Successful Application of Buccal Mucosal Graft Transplant in Resistant Suture Exposure of Transscleral-Sutured Posterior Chamber Intraocular Lens.

We report the successful reconstruction of suture exposure with the oral mucosal graft in a patient with suture exposure after transscleral-sutured posterior chamber intraocular lens implantation. The 70-year-old patient had a history of vitreoretinal surgery and transscleral-sutured posterior chamber intraocular lens implantation after complicated cataract surgery. He was referred to our department because of suture exposure. The best-corrected visual acuity was 20/2000 OD and 20/50 OS. We observed exposed PC9 sutures from both the nasal and temporal conjunctiva in the right eye. The patient showed appearance of scleromalacia in the same regions, so scleral flap surgery was not considered. Despite both tenoplasty and amniotic membrane transplant procedures, exposure could not be controlled. Instead, the patient received oral (buccal) mucosal graft transplant to the resistant exposure areas. A single layer of protective amniotic membrane was transplanted over the buccal mucosal graft. This method resulted in effective control of the exposed area. In conclusion, an oral mucosal graft can be used in many ocular pathologies that require conjunctival reconstruction because of the simplicity of tissue excision from the mucosa, allowing adequate tissue excision, durability of the obtained tissue, and ease of use. Our case report highlights that resistant transscleral-sutured posterior chamber intraocular lens suture exposure can be successfully managed with oral mucosal grafting.

Letter to the editor: Prospective analysis of STRATAFIX™ symmetric PDS plus suture for fascial closure in spinal surgery: a pilot study.

Spine surgery is essential for restoring alignment, stability, and function in patients with cervical spine injuries, especially when instability, pain, deformity, or progressive nerve damage is present. Effective wound closure is vital in these procedures, aiming to promote rapid healing, reduce infection risks, enable early mobilization, and ensure satisfactory cosmetic results. However, there is limited evidence on the optimal wound closure technique for posterior spine surgery, highlighting the need for innovative approaches. A study by Glener et al. evaluated the effectiveness of STRATAFIX™ Symmetric barbed sutures compared to traditional braided absorbable sutures in spinal surgery. In a randomized trial involving 20 patients, the STRATAFIX™ group demonstrated a shorter mean closure time and significantly fewer sutures used, though without a statistically significant reduction in closure time. No significant differences were observed in postoperative complications between the groups during a six-month follow-up. While the findings suggest potential cost savings and efficiency improvements with STRATAFIX™, the study's small sample size and short follow-up period limit its generalizability. Furthermore, AI-based models, such as the Xception deep learning model, show promise in improving suture training accuracy for medical students, which could enhance surgical outcomes and reduce complications. Despite the promising results, further research with larger sample sizes, extended follow-up periods, and multi-center trials is necessary to validate the effectiveness of barbed sutures like STRATAFIX™ in neurosurgery. The integration of AI in surgical training and continued exploration of innovative techniques are essential to advancing the field and optimizing patient care in spinal surgery.

Effectiveness of different appendiceal stump closure methods in laparoscopic appendectomy a network meta-analysis.

PURPOSE: Choosing the best stump closure method for laparoscopic appendectomy has been a debated issue, especially for patients with acute appendicitis. The lack of consensus in the literature and the diverse techniques available have prompted the need for a comprehensive evaluation to guide surgeons in selecting the most optimal appendiceal stump closure method. METHODS: A comprehensive search was conducted on multiple databases from inception until December 2023 to find relevant studies according to eligibility criteria. The primary outcome was the incidence of total complications. RESULTS: 25 studies with a total of 3308 patients were included in this study, overall complications did not reveal a significant advantage for any intervention (RR = 0.72, 95% CI: 0.53; 1.01), Superficial and deep infection risks were similar across all methods, Operative time was significantly longer with endoloop and Intracorporeal sutures (MD = 7.07, 95% CI: 3.28; 10.85) (MD = 26.1, 95% CI: 20.9; 31.29). CONCLUSIONS: There are no significant differences in overall complications among closure methods. However, Intracorporeal sutures and endoloop techniques were associated with extended operative durations.

