A Comparative Study of Tackers Versus Sutures in Transabdominal Preperitoneal Hernia Repair: Tackers Versus Sutures in Mesh Fixation and Peritoneal Closure in Tapp

Background: This study evaluates the surgical outcomes of using tackers versus sutures for mesh fixation and peritoneal closure in transabdominal preperitoneal (TAPP) mesh repair of inguinal hernia, focusing on postoperative pain, quality of life, and other key metrics. Although there are many studies in studying various outcomes of Transabdominal preperitoneal mesh repair (TAPP), there exists only few trials that compare peritoneal closure techniques in TAPP Methods: A prospective comparative study was conducted at Mahatma Gandhi Medical College and Research Institute. Sixty patients undergoing TAPP were divided into two groups: one using non-absorbable sutures and the other using non-absorbable titanium tackers for mesh fixation and peritoneal closure. Intraoperative and postoperative outcomes were assessed, including time taken for procedures, postoperative pain (measured using the Visual Analog Scale), incidence of seroma formation, and short-term quality of life assessed using the Carolinas Comfort Scale. Results: The suture group demonstrated significantly less postoperative pain on postoperative day (POD) 1 and at 3 months compared to the tacker group (p=0.001 and p=0.004, respectively). The time taken for mesh fixation and peritoneal closure was shorter in the tacker group, but the overall operative time was significantly longer in the suture group (p=0.001). The cost of using sutures was substantially lower than tackers. Quality of life scores at 3 months indicated better outcomes in the suture group (p=0.001). Conclusions: Sutures for mesh fixation and peritoneal closure in TAPP repair provide better postoperative outcomes in terms of pain, quality of life, and cost compared to tackers, despite a longer operative time. These findings suggest that sutures may be a preferable option for TAPP inguinal hernia repair.

Optimizing Urological Concurrent Robotic Multisite Surgery: Juxtaposing a Single-Center Experience and a Literature Review.

Introduction: This article juxtaposes case series with a systematic review to evaluate the feasibility, safety, and clinical outcomes of concurrent robotic multisite urological surgeries, specifically robot-assisted radical prostatectomy (RARP) and robot-assisted partial nephrectomy (RAPN), for synchronous prostate and kidney cancers. Aim: The aims of this study were to evaluate the feasibility, safety, and clinical outcomes of urological concurrent robotic multisite surgeries through a comparison of institutional findings with the existing literature. Materials and Methods: A retrospective analysis was conducted on eight institutional cases of concurrent robotic multisite surgeries performed between 2021 and 2024. The primary outcomes measured were operative time, blood loss, and postoperative complications. A systematic review of the literature was performed, searching PubMed, Embase, and Cochrane Library databases, with the last search conducted on 1 July 2024. Studies were included if they reported on concurrent robotic surgeries corresponding to the procedures performed at the institution, including RARP with RAPN, RARP with robotic transabdominal preperitoneal inguinal hernia repair (RTAPPIHR), and other multisite robotic surgeries. Risk of bias was assessed using the modified Newcastle-Ottawa Scale. Descriptive statistics were used to analyze operative time and blood loss, with confidence intervals (CIs) calculated to assess precision. Categorical variables, including postoperative complications, were summarized using frequencies and percentages. Heterogeneity was assessed using the I2 statistic, with values above 50% indicating substantial heterogeneity. A random effects model was applied when necessary, and sensitivity analyses excluded studies with high risk of bias. Results: We describe a unique docking technique employed in our procedures, which allows for atraumatic transitions between surgeries using the same port sites. Our institutional cases demonstrated the feasibility and safety of concurrent robotic multisite surgery, with a mean operative time of 315 min (95% CI: 290-340) and mean blood loss of 300 mL (95% CI: 250-350). There were no significant intraoperative complications reported. These findings are consistent with the literature, where mean operative times range from 390 to 430 min and blood loss ranges from 200 to 330 mL. Notably, no positive surgical margins or declines in postoperative renal function were observed in our cases. The systematic review included nine retrospective studies involving 40 cases of concurrent RARP and RAPN, as well as eleven studies including 392 cases of RARP combined with RTAPPIHR. The findings from these studies support the feasibility and safety of concurrent surgeries, showing similar rates of operative time, blood loss, and postoperative complications. Conclusions: Concurrent robotic multisite surgeries, such as RARP combined with RAPN or RTAPPIHR, appear to be safe and feasible. Our data suggest these procedures are non-inferior to separate surgeries in terms of safety and complication rates. Potential benefits, including reduced operative times, shorter hospital stays, and more efficient resource use, may translate into cost savings, although no formal cost-effectiveness analysis was conducted. Limitations include the small sample size, retrospective design, and lack of long-term follow-up. Prospective trials are needed to validate these findings and further refine the techniques. Funding: this review did not receive any external funding. Registration: this review was not registered in any public protocol registry due to its comparative retrospective nature.

