Effect of remote cesarean delivery on complications during hysterectomy: a cohort study

The impact of a previous cesarean section on the risk of perioperative and postoperative complications during vaginal hysterectomy

OBJECTIVE

To investigate whether a previous cesarean section increases the risk of perioperative and postoperative complications during vaginal hysterectomy.

METHODS

A retrospective cohort study of women who had undergone a vaginal hysterectomy for benign indications between 2014 and 2019 was conducted, comparing patients with or without a previous cesarean section. Perioperative and postoperative complications during vaginal hysterectomy were assessed according to the Clavien-Dindo classification system within 30 days of surgery. Duration of surgery, estimated blood loss, and postoperative hospitalization days were also recorded. A two-sided P value of less than 0.05 was considered significant.

RESULTS

A total of 185 women were included, 25 (13.5%) patients had undergone a previous cesarean section (study group) and 160 (86.5%) had no history of cesarean section (comparison group). We found no significant differences in demographic and clinical characteristics as well as postoperative complications and interventions, duration of surgery, estimated blood loss, and postoperative hospitalization days (P > 0.05). However, patients who underwent two or more cesarean sections had a significantly (P = 0.01) higher rate and grade of complications during vaginal hysterectomy, compared with women with only one previous cesarean section. All women who underwent two or more cesarean sections had mild complications during vaginal hysterectomy (40% grade I and 60% grade II, P = 0.01).

CONCLUSION

Vaginal hysterectomy is a safe procedure with few severe complications, regardless of a previous cesarean section. More than one previous cesarean section may increase the risk of minor complications during a vaginal hysterectomy. Patients who underwent a previous cesarean section could be reassured that they do not face an increased risk of complications during a vaginal hysterectomy.

Cesarean scar disorder: Management and repair

Cesarean scar disorder (CSD) is an entity recently defined as uterine niche with at least one primary or 2 secondary symptoms. CSDs can be visualized by hysterosalpingography, transvaginal sonography, saline infusion sonohysterography, hysteroscopy, and magnetic resonance imaging, but diagnosis should be performed by exams able to measure the residual myometrial thickness (RMT). Although there is a limited number of studies evaluating fertility and reproductive outcomes after different types of surgery, the following consideration should be kept in mind. Asymptomatic women should not be operated with the hope of improving obstetrical outcomes. It is reasonable to consider hormone therapy for CSDs as a symptomatic treatment in women who no longer wish to conceive and have no contraindications. In case of failure of or contraindications to medical treatment, surgery should be offered according to the severity of symptoms, including infertility, the desire or otherwise to preserve the uterus, the size of the CSD, and RMT measurement. Hysteroscopy is considered to be more of a resection than a repair, so women who desire pregnancy should be excluded from this technique in case of RMT <3 mm. In this instance, repair is essential and can only be achieved by a laparoscopic or vaginal approach. The benefit of laparoscopic approach seems to persist after subsequent CS. Women with CSDs need to be given complete information, including available literature, before any treatment decision is made.

Lateral closure of the uterine artery prior to laparoscopic hysterectomy: a systematic review

An alternative surgical technique with closure of the uterine artery at its origin, known as lateral approach prior to TLH, has been proposed and it may offer important benefits to both patients and surgeons. Our objectives were to review the current literature regarding surgical outcomes between lateral and conventional approach in relation to TLH. We followed the 'PRISMA' guidelines and conducted a systematic review, which involved searching PubMed and Embase databases for RCTs evaluating the topic. We identified four RCTs including 585 patients. Three of the four studies reported a significant lower bleeding during TLH with prior lateral approach. Operative time was also shorter in the lateral approach group compared to the conventional approach group in three studies.Our review provides evidence that lateral occlusion of the uterine arteries prior to total laparoscopic hysterectomy may be beneficial due to less blood loss and shorter perioperative time without compromising patient safety.

Risk Factors for Urologic Injury in Women Undergoing Hysterectomy for Benign Indication

OBJECTIVE

To investigate risk factors associated with urologic injury in women undergoing hysterectomy for benign indication.

