Retrograde intussusception through a loop ileostomy: a case report and review of the literature.

Intussusception through loop ileostomy is rare and must be treated without delay to avoid further complications. Retrograde intussusception is even rarer. We report a case of small bowel obstruction caused by retrograde intussusception through the distal limb of loop ileostomy in a male patient. A literature search is also carried out regarding this entity and published reports are discussed.

Follow up of patients with colorectal polyps: are the BSG guidelines being adhered to?

OBJECTIVE: The publication of the BSG guidelines in 2002 provided a framework for the follow up of patients with colorectal polyps. The aim of the present study was to determine whether they had, or were being correctly adhered to in a moderately sized District General Hospital. METHOD: A total of 598 patients were on the waiting list for colonoscopy at Airedale General Hospital (AGH) in February 2005. Of these, 203 were being followed up as a result of the previous finding of a polyp. RESULTS: Only 14.8% of patients had been or were being followed up according to the BSG guidelines. The majority of the 85.2% of patients who did not comply with follow up did so as a result of over investigation. Seventy-eight per cent of the low-risk group and 55% of the intermediate-risk group had been colonoscoped, or were waiting to have colonoscopy, too soon or too frequently according to the BSG guidelines. Twenty-four patients with hyperplastic polyps were being followed up incorrectly, as were 17 patients discovered to have a polyp pathology on flexible sigmoidoscopy. It was established that 131 extra colonoscopies had been, or were planned to be performed unnecessarily. CONCLUSION: These data have major implications with regard to patient safety, service provision and cost to the NHS.

Small bowel obstruction due to inflammation secondary to ingested bone.

We report the CT appearances of an ingested pork bone in the lumen of small bowel in a 66-year-old man with an intact and virgin gastrointestinal tract. CT scan demonstrated the site of obstruction at distal jejunum with associated irregular narrowing and proximal small bowel dilatation as well as the bone lodged in the non-dilated terminal ileum. Laparotomy and histology of the resected small bowel confirmed the CT appearances that the obstruction was caused by adhesions and extensive inflammation across the bowel wall in the distal jejunum from trauma as the bone traversed down the lumen. We believe that this is the first reported preoperative CT scan finding of a case of small bowel obstruction due to adhesions and inflammation secondary to ingested bone.

Direct Access Minor Surgery service--patient satisfaction and effectiveness.

INTRODUCTION: Waiting lists for surgical out-patients and elective operations are a major concern of the National Health Service. A Direct Access Minor Surgery programme in an ambulatory minor theatre area has been introduced to expedite patient treatment. The response of patients to this service has been assessed. PATIENTS AND METHODS: A postal questionnaire was offered to all patients attending for the Direct Access Minor Surgery over a period of 20 months (January 2002 to August 2003). Patients were asked about direct attendance for surgery without a prior out-patient appointment, about waiting time before operation on the day of surgery and the adequacy of pre-operative information. Overall satisfaction was assessed using a scoring system. The incidence of inappropriate referrals was analysed. The influence of the service on waiting lists and resources was assessed. RESULTS: A total of 221 patients were operated on, 257 lesions being excised. Response rate to the postal questionnaire was 55%. Of respondents, 75% thought that it was appropriate to attend the hospital directly without an out-patient clinic appointment. To 83% the waiting time was acceptable. Of patients, 90% were happy with the pre-operative information. Overall, 91% of respondents were very satisfied with the service. Inappropriate referrals were 4%. The new service reduced waiting time for minor surgery from 53 to 10 weeks. It also released approximately 140 new out-patient slots per annum. CONCLUSION: Direct Access Minor Surgery is a safe and favoured service with high patient satisfaction.

A double stapled technique for oesophago-enteric anastomosis.

AIM: Leakage from oesophageal anastomosis is associated with substantial morbidity and mortality. This study presented a novel, safe and effective double stapled technique for oesophago-enteric anastomosis. METHODS: The data were obtained prospectively from hospital held clinical database. Thirty nine patients (26 males, 13 females) underwent upper-gastrointestinal resection between 1996 and 2000 for carcinoma (n = 36), gastric lymphoma (n = 1), and benign pathology (n = 2). Double stapled oesophago-enteric anastomosis was performed in all cases. RESULTS: No anastomotic leak was reported. In cases of malignancy, the resected margins were free of neoplasm. Three deaths occurred, which were not related to anastomotic complications. CONCLUSION: Even though the reported study is an uncontrolled one, the technique described is reliable, and effective for oesophago-enteric anastomosis.

A multi-centre study to compare meropenem and cefotaxime and metronidazole in the treatment of hospitalized patients with serious infections.

