Abstract
BACKGROUND Although intracorporeal anastomosis (IA) for colon cancer requires longer operative time than extracorporeal anastomosis (EA), its short-term postoperative results, such as early recovery of bowel movement, have been reported to be equal or better. As IA requires opening the intestinal tract in the abdominal cavity under pneumoperitoneum, there are concerns about intraperitoneal bacterial infection and recurrence of peritoneal dissemination due to the spread of bacteria and tumor cells. However, intraperitoneal bacterial contamination and medium-term oncological outcomes have not been clarified. AIM To clarify the effects of bacterial and tumor cell contamination of the intra-abdominal cavity in IA. METHODS Of 127 patients who underwent laparoscopic colon resection for colon cancer from April 2015 to December 2020, 75 underwent EA (EA group), and 52 underwent IA (IA group). After propensity score matching, the primary endpoint was 3-year disease-free survival rates, and secondary endpoints were 3-year overall survival rates, type of recurrence, surgical site infection (SSI) incidence, number of days on antibiotics, and postoperative biological responses. RESULTS Three-year disease-free survival rates did not significantly differ between the IA and EA groups (87.2% and 82.7%, respectively, P = 0.4473). The 3-year overall survival rates also did not significantly differ between the IA and EA groups (94.7% and 94.7%, respectively; P = 0.9891). There was no difference in the type of recurrence between the two groups. In addition, there were no significant differences in SSI incidence or the number of days on antibiotics; however, postoperative biological responses, such as the white blood cell count (10200 vs 8650/mm3, P = 0.0068), C-reactive protein (6.8 vs 4.5 mg/dL, P = 0.0011), and body temperature (37.7 vs 37.5 °C, P = 0.0079), were significantly higher in the IA group. CONCLUSION IA is an anastomotic technique that should be widely performed because its risk of intraperitoneal bacterial contamination and medium-term oncological outcomes are comparable to those of EA.

Abstract
A 71-year-old woman was found to have submucosal tumor-like lesion on colonoscopy (CS) before gastric surgery, and computed tomography (CT) showed a 12-mm structure at the base of the appendix. The lesion could not be clearly detected on CT nine months later, but it had enlarged again on CT one year later; therefore, CS and endoscopic ultrasound (EUS) were performed. The lesion was determined to be cystic with viscous contents, and laparoscopic appendicectomy was performed. This is the first report of low-grade appendiceal mucinous neoplasm (LAMN) diagnosed by a histopathologic examination of a resected specimen showing shrinkage and re-expansion of the appendix.

Abstract
An 87-year-old man experiencing lower abdominal discomfort resulting from the ingestion of a fish bone underwent conservative management involving endoscopic extraction of the fish bone lodged in the sigmoid colon. Most patients with lower gastrointestinal tract perforations typically develop peritonitis or abscesses, necessitating surgical intervention. Notably, endoscopic management of lower gastrointestinal tract perforations is infrequently employed. Patients presenting with localized abdominal symptoms along with a stable overall health condition may benefit from conservative therapeutic approaches that utilize endoscopic methods. Notably, the transition from endoscopic procedures for foreign body removal to surgical intervention requires close collaboration with a surgeon and must be executed judiciously.

Abstract
A 72-year-old man with type 2 sub-circumferential tumors in the descending colon and two nodules around the pedicle of the inferior mesenteric artery (main lymph node area) underwent laparoscopic left hemicolectomy with D3 lymphadenectomy. Two lymph nodes around the inferior mesenteric artery pedicle were completely excised. Pathological examination revealed a moderately differentiated tubular adenocarcinoma. Nodules were only found in the main lymph node area, and no lymph node structures were observed in these nodules. These tumor deposits (TDs) may be extramural TDs without lymph node structure or lymph node skip metastasis. The presence of TDs in colorectal cancer is associated with an adverse prognosis, and the requirement of chemotherapy in such cases should be examined. Therefore, it is important to correctly recognize TDs and categorize the disease into a high- or low-risk group within stage III. We report this case because it is necessary to review the definition of TDs, and the assessment of extramural TDs remains controversial.

