Effective use of percutaneous cholecystostomy in high-risk surgical patients: techniques, tube management, and results

Early Laparoscopic Cholecystectomy Versus Percutaneous Cholecystostomy Followed by Delayed Laparoscopic Cholecystectomy in Patients with Grade II Acute Cholecystitis According to Tokyo Guidelines TG18

Introduction: In the past, most patients with acute cholecystitis (AC) were treated conservatively. However, strong evidence from various studies has shown that laparoscopic cholecystectomy (LC) is safe and should be the primary treatment for AC. However, this may not be the case for all AC grades. This study aimed to compare two recommended approaches for grade II AC as outlined in the Tokyo guidelines TG18, focusing on early operative outcomes. Methods: We conducted a retrospective review of medical records for all patients diagnosed with grade II AC. The study compared patients who underwent early LC (group A, n = 130) with those who initially received percutaneous cholecystostomy (PC) followed by LC (group B, n = 90). Results: Both groups had similar Tokyo classification parameters. However, there were significant differences in baseline data, operative challenges, and postoperative complications. Cholecystostomy-related complications were observed in seven patients. The conversion rate for was 25% for group A and 5% for group B. The incidence of intraoperative biliary injury was 10% for group A and 2.2% for group B. In group A, 92% of patients with biliary injury and 80% of those who required conversion to open surgery had evidence of localized inflammation around the gallbladder. Conclusion: For selected patients with grade II AC and higher risks, PC placement can be beneficial in preventing life-threatening consequences. The study suggests a 2-month interval between PC and subsequent LC. Overall, performing LC after PC was found to be easier than early LC. Local inflammatory changes, including empyema, were associated with higher complication rates in the early LC group.

Percutaneous cholecystostomy as a bridge therapy in the geriatric age group with acute cholecystitis

OBJECTIVE

The aim of this study was to investigate the efficacy of percutaneous cholecystostomy (PC) in the geriatric patients with acute cholecystitis.

MATERIALS AND METHODS

The records of geriatric patients with high surgical risk who underwent percutaneous cholecystostomy for acute cholecystitis were reviewed retrospectively.

RESULTS

The median age of 134 patients who underwent percutaneous cholecystostomy was 77 (65-98) years and 63.4% were women. The mean length of hospital stay was 5 (4-18) days, and the follow-up period until the procedure was 2 (1-6) days. Murphy's sign was positive in 79.1% of patients on physical examination, and the remaining patients (20.9%) had only tenderness on examination. As USG findings, 59.0% of the patients had a gall bladder wall thickness (> 4 mm) with pericholecystic fluid. Additional imaging method, abdominal CT, was performed in 29 patients (21.6%), MRCP was performed in three patients (2.2%), and ERCP was performed in one patient (0.7%). Bacterial growth was detected in 27.6% of the bile cultures performed. During the follow-up period, laparoscopic cholecystectomy was performed in 60.4% of the patients and open cholecystectomy was performed in 5.2% of the patients electively. 34.3% of the patients did not undergo any surgery. Bile leakage was detected in two patients (1.5%) as a procedure-related complication, and no mortality was observed.

CONCLUSION

Abdominal ultrasonography-guided PC is a safe and effective method in the management of acute cholecystitis in high-risk patients in the geriatric age group.

Management of complex acute biliary disease for the general surgeon: A narrative review

Acute gallbladder diseases are a common surgical emergency faced by General Surgeons that can sometimes be quite challenging. These complex biliary diseases require multifaceted and expeditious care, optimized based on hospital facility and operating room (OR) resources and the expertise of the surgical team. Effective management of biliary emergencies requires two foundational principles: achieving source control while mitigating the risk of injury to the biliary tree and its blood supply. This review article highlights salient literature on seven complex biliary diseases: acute cholecystitis, cholangitis, Mirizzi syndrome, gallstone ileus with cholecystoenteric fistula, gallstone pancreatitis, gall bladder cancer, and post-cholecystectomy bile leak.

Increased difficulty and complications of delayed laparoscopic cholecystectomy following percutaneous transhepatic gallbladder drainage in acute cholecystitis: a retrospective study

BACKGROUND

Percutaneous transhepatic gallbladder drainage (PTGBD) is a relatively less invasive alternative treatment to cholecystostomy. However, the influence of the difficulty of delayed laparoscopic cholecystectomy (DLC) after PTGBD on clinical outcomes remains unknown. This study aimed to evaluate the clinical effects of DLC following PTGBD.

METHODS

The clinical data of 113 patients diagnosed with moderate (grade II) acute cholecystitis according to the 2018 Tokyo Guidelines in the acute phase and who underwent DLC in our hospital from January 2018 to February 2022 were retrospectively collected and separated into two groups according to whether they received PTGBD treatment in the acute stage. The PTGBD group comprised 27 cases, and the no-PTGBD group included 86 cases. The TG18 difficulty score was used to evaluate every surgical procedure in the cases by reviewing the surgical videos. The clinical baseline characteristics and post-treatment outcomes were also evaluated.

RESULTS

Both groups showed significant differences in length of postoperative stay, blood loss, operation time, and difficulty score. The PTGBD group showed a significantly longer postoperative stay and operation time, more blood loss, and a much higher difficulty score than the no-PTGBD group. Conversion rates did not differ. The morbidity rate in the PTGBD group was statistically higher.

CONCLUSIONS

PTGBD is an efficient way to relieve the symptoms of acute cholecystitis. However, it may increase the difficulty and complications of DLC.

A clinician's guide to gallstones and common bile duct (CBD): A study protocol for a systematic review and evidence-based recommendations

Background and Aims

Gallstones are one of the most common and costly diseases of the gastrointestinal tract and occur when a combination of deposits consisting of fat or minerals accumulate in the gallbladder or common bile duct (CBD). This paper provides a comprehensive review of gallstone epidemiology, diagnosis, and management, focusing on current clinical guidelines and evidence-based approaches.

Methods

A systematic literature review gathered information from various sources, including PubMed, Trip, Google Scholar, Clinical Key, and reputable medical association websites. Keywords related to gallstones, CBD stones, cholelithiasis, choledocholithiasis, and guidelines were used to extract relevant recommendations. Expert consultations and consensus meetings localized the recommendations based on the target population and available resources.

Results

The paper discusses demographic factors, dietary habits, and lifestyle influences contributing to gallstone formation. Gallstones are categorized into cholesterol and pigment types, with varying prevalences across regions. Many individuals with gallstones remain asymptomatic, but complications can lead to serious and potentially life-threatening conditions. Diagnosis relies on history, physical examination, laboratory tests, and transabdominal ultrasound. Specific predictive factors help categorize patients into high, moderate, or low probability groups for CBD stones.

Conclusion

Evidence-based recommendations for gallstone diagnosis and management are presented, emphasizing individualized treatment plans. Surgical interventions, nonsurgical treatments like oral litholysis with UDCA, and stenting are discussed. The management of gallstones in pregnant women is also addressed, considering the potential risks and appropriate treatment options during pregnancy.

