Intraoperative Plastibell Conversion to Open Sleeve or ZSR in Paediatric Circumcision: Two Cases
This paper reports two rare cases of successful intraoperative conversion from the Plastibell device to open sleeve or ZSR techniques in paediatric circumcision due to anatomical variations, demonstrating the safety and efficacy of such conversions within a high-volume Melbourne clinic.

Imagine the human body as a complex, bustling city where every part has a specific job and a precise size. Sometimes, to keep things running smoothly, surgeons need to perform minor "renovations" on this city. One of the most common renovations is a procedure called circumcision, which involves removing a specific layer of skin (the foreskin) to expose the tip of the penis (the glans). For decades, doctors have had a favorite tool for doing this in babies and young children: a clever little plastic ring called the Plastibell. Think of the Plastibell like a cookie cutter. You place the ring over the dough (the skin), pull the dough up through the hole, and the cutter does the rest, leaving a neat, uniform edge. It's fast, usually painless, and works like a charm for tiny infants because their parts are small and predictable. However, as children get older, their bodies grow, and just like a child outgrowing a favorite pair of shoes, their anatomy can change in ways that make a standard "cookie cutter" a bit tricky to use. This is where the story gets interesting: what happens when the tool doesn't fit the job perfectly in the middle of the operation?
This paper tells the story of two brave young patients who faced exactly that situation. The author, a doctor named Rahul Tipnis, shares a rare report from a busy clinic in Melbourne where two older boys (aged 10 and 11) came in for a circumcision using the Plastibell "cookie cutter." But once the surgery started, the doctors realized the plan needed a quick change. In the first case, the 11-year-old's "tip" was simply too big for the plastic ring; the ring wouldn't fit snugly, like trying to force a large head into a small hat. In the second case, the 10-year-old's skin was too tight to pull up over the ring without causing a mess, similar to trying to stretch a rubber band that's already at its limit. Instead of stopping the show or sending the boys to a hospital for a bigger operation, the doctors did something remarkable: they swapped tools right there in the room. They removed the plastic ring and immediately switched to a different method—one using a "sleeve" technique with stitches, and the other using a special stapler gun (called ZSR) that snaps the skin off in one clean motion.
The paper finds that these "mid-flight" changes were a total success. Both boys went home the same day, healed perfectly without any infections or bleeding, and ended up with great-looking results. The doctor notes that out of more than 800 procedures done in their clinic between 2020 and 2026, these were the only two times they had to switch from the plastic ring to something else. This suggests that while the Plastibell is still a fantastic choice for babies (whose parts are small and uniform), doctors need to be ready with a backup plan for older kids, whose bodies might be too big or too tight for the standard ring. The study confirms that even when the first tool fails, the surgery can be safely finished in the same session using local anesthesia (numbing just the area) rather than needing to wake the patient up with general anesthesia or move to a hospital. It's a reminder that in medicine, having a flexible toolkit is just as important as having a favorite one.