Abstract
Background Despite numerous reports on ischemic bowel obstruction caused by internal hernia, no case presentation has been reported of an internal hernia caused by a bridge formed between the medial and lateral zones of the liver. Herein, we report the first case of ischemic bowel obstruction caused by a hepatic bridge. Case presentation A 24-year-old man complaining of abdominal pain was referred to our hospital and admitted. Computed tomography showed formation of a closed loop of small bowel with a hernia orifice near the hilar region, and poor contrast of the prolapsed small bowel. We suspected ischemic bowel obstruction caused by an internal hernia with a fissure of the greater omentum as the hernia orifice, and performed emergency surgery. Laparoscopic observation revealed that the medial and lateral segments of the liver formed a bridge on the dorsal side at the liver portal, and that the small intestine was ischemic in the gap created between the bridge and the medial and lateral liver segments. A Meckel’s diverticulum was also invaginated in the gap. The bridge was dissected out and the hernia orifice was opened to release the bowel obstruction. The small bowel was preserved and the Meckel’s diverticulum was resected. The patient’s postoperative course was uneventful. Conclusions We experienced a case of ischemic bowel obstruction caused by hepatic bridge formation, which was successfully treated by laparoscopic surgery.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (nCRT) followed by total mesorectal excision surgery is a standard treatment for locally advanced rectal cancer (LARC). Tumor-infiltrating lymphocytes (TILs) have been reported to be associated with tumor response; however, this remains to be established. We previously reported that histological changes on biopsy specimens obtained 7 days after starting nCRT are strong predictors of response to nCRT. METHODS The subjects were 208 patients with LARC who received nCRT. TILs on hematoxylin-eosin staining together with immunohistochemical staining of lymphocyte surface markers including CD3, CD4, CD8, and FoxP3 were performed both on the biopsy specimens before and 7 days after starting nCRT. RESULTS The proportions of patients with high densities of CD3+, CD4+, CD8+, and FoxP3+ cells 7 days after starting CRT were significantly lower than the respective values before starting nCRT (p < 0.0001, p < 0.0001, p = 0.0023, and p = 0.0046). In biopsy specimens obtained before treatment, high-density CD4+ cells and FOXP3+ cells were significantly associated with tumor shrinkage rate. High-density FOXP3+ cells were significantly associated with marked tumor regression. In biopsy specimens obtained 7 days after starting treatment, high-density CD4+ cells were significantly associated with marked tumor regression, tumor regression grade 1, and tumor shrinkage rate. High-density FoxP3+ cells were significantly associated with marked tumor regression and tumor shrinkage rate. CONCLUSIONS In patients who received nCRT for LARC, the evaluations of immunohistochemical staining for CD4+ and FOXP3+ TILs were more intimately related to histological response to CRT and tumor shrinkage rates in biopsy specimens obtained 7 days after starting treatment than in biopsy specimens obtained before CRT.

Abstract
BACKGROUND FOLFIRI plus bevacizumab have been widely used as first-line treatment for metastatic colorectal cancer (mCRC). Pharmacokinetics and pharmacodynamics suggested a low dose of irinotecan given as a long-term infusion is expected to enhance antitumor activity. We conducted a randomized phase II study to compare oral S-1 with a 24-h infusion of irinotecan plus bevacizumab versus FOLFIRI plus bevacizumab. METHODS The subjects comprised 120 chemotherapy-naïve patients with mCRC. The study group received a 24-h infusion of irinotecan at a dose of 125 mg/m2 on days 1 and 15, combined with oral S-1 80 mg/m2 on days 1-14 (24h-SIRI/B). The FOLFIRI/B group received irinotecan at a dose of 150 mg/m2, 5-fluorouracil given at a dose of 400 mg/m2 as a bolus injection and at a dose of 2,400 mg/m2 as a 46-h infusion, and 200 mg/m2 leucovorin on days 1 and 15. Bevacizumab was given at a dose of 5.0 mg/kg on days 1 and 15 in both groups. Treatment was repeated every 4 weeks. The primary endpoint was 1-year progression-free survival (PFS). Secondary endpoints were PFS, response rates (RR), overall survival (OS), and adverse events (AEs). RESULTS From December 2013 through January 2018, 120 patients were randomly assigned, 61 patients to the 24h-SIRI/B and 59 patients to the FOLFIRI/B. The median follow-up period was 22.8 months. The 1-year PFS rate was 43.14% in the 24h-SIRI/B arm and 19.15% in the FOLFIRI/B arm (HR = 0.312 [95%CI 0.13-0.78], p = 0.01). The median PFS was 10.2 months (95%CI 8.8-14.3) and 10.0 months (95%CI 7.4-11.0), and the median OS was 29.7 months (95%CI 22.9-43.9) and 28.8 months (95%CI 18.4-ND), respectively (p = 0.3758, p = 0.8234). The overall RR was 86.3 and 61.7%, respectively (p = 0.0053). AEs were similar. CONCLUSIONS Our results show that the 24h-SIRI/B regimen is an effective and reasonably well-tolerated regimen for the first-line treatment of mCRC.

