Clinical-surgical Characteristics of Patients with Macular Hole. Exilaser Ophthalmological Center. Cuenca, Ecuador. 2015-2019

Background: The macular hole (MH) is one of the least studied ophthalmological pathologies; satisfactory treatment has been achieved through the implementation of surgical techniques a few years ago and the study and analysis of its clinical-surgical characteristics are of vital importance to assess the success of surgery with intrinsic and extrinsic factors. Objective: Describe the clinical-surgical characteristics of patients diagnosed with a macular hole at the EXILASER Ophthalmological Center in Cuenca in the period 2015-2019. Methods: Descriptive, retrospective study. The study universe corresponds to 75 patients who attended the EXILASER Ophthalmological Center and were diagnosed with MH between January-2015 and December-2019. Results: 76.0% of the patients are women; 81.3% are between 60 and 79 years old; 96.0% reside in urban areas; 34.7% are dedicated to housework; 24.0% report cataracts; 26.7% have arterial hypertension; 84.0% presented loss of central vision; 80.0% had decreased visual acuity. 50.7% presented affection only in the right eye; 53.3% had a chronic evolution greater than one year; 33.3% presented grade III MH. 44.0% had surgery; 93.9% had anatomical surgical closure. The relationship between the degree of MH, time of evolution, and closure of the MH was not significant (p> 0.05). Conclusion: The success rate of MH closure after surgical intervention is greater than 90% with improvement in postoperative visual acuity. No significant association was found between the grade of the MH, time of evolution, and the closure of the MH.

Comparison Between Flap and Primary Closures of Persistent Tracheocutaneous Fistula: A Scoping Review.

Objectives: To compare the susceptibility and complication rates between flap and primary closures for tracheocutaneous fistula (TCF). Methods: We searched 4 online databases (Web of Science, Cochrane Library, PubMed, and Scopus) for relevant articles published from study inception until August 2022. Studies including at least 5 adult or child patients with persistent TCFs who underwent closure surgery via primary or flap repair were included. All included studies reported outcomes of surgical repairs such as successful closure rates and complications. In addition, we performed single-arm meta-analyses for each surgical method using the Open Meta-Analyst software to calculate the pooled event rate with a 95% confidence interval (CI); compared the 2 surgical procedures using the Review Manager software using the risk ratio with 95% CI; and assessed study quality based on the National Heart, Lung, and Blood Institute criteria. Results: Overall, 27 studies with 997 patients were included. No significant difference was observed between the closure success and major complication rates of surgical methods. The primary and flap closures had overall success rates of 0.979 and 0.98, respectively. The overall major complication rates in primary and flap closures were 0.034 and 0.021, respectively; and that of minor were 0.045 and 0.04, respectively. In primary closure, a significant decrease in the success rate with increasing age at the time of decannulation was observed. In addition, the risk of major complications increased with increasing time from decannulation to closure. Conclusions: Both the primary and flap repairs of TCF are effective based on closure success and complication rates; therefore, they are both acceptable therapeutic alternatives, and flap repair can be considered when other techniques have failed. However, further prospective randomized studies comparing these 2 procedures are needed to support our results.

Effects of morphological characteristics of patent foramen ovale by transesophageal echocardiography on minimalist transcatheter closure in southern China.

