Abstract
BACKGROUND & OBJECTIVES Genetic polymorphism of CYP2C19 is known to occur with a frequency of 12 per cent in north Indian population. But no study correlated CYP2C19 genetic polymorphism with eradication of Helicobacter pylori in north Indian gastritis patients positive for H. pylori and hence this study. METHODS Ninety one consecutive patients positive for H. pylori fulfilling the study criteria were phenotyped and genotyped for CYP2C19. They were given 20 mg omeprazole (OPZ), 750 mg amoxicillin (AMC) and 500 mg tinidazole (TNZ) (bid) for 7 days followed by 20 mg OPZ (qd) for 21 days. Non eradicated extensive metabolizers (EMs) were retreated with 40 mg OPZ (bid) and 500 mg AMC (qid) for 14 days. RESULTS EMs and poor metabolizers (PMs) excreted 4.26 +/- 0.34 (95% CI 3.59-4.92) and 0.73 +/- 0.05 (95% CI 0.63-0.82) micromol 5-OH-OPZ in 8 h, respectively. After initial therapy, EMs demonstrated 37 per cent (95% CI: 24.5-49.5) and PMs 92 per cent (95% CI: 77-107) eradication of H. pylori. Non eradicated EMs after retreatment demonstrated 90 per cent (95% CI: 79-101) eradication. INTERPRETATION & CONCLUSIONS This study demonstrated a direct correlation between CYP2C19 genetic polymorphism and H. pylori eradication in north Indian patients with gastritis. Knowing the CYP2C19 phenotype of a patient may help in prescribing optimum dose of proton pump inhibitor to achieve better therapeutic outcome.

Abstract
Epitheloid hemangioendothelioma (EHE) is a rare neoplasm of vascular origin known to arise in soft tissue, liver and lung. We describe a case of coexistent hepatic and pulmonary epitheloid hemangioendothelioma, proven on autopsy, and review the histological and radiological features of epitheloid hemangioendothelioma. The coexistence of hepatic with pulmonary EHE has been reported in only a few cases. Large confluent masses, peripheral location with capsular retraction, hypertrophy of uninvolved liver, invasion of portal and hepatic veins, enhancing margins and delayed enhancement and dense calcification are the typical features which provide a clue to diagnosis of hepatic EHE. In patients with both hepatic and pulmonary EHE it is difficult to say whether the tumor arose primarily in the lung or liver, or began simultaneously in both organs.

Abstract
UNLABELLED Accidental/suicidal ingestion of corrosive substances is common in North India. Decreased gastric secretion and delayed gastric emptying in the chronic phase of corrosive injury has been documented at our center. We hypothesize that patients in the chronic phase of corrosive injury may have delayed orocecal transit time (OCTT). OBJECTIVE To measure the orocecal transit time (using the noninvasive method of lactulose hydrogen breath test) in patients in the chronic phase of corrosive injury. METHODS Thirty patients with corrosive injury to their gastrointestinal tract with its sequelae and attending the gastroenterology services of PGIMER, Chandigarh for endoscopic dilatation of strictures were enrolled in this study. Patients with age >60 years, vagotomy, prior gastric surgery, peptic ulcer disease, systemic sclerosis, history of diabetes, hypothyroidism or intestinal pseudo-obstruction were excluded. Orocecal transit time was measured by using a 15 mL lactulose hydrogen breath test. End expiratory breath was taken every 10 min until there was a rise >10 ppm over the fasting value in two consecutive readings. RESULTS Thirty patients (11 females and 19 males) with a median age of 32 years, 27 with acid ingestion and 3 with alkali ingestion, were studied. None had symptoms of gastric outlet obstruction or gastroparesis. OCTT was significantly prolonged in the study group as compared to the control group (135.4 +/- 15.8 versus 90.6 +/- 10.4 min). No significant difference was observed between different age groups, gender, and type of caustic agent consumed. OCTT was maximally prolonged in patients with involvement of lower oesophagus, whereas patients without lower oesophagus involvement did not show significantly altered OCTT. CONCLUSION Our results show that patients with corrosive injury have prolonged OCTT even in the absence of any gastric symptoms. OCTT was prolonged maximally in patients with lower-third oesophageal cicatrization. This may a result of autovagotomy due to vagal entrapment in the cicatrization process involving the lower third of oesophagus.

