Mid-term outcomes after reverse total shoulder arthroplasty with latissimus dorsi transfer.

Reverse total shoulder arthroplasty is a common treatment for patients with rotator cuff arthropathy who have failed a prior rotator cuff repair. Latissimus dorsi transfer can be performed simultaneously to reverse total shoulder arthroplasty for patients with preoperative external rotation deficiency. Current literature is limited with several studies providing functional and pain improvements at short-term follow-up; however, there is a deficit in data regarding mid-term outcomes. The purpose of this study was to evaluate the clinical and radiographic outcomes following reverse total shoulder arthroplasty with latissimus dorsi transfer with mid-term follow-up. We hypothesized significant improvement in external rotation and shoulder functionality for patients with preoperative external rotation lag. We retrospectively reviewed patients who underwent reverse total shoulder arthroplasty with latissimus dorsi transfer. Preoperative and postoperative changes in range of motion were assessed. American Shoulder and Elbow Surgeon Score and the Simple Shoulder Test were used to evaluate changes in shoulder function while pain scores were assessed using the Visual Analog Scale (VAS). Radiographs were reviewed for rotator cuff arthropathy, fatty infiltration, scapular notching, baseplate loosening, and osteolysis. We reported frequency and mean ± standard deviation for categorical and continuous variables, respectively. Means were compared using the paired Student's t-test and proportions using the Chi-square test. Fifteen patients met the inclusion criteria. The mean age of the cohort was 71.7 ± 8.4 years (range 51.2-87.8 years) with a mean follow-up of 6.3 ± 4.1 years (range 1.0-14.5 years). Reverse total shoulder arthroplasty with latissimus dorsi transfer improved external rotation (-7 ± 21.3° to 38 ± 15.8°; p value = 0.001). There was no statistically significant difference regarding forward flexion (116.3 ± 45.4° to 133.7 ± 14.7°; p value = 0.17) and internal rotation (T12 to L2; p value = 0.57). The procedure led to an increase in American Shoulder and Elbow Surgeon Score scores (37 ± 19 to 62 ± 22; p = 0.005) and Simple Shoulder Test scores (2 ± 2 to 6 ± 3; p value = 0.001) with a significant reduction in Visual Analog Scale scores (5 ± 3 to 2 ± 3; p value = 0.022). The procedure corrected external rotation lag in 10 patients. Radiographically, rotator cuff arthropathy was found to be grade 3 in two patients, grade 4 A in four patients, grade 4B in eight patients, and grade 5 in one patient. On postoperative imaging, scapular notching was found in six patients (40%). Twelve patients had cortical humeral erosion at the site of the latissimus dorsi transfer. Only one patient experienced a shoulder-related complication which was aseptic baseplate loosening and required a revision reverse total shoulder arthroplasty with allograft. In this study, patients undergoing reverse total shoulder arthroplasty with latissimus dorsi transfer experienced improvements in range of motion, functional scores, and pain at mid-term follow-up. The shoulder-related complication rate was low.Level of evidence: IV; Case series.

Cardiac transplantation in adult congenital heart disease with prior sternotomy.

Adult congenital heart disease (ACHD) patients who require orthotopic heart transplantation are surgically complex due to anatomical abnormalities and multiple prior surgeries. In this study, we investigated these patients' outcomes using our institutional database. ACHD patients who had prior intracardiac repair and subsequent heart transplant were included (2008-2018). Adult patients without ACHD were extracted as a control. A comparison of patients with functional single ventricular (SV) and biventricular (BV) hearts was performed. There were 9 SV and 24 BV patients. The SV group had higher central venous pressure/pulmonary capillary wedge pressure (P=.028), hemoglobin concentration (P=.010), alkaline phosphatase (P=.022), and were more likely to have liver congestion (P=.006). Major complications included infection in 16 (48.5%), temporary dialysis in 12 (36.4%), and graft dysfunction requiring perioperative mechanical support in 7 (21.2%). Overall in-hospital mortality was 15.2%. Kaplan-Meier analysis showed a higher, but not statistically significant, survival after 10years between the ACHD and control groups (ACHD 84.9% vs. control 67.5%, P=.429). There was no significant difference in 10-year survival between SV and BV groups (78% vs. 88%, P=.467). Complex ACHD cardiac transplant recipients have a high incidence of early morbidities after transplantation. However, long-term outcomes were acceptable.