Is previous radical prostatectomy a contraindication to minimally invasive inguinal hernia repair? A contemporary meta-analysis.

Traditionally, radical prostatectomy (RP) has been considered a contraindication to minimally invasive inguinal hernia repair. Purpose of this systematic review was to examine the current evidence and outcomes of minimally invasive inguinal hernia repair after RP. Web of Science, PubMed, and EMBASE data sets were consulted. Laparoscopic transabdominal preperitoneal repair (TAPP), robotic TAPP (r-TAPP), and totally extraperitoneal (TEP) repair were included. Overall, 4655 patients (16 studies) undergoing TAPP, r-TAPP, and TEP inguinal hernia repair after RP were included. The age of the patients ranged from 35 to 85 years. Open (49.1%), laparoscopic (7.4%), and robotic (43.5%) RP were described. Primary unilateral hernia repair was detailed in 96.3% of patients while 2.8% of patients were operated for recurrence. The pooled prevalence of intraoperative complication was 0.7% (95% CI 0.2-3.4%). Bladder injury and epigastric vessels bleeding were reported. The pooled prevalence of conversion to open was 0.8% (95% CI 0.3-1.7%). The estimated pooled prevalence of seroma, hematoma, and surgical site infection was 3.2% (95% CI 1.9-5.9%), 1.7% (95% CI 0.9-3.1%), and 0.3% (95% CI = 0.1-0.9%), respectively. The median follow-up was 18 months (range 8-48). The pooled prevalence of hernia recurrence and chronic pain were 1.1% (95% CI 0.1-3.1%) and 1.9% (95% CI 0.9-4.1%), respectively. Minimally invasive inguinal hernia repair seems feasible, safe, and effective for the treatment of inguinal hernia after RP. Prostatectomy should not be necessarily considered a contraindication to minimally invasive inguinal hernia repair.

Comparison of postoperative chronic inguinal pain between the lichtenstein and laparoscopic techniques in the treatment of inguinal hernia: a systematic review and meta-analysis.

Currently, inguinal hernias are highly prevalent in the Brazilian population, accounting for 75% of all abdominal wall hernias. The recommended treatment to correct them is inguinal herniorrhaphy, which can be performed through open surgery, mainly using the Lichtenstein technique, or laparoscopically, primarily through Transabdominal Preperitoneal Repair (TAPP) or Total Extraperitoneal Repair (TEP) approaches. Like any surgery, these procedures have post-operative complications, with pain being the most common and debilitating. Currently, in European and Brazilian guidelines, the open Lichtenstein and endoscopic inguinal hernia techniques are recommended as best evidence-based options for repair of a primary unilateral hernia providing the surgeon is sufficiently experienced in the specific procedure. In that matter, the surgeon should make a choice based on assessment of the benefits and risks of performing each of them, and practice shared making decision with it patient. Therefore, the objective of this review was to assess the incidence of chronic postoperative pain by comparing the aforementioned surgical approaches to evaluate which procedure causes less disability to the patient. The search conducted untilMay 2024 was performed on Medline (PubMed), Cochrane (CENTRAL), and Lilacs databases. The selection was limited to randomized clinical trials, nonrandomized clinical trials and cohort studies comparing TAPP or TEP to LC, evaluating the incidence of chronic postoperative pain published between 2017 and 2023. Evidence certainty was assessed using the GRADE Pro tool, and bias risk was evaluated with the RoB 2.0 tooland ROBINS I tool. Thirteen studies were included. RESULTS: The meta-analysis showed a significant difference between the groups in both techniques, favoring the laparoscopic approach, which had a lower occurrence of postoperative inguinodynia with a relative risk of 0.49 (95% CI = 0.32, 0.75; I2 = 66% (P = 0.001); Z = 3.28 (P = 0.001) with low certainty of evidence. The presence of chronic postoperative pain was lower in laparoscopic TEP/TAPP techniques when compared to the open Lichtenstein technique, meaning that the former can bring more benefits to patients who requires inguinal herniorrhaphy. Nevertheless, further randomized clinical trials are needed to optimize the analysis, minimizing the bias.

