Abstract
A 28-year-old female with a history of treatment for small intestinal polyps and characteristic pigmentation of her lip was clinically diagnosed with Peutz-Jeghers syndrome(PJS). Her sister had the pathogenic variant of STK11 upon genetic testing. A 20-mm polyp was identified in the second part the patient's duodenum on routine gastrointestinal surveillance, and biopsy revealed a well-differentiated adenocarcinoma. Laparoscopic partial duodenectomy with endoscopy was planned. After confirming the location of the tumor and Kocherization using a laparoscope, the polyp was resected via submucosal dissection under direct visualization with a small incision. The polyp was diagnosed as well-differentiated adenocarcinoma in situ and was resected without remnants. PJS is characterized by a high incidence of malignant tumors, and lifelong surveillance for gastrointestinal and extra-gastrointestinal tumors is necessary. The incidence of duodenal cancer is not high among patients with PJS. However, surgery for advanced cancer is highly invasive. It is desirable to detect the tumors at an early stage so that they can be resected via a less invasive treatment method such as endoscopic resection or laparoscopic surgery with an endoscope.

Abstract
Introduction Programmed cell death ligand 1 (PD-L1) expression in tumor tissues is measured as a predictor of the therapeutic efficacy of immune checkpoint inhibitors (ICIs) in many cancer types. PD-L1 expression is evaluated by immunohistochemical staining using 3,3´-diaminobenzidine (DAB) chronogenesis (IHC-DAB); however, quantitative and reproducibility issues remain. We focused on a highly sensitive quantitative immunohistochemical method using phosphor-integrated dots (PIDs), which are fluorescent nanoparticles, and evaluated PD-L1 expression between the PID method and conventional DAB method. Methods In total, 155 patients with metastatic or recurrent cancer treated with ICIs were enrolled from four university hospitals. Tumor tissue specimens collected before treatment were subjected to immunohistochemical staining with both the PID and conventional DAB methods to evaluate PD-L1 protein expression. Results PD-L1 expression assessed using the PID and DAB methods was positively correlated. We quantified PD-L1 expression using the PID method and calculated PD-L1 PID scores. The PID score was significantly higher in the responder group than in the non-responder group. Survival analysis demonstrated that PD-L1 expression evaluated using the IHC-DAB method was not associated with progression-free survival (PFS) or overall survival (OS). Yet, PFS and OS were strikingly prolonged in the high PD-L1 PID score group. Conclusion Quantification of PD-L1 expression as a PID score was more effective in predicting the treatment efficacy and prognosis of patients with cancer treated with ICIs. The quantitative evaluation of PD-L1 expression using the PID method is a novel strategy for protein detection. It is highly significant that the PID method was able to identify a group of patients with a favorable prognosis who could not be identified by the conventional DAB method.

Abstract
BACKGROUND Laparoscopic proximal gastrectomy (LPG) is an attractive option for the treatment of early gastric cancer in the upper third of the stomach. No optimal method of reconstruction after LPG has been established because of problems associated with postoperative reflux. Gastric tube reconstruction, a type of esophagogastrostomy, is a simple procedure, but it is associated with a high frequency of reflux esophagitis (RE). We investigated the relationship between RE and gastric emptying, along with nutritional parameters. SUBJECTS AND METHODS We compared gastric emptying in patients who had undergone curative LPG with gastric tube reconstruction for gastric cancer with that of patients after total gastrectomy (TG), distal gastrectomy (DG) and of healthy volunteers and patients after DG. The LPG group was divided into an RE LPG-RE (+) group and a non-reflux esophagitis (non-RE) an LPG-RE (-) group, and we compared gastric emptying and indices of nutrition, such as body weight and laboratory findings, between those among LPG-RE (+), LPG-RE (-), and TG groups. RESULTS The time lag between ingestion and peak 13 CO 2 expiration (T lag) in the healthy volunteer group was significantly shorter in the LPG group longer than those in the healthy volunteer LPG group and TG group. The T lag was significantly shorter in the RE LPG-RE (+) group than in the non-RE LPG-RE (-) group. The percentage change in body weight percentage in the non-RE LPG-RE (-) group was significantly larger than that in the RE LPG-RE (+) group at 12 months after surgery. Both the serum albumin and hemoglobin levels in the non-RE LPG-RE (-) tended to be preserved compared with those in the RE LPG-RE (+) group and TG group. CONCLUSIONS Gastric emptying was accelerated after LPG, and was associated with RE. Our data suggest that RE could be associated with body weight loss after LPG.

Abstract
Endocytoscopy (EC) facilitates real-time histological diagnosis of esophageal lesions in vivo. We developed a deep-learning artificial intelligence (AI) system for analysis of EC images and compared its diagnostic ability with that of an expert pathologist and nonexpert endoscopists. Our new AI was based on a vision transformer model (DeiT) and trained using 7983 EC images of the esophagus (2368 malignant and 5615 nonmalignant). The AI evaluated 114 randomly arranged EC pictures (33 ESCC and 81 nonmalignant lesions) from 38 consecutive cases. An expert pathologist and two nonexpert endoscopists also analyzed the same image set according to the modified type classification (adding four EC features of nonmalignant lesions to our previous classification). The area under the curve calculated from the receiver-operating characteristic curve for the AI analysis was 0.92. In per-image analysis, the overall accuracy of the AI, pathologist, and two endoscopists was 91.2%, 91.2%, 85.9%, and 83.3%, respectively. The kappa value between the pathologist and the AI, and between the two endoscopists and the AI showed moderate concordance; that between the pathologist and the two endoscopists showed poor concordance. In per-patient analysis, the overall accuracy of the AI, pathologist, and two endoscopists was 94.7%, 92.1%, 86.8%, and 89.5%, respectively. The modified type classification aided high overall diagnostic accuracy by the pathologist and nonexpert endoscopists. The diagnostic ability of the AI was equal or superior to that of the experienced pathologist. AI is expected to support endoscopists in diagnosing esophageal lesions based on EC images.

Abstract
We investigated changes in estimated glomerular filtration rate(eGFR)in 11 colorectal cancer patients(6 familial adenomatous polyposis, 5 ulcerative colitis)who underwent restorative proctocolectomy with ileal pouch-anal anastomosis(IPAA) and diverting ileostomy(DI), the tolerability and adverse events of adjuvant chemotherapy(ACT)in 4 cases. After IPAA, eGFR decreased significantly(p=0.02)and did not return to the preoperative level even after stoma closure(p<0.01). mFOLFOX6 was selected as the regimen in 4 candidates, and no significant changes in eGFR after ACT were observed. The relative dose intensity of oxaliplatin was 91.7%, and no gastrointestinal adverse events of Grade 3 or higher were observed. Although in a small number of cases, mFOLFOX6 as ACT after IPAA and DI may be feasible.

Abstract
We retrospectively analyzed clinicopathological and survival data of 8 patients with unresectable gastric cancer who underwent conversion surgery(CS)following second-line chemotherapy from April 2013 to December 2020. There were 7 males and 1 female patients with a median age of 69(64-76)years old. Five patients had 1 unresectable factor, 2 had 2 unresectable factors, and 1 had 3 unresectable factors. All patients achieved R0 resection. The median survival time(MST) of patients with CS following second-line chemotherapy was significantly longer than that without CS(73.4 vs 12.3 months, respectively). The MST of patients with CS following first-line chemotherapy was significantly longer than that without CS (22.9 vs 12.3 months, respectively). This study suggested that CS following first- or second-line chemotherapy may improve survival duration for unresectable gastric cancer.

