An eight-year-old, spayed female Shih-tzu, weighing 3.2 kg with a history of chronic intermittent vomiting and unknown pain for four months was referred. In ultrasonography, a small round hypoechoic mass was identified in the gastric wall. Gastric endoscopy showed a solitary raised mass with smooth surface in the pyloric antrum. Surgical resection was performed. Histopathologic findings with immunohistochemical studies showed extramedullary plasmacytoma in the gastric submucosal and muscle wall layer. The patient recovered normally without any complications. The tumor has not been re-occurred after surgical removal, to date.

Early gastric cancer (EGC) is defined as a carcinoma confined to the mucosa or submucosa of the stomach, with or without lymph-node metastasis. Synchronous liver metastasis is 5. $12.8\%$ in advanced gastric cancer, but is very low in EGC. A 64-year-old woman was admitted to St. Vincent's Hospital with a complaint of epigastric pain. Gastrofiberscopic examination showed a polypoid mass on the gastric antrum. Abdominal computed tomography demonstrated an intraluminal polypoid mass in the gastric antrum, but no tumor mass in the liver. A laparotomy revealed a solitary liver metastasis, we performed a distal partial gastrectomy with a group-2 lymph-node dissection and resection of metastatic liver tumor. Histologic examination showed a tubular adenoma with a focal carcinomatous change, Which was confined to the gastric mucosa and to the metastatic adenocarcinoma in the liver. We present a case of early gastric mucosal cancer associated with synchronous liver metastasis, along with a review of the literature.

Purpose: Owing to increased life expectancy, the number of elderly patients with gastric cancer has increased. This study aimed to identify the outcomes of gastric cancer patients aged 80 years or older through comparison of their clinicopathological characteristics, surgical outcomes, and oncologic outcomes. Materials and Methods: Between January 2006 and December 2013, the records of 478 patients who underwent surgery for gastric cancer were retrospectively evaluated. Patients were divided into two groups: patients <80 years old (n=446) and patients ${\geq}80$ years old (n=32). Results: There were no significant differences in sex, body mass index, length of hospital stay, duration of surgery, depth of invasion, nodal metastasis, histologic type, or tumor size between the two groups. However, significant differences were found for the American Society of Anesthesiologist score and the serum albumin level between the two groups. Postoperative morbidity, mortality, disease-free survival, and recurrence rate did not differ between curatively resected patients in the two groups. Conclusions: In elderly patients with gastric cancer, active treatment including radical gastrectomy is necessary.

Gastric metastasis from ovarian carcinoma is extremely rare and the prognosis for patients is poor. We report a case of multimodal treatment improving the survival time of a patient with gastric metastasis from ovarian cancer. A 73-year-old woman with known serous ovarian cancer was admitted to the hospital due to epigastric pain and dyspepsia. On esophagogastroduodenoscopy, a protruding mass was noted at the gastric antrum. She underwent distal gastrectomy with Billroth I anastomosis and lymph node dissection, including the para-aortic lymph nodes. The final pathology revealed gastric metastasis from ovarian serous adenocarcinoma. In this case, after cytoreductive surgery, chemotherapy was performed each time a recurrence was diagnosed, and remission was accomplished. She survived for 108 months after the first diagnosis of the metastatic tumor in the stomach. Multimodal treatment of metastatic lesions since the first diagnosis allowed the patient to survive longer than those in previous reports.

Surgical treatment for afferent loop syndrome (ALS) in patients with recurrent gastric cancer is usually not feasible because of the recurrent tumor mass at the anastomosis site and/or extensive carcinomatosis resulting in bowel loop fixation. Furthermore, ALS usually makes oral intake impossible, resulting in a rapid deterioration in general condition. In this situation, gastroscopic stenting at the anastomotic site and/or percutaneous external drainage may be a more feasible alternative for palliation. We herein report a recurrent gastric cancer whose ALS was successfully treated with internal and external drainage procedures.

Gastric teratoma is an extremely rare neoplasm in children which account for less than one percent of all teratomas. Unlike other teratomas, most reported gastric teratomas was benign except one case and occurred predominantly in boys. Additionally, gastric teratomas present in the first year of life as a palpable mass, abdominal distension, vomiting, hematemesis or respiratory distress. Patients with gastric teratomas have an excellent prognosis after complete excision of the tumor. We report a case of immature gastric teratoma in an one-day-old boy, which was diagnosed by abdominal sonography and CT scan, and confirmed by surgery.

