Endoscopic tattooing for colorectal lesions: impact on quality of care and patient outcomes.

INTRODUCTION: The National Bowel Cancer Screening Programme guidelines advocate the use of endoscopic tattooing for suspected malignant lesions to assist identification and to facilitate laparoscopic resections. However, endoscopic tattooing practices are variable in endoscopic units, resulting in repeat endoscopy and delay in patient management. The aim of this study was to assess the adherence to tattoo protocol for significant colonic lesions at an endoscopy unit in a large district general hospital. MATERIALS AND METHODS: Prospectively collected data were analysed for 252 patients with significant colonic lesions between January 2017 and December 2018. Data were collected through reviewing patient's notes, histopathology findings and endoscopy reports. Data on lesions, complications, number and site of tattoo placed, and any repeat endoscopy for a tattoo were collected. RESULTS: Of the 252 patients, 88% (n = 222) had malignant and 12% (n = 30) had benign lesions. Only 58.7% (n = 148) of those patients who had colonoscopy had tattoo placement reported. Of these 148 cases, the report stated the distance of tattoo in relation to the lesion in only 46% (n = 68) of patients. Unfortunately, 14.3% (n = 36) of patients required repeat endoscopy to tattoo the lesions prior to surgery. CONCLUSIONS: Our study highlights the lack of uniformity of tattoo practice among endoscopists. Despite the National Bowel Cancer Screening Programme guidelines, a significant proportion of colorectal lesions are still not tattooed during their first endoscopy. Some patients had to have repeat endoscopy just for the purpose of tattooing. Active involvement and participation of all endoscopists in the colorectal and the complex polyp multidisciplinary teams may help to improve the tattoo service.

'How compliant do we want to be with the colonoscopy surveillance guidelines?'.

OBJECTIVE: To assess the referral practice for surveillance colonoscopy amongst clinicians and to measure whether practice was inline with the current Association of Coloproctology of Great Britain and Ireland (ACPGBI) and the British Society of Gastroenterology (BSG) guidelines. METHOD: A questionnaire was sent to members of the ACPGBI. RESULTS: A total of 195 (49%) clinicians responded, providing information on their referral habits with comments on where they deviated from the guidelines. CONCLUSIONS: The BSG and ACPGBI guidelines are well established amongst clinicians and generally accepted as best practice, however, the majority of clinicians deviate from the guidelines for particular clinical scenarios. In fact only 18% of respondents followed all recommendations for surveillance colonoscopy for patients with polyps, previous cancers and a family history.

Why wait for a colonoscopy? An easy cure.

OBJECTIVE: Three thousand five hundred and forty-nine patients are waiting for a colonoscopy in the Kent and Medway cancer network. New guidelines identify those who require surveillance for polyp, cancer, IBD and family history. Our hypothesis was that most of the patients on the waiting list would no longer need a colonoscopy if the new guidelines were applied. PATIENTS AND METHODS: We compared the ACPGBI guidelines for screening/surveillance colonoscopy with the indications in 411 notes of one hospital's waiting list and removed patients as appropriate. In the second part of study we analysed 192 patients attending colonoscopy in seven hospitals in the region and calculated the potential impact of the guidelines on our waiting lists. RESULTS: Of 411 patients on the waiting list in one hospital, only 98 (24%) needed to remain on the list. 142 (34%) were cancelled completely. One hundred and seventy-one (42%) were taken off the 'waiting' list and rebooked for a later date since according to the new guidelines the colonoscopy was not due yet. Of 192 colonoscopies actually performed during the study period in 7 hospitals of Kent and Medway cancer network, 72 (38%) were for surveillance. Two thirds of those were not in line with the guidelines. As a result of implementing the guidelines, waiting times for diagnostic colonoscopy fell from 12 to 4 weeks for urgent, and from 40 to 15 weeks for routine referrals. CONCLUSION: A quarter of the 8000 colonoscopies performed annually in our region are unnecessary when compared to the guidelines. More than three quarters of our waiting list could be removed by reviewing the notes. Implementing the guidelines in one cancer network would save pounds 1 million per year even on conservative estimates of pounds 500 per colonoscopy. It would also reduce the waiting times for diagnostic colonoscopy.

Natural history of the ectatic aorta.

