Background: Percutaneous, transverse distal metatarsal osteotomy with K-wire fixation (the Bösch technique) is an established technique for hallux valgus correction. Nevertheless, the risk of damaging the anatomical structures during the operation is unknown. Methods: Forty fresh-frozen anatomical foot specimens with hallux valgus deformity underwent a percutaneous corrective procedure. Specimens of group A (n = 20) were operated by an experienced surgeon while specimens of group B (n = 20) were done by untrained residents. Results: The dorsal cutaneous nerve was injured in 1 of 20 cases in group A and 6 of 20 cases in group B ( P = .037). There was a significant difference in overall complication rate between specimens of group A and group B ( P = .043). Conclusions: The results show an increased risk of perioperative injury of the dorsal cutaneous branch of the deep peroneal nerve as well as a significant effect of the surgeon’s experience on the overall complication rate. Clinical Relevance: Results of this study are highly relevant for all surgeons who perform percutaneous, minimally invasive hallux valgus surgery to avoid damage to the peripheral nerves. In addition, the data suggest an intensive training for surgeons before minimally invasive hallux valgus surgery is performed without supervision.

Abstract Background The quest for better patient outcomes is driving to the development of minimally invasive spine surgical techniques. There are several evidences on the use of microsurgical decompression surgery for degenerative lumbar spine stenosis; however, few of these studies compared their outcomes with the traditional laminectomy technique. Objectives The aim of our study was to compare outcomes following microsurgical decompression via unilateral laminotomy for bilateral decompression (ULBD) of the spinal canal to the standard open laminectomy for cases with lumbar spinal stenosis. Subjects and methods Cases were divided in two groups. Group (A) cases were operated by conventional full laminectomy; Group (B) cases were operated by (ULBD) technique. Results from both groups were compared regarding duration of surgery, blood loss, perioperative complication, and postoperative outcome and patient satisfaction. Results There was no statistically significant difference between both groups regarding the improvement of visual pain analogue, while improvement of neurogenic claudication outcome score was significant in group (B) than group (A). Seventy-three percent of group (A) cases and 80% of group (B) stated that surgery met their expectations and were satisfied from the outcome. Conclusion Comparing ULBD with traditional laminectomy showed the efficacy of the minimally invasive technique in obtaining good surgical outcome and patient satisfaction. There was no statistically significant difference between both groups regarding the occurrence of complications The ULBD technique was found to respect the posterior spinal integrity and musculature, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods than the open laminectomy technique.

Category: Bunion Introduction/Purpose: Kirschner-wires fixation, sometimes we have encountered pin irritation or pull-out. This is the reason why we consider additional fixation. Moreover, there are few reports according to comparison of fixation method, and Most of them focused on comparison K-wires or screw fixation only. Purpose of study is to compare clinical and radiographic outcome between Kirschner-wires only and combined screw fixation. Methods: The study included two different groups according to fixation methods. One with Kirschner-wires fixation (KW group) included 117 feet(of 98 patients), the other with combined screw fixation (KWS group) 56 feet (of 40 patients) with moderate to severe hallux valgus. Clinically, the preoperative and final follow-up visual analog scale (VAS) pain scores, the preoperative and final follow-up American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal (MTP)-interphalangeal (IP) scores, and patient satisfaction after the surgery were evaluated. Radiographically, the hallux valgus angle (HVA), intermetatarsal angle (IMA), medial sesamoid position (MSP), and first to fifth metatarsal width (1-5MTW) were analyzed before and after surgery. Results: The mean AOFAS score improved preoperative 65.5 to 95.3 at final follow up in group A, while preoperative 56.5 to 88.6 at final follow up. Pain VAS decreased from 5.7 to 0.5 in group A, whereas from 6.2 to 1.6 in group B. The mean HVA all improved from preoperative 38.5 to 9.3 at final follow up in group A and 34.7 to 9.1 in group B. The mean IMA and MSP also improved significantly at final follow up. In comparative analysis, the IMA did not show significant difference between postoperative and final state in group A, while showed significant increase in group B. Conclusion: We achieved favorable clinical and radiographic outcomes with minimal complications in patient with moderate to severe hallux valgus in both groups. However, this study shows no statistically significant difference in IMA during follow-up period and lower recurrence rate. Therefore we need to consider combined fixation method to provide better stability and can expect lower recurrence rate.

