OBJECTIVEMany options exist for the surgical management of adult spinal deformity. Radiculopathy and lumbosacral pain from the fractional curve (FC), typically from L4 to S1, is frequently a reason for scoliosis patients to pursue surgical intervention. The purpose of this study was to evaluate the outcomes of limited fusion of the FC only versus treatment of the entire deformity with long fusions.METHODSAll adult scoliosis patients treated at the authors’ institution in the period from 2006 to 2016 were retrospectively analyzed. Patients with FCs from L4 to S1 > 10° and radiculopathy ipsilateral to the concavity of the FC were eligible for study inclusion and had undergone three categories of surgery: 1) FC only (FC group), 2) lower thoracic to sacrum (LT group), or 3) upper thoracic to sacrum (UT group). Primary outcomes were the rates of revision surgery and complications. Secondary outcomes were estimated blood loss, length of hospital stay, and discharge destination. Spinopelvic parameters were measured, and patients were stratified accordingly.RESULTSOf the 99 patients eligible for inclusion in the study, 27 were in the FC group, 46 in the LT group, and 26 in the UT group. There were no significant preoperative differences in age, sex, smoking status, prior operation, FC magnitude, pelvic tilt (PT), sagittal vertical axis (SVA), coronal balance, pelvic incidence–lumbar lordosis (PI-LL) mismatch, or proportion of well-aligned spines (SVA < 5 cm, PI-LL mismatch < 10°, and PT < 20°) among the three treatment groups. Mean follow-up was 30 (range 12–112) months, with a minimum 1-year follow-up. The FC group had a lower medical complication rate (22% [FC] vs 57% [LT] vs 58% [UT], p = 0.009) but a higher rate of extension surgery (26% [FC] vs 13% [LT] vs 4% [UT], p = 0.068). The respective average estimated blood loss (592 vs 1950 vs 2634 ml, p < 0.001), length of hospital stay (5.5 vs 8.3 vs 8.3 days, p < 0.001), and rate of discharge to acute rehabilitation (30% vs 46% vs 85%, p < 0.001) were all lower for FC and highest for UT.CONCLUSIONSTreatment of the FC only is associated with a lower complication rate, shorter hospital stay, and less blood loss than complete scoliosis treatment. However, there is a higher associated rate of extension of the construct to the lower or upper thoracic levels, and patients should be counseled when considering their options.

Background: Mini-open thoracoscopic-assisted thoracotomy (MOTA) has been introduced to mitigate disadvantages of conventional open anterior or conventional posterior only thoracoscopic procedures. Here, we evaluated the results of utilizing the MOTA technique to perform anterior decompression/fusion for 22 traumatic thoracic fractures. Methods: There were 22 patients with unstable thoracic burst fractures (TBF) who underwent surgery utilizing the MOTA thoracotomy technique. Multiple variables were studied including; the neurological status of the patient preoperatively/postoperatively, the level and type of fracture, associated injuries, operative time, estimated blood loss, chest tube drainage (intercostal drainage), length of hospital stay (LOS), and complication rate. Results: In 22 patients (averaging 35.5 years of age), T9 and T12 vertebral fractures were most frequently encountered. There were 20 patients who had single level and 2 patients who had two-level fractures warranting corpectomies. Average operating time and blood loss for single-level corpectomy were 91.5 ± 14.5 min and 311 ml and 150 ± 18.6 min and 550 ml for two levels, respectively. Mean hospital stay was 5 days. About 95.45% of cases showed fusion at latest follow-up. Average preoperative kyphotic angle corrected from 34.2 ± 3.5° to 20.5 ± 1.0° postoperatively with an average correction of 41.1% and correction loss of 2.4%. Conclusion: We concluded that utilization of the MOTA technique was safe and effective for providing decompression/fusion of traumatic TBF.