METHODS

A retrospective cohort study for the period of 2011-2018 was conducted using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Women without urologic injury were compared with women with injury. A pre-specified multivariable logistic regression model, controlling for key patient demographic factors and intraoperative variables, was used to assess for surgical factors associated with urologic injury.

RESULTS

Among 262 117 women who underwent hysterectomy for benign indication, 1539 (0.6%) sustained urologic injury. On average, patients with urologic injury were younger, had lower body mass index (BMI), and more frequently underwent a transabdominal surgical approach. Patients who underwent total hysterectomy had increased odds of urologic injury than those who underwent subtotal hysterectomy (adjusted OR [aOR] 1.49; 95% confidence interval [CI] 1.21-1.84). Patients with class III obesity had lower odds of injury than patients with normal BMI (aOR 0.64; 95% CI 0.51-0.80). For risk of urologic injury, an interaction was observed between surgical approach and surgical indication. Abdominal compared with laparoscopic approach was associated with urologic injury for women with endometriosis (aOR 2.98; 95% CI 1.99-4.47), pelvic pain (aOR 3.51; 95% CI 1.74-7.08), menstrual disorders (aOR 4.33; 95% CI 1.68-11.1), and fibroids (aOR 2.28; 95% CI 1.72-3.03). Vaginal compared with laparoscopic approach was associated with increased odds of injury for women with menstrual disorders (aOR 7.62; 95% CI 1.37-42.5).

CONCLUSION

While the risk of urologic injury during hysterectomy for benign indication is low, the risk is dependent on patient disease factors and surgical approach.

Therapeutic approach of uterine leiomyoma; choosing the most appropriate surgical option

The most common benign pelvic tumor in young women is uterine leiomyoma. It is often asymptomatic, but can cause symptoms such as pelvic-abdominal pain, vaginal bleeding, urinary and intestinal transit disorders. If there is a suspicion of malignancy, it is necessary to perform fractional uterine curettage to establish the histopathological diagnosis.The surgical treatment of uterine leiomyoma includes several procedures: myomectomy, subtotal or total hysterectomy. The procedure will be chosen depending on the patient's particularities: BMI, uterine size, leiomyoma location, surgical history or other associated pathologies.Laparoscopic hysterectomy has a 45-minute shorter duration of intervention than vaginal hysterectomy, and the conversion rate to the open procedure is lower.Laparoscopically treated cases have fewer postoperative complications compared to other surgical procedures and have a shorter hospitalization and recovery time.The recurrence rate of uterine leiomyoma is similar for both laparoscopic and open abdominal approach, and the frequency of long-term complications such as adhesion syndrome or pelvic pain is higher after the latter.

Risk-prediction Model for Patients Undergoing Laparoscopic Hysterectomy

STUDY OBJECTIVE

Develop a model for predicting adverse outcomes at the time of laparoscopic hysterectomy (LH) for benign indications.

DESIGN

Retrospective cohort study.

SETTING

Large academic center.

PATIENTS

All patients undergoing LH for benign indications at our institution between 2009 and 2017.

INTERVENTIONS

LH (including robot-assisted and laparoscopically assisted vaginal hysterectomy) was performed per standard technique. Data about the patient, surgeon, perioperative adverse outcomes (intraoperative complications, readmission, reoperation, operative time >4 hours, and postoperative medical complications or length of stay >2 days), and uterine weight were collected retrospectively. Pathologic uterine weight was used as a surrogate for predicted preoperative uterine weight. The sample was randomly split, using a random sequence generator, into 2 cohorts, one for deriving the model and the other to validate the model.

MEASUREMENTS AND MAIN RESULTS

A total of 3441 patients were included. The rate of composite adverse outcomes was 14.1%. The final logistic regression risk-prediction model identified 6 variables predictive of an adverse outcome at the time of LH: race, history of laparotomy, history of laparoscopy, predicted preoperative uterine weight, body mass index, and surgeon annual case volume. Specifically included were race (97% increased odds of an adverse outcome for black women [95% confidence interval (CI), 34%-110%] and 34% increased odds of an adverse outcome for women of other races [95% CI, -11% to 104%] when compared with white women), history of laparotomy (69% increased odds of an adverse outcome [95% CI, 26%-128%]), history of laparoscopy (65% increased odds of an adverse outcome [95% CI, 21%-124%]), and predicted preoperative uterine weight (2.9% increased odds of an adverse outcome for each 100-g increase in predicted weight [95% CI, 2%-4%]). Body mass index and surgeon annual case volume also had a statistically significant nonlinear relationship with the risk of an adverse outcome. The c-statistic values for the derivation and validation cohorts were 0.74 and 0.72, respectively. The model is best calibrated for patients at lower risk (<20%).

