BACKGROUND AND OBJECTIVE

Foreign body (FB) ingestion is a common pediatric concern in the Philippines, but local studies on flexible endoscopic management are lacking. This study aimed to describe the clinical profile and outcomes of children referred for flexible endoscopic management and identify factors associated with poor outcomes.

METHODS

This retrospective cohort study included 145 patients aged

RESULTS

Most FB ingestions (96.55%) were accidental, with coins as the most common FB (56.55%). Patients were admitted an average of 40.42 hours post-ingestion and referred for endoscopy within 9.28 hours. Flexible endoscopy was performed in 44.83% of cases, with a 98.46% success rate and an average procedure time of 32.25 minutes. Spontaneous passage occurred in 50.34% of cases. Poor outcomes were linked to age 48 hours; OR: 15.43, p = 0.0181), and prolonged procedures (>30 minutes; OR: 12, p = 0.0318). Good outcomes were associated with unremarkable physical exams (OR: 0.078; p = 0.0018), early admission (CONCLUSION

Flexible endoscopy is effective and safe for FB extraction in children. Early admission and timely intervention significantly improve outcomes, while delays and prolonged procedures increase the risk of complications.

The emergence of sialoendoscopy has fundamentally altered and has played a huge role in the diagnosis and treatment of salivary gland diseases. However, nationwide, the number of oral and maxillofacial surgeons skilled in the use of sialoendoscopy is very small, which limits its further promotion and application. No standardized training program is currently available for sialoendoscopy in domestic stomatology colleges, and the content and assessment standards of relevant training needs further improvement. Based on relevant clinical and teaching experience, this paper emphasizes the important role of clinical application and skill training for sialoendoscopy, with the aim of promoting the popularization and development of sialoendoscopic therapy.

OBJECTIVE: To compare the clinical efficacy of unilateral biportal endoscopic discectomy(UBE) and percutaneous interlaminar endoscopic discectomy(PIED) in the treatment of highly migrated lumbar disc herniation (LDH). METHODS: A retrospective analysis was conducted on 43 patients with highly migrated LDH who underwent spinal endoscopic surgery between January 2022 and December 2023. In the UBE group 22 patients included 8 males and 14 females, aged 49 to 59 years old with a mean of (54.13±2.07) years old. In the PIED group 21 patients included 11 males and 10 females, aged 49 to 59 years old with a mean of (55.04±2.80) years old. Perioperative parameters including intraoperative blood loss, operative time, and fluoroscopic exposures were compared between groups. Clinical outcomes were assessed using the visual analogue scale (VAS) for pain, Oswestry disability index (ODI), and modified MacNab criteria. Complications during the perioperative period and follow-up were recorded. RESULTS: In the PIED group, there were 3 cases of nerve injury, 1 case of residual nucleus pulposus, and 1 case of dural injury. In the UBE group, there was 1 case of nerve injury and 1 case of cerebrospinal fluid leakage. No infections or major bleeding occurred in either group. All patients completed surgery and were followed up for at least 12 months. The UBE group had significantly more intraoperative blood loss (39.09±6.10) ml and more fluoroscopic exposures (6.45±0.26) than the PIED group (34.05±5.62) ml and (3.24±0.28) with significant difference (P<0.05). Preoperative VAS and ODI showed no significant differences between two groups (P>0.05). Both groups demonstrated significant improvements in VAS and ODI postoperatively (P<0.001). At the 3rd days postoperatively, the UBE group had a significantly lower leg pain VAS (2.27±0.20) than the PIED gruop(2.95±0.24) with significant difference (P<0.05), but no significant differences were observed at the first or 12th months (P>0.05). No significant differences in ODI were found between two groups during follow-up (P>0.05). At the 1st month postoperatively, according to modified MacNab criteria, 15 patients got excellent results, 4 good, and 2 fair in PIED group;and 18 patients got excellent results, 2 good, and 2 fair in UBE group, with no significant difference between two groups(P>0.05). CONCLUSION Both PIED and UBE are effective surgical methods for treating highly migrated LDH. Compared with PIED, UBE involves slightly longer operative time, more blood loss, and more fluoroscopic exposures, but carries a lower risk of nerve injury.

