Treatment of Holocord Syringomyelia-Chiari Complex by Posterior Fossa Decompression and a Syringosubarachnoid Shunt in a Single-Stage Single Approach.

BACKGROUND: Posterior fossa decompression with expansive duraplasty is the first-line surgical approach for the treatment of symptomatic syringomyelia associated with Chiari malformation. Despite good decompression, the clinical failure rate is reported to be up to 26%. A syringosubarachnoid (S-S) shunt may be used as a secondary option. METHODS: In this paper we describe a single-institution experience of three cases of holocord syringomyelia-Chiari complex treated with foramen magnum decompression, expansive duraplasty and an S-S shunt carried out in a single-stage single approach. Following a standard suboccipital craniectomy, patients were submitted to syrinx fenestration and simultaneous insertion of an S-S shunt through a 1-mm posterior midline myelotomy at the C2 level prior to expansive dural reconstruction. RESULTS: Postoperative imaging showed immediate reduction of the holocord cavities. Preoperative neurological deficits rapidly improved significantly and were stabilized at follow-up. CONCLUSION: In our experience the positioning of the shunt catheter at a high level of the spinal cord (C2) did not add a significant risk of morbidity and obviated the need for a second operation and/or a separate incision in cases of clinical failure. This technique avoided the risk associated with a second surgery and its morbidity, and allowed prompt clinical recovery.

Laparo-endoscopic management of chole-choledocholithiasis: Rendezvous or intraoperative ERCP? A single tertiary care center experience.

Introduction: The management of chole-choledocholithiasis remains a matter of debate to preserve minimal invasive management and different options have been proposed, with single- or two-stage approaches. Two techniques of single-stage approach are intraoperative ERCP and laparoscopic rendezvous, which have the great advantage of reducing the length of hospital stay with increased patient compliance. This retrospective study aims to evaluate and compare the efficacy and safety of intraoperative ERCP and rendezvous technique for more than 15 years. Materials and methods: Clinical records of 113 patients who underwent single-stage management for chole-choledocholithiasis between January 2003 and December 2020 were retrospectively reviewed using a prospectively maintained database. Patients were separated into two groups: those managed with intraoperative ERCP and those with rendezvous, and their intraoperative and postoperative parameters were compared. All patients were followed up for 6 months in an outpatient setting. Results: A total of 68 (60%) patients were treated with intraoperative ERCP, while the remaining 45 (40%) were treated with rendezvous. There were no significant differences in terms of comorbidities. ERCP was performed with a median operative time of 145 min (104-168) and an endoscopic time of 27 min (15-36). Meanwhile, rendezvous was performed with a significantly lower operative [120 min (94-147)] and endoscopic time [15 min (12-22)]. No intraoperative complications were recorded. Patients treated with rendezvous had a significantly shorter median hospitality stay [4 (3-5) vs. 3 (2-4) days, p < 0.05]. No hospital readmissions or mortalities were observed in either group after 30 days. Ten mild pancreatitis cases were observed, mainly in the intraoperative ERCP group (9 vs. 1, p < 0.05), and all were treated conservatively. Only two patients treated with intraoperative ERCP developed biliary complications later on. Conclusion: Laparoscopic rendezvous should be considered a preferable alternative to intraoperative ERCP for the treatment of patients with concomitant CBD stones and gallstones.

Revisiting the surgical corridors for cervical Type IIb-c dumbbell neurofibroma: A series of two unconventional approaches and review of literature.

BACKGROUND: Cervical sub-axial dumbbell neurofibromas (NFs) account for nearly 20% of all NFs, with prognosis depending on the extent of excision. When majority of tumor is extra-foraminal (Tomaya's Type IIb and c), certain unconventional anterolateral or posterolateral neck approaches are used for maximum safe excision. In our article, we provide a brief review of the literature regarding various surgical approaches, emphasizing the utility of posterolateral or combined anterior and posterior neck approaches for such giant NF. METHODS: We performed a retrospective analysis of prospectively maintained surgical databases, from our hospital discharge codes, for all cervical Type IIb-c dumbbell NF patients, who underwent surgery at our institution between 2015 and 2019. Clinical variables included age at admission, clinical presentation, and surgical difficulties, and the outcome was analyzed. RESULTS: Four patients of age ranging from 22 to 45 years (M:F 3:1) were operated by posterolateral (n = 3) and combined anteroposterior (n = 1) approach. Three patients underwent near-total excision and one patient had total excision. One patient with tumor capsule attached to roots of upper brachial plexus had motor deficit, who was re-admitted for neurotization. There was no intraoperative complication. CONCLUSION: Posterolateral approach for cervical dumbbell giant NFs is safe, effective, and promises maximum safe excision. The major blood vessels including carotid artery or jugular veins in neck and vertebral artery at foraminal portion are directly under vision and control of surgeon. Despite near-total excision, wherein small part of adhered capsule is left, recurrence rate is low.

Treatment Strategies and Outcome of the Exstrophy-Epispadias Complex in Germany: Data From the German CURE-Net.