Object Outside of the patient population with achondroplasia, neurogenic claudication is rare in the pediatric age group. Neurogenic claudication associated with posterior vertebral rim fracture is even more uncommon but nonetheless causes pain and disability in affected children and adolescents. The purpose of this study was to describe the surgical results of 3 adolescents presenting with neurogenic claudication and posterior vertebral rim fracture when treated with laminectomy alone. Methods The medical and operative records of the 3 pediatric patients were retrospectively reviewed. Presenting signs and symptoms and CT findings, such as the interpedicular distances between T-12 and L-5, were obtained. Perioperative results were assessed, including operative time, blood loss, length of hospital stay, and complications. Findings at latest follow-up were also recorded, including a patient satisfaction survey. Results The 3 patients (1 girl and 2 boys) had a mean age of 14.7 years (range 14–15 years) and underwent follow-up for a mean of 11.3 months (range 5–18 months). Notable preoperative signs and symptoms included back pain (all patients), leg pain (all patients), leg numbness (1 patient), and leg weakness (1 patient). No patient presented with bowel and/or bladder dysfunction. The mean blood loss during laminectomy was 123 ml (range 20–300 ml), and the mean length of hospital stay was 4.3 days (range 3–6 days). On average, decompression was performed at 2.2 levels (range 2–2.5 levels). All 3 patients reported at most recent follow-up that they were “satisfied” with the surgery. There was 1 complication of instability from an iatrogenic pars fracture, which required reoperation and posterior instrumented fusion. Conclusions To the best of the authors' knowledge, this report represents the first surgical series of pediatric neurogenic claudication associated with posterior vertebral rim fractures. Pediatric neurosurgeons may infrequently encounter neurogenic claudication associated with a posterior vertebral rim fracture in children. To treat children with neurogenic claudication associated with posterior vertebral rim fractures, a simple laminectomy may be a safe and efficacious alternative to discectomy and removal of fracture fragments.

Objectives. The warm ischemia time (WIT) is key to successful laparoscopic partial nephrectomy (LPN). The aim of this study was to perform a meta-analysis comparing the self-retaining barbed suture (SRBS) with a non-SRBS for parenchymal repair during LPN. Methods. A systematic search of PubMed, Scopus, and the Cochrane Library was performed up to March 2018. Inclusion criteria for this study were randomized controlled trials (RCTs) and observational comparative studies assessing the SRBS and non-SRBS for parenchymal repair during LPN. Outcomes of interest included WIT, complications, overall operative time, estimated blood loss, length of hospital stay, and change of renal function. Results. One RCT and 7 retrospective studies were identified, which included a total of 461 cases. Compared with the non-SRBS, use of the SRBS for parenchymal repair during LPN was associated with shorter WIT ( P < .00001), shorter overall operative time ( P < .00001), lower estimated blood loss ( P = .02), and better renal function preservation ( P = .001). There was no significant difference between the SRBS and non-SRBS with regard to complications ( P = .08) and length of hospital stay ( P = .25). Conclusions. The SRBS for parenchymal repair during LPN can significantly shorten the WIT and overall operative time, decrease blood loss, and preserve renal function.

OBJECT The authors present a retrospective cohort study examining complications in patients undergoing surgery for craniosynostosis using both minimally invasive endoscopic and open approaches. METHODS Over the past 10 years, 295 nonsyndromic patients (140 undergoing endoscopic procedures and 155 undergoing open procedures) and 33 syndromic patients (endoscopic procedures in 10 and open procedures in 23) met the authors’ criteria. Variables analyzed included age at surgery, presence of a preexisting CSF shunt, skin incision method, estimated blood loss, transfusions of packed red blood cells, use of intravenous steroids or tranexamic acid, intraoperative durotomies, procedure length, and length of hospital stay. Complications were classified as either surgically or medically related. RESULTS In the nonsyndromic endoscopic group, the authors experienced 3 (2.1%) surgical and 5 (3.6%) medical complications. In the nonsyndromic open group, there were 2 (1.3%) surgical and 7 (4.5%) medical complications. Intraoperative durotomies occurred in 5 (3.6%) endoscopic and 12 (7.8%) open cases, were repaired primarily, and did not result in reoperations for CSF leakage. Similar complication rates were seen in syndromic cases. There was no death or permanent morbidity. Additionally, endoscopic procedures were associated with significantly decreased estimated blood loss, transfusions, procedure length, and length of hospital stay compared with open procedures. CONCLUSIONS Rates of intraoperative durotomies and surgical and medical complications were comparable between endoscopic and open techniques. This is the largest direct comparison to date between endoscopic and open interventions for synostosis, and the results are in agreement with previous series that endoscopic surgery confers distinct advantages over open surgery in appropriate patient populations.