Robotic purse-string suture technique for intracorporeal anastomosis using double-stapling technique in robotic resection of rectal and sigmoid colon cancer: a propensity score-matched analysis.

BACKGROUND: Robotic three-dimensional magnified visual effects and field of view stabilization have enabled precise surgical operations. Intracorporeal anastomosis in right-sided colorectal cancer surgery is expected to shorten operation times, avoid paralytic ileus, and shorten wound lengths; however, there are few reports of intracorporeal anvil fixation for intestinal anastomosis in left-sided colorectal cancer surgery. Herein, we introduce a simple, novel procedure for using robotic purse-string suture (RPSS) in intracorporeal anastomosis with the double-stapling technique in rectal and sigmoid cancer surgery and report short-term outcomes. METHODS: From September 2022 to April 2024, 105 consecutive patients underwent robotic surgery with double-stapling technique anastomosis for rectal or sigmoid colon cancer at our institution. Their data were retrospectively analyzed. Intracorporeal anastomosis with the double-stapling technique using RPSS was performed in 26 patients (the RPSS group), while the double-stapling technique anastomosis with extracorporeal anvil fixation was performed in 79 patients (the EC group). A 1:1 propensity score-matched analysis was performed (matching criteria: sex, age, body mass index (BMI), tumor location and tumor size) using a caliper 0.3. In the RPSS group, after tumor-specific or total mesorectal excision, specimens were extracted from the umbilical wound with simultaneous anvil placement in the body cavity. The oral colonic stump was robotically excised and robotically circumferentially stitched with 3-0 Prolene in all layers. After anvil insertion into the stump, the bowel wall of the colon was completely sewn onto the central rod of the anvil. Reconstructions were anastomosed using the double-stapling technique. RESULTS: The matched cohort contained 23 patients in each group. The RPSS group had significantly less bleeding than the EC group (p = 0.038). Super-low anterior resection (SLAR) in the RPSS group had shorter total operative times than those in the EC group (p = 0.045). The RPSS group experienced no perioperative complications greater than Clavien-Dindo grade III or any anastomosis-related complications. CONCLUSIONS: The RPSS technique can be performed safely without any anastomosis-related complications and reduces the total operative times in SLAR and blood loss through total robotic surgery. This may be a useful modality for robotic colorectal surgery.

Closing the internal opening with a rectal advancement flap increases the efficacy of mesenchymal stem cell injection for complex Crohn's disease anal fistulas.

BACKGROUND: The efficacy of injections of mesenchymal stem cells (MSC) for anal fistula treatment may be impaired by the persistence of stools passing into the fistula, causing bacterial contamination and a local inflammatory reaction. We aimed to compare remission rates between patients treated by MSC injection with simple sutures and those treated with a rectal advancement flap. METHODS: This single-center prospective study compared the first patients who underwent internal opening closure with sutures with the subsequent patients treated with a flap. Complete clinical remission was defined as complete closure of the external opening(s) without pain or discharge, and complete radiological remission was defined as a Magnifi-CD score of 0. RESULTS: We compared the first 42 patients who had sutures with the 20 subsequent patients who had an advancement flap. The median follow-up was 15.5 [8.8-24.9] months. The cumulative incidence of complete clinical response at M12 was 53.8% [38.1-69.6%] in the suture group versus 93.3% [77.4-100.0] in the flap group (p < 0.001). The Magnifi-CD score was 0 for 41.7% [25.5-59.2%]) of patients treated with sutures versus 72.7% [39.0-63.9%]) of patients treated with a flap (p = 0.093). Anal incontinence score did not differ between the two groups. Practicing an advancement flap was the only significant factor associated with complete clinical remission over time (adjusted HR [95% CI] of 2.6 [1.4-4.9], p = 0.003). CONCLUSIONS: Complete clinical remission rates following MSC injection are significantly higher after closure of the internal opening with a rectal flap than after closure with sutures, without consequences on anal continence.

Cerclage suture type to prevent pregnancy loss in women requiring a vaginal cervical cerclage: the C-STICH RCT.

