Endoscope-assisted management of sagittal synostosis: wide vertex suturectomy and barrel stave osteotomies versus narrow vertex suturectomy

OBJECTIVE Endoscope-assisted methods for treatment of craniosynostosis have reported benefits over open calvarial vault reconstruction. In this paper, the authors evaluated 2 methods for endoscope-assisted correction of sagittal synostosis: wide vertex suturectomy and barrel stave osteotomies (WVS+BSO) and narrow vertex suturectomy (NVS). METHODS The authors evaluated patients with nonsyndromic sagittal synostosis treated with either wide vertex suturectomy (4–6 cm) and barrel stave osteotomies (WVS+BSO) or narrow vertex suturectomy (NVS) (approximately 2 cm) between October 2006 and July 2013. Prospectively collected data included patient age, sex, operative time, estimated blood loss (EBL), postoperative hemoglobin level, number of transfusions, complications, and cephalic index. Fourteen patients in the NVS group were age matched to 14 patients in the WVS+BSO group. Descriptive statistics were calculated, and Student t-tests were used to compare prospectively obtained data from the WVS+BSO group with the NVS group in a series of univariate analyses. RESULTS The mean age at surgery was 3.9 months for WVS+BSO and 3.8 months for NVS. The mean operative time for patients undergoing NVS was 59.0 minutes, significantly less than the 83.4-minute operative time for patients undergoing WVS+BSO (p < 0.05). The differences in mean EBL (NVS: 25.4 ml; WVS+BSO: 27.5 ml), mean postoperative hemoglobin level (NVS: 8.6 g/dl; WVS+BSO: 8.0 g/dl), mean preoperative cephalic index (NVS: 69.9; WVS+BSO: 68.2), and mean cephalic index at 1 year of age (NVS: 78.1; WVS+BSO: 77.2) were not statistically significant. CONCLUSIONS The NVS and WVS+BSO produced nearly identical clinical results, as cephalic index at 1 year of age was similar between the 2 approaches. However, the NVS required fewer procedural steps and significantly less operative time than the WVS+BSO. The NVS group obtained the final cephalic index in a similar amount of time postoperatively as the WVS+BSO group. Complications, transfusion rates, and EBL were not different between the 2 techniques.

Abstract Background The incidence of prostate cancer in renal transplant recipients (RTR) is similar to the general population. Radical prostatectomy (RP) is the standard of care in the management of clinically localized cancer, but is considered complicated due to the presence of adhesions, and the location of transplanted ureter/kidney. To date, a few case series or studies on RP in RTR have been published, especially in Asian patients. This study aimed to evaluate the efficacy and safety and report the experience with RP on RTR. Methods We retrospectively reviewed data of 1270 patients who underwent RP from January 2008 to March 2020, of which 5 patients were RTR. All available baseline characteristics, perioperative and postoperative data (operative time, estimated blood loss (EBL), complications, length of hospital stay, complication), pathological stage, Gleason score, surgical margin status, and pre/postoperative creatinine were reviewed. Results Of the 5 RTR who underwent RPs (1 open radical prostatectomy (ORP), 1 laparoscopic radical prostatectomy (LRP), 2 robotic-assisted laparoscopic radical prostatectomies (RALRP), and 1 Retzius-sparing RALRP (RS-RALRP)) prostatectomy, the mean age (± SD) was 70 (± 5.62) years. In LRP and RALRP cases, the standard ports were moved slightly medially to prevent graft injury. The mean operative time ranged from 190 to 365 min. The longest operative time and highest EBL (630 ml) was the ORP case due to severe adhesion in Retzius space. For LRP and RALRP cases, the operative times seemed comparable and had EBL of ≤ 300 ml. All RPs were successful without any major intra-operative complication. There was no significant change in graft function. The restorations of urinary continence were within 1 month in RS-RALRP, approximately 6 months in RALRP, and about 1 year in ORP and LRP. Three patients with positive surgical margins had prostate-specific antigen (PSA) persistence at the first follow-up and 1 had later PSA recurrence. Two patients with negative margins were free from biochemical recurrence at 47 and 3 months after their RP. Conclusions Our series suggested that all RP techniques are safe and feasible mode of treatment for localized prostate cancer in RTR.

