A Case of a Rapidly Progressive Small Bowel Lymphoma with High Ki-67 Expression

Primary intestinal lymphoma is a rare disease. It accounts for approximately 1~4% of gastrointestinal malignancy. Extranodal lymphoma of the intestine mainly arises from B cells. Diffuse large B-cell lymphoma is the most common type of the disease. Approximately 40% of intestinal lymphoma can be cured, while 60% have varied disease progression. Ki-67 proliferation has been recently used as an index of cell growth to predict the progression of the disease. Reported herein is a case of a rapidly progressive small bowel diffuse large B-cell lymphoma in a 51-year-old man with a high Ki-67 expression level. He visited the emergency department because of hematochezia. Abdominal computed tomography revealed distal small bowel segmental wall thickening. He underwent operation due to spontaneous small bowel perforation. The result of the pathological examination of the resected specimen was compatible with diffuse large B-cell lymphoma. The Ki-67 index within 5 months was 90%.

Current Status and Clinical Impact of Pediatric Endoscopy in Korea / 대한소화기학회지

BACKGROUND/AIMS: In pediatrics, endoscopic examination has become a common procedure for evaluation of gastrointestinal presentations. However, there are limited data on pediatric endoscopy in Korea. The aim of this study was to analyze the current status and clinical impacts of endoscopic examination in children and adolescents. METHODS: We retrospectively reviewed the medical records of outpatients who visited the tertiary hospital. Patients under 18 years of age who underwent endoscopy were included. Endoscopic findings were classified as specific and normal based on gross findings. Specific endoscopic findings were reflux esophagitis, peptic ulcers, and Mallory-Weiss tear. Other findings included acute gastritis classified according to the updated Sydney system. RESULTS: In 722 of 330,350 patients (0.2%), endoscopic examination (554 esophagogastroduodenoscopies [EGDs], 121 colonoscopies, 47 sigmoidoscopies) was performed between January 2008 and January 2013. In EGD, abdominal pain was the most frequent presentation (64.1%). The most common diagnosis was gastritis (53.2%), followed by reflux esophagitis. The frequency of peptic ulcer disease was 12.8%. Frequent symptoms leading to colonoscopic examination were abdominal pain, diarrhea, and hematochezia. In colonoscopy, a negative result was more likely in children younger than 7 years old. After the procedure, the diagnostic yield of EGD and colonoscopy was 88.1% and 45.8%, respectively, and the rate of change in management was 67.1%. CONCLUSIONS: In pediatrics, endoscopic examination was useful for the choice of therapeutic strategy and it would be a standard method for evaluation of gastrointestinal presentation.

Clinical Characteristics of Peptic Ulcer Disease in Korea

BACKGROUND/AIMS: Clinical presentation and patterns of peptic ulcer disease (PUD) have changed because surival of people in Korea have increased. Other factors such as declining Helicobacter pylori infection rate and increased consumption of non-steroidal anti-inflammatory drugs (NSAID) including aspirin also affect the clinical patterns of PUD. The aim of this study was to evaluate the current clinical characteristics of PUD in Korea. MATERIALS AND METHODS: This study was performed from March 2011 to September 2012 in 8 institutions affiliated to the Catholic University of Korea. When the patients were diagnosed with PUD during endoscopic examination, questionnaires including life style of the patients and the endoscopic findings were obtained. The questionnaires were composed of region of residency, occupational history, blood type, clinical symptoms and signs at the presentation, alcohol history, smoking history, and consumption of drugs such as NSAID. We also analyzed the endoscopic findings of PUD including the numbers, locations, stages, and complications. RESULTS: A total 815 patients were recruited in this study. The mean age was 56.3+/-14.5 years old and 496 patients (60.9%) were men. The proportion of gastric ulcer, duodenal ulcer, and combined gastric and duodenal ulcer was 57.3%, 32.1%, and 10.6%, respectively. H. pylori infection was detected in 548 patients (67.2%) and drug-related PUD was found in 278 patients (34.1%). Complication such as bleeding, obstruction, and perforation was found in 174 patients (21.3%). CONCLUSIONS: H. pylori-related PUD is still high in Korea. Among patients with PUD, elderly patients consume much more drugs such as NSAIDs compared to younger patients.

