Prospective non-randomized comparison of open versus laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair under different anesthetic methods

Purpose

To compare prospectively open vs. laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair performed under different anesthetic methods.

Methods

A total of 175 patients scheduled for unilateral inguinal hernia repair were assigned to one of the following groups: (i) open repair under local anesthesia, (ii) open repair under regional anesthesia, (iii) open repair under general anesthesia, and (iv) TAPP under regional anesthesia. Immediate postoperative pain was the main outcome measured. Short- and long-term complications and the degree of patient satisfaction were also assessed.

Results

Transabdominal preperitoneal repair under regional anesthesia yielded the lowest pain scores, whereas open repair under general anesthesia yielded the highest pain scores (P < 0.05). Open repair under local or general anesthesia had a lower urinary retention incidence than the spinal groups (P < 0.05). Chronic pain incidence was lower for the TAPP group (P 0.003). There were no differences in other short- and long-term complications.

Conclusion

Transabdominal preperitoneal repair under spinal anesthesia proved superior to open repair performed under different types of anesthesia in terms of immediate (24-h) postoperative pain. The method of anesthesia might have contributed more to this favorable outcome than the surgical technique itself, but at the cost of a high urinary retention incidence. The incidence of chronic pain was lower after TAPP repair.     

Laparoscopic inguinal hernioplasty after robot-assisted laparoscopic radical prostatectomy

Purpose

To evaluate the efficacy and safety of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RALP).

Methods

From July 2014 to December 2016, TAPP inguinal hernia repair was conducted in 40 consecutive patients who had previously undergone RALP. Their data were retrospectively analyzed as an uncontrolled case series.

Results

The mean operation time in patients who had previously undergone RALP was 99.5 ± 38.0 min. The intraoperative blood loss volume was small, and the duration of hospitalization was 2.0 ± 0.5 days. No intraoperative complications or major postoperative complications occurred. During the average 11.2-month follow-up period, no patients who had previously undergone prostatectomy developed recurrence.

Conclusions

Laparoscopic TAPP inguinal hernia repair after RALP was safe and effective. TAPP inguinal hernia repair may be a valuable alternative to open hernioplasty.

     

Tumescent TAPP: laparoscopic inguinal hernia repair after the preperitoneal tumescent injection of diluted lidocaine and epinephrine saline solution and carbon dioxide gas

Purpose

Laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP) is technically difficult and not infrequently followed by postoperative complications and pain, especially when performed by inexperienced surgeons. To simplify TAPP and reduce postoperative pain, we devised a novel procedure whereby TAPP is carried out after the inguinal preperitoneal infiltration of diluted lidocaine and epinephrine saline solution and carbon dioxide gas (tumescent TAPP). This report introduces the concept of tumescent TAPP and summarizes its operative results.

Methods

About 120 ml of diluted lidocaine and epinephrine solution and 60 ml of CO₂ gas were infiltrated into the inguinal preperitoneal space through a transabdominal needle before TAPP. Tumescent TAPP was performed for 400 patients (355 men, 45 women; mean age, 63.2 years).

Results

Using tumescent TAPP, we found it easier to confirm the inguinal anatomy and dissect the preperitoneal layer and inguinal floor, with less bleeding. The mean operation time was 101.9 min and there were few perioperative complications and minimal pain.

Conclusions

Tumescent TAPP makes conventional TAPP easier and safer; however, this procedure should be verified by a comparative study with conventional TAPP.

     

Comparison of hospital costs and length of stay associated with open-mesh, totally extraperitoneal inguinal hernia repair, and transabdominal preperitoneal inguinal hernia repair: An analysis of observational data using propensity score matching

Background

Laparoscopic inguinal hernia surgery is increasingly seen as the superior technique in hernia repair. Compared to open-mesh hernia repair, laparoscopic approaches are often reported to be more cost-effective but incur higher costs for the provider. The objective of this study was to analyze the effect of transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) repair of nonincarcerated inguinal hernias in men on hospital costs and length of stay (LoS).

Methods

We used routine administrative, highly standardized, patient-level cost data from 15 German hospitals participating in the national cost data study. We compared TEP, TAPP, and open-mesh repair. We conducted propensity score matching to account for baseline differences between treatment groups and subsequently estimated the treatment effect on costs and LoS.

