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.

In the treatment of pelvic organ prolapse, the insertion of polypropylene mesh is often necessary but can lead to subsequent complications, such as a high incidence of pain and infections, necessitating mesh removal. However, the removal of polypropylene mesh can be challenging due to the risks of postoperative complications and technical difficulties. The key to effective healing often lies in the complete removal of the mesh, but this process is associated with complications, including severe pain and potential foreign body reactions. These challenges underscore the need for less invasive and more precise removal techniques. In our clinical practice, traditional approaches, such as vaginal and open abdominal surgeries, have often been hindered by limited visibility and accessibility at the mesh fixation sites. To address these issues, our team has pioneered the development of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for mesh removal. This innovative and minimally invasive technique, performed through the vaginal route, holds particular promise for repairs within the pelvic cavity. vNOTES not only enhances surgical visibility but also reduces the invasiveness of the procedure. In this case report, we present an 85-year-old female patient, who underwent transvaginal mesh (TVM) insertion at the age of 68 years. The patient developed pain in the left buttock, left lower back, and vulvar region, necessitating the removal of TVM. The vNOTES approach significantly reduced postoperative pain and complications, enabling efficient and safe removal of the polypropylene mesh. Moreover, the pathological examination of the polypropylene mesh, which was causing hip and buttock pain, revealed the presence of poor granulation tissue, indicative of a specific pathological tissue pattern. To the best of our knowledge, this is the first detailed account of the successful application of vNOTES in mesh removal.

Background: The study aimed to evaluate the clinical effects of utilizing acellular dermal matrix (ADM) for treating pelvic organ prolapse. The motivation behind exploring a new treatment method stems from the limited efficacy of current surgical options, which are often associated with side effects. Methods: Ten patients with reproductive organ prolapse underwent surgery at the Chair and Department of Gynecology, Obstetrics, and Gynecological Oncology in Katowice. ADM was used as a support material, with eight patients receiving double TOT and two undergoing a six-point fixation mesh procedure. Pelvic organ prolapse was evaluated pre-operatively and one month post-surgery using the Pelvic Organ Prolapse Quantification (POP-Q) System. General medical history and complaints were assessed using the short form (PFDIQ-SF20). The study included ten patients aged 39 to 71 (mean: 63.6 years), all with a history of at least one vaginal delivery (mean of two). None had undergone a cesarean section. Four patients exhibited POP-Q 3, and five had POP-Q 2. Results: The mean PFDIQ-SF20 score before surgery was 70.6 points. No major complications occurred during or after surgery. One patient experienced a vaginal fungal infection and an allergic reaction to sutures. Post-operation, ailments reduced by an average of 60.76 points, with five patients reporting no complaints. Conclusions: ADM emerges as a material of interest for gynecological surgery, with initial reports highlighting its effectiveness and optimistic safety profile. Further research is warranted to explore its potential as a promising option in pelvic organ prolapse treatment.

Background The use of polypropylene mesh in laparoscopic sacrocolpopexy (LSC) is a common treatment for pelvic organ prolapse (POP). Despite its widespread application, postoperative complications such as mesh pain and infection sometimes necessitate the removal of the mesh. However, it remains unclear in which cases mesh removal is warranted. Our research focused on the pathological changes at the sacral fixation point of the mesh. We sought to evaluate the pathological alterations of the sacral mesh removed through an innovative approach of transvaginal natural orifice transluminal endoscopic surgery (vNOTES). Methods This retrospective study included nine patients who underwent mesh removal surgery at the Yokosuka Urogynecology and Urology Clinic in 2023. Extraction surgery was performed using vNOTES with the GelPoint Access Platform (Applied Medical JAPAN HEADQUARTERS, Tokyo, Japan). Non-ablative Erbium YAG and Neodymium YAG lasers (RenovaLase, SP Dynamis; Fotona d.o.o., Ljubljana, Slovenia) were utilized for persistent stress urinary incontinence, fecal incontinence, vaginal erosion, and bleeding after surgery. Patients were categorized based on mesh fixation conditions, including unintended mesh overlap (Group I), excessive traction (Group II), and signs of mesh aging (Group III). This categorization helped to understand the distinct pathological outcomes associated with each condition. Results Pathological findings from the mesh removed via vNOTES varied significantly across the groups. In Group I, characteristic large vacuole formation and accumulation of atypical giant cells were observed, attributed to mesh overlap. Group II presented with vacuole formation, fiber degradation, and tissue destruction as a result of excessive mesh traction. In Group III, the aging of the mesh was marked by cracks in the surrounding tissues and granuloma formation. These detailed observations provide crucial insights into the underlying causes of mesh-related pain and other complications, highlighting the complexity of bodily responses to mesh implants. Conclusion This study demonstrated the effectiveness of vNOTES for polypropylene mesh removal in patients with post-LSC complications, resulting in significant pain reduction. Pathological analysis revealed that mesh-related issues stem from the surgical techniques, mesh properties, and long-term bodily reactions. These findings provide valuable insights for improving mesh design and POP treatment strategies. Despite the technical challenges, vNOTES is recommended for mesh removal in patients with pain. Additionally, the combination of UEL, VEL, targeted laser irradiation, AEL, and Nd:YAG laser treatments showed promising results in managing post-mesh removal complications such as stress urinary incontinence, vaginal erosion, bleeding, and fecal incontinence, offering hope for improved patient outcomes.

