Percutaneous transhepatic papillary balloon dilation combined with dual-frequency double-pulse laser lithotripsy for large-diameter common bile duct stones

Objective: To evaluate the safety and efficacy of percutaneous transhepatic papillary balloon dilation (PTPBD) combined with flexible ureteroscopy-guided dual-frequency double-pulse ND:YAG (FREDDY) laser lithotripsy (PTPBD-FREDDY) for the treatment of giant (>1.5 cm diameter) common bile duct stones. Methods: A retrospective analysis was conducted on 26 patients with large-diameter difficult choledocholithiasis admitted to two medical centers from December 2017 to October 2021. Among these patients, four could not tolerate surgery or endoscopic treatment, six experienced failure of endoscopic treatment, and 16 refused to undergo endoscopic or surgical treatment. All patients underwent the PTPBD-FREDDY procedure. The FREDDY laser lithotripsy was performed under ureteroscopic guidance, followed by a balloon to push the stones into the duodenum. The primary endpoint was the technical success rate, and the secondary endpoints included the rate of stone recurrence and related complications. Results: All 26 patients successfully completed the operation, achieving a technical success rate of 100%. The average lithotripsy frequency and operation time for bilirubin stones were significantly higher than those of mixed stones and cholesterol stones (P<0.01). The main postoperative complications included mild fever (n=3), abdominal pain (n=3), nausea (n=2) and vomiting (n=1). One patient experienced biliary tract bleeding, which improved after conservative treatment. No serious complications such as pancreatitis, sepsis, or biliary perforation were observed. After 2 years of follow-up, no cases of stone recurrence were observed. Conclusions: PTPBD-FREDDY is a safe and effective treatment for patients with giant common bile duct stones. It provides a new therapeutic option for patients with giant choledocholithiasis who can not tolerate surgery or have failed endoscopic treatment, demonstrating promising prospects.

Abstract IA053: Grateful strides toward spiritual well-being and exercise self-efficacy for Black breast cancer survivors

Abstract Background: Breast cancer (BC) survivorship care poses significant psychosocial and physical challenges, with survivors experiencing stress, inflammation, and poor lifestyle behaviors that impact their well-being and health-related quality of life. Black women with BC, who often experience higher rates of metabolic syndrome and related health complications, are particularly vulnerable. Black women with BC face unique health disparities, including a higher prevalence of metabolic syndrome, contributing to poorer prognoses. Spiritual well-being, particularly through practices such as gratitude journaling, has shown potential in improving psychological and physiological outcomes, but its effectiveness in Black BC survivors remains underexplored. Purpose: This pilot study aimed to assess the feasibility, acceptability, and preliminary efficacy of a gratitude journaling intervention tailored for Black BC survivors to enhance spiritual well-being, exercise self-efficacy, and mitigate inflammatory biomarkers. Methods: A two-group parallel random-assignment experimental design was used to compare a gratitude journaling intervention group with a general memory journaling control group over eight weeks. Twenty-six Black women with a history of BC in the community were enrolled and randomized. Surveys and biospecimen collections were conducted at baseline and post-intervention. Psychosocial measures included dispositional gratitude, spiritual well-being, perceived stress, Superwoman Schema dimensions, and exercise self-efficacy. Inflammatory biomarkers (TNF-α, IL-6, GDF15, CRP) were also measured. Results: Feasibility analysis indicated high recruitment (95%) and baseline assessment completion (100%), with 73% completing baseline and post-intervention assessments. Participants reported high satisfaction with the intervention. Significant improvement in spiritual well-being (p=0.014, ES=0.57) was observed in the intervention group, alongside large effect sizes in exercise self-efficacy (p=0.10, ES=0.391). Changes in dispositional gratitude, perceived stress, and Superwoman Schema dimensions were not statistically significant, although trends suggested positive impacts. Inflammatory biomarkers showed mixed results, with some indicating potential improvements but no significant differences overall. Discussion: The study highlighted the importance of culturally tailored interventions for Black BC survivors, demonstrating significant benefits in spiritual well-being and potential improvements in exercise self-efficacy. While changes in dispositional gratitude and perceived stress were not significant, the intervention group showed positive trends, suggesting potential benefits. Although the impact on inflammatory biomarkers was inconclusive, the study underscores the holistic approach of gratitude interventions in promoting overall well-being among Black BC survivors. Future research should focus on larger, randomized controlled trials to further elucidate the efficacy of gratitude-based interventions in this population.

