Appendicectomy deferred to a CEPOD list: the patients' opinion

AIMS

Implementation of NCEPOD guidelines to avoid out-of-hours operating, Junior doctors' 'New Deal' and EWTD have significantly altered surgical practice. Patients admitted 'out of hours', who need an emergency procedure, are often deferred until the next day. We have attempted to assess patients' opinions of this management plan.

METHODS

Consecutive patients admitted with uncomplicated appendicitis and operation deferred to the next day according to NCEPOD guidelines were studied. A surgeon, other than the one carrying out the initial assessment, performed the operation on a scheduled morning emergency list. A full explanation was given to patients regarding reasons for deferring operation, and they found out that a different surgeon would be performing their operation. Patients completed a questionnaire post-operatively.

RESULTS

42 patients were studied; median age 24 years (range 17-69); 32 men, 10 women. Thirty presented after 6 p.m. and eight after midnight. The remaining four were admitted during the day. Only one third of the patients recalled reasons for deferred operation with seven not remembering being given an explanation. Two thirds (n=27) of the patients slept poorly pre-operatively, principally due to pain (17) and ward noise (10). Operation on the same night as their admission was the preferred option in 24 patients. All of these slept poorly. Some 22 patients would have preferred the admitting surgeon to have performed their operation; 16 expressed no preference. Only four patients preferred a 'new' surgeon the following day. Of the 42 patients, 28 did not know who had performed their operation.

CONCLUSION

Despite being told why their operation was delayed most patients would prefer not to have their procedure delayed. Lack of sleep pre-operatively is a major determinant of patient opinion. Few patients wanted a 'new' surgeon to perform their operation.

The acute blue finger: management and outcome

INTRODUCTION

The objective was to assess the management, and short- and longer-term outcome of patients presenting with an acute blue finger.

PATIENTS AND METHODS

This was a retrospective, case-note review and prospective follow-up by telephone and general practitioner enquiry. All patients who presented with sudden onset blue discolouration of a finger within the previous 72 h, with normal radial and ulnar pulses, were included.

RESULTS

From 2000 to 2006, 22 patients, 15 female, 7 male, were reviewed. Median age was 56 years (range, 19-88 years). Median time from onset of blue finger was 6 days (range 1 day to 3 months). In most cases (17), no underlying cause was identified. Five patients had an underlying cause; two had symptoms compatible with Raynaud's phenomenon, one patient had signs (later confirmed on MRA) of arterial thoracic outlet syndrome and two had polycythaemia (haemoglobin > 17 g/dl). Otherwise, all laboratory investigations were normal. Upper limb duplex, echocardiogram and 24-h cardiac tapes were normal in all cases. Median follow-up was 19 months. Three patients had recurrent symptoms in the finger. No patient suffered tissue loss or loss of digit(s), and none had stroke or arterial embolisation.

CONCLUSIONS

The acute blue finger is a benign condition not suggestive of arterial embolisation. Tissue or digit loss is not a threat and, in the longer term, there is no threat of embolisation to other vascular sites.

Tract-based spatial statistics of diffusion tensor imaging in adults with dyslexia

BACKGROUND AND PURPOSE

Diffusion tensor imaging is a tool that can be used to study white matter microstructure in dyslexia. We tested the hypothesis that dyslexics have a white matter structural change (as measured by directional diffusion of water, which can be affected by disruption in white matter tracts) between brain regions that previous functional connectivity studies showed were associated with phonologic processing.

MATERIALS AND METHODS

Diffusion tensor imaging (DTI) scans were acquired from 7 healthy adult normal readers and from 14 adults with dyslexia on a 1.5T scanner. Voxelwise statistical analysis of the fractional anisotropy data were carried out by using Tract-Based Spatial Statistics to compare dyslexic subjects versus control subjects in white matter tracts.

RESULTS

Significant group difference map clusters (comparing adults with and without dyslexia) occurred in specific bilateral white matter tracts within the frontal lobe, temporal lobe, occipital lobe, and parietal lobe.

CONCLUSION

The DTI fractional anisotropy results in the bilateral white matter showing higher fractional anisotropy in adult control subjects compared with adults with dyslexia (relating to white matter fiber tract integrity) are consistent with our previous functional connectivity results from seed points in the bilateral inferior frontal gyrus.

