Abstract
BACKGROUND APC and MUTYH are both well-known colorectal polyposis causative genes. However, 30-50% of colorectal adenomatous polyposis cases are classified as colonic adenomatous polyposis of unknown etiology and lack identifiable pathogenic variants. Although guidelines recommend total proctocolectomy for colonic adenomatous polyposis of unknown etiology with over 100 adenomas, evidence is lacking. This study presents a unique case of localized colonic adenomatous polyposis of unknown etiology with multiple adenocarcinomas, treated with hemicolectomy and regional lymph node dissection. CASE PRESENTATION The patient was a 72-year-old woman whose colonoscopy revealed numerous polyps and two adenocarcinomas localized in the right side of the colon, with no lesions in the left side. The patient had no family history of polyposis or colorectal cancer. No extracolonic lesions, enlarged lymph nodes, or distant metastases were found. Considering the patient's age and lesion localization, laparoscopic right hemicolectomy with regional lymph node dissection was performed. Histopathological diagnosis revealed three adenocarcinoma lesions with no lymph node metastasis. The most advanced pathological stage was T2N0M0 Stage I (UICC 8th edition). The patient was alive 5 years postoperatively, without recurrence of cancer or polyposis in the remaining colon and rectum. To diagnose hereditary colorectal cancer/polyposis, a germline multigene panel testing for APC, EPCAM, MBD4, MLH1, MLH3, MSH2, MSH3, MSH6, MUTYH, NTHL1, PMS2, POLD1, POLE, and TP53 was performed using DNA extracted from blood samples: however, no pathogenic variant was detected. Therefore, the patient was diagnosed with colonic adenomatous polyposis of unknown etiology. CONCLUSIONS In this rare case, colonic adenomatous polyposis of unknown etiology, with numerous adenomatous polyps and multiple adenocarcinomas localized in the right side of the colon, was successfully treated with right hemicolectomy and regional lymph node dissection. Despite genetic analysis, no causative germline variants were identified. Segmental colectomy according to the distribution of polyps might be a curative approach.

Abstract
CD8+ T cells affect the outcomes of pancreatic ductal adenocarcinoma (PDAC). Using tissue samples at pre-treatment to monitor the immune response is challenging, while blood samples are beneficial in overcoming this limitation. In this study, we measured peripheral antigen-specific CD8+ T cell responses against four different tumor-associated antigens (TAAs) in PDAC using flow cytometry and investigated their relationships with clinical features. We analyzed the optimal timing within the treatment course for effective immune checkpoint inhibition in vitro. We demonstrated that the frequency of TAA-specific IFNγ+4-1BB+ CD8+ T cells was correlated with a fold reduction in CA19-9 before and after neoadjuvant therapy. Moreover, patients with TAA-specific IFNγ+4-1BB+ CD8+ T cells after surgery exhibited a significantly improved disease-free survival. Anti-PD-1 treatment in vitro increased the frequency of TAA-specific IFNγ+4-1BB+ CD8+ T cells before neoadjuvant therapy in patients, suggesting the importance of the timing of anti-PD-1 inhibition during the treatment regimen. Our results indicate that peripheral immunophenotyping, combined with highly sensitive identification of TAA-specific responses in vitro as well as detailed CD8+ T cell subset profiling via ex vivo analysis, may serve as peripheral biomarkers to predict treatment outcomes and therapeutic efficacy of immunotherapy plus neoadjuvant chemotherapy.

Abstract
PURPOSE To investigate the association between perioperative deglutition screening and postoperative respiratory complications (PRCs) in elderly patients undergoing gastrectomy for gastric cancer. METHODS We analyzed data from 86 patients with gastric cancer (aged ≥ 70 years) who underwent gastrectomy between October, 2016 and November, 2018. Videofluoroscopic swallowing examinations (VFSEs) were performed before and after surgery. We examined the association of these results with postoperative respiratory complications, as well as the relationships between demographic, operative, and swallowing function assessment data. RESULTS PRCs were identified in 16 patients. The results of pre- and postoperative VFSE showed abnormalities in 28 and 32 patients, respectively. Multivariate analysis revealed that abnormalities in the postoperative VFSEs were strongly associated with the development of PRCs (P = 0.002). The findings of this analysis suggests that ventilatory impairment, a Charlson comorbidity index score ≥ 3, and an open surgical approach are independent risk factors for PRCs. CONCLUSION This is the first study to demonstrate the efficacy of perioperative assessment of swallowing function using VFSE for predicting PRCs in elderly patients undergoing gastrectomy for gastric cancer.

Abstract
BACKGROUND Cardiac tamponade is a rare postoperative complication of esophageal cancer surgery, which leads to rapid hemodynamic changes and can be fatal if not treated properly and promptly. Herein, we report a case of cardiac tamponade after thoracoscopic subtotal esophagectomy and retrosternal gastric tube reconstitution for esophageal cancer that was successfully treated with surgical drainage. CASE PRESENTATION An 86-year-old man with lower thoracic esophageal cancer underwent thoracoscopic subtotal esophagectomy and retrosternal gastric tube reconstitution. No intra-operative complications were observed. On the first postoperative day, tachycardia and hypotension were observed, and pericardial effusion was identified on computed tomography images. The patient was diagnosed with obstructive shock secondary to cardiac tamponade. As percutaneous puncture drainage was not possible due to the presence of a retrosternal gastric tube, pericardiotomy with a small left anterior thoracotomy was performed, and a large amount of hematogenous fluid was drained, which instantly improved circulation. On the second postoperative day, the patient showed decreased pulse pressure, and computed tomography revealed a residual and enlarged hematoma around the right ventricle. The patient underwent surgical drainage and another pericardiotomy with a small right anterior thoracotomy was performed to drain the hematoma. At this time, multiple injuries to the fatty tissue, epicardium, and myocardium with active bleeding were observed on the anterior surface of the right ventricle near the root of the pulmonary artery. In this patient, the ascending aorta ran further to the right and dorsal sides than usual, causing the anterior wall of the right ventricle near the root of the pulmonary artery to be closer to the back of the sternum. This abnormality may have contributed to injury during the creation of the retrosternal pathway, leading to cardiac tamponade. CONCLUSIONS Cardiac tamponade after esophagectomy can occur because of manipulation during creation of the retrosternal route, with an anomaly in the aortic position being present in this case. Gentle manipulation and selection of the reconstruction route according to the patient's condition are necessary in cases with such anatomical abnormalities.

