Use of monofilament sutures and triclosan coating to protect against surgical site infections in spinal surgery: a laboratory-based study

PurposeWe investigated bacterial propagation through multifilament, monofilament sutures and whether sutures coated with triclosan would exhibit a different phenomenon.MethodsOne centimetre (cm) wide trenches were cut in the middle of Columbia blood Agar plates. We tested a 6 cm length of two Triclosan-coated (PDS plus®, Vicryl plus®) and two uncoated (PDS ®, Vicryl ®) sutures. Each suture was inoculated with a bacterial suspension containing methicillin-sensitive Staphylococcus aureus (MSSA), Escherichia coli (E. coli), Staphylococcus epidermidis, methicillin-resistant Staphylococcus aureus (MRSA) at one end of each suture. The plates were incubated at 36C for 48 h, followed by room temperature for a further 5 days. We established bacterial propagation by observing for any bacterial growth on the Agar on the opposite side of the trench.ResultsBacterial propagation was observed on the opposite side of the trench with both suture types, monofilament PDS and multifilament Vicryl, when tested with the motile bacterium (E. coli). Propagation was not observed on the other side of the trench with the monofilament PDS suture following incubation with MSSA and S. epidermidis, and in 66% of MRSA. With multifilament suture Vicryl, propagation was observed on the other side of the trench in 90% (MSSA), 80% (S. epidermidis), and 100% (MRSA) of plates tested. No bacterial propagation was observed in any of the triclosan-coated sutures (monofilament or multifilament).ConclusionsMonofilament sutures are associated in vitro with less bacterial propagation along their course when compared to multifilament sutures. Inhibition in both sutures can be further enhanced with a triclosan coating.

Laparoscopic myomectomy - The importance of surgical techniques.

Laparoscopy is a routine procedure for benign gynecological tumors. Although the laparoscopic approach for myomas is a common procedure, it can be challenging. To improve outcomes, research regarding port access, suture type, morcellation, and complication management remains ongoing. Myomectomy is the main surgical option for patients seeking uterus-sparing procedures to maintain future fertility. The laparoscopic technique is the most important in these cases, given that possible complications can impact fertility and pregnancy outcomes. Herein, we reviewed and collated the available data regarding different suture techniques, including advantages, difficulties, and possible long-term impacts.

Microbiological Retention on PTFE versus Silk Suture: A Quantitative Pilot Study in Third Molar Surgery

Background: Mandibular third molar (M3M) removal and management of postoperative complications represent a common matter of interest in oral and maxillofacial surgery. This potential quantitative study assessed the ability of two types of surgical sutures, Silk and polytetrafluoroethylene polymer (PTFE), to carry aerobic and anaerobic bacteria on wounds after mandibular third molar surgery, with a collection of the stitches at the suture removal and study in the laboratory on the basis of colony-forming units. Methods: This prospective quantitative study sampled a total of 10 consecutive healthy patients for mandibular third molar surgery at the Oral Surgery School, Dentistry and Dental Prosthodontics, Department of Medical Biotechnologies, University of Siena, Siena, Italy. The mean age of the patients was 31 years (range 25-40 years), seven patients were male and three patients were female. Inclusion criteria were: presence of a partially impacted mandibular third molar. Exclusion criteria were: smoking and diabetes mellitus. Extraction of the mandibular third molar was performed under local anesthesia: after the third molar surgery, two sutures were applied on the surgical site distally to the second mandibular molar: one single 3/0 silk stitch; one single 3/0 PTFE stitch. No sutures were applied on the release incision. Sutures were removed after 7 days and were immediately conserved and sent to the laboratory to be rated on the basis of colony-forming units (CFUs). CFUs were evaluated and reported on GraphPad Prism and transformed into its base 10 logarithm. Data were analyzed with a non-parametric Wilcoxon test, and p-values < 0.05 were evaluated as statistically significant. Results: All the patients attended the suture removal date, and all the sutures were present in the site. None of the surgical sites presented dehiscence. No stitch loss was reported, and no patient reported mouth washing or tooth brushing in the surgery site. All interventions were uneventful and no major complications were reported after M3M surgery. Bacterial retention resulted as statistically greater in silk sutures rather than PTFE sutures, both in Brain Heart Infusion samples (p = 0.003) and Wilkins-Chalgren anaerobe samples (p = 0.002). Conclusions: We found the PTFE suture to be superior to the silk suture in a reduction in the bacterial biofilm in both aerobic and anaerobic evaluations after M3M surgery.

