A novel reopenable clip with sharp claw for complete closure of mucosal defects after colorectal endoscopic submucosal dissection.

The MANTIS Closure Device (MCD; Boston Scientific, Marlborough, Massachusetts, USA) is a reopenable clip with a sharp claw used for closure after endoscopic submucosal dissection (ESD). We evaluated the effectiveness of the MCD for fast and complete closure after colorectal ESD. Cases involving closure with the MCD after ESD of 20-60-mm colorectal lesions between April 2023 and January 2024 were reviewed. The primary end point was complete closure of the ESD defect with the MCD. Secondary end points included closure time, delayed bleeding, delayed perforation, and post-ESD coagulation syndrome (PECS). MCD application involved: 1) grasping the mucosa on the anal-side of the defect; 2) pushing the clip toward the oral-side mucosa and deploying it; 3) adding other reopenable clips for complete closure. 61 cases involving MCD were analyzed. Mean tumor size was 32.3 (SD 9.2) mm. Complete closure rate was 98.4% and mean closure time was 6.9 (SD 2.6) minutes. The mean number of MCDs and other clips used was 1.0 (SD 0.1) and 4.7 (SD 1.4), respectively. Rates of delayed bleeding, delayed perforation, and PECS were 0%, 0%, and 9.8%, respectively. Fast and complete closure after colorectal ESD was successfully achieved using the MCD.

Orthopedic Skin Closure in South India: Sutures Versus Staples and Their Postoperative Outcomes.

Introduction Skin closure is an essential step in deciding the success of a surgery. Despite this, the choice of skin closure material is frequently overlooked when making surgical decisions. Skin closure plays an important role in promoting rapid wound healing and decreasing the length of hospital stay, especially in orthopedic surgeries. Our study focused on comparing the outcome of wound closure in orthopedic surgeries with sutures and staples in a South Indian population. Materials and methods We enrolled 120 patients undergoing orthopedic procedures at Chettinad Hospital and Research Institute from July 2023 to February 2024. Patients were randomly assigned to skin closure with either staples or sutures. Wound inspection was done on the 2nd, 5th, 7th and 12th post-operative days. The patients were evaluated at six months using the Visual Analog Scale (VAS) and Hollander Wound Evaluation Score (HWES). Results Staple closure significantly reduced mean closure time (5.2 ± 0.9 minutes) compared to sutures (12.6 ± 1.5 minutes, p < 0.0001). Pain during staple removal was less (VAS score 1.41 ± 0.15) than with suture removal (VAS score 1.57 ± 0.2, p = 0.024). Although patient satisfaction was similar between the groups (Staples: 8.35 ± 0.45 vs. Sutures: 8.0 ± 0.5, p = 0.062), staples provided superior cosmetic outcomes (HWES: 4.1 ± 0.7) compared to sutures (HWES: 3.3 ± 0.6, p = 0.003). Complication rates, including infection, discharge, and hypertrophic scar formation, were comparable between the two methods. Conclusion Staple closure in orthopedic surgeries offers several advantages over sutures, including reduced operative time, less pain during removal, and superior cosmetic results. These benefits occur without an increased risk of wound complications. This study suggests that staples may be a preferable option for skin closure in orthopedic procedures, though further research with extended follow-up is needed to fully assess long-term outcomes.

Enhanced platelet function through CAR-T cell therapy in relapsed/refractory multiple myeloma

