Cholescintigraphy in patients with acute cholecystitis before and after percutaneous gallbladder drainage.

OBJECTIVE: To investigate gallbladder function by use of cholescintigraphy in patients with acute cholecystitis before and after percutaneous gallbladder drainage. DESIGN: A cholescintigraphy was performed in 40 patients with acute cholecystitis before and after the performance of percutaneous gallbladder drainage. During the post-drainage cholescintigraphies, a cholecystokinin stimulation was performed to investigate gallbladder emptying in 12 selected patients. Gallbladder pressure and volume were measured before drainage in another group of 12 patients with acute cholecystitis. RESULTS: As expected, no gallbladder activity was observed in the cholescintigraphies before drainage, except in a patient with an occluding stone in the common bile duct. Cystic duct patency and gallbladder activity were seen in 80% of patients in cholescintigraphies performed after drainage but before any other treatment. Post-drainage cholescintigraphy revealed a mean gallbladder ejection fraction of 24%, which is significantly lower than the corresponding value in normal individuals and gallstone patients without cholecystitis (n = 12). Gallbladder pressure and volume were markedly increased compared with normal values. CONCLUSION: The relief of increased gallbladder pressure and volume appears to be important for the re-establishment of gallbladder function.

Acute granulomatous schistosomal cholecystitis.

Schistosomal cholecystitis is a rare entity with less than 10 cases described in the medical literature [1-3]. It is unclear whether schistosomal eggs deposited in the wall of the gallbladder trigger a clinically manifest acute cholecystitis, since most of the cases described were also found to have concomitant gallstones. Herein, we report a patient who developed acute schistosomal granulomatous acalculous cholecystitis. The clinical presentation, chronology of events and pathological findings strongly support the association between cholecystitis and schistosomal infection.

Prospective evaluation of emergency versus delayed laparoscopic cholecystectomy for early cholecystitis.

Treatment of acute cholecystitis is still under debate. The aim of this study was to evaluate the efficacy of early laparoscopic cholecystectomy (ELC) in comparison with conservative treatment followed by delayed laparoscopic cholecystectomy (DLC) in the management of acute cholecystitis. This prospective comparative study involved two groups of patients presenting with acute cholecystitis within 72 hours of the onset of symptoms. ELC was performed in 82 consecutive patients, whereas DLC was performed in 87 patients who previously underwent medical treatment. Surgical variables, hospital stay, and postoperative morbidity were evaluated in both groups. Time of surgery and conversion rate were lower in the ELC group. Postoperative morbidity was similar in both groups. Overall hospital stay was shorter in the ELC group. ELC within 72 hours of the onset of acute cholecystitis is a safe procedure with better results than DLC in terms of surgical timing, conversion rate, and hospital stay.

Ischaemic cholecystitis and infarction of the gallbladder.

The clinicopathological features of forty three patients with gallbladder disease are presented where ischaemia appeared to be the primary aetiological factor. Histopathological changes of severe ischaemia (ischaemic cholecystitis) were present in 16 patients and of infarction of the gallbladder in the remaining 27 patients. All patients with ischaemic cholecystitis and 19 of the patients with infarction of the gallbladder had a thick walled gallbladder due to a serosal reaction, and these 35 gallbladders all contained calculi. The remaining eight patients with infarction of the gallbladder had a thin walled gallbladder without serosal reaction. Only two of these patients had gallbladders that contained calculi. The pathogenesis of thick walled ischaemic cholecystitis or infarction appeared to be related to intramural vascular insufficiency which accompanies calculus disease of the gallbladder. Thin walled infarction of the gallbladder appeared to develop as a result of extramural arterial insufficiency due to arterial disease, thrombosis or trauma. The clinical course of thick walled ischaemic gallbladder disease was not significantly different from severe acute cholecystitis with calculi. However, 75% of the patients with thin walled infarcted gallbladders were severely ill from their associated illness or trauma, and nearly all died.

Radionuclide scanning for the rapid diagnosis of acute cholecystitis.

