Direct Subscarpal Lipectomy Combined With Liposuction in Abdominoplasty: An Analysis of Safety and Efficacy in 200 Consecutive Patients.

BACKGROUND: Abdominoplasty procedures continue to evolve because combining techniques such as suction-assisted lipectomy or direct subscarpal lipectomy have proven to be powerful adjuncts to achieve optimal aesthetic results. However, concern has been expressed about combining techniques simultaneously given the potential to damage the vascularity of the abdominoplasty flap. OBJECTIVES: The aim of this study was to assess the safety and efficacy of simultaneous direct subscarpal lipectomy combined with liposuction in abdominoplasty patients. METHODS: A 4-year retrospective review of consecutive abdominoplasties (n = 200) performed by a single surgeon was conducted. Liposuction of the abdominal flap and flanks was performed in all patients. After raising the abdominoplasty flap, undermining was performed to just beyond the xyphoid, the lower rib margins superiorly, and the anterior axillary line laterally. Fat deep to Scarpa's fascia was then removed by direct tangential excision in all zones of the abdominal flap. RESULTS: The patients had a mean age of 42.19 years and BMI of 28.10 kg/m2; the mean follow-up time was 7 months. Seroma occurred in 13 patients (6.5%), superficial wound dehiscence treated with local wound care in 16 patients (8%), hypertrophic scarring in 16 patients (8%), partial umbilical necrosis in 1 patient (0.5%), and partial umbilical epidermolysis in 6 patients (3%). No patients experienced major or minor full-thickness tissue loss. No patients needed reoperation. CONCLUSIONS: Simultaneous direct excision of subscarpal fat with liposuction of the abdomen and flanks does not appear to subject any zone of the abdominoplasty flap to increased risks of vascular compromise. No flap necroses were observed. The technique described is safe and may provide superior abdominoplasty results.

Treatment of Surgical Scars With Combination Pulsed Dye and Fractional Nonablative Laser: A Randomized Controlled Trial.

OBJECTIVE: To assess the effectiveness and safety of combined pulsed-dye laser (PDL) and NAFL for treatment of surgical scars. SUMMARY BACKGROUND DATA: PDL and NAFL have not been compared to healing by time alone. METHODS: Randomized controlled, single-blinded clinical trial at an urban, university hospital. Healthy adults' status post skin surgery with primary closure were randomized to either 3 sessions of combination PDL and NAFL every 2 to 8 weeks, or control of no treatment. At baseline and 36-week follow-up, Patient and observer Scar Assessment Scale and Scar Cosmesis Assessment and Rating were completed by participants and blinded physicians. The primary outcome was scar improvement, as measured by the score difference over time. RESULTS: Of 76 participants, 52 completed the study (July 2017 to June 2019). No severe adverse events were reported. Patient and observer Scar Assessment Scale assessments demonstrated improvement in total score in the laser group compared to controls, as reported by patients [mean difference (standard deviation), laser: 12.86 (6.91) vs control: 7.25 (6.34); P = 0.004] and blinded physicians [18.32 (8.69) vs 13.08 (9.63); P = 0.044]. Patients observed a greater improvement in scar thickness [3.68 (2.04) vs 1.88 (1.85); P = 0.002] and stiffness [3.57 (2.78) vs 1.50 (2.11); P = 0.004] with lasers, and physicians reported greater improvement in vascularity [3.71 (1.98) vs 1.71 (1.52); P = 0.0002]. The live Scar Cosmesis Assessment and Rating subscore for erythema improved significantly with lasers [1.04 (0.79) vs 0.42 (0.50); P = 0.001]. CONCLUSIONS AND RELEVANCE: Combined PDL and NAFL resulted in scar improvement. Scar thickness, stiffness, and erythema were improved. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03057964).

Development of a core outcome set for basal cell carcinoma.

