Comparison of peritoneal closure techniques in laparoscopic transabdominal preperitoneal inguinal hernia repair: a prospective randomized study

Closure of the Peritoneum in Laparoscopic Transabdominal Preperitoneal Inguinal Hernia Repair (TAPP) With Cyanoacrylate Glue in a Microdroplet Device: A Single Surgeon Prospective Comparison vs. Barbed Suture

Purpose

To describe and compare a peritoneal closure technique using cyanoacrylate glue (Glubran 2®, GEM, Cardiolink SL) with a microdroplet device (Glutack®, GEM, Cardiolink SL) in laparoscopic transabdominal preperitoneal repair (TAPP) of inguinal hernia with the routinely used barbed suture peritoneal closure (V-Lock 3.0, Covidien France).

Materials and methods

From January to August 2022, 60 patients undergoing TAPP repair for uni- or bilateral inguinal hernia were randomized into one of two groups. One using as mesh fixation and peritoneal closure the Glutack® device with Glubran 2® cyanoacrylate glue (Glu-close group) and the other using mesh fixation with cyanoacrylate and peritoneal closure with V-lock 3.0 (Sut-close group), with a follow-up of 12 months. Demographic variables, operative time, peritoneal closure time, main surgical findings and main intra- and postoperative complications were analyzed prospectively.

Results

63 patients were included with no losses to follow-up. The mean operative time was 34 min (range 58.25) for the glu-close group and 40 (range 64.25) for the sut-close group, with no conversion (0%) for either group. The mean flap closure time was 1.18 min (SD 24 0.19) for the glu-close group and 3.24 min (SD 0.78) for the sut-close group, with statistically significant differences (p < 0.001). The intraoperative complication rate was 0 for the glu-close group and 0 for the sut-close group, with no significant difference. The median hospital stay was 0.8 days (range, 0-1) for both groups. The median duration of follow-up was 12 months and none had hernia recurrence. The postoperative VAS score at the first and second check-up at 1 month and 3 months was 2.83 (SD 1.341) and 0.60 (SD 0.621) in the sut-close group and 1.03 (0.984) and 0.24 (SD 0.435) in the glue-close group, with significant differences (p < 0.001 and p < 0.012).

Conclusion

The data demonstrated by the study are that the glue can be used safely to close the peritoneum and that the method provides a small, statistically significant but not clinically relevant reduction in the time to close the peritoneal flap, as well as in postoperative pain after surgery in short and medium term.

Comparison of Robotic, Laparoscopic, and Open Unilateral Repair of Non-recurrent Inguinal Hernia

BACKGROUND

There is a paucity of data comparing open, robotic, and laparoscopic approaches on unilateral, non-recurrent inguinal hernias. Our study presents a large, retrospective triple-arm outcome analysis between robotic, laparoscopic, and open unilateral, non-recurrent inguinal hernia repairs at a single institution.

METHODS

706 patients who underwent elective, non-recurrent inguinal hernia repair performed by 8 general surgeons at a single institution from 2016 to 2019 were reviewed retrospectively. Patient baseline characteristics, operative times, resident involvement, and postoperative outcomes were analyzed for all repair types. A cost analysis of the different procedures was performed.

RESULTS

There were 305 laparoscopic repairs, 207 robotic repairs, and 194 open repairs. Open and laparoscopic repairs were performed on patients who were older (p =< .001) and with a higher Charlson Comorbidity Index (p =< .001). Patient BMI was higher in minimally invasive repair than open repair (P = .021). There were no significant differences in complication rates on pairwise analysis. Robotic and open repairs had significantly longer operative times than laparoscopic repairs (P < .001). There was less resident involvement in robotic repair than with the other approaches (P < .001). Resident involvement was associated with shorter OR times (P = .001) and no significant difference in postoperative complications. There was a trend over the study period toward faster operative times and more robotic repair. Robotic repair is the most expensive repair, followed by laparoscopic and open repairs.

CONCLUSION

All 3 repair techniques can be performed without significant differences in outcomes. The technique utilized should be based on surgeon preference and patient characteristics.