Comparison of cost and complications of primary total hip arthroplasty versus oncologic proximal femur replacement

Aims and objectiveProximal femur replacement (PFR) is most commonly performed after a large resection of the proximal femur to remove tumor and is known to have high complication rates and worse function than a primary total hip replacement (THA). Many surgeons feel that current billing practices fail to adequately differentiate this procedure from a THA. This study aims to examine patients undergoing a primary THA or oncologic PFR and compare the relative economic impact and complication rates between cohorts. Materials & methodsPatient data was queried using a national database, identifying non-pediatric patients who underwent a primary THA or oncologic PFR. Exclusionary criteria were implemented, resulting in two cohorts, each with 380 patients matched in a 1:1 manner controlling for age, gender, and Charlson Comorbidity Index. Utilizing 2022 billing data, oncologic PFRs generated an average of 41.03 RVUs and primary THAs generated 19.60 RVUs. Total hospital cost was used to generate a cost:RVU ratio for each cohort. Key systemic and joint complication rates were additionally compared between cohorts. ResultsThe oncologic PFR cohort had significantly higher 90-day rates of anemia, deep vein thrombosis, and prosthetic dislocation compared to the primary THA cohort. The 90-day median hospital cost for oncologic PFR was $28,562.21 with a cost:RVU ratio of $696:1. The corresponding median hospital cost for primary THA was $9667.72, with a cost:RVU ratio of $493:1. ConclusionHospitals incur more cost per RVU for an oncologic PFR than a primary THA. Relative to primary THA, reimbursement for oncologic PFR is under-evaluated.

Safety of long-term esophageal stent use for multiple indications.

Long-term (>30 days) esophageal stenting is controversial. Previous studies have documented complications associated with long-term esophageal stent use. This study's objective was to investigate complications associated with long-term esophageal stent use. A retrospective review of stenting done by thoracic surgery for any reason between 2010-2020 was completed. Patients were included if they had at least 30 days of follow-up after their initial stent placement. Outcomes included stent dwell time, patient outcomes, procedural and stent-related complications. Fifty-six patients, with 25 having ≥2 stents placed were included; overall, 90 stents were placed. The median length of initial esophageal stent dwell time was 59 [interquartile range (IQR), 21-119] days. Stent migration was the most common complication and occurred more with benign indications (P=0.12). As the length of dwell time increased, prevalence of any complication decreased. Complication rates between short-term (<30 days) and long-term stents were not significantly different (P=0.39). No instances of esophageal perforation or aortoesophageal fistulas related to stents were identified. There was one instance of post-esophagectomy tracheoesophageal fistula which was managed successfully with prolonged stenting. Over a 10-year period, there were no instances of stent erosion into the aorta or esophageal perforation, and the most frequent stent-related complication was stent migration. Long-term esophageal stenting did not result in increased rates of stent related complications in our cohort. This case series demonstrates that long-term stents may be safely used for many different indications. Randomized controlled studies may be needed to validate these findings.

Endoscopic dacryocystorhinostomy with and without bicanalicular silicone tube in patients with a small lacrimal sac: a comparative study.

To establish whether bicanalicular silicone tube intubation is required during endoscopic dacryocystorhinostomy (En-DCR) for treating chronic dacryocystitis with a small lacrimal sac. In total, this study enrolled 264 patients diagnosed with unilateral chronic dacryocystitis with small lacrimal sacs via computed tomography-dacryocystography that underwent En-DCR from March 2016-September 2020. Patients were randomized into two treatment groups, with those in group A undergoing tubes intubation and those in group B not undergoing this procedure. The tubes were removed 3 months post-operation in group A. Surgical outcomes and related complication rates were then compared. This study included 242 patients, including124 and 118 in groups A and B, respectively. At the three-month follow-up time point, 12.90% of patients in group A exhibited ostial granulation tissue, with this frequency with no differences observed in group B (11.86%). At 6 months post-surgery, 80.65% of patients in group A and 72.88% of patients in group B exhibited successful surgical outcomes, with no significant differences between groups. At 9 months postoperatively, the overall effective success rate was 60.74%, and the success rate was significantlyhigher in group A relative to group B (group A: 75.81%; group B: 44.92%). There were no failed patient outcomes observed as of the 12-month follow-up time point. While En-DCR-based treatment of chronic dacryocystitis in those with smalllacrimal sacs did not yield satisfactory outcomes with respect to the overall effective success rate, these results suggest that intraoperative intubation may improve success rates in long-term follow-up.