Transcatheter closure has become one of the main treatment methods for patent foramen ovale (PFO). However, the population in southern China is generally thin and the size of PFO is small, so the application of minimalist surgery is challenging. This study aimed to analyze the morphological characteristics of PFOs in southern China by transesophageal echocardiography (TEE), and to explore the influence on minimalist transcatheter closure. About 110 patients with PFO closure in our hospital were selected. All cases were examined by TEE including the PFO size, length, septum secundum thickness, color characteristic and surrounding structures, and morphologically classified. During the operation, the procedure time, number of times for the guidewire attempting to pass the interatrial septum and the success rate of simply using J guidewire to cross the interatrial septum were recorded. About 110 cases of PFO were classified into two categories and four subtypes, including 55 cases with Uniform Channel Type (UCT, 50.0%), 16 cases with Irregular Channel Type (ICT, 14.6%), 15 cases with Right Funnel Type (RFT, 13.6%), and 24 cases with Left Funnel Type (LFT, 21.8%). According to the complexity of the procedure, they were divided into simple procedure (n=73) and complex procedure (n=37). Multivariate logistic regression showed that the anatomical types of PFO, the tunnel entrance size, and the tunnel entrance size <2mm were independent factors affecting the complexity of procedure [OR=2.819, 95% CI (1.124, 7.066), p=.027; OR=.027, 95% CI (.004, .208), p=.001; OR=4.715, 95% CI (1.028, 21.619), p=.046]. With ICT and LFT groups, the procedure duration was relatively long (p<.001), number of times for the guidewire attempting to pass the interatrial septum was significantly increased (p<.001), and the success rate of simply using J guidewire to cross the interatrial septum was relatively low (p<.001). The PFO size in southern China was relatively small and characterized by large tunnel tension. It was concluded that TEE could clearly show the morphological characteristics of PFO, which could provide guidance for making more reasonable surgical plans in clinical practice, shorten the procedure time and improve the success rate of PFO closure.

Outcome of Endoscopic Repair of Nasal Septal Perforation.

The anterior ethmoidal artery (AEA) flap has been demonstrated to be a reliable option for endoscopic repair of symptomatic nasal septal perforations. The purpose of this study is to study the outcome of this technique. A retrospective case series of all consecutive patients who underwent repair of nasal septal perforation utilizing the AEA flap among 2 institutions from August 2020 to July of 2022 was conducted. Demographics and comorbidities were collected preoperatively and postoperatively. The main outcome of this study was to identify the risk factors for surgical failure. Forty-one patients were included. Mean perforation size was 2.2 cm (range 0.5-4.5 cm). Mean age was 42.5 years (range 14-65 years), 53.6% were female, 39% were active smokers, mean body-mass-index (BMI) was 31.9 (range 19.1-45.5), 20% with history of CRS and 31.7% had diabetes mellitus (DM). Etiologies of the perforation included idiopathic (n = 12), iatrogenic (n = 13), intranasal drug use (n = 7), trauma (n = 6), and secondary to tumor resection (n = 3). Overall success rate for complete closure was 73.2%. Active smoking, history of intranasal drug use, and DM were significantly associated with surgical failure (72.7%vs 26.7%, P = .007; 36.4%vs 10%, P = .047; and 63.6%vs 20%, P = .008 respectively). The endoscopic AEA flap is a reliable technique for closure of nasal septal perforation. It may not work when the etiology is intranasal drug use. Close attention to diabetes and smoking status is also needed.

Tracheocutaneous Fistula After Tracheostomy: Spotlight on a Closure Technique With a High Success Rate.

Tracheostomy is a commonly performed procedure in patients requiring prolonged mechanical ventilation. While it effectively provides a secure airway, tracheostomy can lead to complications, such as tracheal stenosis, tracheomalacia granulation tissue, pneumonia, aspiration tracheovascular fistula, tracheoesophageal fistula, and tracheocutaneous fistula. In this systematic review, we aim to identify the most suitable closure method and compare recurrence outcomes between methods for persistent tracheocutaneous fistula (TCF) in all age groups. We conducted a bibliographic search between January 1st, 2011 and March 10th, 2021 in the PubMed, B-on, Scopus, and Web of Science databases, and also performed a manual search to identify relevant articles. Our inclusion criteria were case series or comparative studies of surgery for persistent TCF and the success rate of TCF closure in patients both below and above 18 years of age. After applying the inclusion criteria to the research results, we included nine studies in our analysis. We found that closure by secondary intention is the most effective method for TCF closure, followed by primary and secondary intention combined. The success rate with most of the techniques was high, regardless of the size of the fistula or associated comorbidities, and its simplicity makes it an appealing treatment option in the care of patients with TCF. In conclusion, this systematic review highlights the importance of selecting an appropriate closure method for persistent TCF and provides valuable insights into the success rate of various techniques.

Anatomical predictors for suture-based closure of the patent foramen ovale: A multicenter experience.