Results

Total costs for both TEP and TAPP surgery were significantly lower than those for open-mesh repair (p < 0.0001 and p < 0.05, respectively). TEP repair also had a slight but nonsignificant advantage in total costs compared to TAPP repair, while TAPP surgery was associated with a significantly shorter LoS than TEP (p < 0.001).

Conclusion

Results suggest that laparoscopic approaches in hernia repair are not necessarily associated with higher hospital resource consumption than open-mesh repair.     

TAPP or TEP? Population-Based Analysis of Prospective Data on 4,552 Patients Undergoing Endoscopic Inguinal Hernia Repair

Background

Whether total extraperitoneal inguinal hernia repair (TEP) is associated with worse outcomes than transabdominal preperitoneal inguinal hernia repair (TAPP) continues to be a matter of debate. The objective of this large cohort study is to compare outcomes between patients undergoing TEP or TAPP.

Methods

Based on prospective data of the Swiss association of laparoscopic and thoracoscopic surgery, all patients undergoing unilateral TEP or TAPP between 1995 and 2006 were included. The following outcomes were compared: conversion rates, intraoperative and postoperative complications, duration of operation.

Results

Data on 4,552 patients undergoing TEP (n?=?3,457) and TAPP (n?=?1,095) were collected prospectively. Average age and American Society of Anesthesiologists score were similar in the two groups. Patients undergoing TEP had a significantly higher rate of intraoperative complications (TEP 1.9?% vs. TAPP 0.9?%, p?=?0.029) and surgical postoperative complications (TEP: 2.3?% vs. TAPP: 0.8?%, p?=?0.003). The postoperative length of stay was longer for patients undergoing TAPP (2.9 vs. 2.3?days, p?=?0.002), whereas the duration of the operation was longer for TEP (66.6 vs. 59.0?min, p?<?0.001) and the conversion rate was higher (TEP 1.0?% vs. TAPP 0.2?%, p?=?0.011).

Conclusions

This study is one of the first population-based analyses comparing TEP and TAPP in a prospective cohort of more than 4,500 patients. Intraoperative and surgical postoperative complications were significantly higher in patients undergoing TEP. TEP is also associated with longer operating times and higher conversion rates. Therefore, on a population-based level, the TAPP technique appears to be superior to the TEP repair in patients undergoing unilateral inguinal hernia repair.     

Which is the best laparoscopic approach for inguinal hernia repair: TEP or TAPP? A systematic review of the literature with a network meta-analysis

Background

Totally extraperitoneal (TEP) repair and transabdominal preperitoneal (TAPP) repair are the most used laparoscopic techniques for inguinal hernia treatment. However, many studies have shown that laparoscopic hernia repair compared with open hernia repair (OHR) may offer less pain and shorter convalescence. Few studies compared the clinical efficacy between TEP and TAPP technique. The purpose of this study is to provide a comparison between TEP and TAPP for inguinal hernia repair to show the best approach.

Methods

We performed an indirect comparison between TEP and TAPP techniques by considering only randomized, controlled trials comparing TEP with OHR and TAPP with OHR in a network meta-analysis. We considered the following outcomes: operative time, postoperative complications, hospital stay, postoperative pain, time to return to work, and recurrences.

Results

The two techniques improved some short outcomes (such as time to return to work) with respect to OHR. In the network meta-analysis, TEP and TAPP were equivalent for operative time, postoperative complications, postoperative pain, time to return to work, and recurrences, whereas TAPP was associated with a slightly longer hospital stay compared with TEP.

Conclusions

TEP and TAPP improved clinical outcomes compared with OHR, but the network meta-analysis showed that TEP and TAPP efficacy is equivalent. TAPP was associated with a slightly longer hospital stay compared with TEP.     

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.     

Low recurrence rate and low chronic pain associated with inguinal hernia repair by laparoscopic placement of Parietex ProGrip™ mesh: clinical outcomes of 220 hernias with mean follow-up at 23 months

Introduction

The aim of this study was to demonstrate the safety and the efficacy of the self-gripping Parietex ProGrip? mesh (Sofradim Production, Trévoux, France) used with the laparoscopic approach for inguinal hernia repair. The incidence of chronic pain, post-operative complications, patient satisfaction and hernia recurrence at follow-up after 12 months was evaluated.

