New techniques in the study of gut motility must aim to improve our understanding of the flow of luminal contents, since this is the ultimate function of such motility. This paper reviews some areas of gastroduodenal motility relevant to our understanding of duodenogastric reflux. Antroduodenal motility has been studied in the past both manometrically and radiologically, but the function of the pylorus remains in doubt. Observations made using a new impedance technique at endoscopy on the timing of pyloric closure during antroduodenal motor activity suggest that the pylorus, in addition to being a functional appendage of the terminal antrum, can contract independently and in association with isolated duodenal contractions to prevent reflux. Retroperistaltic duodenal contractions, however, may not close the pylorus in time to prevent reflux, and duodenal activity rather than the pylorus may be the key to duodenogastric reflux. Studies using invasive techniques have implicated reflux in the aetiology of some gastric ulcers and
gallstone
dyspepsia
. Non-invasive studies on reflux with the HIDA radionuclide scan have confirmed that reflux is minimal in normal subjects, more common in
gallstone
dyspepsia
, and related to gallbladder function.

Of 125 patients with radiolucent
gallstones
in functioning gallbladders treated with chenodeoxycholic acid (CDCA) between 1971 and 1977, 47 showed complete
gallstone
dissolution--an overall efficacy of 38%. However, a retrospective analysis of factors governing efficacy carried out in 1976 showed that in patients with stones less than 15 mm in diameter, treated with greater than 13 mg CDCA kg-1 day-1 for not less than one year who developed unsaturated bile (n = 27), efficacy rose to 78% complete and 93% partial plus complete
gallstone
dissolution. The usefulness of this selection/management approach was then confirmed prospectively in 42 comparable patients selected for treatment since 1977, efficacy (complete
gallstone
dissolution) reached 76%. The median duration of treatment for complete
gallstone
dissolution was 7.5 months for stones less than 5 mm in diameter, 12.0 for 5-10 mm stones; 22.0 for 10-15 mm stones and 28.5 for the only two patients (of 26) with large (greater than 15 mm) stones who ultimately showed complete
gallstone
dissolution. Seventy-eight patients withdrew from therapy, 21 within 6 months of starting CDCA (before their first follow-up cholecystogram): the remaining 57 withdrew because of: complications of
gallstones
(11 patients), inadequate treatment (dose and/or duration, 20 patients), inappropriate selection or unsuitable stones (19 patients) and resistance to CDCA (7 patients). Diarrhea, although common, was usually mild or transient. Biliary colic and non-specific
dyspepsia
tended to improve during therapy. To date,
gallstone
recurrence has been detected in 14 patients (30%), 3 months to 5 years after discontinuing treatment with CDCA.

In two groups of
gallstone
patients ideally suited for medical treatment, the effect of six to 18 months' therapy was compared retrospectively in 52 given chenodeoxycholic acid (CDCA) and 46 given ursodeoxycholic acid (UDCA). The minimum dose (mg kg-1 day-1) required to desaturate bile consistently was 10.1 for UDCA and 14.3 for CDCA. In patients completing six months' treatment, 23 of 35 (66%) taking a mean of 7.7 (+/- SEM 0.5) mg UDCA and 34 of 42 (81%) taking 14.7 +/- 0.2 mg CDCA showed partial or complete dissolution of
gallstones
. The mean dose in the UDCA-treated patients, however, was artefactually lowered by previous dose-response studies: in those who had not taken multiple doses, the mean UDCA intake in the 'responders' at six months was 9.1 +/- 0.3 mg kg-1 day-1. At six months, more UDCA (five of 35 or 14.3%) than CDCA (four of 42 or 9.5%)-treated patients showed complete dissolution of
gallstones
, but, by one year, the situation was reversed, 20 of 41 (49%) CDCA-treated and eight of 30 (27%) UDCA-treated patients showing complete dissolution of
gallstones
. Cumulative efficacy at one year had risen to 76% for UDCA and 89% for CDCA. Both treatments reduced the frequency of
dyspepsia
and biliary colic; 37% of CDCA and 2.6% of UDCA-treated patients showed hypertransaminasaemia; diarrhoea developed in 60% of the CDCA group but in none of the UDCA group.

In a randomized controlled trial, 299 patients were sent a symptoms questionnaire 1 year after laparoscopic (n = 151) or minilaparotomy (n = 148) cholecystectomy for symptomatic
cholelithiasis
. The response rate to the questionnaire from contactable patients was 86 per cent. In both groups, at least 90 per cent of patients reported that their symptoms were improved, and at least 93 per cent rated the success of their operation as 'excellent', 'good', or 'fair'. However, over half the patients reported abdominal pain, a quarter reported flatulence, and a quarter
dyspepsia
. The only difference between treatment groups was that a higher proportion of patients who underwent minilaparotomy reported heartburn (35 per cent versus 19 per cent, P = 0.005). Patients who reported a 'poor' outcome were more likely to have suffered a postoperative complication, had lower quality of life scores, and higher anxiety and depression scores. Both laparoscopic and minilaparotomy cholecystectomy result in symptomatic benefit in at least 90 per cent of patients with symptomatic
cholelithiasis
.