We conducted a prospective, multi-centre, open, randomized study in 11 UK hospitals to compare iv meropenem 1 g tds with the combination of iv cefotaxime 1 g tds and iv metronidazole 500 mg tds in patients with serious infections. One hundred and sixty-one patients were enrolled, of whom 131 were clinically evaluable (meropenem, n = 68; cefotaxime/metronidazole, n = 63). The most common infections were subsequent to intra-abdominal pathology (meropenem, n = 77%; cefotaxime/metronidazole, n = 75%), and were usually accompanied by septicaemia (meropenem, n = 61%; cefotaxime/metronidazole, n = 53%). The incidence of a satisfactory clinical response was similar in the two groups at the end of treatment (93% for meropenem; 92% for cefotaxime/metronidazole) and up to 8 weeks later (96% for meropenem; 93% for cefotaxime/metronidazole). Satisfactory bacteriological response (success or presumed success) was recorded at the end of therapy in 86% of meropenem and 88% of cefotaxime/metronidazole patients. Adverse events were reported in 32% of meropenem and 25% of cefotaxime/metronidazole patients, and most were mild or moderate and did not require discontinuation of therapy. Twenty-one patients (ten meropenem and 11 cefotaxime/metronidazole) died during the trial, underlining the severity of the infections being treated in this group of patients. None of the deaths was thought to be related to study therapy.

Oesophageal leiomyoma--a rare cause of reflux oesophagitis.

Reflux oesophagitis is a common condition encompassing a spectrum of symptoms. We report an apparently novel cause of this condition, and highlight possible symptomatology that may be suggestive in its pre-operative diagnosis.

Bile reflux and intestinal metaplasia in gastric mucosa.

AIM: To determine associations between enterogastric bile reflux and gastric mucosal pathology. METHOD: A retrospective study using fasting gastric juice bile acid measurements and antral or prestomal biopsy specimens from 350 patients, 66 of whom had previously undergone surgery that either bypassed or disrupted the pyloric sphincter. RESULTS: Bile reflux was positively associated with reactive gastritis and negatively with Helicobacter pylori density. After stratification for previous surgery, age, and H pylori status, the histological feature most strongly associated with bile reflux was intestinal metaplasia, including all its subtypes. The prevalence of intestinal metaplasia was greatest in patients with both H pylori infection and high bile acid concentrations. Bile reflux was also positively associated with the severity of glandular atrophy, chronic inflammation, lamina propria oedema and foveolar hyperplasia. CONCLUSIONS: Bile reflux is a cause of reactive gastritis. It modifies the features of H pylori associated chronic gastritis. The changes are not confined to patients who have had surgery to their stomachs. The positive associations with atrophy and intestinal metaplasia have implications for models of gastric carcinogenesis.

Primary Casualty Reception Ship: the hospital within--Operation Granby.

As the build-up of Operation Granby forces developed in the Gulf, casualty estimates indicated the need for a 100-bed hospital facility to care for the possible maritime casualties. RFA Argus, the Air Training Ship, was identified as the potential Primary Casualty Reception Ship (PCRS) and at the end of September 1990 plans were drawn up to convert the forward hangar into a two-storey 100-bed hospital in collective protection (COLPRO). In the three weeks prior to deployment, the hospital was designed, built, equipped and staffed. Argus arrived in the Gulf in mid-November as the PCRS with, all in COLPRO, a 10-bed intensive care unit (ICU), a 14-bed high dependency unit (HDU), a 76-bed low dependency unit (LDU) plus four operating tables in two theatres with full support services. The hospital was staffed by a medical team of 136 personnel and supported by the Air department with four casualty evacuation helicopters, an RN Party and the staff of the RFA. One hundred and five patients were treated of which 78 were returned to duty. Argu as PCRS spent longer in the northern Persian Gulf than any other ship, UK or US.

Operating at sea in an aircraft carrier.

The policy of the Medical Officers serving in HMS Ark Royal between January 1988 and June 1989 with regard to surgery and anaesthesia at sea is described. The skills and equipment available, techniques used, operations performed and complications that resulted are outlined. The advantages and disadvantages of an active operating policy are discussed and the postulate ventured that in order to achieve maximum efficiency within the medical department of an aircraft carrier such a policy is justified. Finally, in the light of present day litigious trends, the question of the propriety of the policy is posed.

NBCI--another threat to operational effectiveness?

Battle casualties are well recognised as a threat to Operational Effectiveness (OE) at times of conflict. Less well appreciated is that naturally occurring illnesses and injuries--Non-Battle Casualties and Injuries (NBCI)--continue to present at such times and will add to the problems of fighting the ship. This prospective study showed that NBCI resulted in a total of 1369 man days of lost personnel effectiveness among some 1738 RN servicemen during a 180 day deployment. That is just 0.42% of the possible man working days. This represents a loss of 4.3 man days per 1000 at risk per day in terms of fitness for Full Duties or 2.74/1000/day excluding those able to perform Light Duties. It is unlikely that such rates would affect the OE of the fighting units but they do represent a significant challenge to the Royal Naval Medical Service to continue to maintain the rates at such low levels, so that when aggregated to the numbers of battle casualties, OE is maintained as far as possible.

