ASCOVIME (Association des Competences pour une Vie Meilleure) is a non-profit Cameroonian humanitarian association. Founded in 2008 by Dr. BWELLE Georges, a visceral surgeon working in the general surgery department at Yaounde Central Hospital. The association organizes various medical missions throughout the country and throughout the year in remote villages to carry out health and education campaigns. These include medical consultations, the administration of medical care and treatment, surgical operations, awareness-raising campaigns on major endemics (malaria, Sexually Transmissible Infections and AIDS, diarrhea, malnutrition, etc.) and hygiene, which are carried out free of charge every week.

An ASCOVIME team, made up of dozens of medical and civilian volunteers, goes out to meet villagers confined to the four corners of Cameroon. Villages are selected on the basis of the absence of health facilities within a 20km radius, the poverty status of the local population, their willingness to accept the project, and the approval of the administrative and local authorities.

In 2011, the association treated over 10,000 people free of charge. Over 500 people underwent surgery, more than 700 optical lenses were supplied, and hundreds of books, notebooks, pens, toiletries were donated to children in numerous schools throughout the country. All thanks to individual donations. In 2013, 28 campaigns were carried out in the field, resulting in 10,271 medical consultations, 656 surgical procedures, 1040 dental consultations, 1959 ophthalmological consultations, the distribution of 982 pairs of lenses and school supplies to more than 4045 pupils. Most of the active members are Cameroonian: doctors, surgeons, students, ophthalmologists and volunteers. International volunteers are also present. They contribute their expertise and energy to the synergic development of the association.

The ASCOVIME-MBASSI Modified Sleeve resection technique has been practiced and taught since 2011 as part of health campaigns throughout most of Cameroon, as well as at the Yaounde Central Hospital. It was developed by Dr MBASSI Achille Aurèle, Urologist and specialist in urological reconstruction surgery at the Yaounde Central Hospital.

Preoperative evaluation: coagulation profile, full blood count are done prior to anesthetic consultation. Pre-anesthetic consultation was done for all the patients. The patient is placed in the supine position, cutaneous asepsis done using povidone iodine and sterile draping (Figure 1). In the case of loco-general anesthesia, the practitioner can generally perform a penile block, which involves infiltrating a local anesthetic at the base of the penis to block the dorsal nerves that ensure its sensitivity. The injection is made below the pubic symphysis, 0.5 to 1 cm on either side of the midline. Sedation may also be administered, depending on the patient's age and history. In this case of general anaesthesia, sedation is done.

The foreskin is freed and pulled over the glans penis to allow access to the area to be excised. If smegma is present, it is gently removed. The different stages of the operation are as follows

Step1:Detachmentoftheglanspenisandremovingpreputialadhesions(Figure 2)

Figure 2. Detachment of the preputial skin from the glans penis.

In this crucial first step of our circumcision technique, we begin by gently decapping the glans and separating any preputial adhesions. This step requires great precision to avoid any trauma or damage to the delicate tissue of the foreskin and glans penis. Detachment involves removing the foreskin. This step can be delicate, especially in infants where the foreskin is often tightly attached to the glans. We use gentle maneuvers to separate the foreskin from the glans without causing pain or damage.

We then proceed to separate the preputial adhesions. It is common for the foreskin to adhere to the glans in infants and young children. These adhesions must be carefully separated to allow complete unhooding and uncomplicated circumcision. We use gentle, repetitive movements to separate the adhesions, minimizing the risk of bleeding or trauma to the glans.

This first step is essential to set the stage for the actual circumcision procedure. By safely and precisely decapping and separating preputial adhesions, we ensure that the procedure runs smoothly and reduces the risk of post-operative complications.

Step2:Prepuceretractionandproximalhorizontalincision

In this stage of the technique, we retract the foreskin to approximately 1.61 cm above the balano preputial groove. This is crucial as it exposes enough tissue to safely make the first incision above the coronal furrow. Precise, controlled foreskin retraction is performed to avoid excessive trauma to the surrounding tissue. Once the foreskin has been retracted to the appropriate distance, we make the first incision. This incision is made with great precision to create a circumferential opening around the foreskin, just above the retracted edge. The incision is made with sharp, sterile surgical instruments (scalpel blades) to ensure a clean, precise surface cut (Figure 3).

Figure 3. Retraction of the prepuce and proximal horizontal incision.

By retracting the foreskin to the appropriate distance and making the first incision with precision, we ensure a smooth start to the circumcision procedure and ensure that the rest of the procedure can be carried out efficiently and safely.

Step3:Dilatationofthepreputialorificeandseconddistalhorizontalincision

In this next step of the circumcision procedure, we maintain dilatation of the preputial orifice, followed by a distal horizontal incision below the sulcus. This is a delicate step, as it widens the space between the foreskin and the glans, making it easier to detach rather than excise the foreskin. Dilatation of the preputial orifice is carefully maintained using two forceps in 11 o’clock and 1 o’clock positions. Remove any remaining adhesions. The purpose of this step is to enlarge the opening to allow adequate access to the preputial tissue for circumcision. Once the orifice has been appropriately dilated, we can proceed with the proximal horizontal incision. This second incision is made under the balano-preputial fold, horizontally to the axis of the penis, creating a circumferential opening around the prepuce at a specific distance from the first incision (Figure 4).

Figure 4. (a) Dilatation of the preputial orificeat 11’o clock and 1 o’clock; (b) Distal horizontal incision. The incision excises part of the foreskin and prepares the area for the next stage of the procedure.

By dilating the preputial orifice and making the proximal horizontal incision with precision, we ensure adequate preparation of the surgical area and facilitate the subsequent circumcision procedure for foreskin detachment.

Step4:Retractionofthesheathanddetachmenttoremoveexcessskin

In this stage of the procedure, we proceed to retract the sheath of the penis to further expose the remaining preputial tissue. This retraction is carried out carefully to allow clear visualization of the area to be detached and to facilitate excision of the excess skin. Detachment is performed with a sterile scalpel blade to ensure a clean, precise cut. The scalpel blade is directed away from the glans to avoid damage to the underlying tissue and to minimize the risk of excessive bleeding. Once the excess skin has been excised, a careful check is made to ensure that the correct amount of tissue has been removed and that the shape of the glans is correctly exposed. Any remaining excess skin is removed to achieve an aesthetically and cosmetically pleasing final result (Figure 5).

By performing the retraction of the penile sheath and the vertical incision to release excess skin with precision, we ensure an optimal result for the patient, with adequate healing and a natural aesthetic appearance.

Step5:Horizontalsuturetobringthetwoedgestogether

In this final stage of the circumcision, a horizontal suture is used to bring the two edges of the skin together and close the wound. This suture is precisely placed to ensure adequate wound closure and promote rapid, effective healing. After excising the excess skin and exposing the glans penis, the two skin edges are carefully

aligned to ensure uniform and aesthetic wound closure. Once the skin edges are correctly positioned, sutures at the four cardinal points (3 o’clock, 6 o’clock, 9 o’clock, 12 o’clock) are used to hold the tissue in place and promote optimal healing (Figure 6). Horizontal suturing is performed using the precise surgical technique of single separate stitches to minimize the risk of bleeding and infection. Absorbable or non-absorbable sutures can be used, depending on the surgeon's preference and the patient’s specific needs. After the second horizontal suture has been performed, a careful check is made to ensure that the wound is properly closed and that the sutures are secure. Sterile dressings are then applied to protect the surgical area and promote optimal healing (Figure 7).
