6 Hysterectomy

abdominal hysterectomies come in with the low­est risk and have reported averages of 0.11% and
0.35%, respectively [26, 27]. Risk factors include constipation, smoking, immunosuppression, menopausal status, prior pelvic surgery, postop­erative infection, and diabetes.

Prevention

There is no consensus on the best prevention strategy for vaginal cuff dehiscence. Several studies indicate that the incidence has increased after the introduction of laparoscopic and robotic surgery [23], although there is some thought that this may be due to inexperience and that this rate decreases signicantly in experi­enced surgeons’ hands [28]. Some advocate for a two-layer laparoscopic vaginal cuff closure, with one retrospective study showing 0.9% cuff complication rate versus 2.6% in a single-layer technique [25]. Barbed sutures have also been shown in retrospective studies to reduce the risk of dehiscence when compared to non-barbed sutures; however, out of 11 studies looking at this, only 2 found statistical signicance [23]. Another strategy that has been implemented by many institutions has been delayed resumption of intercourse after laparoscopic or robotic cuff closure, our institution uses 9 weeks although data are lacking. The approach to colpotomy has been evaluated by looking at monopolar current versus cut cautery or cold knife, and no studies have been adequately powered to draw conclu­sions [23]. Another prevention technique has been to close the cuff vaginally after a laparo­scopic or robotic procedure. Three studies eval­uating this approach showed an increase in the risk of dehiscence with a transvaginal closure than laparoscopic closure (2.7% vs 1%; p = 0.01) [23, 29]. Some general strategies include adequate mobilization of the bladder to allow adequate cuff to suture, judicious use of cautery to minimize thermal damage, approxi-
mation of the cuff without strangulation, and, in selected cases, vertical closure.

Recognition

A delay in recognition and management can lead to life-threatening complications such as bowel perforation, peritonitis, sepsis, and even death [23]. The presentation includes postcoital bleed­ing, other vaginal bleeding or watery discharge, pelvic pressure or bulge, pelvic pain, and bowel evisceration (Fig.6.6a–c). A high index of suspi­cion is critical with careful history taking and immediate physical examination to visually inspect and manually palpate the vaginal cuff.

Management

Although small or partial dehiscences may be safely managed with pelvic rest, a true vaginal cuff dehiscence is a surgical emergency and war­rants a return to the operating room. If there is any delay in taking the patient to the operating room such as might occur if the patient needs to be transferred from an outside hospital, it should be requested that the patient remain supine or even in slight Trendelenburg with placement of a foley catheter and moist vaginal pack. If bowel is eviscerated, a moist sterile towel should be applied to cover the prolapsed bowel.
Cuff dehiscence can be closed vaginally when possible, but may require abdominal exploration (laparoscopy can be considered) in cases of bowel evisceration to thoroughly inspect the bowel and wash out the peritoneal cavity. If the bowel is able to be inspected vagi­nally, it can sometimes be reduced without trauma. However, if the bowel has become edematous and does not easily reduce, an exploratory laparotomy should be performed. Any necrotic bowel should be resected by a sur­geon trained in bowel surgery.

Intraoperative Injuries

General complications of surgery apply to pelvic reconstructive surgeries as well. Overall, intraop­erative complications are rare; however, it is important to understand how to identify and man­age complications. We will discuss hemorrhage and injury to the urinary tract, gastrointestinal tract, and nervous system specic to the most common pelvic reconstructive surgeries.

Vascular Injury

Background

Hemorrhage related to pelvic organ prolapse sur­gery is uncommon and estimated to be 1.5% [1]. Although rare, excessive blood loss requiring transfusion or formation of a hematoma may occur in any pelvic reconstructive surgery. Hemorrhage risk varies between procedures with the highest risk of severe hemorrhage occurring with sacrospinous ligament xation and sacral colpopexy. The incidence of life-threatening hemorrhage related to sacrospinous ligament xation ranges from 0.2% to 2% [2, 3]. During a

sacrospinous ligament xation, severe hemor­rhage most commonly occurs with dissection superior to the coccygeus muscle or lateral to the ischial spine in the ischiorectal fossa. The infe­rior gluteal artery and its coccygeal branch are most susceptible to injury [4, 5]. During sacro­colpopexy, the mesh is attached to the sacral promontory. This is dened as the most superior point on the anterior surface of S1 into the ante­rior longitudinal ligament. Figure 7.1 demon­strates the presacral space and the proximity of vital structures. The reported hemorrhage or transfusion rate for abdominal sacral colpopexies is 4.4% [6]. There are several potential hemor­rhage sources when dissecting the presacral space including presacral vessels/venous com­plexes, the middle sacral vessels, and the left common iliac vein.