CONCLUSION

The LH risk-prediction model is a potentially powerful tool for predicting adverse outcomes in patients planning hysterectomy.

Urinary System Iatrogenic Injuries: Problem Review

INTRODUCTION

From May to December 2019, a literature review of the urinary system iatrogenic injury problem was performed. The most cited, representative articles in PubMed, Scopus, and WoS databases dedicated to this problem were selected. Urinary system iatrogenic injuries include ureter, bladder, urethra, and kidney traumas. It is widely thought that the main causes of such injuries are urological, obstetric, gynecological, and surgical operations on the retroperitoneal space, pelvis, or perineum.

METHODS

The purpose of the study is to describe all aspects of the iatrogenic injure problem, under the established scheme and for each of the most damaged organs: the urethra, bladder, kidney, and ureter. The treatment of confirmed iatrogenic injuries largely depends on the period of its detection. Modern medical procedures provide conservative or minimally invasive treatment. An untimely diagnosis worsens the treatment prognosis. "Overlooked" urinary system trauma is a serious threat to society and a particular patient. Thus, incorrect or traumatic catheterization can lead to infection (RR 95%) and urethral stricture (RR ≥11-36%), and percutaneous puncture nephrostomy can cause the risk of functional renal parenchyma loss (median 5%), urinary congestion (7%), or sepsis (0.6-1.5%).

RESULTS

Lost gain, profits, long-term and expensive, possibly multistage treatment, stress and depression, and the risks of suicide put a heavy financial, moral, and ethical burden on a person and society. Also, iatrogenic injury might have legal consequences.

DISCUSSION/CONCLUSION

Thus, the significant problem of urinary tract iatrogenic injuries is still difficult to solve. There is a need to implement mandatory examining algorithms for patients at risk, as well as the multidisciplinary principle for all pelvic surgery.

Iatrogenic ureteral injury during retroperitoneal laparoscopy for large renal cysts: What we learned and a review of the literature

PURPOSE

To avoid Iatrogenic ureteral injury during retroperitoneal laparoscopy for large renal cyst (diameter > 70 mm), we present two cases of iatrogenic ureteral injury and discuss their clinical courses and final outcomes.

PATIENTS AND METHODS

Two male patients (47 years old and 74 years old) with large left simple renal cysts underwent a retroperitoneal laparoscopic operation to treat the cysts. In the first patient, the left proximal ureter was partially transected (Grade 3) during the operation. The injury was identified intraoperatively. The transection was managed with a primary ureteroureterostomy (end to end) along with a double J ureteral stent. In the second patient, the left proximalureter was partially transected (Grade 4). However, the injury was unrecognized postoperatively for two days. After recognition of the complication, the injury was managed with an early primary ureteroureterostomy, which followed a failed attempt to place ureteral stent endoscopically.

RESULTS

In the first patient, a postoperative urinary leakage developed and lasted for 13 days. During long term follow-up of the first patient after the urine leak resolved, there were no reports of pain in the lumbar region or other discomfort. No recurrence of the renal cyst occurred, which was confirmed with an ultrasound at one year postoperatively. In the second patient a ureteral fistula and severe perirenal infection occurred and lasted for 86 days. The patient ultimately underwent a left nephrectomy after conservative management for this surgical complication failed. This patient developed a chronic wound infection that lasted for 3.14 months following the nephrectomy. During follow-up post nephrectomy, the patient developed stage 3B moderate chronic kidney disease (CKD) (GFR = 30 -44 ml/min).

