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

Hospital-based retrospective analysis of 224 surgical cases of lung hydatid cyst from southern Iran

BACKGROUND

The lungs are considered the second-most frequent location for hydatid cyst in human. The current retrospective hospital-based study aimed to assess the epidemiological data, clinical presentation, and treatment outcomes of lung hydatid cyst in patients who underwent surgery for this disease in Fars province, southern Iran.

METHODS

In this retrospective study, hospital records of 224 pulmonary hydatid cyst patients were assessed in two main university-affiliated hospitals in Fars Province, southern Iran. Clinical features of patients, epidemiological data, cyst features, surgical interventions, and treatment outcomes were reviewed and analyzed.

RESULTS

A total of 224 hydatid cyst cases of the lung were reviewed. Male patients accounted for the majority of cases (60.4%). The average age of the patients was 31.13 (± 19.6), ranging from 2 to 94 years old. Of the 224 patients, 145 (75.9%) cases had only one single cyst and mostly 110 (53.9%) located in the right lung. Also, 6 (2.9%) cases had cysts in both lungs. The lower lobe of the lungs was the most common location of the hydatid cyst. The average size of lung hydatid cyst was 7.37 cm (SD = 3.86; rang: 2-24) while for the cyst areas was 42.87cm² (SD = 52.76; range: 2-488). Regarding the surgical method, 86 (38.6%) cases were operated by lung resection surgery while 137 (61.4%) cases had lung preserving one. The chief complaints of the patients were cough (55.4%) and dyspnea (32.6%). Relapse was documented in 25 (11.16%) of cases.

CONCLUSIONS

Lung hydatid cyst is a common infection in southern Iran. Lung preserving surgery is the method of choice for the management of hydatid cyst. Relapse, which was not uncommon in our study, is a challenging feature of hydatid cyst management.

Cutaneous fistulization: An extremely rare presentation of hydatid liver cyst in a child

We report the case of a 10-year-old child who presented with a renitent lesion on the left abdominal wall. Clinical, radiological, and intraoperative findings concluded to a cutaneous fistulization of a hydatid cyst of the left lobe of the liver. The diagnosis was confirmed by histopathological examination. The child was successfully treated with acombination of medical and surgical management. Complicated hydatid disease should be considered in the differential diagnoses of patients presenting with cutaneous fistulization, particularly in regions where hydatid disease is endemic.

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.

Hepatic hydatid cyst presenting as a cutaneous fistula

Hepatic hydatid cysts are usually asymptomatic. Nevertheless, they may rupture, causing anaphylactic shock or fistulation. Cutaneous fistulae caused by ruptured hepatic hydatid cysts are extremely rare. Herein, we report a case of infected cutaneous fistula caused by a ruptured hepatic hydatid cyst. A 57-year-old man presented to Al-Ain Hospital complaining of swelling in his right upper quadrant (RUQ) of 5 months' duration. The abdomen was soft, having a fluctuant tender swelling of 12 cm × 15 cm in the RUQ associated with a pus discharging fistula. The patient was admitted with a provisional diagnosis of abdominal wall abscess with pending sepsis. Surgical incision and drainage were performed under general anesthesia. Initially, around 15 ml of pus was drained, followed by the removal of multiple sized transparent cysts typical of hydatid disease. Postoperative abdominal computed tomography (CT) scan showed multiloculated hepatic cysts in the sixth, seventh, and left lobes with the involvement of the abdominal wall. The patient was treated with oral albendazole 400 mg twice daily for 30 days. Repeated CT scan at 4-month follow-up showed a significant reduction of size of the cysts, indicating proper response to treatment. A cutaneous fistula as a complication of a ruptured hepatic hydatid cyst is extremely rare. Awareness of this complication, especially in endemic areas, and using proper imaging and serological tests are vital for reaching a proper diagnosis.

Superinfection of a Dead Hepatic Echinococcal Cyst with a Cutaneous Fistulization

Cystic echinococcosis (CE), also known as "hydatid disease" (HD), is a zoonotic infection caused by the larval stage of Echinococcus granulosus, which infects humans as intermediate hosts through the orofecal route. Carried by the intestinal venous blood, the embryos released by the eggs of the tapeworms can reach every organ, especially the liver, turning into a hydatid cyst. Usually asymptomatic, the cysts can be incidentally detected through radiological examinations performed for other reasons. We show an unusual case of superinfection of a hydatid cyst with typical radiological features of inactivity (WHO-type CE5) with an even rarer skin fistulization passing through a subcutaneous-abdominal abscess involving the right iliac muscle.
