Quantitative analysis of troponin I serum values in patients with acute cholecystitis

The diagnosis and staging of acute cholecystitis, upon a lot of diagnostic methods and some scoring systems, is still a great clinical problem. The aim of the study was to investigate if serum Troponin I is elevated in patients with acute cholecystitis. Following informed consent, 65 patients with clinical and laboratory signs of acute cholecystitis were enrolled. All patients had measured serum Troponin I level and an abdominal ultrasound was done before definitive treatment was performed. Increased serum Troponin I level was found in most patients with severe form of acute cholecystitis (p < 0.00001). It reached sensitivity of 94.5% and specificity of 57.1% of this test. In multiple regression analysis Troponin I significantly correlated (p < 0.05) with the serum aspartate aminotransferase (r = 0.27), gamma-glutamyl transferase (r = 0.25) and gallbladder wall (> 6 mm) thickness (r = 0.58). Our study confirms that in most patients with severe and acute cholecystitis, serum Troponin I is increased. Troponin I level is in a lower range than it would be in patients with cardiac muscle damage or necrosis. Measuring serum Troponin I is a fast, reliable and widely performed test that could, with other routinely measured parameters, help in early diagnosis of the severe form of acute cholecystitis.

Acute cholecystitis and thiazides.

Drugs purchased by a random sample (17 000) of the population of Jämtland county, Sweden, are continuously monitored. Patients who had been admitted to the county''s only hospital with acute cholecystitis and who were part of this sample were studied, and controls matched for age and sex were drawn from the sample. The purchase of thiazides and other drugs prescribed to the patients with acute cholecystitis was compared with that of the controls. The estimated relative risk of developing acute cholecystitis in patients who had purchased thiazides in the year before admission to hospital, as compared with those who had not, was 2.1 (95% confidence limit 1.1-3.9). As it has been reliably reported that the use of thiazides is not itself associated with cholelithiasis, the association found between thiazides and cholecystitis suggests that thiazides may increase the risk of acute cholecystitis developing in a patient with gall stones.     

Feasibility of breast conservation after neoadjuvant taxene based chemotherapy in locally advanced breast cancer: a Prospective Phase I trial

Background

Acute cholecystitis can be the result of retention of bile in the gallbladder with possible secondary infection and ischaemia. The aim of the present study was to investigate whether internal drainage of the gallbladder could protect against the development of acute cholecystitis in a pig model.

Materials and methods

Twenty pigs were randomized to either internal drainage (drained) or not (undrained). Day 0 acute cholecystitis was induced by ligation of the cystic artery and duct together with inoculation of bacteria. Four days later the pigs were killed and the gallbladders were removed and histologically scored for the presence of cholecystitis. Bile and blood samples were collected for bacterial culturing and biochemical analyses.

Results

The histological examination demonstrated statistical significant differences in acute cholecystitis development between groups, the degree of inflammation being highest in undrained pigs. There were no differences in bacterial cultures between the two groups.

Conclusion

Internal drainage of the gallbladder protected against the development of acute cholecystitis in the present pig model. These findings support the theory that gallstone impaction of the cystic duct plays a crucial role as a pathogenetic mechanism in the development of acute cholecystitis and suggest that internal drainage may be a way to prevent and treat acute cholecystitis.     

腹腔镜胆囊切除术治疗胆囊结石合并急性胆囊炎的疗效及对免疫功能和生活质量的影响

摘要 目的：观察腹腔镜胆囊切除术治疗胆囊结石合并急性胆囊炎的疗效及对免疫功能和生活质量的影响。方法：本次研究为回顾性研究,分析2018年3月~2021年3月期间我院收治的98例胆囊结石合并急性胆囊炎患者的临床资料,根据手术方案的不同将患者分为A组（n=46,给予开腹手术）和B组（n=52,给予腹腔镜胆囊切除术）,记录两组患者围术期相关指标、肝功能、免疫功能、生活质量和并发症发生率。结果：B组术中出血量少于A组,切口大小短于A组,手术时间长于A组,住院时间、首次排气时间短于A组（P<0.05）。两组术后3 d总胆红素 （TBIL）、谷丙转氨酶（ALT）、谷草转氨酶（AST）均升高,但B组低于A组（P<0.05）。B组术后3 d CD3⁺、CD4⁺、NK细胞、CD4⁺/CD8⁺高于A组（P<0.05）,B组术后3 d CD8⁺低于A组（P<0.05）。B组术后3个月健康生活量表简表（SF-36）各维度评分高于A组（P<0.05）。B组术后并发症发生率虽低于A组,但组间对比差异无统计学意义（P>0.05）。结论：腹腔镜胆囊切除术治疗胆囊结石合并急性胆囊炎,虽然手术时间较开腹手术更长,但切口小、可促进患者术后恢复,对患者免疫功能、肝功能损害更轻,有利于提高患者生活质量。     

