Abstract
A 26-year-old man with left inguinal pain and frequent urination was examined. An abdominal ultrasound revealed a cystic lesion. In further examinations, CT and MRI showed a large cystic lesion of about 20 cm in size, connected to mesenteric- derived blood vessels. We suspected a huge mesenteric lymphangioma and decided to perform a laparotomy. A tumor was seen in the mesentery of the jejunum and adhered to the duodenum widely. The tumor could be removed safely without resection of the duodenum by first sucking the contents and shrinking the tumor. The final pathological diagnosis was mesenteric lymphangioma. Adult mesenteric lymphangiomas measuring larger than 20 cm are relatively rare. We review the case in the context of the relevant literature.

Abstract
Situs inversus totalis(SIT)is a rare congenital condition that causes complete transposition of thoracic and abdominal viscera. Due to associated anatomical abnormalities and low frequency, surgery for affected patients is considered to be difficult. A 72-year-old man was referred to our hospital with a chief complaint of narrow stools. The diagnosis was anal canal cancer(cT1bN0M0)accompanied by SIT. A trans-perineal minimally invasive surgical procedure with laparoscopic abdominoperineal resection(Tp-APR)was performed. When mobilizing the sigmoid colon, the surgeon changed their position in consideration of anatomical abnormalities. On the other hand, manipulation around the rectum was possible using the same technique as in patients with normal anatomy. The postoperative course was uneventful, and he had no recurrence 18 months after surgery. This is the first case that showed Tp-APR for anal canal cancer with SIT performed safely and feasibly. Preoperative simulation of associated abnormal anatomical structures is considered crucial for a case of SIT.

Abstract
A 36-year-old woman visited a previous doctor with lower abdominal pain and nausea. Her former doctor's upper gastrointestinal endoscopy and CT scan showed giant folds and wall thickening of the lower body of the stomach, and she was referred on suspicion of scirrhous gastric cancer. Similar findings were found on enhanced CT at our hospital. Endoscopic findings performed several days later showed red and thickened mucosa at the cardia, but no wall thickening and giant fold, and there were no findings suggestive of scirrhous gastric cancer. Biopsy showed no atypical cells, and a large number of eosinophils appeared in the lesion at the cardia. Eosinophilia and anisakis IgE antibody were positive and a diagnosis of gastric anisakiasis was made. She was eating grilled horse mackerel the day before her stomachache. At the same time, pruritus and edema around her right knee also appeared, and a dermatologist diagnosed her with anisakis-related eosinophil edema. One month later, CT scan and endoscopy were almost normal. A young woman referred on suspicion of scirrhous gastric cancer experienced a rare case diagnosed with gastric anisakiasis.

Abstract
A 75-year-old man underwent laparoscopic ileocecal and partial small bowel resections for the management of appendiceal cancer. The pathological diagnosis was cecal cancer(T4b[ileum, abdominal wall],N0[0/13], M0, pStage Ⅱc). After 4 months of surgery, he suddenly experienced abdominal pain and vomiting and was presented to our emergency room. He was diagnosed with bowel obstruction following which, conservative treatment was initiated through a nasogastric ileus tube implantation; however, he did not show any improvement. Subsequently, he underwent experimental laparotomy on the 18th day of the disease. Intraabdominal examination revealed herniated small intestine through a mesenteric defect, which was closed following repositioning of the herniated small intestine. The postoperative course was good, and the patient was discharged on the 10th day after surgery. No recurrence of intestinal obstruction has been observed after 1 year and 6 months. Closure of the mesenteric defect, although not commonly performed in laparoscopic colorectal surgery, is worth considering because of the risk of developing an internal hernia requiring surgical treatment, as in our case.

Abstract
This study reports a 66-year-old female presenting abdominal pain. Gastrointestinal endoscopy showed the presence of a type 3 tumor in the lesser curvature of the stomach, and biopsy revealed poorly differentiated adenocarcinoma. CT images displayed thickening of the stomach wall and enlarged paraaortic lymph nodes, left supraclavicular lymph nodes, and left iliac lymph nodes. FDG-PET/CT scan showed abnormal accumulation at the same site. The patient was diagnosed with unresectable highly advanced gastric cancer(cT4aN2H0P0M1[LYM], Stage Ⅳ). She was treated with combination chemotherapy of S-1 and CDDP(SP). Tumor markers normalized(CA19-9 11,158→20 U/mL)after 3 courses with a marked reduction of lesions. After 5 courses of chemotherapy, the tissue biopsy did not reveal any cancer and a complete response(CR) was achieved. Adverse events of diarrhea and loss of appetite were observed. Subsequently, chemotherapy was discontinued after 6 courses, and CR remained for the next 5 years. Thus, we experienced a rare case of unresectable advanced gastric cancer with distant lymph nodes metastasis, showing long-term recurrence-free survival after receiving 6 courses of SP chemotherapy.

Abstract
A 67-year-old woman reporting lower abdominal pain and anemia was examined. Small intestinal tumor was diagnosed by small intestinal radiographic contrast study and small intestinal endoscopy, and we decided to perform a laparoscopic partial resection of the small bowel. Since she was obese patients(BMI 36.3, abdominal wall 6 cm)at high risk of postoperative incisional hernia, we devised a way to make the wound smaller. We judged thick abdominal wall make umbilical wound larger in single port surgery. We performed multi-port surgery by using one 15 mm trocar, and removed small intestinal tumor from 15 mm port incision. In addition, to prevent incisional hernia, we used a trocar with a wound closure assist function for securely closing the port wound in all layers. Histopathological diagnosis was neuroendocrine tumor. The patient is being followed up without recurrence and without incisional hernia. In partial small bowel resection of obese patient, the use of a 15 mm port to minimize wound site and the use of trocar with a wound closure assist function may lead to prevent incisional hernia.