CONCLUSIONS

For single large (diameter > 70 mm) renal cysts located at the lower pole of the kidney, it is recommended to not completely dissect out and mobilize the entire renal cyst for cyst decortication in order to avoid injuring the ureter. Iatrogenic ureteral injury increases the risk of readmission and serious life-threatening complications. The immediate diagnosis and proper management ureteric injury can reduce complications and long term sequalae.

Cesarean scar defects: management of an iatrogenic pathology whose prevalence has dramatically increased

Around 20% of pregnant women undergo cesarean section (CS), and in most regions of the world CS rates continue to grow. There is still no clear definition of what is considered a normal physiologic aspect of a CS scar and what is abnormal. Cesarean scar defects (CSDs) should be suspected in women presenting with spotting, dysmenorrhea, pelvic pain, or infertility and a history of CS. CSDs can be visualized with the use of hysterosalpingography, transvaginal sonography, saline infusion sonohysterography, hysteroscopy, and magnetic resonance imaging. It is reasonable to consider hormone therapy for CSDs as a symptomatic treatment in women who no longer wish to conceive and have no contraindications. In case of failure of or contraindications to medical treatment, surgery should be contemplated according to the severity of symptoms, including infertility, the desire or otherwise to preserve the uterus, the size of the CSD, and residual myometrium thickness (RMT) measurement. Hysteroscopy is considered to be more of a resection than a repair, so women who desire pregnancy should be excluded from this technique if the RMT is <3 mm, in which case repair is essential and can be achieved by only laparoscopic or vaginal approach. Women with CSDs need to be given complete information, including available literature, before any treatment decision is made. Because prevention is better than cure, risk factors should be identified early to ensure appropriate management.

Risk of complication at the time of laparoscopic hysterectomy: a prediction model built from the National Surgical Quality Improvement Program database

BACKGROUND

Although laparoscopic hysterectomy is well established as a favorable mode of hysterectomy owing to decreased perioperative complications, there is still room for improvement in quality of care. Previous studies have described laparoscopic hysterectomy risk, but there is currently no tool for predicting risk of complication at the time of laparoscopic hysterectomy.

OBJECTIVE

This study aimed to create a prediction model for complications at the time of laparoscopic hysterectomy for benign conditions.

STUDY DESIGN

This is a retrospective cohort study that included patients who underwent laparoscopic hysterectomy for benign indications between 2014 and 2017 in US hospitals contributing to the American College of Surgeons - National Surgical Quality Improvement Program database. Data about patient baseline characteristics, perioperative complications (intraoperative complications, readmission, reoperation, need for transfusion, operative time greater than 4 hours, or postoperative medical complication), and uterine weight at the time of pathologic examination were collected retrospectively. Postoperative uterine weight was used as a proxy for preoperative uterine weight estimate. The sample was randomly divided into 2 patient populations, one for deriving the model and the other to validate the model.

RESULTS

A total of 33,123 women met the inclusion criteria. The rate of composite complication was 14.1%. Complication rates were similar in the derivation and validation cohorts (14.1% [2306 of 14,051] vs 13.9% [2289 of 14,107], P=.7207). The logistic regression risk prediction tool for hysterectomy complication identified 7 variables predictive of complication: history of laparotomy (21% increased odds of complication), age (2% increased odds of complication per year of life), body mass index (0.2% increased odds of complication per each unit increase in body mass index), parity (7% increased odds of complication per delivery), race (when compared with white women, black women had 34% increased odds and women of other races had 18% increased odds of complication), and American Society of Anesthesiologists score (when compared with American Society of Anesthesiologists 1, American Society of Anesthesiologists 2 had 31% increased odds, American Society of Anesthesiologists 3 had 62% increased odds, and American Society of Anesthesiologists 4 had 172% increased odds of complication). Predicted preoperative uterine weight also had a statistically significant nonlinear relationship with odds of complication. The c-statistics for the derivation and validation cohorts were 0.62 and 0.62, respectively. The model is well calibrated for women at all levels of risk.

CONCLUSION

The laparoscopic hysterectomy complication predictor model is a tool for predicting complications in patients planning to undergo hysterectomy.

