Abstract BACKGROUND: Anterior approaches for thoracolumbar corpectomies can have significant morbidity. Spine surgeons have historically performed their own anterior approaches, but recently access surgeons are being used more frequently. OBJECTIVE: To evaluate the morbidity rates of approaches performed by an access surgeon and by an approach-trained spinal neurosurgeon. METHODS: From 2004 to 2008, 46 patients undergoing anterior thoracolumbar corpectomies (levels T2-L5) by the senior author (D.C.) were identified and subdivided into 2 groups based on whether an access surgeon was involved. Nine patients were excluded, leaving 37 patients in the final analysis. Blood loss, operative times, length of hospital stay, complications, and neurological outcomes were evaluated. RESULTS: Eighteen patients had anterior spinal access by an approach-trained spinal neurosurgeon, and 19 patients underwent the approach by an access surgeon. Surgeries performed by the spinal neurosurgeon alone were comparable to those performed by an access surgeon with respect to operative time, days spent in the hospital, blood loss, complication rates, and improvement in neurological function. CONCLUSION: There appears to be no increased morbidity of anterior approaches performed by an approach-trained spinal neurosurgeon compared with approaches performed by an access surgeon in terms of operative time, complication rate, and improvement in neurological function.

Background: Several techniques and devices have been described for circumcision each with its own pros and cons. The objective of this study was to compare the outcome of neonatal circumcision between bone-cutter and plastibell devices at our institution. Methods: This is a randomized trial (unregistered) conducted at the Pediatric Surgical Unit of a tertiary teaching hospital situated in a semi-urban setting, between January 2019 and December 2019. The uncircumcised neonates underwent circumcision by either bone-cutter or plastibell device. Demographic characteristics, operative time, estimated blood loss, and postoperative complications were compared. A p-value of <0.05 was considered significant. Results: The age ranged between 7 days and 30 days with a mean of 15.9±5.5 days. The mean age and weight of both groups were well matched (p >0.05). The operative time in the bone cutter technique was 4.2±0.9 minutes compared to 5.8±1.2 minutes in the plastibell device method (p <0.001). Blood loss was lesser with bone cutter (0.27 ±0.32mls versus 0.51 ±0.44mls in the plastibell device, p <0.001). The complication rates were comparable in both study groups (p =1.000). The overall complication rate was 5.8%. The penile perception score and the Hollander wound evaluation score for bone-cutter were 15.7±0.8 and 5.7±0.84 while in the plastibell device were 15.4±1.1 and 5.4±1.1, respectively (p >0.05). Conclusion: Operative time and blood loss were less with bone cutter compared to plastibell device. However, the complication rate, penile perception score, and Hollander wound evaluation scores were similar.

Background We developed a jejunal and colonic experimental human ischemia-reperfusion (IR) model to study pathophysiological intestinal IR mechanisms and potential new intestinal ischemia biomarkers. Our objective was to evaluate the safety of these IR models by comparing patients undergoing surgery with and without in vivo intestinal IR. Methods A retrospective study was performed comparing complication rates and severity, based on the Clavien-Dindo classification system, in patients undergoing pancreatoduodenectomy with (n = 10) and without (n = 20 matched controls) jejunal IR or colorectal surgery with (n = 10) and without (n = 20 matched controls) colon IR. Secondary outcome parameters were operative time, blood loss, 90-day mortality and length of hospital stay. Results Following pancreatic surgery, 63% of the patients experienced one or more postoperative complications. There was no significant difference in incidence or severity of complications between patients undergoing pancreatic surgery with (70%) or without (60%, P = 0.7) jejunal IR. Following colorectal surgery, 60% of the patients experienced one or more postoperative complication. Complication rate and severity were similar in patients with (50%) and without (65%, P = 0.46) colonic IR. Operative time, amount of blood loss, postoperative C-reactive protein, length of hospital stay or mortality were equal in both intervention and control groups for jejunal and colon IR. Conclusion This study showed that human experimental intestinal IR models are safe in patients undergoing pancreatic or colorectal surgery.

