ZSR Stapler Circumcision
Circumcision ranks among the most frequently conducted surgical operations worldwide, tracing its origins back several millennia. The procedure entails surgically excising the foreskin—the retractable layer of skin that encloses the glans penis—to completely reveal the penile head. Generally, it is a brief outpatient surgery, commonly executed with local anesthesia in infants, while older children may receive supplementary sedation based on clinical circumstances and individual requirements.
What is ZSR Stapler circumcision?
The ZSR stapler, also referred to as the circumcision anastomat, represents an innovative advancement in circumcision technology. This specialized device combines a circular surgical blade with an integrated stapler, allowing it to simultaneously excise the foreskin and secure the incision with a precise row of staples near the cutting line.
Unlike traditional methods that rely on separate cutting and suturing steps, the ZSR streamlines the process into a single, efficient action. In Singapore, it is currently the only such device approved by the Health Sciences Authority (HSA), and it is uniquely available in a comprehensive range of sizes to accommodate both adult and pediatric patients.
The ZSR circumcision anastomat offers significant advantages, including enhanced procedural efficiency, reduced operating time, and accelerated patient recovery. By integrating cutting and skin closure, the device minimizes blood loss and lowers the risk of complications, making it a preferred choice for modern circumcision.
Brief History of Circumcision Techniques
Circumcision began around 2400 BCE in ancient Egypt and among Hebrews (circa 1200 BCE) as a ritual, using flint or bronze tools to cut the foreskin freehand, with minimal bleeding control. Through the Middle Ages, Jewish and Islamic communities continued with knives or scissors, aided by cauterization or herbs. The 19th century medicalized the practice in the West, introducing anesthesia and tools like the Gomco clamp to reduce bleeding. The 20th century refined techniques with the Plastibell and Mogen clamp, standardizing neonatal circumcision.
Modern innovations emerged later: Laser circumcision uses a laser to cut and cauterize, offering precision, less bleeding, and quick recovery, though it’s costly. The Shang Ring, a disposable ring device, excises the foreskin and necroses tissue over 7–10 days, popularized for HIV prevention with minimal complications. Stapler circumcision, like the ZSR, cuts, and staples simultaneously, ensuring fast procedures, reduced trauma, and recovery in 2–3 weeks. These advancements reflect a shift from ritual to medical efficiency, adapting to safety, speed, and patient outcomes across cultures and eras.
Who Gets ZSR Stapler Circumcision?
The ZSR stapler circumcision is a modern, efficient procedure performed under local anesthesia, making it a comfortable outpatient option for a wide range of individuals. People choose this method for various personal, medical, or cultural reasons, tailored to their unique needs. Here’s who might opt for it and why:
- Medical Reasons: This procedure is often recommended to address specific health conditions. For example, phimosis, where the foreskin is too tight to retract, can cause pain, hygiene issues, or infections, and circumcision offers a permanent solution. Similarly, men with recurrent balanitis (inflammation of the glans) or urinary tract infections linked to foreskin issues may benefit. The ZSR’s quick, precise approach minimizes recovery time, making it ideal for those seeking relief from these medical challenges.
- Aesthetic Appearance: Some individuals pursue circumcision to enhance their satisfaction with their physical appearance. Whether it’s a preference for a cleaner look or a desire to align with a specific ideal, the ZSR stapler ensures a neat, consistent result.
- Cultural or Religious Reasons: Circumcision holds deep significance in many traditions and faiths, such as Judaism and Islam, where it’s often a rite of passage or a symbol of identity. The ZSR method respects these practices by offering a safe, streamlined alternative to traditional techniques, performed in a clinical setting under local anesthesia. It’s suitable for all ages, from infants to adults, aligning with cultural or religious timelines.
- Psychological Factors: For some, circumcision can boost confidence or ease discomfort tied to self-image. Men who feel self-conscious about their foreskin—due to hygiene concerns, partner feedback, or personal unease—may find this procedure liberating. The ZSR’s efficiency and minimal downtime help address these psychological drivers, supporting emotional well-being alongside physical change.


How is ZSR Stapler Circumcision Performed?

Consultation
Your experience starts with a thorough consultation with our doctor. We’ll discuss your reasons for choosing circumcision – whether medical, cultural, or personal—and evaluate your health to ensure the procedure is suitable. This includes checking for any contraindications to the procedure. During the exam, we’ll take precise measurements to select the ideal ZSR device size. This step is crucial for minimizing discomfort, reducing the risk of complications, and ensuring a smooth recovery tailored to your needs.
Before the Procedure
Your comfort is our priority. We begin by applying a numbing cream to the foreskin, allowing it to take effect before gently removing it. Next, a local anesthetic is administered via a small injection to fully desensitize the area. This dual approach ensures you feel little to no discomfort during the procedure. You’ll stay awake and relaxed throughout the entire process, which typically lasts just 10–15 minutes. Our team will guide you at every step, keeping you informed and at ease.
During the Procedure
Once the anesthesia is fully effective, the circumcision begins. Here’s how the ZSR stapler works:
- Preparation: The foreskin is carefully retracted to expose the glans (the head of the penis).
- Protection: A safety rod is placed over the glans to shield it during the procedure.
- Positioning: The foreskin is repositioned over the safety rod and secured in place.
- Stapler Alignment: The ZSR stapler is positioned over the safety rod, and its alignment is double-checked for precision.
- Cutting and Stapling: When activated, the stapler simultaneously cuts the foreskin and applies a circular row of staples to seal the edges, eliminating the need for traditional sutures.
- Healing Support: A silicone ring is attached to the stapled area, ensuring hemostasis (bleeding control) and aiding natural healing. This ring detaches on its own after about two weeks. The process is quick, efficient, and designed to minimize tissue trauma, ensuring a clean and consistent result.
After the Procedure
Once completed, our doctor removes the safety rod and ZSR stapler, leaving the stapled area intact with its silicone ring. A protective bandage is applied to keep the site clean and secure. You’ll receive clear aftercare instructions, including how to manage the bandage and what to expect as the staples and ring naturally fall off over the next two weeks. Most patients can leave the clinic shortly after 10-15 minutes of monitoring, resuming light activities within a day or two, with full recovery typically achieved in 4-6 weeks. Our team remains available to address any questions or concerns during your healing process.