Comparison between catheter ablation versus permanent pacemaker implantation as an initial treatment for tachycardia–bradycardia syndrome patients: a prospective, randomized trial

BackgroundClinical outcomes after catheter ablation (CA) or pacemaker (PM) implantation for the tachycardia–bradycardia syndrome (TBS) has not been evaluated adequately. We tried to compare the efficacy and safety outcomes of CA and PM implantation as an initial treatment option for TBS in paroxysmal atrial fibrillation (AF) patients.MethodsSixty-eight patients with paroxysmal AF and TBS (mean 63.7 years, 63.2% male) were randomized, and received CA (n = 35) or PM (n = 33) as initial treatments. The primary outcomes were unexpected emergency room visits or hospitalizations attributed to cardiovascular causes.ResultsIn the intention-to-treatment analysis, the rates of primary outcomes were not significantly different between the two groups at the 2-year follow-up (19.8% vs. 25.9%; hazard ratio (HR) 0.73, 95% confidence interval (CI) 0.25–2.20, P = 0.584), irrespective of whether the results were adjusted for age (HR 1.12, 95% CI 0.34–3.64, P = 0.852). The 2-year rate of recurrent AF was significantly lower in the CA group compared to the PM group (33.9% vs. 56.8%, P = 0.038). Four patients (11.4%) in the CA group finally received PMs after CA owing to recurrent syncope episodes. The rate of major or minor procedure related complications was not significantly different between the two groups.ConclusionCA had a similar efficacy and safety profile with that of PM and a higher sinus rhythm maintenance rate. CA could be considered as a preferable initial treatment option over PM implantation in patients with paroxysmal AF and TBS.Trial registrationKCT0000155.

A new type of dual-plane breast augmentation: Redefining parenchyma-muscle interface in high mobile glandular ptotic breast

BackgroundHigh mobile glandular ptotic breasts present the greatest challenge for implant breast augmentation with suboptimal outcomes occurring frequently. Here, we describe and evaluate an innovative approach for breast augmentation in this breast type. By widely disrupting and redefining the parenchyma-muscle interface, this technique offers opportunities to restore the takeoff point of the breast and improve the fullness of the upper pole, thus producing a “perkier” breast appearance. MethodsA retrospective review was performed, and 68 patients who underwent breast augmentation with either type III dual-plane or the new approach between January 2015 and January 2021 were included. The patients were divided into two groups. The aesthetic outcome and patient satisfaction were evaluated using different 10-point rating forms. Data on demographic information, surgical details, and relative complication rates were recorded and compared. ResultsUpon comparing the aesthetic outcomes and satisfaction, the test group demonstrated better breast shape, nipple-areola position, upper pole contour outcome, and upper pole satisfaction. No post-operative hematoma, seroma, or infection occurred in either groups. No double-bubble deformity occurred in the test group, whereas it occurred in two patients in the control group. The rates of capsular contracture were 1.4% and 1.6%, in the test and control groups, respectively. ConclusionsThe new approach is a safe surgical method with good aesthetic outcome, high patient satisfaction, and long-lasting result. This approach is a supplement to the dual-plane techniques, to realize the benefits of mastopexy and type III dual-plane breast augmentation.

Treatment of Noninfectious Uveitic Macular Edema with Periocular and Intraocular Corticosteroid Therapies: A Report by the American Academy of Ophthalmology

To review the evidence on the effectiveness and complications of periocular and intraocular corticosteroid therapies for noninfectious uveitic macular edema. A literature search of the PubMed database was conducted last in December 2021 and a post-assessment search was conducted in March 2023. The searches were limited to articles published in English and no date restrictions were imposed. The combined searches yielded 739 citations; 53 articles were selected for inclusion because the studies (1) evaluated periocular corticosteroid injection, intraocular corticosteroid injection or implant, suprachoroidal corticosteroid injection, or a combination thereof for uveitic macular edema; (2) had outcomes that included visual acuity (VA) or macular edema assessed clinically or imaged by OCT or fluorescein angiography; and (3) included more than 20 patients. This assessment reviewed 23 articles that provided level I or level II evidence from 18 studies on the use of periocular, suprachoroidal, and intravitreal triamcinolone acetonide injections and intravitreal dexamethasone and fluocinolone acetonide implants or inserts in noninfectious uveitic macular edema. These reports consistently demonstrated that all investigated periocular and intraocular corticosteroid therapies improved VA, macular structure, or both. One comparative study showed that intravitreal triamcinolone acetonide injection and the dexamethasone intravitreal implant had effectiveness superior to that of periocular triamcinolone acetonide injection for these outcomes. As a group, the studies highlighted the potential for these therapies to elevate intraocular pressure and to accelerate cataract formation. The published literature provides high-quality evidence that periocular and intraocular corticosteroid therapies are effective and safe for the treatment of noninfectious uveitic macular edema. However, information on the relative effectiveness and complication rates across the different therapies is limited. Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

(161) Is there a Difference in Inflatable Penile Prosthesis Mechanical Failure and Infections Rates in Relation to Prostate Cancer Treatment Modality (Radiation Therapy vs Radical Prostatectomy)