Abstract
Esophageal neuroendocrine carcinoma is extremely rare, and its treatment strategy has not been established. We report 2 cases esophageal neuroendocrine carcinoma. Case 1: A 74-year-old man was diagnosed as having esophageal neuroendocrine carcinoma(clinical T3N4M0, Stage Ⅳa). He received 60 Gy of radiation therapy with etoposide(100 mg/m2)plus cisplatin(80 mg/m2). No recurrence has been detected 1 year after treatment. Case 2: A 78-year-old man was diagnosed as esophageal neuroendocrine carcinoma(clinical T3N0M0, Stage Ⅱ). He underwent esophagectomy with 3 field lymph nodes dissection. Adjuvant chemotherapy was administered with irinotecan(60 mg/m2)plus cisplatin(60 mg/m2). After chemotherapy, he survived 1 year without recurrence.

Abstract
BACKGROUND Gastric tube reconstruction is a form of esophagogastrostomy performed after laparoscopic proximal gastrectomy (LPG). It is a simple and safe technique, but it may cause reflux esophagitis (RE) and impair postsurgical QOL. For several years, we have developed the gastric tube reconstruction and performed it on more than 100 patients. This study aimed to determine whether gastric tube reconstruction can be a feasible choice after LPG in regard to surgical safety and postoperative nutritional status. METHODS The subjects consisted of 171 patients who underwent LPG (n = 102) or laparoscopic total gastrectomy (LTG) (n = 69). We compared the two groups in terms of surgical outcomes, incidence rate of RE, and nutritional status including postoperative weight loss and hemoglobin levels. RESULTS There were no significant differences with regard to the surgical duration and blood loss between the two groups. The incidence of RE was not significantly higher with LPG than with LTG (16.7% vs. 10.1%, respectively; P = 0.07). Later than 2 years and 6 months after surgery, the body weight percentage of preoperative body weight in the LPG group was significantly higher than that in the LTG group. Hemoglobin and ferritin levels in the LPG group were significantly higher than those in the LTG group, later than one after surgery. The overall survival rates were similar between the two groups (5-year survival rates: 97.1% vs. 94.2% in the LPG and LTG groups, respectively; P = 0.69). CONCLUSIONS Gastric tube reconstruction after LPG is simple and had better outcomes than LTG in terms of postoperative nutritional status.

Abstract
Familial adenomatous polyposis(FAP)is an autosomal dominantly inherited disorder, and the result of a germ line variant in the adenomatous poplyposis coli(APC)gene. FAP can be associated with various extracolonic lesions including thyroid cancer, which frequently occurs in women. We report the case of a 15-year-old woman diagnosed as FAP with multiple thyroid papillary carcinomas. Her mother had been treated for FAP with colorectal cancer and thyroid cancer in our department. Multiple tumors with a maximum diameter of 17 mm were detected in the right lobe of the thyroid gland during the preoperative examination. Papillary carcinoma was suspected based on fine-needle aspiration cytology. She was diagnosed with FAP because of multiple polyps on colonoscopy. We performed a subtotal thyroidectomy. Pathological findings revealed a cribriform-morular variant of papillary thyroid carcinoma. We report a rare case of papillary carcinoma of thyroid associated with FAP in a younger woman.

Abstract
BACKGROUND & AIMS Gastric dysfunction in the elderly may cause reduced food intake, frailty, and increased mortality. The pacemaker and neuromodulator cells interstitial cells of Cajal (ICC) decline with age in humans, and their loss contributes to gastric dysfunction in progeric klotho mice hypomorphic for the anti-aging Klotho protein. The mechanisms of ICC depletion remain unclear. Klotho attenuates Wnt (wingless-type MMTV integration site) signaling. Here, we examined whether unopposed Wnt signaling could underlie aging-associated ICC loss by up-regulating transformation related protein TRP53 in ICC stem cells (ICC-SC). METHODS Mice aged 1-107 weeks, klotho mice, APCΔ468 mice with overactive Wnt signaling, mouse ICC-SC, and human gastric smooth muscles were studied by RNA sequencing, reverse transcription-polymerase chain reaction, immunoblots, immunofluorescence, histochemistry, flow cytometry, and methyltetrazolium, ethynyl/bromodeoxyuridine incorporation, and ex-vivo gastric compliance assays. Cells were manipulated pharmacologically and by gene overexpression and RNA interference. RESULTS The klotho and aged mice showed similar ICC loss and impaired gastric compliance. ICC-SC decline preceded ICC depletion. Canonical Wnt signaling and TRP53 increased in gastric muscles of klotho and aged mice and middle-aged humans. Overstimulated canonical Wnt signaling increased DNA damage response and TRP53 and reduced ICC-SC self-renewal and gastric ICC. TRP53 induction persistently inhibited G1/S and G2/M cell cycle phase transitions without activating apoptosis, autophagy, cellular quiescence, or canonical markers/mediators of senescence. G1/S block reflected increased cyclin-dependent kinase inhibitor 1B and reduced cyclin D1 from reduced extracellular signal-regulated kinase activity. CONCLUSIONS Increased Wnt signaling causes age-related ICC loss by up-regulating TRP53, which induces persistent ICC-SC cell cycle arrest without up-regulating canonical senescence markers.

Abstract
The impact of colonic stenting on long-term prognosis has not yet been clarified. We compared background factors, progression-free survival, and overall survival between patients with stents(stent group)who underwent surgery after colonic stenting as a bridge to surgery and patients without stents(non-stent group)who underwent emergency surgery for left-sided colorectal cancer ileus. There was no difference between the 2 groups in the induction of adjuvant chemotherapy, but the use of oxaliplatin-base was highly introduced in the stent group(p=0.03). The 5-year DFS rates were 55.1% and 70.3%(p=0.21)and the 5-year OS rates were 90.7%and 70%(p=0.35)in the stent and non-stent groups, respectively. In the present study, colon stent placement did not affect long-term prognosis.

Abstract
Gallbladder metastasis from gastric cancer is often found accidentally during postoperative pathological examinations, and its preoperative diagnosis is very difficult. There are a few reports in diagnostic imaging, and it is well known to have a very poor prognosis. There have been 13 reports on gallbladder metastasis from gastric cancer in the Japanese literature. Among the 13 reports, 10 cases were diagnosed with gallbladder metastasis synchronously and only 1 case was diagnosed as gallbladder metastasis before surgery. One case was reported as hematogenous metastasis, and 9 cases were reported as lymphoid metastasis. In total, 7 patients died, all within the first year after surgery. We experienced a case of synchronous gallbladder metastasis from gastric cancer.

Abstract
The objective of this study was to evaluate the outcomes of selective LPLN dissection(LPLD)based on pretreatment imaging in patients with advanced low rectal cancer treated with pre-operative CRT. We reviewed 32 patients without suspected LPLN metastasis based on the MDCT or MRI results before CRT. These patients underwent total mesorectal excision (TME)without LPLD. The clinical characteristics and oncological outcomes were examined. In all cases, the per-protocol treatments were completed. Tumor recurrence occurred in 14 patients at the liver(3 cases), the lung(7 cases)and the local sites(4 cases). Of the 4 cases with pelvic recurrence, no recurrence was found in the lateral lymph node area. Under the condition that pre-operative chemoradiotherapy is to be performed for advanced lower rectal cancer with negative lateral lymph node metastasis, a lateral dissection could be omitted.

