INTRODUCTIONThe stomach is the most dilated part of the digestive tube and intervenes between Oesophagus and the first part of the duodenum. The stomach acts as a reservoir of food, converts the food into chyme by churning movements and allows the digestion of proteins in to peptones and proteases under influence of hydrochloric acid.The stomach also secretes abundant mucus which act as a protective barrier of mucous membrane. The mucosa of stomach allows some absorption of water, glucose, alcohol and some salts. The stomach secrete a hormone gastrin which regulates the secretion of pepsin and Hcl. An intrinsic factor is eloberated for the absorption of B12 vitamin in the small intestine.1 The stomach is situated in the epigastrium, left hypochondrium and umbilical regions.2 The stomach is a muscular bag relatively fixed at both ends, mobile else-where. The main parts of stomach are fundus, body and pylorus, with greater and lesser curvatures forming left and right borders with the attachment of greater and lesser omentum respectively. In most of the people the stomach is "J" shaped. It receives rich arterial supply from the all three branches of coeliac trunk. Left and right gastric arteries anastomose in the lesser curvature. Right and left gastro epiploic arteries anastomose in the inferior part of greater curvature. The veins drains into the corresponding named vessels which drain in to portal vein. The stomach is also ABSTRACT Background: The morphology of the stomach taken for the study for its clinical interventions like gastro-oesophagial reflux disorders (GERD) which are very common nowadays because of unusual timing of eating food, stress related jobs, eating of junk foods etc. The obesity now considered to be the 2 nd leading cause of death, which can be prevented by gastric reconstructive procedures i.e., the bariatric surgeries. Methods: The study includes 70 adult cadavers, 28 obtained from the formalin fixed specimens kept for anatomy dissection for 1st year MBBS students from 2009 batch to 2015 batch. The remaining 42 specimens obtained from the postpartum bodies in the Forensic department of Guntur Medical College, Guntur. The abdominal cavity opened according to the incisions in the Cunninghams manual of anatomy. Stomach identified by reflecting anterior abdominal wall. Location noted, shape observed, Length taken, relations blood supply noted, results tabulated. Results: 71.4% specimens are "J" shaped, 14.2% are reverse "L" shaped, 7.2% are cresentic shaped, 7.2% are cylindrical shaped observed. The length is more in "J" shaped specimens. The lower extent of greater curvature at L3 in 71.4% specimens, at L2 in 21.4% specimens, at L4 in 7.2% specimens. Conclusions: The present study discussed about the shape of the stomach and the majority of specimens shown "J" shape. Remaining are reverse "L" shape; cresentic and cylindrical shaped.

Helicobacter pylori (H. pylori) has a role in the multifactorial etiology of peptic ulcer disease. A link between H. pylori infection and duodenal ulcer disease is now established. Other contributing factors and their interaction with the organism may initiate the ulcerative process. The fact that eradication of H. pylori infection leads to a long-term cure in the majority of duodenal ulcer patients and the fact that the prevalence of infection is higher in ulcer patients than in the normal population are cogent arguments in favor of it being the primary cause of the ulceration. This study was under taken at the Department of surgery, Narayana medical college, Nellore from January 2007 to July 2008. A total of 150 patients with duodenal ulcers, gastric ulcers, antral gastritis, gastric carcinoma and dyspepsia of any kind were studied. Maximum number of cases were in the age group of 31 years to 50 years among both sexes and number of cases gradually decreased after 50 years of age in males and females. Males were more in number and male to female ratio is (2.75:1) approximately 3:1.

Background: Calculus disease of the biliary tract continues to be a significant health problem. Pigment stones are more common in Eastern studies. Predisposing factors such as cirrhosis, ileal resection are commonly seen in the West; while infection as a cause predominates in South East Asia. In this study we prospectively studied Pigment gall stones to examine the causes for and the role of bacteria in pigment Gall stone diseaseMethods: A hospital based prospective study was carried out from January 1992 to December 1994 at Nizam’s Institute of Medical Sciences, Hyderabad. Institutional Ethics Committee permission was taken. Informed consent was obtained from all selected patients. During the study period a total of 25 consecutive patients with Pigment gall stones were analyzed. Details were recorded in a proforma. Stones were collected from the Gall Bladder with aseptic precautions.Results: Total of 25 patients included, wherein 13 (52%) males and 12 (48%) females. The Median age was 55.5 years and the mean age was 50.2 years. Of 25 patients 11 (44%) had black pigment stones and 14 (56%) had brown stones. 22 (88%) patients presented with biliary colic, and 8 (32%) presented with chronic cholecystitis. At surgery 14 (56%) had a thickened wall suggesting inflammation, 7 (28%) had edema. Bile culture was positive in 11 (44%) patients and stone culture in 5 (20%) patient. Twenty two of 25 patients (88%) had evidence of bacteria on electron microscopy.Conclusions: Whether black stones are associated with higher infection rates or bacteria cause black stones – this question probably would never be answered either on the bench or in the clinicians ward. We, however, can definitely say they are intimately related.
