Surgical outcome and hospital cost analyses of laparoscopic and open tension-free hernia repair

Abstract Surgeons who favor the laparoscopic repair of groin hernias must limit the additional costs associated with this technique, which is not universally acknowledged to be superior to other less expensive open tension-free repairs. This retrospective study compared outcome and costs between laparoscopic and open tension-free hernia repair in 320 patients with inguinal hernias. Patients underwent either (a) transabdominal preperitoneal procedure (TAPP; 60 patients, 72 procedures), (b) totally extraperitoneal procedure (TEP; 174 patients, 202 procedures), or (c) open tension-free procedure (86 patients, 105 procedures). Regarding important postoperative complications there were two (3.3%) recurrences in the TAPP group and one (0.6%) in the TEP group, and six (9.9%) transient neuralgias in the TAPP group and one (1.2%) in the tension-free group. There were no deaths, no testicular atrophies, and no wound or mesh infections. The mean hospital postoperative stay was the same in the three groups (1 day). Mean operating time was shorter in the tension-free group concerning the unilateral cases and shorter in the TEP group concerning the bilateral cases. Fewer patients required analgesia during the first 6 h after the operative procedure in the TEP group than in the other two groups. The mean total costs were 483.90 euros in the open tension-free repair, 763.20 euros in the TAPP repair, and 572.50 euros in the TEP repair. The open procedure was the cheaper for the hospital. Laparoscopic hernia repair and tension-free repair as described by Gilbert are comparable in postoperative complications. TEP hernia repair is associated with less postoperative pain and earlier return to normal activities, but it is more expensive and continues to be a difficult procedure. Open tension-free repair is the least expensive method and is easier to learn than the other two procedures. Electronic Publication     

Laparoscopic repair of inguinal hernias with higher risk for recurrence: independent assessment of results from 121 repairs

This study attempts to determine by independent review the results of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair for hernias with increased risk for recurrence. Indicators used for increased recurrence risk were recurrent hernias or simultaneously repaired bilateral inguinal hernias. Office and hospital records of all such patients who had undergone TAPP repair were reviewed from one surgeon's 242-patient laparoscopic inguinal hernia database from 1992 to 1998. All were called for assessment by an independent surgeon at least 4 months postoperatively (median 34 months). Those unable to come in person were interviewed by telephone. There were 121 hernias: 34 recurrent and 100 bilateral (13 overlap). Recurrence rate was 3 per cent, which was similar for repair of bilateral and recurrent hernias. All recurrences occurred within 3 months of surgery. No unknown recurrence was detected by the independent observer. Laparoscopic TAPP inguinal hernia repair, often claimed as the method of choice for bilateral and recurrent hernia repair, is indeed a safe and effective procedure with a low early recurrent rate in these higher-risk situations.     

Laparoscopic repair of recurrent hernias

BACKGROUND: Recurrence after primary conventional inguinal herniorrhaphy occurs in approximately 10% of patients depending on the type of repair and expertise of the surgeon. The repair of the resulting recurrent hernia is a daunting task because of already weakened tissues and obscured and distorted anatomy. The failure rate of these repairs using an open anterior approach may reach as high as 36%. Because of such a high failure rate, a number of investigators have focused on repairing these difficult recurrent hernias laparoscopically using a tension-free approach. Some of the earlier reports suggested a low recurrence rate of 0.5% to 5% when a laparoscopic approach was used to repair these hernias. The purpose of this study was to evaluate the efficacy of laparoscopic treatment for recurrent hernias in our institutions. METHODS: Between February 1991 and February 1995, 96 recurrent hernias were repaired in 85 patients (78 men and 7 women). There were 48 right, 26 left, and 11 bilateral hernias. The mean age of the patients was 59 years (range, 18-86 years); the mean height was 69 in. (range, 54-77 in.); and the mean weight was 176 pounds (range, 109-280 pounds). A total of 68 herniorrhaphies were performed using the transabdominal preperitoneal (TAPP) method: 19 using intraperitoneal on-lay mesh (IPOM) repair and 8 using the total extraperitoneal (TEP) method. The method of repair in one patient was not recorded. The mean operating time was 76 min (range, 47-172 min). Thirteen patients underwent additional procedures. RESULTS: Long-term follow-up was performed by questionnaire, examination, or both in 76 patients (85 hernias). Median follow-up time was 27 months (range, 2-56 months). There were four recurrences (2 in IPOM and 2 in TAPP). Three of these were repaired laparoscopically and one conventionally. There were 20 minor and 14 major complications and no mortality. One conversion occurred in the TAPP group. Mean postoperative stay was 1.4 days (range, 0-4 days). It was felt by 92% of the patients that their symptoms were completely relieved, whereas 4% of the patients continued to exhibit symptoms for which their hernia was repaired, and 3.6% failed to answer. As reported, 86% of the patients preferred their laparoscopic repair; 1% preferred the conventional repair; and 13% failed to reply. Afterward, 77% of the patients returned to normal activity, and 35% returned to vigorous activity within 4 weeks of surgery. Satisfaction with laparoscopic repair was expressed by 92% of the patients, whereas 8% either were dissatisfied or did not answer. In the end, 95% of the patients stated that they would recommend laparoscopic hernia surgery to their family and friends. CONCLUSIONS: These preliminary data show that laparoscopic repair of recurrent inguinal hernia is a safe alternative procedure with acceptable rates of recurrence and complications.     