Comparison of Early Outcomes in Patients Undergoing Suture Fixation Versus Tack Fixation of Mesh in Laparoscopic Transabdominal Preperitoneal (TAPP) Repair of Inguinal Hernia

Introduction: The advent of laparoscopic techniques in repairing inguinal hernia has significantly improved outcomes of inguinal hernia surgery. However, acute and chronic postoperative pain after fixation of mesh with tacks and the cost of tacking devices are major hindrances to the widespread use of laparoscopic transabdominal preperitoneal (TAPP) repair in resource-poor settings. This study sought to introduce a method of mesh fixation that will reduce the cost of laparoscopic TAPP repair and might help reduce postoperative pain.

Objective: To compare outcomes in the early postoperative period like pain, seroma, hematoma, urinary retention, and neuralgia after fixation with suture versus the tack fixation of mesh in laparoscopic TAPP repair of inguinal hernia. 

Subjects and methods: This study was conducted from 1^st June 2019 to 31^st May 2020. A total of 144 patients between ages 18 and 60 years with an inguinal hernia on any side and having an American Society of Anaesthesiologists (ASA) score of I/II were included in this study. Patients with a recurrent hernia, large scrotal hernia, strangulated and obstructed hernias, ASA III and ASA IV, prostatism, and chronic cough were excluded. Seventy-two patients were in Group A (tack fixation group) while 72 were in Group B (suture fixation group). Separate investigators were assigned to collect pre-operative and post-operative data from both groups, recorded on specially designed proforma.

Results: The age range was 18 to 60 years with a mean age of 46.53 years ±10.01 S.D in Group A and 46.19 ±9.58 S.D in Group B. In Group A 98.6% of patients were male, and 1.4% were females while in Group B 100% of patients were male. It was found that mean pain in Group A was 4.88 ±0.887 and 5.29± 0.777 at 6 hours and 24 hours respectively. Mean pain in group B was 3.43 ±0.962 and 4.11±0.703 at 6 hours and 24 hours respectively. Moreover, mean pain in Group B was significantly less than mean pain in Group A both at 6 hours and 24 hours intervals with a p-value < 0.001. The early postoperative complications were not significantly different in both groups. 

Conclusion: In TAPP repair, suture fixation of mesh is less painful than tack fixation. However, there is no significant difference in the rate of other early postoperative outcomes like seroma, hematoma, urinary retention, and neuralgia. Further multicentric studies with a longer duration of follow-up are needed to validate our results.

[Pain and quality of life after laparoscopic transabdominal preperitoneal hernioplasty with different ways of fixing the peritoneum. Results of early completion randomized clinical trial]

OBJECTIVE

To compare and statistically evaluate the severity of pain syndrome and quality of life depending on the method of fixation of the parietal peritoneum during laparoscopic hernia repair (suture fixation or the use of tack fixation).

METHODS

A randomized clinical trial was conducted from May to June 2021 at the Lomonosov Moscow State University Medical Center. It was planned to observe patients for a year. In the first group, the fixation of the parietal peritoneum was performed using suture fixation, in the second group, the peritoneal flap was fixed using a fixation device. In the course of statistical data processing, it was planned to study the dependence of the duration of the operation, the severity of the pain syndrome in the early postoperative period, the frequency of complications, the quality of life of patients in the postoperative period on the chosen method of the fixation of the parietal peritoneum.

RESULTS

At the initial stage of the study, 8 patients with inguinal hernias were selected in the first group during randomization, and 6 patients were selected in the second group. Each patient of the second group in the early postoperative period had a more pronounced local pain, protective muscle tension in the projection of fixation of the parietal peritoneum with tacks, which was accompanied by negative psychoemotional reactions, an increase in the dose of analgesic drugs. Due to the revealed features of the early postoperative period in patients of second group, it was considered unethical and inappropriate to continue the study within the protocol.

CONCLUSION

The results obtained do not allow us to draw statistically supported conclusions. The solution of the problem of the peritoneal flap fixation method is possible in two ways: abandoning stapler fixation in favor of suture or conducting additional clinical studies with an analysis of the impact of the choice of peritoneal fixation technique not only on acute and chronic postoperative pain, but on quality of life in the early and delayed postoperative periods.

