Decreasing post hysterectomy surgical site infections with the implementation of a hysterectomy-specific bundle.

BACKGROUND: Surgical site infections (SSI) are a common complication of hysterectomy. Surgical bundles have been shown to reduce SSIs. Here we describe a bundle that was used to combat an abnormal rise in SSI events that resulted in a greater than 75% reduction at our institution. METHODS: A hysterectomy-specific bundle was developed based on the prior success of SSI prevention bundles. Development involved longitudinal education and training to ensure accuracy and compliance. All inpatient abdominal, laparoscopic, and vaginal hysterectomies performed at a tertiary referral center were included. The preintervention, intervention, and postintervention periods were each one year in length. SSI rates were peer-reviewed monthly and overall trends were tracked, including compliance with bundle guidelines. RESULTS: Preintervention, an abnormal rise in SSI was identified at 3.76%. During the intervention, 309 inpatient hysterectomies were completed. In this period, 6 posthysterectomy SSI events occurred (3.76% vs 1.94%, P = .21). Four SSIs followed laparotomy and 2 followed laparoscopy. Compliance during the intervention period ranged from 79% to 89% with a mean of 85%. In the postintervention period, there were 6 SSI following 689 hysterectomies (3.76% vs 0.87%, P = .004). The majority of SSI occurred after abdominal hysterectomy. CONCLUSIONS: Implementation of a hysterectomy-specific surgical bundle allowed for a significant reduction in post hysterectomy SSI during a yearlong intervention period and a sustained, further reduction in the postintervention period.

Contained specimen morcellation during robotics-assisted laparoscopic supracervical hysterectomy for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: Robotics-assisted laparoscopic supracervical hysterectomy (RALSH) with concomitant apical robotics-assisted POP repair provides advantages of minimally invasive procedures; however specimen removal without intraperitoneal spillage of potential pathology remains challenging. The primary aim of our study is to determine the factors affecting contained manual morcellation (CMM) of specimens during RALSH for POP surgery. The secondary aim of the study is to report complications associated with CMM and on specimen pathology. METHODS: A total of 67 sequential patients underwent RALSH with concomitant robotics-assisted sacrocolpopexy or uterosacral vaginal suspension. Factors analyzed to affect CMM were specimen weight, length of skin and fascia incisions, patient age, body mass index (BMI), and estimated blood loss (EBL). RESULTS: Median CMM time was 11 min (1 to 46) and specimen weight 62 g (19 to 711). Median patient age was 56 years (36 to 83), and patient BMI was 28 (18 to 44). Median EBL was 50 ml (10 to 150). Median skin and fascial incision lengths were 3 cm (1.5 to 7), and 3.5 cm (1.5 to 8). CMM time was significantly dependent on specimen weight (p < 0.0001) and length of rectus fascia incision (p < 0.0126). There was no gross tissue spillage or bag ruptures. Uterine pathology revealed normal tissue (26%), leiomyoma (47%), adenomyosis (49%), and endometriosis (14%). 4.5% of specimens had evidence of microscopic neoplasm, and 5 years after surgery patients were cancer free. CONCLUSION: Contained manual extraction of the uterus and/or adnexae at the time of RALSH for POP surgery is a viable, safe, and efficient method of specimen removal.

Pessaries and rectovaginal fistulae: consequences of delayed clinical follow-up in the Covid-19 pandemic.

INTRODUCTION AND HYPOTHESIS: While 2017 guidelines from The American College of Obstetricians & Gynecologists called for pessary replacement every 3 to 4 months, a recent study in Obstetrics and Gynecology suggested that uninterrupted pessary use up to 6 months is not an independent risk factor for development of pessary-related complications. METHODS: Our recent experience throughout the Covid-19 pandemic highlights the potential ramifications of delayed clinical follow-up. RESULTS: During the Covid-19 pandemic, 3 of our patients developed rectovaginal fistulae secondary to Gellhorn pessary erosion in the context of delayed clinical follow-up. Our patients had previously attended routine appointments every 3 months without complications until missed appointments secondary to the pandemic led to fistulae formation. CONCLUSION: We believe that delayed clinical follow-up of pessary management beyond 3 months due to the Covid-19 pandemic may lead to fistula complications in elderly women with Gellhorn pessaries.

Robotic Repair of Complicated Vesico-[utero]/Cervicovaginal Fistula after Cesarean Section.

