Pain is difficult and sometimes frustrating to treat, even though new devices and new approaches have been developed in recent years. Pain varies tremendously from one patient to the next, and there are also some studies suggesting that the intensity of pain varies according to time of day. In animal experiments, a relationship between the reaction to pain and the rhythmicity of plasma endorphin concentrations was suggested because reactions to pain (such as jumping from a hot plate) were in phase with plasma endorphin levels: latencies were longest and plasma levels were highest during the resting period of rodents. In human studies, pain induced experimentally was reported to be maximal in the morning, or in the afternoon or at night. These divergent findings may be due to methodological differences, as pain was produced by different methods, many parameters were used to quantify pain intensity, and the psychological aspect of pain was rarely considered by authors. A circadian pattern of pain was found in patients suffering from pain produced by different diseases. For instance, highest toothache intensity occurred in the morning, while biliary colic, migraine, and intractable pain were highest at night. Patients with rheumatoid arthritis reported peak pain early in the morning, while those with osteoarthritis of the knee indicated that the maximal pain occurred at the end of the day. The effectiveness of opioids appears also to vary according to time of day, but large differences in the time of peak and low effects were found. Investigators found that peak pain intensity and narcotic demands occurred early in the morning, while others found maximal pain at the end of the day. Pain is a complex phenomenon and efforts should be made to standardize the methods used in studies and to describe accurately the diseases causing pain because the patterns of pain may be specific to each clinical situation. Further research should be aimed at characterizing the chronobiology of pain in different experimental and clinical situations and to determine when the analgesic drugs are producing maximal effectiveness. This information is needed before clinicians can be persuaded to use chronopharmacological data when they prescribe analgesic drugs to their patients.

From 1990 through 1993, we treated 36 patients with recurrent typical biliary colic but who showed no ultrasonic evidence of cholelithiasis by laparoscopic cholecystectomy. Associated symptoms included nausea (75%), bloating (56%), fatty-food intolerance (53%), vomiting (17%), weight loss (31%), bowel irregularity (28%), reflux or dyspepsia (25%), and fever (17%). Diagnostic evaluation included ultrasound (100%), upper gastrointestinal series (36%), oral cholecystogram (14%), computed tomographic scan (39%), endoscopic retrograde cholangiopancreatography (17%), upper gastrointestinal endoscopy (14%), and hepatobiliary scan (92%). Quantitative hepatobiliary scans in 33 patients revealed a low gallbladder ejection fraction (EF) of less than 35% in 29 patients (88%; mean EF = 9%), and 13 patients experienced reproducible pain after cholecystokinin provocation. All patients underwent attempted laparoscopic cholecystectomy; one case of unsuspected acute acalculous cholecystitis was converted to open laparotomy because of unclear anatomy. Gross and histological examination of the gallbladders revealed chronic inflammation (83%), cholesterolosis (31%), cholesterol crystals or small stones (17%), acute inflammation (8%), polyps (6%), and normal histology (6%); however, blind retrospective scoring of gallbladders revealed significant chronic inflammation in only 38%. In the 2 to 40 months (mean, 14 months) since operation, there have been no deaths (97% follow-up). Laparoscopic cholecystectomy relieved pain in 93% of patients with a low preoperative EF compared with 75% of patients with a normal EF (nonsignificant p value). Persistent abdominal or gastrointestinal complaints included flatulence (31%), loose stools or fecal urgency (29%), belching (29%), indigestion (20%), nausea (11%), and "typical" gallbladder pain (9%). We conclude that many patients with symptoms of biliary colic and scintigraphic evidence of biliary dyskinesia have histologic findings of chronic cholecystitis. Although laparoscopic cholecystectomy usually eliminates biliary colic, persistent nonbiliary complaints are frequent.

In a previous study, we have shown that caerulein relieves biliary colic pain in gallstone patients. This study was initiated to determine gallbladder and sphincter of Oddi behaviour during biliary colic and their response to caerulein. In 10 gallstone patients gallbladder volume was measured by real-time ultrasonography during a biliary colic episode and 72 hours after cessation of pain, before and after caerulein administration. Basal sphincter of Oddi pressure was determined by CPRE manometry in 10 gallstone patients during biliary colic and three days after cessation of pain, before and after caerulein. The results of this study show that, during biliary colic, gallbladder volume is 8 times greater than in the post-colic state. Basal sphincter of Oddi pressure was also significantly higher during biliary colic than in the post-colic state. Caerulein relieved in all cases the biliary colic pain while reducing gallbladder volume and decreasing the sphincter of Oddi.

