Endoscopic management of hepatic hydatid cyst with biliary communication

Cystic echinococcosis of the liver in Kazakhstan: The effectiveness of the PAIR method in comparison with laparoscopic and open surgical methods

BACKGROUND

One of the urgent problems of surgical parasitology in the Republic of Kazakhstan is liver cystic echinococcosis. The study aimed to analyze the effectiveness and safety of the percutaneous treatment with different techniques in comparison with the results of laparoscopic and "open" surgical methods.

METHODS

Retrospectively, we analyzed the outcome of 485 patients with active echinococcal cysts in the period from January 2017-July 2023. Indications for surgical treatment and the choice of the intervention method were based on this classification. Patients were conditionally divided into 3 groups: Laparoscopy-33, Laparotomy-319, PAIR-133.

RESULTS

The duration of the operation in the PAIR was significantly shorter compared to the Laparotomy and Laparoscopy groups (55.4vs.225.2 and 215.3, p = 0.0001). There was no intraoperative blood loss in PAIR, whereas in Laparotomy and Laparoscopy there were 146.0 and 111.0. The postoperative stay of patients in PAIR is significantly shorter than in Laparotomy and Laparoscopy (3.8 compared to 7.5 and 6.4, p = 0.0001). The follow-up time averaged 39.8 months ± 21. There were no statistically significant differences in relapses. Laparotomy and PAIR groups had 11 (3.5 %) and 6 (4.5 %) relapses, respectively.

CONCLUSION

In cystic echinococcosis of the liver types CE1, CE3a regardless of the localization, the optimal volume is a PAIR is characterized by a shorter postoperative stay of the patient, early recovery and cure. In the CE2, CE3b stages, laparoscopic pericystectomy is the most effective and safe in individual patients. In case of an intimate arrangement of cysts to tubular structures, the safest method is laparotomy.

Endoscopic definitive treatment of liver hydatid cysts ruptured into bile duct

BACKGROUND

Intrabiliary rupture (IBR) is one of the most common complications of hepatic hydatid cysts (HHC),and the surgical treatment of major intrabiliary rupture (MIBR) leads to serious morbidity and mortality. This study aimed to evaluate the efficacy of endoscopic definitive treatment of these patients.

METHODS

This study included 38 patients who underwent ERCP for MIBR between 2004 and 2022. Endoscopic sphincterotomy (ES) was performed, followed by evacuation of hydatid contents from the main bile ducts and cyst cavity. A nasobiliary drainage (NBD) catheter was placed inside the cyst cavity in 15 patients, while biliary stenting (BS) was performed in 23 patients. Demographic data, cyst characteristics, hospital stay, complications, treatment success, and recurrence were analyzed.

RESULTS

The mean age of patients was 46.5 years, with 12 female and 26 male. All patients had WHO-type-3B hydatid cysts with an average diameter of 7.9 cm. NBD was continued for definitive purposes in 13 of the 15 patients who underwent NBD, and full cure was achieved in 13 patients. Among the 23 patients who underwent biliary stenting (BS), 16 (69.5%) required a second ERCP due to jaundice or cholangitis, and 6 (26%) underwent percutaneous drainage due to hydatid cavity infection. The average length of hospital stay was 16.13 days in the BS group, while it was 8.3 days in the NBD group.The average follow-up period was 23 months. All patients achieved complete recovery.

CONCLUSIONS

The endoscopic approach is an effective and safe method for the treatment of MIBR, and can be considered as a definitive treatment option in centers with adequate resources and experienced endoscopists.

A Novel Technique for the Management of Persistent Biliary Fistulas Developing After Liver Hydatid Cyst Surgeries: Drain Clamping Technique

BACKGROUND

External biliary fistula, where the residual cyst is associated with the biliary tree, is one of the most common complications after liver hydatid cyst surgery. Surgical procedures become a consideration for patients in whom the biliary fistula persists despite all endoscopic procedures. However, reoperation for biliary fistula after hydatid cyst surgery leads to additional complications and increases morbidity and mortality.

AIM

This study aims to treat persistent biliary fistulas that develop after liver hydatid cyst surgery using a simple noninvasive technique.

MATERIALS AND METHODS

External drainage surgery was performed on 295 patients with liver hydatid cysts. Endoscopic treatment methods were used in patients who developed biliary fistula after surgery. Despite all endoscopic treatment methods, 14 patients developed persistent biliary fistulas. These patients were subsequently treated using the drain clamping technique.