BACKGROUND: There is variation in the outcomes reported in clinical studies of basal cell carcinoma. This can prevent effective meta-analyses from answering important clinical questions. OBJECTIVE: To identify a recommended minimum set of core outcomes for basal cell carcinoma clinical trials. METHODS: Patient and professional Delphi process to cull a long list, culminating in a consensus meeting. To be provisionally accepted, outcomes needed to be deemed important (score, 7-9, with 9 being the maximum) by 70% of each stakeholder group. RESULTS: Two hundred thirty-five candidate outcomes identified via a systematic literature review and survey of key stakeholders were reduced to 74 that were rated by 100 health care professionals and patients in 2 Delphi rounds. Twenty-seven outcomes were provisionally accepted. The final core set of 5 agreed-upon outcomes after the consensus meeting included complete response; persistent or serious adverse events; recurrence-free survival; quality of life; and patient satisfaction, including cosmetic outcome. LIMITATIONS: English-speaking patients and professionals rated outcomes extracted from English language studies. CONCLUSION: A core outcome set for basal cell carcinoma has been developed. The use of relevant measures may improve the utility of clinical research and the quality of therapeutic guidance available to clinicians.

Desymmetrization of Diols by Phosphorylation with a Titanium-BINOLate Catalyst.

The desymmetrization of ten prochiral diols by phosphoryl transfer with a titanium-BINOLate complex is discussed. The phosphorylation of nine 1,3-propane diols is achieved in yields of 50-98%. Enantiomeric ratios as high as 92:8 are achieved with diols containing a quaternary C-2 center incorporating a protected amine. The chiral ligand, base, solvent, and stoichiometry are evaluated along with a nonlinear effect study to support an active catalyst species that is oligomeric in chiral ligand. The use of pyrophosphates as the phosphorylating agent in the desymmetrization facilitates a user-friendly method for enantioselective phosphorylation with desirable protecting groups (benzyl, o-nitrobenzyl) on the phosphate product.

Gluteal Vein Anatomy: Location, Caliber, Impact of Patient Positioning, and Implications for Fat Grafting.

BACKGROUND: Deaths in gluteal autografting occur due to gluteal vein injuries, but data are lacking on the precise location and caliber of these veins. OBJECTIVES: The authors sought to present the first in vivo study of gluteal vein anatomy utilizing magnetic resonance imaging. METHODS: Magnetic resonance imaging venography of 16 volunteer hemi-sections was conducted in the supine, prone, prone with a bump (jack-knife), and left and right decubitus positions in 1 session after a single contrast administration. Caliber and course of the superior and inferior gluteal veins (SGV/IGV) were analyzed vs bony landmarks and position changes. RESULTS: The SGV has a very short submuscular course before splitting into 2 smaller branches superolaterally. The IGV runs immediately deep to the gluteus maximus in the center of the buttock as a single large trunk, on average 56 mm deep (mean 27 mm of muscle belly and 30 mm subcutaneous fat). No intramuscular or subcutaneous branches greater than 2 mm were found. In the prone position, the IGV and SGV have an average caliber of 5.96 mm and 5.63 mm. Vessel caliber decreased by 21% and 27%, respectively, in the jack-knife position and by 14% and 15% in lateral decubitus. CONCLUSIONS: The SGV and IGV are immediately deep to gluteus maximus approximately 6 cm deep with a caliber on the order of 6 mm in the prone position. The distribution of these vessels suggests there is no "safe zone" in the intramuscular or submuscular planes. The jackknife or lateral decubitus positions can decrease vein caliber by up to 27%, possibly reducing the risk of injury due to either traction or direct cannula impact.

Complications in Postmastectomy Breast Reconstruction: One-year Outcomes of the Mastectomy Reconstruction Outcomes Consortium (MROC) Study.