Abstract
It is well known that black and green tea extracts, particularly polyphenols, have antimicrobial activity against various pathogenic microbes including viruses. However, there is limited data on the antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which emerged rapidly in China in late 2019 and which has been responsible for coronavirus disease 2019 (COVID‐19) pandemic globally. In this study, 20 compounds and three extracts were obtained from black and green tea and found that three tea extracts showed significant antiviral activity against SARS‐CoV‐2, whereby the viral titre decreased about 5 logs TCID50 per ml by 1·375 mg ml−1 black tea extract and two‐fold diluted tea bag infusion obtained from black tea when incubated at 25°C for 10 s. However, when concentrations of black and green tea extracts were equally adjusted to 344 µg ml−1, green tea extracts showed more antiviral activity against SARS‐CoV‐2. This simple and highly respected beverage may be a cheap and widely acceptable means to reduce SARS‐CoV‐2 viral burden in the mouth and upper gastrointestinal and respiratory tracts in developed as well as developing countries.

Abstract
BACKGROUND A new coronavirus (SARS-CoV-2) abruptly emerged in Wuhan, China, in 2019 and rapidly spread globally to cause the COVID-19 pandemic. AIM To examine the anti-SARS-CoV-2 activity of the potent disinfectant Cleverin, the major disinfecting component of which is chlorine dioxide (ClO2); and to compare the results with that of sodium hypochlorite in the presence or absence of 0.5% or 1.0% foetal bovine serum (FBS). METHODS Concentrated SARS-CoV-2 viruses were treated with various concentrations of ClO2 and sodium hypochlorite and 50% tissue culture infective dose was calcurated to evaluate the antiviral activity of each chemical. FINDINGS When SARS-CoV-2 viruses were treated with 0.8 ppm ClO2 or sodium hypochlorite, viral titre was decreased only by 1 log10 TCID50/mL in 3 min. However, the viral titre was decreased by more than 4 log10 TCID50/mL when treated with 80 ppm of each chemical for 10 s regardless of presence or absence of FBS. It should be emphasized that treatment with 24 ppm of ClO2 inactivated more than 99.99% SARS-CoV-2 within 10 s or 99.99% SARS-CoV-2 in 1 min in the presence of 0.5% or 1.0% FBS, respectively. By contrast, 24 ppm of sodium hypochlorite inactivated only 99% or 90% SARS-CoV-2 in 3 min under similar conditions. Notably, except for ClO2, the other components of Cleverin such as sodium chlorite, decaglycerol monolaurate, and silicone showed no significant antiviral activity. CONCLUSION Altogether, the results strongly suggest that although ClO2 and sodium hypochlorite are strong antiviral agents in absence of organic matter but in presence of organic matter, ClO2 is a more potent antiviral agent against SARS-CoV-2 than sodium hypochlorite.

Abstract
The patient is 77-year-old man. He received open cholecystectomy and choledocholithotomy when he was 74 years old. Because postoperative diagnosis was small cell neuroendocrine carcinoma(NEC), the resection of gallbladder bed and hilus lymph nodes were performed. During the follow up period, the liver metastases and portal vein tumor thrombosis appeared. Therefore, chemotherapy was performed according to small cell lung cancer. In addition to chemotherapy, radiation therapy was performed for the purpose of local control. He is still alive about 3 years after the first operation. This case suggested the efficacy of multidisciplinary treatment including operation, chemotherapy, and radiation therapy in NEC of gallbladder patient with liver metastasis.

Abstract
We report a rare case of hepatic fibrolamellar hepatocellular carcinoma(FLC). A 25-year-old Vietnamese male experienced loss of appetite and abdominal pain. He was referred for further examination of a 20 cm tumor in the left lobe of the liver detected in mass screening ultrasonography. He tested negative for HBs-antigen and HCV-antibody. The serum PIVKA- Ⅱ level was elevated. Liver function test findings were normal. The arterial phase of contrast enhanced abdominal CT revealed a 20×30 cm tumor that was well-enhanced, except for a central scar in the left lobe of liver. Enhanced MRI showed a high intensity tumor. T2-weighted MRI showed an iso-intensity tumor with a low-intensity central fibrous scar. Upon diagnosing the patient with FLC, we performed left hepatic trisegmentectomy. Pathological findings of the surgical specimen showed eosinophilic large neoplastic cells surrounded by fibrous stroma arranged in a lamellar fashion. This confirmed the diagnosis. FLC, which occurs in noncirrhotic livers of young patients, is a distinct clinicopathological variant of hepatocellular carcinoma. Hepatectomy for FLC should be accompanied with regional lymphadenectomy because of its association with lymph node metastasis. We also reviewed cases reported in Japan.

Abstract
A 72-year-old woman was transferred to our hospital after being diagnosed with retroperitoneal and ovarian tumors. Abdominal computed tomography revealed a well-defined mass lesion measuring 35 mm on the dorsal side of the descending part of the duodenum that was surrounded by the head of the pancreas and inferior vena cava. In addition, a cystic mass measuring 90 mm was found in the pelvis. Hence, the patient was diagnosed synchronous retroperitoneal tumor and teratoma. Laparoscopic retroperitoneal tumor resection and right adnexectomy were performed. The pathological findings indicated that the retroperitoneal tumor was a diffuse large B-cell lymphoma and the pelvic tumor was a mature cystic teratoma of the ovary. On the basis of the computed tomography findings, we judged that the tumor had a poor tendency to infiltrate and could be peeled off and resected using laparoscopic surgery. In this rare case, the retroperitoneal tumor and mature teratocarcinoma were simultaneously resected laparoscopically.