Risk factors and long-term impact of urologic complications during radical hysterectomy for cervical cancer in China, 2004-2016

OBJECTIVE

The primary objective was to describe the incidence and risk factors of urologic complications during radical hysterectomy for cervical cancer. The secondary objective was to investigate the impact of urologic complications on long-term survival.

METHODS

Patients who underwent radical hysterectomy for cervical cancer from 2004 to 2016 were identified in the MSCCCC (Major Surgical Complications of Cervical Cancer in China) database. Data on demographic characteristics, clinical characteristics, hospital characteristics and urologic complications were collected. Multivariable logistic regression was used to assess the risk factors of urologic complications and Cox proportional hazards models were performed to identify prognostic factors.

RESULTS

A total of 21,026 patients undergoing radical hysterectomy for cervical cancer were identified. The incidence of any urologic complications was 1.54%: 83 (0.39%) ureteral injuries, 17 (0.08%) bladder injuries, 1 (0.005%) ureteral injury combined with bladder injury, and 223 (1.05%) genitourinary fistulas. In a multivariable analysis, surgery at a women and children's hospital (OR = 2.26, 95% CI 1.47-3.48), surgery at a facility in a first-tier city (OR = 2.08, 95% CI 1.24-3.48), and laparoscopic surgery (OR = 4.68, 95% CI 3.44-6.36) were associated with a higher risk of urologic complications. Cox proportional hazards models revealed that the occurrence of urologic complications was a significant predictor of 2-year overall survival (OR = 1.78, 95% CI = 1.09-2.92), but was not a predictor of 5-year overall survival (OR = 1.27, 95% CI = 0.83-1.94).

CONCLUSION

The incidence of urologic complications during radical hysterectomy is low. The risk of urologic complications may be higher for patients who are treated at a women and children's hospital, are treated in first-tier city hospitals, and receive laparoscopic surgery. Urologic complications have an impact on short-term survival, but not on long-term survival.

Perioperative Complications of Hysterectomy After a Previous Cesarean Section: A Systematic Review and Meta-Analysis

Background

With increasing rates of cesarean sections (CS), the number of hysterectomies performed among women with a previous CS is on the rise.

Objective

To provide the association between the odds of complications following a hysterectomy performed later in life and a previous CS.

Search strategy

A comprehensive search was performed using major electronic databases, ie, MEDLINE, Scopus, ISI Web of Science, from their inception to April 2019.

Selection criteria

Analytical studies, irrespective of language or publication status, were included.

Data collection and analysis

Outcomes were extracted in duplicate. The methodological quality of the included studies was independently evaluated by two review authors. A three-level meta-analysis was applied for outcomes with dependent effect sizes.

Main results

Twenty-six studies were included involving 54,815 women. The odds of the following complications were increased in women with a previous CS: urinary tract injury (pooled unadjusted odds ratio (OR)=3.15, 95% CI=2.01-4.94, 15 studies, 33,902 women, and pooled adjusted OR=2.21, 95% CI=1.46-3.34, 3 studies, 31,038 women), gastrointestinal tract injury (pooled unadjusted OR=1.73, 95% CI=1.19-2.53; 7 studies, 30,050, and pooled adjusted OR=1.83, 95% CI=1.11-3.03, 1 study, 25,354 women), postoperative infections (pooled unadjusted OR=1.44, 95% CI=1.22-1.71, 6 studies, 37,832 women), wound complications (pooled unadjusted OR=2.24, 95% CI=1.94-2.57, 9 studies, 37,559 women), reoperation (pooled unadjusted OR=1.46, 95% CI=1.19-1.78, 2 studies, 9,899 women), and blood transfusion (pooled unadjusted OR=1.35, 95% CI=1.03-1.76, 7 studies, 13,430 women).

Conclusion

Previous CS increases risks of various complications following hysterectomy. This information reminds the gynecologists to be aware of the associations between previous CS and potential complications among women undergoing hysterectomy.

Factors for cecal intubation time during colonoscopy in women: Impact of surgical history

BACKGROUND/AIM

Cecal intubation during colonoscopy is prone to be prolonged in women, which may be related to frequent exposure to pelvic/abdominal surgery. We evaluated the association between Cecal Intubation Time (CIT) and prior episodes of pelvic/abdominal surgery in women.