Abstract Introduction Inflatable Penile Prosthesis (IPP) implantation as a treatment for ED has high satisfaction rates in the general population; however, there is limited literature on quantification of complication rates as stratified by ED etiology. Objective Our aim was to compare mechanical failure and infection rates in patients undergoing IPP implantation for ED following Radical Prostatectomy (RP) versus radiation therapy (RT) for prostate cancer. Methods A retrospective chart review from our institutional database was conducted to identify 405 patients who underwent IPP placement at our institution from 2015–2019, then selecting for those whose etiology of ED was following RP or RT. To prevent crossover confounding; patients with history of pelvic radiation or salvage radiotherapy were excluded from the RP group and patients with history of RP were excluded from the RT group. Data was obtained from 75 patients who met criteria for inclusion: 44 patients in the RP group and 31 patients in the RT group. Mechanical failure, infection rates, mean EDITS scores and additional survey questions were compared between the radiation and RP groups. Results Patient demographic information and IPP complication and satisfaction rates are listed below in Table 1 and Figure 1. There was a statistically significant difference in number of patients experiencing IPP complications, 19.4% (n=6) of patients in the RT cohort and 4.5% (n=2) in the RP cohort, respectively. There was no statistically significant difference found in stratified complications- infection rates, device erosion rates, mechanical failure rates, or device removal and/or replacement rates between the two groups. The RP cohort had a significantly higher mean Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire score versus the RT cohort, 91.58 to 76.02, respectively. Conclusions These preliminary findings, while requiring large-scale follow up, suggest that there is a higher rate of IPP related complications in patients with device placement following RT for prostate cancer versus RP. Disclosure No.

Efficacy of Ethanol Sclerotherapy Versus Laparoscopic Excision in the Treatment of Ovarian Endometrioma.

The purpose of this study was to examine the recurrence rates of ovarian endometrioma, dysmenorrhea, dyspareunia, and related complications between sclerotherapy and laparoscopic ovarian cystectomy in individuals aged 25 to 38. Eighty-eight women participated in this retrospective, single-center study between January 2020 and February 2022. Patients received either laparoscopy or sclerotherapy, depending on the opinion of the pertinent physician. In this study, the following parameters were retrospectively analyzed in follow-up visits 2, 6 and 12months after sclerotherapy and laparoscopy: dysmenorrhea and dyspareunia by visual analog scale, complications following the intervention, and serial pelvic sonograms for endometrioma cyst recurrence. Moreover, serum Anti-Müllerian hormone (AMH) level before and 6months after sclerotherapy/surgery were analyzed. The collected data were then analyzed using R software. The results demonstrate the efficiency of both sclerotherapy and laparoscopic techniques in reducing endometrioma-related dysmenorrhea and dyspareunia over a 12-month period. There was no statistically significant difference in the occurrence of complications and recurrence rate between these two therapies, and both are equally beneficial. Also, the rate of AMH decline after laparoscopy was higher than sclerotherapy; however there was not a statistically significant change in serum level of AMH in laparoscopy compared to the sclerotherapy after 6months. Considering all the data, it appears that sclerotherapy, with its lower cost, shorter hospital stay, and quicker return to activities, can be a laparoscopic alternative to endometrioma cyst removal. More studies are required.

Clinical characteristics and outcome of tibial pilon fractures treated with open reduction and plating in a tertiary medical college

Introduction: Tibial pilon fracture possess a challenge to achieve optimum outcome because of soft tissue related complications and intra-articular nature of the fracture. Surgical treatments and outcomes vary in literature. The objective of this study was to assess the functional and radiological outcome of tibial pilon fractures treated with open reduction and internal fixation with plate and screws. Methods: This was a descriptive study of retrospective data of displaced tibial pilon fractures treated with open reduction and internal fixation with plate and screws. Functional outcome was assessed by American Orthopaedic Foot and Ankle Society (AOFAS) score and fracture union with plain radiography. Results: There were total of 20 cases of tibial pilon fractures with mean age of 41.4 years (SD±14.36). The mean AOFAS score was 81.60 (range 42-100) at mean follow up of 18.2 months (range 9-48). Good to excellent results was found in 12(60%) and fair results in 6(30%) cases. All the fractures united at mean of 5.8 months (range 5-7). Partial wound dehiscence was seen in 1(5%) case and marginal skin necrosis occurred in 3(15%) of the cases. Conclusions: Current study showed favorable radiological and functional outcome in most of the tibial pilon fractures treated with open reduction and internal fixation with plate and screws with acceptable rate of minor wound related complications

Trainees as primary operators do not significantly impact perioperative complication rates in breast surgery

