Hernioplasty with Peritoneal Flap for the Surgical Treatment of Umbilical Hernia in Swine

BACKGROUND

Umbilical hernia is one of the most common developmental defects in swine, producing large economic losses for farmers, forced to slaughter animals at a younger age and therefore at a lower weight to prevent fatal complications. This study describes a surgical technique to repair umbilical hernia through the use of autologous prostheses, allowing recovery of the affected animals; Methods: After a general examination of the swine and examination of the lesions, the swine were anesthetized and underwent surgery. The surgery was performed by combining the traditional herniorrhaphy with the inclusion and fixation of a peritoneal flap obtained from the incision of the same hernial sac; Results: Follow-ups were carried out at 7, 30 and 60 days and demonstrated healing in all of the treated subjects; Conclusions: The use of this surgical technique allows for providing resistance to herniorrhaphy performed through the use of a cost-free autologous biomaterial prosthesis, with excellent tissue compatibility. This might allow for reducing significantly the rate of relapses and eliminating the risk of rejection.

Surgical approach and etiopathogenetic considerations to the umbilical tumefactions in cattle: Case review in twenty years (2000/2020)

Objective

Our investigation was conducted to evaluate the incidence of umbilical pathologies and the result of related surgical interventions in Sicilian cattle.

Study design

320 (214 females, 106 males) cattle with umbilical lesions were collected, anesthetized, operated on and follow-up recorded. We evaluated the injury incidence rate.

Population

The animals considered were: high productivity dairy cattle (Holstein Friesian and Brown Swiss); meat breeds (Charolaise and Limousine) and some crosses.

Results

The highest injury rate was simple omphalocele, followed by purulent omphalitis. A high percentage was found in young cattle. Friesians are the most prone to navel diseases. The dairy breeds, compared to the meat breeds, and double aptitude and crosses, were the most affected. The most common was simple omphalocele, with a small hernial port (1 to 3 cm), while the rest was greater than 3 cm, with severe organs or complications.

Methods

the most commonly used surgery was herniorraphy with autologous reinforcement, while classic sutures and mesh sutures were used in the remaining cases. Follow-up demonstrated healing in most of the treated subjects.

Conclusions

The study aimed to estimate some surgical clinical cases in Sicilian cattle. Most injuries are lower abdomen injuries, mostly simple or complicated umbilical hernias. Young dairy females were the most affected.

Meaning/Impact

Radical surgery is the treatment of choice in the vast majority of symptomatic or asymptomatic umbilical diseases; moreover, the correct management and the choice of an appropriate surgical approach allow to obtain an effective treatment of the lesions.

Simple summary

In cattle farm, the correct management of births is a fundamental step for the future of the breeding. In fact, there are numerous critical factors in this phase: calving area management, umbilical disinfection, correct administration of colostrum, management of individual pens. Generally, after a few hours from birth, the calf is transferred in individual pens, the walls of this box allow visual and tactile contact but avoid the possibility of mutual sucking of the umbilical region, a risk factor, in that area, of infections and hernias. In the study have been collected umbilical interventions carried out over twenty years by a team operating in south-eastern Sicily: Ragusa. Out of a total of 320 cases, have been reported: the prevalence of types of umbilical tumefactions, anesthetic techniques and surgical techniques performed. The purpose of the work was to highlight any predispositions of race, sex, age regarding the lesion considered and above all, the effectiveness of the surgical therapy.

Describing and Characterizing the Literature Regarding Umbilical Health in Intensively Raised Cattle: A Scoping Review

The objective of this scoping review was to describe and characterize the existing literature regarding umbilical health and identify gaps in knowledge. Six databases were searched for studies examining umbilical health in an intensively raised cattle population. There were 4249 articles initially identified; from these, 723 full text articles were then screened, with 150 articles included in the review. Studies were conducted in the USA (n = 41), Brazil (n = 24), Canada (n = 13), UK (n = 10), and 37 additional countries. Seventeen were classified as descriptive, 24 were clinical trials, and 109 were analytical observational studies. Umbilical outcomes evaluated in descriptive studies were infection (n = 11), parasitic infection (n = 5), and hernias (n = 2). Of the clinical trials, only one examined treatment of navel infections; the remainder evaluated preventative management factors for navel health outcomes (including infections (n = 17), myiasis (n = 3), measurements (n = 5), hernias (n = 1), and edema (n = 1)). Analytical observational studies examined risk factors for umbilical health (n = 60) and umbilical health as a risk factor (n = 60). Studies examining risk factors for umbilical health included navel health outcomes of infections (n = 28; 11 of which were not further defined), hernias (n = 8), scoring the navel sheath/flap size (n = 16), myiasis (n = 2), and measurements (n = 6). Studies examining umbilical health as a risk factor defined these risk factors as infection (n = 39; of which 13 were not further defined), hernias (n = 8; of which 4 were not further defined), navel dipping (n = 12), navel/sheath scores as part of conformation classification for breeding (n = 2), measurements (n = 3), and umbilical cord drying times (n = 2). This review highlights the areas in need of future umbilical health research such as clinical trials evaluating the efficacy of different treatments for umbilical infection. It also emphasizes the importance for future studies to clearly define umbilical health outcomes of interest, and consider standardization of these measures, including time at risk.

Comparison between open and closed methods of herniorrhaphy in calves affected with umbilical hernia

Umbilical hernias in calves commonly present to veterinary clinics, which are normally secondary to failure of the normal closure of the umbilical ring, and which result in the protrusion of abdominal contents into the overlying subcutis. The aim of this study was to compare the suitability of commonly-used herniorrhaphies for the treatment of reducible umbilical hernia in calves. Thirty-four clinical cases presenting to the Veterinary Teaching Hospital, Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh from July 2004 to July 2007 were subjected to comprehensive study including history, classification of hernias, size of the hernial rings, presence of adhesion with the hernial sacs, postoperative care and follow-up. They were reducible, non-painful and had no evidence of infection present on palpation. The results revealed a gender influence, with the incidence of umbilical hernia being higher in female calves than in males. Out of the 34 clinical cases, 14 were treated by open method of herniorrhaphy and 20 were treated by closed method. Complications of hernia were higher (21%) in open method-treated cases than in closed method-treated cases (5%). Hernia recurred in three calves treated with open herniorrhaphy within 2 weeks of the procedure, with swelling in situ and muscular weakness at the site of operation. Shorter operation time and excellent healing rate (80%) were found in calves treated with closed herniorrhaphy. These findings suggest that the closed herniorrhaphy is better than the commonly-used open method for the correction of reducible umbilical hernia in calves.
