Twenty-three consecutive patients with duodenal ulceration complicated by pyloric stenosis who came under the care of one surgeon were treated by highly selective vagotomy (HSV) combined with digital dilatation of the stenosis through a gastrotomy. No form of drainage procedure was used. Thus the antral "mill" and the pyloric sphineter were left intact. Since the stenosis is usually distal to the pylorus rather than truly pyloric such dilatation does not damage the pyloric ring, although it may on occasion lead to perforation of the first part of the duodenum. The subsequent progress of these patients was compared with that of a similar, consecutive series of 23 patients with pyloric stenosis who were treated by truncal vagotomy with a drainage procedure by other surgeons on the same surgical unit. Patients were followed up for between four months and five years. The clinical assessment was carried out in "blind" fashion at a special gastric follow-up clinic. No evidence of recurrent ulceration was found in either group of patients. Two patients from each group subsequently came to reoperation for the relief of gastric stasis. Twenty-two of the 23 patients (96%) who had undergone HSV plus dilatation eventually achieved a good-to-excellent clinical result (Visick grades 1+2), wheras only 17 of the 23 patients (74%) who had undergone truncal vagotomy with drainage achieved such a result. The main clinical difference between the two groups was that side effects such as diarrhoea and abdominal pain or discomfort were more common after vagotomy with drainage than after HSV. These results bear witness to the remarkable propulsive powers of the gastric antrum after HSV, which were evidently sufficient to overcome any tendency to re-stenosis in more than 90% of patients. The 9% incidence of failure due to re-stenosis could perhaps be avoided if a small duodenoplasty were performed instead of simple digital dilatation. The results support the hypothesis that damage to the antral mill and pyloric sphincter can be avoided in the course of operations for "pyloric" stenosis secondary to duodenal ulceration. Avoidance of the drainage procedure is of benefit to the patient, just as it is in patients who have duodenal ulceration without stenosis.

It has been proposed that patients with dyspepsia can be classified into symptom groupings that may represent different pathophysiological entities; however, it remains to be shown that distinct symptom subgroups exist. To estimate the prevalence of dyspepsia (defined as upper abdominal pain) and dyspepsia subgroups, an age- and sex-stratified random sample of Olmsted County, Minnesota, residents, aged 30-64 years, were mailed a valid self-report questionnaire; 82% responded (n = 835). Subgroups were as follows: those with symptoms suggestive of peptic ulceration (ulcerlike dyspepsia), those with gastric stasis (dysmotilitylike dyspepsia), those with gastroesophageal reflux (refluxlike dyspepsia), and the remainder (unspecified dyspepsia). Ulcerlike dyspepsia was the commonest subgroup (prevalence, 16.0/100; 95% confidence interval, 13.4-18.5), but 43% of subjects with dyspepsia could be classified into more than one subgroup. Nearly one third of dyspeptics also had irritable bowel symptoms, but these were not confined to any particular dyspepsia subgroup. Although dyspepsia is very common in the community and the majority have ulcerlike symptoms, there is such overlap among the dyspepsia subgroups that a classification based on symptoms alone in uninvestigated patients may not be useful.

