Urethroplasty among Elderly Men, Surgical Techniques and Outcomes

Introduction: Urethroplasty remains the gold standard for the management of urethral stricture. However, the treatment of stricture disease in the elderly tends to be less invasive due to the presumption that they might not be able to stand long hours of surgery and might have higher rates of recurrence due to poor wound healing from microangiopathy. We present our experience with the outcomes of urethroplasty among elderly men seen at the Komfo Anokye Teaching Hospital from January 2012 to December 2021. Methods: This was a retrospective review of data captured in the urology database on all patients 65 years and above who underwent urethroplasty at the hospital over the study period. Data was obtained on patients’ demographics, stricture characteristics, urethroplasty technique, and outcome. A successful outcome was defined as peak flow rate > 15 mls/s, a patent urethra on retrograde urethrogram, patient satisfaction with urine stream, or restoration of the normal stream of urine with only one attempt at urethral calibration or internal urethrotomy postoperatively. Data was analyzed using PASW Statistics for Windows, Version 18.0. Results: Overall, 43 urethroplasties were done over the study period in elderly men. The age range was 65 to 87 years. The commonest aetiology was catheterization (62.79%) followed by urethritis (32.56%). Stricture length ranged from 0.5 cm to 16 cm with a mean of 3.93 cm. Most patients (60.46%) had bulbar urethral strictures. The repair methods employed were anastomotic urethroplasty (62.80%), fasciocutaneous flap (FCF) ventral onlay (13.95%), buccal mucosa graft (BMG) ventral onlay urethroplasty (4.65%), and staged urethroplasty (4.65%). Three of the patients (6.98%) had a combination of anastomotic and tissue transfer urethroplasty. The overall success rate was 88.37%. Complications included three surgical site infections, two urethral diverticula and one glans dehiscence. Conclusion: Elderly men tolerate urethroplasty well and the procedure should not be denied solely based on age.

Surgical Technique and Efficacy Analysis of Extra-pseudocapsular Transnasal Transsphenoidal Surgery for Pituitary Microprolactinoma

Objective To elucidate the role of transsphenoidal surgery in the treatment of pituitary microprolactinoma.Methods The clinical data of 107 prolactinoma cases treated by extra-pseudocapsular transnasal transsphenoidal surgery(ETTS)for different indications in our department since 2011 was retrospectively analyzed.Results The most common indication was the ineffectiveness of oral medication(41.1%),followed by the personal willingness of the patient(35.5%),and 20.6%of the patients were young women with clear tumor boundaries.The pseudocapsule was not observed in 63 cases(58.9%),incomplete pseudocapsule was observed in 26 cases(24.3%),and complete pseudocapsule in 18 cases(16.8%).A total of 97 patients(90.7%)obtained 1-year post-operation remission.According to the relative location of the adenoma and pituitary gland on the MRI scan,46 patients were classified into a central type,59 a lateral type,and 2 a supra-pituitary type.Two patients developed hypogonadism,one patient developed hypocortisolism,and one patient developed post-operative hypothyroidism.Two patients were administrated with hormone replacement treatment,and the treatment was stopped within one week.There was no permanent hypopituitarism.Further investigation demonstrated that the adenoma types could affect the remission rates of hyperprolactinemia and gross total resection rate in microprolactinoma.Conclusion ETTS was an effective treatment for pituitary microprolactinomas.This could be the first choice for patients who presented enclosed adenoma on the MRI and were potentially curable in a preoperative evaluation.Maximal safe removal of the adenoma by ETTS with the aim to increase the sensitivity of the drugs was also recommended for patients with invasive dopamine agonist resistant prolactinomas and patients with difficulty in childbirth.

Adjustable muscle plication:a new surgical technique for strabismic patients with high risk for anterior segment ischemia

【正】INTRODUCTION Anterior ciliary arteries provide 70%of the vascular supply of the anterior segment.A significant interruption of the vascular flow of these arteries increases the risk for anterior ischemia.Although the frequency of this special condition is low after strabismus surgery(1:13 000)[1],its effects may involve substantial visual problems[2].We report the successful outcome of a new surgical approach for strabismus management in a case of high risk for anterior ischemia.Specifically,we show the correction of the horizontal ocular deviation by means of an adjustable muscle

The robot-assisted ureteral reconstruction in adult:A narrative review on the surgical techniques and contemporary outcomes