Methods

Data were collected retrospectively from patient files and were analyzed for 169 male and female patients with 220 primary inguinal hernias. All patients included had undergone surgical repair for inguinal hernia by the laparoscopic transabdominal preperitoneal approach using Parietex ProGrip? meshes performed in the same clinical center in Germany. Pre-, per- and post-operative data were collected, and a follow-up after 12 months was performed prospectively. Complications, pain scored on a 0–10 numeric rating scale (NRS), patient satisfaction and hernia recurrence were assessed.

Results

The only complications were minor and were post-operative: hematoma/seroma (3 cases), secondary hemorrhage through the trocar’s site (2 cases), hematuria, emphysema in the inguinal regions (both sides) and swelling above the genital organs (1 case for each). At mean follow-up at 22.8 months, there were only 3 reports of hernia recurrence: 1.4 % of the hernias. Most patients (95.9 %) were satisfied or very satisfied with their hernia repair with only 1.2 % reporting severe pain (NRS score 7–10) and 3.6 % reported mild pain.

Conclusion

This study demonstrates that in experienced hands, inguinal hernia repair surgery performed by laparoscopic transabdominal preperitoneal hernioplasty using Parietex ProGrip? self-gripping meshes is rapid, efficient and safe with low pain and low hernia recurrence rate.     

A comparison of outcomes between open and laparoscopic surgical repair of recurrent inguinal hernias

Background

Inguinal hernia recurrence after surgical repair is a major concern. The authors report their experience with open and laparoscopic repair of recurrent inguinal hernias.

Methods

After institutional review board approval, a retrospective review was performed with the charts of 197 patients who had undergone surgical repair of recurrent inguinal hernias from January 2000 through August 2009, and the data for 172 patients who met the inclusion criteria were analyzed. Surgical variables and clinical outcomes were compared using Student??s t test, the Mann?CWhitney U test, chi-square, and Fisher??s exact test as appropriate.

Results

The review showed that 172 patients had undergone either open mesh repair (n?=?61) or laparoscopic mesh repair (n?=?111) for recurrent inguinal hernias. Postoperative complications were experienced by 8 patients in the open group and 17 patients in laparoscopic group (p?=?0.70). Five patients (8.2%) in the open group and four patients (3.6%) in the laparoscopic group had re-recurrent inguinal hernias (p?=?0.28). Four patients in the open group (9.5%) and no patients in the laparoscopic group had recurrence during long-term follow-up evaluation (p?=?0.046). In the laparoscopic group, 76 patients (68.5%) underwent total extraperitoneal (TEP) repair, and 35 patients (31.5%) had transabdominal preperitoneal (TAPP) repair. Postoperative complications were experienced by 13 patients in the TEP group and 4 patients in the TAPP group (p?=?0.44). Two patients (2.6%) in the TEP group and two patients (5.7%) in the TAPP group had re-recurrent inguinal hernias (p?=?0.59).

Conclusions

This retrospective review showed no statistical difference in the re-recurrence rate between the two techniques during short-term follow-up evaluation. However, the laparoscopic technique had a significantly lower re-recurrence rate than the open technique during long-term follow-up evaluation. Both procedures were comparable in terms of intra- and postoperative complications. Among laparoscopic techniques, TEP and TAPP repair are acceptable methods for the repair of recurrent inguinal hernia. A multicenter prospective randomized control trial is needed to confirm the findings of this study.     

Health-related quality of life after TAPP repair for the sportsmen’s groin

Background

Sportsmen’s groin (SG) is a clinical diagnosis of chronic, painful musculotendinous injury to the medial inguinal floor in the absence of a groin hernia. Long-term results for laparoscopic inguinal hernia repair, especially data on health-related quality of life (HRQOL), are scant and there are no available data whatsoever on HRQOL after SG. The main goal of this study was to compare postoperative QOL data in the long term after transabdominal preperitoneal hernioplasty (TAPP) in groin hernia and SG patients with QOL data of a normal population.

Methods

This study included all patients (n = 559) who underwent TAPP repair between 2000 and 2005. Forty seven patients (8.4 %) were operated on for SG. We sent out the Short Form 36 Health Survey (SF-36) questionnaire for QOL evaluation. QOL data were compared with data from an age- and sex-matched normal population.

Results

Ultimately, 383 completed questionnaires were available for evaluation (69 % response rate). The mean follow-up time was 94 ± 20 months. In the SG group there were statistically significant differences in three subscales of the SF-36 and the mental component summary measure, showing better results for the SG group compared to the sex- and age-matched normal group data. There were no statistically significant differences between groin hernia patients and the sex- and age-matched normal population.