Radionuclide scanning with Technetium 99-m HIDA was performed in eighty-nine patients with suspected acute cholecystitis. In twenty-three patients (25.8%), the study demonstrated evidence of cystic duct obstruction and non-visualisation of the gallbladder. Almost all of these patients subsequently were shown to have acute cholecystitis at surgery. The sensitivity and specificity of the procedure for the diagnosis of acute cholecystitis was 95.8% and 100% respectively. The use of radionuclide cholescintigraphy in the assessment of hepatobiliary disorders is reviewed, and it is suggested that it is the test of choice at present for diagnosis of acute cholecystitis.

Emergency department evaluation of geriatric patients with acute cholecystitis.

OBJECTIVE: To estimate the frequency of abnormal clinical symptoms, laboratory tests, and diagnostic imaging studies in the ED assessment of elderly (> or = 65 yr) patients with acute cholecystitis, and to compare these factors in young-old (65-74 yr), middle-old (75-84 yr), and old-old (> or = 85 yr) population groups. METHODS: A retrospective, cross-sectional study was performed by review of ED records, hospital charts, and surgical operative reports of consecutive elderly ED patients determined at surgery to have acute cholecystitis. Records were reviewed between April 1990 and April 1995 at a large Midwestern tertiary care facility with 65,000 annual ED patient visits. Clinical signs and symptoms were compared in the young-old, middle-old, and old-old population groups. RESULTS: Of the 168 patients reviewed, 141 (84%) had neither epigastric or right upper quadrant abdominal pain, and 8 (5%) had no pain whatsoever. Only 61 patients (36%) had back or flank pain radiation. Ninety-six (57%) experienced nausea, 64 (38%) had emesis, and 13 (8%) had visible jaundice. Ninety-four (56%) patients were afebrile and 69 (41%) had no increase of white blood cell count. Twenty-two (13%) patients had no fever and all tests were normal. No statistical difference was noted in any symptom or laboratory factor for the 3 age groups, except jaundice was more common among the patients aged > or = 85 years. Ultrasonography was diagnostic for 91%, and CT was beneficial for only 1 patient. Eight patients had normal results on their ultrasonographic and CT studies. CONCLUSION: Classic symptoms and abnormal blood test results are frequently not present in geriatric patients with acute cholecystitis. Increasing age does not appear to affect the clinical and test markers used by clinicians to diagnose this illness. A high degree of awareness is essential for correct diagnosis of acute cholecystitis in geriatric patients.

Laparoscopic cholecystectomy as a safe and effective treatment for severe acute cholecystitis.

OBJECTIVE: To evaluate the feasibility and safety of laparoscopic cholecystectomy in severe acute cholecystitis. DESIGN: Analysis of data collected prospectively from a consecutive series of 350 laparoscopic operations. SETTING: Two general surgical units in a teaching hospital. SUBJECTS: 31 patients with a diagnosis of severe acute cholecystitis based on clinical examination, investigation results, and operative findings. INTERVENTIONS: Initial intravenous fluids and broad spectrum antibiotics followed by laparoscopic cholecystectomy within 72 hours of presentation. MAIN OUTCOME MEASURES: Failure to complete the operation laparoscopically, length of postoperative stay in hospital, early postoperative morbidity, interval from operation to full activity, and return to work. RESULTS: Laparoscopic cholecystectomy was attempted in 19 patients with empyema of the gall bladder and 12 who had severe cholecystitis which failed to settle on medical management. A total of 29 operations were successfully completed with two conversions to open surgery. Two minor postoperative complications occurred, and one case of retained common bile duct stones with jaundice was treated by endoscopic retrograde cholangiopancreatography and papillotomy. Median postoperative hospital stay was two days, with return to normal activity in seven days and to work in two weeks. There were no deaths related to the operation. CONCLUSIONS: In the presence of severe acute cholecystitis laparoscopic cholecystectomy is feasible in most patients, with minimal risk of injury to surrounding structures and considerable benefits. It is recommended that laparoscopic cholecystectomy should be attempted in these patients when appropriate surgical skill is available.

Liver changes associated with cholecystitis.

