Rate Of Success

The protuberance of pelvic viscera is due to the weakness or failure of pelvic diaphragm muscles called a perineal hernia. The etiology of this disease involved in this process was poorly determined but associated with multi-factors which included gonadal hormone imbalance, rectal abnormalities, prostatic disease, and myopathy. Additionally, the prevalence of middle age and old dogs overwhelmed the young ones due to the change in livelihood and diet. Although there was a certain rate of success in treatment for perineal hernia, this disease had high proportions of recurrence and postoperative complications. This study was conducted at Sasaki Animal Hospital in Ho Chi Minh City to manage this disease by the synthetic mesh implant. A 10-year castrated male Pomeranian (5.2 kg) was referred to clinical examination because of a 4-month complaint of the return of a mass at the perineal area. The owner also reported constipation and hematuria with the presence of pus. Rectal palpation and radiography indicated that the bladder contained in the hernia sac. Ultrasound showed that the bladder contained a large clump of pus. Blood test and antimicrobial-resistant test were also performed by taking the blood and urine with a pus sample, respectively. The ill animals were treated for bacterial infection and then operated to relocate hernia by polypropylene mesh. After 14-day operation, the results were considered satisfactory, which the perineal area returned to normal without any complications. However, the recurrence of this non-infectious disease was reported to range from 10-46%. Therefore, the following health check was necessary to perform twice within a year.

This study reports a rare unilateral perineal hernia in three mature female Jaffarabadi buffaloes. The buffaloes presented with a unilateral swelling lateral to the vulvar lip. Upon palpation, the swelling was painless, soft and reducible. Ultrasonography revealed a hyperechoic hernia sac containing the urinary bladder and or motile intestine, with homogenous hypoechoic contents. The perineal hernia was repaired using polypropylene mesh after the repositioning of the retroflexed urinary bladder and/or large intestine. The clinical outcome, including postoperative complications and hernia recurrence, was found via periodic examination and telephone calls. No complications were observed for 6 months of follow-up and all the buffaloes had excellent outcomes.

Background: Perineal hernia is characterized by the displacement of abdominal organs to the perineal region after rupture or weakening of the pelvic diaphragm muscles. This condition is common among middle-aged and elderly unneutered male dogs. Considering the severity of the condition and its rarity among bitches, this paper reports on a case of perineal hernia caused by hydrometra in a 12-year-old pinscher bitch.Case: The patient was a 12-year-old Pinscher bitch, weighing 3 kg, suffering from anuria and constipation in the 36 h prior to treatment, without reported trauma. She was unspayed, and her last estrus had occurred approximately thirty days previously. The physical examination revealed an increase in volume in the right perineal region, increased volume in the left inguinal region, increased body temperature (39.8ºC), pale mucous membranes, tachycardia, tachypnea, abdominal pain and increased popliteal lymph nodes. The diagnosis was determined based on her medical history, clinical signs and an ultrasound scan, which revealed dilated uterine horns displaced unilaterally in the left inguinal region, with evidence of hydrometra, full urinary bladder inside the hernia sac in the right dorsolateral perineal region and right kidney pyelectasis. After evaluating the animal’s physical condition, surgery was recommended, involving ovariohysterectomy associated with inguinal and perineal herniorrhaphy.Discussion: Perineal hernia, a common condition in male dogs, is characterized by the displacement of organs towards the perineal region. However, in this case, this condition occurred in female dog. Unlike males, the main causes of perineal hernia in females are trauma, chronic coughing related to heart disease, bronchitis, and tracheal collapse. Increased intra-abdominal pressure associated with a weak pelvic diaphragm predisposes for herniation of abdominal contents, such as occurred through hydrometra. In this case, other factors that could pertain to the etiology of perineal hernia were excluded, given the absence of trauma or secondary diseases. The diagnosis was made based on a physical examination and ultrasound scan. Pre-surgical biochemical blood tests were also performed. The chosen treatment was ovariohysterectomy followed by inguinal and perineal herniorrhaphy. The traditional surgical procedure to reduce the perineal hernia was employed, using approximation sutures due to the easy apposition of wound edges. The structures and soft tissues involved showed no changes in color or texture, thus obviating the need for more elaborate techniques, which are employed in the case of relapse or muscle atrophy. The patient showed clinical evolution after surgical correction, with decreased perineal volume and recovery of urinary function (normuria). The patient was discharged after 72 h, and six months after the surgical procedure, she presented no clinical alteration, according to information provided in a telephone call by her owner. It is believed that the increase in volume caused by the presence of hydrometra was the determining factor for the development of inguinal and perineal hernias. It is suggested that alterations causing uterine enlargement be investigated in order to include perineal hernia in female dogs as a differential diagnostic tool.

