Abstract PDF PubReader ePub: Accurate prediction of Helicobacter pylori infection status based on endoscopic findings is essential for optimizing management. This review emphasizes the importance of accurate endoscopic diagnosis of H. pylori infection. The endoscopic findings categorized in the Kyoto classification provide valuable indicators of infection status. Specifically, findings such as atrophic gastritis, intestinal metaplasia, nodular gastritis, enlarged folds, sticky mucus, xanthoma, and map-like redness are associated with H. pylori infection. Regular arrangement of collecting venules and linear red streaks are reliable indicators of non-infection. Selective testing based on endoscopic findings can optimize diagnosis and treatment of H. pylori infection and, minimizing unnecessary procedures. However, some findings overlap and do not clearly distinguish between current and past infections, indicating a need for further research.

Background
By analyzing small bowel capsule endoscopy (SBCE) performed in two large hospitals in Kazakhstan, we aimed to explore the characteristics of patients representative of Central Asia and the technical characteristics of SBCE.
Methods
SBCE cases were retrospectively analyzed. A descriptive analysis was conducted on the patients’ demographic data, diagnosis, and clinical symptoms. The results of SBCE, such as the lesions found, transit time and retention rate in the stomach and small bowel, and bowel visualization quality, were analyzed. Complications related to SBCE were investigated.
Results
SBCE was performed in 123 patients. Abdominal pain (81.3%) and chronic diarrhea (66.7%) were the most common symptoms, followed by weight loss (25.2%) and gastrointestinal bleeding (15.4%). The most common disease was Crohn’s disease (52.0%). Definite lesions, such as ulcers, polyps, and bleeding, were identified in 55.3% of patients. SBCE was successfully completed in all cases except for 11 (9.1%). The average small bowel transit time was 4 hours and 28 minutes. Excellent visualization (>75% of mucosa) was reported in 82.5% of patients. No patients experienced complications.
Conclusions
SBCE performed in Kazakhstan showed a high diagnostic yield with high-quality patient selection and no complications.

Objectives

: Since endoscopic findings of primary gastric lymphoma are ambiguous and diverse, it is not easy to distinguish them from gastric adenocarcinoma or secondary gastric lymphoma. The aim of this study was to investigate the difference in clinical and endoscopic features between primary gastric lymphoma and gastric involvement of lymphoma.

Methods

: Forty-eight patients were enrolled in this retrospective study between June 2008 and February 2017. The patients were divided into primary gastric lymphoma group (primary group, n = 18) and gastric involvement group (secondary group, n = 30) based on whether or not they carried gastric lesions alone. Patients’ clinical characteristics, endoscopic findings and pathologic data were retrospectively reviewed based on electronic medical records.

Results

: The mean age of patients was 63.3 ± 13.1 years and 29 patients were female (60.4%). Diffuse large B-cell lymphoma pathology (81.3%), gastric body involvement (47.9%) and ulceroinfiltrative morphology on endoscopy (43.8%) were common features. Regardless of the two groups, the initial endoscopic diagnosis was considered as lymphoma only in 41.7%. Compared with the primary group, fundus (P = 0.035) and regional lymph node (P < 0.001) were significantly associated with the secondary group. However, there was no significant difference in endoscopic findings including location, size, number, and morphology of lesion.

Conclusions

: Endoscopic diagnosis of gastric lymphoma is a challenge. There is no difference in endoscopic findings between the primary and secondary groups even when confirmed separately. However, when the lesion is present in the fundus, we keep in mind the possibility of secondary gastric lymphoma.

Abstract PDF PubReader ePub: Abstract
Brunner's gland adenoma is a rare benign small bowel neoplasm and it represents 10% of small bowel benign tumor. Most of adenoma manifest as polypoidal, multiple and size does not exceed 1 cm and mostly asymptomatic, but the lesion larger than 1 ㎝ is solitary and can cause bleeding, obstruction, intussusception and there are some reports of showing malignant transformation. Until the present, there are two cases of over 8㎝ huge Brunner's gland adenoma in Korea and each of their chief complaint was abdominal discomfort and melena, but there is no case report of over 8 ㎝ Brunner's gland adenoma accompanied with acute bleeding as seen in this case. We diagnosed an 8 ㎝ sized, huge duodenal Brunner's gland adenoma which accompanied with acute bleeding and treated it by endoscopic resection using an IT-knife, successfully.

Henoch-Schönlein purpura (HSP) is the most common form of systemic vasculitis in children. Palpable purpura, arthralgia, arthritis, abdominal pain and renal involvement are the major clinical manifestations. Gastrointestinal involvement is related with abdominal pain and bleeding.

We described a 71 year-old female experienced acute exacerbation of HSP presented with gastrointestinal bleeding. She was hospitalized for hematemesis and diagnosed duodenitis by esophagogastroduonenoscopy (EGD). Duodenitis was improved at EGD checked in 7 days. She still complained of melena and abdominal pain. There were no abnormal findings at sigmoidoscopy. Jejunal ulcer and purpura were diagnosed by capsule endoscopy. Symptoms were relieved after administration of systemic steroid. But she needed renal replacement therapy for 3 months.

Small bowel ulcer diagnosed by capsule endoscopy in patients with HSP was rarely described in Korean literature. This case suggests that capsule endoscopy have a role in diagnosis of small bowel ulcer and its severity in HSP with gastrointestinal symptom.