Surgical Timing in Biliary Tract Disease

Based on 991 cases of biliary tract disease managed in a recent four-year period, the authors contrast an elective operative mortality rate of 0.6% against 4.4% for acute cholecystitis. Because in 21 of 28 patients with acute cholecystitis symptoms and signs subsided within 48 hours of conservative management in hospital, they recommend a two-day trial of conservative management for patients with acute cholecystitis and operation only for those who are not definitely improving under optimal conditions. The incidence and expected mortality from acute cholecystitis increased with age. Where possible, elective operation should be done when stones are first diagnosed because in patients over 65 years of age the rate of complications was four times and the mortality rate three times that in patients under 65. The incidence of cancer in cholelithiasis was sufficiently high that it is a significant factor in the consideration of prophylactic cholecystectomy. Patients with ruptured gall-bladders can present a trap for the unwary diagnostician; they should have minimal emergency surgery.     

Actue Cholecystitis Following Unrelated Surgery

In a series of 26 cases of acute cholecystitis occurring after an operation for an unrelated condition, 88% of the patients were over 50 years of age and males outnumbered females by 2 to 1. In some of the cases diagnosis was difficult and delay was responsible for the death of one patient. Acalculous cholecystitis occurred in 20% of the cases and in these gangrene or perforation supervened early in the course of the disease.Efforts should be directed to ensuring adequate hydration after operation; resumption of a diet low in fat may be important. Even in the absence of a history of biliary disease, there is a place for the radiological study of the biliary tract before major elective operations are performed. If gallstones are discovered on the occasion of the initial surgery, cholecystectomy should be performed whenever it is feasible. In any patient with postoperative cholecystitis early operation is generally indicated.     

Neutrophils injure gallbladder interstitial Cajal-like cells in a guinea pig model of acute cholecystitis

Acute cholecystitis is a common disease with gallbladder dysmotility. Disease pathogenesis involves immune cell infiltration as well as changes in gallbladder interstitial Cajal-like cells (ICLCs). However, it remains unclear if or how the immune cells affect ICLC morphology, density, distribution, and function in gallbladder tissue during acute cholecystitis. In this study, we explored the acute cholecystitis-related alterations in gallbladder ICLCs in a guinea pig model, focusing on the effects of neighboring neutrophils. Adult guinea pigs were randomly divided into four groups (control, 24 hr common bile duct ligation [CBDL], 48-hr CBDL, and antipolymorphonuclear neutrophil [PMN] treated) and analyzed using methylene blue staining and immunofluorescence. Gallbladder contractility was also monitored. To culture gallbladder ICLCs, collagenase digestion was performed on tissue from 10- to 15-day-old guinea pigs. Neutrophils isolated from the peripheral blood of experimental animals 48-hr postsurgery were also cocultured with the gallbladder ICLCs. Intracellular calcium was detected with Fluo-4 AM dye. Our results showed that gallbladder ICLC density significantly declined during acute cholecystitis and was accompanied by shortening of the cellular processes and damage to their network-like structure. However, pretreatment with anti-PMN partially prevented these changes. Gallbladder contraction was also significantly decreased during acute cholecystitis, and this appeared to be mediated by the neutrophils. Moreover, ICLCs cocultured with neutrophils also had shortened and reduced processes and impaired network-like structure formation. Intracellular calcium transient was less sensitive to contraction agonists and inhibitors when cocultured with neutrophils. Taken together, neutrophils greatly affect gallbladder ICLCs and dysmotility during acute cholecystitis.

Early cholecystectomy for acute cholecystitis

A series of 65 cases of acute cholecystitis from among 500 patients on whom cholecystectomy was performed by the author is presented. Early cholecystectomy was the operation of choice in 63 and cholecystostomy in two. The operative mortality for cholecystectomy was 1.6%; the postoperative morbidity was low and there were no serious complications such as common bile duct injury or biliary fistula. Operation for acute cholecystectomy is recommended within 48 hours of diagnosis to avoid serious complications such as perforation and suppurative cholangitis.     