Background: Second trimester miscarriage and preterm birth is a significant global problem. Surgical cervical cerclage is performed to prevent pregnancy loss and preterm birth. It utilises either a monofilament or braided suture. It is hypothesised that a braided material becomes colonised with pathogenic bacteria that causes vaginal dysbiosis, infection and cerclage failure. Objectives: The primary objective of the study was to examine the effectiveness of using a monofilament suture material as opposed to a braided suture material on pregnancy loss in women requiring a vaginal cervical cerclage. Design: Superiority open randomised controlled trial. Setting: Seventy-five maternity sites across the UK. Participants: Women experiencing a singleton pregnancy requiring a cervical cerclage. Interventions: Monofilament suture or braided suture. Main outcome measures: The primary outcome was pregnancy loss (miscarriage and perinatal mortality, including any stillbirth or neonatal death in the first week of life). Secondary outcomes included the core outcome set for preterm birth. Methods: Women were randomised on a 1 : 1 basis to monofilament or braided cerclage utilising a bespoke randomisation service with minimisation dependent on the site, indication for cerclage, intention to use progesterone and planned surgical technique. The inclusion criteria were three or more previous mid-trimester losses or preterm births, insertion of a cerclage in a previous pregnancy, a history of a mid-trimester loss or preterm birth with a shortened cervical length in the current pregnancy or in women who clinicians deemed at risk of preterm birth. The exclusion criteria were an emergency or rescue cerclage, age of < 18 years, being unable to give informed consent or the cerclage having to be placed abdominally. The original sample size was calculated based on a relative risk reduction of 41% from a pregnancy loss rate of 19% in the braided group to 11% in the monofilament group with 90% power and alpha at p = 0.05. The independent data monitoring committee noted a lower-than-anticipated pooled event rate within the trial and recommended an increase in sample size to 2050. The outcome data were collected using clinical record forms from the maternal and neonatal medical records and reported to Birmingham Clinical Trials Unit. Results: A total of 2049 women were randomised, after withdrawals and loss to follow-up, data on 1005 women in the monofilament group and 993 women in the braided group were included. The baseline demographics between the groups were similar. There was no evidence of a difference in pregnancy loss rates between the monofilament and braided groups (80/1003 vs. 75/993; adjusted risk ratio: 1.05, 95% confidence interval: 0.79 to 1.40; adjusted risk difference: 0.002, 95% confidence interval: -0.02 to 0.03). Limitations: The trial did not collect long-term paediatric outcomes. There were no safety concerns. Conclusions: There was no evidence of a difference in pregnancy loss between a monofilament suture and a braided suture. Future work: Long-term follow-up of neonates born within the C-STICH (cerclage suture type for an insufficient cervix and its effects on health outcomes) trial. Trial registration: This trial is registered as ISRCTN15373349.

Cervical cerclage is an operation performed in pregnancy to prevent miscarriage and preterm birth. A cervical cerclage is sometimes recommended in women who have had babies born prematurely before or who have had previous cervical surgery. A cerclage operation involves a stitch being inserted around the neck of the womb (cervix) to keep it closed during pregnancy and to prevent it opening prematurely. When performing the operation, the doctor can use different types of threads made of different materials. The threads used to perform the operation are called sutures. One suture type is a single strand or monofilament thread, and the other is a multifilament braided thread with lots of thin strands woven together. Some evidence has suggested that using a monofilament suture thread prevented pregnancy loss by preventing infection. Therefore, we performed a randomised controlled trial of the use of monofilament suture thread versus braided suture thread, aiming to reduce pregnancy loss in women who were having a cerclage as part of their routine care. The women consented to take part in the study and were randomly allocated to their cerclage performed with either a monofilament or braided suture thread; there was no other change to their planned pregnancy care. What happened in their pregnancy was recorded from their medical records and analysed. A total of 2049 women agreed to take part in the study and consented to the analysis of their pregnancy and neonatal outcomes. Cerclage suture type for an insufficient cervix and its effects on health outcomes showed that there was no difference in pregnancy loss between the two suture threads. There was decreased maternal sepsis and decreased chorioamnionitis (which is an infection inside the womb during labour) in the women who received a monofilament suture, which needs further investigation. Although more women who had a cerclage using the monofilament thread needed a small operation and an anaesthetic, often between 36 and 37 weeks, to remove the monofilament suture prior to a vaginal birth, there were no differences in the outcomes for their babies.

