INTRODUCTION AND HYPOTHESIS
Predictors of surgical outcomes in patients with an obstetric fistula who have been operated before should be identified in order to guide surgical strategy and optimize counseling of the patient.
METHODS
This retrospective study is aimed at identifying predictors of outcomes for repeat surgery in 346 patients who had been operated on before for an obstetrics fistula at the Fistula Care Center (FCC) in Lilongwe, Malawi. Repeat cases were only undertaken by advanced and expert surgeons. The primary outcome was successful anatomical closure, based on a negative postoperative dye test. The secondary outcomes involved urinary continence, based on a patient-reported questionnaire and an objective 1-h pad weight test. Logistic regression models were used to test the predictors for statistical significance.
RESULTS
Successful fistula closure was achieved in 288 (83%) patients and continence was achieved in 185 (64%) patients after the first repeat attempt at the FCC. Lack of urethral involvement (Goh classification: proximity to the urethra) was shown to be a good predictor of the outcomes: fistula closure and subjective and objective continence.
CONCLUSIONS
Absence of urethral involvement is an independent predictor for successful outcomes in repeat surgery for obstetric fistulas. Even in the hands of an expert surgeon, the risk of another failure in achieving anatomical closure or subjective or objective continence is between 4 and 5 times higher than when the urethra is not involved.

BACKGROUND
The population of women undergoing abdominal myomectomy for symptomatic large fibroid uterus is unique. We seek to characterize the timing, risk factors as well as the presenting symptoms which led patients to undergo repeat surgery in this patient population.
METHODS AND FINDINGS
We followed 592 patients who underwent an abdominal myomectomy from March 1998 to June 2010 at St. Vincent's Catholic Medical Center and presented later during the study period with a recurrence of symptoms attributable to a reemergence of fibroids and who chose to undergo repeat surgical management. Twelve percent of patients exhibited symptoms of fibroid uterus which led to reoperation within the study period. The mean age at repeat surgery was 44.1 ± 0.6 years old (n = 69) and the mean time between operations was 7.9 ± 0.3 years. Presentation was variable but included bleeding, pain and infertility. Patients presented for surgery with a significantly smaller sized uterus than at their initial surgery. Timing between surgeries correlated with age at initial surgery and uterine size but race, number of fibroids, aggregate weight of fibroids removed, operative time or blood loss at the initial surgery did not correlate. Data is suggestive that intraperitoneal triamcinolone may reduce reoperation rates but not timing of recurrence.
CONCLUSION
These results may help in counseling patients, particularly younger women, on the risks of fibroid recurrence necessitating repeat surgery. Further research is necessary to assess if triamcinolone can alter fibroid reurrence in patients who undergo uterus sparing procedures.

INTRODUCTION AND HYPOTHESIS
Pelvic organ prolapse (POP) surgery is a common gynecological procedure. Our aim was to assess the influence of obesity and other risk factors on the outcome of anterior and posterior colporrhaphy with and without mesh.
METHODS
Data were retrieved from the Swedish National Register for Gynecological Surgery on 18,554 women undergoing primary and repeat POP surgery without concomitant urinary incontinence (UI) surgery between 2006 and 2015. Multivariate logistic regression analyses were used to identify independent risk factors for a sensation of a vaginal bulge, de novo UI, and residual UI 1 year after surgery.
RESULTS
The overall subjective cure rate 1 year after surgery was 80% (with mesh 86.4% vs 77.3% without mesh, p < 0.001). The complication rate was low, but was more frequent in repeat surgery that were mainly mesh related. The use of mesh was also associated with more frequent de novo UI, but patient satisfaction and cure rates were higher compared with surgery without mesh. Preoperative sensation of a vaginal bulge, severe postoperative complications, anterior colporrhaphy, prior hysterectomy, postoperative infections, local anesthesia, and body mass index (BMI) ≥30 were risk factors for sensation of a vaginal bulge 1 year postsurgery. Obesity had no effect on complication rates but was associated increased urinary incontinence (UI) after primary surgery. Obesity had no influence on cure or voiding status in women undergoing repeat surgery.
CONCLUSIONS
Obesity had an impact on the sensation of a vaginal bulge and the presence of UI after primary surgery but not on complications.