Background Computed tomography (CT)-guided percutaneous lung biopsy is usually performed by helical scanning. However, there are no studies on radiation dose, diagnostic accuracy, image quality, and complications based on axial scan mode. Purpose To determine radiation dose, accuracy, image quality, and complication rate following an ultra-low-dose (ULD) protocol for CT-guided lung biopsy in clinic. Material and Methods A total of 105 patients were enrolled to receive CT-guided lung biopsy. The use of an ULD protocol (axial scan) for CT-guided biopsy was initiated. Patients were randomly assigned to axial mode (Group A) and conventional helical mode (Group B) CT groups. 64-slice CT was performed for CT-guided pulmonary biopsy with an 18-G coaxial cutting biopsy needle. The radiation dose, accuracy, image quality, and complication rate were measured. Results Ninety-seven patients were selected for the final phase of the study. There was no significant difference between the two groups for pulmonary nodule characteristics ( P > 0.05). The mean effective dose in group A (0.077 ± 0.010 mSv) was significantly reduced relative to group B (0.653 ± 0.177 mSv, P < 0.001). There was no significant difference in accuracy, image quality, and complication rate ( P > 0.050) between the two modes. Conclusion An ULD protocol for CT-guided lung nodule biopsy yields a reduction in the radiation dose without significant change in the accuracy, image quality, and complication rate relative to the conventional helical mode scan.

Background: Severe postsurgical pain continues to be hard to manage in patients who experience breast cancer surgery. Badly managed pain can lead to meager patient satisfaction, prolonged hospital stay, and increased risk of complication by analgesics, and may be a reason in the development of long-lasting pain. Aim: To compare the efficacy of Intravenous Tramadol and Bupivacaine irrigation through surgical drains after Modified Radical Mastectomy in patients with carcinoma breast. Methods: This was a randomized controlled trial conducted in the Department of Anesthesia, Mayo Hospital Lahore. Total 70 female patients aged 18-70 years undergoing radical mastectomy for CA breast diagnosed on histopathology were selected. Patients were divided into two groups A and B through simple random sampling technique. Group A received intravenous Tramadol. Group B received Bupivacaine through surgical drains. Results: At 0, 2, 4 and 6 hour postoperatively no significant difference was seen in severity of pain in both treatment groups. In Group-A at 0, 2, 4 and 6 hour postoperatively, 68.8%, 71.4%, 57.1% and 60% respectively had reported no pain while in Group-B at 0, 2, 4 and 6 hour postoperatively, 48.6%, 65.7%, 45.7% and 54.3% patients had reported no pain. Complaints of Nausea, vomiting, sedation, urinary retention was higher in patients in Tramadol Group as compared to Bupivacaine Group. Conclusion: Results of this study demonstrated that bupivacaine administrated through surgical drain was equally effective as intravenous tramadol for controlling postoperative mastectomy pain with less side effects.

Introduction. Conflicting results have been reported about the true impact of intradiverticula ampulla (IA) on the technical success and complication rate of endoscopic retrograde cholangiopancreatography (ERCP). Patients. A total of 500 patients who underwent ERCP were divided into two groups according to the presence (group A, 81 patients) or absence (group B, 419 patients) of IA. Success rate, difficulty at cannulation, findings at ERCP, and procedure-related complications were retrospectively reviewed. Results. Successful cannulation was achieved in 100% of group A patients compared to 98% of group B patients (P = ns). There was a significant difference in the type of cannulation that was routinary in group B (), while requiring guidewire in group A (). Cholangitis (), microstones (), dilated common bile duct without stones (), stone recurrence (), and transient postprocedure hyperamylasemia () were more frequently observed in group A. There was no significant difference in complication rate between both groups. Conclusions. The finding of an IA at ERCP should not be considered a predictor for failed cannulation. IA is associated with post-ERCP transient hyperamylasemia and is a risk factor for biliary stone disease and its recurrence.