What is the Follow-Up after ZSR Stapler Circumcision?
Patients are asked to return to the clinic on day 3 for bandage removal. If no bleeding is observed, they may go home and resume bathing as normal. However, if bleeding persists, a fresh dressing is applied, which the patient can remove at home on day 7. A follow-up visit is scheduled at one month to confirm proper wound healing and verify that the silicone ring has naturally detached.
What is the Recovery like after ZSR Stapler Circumcision?
Patients can resume daily activities on the same day with minor restrictions to promote optimal healing. They should avoid showering initially to keep the dressing clean and dry, preventing it from becoming soaked or soiled. If the dressing detaches before the review on day 3, patients must return to the clinic for reapplication. Normal showering can resume after the bandage is removed on day 3. Post-shower and after urination, the wound should be kept dry to reduce infection risk. Strenuous activities and exercise should be avoided for 4–6 weeks, as should sexual intercourse, to ensure complete recovery.

What are some of the complications of ZSR Stapler Circumcision?
The ZSR stapler circumcision technique is generally considered safe, with complication rates lower than traditional circumcision in many studies. The frequency varies by patient factors, technique precision, and aftercare compliance. Below is a breakdown of the various possible complications.
Likely/Often Happen
These complications are more commonly reported but are typically mild and manageable:
- Pain or Discomfort: Mild to moderate pain at the staple site is frequent during the first few days post-procedure, often resolving with over-the-counter pain relief.
- Swelling: Temporary swelling around the circumcision site occurs in many patients, peaking around day 3–5 and subsiding within a week as healing progresses.
- Minor Bleeding: Small amounts of bleeding or spotting at the staple line are common. If this occurs apply gentle pressure with a clean gauze and it’ll stop on its own.
- Delayed Ring/Staple Detachment: The silicone ring or staples may take longer than the expected 14 days to fall off, causing minor irritation but no serious harm.
Rarely Happen
These complications are infrequent, occurring in less than 5% of cases, and may require medical attention:
- Infection: Redness, pus, or a fever could mean an infection, a very uncommon complication. You want to keep the area clean and dry to minimize the risk of infection. If you notice these signs please call our clinic for a review.
- Excessive Bleeding: Heavy bleeding that doesn’t stop with pressure is rare. If this happens, please inform our clinic right away for further monitoring and care.
- Staple Retention: In rare instances (<2%), staples don’t detach and require manual removal by a doctor, causing discomfort or delayed healing.
- Wound Dehiscence: Partial separation of the stapled edges is very rare, possibly due to tension or trauma, and may need minor surgical repair.

How do different techniques compare with ZSR Stapler Circumcision?
Choosing a circumcision method can feel overwhelming. Whether for medical, personal, or cultural reasons, options like conventional circumcision, laser circumcision, Shang Ring circumcision, and ZSR stapler circumcision each have distinct pros and cons.
Conventional circumcision is widely available and performed by most surgeons, primarily because it requires no specialized equipment. However, it tends to be a longer procedure, typically lasting between 30 and 60 minutes. Patients undergoing conventional circumcision have a higher risk of bleeding, require sutures, and generally experience more postoperative pain and swelling. Healing is relatively slow, usually taking about 4 to 6 weeks.
Laser circumcision offers precise cutting with minimal tissue damage, simultaneously cauterizing tissue to significantly reduce bleeding. Patients typically experience less postoperative pain and swelling, resulting in faster healing, usually within 2 to 3 weeks. Despite these advantages, laser circumcision still requires sutures and carries a risk of burns if the equipment is mishandled. Additionally, the procedure can be relatively lengthy, lasting around 20 to 40 minutes.
The Shang Ring circumcision technique stands out due to its speed, typically completed in just 10 to 15 minutes, and its simple, suture-free ring design. This method notably reduces the risk of bleeding and infection. However, the ring remains in place for approximately 7 to 10 days, potentially causing discomfort. Rarely, the Shang Ring may slip or cause tissue necrosis, although such complications are uncommon.
Stapler circumcision is another quick method, typically taking about 10 to 15 minutes. It simultaneously cuts and staples the foreskin, minimizing bleeding and eliminating the need for sutures. The staples and ring naturally detach after 10 to 14 days. This technique leads to reduced pain and rapid recovery within approximately 2 to 3 weeks, with consistent and aesthetically pleasing results. However, stapler circumcision has some limitations, such as size restrictions that make it less suitable for very young infants. Additionally, some patients may experience mild irritation due to the staples.