Fast Track Open Aortic Surgery: Reduced Post Operative Stay with a Goal Directed Pathway

OBJECTIVE

Open aortic aneurysm repair is traditionally associated with an extended hospital stay. The aim of this study was to examine the feasibility of reducing post-operative stay through the implementation of a fast-track, goal directed, clinical pathway for elective open aortic surgery.

METHODS

A fast-track clinical pathway for aortic surgery was introduced in a regional vascular unit in September 2005. The pathway has daily goals and targets discharge for all patients on the 3rd post operative day. This study compares thirty consecutive discharges of unselected patients undergoing elective infra-renal aortic surgery following introduction of the pathway to the thirty consecutive cases preceding its introduction. Reasons for prolonged hospital stay were recorded.

RESULTS

Six of thirty patients achieved discharge by Day 3. The median hospital stay reduced from 9 (range 4 to 17 days) to 5 days (range 2 to 12 days) following introduction of the pathway. There was one readmission within 30 days and no complications attributable to the pathway implementation. Cardiac complications and home planning were the most common causes of delayed discharge.

CONCLUSION

Post-operative stay in patients undergoing standard elective open infra-renal aortic surgery can be safely reduced with the introduction of a goal directed pathway.

Supervised Exercise Training for Intermittent Claudication: Lasting Benefit at Three Years

OBJECTIVES

To assess the long-term outcome of supervised exercise training for intermittent claudication.

METHODS

A prospective study was undertaken of all patients referred to a single centre with intermittent claudication (>46 m). Patients underwent supervised exercise training twice weekly for 10 weeks, with regular follow-up to 3 years. Actual Claudication Distance (ACD), Maximum Walking Distance (MWD) and ankle-brachial pressure indices (ABPI) were measured.

RESULTS

In 202 patients the initial median ACD and MWD were 112 m and 197 m. Following exercise therapy both the median ACD and MWD increased to 266 m and 477 m at three months, increases of 237% and 242% respectively (p<0.001). At three years the median ACD and MWD were 250 m and 372 m, increases of 223% and 188% respectively (p<0.001). There was no significant change in ACD or MWD at 3 months compared to 1, 2 or 3 years. ABPI remained unchanged throughout.

CONCLUSIONS

Supervised exercise training has long term benefit in patients with intermittent claudication. Results seen at 12 weeks are sustained at three years.

Thrombin injection for acute hemorrhage following angiography

Femoral arterial puncture is the main access for diagnostic and therapeutic intervention in vascular disease. Significant complications are unusual and include uncontrolled bleeding which usually requires surgery. We report the use of ultrasound-guided thrombin injection that prevented any immediate need for surgery in 2 cases of uncontrolled bleeding following femoral arteriography. Clinical presentations and treatment are reported, together with a review of the literature.

Nipple discharge: a sign of breast cancer?

INTRODUCTION

Nipple discharge is regarded a sign of breast cancer. Type of discharge and cytology are unreliable for diagnosis. Most malignant cases have a detectable breast mass. The aim of this study was to assess the association between nipple discharge and breast cancer.

PATIENTS AND METHODS

Patients who underwent operation for nipple discharge at a district general hospital (population 460,000) over a 3-year period were included. All had normal clinical, radiological and cytological examination. Operation and histopathology reports were reviewed.

RESULTS

Eighty-six patients underwent operation for nipple discharge. Median age was 54 years (range, 32-84 years). Analysis of nipple discharge revealed red blood cells (RBCs) in 35 patients (40%). At operation, 81 patients underwent radical sub-areola duct excision (Hadfield's procedure) and five microdochectomy. Histopathology reported duct ectasia in 59 patients and benign ductal papilloma in 25. Two patients had occult malignancy - DCIS (1) and LCIS (1). No invasive cancer was found.

CONCLUSIONS

Nipple discharge alone is not usually a sign of breast cancer. Occult malignancy is rare. A period of 'watchful waiting' may prevent patients undergoing unnecessary surgery.

Vascular surgical emergencies: how will future surgeons be trained?

INTRODUCTION

We wished to assess whether pattern and impact of emergency vascular surgical referrals has altered since a previous study in 1990. Following introduction of shift working patterns, we wished to assess how these changes may affect vascular training and vascular on-call cover.

PATIENTS AND METHODS

Prospective survey of emergency vascular referrals at two district general hospitals (DGH-R and DGH-L) in 2003. DGH-R received only regional referrals whereas DGH-L also received 'next day' referrals from a smaller hospital. Results were compared between centres and with a previous study undertaken at DGH-R in 1990.

