Total extra-peritoneal repair of groin hernia: prospective evaluation at a tertiary care center

Totally Extraperitoneal Repair in Inguinal Hernia: More Than a Decade's Experience at a Tertiary Care Hospital

INTRODUCTION

There are 2 standard techniques of laparoscopic groin hernia repair, totally extraperitoneal repair (TEP) and transabdominal preperitoneal repair (TAPP). TEP has the advantage that the peritoneal cavity is not breached but is, however, considered to be more difficult to master when compared with TAPP. We describe herein our experience of TEP repair of inguinal hernia over the last 14 years.

MATERIALS AND METHODS

This study is a retrospective analysis of a prospectively maintained database of all patients with groin hernia who underwent TEP repair in a single surgical unit between January 2004 and January 2018. Patients' demographic profile and hernia characteristics (duration, side, extent, content, and reducibility) were noted in the prestructured proforma. Clinical outcomes included the operation time, intraoperative and postoperative complications, length of postoperative hospital stay, hernia recurrence, chronic pain, recurrence, seroma, and wound infections. Long-term follow-up was carried out in the outpatient department.

RESULTS

Over the last 14 years, TEP repair was performed in 841 patients and a total of 1249 hernias were repaired. The mean age of patients was 50.7 years. There were 748 primary and 345 unilateral hernias. The majority were direct (61%) inguinal hernias. Telescopic dissection was the commonest method of space creation. The average operating time was 54.8 and 77.9 minutes for unilateral and bilateral hernias, respectively. With 81 conversions, the success rate for TEP was 93.5%. Seroma was the most common postoperative complication seen in 81 patients. The incidence of chronic groin pain was 1.4%. The follow-up ranged from 3 months to 10 years, and there were only 3 recurrences (<1%).

CONCLUSION

In conclusion, TEP repair is an excellent technique of laparoscopic inguinal hernia repair with acceptable complications after long-term follow-up.

Laparoscopic Single-Site Inguinal Hernia Repair Using a Self-Fixating Mesh

Background and Objectives:

Every year ∼20 million inguinal hernia repairs are completed worldwide. Increased patient access to medical information and education has elicited interest in minimally invasive surgical techniques that obtain improved surgical outcomes and cosmesis. Because of these factors, there is a growing interest in single-incision surgery. Laparoscopic totally extraperitoneal (TEP) single-incision hernia repair technique has been reported with different meshes used in a tack fixation system. Recently, self-fixating mesh technology has offered the possibility of avoiding tack fixation and potentially avoiding chronic postoperative pain. Self-fixating mesh technology employs monofilament polylactic acid (PLA) creating a microgrip system that provides self-adherence of the mesh to adjacent tissue. This tack-free fixation system provides coverage over the entire myopectineal orifice and surrounding areas where traditional tacks cannot be placed. Self-fixating mesh has also been safely applied in laparoscopic TEP procedures, but this mesh has not been described in single site TEP surgery; possibly because of the potential difficulty with mesh deployment. We sought to determine the technical feasibility of a single-site laparoscopic TEP repair of inguinal hernias and to discuss our techniques and patient short-term outcomes.

Methods:

Review of a prospectively maintained database of patients who received single-site laparoscopic TEP herniorrhaphy from August 2012 through August 2015. Patient characteristics and demographics and perioperative and postoperative data were analyzed.

Results:

Thirty-four patients (aged 55.2 ±14.2; 17.6% women) with a mean body mass index of 26.2 ± 3.9 were analyzed. Mean operative time was 99.5 ± 30.5 minutes, 41.2% were left-side repairs, and 50% were bilateral. Estimated blood loss was 18.4 ± 14.1 mL. Recurrent hernias accounted for 14.7% of cases; 32.4% of cases were combination surgeries, most commonly a concurrent umbilical hernia repair. The most common short-term postoperative complication was urinary retention (4 patients). The median length of follow-up was 25 days (IQR 18.75–61.75). Complications occurring at >30 days included hydrocele (2 patients) and stitch abscess (1 patient). Eight (23.5%) patients had complications (surgical or during follow-up). No recurrences or deaths were reported.

Conclusions:

With comparable operative times, perioperative outcomes, and safety profile, SS-TEP appears to be a safe and effective surgical approach for the management of inguinal hernias in the short term. Furthermore, SS-TEP with a self-fixating mesh is a feasible approach.

Laparoscopic treatment for inguinal hernia combined with cryptorchidism: Totally extraperitoneal repair with orchiectomy under the same operative view

•

We treated two patients with right indirect inguinal hernias and cryptorchidism.

•

Both patients underwent TEP repair with orchiectomy under the same operative view.