BACKGROUND/AIM
Up to a third of patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal carcinomatosis (PC) of appendiceal or colorectal origin receive a stoma during primary surgery. Stoma reversal provides an opportunity for second-look surgery.
PATIENTS AND METHODS
We performed a retrospective analysis of prospectively collected data of patients with colorectal cancer (CRC) or high-grade appendiceal cancer (AC) from 2006 to 2021 from our database. A total of 34 consecutive stoma closure patients with no evidence of preoperative disease recurrence (tumor markers and CT scans) were compared with 141 consecutive re-do CRS/HIPEC patients with known recurrence.
RESULTS
Eleven patients (32.4%) were identified to have peritoneal recurrence at stoma closure. Time between first and second CRS was 12 months (4 to 64.2) in the stoma closure group vs. 24.6 months (5.8 to 119.8) in the re-do group, while median peritoneal cancer index (PCI) was 4 (3 to 6) vs. 8 (1 to 39), respectively (p=0.0143).
CONCLUSION
Second-look laparotomy during stoma closure identified unexpected PC in 32.4% of our patients with significantly lower PCI than planned re-do operations.

Meta-Analysis Review
BACKGROUND
Pelvic adhesions can form as a result of inflammation, endometriosis or surgical trauma. During pelvic surgery, strategies to reduce pelvic adhesion formation include placing barrier agents such as oxidised regenerated cellulose, polytetrafluoroethylene or fibrin sheets between the pelvic structures.
OBJECTIVES
To evaluate the effects of barrier agents used during pelvic surgery on rates of pain, live birth and postoperative adhesions in women of reproductive age.
SEARCH METHODS
We searched the following databases in February 2015: the Menstrual Disorders and Subfertility Group (MDSG) Specialised Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Central Register of Controlled Trials (CENTRAL) and trial registries. We handsearched relevant journals, conference proceedings and grey literature sources and we contacted pharmaceutical companies for information.
SELECTION CRITERIA
Randomised controlled trials (RCTs) of the use of barrier agents compared with other barrier agents, placebo or no treatment for the prevention of adhesions in women undergoing gynaecological surgery.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for eligibility and risk of bias and extracted the data. We calculated odds ratios (ORs) or mean differences (MD) with 95% confidence intervals (CIs) using a fixed effect model. The overall quality of the evidence was assessed using GRADE (Grades of Recommendation, Assessment, Development and Evaluation) methods.
MAIN RESULTS
Eighteen RCTs (1262 women) were included. Six RCTs randomised women; the remainder randomised pelvic organs. Laparoscopy (eight RCTs) and laparotomy (10 RCTs) were the primary surgical techniques. Indications for surgery included myomectomy (six RCTs), ovarian surgery (five RCTs), pelvic adhesions (five RCTs), endometriosis (one RCT) and mixed (one RCT). The sole indication for surgery in three of the RCTs was infertility. Twelve RCTs reported commercial funding; the rest did not state their source of funding.No studies reported either of our primary outcomes of pelvic pain and live birth. Oxidised regenerated cellulose (Interceed) versus no treatment at laparoscopy or laparotomy (13 RCTs)At second-look laparoscopy oxidised regenerated cellulose at laparoscopy was associated with reduced incidence of de novo adhesions (OR 0.50, 95% CI 0.30 to 0.83, three RCTs, 360 participants, I(2) = 75%, very low-quality evidence) and of re-formed adhesions (OR 0.17, 95% CI 0.07 to 0.41, three RCTs, 100 participants, I(2) = 36%, low quality evidence).At second-look laparoscopy no evidence was found of any difference between the groups in the incidence of de novo adhesions after laparotomy (OR 0.72, 95% CI 0.42 to 1.25, one RCT, 271 participants, I(2) = 41%, low-quality evidence). However, the incidence of re-formed adhesions was lower in the intervention group (OR 0.38, 95% CI 0.27 to 0.55, six RCTs, 554 participants, moderate-quality evidence). Expanded polytetrafluoroethylene (Gore-Tex) versus no treatment at gynaecological surgery (one RCT) The evidence suggested