OBJECTIVE: To observe the clinical effect of needle cauterization on vitiligo with deficiency cold and blood stasis. METHODS: A total of 62 patients of vitiligo with deficiency cold and blood stasis were randomly divided into an observation group and a control group, 31 cases each group.On the basis of 308 nm excimer light irradiation combined with ironing with Chinese medicine, the control group was treated with tacrolimus ointment for external use, twice a day; the observation group was treated with needle cauterization at vitiligo spots, once a week.Both groups were treated for 10 weeks. Before and after treatment, the area of vitiligo spot, TCM syndrome score, serum levels of inflammatory indexes (interleukin[IL]-6 and IL-17) were observed in the two groups, and the clinical effect was evaluated. RESULTS: After treatment, the areas of vitiligo spot, TCM syndrome scores and serum levels of IL-6, IL-17 were decreased compared with those before treatment in both groups (P<0.05), and the above indexes in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 93.5% (29/31), which was higher than 77.4% (24/31) in the control group (P<0.05). CONCLUSION Needle cauterization could reduce the areas of vitiligo spot in patients of vitiligo with deficiency cold and blood stasis, improve the clinical symptoms, its mechanism may be related to the reduction of serum levels of inflammatory indexes.

We aimed to assess the occlusive effectiveness of open-ended vasectomy with mucosal cautery and fascial interposition and to determine the factors associated with occlusion failure. We studied all vasectomies performed between September 1, 2020, and August 31, 2021, by four vasectomy surgeons from Quebec City, Quebec, Canada. Sociodemographic and clinical characteristics were extracted from the electronic medical records. Occlusive effectiveness was assessed in all men with at least one postvasectomy semen analysis (PVSA). The effectiveness criteria were adapted from those of the American Urological Association (AUA) vasectomy guideline. Among the 4000 eligible vasectomies, 2242 (56.1%) were followed by at least one PVSA, with 99 (4.4%) requiring more than one PVSA. Occlusive effectiveness was achieved in 2233 vasectomies (99.6%; 95% confidence interval [CI]: 99.3%-99.8%), with 2199 (98.1%) and 34 (1.5%) classified as confirmed and probable success, respectively. The final status of the three vasectomies (0.1%) was indeterminate. Occlusive failure was observed in six vasectomies (0.3%; 95% CI: 0.1%-0.6%). The four surgeons had a similar risk of failure. The only significant factor associated with failure was the difficulty in performing the vas occlusion reported by the surgeon (7.4% [2/27] vs 0.2% [4/2212]; relative risk = 41.0; 95% CI: 7.8-214.2). The high occlusive effectiveness observed in our study validates AUA recommendations, supporting the use of this technique. Difficulty in occlusion of the vas deferens, as reported by surgeons, was the only factor associated with vasectomy failure. This finding highlights the need for PVSA in such cases.

Objective:To explore the diagnosis and minimal invasive treatment of neonatal pyriform sinus fistula. Methods:A retrospective analysis was conducted on the clinical data of newborns diagnosed with pyriform sinus fistula in the Children's Hospital, Zhejiang University School of Medicine from January 2016 to December 2023, including the diagnostic process and treatment methods. Results:There were 8 children, 2 males and 6 females, with 7 cases on the left side and 1 case on the right side. Six cases revealed a lump in the fetal neck during prenatal examination, and two cases were found to have a neck mass after birth. All cases presented with varying degrees of respiratory disorders. After admission, all patients underwent neck ultrasound and contrast-enhanced CT examination. Neck ultrasound showed cystic masses, with 3 of the cysts accompanied by septa, and an air-fluid level was observed in the cysts in 6 cases from contrast-enhanced CT. All patients underwent ultrasound-guided neck mass puncture and/or tube placement combined with endoscopic electrocauterization. The cystic fluid was found to be yellow and thin, with no signs of infection. The surgical operations were uneventful, and the follow-up time ranged from 12 to 72 months postoperatively. There were no complications such as hoarseness, and no recurrence cases were reported. Conclusion:Neonatal pyriform sinus fistula is often characterized by a large cystic mass in the neck combined with respiratory depression. The presence of an air-fluid level in the cyst from contrast-enhanced CT can be considered an important basis for early diagnosis of pyriform sinus fistula. Ultrasound-guided puncture combined with endoscopic electrocauterization is minimally invasive and safe, making it a suitable minimal invasive treatment for neonatal pyriform sinus fistula.