FINDINGS

All persistent fistulas occluded in 11.86 days (with a range of 8-20 days). No complications were observed in the one-year follow-up visits.

CONCLUSION

Drain clamping, a novel approach to the treatment of persistent biliary fistulas developed despite all available endoscopic methods, can be safely used. This technique resulted in a complete recovery in patients without the need for surgical procedures.

Cholangiohydatidosis. Clinical features, postoperative complications and hospital mortality. A systematic review

BACKGROUND

Cholangiohydatidosis (CH) is an evolutionary complication of hepatic cystic echinococcosis, associated with increased morbidity and mortality. The aim of this study was to describe the available evidence regarding clinical characteristics of CH, postoperative complications and hospital mortality.

METHODOLOGY/PRINCIPAL FINDINGS

Systematic review. Studies related to CH with no language or publication restriction were included. Sensitive searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS. MeSH and free terms were used, including articles up to April 2023. The main outcome variables were postoperative complications and hospital mortality; the secondary ones were publication year, origin and design of primary studies, main clinical manifestation, anatomical location and type of cysts, hospital stay, surgical procedure performed, reinterventions; and methodological quality of primary studies, which was assessed using MInCir-T and MInCir-P scales. Descriptive statistics, calculation of weighted averages and their comparison by least squares logistic regression were applied. 446 studies were retrieved from the searches performed, 102 of which met the inclusion and exclusion criteria. The studies analyzed represent 1241 patients. The highest proportion of articles was published in the last decade (39.2%). Reports are mainly from Turkey (28.4%), Greece (9.8%), Morocco and Spain (8.8% each). With a weighted mean of 14.3 days of hospital stance; it was verified that 26.2% of patients developed postoperative complications (74,3% Clavien y Dindo III y IV), 6.7% needed re-interventions, and 3.7% died. When comparing the variables age, postoperative complications, hospital mortality, and reinterventions in two periods of time (1982-2006 vs. 2007-2023), no statistically significant differences were found. When applying the MInCir-T and MInCir-P scales, the methodological quality of the primary studies was 9.6±1.1 and 14.5±4.3 points, respectively.

CONCLUSION/SIGNIFICANCE

CH is associated with severe postoperative complications and significant hospital mortality, independent of the development of therapeutic support associated with the passage of time.

ERCP management of acute cholangitis caused by rupture of Echinococcus hepaticus into the biliary tract

Background

Hepatic cystic echinococcosis (HCE) rupture into the biliary tract, one of the most common and refractory complications, is treated by laparotomy to remove hydatid lesions. The aim of this article was to investigate the role of endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of this particular disease.

Patients and Methods

This was is a retrospective analysis of 40 patients with HCE ruptured into the biliary tract in our hospital from September 2014 to October 2019. They were divided into two groups, ERCP group (group A, n = 14) and conventional surgery group (group B, n = 26). Group A was treated with ERCP first to control infection and improve the general condition before undergoing laparotomy at an optional stage while group B was treated with laparotomy directly. First, the infection parameters and liver, kidney and coagulation functions of group A patients before and after ERCP were compared to evaluate treatment effectiveness. Second, the intraoperative and post-operative parameters during the laparotomy of group A were compared with group B to evaluate the impact of ERCP treatment on laparotomy.

Results and Conclusions

White blood cell, NE%, platelet, procalcitonin, C-reactive protein, interleukin-6, Total bilirubin (TBIL), alkaline phosphatase, gamma-glutamyl transpeptidase, aspartate transaminase, alanine transaminase (ALT), ALT and Cr in group A significantly improved by ERCP (P < 0.05); during laparotomy, the bleeding amount and hospital stay in group A were better (P < 0.05); moreover, concerning the post-operative complications, the incidence of acute renal failure and coagulation dysfunction in group A was significantly less (P < 0.05). ERCP, which not only quickly and effectively controls infection and improves the patient's systemic condition but also provides good support for subsequent radical surgery, enjoys good prospects for clinical application.

Treatment of Hepatic Hydatid Disease: Role of Surgery, ERCP, and Percutaneous Drainage: A Retrospective Study

INTRODUCTION

Failure to follow the World Health Organization's Informal Working Group on Echinococcosis guidance or having limited experience in the management of cystic echinococcosis (CE) in endemic or nonendemic areas of the world may lead to risky unnecessary procedures.

