Abstract    Surgical complications including intra-abdominal infection, massive hemorrhage of the alimentary tract or peritoneal cavity, gastrointestinal motility disorders, and delayed wound healing remain the common problems following gastrointestinal surgery. Better understanding the relationship between different complications and their pathogenesis is extremely important. Auxiliary methods such as medical imaging have constantly been used for diagnosis. However， more attention should be paid to clinical symptoms and signs at the early stages of diseases. In addition, the combinations of nonsurgical and surgical strategies in treatment, as well as proper selection of the right operation time and the appropriate surgical procedures, are critical in the management of complications. Although complications following gastrointestinal surgery represent a clinical challenge, most of them can be prevented by rigorous preoperative evaluations, meticulous operations and careful postoperative monitoring.
