Background Transluminal replacement of a displaced peritoneal catheter (TRC) using a metal guidewire is a noninvasive treatment of catheter displacement with acute malfunction. The “alpha-replacer” is a special guidewire developed specifically for TRC. This wire is usually flexible but becomes harder if coiled in the hand. Application of this unique guidewire might improve the effectiveness of TRC. Methods TRC using an alpha-replacer was performed in 10 cases for urgent correction of peritoneal catheter displacement. All patients had received a double cuffed, straight-end swan-neck catheter. Results The primary success rate of TRC using the alpha-replacer was 90% (9 of 10 cases). No patients developed complications such as injury of the peritoneum or abdominal organs. Relapse of catheter displacement was observed in 2 cases (20%) within 1 week, requiring surgical intervention to prevent relapse. Conclusion TRC using the alpha-replacer as described herein offers effective and safe treatment of peritoneal catheter displacement.

Crural Arteries

In 91 patients suffering from peripheral arterial occlusive disease (Fontaine stage IIb—IV) 125 percutaneous transluminal angioplasties (PTA) of crural arteries were performed. Eighty-six of the dilatations were done in combination with a recanalization procedure (PTA, laser angioplasty, fibrinolysis) of a femoropopliteal obstruction in order to improve outflow. PTA was performed with 5 F balloon catheters 2.5 to 4 mm in diameter in combination with steerable guide wires. A primary technical success was achieved in 41 of 42 (97.6%) vessels with a single stenosis, in 64 of 68 (94.1%) vessels with 2 or more stenoses, and 9 of 15 (60%) vessels with total occlusions (overall primary success rate 91.2%). Complications included spasm (n = 3), thrombosis (n = 2), peripheral embolization (n = 2), and dissection (n = 1). None of the complications required surgical intervention. After PTA, accumulative patency rate of 71% at 2 years and 64.2% at 3 years was achieved. These results demonstrated that PTA of crural arteries is a safe procedure with an excellent primary success rate and satisfying long-term results. Thus we believe that even arterial occlusive disease in the clinical stage Fontaine IIb should be accepted as an indication for crural PTA. Furthermore, crural PTA should be used to improve reduced peripheral outflow after femoropopliteal PTA.

Abstract Funding Acknowledgements Type of funding sources: None. Background Catheter ablation of paraseptal accessory pathways (PAP)  is associated with longer fluoroscopy and procedure times, more radiofrequency lesions, as well as a higher rate of recurrence and complications. In anteroseptal or midseptal PAP, recurrence and risk of AV block is even higher. Guided ablations with a three-dimensional  electroanatomic mapping system  (3D) report greater efficacy and safety. Purpose To assess the acute success rate and complications of PAP 3D catheter ablation. Report the recurrence rate at one year of follow-up. Methods Descriptive analysis that included patients with difficult PAP 3D catheter ablation between 2017 and 2019. Acute success was defined as the disappearance of ventricular pre-excitation 15 seconds after starting the application and the absence of retrograde conduction (Figure). In all cases, a one-year follow-up was performed with ECG and 24-hour Holter. Results 25 patients were included during the mentioned period. The average age was 23 years, 60% (15 p) were men and 56% (14 p) were symptomatic due to palpitations. 1 patient had previous heart disease (ebstein"s anomaly). 36% (9 p) had a previous procedure: 5 patients with previous failed radiofrequency ablation, 1 patient with failed anteroseptal cryoablation and 3 patients with suspended ablation due to risk of AV block. The most frequent location was the posteroseptal. (Table) The primary success rate was 92% (23 of 25 p). Ablation was unsuccessful in two patients, one with Ebstein"s disease and the other with a left posteroseptal PAP. None of the patients presented complications associated with the procedure. During the one-year follow-up, one patient was registered with asymptomatic recurrence (1 of 23; 4.35%: right posteroseptal location), demonstrated by manifest preexcitation on the control ECG. Conclusion In our first experience, catheter ablation of difficult accessory pathways guided by three-dimensional electroanatomic mapping showed a high primary success rate without associated complications. Recurrence during follow-up was similar to that reported in the literature.