Effect of Laparoscopic Inguinal Hernia Repairs on Inflammatory Factors, Oxidative Stress Levels and Postoperative Recovery.

To unravel the effects of different laparoscopic inguinal hernia repairs (IHRs) on inflammatory factors, oxidative stress, and postoperative recovery of inguinal hernia (IH) patients. A total of 88 patients for laparoscopic treatment of IH were studied in a retrospective cohort, and were randomized into the transabdominal preperitoneal (TAPP) repair group (n = 44) and the total extraperitoneal (TEP) repair group (n = 44) according to the method of treatment. Patients in the TAPP group underwent laparoscopic TAPP IHR, while patients in the TEP group underwent laparoscopic TEP IHR. Visual analogue scores (VAS) were measured at 1, 3, and 7 d after repair. Gastrin (GAS), motilin (MTL), matrix metalloproteinase (MMP)-2, MMP-9, and tissue inhibitor of metalloproteinases-1 (TIMP-1) were assessed by enzyme-linked immunosorbent assay. Superoxide dismutase (SOD) was tested by spectrophotometry and malondialdehyde (MDA) and β-endorphin (β-EP) were examined by radioimmunoprecipitation. Total antioxidant capacity (T-AOC) was evaluated by chemical colorimetry, quality of life was evaluated by SF-36, and fibrinogen (FIB), C-reactive protein (CRP), antitrypsin (al-AT), and interleukin-6 (IL-6) levels were determined by immunoturbidimetry. Complications and postoperative recurrence were recorded. VAS scores in the TEP group were lower than those in the TAPP group. Operative time, hospital stay, time for postoperative activity out of bed, and time taken to exhaust were shorter in the TEP group than in the TAPP group. Intraoperative blood loss was less in the TEP group than in the TAPP group. GAS, MTL, SOD, and T-AOC were higher, and MDA, β-EP, CRP, FIB, alAT, IL-6, MMP-2, MMP-9, and TIMP-1 were lower in the TEP group than the TAPP group. Quality of life was improved in the TEP group compared with the TAPP group. There was no significant difference in the rate of postoperative complications and recurrence rates between both groups of patients. For IHs, laparoscopic TEP repair can effectively relieve pain, reduce inflammatory factors and oxidative stress indices, and facilitate postoperative recovery.

Laparoscopic transabdominal preperitoneal repair for a patient with Laugier’s and inguinal hernia

BackgroundLaugier’s hernia is a very rare atypical femoral hernia and is challenging to diagnose preoperatively. Herein, we report a rare case of inguinal and Laugier’s hernias treated with laparoscopic transabdominal preperitoneal repair.Case presentationA 63-year-old man was admitted to our hospital with right groin swelling for 4 years. Computed tomography revealed an indirect inguinal hernia with protrusion of the small intestine. The preoperative diagnosis was right indirect inguinal hernia; Laugier’s hernia was unknown. The patient underwent laparoscopic transabdominal preperitoneal repair. During the surgery, part of the perivesical adipose tissue penetrated the lacunar ligament. It was located medial to the typical site of a femoral hernia. Thus, Laugier's hernia was diagnosed. Finally, laparoscopic transabdominal preperitoneal repair was performed for Laugier's hernia and inguinal hernia. The postoperative course was good, without recurrence.ConclusionsTo our knowledge, this is the first reported case of inguinal and Laugier’s hernia treated with laparoscopic transabdominal preperitoneal repair. Surgeons should be mindful that inguinal hernias can occur concurrently with other types of hernias, such as femoral hernias, including atypical variants like Laugier's hernia. Additionally, they should actively consider laparoscopic approaches such as transabdominal preperitoneal for femoral hernias. These approaches are beneficial for precise diagnosis, confirming the presence of other hernias, and simultaneously treating all coexisting inguinal hernias.

