha-fetoprotein, and protein induced by vitamin K absence or antagonist-II) levels were elevated. Contrast-enhanced computed tomography revealed perinodular enhancement in the arterial and portal phases. Another tumor was detected in liver segment 2, which was homogeneously enhanced in the arterial phase, followed by washout in the portal and late phases. Based on these imaging findings, we diagnosed the tumor in segment 3 as a solitary cholangiocellular carcinoma and the tumor in segment 2 as a solitary HCC. Lateral sectionectomy of the liver was performed. Microscopically, spindle-shaped and epithelioid cells were present in the tumor in segment 3. On immunohistochemistry, the tumor cells were positive for CD31 and CD34, focally positive for D2-40, and negative for AE1/AE3. Therefore, the tumor in segment 3 was ultimately diagnosed as an EHE and the tumor in segment 2 as a well-differentiated HCC. Preoperative diagnosis of EHE is difficult owing to the lack of specific findings. Intratumoral calcification, halo sign, and lollipop sign are occasionally found in EHE and are useful imaging findings for diagnosis. Clinical behavior is unpredictable, ranging from indolent growth to rapid progression. Clinical or pathological predictors of the course of EHE are urgently required.

Abstract
Background Pancreatic trauma is a rare condition with a wide presentation, ranging from hematoma or laceration without main pancreatic duct involvement, to massive destruction of the pancreatic head. The optimal diagnosis of pancreatic trauma and its management approaches are still under debate. The East Association of Surgery for Trauma (EAST) guidelines recommend operative management for high-grade pancreatic trauma; however, several reports have reported successful outcomes with nonoperative management (NOM) for grade III/IV pancreatic injuries. Herein, we report a case of grade IV pancreatic injury that was nonoperatively managed through endoscopic and percutaneous drainage. Case presentation A 47-year-old Japanese man was stabbed in the back with a knife; upon blood examination, both serum amylase and lipase levels were within normal limits. Contrast-enhanced computed tomography (CT) showed extravasation of the contrast medium around the pancreatic head and a hematoma behind the pancreas. Abdominal arterial angiography revealed a pseudo aneurysm in the inferior pancreatoduodenal artery, as well as extravasation of the contrast medium in that artery; coil embolization was thus performed. On day 12, CT revealed a wedge-shaped, low-density area in the pancreatic head, as well as consecutive pseudocysts behind the pancreas; thereafter, percutaneous drainage was performed via the stab wound. On day 22, contrast radiography through the percutaneous drain revealed the proximal and distal parts of the main pancreatic duct. The injury was thus diagnosed as a grade IV pancreatic injury based on the American Association for the Surgery of Trauma guidelines. On day 26, an endoscopic nasopancreatic drainage tube was inserted across the disruption; on day 38, contrast-enhanced CT showed a marked reduction in the fluid collection. Finally, on day 61, the patient was discharged. Conclusions Although the EAST guidelines recommend operative treatment for high-grade pancreatic trauma, NOM with appropriate drainage by endoscopic and/or percutaneous approaches may be a promising treatment for grade III or IV trauma.

Abstract
Background Reactive lymphoid hyperplasia (RLH) of the liver is a benign disorder. It is usually observed in the skin, orbit, thyroid, lung, breast, or gastrointestinal tract, but rarely in the liver. Since the first report of RLH of the liver in 1981, only 75 cases have been described in the past literature. Herein, we report a case of RLH of the liver in a patient with autoimmune hepatitis (AIH), which was misdiagnosed as hepatocellular carcinoma (HCC) preoperatively and resected laparoscopically. Case presentation A 43-year-old Japanese woman with autoimmune hepatitis was followed up for 5 years. During her medical checkup, a hypoechoic nodule in segment 6 of the liver was detected. The nodule had been gradually increasing in size for 4 years. Abdominal ultrasound (US) revealed a round, hypoechoic nodule, 12 mm in diameter. Contrast-enhanced computed tomography (CT) demonstrated that the nodule was slightly enhanced in the arterial dominant phase, followed by perinodular enhancement in the portal and late phases. A magnetic resonance imaging (MRI) scan showed low signal intensity on the T1-weighted image (T1WI) and slightly high signal intensity on the T2-weighted image (T2WI). The findings of the Gd-EOB-DTPA-enhanced MRI were similar to those of contrast-enhanced CT. Tumor markers were all within the normal range. The preoperative diagnosis was HCC and a laparoscopic right posterior sectionectomy was performed. Pathological examination revealed that the nodular lesion was infiltrated by small lymphocytes and plasma cells, and germinal centers were present. Immunohistochemistry was positive for B cell and T cell markers, indicating polyclonality. The final diagnosis was RLH of the liver. Conclusions The pathogenesis of RLH of the liver remains unknown, and a definitive diagnosis based on imaging findings is extremely difficult. If a small, solitary nodule is found in female patients with AIH, the possibility of RLH of the liver should be considered.

Abstract
This case pertained a 53-year-old man who underwent nab-PTX plus GEM therapy for BR-A pancreatic head cancer. He achieved a partial response and underwent pancreatoduodenectomy. Dynamic CT showed blockage of the original common hepatic artery branching from the celiac artery. Hepatic blood flow was maintained by a pancreatic arcade branching from the superior mesenteric artery which ran along the ventral side of the pancreatic head. The cancer had invaded the same location; therefore, the hepatic artery and portal vein were both resected and reconstructed. The patient had no complications, such as postoperative pancreatic fistula, and was discharged 45 days postoperatively. Currently(5 months postoperatively), postoperative S-1-based adjuvant chemotherapy is being administered, and the patient had a recurrence-free survival.

Abstract
BACKGROUND/AIM Neoplastic spindle cells (NSCs) are believed to play a role in cancer invasion and metastasis, as well as in poor prognosis. The clinicopathological characteristics and prognostic relevance of NSCs was investigated in gallbladder cancer. MATERIALS AND METHODS Specimens were obtained from 62 patients with gallbladder cancer who underwent surgery. The emergence of NSCs and their correlation with clinicopathological factors, prognosis, and EMT markers was evaluated. RESULTS The NSC grade correlated with tumor size, preoperative CA19-9, surgical margin, the degree of differentiation, the depth of invasion, lymph node metastasis, lymphatic invasion, vascular invasion, and perineural invasion. Multivariate analysis of overall survival showed that NSCs were an independent prognostic factor. A correlation between NSCs and EMT was also suggested. CONCLUSION NSCs are an independent prognostic factor for patients with postoperative gallbladder cancer, which also suggests a correlation between NSCs and EMT.