Object The goal of this study was to assess the operative outcomes of adult patients with scoliosis who were treated surgically with minimally invasive correction and fusion. Methods This was a retrospective study of 28 consecutive patients who underwent minimally invasive correction and fusion over 3 or more levels for adult scoliosis. Hospital and office charts were reviewed for clinical data. Functional outcome data were collected at each visit and at the last follow-up through self-administered questionnaires. All radiological measurements were obtained using standardized computer measuring tools. Results The mean age of the patients in the study was 67.7 years (range 22–81 years), with a mean follow-up time of 22 months (range 13–37 months). Estimated blood loss for anterior procedures (transpsoas discectomy and interbody fusions) was 241 ml (range 20–2000 ml). Estimated blood loss for posterior procedures, including L5–S1 transsacral interbody fusion (and in some cases L4–5 and L5–S1 transsacral interbody fusion) and percutaneous screw fixation, was 231 ml (range 50–400 ml). The mean operating time, which was recorded from incision time to closure, was 232 minutes (range 104–448 minutes) for the anterior procedures, and for posterior procedures it was 248 minutes (range 141–370 minutes). The mean length of hospital stay was 10 days (range 3–20 days). The preoperative Cobb angle was 22° (range 15–62°), which corrected to 7° (range 0–22°). All patients maintained correction of their deformity and were noted to have solid arthrodesis on plain radiographs. This was further confirmed on CT scans in 21 patients. The mean preoperative visual analog scale and treatment intensity scale scores were 7.05 and 53.5; postoperatively these were 3.03 and 25.88, respectively. The mean preoperative 36-Item Short Form Health Survey and Oswestry Disability Index scores were 55.73 and 39.13; postoperatively they were 61.50 and 7, respectively. In terms of major complications, 2 patients had quadriceps palsies from which they recovered within 6 months, 1 sustained a retrocapsular renal hematoma, and 1 patient had an unrelated cerebellar hemorrhage. Conclusions Minimally invasive surgical correction of adult scoliosis results in mid- to long-term outcomes similar to traditional surgical approaches. Whereas operating times are comparable to those achieved with open approaches, blood loss and morbidity appear to be significantly lower in patients undergoing minimally invasive deformity correction. This approach may be particularly useful in the elderly.

OBJECTIVE Circumferential minimally invasive spine surgery (cMIS) for adult scoliosis has become more advanced and powerful, but direct comparison with traditional open correction using prospectively collected data is limited. The authors performed a retrospective review of prospectively collected, multicenter adult spinal deformity data. The authors directly compared cMIS for adult scoliosis with open correction in propensity-matched cohorts using health-related quality-of-life (HRQOL) measures and surgical parameters. METHODS Data from a prospective, multicenter adult spinal deformity database were retrospectively reviewed. Inclusion criteria were age > 18 years, minimum 1-year follow-up, and one of the following characteristics: pelvic tilt (PT) > 25°, pelvic incidence minus lumbar lordosis (PI-LL) > 10°, Cobb angle > 20°, or sagittal vertical axis (SVA) > 5 cm. Patients were categorized as undergoing cMIS (percutaneous screws with minimally invasive anterior interbody fusion) or open correction (traditional open deformity correction). Propensity matching was used to create two equal groups and to control for age, BMI, preoperative PI-LL, pelvic incidence (PI), T1 pelvic angle (T1PA), SVA, PT, and number of posterior levels fused. RESULTS A total of 154 patients (77 underwent open procedures and 77 underwent cMIS) were included after matching for age, BMI, PI-LL (mean 15° vs 17°, respectively), PI (54° vs 54°), T1PA (21° vs 22°), and mean number of levels fused (6.3 vs 6). Patients who underwent three-column osteotomy were excluded. Follow-up was 1 year for all patients. Postoperative Oswestry Disability Index (ODI) (p = 0.50), Scoliosis Research Society–total (p = 0.45), and EQ-5D (p = 0.33) scores were not different between cMIS and open patients. Maximum Cobb angles were similar for open and cMIS patients at baseline (25.9° vs 26.3°, p = 0.85) and at 1 year postoperation (15.0° vs 17.5°, p = 0.17). In total, 58.3% of open patients and 64.4% of cMIS patients (p = 0.31) reached the minimal clinically important difference (MCID) in ODI at 1 year. At 1 year, no differences were observed in terms of PI-LL (p = 0.71), SVA (p = 0.46), PT (p = 0.9), or Cobb angle (p = 0.20). Open patients had greater estimated blood loss compared with cMIS patients (1.36 L vs 0.524 L, p < 0.05) and fewer levels of interbody fusion (1.87 vs 3.46, p < 0.05), but shorter operative times (356 minutes vs 452 minutes, p = 0.003). Revision surgery rates between the two cohorts were similar (p = 0.97). CONCLUSIONS When cMIS was compared with open adult scoliosis correction with propensity matching, HRQOL improvement, spinopelvic parameters, revision surgery rates, and proportions of patients who reached MCID were similar between cohorts. However, well-selected cMIS patients had less blood loss, comparable results, and longer operative times in comparison with open patients.

