Knee laxity after anterior tibial eminence fracture in children: A 35-case series. Orthop Traumatol Surg Res 2023; 109:103533. [PMID: 36572379 DOI: 10.1016/j.otsr.2022.103533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 10/19/2022] [Accepted: 11/03/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Anterior tibial eminence (ATE) fractures are characterized by avulsion of the anterior cruciate ligament insertion. The aim of our study was to evaluate the long-term incidence of laxity and instability in the aftermath of these fractures. The secondary objective was to identify factors for instability. HYPOTHESIS ATE fracture in children is responsible for laxity and instability in the medium and long term. MATERIAL AND METHODS This retrospective, single-center study included 35 isolated fractures of the tibial intercondylar eminence during skeletal growth between January 2006 and January 2020. Analysis comprised demographics, laxity measured by GNRB™, range of motion and IKDC and Lysholm scores. Clinical reassessment was performed in 24 patients, the other 11 being interviewed by telephone. RESULTS Mean laxity on GNRB™ was 1.46mm, and 3 patients had>3mm differential with respect to the healthy knee. Mean IKDC score was 92.2 and mean Lysholm score 93.1. Four patients showed instability, 2 of whom required surgical management. There was no significant difference in occurrence of laxity according to fracture type or reduction quality. Mean follow-up was 5.9years (range, 1.1-14.8). DISCUSSION Our clinical and functional results were in accordance with the literature. The long-term clinical results were satisfactory. ATE fractures require long-term follow-up to screen for instability and laxity on GNRB™. LEVEL OF EVIDENCE IV, retrospective study.

Abstract
ABSTRACT The purpose of this study was to introduce a modified suture technique and to compare its effects on skin scar formation with 2 traditional suture methods: simple interrupted suture (SIS) and vertical mattress suture (VMS). Three groups of healthy adult female Sprague-Dawley rats were selected (6 replicates in each group), and the full-thickness skin of 5 cm × 0.2 cm was cut off on the back of the rats after anesthesia. The wounds were then sutured using 1 of the 3 methods for each group: SIS, VMS, and a newly introduced modified vertical mattress suture (M-VMS) technique with the needle reinsertion at the exit point. A traction device was installed on the back of the rats to achieve high tension wounds. The tensile distance was increased by 1 mm every day for 20 days. After 20 days of healing, the hematoxylin-eosin staining method was used for observation of scar morphology. The collagen production rate was measured by Masson staining, and the type I collagen and type III collagen were detected by the immunofluorescence method. Immunohistochemical staining was used to detect the expression of myofibroblast marker α-smooth muscle actin, and real-time quantitative polymerase chain reaction and Western blot techniques were used to detect the expressions of transforming growth factors TGFβ1, TGFβ2, and TGFβ3 to understand the mechanisms of scar formation. Results showed that the quantity and density of collagen fibers were both lower in the M-VMS group than in the other 2 groups. Immunofluorescence results showed that type I collagen was significantly lower, whereas type III collagen was significantly higher in the M-VMS group than in the other 2 groups. The expressions of α-smooth muscle actin and TGFβ1 both were lower in the M-VMS group than in the other 2 groups. The expression of TGFβ2 and TGFβ3 had no obvious difference among the 3 groups. For wounds under high tension, compared with SIS and VMS methods, the M-VMS technique we proposed can reduce scar formation due to the reduction of collagen formation, myofibroblast expression, and TGFβ1 expression.

Abstract
PURPOSE To present an electrocoagulation fixation technique for one-piece intraocular lens (IOL) scleral flapless fixation with sutures without knots. METHODS First of all, after repeated tests and comparisons, we chose 8-0 polypropylene suture as the material for electrocoagulation fixation of one-piece IOL haptics because of its proper elasticity and size. A transscleral tunnel puncture at the pars plana was performed using an arc-shaped needle with 8-0 polypropylene suture. The suture was subsequently guided out of the corneal incision by a 1-mL syringe needle and then guided by the needle into the inferior haptics of the IOL. The suture was cut off and heated into a shape of a probe with a spherical tip using a monopolar coagulation device to prevent slippage from the haptics. RESULTS In the end, 10 eyes underwent our new surgical procedures, and the average operation time was 42.5 ± 12.4 minutes. At the 6-month follow-up, seven of 10 eyes achieved significant vision improvement and nine of 10 kept the implanted one-piece IOL stable in the ciliary sulcus. No serious intraoperative/postoperative complications were observed. CONCLUSION The electrocoagulation fixation was a safe and effective alternative technique for previously implanted one-piece IOL scleral flapless fixation with sutures without knots.

Abstract
PURPOSE Haptic repositioning during flanged intraocular lens (IOL) fixation can be difficult, and the haptic requiring repositioning may be at increased risk of excessive bending or breakage. This study aimed to report double-needle haptic repositioning technique outcomes for the aforementioned difficulty during flanged IOL fixation. METHODS This retrospective case series included seven eyes requiring haptic repositioning during flanged IOL fixation. The method features reinsertion of an already externalized haptic into the needle lumen followed by a needle-haptic complex internalized through the original tract into the eyeball. Thus, an adequate configuration for contralateral haptic can be achieved for insertion into the needle lumen to create a double-needle condition before both haptics are successfully externalized. RESULTS The median follow-up duration was 24 months (range, 4-24 months). Postoperatively, the IOL was well-centered, and corrected distance visual acuity improved from 20/320 (20/4,000-20/70) to 20/50 (20/250-20/20). No intraoperative or postoperative complications were noted. CONCLUSION The technique produced encouraging results in patients undergoing haptic repositioning during flanged IOL fixation. This technique could potentially reduce haptic overbending risk and facilitate haptic adjustment. Further studies are needed to confirm the feasibility of the technique.

Abstract
OBJECTIVE To describe and evaluate the surgical outcomes of multilayered closure of persistent tracheocutaneous fistulae (TCF) in patients with challenged wound healing. METHODS A retrospective chart review of all patients who underwent closure of TCF by the senior author between October 2011 and December 2021 was performed. Age, body mass index (BMI), time between decannulation and TCF repair, medical comorbidities, procedure duration, length of hospitalization, and postoperative complications were recorded. The primary outcomes were closure of the fistula, postoperative subcutaneous emphysema, pneumomediastinum, pneumothorax, wound infection, or breakdown. Outcomes of patients with and without challenged wound healing were compared. RESULTS Thirty-five patients who underwent TCF repair during the study period were identified. The mean age and BMI were 62.9 years and 28.43 respectively. Twenty-six (74%) patients met criteria for challenged wound healing at the time of the TCF repair. There was 1 (3.84%) minor complication in the challenged wound healing group and none (0%) in the control group (P = 1.00). No patients experienced wound breakdown or air leak noted on exam or chest radiography. CONCLUSION Multilayered closure of persistent tracheocutaneous fistulae is a simple technique which is safe and effective even in patients with challenged wound healing.

