Laparoscopic Inguinal Herniorrhaphy Research Articles

Safety and efficacy revisited: a systematic review and meta-analysis of glue versus tack mesh fixation in laparoscopic inguinal herniorrhaphy.

This analysis addresses the uncertainty surrounding the efficacy of glue mesh fixation (GMF) compared with tack mesh fixation (TMF) in laparoscopic herniorrhaphy. Our meta-analysis incorporates recently conducted randomized controlled trials (RCTs) to enhance the reference for assessing the efficacy and safety of GMF. PubMed Central, Google Scholar, Science Direct, and Cochrane Library were extensively reviewed for articles in the English language performed from inception to May 2023 using the keywords "Glue mesh repair," "Tack mesh repair," "Inguinal Hernia," "Herniorrhaphy," "Laparoscopic," "Mesh Fixation," and "Randomized controlled trials." In this meta-analysis, we incorporated a total of 20 randomized controlled trials, evaluating each article individually using quality ratings. Compared with TMF, GMF demonstrated a significant reduction in the incidence of chronic pain [RR: 0.40, (0.23, 0.68)] and pain scores on postoperative day 1 [MD: -1.07, (-1.90, -0.25)]. We also used funnel plots and Egger's regression to test for publication bias. In summary, this meta-analysis establishes the significance of GMF in reducing chronic pain and postoperative day 1 pain compared with TMF. However, no statistically significant difference was noted between the GMF and TMF groups concerning hematoma, seroma, operation time, recurrence rate, and total complications. Nonetheless, given the small number of cases in this study, the findings must be validated in the future by multicenter, large-sample, high-quality RCTs.

Immediate Dialysis After Simultaneous Laparoscopic Peritoneal Dialysis Catheter Placement and Laparoscopic Inguinal Hernia Repair.

Peritoneal dialysis (PD) is an accepted renal replacement therapy for end-stage renal disease (ESRD). Managing inguinal hernia in patients with PD is not standardized. Thus, this study reported the outcomes of simultaneous laparoscopic peritoneal dialysis catheter (PDC) placement and transabdominal preperitoneal (TAPP) repair of inguinal hernia. Thirteen patients with chronic renal disease and inguinal hernia attending a tertiary hospital between May 1, 2016 and June 30, 2021 were evaluated for laparoscopic PDC placement. Concurrent laparoscopic inguinal herniorrhaphy and laparoscopic PDC placement were performed. Dialysate fluid was measured intraoperatively to the level below the incised peritoneum by 1 inch. The inflow and outflow was smooth without leakage. The amount was increased gradually in the two weeks after regular PD was obtained. Laparoscopic PDC was inserted for 13 patients. Ten patients had unilateral hernia and two had bilateral inguinal hernia. Associated paraumbilical hernia was discovered in two patients. The median follow-up was 30 months. The measured safe amount of dialysate fluid intraoperatively was 400 - 600 mL. There was no death, intraoperative complication, or dialysate leakage. Three PDCs were removed owing to noncompliance. No hernia recurrence was observed. Simultaneous laparoscopic PDC placement and laparoscopic repair of inguinal hernia with immediate dialysis is a safe and feasible surgical technique. Utilizing minimally invasive surgery affords PDC placement and inguinal hernia repair simultaneously.

Effects of deep neuromuscular block on surgical pleth index-guided remifentanil administration in laparoscopic herniorrhaphy: a prospective randomized trial

