Introduction

Radical hysterectomy is an extended hysterec­tomy that is intended to remove the uterus as well as a variable amount of soft tissue, for the pur­pose of achieving appropriate oncologic resec­tion of a pelvic malignancy. While mainly utilized as primary surgical treatment of early stage cervi­cal cancer, this operation may also be incorpo­rated into the surgical management of extended operations for ovarian, colorectal or urologic malignancies.
When utilized to treat cervical cancer, radical hysterectomy includes surgical assessment of the pelvic and sometimes paraaortic lymph nodes. Pelvic and paraaortic lymphadenectomy is cov­ered in Chap. 32. When performed as a primary operation for cervical cancer, the oncologic mar­gins include the endopelvic fascia ventrally, the lymph node-bearing tissue associated with the uterine vessels as well as the paravaginal portion

of the cardinal ligament laterally, the uterosacral and rectovaginal ligaments dorsally, and the upper vagina distally. Resection of this addition soft tissue requires extensive mobilization of the distal ureters and bladder from the cervix and upper vagina. The upper rectum must be sepa­rated from the upper vagina. Variations of this operation are performed to resect other pelvic malignancies, depending on their extent. Radical hysterectomy may be performed by open or lapa­roscopic surgery.
Major complications of radical hysterectomy include urinary tract injury, bladder dysfunction, rectal injury, colorectal dysfunction, vaginal dehiscence, surgical site infection and sexual dysfunction.

Ureteral Injury

Background

Freeing the ureter from its course through the parametria (Fig.33.1) is a major part of the effort in performing a radical hysterectomy. The extent of ureteral dissection varies according to the radi­cality of the operation, but invariably results in some loss of ureteral vasculature.
The incidence of ureteral injury (immediate and delayed) is reported to be 1–2% [117]. The risk is much higher in those who have received prior pelvic radiotherapy [18, 19].

Prevention

Thorough knowledge of the surgical anatomy of the pelvic ureter is a critical factor in the safe per­formance of a radical hysterectomy. There must be gentle, meticulous dissection of the ureter with avoidance of thermal energy in proximity to this structure. It is the opinion of the authors that stents may have a deleterious effect during radi­cal hysterectomy by making the ureters stiff and more susceptible to shearing of feeder vessels and the adventitia.
The degree of ureteral dissection will vary according to the radicality of the hysterectomy, which should be tailored to an oncologically appropriate resection (Fig.33.2). Regardless, it is of paramount importance that the integrity of the ureteral adventitia be preserved and that dis­section lateral to the distal most aspect of the ureter be avoided (Fig. 33.3) [1]. Finally, for
Course of
women who have received prior full dose radio­therapy, radical hysterectomy that will involve anything beyond minimal ureteral dissection should only be considered in highly selected cases [18, 19].

Recognition

During radical hysterectomy, the surgeon must maintain a high level of vigilance with the ure­ters, both during dissection and resection. Thermal damage may not be readily appreciable and any concern regarding this possibility must be managed accordingly. Loss of adventitia is equally concerning. Clear uid appearing in the operative eld must be investigated with careful inspection, aided by intravenous injection to dye the urine. Cystoscopy with the passage of a stent and/or retrograde pyelography are also options.

injury, as well as to look for the presence of a urinoma. Unfortunately, the silent death of a kid­ney secondary to obstruction is a well-known phenomenon.

Management

This is covered in detail in Chap. 17. Briey, the vast majority of ureteral injuries that are recog­nized intraoperatively are managed with a ure­teroneocystostomy. For minimal damage (loss of a small area of adventitia) or suspected mild injury (questionable mild thermal insult), ureteral stenting alone may be considered. For manage­ment of an injury diagnosed postoperatively, please refer to Chap. 17.

Background

During radical hysterectomy, the bladder must be mobilized to a much greater extent than required for a simple hysterectomy. This is necessary to achieve adequate vaginal and parametrial margins. The incidence of bladder injury associated with radical hysterectomy is up to 4% [17, 20, 21]. Signicantly, some of these injuries are close to the trigone due to the need for more distal dissection.
Due to the oncologic importance of maintaining the integrity of the endopelvic fascia with the spec­imen, it is not appropriate to direct dissection away from the bladder and into the cervix or vagina. Prevention of injury requires cautious dissection, including the lateral aspects of the bladder that might otherwise be damaged during paravaginal resection. Backlling the bladder is occasionally useful in challenging cases. Minimal and judicious use of thermal injury is important here.

