Keywords: vaginal evisceration; vaginal cuff dehiscence; complications after hysterectomy; long-standing pessary
Background: Intestinal loop evisceration complicates 35-67% of vaginal cuff dehiscence, constituting a medical emergency. In most cases, it is associated with genital prolapse in postmenopausal women with previous hysterectomy. Complications associated with the use of a pessary are rare. They are usually due to loss of patient follow-up or negligent use of the device.
Clinical presentation: We present the case of a 94-year-old patient who debuted with vaginal evisceration after vaginal cuff dehiscence, associated with prolonged use of pessary as a treatment for vaginal cuff prolapse and enterocele, after laparotomic hysterectomy. Vaginal repair was performed abdominally, due to the size and condition of the eviscerated loops, requiring intestinal resection. An omentum flap was attached to the vaginal cuff to improve healing and to try to occlude the Douglas space.
Conclusions: EV requires vaginal, abdominal, or mixed repair, generally deferring definitive prolapse treatment to a second stage and we recommend being very careful with the closure of the vaginal vault after any type of hysterectomy

The vaginal cuff dehiscence (VCD) is the partial or complete separation of the anterior and posterior walls of the vaginal incision after a Hysterectomy. It can be complicated by evisceration (VE), defined as the expulsion of intraperitoneal contents through this vaginal incision. Most commonly, this involves parts of distal ileum, but also omentum, appendix or fallopian tubes, and two cases of colon evisceration have been published [1].
The incidence of VCD ranges from 0.14% to 4.1%, depending on the type of hysterectomy performed. Higher rates are reported after laparoscopic or robotic hysterectomy than after all other surgical techniques together [2].
VE complicates 35-67% of VCD, constituting a medical emergency. This event can generate complications, such as intestinal ischemia, sepsis and venous thrombosis [3]. 20% of patients will require bowel resection [4], 15% will have postoperative complications, and the mortality rate reaches 6% [3].
In most cases, VE due to VCD is associated with genital prolapse in postmenopausal women with previous hysterectomy [2].
On the other hand, complications associated with the use of a pessary to treat genital prolapse are rare. They are usually due to loss of patient follow-up or negligent use of the device. VCD, VE and vesico-vaginal or recto-vaginal fistulas are the main complications described [5].
We present the case of a 94-year-old patient with VE after VCD, associated with prolonged use of pessary as a treatment for vaginal cuff prolapse and enterocele, after total laparotomic hysterectomy.
Clinical Presentation
A 94-year-old patient came to the hospital emergency room for insidious onset abdominal pain in the previous days which suddenly became severe during the last 2 hours. She presented scant vaginal bleeding the day before The anamnesis was almost impossible due to her state of severe agitation because of the pain. As a medical history, she had hypertension, anxiety-depressive syndrome and cognitive impairment. She also had two vaginal deliveries, menopause around the age of 50 and abdominal hysterectomy (indicated by prolapse) associated with cholecystectomy at the age of 60. Subsequently, she suffered a recurrence (vaginal vault prolapse and enterocele) that was treated with a vaginal pessary for the last 8 years. Her last gynecological examination with pessary replacement was 6 months before the episode.
During the medical examination in the lithotomy position, it was striking the leakage of the intestinal contents outside the vulvar plane, with an intense red mesentery and signs suggestive of ischemia (Figure 1).
On palpation, the abdomen was soft, but painful and with signs of peritoneal irritation. It wasn’t possible vaginal examination to determine whether or not carrying the pessary.
Blood analysis revealed leukocytosis (18.66 x 10ˆ3/µL) with a left deviation (92.7%) and increased glucose (214 mg/dL) and protein C reactive (PCR 35 mg/L). The rest of the parameters were normal: hemoglobin, hematocrit, sodium, potassium, creatinine and coagulation.
We contacted the General Surgery Service and a joint assessment of the patient was carried out; Urgent surgery was indicated due to the ischemic state of the intestinal loops, which was performed after receiving a negative PCR-Covid19 result. While the patient was transferred to the operating suite, the eviscerated intestinal contents were wrapped with moistened gauze in warm physiological saline solution; Intravenous broad-spectrum antibiotic therapy (amoxicillin-clavulanic acid 1 g/8 h) was started.
A subumbilical midline laparotomy was performed, releasing multiple intestinal adhesions.
After reaching the pelvis, the prolapsed intestinal content in the vagina was manually reduced. The vaginal pessary located in the posterior vaginal fornix was removed and the dehiscence of the vaginal vault was observed, with an extension of 3 cm.
The vagina was sutured by abdominal way, with late resorption thread (0/0), with continuous and double suture, 1 cm from the vaginal edge. It didn’t require debridement of the edges given its good appearance.
After this vaginal repair, the intestinal loops reintroduced to the abdomen were reviewed, showing a necrotic plaque and intense edema with signs of intestinal ischemia (Figure 2), which required the resection of 40 cm of the distal ileum.
Finally, an omentum flap was approximated to the Douglas space, to suture it without tension to the vaginal cuff, with the intention of reinforcing the vaginal suture, given the characteristics of the patient (94 years and prolonged menopause).