that at second-look laparoscopy expanded polytetrafluoroethylene was associated with a reduction in new adhesion formation (OR 0.17, 95% CI 0.03 to 0.94, one RCT, 42 participants, low-quality evidence). Expanded polytetrafluoroethylene (Gore-Tex) versus oxidised regenerated cellulose (Interceed) at gynaecological surgery (two RCTs)One RCT found no difference between the groups at second-look laparoscopy in the incidence of de novo adhesions (OR 0.93, 95% CI 0.26 to 3.41, 38 participants, very low-quality evidence). A second RCT suggested that the expanded polytetrafluoroethylene group had a lower adhesion score (out of 11) (MD -3.79, 95% CI -5.12 to -2.46, 62 participants, very low-quality evidence) and a lower risk of re-formed adhesions (OR 0.13, 95% CI 0.02 to 0.80, 23 participants, very low-quality evidence). This last finding was sensitive to choice of effect estimate and no longer suggested a difference between the groups when a risk ratio was calculated (RR 0.36, 95% CI 0.13 to 1.01). Sodium hyaluronate and carboxymethylcellulose (Seprafilm) versus no treatment at gynaecological surgery (one RCT)Sodium hyaluronate and carboxymethylcellulose was associated with a lower adhesion score (out of 4) at second-look laparoscopy (MD 0.49, 95% CI 0.53 to 0.45, one RCT, 127 participants, moderate-quality evidence). Fibrin sheet versus no treatment at laparoscopic myomectomy (one RCT)There was no evidence of a difference between the groups in the incidence of de novo adhesions at second-look laparoscopy (OR 1.20, 95% CI 0.42 to 3.41, one RCT, 62 participants) or in adhesion score (out of 4) (MD 0.14, 95% CI -0.67 to 0.39, one RCT, 48 participants, low-quality evidence).Fourteen of the 18 RCTs reported adverse events. No events directly attributed to adhesion agents were reported.
AUTHORS' CONCLUSIONS
We found no evidence on the effects of barrier agents used during pelvic surgery on either pain or fertility outcomes in women of reproductive age.Low quality evidence suggests that oxidised regenerated cellulose (Interceed), expanded polytetrafluoroethylene (Gore-Tex) and sodium hyaluronate with carboxymethylcellulose (Seprafilm) may all be more effective than no treatment in reducing the incidence of adhesion formation following pelvic surgery. There is no conclusive evidence on the relative effectiveness of these interventions. There is no evidence to suggest that fibrin sheet is more effective than no treatment. No adverse events directly attributed to the adhesion agents were reported. The quality of the evidence ranged from very low to moderate. The most common limitations were imprecision and poor reporting of study methods. Most studies were commercially funded, and publication bias could not be ruled out.

OBJECTIVES/HYPOTHESIS
Endoscopic sinus surgery (ESS) is performed for patients with chronic rhinosinusitis (CRS) that have failed maximal medical therapy. This study seeks to determine the prevalence of revision surgery and factors predicting the need for revision after ESS using a large statewide surgery database.
STUDY DESIGN
Large retrospective cohort study using the State Ambulatory Surgery Database for the state of California between 2005 and 2011.
METHODS
We identified over 61,000 patients with CRS who underwent ESS, determined by Current Procedural Terminology code. We identified which patients underwent a repeat surgery, and performed multivariable modeling to determine which factors (nasal polyps, age, gender, insurance, hospital setting, ethnicity) predicted the need for revision. Adjusted odds ratios (AOR) and 95% confidence intervals are presented.
RESULTS
Of 61,339 patients who underwent ESS, 4,078 (6.65%) returned for revision ESS during the time period investigated. In a multivariable logistic regression model, positive predictors of revision were a diagnosis of nasal polyps (AOR: 1.20, 95% CI: 1.11-1.29, P < .001) and female gender (AOR: 1.20, 95% CI: 1.11-1.29, P < .001); public insurance was marginally predictive of increased reoperation (AOR: 1.10, 95% CI: 1.00-1.21, P = .048). Patients of Hispanic ethnicity were less likely to have revision surgery (AOR: 0.86, 95% CI: 0.77-0.97, P = .011). Age, income, and hospital setting were not significant predictors.