Abstract
AIM Neoadjuvant transcatheter arterial chemoembolization (TACE) for large tumors is controversial, especially in the minimally invasive surgery era. The aim of this study was to compare features between groups treated with neoadjuvant TACE followed by surgery (TACE + surgery) or upfront surgery for hepatocellular carcinoma >5 cm. METHODS In this exploratory, multicenter, randomized phase I study, the primary measure was 2-year disease-free survival (DFS). Secondary measures were resection rate, necrosis rate by TACE, 2-year overall survival, and site of recurrence. A total of 30 patients were randomly allocated to each arm. RESULTS The two arms did not differ in patient characteristics. The median time to surgery from randomization was 48 days for TACE + surgery and 29 for surgery only (p < 0.001). Postoperative morbidities did not differ between arms. The 2-year DFS, overall survival, and resection rates were 56.7%, 80.0%, and 93.3%, respectively, in the TACE + surgery arm, and 56.1%, 89.9%, and 90.0% in the upfront surgery arm. Minimally invasive surgery was carried out in 35.7% in the TACE + surgery arm and in 29.6% in the upfront surgery arm. The median necrosis rate by TACE was 90.0%. In resected specimens, invasion to the hepatic vein was less with TACE + surgery (3.6% vs. 22.2%, p = 0.0380). In cases of 100% necrosis with TACE, 2-year DFS was 100%. Site of recurrence did not differ between groups. CONCLUSION Neoadjuvant TACE did not improve 2-year DFS, and neoadjuvant TACE allowed delay of surgical treatment without increased morbidity and cancer progress.

Abstract
AIM To investigate the current treatment for liver metastasis and clarify the indications for percutaneous thermal ablation for liver metastasis. METHODS Ninety-two patients were enrolled and retrospectively analyzed. The patients underwent hepatectomy and/or percutaneous thermal ablation for liver metastases between January 2012 and December 2018. Twenty-six patients who underwent ablation treatment and seven patients who underwent both ablation and hepatectomy were included in the ablation treatment group (group A). We compared these patients with 59 patients who underwent hepatectomy only (group H). Subgroup analyses were performed between ablation (group AC) for colorectal liver metastasis and hepatectomy (group HC) for colorectal liver metastasis in 17 and 53 patients, respectively. RESULTS The percentage of liver metastases other than colorectal cancer in group A was higher than that in the group H. Maximum tumor size in group A was significantly smaller than that in group H. Similarly, the patients in group AC were significantly older and demonstrated higher total bilirubin, lower serum albumin, and lower platelet counts than those in group HC. Overall survival was poorer in the AC group than that in the HC group. However, no differences were observed at metastasis ≤2 cm in size. CONCLUSIONS Percutaneous thermal ablation was performed for many cancer types than hepatectomy. It is performed in elderly patients. We suggested that ablation for colorectal liver metastasis sized ≤2 cm is a suitable indication.

Abstract
The patient is a 70s woman. She underwent cystectomy for bladder cancer 6 years ago and had a ureterocutaneous fistula in the right lower abdomen. After colonoscopy for positive fecal occult blood, a type 1 elevated lesion was found in the ascending colon, which was diagnosed as a well-differentiated adenocarcinoma on biopsy. Surgery was performed with a single hole. The approach from the right lower abdomen, where the ureterocutaneous fistula and ureter are located, was avoided, and the approach from the hepatic flexure of the transverse colon was used first. After the right colon was mobilized, the large mesh adhesions around the ureter were carefully dissected, and the right ureter was identified and preserved, extending from the lateral ascending colon to the abdominal wall. The ileal artery was dissected at the root and after dissection of the D3 lymph node, the intestine was dissected and anastomosed extracorporeally. The operative time was 246 minutes with small amount of blood loss. The patient was discharged on the 6th postoperative day without any postoperative complications. The pathology result was pT3N0M0, pStage Ⅱa, and radical resection had been performed. The patient is currently undergoing recurrence-free follow-up.

Abstract
A female in her 70s underwent right hepatectomy with resection of caudate lobe and extrahepatic bile duct for perihilar cholangiocarcinoma(T2aN0M0, Stage Ⅱ: Biliary Cancer Treatment Regulations, 7th edition). On the 4th postoperative day, the patient had impaired consciousness, which worsened to almost coma on the 5th postoperative day. On the same day, a blood test showed high ammonia level, thus the state was thought to be hepatic encephalopathy. Contrast -enhanced CT on the same day showed thrombus from the main trunk of the portal vein to the remnant left branch, narrowing of the lumen of the vessel. Simultaneously, enlarged portosystemic shunt in the pelvic floor due to portal hypertension induced by the thrombosis. Plasmapheresis was performed, and anticoagulation with sodium heparin and antithrombin Ⅲ were started. Then, the portal vein thrombus was reduced, and encephalopathy was improved. She was discharged from the hospital on postoperative day 48. She was treated with edoxaban as an outpatient, and anticoagulation therapy was terminated after a CT scan 6 months after surgery, which confirmed no recurrence of thrombus. She is now alive without recurrence of thrombus or tumor for about 2 years after the surgery.

Abstract
We report a case of locally advanced rectal cancer that could not be curatively resected, in which the patient underwent conversion surgery after chemotherapy. The patient is a 70-year-old woman. She came to our hospital with a chief complaint of lower abdominal pain, and a close examination revealed rectal cancer with invasion of the external iliac artery and pelvic wall. She was treated with mFOLFOX6 plus cetuximab for locally advanced rectal cancer that was not amenable to surgical resection. After 11 courses of chemotherapy, significant shrinkage of the tumor was observed, and robot assisted laparoscopic high-anterior resection was performed. The patient didn't relapse at 12 months after surgery without adjuvant chemotherapy.

Abstract
74-year-old woman was diagnosed with locally advanced unresectable transverse colon cancer. She started CAPOX therapy as first-line therapy after ileostomy. After second course, MSI-high was detected, so nivolumab plus ipilimumab combination therapy was started as second-line therapy. After 4 courses of combination therapy, she was judged to be in partial response and surgery was performed. Histopathological diagnosis of the surgical specimen showed complete response, and she is still alive without recurrence 15 months after surgery.

Abstract
A 80s man was diagnosed circulated type 2 colon cancer at the transverse colon, and pathological findings was adenocarcinoma( por1). Genomic findings were microsatellite instability-high(MSI-H), all RAS wild type and BRAFV600E mutated. Contrast-enhanced CT showed an enlarged lymph nodes(#221, #222, #223, #214)along the middle colic and superior mesenteric artery. Clinical diagnosis was a locally advanced unresectable transverse colon cancer, cT4aN3M1a(LYM), cStage Ⅳa. Drug therapy with pembrolizumab was prescribed. Six months later, contrast-enhanced CT and PET demonstrated remarkable shrinkage of the primary tumor and lymph nodes except 2 peri-colic enlarged lymph nodes. Primary lesion turned almost undetectable, however the biopsy demonstrated residual tumor. Two months later, CT showed that the residual lymph nodes had also disappeared.

