Cancer of ileostomy: a late complication of colectomy for ulcerative colitis.
Cancer arising at an ileostomy site represents a rare late complication of total colectomy performed for ulcerative colitis. There are no more than 36 published cases in the literature. We describe a case of adenocarcinoma of the mucocutaneous junction at the ileostomy site, occurring 31 years after total colectomy for ulcerative colitis. Wide excision of the moderately differentiated adenocarcinoma was performed with refashioning of the ileostomy. Polypoid adenomas or adenocarcinomas of the ileostomy after colectomy performed for non-neoplastic conditions are extremely uncommon. Biopsies of polypoid lesions at the stoma site are recommended.

Postoperative stay following colorectal surgery: a study of factors associated with prolonged hospital stay.
AIM: To study the factors that contribute to postoperative stay following colorectal surgery. DESIGN: A prospective observational study. SETTING: Three colorectal surgical units - a teaching hospital, a large district general hospital and a district general hospital. PARTICIPANTS: 350 patients undergoing colorectal surgery. MAIN OUTCOME MEASURES: 28 pre-, peri- and postoperative patient- and treatment-related factors. RESULTS: Stepwise regression analysis suggests that the factors that significantly lengthen postoperative stay include a low albumin on admission, stoma formation, operative blood loss, urinary and respiratory complications, wound infections, postoperative ventilation and social delay at the time of discharge. The postoperative stay was not affected by patient age or by the seniority of the surgical team. CONCLUSIONS: Factors have been identified that determine the postoperative length of stay. These data may allow better planning and treatment of patients undergoing colorectal surgery.

Randomized clinical trial assessing the side-effects of glyceryl trinitrate and diltiazem hydrochloride in the treatment of chronic anal fissure.
INTRODUCTION: Glyceryl trinitrate (GTN) ointment (0 small middle dot2 per cent) has an efficacy of up to 68 per cent in healing chronic anal fissure, but with headache as a major side-effect. Diltiazem hydrochloride (DTZ) cream (2 per cent) is expected to have fewer side-effects. METHODS: A prospective double-blind randomized two-centre trial requiring at least 26 patients in each group (alpha = 0.05, beta = 0.9) was instituted after approval of the local ethics committee, to compare the incidence of side-effects (primary endpoint) with 0.2 per cent GTN ointment and 2 per cent DTZ cream in the treatment of chronic anal fissure. Treatments were applied perianally, twice daily for 6-8 weeks. All patients gave written informed consent. RESULTS: Both groups were comparable in patient demographics and clinical characteristics. Twelve patients violated the protocol, withdrew or did not attend follow-up. There were more side-effects with GTN (21 of 29 patients) than with DTZ (13 of 31) (relative risk (RR) 1.84 (95 per cent confidence interval (c.i.) 1.11 to 3.04), P = 0.01). In particular, more headaches occurred with GTN (17 of 29 patients) than with DTZ (eight of 31) (RR 2.06 (95 per cent c.i. 1.18 to 3.59), P = 0.01). There were no significant differences in healing and symptomatic improvement rates between patients receiving GTN (25 of 29) and DTZ (24 of 31). DISCUSSION: DTZ cream caused substantially fewer headaches than GTN ointment. There was no significant difference in the healing or improvement of chronic anal fissure between the treatments. DTZ may be the preferred first-line treatment for chronic anal fissure.

