RESUMO
Williams syndrome was first reported by Williams and Beuren in 1961-1962. It is a genetic disorder that is caused by a sporadic microdeletion of chromosome 7, which includes the elastin gene. The development of gastrointestinal pathology, such as diverticular disease, is associated with the deletion of this specific gene. Almost one-third of patients with Williams syndrome develop diverticular disease. The first episode of diverticulitis appears in 8% of patients, diagnosed with Williams syndrome, before the age of 40. According to the literature, in the case of complicated diverticulitis (Hinchey III) in patients with WS, the treatment is mainly surgical resection of sigmoid and colostomy (Hartmann procedure) or anastomosis. We present an interesting case with a 31-year-old male, with Williams syndrome and Hinchey III diverticulitis, who underwent laparoscopic lavage and primary closure of the perforation. To our knowledge, this is the first case in literature that a patient with Williams syndrome and complicated diverticulitis (Hinchey III) was treated this way and the results until now are encouraging.

RESUMO
Nowadays, endoscopic submucosal dissection (ESD) is commonly performed for the removal of large gastrointestinal lesions. Endoscopic mucosal defect closure after ESD is vital to avoid adverse events. In recent years, many innovative instruments have emerged and proved to be beneficial. In this paper, we conducted a thorough literature review and summarized the closure methods for large-size post-ESD mucosal defects over decades. We separated these methods into five categories based on the operational principle: "side closure" method, "ring closure" method, "layered closure" method, "hand suturing closure" method, and "specially designed device closure" method. Side closure with clips assisted by instruments such as threads or loops is applicable for each segment of the gastrointestinal tract to prevent postoperative bleeding. If the defect tension is too large to close with the traditional side closure methods, zigzag closure and ring closure could be applied to gather the bilateral defect edges together and achieve continuous closure. In the stomach and rectum with a high risk of submucosal dead space between the submucosa and muscular layers, side closure methods with muscle layer grasping clip or layered closure methods could enable the involvement of the deep submucosa and muscle layers. The ring closure method and specially designed devices including over-the-scope clip, Overstitch, and X-tack could resolve perforation effectively. Individual closure method requires endoscope reinsertion or sophisticated operation, which may be limited by the deep location and the narrow lumen, respectively. Although specially designed devices are expected to offer promising prospectives, the cost-effectiveness remains to be a problem.

BACKGROUND AND AIMS: Fully covered self-expandable metal stents (FCSEMSs) are widely used in benign upper gastrointestinal (GI) conditions, but stent migration remains a limitation. An over-the-scope clip (OTSC) device (Ovesco Endoscopy) for stent anchoring has been recently developed. The aim of this study was to evaluate the effect of OTSC fixation on SEMS migration rate. METHODS: A retrospective review of consecutive patients who underwent FCSEMS placement for benign upper GI conditions between 1/2011 and 10/2022 at 16 centers. The primary outcome was rate of stent migration. The secondary outcomes were clinical success and adverse events. RESULTS: A total of 311 (no fixation 122, OTSC 94, endoscopic suturing 95) patients underwent 316 stenting procedures. Compared to the no fixation (NF) group (n=49, 39%), the rate of stent migration was significantly lower in the OTSC (SF) (n=16, 17%, p=0.001) and endoscopic suturing (ES) group (n=23, 24%, p=0.01). The rate of stent migration was not different between the SF and ES groups (p=0.2). On multivariate analysis, SF (OR 0.34, CI 0.17-0.70, p<0.01) and ES (OR 0.46, CI 0.23-0.91, p=0.02) were independently associated with decreased risk of stent migration. Compared to the NF group (n=64, 52%), there was a higher rate of clinical success in the SF (n=64, 68%; p=0.03) and ES group (n=66, 69%; p = 0.02). There was no significant difference in the rate of adverse events between the three groups. CONCLUSION: Stent fixation using OTSC is safe and effective at preventing stent migration and may also result in improved clinical response.