Abstract
BACKGROUND The Adjuvant S-1 for Cholangiocarcinoma Trial (JCOG1202, [ASCOT]) was a multicenter, randomized controlled trial aimed at investigating the efficacy and safety of adjuvant chemotherapy (AC) with S-1 for resected biliary tract cancer (BTC). This trial reported that overall survival was prolonged with AC compared with observation. METHODS With the aim of increasing enrollment, the present survey biannually recorded the number of patients eligible for enrollment into ASCOT and reasons for ineligibility among patients who had undergone surgery for BTC from April 2015 to September 2017 at 36 institutions participating in ASCOT. RESULTS Of 2039 patients who underwent surgery for BTC, 211 (10.3%) were already enrolled, 166 (8.1%) were eligible but had not been enrolled, and 1662 (81.5%) were ineligible. Among ineligible patients, the predominant reasons for ineligibility were patient refusal (n = 332, 20.0%), pathologic stage (pT1N0; n = 248, 14.9%), age (≥ 81 years; n = 196, 11.8%), and prolonged postoperative complications (n = 176, 10.6%). CONCLUSIONS Patients undergoing surgery for BTC are a heterogeneous cohort comprising patients with earlier pathologic stage, advanced age, and prolonged postoperative complications. These factors should be considered during the design of future clinical trials of perioperative treatments for resectable BTC.

Abstract
The patient is a 50s year old man. He visited his local doctor with complaints of anal pain and bloody stools, and a rectal examination revealed a tumor on the anterior wall of the rectal canal. CT imaging showed tumors invading the prostate, urethra, and anorectal muscles, and a 3 mm-sized nodule was found in the lungs. The patient was diagnosed as cT4bN1M1a, Stage Ⅳ, and total neoadjuvant chemotherapy was planned as preoperative treatment. The 5 Gy×5 times radiation therapy followed by 5 courses of CAPOX plus BEV as preoperative chemotherapy and CAPOX. CAPOX was administered. After completion of treatment, the colonoscopy showed PR, and MRI showed clear boundary between the prostate and tumor but invasion into the anorectal muscles; CT showed no lung metastasis, and preoperative diagnosis was ycT4bN0M0, ycStage Ⅱ. Robotic-assisted rectal amputation and left lateral lymph node dissection were performed under general anesthesia. Pathologically, the patient was diagnosed as ycT4bN0M0, Stage Ⅱ, and the efficacy was determined as TRG 1(AJCC). Vertical dissection was negative and radical resection was possible.

Abstract
In aging society, the number of colorectal cancer patients who take antithrombotic drugs is increasing. However, there are not established guidelines for perioperative management for antithrombotic drugs in laparoscopic surgery. Here, we investigated the clinical outcomes of antithrombotic drugs withdrawal and perioperative heparinization in laparoscopic surgery for colorectal cancer patients taking antithrombotic drugs. From January 2015 to December 2017 in our center, patients who took antithrombotic drugs and underwent laparoscopic surgery for colorectal cancer were reviewed retrospectively. The association between postoperative complications and heparinizations was analyzed. Among 79 patients taking antithrombotic drugs, heparinization was performed in 40 patients(50.6%). The total length of hospital stay in heparinization group was 21 days and significantly longer than 13 days in the non-heparinization group. There were no significant differences in the operation time, intraoperative blood loss, and postoperative complications between the 2 groups. The antithrombotic drugs withdrawal and perioperative heparinization were suggested to be safe and feasible in laparoscopic surgery for patients with colorectal cancer.

Abstract
A male in his twentieth was referred to our hospital for jaundice. Computed tomography(CT)showed dilation of the intrahepatic and extrahepatic bile ducts and showed a lesion at the ampulla of Vater, which caused obstructive jaundice. Upper gastrointestinal endoscopy revealed a tumor of protruded-predominant type with raised margins at the ampulla of Vater, and biopsy from the lesion indicated malignancy. With no apparent distant metastasis, radical resection was assumed to be possible, thus we performed subtotal stomach preserved pancreatoduodenectomy. Before the operation, endoscopic retrograde biliary drainage(ERBD)was unsuccessful because of the existence of the tumor, so percutaneous transhepatic cholangio drainage(PTCD)was conducted. After the operation, although pancreatic fistula(ISGPF Grade B)occurred, it improved with conservative treatment, and he discharged at 30 postoperative days. Histopathological examination revealed signet-ring cell carcinoma among the tumor at the ampulla of Vater, which was infiltrating into the pancreas. Final diagnosis was pT3, pN0, M0, pStage ⅡA. Now he is alive without recurrence for 3 and a half years.

Abstract
A woman in her 50s underwent sigmoid colectomy and D3 lymph node dissection for sigmoid cancer(pT3, N0, M0, Stage Ⅱ: Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma 9th). She received adjuvant chemotherapy with capecitabine. Seven months after surgery, contrast-enhanced computed tomography( CECT) scan revealed a small mass in the segment 2 (S2) of the liver with dilation of peripheral intrahepatic bile duct, and the size of this mass and the bile duct dilatation were gradually increased. FDG positron emission tomography(FDG-PET)/CT showed abnormal FDG uptakes in the lesion of S2, and EOB-MRI detected other small lesions in the S6 and S7. Considering the results of image examinations, multiple lesions intrahepatic cholangiocarcinoma was firstly assumed. However, immunohistochemistry of the tumor obtained by endoscopic retrograde cholangiopancreatography (ERCP) showed cytokeratin 7-negative. Based on preoperative diagnosis of liver metastasis from colon cancer rather than intrahepatic cholangiocarcinoma, we performed left lobectomy, partial hepatectomy of S6 and S7 and cholecystectomy. In the resected specimen, the tumor was macroscopically located in the intrahepatic bile ducts. Microscopically, there existed atypical epithelial cells with glandular duct-like structure, and the lesions was histopathologically diagnosed as metastasis from colon cancer. She was discharged on the 10th postoperative day, and she is alive without recurrence one year after surgery.

Abstract
Successful resection of intra-abdominal tumors using indocyanine green (ICG) fluorescence imaging has not been reported. Here, we report a rare case of an intra-abdominal desmoid-type fibromatosis successfully resected using this technique after intersphincteric resection (ISR) for rectal cancer. One year after ISR for rectal cancer in a 47-year-old man, computed tomography showed a 50-mm intra-abdominal tumor near the left common iliac vein. Surgical resection was performed. The tumor was located in the mesentery of the remnant rectum after ISR. ICG fluorescence imaging confirmed the blood supply to the mesentery of the distal remnant rectum after tumor excision. The anal canal was successfully preserved without creating a permanent colostomy. The tumor was safely resected with resection margins, diagnosed as desmoid-type fibromatosis. No tumor recurrence was observed 6 months post-resection. This was the first case report to demonstrate the utility of this technique for an intra-abdominal tumor resection.

