Lichtenstein tension-free hernioplasty: its inception, evolution, and principles.

To circumvent the degenerative nature of inguinal hernias and adverse effect of suture line tension, the Lichtenstein tension-free hernioplasty began in 1984 and evolved (between 1984 and 1988) to a procedure that is now considered the gold standard of hernia repair by the American College of Surgeons. The objective of this paper is to outline the reasons behind the minor changes made during the short, 4-year evolution of the technique, describe the key principles of the operation, and introduce a new mesh that, if elected to be used, automatically satisfies all the key principles of the procedure and guides the surgeon to perform the operation correctly. The worldwide reported result of the operation by experts and nonexperts alike is a recurrence and complication rate of less than 1%. When the key principles of the procedure, which, as reported by many authors, are easy to learn, perform, and teach, are respected, the operation results in an effectiveness (external validation) that is virtually the same as its efficacy (results of the experts), attesting to the simplicity of the procedure.

A 1-stage surgical treatment for postherniorrhaphy neuropathic pain: triple neurectomy and proximal end implantation without mobilization of the cord.

BACKGROUND: The recommended surgical treatment for chronic neuropathic pain after herniorrhaphy has been a 2-stage operation including: (1) ilioinguinal and iliohypogastric neurectomies through an inguinal approach and (2) genital nerve neurectomy through a flank approach. HYPOTHESIS: A 1-stage surgical procedure resecting all 3 nerves from an anterior approach avoids a second operation through the flank and successfully treats chronic neuralgia. SETTING: A private practice dedicated to abdominal wall hernia surgery in general community hospitals. PATIENTS: Between 1995 and 2001, 49 patients underwent triple neurectomies with proximal end implantation to treat chronic postherniorrhaphy neuralgia. INTERVENTION: Triple neurectomy of the ilioinguinal, iliohypogastric, and genital nerves performed under local anesthesia with implantation of their proximal ends and without mobilization of the spermatic cord. RESULTS: Two patients (4%) reported no improvement. Eighty percent of patients recovered completely, and 16% had transient insignificant pain with no functional impairment. These results are comparable to the results of the 2-stage operation. CONCLUSIONS: Simultaneous neurectomy of the ilioinguinal, iliohypogastric, and genital nerves without mobilization of the spermatic cord is an effective 1-stage procedure to treat postherniorrhaphy neuralgia. It is performed under local anesthesia and avoids testicular complications. Proximal end implantation of the nerves prevents adherence of the cut ends to the aponeurotic structure of the groin, which can result in recurrence of the pain.

How to avoid recurrence in Lichtenstein tension-free hernioplasty.

The following key principles of the Lichtenstein tension-free hernioplasty can help avoid recurrence and decrease postoperative pain: (1) Use a large sheet of mesh that will extend approximately 2 cm medial to the pubic tubercle, 3 to 4 cm above Hesselbach's triangle, and 5 to 6 cm lateral to the internal ring. (2) Cross the tails of the mesh behind the spermatic cord to avoid recurrence lateral to the internal ring. (3) Secure the mesh with two interrupted sutures on the upper edge and one continuous suture with no more than 3 to 4 passes on the lower edge of the mesh to prevent folding and movement of the mesh in the groin. (4) Position the mesh in a slightly relaxed dome shape configuration to counteract the forward protrusion of the transversalis fascia when the patient stands up from the intraoperative supine position. (5) Identify and protect the ilioinguinal, iliohypogastric, and genital nerves throughout the operation.