RESUMO
BACKGROUND: Knee joint osteoarthritis (OA)-related meniscal tears are still sometimes treated in centers by arthroscopic partial meniscectomy (APM), which is then followed by a solitary physical therapy regimen. OBJECTIVE: The present study was conducted to compare the efficacy of intra-articular injection of ozonized platelet-rich plasma (PRP) and hyaluronic acid following arthroscopic suturing, and APM to treat meniscal tear degenerative type. METHODS: In a randomized trial of prospective comparative research, 104 patients, all of whom had meniscal tears due to OA of the knee, were randomly divided into two groups. The participants in Group A (55 patients) were given intra-articular ozonized PRP and hyaluronate therapeutics, following arthroscopic suturing of meniscal tear treatment (ASMT) of degenerative knee joint OA. Group B (49 patients) was prepared for APM alone. Both groups were followed by physical therapy and a follow up visit throughout 12, 24, and 36 months. The WOMAC and Lequesne scores were evaluated. RESULTS: At every follow up visit for 6, 12, and 24, months, there was a significant decline in the mean of WOMAC and Lequesne scores in Groups A and B relative to baseline. Additionally, Group A significantly (P<0.0001) outperformed Group B at 12, 24, and 36 months for both Lequesne's and WOMAC scores. There were infection, stiffness, and widespread OA knee degeneration detected in Group B while no serious adverse effects were observed in Group A. CONCLUSION: The study's findings demonstrated that physical and intra-articular orthobiological ozonized PRP and hyaluronate therapies were more effective than APM in treating degenerative knee joint OA.
RESUMO
Endoscopic closure is an essential technique to perform safe advanced endoscopy. Without appropriate closure of a defect, patients can experience spillage of fecal contents into the peritoneal cavity resulting in abdominal sepsis. The essential components to performing endoscopic closure are assessing the defect appropriately and choosing the correct closure technique. Assessing the defect involves five separate elements: timing, size, depth, shape, blood flow, and location in the colon or rectum. Understanding how each of these elements contributes toward a successful closure allows an endoscopist to choose the proper technique for closure. There have been many types of closure techniques described in the literature but the most common are through the scope clips, over the scope clips, and endoscopic suturing. There are advantages and disadvantages of each of these closure techniques. In this manuscript, we will discuss these common techniques as well as some additional techniques and the situations where they can be employed.
RESUMO
This article provides an overview of the techniques for closure of the mucosal entry point following advanced procedures in the third space. The outbreak of natural orifice transluminal endoscopic surgery (NOTES) has significantly impacted the treatment of various benign and malignant conditions. Reliable and secure closure of the mucosal entrance is essential for avoiding serious adverse events. Although small defects are typically closed using through-the-scope clips (TTSCs) or over-the-scope clips (OTSCs), challenges may occur with larger or transmural defects. Alternative methods, such as specialised stitches and full-thickness suturing systems, have been developed to address these challenges with promising results. Each method has its own pros and cons, and the choice of closure technique depends on various factors such as anatomical location, endoscopist expertise, costs, and clinical context. By understanding the technical specifications of each closure device, endoscopists can make decisions that enhance patient outcomes and minimise the risk of complications associated with the approximation of defect edges. Continued research is essential to optimise the evolution of newer closure devices and techniques for advancing NOTES.

