Effects of Perioperative Inflammatory Response in Cervical Cancer: Laparoscopic versus Open Surgery.

There are few studies between postoperative neutrophil to lymphocyte ratio (NLR) and survival in cervical cancer. We compared postoperative changes in NLR according to surgical methods and analyzed the effect of these changes on 5-year mortality of cervical cancer patients. A total of 929 patients were assigned to either the laparoscopic radical hysterectomy (LRH) (n = 721) or open radical hysterectomy (ORH) (n = 208) group. Propensity score matching analysis compared the postoperative NLR changes between the two groups, and multivariate logistic regression analysis evaluated the association between NLR changes and 5-year mortality. Surgical outcomes between the two groups were also compared. In the LRH group, NLR changes at postoperative day (POD) 0 and POD 1 were significantly lower than in the ORH group after matching (NLR change at POD 0, 10.4 vs. 14.3, p < 0.001; NLR change at POD 1, 3.5 vs. 5.4, p < 0.001). In multivariate logistic regression analysis, postoperative NLR change was not associated with 5-year mortality (2nd quartile: OR 1.55, 95% CI 0.56–4.29, p = 0.401; 3rd quartile: OR 0.90, 95% CI 0.29–2.82, p = 0.869; 4th quartile: OR 1.40, 95% CI 0.48–3.61, p = 0.598), whereas preoperative NLR was associated with 5-year mortality (OR 1.23, 95% CI 1.06–1.43, p = 0.005). After matching, there were no significant differences in surgical outcomes between the two groups. There were significantly fewer postoperative changes of NLR in the LRH group. However, the extent of these NLR changes was not associated with 5-year mortality. By contrast, preoperative NLR was associated with 5-year mortality.

Image-guided Localization Techniques for Nonpalpable Breast Lesions: An Opportunity for Multidisciplinary Patient-centered Care.

Selection of a localization method for nonpalpable breast lesions offers an opportunity for institutions to seek multidisciplinary input to promote value-based, patient-centered care. The diverse range of nonpalpable breast and axillary pathologies identified through increased utilization of screening mammography often necessitates image-guided preoperative localization for accurate lesion identification and excision. Preoperative localization techniques for breast and axillary lesions have evolved to include both wire and nonwire methods, the latter of which include radioactive seeds, radar reflectors, magnetic seeds, and radiofrequency identification tag localizers. There are no statistically significant differences in surgical outcomes when comparing wire and nonwire localization devices. Factors to consider during selection and adoption of image-guided localization systems include physician preference and ease of use, workflow efficiency, and patient satisfaction.

Female Sex Is Associated With Early Morbidity and Mortality but Similar Midterm Survival in Branched/Fenestrated Endovascular Aortic Aneurysm Repair

The objective of this study was to identify sex-related differences in surgical outcomes in patients undergoing branched and/or fenestrated endovascular aortic repair (B/FEVAR) for thoracoabodominal (TAAA) and juxtarenal (JRAA) aortic aneurysms.

Multimodal Analgesia in Head and Neck Free Flap Reconstruction: A Systematic Review.

Postoperative pain after head and neck cancer surgery is commonly treated with opioids, which are associated with considerable side effects. The objective of this study is to analyze the safety and efficacy of using multimodal analgesia (MMA) for patients undergoing head and neck cancer surgery with free flap reconstruction. A systematic search was conducted in PubMed, Cochrane, Embase, Scopus, and clinicaltrials.gov. All studies comparing patients receiving MMA (gabapentin, corticosteroids, local anesthetic, acetaminophen, nonsteroidal anti-inflammatory drugs [NSAIDs]) vs patients receiving opioids for head and neck cancer surgery with free flap reconstruction were screened. The primary outcome was postoperative opioid usage. Secondary outcomes included length of stay, subjective pain scores, surgical/medical complications, adverse effects, and 30-day outcomes. A total of 10 studies representing 1253 patients (MMA, n = 594; non-MMA, n = 659) met inclusion criteria. Gabapentinoids were the most commonly used intervention (72.9%) followed by NSAIDs (44.6%), acetaminophen (44.3%), corticosteroids (25.1%), ketamine (7.2%), and nerve block (3.4%). Eight studies reported a significant decrease in postoperative opioid usage in the MMA groups. Subjective pain had wider variation, with most studies citing significant pain improvement. There were no differences in surgical outcomes, medical complications, adverse effects, or 30-day mortality and readmission rates. With the rise of the opioid epidemic, MMA may play an important role in the treatment of postoperative pain after head and neck cancer surgery. A growing body of literature demonstrates a variety of effective perioperative regimens.