Evidence-based clinical practice guidelines for cholelithiasis 2021

The Japanese Society of Gastroenterology first published evidence-based clinical practice guidelines for cholelithiasis in 2010, followed by a revision in 2016. Currently, the revised third edition was published to reflect recent evidence on the diagnosis, treatment, and prognosis of cholelithiasis conforming to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Following this revision, the present English version of the guidelines was updated and published herein. The clinical questions (CQ) in the previous version were reviewed and rearranged into three newly divided categories: background questions (BQ) dealing with basic background knowledge, CQ, and future research questions (FRQ), which refer to issues that require further accumulation of evidence. Finally, 52 questions (29 BQs, 19 CQs, and 4 FRQs) were adopted to cover the epidemiology, pathogenesis, diagnosis, treatment, complications, and prognosis. Based on a literature search using MEDLINE, Cochrane Library, and Igaku Chuo Zasshi databases for the period between 1983 and August 2019, along with a manual search of new information reported over the past 5 years, the level of evidence was evaluated for each CQ. The strengths of recommendations were determined using the Delphi method by the committee members considering the body of evidence, including benefits and harms, patient preference, and cost-benefit balance. A comprehensive flowchart was prepared for the diagnosis and treatment of gallbladder stones, common bile duct stones, and intrahepatic stones, respectively. The current revised guidelines are expected to be of great assistance to gastroenterologists and general physicians in making decisions on contemporary clinical management for cholelithiasis patients.

Acute cholecystitis: Which flow-chart for the most appropriate management?

Acute cholecystitis (AC) is a very common disease in clinical practice. Laparoscopic cholecystectomy remains the gold standard treatment for AC, however due to aging population, the increased prevalence of multiple comorbidities and the extensive use of anticoagulants, surgical procedures may be too risky when dealing with patients in emergency settings. In these subsets of patients, a mini-invasive management may be an effective option, both as a definitive treatment or as bridge-to-surgery. In this paper, several non-operative treatments are described and their benefits and drawbacks are highlighted. Percutaneous gallbladder drainage (PT-GBD) is one of the most common and widespread techniques. It is easy to perform and has a good cost/benefit ratio. Endoscopic transpapillary gallbladder drainage (ETGBD) is a challenging procedure that is usually performed in high volume centers by expert endoscopists, and it has a specific indication for selected cases. EUS-guided drainage (EUS-GBD) is still not widely available, but it is an effective procedure that could have several advantages, especially in rate of reinterventions. All these treatment options should be considered together in a stepwise approach and addressed to patients after an accurate case-by-case evaluation in a multidisciplinary discussion. In this review, we provide a possible flowchart in order to optimize treatments, resource and provide to patients a tailored approach.

Endoscopic Ultrasound-Guided Gallbladder Drainage: Beyond Cholecystitis

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is an alternative to surgery for acute cholecystitis (AC) in poor operative candidates. However, the role of EUS-GBD in non-cholecystitis (NC) indications has not been well studied. We compared the clinical outcomes of EUS-GBD for AC and NC indications. Consecutive patients undergoing EUS-GBD for all indications at a single center were retrospectively analyzed. Fifty-one patients underwent EUS-GBD during the study period. Thirty-nine (76%) patients had AC while 12 (24%) had NC indications. NC indications included malignant biliary obstruction (n = 8), symptomatic cholelithiasis (n = 1), gallstone pancreatitis (n = 1), choledocholithiasis (n = 1), and Mirizzi's syndrome (n = 1). Technical success was noted in 92% (36/39) for AC and 92% (11/12) for NC (p > 0.99). The clinical success rate was 94% and 100%, respectively (p > 0.99). There were four adverse events in the AC group and 3 in the NC group (p = 0.33). Procedure duration (median 43 vs. 45 min, p = 0.37), post-procedure length of stay (median 3 vs. 3 days, p = 0.97), and total gallbladder-related procedures (median 2 vs. 2, p = 0.59) were similar. EUS-GBD for NC indications is similarly safe and effective as EUS-GBD in AC.

Early cholecystectomy following percutaneous transhepatic gallbladder drainage is effective for moderate to severe acute cholecystitis in the octogenarians

BACKGROUND

Acute cholecystitis (AC) is a life-threatening infectious/inflammatory disease in older patients. This study aimed to investigate the safety and optimal timing of surgery in patients aged ≥ 80 years with moderate to severe AC who received percutaneous transhepatic gallbladder drainage (PTGBD).

METHODS

From January 2008 to February 2021, 152 patients were retrospectively enrolled. Clinical outcomes were compared among patients who received laparoscopic cholecystectomy (LC), open cholecystectomy (OC), and conversion surgery, and between those who received early (< 6 weeks after PTGBD) and delayed cholecystectomy (≥ 6 weeks after PTGBD). Logistic regression analysis was used to identify risk factors for recurrent AC, further biliary events, conversion, and perioperative complications.

RESULTS

Sixty-seven patients underwent LC, 62 underwent OC, and 23 underwent conversion surgery. Operation-related complications and mortality rates did not differ among the types of surgery; however, LC group had shorter operative time than the other groups. Eighty-two patients underwent early cholecystectomy, while 70 underwent delayed cholecystectomy. There were no differences in operative time, operation-related complications, and mortality rates between the groups. However, higher rates of recurrent AC and biliary events were observed in the delayed cholecystectomy group (52.9% vs. 4.9% and 57.1% vs. 8.5%, p < 0.001). On multivariate analysis, delayed cholecystectomy was a significant risk factor for recurrent AC (odds ratio [OR] = 19.42, p < 0.001) and further biliary events (OR = 15.95, p < 0.001).

CONCLUSIONS

Early cholecystectomy is recommended for patients aged ≥ 80 years with moderate to severe AC following PTGBD.

Outcomes of endoscopic retrograde cholangiopancreatography-guided gallbladder drainage compared to percutaneous cholecystostomy in acute cholecystitis

Backgrounds/Aims

Endoscopic retrograde cholangiopancreatography-guided gallbladder drainage (ERGD) is an alternative to percutaneous cholecystostomy (PTC) for hospitalized acute cholecystitis (AC) patients.

Methods

We retrospectively analyzed propensity score matched (PSM) AC hospitalizations using the National Inpatient Sample database between 2016 and 2019 to compare the outcomes of ERGD and PTC.

Results

After PSM, there were 3,360 AC hospitalizations, with 48.8% undergoing PTC and 51.2% undergoing ERGD. There was no difference in median length of stay between the PTC and ERGD cohorts (p = 0.110). There was a higher median hospitalization cost in the ERGD cohort, $62,562 (interquartile range [IQR] $40,707-97,978) compared to PTC, $40,413 (IQR $25,244-65,608; p < 0.001). The 30-day inpatient mortality was significantly lower in hospitalizations with ERGD compared to PTC (adjusted hazard ratio 0.16, 95% confidence interval [CI]: 0.1-0.41; p < 0.001). There was no difference in association with blood transfusions, acute renal failure, ileus, small bowel obstruction, and open cholecystectomy conversion (p > 0.05) between hospitalizations with ERGD and PTC. There was lower association of acute hypoxic respiratory failure (adjusted ratio [AOR] 0.46, 95% CI: 0.29-0.72; p = 0.001), hypovolemia (AOR 0.66, 95% CI: 0.49-0.82; p = 0.009) and higher association of lower gastrointestinal bleed (AOR 1.94, 95% CI: 1.48-2.54; p < 0.001) with ERGD compared to PTC.