OBJECTIVE: In postmastectomy reconstruction, procedure choice is heavily influenced by the relative risks of the various options. This study sought to evaluate complications in a large, multicenter patient population. SUMMARY OF BACKGROUND DATA: Previous studies have reported widely varying complication rates, but have been limited by their single center designs and inadequate controlling for confounders in their analyses. METHODS: Eleven sites enrolled women undergoing first time, immediate, or delayed reconstruction following mastectomy for cancer treatment or prophylaxis. Procedures included expander/implant, latissimus dorsi (LD), pedicle transverse rectus abdominis musculocutaneous (PTRAM), free TRAM (FTRAM), and deep inferior epigastric perforator (DIEP) techniques. Data were gathered pre- and postoperatively from medical records. Separate logistic regressions were conducted for all complications and major complications (those requiring rehospitalization and/or reoperation) within 1 year. Odds ratios (ORs) were calculated for procedure type, controlling for site, demographic, and clinical variables. RESULTS: Complication rates for 2234 patients were analyzed. Compared with expander/implant reconstructions, LD (OR) 1.95, P = 0.026), PTRAM (OR 1.89, P = 0.025), FTRAM (OR 1.94, P = 0.011), and DIEP (OR 2.22, P < 0.001) procedures were associated with higher risks of complications. Significantly higher risks were also associated with older age, higher body mass index (BMI), immediate reconstruction, bilateral procedures, and radiation. For major complications, regression showed significantly greater risks for PTRAM (OR 1.86, P = 0.044) and DIEP (OR 1.75, P = 0.004), than expander/implant reconstructions. Failure rates were relatively low, ranging from 0% for PTRAM to 5.9% for expander/implant reconstructions. CONCLUSION: In this multicenter analysis, procedure choice and other patient variables were significant predictors of 1-year complications in breast reconstruction. These findings should be considered in counseling patients on reconstructive options.

Guidelines of care for the management of basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common form of human cancer, with a continually increasing annual incidence in the United States. When diagnosed early, the majority of BCCs are readily treated with office-based therapy, which is highly curative. In these evidence-based guidelines of care, we provide recommendations for the management of patients with BCC, as well as an in-depth review of the best available literature in support of these recommendations. We discuss biopsy techniques for a clinically suspicious lesion and offer recommendations for the histopathologic interpretation of BCC. In the absence of a formal staging system, the best available stratification based on risk for recurrence is reviewed. With regard to treatment, we provide recommendations on treatment modalities along a broad therapeutic spectrum, ranging from topical agents and superficially destructive modalities to surgical techniques and systemic therapy. Finally, we review the available literature and provide recommendations on prevention and the most appropriate follow-up for patients in whom BCC has been diagnosed.

Guidelines of care for the management of cutaneous squamous cell carcinoma.

Cutaneous squamous cell carcinoma (cSCC) is the second most common form of human cancer and has an increasing annual incidence. Although most cSCC is cured with office-based therapy, advanced cSCC poses a significant risk for morbidity, impact on quality of life, and death. This document provides evidence-based recommendations for the management of patients with cSCC. Topics addressed include biopsy techniques and histopathologic assessment, tumor staging, surgical and nonsurgical management, follow-up and prevention of recurrence, and management of advanced disease. The primary focus of these recommendations is on evaluation and management of primary cSCC and localized disease, but where relevant, applicability to recurrent cSCC is noted, as is general information on the management of patients with metastatic disease.

Surgical Duration Impacts Venous Thromboembolism Risk in Microsurgical Breast Reconstruction.

BACKGROUND: Increased surgical duration can impact patient outcomes and operative efficiency metrics. In particular, there are studies suggesting that increased surgical duration can increase the risk of venous thromboembolism (VTE). One of the longer duration plastic surgery procedures commonly performed is microsurgical breast reconstruction. With the widening indications for multiple and "stacked" free flaps to reconstruct breasts, we endeavored to assess (1) the relationship between duration of microsurgical breast reconstruction and VTE; and (2) determine if a threshold operative time exists that connotes VTE higher risk. METHODS: Patients from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) between 2005 and 2014 who underwent microsurgical breast reconstruction were identified by Current Procedural Terminology code. Three models of multivariate logistic regression were used to characterize the adjusted risk for VTE by operative duration, bilaterality, the length of stay, and patient demographics. RESULTS: A total of 4,782 patients who underwent microsurgical breast reconstruction were identified. Overall VTE incidence was 1.13%. The mean operative duration was 8:31 hours:minutes (standard deviation: 2:59). Operative duration was statistically associated with VTE in continuous, quintile, and dichotomized risk models. Beyond an operative duration of 11 hours, adjusted VTE risk increases fourfold corresponding to a number needed to harm of 45.8. CONCLUSIONS: Increasing surgical duration heightens the risk of VTE in microsurgical breast reconstruction. Increasing body mass index and age enhances this VTE risk. Moreover, limiting surgical duration to 11 hours or less can decrease VTE risk by fourfold vis-à-vis baseline. LEVEL OF EVIDENCE: Risk, II.