Abstract
A 59-year-old man visited our department because of cholecystectomy. Preoperative CT revealed a tumor shadow measuring 50 mm in front of the right iliopsoas muscle. MRI showed a low signal intensity on T1-weighted images and a slightly high signal intensity on the T2-weighted image. PET-CT showed accumulation of FDG(SUVmax 5.39)in the tumor but no other abnormal accumulations. We performed tumor resection for diagnostic purposes because malignancy could not be ruled out owing to the large size of the mass. Intraoperative findings showed a well-circumscribed margin of the tumor without invasion to other tissues. The retroperitoneum was incised circumferentially along the tumor under laparoscopic guidance, and the tumor was resected. Histopathological and immunostaining findings were consistent with leiomyosarcoma. In laparoscopic surgery, the surgical margin is observed in detail through the magnifying effect. Therefore, laparoscopic surgery can be a surgical option for tumors that may be completely excised based on preoperative findings.

Abstract
Intrahepatic bile duct dilatation was detected in a 63-year-old man based on abdominal ultrasonography. The computed tomography and magnetic resonance imaging scans showed an intrahepatic cystic lesion in the hilar bile duct that led to intrahepatic bile duct dilatation. As a result, intraductal papillary neoplasm of the bile duct(IPNB)was suspected. Moreover, the intrahepatic bile duct dilatation was confirmed by endoscopic retrograde cholangiopancreatography(ERCP). Biliary and brushing cytology indicated that the cystic lesion was class Ⅱ and class Ⅲ, respectively. Radiological imaging test did not rule out the possibility of a malignant lesion. Hence, a radical left hepatectomy was performed. Histopathological examination of the resected specimen indicated that it was a non-malignant cystic biliary hamartoma. Cystic biliary hamartoma or the von Meyenburg complex is a relatively rare disease. Although this disease is categorized as benign, differential diagnosis between benign and malignant forms is difficult, and this is an important clinical issue.

Abstract
A colonoscopy to investigate fecal incontinence revealed a type 3 tumor in the rectum of a 67-year-old man. Histological findings demonstrated rectal adenocarcinoma. CT revealed multiple metastases in the liver, and the patient was diagnosed as having rectal cancer(Rb, Ant, type 3, T3, N3, M1a[H2], cStage Ⅳa). No intestinal stenosis due to the tumor was found, and chemotherapy(FOLFIRI plus bevacizumab)was initiated. After 5 courses of the chemotherapy, a thrombus was found in the superior mesenteric vein on enhanced CT. The patient had no subjective symptoms, and anticoagulation therapy was started after admission. After confirming the shrinkage of the thrombus, laparoscopic abdominoperineal resection(prxD3)was performed to remove the primary tumor. The thrombus did not grow during the perioperative time and disappeared after 6 months. For the next 2 years, no new thrombus was detected. Mesenteric vein thrombosis is a notable complication of chemotherapy with bevacizumab.

Abstract
A 69-year-old man underwent a Miles operation with D3 lymph node dissection for rectal cancer. The pathological diagnosis was adenocarcinoma(Rb, A, ly2, v3, N2M0P0H0, Stage Ⅲb). Adjuvant chemotherapy was added for 6 months after the rectal resection. Metastasis in the left lung was detected 1 year and 10 months after rectal resection for which large segmental resection was performed. Without the onset of any new lesions, the patient underwent subsequent follow-up examinations. Abdominal CT performed for increased tumor marker levels observed at 6 years and 8 months after rectal resection revealed a mass suggestive of pancreatic ductal adenocarcinoma for which distal pancreatectomy was performed. The pathological diagnosis was metastasis to the pancreas from the rectal cancer as the tumor cells were immunohistochemically negative for cytokeratin 7 and positive for cytokeratin 20. There has been no indication of recurrence for 13 months after the pancreatic surgery. Resectable pancreatic metastasis from colorectal cancer is rarely reported. However, pancreatic resection may result in long-term survival in some cases. Patients that tolerate pancreatectomy and have no metastasis in the other organs should be considered good candidates for pancreatic resection. We present this case with a review of the literature.

Abstract
A 65-year-old man was diagnosed with agammaglobulinemia at the age of 53 years. To investigate the cause of the increased CRP value, CT was performed and revealed thickening of the walls of the ascending colon and rectum. Colonoscopy revealed tumors and stenoses in the ascending colon and rectum. Both tumors were found to be adenocarcinomas in histological examinations. The preoperative diagnosis of the ascending colon and rectal cancers was cT4aN0M0, cStageⅡb. Preoperatively, we administered 10.0 g of immunoglobulin intravenously. We performed laparoscopic right hemicolectomy and high anterior resection with D3 dissection of the lymph node. On postoperative day 1, we again administered 10.0 g of immunoglobulin intravenously. The patient recovered uneventfully and was discharged on postoperative day 13. Laparoscopic colectomy for patients with agammaglobulinemia can be performed safely by administering immunoglobulin during the perioperative period.

Abstract
We report a patient who had Castleman's disease with lymphadenopathy during the treatment of gastric cancer. In May 2017, a 63-year-old man underwent gastrointestinal endoscopy, which revealed a tumor on the posterior wall of the lower part of the stomach. Based on a biopsy, he was diagnosed with suspected adenocarcinoma, Group 4. In June 2017, he visited our hospital, and endoscopic submucosal dissection(ESD)was performed. The pathological diagnosis of the resected specimens was L, Less, 20×10 mm, Type 0-Ⅱc, tub1, pT1a(M), UL(-), ly(-), v(-), pHM0, pVM0, pStage ⅠA. He was referred to our department for the treatment of abdominal lymphadenopathy. His lymphadenopathy was localized in the gastric lesser curvature as an enlarged lymph node 15mm in size, based on the findings of contrast-enhanced CT. On FDG- PET/CT, we found a slight accumulation of SUVmax 2.4 in the early phase in the same lymph node. We could not confirm a diagnosis, and we performed laparoscopic dissection of the lymph node for diagnosis and treatment. The size of the specimen was 14×14mm, surface was smooth, and lymph node was elastic and soft. We found lymphoid follicles with atrophic germinal center using HE staining. We also found increased hyperplastic blood vessels around the germinal center, and he was diagnosed with hypervascular Castleman's disease.