BACKGROUND: Previous research has strongly supported the utility of spaced learning in enhancing memory, but its effectiveness in complex surgical procedures has largely been unexplored. The main objective of this study was to evaluate whether, in comparison to concentrated learning, spaced learning improves the short-term acquisition and long-term retention of cosmetic suturing skills as outcomes of surgical resident training courses. METHODS: This randomized controlled trial was conducted from February 2023 to June 2023. Surgical residents were recruited from a teaching hospital in Guangzhou, China. The participants were randomly assigned at a 1:1 ratio to either the spaced training group (40 min of training followed by a 20-minute break) or the concentrated training group (3 h of continuous training), in which they received one-on-one training for cosmetic suturing skills. The short-term acquisition and long-term retention outcomes were evaluated by three independent raters using an objective scoring scale to assess the participants' cosmetic suturing skills before the training (pretraining test), within one hour after the training (posttraining test), and three months after the completion of the training (follow-up test). The score for each participant was calculated as the average of three independent scores. RESULTS: The study included 23 surgical residents, 12 in the spaced training group and 11 in the concentrated training group. The pretraining test revealed no significant difference between the groups. However, in the post-training test, the spaced training group achieved a significantly higher total score than did the concentrated training group (74.06 ± 5.87 vs. 63.43 ± 10.73, p = 0.0070). Specifically, the suture technique scores were 28.46 ± 1.78 and 22.85 ± 3.75, respectively, which were significantly different (p = 0.0002). During the long-term follow-up test, the spaced training group consistently outperformed the concentrated training group by having significantly higher total (75.60 ± 4.78 vs. 60.68 ± 10.40, p = 0.0001), suture quality (32.26 ± 4.01 vs. 26.23 ± 4.16, p = 0.0019), suture technique (28.68 ± 2.63 vs. 22.18 ± 3.94, p = 0.0001), and suturing time scores (14.67 ± 1.15 vs. 12.27 ± 6.07, p = 0.0460). CONCLUSIONS: Incorporating the principles of spaced learning into the instructional process of obtaining cosmetic suture skills for surgical residents not only significantly enhances short-term skill improvement but also contributes to the long-term retention of training outcomes.
During the post-training test conducted to evaluate short-term impacts, the spaced training group showed notably elevated overall scores, particularly in the domain of suture technique, compared to the concentrated training group.In the long-term follow-up test, the spaced training group achieved significantly higher scores on the overall test, suture quality, suture technique, and suturing time than the concentrated training group.By incorporating the principles of spaced learning into the instructional process of cosmetic suture skills for surgical residents, not only does it significantly enhance short-term skill improvement, but it also contributes to the long-term retention of training outcomes.

OBJECTIVES: The risk of postoperative bleeding is high after gastric endoscopic submucosal dissection (ESD) in patients continuously treated with antithrombotic agents (ATAs). The effectiveness of endoscopic hand suturing (EHS) on bleeding after gastric ESD was investigated in patients at high risk of delayed bleeding. METHODS: Patients with neoplasms ≤2 cm who underwent gastric ESD and continued to receive perioperative ATAs were enrolled in this multicenter phase II study. The mucosal defect was closed with EHS after removing the lesion. Postoperative bleeding rate was assessed for 3-4 postoperative weeks as a primary outcome measure. The technical success of EHS and adverse events were also assessed. Based on expected and threshold postoperative bleeding rates of 10% and 25%, respectively, we aimed to include 48 patients in the study. RESULTS: A total of 49 patients were enrolled in the study, and 43 patients were finally registered as the per-protocol set. The postoperative bleeding rate was 7.0% (3/43 patients; the upper limit of one-sided 95% confidence interval [CI], 17.1% and 97.5% CI, 19.1%). The upper limits of the CI were below the threshold value (25%), and the postoperative bleeding rate was below the expected value (10%). The technical EHS success rate, closure maintenance rate on postoperative day 3, and postoperative subclinical bleeding rate were 100%, 83%, and 2%, respectively. No severe adverse events related to EHS were observed. CONCLUSIONS: Endoscopic hand suturing may prevent postoperative bleeding in patients undergoing gastric ESD while being treated continuously with ATAs (UMIN000038140).
RESUMO
Inguinal hernia repair is one of the most frequently performed procedures in pediatric surgery. Treatment methods include classical open repair and laparoscopic approach. In this report we analyze a case of a 14-month-old boy with Loeys-Dietz syndrome treated for an inguinal hernia with laparoscopic percutaneous internal ring suturing (PIRS). Two weeks post-operatively the patient was diagnosed with a recurrence of the hernia complicated by an intestine strangulation. As a re-operation of the hernia, the Lichtenstein method was applied successfully. We analyzed the literature to determine the safety and possible contradictions of the PIRS procedure, with particular emphasis on patients with comorbidities such as connective tissue disorders. We conclude that in the PIRS procedure, despite its safety, feasibility and low complication rate in healthy patients, too few studies were made to draw similar conclusions for patients with comorbidities such as connective tissue disorders.