Abstract
We retrospectively reviewed 13 patients in whom endoscopic stenting for colonic stenosis due to extracolonic cancers(non- CRC group)was attempted between July 2012 and January 2018. There were 5 men and 8 women, with a median age of 69 years. Primary malignancies causing colonic stenosis were gastric cancer(n=4), cholangiocarcinoma(n=2), pancreatic cancer(n=2), lung cancer(n=2), uterine cancer(n=2), and ovarian cancer(n=1). The non-CRC group patients demonstrated a significantly lower technical success rate than those who received palliative stents for colonic stenosis for primary colorectal cancer(n=51)(69% vs 98%, p<0.01). In addition, the non-CRC group patients(n=13)also demonstrated a significantly lower technical success rate(69% vs 99%, pp<0.01)than those who received stents aiming to subsequently undergo a bridge to surgery. Nonetheless, colorectal stenting for extracolonic malignancies appears to be a minimally invasive treatment and could offer patients rapid relief. Thus, it could be an effective alternative to some palliative therapies.

Abstract
There is no established treatment for appendiceal mucinous adenocarcinoma. When this condition is complicated by pseudomyxoma peritonei(PMP), multidisciplinary treatment is often administered. A 40-year-old woman was diagnosed with right ovarian cancer for which laparotomy was performed. At the time of laparotomy, we considered the tumor to be an appendiceal carcinoma infiltrating the right ovary and performed ileocecal resection with lymph node dissection(D3)and right salpingo-oophorectomy. The pathological diagnosis was stage pT3, pN0, pM0, pStage Ⅱ mucinous adenocarcinoma of the appendix. Fourteen months later, the patient underwent abdominal total hysterectomy and left salpingo-oophorectomy because a CT scan suggested recurrence in the uterus, left fallopian tube, and ovary. Seventeen months after the second operation, despite adjuvant chemotherapy, CT revealed a peritoneal nodule in the pelvic cavity. Therefore, we administered chemotherapy comprising 5 lines for 32 months, which resulted in failure. CT showed an enlarged tumor and ascites and the patient became terminally ill. We repeatedly performed cytoreduction surgery and intraperitoneal chemotherapy, which improved her QOL. One year after discharge, abdominal CT showing an abdominal wall and intraperitoneal mass. We performed again cytoreduction surgery and intraperitoneal chemotherapy. Her postoperative course is good and she is currently an outpatient.

Abstract
We experienced a case of low-grade appendiceal mucinous neoplasm complicated by pseudomyxoma peritonei that was successfully treated with cytoreductive surgery and early postoperative intraperitoneal chemotherapy. The patient was a 26- year-old man with massive ascites and a swollen appendix on the computed tomography(CT). The appendix was a cystic mass of 5 cm in size. The entire parietal peritoneum, omentum, stomach, spleen, gall bladder, and entire colon were covered with numerous mucous nodules. Total colectomy, total gastrectomy, splenectomy, cholecystectomy, total omentectomy, parietal peritonectomy, ileostomy, and intraperitoneal irrigation were performed. The pathological diagnosis was low-grade appendiceal mucinous neoplasm. Postoperative intraperitoneal chemotherapy with cisplatin and mitomycin C was performed. A residual tumor was found on the dorsal side of the hepatoduodenal ligament 3 months postoperation on the CT. The residual tumor was successfully excised via a concomitant resection of the hepatic caudate lobe. Postoperative intraperitoneal chemotherapy was then performed. No recurrence was found at 8 months postoperation. The addition of early postoperative intraperitoneal chemotherapy improved the patient's quality of life in a short period. This could be one of the treatment options.

Abstract
PURPOSES Oral mucositis is one of the most common reasons for discontinuation of S-1 adjuvant chemotherapy after radical gastrectomy. Some studies suggest that nutritional support with amino acids may improve oral mucositis. We conducted a prospective, randomized clinical trial of patients who underwent adjuvant chemotherapy for gastric cancer to examine whether an oral elemental diet prevents chemotherapy associated oral mucositis and body weight loss. METHODS Patients were randomly assigned to a group consuming Elental® (the treatment group, n = 11) or a control diet group (n = 11). Patients in the treatment group consumed one pack of Elental® per day during adjuvant chemotherapy. The primary endpoint was the presence and grade of oral mucositis. Secondary endpoints included adherence to Elental® based on the doses recorded in a diary, changes in nutrition parameters, and frequency and severity of adverse events. RESULTS The incidence of oral mucositis was significantly lower in the treatment group (9.1%) than in the control group (27.3%). The median body weight loss in the treatment group was significantly smaller than that in the control group (P = .015). According to Kaplan-Meier estimates the treatment group was significantly associated with high cumulative S-1 continuation rates (log-rank P = .047). CONCLUSION We conclude that the amino-acid-rich elemental diet Elental® may be useful as a countermeasure for S-1 adjuvant chemotherapy-induced mucositis.

Abstract
The basic treatment for retroperitoneal liposarcoma is surgical therapy. Since the administration of trabectedin for soft tissue sarcoma has been approved, another option for soft tissue sarcoma treatment has been added. We report a case of radical resection after trabectedin therapy for initially unresectable retroperitoneal liposarcoma. A 61-year-old man was admitted to our hospital with an abdominal tumor. A tumor, about 50 cm in maximal diameter, that was not movable throughout the abdomen was observed. Computed tomography revealed a giant tumor almost occupying the entire abdomen, and he was diagnosed with retroperitoneal liposarcoma based on histopathological examination of a puncture specimen. Chemotherapy containing trabectedin was administered. At the end of 8 courses, he achieved stable disease. However, the movability improved, and surgery was performed. The procedure was tumor resection with right kidney, adrenal gland, and inferior vena cava resection. Histopathological examination revealed a mixed type of well differentiated type and dedifferentiated type. The patient is alive without recurrence 10 months after the surgery.

Abstract
BACKGROUND & AIMS Depletion of interstitial cells of Cajal (ICCs) is common in diabetic gastroparesis. However, in approximately 20% of patients with diabetes, gastric emptying (GE) is accelerated. GE also occurs faster in obese individuals, and is associated with increased blood levels of glucose in patients with type 2 diabetes. To understand the fate of ICCs in hyperinsulinemic, hyperglycemic states characterized by rapid GE, we studied mice with mutation of the leptin receptor (Leprdb/db), which in our colony had accelerated GE. We also investigated hyperglycemia-induced signaling in the ICC lineage and ICC dependence on glucose oxidative metabolism in mice with disruption of the succinate dehydrogenase complex, subunit C gene (Sdhc). METHODS Mice were given breath tests to analyze GE of solids. ICCs were studied by flow cytometry, intracellular electrophysiology, isometric contractility measurement, reverse-transcription polymerase chain reaction, immunoblot, immunohistochemistry, enzyme-linked immunosorbent assays, and metabolite assays; cells and tissues were manipulated pharmacologically and by RNA interference. Viable cell counts, proliferation, and apoptosis were determined by methyltetrazolium, Ki-67, proliferating cell nuclear antigen, bromodeoxyuridine, and caspase-Glo 3/7 assays. Sdhc was disrupted in 2 different strains of mice via cre recombinase. RESULTS In obese, hyperglycemic, hyperinsulinemic female Leprdb/db mice, GE was accelerated and gastric ICC and phasic cholinergic responses were increased. Female KitK641E/+ mice, which have genetically induced hyperplasia of ICCs, also had accelerated GE. In isolated cells of the ICC lineage and gastric organotypic cultures, hyperglycemia stimulated proliferation by mitogen-activated protein kinase 1 (MAPK1)- and MAPK3-dependent stabilization of ets variant 1-a master transcription factor for ICCs-and consequent up-regulation of v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) receptor tyrosine kinase. Opposite changes occurred in mice with disruption of Sdhc. CONCLUSIONS Hyperglycemia increases ICCs via oxidative metabolism-dependent, MAPK1- and MAPK3-mediated stabilization of ets variant 1 and increased expression of KIT, causing rapid GE. Increases in ICCs might contribute to the acceleration in GE observed in some patients with diabetes.

