Good day Doctors! Respectfully posting my assignment given to me by Dr. Angel Katrina Cantero on tissue-based and laparoscopic approaches on hernia repair
Tissue-Based Repair:
1.) Bassini Repair
- This begins with dissection of the spermatic cord and high ligation of the hernia sac. The transversalis fascia is then incised from the p***c tubercle to the internal inguinal ring, and the preperitoneal fat is mobilized to allow adequate tissue movement. A triple-layer repair is performed by suturing the internal oblique muscle, transversus abdominis muscle, and transversalis fascia to the inguinal ligament and p***c periosteum with interrupted sutures, thereby reconstructing the posterior wall of the inguinal canal and reinforcing the medial border of the internal inguinal ring.
2.) Shouldice Repair
- a modification of the Bassini repair that distributes tension across multiple tissue layers, resulting in lower recurrence rates. After dissection of the spermatic cord, the ge***al branch of the genitofemoral nerve is routinely divided, and the transversalis fascia is incised from the p***c tubercle to the internal inguinal ring. The superior and inferior fascial flaps are mobilized, and a continuous four-layer repair is performed by suturing the transversalis fascia, iliop***c tract, internal oblique, and transversus abdominis to the inguinal ligament and external oblique aponeurosis, creating a strong reconstruction of the posterior inguinal wall with reduced tension.
3.) McVay Repair
- a tissue-based technique that repairs both inguinal and femoral hernias, making it the preferred tissue repair for femoral hernias and for cases where mesh is contraindicated. After isolating the spermatic cord, the transversalis fascia is incised to enter the preperitoneal space, and Cooper's ligament is exposed. A 2–4 cm relaxing incision is made in the anterior re**us sheath to reduce tension. The superior transversalis fascia flap is then sutured to Cooper's ligament to close the femoral ring, followed by a transition stitch and lateral fixation of the transversalis fascia to the inguinal ligament, completing the repair.
4,) Desarda Repair
- a mesh-free tissue repair that uses an undetached strip of the external oblique aponeurosis (EOA) to reinforce the posterior wall of the inguinal canal. After an oblique incision, the spermatic cord is isolated and the hernia sac is excised (or inverted in small direct hernias). The medial leaf of the EOA is sutured to the inguinal ligament, and a strip of the EOA is created by a splitting incision while keeping it attached. The free edge of this strip is then sutured to the internal oblique muscle or conjoint tendon, forming a new posterior wall of the inguinal canal. The wound is then closed in the usual manner.
Laparoscopic Approach
1.) Transabdominal Preperitoneal (TAPP) Repair
- This technique enters the peritoneal cavity laparoscopically, after which the peritoneum overlying the inguinal region is incised to access the preperitoneal space. The hernia sac is reduced, and a prosthetic mesh is placed over the entire myopectineal or***ce to cover both direct and indirect defects. The peritoneum is then closed over the mesh, separating it from the abdominal contents. TAPP provides a broad view of the groin anatomy and allows evaluation of the contralateral side but requires entry into the abdominal cavity, carrying a small risk of intra-abdominal injury.
2.) Totally Extraperitoneal (TEP) Repair
- The TEP approach repairs the hernia without entering the peritoneal cavity. A working space is created in the preperitoneal plane, where the hernia sac is reduced and a mesh is placed over the myopectineal or***ce. Since the peritoneal cavity is not entered, TEP reduces the risk of bowel injury and postoperative intra-abdominal adhesions. However, it is technically more challenging and offers a smaller operative field than TAPP.
