Gastrocolic Ligament
The gastrocolic ligament is a portion of the greater omentum that stretches from the greater curvature of the stomach to the transverse colon. It forms part of the anterior wall of the lesser sac. Dividing the gastrocolic ligament provides access to the anterior pancreas and the posterior wall of the stomach. This is commonly done for Whipple procedures, distal pancreatectomy, some forms of the Roux-en-Y gastric bypass, and exploratory laparotomy An exploratory laparotomy is a general surgical operation where the abdomen is opened and the abdominal organs are examined for injury or disease. It is the standard of care in various blunt and penetrating trauma situations in which there may b ....

Transverse Colon
In human anatomy, the transverse colon is the longest and most movable part of the Large intestine#Structure, colon. Anatomical position It crosses the abdomen from the ascending colon at the right colic flexure (hepatic flexure) with a downward convexity to the descending colon where it curves sharply on itself beneath the lower end of the spleen forming the left colic flexure (splenic flexure). In its course, it describes an arch, the concavity of which is directed backward and a little upward. Toward its splenic end there is often an abrupt U-shaped curve which may descend lower than the main curve. It is almost completely invested by the peritoneum, and is connected to the inferior border of the pancreas by a large and wide duplicature of that membrane, the transverse mesocolon. It is in relation, by its upper surface, with the liver and gall-bladder, the greater curvature of the stomach, and the lower end of the spleen; by its under surface, with the small intestine; by its ...

Lesser Sac
The lesser sac, also known as the omental bursa, is a part of the peritoneal cavity that is formed by the lesser omentum, lesser and greater omentum. Usually found in mammals, it is connected with the greater sac via the omental foramen or ''Foramen of Winslow''. In mammals, it is common for the lesser sac to contain considerable amounts of fat.

Pancreas
The pancreas (plural pancreases, or pancreata) is an Organ (anatomy), organ of the Digestion, digestive system and endocrine system of vertebrates. In humans, it is located in the abdominal cavity, abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. Ninety-nine percent of the pancreas is exocrine and 1% is endocrine. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin and pancreatic polypeptide. As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins and lipids, fats in food entering the duodenum from the stomach. Inflammation of the pancreas is kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stomach
The stomach is a muscular, hollow organ in the upper gastrointestinal tract of Human, humans and many other animals, including several invertebrates. The Ancient Greek name for the stomach is ''gaster'' which is used as ''gastric'' in medical terms related to the stomach. The stomach has a dilated structure and functions as a vital organ in the digestive system. The stomach is involved in the gastric phase, gastric phase of digestion, following the cephalic phase in which the sight and smell of food and the act of chewing are stimuli. In the stomach a chemical breakdown of food takes place by means of secreted digestive enzymes and gastric acid. It also plays a role in regulating gut microbiota, influencing digestion and overall health. The stomach is located between the esophagus and the small intestine. The pyloric sphincter controls the passage of partially digested food (chyme) from the stomach into the duodenum, the first and shortest part of the small intestine, where p ...

Whipple Procedure
A pancreaticoduodenectomy, also known as a Whipple procedure, is a major surgical operation most often performed to remove cancerous tumours from the head of the pancreas. It is also used for the treatment of pancreatic or duodenal trauma, or chronic pancreatitis. Due to the shared blood supply of organs in the proximal gastrointestinal system, surgical removal of the head of the pancreas also necessitates removal of the duodenum, proximal jejunum, gallbladder, and, occasionally, part of the stomach. Anatomy involved in the procedure The most common technique of a pancreaticoduodenectomy consists of the en bloc removal of the distal segment (antrum) of the stomach, the first and second portions of the duodenum, the head of the pancreas, the common bile duct, and the gallbladder. Lymph nodes in the area are often removed during the operation as well (lymphadenectomy). However, not all lymph nodes are removed in the most common type of pancreaticoduodenectomy because studies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distal Pancreatectomy
In medicine, a pancreatectomy is the surgical removal of all or part of the pancreas. Several types of pancreatectomies exist, including pancreaticoduodenectomy (Whipple procedure), distal pancreatectomy, segmental pancreatectomy, and total pancreatectomy. History Pancreatic surgeries have been reported as early as the 1800s, however the first successful complete pancreatectomy was reported in 1944. Surgery on the pancreas is complex, at times requiring both the resection, or removal of parts or the entire organ, as well as anastomosis, or the connection of different parts of the digestive system. Advances in technology have allowed for the improvement in outcomes, reduction of complications, and improvement in surgical techniques. Pancreatic anatomy and function The pancreas is a digestive and endocrine organ that serves as a gland. It releases endocrine and exocrine hormones to help with metabolism and digestion. The pancreas is located behind the stomach. It is div ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roux-en-Y Gastric Bypass
Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch, where the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass procedures (GBP). Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food. The operation is prescribed to treat severe obesity (defined as a body mass index greater than 40), type 2 diabetes, hypertension, obstructive sleep apnea, and other comorbid conditions. ''Bariatric surgery'' is the term encompassing ''all'' of the surgical treatments for severe obesity, not just gastric bypasses, which make up only one class of such operations. The resulting weight loss, typically dramatic, markedly reduces comorbidities. The long-term mortality rate of gastric bypass patien ...

Exploratory Laparotomy
An exploratory laparotomy is a general surgical operation where the abdomen is opened and the abdominal organs are examined for injury or disease. It is the standard of care in various blunt and penetrating trauma situations in which there may be life-threatening internal injuries. It is also used in certain diagnostic situations, in which the operation is undertaken in search of a unifying cause for multiple signs and symptoms of disease, and in the staging of some cancers. During an exploratory laparotomy, a large incision is made vertically in the middle of the abdomen to access the peritoneal cavity, then each of the quadrants of the abdomen is examined. Various other maneuvers, such as the Kocher maneuver, or other procedures may be performed concurrently. Overall operative mortality ranges between 10% and 20% worldwide for emergent exploratory laparotomies. Recovery typically involves a prolonged hospital stay, sometimes in the intensive care unit, and may include reha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