Abstract
Heat shock proteins (HSPs), particularly HSP70, help restore normal cellular function following damage caused by stressors. HSP expression in tumor tissues indicates cancer progression, and while the development of HSP inhibitors is progressing, these substances are not widely used to treat cancer. HIKESHI (C11orf73) does not control the intracellular movement of HSP70 at normal temperatures; however, it does regulate the function and movements of HSP70 during heat shock. In this study, we examined the intracellular movement of HSP70 during heat shock to investigate the significance of HIKESHI expression in gastric cancer (GC) and determine if HIKESHI inhibition has cytotoxic effects. We examined HIKESHI using GC cell lines and immunostaining in 207 GC tissue samples. HIKESHI expression in GC tissues was associated with the progression of lymphatic invasion. Suppressing HIKESHI using siRNA did not affect cell viability at normal temperatures. However, suppressing HIKESHI during heat shock inhibited HSP70 nuclear transport and suppressed cell viability. Our results suggest that HIKESHI is a marker of cancer progression and that the combination of HIKESHI inhibition and hyperthermia is a therapeutic tool for refractory GC.

Abstract
Heat shock protein (HSP) expression is induced by the exposure to stress, such as fever, oxidative stress, chemical exposure, and irradiation. In cancer, HSP promotes the survival of malignant cells by inhibiting the induction of apoptosis. In colorectal cancer, a loss-of-function mutation of HSP110 (HSP110ΔE9) has been identified. HSP110ΔE9 inhibits the nuclear translocation of wild-type HSP110, which is important for its chaperone activity and anti-apoptotic effects. The patients carrying HSP110ΔE9 mutation exhibit high sensitivity to anticancer agents, such as oxaliplatin and 5-fluorouracil. There is still insufficient information about HSP110 localization, the clinicopathological significance of HSP110 expression, and its association with chemotherapy resistance in gastric cancer. Here, we found that high nuclear expression of HSP110 in gastric cancer tissues is associated with cancer progression, poor prognosis, and recurrence after adjuvant chemotherapy. In vitro results showed that HSP110 suppression increases the sensitivity to 5-fluorouracil and cisplatin of human gastric cancer cell lines. Our results suggest that nuclear HSP110 may be a new drug sensitivity marker for gastric cancer and a potential molecular therapeutic target for the treatment of gastric cancer patients with acquired anticancer drug resistance.

Abstract
Endoscopic submucosal dissection (ESD) has been used to treat patients with early gastric cancer (EGC). Although several endoscopic devices have been developed to ensure easy and safe ESD, this technique still requires an experienced, highly skilled endoscopist, as it is performed through a single gastroscope, thus requiring one-handed surgical techniques. To overcome these limitations, many ESD procedures with counter-traction have been developed, such as the double scope, double channel scope, clip with line, magnetic anchor, percutaneous traction and external grasping forceps methods. We devised a double endoscopic intraluminal operation (DEILO). Two endoscopes were simultaneously inserted into the stomach. One endoscope was used to lift the lesion, and the other was used to excise the lesion. The DEILO procedure was performed on 122 cases of EGC. In this article, we report the efficacy and safety of DEILO in patients with EGC.

Abstract
BACKGROUND F-Box protein 45 (FBXO45) is reported to be associated with cancer aggressiveness. We investigated the relationship between FBXO45 and clinicopathological factors in gastric cancer (GC). MATERIALS AND METHODS We used immunohistochemistry to investigate FBXO45 expression in 104 GC samples; the prognostic value of FBXO45 was also calculated. RESULTS FBXO45 levels in GC were higher than in normal tissues. Patients with relatively low FBXO45 expression (n=58) had increased cancer progression and poorer prognosis than those with high expression (n=46). Low FBXO45 expression was an independent negative prognostic factor in patients with GC. Using the public Kaplan-Meier plotter database, we showed that survival in patients with low expression of FBXO45 in GC was shorter than that in those with high FBXO45 expression, regardless of lymph node metastasis. CONCLUSION A low FBXO45 expression level in GC tissues may be a powerful predictor of poor prognosis. FBXO45 might, therefore, be a promising candidate for a molecular targeted therapy in GC.

Abstract
BACKGROUND Nutritional interventions often fail to prevent growth failure in childhood and adolescent malnutrition and the mechanisms remain unclear. Recent studies revealed altered microbiota in malnourished children and anorexia nervosa. To facilitate mechanistic studies under physiologically relevant conditions, we established a mouse model of growth failure following chronic dietary restriction and examined microbiota in relation to age, diet, body weight, and anabolic treatment. METHODS Four-week-old female BALB/c mice (n = 12/group) were fed ad libitum (AL) or offered limited food to abolish weight gain (LF). A subset of restricted mice was treated with an insulin-like growth factor 1 (IGF1) analog. Food access was restored in a subset of untreated LF (LF-RF) and IGF1-treated LF mice (TLF-RF) on day 97. Gut microbiota were determined on days 69, 96-99 and 120 by next generation sequencing of the V3-5 region of the 16S rRNA gene. Microbiota-host factor associations were analyzed by distance-based PERMANOVA and quantified by the coefficient of determination R2 for age, diet, and normalized body weight change (Δbwt). Microbial taxa on day 120 were compared following fitting with an overdispersed Poisson regression model. The machine learning algorithm Random Forests was used to predict age based on the microbiota. RESULTS On day 120, Δbwt in AL, LF, LF-RF, and TLF-RF mice was 52 ± 3, -6 ± 1*, 40 ± 3*, and 46 ± 2 % (*, P < 0.05 versus AL). Age and diet, but not Δbwt, were associated with gut microbiota composition. Age explained a larger proportion of the microbiota variability than diet or Δbwt. Random Forests predicted chronological age based on the microbiota and indicated microbiota immaturity in the LF mice before, but not after, refeeding. However, on day 120, the microbiota community structure of LF-RF mice was significantly different from that of both AL and LF mice. IGF1 mitigated the difference from the AL group. Refed groups had a higher abundance of Bacteroidetes and Proteobacteria and a lower abundance of Firmicutes than AL mice. CONCLUSIONS Persistent growth failure can be induced by 97-day dietary restriction in young female mice and is associated with microbiota changes seen in lean mice and individuals and anorexia nervosa. IGF1 facilitates recovery of body weights and microbiota.