Dyspepsia can be defined as the presence of upper abdominal pain or discomfort; other symptoms referable to the proximal gastrointestinal tract, such as nausea, early satiety, and bloating, may also be present. Symptoms may or may not be meal related. To be termed chronic, dyspepsia should have been present for three months or longer. Over half the patients who present with chronic dyspepsia have no evidence of peptic ulceration, other focal lesions, or systemic disease and are diagnosed as having non-ulcer (or functional) dyspepsia. Non-ulcer dyspepsia is a heterogeneous syndrome. It has been proposed that this entity can be subdivided into a number of symptomatic clusters or groupings that suggest possible underlying pathogenetic mechanisms. These groupings include ulcer-like dyspepsia (typical symptoms of peptic ulcer are present), dysmotility (stasis)-like dyspepsia (symptoms include nausea, early satiety, bloating, and belching that suggest gastric stasis or small intestinal dysmotility), and reflux-like dyspepsia (heartburn or acid regurgitation accompanies upper abdominal pain or discomfort). The aetiology of non-ulcer dyspepsia is not established, although it is likely a multifactorial disorder. Motility abnormalities may be important in a subset of dyspepsia patients but probably do not explain the symptoms in the majority. Epidemiological studies have not convincingly demonstrated an association between Helicobacter pylori and non-ulcer dyspepsia. Other potential aetiological mechanisms, such as increased gastric acid secretion, psychological factors, life-event stress, and dietary factors, have not been established as causes of non-ulcer dyspepsia. Management of non-ulcer dyspepsia is difficult because its pathogenesis is poorly understood and is confounded because of a high placebo response rate. Until more data are available, it seems reasonable that treatment regimens target the clinical groupings described above. Antacids are no more effective than placebo in non-ulcer dyspepsia, although a subgroup of non-ulcer dyspepsia patients with reflux-like or ulcer-like symptoms may respond to H2-receptor antagonists. However, there is no significant benefit of these agents over placebo in many cases. Bismuth has been shown to be superior to placebo in patients with H. pylori in a number of studies, but these trials had several shortcomings and others have reported conflicting findings. Sucralfate was demonstrated in one study to be superior to placebo, but this finding was not confirmed by another group of investigators. Prokinetic drugs appear to be efficacious, and may be most useful in patients with dysmotility-like and reflux-like dyspepsia.

We recently have shown that 50% of patients with preoperative gastric outlet obstruction go on to develop chronic nonmechanical gastric stasis after surgery and require further operations in attempts to relieve their symptoms. In the present study we report our experience with completion gastrectomy (CG), offered to a subgroup of this population who failed to respond to both available and experimental medical therapy with prokinetic agents. Manometric studies of the small bowel were performed on three of these patients using a semiconductor solid recording probe to assess the motility of efferent jejunal limbs. There were seven females and one male (N = 8) with a mean age of 45 years. All had persistent symptoms of abdominal pain, bloating, nausea, vomiting, early satiety, decreased appetite, and weight loss dating back to the time of surgery. Gastric stasis was documented by delayed gastric emptying of a radionuclide solid meal (chicken liver labeled with technetium-99m sulfur colloid) with a mean retention of 86 +/- 6.2% (less than 60% being normal) in the setting of an upper endoscopy showing stomal patency. The mean duration of symptoms was 31.6 +/- 15.7 months (range 6-60) since the last surgery. The number of previous gastric operations was a mean of 2.3 per patient. Five of eight patients had undergone a Roux-en-Y procedure as the last operation while the other three had a Billroth II. Surgery consisted of a 90% or complete resection of the remaining stomach and a jejunal-esophageal anastomosis. In some cases the Roux-en-Y limb was lengthened to greater than 45 cm if needed.(ABSTRACT TRUNCATED AT 250 WORDS)

We investigated the safety and efficacy of short-term s.c. administration of metoclopramide in the treatment of symptomatic gastric stasis. Ten patients with gastroparesis, documented by abnormal solid phase radionuclide gastric emptying study, were treated with 10 mg (2 ml) of s.c. metoclopramide every 6 hr for 3 days. Patients gave themselves the injections as outpatients. Questionnaires were then completed concerning symptom relief, local side effects and adverse reactions. A repeat gastric emptying study was obtained immediately after the last dose of metoclopramide. Serum metoclopramide concentrations were obtained at trough, 1, 2, 3, 4 and 5 hr postadministration and serum prolactin levels at trough, 1 and 3 hr. Pharmacokinetic analysis showed mean peak metoclopramide concentration at 30 min of 99.7 +/- 47.1 ng/ml with measured levels of 93.9 +/- 106.83 ng/ml at 60 min and return to trough values by 4 hr; trough prolactins remained elevated above normal values. Gastric stasis improved from a base-line retention of 78.7% of radioisotope at 2 hr to 72.5% after 3 days of therapy (P = .65). Eight patients reported significant improvement in symptomology and two patients reported lessening of symptoms such as nausea, vomiting, bloating, abdominal pain, heartburn and vomiting. The side effects were minimal and did not interfere with completion of the protocol. We demonstrated that s.c. administration of metoclopramide was well accepted by patients and resulted in subjective and objective improvement of gastric stasis. In addition, serum metoclopramide concentrations were comparable with other parenteral routes of administration. Furthermore, serum prolactin levels may provide both a bioassay of efficacy and a marker for monitoring compliance.

