Parietal complication of the hydatid disease: Comprehensive literature review

BACKGROUND

The aim of the study was to provide an overview of the medical literature on parietal complications of hydatid disease (HD).

METHODS

A literature search was conducted on PubMed, Medline, Google Scholar, and Google databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using keywords to identify articles related to parietal complications of HD in the thoracic and abdominal cavities. The following keywords were used: HD, hydatid cyst, cystic echinococcosis, alveolar echinococcosis, abdominal HD, thoracic HD, parietal complication, cutaneous fistulization, cystocutaneous fistulization, cutaneous involvement, external rupture, external fistulization, subcutaneous involvement, and subcutaneous abscess. The language of publication, journal, or country was not included as limitation criteria, and publications dated before August 1, 2016, were considered. Articles or abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management were included in the study, whereas articles with insufficient clinical and demographic data were excluded.

RESULTS

The literature review included 52 articles involving 55 patients with parietal complications of HD. Thirty-two articles were written in English, 15 in French, 2 in Spanish, 1 in Italian, 1 in German and 1 in Russian. All 55 patients (women, 30; men, 23; unknown, 2) involved in the study were aged 7 to 93 (mean ± standard deviation, 54.5 ± 20.2) years. A total of 24 patients had cysto-cutaneous fistula (Echinococcus granulosus), 12 had subcutaneous rupture, 10 had cutaneous fistula (E multilocularis), 3 had cystosubcutaneous abscess, 3 had cysto-cutaneo-bronchial fistula, 2 had cysto-cutaneo-bronchio-biliary fistula, and 1 had cutaneo-bronchial fistula. E granulosus were detected in 43 and E multilocularis in 12 patients through clinical, radiological, or histopathological examinations.

CONCLUSION

Parietal complications such as cysto-cutaneous fistulization are a rare complication of HD. Complicated HD should be considered in the differential diagnosis of patients presenting with cutaneous involvement, especially in HD endemic regions.

[The thoracic surgeon and the management of the bronchial biliary fistula of hydatid origin]

INTRODUCTION

The bronchial biliary fistula surgery is a major one, always going with a higher rate of complication especially in case of bile duct obstruction. The aim of this study is to find out the contribution of endoscopic sphincterotomy while reporting the results of surgical treatment of bronchial biliary fistulae by exclusive thoracotomy.

METHODS

This was a retrospective study, which took place in the Department of Thoracic Surgery, University Hospital Hassan II, from January 2009 to March 2016. The parameters studied in connection with the bronchial biliary fistula of hydatid origin were: age, sex, origin, history of surgery especially for hepatic hydatid cyst, term of bilyptysie, imaging results, preoperative cholangiography indications, surgical treatment modalities and patients trends.

RESULTS

A sample of 12 patients was included (6 men and 6 women) with an average age of 44 years old, with a gap spanning between 17 and 81 years. Seven patients had at least a history of hepatic hydatid surgery. The biliptysie was the main symptom in 8 patients. A biological cholestasis syndrome was found in 6 patients. The thoracoabdominal CT scan performed on all patients comes out with results in 100% of cases. Four patients received endoscopic retrograde cholangiography that allowed them to release the bile duct completely by sphincterotomy with extraction of hydatid membrane in one patient and with development of a biliary stent in another patient. The incision was a low posterolateral thoracotomy in 10 patients that went under surgery. It has allowed to deal in one-time liver and lung injuries combined with diaphragmatic breach repair. Inside the group of patients that went under surgery, the postoperative results were simple in 8 cases. We have noted an overall mortality rate of 18.2%.

CONCLUSION

Bronchial biliary fistula surgery complications remains considerable despite the progress of diagnostic imaging. Preoperative endoscopic sphincterotomy is a milestone in the handling of this surgery. It may even be suggested as exclusive therapy in inoperable patients with significant biliptisy.

Cutaneous fistulization of the hydatid disease: A PRISMA-compliant systematic review

AIM

To provide an overview of the medical literature on cutaneous fistulization in patients with hydatid disease (HD).

METHODS

According to PRISMA guidelines a literature search was made in PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to cutaneous fistulization of the HD. Keywords used were hydatid disease, hydatid cyst, cutaneous fistulization, cysto-cutaneous fistulization, external rupture, and external fistulization. The literature search included case reports, review articles, original articles, and meeting presentations published until July 2016 without restrictions on language, journal, or country. Articles and abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management, were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We also present a new case of cysto-cutaneous fistulization of a liver hydatid cyst.

RESULTS

The literature review included 38 articles (32 full text, 2 abstracts, and 4 unavailable) on cutaneous fistulization in patients with HD. Among the 38 articles included in the study, 22 were written in English, 13 in French, 1 in German, 1 in Italian, and 1 in Spanish. Forty patients (21 males and 19 females; mean age ± standard deviation, 54.0 ± 21.5 years; range, 7-93 years) were involved in the study. Twenty-four patients had cysto-cutaneous fistulization (Echinococcus granulosus); 10 had cutaneous fistulization (E multilocularis), 3 had cysto-cutaneo-bronchio-biliary fistulization, 2 had cysto-cutaneo-bronchial fistulization; and 1 had cutaneo-bronchial fistulization (E multilocularis). Twenty-nine patients were diagnosed with E granulosis and 11 had E multilocularis detected by clinical, radiological, and/or histopathological examinations.