Abstract
Ectopic spleen (splenoptosis) is an extremely rare condition in which the spleen is present in a nonanatomical position. Patients' symptomatology is variable and ranges from mere feeling of an abdominal lump to sudden abdominal pain due to infarction. Patient may have subacute to chronic abdominal or gastrointestinal complaints. Because of nonspecific symptoms, clinical diagnosis can be difficult; hence, imaging plays an important role. Presentation as a case of portal hypertension is extremely rare. We report a case of splenic torsion in a middle-aged woman who presented with hemetemesis from gastric varices secondary to chronic volvulus of an ectopic spleen. Preoperative diagnosis was made on the basis of ultrasonography, endoscopy, and computed tomography, which was later proved on surgery and treated successfully.

Abstract
Proton pump inhibitors (PPIs) are extensively metabolized in the liver by CYP2C19, that demonstrates genetic polymorphism with 21 mutant alleles. The subjects can be divided into 2 groups with respect to CYP2C19 phenotypes viz., extensive metabolizers (EMs) and poor metabolizers (PMs) of PPIs. This division results in marked interindividual variations in the pharmacokinetics and pharmacodynamics of PPIs in the population. Intragastric pH values and the plasma concentration of PPIs after oral ingestion were significantly lower in EMs namely normal homozygotes (CYP2C19*1/*1) and heterozygotes (CYP2C19*1/*X) compared to PMs namely mutant homozygotes (CYP2C19*X/*X) where 'X' represents the mutant allele. Hence, association has been found between the genetic polymorphism of CYP2C19 and therapeutic response to PPIs. CYP2C19 polymorphism affected eradication of Helicobacter pylori using diferent PPI based eradication therapies as PM patients demonstrated significantly higher eradication rates compared to EMs. CYP2C19 genetic polymorphism also affects the therapeutic outcome of gastroesophageal reflux disease (GERD), reflux oesophagitis and duodenal ulcers. For optimal therapeutic response with PPIs, CYP2C19 pharmacogenetics should be taken into consideration. This shall help in the prescription of optimal doses of PPIs, thus paving the way for personalized medication.

Abstract
BACKGROUND Various imaging findings of cerebral sino-venous thrombosis (CSVT) have been described on magnetic resonance venography (MRV). OBJECTIVE The purpose of this study was to evaluate the significance of visualization of the arterial system on cerebral MRV, also described as arterial contamination, as an indirect sign of CSVT. METHODS Forty patients with a clinical suspicion of venous sinus thrombosis underwent MR imaging of the brain, followed by MRV sequence, based on 2D time of flight technique in the coronal oblique plane. Patient's clinical symptoms and signs were noted with particular interest for papilloedema. Twenty-seven patients were diagnosed to have cerebral venous thrombosis on MRV, and of these, arterial contamination was visualized in 16 patients. In the remaining 13 cases, in which there was no evidence of venous sinus thrombosis, arterial contamination was absent. The sensitivity of this finding was 59.25% (n = 16/27), specificity was 100%, positive predictive value was 100% and negative predictive value was 54.2%. Of these 16 patients with arterial contamination, 12 patients had evidence of increased intracranial pressure in the form of papilloedema. CONCLUSION Visualization of the arterial system is a useful indirect sign of CSVT, and may be an indicator of increased intracranial pressure in these patients.

Abstract
Primary amebic meningoencephalitis and granulomatous amebic meningoencephalitis are central nervous system infections caused by free-living amebae. We describe the neuroimaging findings in 5 such cases on CT and MR imaging. A spectrum of findings was seen in the form of multifocal parenchymal lesions, pseudotumoral lesions, meningeal exudates, hemorrhagic infarcts, and necrosis in the brain. Familiarity with the imaging findings is important for the diagnosis and management of this nearly universally fatal disease.

