Pathophysiology of Distention with risk of rupture
Vasocompression with risk of ischemia?
Hypotension and shock
1.Accumulation of food /secretions above obstruction
2. Swallowed air increases distension
3.Decreased oxygenation decreases peristalsis which further increases distention
•Distension leading to venous compression and decreased oxygenation
•Leakage of compressed capillaries which leak fluid
•Vomiting
•Sepsis also causes vasodilation
What is sepsis?
1.Over growth of commensal bacteria /dead tissue
2.Bacteria move into blood stream
3.They release endotoxins which are vasodilator, and which damage the endothelial
lining causing leakage, and initiation of the clotting mechanism
4.Septic shock

Pilonidal sinus?
Pilonidal means?
Commonly affects?
Can affect what other regions?
Leading causes of ingrowth of hair?
Warning sign?
Pilonidal sinus is a condition where in a hair follicle begins to grow inward, near the
coccyx (tail bone) and can cause a great deal of pain.
Nest of hair
Men between ages 15 and 24
Though the back is most common part of affliction, it may even happen in the navel,
armpits or genital region.
One of the leading causes is the ingrowth of hair. With the increasing amount of time
people spend sitting, not exercising enough, incorrect postures, badly- constructed
chairs, this condition is becoming common. Other topical reasons like obesity,
secondary occupation, family history can also be responsible for this condition.
The warning sign is usually a painless lump. There is usually a fluid filled inside this
cyst. Sometimes, when this fluid drains out, it reduces the pain. This means, the
medication is working, and a continuous antibiotic dosage can fix the problem.
However, some people suffer from chronic sinus, so they have to undergo surgery.
Chances are that the condition will not recur if a surgical procedure is done.
What is a mechanical bowel obstruction?
Most obstructions occur where? and why?
Most common causes of large bowel obstruction?
Mechanical obstruction may be caused by an occlusion of the lumen of the intestinal
tract. Most intestinal obstructions occur in the small intestine and are usually due to
adhesions. Adhesions can develop after abdominal surgery. Obstruction can occur
within days of surgery or years later. Carcinoma is the most common cause of large
bowel obstruction, followed by volvulus and diverticular disease.
What is a non mechanical bowel obstruction?