The patient characteristics of esophageal carcinoma following laparoscopic myotomy for esophageal achalasia.

It is common knowledge that esophageal achalasia patients have a high risk of developing esophageal carcinoma. The present study assessed the characteristics of esophageal carcinoma patients following laparoscopic Heller-Dor surgery (LHD) for esophageal achalasia. Among 622 cases which were esophageal achalasia patients and underwent LHD as the primary surgery, we compared the patient background, pathophysiology, symptoms, and surgical outcomes according to whether or not esophageal carcinoma occurred following surgery. Six cases (0.96%) of postoperative esophageal carcinoma were confirmed. The characteristics of the cases in which esophageal carcinoma occurred were older age, longer disease duration (p = 0.0362 and 0.0028, respectively), decreased sphincter pressure of the lower esophagus, a high rate of sigmoid esophagus, and a long esophagus lateral diameter (p = 0.0214, 0.001, and 0.0416, respectively). Moreover, no differences in surgical outcomes were confirmed and there were no differences in symptoms from before and following surgery. The characteristics of esophageal carcinoma patients with achalasia following laparoscopic myotomy were an older age, longer disease duration, and greater progression of disease pathophysiology.

Review of Variables Associated With Positive Surgical Margins Using Scout Reflector Localizations for Breast Conservation Therapy

ObjectiveTo evaluate factors contributing to positive surgical margins associated with reflector guidance for patients undergoing breast conserving therapy for malignancy. Materials and MethodsA retrospective IRB-approved review of our institutional database was performed for malignant breast lesions preoperatively localized from January 1, 2018 to December 31, 2020. The following data was recorded using electronic medical records: lesion type and grade, lesion location, reflector and wire placement modality, use of intraoperative ultrasound, margin status, patient age, family history, BMI, and final pathology. Statistical analysis was performed with univariate summary statistics and logistic regression. P < .05 was significant. ResultsA total of 606 image-guided pre-surgical localizations were performed for lumpectomies of breast malignancies. A total of 352 of 606 (58%) wire localizations and 254 of 606 (42%) SCOUT reflector localizations were performed. Sixty out of 352 (17%) of wire-localized patients had positive surgical margins, whereas forty-eight out of 254 (19%) of reflector-localized patients had positive surgical margins. (OR = 1.12, P value: .59). For reflector guided cases, the use of intraoperative ultrasound (IOUS) was associated with decreased positive margin status (OR = 0 .28, 95% CI = [0.14, 0.58]) while in situ disease was associated with increased positive margin status (OR = 1.99, 95% CI = [1.05, 3.75]). No association between modality used for localization (mammography vs. ultrasound) and positive margin status was observed (OR = 0.63, 95% CI = [0.33, 1.19]). No association between positive margins and age, family history, tumor location and BMI was observed. ConclusionFor reflector guided surgeries, the use of IOUS was associated with decreased positive margins, by contrast the presence of ductal carcinoma in situ was associated with increased positive margins. There was no statistically significant difference in surgical outcomes for reflector-guided localization compared to wire localizations of the breast.

Clinical Outcomes between Stand-Alone Zero-Profile Spacers and Cervical Plate with Cage Fixation for Anterior Cervical Discectomy and Fusion: A Retrospective Analysis of 166 Patients.

Stand-alone (SA) zero-profile implants are an alternative to cervical plating (CP) in anterior cervical discectomy and fusion (ACDF). In this study, we investigate differences in surgical outcomes between SA and CP in ACDF. We conducted a retrospective analysis of 166 patients with myelopathy and/or radiculopathy who had ACDF with SA or CP from Jan 2013–Dec 2016. We measured surgical outcomes including Bazaz dysphagia score at 3 months, Nurick grade at last follow-up, and length of hospital stay. 166 patients (92F/74M) were reviewed. 92 presented with radiculopathy (55%), 37 with myelopathy (22%), and 37 with myeloradiculopathy (22%). The average operative time with CP was longer than SA (194 ± 69 vs. 126 ± 46 min) (p < 0.001), as was the average length of hospital stay (2.1 ± 2 vs. 1.5 ± 1 days) (p = 0.006). At 3 months, 82 patients (49.4%) had a follow-up for dysphagia, with 3 patients reporting mild dysphagia and none reporting moderate or severe dysphagia. Nurick grade at last follow-up for the myelopathy and myeloradiculopathy cohorts improved in 63 patients (85%). Prolonged length of stay was associated with reduced odds of having an optimal outcome by 0.50 (CI = 0.35–0.85, p = 0.003). Overall, we demonstrate that there is no significant difference in neurological outcome or rates of dysphagia between SA and CP, and that both lead to overall improvement of symptoms based on Nurick grading. However, we also show that the SA group has shorter length of hospital stay and operative time compared to CP.

