Abstract:
Prevention of intraoperative incidental injuries during radical operation for rectal cancer and management of postoperative complication are associated with successful operation and prognosis of patients. This paper discusses how to prevent such intraoperative incidental injuries and how to manage postoperative complication. (1) Accurate clinical evaluation should be performed before operation and reasonable treatment decision should be made, including determination of the distance from transection to lower margin of the tumor, T and M staging evaluated by MRI, fascia invasion of mesorectum, metastasis of lateral lymph nodes, metastatic station of mesentery lymph node, association between levator ani muscle and anal sphincter, course and length of sigmoid observed by Barium enema, length assessment of pull-through bowel. Meanwhile individual factors of patients and tumors must be realized accurately. (2) Injury of pelvic visceral fascia should be avoided during operation. Negative low and circumference cutting edge must be ensured. Blood supply and adequate length of pull-down bowel must be also ensured. Urinary system injury, pelvic bleeding and intestinal damage should be avoided. Team cooperation and anesthesia procedure should be emphasized. Capacity of handling accident events should be cultivated for the team. (3) intraoperative incidental injuries during operation by instruments should be avoided, such as poor clarity of camera due to spray and smog, ineffective instruments resulted from repeated usage. (4) As to the prevention and management of postoperative complication of rectal cancer operation, prophylactic stoma should be regularly performed for rectal cancer patients undergoing anterior resection, while drainage tube placement does not decrease the morbidities of anastomosis and other complications. After sphincter-preserving surgery for rectal cancer, attentions must be paid to the occurrence of anastomotic bleeding, pelvic bleeding, anastomotic fistula, ileus, intestinal necrosis and anastomotic stenosis. After sphincter-preserving surgery for rectal cancer, if small amount of bleeding happens, titanium clamp or electric coagulation can be used; if delayed pelvic bleeding occurs obviously, embolism should be applied. Conservative treatment may be used for the non-carcinomatous ileus. When small anastomotic stenosis is found, local treatment is available (finger dilation, balloon expansion, transanal radiated cutting or resection), and for severe stenosis, transadominal operation is required.