Randomized controlled trial of laparoscopic transabdominal preperitoneal hernioplasty vs Shouldice repair

Background: There is a scarcity of data on long-term results after laparoscopic hernia repair. Herein we report on the outcome of a group of patients who were followed up for 5 years in a multicenter study on hernia repair. Methods: A total of 100 patients with 127 hernias were randomized to undergo either transabdominal preperitoneal (TAPP) or Shouldice hernia repair. Follow-up was by clinical examination and standardized questionnaire. Results: Of the 100 patients who underwent surgery, 84 were available for follow-up at 5 years. The TAPP procedure was less painful than the Shouldice repair, with fewer patients receiving narcotic analgesics. The median time to return to 100% activity was shorter in the laparoscopic group (21 days) than in the Shouldice group (40 days). Up to 60 months after the operation, the complication rate was lower in laparoscopically repaired hernias (19/66) than in the open group (25/61). There were two recurrences (3.9%) in the TAPP group and five in the Shouldice group (10.2%). Conclusion: The TAPP hernia repair yields comparable or better results than Shouldice herniorrhaphy in terms of postoperative pain, recovery, and recurrence rate.     

Scrotal hernias: a contraindication for an endoscopic procedure?

INTRODUCTION: Endoscopic repair was introduced for use with inguinal hernia therapy more than 10 years ago. The technique as well as the indications for this method are debated, however. As a borderline inguinal hernia situation, the scrotal hernia in particular evokes vehement objections to an endoscopic procedure because of the anticipated problems and complications in dissecting the extended hernia sac. The efficiency of the laparoscopic transabdominal preperitoneal (TAPP) technique in the treatment of scrotal hernia therefore is discussed in this article. METHODS: Laparoscopic hernia repair (TAPP) has been performed in our department since 1993. Data are collected by a prospective documentation of operative and follow-up results. For evaluation, a comparison of scrotal and normal hernia repair was performed. RESULTS: Between April 1993 and June 1998 the TAPP technique was used to treat 191 scrotal hernias, 42 (22%) of which were recurrent hernias. The median operating time for a normal inguinal hernia repair was 45 min, whereas scrotal hernias required a median of 65 min and irreducible scrotral hernias a median of 68.5 min. Major complications were observed in 1.6% of scrotal and 0.6% of normal inguinal hernia repairs. The most frequent scrotal hernia repair problem was the formation of a seroma, 10.5% of which had to be evacuated. During a follow-up period of 30 months, we found a total of two recurrences (1.05%). CONCLUSION: In scrotal hernia repair, TAPP is not associated with higher complication rates and can be performed with efficiency comparable with that in normal inguinal hernia repair.     

Repeated laparoscopic treatment of recurrent inguinal hernias after previous posterior repair

Background

The reported recurrence rates after laparoscopic inguinal hernia repair are 0–4 %. It is unclear which technique could best be offered to a patient with a recurrent hernia after a previous posterior repair. The purpose of this retrospective study was to determine the safety, feasibility, and reliability of a repeated laparoscopic repair (TAPP) for a recurrent hernia after a previous posterior inguinal hernia repair.