A Case of Synchronous Occurrence of Gastric Schwannoma and Gastric Adenoma

Gastric schwannomas are rare benign tumors among the mesenchymal tumor of the gastrointestinal tract, arising from the nerve tissue which has a schwann cell sheath. These neoplasms are grossly similar to gastrointestinal stromal tumor (GIST), however, the clinical course of GIST is more aggressive compared to that of schwannomas. Synchronous occurrence of gastric epithelial and subepithelial tumors is rare. Besides, most subepithelial lesions are GIST. We present the case of a 57-year-old male with synchronous gastric schwannoma and gastric adenoma in the stomach. We found a gastric subepithelial lesion incidentally, the size of which was increasing and tubular adenoma was discovered in the covering mucosa during endoscopy follow-up. The synchronous lesion was removed by wedge resection, which was diagnosed as schwannoma with adenoma.

Colonoscopic Perforation During a Diagnostic Colonoscopy / 대한소화기내시경학회지

BACKGROUND/AIMS: Colonoscopy is a useful method for detecting colorectal disease, but complications are on the rise due to the increasing number of colonoscopies. The aim of this study was to analyze colon perforations following diagnostic colonoscopies. METHODS: We performed retrospective reviews of all patients with colonoscopic perforations between January 2000 and June 2010. RESULTS: Of 25,883 diagnostic colonoscopies performed, seven cases of colon perforations were reported. Among those, five cases had an abdominal operation history; the site of perforation was the sigmoid colon in three cases and the rectum in four cases. The manipulation type was forward viewing in three cases and retroflexion in four cases. The time to diagnosis was immediate in six cases and delayed in one case, and treatment was conservative management in three cases and surgical management in four cases. CONCLUSIONS: Special attention is required for patients with a previous abdominal operation and retroflexion. Even after perforations occur, favorable outcomes can be obtained by conservative treatment if the patient's condition is stable, the bowel preparation is proper, and there are no signs of peritonitis.

A Case of Primary Gastric Marginal Zone B-Cell Lymphoma Presenting as Multiple Polyps / 대한내과학회지

Marginal zone B-cell lymphoma of the gastrointestinal tract most commonly affects the stomach. Endoscopic findings of primary gastrointestinal lymphoma are various and heterogeneous. Lesions may appear as ulcers, erosions, or erythemas. Gastrointestinal lymphomas presenting as multiple polyps on endoscopy are rare. No case of marginal zone B-cell lymphoma manifesting as multiple polyps has been reported on the stomach, although a few cases have been reported in the colon. We present a rare case of a 77-year-old female patient diagnosed as primary gastric marginal zone B-cell lymphoma presenting as multiple polyps. She was fully treated by combination chemotherapy.

Clinical Characteristics of 17 Cases of Eosinophilic Gastroenteritis / 대한소화기학회지

BACKGROUND/AIMS: Eosinophilic gastroenteritis (EG) is a rare disease characterized by prominent eosinophilic infiltration that may involve a variable depth of one or more gastrointestinal organs. We analyzed the largest number of patients with EG among the studies carried out at a single center in Korea. METHODS: We retrospectively analyzed the clinical, laboratory, endoscopic, and radiologic features, management, and clinical outcome in 17 patients who were diagnosed as EG from January 1994 to Febuary 2008. RESULTS: Median age was 36 (2-67 years). Two of the 17 patients had a history of allergy. The most common symptoms were abdominal pain and diarrhea. Fifteen patients (88.2%) had hypereosinophilia. The ESR was moderately raised in 6 out of 14 patients. Eleven patients (64.7%) had predominant involvement of the mucosa, 1 (5.9%) of muscularis, and 5 (29.4%) of subserosa. EGD revealed non-specific findings such as erythema and edema. Abdominal Computed tomography revealed gastrointestinal wall thickenings of the involved organ, and all of 5 cases of the subserosal type had ascites. Thirteen patients (76.5%) were improved by corticosteroid treatment. Among five patients who had been followed for more than one year (12-84 months), two experienced relapse after discontinuing corticosteroids. CONCLUSIONS: EG should be considered in the differential diagnosis of unexplained gastrointestinal symptoms even in the absence of peripheral eosinophilia and in non-specific endoscopic findings.