NobleStitch EL is a novel suture-based technique used for patent foramen ovale(PFO) closure and an alternative to traditional double-disc devices without the need for antithrombotic therapy. However, successful closure rates are still unknown, and certain anatomies may be unfavorable for successful closure. We assessed the efficacy of the NobleStitch EL and sought to identify patient-related anatomical features associated with successful suture-based closure. We included 55 patients who underwent PFO closure with the NobleStitch EL in The Netherlands and Switzerland. Successful closure was defined as residual right-to-left shunt grade ≤1 with Valsalva maneuver at a cardiac ultrasound. Predefined possible anatomical determinants for effective closure included PFO length, atrial septal aneurysm, PFO entry- and exit diameter. Successful closure was achieved in 33 patients (60%). The PFO length was shorter in patients with successful closure compared to unsuccessful closure with a median length of 9.6 mm (IQR 8.0-15.0) versus 13.3 mm (IQR 11.4-18.6) on preprocedural ultrasound (p = 0.041) and 9.9 mm (IQR 8.0-13.1) versus 12.5 mm (IQR 9.7-15.4) on angiography (p = 0.049). Additionally, the PFO exit diameter and PFO volume were smaller in patients with successful closure than unsuccessful closure, with a mean diameter of 7.0 ± 3.1 mm versus 9.5 ± 3.8 mm (p = 0.015) and a median volume of 381 mm3 (IQR 286-894) versus 985 mm3 (IQR 572-1550) (p = 0.016). In our study cohort, the successful PFO closure rate using NobleStitch EL was relatively low (60%). With this alternative procedure, patients with a small PFO driven by a short PFO tunnel length and small exit diameter seem to be eligible for successful suture-based closure.

Complex duodenal fistulae: a surgical nightmare

IntroductionA common feature of external duodenal fistulae is the devastating effect of the duodenal content rich in bile and pancreatic juice on nearby tissues with therapy-resistant local and systemic complications. This study analyzes the results of different management options with emphasis on successful fistula closure rates.MethodsA retrospective single academic center study of adult patients treated for complex duodenal fistulas over a 17-year period with descriptive and univariate analyses was performed.ResultsFifty patients were identified. First line treatment was surgical in 38 (76%) cases and consisted of resuture or resection with anastomosis combined with duodenal decompression and periduodenal drainage in 36 cases, rectus muscle patch, and surgical decompression with T-tube in one each. Fistula closure rate was 29/38 (76%). In 12 cases, the initial management was nonoperative with or without percutaneous drainage. The fistula was closed without surgery in 5/6 patients (1 patient died with persistent fistula). Among the remaining 6 patients eventually operated, fistula closure was achieved in 4 cases. There was no difference in successful fistula closure rates among initially operatively versus nonoperatively managed patients (29/38 vs. 9/12, p = 1.000). However, when considering eventually failed nonoperative management in 7/12 patients, there was a significant difference in the fistula closure rate (29/38 vs. 5/12, p = 0.036). The overall in-hospital mortality rate was 20/50 (40%).ConclusionsSurgical closure combined with duodenal decompression in complex duodenal leaks offers the best chance of successful outcome. In selected cases, nonoperative management can be tried, accepting that some patients may require surgery later.

A Single-Institutional Experience With Prenatal Diagnosis of Cloacal Exstrophy: Room for Improvement

IntroductionA single institutional study characterizes the rate of prenatal diagnosis of cloacal exstrophy (CE) and examines its role on successful primary closures. Materials and MethodsAn institutional database of 1485 exstrophy-epispadias patients was reviewed retrospectively for CE patients with confirmed presence/absence of prenatal diagnostics, primary exstrophy closure since 2000, institution of closure, and at least 1 year of follow up following closure. ResultsThe cohort included 56 domestic patients and 9 international patients. Overall, 78.6% (n = 44) of domestic patients were prenatally diagnosed while 21.4% (n = 12) were diagnosed postnatally. A positive trend was observed in the rate of prenatal diagnosis across the study period, 56.3%, 84.2%, 88.9% respectively (p = 0.025). Confirmatory fMRI was obtained in 40.9% (n = 18) of prenatally diagnosed cases. Patients diagnosed prenatally were found to be more likely to undergo treatment at exstrophy centers of excellence (72.1% v 33.3%, p = 0.020). Prenatal diagnosis was not predictive of increased rate of successful primary closure (75.6% vs 75.0%; p = 1.00; OR: 1.03, 95% CI: 0.23–4.58). Primary closures undertaken at exstrophy centers of excellence were significantly more likely to be successful compared to outside hospitals (90.9% v 50.0%, p = 0.002). ConclusionsThe rate of prenatal diagnosis of CE in patients referred for management to a high-volume exstrophy center is improving. Despite this improvement, patients continue to be missed in the prenatal period. While prenatal diagnosis offers the ideal opportunity to educate, counsel, and prepare expectant families, patients diagnosed at birth are not disadvantaged in their ability to receive a successful primary closure. Further research should investigate the benefit of patient referral to high-volume exstrophy centers of care to ensure optimal care and outcomes.

