You perform a vagotomy (sectioning of the vagal trunks) to improve you patient’s gastric ulcer situation. How could this procedure reduce your patient’s symptoms?
Would the functioning of the descending colon be affected by this procedure?
The vagus nerve supplies parasympathetic innervation to the GI tract up to the proximal 2/3 of the transverse colon – secretion of acid is modulated by the parasympathetic system.

Patients who have perforated gastric ulcers are often propped up in bed. In anatomical terms, explain the reason for a patient being placed in this position.
Suppose you detect a collection of infected material in the peritoneal cavity in the region of the anterior surface of the second part of the duodenum. Indicate the pathways along which the material may spread to reach the:
a) undersurface of the diaphragm
b) the pelvic cavity
Sit the patient up so that the stuff drains downwards.
To get to the udersurface of the diaphgragm, fluid would need to exit at the epiplioc foramen of Carl Winslow and into the hepatorenal recess (of Morrison).
To get to the pelvic cavity, fluid would need to exit the foramen, travel down the paracolic gutters and into the pelvis.

A mother brings her 2-week old baby to the pediatrician because he exhibits “projectile vomiting” of curdled milk (milk mixed with gastric acid) stained with bile. You suspect an obstruction somewhere along the baby’s GI tract. An X-ray shows a “double-bubble” sign in which both the stomach and part of the duodenum is extended.
- What do you suspect could be the problem with this child?
- Which other abnormal conditions might explain his problems?
Obstruction of the duodenum beyond the hepatopancreatic ampulla: annular pancreas or SMA syndrome or duodenal atresia.
check the double-bubble sign in the photo…

D. Tracheoesophageal fistula

C. Hypertrophied pyloric sphincter
Choking or aspiration pneumonia could be due to:
●Esophageal Atresia (EA) – congenital malformation that represents the failure of the esophagus to develop a continuous passage into the stomach
●Tracheo-esophageal Fistula (TEF) – malformation where the trachea and esophagus fails to separate into distinct structures and a passage is created between them
A 47 year old obese man experiences nausea, vomiting, abdominal distension and stabbing pain after eating. It appears to be relieved when he leans forward or puts his knees to his chest.
A CT scan reveals a dilated superior mesenteric artery and you diagnose the patient with Superior Mesenteric Artery Syndrome.
Why would the SMA cause these symptoms? Which other problems might result from a dilated SMA?
SMA syndrome compresses the third part of the duodenum –> distension of the 1st and 2nd parts of the duodenum, nausea, comiting, etc.
Other symptoms like hematuria can result from compression of the left renal vein, which the left gonadal vein drains into –> edema of the left testicle or artery.

- Can you explain why the pain of appendicitis is felt first in the periumbilical area and then shifts to the right lower quadrant?
- Why were the muscles of the anterior abdominal wall rigid?
The appendix is part of the midgut and supplied by a branch of the SMA. The lesser splanchnic nerve (T10,T11) supplies the midgut and visceral sensory fibers travel back to these spinal cord levels to give referred pain around the umbilicus.