Operative mortality rates among surgeons: comparison of POSSUM and p-POSSUM scoring systems in gastrointestinal surgery.
PURPOSE: The original Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity and the more recent Portsmouth predictor equation for mortality scoring systems were developed to provide risk-adjusted mortality rates in general surgery. The aim of this study was to compare crude and risk-adjusted operative mortality rates among four surgeons using the above scoring systems and assess their applicability for patients scored retrospectively. METHODS: A total of 505 consecutive patients undergoing major gastrointestinal surgery were analyzed; 65 percent underwent colorectal, 27.5 percent underwent upper gastrointestinal, and 7.5 percent underwent small-bowel surgery. The observed:predicted mortality ratios using the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity and Portsmouth predictor equation for mortality scoring systems were calculated for each surgeon. RESULTS: The actual overall operative mortality rate was 11.1 percent (elective was 3.9 percent, and emergency was 25.1 percent). The Portsmouth predictor equation for mortality equation predicted a mortality rate of 11.3 percent (P = 0.51). However, the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity scoring system was found to overpredict death by a factor of two: 21.5 percent (P < 0.001). Mortality rates among the four surgeons varied from 7.6 to 14.7 percent but depended on the proportion of elective vs. emergency surgery. The observed:predicted ratio for Portsmouth predictor equation for mortality was close to unity (0.905-1.067) for all surgeons, but it was 0.45 to 0.56 for Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity. CONCLUSION: The Portsmouth predictor equation for mortality equation seems to be a more accurate predictor of mortality in gastrointestinal surgery. It would seem to provide the best choice for analyzing operative mortality rates for individual surgeons, taking into account variation in case mix and fitness of patients even when scored retrospectively. This has important implications for the future assessment of surgeons' clinical standards and the assessment of quality of surgical care.

An unusual cause of thigh pain in colonic cancer. Inflammatory oncotaxis?
Colonic carcinoma metastasis in order of frequency to the liver, lung, bone and brain. Metastases elsewhere are unusual. We report a very rare case of metastatic spread to skeletal muscle and skin. There follows a review of the theories of anomalous metastatic localization. Inflammatory oncotaxis is offered as the most likely explanation of this phenomenon. The importance of good history taking in colorectal cancer follow up clinics is emphasised.

Glyceryl trinitrate treatment of chronic fissure in ano: one year's experience with 0.5% GTN paste.
OBJECTIVE: Assessment of the efficacy of topical 0.5% glyceryl trinitrate (GTN) paste in the treatment of chronic fissures in ano. PATIENTS AND METHODS: Forty-five patients were treated with 0.5% GTN paste and reviewed at 3, 6 and 12 weeks to assess symptoms, side effects and fissure healing. RESULTS: At 6 weeks, 73% of patients had no fissures. In 27% of cases treatment was unsuccessful. At three month follow up there was no early recurrence. The prevalence of headaches was 84% with 11% headache related non-compliance. CONCLUSIONS: The use of 0.5% GTN induces rapid healing of chronic anal fissures with a 73% healing rate in this study. Successful treatment may come at the expense of a high incidence of headaches and a lower compliance than found in studies involving a lower concentration of GTN. A balance is required between fissure healing and headache intolerance.

Indoor racquet sports injuries.
Family physicians can care for most patients injured while participating in indoor racquet sports. However, patients with injuries to the eye usually require ophthalmologic referral. The most common injuries that occur in persons participating in indoor racquet sports include contusions, sprains and strains, lacerations, eye injuries, bursitis and tendinitis. Musculoskeletal injuries that merit special consideration include lateral epicondylitis, DeQuervain's tenosynovitis, wrist intersection syndrome, patellar pain syndrome, meniscal injuries, Achilles tendinitis and plantar fasciitis. The family physician plays a critical role in providing patients with information about preventive measures.

Study of belching ability in antireflux surgery patients and normal volunteers.
The ability to belch was evaluated by a novel test, after gaseous stomach distension to standard volume, in 16 patients after antireflux surgery and nine healthy volunteers. A structured assessment of dyspeptic symptoms was also carried out in both groups. Repeat studies in volunteers showed acceptable reproducibility for the new test of belching capacity (within-subject coefficient of variance 4.5 per cent). After antireflux surgery, patients had lower volume individual belches (median(range) 27.5(0-104) ml in patients versus 76(15-165) ml in volunteers; P less than 0.02) and belched less gas within 1 h of the stimulus than volunteers (median(range) 205(0-1363) ml in patients versus 456(45-818) ml in volunteers; P less than 0.05). Belching frequency was similar in both groups. The incidence and severity of symptoms were unrelated to belched gas volumes.