Conclusions

ERGD is a safer alternative to PTC in patients with AC. The risk complications are lower in ERGD compared to PTC but no difference exists based on mortality or conversion to open cholecystectomy.

Novel anchoring device for endoscopic ultrasound-guided gallbladder drainage: secondary publication

BACKGROUND

Recently, endoscopic ultrasound-guided gallbladder drainage has attracted much attention. However, the risk management of adverse events and techniques to avoid them are not yet mature. Difficulty dilating the fistula with a dilator or placing a stent for drainage often prolongs the procedure time, which increases the risk of peritonitis or the procedure failure rate. Therefore, the result of the procedure will be unstable, and one cause is the lack of adhesion between the gallbladder and the digestive tract walls.

METHODS

We developed an anchor to fix the stomach and gallbladder walls prior to endoscopic ultrasound-guided gallbladder drainage in four live pigs using the anchor.

RESULTS

The stomach and gallbladder walls were fixed in three pigs, and technical success was achieved in all three pigs. In two pigs that were dissected 17 and 34 days post-procedure, respectively, fixation occurred in one pig. In the other pig, anchoring of the gallbladder and stomach walls did not occur because the wings of the anchor in the gallbladder were damaged.

CONCLUSIONS

Although issues remain regarding efficacy and safety, we plan to make improvements in this novel device and aim for clinical application.

Percutaneous Cholecystostomy Tube for Acute Cholecystitis: Quantifying Outcomes and Prognosis

BACKGROUND

Percutaneous cholecystostomy tubes (PCT) are utilized in the management of acute cholecystitis in patients deemed unsuitable for surgery. However, the drive for these decisions and the outcomes remain understudied. We sought to characterize the practices and utilization of PCT and evaluate associated outcomes at an urban medical center.

METHODS

Patients undergoing PCT placement over a 12-y study period ending May 2019 were reviewed. Demographics, clinical presentation, labs, imaging studies, and outcomes were abstracted. The primary and secondary outcomes were 30-d mortality and interval cholecystectomy, respectively.

RESULTS

Two hundred and four patients met inclusion criteria: 59.3% were male with a median age of 67.5 y and a National Surgical Quality Improvement Program (NSQIP) risk of serious complication of 8.0%. Overall, 57.8% of patients were located in an intensive care unit setting. The majority (80.9%) had an ultrasound and 48.5% had a hepatobiliary iminodiacetic acid scan. The overall 30-d mortality was 31.9%: 41.5% for intensive care unit and 18.6% for ward patients (P < 0.01). Of patients surviving beyond 30 d (n = 139), the PCT was removed from 106 (76.3%), and a cholecystectomy was performed in 55 (39.6%) at a median interval of 58.0 d. A forward logistic regression identified total bilirubin (Adjusted Odds Ratio: 1.12, adjusted P < 0.01) and NSQIP risk of serious complication (Adjusted Odds Ratio: 1.16, adjusted P < 0.01) as the only predictors for 30-d mortality.

CONCLUSIONS

Patients selected for PCT placement have a high mortality risk. Despite subsequent removal of the PCT, the majority of surviving patients did not undergo an interval cholecystectomy. Total bilirubin and NSQIP risk of serious complication are useful adjuncts in predicting 30-d mortality in these patients.

Comparison of laparoscopic cholecystectomy and delayed laparoscopic cholecystectomy in aged acute calculous cholecystitis: a cohort study

BACKGROUND

In elderly patients with calculous acute cholecystitis, the risk of emergency surgery is high, and percutaneous cholecystostomy tube drainage (PC) combined with delayed laparoscopic cholecystectomy (DLC) may be a good choice. We retrospectively compared laparoscopic cholecystectomy (LC) to DLC after PC to determine which is the better treatment strategy.

METHOD

We performed a retrospective cohort analysis of 752 patients with acute calculous cholecystitis. Patients with the following conditions were included: (1) age > 65 years old; (2) patients with a grade 2 or 3 severity of cholecystitis according to the 2013 Tokyo Guidelines (TG13); (3) the surgeons who performed the LC were professors or associate professors and (4) the DLC was performed in our hospital after PC. Patients who missed their 30-day follow-up; were diagnosed with bile duct stones, cholangitis or gallstone pancreatitis or were pregnant were excluded from the study. A total of 51 of 314 patients who underwent LC and 73 of 438 patients who underwent PC + DLC were assessed. PC + DLC and LC patients were matched by cholecystitis severity grade according to the TG13, and the National Surgical Quality Improvement Program (NSQIP) calculator was used to predict mortality (n = 21/group). Preoperative characteristics and postoperative outcomes were analysed.

RESULTS

Compared to the matched LC group, the DLC group had less intraoperative bleeding (42.2 vs 75.3 mL, p = 0.014), shorter hospital stays (4.9 vs 7.4 days, p = 0.010) and lower rates of type A bile duct injury (4.8% vs 14.3%, p = 0.035) and type D (0 vs 9.5%, p = 0.002) according to Strasberg classification, residual stones (4.8 vs 14.3%, p = 0.035) and gastrointestinal organ injury (0 vs 3.6%, p < 0.001). Patients in the DLC group had lower incidences of ICU admission and death and a significantly lower incidence of repeat surgery.

CONCLUSION

In elderly patients treated for acute calculous cholecystitis, the 30-day mortality and complication rates were lower for PC + DLC than for LC. However, the total hospitalisation time was significantly prolonged and the costs were significantly higher for PC + DLC.

A case of nontyphoidal Salmonella gastroenteritis complicated with acute acalculous cholecystitis

Background: Acute acalculous cholecystitis is an acute inflammation of the gall bladder in the absence of gallstones and is known to occur in those critically ill patients, including those after major surgery, patients with trauma or burn, and patients with sepsis and various infectious diseases. Salmonella infection is one of the commonest food-borne illnesses. Although cholecystitis is a well-reported complication of typhoidal Salmonella infection, it is rarely reported in nontyphoidal Salmonella infection. Case Presentation: We report a case of nontyphoidal Salmonella infection complicated by acute acalculous cholecystitis. Prompt diagnosis was made and the patient was recovered after percutaneous cholecystostomy. Conclusion: Acute acalculous cholecystitis is a rare, but potentially lethal, complication of Salmonella infection. The clinical presentation is often subtle; therefore, a high degree of suspicion should be maintained in managing patients with Salmonella infection and ongoing sepsis.

Outcomes and limitations in EUS-guided gallbladder drainage

EUS-guided gallbladder drainage (EUS-GBD) is gaining popularity as an option for drainage of the gallbladder in patients suffering from acute cholecystitis but at high risk for cholecystectomy. It allows internal drainage of the gallbladder and avoidance of the external tube as used in percutaneous cholecystostomy (PT-GBD). It may also provide additional benefits, including reduced re-admissions and re-interventions. In this chapter, we review the indications and outcomes of EUS-GBD. Furthermore, the follow-up management of patients that received EUS-GBD would be outlined.

[Percutaneous biliary and gallbladder interventions]

CLINICAL ISSUE

Percutaneous transhepatic biliary and gall bladder interventions play an important role in the diagnosis and therapy of biliary tract diseases.

PERFORMANCE

With technical success rates up to 99% as well as complications rates up to a maximum of 26% they showed good results. Indications were opacification of the biliary tree as well as treatment of biliary system pathologies, such as drainage and stents.