Abstract
A 66-year-old man underwent total gastrectomy for gastric cancer. S-1 was administered as adjuvant chemotherapy. Abdominal CT showed para-aortic lymph node recurrence 31 months after the surgery. There was no other recurrence according to PET-CT, and we performed para-aortic lymph nodes dissection 41 months after the surgery. Lymph node recurrence in the retrocrural space was observed 37 months after the 2nd surgery. We administered S-1 plus L-OHP chemotherapy. After 4 courses, CT revealed that he had achieved complete response, and he has remained disease-free for 79 months after lymph node dissection. Some patients with para-aortic lymph node recurrence after curative gastrectomy may benefit from treatment including chemotherapy and surgical dissection.

Abstract
Metastasis of renal cell carcinoma to the pancreas is a relatively rare condition. We encountered 2 such cases. The first case was a 72-year-old man who underwent a left nephrectomy owing to left renal cancer in 2005. An abdominal dynamic CT scan 12 years after surgery revealed tumors in the pancreatic body and right kidney. A PET-CT scan revealed low intensity uptake of both tumors, and therefore, metastasis of the left renal cell carcinoma to the pancreas was suspected. We then performed partial resections of the pancreatic tail and right kidney. Pathologic findings confirmed that the pancreatic tumor and right renal tumor were metastases of the left renal cell carcinoma. The postoperative course was favorable, and the patient has been followed up in an outpatient setting for 10 months with no signs of recurrence. The second case was a 51- year-old woman with tumors in the left kidney and pancreatic head that were detected by abdominal contrast CT and MRI. We diagnosed the patient with left renal cell carcinoma with metastasis to the pancreas. We performed a radical nephrectomy of the left kidney and full pancreatectomy. Pathologic findings confirmed left renal cell carcinoma, pStage Ⅳ, with metastasis to the pancreas. The postoperative course was favorable without recurrence for 14 years. We report on two cases of metastasis of renal cell carcinoma to the pancreas in patients who underwent radical resections and had favorable postoperative courses, with some bibliographic consideration.

Abstract
The patient was a 79-year-old man. He underwent endoscopic papillectomy for ampullary cancer when he was 70 years old. At the ages of 71 and 73 years, liver metastasis in segment 6 was detected, and radiofrequency ablation(RFA)was performed and adjuvant chemotherapy(gemcitabine, S-1)was administered. At the age of 79 years, recurrence of liver metastasis appeared. Because there were no other metastatic lesions, we performed S6 subsegmentectomy. Five months after the surgery, no recurrence was observed. In general, the prognosis of patients with ampullary cancer with distant metastasis is very poor. This case suggested the efficacy of multidisciplinary treatment, including surgery, RFA, and chemotherapy, in a patient with ampullary cancer with distant metastasis.

Abstract
A 67-year-old woman was diagnosed with rectal cancer using colonoscopy. Computed tomography revealed the so-called superior mesenteric vein rotation sign, and intestinal malrotation was suspected. We planned chemotherapy after the surgical resection of the primary cancer because she had multiple lung metastases. Laparoscopic high anterior resection with D3 dissection of lymph nodes was performed. Intraoperative findings showed a non-rotation type intestinal malrotation and severe intra-abdominal adhesion. However, careful releasing operation enabled the typical approach of laparoscopic surgery for rectal cancer. The postoperative course was generally good, and she was discharged on the 17th postoperative day. The pathological diagnosis was rectal cancer(T3, N0, M1a, pStage Ⅳ). In laparoscopic surgery for colorectal cancer with intestinal malrotation, determining the anatomy of blood vessels and the site of the tumor before surgery is important. Furthermore, awareness that some cases have severe intra-abdominal adhesions even without a history of laparotomy is necessary.

Abstract
We report a patient with brain metastasis of rectal cancer who underwent metastatic tumor resection 3 times. In March 2012, a 76-years-old man, diagnosed with Stage III a rectal cancer, underwent Hartmann's operation. The lung metastasis was confirmed in July and November 2013, surgical resection for pulmonary metastasis was performed 2 times. In January 2016, he had difficulty of speaking, and isolated brain tumor was found. We performed surgical resection of brain metastasis in February 2016. In March and July 2016, the gamma knife radiosurgery was performed for other brain metastasis. In July 2016, he occurred nausea, headache and right identity hemi-blindness. Two new brain tumors were revealed. We performed surgical resection again. Three months after second brain surgery, he had dysarthria and a solitary brain tumor was confirmed. We performed third neurosurgical resection. All tumors of brain were found to be metastasis from rectal cancer in histological study. Currently, 16 months have passed since the first diagnosis of brain metastasis of this patient, and the quality of life was good relatively. The prognosis of the patients with brain metastasis is poor generally. However, this case suggested that multiple surgical resection of brain metastasis could improve prognosis and quality of life of patients. Accumulation of further cases is needed.

Impact of endoscopic stent insertion on detection of viable circulating tumor cells from obstructive colorectal cancer. Oncol Lett 2017; 15:400-406.

Abstract
The placement of a self-expanding metallic stent (SEMS) in obstructive colorectal cancer (OCRC) is acknowledged to be a safe and effective procedure for the relief of obstruction. However, there is concern that shear forces acting on the tumor during stent expansion may release cancer cells into the circulation, resulting in a poor prognosis. The aim of the present study was to determine whether colonic stent insertion increases viable circulating tumor cells (v-CTCs). A telomerase-specific replication-selective adenovirus-expressing GFP (TelomeScanF35) detection system was used to detect v-CTCs in 8 OCRC patients with a SEMS before and after stent insertion and after surgical resection. In 7 patients, a SEMS was inserted as a bridge to surgery (BTS), and in one patient, a SEMS was inserted for palliation. Surgical resection (R0) was performed in 7 patients. Four patients had no v-CTCs before SEMS placement, two of four measurable patients had an increased number of v-CTCs after SEMS placement (1-3 v-CTCs), and one of two patients with increased v-CTCs developed distant lymphatic metastasis despite curative resection. Four patients had v-CTCs (1-19 cells) before SEMS placement, and two of these four patients had an increase in the number of v-CTCs (20-21 cells) after SEMS placement, while one of the four patients died early with distant metastasis. The present study demonstrated that endoscopic stent insertion for OCRC may result in tumor cell dissemination into the peripheral circulation and may induce distant metastases.