Adjustable flanged technique for secondary implantation of four-point scleral­fixated posterior chamber intraocular lenses using two parallel 6-0 polyglactin sutures.

OBJECTIVE: To assess the efficacy and safety of using the adjustable flanged technique for secondary implantation of four-point scleral­fixated posterior chamber intraocular lenses with two parallel 6-0 polyglactin sutures. METHODS: Two parallel 6-0 polyglactin sutures were passed separately through the two haptics on the horizontal line of the 4-haptic IOL. The four externalized sutures were then trimmed and cauterized to form flanges. The best corrected visual acuity, intraocular pressure, and complications in all patients were observed and recorded. RESULTS: The flanged technique using two parallel 6-0 polyglactin sutures was applied to 14 aphakic eyes. The average preoperative best corrected visual acuity was 1.00 ± 0.88 LogMAR (Snellen 20/200), which improved to 0.42 ± 0.38 LogMAR (Snellen 20/48) at the final follow-up (P = 0.004). None of the patients experienced vitreous hemorrhage, low intraocular pressure, or issues with exposed or broken sutures. CONCLUSION: The simplicity of the technique, along with its ability to accommodate adjustments post-implantation, allows for optimal positioning and reduces risks like IOL tilt or dislocation. Overall, this is a promising approach to secondary IOL implantation, with potential benefits for both patient outcomes and surgical efficiency.

Subcutaneous fixation model for complex stenting of recurrent laryngotracheal stenosis.

BACKGROUND: A straight silicone stent can be used to treat proximal benign tracheal stenosis in non-surgical candidates. However, stent migration is a common complication when placed at a particular location and can lead to major complications. This case series of laryngotracheal stenosis reports a fixation method for straight silicone stents in the subglottic trachea (Stage 3 of the McCaffrey classification). METHODS: The medical charts of these patients scheduled for straight silicone stent placement with suture fixation between 2014 and 2020 at the CHU UCL Namur Hospital (Belgium) were retrospectively reviewed. The procedure was performed using a rigid bronchoscope. Details of the procedure were obtained from medical records. RESULTS: This case series included six patients (males: 4, females: 2). The median patient age was 59 years. Two suture fixations were placed following previous silicone stent migration episodes, whereas the others were placed proactively to avoid this risk. All fixations were performed by the device Freka® Pexact II ENFIt®, originally developed for gastropexy in endoscopic gastrostomy. The sutures were subcutaneously buried. CONCLUSIONS: During the 6-month follow-up period, complications such as fixation issues and stent migration were reported despite the off-label use of the treatment. The straight silicone stent fixation technique used in this case series was simple and effective for securing the stent in upper benign tracheal stenosis.

[Clinical Efficacy of Anchor Suture Bridge Technique for Avulsion Fractures of the Posterior Cruciate Ligament Tibial Insertion Point in the Knee Joint]. / é”šé’‰ç¼çº¿æ¡¥æŠ€æœ¯å¯¹è†å ³èŠ‚åŽäº¤å‰éŸ§å¸¦èƒ«éª¨æ­¢ç‚¹æ’•è„±éª¨æŠ˜çš„ä¸´åºŠç–—æ•ˆ.

