Mubarik Naqash, Assistant Professor, Department of Internal Medicine SKIMS Medical College-Hospital, Bemina, Srinagar (J&K-India) Abstract The Study was carried out in a teaching cum referral Medical College Hospital of Kashmir to ascertain the diagnostic yield of upper gastrointestinal (UGI) endoscopy and ultrasonography (USG) in detecting various causes of dyspepsia in Kashmiri population. Two hundred patients, presenting with the symptoms related to dyspepsia were included in the study and were subjected to UGI endoscopy and USG. Functional dyspepsia (Normal UGI endoscopy and USG) was found in 108 (5%) in and organic dyspepsia in 92 (6%) of patients. In the organic dyspepsia group inflammatory lesions (including gastritis, gastroduodenitis, duodenitis and esophagitis) was observed in 36 (39.13%) patients while as duodenal ulcer (including channel ulcers in 3 (36.5%), cholelithiasis in 10 (10.86%), gastric ulcer in 06 (6.25%), carcinoma stomach in, carcinoma esophagus in 02(2.17%) and hiatus hernia in patients. The combined use of UGI endoscopy and USG provided a higher diagnostic yield in patients with symptoms related to dyspepsia.functional dyspepsia predominated in females (7%), while as organic dyspepsia predominated in males (62%).Smokers comprised 5(27%) of the dyspepsia patients, out of which 2(.%) had organic dyspepsia and 30(55.56%) had functional dyspepsia. Further, out of 160(80%) patients, who gave history of some psychiatric disorder, 102(51%) belonged to functional dyspepsia group. JK-Practitioner 2012;17(): Key Words: Dyspepsia (functional, organic), upper gastrointestinal (UGI) endoscopy, ultrasonography (USG), duodenal ulcer, gastric ulcer, inflammatory lesions, gastric cancer, cholelithiasis, hiatus hernia. 15

2 INTRODUCTION: 6) Patients with any systemic disease. The clinical observation has revealed that dyspeptic RESULTS: symptoms are quite commonly observed in the A Total of two hundred patients (96 males and 10 Kashmiri population as in other parts of the world. females) in the age group of 37 ± 12.8 years, with Dyspepsia is a very common complaint of patients duration of symptoms ranging from one month to three 1 presenting in both hospital and general practice. It is months were included in the study. 5(27%) dyspeptic very difficult to define dyspepsia and as per Dr.WG patients were smokers, out of which 2(.%) had 2 Thompson dyspepsia defies definition. Dyspepsia may organic dyspepsia. be early symptom of various disease conditions like Ninety percent of all the patients presented with pain peptic ulcer disease, cholelethiasisc and gastric upper abdomen, 8% had epigastric and / or retrosternal carcinoma, denoted as organic dyspepsiabut sometimes discomfort, 0-70% complained of nausea, flatulence, no lesion has been found, denoted as functional belching, vomiting, post prandial discomfort/distension 3, dyspepsia. According to 2006 Rome III criteria, and 30-35% had water brash, weight loss and anorexia. functional dyspepsia must include one or more of In110(55%) patients, food relieved symptoms, while as following symptoms; bothersome postprandial fullness, in 80(0%) patients had aggrevation of symptoms, and early satiation, epigastric pain, epigastric burning with 10(5%) patients had no effect. Besides, 160(80%) no evidence of structural disease including the use of patients gave history of psychiatric disorder ranging upper endoscopy. Criteria should be fulfilled for at least from mild anxiety to depression,out of which 102(51%) 3 months with symptom onset at least 6 months patients belonged to functional dyspepsia group. previously. Since the patients of dyspepsia form a large All the patients were subjected to UGI endoscopy and group of our Medical out patients department, it was a ultrasonography. Functional dyspepsia was observed in relevant and genuine proposition to evaluate these 108(5%) patients and organic dyspepsia in 92(6%) patients, with an aim to study the causes of dyspepsia patients. In functional dyspepsia group, females and to know the diagnostic yield of UGI endoscopy and predominated (7:3), while as in organic dyspepsia USG in detecting the conditions causing dyspepsia. group, males predominated (62:30).Out of 96 males MATERIAL AND METHODS: 3(35.1%) had functional dyspepsia,while as out of Two hundred patients who attended the outpatient 108 females,7(71.51%) had functional dyspepsia and department or were admitted in our hospital with only 30 (28.8%) had organic dyspepsia(table -1). symptoms suggestive of dyspepsia were considered for In the organic dyspepsia group comprising 92 patients, inclusion in the study. The criteria for inclusion in the UGI endoscopy revealed inflammatory lesions study was pain abdomen, discomfort restricted to upper (gastritis, duodenitis, esophagitis and gastroduodenitis) abdomen or heart burn for more than one month in 36(39.13%) patients, duodenal ulcer (including associated with other symptoms like nausea, vomiting, channel ulcers) 3(36.95%) gastric ulcer in 06(6.52%) belching, flatulence, anorexia, dysphagia, water while as gastric carcinoma, esophageal carcinoma and brushes, post-prandial discomfort, distension and hiatus hernia was found in 02(2.17%) patients each. weight loss. History of diet, smoking and drugs Further, ultrasonography revealed gallbladder disease (especially non-steroidal anti-inflammatory drugs) was including cholelithiasis in 10(10.86%) in the organic also enquired from the patients. Each patient underwent dyspepsia group (Table-2). In the organic dyspepsia thorough clinical assessment and routine investigations group, duodenal ulcer predominated in males (25:9) and were performed. All the patients were subjected to UGI so was true of inflammatory lesions, (26:10) while as endoscopy and ultrasonography for ascertaining the females predominated in gallbladder disease (7:3) and investigative diagnosis of dyspepsia either as organic or gastric ulcer (:2) Table 3. functional.

Thus, this study was carried out to establish the investigative diagnosis and ruling out functional dyspepsia by subjecting the patients to UGI endoscopy and ultrasonography. We observed that peptic ulcer disease (combined duodenal and gastric) predominated (3.7%), followed closely by inflammatory lesions (39.13%), gallbladder disease (cholelithiasis) 10.86%, while as other lesions accounted for less percentage of patients in our organic dyspepsia group, in conformity 13, 1 with some other studies as well. Further, an earlier study in the Kashmir Valley has shown the point prevalence of peptic Ulcer disease as.72% and life 15 time prevalence as 11.22%. Reflux esophagitis has been observed to be the second important cause of organic dyspepsia after peptic ulcer disease with gallbladder disease as rare findings some 13, 1, 16 earlier studies.

The present study was percentage of esophagitis in our organic dyspepsia carried out to look for the diagnostic yield of UGI group can be explained on the basis of less number of endoscopy and ultrasonography together in ascertaining patients.

Also, the food habits of most 92(6%) had organic dyspepsia in conformity with Kashmiri population include the consumption of hot above studies.
