BACKGROUND: Refractory neuropathic inguinodynia following inguinal herniorrhaphy is a common and debilitating complication. This prospective study evaluated long-term outcomes associated with laparoscopic retroperitoneal triple neurectomy. METHODS: Sixty-two consecutive patients (51 male; mean age, 47); all failing pain management; prior reoperation in 35, prior neurectomy in 26; average follow-up 681 days (range: 90 days to 3 years). Measured outcomes include numeric pain ratings, dermatomal mapping, histologic confirmation, quantitative sensory testing, complications, narcotic usage, and activity level...

BACKGROUND: Chronic postherniorrhaphy inguinal pain (CPIP) is a complex, major health problem. In the absence of recurrence or meshoma, laparoscopic retroperitoneal triple neurectomy (LRTN) has emerged as an effective surgical treatment of CPIP. METHODS: This prospective pilot study evaluated the neurophysiological and clinical effects of LRTN. Ten consecutive adult CPIP patients with unilateral predominantly neuropathic inguinodynia underwent three comprehensive quantitative sensory testing (QST) assessments (preoperative, immediate postoperative, and late postoperative)...

Inguinal hernia repair is one of the most common surgeries performed worldwide. With the success of modern hernia repair techniques, recurrence rates have significantly declined, with a lower incidence than the development of chronic postherniorrhaphy inguinal pain (CPIP). The avoidance of CPIP is arguably the most important clinical outcome and has the greatest impact on patient satisfaction, health care utilization, societal cost, and quality of life. The etiology of CPIP is multifactorial, with overlapping neuropathic and nociceptive components contributing to this complex syndrome...

IMPORTANCE: With the technical success of tension-free inguinal herniorrhaphy, chronic groin pain has far surpassed recurrence as the most common long-term complication. OBJECTIVE: To evaluate laparoscopic triple neurectomy of the ilioinguinal, iliohypogastric, and genitofemoral nerve trunks in the retroperitoneal lumbar plexus for treatment of refractory inguinodynia. DESIGN: Prospective study. SETTING: University hernia center...

BACKGROUND: Standard triple neurectomy does not address inguinodynia secondary to neuropathy of the genitofemoral nerve and the preperitoneal segment of its genital branch seen after inguinal hernia repair performed laparoscopically or in open preperitoneal fashion. STUDY DESIGN: Standard triple neurectomy was extended to include the genitofemoral nerve. Sixteen patients with chronic groin pain after laparoscopic and open preperitoneal inguinal hernia repair underwent operative triple neurectomy, with resection of the main trunk of the genitofemoral nerve in the retroperitoneum over the psoas muscle...

A linear quantitative structure-activity relationship (QSAR) model is presented for the modelling and prediction for the interleukin-1 receptor associated kinase 4 (IRAK-4) inhibition activity of amides and imidazo[1,2-α] pyridines. The model was produced using the multiple linear regression (MLR) technique on a database that consisted of 65 recently discovered amides and imidazo[1,2- α] pyridines. Among the different constitutional, topological, geometrical, electrostatic and quantum-chemical descriptors that were considered as inputs to the model, seven variables were selected using the genetic algorithm subset selection method (GA)...

Diabetic rats display increased pain responses after injection of formalin into the paw or thermal stimulation of the tail, suggesting the presence of hyperalgesia. In this study, we investigated the efficacy of URB597 (0.1, 0.3, and 0.5 mg/kg, i.p.), an inhibitor of endocannabinoids metabolism, on 2 models of experimental hyperalgesia in streptozotocin (STZ)-induced diabetic rats. Animals were divided into control, URB597-treated control (0.1, 0.3, and 0.5 mg/kg), diabetic, and URB597-treated diabetic (0.1, 0...

REVIEW
Parviz K Amid
Since the introduction of the Bassini method in 1887, more than 70 types of pure tissue repair have been reported in the surgical literature. An unacceptable recurrence rate and prolonged postoperative pain and recovery time after tissue repair along with our understanding of the metabolic origin of inguinal hernias led to the concept of tension-free hernioplasty with mesh. Currently, the main categories of inguinal hernia repair are the open repairs and the laparoscopic repairs. In the open category, repair of the hernia is achieved by pure tissue approximation or by tension-free mesh repair...

Parviz K Amid
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...

Parviz K Amid
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...

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...
