Strongest layer of the intestine

Q) Which is the strongest layer of the intestine?

a) Mucosa

b) Submucosa

c) Muscularis propria

d) Muscularis mucosa

Answer:

b) Submucosa is the strongest and most important layer for intestinal anastomosis. It has fibroblasts that will ultimately release collagen and hold the anastomosis together. This layer should be fully incorporated in the anastomosis.

Inverted Vs everted anastomosis of intestine debate has been log going on but now many prefer inverted because mucosa is exposed to mucosa and eventually degrades joining the two submuoca together to cause healing by primary intention.

Endovenous Laser Ablation of varicose veins

Q )  Endovenous Laser Ablation (EVLA)  of  varicose veins is best suited for those :

a) With needle phobia

b) Thrombophlebitis

c) Excess tortuousity

d) Primary varicose veins

Answer

EVLA is thermal ablation of varicose veins in which laser  fibre is inserted in the lumen and ablation is done from inside. It is a good modality for primary and recurrent varicose veins and work in both long and short segments.

This treatment is not effective in cases where there is needle phobia or the veins are having excessive tortuousity or thrombophlebitis. This procedure is done under ultrasound guidance and  wire is passed from the superficial to the deep veins.

Tumescent local anesthesia also helps
