Objective: To analyze mesh fixation with minimum sutures and postoperative complications. Study Design: Prospective study. Place and Duration of Study: Department of General Surgery, Thanjavur Medical College and Hospital, Tamil Nadu, from July 2010 to June 2012. Materials and Methods: All inguinal hernia patients, who fulfilled the sample selection criteria, were admitted and planned for surgery. The prolene mesh is fashioned as in Lichtenstein's repair, placed and fixed only by three prolene stitches. The first stitch is made in the periosteum of pubic tubercle. The second stitch is taken in the inguinal ligament (1.5 cm lateral to the pubic tubercle) and the third stitch is from the medial most part of the conjoint tendon, that is, the mesh is fixed in the medial aspect alone. Results: Majority of the patients fall between the age group of 40 and 60 (72%) years and all are male patients. Of the total cases, 50% were right sided, 25% were left sided, and 25% were bilateral. Of the postoperative complications, 12% had seroma, 4% had hematoma, 2% developed surgical site infection, 2% developed chronic groin pain, 1% presented with recurrence, and none developed foreign body sinus. Conclusion: The incidence of long-term complications of three stitch hernioplasty are comparable to that of the other standard, tension-free open hernia repair as well as other laparoscopic procedures. Moreover, the three stitch hernioplasty method is a simple method, easy for the beginners to adopt, has less foreign body reaction, less time consuming, causes less tissue trauma, and lesser chance for vascular injury.

| Introduction|| |
Prosthetic meshes are routinely used to repair abdominal wall hernias.,, Several techniques are used for mesh implantation, but most involve sutures to anchor a mesh in position thereby preventing migration, wrinkling, and curling. Suture placement is time consuming and often challenging. In addition, these sutures cause extensive tissue tension, predisposition to infection, and nerve entrapment, causing prolonged postoperative pain.,, Even the application of absorbable sutures instead of the nonabsorbable ones does not solve the problem. In order to avoid the above disadvantages, it was proposed that polypropylene mesh be applied with less or without suture fixation to the surrounding tissue. The aim of the study is to analyze mess fixation with minimum sutures and on its recurrence.

Patients between 20 and 60 years, who were referred to our institute for elective inguinal hernia repair from July 2010 to June 2012, were enrolled in the study after signing an informed consent. Exclusion criteria included the following: Patients more than 60 years, recurrent hernia, sliding hernia, obstructed and strangulated hernia, bladder outlet obstruction, lower respiratory infection/chronic obstructive pulmonary disease, and ischemic heart disease. Hundred inguinal hernia patients who fulfilled the sample selection criteria were admitted at Thanjavur Medical College and Hospital and was planned for surgery. For all these patients, the usual Lichtenstein's repair was not done, but a slightly modified procedure, three stitch hernioplasty, was done after getting their consent.
Three stitch hernioplasty was done with general or spinal anesthesia under antibiotic (cephalosporin 1 dose intravenous) and thromboembolic prophylaxis (low fractionated heparin subcutaneous). In this procedure, the following steps were carried out. By parainguinal incision, skin was incised and deepened to reach the external oblique aponeurosis after ligating the three named superficial subcutaneous veins. External oblique aponeurosis cut was opened along the direction of its fibers. A plane of cleavage is created between the external oblique aponeurosis and the conjoint tendon superiorly. The inguinal ligament is well defined by dissecting the floor of inguinal canal. The cremasteric muscle with cord structures is hooked out. Ilioinguinal nerve is preserved to avoid entrapment and chronic pain in the postoperative period.
Small, direct hernial sac, if present (medial to the inferior epigastric artery) must be invaginated by opposing the fibers of transversalis fascia. For large, direct hernias, the sac is opened and the transversalis fascia is repaired. In the case of indirect inguinal hernia, the sac is cut open at the fundus and the contents, if any must be reduced. Sac is transfixed at its neck and the excess sac was excised. Wide, deep ring is narrowed by suture ligation (Lytle's repair).
Now, the prolene mesh is fashioned as in Lichtenstein's repair, placed and fixed only by three prolene stitches. The first stitch is made in the periosteum of pubic tubercle. The second stitch is taken in the inguinal ligament (1.5 cm lateral to pubic tubercle) and the third stitch is from the medial most part of the conjoint tendon, that is, the mesh is fixed in the medial aspect alone [Figure 1]. Hemostasis is achieved and wound was closed in layers. Postoperatively, the patients were treated with antibiotics and analgesics and were discharged home as soon as they feel comfortable. Follow-up was scheduled at 1-week, 1-month, 3 months, 6 months, 12 months, and 24 months after surgery. In the follow-up, the patients were assessed for the development of any seroma, hematoma, wound infection, chronic groin pain, recurrence, foreign body sinus, and early return to work. Chronic groin pain (can be mild or severe) is defined as the presence of pain, discomfort, or hypersensitivity (not present before surgery) existing for more than 3 months after the surgery. Pain assessment was carried out by Visual Analog Scale (VAS) score with a score of <1 as mild, between 1 and 5 as moderate, and >5 as severe pain.