Demystifying the "July Effect" in Plastic Surgery: A Multi-Institutional Study.

BACKGROUND: The "July Effect" refers to a theoretical increase in complications that may occur with the influx of inexperienced interns and residents at the beginning of each academic year in July. OBJECTIVES: We endeavored to determine if a July Effect occurs in plastic surgery. METHODS: Plastic surgery procedures were isolated from the National Surgical Quality Improvement Program registry. Cases involving residents were grouped as either having occurred within the first academic quarter (AQ1) or remaining year (AQ2-4). Groups were propensity matched using patient/operative factors and procedure type to account for baseline differences. Univariate and multivariate regression analyses assessed differences in overall complications, surgical and medical complications, individual complications, length of hospital stay, and operative time. A comparison group comprised of procedures without resident involvement was also analyzed. RESULTS: There were 5967 cases with resident involvement, 5156 of which successfully matched. Both univariate and multivariate regression analyses revealed no significant differences between AQ1 and AQ2-4 in terms of overall, surgical, medical and individual complications, or length of hospital stay. There was a statistically significant, albeit not clinically significant, increase in operative time by 10 minutes per procedure during AQ1 in comparison to AQ2-4 (P = 0.001). For procedures lacking resident participation, there were no differences between AQ1 and AQ2-4 in terms of these outcomes. CONCLUSIONS: A July Effect was not observed for plastic surgery procedures in our study, conceivably due to enhanced resident oversight and infrastructural safeguards. Patients electing to undergo plastic surgery early in the academic year can be reassured of their safety during this period.

The Effect of Implant Type on Nipple Position Geometry and Aesthetics Following Tissue Expander Reconstruction After Nipple Sparing Mastectomy.

BACKGROUND: While recent studies have reported modest to no difference in breast aesthetics for shaped and round implant types in breast augmentations, the anatomy and biomechanics in the setting of breast reconstruction is different. OBJECTIVES: Accordingly, we endeavored to evaluate whether two implant types impacted nipple position and aesthetic features in prosthetic breast reconstruction. METHODS: A retrospective chart review was carried out on patients who underwent nipple-sparing mastectomy (NSM) with immediate tissue expander breast reconstruction. Patients were divided into two cohorts: smooth round implants and textured shaped implants. Postoperative photographs were evaluated to assess nipple displacement vis-à-vis a vector of maximal projection and aesthetic outcome for features of breast shape. RESULTS: Of 102 breasts meeting the inclusion criteria, 41 had tissue expander-implant reconstruction with anatomical shaped implants, and 61 had reconstruction with smooth round implants. The shaped implant cohort had less nipple deviation from the point of maximal projection (3.69 ± 6.24 vs 7.52 ± 10.50; P < 0.0001). Graded semi-quantitative aesthetic scores were also higher (4.04 ± 0.67 vs 3.72 ± 0.93; P = 0.0044) in the shaped implants than in the round cohort. CONCLUSIONS: Unlike breast augmentation, there is a paucity of overlying breast tissue and larger dissected spaces in prosthetic breast reconstruction. Our analysis suggests that in this setting, textured anatomic implants result in less nipple deviation from the point of maximum projection and improved aesthetic outcomes compared to round implants. When considering implant choice in NSM reconstruction, the manifold risks of shaped textured implants must thus be informed by potential aesthetic benefits with respect to shape and enhanced nipple sensation.

