About

Inguinal hernia repair is done by two methods. The conventional method uses a prosthetic mesh for strengthening the defect but has been associated with complications. Another new method uses a strip of the external oblique aponeurosis to do the same.There is a necessity to conduct studies comparing the two methods of hernia repair under local anaesthesia in terms of feasibility, economic benefits, faster ambulation with less complications. The purpose of the study is to find a method that will lead to faster disposal of patients and early return to activities, thereby reducing the waiting list of patients that compromises their financial and social spheres and overwhelms the welfare system.

Full description

Inguinal hernia is one of the most common treatable surgical conditions. The synthetic prostheses most often used in the inguinal area may in some cases create new clinical problems, such as foreign body sensation in the groin, discomfort, and abdominal wall stiffness, surgical site infections, migration of mesh and may affect procreation and sexual function, The cost and availability of mesh prostheses in smaller towns and underdeveloped regions proves to be a major hindrance. The requirement of the hour is to find a technique that is simple, cost effective, easy to perform, does not require extensive dissection or use of a foreign body, and also gives an acceptable recurrence rate without any major intra or post-operative complications and can be performed as a day care procedure to reduce the burden of cases in our community. A possible option for this is the Desarda method, presented in 2001, which uses an undetached strip of aponeurosis of the external oblique muscle instead of a mesh and has shown to have promising results in studies conducted so far. Several retrospective and randomized controlled trials have shown that local anaesthesia provides the best clinical and economic benefits to patients undergoing inguinal hernia repair. As there have been no studies till date comparing the outcomes for patients operated by these methods under local anaesthesia only, hence this study has been planned to assess if Desarda's technique is suitable to be used as a day care procedure with early return to normal activities after surgery, less post operative discomfort and minimum dose of analgesics and acceptable recurrence rates. This will help reduce the burden of the hospitals as these patients can be operated on a day care basis with minimal discomfort.

55 participants in 2 patient groups

Desarsda's technique

Experimental group

Description:

These patients wil be operated by the Desarda's technique without using any prosthetic mesh. A strip of external oblique aponeurosis will be used to strengthen the defect. Both field block and local infiltration with tumescent anaesthesia techniques will be used for anaesthesia Intervention: A strip will be separated from the upper leaf of the external oblique aponeurosis keeping its insertion and continuity with the muscle intact. This strip will be sutured with the inguinal ligament below and the muscle arch or conjoint tendon above behind the spermatic cord to form the new inguinal floor. Continuous non absorbable prolene 2-0 suture will be used to secure it to the inguinal ligament inferiorly , and will be secured superiorly to the internal oblique muscle using interrupted absorbable vicryl sutures.

Treatment:

Procedure: Desarda's technique

Lichtenstein's technique

Active Comparator group

Description:

These patients will be operated using prosthetic mesh described as Lichtenstein's tension free mesh hernioplasty. Both field block and local infiltration with tumescent anaesthesia techniques will be used for anaesthesia. Intervention : A 6 × 11 cm polypropylene mesh will be fashioned to fit the posterior wall of the inguinal canal and sutured to the fibro-periosteum of the pubic bone and continued laterally, suturing the inferior edge of the mesh to the shelving edge of the inguinal ligament to a point 2 cm lateral to the internal ring. Laterally, 2 cm silt will be made through the mesh to accommodate the cord. while the two tails will be sutured to create a new deep ring made of mesh.

Treatment:

Procedure: Lichtenstein's technique