Background Vaginal erosion caused by the polypropylene mesh is a serious side effect, and the development of effective treatment methods is required. This study explored the potential of non-ablative vaginal erbium yttrium aluminum garnet (YAG) laser treatment (VEL) as a novel treatment approach. Methods In this study, VEL was performed on nine women who experienced vaginal erosion after undergoing treatment for pelvic organ prolapse (POP) with polypropylene mesh. These patients visited our hospital between April and December 2020. Using the Renovalase (SP Dynamis Fotona d.o.o., Ljubljana, Slovenia), the laser was applied to the entire vagina, with intensive irradiation focused on the erosion areas. Detailed analyses of symptoms before and after treatment, as well as histopathological changes, were conducted one year post-treatment. Results Nine women were referred to our hospital due to vaginal erosion caused by polypropylene mesh. The participants\' average age was 73.2 years (range: 69-81 years), with four patients having undergone transvaginal mesh (TVM) surgery and five undergoing laparoscopic sacrocolpopexy (LSC). The average time from mesh insertion to treatment initiation was 7.2 years (range: 3-15 years), with eight patients having previously attempted mesh removal. Post-treatment, significant improvements were observed in managing vaginal erosion and related bleeding, corroborated by histopathological analysis confirming cell regeneration and tissue repair. These improvements also resulted in significant improvements in bleeding management and quality of life (QoL). Conclusion VEL suggests the possibility of being an effective treatment method for vaginal erosion caused by a polypropylene mesh. However, further research is needed because of the small sample size and the limitations inherent in the retrospective case series design.

Osteosarcoma is the most common tumour that develops in the chest wall of dogs; an extensive excision is the treatment of choice. Various methods have been reported for reconstruction of chest wall defects following extensive excision. The objective of this report was to describe the complete resection of an extensive costal osteosarcoma with an extended resection of the ribs and part of the diaphragm in a dog. An 11-year-old neutered, male, miniature pinscher was presented with dyspnoea: An extensive mass was observed, stretching from the right chest wall to the abdominal wall. On computed tomography, the mass originated from the right 9th rib and exceeded the 6th rib on the cranial side and the 13th rib on the caudal side; it was compressing the lungs, diaphragm, liver, stomach and duodenum. When the patient\'s condition was medically stabilized, the tumour was removed from the right 9th rib. In consideration of the surgical margin, the 5th-13th ribs were excised, and the tumour was resected with the thoracoabdominal wall and part of the diaphragm. The missing thoracoabdominal wall and section of the diaphragm were reconstructed using two sheets of a polypropylene mesh. Postoperatively, flail chest was observed, although dyspnoea was not observed in the patient. Histopathological examination confirmed the diagnosis of osteosarcoma with a clean margin. Although 60.6 months have passed post-surgery, no metastasis has reoccurred. In this case, complete resection and reconstruction of the chest wall and diaphragm were achieved using a polypropylene mesh without fatal postoperative complications, despite extensive osteosarcoma resection.