Recognition

As with the ureters, the surgeon must maintain a high level of vigilance with the bladder, both dur­ing dissection and resection. Similarly, thermal damage may not be readily appreciable and any concern regarding this possibility must be managed accordingly. Clear uid appearing in the operative eld must be investigated with care­ful inspection, aided by backlling the bladder under observation.
Following surgery, a bladder injury may pres­ent within days or weeks depending on the mech­anism of the insult. As with the ureter, thermal injury tends to be more delayed. Large volume clear drainage from the vagina is concerning and is initially evaluated by backlling the bladder with a dyed solution while observing the vaginal cuff with a speculum. A CT urogram is the deni­tive test to evaluate for and dene the location of a bladder injury, and to look for a concomitant ureteral injury and/or urinoma.

Management

This subject is covered in detail in Chap. 12. Following a radical hysterectomy, bladder sensa­tion is often impaired. An overdistended bladder may lead to failure of repair of even a minor injury. This requires special consideration when determining the length of time for postoperative bladder rest.

Prevention

Identication and incision of the rectal reection must be accomplished, followed by maintaining the correct path of dissection in the rectovaginal space and off of the rectovaginal ligaments. This may be challenging in cases of Pouch of Douglas obliteration (endometriosis, diverticulitis). An instrument in the rectum such as an EEA sizer may occasionally be useful in challenging cases. Judicious use of thermal energy is a must when in proximity to the rectum.

Recognition

As with the previously discussed urinary tract injuries, constant vigilance is required during dis­section and resection if the surgeon is to recog­nize this uncommon intraoperative complication. Stool in the eld or noting the rectal lumen makes the injury apparent. Sudden loss of resistance during development of the rectovaginal space should lead to prompt investigation for this pos­sibility. When any level of concern exists, the “air bubble” or “at tire” test is useful in ruling a rec­tal injury in or out.
With delayed injury, the patient will almost always present with stool per vagina. Examination and a contrast enema will be conrmatory.

Management

Rectal Injury

Background

During radical hysterectomy, it is necessary to mobilize the rectum from the upper vagina and medial aspect of the rectovaginal ligaments in order to obtain appropriate margins. Injury of the rectum may occur during dissection or resection. Injury of the rectum (immediate or delayed) is uncommon and underreported. However, it is presumed to be comparable to benign hysterec­tomy where it has been shown to occur in less than 1% of cases [17, 22, 23].
A rectal injury identied at the time of surgery is temporarily closed to reduce contamination while the hysterectomy is completed. After controlled irrigation, the defect is closed in two layers as described in several other chapters.
When presenting as a delayed rectal injury, diversion is required followed by later repair.

Bladder Dysfunction

Background

Radical hysterectomy partially denervates the bladder (Fig. 33.4). Following radical hysterec-

tomy, a majority of patients experience some degree of lower urinary tract dysfunction, although the reported incidence varies greatly in the literature [15, 2439]. The most common morbidity related to the extent of radicality is lower urinary tract dysfunction [12, 15, 4044]. This is mainly a short-term difference (rst 3months) although the infrequent occurrence of long-term (greater than 6–12 months) severe voiding dysfunction also appears to be greater with the Class III operation (Fig.33.2) [13, 14]. The pathophysiology of lower urinary tract dys­function after radical hysterectomy is not clearly understood. Plausible theories include direct sur­gical trauma, subsequent perivesical brosis, interruption of afferent sensory, parasympathetic and sympathetic autonomic motor nerves (Fig.33.4), and an impaired detrusor reex [15,
2426, 2835]. Overall, the likelihood of chronic
urinary tract dysfunction following a radical hys­terectomy may be related to preoperative func­tion, the degree of surgical neurological injury, and subsequent injury by bladder overdistention.
Better case selection, an improved under­standing of contributing surgical factors, appro­priate oncologic surgical modications, extended bladder rest in some cases, and highly selective use of adjuvant radiotherapy have all contributed

to a reduction in both the incidence and severity of this problem.
A smaller percentage of patients will develop stress or mixed urinary incontinence, especially when adjuvant radiotherapy has been adminis­tered [28, 32, 33, 43, 44]. Prevention and man­agement of these types of voiding dysfunction are less clear, but probably follow the same prin­ciples outlined for the denervation-related dys­function described.

