Role of Colonoscopy in Patients with Hematochezia / 대한소화기학회지

BACKGROUND/AIMS: Although colonoscopy is not indicated in patients with hematochezia, many surgeons, internists, and physicians are recommending colonoscopy for these patients in Korea. The aim of this study is to evaluate the diagnostic value of colonoscopy for patients with hematochezia. METHODS: We retrospectively reviewed the data of colonoscopy between January 2010 and December 2010. A total of 321 patients among 3,038 colonoscopies (10.6%) underwent colonoscopy to evaluate the cause of hematochezia. The patients with previous colorectal surgery (2) or polypectomy (5) were excluded. We analyzed endoscopic diagnoses. Advanced neoplastic polyps were defined as adenomas with villous histology or high grade dysplasia, or adenomas more than 10 mm in diameter. RESULTS: Hemorrhoid was the most common diagnosis (217 cases, 67.6%). Polyps were detected in 93 patients (29.0%), but advanced neoplastic polyps were found in only 14 cases (4.4%). Colorectal cancers were diagnosed in 18 patients (5.6%) including 14 rectal cancers. There was no cancer located above sigmoid-descending junction. Diverticuli were detected in 41 patients (12.8%) but there was only one case of suspected diverticular bleeding. Colitis was diagnosed in 24 patients (7.5%). Other lesions included acute anal fissure, rectal tumor, stercoral ulcer, and radiation proctitis. CONCLUSIONS: The colonoscopy had little value in patients with hematochezia because the most pathologic lesions were located below sigmoid colon. The first choice of diagnosis in patients with hematochezia is sigmoidoscopy.

Successful Treatment of an Esophagopericaridal Fistula with Pyopericardium That Developed after Laparoscopic Total Gastrectomy for Gastric Cancer by Intraoperative Stent Insertion

Esophagopericardial fistula (EPF) is a rare and serious medical condition induced by benign and malignant causes. Surgery is the main stay of treatment for benign EPF. However, there have been few reports of benign EPF treated by endoscopic stent insertion. We performed a laparoscopic total gastrectomy for treatment of a gastric cancer located at the cardia in a 62-year-old patient. A benign EPF occurred as a postoperative complication 14 days after surgery. We successfully managed the EPF through emergent laparoscopic pericardial window formation and insertion of a fully covered self-expendable metal stent during operation. The patient is being followed up without complications in the outpatient department after stent removal.

The Antisecretory Therapy Improves Anxiety and Depression Symptoms in Patients with Symptomatic Gastroesophageal Reflux Disease

BACKGROUND/AIMS: Anxiety and depression are associated with reflux symptoms in patients with gastroesophageal reflux disease (GERD). The purpose of this study is to investigate whether the anxiety and depression in patients with GERD will improve with anti-secretory treatment. MATERIALS AND METHODS: Participants who had taken upper endoscopic evaluation and who had symptoms of heartburn or acid regurgitation more than once a week were included through questionnaires. The hospital anxiety and depression scale was used to compare the scores before and after anti-secretory drug (proton pump inhibitor [PPI] or histamine-2 receptor blocker [H2 blocker]) treatment for four weeks. RESULTS: Eighty-four out of a total 94 patients were randomly assigned to a four week treatment, in which, 46 and 38 patients were each assigned to PPI and H2 blocker, respectively. Regardless of the type of treatment, anxiety scores decreased significantly from 5.8+/-3.8 to 5.2+/-3.9 after treatment (P=0.033). Depression scores of 6.3+/-3.4 before treatment reduced to 5.5+/-3.4 after treatment (P=0.011). Anxiety scores and depression scores decreased significantly after treatment in the H2 blocker group. In the response group, anxiety and depression showed significant improvement (P=0.008, P=0.011). CONCLUSIONS: Regardless of the type of drugs, anti-secretory therapy is helpful in treating symptomatic GERD patients, not only in relieving symptoms, but also in relieving anxiety and depression accompanied with GERD.

Clinical usefulness of kidney biopsy in liver transplant recipients with renal impairment

BACKGROUND: Chronic kidney disease is a common complication after liver transplantation. In this study, we analyzed the results of kidney biopsy in liver transplantation recipients with renal impairment. METHODS: Between 1999 and 2012, 544 liver transplants were performed at our hospital. We retrospectively analyzed the clinical and histological data of 10 liver transplantation recipients referred for kidney biopsy. RESULTS: The biopsies were performed at a median of 24.5 months (range, 3-73 months) after liver transplantation. The serum creatinine level was 1.81+/-0.5mg/dL at the time of kidney biopsy. There were no immediate complications. The most common diagnosis was glomerulonephritis (GN), such as immunoglobulin A nephropathy (n=4), mesangial proliferative GN(n=1), focal proliferative GN (n=1), and membranous GN (n=1). Typical calcineurin inhibitor (CNI)-induced nephrotoxicity was detected in three cases (30%).Chronic tissue changes such as glomerulosclerosis, interstitial fibrosis, and tubular atrophy were present in 90%, 80%,and 80% of cases, respectively, and mesangial proliferation was detected in 40%of cases. We began treatment for renal impairment based on the result of kidney biopsy; for example, angiotensin-receptor blockers or steroids were prescribed for GN, and the CNI dose was reduced for CNI nephrotoxicity. As a result, eight of 10 patients showed improvement in glomerular filtration rate, but two progressed to end-stage renal disease. CONCLUSION: Kidney biopsy is a safe and effective method for determining the cause of renal impairment after liver transplantation. Management of patients based on the result of kidney biopsy may improve renal outcomes.

Autosomal Dominant Polycystic Kidney Disease with an Asymptomatic Type I Choledochal Cyst / 대한내과학회지

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited renal disease. Polycystic liver disease is commonly observed in ADPKD but rarely has it been associated with a choledochal cyst. We report a case of a choledochal cyst with ADPKD in a 60-year-old female patient with ADPKD and concomitant chronic renal failure who was admitted because of acute deterioration of kidney function due to poor oral intake. There was no history of a biliary disorder and her kidney function recovered promptly after fluid replacement. Non-enhanced computed tomography was performed to evaluate ADPKD and revealed numerous cysts in both kidneys and liver. It also showed fusiform dilatation of the extrahepatic bile ducts, a finding indicative of a choledochal cyst. Liver function was within the normal range and there was no evidence of extrahepatic biliary obstruction. Magnetic resonance cholangiopancreatography confirmed the diagnosis of a type I choledochal cyst combined with ADPKD.