Abstract
BACKGROUND Colorectal neuroendocrine carcinoma (NEC) is a rare disease, and mixed cases with colorectal adenocarcinoma also exist. The histogenesis of this disease remains unclear. We studied the numbers of neuroendocrine marker-positive cells in adenocarcinoma tissue and in normal -mucosal tissue to investigate the relation between adenocarcinoma and NEC and to discuss the histogenesis of NEC. METHODS We studied a total of 354 curatively resected cases of stage II or III colon cancer and 36 cases of rectal cancer treated at the Tokai University Hospital between 2007 and 2012. Adenocarcinoma tissue and normal mucosal tissue were immunohistochemically stained with chromogranin A, synaptophysin, and CD56. Cases in which neuroendocrine marker-positive cells were found in cancer tissue were defined as positive. In normal mucosa, the numbers of positive cells per 15 high-power fields (HPF) were counted. RESULTS Among the 390 cases, 181 cases had right sided colon cancer, 173 cases had left sided colon cancer, and 36 cases had rectal cancer. The rates of positive staining for chromogranin A, synaptophysin, and CD56 were significantly higher in the right sided colon than in the left sided colon, consistent with the preferred sites of NEC as reported previously. Cells positive for chromogranin A and synaptophysin in normal mucosa were significantly more common in the rectum and the left sided colon than in the right sided colon. No site-specific differences were found for CD56. CONCLUSIONS Neuroendocrine marker-positive cells in colorectal cancer tissue are more common in the right sided colon, whereas neuroendocrine marker-positive cells in normal mucosa are more common in the rectum. These results suggest that NEC may arise from preceding adenocarcinomas.

Abstract
BACKGROUND To prevent surgical site infection (SSI) in colorectal surgery, the combination of mechanical bowel preparation (MBP), oral antibiotic bowel preparation (OABP), and the intravenous antibiotics have been proposed as standard treatment. We conducted an RCT comparing the incidence of SSI between MBP + OABP and OABP alone after receiving a single dose of intravenous antibiotics. METHODS The study group comprised 254 patients who underwent elective surgery for colon cancer. Patients were randomly assigned to receive MBP + OABP and intravenous antibiotics (MBP + OABP group) or to receive OABP and intravenous antibiotics (OABP alone group). RESULTS Overall, 125 patients in MBP + OABP group and 126 patients in OABP alone group were eligible. Incisional SSI occurred in 3 patients (2.4%) in MBP + OABP group, and 8 patients (6.3%) in the OABP-alone group. Organ/space SSI developed in 0 patients (0%) and in 4 patients (3.2%) in each group respectively. The OABP-alone group was thus not shown to be noninferior to the MBP + OABP group in the incidences of incisional SSI or organ/space SSI. Other infectious complications developed in 7 patients (5.6%) and in 6 patients (4.8%) in each group, indicating the non-inferiority of OABP alone to MBP + OABP. CONCLUSIONS MBP combined with oral antibiotics and intravenous antibiotics remains standard in elective colon cancer surgery.

