The objective was to explore the efficacy of single-port laparoscopic percutaneous extraperitoneal closure using double-modified hernia needles with hydrodissection (SLPEC group) and two-port laparoscopic percutaneous extraperitoneal closure (TLPEC group) for the treatment of giant indirect inguinal hernias in children. We performed a retrospective review of all children with giant indirect inguinal hernias (inner ring orifice diameter ≥ 1.5 cm) who underwent laparoscopic high ligation of the hernia sac at FuJian Children\'s Hospital from January 2019 to December 2021. We collected data from the medical records of all the children and analysed their clinical characteristics and operation-related and follow-up information. Overall, this study included a cohort of 219 patients with isolated giant inguinal hernias who had complete clinical data and who had undergone laparoscopic high ligation of the hernia sac at our centre. All procedures were successfully performed for the 106 patients who underwent SLPEC and for the 113 patients who underwent TLPEC at our centre. There were no statistically significant differences in patient age, sex, body weight, follow-up time or the side of inguinal hernia between the SLPEC group and the TLPEC group (P = 0.123, 0.613, 0.121, 0.076 and 0.081, respectively). However, there were significant differences in the bleeding volume, visual analogue scale (VAS) score, and postoperative activity time between the two groups (P ≤ 0.001). The operation times in the TLPEC group were significantly longer than those in the SLPEC group (P = 0.048), but there were no significant differences in hospital length of stay or hospitalization costs between the two groups (P = 0.244 and 0.073, respectively). Incision scars were found in 2 patients in the SLPEC group and 9 patients in the TLPEC group, and there was a significant difference between the two groups (P = 0.04). However, the incidence of ipsilateral hernia recurrence, surgical site infection, suture-knot reactions and chronic inguinodynia did not significantly differ between the two groups (P = 0.332, 0.301, 0.332 and 0.599, respectively). Postoperative hydrocele occurred in only 1 male child in the SLPEC group and in no male children in the TLPEC group, and there was no difference between the two groups (P = 0.310). In this study, there were no cases of testicular atrophy or iatrogenic ascent of the testis. Compared with the TLPEC group, the SLPEC group had the advantages of a concealed incision, light scarring, minimal invasiveness, a reduced operation time, minimal bleeding, mild pain and rapid recovery. In conclusion, SLPEC using double-modified hernia needles with hydrodissection and high ligation of the hernia sac is a safe, effective and minimally invasive surgery. The cosmetic results are impressive, and the follow-up results are promising.

OBJECTIVE: The incidence of recurrent hernia after radical resection of prostate cancer is high, so this article discusses the incidence and risk factors of inguinal hernia after radical resection of prostate cancer.
METHODS: This case control study was conducted in The First People\'s Hospital of Huzhou clinical data of 251 cases underwent radical resection of prostate cancer in this hospital from March 2019 to May 2021 were retrospectively analyzed. According to the occurrence of inguinal hernia, the subjects were divided into study group and control group, and the clinical data of each group were statistically analyzed, Multivariate Logistic analysis was performed to find independent influencing factors for predicting the occurrence of inguinal hernia. The Kaplan-Meier survival curve was drawn according to the occurrence and time of inguinal hernia.
RESULTS: The overall incidence of inguinal hernia after prostate cancer surgery was 14.7% (37/251), and the mean time was 8.58 ± 4.12 months. The average time of inguinal hernia in patients who received lymph node dissection was 7.61 ± 4.05 (month), and that in patients who did not receive lymph node dissection was 9.16 ± 4.15 (month), and there was no significant difference between them (P > 0.05). There were no statistically significant differences in the incidence of inguinal hernia with age, BMI, hypertension, diabetes, PSA, previous abdominal operations and operative approach (P > 0.05), but there were statistically significant differences with surgical method and pelvic lymph node dissection (P < 0.05). The incidence of pelvic lymph node dissection in the inguinal hernia group was 24.3% (14/57), which was significantly higher than that in the control group 11.8% (23/194). Logistic regression analysis showed that pelvic lymph node dissection was a risk factor for inguinal hernia after prostate cancer surgery (OR = 0.413, 95%Cl: 0.196-0.869, P = 0.02). Kaplan-Meier survival curve showed that the rate of inguinal hernia in the group receiving pelvic lymph node dissection was significantly higher than that in the control group (P < 0.05).
CONCLUSIONS: Pelvic lymph node dissection is a risk factor for inguinal hernia after radical resection of prostate cancer.

