Intradermal Scalp Closure Using Barbed Suture in Cranial Tumor Surgeries: A Technical Note

Barbed versus conventional suture in elective posterior spine surgery

PURPOSE

Barbed sutures are tissue control devices that can reduce operating room time and costs. We analyzed the utility of barbed sutures in posterior spinal surgery in order to prove non-inferiority to conventional methods for wound closure.

METHODS

A cohort of patients undergoing elective posterior spinal surgery in which barbed (prospective) versus conventional sutures (retrospective) were used was analyzed. The primary endpoint was the occurrence of wound healing complications or the need for surgical revision. Secondary endpoints included postoperative stay, readmission rate, and duration and cost of wound closure.

RESULT

A total of 483 patients participated in the study, 183 in the Barbed group and 300 in the Conventional group. Wound dehiscence or seroma occurred in 3.8% and 2.7% of the Barbed and Conventional groups, respectively (p = 0.6588). Both superficial (1.6% versus 4.0%, P = 0.2378) and deep infections (2.7% versus 4.7%, p = 0.4124) occurred similarly in both groups. Overall, the rate of re-intervention due to wound healing problems was also similar (4.9% versus 5.3%, p = 0.9906), as well as, total median hospital stay, postoperative stay and 30-day re-admission rates. The average duration of wound closure (1.66 versus 4.16 min per level operated, p < 0.0001) strongly favored the Barbed group. The mean cost of wound closure per patient was higher in the Barbed group (43.23 € versus 22.67 €, p < 0.0001).

CONCLUSIONS

In elective posterior spinal procedures, the use of barbed sutures significantly reduced the duration of wound closure. The wound healing process was not hindered and the added cost related to the suture material was small.

Additional Relaxing Suturing Using Absorbable Symmetric Barbed Sutures to Help Close Scalp Defects

Closing a scalp wound with skin defects is challenging because the scalp skin lacks extensibility and closing it tends to result in a remarkable, widespread, hairless scar. Absorbable symmetric barbed suture device (Stratafix Symmetric; Ethicon, USA) allows wound closure using a pulling motion alone and provides a strong and secure closure for the high-tension area. We used this device to close wide scalp defects easily without tension and with minimized sequential scalp alopecia. The aim of this study was to show our experiences with using this technique. From January 2017 to March 2019, our relaxing suture technique was performed in 7 pediatric patients with scalp alopecia due to various lesions that ranged 23.0 ± 6.5 mm. After resecting the lesions, the galea was sutured using the 3-0 absorbable symmetric barbed suture via a running subcutaneous suture technique. The widespread wound edges were approximated by pulling the suture device. Wound closure was completed with galeal suturing and a superficial suture. We evaluated the width of the postoperative hairless scar at the final follow-up. In all 7 patients, we could approximate the widespread wound edges by pulling alone. Subsequently, the wounds could be closed without tension or difficulty. The mean width of the postoperative hairless scar was 3.3 ± 0.8 mm (range: 1.9–4.3 mm), and no complication was detected during the follow-up period. Our new relaxing suture technique using an absorbable barbed suture with symmetric anchors is a supportive and additional way to help close scalp defects.

Hair-sparing technique using absorbable intradermal barbed suture versus traditional closure methods in supratentorial craniotomies for tumor

BACKGROUND

Hair-sparing techniques in cranial neurosurgery have gained traction in recent years and previous studies have shown no difference in infection rates, yet limited data exists evaluating the specific closure techniques utilized during hair-sparing craniotomies. Therefore, it was the intention of this study to evaluate the rate of surgical site infections (SSIs) and perioperative complications associated with using an absorbable intradermal barbed suture for skin closure in hair-sparing supratentorial craniotomies for tumor in order to prove non-inferiority to traditional methods.

METHODS

A retrospective review of supratentorial craniotomies for tumor by a single surgeon from 2011 to 2017 was performed. All perioperative adverse events and wound complications, defined as a postoperative infection, wound dehiscence, or CSF leak, were compared between three different groups: (1) hair shaving craniotomies + transdermal polypropylene suture/staples for scalp closure, (2) hair-sparing craniotomies + transdermal polypropylene suture/staples for scalp closure, and (3) hair-sparing craniotomies + absorbable intradermal barbed suture for scalp closure.

RESULTS

Two hundred sixty-three patients underwent hair shaving + transdermal polypropylene suture/staples, 83 underwent hair sparing + transdermal polypropylene suture/staples, and 100 underwent hair sparing + absorbable intradermal barbed suture. Overall, 2.9% of patients experienced a perioperative complication and 4.3% developed a wound complication. In multivariable analysis, the use of a barbed suture for scalp closure and hair-sparing techniques was not predictive of any complication or 30-day readmission. Furthermore, the absorbable intradermal barbed suture cohort had the lowest overall rate of wound complications (4%).

CONCLUSIONS

Hair-sparing techniques using absorbable intradermal barbed suture for scalp closure are safe and do not result in higher rates of infection, readmission, or reoperation when compared with traditional methods.

Minimally invasive keyhole temporal lobectomy approach for supramaximal glioma resection: A safety and feasibility study

With a recent trend towards supra-maximal resection for gliomas and minimally invasive techniques, keyhole temporal lobectomies may serve an important role in neurosurgical oncology. Due to their location and proximity to eloquent brain, temporal lobe gliomas offer unique challenges that may limit the extent of resection. Here we describe a modified technique using mini-craniotomies through a keyhole approach for temporal lobectomies in glioma patients. We retrospectively reviewed data from consecutive patients who underwent temporal lobectomies for resection of gliomas from 2012 to 2018. Demographic data, extent of tumor resection, pre and post-op KPS, short term and long term complications, as well as other relevant data were collected. We identified 57 patients who underwent keyhole-mini craniotomy for temporal lobectomies for glioma. Surgical procedures were performed in 12 patients for low-grade glioma (LGG) and 45 patients for high-grade glioma (HGG). Awake craniotomies were performed in 15 of the cases, and 13 cases were for tumor recurrence. Supra-maximal resection (SMR) was achieved in 15 patients, while gross total resection (GTR) and near total resection (NTR) achieved in 32 patients and 10 patients, respectively. Average pre- and post-op KPS were equivalent, and post-operative complications requiring surgical intervention were experienced in 4 patients. Here we show that our modified keyhole craniotomy is both safe and effective in achieving SMR or GTR in glioma patients, with minimal morbidity. This minimally-invasive temporal lobectomy may be an instrumental tool for neurosurgical oncologists transitioning to less invasive techniques.
