Echinococcal disease can present with giant abdominal cysts at very young age: A case report.

Echinococcus granulosus larvae can cause cystic echinococcosis (CE, also known as hydatid disease) in humans. The latent phase of hydatid disease lasts for years as a result of the slow growth of the cysts, which only become symptomatic when they are large. Therefore, CE is seldomly seen in very young children. Here we present a 4-year-old boy with two giant asymptomatic abdominal cysts. Ultrasound was inconclusive in regard to the nature of the cysts and serology for echinococcosis was negative, rendering CE improbable also in view of the young age. Nevertheless, in the absence of other conclusive explanations, the patient was started on albendazole. A subsequent diagnostic percutaneous puncture with direct microscopy of cyst fluid revealed parasitological evidence of echinococcosis. This case report shows that CE can present with giant cysts also at very young age and should be considered as a possible diagnosis in all children with giant abdominal cysts.

Biliopancreatic and biliary leak after pancreatoduodenectomy treated by percutaneous transhepatic biliary drainage.

BACKGROUND: Complementary to percutaneous intra-abdominal drainage, percutaneous transhepatic biliary drainage (PTBD) might ameliorate healing of pancreatic fistula and biliary leakage after pancreatoduodenectomy by diversion of bile from the site of leakage. This study evaluated technical and clinical outcomes of PTBD for this indication. METHODS: All patients undergoing PTBD for leakage after pancreatoduodenectomy were retrospectively evaluated in two tertiary pancreatic centers (2014-2019). Technical success was defined as external biliary drainage. Clinical success was defined as discharge with a resolved leak, without additional surgical interventions for anastomotic leakage other than percutaneous intra-abdominal drainage. RESULTS: Following 822 pancreatoduodenectomies, 65 patients (8%) underwent PTBD. Indications were leakage of the pancreaticojejunostomy (n = 25; 38%), hepaticojejunostomy (n = 15; 23%) and of both (n = 25; 38%). PTBD was technically successful in 64 patients (98%) with drain revision in 40 patients (63%). Clinical success occurred in 60 patients (94%). Leakage resolved after median 33 days (IQR 21-60). PTBD related complications occurred in 23 patients (35%), including cholangitis (n = 14; 21%), hemobilia (n = 7; 11%) and PTBD related bleeding requiring re-intervention (n = 4; 6%). In hospital mortality was 3% (n = 2). CONCLUSION: Although drain revisions and complications are common, PTBD is highly feasible and appears to be effective in the treatment of biliopancreatic leakage after pancreatoduodenectomy.

Imaging in encapsulating peritoneal sclerosis.

Encapsulating peritoneal sclerosis (EPS) is a rare but very severe complication of long-term peritoneal dialysis (PD). Since the first reports on this disease in the eighties, several imaging techniques have been used for its diagnosis. Because of the rarity of this condition, uniformity in modality and protocols for abdominal imaging for diagnosis has been lacking overtime. Nowadays, computed tomography (CT) is most often used. In this review, we provide an overview of all imaging modalities that have been used overtime to diagnose EPS as a late complication of PD. Imaging features characteristic for EPS and advantages as well as shortcomings of all modalities are discussed. We believe that when EPS is suspected, CT with contrast enhancement should be the modality of first choice in clinical practice.