Abstract
BACKGROUND & AIMS In gastrointestinal muscles, v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) is predominantly expressed by interstitial cells of Cajal (ICC) and platelet-derived growth factor receptor-α (PDGFRA) polypeptide is expressed by so-called fibroblast-like cells. KIT and PDGFRA have been reported to be coexpressed in ICC precursors and gastrointestinal stromal tumors (GISTs), which originate from the ICC lineage. PDGFRA signaling has been proposed to stimulate growth of GISTs that express mutant KIT, but the effects and mechanisms of selective blockade of PDGFRA are unclear. We investigated whether inhibiting PDGFRA could reduce proliferation of GIST cells with mutant KIT via effects on the KIT-dependent transcription factor ETV1. METHODS We studied 53 gastric, small intestinal, rectal, or abdominal GISTs collected immediately after surgery or archived as fixed blocks at the Mayo Clinic and University of California, San Diego. In human GIST cells carrying imatinib-sensitive and imatinib-resistant mutations in KIT, PDGFRA was reduced by RNA interference (knockdown) or inhibited with crenolanib besylate (a selective inhibitor of PDGFRA and PDGFRB). Mouse ICC precursors were retrovirally transduced to overexpress wild-type Kit. Cell proliferation was analyzed by methyltetrazolium, 5-ethynyl-2'-deoxyuridine incorporation, and Ki-67 immunofluorescence assays; we also analyzed growth of xenograft tumors in mice. Gastric ICC and ICC precursors, and their PDGFRA(+) subsets, were analyzed by flow cytometry and immunohistochemistry in wild-type, Kit(+/copGFP), Pdgfra(+/eGFP), and NOD/ShiLtJ mice. Immunoblots were used to quantify protein expression and phosphorylation. RESULTS KIT and PDGFRA were coexpressed in 3%-5% of mouse ICC, 35%-44% of ICC precursors, and most human GIST samples and cell lines. PDGFRA knockdown or inhibition with crenolanib efficiently reduced proliferation of imatinib-sensitive and imatinib-resistant KIT(+)ETV1(+)PDGFRA(+) GIST cells (50% maximal inhibitory concentration = 5-32 nM), but not of cells lacking KIT, ETV1, or PDGFRA (50% maximal inhibitory concentration >230 nM). Crenolanib inhibited phosphorylation of PDGFRA and PDGFRB, but not KIT. However, Kit overexpression sensitized mouse ICC precursors to crenolanib. ETV1 knockdown reduced KIT expression and GIST proliferation. Crenolanib down-regulated ETV1 by inhibiting extracellular-signal-regulated kinase (ERK)-dependent stabilization of ETV1 protein and also reduced expression of KIT and PDGFRA. CONCLUSIONS In KIT-mutant GIST, inhibition of PDGFRA disrupts a KIT-ERK-ETV1-KIT signaling loop by inhibiting ERK activation. The PDGFRA inhibitor crenolanib might be used to treat patients with imatinib-resistant, KIT-mutant GIST.

Abstract
BACKGROUND Some laparoscopic gastrectomy (LG) patients are postoperatively diagnosed with locally advanced disease or lymph node metastasis. Few reports have reviewed the outcomes or validity of LG in such patients. METHODS We retrospectively compared the outcomes of LG for gastric cancer patients postoperatively diagnosed with T3 (subserosal invasion) or higher or N1 (metastasis in 1-2 regional lymph nodes), or higher disease (n = 36), with open gastrectomy (OG) for c-stage I gastric cancer patients (n = 62). RESULTS D1 plus lymph node dissection was performed in all patients in the LG group. Blood loss was significantly lower in the LG group than in the OG group (P < 0.0010). The mean postoperative hospital stay duration was significantly shorter in the LG group than in the OG group (P = 0.0016). In the LG group, lymph node metastasis occurred in 1 patient, peritoneal dissemination in 2 patients, and liver metastasis in 1 patient. The 5-year survival rate did not significantly differ between the LG and OG groups (90.00 vs. 94.52 %; P = 0.6517). CONCLUSIONS Given the similarity in long-term outcomes between the LG and OG groups, LG is an appropriate indication for gastric cancer patients postoperatively diagnosed with locally advanced disease or lymph node metastasis.

Abstract
AIM: To investigate whether 5-hydroxytryptamine (serotonin; 5-HT) is involved in mediating abnormal motor activity in dogs after cisplatin administration.
METHODS: After the dogs had been given a 2-wk recovery period, all of them were administered cisplatin, and the motor activity was recorded using strain gauge force transducers. Blood and intestinal fluid samples were collected to measure 5-HT for 24 h. To determine whether 5-HT in plasma or that in intestinal fluids is more closely related to abnormal motor activity we injected 5-HT into the bloodstream and the intestinal tract of the dogs.
RESULTS: Cisplatin given intravenously produced abnormal motor activity that lasted up to 5 h. From 3 to 4 h after cisplatin administration, normal intact dogs exhibited retropropagation of motor activity accompanied by emesis. The concentration of 5-HT in plasma reached the peak at 4 h, and that in intestinal fluids reached the peak at 3 h. In normal intact dogs with resection of the vagus nerve that were administered kytril, cisplatin given intravenously did not produce abnormal motor activity. Intestinal serotonin administration did not produce abnormal motor activity, but intravenous serotonin administration did.
CONCLUSION: After the intravenous administration of cisplatin, abnormal motor activity was produced in the involved vagus nerve and in the involved serotonergic neurons via another pathway. This study was the first to determine the relationship between 5-HT and emesis-induced motor activity.

Abstract
BACKGROUND AND OBJECTIVES This multicenter study, which was conducted in northern Kanto, Japan, aimed to assess the efficacy of imatinib mesylate against advanced or recurrent gastrointestinal stromal tumors (GIST). METHODS The clinicopathological data of 234 GIST patients who were treated at one of the 11 participating hospitals from 2001-2011 were retrospectively reviewed. Imatinib was administered as a first-line therapy in cases involving unresectable disease or postoperative recurrence (41 cases). The median follow-up period was 4.0 years. RESULTS After a median follow-up period of 4.0 years, the patients treated with imatinib (n = 41) exhibited 1-, 3-, and 5-year overall survival (OS) rates of 92.3%, 74.9%, and 53.8%, respectively. In univariate and multivariate analyses, imatinib dose reduction and achieving a complete or partial response were found to be associated with increased OS. CONCLUSIONS Long-term imatinib treatment is recommended for patients with non-progressive disease. If patients experience significant toxicities, temporary dose reduction might be useful.

Abstract
INTRODUCTION Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disease characterized by a low platelet count and normal bone marrow. Patients with ITP undergoing surgery are thought to have increased risk for postoperative complications because of their thrombocytopenia. PRESENTATION OF CASE we report the case of a 66-year-old woman with ITP who required an emergency operation for acute appendicitis associated with disseminated intravascular coagulation. Preoperative therapy consisted of platelet transfusions only, and intraoperative hemostasis was achieved. Postoperatively, high-dose intravenous immunoglobulin (IVIg) therapy led to an increased, stable, and adequate platelet count and good hemostasis. DISCUSSION The outcome of this case suggests that IVIg therapy is not always required for preoperative management of patients with. CONCLUSION IVIg therapy may be useful for postoperative management after emergency surgery.