Despite the rapid increase in the use of robotic surgery in urology,the majority of ureteric reconstruction procedures are still performed using laparoscopic or open approaches.This is primarily due to uncertainty regarding the advantages of robotic approaches over conventional ones,and the unique difficulty in identifying the specific area of interest due to the lack of tactile feedback from the current robotic systems.However,with the potential benefits of minimal invasiveness,several pioneering reports have been published on robotic surgery in urology.By reviewing the literature on this topic,we aimed to summarize the techniques,considerations,and consistent findings regarding robotic ureteral reconstruction in adults.Robotic applications for ureteral surgery have been primarily reported for pediatric urology,especially in the context of relieving a congenital obstruction in the ureteral pelvic junction.However,contemporary studies have also consistently demonstrated that robotic surgery could be a reliable option for malignant,iatrogenic,and traumatic conditions,which generally occur in adult patients.Nevertheless,the lack of comparative studies on heterogeneous hosts and disease conditions make it difficult to determine the benefit of the robotic approach over the conventional approach in the general population;thus,qualified prospective trials are needed for wider acceptance.However,contemporary reports have demonstrated that the robotic approach could be an alternative option for ureteral construction,even in the absence of haptic feedback,which can be compensated by various surgical techniques and enhanced three-dimensional visualization.

A novel surgical technique of internal limiting membrane peeling for high myopic foveoschisis:a wide range of whole piece consecutive peeling without preservation of epi-fovea

AIM:To demonstrate an improved surgical technique of whole piece consecutive internal limiting membrane(ILM) peeling without preservation of the epi-fovea to treat high myopic foveoschisis(MF).METHODS:A 23-gauge 3-port pars plana vitrectomy was performed on 16 patients with high MF.A parallel arc line along the vascular arcades was scraped out with a curved membrane scraper DSP.Next,an ILM forceps was used to catch hold of the incisal edge of the ILM flap,and the action of releasing and separating was subsequently taken toward the direction of the macular fovea.Next,the ILM forceps was used to grasp the released area,and the whole area coherent ILM peeling covering the macular fovea was implemented thereafter.Finally,the ILM was folded backwards and peeled off in the arc direction.RESULTS:At the final visit,the average central macular thickness decreased remarkably from 423.76±177.67 to 178.24±66.21 μm.The mean logarithm of the minimum angle of resolution best-corrected visual acuity of 1.37±0.59 was significantly alleviated to 0.74±0.59.CONCLUSION:The wide range of whole piece consecutive ILM peeling without preservation of the epifovea is proven to be effective and significantly reduced the occurrence of retinal tear and macular hole.

Minimally Invasive Surgical Technique in Double Aortic Arch with Distal Atretic Left-Side in Infant:From a Single-Surgeon Clinical Experience

Background:Double aortic arch(DAA)with distal left-sided aortic arch atresia(LAAA)can form complete vascular ring by ligamentum connection.We aimed to introduce an uncommon DAA-LAAA diagnosis and treatment by the minimally invasive surgical technique(MIST).Methods:We retrospectively reviewed 7 cases of DAA-LAAA that were treated from January 2017 to July 2021.All infant patients underwent surgical repair by minimally invasive surgical technique.Mean follow-up was 14.43 months(range,5–21 months).Results:There were seven patients with DAA-LAAA,including six males and one female.Median age was 19.29 months(range,9.0–29.0 months).Median weight was 11.30 kg(range,9.6–13.0 kg).Three patients were found severe tracheal compression by cardiac computed tomography angiography(cCTA).Six patients with isolated DAA-LAAA were performed operations through left subaxillary minithoracotomy,and one patient with ventricular septal defect(VSD)was performed operation concurrently under the cardiopulmonary bypass(CPB)through right subaxillary minithoracotomy.All patients had symptom improvement in the postoperative period and discharged successfully.Follow-up data showed good results in short-term.Conclusions:We introduce a new surgical pathway for DAA-LAAA treatment with good symptomatic relief in short-term.MIST is a safe,feasible and economical approach for infant patients.

