Comparison between Open Epididymal Cystectomy and Minimal Resection of Epididymal Cysts Using a Scrotoscope: A Clinical Trial for the Evaluation of a New Surgical Technique

Safety and Feasibility of Electro-Vaporization of Ligamentum Teres Hepatis in Totally Laparoscopic Gastrectomy

Introduction: The ligamentum teres hepatis may block the field of vision during totally laparoscopic gastrectomy (TLG), especially in patients with obesity. Aim: We used electrocautery to increase the visual field of TLG by shrinking the ligamentum teres hepatis. This procedure is termed electro-vaporization of the ligamentum teres hepatis (EVLTH). Methods: Patients with body mass index (BMI) ≥24 who underwent total laparoscopic distal gastrectomy (TLDG) or total laparoscopic total gastrectomy (TLTG) between January 2020 and December 2023 were retrospectively enrolled. According to the scope of gastrectomy and whether the patients underwent EVLTH, the patients were divided into the TLDG-EVLTH, TLDG-NEVLTH, TLTG-EVLTH, and TLTG-NEVLTH groups. The clinical characteristics, surgical outcomes, and pathological features were compared between the TLDG-EVLTH and TLDG-NEVLTH groups and the TLTG-EVLTH and TLTG-NEVLTH groups. Results: This study included 65 patients who underwent TLDG (EVLTH: NEVLTH = 29:36) and 32 patients who underwent TLTG (EVLTH:NEVLTH = 15:17). There were no significant differences in clinical characteristics, surgical outcomes, and pathological features between the TLDG-EVLTH and TLDG-NEVLTH groups. However, the operation time in the TLTG-EVLTH group was significantly shorter than that in the TLTG-NEVLTH group, and the difference was statistically significant, although differences in other data were not statistically significant. Conclusions: EVLTH is a simple and safe procedure that reduces the operation time of TLTG in patients who are overweight and enhances the field of vision of TLG.

The Application of Scrotoscope-Assisted Minimally Invasive Excision for Epididymal Mass: An Initial Report

Background

To compare the middle-term efficacy and safety results between scrotoscope-assisted (SA) minimally invasive excision and traditional open excision (OE) for the treatment of epididymal mass.

Methods

A total of 253 males with surgery excision of epididymal mass from 2012 to 2018 were included in this retrospective study. Patients were divided into two groups: the traditional OE group and the SA group. Patient demographics and intraoperative and postoperative outcomes were obtained and compared between these two groups.

Results

About 174 patients (68.8%) underwent SA, and the other 79 (31.2%) underwent OE. Demographic data were similar between the two groups. Compared with OE surgery, SA could significantly shorten the operating time (19.4 ± 4.1 vs. 53.8 ± 12.9 min), reduce blood loss (5.3 ± 1.5 vs. 21.3 ± 5.6 ml), and downsize the operative incision (1.5 ± 0.3 vs. 4.5 ± 0.8 cm). Additionally, postoperative complications were significantly less occurred in the SA group than those in OE (15.5% vs. 21.5%), in particular scrotal hematoma (1.7% vs. 12.7%) and incision discomfort (2.8% vs. 6.3%). Patients in the SA group had a significantly higher overall satisfaction score (94.8 ± 3.7 vs. 91.7 ± 4.9) and a significantly shorter length of hospital stay (4.1 ± 0.9 vs. 5.0 ± 1.5 days) than those in the OE group. No postoperative testicular atrophy occurred in the SA group.

Conclusion

SA is emerging as a novel and effective option with promising perspectives for epididymal mass therapy.

Side predilection in congenital anomalies of the kidney, urinary and genital tracts

BACKGROUND

There appear to be various patterns of sidedness with relation to the common urogenital malformations observed in pediatric urology. The objective of this statistical review was to synthesize this data and to assess if these patterns are significant.

MATERIALS AND METHODS

Eighteen urogenital conditions were investigated and for each condition the five largest studies that noted laterality were included. The sidedness of each condition was then analysed for statistical significance.

