Acute pain from biliary colic is a model of pathological pain suitable for pharmacological investigations. It has been found useful for assaying analgesic effect of a narcotic-type agent (pentazocine) and a non-narcotic drug (indoprofen), both given intravenously in a single dose. Differences in pain intensity scores assessed on a five-point scale were taken as measurement of the pain-relieving effect. Distribution-free methods were used to estimate the potency ratio of the tested drugs. The analgesic potency of indoprofen based both on total and peak effect was roughly one-tenth that of pentazocine on a weight-for-weight basis. No adverse reactions were associated with indoprofen and a few were found after pentazocine.

10 elderly patients suffering from chronic lithiasic cholecystitis presented sporadic attacks of angor during the digestion of rather abundant meals, associated or otherwise with biliary colic. A clinical study was carried out in order to throw light on the close dependence of pain attacks with cholecystic stress. Observations confirmed the possibility that the onset of angor is due to reflex coronary vasoconstriction induced through the sympathetic system by stimuli arising in the gall bladder. The hypothesis is advanced that coronary impairment, however slight, is necessary for such vasoconstriction to be possible. Attention is called to the syndromes insofar as removal of the irritation in the gall bladder is almost always followed by complete remission of the coronary phenomenology.

A cholecystokinin (CCK) test was performed on 13 female patients who were thought to be having attacks of gallbladder pain and in whom at least one cholecystogram had been normal. In 10 of these patients the CCK test was performed during the course of a repeat cholecystogram in order to assess the effect of CCK on gallbladder contraction. There was no constant relationship between a positive test and gallbladder contraction as measured radiographically. Cholecystectomy was undertaken in 9 patients and of these, 4 had been CCK positive, 4 had been CCK negative and 1 had reacted equivocally. None of the CCK positive patients had stones at operation, whereas 2 of the CCK negative patients had one or two small stones. In this small series cholecystectomy relieved both the CCK negative and CCK positive patients of pain with equal frequency. It is concluded that a negative CCK test by no means excludes the presence of symptomatic gallstones in patients with X-ray negative gallbladder pain.

Asymptomatic biliary lithiasis can be defined as biliary lithiasis having determined no complication and no episode of biliary pain. Biliary pain is a consequence of acute increase of pressure inside the biliary tract. The increased pressure is induced by a stone transiently obstructing the cystic duct or the Oddi sphincter. In most patients, the site of the pain is epigastric. The level of the pain is high. The duration of the episode of biliary pain is usually less than 5 hours. Abdominal pain having other characteristics, dyspepsia, and headache are not related to biliary lithiasis.

This study examined respiratory function and metabolic and subjective responses in patients undergoing laparoscopic (n = 10) and open (n = 11) cholecystectomy for chronic cholecystitis and biliary colic. Patient groups were matched for age, sex, weight and height. The duration of operation was similar in both groups. Respiratory function tests (vital capacity, forced expiratory volume in 1 s, peak flow and arterial blood gases), urinary cortisol, vanillylmandelic acid, metanephrines and nitrogen loss, serum complement component C3 and C-reactive protein (CRP), full blood count, erythrocyte sedimentation rate (ESR) and subjective responses as assessed on a pain analogue scale and by analgesic usage were determined for up to 48 h after surgery. Deterioration in perioperative respiratory function was significantly less for laparoscopic surgery. Arterial blood gas determinations indicated a greater perioperative decrease in arterial pH, with carbon dioxide retention in patients undergoing open cholecystectomy (P < 0.02), reflecting poorer respiratory performance. Hormonal profile changes demonstrated an increase in urinary vanillylmandelic acid in the laparoscopic cholecystectomy group (P < 0.04); no differences were detected in urinary cortisol, metanephrine or nitrogen excretion. Acute-phase responses were greatest in patients undergoing open cholecystectomy as determined by ESR and CRP level (P < 0.02 and P < 0.003, respectively). Pain and analgesic usage were significantly decreased in the laparoscopic cholecystectomy group (P < 0.0009) and P < 0.0001), which led to a decreased hospital stay after operation in these patients (P < 0.0001). These data indicate improved respiratory and subjective responses and diminished acute-phase responses associated with laparoscopic surgery. Catabolic hormone release may, however, be increased.