Do Propylene Glycol, Benzyl Alcohol, and Ethanol in Concomitant Drugs Influence Clinical Outcomes Following Intravenous Acetaminophen in Critically Ill Neonates?

Propylene glycol (PG) and benzyl alcohol (BA) have been shown to inhibit the metabolizing enzyme for acetaminophen in the liver. Ethanol has unpredictable effects on acetaminophen metabolism. Critically ill neonates commonly receive drug formulations containing PG, BA, and ethanol as excipients. Until now, there have been no reports on the influence of BA, PG, and ethanol as excipients in patients undergoing concomitant acetaminophen therapy. We devised the present study to evaluate whether any significant differences in plasma acetaminophen concentrations, liver function tests, and serum creatinine exist between neonates receiving excipients containing drugs compared to those without. We included neonates that were administered intravenous acetaminophen with at least one concomitant drug containing either BA, PG, or ethanol as excipients. Plasma acetaminophen concentrations and levels of liver function were evaluated using tests. The doubling of alanine aminotransferase levels was considered to be a marker of hepatotoxicity. Elevation of serum creatinine &gt;1.5 times higher than the baseline value was considered to be indicative of an acute kidney injury. Fifty-seven neonates were recruited in the study. No significant differences in the serum acetaminophen concentrations, liver and renal function tests, and rates of successful closure of ductus arteriosus were observed between the groups. No significant changes in the serum acetaminophen levels and the clinical outcomes were observed due to the presence of BA, PG, or ethanol in concomitant drugs as excipients. Probably, drugs containing these excipients can be safely administered, and even formulations containing these excipients with acetaminophen are likely to be safe for critically ill neonates.

Efficacy and Safety of Percutaneous Access Via Large-Bore Sheaths (22-26F Diameter) in Endovascular Therapy

Purpose: To evaluate the closure success rate’s outcomes with suture-mediated vascular closure device Perclose ProGlide in patients undergoing aortic or iliac artery endovascular repair using large delivery systems (>21F). Materials and Methods: We screened all the patient records in aortic databases at 2 centers who had undergone vascular interventions via ProGlide for percutaneous femoral access >21F between 2016 and 2020. Patients were divided into 2 groups according to the delivery system size: large (L) (22F–23F) and extra-large (XL) (24F–26F). Demographics, anatomical details, and outcome of percutaneous access were evaluated. Results: Included were 239 patients: 121 in the L group and 118 the XL group. Intraprocedural conversion to open surgery because of bleeding was necessary in 2% L and 6% XL patients (p=0.253). Severe femoral artery calcification was the sole risk factor for converting to open surgery (odds ratio=23.44, 95% confidence interval=1.49–368.17, p=0.025). In all, 2% of L and 3% of XL (p=0.631) did require late percutaneous intervention due to stenosis (all treated with balloon angioplasty). Overall, 3% developed pseudoaneurysm treated conservatively in all except one patient requiring surgical repair. Hematoma and groin infection were observed in 9% and 1%, respectively; none required surgical therapy. Conclusion: A femoral arterial defect after accessing the artery via a large bore sheath (22F–26F) can be closed successfully with ProGlide in more than 90% of patients. Severe femoral artery calcification is a risk factor for conversion to open surgery caused by bleeding. Clinical Impact This study adds evidence on efficacy of accessing the artery via a large bore sheath (22-26F) secured by ProGlide. In more than 200 patients conversion to open surgery was necessary in only 4%. Severe femoral artery calcification was the sole risk factor for converting to open surgery. Our findings encourage physicians to choose the percutaneous access even in patients requiring the use of large bore sheath.