Objective: To investigate the clinical efficacy of the anchor suture bridge technique in treating avulsion fractures at the tibial insertion point of the posterior cruciate ligament (PCL) in the knee joint. Methods: In this study, we reviewed 80 patients with PCL tibial avulsion fractures treated using the anchor suture bridge technique in our department from February 2010 to December 2023. Follow-ups were conducted starting at 3 months post-surgery, then every 3 months until 12 months post-surgery. Clinical and follow-up data of each patient were analyzed. The Lysholm and Hospital for Special Surgery Knee-Rating Scale (HSS) scores of knee function before surgery and at the last follow-up were compared to assess the surgical treatment outcome. Results: The 80 patients were followed up for an average of (12.16±1.08) months post-surgery. Re-examination X-rays showed that all fractures had healed, with an average healing time of (3.66±0.51) months. All patients recovered well, with primary healing of surgical incisions and no complications such as neurovascular injury, skin necrosis, incision infection, fracture displacement, or ligament laxity. Postoperative knee Lysholm and HSS scores were significantly higher than preoperative scores. At the last follow-up, the Lysholm score increased from (46.30±6.10) preoperatively to (90.85±3.27), and the HSS score increased from (45.30±5.80) to (91.15±2.66), with statistically significant differences (P<0.025). Conclusion: The anchor suture bridge technique is effective in treating avulsion fractures of the PCL tibial insertion point in the knee joint. It has a high safety profile and leads to good postoperative knee function recovery, with no serious postoperative complications, demonstrating excellent clinical efficacy.

A modified open surgical revision technique for malfunctioning peritoneal dialysis catheter.

Backgrounds: The malfunction of peritoneal dialysis (PD) catheter is still an intractable problem. A modified open surgical revision technique with suturing fixation and without catheter removal for malfunctioning catheter was developed to evaluated the efficacy and safety between simultaneous catheter replacement technique.Methods: A total of 167 PD patients with malfunctioning catheter were retrospectively reviewed. For the salvage of PD catheters, patients underwent modified open surgical revision (group A) or simultaneous catheter replacement (group B). The baseline characteristics before operation, perioperative condition, complications and outcomes were compared between both groups.Results: Patients of group A showed significantly shorter operative time (67.4 ± 22.1 versus 82.8 ± 21.1 min, p = 0.009), less postoperative pain score within 24 h (median 0.0 versus 2.0, p < 0.001), quicker start of PD (1.06 ± 0.31 versus 1.89 ± 0.89 days, p < 0.001), shorter length of stay (9.89 ± 5.11 versus 12.55 ± 7.37 days, p = 0.020) than group B. In terms of complications, the incidence of recurred catheter malfunction in group A was significantly lower than those in group B (1/114 versus 12/53, p < 0.001). There were no significant differences in mechanical complications (bloody effluent, dialysate leakage, and hernia) and early peritonitis between the groups. The group A patients had a favorable catheter survival rate compared with group B (log-rank, p = 0.004).Conclusions: Our modified open surgical revision technique is a safe, simple and fast method, and offers a better outcome with minimal risk of recurrence of catheter malfunction without additional cost and equipment. This technique is worthy of clinical application.

Repair of Parastomal Hernias.

Parastomal hernias are an inevitable consequence of ostomy formation and their repairs remain a challenge to many surgeons. With multiple systems of classification and a multitude of techniques for hernia repair ranging from suture to mesh repair, the literature remains sparse with regards to the optimal method of repair. The authors describe the most commonly adopted techniques, discuss preventative measures, and review the current literature in the context of perioperative outcomes and hernia recurrence.

Suture reinforcement using a modified cyanoacrylate glue to prevent anastomotic leak in colorectal surgery: a prospective multicentre randomized trial : The Rectal Anastomotic seaL (ReAL) trial.

BACKGROUND: Anastomotic leakage (AL) is the most frequent life-threating complication following colorectal surgery. Several attempts have been made to prevent AL. This prospective, randomized, multicentre trial aimed to evaluate the safety and efficacy of nebulised modified cyanoacrylate in preventing AL after rectal surgery. METHODS: Patients submitted to colorectal surgery for carcinoma of the high-medium rectum across five high-volume centres between June 2021 and January 2023 entered the study and were randomized into group A (anastomotic reinforcement with cyanoacrylate) and group B (no reinforcement) and followed up for 30 days. Anastomotic reinforcement was performed via nebulisation of 1 mL of a modified cyanoacrylate glue. Preoperative features and intraoperative and postoperative results were recorded and compared. The study was registered at ClinicalTrials.gov (ID number NCT03941938). RESULTS: Out of 152 patients, 133 (control group, n = 72; cyanoacrylate group, n = 61) completed the follow-up. ALs were detected in nine patients (12.5%) in the control group (four grade B and five grade C) and in four patients (6.6%), in the cyanoacrylate group (three grade B and one grade C); however, despite this trend, the differences were not statistically significant (p = 0.36). However, Clavien-Dindo complications grade > 2 were significantly higher in the control group (12.5% vs. 3.3%, p = 0.04). No adverse effects related to the glue application were reported. CONCLUSION: The role of modified cyanoacrylate application in AL prevention remains unclear. However its use to seal colorectal anastomoses is safe and could help to reduce severe postoperative complications.