Analysis of the patient's findings showed that majority of the patients fall between the age group of 40 and 60 (72%) years and all are male patients. Of the total cases, 50% were right sided, 25% were left sided, and 25% were bilateral. Of the postoperative complications, 12% had seroma, 4% had hematoma, 2% developed surgical site infection, 2% developed chronic groin pain, 1% presented with recurrence, and none developed foreign body sinus. Low levels of postoperative pain and low complication rates were allowed for prompt physical recovery. The patients resumed their daily home activities within 2 (1–4) weeks of the operation. The operative time was found to be 95 ± 32 min.

| Discussion|| |
As inguinal hernia is a very common problem, innovations in the surgical intervention are developing day by day in order to benefit the patients by reducing the operative time and postoperative complications. Although the laparoscopic approach for hernia repair is gaining popularity, the open technique remains the operation of choice for beginners. Our goal is to assess the safety and efficacy of three stitch hernioplasty technique before a large randomized prospective study is designed to compare the results of this technique with other current approaches.
The three stitch hernioplasty technique takes advantage of the rigidity, flat-shape memory, and good adhesive features of the mesh placed in the closed anatomical space, which prevents wrinkling, curling, folding, and mesh migration. Compared to Lichtenstein's tensionless repair, the three stitch hernioplasty procedure has several practical and clinical advantages. First, minimal anchoring of the mesh to the surrounding tissue allows the surgeon to save work, thus, decreasing the time of the operation and the level of technical difficulty. The surgical dissection is limited, making the procedure less traumatic for the tissue and the patient and minimizing the predisposition for infection. The average time of the entire operation (1 h) was similar to those obtained when using Stoppa Repair or the laparoscopic approach.,
When the soft polypropylene mesh is sutured in the Rives-Stoppa technique, malformation of the mesh tension can lead to dead space formation and subsequent chronic fluid collection, hematomas, or infections. Therefore, the theoretical risk of such complications should be lowered in the three stitch technique since flat-shape-memory mesh lies flat without tension caused by fixation to the surrounding tissue.
The high level of postoperative pain at the wound and also at the edges of the prosthesis due to tissue damage and tension prolongs patient recovery. As per Lichtenstein et al., in a study performed in 1988, the incidence of chronic groin pain is 1–2%. In another study conducted in 104 patients treated by laparoscopic hernia repair by Panton and Panton in 1994, the incidence of the chronic groin pain is only 1%. In this study, the incidence of chronic groin pain is 2%. In a study conducted in Armed Force Medical College in 2010 by S.S. Jaiswal, R. Chaudhry, A. Agarwal  concluded that meticulous identification and preservation of the nerves, using absorbable suture for fixation and minimum number of sutures to fix a mesh contributed a low incidence of chronic groin pain. In our study, VAS score was checked at 1-week, 1-month, 3 months, 6 months, 12 months, and 24 months.
The two patients who had chronic groin pain at the end of 3 months had VAS score 1–3 (mild pain).
Recurrence rate in any meticulously done tension-free mesh repair or Shouldice method of hernia repair is<2%. The recurrence rate in our study is 1%, but the study was conducted only for 2 years. Only 50% of recurrence will occur in the first 2 years, and hence a minimum of 5 years of follow-up is necessary to know the efficacy of the type of hernioplasty done in our study. The patient who developed recurrence in our study was a diabetic with a large defect, thinned out musculo-aponeurotic fibres, and postoperative wound infection. The patient developed recurrence after 1-year and 5 months of hernia surgery.
Methods are designed to modify inguinal hernia repair and to decrease operating time as well as the postoperative complications such as pain, surgical site infection and hematoma, and seroma formation. This study was designed to compare the conventional mesh fixation over three stitch in terms of mean operating time and frequency of postoperative pain. Mean operating time leads to a rapid turnover of the patients. Moreover, reduced operating time has a direct implication on the working capacity of the surgeon, that is, the efficiency of the surgeon is increased. Postoperative pain is reduced if less sutures are used to anchor the mesh in inguinal hernioplasty. Decreased pain reduces stress on the patients and hastens their recovery. Quick recovery leads to early return to work and reduced work-loss days. This is an important implication not only on the natural well-being but also on the monetary aspect of the patients.
| Conclusion and Summary|| |
The incidence of long-term complications of three stitch hernioplasty are comparable to that of other standard tension-free open hernia repair as well as other laparoscopic procedures. However, the only limitation that we have in our study is the duration of follow-up. Moreover, the three stitch hernioplasty method is a simple method, easy for the beginners to adopt, has less foreign body reaction, less time consuming, causes less tissue trauma, and lesser chance for vascular injury.