ACHIEVEMENTS

Interventions were used if endoscopic approaches are not possible or exploited. We describe the current state of knowledge and the range for percutaneous biliary/gall bladder interventions and give an overview of technical approaches for fundamental interventional procedures, including percutaneous transhepatic biliary drainage.

PRACTICAL RECOMMENDATIONS

Percutaneous transhepatic biliary and gall bladder interventions are safe and effective treatments for benign and malignant stenosis, postoperative complications and risk patients with cholecystitis.

Abdominal Wall Abscess Secondary to Cholecystocutaneous Fistula via Percutaneous Cholecystostomy Tract

Cholecystocutaneous fistulas (CCFs) are an increasingly rare consequence of chronic gallbladder inflammation and disease. Historically, they were commonly noted in the literature by Courvoisier, Naunyn, and Bonnet in the late 1800s. Due to improvements in diagnostic imaging and treatment options in the last century, there has been a marked decrease in the incidence of the CCF cases in the literature. From the late 1890s to 1949, there were only 37 cases presented in the literature; only 28 cases have been reported since 2007. This case is only the second noted CCF in the literature that followed percutaneous cholecystostomy drain placement and removal.

General surgery was consulted on a 60-year-old morbidly obese female, who presented to the emergency department after one week of fever, right upper quadrant (RUQ) pain, nausea, emesis, and shortness of breath. She had a history of acute cholecystitis treated with a cholecystostomy tube the year prior, but after the removal of the tube, she was lost to follow up. She was found to have a 14cm x 5cm fluctuant abdominal wall abscess in her RUQ that was treated with incision and drainage (I&D) along with ertapenem. She continued to improve until day 7 post-I&D when yellowish-green discharge was noted draining from the wound. After a negative hepatobiliary iminodiacetic acid scan, a follow-up abdominal computed tomography (CT) showed a contracted gallbladder with fistula formation underlying the abscess location, near the site of her prior cholecystostomy tube. A robotic-assisted cholecystectomy was performed, which improved the wound drainage, and the patient was discharged home 5 days later.

This case is the only noted CCF presenting as a RUQ abscess after cholecystostomy drain placement. The patient lacks follow up after the removal of her percutaneous drain and continued inflammation in the gallbladder provided perfect nidus for the fistula formation. As seen in other CCF patients, cholecystectomy is the treatment of choice, and this case was successfully treated via robotic-assisted cholecystectomy with adhesiolysis.

Successful Cholecystectomy After Endoscopic Ultrasound Gallbladder Drainage Compared With Percutaneous Cholecystostomy, Can it Be Done?

BACKGROUND

Endoscopic ultrasound-guided gallbladder drainage (EGBD) with a lumen apposing metal stent is becoming a widely accepted alternative to percutaneous gallbladder drainage (PTGD) for patients who are not candidates for cholecystectomy (CCY). In some patients, medical comorbidites can improve, allowing them to undergo CCY. We compare feasibility and outcomes of interval CCY after EGBD versus PTGD.

METHODS

We conducted a multicentered international cohort study of patients who underwent EGBD or PTGD and then underwent interval CCY. Baseline patient demographics, procedural details, and follow-up data were recorded and compared.

RESULTS

In total, 34 patients were included. Thirteen patients underwent EGBD followed by CCY (mean age, 53.77±17.27, 46.15% male), and 21 patients underwent PTGD followed by CCY (mean age, 62.14±13.06, 61.9% male). There was no statistically significant difference in mean Charlson Comorbidity Index (P=0.12) or etiology of cholecystitis (P=0.85) between the 2 groups. All patients had a technically successful CCY. There was no difference between rates of open versus laparoscopic CCY (P=1). In addition, there was no difference in postsurgical adverse events (P=0.23).

CONCLUSIONS

Surgical CCY after EGBD with lumen apposing metal stent is safe and feasible for the management of cholecystitis. If patient's underlying medical conditions improve, previous EUS-GLB drainage should not preclude patients from undergoing CCY as part of standard of care.

Role of percutaneous cholecystostomy for acute acalculous cholecystitis: clinical outcomes of 271 patients

OBJECTIVES

To examine the outcomes of percutaneous cholecystostomy (PC) in patients with acute acalculous cholecystitis (AAC).

METHODS

The study population comprised 271 patients (mean age, 72 years; range, 22-97 years, male, n=169) with AAC treated with PC with or without subsequent cholecystectomy. Clinical data from total 271 patients were analysed, and outcomes were assessed according to whether the catheter was removed or remained indwelling. Patient survival and recurrence rates were calculated.

RESULTS

Symptom resolution and significant improvement of laboratory test values were achieved in 235 patients (86.7%) within 4 days after PC. Complications occurred in six patients (2.2%). Interval elective cholecystectomy was performed in 127 (46.8%) patients. Among the remaining 121 patients, successful removal of the PC catheter was achieved in 88 patients (72.7%) at a mean of 30 days (range, 4-365 days). Of the catheter removal group, 86/88 (97.7%) were successfully treated with the initial PC, whereas two (2.3%) experienced recurrence of cholecystitis. Cumulative recurrence rates were 1.1%, 2.7%, and 2.7% at 1, 2, and 8 years, respectively.

CONCLUSIONS

The good therapeutic outcomes of PC and low recurrence rate suggest that PC can be a definitive treatment option in the majority of AAC patients.

KEY POINTS

• Many patients with AAC are too ill to undergo cholecystectomy. • PC in AAC patients shows low complication and recurrence rate. • PC solely can be a definitive treatment option in the majority of AAC patients.

The management of intra-abdominal infections from a global perspective: 2017 WSES guidelines for management of intra-abdominal infections

Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in the emergency departments worldwide. The cornerstones of effective treatment of IAIs are early recognition, adequate source control, and appropriate antimicrobial therapy. Prompt resuscitation of patients with ongoing sepsis is of utmost important. In hospitals worldwide, non-acceptance of, or lack of access to, accessible evidence-based practices and guidelines result in overall poorer outcome of patients suffering IAIs. The aim of this paper is to promote global standards of care in IAIs and update the 2013 WSES guidelines for management of intra-abdominal infections.

Optimal timing of cholecystectomy after percutaneous gallbladder drainage for severe cholecystitis

Background

The Tokyo guideline for acute cholecystitis recommended percutaneous transhepatic gallbladder drainage followed by cholecystectomy for severe acute cholecystitis, but the optimal timing for the subsequent cholecystectomy remains controversial.

Methods

Sixty-seven patients who underwent either laparoscopic or open cholecystectomy after percutaneous transhepatic gallbladder drainage for severe acute cholecystitis were enrolled and divided into difficult cholecystectomy (group A) and non-difficult cholecystectomy (group B). Patients who had one of these conditions were placed in group A: 1) conversion from laparoscopic to open cholecystectomy; 2) subtotal cholecystectomy and/or mucoclasis; 3) necrotizing cholecystitis or pericholecystic abscess formation; 4) tight adhesions around the gallbladder neck; and 5) unsuccessfully treated using PTGBD. Preoperative characteristics and postoperative outcomes were analyzed.

