Patient outcomes after treatment with percutaneous cholecystostomy for biliary sepsis

INTRODUCTION

Acute cholecystitis is among the most common general surgical presentations. There is a cohort of patients who develop systemic sepsis and complications of acute cholecystitis. These patients are often elderly and co-morbid. Conservative management with percutaneous cholecystostomy has been shown to be a safe and effective management option in the acute setting. However, there is currently no consensus for the further management of these patients. In particular, there is a paucity of data on readmission rates and subsequent operative or non-operative management.

METHODS

A retrospective study was carried out of patients treated with a percutaneous cholecystostomy for biliary sepsis over a three-year period in a UK teaching hospital. Outcome measures were subsequent operative or conservative management, conversion rates, operative complications and readmission rates.

RESULTS

Twenty-five patients had a percutaneous cholecystostomy for the treatment of acute biliary sepsis. The median follow-up duration was 35 months. Thirteen patients (52%) had operative treatment. In the operative group, 6/13 had a laparoscopic cholecystectomy, 2/13 had a planned open cholecystectomy, 2/13 had abandoned procedures and 3/13 had a converted procedure. Complications in the operative group included: postoperative mortality (1/13), common bile duct injury requiring drainage and endoscopic stenting (1/13) and one patient required readmission with recurrent pain. In the non-operative group, 5/12 patients were readmitted with biliary sepsis, 5/12 had no readmissions, 1/12 died in the community and 1/12 was readmitted with biliary colic.

CONCLUSIONS

Percutaneous cholecystostomy is a recognised treatment modality for elderly, co-morbid patients with biliary sepsis. Nevertheless, the readmission rate in this group is relatively high at 5/12 (42%). Patients who undergo subsequent operative management have a conversion rate of 3/13 (23%) and a significant complication rate of 2/13 (15%). The further management of patients having undergone percutaneous cholecystostomy requires careful consideration on an individual case basis. The P-POSSUM (Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity) may aid decision making.

Ultrasound-guided double-tract percutaneous cholecystostomy combined with a choledochoscope for performing cholecystolithotomies in high-risk surgical patients

BACKGROUND

Cholecystolithiasis is the most common disease treated by general surgery, with an incidence of about 0.15-0.22%. The most common therapies are open cholecystectomy (OC) or laparoscopic cholecystectomy (LC). However, with a greater understanding of the function of the cholecyst, more and more patients and surgeons are aware that preserving the functional cholecyst is important for young patients, as well as patients who would not tolerate anesthesia associated with either OC or LC. Based on these considerations, we have introduced a notable, minimally invasive treatment for cholecystolithotomy.

METHODS

We performed a retrospective review of patients with cholecystolithiasis who were unable to tolerate surgery or who insisted on preserving the functional cholecyst. Our particular approach can be simply described as ultrasound-guided percutaneous cholecystostomy combined with a choledochoscope for performing a cholecystolithotomy under local anesthesia.

RESULTS

Ten patients with cholecystolithiasis were treated via this approach. All except one patient had their gallbladder stones totally removed under local anesthesia, without the aggressive procedures associated with OC or LC. The maximum number of gallbladder stones removed was 16, and the maximum diameter was 13 mm without lithotripsy. After the minimally invasive surgery, the cholecyst contractile functions of all patients were normal, confirmed via ultrasound after a high-fat diet. Complications such as bile duct injury, biliary fistula, and bleeding occurred significantly less often than with OC and LC. The recurrence rates for each of 2 post-operative years were about 11.11% (1/9, excluding a failure case) with uncertainty surrounding recurrence or residue, and 22.22% (2/9, including one non-recurrence patient with follow-up time of 22 months), respectively.

CONCLUSIONS

Ultrasound-guided percutaneous cholecystostomy combined with choledochoscope is a safe, efficient, and minimally invasive cholecystolithotomy method. We recommend this technique for the management of small stones (less than 15 mm) in high-risk surgical patients.