ASDS Guidelines Task Force: Consensus Recommendations Regarding the Safety of Lasers, Dermabrasion, Chemical Peels, Energy Devices, and Skin Surgery During and After Isotretinoin Use.

BACKGROUND: Currently, the isotretinoin (13-cis-retinoic acid) package insert contains language advising the discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. It is common practice to follow this standard because of concerns regarding reports of sporadic adverse events and increased risk of scarring. OBJECTIVE: To develop expert consensus regarding the safety of skin procedures, including resurfacing, energy device treatments, and incisional and excisional procedures, in the setting of concurrent or recent isotretinoin use. MATERIALS AND METHODS: The American Society for Dermatologic Surgery authorized a task force of content experts to review the evidence and provide guidance. First, data were extracted from the literature. This was followed by a clinical question review, a consensus Delphi process, and validation of the results by peer review. RESULTS: The task force concluded that there is insufficient evidence to justify delaying treatment with superficial chemical peels and nonablative lasers, including hair removal lasers and lights, vascular lasers, and nonablative fractional devices for patients currently or recently exposed to isotretinoin. Superficial and focal dermabrasion may also be safe when performed by a well-trained clinician.

Outcomes After Elevation of Serratus Anterior Fascia During Prosthetic Breast Reconstruction.

BACKGROUND: Achieving optimal inferolateral coverage is critical to successful prosthetic breast reconstruction. Serratus anterior fascia (SF) elevation, a promising alternative to muscle flaps and acellular dermis (ADM), has not been rigorously studied. This study evaluates complication rates after mastectomy and immediate tissue expander (TE) coverage using SF, relative to other existing methods of reconstruction. METHODS: Retrospective review of consecutive patients undergoing mastectomy with immediate TE reconstruction over 10 years at 1 institution was performed. Patients with serratus muscle (SM) or SF elevation were analyzed. ADM reconstructions were used for comparative analysis only. Relevant demographic and clinical data were recorded. Complications were categorized by type and end outcome, including nonoperative (no further surgery), operative (surgery except explantation), and explantation. RESULTS: The SM and SF elevation was performed in 375 (487 breasts) and 177 (255 breasts) patients, respectively. Mean follow-up was 43.8 months. The SM and SF patients were demographically similar, but SF had higher intraoperative fill volumes (P < 0.0001) and required fewer postoperative expansions (P < 0.0001). There were no differences in complications between SM and SF patients. Regression analysis, adjusted for several variables, revealed that SF was not an independent risk factor for complications. The ADM- and SF-assisted reconstruction also showed no differences in outcomes. CONCLUSIONS: Our review demonstrates that SF elevation is a safe, feasible alternative for achieving inferolateral coverage during prosthetic breast reconstruction. Furthermore, this technique allows for greater fill volumes and less expansions than SM. As a readily available alternative to muscle flaps and ADM, SF elevation should be considered integral to any prosthetic breast reconstruction algorithm.

Impact of Postoperative Antibiotic Prophylaxis Duration on Surgical Site Infections in Autologous Breast Reconstruction.