Abstract
PURPOSE The purpose of this study was to summarize the misdiagnosis and treatment of corneal complications associated with suture exposure in cases of buried-suture double-eyelid blepharoplasty. METHODS This study retrospectively analyzed 14 patients with palpebral conjunctival and corneal complications due to suture exposure after buried-suture double-eyelid blepharoplasty at the First Affiliated Hospital of Harbin Medical University from January 2020 to July 2022. The patients' clinical symptoms included photophobia, lacrimation, pain, foreign body sensation, swelling of the eyelids, conjunctival hyperemia, secretion, etc. We recorded the patient's sex, age, surgical method, length of exposed suture, suture type, number of double-eyelid surgeries, surgical site, timepoint when eye discomfort occurred, misdiagnosed disease and treatment. RESULTS Three patients were misdiagnosed with dry eye, nine patients were misdiagnosed with viral keratitis, and two patients were misdiagnosed with allergic conjunctivitis. All 14 patients had manifestations of photophobia, lacrimation, pain, foreign body sensation and conjunctival hyperemia. Eight patients had manifestations of swelling of the eyelids. Five patients had manifestations of eye secretions. There were 8 patients with corneal epithelial injuries and 6 patients with corneal ulcers. All patients underwent suture removal without further progression. Ten patients were treated with artificial tears, and 4 patients were treated with calf serum deproteinized gel after suture removal. CONCLUSION If there is postoperative eye discomfort caused by eyelid and corneal complications in patients after buried-suture double-eyelid blepharoplasty, clinicians should carefully check whether there is suture exposure and determine the cause in a timely manner. Suture removal is the best way to treat this complication. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
INTRODUCTION In the absence of consensus on the optimal approach to renorrhaphy in partial nephrectomy, this systematic review aims to assess the various renorrhaphy techniques and their impact on surgical outcomes. EVIDENCE ACQUISITION A systematic review of the literature was performed in March 2022, using PubMed and Scopus, without time restrictions and research filters for studies investigating renorrhaphy techniques in partial nephrectomy. Studies providing sufficient details on renorrhaphy techniques and their outcomes during minimally invasive partial nephrectomy (PN) were included in this analysis. EVIDENCE SYNTHESIS Thirty-one studies with 5720 patients were included in the analysis. In most studies, tumor diameter was <4 cm. RENAL and PADUA scores as well as tumor locations were heterogeneous between the studies. The results of the use of hemostatic agents were conflicting among different studies with limited evidence regarding the benefits of its routine use in partial nephrectomy. The use of barbed and running sutures was associated with a reduced warm ischemia time. While some studies showed a decreased warm ischemia time when omitting cortical renorrhaphy, others found that it may lead to higher incidence of minor complications without any significant improvement in other outcomes. CONCLUSIONS There is ongoing research to determine the optimal approach to renorrhaphy. The current evidence on the routine use of hemostatic agents is limited. The use of certain techniques such as barbed sutures, sliding clips and running sutures reduced the warm ischemia time. The omission of cortical renorrhaphy is still controversial.

Effect of barbed versus standard sutures on wound complications in total knee arthroplasty: A meta-analysis. Int Wound J 2023; 20:4130-4137. [PMID: 37519132 PMCID: PMC10681399 DOI: 10.1111/iwj.14307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 06/26/2023] [Accepted: 06/28/2023] [Indexed: 08/01/2023] Open
Abstract
A barbed suture has been demonstrated to be effective in shortening the stitching time and improving the aesthetic appearance of the stitches during the entire knee replacement. However, no meta-analyses have been conducted specifically to evaluate the effect of the barbed thread on wound complications relative to the conventional suture. A comprehensive search of the PubMed database, the Embase database, the Cochrane Library and the Web of Science was performed to obtain search data up to June 2023, and only randomised controlled trials were included in this meta-analysis. We used Review Manager 5.3 for data synthesis and analysis. This meta-analysis included eight studies. It was found that the use of barbed sutures did not improve the incidence of the disease, the infection of the wound, the closure of the abscess and the injury. However, because of the limited sample size of the randomised controlled trials for this meta-analysis, the data should be handled with caution. More high-quality, large-sample studies will be required to confirm the results.

Comparison of three different intraocular lens implantation techniques in the absence of capsular support: sutured scleral, haptic flanged intrascleral, and four flanged intrascleral fixations. Int Ophthalmol 2023; 43:5045-5053.

Abstract
INTRODUCTION After lens extraction, if the capsular bag insufficiency occurs, there are different IOL implantation techniques. IOL implantation in the posterior chamber is safer in eyes with low endothelial cell count, peripheral anterior synechiae, shallow anterior chamber, and glaucoma. Alternative approaches for scleral fixation techniques, both with and without sutures, continue to undergo development. In this study, we aimed to compare the postoperative outcomes of the sutured scleral fixation (SSF), haptic flanged intrascleral fixation (HFISF) and four flanged intrascleral fixation (FFISF) IOL implantation techniques in eyes with the absence of capsular support. MATERIALS AND METHODS A hundred and thirty-seven aphakic eyes with the absence of capsular support were included in the study. The patients were divided into three groups: group 1-SSF, group 2-HFISF (Yamane technique), and group 3-FFISF. Surgical time in minutes, preoperative and postoperative parameters such as best corrected visual acuity (BCVA), corneal astigmatism, lenticular astigmatism, intraocular pressure (IOP), specular microscopy, central macular thickness (CMT) were recorded. Pseudophacodonesis was assessed at 6 months postoperatively using a slit lamp, and early and late complications were recorded. RESULTS Of the 137 eyes, 69 eyes were included in the SSF group, 41 eyes in the HFISF group, and 27 eyes in the FFISF group. No statistically significant differences were observed among the three groups in terms of age, gender, preoperative mean BCVA, corneal astigmatism, IOP, endothelial cell density, and CMT. It was observed that the mean BCVA significantly improved compared to the preoperative visual acuity in all three groups. Postoperative lenticular astigmatism, pseudophacodonesis score, percentage of the endothelial cell loss were found to be higher in FFISF groups. The surgical time was found to be shorter in the HFISF group. IOL decentration was observed in 1.44% of the SSF group and 7.40% of the FFISF group. Cystoid macular edema was observed in 5.79% of the SSF group, 4.87% of the HFISF group, and 7.40% of the FFISF group. Retinal detachment was observed in 1.44% of the SSF group and 7.31% of the HFISF group. CONCLUSIONS The optimal technique for treating aphakia without capsular support remains uncertain. Surgeons are tasked with a complex decision, aiming for both excellent vision and minimal risk. This decision is based on their expertise, the distinctive ocular condition of the patient, and the availability of essential operating room equipment. In this study, the following findings were observed: in the HFISF technique, the average surgical time was found to be shorter, the SSF technique demonstrated greater stability in terms of astigmatism and pseudophacodonesis and the FFISF technique was recognized for its relatively straightforward application method. It is important to note that the three IOL implantation techniques yielded comparable outcomes in terms of postoperative BCVA, as well as early and late complications.

Abstract
BACKGROUND Conventionally, management of involutional entropion involves correcting both vertical and horizontal laxity, however the optimal surgical approach is debated. OBJECTIVE To compare the recurrence rate of horizontal lower eyelid shortening alone with combined surgical approaches for correction of involutional lower eyelid entropion. METHODS AND MATERIAL A retrospective, comparative, consecutive case series of patients undergoing surgery for involutional lower eyelid entropion with both horizontal and vertical laxity. Patients were categorized based on the procedure as: Group 1, horizontal shortening alone, Group 2, horizontal shortening with everting sutures), and Group 3, horizontal shortening with retractor plication. RESULTS Of the 249 procedures (31 bilateral) performed on 218 patients, 54 (22%) involved horizontal eyelid shortening alone (Group 1), while 80 (32%) had this combined with everting sutures (Group 2), and 115 (46%) with retractor plication (Group 3). The anatomical success rates for Groups 1, 2, and 3 were 93, 94, and 90% (P = 0.69), respectively. Similarly, reported symptom improvements were 94, 93, and 93% for these groups (P = 0.91). After an average follow-up of 15.7 months (median 10; range 6-81), Group 1 (eyelid shortening alone) had a 7% (4/54) recurrence, compared to 8% (16/195) in Groups 2 and 3 (combined procedures) (P = 1.0). Complications were minor, with no significant difference between groups. CONCLUSION Eyelid shortening alone appears to be as effective as combined techniques for involutional entropion with both horizontal and vertical eyelid laxity. Nevertheless, procedure selection should consider primary pathogenic factors.