AIMS: To investigate the histopathological changes in the livers of patients undergoing cholecystectomy and to relate these changes to the underlying biliary tract pathology. METHODS: Liver changes in 67 patients undergoing cholecystectomy were investigated. Sixty three had gall stones, one cholesterolosis only, and there were three cases of acute acalculous cholecystitis. RESULTS: Only 34% of the patients had completely normal liver biopsy specimens. The most clinically important pathology was found in 11 of the 14 patients with choledocholithiasis: three of these had cholangitis and eight had features of large bile duct obstruction (four also had chronic cholestasis and portal-portal linking fibrosis). Non-specific reactive hepatitis was the most common abnormality in the remaining 53 patients with cholecystitis alone, and was found in 18. A further four patients had chronic cholestasis without fibrosis and early primary biliary cirrhosis was a coincidental finding in another. Clinical symptoms were poorly correlated with gall bladder and liver pathology apart from an association between jaundice and choledocholithiasis. Liver function tests of obstructive pattern were noted in 23 of 58 patients, most of whom had choledocholithiasis or non-specific reactive hepatitis. Bile cultures were positive in 10 of 42 patients, predominantly in cases of cholangitis and acute cholecystitis. CONCLUSIONS: Cholangitis and extensive fibrosis associated with large bile duct obstruction are common findings in patients with choledocholithiasis. The liver disease may progress to secondary biliary cirrhosis if the obstruction is not relieved, emphasising the need for early surgery. A peroperative liver biopsy may be useful to exclude cirrhosis in these patients, but is unlikely to be informative in those with cholecystitis alone.

Management of acute cholecystitis in UK hospitals: time for a change.

Early cholecystectomy for patients with acute cholecystitis is safe, cost effective, and leads to less time off work compared with delayed surgery. This study was designed to assess current practice in the management of acute cholecystitis in the UK. A postal questionnaire was sent to 440 consultant general surgeons to ascertain their current management of patients with acute cholecystitis. Replies were received from 308 consultants who were involved in treating patients with acute cholecystitis of whom 18 transferred these patients on to another team for further management the day after admission. Thirty two consultants (11%) routinely treated patients by early cholecystectomy, with limiting factors stated to be the availability of surgical staff, theatre space, and radiological investigations. The remaining consultants (n = 258) routinely manage their patients conservatively with intravenous antibiotics and allow the inflammation to resolve before undertaking cholecystectomy at a later date. Indications for undertaking early cholecystectomy during the first admission by this latter group included the presence of spreading peritonitis due to bile leak, empyema, and unexpected space on theatre list. The commonest method for both elective and early cholecystectomy is laparoscopic, but the percentage of consultants using an open method rises from 8% in the elective situation to 47% for urgent early cholecystectomy. Despite evidence which strongly advocates early cholecystectomy, this practice is routinely carried out by only 11% of consultants in the UK at present.

Gangrenous cholecystitis: diagnosis by ultrasound.

Sonographic findings were analyzed in 19 patients with surgically proved gangrenous cholecystitis. In 8 patients (42%), there were no specific features that would allow differentiation from typical uncomplicated acute cholecystitis. However, in 11 patients (58%) atypical findings were present, including intraluminal membranes and/or marked irregularities of the gallbladder wall. These features are unusual in uncomplicated acute cholecystitis and should prompt close clinical observation for possible gangrenous cholecystitis.

Acute cholecystitis: comparison of MR cholangiography and US.

PURPOSE: To evaluate the clinical usefulness of magnetic resonance (MR) cholangiography in the assessment of acute cholecystitis by comparing the diagnostic accuracy of MR cholangiography with that of ultrasonography (US). MATERIALS AND METHODS: Thirty-five patients with symptoms of acute cholecystitis underwent both US and MR cholangiography before cholecystectomy, which helped confirm acute cholecystitis. Two reviewers evaluated US and MR cholangiographic images for evidence of calculi and gallbladder wall thickening and compared these findings with surgical findings. RESULTS: MR cholangiography depicted all 21 (100%) calculi and one false-positive calculus in the cystic duct and gallbladder neck, but US depicted only one (14%) of seven cystic duct calculi and 12 (86%) of 14 gallbladder neck calculi. In the diagnosis of cystic duct obstruction, MR cholangiography had a sensitivity of 100%, a specificity of 93%, and an accuracy of 97%. US had a sensitivity of 62%, a specificity of 100%, and an accuracy of 77%. In the diagnosis of gallbladder wall thickening, MR cholangiography had a sensitivity of 69%, a specificity of 83%, and an accuracy of 71%. US had a sensitivity of 96%, a specificity of 83%, and an accuracy of 94%. CONCLUSION: In the assessment of acute cholecystitis, US is superior to MR cholangiography in the evaluation of gallbladder wall thickening. However, MR cholangiography is superior to US in the depiction of cystic duct and gallbladder neck calculi at the evaluation of cystic duct obstruction.