BACKGROUND: Although some surgeons prescribe prolonged postoperative antibiotics after autologous breast reconstruction, evidence is lacking to support this practice. We used the Tracking Operations and Outcomes for Plastic Surgeons database to evaluate the association between postoperative antibiotic duration and the rate of surgical site infection (SSI) in autologous breast reconstruction. STUDY DESIGN: The intervention of interest for this study was postoperative duration of antibiotic prophylaxis: either discontinued 24 hours after surgery or continued beyond 24 hours. The primary outcome variable of interest for this study was the presence of SSI within 30 days of autologous breast reconstruction. Cohort characteristics and 30-day outcomes were compared using χ² and Fischer exact tests for categorical variables and Student t tests for continuous variables. Multivariate logistic regression was used to control for confounders. RESULTS: A total of 1036 patients met inclusion criteria for our study. Six hundred fifty-nine patients (63.6%) received antibiotics for 24 hours postoperatively, and 377 patients (36.4%) received antibiotics for greater than 24 hours. The rate of SSI did not differ significantly between patients given antibiotics for only 24 hours and those continued on antibiotics beyond the 24-hour postoperative time period (5.01% vs 2.92%, P = 0.109). Furthermore, antibiotic duration was not predictive of SSI in multivariate regression modeling. CONCLUSIONS: We did not find a statistically significant difference in the rate of SSI in patients who received 24 hours of postoperative antibiotics compared to those that received antibiotics for greater than 24 hours. These findings held for both purely autologous reconstruction as well as latissimus dorsi reconstruction in conjunction with an implant. Thus, our study does not support continuation of postoperative antibiotics beyond 24 hours after autologous breast reconstruction.

Assessing Outcomes and Safety of Inpatient Versus Outpatient Tissue Expander Immediate Breast Reconstruction.

BACKGROUND: With the rising cost of healthcare delivery and bundled payments for episodes of care, there has been impetus to minimize hospitalization and increase utilization of outpatient surgery mechanisms. Given the increase in outpatient mastectomy and immediate tissue expander (TE)-based reconstruction and the paucity of data on its comparative safety to inpatient procedures, we sought to understand the risk for early postoperative complications in an outpatient model compared with more traditional inpatient status using the National Surgical Quality Improvement Program database. METHODS: NSQIP data files from 2005 to 2012 were queried to identify patients undergoing immediate TE-based breast reconstruction after mastectomy. Patients were stratified by whether they received outpatient or inpatient care and then propensity score matched based on preoperative baseline characteristics to produce matched cohorts. Multivariate regression analysis was used to determine whether outpatient versus inpatient status conferred differing risk for 30-days complications. RESULTS: Of the 2014 patients who met criteria, 1:1 propensity matching yielded 634 patients in each of the matched cohorts. Overall complications (5.2 vs. 5.4 %), overall surgical complications (4.3 vs. 3.9 %), overall medical complications (1.3 vs. 2.1 %), and return to the operating room (6.6 vs. 7.3 %) were similar between outpatient and inpatients cohorts (p > .2), respectively. There was a small, but significant increased risk of organ/space SSI in outpatients (1.9 vs. 0.5 %, p = .02) and trend for increased risk for pulmonary embolus (PE) and urinary tract infection (UTI) in inpatients (0.3 vs. 0 %, p = .16; 0.3 vs. 0 %, p = .16). CONCLUSIONS: Our studies suggest that outpatient TE confers similar safety profiles to inpatient TE with regards to 30-day postoperative overall complications, medical and surgical morbidity, and return to the operating room. A slightly increased risk for surgical site infection must be balanced against potential risk for known inpatient-related complications such as UTI and PE.

Assessing safety and outcomes in outpatient versus inpatient thyroidectomy using the NSQIP: a propensity score matched analysis of 16,370 patients.

BACKGROUND: With increasing economic healthcare constraints and an evolving understanding of patient selection criteria and patient safety, outpatient thyroidectomy is now more frequently employed. However, robust statistical analyses evaluating outcomes and safety after outpatient thyroidectomy with matched comparisons to inpatient cohorts are lacking. METHODS: The 2011-2012 NSQIP datasets were queried to identify all patients undergoing thyroidectomy. Inpatient and outpatient procedures cohorts were matched 1:1 using propensity score analysis to assess outcomes. Outcomes of interest included surgical and medical complications, reoperation, mortality, and readmission. Univariate and multivariate analyses were utilized to identify predictors of these events. Relative risk ratios were calculated for adverse events between inpatient and outpatient cohorts. RESULTS: In total, 21,508 patients were identified to have undergone a thyroidectomy in 2011-2012. Inpatients and outpatients were matched 1:1 with respect to preoperative and operative characteristics, leaving 8,185 patients in each treatment arm. After matching, overall 30-day morbidity was rare with only 250 patients (1.53 %) experiencing any perioperative morbidity. 476 patients (2.91 %) were readmitted within 30-days of the operation. Both pre- and post-matching, inpatient thyroidectomy was associated with increased risks of readmission, reoperation, and any complication. CONCLUSIONS: Based on this comprehensive population-based study, outpatient thyroidectomy appears to be at least as safe as inpatient thyroidectomy. However, there are still differences in outcomes between inpatient and outpatient cohorts, despite statistical matching of preoperative and intraoperative variables. Future research needs to be spent identifying these as-of-yet unknown risk factors to resolve this discrepancy.

