“…Among them are the effects of substances on healing anastomosis phases, such as antibiotics (2) , hormonal and non-hormonal anti-inflamatories (3,4,5) , antioxidants (6) , anti-neoplasics (7) , imuno-suppressor drugs (8) , and hormones (9) . Other factors that interfere with intestinal anastomosis are also being studied, such as shock (10,11) , peritonite (12,13,14) , and adherences action (15,16) . In addition to these factors, local secondary hypoxy related to a decrease in sanguineous perfusion is an important agent that can cause anastamotic complications (10,17,18,19,20,21,22,23) .…”