Analysis of efficacy and safety of a new endoscopic anastomosis clip in the treatment of defects after endoscopic full-thickness resection

Objective: To investigate the efficacy and safety of a new endoscopic anastomosis clip in the treatment of defects after endoscopic full-thickness resection (EFTR). Methods: Retrospective cohort study. Fourteen patients [4 males and 10 females, aged (55.9±8.2) years (45-69 years)] with gastric submucosal tumors underwent EFTR at the First Affiliated Hospital of Soochow University were included from December 2018 to January 2021. Patients were divided into new anastomotic clamp group (n=6) and nylon ring combined with metal clips group (n=8). Preoperative endoscopic ultrasound examinations were required to all patients to evaluate the wound condition. The size of the defect, operation time required for wound closure, success rate of closure, postoperative gastric tube placement time, postoperative hospital stay, incidence of complications, preoperative and postoperative serological indexes were compared between the two groups. All patients were followed up after the operation, among which the general endoscopy was reviewed in the first month after the operation, and the telephone and questionnaire follow-up were used in the second, third, sixth month and one year after the operation to evaluate the therapeutic effect of the new endoscopic anastomosis clip and nylon rope combined with metal clip after the EFTR operation. Results: Both groups successfully completed EFTR and were successfully closed. There was no significant difference between the age, tumor diameter and defect diameter of the two groups (all P>0.05). Compared with the nylon ring combined with metal clip group, the operation time of the new anastomotic clip group was shortened [(5.0±1.8) minutes vs (35.6±10.2) minutes, P<0.001]. The operation time was shortened [(62.2±12.5) minutes vs (92.5±0.2) minutes, P=0.007]. Postoperative fasting time decreased [(2.8±0.8) days vs (4.9±1.1) days, P=0.002]. The hospital stay after operation was also shortened [(5.2±0.8) days vs (6.9±1.5) days, P=0.023]. The total intraoperative bleeding volume decreased [(20.00±5.48) ml vs (35.63±14.75) ml, P=0.031]. The patients in both groups received endoscopic examination 1 month after operation, and there was no delayed perforation and bleeding after operation. There was no obvious symptoms of discomfort. Conclusion: The new anastomotic clamp is suitable for the treatment of full-thickness gastric wall defects after EFTR, and shows advantages of shorter operation, less bleeding, and fewer postoperative complications.

Evaluation of the effect of a resorbable membrane on the closure of palatal fistulas.

A palatal fistula following the closure of palatal clefts remains a difficult clinical complication. Surgical treatment of fistulas is often complicated, with high recurrence rates. We present our results of fistula closure augmented with GTR, a resorbable membrane designed to promote guided tissue regeneration. We reviewed the records of 75 patients operated on between 2008 and 2022 for closure of the palatal fistula. The patients included 24 who underwent fistula closure augmented with GTR and 51 who underwent fistula closure with other techniques. We reviewed the age at surgery, sex, fistula location, and outcome. Operation success was defined as an asymptomatic patient with a healed fistula on clinical examination. The overall fistula closure rate was 79.1% in the GTR group and 76.5% in the non-GTR group(p = 0.79). The success rate of fistula closure in the GTR group is comparable to that in the non-GTR group in this study. An additional advantage is that this procedure does not require harvesting any autologous tissue and reduces tissue damage in the long term.

Twin-grasper assisted mucosal inverted closure achieves complete healing of large perforations after gastric endoscopic full-thickness resection.