Methods

The study group contains 2,594 consecutive transabdominal inguinal hernia repairs (TAPP). Of these, 53 repairs were attempted in 51 patients for recurrent hernias after a previous posterior repair. During the follow-up period, patients were examined for recurrences and for presence of a port-site hernia. Pain was scored by the visual analogue pain scale (VAS).

Results

Fifty-one patients underwent a TAPP repair for a recurrent inguinal hernia after previous posterior hernia repair. Two patients presented a bilateral recurrent inguinal hernia. In two thirds of the patients, the recurrence was located caudally or medially from the previously placed mesh. Two attempted repairs had to be converted to an open technique due to severe adhesions. One intraoperative complication was encountered when the vas deferens was ligated during surgery due to adhesions of the previous placed mesh. Nine patients encountered an adverse event postoperatively, but none of them were serious events. No mesh infections were reported. The mean follow-up was 70 (range, 1–198) months. At follow-up, no recurrences were found at physical examination. Four patients developed a port-site hernia. Four patients had complaints of postoperative pain and were restricted in daily activities due to groin pain. The mean VAS score (scale 0–100), including the four patients with persistent pain, was 5.7 (range, 0–61).

Conclusions

It is concluded that repeated laparoscopic hernia repair (TAPP) is a definite repair for recurrent inguinal hernias. The procedure is feasible, safe, and reliable.     

The incidence and natural course of occult inguinal hernias during TAPP repair

Background

One of the proposed advantages of laparoscopic inguinal hernia repair is complimentary inspection of the contralateral side and possible detection of occult hernias. Incidence of occult contralateral hernias is as high as 50 %. The natural course of such occult defects is unknown and therefore operative rationale is lacking. This study was designed to analyze the incidence of occult contralateral inguinal hernias and its natural course.

Methods

A total of 1,681 patients were diagnosed preoperatively with unilateral inguinal hernia. None of these patients had complaints of the contralateral side preoperatively. All patients underwent laparoscopic inguinal hernia transabdominal preperitoneal (TAPP) repair. Operative details were analyzed retrospectively. Patients with occult contralateral defects were identified and tracked. Patients with an evident occult hernia received immediate repair. Patients with a smaller beginning or incipient hernia were followed.

Results

In 218 (13 %) patients, an occult hernia was found at the contralateral side during preoperative exploration. In 129 (8 %) patients, an occult true hernia was found. In 89 (5 %) patients, an occult incipient hernia was found. An incipient hernia was defined as a beginning hernia. All patients with an incipient hernia were followed. The mean follow-up was 112 (range 16–218) months. Twenty-eight (32 %) patients were lost to follow-up. In the 61 remaining patients, 13 (21 %) occult incipient hernias became symptomatic requiring repair. The mean time between primary repair and development of a symptomatic hernia on the contralateral side was 88 (range 24–210) months.

Conclusions

This study shows that the incidence of occult contralateral hernias is 13 % during TAPP repair of unilateral diagnosed inguinal hernias. In 5 % of the cases, the occult hernia consisted of a beginning hernia. Eventually, one of five will become symptomatic and require repair. These outcomes support immediate repair of occult defects, no matter its size.     

Laparoscopic trans-peritoneal hernioplasty (TAPP) for the acute management of strangulated inguino-crural hernias: a report of nine cases

Background Inguinal hernioplasty has always been one of the most commonly performed operations in clinical practice. In the last 15 years, thanks to the development of mini-invasive surgery, new video-endoscopic techniques for the treatment of inguinal hernia using trans-peritoneal (TAPP) and extraperitoneal (TEP) access have emerged. Both have a definite role in the treatment of bilateral and recurrent hernias, while the debate is still open about the treatment of primary mono-lateral hernias. In acute incarcerated hernia requiring an emergency operation, the endoscopic approach is uncommon and controversial, and even considered contraindicated. The aim of this publication is to verify the efficacy and the technical feasibility of TAPP operation by analyzing a consecutive series of patients operated on for incarcerated inguino-crural hernia associated with suspected visceral ischemic lesion in an emergency setting. Materials and methods From September 2004 to October 2005, 13 patients were operated on acutely for inguino-crural incarcerated hernia associated with suspected visceral ischemic damage. Four were excluded from the endoscopic treatment due to anesthesiologic contraindications or huge hernia dimensions. Nine patients were operated on using a trans-peritoneal approach (TAPP). Visceral mobilization and hernia reduction were obtained by incision and opening of the hernia ring. Visceral resection was performed in one case with intestinal ischemia following a prolonged observation time or “test time.” Results One case was associated with intestinal resection and incisional hernia repair, one with obturator hernia repair, and one with hepiployc appendix repair. None of the cases were converted to open technique, and no intra- or postoperative complications were recorded. Mean operative time was 72 min (35–180); mean hospital stay was 2.7 days (1–8). No recurrences were observed after a mean follow-up time of 18 months (8–24). Conclusions The TAPP procedure can be proposed for emergency treatment of inguino-crural incarcerated hernias, allowing not only hernia correction, but also visual control and the contestual treatment of the hernia content. TAPP is a more challenging procedure compared to the traditional open anterior approach and therefore requires an adequate laparoscopic training. Exclusion criteria are constituted by anesthesiologic contraindications or dimensional criteria of the hernia.     