Abstract
BACKGROUND Traditional Japanese medicine, known as Kampo medicine, consists of mixtures of several medicinal herbs widely used to treat upper gastrointestinal disorders in Japan. Rikkunshito, one of these medicines, has not been evaluated with respect to its influence on gastrointestinal motor activity. We investigated the effect of rikkunshito on upper gastrointestinal motility and plasma ghrelin concentrations in conscious dogs. METHODS Contractile response to intragastric administration of rikkunshito was studied via surgically implanted force transducers. A powdered extract of rikkunshito (1.3, 2.7, and 4.0 g) dissolved in water was administered into the stomachs of normal and vagotomized dogs before feeding and gastric emptying was evaluated. Several inhibitors of gastrointestinal motility (atropine, hexamethonium, and ondansetron) were injected intravenously before intragastric administration of rikkunshito. Plasma acylated ghrelin levels after intragastric administration of rikkunshito were measured. RESULTS In a fasting state, intragastric administration of rikkunshito induced phasic contractions in the duodenum and jejunum in normal dogs. Rikkunshito-induced contractions were inhibited by atropine, hexamethonium and ondansetron. In vagotomized dogs, rikkunshito induced phasic contractions, similar to normal dogs. Gastric emptying was accelerated by intragastric administration of rikkunshito in a dose-dependent manner. The plasma acylated ghrelin level 150 min after intragastric administration of 4.0 g of rikkunshito was significantly higher than the control value. CONCLUSIONS Intragastric administration of rikkunshito stimulates gastrointestinal contractions in the interdigestive state through cholinergic neurons and 5-HT type 3 receptors. Moreover, rikkunshito increases plasma acylated ghrelin levels. Rikkunshito may alleviate gastrointestinal disorders through its prokinetic effects.

Abstract
Abstract
Background & Aims: Most GIST harbor oncogenic KIT or PDGFRA mutations, which are in most cases heterozygous. However, most GIST co-express both wild-type KIT and PDGFRA with the mutated KIT or PDGFRA. Signaling mediated by heterodimers of the wild-type receptors contribute to GIST growth even after blocking oncogenic signaling by KIT/PDGFRA inhibitors such as imatinib. Previously we found that crenolanib (CP-868596), a PDGFRA/B tyrosine kinase inhibitor with >100-fold selectivity over other tyrosine kinases including KIT and a potent inhibitor of oncogenic PDGFRA signaling in vitro, inhibited the proliferation of KIT+PDGFRA+PDGFRB− GIST-T1 cells with a potency comparable to that of imatinib (IC50: 5.3 nM; imatinib: IC50: 3.5 nM) but had very little effect in the KITlow/−PDGFRAlow/−PDGFRB+ GIST48B cells (maximum inhibition: <50%; IC50>75 nM) and in mouse stem cells for interstitial cells of Cajal (ICC-SC), a presumed cellular source for GIST, which share a phenotype with GIST48B cells (IC50 >600 nM; Hayashi et al., Gastroenterology 2012; 142:S30). Here we investigated whether the antiproliferative effect of crenolanib was dependent on KIT expression, and studied crenolanib's effect on KIT/PDGFRA signaling and on the stability of ETV1, a transcription factor required for GIST growth and survival. Methods: Protein expression and phosphorylation were studied by Western blotting. KITlow/−PDGFRAlow/+PDGFRB+ murine ICC-SC (2xSCS2F10) were retrovirally transduced to express wild-type murine KIT. Cell proliferation was studied by methyl-tetrazolium salt assay. Results: Expression of wild-type KIT in retrovirally transduced ICC-SC dramatically reduced crenolanib's IC50 from 1157 nM to 121 nM. In GIST-T1 cells, crenolanib significantly reduced PDGFRA and KIT protein expression, inhibited PDGFRA phosphorylation (IC50: 5 nM) but had no effect on KIT phosphorylation. Crenolanib applied at 8.3 nM concentration rapidly and profoundly inhibited phosphorylation of ERK1/2 MAP kinases and reduced ETV1 protein levels by >50% in 2 h. The MEK inhibitor PD98059 (50 μM) reproduced crenolanib's effect on ETV1 protein levels with an identical time-course. The inhibitory effects of both crenolanib and PD98059 on ETV1 protein expression could be reversed with the proteasome inhibitor MG132 (10 μM) and accentuated with the protein synthesis inhibitor cycloheximide (10 μg/mL). ETV1 was undetectable in the crenolanib-resistant, KITlow/−PDGFRAlow/−PDGFRB+ GIST48B cells. Conclusions: In KIT mutant, KIT+PDGFRA+PDGFRB− GIST cells, crenolanib induced ETV1 protein degradation by suppressing PDGFRA-dependent MAPK phosphorylation. Crenolanib's antiproliferative effect in these cells may depend on KIT-induced ETV1 expression and reflect the destabilization of ETV1. Grant support: NIH DK58185.

Abstract
During fasting, gastrointestinal (GI) motility is characterized by cyclical motor contractions. These contractions have been referred to as interdigestive migrating contractions (IMCs). In dogs and humans, IMCs are known to be regulated by motilin. However, in rats and mice, IMCs are regulated by ghrelin. It is not clear how these peptides influence each other in vivo. The aim of the present study was to investigate the relationship between ghrelin and motilin in conscious dogs. Twenty healthy beagles were used in this study. Force transducers were implanted in the stomach, duodenum, and jejunum to monitor GI motility. Subsequent GI motility was recorded and quantified by calculating the motility index. In examination 1, blood samples were collected in the interdigestive state, and levels of plasma ghrelin and motilin were measured. Plasma motilin peaks were observed during every gastric phase III, and plasma ghrelin peaks occurred in nearly every early phase I. Plasma motilin and ghrelin levels increased and decreased cyclically with the interdigestive states. In examination 2, saline or canine ghrelin was administered intravenously during phase II and phase III. After injection of ghrelin, plasma motilin levels were measured. Ghrelin injection during phases II and III inhibited phase III contractions and decreased plasma motilin levels. In examination 3, ghrelin was infused in the presence of the growth hormone secretagogue receptors antagonist [d-Lys3]-GHRP-6. Continuous ghrelin infusion suppressed motilin release, an effect abrogated by the infusion of [d-Lys3]-GHRP-6. Examination 4 was performed to evaluate the plasma ghrelin response to motilin administration. Motilin infusion immediately decreased ghrelin levels. In this study, we demonstrated that motilin and ghrelin cooperatively control the function of gastric IMCs in conscious dogs. Our findings suggest that ghrelin regulates the function and release of motilin and that motilin may also regulate ghrelin.

Abstract
BACKGROUND To investigate neural regulation at the ileocecal junction (ICJ) and motility changes after ileocecal resection (ICR). Previous studies showed normal basal motility at the ICJ directly by force transducers in dogs, but these observations were limited to normal contractile activity. METHODS Continuous strain gauge recordings of stomach, terminal ileum, ileocecal sphincter (ICS), and colon were performed in dogs. The dogs were divided into four groups, namely control (CONT), extrinsic denervation at ICJ (ED), intrinsic denervation at ICJ (ID), and ICR groups. Colonic activity was recorded 2 h before a meal, in the early postprandial period (first 2 h), and in the late postprandial period (4-6 h after a meal). The meal lasted 5 min. KEY RESULTS Motility index was significantly increased at the ICS (P = 0.0056) and proximal colon (P = 0.0059) after feeding. However, such changes were not observed in the ED and ID groups. The amplitude of contractions at proximal colon in the interdigestive state was significantly decreased by ED. In the ID and ICR groups, the numbers of nonmigrating contractions were significantly decreased (P < 0.05), and colonic migrating motor complex (CMMC) ratio was significantly higher than that of the CONT group (P < 0.001). The dogs in these two groups had diarrhea. CONCLUSIONS & INFERENCES Gastrocolonic response at the ICJ may require both intrinsic and extrinsic innervation. When ID was performed, CMMC ratio increased. As a result, intraluminal water absorption may have decreased. ID may be one of the causes of diarrhea after ICR.