Abstract
A man in his 50s underwent laparoscopic sigmoid colectomy for sigmoid colon cancer with liver metastasis(cT4aN1M1a, cStage Ⅳa), followed by partial liver resection(S4, S6). One and a half years after the initial surgery, CEA and CA19-9 increased, and contrast-enhanced CT and MRI showed a hypovascular lesion with dilation of the distal pancreatic duct in the pancreatic body. Adenocarcinoma was detected by brushing cytology of the lesion and pancreatic juice cytology by ERCP. From the results of various examinations, the lesion was diagnosed as pancreatic ductal adenocarcinoma. We performed distal pancreatectomy, and initially the histopathological diagnosis was pancreatic body cancer(pT3N1aM0, pStage ⅡB). In a follow-up CT after surgery, a suspected metastatic lymph node was pointed out in the mediastinum, but it was difficult to distinguish between metastasis from colorectal cancer and one from pancreatic cancer. Immunostaining of the tumor tissue and comparative study of the excised specimens of colon and pancreas was performed in order to assume the primary lesion of the lymph node. As a result, both tissues were CK7(-)/CK20(+), and the lesion at first considered to be primary pancreatic cancer was originally the pancreatic metastasis from colon cancer. Bone metastases were also found on FDG-PET/CT around the same time, and then systemic chemotherapy for colorectal cancer was introduced. Four and a half years have passed since the first surgery, and he is still alive and undergoing treatment.

Abstract
Patient undergoing R0 resection have the good survival advantage following surgery for recurrent rectal cancer. Robotic surgery for anastomotic local recurrence of rectal cancer has never been reported before. An 80-year-old woman who had undergone high anterior resection for rectal cancer 1 years previously got colonoscopy. It revealed a 10 mm sized, elevated lesion on the anastomotic site, and a biopsy revealed an adenocarcinoma(tub1). Computed tomography and positron emission tomography-computed tomography showed no signs of distant metastasis, and we decided to conduct radical surgery with robot-assisted laparoscope. Robot-assisted laparoscopic lower anterior resection with resection of left hypogastric nerve was carried out. Histological assessment showed that R0 resection was performed. The patient was discharged on postoperative day 8th without postoperative complication. She is alive without recurrence at 1 year after the last operation.

Abstract
A woman in her 30s visited our hospital complaining primarily of melena. Colonoscopy revealed the presence of a type 1 tumor in 2 cm from anal verge. Contrast-enhanced CT showed an unresectable massive liver metastasis in the left lobe of the liver and another metastasis in the right lobe. The patient received front-line chemotherapy with Leucovorin, fluorouracil, oxaliplatin, and irinotecan(FOLFOXIRI)plus bevacizumab(BEV). A year later, a marked reduction of liver metastases and primary lesions was confirmed by CT scan imaging. A multidisciplinary team recommended resection of the liver metastases followed by laparoscopic intersphincteric resection for primary lesions. However, after 1 year, a recurrence was diagnosed in the liver; hence, FOLFOXIRI plus BEV was reintroduced for volume reduction. The patient underwent a repeat hepatectomy since enough volume reduction was confirmed. One year later, she experienced a re-relapse of the metastasis in the liver. Currently, she is still undergoing chemotherapy following 7 years since the first visit. Long-term survival can be expected following surgical treatment during chemotherapy.

Abstract
BACKGROUND In Japan, the standard treatment for squamous cell anal cancer(SCAC)has not been established. Herein, we report a case of SCAC that completely responded to chemoradiotherapy(CRT). CASE A woman in her 80s presented with anal pain and bleeding. Computed tomography revealed bilateral inguinal adenopathy and a tumor in the anal canal. Histopathological examination of endoscopic biopsies showed adenocarcinoma. Thus, she was diagnosed with anal canal adenocarcinoma and lymph node metastases:cT3, cN1a(No. 292), cM0, cStage Ⅲc(Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma, 9th edition). Owing to her advanced age and refusal of a stoma, CRT(S-1, mitomycin C, and radiotherapy)was administered with the expectation that salvage surgery in the form of rectal amputation would eventually be necessary. The tumor noticeably shrank after CRT. The patient is alive to this date,14 months after the final round of CRT.

Abstract
The case was a 61-year-old woman. She was diagnosed with autosomal dominant polycystic kidney disease(ADPKD)at the age of 38 and started hemodialysis at the age of 42. She was diagnosed with rectal cancer(RS)at the age of 61. Laparoscopic high anterior resection and D3 lymphadenectomy were carried out. Although the intra-abdominal space was limited by the huge renal cysts, laparoscopic surgery can be safely performed by arranging the port closer to the midline, taking the patient's position sufficiently, and using some useful tips. Laparoscopic surgery for the patient with ADPKD was considered a useful approach.

Abstract
A man in his 60s underwent pancreaticoduodenectomy(PD)for ampullary cancer(pT3, N1, M0, pStage ⅡB). One year after the operation, lymph node recurrence was observed, and gemcitabine/cisplatin regimen was introduced. Once the disease was controlled, but the tolerability of chemotherapy deteriorated due to severe anorexia and general fatigue around the 6th course of the regimen, thus we stopped the chemotherapy. The performance status was remarkably dropped and the oral intake was notably decreased, and subsequently he got hospitalized. Blood examination on admission showed signs of liver failure(Alb 1.9 g/dL, T-Bil 2.0 mg/dL, PT 36.2%, NH3 159μg/dL). CT scan revealed marked deterioration of fatty liver and newly recognized retention of ascites. We diagnosed this clinical state as liver dysfunction caused by aggravation of nonalcoholic fatty liver disease(NAFLD)due to pancreatic exocrine insufficiency after PD. Immediately pancreatic enzyme replacement therapy(pancrelipase)was performed, and liver function gradually improved. He was discharged 17 days after admission. One month after discharge, CT scan showed that the fatty liver was markedly improved and the ascites disappeared. Around the same time, the chemotherapy was able to be resumed with the improvement of general condition.

Abstract
BACKGROUND The risk factors for recurrence in patients with pStage Ⅱ colorectal cancer still remains controversial. The aim of this study was to investigate the risk factors for recurrence after surgery in patients with pStage Ⅱ colorectal cancer. METHOD We retrospectively reviewed 311 patients with primary pStage Ⅱ colorectal cancer who underwent radical resection without neoadjuvant therapy at our institute between January 2014 and December 2019. RESULTS Of 311 patients, 32 patients(10.3%)developed recurrences after surgery at a median follow-up of 32.9(0.23-74.2)months. The 3-year and 5-year recurrence-free survival(RFS)rate was 88.4% and 87.6%, respectively. A multivariate analysis for RFS showed that only pT4 (HR: 4.06, 95%CI: 1.60-10.29, p=0.003) was an independent risk factor. CONCLUSION This study revealed that pT4 was an independent risk factor for recurrence after surgery in patients with pStage Ⅱ colorectal cancer.