Laparoscopic repair of recurrent groin hernia: results of a prospective study

Background  Recurrences continue to be seen after repair of inguinal hernias. The repair of these recurrent hernias is a more complex and demanding procedure, with a high re-recurrence rate. Definite advantage has been demonstrated with endoscopic repair of these hernias. Methods  The results for this prospective study from January 2003 to December 2006 were evaluated after laparoscopic repair of 65 recurrent hernias in 61 patients. The patients were followed up for 1 year. Longer follow-up evaluation was performed for the patients who underwent surgery in the initial 3 years. Results  In this study, 37 recurrent hernias were managed using the transabdominal preperitoneal technique (TAPP) technique and 28 using the totally extraperitoneal (TEP) technique. There was no conversion and no cases of postoperative wound infection. Of the 12 metachronous hernias repaired simultaneously, 3 were occult. Seroma developed in five patients. At a follow-up assessment after 1 year, one patient had groin pain, and there was one re-recurrence. A longer follow-up period with a mean of 35.11 months failed to show any new re-recurrence. Conclusions  Laparoscopic repair of recurrent inguinal hernia is safe and effective. The morbidity and recurrence rates for the procedure are as low as for laparoscopic repair of primary hernias. Laparoscopic repair should be the gold standard for these hernias.     

Totally extraperitoneal repair of obturator hernia

Background One distinct advantage of the 1aparoscopic inguinal hernia repair is the opportunity for clear visualization of the direct, indirect, femoral, and obturator spaces. The surgeon should routinely inspect all of them. Obturator hernia accounts for as few as 0.073% of all hernias, but the mortality rate when it is acutely incarcerated can be as high as 70%. There is only one previous report of a totally extraperitoneal repair for obturator hernia. Five such procedures are described.Methods A retrospective review was undertaken to evaluate one surgeons experience with the totally extraperitoneal repair of obturator hernia over a 4-year period. Four of five cases were completed, and the remaining case was converted to an open procedure.Results Three hernias were on the right side, and two on the left. One patient presented with an acutely incarcerated obturator hernia and underwent a small bowel resection for strangulated bowel within the obturator space. The other four hernias were found during totally extraperitoneal repair, and the patients were discharged home several hours later. There was one complication, a midline wound infection in the patient with strangulated bowel. It was treated with dressing changes. There were no other complications, and during a follow-up period of 3 to 48 months, there was no recurrence.Conclusions The laparoscopic totally extraperitoneal approach allows inspection and repair of direct, indirect, femoral, and obturator hernias. This study found this procedure to be feasible, safe, and highly effective for the diagnosis and repair of obturator hernias.     

Transabdominal Preperitoneal Repair for Obturator Hernia

Background

A laparoscopic surgical approach for obturator hernia (OH) repair is uncommon. The aim of the present study was to assess the effectiveness of laparoscopic transabdominal preperitoneal (TAPP) repair for OH.

Methods

From 2001 to May 2010, 659 patients with inguinal hernia underwent TAPP repair at in our institutes. Among these, the eight patients with OH were the subjects of this study.