Abstract
BACKGROUND The aim of this study was to investigate the effects of Rikkunshito on ghrelin secretion and on cisplatin-induced anorexia in humans. METHODS The study was performed as a crossover design, and ten unresectable or relapsed gastric cancer patients were randomly divided into two groups. Group A (n = 5) was started on Rikkunshito (2.5 g three times daily, orally) from the first course of chemotherapy and followed by a second course without Rikkunshito. A treatment with reversed order was performed for Group B (n = 5). All patients received combined chemotherapy with S-1 plus cisplatin. The primary endpoint was the amount of oral intake, and the categories of scales of anorexia, nausea, and vomiting; secondary endpoints included the plasma concentration of acylated ghrelin. RESULTS In the Rikkunshito-on period, no decrease of the plasma concentration of acylated ghrelin induced by cisplatin was observed. The average oral intake in the Rikkunshito-on period was significantly larger than that in the Rikkunshito-off period, and the grade of anorexia was significantly lower in the Rikkunshito-on period than in the Rikkunshito-off period. CONCLUSION Rikkunshito appeared to prevent anorexia induced by cisplatin, resulting in effective prophylactic administration of chemotherapy with cisplatin, and patients could continue their treatments on schedule.

Abstract
BACKGROUND AND AIMS Postoperative ileus is a transient bowel dysmotility that occurs following many types of operations and is a common complication of gastrointestinal surgery. Mosapride citrate is an agonist of the 5-hydroxytryptamine 4 receptor and accelerates upper gut motility. No study has evaluated its effect on gastrointestinal motility after surgery. The aim of this study was to investigate whether mosapride citrate reduces the duration of postoperative ileus. METHODS Thirty patients with colon cancer who underwent colectomy were divided into two groups: the mosapride group and the control group. The mosapride group received mosapride 15 mg by mouth with a minimal amount of water three times a day, starting on postoperative day 1. The control group received only a minimal amount of water on the same schedule. Patients were allowed to resume oral feeding on postoperative day 4. Postoperative time to first flatus and defecation were evaluated, and the amount of food intake was observed. Gastrointestinal motility was recorded on postoperative day 8. RESULTS The appearance ratio of interdigestive migrating contractions and the motility index at the antrum and duodenum were significantly higher in the mosapride group than in the control group. The time to first flatus and defecation were significantly shorter in the mosapride group than in the control group. The amount of food intake on postoperative days 6 and 7 was significantly larger in the mosapride group than in the control group. CONCLUSION Mosapride citrate reduces the duration of postoperative ileus and may improve outcomes after gastrointestinal surgery.

Abstract
A 74-year-old man had an endoscopic type 0'-IIc tumor in the upper gastric body on the greater curvature and biopsy showed the tumor to be a well-differentiated adenocarcinoma (Group 5). He was referred to us for endoscopic submucosal dissection (ESD). Endoscopy revealed fold convergency, fold swelling, and fusion of the fold, indicating tumor invasion into the submucosa, which was outside the indications for ESD. In addition, there was an increase of serum bone-type alkaline phosphatase (ALP-III and ALP-IV) and urinary cross-linked N-terminal telopeptide of type I collagen (a bone metabolism marker), while (18)F-fluorodeoxyglucose positron emission tomography showed increased uptake in the left pelvis and Th10, suggesting bone metastases. We first diagnosed gastric cancer with bone metastases; however, the symptoms suggested pathological bone fracture and no bone pain. Therefore, a computed tomography-guided aspiration bone biopsy was performed to exclude the possibility of Paget's disease of bone. Biopsy specimens revealed no tumor and a mosaic pattern. No increased uptake of (18)F-FAMT (L-[3-(18)F] α-methyltyrosine) supported a diagnosis of no bone metastases from gastric cancer. We finally diagnosed gastric cancer accompanied by Paget's disease of bone and performed a laparoscopy-assisted proximal gastrectomy. The pathological diagnosis was U less 0-IIb, and U post 0-IIc ypT1a (M) N0H0P0M0 yp stage IA. In gastric cancer patients with suspected bone metastasis, we also need to consider Paget's disease of bone.

Abstract
BACKGROUND Postoperative ileus (POI) is one of the most common complications of gastrointestinal surgery. The present study was performed to evaluate the effects of glutamine administration on POI after gastric surgery in humans. SUBJECTS AND METHODS The subjects were 31 patients who underwent partial distal gastrectomy for gastric cancer and who were randomly assigned to one of two groups based on postoperative treatment: the glutamine group (3 g/day) and the control group. Manometric recording was done 12 days after surgery, and plasma glutamine concentrations were measured preoperatively and on postoperative day 12. RESULTS Motor activities of the duodenum in the glutamine group were significantly greater than those of the control group in the interdigestive state. The incidence of phase III motor activity (interdigestive migrating motor contractions) in the glutamine group was significantly higher than that in the control group (60 versus 19%). The glutamine group showed a significantly smaller decrease of plasma glutamine levels compared with the control group. CONCLUSIONS Glutamine could act as a motility-recovery agent after gastrectomy in humans.

Abstract
BACKGROUND Melanoma antigen-encoding gene-1 (MAGE-1), a cancer/testis antigen, has been reported to be expressed in various types of cancer. We investigated the clinicopathological features and prognostic significance of MAGE-1 expression in advanced gastric cancer (AGC). METHODS Immunohistochemical staining for MAGE-1 was performed on surgical specimens obtained from 135 patients with AGC. RESULTS Positive expression of MAGE-1 detected in cytoplasm was observed in 44 of 135 cases (32.6%) in primary tumors and 26 of 96 (27.1%) in lymph node metastases. In noncancerous gastric tissues, apparent MAGE-1 expression was not detected. MAGE-1 in primary tumor was correlated with advanced age (P < 0.001), macroscopic infiltrated type (P = 0.035), and presence of vascular invasion (P = 0.027). The 5-year cancer-specific survival rates of AGC patients with positive MAGE-1 expression were significantly lower than those of patients with negative MAGE-1 (positive: 31.6%, negative: 57.6%, P = 0.038). On multivariate analysis, MAGE-1 expression was not an independent prognostic predictor of AGC (P = 0.064). In differentiated AGC patients, MAGE-1 expression was correlated with advanced age (P = 0.003), macroscopic infiltrated type (P = 0.009), and presence of lymph node metastasis (P = 0.033). The cancer-specific survival rates of differentiated AGC patients with positive MAGE-1 were significantly lower than those of patients with negative MAGE-1 (P = 0.003). Positive MAGE-1 expression was an independent prognostic factor of differentiated AGC patients on multivariate analysis (P = 0.031). CONCLUSIONS These findings suggest that MAGE-1 protein expression can serve as a predictive marker of poor prognosis in differentiated AGC patients.