Percutaneous aspiration, lavage and antibiotic instillation. New approach in the management of acute calculous cholecystitis.

Distension of the gallbladder and bacterial infection can perpetuate an attack of acute calculous cholecystitis and produce its local and systemic complications. This prospective randomized trial was conducted on patients with their first episode of acute calculous cholecystitis which was associated with pyrexia and tachycardia to examine whether ultrasound guided percutaneous aspiration and lavage of the gallbladder followed by intra-lumenal instillation of 500 mg ampicillin (PALA) enhanced recovery from cholecystitis. Twenty patients were randomized to receive 500 mg of ampicillin every 6 hours for 5 days and another 20 patients were randomized to receive this treatment in addition to PALA within 12 hours of admission. Twenty four hours after admission to hospital, all the patients treated with PALA were apyrexial and had no residual right hypochondrial tenderness or guarding, a result superior (p less than 0.001) to that of the group without PALA where at least 75% of patients were still showing these signs. Two days after admission the WBC count of the PALA group was significantly (p less than 0.05) lower than that of the other group (6.32 +/- 0.1 x 10(9)/L vs 10.31 +/- 0.4 x 10(9)/L, mean +/- SEM, n = 20). Four days after admission, all members of the PALA group were comfortably tolerating solid food for the previous 24 hours and were, therefore, discharged home whereas all members of the other group were still in hospital and 85% of them were discharged home after hospitalization for 6 to 7 days. Three members (15%) of this group deteriorated and underwent emergency surgery. The results show that addition of PALA to the conventional non-operative treatment of acute cholecystitis enhances recovery and avoids the complications necessitating emergency surgery.

Acute acalculous cholecystitis in systemic lupus erythematosus: a case report and review of the literature.

A 27-year-old woman with systemic lupus erythematosus (SLE) was found to have acute acalculous cholecystitis. At the time of admission, the patient was not under corticosteroid or immunosuppressive therapy. Computed tomography (CT) and ultrasonography revealed findings in the gall bladder consistent with acute acalculous cholecystitis. Her abdominal pain completely disappeared following corticosteroid therapy, with dramatic improvement in the images of CT and ultrasonography. Six similar cases of SLE complicated with acute acalculous cholecystitis have been reported in the literature and they were all treated surgically by cholecystectomy or cholecystostomy. This is the first case report in which acute acalculous cholecystitis accompanying SLE was treated successfully by corticosteroid without surgical intervention.

Microsatellite instability in chronic cholecystitis is indicative of an early stage in gallbladder carcinogenesis.

The study of microsatellite instability (MSI) in cases of severe chronic cholecystitis and gallbladder carcinomas, to cast light on its significance for tumorigenesis, revealed MSI in 9 (30%) of 30 cases of cholecystitis and 7 (41%) of 17 carcinomas, respectively. In addition, 5 (33%) of 15 samples of background mucosa of carcinoma were positive. Respective figures for loss of heterozygosity were 3 (10%) of 30 cases of cholecystitis, 6 (35%) of 17 carcinomas, and 1 (7%) of 15 samples of adjacent nonneoplastic mucosa. No correlation was observed among MSI state, immunohistochemical hMLH1 or hMSH2 expression, and any clinicopathologic factors. MSI was observed not only in gallbladder tumors but also in severe chronic cholecystitis and background mucosa, suggesting that it may have an important role in early-stage gallbladder carcinogenesis.

Rapid and accurate diagnosis of acute cholecystitis with 99mTc-HIDA cholescintigraphy.