Cranial Vault Remodeling

OBJECTIVE Isolated nonsyndromic sagittal synostosis (SS) is the most common form of craniosynostosis in children, accounting for approximately 60% of all craniosynostoses. The typical cranial measurement used to define and follow SS is the cephalic index (CI). Several surgical techniques have been suggested, but agreement on type and timing of surgery is lacking. This study aimed to evaluate the authors’ institutional experience of surgically treating SS using a modified subtotal cranial vault remodeling technique in a population-based cohort. Special attention was directed toward the effect of patient age at time of surgery on long-term CI outcome. METHODS A retrospective analysis was conducted on all patients with isolated nonsyndromic SS who were surgically treated from 2003 to 2011. Data from electronic medical records were gathered. Eighty-two patients with SS were identified, 77 fulfilled inclusion criteria, and 72 had sufficient follow-up data and were included. CI during follow-up after surgery was investigated with ANOVA and a linear mixed model. RESULTS In total, 72 patients were analyzed, consisting of 16 females (22%) and 56 males (78%). The mean ± SD age at surgery was 4.1 ± 3.1 months. Blood transfusions were received by 81% of patients (26% intraoperatively, 64% postoperatively, 9% both). The mean ± SD time in the pediatric ICU was 1.1 ± 0.25 days, and the mean ± SD total hospital length of stay was 4.6 ± 2.0 days. No patient required reoperation. The mean ± SD CI increased from 69 ± 3 to 87 ± 5 for patients who underwent surgery before 45 days of age. Surgery resulted in a larger increase in CI for patients who underwent surgery at a younger age compared with older patients (p < 0.05, Tukey’s HSD test). In the comparison of patients who underwent surgery before 45 days of age with patients who underwent surgery at 45–90, 90–180, and more than 180 days of age, the linear mixed model estimated a long-term loss of CI of 3.0, 5.5, and 7.4 points, respectively. CONCLUSIONS The modified subtotal cranial vault remodeling technique used in this study significantly improved CI in patients with SS. The best results were achieved when surgery was performed early in life.

Abstract OBJECTIVE Neurogenic paravertebral tumors are uncommon neoplasms arising from neurogenic elements within the thorax. These tumors may be dumbbell shaped, extending into the spinal canal or exclusively paraspinal. Generally encapsulated, they are located in the posterior mediastinum. In this report, we present our experience in the thoracoscopic resection of these tumors, including surgical technique and potential pitfalls. METHODS A retrospective review of patients undergoing endoscopic surgery for paravertebral tumors was undertaken. Patient demographics, charts, operative reports, and pre- and postoperative images were reviewed. RESULTS Between 1997 and 2004, 13 patients were treated thoracoscopically for paravertebral tumors in our departments. Our population consisted of four men and nine women. The median age was 44.9 years (range, 29–66 yr). Eight patients presented with pain, dyspnea, cough, and weakness. Five patients had tumors found incidentally. Sizes of the tumors varied from 3 to 9 cm. Final pathology included four neurofibromas, eight schwannomas, and one unclassified granular cell tumor. Gross total resection was achieved endoscopically in all cases. Three patients required a hemilaminectomy for resection of the intraspinal dumbbell component of the tumor during the same operation. The mean operative time was 229.5 minutes. The mean estimated blood loss was 371.1 ml. Postoperative morbidities included one each of tongue swelling, ulnar neuropathy, and intercostal hyperesthesia. The mean hospital stay was 2.8 days. CONCLUSION Paravertebral tumors in the posterior mediastinum are amenable to endoscopic removal, even in hard to reach locations. Tumors with intraspinal extension can be removed concurrently by performing a hemilaminectomy, followed by thoracoscopy, without the need for a thoracotomy.

