    AIM: To elucidate the characteristics of hemorrhagic gastric/duodenal ulcers in a post-earthquake period within one medical district. METHODS: Hemorrhagic gastric/duodenal ulcers in the Iwate Prefectural Kamaishi Hospital during the 6-mo period after the Great East Japan Earthquake Disaster were reviewed retrospectively. The subjects were 27 patients who visited our hospital with a chief complaint of hematemesis or hemorrhagic stool and were diagnosed as having hemorrhagic gastric/duodenal ulcers by upper gastrointestinal endoscopy during a 6-mo period starting on March 11, 2011. This period was divided into two phases: the acute stress phase, comprising the first month after the earthquake disaster, and the chronic stress phase, from the second through the sixth month. The following items were analyzed according to these phases: age, sex, sites and number of ulcers, peptic ulcer history, status of Helicobacter pylori (H. pylori) infection, intake of non-steroidal anti-inflammatory drugs, and degree of impact of the earthquake disaster. RESULTS: In the acute stress phase from 10 d to 1 mo after the disaster, the number of patients increased rapidly, with a nearly equal male-to-female ratio, and the rate of multiple ulcers was significantly higher than in the previous year (88.9% vs 25%, P < 0.005). In the chronic stress phase starting 1 mo after the earthquake disaster, the number of patients decreased to a level similar to that of the previous year. There were more male patients during this period, and many patients tended to have a solitary ulcer. All patients with duodenal ulcers found in the acute stress phase were negative for serum H. pylori antibodies, and this was significantly different from the previous year's positive rate of 75% (P < 0.05). CONCLUSION: Severe stress caused by an earthquake disaster may have affected the characteristics of hemorrhagic gastric/duodenal ulcers. (C) 2013 Baishideng Publishing Group Co., Limited.

    We examined the pathologies, treatment characteristics, and clinical course of elderly ulcerative colitis (UC) patients. Among 222 UC patients (127 men, 95 women; average age, 34 +/- A 16 years), we selected 109 with UC diagnosed between 20 and 39 years of age (young adult group) and 23 diagnosed at a parts per thousand yen60 years of age (elderly group). Moreover, 12 patients diagnosed between 60 and 64 years of age (late-onset group) and 6 patients aged a parts per thousand yen60 years diagnosed under 50 years old (long-standing group) were also extracted for sub-analysis. The clinical characteristics and course were compared among the groups. The average age at onset was 29 +/- A 6 years in the young adult group and 66 +/- A 5 years in the elderly group. The frequency of immunomodulator or steroid use did not differ between the two groups. The comorbidity rate was 14.7 % in the young adult group and 69.6 % in the elderly group (P < .0001). Seven patients (58.3 %) in the late-onset UC group and none of the patients in the long-standing UC group were on steroid treatment. None of the patients in the long-standing UC group required hospitalization/surgery for UC exacerbation, while 3 (25.0 %) and 2 patients (16.7 %) in the late-onset group required hospitalization and surgery, respectively. The comorbidity rate was significantly higher in the elderly group. Treatments did not differ significantly between the young adult and elderly groups. Therefore, it appears that the inflammation tends to subside with age in elderly patients with long-standing UC.

    A 78-year-old man with hepatocellular carcinoma treated by chemoembolization and percutaneous ethanol injection was admitted to our hospital because of acute abdomen. The CT scan showed biliary fistula caused by hepatocellular carcinoma protruding from S3. Endoscopic retrograde cholangiopancreatography showed disruption of an intrahepatic duct and the main pancreatic duct, and contrast agent leaked into the peritoneal cavity from each duct Omental panniculitis with biliary fistula and pancreatic fistula was diagnosed. The symptoms improved by endoscopic nasobiliary drainage and endoscopic pancreatic stenting. On the 13th day after admission, we added endoscopic nasopancreatic drainage because his abdominal pain had been exacerbated by pancreatic juice leakage. Omental panniculitis by hepatocellular carcinoma complicated by biliary fistula and pancreatic fistula is extremely rare. Endoscopic transpapillary pancreaticobiliary drainage was effective for omental panniculitis in this case.

    A 75-year old man had been diagnosed at 42 years of age as having polycythemia vera and had been monitored at another hospital. Progression of anemia had been recognized at about age 70, and the patient was thus referred to our center in 2008 where secondary myelofibrosis was diagnosed based on bone marrow biopsy findings. Hematemesis due to rupture of esophageal varices occurred in January and February of 2011. The bleeding was stopped by endoscopic variceal ligation. Furthermore, in March of the same year, hematemesis recurred and the patient was transported to our center. He was in irreversible hemorrhagic shock and died. The autopsy showed severe bone marrow fibrosis with mainly argyrophilic fibers, an observation consistent with myelofibrosis. The liver weighed 1856 g the spleen 1572 g, indicating marked hepatosplenomegaly. The liver and spleen both showed extramedullary hemopoiesis. Myelofibrosis is often complicated by portal hypertension and is occasionally associated with gastrointestinal hemorrhage due to esophageal varices. A patient diagnosed as having myelofibrosis needs to be screened for esophageal/gastric varices. Myelofibrosis has a poor prognosis. Therefore, it is necessary to carefully decide the therapeutic strategy in consideration of the patient's concomitant conditions, treatment invasiveness and quality of life. (C) 2012 Baishideng.