Usefulness of Detailed Analysis with Operative Procedure of Total Laparoscopic Hysterectomy (TLH) Done a Single Surgeon, to Master the Surgical Technique of TLH and Gain Higher Proficiency

Objective: To analyze the relationship between the numbers of cases experienced and the operation time for a single surgeon aiming to master the TLH surgical technique. Material and Methods: Retrospective data analysis of women who underwent TLH for benign diseases between April, 2014 and March, 2016 was conducted by a single surgeon in a single hospital (Showa University of Fujigaoka Hospital). We divided the main procedures of the TLH operation into five sections, and measured the time required for each section. These cases were divided into three groups, group 1, 2, and 3. Results: There were 54 cases of TLH over two years for a single surgeon, and 21 cases that included essential operative procedures were divided into three groups of seven cases each. The average duration of the surgery (min.) was 178.3 ± 48.2 in the group 1, 128.3 ± 15.6 in the group 2, and 111.3 ± 15.9 in the group 3. A significant reduction in the required time was observed between group 1, 2, and 3 groups. As the number of cases increased, the operation time became statistically significantly shorter for every section except B and D. The skill growth rate was different at each section. Conclusion: For a single surgeon, as the number of surgical cases increased, we recognized the increased skill with the procedure in every section and the rate of skill growth differed for different sections. The difference of growth rate for each section implied that the number of operative cases required for a surgeon in each section was different.

The SUPER reporting guideline suggested for reporting of surgical technique

Background:Existing reporting guidelines pay insufficient attention to the detail and comprehensiveness reporting of surgical technique.The Surgical techniqUe rePorting chEcklist and standaRds(SUPER)aims to address this gap by defining reporting standards for surgical technique.The SUPER guideline intends to apply to articles that encompass surgical technique in any study design,surgical discipline,and stage of surgical innovation.Methods:Following the EQUATOR(Enhancing the QUAlity and Transparency Of health Research)Network approach,16 surgeons,journal editors,and methodologists reviewed existing reporting guidelines relating to surgical technique,reviewed papers from 15 top journals,and brainstormed to draft initial items for the SUPER.The initial items were revised through a three-round Delphi survey from 21 multidisciplinary Delphi panel experts from 13 countries and regions.The final SUPER items were formed after an online consensus meeting to resolve disagreements and a three-round wording refinement by all 16 SUPER working group members and five SUPER consultants.Results:The SUPER reporting guideline includes 22 items that are considered essential for good and informative surgical technique reporting.The items are divided into six sections:background,rationale,and objectives(items 1 to 5);preoperative preparations and requirements(items 6 to 9);surgical technique details(items 10 to 15);postoperative considerations and tasks(items 16 to 19);summary and prospect(items 20 and 21);and other information(item 22).Conclusions:The SUPER reporting guideline has the potential to guide detailed,comprehensive,and transparent surgical technique reporting for surgeons.It may also assist journal editors,peer reviewers,systematic reviewers,and guideline developers in the evaluation of surgical technique papers and help practitioners to better understand and reproduce surgical technique.

Robot-assisted adrenalectomy:Step-by-step technique and surgical outcomes at a high-volume robotic center

Objective In the last years,robotic surgery was introduced in several different settings with good perioperative results.However,its role in the management of adrenal masses is still debated.In order to provide a contribution to this field,we described our step-by-step technique for robotic adrenalectomy(RA)and related modifications according to the type of adrenal mass treated.Methods We retrospectively analyzed 27 consecutive patients who underwent RA at Onze-Lieve-Vrouw hospital(Aalst,Belgium)between January 2009 and October 2022.Demographic,intra-and post-operative,and pathological data were retrieved from our prospectively maintained institutional database.Continuous variables are summarized as median and interquartile range(IQR).Categorical variables are reported as frequencies(percentages).Results Twenty-seven patients underwent RA were included in the study.Median age,body mass index,and Charlson's comorbidity index were 61(IQR:49-71)years,26(IQR:24-29)kg/m^(2),and 2(IQR:0-3),respectively,and 16(59.3%)patients were male.Median tumor size at computed tomography scan was 6.0(IQR:3.5-8.0)cm.Median operative time and blood loss were 105(IQR:82-120)min and 175(IQR:94-250)mL,respectively.No intraoperative complications were recorded.Overall postoperative complications rate was 11.1%,with a postoperative transfusion rate of 3.7%.A total of 10(37.0%)patients harbored malignant adrenal masses.Among them,3(11.1%)had adrenocortical carcinoma,6(22.2%)secondary metastasis,and 1(3.7%)malignant pheochromocytoma on final pathological exam.Only 1(10.0%)patient had positive surgical margins.Conclusion We described our step-by-step technique for RA,which can be safely performed even in case of high challenging settings as malignant tumors,pheochromocytoma,and large masses.The standardization of perioperative protocol should be encouraged to maximize the outcomes of this complex surgical procedure.

