Fifty-five patients of mean age 69 (range 41-96) years with rectal cancer (Dukes' A:B:C, 11:24:20) underwent anterior resection using a double stapling technique under the care of one consultant surgeon between 1983 and 1988. The mean distance of the anastomosis from the anal margin was 7.2 (range 4-13) cm. The clinical leak rate was 9 per cent (five patients). There were three postoperative deaths from pulmonary embolism, lower limb ischaemia and renal failure. On prospective follow-up, 35 patients had no evidence of local or systemic cancer a median of 32 (range 24-84) months after operation; seven have died from unrelated diseases and ten from metastatic cancer. Pelvic recurrence, in four patients at 9, 11, 12 and 50 months, has occurred only in association with widespread metastasis. These results suggest that the theoretical risks of an increase in the local recurrence rate of rectal cancer after resection using a double stapling technique are not substantiated.

The aim of this study was to determine the efficacy and long term results of straight colo-anal anastomosis (CAA) after resection for rectal carcinoma as described by Parks. From January 1986 to June 1989, 40 patients underwent this operation: 27 men and 13 women with a mean age of 63.5 years (range 37-81). In 36 cases, the indication was for carcinoma of mid and low rectum and in 4 cases for carcinoma of the upper rectum associated with a low rectal benign tumour (3 Dukes A, 19 Dukes B, 13 Dukes C, and 5 Dukes D). A diverting colostomy was constructed in all cases. Operative mortality was one patient (2.5 per cent) by pulmonary embolism. Anastomotic dehiscence occurred in four patients. None of these patients required reoperation and all colostomies have been closed. 6 patients presented a local recurrence (15.4 per cent) 6 to 34 months after CAA, of whom two were treated by abdomino-perineal resection. 5 patients died 6 to 34 months after CAA from local recurrence (2 cases) or distant metastasis (3 cases) and one patient has liver disease. All others patients are alive free of disease with a mean follow-up of 21.7 months (range 3-46 months). Actuarial survival is 77 per cent at 40 months. Functional results were assessed in the 26 patients followed up more than one year. The mean stool frequency was 2.4 per day (range 0, 3-6). All patients are continent, with a good discrimination gas-stool. 4 patients (15.4 per cent) suffer from soiling, 5 (19 per cent) from stool frequency, and 2 (7.7 per cent) from urgency. In conclusion, CAA is a good alternative of abdominoperineal resection for some mid and low rectal carcinomas. Functional results might be improved by the construction of a colonic reservoir.

From january 1986 to december 1992, 71 patients underwent direct colo-anal anastomosis as described by Parks (CAA) after total rectal resection for carcinoma: 49 men and 22 women with a mean age of 64 years (range 37-82). In 67 cases, the indication was for adenocarcinoma of the mid and low rectum, and in 4 cases for carcinoma of the upper rectum associated with a low rectal benign tumour (6 Dukes A, 36 Dukes B, 21 Dukes C, 8 Dukes D). A diverting colostomy was constructed in all cases. One patient died from pulmonary embolism (mortality: 1.4%). Anastomotic leakage occurred in 6 cases (8.5%). None of these cases required reoperation and all colostomies have been closed. Local recurrence occurred in 12 cases (17%) 6 to 34 months after CAA, of whom 4 were treated by abdominoperineal resection. Eleven patients died from local recurrence (3 cases) or distant metastasis (8 cases). Actuarial survival at 1, 2, 3, 4 and 5 years was 92%, 88%, 78%, 75% and 69% respectively. From the functional point of view, one patient underwent abdomino-perineal resection for incontinence 3 years after CAA. All the other patients were fully continent, with a mean stool frequency of 2 per day, and good gas-stool discrimination. Twenty per cent of patients presented soiling, 20% with stool frequency, and 12% with urgency. Long term functional and oncological results make CAA a good alternative to abdomino-perineal resection for mid and low rectal carcinoma.

In a previous report we found an inverse correlation between pre-operative platelet count (PlC) levels and the risk of post-operative pulmonary embolism in patients undergoing hip surgery. In the present study, we prospectively evaluated the prognostic significance of pre-operative PlC levels on survival in 180 consecutive patients undergoing surgery for colorectal cancer. Other major clinicopathological parameters studied were age, gender, Dukes' stage, duration of surgery, pre-operative haemoglobin levels and transfusion requirements. There were no significant differences in mean pre-operative PlC levels according to tumor stage. Thirty-three patients (18%) died during follow-up (3-23 months, median: 13 months). Univariate analysis (Kaplan-Meier estimates) showed that advanced tumor stage (p < 0.001), duration of surgery (p < 0.05) and a high pre-operative PlC level (p < 0.001) were significantly associated to a poor survival. The multivariate Cox analysis revealed that tumor stage (RR:5.734; 95%C.I.: 2.644-12.44), a high pre-operative PlC level (RR: 2.467; 95%C.I.: 1.117-5.452), and to a lesser extent the patients' age remained independent prognostic variables for mortality. The findings of this preliminary study may be of interest from the point of view of pathogenesis, but also clinically, since they might be used in the decision as to which patients or groups of patients should receive more aggressive therapeutic intervention.
