Hernias are a common medical condition characterized by the protrusion of organs or tissues through weakened muscle walls, affecting millions worldwide annually. Historically, from being treated with open surgeries using tension-free mesh repairs, the landscape of hernia repair has evolved significantly. This evolution has been marked by the advent and refinement of minimally invasive techniques, including laparoscopic and robotic-assisted approaches, which offer reduced postoperative pain, shorter recovery times, and improved patient outcomes compared to traditional methods. This comprehensive review aims to elucidate the evolution of hernia repair techniques, emphasizing the transition from conventional mesh repairs to advanced minimally invasive methodologies. By examining the historical progression and current state of hernia surgery, this review thoroughly analyzes the advancements in surgical techniques, materials, and technologies. Furthermore, it explores emerging trends such as biological meshes, ultrasound-guided procedures, and 3D printing applications in hernia repair. The clinical significance of these advancements lies in their potential to enhance the patient\'s quality of life, minimize complications, and optimize healthcare resource utilization. Insights gained from this review will inform clinicians and researchers about the efficacy, safety, and comparative effectiveness of various hernia repair approaches, guiding future directions in hernia management and fostering innovation in surgical practice.

BACKGROUND: Ventral hernia is a common surgical problem among patients with end-stage kidney disease (ESKD), while the optimal repair technique for small ventral hernias is controversial. This study aimed to compare the outcomes of open suture repair versus biological mesh repair of small ventral hernias with defect size ≤2 cm in ESKD patients.
METHODS: Data from consecutive ESKD patients who underwent elective ventral hernia repair with defect size ≤2 cm at a single institution from January 2012 to January 2022 were retrospectively reviewed. Outcomes of open suture repair were compared to PermacolTM mesh repair. The primary outcome was recurrence rate. Secondary outcomes included post-operative complications, peri-operative and post-operative dialysis regimen.
RESULTS: Forty-seven ventral hernia repairs were included, with 20 being suture repairs and 27 being PermacolTM mesh repairs. Median age at hernia repair was 60 (range 32-81) years old. Pre-operatively, 42 patients (89.4%) were on peritoneal dialysis (PD). Paraumbilical hernia (59.6%) was most common. Median hernia defect size was 15 mm (range 2-20 mm). Upon median follow-up of 56 (range 9-119) months, more patients in the suture repair group developed recurrence (30% vs. 0%, p = 0.004). Median time to recurrence was 10 (range 5-16) months. There was no wound or mesh infection. The majority of patients underwent intermittent PD peri-operatively and were able to resume on PD in the long run.
CONCLUSIONS: Ventral hernia repair is indicated in ESKD patients even for small defects; repair with PermacolTM mesh was associated with a lower recurrence rate when compared to suture repair and post-operative morbidity was low.

Desmoid tumors, while generally benign histologically, can exhibit locally aggressive behavior, especially when located in the anterior abdominal wall. This case report explores the management of a rare giant desmoid tumor complicated by concurrent lymphedema, emphasizing the nuances of diagnosis, treatment decisions, and their impact on the patient\'s quality of life. The patient, a 55-year-old obese individual with a BMI of 47, presented with a 25 cm mass in the right paraumbilical region, alongside significant lymphedema in the right lower limb and associated inguinal lymphadenopathy. Abdominal CT revealed a well-defined soft tissue mass in the right paramedian hypogastric region, suggestive of a desmoid tumor. Surgical intervention involved a monobloc resection of the mass with a 5 cm lateral margin, including the right rectus abdominis muscle and associated aponeuroses, and subsequent reconstruction using a biface intraperitoneal synthetic mesh. Postoperative recovery was marked by the resolution of lymphedema and a return to full function of the affected limb. Histopathological examination confirmed the diagnosis of a desmoid tumor. This case underscores the importance of radical surgical resection with adequate margins and appropriate reconstruction to achieve favorable long-term outcomes. The report provides insights for future research and therapeutic advancements in the management of desmoid tumors.

An arcuate line hernia is a generally asymptomatic, ascending protrusion of intraperitoneal structures over the linea arcuata. Arcuate line herniae are scarcely reported in the literature. Only a few publications were found. No clear descriptions of the techniques for repair have been published either. We aim to provide diagnostic images and illustrate our method to repair this hernia.