[Mini-invasive technologies in treatment of acute cholecystitis in patients with high operational and anesthetic risk]

The treatment results of 769 patients with acute calculous cholecystitis and high operational and anesthetic risk at admission are presented in the retrospective study. High risk was determined by expressed comorbidities, diseases' terms, the complications of acute cholecystitis, age, which was more than 60 years in most cases. The patients were divided into 2 groups depending on the severity of comorbidity and the possible effects of its correction. The first group included 617 perspective patients for cholecystectomy. And the second group included 152 patients unpromising for this. Concept of stage treatment was used in the first group including primary decompression of the gallbladder by using of percutaneous transhepatic micro-cholecystostomy under ultrasound guidance. Cholecystectomy was performed after correction of comorbidities, complications of acute cholecystitis, and readjustment of extrahepatic bile ducts by endoscopy if necessary. Laparoscopic cholecystectomy was successfully performed in 587 patients. There was open cholecystectomy in 11 cases. Cholecystectomy was done in 19 patients as a result of conversion. Cholecystostomy from minimal access with extraction of stones under local anesthesia was performed in the second group for decompression and as definitive treatment. There was not observed deaths in patients with high operational and anesthetic risk as a result of such tactics. Postoperatively 1.7% of patients had complications that were successfully resolved.

Percutaneous cholecystostomy for high-risk surgical patients with acute calculous cholecystitis

BACKGROUND

The management of people at high risk of perioperative death due to their general condition (high-risk surgical patients) with acute calculous cholecystitis is controversial, with no clear guidelines. In particular, the role of percutaneous cholecystostomy in these patients has not been defined.

OBJECTIVES

To compare the benefits (temporary or permanent relief of symptoms) and harms (recurrence of symptoms, procedure-related morbidity) of percutaneous cholecystostomy in the management of high-risk individuals with symptomatic gallstones.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded to December 2012 to identify the randomised clinical trials. We also handsearched the references lists of identified trials.

SELECTION CRITERIA

We included only randomised clinical trials (irrespective of language, blinding, or publication status) addressing this issue.

DATA COLLECTION AND ANALYSIS

Two review authors collected data independently. For each outcome, we calculated the P values using Fisher's exact test or mean difference (MD) with 95% confidence intervals (CI).

MAIN RESULTS

We included two trials with 156 participants for this review. The comparisons included in these two trials were percutaneous cholecystostomy followed by early laparoscopic cholecystectomy versus delayed laparoscopic cholecystectomy (1 trial; 70 participants) and percutaneous cholecystostomy versus conservative treatment (1 trial; 86 participants). Both trials had high risk of bias. Percutaneous cholecystostomy with early laparoscopic cholecystectomy versus delayed laparoscopic cholecystectomy: There was no significant difference in mortality between the two intervention groups (0/37 versus 1/33; Fisher's exact test: P value = 0.47). There was no significant difference in overall morbidity between the two intervention groups (1/31 versus 2/30; Fisher's exact test: P value = 0.61). This trial did not report on quality of life. There was no significant difference in the proportion of participants requiring conversion to open cholecystectomy between the two intervention groups (2/31 percutaneous cholecystostomy followed by early laparoscopic cholecystectomy versus 4/30 delayed laparoscopic cholecystectomy; Fisher's exact test: P value = 0.43). The mean total hospital stay was significantly lower in the percutaneous cholecystostomy followed by early laparoscopic cholecystectomy group compared with the delayed laparoscopic cholecystectomy group (1 trial; 61 participants; MD -9.90 days; 95% CI -12.31 to -7.49). The mean total costs were significantly lower in the percutaneous cholecystostomy followed by early laparoscopic cholecystectomy group compared with the delayed laparoscopic cholecystectomy group (1 trial; 61 participants; MD -1123.00 USD; 95% CI -1336.60 to -909.40). Percutaneous cholecystostomy versus conservative treatment: Nine of the 44 participants underwent delayed cholecystectomy in the percutaneous cholecystostomy group. Seven of the 42 participants underwent delayed cholecystectomy in the conservative treatment group. There was no significant difference in mortality between the two intervention groups (6/44 versus 7/42; Fisher's exact test: P value = 0.77). There was no significant difference in overall morbidity between the two intervention groups (6/44 versus 3/42; Fisher's exact test: P value = 0.49). The number of participants who underwent laparoscopic cholecystectomy was not reported in this trial. Therefore, we were unable to calculate the proportion of participants who underwent conversion to open cholecystectomy. The other outcomes, total hospital stay, quality of life, and total costs, were not reported in this trial.