Abstract
OBJECTIVE To evaluate the efficacy of three jaw adventitia holding (TADH) microclamps in end-to-end microvascular anastomosis. BACKGROUND Acland clamps, though highly efficacious, require a steep learning curve and are associated with complications such as back walling and incomplete bites. METHODS A single center, parallel group, 30-patient randomized clinical trial was conducted with a 1:1 allocation ratio in Acland and TADH microclamp groups. Primary outcome was time taken for microvascular anastomosis in terms of arterial and venous clamping and suturing time. Secondary outcomes included ease of use, need for clamp flipping and adventitia trimming, and need for assistance and flap survival. RESULTS TADH microclamps were found to be beneficial when compared to Acland microclamps in end-to-end microvascular anastomosis, in terms of artery clamp time (19.07 ± 3.751 min, 95% CI 10.058-17.942, p < 0.001), artery suture time (15.87 ± 3.357 min, 95% CI 10.660-17.206, p < 0.001), vein clamp time (21.50 ± 3.849 min, 95% CI 12.131-19.469, p < 0.001), and vein suture time (16.58 ± 3.147 min, 95% CI 13.232-20.368, p < 0.001). The TADH microclamps did not require flipping to enable suturing of the posterior walls of the vessel. Statistically significant difference was found in surgeon-reported ease of use with TADH microclamps (Chi-square value 9.867, p < 0.001). Statistically significant difference was found in relation to the need for assistance with TADH microclamps (Chi-square value 19.286, p < 0.001). CONCLUSION This study found TADH microclamps to be faster, easier to use, and clinically efficacious in reducing the anastomosis time compared to those of the Acland clamps.

Abstract
PURPOSE We compared 2 suturing techniques for reattachment of the flexor digitorum profundus (FDP) via all-suture anchor. METHODS We used fresh, matched-pair, cadaveric hands. We disarticulated the fingers at the proximal interphalangeal joints, preserving the proximal FDP. We released the FDPs at their distal insertion and placed an all-suture, 1.0-mm anchor at the center of each FDP footprint. Each anchor's sutures were used to reattach each FDP using 1 of 2 techniques: group H (n = 14) via horizontal mattress; group H + K (n = 12) via horizontal mattress with knots thrown and, with each suture tail, 3 proximal, running-locking, Krackow-type passes on the radial and ulnar FDP sides with the suture ends tied together. We excluded 2 specimens from the H + K group because of improper anchor placement. All other fingers in both groups were individually mounted in an MTS machine for FDP loading in the following sequence for 500 cycles each: (1) to 15 N to simulate passive motion forces; (2) to 19 N for short-arc active motion forces; and (3) to 28 N for full active motion forces. Specimens that had not failed during cyclic testing were then loaded to failure. We measured FDP-to-bone gapping via a digital transducer. We defined failure as >3-mm gapping. RESULTS The H + K group had significantly less gapping during cyclic loading up to 19 N and significantly higher load to failure. The H + K group failed exclusively at the anchor-bone level; the H group failed mostly by suture-tendon pullout. CONCLUSIONS The H + K group performed significantly better regarding cyclic and load-to-failure testing after FDP reattachment. CLINICAL RELEVANCE The H + K technique combines the benefits of horizontal-mattress tendon-to-bone apposition and Krackow-tendon locking. It converts the point of failure to the bone level rather than the suture-tendon level.

Abstract
PURPOSE To describe results in two cases of a dislocated silicone plate haptic intraocular lens managed with vitrectomy and repositioning with scleral suture fixation. METHODS Small case series. RESULTS Two patients presenting with dislocated silicone plate haptic intraocular lens underwent a 23-gauge vitrectomy with a "handshake" maneuver to pass a 9-0 prolene suture through the positioning holes to allow scleral fixation. Best-corrected visual acuity was returned to predislocation Level 2 and 8 months after the vitrectomy. CONCLUSION Silicone plate haptic intraocular lens can be managed with scleral suture fixation using this adapted technique, avoiding removal and exchange techniques. These are the first reported cases of silicone plate haptic intraocular lens managed with scleral suture repositioning.

Abstract
BACKGROUND Stapled vs handsewn methods of bowel anastomosis have been extensively studied, however, no study has compared the handsewn vs stapled technique of closing the common enterotomy. Anecdotal concerns of higher leak rates due to crossing staple lines has led some to prefer a handsewn technique for closing the common enterotomy. METHODS Patients undergoing stapled side-to-side enteroenteric and enterocolonic anastomoses in both emergent and elective settings at 1 tertiary center from 2016 to 2020 were studied. 758 patients were included. They were divided into 2 cohorts: Stapled-Stapled (SS) and Stapled-Handsewn (SH) depending on the fashion in which their stapled common enterotomy was closed. Association of anastomotic leak rate overall, in the emergent vs elective setting, and within enteroenteric and enterocolonic anastomotic subgroups was evaluated with both univariate and multivariate analysis. Association with the closure technique, mortality and average operative time was also compared. RESULTS Multivariate analysis overall leak rates (SS 5.9% vs SH 3.7%, P = .23) and enteroenteric leak rates (SS 2.9 vs SH 4.1, P = .52) were similar between cohorts. Operative times were significantly shorter in the SS cohort (SS 121.8 min vs SH 138.1 min, P = .049), with a difference of 16.3 min on average. No difference in mortality was seen. DISCUSSION The SH and SS result in similar anastomotic leak rates overall, and the SS technique is significantly faster than the SH technique. We therefore consider the SS technique to be an acceptable, and in the emergent setting, potentially preferred method of anastomotic technique.

Abstract
BACKGROUND There is no level 1a evidence testing quilting suture (QS) technique after mastectomy on wound outcomes. The aim of this systematic review and meta-analysis evaluates QS and association with surgical site occurrences as compared to conventional closure (CC) for mastectomy. METHODS MEDLINE, PubMed, and Cochrane Library were systematically searched to include adult women with breast cancer undergoing mastectomy. The primary endpoint was postoperative seroma rate. Secondary endpoints included rates of hematoma, surgical site infection (SSI), and flap necrosis. The Mantel-Haenszel method with random-effects model was used for meta-analysis. Number needed to treat was calculated to assess clinical relevance of statistical findings. RESULTS Thirteen studies totaling 1748 patients (870 QS and 878 CC) were included. Seroma rates were statistically significantly lower in patients with QS (OR [95%CI] = .32 [.18, .57]; P < .0001) than CC. Hematoma rates (OR [95%CI] = 1.07 [.52, 2.20]; P = .85), SSI rates (OR [95%CI] = .93 [.61, 1.41]; P = .73), and flap necrosis rates (OR [95%CI] = .61 [.30, 1.23]; P = .17) did not significantly vary between QS and CC. CONCLUSION This meta-analysis found that QS was associated with significantly decreased seroma rates when compared to CC in patients undergoing mastectomy for cancer. However, improvement in seroma rates did not translate into a difference in hematoma, SSI, or flap necrosis rates.