Patients with typical symptoms of biliary tract disease but no gallstones on ultrasonography may benefit from cholecystectomy for presumed chronic acalculous cholecystitis. We retrospectively analyzed the outcome of 50 patients with a preoperative diagnosis of chronic acalculous cholecystitis based upon history (chronic or recurrent, postprandial right upper quadrant abdominal pain), the absence of acid-peptic disease, and normal biliary sonography treated with laparoscopic cholecystectomy (LC) and transcholecystic cholangiography from 1991 to 1996. All patients had preoperative cholecystokinin-stimulated hepatobiliary scintigraphy (CCK-HBS). There were 42 women and 8 men with a mean age of 43 years. CCK-HBS was abnormal in 45 patients (< or = 35 per cent gallbladder ejection fraction or nonfilling of the gallbladder). There was no postoperative mortality and one morbidity (urinary retention). All patients had microscopic evidence of chronic cholecystitis. At mean follow-up of 30 months, (range, 7-62 months) 39 patients (78%) were free of abdominal pain. Thirty-five of 45 patients with abnormal CCK-HBS were pain free (positive predictive value, 0.78). Four of five patients with normal CCK-HBS were pain free (negative predictive value, 0.20). The positive and negative likelihood ratios for CCK-HBS were 0.99 and 1.13, respectively, confirming that this test was not useful for predicting benefit from LC. Seven patients with persistent right upper quadrant pain had abnormal postoperative sphincter of Oddi manometry; they improved after endoscopic sphincterotomy. Patients with symptoms typical of biliary colic with normal gallbladder sonography and absence of acid-peptic disease benefit from LC in the majority of cases. Those who remain symptomatic after LC may benefit from endoscopic retrograde cholangiopancreatography with sphincter of Oddi manometry and endoscopic sphincterotomy when manometry is abnormal.

The expectation that cholecystectomy is effective treatment for symptomatic gallstones is not always achieved in surgical practice. The impact of cholecystectomy on the relief of gastrointestinal symptoms was evaluated in 92 patients followed up after surgery for a mean of 31.1 months (range 12-83 months). Abdominal pain continued to be present, or arose de novo, in 28 (30.4%) patients. Pain-free outcome after cholecystectomy was associated with a preoperative clinical diagnosis of biliary colic, fatty food intolerance, and a thick-walled gallbladder on ultrasound (P = 0.02). Logistic regression associated a thick-walled gallbladder, elevated gamma-glutamyl transpetidase, body mass index < 26, fat intolerance, and normal bowel habit with good postoperative results (P = 0.001). Application of each of these five factors to a clinical index failed to predict long-term pain-free outcome after cholecystectomy. Abdominal bloating (P = 0.03), dyspepsia (P < 0.001), heartburn (P < 0.007), fat intolerance (P < 0.001), nausea (P = 0.001) and vomiting (P < 0.001) were significantly improved after cholecystectomy, but diarrhoea, constipation and excessive flatus were not. Outcome benefit ratios confirmed that vomiting (0.96), nausea (0.87), dyspepsia (0.67), fat intolerance (0.57) and heartburn (0.51) were relieved by surgery. Cholecystectomy improved symptoms compared with a matched control group, suggesting that surgery remains the gold standard treatment of symptomatic gallstones.

Patients with biliary dyskinesia have symptoms consistent with biliary colic and an abnormal gallbladder ejection fraction (GEF) in the absence of cholelithiasis. Cholecystokinin hepatobiliary scan quantifies gallbladder function and may assist in selecting patients with acalculous biliary pain who would benefit from cholecystectomy. Seventy-eight patients with an abnormal GEF (< 35%) on cholecystokinin hepatobiliary scan without cholelithiasis were studied retrospectively. Patients were divided into groups based on diagnosis and treatment. In Group I, the patients who underwent cholecystectomy, 80 per cent (35 of 44) had complete symptomatic resolution whereas the remaining 20 per cent (9 of 44) had symptomatic improvement. Pathology reports demonstrated chronic cholecystitis in 95 per cent of specimens. Group II were patients with symptoms attributable to biliary dyskinesia, but did not undergo cholecystectomy. Persistence of symptoms was noted in 75 per cent (18 of 24) of patients whereas 25 per cent (6 of 24) had symptomatic resolution without any treatment. Group III consisted of patients with an abnormal ejection fraction who had improvement of symptoms after treatment for an alternative diagnosis (n = 10). These findings suggest that an abnormal ejection fraction does not always indicate gallbladder disease. Alternative diagnoses must be investigated and treated. Patients with persistent biliary type symptoms in combination with an abnormal GEF in the absence of other attributable causes can expect a favorable response to cholecystectomy.