Objective: To compare the efficacy, advantages and disadvantages of endoscopic CO₂ laser cauterization (ECLC) and open neck surgery in the treatment of congenital pyriform sinus fistula (CPSF). Methods: From September 2014 to March 2017, 80 cases with confirmed diagnosis of CPSF received initial treatment at Guangdong Provincial People's Hospital were prospectively analyzed, including 34 males and 46 females, aged 18 to 672 (194.17±141.18) months. They were consecutively divided into endoscopic group and open-surgery group, with 40 cases in each group. Both groups of patients received surgical treatment under general anesthesia. The endoscopic group was treated by endoscopic CO₂ laser cauterization, and the open-surgery group underwent the following surgery: first, we performed suspension laryngoscopy examination to confirm the presence of fistula in the bottom of the piriform fossa, then open-neck resection of congenital piriform sinus fistula with recurrent laryngeal nerve and/or lateral branch of superior laryngeal nerve anatomy plus partial thyroidectomy were performed. The data between the two groups were compared, including the operative time, intraoperative blood loss, postoperative pain, average length of stay, neck cosmetic scores, complications and cure rates. All patients were followed up in outpatient clinics. Statistical analysis was performed using SPSS 20.0 software. P<0.05 indicates that the difference is statistically significant. Results: All patients were successfully completed the operation. The operative time, intraoperative blood loss, postoperative pain and average length of hospital stay in the endoscopic group were significantly less than those in the open group [(27.4±5.5) min to (105.8±52.5) min, (0.6±0.5) ml to (33.6±41.5) ml, (1.7±0.9) points to (4.6±0.7) points, (5.9±2.9)d to(8.9±3.3)d, t values were-9.400, -5.031, -16.199, -4.293, P values were all<0.01]; The neck cosmetic score in the endoscopy group was significantly greater than that of the open group [(9.9±0.4) against (5.8±0.9) points, t=25.847, P<0.01]. Compared with the open group (15.0%, 6/40), the complication rate of the endoscopic group (7.5%, 3/40) was not statistically significant (χ²=0.50, P>0.05). Three months after the first treatment, the cure rate in the endoscopic group (82.5%, 33/40) was significantly lower than that in the open-neck group (100.0%, 40/40), χ²=5.64, P<0.05. The follow-up time was 12 months after the last treatment. Eighty cases were followed up and none was lost to follow-up. During the follow-up period, the cure rate of the endoscopy group (97.5%, 39/40) was compared with that of the open group (100.0%, 40/40), and the difference was not statistically significant. Conclusions: In the treatment of CPSF, the two-surgical method each has their advantages. Compared with open-neck surgery, ECLC is simpler, repeatable. ECLC has shorter time in operation and hospital stay, less complications, and less postoperative pain and more precise cosmetic results. It could be preferred for the initial treatment of CPSF and relapsed cases after cauterization. But subject to relatively low cure rate of one-time cauterization and uncertain long-term efficacy, it cannot completely replace the open-neck surgery at present.

Objective: To investigate the advantages and disadvantages of point electro-cauterization (PEC) and holmium laser cauterization (HLC) in the treatment of post-ejaculation hematuria. METHODS: From January 2015 to December 2018, 73 patients with post-ejaculation hematuria, aged 24－63 (36.8 ± 4.2) years, underwent PEC (n = 35) or HLC (n = 38) after failure to respond to 3 months of conservative treatment. We compared the hospital days, total hospitalization expenses, maximum urinary flow rate (Qmax), average urinary flow rate (Qavg), Hamilton Anxiety Rating Scale (HAMA) score, postoperative duration of hematuria, and recurrence rate at 3 and 6 months after surgery. RESULTS: All the patients experienced first ejaculation but no post-ejaculation hematuria at 1 month after operation. The recurrence rates were lower in the PEC than in the HLC group at 3 months (5.71% vs 2.63%, P > 0.05) and 6 months postoperatively (8.57% vs 5.26%, P > 0.05). Compared with the baseline, the Qmax was decreased from (18.56 ± 2.53) ml/s to (13.68 ± 3.31) ml/s (P < 0.05) and the Qavg from (14.35 ± 2.26) ml/s to (9.69±1.84) ml/s in the PEC group at 1 month after surgery (P < 0.01), but neither showed any statistically significant difference in the HLC group. Mild to moderate anxiety was prevalent in the patients preoperatively, particularly in those without job or regular income and those with a long disease course or frequent onset, the severity of which was not correlated with age, education or marital status. The HAMA score was decreased from18.65 ± 4.33 before to 12.35 ± 3.63 after surgery in the PEC group (P < 0.01), and from 16.88 ± 2.11 to 6.87 ± 4.36 in the HLC group (P < 0.01). The mean hospital stay was significantly longer in the former than in the latter group (［5.2 + 1.3］ vs ［3.4 ± 0.5］ d, P < 0.01), while the total cost markedly lower (［6.35 ± 1.20］ vs ［12.72 ± 2.15］ thousand RMB ¥, P < 0.05). CONCLUSIONS Both PEC and HLC are safe and effective for the treatment of post-ejaculation hematuria, with no significant difference in the recurrence rate at 3 and 6 months after operation, but their long-term effect needs further follow-up studies. PEC may increase the risk of negative outcomes of the postoperative urinary flow rate, while HLC has the advantages of better relieving the patient's anxiety, sooner discharge from hospital and earlier recovery from postoperative hematuria, though with a higher total cost than the former.