A Modified Double-Eyelid Blepharoplasty: Tarsus Linkage Mechanism. Aesthetic Plast Surg 2023; 47:2440-2446. [PMID: 37386262 PMCID: PMC10784336 DOI: 10.1007/s00266-023-03444-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 05/27/2023] [Indexed: 07/01/2023]
Abstract
BACKGROUND Double-eyelid blepharoplasty is the most popular plastic surgery in East Asia. The incisional methods are divided into two schools. The traditional method produces a stable eyelid, but will leave a postoperative scar. The other is represented by "Park," creating dynamic double-eyelid technology. Its advantage is that there is only mild scarring, but its disadvantages are asymmetry, corneal exposure, and loss of the palpebral furrow. Due to these various complications, we here propose an improved incisional blepharoplasty with the tarsus linkage mechanism. METHODS This work covers 482 patients who underwent surgery from March 2018 to March 2022. All patients completed 6 months of postoperative follow-up. The basic procedure described here involves removing the pre-tarsal tissue without completely incising the orbicularis and suturing the orbicularis and the tarsus into a unit. This connection provides a more robust and stable eyelid adhesion. RESULTS As reported by physicians, 412 patients (85.5%) had satisfactory results, 69 patients (14.3%) had somewhat satisfactory results, and 1 patient (0.2%) had unsatisfactory results. As reported by the patients, 424 patients (88.0%) were satisfied, 57 patients (11.8%) were somewhat satisfied, and 1 patient (0.2%) was unsatisfied. CONCLUSION This study proposes a modified double-eyelid blepharoplasty with the tarsus linkage mechanism. It is suitable for most primary eye cases, particularly in patients with lax upper lid skin and high levels of upper orbital fat.

Abstract
There is currently no consensus on the treatment of median sternotomy patients presenting secondarily with deep sternal wound infection or symptomatic sternal nonunion. We have developed a novel approach to sternal bone fixation when concerns for open wounds or microbial colonization preclude the use of permanent hardware placement: (1) sternal closure with absorbable interosseous monocortical horizontal mattress sutures followed by (2) multilayered soft tissue closure with pectoralis major advancement or turnover flaps. Benefits of this technique include: closure of retrosternal dead-space, tension offloading of the soft tissue closure, repair of transverse sternal fractures, and preservation of internal mammary artery (IMA) perforators for potential pectoralis turnover flaps. In our early experience, this technique has been successful at promoting functional sternal union - even in secondary closure of high-risk patients contraindicated for permanent hardware placement.

Abstract
PURPOSE To optimize the pterygium management by delineating the role of sutureless, glueless conjunctival graft. MATERIALS AND METHODS This was a prospective cohort study carried out at the Centre hospitalier universitaire de Cocody between October 1st, 2021 and March 31st, 2022. It analyzed a series of 36 cases of stage I, II and III pterygium by Cornand's classification, who underwent surgery by a sutureless conjunctival graft technique without biological glue. RESULTS Demographically, 33.3% of our study population were between 30 and 40 years of age, with a mean of 47.86 years. The patients showed a female preponderance, 53%, with a male:female ratio of 0.89. At the clinical level, 75% of our population presented for ocular redness, 84% had a nasal pterygium, and 75% were stage 2. In terms of postoperative course and appearance, we observed 80.55% graft stability, 5.56% graft retraction, 2.78% graft displacement, and 11.11% graft loss. At the conclusion of follow-up, we noted an 8.33% recurrence rate. DISCUSSION The use of intraoperative blood ensures patient safety and postoperative comfort. This technique demonstrates satisfactory results with primary, nasal pterygia. CONCLUSION Conjunctival autograft without sutures or biological glue might be a very promising surgical alternative in the surgical treatment of pterygium.

Abstract
PURPOSE To present the flattened flanged polypropylene suture technique developed to obtain round and stable pupils in patients with iridodialysis. METHODS After performing a fornix-based conjunctival peritomy, a flange was created at the tip of a 6.0 polypropylene suture by cautery. In the quadrant of iridodialysis, an ultrathin 30-gauge needle was inserted into the sclera at a distance of 2 mm from the limbus and advanced 1.5 mm intrasclerally, parallel to the limbus. The needle was directed radially into the eye and easily passed through the edge of the peripheral iris. The polypropylene suture was pushed into the lumen of the needle with the help of forceps. After the needle was externalized, the tip of the suture was flanged by cautery, and the flange was immediately flattened using a needle holder. RESULTS Six eyes of six patients with iridodialysis were enrolled in this study. Postoperatively, the irises remained well positioned and the pupils became round in all eyes. None of the patients developed suture erosion, suture loosening or rupture, hyphema, hypotony, chronic iridocyclitis, and angle closure. CONCLUSION The present technique provides a minimally invasive surgery and robust iris fixation without the need to create a scleral flap, groove, or pocket.

Abstract
PURPOSE To introduce a novel technique for small-incision levator resection in ptosis surgery and evaluate its efficacy in a pilot study among patients affected by congenital or aponeurotic ptosis. METHODS We prospectively enrolled congenital and aponeurotic ptosis patients if their levator function was not poor (≥5 mm) from June 2021 through October 2022. Surgical technique involved a 1-cm lid crease incision, minimal dissection, and creating a loop passing through the tarsus and levator aponeurosis. Success was defined as postoperative MRD-1 ≥3 mm and inter-eyelid MRD-1 difference ≤1 mm. Eyelid contour quality was scored excellent, good, fair, and poor according to its curvature and symmetry. RESULTS Sixty-seven eyes (35 congenital and 32 aponeurotic) were included in the study. Mean age was 34±19 years (range, 5-79 years). Mean preoperative levator function and levator resection amount were 9.53 mm and 8.39 mm in the congenital group and 12.34 mm and 4.15 mm in the aponeurotic group, respectively. Mean pre- and postoperative MRD-1 was 1.61 mm and 3.27 mm respectively (P<0.001). The overall success rate was 82.1% (95% C.I: 71.7-89.8%); the result was failure in 12 cases, of which 11 had under-correction. Preoperative MRD-1 was correlated with a success rate (P=0.017). CONCLUSION The described technique shows non-inferior results to the previously described surgical methods and also it shows very good lid contour outcome and minimal lag. The findings suggest that the double mattress single suture technique can be used in both congenital and aponeurotic ptosis.

Comparing the biomechanical properties of conventional suture and all-suture anchors using patient-specific and realistic osteoporotic and non-osteoporotic phantom using 3D printing. Sci Rep 2023; 13:20976.

Abstract
Conventional suture anchors (CAs) and all-suture anchors (ASAs) are used for rotator cuff repair. Pull-out strength (POS) is an important factor that affects surgical outcomes. While the fixation mechanism differs between the anchor types and relies on the quality, few studies have compared biomechanical properties of anchors based on bone quality. This study aimed to compare the biomechanical properties of anchors using osteoporotic bone (OB) and non-osteoporotic bone (NOB) simulators. Humerus simulators were fabricated using fused deposition modeling of 3D printing and acrylonitrile butadiene styrene adjusting the thickness of cortical bone and density of cancellous bone based on CT images. Cyclic loading from 10 to 50 N, 10 to 100 N, and 10 to 150 N for 10 cycles was clinically determined at each anchor because the supraspinatus generates a force of 67-125 N in daily activities of normal control. After cyclic loading, the anchor was extruded at a load of 5 mm/min. Displacement, POS, and stiffness were measured. In OB simulators, CAs revealed bigger gap displacement than ASAs with cyclic loading of 10-150 N. ASA showed higher values for POS and stiffness. In NOB simulators, ASAs revealed bigger gap displacement than CAs with cyclic loading of 10-150 N. ASA showed higher values for POS and CA showed higher values for stiffness. POS of anchors depends on anchors 'displacement and bone stiffness. In conclusion, ASA demonstrated better biomechanical performance than CA in terms of stability under cyclic loading and stiffness with similar POS in OB.