Abstract
BACKGROUND/AIM The aim of this study was to examine the clinicopathological features of intraductal papillary neoplasm of the bile duct (IPNB) and investigate their relationships with intraductal papillary mucinous neoplasm (IPMN). PATIENTS AND METHODS Our study included 104 patients who underwent resection of tumors that showed papillary growth within the bile duct and pancreas. RESULTS Comparisons were performed based on subtypes and histological grades. The presence of various histological grades was confirmed in both the IPNB group and the IPMN group, and statistical significance was found in the between-group comparisons of subtypes and histological grades. It was shown that while all patients who underwent IPNB resection did not match the classifications proposed by Nakanuma et al., they did reflect classification characteristics. CONCLUSION IPNB and IPMN have common clinical histological features. Common features between IPNB subtype classifications were also identified, which may provide novel diagnostics.

Abstract
BACKGROUND/AIM Intraductal papillary mucinous neoplasm (IPMN) has a variety of histological and morphological appearances. Matrix metalloproteinases (MMPs) have been considered to be associated with tumor progression or poor prognosis. The aim of this study was to elucidate the molecular basis of IPMN variation in different types of lesions. MATERIALS AND METHODS The expression of MMP-1,2,7,9 in 51 cases of IPMN were investigated. The MMP score was calculated as the sum of the score of staining distribution and the score of the intensity staining. RESULTS MMP scores were correlated with histological grade, histological subtype, and type of invasion. MMP high expression groups (MMP score ≥5) had worse prognosis than low-expression groups. CONCLUSION MMP expression varied between different types of IPMN, a result supporting differences in molecular basis of malignancies. These considerations may be helpful for optimal management or treatment according to various types of IPMN.

Abstract
BACKGROUND/AIM The aim of this study was to examine the clinicopathological features of pancreatic adenosquamous carcinoma (PASC). PATIENTS AND METHODS Our study included seven patients who underwent resection of PASC. RESULTS PASC is characterized by large tumors and strong infiltration into the major blood vessels and other organs, forcing many patients to undergo extended resections. In addition, all patients experienced liver metastasis recurrence following surgery, with a very poor prognosis. Histopathologically, a poorly differentiated sarcomatous component existed in all patients in addition to an adenocarcinoma component and squamous carcinoma component. Although P40 staining for the sarcomatous component was positive along with squamous carcinoma, E-cadherin expression disappeared while vimentin was expressed. It has been suggested that it is highly likely that these sarcomatous components are derived from squamous carcinoma and have an impact on prognosis. CONCLUSION The sarcomatous component may be related to the biological malignancy of PASC.

Abstract
Borderline resectable pancreatic head cancer (BR-PHC) has low resectability due to vascular invasion. Although the clinical effects of neoadjuvant chemoradiotherapy (NAC-RT) for BR-PHC have been examined, few studies have reported its pathological aspects. The present study retrospectively investigated the effect of NAC-RT on the histological features of BR-PHC. A total of 29 patients with BR-PHC who underwent NAC-RT, and 55 controls with resectable PHC, who underwent pancreaticoduodenectomy at the Kurume University Hospital. Tumor staging, lymphovascular invasion (LVI), and microvessel invasion (MVI) were evaluated. The median tumor size in the NAC-RT group was 2.0 cm, and it was smaller than that of the control group (P=0.006). The rates of lymph node metastasis, LVI, and MVI were significantly lower in the NAC-RT group (P<0.001, 0.002, and 0.015, respectively). Overall survival in the NAC-RT group was comparable to that in the control group, although patients with BR-PHC generally had a poorer prognosis than those with resectable PHC. Patients in the NAC-RT group without portal vein invasion (PVI) had a significantly better prognosis than those with PVI in the control group (P=0.002). NAC-RT may be beneficial for patients with BR-PHC by inhibiting local invasion and metastasis as prognosis following resection could be equivalent to that of patients with conventional ductal adenocarcinoma.

Abstract
Here, we report our experiences with 2 cases of afferent loop obstruction with percutaneous bowel drainage(PBD)and present a review of the literature. Case 1 involved a 60-year-old woman. She underwent pancreaticoduodenectomy for pancreatic cancer. Eighteen months postoperatively, a recurrence marked by a jejunal elevation and expansion on the cecal side near the porta hepatic lymph nodes appeared. We performed PBD because intestinal depression via the endoscopic approach was difficult. She was discharged from the hospital 7 days after PBD. Case 2 involved a 51-year-old woman. She underwent total gastrectomy and Roux-en-Y reconstruction for progressive stomach cancer. We detected a local recurrence in the Y anastomosis following a chief complaint of vomiting 10 months postoperatively. Fifteen months postoperatively, she developed acute pancreatitis with afferent loop syndrome. We performed PBD via a trans-liver route. The patient was discharged from the hospital 11 days after PBD. By devising a puncture route, we could safely perform PBD for an afferent loop obstruction.

Abstract
BACKGROUND We experienced a rare case of benign arterial stricture of the right posterior hepatic artery (RPHA) caused by atherosclerosis in a patient with hilar cholangiocarcinoma. CASE PRESENTATION A 75-year-old man was referred to our hospital for the detailed investigation of serum hepatobiliary enzyme elevation. The patient had a history of hypertension, type 2 diabetes mellitus, and an operative history of coronary artery bypass grafting 10 years before. Endoscopic retrograde cholangiography found strictures of the right and left hepatic ducts with involvement of right anterior and posterior bile ducts. Adenocarcinoma was evident by brush cytology. We diagnosed these findings as hilar cholangiocarcinoma and planned left trisectionectomy including bile duct reconstruction. Although the tumor and RPHA were not adjacent, preoperative multidetector computed tomography revealed a stricture of the RPHA that was 5.6 mm in length. We suspected that atherosclerosis caused the stricture, and we performed digital subtraction angiography and intravascular ultrasonography that showed stricture of the RPHA accompanied by thick plaques in the arterial wall. We placed a bare-metal stent in the RPHA and then performed left trisectionectomy. Since this patient developed bile leakage postoperatively, percutaneous drainage was performed. The bile leakage was successfully controlled, and the patient was discharged 3 months after surgery. Unfortunately, 4 months after hepatectomy, he was re-hospitalized with multiple pyogenic liver abscesses. We performed intensive multimodal treatment for the liver abscesses and stabilized the disease; however, we eventually lost this patient due to liver failure 14 months after surgery. CONCLUSION To the best of our knowledge, there is no previous literature on atherosclerosis of the RPHA, which was evident preoperatively in our case. Because arterial complications may lead to critical biliary complications in patients who undergo left trisectionectomy, we first performed prophylactic arterial stent placement. We speculate that existing chronic microscopic injury of the peribiliary plexus might have caused the liver abscesses. We successfully diagnosed atherosclerosis of the RPHA preoperatively. However, further investigation of patients is warranted to determine if left trisectionectomy is contraindicated in these patients.