Effect of abdominal binder after laparoscopic cholecystectomy on enhanced recovery: a randomized controlled trial.

PurposeThe purpose of this randomized controlled trial was to compare the effects of abdominal binder after laparoscopic cholecystectomy.MethodsFrom August to December 2020, 66 patients who were set to undergo cholecystectomy were selected for a prospective trial at Kangbuk Samsung Hospital, Seoul, Republic of Korea, and their clinical characteristics and postoperative surgical outcomes were evaluated. Among 66 patients, 33 patients belong to the abdominal binder group and the other 33 patients belong to the control group.ResultsThe average hospital stay was 2.46 ± 1.29 days, and was not significantly different between the two groups. The average postoperative pain score (visual analogue scale, 0–10) 12, 24, and 48 hours after surgery were not significantly different. However, the degree of comfort score was significantly higher for the control group patients (2.56 vs. 3.33, p < 0.001). Time to the first ambulation, walking ability, return of bowel function, time to full diet resumption, and the numbers of analgesics and antiemetics administered were not significantly different between the two groups.ConclusionNo postoperative recovery benefit and no reduction in hospital stay was found in patients who used an abdominal binder while undergoing laparoscopic cholecystectomy. Statistically, between the group that used the binder and the one that did not, no significant differences in surgical outcome nor postoperative outcome were observed. The only exception was that the degree of comfort score was significantly higher in the control group. Therefore, in terms of patient benefit and convenience, wearing an abdominal binder after laparoscopic cholecystectomy is not recommended.

Differences in Surgical Outcome in Near Total Thyroidectomy for Benign Nodular Goiter: A Comparison of LigaSure Vessel Sealer versus Conventional Clamp Knot Tie Technique

Objective: To compare the efficacy of LigaSure Vessel Sealer in Near Total Thyroidectomy versus Conventional Clamp Knot Tie Technique in terms of bleeding, operative time and postoperative drainage.&#x0D; Methodology: This comparative cross sectional study was conducted at Department of Surgery, Liaquat University of Medical and Health Sciences, Jamshoro. Study duration was one year from November 2019 to October 2020. All patients of any age with benign multinodular goiter and either of gender were included. The study subjects were grouped into two categories by randomization (odd / even). The odd numbers were given to patients operated for ligasure and even numbers were given to patients operated with conventional clamp knot tie technique. Outcomes were observed with respect to post-operative calcium level, intra-operative bleeding, operative time, post-operative pain &amp; post-operative hospital stay. All the data was recorded via study proforma. Data was analyzed by using SPSS version 20.&#x0D; Results: Total 55 patients were observed. Mean age was 33.25±10.60 years in clamp knot tie procedure group and 35.16±07.96 years in ligasure technique group; without significant difference (p-0.448). Pre and post-operative calcium levels were statistically insignificant among both groups (p-0.358 and 0.163), while loss of blood, hospital stay, post-operative pain and operative duration were significantly greater in clamp knot tie technique group in comparison to ligasure technique group (p-&lt;0.001).&#x0D; Conclusion: LigaSure Vessel Sealer is a feasible and reliable surgical technique and significantly more effective as compared to conventional clamp knot tie technique in terms of post-operative bleeding, operative time, post-operative pain and post-operative hospital stay. However, calcium level was statistically insignificant.