This study aimed to demonstrate the feasibility and safety of a novel twin-grasper assisted mucosal inverted closure (TAMIC) technique for large perforations after gastricendoscopic full-thickness resection (EFTR) in a porcine model. Iatrogenic large perforations of the stomach were created and closed by an experienced endoscopist using the TAMIC technique in 12 pigs. Repeat gastroscopy was performed in 4 weeks after surgery to examine the wound sites and then the animals were killed. The primary outcomes were the successful TAMIC closure rate and the complete healing rate. Secondary end points included procedure time of TAMIC, complete inverted healing rate, delayed bleeding rate, and postsurgery perforation. Histologies of the wounds were analyzed by hematoxylin-eosin, Masson trichrome, and immunohistochemistry staining. The median size of the defects was 3.5 (range 2.5-4.5) cm. TAMIC was successfully performed in all the 12 pigs. Complete healing was achieved in 11 pigs 4 weeks after operation as one pig died postsurgery due to severe pneumonia. The median procedure time for TAMIC was 39 (range 23-81) min. The complete inverted healing rate was 45.5% (5/11). No delayed bleeding or postsurgery perforation was observed. Histologic analyses showed that both the epithelium and muscularis mucosae layers were appropriately connected under inverted healing. Twin-grasper assisted mucosal inverted closure is feasible and safe for closure of large perforations after gastric EFTR and could be a propagable and promising technique for clinical practice.

Macular buckling alone versus combined inverted ILM flap on macular hole-associated macular detachment in patients with high myopia.

To compare the efficacy of macular buckling (MB) alone against a combined internal limiting membrane (ILM) inversion flap for full-thickness macular hole (FTMH)-associated macular detachment (MD) in patients with high myopia. This was a prospective interventional case series of patients with high myopia surgically treated with MB alone or combined with an inverted ILM flap for FTMH- associated MD. Best-corrected visual acuity (BCVA) at the 24-month postoperative follow-up, rate of initial retinal reattachment and macular hole closure were measured. A total of 62 eyes from 62 participants (33 in the MB group, 29 in the combination group) were studied. Postoperative BCVA improved significantly in both the combination group (P < 0.001) and the MB group (P = 0.027). The postoperative BCVA at 12 months (P = 0.021) and 24 months (P = 0.041) was significantly better in the combination group than in the MB group. The postoperative BCVA was not significantly different between the eyes with closed and unclosed MH at each follow-up time point (P > 0.05). In the combination group, we observed earlier retinal reattachment and closure of the MH as well as a higher rate of MH closure (82.8% vs. 66.7%) than in the MB group, although this difference was insignificant (P = 0.248). MB combined with the ILM flap inversion technique achieved better postoperative BCVA and a higher success rate of MH closure than MB alone. We believe that combination surgery should be preferentially recommended.

P272 Reduced delay in diagnosis of Crohn’s disease in patients presenting with perianal disease: results of a retrospective cohort study at a non-academic, IBD-expert centre in the Netherlands

Abstract Background In up to 10% of patients with Crohn’s disease (CD), a perianal fistula (PAF) or perianal abscess (PAA) is the first presenting symptom. Delay in diagnosis in those patients is common and twice as long as in the general CD population. For the majority of patients (&amp;gt;70%) diagnosis takes &amp;gt;12 months. Delay is associated with more complex fistula formation impairing opportunities for clinical and radiological fistula closure, currently only successful in 65% and 30% respectively (combining anti-TNF and surgery). Moreover, delay in diagnosis is associated with worse outcomes and impaired quality of life (QoL). Since 2017, a low threshold for diagnostic work-up (ileocolonoscopy) for CD in patients presenting with perianal disease was introduced by a dedicated IBD surgeon in order to reduce delay in diagnosis of CD. Methods Patient records of all consecutive patients ≥16 years presenting with perianal disease (before diagnosis of CD) were retrospectively assessed. Differences in delay of diagnosis, defined as the time between first presentation with a PAA/PAF and confirmed diagnosis of CD, and differences in outcome measurements between the period 2007-2016 and 2017-2021 were determined in those eventually diagnosed with CD. Results A total of 25 patients were included in this study (n=13 in 2007-2016 and n=12 in 2017-2021, 52% male) with median age at presentation of 27 years (IQR 21,5-38,5). In the period 2007-2016, a median delay of 33 months (IQR 23-64) in CD diagnosis was observed and less than 20% of patients were diagnosed within one year after the first perianal surgical procedure. In the period 2017-2021 the median time to diagnosis significantly decreased to only 3 months (IQR 0-5, p=,000) and the proportion of patients diagnosed within one year increased drastically up to 79% (p=,000). Due to the relatively limited number of patients, no significant differences in outcome measurements (e.g. (re)interventions before CD diagnosis, number of successful fistula closure rates (clinical/radiological), and stomas/proctectomies) could be demonstrated between the two periods. Conclusion This study showed a significantly reduced delay in diagnosis of CD in patients presenting with perianal disease by introducing a low threshold for diagnostic work-up for CD. The promising results of this study were reason to continue data collection in a larger prospective study (currently ongoing) that forms the basis for the international development of an evidence based clinical decision tool including a perianal Red Flag Index and calprotectin measurement to select those at risk of having CD. Reducing delay in diagnosis by using such a clinical decision tool may improve outcomes and QoL in patients with perianal Crohn de novo.