BackgroundThere is a trend for specialist care in breast surgery resulting in fewer primary operative cases for general surgery trainees; and subsequently that trainees performing advanced oncoplastic techniques in breast surgery may negatively impact patient morbidity. We have reviewed the complication rates between Australian general surgery trainees and Breast Consultants. MethodsA retrospective analysis was performed over a 5-year period (January 2016–December 2021). The key endpoints measured were relative complication rates for consultants compared to trainees, subdivided by surgery type. Surgeries were categorised as either benign, primary breast cancer surgery or re-excision. ResultsA total of 2646 operative cases were performed with the primary operator rate for consultants 58.35 % (n = 1544) and for trainees 41.65 %% (n = 1102). The overall complication rate was 2.83 % (n = 75); the overall rate for the consultants was 2.65 % and 3.08 % for the trainees. The complication rates were not statistically significant (p = 0.59) between the two groups. The mastectomy only complication rate was higher in the consultant group with a result of 7.3 % compared to 2.8 % for the trainees however was not statistically significant (p = 0.18). The most common complication was haematoma formation for both groups. ConclusionsThis study has demonstrated that trainees can safely perform advanced oncoplastic techniques without statistically elevated morbidity. In an era where breast surgery caseloads are increasing, but the exposure to breast surgery during training are decreasing, it is necessary to implement a practice where trainees can perform breast operations under supervision at a specialized unit.

Orthotopic Heart Transplantation Followed By Autologous Stem Cell Transplantation in Patients with Cardiac AL Amyloidosis: Results from a Single Centre Prospective Study

Background: Patients with advanced cardiac AL amyloidosis have a dismal prognosis, with an overall survival (OS) of only 5 months for Stage IIIb patients (Palladini et al, 2023). Induction chemotherapy followed by high dose chemotherapy and autologous stem cell transplantation (HDT and ASCT) has been widely used as treatment for AL amyloidosis. However, patients with advanced cardiac AL amyloidosis are often not suitable for HDT and ASCT due to high transplant related mortality (TRM). Orthotopic cardiac transplantation (OHT) following induction treatment may improve patient fitness and thus allow HDT and ASCT to deepen and prolong responses. We present our single centre, prospective study of patients with Stage IIIa and Stage IIIb cardiac AL amyloidosis who received OHT followed by sequential HDT and ASCT. Aims: The primary outcomes were 3 year OS and progression-free survival (PFS). Efficacy and safety were assessed as secondary outcomes. Efficacy was evaluated by light chain and cardiac response after ASCT. Safety was assessed by rate of TRM, cardiac rejection, opportunistic infections, and cytopenia related complications. Methods: During 2015 to 2021, patients with Stage IIIa or Stage IIIb AL amyloidosis aged under 65 years underwent OHT followed by HDT and ASCT. Patients with multiple myeloma were excluded. At approximately 6 months following OHT, patients underwent stem cell mobilization with granulocyte colony-stimulating factor alone followed by peripheral blood apheresis stem cell collection. Mycophenolate immunosuppression was temporarily withheld during stem cell mobilization and collection. Patients then received a high dose melphalan ASCT followed by 3-6 monthly assessments. Results: Nine patients (median age of 53 years, range 47-60 years) completed both OHT and ASCT. Seven other patients were screened but did not proceed with OHT. The cohort included both stage IIIa (55%) and stage IIIb (44%) patients. Most patients received cyclophosphamide-bortezomib-dexamethasone induction therapy (89%) and one patient received lenalidomide-bortezomib-dexamethasone. The median time from diagnosis of AL amyloidosis to OHT was 11 months (range 5-57 months) and median time from OHT to ASCT was 7 months (range 5-8 months). 3 year OS was 83% and PFS was 56% (Figure 1). At a median follow up of 37 months (range 17-69 months), 89% of patients remain alive. One patient with Stage IIIa disease who underwent HDT and ASCT with progressive disease (PD) died 28 months following ASCT due to PD. Subgroup analysis demonstrated 3 year OS in Stage IIIa patients of 75% compared to 100% in Stage IIIb (p=0.48). 3 year PFS was 53% in Stage IIIa patients and 66% in Stage IIIb (p=0.8). Patients in complete remission (CR) prior to ASCT had an improved 3 year OS of 100% compared to 66% for those in partial remission (PR) or with PD (p=0.32). 3 year PFS was significantly improved at 100% when ASCT occurred in CR compared to 0% in those in PR or with PD (p=0.01) (Figure 2). All patients either maintained a CR or achieved an improved haematological response following HDT and ASCT, with 89% of patients in CR at 6 months post ASCT. At the median follow up of 37 months, 78% were in CR and 22% had PD. At last follow up, there has been no documented amyloid recurrence in a cardiac allograft. There was no TRM noted in this study. All patients had cardiac rejection with 66% developing Grade 3A/2R rejection requiring methylprednisone. The most common infective complication was CMV reactivation (44%). Other infective complications included cryptococcal infection (11%), aspergillus and MAC infection (11%) and HSV reactivation requiring hospitalization (11%). During admission for HDT and ASCT, 89% had febrile neutropenia and there were no bleeding complications. Conclusions: We have demonstrated, in a prospective design, that sequential OHT/ASCT following induction therapy is safe in patients with Stage IIIa/b cardiac AL amyloidosis without an increase in TRM. This approach was associated with excellent survival outcomes compared with historical cohorts. Given the deep and prolonged responses seen with daratumumab based induction, a risk adapted strategy may be more appropriate moving forward, with only those not achieving a haematological CR undergoing consolidation ASCT following OHT.

