OBJECTIVE: 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.
METHODS: The search conducted until May 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 tool and 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.
CONCLUSIONS: 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.

UNASSIGNED: Inguinal hernia repair is the most frequent operation in general surgery. The chance of a person having to undergo an inguinal hernia operation during his/her life is quite high, 27 % in men and 3 % in women. European Hernia Society guidelines state that the Lichtenstein technique (mesh-based repair) is the standard treatment of elective inguinal hernia in adults. Some authors consider the Shouldice technique (tissue-based repair) the best conventional method for open hernia repair. In this study, we compared these two methods.
UNASSIGNED: In This randomized study, 452 patients were randomly allocated into 2 groups. 51 patients were lost during follow-up period and were excluded from further analysis in the study. Finally, the analyzed patients were 183 patients in Shouldice technique group and 218 patients in Lichtenstein technique group. All patients were examined after 1 week, 1, 3 months, 1, 2, and 3 years after the operation date.
UNASSIGNED: After 3 years follow up Recurrence of hernia in Shouldice technique group was 7.1 % and in Lichtenstein technique group was 3 % with significant differences (p-value 0.006). No statistically significant differences were found between the groups in wound infection, Seroma, hematoma, Hydrocele, Bladder damage, chronic pain in the inguinal region, and Patient Satisfaction level after surgery.
UNASSIGNED: It seems that inguinal hernia treatment by the Lichtenstein technique is better than the Shouldice technique in elective patients.

Inguinal bladder herniation (IBH) is an uncommon case, observed in only 1-5 % of all inguinal hernias. Obesity, the elderly, gender, and previous operations are vigorous determinants for IBHs. Symptoms depend on the size of the hernia. We report a case of an obese male aged 40 presenting with a bulge increasing gradually in the right groin with a history of two-stage micturition (Mery\'s sign). With imaging-assisted diagnosis modalities (US, CT, and MRI), the patient was diagnosed with IBH. Although IBH is not common, it should always be suspected in patients with Mery\'s sign and predisposing factors.

OBJECTIVE: The study aimed to evaluate sexual function before and after inguinal hernia surgery using a standard, internationally approved, patient-administered questionnaire.
METHODS: 57 male inguinal hernia cases operated with the Lichtenstein hernioplasty technique were prospectively included in the study. Patients who agreed to participate in the study had the IIEF (International Index of Erectile Function) scoring system form consisting of 15 questions filled in preoperatively, during the first and sixth months after surgery. Patients\' age, BMI, comorbidity, employment status, hernia type, hernia size, and single or bilateral hernia were recorded. The relationship between these variables was evaluated by statistical analysis.
RESULTS: A statistically significant difference was found in terms of erectile function, sexual desire, intercourse function, and overall satisfaction, when the preop-postop first month, preop-postop sixth month, and postoperative first month-postop six-month scores were compared (p < 0.05).
CONCLUSIONS: Pain and swelling due to an inguinal hernia can negatively affect the sexual functions of the patient, and most of the patients benefit from this after the surgery. Sexual dysfunction may be one of the indications for an inguinal hernia operation.

BACKGROUND: A modified Kugel patch is more expensive than ordinary mesh and demands a wide dissection of the preperitoneal space in femoral hernia repair. We therefore adopted a novel method using mini-mesh and a Lichtenstein repair. This study compared mini-mesh and Lichtenstein repair with a modified Kugel technique in patients with a primary unilateral femoral hernia.
METHODS: Patients with unilateral femoral hernia were assigned randomly to undergo mini-mesh and Lichtenstein repair (M group) or modified Kugel repair (K group), followed-up at one week, three months, one year and two years. Demographics, hernia characteristics and operative outcomes of two groups were analysed.
RESULTS: A total of 48 patients in the K group and 49 participants in the M group completed follow-up. The operation time for the M group (68.6 ± 13.4 minutes) was significantly shorter than that of the K group (80.6 ± 10.1 minutes; p=0.030). There was no significant difference between the two groups for chronic pain, foreign body feeling and quality of life, and no recurrence occurred.
CONCLUSIONS: Mini-mesh and Lichtenstein repairs have reasonable results in the patients with femoral hernia in this study, with a reduced operation time compared with a modified Kugel repair. The trial was registered with the Chinese Clinical Trials Registry: ChiCTR1900022264.