The immediate postoperative period was favorable and on the seventh day the patient was discharged from the hospital.
The first gynecological examination was carried out at 3 months, verifying that there is no vaginal cuff prolapse or enterocele. New visits were scheduled; if the prolapse recurred, a new pessary would be avoided, recommending obliterative surgery in this patient.
Historically, the majority of VCD cases were reported after vaginal hysterectomy, but distribution has changed with increasing laparoscopic hysterectomy. Possible factors are speculated: the surgeon's experience, errors in the technique, the lower safety of the stitches, the magnification of the image that would lead to sutures closer to the edges of the vaginal cuff and with less tissue, and the colpotomy performed with electrosurgery (thermal damage) [2].
Currently, the majority of VCD are associated with prolapse in postmenopause with a previous history of pelvic surgery. Especially when chronic medical conditions that transfer intra-abdominal pressure coexist such as cough, asthma, gastroesophageal reflux and chronic constipation [2].
Other risk factors related to VCD, in addition to menopause, due to vaginal atrophy, and hysterectomy are:
If there is an enterocele, the anatomy of the vaginal cuff is modified, which associated with atrophy, increases the risk of dehiscence with increased intra-abdominal pressure. In addition, in cases of severe vaginal cuff prolapse, venous stasis and pressure ulcers may appear [2].
In a premenopausal woman, the risk of vaginal cuff dehiscence with evisceration is low but is most frequently associated with vaginal trauma from early coitus after hysterectomy, a foreign body or gynecologic instrumentation [2].
Evisceration of the intestine through a VCD constitutes a surgical emergency. The most common symptoms are pelvic pain (58-100%), vaginal bleeding (23.5-90%), vaginal discharge (55.6%), and signs of infection or peritoneal irritation [2].
The approach for surgical repair will depend on the clinical stability of the patient and the eviscerated bowel viability. In cases involving medical stable patients with a small amount of gutted intestine, without evidence of peritonitis or necrotic bowel, a vaginal approach could be performed [12], even associated with laparoscopy for inspection of intestinal loops. This mixed approach occurs in less than 15% of cases of VE [4]. Even the omentum can be identified in the vagina and reduced to the abdomen at the vaginal closure [4].
The rest of the clinical presentations must be repaired by transabdominal approach (laparoscopic or laparotomic) especially in cases of clinical or hemodynamic instability, large amount of eviscerated intra-abdominal content and suspected ischemia or incarceration/strangulation [3, 5].
The surgery will include vaginal closure, revision of intestinal loops reintroduced into the abdomen and possible resection in up to 20% [4].
A definitive concomitant treatment of the prolapse is generally not applied, given the emergency of the process, but can be planned a posteriori [13]. Depending on the age and characteristics of the patient, the approach to the prolapse could be through repair surgery with sacrocolpopexy or fixation to the sacrospinous ligament, or obliterative surgery with colpocleisis.
Many types of vaginal repair have been reported with the aim of improving the closing conditions of the cuff and preventing recurrence of VCD with evisceration. They described below:
In our case, VCD was associated with obesity, menopause, hysterectomy, vaginal cuff prolapse and enterocele, and use of pessary for 8 years (with adequate follow-up and last replacement 6 months before) as risk factors. During the surgical procedure, the pessary was found attached to the posterior vaginal wall. This may suspect that the enterocele altered vaginal angulation, which, associated with atrophy and increased intra-abdominal pressure, caused the rupture of the vaginal suture. The surgical repair way was abdominal due to the patient's clinical condition (severe pain with laboratory involvement) and the state of the eviscerated bowel, which would probably require surgical resection.
Presurgical management was carried out according to updated bibliographic recommendations [12,13], in relation to wrapping the intestinal loops with compresses soaked in warm physiological saline and initiating broad-spectrum prophylactic antibiotic therapy.
Before cuff repair, the need to debride the cuff edges was assessed, as indicated by some publications [2, 3], but it was not necessary due to the absence of signs of necrosis or infection.
The cuff closure was performed with continuous double layer suture (0/0), 1 cm from the edge of the cuff, technique that appears to be protective with respect to the recurrence of VCD [2].
Given the age of the patient, 94 years and her clinical emergency status, definitive treatment for the prolapse was not performed; the use of synthetic meshes was not considered either. An omentum flap was released to fix it to the vaginal vault, with the double intention of occluding the Douglas space (and avoid enterocele) and improve vascularization during healing.
Rubin et al., in an 82-year-old patient with VCD and VE after vaginal histerectomy at the age of 72 and continued use of a pessary, performed the inspection of the intestinal loops by laparotomy and concomitant treatment of prolapse with colpocleisis [5].
Other authors have published cases of VE after pessary use, associated with menopause, vaginal and abdominal hysterectomy [5]. In 1976, Thiele described a case of VCD and VE after negligent use of the pessary for 4 years without revisions [17].
When genital prolapse is corrected with a pessary, in addition to selecting the size properly, patients and their caregivers should be instructed in its correct management. Pessary designs and materials could be improved and consultation time should be devoted to teaching insertion and removal techniques at home.
On the other hand, a review regarding the use of vaginal estrogens to prevent VCD, both before and after hysterectomy, are not conclusive [13].