RESULTS

Three conditions had a statistically significant higher proportion on the right side: palpable undescended testis (63%, p = 0.0002), inguinal hernia (59%, p = 0.0001) and hydrocele (60%, p = 0.003). Three conditions were significantly more common on the left side: impalpable undescended testis (59%, p = 0.0008), renal agenesis (54%, p = 0.02) and vesico-ureteric junction obstruction (71%, p < 0.0001) while both pelvi-ureteric junction obstruction (62%, p = 0.09) and absent vas deferens (61%, p = 0.11) were trending towards significance.

CONCLUSIONS

Various urogenital malformations display a predilection for one side. Proximal malformations tend to be more frequently seen on the left side, where as inguinoscrotal malformations are more frequently observed on the right. There is an increasing body of literature regarding aetiological factors for these conditions. However, our current understanding of the pathophysiology of these conditions does not completely explain this pattern of observation.

Scrotoscopy and traditional open surgery shows a high degree of consistency in the diagnosis of testicular torsion: An initial report

Traditional open surgery (OS) is usually necessary when testicular torsion (TT) cannot be excluded by scrotal ultrasound. Scrotoscopy has been used as a minimally invasive technique to diagnose or treat scrotal diseases, and it may also play a role in diagnosing TT.A retrospective analysis was performed for patients with TT to evaluate the consistency of scrotoscopy and OS in the diagnosis of TT. In the cases where preoperational Color Doppler ultrasonography was performed, scrotoscopy, open surgery, and confirmed TT were included for future analysis.A total of 43 patients were studied. Twisted testes were retained in 11 cases (25.59%), and the remaining 32 patients (74.41%) underwent orchiectomy. There were significant differences in the diagnostic value between the grading of scrotoscopy and ultrasound, as well as between ultrasound grading and blood supply grading (BSG) (both P < .05). However, no significant difference was observed between the grading of scrotoscopy and BSG in traditional OS (P > .05), but a high degree of consistency existed between scrotoscopy grading and BSG in traditional OS (Kappa = 0.733, P ≤ .001).Our limited data indicate that the diagnosis of testicular torsion by scrotoscopy is highly consistent with that of traditional surgical exploration. Therefore, further studies are necessary to confirm its application value in the future. Scrotoscopy may have potential application value for the patients whom testicular torsion are insufficiently diagnosed but cannot be excluded.

Scrotoscopy exploration of testicular rupture: A pilot study

To examine whether scrotoscopy could be used to diagnose testicular rupture (TR) with accuracy.This retrospective study included all patients receiving scrotoscopy followed by immediate open exploration (OE) for suspected TR at two Chinese tertiary care centers between March 2014 and March 2018.Fifteen patients suspected of having TR were included. TR was considered in 8 patients (8/15) via emergency scrotal ultrasound (ESU) examination. Of these 8 patients, 6 cases as well as 3 other cases, a total of 9 cases (9/15) were confirmed TR by scrotoscopy and OE; the remaining 6 patients (6/15) were found disease free. The presence/absence of TR was identified correctly with scrotoscopy in all 15 cases. The rupture size of the testicular tunica albuginea (TTA) varied from 0.5 to 2 cm. Only 3 cases (3/15) had scrotal wall edema and all quickly recovered. The testis was normal in size and blood flow at 6-month follow-up visit.Scrotoscopy accurately diagnoses TR, and may avoid unnecessary OE, especially for the patients confirmed free of disease.

Individualized minimally invasive treatment for adult testicular hydrocele: A pilot study

BACKGROUND

Hydrocelectomy is the gold standard for the treatment of hydrocele, but it often causes complications after surgery, including hematoma, infection, persistent swelling, hydrocele recurrence, and chronic pain. In recent years, several methods for minimally invasive treatment of hydrocele have been introduced, but they all have limitations. Herein, we introduce a new method of individualized minimally invasive treatment for hydrocele.

AIM

To present a new method for the treatment of adult testicular hydrocele.

METHODS

Fifty-two adult patients with idiopathic testicular hydrocele were included. The key point of this procedure was that the scope of the resection of the sheath of the tunica vaginalis was determined according to the maximum diameter (d) of the effusion measured by ultrasound and the maximum diameter of the portion of the sheath pulled out of the scrotum was approximately πd/2. The surgical procedure consisted of a 2-cm incision in the anterior wall of the scrotum, drainage of the effusion, and dissection of part of the sheath of the tunica vaginalis. After the sheath was peeled away to the predetermined target extent, the pulled-out sheath was removed. The intraoperative findings and postoperative complications were analyzed.