STUDY OBJECTIVE: To demonstrate intra- and postoperative steps in a successful management of a complicated vesico-[utero]/cervicovaginal fistula. DESIGN: Stepwise demonstration of the technique with narrated video footage. SETTING: A urogenital fistula in developed countries mostly occurs after gynecologic surgeries but rarely from obstetric complications. The main treatment of a urogenital fistula is either transvaginal or transabdominal surgical repair. We present a case of a 36-year-old woman, gravida 3 para 3-0-0-3, who developed a complicated large vesico-[utero]/cervicovaginal fistula after an emergent repeat cesarean section. Robotic repair was performed 2 months after the injury using the modified O'Connor method. Blood loss was minimal, and the patient was discharged from the hospital 1 day postoperatively. Follow-up showed complete healing of the fistula with no urine leakage, frequency of urination, or dyspareunia. The patient resumed normal bladder function and menstrual period up to 4 months after the repair procedure. INTERVENTIONS: The basic surgical principle of urogenital fistula repair is demonstrated: (1) development of vesicovaginal spaces by dissection of the bladder from the uterus and the vagina, (2) meticulous hemostasis, (3) adequate freshened of the fistula edges, (4) tension-free and watertight closure of the bladder. We also demonstrate some other techniques that have developed though our own practice: (1) facilitating bladder distention by temporarily blocking the fistula, (2) placement of a ureteral catheter to protect the ureters, (3) interposition with omental flap, (4) single layer through and through closure of a cystotomy with 2-0 V-Loc suture (Covidien, Irvington, NJ). CONCLUSION: Complicated urogenital fistulas may be repaired successfully using minimally invasive surgery using robotic assistance, enabling less blood loss, faster recovery, shorter hospital stay, and fewer complications, etc.

Improved Understanding of Female Pelvic Medicine and Reconstructive Surgery Concepts Through Targeted Case-Based Educational Intervention: A Pilot Study.

OBJECTIVES: Given the complex anatomy and pathophysiology of urogynecologic disorders, obstetrics and gynecology residents can have difficulty learning the subject's principles. There are no standardized resources for educators in this subspecialty. We hypothesized that our case-based educational intervention was associated with enhanced knowledge and greater resident satisfaction versus traditional urogynecology lectures. METHODS: This is a prospective study involving 19 obstetrics and gynecology residents at a single institution. Residents participated in three 1-hour case-based lectures, which included prelecture and postlecture topic knowledge assessments. Nonparametric Wilcoxon signed-rank tests were used to compare the before and after responses. Resident satisfaction was assessed using a 5-point Likert scale questionnaire. RESULTS: The median scores for the pretraining and posttraining assessments of resident urogynecology subject knowledge were 8 (5-10) and 10 (8-10), respectively. A stratified analysis was performed based on postgraduate year (PGY) and median prelectures and postlectures scores showed statistically significance (P < 0.001). Analysis of the PGY subgroups demonstrated statistical significance in PGY1 (P = 0.004), PGY2 (P = 0.008), and PGY3 (P = 0.03). However, the PGY4 subgroup (P = 0.06) did not reach statistical significance.All residents regardless of PGY level either agreed or strongly agreed that the case-based educational intervention enhanced resident knowledge, engagement, and clarity of the relevant teaching points and decreased resident stress about urogynecology topics. CONCLUSIONS: The case-based educational intervention significantly improved resident knowledge in urogynecology and enhanced resident satisfaction with this teaching method versus traditional lectures.

Outcomes of stress urinary incontinence in women undergoing TOT versus Burch colposuspension with abdominal sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: To compare postoperative rates of stress urinary incontinence (SUI) in patients with pelvic organ prolapse and SUI undergoing abdominal sacrocolpopexy (ASC) with Burch colposuspension or a transobturator tape (TOT) sling. METHODS: In this retrospective cohort study, medical records of 117 patients who underwent ASC with Burch (n = 60) or TOT (n = 57) between 2008 and 2010 at NYU Winthrop Hospital were assessed. Preoperative evaluation included history, physical examination, cough stress test (CST), and multichannel urodynamic studies (MUDS). Primary outcomes were postoperative continence at follow-up up to 12 weeks. Patients considered incontinent reported symptoms of SUI and had a positive CST or MUDS. Secondary outcomes included intra- and postoperative complications. Associations were analyzed by Fisher's exact, McNemar's and Wilcoxon-Mann-Whitney tests. RESULTS: The groups were similar regarding age, BMI, parity, Valsalva leak point pressure (VLPP), and prior abdominal surgery (p = 0.07-0.76). They differed regarding preoperative SUI diagnosed by self-reported symptoms, CST, or MUDS (TOT 89.5-94.7%, Burch 60.7-76.3%, p < 0.0001-0.007). The TOT group had lower rates of postoperative SUI (TOT 12.5%, Burch 30%, OR = 0.15, 95% CI 0.04, 0.62). Relative risk reduction (RRR) in postoperative SUI for the TOT group compared with the Burch group was 79%-86%. There were no differences concerning intra- and postoperative complications. The Burch group had a higher rate of reoperation for persistent/recurrent SUI (Burch 25%, TOT 12% p = 0.078). CONCLUSIONS: The TOT group experienced a greater reduction in postoperative incontinence, and the Burch group underwent more repeat surgeries. The TOT sling may be superior in patients undergoing concomitant ASC.