Comparison of the postoperative outcome with and without intraoperative leak testing for sleeve gastrectomy: a systematic review and meta-analysis of 469588 cases.

Postoperative staple line leakage (SLL) after sleeve gastrectomy (SG) is a rare but serious complication. Many surgeons routinely test anastomosis with an intraoperative leak test (IOLT) as part of the SG procedure. This meta-analysis aims to determine whether an IOLT plays a role in reducing the rate of postoperative staple line related complications in patients who underwent SG. The authors searched the PubMed, Web of science, the Cochrane Library, and Clinical Trials.gov databases for clinical studies assessing the application of IOLT in SG. The primary endpoint was the development of postoperative SLL. Secondary endpoints included the postoperative bleeding, 30 days mortality rates, and 30 days readmission rates. Six studies totaling 469588 patients met the inclusion criteria. Our review found that the SLL rate was 0.38% (1221/ 324264) in the IOLT group and 0.31% (453/ 145324) in the no intraoperative leak test (NIOLT) group. Postoperative SLL decreased in the NIOLT group compared with the IOLT group (OR=1.27; 95% CI: 1.14-1.42, P =0.000). Postoperative bleeding was fewer in the IOLT group than that in the NIOLT group (OR 0.79; 95% CI: 0.72-0.87, P =0.000). There was no significant difference between the IOLT group and the NIOLT group regarding 30 days mortality rates and 30 days readmission rates ( P >0.05). IOLT was correlated with an increase in SLL when included as a part of the SG procedure. However, IOLT was associated with a lower rate of postoperative bleeding. Thus, IOLT should be considered in SG in the situation of suspected postoperative bleeding.

Treatment of cerebrospinal fluid leakage with prolonged use of subfascial epidural drain and antibiotics in patients of thoracic myelopathy after posterior decompression surgery.

Cerebrospinal fluid leakage (CSFL) is a prevalent and vexing complication associated with spine surgery. No standard protocol is available guiding CSFL management, especially for thoracic CSFL. The aim of this study was to retrospectively evaluate the efficacy of prolonged use of subfascial epidural drain and antibiotics to treat CSFL after posterior thoracic decompression surgery. Fifty-six patients with an average age of 52.3 years (24-76 years), who underwent thoracic decompression with CSFL (group A) and 65 patients with an average age of 54.9 years (25-80 years) without CSFL (group B) were retrospectively reviewed. Patients in group A had prolonged use of subfascial drainage and antibiotics and patients in group B were treated with conventional methods. The surgical results and rate of wound related complications was compared between the two groups. The average subfascial drainage time was 7.0 ± 2.7 days (2-16 days) and 3.8 ± 1.4 days (2-7 days) in group A and B, respectively. Higher occupation rate (>49%), presence of dural ossification and higher MRI grade (>2) were more likely to presented with CSFL. In group A, four patients (7.1%) presented with deep wound infection and were successfully managed with wound debridement or intravenous antibiotics. In group B, one patient (1.5%) had a superficial wound infection and was treated with antibiotics. No patients presented with wound dehiscence, wound exudation or CSF fistulation. The occupation rate of ossified mass and presence of dural ossification were the major risk factors of CSFL. No significant difference in infection rates was observed between the patients in group A and B.

Comparison of Two Centers' Experience in Pediatric Supine and Prone Miniaturized Percutaneous Nephrolithotomy with Propensity Match Analysis.