Results

The interval between percutaneous transhepatic gallbladder drainage and cholecystectomy in Group B was longer than that in Group A (631 h vs. 325 h; p = 0.031). Postoperative complications occurred more frequently when the interval was less than 216 h compared to when it was more than 216 h (35.7 vs. 7.6%; p = 0.006).

Conclusions

Cholecystectomy for severe acute cholecystitis was technically difficult when performed within 216 h after percutaneous transhepatic gallbladder drainage.

Similar Efficacies of Endoscopic Ultrasound Gallbladder Drainage With a Lumen-Apposing Metal Stent Versus Percutaneous Transhepatic Gallbladder Drainage for Acute Cholecystitis

BACKGROUND & AIMS

Acute cholecystitis in patients who are not candidates for surgery is often managed with percutaneous transhepatic gallbladder drainage (PT-GBD). Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) with a lumen-apposing metal stent (LAMS) is an effective alternative to PT-GBD. We compared the technical success of EUS-GBD versus PT-GBD, and patient outcomes, numbers of adverse events (AEs), length of hospital stay, pain scores, and repeat interventions.

METHODS

We performed a retrospective study to compare EUS-GBD versus PT-GBD at 7 centers (5 in the United States, 1 in Europe, and 1 in Asia), from 2013 through 2015, in management of acute cholecystitis in patients who are not candidates for surgery. A total of 90 patients (56 men) with acute cholecystitis (61 calculous, 29 acalculous) underwent EUS-GBD (n = 45) or PT-GBD (n = 45). Data were collected on technical success, clinical success (resolution of symptoms or laboratory and/or radiologic abnormalities within 3 days of intervention), and need for repeat intervention. Characteristics were compared using Student t tests for continuous variables and the chi-square test, or the Fisher exact test, when appropriate, for categorical variables. Adverse events were graded according to American Society for Gastrointestinal Endoscopy definitions and compared using the Fisher exact test. Postprocedure pain scores were compared using the Mann-Whitney U test.

RESULTS

Baseline characteristics, type, and clinical severity of cholecystitis were comparable between groups. In the EUS-GBD group, noncautery LAMS were used in 30 patients and cautery-enhanced LAMS were used in 15. Technical success was achieved for 98% of patients in the EUS-GBD and 100% of the patients in the PT-GBD group (P = .88). Clinical success was achieved by 96% of patients in the EUS-GBD group and 91% in the PT-GBD group (P = .20). There was a nonsignificant trend toward fewer AEs in the EUS-GBD group (5 patients; 11%) than in the PT-GBD group (14 patients; 32%) (P = .065). There were no significant differences in the severity of the AEs: mild, 2 in the EUS-GBD group versus 5 in the PT-GBD group (P = .27); moderate, 4 versus 3 (P = .98); severe, 1 versus 3 (P = .62); or deaths, 1 versus 3 (P = .61). The mean postprocedure pain score was lower in the EUS-GBD group than in the PT-GBD group (2.5 vs 6.5; P < .05). The EUS-GBD group had a shorter average length of stay in the hospital (3 days) than the PT-GBD group (9 days) (P < .05) and fewer repeat interventions (11 vs 112) (P < .05). The average number of repeat interventions per patients was 0.2 ± 0.4 EUS-GBD group versus 2.5 ± 2.8 in the PT-GBD group (P < .05). Median follow-up after drainage was comparable in EUS-GBD group (215 days; range, 1-621 days) versus the PT-GBD group (265 days; range, 1-1638 days).

CONCLUSIONS

EUS-GBD has similar technical and clinical success compared with PT-GBD and should be considered an alternative for patients who are not candidates for surgery. Patients who undergo EUS-GBD seem to have shorter hospital stays, lower pain scores, and fewer repeated interventions, with a trend toward fewer AEs. A prospective, comparative study is needed to confirm these results.

Impact of scheduled laparoscopic cholecystectomy in patients with acute cholecystitis, following percutaneous transhepatic gallbladder drainage

Backgrounds/Aims

Frequently encountered in practice, the first-line treatment for acute cholecystitis is early or urgent cholecystectomy, with laparoscopic cholecystectomy (LC) being the preferred method. Percutaneous transhepatic gallbladder drainage (PTGBD) is considered as a safe alternative therapeutic option for resolving acute cholecystitis in surgically high-risk patients. We evaluated the surgical outcomes of acute cholecystitis, focusing on the differences between emergent LC without PTGBD, and scheduled LC following PTGBD.

Methods

Between March 2010 and December 2014, 294 patients with acute cholecystitis who had undergone LC, were retrospectively studied. Group I included 166 patients who underwent emergency LC without PTGBD. Group II included 128 patients who underwent scheduled LC after PTGBD. Clinical outcomes were analyzed according to each group.

Results

On admission, Group II had a higher mean level of c-reactive protein than Group I. According to the classification of the American Society of Anesthesiologists (ASA), group II had a greater number of high-risk patients than group I. There was no significant difference on perioperative outcomes between the two groups, including open conversion rate and complications. Analysis as per the ASA classes revealed no statistically remarkable finding between the groups.

Conclusions

There are no significant differences in the surgical outcomes of emergency LC group without PTGBD, and scheduled LC group following PTGBD. Comparison between two groups according to ASA classification reflecting the comorbidity and severity of condition of the patients also revealed no significant differences. However, scheduled LC following PTGBD is important for patients having acute cholecystitis with concurrent comorbidity.

Emergency Versus Delayed Cholecystectomy After Percutaneous Transhepatic Gallbladder Drainage in Grade II Acute Cholecystitis Patients

INTRODUCTION

In grade II acute cholecystitis patients presenting more than 72 h after onset of symptoms, we prospectively compared treatment with emergency (ELC) to delayed laparoscopic cholecystectomy performed 6 weeks after percutaneous transhepatic gallbladder drainage (PTGBD).

METHODS

Four hundred ninety-five patients with acute cholecystitis were assessed for eligibility; 345 were excluded or declined to participate. One hundred fifty patients were treated after consent with either ELC or PTGBD.

RESULTS

Both PTGBD and ELC were able to resolve quickly cholecystitis sepsis. ELC patients had a significantly higher conversion rate (24 vs. 2.7 %, P < 0.001), longer mean operative time (87.8 ± 33.06 vs. 38.09 ± 8.23 min, P < 0.001), higher intraoperative blood loss (41.73 ± 51.09 vs. 26.33 ± 23.86, P = 0.008), and longer duration of postoperative hospital stay (51.71 ± 49.39 vs. 10.76 ± 5.75 h, P < 0.001) than those in the PTGBD group. Postoperative complications were significantly more frequent in the ELC group (26.7 vs. 2.7 %, P < 0.001) with a significant increase in incidence (10.7 %) of bile leak (P = 0.006) compared to those in the PTGBD group.

CONCLUSION(S)

PTGBD and ELC are highly efficient in resolving cholecystitis sepsis. Delayed cholecystectomy after PTGBD produces better outcomes with a lower conversion rate, fewer procedure-related complications, and a shorter hospital stay than emergency cholecystectomy.

Outcomes in Older Patients with Grade III Cholecystitis and Cholecystostomy Tube Placement: A Propensity Score Analysis

BACKGROUND

The Tokyo Guidelines recommend initial cholecystostomy tube drainage, antibiotics, and delayed cholecystectomy in patients with grade III cholecystitis.