Computerised method for acquisition and display of gastrointestinal motility data.
A computerised system is developed for the acquisition and display of gastrointestinal motility data which utilises a purpose developed software program called 'PC-motil', running on an IBM compatible microcomputer. 'PC-motil' displays data during collection, writes data to disk file and compresses all data at the end of a study on to a single monitor screen for convenient overview. Any area of interest, in single or multiple channels, may be selected and expanded for detailed examination. This system is tested by the recording of gastric and jejunal motility patterns of 11 healthy volunteers in fasting and fed states. All antral and jejunal migrating motor complexes (MMCs) in fasting studies, as well as all fed motility patterns were recognisable in both 'compressed' and 'expanded' form. The reproduction of motility patterns by the computer based system was indistinguishable from that of a conventional analogue chart recorder. This computerised system provides a convenient and cost-effective means of acquisition, storage and display of motility data in digital form.

Abnormal esophageal transit in patients with typical reflux symptoms but normal endoscopic and pH profiles.
There is a small, well-known cohort of patients who, despite classic reflux symptoms, have a normal esophageal pH profile and endoscopic picture. The treatment of these patients has proved problematic. In an attempt at determining the pathophysiology of this subgroup, we investigated the esophageal transit, using the radiolabeled solid bolus esophageal egg transit technique, in 58 such patients: 25 males, 33 females, mean age 39.5 years (range: 13 to 65 years). The egg transit was normal in 31 (53.4%) patients. In the remaining 27 (46.6%) patients, the condensed image analysis showed the following specific abnormal transit patterns: "step" delay pattern, demonstrating segmental hold-up in mid- or distal esophagus in 16 (59.3%); nonspecific delay in 6 (22.2%); oscillatory pattern in 3 (11.1%); and total nonclearance during the study period (4 minutes) in 2 (7.4%) patients. The patients with abnormal transit patterns had demographic parameters and symptom scores similar to those found in patients with normal transit. This study shows that almost 50% of patients with reflux symptoms and negative pH and endoscopy have abnormal esophageal transit, and almost two thirds of these patients display segmental transit delay in the lower half of the esophagus. The effect on symptomatology by prokinetic agents in the patient subgroup needs evaluation.

Evidence for hypomotility in non-ulcer dyspepsia: a prospective multifactorial study.
A prospective multifactorial study of symptoms and disturbance of gastrointestinal function has been undertaken in 50 patients with non-ulcer dyspepsia. Objective tests including solid meal gastric emptying studies, gastric acid secretion, E-HIDA scintiscan for enterogastric bile reflux, and hydrogen breath studies were carried out in all patients and validated against control data. Gastroscopy and biopsy were carried out in non-ulcer dyspepsia patients only. Non-ulcer dyspepsia patients were categorised on the basis of predominant symptoms as: dysmotility-like dyspepsia (n = 22); essential dyspepsia (n = 14), gastro-oesophageal reflux-like dyspepsia (n = 11); and ulcer-like dyspepsia (n = 3). In the total non-ulcer dyspepsia population, solid meal gastric emptying was delayed (T50 mean (SEM) = 102 (6) minutes (patients) v 64 (6) minutes (controls), (p less than 0.01) and high incidences of gastritis (n = 26) and Helicobacter pyloridis infection (n = 18) were found. An inverse correlation was observed between solid meal gastric emptying and fasting peak acid output (r = -0.4; p less than 0.01). Indeed gastric emptying was particularly prolonged in eight patients (T50 mean (SEM) = 139 (15) minutes) with hypochlorhydria. In the non-ulcer dyspepsia population oral to caecal transit time of a solid meal was delayed (mean SEM = 302 (14) minutes (patients) v 244 (12) minutes (controls) (p less than 0.01]. Seven patients had a dual peak of breath hydrogen suggestive of small bowel bacterial overgrowth. No association was observed between symptoms and any of the objective abnormalities. This multifactorial study has shown that hypomotility, including gastroparesis and delayed small bowel transit, is common in non-ulcer dyspepsia and may be related to other disorders of gastrointestinal function. No relation between symptoms and disorders of function, however, has been shown.