Introduction: Percutaneous nephrolithotomy (PNL) is the treatment of choice in children with complex and large stones. With the experience gained from adult practice, supine PNL is increasingly performed in children as well. We aimed to evaluate the comparative results of prone and supine mini-PNL (m-PNL) performed for large/complex stones in children. Patients and Methods: The study included children who underwent supine and prone m-PNL at two centers between September 2019 and 2022. Patients were divided into two groups with a 1:1 ratio to index supine m-PNL and prone m-PNL cases for the size, number, location of the stones, degree of hydronephrosis, and age. Operative related parameters, success, and complication rates are being discussed on a procedure-based manner. Results: Forty-two patients (21 supine and 21 prone) were included. The mean age was 9.6 ± 4 years and mean stone size was 28.8 ± 13.6 mm. Regarding the operative data, the mean duration of procedure time was 65.7 ± 17.8 minutes in supine group, whereas 86.9 ± 19.0 minutes in prone group (p = 0.001). Fluoroscopy time was shorter in supine group (p = 0.027). Tubeless PNL was performed in 11 cases of prone group (52%), whereas this number was 18 (86.7%) in supine group (p = 0.019). Stone-free rates were similar in both groups (supine m-PNL: 90.5%, prone m-PNL: 85.7%, p = 0.634). Complications were minor in nature in most of the cases of both groups, which resolved with supportive measures in a short period of time. However, there was a statistically significant difference regarding the location and number accesses between two groups (p = 0.008). Simultaneous flexible ureterorenoscopy was performed in eight patients in the supine PNL group (<0.001). Conclusions: Our current findings and the highly limited data reported in the literature indicate that as an established minimal invasive treatment alternative m-PNL procedure in supine position can also be performed with similar success and complication rates in pediatric population.

Pulmonary artery aneurysm in pulmonary arterial hypertension associated with congenital heart disease

Abstract Introduction Pulmonary artery aneurysms are a common finding in patients with congenital heart disease, often asymptomatic and with a described low complication rate. The aim of this study is to assess the prevalence of PAA in a population with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD) and associated complications. Methods All adult patients with PAH-CHD at our institution with angiography of the pulmonary tree by computed tomography (CT) or magnetic resonance imaging (MRI) were included in a retrospective analysis. PAA was defined as a main PA diameter &amp;gt; 40 mm. Results In this study, the frequency of PAA was as high as 76%. Simple pre-tricuspid lesions had larger diameters than post-tricuspid lesions (p=0.004), but there were no significant differences with complex lesions. Also, no differences were found between the median diameters of the different PAH-CHD groups. No relationship was seen between the development of aneurysms or larger diameters and haemodynamic severity, even a majority of patients had severe pulmonary arterial hypertension. 15 patients (25% of total with PAA) had complications related to PAA: 4 patients with PA dissection (isolated or with associated thrombosis), 7 patients with chronic pulmonary thrombosis and 5 patients with left main coronary artery compression (figure 2). There were no complications in patients with diameters less than 40 mm. During a median follow-up of 3.8 years (IQR 1.6 to 6.4 years) 24 patients (30%) died or needed lung/cardiopulmonary transplantation (17 and 7 respectively). Only two (8.3%) of the patients with final events did not have PAA. Survival analysis (figure 1) showed a higher rate of death or need for transplantation in patients with pulmonary artery aneurysm, especially if there was an added complication (log-rank test, P=0.017). Conclusions Pulmonary artery aneurysms in patients with pulmonary arterial hypertension associated with congenital heart disease are common. The rate of related complications is also high in this population and may have prognostic implications.Survival analysisComplications related to PA

Rigid Plate Fixation for Closure of Emergent Sternotomies for Trauma.

No studies to date have evaluated the use of rigid plate fixation for emergent sternotomy in trauma patients. We evaluated our use of rigid plate fixation vs wire cerclage in patients requiring emergent sternotomy. We hypothesized there would be no difference in complications related to sternal closure between the two groups. We performed a retrospective cohort study to include all patients who underwent emergent sternotomy from 1/1/2018 to 1/31/2021 and survived to have their sternum closed. Outcomes in patients closed with wire cerclage group (WC) were compared to patients who underwent rigid plate fixation (RPF). Twenty-two patients underwent emergent sternotomy. There were 11 patients in each group. There was no significant difference in admission demographics, ISS, or admission characteristics between the two groups. Complication rates related to closure (wound infection and hardware removal) were not significantly different (WC 27% vs RPF 9%, P = .58). Neither hospital length of stay (WC: 29 days vs RPF: 13 days, P = .13), ICU length of stay (WC: 6 days vs RPF: 7 days, P = .62), nor the number of ventilator days (WC: 3 days vs RPF: 1 day, P .11) were statistically different. All patients survived to discharge. This is the first study comparing RPF and WC for sternotomy closure in the setting of trauma. We found no difference in the rate of wound related complications. This study demonstrates the feasibility of rigid plate fixation for trauma sternotomy closure and lays the foundation for future prospective studies.

