ObjectiveTo evaluate the high-level disinfection effect of flexible endoscopes in the Endoscopy Center of the First People’s Hospital of Longquanyi District of Chengdu, explore the key links of flexible endoscope cleaning and disinfection, and provide theoretical guarantee and technical support for the next step of the endoscope center work.MethodsWe sampled and monitored the lumens, water and air injection ports and biopsy ports of 19 flexible endoscopes after high-level disinfection in the Endoscopy Center of the First People’s Hospital of Longquanyi District of Chengdu. A total of 307 specimens were collected from 108 flexible endoscopes. We compared the disinfection effects of different flexible endoscopes and different sampling sites, and compared the microbial detection status of different flexible endoscopes.ResultsThe qualified rates of disinfection of gastroscopes, colonoscope and duodenoscopy were 79.22%, 86.21% and 100.00%, respectively, and the difference was not statistically significant (P=0.721). The qualified rates of disinfection of the endoscopic lumen, water and air injection port and biopsy port were 87.04%, 93.00% and 94.95%, respectively, and the difference was not statistically significant (χ2=4.585, P=0.101). The qualified rates of the lumen, water and air injection port and biopsy port of gastroscope, colonoscope and duodenoscope were 84.42%, 93.10%, 100.00%, 92.96%, 92.59%, 100.00%, 94.29%, 96.30%, 100.00%, respectively. There was no statistically significant difference in the disinfection effect of various parts of different flexible endoscopes (P>0.05). Bacteriological identification showed that of the 28 specimens with excess bacteriological standards, 16 gram-positive bacteria (57.1%), and 12 gram-negative bacteria (42.9%) were found.ConclusionThe cleaning and disinfection effect of flexible endoscopes has certain defect. Endoscope should be treated in strict accordance with the technical specifications for cleaning and disinfection of the flexible endoscope to further improve the disinfection effect of the flexible endoscope.
Objective To evaluate the feasibility, safety, and early effectiveness of percutaneous endoscopic thoracic spine surgery via the trench technique for ventral decompression in central calcified thoracic disc herniation (CCTDH) and thoracic ossification of the posterior longitudinal ligament (T-OPLL). MethodsSeven patients with single-segment CCTDH or T-OPLL admitted between June 2017 and May 2020 and meeting the selection criteria were retrospectively analyzed. There were 3 males and 4 females with an average age of 51.7 years ranging from 41 to 62 years. There were 2 patients with T-OPLL (T1, 2 in 2 cases) and 5 patients with CCTDH (T1, 2 in 1 case, T7, 8 in 1 case, T10, 11 in 2 cases, T11, 12 in 1 case). Five patients with thoracic axial pain and intercostal neuralgia had a preoperative visual analogue scale (VAS) score of 6.0 (5.0, 6.5), and 7 patients had a preoperative Japanese Orthopaedic Association (JOA) score of 21 (21.0, 22.0). Transforaminal approach was used in 4 cases and transpedicular approach in 3 cases. Ventral decompression of thoracic spinal cord was performed by thoracic endoscopy combined with trench technique. The operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications were recorded. Thoracic spine CT and MRI were performed preoperatively and postoperatively to evaluate the surgical decompression, VAS score was used to evaluate the pain of thoracic back and lower limbs, and JOA score was used to evaluate the functional recovery. Modified MacNab criteria was used to evaluate the effectiveness. ResultsAll surgeries were successfully completed. The operation time ranged from 60 to 100 minutes, with an average of 80.4 minutes; the intraoperative blood loss ranged from 40 to 75 mL, with an average of 57.1 mL; the postoperative hospital stay ranged from 4 to 7 days, with an average of 5.4 days. CT and MRI examinations indicated that the decompression was adequate. All 7 patients were followed up 3-22 months, with an average of 13.3 months. One case developed postoperative wound infection, and 1 case developed pneumonia; the remaining patients did not have any complications such as wound infection or cerebrospinal fluid leakage. Five patients with thoracic axial pain and intercostal neuralgia had VAS scores of 2.0 (1.5, 2.5) at 1 day after operation and 2.0 (1.0, 2.0) at last follow-up, both of which were significantly lower than the preoperative scores (P<0.05). At 1 day after operation, the JOA scores for all 7 patients were 22.0 (21.0, 24.0), which showed no significant difference compared to the preoperative score (P>0.05); however, at last follow-up, the score improved to 24.0 (24.0, 26.0), which was significant compared to the preoperative scores (P<0.05). At last follow-up, the effectiveness was assessed using the modified MacNab criteria, the results were excellent in 2 cases, good in 3 cases, fair in 2 cases, and the excellent and good rate was 71.4%.ConclusionUsing the trench technique, percutaneous endoscopic thoracic spine surgery can achieve the ventral decompression in CCTDH and T-OPLL, providing a new approach for surgical treatment of CCTDH and T-OPLL.