A single-center retrospective review of laparoscopic totally extraperitoneal versus robotic transabdominal preperitoneal inguinal hernia repair

Background With the increased use of robotic surgery, robotic transabdominal preperitoneal repair (R-TAPP) has become a commonly used approach for inguinal hernia repair. The laparoscopic totally extraperitoneal repair (L-TEP) has the advantage of not entering the peritoneal cavity; however, it has greater technical difficulty. Robotic surgery has demonstrated superiority over laparoscopy in many surgical settings, but there is limited evidence comparing L-TEP and R-TAPP. Methods This was a retrospective review of patients who underwent L-TEP and R-TAPP at Baylor University Medical Center between December 2011 and January 2022. Information on patient demographic characteristics, comorbidities, postoperative complications, hospital length of stay, and postoperative complications requiring a procedure was collected. Results A total of 298 patients were analyzed; 245 underwent R-TAPP and 53 underwent L-TEP. Hernia recurrence was significantly decreased in those who underwent R-TAPP (1.2%) compared to L-TEP (9.4%) (P = 0.01). Postoperative pain was also significantly decreased in the R-TAPP group (5.3%) as compared to the L-TEP group (13.2%) (P = 0.01). Conclusions With the transition from L-TEP to R-TAPP over recent years, there is limited evidence supporting this change in practice. Our single-center retrospective review demonstrates that R-TAPP is noninferior to L-TEP and has significantly decreased hernia recurrence.

Assessment of Three Distinct Approaches to Postoperative Pain in Laparoscopic Inguinal Hernia Repair, a Randomized Prospective Study.

Background: Contemporarily, transabdominal preperitoneal repair (TAPP) procedure in inguinal hernia treatment is counted among the routine minimal invasive general surgery practices. Increased patient's comfort, namely less postoperative pain, is considered to be its greatest advantage. However, pain following surgery can still be an important problem. Port site local anesthetic injection (PSLAI), iliohypogastric-/ilioinguinal nerve block (IINB), and preperitoneal local anesthetic spraying (PLAS) are relatively new techniques with sparse data to address this issue. Therefore, we conducted this prospective study to evaluate these three methods in patients who underwent TAPP for inguinal hernia repair. Methods: A total of 99 patients were enrolled and randomized equally into three groups. Every patient received a patient-controlled analgesia (PCA) device. PCA usage, total analgesic demands, and numerical rating scale values were recorded at 2, 6, 12, and 24 hours postoperatively (p.o). Results: Patients' demographic data (age, gender, BMI) did not reveal any significant difference between groups (P > .05). Procedure duration was found to be significantly longer in IINB group compared with others (p < .05). Number of PCA usages, total analgesic demand, additional analgesic requirement did not differ significantly between groups at 24-hour p.o (P > .05). PLAS group was found to have less average NSR score compared with other groups at 24 hours p.o (p < .05). Conclusions: All three procedures show promising outcomes with PLAS technique appearing to be slightly superior in terms of pain management in the immediate postoperative period. However, to reach a conclusion more randomized controlled trials covering various aspects and techniques of minimal invasive approach to inguinal hernia repair should be published.

Suture versus tacks in minimally invasive transabdominal preperitoneal inguinal repair: a meta-analysis of randomized controlled trials.