AUTHORS' CONCLUSIONS

Based on the current available evidence from randomised clinical trials, we are unable to determine the role of percutaneous cholecystostomy in the clinical management of high-risk surgical patients with acute cholecystitis. There is a need for adequately powered randomised clinical trials of low risk of bias on this issue.

Percutaneous cholecystostomy: the radiologist's role in treating acute cholecystitis

Acute cholecystitis is a common condition, with laparoscopic cholecystectomy considered the gold-standard for surgical management. However, surgical options are often unfavourable in patients who are very unwell, or have numerous medical co-morbidities, in which the mortality rates are significant. Percutaneous cholecystostomy (PC) is an image-guided intervention, used to decompress the gallbladder, reducing patient's symptoms and the systemic inflammatory response. PC has been shown to be beneficial in high-risk patient groups, predominantly as a bridging therapy; allowing safer elective cholecystectomy once the patient has recovered from the acute illness; or, in the minority, as a definitive treatment in patients deemed unfit for surgery. This review aims to develop a broader understanding of PC, discussing its specific indications, patient management, technical factors, imaging guidance, and outcomes following the procedure.

Acute cholecystitis in high risk surgical patients: percutaneous cholecystostomy versus laparoscopic cholecystectomy (CHOCOLATE trial): study protocol for a randomized controlled trial

BACKGROUND

Laparoscopic cholecystectomy in acute calculous cholecystitis in high risk patients can lead to significant morbidity and mortality. Percutaneous cholecystostomy may be an alternative treatment option but the current literature does not provide the surgical community with evidence based advice.

METHODS/DESIGN

The CHOCOLATE trial is a randomised controlled, parallel-group, superiority multicenter trial. High risk patients, defined as APACHE-II score 7-14, with acute calculous cholecystitis will be randomised to laparoscopic cholecystectomy or percutaneous cholecystostomy. During a two year period 284 patients will be enrolled from 30 high volume teaching hospitals. The primary endpoint is a composite endpoint of major complications within three months following randomization and need for re-intervention and mortality during the follow-up period of one year. Secondary endpoints include all other complications, duration of hospital admission, difficulty of procedures and total costs.

DISCUSSION

The CHOCOLATE trial is designed to provide the surgical community with an evidence based guideline in the treatment of acute calculous cholecystitis in high risk patients.

Percutaneous cholecystostomy for acute cholecystitis: ten-year experience

PURPOSE

To review the clinical course of patients with acute cholecystitis treated by percutaneous cholecystostomy, and to identify risk factors retrospectively that predict outcome.

MATERIALS AND METHODS

A total of 106 patients diagnosed with acute cholecystitis were treated by percutaneous cholecystostomy during a 10-year period. Seventy-one (67%) presented to the emergency department (ED) specifically for acute cholecystitis, and 35 (23%) were inpatients previously admitted for other conditions. Outcomes of the two groups were compared with respect to severity of illness, leukocytosis, bile culture, liver function tests, imaging features, time intervals from onset of symptoms to medical and percutaneous intervention, and whether surgical cholecystectomy was later performed.

RESULTS

Overall, 72 patients (68%) showed an improvement clinically, whereas 34 (32%) showed no improvement or a clinically worsened condition after cholecystostomy. Patients who presented to the ED primarily with acute cholecystitis fared better (84% of patients showed improvement) than inpatients (34% showed improvement; P < .0001). Gallstones were identified in 54% of patients who presented to the ED, whereas acalculous cholecystitis was more commonly diagnosed in inpatients (54%). Patients with sepsis had worse outcomes overall (P < .0001). Bacterial bile cultures were analyzed in 95% of patients and showed positive results in 52%, with no overall effect on outcome. There was no correlation between the time of onset of symptoms until antibiotic therapy or cholecystostomy in either group. Long-term outcomes for both groups were better for those who later underwent cholecystectomy (P < .0001).

CONCLUSIONS

Outcomes after percutaneous cholecystostomy for acute cholecystitis are better when the disease is primary and not precipitated by concurrent illness.