STUDY DESIGN

We used Medicare data (1996 to 2010) to identify patients 66 years and older who were admitted with grade III acute cholecystitis. We evaluated adherence to the Tokyo Guidelines and compared mortality, readmission, and complication rates with and without cholecystostomy tube placement in a propensity-matched (1:3) cohort of patients with grade III cholecystitis.

RESULTS

There were 8,818 patients admitted with grade III cholecystitis; 565 patients (6.4%) had a cholecystostomy tube placed. Cholecystostomy tube placement increased from 3.9% to 9.7% during the study period. Compared with 1,689 propensity-matched controls, patients with cholecystostomy tube placement had higher 30-day (hazard ratio [HR] = 1.26; 95% CI 1.05 to 1.50), 90-day (HR = 1.26; 95% CI 1.08 to 1.46), and 2-year mortality (HR = 1.19; 95% CI 1.04 to 1.36) and were less likely to undergo cholecystectomy in the 2 years after initial hospitalization (33.4% vs 64.4%; HR = 0.26; 95% CI 0.21 to 0.31). Readmissions were also higher at 30 days (HR = 2.93; 95% CI 2.12 to 4.05), 90 days (HR = 3.48; 95% CI 2.60 to 4.64), and 2 years (HR = 3.08; 95% CI 2.87 to 4.90).

CONCLUSIONS

Since the introduction of the Tokyo Guidelines (2007), use of cholecystostomy tubes in patients with grade III cholecystitis has increased, but the majority of patients do not get cholecystostomy tube drainage as first-line therapy. Cholecystostomy tube placement was associated with lower rates of definitive treatment with cholecystectomy, higher mortality, and higher readmission rates. These data suggest a need for additional evaluation and refinement of the Tokyo Guidelines.

International collaborative study on EUS-guided gallbladder drainage: Are we ready for prime time?

BACKGROUND

Cholecystectomy remains the gold standard treatment of cholecystitis. Endoscopic treatment of cholecystitis includes transpapillary gallbladder drainage. Recently, endoscopic ultrasound-guided transmural drainage of the gallbladder (EUS-GBD) has been reported. This study reports the cumulative experience of an international group performing EUS-GBD.

METHODS

Cases of EUS-GBD from January 2012 to November 2013 from 3 tertiary-care institutions were captured in a registry. Patient demographics, disease characteristics, procedural and clinical outcomes were recorded.

RESULTS

35 patients (15 malignant, 20 benign) were included. Median age was 81 years (SD=13.76 years), sixteen (46%) were males. Median follow-up was 91.5 days (SD=157 days). Transmural access was obtained from the stomach (n=17) or duodenum (n=18). Stents placed included plastic (n=6), metal (n=20), or combination (n=7). Technical success was achieved in 91.4% (n=32). Immediate adverse events (14%) included: bleeding, stent migration, cholecystitis and hemoperitoneum. Delayed adverse events (11%) included abscess formation and recurrence of cholecystitis. Long-term clinical success rate was 89%. Stent type and puncture site were not associated with immediate (p=0.88, p=0.62), or long-term (p=0.47, p=0.27) success.

CONCLUSIONS

EUS-GBD appears to be feasible, safe, and effective. Prospective studies are needed to confirm these findings and identify the best technique to use.

Long-Term Outcomes of Patients with Acute Cholecystitis after Successful Percutaneous Cholecystostomy Treatment and the Risk Factors for Recurrence: A Decade Experience at a Single Center

BACKGROUND

Percutaneous cholecystostomy tube (PCT) has been effectively used for the treatment of acute cholecystitis (AC) for patients unsuitable for early cholecystectomy. This retrospective study investigated the recurrence rate after successful PCT treatment and factors associated with recurrence.

METHODS

We reviewed patients treated with PCT for AC from October 2004 through December 2013. Patients with successful PCT treatment were those who were free from persistent PCT drainage. We used multivariable logistic regression analysis sequentially to identify factors associated with each outcome.

RESULTS

The study included 184 patients (mean age: 70.1 years). The average duration for parenteral antibiotics was 14.4 days and 20.0 days for PCT drainage. The one-year recurrence rate was 9.2% (17/184) with most recurrences occurring within two months (6.5%, 12/184) of the procedure. Complicated cholecystitis (odds ratio [OR]: 4.67; 95% confidence interval [CI]: 1.44-15.70; P = 0.01) and PCT drainage duration >32 days (OR: 4.92; 95% CI: 1.03-23.53; P = 0.05) positively correlated with one-year recurrence; parenteral antibiotics duration >10 days (OR: 0.21; 95% CI: 0.05-0.68; P = 0.01) was inversely associated with one-year recurrence.

CONCLUSIONS

The recurrence rate was low for patients after successful PCT treatment. Predictors for recurrence included the severity of initial AC and subsequently provided treatments.

EUS-guided gallbladder drainage with a lumen-apposing metal stent (with video)

BACKGROUND AND AIMS

Nonsurgical techniques for gallbladder drainage are percutaneous, and endoscopic. EUS-guided transmural gallbladder drainage (EUS-GBD) is a relatively new approach, although data are limited. Our aim was to describe the outcome after EUS-GBD with a lumen-apposing metal stent (LAMS).

PATIENTS AND METHODS

This was a retrospective review of prospectively collected data on 15 nonsurgical patients who underwent EUS-GBD for various indications. Procedures were performed at 3 tertiary care centers with expertise in the management of complex biliary problems. The main outcome measures were technical and clinical success and adverse events.

RESULTS

Fifteen patients (8 male, 7 female) with a median age of 74 years (range 42-89) underwent EUS-GBD by using a LAMS to decompress the gallbladder (7 patients calculous cholecystitis, 4 acalculous cholecystitis, 2 patients biliary obstruction, 1 patient gallbladder hydrops, 1 patient symptomatic cholelithiasis). Patients were nonsurgical candidates according to the American Society of Anesthesiologists Physical Status Classification System; findings were class IV or higher in 9 patients and advanced malignancies in 6. Percutaneous transhepatic gallbladder drainage (PT-GBD) was refused by all patients and was further precluded by perihepatic ascites in 3 patients, coagulopathy or need for anticoagulation in 4 patients, and need for internal biliary drainage in 2 patients. Transduodenal access and stenting was achieved in 14 of 15 patients and transgastric stenting was achieved in 1. Technical success was achieved in 14 of 15 patients (93%), whereas clinical success was achieved in all 15 patients with a median follow-up of 160 days. One mild adverse event (postprocedure fever for 3 days) was noted. The limitations of this study are the small select group of patients and retrospective study design.

CONCLUSIONS

EUS-GBD with a LAMS is technically safe and effective for decompressing the gallbladder for cholecystitis and biliary or cystic duct obstruction in patients who are poor surgical candidates.

Percutaneous cholecystostomy versus laparoscopic cholecystectomy in patients with acute cholecystitis and failed conservative management: a matched-pair analysis

INTRODUCTION

The role of percutaneous cholecystostomy (PC) or laparoscopic cholecystectomy (LC) in the management of patients with acute cholecystitis presenting beyond 72 hours from the onset of symptoms is unclear and undefined. The aim of this study was to examine and compare the outcomes of PC or LC in the management of these patients, who failed 24 hours of initial nonoperative management.

