Risk Factors and Outcomes of Conversion to Open Surgery in Benign Gynecologic Laparoscopies: A Case-Control Study.

STUDY OBJECTIVE: To describe cases of conversion from gynecologic laparoscopy to open surgery and to assess risk factors for conversion and conversion outcomes. DESIGN: A retrospective case-control study. SETTING: Tertiary referral hospital in Melbourne, Australia. PATIENTS: Eighty-five cases of conversion from laparoscopy to laparotomy and 170 controls matched by age, surgical date, and gynecologic unit from 2006 to 2017. INTERVENTIONS: Demographic, clinical, and surgical data were collected and compared between the study groups. Logistic regression was performed to identify preoperative and intraoperative risk factors for conversion. MEASUREMENTS AND MAIN RESULTS: Rate of conversion during the study period was 0.7%. The most common indication for conversion was unexpected surgical complexity (67% of cases), which included severe adhesive disease, specimen size, severe pathology, and inadequate views. Factors that were significantly associated with risk of conversion in multivariate analysis were previous pelvic inflammatory disease (adjusted odds ratio [aOR] 5.16; 95% confidence interval [CI], 1.35-19.71; p = .02), previous open surgery (aOR 3.62; 95% CI, 1.52-8.58; p <.01), history of endometriosis (aOR 2.96; 95% CI, 1.17-7.50; p = .02), and elevated body mass index (aOR 1.07; 95% CI, 1.01-1.13; p = .02). As compared with current surgery for endometriosis, odds of conversion were higher in surgeries for emergency indications (aOR 5.40; 95% CI, 1.53-18.98; p <.01), uterine pathologies (aOR 3.34; 95% CI, 1.10-10.12; p = .03), and adnexal pathologies (aOR 2.76; 95% CI, 1.19-6.40; p = .02). With the inclusion of intraoperative factors, surgical adhesions were also found to be associated with conversion (aOR 3.19; 95% CI, 1.30-7.85; p = .01). Most skilled laparoscopic surgeon level as defined by the Australasian Gynaecological Endoscopy and Surgery Society was not associated with conversion risk. Conversion to laparotomy was associated with a higher rate of intraoperative and postoperative complications and prolonged length of stay. CONCLUSION: Conversion to laparotomy is a rare but very important clinical outcome measure of laparoscopic surgery. Understanding the factors contributing to conversion and perioperative outcomes may help clinicians to identify and counsel patients before surgery and to reduce surgical morbidity.

Laparoscopic Oophorectomy to Treat Pelvic Pain FollowingOvary-Sparing Hysterectomy: Factors Associated with Surgical Complications and Pain Persistence.

STUDY OBJECTIVE: To examine the surgical management and outcomes of patients treated laparoscopically for pelvic pain following ovary-sparing hysterectomy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: General gynecology unit at a tertiary university hospital. PATIENTS: A total of 99 patients treated with laparoscopic oophorectomy for pelvic pain following ovary-sparing hysterectomy between January 2008 and December 2016. INTERVENTIONS: Laparoscopic oophorectomy was performed in all patients. MEASUREMENTS AND MAIN RESULTS: The patients undergoing surgery had a mean age of 48.9 years and a mean body mass index (BMI) of 28.1. They reported a mean of 3.0 previous abdominal surgeries. Sixty percent of patients reported previous abdominal hysterectomy, 21% had previous laparoscopic hysterectomy, and 19% had previous vaginal hysterectomy. At a 6-week follow-up, 59.5% of patients reported resolution of symptoms, 10.7% reported persistent symptoms, and 29.8% reported improved but not resolved symptoms. Younger patients and those reporting a previous history of gastrointestinal disease were more likely to report persistent pain at follow-up. Thirteen percent of patients had intraoperative (6%) or postoperative complications (7%), and there was a 2% rate of conversion to laparotomy. Patients at greater risk of intraoperative complications were those with a higher BMI, a greater number of previous open abdominal surgeries, or severe adhesions noted at the time of procedure. CONCLUSIONS: Laparoscopic oophorectomy to treat pelvic pain following ovary-sparing hysterectomy is a feasible yet challenging procedure. Despite a significant rate of complications and a small proportion of patients reporting persistent symptoms, most experience symptom resolution or improvement after such surgery. Further studies are needed to assess long-term outcomes. Careful patient selection and counseling are critical before this procedure.

Collective action for implementation: a realist evaluation of organisational collaboration in healthcare.

BACKGROUND: Increasingly, it is being suggested that translational gaps might be eradicated or narrowed by bringing research users and producers closer together, a theory that is largely untested. This paper reports a national study to fill a gap in the evidence about the conditions, processes and outcomes related to collaboration and implementation. METHODS: A longitudinal realist evaluation using multiple qualitative methods case studies was conducted with three Collaborations for Leadership in Applied Health Research in Care (England). Data were collected over four rounds of theory development, refinement and testing. Over 200 participants were involved in semi-structured interviews, non-participant observations of events and meetings, and stakeholder engagement. A combined inductive and deductive data analysis process was focused on proposition refinement and testing iteratively over data collection rounds. RESULTS: The quality of existing relationships between higher education and local health service, and views about whether implementation was a collaborative act, created a path dependency. Where implementation was perceived to be removed from service and there was a lack of organisational connections, this resulted in a focus on knowledge production and transfer, rather than co-production. The collaborations' architectures were counterproductive because they did not facilitate connectivity and had emphasised professional and epistemic boundaries. More distributed leadership was associated with greater potential for engagement. The creation of boundary spanning roles was the most visible investment in implementation, and credible individuals in these roles resulted in cross-boundary work, in facilitation and in direct impacts. The academic-practice divide played out strongly as a context for motivation to engage, in that 'what's in it for me' resulted in variable levels of engagement along a co-operation-collaboration continuum. Learning within and across collaborations was patchy depending on attention to evaluation. CONCLUSIONS: These collaborations did not emerge from a vacuum, and they needed time to learn and develop. Their life cycle started with their position on collaboration, knowledge and implementation. More impactful attempts at collective action in implementation might be determined by the deliberate alignment of a number of features, including foundational relationships, vision, values, structures and processes and views about the nature of the collaboration and implementation.
