  • Impact of the 2014 Food and Drug Administration Warnings Against Power Morcellation JOURNAL OF MINIMALLY INVASIVE GYNECOLOGY Lum, D. A., Sokol, E. R., Berek, J. S., Schulkin, J., Chen, L., McElwain, C., Wright, J. D. 2016; 23 (4): 548-556

    Abstract

    To determine whether members of the AAGL Advancing Minimally Invasive Gynecologic Surgery Worldwide (AAGL) and members of the American College of Obstetricians and Gynecologists Collaborative Ambulatory Research Network (ACOG CARN) have changed their clinical practice based on the 2014 Food and Drug Administration (FDA) warnings against power morcellation.A survey study.Participants were invited to complete this online survey (Canadian Task Force classification II-2).AAGL and ACOG CARN members.An online anonymous survey with 24 questions regarding demographics and changes to clinical practice during minimally invasive myomectomies and hysterectomies based on the 2014 FDA warnings against power morcellation.A total of 615 AAGL members and 54 ACOG CARN members responded (response rates of 8.2% and 60%, respectively). Before the FDA warnings, 85.8% and 86.9%, respectively, were using power morcellation during myomectomies and hysterectomies. After the FDA warnings, 71.1% and 75.8% of respondents reported stopping the use of power morcellation during myomectomies and hysterectomies. The most common reasons cited for discontinuing the use of power morcellation or using it less often were hospital mandate (45.6%), the concern for legal consequences (16.1%), and the April 2014 FDA warning (13.9%). Nearly half of the respondents (45.6%) reported an increase in their rate of laparotomy. Most (80.3%) believed that the 2014 FDA warnings have not led to an improvement in patient outcomes and have led to harming patients (55.1%).AAGL and ACOG CARN respondents reported decreased use of power morcellation during minimally invasive gynecologic surgery after the 2014 FDA warnings, the most common reason cited being hospital mandate. Rates of laparotomy have increased. Most members surveyed believe that the FDA warnings have not improved patient outcomes.

  • Techniques in minimally invasive surgery for advanced endometriosis. Current opinion in obstetrics & gynecology King, C. R., Lum, D. 2016; 28 (4): 316-22

    Abstract

    Surgery can be an important treatment option for women with symptomatic endometriosis. This review summarizes the recommended preoperative work up and techniques in minimally invasive surgery for treatment of deeply infiltrating endometriosis (DIE) involving the obliterated posterior cul-de-sac, bowel, urinary tract, and extrapelvic locations.Surgical management of DIE can pose a challenge to the gynecologic surgeon given that an extensive dissection is usually necessary. Given the high risk of recurrence, it is vital that an adequate excision is performed. With improved imaging modalities, preoperative counseling and surgical planning can be optimized. It is essential to execute meticulous surgical technique and include a multidisciplinary surgical team when indicated for optimal results.Advanced laparoscopic skills are often necessary to completely excise DIE. A thorough preoperative work up is essential to provide correct patient counseling and incorporation of the preferred surgical team to decrease complications and optimize surgical outcomes. Surgical management of endometriosis is aimed at ameliorating symptoms and preventing recurrence.

  • Obesity and older age as protective factors for vaginal cuff dehiscence following total hysterectomy. Gynecological surgery Donnellan, N. M., Mansuria, S., Aguwa, N., Lum, D., Meyn, L., Lee, T. ; 12 (2): 89-93

    Abstract

    Studies have shown an increased risk of vaginal cuff dehiscence following total laparoscopic hysterectomy (TLH). Patient variables associated with dehiscence have not been well described. This study aims to identify factors associated with dehiscence following varying routes of total hysterectomy. This is a retrospective, matched, case-control study of women who underwent a total hysterectomy at a large, urban, university-based teaching hospital from January 2000 to December 2011. Women who underwent a total hysterectomy and had a dehiscence (n = 31) were matched by surgical mode to the next five total hysterectomies (n = 155). Summary statistics and conditional logistic regression were performed to compare cases to controls. Obese women (BMI ≥ 30) were 70 % less likely than normal weight women (BMI < 25) to experience a dehiscence (p = 0.02). When stratified by hysterectomy route, obese women were 86 % less likely to have a dehiscence following robotic-assisted total hysterectomy (RAH) and TLH than normal weight women (p = 0.04). Further, increasing age was protective of dehiscence in this subgroup of women (p = 0.02). Older age and obesity were associated with a decreased risk of dehiscence following RAH and TLH but not following other routes. Increased risk of dehiscence following TLH observed in previous studies may be partially due to patient characteristics.

  • Utilization of and charges for robotic versus laparoscopic versus open surgery for endometrial cancer JOURNAL OF SURGICAL ONCOLOGY Yu, X., Lum, D., Kiet, T. K., Fuh, K. C., Orr, J., Brooks, R. A., Ueda, S. M., Chen, L., Kapp, D. S., Chan, J. K. 2013; 107 (6): 653-658

    Abstract

    To analyze the utilization and hospital charges associated with robotic (RS) versus laparoscopic (LS) versus open surgery (OS) in endometrial cancer patients.Hospital discharge data were extracted from Florida Agency for Health Care Administration between October 2008 and December 2009.Of 2,247 patients (median age: 64 years), 29% had RS, 10% had LS, and 61% had OS. The mean length of hospital stay was 1.6, 1.8, and 3.9 days for RS, LS, and OS, respectively (P < 0.001). The median hospital charge was $51,569, $37,202, and $36,492, for RS, LS, and OS (P < 0.001), with operating room charges ($22,600, $13,684, and $11,272) accounting for the major difference. Robotic surgery utilization increased by 11% (23-34%) over time.In this statewide analysis of endometrial cancer patients, the utilization of robotic surgery increased and is associated with higher hospital charges compared to laparoscopic and open procedures.

  • Cytologic Findings in Experimental in vivo Fallopian Tube Brush Specimens ACTA CYTOLOGICA Rodriguez, E. F., Lum, D., Guido, R., Austin, R. M. 2013; 57 (6): 611-618

    Abstract

    The fallopian tube is now recognized as a primary source of precursor neoplastic lesions for pelvic serous adenocarcinomas. Cytologic features of fallopian tube brushings from low-risk patients have not been well described.We describe the cytomorphology of tubal epithelium from prospectively collected experimental in vivo brushings from normal fallopian tubes of 7 low-risk patients. Liquid-based cytology slides and cell blocks were prepared and reviewed on all specimens.Fifteen brush cytology specimens were obtained, ten by laparoscopy, four by hysteroscopy and one following hysterectomy and bilateral salpingo-oophorectomy on an ex vivo specimen. Variable cytologic features were documented for background, cellularity, cellular architecture, cilia, nuclear overlap, mitoses, nuclear pleomorphism, nuclear membrane changes and nucleoli. Negative P53 and Ki-67 stain results were documented in available cell blocks. Histopathologic salpingectomy findings and clinical follow-up were benign.Moderate nuclear pleomorphism and nuclear overlap, prominent single and multiple nucleoli and background granular debris were common challenging cytologic findings in fallopian tube brushings from low-risk patients. With experience, cellular changes can be recognized as benign. Recognition of the range of normal fallopian tube cytology should help to minimize false-positive interpretations of cytology specimens obtained in association with risk-reducing salpingo-oophorectomies.
