[Surgical treatment of hydatid cysts with large biliocystic fistula in conservative strategy]. / Prise en charge des larges fistules bilio-kystiques lors de la chirurgie conservatrice du kyste hydatique du foie.

INTRODUCTION: the treatment of large biliocystic fistulas is not unanimous among authors in the absence of consensus or a high level of evidence. There is a controversy over the use of a radical approach which allows the fistula to be sutured in a healthy area or conservative treatment that poses repair issues. The purpose of this study is to compare different conservative techniques to treat large biliocystic fistulas. METHODS: we conducted a retrospective study of 54 patients with large fistulas in the Department of General Surgery at the Habib Bourguiba University Hospital in Sfax over a period of 9 years (2010 - 2018). RESULTS: fourty-four patients were enrolled in the study. Abdominal ultrasound suggested opening of the bile ducts in 18 cases (47.4%) while computed tomography (CT) scan suggested opening in 28 patients (68.3%). The treatment of fistulas was based on DITFO (internal trans-fistulary drainage) in 18 cases (33.3%), cystobiliary disconnection (PERDROMO) in 11 cases (20.4%) and bipolar drainage in 25 cases. Specific surgical morbidity rate was 31.5% and it was dominated by postoperative biliary fistula in 18.5% of cases. DITFO technique was associated with shorter hospital stay (p=0.028) and lower morbidity rates (22.2%) with no statistically significant difference. CONCLUSION: DITFO technique is the gold standard technique in the treatment of biliocystic fistula because it is associated with lower morbidity rates and the shortest hospital stay.

Nodular Hepatic Tuberculosis Masquerading as a Seminoma Liver Metastasis.

Isolated macro-nodular liver tuberculosis is a very rare condition. It may mimic primitive or secondary tumors of the liver. This could delay or mislead the therapeutic management. An immunocompetent 48-year-old man with a history of non-metastatic seminoma was treated with right orchidectomy followed by 20 Gy radiotherapy. The discovery, 8 months later, of a 2 cm nodule of the hepatic dome evoked a liver metastasis. Percutaneous biopsy was not feasible. Wedge resection was performed whereas medical treatment would have sufficed, as pathologic examination of the resected specimen showed a macro-nodular hepatic tuberculosis. The patient received anti-tuberculosis drugs for 9 months. The diagnosis of isolated macro-nodular liver tuberculosis is frequently misleading, particularly in immunocompetent and paucisymptomatic patients. Thus percutaneous biopsy is mandatory for diagnosis and also prior to any major surgeries.