Wide QRS complex tachycardia after surgical repair of an isolated atrial septal defect: What is the mechanism?

Macroreentrant atrial tachycardia within the right atrium is the dominant mechanism in patients with prior surgical repair of atrial septal defects, with dual-loop circuits much more common than single-loop circuits. This case highlights the importance of clinical history for predicting arrhythmia mechanisms. Considering prior cardiac surgery may assist in preprocedural preparations and discussions regarding potential risks and benefits of catheter ablation.

False Lumen Stent-Grafts for Repair of Postdissection Aortic Aneurysms

PurposeTo evaluate the safety and efficacy of false lumen (FL) stent-grafts in the treatment of postdissection aortic aneurysms. Materials and MethodsEleven patients who underwent endovascular repair using FL stent-grafts from January 2016 to June 2019 were included. Among them, 2 patients had a prior history of type A aortic dissection, whereas 9 had undergone a prior endovascular repair for type B aortic dissection. Computed tomography angiography was performed to evaluate the reintervention and technical success rate, aortic remodeling, and other related aortic complications. ResultsThe mean age of patients was 55.6 ± 10.4 years. Technical success was achieved in all patients, and neither early mortality nor paralysis occurred. In total, 8 visceral branch arteries originating from the FL were reconstructed. The true lumen areas at the celiac axis, superior mesenteric artery, renal artery, and abdominal aortic bifurcation were significantly increased from 230.1 mm2 to 312.3 mm2, 212.1 mm2 to 277.5 mm2, 209.1 mm2 to 291.6 mm2, and 214.4 mm2 to 300.6 mm2, respectively (P < .05). The total diameter of the aorta at the 4 designated levels was stable or had shrunk in all patients. At a mean follow-up of 18.9 ± 7.6 months, 1 patient received re-intervention owing to iliac stent-graft occlusion. No aortic-related mortality occurred. ConclusionsFL stent-grafts can safely and effectively treat patients with postdissection aortic aneurysms. This strategy can be used to promote thrombosis of the FL and aortic remodeling. A larger sample and an extended follow-up period are needed to produce more conclusive results.

SAMHD1 restrains aberrant nucleotide insertions at repair junctions generated by DNA end joining.

Aberrant end joining of DNA double strand breaks leads to chromosomal rearrangements and to insertion of nuclear or mitochondrial DNA into breakpoints, which is commonly observed in cancer cells and constitutes a major threat to genome integrity. However, the mechanisms that are causative for these insertions are largely unknown. By monitoring end joining of different linear DNA substrates introduced into HEK293 cells, as well as by examining end joining of CRISPR/Cas9 induced DNA breaks in HEK293 and HeLa cells, we provide evidence that the dNTPase activity of SAMHD1 impedes aberrant DNA resynthesis at DNA breaks during DNA end joining. Hence, SAMHD1 expression or low intracellular dNTP levels lead to shorter repair joints and impede insertion of distant DNA regions prior end repair. Our results reveal a novel role for SAMHD1 in DNA end joining and provide new insights into how loss of SAMHD1 may contribute to genome instability and cancer development.

Lateral Axillary Exposure for Antegrade Access during Endovascular Repair of Complex Abdominal Aortic and Thoracoabdominal Aneurysms

During endovascular treatment of pararenal aortic aneurysms (PAA) and thoracoabdominal aortic aneurysms (TAAA), our antegrade vascular access of choice is a lateral axillary exposure (LAE). We directly access the axillary artery with multiple sheaths followed by primary closure of the axillary artery at case completion. The aim of this study is to describe our technique and to report our results with this approach. This study is a single-institution, retrospective review of 53 patients who were treated with parallel grafts for endovascular repair of PAA and TAAA from 2006 to 2018. The aortic repairs requiring LAE included: 9 cases of endo-leaks from prior endovascular repair, 20 TAAAs, and 24 PAAs. The axillary artery was exposed with a vertical axillary skin incision followed by retraction of the lateral border of the pectoralis major to expose the axillary artery distal to the pectoralis minor. A 5-French (F) through 12F sheaths were used to directly access the axillary artery for delivery of endovascular devices. Two hundred and sixty reno-visceral stents were delivered through 125 axillary sheaths in an antegrade fashion to 114 arteries without intraoperative complications or technical failures. Two postoperative complications included an access-site hematoma managed conservatively (1.9%) and a left brachial vein thrombosis treated with anticoagulation (1.9%). There were no cases of cerebrovascular or peripheral neurologic events, upper extremity ischemia, or reoperation related to LAE. LAE is a valid approach for upper extremity access during the endovascular repair of complex aortic aneurysms requiring simultaneous delivery of multiple reno-visceral devices. It does not require the use of a prosthetic conduit. There were no neurologic events or upper extremity ischemia in our series.