RESULTS

From 1990 to 2003 emergency vascular referrals at DGH-R increased by 51% (53 to 80). The number seen at DGH-R and DGH-L were similar in 2003. There were significantly more out-of-hours referrals in DGH-R than DGH-L (59% versus 35%; P = 0.0123). Referrals were more likely to be seen initially by the vascular team at DGH-L than DGH-R (80% versus 47%, P < 0.0001).

CONCLUSIONS

Vascular emergency referrals have increased. A trainee was likely to see more emergency referrals at DGH-L than DGH-R. This may impact on future training.

Effects of a thyroid-stimulating human monoclonal autoantibody (M22) on functional activity of LH and FSH receptors

OBJECTIVE

The glycoprotein hormones luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyrotropin (TSH) show low-level cross-reactivity between their respective receptors (R). Patient serum autoantibodies to the thyrotropin receptor (TSHR) do not appear to cross-react with the luteinizing hormone receptor (LHR) or follicle-stimulating hormone receptor (FSHR), although the concentrations of autoantibody with which it is feasible to carry out experiments of this type are limited. Consequently, we have studied the effects of high doses of the thyroid-stimulating human monoclonal autoantibody (M22) on the LHR and FSHR.

DESIGN

Chinese Hamster ovary (CHO) cells stably expressing the TSHR, LHR, and FSHR and purified M22 IgG preparations were used in the study.

METHODS

CHO-TSHR, CHO-LHR, and CHO-FSHR cells were incubated with bovine TSH (0.1-25mU/mL), human recombinant chorionic gonadotropin (hCG; 0.5-10mU/mL) or human recombinant FSH (100-5000mU/mL) or with M22 IgG (0.001-5.0 microg/mL), and the extracellular cyclic AMP was measured by radioimmunoassay.

RESULTS

Cyclic AMP levels increased in a dose-dependent manner after incubation of CHO-TSHR cells with TSH or M22 IgG, and on a molar basis the effects of TSH and M22 were similar. Cyclic AMP stimulation was not detectable in CHO-LHR and CHO-FSHR cells after incubation with M22 IgG, whereas incubation with hCG or FSH, respectively, caused dose-dependent cyclic AMP stimulation. On a molar basis, concentrations of M22 IgG approximately 100x those of FSH causing clear stimulation were ineffective with CHO-FSHR cells. Similarly, molar concentration of M22 IgG 20,000x those of hCG causing clear stimulation had no effect on CHO-LHR cells.

CONCLUSIONS

This study shows that at relatively high concentrations, M22 IgG is unable to stimulate cyclic AMP levels in CHO-LHR or CHO-FSHR cells, suggesting that TSHR autoantibodies have greater specificity for the TSHR than TSH itself.

Duplex-defined spatial anatomy of the saphenopopliteal junction

Background: Failure to disconnect the saphenopopliteal junction (SPJ) can occur in spite of duplex marking prior to operation indicating that more information on the short saphenous vein (SSV) termination in addition to the duplex mark is necessary to improve operative outcomes. The aim of this study was to establish the three-dimensional anatomy of the SSV termination to aid in improving operative localization of the SSV and SPJ.

Method: A prospective colour duplex study of 50 consecutive primary refluxing SSV was undertaken. The spatial orientation of the SSV termination in terms of location within the popliteal fossa and depth from the skin was determined.

Results: The SPJ was located in most cases (98%) in the upper lateral quadrant of the popliteal fossa. The median depth of the SPJ beneath the skin was 2.9 (1.6–5.2) cm. The SSV leaves the midline at a distance of approximately 5 (0–8) cm below the midpoint of the popliteal fossa and travels laterally towards the SPJ. It stays close to the skin and makes the descent into the fossa at 2–3 cm below the SPJ. The mean rate of descent between the SPJ and 2 cm below it was 7.0 (1–12) mm/cm, while that between 2 and 4 cm below the SPJ was only 2.3 (0–7) mm/cm.

Conclusion: The SPJ lies at a variable depth beneath the skin in the upper outer quadrant of the popliteal fossa. Locating the incision 2 cm below and medial to the SPJ, where the SSV lies relatively superficial and at a less variable depth, will allow easier identification of the SSV and thus easier localization of the SPJ.