Inguinal hernia repair is one of the most common surgical procedures in the pediatric population. While a rare complication, bladder injury can impose a significant burden on patients. This study outlined a case of bladder injury following selective inguinal hernia repair and summarized methods to prevent this complication, aiming to emphasize the importance of not underestimating interventions labeled as \"routine surgery\" in order to avoid avoidable harm to patients.

OBJECTIVE: To explore the efficacy and safety of single-incision laparoscopic (SIL) technique compared with the traditional three-port total extraperitoneal (TEP) technique for inguinal hernia repair.
METHODS: This prospective, randomised study involved patients who underwent surgery for inguinal hernia at our hospital from December 2021 to July 2023. Patients were randomly assigned to SIL-TEP or TEP groups based on a computer-generated random number table. Perioperative clinical indicators for the surgical approaches were evaluated.
RESULTS: Of the 127 patients eligible for study, 66 were randomised to the SIL-TEP group and 61 to the TEP group. The operation time for SIL-TEP was significantly longer than for TEP but the time to return to normal activities was significantly shorter and short-term pain score was significantly lower. There were no differences between groups in intraoperative blood loss, postoperative hospital stays, pain relief time, hospitalization costs or cosmetic satisfaction scores.
CONCLUSIONS: While SIL-TEP is more challenging than TEP for hernia repair, we found that at our centre it is comparable with regard to overall safety and feasibility. Further studies are needed to validate our findings.

Repair and reconstruction of the myopectineal orifice area using meshes is the mainstay of surgical treatment of inguinal hernias. However, the limitations of existing meshes are becoming increasingly evident in clinical applications; thus, the idea of using three-dimensionally (3D)-printed biological meshes was put forward. According to the current level of the 3D printing technology and the inherent characteristics of biological materials, the direct use of the 3D printing technology for making biological materials into finished products suitable for clinical applications is not yet supported, but synthetic materials can be first printed into 3D form carriers, compounded with biological materials, and finally made into finished products. The purpose of this study was to develop a technical protocol for making 3D-printed biomesh carriers using polyurethane as a raw material. In our study: raw material, polyurethane; weight, 20-30 g/m2; weaving method, hexagonal mesh; elastic tension aspect ratio, 2:1; diameters of pores, 0.1-1 mm; surface area, 8 × 12 cm2; the optimal printing layer height, temperature and velocity were 0.1 mm, 210-220 °C and 60 mm/s. Its clinical significance lies in: (1) applied to preoperative planning and design a detailed surgical plan; (2) applied to special types of surgery including patients in puberty, recurrent and compound inguinal hernias; (3) significantly improve the efficiency of doctor-patient communication; (4) it can shorten the operation and recovery period by about 1/3 and can save about 1/4 of the cost for patients; (5) the learning curve is significantly shortened, which is conducive to the cultivation of reserve talents.