Biologic Mesh in Surgery: A Comprehensive Review and Meta-Analysis of Selected Outcomes in 51 Studies and 6079 Patients.

In recent decades, biologic mesh (BM) has become an important adjunct to surgical practice. Recent evidence-based clinical applications of BM include but are not limited to: reconstruction of abdominal wall defects; breast reconstruction; face, head and neck surgery; periodontal surgery; other hernia repairs (diaphragmatic, hiatal/paraesophageal, inguinal and perineal); hand surgery; and shoulder arthroplasty. Prior systematic reviews of BM in complex abdominal wall hernia repair had several shortcomings that our comprehensive review seeks to address, including exclusion of laparoscopic repair, assessment of risk of bias, use of an acceptable meta-analytic method and review of risk factors identified in multivariable regression analyses. We sought articles of BM for open ventral hernia repair reporting on early complications, late complications or recurrences and included minimum of 50. We used the quality in prognostic studies risk of bias assessment tool. Random effects meta-analysis was applied. This comprehensive review selected 62 articles from 51 studies that included 6,079 patients. Meta-analytic pooling found that early complications are present in about 50%, surgical site occurrences (SSOs) in 37%, surgical site infections (SSIs) in 18%, reoperation in 7%, readmission in 20% and mortality in 3%. Meta-analytic estimates of late outcomes included overall complications (42%), SSOs (40%) and SSIs (22%). Specific SSOs included seroma (14%), hematoma (4%), abscess (10%), necrosis (5%), dehiscence (8%) and fistula formation (5%). Reoperation occurred in about 17%, mesh explantation in 9% and recurrence in 36%. Estimates of nearly all outcomes from individual studies were highly heterogeneous and sensitivity analyses and meta-regressions generally failed to explain this heterogeneity. Recurrence is the only outcome for which there are consistent findings for risk factors. Bridge placement of BM is associated with higher risk of recurrence. Prior hernia repair, history of reintervention and history of mesh removal were also risk factors for increased recurrence.

Volar Plating versus Headless Compression Screw Fixation of Scaphoid Nonunions: A Meta-analysis of Outcomes.

Background Headless compression screw fixation with bone grafting has been the mainstay of treatment for scaphoid nonunion for the past several decades. Recently, locked volar plate fixation has gained popularity as a technique for scaphoid fixation, especially for recalcitrant or secondary nonunions. Purpose The purpose of this meta-analysis was to compare union rates and clinical outcomes between locked volar plate fixation and headless compression screw fixation for the treatment of scaphoid nonunions. Methods A literature search was performed for studies documenting treatment outcomes for scaphoid nonunions from 2000 to 2020. Inclusion criteria consisted of (1) average age > 18 years, (2) primary study using screw fixation, plate fixation, or both, with discrete data reported for each procedure, and (3) average follow-up of at least 3 months. Exclusion criteria consisted of studies with incomplete or missing data on union rates. Data from each study was weighted, combined within treatment groups, and compared across treatment groups using a generalized linear model or binomial distribution. Results Following title and full-text review, 23 articles were included for analysis. Preoperatively, patients treated with plate fixation had significantly longer time from injury to surgery and were more likely to have failed prior surgical intervention. There was no significant difference between union rates at 92 and 94% for screw and plate fixation, respectively. However, plate fixation resulted in longer time to union and lower modified Mayo wrist scores. Conclusion Patients treated with locked volar plate fixation were more likely to be used for recalcitrant or secondary nonunions. There was no statistically significant difference in union rates between screw and plate fixation. The results from this meta-analysis support the select use of locked volar plate fixation for scaphoid nonunion, especially recalcitrant nonunions and those that have failed prior surgical repair.

Novel use of Asopa technique for penile urethrocutaneous fistula repair.

