Abstract Background Ureteroscopic lithotripsy is a common treatment for middle and lower ureteral stones. Although effective and minimally invasive, this technique might cause significant complications, including postoperative ureteral strictures, which occur in 1–4% of patients after ordinary ureteroscopic lithotripsy and in 7.8–24% when lithotripsy is performed for impacted stones. The main purpose of the management of ureteral strictures is to improve hydronephrosis and protect renal function. However, factors that influence the success rate of the endoscopic management of US (e.g., the cause and length of stricture, the duration of hydronephrosis, surgical management technique, and the number of placed ureteral stents) are controversial. The aim of this study was to investigate factors determining the outcomes of endoscopic management for stone-related ureteral stricture. Methods This multi-center case series study was performed at one of the highest-volume centers and the affiliated institutions in Japan. Data of patients who underwent endoscopic surgery for ureteral stricture from January 2016 to March 2019 were retrospectively analyzed. Laser incision and/or balloon dilation were performed for management; single or double stents were placed at the end of the surgery. Treatment success was defined as improvement in hydronephrosis status. Results Nineteen patients were treated for stone-related ureteral stricture. Hydronephrosis successfully improved in 12 patients (63.2%). All seven patients with failed endoscopic management had ureteroscopic lithotripsy-related stricture, whereas 3/12 (25.0%) and 7/12 (58.3%) patients with ureteroscopic lithotripsy-related stricture and impacted stone-related stricture, respectively, underwent successful endoscopic treatment (P = 0.004). Stricture length > 15 mm was observed in five patients (71.4%) with failed management, two patients (16.6%) with successful management (P = 0.046), 7/10 patients (70.0%) with ureteroscopic lithotripsy-related stricture, and 1/7 patients (14.3%) with impacted stone-related stricture (P = 0.049). Among patients with ureteroscopic lithotripsy-related stricture and impacted stone-related stricture, both laser incision and balloon dilation were performed in 5/10 (50.0%) and 2/7 (28.6%) patients (P = 0.874) while double stents were placed in 5/10 (50.0%) and 5/7 (57.1%) patients (P = 0.874), respectively. Conclusions Ureteroscopic lithotripsy as a cause and stricture length > 15 mm could strongly affect the success rate of endoscopic management of ureteral stricture. In such cases, reconstructive management should be considered in the early stages.

Introduction and Objectives Ureteral stenosis and vesicocoureteral reflux after renal transplantation represent a key concern because of their incidence and the associated morbidity. Prompt diagnosis and minimally invasive treatment are mandatory in immunosuppressed patients with single kidney. The aim of this study is to evaluate the success rate of the endourological techniques in the management of such complications. Materials and Methods Between January 1996 and December 2006, 647 kidney transplants were performed. Urinary tract continuity was re-established by ureteroneocystostomy according to Gregoir-Lich technique. We observed 13 cases of ureteral stenosis (2%) and 11 cases of symptomatic vesicoureteric reflux (1.7%). The endourogical procedure was performed in 13 patients: 5 cases of II-III grade vesicoureteric reflux, 4 early ureteral stenosis and 4 late ureteral stenosis. Patients with vesicoureteric reflux underwent endoscopic injection of macroplastique in 4 cases and Durasphere in 1. Early ureteral stenoses were treated using balloon dilation in 2 cases, balloon dilation and laser endoureterotomy in 3, ureteral stent placement in the other. Recipients with late stenosis underwent laser incision and balloon dilation in 2 cases, balloon dilation in 1 and a laser incision only in the last case. Combined antegrade and retrograde endoscopic approach was performed in 7 patients, whereas retrograde access in 1. Results Endourologic treatment was successful in 9 cases (69.2%); 2 patients required open reconstructive surgery due to endourological technique failure (early ureteropelvic junction stricture, late ureterovesical anastomotic stricture). Vesicoureteric reflux was corrected in 3 patients (60%), 2 patients underwent uretero-ureterostomy for recurrent reflux. No technique-related morbidity was observed. With a mean follow-up of 81.6 months, 8 patients show normal renal function, 5 patients have returned to haemodialysis (4 for chronic rejection, 1 for carcinoma in the graft). Conclusions Considering their low morbidity and the satisfactory success rate, we claim that endourological procedures should be considered the preferred treatment for ureteral stenosis and vesicoureteric reflux in selected patients.