Abstract
T2 (tumor invades perimuscular connective tissue; no extension beyond serosa or into liver) gallbladder cancer has generally been treated by S4aS5 subsegmentectomy (S4aS5 HR). We investigated the therapeutic effect of full-thickness cholecystectomy (FC) and gallbladder bed resection (GBR), in terms of tumor location and resection margin (distance from the tumor). At our department we employ the following protocol to determine the extent of resection needed to achieve R0 status: (1) A tumor located in the gallbladder fundus (Gf) or body (Gb) and only on the free peritoneal side was classified as P-type, for which full-thickness cholecystectomy and regional lymph node dissection were performed. (2) A tumor located in Gf or Gb and in contact with the liver bed was classified as H-type, for which gallbladder bed resection and regional lymph node dissection were performed. (3) A tumor located in the gallbladder neck (Gn) was classified as N-type, for which gallbladder bed resection, bile duct resection, and regional lymph node dissection were performed. Twenty-two patients admitted to our department between January 2000 and December 2014 with pT2gallbladder cancers were included in our study. Surgical procedures performed were compared with those specified in our protocol, and patients in whom the extent of resection was greater than that specified in our strategy were evaluated clinicopathologically and in terms of recurrence and the prognosis. Six (27.2%), 7 (31.8%), and 9 (40.9%) patients underwent limited, standard, and extended surgery, respectively. Ten (66.7%) of 15 patients with tumors close to the liver bed underwent cholecystectomy or extended surgery, 7 (85.7%) of 8 patients with tumors close to the bile duct underwent bile duct resection, and 16 (72.7%) of 22 patients underwent regional lymph node dissection. Recurrence at the bile duct resection margin, para-aortic lymph node metastasis, and hepatic metastasis occurred in 2, 1, and 3 patients, respectively. The 3-year survival rates (for patients including those dying of noncancer causes) were 50, 100, and 75% after limited, standard, and extended surgery, respectively. There was a significant difference in the survival rate of patients who underwent standard or extended surgery (P=0.0273). Favorable results were obtained in T2 gallbladder cancer patients without performing S4aS5 subsegmentectomy. Depending on the tumor location, neither full-thickness cholecystectomy nor gallbladder bed resection appeared to pose problems regarding recurrence or prognosis. In conclusion, surgical treatment based on our protocol, which aims to achieve the condition of R0, may result in a sufficient therapeutic effect.

Abstract
Needle tract implantation after percutaneous ethanol injection therapy(PEIT)for hepatocellular carcinoma(HCC)is rare. Surgical treatment of such HCC implants is still controversial. We herein report the case of a patient who underwent laparoscopic resection for peritoneal dissemination after PEIT. An 81-year-old man underwent PEIT for primary HCC at another hospital. Thereafter, percutaneous radiofrequency ablation(RFA)was performed twice for intrahepatic recurrence. After the second RFA, a mass lesion was detected at the subhepatic space on computed tomography(CT). We reevaluated the CT and diagnosed the patient with peritoneal dissemination after PEIT. Laparoscopic resection was performed. However, the patient developed recurrences at the thoracic wall and peritoneum 12 months after laparoscopic surgery. Those 2 tumors were resected, and he remains alive, approximately 30 months after the laparoscopic resection. Laparoscopic extirpation of tract seeding may provide better clinical outcomes in select patients.

Abstract
BACKGROUND Little is known about multidrug-resistant Pseudomonas aeruginosa (MDRP) outbreaks in long-term care facilities (LTCFs). AIM To describe an MDRP outbreak in an LTCF and to clarify risk factors for MDRP acquisition. METHODS Patients who were positive for MDRP at an LTCF from January 2013 to January 2014 were analysed. A descriptive analysis, a case-control study, and a microbiological analysis were performed. FINDINGS A total of 23 MDRP cases were identified, 16 of which were confirmed in sputum samples. Healthcare workers were observed violating hand hygiene procedures when performing oral, wound, and genital care. Nasogastric tube and oxygen mask use was associated with MDRP acquisition in the respiratory tract, which might have been confounded by poor hand hygiene. Sharing unhygienic devices, such as portable oral suction devices for oral care, and washing bottles and ointments for wound and genital care with inadequate disinfection could explain the transmission of MDRP in some cases. Isolates from 11 patients were found to be indistinguishable or closely related by pulsed-field gel electrophoresis and harbouring the blaGES-5 gene. Subsequent enhanced infection control measures were supported by nearby hospitals and a local public health centre. No additional cases were identified for a year after the last case occurred in January 2014. CONCLUSION An outbreak of MDRP with an antimicrobial resistance gene, blaGES-5, occurred in a Japanese LTCF. It was successfully controlled by enhanced infection control measures, which neighbouring hospitals and a local public health centre supported.