PATIENTS AND METHODS

A retrospective chart review between January 1999 and October 2010 revealed 261 patients with acute calculus cholecystitis beyond 72 hours from onset of symptoms who failed initial nonoperative management. Twenty-three of 261 (8.8%) underwent PC and were compared with a similar 1:1 matched cohort of LC, matched using sex, age, race, BMI, diabetes, and sepsis to minimize the influence of treatment selection bias.

RESULTS

There was no significant difference between PC versus LC regarding morbidity [4/23 (17%) vs. 2/23 (9%), P=0.665] and mortality [3/23 (13%) vs. 0/23 (0%), P=0.233]. The length of hospital stay was significantly longer in the PC group (15.9±12.6 vs. 7.6±4.9 d, P=0.005).

CONCLUSION

In this matched cohort analysis, PC failed to show a significant reduction in morbidity compared with LC and was associated with a significantly longer hospital stay.

Clinical outcome for laparoscopic cholecystectomy in extremely elderly patients

PURPOSE

Extremely elderly patients who present with complicated gallstone disease are less likely to undergo definitive treatment. The use of laparoscopic cholecystectomy (LC) in older patients is complicated by comorbid conditions that are concomitant with advanced age and may increase postoperative complications and the frequency of conversion to open surgery. We aimed to evaluate the results of LC in patients (older than 80 years).

METHODS

We retrospectively analyzed 302 patients who underwent LC for acute cholecystitis between January 2011 and December 2013. Total patients were divided into three groups: group 1 patients were younger than 65 years, group 2 patients were between 65 and 79 years, and group 3 patients were older than 80 years. Patient characteristics were compared between the different groups.

RESULTS

The conversion rate was significantly higher in group 3 compared to that in the other groups. Hematoma in gallbladder fossa and intraoperative bleeding were higher in group 3, the difference was not significant. Wound infection was not different between the three groups. Operating time and postoperative hospital stay were significantly higher in group 3 compared to those in the other groups. There was no reported bile leakage and operative mortality. Preoperative percutaneous transhepatic gallbladder drainage and endoscopic retrograde cholangiopancreatography were performed more frequently in group 3 than in the other groups.

CONCLUSION

LC is safe and feasible. It should be the gold-standard approach for extremely elderly patients with acute cholecystitis.

Acute acalculous cholecystitis in the critically ill: risk factors and surgical strategies

PURPOSE

Acute acalculous cholecystitis (AAC) is characterized by severe gallbladder inflammation without cystic duct obstruction. Critical illness and neurological deficits are often associated with AAC, and early radiologic imaging is necessary for the detection and timely treatment of AAC. In critically ill patients, effective surgical management is difficult. This review examines the three common surgical treatments for AAC (open cholecystectomy (OC), laparoscopic cholecystectomy (LC), or percutaneous cholecystostomy (PC)), their prevalence in current literature, and the perioperative outcomes of these different approaches using a large retrospective database.

MATERIALS AND METHODS

This review examined literature gathered from PubMed and Google Scholar to select more than 50 sources with data pertinent to AAC; of which 20 are described in a summary table. Outcomes from our previous research and several updated results were obtained from the University HealthSystem Consortium (UHC) database.

RESULTS

LC has proven effective in treating AAC when the risks of general anesthesia and the chance for conversion to OC are low. In critically ill patients with multiple comorbidities, PC or OC may be the only available options. Data in the literature and an examination of outcomes within a national database indicate that for severely ill patients, PC may be safer and met with better outcomes than OC for the healthier set of AAC patients.

CONCLUSIONS

We suggest a three-pronged approach to surgical resolution of AAC. Patients that are healthy enough to tolerate LC should undergo LC early in the course of the disease. In critically ill patients, patients with multiple comorbidities, a high conversion risk, or who are poor surgical candidates, PC may be the safest and most successful intervention.

Endoscopic ultrasound-guided gallbladder drainage for the management of acute cholecystitis (with video)

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has been introduced as an alternative to percutaneous transhepatic gallbladder drainage for the treatment of acute cholecystitis in non-surgical candidates. A systematic review of the English language literature through PubMed search until June 2014 was conducted. One hundred and fifty-five patients with acute cholecystitis treated with EUS-GBD in eight studies and 12 case reports, and two patients with EUS-GBD for other causes were identified. Overall, technical success was obtained in 153 patients (97.45%) and clinical success in 150 (99.34%) patients with acute cholecystitis. Adverse events developed in less than 8% of patients, all of them managed conservatively. EUS-GBD has been performed with plastic stents, nasobiliary drainage tubes, standard or modified tubular self-expandable metal stents (SEMS) and lumen-apposing metal stents (LAMS) by different authors with apparently similar outcomes. No comparison studies between stent types for EUS-GBD have been reported. EUS-GBD is a promising novel alternative intervention for the treatment of acute cholecystitis in high surgical risk patients. Feasibility, safety and efficacy in published studies from expert centers are very high compared to currently available alternatives. Further studies are needed to establish the safety and long-term outcomes of this procedure in other practice settings before EUS-GBD can be widely disseminated.

Acute acalculous cholecystitis immediately after gastric operation: Case report and literatures review

Acute acalculous cholecystitis (AAC) is a rare complication of gastric surgery. The most commonly accepted concepts regarding its pathogenesis are bile stasis, sepsis and ischemia, but it has not been well described how to identify and manage this disease in the early stage. We report three cases of AAC in elderly patients immediately after gastric surgery, which were treated with three different strategies. One patient died 42 d after emergency cholecystectomy, and the other two finally recovered through timely cholecystostomy and percutaneous transhepatic gallbladder drainage, respectively. These cases informed us of the value of early diagnosis and proper treatment for perioperative AAC after gastric surgery. We further reviewed reported cases of AAC immediately after gastric operation, which may expand our knowledge of this disease.

Spontaneous rupture of the gall bladder: an unusual forensic diagnosis

Peritonitis secondary to spontaneous rupture/perforation of the gall bladder is a rare condition overall and is even less common in the forensic population. We report the case of a middle-aged man who died from generalized peritonitis from gall bladder perforation due to acute acalculous cholecystitis. This condition usually occurs in critical patients with systemic illness, and although the exact pathogenesis remains unclear, the development of acalculous cholecystitis appears to be multifactorial. Antemortem diagnosis is reliant upon clinical presentation, laboratory data, and radiologic studies. Surgery and appropriate antibiotics are mainstays of treatment; however, there is an emerging role for minimally invasive procedures. Histopathologic features show significant overlap with the calculous type. Although increasing numbers of acalculous cholecystitis have been diagnosed in the critically ill, the fatal presentation of a perforated gall bladder following an undiagnosed case of acute acalculous cholecystitis is unusual in a nonhospitalized and ambulatory man.

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.

Percutaneous cholecystostomy for acute cholecystitis in patients with high comorbidity and re-evaluation of treatment efficacy

BACKGROUND

In high-risk and unfit-for-surgery patients with acute cholecystitis (AC), treatment options are controversial. Few studies have reported the results of long-term follow-up. This study aimed to evaluate the clinical course of patients after removal of the percutaneous cholecystostomy (PC) catheter in high-risk patients with AC, time interval to relapse, and factors influencing relapse.