UNASSIGNED: This study aimed to describe the technique for the surgical repair of perineal hernia (PH) in dogs using a polypropylene mesh (PM) and to evaluate its outcomes.
UNASSIGNED: All dogs were placed in the Trendelenburg position. Castration and caudal celiotomy for cystopexy and colopexy were performed as needed. Ipsilateral perianal incision was performed in the affected hernia side. A PM was formed a cone-shape with suturing and placed in hernial foramen. The PH was repaired with suturing between PH and pelvic diaphragm including the sacrotuberous ligament, internal obturator muscle, and external anal sphincter muscle. The medical records of all dogs were reviewed to evaluate signalment, perioperative findings, postoperative complications, and prognosis.
UNASSIGNED: Of the 22 dogs, 15 were intact, and 7 were previously neutered. The median age and body weight were 10 years and 6.8 kg, respectively. The PH reconstruction using a cone-shaped PM was feasible in all dogs. The median operative time was 60.5 min for unilateral PH and 109 min for bilateral PH. Major postoperative complications occurred in seven dogs (32%), and three dogs (14%) had a recurrence of PH. In the long-term (> 2 weeks) follow-up period, 16 dogs (73%) had an excellent prognosis.
UNASSIGNED: Our study suggests that PH reconstruction surgery using a cone-shaped PM may be a viable treatment method for PH in dogs. Therefore, a cone-shaped PM could serve as an alternative treatment option for canine PH reconstruction.

Incisional hernia is a frequent complication after abdominal surgery. A previous study on rats evaluated the use of a Pectin-Honey Hydrogel (PHH)-coated polypropylene (PP) mesh for the healing of acute hernias. However, there are no studies investigating the use of PHH in association with PP mesh in chronic contaminated hernia. The aims of this study are to assess the effectiveness of PHH in promoting abdominal hernia repaired with PP mesh and in counteracting infection. Twenty Sprague Dawley male rats were enrolled and a full thickness defect was made in the abdominal wall. The defect was repaired after 28 days using a PP mesh, and a culture medium (Tryptone Soy Broth, Oxoid) was spread onto the mesh to contaminate wounds in both groups. The rats were randomly assigned to a treated or untreated group. In the treated group, a PHH was applied on the mesh before skin closure. At euthanasia-14 days after surgery-macroscopical, microbiological and histopathological evaluations were performed, with a score attributed for signs of inflammation. An immunohistochemical investigation against COX-2 was also performed. Adhesions were more severe (p = 0.0014) and extended (p = 0.0021) in the untreated group. Bacteriological results were not significantly different between groups. Both groups showed moderate to severe values (score > 2) in terms of reparative and inflammatory reactions at histopathological levels. The use of PHH in association with PP mesh could reduce adhesion formation, extension and severity compared to PP mesh alone. No differences in terms of wound healing, contamination and grade of inflammation were reported between groups.

UNASSIGNED: Lumbar hernias are a rare type of hernia that occur in the posterior abdomen; they represent less than 3 % of all hernias, and approximately 350 cases have been reported in the medical literature. They can be categorized as congenital, traumatic, incisional, and spontaneous. Clinically they are not different from other hernias and the gold standard for diagnosis is computed tomography (CT) followed by tension-free plasty treatment.
METHODS: We present the case of a 15-year-old female patient with a Petit\'s hernia, who was successfully treated using tension-free plasty.
UNASSIGNED: Petit\'s hernia occurs more commonly between the ages of 50 and 70 years. Our case involved a 15-year-old female patient with a clinical presentation of an uncomplicated hernia that was managed by tension-free plasty.
CONCLUSIONS: Petit\'s hernia is an uncommon hernia that requires a high index of suspicion the support of imaging studies to confirm diagnosis and provide treatment.

Hernia reconstruction is one of the most frequently practiced surgical procedures worldwide. Plastic surgery plays a pivotal role in reestablishing desired abdominal wall structure and function without the drawbacks traditionally associated with general surgery as excessive tension, postoperative pain, poor repair outcomes, and frequent recurrence. Surgical meshes have been the preferential choice for abdominal wall hernia repair to achieve the physical integrity and equivalent components of musculofascial layers. Despite the relevant progress in recent years, there are still unsolved challenges in surgical mesh design and complication settlement. This review provides a systemic summary of the hernia surgical mesh development deeply related to abdominal wall hernia pathology and classification. Commercial meshes, the first-generation prosthetic materials, and the most commonly used repair materials in the clinic are described in detail, addressing constrain side effects and rational strategies to establish characteristics of ideal hernia repair meshes. The engineered prosthetics are defined as a transit to the biomimetic smart hernia repair scaffolds with specific advantages and disadvantages, including hydrogel scaffolds, electrospinning membranes, and three-dimensional patches. Lastly, this review critically outlines the future research direction for successful hernia repair solutions by combing state-of-the-art techniques and materials.
