Background X-ray cholangiography is of great value in the imaging of biliary tract diseases; however, occupational radiation exposure is unavoidable. Moreover, clinicians must manually inject the contrast dye, which may result in a relatively high incidence of adverse reactions due to unstable injection pressure. Thus, there is a need to develop a novel remote-controlled cholangiography injection device. Methods Patients with external biliary drainage requiring cholangiography were included. A remote-controlled injection device was developed with three major components: an injection pump, a pressure sensor, and a wireless remote-control panel. Image quality, adverse reactions, and radiation dose were evaluated. Results Different kinds of X-ray cholangiography were successfully and smoothly performed using this remote-controlled injection device in all patients. The incidence of adverse reactions in the device group was significantly lower than that in the manual group (4.17% vs. 13.9%, P = 0.001), and increasing the injection pressure increased the incidence of adverse reactions. In addition, the device helped operators avoid ionizing radiation completely. Conclusions With good control of injection pressure (within 10 kPa), the remote-controlled cholangiography injection device could replace the need for the doctor to inject contrast agent with good security and effectivity. It is expected to be submitted for clinical application.

Background and aim and objectives T-tube choledochostomy is performed following open or laparoscopic common bile duct exploration. There is increased concern regarding safety and efficiency of choledochostomy. The present paper evaluates the short-lived effectiveness and safety of T-tube bile leak after its removal. Patients and methods A total of 86 cases of choledocholithiasis were admitted to Al-Azhar University Hospital, Assiut. They underwent cholecystectomy (open), choledochotomy, and T-tube choledochostomy. T-tube choledochography was performed 10 days after surgery, and removal of the tube was done after 12 days. Results Morbidities, mainly bile leak and peritonitis, were estimated. A total of 10 patients had evidence of radiological leak. Marked biliary reactions were noticed in six cases promptly following T-tube removal. Five of these cases had clinical peritonitis, treated conservatively. Only one patient had biliary peritonitis and required reoperation. Conclusion The operative use of T-tube choledochostomy has been in dramatical decline in the past 20 years (owing to the development and adoption of removal lesser invasive maneuvers of choledocholithiasis removal). Manipulation of T-tube (situation and extraction) is technically exigent. Intricacy and morbidity are critical; thus, it is recommended not to be performed as a routine maneuver. Easier options must be taken into account initially.