To evaluate the feasibility of ventral urethrotomy, dorsal inlay (Asopa) technique in management of urethrocutaneous fistula. The Asopa technique has been employed for management of urethral stricture repair but has not been described in adult penile urethrocutaneous fistula. This is a retrospective review of IRB-approved databases of patients undergoing urethral reconstruction from two urologic reconstruction units. In this technique, the fistulous tract is circumscribed and excised, leaving a larger ventral urethral defect with healthy edges. The ventral-sagittal urethrotomy is extended, a dorsal urethrotomy made, and a graft inlaid dorsally to augment the urethral caliber prior to tension-free closure of the ventral urethrotomy. From 2010 to 2019, ten patients underwent repair of urethrocutaneous fistula using the Asopa technique. Median patient age was 33.5years (IQR 35.5). All fistulae involved penile urethra, eight had concomitant adjacent urethral stricture. Five patients failed prior hypospadias repair, three developed fistulae after surgery for penile urethral stricture, and two developed fistulae after extensive debridement (hidradenitis and Fournier's gangrene). Of these ten patients, oral mucosa graft was used in nine and preputial graft in one to augment the urethra. At median follow-up of 50.5months (IQR 26.5), 80% (8/10) of patients demonstrated durably patent urethra, with no recurrence of fistula. The Asopa technique is an established option for augmenting urethral caliber for urethral stricture disease. We demonstrate in our series that this technique can be applied to patients with urethrocutaneous fistulae.

Results after Revision Arthroscopic Rotator Cuff Repair: A Prospective Multi-Center Analysis

Primary arthroscopic rotator cuff repair has shown to provide reliable clinical results with a low re-tear rate. Rotator cuff re-tears following surgical repair are associated with poor shoulder function and unsatisfactory clinical results. Data regarding the role of revision arthroscopic rotator cuff repair (RARCR) are sparse. Hence, this study aimed to investigate the clinical and radiological results following RARCR. It was hypothesized that (1) RARCR would lead to an improved clinical outcome and that (2) the clinical results would be dependent on tendon integrity at two years. During a 3-year period, 100 patients who underwent RARCR were prospectively enrolled in this multi-center study of ten European shoulder centers. Clinical results were evaluated pre-operatively, at six months and at two years by the Constant Score (CS), the Oxford Shoulder Score (OSS) and the Subjective Shoulder Value (SSV). Tendon integrity was analyzed by MRI at two years using the Sugaya classification. 13 patients (13%) were lost to follow-up. All clinical scores improved significantly during the study period (CS from 44±16 preoperatively to 58±22 at six months to 69±19 points at two years; OSS from 27±8 preoperatively to 36±11 at six months to 40±9 points at two years; SSV from 43±18% preoperatively to 66±24% at six months to 75±22% at two years; p < .01). At two years, a re-tear rate of 51.7% and a surgical revision rate of 12.6% were observed. While the Sugaya score improved from 4.5±0.9 preoperatively to 3.7±1.4 at two years, tendon integrity could not be correlated with better outcome scores. Prior open rotator cuff repair, involvement of the subscapularis tendon and medial cuff failure were correlated with poorer SSV scores at two years (p < .05). While RARCR leads to an improved clinical outcome, re-tears are frequently observed at a mid-term follow-up. Patients with re-tears, however, do not necessarily have poorer shoulder function than those with healed tendons. Patient satisfaction was lower when the primary surgery was performed by an open technique, when an associated lesion of the subscapularis was present and when the rotator cuff re-tear was located at the musculotendinous junction.

Incidence and Impact of Concomitant Vascular Injuries in Post-Cholecystectomy Bile Duct Stricture: A Prospective Study with MR Angiography