Abstract
PURPOSE To investigate the efficacy of the combination of ultrasound-guided rectus sheath (RS) and transversus abdominis plane (TAP) blocks compared with TAP or RS block alone in gynecological single-incision laparoscopic surgery (SILS). MATERIALS AND METHODS Bilateral TAP blocks (Group A, n = 12), TAP and RS blocks (Group B, n = 12), and RS blocks (Group C, n = 12) with 40 ml ropivacaine/patient were performed for ovarian tumor SILS. The analgesic effects were evaluated using a numerical rating scale (NRS) at zero, six, 12, 24, and 48 hours post-surgery. RESULTS Umbilical pain on completion of general anesthesia was significantly less frequent in Group B (1/12) than Group A (7/12) (p = 0.03). The postoperative NRS scores were significantly lower in Group B than Group A at zero (p = 0.02) and six (p = 0.03) hours and Group C at zero (p = 0.001), six (p = 0.02), and 12 (p = 0.004) hours. CONCLUSION The combination of RS and TAP blocks reduced early postoperative pain compared with RS or TAP block alone for gynecological SILS.

Abstract
A 69-year-old man underwent right hemicolectomy for ascending colon cancer with liver metastases. Postoperative systemic chemotherapy did not reduce the metastases, and therefore, hepatic arterial infusion chemotherapy (HAI) was administered. The metastases decreased in size after 26 rounds of therapy, and the patient underwent resection. He is recurrence-free 63 months after the primary operation. A 57-year-old man underwent Hartmann's operation for sigmoid colon cancer with liver metastases. He underwent hepatic left lobe resection after metastases reduction by systemic chemotherapy. However, multiple liver metastases were detected 2 months later. Because the disease progressed despite the administration of systemic chemotherapy, HAI was utilized instead. The metastases decreased in size remarkably, and resection was performed. The patient is surviving 52 months after the primary operation while being continuously treated with HAI, resection, and systemic chemotherapy for re-recurrence. HAI is a potential alternative treatment for patients with colorectal liver metastases resistant to systemic chemotherapy.

Abstract
The patient was a 64-year-old woman. She was referred to our institute because of a chief complaint of upper abdominal pain. Abdominal computed tomographic scan revealed a 35 mm hypovascular tumor in the pancreatic head and superior mesenteric vein (SMV), as well as thrombosis. We chose neoadjuvant chemoradiation therapy (NACRT) (S-1/RT, 50.4 Gy/28 Fr) and anticoagulants. After the treatment, the primary lesion showed a partial response, and the SMV thrombosis was reduced. We performed pancreaticoduodenectomy. Histopathological examination revealed no cancer cells in the pancreas. Pathological evaluation revealed grade Ⅳ tumor according to the Evans classification. The patient had had no recurrence for 10 months after the pancreaticoduodenectomy.

Abstract
The most suitable management of recurrent abdominal desmoid tumor is still unclear. A case of recurrent huge abdominal desmoid tumor successfully treated by hyperthermia therapy is described. A 63-year-old man was operated upon for desmoid tumor in the retroperitoneum involving pancreas, posterior wall of the stomach and transverse mesocolon in 2007. In 2008, the tumor recurred and could not be resected because of the patient refused the operation. Several therapies using tamoxifen, anastrozole, imatinib mesylate and radiotherapy were all ineffective. The tumor grew bigger and bigger during a treatment period. Finally, hyperthermia treatment was applied to the tumor. The size of the recurrent desmoid tumor reduced 75% by hyperthermia treatment for 46-month. Base on this experience, we recommend hyperthermia as the treatment for patients with recurrent abdominal desmoid tumor that several therapeutic strategies did not achieve a remarkable response.

Abstract
When surgery is selected to treat postoperative recurrent hilar cholangiocarcinoma in the intrapancreatic bile duct, attention should be paid to the following: 1 ) technical resectability of the lesion, 2) reconstruction, and 3) high risk of complications. Eight cases, including the present case, of pancreatoduodenectomy (PD) for postoperative recurrent hilar cholangiocarcinoma in the intrapancreatic bile duct have been reported thus far. In October 2009, a 73-year-old man noticed that his stools were gray and visited a physician. He was diagnosed with cholangiocarcinoma on close examination and underwent left hepatic and caudate lobectomy in January 2010. After the surgery, he was treated with TS-1 (80 mg) and followed up at the outpatient clinic of our hospital. In July 2013, he was diagnosed with cancer of the lower bile duct and was admitted for surgery. The first and second pathological findings were carcinoma of the bile duct and papillary adenocarcinoma, respectively. The findings from the immunostaining were also inconsistent. The histopathological examination result suggested multicentric recurrence. The surgery was highly invasive, increasing the patient's risk of complications, in addition to the presence of postoperative adhesion. Therefore, surgery may be an important option for cases of localized recurrence but not for multicentric recurrence.

Abstract
AIM: To review the usefulness of endoscopic biliary stenting for obstructive jaundice caused by hepatocellular carcinoma and identify problems that may need to be addressed.
METHODS: The study population consisted of 36 patients with obstructive jaundice caused by hepatocellular carcinoma (HCC) who underwent endoscopic biliary stenting (EBS) as the initial drainage procedure at our hospital. The EBS technical success rate and drainage success rate were assessed. Drainage was considered effective when the serum total bilirubin level decreased by 50% or more following the procedure compared to the pre-drainage value. Survival time after the procedure and patient background characteristics were assessed comparatively between the successful drainage group (group A) and the non-successful drainage group (group B). The EBS stent patency duration in the successful drainage group (group A) was also assessed.
RESULTS: The technical success rate was 100% for both the initial endoscopic nasobiliary drainage and EBS in all patients. Single stenting was placed in 21 patients and multiple stenting in the remaining 15 patients. The drainage successful rate was 75% and the median interval to successful drainage was 40 d (2-295 d). The median survival time was 150 d in group A and 22 d in group B, with the difference between the two groups being statistically significant (P < 0.0001). There were no statistically significant differences between the two groups with respect to patient background characteristics, background liver condition, or tumor factors; on the other hand, the two groups showed statistically significant differences in patients without a history of hepatectomy (P = 0.009) and those that received multiple stenting (P = 0.036). The median duration of stent patency was 43 d in group A (2-757 d). No early complications related to the EBS technique were encountered. Late complications occurred in 13 patients (36.1%), including stent occlusion in 7, infection in 3, and distal migration in 3.
CONCLUSION: EBS is recommended as the initial drainage procedure for obstructive jaundice caused by HCC, as it appears to contribute to prolongation of survival time.