This was conducted to evaluate the analgesic effect of intravenous tenoxicam (non-steroidal anti-inflammatory drug) in the treatment of biliary colic pain and compared with spasmolytics. Thirtytwo patients (26 women, 6 men, mean age 47, range 38-55 years) with acute biliary colic were entered for study. They were allocated randomly to receive either tenoxicam 20 mg i.v. or hyoscine N-butylbromide 20 mg i.v. The patients recorded their pain severity on 5 point scale. The results showed that tenoxicam caused significant pain relief in 10 out of 16 patients at 30 min (mean pain score decreased from 2.75 +/- 0.93 to 0.49 +/- 0.51, p < 0.05) and in other 4 patients at 60 min (mean pain score decreased to 0.58 + 5.7, p < 0.05). None of these patients developed acute cholecystitis or pain relapse over a period of 24 h follow up. With use of hyoscine N-butylbromide, 7 out 16 patients had significant pain relief at 30 min (mean pain score decreased from 2.62 +/- 1.01 to 0.57 +/- 0.53, p < 0.05) and 3 other patients relieved at 60 min (mean pain score decreased to 0.66 +/- 0.57, p < 0.05). Four patients showed pain relapse within 24 h and needed pethidine-rescue treatment, two of them developed acute cholecystitis. Three out of 6 patients who showed no response to hyoscine N-butylbropmide and treated with 100 mg pethidine progressed to acute cholecystitis. We concluded that intravenous tenoxicam has rapid and prolong analgesic effects in the treatment of acute biliary colic as compared to hyoscine N-butylbroimde and it prevents the progression to acute cholecystitis.

The diagnosis and treatment of biliary dyskinesia, defined as symptoms of biliary colic in the absence of gallstones, remains controversial and has been the subject of several previous retrospective reviews. The diagnosis and treatment of biliary dyskinesia based on the CCK-HIDA scan, and the outcome with cholecystectomy for billary dyskinesia, are reviewed. We add more than 200 cases of cholecystectomy for biliary dyskinesia, and compare our results with those of previous reports. We retrospectively reviewed 295 patients with biliary dyskinesia who underwent cholecystectomy at three military hospitals between 1988 and 1995. All patients had symptoms consistent with biliary colic and preoperative evaluations that revealed no evidence of cholelithiasis. Pathology specimens were reviewed for cholelithiasis and pathologic changes. Data were retrieved by chart review and clinic evaluation of new patients. Individual follow-up of each patient was attempted. Follow-up was achieved in 218 of the 295 patients for a rate of 74%. The mean duration of follow-up was 506 days with a range of 22 days to 6 years. Two hundred patients (92%) had CCK-HIDA scans with an ejection fraction (EF) >=<50%. Eighteen patients (8%) had an EF >50% but did have reproduction of their symptoms with CCK injection. In the group with an EF <50%, 94.5% were improved or cured with cholecystectomy. In the group with an EF >50% and pain reproduction, the improved or cured rate was 83.4%. CCK-HIDA scans are useful for diagnosing biliary dyskinesia and predicting improvement after cholecystectomy. Patients presenting with biliary dyskinesia and an EF <50% on CCK-HIDA scan have 94% improvement or resolution of their symptoms after cholecystectorny. CCK-HIDA scans should be employed early in the evaluation of billary colic with no evidence of cholelithiasis (i.e., with a normal ultrasound scan). When test results are abnormal, cholecystectomy should be performed, since the results in this setting approach those of cholecystectomy for stone disease (>90% cured/improved). In the current climate of cost containment, these excellent results would obviate the need for extensive and expensive medical testing before surgical therapy is recommended.

Over 500,000 patients undergo cholecystectomy annually in the United States for symptoms of upper abdominal discomfort and pain ascribed to gallbladder disease. However, approximately 5%, or 25,000 of these cases do not have gallstones on ultrasound examination but typically present with chronic symptoms of biliary colic. These patients often present as challenging diagnostic dilemmas and are often treated as if their symptoms are secondary to peptic ulcer disease or other gastrointestinal-related disorders. In 1992, we began to use the cholecystokinin (CCK) challenge test on patients with normal ultrasound examinations of the gallbladder but who had chronic symptoms resembling biliary colic. The CCK test was considered positive if the identical symptoms of discomfort or pain, usually in the right upper quadrant of the abdomen, were reproduced. This study describes the first 24 patients who had a positive CCK challenge test and chose to undergo cholecystectomy for relief of their symptoms. No patient was lost to follow-up evaluation at 1 to 24 months after operation.

Cholelithiasis leads to 80,000 cholecystectomies being performed every year in France, but its prevalence is still unknown. The aim of this study was to assess the prevalence and risk factors of cholelithiasis in a random population of 1027 women and 727 men over the age of 30 in a small town in the southeast of France. Detailed clinical history, dietary investigation, and gallbladder ultrasound were collected for each subject and assessed by univariate analysis. A regression model was used in the multivariate analysis to detect the relative risk of cholelithiasis. Cholelithiasis was found in 130 individuals (global prevalence 13.9%). The relative risk for lithiasis was higher in women compared to men (1.89). Age (P<0.0001) and body mass index (BMI) >25 (P = 0.013) were also significant risk factors. Neither pregnancy nor oral contraceptive use proved to be risk factors. Typical biliary colic pain was the only symptom significantly associated with cholelithiasis (P<0.0001). These results show that the prevalence of gallstones in France is similar to that in Denmark and Italy.