OBJECT Cervical kyphosis can lead to spinal instability, spinal cord injury, and disability. The correction of cervical kyphosis is technically challenging, especially in severe cases. The authors describe the anterior sequential interbody dilation technique for the treatment of cervical kyphosis and evaluate perioperative outcomes, degree of correction, and long-term follow-up outcomes associated with the technique. METHODS In the period from 2006 to 2011, a consecutive cohort of adults with cervical kyphosis (Cobb angles ≥ 0°) underwent sequential interbody dilation, a technique entailing incrementally increased interbody distraction with the sequential placement of larger spacers (at least 1 mm) in the discectomy and/or corpectomy spaces. The authors retrospectively reviewed these patients, and primary outcomes of interest included kyphosis correction, blood loss, hospital stay, complications, Nurick grade, pain, reoperation, and pseudarthrosis. A subgroup analysis among patients with preoperative kyphosis of 0°–9° (mild), 10°–19° (moderate), and ≥ 20° (severe) was performed. RESULTS One hundred patients were included in the study: 74 with mild preoperative cervical kyphosis, 19 with moderate, and 7 with severe. The mean patient age was 53.1 years, and 54.0% of the patients were male. Mean estimated blood loss was 305.6 ml, and the mean length of hospital stay was 5.2 days. The overall complication rate was 9.0%, and there were no deaths. Sixteen percent of patients underwent supplemental posterior fusion. There was significant correction in cervical alignment (p < 0.001), and the mean overall kyphosis correction was 12.4°. Patients with severe preoperative kyphosis gained a correction of 24.7°, those with moderate kyphosis gained 17.8°, and those with mild kyphosis gained 10.1°. A mean correction of 32.0° was obtained if 5 levels were addressed. The mean follow-up was 26.8 months. The reoperation rate was 4.7%. At follow-up, there was significant improvement in visual analog scale neck pain (p = 0.020) and Nurick grade (p = 0.037). The pseudarthrosis rate was 6.3%. CONCLUSIONS Sequential interbody dilation is a feasible and effective method of correcting cervical kyphosis. Complications and reoperation rates are low. Similar benefits are seen among all severities of kyphosis, and greater correction can be achieved in more severe cases.

The objective of this study was to evaluate and compare operative and postoperative results and differences among laparoscopic, vaginal, and abdominal hysterectomies performed at the Department of Obstetrics and Gynecology of Kaunas University of Medicine Hospital. Methods. A retrospective review of medical histories was performed for women who had undergone three different types of hysterectomies (laparoscopic, vaginal, and abdominal) at the Department of Obstetrics and Gynecology of Kaunas University of Medicine Hospital during 2004–2005. Results. A total of 602 hysterectomies were performed: 51 (8.5%) laparoscopic, 203 (33.7%) vaginal, and 348 (57.8%) abdominal. The lowest complication rate occurred in patients who underwent laparoscopic hysterectomy (n=5, 9.8%) and the highest – abdominal hysterectomy (n=88, 25.2%) (P<0.05). More complication occurred after abdominal as compared to vaginal hysterectomy (n=88, 25.2% vs. n=20, 9.9%, respectively; P<0.05). There was no statistically significant difference in complication rate comparing laparoscopic and vaginal hysterectomies (P=0.26). The amount of blood loss depended on the type of hysterectomy – less blood was lost during laparoscopic and more during abdominal hysterectomy (123.4 vs. 308.5 mL, respectively; P<0.01). A significantly higher blood loss was observed during abdominal hysterectomy as compared to vaginal (195.3 mL) and vaginal as compared to laparoscopic hysterectomy (P<0.01). The mean length of hospital stay differed comparing all three types of hysterectomies: the shortest stay of 8.6 days was after laparoscopic, the longest of 13.7 days – after abdominal hysterectomy. The mean hospital stay was statistically significant shorter for vaginal hysterectomy compared to abdominal hysterectomy (9.1 vs. 13.7 days, P<0.01). The difference in mean length of hospital stay was insignificant comparing laparoscopic and vaginal hysterectomies (P>0.05). Conclusions. Abdominal hysterectomy was the most common procedure performed. The type of hysterectomy influenced the rate of complications – the lowest complication rate was after laparoscopic and vaginal hysterectomies. The amount of blood loss depended on the type of hysterectomy – the lowest was during laparoscopic hysterectomy. Abdominal hysterectomy required on average a longer hospital stay compared with laparoscopic and vaginal hysterectomies.