RESUMO
Background and Aims: Endoscopic sleeve gastroplasty (ESG) is a minimally invasive bariatric procedure to induce weight loss through restrictive physiology. This study was designed to evaluate the fluoroscopic measurement of gastric dimensions after ESG as a predictor of Total Body Weight Loss (TBWL) over time. Methods: Post-ESG patients were enrolled prospectively between August 2013 and August 2019. An upper gastrointestinal (GI) fluoroscopy was obtained within 7 days after the procedure. Two blinded, independent radiologists reviewed fluoroscopic images and measured the gastric lumen transverse diameter in three separate areas of the fundus, body, and antrum. The primary outcome was achieving a TBWL of ten percent or more after ESG. Results: In total, 162 patients were included in the analysis (65% female) and had a mean body mass index (BMI) of 39 ± 6 at baseline. Patients had a mean maximum TBWL of 16.5 ± 8.3%. Respectively, 92%, 75%, and 50% of patients achieved a TBWL of 5%, 10%, or 15% or more. The mean post-procedural UGI gastric fundus/antrum transverse measurement ratio was 1.2 ± 0.6. A higher fundus-to-antrum ratio was significantly associated with a TBWL of 10% or more during follow-up in the multivariable model (OR 2.49, 95% CI 1.31-4.71; p-value 0.005). The prediction score based on the fundus-to-antrum ratio hd an area under the ROC curve of 0.79 (95% CI 0.75-0.83) for predicting a TBWL of 10% or more during follow-up. Conclusions: Measuring gastric the fundus/antrum ratio within one week of endoscopic sleeve gastroplasty (ESG) is a consistent and independent predictive measure of sustained TBWL during long-term follow-up.
RESUMO
BACKGROUND: To develop and maintain suturing skills, clinical exposure is important. When clinical exposure cannot be guaranteed, an adequate training schedule for suturing skills is required. This study evaluates the effect of continuous training, 'reflection before practice' and self-assessment on basic open suturing skills. METHODS: Medical students performed four basic suturing tasks on a simulation set up before ('pre-test') and after their surgical rotation ('after-test'). Participants were divided in three groups; the 'clinical exposure group' (n = 44) had clinical exposure during their rotation only, the 'continuous training group' (n = 16) completed a suturing interval training during their rotation and the 'self-assessment group' (n = 16) also completed a suturing interval training, but with the use of reflection before practice and self-assessment. Parameters measured by a tracking system during the suturing tasks and a calculated 'composite score' were compared between groups and test-moments. RESULTS: A significantly better composite score was found at the after-test compared to the pre-test for all groups for all basic suturing tasks (0.001 ≤ p ≤ 0.049). The self-assessment group scored better at the pre-test than the other two groups for all tasks, except for 'knot tying by hand' (0.004 ≤ p ≤ 0.063). However, this group did not score better at the after-test for all tasks, compared to the other two groups. This resulted in a smaller delta of time ('transcutaneous suture', p = 0.013), distance ('Donati suture' and 'intracutaneous suture', 0.005 ≤ p ≤ 0.009) or composite score (all tasks, except for knot tying by hand, 0.007 ≤ p ≤ 0.061) in the self-assessment group. CONCLUSION: Reflection before practice and self-assessment during continuous training of basic open suturing tasks, may improve surgical skills at the start of the learning curve.

