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.

The optimal surgical approach of incarcerated and strangulated inguinal hernia is controversial. Retrospective studies showed that surgical approaches through lower abdominal median incision or laparoscopic are superior to the oblique inguinal incision, respectively. Whether transabdominal laparoscopic approach is superior to the lower abdominal median incision approach needs prospective research.Prospective comparative study of patients with incarcerated and strangulated groin hernia admitted to Jinshan hospital for emergency surgery from January 2018 to June 2022. They were divided into two groups according to different surgical approach. The open preperitoneal repair group (OPR) was operated through the lower abdominal median incision. Laparoscopic preperitoneal repair group (TAPP) was completed under transabdominal laparoscope. The perioperative complications and long-term results of the two groups were compared and analyzed. Eighty-two patients met the inclusion criteria, 40 in OPR group and 42 in TAPP group. Baseline data of the two groups were comparable. Thirteen cases (15.9%) of the two groups underwent intestinal resection and anastomosis. Seventy cases (90.2%) underwent the 1st stage mesh repair, including 5 cases of preperitoneal hernioplasty after intestinal resection. The average operation time of TAPP group was 13 min longer (60.7 ± 13.7 min vs 47.8 ± 19.8 min P < 0.001), and the visual analogue scale pain score at 24 h after operation was lower (3.5 ± 1.2 vs 4.4 ± 1.7 P = 0.019) than that of OPR group. There was 1 case of bladder injury (2.5%) in OPR group and 1 case of inferior abdominal artery injury (2.4%) in TAPP group. There was no difference in the rate of the 1st stage hernioplasty between the two groups. In OPR group, 2 cases (5%) extended the incision for more than 2 cm, while in TAPP group, 1 case (2.4%) converted to laparotomy. The time of hospital stay (3.2 ± 1.8 d vs 4.3 ± 2.7 d, P = 0.036) and return to normal activities (7.9 ± 2.7 d vs 11.0 ± 4.4 d, P < 0.001) were shorter in TAPP group. The rate of total postoperative complications including chronic pain, surgical-site infection, seroma, hernia recurrence and so on was 11.9% in TAPP group, which was not significantly different from 25% in OPR group (P = 0.212). There were no cases of mesh related infection and death within 30 days in both groups.TAPP is safe and feasible for the operation of acute incarcerated inguinal hernia. TAPP had better comfort and faster recovery over open preperitoneal repair for the appropriate patients with incarcerated/strangulated inguinal hernia, which can reduce acute pain, shorten hospital stay and return to normal activities earlier.

BACKGROUND: Inguinal hernia develops as one of the common complications after robotic or laparoscopic radical prostatectomy (RP). Transabdominal preperitoneal patch plasty (TAPP) for an inguinal hernia after RP is difficult to perform due to postoperative severe adhesions in the preperitoneal cavity. We have introduced a high peritoneal incision approach (HPIA) in TAPP for inguinal hernia patients in whom peritoneal dissection is difficult due to severe adhesions after RP. We evaluate the safety and efficacy of TAPP with a HPIA for patients with an inguinal hernia after robot-assisted RP (RARP).
METHODS: Patients characteristics and surgical outcome were evaluated by a retrospective analysis.
RESULTS: From January 2014 to December 2017, 21 consecutive patients underwent TAPP for an inguinal hernia after RARP. Twenty-four lesions were the type 3b and three were type 3a according to the Nyhus classification. A circular incision TAPP was performed for 10 hernia lesions in eight patients and TAPP with HPIA was utilized for 17 lesions in 13 patients. The mean operation time for the unilateral hernia in the HPIA (137.8 ± 20.7 min) was significantly shorter than that (182.2 ± 42.0 min) in the circular incision TAPP (p = .038). The HPIA was complete in all patients, while the circular incision TAPP was converted to intraperitoneal onlay mesh (IPOM)intraperitoneal onlay mesh in five patients (55.6%, p = .008) due to dense adhesions with difficult dissection. No recurrent was observed after follow-up period of 48 months in both groups.
CONCLUSIONS: The TAPP with HPIA is feasible and a safe and reliable treatment of choice in patients with an inguinal hernia after RARP.

BACKGROUND: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.