Modified pulley maneuver to guide surgical plane in minimally invasive liver resection.

INTRODUCTION: Achieving an adequate surgical plane through optimal traction is crucial for liver parenchymal transection in minimally invasive liver surgery (MILS). MILS is more technically demanding than open liver surgery because of limited instrument mobility and the inability to use the surgeon's hand, potentially leading to iatrogenic injuries. The Pulley maneuver using barbed sutures has been used for laparoscopic hepatectomy; however, the sutures are single-use and may pass through the liver parenchyma, making it uneconomical and inflexible. To address this, we developed a modified pulley maneuver using a barbed with a nonabsorbable polymer clip and metal clip for parenchymal transection in MILS. MATERIALS AND SURGICAL TECHNIQUE: Before liver transection, we prepared barbed sutures and attached nonabsorbable polymer and metal clips to the distal end. The metal clip prevented the nonabsorbable polymer clip from slipping, allowing one suture to be reused three times. Before liver transection, the suture was passed through the liver surface twice, with the clips to reduce iatrogenic damage. The sutures were anchored to the diaphragm or peritoneum for optimal liver traction. A laparoscopic or robotic grasper adjusted the suture tension for the appropriate transection plane. In open-pit-shaped resections, the liver is lifted ventrally for deeper access, whereas in wedge-shaped resections, it is elevated in the caudal view. The modified pulley maneuver provides stable liver traction. DISCUSSION: The modified pulley maneuver is an economical, simple, and feasible method for enabling stable liver traction, thereby enhancing the versatility and safety of liver parenchymal transection in MILS.

Securing skin grafts: A network meta-analysis.

BACKGROUND: Skin grafting is one of the most common procedures in plastic surgery. However, there are no defined guidelines for optimal fixation. The aim of this network meta-analysis (NMA) was to consolidate existing evidence by comparing various graft securing methods and determining the most effective approach for clinical practice. METHODS: An NMA was conducted using a predetermined protocol after searching several electronic databases from inception to October 2023 for studies examining skin grafting fixation outcomes in adults. RESULTS: A total of 27 studies were included in the analysis involving 1937 patients. Negative pressure wound therapy (NPWT) was the only method to significantly improve graft take percentages in comparison with the other modalities, whereas tie-over bolster (TOB) provided the worst results in take rates when examined as events. Fibrin glue (FIB) and TOB reduced hematoma and seroma rates when data were investigated in conjunction. CONCLUSIONS: NPWT appears to be the most effective for skin graft adherence as opposed to traditional techniques. Its cost-effectiveness remains unclear, as NPWT is a relatively costly intervention compared with other methods. FIB and TOB are methods that can serve as a method of reducing hematoma and seroma rates in patients at high risk of bleeding. LEVEL OF EVIDENCE: I.

Clinical and radiographic outcome of tension band suture fixation for displaced olecranon fractures.

