In reality, clinical studies indicate that approximately 93% <sup>[i]<\/sup> of patients may develop postoperative adhesions following abdominal surgery, regardless of surgical technique. Severe adhesions may lead to chronic pain, bowel obstruction, or infertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Postoperative adhesions are difficult to predict\u2014not only whether they will occur, but also when they may develop. Therefore, prevention remains more effective than treatment. Particularly in minimally invasive procedures, where the operative field is limited, selecting an appropriate anti-adhesion adjunctive device with practical surgical usability has become increasingly important.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\">Why Can Adhesions Still Occur After Minimally Invasive Surgery?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Adhesion formation is a natural response during tissue healing and can occur throughout the body, most commonly after abdominal or pelvic surgery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the peritoneum or organ surfaces are injured, damaged tissues release fibrin, which functions like a biological glue to repair wounds. During this healing process, surrounding tissues or organs may unintentionally stick together, leading to adhesion formation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although minimally invasive surgery involves smaller incisions, it still creates peritoneal trauma that activates the body\u2019s repair mechanisms. As a result, the risk of postoperative adhesions remains present. Additionally, minimally invasive procedures frequently rely on electrosurgical instruments, which may cause thermal injury to surrounding tissues and further increase inflammation and adhesion risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adhesions are generally irreversible. In severe cases involving bowel obstruction, chronic pain, or infertility, additional surgery may be required for adhesiolysis. Therefore, physicians and patients are encouraged to discuss adhesion prevention strategies before surgery, including the possible use of anti-adhesion barrier devices to support long-term postoperative quality of life.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\">The Evolution of Anti-Adhesion Medical Devices<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To reduce adhesion-related complications, anti-adhesion barrier technologies have continuously evolved alongside surgical advancements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Several types of anti-adhesion materials are currently used in clinical practice, each with distinct characteristics and applications.<\/p>\n\n\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-b6c2672\" data-block-id=\"b6c2672\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-b6c2672-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-4a633bb\" data-v=\"4\" data-block-id=\"4a633bb\"><style>@media screen and (min-width:690px){.stk-4a633bb {flex:var(--stk-flex-grow, 1) 1 calc(5% - var(--stk-column-gap, 0px) * 2 \/ 3 ) !important;}}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-4a633bb-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-4a633bb-inner-blocks\"><\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-e60a064\" data-v=\"4\" data-block-id=\"e60a064\"><style>@media screen and (min-width:690px){.stk-e60a064 {flex:var(--stk-flex-grow, 1) 1 calc(85% - var(--stk-column-gap, 0px) * 2 \/ 3 ) !important;}}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-e60a064-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-e60a064-inner-blocks\">\n<figure class=\"wp-block-table is-style-regular\" style=\"font-size:14px\"><table class=\"has-soft-grass-gradient-background has-background has-fixed-layout\" style=\"border-width:3px\"><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Type<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Materials \/ Mechanism<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Characteristics<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Clinical Application Scenarios<\/strong><\/td><\/tr><tr><td>Solid Barrier Films<\/td><td>Hyaluronic acid, Carboxymethylcellulose (CMC), etc.<\/td><td>Directly covers localized wounds to form a physical barrier.<\/td><td>Suitable for traditional open surgeries. The confined space in minimally invasive surgery creates a very high technical threshold for application. Additionally, it is less suitable for large or irregular wounds.<\/td><\/tr><tr><td>Gel-Type Barriers<\/td><td>Hyaluronic acid derivatives, Cross-linked peptide hydrogels.<\/td><td>Easier to apply than films; can cover localized, irregular areas.<\/td><td>More suitable for minimally invasive surgeries with small, irregular wounds.

During this period, organs remain temporarily separated, reducing fibrin bridge formation between tissues.<sup>[ii]<\/sup><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>1. Gynecologic Surgical Applications<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">According to U.S. FDA-approved information, 4% icodextrin solution may be used as an adjunctive device to reduce postoperative adhesion risk following gynecologic laparoscopic surgery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common clinical applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Endometriosis surgery<\/li>\n\n\n\n<li>Ovarian cystectomy<\/li>\n\n\n\n<li>Pelvic adhesiolysis<\/li>\n\n\n\n<li>Management of multiple peritoneal injuries<\/li>\n\n\n\n<li>Deep pelvic minimally invasive surgery<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>2. General Surgery and Colorectal Surgery<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Because the intestines are highly mobile within the abdominal cavity, broad anti-adhesion protection may be beneficial in procedures involving extensive bowel manipulation or prior abdominal surgeries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clinical situations may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Severe bowel adhesion separation surgery<\/li>\n\n\n\n<li>Patients with previous abdominal surgery history and recurrent bowel obstruction risk<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>3. Trauma and Extensive Abdominal Surgery<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Liquid anti-adhesion solutions may also be considered in emergency surgeries involving major abdominal trauma, blunt injury, or intra-abdominal bleeding.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\">Choosing Anti-Adhesion Devices Should Be Individualized<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Currently, no single anti-adhesion product is suitable for every surgical scenario.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Different barrier materials possess unique physical characteristics and clinical indications. Product selection should not rely solely on cost considerations. Instead, physicians and patients are encouraged to discuss surgical approach, operative complexity, and individual risk factors before determining the most appropriate adhesion prevention strategy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As minimally invasive surgery continues to evolve, anti-adhesion technologies are also advancing toward solutions that better address complex anatomy and surgical practicality. For procedures requiring broad coverage and deep pelvic protection, liquid anti-adhesion solutions remain an important option in modern minimally invasive surgery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.313), 18px);\"><strong>Disclaimer:<\/strong><br>This article is intended for educational and informational purposes only and does not constitute medical advice.