Abstract
613 Background: FOLFOX or FOLFIRI plus Bev is a first-line treatment for MCRC. Recent studies have confirmed that oral S-1 combined with Iri and Bev is equivalent to FOLFIRI plus Bev. Iri is usually administered as a short-term 90-min. infusion. However, the cytocidal activity is S-phase specific, and carboxylesterases, that convert Iri into SN-38, are less likely to become saturated when Iri is given as a long-term infusion. Therefore, a low dose of Iri given as a long-term infusion is expected to enhance antitumor activity. We conducted a randomized phase II study to compare this regimen with FOLFIRI plus Bev. Methods: The subjects comprised 120 chemotherapy-naïve patients with MCRC. The study group received 24-hr infusion of Iri at a dose of 125 mg/m2 on days 1 and 15, combined with oral S-1 80 mg/m2 on days 1 to 14. The FOLFIRI group received Iri at a dose of 150 mg/m2, 5-FU given at a dose of 400 mg/m2 as a bolus injection and at a dose of 2400 mg/m2 as a 46 hr-infusion, 200 mg/m2 of leucovorin on days 1 and 15. Bev was given at a dose of 5.0 mg/kg on days 1 and 15 in both groups. Treatment was repeated every 4 weeks. The primary endpoint was the 1 y progression-free survival (PFS). Secondary endpoints were PFS, response rates (RR), overall survival (OS), and adverse events (AEs). Results: From October 2013 through December 2017, a total of 61 patients assigned to receive IRIS plus Bev (the A group) and 59 patients assigned to receive FOLFIRI plus Bev (the B group) were included in the analysis. The 1y RFS was 37.3% in the A group and 17.0% in the B group (p = 0.0281). The PFS was 10.2 mon in the A group and 10.0 mon in the B group, and the median OS was 27.0 mon and 28.6 mon, respectively (p = 0.26, p = 0.68). RR was significantly higher in the A group (87.0%) than in the B group (61.7%) (p = 0.005). The main grade 3 or 4 AEs were neutropenia (27.8%) and diarrhea (11.1%) in the A group and neutropenia (23.4%) and leukopenia (6.4%) in the B group. Conclusions: Our results showed that Iri, given biweekly as a 24-hour infusion in combination with oral S-1 and Bev, is a highly effective and well-tolerated regimen for the first-line treatment of MCRC.

Abstract
617 Background: Neuroendocrine carcinoma (NEC) is a rare disease and has been reported to most frequently arise in the right side of the colon. In the 2010 WHO classification, mixed adenoneuroendocrine carcinoma (MANEC) was defined as a neoplasm consisting of NEC and adenocarcinoma components. To clarify the histogenesis of NEC, we attempted to detect neuroendocrine marker-positive cells in cancer tissue and in the adjacent mucosa in patients with adenocarcinoma. Methods: The study group comprised 390 patients with Stage II or III colorectal adenocarcinoma between 2007 and 2012. Immunostaining was performed with anti chromogranin A, synaptophysin, and CD56 antibodies. Cases with positively stained cells in cancer tissue were defined as positive. In the adjacent mucosa, at least 5 cm from the tumor, the numbers of positive cells per 15 HPF were measured. Results: Tumor location was right side in 181 patients, left side in 173, and the rectum in 36 patients. Positive rates of Chromogranin A in cancer tissues were 23.7% in the right colon, 13.2% in the left colon, and 19.4% in the rectum. Those of synaptopysin were 35.3%, 21.9%, and 30.6%, respectively. Those of CD56 were 22.6%, 8.0%, and 16.7%, respectively. Positive rates of these three markers in right colon were significantly higher than those in left colon and rectum. (p = 0.0115, p = 0.0054, p = 0.0062). In the adjacent mucosa, the mean numbers of positive cells for chromogranin A were 62.2 ± 20.5 in the right colon, 131.9 ± 44.7 in the left colon, and 243.7 ± 60.2 in the rectum (p < 0.001). Those for synaptophysin were 47.7 ± 23.5, 95.3 ± 35.1, and 156.9 ± 56.8, respectively. (p < 0.001). There were no significant differences in the number of positive cells for CD56 among the sites (p = 0.295). Conclusions: In cancer tissue, the rate of positive staining for neuroendocrine marker-positive cells was higher in the right side of the colon, whereas in normal mucosa the rates of positive staining for these cells were higher in the sigmoid colon and the rectum. These results suggest that neuroendocrine marker-positive cells are an acquired characteristic of cancer tissue.