There is uncertainty regarding the method of mesh fixation and peritoneal closure during transabdominal preperitoneal (TAPP) repair for inguinal hernias, with no definitive guidelines to guide surgeon choice. MEDLINE, Cochrane, Central Register of Clinical Trials, and Web of Science were searched for RCTs published until November 2023. Risk ratios (RRs) and mean differences (MD) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p values inferior to 0.10 and I2 > 25% considered significant. Statistical analyses were conducted using Review Manager version 5.4 and RStudio version 4.1.2 (R Foundation for Statistical Computing). Eight randomized controlled trials (RCTs) were included, comprising 624 patients, of whom 309 (49.5%) patients were submitted to TAPP with the use of tacks, and 315 (50.5%) received suture fixation. The use of tacker fixation was associated with a significant increase in postoperative pain at 24h (MD 0.79 [VAS score]; 95% CI 0.38 to 1.19; p < 0.0002; I2 = 87%) and one week (MD 0.42 [VAS score]; 95% CI 0.05 to 0.79; p < 0.03, I2 = 84%). The use of tacks was associated with shorter operative time (MD-25.80 [min]; 95% -34.31- -17.28; P < 0.00001; I2 = 94%). No significant differences were found in overall complications, chronic pain, seromas, hematomas, and urinary retention rates. In patients who underwent TAPP hernia repair, tacks are associated with decreased operative time but increased postoperative pain at 24h and one week.

Short-term outcomes and inflammatory stress response following laparoscopy or robotic-assisted transabdominal preperitoneal inguinal hernia repair (TAPP): study protocol for a prospective, randomized trial (ROLAIS)

BackgroundInguinal hernia repair is a frequently performed surgical procedure, with laparoscopic repair emerging as the preferred approach due to its lower complication rate and faster recovery compared to open repair. Mesh-based tension-free repair is the gold standard for both methods. In recent years, robotic hernia repair has been introduced as an alternative to laparoscopic repair, offering advantages such as decreased postoperative pain and improved ergonomics.This study aims to compare the short- and long-term outcomes, including the surgical stress response, postoperative complications, quality of life, and sexual function, between robotic-assisted transabdominal preperitoneal (rTAPP) and laparoscopic TAPP inguinal hernia repairs.MethodsThis randomized controlled trial will involve 150 patients from the Surgical Department of the University Hospital of Southern Denmark, randomized to undergo either rTAPP or laparoscopic TAPP. Surgical stress will be quantified by measuring C-reactive protein (CRP) and cytokine levels. Secondary outcomes include complication rates, quality of life, sexual function, and operative times. Data analysis will adhere to the intention-to-treat principle and will be conducted once all patient data are collected, with outcomes assessed at various postoperative intervals.DiscussionThis study holds significance in evaluating the potential advantages of robotic-assisted surgery in the context of inguinal hernia repairs.It is hypothesized that rTAPP will result in a lower surgical stress response and potentially lower the risk of postoperative complications compared to conventional laparoscopic TAPP. The implications of this research could influence future surgical practices and guidelines, with a focus on patient recovery and healthcare costs. The findings of this study will contribute to the ongoing discourse surrounding the utilization of robotic systems in surgery, potentially advocating for their broader implementation if the benefits are substantiated.Trial registrationClinicalTrials.gov NCT05839587.

Retrospective analysis of transabdominal preperitoneal hernia repair in emergency cases: A cohort study.

This study aimed to evaluate the feasibility, safety, and efficacy of laparoscopic transabdominal preperitoneal hernia repair (TAPP) for inguinal hernias in emergency settings, providing insights from a long-term follow-up. We retrospectively analyzed all patients who underwent emergency TAPP repair in ASST Nord Milano from January 2005 to December 2023. A prospectively collected database of 54 consecutive TAPP hernia repairs was reviewed. The study evaluated the feasibility and safety of TAPP through operative time and the conversion rate. Effectiveness was gauged by recurrence and complication rates as well as acute and chronic pain using the Visual Analog Scale (VAS). Long-term follow-up included assessing recovery to normal activity. Overall, data from 54 consecutive patients were analyzed. Median age was 72 (IQR=11), with 21 men and 33 women (38.8% vs. 61.2%). The primary diagnosis was a primary hernia (61.1%), while a recurrent type was identified in 21 patients (38.9%). Femoral hernia was identified in 36 cases (48%). The median operative time was 100min (IQR=53min) with 6 cases of conversion (11.1%). One recurrence (1.85%) was noted and the complication rate was 5.55 %. At a median follow-up of 38months, there was a low grade of chronic pain (VAS 3) in a patient (1.85%) and one recurrence (1.85%). TAPP is a safe, feasible, and effective option for emergency inguinal hernia repair, exhibiting low complication and recurrence rates on long-term follow-up when performed by surgeons with minimally invasive surgery experience and in selected patients.