More accurate reporting of surgical techniques would be SUPER

Surgical education entails learning to care for patients in and out of the operating theater.Clinically,this encompasses everything from the preoperative work-up to managing potential postoperative complications.In the operating room,surgical technique includes common,widely applicable skills,like how to square a knot,but also the more nuanced anatomical considerations of each operation,intra-operative decision-making,and ways to adapt when faced with the unexpected.Historically,surgical technique was taught through the apprenticeship model with knowledge passed down from attending to trainee and through textbooks written by surgical masters.This mode of learning/teaching is still the enduring structure of most residency programs.

Transsphenoidal approach to pituitary adenoma： surgical technique of the Peking Union Medical College Hospital

Hydromassage of macular hole edges for large and persistent full-thickness macular holes

●AIM:To introduce the macular hole(MH)hydromassage technique as a potentially beneficial approach for the treatment of large or persistent MH.●METHODS:This retrospective observational case series comprised 16 consecutive patients(17 eyes)diagnosed with MH.Inclusion criteria involved a hole aperture diameter larger than 600μm or the presence of an unclosed MH larger than 600μm following the previous vitrectomy.Standard MH repair procedures were administered in all cases,involving the manipulation and aspiration of the hole margin through the application of water flow with a soft-tip flute needle.A comprehensive assessment was conducted for each case before and after surgery,and optical coherence tomography(OCT)images were captured at every follow-up point.●RESULTS:The mean preoperative aperture diameter was 747±156μm(range 611-1180μm),with a mean base diameter of 1390±435μm(range 578-2220μm).Following surgery,all cases achieved complete anatomical closure of MH,with 13 cases(76.5%)exhibiting type 1 closure and 4 cases(23.5%)demonstrating type 2 closure.No significant differences were observed in the preoperative OCT variables between the two closure types.Eyes with type 1 closure showed a significantly improved visual acuity(0.70±0.10,range 0.50-0.80)compared to those with type 2 closure(0.90±0.12,range 0.80-1.00,P=0.014).●CONCLUSION:The MH hydromassage technique demonstrates promising results,achieving acceptable closure rates in cases of large or persistent MH.This technique may serve as an effective adjunctive maneuver during challenging MH surgery.

Direct anterior compared to posterior approach for hip hemiarthroplasty following femoral neck fractures

The differences in complication rates between the direct anterior and posterior approaches for hemiarthroplasty in elderly patients with femoral neck fractures are not yet fully understood.Dislocation,a severe complication associated with increased mortality and often requiring additional surgery,may occur less frequently with the direct anterior approach compared to the posterior approach.Careful consideration of patient demographics is essential when planning the surgical approach.Future research in this area should focus on robust randomized controlled trials involving elderly patients recovering from femoral neck fractures.

Dual mobility in primary total hip arthroplasty:A temptation from the devil or a blessing from above

Dual mobility(DM)bearings have gained significant attention in the field of total hip arthroplasty(THA)as a valid treatment option in cases of revision for instability after THA whereas its use in primary THA is still a matter of debate.This manuscript explores the pathology,incidence,diagnosis,treatment options,prognosis,ongoing studies in the literature,and future perspectives related to the use of DM bearings employed in primary THA.DM bearings are primarily designed to address one of the major concerns in THA:Instability of the prosthetic hip.Instability is both for the surgeon and the patient a devastating postoperative complication,leading to significant pain and subsequent apprehension by the patient and may require revision surgeries.The use of DM implants poses the worry of wear-related complications,such as accelerated polyethylene wear and osteolysis,which also pose challenges to long-term implant survival.This technique has seen a steady rise in recent years,with multiple studies reporting favorable outcomes.The incidence of their utilization varies among institutions and surgeons,reflecting differing preferences and patient populations.The diagnosis of instability and wear-related complications in THA often involves clinical assessment,imaging modalities such as X-rays,computed tomography scans,and sometimes advanced imaging techniques like magnetic resonance imaging.DM bearings can be considered as an option when patients present neurologic pathologies such as Parkinson's disease or recurrent dislocations after THA.DM bearings provide an additional articulation point within the implant,facilitating a greater range of motion and inherent stability.This design allows for reduced risk of dislocation and improved functional outcomes.Various implant manufacturers offer different designs and sizes of DM bearings to suit individual patient needs.Current literature suggests that the use of DM bearings in primary THA has demonstrated promising outcomes in terms of enhanced stability,reduced dislocation rates,and improved patient satisfaction.However,long-term studies with larger patient cohorts are necessary to establish the durability and longevity of these implants.Several ongoing studies are investigating the role of DM bearings in primary THA.These studies focus on evaluating longterm implant survivorship,assessing wear patterns,analyzing patient-reported outcomes,and comparing the effectiveness of DM bearings with traditional THA designs.The future of DM bearings in primary THA holds potential for further advancements.Research efforts are aimed at refining implant materials,optimizing designs,and studying the influence of surgical techniques on implant performance.Additionally,continued investigation into the long-term outcomes and cost-effectiveness of DM bearings will play a crucial role in shaping their future use.While further research is warranted,the current evidence supports their potential as a beneficial solution in improving surgical outcomes and patient satisfaction.