The influence of chimeric antigen receptor T (CAR-T) cell therapy on platelet function in relapsed/refractory (R/R) multiple myeloma (MM) has not been thoroughly investigated. Our cohort comprised fifty MM patients treated with CAR-T cells. The mean platelet closure time (PCT) induced by collagen/adenosine diphosphate (CADP) in peripheral blood was significantly prolonged before lymphodepletion (195.24 ± 11.740 s) and notably reduced post-CAR-T cell therapy (128.02 ± 5.60 s), with a statistically significant improvement (67.22, 95% CI 46.91–87.53, P < 0.001). This post-treatment PCT was not significantly different from that of healthy controls (10.64, 95% CI 1.11–22.40, P > 0.05). Furthermore, a pronounced enhancement in PCT was observed in patients with a response greater than partial remission (PR) following CAR-T cell infusion compared to pre-treatment values (P < 0.001). An extended PCT was also associated with a less favorable remission status. In patients with cytokine release syndrome (CRS) grades 0–2, those with a PCT over 240.5 s exhibited a shorter progression-free survival (PFS), with median PFS times of 10.2 months for the PCT > 240.5 s group versus 22.0 months for the PCT ≤ 240.5 s group. Multivariate analysis revealed that a PCT value exceeding 240.5 s is an independent prognostic factor for overall survival (OS) in R/R MM patients after CAR-T cell therapy. The study demonstrates that CAR-T cell therapy enhances platelet function in R/R MM patients, and PCT emerges as a potential prognostic biomarker for the efficacy of CAR-T cell therapy.

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.

Comparative Evaluation of the Aesthetic Outcomes of Octyl-2-Cyanoacrylate Skin Adhesive and Ethilon Suture in Maxillofacial Surgery - A Randomised Clinical Study.

Wound closure methods have evolved, attributed to the armamentarium including the synthetic sutures, staples, surgical adhesive tapes and, most recently, the cyanoacrylate tissue adhesives. Cyanoacrylates have shown promising results in terms of aesthetic outcomes in other fields of surgery. The aim of this study is to compare the aesthetic value of Dermabond over Ethilon suture when used in case of facial surgical incisions. The purpose of this study was to demonstrate the efficacy of Dermabond for wound closure in the head-and-neck region. This study involved 20 subjects undergoing maxillofacial surgery. In 10 subjects, skin closure was done with conventional suturing (Ethilon) and other 10 subjects with tissue glue (2-octyl cyanoacrylate). Observations regarding skin closure time and scar assessment were made, and their results were compared. The mean time for closure in the Dermabond group was 217.2 ± 42.0 s and for Ethilon suture group was 383.3 ± 140.2 s. Dermabond was significantly better than Ethilon sutures at both 1 month and 3 months with P = 0.001 and P < 0.001, respectively. For Dermabond, the average score improved from 8.2 ± 2.5 at 1 month to 6.1 ± 1.6 at the 3rd month. The improvement was statistically significant (P = 0.001) for Ethilon sutures; the average score improved from 12.0 ± 1.2 at 1 month to 10.2 ± 2.0 at 3rd month. The improvement was statistically significant (P = 0.038). Adhesive glue appears to be superior to conventional suturing in clean elective surgeries. It is a safe and effective method of skin closure with less operative time and better cosmesis of the scar.

Deroofing: A safe, effective and well-tolerated procedure in patients with hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a recurrent, debilitating, chronic disorder of the pilosebaceous unit. Although advances in HS treatment have been made, more than 45% of patients remain dissatisfied with systemic treatment, and more than one-third are dissatisfied with surgical procedures. A prospective, observational study on the deroofing procedures in HS with special attention paid to patient satisfaction and complications. HS lesions were assessed clinically and by the use of ultrasound. Patients reported outcomes, including pain, itch and satisfaction, were measured at 24 h post-surgery by a numeric rating scale (NRS) ranging from 0 to 10. Additionally, the timeline of objective wound closure reported by patients in (weeks), in addition to the need for any analgesics use, were both evaluated. The mean closure time of the post-deroofing wound was assessed as 4.4 ± 1.9 weeks. A statistically longer time was necessary for complete closure in males than in females (4.9 ± 2.2 weeks and 3.9 ± 1.6 weeks, respectively; p = 0.046). The closure time correlated positively yet weakly with the HS tunnel's width (r = 0.27, p = 0.016) and length (r = 0.228, p = 0.044). Patients assessed mean pain at 24 h post-op as mild with 0.7 ± 1.2 points according to NRS, with no differences between sexes. Similarly, itch in the first 24 h was assessed as mild with 1.8 ± 1.1 points, without differences between sexes. No pain, itch or adverse events were reported after 1 week following deroofing. Moreover, no cases of wound infection were reported. An overall patient satisfaction was assessed as 9.9 ± 0.4 points (range 9-10 points). Deroofing is an easy, effective and safe dermatosurgical procedure that does not require surgical experience or operating theatre. It is associated with no complications and very low post-op pain and should be part of holistic HS management.