The boat people of Vietnam. Rescue on the South China Sea.

Poor economic conditions in Vietnam have encouraged large numbers of people seeking a better life in the West to join the flow of political refugees leaving the country as "boat people". We report the events surrounding one such group of people who were rescued from the South China Sea by the Outback 88 Task Group.

The Royal Naval Medical Stores for Service Afloat: a prospective quantitative study.

The contents of the scale of Medical Stores for Service Afloat must provide adequate quantities of drugs to allow proper patient care in a variety of situations often remote from specialist support. The overall make up of the scale is difficult to envisage outside the context for which it was conceived. This study was designed to assess the accuracy of the make up of the scale in three RN ships over a six-month period during a detached deployment. During this time the usage of all consumable items was specifically recorded and the outcome subjected to rigorous analysis in relation to the present scale. The results of the study indicate that in the case of both HMS Ark Royal (AR) and the two smaller ships HMS Edinburgh and HMS Sirius (ES) the quantities of drugs in the majority of cases are in excess of requirements. Of the 290 (AR) and 266 (ES) individual drugs 68% and 40% respectively could safely be reduced by varying amounts, whereas only 7.6% and 4.9% respectively needed to be increased. Furthermore, when these changes are costed the savings that result are 7806 pounds for the AR scale and 1532 pounds for the ES scale. Extrapolation of these figures across the surface fleet produces an overall saving on the costs of drugs of over 87,000 pounds.

Early return to work following highly selective vagotomy.

In the Royal Navy, after surgery, the time that servicemen spend away from work and the level of duty to which they return are decisions made by the surgeon, not the general practitioner. In a prospective study, we have thus been able to assess the acceptability of return to full duty at decreasing intervals after highly selective vagotomy (HSV). Seventy-eight servicemen who underwent HSV for duodenal ulcer were studied in three periods, 1978-1980, 1981-1982, 1983-1986, each with a shorter interval to return to duty. There were no differences in the rates of ulcer recurrence, incisional hernia, or ability to perform full duties. After HSV the mean time to return to full duties for each group was 29.3, 16.4, and 4.2 weeks, respectively. Every patient returned to full duties at 28 days was able to perform any assigned task whether at sea or ashore.

von Recklinghausen's disease of nerves: a modern day social response.

We describe a patient with von Recklinghausen's Disease of Nerves whose appearance provoked an emotive reaction in the close community of an RN ship akin to that reported in the case of Sir Frederick Treves' "Elephant Man". The RN divisional system provided a valuable contribution to the resolution of the problems created.

Fine needle aspiration cytology as part of a three stage diagnostic approach to breast lumps in a District general hospital.

Recent studies from specialist breast centres have suggested that fine needle aspiration cytology in conjunction with mammography and clinical examination can provide a prompt and accurate diagnosis of breast lumps. These three methods of diagnosis have been assessed in the context of a district general hospital by analysing 104 consecutive breast lesions with known histology, of which 75 were benign and 29 malignant. The results are presented in terms of the sensitivity and specificity for each method. Fine needle aspiration cytology had a sensitivity for malignancy of 88% (n = 26) and a specificity of 97% (n = 58). Similarly, sensitivity for mammography was 95% (n = 20) and clinical examination 90% (n = 29). Respective specificities were 96% (n = 45) and 83% (n = 75). In none of the 29 patients with breast cancer were all three modalities negative. It is concluded that without specialist breast clinicians and cytologists, a combination of fine needle aspiration cytology, clinical examination and mammography can still provide a degree of preoperative diagnostic accuracy comparable with specialist centres, allowing prompt counselling with all the subsequent benefits.

A multicentre study to compare piperacillin with the combination of netilmicin and metronidazole for prophylaxis in elective colorectal surgery undertaken in district general hospitals.

We have conducted a multicentre randomized study to compare piperacillin with the combination of netilmicin and metronidazole in patients undergoing elective colorectal surgery. There was no significant difference in the incidence of operation-related infection, chest or urinary tract infection. Major life-threatening sepsis occurred in 6% and the overall incidence of operation-related infection was 24%. Organisms which normally inhabit the bowel lumen were cultured from most of the postoperative infections; however, Staphylococcus aureus was isolated as a causative organism in nine patients in the piperacillin group compared with none in the netilmicin and metronidazole group. We are concerned at the high incidence of infection in both groups, and we believe that other factors in addition to prophylactic antibiotics need to be evaluated if the incidence of infection is to be reduced further.