BACKGROUND: Hiatal hernia (HH) repairs have been associated with high recurrence rates. This study aimed to investigate if changes in patient\'s self-reported GERD health-related quality of life (HRQL) scores over time are associated with long-term surgical outcomes.
METHODS: Retrospective chart reviews were conducted on all patients who had laparoscopic or robotic HH repairs between 2018 and 2022 at a tertiary care center. Information was collected regarding initial BMI, endoscopic HH measurement, surgery, and pre- and post-operative HRQL scores. Repeat imaging at least a year following surgical repair was then evaluated for any evidence of recurrence. Paired t tests were used to compare pre- and post-operative HRQL scores. Wilcoxon ranked-sum tests were used to compare the HRQL scores between the recurrence cohort and non-recurrence cohorts at different time points.
RESULTS: A total of 126 patients underwent HH repairs and had pre- and post-operative HRQL scores. Mesh was used in 23 repairs (18.25%). 42 patients had recorded HH recurrences (33.3%), 35 had no evidence of recurrence (27.7%), and 49 patients (38.9%) had no follow-up imaging. The average pre-operative QOL score was 24.99 (SD ± 14.95) and significantly improved to 5.63 (SD ± 8.51) at 2-week post-op (p < 0.0001). That improvement was sustained at 1-year post-op (mean 7.86, SD ± 8.26, p < 0.0001). The average time between the initial operation and recurrence was 2.1 years (SD ± 1.10). Recurrence was significantly less likely with mesh repairs (p = 0.005). There was no significant difference in QOL scores at 2 weeks, 3 months, 6 months, or 1 year postoperatively between the cohorts (p = NS).
CONCLUSIONS: Patients had significant long-term improvement in their HRQL scores after surgical HH repair despite recurrences. The need to re-intervene in patients with HH recurrence should be based on their QOL scores and not necessarily based on established recurrence.

OBJECTIVE: As Japanese society ages, the number of surgeries performed in elderly patients with hiatal hernia (HH) is increasing. In this study, we examined the feasibility, safety, and potential effectiveness of the addition of anterior gastropexy to hiatoplasty with or without mesh repair and/or fundoplication in elderly Japanese HH patients.
METHODS: We retrospectively evaluated 39 patients who underwent laparoscopic HH repair between 2010 and 2021. We divided them into 2 groups according to age: the \"younger\" group (< 75 years old, n = 21), and the \"older\" group (≥ 75 years old, n = 18). The patient characteristics, intraoperative data, and postoperative results were collected.
RESULTS: The median ages were 68 and 82 years old in the younger and older groups, respectively, and the female ratio was similar between the groups (younger vs. older: 67% vs. 78%, p = 0.44). The older group had more type III/IV HH cases than the younger group (19% vs. 83%, p < 0.001). The operation time was longer in the older group than in the younger group, but there was no significant difference in blood loss, perioperative complications, or postoperative length of stay between the groups. The older group had significantly more cases of anterior gastropexy (0% vs. 78%, p < 0.001) and less fundoplication (100% vs. 67%, p = 0.004) than the younger group. There was no significant difference in HH recurrence between the groups (5% vs. 11%, p = 0.46).
CONCLUSIONS: The addition of anterior gastropexy to other procedures is feasible, safe, and potentially effective in elderly Japanese patients with HH.

OBJECTIVE: Incisional hernia (IH) is a common complication following abdominal surgery. Surgical repair of IH is associated with the alleviation of symptoms and improvement of quality of life. Operative intervention can pose a significant burden to the patient and healthcare facilities. This study aims to describe and compare outcomes of elective and emergency surgical repair of IH.
METHODS: This study is a single-centre comparative retrospective study including patients who had repair of IH. Patients were divided into Group I (Emergency) and Group II (Elective), and a comparison was conducted between them.
RESULTS: Two hundred sixty-two patients were identified with a mean age of 61.8 ± 14.2 years, of which 152 (58%) were females. The mean BMI was 31.6 ± 7.2 kg/m2. More than 58% had at least one comorbidity. 169 (64.5%) patients had an elective repair, and 93 (35.5%) had an emergency repair. Patients undergoing emergency repair were significantly older and had higher BMI, p = 0.031 and p = 0.002, respectively. The significant complication rate (Clavien-Dindo III and IV) was 9.54%. 30 and 90-day mortality rates were 2.3% (n = 6) and 2.68% (n = 7), respectively. In the emergency group, the overall complications, 30-day and 90-day mortality rates were significantly higher than in the elective group, p ≤ 0.001, 0.002 and 0.001, respectively. Overall, 42 (16.1%) developed wound complications, 25 (9.6%) experienced a recurrence, and 41 (15.71%) were readmitted within 90 days, without significant differences between the two groups.
CONCLUSIONS: Patients who underwent emergency repair were significantly older and had a higher BMI than the elective cases. Emergency IH repair is associated with higher complication rates and mortality than elective repair.