PATIENTS AND METHODS

A cross-sectional study was conducted on screening participants who underwent colonoscopy. Multivariate regression with parameter estimates (β) was performed to determine the factors affecting CIT, including age, body mass index (BMI), bowel preparation, sedation, diverticulosis, experience of colonoscopists, and a surgical history. Also, subgroup analyses according to type of surgery were performed.

RESULTS

A total of 835 women were enrolled. The mean CIT was 5.82 ± 3.40 min. 323 females (38.7%) had episodes of surgery. The CIT was prolonged in cases performed by non-experienced trainees (β = 3.61, P< 0.001) and with a history of gynecological surgery (β = 0.97, P = 0.001). In the subgroup of non-experienced trainees, lower BMI, poor preparation, and a history of cesarean section significantly prolonged the CIT. Also, the risk for difficult colonoscopy (CIT ≥ 15 min) was increased with a history of cesarean section (odds ratio = 4.43, P= 0.024).

CONCLUSION

A prior episode of gynecological surgery prolonged CIT. Also, cesarean section history was associated with difficult colonoscopy in the examination by non-experienced trainees.

Effect of laparoscopic versus abdominal radical hysterectomy on major surgical complications in women with stage IA-IIB cervical cancer in China, 2004-2015

OBJECTIVES

To report the trends in surgical approaches and compare the major surgical complication rates of laparoscopic and abdominal radical hysterectomy for cervical cancer.

METHODS

From the major surgical complications of cervical cancer in China (MSCCCC) database, we obtained the demographic, clinical, treatment hospital and complication data of patients with cervical cancer who underwent radical hysterectomy from 2004 to 2015 at 37 hospitals. The patients were assigned to the laparoscopic and abdominal surgery groups. The differences in the complication rates were analyzed using univariate and multivariable logistic regression models.

RESULTS

We identified a total of 18447 patients; 5491 (29.8%) underwent laparoscopic surgery and 12956 (70.2%) underwent abdominal surgery. The proportion of laparoscopic surgery rose from 0.35% in 2004 to 49.31% in 2015. In the multivariate analysis, the laparoscopic group had increased odds of intraoperative and postoperative complications (OR = 3.88, 95% CI = 2.47-6.11; OR = 1.42, 95% CI = 1.11-1.82). A more detailed analysis showed that laparoscopic surgery was associated with increased rates of intraoperative ureteral injury (OR = 3.83, 95% CI = 2.11-6.95), bowel injury (OR = 14.83, 95% CI = 1.32-167.25), vascular injury (OR = 3.37, 95% CI = 1.18-9.62), postoperative vesicovaginal fistula (OR = 4.16, 95% CI = 2.08-8.32), ureterovaginal fistula (OR = 4.16, 95% CI = 2.08-8.32), rectovaginal fistula (OR = 8.04, 95% CI = 1.63-39.53), and chylous leakage (OR = 10.65, 95% CI = 1.18-95.97), while abdominal surgery was more likely to cause bowel obstruction (OR = 0.55, 95% CI = 0.35-0.87). The two groups had similar rates of bladder injury, obturator nerve injury, pelvic hematoma, rectovaginal fistula and venous thromboembolism (P > 0.05).

CONCLUSION

Laparoscopic surgery was associated with more major surgical complications, especially intraoperative ureteral injury and postoperative fistula, than abdominal surgery among women with cervical cancer.

Prevention and management of bowel injury during gynecologic laparoscopy: an update

PURPOSE OF REVIEW

The current article aims to briefly review recent literature on bowel injury in gynecologic surgery with a focus on minimally invasive techniques, strategies for prevention, and management of injury.

RECENT FINDINGS

Recent reviews describe a low incidence of bowel injury that is likely affected by low rates of reporting and inconsistent definitions. The major risk factor for bowel injury is adhesive disease, and assessment and prevention techniques for the presence of adhesive disease are evolving. When bowel injury occurs, prompt diagnosis and intraoperative repair yields more favorable outcomes than delayed diagnosis. Repair can be performed by a gynecologic surgeon, with or without the help of a consultant depending on the extent of the injury and surgeon comfort.