Abstract
We reported a case of rectal cancer with unresectable liver metastases treated with resection of the primary lesion followed by systemic chemotherapy with curative resection. A woman in her 40s was diagnosed with rectal RS carcinoma and unresectable liver metastasis, mFOLFOX6 plus panitumumab therapy was initiated after laparoscopic high anterior resection of the rectal lesion. After 5 courses of chemotherapy, significant shrinkage of the liver metastatic lesion and increase of the remnant liver volume were observed. Percutaneous transhepatic portal vein embolization( PTPE) was performed with the aim of further preserving remnant liver volume. Since the hepatic reserve was sufficient, the treatment strategy was to perform radical hepatectomy. Extended right hepatic lobectomy, S4 partial resection, and cholecystectomy were performed. The patient didn't relapse at 11 months after hepatectomy.

Abstract
A woman in her 60s realized heart palpitations and was pointed out anemia. CT revealed a tumor measuring 7 cm, with internal necrosis, originating from the gallbladder and invading the liver, and diagnosed as gallbladder cancer. There existed no distant metastasis and we performed cholecystectomy with partial resection of segment 4a+5 of the liver and lymph node resection. Histopathological examination revealed highly atypical cells with large nuclei and polynuclear cells and poor cell junctions in the specimen, and the tumor was histologically diagnosed as an undifferentiated carcinoma. Metastases were not detected in dissected lymph nodes, and this case was diagnosed as undifferentiated carcinoma of gallbladder, T3a, N0, M0, Stage ⅢA(JSHBPS 6th). She was discharged at 13 days after the operation with no apparent postoperative complications. Postoperative adjuvant chemotherapy with administration of TS-1 was conducted for half a year. Now over 5 years have passed since the operation, and she is alive without recurrence.

Abstract
A 82-year-old man presented with diarrhea and fatigue. He had no past medical or surgical history except chronic renal failure. Locally advanced rectal cancer with invasion to left ureter was detected in computed tomography. Colonoscopy revealed a circular lesion 12 cm from the anal verge. Biopsy showed moderately differentiated adenocarcinoma. There was no sign of distal metastasis and we decided to conduct radical surgery. Robot-assisted laparoscopic lower anterior resection with partial resection of left ureter, and diverting ileostomy were carried out. Besides, urinary tract reconstruction of ureterocystoneostomy using Lich-Gregoir technique was conducted by urologists also with robot assistance. The pathological stage of the disease was pT4b(left ureter)N1bM0, pStage Ⅲc. The resection margin was secured and radical surgery was achieved. The patient was discharged on postoperative day 22nd without postoperative complication. He is alive without recurrence at 6 months after the operation.

Abstract
Background There are only few reported cases of remnant gastric cancer with concomitant afferent loop syndrome. Emergency surgery is the standard treatment strategy for this disease. However, some afferent loop syndrome cases, especially those with complete obstruction, can lead to a septic state, which makes performing emergency surgery risky. We describe a case of remnant gastric cancer with complete afferent loop obstruction, which was successfully managed by radical surgery following percutaneous transhepatic cholangial drainage of the afferent loop. Case presentation A 71-year-old man presented with nausea and abdominal discomfort. When he was 27 years old, he had undergone distal gastrectomy for a benign gastric ulcer, with gastrojejunostomy (Billroth II reconstruction). Abdominal computed tomography revealed thickening of the anastomosis site and significant dilation of the afferent loop. Gastrointestinal fiberscopy revealed advanced remnant gastric cancer at the anastomosis site, and the stoma of the afferent loop was completely obstructed. We diagnosed the patient with remnant gastric cancer with afferent loop syndrome. Percutaneous transhepatic cholangial drainage was performed twice before surgery to decompress the afferent loop. This provided more time for the patient to recover. Radical surgery of total remnant gastrectomy and Roux-en-Y reconstruction were performed electively. There were no severe postoperative complications. The patient died 8 months following the operation owing to peritoneal dissemination recurrence. Conclusion We encountered a case of remnant gastric cancer with afferent loop obstruction, which was successfully managed by radical surgery following decompression of the afferent loop by percutaneous transhepatic cholangial drainage. Percutaneous transhepatic cholangial drainage effectively managed the afferent loop syndrome, resulting in the safe performance of elective surgery.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease, and multimodal strategies, such as surgery plus neoadjuvant chemotherapy (NAC)/adjuvant chemotherapy, have been attempted to improve survival in patients with localized PDAC. To date, there is one prospective study providing evidence for the superiority of a neoadjuvant strategy over upfront surgery for localized PDAC. However, which NAC regimen is optimal remains unclear. METHODS A randomized, exploratory trial is performed to examine the clinical benefits of two chemotherapy regimens, gemcitabine plus S-1 (GS) and gemcitabine plus nab-paclitaxel (GA), as NAC for patients with planned PDAC resection. Patients are enrolled after the diagnosis of resectable or borderline resectable PDAC. They are randomly assigned to either NAC regimen. Adjuvant chemotherapy after curative resection is highly recommended for 6 months in both arms. The primary endpoint is tumor progression-free survival time, and secondary endpoints include the rate of curative resection, the completion rate of protocol therapy, the recurrence type, the overall survival time, and safety. The target sample size is set as at least 100. DISCUSSION This study is the first randomized phase II study comparing GS combination therapy with GA combination therapy as NAC for localized pancreatic cancer. TRIAL REGISTRATION UMIN Clinical Trials Registry UMIN000021484 . This trial began in April 2016.

Abstract
AIM The impact of sustained virologic response (SVR) on surgical outcomes for patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) remains controversial. This study aimed to evaluate the influence of SVR on long-term surgical outcomes after hepatectomy. METHODS This multicenter study included 504 patients who underwent curative resection for HCV-related HCC. Patients with a history of HCC treatment, HBV infection, poor liver function, and tumor with major vascular invasion were excluded. Long-term surgical outcomes (overall survival [OS] and recurrence-free survival [RFS]) among patients who achieved SVR before hepatectomy (Pre-SVR group: 58 patients), after hepatectomy (Post-SVR group: 54 patients), and without SVR (Non-SVR group: 186 patients) were compared after adjusting for 13 confounding factors. Using the surgically resected specimens, comparison of the pathological changes in liver fibrosis between the first and second hepatectomy were analyzed. RESULTS Patients with SVR were younger, had better liver function, and less liver fibrosis compared to patients without SVR. Propensity score-matched OS and RFS were significantly better in Pre-SVR group than Non-SVR group (P = .029 and P = .009, respectively). Inverse probability-weighted OS and RFS were also significantly better in the Post-SVR group (P = .001 and P = .021, respectively) than in the Non-SVR group. Histopathological evaluation revealed that only the patients with SVR had regression of liver fibrosis (P < .05). CONCLUSION Achievement of SVR before or after hepatectomy is essential for improving long-term surgical outcomes in patients with HCV-related HCC.