Abstract Introduction: To compare the results and complication rates of a 25-gauge pars plana vitrectomy (25g PPV) with gas tamponade for rhegmatogenous retinal detachment (RRD) between experienced and inexperienced surgeons.Materials and Methods: This is a retrospective comparative consecutive case series study of patients with uncomplicated RRD treated with 25g PPV with gas tamponade. Patients were divided into 2 groups: In Group 1 (ESG) the procedure was performed by an experienced vitreoretinal surgeon and in Group 2 (ISG) the procedure was performed by 2 inexperienced surgeons. Anatomical and functional results and complication rates were compared between the two groups.Results: 216 eyes were included in the study. In the ESG (106 eyes), the single operation success rate was 94.3%, and the final success rate was 100%. The mean best-corrected visual acuity (BCVA) improved from 0.38 decimal to 0.73 decimal. In the ISG (110 eyes), the single operation success rate was 93.6%, and the final success rate was 100.0%. The mean BCVA improved from 0.33 decimal to 0.74 decimal. The differences between groups were not statistically significant. There was no difference in complication rates between groups.Conclusions: A 25g PPV with gas tamponade for treatment of RRD yields excellent anatomical results and improvement in BCVA. With good technique and use of modern vitrectomy machines and instruments, even inexperienced surgeons can achieve high single operation success rate, suggesting a short learning curve. The complication rate is comparable between experienced and inexperienced surgeons.

Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic biliary drainage (PTBD) are the standard of care in malignant biliary obstruction cases. Recently, endoscopic ultrasound-guided biliary drainage (EUS-BD) has been widely used after unsuccessful ERCP. However, the patient’s clinical impact of EUS-BD over PTBD is still not obvious. Therefore, this case series study aims to evaluate the clinical outcomes of patients with advanced malignant biliary obstruction who underwent EUS-BD after failed ERCP. A retrospective database study was performed between January 2016 and June 2018 in patients with advanced malignant biliary obstruction. Patients were consecutively enrolled without randomization. Treatment options consisted of ERCP and PTBD or EUS-BD if ERCP failed. Based on 144 biliary obstruction cases, 38 patients were enrolled; 24 (63.2%) were men. The patients’ mean age was 66.8 ± 12.36 years. The most common cause of malignant biliary obstruction was pancreatic cancer (44.7%). Biliary drainage was achieved by ERCP (39.5%), PTBD (39.5%), and EUS-BD (21.1%). The technical success rate was 86.7% by PTBD and 87.5% by EUS-BD (p = 1.000), while the clinical success rate was 93.3% by PTBD and 62.5% by EUS-BD (p = 0.500). The median survival in patients who underwent PTBD versus those wo underwent EUS-BD was 11 versus 3 months (log-rank p = 0.455). In conclusion, there is no significant advantage of EUS-BD when compared to PTBD in terms of clinical success and survival benefit in advanced malignant biliary obstruction.

Introduction: Acute limb ischemia is a critical medical condition that can quickly become a life threat. Therapeutic modalities such as catheter-directed thrombolysis (CDT) have demonstrated various levels of efficacy in previous studies. Objective: This study presents the descriptive findings of a series of cases who presented with acute arterial thrombotic limb ischemia and underwent CDT. Methods: This was a cross-sectional single-hospital-based case series, in which all patients who were diagnosed with acute arterial thrombotic limb ischemia, and consequently underwent CDT during the oneyear study period were included. Detailed baseline characteristics and clinical findings of the studied patients on presentation, after intervention and at one-year follow-up are presented. Results: A total of 21 patients with a mean age of 60.7±15.2 years, including 16 males (76.2%) were included. The initial technical and treatment success rates were 20 (95.2%) and 14 (66.7%), respectively. The amputation-free and the overall survival rates after the one-year follow-up were 15 (71.4%) and 17 (81%), respectively. Four patients (19%) developed complications, two (9.5%) of which were significant (pulmonary hemorrhage and intraventricular hemorrhage). Amputation was performed in 6 (28.6%) cases. Conclusion: In this study, the treatment success rate and the technical success rate were satisfactory.

Abstract Background The feasibility and safety of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasms extending to the cervical esophagus currently remain unknown because of the limited number of cases. We aimed to clarify the clinical outcomes of these cases. Methods This was a case series study conducted at a single institution that enrolled 26 consecutive patients with superficial esophageal neoplasms extending to the cervical esophagus who underwent ESD between July 2003 and December 2015. Results En bloc and complete resection rates were both 100 % and no major intraprocedural complications occurred. Thirteen patients were treated with prophylactic steroid therapy. The incidence of postoperative stricture in patients with a circumferential mucosal defect of more than three-quarters was 72.7 %. Four patients required entire circumferential resection, with perforation occurring after endoscopic balloon dilation (EBD) in two and EBD being required for more than 1 year in the other two. Conclusions ESD including the cervical esophagus is technically feasible. Circumferential resection may cause refractory postoperative stricture or post-EBD perforation, so needs to be avoided where possible.

