Acute pancreatitis caused by hydatid membranes in the biliary tract: treatment with endoscopic sphincterotomy

Successful Treatment of Concurrent Cholangiohydatidosis with Obstructive Jaundice and Hepatothoracic Transit in a Pediatric Patient

Concurrent rupture of hepatic hydatid cysts into the biliary tree and into the pleural cavity is a very rare complication in echinococcosis and can pose diagnostic and treatment challenges. We present the case of a 15-year-old female patient with recurrent abdominal pain, chest pain, fever, vomiting, jaundice, and cholangitis. Ultrasound, X-rays, computed tomography of the abdomen and thorax and cholangio-magnetic resonance imaging revealed a hepatic hydatid cyst with rupture into the main biliary duct causing obstruction, gallbladder microlithiasis, rupture of the right hemidiaphragm, and pleural hydatidosis. Echinococcus serology tests were positive. Endoscopic retrograde cholangiopancreatography (ERCP) could not resolve the obstructive jaundice. A laparotomy with choledochotomy, removal of hydatid structures, choledochal drainage with Kehr tube, cholecystectomy, Lagrot partial pericystectomy, partial pleural resection, suturing of the diaphragm, and triple drainage (right pleural cavity, cystic cavity, and Douglas pouch) was performed. Perioperative albendazole and antibiotic therapy was administered. The patient had an uneventful postoperative course. Follow-up at 1, 6, 12, and 24 months showed a favorable evolution without relapse of the hydatidosis. The very rare complications of cholangiohydatidosis and concomitant hepatothoracic transit lead to a severe condition, which needs adequate surgical treatment. Clinical presentation and laboratory findings are not specific and may simulate an obstructive jaundice and acute cholangitis of other etiology. ERCP with endoscopic papillotomy offers the advantage of a minimally invasive surgery, but it does not allow a definitive treatment of the whole problem and may be useful as a bridge procedure to drain the bile duct while awaiting definitive surgery.

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.

Acute pancreatitis as an uncommon complication of hydatid cyst of the liver: A case report and systematic literature review

Hydatid disease is a major health problem worldwide. The liver is the most frequent location of hydatid disease. Acute pancreatitis secondary to liver hydatid cyst ruptured in the biliary tract is scarce and fewly described in literature. The management of this pancreatic complication of liver hydatid disease is challenging and includes a combination of surgical and endoscopic approaches. We report herein a rare case of hydatid cyst of the liver with cysto-biliary communication revealed by acute pancreatitis. A systematic literature review of similar cases reported was provided to compare surgical and endoscopic techniques. A thirty-year-old woman was referred to our emergency unit for acute pancreatitis. The CT-scan findings revealed a liver hydatid cyst ruptured in the biliary tract and daughter vesicles within were found, responsible for C-grade acute pancreatitis. We decided then to perform an emergency surgery through a bisoucostal incision. We performed a cholecystectomy and a peroperative cholangiogram that showed the communication between the cyst and left biliary tracts and the presence of daughter vesicle within the common bile duct. We conducted an exploration of the common bile duct with extraction of vesicle daughters. We left behind a T-tube in the common bile duct and we sutured the cysto-biliary fistula. Drainage was left in the remnant cavity after unroofing the cyst. Postoperative course was uneventful. Six months follow-up showed no recurrence. Cysto-biliary communication of liver hydatid disease revealed by acute pancreatitis is uncommon. We chose to perform emergency open surgery. However, through a systematic literature review, we noticed that endoscopic treatment is an efficient therapeutic and diagnostic tool to delay a morbid surgery of the liver and the common bile duct.

Infectious causes of acute pancreatitis: A systematic review

BACKGROUND

Infectious etiologies of acute pancreatitis (AP) are rare and include viruses, bacteria, mycobacteria, parasites, and fungi. We aimed to conduct a comprehensive review on infectious etiologies of AP analyzing the frequency, clinical features, and outcomes of individuals presenting with this condition.

