<\/span>Introduction<\/span><\/h2>\n\n\n\nHysterectomy remains one of the most commonly performed gynecologic surgeries worldwide, with an estimated 600,000 procedures conducted annually in the United States alone. Approaches include total abdominal hysterectomy (TAH), vaginal hysterectomy (VH), laparoscopic hysterectomy (LH), and robotic-assisted hysterectomy (RH). The procedure can be completed with or without salpingo-oophorectomy, and may be assisted by laparoscopy (LAVH) or performed totally via laparoscopy (TLH).<\/p>\n\n\n\n
Iatrogenic injuries\u2014injuries inadvertently caused by surgical intervention\u2014are a well-recognized complication of hysterectomy. These complications can affect the urinary tract (bladder and ureters), gastrointestinal tract (bowel and rectum), vasculature, and nerves, and may lead to significant morbidity if not promptly detected and managed.<\/p>\n\n\n\n
This report synthesizes current evidence regarding the types, frequencies, and causes of iatrogenic injuries in hysterectomy procedures, with a special focus on laparoscopic-assisted vaginal hysterectomy with bilateral salpingo-oophorectomy (LAVH + BSO). The report also outlines preventive measures and recommendations to minimize these injuries.<\/p>\n\n\n\n
<\/span>General Hysterectomy Injuries<\/span><\/h2>\n\n\n\n<\/span>Urinary Tract Injuries<\/span><\/h3>\n\n\n\nUrinary tract injuries are among the most frequent iatrogenic complications of hysterectomy, occurring in 0.3%\u20131%<\/strong> of gynecologic surgeries. Bladder injuries are reported in 0.5%\u20130.66%<\/strong> of cases, while ureteral injuries range from 0.02%\u20130.4%<\/strong> in LH and TLH procedures. Abdominal hysterectomy carries ureteral injury rates of 0.03%\u20132%<\/strong> and bladder injury rates of 0.2%\u20131.8%<\/strong>. Vaginal hysterectomy is associated with lower ureteral injury rates (0.9% vs. 1.7%<\/strong> in abdominal hysterectomy) but this risk increases to 2.6%<\/strong> when performed with pelvic floor reconstruction.<\/p>\n\n\n\n<\/span>Common mechanisms include<\/span><\/h3>\n\n\n\n\n- Misidentification of anatomy leading to ligation or transection of the ureter near the uterine artery or within the parametrial tunnel.<\/li>\n\n\n\n
- Thermal injury from electrosurgery (monopolar or bipolar cautery), resulting in late-onset ureteral strictures or fistulae.<\/li>\n\n\n\n
- Mechanical trauma during trocar or instrument insertion, especially when creating the pneumoperitoneum or during adhesiolysis.<\/li>\n\n\n\n
- Delayed diagnosis \u2014 often absent until 7\u201310 days postoperatively \u2014 which can present with flank pain, fever, peritonitis, or urinary leakage and is associated with higher morbidity including urinary fistula and loss of renal function.<\/li>\n<\/ul>\n\n\n\n
<\/span>Gastrointestinal Injuries<\/span><\/h3>\n\n\n\nBowel injuries occur in approximately 0.1%\u20130.2%<\/strong> of hysterectomy cases, with the small intestine most frequently involved (47%<\/strong> of cases in laparoscopic gynecologic procedures).<\/p>\n\n\n\n<\/span>Mechanisms include<\/span><\/h3>\n\n\n\n\n- Trocar or Veress needle misplacement during abdominal access (up to 55%<\/strong> of bowel injuries).<\/li>\n\n\n\n
- Thermal injury to serosa or full-thickness bowel walls from electrosurgical dissection in areas of poor visualization.<\/li>\n\n\n\n
- Adhesion-related tears during blunt dissection in patients with prior surgeries or endometriosis.<\/li>\n\n\n\n
- Delayed recognition \u2014 occurring in 41%<\/strong> of bowel injuries \u2014 can be lethal; unrecognized injuries have a mortality rate of 3.2%<\/strong> (five deaths in 154 delayed diagnoses).<\/li>\n<\/ul>\n\n\n\n
<\/span>Vascular Injuries<\/span><\/h3>\n\n\n\nAlthough rare, vascular injuries can have catastrophic consequences. Reported incidences include:<\/p>\n\n\n\n
\n- Major vessel laceration during trocar insertion or adhesiolysis (reported 1.3%<\/strong> in LH in retrospective surveys).<\/li>\n\n\n\n