Abstract
BACKGROUND Intraductal papillary mucinous neoplasm (IPMN) is a premalignant cystic neoplasm of the pancreas and is frequently detected in imaging investigations. A proportion of the patients with IPMN develop malignancies including high-grade dysplasia and invasive carcinoma. To predict the presence of malignancies in IPMN, constant imaging follow-up is usually required. Pancreatic steatosis (PS) has been recently identified as a facilitating factor for pancreatic cancer, and can be predicted through computed tomography (CT). We hypothesized that the CT-number of the pancreatic parenchyma could be a new reliable imaging biomarker for IPMN patients. METHODS Eighty-six patients undergoing pancreatectomy for IPMN were investigated. Using preoperative CT, the pancreatic index (PI) was calculated by dividing the CT-number of the pancreas by that of the spleen. RESULTS Malignancies were pathologically detected in 63 cases (73.3%). Patients were divided into two cohorts according to the presence of malignancies and were compared for various factors including the PI scores. The comparison of the two cohorts detected significant differences in two parameters (CA19-9 and PI score), and the PI score was the most sensitive biomarker to predict the presence of malignancies in patients showing high-risk stigmata of IPMN. CONCLUSIONS Pancreatic CT-number is an additional reliable imaging biomarker in distinguishing patients with IPMN having malignancies when investigating the patients showing high-risk stigmata.

Abstract
A man in his 50s was admitted to our hospital due to hematemesis.Esophagogastroduodenoscopy revealed an 8 cm type 2 gastric tumor.The tumor was histologically diagnosed as a neuroendocrine carcinoma.CT showed that the tumor had directly infiltrated the liver but there was no distant metastasis.We performed open distal gastrectomy, D2 lymph node dissection, partial hepatectomy, and cholecystectomy.Four months after the surgery, metastases of the right adrenal gland and dorsal part of the inferior vena cava were found.Although a significant tumor reduction was obtained by 12 courses of chemotherapy with CDDP plus CPT-11, this effective treatment was discontinued for the patient's convenience.Fifteen months after the surgery, metastasis of the right adrenal gland and dorsal part of inferior vena cava demonstrated re-growth without any further metastasis.After 4 courses of the same regimen, a partial response was obtained for the recurrences.As a salvage surgery, we performed open right adrenal gland and the lymph nodes of dorsal of IVC resection.The patient is alive without recurrence 1 year after the salvage surgery.

Abstract
There are few reports of using oxaliplatin(L-OHP)for esophageal squamous cell carcinoma.We report a case of long-term disease control after administration of L-OHP for esophagogastric junction squamous cell carcinoma(EG).A woman in her 40s was diagnosed with EG(cT3, cN2, cM0, cStage Ⅲ).She received thoracoscopic, laparoscopic-assisted, subtotal esophagectomy with 3-field dissection after 3 courses of preoperative chemotherapy with DCF(docetaxel hydrate, cisplatin, 5- fluorouracil).Reconstruction was achieved using a retrosternally shifted gastric tube and transesophageal gastro-tubing. Pathological examination showed EG(ypT3, ypN2, ypM0, ypStage Ⅲ)(chemotherapy evaluation: Grade 1a).After 12 months, para-aortic lymph node recurrence(#112aoP, #16a2lat)was observed on a follow-up CT examination.First, we administered 5 courses of chemotherapy with SOX(S-1 100mg/m2 day 1-14 and L-OHP 100 mg/m2 day 1).Recurrent lymph nodes shrunk slightly, and there were no new lesions.Subsequently, there was no other adverse event except for Grade 1 chemotherapy-induced neuropathy.Second, we administered 3 courses of chemotherapy with FOLFOX(5-FU 400mg/m2, L-OHP 85mg/m2, Leucovorin 200 mg/m2 day 1, 5-FU 1,600mg/m2/46 hr)in combination with radiotherapy(total 60 Gy/ 30 Fr).Recurrent lymph nodes shrunk slightly, and there were no new lesions.Subsequently, there was no other adverse event except for Grade 1 chemotherapy-induced neuropathy.No new recurrence was observed 19 months after the first recur- rence.The patient continues to receive weekly nab-PTX(85mg/m2).A regimen that includes L-OHP is useful in the treatment of advanced or recurrent esophageal squamous cell carcinoma.

Abstract
A woman in her 40s was hospitalizedfor jaundice. Six years before, she hadbeen diagnosedwith synchronous esophageal andgastric cancers andhadund ergone subtotal esophagectomy andtotal gastrectomy, accompaniedby reconstruction with the pedicled jejunum. Multimodal imaging revealed a tumor at the pancreatic head, probably pancreatic cancer, which induced severe stenosis of the intrapancreatic bile duct. Scraping cytology findings of the lesion via the percutaneous transhepatic cholangial drainage(PTCD)route strengthenedthe suspicion. In the image, although no obvious invasion of the major vessels or apparent distant metastases were detected, an abnormal shadow was found continuously lining the main tumor andpara -aortic region, which was a contraindication for curative resection. Therefore, we performed neoadjuvant chemotherapy with gemcitabine plus S-1. After 3 courses, the lesion size reduced notably, and pancreatoduodenectomy was performed. The pathological diagnosis was pancreatic cancer(ph, ypT3, ypN1a, ypM0, ypStage ⅡB). Except for pancreatic fistulas(Clavien-Dindo Ⅲa), the postoperative clinical course was uneventful, andshe was dischargedon postoperative day 27. To date, the patient is alive without recurrence and is undergoing adjuvant chemotherapy with S-1.

Abstract
Case 1: A man in his 70s was referred to our hospital for further examination of a liver tumor(S3, 3 cm)detected by ultrasonography. Multimodal image examination showed a cystic lesion with solid papillary components located in the S4 accompanied by dilatation of the surrounding intrahepatic bile duct. Although biliary cytology did not indicate confirmed malignancy, the lesion was thought to be an intraductal papillary neoplasm of bile duct(IPNB)with malignant potential, and a left lobectomy was performed. Histopathological examination revealed a papillary tumor in the intrahepatic bile duct which consisted of atypical epithelial cells of pancreatobiliary type, and the lesion was diagnosed as an IPNB with high-grade intraepithelial neoplasia. Case 2: A woman in her 70s was referred to our hospital because of a liver tumor(S4, 8 cm)detected by ultrasonography. Multimodal image examination showed a cystic lesion localized to the liver(S3, 8 cm), and endoscopic retrograde cholangiopancreatography(ERCP)showed continuity of the cyst and the intrahepatic bile duct. The biliary cytology was positive, and the lesion was thought to be a malignant IPNB. After preoperative drainage of the cystic lesion, a left lobectomy was conducted. Histopathological examination showed that the papillary tumor localized to the bile duct and atypical epithelium cells of pancreatobiliary type were infiltrating into the surrounding matrix. We diagnosed this tumor as an IPNB with an associated invasive carcinoma.