Deep neuromuscular block (NMB) has been increasingly utilized, but its role in reducing intraoperative opioid requirement has yet to be investigated. Surgical pleth index (SPI) quantifies nociception. We investigated the effects of deep NMB on SPI-guided remifentanil administration in laparoscopic herniorrhaphy. Total 128 patients undergoing laparoscopic inguinal herniorrhaphy were randomly allocated to two groups of NMB: deep (n = 64) and moderate (n = 64). The remifentanil dose was assessed during intubation, from skin incision until CO2 insertion, and pneumoperitoneum. Mean infusion rate of remifentanil during pneumoperitoneum was higher in moderate NMB group than in deep NMB group (0.103 [0.075–0.143] µg/kg/min vs. 0.073 [0.056–0.097] µg/kg/min, p < 0.001). Consequently, median infusion rate of remifentanil during anesthesia was higher in moderate NMB group (0.076 [0.096–0.067] µg/kg/min vs. 0.067 [0.084–0.058] µg/kg/min, p = 0.016). The duration of post-anesthesia care unit stay was longer in the moderate NMB group (40 [30–40] min vs. 30 [30–40] min, p = 0.045). In conclusion, deep NMB reduced the remifentanil requirement compared with moderate NMB in SPI-guided anesthesia for laparoscopic herniorrhaphy.

Efficacy of dexmedetomidine versus magnesium sulfate as an adjuvant to intraperitoneal bupivacaine in pediatric laparoscopic surgery: a randomized clinical trial

BackgroundWe evaluated the efficacy of dexmedetomidine versus magnesium sulfate as an adjuvant to intraperitoneal (IP) bupivacaine in pediatric laparoscopic inguinal herniorrhaphy. MethodsNinety-seven male children, ASA I–II, 1–6 years old, undergoing laparoscopic inguinal herniorrhaphy, were randomized to receive before peritoneal insufflation, IP 2 mg.kg−1 bupivacaine 0.5% combined with either 1 μg.kg−1 of dexmedetomidine (Group D), 30 mg.kg−1 of magnesium sulfate (Group M), or normal saline (Group C). All tested drugs were diluted to the volume of 10 mL with normal saline. FLACC pain scores, need for rescue analgesics, time to flatus and first stool, emetic events, adverse effects, functional recovery, and parents’ satisfaction were recorded for the first 48 h postoperatively. ResultsFLACC scores were significantly higher in Group C than in the other two groups at 6, 8, 12, 18, 24, and 48 hours after surgery with no differences between Groups D and M. Rescue analgesia was significantly higher in Group C with none of the children in Groups D and M requiring rescue analgesia (p = 0.001). Times to first flatus and stool, emetic events, and adverse effects did not differ among groups. Times to return to normal functional activity were comparable in all groups. Parents’ satisfaction was greater in Groups D and M than in Group C (p = 0.026). ConclusionDexmedetomidine and magnesium sulfate added to IP bupivacaine improved the analgesia afforded by bupivacaine in the first two postoperative days in children scheduled for laparoscopic herniorrhaphy.

Tele-consent using mixed reality glasses (NREAL) in pediatric inguinal herniorrhaphy: a preliminary study

There is an increasing demand and need for patients and caregivers to actively participate in the treatment process. However, when there are unexpected findings during pediatrics surgery, access restrictions in the operating room may lead to a lack of understanding of the medical condition, as the caregivers are forced to indirectly hear about it. To overcome this, we designed a tele-consent system that operates through a specially constructed mixed reality (MR) environment during surgery. We enrolled 11 patients with unilateral inguinal hernia and their caregivers among the patients undergoing laparoscopic inguinal herniorrhaphy between January through February 2021. The caregivers were informed of the intraoperative findings in real-time through MR glasses outside the operating room. After surgery, we conducted questionnaire surveys to evaluate the satisfaction and usefulness of tele-consent. We identified contralateral patent processus vaginalis in seven out of 11 patients, and then additionally performed surgery on the contralateral side with tele-consent from their caregivers. Most caregivers and surgeons answered positively about the satisfaction and usefulness of tele-consent. This study found that tele-consent with caregivers using MR glasses not only increased the satisfaction of caregivers and surgeons, but also helped to accommodate real-time findings by adapting surgical plan through the tele-consent.