This study aims to explore the safety and efficacy of 3D laparoscopy in elderly patients undergoing transabdominal preperitoneal (TAPP) surgery for inguinal hernia. Patients were divided into two groups based on the laparoscopic equipment used during surgery. Clinical data preoperatively, intraoperatively, and postoperatively were collected and subjected to statistical analysis. From January 2020 to August 2023, a total of 127 patients with primary unilateral inguinal hernia were evaluated in this study, 61 in the 3D TAPP group and 66 in the 2D TAPP group. There were no statistically significant differences in baseline data, including average age, gender distribution, BMI index, hernia type, hernia defect size and location, comorbidities, and usage of anticoagulant drugs between the two groups (P > 0.05). In terms of operative indicators, the 3D group showed shorter mean operation time (51.61 ± 7.16 min vs. 78.59 ± 13.51 min, P < 0.001), mean mesh placement time (6.07 ± 1.40 min vs. 9.77 ± 1.21 min, P < 0.001), and mean peritoneal suture time (7.34 ± 1.85 min vs. 9.73 ± 1.32 min, P < 0.001) compared to the 2D group. However, there were no statistically significant differences in mean blood loss, postoperative pain scores, postoperative hospital stay, and total hospital costs between the two groups (P > 0.05). The incidence of postoperative complications did not differ significantly between the two groups (P > 0.05). No adverse reactions such as dizziness or nausea were reported by surgeons during the procedures in either group. Three-dimensional laparoscopy in TAPP surgery provides high-definition, three-dimensional surgical images, reducing the difficulty of operations and effectively shortening the operation time.

OBJECTIVE: The transinguinal preperitoneal (TIPP) technique is an open approach to groin hernia repair with posteriorly positioned mesh supposed to reduce recurrence rates. However, transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) techniques have similar mesh positioning with the advantages of minimally invasive surgery (MIS). Hence, we performed a systematic review and meta-analysis comparing TIPP and MIS for groin hernia repair.
METHODS: Cochrane, Embase, Scopus, Scielo, and PubMed were systematically searched for studies comparing TIPP and MIS techniques for groin hernia repair. Outcomes assessed were recurrence, chronic pain, surgical site infection (SSI), seroma, and hematoma. We performed a subgroup analysis of TAPP and TEP techniques separately. Statistical analysis was performed with R Studio.
RESULTS: 81 studies were screened and 19 were thoroughly reviewed. Six studies were included, of which two compared TIPP with TEP technique, two compared TIPP with TAPP, and two compared TIPP with both TEP and TAPP techniques. We found lower recurrence rates for the TEP technique compared to TIPP (0.38% versus 1.19%; RR 2.68; 95% CI 1.01 to 7.11; P = 0.04). Also, we found lower seroma rates for TIPP group on the overall analysis (RR 0.21; P = 0.002). We did not find statistically significant differences regarding overall recurrence (RR 1.6; P = 0.19), chronic pain (RR 1.53; P = 0.2), SSI (RR 2.51; P = 0.47), and hematoma (RR 1.29; P = 0.76) between MIS and TIPP. No statistically significant differences were found in the subgroup analysis of TAPP technique for all the outcomes.
CONCLUSIONS: Our systematic review and meta-analysis found no differences between TIPP and MIS approaches in the overall analysis of recurrence, SSI, and chronic pain rates. Further research is needed to analyze individual techniques and draw a more precise conclusion on this subject.

OBJECTIVE: Annually, over 20 million patients worldwide undergo inguinal hernia repair procedures. Surgery stands as the recommended treatment, however, a consensus on the optimal method is lacking. This study aims to conduct an updated systematic review and meta-analysis to compare the risk of chronic inguinal pain and recurrence between laparo-endoscopic mesh repair (TAPP and TEP) versus Lichtenstein repair for inguinal hernia.
METHODS: Searches were conducted in Ovid MEDLINE, PubMed, EBSCO, Cochrane, and Google Scholar. Inclusion criteria encompassed randomized controlled trials (RCTs) involving adults, published in English and Spanish, comparing surgical outcomes among the Lichtenstein open technique, TAPP, and/or TEP. Adherence to the PRISMA guidelines was maintained in the methodology, and the CASP tool was employed to assess the quality of the articles. Statistical analysis involved mean [± standard deviation (SD)], Odds Ratio (OR), and Confidence Interval (CI).
RESULTS: Eight RCTs encompassing 1,469 patients randomized to Lichtenstein repair (n = 755) and laparo-endoscopic repair (n = 714) were included. Laparo-endoscopic repair was associated with a lower likelihood of chronic inguinal pain compared to Lichtenstein repair (OR = 0.28, 95% CI [0.30-0.56], p = 0.0001). There were no significant differences in recurrence rates between the laparo-endoscopic and the Lichtenstein group (OR = 1.03, 95% CI [0.57-1.86], p = 0.92).
CONCLUSIONS: This systematic review and meta-analysis demonstrate that laparo-endoscopic hernia surgery leads to a lower incidence of chronic inguinal pain compared to Lichtenstein repair, while maintaining similar rates of recurrence.