Abstract
494 Background: In colon cancer, retrieval of less than 12 lymph nodes is a risk factor for recurrence. We previously reported that the long-axis diameter of the largest LNs (maximum LNs) is associated with a higher number of retrieved LNs and better outcomes in stage II disease (Int J Colorectal Dis 2015). Furthermore, the number of natural killer cells in the maximum LNs is associated with the number of retrieved LNs and lymph node size, and is an independent prognostic factor (Oncology 2018). We examined whether the long-axis diameter of maximum LNs with and without metastasis is a prognostic factor in stage III colon cancer. Methods: The study group comprised 190 patients with stage III colon cancer from 2005 to 2014. For each patient, one negative LN and one positive LN with the greatest long-axis diameter were selected, and the diameter was measured on H-E stained specimens. The endpoint of survival analysis was relapse free survival (RFS). The cut-off value (COV) was determined by using receiver operating characteristic curves. Results: The mean long-axis diameter of maximum negative and positive LNs were 8.5 ± 3.7 and 9.9 ± 4.9 mm, respectively. Factors related to the number of retrieved LNs were the tumor size (less than 4.3 cm, 13.5 ± 6.4; 4.3 cm or more, 16.6 ± 7.3; p = 0.004) and the long axis diameter of maximum negative LNs (< 8.1 mm, 13.4 ± 6.9; ≥ 8.1 mm, 17.6 ± 6.6; p < 0.001). Maximum negative LNs with a diameter of ≥ 8.1 mm was associated with significantly better RFS than maximum negative LNs with a diameter of < 8.1 mm (p = 0.020). The diameter of maximum positive LNs was not a prognostic factor. On multivariate analysis, the tumor size (≥ 4.3 cm/< 4.3 cm, HR 3.02; p < 0.001), venous invasion (absent/present, HR 0.41; p = 0.017), the number of LNs (≥ 12/< 12, HR 0.56; p = 0.043), and the diameter of maximum negative LNs (≥ 8.1 mm/< 8.1 mm, HR 0.45; p = 0.008) were independent prognostic factors. Conclusions: In stage III colon cancer, the long-axis diameter of negative maximum LNs was a prognostic factor. Enlarged negative LNs are caused by hyperplasia of cell components in LNs. The size of negative maximum LNs might reflect the tumor immunity of the host.

Abstract
The Torricelli-Bernoulli sign is a computed tomography (CT) finding that occurs when ulceration/necrosis of a submucosal gastrointestinal tumor releases a stream of air bubbles into the intestinal lumen. A 75-year-old man developed acute abdominal pain at night and presented to a local doctor. Acute abdomen was diagnosed and he was referred to the Emergency Department at Tokai University Oiso Hospital. On CT scans, disseminated intestinal tumor-like lesions were seen in the right lower abdomen. The Torricelli-Bernoulli sign and free intraabdominal gas were observed, so perforation of an intestinal tumor was diagnosed and emergency surgery was performed. At operation, there was scanty opaque ascites in the right lower abdomen and an ileal tumor associated with nodules that suggested peritoneal dissemination. Partial resection of the ileum was performed and peritoneal lavage was conducted. The patient was discharged on postoperative day 11. Histopathological examination revealed a high risk gastrointestinal stromal tumor. The abdominal nodules were metastases, indicating that the tumor was Stage IV. The patient is currently on treatment with an oral tyrosine kinase inhibitor (imatinib).

Abstract
OBJECTIVE We previously reported that the largest diameter of retrieved lymph nodes (LNs) correlates with the number of LNs and is a prognostic factor in stage II colon cancer. We examine whether T, B, and natural killer (NK) cells in LNs are related to the number of LNs and survival. METHODS The subjects comprised 320 patients with stage II colon cancer. An LN with the largest diameter was selected in each patient. The positive area ratios of cells that stained for CD3 and CD20, and the numbers of CD56-positive cells were measured. RESULTS The CD3-positive area ratio was 0.39 ± 0.08 and CD20-positive area ratio was 0.42 ± 0.10. The mean number of CD56-positive cells was 19.3 ± 22.7. The area ratios of B cells and T cells and the number of NK cells were significantly related to the sizes of the largest diameter LNs. The number of NK cells significantly correlated with the number of LNs and was an independent prognostic factor. On multivariate analysis, pathological T stage (T4 or T3; HR 4.71; p < 0.001) and the number of CD56-positive cells (high or low; HR 0.22; p < 0.001) were found to be independent prognostic factors. CONCLUSIONS The number of NK cells in the largest diameter LNs can most likely be used as a predictor of recurrence.