Abstract
We report 2 resected cases of patients with non-isolated splenic metastasis of colon cancer. Case 1: A 67-year-old man who underwent partial transverse colectomy and partial hepatectomy for transverse colon cancer and liver metastasis. Approximately 18 months after the operation, splenectomy and partial hepatectomy were performed for metastasis to the spleen and liver. After partial hepatectomy for another recurrence, no signs of new recurrence have been observed for 42 months after splenectomy. Case 2: A 53-year-old woman who presented with bloating. CT and MRI scans revealed masses of the ileocecum, both ovaries, and spleen. We performed right hemicolectomy, total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy, para-aortic lymphadenectomy, omentectomy, and splenectomy. Histological findings showed cecal cancer metastasizing to the bilateral ovaries and spleen. Metastatic splenic tumor is relatively rare(0.3-7.3%). Splenectomy was reported to be an effective treatment modality for isolated splenic metastasis, while that for non-isolated metastasis is uncertain. Surgical resection should be considered even in non-isolated splenic metastasis cases because of the evidence of long-term survival in case 1.

Abstract
A 70-year-old man was referred to our hospital and admitted after abdominal computed tomography(CT)examination revealed a tumor in the retroperitoneum. The specific blood test findings were poor, and surveillance CT demonstrated a wellcircumscribed, enhanced mass measuring 40mm with calcification behind the horizontal portion of the duodenum. The tumor presented with a slightly high signal in low signal, T2 in T1, and it showed a diffusion decrease in DWI; the simple abdominal MRIrevealed heterogeneous accumulation of SUVmax 3.0 only for the lesion in FDG/PET-CT. Specific findings did not lead to a diagnosis, although EUS-FNA lower aspiration biopsy cytology was performed. Laparoscopic tumorectomy was performed to help determine the treatment strategy. Histopathological examination indicated that the tumor was composed of multiple lymph follicles with concentric layers of mantle zone cells, showing an onion skin-like lesion and atrophic germinal centers. The germinal centers had penetrating arterioles with hyalinized vessel walls, and Castleman's disease(hyaline vascular type)was therefore diagnosed. In this case, it was difficult to diagnose Castleman's disease before surgery. Surgical excision is a diagnostic as well as a curative method for management of this disease.

Abstract
A 65-year-old woman had received chemotherapy for malignant lymphoma since 2011. After the 8th course, computed tomography revealed the disappearance of lymph node metastasis, except for 22mm of the mass located on the tail side of the antrum. MRI showed a low intensity mass on the T1 and T2-weighted images. FDG-PET did not show abnormal uptake in the tumor. EUS-FNA did not reveal a definitive diagnosis. We performed a laparotomy for diagnosis and treatment. Intraoperative findings showed that the tumor occurred in the mesentery of the transverse colon. The pathological diagnosis was angiomyolipoma. The patient has been free from recurrent disease for 2 years and 6 months. Angiomyolipoma originating in the transverse mesentery region is rare and, due to various percentage of tissue factors, there are no fixed view of image findings. Furthermore, a large tissue volume is need for histological diagnosis. Laparotomy is useful for diagnosis and therapy for angiomyolipoma occurring in the mesentery of the transverse colon.

Abstract
Gastric cancer with portal tumor embolus is rare and there is no definite strategy for its surgical resection. We report 2 cases ofgastric cancer with portal vein tumor embolus treated using gastrectomy and thrombectomy. Case 1: The patient was a 56- year-old man. We performed total gastrectomy, distal pancreatectomy, splenectomy, and thrombectomy. The patient was treated with 4 courses ofS -1 plus CDDP chemotherapy followed by S-1 administration. Eight months after surgery, CT revealed metastasis in the left adrenal gland and he died 2 years after surgery. Case 2: The patient was a 57-year-old man. We performed total gastrectomy, distal pancreatectomy, splenectomy, partial resection of the transverse colon, and thrombectomy. The patient was treated using adjuvant S-1 chemotherapy followed by UFT administration for 3 years. The patient has been alive with no tumor recurrence for the past 10 years. If there is no other therapeutic option for portal vein embolus, gastrectomy with thrombectomy could increase the possibility oflong -term survival.

Abstract
A 67-year-old woman, who was diagnosed with ovarian cancer with multiple metastases, underwent abdominal total hysterectomy, bilateral salpingo-oophorectomy, para-aortic lymph node dissection(b2), omental subtotal hysterectomy, and lower anterior rectal resection after receiving a combination of PTX plus CBDCA chemotherapy. Macroscopically, complete resection was achieved and histopathological examination of the resectedspecimen showedpoorly differentiatedserous adenocarcinoma. After surgery, additional chemotherapy was administered. However, increasing only lesser curvature of stomach lymph node, we performed laparoscopic lymph node resection as debulking surgery. It is often said that macroscopic complete resection of ovarian cancer improves the prognosis. In particular, we hope that this patient will survive longer with a sustainable quality of life as a result of laparoscopic stomach- andnerve -sparing surgery.