MATERIALS AND METHODS

Medical records of all patients undergoing surgery for hepatic hydatid disease at the gastroenterologic surgery and general surgery departments of our hospital between December 2014 and October 2019 were collected and reviewed retrospectively. Demographic characteristics, the size and number of the cysts preoperative liver function tests, surgical treatment, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous drainage (PD), morbidity, and treatment outcomes were reviewed.

RESULTS

Of 122 patients included in the study, 77 (63, 1%) were female and 45 (36, 9%) were male individuals and their mean age was 44.95 years. CE1 was identified in 13 patients (10.6%) CE2 in 66 patients (54.1%), CE3a in 7 patients (5.8%), CE3b in 28 patients (22.9%), and CE4 in 8 patients (6.6%). Twenty patients (16.4%) with a cystobiliary fistula in the liver, obstructive jaundice, and postoperative bile leak underwent ERCP. PD was performed in patients with fluid in the hepatic hydatid cyst pouch, increased pouch size because of bile collection, and clinical symptoms postoperatively. Patients presenting with persistent bile leak despite PD underwent ERCP and were treated with endoscopic sphincterotomy and stent placement. Patients with PD were followed by keeping the percutaneous drain open and closed for a while to create pressure difference in the cyst pouch after ERCP. The percutaneous drain was removed in the next 14 to 21 days after checking the pouch size, whereas the common bile duct stents were removed 2 months later after performing a follow-up cholangiography.

CONCLUSIONS

ERCP should be the primary method for the diagnosis and treatment for hepatic hydatid cysts ruptured into the ducts. İn some cases, high-flow hydatid cysts with rupture into the bile ducts or persistent biliary fistulas can be treated with ERCP and endoscopic sphincterotomy, biliary stent, PD, and nasobiliary drainage without the need for surgical intervention.

Outcomes of Endoscopic Management among Patients with Bile Leak of Various Etiologies at a Tertiary Care Center

BACKGROUND/AIMS

Bile leak is a common complication of cholecystectomy, and it is also observed in other conditions such as ruptured liver abscess, hydatid cyst, and trauma. Endoscopic retrograde cholangiopancreatography (ERCP) is the first-line management for such conditions. However, studies on the outcomes of endoscopic management for bile leaks with etiologies other than post-cholecystectomy injury are extremely limited.

METHODS

We conducted a retrospective review of patients with symptomatic bile leak who were referred to a tertiary care center and who underwent ERCP between April 2016 and April 2019. The primary outcome was complete symptomatic resolution without extravasation of the contrast medium during the second ERCP conducted after 6 weeks.

RESULTS

In total, 71 patients presented with symptomatic bile leak. The etiologies of bile leak were post-cholecystectomy injury in 34 (47.8%), liver abscess in 20 (28.1%), and post-hydatid cyst surgery in 11 (15.4%) patients. All patients were managed with ERCP, sphincterotomy, and stent placement for 6 weeks, except for one who underwent surgery. The primary outcome was achieved in 65 (91.5%) of 71 patients. There was no significant difference in terms of outcome in relation to the interval between the diagnosis of bile leak and ERCP.

CONCLUSION

Most patients with bile leak can be successfully managed with ERCP even when performed on an elective basis.

Cholecysto-Hydatid Cyst Fistula: A Rare Cause of Cholangitis

Specialty: Surgery

A retrospective analysis of endoscopic treatment outcomes in patients with postoperative bile leakage

OBJECTIVE:

Bile leakage, while rare, can be a complication seen after cholecystectomy. It may also occur after hepatic or biliary surgical procedures. Etiology may be underlying pathology or surgical complication. Endoscopic retrograde cholangiopancreatography (ERCP) can play major role in diagnosis and treatment of bile leakage. Present study was a retrospective analysis of outcomes of ERCP procedure in patients with bile leakage.

METHODS:

Patients who underwent ERCP for bile leakage after surgery between 2008 and 2012 were included in the study. Etiology, clinical and radiological characteristics, and endoscopic treatment outcomes were recorded and analyzed.