•

TEP repair with orchiectomy could be safely performed.

•

This procedure could be an option for the treatment of such adult patients.

Introduction

Approximately 7% of child patients with inguinal hernias also present with cryptorchidism. On the other hand, combined adult cases are uncommon. Here we report two adult cases of inguinal hernia combined with intra-canalicular cryptorchidism who underwent totally extraperitoneal (TEP) repair with orchiectomy under the same operative view.

Presentation of cases

We treated two patients (49- and 38-year-old men) with right indirect inguinal hernias and cryptorchidism. Both patients underwent TEP repair with orchiectomy. In operative findings, an atrophic testis was drawn out with a hernia sac from the internal inguinal ring. After the testis was separated from the sac and cord structure was sheared, it was removed. The procedure did not require special techniques and devices. In both patients, the postoperative courses were satisfactory.

Discussion

To our knowledge, there has been only one such reported case till date which demonstrated the feasibility of TEP repair accompanied by orchiectomy.

Conclusions

TEP repair with orchiectomy under the same operative view could be safely performed in adults with an inguinal hernia combined with extra-abdominal cryptorchidism. This procedure could be an option for the treatment of such adult patients.

Laparoscopic inguinal hernia repair in the Armed Forces: A 5-year single centre study

BACKGROUND

Surgery for inguinal hernia continues to evolve. The most recent development in the field of surgery for inguinal hernia is the emergence of laparoscopic inguinal hernia surgery (LIHS) which is challenging the gold standard Lichtenstein's tension free mesh repair. Our centre has the largest series of LIHS from any Armed Forces hospital. The aim of this study was to analyze the short and long term outcomes at our center since its inception.

METHODS

Retrospective review of prospectively maintained data base of 501 LIHS done in 434 patients by a single surgeon between April 2008 and October 2013. Preoperative, intraoperative, postoperative and follow-up data was analyzed with emphasis on the recurrence rates and the incidence of inguinodynia.

RESULTS

402 (92.6%) patients had primary hernias and 367 (84.6%) patients had unilateral hernias. Of the 501 repairs, 453 (90.4 %) were done totally extraperitoneal approach and 48 (9.6 %) were done by the transabdominal preperitoneal approach. The mean operative time for unilateral and bilateral repairs was 40.9 ± 11.2 and 76.2 ± 15.0 minutes, respectively. The conversion rate to open surgery was 0.6%. The intraoperative, and early and late postoperative complication rates were 1.7%, 6.2% and 3%, respectively. The incidence of chronic groin pain was 0.7% and the recurrence rate was 1.6%. The median hospital stay was 1 day (1-5 days).

CONCLUSION

We, in this series of over 500 repairs have demonstrated that feasibility as well as safety of LIHS at our centre with good short and long term outcomes.

Laparoscopic inguinal hernia repair: a prospective evaluation at Eastern Nepal

Introduction

Inguinal hernias have been treated traditionally with open methods of herniorrhaphy or hernioplasty. But the trends have changed in the last decade with the introduction of minimal access surgery.

Methods

This study was a prospective descriptive study in patients presenting to Surgery Department of B. P. Koirala Institute of Health Sciences, Dharan, Nepal with reducible inguinal hernias from January 2011 to June 2012. All patients >18 years of age presenting with inguinal hernias were given the choice of laparoscopic repair or open repair. Those who opted for laparoscopic repair were included in the study.

Results

There were 50 patients, age ranged from 18 to 71 years with 34 being median age at presentation. In 41 patients, totally extraperitoneal repair was attempted. Of these, 2 (4%) repairs were converted to transabdominal repair and 2 to open mesh repair (4%). In 9 patients, transabdominal repair was done. The median total hospital stay was 4 days (range 3-32 days), the mean postoperative stay was 3.38±3.14 days (range 2-23 days), average time taken for full ambulation postoperatively was 2.05±1.39 days (range 1-10 days), and median time taken to return for normal activity was 5 days (range 2-50 days). One patient developed recurrence (2%). None of the patients who had laparoscopic repair completed complained of neuralgias in the follow-up.

Conclusion

Laparoscopic repair of inguinal hernias could be contemplated safely both via totally extra peritoneal as well as transperitoneal route even in our setup of a developing country with modifications.

A prospective, randomized comparison of long-term outcomes: chronic groin pain and quality of life following totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) laparoscopic inguinal hernia repair

BACKGROUND

Data are insufficient to compare transabdominal preperitoneal repair (TAPP) and total extraperitoneal (TEP) techniques of laparoscopic inguinal hernia repair. There is very scant data comparing the two techniques in terms of long-term outcomes, which include chronic groin pain, quality of life, and time to return to normal activity. This prospective, randomized, controlled trial compared TEP versus TAPP techniques of laparoscopic inguinal hernia repair in terms of these long-term outcomes.