Object Multiple surgical procedures have been described for the management of isolated nonsyndromic sagittal synostosis. Minimally invasive techniques have been recently emphasized, but these techniques necessitate the use of an endoscope and postoperative helmeting. The authors assert that a safe and effective, more “minimalistic” approach is possible, avoiding the use of endoscopic visualization and routine postoperative application of a cranial orthosis. Methods A single-institution cohort analysis was performed on 18 cases involving infants treated for isolated nonsyndromic sagittal synostosis between 2008 and 2010 using a nonendoscopic, minimally invasive calvarial vault remodeling (CVR) procedure without postoperative helmeting. The surgical technique is described. Variables analyzed were: age at time of surgery, sex, estimated blood loss (EBL), operative time, intraoperative complications, postoperative complications, length of stay, pre- and postoperative cephalic index (CI), clinical impressions, and results of a 5-question nonstandardized questionnaire administered to patient caregivers regarding outcome. Results Eleven male and 7 female infants (mean age 2.3 months) were included in the study. The mean duration of follow-up was 16.4 months (range 6–38 months). The mean procedural time was 111 minutes (range 44–161 minutes). The mean length of stay was 2.3 days (range 2–3 days). The mean EBL in all 18 patients was 101.4 ml (range 30–475 ml). One patient had significant bone bleeding resulting in an EBL of 475 ml. Excluding this patient, the mean EBL was 79.4 ml (range 30–150 ml). There were no deaths or intraoperative complications; one patient had a superficial wound infection. The mean CI was 69 preoperatively versus 79 postoperatively, a statistically significant difference (p < 0.0001). Two patients were offered helmeting for suboptimal surgical outcome; one family declined and the single helmeted patient showed improvement at 2 months. No patient has undergone further surgery for correction of primary deformity, secondary deformities, or bony irregularities. Complete questionnaire data were available for 14 (78%) of the 18 patients; 86% of the respondents were pleased with the cosmetic outcome, 92% were happy to have avoided helmeting, 72% were doubtful that helmeting would have provided more significant correction, and 86% were doubtful that further surgery would be necessary. Small, palpable, aesthetically insignificant skull irregularities were reported by family members in 6 cases (43%). Conclusions The authors present a nonendoscopic, minimally invasive CVR procedure without postoperative helmeting. Their small series demonstrates this to be a safe and efficacious procedure for isolated nonsyndromic sagittal synostosis, with improvements in CI at a mean follow-up of 16.1 months, commensurate with other techniques, and with overall high family satisfaction. Use of a CVR cranial orthosis in a delayed fashion can be effective for the infrequent patient in whom this approach results in suboptimal correction.

Background Clinical results and recurrence rate after microendoscopic diskectomy (MED) with long-term follow-up is still unclear, in spite of its relatively long history. Materials and Methods A total of 112 who underwent MED participated in this study. Operative time, blood loss, serum C-reactive protein (CRP), creatine kinase (CK), and visual analog scale (VAS) were evaluated as indexes of surgical invasiveness. The 36-Item Short Form Survey Instrument (SF-36), Japanese Orthopaedic Association (JOA) score, patient satisfaction, and recurrence were also evaluated with a follow-up of at least 5 years. Results The mean operative time was 86.7 minutes, and the mean blood loss was 35.7 mL. The mean CRP on postoperative day 3 and CK on the first postoperative day was 0.72 mg/dL and 224.6 IU/L, respectively, and VAS to assess surgical site pain on the first postoperative day was 24.9 mm on average. The improvement rate in the JOA score was 68.7%. The physical component summary of SF-36 in norm-based scoring was improved from 23.4 to 48.6. Overall, 90.8% of patients evaluated their response to the surgery as extremely satisfied or satisfied. The recurrence rate was 10.5%, and reoperation was performed in 7.9% of patients. Conclusions MED is a technique that offers both reduced invasiveness and good long-term clinical results.

OBJECTIVEThe aims of enhanced recovery after surgery (ERAS) are to improve surgical outcomes, shorten hospital stays, and reduce complications. The objective of this study was to introduce ERAS with biportal endoscopic transforaminal lumbar interbody fusion (TLIF) and to investigate the clinical results.METHODSPatients were divided into two groups based on the fusion procedures. Patients who received microscopic TLIF without ERAS were classified as the non-ERAS group, whereas those who received percutaneous biportal endoscopic TLIF with ERAS were classified as the ERAS group. The mean Oswestry Disability Index (ODI) and visual analog scale (VAS) scores were compared between the two groups. In addition, demographic characteristics, diagnosis, mean operative time, estimated blood loss (EBL), fusion rate, readmissions, and complications were investigated and compared.RESULTSForty-six patients were grouped into the non-ERAS group (microscopic TLIF without ERAS) and 23 patients into the ERAS group (biportal endoscopic TLIF with ERAS). The VAS score for preoperative back pain on days 1 and 2 was significantly higher in the non-ERAS group than in the ERAS group (p < 0.05). The mean operative duration was significantly higher in the ERAS group than in the non-ERAS group, while the mean EBL was significantly lower in the ERAS group than in the non-ERAS group (p < 0.05). There was no significant difference in fusion rate between the two groups (p > 0.05). Readmission was required in 2 patients who were from the non-ERAS group. Postoperative complications occurred in 6 cases in the non-ERAS group and in 2 cases in the ERAS group.CONCLUSIONSPercutaneous biportal endoscopic TLIF with an ERAS pathway may have good aspects in reducing bleeding and postoperative pain. Endoscopic fusion surgery along with the ERAS concept may help to accelerate recovery after surgery.