OBJECTIVES: To define the natural history of ectatic abdominal aortas and to assess the clinical need for follow-up. DESIGN: Abdominal aortas were considered ectatic if they were diffusely and irregularly dilated with a diameter less than 3 cm. Ectatic aortas were identified either by AAA screening or as incidental findings. Patients who had only one scan were excluded from the study. Clinical data were analysed. SETTING: Two district general hospitals in Wales and England. SUBJECTS: 116 patients (90 men). RESULTS: : The median age of patients was 71 years (range 48-90). Co-existing risk factors included hypertension (75), IHD (22), PVD (8), diabetes (3), COAD (14), stroke (5), popliteal aneurysm (1), malignant disease (3) and 4 had a family history of AAA. The median follow-up was 24 months (range 5-72). The median and maximum growth rate of the ectatic aortas were 0.65 and 14.4 mm/year respectively. In three patients the expansion rate was more than 5 mm/year. In 22 patients the ectatic aorta became aneurysmal, reaching a diameter greater than 3 cm. There were no ruptures and no elective repairs. Two deaths occurred due to IHD. CONCLUSIONS: : This study demonstrates that if ectatic aortas do expand they do so very slowly. However, 22 of the 116 (19%) became aneurysmal in a follow-up of two years. Once identified ectatic aortas should be scanned at intervals of three years.

Review of surgical management of aldosterone secreting tumours of the adrenal cortex.

AIMS: To evaluate the investigation and surgical management of primary hyperaldosteronism. Retrospective case note analysis of thirty-three patients who underwent adrenalectomy for primary hyperaldosteronism between 1982 and 2001 and a current relevant literature review. METHODS: The records of twelve male and twenty-one female patients, age range 18 to 81 (mean 48 years) were reviewed. Eleven operations were performed by an open approach and twenty-two laparoscopically. Preoperative investigations included computed tomography (CT), magnetic resonance imaging (MRI), selective venous sampling and seleno-cholesterol isotope scanning, along with biochemical and hormonal assays. Twenty-six benign adenomas, three nodular hyperplastic lesions, one primary adrenal hyperplasia and three functional carcinomas were excised. Mean follow up was 12 months. RESULTS: Patients had a mean blood pressure of 185/107 mmHg for 6.2 years mean duration. The mean severity of hypokalaemia was 2.7 mmol/l. Sensitivity of CT scanning was 85%, and of MRI 86%. Fifty percent of seleno-cholesterol scans were accurate. Mean operating time was 158 min for laparoscopic adrenalectomy whilst open surgery took 129 min (p=0.2, NS). Two cases commenced laparoscopically required open access for control of primary haemorrhage whilst one other bleed was managed via the operating ports. Mean postoperative stay was significantly shorter for the laparoscopic group (3 days compared with 7.9 days, p<0.0001). Thirty day mortality was zero. There were three infective complications in the open group (two chest, one wound) with no postoperative complications in the laparoscopic group. All patients were cured of hypokalaemia, whilst 62% cure of hypertension was achieved. Of those patients whose blood pressure was improved preoperatively by spironolactone 78% were cured by adrenalectomy. Adrenalectomy led to an overall reduction in the mean number of anti-hypertensive medications (2.3 drugs preoperative to 0.6 postoperative, p<0.0001). Of those not cured, 58% had improved blood pressure control requiring less medication on average (1.6 drugs compared with 2.6 drugs, p=0.08). Mean age of patients not cured by surgery was 55 years, whilst those cured was 44 years (p=0.03). CONCLUSIONS: Primary hyperaldosteronism is a rare but important cause of hypertension. Selective venous sampling is a useful tool where investigations are inconclusive and fail to lateralise secretion. Patients with primary hyperaldosteronism enjoy lower complication rates and earlier discharge with the advent of laparoscopic surgery. Most patients will be cured of their hypertension and all of hypokalaemia. Laparoscopic adrenalectomy is now the accepted method of surgery for benign hyperaldosteronism. Those with bilateral disease due to idiopathic hyperaldosteronism (IHA) are not candidates for surgery and should be treated medically.

Nurse-led direct access endoscopy clinics: the future?