Differences in surgical outcome after anterior corpectomy and reconstruction with an expandable cage with rectangular footplates between thoracolumbar and lumbar osteoporotic vertebral fracture

BackgroundAnterior and posterior spinal fixation (APSF) can provide rigid structural anterior column support in patients with osteoporotic vertebral fracture (OVF). A new rectangular footplate designed based on biomechanical studies of endplates provides better resistance to subsidence. However, differences in characteristics exist between the thoracolumbar and lower lumbar spine. The purpose of this study was to evaluate the surgical outcomes following APSF using an expandable cage with rectangular footplates in the thoracolumbar/lumbar region. MethodsConsecutive patients who underwent APSF for OVF at multiple centers were retrospectively reviewed. Clinical and radiographic evaluations were performed by dividing the patients into thoracolumbar (TL, T10–L2) and lumbar (L, L3–L5) groups. Surgical indications were incomplete neurologic deficit or intractable back pain with segmental spinal instability. Surgical outcomes including the Japanese Orthopaedic Association (JOA) score and reoperation rate were compared between TL and L groups. ResultsSixty-nine patients were followed-up for more than 12 months and analyzed. Operative intervention was required for 35 patients in the TL group and 34 patients in the L group. Mean ages in the TL and L groups were 76.5 years and 75.1 years, respectively. Intra-vertebral instability was more frequent in the TL group (p<0.001). Screw fixation range was significantly longer in the TL group (p=0.012). The rate of cage subsidence did not differ significantly between the TL group (46%) and L group (44%). Reoperation rate tended to be higher in the TL group (p=0.095). Improvement ratio of JOA score was significantly better in the L group (60%) than in the TL group (46.9%, p=0.029). ConclusionAPSF using an expandable cage was effective to treat OVF at both lumbar and thoracolumbar levels. However, the improvement ratio of the JOA score was better in the L group than in the TL group.

Surgical outcomes and rate of pathological response in resectable/borderline resectable pancreatic cancer patients undergoing neoadjuvant gemcitabine/nab-paclitaxel versus FOLFIRINOX: A retrospective institutional analysis.

e16247 Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal solid tumors, predicted to become the second leading cause of cancer related death in some regions of the world. It often presents at an advanced stage, which contributes to poor five-year survival rates of 2%-9%, ranking firmly last amongst all cancer sites in terms of prognostic outcomes for patients. Only about 20% of the cases are diagnosed early enough to undergo surgical resection leading to complete remission. While chemotherapy has an established role in the setting of metastatic disease, utilizing it in the neo-adjuvant setting has been adopted by most institutes for resectable/ borderline resectable cases. Ongoing trials are exploring the use of different regimens in the neo-adjuvant setting. The aim of our study was to identify patients with resectable/borderline resectable PDAC undergoing neoadjuvant chemotherapy and differences in surgical outcome based on the regimen received i.e gemcitabine/ nab-Paclitaxel vs FOLFIRINOX. Methods: A retrospective review was conducted of all patients diagnosed with PDAC from 2017-2019 at Allegheny General Hospital. Data analysis was completed using IBM SPSS v23. Summary statistics were presented using percentages for categorical variables and medians with interquartile ranges for continuous variables. Results: Out of 121 patients who received and completed treatment in our institution, 30 underwent neoadjuvant chemotherapy treatment followed by surgical intervention. 21 (70%) patients were found to be borderline resectable, 8 (27%) patients were resectable and 1 patient had locally advanced PDAC. 16 (53%) patients received FOLFIRINOX compared to 13 (43%) patients received gem/nab-paclitaxel. Among patients who received neoadjuvant FOLFIRINOX, 5 out of 16 (31%) patients had moderate to significant treatment response at the time of surgery compared to 7 out of 13 (54%) patients who received gemcitabine/nab-paclitaxel. Conclusions: Our study revealed no significant difference (p=0.21) between the patients who received neoadjuvant gemcitabine/nab-paclitaxel vs FOLFIRINOX in terms of treatment response assessed pathologically at the time surgical resection. We recognize the limitations of our study in terms of it being a retrospective analysis with a small sample size and therefore further prospective and randomized controlled trials are needed to determine the most suitable and effective regimen in the neoadjuvant setting for resectable/borderline resectable PDAC patients. Response to treatment among different chemotherapy groups.[Table: see text]

Subxifoid versus transthoracic thoracoscopic lobectomy: Results of a retrospective analysis before and after matching analysis.