Results

Three of the eight patients were diagnosed as having occult OH, and the other five were diagnosed preoperatively, by ultrasonography and/or computed tomography, as having strangulated OH. Bilateral OH was found in five patients (63%), and combined groin hernias, either unilaterally or bilaterally, were observed in seven patients (88%), all of whom had femoral hernia. Of the five patients with bowel obstruction at presentation, four were determined not to require resection after assessment of the intestinal viability by laparoscopy. There was one case of conversion to a two-stage hernia repair performed to avoid mesh contamination: addition of mini-laparotomy, followed by extraction of the gangrenous intestine for resection and anastomosis with simple peritoneal closure of the hernia defect in the first stage, and a Kugel hernia repair in the second stage. There was no incidence of postoperative morbidity, mortality, or recurrence.

Conclusions

Because TAPP allows assessment of not only the entire groin area bilaterally but also simultaneous assessment of the viability of the incarcerated intestine with a minimum abdominal wall defect, we believe that it is an adequate approach to the treatment of both occult and acutely incarcerated OH. Two-stage hernia repair is technically feasible in patients requiring resection of the incarcerated intestine.     

Total endoskopische präperitoneale Netzplastik bei primären und Rezidivleistenhernien Gibt es Unterschiede?

INTRODUCTION: Since 1994 we perform laparoscopic total extraperitoneal hernia repair (TEP) for primary and recurrent inguinal hernias at our institution. The aim of this study was to investigate and compare the results of TEP in primary inguinal hernias and recurrent inguinal hernias and to determine whether there are differences in patient data, complication rates and outcome between these two groups. METHODS: In a prospective trial 338 patients were analyzed who underwent 500 laparoscopic TEP repairs. In all, 431 TEP repairs were performed for primary inguinal hernias, and 69 for recurrent inguinal hernias. For data acquisition the SALTC study protocol was used. All patients were clinically examined 3 and 12 months after the operation. RESULTS: The mean operation time was 67.3 min for TEP repair of primary hernias and 68.1 min for TEP repair of recurrent hernias, respectively. The conversion rate to an open procedure was 0%. Conversion from TEP into TAPP was required in 0.5% of patients with primary inguinal hernias and 1.4% of patients with recurrent inguinal hernias. As the sole difference between the two groups the intraoperative complication rate could be identified. In the TEP repair group of recurrent inguinal hernias a higher incidence of injury to the peritoneum and a higher occurrence of bleeding from the epigastric vessels was found (P = 0.03). The postoperative complication rate was identical in the two groups, amounting to 5.1% and 5.7%, respectively. No differences were found in the 1 year follow-up between the two groups. The 1-year recurrence rate was 0.5% for primary hernias. However, in the group of recurrent hernias there have been no recurrences to date. CONCLUSIONS: The use of laparoscopic TEP repair has proven to be a safe and effective treatment in patients with primary and recurrent inguinal hernias. Because of scar tissue with possible adhesions a higher intraoperative complication rate was observed in the TEP repair of recurrent hernias than in TEP repair of primary inguinal hernias. However, no single recurrence was observed in the TEP repair group of recurrent hernias. In our opinion TEP is the optimal hernia repair for recurrent and bilateral inguinal hernias.

Totally extraperitoneal (TEP) hernia repair after radical prostatectomy or previous lower abdominal surgery

Background Many practicing surgeons claim that hernias after previous lower abdominal surgery should be treated by transabdominal preperitoneal repair (TAPP). Moreover, previous radical prostatectomy contraindicates the laparoscopic approach for hernia repair. This prospective study was designed to examine the feasibility and to evaluate the surgical outcome of laparoscopic totally extraperitoneal (TEP) hernia repair in patients who had undergone previous lower abdominal surgery or radical prostatectomy, and to compare this group to all patients who underwent laparoscopic TEP without previous surgery during the study period. Methods Patients undergoing elective inguinal hernia repair, by one staff surgeon, in the Department of Abdominal Surgery at the Institute of Laparoscopic Surgery (ILS, Bordeaux) between September 2003 and December 2004 were prospectively enrolled to this study. Three groups were defined—patients with previous radical prostatectomy, patients with previous lower abdominal surgery, and patients without previous surgery—and their data were analyzed and compared. Results A total of 256 laparoscopic inguinal hernia repairs were performed in 202 patients. Of these, 148 patients had unilateral hernia (143 right and 113 left) and 54 patients had bilateral hernias. There were 166 male patients and 36 female patients with a mean age of 61 ± 16 years. Of these, 10 patients had inguinal hernia after prostatectomy and 15 patients had inguinal hernia after previous lower abdominal surgery. The mean operative time was significantly longer in the patients with previous prostatectomy than in the two other groups. Two patients after prostatectomy were converted to TAPP due to surgical difficulties. There were no major intraoperative complications in all patients except for three cases of bleeding arising from the inferior epigastric artery: two in the postprostatectomy group and one in a patient without previous surgery. Both ambulation and hospital stay were similar for all groups. Only one patient without previous surgery had postoperative bleeding and was reoperated on several hours after the hernia repair. During the follow-up period of 8 ± 4 months, there was no recurrence of the hernia in any group. Conclusions Laparoscopic TEP for inguinal hernia repair in patients after previous low abdominal surgery has good results, similar to those in patients without previous surgery. Despite a longer operative time, TEP repairs can be performed efficiently and safely in patients after prostatectomy by skilled and experienced laparoscopic surgeons.     