Technetium-99m dimethyl acetanilide iminodiacetic acid (HIDA) cholescintigraphy was performed on 90 patients with suspected acute cholecystitis. Visualization of the gallbladder established patency of the cystic duct and excluded the diagnosis of acute cholecystitis in 50 of 52 patients. Nonvisualization of the gallbladder with visualization of the common bile duct was diagnostic of acute cholecystitis in 38 patients, all subsequently proven at surgery. The observed accuracy of this procedure is 98% and specificity is 100%. The false negative rate is 5% and false positive rate is zero. Technetium-99m-HIDA has many advantages which make it the procedure of choice in evaluating a patient for suspected acute cholecystitis. It is a rapid, simple, safe examination which provides functional as well as anatomic information about the hepatobiliary system in individuals with a serum bilirubin level up to 8 mg/100 ml.

PIPIDA scintigraphy for cholecystitis: false positives in alcoholism and total parenteral nutrition.

A review of gallbladder scintigraphy in patients with potentially compromised hepatobiliary function revealed two groups in whom cholecystitis might be mistakenly diagnosed. In 200 consecutive hospitalized patients studied with technetium-99m-PIPIDA for acute cholecystitis or cholestasis, there were 41 alcoholics and 17 patients on total parenteral nutrition. In 60% of the alcoholics and 92% of those on parenteral nutrition, absent or delayed visualization of the gallbladder occurred without physical or clinical evidence of cholecystitis. A cholecystagogue, sincalide, did not prevent the false-positive features which presumably are due to altered bile flow kinetics related to alcoholism and parenteral nutrition. Four patients on parenteral nutrition undergoing cholecystectomy for suspected cholecystitis had normal gallbladders filled with jellylike viscous thick bile. A positive (nonvisualized or delayed visualized) gallbladder PIPIDA scintigram in these two populations should not be interpreted as indicating a need for cholecystectomy.

The sonographic diagnosis of acute gangrenous cholecystitis: importance of the Murphy sign.

The sonographic Murphy sign is defined as the presence of maximal tenderness elicited by direct pressure of the transducer over a sonographically localized gallbladder. The reported prevalence of this sign is more than 95% in patients with acute cholecystitis. In this series of 18 patients with pathologically proved gangrenous cholecystitis, the sonographic Murphy sign was positive in only six (33%). Clinical examination showed a positive Murphy sign in eight patients (44%), diffuse abdominal pain in nine patients (50%), and no pain in one patient (6%). Other sonographic findings included pericholecystic fluid (10), thickening of the gallbladder wall (10), and a dilated gallbladder (five). Our experience suggests that the absence of the Murphy sign increases the possibility of gangrenous cholecystitis in patients with abdominal pain and sonographic findings of cholecystitis.

CT finding of transient focal increased attenuation of the liver adjacent to the gallbladder in acute cholecystitis.

OBJECTIVE: The purpose of this article is to report the finding of transient focal increased attenuation of the liver adjacent to the gallbladder on enhanced CT scans in patients with acute cholecystitis. This finding should not be confused with primary liver abnormalities. MATERIALS AND METHODS: Five patients with acute cholecystitis were studied. Because a thickened gallbladder wall was seen on sonography, all patients were examined preoperatively with incremental dynamic helical CT to exclude carcinoma of the gallbladder. CT findings were compared with results of sonography for five patients, MR imaging for two patients, and surgery for five patients. RESULTS: Transient focal increased attenuation of the liver adjacent to the gallbladder was seen in the early phase of incremental dynamic CT in five patients and extended into the medial segment anterior to the porta hepatis. The areas showing increased attenuation adjacent to the gallbladder had a curvilinear shape around the gallbladder. No hepatic masses were seen on sonograms, on MR images, or at surgery. CONCLUSION: Transient focal increased attenuation of the liver may occur on CT scans in patients with acute cholecystitis. The increased attenuation associated with acute cholecystitis has a typical location and pattern. This finding is probably attributable to hepatic arterial hyperemia and to early venous drainage caused by the adjacent inflamed gallbladder. This finding should be differentiated from hypervascular hepatic tumors.