Abstract
PURPOSE To evaluate the effectiveness of ultrasound-guided transversus abdominis plane (TAP) and rectus sheath (RS) blocks in pain management and recovery after gynecological single-incision laparoscopic surgery (SILS). MATERIALS AND METHODS Abilateral TAP block (Group A, n = 9), bilateral TAP and RS blocks (Group B, n = 10), and a bilateral RS block (Group C, n = 9) with 40 ml ropivacaine per patient were conducted in 28 patients undergoing SILS for ovarian tumors. A pain score and walking distance in a 6-minute walk test (6MWT) were examined. RESULTS Pain scores were significantly lower on postoperative day (POD) 3 than on POD 1 in Groups B (p = 0.03) and C (p = 0.02). The walking distance on POD 3 was comparable with that before surgery in Group C (p = 0.75), but shorter in Groups A (p = 0.004) and B (p = 0.02). CONCLUSIONS The RS block alone was the most effective in relieving pain and accelerating general recovery after gynecological SILS.

Abstract
The contrast harmonic imaging technique allows visualization of micro bubbles and has facilitated the detection of blood flow on contrast-enhanced ultrasonography (CE-US). In hypovascular tumors such as pancreatic cancer a hypoxic nutrition-deficient environment increases tumor malignancy. In this study, we investigated the relation between CE-US findings, intratumoral microvessel density (MVD), and pathological analysis in pancreatic cancer, and we also investigated the clinicopathological significance of CE-US.The subjects were 16 pancreatic cancer patients who underwent CE-US before surgery. A time-signal intensity curve (TIC) was prepared based on the region of interest (ROI) in the tumor on CE-US, and the signal intensity (SI) was defined as an increase from the value before contrast imaging to the maximum value. Regarding MVD, histological sections were stained with anti-CD34 and α-smooth muscle actin (α-SMA) antibodies, and double stained micro-blood vessels were counted. The correlation between SI and MVD was investigated. In addition, disease-free survival (DFS) was compared between the hypo (≤mean SI) and hyper (>mean SI) SI groups.SI in cancerous lesions was 54.6±42.9 dB (mean±SD), and MVD in cancerous lesions was 12.5±5.02 (mean±SD). A positive correlation was noted between the SI and MVD (r(2)=0.408, p=0.008). The median DFS were 212 and 606 days in the hypo and hyper SI groups, respectively, showing a significantly shorter DFS in the hypo SI group (P=0.003). No patient died of the primary disease during the follow-up period in the hyper SI group, and a maximum 47-month follow-up was possible. A positive correlation was noted between SI and MVD, indicating that MVD of pancreatic cancer could be evaluated using CE-US. We suggested that CE-US is a useful predictor of patient prognosis after pancreatic cancer surgery.

Abstract
We classified resected intraductal papillary mucinous neoplasms (IPMNs) into four subtypes (gastric, intestinal, pancreatobiliary and oncocytic) according to their morphological features and mucin expression, determined their clinicopathological characteristics and investigated the possibility of preoperatively diagnosing these subtypes. Sixty resected tumors, 4 preoperative tumor biopsies and 10 preoperative pancreatic juice cytology specimens were analyzed. The gastric and intestinal types accounted for the majority of IPMNs. Non-gastric type IPMNs were of high-grade malignancy. Many of the pancreatobiliary-type IPMNs were in an advanced stage and were associated with a poor prognosis. The results of mucin immunohistochemical staining of preoperative biopsy and surgically resected specimens were in agreement with each other, and in close agreement with those for pancreatic juice cytology specimens obtained from 10 patients during endoscopic retrograde cholangiopancreatography (ERCP). The immunostaining of preoperative biopsy specimens and ERCP-obtained pancreatic juice cytology specimens may be useful in the differential diagnosis of gastric and intestinal types of IPMN. If such techniques enable the preoperative diagnosis of IPMN subtypes, their use in combination with conventional preoperative imaging modalities may lead to surgical treatment best suited for the biological characteristics of the four subtypes.

Abstract
Intestinal malrotation is caused by a developmental anomaly of the embryonic intestine. Most cases develop in neonates, and development in adulthood is rare and difficult to diagnose before surgery. Pancreaticoduodenectomy was performed for cancer of the ampulla of Vater accompanied by incomplete fixation in a 63-year-old male patient. A branch of the superior mesenteric artery was present on the resection line and was deemed likely to cause circulatory disorder in the small intestine, and the duodenum and jejunum were covered with a membranous structure making dissection, anatomical identification, and jejunectomy difficult. Herein, we report the case with a review of the literature.

Abstract
UNLABELLED The success of biliary drainage in patients with liver metastases from colorectal cancer and obstructive jaundice influences its prognosis greatly. In this study, we report a retrospective evaluation of endoscopic retrograde biliary drainage in patients with liver metastases from colorectal cancer and obstructive jaundice. MATERIALS AND METHODS From April 2004 to December 2011, 9 patients with liver metastases from colorectal cancer and obstructive jaundice who underwent endoscopic biliary drainage were evaluated retrospectively. RESULTS The mean serum levels of total bilirubin, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase improved significantly after biliary drainage. The median survival time after biliary drainage was 133 days. Only 4 cases were able to resume chemotherapy after biliary drainage, and their prognosis was significantly better than patients who were not able to resume chemotherapy(p=0.014). DISCUSSION Endoscopic biliary drainage in patients with liver metastases from colorectal cancer and obstructive jaundice was effective, led to the resumption of chemotherapy, and improved prognosis. However, sufficient consideration of the patient's prognosis and performance status is required in order to perform biliary drainage.

Abstract
CONTEXT For the majority of patients, ductal adenocarcinoma of the pancreas remains a lethal disease. Currently, surgical extirpation for localized disease offers the only chance for long-term survival. CASE REPORT We report a patient who underwent successful resection of isolated lung metastasis occurring 13 years after pancreatic cancer resection. A 59-year-old woman underwent distal pancreatectomy for pancreatic cancer 13 years previously, followed by adjuvant chemotherapy, and was followed-up at the outpatient clinic of a local hospital. From around June 2010, she noticed bloody sputum, so she visited a local hospital. Since her chest X-ray and CT revealed a 1.5 cm mass shadow in the segment 10 of her right lung and she was referred to the Respiratory Disease Center of our hospital. As a result of through examinations, she was strongly suspected of having lung metastasis of pancreatic cancer, and underwent partial pneumonectomy. Postoperative histopathological examination of the resected specimen was consistent with lung metastasis of pancreatic cancer. She is still alive and currently receives third line of chemotherapy. CONCLUSION Patients who have achieved long-term survival after pancreatic cancer resection and can tolerate surgery may benefit from resection of a lung metastasis of pancreatic cancer in terms of survival, if it controls the metastasis.