Mind the gap - Small bowel obstruction due to preperitoneal herniation following laparoscopic inguinal hernia repair - A case report

INTRODUCTION AND IMPORTANCE

Inguinal hernia repair is a very frequent operation in general and visceral surgery worldwide. The laparo-endoscopic approaches such as TAPP have gained increasing acceptance among specialists and many consider them as standard of care due to perioperative safety and excellent postoperative results. Knowledge of specific complications after minimally invasive inguinal hernia surgery, however, is important for the successful management of these patients.

CASE PRESENTATION

We herein present the case of a 75-year-old female patient who electively underwent laparoscopic repair of combined inguinal and femoral hernia. During the postoperative course a small bowel obstruction occurred requiring emergency re-laparoscopy revealing a preperitoneal herniation of small bowel through a peritoneal defect.

CLINICAL DISCUSSION

Small bowel obstruction due to preperitoneal herniation of small bowel through a peritoneal defect after laparoscopic hernia repair is extremely rare. In such cases, emergency laparoscopic revision is necessary to avoid bowel ischaemia. Adequate closure of the peritoneum during the primary procedure along with the necessary attention to detail seems mandatory to avoid preperitoneal herniation after TAPP.

CONCLUSION

Inadequate peritoneal closure after TAPP may lead to preperitoneal herniation of the small bowel leading to postoperative intestinal obstruction. All hernia surgeons should be aware of this rare, but potentially life-threatening complication and should close all peritoneal defects with greatest care and accuracy.

Comparison of Common Postoperative Complications Between Lichtenstein Open Repair and Laparoscopic Transabdominal Pre-peritoneal (TAPP) Repair for Unilateral Inguinal Hernia

Introduction

Laparoscopic transabdominal pre-peritoneal (TAPP) repair is a minimally invasive technique that is becoming the procedure of choice among surgeons for inguinal hernia repair and research work is still going on comparing TAPP repair with Lichtenstein open mesh repair. The objective of our study is to compare common postoperative complications in Lichtenstein mesh repair and laparoscopic TAPP repair for unilateral inguinal hernia in our unit.

Methods

Between August 2016 and August 2018, patients with unilateral inguinal hernia and ASA grade I/II were selected in the surgical outpatient department (OPD) and prospectively randomized into two equal groups. Lichtenstein open mesh repair was done in Group-I and laparoscopic TAPP repair in Group-II. The visual analog scale (VAS) was used for the assessment of the intensity of pain.

Results

A total of 100 patients with a diagnosis of unilateral inguinal hernia were included in the study. Overall, our study showed that there was less postoperative pain in those patients who underwent TAPP repair as compared to patients with Lichtenstein mesh repair (p= <0.05). There were more postoperative complications in Group-I as compared to Group-II.

Conclusion

Laparoscopic TAPP repair for inguinal hernia is associated with less postoperative pain and other postoperative complications in addition to a shorter hospital stay as compared to Lichtenstein mesh repair. Thus, this is helping in the early return of patients to daily life activities.

Laparoscopic Transabdominal Preperitoneal (TAPP) Inguinal Hernia Repair Using Fibrin Glue for Fixation of the Mesh and Peritoneum Closure

PURPOSE

The aim of this case series is to describe our ongoing experience of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair using Tisseel fibrin glue for the fixation of the mesh and peritoneum closure.

MATERIALS AND METHODS

From October 2018, patients who underwent laparoscopic TAPP for unilateral inguinal hernia repair using Tisseel fibrin glue to secure the mesh and the peritoneum, with a minimum of 1 year of follow-up, have been included. Patient demographics, main operative findings, and main postoperative outcomes were analyzed prospectively using a visual analgesic scale (VAS) and a modified short-form 36 (SF-36) questionnaire.

RESULTS

A total of 26 patients have been included and none have been lost during the follow-up. The mean operative time was 92.1 minutes and there was no conversion. The median hospital stay was 1.03 day (range, 1 to 2). The mean follow-up duration was 19.3 months (range, 12 to 26 mo) and none had a recurrence. The postoperative VAS score at 1, 7, 30 days, and 6 months from surgery was 3.18, 1.52, 0, and 0, respectively. The mean SF-36 score at 1, 6, and 12 months from surgery was 90.09, 94.8, and 05.1, respectively.