Surveys of athletes, primarily runners, have shown that digestive disorders are common, associated both with training and racing. Women, in particular, seem to suffer most commonly. Nearly half have loose stools and nausea and vomiting occur frequently after hard runs. Diarrhoea, incontinence and rectal bleeding occur with surprising frequency. Runners may use medications prophylactically to minimise some of these symptoms. Upper digestive symptoms seem to occur more commonly in multisport events such as triathlons or enduro. The published literature is difficult to analyse and the basic intestinal physiology not well studied. Most gastroenterologists are accustomed to evaluating the fasting patient at rest and exercise physiologists are seldom experienced with digestive techniques. Digestive symptoms occurring with exercise referable to the oesophagus include chest pain, gastro-oesophageal reflux symptoms, or symptoms related to alterations in motility. While little is known of the oesophageal physiology during exercise, it is believed that only minimal changes occur in most subjects. Gastro-oesophageal reflux occurs more frequently with exercise than at rest and may produce symptoms of chest pain suggestive of ischaemic disease. Acid exposure may be reduced by pretreatment with histamine H2-receptor antagonists. Oesophageal symptoms, though common, are rarely disabling to the athlete, and the clinical importance lies in confusion with ischaemic disease. Cases of acute gastric stasis following running have been reported and gastric physiology during exercise, particularly bicycling, has been more actively investigated. Gastric emptying during exercise is subject to a number of factors including calorie count, meal osmolality, meal temperature and exercise conditions. However, it is generally accepted that light exercise accelerates liquid emptying, vigorous exercise delays solid emptying and has little effect upon liquid emptying until near exhaustion. Gastric acid secretion probably changes little with exercise although some have postulated that ulcer patients may increase secretion with exercise. Some exercise-associated digestive symptoms, such as diarrhoea and abdominal pain, have been attributed to changes in intestine function. Small bowel transit is delayed by exercise when measured by breath hydrogen oral caecal transit times and motility may be reduced as well. Intestinal absorption during exercise has not been well evaluated but probably changes little in ordinary circumstances. Passive absorption of water, electrolytes and xylose are not affected by submaximal effort. Colonic transit and function is even more difficult to evaluate and published results have been conflicting. However, it is likely that many of the lower digestive complaints of runners such as diarrhoea and lower abdominal cramps are due to direct effects of exercise upon the colon.(ABSTRACT TRUNCATED AT 250 WORDS)

We have investigated the effect of oral cisapride (10 mg t.i.d.) in a double-blind, placebo-controlled trial in 26 patients with upper gut dysmotility: 11 with gastroparesis (8 diabetic, 3 idiopathic) and 15 with chronic idiopathic intestinal pseudoobstruction. Patients were evaluated at entry and at the end of the 6-wk study by upper gastrointestinal manometry, scintigraphic evaluation of gastric emptying of solids and liquids, measurement of body weight, and scoring of the following symptoms: abdominal pain, nausea, vomiting, early satiety, bloating, and distention. Cisapride and placebo groups were strictly comparable for all parameters assessed. Cisapride resulted in a significant increase in the gastric emptying of solids (p less than 0.05) compared with placebo; cisapride also tended to increase the postcibal antral motility and normalize the abnormal manometric features in the patients with intestinal dysmotility, particularly the characteristics of fasting interdigestive motor complexes and the fed motor pattern. Both cisapride and placebo groups showed an improvement in total symptom scores and there was no significant difference in overall symptom response between the two groups. However, the change in abdominal pain was greater with cisapride (p = 0.07). Cisapride facilitates gastric emptying in patients with upper gut dysmotility. The overall symptomatic benefit during a 6-wk trial of cisapride, 10 mg t.i.d., was not greater than that of placebo, and dose-response as well as longer term trials are necessary to determine the clinical efficacy of this medication.