Laparoscopic inguinal herniotomy: Recreating the open operation optimises outcomes

BackgroundRecent evidence suggests simple laparoscopic inguinal herniorrhaphy is associated with higher rates of recurrence and testicular ascent. We instigated a standardised approach to laparoscopic inguinal herniotomy (LIH), with circumferential sac division and ‘purse-string’ closure (4/0 monofilament polypropylene). An active follow-up programme was pursued. We reviewed our outcomes of this technique and compared them to an open herniotomy (OIH) cohort. MethodsLIH patients were identified prospectively (2017–2021): OIH retrospectively from 2016. Risk factors for complications were defined: extremely to very preterm (< 32 weeks), emergency presentation with incarceration, and redo surgery for recurrence. Data are presented as median [IQR]. Comparisons used Fisher's exact and Mann-Whitney U tests: significance defined as p < 0.05. Results192 inguinal herniae in 140 patients were included in the LIH group and 214 herniae in 179 patients in the OIH group. Groups were similar in age and gender. The LIH group had a significantly larger proportion of cases that were premature, had emergency surgery, or had redo surgery after previous OIH. Follow-up was 24.4 months [10.8–33.6] vs. 66.4 [64.5–68.5] (LIH vs. OIH). Hernia recurrence occurred in 2/192 (1.0%) vs. 4/214 (1.9%) (LIH vs. OIH), p = 0.69. There was one known case of testicular ascent after OIH but none in the LIH group. ConclusionsRecreation of the open herniotomy laparoscopically appears to confer excellent outcomes, with low rates of recurrence despite a high proportion of patients having known risk factors. Further long-term data on rates of testicular ascent after active follow-up are required.

Safety of two common laparoscopic inguinal herniorrhaphy approaches: an updated systematic review with meta-analysis of randomized clinical trials.

BackgroundPrevious evidence indicated that total extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) are advantageous in efficacy of inguinal herniorrhaphy. Therefore, our aim in this study was to evaluate the association of the two laparoscopic approaches on safety of inguinal herniorrhaphy.MethodsIn this update study, we searched the Cochrane Library, EMBASE, PubMed, Scopus, and Web of Science and identified randomized clinical trials comparing complications in TEP and TAPP herniorrhaphy. We mainly used Peto odds ratio with 95% confidence interval (CI) for meta-analysis because of zero-cell.ResultsFourteen eligible trials recruited 659 and 682 patients in TEP and TAPP respectively. In overall pooling, although TEP had a higher seroma rate than TAPP (Peto odds ratio =2.01; 95% CI, 1.39 to 2.91), it had a lower scrotal/cord edema rates at immediate postoperative (Peto odds ratio =0.22; 95% CI, 0.09 to 0.57) and 1 week after inguinal hernia repair (Peto odds ratio =0.58; 95% CI, 0.37 to 0.91) than TAPP.ConclusionsTEP and TAPP have their own advantages in inguinal herniorrhaphy. TAPP was associated with a lower seroma rate, and TEP was associated with a lower edema rate. Therefore, shared decision-making on laparoscopic inguinal herniorrhaphy with TEP and TAPP is still needed.

Trans-umbilical single-incision laparoscopic trans-abdominal pre-peritoneal hernioplasty of inguinal hernia by self-made glove port

Laparoscopic inguinal herniorrhaphy has been well established for the management of primary and recurrent inguinal hernias. Single-incision laparoscopic surgery (SILS) has now been accepted as a less invasive alternative to conventional laparoscopic surgery. However, commercially available access devices for SILS had disadvantages such as rigidness and crowding. This series aimed to analyze the feasibility and safety of single-incision laparoscopic trans-abdominal pre-peritoneal hernioplasty (SILS-TAPP) by applying our self-made device for managing inguinal hernia.We collected and reviewed the medical records of patients who received SILS-TAPP using a self-made glove-port device between January 2014 and January 2016. All operations were performed by the same surgical team. The demographics and intra- and perioperative outcomes were evaluated.SILS-TAPP was successfully performed in 105 patients (131 inguinal hernia repairs). No major intra- and postoperative morbidities were encountered, and no conversion to a conventional 3-port approach or open surgery was required. The mean operative time was 73.5 min and the mean postoperative hospital stay was 2.1 days. Three minor short-term complications were noted, which were resolved without surgical intervention. One recurrence was diagnosed during follow-up and treated using a second TAPP procedure.SILS-TAPP was shown to be a feasible, safe procedure in patients with an inguinal hernia. A simple self-made glove-port device was proven as a practical method of SILS-TAPP.