Detection of clustered gastrointestinal contractions in partial intestinal obstruction by surface vibration analysis.
Gastrointestinal contraction "clusters" with alternating quiescence occur in partial intestinal obstruction and are conventionally detected by intraluminal manometry. Surface Vibration Analysis (SVA), which is a noninvasive test, was evaluated in this study in experimental and clinical situations. In the experimental situation, former SVA was assessed against simultaneous manometry in two volunteers, in whom partial obstruction had been induced by intrajejunal balloon distension. Manometry showed typical contraction "clusters" with alternating quiescence, each of two to four minutes duration, in obstructed jejunum proximal to the balloon. The distal jejunum was inhibited. SVA showed a pattern of hyperactivity and quiescence corresponding to proximal jejunal activity. In the clinical situation, SVA recordings taken after a standard meal in nine patients with suspected chronic obstruction adhesive obstruction, (subsequently proven in seven patients and disproved in two), and 36 volunteers were compared. All patients with proved obstruction showed an SVA pattern of alternating hyperactivity and quiescence. This pattern was not observed in volunteers or nonobstructed patients.

Gallbladder function and fasting enterogastric bile reflux.
The relationship between gallbladder function and duodenogastric reflux of bile has been investigated in the fasting phase by 99Tcm-EHIDA biliary scintigraphy in 370 patients with abdominal pain. This isotope is cleared from the blood-pool by hepatocellular function and is excreted into the biliary tract. Obstruction of the common bile duct was found in 79 patients, leaving 291 who were evaluable for duodenogastric bile reflux. Gallblader function was present in 169 and absent in 122 patients. Duodenogastric reflux of bile was observed in 82 patients, 10 of whom had had previous gastric surgery. Only 298 of 169 (17%) patients with a functioning gallbladder showed evidence of enterogastric bile reflux compared to 43 of 122 (35%) with absent gallbladder function (p less than 0.005 by Chi Square). These results suggest that continuous bile flow into the duodenum in the absence of a functioning gallbladder facilitates duodenogastric reflux.

Surface vibration analysis (SVA): a new non-invasive monitor of gastrointestinal activity.
A computerised system for measurement of vibration at the abdominal surface was constructed which was addressed to the evaluation of gastrointestinal (GI) motor function. Preliminary studies revealed a dominant low frequency signal which was synchronous with the heartbeat and was considered representative of aortic pulsation. This was excluded by selective spectral filtration. The remaining signal was processed and measured by computer, with provision of quantitative energy values as well as of graphic display. The developed method, called surface vibration analysis (SVA) has been evaluated clinically; (a) against oral to caecal transit times (OCCT) of a standard solid meal, in five patients with severe postgastrectomy diarrhoea, seven patients with mild idiopathic diarrhoea and 22 healthy volunteers. (b) against prokinetic effects of a gastrointestinal stimulant (cisapride) in nine patients. In (a) postprandial SVA energy measurements were greater (SVA [*X (SEM)] = 406,933 (98,224] and oral to caecal transit of the solid meal was more rapid (OCTT = *90 (29) min) in the severe diarrhoea patients [postgastrectomy] than either the mild diarrhoea group (*SVA = 235,317 (50,780); *OCTT = *199 (42) min) or normal volunteers (*SVA = 212,062 (27,153); *OCTT = 242 (19) min) [p less than 0.01 for SVA and OCTT]. In the total group, an inverse correlation was observed between quantitative SVA energy values and oral to caecal transit times of solids (Spearman's rho = -0.486; p less than 0.01). In (b), drug stimulation of the GI tract caused an increase of fasting SVA measurements from *21,217 (5956) [before] to *41,937 (9606) [after] intravenous cisapride (p less than 0.05). This new technique may be useful for evaluation of gastrointestinal motor activity.