Prevention

Prevention of postoperative bladder dysfunction begins with careful case selection. Large tumors require more extensive resection. These and deeply invasive tumors are more likely to have indications for postoperative adjuvant radiother­apy and are better managed primarily with chemoradiotherapy [45].
Modications of radical hysterectomy mark­edly reduce the incidence and severity of subse­quent bladder dysfunction (Fig.33.2) [1215, 26,
28, 4042, 4661]. The specic modications
include avoiding very lateral and caudal resection of the paravaginal, vesicovaginal and rectovaginal ligaments as well as limiting the extent of bladder

mobilization and vaginal resection [45]. These modications are consistent with an appropriate oncologic resection [6265]. A recent study has suggested that radicality involving less exten­sive vaginal resection (<3cm) will minimize the need for ongoing postoperative catheterization [66]. Therefore, larger vaginal resections should be limited as they can cause more damage to the pelvic oor. If resection leaves only the urethral vagina, the posterior urethro-vesical angle may be lost, which will predispose to lower urinary tract symptoms or LUTS (especially inconti­nence) [67]. Another recent study (prospective, randomized) concluded that simple hysterec­tomy is non-inferior to radical hysterectomy for women with low-risk cervical cancer (lesions of 2 cm with limited stromal invasion) [68].
Minimizing the use of postoperative adjuvant pelvic radiotherapy to appropriate indications is also an important factor in reducing the incidence of postoperative bladder dysfunction.
Postoperative bladder overdistention is a major contributing factor to short and especially long-term bladder dysfunction. The length of rec­ommended bladder rest following radical hyster­ectomy varies among studies and practices. Prior to discontinuation, an active voiding trial should be performed. Additionally, given the potential decrease in bladder sensation, the patient should be instructed to “void by the clock” in order to avoid bladder overdistention. Counseling on using Valsalva to aid in bladder emptying is also reasonable. When difculty with bladder empty­ing persists during the rst 6weeks after surgery, having the patient perform intermittent self­catheterization (ISC) is more likely to result in a degree of bladder recovery than further complete bladder rest.

Recognition

After an initial period of bladder rest, failure to pass an active voiding trial alerts the surgeon that more time for bladder recuperation is needed. If the patient is still not able to empty her bladder (<100cc post-void residual [PVR]) after 6weeks, then consideration should be given to instituting
ISC until the PVR is consistently <100 cc. Additional recovery of bladder function may occur over the next 6months, but beyond that, the problem is likely to be permanent [69].
An initially successful voiding trial may occa­sionally be followed, usually within days to weeks, by incomplete voiding. The problem accumulates until the patient presents with over­ow incontinence or inability to void, with a markedly overdistended bladder.

Management

For women with persistent inability to adequately void following radical hysterectomy, the main­stay of management is some form of catheteriza­tion. It is important to avoid both acute and chronic bladder overdistention, which will lead to infection and further decompensation of blad­der function. Pharmacologic agents may be tried but have been met with limited success. Catheter options are an indwelling Foley, ISC, or a supra­pubic tube.

Colorectal Dysfunction

Background

As with the bladder, extensive pelvic resection during radical hysterectomy may denervate the rectosigmoid colon. Unlike voiding dysfunction, this problem appears to be very uncommon [12,
56, 57]. Subsequent to surgery, the patient has a
segment of the rectosigmoid colon with poor peristaltic function.
Risk factors are unclear but likely include the extent of resection and associated pelvic nerve plexus denervation (as previously described) and preexisting chronic constipation and/or defeca­tory dysfunction. Whether specic aspects of the radical hysterectomy radicality, such as more extensive rectovaginal ligament resection, con­tribute to the development of this problem is not known. Survivorship studies suggest that the long-term effects of bowel dysfunction tend to be mild in isolated radical hysterectomy and are not
370
M. Homan et al.
signicantly impacted by the need for a radical procedure [70]. However, other studies compar­ing surgical radicality suggest that a more exten­sive procedure such as total mesorectal excision tends to have higher rates of dysfunction than radical hysterectomy alone [71].

Prevention

As with the prevention of bladder dysfunction, case selection that precludes the oncologic neces­sity of an extensive wide and deep resection of the paravaginal tissues would likely prevent most instances of signicant colorectal dysfunction following radical hysterectomy. Regardless, extensive resection of the uterosacral and recto­vaginal ligaments for cervical cancer does not have an oncologic basis [49, 6265].
During the weeks following a radical hyster­ectomy, there is a tendency toward bowel dys­function and constipation. It is good practice to maintain these patients on a bowel regimen that will help avoid severe constipation, which may be an additional contributing factor to the devel­opment of colorectal dysfunction.