Single-incision approach for bilateral inguinal hernia repair in children: A retrospective study.

To introduce the use of a new surgical approach named single-incision bilateral inguinal herniorrhaphy (SBIH) in pediatric surgical population.This was a STROBE-compliant retrospective cohort study using data from 101 patients who had undergone bilateral inguinal herniorrhaphy in our institution. Children with bilateral inguinal hernias without contraindications for surgery, ranging in age from 6 months to 12 years, were included. Fifty-six children with bilateral inguinal hernias underwent SBIH (SBIH group) and 45 patients underwent laparoscopic bilateral inguinal herniorrhaphy (LBIH) (LBIH group). Differences in operative time, postoperative pain, recurrence, and complications between the 2 groups were analyzed. Patient satisfaction with cosmetic result was also investigated using questionnaires.There were no statistically significant differences in operative time (P = .2257), postoperative pain (P = .0607), recurrence (P = .8756), and complications (P = .7467) between the 2 groups. Interestingly, the operation time of girls in SBIH group was significantly shorter than that of the boys in this group (P < .0001), but also shorter than that of girls in LBIH group (P = .0038). Postoperative pain for boys was lower in SBIH group than in the LBIH group (P = .0340). No ascending testis, testicular atrophy, and hydrocele occurred in either group. According to the questionnaire, both procedures had equally high levels of satisfaction for cosmetic results (P = .7531).Initial results show that SBIH for pediatric patients, regardless of gender, is a safe and feasible procedure compared with LBIH with an equally low recurrence rate, few complication, and satisfactory cosmetic outcomes.

A randomized study on laparoscopic total extraperitoneal inguinal hernia repair with hernia sac transection vs complete sac reduction.

The management of the hernia sac is the core step of laparoscopic indirect inguinal hernioplasty. In this study, a randomized controlled trial was conducted to evaluate the clinical effect of laparoscopic total extraperitoneal inguinal herniorrhaphy (TEP) with hernia sac transection and complete sac reduction. From May 2017 to May 2018, 70 patients aged 18-75 with primary indirect inguinal hernia in our hospital were randomly divided into a transected sac group (TS) and a completely reduced sac group (RS). The primary outcomes compared between the two groups were the hernia sac treatment time, operation time, and the incidence of seroma formation after operation. Secondary outcomes included acute pain, chronic pain (pain which lasted for at least 3months), hospital stay, recurrence rate, and other complications. There were no significant differences in baseline demographic characteristics including age, sex, hernia type, size of hernia defect, and follow-up time between the two groups. The times required for hernia sac separation and operation in the TS group were significantly shorter than in the control group (6.1 ± 2.3 vs. 25 ± 5.8min for hernia sac separation, p < 0.01; and 35.10 ± 3.50 vs. 54.40 ± 4.20min for operation, p < 0.01). There was no significant difference in hospitalization time, incidence of acute pain, seroma formation, or urinary retention between the two groups. During the 12-month follow-up period, chronic pain, early recurrence, and other complications were not found in either group. Both the hernia sac transection technique and the complete sac reduction technique are safe and reliable. The hernia sac transection technique is a simple and effective hernia sac treatment method. It reduces the operation time and does not increase seroma or acute or chronic pain. It is valuable and likely to be popularly applied.

Pediatric inguinal hernia treated by single-port laparoscopic water injection hernia crochet needle.