Synchronous pyogenic liver abscess and acute cholecystitis: how to recognize it and what to do (emergency cholecystostomy followed by delayed laparoscopic cholecystectomy)

BACKGROUND

The treatment of synchronous pyogenic liver abscess (PLA) and acute cholecystitis (AC) may be challenging. Moreover, because of the similarity of symptoms and the suboptimal accuracy of ultrasound (US), PLA(s) may be undetected, unless a computer tomography (CT) scan is performed. The aims of this study were (1) to evaluate the results of emergency cholecystostomy (CS) and late laparoscopic cholecystectomy (LC) in such a population and (2) to identify the criteria for selecting patients with AC and a high risk of having synchronous PLA(s) for referral for a CT scan.

METHODS

A retrospective analysis of the outcome of 12 patients with AC and PLA(s) treated by emergency CS followed by delayed LC from January 1996 through May 2010 at a tertiary-care university hospital was performed. Clinical, laboratory, and radiological data of patients with synchronous AC and PLA(s) are compared with those of 66 patients with "simple" AC.

RESULTS

The association of age >55 years, temperature >38°C, WBC count >12,000/ml, and ASAT >50 UI/l and/or ALAT >75 UI/l allows for the selection of patients at high risk of PLA to undergo a CT scan (sensitivity: 100%; specificity: 86%). All treated patients had a sudden improvement within 24 h following CS. PLA was treated in 10/12 patients (83%). Hospital stay lasted 21.5 ± 3.5 days. Ten patients underwent elective LC 12 ± 4 weeks after CS with no conversion and 30% perioperative morbidity. Operating time was 91 min. Hospital stay was 1.7 days [7 patients (70%) underwent surgery as an outpatient].

CONCLUSIONS

A simple algorithm is presented for the selection of patients with AC to undergo a CT scan to identify synchronous PLA. Emergency CS followed by delayed LC is a viable, first-line treatment option for synchronous PLA and AC.

Role of hepatic portocholecystostomy ('gallbladder Kasai') in treating infants with biliary atresia

The aim of this study is to compare liver function and cholangitis episodes during the first year postoperatively between patients who undergo hepatic portocholecystostomy (HPC) and patients who undergo hepatic portoenterostomy (HPE). Records of six patients who underwent HPC for biliary atresia (BA) and 27 patients who underwent HPE for BA were reviewed retrospectively. Comparison was done of the patient's total bilirubin, albumin, and international normalized ratio values preoperatively and at 3 months, 6 months, and 1 year postoperatively. Comparison was also done of the occurrence of ascending cholangitis during the first year postoperatively and in rates of transplant and mortality during long-term follow-up. Preoperative laboratory values between the two groups were not significantly different. At 6 months, the patients who underwent HPC had significantly lower total bilirubin levels compared with those who underwent HPE (HPC 0.8 +/- 0.96, n = 4; HPE 4.93 +/- 7.73, n = 21; P < 0.05). No other laboratory values or rates of ascending cholangitis, transplant, or mortality showed a significant difference. Those patients who underwent HPC had significantly lower total bilirubin levels at 6 months postoperatively. This may suggest that HPC may be a superior operative technique for patients who are candidates for the operation.

Stapled cholecystojejunostomy for palliative treatment of the malignant jaundice; an effective and feasible alternative to hand-sewn method

Unresectable periampullary cancer is commonly characterized by painless jaundice and has a rapid evolution with dismal prognosis. Biliary drainage can be achieved by various techniques and approaches, with the endoscopic drainage being the preferred method. However, when open surgery is performed with the intent to resect a tumor which is finally found to be unresectable, open drainage of the biliary tree is indicated. We present a new technique of cholecystojejunostomy using a circular mechanical stapler, which could be used in patients with intact gallbladder and widely patent the cystic duct. The described cholecystoenterostomy with the use of a circular mechanical stapler is the first reported in the literature. The procedure has been successfully used in 6 patients with excellent results. No early recurrence of biliary obstruction, cholangitis or post-operative anastomotic complications were observed. The relative simplicity of the procedure, the shorter operative time and the effective relief of jaundice, are the main advantages of the proposed technique. We believe that this method needs further investigation and can be proved effective in reducing hospitalization and anastomotic complications, compared to hand-sewn techniques.