Comparison of efficacy of paracetamol and ibuprofen for treatment of hemodynamically significant patent ductus arteriosus in preterm infants

Background: Indomethacin and ibuprofen (IBU) have been approved for the pharmacological closure of hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants. Recent works have demonstrated that paracetamol (PCM) can also be used but more research is required regarding efficacy and safety. Objectives: The objective is to compare the efficacy and safety of PCM and IBU for the treatment of hsPDA in preterm infants. Methodology: An observational study was designed with ethical clearance and parental consent. Patients were evaluated for hsPDA by clinical and 2 D echo findings. After inclusion and exclusion criteria, consecutive 100 patients were assigned between PCM and IBU and were given a 3-day course. After echocardiographic and clinical evaluation, if required, a second course with same drug was given. The outcome measures were the rate of ductal closure, the safety of drugs, and adverse events. Results: The PCM group had a closure rate of 76.25% and the IBU group had 75%. IBU had a significantly higher rate of closure in the first course (45% vs. 16.25%). The mean closure time observed was 4.54 days and 4 days for PCM and IBU, respectively. PCM gave a higher closure rate in the low-birth-weight group and where platelet counts were below normal. Regarding the safety aspect also no significant difference between groups was observed. Conclusion: PCM can be advised as a first-line treatment for hsPDA cases in preterm infants and is a better choice in cases of comorbidities and patients with low platelet count.

PFA-100 System: A New Method for Assessment of Platelet Dysfunction.

This is a celebratory reprint of a historical paper published in STH in 1998. The original Abstract follows.The PFA-100 system is a platelet function analyzer designed to measure platelet-related primary hemostasis. The instrument uses two disposable cartridges: a collagen/epinephrine (CEPI) and a collagen/ADP (CADP) cartridge. Previous experience has shown that CEPI cartridges detect qualitative platelet defects, including acetylsalicylic acid (ASA)-induced abnormalities, while CADP cartridges detect only thrombocytopathies and not ASA use. In this seven-center trial, 206 healthy subjects and 176 persons with various platelet-related defects, including 127 ASA users, were studied. The platelet function status was determined by a platelet function test panel. Comparisons were made as to how well the defects were identified by the PFA-100 system and by platelet aggregometry. The reference intervals for both cartridges, testing the 206 healthy subjects, were similar to values described in smaller studies in the literature (mean closure time [CT] of 132 seconds for CEPI and 93 seconds for CADP). The use of different lot numbers of cartridges or duplicate versus singleton testing revealed no differences. Compared with the platelet function status, the PFA-100 system had a clinical sensitivity of 94.9% and a specificity of 88.8%. For aggregometry, a sensitivity of 94.3% and a specificity of 88.3% were obtained. These values are based on all 382 specimens. A separate analysis of sensitivity by type of platelet defect, ASA use versus congenital thrombocytopathies, revealed for the PFA-100 system a 94.5% sensitivity in identifying ASA users and a 95.9% sensitivity in identifying the other defects. For aggregometry, the values were 100% for ASA users and 79.6% for congenital defects. Analysis of concordance between the PFA-100 system and aggregometry revealed no difference in clinical sensitivity and specificity between the systems (p > 0.9999). The overall agreement was 87.5%, with a Kappa index of 0.751. The two tests are thus equivalent in their ability to identify normal and abnormal platelet defects. Testing 126 subjects who took 325 mg ASA revealed that the PFA-100 system (CEPI) was able to detect 71.7% of ASA-induced defects with a positive predictive value of 97.8%. The overall clinical accuracy of the system, calculated from the area under the receiver operating characteristic curve, was 0.977. The data suggest that the PFA-100 system is highly accurate in discriminating normal from abnormal platelet function. The ease of operation of the instrument makes it a useful tool to use in screening patients for platelet-related hemostasis defects.