Introduction: Impact of concomitant vascular biliary injury (VBI) on post- cholecystectomy benign biliary stricture (BBS) repair is still debatable with studies both in favor and against. In our study we look for incidence of VBI and impact on long-term outcomes. Methods: Consecutive patients with BBS during the period December 2010 to May 2012 were included. Magnetic resonance angiography (MRA) with MRCP was done prior to repair. Long-term outcomes were analyzed as per McDonald grading. Results: 36 patients were included in the study. Median age was 36 (15-70) years and 28 (78%) were females. 10 patients (28%) had prior failed repair. 23 (64%) patients had high strictures (Bismuth Type ≥3). VBI was present in 22 (61%) involving right hepatic artery (RHA). Of these, laparoscopic cholecystectomy was performed in 18 patients (82%). Additionally right portal vein injury was present in one patient. In patients with prior failed repair 5 (50%) had RHA injury. 34 patients underwent Roux en Y hepaticojejunostomy (RYHJ). Median blood loss was 300ml (range 50-950). Median duration of surgery was 5 hours (range 2-9). Complications were present in 13 (36%) patients. At median follow up of 48 months (24 - 60), there were 8 failures (Success= 76%) requiring re-intervention. Two patients required right hepatectomy. Failed previous repair and secondary biliary cirrhosis were significantly associated with failure. Conclusion: Concomitant VBI has significant impact on long-term outcomes of BBS repair. It will be prudent to do MRA with MRCP during workup of BBS patients for better management planning

Comparison of open and laparoscopic inguinal hernia repair

Inguinal hernia repair is one of the most commonly performed general surgery operations. Throughout the years there have been many variations and advancements, including open and laparoscopic techniques, to accomplish the same task of reducing herniated contents and preventing groin hernia recurrence. An array of factors contributes to deciding which operative technique is the best approach to managing a patient presenting with an inguinal hernia. Published data vary due to the heterogeneity of techniques compared, patient presentations, and surgeon expertise. In experienced hands, laparoscopic repair results in a quicker return to work and reduced postoperative pain. Patients with bilateral groin hernias, female patients with groin hernias, and patients with recurrent hernias after prior anterior mesh repair should be offered a laparoscopic preperitoneal mesh approach, when surgeons have the appropriate skill set and experience. We find that open and laparoscopic techniques of inguinal hernias can both achieve exceptional outcomes when applied to the right patient population. To know one’s own capabilities, it is beneficial for surgeons to have baseline familiarity of the multitude of methods of repair, become proficient in both mesh and mesh-free techniques as well as open and laparoscopic techniques to best tailor the surgery to the patient and the clinical circumstances, and follow personal outcomes to evaluate individual results.

Patients With a History of Oronasal Fistula Repair Exhibit Lower Oral Health Measured With Patient-Centric Outcomes Measures.

Oronasal fistulae following palatoplasty may affect patients' quality of life by impacting their ability to eat, speak, and maintain oral hygiene. We aimed to quantify the impact of previous oronasal fistula repair on patients' quality of life using patient-reported outcome psychometric tools. A cross-sectional study of 8- to 9-year-old patients with cleft palate and/or lip was completed. Patients who had a cleft team clinic between September 2018 and August 2019 were recruited. Participants were divided into 2 groups (no fistula, prior fistula repair). Differences in the individual CLEFT-Q and Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) Oral Health scores between the 2 groups were evaluated using a multivariate analysis controlling for Veau classification and syndromic diagnosis. Sixty patients with a history of cleft palate were included. Forty-two (70%) patients had an associated cleft lip. Thirty-two (53.3%) patients had no history of fistula and 28 (46.7%) patients had undergone a fistula repair. CLEFT-Q Dental, Jaw, and Speech Function were all higher in patients without a history of a fistula repair; however, none of these differences were statistically significant. The COHIP-SF 19 Oral Health score demonstrated a significantly lower score in the fistula group, indicating poorer oral health (P = .05). One would expect that successful repair of a fistula would result in improved function and patient satisfaction, but the consistent trend toward lower CLEFT-Q scores and significantly increased COHIP-SF 19 Oral Health scores in our study group suggests that residual effects linger and that the morbidity of a fistula may not be completely treated with a secondary correction.

Erectile dysfunction in patients undergoing multiple attempts at hypospadias repair: Etiologies and concerns