BackgroundHere, we report our initial experience with subxifoid video‐assisted thoracoscopic surgery (SVATS) lobectomy for the management of primary lung cancer, and compared the outcomes of SVATS with those of conventional transthoracic VATS (CVATS) lobectomies to validate its feasibility and usefulness.MethodsThe clinical data of consecutive patients undergoing VATS lobectomy via SVATS or CVATS for lung cancer were retrospectively compared. The endpoints were to evaluate the statistical differences in surgical results, postoperative pain (measured with visual analog scale [VAS] scores at 8 hours, Day 1, Day 2, Day 3, at discharge, one month and three months after surgery) and paresthesia (measured at one‐ month, and three months after surgery). The two groups were compared before and after matching analysis.ResultsOur study population included 223 patients: 84 in the SVATS and 139 in the CVATS group. The two groups were not comparable for sex (P = 0.001), preoperative comorbidity as cardiopathy (P = 0.007), BMI value (P = 0.003), left‐sided procedure (P = 0.04), tumor stage (P = 0.04), and tumor size (P = 0.002). These differences were overcome by propensity score matching (PSM) analysis that yielded two well‐matched groups which included 61 patients in each group. Surgical outcomes including blood loss, hospital stay and complications were similar before and after matching analysis, but SVATS compared to CVATS was associated with longer operative time before (159 ± 13 vs. 126 ± 6.3, P < 0.0001), and after matching analysis (161 ± 23 vs. 119 ± 8.3; P < 0.0001) and significant reduction of postoperative pain during the different time‐points (P < 0.001), and paresthesia at one (P = 0.001), and three months (P < 0.0001).ConclusionsSVATS lobectomy is a feasible and safe strategy with surgical outcomes similar to CVATS lobectomy but with less postoperative pain and paresthesia.Key pointsSignificant findings of the study Subxifoid thoracoscopic lobectomy is a feasible and safe procedure, with potential benefits in terms of postoperative pain and paresthesia compared to conventional thoracoscopic lobectomyOur results showed that surgical outcomes including blood loss, hospital stay, morbidity and mortality are similar but subxifoid thoracoscopy was associated with significant reduction of postoperative pain and paresthesia. What this study adds Subxifoid thoracoscopy is a safe procedure; compared to conventional transthoracic thoracoscopy, it avoids intercostal incisions, and spares nerve trauma, resulting in a reduction of postoperative pain and paresthesia.

Difference in surgical outcomes of rectal cancer by study design: meta-analyses of randomized clinical trials, case-matched studies, and cohort studies.

BackgroundRCTs are considered the standard in surgical research, whereas case-matched studies and propensity score matching studies are conducted as an alternative option. Both study designs have been used to investigate the potential superiority of robotic surgery over laparoscopic surgery for rectal cancer. However, no conclusion has been reached regarding whether there are differences in findings according to study design. This study aimed to examine similarities and differences in findings relating to robotic surgery for rectal cancer by study design.MethodsA comprehensive literature search was conducted using PubMed, Scopus, and Cochrane CENTRAL to identify RCTs, case-matched studies, and cohort studies that compared robotic versus laparoscopic surgery for rectal cancer. Primary outcomes were incidence of postoperative overall complications, incidence of anastomotic leakage, and postoperative mortality. Meta-analyses were performed for each study design using a random-effects model.ResultsFifty-nine articles were identified and reviewed. No differences were observed in incidence of anastomotic leakage, mortality, rate of positive circumferential resection margins, conversion rate, and duration of operation by study design. With respect to the incidence of postoperative overall complications and duration of hospital stay, the superiority of robotic surgery was most evident in cohort studies (risk ratio (RR) 0.83, 95 per cent c.i. 0.74 to 0.92, P < 0.001; mean difference (MD) –1.11 (95 per cent c.i. –1.86 to –0.36) days, P = 0.004; respectively), and least evident in RCTs (RR 1.12, 0.91 to 1.38, P = 0.27; MD –0.28 (–1.44 to 0.88) days, P = 0.64; respectively).ConclusionResults of case-matched studies were often similar to those of RCTs in terms of outcomes of robotic surgery for rectal cancer. However, case-matched studies occasionally overestimated the effects of interventions compared with RCTs.

Outcomes of Alternative Reservoir Placement in the Lateral Retroperitoneum During Inflatable Penile Prosthesis Placement