Endoscopic Vacuum Therapy (EVT) versus Self-Expandable Metal Stent (SEMS) for Anastomotic Leaks after Upper Gastrointestinal Surgery: Systematic Review and Meta-Analysis.

Endoscopic treatment of post-esophagectomy/gastrectomy anastomotic dehiscence includes Self-Expandable Metal Stents (SEMS), which have represented the "gold standard" for many years, and Endoscopic Vacuum Therapy (EVT), which was recently introduced, showing promising results. The aim of the study was to compare outcomes of SEMS and EVT in the treatment of post-esophagectomy/gastrectomy anastomotic leaks, focusing on oncologic surgery. A systematic search was performed on Pubmed and Embase, identifying studies comparing EVT versus SEMS for the treatment of leaks after upper gastro-intestinal surgery for malignant or benign pathologies. The primary outcome was the rate of successful leak closure. A meta-analysis was conducted, performing an a priori-defined subgroup analysis for the oncologic surgery group. Eight retrospective studies with 357 patients were eligible. Overall, the EVT group showed a higher success rate (odd ratio [OR] 2.58, 95% CI 1.43-4.66), a lower number of devices (pooled mean difference [pmd] 4.90, 95% CI 3.08-6.71), shorter treatment duration (pmd -9.18, 95% CI -17.05--1.32), lower short-term complication (OR 0.35, 95% CI 0.18-0.71) and mortality rates (OR 0.47, 95% CI 0.24-0.92) compared to stenting. In the oncologic surgery subgroup analysis, no differences in the success rate were found (OR 1.59, 95% CI 0.74-3.40, I2 = 0%). Overall, EVT has been revealed to be more effective and less burdened by complications compared to stenting. In the oncologic surgery subgroup analysis, efficacy rates were similar between the two groups. Further prospective data need to define a unique management algorithm for anastomotic leaks.

Study On The Outcome Of Endoscopic Tympanoplasty Versus The Conventional Method.

BACKGROUND : Endoscopic tympanoplasty is an minimally invasive surgery for the repair of tympanic membrane with complete graft survival and hearing outcomes to the conventional microscopic surgery. This study was aimed to evaluate the success rate of endoscopic trans-canal closure of tympanic membrane perforation compared to the conventional post auricular approach using temporalis fascia and tragal cartilage as a graft. METHODS: Our study consisted of 50 patientswith chronic otitis media,with dry ear for last 2 months and all patients were between 18-50yrs of age.All selected patients were subjected to pre operative oto endoscopicand audiological assessment and underwent endoscopic trans canal tympanoplasty using temporalis fascia in some and tragal cartilage in some. RESULTS: Trans canal endoscopic surgery resulted in the successful healing of 97% whereas in conventional method successful healing was only up-to 92%. The average hearing gain was also significantly improved in endoscopic surgery compared to that of conventional method. When the operative time was considered the mean time in endoscopic method was lesser. All patients were followed up for a period of 3 months. CONCLUSION: Comparisons between these 2 groups focused on the surgical outcomes and restoration of hearing, including the duration of surgery. All patients were followed up for a period of 3 months. Using this method not only improves the cosmetic outcome but also reduces the post operative morbidity with shorter operative time.