In 16 male dogs who suffered from perineal hernia, polypropylene mesh was used to close a defect in the pelvic diaphragm. Pelvic bone was drilled on the pelvic floor and mesh was sutured through holes by polypropylene suture. Strong pelvic diaphragm, good long-term results and time-sparing by this technique was achieved. Suture sinuses were developed in two dogs one month postoperatively. Objectives of this study were to describe a new alternative technique of perineal herniorraphy and postoperative possible complications. Weakness of internal obturator muscle flap is complication which can be observed during transposition of internal obturator muscle flap. This technique can be used when internal obturator muscle flap is weak like the operation of the first choice.

Perineal hernia is the protrusion into the perineum of intraperitoneal or extraperitoneal contents through a congenital or acquired defect of the pelvic diaphragm. The first case was reported by de Garangeot in 1743. Perineal hernias may occur anteriorly or posteriorly to the superficial transverse perineal muscles. Congenital perineal hernia is a rare entity. Failure of regression of the peritoneal cul de sac of the embryo is considered a predisposing factor for hernia formation. Acquired perineal hernias are primary or secondary. Primarily acquired perineal hernias are caused by factors associated with increased intra-abdominal pressure. They are more common in females as a result of the broader female pelvis and the attenuation of the pelvic floor during pregnancy and childbirth. Secondarily acquired perineal hernias are incisional hernias associated with extensive pelvic operations such as abdominoperineal resection of the anorectum and pelvic exenteration. Pain in the perineal area, intestinal obstruction, topical skin erosion, and difficulty with urination necessitate the surgical repair of a perineal hernia. This can be accomplished through transabdominal, perineal, or combined abdominoperineal approaches. The defect in the muscles of the pelvic diaphragm may be closed either with direct suturing or by using autogenous tissues or synthetic mesh.

Background: Perineal hernia may be unilateral or bilateral and results from weakening and separation of the pelvic diaphragm muscles, favoring the abdominal viscera herniation into the perineal subcutaneous. The factors described as possible etiology of this affection are prostate hyperplasia, senile muscular atrophy, myopathy and hormonal imbalances. Several herniorrhaphy techniques are available in literature presenting different rates of success leaving the question whether there is any technique that is predominantly better than others are. This case report aims to describe five cases of perineal hernia treated with four different techniques performed by four experienced surgeons.Cases: Case 1. Semitendinous muscle transposition: A 8-year-old intact male Shitzu (6 kg) was referred for the evaluation of a swelling in the right perineal region. The mass was soft and regressed into de pelvic cavity during palpation. Abdominal ultrasound and radiography were taken, which reveled perineal hernia and a mild prostate enlargement. The patient was prepared for hernia repair with semitendinous muscle transposition and orchiectomy. Case 2. Internal obturator muscle transposition: A 9-year-old intact male mixed breed dog (18kg) presenting a two-week long unilateral (right-side) perineral hernia. Ultrasound exam revealed a cystic prostate and adipose tissue as the hernia content. After clinical and image examination the patient was submitted to surgical repair using the internal obturator muscle transposition technique and orchiectomy. Case 3. Internal obturator muscle transposition associated to correction of rectal sacculation: A 12-year-old intact male mixed breed presenting swelling on the right side of the perianal region. The owner reported a 4-day long aquesia, emesis and increased volume in perineum for 6 months. During the rectal palpation, resected fecal content was present and rectal sacculation was suspected. Enema, simple abdominal radiography, contrast radiography and ultrasonography were performed. The exams showed perineal hernia with bowel content and presence of rectal sacculation. The patient was submitted to surgery in order to correct the perineal hernia and rectal sacculation, and to performe orchiectomy. Case 4. Polypropylene mesh: A 13-year-old intact male dachshund dog (8.6 kg) was referred to clinical examination due to a 1-year-history complaint of a mass in the right perineal area. The owner also reported rectal prolapse and stranguria noted two days prior the consultation. Ultrasound and radiography showed bladder, prostate and bowel contained in hernia sac. The patient underwent to hernia repair with polypropylene mesh and castration. Case 5. Bovine pericardium preserved in 4% formaldehyde: A 7-year-old intact male mixed breed dog (14 kg) was presented to clinical evaluation with swelling lateral to the anus and dyschezia. Abdominal radiography and ultrasound revealed images suggestive of perineal hernia with urinary bladder, prostate and bowl content. The patient was referred to surgery.Discussion: Perineal herniations are commonly related to weakness of pelvic diaphragm muscles. However, the etiology involved in this process is undetermined. Success rate of perineal hernia repair techniques vary in literature. It can be speculated that local factors may influence these results, such as the surgeon ability to perform the technique or to recognize components that adversely affects the surgery. The results were considered satisfactory in all cases, which may answer the question: the better technique is the one we perform better.