To describe outcomes of reservoir placement, exchange, and extraction from the lateral retroperitoneum (LR) in complex patients with a three-piece inflatable penile prosthesis (IPP). A retrospective chart review was performed on all patients that underwent placement of an IPP from 2009 to 2019. Patients with placement of the reservoir in the LR were identified. Intraoperative complications during reservoir placement, exchange, or removal, reservoir-related outcomes, and secondary device-related outcomes were collated and compared to patients who underwent traditional Space of Retzius reservoir placement. A total of 587 men underwent primary IPP placement with 321 patients undergoing reservoir placement in the SOR and 266 in the LR. No significant differences were found in intra-operative reservoir-related outcomes (P=.272) between the 2 groups during placement, replacement, or extraction. Bowel injury occurred in 1 patient in the LR group during placement. No significant differences were found in postoperative reservoir complications (P= .534). Both groups each had one instance of patient reported bulge and pain at reservoir site (P= .6777). Two (0.6%) patients in the SOR group and 3 (1.1%) patients in the LR group had a reservoir failure or leak. There was a trend towards a lower rate of device infections in the LR group (1.9%) compared to the SOR group (4.7%) (P= .063). There were no significant differences in overall device mechanical failure rates between both groups (P= .919). Reservoir placement in the LR is safe in patients with complex pelvic anatomy with equivalent device durability and no difference in surgical outcomes compared to standard retropubic reservoir placement.

Mild to Moderate Varus Alignment in Relation to Surgical Repair of a Medial Meniscus Root Tear: A Matched-Cohort Controlled Study With 2 Years of Follow-up

Background: Increased varus alignment of the lower extremity is known to be a poor prognostic factor for the surgical repair for a medial meniscus root tear (MMRT). However, given the concept of constitutional varus, which is present in a substantial portion of the normal population, the generally accepted surgical indication for MMRT concerning a varus alignment of 5° may be unnecessarily narrow. Purpose: To compare the surgical outcomes of arthroscopic transtibial pullout repair of MMRT according to the degree of varus alignment of the lower extremity. Study Design: Cohort study; Level of evidence, 3 Methods: Patients who underwent isolated arthroscopic transtibial pullout repair of MMRT between January 2010 and July 2017 at one institution and had a minimum follow-up of 2 years were included in this study. Patients were classified into 1 of 2 groups: the experimental group (n = 22) included patients with a preoperative hip-knee-ankle angle between 5° and 10° varus (mild to moderate varus alignment) and the control group (n = 51) included those with a preoperative hip-knee-ankle angle <5° varus (neutral alignment). Clinical scores and radiographic parameters were compared between the groups to assess surgical outcomes, which were statistically matched for potential confounders (age, body mass index, the severity of cartilage lesion) by use of the inverse probability of treatment weighting. A noninferiority trial was performed comparing the experimental and control groups in terms of subjective outcomes (International Knee Documentation Committee subjective and Lysholm scores) and objective outcomes (postoperative medial meniscal extrusion and the rate of osteoarthritis progression). Results: There were no statistically significant differences in surgical outcomes between the groups in subjective and objective aspects, which were consistent before and after inverse probability of treatment weighting. Apart from the clinical improvement observed in both groups, overall degenerative changes in the knee were found, although progression rates did not differ between the groups. In terms of the noninferiority trial, the overall surgical outcomes in the experimental group were not inferior to those in the control group. Conclusion: The short-term surgical outcomes of arthroscopic transtibial pullout repair for MMRT of patients with mild to moderate varus alignment were not inferior to but rather comparable with those with neutral alignment in terms of subjective and objective aspects. Therefore, it would be inappropriate to exclude patients with a diagnosis of MMRT from being indicated for the surgery simply because of mild to moderate varus alignment.

Differences in surgical outcome between petroclival meningioma and anterior petrous meningioma.

Petroclival meningiomas (PC MNGs) and anterior petrous meningiomas (AP MNGs) have similar locations. However, these are different tumors clearly divided by the trigeminal nerve. There has never been a study on the comparison of the surgical outcomes of these two meningiomas. In this study, we compared and analyzed the surgical outcome of PC MNGs and AP MNGs. The charts of 85 patients diagnosed with PC MNGs of AP MNGs who underwent surgical treatment were retrospectively reviewed. And we analyzed the characteristics of 49 PC MNGs (57.6%) and compared them with those of 36 AP MNGs. Preoperative brainstem edema was observed in 11 patients (22.4%) of the PC MNG group and 1 patient (2.8%) of the AP MNG group (p = 0.024). Total tumor removal was achieved in 21 patients (58.3%) of the AP MNG group, but only 17 patients (34.7%) of the PC MNG group were able to completely (p = 0.047). In addition, sixth cranial nerve palsy occurred in 17 patients (34.7%) of the PC MNG group and 4 patients (11.1%) of the AP MNG group (p = 0.025). In this study, we found that PC MNGs has a worse surgical outcome than AP MNGs, because PC MNGs were difficult to completely remove and were more likely to damage abducens nerve.