Gastric duplication cyst associated with dorsal pancreatic agenesis and a cystic pulmonary lesion / 대한내과학회지

Gastric duplication cysts and dorsal pancreatic agenesis are rare congenital anomalies, and little is known of the association between these two anomalies. A 17-year-old woman was admitted with a cystic lung mass detected as part of a health screening program. Chest computed tomography (CT) showed a cystic lung lesion in the right lower lobe and an incidental cystic abdominal mass. She had no specific symptoms or signs. Abdominal CT and endoscopic ultrasonography (EUS) revealed a 9x7x5.5-cm cystic mass and agenesis of the body and tail of the pancreas. The cyst was removed successfully using laparoscopic gastric wedge resection. Microscopically, the muscle coat of the cyst wall was fused with the muscle layer of the stomach. Therefore, the cystic mass was diagnosed as a gastric duplication cyst. We present a patient with a pulmonary cystic lesion associated with two congenital anomalies: a gastric duplication cyst and dorsal pancreatic agenesis.

A case of HELLP syndrome accompanied by retinal detachment / 대한내과학회지

Weinstein et al. first described the HELLP (hemolytic anemia, elevated liver enzymes, and low platelets) syndrome in 1982. The incidence of HELLP syndrome is 0.2~0.6% in normal pregnant women and 4~12% in women with preeclampsia. This syndrome is accompanied by serious medical complications, including hepatic and renal failure, coagulopathy, hypertension, and pulmonary edema. Retinal detachment is an unusual, but well documented, complication of hypertensive disorder in pregnancy affecting 0.2~2% of patients with severe preeclampsia and 0.9% of patients with HELLP syndrome. This paper reports on a patient with HELLP syndrome accompanied by retinal detachment who recovered after controlling the blood pressure and receiving systemic steroids.

Idiopathic Isolated Omental Panniculitis Confirmed by Percutaneous CT-Guided Biopsy

The preoperative diagnosis of intraabdominal panniculitis is difficult due to its rarity. However, the increased use of abdominal computed tomography (CT) for a variety of indications has increased the diagnosis of intraabdominal panniculitis, including omental panniculitis. The characteristic CT features of intraabdominal panniculitis are increased attenuation of the adipose tissue, the fat-ring sign, a tumoral pseudocapsule, soft-tissue nodules, and a left-sided orientation of mass maximum transverse diameter. Recognition of these features is valuable in the diagnosis of panniculitis, and hence percutaneous CT-guided biopsy to determine their presence may prevent unwarranted surgery. We report the case of a 61-year-old man found to have an idiopathic isolated omental panniculitis that was diagnosed by abdominal CT and percutaneous CT-guided biopsy.

Relationship between Psychological Factors and Quality of Life in Subtypes of Gastroesophageal Reflux Disease

BACKGROUND/AIMS: Quality of life (QoL) is consistently decreased in gastroesophageal reflux disease (GERD), but the relationship between QoL and psychological factors in GERD has not yet been clearly defined. The present study investigated the relationship between the psychological factors of two subtypes of GERD and QoL. METHODS: A cohort of 769 participants underwent upper endoscopic evaluation in the health-promotion center of St. Paul's Hospital. The severity of GERD symptoms, psychological factors, and QoL were analyzed using the Visual Analogue Scale, the Hospital Anxiety and Depression Scale, and the abbreviated version of the World Health Organization Quality of Life instrument, respectively. RESULTS: Among the total of 769 participants, 153 participants were included in the exclusion criteria. Erosive reflux disease (ERD) and nonerosive reflux disease (NERD) were present in 106 (14%) and 61 (8%) of the participants, respectively, and 449 (58%) acted as controls. In each GERD group, the QoL had no correlatioion with the symptom severity. The scores for anxiety and depression were highest in the NERD group, and QoL scores were lower in both the ERD and NERD groups than in the control group. Anxiety and depression resulted in QoL scores being lower in both the ERD and NERD groups than in the nonanxiety and nondepressed groups, respectively. CONCLUSIONS: This study provides evidence that the QoL associated with the ERD and NERD subtypes may be more related to psychological factors than to symptom severity.

A Case of Hepatocellular Carcinoma Combined with Liver Abscess / 대한소화기학회지

Hepatocellular calcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer-related deaths worldwide. It is important to diagnose HCC exactly before management is attempted. But, the clinical presentations and radiologic findings of liver abscess, HCC, and metastatic tumor to the liver may be quite similar, and procedures such as serum tumor marker assay, computerized tomography, and ultrasonography of the liver cannot make a specific diagnosis. We report a case of HCC successfully diagnosed by surgery which was misconceived as liver abscess and not improved by medical treatment.