SUMMARY

Bowel injury is a potentially catastrophic complication in gynecologic surgery, but its rarity presents a challenge in research. A high index of suspicion and meticulous surgical technique are the cornerstones of managing a bowel injury.

Menopausal symptoms and surgical complications after opportunistic bilateral salpingectomy, a register-based cohort study

BACKGROUND

In recent years, the fallopian tubes have been found to play a critical role in the pathogenesis of ovarian cancer. Therefore, bilateral salpingectomy at the time of hysterectomy has been proposed as a preventive procedure, but with scarce scientific evidence to support the efficiency and safety.

OBJECTIVE

Our primary objective was to evaluate the risk of surgical complications and menopausal symptoms when performing bilateral salpingectomy in addition to benign hysterectomy. Furthermore, we sought to compare time in surgery, perioperative blood loss/blood transfusion, duration of hospital stay, days to normal activities of daily living, and days out of work for hysterectomy with bilateral salpingectomy compared with hysterectomy only. A secondary objective was to study the uptake of opportunistic salpingectomy in Sweden.

STUDY DESIGN

This was a retrospective observational cohort study based on data from the National Quality Register of Gynecological Surgery in Sweden. Women <55 years of age who had a hysterectomy for benign indications with or without bilateral salpingectomy in 1998 through 2016 were included. Possible confounding was adjusted for in multivariable regression models.

RESULTS

During the study period, 23,369 women had a hysterectomy for benign indications. The frequency of bilateral salpingectomy at the time of hysterectomy increased mainly from 2013, which is why the period 2013 through mid-2016 was selected for further analysis (n = 6892). There was a low frequency of vaginal hysterectomy with bilateral salpingectomy performed in this period, which is why only abdominal and laparoscopic surgeries were selected for comparative analysis (n = 4906). This study indicates an increased risk of menopausal symptoms (adjusted relative risk, 1.33; 95% confidence interval, 1.04-1.69) 1 year after hysterectomy with bilateral salpingectomy compared with hysterectomy only. Hospital stay was 0.1 days longer in women having salpingectomy (P = .01), and bleeding was slightly reduced in the salpingectomy group (-20 mL, P = .04). Other outcome measures were not significantly associated with salpingectomy, albeit a tendency toward higher risk of minor complications was seen (adjusted relative risk, 1.30; 95% confidence interval, 0.93-1.83).

CONCLUSION

Bilateral salpingectomy at the time of hysterectomy was associated with an increased risk of menopausal symptoms 1 year after surgery. Randomized clinical trials reducing the risk of residual and unmeasured confounding and longer follow-up are needed to correctly inform women on the risks and benefits of opportunistic salpingectomy.

Risk of fistula formation and long-term health effects after a benign hysterectomy complicated by organ injury: A population-based register study

INTRODUCTION

There is a paucity of data on the impact of organ injury on long-term outcomes after a hysterectomy for benign indications. The aim of this study was to investigate fistula formation and patient-reported long-term health outcomes after organ injury at the time of a hysterectomy.

MATERIAL AND METHODS

This was a population-based study of 22 538 women undergoing a hysterectomy between 2000 and 2014 in Sweden. Their medical history, characteristics of their surgery, and patient-reported outcomes were retrieved from Swedish national health and quality registers. Predictors for fistula formation were investigated with logistic regression and are presented as odds ratios with a 95% CI.

RESULTS

Fistulas were reported in 7% of women with organ injuries, compared with 0.4% of those without organ injuries (adjusted odds ratio 15.29 [9.81-23.85]). Laparotomy and postoperative infection were associated with postoperative fistulas. Most of the women reported having better health 1 year after the hysterectomy, but 7% of those with organ injuries and 24% of those with fistulas reported deteriorated health, compared with 2% of women without injuries.

CONCLUSIONS

Organ injury at the time of hysterectomy is associated with the development of fistulas involving the female genital tract and increases the proportion of women reporting deteriorated health 1 year after surgery.