One-third of adult patients presenting for the repair of persistent penile defects after failing multiple hypospadias repair attempts during childhood will complain of erectile dysfunction (ED). The goal of this paper is to identify possible etiological causes of its onset. Five selection criteria were used for entrance into the study: 1) Patients had to have failed≥three prior hypospadias repair attempts. 2) Present for evaluation between 18 and 40 years of age. 3) No known congenital or medical anomaly could be present that could have predisposed to erectile dysfunction. 4) Sexual history inventory for men (SHIM-5 score) completed. 5) All patients with moderate to severe ED (SHIM scores≤16) underwent psychological screening; individuals with good quality spontaneous or self-stimulated erections, experiencing major life events, or had documented psychological problems were excluded from the study. One hundred consecutive patients meeting these criteria were assessed. We evaluated multiple factors to discern if they were associated with the onset of ED: the initial location of the urethral meatus, if a corporoplasty was performed, the type of corporoplasty used, if the urethral plate was divided or resected, the use of a ventral corporal graft, the total number of open reparative procedures performed before referral, the number of direct visual internal urethrotomies (DVIU) performed, the length of a urethral stricture at the time of the referral and whether lichen sclerosus was present. Statistical evaluations used chi-square analysis, two-tailed t-tests, or a logistic regression model where indicated, p-values < 0.05 were considered significant. 37% (37/100) of our patients complained of moderate to severe ED (SHIM score ≤16). Statistical analysis comparing patients with ED to those without ED (63%:63/100), revealed patients with ED were older, median age 34yrs (range 20-40) vs 26yrs (range 18-40) p=0.0212, had undergone division of the urethral plate 70.3% (26/37) vs 47.6% (30/63), p=0.0276, had placement of a ventral corporal graft, 24% (8/33) vs 1.5% (1/67), p=0.0003 or had undergone repetitive DVIU's to manage urethral stricture disease, median number 4 (range 0-15) vs 0 (range 0-6), p<0.0001, see table. The early onset of ED in patients that failed multiple attempts at hypospadias repair in childhood is associated with advancing age, division of the urethral plate, and prior ventral corporal grafting. Especially significant is the association of ED to the use of repetitive internal urethrotomy to manage urethral stricture disease.

Laparoscopic transabdominal preperitoneal repair for recurrent groin hernia after failed anterior-posterior repair.

The International Guidelines for Groin Hernia Management recommends an anterior repair after a failed posterior repair, and laparoscopic repair after a failed anterior tissue repair or Lichtenstein repair. However, there are not enough studies to guide decision-making for patients with recurrent hernia patients after combined anterior-posterior repair. We investigate the safety and usefulness of transabdominal preperitoneal repair (TAPP) for recurrent hernia patients after failed anterior-posterior repair. We conducted a retrospective analysis of 13 consecutive patients with recurrent groin hernia who underwent TAPP after prior anterior preperitoneal mesh repair (that created anterior and posterior scarring) between September 2013 and October 2018. The control group comprised 45 patients who underwent TAPP for recurrent hernia after anterior repair (43 nonmesh repairs and two Lichtenstein repairs). There were no intraoperative complications, and chronic pain was not reported by the patients with prior anterior preperitoneal mesh repair. The mean operative time was 113 ± 31.3minutes, and the mean postoperative stay was 1.62 ± 0.87 days. The Wong-Baker FACES rating scale score for pain on postoperative day 1 was 1.91 ± 1.5; on postoperative day 7, the score was 1.0 ± 0.89. None of these findings was significantly different from the findings in patients who had a prior anterior repair. A single patient experienced a further recurrence and underwent repeat TAPP. The use of TAPP after failed combined anterior-posterior mesh repair may be feasible and safe for recurrent groin hernia. Further study is needed to determine long-term outcomes.

Prospective analysis of transvaginal mesh hysteropexy in the treatment of uterine prolapse.

The aim of this study was to assess the efficacy of using transvaginal mesh to correct uterine prolapse by hysteropexy. This was a single-center, prospective study of 40 subjects with bothersome uterine prolapse. Inclusion criteria were bothersome perception of a vaginal bulge on Pelvic Floor Distress Inventory short form (PFDI-20) and having a Pelvic Organ Prolapse Quantification System (POP-Q) point C of -2 or worse. Exclusionary criteria included inability to consent, history of pelvic malignancies, or any prior prolapse repair. Eligible subjects were treated with transvaginal mesh hysteropexy between March 2016 and July 2018 for a primary outcome of composite success, which was defined by a POP-Q point C value of -2 or higher, PFDI-20 question 3 indicating no bothersome perception of prolapse, and no retreatment. Secondary outcomes included responses to condition-specific and quality-of-life questionnaires, satisfaction/regret, and complications. Transvaginal mesh hysteropexy was performed in 40 subjects. The majority (68%) had advanced stage (III/IV) uterine prolapse. At a median follow-up of 12months, there was an 84% composite success, and considering only anatomic criteria (POP-Q point C < -1), there was a 92% success. No subject required reintervention for recurrent or persistent uterine prolapse. There were no cases of mesh exposures. In terms of safety, one subject required a blood transfusion for symptomatic anemia (Clavien-Dindo grade II), and one subject reported de novo dyspareunia from a perineal band that was released in office at 6 months (grade IIIa), but otherwise there were no serious immediate or late complications. There were significant improvements in both condition-specific and quality-of-life assessments from baseline. Subject satisfaction and acceptance for the procedure were high. In this single-center case series of 40 women with bothersome uterovaginal prolapse, transvaginal mesh hysteropexy appears safe and effective for correcting advanced stage uterine prolapse at the short term. A future multicenter controlled trial would be needed to determine efficacy against native tissue repair.