Mini All-Suture Anchors for Repairing the Central Slip of the Extensor Tendon at the Proximal Interphalangeal Joint: A Biomechanical Investigation

This study evaluated 1.0-mm mini suture anchors for repairing the central slip of the extensor mechanism at the proximal interphalangeal joint. Studies have reported a requirement for central slip fixation to withstand 15 N during postoperative rehabilitation exercises and 59 N during forceful contraction. Index and middle fingers from 10 matched pairs of cadaveric hands were prepared with 1.0-mm mini suture anchors with 2-0 sutures or threaded with 2-0 sutures through a bone tunnel (BTP). In total, 10 index fingers from unmatched hands were prepared with suture anchors and fixed to the extensor tendons to evaluate the tendon/suture interface response. Each distal phalanx was secured to a servohydraulic testing machine, and ramped tensile loads were applied to suture or tendon until failure. All anchors for the all-suture bone tests failed because of pullout from the bone (Mean failure force= 52.5+/-17.3 N). Three anchors from the tendon-suture pull out test failed by pullout from the bone and seven failed at the tendon/suture interface (Mean failure force= 49.0+/-10.1 N). The 1.0-mm mini suture anchor provides enough strength for early short-arc motion, but it may not be adequate for forceful contraction in the early postoperative rehabilitation stage. The site of fixation, the type of anchor, and the type of suture used are key factors to consider for early range of motion, after surgery.

Clinical and microbiological comparison of knotless/barbed and silk sutures for impacted third-molar surgery.

Several types of suture materials are available for oral surgery. However, the most used non-resorbable suture in oral surgery is 3/0 silk. The aim of the present study was to compare the effectiveness of knotless/barbed sutures with silk sutures during the postoperative period after the third molar surgery in terms of clinical and microbiological parameters. The study comprised 38 patients who underwent surgical extraction of a mandibular impacted third molar. The patients were divided into two groups. The mucoperiosteal flap was closed using 3/0 knotless/barbed sutures for the test group and 3/0 silk sutures for the control group. The duration of suturing was recorded during surgery. Pain level, postoperative edema, and trismus were measured at 3 and 7 days after surgery. The status of plaque formation on the sutures was scored using the Plaque Index at 3 and 7 days after the surgery. At 7 days, the suture materials were removed and submitted to the laboratory for microbiological analysis. The level of pain during suture removal was also recorded by a Visual Analog Scale. The duration of suturing in the barbed sutures group was found significantly lower than in silk sutures (P<0.05). There was no significant difference between the suture types in terms of trismus and edema at 3 and 7 days after surgery (P>0.05). On the third day after surgery and during suture, removal pain scores were statistically significantly lower in the barbed suture group than in the silk suture group (P<0.05). The Plaque Index values of the barbed sutures were statistically significantly lower than that of the silk sutures at 3 and 7 days after surgery (P<0.05). Aerobic, anaerobic, and aerobic/anaerobic mean colony forming units (CFUs) were statistically significantly lower in the barbed suture group than in the silk suture group (P<0.05). Barbed sutures increase the ease of operation and patient comfort with less postoperative pain than silk sutures. Additionally, less plaque accumulation and lower bacterial colonization were found on the barbed/knotless sutures than on the silk sutures.

Pharyngocutaneous Fistula in Salvage Laryngectomy: Use of the Stapler Versus Manual Suturing Technique.

A pharyngocutaneous fistula (PCF) is the most common complication after salvage total laryngectomy (STL) with an incidence ranging from 5 to 73%, causing an increase in morbidity and delaying the patient's recovery. A surgical technique to prevent PCF formation is the use of the stapler to suture the pharyngeal mucosa. We have reviewed the medical files of 91 patients who had undergone STL, dividing the patients into two groups (manual suture vs. stapler), based on the type of pharyngeal suture performed during the STL. We found 12/49 (24.5%) cases of a PCF in group A (manual) and 5/42 (11.9%) cases of a PCF in group B (stapler). There is a statistically significant difference between the two groups with the patients in group B presenting better results in terms of the reduction of the surgical time, the length of the hospital stay and also in the restarting of oral feeding. The advantages of mechanical suturing with the stapler are reduced surgical times, a lower PCF formation rate, which involves an early removal of the nasogastric tube, and reduced hospitalization times. Further studies with a larger case series will be necessary to confirm the results obtained and to standardize the surgical technique.