Aim: Women have the highest prevalence of epigastric hernia repair. Outcomes after epigastric hernia repair are rarely reported independently, although pathology and surgical techniques may be different than for other primary ventral hernias. The aim of this study was to evaluate long-term outcomes after epigastric hernia repairs in women on a nationwide basis. Methods: Nationwide cohort study from the Danish Hernia Database. Complete data from women undergoing elective epigastric hernia repair during a 12 years period (2007-2018) was extracted. A 100% follow-up was obtained by combining data from the National Civil Register. The primary outcome was operation for recurrence, secondary outcomes were readmission and operation for complications. Outcomes for open sutured repair, open mesh repair mesh, and laparoscopic repairs were compared. Results: In total, 3,031 women underwent elective epigastric hernia repair during the study period. Some 1,671 (55.1%) women underwent open sutured repair, 796 (26.3%) underwent open mesh repair, and 564 (18.6%) underwent laparoscopic repair. Follow-up was median 4.8 years. Operation for recurrence was higher after sutured repairs than after open mesh and laparoscopic repairs (7.7% vs. 3.3%, vs. 6.2%, p < 0.001). The risk of operation for complications was slightly higher after open mesh repair compared with sutured repair and laparoscopic repair (2.6% vs. 1.2%, vs. 2.0%, p = 0.032), with more operations for wound complications in the open mesh group (2.0%, p = 0.006). Conclusion: More than half of the women underwent a suture-based repair, although mesh repair reduces risk of recurrence. Open mesh repair had the lowest risk of recurrence, but on the expense of slightly increased risk of wound-related complications.

Abdominal wall reconstruction (AWR) is a surgical procedure performed to address various conditions such as hernias, incisional hernias, and complex abdominal wall defects. Mesh fixation plays a crucial role in providing mechanical reinforcement to the weakened abdominal wall during AWR. Traditionally, suturing has been the preferred method for mesh fixation; however, adhesion techniques using tissue adhesives or glues have gained attention as an alternative approach. This systematic review aims to compare suturing and adhesion techniques for mesh fixation in AWR and assess their effectiveness in preventing hernia recurrence. A comprehensive literature search was conducted across relevant databases, including PubMed, MEDLINE, Embase, and the Cochrane Library. Studies that fulfilled the predetermined eligibility criteria were included. The primary outcome measure of interest was hernia recurrence rates. Secondary outcomes included mesh-related complications, surgical site infections, patient-reported outcomes, and functional outcomes. A risk of bias assessment was performed for the included studies, and data were synthesized qualitatively. Overall, the results of the included studies suggest that atraumatic mesh fixation with glue may have the potential to reduce chronic groin pain (CGP). However, there were significant variations in patient selection criteria, glue administration techniques, and hernia repair methods among the trials, which limited the ability to draw definitive conclusions. Additionally, the definitions of CGP and measurement scales for postoperative pain varied across studies, making it challenging to compare outcomes. The limitations of the review include the small sample sizes in some trials, relatively short follow-up durations, and the lack of standardized criteria for assessing variables such as foreign body sensation and groin compliance. Furthermore, the economic implications of using glue fixation compared to traditional suture fixation need to be considered.

Incisional hernia (IH) is a frequent complication following abdominal surgery. The development of IH could be more sophisticated than a simple anatomical failure of the abdominal wall. Reported IH incidence varies among studies. This review presented an overview of definitions, molecular basis, risk factors, incidence, clinical presentation, surgical techniques, postoperative care, cost, risk prediction tools, and proposed preventative measures. A literature search of PubMed was conducted to include high-quality studies on IH. The incidence of IH depends on the primary surgical pathology, incision site and extent, associated medical comorbidities, and risk factors. The review highlighted inherent and modifiable risk factors. The disorganisation of the extracellular matrix, defective fibroblast functions, and ratio variations of different collagen types are implicated in molecular mechanisms. Elective repair of IH alleviates symptoms, prevents complications, and improves the quality of life (QOL). Recent studies introduced risk prediction tools to implement preventative measures, including suture line reinforcement or prophylactic mesh application in high-risk groups. Elective repair improves QOL and prevents sinister outcomes associated with emergency IH repair. The watchful wait strategy should be reviewed, and options should be discussed thoroughly during patients\' counselling. Risk stratification tools for predicting IH would help adopt prophylactic measures.