Longer Operative Time During Benign Laparoscopic and Robotic Hysterectomy Is Associated With Increased 30-Day Perioperative Complications.

STUDY OBJECTIVE: The relationship between operative time and perioperative morbidity has not been fully characterized in gynecology. We aimed to determine the impact of operative time on 30-day perioperative complications after laparoscopic and robotic hysterectomy. DESIGN: Patients undergoing laparoscopic and robotic hysterectomy for benign disease from 2006 to 2011 within the National Surgical Quality Improvement Program (NSQIP) database were identified by Current Procedural Terminology code. Operative times were stratified into 60-minute intervals and complication rates analyzed. Primary outcomes included 30-day overall, medical, and surgical complications. Bivariate analyses using χ(2), Fisher's exact, and one-way analysis of variance tests were performed to compare clinical and procedural characteristics associated with longer operative time and complications. Multivariable logistic regression analyses were then performed to determine the independent association between operative time and perioperative complications. DESIGN CLASSIFICATION: Canadian Task Force classification II-2 (Evidence obtained from well-designed cohort or case-control studies preferably from more than 1 center or research group). SETTING: American College of Surgeons NSQIP. PATIENTS: Patients who underwent laparoscopic or robotic hysterectomy for benign disease from 2006 to 2011 at any institution participating in NSQIP. INTERVENTIONS: None, retrospective database study. MEASUREMENTS AND MAIN RESULTS: Of the 7630 laparoscopic and robotic hysterectomies identified, 399 patients (5.2%) experienced complications, most commonly urinary tract infection (UTI; 2.1%), superficial surgical site infection (1.0%), and blood transfusion (1.0%). Return to the operating room was required in 97 patients (1.3%), and there were 4 deaths, for a mortality rate of .05%. Complications increased steadily with longer operative time. Operative time ≥ 240 minutes was associated with increased overall complications (13.8% vs 4.6%, p < .001), surgical complications (5.4% vs 1.5%, p < .001), medical complications (10.4% vs 3.2%, p < .001), return to the operating room (2.7% vs 1.2%, p = .002), deep venous thrombosis (.5% vs .06%, p = .011), pulmonary embolism (.7% vs .1%, p = .012), and blood transfusion (3.4% vs .8%, p < .001). These associations remained statistically significant after multivariable regression analysis. Based on continuous regression modeling, each additional hour of operative time would be expected to increase odds of overall complications (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.28-1.54; p < .001), medical complications (OR, 1.42; 95% CI, 1.28-1.57; p < .001), surgical complications (OR, 1.32; 95% CI, 1.17-1.49; p < .001), venous thromboembolism (OR, 1.47; 95% CI, 1.12-1.92; p = .005), UTI (OR, 1.20; 95% CI, 1.05-1.36; p = .006), blood transfusion (OR, 1.42; 95% CI, 1.18-1.71; p < .001), and return to the operating room (OR, 1.25; 95% CI, 1.08-1.45; p = .003). CONCLUSION: We demonstrated a direct, independent association between operative time and 30-day complications after laparoscopic and robotic hysterectomy. Future research should aim to further delineate risk factors for prolonged operative time and morbidity in laparoscopic hysterectomy to allow surgeons to maximize preoperative planning and optimize patient selection for minimally invasive hysterectomy.