Abstract
BACKGROUND Arthroscopic repair is a promising, minimally invasive surgical technique for patients with Palmer type 1B peripheral triangular fibrocartilage complex (TFCC) tears. Although several arthroscopic techniques are effective for repairing Palmer type 1B TFCC tears, some shortcomings remain. So, we report an arthroscopic repair technique for the treatment of Palmer type 1B Atzei class 1 TFCC tears using an intracapsular suture: an outside-in transfer all-inside repair. METHODS A retrospective analysis of 38 Palmer type 1B TFCC injury patients admitted to our hospital were randomly divided into 2 groups. The group A was sutured from the outside to the inside, with a total of 21 cases; the group B was sutured with the new arthroscopic repair technique, with a total of 17 cases. Observe and compare the VAS scores and modified Mayo wrist function scores of all patients before 3, and 6 months after the operation and evaluate the incidence of thread knots in patients with different treatment methods. The methodology was performed an arthroscopic intracapsular suture using an outside-in transfer, all-inside repair technique, which is a modified method of the outside-in and all-inside technique using the needle of a 10-mL sterile syringe, for Palmer type 1B TFCC tears. A No. 2 polydioxanone suture was threaded through the needle and entered the wrist joint. Next, the needle was withdrawn carefully along the suture to the proximal tear ulnar surface of the TFCC and penetrated the TFCC, exiting the articular cavity surface of the ulnar side of the torn TFCC. Finally, arthroscopic knotting was performed. RESULTS This new treatment was as effective as the previously arthroscopic techniques and had the advantages of no additional incision and decreased risk of operation-related complications. The incidence of thread knots in the group A (28.57%) was significantly higher than that in the group B (0%), and the difference was statistically significant (P = 0.024). There was no significant difference in VAS score and modified Mayo wrist function scores between the two groups (P > 0.05). CONCLUSIONS The outside-in transfer, the all-inside repair technique is suitable for Palmer type 1B Atzei class 1 TFCC tears. We recommend this technique as a useful alternative to the conventional methods of repairing Palmer type 1B TFCC tears.

Abstract
BACKGROUND IOL fixation without capsular support presents challenges for surgeons. Although innovative techniques were developed to address subluxated IOLs, adjustable IOL fixation methods are seldom reported. We introduce a novel two-way adjustable double-knots intrascleral fixation combined with single sclerotomy looping technique for fixing intraocular lenses (IOL) or IOL-capsular bags. METHODS A bent 30-gauge needle threaded with 8 - 0 polypropylene was introduced into the eye. A gripping forceps assisted the haptic looping. Two overhand knots were made with 8 - 0 polypropylene thread. The knots were incarcerated into a scleral tunnel made by a 30-gauge needle, with two ends of the thread left at each side of the tunnel. The IOL was adjusted to the premium position with adequate tension by pulling either end of the threads. The study included 19 eyes with aphakia, subluxated IOL-capsular bags, or subluxated crystalline lenses. The mean followed up period was 18.9 ± 7.1 months with evaluations of uncorrected visual acuity (UCVA), intraocular pressure, slit-lamp examination, and swept-source optical coherence tomography of the anterior segment. RESULTS UCVA increased from 1.28 ± 0.74 at baseline to 0.44 ± 0.51 (logMAR) at final visit (P < 0.001). All IOLs were fixed well-centered. The mean IOL tilt was 3.5°±1.1°. Postoperative complications included transient IOP elevation (15.8%), hypotony (10.5%), and cystoid edema (5.3%) which resolved within 4 weeks. CONCLUSIONS We presented a novel adjustable technique for IOL fixation, which stabilize IOLs by using an intrascleral double-knots structure. This technique minimized surgical manipulations by using a single sclerotomy looping technique without large conjunctival dissection and scleral flap creation. The technique offers a reliable and optimal IOL positioning and improved visual outcomes in patients undergoing scleral fixed IOL implantation.

Abstract
Objective To investigate the early effectiveness of arthroscopic repair of supraspinatus tendon tears with douple-pulley suture-bridge. Methods The clinical data of 38 patients with supraspinatus tendon tears who met the selection criteria between September 2020 and July 2022 were retrospectively analyzed, and all of them were treated with arthroscopic double-pulley suture-bridge technique. There were 15 males and 23 females, aged from 43 to 77 years, with an average of 61.5 years. There were 15 cases of left shoulder and 23 cases of right shoulder. Seven cases had a history of trauma, and the other 31 cases had no obvious inducement. The main clinical symptoms of the patient were pain in lifting the shoulder joint and hug resistance test (+). The time from onset of symptoms to admission ranged from 6 to 19 months, with an average of 10.3 months. Flexion, abduction, and external rotation of the shoulder were recorded before operation and at 3 and 12 months after operation. Pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, and American Society of Shoulder and Elbow Surgeons (ASES) score before operation and at 12 months after operation. Tendon healing, tendon continuity, and tension were evaluated by MRI at 3-6 months after operation, and patient's satisfaction was evaluated at last follow-up. Results All the incisions healed by first intention, and there was no complication such as incision infection or nerve injury. All patients were followed up 12-34 months, with an average of 23.3 months. VAS score, UCLA shoulder score, and ASES score at 12 months after operation were significantly better than those before operation ( P<0.05). The external rotation range of shoulder joint significantly improved at 3 and 12 months after operation ( P<0.05), and it further improved at 12 months after operation when compared with 3 months after operation ( P<0.05). There was no significant difference in the range of flexion and abduction at 3 months after operation when compared with those before operation ( P>0.05), but the range of flexion and abduction at 12 months after operation significantly improved when compared with those before operation and at 3 months after operation ( P<0.05). MRI reexamination was performed in 28 patients at 3-6 months after operation. Among them, 25 patients had intact supraspinatus tendon structure, good tension, and tendon healing, and 3 patients had type 1 retear. The remaining 10 patients refused to undergo MRI reexamination because of the satisfactory effectiveness. At last follow-up, 29 patients (76.3%) were very satisfied with the results, 6 (15.7%) were satisfied, and 3 (7.8%) were not satisfied. Conclusion Arthroscopic double-pulley suture-bridge technique can achieve the effect of suture bridge operation, reduce the cost of operation and the risk of type 2 retear, and the early effectiveness is satisfactory, but the shoulder joint movement is limited within 3 months after operation.

Abstract
Objective To investigate the effectiveness of arthroscopic multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of anterior cruciate ligament (ACL) involving the anterior root of lateral meniscus (LM). Methods A retrospective analysis was conducted on the clinical data of 28 patients with tibial insertion avulsion fracture of ACL involving the anterior root of LM who were treated with arthroscopic multi-point fixation with anchor and suture between October 2017 and January 2023. There were 12 males and 16 females with the mean age of 26 years (range, 13-57 years). There were 20 cases of sports injury and 8 cases of traffic accident injury. In 2 cases of old fracture, the time from injury to operation was 45 days and 90 days, respectively; in 26 cases of fresh fracture, the time from injury to operation was 3-20 days (mean, 6.7 days). According to the Meyers-McKeever classification, there were 4 cases of type Ⅱ, 11 cases of type Ⅲ, and 13 cases of type Ⅳ. The preoperative Lysholm knee function score was 42.1±9.0, the International Knee Documentation Committee (IKDC) score was 40.0±7.3, and the Tegner score was 0.7±0.7. Results All operations were successfully completed, and the incisions healed by first intention. All the 28 patients were followed up 5-60 months (mean, 20.4 months). During the follow-up, there was nocomplication such as infection, vascular or nerve injury, loosening or breakage of internal fixator, or stiffness of knee joint. Postoperative X-ray films showed satisfactory fracture reduction and firm fixation. All fractures healed clinically, and the healing time was 8-16 weeks (mean, 10.3 weeks). At last follow-up, Lachman test and anterior drawer test were negative. At last follow-up, Lysholm knee function score was 92.4±5.5, IKDC score was 91.6±4.4, and Tegner score was 5.2±1.1, which significantly improved when compared with preoperative scores ( t=-22.899, P<0.001; t=-29.870, P<0.001; t=-19.979, P<0.001). Conclusion Multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of ACL involving the anterior root of LM can not only fix the LM, but also effectively reduce and fix the avulsion fracture, which can obtain good effectiveness.