    An intrahepatic arterioportal fistula is a rare cause of portal hypertension and variceal bleeding. We report on a patient with an intrahepatic arterioportal fistula following liver biopsy who was successfully treated by hepatectomy after unsuccessful arterial embolization. We also review the literature on symptomatic intrahepatic arterioportal fistulas after liver biopsy. A 48-year-old male with bleeding gastric varices and hepatitis B virus-associated liver cirrhosis was transferred to our hospital this patient previously underwent percutaneous liver biopsies 3 and 6 years ago. Abdominal examination revealed a bruit over the liver, tenderness in the right upper quadrant, and splenomegaly. Ultrasonographic examination, computed tomography, and angiography confirmed an arterioportal fistula between the right hepatic artery and the right portal vein with portal hypertension. After admission, the patient suffered a large hematemesis and developed shock. He was treated with emergency transarterial embolization using microcoils. Since some collateral vessels bypassed the obstructive coils and still fed the fistulous area, embolization was performed again. Despite the second embolization, the collateral vessels could not be completely controlled. Radical treatment involving resection of his right hepatic lobe was performed. For nearly 6 years postoperatively, this patient has had no further episodes of variceal bleeding. © Springer 2012.

    症例は44歳男性。2日間断続的に続く下血を主訴に来院した。緊急下部消化管内視鏡検査を施行したところ,大腸全体に血液がみられたが,出血部位の同定が困難であった。しかし,繰り返し洗浄し観察したところ,虫垂口から間欠的に血液が流出する所見がみられ,虫垂内腔からの出血であると判断した。緊急虫垂切除術を施行した。摘出標本では虫垂先端に血腫が存在していたが,病理組織学的には血腫の原因となる明らかな腫瘍性病変,血管異常などは認めなかった。下部消化管出血の原因部位として虫垂が占める割合は小さいが,可能性として考慮する必要がある。また,内視鏡的に出血部位を同定するのは困難ではあるが,正確な診断をするためには,根気よく洗浄・観察を続けることが必要であり,虫垂出血と診断した場合にはすみやかに外科的治療に移行する必要があると考える。

    In this study, we attempted to clarify the rate of recurrence of ischemic colitis (IC) and the clinical features of recurrent IC. Sixty-five patients diagnosed with IC at Omiya Medical Center, Jichi Medical School, from November 1991 to October 2001 were retrospectively reviewed. We sent the patients a questionnaire to ascertain whether they had experienced recurrences in their IC in the years following their treatment at our institution. We reviewed data on 58 patients who replied to the questionnaire.<BR>Ten (17.2%) of the 58 IC patients who replied to the questionnaire had experienced recurrence. The mean age of patients with recurrence was 49.2 years, and that of patients without recurrence was 62.1 years. Eight (88.9%) of 9 patients in the recurrence group and 17 (45.9%) of the 37 patients in the non-recurrence group had experienced constipation.<BR>Many of the patients in the recurrence group were without basic disorders. Furthermore, the recurrences were recognized at almost the same location. All lesions in the recurrence group were the transient type.<BR>In this retrospective study, patients with recurrent IC were younger than patients without it (p<0.05) and tended to experience constipation (p<0.05).

    チューブステント(TS)を用いた内視鏡的胆管ステント挿入術(EBD)を行った70例につき,ステントの開存期間に影響を与えると思われる因子について,特に糖尿病の有無について検討した,また,金属ステント(EMS)についても糖尿病の有無がステント開存期間に影響を及ぼすかどうかを検討した.<BR>単変量解析では疾患の違い,糖尿病の有無でステント開存期間に有意差を認めた.多変量解析では糖尿病の有無で有意差を認め,特に細径TSによるドレナージの際,糖尿病の有無について留意することが必要であると考えられた.EMSについては糖尿病の有無で開存期間に有意差はなく,糖尿病患者で悪性胆道閉塞の内瘻化には,EMSを選択するのが望ましいと考える.

    総胆管結石の73 歳, 男性. 脳梗塞後遺症, 腹部大動脈瘤術後で, EST後の完全切石が困難なため, 7Frピッグテール型チューブステントを胆管内に留置した. 検査終了3時間後より,急性膵炎を発症.腹部単純X線でステント十二指腸端が十二指腸水平脚に移動していた.ERCP施行時,ステント中央部側面が乳頭を圧迫しており,膵管口を閉塞したものと考えた.ステント交換により症状の改善がみられた.乳頭圧迫の原因としては,ステントが過長であったため腸蠕動によりステント先端が移動したことが考えられた.チューブステントによる比較的稀な合併症であると考えられたので,考察を加えて報告した.

    A-39-year-old man was admitted to our hospital because of a markedly decreased level of serum cholinesterase found incidentally by a blood test. Detailed examination did not reveal severe liver disease, malignant tumor, infection or organophosphate compound poisoning. Investigation of three generations of his family revealed two homozygous and five heterozygous family members with the cholinesterase deficiency gene E1s indicating familial serum cholinesterase deficiency.