Abstract
Myxofibrosarcoma(MFS)is one of the most common sarcomas in the extremities of elderly patients.We report a rare case of MFS originating in the retroperitoneum.A 65-year-old man presented to our hospital with an intraabdominal tumor, which was identified by abdominal CT during an investigation of an abdominal protuberance.Contrast -enhanced CT and MRI revealed a 18×12 cm mass in the left retroperitoneum.The patient underwent retroperitoneum tumor resection.Operative findings showed that there was an indistinct area between the left side of the tumor and the abdominal wall.There was no residual tumor macroscopically after the operation.The histopathological diagnosis was MFS arising from the retroperitoneum. Four months later, local recurrence and para-aortic lymph node metastasis were diagnosed.We performed tumor resection; however, the recurrent tumor had invaded the iliopsoas and iliac muscles.Additionally, there was peritoneal dissemination around the tumor.Five months after the initial surgery, a recurrence on the back was identified.He died 7 months after the first operation.According to previous reports, patients who undergo an operation with pathologically negative margins achieve better surgical outcomes.Therefore, it is important to perform expanded resection with enough surgical margin as possible.

Abstract
We report 2 cases of systemic steroid therapy for hyperbilirubinemia after right hepatic lobectomy for liver metastases from colorectal cancer.One of the patients was a 65-year-old man, diagnosed with transverse colon cancer with multiple liver metastases.After surgery for the primary lesion and chemotherapy(FOLFOX plus bevacizumab, FOLFIRI plus panitumumab), he underwent right hepatic lobectomy for the liver metastasis.His preoperative ICG 15 min was 8%.Conjugated hyperbilirubinemia without biliary stenosis occurred after the hepatectomy.Two courses of pulse steroid therapy were effective for only a limited period.After initiation of oral prednisolone therapy, his hyperbilirubinemia decreased.The other patient was a 66- year-old man with rectal cancer who underwent a low anterior resection.Postoperatively, a liver metastasis appeared.After CapeOX therapy, he underwent right hepatic lobectomy.His preoperative ICG 15 min was 5%.Conjugated hyperbilirubinemia occurred after hepatectomy.Pulse steroid therapy was effective for only a limited period.After initiation of prednisolone therapy, his hyperbilirubinemia decreased.In both cases, fatty changes in the liver were detected.Chemotherapy -associated hepatotoxicity may induce hyperbilirubinemia after hepatectomy.The effectiveness of systemic steroid therapy for hyperbilirubinemia is demonstrated by these cases.

Abstract
The patient was a 66-year-old woman, who was diagnosed with cT3N3M0, cStage III esophageal cancer with widespread lymph node metastases in the mediastinum and abdomen. She was treated with 2 courses of chemotherapy with docetaxel/ cisplatin/5-FU(DCF therapy). CT and FDG PET-CT showed a significant reduction in both the primary tumor and the metastatic lymph nodes following treatment. We performed subtotal esophagectomy and gastric tube reconstruction with lymphadenectomy. The histopathological findings showed no residual viable tumor cells or foreign body-type giant cells with necrosis. The pathological effect of chemotherapy was defined as Grade 3(pCR). Our case suggested that DCF chemotherapy is potentially a very effective treatment for advanced esophageal cancer with widespread lymph node metastases.

Abstract
Esophageal adenoid cystic carcinoma (EACC) is a very rare form of malignant tumor in the esophagus. Here, we report the case of a 78-year-old man who was diagnosed with EACC by preoperative endoscopic biopsy. Thoracoscopy-assisted subtotal esophagectomy with lymph node dissection was carried out. Microscopic examination of the resected specimen suggested that the tumor invaded to submucosal layer and showed no lymph node metastasis. Histologically, tumor primarily exhibited an alveolar solid pattern with partial cribriform and tubular patterns. Alcian blue staining showed many mucoid materials within the glandular cavity formed by tumor cells. Immunohistochemical studies revealed that the tumor cells reacted with pan-cytokeratin immunostains and expressed vimentin and S-100 protein. Collectively, the tumor was diagnosed as primary EACC, T1bN0M0 according to “Japanese Classification of Esophageal Cancer 10th edition.” The patient showed no recurrence sign 12 months after the surgery. The current study also reviewed 35 EACC cases reported in Japanese literatures from 1990 to 2014. Combined with our case, we found that EACC is less frequently accompanied by lymph node metastasis as compared to esophageal squamous cell carcinoma, especially at the early stage. The prognosis of EACC is relatively better when tumors have no lymph node metastasis.

Abstract
The aim of this study was to compare the efficacy of self-expandable metallic stent (SEMS) and transanal tube as preoperative treatments for left-sided obstructive colon cancer. Forty-three patients (the SEMS group: 28 cases, the tube group: 15 cases) were included in this study. Clinicopathological data (age, sex, tumor location, depth, histological type, stage) were comparable between the 2 groups. In addition, there was no difference in intestinal decompression rate between the SEMS group and the tube group (technical success rate: 100% vs 86.7%, clinical success rate: 92.8% vs 73.3%, complication rate: 7.1% vs 0%). A significantly higher number of patients in the SEMS group underwent laparoscopic surgery because of difference of historical background. However, no significant difference was observed between the 2 groups in postoperative outcome(complication rate, hospital stay duration). SEMS insertion had several benefits compared to transanal tube placement, such as the resumption of oral intake because of rapid resolution of obstruction and easier management because SEMSs do not require washing. SEMS insertion could be a safe and effective bridge to subsequent surgery in patients with left-sided obstructive colon cancer.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) has the poorest prognosis of all malignancies and is largely resistant to standard therapy. Novel treatments against PDAC are desperately needed. Anti-Gal is the most abundant natural antibody in humans, comprising about 1% of immunoglobulins and is also naturally produced in apes and Old World monkeys. The anti-Gal ligand is a carbohydrate antigen called “α-gal epitopes” with the structure Galα1-3Galβ1-4GlcNAc-R. These epitopes are expressed as major carbohydrate antigens in non-primate mammals, prosimians, and New World monkeys. Anti-Gal is exploited in cancer vaccines to increase the immunogenicity of antigen-presenting cells (APCs). Cancer cells or PDAC tumor lysates are processed to express α-gal epitopes. Vaccination with these components results in in vivo opsonization by anti-Gal IgG in PDAC patients. The Fc portion of the vaccine-bound anti-Gal interacts with Fcγ receptors of APCs, inducing uptake of the vaccine components, transport of the vaccine tumor membranes to draining lymph nodes, and processing and presentation of tumor-associated antigens (TAAs). Cancer vaccines expressing α-gal epitopes elicit strong antibody production against multiple TAAs contained in PDAC cells and induce activation of multiple tumor-specific T cells. Here, we review new areas of clinical importance related to the α-gal epitope/anti-Gal antibody reaction and the advantages in immunotherapy against PDAC.