Kidney-Pancreas Transplant Recipients Experience Higher Risk of Complications Compared to the General Population after Undergoing Coronary Artery Bypass Grafting.

This retrospective analysis aims to identify differences in surgical outcomes between pancreas and/or kidney transplant recipients compared with the general population undergoing coronary artery bypass grafting (CABG). Using Nationwide Inpatient Sample (NIS) data from 2005 to 2014, patients who underwent CABG were stratified by either no history of transplant, or history of pancreas and/or kidney transplant. Multivariate analysis was used to calculate odds ratio (OR) to evaluate in-hospital mortality, morbidity, length of stay (LOS), and total hospital charge in all centers. The analysis was performed for both nonemergency and emergency CABG. Overall, 2,678 KTx (kidney transplant alone), 184 PTx (pancreas transplant alone), 254 KPTx (kidney-pancreas transplant recipients), and 1,796,186 Non-Tx (nontransplant) met inclusion criteria. KPTx experienced higher complication rates compared with Non-Tx (78.3 vs. 47.8%, p < 0.01). Those with PTx incurred greater total hospital charge and LOS. On weighted multivariate analysis, KPTx was associated with an increased risk for developing any complication following CABG (OR 3.512, p < 0.01) and emergency CABG (3.707, p < 0.01). This risk was even higher at transplant centers (CABG OR 4.302, p < 0.01; emergency CABG OR 10.072, p < 0.001). KTx was associated with increased in-hospital mortality following emergency CABG, while PTx and KPTx had no mortality to analyze. KPTx experienced a significantly higher risk of complications compared with the general population after undergoing CABG, in both transplant and nontransplant centers. These outcomes should be considered when providing perioperative care.

Minimally invasive hysterectomy for endometriosis: Surgical outcomes based on surgeon specialty

Introduction: To evaluate differences in surgical outcomes of minimally invasive hysterectomy performed for endometriosis between general gynecologists and gynecologic oncologists. Methods: Utilizing the 2016–2018 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) hysterectomy dataset, we evaluated baseline characteristics and surgical outcomes for patients who underwent a minimally invasive hysterectomy for endometriosis between general gynecology and gynecologic oncology groups. Results: From 2016 to 2018, a total of 3751 minimally invasive hysterectomies were performed for the primary diagnosis of endometriosis. Of these cases, 3129 (83.4%) were performed by general gynecologists and 622 (16.6%) by gynecologic oncologists. There were several differences in baseline characteristics between the groups. Notably, general gynecologists performed a higher proportion of vaginal hysterectomies (7.9% vs 0.6%, p &lt; 0.01). There were no statistically significant differences in overall 30-day complications or mortality between general gynecology and oncology groups, with the exception of a higher rate of postoperative sepsis (0.8% vs 0.2%, p = 0.01) in hysterectomies performed by oncologists. Compared to general gynecologists, oncologists had a longer operative time (134.9 ± 65.4 min vs 129 ± 60.9 min, p = 0.05). Multivariate regression of multiple tracked and composite outcomes revealed no consistent confounding variables other than race. In fact, African American race was a statistically significant predictive factor of composite complications (OR 1.80, p &lt; 0.01), morbidity (OR 1.84, p &lt; 0.05), and unplanned readmission (OR 2.30, p &lt; 0.01). Surgeon specialty was not associated with composite complications, hysterectomy-specific complications, or readmission. Conclusion: There are no significant differences in surgical outcomes for minimally invasive hysterectomy for endometriosis between these two surgical subspecialties.

The Role of Hyperthermic Intraperitoneal Chemotherapy in Pseudomyxoma Peritonei After Cytoreductive Surgery

