Primary carcinoid tumor of duodenum are rare, Usually, small duodenal carcinoid tumors are often discovered endoscopically. Most of these tumors are asymptomatic, but in rare cases, jaundice, hemorrhage, duodenal obstruction, or carcinoid syndrome were apparent. Uaually, the recommended treatment is surgical or endoscopic excision of the tumor. We experienced a case of carcinoid tumor of duodenu in 53 year-old women. A 53-year-old female patient was admitted to our hospital because of epigastric discomfort and indigestion. On the gastrofiberscopic examination, 0.9 cm sized polypoid mass with central umblication was noted on the duodenall bulb. The biopsy specimen showed carcinoid cells. She was treated with endoscopic polypectomy.

Meckel's diverticulum, which is a persistence of a remnant of the omphalomesenteric duct, is the most common developmental anomaly of the gastrointestinal tract, with an incidence of about 2% in the general population. Typically, Meckel's diverticulum is a true diverticulum because it arises from the antimesenteric border of the small bowel and all layers of the intestinal wall are present. Complications of Meckel's diverticulum include bleeding, perforation, diverticulitis, intestinal obstruction, stones, intussusception, hernia, and neoplasm. Bleeding in particular is a common complication and has always been caused by an ulceration of the ileal mucosa adjacent to the acid-producing ectopic gastric mucosa in a Meckel's diverticulum. A case was recently experienced involving massive hematochezia from Meckel's diverticulum without ectopic gastric mucosa in a 27 year-old woman, and in herein reported.

Liddle's syndrome was described in 1963 by Liddle, et al., as the disease featuring a hypertension and hypokalemia but with negligible secretion of aldosterone. This syndrome, which morphologically belongs to an abnormal intrinsic tubular disorder with normal renal function, is characterized by hypokalemia, metabolic alkalosis, and hypertension due to the abnormal increase in excretion of potassium in distal tubules or collecting duct and the increase in reabsorption of sodium in distal tubules. This syndrome, which is rare disease, is observed with the low level of plasma and urinary aldosterone and suppressed plasma renin level and is known as dominant mode of inheritance with a family background. The authors paid attention to a 79-year-old man who showed a high blood pressure of 210/130mmHg as well as musle weakness, especially lower extremities due to metabolic alkalosis featuring a hypokalemia level of 2.0mEq/L when he was admitted to our hospital, Because his serum potassium were not improved with the medication of intravenous potassium supply, and his blood pressure continued to be high without the improvement of muscle weakness, we prescribed 300mg of spironolactone for two weeks. His symptom, however, was not cured. Then, instead of spironolactone, we prescribed 150mg of triamterene and a low salt diet which finally improved his symptoms. Because there has been no reported case in the Korean medical literature, we report a case of successfully treated Liddle's syndrome due to triamterene administration.

Background/Aims: There have been few multicenter studies on colonic polyps conducted by primary medical institutions. This study examined the detection rate of colonic polyps in primary health care institutions and the related factors while following the guidelines. Methods: The medical records of 14,029 patients who underwent colonoscopy between January-June 2020 at 40 primary medical institutions in Korea were analyzed. High-risk adenoma was defined as advanced adenoma, carcinoma, or ≥3 adenomas. Results: Most patients (71.2%) aged ≥50 years underwent re-colonoscopy within 5 years (51.3%) for diagnostic purposes (61.3%) in Korean primary medical institutions. The detection rates of colon polyps, adenoma, advanced adenoma, high-risk adenoma, and carcinoma was 59.9%, 38.9%, 5.9%, 11.4%, and 0.3% in all subjects and 59.8%, 37.5%, 8.5%, 12.9%, and 0.3% in average-risk patients, respectively. The incidences of adenoma in average-risk patients increased significantly with age (30s/40s/50s: 20.1%/29.4%/43% for adenoma, 4.4%/6.7%/10.3% for advanced adenoma, and 5.6%/9.5%/14.6% for high-risk adenoma; p<0.05). Before 50 years of age, high-risk adenoma was detected in 9.1% of patients in the first-time screening group, and the significant risk factors were being male and ≥40 years of age. The detection rate of high-risk adenoma in the normal index colonoscopy group within 5 years was 9.0%. The significant risk factors included older age, male sex, positive fecal occult blood test, stool form changes, and nonspecific symptoms (gas and indigestion). Conclusions More colonic adenoma studies targeting real-world clinical practice will be needed to revise the Korean guidelines for colorectal cancer screening and surveillance.