Abstract
No consensus has been reached concerning the effects of preoperative immunonutrition in patients undergoing hepatectomy. We evaluated the effects of immunonutrition before hepatectomy on perioperative management. This study was performed as a randomized controlled trial. Patients expected to undergo segmentectomy or more extensive hepatectomy for liver tumors were randomized to immunonutrition (IM) and control (C) groups each consisting of 13 patients. The IM group was given 750 ml of IMPACT in addition to half-size hospital meals orally from 5 days before to the day before surgery, and the C group was given conventional hospital meals. The blood level of eicosapentaenoic acid was elevated preoperatively in all patients of the IM group. The white blood cell count and interleukin 6 levels, which are indices of postoperative inflammation, were significantly lower in the IM group. As regards liver function, postoperative increases in the aspartate aminotransferase and alanine aminotransaminase levels were slightly suppressed in the IM group. No significant difference was noted in postoperative complications or duration of postoperative hospital stay. In patients undergoing hepatectomy, preoperative immunonutrition reduced inflammation and protected against liver dysfunction.

Abstract
Prognosis of pancreas cancer is extremely poor. For unresectable pancreas cancer, there has not been an effective method of treating. In our institution, the mean survival time was 13 . 6 months for a chemoradiotherapy case that used gemcitabine (GEM), but was 7.3 months for a non-treatment case in locally advanced and metastatic pancreas cancer. This time, we experienced a good case for unresectable pancreas cancer treated with chemoradiotherapy using GEM/S-1 that clearly exhibited a decrease in tumor size by tumor marker.

Abstract
We schemed intraperitoneal gemcitabine (ipGEM) for reduction of peritoneal dissemination to three patients with unresectable and one patient with recurrent pancreatic cancer, followed by intraperitoneal catheter and subcutaneous port placement. Two locally advanced cases were performed for intra-operative radiotherapy, and one of 2 locally advanced cases was performed for gastrojejunostomy. And another locally advanced case had ileostomy. The recurrent case was resected for metastatic tumor of abdominal wall. In one of locally advanced cases, we couldn't perform ipGEM for progression of disease. In two remaining locally advanced cases, we could keep on doing ipGEM, and the patients did not experience with abdominal discomfort or hematological toxicity.

Abstract
The patient was a 62-year-old man who underwent distal pancreatectomy and partial resection of transverse colon with diagnosis of cystic tumor of pancreas tail in July 2006. In histology, the tumor was an invasive carcinoma derived from intraductal tumor. So, Chemotherapy using gemcitabine (GEM) was administered. Eleven months after the operation, abdominal contrast-enhanced CT showed a cystic tumor in the subdiaphragm and CEA increased to 15 .2 ng/mL. Combination chemotherapy using GEM and S-1 was administered under the diagnosis of peritoneal recurrence. CEA decreased to a normal level, but 19 months after the operation, CA19-9 increased to 187 .7 U/mL. Then, radiotherapy (a total of 40 Gy) was performed. Twenty two months after the radiotherapy, though chemotherapy using S-1 was continued, CA19-9 re- increased to 134 .2 U/mL. Abdominal contrast-enhanced CT and PET detected no other recurrent lesion. A tumor resection was performed in January 2010. In immunostaining MUC1(+), MUC2(-), MUC5AC(+), MUC6(+) and mucus expression forms as well as with previous specimen, and was diagnosed as recurrence of the invasive carcinoma derived from intraductal tumor.

Abstract
We aimed to assess hepatic histopathological responses to preoperative chemotherapy in patients with colorectal liver metastasis. We selected all patients(n=34)with colorectal liver metastases between September 2006 and March 2009. The preoperative chemotherapy group was significantly associated with tumor regression, inflammatory response, sinusoidal dilatation compared with non-chemotherapy group. There was no difference in the rate of postoperative complications and hospital stay. Prolonged preoperative systemic chemotherapy alters liver parenchyma, but it does not increase postoperative complications. This should be taken into consideration before deciding a major liver resection in patients who have received preoperative chemotherapy.

Abstract
Situs inversus totalis is a rare anatomic variant of a complete mirror-image transposition of the thoracic and abdominal viscera. The performance of a pancreaticoduodenectomy and distal pancreatectomy in patients with situs inversus totalis is both rare and challenging. We herein present two cases of pancreatic cancer with situs inversus totalis. The abdominal anatomy was preoperatively assessed by multidetectorrow computed tomography, three-dimensional reconstruction, and angiography. We herein report that a pancreaticoduodenectomy and distal pancreatectomy with standard regional lymphadenectomy are feasible in patients with situs inversus totalis. Due to the transposition of the viscera and major blood vessels in such cases, preoperative knowledge of the exact anatomy, mapping of anomalies, and meticulous forward planning are essential for performing these technically difficult and complex hepatobiliary-pancreatic surgeries.

Abstract
The patient was a 73-year-old man. In 2001, PPPD was performed. After confirmation of an expanded intrahepatic bile duct and anastomic stenosis in July 2005, PTBD was performed into the B3. Adenocarcinoma was detected with bile cytodiagnosis, and was diagnosed as a recurrence of the left bile-duct anastomotic site. Under the informed consent, chemo-radiotherapy was performed in addition to beam radiotherapy (30 Gy) in September 2005. Then we performed an intracavitary irradiation at 25 Gy. UFT (200 mg) was administered along with the radiation therapies. After that, an internal fistularization due to the T-tube was done. Liver metastasis was confirmed by abdominal CT in 2006. We started administering of GEM (600 mg/body) every other week after the recurrence of the bile duct cancer. The patient had survived for 24 months from the recurrence. We report a good result of the recurrent bile duct cancer treated with combined modality therapy.

