Although the observed results seem promising in preclinical models, their employment as antiadhesive agents has not been evaluated clinically, and they pose an increase in the risk of undesired side effects [ ]. Further strategies are based on the use of agents that limit cellular proliferation by preventing DNA replication, thus preventing fibroblasts from expanding and forming adhesions. Agents that present these characteristics include mitomycin-C, which has been demonstrated to reduce adhesions in a rabbit pericardial model [ ], or 5-fluoroacil, which also reduced adhesions in the flexor tendon in chickens [ ].
However, the side effects of these drugs still represent a crucial limitation for their use as antiadhesive agents. Oestrogen is a hormone produced in the ovaries that plays a crucial role in endometrium development; thus, it could have a potential effect on the prevention of intrauterine adhesion formation. However, the use of oestrogen after hysteroscopy has not been demonstrated to provide significant positive effects [ 55 ].
Alternatively, oestrogen seems to be effective for the treatment of women with intrauterine adhesions, although combination with other systems that provide sustained release could improve patient outcomes [ ]. Other methods, including anticoagulants heparin , antioxidants vitamin C or neutralising antibodies for fibrinolytic inhibitors and inflammatory cytokines [ ], have also been investigated.
Although some of these agents showed positive results in animal studies, no conclusive data supporting their efficacy have been reported.
Notwithstanding, the use of combined therapies that merge mechanical barriers and antiadhesive agents may support a promising approach to prevent the formation of adhesions in different surgeries. Other investigations have shown only limited results or modest improvements in animal studies [ 78 ].
Recent advances in molecular biology have also enabled new strategies adhesion prevention, where. Gene therapy represents a promising alternative or complementary approach. These strategies have shown moderate results. Similarly, the transfer of the HGF gene, which promotes mesothelial regeneration, by a viral vector showed a moderate reduction in peritoneal adhesions in a rat model [ ]. However, the presence of side effects indicates the need for a better understanding of the pathways where these molecular targets are involved.
The use of antiadhesive adjuvants offers great potential in the battle against adhesions, and their combination with mechanical barriers or sustained release platforms could enhance their effect and overcome their limitations. More research is needed to assess whether these agents are safe and efficient at preventing postsurgical adhesions alone or in combination with mechanical barriers.
Particularly, more clinical trials are required to prove their safety and efficiency in different surgical procedures. Physical therapy after surgery is a supplementary technique that can improve outcomes and reduce adhesion formation. In flexor tendon surgery, clinicians believe that the early motion of the digits prevents the formation of adhesions with adequate physical therapy; however, the state and strength of the tendon after surgery may limit the application of such therapy [ ].
Early motion eliminates adhesions by physical contact due to the gliding of the tendon [ ], preventing the settlement of adhesions and production of more fibrotic tissue. Some studies in abdominal surgery indicate that manual therapy could be beneficial for adhesion prevention after surgery. Recently, in an in vivo study, Bove et al. The authors suggested a mechanism similar to that in tendons; the motion of organs disrupts initially formed adhesions of deposited fibrin, preventing their settlement.
Additionally, the authors showed a decrease in arginase and CD86 expression by macrophages in treated rats, suggesting the inhibition of the trophic switch of immune cells that subsequently inhibited the activation of fibroblasts. The inhibition of adhesions by visceral mobilisation was previously suggested by the same author [ ]. In humans, manual therapy is employed as a conservative treatment for small bowel obstruction because it promotes its kinetics, but studies that prove the effect of physical therapy on adhesion prevention have been carried out in vivo only.
Since the results obtained in vivo seem to prove that physical therapy is beneficial to prevent adhesions, it could represent a potential complementary treatment in clinics.
Post-surgical adhesions still represent a major complication in most surgeries, with a particular impact on procedures in the peritoneum, uterus, pericardium and tendon where they may result in a serious setback for patients in terms of outcomes, causing pain, reoperation and tissue dysfunction.
Adhesions occur due to an imbalance between fibrin deposition during coagulation and fibrin resolution directed by the fibrinolytic system where both systems maintain a tight relationship with inflammation. Current research on therapies to prevent the formation of adhesions focuses on the use of mechanical barriers and antiadhesive adjuvants. Although serious efforts have been invested, limited positive results have been obtained in the prevention of adhesions, and these results have mostly been shown in animal models.
Therefore, further efforts to understand and develop strategies against the formation of adhesions are needed. The use of combined strategies that involve mechanical barriers, adjuvants such as anti-inflammatories or hormones, and targeted gene therapy appears to be a promising option.
To this end, carrying out blind randomised clinical trials is necessary to assess the safety and confirm the efficacy observed in animal trials of new therapies aimed at addressing the formation of postsurgical adhesions. In addition, the pursuit of new therapies must be synchronised with the development of effective surgical techniques that minimise the risk of their formation.

Risks of adhesions Development of adhesions Symptoms of adhesions Diagnosis of adhesions Treatment of adhesions Where to get help. Risks of adhesions Adhesions may: develop after any kind of pelvic or abdominal surgery — people who have major or multiple procedures are even more at risk cause significantly higher post-operative complications leaks, wound infections, haemorrhages in people with adhesion-related perforations.
This may also lead to a longer stay in hospital lead to other risks and complications, including small bowel obstructions, infertility and chronic pelvic pain cause increased risk, complexity and complications during subsequent surgery.
Development of adhesions Adhesions develop as the body attempts to repair itself. This is the body's normal response after: surgery, particularly abdominal surgery infection endometriosis injury trauma radiation treatment.
Adhesions can also form after inflammation in the abdomen or pelvis. Symptoms of adhesions Although most adhesions are painless and do not cause complications, adhesions cause 60 to 70 per cent of small bowel obstructions in adults and are believed to contribute to the development of chronic pelvic pain.
Symptoms of ARD may include: chronic pain infertility bowel obstruction and an inability to pass gas urinary bladder dysfunction pain and difficulty having a bowel movement pain on movement such as walking, sitting or lying in certain positions emotional disorders such as depression, thoughts of suicide or hopelessness. Diagnosis of adhesions It is very difficult to diagnose the chronic pain of adhesions correctly.
Treatment of adhesions Adhesions can be treated either with open or laparoscopic keyhole surgery, known as adhesiolysis. Open adhesiolysis As adhesions are likely to form after certain surgical procedures, open adhesiolysis may not be worthwhile, except to remedy serious problems such as bowel obstruction.
Laparoscopic adhesiolysis People with symptoms of adhesions may consider laparoscopic surgery. Most women who choose to have laparoscopic adhesiolysis: are discharged on the same day of the procedure don't need to have major abdominal cuts incisions experience minimal complications return to full activity within one week of the procedure.

Her doctors were finally able to solve the mystery of her infertility: Adhesions from a previous cesarean section. Read our daily updates HERE. The body deploys its army of repair cells—including macrophages, fibroblasts and blood vessel cells—to repair the damaged tissue.
Scars can form anywhere on the body after an injury, but adhesions are commonly found in the abdomen, pelvis and heart, and oftentimes interfere with the internal anatomy. Abdominal adhesions form in more than 9 out of 10 people who have open-abdomen surgery, according to the National Institutes of Health. Pelvic adhesions occur in 55 to percent of patients who undergo gynecologic surgery, such as a C-section.
A nearly unavoidable certainty, adhesions also can lead to post-surgical morbidity, bowel obstruction and chronic pelvic pain or chronic abdominal pain.