Abstract
We report a case of radical resection of rectal cancer with multiple liver and lung metastases after preoperative chemotherapy. A 54-year-old woman presented with abdominal pain and loss of body weight due to rectal cancer with multiple liver and lung metastases. Therefore, the patient received 14 courses of bevacizumab+mFOLFOX6, and 7 courses of panitumumab+FOLFIRI. After the chemotherapy, the size of the distant metastases reduced by 62% on computed tomography, according to RECIST. Due to the reduction in size, a conversion surgery was attempted. First, an abdominal operation with laparoscopy was performed, and 2 months later an operation to resect the lung metastases via thoracoscopy was performed. Currently, 3 months after surgery, the patient is alive, without recurrence.

Abstract
A 70-year-old woman who complained of abdominal pain and a prolapsed tumor from the anus was diagnosed with an intestinal obstruction resulting from anal canal cancer. Computed tomography (CT) and magnetic resonance imaging revealed a huge tumor (11×5×12 cm) invading the vagina and levator ani muscle. Enlarged inguinal lymph nodes on both sides indicated metastasis. The clinical stage was T4b (vagina, levator ani muscle, and pudenda) N0H0M1a (LYM), stage IV (Japanese Classification of Colorectal Carcinoma: 8th edition). As curative resection was not possible, a transvers colostomy was performed to relieve the intestinal obstruction. This was followed by chemoradiotherapy (45 Gy/1.8 Gy×25; TS-1, 80 mg/body for 2 weeks and a 1-week interval, for 2 courses) and up to 10 courses of Bev+mFOLFOX6 continuously. After this regimen, there was a remarkable reduction in tumor size. Positron emission tomography-CT revealed no FDG uptake in the primary rectal site or inguinal lymph nodes, but a maximum standardized uptake value (SUVmax) of 6.3 was detected in the vagina. Six weeks after chemotherapy, the patient underwent a pelvic exenteration including resection of the vagina, bladder, and pudenda. The pathological stage was yp T4b (vagina) N0H0M0, stageⅡ. Curative resection was performed, and the patient had a Grade 2 pathological response after chemoradiotherapy.

Abstract
A 77-year-old-woman, whose chief complaint was anemia, was referred to our hospital and diagnosed with advanced gastric cancer with liver metastasis and lymph node metastasis.Gastrointestinal endoscopy showed a tumor on the lesser curvature of the gastric corpus.Histologically, biopsy specimens indicated adenocarcinoma with genetic amplification of human epidermal growth factor receptor type 2.Computed tomography and magnetic resonance imaging showed lymph node metastasis and liver metastasis.The patient received a total gastrectomy and a partial liver resection after combination chemotherapy consisting of capecitabine, cisplatin, and trastuzumab.Histopathological examination of a resected specimen showed a minute residual cancer nest at the subserosa of the stomach and lymph node metastasis, but no liver metastasis. This combined modality therapy can be considered an effective treatment for gastric cancer with liver metastasis, and we hope that it will be established as a standard therapy.

Abstract
BACKGROUND Although laparoscopic hepato-biliary-pancreatic surgery has been widely adopted, use of laparoscopic resection for hepatocellular carcinoma (HCC) with advanced portal vein tumor thrombus (PVTT) is uncommon because of the complications involved. METHODS From June 2010 through November 2013, 200 laparoscopic hepatectomies were performed. We report the short-term outcome of laparoscopic hepatectomy for HCC with advanced PVTT in 3 patients. Video presentation is a demonstration of the operative procedures employed in Case 3. In this case, the left hepatic artery and left hepatic duct were divided before tumor thrombectomy, and the bifurcation of the portal vein was clearly visible. RESULTS Three female patients with HCC concomitant with PVTT in the portal trunk or the opposite branch underwent laparoscopic left hepatectomy with tumor thrombectomy using a laparoscopy-assisted technique (1 patient) or pure laparoscopic technique (2 patients). The median operative time was 592 min (range, 555-891 min), and median estimated blood loss was 1182 ml (range, minimal amount-4800 ml). The median length of hospital stay was 19 days (range, 9-22 days), and there was no postoperative mortality. In Case 1, recurrent tumors developed in the residual lobe after curative resection, and the patient died 10 months after the surgery despite treatment with sorafenib and transcatheter arterial chemoembolization. In Case 2, the patient survived for 10 months after curative resection without tumor recurrence. In Case 3, the patient was treated with sorafenib 1 month after palliative resection; she survived for 4 postoperative months, during which decreased tumor marker levels were observed. CONCLUSIONS Laparoscopic hepatectomy for HCC with advanced PVTT is a safe and feasible procedure in selected patients, when performed by surgeons with expertise in hepatic surgery and minimally invasive techniques. Although these patients cannot be cured by surgery alone, early adjuvant therapy followed by laparoscopic surgery might contribute to a good outcome.