BACKGROUND: Many studies have shown that rectal bleeding is a good indicator of underlying colorectal pathology, and that ost of the lesions in patients presenting with rectal bleeding lie in the left side of the colon [1, 5, 9, 12, 23, 26]. The recent acceptance of the nurse-practitioner by the National Health Service may allow the use of nurse-endoscopists to develop throughout the United Kingdom. This study aimed to audit a unique nurse-led direct-access nurse-endoscopy service with regard to its efficacy and cost effectiveness, and to monitor patient satisfaction and direct referrals from the primary health sector. METHODS: A nurse-led open-access flexible sigmoidoscopy (OAFS) service for patients reporting fresh rectal bleeding was established at our center in February 1996. A prospective audit of sigmoidoscopic findings and a retrospective analysis of referral patterns from local general practitioners were conducted. A questionnaire survey of both patient and general practitioner satisfaction also was conducted at the same time. RESULTS: Since February 1996, 706 patients have been referred to our service. Rectal bleeding was by far the most common cause for referral, representing the dominant symptom in 92% of the referrals received. Although 99% of the patients underwent a complete sigmoidoscopic examination, 16% of these examinations were limited because of several factors combined. A cause for bleeding was identified in 91% of the patients, with 24% of them experiencing subsequent significant pathology. Of the patients surveyed, 99% were satisfied with the service provided. The results also show nurse-led OAFS to be a more effective use of financial resources, costing $90 less per patient than general practitioner referrals sent to a consultant for further action. CONCLUSIONS: Rectal bleeding is a good indicator of underlying colorectal disease. Most of the significant lesions presenting with this symptom are found in the left side of the colon. A nurse-led OAFS is safe, effective, and acceptable to patients. It also is more cost effective than a consultant-led service.

Splenogonadal fusion: report of a rare variety.

We report an unusual case of splenogonal fusion in a 10-year-old boy with an undescended left testis. He suffered from congenital limb defects, a known association with splenogonadal fusion, and had originally been admitted for orchidopexy.

Smoking--do vascular surgeons practise what they preach?

Smoking is a major health problem in Great Britain and cigarette consumption is rising. Although there are studies concerning the smoking habits of hospital physicians, nurses and oral and maxillofacial surgeons, little is known about the smoking habits of vascular surgeons and the advice given by them to their patients. A questionnaire survey was conducted involving 422 members of the Vascular Surgical Society of Great Britain and Ireland. The response rate was 74%. The median age of responders was 51 years (range, 32-69 years) of whom 98% were men. Of responders, 98% routinely advise patients to stop smoking, 10% advise nicotine gum/patch, 39% provide antismoking information sheets, 11% are involved in an antismoking clinic/group and 74% check to see whether patients continue to smoke. The majority of responders would be prepared to offer revascularisation in patients who continue to smoke. Only 8 surgeons (3%) would not advise revascularisation in this group of patients. Only 10% of respondents were current smokers, 37% were ex-smokers and 53% had never smoked. Vascular surgeons, therefore, seem to practise what they preach.

The nurse practitioner endoscopist.

Most upper and lower gastrointestinal endoscopies in Great Britain and Ireland are performed by surgeons, physicians or radiologists. Since the introduction of the 'nurse endoscopist' by the British Society of Gastroenterology Working Party, few centres in the UK have adopted this policy. We have reviewed the anxiety about nurse practitioner endoscopists among patients and physicians. Finally, the role and future of the nurse practitioner endoscopist in the UK is discussed.

Mortality from ruptured abdominal aortic aneurysm in Wales.

BACKGROUND: The aim of this study was to identify the incidence of, and mortality in, patients with a ruptured abdominal aortic aneurysm (AAA) reaching hospital alive in Wales. METHODS: Patients who presented with a ruptured AAA between September 1996 and August 1997 were analysed. Data were collected prospectively by an independent body, observing strict confidentiality. RESULTS: Some 233 patients with a confirmed ruptured AAA were identified, giving an incidence of eight per 100 000 total population. Some 133 patients (57 per cent) underwent attempted operative repair; 85 (64 per cent) of these died within 30 days. Of the 233 patients, 92 were admitted under the care of a vascular surgeon and 141 under a non-vascular surgeon. Vascular surgeons operated on 82 patients (89 per cent), of whom 50 (61 per cent) died, whereas non-vascular surgeons operated on 51 patients (36 per cent), of whom 35 (69 per cent) died. DISCUSSION: This study is unique as it is an independent prospective study of mortality in patients with a ruptured AAA who reached hospital alive. Mortality was independent of the operating surgeon, but vascular surgeons turned down significantly fewer patients than non-vascular surgeons (11 versus 64 per cent, P < 0.001).