METHODS

From 2000 to 2011, 183 patients with AC underwent PC and catheter removal in Seoul National University Hospital and Boramae Hospital, Korea. Sixty cases were reviewed retrospectively after excluding cases with intended interval cholecystectomy, malignant biliary obstruction, loss to follow-up, and insufficient follow-up information.

RESULTS

The mean age was 68.6 ± 13.8 years, and the mean Karnofsky performance score was 24.8 ± 9.7. After insertion of a PC catheter, symptom resolution and improvement on imaging were achieved in 95% and 97.9% of patients, respectively. Laboratory values were also improved (P < .01). There was no mortality during admission; 2 patients (3.3%) experienced complications during removal of the PC catheter. Relapse was observed in 7 patients (11.7%) during a median follow-up of 38.1 ± 24.8 months. There were no differences in clinical, laboratory, or imaging findings between relapsing and nonrelapsing patients. Therefore, prediction of relapse was not possible.

CONCLUSION

Among high-risk patients with AC, 88.3% were managed with PC without relapse within a median follow-up period of 38.1 months, despite radiologically severe AC in some patients. We conclude that a temporary PC can be a first-line treatment for AC without interval cholecystectomy.

Changing trends and outcomes in the use of percutaneous cholecystostomy tubes for acute cholecystitis

BACKGROUND

Percutaneous cholecystostomy tube (PCT) placement serves as a treatment option for acute cholecystitis in elderly and critically ill patients. The objective of this study was to compare PCT and cholecystectomy outcomes over time.

METHODS

PCTs placed from April 1, 1998, to December 31, 2009 (time period 2) were retrospectively reviewed. Patients who underwent cholecystectomies served as matched controls. Institutional data from March 1, 1989, to March 31, 1998 (time period 1) were reviewed to compare trends.

RESULTS

A total of 143 patients successfully underwent PCT placement in time period 2. When compared with patients undergoing cholecystectomy, PCT patients had a higher rate of cardiovascular disease (66% vs 26%, P = 0.001), diabetes (27% vs 13%, P = 0.001), and a higher mean Charlson comorbidity index (3.27 vs 1.07, P = 0.001). Compared with the first time period, patients undergoing PCT in the second time period had lower American Society of Anesthesiologist's classifications (American Society of Anesthesiologist's class I, II: 0% vs 18%, P = 0.001). Thirty-day mortality decreased from 36% to 12% in patients undergoing PCT (P = 0.001).

CONCLUSIONS

Among patients with acute cholecystitis, percutaneous cholecystostomy tubes were placed in older patients with increased comorbidities compared to cholecystectomy. Mortality rates after PCT decreased over time.

TG13 indications and techniques for gallbladder drainage in acute cholecystitis (with videos)

Percutaneous transhepatic gallbladder drainage (PTGBD) is considered a safe alternative to early cholecystectomy, especially in surgically high-risk patients with acute cholecystitis. Although randomized prospective controlled trials are lacking, data from most retrospective studies demonstrate that PTGBD is the most common gallbladder drainage method. There are several alternatives to PTGBD. Percutaneous transhepatic gallbladder aspiration is a simple alternative drainage method with fewer complications; however, its clinical usefulness has been shown only by case-series studies. Endoscopic naso-gallbladder drainage and gallbladder stenting via a transpapillary endoscopic approach are also alternative methods in acute cholecystitis, but both of them have technical difficulties resulting in lower success rates than that of PTGBD. Recently, endoscopic ultrasonography-guided transmural gallbladder drainage has been reported as a special technique for gallbladder drainage. However, it is not yet an established technique. Therefore, it should be performed in high-volume institutes by skilled endoscopists. Further prospective evaluations of the feasibility, safety, and efficacy of these various approaches are needed. This article describes indications and techniques of drainage for acute cholecystitis.Free full-text articles and a mobile application of TG13 are available via http://www.jshbps.jp/en/guideline/tg13.html.

Outcome after percutaneous cholecystostomy for acute cholecystitis: a single-center experience

BACKGROUND

Percutaneous cholecystostomy is an alternative treatment for acute cholecystitis patients with high surgical risk.

METHODS

One hundred and sixty-six patients consecutively treated by percutaneous cholecystostomy for acute cholecystitis in a single medical center were retrospectively reviewed.

RESULTS

The cohort included 121 males and 45 females with mean age of 75.9 years. The overall inhospital mortality rate was 15.1 % (n = 25). Elevated serum creatinine level at diagnosis [odds ratio (OR) 1.497; p = 0.020], septic shock (OR 11.755; p = 0.001), and development of cholecystitis during admission (OR 7.256; p = 0.007) were predictive of inhospital mortality. Of 126 patients who recovered from calculous cholecystitis, 11 experienced recurrent cholecystitis within 2 months. Serum C-reactive protein (CRP) level >15 mg dl(-1) at diagnosis [hazard ratio (HR) 10.141; p = 0.027] and drainage duration of cholecystostomy longer than 2 weeks (HR 3.638; p = 0.039) were independent risk factors of early recurrence. The 53 patients who underwent cholecystectomy had an 18.9 % perioperative complication rate and no operation-related mortality.

CONCLUSIONS

In-patients or those with septic shock or renal insufficiency have worse outcome. Prolonged drainage duration and high CRP level predict early recurrence. Removal of the drainage tube is recommended after resolution of the acute illness.

Endoscopic ultrasound-guided transmural and percutaneous transhepatic gallbladder drainage are comparable for acute cholecystitis

BACKGROUND & AIMS

Endoscopic ultrasound-guided transmural gallbladder drainage (EUS-GBD) is an alternative to percutaneous transhepatic gallbladder drainage (PTGBD) for patients with acute, high-risk, or advanced-stage cholecystitis who do not respond to initial medical treatment and cannot undergo emergency cholecystectomy. However, the technical feasibility, efficacy, and safety of EUS-GBD and PTGBD have not been compared.

METHODS

Fifty-nine patients with acute cholecystitis, who did not respond to initial medical treatment and were unsuitable for an emergency cholecystectomy, were chosen randomly to undergo EUS-GBD (n = 30) or PTGBD (n = 29). The technical feasibility, efficacy, and safety of EUS-GBD and PTGBD were compared.

RESULTS

EUS-GBD and PTGBD showed similar technical (97% [29 of 30] vs 97% [28 of 29]; 95% 1-sided confidence interval lower limit, -7%; P = .001 for noninferiority margin of 15%) and clinical (100% [29 of 29] vs 96% [27 of 28]; 95% 1-sided confidence interval lower limit, -2%; P = .0001 for noninferiority margin of 15%) success rates, and similar rates of complications (7% [2 of 30] vs 3% [1 of 29]; P = .492 in the Fisher exact test) and conversions to open cholecystectomy (9% [2 of 23] vs 12% [3 of 26]; P = .999 in the Fisher exact test). The median post-procedure pain score was significantly lower after EUS-GBD than after PTGBD (1 vs 5; P < .001 in the Mann-Whitney U test).

CONCLUSIONS

EUS-GBD is comparable with PTGBD in terms of the technical feasibility and efficacy; there were no statistical differences in the safety. EUS-GBD is a good alternative for high-risk patients with acute cholecystitis who cannot undergo an emergency cholecystectomy.

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.