Abstract
A 78-year-old man who underwent esophagectomy for middle thoracic esophageal squamous cell carcinoma(pT1bN0M0, pStage Ⅰ)was diagnosed with lymph node recurrence 12 months after the initial surgery. He received chemoradiotherapy(5- fluorouracil plus cisplatin); however, the treatment was terminated at the middle of the treatment course because of progressive disease. He received chemotherapy(docetaxel plus 5-fluorouracil plus cisplatin)as a second-line treatment, which was also canceled due to serious adverse events. Partial response was achieved after the second therapy; therefore, surgical excision was performed. Thirteen months after the second surgery, he was diagnosed with second local recurrence with invasion to the trachea. Another course of chemotherapy(docetaxel[2-weekly]plus 5-fluorouracil plus cisplatin)was administered, which also achieved a partial response. Thus, surgical excision with partial tracheal resection and mediastinal tracheostomy was performed. He has been alive without recurrence for 6 months after the final operation. In case of postoperative solitary lymph node recurrence of esophageal cancer, long-term survival can be expected with multidisciplinary treatment.

Abstract
BACKGROUND AND AIM There are no previous reports describing the prognostic significance of the residual intraductal carcinoma component (carcinoma in situ [CIS]) following preoperative treatment for pancreatic ductal adenocarcinoma (PDAC). The aim of the present study was to investigate the prognostic significance of a minimal residual CIS in cases with complete absence of an invasive component after preoperative treatment for PDAC. METHODS Eighty-one of 594 PDAC patients with preoperative treatment and subsequent surgery in our institute showed remarkable remission in the invasive component, which included 48 patients with the minimal residual invasive component (Min-inv group) and 33 with absence of an invasive component (No-inv group). We assessed the survival of these patients in association with the presence or absence of an invasive component and intraductal CIS. RESULTS Five-year overall survival in the No-inv group patients was significantly better than that of the Min-inv group patients (82%/66%, P = .041). Among the 33 patients in the No-inv group, residual CIS was observed in 16 patients (CIS-positive group), and the remaining 17 patients had no residual CIS (CIS-negative group). There was no significant difference in survival between patients in the CIS-positive and CIS-negative groups (92%/78%, P = .31). CONCLUSIONS Residual CIS in the absence of an invasive component after preoperative treatment does not yield a prognostic impact after receiving perioperative treatment for PDAC. It might be reasonable to define pathological complete response (pCR) from the prognostic standpoint as follows: pCR is the complete absence of an invasive carcinoma component regardless of residual CIS.

Abstract
PURPOSE Neoadjuvant chemotherapy (NAC) followed by surgery is a promising treatment strategy for patients with advanced gastric cancer. Severe toxicity associated with the treatment may reduce the dose intensity of chemotherapy, resulting in the effect of chemotherapy being attenuated. Recently, skeletal muscle mass has been reported to be associated with the treatment outcomes of cancer patients. The purpose of this study was to clarify whether pretreatment skeletal muscle mass is a predictor of adverse events as well as the relationship between changes in skeletal muscle mass and adverse events during NAC. METHODS This study included 41 advanced gastric cancer patients who were treated with NAC followed by surgery. Body composition was assessed before and after NAC. The relationship between the pre-NAC body composition and adverse events was investigated as well as the relationship between changes in body composition and adverse events. RESULTS Univariate and multivariate analyses revealed that low pre-NAC skeletal muscle mass was the only factor significantly associated with severe diarrhea (p = 0.03). There was no significant difference in body weight before and after NAC, but skeletal muscle mass was significantly reduced after NAC (-5.93 ± 7.69%, p < 0.01). Furthermore, patients who experienced severe diarrhea showed significantly greater relative skeletal muscle decrease than those who did not (p = 0.03). CONCLUSIONS Pre-NAC low skeletal muscle mass was a useful predictor of severe diarrhea. Prevention of severe adverse events may contribute to maintaining the skeletal muscle mass.

Abstract
BACKGROUND & AIMS Neoadjuvant chemoradiotherapy (NACRT) for pancreatic cancer (PC) is potentially associated with various toxicities, which can lead to impaired nutritional status. Eicosapentaenoic acid (EPA) can reduce proinflammatory cytokines and positively influence cancer cachexia syndrome. The aim of this study is to clarify the utility of EPA enriched nutrition support during NACRT for PC. METHODS We randomly assigned 62 patients with PC that received NACRT to either a nutrition intervention (NI) or a normal diet (ND). Patients in the NI group received 2 bottles/day (550 kcal/day) of an EPA-enriched nutrition supplement during NACRT. The primary endpoints were the before-to-after NACRT ratios (post/pre ratios) of skeletal muscle mass and psoas major muscle area (PMA). The secondary endpoints were the post/pre ratios of other nutritional parameters and treatment-related toxicities. RESULTS Only 14 patients (45.2%) in the NI group consumed more than 50% of the EPA-enriched supplement provided. The post/pre ratio of skeletal muscle mass in the NI group (0.99 ± 0.060) was not significantly different from that of the ND group (0.96 ± 0.079, p = 0.102). However, patients that consumed ≥50% of the EPA-enriched supplement (the good intake group) had significantly higher skeletal muscle mass ratios than patients in the ND group (p = 0.042). The PMA ratio was significantly higher in the NI group (0.96 ± 0.081) than in the ND group (0.89 ± 0.072, p = 0.001). The NI and ND groups were not significantly different in other nutritional parameters or in NACRT-related toxicity. CONCLUSIONS We found that EPA-enriched intake could potentially improve the nutritional status of patients with PC that received NACRT, but it was difficult for many patients to drink, due to its disagreeable taste.

Abstract
Although the preoperative endoscopic marking method using dye is widely used, the dye can spread into the tissue or abdominal cavity, inducing the inflammation and leading to the wrong dissection. We developed a novel marking method using an endoscopic clip with a light emitting diode (LED) and a power source device to detect the accurate location of the site of interest. We performed this new marking method in three patients with gastrointestinal cancers. We placed an endoscopic clip with an LED on the gastrointestinal mucosa and used a power source device outside of the human body to detect the LED. We detected the clip with the LED using the power source device. We also confirmed the usefulness of this clip in three of three (100%) patients with colorectal and gastric cancer. We developed a novel marking device using an LED to identify an objective location successfully.