Patient satisfaction after laparoscopic and conventional day case inguinal hernia repair

Comparison of patient satisfaction after laparoscopic and conventional day case inguinal hernia repair. The post-operative course of 60 patients subjected to laparoscopic hernia repair (TAPP) and conventional anterior hernia repair (Griffith) under general anaesthesia as day case procedures was analysed. Both groups (TAPP, n=30; Griffith, n=30) were comparable for age and gender. The operating time, success rate of ambulatory surgery, readmissions and complications were assessed. After 6 months (range 3–10) post-operative pain and nausea, consumption of analgesics/anti-emetics, convalescence and adequacy of the patient information were recorded by a telephonic questionnaire. The patients were asked also if they would choose again a day case procedure for hernia repair. In the TAPP group, 28 out of 30 operations succeeded in ambulatory surgery; one patient was admitted because of nausea and another because of the late time of operation. In the Griffith group all operations succeeded as a day case procedure. In the TAPP group patients experienced less pain (P=0.05), but more nausea (P<0.05), they also needed fewer days bedrest (P<0.05) and felt fully recovered sooner. A total of 90% of both groups would choose a day case procedure again. In conclusion, laparoscopic inguinal hernia repair under general anaesthesia can very well be performed as a day case procedure. After laparoscopic hernia repair patients experienced less pain (statistically non significant) and had an earlier recovery, but they had more nausea than after conventional repair.     

Day-case laparoscopic hernia repair in a single unit

BACKGROUND: Laparoscopic groin hernia repair has been shown to be a safe, well-tolerated procedure. Here, we report a series of patients who underwent laparoscopic transabdominal preperitoneal (TAPP) mesh repair as day cases. RESULTS: We performed 984 repairs on 769 patients, 218 had bilateral repairs. Mean operating time was 25 min for unilateral and 38 min for bilateral repairs. Three were converted, and 39 required admission. Five were readmitted more than 48 h postoperatively. Three required reoperation for small bowel obstruction from herniation through a peritoneal defect. Only 57% of patients required analgesia for a mean of 1.9 days after discharge. Recovery times were similar for unilateral and bilateral herniae. Eight hernias have recurred to date. CONCLUSIONS: Laparoscopic hernia repair is suitable for day-case surgery for unilateral, bilateral, and recurrent herniae. TAPP repair allows inspection of the contralateral groin, with repair of defects as necessary.

Prospective randomized trial of laparoscopic (transabdominal preperitoneal) vs open (mesh) repair for bilateral and recurrent inguinal hernia

Background: Laparoscopic hernia repair excites controversy because its benefits are debatable and critics claim it is attended by serious complications. The one group of patients in whom benefits may outweigh the perceived disadvantages are those with bilateral or recurrent inguinal hernias. Method: One hundred twenty patients with bilateral or recurrent hernias were randomized to either laparoscopic transabdominal preperitoneal (TAPP) or open mesh repair. Patients completed a well-being questionnaire prior to and following surgery together with a visual analog pain score. Patients were followed up clinically at 1 and 3 months and thereafter by their general practitioner. Results: Age and sex distribution was similar in the two groups. Laparoscopic TAPP hernia was quicker (40 vs 55 min; p < 0.001), less painful (visual analog pain score, 2.8 vs 4.3; p = 0.003) and allowed earlier return to work (11 vs 42 days; p < 0.001) compared to open mesh repair. Conclusion: This trial demonstrates that laparoscopic hernia repair via the TAPP route offers significant benefit to patients undergoing bilateral or recurrent inguinal hernia repair.