CONCLUSION

Cutaneous fistulization is a rare complication of HD. Complicated HD should be considered in the differential diagnosis of cases presenting with cutaneous fistulization, particularly in regions where HD is endemic.

[Spontaneous cutaneous fistula of hydatid liver cysts]

BACKGROUND

Spontaneous cutaneous fistula of hydatid liver cysts is a rare complication. Its genesis involves anatomic factors as well as other local factors.

AIMS

An exhaustive literature review was conducted to identify the characteristics of this complication, treatment modalities and the results obtained.

PATIENTS AND METHODS

An exhaustive bibliographic search was made for all articles published in French and English relating to parietal complications of hydatid liver cyst, from which we retained only those involving cases of cutaneous cyst fistulas (communicating rupture), to which we added our own case.

RESULTS

Seventeen cases of cystocutaneous fistula have been reported. The reason for consultation was productive cutaneous fistula. Morphological investigations were highly evocative of the diagnosis. Thirteen patients were treated by surgery, two underwent percutaneous debridement, and two declined treatment.

DISCUSSION

Cutaneous fistula constitutes a rare mode of discovery of hydatid cyst. Fistulography and CT scan are extremely useful for diagnosis. Percutaneous debridement of the hydatid cyst represents a debatable alternative to surgical therapy.

Cutaneous fistula of liver echinococcal cyst previously misdiagnosed as fistulizated rib osteomyelitis

External fistulization or subcutaneous rupture of liver echinococcal cyst (EC) is found occasionally with total of 15 cases reported in the literature. We report a case of 60-year-old female previously misdiagnosed as fistulizated osteomyelitis of the 11^th rib. At computed tomography scan, non-vital EC was noted in the third liver segment. Under suspicion of external fistulization of perforated EC the patient underwent one-stage operation-pericystectomy and complete fistula excision. A retrospective analysis of the reported cases in the literature was performed with special references to classifying this rare entity. The main purpose of this report is to highlight the possibility of such a diagnosis when cutaneous fistula occurs in a same anatomic area with hydatid EC, even that cyst is proven to be calcified. We emphasize the role of a swift and radical surgical procedure including complete fistula excision to prevent secondary dissemination and post-operative complications.

[Parietal complications of hydatid cyst of the liver. Report of two cases in Tunisia]

The aim of this study is to consider the parietal complications of the hydatid cyst of the liver: the subcutaneous rupture of the cyst and spontaneous cutaneous fistula of liver hydatid cyst. 1(st) case: A 24-year-old woman, who underwent surgery 10 years ago for hydatid cyst of the liver, was admitted for a right hypochondrium mass and a fistula draining clear liquid containing cystic elements. Computed tomography (CT) showed a large cystic lesion in the subcutaneous tissue communicating with another cystic mass in the liver. The diagnosis of a cyst-cutaneous fistula due to a peritoneal hydatid cyst was established. The patient underwent surgical treatment and recovered uneventfully. 2(nd) case: A 40-year-old woman presented with a mass in her right hypochondrium. The diagnosis of subcutaneous rupture of a hydatid cyst of liver was established by ultrasonography and CT-scan. The patient underwent surgical treatment and recovered uneventfully. Parietal complications of hydatid cyst of the liver are extremely rare, clinical presentation can be derailing. The diagnosis is usually established by ultrasonography and CT-scan.

Nous rapportons un cas de kyste hydatique du foie rompu dans la paroi et dans le muscle psoas. Le diagnostic a été établi sur les données de l′échographie et surtout de la tomodensitométrie. Le patient a été opéré avec des suites simples.

Hydatid disease presenting as cutaneous fistula: review of a rare clinical presentation

Hydatid disease has a worldwide distribution as a result of more global travel. Liver and lungs are the most common sites for the primary hydatid cysts in the human body. We managed a 68-year-old man who presented with abdominal distension and umbilical fistula, discharging daughter cysts. Ultrasound imaging of the abdomen showed hepatic hydatid cyst forming a fistula at the umbilicus. The patient underwent a laparotomy with partial cystectomy and excision of the fistula tract. The umbilicus healed after the procedure. The patient did not have any recurrences in 5 years of follow-up. Spontaneous cutaneous fistulization of liver hydatid cyst is a rare presentation. A detailed literature search revealed 15 cases published in all languages. Hydatid disease presenting as an umbilical fistula has not been reported yet. We summarize all these cases including the presentation, findings, management, and outcome. Combined surgical and medical treatment is successful in healing of hepatic hydatid cutaneous fistula.