Prevention

As the sacrospinous ligament dissection is typi­cally performed without visualization, hemor­rhage during the procedure may be difcult to control. Since life-threatening hemorrhage is rare, there are few guidelines on how to manage hemorrhage. Utilization of the Capio device or passage of the needle tip downward into the ischiorectal space rather than passing the needle tip superior toward vasculature is preferred [7].

relationship of critical structures to the sacral suture during a robotic sacrocolpopexy [8]. A vascular clip was placed at the level of the sacral suture and 6weeks later, patients under­went imaging to evaluate the anatomy relative to the sacral suture. The left common iliac vein was an average of 26mm away from the sacral suture, while the right common iliac artery was 18mm away. It is important to be mindful of the proximity of these structures when perform­ing the sacral dissection and placement of sacral sutures.
During sacrospinous ligament xation, sudden signicant bleeding may be encountered during the dissection or following placement of the sacrospinous sutures. Hemorrhage is most likely to occur at the time of dissection of the presacral space during sacrocolpopexy. When bleeding occurs at the presacral vessels, hemostasis can be difcult to achieve because of the venous net­work both beneath and on the surface of the peri­osteum. Vessels retract beneath the surface of the anterior sacrum and recede into the bone, includ­ing sacral foramina.

Management

Initial management of hemorrhage includes com­pression of the sacrospinous ligament. This is performed by applying pressure with a sponge on the sacrospinous ligament at the insertion of the ischial spine. Although there is limited evidence on the length of time to hold pressure, a mini­mum compression time of 10min has been sug­gested [9]. If bleeding continues, application of hemostatic agents can be applied. This is most helpful for venous bleeding or capillary oozing. If despite these measures bleeding continues, a narrow malleable or Breisky retractor may be used to attempt visualization of the injured ves­sel. If visualized, suture ligation or placement of vascular clips may be performed. Conversion to laparotomy is not recommended as does not allow for visualization of the hemorrhage source.
Packing of the presacral space may temporar­ily control bleeding, but it may recur once pack­ing is removed. Packing must be done cautiously and without undue pressure to avoid tearing the delicate venous network. Agents for hemostasis may include sutures, metallic clips, cautery, and bone wax. If not successful, stainless steel thumb­tacks can be placed on a retracted bleeding presa­cral vein or into the associated foramen to treat a life-threatening hemorrhage [10]. If performing a laparoscopic or robotic sacrocolpopexy, conver­sion to laparotomy may be performed depending on the vasculature injured, poor control of the hemorrhage, or inadequate visualization.

Urinary Tract Injury

Background

Urinary tract injury at the time of prolapse sur­gery varies depending on the procedure being performed. Cystotomy and ureteral injuries are often diagnosed at the time of surgical proce­dures secondary to the utilization of intraopera­tive cystoscopy [11]. Specic to pelvic reconstructive surgery, the rate of cystotomy is
around 3.2% [12] and ureteral obstruction and/or injury ranges from 0.3 to 11% of cases [13, 14]. Uterosacral ligament suspension (USLS) is the most common procedure associated with ureteral injury [15]. One of the most common complica­tions associated with uterosacral ligament sus­pension is ureteral injury or kinking (risk up to 11% [13]). This risk is high because of ureteral proximity to the uterosacral ligament. The ureter may also be injured directly with the placement of the stitch. This injury is typically identied following the needle placement with leakage of urine into the posterior cul-de-sac. It is often helpful to administer phenazopyridine in the pre­operative period versus methylene blue for easy identication.

