Study Notes

Radiology and Gastrointestinal Disorders

Closed loop obstruction can occur due to volvulus or adynamic ileus, resulting in uniformly dilated intestines that resolve within 36 to 48 hours.
Sigmoid volvulus involves the sigmoid colon twisting on itself, forming an inverted "U" shape, leading to a sausage or balloon-like appearance.
Cecal volvulus involves the cecum twisting around its mesentery, causing distention and shifting within the abdomen.
Pneumoperitoneum, the presence of air or gas in the peritoneal cavity, can be revealed through an upright chest radiograph.
Barium enema procedures involve specific dietary preparations and positioning to visualize the colon.
Different projections and positions are used to visualize specific segments of the colon during barium enema procedures.
Various gastrointestinal disorders, such as Crohn's disease, ulcerative colitis, malabsorption syndrome, diverticular disease, Meckel's diverticulum, and others, can be diagnosed through imaging.
Key details about polyps, colon cancer, peritonitis, Hirschsprung's disease, and imperforate anus are outlined.
Different radiographic examinations, such as cholecystography, cholangiogram, choleography, and cholecystocholangiogram, are used to visualize the gallbladder and bile ducts.
Surgical and postoperative procedures, such as laparoscopic cholecystectomy, operative cholangiography, T-tube cholangiography, and endoscopic retrograde cholangiopancreatography, are described.
Pancreatitis, cholecystitis, cholelithiasis, cirrhosis of the liver, hepatocellular carcinoma, and pancreatic cancer are discussed as possible conditions visualized through radiographic imaging.
The most common type of pancreatic cancer, pancreatic ductal adenocarcinoma, originates in the cells lining the pancreatic ducts.
