Administrative aspects of a general surgical firm: an audit of accuracy of operation lists and timeliness of discharge summaries.

A one-year audit of operation lists and discharge summaries of one surgical firm showed only 1.4 percent of operation lists contained errors or omissions and only 5 percent contained abbreviations. 74.2 percent of discharge summaries were dictated within one week of discharge. A high proportion of day cases allowed 44.7 percent of the discharge summaries to be dictated on the day of operation. Close consultant and secretarial involvement in the preparation of operating lists can ensure a high degree of accuracy. Day case operation notes should be combined with a discharge letter to optimise communication with general practitioners.

Leakage from stapled low anastomosis after total mesorectal excision for carcinoma of the rectum.

Over 14 years 276 patients with rectal cancer underwent surgery; 219 who underwent low anterior resection of the rectum with total mesorectal excision were studied. There were 24 (11.0 per cent) major anastomotic leaks associated with peritonitis or a pelvic collection and 14 (6.4 per cent) minor leaks that were asymptomatic and detected by contrast enema. All major leaks occurred at an anastomotic height of less than 6 cm (P = 0.08). The abdominoperineal excision rate was 9.1 per cent. Major leaks were associated with failure to defunction in 11 of 62 patients and with a defunctioning colostomy in 13 of 157 (P = 0.03). Of the 24 patients with major leaks seven developed peritonitis, one with a defunctioned anastomosis (P = 0.002), and three died (P = 0.02). Use of the sigmoid colon led to major leakage in seven of 32 patients compared with 17 of 187 when the splenic flexure was employed (P = 0.05). There was no increase in the local recurrence rate but only nine patients with major leakage and a temporary stoma have had these closed. Key technical factors include: a clean dry pelvic cavity, pulsatile colonic blood supply, suction drainage started during closure and mobilization of ample tissue to fill the pelvic space.

The timing of breast cancer surgery within the menstrual cycle.

The effects of the timing of surgery, fine needle aspiration cytology (FNAC) and mammography within the menstrual cycle were investigated retrospectively in 211 premenopausal breast cancer patients. The day of surgery within the menstrual cycle was known for 157 women whose menstrual cycles were regular. Recurrence and survival were closely similar whether surgery was performed during days 3-12 or at other times (days 0-2 or 13-32) in the cycle. Outcome was also unrelated to the timing of mammography which was known in 101 cases. There were no significant differences in recurrence or survival associated with the timing of FNAC when all patients were considered. In the subset of lymph node negative patients (n = 32), however, FNAC outside days 3-12 was associated with a significantly decreased rate of relapse (RR = 0.25, 95% CI = 0.07-0.9) and death (RR = 0.10, 95% CI = 0.02-0.9). These patients, however, also had significantly smaller tumours (median = 2 cm, interquartile range = 2-3 cm) than patients having FNAC on days 3-12 of the cycle (median = 3, interquartile range = 2-4) (Mann-Whitney: z = 2.11, P = 0.04). We have not confirmed that surgery or FNAC during days 3-12 of the cycle is associated with a poorer outcome than interventions during other parts of the cycle.

Flush aortic tie versus selective preservation of the ascending left colic artery in low anterior resection for rectal carcinoma.

The effects of two methods of colonic vascular ligation were studied in 143 consecutive patients who underwent low anterior resection with total mesorectal excision and full mobilization of the splenic flexure. Either the ascending left colic artery (ALCA) was selectively preserved (n = 52) or a flush aortic ligation was performed (n = 91). In those with a protective colostomy, the radiological leak rate was 12 per cent when the ALCA was preserved (n = 41) and 10 per cent when a flush aortic tie was performed (n = 60) (P greater than 0.95; 95 per cent confidence interval (c.i.) for difference -10 to +15 per cent). In those without a colostomy, the clinical leak rates of 9 per cent when the ALCA was preserved (n = 11) and 19 per cent when a flush aortic tie was performed (n = 31) were not significantly different (P greater than 0.10; 95 per cent c.i. for difference -12 to +32 per cent). Proportional hazards analysis showed no association between the method of vascular ligation and the risk of tumour recurrence and death. Anastomotic leak rates, tumour recurrence and survival were not related to the method of vascular ligation.

The diagnosis of femoral hernia.

The accuracy of diagnosis of femoral hernia in referrals to a district general hospital over a period of 5 years has been studied and related to clinical outcome. A correct diagnosis was made in only 36 of 98 cases (60 urgent, 38 routine) before admission to hospital. A correct pre-operative diagnosis was ultimately made in 85 cases. Four patients, all urgent admissions with incarcerated bowel, died within 30 days of operation. In none of these cases was a correct diagnosis made before admission to hospital. The median length of post-operative stay of urgent admissions was 7 days (range 4-50) when a correct initial diagnosis was made and 10 days (range 4-50) when the initial diagnosis was incorrect (P = 0.07, Mann-Whitney test). When strangulated small bowel was found at operation, 70% of those with an incorrect initial diagnosis (n = 23) required resection, as compared with 20% of those with a correct initial diagnosis (n = 10, P = 0.014, chi 2 with Yates' correction). Femoral hernias are frequently incorrectly diagnosed before hospital admission and this is associated with worsened outcome in urgent cases.

What are the benefits of routine breast cancer follow-up?