METHODS

Eligible articles reporting on AP attributed to infectious etiologies were included. A comprehensive literature search of PubMed from time of inception and until September 6,2019 was performed using all relevant MeSH (medical subject heading) keywords. Articles were assessed for eligibility and independently reviewed by two reviewers for clinical features of AP, local complications, and mortality. Methodological quality of included studies was evaluated using the Murad tool.

RESULTS

A total of 212 articles were included, of which 168 (79.2%) were at high risk of bias. 320 cases of AP were identified. Viruses were the leading etiology of infection attributed AP (65.3%) followed by helminths (19.1%), and bacteria (12.5%). Protozoa, mycobacteria, and fungi accounted for the remaining 3.1% of cases. Mean age was 40.5 ± 18.4 years and M:F ratio was 1.94:1. Mortality occurred in 50 patients. Mortality rate was higher in the virus attributed AP patients than AP from other infectious etiologies (21.8% vs. 7.0%, p < 0.0005).

INTERPRETATION

Literature quality on infection attributed AP is limited. Virus attributed AP appears to carry a higher mortality than other etiologies of infection attributed AP.

Pancreatic Hydatid Cyst Causing Acute Pancreatitis: A Case Report and Literature Review

Hydatidosis is a public health problem in endemic countries. Hydatid cysts are located usually in the liver and the lungs. Primary pancreatic hydatid cyst is in unusual location and rarely causes acute pancreatitis. In this paper, we report a case of a 34-year-old man who admitted with recurrent acute pancreatitis. Following the preoperation investigations, the primary impression was a pancreatic pseudocyst. During surgery, a primary hydatid cyst was detected in the pancreas measuring 35 × 20 × 15 cm. The treatment consisted of evacuation and external draining of the cyst. In addition, we summarized 14 cases of primary hydatid cyst of the pancreas associated with acute pancreatitis reported in the literature.

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.

Treatment of hepatic hydatid disease complications using endoscopic retrograde cholangiopancreatography procedures

BACKGROUND

Liver hydatidosis may lead to serious morbidity due to biliary complications, the management for which endoscopic sphincterotomy (ES) and biliary drainage are very efficient. We evaluated the effectiveness of endoscopic treatment for complications of hepatic hydatid disease.

METHODS

We retrospectively reviewed endoscopic retrograde cholangiopancreatography (ERCP) procedures performed between January 2000 and December 2009 and compared laboratory findings, localization of the lesions and ERCP procedures applied between patients with and without jaundice.

RESULTS

In all, 70 ERCP procedures were performed in 54 patients (24 men, 30 women). Of the 70 procedures, 24 were performed to treat jaundice. All patients with biliary fistulas and jaundice were managed with endoscopic procedures. The 70 ERCP procedures included sphincterotomy only (n = 40); sphincterotomy and stent placement (n = 7); stent placement only (n = 4); sphincterotomy and membrane extraction (n = 9); sphincterotomy, membrane extraction and pus drainage (n = 5); and sphincterotomy and pus drainage (n = 5). Laboratory results improved in 3-7 days, and bile leakage ceased in 2-21 days.

CONCLUSION

Endoscopic retrograde cholangiopancreatography is a safe and effective way to manage biliary complications of hepatic echinococcal disease. In most patients, ES is the most efficient treatment of postoperative external biliary fistulas, jaundice and accompanying cholangitis, as it enables clearing the bile ducts of hydatid remnants; ES should be performed since it accelerates the healing process by decreasing pressure in the choledochus.

Acute pancreatitis due to pancreatic hydatid cyst: a case report and review of the literature

Hydatid disease is a major health problem worldwide. Primary hydatid disease of the pancreas is very rare and acute pancreatitis secondary to hydatid cyst has rarely been reported. We report the case of a 38-year-old man who presented acute pancreatitis. A diagnosis of hydatid cyst of the pancreas, measuring 10 cm, was established by abdominal computed tomography before surgery. The treatment consisted of a distal pancreatectomy. The postoperative period was uneventful. Additionally, a review of the literature regarding case reports of acute pancreatitis due to pancreatic hydatid cyst is presented.

