AbstractTherapy choices for cystic echinococcisis (CE) are stage-specific: surgical, minimally invasive, medical or observation without intervention. PAIR (percutaneous aspiration, instillation of a scolicide, and re-aspiration) has been considered the treatment of choice for uncomplicated echinococcal liver cysts. However, PAIR carries the risk of toxic cholangitis or hypernatremia and that the cyst frequently refills with bile after withdrawing the catheter. We treated a patient with a giant CE 1 liver cyst with puncture drainage (PD) under albendazole coverage. Drainage enabled us to monitor the morphology of protoscolices under praziquantel (PZQ) co-medication. Protoscolices degenerated within 5 days of PZQ 50 mg/kg/d. The cyst cavity solidified with no evidence of reactivation or secondary spread. Percutaneous treatments can replace surgery in a significant number or cases with hepatic CE. PD allows to assess microscopically the viability of protoscolices under co-medication with PZQ–albendazole and to avoid the instillation of topical scolicides.

The World

Hydatid cyst is still endemic in various regions of the world. It is the most frequent cause of liver cysts worldwide. Urticaria is sometimes the first manifestation of the disease. However anaphylactic reaction and urticaria have been very rarely reported in the literature. Traditionally, surgery has been the only accepted mode of treatment; however, percutaneous treatment has recently been proposed as an alternative. Cases of anaphylaxis have been reported after percutaneous drainage of hydatid cyst. However, anaphylaxis usually develops within a few hours. Herein, we describe the case of a patient who presented with hydatid cyst causing chronic urticaria and late anaphylactic reaction following percutaneous aspiration of a liver hydatid cyst. We emphasize that physicians should be aware of hydatid cyst as a possible etiology for seemingly chronic spontaneous urticaria, especially in endemic regions. Patients should be kept under observation for at least one day due to the risk of early and late anaphylaxis after percutaneous aspiration treatment.

AbstractIn vivo bioprinting has recently emerged as a direct fabrication technique to create artificial tissues and medical devices on target sites within the body, enabling advanced clinical strategies. However, existing in vivo bioprinting methods are often limited to applications near the skin or require open surgery for printing on internal organs. Here, we report a ferromagnetic soft catheter robot (FSCR) system capable of in situ computer-controlled bioprinting in a minimally invasive manner based on magnetic actuation. The FSCR is designed by dispersing ferromagnetic particles in a fiber-reinforced polymer matrix. This design results in stable ink extrusion and allows for printing various materials with different rheological properties and functionalities. A superimposed magnetic field drives the FSCR to achieve digitally controlled printing with high accuracy. We demonstrate printing multiple patterns on planar surfaces, and considering the non-planar surface of natural organs, we then develop an in situ printing strategy for curved surfaces and demonstrate minimally invasive in vivo bioprinting of hydrogels in a rat model. Our catheter robot will permit intelligent and minimally invasive bio-fabrication.
