Abstract

Background and Objective: In hernioplasty by midline pre-peritoneal approach the transversalis fascia is replaced by the giant prosthetic mesh which spread beyond the myopectineal oriffice(MPO).The prosthesis envelope the visceral sac are held in place by the intra-abdominal pressure and followed by connective tissue in growth. This technique is different from the conventional meshplasty by focusing on retaining the peritoneum rather than repairing the abdominal wall defect. This is a suture-less and tension free repair. In this procedure the pre-peritoneal space is entered directly by lower midline approach without disturbing the inguinal canal, spermatic cord and the sensory nerves of the groin. It is also suited for recurrent groin hernia because the repair can be done without entering the pre-operated area so the dissection can be done without any difficulty. Methodology: Patients presented with iguinal hernia, admitted under general surgery department at LG General Hospital, Maninagar, Ahmedabad between June 2017 to September 2019 were enrolled with this study with their consents and a prospective study of 30 patients was carried out. Interpretation and conclusion: The stoppa procedure utilize the many advantage of pre-peritoneal meshplasty in inguinal hernia repair. A key feature is application of Pascal’s law in mesh placement that reinforce the lower abdominal wall with the anatomical approach without disturbing the inguinal canal. However, it requires the good dissection in the pre-peritoneal space and adequate parietalisation of the cord structures. Stoppa’s repair is an especially important hernia repair as it required less tissue dissection & in term less surgical complication and shorter duration of surgery.

Introduction

Several studies advocated the use of preperitoneal mesh placement or posterior approach. They argue that this is more effective than the traditional anterior approach because it repairs the hernia between the hernia content and defect [1]. Pascal's hydrostatic principle explains that the intra-abdominal pressure fixes the prosthesis in position, secondarily invested by the scar connective tissue [2]. The larger the prosthesis, the more efficient is the repair. Neither fixation of the prosthesis nor direct repair of necessary because of the efficiency of giant prosthesis.

Aims and Objectives

To study the method of inguinal hernia meshplasty by midline preperitoneal approach.

To evaluate the inguinal hernia meshplasty by midline preperitoneal approach with respect to Operative time, Post-operative course and complication.

Materials and Methods

Source of data

Patients presented with iguinal hernia, admitted under general surgery department at LG General Hospital, Maninagar, Ahmedabad between June 2017 to September 2019 were enrolled with this study with their consents.

Type of study

Prospective study.

Sample size

30 patients.

Operation Procedure

Anesthesia

Spinal anaesthesia given.

Position

The patient lies in a slight Trendelenburg position. The surgeon and nurse stand on one side and the assistant on the other.

Incision

After antiseptic preparation of the skin, an adhesive plastic shield is used to protect the incision from skin contamination. The abdominal wall is incised in the midline. The umbilicoprevesical fascia is cut along its entire length with Mayo scissors. The preperitoneal and prevesical cleavage is begun. Dissection progresses laterally under the rectus abdominis muscle on the side opposite the surgeon and posteriorly to the inferior epigastric vessels. The pedicle of the hernia is isolated on the side opposite the surgeon, either distinct from the spermatic cord (in direct inguinal or femoral hernias) or connected.

Sac separation and dissection

In instances of primary treatment of moderatesized hernias, continuous moderate traction followed by resection or turning inside out can be sufficient. Conversely, a strong adherent sac of a multirecurrent hernia with a large neck sometimes needs to be freed by scalpel or scissors, with a finger introduced through an opening in the peritoneal infundibulum to assist the dissection [3].

After the sac has been treated, the preperitoneal cleavage is continued easily and quickly below the external iliac vessels and laterally along the psoas muscle. It is of no use to continue this work upward beyond the line of Douglas, where the peritoneum is adherent and prone to tearing. The cleavage of the spaces of Retzius and Bogros is done quickly and easily, with a single, flat retractor placed under the abdominal wall and the surgeon's left hand, displacing peritoneum. The parietalization of the component the spermatic cord greatly simplifies placement of the giant prosthesis so opening the mesh to allow passage of spermatic cord is not required. Now the surgeon changes side to achieve the retroperitonal cleavage on the opposite side whichs proceeds as described previously [3].

Placement of the giant prosthesis

The prosthesis should be measured directly on the patient to allow the implantation of the largest piece possible. The mean dimensions are 26 cm transversely and 15 cm vertically. The prosthesis is then cut into a chevron shape according to the patient's measurements. A notouch technique is mandatory [4]. The giant prosthesis is then simply spread out in place by grasping its corners and the middle of each side with eight long Kelly forceps [5].

The prosthesis is first positioned on the side opposite the surgeon. While the assistant lifts and retracts the abdominal wall, the surgeon displaces the perito-neum with' his or her left hand toward himself or herself and upward, thereby opening the cleavage plane. Placement is achieved by pushing the prosthesis into position with the Kelly-forceps. The forceps on the middle lower margin of the mesh are placed first between the pubis and the urinary bladder, followed successively by the forceps on the inferior lateral corner, the middle point of the lateral mar-gin, and finally the upper lateral corner [6,7]. The forceps are pushed as far as possible under the abdominal wall, thereby unfolding the mesh and placingit at the inferior, lateral ad posterior limits of the retroperitoneal dissection [8].

In this way, the prosthesis envelops the peritoneum on the side opposite the surgeon. The surgeon again changes the sides and repeats the same procedure on the other side. This method of implantation leads to full unfolding of the Dacron mesh, which now widely envelops the peritoneum and extends well beyond the limits of both the myopectineal holes and protects the midline subumbilical incisional wound [9]. One single stitch of slowly absorbing material fixes the middle of the upper edge of the mesh to the lower margin of the Richert’s umbilical fascia (Figure 1).