Impact of panniculectomy in complex abdominal wall reconstruction: a propensity matched analysis in 624 patients.

In complex abdominal wall reconstruction (AWR), the role of concomitant panniculectomy has been debated due to concern for increased wound complications that impact outcomes; however, long-term outcomes and quality of life (QOL) have not been well described. The aim of our study was to evaluate the outcomes and QOL in patients undergoing AWR with panniculectomy utilizing 3D volumetric-based propensity match. A prospective database from a tertiary referral hernia center was queried for patients undergoing open AWR. 3D CT volumetrics were analyzed and a propensity match comparing AWR patients with and without panniculectomy was created including subcutaneous fat volume (SFV). QOL was analyzed using the Carolinas Comfort Scale. Propensity match yielded 312 pairs, all with adequate CT imaging for volumetric analysis. The panniculectomy group had a higher BMI (p = 0.03) and were more likely female (p < 0.0001), but all other demographics and comorbidities were similar. The panniculectomy group was more likely to have undergone prior hernia repair (77% vs 64%, p < 0.001), but hernia area, SFV, and CDC wound class were similar (all p > 0.05). Requirement of component separation (61% vs 50%, p = 0.01) and mesh excision (44% vs 35%, p = 0.02) were higher in the panniculectomy group, but operative time were similar (all p ≥ 0.05). Panniculectomy patients had a higher overall wound occurrence rate (45% vs 32%, p = 0.002) which was differentiated only by a higher rate of wound breakdown (24% vs 14%, p = 0.003); all other specific wound complications were equal (all p ≥ 0.05). Hernia recurrence rates were similar (8% vs 9%, p = 0.65) with an average follow-up of 28months. Overall QOL was equal at 2weeks, and 1, 6, and 12months (all p ≥ 0.05). Despite panniculectomy patients and their hernias being more complex, concomitant panniculectomy increased wound complications but did not negatively impact infection rates or long-term outcomes. Concomitant panniculectomy should be considered in appropriate patients to avoid two procedures.

Revisional surgery for recurrent benign bile duct strictures

Bile duct injuries during cholecystectomy are not rare and may have significant long-term morbidity. Treatment of these injuries is complex and needs a multidisciplinary approach. This study aims to evaluate the results of revisional surgery performed for recurrent biliary strictures that developed after a prior repair. Patients who had been surgically treated for a major biliary injury during open or laparoscopic cholecystectomy and operated on for recurrent stricture in our institute were reviewed retrospectively. A total of 11 patients who were referred to the surgery clinic were included. The median length of stay after revisional surgery was 9 days (range 5–30 days). Five patients (45%) had experienced at least one postoperative complication. The median follow-up period was 36 months (range 5–69 months). Terblanche clinical scores of all patients were 1 or 2 at their last clinical visit. None of the 11 patients required reoperation and no mortality was seen during the postoperative period. Although revisional biliary surgery for recurrent biliary strictures is a challenging procedure, these revisions can be performed with favorable results. Meticulous preoperative evaluation and implementation of precise surgical technique are essential to achieve long-term success.