Recognition

Women with signicant colorectal dysfunction following radical hysterectomy present in a man­ner similar to those who have undergone colorec­tal anastomosis, although the problem may involve a longer bowel segment and be more severe and persistent. There is a “functional obstruction”, with the ineffective passage of stool past this area resulting in chronic and severe constipation [72]. The problem persists despite conservative mea­sures. The combination of a colon transit study and defecography helps conrm the diagnosis.

Management

When women initially present postoperatively following radical hysterectomy, the mainstay of management is a good bowel regimen that
includes a bulking agent combined with adequate hydration and supplemented by a combination of laxatives and stool softeners. If studies conrm a defect in transition across the rectosigmoid colon, consideration is given to intensifying this regi­men. A small case series reported good results with segmental resection [73]. This should only be considered in severe, recalcitrant cases and after informed consent regarding both the poten­tial for a major complication (leak) and failure to improve the problem.
Vaginal Dehiscence andEvisceration
This topic is covered in Chap. 6. The incidence of vaginal cuff dehiscence with or without eviscera­tion does not appear to be signicantly different with radical versus simple hysterectomy.

Surgical Site Infection

Background

Surgical site infection (SSI) is the most common complication of gynecologic surgery and has been associated with mortality, prolonged hospi­talization, increased readmission rate, and long­term disability. SSIs are dened as “an infection related to an operative procedure that occurs at or near the surgical incision within 30 days” [74,
75]. With the implementation of routine preop-
erative antibiotics along with bundled surgical site infection preventions there have been decreased infection rates in gynecologic cancer surgery [74]. There are several risk factors that contribute to SSIs such as obesity, hyperglyce­mia, poor nutritional status, tobacco use, steroid use, and untreated infections. These are modi­able risk factors and should be evaluated and addressed prior to surgery, which may impact the outcome [75, 76].
Radical hysterectomy is classied as a clean­contaminated operation due to entry into the vagina. Cervical tumors may become infected, adding to the eld contamination. Following
33 Radical Hysterectomy
371
radical hysterectomy, surgical site infection may take the form of urinary tract infection (UTI), abdominal wound infection, pelvic cel­lulitis, or pelvic abscess. The pathogens that are attributed to SSIs are endogenous microbes of the skin, vagina, and gastrointestinal tract. When considering antimicrobial agents for gynecologic procedures, it is important to con­sider the three sites of infection: supercial inci­sional- involves the skin and subcutaneous layer, deep incisional- involves the deeper soft tissues of the incision such as muscle or fascia, and organ/space which involves any part of the anatomy other than the incised body layer [75,
77]. During a radical hysterectomy, the surgical
site is exposed to gram- positive, gram-negative, and anaerobic organisms. To effectively prevent SSIs, interventions are directed at broadly cov­ering these sites. Current studies and interven­tion strategies demonstrate a multi-modal approach has provided the greatest benet in decreasing complications.

Prevention

The most effective method of preventing SSIs is incorporating a bundled approach of administer­ing effective preoperative antibiotics and thor­ough preoperative surgical sterile measures. The components of this bundling method include patient factors such as optimization of modiable risk factors as briey mentioned above. Personal skin preparation prior to surgery includes avoid­ing hair removal (ie. shaving) and preoperative shower with 4% chlorhexidine gluconate. If hair removal is deemed necessary, this should be done in the operating room prior to surgery using hair clippers.
Generally, the routine use of intravenous cefazolin and metronidazole is recommended at least 1hour prior to skin incision and redosing of cefazolin at four hours or blood loss >1500mL, with increased dosing of cephalosporin for obese patients [74, 78, 79]. The addition of metronida­zole additionally addresses the common problem of bacterial vaginosis which occurs in a third of patients [74, 78, 80]. Preoperative treatment can
decrease the rate of vaginal cuff infections after hysterectomy.
Skin preparation prior to surgical incision should be with chlorhexidine gluconate and iso­propyl alcohol 70%. The vaginal tract should be prepped with either a povidone-iodine solution or chlorhexidine gluconate with 4% of isopropyl alcohol.
Wound infections are less common with active maintenance of intraoperative normothermia by pre-warming patients and avoiding a decrease in body temperature.
In a radical hysterectomy, there can be disrup­tion of autonomic innervation of the bladder which can cause voiding dysfunction. Prior to starting the procedure, a urethral catheter is placed into the bladder and historically the cath­eter is maintained into the postoperative period. Unfortunately, catheter-associated urinary tract infections (CAUTI) are common and carry seri­ous morbidity. CAUTIs are urinary tract infection symptoms with no other source of infection and with bacteriuria diagnosed within 48hours of a catheter left in situ. Preventative measures such as prophylactic antibiotics have not been shown to decrease CAUTIs [81, 82]. One of the most notable postoperative factors related to urinary tract infections is the duration of catheterization, and early catheter discontinuation should be con­sidered depending on the radicality of the surgery and the judgment of the surgeon.
Surgery should be meticulous, including avoidance of excess thermal damage to tissues and attention to hemostasis, while operating with pace. Abdominal wound closure should include subcutaneous layer approximation for obese women. Placing a vacuum device on the closed wound may be considered in high-risk cases, but the benet in terms of preventing wound infec­tion remains unclear.