Better treatment strategies for patients with acute cholecystitis and American Society of Anesthesiologists classification 3 or greater

PURPOSE

Laparoscopic cholecystectomy is the best treatment choice for acute cholecystitis. However, it still carries high conversion and mortality rates. The purpose of this study was to find out better treatment strategies for high surgical risk patients with acute cholecystitis.

MATERIALS AND METHODS

Between January 2002 and June 2008, we performed percutaneous cholecystostomy instead of emergency cholecystectomy in 44 patients with acute cholecystitis and American Society of Anesthesiologists (ASA) classification 3 or greater. This was performed in 31 patients as a bridge procedure before elective cholecystectomy (bridge group) and as a palliative procedure in 11 patients (palliation group).

RESULTS

The mean age of patients was 71.6 years (range 52-86 years). The mean ASA classifications before and after percutaneous cholecystostomy were 3.3 +/- 0.5 and 2.5 +/- 0.6, respectively, in the bridge group, and 3.6 +/- 0.7 and 3.1 +/- 1.0, in the palliation group, respectively. Percutaneous cholecystostomy was technically successful in all patients. There were two deaths after percutaneous cholecystostomy in the palliation group due to underlying ischemic heart disease and multiple organ failure. Resumption of oral intake was possible 2.9 +/- 1.8 days in the bridge group and 3.9 +/- 3.5 days in the palliation group after percutaneous cholecystostomy. We attempted 17 laparoscopic cholecystectomies and experienced one failure due to bile duct injury (success rate: 94.1%). The postoperative course of all cholecystectomy patients was uneventful.

CONCLUSION

Percutaneous cholecystostomy is an effective bridge procedure before cholecystectomy in patients with acute cholecystitis and ASA classification 3 or greater.

Comparison of early outcome from transperitoneal versus transhepatic percutaneous cholecystostomy

BACKGROUND/AIMS

To determine whether there is a statistically significant difference in the short-term clinical outcome in patients undergoing percutaneous cholecystostomy based on the anatomic route of gallbladder puncture that is, transhepatic versus transperitoneal.

METHODOLOGY

Our population consisted of 132 patients who: 1) presented with acute cholecystitis, 2) were at high risk for surgery because of comorbid conditions, 3) underwent percutaneous cholecystostomy either using computed tomography guidance or ultrasound guidance and whose anatomic route was known: the transhepatic percutaneous cholecystostomy group comprised 59 patients, the transperitoneal group 73 patients. Demographic characteristics and clinical parameters of the groups were compared statistically, as were postprocedure hospital course, complications and time to hospital discharge.

RESULTS

The two groups were similar in demographic characteristics. There was a statistically significant tendency for computed tomography-guided percutaneous cholecystostomy to be transhepatic, and for ultrasound-guided percutaneous cholecystostomy to be transperitoneal. There were no differences in short-term postprocedure complications between the two groups. There was a tendency for shorter time to hospital discharge following transperitoneal percutaneous cholecystostomy.

CONCLUSIONS

Transperitoneal and transhepatic percutaneous cholecystostomy are similar in short-term safety, with no significant difference in complication rate. The interventional radiologist can feel secure in performing percutaneous cholecystostomy using either approach.

[Percutaneous cholecystostomy and papilloplasty in elderly high-risk patient. Case report]

When acute cholecystitis is suspected in a very high-risk patient, percutaneous cholecystostomy should be considered as a safe and effective temporary management of patients with gallstones. Whenever possible, percutaneous cholecystostomy should be followed by laparoscopic cholecystectomy. In elderly patients who are inappropriate surgical candidates because of severe concomitant systemic diseases, less invasive treatments may prevent recurrence. Our experience shows the feasibility of percutaneous cholecystostomy to achieve an effective treatment of acute cholecystitis in surgical high-risk patients with a physiologic biliary drainage of gallstones in duodenum to prevent recurrence. Moreover we demonstrated the feasibility of a concomitant percutaneous treatment of biliary disease.

Cholecystectomy or not after percutaneous cholecystostomy for acute calculous cholecystitis in high-risk patients

BACKGROUND/AIMS

This study aims to evaluate the outcomes of percutaneous cholecystostomy for acute calculous cholecystitis in patients with high surgical risk and determine whether subsequent cholecystectomy is beneficial and necessary. Percutaneous cholecystostomy has been shown to be a safe treatment option for patients suffering from acute cholecystitis but at high risk for emergency surgery. Controversies still exist on the approach of the cholecystostomy and the subsequent management of these patients.

