Background: This study aimed to demonstrate the effectiveness of a percutaneous method for treating intra-abdominal abscesses caused by gastrointestinal anastomotic leakage using tandem catheter placement for simultaneous drainage. Methods: This retrospective study involved 12 patients with intra-abdominal abscesses from anastomotic leakage who underwent image-guided percutaneous drainage. In the tandem drainage technique, one or more catheters were inserted into the abscess while an additional catheter was advanced into the gastrointestinal tract through the anastomotic dehiscence to decompress the tract and prevent further leakage. The study evaluated the technical and clinical success rates of this approach. Results: Technical success was achieved in nine of 12 patients (75.0%), with clinical success in eight of these nine patients (88.9%). The mean overall drainage duration after tandem placement was 65.0 days (range, 6–154 days), and the mean hospitalization duration for patients with clinical success was 66.7 days (range, 10–156 days). Conclusion Simultaneous tandem drainage is a feasible treatment for intra-abdominal abscesses caused by anastomotic leakage and may be a viable option for patients who are not candidates for surgery.

This study aimed to clarify the relative growth in thigh muscle size and sprint performance in children from 3 to 15 years. A total of 902 children performed a 30-m sprint test. Sprint time was measured by a photocell system. Muscle thicknesses of thigh anterior and posterior were determined by using a B-mode ultrasound. For 431 children, step frequency (SF) and step length (SL) during the sprint running were also analyzed with the films, and corrected by leg length. Using an allometry equation based on body height, relative growth of thigh muscle size and sprint performance was estimated. In both boys and girls, there was a breakpoint (BP) at which the rate of development in sprint velocity changes, and the rate of development was slower after the BP. On the other hand, the rate of growth in thigh muscle size after the BP was superior to that before the point, except of thigh posterior in boys. Regardless of sex, the rate of development in SL index after the BP became to be lower with increasing body height, whereas SF index relatively increased. These current findings indicate that in boys and girls, the rate of development in sprint velocity becomes to be lower above a certain body height, and the relative slow development may result from those in SF and SL.
