Jass staging is a predictor of outcome following "curative" resection of Dukes' B colorectal carcinoma.

BACKGROUND AND AIMS: We have sought to determine if the addition of the Jass pathological classification to Dukes' staging would provide improved prognostic information for patients undergoing curative surgery for Dukes' B colorectal carcinoma. PATIENTS AND METHODS: One hundred and eighty three patients who underwent curative surgery for Dukes' B colorectal cancers between December 1988 and January 1998 were identified. An assessment of Jass scoring was made at the time of initial histological staging. All patients entered a comprehensive follow-up system. RESULTS: Jass grouping was found to correlate significantly with cancer specific mortality rates; group III having a worse prognosis than groups I and II (p<0.005). There was no significant difference between either local recurrence or systemic recurrence and the Jass group. CONCLUSION: The Jass classification provides additional prognostic information in patients following curative resection of Dukes' B colorectal carcinoma and may therefore facilitate the selection of patients who will benefit most from adjuvant treatment

Multiple, large, benign peritoneal cysts--a case report.

This case report describes a unique case of large (up to 17 cm!) peritoneal cysts of uncertain aetiology. It illustrates the diagnostic and management difficulties encountered with such a rare problem. Although subsequently proven to be benign, they were thought to represent an extreme form of endosalpingiosis after a literature review.

Acetylsalicylic acid and dipyridamole improve the early patency of aorta-coronary bypass grafts. A double-blind, placebo-controlled, randomized trial.

A total of 125 patients undergoing aorta-coronary bypass grafting for disabling angina were randomized to receive either 330 mg of acetylsalicylic acid (aspirin) plus 75 mg of dipyridamole three times daily or a placebo for 6 months postoperatively. In addition, all patients were given warfarin for 3 months. Repeat angiography was performed at 6 months in 103 patients. In the treatment group 95 grafts were implanted in 48 patients, of which 87 were patent (91.6% patency rate). This figure compares with 88 grafts patent out of 118 implanted in 55 patients in the placebo group (74.6% patency rate) (p less than 0.01). We conclude that antiplatelet therapy improves the early patency of saphenous vein aorta-coronary bypass grafts.

Does oxpentifylline ('Trental') have a place in the treatment of intermittent claudication?

In a randomized double-blind study, the clinical and haemorrheological responses of 40 patients receiving oxpentifylline (200 mg 3-times daily) were compared with those of 40 patients receiving placebo. The treatment period in both groups was 2 months. The parameters measured before and after treatment were: subjective response; claudication and maximum walking distances; ankle systolic indices; maximum blood flow in the lower limb by gravimetric plethysmography; plasma fibrinogen; erythrocyte deformability and whole blood viscosity. There was a significant increase (p less than 0.05) in mean erythrocyte deformability in the oxpentifylline group but not in the placebo group; this apparent difference between the groups, however, was not significant. The placebo group showed a significant improvement (p less than 0.05) in claudication distance and mean plasma fibrinogen concentration, but no such improvements were observed in the oxpentifylline group. There were no significant differences in either of the two groups with regard to the subjective response, ankle systolic indices, maximum limb blood flow or whole blood viscosity. It is concluded that oxpentifylline , when taken in oral form at the dose used in this study, increased erythrocyte deformability without conferring any clinical or haemorrheological benefit to patients with intermittent claudication.

Endoscopically monitored percutaneous dilational tracheotomy in a residency program.

OBJECTIVES/HYPOTHESIS: Endoscopically guided percutaneous dilational tracheotomy (PDT) has become a well-established alternative to the more traditional open tracheotomy, yet its use by otolaryngologists is limited. As airway management specialists, otolaryngologists should be familiar with a wide range of definitive procedures, including PDT. Few otolaryngology programs teach the technique. The objective of the present study was to determine the complication rate and outcome of PDT after its introduction in a residency teaching program. We also wished to evaluate whether the time savings reported by experienced surgeons could be repeated in our setting. SETTING: Tertiary referral teaching hospital. METHODS: We prospectively reviewed our first 54 consecutive PDTs and compared them to 29 consecutive standard open tracheotomies, which were reviewed retrospectively. RESULTS: Complications (13% vs. 33%, P = .030), operative time (12 vs. 24 min, P < .0001) and total procedure time (37 vs. 80 min, P < .001) were significantly reduced in the PDT group as compared with standard tracheotomy. Initial outcome data were equal in both groups. CONCLUSIONS: We found that PDT can be safely and effectively taught as part of an otolaryngology residency training program.

Chest radiographs after dilatational percutaneous tracheotomy: are they necessary?