Initial experience of SSI Mantra robot-assisted Transabdominal pre-peritoneal repair of primary ventral hernias.

Small and medium sized primary midline ventral hernias are best treated by pre-peritoneal mesh placement. This helps in prevention of complications related to intra-peritoneal mesh placement. The challenges we face while performing laparoscopic transabdominal pre-peritoneal (TAPP) procedure can be overcome by robot-assisted TAPP (rTAPP), and we present our initial experience with the same. We describe the surgical technique used in rTAPP using the relatively new SSI Mantra platform for primary midline ventral hernia repair and evaluate its feasibility and present the outcomes. we performed rTAPP for primary midline ventral hernia repair in 10 patients from July 2023 to September 2023. Demographic patient data, hernia characteristics and peri-operative outcomes were measured. A total of 10 patients underwent elective rTAPP for primary midline ventral hernia, of which 7 were male and 3 were female. The average defect size was 3.2 cm. The average operative time was 113 min. All the patients were discharged within 24-36 h after the procedure. There were no deaths. No post-operative complications such as haematoma, clinically significant seroma, deep or superficial wound infection or recurrence were noted within 30 days. rTAPP is a technically feasible procedure for the repair of small- and medium-sized midline ventral hernias with defect sizes up to 5 cm. SSI Mantra robotic platform provides the same benefit that other conventional robotic platforms provide at a much lesser cost. Further studies looking at the cost-benefit ratio are required to substantiate the above.

Robotic assisted extended view totally extraperitoneal repair for inguinal hernia

Robotic assisted transabdominal pre-peritoneal inguinal hernia repair is an effective and safe approach. This report describes a new technique of robotic extended view totally extraperitoneal repair. A supraumbilical retro rectus approach, creation of pre-peritoneal space, separation of hernia sac from cord structures, placement of mesh and fixing with vicryl suture was employed in a 58-year gentleman with right inguinal hernia. The surgery was performed with the use of a DaVinci robotic system. No intraoperative problems were encountered. The patient was discharged within 24 hours of surgical intervention. The work has been reported in line with the SCARE criteria. The patient had no groin pain, inguinal or scrotal swelling at 30 day follow up. He was pleased with the cosmetic result and has gone back to work. Robotic e-TEP is a viable option in inguinal hernia repair.

Development and validation of a high-quality simulator with exchangeable peritoneum for transabdominal preperitoneal laparoscopic inguinal hernia repair.

Practical simulation training with proper haptic feedback and the fragility of the human body is required to overcome the long learning curve associated with laparoscopic inguinal hernia repair (LIHR). However, few hernia models accurately reflect the texture and fragility of the human body. Therefore, in this study, we developed a novel model for transabdominal preperitoneal (TAPP) LIHR training and evaluated its validity. We developed a high-quality mock peritoneum with a hydrated polyvinyl alcohol layer and a unique two-way crossing cellulose fiber layer. To complete the simulation, the peritoneum was adhered to a urethane foam inguinal base with surgical landmarks. Participants could perform all the procedures required for the TAPP LIHR. Twenty-four surgeons performed TAPP LIHR simulation using a novel simulator. Their opinions were rated on a 5-point Likert scale. Additionally, 6 surgical residents and 10 surgical experts performed the procedure. Their performance was evaluated using the TAPP checklist score and procedure time. Most participants strongly agreed that the TAPP LIHR simulator with an exchangeable peritoneum model was useful. The participants agreed on the model fidelity for tactile sensation, forceps handling, and humanlike anatomy. In comparisons between surgical residents and experts, the experts had significantly higher scores (10.6 vs. 17.2, p < 0.05) and shorter procedure times (92.3 vs. 55.9 min; p < .05) than did surgical residents. We developed a high-quality exchangeable peritoneal model that mimics the human peritoneum's texture and fragility. This model enhances laparoscopic simulation training, potentially shortening TAPP LIHR learning curves.

A comparative study on effects of defect closure versus non-closure in laparoscopic totally extraperitoneal repair of direct inguinal hernia.

Totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) repair are the principal techniques in laparoscopic hernia repair. Seroma formation and pain are frequent complications of moderate-large size laparoscopic direct inguinal hernia mesh repair. This study was conducted to evaluate the feasibility of defect closure in moderate-large direct inguinal hernias and its effect on various outcomes. This is a prospective cohort study from September 2020 to August 2021, where a total of 88 patients with uncomplicated direct inguinal hernia (M3 or more) were enrolled in the study and divided into two equal groups of TEP defect closure and non-closure, and various outcome measures were noted. The majority of patients were male (94.31%), with a mean age range of 18-85 years, and had right-sided inguinal hernia (46.5%). Seroma formation at 10th POD in the defect closure and non-closure were 24% and 33% (p value: 0.225), which reduced to 11% and 18%, respectively, at 1 month (p value: 1.000). All seromas resolved within 6 months. Pain in VAS at 10th POD in the defect closure and non-closure were 1.55±0.571 and 1.38±0.527, respectively (p value: 0.121), which gradually decreased to 1.20±0.524 and 1.16±0.420 at a 6-month interval (p value: 0.689). The mean operative time in the bilateral and unilateral defect closure groups was 72.3±4.1 and 56.5±4.3 min, respectively, whereas that in the bilateral and unilateral defect non-closure groups was 62.3±3.7 and 45.7±3.6 min, respectively. The defect closure was found to have higher pain and less seroma formation at various intervals of time following TEP for moderate-large direct inguinal hernia. Although these findings were statistically insignificant, they may be clinically significant, and further studies with a larger sample size are suggested.

TEP or TAPP: who, when, and how?

Groin hernia repair is the most common procedure performed by general surgeons. The open mesh technique generally represents the main technique for an inguinal repair, but a different approach is often required. Laparoscopy was found to be the answer to minimizing the impact of the preperitoneal open techniques described by Nyhus and Stoppa. The introduction of the totally extraperitoneal hernia repair (TEP) and transabdominal preperitoneal repair (TAPP) in the early 1990s started a new chapter in groin hernia surgery. The minimally invasive techniques vs. open mesh, and then one against the other, soon became a hot topic among abdominal wall surgeons. With time, the number of procedures and indications increased and are still increasing. This review aims to provide an overview of the two main laparoscopic techniques for groin hernia repair, answering the following questions: Who should perform them? What is the learning curve required to minimize complications and optimize operative time? When is a minimally invasive approach indicated, and which one (both in elective and in emergency setting)? How are they performed? The standard techniques have been described in detail, and personal observations from an abdominal wall surgery referral center were added. The main reviews from the early 2000s up to date, which compared the techniques, were analyzed, and the results reported, confirming the comparable safety and efficacy of both these techniques.

ETEP-PP for repair of primary midline ventral hernias

Abstract BACKGROUND: Minimally invasive surgery for hernia repair has advanced significantly, with techniques such as transabdominal preperitoneal repair (TAPP) and totally extraperitoneal repair for inguinal hernias inspiring similar approaches for ventral and incisional hernias. The enhanced-view totally extraperitoneal repair (eTEP) technique, introduced in the twenty-first century, demonstrated advantages in inguinal hernia repair. Leveraging the benefits of eTEP and TAPP while addressing their limitations, we developed the extended totally extraperitoneal preperitoneal repair (eTEP-PP) technique for primary midline ventral hernias. This technique combines the benefits of eTEP and TAPP, avoids specific drawbacks such as the need to divide the posterior rectus sheath or close the peritoneum, and ensures safer and more effective repair. The eTEP-PP method shows promise as a future standard for small-to-medium primary ventral hernia repairs. Further studies are needed to confirm its long-term efficacy and application. MATERIALS AND METHODS: This retrospective study included 15 patients who underwent eTEP-PP surgery between February 2024 and June 2024 at the Department of Surgical Gastroenterology, Regency Hospital, Kanpur, Uttar Pradesh, India. Patients with primary midline ventral abdominal wall hernias were studied, noting intraoperative and postoperative outcomes. RESULTS: All 15 patients experienced no intraoperative complications or conversions to open surgery. Two patients required conversion from eTEP-PP to eTEP due to challenges in creating the preperitoneal flap. Postoperative outcomes were excellent, with no surgical site occurrences or complications requiring intervention. There were no readmissions, mortalities, or recurrences 1 month post-surgery. CONCLUSION: The eTEP-PP technique for primary ventral hernia repair is reproducible and has shown excellent initial outcomes. While the study’s sample size is a limitation, the technique’s potential as a future standard for small-to-medium primary ventral hernia repairs is evident. Further studies are needed to establish its long-term efficacy and broaden its application.