The value of follow-up after potentially curative treatment of breast cancer remains controversial. Recurrence-free women (n = 402) attending a breast clinic over a 3 month period were studied. The women attended 423 appointments, 412 of which were routine. Eleven were requested by the patient or general practitioner (interval appointments). All 11 interval and 19 of the routine appointments resulted in investigations for possible recurrence. Three (27%) interval appointments and four (1%) routine appointments resulted in the diagnosis of a recurrence (P < 10(-5). The attitudes of 285 patients to follow-up were investigated by questionnaire. Two hundred and twenty-three (78%) questionnaires were completed. Regular follow-up in the breast clinic was preferred to attendance only when symptomatic by 190 (85%) women and 169 (76%) preferred regular breast clinic visits to general practitioner follow-up. Most women (n = 174) (81%) said they felt reassured and less anxious having attended the breast clinic. Routine follow-up after potentially curative treatment of breast cancer is inefficient in the detection of recurrence. It is, however, highly rated for providing reassurance and reducing anxiety. Reassurance rather than detection of recurrence may be the most important function of the breast cancer follow-up clinic.

Which surgeons avoid a stoma in treating left-sided colonic obstruction? Results of a postal questionnaire.

There is now good evidence to indicate that the majority of patients with large bowel obstruction can be safely managed by resection and immediate anastomosis, but have surgeons embraced this policy? A postal survey has been performed to ascertain the opinions of consultant general surgeons within the Wessex region regarding the management of left-sided large bowel obstruction. Of 47 questionnaires sent, 42 replies could be analysed. In patients of good anaesthetic risk, 90% would perform resection with primary anastomosis if the lesion was at the splenic flexure, and 62% would adopt this policy for a rectosigmoid obstruction. In patients of higher anaesthetic risk these figures fell to 71% and 31%, respectively. Surgeons with a gastrointestinal interest were more likely to recommend resection with primary anastomosis. However, this trend reached statistical significance only for splenic flexure and descending colon lesions in good-risk patients. Most surgeons would avoid a stoma in the presence of liver metastases, and only three would be more likely to create a stoma in this situation.

Risk of peritonitis and fatal septicaemia and the need to defunction the low anastomosis.

The aim of this study was to investigate the need to defunction the low anastomosis after anterior resection of the rectum with total mesorectal excision for rectal cancer. Two hundred consecutive patients (125 defunctioned, 75 non-defunctioned) undergoing low anterior resection for carcinoma were included in the study. Peritonitis requiring emergency laparotomy occurred in 8 per cent of the patients who did not have a defunctioning stoma compared with less than 1 per cent of those patients who had a defunctioning stoma (P less than 0.01). There was no mortality related to closure of the stoma but seven patients developed a faecal fistula and ten developed an incisional hernia. Despite current trends to avoid the defunctioning stoma, these results suggest that after total mesorectal excision the faecal stream should be temporarily diverted away from the anastomosis that is 6 cm or less from the anal verge to protect against potentially life-threatening anastomotic leakage.

A randomized prospective study to compare ceftizoxime with cephradine as single dose prophylaxis in elective cholecystectomy.

This study compares the efficacy of ceftizoxime with that of cephradine as single agent prophylaxis in elective cholecystectomy. The incidence of purulent wound infection was low in both groups (ceftizoxime 1/99; cephradine 2/92). No adverse reactions to the trial antibiotics occurred in either group. Ceftizoxime is a safe, effective, convenient and well-tolerated antibiotic for use as single agent prophylaxis in elective cholecystectomy. However, because it has no demonstrable advantage over cephradine and is three times as expensive, its routine use is not justified.

Wound infection following high saphenous ligation. A trial comparing two skin closure techniques: subcuticular polyglycolic acid and interrupted monofilament nylon mattress sutures.

A prospective, randomized trial was performed to compare the incidence of wound infection following skin closure with subcuticular polyglycolic acid and interrupted monofilament nylon mattress sutures in patients undergoing high saphenous ligation (126 patients; 75 polyglycolic acid wounds, 86 interrupted monofilament nylon mattress wounds). By 6 weeks after operation, pus had discharged from 15 (20%) polyglycolic acid wounds compared with seven (8%) interrupted monofilament nylon mattress wounds (P = 0.05), giving an overall infection rate of 13.7%. Infection occurred in 23% of the 56 procedures performed by the two surgeons with the highest infection rates compared with 8% of the 105 procedures performed by the remaining nine surgeons (P = 0.02). The excess of infections in wounds closed with subcuticular polyglycolic acid was caused by an excess of infections in operations performed by the two surgeons with the highest infection rates. The higher infection rate found with subcuticular polyglycolic acid appeared to be operator dependent.

Sigmoid invasion as a late complication of mucinous cystadenoma of the appendix. Report of a case.

A cystic mass arising from the right iliac fossa was an incidental finding at laparotomy and was treated conservatively after a biopsy had shown no evidence of malignancy. Nine years later the patient presented with shock and colonic bleeding. A large cystic lesion arising from the vermiform appendix and invading the sigmoid colon was found and excised. Histologic examination indicated that the underlying lesion was an inflamed mucinous cystadenoma of the appendix. Frank invasion of viscera by such lesions has not previously been described. Complications of such lesions and their association with other colonic neoplasms are discussed.