OBJECT Spinal metastases most commonly affect the vertebral bodies of the spinal column, and spinal cord compression is an indication for surgery. Commonly, an open posterior approach is employed to perform a transpedicular costotransversectomy or lateral extracavitary corpectomy. Because of the short life expectancies in patients with metastatic spinal disease, decreasing the morbidity of surgical treatment and recovery time is critical. One potential approach to decreasing morbidity is utilizing minimally invasive surgery (MIS). Although significant advances have been made in MIS of the spine, data supporting the utility of MIS are still emerging. This study compared outcomes of patients who underwent mini-open versus traditional open transpedicular corpectomy for spinal metastases in the thoracic spine. METHODS A consecutive cohort from 2006 to 2013 of 49 adult patients who underwent thoracic transpedicular corpectomies for spinal metastases was retrospectively identified. Patients were categorized into one of 2 groups: open surgery and mini-open surgery. Mini-open transpedicular corpectomy was performed with a midline facial incision over only the corpectomy level of interest and percutaneous instrumentation above and below that level. The open procedure consisted of a traditional posterior transpedicular corpectomy. Chi-square test, 2-tailed t-test, and ANOVA models were employed to compare perioperative and follow-up outcomes between the 2 groups. RESULTS In the analysis, there were 21 patients who had mini-open surgery and 28 patients who had open surgery. The mean age was 57.9 years, and 59.2% were male. The tumor types encountered were lung (18.3%), renal/bladder (16.3%), breast (14.3%), hematological (14.3%), gastrointestinal tract (10.2%), prostate (8.2%), melanoma (4.1%), and other/unknown (14.3%). There were no significant intergroup differences in demographics, comorbidities, neurological status (American Spinal Injury Association [ASIA] grade), number of corpectomies performed, and number of levels instrumented. The open group had a mean operative time of 413.6 minutes, and the mini-open group had a mean operative time of 452.4 minutes (p = 0.329). Compared with the open group, the mini-open group had significantly less blood loss (917.7 ml vs 1697.3 ml, p = 0.019) and a significantly shorter hospital stay (7.4 days vs 11.4 days, p = 0.001). There was a trend toward a lower perioperative complication rate in the mini-open group (9.5%) compared with the open group (21.4%), but this was not statistically significant (p = 0.265). At follow-up, there were no significant differences in ASIA grade (p = 0.342), complication rate after the 30-day postoperative period (p = 0.999), or need for surgical revision (p = 0.803). The open approach had a higher overall infection rate of 17.9% compared with that in the mini-open approach of 9.5%, but this was not statistically significant (p = 0.409). CONCLUSIONS The mini-open transpedicular corpectomy is associated with less blood loss and shorter hospital stay compared with open transpedicular corpectomy. The mini-open corpectomy also trended toward lower infection and complication rates, but these did not reach statistical significance.

Abstract Background The aim of this study was to analyze the feasibility and the safety of laparoscopic nephrectomy in the treatment of pathologies of the upper urinary tract through the experience of the Urology B department. Methods We have retrospectively and monocentrally selected patients who underwent laparoscopic nephrectomy from January 2017 to December 2019. The collection was carried out on archived files, based on demographic, clinical and perioperative data. The primary endpoint was the occurrence of complications and secondarily the length of the operation and the length of hospital stay. The statistical analysis was carried out using the SPSS software. Results A total of 68 patients were included in our series. The average age of our patients was 57.8 years. There was a slight female predominance: 39 female patients (57.4%) for 29 male patients (42.6%). Indications for nephrectomy were dominated by renal tumor (33.82%) followed by lithiasis (16.17%) and non-functioning kidney (16.17%) at the same rank. During the study period, 31 (45.6%) simple nephrectomy, 26 (38.2%) total nephrectomy, 1 (1.5%) partial nephrectomy and 10 (14.7%) nephroureterectomy were performed in our department. In our series, the average operating time was 180 min. Estimated blood loss averaged 321.8 ml with extremes of a few milliliter to 1100 ml. Intraoperative complications were reported in 10 (14.7%) patients; conversion was necessary in 6 cases (8.82%). The postoperative follow-up was straightforward in 53 (77.94%) patients with an average hospital stay of 3.6 days. The rate of postoperative complications according to Clavien–Dindo was 22.1%. Histological examination of the nephrectomies carried out in our department revealed mainly chronic non-specific pyelonephritis in 24 (35.3%) patients, followed by renal cell carcinoma in 23 (33.82%) patients and urothelial carcinoma in 9 (13.2%) patients. Conclusion Laparoscopic nephrectomy appears to be an efficient and reliable technique. This technique has led to a significant improvement in operative morbidity, mainly represented by the length of hospital stay, operating time and blood loss.