Closure and drainage

When necessary, suction drains installed anterior to the prosthesis in the space of Retzius.

Discharge

All the patients were discharged after 3-5 days of surgery.

All patients given oral Amoxicillin plus clavulinic acid for 7 days and oral diclofenac sodium 50 mg BD for 2 days and then as per required.

Follow up

All the patients were followed up on 3rd, 7th, 30th post-operative day and at 3 months and 6 months.

Observation And Results

In this present study, 30 patients diagnosed as uncomplicated inguinal hernia (direct,indirect or bilateral) were taken for study during Jun, 2017 to October 2019. Operative and post-operative details were collected from case papers and confirmed by asking questions and systemic examination done during follow up. The median follows up duration was 6 months.

maximum hernia occurs above 50 years of age (63.3%). The maximum age at time of operation was 75

years and minimum age were 24 years.

Gender distribution

All the patients are male.

Type of hernia

Bilateral direct hernia is common in old age group. Total 33.3% cases are of bilateral direct inguinal hernia (Figure 2).

Associated complain

7 patients had chronic cough, for which medication was started preoperatively. Cough was brought under control and then patient was posted for surgery. 6 patients had chronic constipation, for which laxatives were given preoperatively. 3 patients had prostatism for which tamsulosin was started nad continued postoperatively for at least 3 months. 13 patients were chronic smokers among which 3 had associated complaint of chronic cough for which proper preoperative respiratory assessment was done.

Duration of surgery

Shortest duration of surgery was 50 minutes which was for right side direct inguinal hernia.

Longest duration of surgery was 100 minutes which was for bilateral indirect inguinal hernia.

Average duration of surgery was 85.4 minutes.

This is the observational study consisting of 30 patients of uncomplicated inguinal hernia who underwent Stoppas repair in th Department of General Surgery, LG Hospital – AMC MET Medical College, Ahmedabad in the period if 2017 – 2019 which included average 6 months follow up.

This study is compared with similar type of studies held previously like:

A study of giant prosthesis reinforcement of visceral sac: The Stoppa groin hernia repair in 234 patients done by Hemmant et al. during the period of 20th March 1995 and 20th March 2003 [10].

Stoppas repair for inguinal hernia: Still an Ideal Procedure done by Durgama et al. A study of 250 cases from August 2005 to May 2014 [11]. A 80 case study of Stoppa repair done be Varun et al. during period of April 2014 to April 2017 [12].

Majority of the patients (63.3%) were above 50 years of age. A similar study done by Hemmant et al. 58% of patients were above 50 years of age. In another study done by Durgama et al. 55% of the patients were above 50 years of age. All the patients were male [10].

In our study, 36.6% patients had bilateral direct hernia. 26.6% patients had mixed hernia (one side direct+one side indirect). ^.67% patients had bilateral indirect hernia. Others were unilateral hernia.

In a similar study 27.5% were bilateral indirect hernia, 32.5% were bilateral direct hernia and 10% were mixed (contrary to our study).

The mean operative time in our procedure was 85.4 minutes. Shortest was 50 minutes for right side direct hernia and longest was 100 minutes for bilateral indirect hernia. A similar study done by Hemmant et al. mean operative time was 54 minutes (30-75 min range) [10]. In another study done by Durgama et al. mean operative time was 52 minutes [11].

In our study, mean period of hospital stay was 4 days. A similar study done by Hemmant et al. [10] mean period of hospital stay was 2.2 days. In another study done by Durgama et al. mean period of hospital stay was 3.5 days [11].

In our study, 1 patient (33.3%) had a complication of urinary retention. In a similar study none of the patients had complaint of urinary retention.

In our study 2 patients (6%) developed seroma. In a similar study by Hemmant and colleagues, 3% patients developed seroma [10].

In our study, 1 patient (3%) developed superficial surgical site infection. A similar study done by Hemmant et al. none of the patients developed surgical site infections [10].

In our study, 1 patient (3%) developed recurrence. A similar study done by Hemmant et al. [10] 1.55% patients developed recurrence. In another study done by Durgama et al. [11] 1.6% patients developed recurrence. In another similar 2.55% patients developed recurrence.

In our study, none of the patients developed hematoma, neuropathy, scrotal swelling or any major intra-operative injury. None of the patients required post-operative mesh extraction.

In our study, patients were able to return to normal daily activity in 12.7 days. A similar study done by Hemmant et al. [10] mean period of return to normal activity was 14 days. In another study mean period of return to normal activity was 16 days.

Conclusion

The stoppa procedure utilize the many advantage of pre-peritoneal meshplasty in inguinal hernia repair. A key feature is application of Pascal’s law in mesh placement that reinforce the lower abdominal wall with the anatomical approach without disturbing the inguinal canal. However, it requires the good dissection in the preperitoneal space and adequate parietalisation of the cord structures.

?? It is a preferred procedure in many clinical scenarios because

?? It allows the single incision for bilateral hernia and cover the entire myopectineal orifice so prevent direct indirect and femoral hernia.

?? In case of recurrent hernia done by lichtenstein hernioplasty dissection can be done without entering the operated plane.

?? Cord dissection not required so less chances of scrotal oedema, ischemic orchitis & testicular atrophy.

?? As the sensory nerves of groin (ilioinguinal and iliohypogestric) are not disturbed less chances of chronic pain.

?? Operative time is less for bilateral hernia in compare to anterior inguinal hernia repair simultaneously for both side and also in compare to laparoscopic repair.

Stoppa’s repair is an especially important hernia repair as it required less tissue dissection & in term less surgical complication and shorter duration of surgery. Mesh fixation (if required) is also adequate as the optimum point which may lead to less chances of recurrence.