Conclusion

TAPP repair for SG as well as groin hernia results in good HRQOL in the long term. Results for SG patients are comparable with QOL data of a normal population or even better.     

Laparoscopic transabdominal preperitoneal inguinal hernia repair using needlescopic instruments: a 15-year, single-center experience in 317 patients

Background

Laparoscopic inguinal hernia repair is associated with a decrease in postoperative pain, shortened hospital stay, earlier return to normal activity, and decrease in chronic pain. Moreover, laparoscopic surgery performed with needlescopic instruments has more advantages than conventional laparoscopic surgery. However, there are few reports of large-scale laparoscopic transabdominal preperitoneal inguinal hernia repair using needlescopic instruments (nTAPP). This report reviews our experiences with 352 nTAPP in 317 patients during the 15-year period from April 1996 to April 2011.

Methods

We performed nTAPP as the method of choice in 88.5% of all patients presenting with inguinal hernia. To perform the nTAPP, 3-mm instruments were used. A 5-mm laparoscope was inserted from the umbilicus, and surgical instruments were inserted through 5- and 3-mm trocars. After reduction of the hernia sac and dissection of the preperitoneal space, we placed polyester mesh or polypropylene soft mesh with staple fixation. The peritoneum was closed with 3–0 silk interrupted sutures.

Results

The mean operative time was 102.9?min for unilateral hernias and 155.8?min for bilateral hernias. There was no conversion to open repair. Forty-three patients (13.6%) used postoperative analgesics, and the mean frequency of use was 0.5 times. Regarding intraoperative complications, we observed one bladder injury, but no bowel injuries or major vessel injuries. Postoperative complications occurred in 32 patients (10.1%). One patient with a retained lipoma required reoperation. There was no incidence of chronic pain or mesh infection. The operative time for experienced surgeons (≥20 repairs) was significantly shorter than that of inexperienced surgeons (<20 repairs; P?Conclusions The nTAPP was a safe and useful technique for inguinal hernia repair. Large prospective, randomized controlled trials will be required to establish the benefit of nTAPP.     

The Incidence and Success of Treatment for Severe Chronic Groin Pain After Open, Transabdominal Preperitoneal, and Totally Extraperitoneal Hernia Repair

Background

Chronic groin pain (CGP) is a significant cause of postoperative morbidity after inguinal hernia repair. Open, transabdominal preperitoneal (TAPP), and totally extraperitoneal (TEP) repair are all commonly performed methods of herniorrhaphy. The aim of this study was to compare the frequency of attendance at a chronic pain clinic (CPC) for CGP after open, TAPP or TEP repair.

Methods

A retrospective review of all inguinal hernia repairs between January 1997 and December 2006 identified patients attending the CPC for CGP post-herniorrhaphy. In this study CGP post-herniorrhaphy was defined as pain that limited daily activities despite simple analgesia thereby requiring referral to the specialist CPC following surgical review.

Results

A total of 8513 patients underwent 9607 inguinal hernia repairs; 6497 (75.5%) were open, 1916 (22.3%) were TAPP, and 198 (2.3%) were TEP. Of these, 46 (0.71%) open, 22 (1.15%) TAPP, and 6 (3.03%) TEP repairs required attendance at CPC. A statistically significant difference in frequency of CPC attendance following laparoscopic versus open (P = 0.008), TEP versus open (P ≤ 0.001), and TEP versus TAPP repair (P = 0.027) was observed. After an average of 1 year, 69% of patients were discharged symptom-free from the CPC. In 16%, CGP resolved prior to CPC attendance.

Conclusions

In contrast to previous reports, laparoscopic hernia repair is associated with a greater frequency of attendance at CPC than open repair, a finding that merits further investigation. Of those requiring treatment, the majority were discharged pain-free after an average of 1 year.     

Patient-perspective quality of life after laparoscopic and open hernia repair: a controlled randomized trial

Background

Laparoscopic hernia repair accounts for 10% of all hernia surgery. Potential benefits include reduction in postoperative pain, rapid recovery, lower recurrence rate, and fewer complications. The outcomes of health-related quality of life and patient perspective after hernia repair are our aim.

Methods

Consecutive patients treated for unilateral uncomplicated groin hernia were enrolled after evaluation for inclusion. Participants were randomly distributed to receive either laparoscopic transabdominal preperitoneal repair (TAPP) (group I) or Lichtenstein repair (group II). Operative and postoperative complications, operative time, hospital stay, and late complications were assessed early postoperatively, at 4?weeks, and every 6?months thereafter. Quality of life was assessed using Short Form-36 questionnaire in the first visit (after 4?weeks).

