Fulltext PDFAnastomotic Leakage (AL) is one of the most dreaded postoperative complications in colorectal surgery. The reported leak rate ranges from 1% to 30%. Local blood supply is one of the crucial factors for bowel anastomosis healing [1-2]. Poor local tissue oxygenation secondary to inadequate anastomotic vascular perfusion seems to play a key role in the determination of anastomotic viability [3]. The most widely used “technique” to evaluate tissue perfusion is surgeon’s intraoperative visual judgment based on clinical findings, such as colour, bleeding edges of resected margins, pulsations and temperature. Studies have proven that operating surgeon’s clinical judgment usually underestimates the risk of anastomotic leak in colorectal surgery [4].The ligation of Inferior Mesenteric Artery in left sided colonic resections devoid the blood supply of descending colon and this part of colon relies entirely on collateral blood supply from proximal territory through marginal arcades. Other factors affecting the vascular supply of colon includes increasing age with existing vascular pathology, previous radiation, diabetes and other systematic cardiovascular and autoimmune disorders.