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.

ObjectivesTo evaluate the feasibility, safety, and efficacy of Solitaire stent placement after balloon angioplasty for the treatment of complex symptomatic intracranial atherosclerotic stenosis (ICAS).MethodsWe retrospectively reviewed the clinical data from 44 patients who underwent Solitaire stent placement for complex symptomatic ICAS at our department between November 2010 and March 2014, with focus on the clinical factors, lesion characteristics, treatment results, and periprocedural complications. We also summarized the early outcomes and imaging findings during the follow-up period.ResultsOverall, the technical success rate was 100% (44/44). Post-stenting residual stenosis ranged from 0% to 40% (mean 15.00±12.94%). The overall 30-day rate of procedure-related complications was 9.09% (4/44). The incidence of recurrent ischemic events related to the territory artery was 4.55% during a mean clinical follow-up period of 25.5 months. Five patients (11.36%) developed in-stent restenosis during a mean angiographic follow-up period of 9.3 months.ConclusionsThis is the first case series study of ICAS treated by Solitaire stent placement. Deployment of a Solitaire stent with balloon angioplasty in the treatment of complex severe intracranial stenosis appears safe and effective, with a high technical success rate, relatively low periprocedural complication rate, and favorable outcome during follow-up.

Objective This study compared surgical outcomes between free plate Ahmed glaucoma valve (FPAGV) implantation without plate fixation and conventional Ahmed glaucoma valve (CAGV) implantation with plate fixation. Methods A retrospective, comparative case series study. Patients with refractory glaucoma who underwent FPAGV or CAGV implantation and were followed >1 year were enrolled consecutively. We reviewed medical records, including data on postoperative intraocular pressure (IOP) and postoperative complications. The success rate and early postoperative hypertensive phase were compared between groups. Results A total of 74 patients with CAGV implantations and 36 patients with FPAGV implantations were studied. The average follow-up periods were 23.3 ± 2.6 months (CAGV) and 22.8 ± 2.8 months (FPAGV; p = 0.424). The surgery time was significantly shorter in the FPAGV group than in the CAGV group (42.6 ± 4.1 vs. 47.3 ± 5.4 min; p < 0.001). Postoperative IOP at 1 week and 1 month were significantly lower in the FPAGV group than in the CAGV group (11.8 ± 3.6 and 14.0 ± 5.3 mmHg vs. 18.7 ± 5.5 and 22.2 ± 5.2 mmHg; p = 0.012 and p = 0.002, respectively). An early postoperative hypertensive phase occurred in 62 eyes, and the frequency was greater in the CAGV group (50 eyes) than the FPAGV group (12 eyes; p = 0.001). There was no significant difference in postoperative complications between the two groups (p = 0.735). The success rate was 84.2% in the FPAGV group and 80.6% in the CAGV group 24 months after surgery (p = 0.367). Conclusion FPAGV implantation was associated with a shorter surgery time, without any change in the extent of IOP reduction or complication rate. This procedure may be considered a good alternative for CAGV implantation in patients with refractory glaucoma.

Objective. To evaluate and compare the clinical effects of Ahmed glaucoma valves (AGVs) and EX-PRESS implants on glaucoma secondary to silicone oil (SO) emulsification. Methods. A retrospective case-series study was designed. A total of 23 eyes with late intraocular pressure (IOP) elevation secondary to SO emulsification were included in the study. Antiglaucoma surgery with implantation of AGVs or EX-PRESS devices was performed. Pre- and postoperative ocular parameters were recorded at each visit during a 1-year follow-up period. The rates of complete success (IOP < 21 mmHg without medication) and qualified success (IOP < 21 mmHg with ≤3 glaucoma medications) were analyzed. Results. A total of 14 eyes underwent AGV implantation, and 9 underwent EX-PRESS implantation. The mean IOP and number of medications used at the last follow-up decreased significantly compared with that before surgery (P<0.001). The total success rate for all eyes including complete success (7/23) and qualified success (7/23) was 60.9% (14/23) at 1 year. The total success rate in the AGV group was 78.6% (11/14), whereas it was 33.3% (3/9) in the EX-PRESS group; the difference between the 2 groups was significant (P<0.05). Conclusion. For glaucoma secondary to SO emulsification, glaucoma implants could be effective at lowering IOP, and AGVs might produce better outcomes than EX-PRESS devices.