BACKGROUND Training programmes for obstetrics and gynaecology (O&G) and general surgery (GS) vary significantly, but both require proficiency in laparoscopic skills. We sought to determine performance in each specialty. DESIGN Prospective, observational study. SETTING Health Education England North-West, UK. PARTICIPANTS 47 surgical trainees (24 O&G and 23 GS) were subdivided into four groups: 11 junior O&G, 13 senior O&G, 11 junior GS and 12 senior GS trainees. OBJECTIVES Trainees were tested on four simulated laparoscopic tasks: laparoscopic camera navigation (LCN), hand-eye coordination (HEC), bimanual coordination (BMC) and suturing with intracorporeal knot tying (suturing). RESULTS O&G trainees completed LCN (p<0.001), HEC (p<0.001) and BMC (p<0.001) significantly slower than GS trainees. Furthermore, O&G found fewer number of targets in LCN (p=0.001) and dropped a greater number of pins than the GS trainees in BMC (p=0.04). In all three tasks, there were significant differences between O&G and GS trainees but no difference between the junior and senior groups within each specialty. Performance in suturing also varied by specialty; senior O&G trainees scored significantly lower than senior GS trainees (O&G 11.4±4.4 vs GS 16.8±2.1, p=0.03). Whilst suturing scores improved with seniority among O&G trainees, there was no difference between the junior and senior GS trainees (senior O&G 11.4±4.4 vs junior O&G 3.6±2.1, p=0.004). DISCUSSION GS trainees performed better than O&G trainees in core laparoscopic skills, and the structure of O&G training may require modification. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Registry (NCT05116332).

Fixation strength in arthroscopic labral repair of the hip: A head-to-head comparison of the biomechanical performance of a biocompatible vs. all-suture anchor in the setting of acetabuloplasty. PLoS One 2023; 18:e0293738.

Abstract
Much is known about the biomechanical performance of various types of suture anchors commonly used for labral fixation in the shoulder; however, similar studies in the hip are less common. We sought to compare all-suture and polyether ether ketone small-diameter anchors in the setting of labral repair during hip arthroscopy, with and without acetabuloplasty. We hypothesized that the biomechanical properties of the all-suture group when compared to polyether ether ketone anchors would be similar amongst native acetabula and significantly less following acetabuloplasty and that pullout forces would be reduced in the anterior and inferior regions of the acetabulum compared to the superior region. Bone density was measured in nine matched pairs of fresh-frozen cadaveric acetabula in the superior, anterosuperior, and anterior regions. Acetabuloplasty was performed in all three regions, while the contralateral acetabulum was left in situ as a control. Suture anchors were placed such that one each of two different types was placed within each region. Specimens were tested in cyclic fatigue and loaded to failure. The all-suture group had significantly higher cyclic displacement compared to the polyether ether ketone, but there was no significant difference in ultimate load, regardless of acetabuloplasty. Amongst all non-resected specimens, the lowest bone density was observed consistently in the inferior region. Our results indicate that, with or without acetabuloplasty, a small-diameter polyether ether ketone anchor appears to be more stable than an all-suture anchor, which needs to be set first.

Abstract
SUMMARY Wound dehiscence, with an estimated occurrence rate greater than 4% in plastic surgery, is generally underreported, and can be an indicator of increased mortality and remission rates. The authors developed the lasso suture as a stronger alternative to the current standard patterns. The lasso suture takes less time to perform than the standard high-tension wound repair method. The authors dissected caprine skin specimens to create full-thickness wounds for suture repair using simple interrupted, vertical mattress, horizontal mattress, and deep dermal with running intradermal (DDR) sutures ( n = 10) and lasso sutures ( n = 9). They then conducted uniaxial failure testing to quantify the suture rupture stresses and strains. They also measured the suture operating time with medical students and residents (PGY or MS programs) performing wound repair (10-cm wide, 2-cm deep, 2-0 polydioxanone sutures) on soft-fixed human cadaver skin. The lasso stitch had a greater first-suture rupture stress compared with all other patterns ( P < 0.001): 2.46 ± 0.27 MPa for lasso versus 0.69 ± 0.14 MPa for simple interrupted, 0.68 ± 0.13 MPa for vertical mattress, 0.50 ± 0.10 MPa for horizontal mattress, and 1.17 ± 0.28 MPa for DDR sutures. Performing the lasso suture was 28% faster than performing standard DDR (264 ± 21 versus 349 ± 25 seconds; P = 0.027). In summary, the authors showed that the lasso has superior mechanical properties compared with the studied traditional sutures, and that the new technique can be performed more quickly than the current standard (DDR stitch) for high-tension wounds. Future animal and in-clinic studies will be helpful to confirm the authors' findings in this proof-of-concept study. CLINICAL RELEVANCE STATEMENT The authors propose the lasso suture, a new suturing method with improved tensile performance compared with traditional techniques and a faster operative time than the deep dermal stitch typically used for high-tension wounds in reconstructive surgery to prevent wound dehiscence.

Abstract
ABSTRACT Performing endothelial keratoplasty in an eye with a damaged or irregular iris can result in uneven air filling, air escape behind the pupil, anterior iris curvature, a shallow anterior chamber, an uneven anterior chamber depth, difficulty inserting and opening the graft, and iris trauma. We herein present a modified basket suture technique to prevent these iris complications. Before insertion of the corneal donor graft, a double-armed 9-0 polypropylene suture on a curved needle is inserted from 4 equidistant points at the corneal limbus to create a box configuration directly anterior to the iris. These sutures prevent the iris from moving toward the cornea and the anterior chamber from becoming shallow when air replacement is performed. The suture also reduces intraoperative or postoperative iris-related problems because the air filling is more uniform and less prone to migration.

Abstract
INTRODUCTION Achilles tendon sleeve avulsion (ATSA) is a rare injury that often results from pre-existing insertional Achilles tendinopathy and occurs when a tendon avulses from the insertion as a continuous sleeve. To date, outcomes of operative treatment for ATSA in older patients have not been reported. Therefore, this study aims to compare the characteristics and outcomes of Achilles tendon (AT) reattachment with or without tendon lengthening for ATSA between older and younger patients. MATERIALS AND METHODS This study enrolled 25 consecutive patients who underwent operative treatment following a diagnosis of ATSA between January 2006 and June 2020. The inclusion criterion was a minimum follow-up duration of one year. The enrolled patients were divided into two groups according to their age at operation: ≥ 65 years (group 1, 13 patients) and < 65 years (group 2, 12 patients). AT reattachment was performed in all patients using two 5.0-mm suture anchors after an inflamed distal stump resection in the 30° plantar-flexed ankle position. RESULTS The degree of active dorsiflexion and plantar flexion, mean visual analog scale score, and Victorian Institute of Sports Assessment-Achilles scores at the final follow-up were not significantly different between the two groups (P > 0.05 each). The rate of satisfactory clinical outcomes (defined as fair or greater) was 84.6% and 91.7% in groups 1 and 2, respectively. CONCLUSION We observed that comparable clinical outcomes could be achieved after AT reattachment with or without lengthening for ATSA between older and younger patients.

