Clinical study of a novel circumcision with minimal invasion for phimosis
Conventional circumcision remains a traditional and the most common surgical option for phimosis and paraphimosis. There has not been a breakthrough in technology so far. In this report. we presented a novel operative technique, invented by Dr. Shang to remove the prepuce with minima invasion, and reported a study from 52 patients diagnosed of phimosis or paraphimosis and treated with this technique, from October 2003 to February 2005 in the 2nd Affiliated Hospital of Wannan Medical College.
MATERIALS AND METHODS:
Fifty-two patients with phimosis or paraphimosis were included, 40 of them were married and 12 were unmarried, from the age of 17 years to 56 years with a mean age of 38 years. The length of resting penises ranged from 2.5 to 10 cm.
Material: the unique tool, called Noninvasive Operation Loops (patent number, 2003.ZL02237969.X), used for the operation, was invented by Dr. Jianzhong Shang, a special scientist of Chinese National Management Institute. These noninvasive operation loops cast in polypropylene engineering plastic consisting of an inner loop and an outer loop. These two loops can be held together through compression by screws. These noninvasive operation loops are composed of various sizes. packaged in sterile and disposable. (See figures in Figure1 (Legend: Inner loop, Outer loop, Combined loops).
Surgical Procedure: sterilize. unfold surgical towel, and expose the penis; block venous blood return with rubber cuff placed at the root of penis, extract venous blood from extended veins by a needle puncture, and slowly inject 2 ml of 2% lidocaine, wait for 5 minutes until anesthesia is completed and satisfactory; select a proper size of operation loop, first put the inner loop around penis, turn the foreskin outwardly to cap the inner loop, fully expose the glans, for phimosis, cut open the foreskin ventrally, place the inner loop 0.5 cm above the corona, and around 1.0 cm above penile ligament, cap the outer loop, and tie up screws. excise the extra foreskin along the outer loop. Expose the glans while covering wounds with sterile gauzes, and release cuff. Six days after surgery, remove loops, and the wound would fully heal within 15-20 days. (Figure 2: Prior surgery, operation completion, and after surgery)
After the operation, 50 out of 52 patients had primary wound healing. The remaining two individuals showed delayed wound healing secondary to wound infection caused by premature sexual intercourse in the ignorance of medical instructions. There was no scaring and no sequelae.
Phimosis is a condition in which the foreskin cannot be retracted behind the glans penis. It may produce urinary obstruction with ballooning the foreskin and may lead to penile undergrowth and maidevelopment? in boys, recurrent meatitis and balanitis (i.e.. inflammation of the glans), and even penile carcinoma. It might affect patients’ sex life. Phimosis is not uncommon. Our new approach is indicated to patients with phimosis and paraphimosis. Conventional circumcision has traditionally been regarded as the treatment of choice for phimosis and paraphimosis. It requires multiple procedures such as incise. stanch, and suture. It is going to have a scar after healing. The laser operation procedure has its own disadvantages such as a thermal burn.
Our approach offers a breakthrough from traditional modes of thinking. The procedures in this revolutionary approach no longer require incision and suture. By compression of the operation loops, consequently, the distal part of the foreskin becomes ischemic, necrotic, and thus shed. The surgical procedures only take 2-5 minutes to complete. The operation loops are usually removed in 6 days after surgery. The wound heals in 15-20 days without scarring. No complex surgical tools are needed. Miscellaneous procedures such as stanching are avoided, therefore, the incidence of postoperative infection and other complications is significantly low. It is not necessary to take any medications such as estrogen or to limit daily activities such as taking a shower. It does not affect urination and has no complications.
Comparison between our novel approach and traditional circumcision:
Novel Circumcision Traditional Circumcision
near noninvasive, simple, less painful, and no
invasive, complex, more painful, and scarring
usually only one surgeon
at least two surgeons
no conventional surgical tools required
both conventional surgical tools and an operation room required
no bleeding, no stanching
less than 5 minutes
more than 30 minutes
Because of the removal of the un-retractable foreskin, in a portion of our 52 patients with phimosis, the postoperative penis becomes longer and sturdy and improves its sexual function in variable degrees.
Our new method of circumcision with minimal invasion is superior to the traditional one with convincing curative effects. It deserves as a treatment of choice or at least as a viable alternative for phimosis.