- Vascular injuries often involve pelvic sidewall vessels and may require immediate laparotomy, vascular repair, or transfusion.<\/li>\n<\/ul>\n\n\n\n
<\/span>Nerve Injuries<\/span><\/h3>\n\n\n\nPeripheral nerve injuries are uncommon but can occur from patient positioning in steep Trendelenburg and lithotomy positions. Incidences range from 0.25%\u20132%<\/strong> in LH\/RH procedures.<\/p>\n\n\n\n<\/span>Common injuries include<\/span><\/h3>\n\n\n\n\n- Brachial plexopathies and ulnar nerve palsies from arm abduction >90\u00b0 and inadequate shoulder padding.<\/li>\n\n\n\n
- Obturator and femoral nerve injuries from prolonged lithotomy position and insufficient leg support padding.<\/li>\n<\/ul>\n\n\n\n
<\/span>Other Complications<\/span><\/h3>\n\n\n\n\n- Wound infection: superficial incisional infection rates of 2.3%\u20132.6%<\/strong> after abdominal hysterectomy and 0.6%\u20130.8%<\/strong> after laparoscopic hysterectomy.<\/li>\n\n\n\n
- Deep incisional\/organ-space infection: 0.5%\u20131.2%<\/strong> across all routes, including vaginal cuff cellulitis and pelvic abscess formation.<\/li>\n\n\n\n
- Febrile morbidity: 3%\u201350%<\/strong> depending on antibiotic prophylaxis and patient profile.<\/li>\n\n\n\n
- Venous thromboembolism: 0.3%\u20131%<\/strong> risk of DVT or pulmonary embolism in major pelvic surgery, reduced by prophylaxis protocols.<\/li>\n\n\n\n
- Vaginal cuff dehiscence: 0.14%\u20131.14%<\/strong> with higher rates in TLH, often related to early coitus and delayed healing.<\/li>\n\n\n\n
- Conversion rates: 2.7%\u20137.5%<\/strong> for TLH and LAVH procedures, mainly due to adhesions or uncontrolled bleeding.<\/li>\n<\/ul>\n\n\n\n
<\/span>Injuries Specific to LAVH with Salpingo\u2011Oophorectomy<\/span><\/h2>\n\n\n\n<\/span>Urinary Tract Injuries in LAVH + BSO<\/span><\/h3>\n\n\n\nRobotic-assisted and standard laparoscopic data reveal similar urologic injury rates:<\/strong><\/p>\n\n\n\n\n- Robotic hysterectomy: 0.92%<\/strong> urologic injury rate (0.6% bladder, 0.32% ureter) in 1,088 cases.<\/li>\n\n\n\n
- Laparoscopic hysterectomy: 0.90%<\/strong> urologic injury rate in 782 cases.<\/li>\n\n\n\n
- Vaginal hysterectomy: 0.33%<\/strong> urologic injury rate in 304 cases.<\/li>\n\n\n\n
- Open abdominal hysterectomy: 0.96%<\/strong> urologic injury rate in 940 cases.<\/li>\n<\/ul>\n\n\n\n
Risk factors such as high BMI (>34 vs. 32) were not statistically significant for injury risk in this cohort.<\/p>\n\n\n\n
<\/span>Gastrointestinal Injuries in LAVH + BSO<\/span><\/h3>\n\n\n\nBowel injury rates during LAVH + BSO remain low (0.2%<\/strong>) with major complications often attributed to:<\/p>\n\n\n\n\n- Adhesiolysis in patients with prior C-sections or peritonitis.<\/li>\n\n\n\n
- Thermal spread from energy devices used to control pelvic sidewall vessels.<\/li>\n\n\n\n
- Immediate laparoscopic repair can be successfully performed if injuries are recognized intraoperatively.<\/li>\n<\/ul>\n\n\n\n
<\/span>Vascular and Nerve Injuries in LAVH + BSO<\/span><\/h3>\n\n\n\nVascular injuries during LAVH + BSO are rare (\u22481.2%<\/strong>), but can occur during infundibulopelvic ligament division. Nerve injuries (0.4%\u20130.6%<\/strong>) are often related to steep Trendelenburg and prolonged operative times in advanced laparoscopic cases.<\/p>\n\n\n\n<\/span>Case Reports and Unique Repair Techniques<\/span><\/h3>\n\n\n\nRectal perforation repair using an endoscopic stapler without diversion was reported in TLH + BSO, demonstrating feasibility when recognized intraoperatively and proper bowel preparation was performed.<\/p>\n\n\n\n
<\/span>Preventive Measures<\/span><\/h2>\n\n\n\n<\/span>Preoperative Strategies<\/span><\/h3>\n\n\n\n\n- Risk stratification:<\/strong> Identify patients at high risk for urinary or bowel injury\u2014prior C-sections, endometriosis, pelvic malignancies\u2014using imaging (ultrasound, IVU, CT).<\/li>\n\n\n\n