BACKGROUND: Tension band wire fixation (TBW) is a well-described method for treating displaced olecranon fractures. Further surgery is often needed due to wound breakdown or prominent hardware. An all-suture technique has recently been described as an alternative to TBW but radiographic and clinical outcome are not well established. The aim of this single-center retrospective cohort study was to evaluate outcome after treatment with all-suture technique for simple displaced olecranon fractures. METHODS: A retrospective review of olecranon fractures in patients (> 18 years) treated for displaced olecranon fractures with tension band suture fixation (TBSF) between February and August 2019 was performed in our facility. Primary outcome was revision surgery, which was assessed four years after surgery. Clinical and radiographical follow-up was performed at two weeks, six weeks, three months and six months to assess union rate, fracture displacement, range of motion (ROM), Quick-DASH and Oxford Elbow Score. RESULTS: A total of 24 patients were included. Median age was 64 years [IQR:39-73], 9 patients were male and median ASA score was 2 [IQR:1-2]. 15 fractures were Mayo type 2 A and 9 type 2B with minor comminution. At four-year follow-up, three patients had died. None of the remaining 21 patients had undergone revision surgery. At six months, the median Quick-DASH and Oxford Elbow Score were 2.3 [IQR:0-4.5] and 47 [IQR:46-48], respectively. Median elbow extension and flexion deficits were 0° [IQR:0-2.25] and 0° [IQR:0-0], respectively. Radiographic union was achieved in all patients. In two cases radiographic loss of reduction and malunion was observed but both patients were asymptomatic and had no functional deficits. One patient refractured the elbow due to a second trauma and was reoperated. CONCLUSIONS: TBSF is a promising technique for Mayo type 2 A and 2B fractures with minor comminution. There were no revision surgeries within the first four years. We found good functional outcomes and a high union rate.

Wound closure techniques for spinoplastic surgery: a review of the literature.

PURPOSE: The approach to skin closure in spinal surgery is dependent on surgeon preference and experience. Wound complications, including dehiscence and surgical site infection (SSI), are common following spine surgery. The authors reviewed various wound closure techniques employed in spinal surgery. METHODS: A systematic review was conducted to identify articles comparing wound closure techniques after posterior spinal surgery. Articles that employed experimental or observational cohort study designs and reported rates of SSI, dehiscence, or scarring following spinal surgery were included. RESULTS: Eight studies examining closure techniques of the skin were identified: five retrospective cohort studies and three randomized-controlled trials. No differences in the incidence of SSI were reported based on suture technique, although staples were associated with higher SSI rates in single level spinal fusion, and barbed suture resulted in decreased wound complications. The use of intracutaneous sutures was associated with a higher incidence of wound dehiscence when compared to tension-relieving far-near near-far suture (FNS) and far-near near-far interrupted point (FNP) sutures. However, the latter two also resulted in the highest rates of delayed wound healing (i.e., time to fully heal). Modified Allgöwer-Donati suture (MADS) resulted in smaller scar area when compared to vertical mattress suture. CONCLUSION: Significant differences exist in wound healing when comparing suture techniques in spinal surgery. Surgical staples allow for faster closing time, but are also associated with higher wound complications. Intracutaneous sutures appear to have higher rates of dehiscence compared to vertical mattress suture but display faster wound healing. Future studies are necessary to elucidate contributory factors, including local ischemia and changes in tensile forces. LEVEL OF EVIDENCE: Level IV.

Prospective analysis of STRATAFIX™ symmetric PDS plus suture for fascial closure in spinal surgery: a pilot study.

Wound closure is an integral part of every spinal procedure. Effective and secure wound closure is paramount in the prevention of infection, wound dehiscence and the preservation of cosmesis. Barbed suture technologies such as STRATAFIX™ Symmetric have been studied and are used in a variety of specialties, including obstetrics and orthopedic surgery, but is underutilized in neurosurgery. This study aims to assess the time and rate of closure using STRATAFIX™ Symmetric technology for fascial closure and compare this method to the more traditionally used method of fascial closure using braided absorbable sutures below the epidermis. 20 patients were recruited for the study. 10 patients underwent fascial approximation with braided absorbable sutures and definitive fascial closure with STRATAFIX™ Symmetric. In the control group, fascial closure was completed entirely with interrupted braided absorbable stitches. Patients assigned to STRATAFIX™ Symmetric group had shorter mean time for fascial closure, faster rate of average fascial closure, and lower number of total sutures used. The use of barbed suture technology such as STRATAFIX™ Symmetric may reduce the time to closure in thoracolumbar spine surgery without increasing the risk of adverse events. This pilot study forms the framework for a larger randomized, controlled trial appropriately powered for such an analysis.