The aim of the research is to determine morphological changes in the area of implantation of the polypropylene mesh implant and to determine the effect on the integration of the prosthesis of locally introduced adipose tissue and platelet rich plasma. Materials and methods. The experiment was performed on 36 sexually mature males of the Wistar line rats. The experiment simulated, studied and quantified local morphological responses and changes in developing in biological tissues that are in contact with implanted highly porous lightweight (80 g/m2) mesh implant in isolation and also in conditions of local administration of fatty graft and platelet rich plasma. Results: Assuming introduction of adipose tissue and platelet rich plasma in the zone of integration of mesh alloprosthesis under the influence of introduced regenerative cytokines as well as stromal stem cells activated by them there is an earlier activation of regenerative processes, enhanced angiogenesis which determines the optimal nature of the integration of the prosthesis with the formation of thin collagen fibers in more early terms minimizing excess peri-prosthetic fibrosis. Isolated introduction into the implantation zone of fatty suspension determines similar changes that have a slightly less pronounced character. These changes are quantitatively studied and the results obtained are statistically significant. Conclusions: Applying a fatty graft together with platelet rich plasma in the area of implantation of the lung polypropylene prosthesis, there was an accelerated tissue reaction from the integration of the prosthesis. Mesenchymal stem cells of adipose tissue that is a target for plasma cytokines enriched with thrombocytes have a more pronounced effect in stimulating reparative processes provided that they are simultaneously administered with PRP compared with isolated administration without PRP. The use of platelet rich plasma and adipose tissue design has a significant positive effect on local angiogenesis. Under conditions of improved angiogenesis and other stimulating factors in the conditions of introduction of adipose tissue and PRP, the integration of the prosthesis occurs with significantly lower peri-prosthetic fibrosis.

Relevance. Thoracoplasty is an effective way to close the cavity of destruction of the lung tissue and achieve clinical recovery in case of fibro-cavernous pulmonary tuberculosis. A promising direction of creating selective collapse in thoracoplasty is the use of synthetic mesh implants. The purpose of the study was to assess the effect of synthetic implants from the “Surgipro" polypropylene mesh on the inflammatory and reparative reaction in thoracoplasty. Materials and methods. The work was performed on male Wistar rats weighing 250±50 grams (n=12). The “Surgipro” polypropylene mesh was implanted on the right posterolateral surface of the chest (n=9). As control, the material was taken from intact rats (n=3), which were kept in the same conditions as experimental animals. The study material was biopsy specimens of the muscular aponeurotic scar of the posterolateral surface of the chest of rats. The cellular composition and total number of mast cells were determined. A clinical study was conducted on 26 cases of thoracoplastic with the use of polypropylene mesh in the pulmonary-surgical department of the Seaside regional antituberculous dispensary in Vladivostok. Results. During the experimental study, it was recorded that the implant used in the reconstruction of the chest has a pronounced reactogenicity from the first day, which manifests itself as a local inflammatory reaction with the concentration of mast cells. The population of mast cells progressively declined by the 30th day, while an increase in the number of macrophages and fibroblasts was observed with the advent of giant multinuclear cells of foreign bodies. On the 30th day after the operation, a widespread post-inflammatory reactive fibrosis and angiomatosis with chronic productive inflammation was observed in the experiment. In clinical observation, the resulting inflammatory reaction around the endoprosthesis spreads to the surrounding tissues and lung, which contributes to the formation of pronounced pulmonary fibrosis and restriction of a specific process.