Abstract Purpose Minimally invasive surgery using short stems in total hip arthroplasty gained more popularity. The differences in change of hip offset and implant positioning in minimally invasive approaches are not fully known. Therefore, this study was conducted to evaluate the difference in reconstruction of hip offset and implant positioning in direct anterior approach (DAA) and minimally invasive anterolateral approach (AL MIS). Methods A single surgeon series of 117 hips (117 patients; mean age 65.54 years ± 11.47; index surgery 2014–2018) were included and allocated into two groups: group A (DAA) with 70 hips and Group B (AL MIS) with 47 patients operated. In both groups the same type of cementless curved short hip stem and press fit cup was used. Results Both groups showed an equal statistically significant increase of femoral (p < 0.001) and decrease of acetabular offset (p < 0.001). Between both groups no statistically significant difference in offset reconstruction, leg length difference or implant positioning could be found. Leg length increased in both groups significantly and leg length discrepancy showed no difference (group A: − 0.06 mm; group B: 1.11 mm; p < 0.001). A comparable number of cups were positioned outside the target zone regarding cup anteversion. Conclusion The usage of a curved short stem shows an equal reconstruction of femoro-acetabular offset, leg length and implant positioning in both MIS approaches. The results of this study show comparable results to the existing literature regarding change of offset and restoration of leg length. Malposition of the acetabular component regarding anteversion poses a risk.

Category: Other; Bunion; Midfoot/Forefoot Introduction/Purpose: There is no standard guideline for prescription opioids for postoperative pain management following outpatient foot and ankle surgery. Multiple previous studies demonstrated that opioids were overprescribed. The purpose of this study was to prospectively investigate opioid consumption using multimodal analgesia regimen after two of the most common forefoot surgeries: isolated hallux valgus correction or 1st metatarsophalangeal (MTP) joint arthrodesis. Methods: We prospectively investigated opioid prescription and consumption of total 21 patients who underwent isolated hallux valgus correction with distal soft tissue procedure and proximal first metatarsal crescentic osteotomy or 1st MTP joint arthrodesis. Postoperative pain was managed using multimodal analgesia including oxycodone, ibuprofen, acetaminophen, and regional ankle block. Patients were instructed to take 5mg of oxycodone every 4 hours as needed, and 600 mg of ibuprofen as well as 1,000 mg of acetaminophen every 8 hours regularly. The number of pills patients consumed for oxycodone was recorded at postoperative follow-up at 1-week, 2-week, 4-week, 8-week, and 12-week. Subgroup analysis was performed to evaluate opioid consumption according to the prescription type: Only oxycodone was prescribed in group A while oxycodone as well as prescription strength ibuprofen and acetaminophen were prescribed in group B. Another subgroup analysis in opioid consumption was performed based on the quantity of opioid prescription and procedure type. Results: The overall mean opioid consumption in 12 weeks of the postoperative period was 16.2 pills per patient with an average of 37.3 pills prescribed. Lower opioid consumption was noted in group B when prescription ibuprofen and acetaminophen were prescribed compared to group A when patients took over-the-counter (OTC) ibuprofen and acetaminophen: 9.0 pills vs 24.1 pills, respectively (P = 0.036). There was a trend showing higher opioid consumption in patients prescribed greater than 30 pills of oxycodone compared to less than or equal to 30 pills: 22.0 pills vs 9.8 pills, respectively (P = 0.099). No significant difference was found in opioid consumption according to the procedure type: 15.8 pills in hallux valgus correction vs 16.5 pills in 1st MTP joint arthrodesis (P = 0.750). Conclusion: This study showed that on the average, patients took 16.2 pills out of 37.3 pills of the prescribed oxycodone after isolated hallux valgus correction or 1st MTP joint arthrodesis using our multimodal analgesia regimen. Patients who were prescribed prescription strength ibuprofen and acetaminophen consumed opioid significantly less than those who took the OTC strength. No significant difference was noted in opioid consumption between isolated hallux valgus correction and 1st MTP joint arthrodesis.