Update on Urinary Tract Markers in Interstitial Cystitis/Bladder Pain Syndrome.

Interstitial cystitis (IC)/painful bladder syndrome/bladder pain syndrome (BPS) is a chronic hypersensory condition of unknown etiology. Moreover, the optimal modality for diagnosing IC remains disputed. Several urinary markers have been investigated that may have potential utility in the diagnosis or confirmation of IC/BPS. Thus, inflammatory mediators, proteoglycans, urinary hexosamines, proliferative factors, nitric oxide (NO), BK polyomavirus family, and urothelial proinflammatory gene analysis have been found to correlate with varying degrees with the clinical diagnosis or cystoscopic findings in patients with IC/BPS. The most promising urinary biomarker for IC/BPS is antiproliferative factor, a sialoglycopeptide that has demonstrated inhibitory effects on urothelial cell proliferation and a high sensitivity and specificity for IC/BPS symptoms and clinical findings. In this article, we review the urinary markers, possible future therapies for IC/BPS, and the clinical relevance and controversies regarding the diagnosis of IC/BPS.

Postoperative adhesion formation in a rabbit model: monopolar electrosurgery versus ultrasonic scalpel.

BACKGROUND AND OBJECTIVES: To determine if surgery using ultrasonic energy for dissection results in less adhesion formation than monopolar electrosurgical energy in the late (8 weeks) postoperative period. METHODS: Injuries were induced in rabbits by using ultrasonic energy on one uterine horn and the adjacent pelvic sidewall and using monopolar energy on the opposite side. Eight weeks postoperatively, the rabbits underwent autopsy and clinical and pathologic scoring of adhesions was performed by blinded investigators. RESULTS: There was no significant difference in clinical adhesion scores between the two modalities. The mean clinical score for monopolar cautery was 1.00 versus 0.88 for the Harmonic device (Ethicon Endo-Surgery, Cincinnati, Ohio) (P = .71). Furthermore, there was no significant difference found in the pathologic adhesion scores between the ultrasonic scalpel and monopolar energy. The mean pathologic score for monopolar electrosurgery was 4.35 versus 3.65 for the Harmonic scalpel (P = .30). CONCLUSION: Neither monopolar electrosurgery nor ultrasonic dissection is superior in the prevention of adhesion formation in the late postoperative period.

Management of infected urethral diverticulum with urethral dilation.

BACKGROUND: Urethral diverticula are rare but underdiagnosed entities that may cause a variety of urinary and pelvic symptoms in women. Management can be very challenging, especially in cases of chronic infection. CASE: A 69-year-old gravida 4, para 2 woman with a history of type 2 diabetes and hypothyroidism presented with long history of a painful midline 3-cm suburethral cystic mass, recurrent urinary tract infections, dysuria, dyspareunia, and incomplete voiding. The diagnosis was consistent with an infected urethral diverticulum unresponsive to multiple courses of oral antibiotics. Given the patient's comorbidities and the persistence of infection of the diverticulum, conservative treatment with urethral dilation was performed before surgical treatment. Urethral dilation successfully alleviated the patient's symptoms; the surgical treatment was not ultimately required, and the patient continues to be completely asymptomatic well over 17 months later. CONCLUSIONS: We present a unique case of infected urethral diverticulum, which was conservatively treated with dilatation and resulted in resolution of all symptoms, and there is no need for further surgical management.

Delayed small bowel obstruction after robotic-assisted sacrocolpopexy.

We report 2 unusual cases of partial bowel obstruction resulting from adherence to a barbed suture presenting 3 to 4 weeks after robotic-assisted sacrocolpopexy for uterovaginal prolapse. Both patients underwent an uncomplicated robotic-assisted supracervical hysterectomy and sacrocolpopexy. Immediate postoperative recovery was uncomplicated. Three to four weeks after surgery, both patients presented with symptoms of nausea, vomiting, and abdominal pain and were found to have small bowel obstructions requiring a return to the operating room. Upon surgical exploration, a loop of small bowel was found to be adhered to a segment of the barbed suture at the sacral promontory, which had been used to close the peritoneum over the mesh. Subsequent to release, both patients had an uneventful recovery.