Acute pancreatitis caused by impaction of hydatid membranes in the papilla of Vater: a case report

Acute pancreatitis is a rare complication of hydatidosis and the successful use of endoscopic sphincterotomy associated with extraction of hydatid membranes has been rarely reported. We describe a young man who developed acute pancreatitis after rupture of an echinococcus cyst, located at the left hepatic lobe, into the biliary tract. The cause of pancreatitis was confirmed by endoscopic retrograde cholangiopancreatography, which revealed the presence of a daughter cyst impacted in the major papilla. After sphincterotomy and removal of hydatid membranes from the biliary tract, the patient presented rapid resolution of pancreatitis and made an uneventful recovery.

Endoscopic management of a relapsing hepatic hydatid cyst with intrabiliary rupture: a case report and review of the literature

Hydatid disease, although endemic mostly in sheep-farming countries, remains a public health issue worldwide, involving mainly the liver. Intrabiliary rupture is the most frequent complication of the hepatic hydatid cyst. Endoscopy is advocated, preoperatively, to alleviate obstructive jaundice caused by intracystic materials after a frank rupture and is also a useful and well-established adjunct in locating postoperative biliary fistulas. Endoscopic retrograde cholangiography with sphincterotomy has been successful as the sole and definitive means of treatment of intrabiliary ruptured hydatid cysts. A case of an elderly woman with frank rupture is presented, where the rupture was definitively managed endoscopically in conjunction with sphincterotomy to remove the intrabiliary obstructive daughter cysts and to achieve decontamination of the biliary tree. Endoscopic retrograde cholangiography provided an excellent diagnostic and therapeutic modality in the present case and, thus, it should be considered as definitive treatment in similar cases especially if surgical risk is anticipated to be high.

[Hydatic acute pancreatitis: a case report]

Acute pancreatitis caused by hydatic cyst of the liver was rarely reported. The authors report a new case of hydatic pancreatitis characterized by visualization of hydatid membranes in the biliary tract without any biliary stone or alcoholic consumption.

Acute pancreatitis complicating intrabiliary rupture of liver hydatid cyst

Acute pancreatitis is a rare complication of hydatidosis, and the successful use of endoscopic sphincterotomy in the treatment of pancreatitis complicating ruptured hydatid cyst has been very rarely reported.We report here a case of a 50-year-old man, known to have hydatid cyst of the liver, who presented with upper abdominal pain. Amylase and lipase were elevated and echinococcus serology was positive. Abdominal CT scan showed a cystic lesion in the right lobe of the liver and a diffusely swollen pancreas with indurations around it. At endoscopic retrograde cholangiopancreatography (ERCP) the common bile duct was dilated. A sphincterotomy was performed and a mucoid structure was extracted, after which the patient made an uneventful recovery.

Biliary complications of large Echinococcus granulosus cysts: report of 2 cases and review of the literature

Hydatid cysts are often incidentally found and remain clinically silent. However complications can occur. We present 2 patients who developed biliary complications due to a large hydatid cyst. In the first patient compression on the intrahepatic bile ducts and cystic duct by the cyst, caused cholangitis and cholecystitis. Moreover the cyst had ruptured into the right intrahepatic bile ducts. A sphincterotomy was performed with extraction of hydatid sand. A pericystectomy was necessary because of infectious deterioration of the patient. Albendazole was continued for 8 weeks after surgery. The second case presented with jaundice and weight-loss since 1 month. A large hydatid cyst caused compression on the bile duct bifurcation with proximal bile duct dilatation. A cystectomy was performed 2 weeks after albendazole therapy initiation, which was continued for 8 weeks after surgery. Follow-up of both surgical interventions was unremarkable. Although Echinococcus granulosus in not prevalent in Belgium, we must be aware of this pathology in patients coming from high endemic regions.