Comparative analysis of comorbidity, surgical complications, pharmacotherapeutic needs, and rehabilitation requirements in transabdominal preperitoneal hernia repair versus conventional operative treatment—current results and benefits

Background: Laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is a relatively new method of inguinal hernia surgical repair that, at theory, provides a good view of the inguinal anatomy and sac contents and, as a laparoscopic procedure, is considered less invasive and with fewer complications compared to total extraperitoneal (TEP) inguinal hernia repair. Purpose: This study aims to assess the short-term outcome of laparoscopic transabdominal preperitoneal inguinal hernia (TAPP) repair. Material and methods: The retrospective clinical data for 138 patients with unilateral and bilateral hernia, operated in the Department of General, Visceral, and Emergency Surgery of the University Emergency Medicine Hospital ‘N. Pirogov’ from 01 January 2022, to 01 January 2023, were included. The risk profile of the patients, the intraoperative and postoperative complications, the duration of hospital stay, the frequency, and the type of analgesics used were analyzed. Results: Forty-one women (29.7%) were included; men comprised 97 (70.29%) of the cohort. Of the selected group, 63 (45.7%) patients had indirect inguinal hernias, 34 (24.6%), and 25 (18.1%) were diagnosed with direct inguinal hernia and accreta inguinal hernia, respectively. A history of repeatedly occurring hernias was found in 16 patients (11.6%). The average hospital stay was 32 hours (or 1.3 days) and ranged from 24 hours (1 day) to 48 hours (2 days). Complications occurred in 11 (7.97%) patients. The need for analgesics and anti-inflammatory agents was reliably reduced compared to the patients undergoing conventional surgical treatment of inguinal hernia. The patients were followed for three months post-discharge for the occurrence of surgical morbidity associated with the TAPP hernia repair. None of the patients used an antimicrobial agent, as indicated by a possible complicating bacterial infection. Rehabilitation was started within the first 12 hours after the operation, thus contributing to a significantly shorter hospital stay compared to patients undergoing conventional surgical repair of an inguinal hernia. Conclusion: Our results demonstrate that TAPP inguinal hernia repair is a safe procedure with reduced postoperative pain. It has fewer complications, with no significantly longer operative time and a shorter overall hospital stay.

The initial experience of robot-assisted transabdominal transversalis fascial and preperitoneal repair for small ventral hernia.

Despite the widespread of ventral hernia repairs globally, the approach method, dissection planes, defect closure, and the choice and placement layer of mesh are an ongoing debate. We reported the details of surgical techniques, safety and feasibility for robot-assisted transabdominal transversalis fascial and preperitoneal repair (R-TATFPP) for small ventral hernia. This study included 5 cases of R-TATFPP repair among 22 cases performed by robot-assisted ventral hernia repair from 2018 to 2023 with the approval of the Institutional Review Board at St. Luke's International University and clinical ethical committee at St. Luke's International Hospital (19-R147, 22-012). There were four males and one female, with mean age of 64.4 ± 10.0 years, inclusive of two umbilical and three incisional hernias. Mean height, weight, body mass index (BMI), hernia defect length, width, operation time, console time, and hospital stay were 171.2 ± 11.8 cm, 82.4 ± 13.4 kg, 28.0 ± 2.1 kg/m2, 2.8 ± 1.4 cm, 3.0 ± 1.3 cm, 180 min, 133.8 min, and 2.4 days, respectively. No conversion nor complication was observed except for one acute urinary retention. Robot-assisted transversalis fascial and preperitoneal repair was safe and feasible for small ventral hernia with the minimal disruption to the abdominal wall architecture and structures.