A novel twin-grasper assisted mucosal inverted closure technique for closing large artificial gastric mucosal defects

BackgroundLarge artificial gastric mucosal defects are always left unclosed for natural healing due to technique difficulties in closure. This study aims to evaluate the feasibility and safety of a new Twin-grasper Assisted Mucosal Inverted Closure (TAMIC) technique in closing large artificial gastric mucosal defects.MethodsEndoscopic submucosal dissection (ESD) was performed in fifteen pigs to create large gastric mucosal defects. The mucosal defects were then either left unclosed or closed with metallic clips using TAMIC technique. Successful closure rate and the wound outcomes were assessed.ResultsTwo mucosal defects with size of about 4.0 cm were left unclosed and healed two months after surgery. Thirteen large gastric mucosal defects were created by ESD with a medium size of 5.9 cm and were successfully closed with the TAMIC technique (100%), even in a mucosal defect with a width up to 8.5 cm. The mean closure time was 59.0 min. Wounds in eight stomachs remained completely closed 1 week after surgery (61.5%), while closure in the other five stomachs had partial wound dehiscence (38.5%). Four weeks later, all the closed defects healed well and 61.5% of the wounds still remained completely closed during healing. There was no delayed perforation or bleeding after surgery. In addition, there was less granulation in the submucosal layer of the closed wound sites than those under natural healing.ConclusionsThe present study suggests that TAMIC is feasible and safe in closing large artificial gastric mucosal defects and could improve mucosal recovery compared to natural healing process.

Comparison of healing of acute total tympanic membrane perforation between rats with and without excision of the mallear handle.

We compared the histological changes and hearing restoration during the healing of acute total tympanic membrane (TM) perforations between Sprague-Dawley (SD) rats with and without excision of the mallear handle. Bilateral, acute, and total TM perforations were created in 36 male SD rats. The mallear handle was preserved in the left ear (handle-preserved ear [HPE]) and excised from the right ear (handle-excised ear [HEE]). Endoscopical examination, auditory brainstem response (ABR) thresholds, histopathological, and scanning electron microscope (SEM) analysis were performed. Endoscopic photographs showed that all perforations in the 18 SD rats were closed. The mean closure times were 6.83 ± 0.85 and 8.50 ± 0.71 days in the HPE and HEE groups, respectively (p < .001). SEM images showed radial arrangement of fiber bundles in a single direction in HPEs, although normal arrangement was not achieved. In contrast, HEEs showed disorganized arrangement. At 1 month after perforation closure, the ABR thresholds at high frequencies were significantly higher in the HEE group than in the HPE group (p = .029 and p = .017 for 16 and 32 kHz, respectively). Additionally, the changes in ABR threshold were significantly different at high frequencies (p = .011 and p = .017 for 16 and 32 kHz, respectively) before and 1 month after perforation closure between the HPE and HEE groups, although the differences were not statistically significant at the remaining frequencies. Although the malleus handle may not affect the closure of total perforation in SD rats, it contributes to accelerate the perforation closure by possible guide the migration of proliferative epithelial cell on the upper halves of the annulus. Additionally, resection of the malleus handle impairs high frequency hearing recovery following spontaneous closure of the TM.