Prevention

The ureter is located lateral and ventral to the uterosacral ligament along its course. The dis­tance from the ureter to the uterosacral ligament is estimated to be 0.9cm in the cervical portion,
2.3cm in the intermediate portion, and 4.1cm in the sacral portion. [16] The optimal xation site is the intermediate portion of the uterosacral liga­ment, 1cm posterior to its most anterior palpable margin, at the level of the ischial spine or above [16]. Identication of the uterosacral ligament is paramount in performing this procedure safely. If a USLS is being performed at the time of the vaginal hysterectomy, keeping the ligament tagged at the time of suture ligation is useful to aid in later identication. Adequate visualization of the pelvis is then achieved with the packing of the bowel and use of retractors. An Allis or Babcock clamp may then be placed at the vaginal portion of the uterosacral ligament, and gentle traction is utilized to aide in identication. If this is performed in a patient who is post- hysterectomy, the clamps may be placed at 4 and 8 o clock [17]. The sutures should be placed from ventral to dor­sal, avoiding peritoneum lateral to the ligament, to minimize the risk of ureteral entrapment or kinking.

Recognition

It is imperative to perform an intraoperative cys­toscopy to ensure ureteral patency with these pro­cedures. If ureteral efux is weak or not observed, the suspension on that side should be removed suture by suture with repetitive re-evaluation.

Management

As the ureter is in closest proximity to the utero­sacral ligament distally, the distal suture on the ipsilateral side of the suspension should be removed rst (lateral to medial). The suture can be replaced more medially.

Bowel Injury

Background

Bowel injury during general gynecologic surgery is rare and ranges from 0.13 to 0.54% [18]. The majority of these injuries occur during vaginal or abdominal entry and adhesiolysis [18, 19]. Bowel injuries in pelvic reconstructive surgery are simi­lar, and the same general principles of early diag­nosis and repair apply. Sacrospinous ligament xation and sacrocolpopexy have features that may elicit bowel injury specic to these recon­structive procedures. The global rate of rectal injury during sacrospinous ligament xation is
0.4% [20]. Injury to the rectum is higher if a pre­vious colporrhaphy was performed [21].
The incidence of bowel injury during sacro­colpopexy ranges from 0 to 1.6% [2224]. As with general gynecologic surgery, injuries typi­cally occur with entry. Rectal injury may occur during the development of the rectovaginal space, especially in patients with cul-de-sac adhesions.

Prevention

Although rare, rectal injury is most likely to occur during entry of the ischiorectal fossa while gaining access to the sacrospinous ligament. If
retractors are necessary to aid in visualization of the ligament or to increase the space of dissec­tion, careful placement is necessary to avoid rec­tal injury. This may be accomplished by displacing the rectum with a nger and placing the retractor over your nger.
During sacrocolpopexy, utilization of an endoanal sizer may aid in delineation of the rec­tum and development of the rectovaginal space.

Recognition

A rectal examination should be performed after placement of the sutures because of the close proximity of the rectum to the sacrospinous liga­ment [7].

Management

If a rectal injury is identied during sacrospinous ligament xation, it can be repaired transvaginally.
Limited evidence exists on whether or not a mesh sacrocolpopexy should be completed fol­lowing a bowel injury. A recent review of the lit­erature utilizing the Delphi process recommended that if there is an uncomplicated small bowel injury, the sacrocolpopexy should be completed. If a large bowel injury occurs, the sacrocolpo­pexy should be deferred [25]. Alternatively, con­sideration can be given to completing the procedure with native tissue such as rectus fascia.

Nerve Injury

Background

The incidence of postoperative neuropathy in pelvic surgery is estimated to range from 1.1 to 1.9% [2628]. The procedure with the high­est risk of nerve related injury in prolapse sur­gery is sacrospinous ligament fixation. An estimated 55–84% of patients experience some gluteal or thigh pain immediately postop [29,

30]. This decreases to around 3–16% by
6weeks [2, 29, 30].
Although rare, nerve injuries can occur with USLS [31]. There have been conicting literature describing the anatomy of the uterosacral liga­ments. Several studies have demonstrated that the uterosacral ligaments insert directly into the sacrum [16, 32], while others have demonstrated that most of the ligaments insert into the sacro­spinous and coccygeus muscle complex [33]. Cadaveric studies have demonstrated that entrap­ment of S1–S4 nerves is most likely implicated in neuropathic pain after USLS [3436].