Abstract
Hepatic artery pseudoaneurysm is an infrequently encountered entity that is usually seen secondary to trauma or surgical procedures. The clinical presentation is often due to complications such as massive intrahepatic or intraperitoneal bleeding as a result of rupture of the pseudoaneurysm into the biliary tree or peritoneal cavity, respectively. Hepatic artery pseudoaneurysm, associated with a liver abscess, has very rarely been described in the literature. We present the imaging features of a case of liver abscess associated with a hepatic artery pseudoaneurysm and complicated by rupture and formation of an arteriovenous fistula. The case was successfully managed by percutaneous endovascular embolization. The association between a hepatic artery pseudoaneurysm and a liver abscess must not be overlooked, bearing in mind the potentially fatal associated complications which can be averted or treated by timely intervention.

Abstract
BACKGROUND Radiologic evaluation of small bowel is usually done by barium examination, which involves considerable radiation exposure. A new sonographic method, sonoenteroclysis, is a promising technique for diagnosing small intestinal disorders. In this study the applicability, performance, and diagnostic yield of sonoenteroclysis were assessed and the results of this novel method were compared with those of barium enteroclysis. METHODS Forty-five consecutive patients with suspected small bowel disorder were studied. All patients underwent abdominal ultrasound before and after infusion of an isotonic nonabsorbable electrolyte solution containing polyethylene glycol through a nasojejunal tube (modified Billbao Dotter tube), and images at various levels were obtained. Small bowel wall thickness, luminal narrowing, intestinal dilatation, peristalsis, and extraintestinal complications were noted. It was followed by barium enteroclysis and findings were recorded. Findings of sonoenteroclysis were compared with those of barium enteroclysis. RESULTS Satisfactory distention of the intestinal lumen was obtained with sequential visualization of jejunoileal loops in 34.4 +/- 18.4 min. Of 45 patients, 10 showed normal small bowel on sonoenteroclysis and barium enteroclysis. These 10 patients served as controls. Sonoenteroclysis displayed normal diameters smaller than 3.0 and 2.0 cm for the jejunum and ileum, respectively. Bowel wall thickness was 1.7 to 3.0 mm and all five layers of bowel wall could be well appreciated. Valvulae conniventes were clearly visualized with a fold thickness between 1.4 and 2.0 mm. The remaining 35 patients showed abnormalities in the form of strictures, matted bowel loops, dilated loops, thickened folds, deformed ileocecal junction, mass lesions, etc., on sonoenteroclysis and barium enteroclysis. In addition, sonoenteroclysis showed thickened bowel wall with loss of stratification. Extraintestinal findings such as enlarged lymph nodes and ascites were also disclosed at the time of sonography. These were diagnosed subsequently as cases of tuberculosis (n = 23), celiac disease (n = 6), adenocarcinoma (n = 2), leiomyoma (n = 2), Immunoproliferative small intestinal disease (n = 1), and segmental enteritis (n = 1). CONCLUSIONS The diagnostic accuracy of sonoenteroclysis for detecting small bowel lesions is comparable to that of barium enteroclysis. This new, widely available, inexpensive, and undemanding technique can be used as an initial investigation in the evaluation of patients with small bowel disorders.

Abstract
Summary Intraductal pancreatic calculi are a rare association in patients with choledochal cyst (CC). Reported herein is a retrospective analysis of the data on pancreatic calculi in 37 patients (10 children and 27 adults) who underwent endoscopic retrograde cholangiopancreatography (ERCP) for CC over a period of 15 years. Five patients (one child and four adults) were identified as having intraductal pancreatic calculi. Three had type I and two had type IV CC. Four underwent cyst excision. No intervention was carried out for the pancreatic calculi. There was no evidence of pancreatic insufficiency on follow up and none had recurrence of abdominal pain. One patient died of cholangitis, which was the initial presenting problem. Intraductal pancreatic calculi associated with CC, although uncommon, are not rare and are not always symptomatic.

