Prevention of SSI is key to successful surgery.

One application of alcoholic antiseptic reduces bacterial count by 95% and is enough. Adequate time should be given to it to dry.

Shaving should be done just before the surgery

Razors should not be used for hair removal. Clippers should be used.

4)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.