METHODOLOGY

From January 1996 to March 2004, percutaneous cholecystostomy was performed on 65 patients that suffered from acute calculous cholecystostomy but were considered high risk for emergency surgery (American Society of Anesthesiologists grade III or IV). Their clinical outcomes were described and risk factors for in-hospital mortality and recurrence of cholecystitis were identified by univariate and multivariate analysis.

RESULTS

Percutaneous cholecystostomy was successfully performed in all patients (100%). The clinical response rate was 91%. The in-hospital mortality was 12.3%. Shock on admission was found to be a single independent risk factor for in-hospital death (p=0.006; odd ratio = 16.5; 95% CI = 2.2-123.1). Twenty-four patients underwent subsequent cholecystectomy whereas 33 did not. The 1-year and 3-year recurrence of acute cholecystitis were 35% and 46% respectively in patients who did not have subsequent cholecystectomy. Stone size > or = 1cm was independently associated with higher recurrence of acute cholecystitis (p=0.01; hazard ratio = 6.3, 95% CI 1.6-25.5). However, there was no difference in 1-year and 3-year overall survival between patients with or without cholecystectomy (82% Vs 81% and 59% Vs 63%, p=0.79).

CONCLUSIONS

Percutaneous cholecystostomy is a safe and promising treatment for acute calculous cholecystitis in patients who are at high risk for emergency surgery. Cholecystectomy after the resolution of cholecystitis and optimization of associated medical illnesses is always advisable in order to prevent recurrent cholecystitis. However, the limited survival of these patients because of their old age and medical co-morbidities should be taken into consideration.

EUS-guided transmural cholecystostomy as rescue management for acute cholecystitis in elderly or high-risk patients: a prospective feasibility study

BACKGROUND

Although EUS-guided drainage procedures have been used to collect peripancreatic fluids, little is known regarding EUS-guided transmural gallbladder drainage for high-risk patients with acute cholecystitis.

OBJECTIVE

Our purpose was to evaluate the technical feasibility and outcomes of EUS-guided transmural cholecystostomy as rescue management in elderly and high-risk patients with acute cholecystitis.

DESIGN

Single-center prospective study.

SETTING

Tertiary referral center.

PATIENTS

Nine elderly or high-risk patients diagnosed with acute cholecystitis.

INTERVENTIONS

All inflamed gallbladders were drained by EUS-guided transmural cholecystostomy.

MAIN OUTCOME MEASUREMENT

Clinical resolution of acute cholecystitis.

RESULTS

After the drainage procedures, there were no immediate complications such as bleeding, bile leak, or peritonitis, except for 1 patient who had pneumoperitoneum. After EUS-guided transmural cholecystostomy, all patients showed rapid clinical improvement within 72 hours.

LIMITATIONS

Small number of patients.

CONCLUSION

EUS-guided transmural cholecystostomy may be feasible and safe as initial, interim, or even definitive treatment of patients with severe acute cholecystitis who are at high operative risk for immediate cholecystectomy.

Minimally Invasive Cholecystostomy in the Dog: Evaluation of Placement Techniques and Use in Extrahepatic Biliary Obstruction

OBJECTIVE

To evaluate 4 methods of cholecystostomy catheter placement and to report on laparoscopic (Lap) cholecystostomy for the management of extrahepatic biliary obstruction (EHBO) in 3 dogs.

STUDY DESIGN

Experimental study and clinical report.

ANIMALS

Cadaveric dogs (n=20); 2 canine and 1 feline patient.

METHODS

Pigtail cholecystostomy catheters were inserted in 20 canine cadavers using ultrasound (US) or Lap guidance. Insertion routes were either transperitoneal or transhepatic. Methods studied included Lap-transperitoneal, US-transperitoneal, US-transhepatic, and US-Seldinger (n=5 dogs/group). Insertion success, pleural penetration, and insertion site leakage (Lap-transperitoneal group) were evaluated. Three clinical EHBO cases were treated by Lap-transperitoneal technique.