IntroductionInguinal hernia is the most common disease in pediatric surgery and is induced by congenital processus vaginalis patency. Almost all inguinal hernias are inguinal indirect hernias, and herniorrhaphy has accounted for about 15% of all pediatric operations. In the past 20 years, with the development of minimally invasive technology, laparoscopic inguinal herniorrhaphy has been emerging in China and in other countries.AimTo introduce a new technique for treating inguinal hernia in children, and evaluate the feasibility and surgical efficacy of a transumbilical single-port laparoscopic water-injection hernia crochet needle in treating pediatric inguinal hernia.Material and methodsClinical data of 136 inguinal hernial children treated using a transumbilical single-port laparoscopic water-injection hernia crochet needle in our hospital from June 2017 to December 2018 were retrospectively analyzed.ResultsAll procedures were successfully accomplished, and no case was converted to a different procedure; the average operation time was 16 min for one side and 35 min for both sides. Patients were followed for an average of 10 months after surgery. One patient had a line-knot reaction at the inguinal puncture point 3 months after surgery and recovered after conservative treatment, and no recurrent case was observed after surgery.ConclusionsIt is feasible to treat pediatric inguinal hernia through a transumbilical single-port laparoscopic water-injection hernia crochet needle, which is associated with safety, less trauma, rapid recovery, no obvious scar, and satisfactory efficacy. Therefore, it is worthy of being promoted and applied in clinical practice.

Simultaneous robotic assisted laparoscopic prostatectomy (RALP) and inguinal herniorrhaphy (IHR): proof-of-concept analysis from a high-volume center.

Inguinal hernia (IH) is detected in approximately 33% of RALP's either pre or intraoperatively wherein all are repaired during RALP to circumvent future herniorrhaphy (Fukuta et al., Urology 68(2):267-271, 2006; Nielsen, Urology 66(5):1034-1037, 2005). Some debate this policy by quoting the potential risk of mesh lying close to the vesicourethral anastomosis leading to infections and adhesions. The current study was initiated to elucidate the feasibility and outcomes of simultaneous inguinal herniorrhaphy (IHR) during RALP. Historic analysis of prospectively maintained data of 1224 RALP patients, as per inclusion criteria, between 2012 and 2017 was done, among whom 143 patients had a concurrent IHR using 3DmaxTM polypropylene monofilament mesh. Patients were then compared for demographics, peri-operative features, and outcomes. The mean age and AUA score were significantly different (p < 0.002, p < 0.01 respectively) between patients undergoing only RALP and RALP with IHR. BMI was not significantly different. One hundred forty-three patients (11.6%) underwent IHR at 155 hernial sites, 12 sites being bilateral. One hundred and one sites (65.2%) were diagnosed intraoperatively. The mean console time was 67.4 ± 11.5min for RALP which increased by 6.9 ± 10.7min in unilateral and by 10.7 ± 8.6min in bilateral IHR. There were no mesh-associated or Clavien Dindo class II-V complications. Mean follow-up was 36 ± 1.4months with no recurrences. This study reiterates the feasibility and advisability of repairing most inguinal hernias encountered during RALP as it is without any significant alteration of peri-operative morbidity, is associated with excellent post-operative outcomes, and obviates the need for a future surgical procedure.

Left Side Approach in Laparoscopic Transabdominal Preperitoneal Inguinal Herniorrhaphy is Feasible for Any Type of Inguinal Hernia

Left Side Approach in Laparoscopic Transabdominal Preperitoneal Inguinal Herniorrhaphy is Feasible for Any Type of Inguinal Hernia

Causes of recurrence in laparoscopic inguinal hernia repair.