BACKGROUND: The efficacy of routinely obtaining chest radiographs after standard open tracheotomy has been questioned. Recent literature would suggest that after a routine, uncomplicated tracheotomy, chest radiography is a low-yield procedure that incurs unnecessary expense. Percutaneous dilatational tracheotomy (PDT) is rapidly replacing open tracheotomy as the intensive care unit procedure of choice for airway management. Complication rates are equivalent between the two procedures. OBJECTIVE: We examined the value and cost-effectiveness of routine postoperative chest radiographs in patients undergoing PDT. STUDY DESIGN AND SETTING: The study was a prospective analysis of 54 consecutive PDTs performed at a tertiary care academic institution. RESULTS: Eighteen (33%) patients had chest radiographs obtained within 1 hour of PDT (6 at the request of the otolaryngology service); 35 (66%) underwent radiography more than 2 hours later at the request of the intensive care unit for reasons other than PDT. There were no incidents of pneumothorax, pneumomediastinum, or tracheotomy tube malposition in any patient. Patients undergoing chest radiography within 1 hour of the PDT also had chest radiographs within 12 hours at the request of ICU staff for their underlying disease. CONCLUSIONS: Routine chest radiography after PDT is of low yield. Because most of these patients require chest radiographs for their underlying disease within 12 hours, a cost savings of approximately $13,500 would be realized in this patient population. SIGNIFICANCE: Routine chest radiography after PDT is unwarranted in most cases.

Closure of transverse loop colostomy and loop ileostomy.

The aim of a defunctioning stoma is to protect patients from the consequences of faecal leakage and pelvic sepsis, should it occur. A retrospective audit of 77 patients who had undergone closure of a loop stoma between 1988 and 1996 was performed. Sixty patients had either transverse loop colostomy (52) or loop ileostomy (8) to defunction distal colorectal/anal anastomoses or pathology, and 17 patients had a loop ileostomy to defunction an ileoanal pouch. Those who had restorative proctocolectomy experienced a much higher (24%) complication rate than the loop colostomy group (5%), despite similar perioperative care and surgery performed by surgeons of equivalent seniority. The complication rate of ileostomy closure in pouch patients is similar to other published series. As a result of these findings, a selective approach to the use of loop ileostomy to protect pouches has been introduced. The absence of wound infections in our series would suggest that primary closure of the stomal wound without drainage can be achieved.

Maximum surgical blood ordering schedule in a district general hospital saves money and resources.

A 6-month prospective audit was carried out in three surgical departments of a district general hospital. Over that period, 2720 units of red cells were electively cross-matched, 957 being transfused. The overall cross-match-to-transfusion ratio (CTR) was 2.8, but this varied from over 40 for some gynaecological procedures to 1.5 for major surgical procedures. The average CTR for general surgery was 2.2, orthopaedics 2.3, and obstetrics and gynaecology 5.7. A maximum surgical blood ordering system (MSBOS) was introduced and a second 6-month audit carried out. The number of units cross-matched had fallen by 36% to 1746, with a CTR of 1.8. The change in activity had led to a saving conservatively estimated at 11,616.00 Pounds per annum. Local audit and the introduction of a MSBOS in a district general hospital is an exercise which can demonstrate inefficiencies in blood ordering practices and can lead to large financial savings without detracting from standards of patient care.

High density lipoproteins and exercise.

High density lipoprotein (HDL) and total cholesterol (TC) levels have been measured and their ratio compared in four groups of subjects - those with vascular disease, controls, middle-aged "keep-fit" enthusiasts and young physical education students. Each group has also been subjected to analysis of risk factors known for atherosclerosis. The HDL level was significantly raised in the Athletic and Exercise groups even though the latter were more overweight and had the highest total cholesterol level. This would appear to indicate that exercise may exert its protective effect against atherosclerosis, at least in part, by elevating the HDL level above a certain critical level. The HDL/TC ratio was significantly lower in the Vascular group and we would advocate that any ratio less than 20% is highly suspicious of atherosclerosis. We suggest that both the HDL level and HDL/TC ratio should be viewed together as reflecting the risk of atherosclerosis.

Postanal repair: which patients derive most benefit?

Forty-two patients (37 women, 5 men; mean age 61 years) with varying degrees of anal sphincter dysfunction were treated by postanal repair. Results were analysed in relation to age, sex, presenting complaint and the results of preoperative anorectal physiological tests. Complete continence was restored in 13 (31%), while acceptable but slightly impaired control was achieved in a further 17 (40%). Twelve patients (29%) remained or became totally incontinent. The likelihood of a successful outcome was greater in those presenting with complete incontinence (77% improved) than in those retaining control of solid stool (29% improved, 29% unchanged, 43% worse). Age and sex had no effect on results but pudendal neuropathy, identified in 74% overall, slightly reduced the chance of success. In nine postoperative patients studied, neither the anorectal angle nor anal canal length bore any relation to the results of surgery.