METHODS

This study was conducted from May 1, 2007 to March 30, 2012. Patients with uncomplicated groin hernia were randomized to transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) techniques. A total of 160 patients were randomized to group I (TEP) and 154 patients to group II (TAPP). Pain was assessed with Visual Analogue Scale (VAS) preoperatively and postoperatively at 24 h, 1 week, 6 weeks, 3, 6, and 12 months, and yearly thereafter. Quality of life was assessed with Short Form-36 version 2 (SF 36v2) preoperatively and postoperatively at 3 months follow-up.

RESULTS

Demographic, clinical profiles, intraoperative, and early postoperative parameters were well matched. There was significantly higher acute pain following TAPP repair; however, the chronic groin pain was comparable in both TEP and TAPP. Preoperative pain and immediate postoperative pain had significant correlation with chronic groin pain. Significant improvement from preoperative to postoperative quality of life was seen in both TEP and TAPP repairs, but there was no difference between TEP and TAPP in postoperative period. Time to return to normal activity also was similar between the two groups.

CONCLUSIONS

The TEP and TAPP techniques of laparoscopic repair of inguinal hernia have comparable long-term outcomes in terms of incidence of chronic groin pain, quality of life, and resumption of normal activities. Chronic groin pain had a significant correlation with preoperative pain and early postoperative pain. However, TAPP was associated with significantly higher incidence of early postoperative pain, longer operative time, and cord edema, whereas TEP was associated with a significant higher incidence of seroma formation. The cost was comparable between the two.

Laparoscopic inguinal hernia repair: transabdominal preperitoneal (TAPP) versus totally extraperitoneal (TEP) approach: a prospective randomized controlled trial

BACKGROUND

Minimal access approaches to inguinal hernia repair have added to the ongoing debate over the "best groin hernia repair." The present prospective randomized controlled trial was done to compare the totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) techniques of laparoscopic inguinal hernia repair.

METHODS

The present prospective randomized study was conducted between May 2007 and March, 2009 and included 100 patients suffering from uncomplicated primary groin hernia. Patients were randomized into group I (TEP) and group II (TAPP). Intraoperative variables and postoperative pain scores were recorded in a prestructured form.

RESULTS

One hundred patients were included in the study (TEP, 53; TAPP, 47). Both groups were comparable in terms of demographic profile and hernia characteristics. The average operative time was higher in the TAPP group (p = 0.209). The pain scores at 1 h and 24 h after surgery and at 3-month follow-up were significantly higher in the TAPP group (p < 0.05). The average follow-up was 30.5 months. In the TEP group, 37.8% of patients had seroma compared to 18.3% in the TAPP group (p = 0.021). However, there was a higher incidence of scrotal edema in the TAPP group (16 vs. 9, p = 0.009). The wound infection rates were equal (2% vs. 3%). There has been no recurrence in either group during the follow-up period of 44 months. Overall, the patients were more satisfied with TEP rather than TAPP (p < 0.05).

CONCLUSIONS

In the present study, TEP had a significant advantage over TAPP for significantly reduced postoperative pain up to 3 months, which resulted in a better patient satisfaction score. The other intraoperative complications, postoperative complications, and cost were similar in both groups. In terms of results, both repair techniques seemed equally effective, but TEP had an edge over TAPP.

Massive scrotal hernias: problems and solutions

BACKGROUND

Massive incarcerated scrotal hernias are usually managed by an open method. Some experienced surgeons have successfully attempted laparoscopic management of such cases. Total extraperitoneal repair (TEP) is the laparoscopic technique of choice for the repair of groin hernia. Many authors have suggested that transabdominal preperitoneal (TAPP) is the preferred approach to these hernias. The purpose of this study is to show our results of TEP repair of giant scrotal hernias.

PATIENTS AND METHODS

In the present study a total of 21 (20 patients) out of 291 groin hernias (185 patients) were included and evaluated prospectively. TEP was successful in 14 (66.6%) with a conversion to TAPP in 4 (19.04%) and open procedure in 3 (14.28%) cases, respectively. Postoperative complications included scrotal hematoma in 5 (25%), spermatic cord edema in 6 (30%), and seroma in 14 (70%) patients. There was no recurrence of hernia noticed during mean follow-up of 36 months (range, 22-51).

CONCLUSION

Laparoscopic TEP repair was successful with excellent outcome in the management of massive incarcerated groin hernia in the hands of an experienced laparoscopic surgeon.