Recurrence after laparoscopic inguinal herniorrhaphy is poorly understood. Reports suggest that up to 13% of all inguinal herniorrhaphies worldwide, irrespective of the approach, are repaired for recurrence. We aim to review the risk factors responsible for these recurrences in laparoscopic mesh techniques. A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified English language, peer reviewed articles on the causes of recurrence following laparoscopic mesh inguinal herniorrhaphy published between 1990 and 2018. The search terms included 'Laparoscopic methods', 'Inguinal hernia; Mesh repair', 'Recurrence', 'Causes', 'Humans'. The literature revealed several contributing risk factors that were responsible for recurrence following laparoscopic mesh inguinal herniorrhaphy. These included modifiable and non-modifiable risk factors related to patient and surgical techniques. Recurrence can occur at any stage following inguinal hernia surgery. Patients' risk factors such as higher BMI, smoking, diabetes and postoperative surgical site infections increase the risk of recurrence and can be modified. Amongst the surgical factors, surgeon's experience, larger mesh with better tissue overlap and careful surgical techniques to reduce the incidence of seroma or hematoma help reduce the recurrence rate. Other factors including type of mesh and fixation of mesh have not shown any difference in the incidence of recurrence. It is hoped that future randomized controlled trials will address some of these issues and initiate preoperative management strategies to modify some of these risk factors to lower the risk of recurrence following laparoscopic inguinal herniorrhaphy.

Hemodynamic, Airway Pressure, and Capnometric Changes and Perioperative Outcome in Pediatric Laparoscopic Inguinal Herniorrhaphy: A Comparison with Open Inguinal Herniorrhaphy.

Background:Laparoscopic procedures which are now established in pediatric population as well exposes the child to supplemental cardiorespiratory changes due to increase in intraabdominal pressure (IAP) and hypercarbia.Aims:This study aims to analyze the effects of pneumoperitoneum and postural modifications on cardiorespiratory system (primary outcome) during pediatric laparoscopic herniorrhaphy (LH) and its comparison with open herniorrhaphy (OH) and assessment of overall perioperative outcome (secondary outcome).Settings and Design:A prospective, observational study conducted in a tertiary care hospital.Materials and Methods:Fifty children undergoing either LH (n = 25) or OH (n = 25) were included in the study. Anesthetic procedure was standardized. Parameters monitored were heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressures (MAP), electrocardiogram lead-II, end-tidal CO2 (ETCO2), airway pressures PPeak, PPlateau, PMean, pulse oximetry, IAP, minute ventilation/respiratory rate alterations.Statistical Analysis Used:Student's t-test and Chi-square test were applied to compare different variables between the two groups. Intragroup analysis was done using the analysis of variance test.Results:The HR was comparable in both groups. The rise in SBP, DBP, and MAP was 9% (102.88 ± 6.91–121.32 ± 6.63), 19% (60.88 ± 4.94–77.00 ± 9.75), and 14.8% (73.92 ± 4.65–90.40 ± 8.42), respectively, in group LH. The rise in peak, plateau, and mean airway pressures was 19.4% (14.20 ± 2.00–18.00 ± 2.54), 20.1% (13.32 ± 1.89–16.89 ± 2.60), and 16.1% (6.20 ± 1.00–7.47 ± 0.96), respectively, in group LH. ETCO2 showed a maximum rise of 19.4% (34.52 ± 3.61–41.21 ± 3.99) in group LH. In laparoscopic group, recurrence was seen in 3 patients.Conclusions:We found significant hemodynamic, airway pressure, and capnometric changes during pediatric LH with comparable perioperative outcome among the two groups.

Single-center, retrospective study of the outcome of laparoscopic inguinal herniorrhaphy in children.

Laparoscopic hernia repairs are used increasingly in children.The purpose of this single-center cohort observational research study was to analyze the outcome of children treated surgically for unilateral or bilateral inguinal hernia using laparoscopy.We did a STROBE-compliant retrospective outcome analysis of pediatric, laparoscopic hernia repair. Consecutive laparoscopic herniorrhaphies in 123 children done between March 2, 2010, and March 1, 2014, were included in this analysis. Data analysis was based on reviewing the hospital records and a prospective questionnaire. We evaluated postoperative hernia recurrence rate, occurrence of postoperative complications, duration of postoperative pain medication, and wound cosmesis.We first performed laparoscopic inguinal herniorrhaphy according to the techniques described by Schier et al and Becmeur et al in March 2010. We treated 46 girls and 77 boys with laparoscopically confirmed inguinal hernias, and their ages ranged from 0 to 16 years. Of these, 77 children suffered from unilateral hernias, 30 from unilateral hernias with contralateral patency of the vaginal process, and 16 from indirect bilateral hernias. The median follow-up interval was 38 months (range: 13–58 months). Overall, 8 (6.5%) of these 123 patients experienced a recurrence of the inguinal hernia. Two patients (1.6%) suffered a postoperative infection. Postoperative pain medication was administered by parents for 1 to 3 days in 67 (63.8%) of the 105 families who answered the question, and no pain medication was administered by 5 (4.0%) parents. Wound cosmesis was rated by the parents as invisible or barely visible in 106 (86.2%) of 123 patients and esthetically disturbing in 4 (3.2%) children.Laparoscopic inguinal hernia repair carries a learning curve and is safe and efficient in children thereafter. Further prospective studies are required to evaluate the long-term outcome of laparoscopic inguinal hernia repair in children.