Abstract
BACKGROUND Mucinous rectal carcinoma has been reported to have a lower survival rate and a poorer histologic response to chemoradiotherapy(CRT). Magnetic resonance imaging (MRI) can accurately evaluate the amount of mucin pools (MP) in primary cancer tissue. We compared the degree of MP on MRI before and after CRT with the histologic findings of resected specimens to investigate the predictors of response to CRT. METHODS The study group comprised 205 patients with rectal adenocarcinoma who received preoperative CRT. MPs were measured on MRI before and after CRT and in resected specimens. The degree of MP was classified into five classes according to the MP area ratio: 0%, class I; 1 to 19%, class II; 20 to 49%, class III; and 50% or higher, class IV. RESULTS The degree of MP on MRI was largely unchanged after CRT; however, the MP on MRI after CRT was underestimated in 26.3% of patients as compared with that in resected specimens. A pathological complete response was obtained in patients who initially had no MP or had an MP ratio of less than 20%. The tumor volume was significantly greater, and the rates of tumor shrinkage and T downstaging were significantly lower in patients who had an MP area ratio of 20% or higher before CRT than in those who had an MP area ratio of less than 20%. CONCLUSIONS The MP area ratio measured on MRI before treatment was closely associated with the response to CRT and is a potentially useful predictor of treatment response.

Abstract
OBJECTIVES The histologic response to neoadjuvant chemoradiotherapy (nCRT) has been intimately related to outcomes in locally advanced rectal cancer. Serum carcinoembryonic antigen (CEA) levels change after nCRT and after surgery as compared with before nCRT. METHODS The subjects were 149 patients with locally advanced rectal cancer who received nCRT between 2005 and 2013. The patients were divided into 4 groups according to the serum CEA levels: group 1, 55 patients with negative serum CEA levels before nCRT; group 2, 41 patients with positive serum CEA levels before nCRT that became negative after nCRT; group 3, 37 patients with positive serum CEA levels after nCRT that became negative after surgery; and group 4, 16 patients with positive serum CEA levels after nCRT as well as after surgery. RESULTS Pathological complete response, T downstaging, and tumor shrinkage were significantly higher in group 1 than in other groups. Disease-free survival was significantly poorer in group 4. The lack of a decrease in the serum CEA level in group 4 was most likely attributed to the persistence of micrometastases outside the resection field. CONCLUSIONS Changes in serum CEA levels measured before nCRT, after nCRT, and after surgery can be used to reliably predict the histologic response to nCRT and outcomes.

Abstract
In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis. The liver metastasis became resectable after chemotherapy, with two resection procedures and radiofrequency ablation (RFA) being performed. Thereafter, lung metastasis occurred and a tumor in the left lung was resected. In May 2015, he developed respiratory distress. CT identified multiple lesions protruding into the lumen of the trachea and the left and right main bronchi. There was no evidence of mediastinal relapse or local relapse at the resection margin, and tumors were only detected in the tracheobronchial walls. Accordingly, narrow EM was diagnosed. An expandable metallic stent (EMS) was placed on the right side where stenosis was more severe, and radiation therapy was conducted for the non-stented tumors. The patient died 8 months later. Case 2: A 69-year-old woman had undergone laparoscopic right hemicolectomy and adjuvant chemotherapy for Stage lllb cancer of the ascending colon. Due to subsequent elevation of tumor markers, PET-CT was conducted and abnormal uptake was seen in the apex of the right lung and right upper abdomen. Both lesions were resected, and omental and lung metastases were diagnosed. She received treatment with UFT / calcium folinate, but relapse occurred at the resection margin in the right lung. At 7 years and 5 months after initial surgery, she complained of respiratory distress at an outpatient visit. CT demonstrated displacement of the trachea and right main bronchus due to enlargement of upper mediastinal lymph nodes. There was also severe stenosis of the right main bronchus due to tumor infiltration. Because there was both infiltration from local recurrence after resection and upper mediastinal lymph node enlargement, broad EM was diagnosed. An EMS was placed at the site of severe stenosis in the right main bronchus. Similar to Case 1, radiation therapy was also conducted, but respiratory distress occurred after 3 months due to tumor re-growth at the stent margin. Accordingly, stent-in-stent placement was performed and her respiratory symptoms improved. However, superior vena cava syndrome occurred 1 month later and the patient died. We consider that placing an EMS is effective in patients with tracheal stenosis due to EM that is judged to be an oncological emergency.