A Case of Advanced Gastric Cancer with Perianal Skin Metastasis / 대한소화기학회지

The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. However, skin metastases from gastric cancer are relatively rare. We herein report a case of advanced gastric cancer with perianal skin metastasis in a 70-year-old male. On admission, patient presented with epigastric pain. Endoscopy and abdominal CT scan demonstrated the stage IV gastric cancer. He had one painless nodule on perianal skin area, biopsy of that lesion showed a feature of poorly differentiated adenocarcinoma clinically from the stomach. We suspected that the perianal lesion was originated from gastric cancer.

A Case of Retrograde Jejunogastric Intussusception Diagnosed by Gastroscopy / 대한소화기내시경학회지

Retrograde intussusception of the jejunum into the stomach through the stroma of a gastroenterostomy is a very rare, but potentially fatal complication after gastrectomy. Once symptoms develop, the mortality rate is high if this is not treated within 48 hours, so making an early diagnosis with a high index of suspicion and administering prompt treatment are mandatory. Gastroscopy could be a useful diagnostic tool for patients with a history of gastrectomy and who present with abdominal pain and hematemesis, and with considering the possibility of intussusception. A 65-year-old man with a history of Billroth II gastrectomy that was done 35 years ago due to gastric ulcer perforation was admitted with abdominal pain and hematemesis. A necrotic mucosa that was suspicious of an intussuscepted small bowel tissue was detected on gastroscopy. Subsequent open reduction and small bowel resection was performed with successful results. We report here on a case of postoperative retrograde jejunogastric intussusception that occurred 35 years after Billroth II gastrectomy, and it was first diagnosed by performing gastroscopy.

A Case of Eosionophilic Gastroenteritis Involving EntireGastrointestinal Tract with Eosinophilic Ascites / 대한소화기내시경학회지

Eosinophilic gastroenteritis is a rare condition of unknown cause characterized by pheripheral eosinophilia and eosinophilic infiltration of the gastrointestinal tract. Eosonophilic gastroenteritis is generally classified according to the layer of the gastrointestinal tract that is involved. Serosal eosinophilic infiltration is the rarest form of presentation and can result in the development of eosinophilic ascites. We experienced a case of eosinophlilic gastroenteritis involving the entire gastrointestinal tract in a 34-year-old female patient with abdominal pain that was confirmed by multiple biopsies of the gastrointestinal tract with eosinophilic ascites. The patient was successfully treated with corticosteroids. We report this case with a brief review of the literature.

Retrieval of a Retained Capsule due to Isolated Crohn's Enteritis by Means of Double Balloon Enteroscopy / 대한소화기내시경학회지

Capsule endoscopy is being increasingly used for investigating GI bleeding of an obscure origin and also the bleeding that's due to Crohn's disease. Capsule endoscopy is a safe procedure with few complications. Complications of capsule endoscopy are capsule retention, incomplete small bowel examination, swallowing disorders and technical complications. However, capsule retention still remains a major concern. Crohn's disease may rarely show its first manifestation as GI bleeding. We present here a case of obscure GI bleeding in which the diagnosis of isolated Crohn's enteritis was made by using wireless CE. The retained capsule at the jejunal stricture of Crohn's disease was successfully retrieved by performing double balloon enteroscopy.

A Case of Gastrointestinal Stromal Tumor of the Jejunum with Obscure Gastrointestinal Hemorrhage Diagnosed by Exploratory Laparotomy / 대한소화기내시경학회지

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumor of the gastrointestinal tract, and they represent about 2% of all neoplasms of the gastrointestinal tract. GISTs primarily affect the stomach (50~60%), but they can also affect the small intestine (20~30%), large intestine (7%) and esophagus (1%). The clinical manifestations of GISTs vary according to the location and size of the mass. GISTs are generally KIT (CD117)-positive and are diagnosed by immunohistochemistry. Tumor size and mitotic activity are the best predictive prognostic features. The treatment of choice for primary GIST is complete surgical resection with a negative margin. A 78-year-old man who presented with melena and diffuse abdominal pain was admitted to our hospital. Esophagogastroduodenoscopy, colonoscopy, angiography and an RBC scan were performed but we were unable to locate the focus of the hemorrhage. A gastrointestinal stromal tumor (GIST) of the jejunum was diagnosed after laparotomy.