Dolor pélvico en mujeres con episiotomía versus mujeres con desgarro perineal de segundo grado

IntroductionPelvic pain is one of the most common pelvic floor dysfunctions in the postpartum period, depending on the degree of injury and the time at which it is assessed. The degree of involvement of a mediolateral episiotomy is similar to that of a second degree perineal tear, therefore it was decided to conduct a study to collect the degree of pain reported using the McGill Pain Questionnaire. Material and methodsAn observational, prospective longitudinal epidemiological study of dynamic cohorts was conducted among 384 women, of whom 255 had a second-degree tear and 129 had undergone an episiotomy. An assessment of the pelvic floor was carried out, together with data collection (performance or not of perineal massage, pelvic floor muscle exercises, presence of Kristeller, type of suture) as well as the degree and type of pain using the McGill Questionnaire, in the immediate puerperium, at six weeks, and six months of postpartum. ResultsIn the immediate puerperium more than 50% of women reported some type of painful sensation, without finding significant differences between both cohorts. However, as the study evolved, there was a progressive decrease in pain in both cohorts. By six weeks postpartum, less than 33% of women reported a painful sensation, considered as absence of pain according to the criteria of the McGill questionnaire. ConclusionThe presence of episiotomy or second degree perineal tear was not related to perineal pain.

Time course of sutural width during the physiological growth from birth to adulthood: CT quantitative and qualitative evaluations of sutural arches.

We performed a retrospective qualitative and quantitative evaluation of the sutural changes during the physiological growth to define the age-related ossification stages of major and minor skull sutures or synchondroses. A total of 390 healthy subjects, examined for cranio-facial trauma and whose CT scans turned out to be normal, were clustered into homogenous age-matched groups ranged from birth to 90years. High-resolution CT was used to assess the degree of sutural closure according to a 3-grade scoring system, the sutural pattern, the width, and the density of the gap calculated as the average of two or three ROIs along each suture/synchondrosis. The identification of a definite pattern depended on the suture's type, the closure degree, and the width of the gap (p < 0.001). The interdigitation process was more intricate for most of vault sutures than the skull base sutures/synchondroses. Closing grades 1, 2, and 3 were associated to an identifiable sutural pattern and the cutoff value of 1.45mm of the gap width allowed to detect an identifiable sutural pattern with the best combination of sensitivity (97%) and specificity (98%). Age and sutural closing degree were inversely related to gap width while positively related to the gap density (p < 0.001). The sutural ossification is an age-related process, distinctive for each suture, and synchondrosis; it occurs neither according to a predefined order along sutural arches nor following a sequential distribution in the cranial fossae, and some sutures continued their growth process during lifetime.

Reduction of recurrence by peritoneal thermal injury in laparoscopic percutaneous extraperitoneal closure of internal ring for inguinal hernia in children.

To evaluate the impact of peritoneal thermal injury (PTI) in the reduction of recurrence incidence in laparoscopic percutaneous extra-peritoneal closure of internal ring (LPEC) for pediatric inguinal hernia (PIH) in children. Medical records of patients undergoing LPEC for PIH at our center were reviewed and divided into 2 groups: Group A (period from June 2017 to December 2017)-without PTI and Group B (period from January 2018 to December 2018) with PTI. The surgical technique and the type of suture used for LPEC were the same for both groups. The outcomes of the two groups were analyzed and compared. 277 patients with 283 IHs in group A were compared to 376 patients with 389 IHs in group B. There were no significant differences between the two groups in terms of age, gender, uni- or bilateral hernia. At a median follow-up period of 48months, there was no hydrocele, suture granuloma, testicular atrophy, or iatrogenic cryptorchidism in both groups. The recurrence rate in group A was 6.4%, significantly higher than 1.8% in group B (p = 0.002). Our study showed that PTI in LPEC for PIH is safe and associated with a significant reduction of recurrence incidence.

International, prospective cohort study comparing non-absorbable versus absorbable sutures for skin surgery: CANVAS service evaluation.