Rare case of neglected pessary presenting with concealed vaginal hemorrhage.

BACKGROUND: Vaginal pessaries are commonly used for management of pelvic organ prolapse. Severe complications can occur in neglected cases. CASE: A 91-year old woman with significant comorbidities presented with large concealed vaginal bleeding and history of vaginal pessary placement 14 years before. On examination, an impacted Gellhorn pessary in the vagina was noted with some spotting. Serum blood tests revealed severe anemia and renal insufficiency. An abdominal and pelvic computed tomographic scan confirmed a Gellhorn pessary and a large vaginal accumulation of blood superior to impaction. The pessary was surgically removed vaginally under anesthesia. Recovery was uneventful, and the patient was discharged 1 week later. CONCLUSION: Our case underlines the need of follow-up and compliance after pessary placement for early detection of complications.

Lung collapse secondary to mucus plug in a gynecologic patient after reconstructive pelvic surgery.

This is the case of a 45-year-old woman with a history of asthma and smoking who developed complete left lung and right upper lobe collapse secondary to mucus plugs that developed immediately postoperatively after an uncomplicated reconstructive pelvic surgery. This rare intraoperative complication was successfully treated in the recovery room with bedside fiber-optic bronchoscopy. This resulted in complete resolution of her pulmonary findings within 24 hours of bronchoscopy.

Intraoperative Crede maneuver for tape adjustment during transobturator sling placement: does it improve continence?

OBJECTIVE: This study evaluated the efficacy of intraoperative extrinsic manual compression on the bladder, or Crede maneuver (CM) for tape adjustment during transobturator tape (TOT) sling procedure versus the traditional method where tension-free tape is adjusted the same for all patients. METHODS: All patients undergoing TOT sling procedure for stress urinary incontinence (SUI) between May 2008 and June 2011 by the first author were assessed. Tape adjustment was either performed in a traditional manner, leaving a tonsil clamp-size space between the sling and posterior urethra, or by using CM after filling the bladder to 300 ml capacity. Patients were considered cured at postoperative visits if they had no SUI symptoms and negative Cough Stress Test (CST) result, improved if they had some SUI symptoms and negative CST result, and failed if symptomatic and had positive CST result. The Fisher exact test and the Wilcoxon rank sum test were used to evaluate the baseline differences between the 2 groups, along with multiple logistic regression to evaluate independent predictors of cure. RESULTS: The continence rate was 77.67% in the traditional group (87/112) and 79.65% (137/172) in the CM group (P = 0.76). Older patients and smokers were less likely to be continent (odds ratio, 0.95; P = 0.015; and odds ratio, 0.22; P = 0.003, respectively). Five (4.5%) of the 112 patients in the traditional group and 12 (6.9%) of the 172 patients in the CM group had adverse outcomes including transient urinary retention, mesh erosion, or dysuria (P = 0.45). CONCLUSION: Using CM for intraoperative tape adjustment does not improve continence rates compared to the traditional method of TOT sling placement.

Complete labial fusion with vaginal constriction band presenting as incomplete voiding.

BACKGROUND: Labial adhesions are most commonly described in prepubertal girls. Only a few cases have been reported in postmenopausal women presenting with incomplete voiding. CASE: This report describes a case of a 51-year-old postmenopausal woman who presented with incomplete voiding and urinary incontinence. On examination, she had complete labial fusion and intraoperative findings of distal vaginal stenosis due to a constriction band. The patient was surgically treated with lysis of the labial fusion, posterior vaginal advancement flap with complete resolution of her urinary symptoms. CONCLUSION: In this report, we present a case of a postmenopausal patient with complete labial fusion, distal vaginal stenosis, and incomplete voiding who underwent successful surgical management with good anatomical results and complete resolution of urinary symptoms.

Endoscopic balloon dilation in the management of ureteral stricture after urogynecologic surgery: a case report.

BACKGROUND: Ureteral injuries are known complications of urogynecologic surgery. Until now, ureteral reimplantation with laparotomy has been used in cases in which ureteral stenting of distal obstruction was unsuccessful. CASE: We report a case of a 74-year-old woman with a recognized right ureteral injury after vaginal reconstructive surgery that failed ureteral stenting to relieve the obstruction and who presented with ureteral stricture and mild hydronephrosis 6 weeks postoperatively. Ureteroscopy with endoscopic balloon dilation reduced the stricture successfully. The patient remains asymptomatic, with normal renal sonogram, 6 months after the procedure. CONCLUSION: Endoscopic balloon dilation is an effective technique that can be used for the management of ureteral strictures after urogynecologic surgery and avoids further surgical intervention.