Patient-specific metal implants for focal chondral and osteochondral lesions in the knee; excellent clinical results at 2\xa0years

PurposeSurgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or who have failed prior cartilage repair surgery. This study reports on the early clinical and functional outcomes in patients undergoing treatment with an individualised mini-metal implant for an isolated focal chondral defect in the knee.MethodsOpen-label, multicentre, non-randomised, non-comparative retrospective observational analysis of prospectively collected clinical data in a consecutive series of 80 patients undergoing knee reconstruction with the Episealer® implant. Knee injury and Osteoarthritis Outcome Score (KOOS) and VAS scores, were recorded preoperatively and at 3 months, 1 year, and 2 years postoperatively.ResultsSeventy-five patients were evaluated at a minimum 24 months following implantation. Two patients had undergone revision (2.5%), 1 declined participation, and 2 had not completed the full data requirements, leaving 75 of the 80 with complete data for analysis. All 5 KOOS domain mean scores were significantly improved at 1 and 2 years (p < 0.001–0.002). Mean preoperative aggregated KOOS4 of 35 (95% CI 33.5–37.5) improved to 57 (95% CI 54.5–60.2) and 59 (95% CI 55.7–61.6) at 12 and 24 months respectively (p < 0.05). Mean VAS score improved from 63 (95% CI 56.0–68.1) preoperatively to 32 (95% CI 24.4–38.3) at 24 months. The improvement exceeded the minimal clinically important difference (MCID) and this improvement was maintained over time. Location of defect and history of previous cartilage repair did not significantly affect the outcome (p > 0.05).ConclusionThe study suggests that at 2 years, Episealer® implants are safe with a low failure rate of 2.5% and result in clinically significant improvement. Individualised mini-metal implants with appropriate accurate guides for implantation appear to have a place in the management of focal femoral chondral and osteochondral defects in the knee.Level of evidenceIV.

AORTOESOPHAGEAL FISTULA PRESENTING AS HEMATEMESIS AFTER UPPER ENDOSCOPY

SESSION TITLE: Medical Student/Resident Critical Care Posters SESSION TYPE: Med Student/Res Case Rep Postr PRESENTED ON: October 18-21, 2020 INTRODUCTION: Aortoesophageal fistulas (AEFs) are a rare and deadly cause of upper gastrointestinal bleeds. Prior repair of the thoracic aorta, primary aortic aneurysms, foreign body ingestion and thoracic cancer account for more than 90% of AEFs. Here we present the case of a patient developing AEF after a diagnostic esophagogastroduodenoscopy (EGD). CASE PRESENTATION: A 72-year-old male smoker with a history lung cancer status post right lobectomy presented with months of progressive solid dysphagia. In the past months he underwent two EGDs with balloon dilation of esophageal strictures, of which the most recent one was complicated by a distal esophageal perforation requiring an esophageal stent. Weeks after stent removal his dysphagia returned, prompting a repeat EGD to obtain biopsies of his stricture [Figure 1A-B]. The post-operative course was complicated by a small episode of hematemesis, for which the patient was offered admission for observation but declined. After eating his first meal at home, the patient had a second episode of hematemesis which prompted him to present to the emergency department. On admission, the patient was noted to have hematemesis necessitating a rapid response activation. He underwent emergent endotracheal intubation for airway protection and was started on pantoprazole and octreotide infusions. A massive transfusion protocol was initiated, and the patient was transferred to the intensive care unit where he was started on multiple vasopressors for his hypovolemic shock. A stat computed tomography angiogram (CTA) of the chest was suspicious for an underlying aorto-esophageal fistula [Figure 2A-C]. Thoracic surgery was consulted and given the patient’s age and complexity of the procedure; he was deemed a poor surgical candidate. Ultimately the patient’s family decided to pursue comfort care and the patient passed shortly thereafter. DISCUSSION: The presentation of AEF is characterized by a triad of midthoracic pain, sentinel arterial hemorrhage, and massive hemorrhage after a symptom-free interval. While initial clot formation tamponades the fistula, GI contents rapidly weaken this clot. Evaluation for AEF should done with a CTA-Chest as it has been found to be more sensitive than EGD. Initial therapy should focus on achieving hemodynamic stability via thoracic endovascular aneurysm repair or aortic graft replacement. AEF outcomes are improved when the esophageal pathology can be addressed with esophagectomy, stenting, or fistula repair, and with use of post-operative broad-spectrum antibiotics. Prompt surgical intervention increases one-year survival up to 50%. CONCLUSIONS: AEF should be included in the differential of hematemesis after instrumentation for an EGD. Limited time exists between the herald bleed and massive hemorrhage to confirm the diagnosis and plan for a surgical approach. CTA-Chest should be obtained first, followed by an EGD when imaging is inconclusive. Reference #1: Takeno S, Ishii H, Nanashima A, Nakamura K.