Effective and Secure Closure after Duodenal Endoscopic Submucosal Dissection: Combination of Endoscopic Ligation with O-Ring Closure and Over-the-Scope Clip

Duodenal endoscopic submucosal dissection (ESD) is associated with high incidences of intraoperative complications and delayed adverse events (AEs). Delayed AEs can be reduced by closing the post-ESD defects. We developed a new method of closure after duodenal ESD, combining endoscopic ligation with O-ring closure (E-LOC) with an over-the-scope clip (OTSC) (Band OTSC; B-OTSC). Here, we conducted a single-center, retrospective, observational study to investigate the efficacy and safety of the B-OTSC method for preventing delayed AEs in patients undergoing duodenal ESD. The study included nine patients with superficial nonpapillary duodenal epithelial tumors who underwent ESD and were closed with B-OTSC from February 2021 to February 2023. There were no delayed AEs (0%), the mean (± standard deviation) closure time was 53 ± 21.6 min, the complete closure rate was 100%, and the mean hospital stay was 7.8 ± 1.8 days. The sustained closure rates at postoperative days 3 and 7 were 88.9% and 88.9%, respectively. The historical analysis indicated a significant difference in cost between B-OTSC and conventional OTSC (p &lt; 0.01). In conclusion, B-OTSC was a safe, secure, and cost-effective method of closure after duodenal ESD, even in patients with post-ESD defects of more than half the circumference.

Comparative study of fibroblast growth factor 2 and ofloxacin ear drops for repairing large traumatic perforations: A randomized controlled study

ObjectiveThe objective of this study was to compare the healing outcome of fibroblast growth factor 2 (FGF2), ofloxacin ear drops (OFLX) and spontaneous healing for repairing large traumatic tympanic membrane (TM) perforations. Material and methodsA total of 75 traumatic large perforations with >1/4 of TM were randomly divided into FGF2 (n = 25), OFLX (n = 25), and spontaneous healing (n = 25) groups. The closure rates, closure times, and hearing gains were compared at 3 months. ResultsAt 2 weeks after treatment, the closure rate was 95.8 % in the FGF2 group, 96.0 % in the ofloxacin ear drops group, and 14.3 % in the spontaneous healing group (P < 0.01), respectively. At 3 months after treatment, the closure rate was 100 % in the FGF2 group, 100 % in the OFLX group, and 85.7 % in the spontaneous healing group, no among-group differences were significant (P > 0.05). The mean closure time was 9.69 ± 2.46 days in the FGF2 group, 9.45 ± 2.32 days in the OFLX group, and 30.94 ± 8.95 days in the spontaneous healing group (P < 0.01). The mean ABG was 10.37 ± 2.51 dB for the FGF2 group, 11.01 ± 1.31 dB for the OFLX group, and 10.86 ± 1.94 dB for the spontaneous healing group, no significant difference was found among three groups (P > 0.05). ConclusionsThis study suggested that both FGF2 and OFLX significantly shortened the mean closure time and improved the closure rate compared with spontaneous healing for repairing large traumatic perforations, while the healing outcome wasn't significantly different among FGF2 and OFLX groups.

THE OUTCOMES OF EARLY VERSUS LATE ILEOSTOMY CLOSURE

The best time to reverse an ileostomy is still largely unclear, however, there is growing evidence that delaying ileostomy closure may raise the risk of complications after the operation. The study's goal was to compare the outcomes of early ileostomy closure with late ileostomy closure after surgery. A prospective study was done to evaluate the results of patients who went through early ileostomy closure ( within 6 weeks) to those who had late ileostomy closure (&gt;6 weeks). All patients above 18 years old who had stoma subsequent surgery of bowel both in emergency and elective settings. In this prospective observational study, 60 patients were randomly assigned into two groups by the SNOSE method for closure of ileostomy at different intervals of time: early ileostomy closure (&lt;6 weeks), n=30, and late ileostomy closure (&gt;6 weeks), n=30. During three months, all patients were monitored for surgical complications. Early closure was performed on 30 of the 60 trial participants, with the mean time for closure in the early group being 4 weeks and 7.2 weeks in the late group. The postoperative problems and hospital stay did not vary considerably. In conclusion, based on our experience in both ileostomy closure groups at varied time intervals, the early group within 6 weeks did not increase post-operative problems and morbidity. The systematic assignment of patients with temporary loop stomas to early closure may improve patient well-being. Individualization of the usual approach of reserving patients for long-term stoma care is required, and further study is needed to compare disease-specific closure success.