Abstract
BACKGROUND In Japan, the number of obese patients with gastric cancer is increasing. This study aimed to evaluate the advantages of laparoscopically assisted distal gastrectomy (LADG) for obese patients relative to those of conventional distal gastrectomy (DG). METHODS Between January 2004 and June 2009, a total of 197 consecutive patients with gastric carcinoma underwent curative distal gastrectomy with Billroth 1 reconstruction in the Gunma University Hospital. The patients were assigned to undergo LADG (n = 120) or DG (n = 77) according to the depth of tumor invasion and lymph node status. A body mass (BMI) of 25 kg/m(2) or higher was defined as obesity, and the amounts of blood loss, the operating time, the number of lymph nodes dissected, and the postoperative complications experienced by obese and nonobese patients were compared. RESULTS None of the patients in the LADG group required conversion to laparotomy. In the DG group, significantly fewer lymph nodes were retrieved from the obese patients (22.5 ± 3.4) than from the nonobese patients (31.9 ± 2.0; P < 0.05). However, among the obese patients, the number of lymph nodes retrieved did not differ significantly between the LADG and DG groups. In the LADG group, the obese patients had a longer operating time (206.6 ± 6.3 vs. 192.0 ± 3.1 min; P < 0.05) and a greater estimated blood loss (158.2 ± 24.7 vs. 101.9 ± 10.4 ml; P < 0.05) than the nonobese patients. The estimated blood loss correlated the surgical procedures and BMI. No significant difference in postoperative complications was noted between the obese and nonobese groups after each procedure. CONCLUSIONS Relative to DG, LADG did not affect the radicality of the procedure for the obese patients, and there is no significant difference in the operating time. The estimated blood loss was significantly less for LADG than for DG. Surgeons should elect to perform LADG for obese patients with gastric cancer.

Abstract
Monosodium l-glutamate (MSG) is a substance known to produce the umami taste. Recent studies indicate that MSG also stimulates a variety of activities in the gastrointestinal tract through its receptor in the gut, but no study has reported the activity in conscious large experimental animals. The aim of our study was to investigate whether direct intragastric MSG stimulates gut motility and to identify the mechanism in conscious dogs. Contractile response to intraluminal injection of MSG was studied in the fed and fasted states by means of chronically implanted force transducers. MSG (5, 15, 45, and 90 mM/kg) dissolved in water was injected into the stomach and duodenum in normal and vagotomized dogs. MSG solution was administered into the stomach before feeding, and gastric emptying was evaluated. Several inhibitors of gastrointestinal motility (atropine, hexamethonium, and granisetron) were injected intravenously before MSG administration to the stomach. The effect of MSG was investigated in Pavlov (vagally innervated corpus pouch), Heidenhain (vagally denervated corpus pouch), and antral pouch (vagally innervated) dogs. Upper gut motility was significantly increased by intragastric MSG but not significantly stimulated by intraduodenal MSG. Intragastric MSG (45 mM/kg) stimulated postprandial motility and accelerated gastric emptying. MSG-induced contractions were inhibited by truncal vagotomy, atropine, hexamethonium, and granisetron. Gut motility was increased by intrapouch injection of MSG in the Pavlov pouch, but it was not affected in the Heidenhain or antral pouch dogs. We conclude that intragastric MSG stimulates upper gut motility and accelerates gastric emptying. The sensory structure of MSG is present in the gastric corpus, and the signal is mediated by the vagus nerve.

Abstract
PURPOSE The mechanism for the initiation of giant migrating contractions (GMCs) associated with defecation is not well known. The aim of this study was to describe the characteristics of special propulsive contractions (SPCs), such as GMCs, during evacuation in four experimental dog models, with emphasis on denervation. MATERIALS AND METHODS Twenty healthy dogs were used in this study, and they were divided into four groups, i.e., control (underwent force transducer implantation alone), denervation (underwent transection of the descending nerve fibers along the caudal mesenteric artery (CMA)), transection (underwent transection of the rectum, which corresponds to transection of the enteric nerve fibers), and denervation-plus-transection (underwent transection of the descending nerve fibers along the CMA and transection of the rectum). Colonic contractile activities were continuously recorded on a computer. Five force transducers were implanted at the serosal surfaces of the colon (C1-R). The consistency of dog feces was checked daily. The parameters of rectal relaxation (RR), defecation characteristics, and SPCs, such as motility index (MI), duration, and frequency, were measured. RESULTS In the control and denervation groups, GMCs were observed with evacuation, and RR occurred synchronously with the initiation of GMCs. On the other hand, in the transection and denervation-plus-transection groups, strong force contractions without RR occurred only during evacuation. The MI and duration of the transection and denervation-plus-transection groups were higher than those of other groups (p < 0.05). The frequency of SPCs was the highest in the denervation-plus-transection group. CONCLUSIONS In conclusion, the continuity of enteric nerves is necessary for the occurrence of GMCs and rectal relaxation (RR).

Abstract
A laparotomy was performed on a 67-year-old woman with a provisional diagnosis of intestinal obstruction from a primary small bowel carcinoma. A pathological examination showed a mucinous adenocarcinoma of the ileum, with no regional lymph node metastases. There was no evidence of any other abnormality in the peritoneal cavity. Ten years after the operation, an abdominal computed tomography scan showed a recurrent tumor in the peritoneal cavity. Primary small bowel adenocarcinoma is rare in all malignant gastrointestinal neoplasms, and very few cases of the ileal mucinous adenocarcinoma have been reported. They are usually diagnosed at an advanced stage; as a result, they have a poor prognosis. We performed a radical operation for the ileal mucinous adenocarcinoma, and long-term survival was obtained. This case suggests that aggressive surgical treatment for an advanced stage of small bowel cancer leads to long-term survival.

Abstract
BACKGROUND/AIMS The objective of the present study was to establish an effective follow-up method to analyze the features of patients who relapsed after curative gastrectomy. METHODOLOGY At the Department of General Surgical Science, Gunma University, 44 of 321 patients who underwent curative gastrectomy for gastric cancer from 2002 to 2006 were found to relapse. The patients were divided into an early-recurrence group (n = 23; relapse within one year of gastrectomy) and a late-recurrence group (n = 21; relapse one year or more after gastrectomy). The clinicopathological features were examined. RESULTS The patients in the early-recurrence group were characterized by a high level of lymph node metastases (> or = N2), Stage IIIB, and the presence of vascular invasion (v2, v3). On a multiple logistic regression analysis, the depth of wall invasion (> or = T3), level of lymph node metastases (> or = N2), and degree of vascular invasion (v2, v3) were significantly correlated with recurrence within one year of gastrectomy. CONCLUSIONS Careful follow-up including frequent imaging diagnosis, e.g., using computed tomography (CT), is required for patients with a high risk of recurrence.

Abstract
A 74-year-old female had repeated relapses of right lower abdominal pain; a colonoscopic examination showed a submucosal tumor of the appendix. Under provisional diagnosis of appendicitis caused by a submucosal tumor, a laparoscopic operation was performed. The laparoscopic observation did not reveal the typical finding of appendicitis. The tumor was thought to be a malignant neoplasm. The ileocecal region was excised with lymph node dissection. Macroscopically, the mass was localized in the appendix and did not infiltrate to the cecum. Histologically, the marginal zone consisted of lymphoid cells, and centrocyte-like cells were observed. Immunohistochemically, the tumor cells were positive for CD20 and CD79a and negative for CD3, CD10, and cyclin D1. The histological diagnosis was mucosa-associated lymphoid tissue (MALT) lymphoma of the appendix. Colonic MALT lymphoma is rare and rarely diagnosed before surgery. Furthermore, very few cases of the appendiceal MALT lymphoma have been reported. The laparoscopy was used in the case of a patient diagnosed with appendicitis and considered the possibility of MALT lymphoma of the appendix. We then performed an ileocecal resection, which is considered radical surgery. The present case suggests that a laparoscopic observation is helpful for the appropriate diagnosis and therapy of MALT lymphoma of the appendix.
