A retrospective study of 192 patients operated on by three members of the Edward Wilson Colon and Rectum Unit, Sydney Hospital, was carried out. All operations performed involved dissection within the pelvis. Prophylactic administration of low-dose heparin was used for 71 of these patients. The incidences of clinical thromboembolic disease were 7 per cent in both the group receiving heparin and the other group. In slightly more than half of the patients, pulmonary emboli occurred in the absence of peripheral deep venous thrombosis. It is suggested that the source of these emboli was thrombosis arising in the pelvic veins.

The operative courses of 294 elective consecutive colorectal resections were reviewed in order to evaluate the morbidity and mortality of postoperative thromboembolic complications. All patients received low-dose heparin prophylaxis. Fifty-seven patients were screened for deep venous thrombosis with the fibrinogen uptake test, and treatment of thromboembolism was started if the diagnosis was established by venography and/or pulmonary scintigraphy. Neither the morbidity nor mortality from clinical thromboembolic complications was lowered in the group of patients who were screened. Rectal surgery seems to carry a higher risk of postoperative thromboembolic complications than colon surgery, and thromboembolic complications are responsible for about half of the postoperative deaths following elective colorectal surgery.

A group of 230 patients undergoing elective colorectal surgery was analyzed for the presence of deep venous thrombosis (DVT). Prophylaxis against DVT was practiced with low-dose heparin (either 5000 IU every eight hours, or 5000 IU every 12 hours for seven days) in 199 patients. Prevention of infection was attempted with preoperative administration of Enterobiotic in 155 patients and of Vibramycin in 11 patients. DVT was diagnosed in 46 patients. The frequency of DVT did not differ significantly between patients who underwent resections of the colon and those who underwent rectal surgery. DVT was diagnosed in 27 of the 73 infected patients, which was significantly higher than the incidence of 19 with DVT among the 157 uninfected patients. The frequency of DVT among patients in the two heparin regimens was 15 and 17 per cent respectively, which was significantly lower than with untreated patients. No lethal pulmonary embolism was found and no patient showed clinical signs of embolism. It is assumed that measures aimed at reducing postoperative infection, combined with low-dose heparin, will reduce the incidence of postoperative DVT after colorectal surgery.

Colorectal cancer is the third most common malignancy in men and women and accounts for 10% of all cancer deaths. The primary risk factor for colorectal cancer is advancing age, but other factors also play a role in its development, including genetic predisposition, smoking, alcohol consumption, obesity, and high-fat, low-fiber diet. Colon cancer survival is primarily related to the stage of disease at diagnosis. The main screening tests for colon cancer are fecal occult blood testing, flexible sigmoidoscopy, double-contrast barium enema, and colonoscopy. The pre-operative evaluation should include a complete blood count, carcinoembryonic antigen (CEA), colonoscopy, and chest radiograph. Other preoperative evaluations are patient specific or of unproven benefit. The operative procedure should include a bowel preparation, parenteral antibiotics, and deep venous thrombosis prophylaxis. The procedure performed must be tailored to the location of the colon cancer but should include complete, en bloc resection of the cancer and its lymphatic drainage, including locally invaded structures. The bowel margins of resection should be at least 5 cm from the tumor to minimize anastomotic recurrences. Laparoscopic colectomy has been shown to be as safe and effective as open colectomy for the treatment of colon cancer. The use of sentinel lymph node biopsy is feasible but has not yet been proved clinically useful. Surveillance after surgery for colon cancer is necessary to monitor for metastatic disease or local recurrence. Several groups have made surveillance recommendations including office visits, colonoscopy, and CEA monitoring.

Obesity is a medical epidemic with an enormous impact on disease prevalence and health care utilization. In the preoperative period, an awareness of medical issues associated with obesity is an important part of the planning for surgical procedures. The authors highlight the diagnostic and treatment options for medical conditions commonly affecting the obese patient including diabetes, hypertension, coronary artery disease, and deep venous thrombosis.

Venous thromboembolism (VTE) can occur after major general surgery. Pulmonary embolism is recognized as the most common identifiable cause of death in hospitalized patients in the United States. The risk of deep venous thrombosis (DVT) and pulmonary embolism (PE) is higher in colorectal surgical procedures compared with general surgical procedures. The incidence of venous thromboembolism in this population is estimated to be 0.2 to 0.3%. Prevention of VTE is considered a patient-safety measure in most mandated quality initiatives. The measures for prevention of VTE include mechanical methods (graduated compression stockings and intermittent pneumatic compression devices) and pharmacologic agents. A combination of mechanical and pharmacologic methods produces the best results. Patients undergoing surgery should be stratified according to their risk of VTE based on patient risk factors, disease-related risk factors, and procedure-related risk factors. The type of prophylaxis should be commensurate with the risk of VTE based on the composite risk profile.