CONCLUSIONS

The use of fibrin glue for TAPP inguinal hernia repair is a safe and feasible technique with favorable results. Larger comparative randomized studies are needed to confirm these early results.

Recurrent abdominal pain due to small bowel volvulus after transabdominal preperitoneal hernioplasty: A case report and review of literature

BACKGROUND

Compared with open mesh repair, transabdominal preperitoneal (TAPP) hernioplasty results in less chronic postoperative inguinal pain and faster postoperative recovery. However, it may still lead to rare but serious complications. Here we report a case of intestinal volvulus with recurrent abdominal pain as the only clinical symptom, which occurred 3 mo after TAPP repair for bilateral inguinal hernia.

CASE SUMMARY

A 50-year-old male patient underwent laparoscopic TAPP for bilateral inguinal hernias. After the operation, he experienced recurring pain in his lower right abdomen around the surgical area, which was relieved after symptomatic treatment. Three months after the surgery, the abdominal pain became severe and was aggravated over time. The whirlpool sign of the mesentery was seen on contrast-enhanced computed tomography (CT). Laparoscopic exploration confirmed that a barb of the V-Loc™ suture penetrated the peritoneum, which caused the adhesion of the small intestinal wall to the site of peritoneal injury, forming intestinal volvulus. Since there was no closed-loop obstruction or intestinal ischemia, recurrent abdominal pain became the only clinical manifestation in this case. After laparoscopic lysis of adhesions and reduction of intestinal volvulus, the patient recovered and was discharged.

CONCLUSION

The possibility of intestinal volvulus should be considered in patients who experience recurrent abdominal pain following TAPP surgery during which barbed V-Loc sutures are used for closing the peritoneum. Contrast-enhanced CT and active laparoscopic exploration can confirm the diagnosis and prevent serious complications.

Laparoscopic inguinal hernia repair: cost-effectiveness analysis of trend modifications of the technique

The aim of this study is to evaluate the cost-effectiveness of different modifications of the trans-abdominal pre-peritoneal (TAPP) repair of groin hernia. Data were collected prospectively for all consecutive patients who underwent TAPP unilateral inguinal hernia repair between November 2017 and March 2019, and who completed a minimum of 1 year of follow-up. Costs and quality adjusted life year (QALY) gained were collected. Three TAPP variations were assessed: mesh fixation and peritoneal closure with staples (group 1); mesh fixation with fibrin glue and peritoneal closure with sutures (group 2); and mesh fixation and peritoneal closure with fibrin glue (group 3). A matched group of open repairs was established. The incremental cost-effectiveness ratio (ICER) and main intra-operative and post-operative outcomes were assessed. Overall 120 patients were included (group 1 n = 31; group 2 n = 27; group 3 n = 33; open group: 29). Operative time was shorter for groups 2 and 3, and the main post-operative outcomes were similar. The overall mean total cost of the open group (1185.95€) was lower compared with the laparoscopic group (group 1: 1682.39; group 2: 1538.54€; group 3: 1510.1€) (p = 0.026). However, the mean ICERs of groups 2 and 3 were significantly higher compared with group 1 (p = 0.021) and the open group (p = 0.032). At simulations analysis, the probability of cost-effectiveness was 33.32%, 36.26%, and 36.7% in TAPP groups 1, 2, and 3. In the long term, laparoscopic repair of groin hernia is cost-effective compared with open surgery. The use of fibrin glue for mesh fixation and/or for closing the peritoneum is the most cost-effective option and shortens operative times.

Propensity score analysis of outcomes between the transabdominal preperitoneal and open Lichtenstein repair techniques for inguinal hernia repair: a single-center experience

BACKGROUND

The mechanism of persistent chronic pain after TAPP and OLR remains controversial. Therefore, more prospective and well-designed studies are needed to determine the predictive risk factors that will lead to better pain prevention and possibly elimination. The aim of the present study was to investigate the risk factors of chronic pain after TAPP repair and OLR in a single institution.