Absorbable or non-absorbable sutures can be used for superficial skin closure following excisional skin surgery. There is no consensus among clinicians nor high-quality evidence supporting the choice of suture. The aim of the present study was to determine current suture use and complications at 30 days after excisional skin surgery. An international, prospective service evaluation of adults undergoing excision of skin lesions (benign and malignant) in primary and secondary care was conducted from 1 September 2020 to 15 April 2021. Routine patient data collected by UK and Australasian collaborator networks were uploaded to REDCap©. Choice of suture and risk of complications were modelled using multivariable logistic regression. Some 3494 patients (4066 excisions) were included; 3246 (92.9 per cent) were from the UK and Ireland. Most patients were men (1945, 55.7 per cent), Caucasian (2849, 81.5 per cent) and aged 75-84 years (965, 27.6 per cent). The most common clinical diagnosis was basal cell carcinoma (1712, 42.1 per cent). Dermatologists performed most procedures, with 1803 excisions (44.3 per cent) on 1657 patients (47.4 per cent). Most defects were closed primarily (2856, 81.9 per cent), and there was equipoise in regard to use of absorbable (2127, 57.7 per cent) or non-absorbable (1558, 42.2 per cent) sutures for superficial closure. The most common complications were surgical-site infection (103, 2.9 per cent) and delayed wound healing (77, 2.2 per cent). In multivariable analysis, use of absorbable suture type was associated with increased patient age, geographical location (UK and Ireland), and surgeon specialty (oral and maxillofacial surgery and plastic surgery), but not with complications. There was equipoise in suture use, and no association between suture type and complications. Definitive evidence from randomized trials is needed.

Comparison of purse string suture versus transverse mattress suture to secure haemostasis in thinned out caesarean section scars.

Objective: To compare the effectiveness of two types of haemostatic sutures to secure bleeding in thinned out caesarean section scars. Study Design: Comparative Interventional Study. Setting: CMH Okara, Pakistan. Period: September 2019 to September 2021. Material &amp; Methods: Patients were divided in four categories. Category I was previous one scar patients while category II was previous two scars patients. Similarly, categories III and IV were previous three and four scar patients respectively. In each category hemostasis was secured either by purse string suture or transverse mattress sutures. Hemostasis whether achieved with difficultly or without difficulty was assessed and time utilized was also calculated. Results: In patients with previous one caesarean section 3 out of 15 (20%) had haemostatic difficulty with both purse string suture and horizontal mattress suture. In patients with previous two caesarean sections the number was 5 (33.33%) and 6 (40%) in both purse string and horizontal mattress suture respectively. In patients with previous three caesarean sections there were 7 (46.66%) women who had difficulty in haemostasis in both group I and II. The average time to achieve the procedure in group I (purse string suture) was 3.25 minutes while it was 7.5 minutes in group II (Horizontal mattress sutures). There was two times difference in time consumption between two groups. Conclusion: Purse string suture is more effective, convenient and quicker to apply as compared to transverse mattress sutures for haemostasis in thinned caesarean section scars.

Modification of the properties of a suture thread with a tough gel coating: Abaseline ex-vivo study.

The mechanical properties of sutures are important for wound closure and meniscus repair. A tough gel coating technology has been developed to modify and functionalize sutures, but its effects on suture degradation remain unexplored. Our aim is to investigate how a tough gel coating mediates the properties of the suture. The Polyglactin910 (Vicryl) suture was chosen because it is widely used, strong, easy to handle, and degradable. This study compared six pristine Vicryl sutures and six coated Vicryl sutures at 0, 2, 4, and 6 weeks. All the sutures were soaked in phosphate-buffered saline (PBS), to mimic degradation in physiological conditions, and tensile strength was tested at each time point. The pH of the soaking mediums was measured weekly and compared at 4, 5, and 6 weeks. No significant difference (p = 0.059 and p = 0.576) was found between the absolute and normalized breaking force of coated and pristine Vicryl sutures at 0, 2, 4, and 6 weeks. After 4 weeks of immersion, the soaking medium became more acidic for both suture types. The decrease in pH was less significant for coated Vicryl sutures than for pristine ones (p < 0.001) at 4, 5, and 6 weeks of immersion. Although coating does not affect the strength of Vicryl sutures soaked in PBS, it can effectively act as a buffer to the acidic environment caused by suture degradation, which could help reduce inflammation. Hydrogel coating is a promising technology to modify suture characteristics.

Comparison of the Effectiveness Between Conventional and Modified Cinch Suture Techniques in LeFort I Osteotomy: A Systematic Review and Meta-Analysis of Randomized Control Trials.