Abstract
PURPOSE This study aimed to describe a novel technique to facilitate intrascleral fixation of the intraocular lens (IOL). METHODS Two 27-gauge trocars were placed at an angle of 180° and a distance of 2 mm from the corneal limbus. A silicone microtube with an external diameter of 0.2 mm was introduced through a sclerocorneal incision and withdrawn via a trocar using retinal forceps. The tips of the IOL haptics were connected to the microtube. After the implantation of the IOL into the chamber, the haptics were externalized through the scleral site by pulling the microtubes. Each tip of the haptics was flanged and buried into the scleral tunnel. RESULTS The IOL was successfully placed with this method without any complications. CONCLUSION This study presented a novel technique for intrascleral IOL fixation using a silicone microtube. We believe that our technique might increase surgical safety and help decrease the operative time for both anterior and posterior segment techniques.

Abstract
PURPOSE To describe a buried variation of the temporary suture tarsorrhaphy and determine its efficacy period. METHODS This retrospective case review includes 11 patients needing corneal protection. Six patients had lagophthalmos from facial nerve palsy, 4 had cicatricial ectropion, and 1 had neurotrophic keratopathy. A total of 14 buried temporary suture tarsorrhaphies (BTSTs) were placed. The duration of the BTST was the main outcome. The corneal status before and throughout the BTST was monitored. The eyelids were examined for any undesired changes from the BTST. RESULTS The mean duration of the BTST was 97.5 days, with a maximum of 273 days. Aside from one spontaneous dehiscence 5 days after placement, all BTSTs held until intentional removal. Five BTSTs were removed for a more definitive surgical procedure, 6 were removed after resolution of the initial indication, and 2 are still in place as the patient awaits surgery. All cases of keratopathy improved after BTST placement. There were no complications and no undesired eyelid changes. CONCLUSIONS The BTST is a simple, fast, safe, and effective procedure that can be performed in the clinic or inpatient to immediately improve ocular surface coverage. As a minimally invasive procedure that can easily last several months, the BTST is an excellent option for patients who require more intense intervention than medical management alone. It can also securely bridge patients to a permanent solution such as lateral canthal resuspension.

Abstract
Background Knot configuration is an important but relatively neglected topic in microvascular anastomosis literature. Objective To study the differences between end-to-end microvascular anastomosis performed with two-throw reef knots as compared to traditional three-throw knots in a rat femoral artery model at the histological level. Material and Methods Sprague Dawley rats underwent end-to-end microvascular anastomosis of the right femoral artery (one-way-up method). The rats were divided into two groups: two-throw reef knots versus traditional three-throw knots. The patency was checked by the standard empty refill method. After 2 weeks, the rats underwent re-exploration. An anastomotic segment was sent for histological analysis. Histological alterations including luminal patency and changes in Tunica intima, Tunica media, and Tunica adventitia were compared between the two groups. Results Twenty-nine rats were operated on by the senior author (17 by three-throw and 12 by two-throw reef knots). In the two-throw reef knot group versus the traditional three-throw knot group, the immediate patency rates were 100% versus 82.4%, and the delayed patency rates were 90.9% versus 62.5%, respectively. The histopathological patency rates were concordant with delayed patency rates. Subintimal proliferation and fibrosis were comparable in both groups. Adventitial granulomas were noted in all, irrespective of the knotting technique. Tunica media preservation rates for the two-throw reef knot versus the traditional three-throw knot group were 63.6% versus 0%. Five rats were operated by the beginner in the field, all by two-throw reef knots (to assess the safety of this new method in the hands of a beginner). Conclusion Microvascular anastomosis performed with two-throw reef knots appears not only feasible but better in terms of anastomosis patency. Histological superiority in terms of Tunica media preservation further validates the technique.

Abstract
BACKGROUND Surgical site infections (SSIs) are one of the most common complications following diverting loop ileostomy (DLI) closures. This study assesses SSIs after DLI closure and the temporal trends in skin closure technique. METHODS A retrospective review was conducted using the American College of Surgeons National Surgical Quality Improvement Program database for adult patients who underwent a DLI closure between 2012 and 2021 across a multistate health system. Skin closure technique was categorized as primary, primary + drain, or purse-string closure. The primary outcome was SSI at the former DLI site. RESULTS A SSI was diagnosed in 5.7% of patients; 6.9% for primary closure, 5.7% for primary closure + drain, and 2.7% for purse-string closure (p = 0.25). A diagnosis of Crohn's disease, diverticular disease, and increasing operative time were significant risk factors for SSIs. There was a positive trend in the use of purse-string closure over time (p < 0.0001). CONCLUSIONS This study identified a low SSI rate after DLI closure which did not vary significantly based on skin closure technique. Utilization of purse-string closure increased over time.

Abstract
In arthroscopic rotator cuff repair, poor tendon quality, medially based tears, lateral tendon loss, or limited tendon mobility can all preclude the use of double-row suture constructs, presenting a challenge in achieving secure fixation and tendon-to-bone healing. Rip-stop suture configurations can be used in these settings to improve resistance to tissue cutout and provide enhanced biomechanical characteristics compared with standard single-row repairs. The load-sharing rip-stop technique uses 2 double-loaded medial suture anchors, which are placed adjacent to the articular margin, and 1 rip-stop suture tape, which is independently secured to bone with 2 lateral knotless anchors. The load-sharing rip-stop technique has been shown to improve ultimate load to failure by 1.7 times compared with a single-row repair. Clinically, this technique has been associated with a 53% healing rate of large and massive rotator cuff tears, compared with only 11% healing when using single-row repair. A completely knotless variation rip-stop configuration also has been described and shown to be biomechanically equivalent to a single-row repair with triple-loaded anchors. For surgeons desiring a single-row repair only, the knotless rip-stop therefore presents an advantage by eliminating the need for knot-tying and decreasing operative time.

Abstract
BACKGROUND Complete closure of mucosal defects after colorectal endoscopic submucosal dissection (ESD)/piecemeal endoscopic mucosal resection (p-EMR) procedures reduces postoperative adverse events, but the complete closure rate of the traditional method using only hemostatic clips is not satisfactory. Therefore, we invented a continuous suture technique using a barbed suture and clips to increase the complete closure rate of colorectal mucosal defects. METHODS Patients with a single large (≥ 2 cm) colorectal lesion were recruited. After completion of the ESD/p-EMR procedures, they were randomly allocated to the treatment group or control group. The mucosal defects of the treatment group were closed using barbed suture and clips, while the control group was closed using only clips. RESULTS From January 18, 2022 to April 13, 2022, a total of 62 patients with colorectal lesions were enrolled, with 31 patients in each group. Complete closure was achieved in 29 patients (93.5%) in the treatment group and 18 patients (58.1%) in the control group (P = 0.001). The median closure time was 13 min in the treatment group and 19 min in the control group (P < 0.001). The median closure speed was 6.4 cm2/10 min in the treatment group and 3.5 cm2/10 min in the control group (P = 0.008). CONCLUSIONS This study provided a clinically feasible continuous suture technique that was safe and effective for the complete closure of colorectal mucosal defects after endoscopic resection.

