Endoscopic retrograde cholangiopancreatography in ruptured liver hydatid cyst

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.

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.

Complication of Hepatic Hydatid Cyst Surgery Presenting as Obstructive Jaundice

The liver is the commonest organ affected by hydatid disease. We report a rare case of a 25-year-old female patient who was treated surgically for hepatic echinococcosis two weeks ago with laparoscopic excision of hepatic hydatid cyst with marsupialization and omentoplasty. She then presented with features of obstructive jaundice, which is a known complication following hydatid endocystectomy. Cholangiogram revealed a communication of the residual hydatid cyst with right segmental intrahepatic biliary radicals. She was treated with endoscopic retrograde cholangiopancreatography (ERCP)-guided stenting. ERCP is regarded as an important therapeutic strategy for hydatid cysts occurring in the extra biliary tree either as primary or as complications of liver cysts. It facilitates the clearing of hydatid debris from the biliary tree, and the closure of fistulas and bile leaks followed by laparoscopic cholecystectomy when the hydatid cysts are also located in the gallbladder.

Turkish HPB Surgery Association consensus report on hepatic cystic Echinococcosis (HCE)

OBJECTIVES

Cystic Echinococcosis (CE) is one of the important problems of the Eurasian region. We aimed to prepare a consensus report in order to update the treatment approaches of this disease. This study was conducted by Turkish HPB Surgery Association.

MATERIAL AND METHODS

This study was conducted with the modified Delphi model. For this purpose, we conducted a three-stage consensus-building approach.

RESULTS

Six topics, including diagnosis, medical treatment, percutaneous treatment, surgical treatment, management of complications and posttreatment follow-up and recurrences in HCE were discussed.

CONCLUSION

The expert panel made recommendations for every topic.

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.

Use of White test to reduce bile leakage in complicated hepatic echinococcosis

BACKGROUND

Complicated hepatic echinococcosis is characterized by being multiple, large residual lumen, and secondary biliary fistula. The prevention and treatment of postoperative biliary leakage should be focused on intraoperative biliary leakage clearance. During laparoscopy, injection of a visible contrast agent into the biliary tract system is advantageous for the surgeon to remove the bile leakage point.

AIM

To analyze the postoperative complications of different surgical methods in patients with hepatic echinococcosis, and discuss the application of White test + endoscopic retrograde cholangiopancreatography (ERCP) + laparoscopy in such patients.

METHODS

A retrospective analysis was performed on 43 patients who were diagnosed with hepatic echinococcosis and treated by surgery from January 2017 to January 2019, including 15 patients undergoing laparotomy alone, 14 patients undergoing preoperative ERCP + endoscopy , and 14 patients undergoing White test + ERCP + endoscopy.

RESULTS

The incidence of short-term residual bile leakage in the White test + ERCP + endoscopy group was significantly lower than that in the laparotomy group, and the incidence of long-term (3-month) bile leakage in the White test + ERCP + endoscopy group and the ERCP + endoscopy group was significantly lower than that in the laparotomy group.

CONCLUSION

White test + ERCP + endoscopic treatment can effectively prevent the occurrence of postoperative bile leakage in patients with complicated hepatic echinococcosis.

Long-Term Results of Percutaneous Management of Liver Hydatid Cysts: - Experience of a University Hospital in Endemic Region

Background and objective: Surgery was considered for years the standard treatment for all stages of liver hydatid cysts (LHC). Percutaneous treatment has becomes a fast, reliable and more efficient method in selected cases. The purpose of this study is to evaluate the effectiveness of percutaneous treatment of LHC on the basis of our department long-term results. Patients and Methods: This study includes all patients who benefited from percutaneous treatment for LHC from December 1998 to April 2012. Puncture aspiration, injection, and re-aspiration (PAIR) were used for hydatid cysts smaller than 6 cm. Larger cysts, infected cysts and those with biliary fistula were treated by puncture associated to drainage (PA-PD). Absolute alcohol was used as sclerosing agent. Reduction of the size of the cyst more than 50%, pseudo-tumour echo pattern and disappearance of the cyst at the follow-up were retained as criteria of treatment efficacy. Results: Two hundred thirty patients (136 female and 94 male; mean age: 35 years old) with 278 LHC underwent percutaneous treatment. Mean initial cyst diameter was 76.8 mm [20-180 mm]. According to Gharbi's classification, types I and II LHC accounted for 74% and 25% respectively. Fourteen patients (6%) presented with an infected cavity and 27 patients (12%) had a biliary fistula at diagnosis (12%). PA-PD was initially performedin 23 patients. No mortality, abdominal dissemination, or tract seeding occurred. Minor complications like urticaria, cutaneous rash and fever were reported in 24 patients (10%). One case of anaphylactic shock was reported with good evolution. Mean hospitalization time was 3 days ± 1.5 for uncomplicated cases and 16.5 days± 4.2 for complicated cases. 229 out of 230 patients were cured, whereas one recurrence has been reported. Conclusion: Percutaneous treatmentis efficient and safe and offers complete cure in selected patients with the advantage of short hospitalization.