Abstract
UNLABELLED This study is for chemoradiotherapy of unresectable and recurrent cholangiocarcinoma (CCC). SUBJECTS AND METHODS Between April 2005 and March 2007, 5 patients were evaluated for unresectable and recurrent CCC. All patients were performed percutaneous transhepatic biliary drainage (PTBD) and treated with chemoradiotherapy. The radiation method was an external beam radiotherapy (EBRT) and remote after loading system (RALS). The chemotherapy was 5-FU and gemcitabine by intravenous injection. RESULTS Three patients had unresectable and 2 had recurrent CCC. As for the side effects, 4 patients had a slight neutropenia and 1 had an uncontrollable gastric bleeding. No patient had cholangitis. The mean survival time for unresectable and recurrent CCC was 13.7 months and 17 months, respectively. CONCLUSIONS Our results indicated that chemoradiotherapy had been consistent with efficacy in patients with unresectable and recurrent CCC.

Abstract
BACKGROUND/PURPOSE Telomerase, an enzyme that prevents the loss of telomere regions consisting of TTAGGG repeats, which maintain the stability of cells, is considered to be involved in cell immortality and cancer growth. Recent genetic analysis has shown that the mRNA for the catalytic subunit of human telomerase reverse transcriptase (hTERT) is expressed in many cancer tissues. METHODS In this study, we measured hTERT mRNA levels in bile samples from patients with pancreatobiliary disease, and we combined the hTERT mRNA analysis with conventional cytology to achieve an accurate preoperative diagnosis. Bile samples were obtained from 19 patients with biliary tract cancer, 6 with gallbladder cancer, 10 with pancreatic cancer, 1 with gastric cancer, and 10 with benign disease. These samples were examined cytologically, and analyzed for hTERT mRNA levels. RESULTS The Combination of cytological examination and hTERT mRNA analysis achieved a positive rate of 78.9% in diagnosing biliary tract cancer, significantly improving the diagnostic accuracy over that for either method alone (P = 0.01). The diagnostic sensitivity for malignant disease was 66.6%, also significantly improving the diagnostic accuracy compared with either method alone (P = 0.001). CONCLUSIONS The combination of cytological examination and hTERT mRNA analysis appeared useful for the preoperative diagnosis of malignant biliary tract diseases, but was not superior to diagnostic imaging studies, and therefore remains an adjunct to cytological examination. Further studies should lead to improvements in the combination's diagnostic capabilities.

Abstract
Expression of CD56, also known as the neural cell adhesion molecule (NCAM), in the pancreatic ducts of chronic pancreatitis is considered to represent a regenerative process of the pancreatic duct system. CD56 expression was analyzed in 25 tissue samples of invasive ductal carcinoma without mixed ductal-endocrine carcinoma of the pancreas, and in the surrounding non-cancerous pancreatic tissue. CD56 expression was detected in intercalated ducts (ICDs) of lobules in the pancreatic parenchyma showing chronic inflammation close to the carcinoma, but not in the carcinoma itself, in all cases. CD56 showed strong, diffuse expression in the areas with severe inflammation, but expression was weak in ICDs where the inflammation was mild. We suggested that CD56 expression is degenerative process in pancreatic tissue with chronic inflammation, and that examination of CD56 expression may be helpful in the differentiation of atypical degenerative ducts from cancerous ducts.

Abstract
The patient was a 45-year-old man with a history of heavy drinking. A pseudocyst about 30 mm in diameter was found in the head of his pancreas. About four weeks later an upper abdominal mass, abdominal pain and obstructive jaundice were confirmed. Abdominal CT revealed that the cyst had increased in size to about 60 mm, compressing the lower common bile duct and the surrounding digestive tract. Therefore endoscopic ultrasonography-guided cystogastrostomy following percutaneous transhepatic biliary drainage (PTBD) was performed. Postoperatively, the cyst quickly decreased in size and jaundice improved. Because of persistent common bile duct stenosis, an endoscopic retrograde biliary stent was implanted. There has been no recurrence at ten months after the endoscopic therapy. While invasive surgery is generally employed in the treatment of pancreatic pseudocyst complicated by obstructive jaundice, EUS-guided cystogastrostomy appears to be a useful procedure, particularly when considering the relatively minor degree of surgical invasion.

Abstract
Accumulating evidence from both genetic and clinico-pharmacological studies suggests that D-serine, an endogenous coagonist to the NMDA subtype glutamate receptor, may be implicated in schizophrenia (SZ). Although an association of genes for D-serine degradation, such as D-amino acid oxidase and G72, has been reported, a role for D-serine in SZ has been unclear. In this study, we identify and characterize protein interacting with C-kinase (PICK1) as a protein interactor of the D-serine synthesizing enzyme, serine racemase (SR). The binding of endogenous PICK1 and SR requires the PDZ domain of PICK1. The gene coding for PICK1 is located at chromosome 22q13, a region frequently linked to SZ. In a case-control association study using well-characterized Japanese subjects, we observe an association of the PICK1 gene with SZ, which is more prominent in disorganized SZ. Our findings implicating PICK1 as a susceptibility gene for SZ are consistent with a role for D-serine in the disease.

Abstract
Learned helplessness rats are thought to be an animal model of depression. To study the role of synapse plasticity in depression, we examined the effects of learned helplessness and antidepressant treatments on synapsin I (a marker of presynaptic terminals), growth-associated protein-43 (GAP-43; a marker of growth cones), and microtubule-associated protein-2 (MAP-2; a marker of dendrites) in the hippocampus by immunolabeling. (1) Learned helplessness rats showed significant increases in the expression of synapsin I two days after the attainment of learned helplessness, and significant decreases in the protein expression eight days after the achievement of learned helplessness. Subchronic treatment of naïve rats with imipramine or fluvoxamine significantly decreased the expression of synapsin I. (2) Learned helplessness increased the expression of GAP-43 two days and eight days after learned helplessness training. Subchronic treatment of naïve rats with fluvoxamine but not imipramine showed a tendency to decrease the expression of synapsin I. (3) Learned helplessness rats showed increased expression of MAP-2 eight days after the attainment of learned helplessness. Naïve rats subchronically treated with imipramine showed a tendency toward increased expression of MAP-2, but those treated with fluvoxamine did not. These results indicate that the neuroplasticity-related proteins synapsin I, GAP-43, and MAP-2 may play a role in the pathophysiology of depression and the mechanisms of antidepressants.