A Le Fort I osteotomy is a common procedure for correcting dental and facial deformities in orthognathic surgery. In rare cases, a delayed hemorrhage can occur as early as several hours or up to 12 weeks, postoperatively. The most frequently involved blood vessels in a delayed hemorrhage are the descending palatine artery, the internal maxillary artery, and the pterygoid venous plexus of veins. Intraoral bleeding accompanied by severe epistaxis in these cases makes it difficult to locate the precise bleeding focus. Eventual uncontrolled bleeding would require Merocel packing or surgical intervention. In general, a severe late postoperative hemorrhage is most effectively managed by angiography and embolization. Herein we describe a delayed hemorrhage case in which the cause was not evident on angiography. We were able to detect the bleeding point through an endoscopic nasal approach and treat it using direct cauterization.

The characteristics of extra-nasopharyngeal angiofibromas tend to be different from angiofibromas of the nasopharynx according to patient gender, patient age, prevalence, affected site, pathogenesis, and clinical and epidemiological features. We report a case of an extra-nasopharyngeal angiofibroma in a 28-year-old man referred to the ENT Clinic for right-sided epistaxis, airflow impairment and nasal swelling. The right nostril was completely occluded works by a reddish-yellow mass that bled easily. The computed tomography scan revealed an “inhomogeneous solid lesion in the nasal fossa”. With the patient under general anesthesia, the formation in the anterior portion of the right side of the nasal septum was removed up to its vascular base. Although electrical cauterization efficiently controlled the bleeding, we abraded the sub-perichondral area to prevent further bleeding as well as recurrence. The histological exam report confirmed the diagnosis of angiofibroma. As in our case, epistaxis is commonly the presenting sign of angiofibroma. Yet its onset was peculiar, given that the bleeding started with a low impact trauma. The nasal swelling was also a relevant feature as well as the breathing impairment. Although uncommon, nasal septal angiofibromas should considered in patients with epistaxis.

OBJECTIVES: Small animal maxillofacial models, such as non-segmental critical size defects (CSDs) in the rabbit mandible, need to be standardized for use as preclinical models of bone regeneration to mimic clinical conditions such as maxillofacial trauma. The objective of this study is the establishment of a mechanically competent CSD model in the rabbit mandible to allow standardized evaluation of bone regeneration therapies. MATERIALS AND METHODS: Three sizes of bony defect were generated in the mandibular body of rabbit hemi-mandibles: 12 mm×5 mm, 12 mm×8 mm, and 15 mm×10 mm. The hemi-mandibles were tested to failure in 3-point flexure. The 12 mm×5 mm defect was then chosen for the defect size created in the mandibles of 26 rabbits with or without cautery of the defect margins and bone regeneration was assessed after 6 and 12 weeks. Regenerated bone density and volume were evaluated using radiography, micro-computed tomography, and histology. RESULTS: Flexural strength of the 12 mm×5 mm defect was similar to its contralateral; whereas the 12 mm×8 mm and 15 mm×10 mm groups carried significantly less load than their respective contralaterals (P<0.05). This demonstrated that the 12 mm×5 mm defect did not significantly compromise mandibular mechanical integrity. Significantly less (P<0.05) bone was regenerated at 6 weeks in cauterized defect margins compared to controls without cautery. After 12 weeks, the bone volume of the group with cautery increased to that of the control without cautery after 6 weeks. CONCLUSION: An empty defect size of 12 mm×5 mm in the rabbit mandibular model maintains sufficient mechanical stability to not require additional stabilization. However, this defect size allows for bone regeneration across the defect. Cautery of the defect only delays regeneration by 6 weeks suggesting that the performance of bone graft materials in mandibular defects of this size should be considered with caution.

A nasal hemangioma is a rare lesion that causes intranasal bleeding. When endoscopically removing an endonasal hemangioma, the minimization of bleeding is imperative to optimize visualization and decrease complications. Many methods can be used to decrease bleeding during endoscopic removal, including cautery and embolization. We treated one patient with a hemangioma arising from the mucosa of the right inferior turbinate, which was removed successfully using a minimally invasive endoscopic endonasal technique with radiofrequency coblation to minimize bleeding. Herein we report this case and review the literature.

Surgery remains the standard treatment for acute cholecystitis except in high-risk candidates where percutaneous transhepatic gallbladder drainage (PT-GBD), endoscopic transpapillary cystic duct stenting (ET-CDS), and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) are potential choices. PT-GBD is contraindicated in patients with coagulopathy or ascites and is not preferred by patients owing to aesthetic reasons. ET-CDS is successful only if the cystic duct can be visualized and cannulated. For 189 patients who underwent EUS-GBD via insertion of a lumen-apposing metal stent (LAMS), the composite technical success rate was 95.2%, which increased to 96.8% when LAMS was combined with co-axial self-expandable metal stent (SEMS). The composite clinical success rate was 96.7%. We observed a small risk of recurrent cholecystitis (5.1%), gastrointestinal bleeding (2.6%) and stent migration (1.1%). Cautery enhanced LAMS significantly decreases the stent deployment time compared to non-cautery enhanced LAMS. Prophylactic placement of a pigtail stent or SEMS through the LAMS avoids re-interventions, particularly in patients, where it is intended to remain in situ indefinitely. Limited evidence suggests that the efficacy of EUS-GBD via LAMS is comparable to that of PT-GBD with the former showing better results in postoperative pain, length of hospitalization, and need for antibiotics. EUS-GBD via LAMS is a safe and efficacious option when performed by experts.