Comparison of dermatotraction and negative pressure wound therapy for closure of cruris fasciotomy after 2023 Kahramanmaras earthquake.

This study aims to evaluate the results of patients who underwent cruris fasciotomy for acute compartment syndrome (ACS) after the 2023 Kahramanmaras earthquake and used subcuticular polydioxanone (PDS) method or negative pressure wound therapy (NPWT) with vacuum-assisted closure (VAC) for fasciotomy follow-up and closure of the defect. Between March 2023 and April 2023, a total of 52 patients (31 males, 21 females; mean age: 29±14.8 years; range, 5 to 74 years) were retrospectively analyzed. The patients were divided into two groups as the dermatotraction (PDS) group (Group 1, n=30), and the VAC group (Group 2, n=22). Data including demographic, clinical, and operative data such as fasciotomy closure time, graft need, and infection rate were recorded. More grafts were needed to close the fasciotomy in patients followed with VAC. The mean closure time of the fasciotomy was 25.9±3.8 days in the PDS group and 27.3±3.5 days in the VAC group, indicating no significant difference between the groups (p=0.738). There was no significant difference in the rate of wound infection between the two groups (p=0.482). Our study results suggest that more grafts are needed to close the fasciotomy in patients followed with VAC; however, it seems to increase the cost of the treatment.

In Vitro Analysis of Platelet Adhesion, Aggregation, and Surface GP1bα Expression in Stored Refrigerated Whole Blood: A Pilot Study.

Warm, fresh whole blood (WB) has been used by the US military to treat casualties in Iraq and Afghanistan. Based on data in that setting, cold-stored WB has been used to treat hemorrhagic shock and severe bleeding in civilian trauma patients in the United States. In an exploratory study, we performed serial measurements of WB's composition and platelet function during cold storage. Our hypothesis was that in vitro platelet adhesion and aggregation would decrease over time. WB samples were analyzed on storage days 5, 12, and 19. Hemoglobin, platelet count, blood gas parameters (pH, Po2, Pco2, and Spo2), and lactate were measured at each timepoint. Platelet adhesion and aggregation under high shear were assessed with a platelet function analyzer. Platelet aggregation under low shear was assessed using a lumi-aggregometer. Platelet activation was assessed by measuring dense granule release in response to high-dose thrombin. Platelet GP1bα levels were measured with flow cytometry, as a surrogate for adhesive capacity. Results at the 3 study timepoints were compared using repeat measures analysis of variance and post hoc Tukey tests. Measurable platelet count decreased from a mean of (163 + 53) × 109 platelets per liter at timepoint 1 to (107 + 32) × 109 at timepoint 3 (P = .02). Mean closure time on the platelet function analyzer (PFA)-100 adenosine diphosphate (ADP)/collagen test increased from 208.7 + 91.5 seconds at timepoint 1 to 390.0 + 148.3 at timepoint 3 (P = .04). Mean peak granule release in response to thrombin decreased significantly from 0.7 + 0.3 nmol at timepoint 1 to 0.4 + 0.3 at timepoint 3 (P = .05). Mean GP1bα surface expression decreased from 232,552.8 + 32,887.0 relative fluorescence units at timepoint 1 to 95,133.3 + 20,759.2 at timepoint 3 (P < .001). Our study demonstrated significant decreases in measurable platelet count, platelet adhesion, and aggregation under high shear, platelet activation, and surface GP1bα expression between cold-storage days 5 and 19. Further studies are needed to understand the significance of our findings and to what degree in vivo platelet function recovers after WB transfusion.

Healing large Traumatic Tympanic Membrane Perforations Using Vaseline Gauze and Gelfoam Patching Alone.