Outcomes and Determinant Factors of Percutaneous Transcatheter Occlusion among Children with Patent Ductus Arteriosus in the East Coast Malaysia: A 10 Year Experience

Introduction: Transcatheter closure was a well-established procedure in patent ductus arteriosus (PDA). The aim of the study was to determine the outcomes, median time and PDAs closure from diagnosis and the predictive factors which influenced the decision for PDA closure. Material and methods: A 10-year retrospective record review was performed involving patients who had undergone transcatheter closure of PDA from January 2007 to January 2017 at a single centre in the North-eastern of Peninsular Malaysia. Descriptive statistics were used to examine all variables. Kaplan-Meier survival analysis was applied to determine median time for diagnosis and transcatheter closure of PDA. Multiple Cox regression analysis was used to identify predictors for early intervention of PDA closure. Results: A total of 123 patients were recruited with 65.9% of them were predominantly female. The age at the time of diagnosis was between 4-day to 14.5-year-old and median age for undergoing the procedure was 2.6-year-old (range:3-month to 15.8-year-old). The PDA size ranged between 0.2-12mm with 59% of the patients had large size PDA. Successful closure rate was achieved in 96.2 % with 3.8 % having very minimal residual shunt at 2 years post procedure. Complications were noted in 17 patients (4.0% major, 9.8% minor). Overall, the median time to diagnose and to close PDA were 6 months and 16.9 months respectively. Earlier intervention was likely to be performed in younger children (p&lt;0.001) with weight of less than 10 kg (p&lt;0.001). Conclusions: Transcatheter device closure was safe and effective in children with PDA with excellent outcome and minimal complication. Age and weight were the determinant factors for early PDA closure.

Reopenable clip-over-the-line method for closing large mucosal defects following gastric endoscopic submucosal dissection: Prospective feasibility study.

Large mucosal defects following gastric endoscopic submucosal dissection (ESD) cause postoperative bleeding. To address this limitation and ensure closure of large mucosal defects, we developed the reopenable clip-over-the-line method (ROLM) using a reopenable clip and nylon line. The purpose of this study was to evaluate the feasibility of the ROLM for closure of large mucosal defects following gastric ESD in a prospective, consecutive series of cases. We performed the ROLM on 50 consecutive patients with gastric mucosal defects at the Ise Red Cross Hospital and Mie Prefectural Shima Hospital. The time to complete the ROLM, numbers of clips and lines required, size of defect, and closure success rate were measured, and postoperative adverse events were recorded. In all, 50 lesions were included in this study period between July 2021 and March 2022. The success rates of defect closure and defect closure without submucosal dead space of the ROLM were both 100% (50/50), with a median ROLM time of 30 (range, 14-35) min and a median resected specimen major axis of 45 (range, 31-73) mm. The median number of reopenable clips used was 31 (range, 10-93). Following gastric ESD, two cases of post-ESD bleeding were observed during the follow-up periods. Our results suggest that ROLM is a feasible strategy for complete closure of mucosal defects post-ESD without submucosal dead space. Future comparative studies with post-ESD bleeding rate as the main outcome are desirable to evaluate the efficacy of ROLM.

Effectiveness and safety of endoscopic resection for duodenal gastrointestinal stromal tumors: A single center analysis.

Endoscopic resection for duodenal gastrointestinal stromal tumors (GISTs) is still considered a great challenge with a high risk of complications, including perforation, bleeding, tumor rupture, and residual tumor. To assess the effectiveness and safety of endoscopic resection for duodenal GISTs. Between January 2010 and January 2022, 11 patients with duodenal GISTs were treated with endoscopic resection. Data were extracted for the incidence of complete resection, bleeding, perforation, postoperative infection, recurrence, and distant metastasis. The incidence of successful complete resection of duodenal GISTs was 100%. Three cases (27.3%) had suspected positive margins, and the other 8 cases (72.7%) had negative vertical and horizontal margins. Perforation occurred in all 11 patients. The success rate of perforation closure was 100%, while 1 patient (9.1%) had suspected delayed perforation. All bleeding during the procedure was managed by endoscopic methods. One case (9.1%) had delayed bleeding. Postoperative infection occurred in 6 patients (54.5%), including 1 who developed septic shock and 1 who developed a right iliac fossa abscess. All 11 patients recovered and were discharged. The mean hospital stay was 15.3 d. During the follow-up period (14-80 mo), duodenal stenosis occurred in 1 case (9.1%), and no local recurrence or distant metastasis were detected. Endoscopic resection for duodenal GISTs appears to be an effective and safe minimally invasive treatment when performed by an experienced endoscopist.
