Are we overusing ultrasound in non-traumatic acute abdominal pain?

BACKGROUND: Ultrasound is being used increasingly in the assessment of acute non-traumatic abdominal pain as it is non-invasive and does not carry the risk of radiation. However, the inappropriate use of ultrasound can lead to a delayed or incorrect diagnosis, more work for the personnel involved, and increased hospital costs. METHODS: A prospective study was conducted to analyse the clinical indications for requesting an ultrasound in those admitted to a district general hospital with acute non-traumatic abdominal pain, and to assess whether there is a correlation between clinical and laboratory findings and ultrasound results. A total of 110 patients were studied during a three month period. RESULTS: The results suggest that ultrasound is useful in the investigation of suspected biliary colic and abdominal masses. However, the yield of ultrasound in other patients with acute non-traumatic abdominal pain is low. This study also suggests that the yield of "positive" reports on ultrasound is significantly higher in patients with localised abdominal pain and tenderness and in those with acute abdominal pain and a raised white cell count or raised liver function tests. The yield of positive reports in patients with acute abdominal pain was found to be lower those less than 25 years of age than in older patients.

Fluid and electrolyte balance: how do junior doctors measure up?

Fluid and electrolyte disorders are common in hospital patients and can cause serious complications, especially in the elderly. The task of fluid management is often left to the most junior members of the team, the senior house officer and the preregistration house officer. However, the level of teaching and support available to them in this regard appears to be unsatisfactory.

The effectiveness of new criteria for colorectal fast track clinics.

INTRODUCTION: Fast Track Colorectal Clinics are becoming a requirement to meet the government's 10-day rule for patients with suspected cancers to be seen by a specialist. However, such clinics soon tend to get overwhelmed by huge numbers of referrals, many of them inappropriate. The Association of Coloproctology of Great Britain and Ireland has published criteria for appropriate referral. We evaluated the sensitivity of these criteria and attempted to recommend appropriate changes. METHODS: Data of 50 consecutive colorectal cancers from our DGH since January 2000 has been collected in relation to demographics, presenting signs and symptoms, haemoglobin levels as well as treatment. The new Criteria were then applied strictly to these cases and we evaluated whether these patients would have been eligible for fast track referral, if these criteria had been in force since January 2000. RESULTS: Forty-one (82%) of 50 patients would have been eligible for referral as follows: 11 (22%) rectal bleeding with diarrhoea; 8(16%) persistent diarrhoea without bleeding (>60 years), 12 (24%) bleeding without anal symptoms (>60 years), 0 (0%) palpable right sided abdominal mass, 7 (14%) palpable rectal mass, 16 (32%) iron deficiency anaemia (<11 g/dl in men & <10 g/dl in women), 10 (20%) patients qualifying on more than one criterion. However, 9 (18%) patients had presenting features that would have excluded them from a fast track referral as follows: 4 (8%) only abdominal pain + weight loss (48, 54, 72, 75 years old), 2 (4%) change in bowel habit + no rectal bleeding (54, 57 years old), 1 (2%) palpable mass at a site other than the right side of the abdomen. CONCLUSIONS: We feel that this study, although small, highlights the dangers of having very rigid criteria for such clinics. The new criteria though high in specificity have low sensitivity for safety. We recommend some modifications to the criteria as follows: rectal bleeding without anal symptoms >50 years instead of 60 years; patients with a palpable mass anywhere on the abdomen; and the adddition of a new criterion of abdominal pain with weight loss. These modifications would significantly increase the sensitivity from 82% to 94%.

Costs of waiting for gall bladder surgery.

Laparoscopic cholecystectomy is one of the most commonly awaited general surgical procedures in the UK. However, many patients awaiting a cholecystectomy are admitted with recurrent gallstone related symptoms while on the waiting list, resulting in significant morbidity. The aim of this study was to quantify this problem, and also to analyse the cost implications of these admissions for the NHS. A retrospective study was performed of all patients who underwent an elective cholecystectomy by three consultants in a district general hospital between January 1999 and January 2000. The demographic details, indications for surgery, details of the emergency admissions while on the waiting list, and the treatment given during these episodes were recorded. One hundred and fifty six patients were included in the study, of which 122 (78%) were females. The mean (SD) age of the patients was 54 (5) years. The mean waiting time for surgery in these patients was 12 (3) months. Thirty seven patients (23.7%) were admitted as an emergency due to gallstone related symptoms and complications while awaiting surgery. There were 47 episodes of admissions in total, of which 32 were for biliary colic, 13 were for acute cholecystitis, and two were for acute pancreatitis. In addition to routine blood tests, 20 abdominal radiographs, 10 chest radiographs, three endoscopic retrograde cholangiopancreatography tests, five ultrasonograms, and one computed tomogram were carried out in these patients. The mean duration of each episode of admission was three days. The cost of treatment per episode was pound 946 and the total cost of treating the 37 patients was calculated to be pound 44 462. Performing early laparoscopic cholecystectomy for acute cholecystitis may help to reduce costs by preventing recurrent emergency admissions in these patients. Further studies to identify risk factors associated with recurrent symptoms and complications in patients with gallstone disease may help to prioritize them for early surgery.

The natural history diverticular disease: is there a role for elective colectomy?

BACKGROUND: The natural history of colonic diverticular disease is unclear leading to a debate on the value of elective colectomy in preventing complications of the disease. AIM: To assess whether the complications of diverticular disease requiring emergency surgery are related to previous episodes of diverticulitis and whether elective colectomy might prevent such complications. MATERIALS AND METHODS: A retrospective study was done on all patients admitted with complicated diverticular disease in two adjacent district general hospitals between 1995 and 2000. Information was collected on the details of management of the complications and past history of the investigations and treatment for diverticular disease in these patients. RESULTS: A total of 108 patients were admitted with complicated diverticular disease. Ninety eight (91%) patients were admitted as an emergency for perforated diverticular disease and rectal bleeding. Ten patients were urgent admissions for fistulae and diverticular phlegmons. Ninety eight patients underwent a Hartmann's operation, two had a subtotal colectomy and 4 patients had a sigmoid colectomy. Thirty four (31.4%) patients died in hospital post-operatively. Of the 108 patients, only 28 (26%) patients were known to have diverticular disease previously. Only three (2.7%) patients had had an episode of acute diverticulitis before they presented with further complications. CONCLUSIONS: Complications of diverticular disease occur de novo in the majority of patients who have no previous history of the disease. Further studies are needed to identify risk factors for complicated diverticular disease before adopting a policy of elective interval colectomy.