Modified techniques for adult-to-adult living donor liver transplantation

BACKGROUND: Because of critical organ shortage, transplant professionals have utilized living donor liver transplantation (LDLT) in recent years. We summarized our experience in adult-to-adult LDLT with grafts of right liver lobe by a modified technique. METHODS: From January 2002 to August 2005, 24 adult patients underwent living donor liver transplantation with grafts of the right liver lobe at West China Hospital, Sichuan University, China. Twenty-two patients underwent modi-Bed procedures designed to improve the reconstruction of the right hepatic vein and the tributaries of the middle hepatic vein by interposing a great saphenous vein ( GSV) graft and the anastomosis of the hepatic arteries and bile ducts. RESULTS: No severe complications and death occurred in all donors. In the first 2 patients, (patients 1 and 2), operative procedure was not modified. One patient suffered from 'small-for-size syndrome' and the other died of sepsis with progressive deterioration of graft function. In the rest 22 patients (patients 3 to 24), however, the procedure of venous reconstruction was modified, and better results were obtained. Complications occurred in 7 recipients including acute rejection (2 patients), hepatic artery thrombosis (1), bile leakage (1), intestinal bleeding (1), left sub-phrenic abscess (1), and pulmonary infection (1). One patient with pulmonary infection died of multiple organ failure (MOF). The 22 patients underwent direct anastomosis of the right hepatic vein to the inferior vena cava (IVC), 9 direct anastomosis plus the reconstruction of the right inferior hepatic vein, and 10 direct anastomosis plus the reconstruction of the tributaries of the middle hepatic vein by in-terpos-ing a GSV graft to provide sufficient venous outflow. Trifurcation of the portal vein was met in 3 patients. Venoplasty or separate anastomosis was performed. The ratio of graft to recipient body weight ranged from 0.72% to 1.17%. Among these patients, 19 had the ratio <1.0% and 4 <0.8%, and the ratio of graft weight to recipient standard liver volume was between 31.86% and 62.48%. Among these patients, 10 had the ratio <50% and 2 <40%. No 'small-for-size syndrome' occurred in the 22 recipients who were subjected to modified procedures. CONCLUSIONS: With the modified surgical techniques for the reconstruction of the hepatic vein to obtain an adequate outflow and provide a sufficient functioning liver mass, living donor liver graft in adults using the right lobe can be safe to prevent the 'small-for-size syndrome'.

Surgical treatment of Peyronie＇s disease： choosing the best approach to improve patient satisfaction

Aim： To discuss important points on medical history, preoperative evaluation, real expectations, and selection of the appropriate surgical procedure to improve patient satisfaction after surgical procedures for Peyronie＇s disease. Methods： Recent advances in approaches to Peyronie＇s disease are discussed based on the literature and personal experiences. Issues concerning surgical indication, patient selection, surgical techniques, and grafting are discussed. Lengthening procedures on the convex side of the penile curvature by means of grafting offer the best possible gain from a reconstruction standpoint. Penile rectification and rigidity are required to achieve a completely functional penis. Most patients experience associated erectile dysfunction （ED）, and penile straightening alone may not be enough to restore complete function. Twenty-five patients were submitted to total penile reconstruction on length and girth with concomitant penile prosthesis implant. The maximum length restoration was possible and limited by the length of the dissected neurovascular bundle. The mean age was 55.4 years （32-69 years） and the mean angle of curvature 74.2± 22.4° （0-100°）. Pericardial grafting was used to cover the defect. The mean follow-up time was 11.2 ± 5.9 months （3-22 months）. Results： Mean functional penile length gain was 3.40 ＋ 0.73 cm （2-5 cm）. Penile prosthesis maintained the penis straight. No infections occurred. Sexual intercourse was restored in all patients and all reported recovered self-esteem. Conclusion： Improving patient satisfaction with the surgical treatment includes proper preoperative evaluation on stable disease, penile shortening, vascular and erectile status, patient decision and selection as well as extensive discussion on surgical technique for restoring functional penis （length and rigidity）. Length and girth restoration is very important for self-esteem and patient satisfaction.