CONCLUSIONS
A minority of patients with CRS who undergo ESS will have a revision surgery. This likelihood is increased in female patients and those with nasal polyps, and decreased in patients of Hispanic ethnicity, even when controlling for income, insurance, and hospital setting.

BACKGROUND
Despite the growing number of studies reporting on periprosthetic joint infection (PJI), there is little information on one-stage exchange arthroplasty for the revision of infected rotating-hinge prostheses, which can be among the most difficult PJI presentations to treat.
QUESTIONS/PURPOSES
After one-stage direct exchange revision for an infected rotating-hinge TKA prosthesis, and using a multimodal approach for infection control, we asked: (1) What is the survivorship free from repeat revision for infection and survivorship free from reoperation for any cause? (2) What is the clinical outcome, based on the Oxford Knee Score, of these patients at the latest follow-up?
METHODS
Between January 2011 and December 2017, we treated 101 patients with infected rotating-hinge knee prostheses at our hospital. All patients who underwent a one-stage exchange using another rotating-hinge implant were potentially eligible for this retrospective study. During that period, we generally used a one-stage approach when treating PJIs. Eighty-three percent (84 of 101) of patients were treated with one-stage exchange, and the remainder were treated with two-stage exchange. Of the 84 treated with one-stage exchange, eight patients died of unrelated causes and were therefore excluded, one patient declined to participate in the study, and another eight patients were lost before the minimum study follow-up of 2 years or had incomplete datasets, leaving 80% (67 of 84) for analysis in this study. The included study population consisted of 60% males (40 of 67) with a mean age of 64 ± 8 years and a mean (range) BMI of 30 ± 6 kg/m2 (21 to 40). The mean number of prior surgeries was 4 ± 2 (1 to 9) on the affected knee. Fifteen percent (10 of 67) of knees had a preoperative joint communicating sinus tract, and 66% (44 of 67) had experienced a prior PJI on the affected knee. The antimicrobial regimen was chosen based on the advice of our infectious disease consultant and individually adapted for the organism cultured. The mean follow-up duration was 6 ± 2 years. Kaplan-Meier survivorship analysis was performed using the endpoints of survivorship free from repeat revision for infection and survivorship free from all-cause revision. The functional outcome was assessed using the Oxford Knee Score (on a 12- to 60-point scale, with lower scores representing less pain and greater function), obtained by interviewing patients for this study at their most recent follow-up visit. Preoperative scores were not obtained.
RESULTS
The Kaplan-Meier analysis demonstrated an overall survivorship free from reoperation for any cause of 75% (95% CI 64% to 87%) at the mean follow-up of 6 years postoperatively. Survivorship free from any repeat operative procedure for infection was 90% (95% CI 83% to 97%) at 6 years. The mean postoperative Oxford Knee Score was 37 ± 11 points.
CONCLUSION
With an overall revision rate of about 25% at 6 years and the limited functional results based on the poor Oxford Knee Scores, patients should be counseled to have modest expectations concerning postoperative pain and function level after one-stage exchange of an infected rotating-hinge arthroplasty. Nevertheless, patients may be informed about a reasonable chance of PJI eradication and might opt for this approach as a means to try to avoid high transfemoral amputation or joint arthrodesis, which in this population often is associated with the inability to ambulate at all. Regarding the relatively high number of patients with aseptic loosening, future studies might focus on implant design of revision knee systems as well. A longer course of oral antibiotics after such procedures may also be warranted to limit the chance of reinfection but requires further study.

BACKGROUND
Short and long-term outcomes after repeat anti-reflux surgery (RARS) are still debated and generally not considered as satisfying as after primary anti-reflux surgery (PARS). The aim of this study was to evaluate functional outcomes after RARS and risk factors associated to intra-operative and post-operative complications.
METHODS
This is a multicenter retrospective survey from four European laparoscopic centers. Patients who underwent elective RARS from January 2005 to October 2017 for dysphagia or for persistent reflux disease refractory to medical treatment were analyzed. Data on demographic characteristics, including type and timing of previous operations as well as intra-operative details (surgical technique, type of RARS, conversion to open surgery, prosthetic material placement) were collected. Patients who underwent operations in the emergency setting, interventions mixed with bariatric procedures and PARS performed in other surgical departments were not included in this study. Primary endpoint of this study was to evaluate risk factors associated with intraoperative and postoperative complications. Secondary endpoint was to evaluate clinical outcomes and to identify any possible correlation with clinical and surgical parameters.