Abstract We searched several databases from the times of their inception to 20 December 2018. Randomized controlled trials and cohort studies that compared percutaneous endoscopic transforaminal discectomy (PETD) with percutaneous endoscopic interlaminar discectomy (PEID) were identified. We used a random-effects model to calculate the relative risks (RRs) of, and standardized mean differences (SMDs) between the two techniques, with 95% confidence intervals (CIs). Twenty-six studies with 3294 patients were included in the final analysis. Compared with PEID, PETD reduced the short-term (SMD −0.68; 95% CI −1.01, −0.34; P=0.000) and long-term (SMD −0.47; 95% CI −0.82, −0.12; P=0.000) visual analog scale scores, blood loss (SMD −4.75; 95% CI −5.80, −3.71; P=0.000), duration of hospital stay (SMD −1.86; 95% CI −2.36, −1.37; P=0.000), and length of incision (SMD −3.93; 95% CI −5.23, −2.62; P=0.000). However, PEID was associated with a lower recurrence rate (P=0.035) and a shorter operative time (P=0.014). PETD and PEID afforded comparable excellent- and good-quality data, long- and short-term Oswestry disability index (ODI) scores, and complication rates. PETD treated lumbar disc herniation (LDH) more effectively than PEID. Although PETD required a longer operative time, PETD was as safe as PEID, and was associated with less blood loss, a shorter hospital stay, and a shorter incision. PETD is the best option for patients with LDH.

Background. Studies of previous cohorts have demonstrated a controversial association between extreme body mass index (BMI) and complication rates following total hip arthroplasty (THA). The purpose of this study was to compare 30-day perioperative complications in underweight (BMI <18.50 kg/m2), normal-weight (BMI 18.50–24.99 kg/m2), overweight (BMI 25.00–29.99 kg/m2), class I obesity (BMI 30.00–34.99 kg/m2), and morbidly obese (BMI ≥35.00 kg/m2) groups. Methods. We performed a cohort study including patients who underwent unilateral primary THA by a single surgeon between January 2010 and December 2015 at our institution. We assessed 30-day complications, operation time, operative blood loss, and length of hospital stay. Results. We identified 1565 primary THAs that were performed in patients with varying BMI levels. Compared with the normal-weight patients, the morbidly obese group had a higher 30-day complication rate (8.9% vs. 2.4%), longer operative time (79 minutes vs. 70 minutes), and more blood loss (376 mL vs. 302 mL). Underweight patients did not present any 30-day complications, and there were no differences among underweight and normal-weight patients regarding complication rates, operative time, or blood loss. The mean length of hospital stay was comparable among the different BMI groups. In the multivariate regression model, higher BMI was not associated with a higher risk of 30-day complications. Independent risk factors for 30-day complications were advanced age, prolonged operative time, and cardiovascular comorbidities. Conclusion. Although increased operative time, blood loss, and perioperative complications were seen in the morbidly obese patients, BMI alone was not an independent risk factor for a higher 30-day complication rate. Therefore, our data suggest clinicians should make elderly patients aware of increased 30-day complications before the procedure, particularly those with cardiovascular comorbidities. Withholding THA solely on the basis of BMI is not justified.

Introduction Diabetes is a common co-morbidity of patients undergoing spinal surgery in the UK but there are no published studies from the UK, particularly with respect to length of hospital stay and complications. The aims of this study were to identify complications and length of hospital stay in patients with diabetes undergoing spinal surgery. Methods Data were collected retrospectively for 111 consecutive patients with diabetes (and 97 age and sex matched control patients, identified using computer records) who underwent spinal surgery between 2004 and 2010 in a single centre. The data collected included operative time, blood loss, details of surgery, Clavien complications and length of hospital stay. Results No significant differences were found by group in operative time, blood loss, instrumentation, use of graft or revision surgery. Overall complication rates were higher in the patients with diabetes than in the controls (28.8% vs 15.5%). The mean hospital stay was significantly longer for patients with diabetes than for control patients (4.6 vs 3.2 days, p<0.001). Conclusions This study identified a significantly higher Clavien grade I complication rate and length of hospital stay in patients with diabetes undergoing spinal surgery than control patients (p=0.02). This has resulted in a predictive model being generated. Of note, no infections were seen in patients with diabetes, suggesting that infection rates in this particular group of patients undergoing spinal surgery might not be as high as considered previously.