Background and Objectives: Despite numerous described techniques, laparoscopy has yet to replace open surgery as the gold standard for inguinal hernia (IH) repair in children. This may be due to many variables, including the lack of long-term follow-up and concern for increased recurrence. In this study, we present our long-term follow-up data on children undergoing percutaneous internal ring suturing (PIRS) for IH repair. Materials and Methods: This retrospective cohort study included children who underwent PIRS for IH between May 2013 and May 2021 at three tertiary care institutions, with at least three years of follow-up. Age at surgery, side of IH, presence of contralateral patent processus vaginalis, surgical and anesthesia time, and complications were noted. Parents were contacted to enquire about long-term complications, such as recurrence. Results: Long-term follow-up (average 6.9 ± 2.3 years) was available for 714 patients. For unilateral and bilateral procedures, the average surgical time was 13.6 ± 5.4 and 19.9 ± 3.0, and the average anesthesia time was 27.7 ± 12.9 and 33.9 ± 14.1 min, respectively. Complications were seen in 0.84% of patients and 1.2% of procedures, and recurrence was observed in 0.98% of patients and 0.78% of procedures. Conclusions: Our study, with a nearly 7-year follow-up, provides substantial evidence that PIRS is a safe and effective technique for IH repair in children, with low recurrence and complication rates. Despite the study's retrospective nature and limited sample size, it contributes valuable data supporting the use of PIRS in pediatric IH repair.

INTRODUCTION: Inguinal hernia repair is one of the most common surgeries in children. Recently, the use of minimally invasive techniques for inguinal hernia repair has increased in children. Laparoscopic percutaneous internal ring suturing (PIRS) is a technique described for paediatric inguinal hernia repair. The primary objective of this study is to demonstrate the efficacy and reliability of PIRS in paediatric patients through a comparative analysis with an open method. METHODS: Between January 2017 and June 2023, records of patients who underwent surgery for inguinal hernia were retrospectively reviewed. In total 126 patients were included in the study. They were divided into two groups: 33 patients underwent PIRS (group 1) and 93 patients underwent open repair (group 2). Operation time, cost and complications were compared. RESULTS: The mean age of the 126 patients was 3.23 ± 2.4 years. The mean unilateral operative time was 25.13 ± 5.32min in group 1 and 30.28 ± 4.73min in group 2, and there was a statistically significant difference in operative time (p < 0.001). Two patients in group 1 underwent surgery owing to patent processus vaginalis, whereas three patients in group 2 underwent surgery owing to metachronous hernia. There were no major complications such as bleeding requiring surgical intervention or conversion to an open approach during surgery in group 1. No recurrent hernia was observed in any of the 126 patients. CONCLUSIONS: PIRS offers a safe, easy-to-learn method with low complication rates. PIRS has a distinct advantage over open surgical repair because of its capacity to evaluate the contralateral inguinal ring.
RESUMO
Introduction There is general agreement that a thick zone of the keratinized tissues around implants promotes accurate prosthetic procedures, permits oral hygiene maintenance, resists recession, and enables esthetic blending with surrounding tissues. A new procedure called Choukroun's technique has been suggested, and it consists of a combination of horizontal apical mattress suture with regular suture to increase the keratinized tissue in the mandibular arch during the first stage after implantation. The proposed procedure has not been evaluated yet in a cohort of patients. Therefore, this prospective study aimed to evaluate the impact of Choukroun's technique on the width and thickness of the keratinized gingiva after oral surgery. Materials and methods A one-group prospective cohort study was conducted on patients referred to the Department of Oral and Maxillofacial Surgery at the Dental College of Al-Wataniya Private University who had been referred to undergo dental implant surgery. The inclusion criteria for the study group were as follows: patients with mandibular missing teeth, good oral health, good general health, 18-70 years old, at least 1 mm thickness of keratinized gingiva, and at least 1 mm width of the attached gingiva. A total of 14 patients aged 27-67 years were included in the study. After inserting the dental implants, the suturing was accomplished according to Choukroun's method. The width and thickness of the keratinized gingiva were assessed before surgery and at one and two months post-surgery. Repeated measures analysis of variance (ANOVA) was applied to detect significant differences between assessment times. Results The study sample comprised 14 patients, of which four were females (28.6%) and 10 were males (71.4%). Patients' ages ranged from 27 to 67 years, with a mean age of 54.86 ± 11.73 years. The surgical procedure was performed in three different regions: the upper posterior teeth with four patients (28.6%), the upper anterior teeth with three patients (21.4%), and the lower posterior teeth with seven patients (50%). The mean gingival width before surgery was 5.78 mm, whereas the mean gingival thickness was 2.82 mm. There was no significant difference between the three evaluation times in the mean gingival width (P=0.222), and there was a significant difference between the three evaluation times in the mean gingival thickness (P<0.001). The mean mean gingival thickness one month after surgery was significantly greater than its mean value before surgery (mean difference: 0.749 mm). Additionally, the mean gingival thickness two months after surgery was significantly greater than its mean value before (mean differences: 0.636 mm). Conclusions Using horizontal apical mattress sutures (Choukroun's technique) does not provide any advantage in increasing the width of the keratinized gingiva. However, it does lead to an increase in the thickness of keratinized gingiva in the surgical area. Therefore, the use of horizontal apical mattress sutures is recommended.