RESULTS
Among 1662 patients who underwent PARS, failure occurred in 174 (10.5%) patients. Repeat surgery was performed in 117 (7%) patients, after a mean time of 80 months (range 4-315). RARS was carried out laparoscopically in 88% of cases. Prosthetic mesh to reinforce hiatoplasty was used in 22.2% of patients. Intra-operative upper gastro-intestinal tract's injuries occurred in 6 (5.1%) patients. Perioperative mortality was nil and 13 (11.1%) patients experienced postoperative complications. Mean length of hospital stay was 9.6 ± 6.4 days. Based on a multivariable analysis, age >70 years (OR 1.074, C.I.95% 1.018-1.133, p = 0.008) and body mass index (BMI) < 23 (OR 0.172, C.I.95% 0.052-0.568, p = 0.004) were independently associated to postoperative complications. After a mean follow-up time of 36 months (range 6-107), 24 (20.5%) patients presented recurrent symptoms. Based on a multivariable analysis, early onset of dysphagia (OR 3.539, C.I.95% 1.254-9.990, p = 0.017), open approach (OR 4.505, C.I.95% 1.314-15.442, p = 0.016) and the use of prosthetic material (OR 2.790, C.I.95% 0.930-8.776, p = 0.047) were significantly associated to good clinical outcomes.
CONCLUSIONS
Repeat anti-reflux surgery is a safe and feasible procedure in high-volume centers, with acceptable perioperative outcomes. Long-term results are favorable with a success rate of almost 80%. Advanced age (>70 years) and low BMI (<23 kg/m) were factor predicting perioperative complications. The use of prosthesis for hiatoplasty was associated to better functional outcomes.

Predicting tumor response and outcome of second-look surgery with F-FDG PET/CT: insights from the GINECO CHIVA phase II trial of neoadjuvant chemotherapy plus nintedanib in stage IIIc-IV FIGO ovarian cancer.
BACKGROUND
This ancillary study aimed to evaluate F-FDG PET parameter changes after one cycle of treatment compared to baseline in patients receiving first-line neoadjuvant anti-angiogenic nintedanib combined to paclitaxel-carboplatin chemotherapy or chemotherapy plus placebo and to evaluate the ability of F-FDG PET parameters to predict progression-free survival (PFS), overall survival (OS), and success of second-look surgery.
MATERIALS AND METHODS
Central review was performed by two readers blinded to the received treatment and to the patients' outcome, in consensus, by computing percentage change in PET metrics within a volume of interest encompassing the entire tumor burden. EORTC and PERCIST criteria were applied to classify patients as responders (partial metabolic response and complete metabolic response) or non-responders (stable metabolic disease and progressive metabolic disease). Also analyzed was the percentage change in metabolic active tumor volume (MATV) and total lesion glycolysis (TLG).
RESULTS
Twenty-four patients were included in this ancillary study: 10 received chemotherapy + placebo and 14 chemotherapy + nintedanib. PERCIST and EORTC criteria showed similar discriminative power in predicting PSF and OS. Variation in MATV/TLG did not predict PFS or OS, and no optimal threshold could be found for MATV/TLG for predicting survival. Complete cytoreductive surgery (no residual disease versus residual disease < 0.25 cm/0.25-2.5 cm/> 2.5 cm) was more frequent in responders versus non-responders (P = 0.002 for PERCIST and P = 0.02 for EORTC criteria). No correlation was observed between the variation of PET data and the variation of CA-125 blood level between baseline sample and that performed contemporary to the interim PET, but a statistically significant correlation was observed between ΔSUL and ΔCA-125 between baseline sample and that performed after the second cycle.
CONCLUSION
F-FDG PET using EORTC or PERCIST criteria appeared to be a useful tool in ovarian cancer trials to analyze early tumor response, and predict second-look surgery outcome and survival. An advantage of PERCIST is the correlation of ΔSUL and ΔCA-125, PET response preceding tumor markers response by 1 month. Neither MATV nor TLG was useful in predicting survival.