Strategies to minimize adhesion formation after surgery.

OBJECTIVES: To compare the potential for postoperative laparoscopic adhesion formation utilizing either monopolar cautery or ultrasonic energy and to determine whether there is added benefit with the addition of a suspension of hyaluronate/carboxymethylcellulose in saline versus saline alone. METHODS: Injuries were induced in rabbits by using monopolar cautery on 1 uterine horn and adjacent sidewall and ultrasonic energy on the opposite. Hyaluronate/carboxymethylcellulose or saline was added to every other animal. Autopsies were performed after 3 weeks. Clinical and pathologic scoring of adhesions was performed by blinded investigators. RESULTS: A very significant difference occurred in pathologic adhesion scores favoring the ultrasonic scalpel when the animals were treated with saline. However, a borderline significant difference was found in pathologic scores favoring the ultrasonic scalpel compared to the monopolar cautery. There was no significant difference in clinical adhesion scores between the 2 modalities. No significant difference in either score was found with the addition of hyaluronate/carboxymethylcellulose or saline with either instrument. CONCLUSION: No benefit was found for adhesion prevention with hyaluronate/carboxymethylcellulose. Although no reduction was achieved in clinical adhesions, the ultrasonic scalpel resulted in fewer histologic signs of tissue inflammation in the early postoperative period, suggesting that further clinical adhesions might develop over time with cautery.

A case of a large rectovaginal mass presenting as posterior vaginal wall prolapse.

A 66-year-old female presented with symptoms suggestive of pelvic organ prolapse, history of fibroid uterus, and rectal pressure. Pelvic examination revealed a large pelvic mass filling the posterior cul-de-sac, occupying the rectovaginal septum, and compressing the rectum. There was a stage II pelvic organ prolapse of the posterior vaginal wall with distal vaginal wall extending to the hymen during valsalva. A CT scan confirmed the large pelvic mass distinct from the uterus measuring 9.4 × 9.8 × 6.2 cm. Colorectal workup revealed adenocarcinoma of colon on screening colonoscopy with biopsies. Patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy, colon resection, and abdominal resection of the pelvic mass in the rectovaginal septum and inferior to the uterus. The patient did not require any concomitant pelvic reconstruction and the posterior vaginal wall prolapse resolved after resecting the pelvic mass.

Enlarging perineal endometrioma developing after colpoperineorrhaphy.

Although endometriosis is not infrequent, the occurrence of perineal endometriomata is relatively rare and is generally attributed to seeding of endometrial cells to the perineal body during obstetrical trauma. A 45-year-old female with a history of a colpoperineorrhaphy during menses and a remote history of obstetric perineal trauma presented with an enlarging perineal mass. Excision of the mass led to a clinical and histopathologic diagnosis of perineal endometriosis. Elective surgery disrupting the vaginoperineal epithelium performed during menses may facilitate the seeding of endometrial cells to the perineal body and formation of perineal endometriomata.

Variant iliocaval confluence discovered during sacrocolpopexy.

BACKGROUND: Laceration of the iliac veins and their branches is a feared complication in abdominal sacral colpopexy. Hemorrhages can be extensive and difficult to control. CASE: We report a case of a patient who, while undergoing abdominal sacral colpopexy, was found to have confluence of the iliac veins at the level of the second sacral vertebra instead of the expected fourth lumbar to first sacral vertebral bodies. The intraoperative course had to be revised because of the increased risk of bleeding. The patient tolerated the procedure well and without any complications. CONCLUSION: With pelvic reconstructive surgery becoming more commonplace, knowledge of possible anomalous vessels is important because modification of planned surgical approach may be necessary to avoid short-term and long-term complications.

Late-onset allergic reaction to povidone-iodine resulting in vulvar edema and urinary retention.

BACKGROUND: Povidone-iodine, a surgical antiseptic, is associated with adverse side effects ranging from minor skin irritation to anaphylaxis, with symptoms occurring within minutes and up to 8 hours after contact. CASE: We report a case of a patient, with no history of allergy to povidone-iodine, who developed an allergic reaction 24 hours after intraoperative exposure to povidone-iodine, presenting with acute urinary retention secondary to extensive vulvar edema, which resolved after administration of antihistamines. CONCLUSION: Allergic reactions to povidone-iodine can be late in onset and, in vaginal surgeries, may present with atypical symptoms such as acute urinary retention secondary to vulvar edema. Prompt diagnosis and effective treatment requires strong clinical suspicion in patients presenting postoperatively with a known history of exposure.