A 73-year-old male visited our hospital with a complaint of general weakness. He underwent pyloric preserving pancreas-toduodenectomy due to ampullary cancer three years ago. Abdominal computed tomography scan at initial visit revealed multiple hepatic masses. A PET-CT scan showed multiple FDG uptakes at whole liver. He underwent hepatic artery infusion chemotherapy (HAIC) for five cycles. During the first cycle of HAIC, he developed gastric ulcer bleeding and endoscopic hemostasis was done successfully. Esophagogastroduodenoscopy after the 5^th cycle of HAIC revealed ulcer scar at gastric angle. PET-CT scan at 12 months showed no FDG uptake at liver, but a focal FDG uptakes at stomach and peri-gastric lymph nodes were newly developed. Esophagogastroduodenoscopy revealed about 3 cm sized mass at gastric angle. He underwent surgery and pathologic examination revealed large cell neuroendocrine carcinoma. We report a case of gastric large cell neuroendocrine carcinoma with liver metastasis treated with HAIC followed by surgery.

Purpose: This study evaluated the changes in nutritional status based on quality of life (QoL) item-level analysis to determine whether individual QoL responses might facilitate personal clinical impact. Materials and Methods: This study retrospectively evaluated QoL data obtained by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) and Quality of Life Questionnaire-Stomach (QLQ-STO22) as well as metabolic-nutritional data obtained by bioelectrical impedance analysis and blood tests. Patients were assessed preoperatively and at the 5-year follow-up. QoL was analyzed at the level of the constituent items. The patients were categorized into vulnerable and non-vulnerable QoL groups for each scale based on their responses to the QoL items and changes in the metabolic-nutritional indices were compared. Results: Multiple shortcomings in the metabolic-nutritional indices were observed in the vulnerable groups for nausea/vomiting (waist-hip ratio, degree of obesity), dyspnea (hemoglobin, iron), constipation (body fat mass, percent body fat), dysphagia (body fat mass, percent body fat), reflux (body weight, hemoglobin), dry mouth (percent body fat, waist-hip ratio), and taste (body weight, total body water, soft lean mass, body fat mass). The shortcomings in a single index were observed in the vulnerable groups for emotional functioning and pain (EORTC QLQ-C30) and for eating restrictions (EORTC QLQ-STO22). Conclusions: Long-term postoperative QoL deterioration in emotional functioning, nausea/vomiting, pain, dyspnea, constipation, dysphagia, reflux, eating restrictions, dry mouth, and taste were associated with nutritional shortcomings. QoL item-level analysis, instead of scale-level analysis, may help to facilitate personalized treatment for individual QoL respondents.

Background: Billroth I anastomosis is one of the most common reconstruction methods after distal gastrectomy for gastric cancer. Intracorporeal Billroth I (ICBI) anastomosis and extracorporeal Billroth I (ECBI) anastomosis are widely used in laparoscopic surgery. Here we compared ICBI and ECBI outcomes at a major gastric cancer center. Methods: We retrospectively analyzed data from 2,284 gastric cancer patients who underwent laparoscopic distal gastrectomy between 2009 and 2017. We divided the subjects into ECBI (n=1,681) and ICBI (n=603) groups, compared the patients' clinical characteristics and surgical and short-term outcomes, and performed risk factor analyses of postoperative complication development. Results: The ICBI group experienced shorter operation times, less blood loss, and shorter hospital stays than the ECBI group. There were no clinically significant intergroup differences in diet initiation. Changes in white blood cell counts and C-reactive protein levels were similar between groups. Grade II-IV surgical complication rates were 2.7% and 4.0% in the ECBI and ICBI groups, respectively, with no significant intergroup differences. Male sex and a body mass index (BMI) ${\geq}30$ were independent risk factors for surgical complication development. In the ECBI group, patients with a BMI ${\geq}30$ experienced a significantly higher surgical complication rate than those with a lower BMI, while no such difference was observed in the ICBI group. Conclusion: The surgical safety of ICBI was similar to that of ECBI. Although the chosen anastomotic technique was not a risk factor for surgical complications, ECBI was more vulnerable to surgical complications than ICBI in patients with a high BMI (${\geq}30$).
