Abstract

Background: An oxyntic gland neoplasm confined to the mucosal layer (T1a) is classified as an oxyntic gland adenoma, whereas that with submucosal invasion (T1b) is defined as gastric adenocarcinoma of the fundic gland type (GA-FG). Methods: To reveal the differences in clinical features between them, we retrospectively investigated 136 patients with 150 oxyntic gland adenoma and GA-FG lesions. Results: The univariate analysis revealed that the mean size (GA-FG vs. oxyntic gland adenoma, 7.7±5.4 vs. 5.5±3.1 mm), the prevalence of elevated morphology (79.1% vs. 51.8%), black pigmentation within the lesion (23.9% vs. 9.6%), and non or closed-type atrophy (81.2% vs. 65.1%) were different between the two groups. A multivariate logistic regression analysis revealed that ≥5 mm lesion size (odds ratio, 2.96; 95% confidence interval: 1.21–7.23), elevated morphology (odds ratio, 2.40; 95% confidence interval: 1.06–5.45), and no or closed-type atrophy (odds ratio, 2.49; 95% confidence interval: 1.07–5.80) were factors in distinguishing GA-FG from oxyntic gland adenoma. When oxyntic gland neoplasms with no or one feature were judged as oxyntic gland adenomas and those with two or three features were judged as GA-FG, the sensitivity and specificity were 85.1% and 43.4% for GA-FG, respectively. Conclusions: We identified three possible distinctive features of GA-FG compared to oxyntic gland adenoma: lesion size ≥5 mm, elevated morphology, and no or closed-type atrophy.

Abstract

Objective Although Barrett's adenocarcinoma (BA) remains a minor disease in Japan, its incidence has been gradually increasing. We analyzed the characteristics of BA in Japanese populations. Methods We retrospectively reviewed medical records and analyzed the clinicopathological differences between short-segment Barrett's esophagus (SSBE) and long-segment Barrett's esophagus (LSBE), as well as metastasis. Local recurrence and metachronous lesions were analyzed only in patients who underwent endoscopic resection (ER). Patients Consecutive patients who had pathological T1 BAs resected by ER or surgery from January 2003 Results A total of 168 patients were analyzed, including 139 with SSBE and 29 with LSBE. In total, 67% of the SSBE lesions and 32% of the LSBE lesions were located between 0 and 3 o'clock (p=0.0014). No patients who achieved pathological margin-free resection (pR0) and 17% of patients who did not achieve pR0 experienced local recurrence (p=0.0131). None of the patients without lymphovascular involvement, a poorly differentiated component, lesion size of >30 mm, and submucosal invasion of >500 mu m experienced metastasis. The 5-year cumulative incidence rate of metachronous BA after ER was 0% in patients with SSBE and 40% in patients with LSBE (p=0.0005). Conclusion Superficial BA was likely to be detected at the right anterior wall of SSBE in the Japanese population. The risk for metachronous BA after ER was high in Japanese patients with LSBE, as in Western patients.

Abstract

An 86-year-old Japanese man was presented to our hospital for further investigation of duodenal adenocarcinoma. The tumor was endoscopically resected. Pathological analysis revealed coexistence of gastric foveolar metaplasia and a surrounding hyperplastic Brunner’s gland, in addition to an adenocarcinoma component. Immunostaining for MUC5AC and MUC6 confirmed the diagnosis of adenocarcinoma in situ arising from Brunner’s gland hyperplasia. This case suggests that although detailed preoperative evaluation is required to determine the depth of tumor invasion, endoscopic resection may be a promising option for the treatment of adenocarcinomas arising from Brunner’s gland hyperplasia.

Abstract

An 89-year-old woman underwent examinations for leg edema. Blood tests indicated low nutrition and low pancreatic enzymes, and a stool examination indicated fatty stool. Computed tomography showed pleural effusion, ascites, and cystic lesions in the pancreatic head and mural nodules within the cysts. Pancreatic juice cytology revealed adenocarcinoma. The diagnosis was pancreatic exocrine insufficiency caused by intraductal papillary mucinous carcinoma. The patient did not wish to undergo surgery. Therefore, diuretics, component nutrients, and pancreatic exocrine replacement therapy using pancrelipase were initiated. After starting treatment, her leg edema, pleural effusion, and ascites disappeared, and her activities of daily living improved markedly.