Inguinal hernia is a prevalent surgical condition in pediatric patients. Despite the efficacy of current treatment modalities, a certain recurrence rate still persists. Hence, our objective in this study is to introduce an innovative surgical technique designed to minimize surgical complications. We conducted a retrospective analysis on 809 pediatric cases that underwent laparoscopic repair with our innovative technique for inguinal hernia from June 2020 to June 2022. Demographic information, perioperative details, and postoperative follow-up outcomes were thoroughly assessed. All surgeries were conducted laparoscopically under general anesthesia. The procedure commenced by encircling the hernia sac with two sutures under laparoscopic guidance. Subsequently, the sac was exteriorized from the body using the two sutures, followed by ligation and excision of the hernia sac. The research findings demonstrate that the duration of unilateral and bilateral procedures was recorded as 15.9 ± 4.8 and 21.7 ± 3.9 min, respectively. Incision infection occurred in 7 patients (0.87%), and Male Complicated Inguinal Hernia (MCIH) was observed in 2 patients (0.23%). Notably, there were no occurrences of iatrogenic cryptorchidism, testicular atrophy, or recurrence (0%) during the follow-up period. In conclusion, our novel modification shows a notable reduction in postoperative recurrence rates and alleviates the impact of the procedure on the positioning of the testis or uterus. This modified technique is both safe and valuable, thus warranting broader adoption and promotion.

The objective of this study was to compare the safety and efficacy of laparoscopic-assisted surgery and traditional open surgery for pediatric incarcerated inguinal hernia. A total of 58 pediatric patients with indirect incarcerated inguinal hernia between January 2014 and January 2020 were included in this study. The patients were divided into 2 groups; observational group who underwent laparoscopic-assisted surgery (n = 36), and a control group who underwent traditional open surgery (n = 22). The overall operation time, intraoperative blood loss, postoperative recovery time, length of hospital stay, occurrence of postoperative scrotal or vulvar hematomas, incidence of postoperative surgical site infection, and hernia recurrence were analyzed and compared between the 2 groups. Compared with the control group, the operation time (38.28 ± 5.90) minutes, intraoperative blood loss (1.15 ± 0.54 mL), postoperative recovery time (8.39 ± 1.42 h), and length of hospital stay (1.64 ± 0.59) were significantly lower in the observational group (P < .05). There was no incidence of scrotal or vulvar hematoma or surgical site infection in the observation group, which was significantly lower than that in the control group (P < .05). However, no statistically significant difference was found in the rate of postoperative hernia recurrence between the 2 groups (P > .05). In conclusion, laparoscopic-assisted surgery appears to be a safe and effective alternative approach to traditional open surgery for the treatment of pediatric incarcerated inguinal hernia. Its advantages include reduced trauma, faster recovery, shorter hospital stays, and fewer complications.

OBJECTIVE: To investigate the effiicacy of laparoscopic assisted microsurgical vasovasostomy in the treatment of vas deferens obstruction caused by inguinal herniorrhaphy.
METHODS: Clinical data of patients undergoing surgical treatment for deferential obstruction after inguinal hernia repair in the andrology department of the First Affiliated Hospital of Zhengzhou University from 2018 to 2022 were retrospectively analyzed, and they were divided into two groups according to different surgical methods: double mirror combined group and microscope group. The basic clinical data, intraoperative conditions, postoperative effects and complications of the two groups were compared.
RESULTS: There were 14 cases in the double mirror group and 34 cases in the microscope group. There was no significant difference in age and history of groin operation between the two groups (P>0.05). The average length of hospital stay in the two-lens group was less than that in the microscope group (5.07±0.26 days vs 7.09±1.86 days, P< 0.01), and the average operation time in the two-lens group was more than that in the microscope group (211.93±58.55min vs 162.26±40.70min, P<0.01). The postoperative recurrence rate (85.7% vs 73.5%, P > 0.05) was similar between the two groups. There was no significant difference in early postoperative complications (0% vs 2.9%, P > 0.05). Only 1 patient in the microscope group experienced fat liquefaction and recovered after intensive dressing change.
CONCLUSIONS: Laparoscope-assisted microscopy provides natural fertility opportunities for patients with vas deferens obstruction after inguinal hernia repair, reduces the difficulty of surgery and the length of hospital stay, and is a safe and effective surgical method comparable to traditional surgical methods.