RESULTS

All patients were successfully treated with a median operation time of 18 min. The median maximum diameter of the effusion on ultrasound was 3.5 cm, and the median maximum diameter of the resected sheath was 5.5 cm. Complications occurred in four (7.7%) patients: two (3.8%) cases of mild scrotal edema, one (1.9%) case of scrotal hematoma, and one (1.9%) case of wound infection. All of the complications were grade I-II. Recurrent hydrocele, chronic scrotal pain, and testicular atrophy were not observed during a median follow-up of 12 mo.

CONCLUSION

We report a new technique for individualized treatment of testicular hydrocele, which is quantitative and minimally invasive and yields good outcomes. Further study is warranted to verify its potential value in clinical practice.

How to Treat Chronic Idiopathic Testicular Pain? Scrotoscopy with a Novel Percutaneous Endoscopy Equipment

Background

Management of chronic idiopathic testicular pain may be difficult because of problems identifying the causes. We evaluated “AUTOKLAV”, a novel endourological nephrolithotomy device to diagnose and treat chronic idiopathic testicular pain.

Methods

We divided 103 patients to either scrotoscopy group (SG, n = 64) or open exploration group (OEG, n = 39) between September 2014 and March 2017 at Zhongnan Hospital. Perioperative information, like operating time, length of incision, and wound infections, was carefully recorded during in hospital. Follow-up data, like pain scores improvement, satisfaction with penis appearance, and adverse event, were collected at one month postoperatively.

Results

Finally, both the operating time and length of incision showed better performance for SG (43.6 ± 4.7 versus 51.5 ± 9.0 min; 0.7 ± 0.2 versus 4.1 ± 0.8 cm; both P <0.01). Though the pain improvement had no significant differences between the two groups (2.92 ± 0.99 and 2.14 ± 1.02, p>0.05), SG showed obvious advantages in incidence of wound infections and satisfaction with wound/scrotum appearance (0% versus 2.9%; 96.4% versus 85.3%, both P<0.05).

Conclusions

In conclusion, scrotoscopy using the novel AUTOKLAV device is feasible, has an acceptable complication rate, and can be effective and safe in men with idiopathic chronic testicular pain. Etiologically, secondary inflammatory changes caused by the complete or incomplete torsion of testicular or epididymis appendices or by the existence of stones in the tunica sac might be responsible for the pain.

Microsurgical Epididymal Cystectomy does not Impact Upon Sperm Count, Motility or Morphology and is a Safe and Effective Treatment for Epididymal Cystic Lesions (ECLs) in Young Men With Fertility Requirements

OBJECTIVE

To assess the therapeutic efficacy and safety of microsurgical epididymal cystectomy for the treatment of epididymal cystic lesions in young men with fertility requirements and the impact of this surgery upon sperm quality and epididymal function.

MATERIALS AND METHODS

We prospectively evaluated the therapeutic outcomes, complications, safety and efficacy of microsurgical epididymal cystectomy and the impact of microsurgery upon sperm parameters. All patients were followed-up 3, 6 and 12 months after surgery to investigate sperm count, motility, morphology, neutral α-glucosidase, improvement of symptoms, recurrence, and complications.

RESULTS

Palpated cyst pain was evident in 32 out of 51 patients. Pathologists identified 29 spermatoceles and 22 epididymal cysts. Mean operation time was 39.27 ± 5.98 minutes, and the mean length of postoperative hospital stay was 2.02 ± 0.35 days. After surgery, scrotal pain disappeared in 80.4% of patients (41/51). A significantly higher rate of pain disappearance was observed in patients with palpated pain than those without palpated pain. Insignificant difference was seen in terms of sperm count, motility, sperm morphology or neutral α-glucosidase between preoperation and postoperation at 1-year follow-up. Sperm count and NGA in patients with an epididymal cystic lesions > 2.5 cm were significantly increased after surgery. The rate of complications was 7.3%. No cyst recurrence was observed during follow-up.

CONCLUSION

Microsurgical epididymal cystectomy does not impact upon sperm count, motility, morphology, or epididymal function and is a safe and effective surgical modality for young men with fertility requirements. Local palpated pain on the epididymal cyst is recommended as an optional surgical indication.