Abstract
Purpose Preoperative chemoradiotherapy (CRT) using 5-fluorouracil (5-FU)-based chemotherapy is the standard of care for rectal cancer. The effect of additional chemotherapy during the period between the completion of radiotherapy and surgery remains unclear. Predictive factors for CRT may differ between combination chemotherapy with S-1 and with tegafur-uracil/leucovorin (UFT/LV). Methods The subjects were 54 patients with locally advanced rectal cancer who received preoperative CRT with S-1 or UFT/LV. The pathological tumor response was assessed according to the tumor regression grade (TRG). The expression levels of 18 CRT-related genes were determined using RT-PCR assay. Results A pathological response (TRG 1-2) was observed in 23 patients (42.6%). In a multivariate logistic regression analysis for pathological response, the overall expression levels of four genes, HIF1A, MTHFD1, GGH and TYMS, were significant, and the accuracy rate of the predictive model was 83.3%. The effects of the gene expression levels of GGH on the response differed significantly according to the treatment regimen. The total pathological response rate of both high-GGH patients in the S-1 group and low-GGH patients in the UFT/LV group was 58.3%. Conclusion Additional treatment with 5-FU-based chemotherapy during the interval between radiotherapy and surgery is not beneficial in patients who have received 5-FU-based CRT. The expression levels of four genes, HIF1A, MTHFD1, GGH and TYMS, in tumor tissues can predict the response to preoperative CRT including either S-1 or UFT/LV. In particular, the gene expression level of GGH in tumor tissues may be a useful biomarker for the appropriate use of S-1 and UFT/LV in CRT.

Abstract
A 74-year-old woman undergoing outpatient follow-up for reflux esophagitis and atrophic gastritis tested positive for Helicobacter pylori and underwent primary eradication therapy with lansoprazole (LPZ) 30 mg, amoxicillin (AMPC) 750 mg, and clarithromycin (CAM) 200 mg twice daily for 1 week in August 2012. A urea breath test (UBT) after this treatment revealed that eradication had failed. Secondary eradication therapy was carried out with esomeprazole (EPZ) 20 mg, AMPC 750 mg, and metronidazole (MNZ) 250 mg twice daily for 1 week, but this also failed. The third attempt at eradication consisted of EPZ 20 mg, AMPC 750 mg, and sitafloxacin (STFX) 100 mg twice daily for 1 week, but this also ended in failure. A fourth attempt using rabeprazole (RPZ) 20 mg (4 times daily) with MNZ 250 mg and STFX 100 mg twice daily for 2 weeks also failed, as did a fifth attempt in April 2015 using vonoprazan (VPZ) 20 mg, AMPC 750 mg, and MNZ 250 mg twice daily for 1 week. Eradication was finally successful after the sixth attempt, in which the patient was treated with vonoprazan 20 mg, MNZ 250 mg, and STFX 100 mg twice daily for 2 weeks.

Abstract
The case of a patient with asymptomatic double common bile duct that was identified by chance is presented. A 41-year-old man underwent esophagogastroduodenoscopy(EGD) as part of a regular health checkup, during which he was found to have an elevated lesion in the lesser curvature of the upper gastric corpus with bile draining from its tip. Further examination led to a diagnosis of double common bile duct from the left intrahepatic bile duct to the opening into the stomach. Morphological abnormalities of the biliary tree are commonly encountered in everyday gastroenterological practice, but a double common bile duct with an ectopic opening into the stomach is comparatively rare. It is also associated with an increased risk of developing cancer of the stomach or bile duct, and as such is a biliary abnormality that must be treated with caution. This case is reported together with a discussion of the literature.

Abstract
A 16-year-old boy first presented with a pineal tumour identified by neuroimaging but without positive serum or cerebrospinal fluid markers. The tumour disappeared after 50 Gy cranial irradiation. One year later he returned with spinal epidural metastasis from the pineal germinoma and required emergency surgery. Intraoperative findings showed that the spinal tumour had originated from cerebrospinal fluid dissemination and had passed through the spinal nerve sleeve. The pathologic diagnosis of the tumour was of a pure germinoma metastasis. An epidural tumour frequently requires emergency diagnosis and treatment. Attention should be paid to the possibility of this rare but serious clinical situation caused by a metastasis from a pineal germinoma.