Results

One hundred and eighty-five patients of unilateral uncomplicated groin hernia were included; 88 patients (group I) were treated by TAPP, and 97 patients were treated by Lichtenstein repair (group II) with median follow-up of 17.9?months. Mean hospital stay, mean operative time, operative and postoperative complications were similar in the two groups. Quality of life showed better and significant outcomes in group I for physical function (p?≤?0.001), role physical (p?≤?0.011), bodily pain (p?≤?0.017), general health (p?≤?0.047), and total physical health (p?≤?0.008). However, mental health showed no statistical significance in its four scales, but with better outcomes in group I. Total quality outcomes showed significantly better outcomes in group I (p?≤?0.031).

Conclusions

TAPP hernia repair technique is a safe technique with low complication rate, less postoperative body pain, and better quality-of-life outcomes compared with open technique, being well accepted from the patient’s perspective for quality of life.     

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.     

Unsuspected femoral hernia in patients with a preoperative diagnosis of recurrent inguinal hernia

Purpose

Small femoral hernias may be difficult to diagnose by physical examination and are sometimes identified unexpectedly by laparoscopy. The aim of this study was to examine the incidence of unsuspected femoral hernia discovered during laparoscopic inguinal hernia repair in two well-defined patient groups.

Methods

Patients undergoing laparoscopic transabdominal preperitoneal inguinal hernia repair from April 2000 until December 2009 (n?=?561) were prospectively registered including data on previous hernia operations and identified type of hernia during surgery. We included patients whose preoperative diagnosis was either bilateral primary inguinal hernia (Primary Group) or recurrent inguinal hernia (Recurrent Group).

Results

Four hundred and sixty-one (82.2?%) patients were included in the study, of whom 211 (45.8?%) was in the Primary Group and 250 (54.2?%) in the Recurrent Group. The incidence of unsuspected femoral hernia in the Recurrent Group [23/250, 9.2?% (95?% CI 5.9–13.5?%)] was significantly higher than in the Primary Group [8/211, 3.8?% (95?% CI 1.7–7.3?%)], p?=?0.02. Furthermore, 38.1?% of women operated on for a recurrent inguinal hernia, presented with an unsuspected femoral hernia at surgery as opposed to 6.6?% of the men, p?=?0.003.

Conclusion

Unsuspected femoral hernias are more prevalent in patients with recurrent hernia than in patients with primary hernia in the inguinal region. Femoral hernias may be unrecognized at the primary inguinal hernia operation, or the previous inguinal hernia operation may facilitate the formation of a femoral hernia. Unsuspected femoral hernias are especially frequent in women with recurrent inguinal hernia. In women with a groin hernia, a femoral hernia should always be excluded by laparoscopy or by open exploration of the preperitoneal space.     

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.     

Spigelian hernia repair as a day-case procedure

Purpose

Only a few series of patients with a spigelian hernia managed on an outpatient basis have been reported in the literature. The aim of this prospective study was to evaluate the results of the elective spigelian hernia repair as an ambulatory procedure.

Methods

From June 2007 to June 2010, 8 patients with 9 spigelian hernias were electively operated on under local anesthesia as a day case. Four patients had unilateral spigelian hernia, 1 had spigelian and inguinal on the same side, 1 had spigelian and epigastric, 1 had spigelian and umbilical, and 1 patient had bilateral spigelian and umbilical hernia. Spigelian hernia was managed by the “open preperitoneal flat mesh technique.” In patients with several ventral hernias at different sites, “the open preperitoneal flat mesh technique” was performed using one separate flat mesh for each of the hernias; for the patient with inguinal hernia, the Lichtenstein procedure was performed in addition.

Results

No complications and recurrences were recorded during a mean follow-up of 23.5 months (range: 11–35).

Conclusion

The elective spigelian hernia can be successfully repaired under local anesthesia as a day-case procedure. The “open preperitoneal flat mesh technique” provides excellent results under these conditions.     

Laparoscopic transabdominal preperitoneal repair of inguinal hernia under spinal anesthesia: a pilot study

Background

The laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is an evolving technique associated with the well-known advantages of a minimally invasive approach. However, general anesthesia is routinely required for the procedure. Based on our previous experience in regional anesthesia for laparoscopic procedures, we designed a pilot study to assess the feasibility and safety of performing laparoscopic TAPP repair under spinal anesthesia.