METHODS

A single-center, retrospective study of propensity score-matched patients who underwent TAPP or OLR surgery between 2008 and 2018 was conducted. To overcome selection bias, we performed 1:1 matching using 6 covariates to generate the propensity score.

RESULTS

A total of 400 patients treated with TAPP and 424 patients treated with OLR were balanced to 400 pairs of matched patients. The patients' age (P < 0.001), BMI (P < 0.001), foreign body sensation within 3 months after surgery (P < 0.001), and persistent sensation loss (P = 0.002) were different between the two groups. The OLR group had a shorter operative time than did the TAPP group (P < 0.001). The univariate analysis of factors predicting a difference in VAS between the preoperative assessment and the assessment 3 months after surgery showed that the type of surgery (P = 0.004), hernia grade (P = 0.001), type of mesh (P < 0.001), presence of scrotal invasion (P = 0.024), and foreign body sensation within 3 months (P = 0.047) were risk factors. The multivariate analysis revealed that only hernia grade III (CI - 8.524, - 2.783; P < 0.001), OLR operation type (CI 1.069, 4.987; P = 0.002), and the use of polypropylene mesh (CI - 5.400, - 1.489; P = 0.001) were independently associated with chronic pain.

CONCLUSION

These results suggest that compared to OLR, TAPP leads to less postoperative pain and a better long-term quality of life.

Comparison of peritoneal closure versus non-closure in laparoscopic trans-abdominal preperitoneal inguinal hernia repair with coated mesh

BACKGROUND

Peritoneal closure during laparoscopic trans-abdominal preperitoneal (TAPP) inguinal hernia repair has been the standard of care to prevent bowel obstruction due to adhesions generated by contact with mesh. However, with newer coated meshes, leaving the peritoneal layer open may be safe. While many studies compare methods of peritoneal flap closure, there is a deficit of literature reporting the outcomes of non-closure.

METHODS

A retrospective comparison of peritoneal flap closure versus non-closure during primary laparoscopic TAPP inguinal hernia repair with coated mesh was performed for all patients at Baystate Medical Center meeting inclusion criteria between January 2005 and August 2016. Primary outcome was any procedure-related adverse outcome following repair. Secondary outcomes included operative time, resolution of pre-operative pain and/or gastrointestinal symptoms, and hernia recurrence.

RESULTS

Of 231 patients, 55 (24%) underwent peritoneal flap closure and 176 (76%) underwent non-closure. Demographic, comorbidity, and hernia characteristics were comparable between groups with the exception of obesity (p = 0.01), current smoking status (p = 0.05) and hernia side [p = 0.04 (left), 0.0003 (right)]. Mean operative time was higher in the closure group than non-closure (98.1 ± 37.1 min vs. 76.8 ± 32.9, p < 0.0001). No cases were converted to open. Average follow-up was 21.6 ± 23.8 months. Ninety-three percent of closure patients had documented resolution of pre-operative pain versus 94.0% of non-closure (p = 0.81). The closure group experienced a higher percentage of post-operative complications, though this did not reach significance (5.5 vs. 2.3%; p = 0.36). Compared to the closure group, the non-closure groups experienced similar post-operative pain (3.6 vs. 1.2%; p = 0.24) and recurrence rate (1.8 vs. 4.0%; p = 0.68). There were no bowel obstructions, surgical site infections, unplanned readmissions, or unplanned re-operations.

CONCLUSIONS

Equivalent patient outcomes were seen for both procedure types post-operatively and during follow-up. Operative times were significantly shorter for non-closure patients. Larger study population and longer follow-up is necessary to evaluate true long-term complication rates in flap non-closure.

A prospective randomized study comparing laparoscopic transabdominal preperitoneal (TAPP) versus Lichtenstein repair for bilateral inguinal hernias

BACKGROUND

In literature, only a few studies have prospectively compared the results of laparoscopic with open inguinal hernia repair yet none have compared bilateral inguinal hernia repair. The aim of this study is to compare the open Lichtenstein repair (OLR) with laparoscopic trans-abdominal preperitoneal (TAPP) repair in patients undergoing surgery for bilateral inguinal hernia.