Introduction: Irreducible atlantoaxial dislocation (IAAD) has been challenging for spine surgeons. Various methods have been used to treat IAAD, but no consensus has been reached. This study aimed to retrospectively analyze the efficacy of anterior submandibular retropharyngeal release and posterior reduction and fixation for IAAD. Methods: From March 2007 to May 2015, 13 patients diagnosed with IAAD underwent anterior submandibular retropharyngeal release and sequential posterior reduction and fixation. The operation time, blood loss, postoperative complications, and Japanese Orthopaedic Association (JOA) scores were retrospectively recorded. Results: The surgeries were accomplished successfully. The mean operative time was about 3.8 h. The mean estimated blood loss was about 130 mL. The patients experienced postoperative pharyngeal pain. Only one patient had a vague voice and increased oral discharge postoperatively. At the final follow-up, JOA scores had significantly increased ( p < 0.05), and all the patients had solid bony fusion. Conclusion: The present study reinforces the efficacy and safety of anterior submandibular retropharyngeal release and posterior reduction and fixation for IAAD. It can achieve satisfactory clinical outcomes and is safe for experienced spine surgeons.

Abstract Background To compare the efficacy of the operative techniques, complications, reduction quality and hip functional recovery by using the supra-ilioinguinal approach and the modified Stoppa approach for the management of acetabular fractures. Methods A consecutive cohort of 60 patients from September 2014 to October 2017 with displaced acetabular fractures involving the quadrilateral plate were treated operatively with supra-ilioinguinal approach (group A) and modified Stoppa approach (group B), respectively. There were 36 patients in group A and 24 patients in group B. The surgical details, complications, radiographic and clinical results were recorded. The quality of reduction was assessed by measuring the residual step and gap displacement of postoperative CT with a standardized digital method. Results The complications, reduction quality (gaps and steps) and hip function recovery had no significant statistical difference in approaches. The mean operative time was shorter and the mean intraoperative haemorrhage was less in group A. There were statistical differences in the operative time (P = 0.025) and intraoperative haemorrhage (P = 0.003) between the supra-ilioinguinal approach and the modified Stoppa approach. Conclusion Compared to the modified Stoppa approach, the supra-ilioinguinal approach provides a closer visualization to the quadrilateral plate, the operative time was shorter and the intraoperative haemorrhage was clearly less. It is at least equal to or could be a better choice to deal with complicated acetabular fractures especially involving the quadrilateral plate and the anterior one third of the iliac bone.

Object. The authors sought to minimize scalp incisions, blood loss, and operative time by using endoscopically assisted strip craniectomies and barrel-stave osteotomies to treat infants with sagittal suture synostosis. Methods. Four patients, aged 2, 4, 9, and 12 weeks, who presented with scaphocephaly underwent endoscopic midline craniectomies through small midline scalp incisions. The mean operative time for the procedure was 1.68 hours (range 1.15–2.8 hours); the mean blood loss was 54.2 ml (range 12–150 ml). Three patients did not require blood transfusions and were discharged within 24 hours. Postoperatively, all patients were fitted with custom cranial molding helmets. Follow-up evaluation ranged between 8 and 15 months. All patients had successful correction of their scaphocephaly with no mortalities, morbidities, or complications. Conclusions. The use of endoscopic techniques for early correction of sagittal synostosis is safe; decreases blood loss, operative time, and hospitalization costs; and provides excellent early surgical results.

Objectives: To analyze the feasibility, safety and advantages of Laparo-Endoscopic Single-site Surgery radical prostatectomy (LESS-RP) based on our personal experience. Patients and methods: Details of 520 patients were retrospectively analyzed, from 2009 to 2019. Extraperitoneal approach, with only two accesses (2.5 cm and 5 mm respectively) was used to perform radical prostatectomy. Perioperative characteristics and postoperative oncologic and functional outcomes are reported. Results: The mean age was 66.6 ± 5.6 years. Mean PSA level was 9 ± 3.5 ng/ml. According to D’Amico classification, the percentage of patients with low-, intermediate-, and high-risk disease cases were 116 (22.4%), 275 (52.8%), and 129 (24.8%) respectively. Mean operative time was 156 ± 43 min. Mean estimated blood loss was 214 ± 93 ml. Positive surgical margins (PSMs) were detected in 110 (21.2%) patients. PSM rates in pT2 and pT3 stages were 20.1% and 22.9%, respectively. The overall complication rate was 9.2%, based on the modified Clavien classification. The 12 months continence and potency rates were 90.9% and 49.1%, respectively. The biochemical recurrence rate was 6.8%, at the median follow-up time of 26.7 months (IQR 12–32). Conclusions: Our analyses show that LESS-RP is a safe procedure, if performed by surgeons with adequate experience and skills. Unlike the classic laparoscopic prostatectomy, this technique allows better aesthetic and psychological results, reduced postoperative pain, and a faster return to normal daily activity with the same functional and oncological results.