RESUMO
BACKGROUND: Robotic suturing training is in increasing demand and can be done using suture-pads or robotic simulation training. Robotic simulation is less cumbersome, whereas a robotic suture-pad approach could be more effective but is more costly. A training curriculum with crossover between both approaches may be a practical solution. However, studies assessing the impact of starting with robotic simulation or suture-pads in robotic suturing training are lacking. METHODS: This was a randomized controlled crossover trial conducted with 20 robotic novices from 3 countries who underwent robotic suturing training using an Intuitive Surgical® X and Xi system with the SimNow (robotic simulation) and suture-pads (dry-lab). Participants were randomized to start with robotic simulation (intervention group, n = 10) or suture-pads (control group, n = 10). After the first and second training, all participants completed a robotic hepaticojejunostomy (HJ) in biotissue. Primary endpoint was the objective structured assessment of technical skill (OSATS) score during HJ, scored by two blinded raters. Secondary endpoints were force measurements and a qualitative analysis. After training, participants were surveyed regarding their preferences. RESULTS: Overall, 20 robotic novices completed both training sessions and performed 40 robotic HJs. After both trainings, OSATS was scored higher in the robotic simulation-first group (3.3 ± 0.9 vs 2.5 ± 0.8; p = 0.049), whereas the median maximum force (N) (5.0 [3.2-8.0] vs 3.8 [2.3-12.8]; p = 0.739) did not differ significantly between the groups. In the survey, 17/20 (85%) participants recommended to include robotic simulation training, 14/20 (70%) participants preferred to start with robotic simulation, and 20/20 (100%) to include suture-pad training. CONCLUSION: Surgical performance during robotic HJ in robotic novices was significantly better after robotic simulation-first training followed by suture-pad training. A robotic suturing curriculum including both robotic simulation and dry-lab suturing should ideally start with robotic simulation.

BACKGROUND: Per-oral plication of the (neo)esophagus (POPE) is an endoscopic procedure used to improve emptying of the defunctionalized esophagus or gastric conduit, with the hope of improving symptoms and quality of life. As this procedure has only been performed in the United States for the past 4 years, safety and efficacy have not been well established. METHODS: This is a retrospective case series for patients who underwent POPE from a single institution between 2019 and 2023. Data collected included demographics, preoperative diagnoses and treatments, imaging, endoscopic data, operative intervention, 90-day complications, and response to treatment. Quality of life and patient satisfaction data were collected by phone survey. RESULTS: Seventeen cases were identified, encompassing 13 primary procedures and 4 repeat POPEs (re-POPE). Eight patients had end-stage achalasia and 5 had impaired gastric emptying after esophagectomy with gastric conduits. Median age was 65 years and median ASA was 3, with 38.5% female patients. POPE was performed with 2-6 plication sutures in an average of 75 min. The majority of patients discharged home the same day. For the 17 procedures, there were 4 complications. Two patients required antibiotics for pneumonia, while 4 required procedural intervention. There were no deaths. Preoperative symptoms improved or resolved at initial follow up in 82.3% of patients. Four patients experienced symptom recurrence and required re-POPE, 1 with achalasia and 3 with gastric conduits. Although all achalasia patients had an "end-stage esophagus," none have required esophagectomy since the introduction of POPE. CONCLUSIONS: POPE is an endoscopic procedure that is efficacious in relieving emptying difficulties for the end-stage esophagus and gastric conduit. It may obviate the need for esophagectomy or conduit replacement. Also, it can be repeated in select patients. While the risk profile of complications is favorable compared to alternative operations, patients with gastric conduits are at higher risk.