UNASSIGNED: Totally extraperitoneal (TEP) endoscopic hernioplasty and Lichtenstein hernioplasty are the most commonly used approaches for inguinal hernia repair. However, current evidence on which is the preferred approach is inconclusive. This updated meta-analysis was conducted to track the accumulation of evidence over time.
METHODS: Studies were identified by a systematic literature search of the EMBASE, PubMed, Cochrane Library, and Google Scholar databases. Fixed- and random-effects models were used to cumulatively assess the accumulation of evidence over time.
RESULTS: The TEP cohort showed significantly higher rates of recurrences and vascular injuries compared to the Lichtenstein cohort; [Peto Odds ratio (OR) = 1.58 (1.22, 2.04), p = 0.005], [Peto OR = 2.49 (1.05, 5.88), p = 0.04], respectively. In contrast, haematoma formation rate, time to return to usual activities, and local paraesthesia were significantly lower in the TEP cohort compared to the Lichtenstein cohort; [Peto OR = 0.26 (0.16, 0.41), p ≤ 0.001], [mean difference = - 6.32 (- 8.17, - 4.48), p ≤ 0.001], [Peto OR = 0.26 (0.17, 0.40), p ≤ 0.001], respectively.
CONCLUSIONS: This study, which is based on randomised-controlled trials (RCTs) of high quality, showed significantly higher rates of recurrences and vascular injuries in the TEP cohort than in the Lichtenstein cohort. In contrast, rate of postoperative haematoma formation, local paraesthesia, and time to return to usual activities were significantly lower in the TEP cohort than in the Lichtenstein cohort. Future multicentre RCTs with strict adherence to the standards recommended in the Consolidated Standards of Reporting Trials guidelines will shed further light on the topic.

OBJECTIVE: The Open Lichtenstein technique, the Laparoscopic Trans-Abdominal PrePeritoneal (TAPP), the Totally Extra Peritoneal (TEP), and the robotic TAPP (rTAPP) are commonly performed. The aim of the present network meta-analysis was to globally compare short-term outcomes within these major surgical techniques for primary unilateral inguinal hernia repair.
METHODS: PubMed, EMBASE, and Web of Science were consulted. A fully Bayesian network meta-analysis was performed.
RESULTS: Sixteen studies (51.037 patients) were included. Overall, 35.5% underwent Open, 33.5% TAPP, 30.7% TEP, and 0.3% rTAPP. The postoperative seroma risk ratio (RR) was comparable considering TAPP vs. Open (RR 0.91; 95% CrI 0.50-1.62), TEP vs. Open (RR 0.64; 95% CrI 0.32-1.33), TEP vs. TAPP (RR 0.70; 95% CrI 0.39-1.31), and rTAPP vs. Open (RR 0.98; 95% CrI 0.37-2.51). The postoperative chronic pain RR was similar for TAPP vs. Open (RR 0.53; 95% CrI 0.27-1.20), TEP vs. Open (RR 0.86; 95% CrI 0.48-1.16), and TEP vs. TAPP (RR 1.70; 95% CrI 0.63-3.20). The recurrence RR was comparable when comparing TAPP vs. Open (RR 0.96; 95% CrI 0.57-1.51), TEP vs. Open (RR 1.0; 95% CrI 0.65-1.61), TEP vs. TAPP (RR 1.10; 95% CrI 0.63-2.10), and rTAPP vs. Open (RR 0.98; 95% CrI 0.45-2.10). No differences were found in term of postoperative hematoma, surgical site infection, urinary retention, and hospital length of stay.
CONCLUSIONS: This study suggests that Open, TAPP, TEP, and rTAPP seem comparable in the short term. The surgical management of inguinal hernia is evolving and the effect of the adoption of innovative minimally invasive techniques should be further investigated in the long term. Ultimately, the choice of the most suitable treatment should be based on individual surgeon expertise and tailored on each patient.

Compare testicular perfusion between the herniated and the healthy side pre- and post-surgery.
Our study was done on patients with unilateral inguinal hernia. A Doppler ultrasound study was performed in the healthy and herniated side before surgery and 3 months after it.
31 patients were included, 74.2% on the right and 25.8% on the left side. When comparing the pre-surgical values of testicular resistance index from the healthy side with those on the herniated side, there was a significant difference at the spermatic cord levels (0.73 ± 0.11 and 0.81 ± 0.13, p = 0.018) and the extra-testicular level (0.66 ± 0.92 and 0.74 ± 0.10, p = 0.032), but a significant difference was not present at the intra-testicular level (0.62 ± 0.07 and 0.65 ± 0.08). Three months after the surgery, there were no statistically significant differences at any of the levels studied.
There are no intra-testicular perfusion differences caused by the presence of hernia, nor during post-surgery.

BACKGROUND: The aim of this study is to evaluate sexual functions which are affected by inguinal hernias and may change after hernia repair surgery.
METHODS: A total of 47 patients who underwent Lichtenstein tension-free anterior repair and inguinal hernia surgery were evaluated in terms of erectile function, intercourse function, sexual desire, overall satisfaction and orgasm satisfaction using the International Index of Erectile function questionnaire (IIEF) scoring system before surgery and in the first and sixth months after surgery. Parameters evaluated with the IIEF score before the surgery and in the first and sixth months after surgery were compared statistically using the Wilcoxon test.
RESULTS: The average age of patients was 46.2 ±11.2 years (range: 22-67). It was determined that all scores, apart from sexual desire (p = 0.08), significantly increased in the postoperative first and sixth months compared to the preoperative period. It was measured that the preoperative sexual desire score increased significantly in the postoperative sixth month (p <0.001). A significant score was also detected when all scores in the postoperative sixth month were compared to the postoperative first month.
CONCLUSIONS: Inguinal hernia surgery positively affects sexual functions compared to the preoperative period. The improvement in sexual parameters in addition to the benefits of hernia removal and presence of no significant postoperative complications indicates that this surgery is useful and safe.