Background: There is currently no agreement on the optimal management of caesarean scar pregnancy. Caesarean scar pregnancy is currently categorised into two subtypes according to the site of implantation. This may consequently result in the difference in treatment options. However, the comparison of the success rate of each treatment option according to the subtypes has not been fully investigated.Methods: 71 patients who were treated by uterine curettage (D and C), or uterine artery embolization with curettage (UAE) or hysteroscopy in conjunction with laparoscopy between January 2016 and March 2020 were included. Data on maternal age, gestational sac age, the sac diameter, the interval between two pregnancies, the number of previous caesarean sections, amount of bleeding and β-hCG levels were collected and analysed dependent on the subtypes.Results: There was no difference in the clinical parameters of the cases who received different options of treatment, as well as no difference in the clinical parameters between type 1 and type 2 caesarean scar pregnancy. The primary success rate for type 1 caesarean scar pregnancy by D and C, or UAE, or hysteroscopy in conjunction with laparoscopy was 95, or 100 or 100%, respectively. The primary success rate for type 2 caesarean scar pregnancy by D and C, or UAE, or hysteroscopy in conjunction with laparoscopy was 27, or 67, or 95% respectively.Conclusion: Our data demonstrates that hysteroscopy in conjunction with laparoscopy for type 2 caesarean scar pregnancy was the most successful compared to other options, but for type 1 caesarean scar pregnancy, D and C could be the cost-effective option.

Abstract Purpose To investigate the learning curve of vitreoretinal (VR) surgeons beginning training in retinal detachment (RD) surgery. Methods The files of all consecutive patients undergoing VR surgery for uncomplicated RD between Jan 2005 und Mar 2020 were retrospectively reviewed. Successful outcome was defined as no retinal redetachment within 3 months after surgery. Results Ten surgeons started their VR career during this period. Together, these 10 surgeons performed 3786 RD operations (mean 379; median 251; range 71–1053). Primary success rate after one operation was 90% (3420 of 3786). When starting to operate retinal detachments, VR surgeons had a primary success rate of about 80%. Redetachment rates steadily decreased and stabilized at just under 10% after about 200 operations. Beginners needed more than twice the time for the procedure compared to experienced surgeons. The individual learning curves varied widely. In our series, female surgeons seem to have a faster learning curve. Conclusion RD surgery performed by VR surgeons in training had acceptable results. With increasing experience, success rates continuously improve reaching stable levels after approximately 200 operations. The training of VR surgeons requires considerable resources.

Objectives Although the flexible laryngeal mask airway (FLMA) provides considerable advantages in head and neck procedures, little is known about its safety and efficacy in functional endoscopic sinus surgery (FESS). We conducted a retrospective study to evaluate the success rate of FLMA and relevant airway complications in FESS under general anaesthesia. Methods A retrospective review of consecutive patients who underwent FESS for chronic rhinosinusitis was performed from 2015 to 2019. All patients scheduled for FLMA ventilation were identified. Patient characteristics, length of the surgery, FLMA size, failed FLMA cases requiring endotracheal intubation, immediate adverse airway events and delayed airway injuries were recorded. The primary outcomes included the FLMA success rate, which was defined as primary success after induction and final success after the whole surgical procedure. The secondary outcomes were specific clinical factors associated with FLMA failure and airway complications related to FLMA usage. Results Of the 6661 patients included in our study, primary success was achieved in 6572 (98.7%), and final success was achieved in 6512 (97.8%). Failure occurred in 89 patients (1.3%) during induction, in 14 (0.2%) during surgical preparation and in 46 (0.7%) during the intraoperative procedure. All patients with failed FLMA ventilation were successfully switched to endotracheal intubation. Male sex, advanced age, higher American Society of Anesthesiologists grade (ASA) and higher body mass index (BMI) were independent risk factors associated with failed FLMA. Immediate adverse respiratory events were observed in 0.85% of the patients, and delayed airway injuries associated with use of FLMA were observed in 0.07%. Conclusion This retrospective study demonstrates a high success rate for FLMA (97.8% in 6661 patients undergoing FESS). Adverse airway events and injuries associated with FLMA are rare, but clinicians should remain vigilant so that early diagnosis and prompt treatment can be provided.

AbstractThe success rate of eighth nerve section in abolishing tinnitus is disappointing and the results generally unpredictable. A comparison of the effects of a bolus intravenous injection of lidocaine with the effects of nerve section is reported: it presents some evidence that the response to lidocaine may be of value in selecting patients for nerve section, and further it may shed some light on the site of action of lidocaine in suppressing tinnitus.