Endoscopic therapy in the management of hepatobiliary hydatid disease

Hydatid disease constitutes a serious public health problem throughout the world, especially in endemic areas, despite the use of various kinds of preventive measures. Currently, there are three treatment options for hepatic hydatid disease including surgery, PAIR (puncture, aspiration, injection, and re-aspiration), and chemotherapy with benzimidazole compounds. Each of these therapeutic modalities has limitations depending on the individual case. The authors review the use of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in the management of hepatobiliary hydatid disease (HHD) to clarify its place in the treatment algorithm among surgical, medical, and percutaneous measures. ERCP in the preoperative period: (1) defines the cystobiliary relationship to help in surgery planning, (2) permits evaluation for acute conditions like cholangitis and obstruction so that subsequent surgery can be performed on an elective basis, (3) may give permanent cure specifically in cases of frank intrabiliary rupture if evacuation of biliary tract and cystic cavity is manageable, and (4) when combined with preoperative endoscopic sphincterotomy may decrease the incidence of the development of postoperative external fistula. ERCP in the postoperative period: (1) can help to clarify the causes of ongoing or recurrent symptoms or laboratory abnormalities, (2) may help to resolve the obstruction or cholangitis due to residual material in biliary ducts, (3) may provide the chance to manage postoperative external biliary fistulae, and (4) may be a realistic solution for secondary biliary strictures. Considering the current literature and adding this experience, the authors propose a new treatment algorithm in HHD including medical, surgical, PAIR, and ERCP-related therapies. To illustrate the algorithm, a case is presented of a patient who had a persistent external biliary fistula in the postoperative period and was managed successfully by endoscopic approach.

Endoscopic sphincterotomy in the management of postoperative biliary fistula A complication of hepatic hydatid disease

BACKGROUND

Intrabiliary rupture is the most common complication of hepatic hydatid disease (HHD), and persistent biliary leakage is the most frequent complication after surgery for HHD. In this study, we evaluated the outcome of endoscopic sphincterotomy (ES) performed in the management of postoperative biliary fistula in 33 patients with HHD and investigated the effects of the daily output of the fistula and the timing of the ES on the duration of the fistula.

METHODS

Between January 1994 and April 2000, 33 patients (20 female, 13 male; median age, 44 years; range, 17-72) underwent ES at our clinics. The daily output of the biliary fistula ranged from 100 ml to 1000 ml (mean, 430 ml; in 18 patients < or = 400 ml; in 15 patients, >400 ml). The interval between the occurrence of the fistula and the performance of the ES ranged from 7 days to 5 months (median, 20 days; in 12 patients, < or = 2 weeks; in 21 patients >2 weeks).

RESULTS

In patients with fistula output 400 ml (n = 18) and >400 ml (n = 15), the average closure times for the fistula after ES were 10.7 +/- 4.5 and 10.4 +/- 4.9 days, respectively (t-test: p = 0.847, t = 0.195). In patients (n = 2) with a short interval between the occurrence of the fistula and ES (<2 weeks), the average closure time for the fistula was 11.6 +/- 5.6 days, whereas for the patients (n = 15) with longer intervals (>2 weeks) it was 9.4 +/- 3.9 days (t = test: p = 0.254, t = 1.180). The drainage from the fistula stopped after an average of 9.88 +/- 4.83 days in all patients who underwent ES, and there were no any complications. Pearson's correlation test (PC) showed no significant relationship between the time for the complete closure time of the fistula after ES and the fistula output (PC=-0.253, p=0.155) or for the duration of the fistula before endoscopic retrograde cholangio pancreatography (ERCP) (PC = -0.333, p = 0.058).

CONCLUSIONS

Endoscopic sphincterotomy is safe and effective and should be considered the minimally invasive procedure of choice for the management of postoperative biliary fistula due to HHD because it obviates the need for reoperation. If the sphincterotomy is successful, neither the daily output not the duration of the fistula has any influence on the time required for complete closure of the fistula.