RESULTS

Insertion success was 100% by Lap-transperitoneal but 0% with US-transperitoneal and US-Seldinger methods. US-transhepatic yielded 3 of 5 successful placements. The pleura was penetrated in all US-transhepatic and US-Seldinger insertions. Leakage pressure for Lap-transperitoneal catheters averaged 75 cm H2O (+/-20 cm H2O). Lap-transperitoneal cholecystostomy resulted in marked improvement in 2 dogs, but the catheter became obstructed in the cat. One dog spontaneously regained common bile duct patency and the remaining 2 animals had successful cholecystoenterostomy.

CONCLUSIONS

In cadaver testing, the Lap-transperitoneal cholecystostomy method was superior based on high insertion success with no pleural penetration. In 2 clinical cases, Lap-transperitoneal placement successfully provided biliary drainage for patient stabilization.

CLINICAL RELEVANCE

The role for temporary cholecystostomy has yet to be established, but may aid patient stabilization and mortality reduction in EHBO.

[Cholecystostomy in emergent surgery of hepatopancreatobiliary zone organs]

Results of cholecystostomy formation in 26 elderly or senile patients for urgent diseases of hepatopancreatobiliary zone organs and severe coexistent pathology of respiratory organs, cardiovascular system and intoxication, were analyzed. The tactics was proposed and indications for cholecystectomy formation were substantiated.

Ultrasound guided percutaneous cholecystostomy in high-risk patients for surgical intervention

AIM

To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia.

METHODS

The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases.

RESULTS

Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 13 x 10(3)+/-1 x 10(3) microg/L, P < 0.05 for 24 h after PC; 13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 8.3 x 10(3)+/-1.2 x 10(3) microg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2+/-18.5 mg/L vs 27.3+/-10.4 mg/L, P < 0.05 for 24 h after PC; 51.2+/-18.5 mg/L vs 5.4+/-1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38+/-0.35 centigrade vs 37.3+/-0.32 centigrade, P < 0.05 for 24 h after PC; 38+/-0.35 centigrade vs 36.9+/-0.15 centigrade, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter.

CONCLUSION

As an alternative to surgery, percutaneous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy.

Obstructive cholelithiasis and cholecystitis in a keeshond

A 10-year-old, neutered male, keeshond was presented for vomiting, lethargy, icterus, and anorexia. Obstructive cholelithiasis was diagnosed based on analysis of a serum biochemical profile, abdominal radiographs, and ultrasonography. Choleliths were removed from the gall bladder and common bile duct via a cholecystotomy.

[Treatment of obstruction of extrahepatic biliary pathways by antireflux, bilio-cholecystic (cystico) enteroanastomosis methods]

The main target of our investigations was the development of antireflux, bilio-cholecysto (cystico) enteral anastomosis method for the surgical treatment of extrahepatic biliary duct obstruction. We were using the cholecystic duct spiral valve (Lutkens valve, Haister valve) as the antireflux structure. In this case the bile drains into the biliary cyst not through the cholecystic duct but through the extrahepatic biliary duct - the bilio-cholecystic anastomosis. Such an interposition of cholecystic and spiral valves promotes inhibition of chemical reflux between extrahepatic ducts and gastrointestinal tract, from digestive tract into the cholecystic and intrahepatic biliary tracts. Method developed and tested by us involves creation of blio-cholecystic (cystico) entero anastomosis, namely creation of biliary duct-cholecystic (cystico)-duodenoanastomosis. 3 successful experimental operations have been performed using the above presented approach. Sutures were taken of on the seventh day, animals were housed under investigations for 10-14 days, faecal masses had normal appearance.

Removal of a trapped endoscopic catheter from the gallbladder via percutaneous transhepatic cholecystostomy: technical innovation

BACKGROUND

Percutaneous cholecystostomy is used for a variety of clinical problems.

METHODS

Percutaneous cholecystostomy was utilized in a novel setting to resolve a problematic endoscopic situation.

OBSERVATIONS

Percutaneous cholecystostomy permitted successful removal of a broken and trapped endoscopic biliary catheter, in addition to helping treat cholecystitis.

CONCLUSION

Another valuable use of percutaneous cholecystostomy is demonstrated, as well as emphasizing the importance of the interplay between endoscopists and interventional radiologists.