Abstract Background Scheduled electrical cardioversion (CV) of persistent atrial fibrillation (AF) can be performed after an adequate period of oral anticoagulation (OAC) therapy to reduce thromboembolic complications. Exclusion of left atrial appendage (LAA) thrombi can be achieved by transoesophagel echocardiography (TOE), that is indicated if early CV is desired in patients (pts) with ≥48 hours-lasting arrhythmia, while is not recommended after at least 3 weeks of OAC. Purpose We investigated with TOE the presence of LAA thrombi in a consecutive series of ambulatory pts scheduled for electrical CV of AF and treated with DOAC for at least 3 weeks. Methods We evaluated 93 pts referred to our Clinic for CV of persistent AF (October 2017–December 2018), all treated with DOAC. We collected clinical history, physical examination, 12-lead ECG, lab tests and transthoracic echocardiography measures. Right before cardioversion we systematically performed TOE to exclude LAA thrombi. If absent, we proceeded to CV, while in case of grade III echo-contrast and/or thrombotic stratification we didn't perform the procedure. All values are reported, as appropriate, as mean±SD or number and percentage. All results were considered statistically significant when p<0.05. The entire analysis was performed using the Statistical Package for Social Sciences package, version 19.0 (SPSS, Chicago, Illinois). Results 76 out of 93 pts (82% – group A) were free from intracavitary thrombi and underwent successful electrical CV; the other 17 pts (18% – group B) had thrombi in LAA that contraindicated electrical CV. Group B pts (74±10 years old, 65% male sex) had higher CHA2DS2-VASc score (4,1±2 vs 3,1±1,4, p=0,014), they were significantly more affected by chronic kidney disease (CKD, 59% vs 32%, p=0.035), peripheral artery disease (PAD, 35% vs 12%, p=0.017), they had larger LA dimension (48±5 vs 45±5 mm, p=0,09 - non significant) and as expected they had reduced LAA emptying velocity (76% vs 30%, p<0.001) compared to group A pts (73±8 years old, 70% male sex). There was no significant difference neither in duration (median 7 weeks) nor in type of DOAC therapy between the two groups. Conclusions Current Guidelines recommend at least three weeks of OAC before electrical CV of persistent AF. TOE is recommended only if early cardioversion is needed. We observed that in a significant part of pts treated with DOAC for more than 3 weeks TOE still identified LAA thrombi, especially in pts with multiple comorbidities. Even if we currently don't have data on clinical endpoints in this population, CV of patients with LAA thrombi despite adequate DOAC therapy may lead to an increased risk of thromboembolic events. We think it's necessary to identify more accurate predictors (i.e. CKD) to stratify the thromboembolic risk. Further randomized studies are needed to identify whether there are patients in which CV shouldn't be performed without TOE, irrespective of anticoagulation duration.

Abstract Funding Acknowledgements Type of funding sources: None. Background Patients with structural and electrical heart disease are at increased risk for sudden cardiac death. Guidelines recommend the use of an implantable loop recorder (ILR) in symptomatic patients when symptoms are sporadic and suspected to be related to arrhythmias. In clinical practice, an ILR is mainly used in patients with unexplained syncope. Purpose To compare the clinical value of an ILR in patients with a heart disease and a history of syncope versus those with non-syncopal suspected arrhythmia-related symptoms. Methods In this observational single-center study we included symptomatic patients with structural or electrical heart disease who received an ILR. The primary endpoint was an actionable event which was defined as an arrhythmic event leading to a change in clinical management. The secondary endpoint was an event leading to implantation of a pacemaker or implantable cardioverter-defibrillator (ICD). Results A total of 120 patients (mean age 47 ± 17 years, 49% men) were included. Underlying disease substrate was inherited cardiomyopathy (31%), congenital heart disease (28%), channelopathy (23%), and other structural heart disease (18%).There were 43 patients with a history of syncope (group A) and 77 patients with non-syncopal symptoms (group B) such as palpitations, dizziness and/or near-syncope at baseline. During a median follow-up of 19 months (IQR 8-36), a primary endpoint was reached in 14 patients (33%) of group A, and in 28 patients (36%) of group B (logrank P = 0.54, Figure A). There was also no significant difference in the cumulative rate of cardiac device implantation between group A and B, 14% versus 10%, respectively (logrank P = 0.97, Figure B). Conclusion Our results show no differences in ILR yield in patients with structural or electrical heart disease who present with any suspected arrhythmia-related symptom, including those with non-syncopal symptoms.