METHODS

Patients were prospectively randomized between March 2013 and March 2015. Outcome parameters included hospital stay, operation time, postoperative complications, immediate postoperative pain and chronic pain, recurrence and quality of life.

RESULTS

Sixty-one patients underwent TAPP repair and 73 underwent OLR. TAPP procedure had less early post-operative pain up to 7 days from surgery (p = 0.003), a shorter length of hospital stay (p = 0.001), less postoperative complications (p = 0.012) and less chronic pain (0.04) when compared with the OLR approach.

CONCLUSIONS

TAPP procedure for bilateral inguinal hernia effectively reduces early postoperative pain, hospital stay and postoperative complications.

Single-Incision Laparoscopic Inguinal Hernioplasty Versus Conventional Laparoscopic Inguinal Hernioplasty

PURPOSE

Additional studies comparing single-incision laparoscopic inguinal hernioplasty (SILH) and conventional laparoscopic inguinal hernioplasty (CLH) have been published, and this study updates the meta-analysis of this subject.

METHODS

Two reviewers independently searched the PubMed, Embase, Google Scholar, and Cochrane Library electronic databases to locate original articles that compared SILH and CLH for inguinal hernia that were published until October 2015. Operative time, conversions, complications, length of hospital stay, recurrence, postoperative pain at 24 hours, and postoperative pain at 7 days were compared using Stata software, version 12.0.

RESULTS

Sixteen studies were selected for this analysis, which included a total of 1672 patients (907 in SILH and 765 in CLH). SILH showed a longer operative time; however, conversions, complications, length of hospital stay, recurrence, postoperative pain at 24 hours, and postoperative pain at 7 days were similar between the 2 groups.

CONCLUSIONS

Our meta-analysis has shown that inguinal hernia repair using SILH is as safe as CLH. However, based on our evidence, we currently believe that SILH is not an efficacious surgical alternative to CLH for inguinal hernias due to the fact that it does not provide significant benefit in postoperative pain and cosmetic outcomes. However, large-scale, well-designed, and multicenter studies will be needed to further confirm the results of this study.

Does peritoneal flap closure technique following transabdominal preperitoneal (TAPP) inguinal hernia repair make a difference in postoperative pain? A long-term quality of life comparison

BACKGROUND

Transabdominal, preperitoneal (TAPP), laparoscopic inguinal hernia repair (IHR) requires the creation of a peritoneal flap (PF) that must be closed after mesh placement. Our previous study indicated that sutured PF closure resulted in less short-term postoperative pain at 2 and 4 weeks compared to tacks and staples. Therefore, the aim of this follow-up study was to compare short-term QOL with a greater sample size and long-term QOL at 2 years by method of PF closure.

MATERIALS AND METHODS

A prospective institutional hernia-specific database was assessed for all adult TAPP IHRs from July 2012 to May 2015. QOL outcomes were compared by PF closure method at 2 and 4 weeks and 6, 12, and 24 months as measured by the Carolinas Comfort Scale. Standard statistical tests were used for the whole population and then the Bonferroni Correction was used to compare groups (p < 0.0167). Multivariate analysis controlling for age, gender, recurrent hernias, and preoperative symptomatic pain was used to compare QOL by PF closure method.

RESULTS

A total of 679 TAPP IHRs in 466 patients were analyzed; 253 were unilateral, and 213 were bilateral. PF closure was performed using tacks in 36.7 %, suture in 24.3 %, and staples in 39.0 %. There was no difference in hernia recurrence (only 1 patient at 36 months). There were no statistical differences in QOL between 2 and 4 weeks and 6- to 24-month follow-up. When resolution of symptoms from preoperative levels was examined, there was no difference in the three groups at any time point (p > 0.05). After controlling for confounding variables on multivariate analysis, there was no difference in QOL by PF closure method at any time point (p > 0.05).

CONCLUSION

Tacked, sutured, and stapled techniques for peritoneal flap closure following TAPP have no significant differences in operative outcomes, postoperative quality of life, or resolution of symptoms.