Prevention

Postoperative pain is secondary to the proximity of the sciatic nerve to the sacrospinous ligament. Cadaver studies have demonstrated that branches from S3 and/or S4 course between the sacrospi­nous and sacrotuberous ligaments and are most likely to be affected in this procedure [37]. Figure 7.2 demonstrates the sacrospinous liga­ment and the proximity to vital structures. To minimize entrapment, it is recommended that the
sutures be placed 2–3cm from the ischial spine at the mid-section of the ligament [38].
The anatomic studies also indicate that there may be signicant variability in the anatomy of the uterosacral ligament. One theory is that nerve entrapment most likely occurs when the utero­sacral suture is placed too lateral and deep [31].

Recognition

Nerve injury at the time of pelvic reconstructive surgery is rare and is typically not diagnosed in the operating room. Injuries are identied post­operatively based on patient symptoms. If there is severe or persistent pain following a sacrospi­nous ligament xation, this may indicate a puden­dal nerve entrapment. USLS nerve entrapment from the S1 to S4 distribution may include sharp pain radiating from the buttocks into the posterior leg, resulting in difculty sitting and walking [39].
Nerve injuries related to position should be considered in any surgery. For pelvic organ pro­lapse surgery, the patients are positioned in the dorsal lithotomy or high lithotomy position. The

most common injuries include the common pero­neal and femoral nerves. Positional injuries may be avoided by ensuring padding over bony prom­inences and avoiding excessive exion and exter­nal rotation of the hip.

Management

In such instances, prompt suture removal should be considered [40]. Uterosacral nerve entrapment may be managed similarly to that of sacrospinous neuropathy. Conservative management may include physical therapy, stretching exercises, and medical management with neuroleptics, such as Gabapentin. If not alleviated by conservative management, surgical intervention with suture removal should be considered.

Postoperative Considerations

Postoperative complications of pelvic recon­structive surgery are rare and may consist of infection, urinary retention, bleeding, and pain. For the purposes of this chapter, we will discuss specic complications in the most common pro­lapse surgeries.
The treatment of mesh complications is unique in pelvic reconstructive surgery. Mesh complica­tions may include exposure, pain, dyspareunia, infection, and erosion. The mesh exposure rate for abdominal sacrocolpopexy is estimated to be 3% [41]. If mesh exposures are less than 0.5cm and the patient is asymptomatic, they may be managed with topical estrogen or observation. If the patient is symptomatic, the exposure is per­sistent, or a multilament mesh was used, removal is recommended [42]. Typically, vaginal excision of the visualized mesh may be per­formed. If infected, the recommendation is for the removal of the entire mesh. If there is concern for an infection, a pelvic MRI to evaluate the entire length of the mesh and the sacral promon­tory is recommended. If a patient complains of persistent back pain, an MRI to evaluate the promontory should be performed to evaluate for osteomyelitis. While the incidence is less than
1/1000 sacrocolpopexy cases [43], the sequelae from this can be devastating. Mesh erosion into the bowel or bladder is extremely rare and is typi­cally managed with an interdisciplinary team depending on the organ affected.
Reperitonealization following sacrocolpopexy is often recommended to hypothetically prevent small bowel obstruction. Recent studies have found that bowel complications are similar in women who undergo reperitonealization of mesh versus those who do not [44, 45].

Prolapse Recurrence

Approximately 11% of women will undergo sur­gery for prolapse or stress urinary incontinence in their lifetime [46]. Unfortunately, one of the most common complications related to prolapse repair is recurrent prolapse. Reoperation for pro­lapse recurrence ranges from 2.2 to 4.4% for sacrocolpopexy [47, 48] and 3–6.5% for native tissue repair [49, 50] at 2years postoperatively. Epidemiologic studies report that a 20-year risk of repeat operation is 11% overall with younger (<50years of age) women having higher risk of repeat surgery compared to women >/= 50 (26.9% vs.10.1%) [51]. Recurrent prolapse as measured by POPQ criteria is more common after native tissue than mesh augmented repairs, such as sacrocolpopexy. Dened as recurrent stage 2 prolapse on pelvic examination, an esti­mated 23% of women have recurrent prolapse after sacral colpopexy and around 41% after native tissue procedures at 1–2years following surgery [41]. Although the recurrence rate is higher in native tissue procedures, this risk is bal­anced against the risk of mesh complications.

Conclusion

Pelvic reconstructive surgery procedures are gen­erally low risk with low morbidity. The most common complication is recurrence of prolapse. Other complications of these surgeries are rare, although if not managed appropriately can be catastrophic.