Abstract
A questionnaire survey on postoperative adjuvant chemotherapy for gastric cancer was conducted for 76 hospitals affiliated with the Hiroshima Oncology Group of Gastric Cancer in Hiroshima prefecture in January 2011. Responses were obtained from 29 hospitals, including 12 core cancer treatment hospitals, and the following results were obtained. The percentage of patients completing 1 year of oral S-1 was >70%, affecting approximately 75% of the entire hospital cohort. Dose reduction was conducted in approximately 30% of patients because of age, poor PS, and renal insufficiency. The standard S-1 regimen (4 weeks of S-1 treatment followed by 2 weeks of rest)was adopted in almost half of the patients, whereas the rest of the patients received another treatment schedule such as 2 weeks of treatment followed by 1 week of rest. Dose reduction and withdrawal of S-1 due to adverse events were conducted more frequently in hospitals with low completion rates of 1-year S- 1 treatment than those with a high completion rate. S-1 was most commonly discontinued because of subjective adverse events and patient request, although the discontinuation rate according to objective adverse events such as bone marrow depression was not very high. The fact that some hospitals had high completion rates suggested the importance of supplementary tools for patient IC.

Abstract
BACKGROUND There is controversy regarding strategies for treating very elderly patients with gastric carcinoma. We aimed to assess survival after surgery in very elderly patients according to their clinical characteristics. METHODS Gastric cancer patients aged ≥85 years were retrospectively reviewed. There were no significant differences in clinical characteristics between 58 patients with curative resection (OP group) and 32 patients with best supportive care alone (BSC group) in cancer stage IA-IIIC and with a performance status of 0-3. RESULTS Overall survival (OS) was significantly better in the OP group than in the BSC group in females [hazard ratio (HR) 0.27, 95 % confidence interval (CI) 0.12-0.57, P < 0.001] but not in males (HR 0.71, 95 % CI 0.35-1.49, P = 0.35). OS was significantly better in the OP group in patients aged 85-89 years (HR 0.44, 95 % CI 0.25-0.78, P = 0.006) but not in patients aged ≥90 years (HR 0.47, 95 % CI 0.12-1.66, P = 0.24). OS was significantly better in the OP group in patients with stage IB-IIIC cancer (HR 0.29, 95 % CI 0.14-0.58, P < 0.001) but not in patients with stage IA cancer (HR 0.52, 95 % CI 0.21-1.27, P = 0.15). CONCLUSIONS Females, patients aged 85-89 years, and patients with stage IB-IIIC cancer had significantly better OS with surgery than without. For males, patients aged ≥90 years, or stage IA patients, the decision to perform surgery should be carefully made, and BSC might be an optimal strategy.

Abstract
A 58-year-old man was admitted to the author's institution with complaints of dysphagia and tarry stool. An advanced squamous cell carcinoma of the esophagogastric junction was revealed by endoscopy. The clinical stage was GE, T4, N1, H0, M0, cStageIVa, according to the Japanese Classification of Esophageal Cancer. Low-dose FP chemotherapy(continuous 5-FU div of 500mg/day with intermittent CDDP div of 10mg/day)was used. The tumor size was remarkably reduced while the side effects were trivial. A clinically complete response was recognized with CT and with pathological findings from endoscopic biopsy. As a recurrence was diagnosed in the off-treatment period, the same regimen was resumed. Soon, a complete response was again. The patient is doing well with no reoccurrence after almost 10 years, with a low-dose FP chemotherapy.

Abstract
AIM The Hiroshima Oncology Group of Gastric Cancer(HOG-GC)distributed a multiple-answer questionnaire to investigate the realities of chemotherapy for gastric cancer. SUBJECTS AND METHOD Seventy-six hospitals in Hiroshima were surveyed. The Japanese classification was used for the staging criteria. RESULTS Forty-one hospitals, including 10 centers for cancer treatment, completed and returned the questionnaires. For stage II & III cases requiring adjuvant chemotherapy, S-1 was the most commonly used(84%)regimen. A standard starting dose was used in 79% of these cases, and S-1 was administered for one year continuously in 84% of the cases. For stage I B & II (T1), S-1 and UFT were used in 45%and 20%of the cases, respectively. In cases with non-resectable gastric cancer, S-1 plus CDDP and S-1 alone were used as a first-line therapy in 62% and 26% of the patients under 75 years age, respectively, and in 33% and 46% of the patients older than 75 years of age, respectively. In patients with ascites and peritoneal dissemination, S-1 plus CDDP, S-1, S-1 plus DTX, S-1 plus PTX, and PTX were used in 26%, 15%, 21%, 17%, and 17% of cases, respectively. Some of the patients with peritoneal dissemination underwent gastrectomy. CONCLUSION S-1 was widely used for gastric cancer chemotherapy in Hiroshima Prefecture. Taxane-containing regimens or palliative gastrectomy were commonly used in cases with peritoneal dissemination.

A new predictive indicator for development of pressure ulcers in bedridden patients based on common laboratory tests results. J Clin Pathol 2008; 61:514-8.

Abstract
Background:Various scales have been devised to predict development of pressure ulcers on the basis of clinical and laboratory data, such as the Braden Scale (Braden score), which is used to monitor activity and skin conditions of bedridden patients. However, none of these scales facilitates clinically reliable prediction.Aims:To develop a clinical laboratory data-based predictive equation for the development of pressure ulcers.Methods:Subjects were 149 hospitalised patients with respiratory disorders who were monitored for the development of pressure ulcers over a 3-month period. The proportional hazards model (Cox regression) was used to analyse the results of 12 basic laboratory tests on the day of hospitalisation in comparison with Braden score.Results:Pressure ulcers developed in 38 patients within the study period. A Cox regression model consisting solely of Braden scale items showed that none of these items contributed to significantly predicting pressure ulcers. Rather, a combination of haemoglobin (Hb), C-reactive protein (CRP), albumin (Alb), age, and gender produced the best model for prediction. Using the set of explanatory variables, we created a new indicator based on a multiple logistic regression equation. The new indicator showed high sensitivity (0.73) and specificity (0.70), and its diagnostic power was higher than that of Alb, Hb, CRP, or the Braden score alone.Conclusions:The new indicator may become a more useful clinical tool for predicting presser ulcers than Braden score. The new indicator warrants verification studies to facilitate its clinical implementation in the future.