The value of laparoscopy under local anaesthesia in 250 medical and surgical patients.

This study reports our experience of laparoscopy under local anaesthesia in 250 patients; the procedure was safe, quick and easy to perform with minimal inconvenience to the patient. We advocate the early use of laparoscopy in patients with ascites and when there is difficulty in the diagnosis of patients with jaundice and hepatomegaly, an accurate histological diagnosis being obtained in the majority. In patients with intra-abdominal malignancy, in whom surgery is planned, laparoscopy can detect disseminated disease and so avoid an unnecessary laparotomy. Laparoscopy may also provide a diagnosis in patients presenting with a variety of vague symptoms such as abdominal pain, weight loss, lethargy etc. We have found laparoscopy an excellent investigation if positive but, as if only allows the surface inspection of viscera, when negative, we recommend caution in its interpretation.

Comparison of colonic reservoir and straight colo-anal reconstruction after rectal excision.

The clinical and physiological results in 13 patients having a colonic J reservoir-anal anastomosis (CR) and 15 consecutive patients having a straight colo-anal reconstruction (SC) have been compared. The groups were matched for age, sex, level of tumour and proximal and distal resection margins. The incidence of postoperative complications was similar in each group. The mean follow-up in CR patients was 7 +/- 4 months and 47 +/- 23 months in SC patients. Stool frequency per 24 h was less than or equal to 2 in all CR patients while it was greater than 2 in 40 per cent of the SC patients (P less than 0.05). Three CR patients and six SC patients had minor incontinence, all but one of the rest were fully continent. One patient had a major leak. There was no significant difference in mean resting anal voluntary contraction pressure in the two groups, with mean values within the normal range. The mean rectal sensitivity threshold volume in CR patients (83 +/- 30 ml) and SC patients (52 +/- 22 ml) was significantly different (P less than 0.05) as was the mean maximum tolerable volume (317 +/- 122 ml and 174 +/- 83 ml respectively, P less than 0.01). There was no significant difference in balloon expulsion testing, defaecating proctography or methyl cellulose evacuation in the two groups. The addition of a colonic reservoir appears to avoid the high stool frequency occurring in some patients after straight colo-anal anastomosis.

Appendicectomy at cholecystectomy--an appraisal.

The effect of incidental appendicectomy in patients undergoing elective biliary surgery has been studied prospectively in 430 patients. In 236 patients the appendix was removed at the time of biliary surgery; in 194 patients the appendix was not removed or had already been removed at a previous operation. There was no significant difference between the two groups with regard to the incidence of septic complications--especially wound infection--more general complications, or in the mean post-operative stay in hospital. Histological examination of the macroscopically normal appendices revealed a surprising incidence of pathology (greater than 50 per cent). Provided the patient receives routine antibiotic prophylaxis, there appears to be a case for removing the appendix at the time of cholecystectomy if it is readily accessible.

Diagnostic lessons learnt from a series of enterovesical fistulae.

OBJECTIVE: An enterovesical fistula (EVF) is an uncommon condition requiring careful and sometimes extensive preoperative investigation. Our experience over a 10-year period has been reviewed with emphasis on the diagnostic investigations performed. PATIENTS AND METHOD: Forty-two patients (30 male) have been studied. Presenting symptoms, diagnostic investigations, and subsequent treatment have been reviewed. RESULTS: The site of the fistulae were; 37 colonic, 2 rectal, and 3 ileal. The commonest presenting symptoms were; pneumaturia 75%, faecaluria 63% and urinary tract infections 57%. The positivity rate of the investigations performed were; cystoscopy 89%, urine cytology 86%, barium enema 65%, computerized tomography (CT) scanning 55%, IVP 35%, and cystography 27.5%. The causes of the fistula were; diverticular disease 71%, carcinoma 20%, Crohn's disease 7%, and radiotherapy 2%. CONCLUSIONS: We recommend cystoscopy and urine cytology for faecal material as the first-line investigations in all patients with a suspected enterovesical fistulae. CT scanning and barium enema should not be first line investigations but may be performed subsequently to help determine the aetiology and planning of surgery.

'To bead or not to bead?'.

In subcuticular wound closure, the use of anchorage beads or knots to maintain opposition of wound edges is a common practice, but can lead to complications. One hundred and one abdominal subcuticular wound closures (44 vertical and 57 transverse) were prospectively studied and assessment of wound swelling was made by measuring the length of exposed suture at both ends of the wound, on successive days postoperatively. Results showed progressive reduction in the exposed suture length. We would suggest that if anchorage beads are used with subcuticular sutures then they should not be pulled tight as postoperative wound swelling will cause the beads to be drawn into the wound often resulting in a troublesome ulcer(s) at the end(s) of the wound.