Recognition

CAUTI is the most common hospital-acquired condition following gynecologic surgery, more so after a radical hysterectomy. While an indwell­ing urinary catheter is in place, symptoms of uri-
372
M. Homan et al.
nary tract infection (UTI) may not be apparent. Hematuria, although not uncommon secondary to mild trauma, may be a sign of infection cysti­tis. Following removal of the catheter, the patient may develop clinical UTI days to weeks later, which at times is chronic and difcult to eradi­cate. Fever, ank pain, costovertebral angle ten­derness, and leukocytosis are suggestive of pyelonephritis.
Following radical hysterectomy, clinically apparent pelvic cellulitis may develop days to weeks following surgery. The diagnosis is some­what subjective and made largely on clinical impression. Lower abdominal or pelvic discom­fort, tenderness on lower abdominal and espe­cially pelvic exam, fever, and leukocytosis may all be present. Vaginal discharge and/or a par­tially disrupted vaginal cuff may be present. Findings on imaging are nonspecic.
Abdominal wound infection (a common occur­rence in obese women) typically presents 1–2 weeks after surgery with tender, red, warm surrounding skin. Initially, there may be cellulitis with surrounding induration. This may progress to or initially present with uctuance or even puru­lent drainage. Imaging may be helpful in selected cases when the presence of a drainable abscess is unclear. Fever and leukocytosis may be present.
A pelvic abscess may develop in a small per­centage of patients, usually within 2–3 weeks postoperatively. The common presentation is lower abdominal or pelvic discomfort, fever, malaise, purulent vaginal drainage, leukocytosis, and an abscess found on imaging.

Management

Fevers in the rst 48hours are conservatively man­aged as this is most often related to cytokine release from tissue injury or atelectasis. The patient should be encouraged to ambulate, use incentive spirome­try, and respiratory toilet. After this time period if a fever persists, a thoughtful work-up should be completed for a postoperative patient.
When it is the clinical impression that an early abdominal wound infection has been identied
(cellulitis only), then management with antibiot­ics and warm compresses is initiated. If there is progression to or presentation with a wound abscess (or drainage with subcutaneous dehis­cence), then the wound should be opened. This can usually be done in the clinic or bedside set­ting but occasionally needs to be done in the operating room, especially when extensive debridement is required. After thorough drainage and washout of the wound, care may consist of moist-to-dry dressings or a wound vacuum sys­tem. Some patients are candidates for subsequent secondary closure.
UTI that is clinically conned to cystitis is treated, ideally, with a culture-directed antibiotic in addition to a urinary anesthetic. Pyelonephritis with signs of systemic infection requires initial hospitalization for supportive care and intrave­nous antibiotics. Ureteral obstruction should be ruled out in such cases.
Clinically diagnosed pelvic cellulitis is treated with broad-spectrum antibiotics. Hospitalization may not be necessary.
Pelvic abscess that develops following radical hysterectomy requires antibiotics and drainage. The route of drainage is individualized and gen­erally can be accomplished percutaneously by interventional radiology or transvaginally.

Sexual Dysfunction

Background

A standard part of a radical hysterectomy is the removal of a portion of the upper vagina. The length of the vagina removed depends on the rad­icality of the operation, varying from approxi­mately 2–4cm. The loss of this portion is rarely of clinical signicance in terms of sexual func­tion, likely due to the distensibility of the vagina and its ability to stretch. Associated factors that may impair vaginal health and function include concomitant removal of the ovaries in premeno­pausal women, adjuvant radiation therapy (more so if this includes vaginal brachytherapy), and the radicality of the operation [38, 70, 71].