Studies on the prognostic role of hyperthermic intraperitoneal chemotherapy (HIPEC) in pseudomyxoma peritonei (PMP) are currently not available. To evaluate outcomes after cytoreductive surgery (CRS) and HIPEC compared with CRS alone in patients with PMP. This cohort study analyzed data from the Peritoneal Surface Oncology Group International (PSOGI) registry, including 1924 patients with histologically confirmed PMP due to an appendiceal mucinous neoplasm. Eligible patients were treated with CRS with or without HIPEC from February 1, 1993, to December 31, 2017, and had complete information on the main prognostic factors and intraperitoneal treatments. Inverse probability treatment weights based on the propensity score for HIPEC treatment containing the main prognostic factors were applied to all models to balance comparisons between the CRS-HIPEC vs CRS-alone groups in the entire series and in the following subsets: optimal cytoreduction, suboptimal cytoreduction, high- and low-grade histologic findings, and different HIPEC drug regimens. Data were analyzed from March 1 to June 1, 2018. HIPEC including oxaliplatin plus combined fluorouracil-leucovorin, cisplatin plus mitomycin, mitomycin, and other oxaliplatin-based regimens. Overall survival, severe morbidity (determined using the National Cancer Institute Common Terminology for Adverse Events, version 3.0), return to operating room, and 30- and 90-day mortality. Differences in overall survival were compared using weighted Kaplan-Meier curves, log-rank tests, and Cox proportional hazards multivariable models. A sensitivity analysis was based on the E-value from the results of the main Cox proportional hazards model. Differences in surgical outcomes were compared using weighted multivariable logistic models. Of the 1924 patients included in the analysis (997 [51.8%] men; median age, 56 [interquartile range extremes (IQRE), 45-65] years), 376 were in the CRS-alone group and 1548 in the CRS-HIPEC group. Patients with CRS alone were older (median age, 60 [IQRE, 48-70] vs 54 [IQRE, 44-63] years), had less lymph node involvement (14 [3.7%] vs 119 [7.7%]), received more preoperative systemic chemotherapy (198 [52.7%] vs 529 [34.2%]), and had higher proportions of high-grade disease (179 [47.6%] vs 492 [31.8%]) and suboptimal cytoreduction residual disease (grade 3, 175 [46.5%] vs 117 [7.6%]). HIPEC was not associated with a higher risk of worse surgical outcomes except with mitomycin, with higher odds of morbidity (1.99; 95% CI, 1.25-3.19; P = .004). HIPEC was associated with a significantly better overall survival in all subsets (adjusted hazard ratios [HRs], 0.60-0.68, with 95% CIs not crossing 1.00). The weighted 5-year overall survival was 57.8% (95% CI, 50.8%-65.7%) vs 46.2% (95% CI, 40.3%-52.8%) for CRS-HIPEC and CRS alone, respectively (weighted HR, 0.65; 95% CI, 0.50-0.83; P < .001; E-value, 2.03). Such prognostic advantage was associated with oxaliplatin plus fluorouracil-leucovorin (HR, 0.42; 95% CI, 0.19-0.93; P = .03) and cisplatin plus mitomycin (HR, 0.57; 95% CI, 0.42-0.78; P = .001) schedules. In this cohort study, HIPEC was associated with better overall survival when performed after CRS in PMP, generally without adverse effects on surgical outcomes.

Gender as a Predictor of Complications in Endoscopic Sinus Surgery.

Understanding patient-specific risk factors for complications of functional endoscopic sinus surgery (ESS) is critical. Previous work has investigated such risk factors, but a population-based analysis has not been performed to date. This study analyzes the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database to identify patient-specific risk factors associated with complications following ESS. A retrospective cohort study of patients who underwent ESS was conducted using the NSQIP database from 2011 to 2017. Patients were identified using CPT-codes for ESS procedures. The primary outcome analyzed was any postoperative complication. Simultaneous procedures with ESS were controlled for with regression analysis. Post-operative complications and 30-day readmission were evaluated using multivariate logistic regression controlling for age, gender, race, comorbidities (diabetes mellitus, hypertension, chronic obstructive pulmonary disease, congestive heart failure, renal failure, steroid use, and cancer history), smoking history, and intraoperative factors. A total of 1279 patients who underwent ESS were identified. The average age of patients was 46.1 (SD = 16.8). Most patients (58.2%) had no major comorbidities. 594 (46.4%) patients had a tonsillectomy, adenoidectomy, or uvulopharyngoplasty at the same time as ESS. 101 (7.9%) patients experienced a complication post-operatively. 46 (3.6%) patients experienced a readmission postoperatively. The most common complication was reoperation (N = 40, 3.1%). Regression analysis revealed that gender was the only demographic factor associated with risk of post-operative complications, with women having a significantly lower risk than men (OR = 0.61, 95% CI 0.37-0.99, P = .046). ESS is typically performed on a relatively young and healthy population. Women have a significantly lower risk of complications after controlling for comorbidities. Further analysis of gender-specific differences in surgical outcomes should be evaluated to understand this phenomenon.