OBJECTIVE: To explore the clinical efficacy of conventional transforaminal endoscopic technique and I See transforaminal endoscopic technique in the treatment of recurrent L₅S₁ lumbar disc herniation with high iliac crest. METHODS: A total of 36 patients with recurrent L5S1 lumbar disc herniation with high iliac crest after posterior small-incision discectomy, admitted from May 2016 to May 2023, were selected. They were divided into the conventional transforaminal endoscopy group and the I See transforaminal endoscopy group according to the different transforaminal endoscopic techniques adopted, and all patients in both groups underwent lateral transforaminal spinal canal decompression and discectomy. There were 18 patients in the conventional transforaminal endoscopy group, including 11 males and 7 females, with an age of (52.24±6.68) years;the I See transforaminal endoscopy group also had 18 patients, including 12 males and 6 females, with an age of (50.75±7.79) years. The perioperative indicators (operation time, number of intraoperative radiographs, and length of hospital stay) were compared between two groups. The clinical efficacy was evaluated using the visual analogue scale(VAS) for pain, the Japanese Orthopaedic Association(JOA) low back pain score, and the modified MacNab criteria before and after surgery. RESULTS: All patients achieved gradeⅠincision healing, with no infection cases. The operation time of the I See group was (64.25±16.67) minutes, which was significantly shorter than that of the conventional transforaminal endoscopy group (89.11±17.24) minutes, and the difference was statistically significant(P<0.05). The number of intraoperative radiographs in the I See group was (5.20±2.29) times, which was significantly less than that in the conventional transforaminal endoscopy group(19.16±3.68) times, and the difference was statistically significant(P<0.05). The VAS and total JOA scores of both groups at the 3rd day, the 3rd month after surgery, and the last follow-up were significantly lower than those before surgery, with statistically significant differences(P<0.05);however, there were no statistically significant differences in VAS and total JOA scores between two groups at the 3rd day, the 3rd month after surgery, and the last follow-up (P>0.05). According to the modified MacNab criteria for efficacy evaluation:in the conventional transforaminal endoscopy group, 14 cases were excellent and 4 cases were good;in the I See transforaminal endoscopy group, 15 cases were excellent and 3 cases were good;there was no statistically significant difference in efficacy between two groups(Z=0.177, P=0.674). CONCLUSION Both transforaminal endoscopic techniques have good clinical effects in the treatment of recurrent L₅S₁ lumbar disc herniation with high iliac crest, resulting in significant improvement of postoperative symptoms, and they are safe, reliable, and minimally invasive surgical methods. Compared with the conventional transforaminal endoscopy, the I See transforaminal endoscopic technique has shorter operation time and fewer intraoperative radiographs, so it is generally the first choice.

OBJECTIVE: To investigate the early clinical efficacy, safety, and application value of one-hole split endoscopy (OSE)-assisted transforaminal lumbar interbody fusion(TLIF) in the treatment of lumbar degenerative diseases. METHODS: A retrospective analysis was conducted on 17 patients with lumbar degenerative diseases who underwent OSE-assisted TLIF between June 2023 and June 2024. There were 10 males and 7 females, with a mean of (55.30±6.52) years old ranging 43 to 65 years. The disease duration ranged from 3 to 36 months with a mean of(12.4±13.3) months. The disease distribution was as follows:lumbar disc herniation (7 cases), lumbar spinal stenosis (5 cases), and lumbar spondylolisthesis (2 cases). Operative time, incision length, intraoperative blood loss, number of intraoperative fluoroscopic exposures, time to ambulation, postoperative hospital stay, and complications were recorded. The dural sac area at the affected segment, visual analogue scale (VAS) for low back pain and leg pain, and Oswestry disability index (ODI) were recorded preoperatively and postoperatively. The modified MacNab criteria were used to evaluate the surgical outcome at the final follow-up. RESULTS: All 17 patients successfully underwent surgery and were followed up for 3 to 15 months with a mean of (8.4±3.3) months. The operative time was 120 to 200 minutes with a mean of (143.2±22.0) minutes, the incision length on the decompression side was 1.80 to 4.00 cm with a mean of (2.56±0.65) cm, intraoperative blood loss was 50 to 300 ml with a mean of (161.2±72.5) ml, the number of fluoroscopic exposures was 15 to 38 with a mean of (23.4±6.5), time to ambulation was 24 to 72 hours with a mean of (49.2±11.9) hours, and postoperative hospital stay was 3 to 9 days with a mean of (4.9±1.5) days. Two patients developed transient lower limb pain and numbness, which completely resolved with conservative treatment. The postoperative dural sac area was (121.47±14.90) mm², which was significantly larger than the preoperative area (51.47±7.69) mm²(P<0.001). The VAS for low back pain were (6.23±1.64), (2.94±1.43), and (1.94±0.75) at preoperation, 3 days postoperation, and final follow-up, respectively;the VAS for leg pain were (7.06±1.43), (2.35±1.17), and (2.06±0.90) at the same time points. The VAS at all postoperative time points were significantly lower than preoperative scores (P<0.001). The ODI at final follow-up was (25.29±8.15)%, which was significantly better than the preoperative ODI of(82.35±5.16)%(P<0.001). At the final follow-up, the MacNab surgical outcome was excellent in 11 cases, good in 4 cases, and fair in 2 cases. CONCLUSION OSE-assisted TLIF is an effective, safe, and minimally invasive technique with a gentle learning curve for the treatment of lumbar degenerative diseases, capable of effectively relieving symptoms and improving function.