LeFort I osteotomy changes the morphology of the nose. The cinch suture has been proven to prevent the increase in nasal base and alar width. Different types of cinch sutures have been proposed. However, their effectiveness is unclear. The aim of this study was to compare the surgical outcomes between conventional and modified cinch techniques through a systematic review and meta-analysis of randomized control trials (RCTs). We performed systematic search from Embase, PubMed, and the Cochrane Library according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement up to March 2021. The surgical techniques of different cinch sutures were reviewed, and the outcomes of nasal alar width and alar base width were compared between modified and conventional methods. A total of 4 eligible RCTs were included in this meta-analysis. Pooled data showed no significant difference in alar base width change between modified and conventional methods (mean difference, -0.37; 95% confidence interval, -1.32 to 0.57; P = 0.44). Pooled data of 3 studies also showed no significant difference in nasal alar width change (mean difference, -0.11; 95% confidence interval, -1.18 to 0.95; P = 0.83). Based on the current data pooled from the available RCTs, no significant difference was found between the conventional cinch technique and the modified technique.

The functional anatomy of the cornea of the Shorthead lamprey, Mordacia mordax (Mordaciidae, Agnatha): a comparison between downstream and upstream migrants.

The Shorthead lamprey Mordacia mordax (Mordaciidae, Agnatha) represents one of the earliest stages in vertebrate evolution. This study investigates the ultrastructural anatomy of the cornea, iris and anterior chamber in the eyes of this species in both the downstream and upstream migrant phases of its protracted lifecycle to assess the morphological and quantitative changes associated with growth, corneal function and vision. Using light and both scanning and transmission electron microscopy, the cornea is found to be divided into dermal and scleral components separated by a mucoid layer. A range of distinguishing corneal features are compared in the two adult phases of the lifecycle including epithelial microprojections, mucus-secreting epithelial cells, the number, thickness, formation and level of branching and anastomosing of collagen lamellae, the type and distribution of vertical sutures, the structure of the mucoid layer and annular ligament and the number and distribution of a large number of basement membranes throughout the cornea. Significant differences are found between the two phases, which are thought to reflect adaptations to the variable environmental conditions encountered throughout this species' lifecycle. The study provides insights into the evolutionary pressures on extant representatives of the earliest stages in the evolution of the vertebrate eye. This article is protected by copyright.

Permanent Compared With Absorbable Suture in Apical Prolapse Surgery: A Systematic Review and Meta-analysis.

To explore how permanent compared with absorbable suture affects anatomic success in native tissue vaginal suspension (uterosacral ligament suspension and sacrospinous ligament suspension) and sacrocolpopexy with mesh. MEDLINE, EMBASE, and ClinicalTrials.gov were searched through March 29, 2022. Our population included women undergoing apical prolapse surgery (uterosacral ligament suspension and sacrospinous ligament suspension and abdominal sacrocolpopexy). Our intervention was permanent suture for apical prolapse surgery, and our comparator was absorbable suture. We determined a single anatomic success proportion per study. Adverse events collected included suture and mesh exposure, surgery for suture and mesh complication, dyspareunia, and granulation tissue. Abstracts were doubly screened, full-text articles were doubly screened, and accepted articles were doubly extracted. Quality of studies was assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. In single-arm studies using either permanent or absorbable suture, random effects meta-analyses of pooled proportions were used to assess anatomic success. In comparative studies investigating both suture types, random effects meta-analyses of pooled risk ratios were used. Of 4,658 abstracts screened, 398 full-text articles were assessed and 63 studies were included (24 vaginal suspension [13 uterosacral ligament suspension and 11 sacrospinous ligament suspension] and 39 sacrocolpopexy). At 2-year follow-up, there was no difference in permanent compared with absorbable suture in uterosacral ligament suspension and sacrospinous ligament suspension (proportional anatomic success rate 88% [95% CI 0.81-0.93] vs 88% [95% CI 0.82-0.92]). Similarly, at 18-month follow-up, there was no difference in permanent compared with absorbable suture in sacrocolpopexy (proportional anatomic success rate 92% [95% CI 0.88-0.95] vs 96% [95% CI 0.92-0.99]). On meta-analysis, there was no difference in relative risk (RR) of success for permanent compared with absorbable suture for uterosacral ligament suspension and sacrospinous ligament suspension (RR 1.11, 95% CI 0.93-1.33) or sacrocolpopexy (RR 1.00, 95% CI0.98-1.03). Success rates were similarly high for absorbable and permanent suture after uterosacral ligament suspension, sacrospinous ligament suspension, and sacrocolpopexy, with medium-term follow-up.

