sphincter of the stomach
pyloric sphincter = between pylorus and duodenum
ligament of Treitz
suspensory muscle of the duodenum = end of upper gastrointestinal system
omenta
layers of fatty connective tissue called peritoneum that attach to the stomach. provides extra support and protection by lining the abdominal cavity and surrounding organs
greater omentum
attached to greater curvature of the stomach and hangs over the intestines, you must move this to access the intestines or abdominal organs
lesser omentum
attached to the lesser curvature of the stomach and to the liver and forms a protective and supportive covering to the abdominal organs
what protects the abdominal organs
omentum
what is the largest vessel in the abdoment
abdominal aorta (extension of thoracic aorta)

left gastric artery has how many branches
1
how common is gastric cancer
4th most common cancer worldwide
true or false obesity has tripled around the world since 1975
tru
how many adults worldwide are obese
1.9 billion
9 complications of obesity
diabetes, hypertension, hyperlipidemia, fatty liver disease, sleep apnea, GERD, arthritis, inflammatory and autoimmune disease, cancer
lesser curvature blood supply
- inferior = right gastric artery off hepatic artery off the common hepatic
- superior = left gastric artery (branch of cephalic)
cardia blood supply
left gastric artery
hypertension
high blood pressure - prolonged exposure = damage to artery walls and atherosclerosis (plaque buildup)
stroke, heart failure
hyperlipidemia
high cholesterol = higher than average levels of lipids(fat) in the blood stream
LDL cholesterol damage artery walls and contribute to plaque buildup
coronary artery disease, stroke, heat attack
stomach cancer cause
unclear. thought to be related to H pylori
age 60+
excess tobacco and alcohol
diet high in salt
prior stomach surgery for an ulcer
gender men>women
family history
race common in black hispanic and asian people
symptoms of stomach cancer
indigestion/heart burn
abdomen pain
nausea
diarrheaa
bloating
loss appetite
sensation of food getting stuck in the throat while eating
weakness/fatigue
vomiting blood
Anastomosis
join together two hallow organs usually to restore continuity after resection or the bypass an unresectable disease process
where/when are anastmoses performed
- blood vessels
- GI tract (esophagus, stomach, small bowel, large bowel, bile ducts, pancreas)
- urinary tract
types of anastomeses
- end to end
- end to side
- side to side
- functional end to end
how many types of anastomoses are there
4
what is the angle of his
the acute angle created between the cardia at the entrance of the stomach and esophagus
how many sphincters in the stomach
2
what are the sphincters in the stomach
- pyloric sphincter
- esophageal sphincter
ligament of treitz
suspensory muscle of the duodenum = marks the end of the upper gastrointestinal system
the most common form of anastomosis
end to end
end to end anastomoses
most common form. the ends of the tubular structures are sutured together at the point of incision
this anastomosis joins the end to the side
end to side
end to side
this anastomosis joins the end of a tubular structure to the side of another structure.
when is end to side anastomosis used?
bariatric procedures (gastric bypass)
side to side
joins the sides of two structures.
when is side to side used
gastric bypass (joining of two portions of jejunum
functional end to end
bowel is mobilized bowel ends are approximated, a common stoma (opening) is created, and finally the common opening is closed
when is functional end to end used?
bowel resection
gastrojejunostomy
a small part of the stomach is used to create a new stomach pouch connected directly to the jejunum
gastric bypass access steps:
- identify trocar sites and insert to gain access
- mobilize the upper portion of stomach and take down adhesions
goals of the gastric bypass access steps
- safe laproscopic entry w/o injury to viscera or other internal structures
- maintain pneumoperitoneum
- optimize visualization
- gain exposure and mobilize the upper portion of the stomach in preparation for stapling
- provide reliable hemostasis and minimize thermal damage to surrounding tissue
steps for gastric repair (7)
- create gastric pouch
- transect the jujunum
- transect the jujunal mesentery and create the enterotomies in prep for the jejunojejunostomy
- perform jejunojejunostomy and close the otomy
- create the otomoies in the stomach pouch and jujunum
- perform the gastrojejunostomy
- perform a leak test
Jejunojejunostomy
a surgical technique used in an anastomosis between two portions of the jejunum
steps of gastric bypass closure
- close mesentary defects, and place any drains
- close trocar defects
- apply topical skin adhesive
surgical goals of gastric bypass repair gastric pouch step
- maintain compression to ensure uniform leak free hemostatic staple line
- achieve good consistent staple lines in wide range of tissue thickness
surgical goals of gastric by pass transcect jujunum step
- maintain appropriate compression to ensure uniform hemostatic staple lines
- fully transect the jejunum
surgical goals of gastric by pass transect jejunal mesentary step (3)
- transect and seal the mesenteric vessels
- minimize trauma to surrounding tissue and structures
- create an otomy in the small bowel to facilitate the creation of the jejunojejunostomy
surgical goals of gastric bypass jejunojejunostomy and close ostomy step
- hemostatic and secure staple lines
- secure, leak free anastomosis
- secure, fluid-tight closure of the otomy
surgical goals of gastric bypass create stomach ostomies step
- minimize thermal damage to surrounding tissues
- hemostatic, secure, leak free anastamosis
- achieve good consistent staple lines in a wide range of tissue thickness
surgical goals of gastric bypass perform leak test step
- confirm integrity of anastomosis
- control any bleeding oozing
surgical goals of gastric bypass close mesentery defects step
- prevent postoperative intestinal herniation
- evacuate any blood or fluid from the abdominal cavity to identify staple line issues
surgical goals of gastric bypass closed trocar step
- prevent wound dehiscense while maintaining tight closure
- address risks associated with surgical site infection, trocar site herniation
surgical goals of gastric bypass apply topical skin adhesive step
- added strength and protection to incisions
- help address risk factors for postoperative