Methods

Forty-five American Society of Anesthesiologists I or II patients with a total of 50 inguinal hernias underwent TAPP repair under spinal anesthesia, using a low-pressure CO₂ pneumoperitoneum. Five patients had bilateral hernias, and 4 patients had recurrent hernias. Thirty hernias were indirect and the remaining direct. Intraoperative incidents, postoperative pain complications, and recovery in general as well as patient satisfaction at the follow-up examination were prospectively recorded.

Results

There was 1 conversion from spinal to general anesthesia and 2 conversions from laparoscopic to the open procedure at a median operative time of 50 minutes (range 30-130). Ten patients complained of shoulder pain during the procedure, and 6 patients suffered hypotension intraoperatively. The median pain score (visual analog scale) was 1 (0-5) at 4 hours after the completion of the procedure, 1.5 (0-6) at 8 hours, and 1.5 (0-5) at 24 hours, and the median hospital stay was 1 day (range 1-2). Sixteen patients had urinary retention requiring instant catheterization. At a median follow-up of 20 months (range 10 months-28 months), no recurrence was detected.

Conclusions

TAPP repair is feasible and safe under spinal anesthesia. However, it seems to be associated with a high incidence of urinary retention. Further studies are required to validate this technique.     

TAPP or TEP for Recurrent Inguinal Hernia? Population-Based Analysis of Prospective Data on 1309 Patients Undergoing Endoscopic Repair for Recurrent Inguinal Hernia

Background

Whether total extraperitoneal inguinal hernia repair (TEP) is associated with worse outcomes compared to transabdominal preperitoneal inguinal hernia repair (TAPP) for the treatment of recurrent inguinal hernia continues to be a matter of debate. The objective of this large cohort study is to compare complications, conversion rates and postoperative length of hospital stay between patients undergoing TEP or TAPP for unilateral recurrent inguinal hernia repair.

Method

Based on prospective data of the Swiss Association of Laparoscopic and Thoracoscopic Surgery, all patients who underwent elective TEP or TAPP for unilateral recurrent inguinal hernia between 1995 and 2006 were included. The following outcomes were compared: conversion rates, intraoperative complications, surgical postoperative complications and duration of operation.

Results

Data on 1309 patients undergoing TEP (n = 1022) and TAPP (n = 287) for recurrent inguinal hernia were prospectively collected. Average age, BMI and ASA score were similar in both groups. Patients undergoing TEP had a significantly increased rate of intraoperative complications (TEP 6.3 % vs. TAPP 2.8 %, p = 0.0225). Duration of operation was longer for patients undergoing TEP (TEP 80.3 vs. TAPP 73.0 min, p < 0.0023) while postoperative length of hospital stay was longer for patients undergoing TAPP (TEP 2.6 vs. TAPP 3.1 day, p = 0.0145). Surgical postoperative complications (TEP 3.52 % vs. TAPP 2.09 %, p = 0.2239), general postoperative complications (TEP 1.47 % vs. TAPP 0.7 %, p = 0.3081) and conversion rates (TEP 2.15 % vs. TAPP 1.39 %, p = 0.4155) were not significantly different.

Conclusion

This study is the first population-based analysis comparing outcomes of patients with recurrent inguinal hernia undergoing TEP versus TAPP in a prospective cohort of over 1300 patients. Intraoperative complications were significantly higher in patients undergoing TEP. The TEP technique was associated with longer operating times, but a shorter postoperative length of hospital stay. Nonetheless, the absolute outcome differences are small and thus, on a population-based level, both techniques appear to be safe and effective for patients undergoing endoscopic repair for unilateral recurrent inguinal hernia.

     

Preperitoneal herniation and bowel obstruction post laparoscopic inguinal hernia repair: case report and review of the literature

Laparoscopic inguinal hernia repairs, both transabdominal preperitoneal (TAPP) and total extraperitoneal (TEP), are associated with peritoneal defects or tears. Nonclosure of the tears can lead to bowel obstruction. I present a case of an early (48 h) bowel obstruction related to a peritoneal defect post TAPP inguinal hernia repair. The literature on peritoneal closure and bowel obstruction related to laparoscopic inguinal hernia repair is reviewed as well as options for repairing defects.