Symptoms of severe nausea, vomiting, abdominal pain, and frequent bezoars, as well as objective gastric retention, can occur following Roux-Y biliary diversion for alkaline reflux gastritis. Medical therapy and prokinetic drugs have proven ineffective. This review evaluates 37 patients who underwent further gastric resection from 1979 to 1987 to improve gastric emptying and resolve symptoms. Fifteen patients underwent perioperative radionuclide solid-food gastric emptying studies. Seventy-three per cent (27 of 37 patients) of the patients who underwent further gastric resection (70% to 95%) had a satisfactory postoperative response. Twenty patients were graded Visick 1 or 2 and 7 Visick-3 patients, although much improved, still had some symptoms of gastroparesis. Twenty-seven per cent (10 of 37 patients) failed to improve and underwent completion total gastrectomy. Overall, 70% of this group had almost complete resolution of their symptoms. Three of 10 patients were considered "failures" due to postprandial pain in 1 and early vasomotor dumping in 2. Of the 10 patients who failed initial revisional surgery, 7 underwent a 70% to 80% subtotal gastric resection (STG) and 3 patients underwent 85% to 95% extensive resection (EXT.G.). Of the 15 patients who underwent perioperative radionuclide evaluation, a mean two-hour gastric retention of 61.4% +/- 4% (SEM) decreased to 25% +/- 4% following further gastric resection. Eight patients were in the STG group and seven patients were in the EXT.G group. Following STG, mean two-hour gastric retention of 58.2% +/- 3.5% decreased to 38% +/- 3% (p less than 0.05). In seven patients who underwent EXT.G, mean two-hour retention of 65% +/- 4% decreased to 10% +/- 2.5% (p less than 0.005). EXT.G resulted in normal gastric emptying and few late failures. In post-Roux-Y patients with symptoms of gastroparesis and documented gastric retention, EXT.G normalizes gastric emptying and restores a better quality of life. Total gastrectomy should be reserved for those patients who are failed by more extensive resection.

The effects of domperidone, a peripherally acting dopamine antagonist, were compared with those of placebo in a double-blind randomized study in 16 patients with idiopathic gastric stasis, chronic symptoms of "nonulcer dyspepsia" (including nausea, vomiting, and abdominal pain), and altered gastroduodenal motility. Patients received either domperidone or placebo orally (20 mg before meals and at bedtime) for six weeks. Symptoms were assessed by daily diaries kept by the patients for two weeks while receiving no medication for their gastrointestinal complaints (baseline), and throughout the six-week treatment phase. Studies of gastric emptying of a radiolabeled solid-phase meal were performed at baseline and six weeks after treatment. All patients had delayed gastric emptying at baseline, defined as a half-emptying time of more than mean + 1 SD (from studies of normal controls). An 18- to 24-hr recording of gastroduodenal motor function during fasting was also performed at baseline and after six weeks of either domperidone or placebo treatment. After six weeks of treatment, the symptom scores significantly improved in the domperidone group (P less than 0.05), but not in the placebo group. Gastroduodenal motor activity was unchanged from baseline recordings after six weeks. Solid-phase gastric emptying also showed no improvement in either the domperidone or placebo group of patients. Although domperidone therapy had no significant effect on motility, it appears to be an effective drug for the treatment of the symptoms of nonulcer dyspepsia.

Patients are often referred for evaluation of a wide range of GI complaints including dysphagia, abdominal pain, bloating, nausea, constipation or diarrhoea. Many are diagnosed with 'functional' disease when endoscopy or conventional radiological studies fail to identify an anatomic cause for the patient's symptoms. In such cases nuclear medicine offers non-invasive methods for objectively demonstrating disease involving different areas of the gastrointestinal tract. Increasingly scintigraphy is playing a primary role in the evaluation of patients with suspected acute cholecystitis, active gastrointestinal bleeding, gastroparesis, and small and large bowel motility disorders. In addition, it supplements other studies when results are inconclusive in diagnosing oesophageal dysmotility, gastro-oesophageal reflux, acalculous cholecystitis, and postoperative complications of gastrointestinal surgery.
