Anastomosis is the connection of two parts of the intestine. It is constructed:

-          after a resection procedure, when the two ends of the bowel are joined to restore continuity of the bowel

-          in palliative surgery, the anastomosis bypasses an inoperable obstruction to the bowel, most commonly a tumour

  According to the reconstruction we differentiate:

- hand made anastomoses

- stapler anastomoses