RESULTS:

Total of 31 patients (10 male, 21 female) were included in the study. ERCP was performed for bile leakage after cholecystectomy in 20 patients, after hydatid cyst operation in 10 patients, and after hepatic resection in 1 patient. Clinical signs and symptoms of bile leakage included abdominal pain, bile drainage from percutaneous drain, peritonitis, jaundice, and bilioma. Twelve (60%) patients were treated with endoscopic sphincterotomy (ES) and nasobiliary drainage (NBD) catheter, 7 patients (35%) were treated with ES and biliary stent (BS), and 1 patient (5%) was treated with ES alone. Treatment efficiency was 100% in bile leakage cases after cholecystectomy. Ten (32%) cases of hydatid cyst surgery had subsequent cystobiliary fistula. Of these patients, 7 were treated with ES and NBD, 2 were treated with ES and BS, and 1 patient (8%) with ES alone. Treatment was successful in 90% of these cases.

CONCLUSION:

ERCP is an effective method to diagnose and treat bile leakage. Endoscopic treatment of postoperative bile leakage should be individualized based on etiological and other factors, such as accompanying fistula.

Hepatobiliary complications of alveolar echinococcosis: A long-term follow-up study

AIM: To determine the long-term hepatobiliary complications of alveolar echinococcosis (AE) and treatment options using interventional methods.

METHODS: Included in the study were 35 patients with AE enrolled in the Echinococcus Multilocularis Data Bank of the University Hospital of Ulm. Patients underwent endoscopic intervention for treatment of hepatobiliary complications between 1979 and 2012. Patients’ epidemiologic data, clinical symptoms, and indications for the intervention, the type of intervention and any additional procedures, hepatic laboratory parameters (pre- and post-intervention), medication and surgical treatment (pre- and post-intervention), as well as complications associated with the intervention and patients‘ subsequent clinical courses were analyzed. In order to compare patients with AE with and without history of intervention, data from an additional 322 patients with AE who had not experienced hepatobiliary complications and had not undergone endoscopic intervention were retrieved and analyzed.

RESULTS: Included in the study were 22 male and 13 female patients whose average age at first diagnosis was 48.1 years and 52.7 years at the time of intervention. The average time elapsed between first diagnosis and onset of hepatobiliary complications was 3.7 years. The most common symptoms were jaundice, abdominal pains, and weight loss. The number of interventions per patient ranged from one to ten. Endoscopic retrograde cholangiopancreatography (ERCP) was most frequently performed in combination with stent placement (82.9%), followed by percutaneous transhepatic cholangiodrainage (31.4%) and ERCP without stent placement (22.9%). In 14.3% of cases, magnetic resonance cholangiopancreatography was performed. A total of eight patients received a biliary stent. A comparison of biochemical hepatic function parameters at first diagnosis between patients who had or had not undergone intervention revealed that these were significantly elevated in six patients who had undergone intervention. Complications (cholangitis, pancreatitis) occurred in six patients during and in 12 patients following the intervention. The average survival following onset of hepatobiliary complications was 8.8 years.

CONCLUSION: Hepatobiliary complications occur in about 10% of patients. A significant increase in hepatic transaminase concentrations facilitates the diagnosis. Interventional methods represent viable management options.

Role of endoscopic retrograde cholangiopancreatography in the management of hepatic hydatid disease

Most cases of hepatic hydatid disease exhibit uncomplicated clinical course and management. However, the diagnosis and management of complicated hepatic hydatid disease is a special issue. One of the most common and serious complications of hepatic hydatid disease is the rupture of the cyst into intrahepatic bile ducts. The clinical appearance of intrabiliary rupture can range from asymptomatic to jaundice, cholecystitis, cholangitis, liver abscess, pancreatitis and septicemia. Current treatments for major ruptures can result in high morbidity and mortality rates. Furthermore, ruptures that cannot be diagnosed preoperatively can induce complications such as biliary fistulae, biloma, cavitary infection and obstructive jaundice. In the past, these complications were diagnosed and treated by surgical methods. Currently, complications in both the pre- and postoperative periods are diagnosed and treated by non-invasive or minimally invasive methods. In clinical practice, endoscopic retrograde cholangiopancreatography (ERCP) is indicated for patients with preoperative frank intrabiliary rupture in which hydatid elements are clearly seen in the bile ducts, or for biliary adverse events after surgery, including persistent biliary fistulae and jaundice. However, controversy concerning routine preoperative ERCP and prophylactic endoscopic sphincterotomy in patients suspected of having minor cystobiliary communications still remains. In this article, the role of ERCP in the diagnosis and management of hepatic hydatid disease during the pre- and postoperative periods is reviewed.