The aim of this study was to evaluate the effect of vaseline gauze (VG) patching on the treatment of large traumatic perforation of tympanic membrane (TM). 90 patients with traumatic perforation larger than 25% of the TM were randomly allocated into the control group of observation only, VG group, and Gelfoam patch alone group. The closure rate and closure time among the 3 groups were compared at 3 months. In total, 82 large traumatic perforations were analyzed in this study. The closure rates in the control, VG, and gelfoam patch groups were 84.6%, 100.0%, and 89.3%, respectively (P = 0.637). Post-hoc multiple comparisons showed that the difference between the control and VG groups was significant (P = 0.047), but the difference wasn't significant between gelfoam alone and control groups (P = 0.699) or VG groups (P = 0.236). The mean closure times were 5.41 ± 1.47, 2.14 ± 0.93, and 3.00 ± 0.62 weeks for the control, VG, and gelfoam patch groups, respectively (P < 0.001). Post-hoc multiple comparisons showed that the difference was significant between the control and VG groups (P < 0.001) or gelfoam alone group (P < 0.001) or VG and gelfoam groups (P < 0.05). VG improved the closure rate and shortened the closure time compared with observation only, which could be an effective patch material for repairing traumatic lager perforations in the outpatient setting, which is readily available and convenient.

With and without exogenous biological scaffolds for repairing traumatic perforations of tympanic membrane: Randomized clinical trials

ObjectiveThe objective of this study was to compare the efficacy of ofloxacin ear drops, vaseline gauze (VG) and dry gelfoam alone on the large traumatic perforations of tympanic membrane (TM). Material and methodsA randomized prospective analysis was performed for the treatment of traumatic perforation larger than 25 % of the entire TM. The closure rate, closure time, and hearing gain between ofloxacin ear drops, VG and gelfoam alone groups were compared at 3 months. ResultsFinal analysis was performed on 70 patients. The closure rates of perforation in the ofloxacin ear drops, VG, and dry gelfoam patch groups were 100.0 %, 92.0 %, and 87.5 %, respectively (P = 0.41).The mean closure times were 8.67 ± 3.1, 10.65 ± 4.2, and 14.33 ± 7.5 days for the ofloxacin ear drops, VG, and gelfoam patch alone groups, respectively. The closure times among the 3 groups were significantly different (P = 0.003). In addition, there was a significant difference between the ofloxacin ear drops and gelfoam patch alone groups with regard to closure time (P = 0.003), while there was no significant difference between the ofloxacin ear drops and VG groups (P = 0.080) or VG and gelfoam patch groups (P = 0.056).The mean hearing gain was 11.4 ± 2.3 dB for the ofloxacin ear drops group, 11.7 ± 4.1 dB for the VG group, and 12.2 ± 1.6 dB for the gelfoam patch group (P = 0.69). ConclusionsThe repairing of traumatic perforations didn't require an exogenous biological scaffold. Ofloxacin ear drops and VG were a deal material for repairing traumatic perforation in otology clinic, which not only was readily available and inexpensive but also showed faster closure compared with dry gelfoam alone.

A Comparison between Skin Stapler and Polypropylene Sutures in Closing Laparotomy Wounds: A Study of 100 Cases

Objective: Healing of laparotomy wounds is associated with number of factors. The aim of the study was to compare skin stapler and polypropylene sutures in closing laparotomy wounds. Materials and method: This randomized controlled trial study was conducted at the Department of Surgery, Sir Salimullah Medical College Mitford Hospital, Dhaka, Bangladesh. The study duration was 6 months, from July 2010 to December 2010. A total of 100 participants were included in the study, divide in two equal groups of 50 participants. The first group received interrupted suture with 2/0 polypropylene. The other group received skin staples. Results: The mean time for closure with suture and staple were 3.7±SD and 22.5±SD cm/min respectively (p- value&lt;0.05). Rate of wound closure was calculated in cm per minute and materials were compared statistically in pairs by t- test. Wounds were closed five times faster with staples then suture (p&lt;0.001). In relation to post-operative infection, 17 (34%) cases developed wound infection in sutured group and 15 (30%) patients in stapled group. Most of the infection occurred in the emergency contaminated cases. There was no significant association between wound infections and method of skin closure (p&gt; 0.05, chi square= 3.15). Conclusions: Staples were well-liked by operators and resulted in substantial and worthwhile savings in time for wound closure.