Abstract
1. Antagonists of the N-methyl-D-aspartate (NMDA) glutamate (Glu) receptor, including [(+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine maleate], dizocilpine maleate (MK-801), injure pyramidal neurons in the posterior cingulate/retrosplenial (PC/RS) cortex when administered systemically to adult rats and mice. 2. These results have, to our knowledge, only been reported previously in Harlan Sprague Dawley albino rats and International Cancer Research (ICR) mice, an outbred albino strain. 3. Male Non-Swiss Albino (NSA) mice, an albino outbred strain, and male C57BL/6J (B6) mice, a pigmented inbred strain, were injected systemically with 1 mg/kg of MK-801 in the first experiment. This dose of MK-801 reliably produces cytoplasmic vacuoles in neurons in layers III and IV of the PC/RS cortex in 100% of ICR mice treated 4. There was a significant difference in the number of vacuolated neurons in B6 and NSA mice, as assessed by ANOVA. The NSA were not significantly different than previously examined ICR mice, but the B6 had fewer vacuolated neurons than either of the two outbred strains. 5. In the second experiment, male NSA, ICR, and B6 mice were injected systemically with a high dose, 10 mg/kg, of MK-801. This dose has been demonstrated to result in necrosis in the same population of neurons injured by lower doses of MK-801. 6. An ANOVA indicated that there was a significant difference among the three strains of mice, and a Fisher's protected t revealed that the B6 mice were significantly different from both the NSA and ICR, but that, with our test, those two strains were indistinguishable. 7. Male ICR, NSA, and B6 mice were tested in the holeboard food search task 5 hours after 1 mg/kg of MK-801. There were significant differences between the strains in performance both pre and posttreatment. The effect of the drug was not statistically significant. 8. These results suggest that there may be a genetically mediated difference in the reaction to NMDA receptor antagonists, a finding which may be important given the NMDA receptor hypofunction hypothesis for the etiology of schizophrenic symptoms.

Abstract
The cases of nineteen patients with sternocostoclavicular hyperostosis were reviewed retrospectively. Of particular interest were the responses to antibiotics and prostaglandin inhibitors. The prostaglandin inhibitors relieved the pain within three to four weeks in sixteen of eighteen patients so treated. However, the inhibitors gradually became less effective in most patients. Oral antibiotics were more effective than the inhibitors in relieving the pain of eight of the eleven patients who were given antibiotics. Pustulosis palmaris and plantaris, commonly associated with sternocostoclavicular hyperostosis, diminished after antibiotic therapy, as did the chest pain in most patients. The similarities between the age and sex distributions and the responses to antibiotics of the patients with sternocostoclavicular hyperostosis and those with pustulosis suggest that these disorders have a common etiology, and that the pustulosis may be a so-called bacterid reaction and the hyperostosis, a manifestation of a systemic reaction to a focal infection.

Abstract
Ceftizoxime (CZX), a parenteral cephalosporin derivative belonging to the so-called third generation cephalosporin is reported to have a broad antibacterial activity, particularly against Gram-negative aerobic bacilli and some anaerobes, such as Bacteroides fragilis and a good stability to beta-lactamases. Clinical study was performed on a total of 20 cases, 9 females (1 case had urinary tract infection 3 times) and 11 males, aged from 27 to 82 years. All patients had the underlying diseases. They were bronchial asthma in 3 cases, influenza in 1, chronic pulmonary emphysema in 1, pulmonary fibrosis in 1, chronic bronchitis with strongyloidiasis in 1, lung cancer in 3, esophagus cancer in 2, stomach cancer in 1, hepatoma with urolithiasis in 1, liver cirrhosis with diabetes mellitus in 1, alcoholism with strongyloidiasis in 1, cholelithiasis in 1 and congestive heart failure in 1, respectively. Clinical diagnoses for infections were 2-acute bronchitis, 2-exacerbation of chronic bronchitis, 2-broncho-pneumonia, 2-pneumonia including one suspected case, 1-obstructive pneumonia, 2-secondary pulmonary infection, 1-pulmonary infection, 3-urinary tract infection (UTI), 1-UTI with sepsis, 1-sepsis, 1-sepsis with purulent meningitis, 1-biliary tract infection and 1-infected bronchoesophageal fistula. CZX was given by intravenous drip infusion, at a dose of 1 to 2 g, twice daily for 3 to 15 days. Because of severity in infections and underlying diseases, some cases were treated either steroid, gamma-globulin preparations or other antibiotics in combination with CZX. Twelve out of 15 cases assessed clinically responded satisfactorily to the treatment and efficacy rate was 80.0%.(ABSTRACT TRUNCATED AT 250 WORDS)