Abstract

A 68-year-old woman with an 11-day history of sudden abdominal pain and severe watery diarrhea was transferred to our hospital due to an exacerbation of renal function despite hydration. After treatment for dehydration and acidemia was provided in our intensive care unit, patient's renal function improved. Contrast-enhanced abdominal computed tomography was finally performed, revealing a hypervascular pancreatic mass with multiple hepatic masses. This imaging finding along with her clinical symptoms indicated watery diarrhea hypokalemia achlorhydria (WDHA) syndrome caused by a pancreatic VIPoma. Somatostatin analog was administered immediately leading to the improvement of her diarrhea and her general condition. As a result, endoscopic ultrasonography-guided fine-needle aspiration could be performed. Consequently, she was diagnosed with a pancreatic neuroendocrine tumor. She then underwent surgical resection of the pancreatic tumor and liver metastasis. As revealed in the immunohistochemical analysis of the excised tumor tissue, VIP was highly expressed, resulting in the final diagnosis of pancreatic VIPoma. Therefore, the immediate use of a somatostatin analog is crucial for improving the patient's general condition and achieving a definitive diagnosis pathologically when a patient is suspected of having a pancreatic VIPoma.

Abstract

A 21-year-old female presented at an emergency department with abdominal pain and nausea. Computed tomography (CT) of the chest and abdomen revealed a small amount of mediastinal emphysema in the precardiac area, but the underlying cause could not be identified. On admission, her plasma glucose was 371 mg/dl, glycated hemoglobin (HbA1c) was 14.0%, and blood pH was 6.91. These findings supported a diagnosis of Hamman's syndrome associated with diabetic ketoacidosis. Her diabetic ketoacidosis was managed with insulin and fluid therapy, and the mediastinal emphysema disappeared spontaneously by the time of discharge. Presence of free air of the chest and abdominal cavity must warrant a differential diagnosis of gastrointestinal perforation; however, when the free air is accompanied by diabetic ketoacidosis, it is not necessary to perform urgent endoscopy.

Abstract

We examined the re-bleeding rate after endoscopic hemostasis according to the bleeding pattern in patients with an acute lower gastrointestinal hemorrhage from colonic diverticula in 34 patients with active bleeding (Type 1) and 49 patients with exposed vessels and/or erosions in the base of diverticulum and no active bleeding (Type 2). Endoscopic hemostasis was performed by clipping the exposed vessel or erosions (direct method) or the entire diverticular orifice (reefing method). The incidence of re-bleeding was significantly higher in the Type 1 group than in the Type 2 group (p=0.002). All Type 1 cases were treated by the reefing method. In contrast, 14 of the 49 Type 2 cases were treated by the direct method, and no re-bleeding was observed in these cases. Of the other 35 Type 2 cases treated by reafing, rebleeding was seen in 5 cases. More effective endoscopic treatment is needed to prevent early re-bleeding, especially for Type 1 patients. The direct method may therefore reduce the rate of re-bleeding in Type 2 patients.

Abstract

We investigated whether emergency dynamic computed tomography (CT) is helpful to identify bleeding colonic diverticulum treatable by colonoscopy. We enrolled 95 consecutive patients given diagnoses of colonic diverticular bleeding at Hiroshima City Hospital in the present study, of whom 60 underwent CT before colonoscopy (CT group), and 35 underwent colonoscopy alone (CS group). In the CT group, bleeding diverticula were identified and treated by colonoscopy in 31 of 32 (96.9%) patients in whom extravasation was detected by CT. The interval between bleeding being recognized and CT (median 1.0 hours) in patients in whom extravasation was detected by CT was shorter than that in whom extravasation was not detected (median 5.0 hours). To identify and treat bleeding diverticula by colonoscopy, the use of emergency dynamic CT prior to colonoscopy is recommended.

Abstract

A 79-year-old man was admitted with hematemesis. Emergency upper gastrointestinal tract endoscopy revealed bleeding from the papilla of Vater. Computed tomography showed cholecystitis with a gallstone and a hematoma in the gallbladder. Angiography demonstrated a pseudoaneurysm of the anterior branch of the right hepatic artery. Emergency selective transcatheter arterial embolization (TAE) was performed, with intravascular microcoils, and complete occlusion of the pseudoaneurysm was achieved. This case shows embolization is effective in the treatment of pseudoaneurysm rupturing in the gallbladder.