Through-the-scope suture closure of peroral endoscopic myotomy mucosal incision sites.

BACKGROUND : Peroral endoscopic myotomy (POEM) is now widely used for esophageal motility disorders including achalasia. Closure of the mucosal incision site is a critical step of the procedure. We evaluated the use of a novel through-the-scope (TTS) suture system for closure of POEM mucosal incision sites. METHODS : We retrospectively reviewed consecutive patients who underwent POEM with TTS suture closure at our institution between February and July 2021. Technical success was defined as complete mucosal incision site closure using TTS suturing, without the need for adjunctive devices. Continuous variables are presented as median (interquartile range [IQR]) or mean (SD). RESULTS : 35 consecutive patients (median age 58 years [IQR 46.5-72]; 54.3 % female) underwent POEM with attempted mucosal closure by TTS suturing. Technical success was achieved in 32 patients (91.4 %) with a mean closure time of 12.4 (SD 6.9) minutes. The median mucosal incision length at time of closure was 2.5 cm (IQR 2-2.5). Overall, 17 patients (53.1 %) required ≥ 2 TTS suture systems and 3 patients (8.6 %) required additional TTS clips to achieve secure mucosal closure. No adverse events were encountered. CONCLUSIONS : TTS suturing was effective and safe for POEM mucosotomy closure. However, prospective comparative trials and cost-effectiveness analyses are warranted before routine adoption.

Comparison of Hasson (Open) and Veress Needle (Closed) Technique of Creating Pneumoperitonium in Laparoscopic Cholecystectomy

Objective: The purpose of this study is to compare the outcomes between hasson (open) and veress needle (closed) technique of creating pneumoperitonium in laparoscopic cholecystectomy. Study Design: Comparative/Randomized study Place and Duration: PHFMC (ZCD 417,Toba Tek Singh). Jun 2019-May 2020 Methods: Ninety patients of both genders with ages 20-75 years were presented in this study. All patients provided written informed consent before having their full demographic information collected, which included their age, gender, and body mass index. All the patients had symptomatic gall stones disease was underwent for laparoscopic cholecystectomy. Patients were categorized into two equal groups. Group I had 45 patients and received veress needle (closed) technique and group II received hasson (open) technique for creating pneumoperitoneum. Post-operatively outcomes in terms of access time , gas leak, visceral injury, vascular injury, need for conversion, umbilical port site hematoma, umbilical port site infection, umbilical port site hernia were assessed and compared among both groups. To analyze the entire set of data, we used the SPSS 24.0 edition. Results: Mean age of the patients in group I was 36.13 ±5.77 years with mean BMI 25.06 ±6.33 kg/m2 and in group II mean age was 37.23 ±6.55 years with mean BMI 25.16 ±4.45 kg/m2 . Majority of the patients 60 (30 in each group) were female. Mean access time in group II was lower 4.78 ±11.43 minutes as compared to group I 6.11±4.12 minutes. Mean closure time in group I was 7.33 ±7.23 minute and in group II mean closure time was 6.03±3.19 minutes. Frequency of gas leak in group I was higher found in 8 (17.8%) cases as compared to group II 3 (6.7%). Visceral injury was greater in group I 3 (6.7%) as compared to group II 1 (2.2%). Vascular injury among both groups was similar 2 (4.4%) and there is no any case found for conversion. Post-operatively complications hematoma, infection and umbilical hernia were greater in group II 4 (8.9%), 2 (4.4%) and 2 (4.4%) as compared to hasson (open) group. Conclusion: Pneumoperitonium was created more quickly and efficiently in laparoscopic cholecystectomy using the hasson (open) approach in this comparative analysis than any other method. When it comes to problems and injuries, the open approach (rather than the closed technique) was determined to be less risky overall.