Introduction: To evaluate the impact of reconstructive strategies and post-operative management on short- and long-term surgical outcome and complications of classical bladder exstrophy (CBE) patients' comprehensive data of the multicenter German-wide Network for Congenital Uro-Rectal malformations (CURE-Net) were analyzed. Methods: Descriptive analyses were performed between 34 prospectively collected CBE patients born since 2009, median 3 months old [interquartile range (IQR), 2-4 months], and 113 cross-sectional patients, median 12 years old (IQR, 6-21 years). Results: The majority of included individuals were males (67%). Sixty-eight percent of the prospectively observed and 53% of the cross-sectional patients were reconstructed using a staged approach (p = 0.17). Although prospectively observed patients were operated on at a younger age, the post-operative management did not significantly change in the years before and after 2009. Solely, in prospectively observed patients, peridural catheters were used significantly more often (p = 0.017). Blood transfusions were significantly more frequent in males (p = 0.002). Only half of all CBE individuals underwent inguinal hernia repair. Cross-sectional patients after single-stage reconstructions showed more direct post-operative complications such as upper urinary tract dilatations (p = 0.0021) or urinary tract infections (p = 0.023), but not more frequent renal function impairment compared to patients after the staged approach (p = 0.42). Continence outcomes were not significantly different between the concepts (p = 0.51). Self-reported continence data showed that the majority of the included CBE patients was intermittent or continuous incontinent. Furthermore, subsequent consecutive augmentations and catheterizable stomata did not significantly differ between the two operative approaches. Urinary diversions were only reported after the staged concept. Conclusions: In this German multicenter study, a trend toward the staged concept was observed. While single-stage approaches tended to have initially more complications such as renal dilatation or urinary tract infections, additional surgery such as augmentations and stomata appeared to be similar after staged and single-stage reconstructions in the long term.

Minimally Invasive Single-Stage Removal of a Thoracic Dumbbell Tumor from a Posterior Approach: 2-Dimensional Operative Video.

Dumbbell-shaped thoracic tumors usually involve the spinal canal and the posterior thoracic cavity. Gross total resection is the treatment of choice, but techniques for surgical excision remain controversial. An anterolateral transthoracic approach may remove the paravertebral component of the tumor, but has limited or no control of the intracanal lesion. A combined posteroanterior approach requires a 2-stage surgery with significant morbidity. The preferred approach depends mainly on the tumor location, size, shape, and its specific anatomical relationship with the surrounding vital structures. We present a surgical video of a single-stage posterior minimally invasive approach for the management of a thoracic dumbbell tumor.

Single-staged resections and 3D reconstructions of the nasion, glabella, medial orbital wall, and frontal sinus and bone: Long-term outcome and review of the literature.

BACKGROUND: Aesthetic facial appearance following neurosurgical ablation of frontal fossa tumors is a primary concern for patients and neurosurgeons alike. Craniofacial reconstruction procedures have drastically evolved since the development of three-dimensional computed tomography imaging and computer-assisted programming. Traditionally, two-stage approaches for resection and reconstruction were used; however, these two-stage approaches have many complications including cerebrospinal fluid leaks, necrosis, and pneumocephalus. CASE DESCRIPTION: We present two successful cases of single-stage osteoma resection and craniofacial reconstruction in a 26-year-old female and 65-year-old male. The biopolymer implants were preselected and contoured based on imaging prior to surgery. The ideal selection of appropriate flaps for reconstruction was imperative. The flaps were well vascularized and included a pedicle for easy translocation. Using a titanium mesh biopolymer implant for reconstruction in conjunction with a forehead flap proved advantageous, and the benefits of single-stage approaches were apparent. The patients recovered quickly after the surgery with complete resection of the osteoma and good aesthetic appearance. The flap adhered to the biopolymer implant, and the cosmetic appearance years after surgery remained decent. The gap between the bone and implant was less than 2 mm. The patients are highly satisfied with the symmetrical appearance of the reconstruction. CONCLUSIONS: Advances in technology are allowing neurosurgeons unprecedented opportunities to design complex yet feasible single-stage craniofacial reconstructions that improve a patient's quality of life by enhancing facial contours, aesthetics, and symmetry.

The PAVE (peeling-assisted volume-enhancing) lift: A retrospective 6-year clinical analysis of a combined approach for facial rejuvenation.

The peeling-assisted volume-enhancing (PAVE) lift is a single-stage approach that combines superficial musculoaponeurotic system (SMAS) plication techniques with fat grafting and different peeling agents. To evaluate the safety of this approach, we analyzed the records of 159 patients who underwent surgery between 2008 and 2014. The percentage of complications observed was not higher than values reported in the literature for each treatment entity: surgical facelift: n=3 haematomas (1.89 %), n=2; temporary apraxia of the mandibular branch (1.26%); fat transfer: minor asymmetry in n = 5 cases (3.14%); peeling: temporary hyperpigmentation in trichloroacetic acid (n = 5; 3.8%) and phenol peels (n = 4; 3.1%), permanent hypopigmentation (n = 6; 5.6%), formation of skin miliae persisting longer than 2 to 3 months (n = 5; 4.6%) and prolonged erythema (n = 3; 0.28%) in phenol peels. The single-stage use of chemical peels, autologous fat transfer, and surgical rhytidectomy was safe.