The binding of microorganisms isolated from patients with complicated forms of acute cholecystitis with immobilized proteins in the bacterial sorption reaction

57 strains of different microbial species, isolated from patients having complicated forms of acute cholecystitis, were studied with the use of the reaction of bacteriosorption on immobilized proteins: fibrinogen, fibronectin, gamma globulin, ovalbumin, etc. The reaction of bacteriosorption was positive with all 4 Staphylococcus aureus strains: they were adsorbed on fibrinogen, fibronectin and gamma globulin. Besides, 4 out of 18 Staphylococcus epidermidis strains were selectively adsorbed on fibronectin and 1 of these strains was adsorbed on ovalbumin, while 2 out of 15 Escherichia coli strains were adsorbed on ovalbumin. S. epidermidis strains studied in this work differed from 15 strains of the same species, isolated from the urine of patients and studied earlier, by their adsorption properties.     

Staphylococcus aureus cholecystitis: a report of three cases with review of the literature

Infection of the hepatobiliary system is most commonly due to enteric bacteria. We report three unusual cases of acute cholecystitis in which Staphylococcus aureus was the primary pathogen. Infection of the gallbladder with this organism has been rarely described and may be associated with gallstones and obstructive disease as well as acalculous cholecystitis in the setting of staphylococcal bacteremia and endocarditis. Two of our patients had multiple chronic medical conditions and were infected with oxacillin-resistant S. aureus (ORSA) suggesting nosocomial acquisition. Including our cases with a review of the literature, three of nine reports of S. aureus cholecystitis were associated with infectious endocarditis. Thus, the finding of S. aureus cholecystitis with bacteremia is rare and should prompt an investigation for a possible endovascular focus of infection.     

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.     

RADIOGRAPHIC SIGNS OF ACUTE SUPPURATIVE CHOLECYSTITIS

In a recent series of 26 pathologically proven cases of acute cholecystitis, preoperative radiographic examination of the abdomen confirmed the presence of an inflammatory process in 17.The radiographic signs associated with acute suppurative cholecystitis are:1. Enlargement of the gallbladder, as indicated by separation or alteration in position of opaque calculi or indentation of adjacent bowel.2. Localized peritoneal irritation, manifested by (a) ileus of hepatic flexure of colon; (b) ileus of duodenal loop; (c) effacement of haustra of the hepatic flexure or valvulae conniventes of the duodenum; (d) obscuration of fat line marking inferior border of liver.3. Cholecystitis emphysematosa.4. Perforation of gallbladder, which if localized (retroperitoneal) is manifested by bubbles of gas in the gallbladder bed. If generalized (intraperitoneal) the signs are adynamic ileus of small and large bowel, increased intraperitoneal fluid, subdiaphragmatic abscess and plate atelectasis of right lung base.Visualization of the gallbladder and biliary tree after intravenous cholecystography rarely occurred in the presence of acute cholecystitis.Plain film examination of the abdomen aids in establishing the diagnosis of an acute cholecstitis and leads to the early recognition of complications such as perforation and peritonitis.     

Trends in management of acute cholecystitis.

A retrospective review has been carried out of the management of acute cholecystitis in one hospital from 1974 to 1978. The policies and outcome are compared with those of the same centre during 1953-62. In the intervening period there has been a move towards early cholecystectomy. Overall mortality has fallen from 7.7% to 1.6%. The results of early surgery are comparable with those of delayed operations. The data also compare favourably with those of controlled clinical trials and support the adoption of early cholecystectomy for acute cholecystitis in routine practice. The saving of resources, however, may not be as great as is suggested by the results of clinical trials.     

Inhibition of barnacle cyprid settlement using low frequency and intensity ultrasound

Low frequency, low intensity ultrasound was demonstrated as an effective inhibitor of barnacle cyprid settlement. When the same substratum vibration amplitude (10.05 nm) and acoustic pressure (5 kPa) were applied, ultrasound at a frequency of 23?kHz significantly reduced cyprid settlement. The mechanism appeared to differ from the ultrasonic cavitation induced inhibition previously reported as no increased mortality was observed, and no change in the exploratory behaviour of cyprids was observed when they were exposed to this continuous ultrasonic irradiation regime. The application of ultrasound treatment in an intermittent mode of '5?min on and 20?min off' at 20-25?kHz and at the low intensity of 5?kPa produced the same effect as the continuous application of 23?kHz. This energy efficient approach to the use of low frequency, low intensity ultrasound may present a promising and efficient strategy regarding irradiation treatment for antifouling applications.