Abstract
BACKGROUND/AIM The association between the presence of sarcopenia and systemic inflammatory response is unclear in patients with esophageal cancer. This study was performed to investigate the relationship between sarcopenia and systemic inflammatory response and clarify the effect of these factors on the prognosis in patients with esophageal cancer. PATIENTS AND METHODS This study included 163 patients with esophageal cancer. The patients' body composition was assessed before esophagectomy using multifrequency bioelectrical impedance. The relationship between sarcopenia and inflammatory factors were investigated before surgery. RESULTS Sarcopenia was significantly associated with a high C-reactive protein-to-albumin (CRP/Alb) ratio (p=0.046). Patients with sarcopenia significantly associated with worse overall survival (OS) (p=0.025) and tended to show a worse recurrence-free survival (RFS) (p=0.065). A high CRP/Alb ratio was significantly associated with worse OS and RFS. Multivariate analysis revealed that among all inflammatory factors, only a high CRP/Alb ratio was an independent prognostic factor for RFS (p=0.022). CONCLUSION Sarcopenia is associated with systemic inflammatory response such as high CRP/Alb ratio, while the latter is an independent prognostic marker in patients with esophageal cancer.

Abstract
BACKGROUND Several studies have reported that modified Collard anastomosis is useful for cervical anastomosis after esophagectomy for thoracic esophageal cancer. However, no large-scale study has confirmed the efficacy of the modified Collard anastomosis. METHODS Between 2008 and 2016, 398 consecutive esophageal cancer patients who underwent esophagectomy and cervical anastomosis were enrolled in this study. Patients with a short remnant cervical esophagus were excluded. We investigated the utility of the modified Collard anastomosis by comparing the results of postoperative complications using a propensity score-matched analysis between the hand-sewn method (HS) and the modified Collard anastomosis (MC) for esophagogastric anastomosis of the neck after esophagectomy in thoracic esophageal cancer patients. RESULTS Of the 398 patients, 127 were included in the MC group and 127 were included in the HS group after propensity score matching. Clinical characteristics did not differ between the two groups. Frequency of anastomotic leakage tended to be lower in the MC group than in the HS group (3% vs. 7%, P = 0.127). Frequency of anastomotic stenosis was significantly lower in the MC group than in the HS group (13% vs. 59%, P < 0.001). Multivariate logic analysis showed that anastomotic technique (HS) and performance status were independent factors associated with anastomotic stenosis (odds ratio, 12.24 and 2.52; P-value <0.001 and 0.047, respectively). CONCLUSION In cervical esophagogastric anastomosis after esophagectomy, the modified Collard anastomosis is more suitable than hand-sewn anastomosis in terms of reducing the frequency of anastomotic stenosis.

Abstract
AIM The aim of the present study was to examine the usefulness of a perioperative bacteriological culture in predicting the pathogenic bacteria responsible for postoperative pneumonia after esophagectomy. METHODS This study included 293 consecutive esophageal cancer patients who underwent esophagectomy with gastric conduit reconstruction. We compared the pathological bacteria that were detected in bacteriological cultures of sputum, mouthwash and gastric fluid on the second postoperative day with the pathogenic bacteria responsible for postoperative pneumonia. RESULTS Postoperative pneumonia occurred in 26 (8.8%) of the 293 patients. Enterobacter cloacae was detected most frequently in the perioperative bacteriological culture, followed by Enterococcus faecalis and Pseudomonas aeruginosa. Detection of each pathogenic bacterium in the perioperative bacteriological culture was not associated with the occurrence of pneumonia, excluding Pseudomonas aeruginosa. As the pathogens responsible for postoperative pneumonia, 32 bacteria were detected in 26 patients with postoperative pneumonia. Detection rate of the pathogenic bacteria responsible for postoperative pneumonia in a perioperative bacteriological culture was 43.8% in a sputum culture, 40.6% in a mouthwash culture and 65.6% in a gastric fluid culture. The detection rate of the pathogenic bacteria responsible for pneumonia was up to 78.1% in the combination of sputum and gastric fluid culture. CONCLUSIONS Although the perioperative bacteriological culture does not seem to be useful for predicting the occurrence of postoperative pneumonia, it is useful for predicting the pathogenic bacteria responsible for pneumonia in cases of postoperative pneumonia. The perioperative bacteriological culture helps us to select appropriate antibiotics to treat pneumonia after esophagectomy.

Abstract
BACKGROUND Preoperative chemoradiation therapy is a promising strategy for pancreatic cancer. Peritoneal recurrence is a major recurrence pattern after surgery for pancreatic cancer following preoperative chemoradiation therapy, even in patients with negative peritoneal lavage fluid cytology. Previous reports have indicated that the detection of carcinoembryonic antigen mRNA by reverse transcription polymerase chain reaction is useful for evaluating subclinical tumor cell dissemination in peritoneal lavage fluid. METHODS Patients with resectable and borderline resectable pancreatic cancer treated with preoperative gemcitabine-based chemoradiation therapy and subsequent surgery were enrolled in this study. In all patients, a conventional cytologic examination of peritoneal lavage fluid from laparotomy confirmed the negative peritoneal cytology status. Carcinoembryonic antigen mRNA was detected in the peritoneal lavage fluid at laparotomy using reverse transcription polymerase chain reaction. Recurrence patterns and survival were evaluated in association with the carcinoembryonic antigen mRNA status in the peritoneal lavage fluid. RESULTS The peritoneal lavage fluid from 57 of the 237 patients (24%) was carcinoembryonic antigen mRNA(+). The carcinoembryonic antigen mRNA(+) patients had a significantly higher incidence of peritoneal recurrence than the carcinoembryonic antigen mRNA(-) patients (36% vs. 15%, P < .001). The 5-year survival rates of the carcinoembryonic antigen mRNA(+) and carcinoembryonic antigen mRNA(-) patients were 31% and 51%, respectively (P = .037). A multivariable analysis for survival revealed that borderline resectability, positive nodal status, and positive carcinoembryonic antigen mRNA status were independent variables for impaired survival. CONCLUSION Carcinoembryonic antigen mRNA(+) status was associated with a significantly increased incidence of peritoneal recurrence in patients with pancreatic cancer treated with preoperative chemoradiation therapy, resulting in impaired survival.

Abstract
We report the case of a 72-year-old man who was initially diagnosed with far advanced intrahepatic cholangiocarcinoma, associated with bulky lymph node metastasis involving the common hepatic artery and moderate amount of ascites around the liver. After 10 cycles of systemic chemotherapy combining gemcitabine and S-1 with well-tolerated toxicities, a CT scan showed a marked shrinkage of the liver mass and lymph nodes (clinical partial response) with disappearance of ascites, which could permit a radical resection of the tumor. He underwent left lobectomy of the liver with lymph node dissection, and histopathological examination revealed pathologic complete response. Seven years after surgery, he is in a good overall condition.