Somatostatinoma is one of the rarest tumours of the endocrine pancreas. Cardinal manifestations of a somatostatinoma include
gallstones
, mild diabetes mellitus, steatorrhoea, diarrhoea and
dyspepsia
. Like any other pancreatic islet cell carcinoma, a somatostatinoma may also produce several different hormones such as adrenocorticotropic hormone, calcitonin, vasoactive intestinal polypeptide, pancreatic polypeptide, gastrin, insulin, and glucagon. In many cases, the clinical picture is dominated by the effect of these other hormones. We present a patient with somatostatinoma in which an immunocytochemical study of the specimens from pancreas and liver showed a weak positive reaction for gastrin besides a strong positive reaction for somatostatin. Interestingly, this patient also showed the signs of carcinoid syndrome which was successfully treated with octreotide.

Dyspepsia
is a frequent presenting symptom amongst patients attending medical clinics worldwide. However their aetiologies differ geographically. The present study was conducted to identify the aetiologies of
dyspepsia
of our centre and to determine their clinical characteristics. Five hundred consecutive patients presenting with
dyspepsia
were studied at our Institute. All patients underwent detailed structured questionnaire, stool examination, upper gastrointestinal endoscopy, ultrasound scan of upper abdomen and sigmoidoscopy when necessary. Among 500 patients, 34% suffered from essential
dyspepsia
, 28% had peptic ulcer, 19.2% had
cholelithiasis
, 10.8% had irritable bowel syndrome and 6% had gastro-oesophageal reflux. Significantly more patients with peptic ulcer experienced night paints, pain relief with food, milk, antacids or H2 receptor antagonists and periodic pain. In patients with essential
dyspepsia
, pain was continuous, mild to moderate in intensity, aggravated by food or alcohol, without relief with milk, antacids or H2 receptor antagonists and night pains were absent in them.

As part of a continuing audit of patients undergoing laparoscopic cholecystectomy (which now numbers over 1500) 468 of the 508 patients (92.1 per cent) operated on between October 1989 and March 1991 were studied between 350 and 988 days after the operation (mean 19 months). A questionnaire was filled in by each patient before operation and at the late follow-up visit. Eight specific symptoms were sought-non-colicky pain, colic, abdominal distension, nausea, vomiting, loss of appetite, flatulence, and dietary restriction. The result of each operation was assessed by two surgeons and by the patient. In 453 patients (96.8 per cent) the symptoms had improved as a result of the operation, but 260 patients (55.6 per cent) had some abdominal symptoms. The result was assessed as excellent in 310 patients (66.2 per cent); 143 (30.5 per cent) still had abdominal complaints but they were willing to cope with those symptoms. In 15 patients (3.2 per cent) the result was unsatisfactory. Statistical analysis of 26 preoperative variables showed few significant differences between patients with excellent results and patients with persisting or new symptoms. The percentage of patients with biliary colic was reduced from 82.9 per cent before to 6.4 per cent after laparoscopic cholecystectomy (P < 0.05), and of those with flatulence from 62.6 per cent to 45.3 per cent (P < 0.05). Flatulence persisted in 147 (50.2 per cent) of the 293 patients who had complained of flatulence before the operation, and of the 175 patients who had not complained of flatulence before surgery, 65 (37.1 per cent) reported the symptom for the first time after the operation. It appears that 'flatulent
dyspepsia
' after cholecystectomy has many causes, one of which may be removal of the gallbladder. It is concluded that the long-term results of laparoscopic cholecystectomy in patients with symptomatic
gallstone
disease were excellent but the prognosis in individual patients was unpredictable.

Many physicians consider
gallstones
to be a cause of vague upper abdominal discomfort. However, both
dyspepsia
and
gallstones
are common conditions in the general population, and the relationship between the two has continued to generate controversy. In this editorial, I review the evidence for and against a relationship between
gallstones
and
dyspepsia
. The data suggest that upper abdominal discomfort, heartburn, bloating, and other vague symptoms are not related to
gallstones
and the routine ordering of an ultrasound in the patient with
dyspepsia
is not warranted.

In this prospective, clinical study, four groups, each consisting of 12 patients were established to determine how gastric emptying is influenced in
cholelithiasis
with accompanied flatulent
dyspepsia
and the relationship of symptoms and gastric emptying after cholecystectomy: group 1--healthy people; group 2--patients with dyspeptic
cholelithiasis
; group 3--patients with no
dyspepsia
after cholecystectomy; group 4--patients with
dyspepsia
after cholecystectomy. Groups are compared according to solid phase gastric emptying scintigraphies performed with Tc 99m sulphur colloid bound with scrambled eggs. Gastric emptying delayed in groups 2 (P < 0.001) and 4 (P < 0.005) postprandially and did not differ in the group 3 (P > 0.005). These results demonstrate that
dyspepsia
, in
cholelithiasis
and persisting after cholecystectomy, has a close relation with delay in gastric emptying.

The aim of the present study was to determine the pattern of structural and functional disorders encountered in an Asian gastroenterological clinic and to compare this pattern with findings from Western centres. Consecutive new patients (totalling 2384) attending the clinics of two consultant gastroenterologists were studied. Of these, 2141 suffered from gastroenterological problems. One thousand and sixty-three (49.6%) had structural diseases, the commoner ones being liver disease, peptic ulcer, malignancy, haemorrhoids and
gallstones
. The remainder who were found to have no structural disease (n = 1078; 50.4%) were deemed to have functional disorders including non-ulcer
dyspepsia
, irritable bowel, simple constipation and functional diarrhoea. The proportions of functional and structural disease were similar to those in the West. Major differences included a higher frequency of hepatoma and a lower frequency of inflammatory bowel disease and gastro-oesophageal reflux in the present series.