Sixty consecutive patients underwent an elective attempt at laparoscopic cholecystectomy between March 15 and July 31, 1990 at the Mount Sinai Hospital in New York. Fifty-two patients had successful completion of the laparoscopic cholecystectomy (87%). The reasons for conversion to open cholecystectomy were acute cholecystitis (four patients), inability to define the cystic duct-common duct junction (three patients), and one patient with an unexpected choledochal cyst variant. Forty patients (77%) were discharged on the first post-operative day, and the remaining 12 patients on the second post-operative day. Thirty-three patients (63%) required only oral pain medication, and 11 patients (21%) needed no pain medication post-operatively. Fifty-one patients (98%) had resumed normal activities by the seventh post-operative day. Cholecystectomy remains the treatment of choice for biliary colic. Laparoscopic cholecystectomy minimizes length of stay in the hospital, lessens post-operative pain, allows quicker return to normal activities, and has a superior cosmetic result.

Prostaglandins GE2 produces on the gallbladder a rise in intraluminal pressure, an increase in in intraluminal secretion, improves gallbladder contraction and decreases its absorption capacity. In this study, patients who received indomethacin twice a day by rectum, showed a significant reduction in volume and area of gallbladder after 24 and 48 hours (P < 0.05). The gallbladder volume after 24 hours had SEM 9.13 cm3, 95% CI 55.28 + 73.49 (P < 0.05). Score pain reduction after 24 hours was also significant (P < 0.001). The patients who underwent the classical Baralcina treatment of one IV vial BID showed a reduction in diameter and area of gallbladder but this was not statistically significant (P < 0.10). Reduction of volume at 24 hours was SEM 5.34 cm3 95% CI - 64.72 + 76.60 P 0.10 NS; and at 48 hours SEM 3.5 cm3, 95% CI 59.52% + 66.52 P 0.40. Score pain reduction was only significant at 48 hours P 0.001. The number of patients without pain at 24 hours was significantly higher in the indomethacin group ESP 0.21; 95% CI 0.46 + 0.88 P 0.001. In conclusion indomethacin is a useful medication in the treatment of acute cholecystitis and biliary colic due to its anti-prostaglandin effect on the gallbladder.

Gallstones are very common, but at least two thirds of detected stones are asymptomatic and a large number undoubtedly go undetected. The presence of symptoms or complications is the indication for surgery. It is important to accurately identify which symptoms are caused by gallstones, because removing the gallbladder will relieve only these symptoms. Making this determination is a challenge, however, because the classic picture of biliary colic may be inaccurate and the connection between gallstone disease and flatulent dyspepsia is questionable at best. Descriptions of both these conditions are based on anecdotal evidence or reports of uncontrolled surgical series. A review of recent controlled trials suggests that the pain of biliary colic is constant and infrequent, comes in episodes lasting 1 to 5 hours, is located in the epigastrium or right upper quadrant of the abdomen, and characteristically occurs at night. There are few additional symptoms other than nausea or vomiting, and colic is not induced by eating fatty meals. Flatulent dyspepsia--a symptom complex of vague pain in the right upper quadrant, fatty-food intolerance, and bloating--is probably not related to the presence of gallstones in the majority of patients.

Biliary pain without obvious biliary obstruction is common in postcholecystectomy patients. We studied 20 symptomatic patients with episodes of biliary-type pain after cholecystectomy (all having undergone endoscopic retrograde cholangiography), and in 18 asymptomatic postcholecystectomy controls. We performed quantitative hepatobiliary radionuclide analysis with dimethyl-imidodiacetic acid. From a series of 90 dynamic images at 1-min intervals using a gamma camera coupled to a computer, time-activity curves were produced in regions of interest in the liver, intrahepatic biliary tree, common duct, and heart, from which quantitative biliary excretion indexes were obtained. The results demonstrate a biliary kinetic dysfunction in patients with postcholecystectomy pain without morphological abnormalities.

To assess the possibility of common bile duct distensibility after cholecystectomy, we made a retrospective study of patients who had ultrasonography and endoscopic retrograde cholangiopancreatography (ERCP). The study comprised 52 patients without extrahepatic biliary obstruction; 19 had had cholecystectomy, 18 of whom complained of biliary colic similar to that they had had originally. The other 33 patients had intact, well visualized gallbladders; 15 of these patients had pain in the right upper quadrant or epigastrium, but none had chronic pancreatitis. The average diameter of the common bile duct at its widest point by ultrasonography was 4.8 mm (range, 4.0 to 9.0 mm) in the 33 patients with intact gallbladders, and 5.7 mm (range, 4.0 to 8.0 mm) in the 19 patients who had had cholecystectomy. The diameter by ERCP was 4.4 mm (range, 2.9 to 6.3 mm) in the patients with intact gallbladders, and 11.17 mm (range, 6.9 to 14.7 mm) in the patients who had had cholecystectomy. In each patient who had had cholecystectomy the diameter as measured by ERCP was larger than it appeared by ultrasonography. The results suggest that the common bile duct is distensible, and that this distensibility may be related to the postcholecystectomy syndrome.