UNASSIGNED: Laparoscopic surgery is generally considered as better than open surgery in terms of less complications, minimal hospital stays and quick healing of the wounds. Our objective was to compare the immediate and early outcome of the different incarcerated hernias of anterior abdominal wall operated on as emergency cases by open and laparoscopic approach.
UNASSIGNED: This is a retrospective comparative study which was conducted at two hospitals of AlAhsa city of the Eastern region of the Kingdom of Saudi Arabia from July, 2017 to June, 2022. The data were retrieved from the medical records of the hospitals. All male and female patients having different types of incarcerated hernias of anterior abdominal wall presenting to the emergency room were included in the study. The patients were divided in two groups; those who were operated on by open approach (Group-I) and those who were operated on by laparoscopic approach (Group-II).
UNASSIGNED: Out of total 70 male and female patients, 42 were in Group-I and 28 in Group-II. The variety of the incarcerated hernias in both groups overall was para-umbilical 26(37.14%), incisional 18(25.71%), inguinal (right & left) 17(24.28%) and epigastric 9(12.86%). The mean operative time taken by Group I and II was 126.07 (±9.728) and 98.57 (±10.079) minutes respectively with a difference of 27.50 minutes (p=0.807). The mean hospital stay of the patients in Group I and II was 1.36(±0.719) and 1.57(±0.997) days respectively (p=0.482). The post-operative complications rate in Group-I was 6(14.28%) and in Group-II, 6(21.43%) (p=0.658). Overall, 12(17.14%) patients developed the complications in both groups. When the number of the complications is compared, it shows that there was no significant difference between the two groups (p=0.583).
UNASSIGNED: Laparoscopic approach is not superior to the open approach in the terms of the immediate and early outcome/complications of the incarcerated hernias of the anterior abdominal wall operated as emergency cases in this study.

UNASSIGNED: 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).
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.

Hernia recurrence is a common complication after inguinal hernia repair. Recent studies suggest that laparoscopic mesh repair with closure of direct hernia defects can reduce recurrence rates. Our study examines the effectiveness of this approach. A retrospective, multi-center cohort study was conducted on cases performed from January 2013 to April 2021. Patients with direct inguinal hernias (M3 according to EHS classification) undergoing TAPP were included. Three groups were present: closed-defect group, non-closed placing a standard-sized mesh group or non-closed placing an XL-sized mesh group. A 2-year follow-up was recorded. A total of 158 direct M3 inguinal hernias in 110 patients who underwent surgery were present. After propensity score matching at a 1:1 ratio, 22 patients for each group were analyzed. The mean age of patients was 62 years (41-84); with the majority being male (84.8%). 22 patients (40 hernias) underwent closure of the defect; 22 patients (39 hernias) did not undergo closure and used a standard-sized mesh; 22 patients (27 hernias) did not undergo closure and used an XL-sized mesh. There were 5 recurrences at 1 year post-operatively: all in the non-closure group with standard-sized mesh. This difference was statistically significant (p = 0.044). There were 7 recurrences (6.6%) at 2 years post-operatively: 6 in the non-closure group with standard-sized mesh and 1 in the non-closure group with XL-sized mesh (p = 0.007). Closing large direct inguinal hernia defects has shown promise in reducing early recurrence rates. However, conducting larger RCTs in the future could provide more conclusive evidence that might impact the way we approach laparoscopic inguinal hernia repair.