Improved immediate postoperative pain following laparoscopic inguinal herniorrhaphy using self-adhering mesh.

Several synthetic meshes are available to reinforce the inguinal region following laparoscopic hernia reduction. We sought to compare postoperative pain of patients who underwent laparoscopic inguinal herniorrhaphy using self-adhering polyester mesh to those who had non-adhering, synthetic mesh implanted using absorbable tacks. This study is a retrospective review of patients who underwent primary laparoscopic inguinal herniorrhaphy at the Medical College of Wisconsin between October 2012 and July 2014. Clinical information and perioperative pain scores using the visual analog scale (VAS) were obtained to evaluate immediate pre and postoperative pain. A total of 98 patients (88 male) underwent laparoscopic inguinal herniorrhaphy during the study interval. Forty-two patients received self-adhering mesh and 56 patients received mesh secured with tacks. Patient demographics and comorbidities did not differ significantly between the two groups. There was no difference in preoperative VAS scores between groups. The self-adhering mesh patients had a lower mean VAS change score (less pain). Postoperative complications did not differ between groups apart from a higher observed incidence of seroma in the self-adhering mesh group (p=0.04). No hernias recurred in either group during the study interval. Self-adhering mesh in laparoscopic inguinal herniorrhaphy resulted in less immediate postoperative pain than tacked mesh as demonstrated by VAS score. Postoperative complications were similar between the two groups. The results of this study demonstrate that laparoscopic inguinal herniorrhaphy using self-adhering mesh is comparable to tacked mesh in regards to short-term complication rates, but show a favorable advantage in regards to immediate postoperative pain.

Bladder Fill after Laparoscopic Inguinal Hernia Repair Reduces Time to Discharge

Laparoscopic inguinal herniorrhaphy (LIH) has a relatively high risk of urinary retention. Bladder dysfunction may delay discharge after LIH. We hypothesized that filling the bladder before Foley catheter removal decreases time to discharge (TTD) after LIH. A secondary aim was to determine incidence of postoperative urinary retention (POUR) after bladder fill (BF). We reviewed a consecutive series of total extraperitoneal and transabdominal preperitoneal LIH procedures performed by a single surgeon at our institution from 2010 to 2013. All patients were catheterized during LIH, and selected patients received a 200-mL saline BF before Foley catheter removal. Patients were required to void >250 mL before discharge. TTD and incidence of POUR were compared between the BF and no-BF groups. A total of 161 LIH cases were reviewed. BF was performed in 89/161 (55%) of cases. TTD was significantly shorter in the BF versus the no-BF group (222 vs 286 minutes, respectively; P < 0.01). Patient and operative characteristics were similar between the BF and no-BF groups (P > 0.05). Incidence of POUR in the BF and the no-BF group was 10.1 and 16.7 per cent, respectively; however, this difference was not significant (P = 0.22). No postoperative urinary tract infection occurred in either group. In conclusions, postoperative BF significantly reduces TTD after LIH. Further studies may help to determine whether shorter postanesthesia care unit time and lower POUR rates associated with BF can lower LIH procedural costs and increase patient satisfaction.