CONTEXT: Health simulation is a recognized educational method for teaching and validating surgical procedural skills. The latter requires the development of adapted assessment tools, reaching different validity criteria. The aim of this study was to validate a multimodal assessment tool for a complex skin suturing exercise, combining a manual knot, an intradermal linear suturing and a needle holder tied knot. METHODOLOGY: The suturing exercise was realized on a synthetic skin model by voluntary participants after having obtained their written consent, including 9 postgraduate medical students, 40 surgical residents of different levels of experience, and a group of 9 senior surgeons. The multimodal assessment tool (MAT) combined a checklist, a speed score and a global rating scale. Each exercise was scored by two evaluators. Medical students' performances were filmed anonymously so that they could be scored iteratively. Content validity was tested through a satisfaction questionnaire randomly completed by participants. RESULTS: The MAT was considered relevant or very relevant by 98% of the participants, with a better appreciation for the checklist than for the global rating scale. Internal consistency was strong with a Cronbach α coefficient at 0.78, and a good correlation between the results of the checklist and the global rating scale (r=0.79, P<0.0001). The MAT showed continuous improvement in mean scores from 34.4±3.6 for novices to 47.4±2.5/50 points for experts, passing through three intermediate levels groups, and allowed for significant discrimination between groups. The MAT was reliable, with a coefficient of correlation set at 0.88 for intra-observer reliability, and 0.72 for inter-observer reliability. On sub score analysis, the global rating scale and the speed score better discriminated between groups than the checklist, the latter moreover showing slightly lower reliability than the global rating scale. CONCLUSION: Despite its banality in any surgeon's practice and the fact that it is taught from the 2nd cycle of medical studies, suturing and its technical components have rarely been the subject of publications dedicated to the validation of specific assessment tools. Hence, this work on the MAT and its sub scores made it possible to validate them on many validity and reliability criteria. They can therefore be proposed to surgical teachers for evaluating a complex suturing exercise, with a checklist that is easier to use even for novices and a global rating scale showing better discrimination capacity.

BACKGROUND: Porous high-density polyethylene (pHDPE) is an alternative material for a septal extension graft (SEG) in oriental rhinoplasty when autologous cartilage is limited. Although nasal packing (NP) and trans-septal suturing (TSS) techniques are routine procedures to obviate the dead space after septoplasty, they are associated with certain discomforts and complications. OBJECTIVE: To investigate the application of a submucosal trans-septal suturing (STSS) technique after SEG with pHDPE. METHODS: A prospective study was conducted on 60 female participants who underwent SEG with pHDPE. The participants were randomly divided into the NP group and STSS group. The extra surgical duration of NP and STSS, pain, nasal obstruction, and sleeping disturbance as well as postoperative complications were recorded and compared between groups. RESULTS: No significant difference was found between group NP and group STSS in terms of mean age. The mean extra surgical duration of group STSS was significantly longer than group NP. There were significant higher pains of group NP at 24 hours and 48 hours postoperatively, compared with group STSS. The NP group also experienced significantly more nasal obstruction and sleep disturbance within 48h postoperatively compared to the STSS group. There was one infection in each group, minor bleeding in two NP patients, and one STSS patient. There was no major bleeding, hematoma, graft exposure, or septal perforation in both groups. CONCLUSION: Although STSS needs a longer extra surgical duration than NP, it significantly improves the patient's postoperative comfort with a faster return to normal respiration compared to NP.