Post-Operative Complications after Acute Achilles Tendon Rupture Repair: A Survival Analysis of Minimally Invasive vs Open Techniques

Category: Sports; Ankle Introduction/Purpose: Acute Achilles tendon ruptures (ATRs) can be treated surgically through either open repair or minimally invasive surgical techniques (MIS). While the relative complication rates between these techniques, including wound dehiscence, re-rupture, and sural nerve injury, have been debated, many studies demonstrate no significant difference between these two approaches. In this study, we conducted a Kaplan-Meier survival analysis to compare the incidence and timing of complications between open and MIS repair of acute ATRs and examine factors that may influence these rates. Methods: A retrospective study was conducted to evaluate the outcomes of patients (≥18 years) who underwent surgical intervention for acute ATR within a four-week period following injury, with a minimum follow-up of three months. Data on demographic variables, type of surgical procedure (MIS or open approach), and the occurrence and timing of postoperative complications were collected. Postoperative complications were classified as venous thromboembolism (VTE), re-rupture, surgical site infecti+D2on (SSI), wound dehiscence, and sural nerve injury.The Kaplan-Meier method was employed to compare the complication rates between the MIS and open repair groups. The log-rank test was used to test the equality of survivor functions. The Cox proportional hazards model was employed to determine predictors of complications. Results: In total, 417 patients were included in the final analysis. The MIS group had a higher proportion of patients with tobacco use. Fifty-two complications in 50 patients were recorded (Table 1). We found no significant difference in the complication rates between the MIS and open repair groups. However, Cox proportional hazards modeling revealed that body mass index (BMI) was a significant predictor of re-ruptures (HR 1.2, 95% CI = 1.05–1.4) and that surgical delay was found to be a significant predictor of wound dehiscence (HR 1.2, 95% CI =1.01–1.3) and sural nerve injury (HR 1.2, 95% CI =1.1–1.3). A surgical delay of more than 2 weeks was noted to have a positive likelihood ratio of 2.3 for wound dehiscence and 3.1 for sural nerve injury. Conclusion: The results of this study indicate that MIS and open repair techniques for acute ATRs demonstrate comparable complication rates. However, patients with elevated BMI exhibit an increased risk of re-rupture. Those with surgical delay beyond two weeks have an elevated likelihood of wound dehiscence and sural nerve injury, presumptively due to associated scaring and the requisite tissue manipulation. Surgeons and patients may consider these variables when formulating a surgical treatment plan.

Spinal cord injury after open and endovascular repair of descending thoracic aneurysm and thoracoabdominal aortic aneurysm: an updated systematic review and meta-analysis.

Spinal cord injury (SCI) is a rare but severe complication after open or endovascular repair of descending thoracic aneurysms (DTAs) or thoracoabdominal aortic aneurysms (TAAAs). This meta-analysis aims to provide a comprehensive assessment of SCI rates and factors associated with SCI. A systematic literature search was performed in September 2022 looking for studies on open and/or endovascular repair of DTA and/or TAAA published after 2018, to update the results of our previously published meta-analysis. The primary outcome was permanent SCI. Secondary outcomes were temporary SCI, 30-day and in-hospital mortality, follow-up mortality, postoperative stroke, and cerebrospinal fluid (CSF) drain-related complications. Data were pooled as proportions using inverse-variance weighting. A total of 239 studies (71 new studies and 168 from our previous meta-analysis) and 61,962 patients were included. The overall pooled rate of permanent SCI was 3.3% [95% confidence interval (CI), 2.9-3.8%]. Open repair was associated with a permanent SCI rate of 4.0% (95% CI, 3.3-4.8%), and endovascular repair was associated with a permanent SCI rate of 2.9% (95% CI, 2.4-3.5%). Permanent SCI was 2.0% (95% CI, 1.2-3.3%) after DTA repair, and 4.7% (95% CI, 3.9-5.6%) after TAAA repair; permanent SCI rate was 3.8% (95% CI, 2.9-5.0%) for Crawford extent I, 13.4% (95% CI, 9.0-19.5%) for extent II, 7.1% (95% CI, 5.7-8.9%) for extent III, 2.3% (95% CI, 1.6-3.5%) for extent IV, and 6.7% (95% CI, 1.7-23.1%) for extent V TAAA aneurysms. The pooled rate of CSF drain related complications was 1.9% (95% CI, 0.8-4.7%) for severe, 0.4% (95% CI, 0.0-4.0%) for moderate, and 1.8% (95% CI, 0.6-5.6%) for minor complications. Permanent SCI occurs after both endovascular and open DTA or TAAA repairs. Open repairs and TAAA repairs have higher risk of SCI compared with endovascular or DTA repairs. In particular, extent II aneurysms present the highest overall risk of SCI.