With advancements in surgical technology, minimally invasive and function- preserving approaches have become fundamental objectives of both patients and physicians. In recent years, laparoscopic endoscopic cooperative surgery (LECS) has gained increasing attention for its significant role in achieving these goals. However, a notable gap remains in the availability of evidence-based guidelines to standardize the clinical implementation of LECS for gastrointestinal tumors. This guideline is collaboratively developed by the Gastrointestinal Stromal Tumor Committee of the Chinese Anti-Cancer Association, Chinese Gastric Cancer Association, the NOTES Group of the Digestive Endoscopy Branch of the Chinese Medical Association, and the Greater Bay Area Laparoscopic Endoscopic Cooperative Surgery Alliance. Through integrating the current best evidence and experts' opinions, we developed 22 recommendations on 16 clinical questions, including the LECS indications, use of antibiotics, enhanced recovery after surgery, wound suture, and surgical training. This guideline provides comprehensive guidance and recommendations for LECS, aimed at promoting the precise, minimally invasive and function-preserving treatment of gastrointestinal tumors.

The clinical application of binocular endoscope relies primarily on the visual system of physicians to create a three-dimensional effect, but it cannot provide accurate depth information. The utilization of 3D reconstruction technology in binocular endoscopy can facilitate the recovery of image depth information, and the application of deep learning-based 3D reconstruction technology can significantly improve the accuracy and real-time performance of reconstruction results, making it widely applicable in the realm of minimally invasive surgery. This paper aims to explore the key technologies and implementation methods of deep learning based 3D reconstruction for binocular endoscopic images, and seeks to outline strategies for enhancing the quality of 3D reconstruction in endoscopic images, providing guidance for sustainable development of binocular endoscopic image reconstruction technology in clinical settings. This will assist in the application of minimally invasive surgery and contribute to meeting the demands of precision medicine.

OBJECTIVES: In the early stage of central cervical disc herniation, clinical symptoms may be mild. However, as the spinal cord becomes compressed by herniated nucleus pulposus tissue, progressive edema and degeneration may occur, resulting in more severe clinical manifestations, including limb weakness, bladder and bowel dysfunction, spastic paraplegia of the lower extremities, and even respiratory difficulty. The spinal endoscopic Key-hole technique is widely applied in treating radiculopathic cervical spondylosis and has demonstrated good clinical outcomes. This study aims to analyze and summarize the technical points and therapeutic efficacy of the far lateral Key-hole technique in the treatment of central cervical disc herniation, providing reference for clinical application. METHODS: Eight patients with central cervical disc herniation treated with the far lateral Key-hole technique were included as the experimental group. Another 8 patients who underwent single-level anterior cervical diskectomy and fusion (ACDF) during the same period were selected as the control group. Data collected included gender, age, intraoperative blood loss, incision length, and length of hospitalization. Pain severity was evaluated using the Visual Analogue Scale (VAS); cervical function was assessed using the Japanese Orthopaedic Association (JOA) score; and cervical disability was measured by the neck disability index (NDI). Radiological outcomes were assessed using disc height index (DHI), cervical Cobb angle, and operative segment Cobb angle. RESULTS: Compared with the control group, the experimental group had significantly less intraoperative blood loss, shorter incision length, and shorter hospital stay (all P<0.05), while there was no significant difference in operation time (P>0.05). Postoperative VAS and NDI scores in both groups were significantly lower than preoperative values, and JOA scores significantly improved (P<0.05). No significant differences were noted between the two groups preoperatively (P>0.05). Postoperatively, the experimental group showed significantly lower VAS and NDI scores and higher JOA scores than the control group (P<0.05). There was no statistical significance in DHI before and after surgery in the experimental group (P>0.05), while the DHI increased significantly postoperatively in the control group (P<0.05). Postoperative DHI in the experimental group was significantly lower than in the control group (P<0.05). No significant differences were observed in the cervical Cobb angle either within or between groups (all P>0.05). The operative segment Cobb angle increased significantly after surgery in the control group (P<0.05), while no other operative segment angle changes were statistically significant (all P>0.05). CONCLUSIONS The far lateral Key-hole technique offers advantages in treating central cervical disc herniation, including reduced intraoperative bleeding, smaller incision length, shorter hospitalization, and improved postoperative pain relief. Additionally, the technique does not affect cervical physiological curvature or stability in the short term, making it suitable for clinical application.