Background:Minimally invasive posterior cervical foraminotomy for radicular symptoms has become more prevalent. The reported experience with microscopic tubular assisted posterior cervical laminoforaminotomy (MTPF) for the treatment of radicular pain is lacking. Tubular assisted techniques have been considered to offer significant benefit, over open procedures, in terms of minimizing tissue damage, operative time, blood loss, analgesic requirements and length of hospital stay. We hypothesized that MTPF reduces post-operative analgesic requirements and length of hospital stay over the traditional open laminoforaminotomy, with no difference in complication rates and, secondly, that MTPF is comparable to endoscopic posterior foraminotomy (EPF).Methods:We conducted a retrospective review of 107 patients who underwent posterior cervical laminoforaminotomy for radicular pain between 1999 and 2009. Patient demographics, intra-operative parameters, length of hospitalization, post-operative analgesic use, complications and short-term neurological outcome were compared between groups.Results:Between 1999 and 2009, a total of 107 patients were identified to have undergone a cervical foraminotomy. An open approach was used in 65 patients, while 42 underwent MTPF. Operative time and complications were comparable between groups. Significant differences favoring MTPF were observed in operative blood loss, post-operative analgesic use and length of hospital stay (p<0.001). All results were comparable to previous reports utilizing EPF.Conclusions:MTPF for the treatment of cervical radiculopathy significantly reduces blood loss, post-operative analgesic use and length of hospital stay compared to the standard open approach. Operative time and complication rates were comparable between both techniques, whilst MTPF offered similar results compared to EPF.

OBJECTIVEPosterior-based thoracolumbar 3-column osteotomy (3CO) is a formidable surgical procedure. Surgeon experience and case volume are known factors that influence surgical complication rates, but these factors have not been studied well in cases of adult spinal deformity (ASD). This study examines how surgeon experience affects perioperative complications and operative measures following thoracolumbar 3CO in ASD.METHODSA retrospective study was performed of a consecutive cohort of thoracolumbar ASD patients who underwent 3CO performed by the senior authors from 2006 to 2018. Multivariate analysis was used to assess whether experience (years of experience and/or number of procedures) is associated with perioperative complications, operative duration, and blood loss.RESULTSA total of 362 patients underwent 66 vertebral column resections (VCRs) and 296 pedicle subtraction osteotomies (PSOs). The overall complication rate was 29.4%, and the surgical complication rate was 8.0%. The rate of postoperative neurological deficits was 6.2%. There was a trend toward lower overall complication rates with greater operative years of experience (from 44.4% to 28.0%) (p = 0.115). Years of operative experience was associated with a significantly lower rate of neurological deficits (p = 0.027); the incidence dropped from 22.2% to 4.0%. The mean operative time was 310.7 minutes overall. Both increased years of experience and higher case numbers were significantly associated with shorter operative times (p < 0.001 and p = 0.001, respectively). Only operative years of experience was independently associated with operative times (p < 0.001): 358.3 minutes from 2006 to 2008 to 275.5 minutes in 2018 (82.8 minutes shorter). Over time, there was less deviation and more consistency in operative times, despite the implementation of various interventions to promote fusion and prevent construct failure: utilization of multiple-rod constructs (standard, satellite, and nested rods), bone morphogenetic protein, vertebroplasty, and ligament augmentation. Of note, the use of tranexamic acid did not significantly lower blood loss.CONCLUSIONSSurgeon years of experience, rather than number of 3COs performed, was a significant factor in mitigating neurological complications and improving quality measures following thoracolumbar 3CO for ASD. The 3- to 5-year experience mark was when the senior surgeon overcame a learning curve and was able to minimize neurological complication rates. There was a continuous decrease in operative time as the surgeon’s experience increased; this was in concurrence with the implementation of additional preventative surgical interventions. Ongoing practice changes should be implemented and can be done safely, but it is imperative to self-assess the risks and benefits of those practice changes.