Arthroscopy Revision of Medial Meniscus Posterior Root (MMPR) Reconstruction Using Gracillis Tendon Graft. A Case Report

The techniques for medial meniscal posterior roots (MMPR) repair can vary in relationship to the surgical approach, type of suture, device used, and fixation technique. Anatomic reduction, meniscal root fixation, and prevent extursion are possible by the trans-tibial pull-out repair procedure for MMPR tears. But it has been found that it has a substantially weaker than the natural root with unsactisfactory healing rates. Objective: We purposed this technique to reduce the failure of meniscus repair with a more anatomical, better healing and reproducible outcome Case Presentation: A 60-year-old female patient with Medial Meniscus Posterior Root tear LaPrade classification type 2. She had arthroscopic transtibial pull-out meniscal root repair using Ethibond No. 5 non-absorbable suture material. Six months after surgery, she had retear on MMPR and we performed the arthroscopic MMPR reconstruction with gracilis tendon graft. 3 months after surgery, patient has a good function and MRI evaluation. Conclusion: This arthroscopic medial meniscus posterior root reconstruction using gracilis graft is provide an anatomical repair, a more strong with a biological healing than previous repair techniques.

Stabilizacija preloma distalnog okrajka ključne kosti Neer IIB tipa upotrebom Tightrope sistema - prikaz slučaja

Introduction: Fractures of the distal end of the clavicle account for 10% - 30% of all fractures of this bone, however, they account for as many as 50% of nonunions and malunions in clavicle fractures. Of all distal clavicle fractures, the highest percentage of complications appertain to Neer type IIB fractures. The aim of this paper is to describe the case of a female patient with a Neer type IIB clavicle fracture treated by fracture reduction and flexible stabilization of the coracoclavicular joint using the TightRope system. Case report: A 48-year-old female patient, injured in a traffic accident while driving a car, suffered a Neer type IIB fracture of the distal edge of the left clavicle. Three days after the injury, the patient underwent indirect stabilization surgery of the coracoclavicular joint by fixation, with the application of the TightRope system. Rehabilitation began on the first postoperative day and was completed three months after surgery, with the achievement of full range of motion in the left shoulder, return of muscle tone and strength of the shoulder muscles, followed by a return to everyday life and work activities, as before the injury. Conclusion: Although no gold standard exists in the operative treatment of the above-described injuries, the indirect method of stabilization and flexible fixation of the coracoclavicular joint, using different types of sutures, achieves good to excellent results. Comparing this method with other described techniques indicates that it has a better functional result, which is achieved faster with a lower complication rate. Our patient's functional results contribute to literature data and yet again demonstrate the effectiveness of this type of treatment for these complex injuries.

Effects of Using Barbed Suture in Myomectomy on Adhesion Formation and Adverse Pregnancy Outcome.

There is still concern regarding postoperative adhesion formation and adverse effects on pregnancy outcomes caused by barbed suture (BS) after myomectomy. The aim of this study was to compare the postoperative adhesion and pregnancy outcomes between conventional suture (CS) and BS after minimally invasive myomectomy (MIM) by robotic myomectomy (RM) or laparoscopic myomectomy (LM). The medical records of 94 women who had undergone MIM with CS and 97 who had undergone MIM with BS and achieved pregnancy were reviewed. Postoperative adhesion was evaluated following cesarean section. The number of removed myomas was greater (5.3 ± 4.6 vs. 3.5 ± 3.1, p = 0.001) and the size of the largest myoma was larger (7.0 ± 2.2 vs. 5.8 ± 2.7 cm, p = 0.001) in the BS group relative to the CS group. A total of 98.9% of patients in the CS group and 45.4% in the BS group had undergone LM (p &lt; 0.001), while the others underwent RM. There was no significant difference in the presence of postoperative adhesion at cesarean section between the BS and CS groups (45.5 vs. 43.7%, p = 0.095). Additionally, there were no intergroup differences in pregnancy complications such as preterm labor, placenta previa, accrete or abruption. Note also that in our logistic regression analysis, the suture type (BS or CS) was excluded from the independent risk factors regarding postoperative adhesion formation. Our data indicated that the incidence of postoperative adhesion after MIM with BS was similar when compared with CS. Also it seems that the suture type does not have a significant effect on pregnancy outcomes.