Objective:This study aims to investigate the differences in hemostatic efficacy and patient comfort between an innovative domestically produced biodegradable nasal packing sponge and a traditional absorbent sponge following endoscopic nasal surgery. Methods:A prospective, randomized controlled trial design was utilized, including 30 patients who were divided into two groups according to random allocation, each receiving one of the two types of nasal packing. The study assessed the hemostatic efficacy, comfort, and safety of the materials by comparing the rates of no bleeding within 24 hours after packing, re-bleeding rates after 48 hours, pain ratings in the head and nasal areas, scores on a visual analog scale for nasal ocular symptoms, and safety indicators between the two groups. Results:The rates of no bleeding within 24 hours post-packing were 73.33% for both the experimental and control groups, with a no-bleeding rate of 100% after 48 hours in both groups. The pain rating in the head and nasal areas at various times post-packing was Grade Ⅰ（100%） in both groups, with no statistically significant difference（P=1.000）. The experimental groups sneezing score on the day of packing was（0.73±1.03）, lower than the control groups（2.27±1.67）, （P=0.007）; after 48 hours, the experimental groups sneezing score was（0.67±0.98）, also lower than the control groups（1.67±1.18）, （P=0.019）. There was no significant difference between the two groups in the Lund-Kennedy scoring during endoscopic examinations at the screening period, 7 days, 1 month, and 3 months post-packing（P>0.05）. Laboratory tests for other examination indicators were normal in both groups. Conclusion:The innovative domestically produced biodegradable nasal packing sponge not only provides hemostatic efficacy comparable to imported materials but also significantly improves patient comfort after surgery. It represents an economical and effective choice for nasal packing materials.

Objective:To investigate the occurrence and managements of poor recovery after total endoscopic middle ear surgery. Methods:A total of 302 cases（315 ears） who underwent endoscopic middle ear surgery in our hospital from June 2020 to June 2021 were collected. Follow up by means of endoscopy, pure tone hearing threshold, tympanogram was conducted at 1 month, 3 months, 6 months and 1 year after surgery to analyze the incidence, possible causes, treatment strategies and effects of poor results tympanic membrane healing and hearing recovery. Results:Among 302 patients（315 ears） followed up, there were 28 cases with poor recovery. There were fourteen cases of poor eardrum healing, of which 10 cases achieved healing of eardrum after tympanic membrane patching in the outpatient department, with a success rate of about 71.4%. TM recurrence adhesion occurred in 4 cases after surgeries of cholesteatoma and adhesive otitis media. One case completely recovered after self eustachian tube insufflation, while 2 cases maintained the degree of eardrum subsidence, and one ineffective patient chose resurgical treatment, with an effective rate was 75.0%. Failure in hearing improvement occurred in 8 cases, all of which underwent second surgical exploration, and seven cases were improved after the second surgery, with an effective rate of 87.5%. Among the 8 patients with no improvement or aggravation of hearing loss after surgery, four cases had postoperative B-type or C-type of tympanogram, and the hearing could not improve after self eustachian tube insufflation for secondary surgical exploration. and the hearing improved after the secondary surgery. Incorrect orientation of ossicular prosthesis was accounted for another 2 cases, the hearing was improved after the ossicular orientation adjustment. One patient with lateral healing of TM and failed hearing recovery was corrected by a second operation. One case of tympanosclerosis underwent stapes release surgery, but hearing recovery still failed. One patient had recurrent postoperative cicatricial atresia of external auditory canal, and the patient was reluctant to undergo reoperation. Postoperative delayed facial paralysis occurred in 1 case, and the facial paralysis recovered recovered after conservative treatments. Conclusion:Eardrum patch and eustachian tube autoflation are simple and effective early outpatient treatment for patient with poor recovery. For those who failed with conservative treatments such as eardrum patch or eustachian tube and poor hearing recovery, the second surgical exploration is safe and effective. Regular follow up after endoscopic middle ear surgery is necessary for the managements of poor recovery.