Abstract
Portal hypertensive colopathy (PHC) is a recently described entity in patients with portal hypertension which can cause even life-threatening lower gastrointestinal bleeding. In contrast to variceal bleed, there is no standardized treatment for the control of bleeding from these lesions. We report a case of alcoholic cirrhosis with portal hypertension, in whom bleeding from colonic angiodysplasia-like lesions was effectively controlled by somatostatin infusion.

Abstract
We describe the radiologic appearances of small bowel tuberculosis as shown by enteroclysis. A total of 265 patients with proven small bowel tuberculosis seen over a period of more than one decade was evaluated. All patients had positive radiologic findings as shown on enteroclysis examination. Of the 265 patients with small bowel tuberculosis, 174 had isolated small bowel involvement with a normal ileocecal region, whereas 91 had associated noncontiguous involvement of the ileocecal region. The most common radiologic finding was the presence of strictures, noted in 62.7% of cases. Most strictures were short, concentric, and smooth in outline. These strictures were solitary or multiple and located mainly in the jejunum. Other radiologic findings were adhesions (21.8%), ulcerations (9.1%), and diffuse thickening of folds (6.4%). Complications noted were in the form of enteroliths, perforations, and fistulae. The radiographic findings of small bowel tuberculosis, although non-specific, may indicate tuberculosis in a high-risk population.

Abstract
BACKGROUND Anomalous junction of the pancreaticobiliary duct (AJPB) is a rare finding in endoscopic retrograde cholangiopancreatography (ERCP). We present our data on the incidence of AJPB and associated diseases. METHODS A retrospective analysis of 2885 ERCPs performed over 15 years was done to study the incidence of AJPB and the diseases associated with this anomaly. RESULTS Of the 2885 patients who underwent ERCP, AJPB was seen in 46 (1.6%). AJPB was taken as a common channel exceeding 15 mm in length with or without dilatation of the common channel. Anomalous junction was of type I in 50%, type II in 39.1%, and type III in 2.2% cases. Y-type anomalous junction was seen in 8.7% of cases. Choledochal cyst was found in 87% of patients. Other disorders associated with AJPB were gallstones, gallbladder polyps, gallbladder carcinoma, protein plugs. and pancreatic ductal calculi. Four patients with AJPB did not show any associated abnormality. CONCLUSION AJPB is a rare finding, and the diagnosis is based on a common channel longer than 15 mm on ERCP. Choledochal cyst is the most common association with AJPB. We believe that the clinical spectrum of AJPB may unfold further with the widespread use of cholangiographic techniques.

Abstract
PURPOSE To evaluate the radiological spectrum of sequelae of corrosive acid and alkali injury to the upper gastrointestinal (GI) tract using barium contrast examination. MATERIAL AND METHODS Barium contrast radiographic films of 155 patients with a history of corrosive ingestion, acid in 120 and alkali in 35 patients with grade 2b and 3 injury on initial endoscopy, were retrospectively evaluated. Barium contrast examination of the upper GI tract was performed in the course of follow-up, beyond 3 weeks of corrosive ingestion. RESULTS The esophagus was involved in 131 patients and the stomach in 74. Fifty patients had simultaneous involvement of esophagus and stomach. Radiological findings in the esophagus were solitary or multiple strictures of varying length, intramural pseudodiverticula, and carcinoma in long-standing corrosive injury. The stomach showed cicatrization, predominantly involving the antrum, linitis plastica type deformity with multiple pseudodiverticula. There was no difference in the radiological findings as to the type of corrosive ingested. CONCLUSION Barium examination of the upper GI tract is useful in the evaluation of late sequelae of corrosive injury (acid/alkali). There was no difference in the radiological findings as to the type of corrosive ingested. Thus, contrary to general belief, we found that acid and alkali damage both the esophagus and the stomach with equal degree of severity.

Using a 21G, 1.0 cm needle catheter, transendoscopic fine needle aspiration was done under direct endoscopic vision. The aspirate confirmed the diagnosis of hepatocellular carcinoma in all of them.