To investigate the microsurgical management of cranionasal tumors and the method of the reconstruction of the skull base. Methods From June 2005 to October 2007, 20 patients with cranionasal tumor were treated. There were 10 males and 10 females, aged between 13 and 77 years (median 49 years). The disease course was 2 months to 13 years.The cranionasal tumors, proved by MRI and CT scans, located in the anterior skull base, paranasal sinus, nasal and/or orbit cavity. And their cl inical presentations were l isted as follows: dysosphresia in 14 patients, headache in 11 patients, nasal obstruction in 9 patients, epistaxis in 8 patients, visual disorder in 4 patients, exophthalmos in 4 patients and conscious disturbance in 2 patients. All 20 patients underwent transbasal surgery combined with transnasal surgery, and tumors were resected by one-stage operation. The skull base was reconstructed by surgical technique “Pull Down Sandwich” with pedicle periosteum flap. Results Tumors were resected by one-stage operation, and the anterior skull bases were reconstructed. Pathological examination showed 8 cases of mal ignant tumors and 12 cases of benign tumors. The total surgical excision was complete in 16 patients, and 4 patients with subtotal excision. There was no operative death. Eighteen patients were followed up 3 months to 2 years and 6 months. Transient cerebrospinal fluid rhinorrhea was found in 2 cases which were cured by lumbar drainage. And recurrence of tumor was observed in 5 patients 3 months to 2 years after operation. Conclusion Microsurgical operation via subfrontal approach assisted bytransnasal endoscopy is an effective method in management of cranionasal tumors, with the advantages of econstruction of the skull base with pedicle periosteum flap or “Pull Down Sandwich” and low compl ication rate.
Objective To determine the independent influencing factors of intraoperative choking during painless gastrointestinal endoscopy (PGIE) after coronavirus disease 2019 (COVID-19). Methods The data of patients undergoing PGIE with COVID-19 in Northern Jiangsu People’s Hospital between December 2022 and April 2023 were retrospectively collected. Multiple logistic regression analysis was used to screen the influencing factors of intraoperative coughing events that occurred during the diagnosis and treatment process. Results A total of 948 patients were included, with 93 (9.8%) cases of choking. The results of the multiple logistic regression analysis showed that smoking and unresolved cough were independent risk factors for coughing (P<0.05), while colonoscopy and infection duration beyond 14 days between diagnosis and treatment were independent protective factors for coughing (P<0.05). ConclusionsWhen patients with COVID-19 undergoing PGIE, special attention should be paid to high-risk groups such as smoking and unresolved cough. It is necessary to strengthen intraoperative monitoring and implementation of prevention and control measures to reduce the incidence of coughing and improve the safety of diagnosis and treatment for patients.
ObjectiveTo systematically review the diagnostic value of capsule endoscopy and enteroscopy in small intestinal diseases.MethodsPubMed, The Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were electronically searched to collect studies on the diagnosis of intestinal diseases by capsule endoscopy and enteroscopy from inception to August 31st, 2020. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. Meta-analysis was then performed by using RevMan 5.3 and Meta-DiSc software.ResultsA total of 20 studies were included. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for capsule endoscopy were 0.86 (95%CI 0.83 to 0.87), 0.81 (95%CI 0.78 to 0.84), 117.07 (95%CI 37.98 to 360.92), 7.20 (95%CI 2.81 to 18.45), 0.11 (95%CI 0.06 to 0.21), and those for enteroscopy were 0.89 (95%CI 0.87 to 0.90), 0.91 (95%CI 0.89 to 0.93), 196.99 (95%CI 72.63 to 534.26), 13.26 (95%CI 5.00 to 35.14), 0.12 (95%CI 0.07 to 0.21). The areas under the working characteristic curve (SROC) of capsule endoscopy and enteroscopy were 0.9692 and 0.9783, respectively.ConclusionsBoth capsule endoscopy and enteroscopy have high specificity and sensitivity in the diagnosis of small intestinal diseases, and enteroscopy has higher clinical value in the diagnosis of some small intestinal diseases than capsule endoscopy. Due to limited quantity and quality of the included studies, the above conclusions are required to be verified by more high-quality studies.

Lumbar spondylolisthesis is a common condition in spinal surgery, which is often characterized by lower back and leg pain and numbness. There are various treatment methods for this condition, and different treatment plans should be adopted according to different situations. Traditional open surgery methods are relatively traumatic and have longer recovery times, while minimally invasive spine techniques have advantages such as smaller incisions, less bleeding, higher fusion rates, and faster recovery. This review summarizes the relevant literature on the application of minimally invasive techniques in the treatment of lumbar spondylolisthesis in recent years, analyzes and compares the advantages and disadvantages of different approaches and endoscopic techniques, as well as reduction, decompression, and fusion effects. The aim is to provide reference for surgeons in selecting surgical procedures for the treatment of lumbar spondylolisthesis.