Abstract
PURPOSE Barbed suture provides a rapid and effective method for closure in minimally invasive surgery. However, postoperative complications involving barbed suture have been reported in recent years. The aim of this study is to introduce a novel hidden stitching technique for peritoneal closure in laparoscopic hernia repair. METHOD This study retrospectively analyzed the data of patients with laparoscopic transabdominal preperitoneal patch (TAPP). In the hidden stitch (HS) group, the barbed suture was hidden on the dorsal side of the peritoneum and two stitches were returned in the opposite direction after the suture reached the end point. In the non-hidden stitch (NHS) group, the barbed sutured was exposed in the peritoneal cavity with a tail stump of approximately 10 mm preserved to prevent the peritoneal sutures from loosening. RESULTS Twenty-seven patients in the HS group were compared with 53 in the NHS group. There were no differences in age, body mass index, surgical bleeding, or length of hospital stay between the two groups. The peritoneal defect closure time was slightly longer (3 min) in the HS group, but the overall operation time was not significantly extended. There were 8 cases of postoperative complications (P = .035) including 4 cases of bowel obstruction due to the tail of the barbed thread penetrating the small intestine mesenteric and two cases of seroma. There were no postoperative complications in the HS group. CONCLUSIONS The hidden stitch method is a safe and feasible peritoneal closure technique that may reduce postoperative complications caused by barbed suture in laparoscopic hernia repair.

Abstract
PURPOSE To describe and evaluate the effectiveness of the modified Carlevale intraocular lens (IOL) fixation technique, using two vitrectomy ports as lens plug fixation sites. MATERIALS AND METHODS This prospective, consecutive, interventional study examined 60 eyes in 60 patients, who underwent 25- or 23-gauge vitrectomy for an IOL subluxation/luxation, lens dislocation, or aphakia, with Carlevale IOL implantation. RESULTS Postoperatively, transient ocular hypotension was observed in four eyes. The mean refractive prediction error was -0.27 ± 0.78 diopters. No postoperative complications, such as retinal detachment, endophthalmitis, or IOL dislocation, were observed in the 4-month follow-up. CONCLUSION This new technique may be simple, fast, and effective because of fewer scleral wounds and fewer postoperative complications.

Abstract
Controversy remains regarding the optimal technique and suture type for wound closure after carpal tunnel surgery. Adult patients undergoing open carpal tunnel release were prospectively randomized to receive either interrupted, buried Monocryl sutures or traditional nylon horizontal mattress sutures for their wound closures. At the 2-week and 6-week postoperative visits, Patient and Observer Scar Assessment Scale questionnaires were completed. At 2 weeks, patients and observers had a significantly better opinion of incisions closed with Monocryl. By 6 weeks, neither patients nor observers found a difference between suture types in any category. Scars of wounds closed with Monocryl did not change appreciably in appearance between 2 and 6 weeks. However, patients and observers noted significant improvement in scar appearance in the nylon group over time. Monocryl suture represents an effective method for carpal tunnel closure that leads to improved patient- and observer-reported outcome scores in the early postoperative period compared with nylon.Level of evidence: II.

Abstract
BACKGROUND In specific clinical scenarios characterized by poor tissue conditions surrounding a wound, achieving stable flap fixation with standard sutures can be challenging. The anchoring flap suture technique, which is commonly used for soft tissue-to-bone attachment in cases of injury, may be an alternative and effective approach. CASE REPORT This report describes the successful application of the anchoring flap suture technique to repair a wound with exposed bone in a 39-year-old female patient. She presented with a 7% TBSA wound of the left trunk following hip disarticulation. After 4 operations, a wound with exposed iliac bone remained. Given the compromised condition of the tissues surrounding the exposed bone, the authors opted to anchor a local flap directly to the exposed bone. Steady flap fixation was achieved using the anchoring flap suture method, resulting in complete healing of that wound. Remarkably, no short- or long-term complications associated with the flap were observed. Three months after hospital discharge, the patient regained mobility, walking on 1 leg with the assistance of a 4-legged walker. CONCLUSION The anchoring flap suture technique seems to be a reliable and effective treatment option, particularly in cases in which inadequate soft tissue precludes the use of traditional flap fixation using standard sutures.

Abstract
We assessed the influence of different directions of suture strands using the double Tsuge repair on the resistance to gap formation and mode of failure. In total, 25 porcine flexor digitorum profundus tendons were split into two groups. One group was repaired using a conventional double Tsuge suture created by two bands of looped suture placed longitudinally parallel (parallel method), and the other group was repaired using a new technique comprising two bands of looped suture placed in a crossed fashion in the anterior and posterior half of the tendon (cruciate method). The repaired tendons were subjected to linear, non-cyclic load-to-failure tensile testing. The cruciate method had a significantly higher mean load at a 2-mm gap tensile load (29.7 N [SD, 8.3]) than the parallel method (21.6 N [SD, 4.9]) and failed significantly more often due to suture pull-out. The direction of a core suture and its location within the tendon affect both gap resistance and the mode of failure of repair when using the double Tsuge suture technique, with a cruciate configuration achieving a greater gap resistance than a parallel one.

Novices can assess microsurgery performance, and this is enhanced using the Manual Suture Parameters for Training and Assessment (M-SParTA) scoring system. J Plast Reconstr Aesthet Surg 2023; 86:211-213. [PMID: 37769482 DOI: 10.1016/j.bjps.2023.09.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/15/2023] [Accepted: 09/07/2023] [Indexed: 10/03/2023]
Abstract
This study explores how novices could effectively evaluate the quality of microsurgical suturing. That would be enhanced with using a novel Manual Suture Parameters for Training and Assessment (M-SParTA), which supported novices with guidance on the objective parameters, in order to increased the accuracy of scoring ability. We also propose the following initial framework to train novices in microsuturing using a standardised task: 1) Exposure; 2) Assessment; 3) Hands-on and self-assessment. The independent learning cycle with targeted supervision provides novices with greater autonomy and a less stressful environment that could enhance skills training.

Abstract
OBJECTIVES To quantify the buccal bone thickness, area, and perimeter following guided bone regeneration (GBR) using stabilizing periosteal sutures. The loss in hard tissue volume may impair proper implant placement. GBR has been used to regenerate the lost alveolar ridge prior to or at the same time as dental implant placement. The most important factor for GBR success is graft stability. The periosteal mattress suture (PMS) stabilizing technique is an alternative to pins and screws to stabilize bone grafting material and has the advantage of not requiring the removal of the fixing devices. MATERIALS AND METHODS A CBCT was acquired before and 6 months after surgery from six patients who underwent GBR with the PMS stabilizing technique. Images were analyzed for buccal bone thickness, area, and perimeter. RESULTS The mean change in buccal bone thickness was 3.42 mm (± 1.31 SD) and proved statistically significant (P = .005). The mean change in bone crest area also proved statistically significant (P = .001). No significant difference was found in bone perimeter (P = .12). CONCLUSIONS The PMS technique delivered optimal results without clinical complications. This study shows the potential of this technique as an alternative to pins or screws for graft stabilization in the esthetic zone.

Scleral fixation of iris-Intraocular lens complex (Reper®) with Canabrava double-flanged technique: a case report. Arq Bras Oftalmol 2023; 86:e20230060. [PMID: 35544930 DOI: 10.5935/0004-2749.20230060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 08/31/2021] [Indexed: 10/27/2023] Open
Abstract
A 38-year-old patient who developed aphakia and aniridia secondary to trauma suffered from vision loss. To improve her vision, an iris-intraocular lens complex (Reper®) was fixed to the sclera with Canabrava's double-flanged technique. There was a satisfactory increase in the patient's visual acuity and no complications were observed during the 6-months follow-up. Canabrava technique simplifies and improves the fixation of the iris-intraocular lens complex to the sclera. It is a safe option that does not require scleral flaps or knots.