Abstract Purpose New energy-based sutureless vessel ligation devices, such as the Thunderbeat (Olympus Medical Systems Corp., Tokyo, Japan), could reduce operative time and limit blood loss in head and neck surgery; however, efficacy and safety in major head and neck surgery have not been investigated in a prospective, randomized study. Methods This prospective, double-arm, randomized controlled trial consisted of two parts: total laryngectomy (TL) and neck dissection (ND). Thirty patients planned for TL were randomized in two groups. For the ND part, forty-two operative sides were likewise randomized. In both parts, Thunderbeat was used in addition to the standard instrumentation in the intervention groups, while only standard instrumentation was used in the control groups. Primary outcome values were blood loss, operative time and complication rate. Results For the TL part there was no difference in mean blood loss (p = 0.062), operative time (p = 0.512) and complications (p = 0.662) between both hemostatic techniques. For the neck dissection part, there was a reduction in blood loss (mean 210 mL versus 431 mL, p = 0.046) and in operative time (median 101 (IQR 85–130) minutes versus 150 (IQR 130–199) minutes, p = 0.014) when Thunderbeat was used. There was no difference in complication rate between both hemostatic systems (p = 0.261). Conclusion The Thunderbeat hemostatic device significantly reduces operative blood loss and operative time for neck dissections, without increase in complications. In TL, blood loss using Thunderbeat was comparable with the standard technique, but the operative time tended to be shorter.

Objective. To review the existing studies on single-site robotic myomectomy and test the safety and feasibility of this innovative minimally invasive technique. Data Sources. PubMed, Scopus, Google Scholar (from their inception to October 2019), as well as Clinicaltrials.gov databases up to April 2020. Methods of Study Selection. Clinical trials (prospective or retrospective) that reported the outcomes of single-site robotic myomectomy, with a sample of at least 20 patients were considered eligible for the review. Results. The present review was performed in accordance with the guidelines for Systematic Reviews and Meta-Analyses (PRISMA). Four (4) studies met the inclusion criteria, and a total of 267 patients were included with a mean age from 37.1 to 39.1 years and BMI from 21.6 to 29.4 kg/m2. The mean operative time ranged from 131.4 to 154.2 min, the mean docking time from 5.1 to 5.45 min, and the mean blood loss from 57.9 to 182.62 ml. No intraoperative complications were observed, and a conversion rate of 3.8% was reported by a sole study. The overall postoperative complication rate was estimated at 2.2%, and the mean hospital stay ranged from 0.57 to 4.7 days. No significant differences were detected when single-site robotic myomectomy was compared to the multiport technique concerning operative time, blood loss, and total complication rate. Conclusion. Our findings support the safety of single-site robotic myomectomy and its equivalency with the multiport technique on the most studied outcomes. Further studies are needed to conclude on the optimal minimally invasive technique for myomectomy.

Objectives. A prospective study was carried out to compare vaginal hysterectomy (VH) and robotically assisted hysterectomy (RH) for benign gynecological disease.Materials and Methods. All patients who underwent hysterectomy from March 2010 to March 2012 for a benign disease were included. Patients’ demographics per and post surgery results were collected from medical files. A questionnaire was also conducted 2 months after surgery.Results. Sixty patients were included in the RH group and thirty four in the VH one. Operative time was significantly longer in the RH group ( versus  min; ). Blood loss and length of hospital stay were significantly reduced: versus  ml; , and versus days; , respectively. Less pain was reported at D1 and D2 by RH patients, and levels of analgesia were lower compared to those observed in the VH group. No differences were found regarding the rate of conversion to laparotomy, intra- or postoperative complications.Conclusion. Robotically assisted hysterectomy appears to reduce blood loss, postoperative pain, and length of hospital stay, but it is associated with longer operative time and higher cost. Specific indications for RH remain to be defined.