Abstract
BACKGROUND Pancreatectomy is the best treatment for pancreatic cancer. However, there is a high risk of post-operative complications, such as local recurrence, metastatic lymphadenopathy, carcinomatosa peritonitis and liver metastasis. Presently, there is no significant treatment that has yet had a strong impact on recurrent pancreatic cancer. This study was conducted concerning recurrent pancreatic cancer with metastatic liver tumors after pancreatectomy. SUBJECTS AND METHODS Between April 1998 and March 2005, our institute treated recurrent pancreatic cancer patients with liver metastasis. This study consisted of groups who received therapy and those who did not, and their subsequent survival rate was also studied. RESULTS Nine cases had a recurrent pancreatic cancer with metastatic liver tumors. According to the treatment modality, the study population was classified into two groups: one group consisted of 4 patients with no treatment and the other group consisted of 5 patients who received treatment with gemcitabine (GEM). The mean survival rate for the group who received no treatment was 6.6 months. The mean survival rate for the group who received the treatment was 22.3 months. In addition, one year survival rate for those who received no treatment was 0%. The one year survival rate for those who received the treatment was 75%. The group with treatment showed better results in overall mean survival rates, as well as a higher one-year survival rate than the group with no treatment. The GEM administration included both intraarterial infusion and intravenous infusion. CONCLUSIONS Prolongation of the survival period was obtained by administration of GEM for recurrent pancreatic cancer with metastatic liver tumors and inoperable advanced pancreatic cancer. We attempted to utilize the active treatment for recurrent pancreatic cancer with metastatic liver tumors. Thus, it was indicated that the therapy can be effective against recurrent pancreatic cancer with metastatic liver tumors.

Abstract
A 73-year-old female with jaundice was referred to our department and admitted. Blood examination on admission showed an abnormal liver function and an increase in CA19-9. Ultrasonography of the abdomen revealed a well-delineated round mass in the middle bile duct. After admission, PTBD was performed, and a complete obstruction was observed in the middle bile duct. Cytological examination of the bile demonstrated adenocarcinoma. Based on these findings, a diagnosis of middle bile duct cancer was made. Because of delirium and frequent wandering during the night due to dementia, a radical operation was abandoned, and a non-covered stent was placed. However, since 1 week after insertion of a non-covered stent, contrast radiography showed tumor protrusion (rapid obstruction) in the stent, and a covered stent was placed in the stent. The stent was open for 486 days after stent re-insertion. PTBD was performed for re-obstruction, but she died 596 days after admission. In patients for whom surgery is impossible for reasons other than tumor factors, internal fistula construction using a metallic stent, which neither impairs QOL nor shorten survival, can be indicated.

Abstract
It is well documented that neurosteroids administered during the neonatal period influence the development of several brain systems. In our previous study, pregnenolone administered to rats during the neonatal period altered adenosinergic and dopaminergic functions in the striatum and cerebral cortex. The present study examined the effects of the treatment with pregnenolone and dehydroepiandrosterone (DHEA) from the postnatal day (P) 3-P7 on synapsin I (a marker for presynaptic terminals) and glial fibrillary acidic protein (GFAP: a marker for astroglia) levels in the hippocampus of Sprague-Dawley rats at 3 and 7 weeks of age. In addition, neuropeptide Y and dynorphin A immunoreactivity was measured. The administration of pregnenolone and DHEA to neonatal rats significantly altered the expression of synapsin I in the dentate gyrus and CA3 region at post-puberty but not at pre-puberty. A significantly greater expression of GFAP-immunoreactive astrocytes or processes was demonstrated in the pregnenolone- and DHEA-treated groups at both pre-puberty and post-puberty. A significant increase in the number and size of GFAP-immunoreactive astrocytes and in the extension of arborization was seen in the overall hippocampus. The number of neuropeptide Y-positive cells in the hilus region was also significantly increased in the neurosteroid-treated group at post-puberty. No differences were detected in dynorphin A immunoreactivity among the experimental groups. These results of this study suggest that pregnenolone and DHEA play an important role in the development of hippocampus.

Abstract
We encountered a hilar bile duct cancer patient with intestinal Behçet's disease who manifested various symptoms during a short period in the acute stage after liver resection. Under a diagnosis of hilar bile duct cancer, a 52-year-old Japanese male was referred and admitted to our hospital. Hepatectomy and resection of the extrahepatic bile duct were performed. During the postoperative course, a large number of painful aphthous ulcers developed in the oral mucosa, along with a genital ulcer. A deep excavation-type ulcer was confirmed by colonoscopy in the ileum on the orifice side. We administered colchicine and mesalazine. Thereafter, the patient was treated at the outpatient clinic. Recurrent localized hilar bile duct cancer developed, and the patient died about 8 months after surgery. We present the clinical details of this rare case of hilar bile duct cancer with intestinal Behçet's disease.

The patient was a 72-year-old woman who had been diagnosed with cholecystolithiasis and had undergone laparoscopic cholecystectomy. Since the postoperative pathologic diagnosis was a gallbladder cancer with a depth of wall penetration of subserosa, she was admitted to Kurume University Hospital for a second-look operation. After admission, abdominal angiography was performed with a right femoral arterial puncture. After the release of inguinal compression with a belt, chest pain and difficulty in breathing appeared. Despite her normal blood pressure, arterial blood gas analysis showed a PO2 of 74.7 mmHg and a PCO2 of 41.5 mmHg, representing a slight decrease in PO2. Chest X-rays showed an increased cardiothoracic ratio and decreased lucency in the left upper lung field. The electrocardiogram revealed atrial premature contraction. Cardiac ultrasound did not show expansion of the right heart and blood vessels or abnormal structures in the main pulmonary artery. Since lung perfusion scintigraphy revealed perfusion defects in the left upper to middle and right upper lung fields, acute pulmonary embolism was diagnosed, and oxygen inhalation, thrombolytic, and anticoagulant therapy were instituted immediately. The symptoms improved the following day, but 240,000 u/day of urokinase was administered for 5 days, and 1,500 u/day of heparin for 10 days. On lung perfusion scintigrams 6 days later, the defects had disappeared. Moreover, no definite abnormal shadows were noted on chest X-rays. Radical surgery for gallbladder cancer was performed 3 weeks later. Considering the possible development of pulmonary embolism, we felt the need for careful management if the patient is released from bed rest after abdominal angiography.
