Study Notes
Radiography and Gastrointestinal Disorders Summary
- Closed loop obstruction can result from volvulus or adynamic ileus, causing uniformly dilated intestines that resolve within 36 to 48 hours.
- Sigmoid volvulus involves the sigmoid colon twisting on itself, forming an inverted "U" shape and losing its normal haustral markings, leading to a sausage or balloon-like appearance.
- Cecal volvulus involves the cecum twisting around its mesentery, becoming distended and shifting up and to the left within the abdomen.
- Pneumoperitoneum, with air or gas in the peritoneal cavity, can be revealed by an upright chest radiograph.
- Barium enema for evaluating the colon involves a low residue diet, clear fluid diet, laxative colonic lavage if necessary, and specific positions for tube insertion.
- Different radiographic projections and positions are used to demonstrate specific aspects of the colon, such as the right colic flexure, ascending colon, left colic flexure, and other areas.
- Various gastrointestinal disorders, including Crohn's disease, ulcerative colitis, malabsorption syndrome, diverticular disease, Meckel's diverticulum, intussusception, and different types of polyps, are discussed.
- Predisposing factors for colon cancer include ulcerative colitis, familial polyposis, and genetic factors, with 75% of cases occurring in the recto-sigmoid region.
- Peritonitis, Hirschsprung's disease, and imperforate anus are mentioned as other gastrointestinal conditions.
- Cholecystography, cholangiogram, choleography, cholecystocholangiogram, percutaneous transhepatic cholangiography, laparoscopic cholecystectomy, operative cholangiography, T-tube cholangiography, and endoscopic retrograde cholangiopancreatography are described as diagnostic and treatment procedures for gallbladder and biliary disorders.
- Pancreatitis, cholecystitis/cholelithiasis, cirrhosis of the liver, and hepatocellular carcinoma are detailed as liver and pancreatic disorders.
- The text also mentions the most common type of pancreatic cancer, pancreatic ductal adenocarcinoma, and its origin in the pancreatic ducts.
