Objective:To investigate the efficacy and safety of fluoroscopically-guided percutaneous gastrostomy (FGPG) for establishing enteral nutrition access in the treatment of esophageal fistula after radiotherapy for cervical esophageal cancer (CEC).Methods:A retrospective analysis was conducted on the clinical data of 54 patients who underwent FGPG due to esophageal fistula after radiotherapy for CEC at our department from November 2009 to August 2019. All patients received endoscopy before radiotherapy, and CEC was pathologically confirmed. Enteral nutrition support was offered through a gastrostomy tube postoperatively. The success rate of FGPG, complications, and healing of perforation were recorded and analyzed.Results:FGPG was successfully performed in all 54 patients (100%). During the 12-month follow-up, 50 patients (92.6) survived while four (7.4%) died. Among 36 patients with esophagomediastinal fistula, 32 (88.9%) healed in a median of 12 weeks; of 18 patients with esophagotracheal fistula, 8 (44.4%) healed in a median of 18 weeks. Thus, patients with esophagomediastinal fistula had a significantly higher healing rate ( P<0.01) and shorter healing time ( P=0.017). Gastrostomy tube-related complications were minimal, and no serious complication was noted. Conclusions:FGPG is effective for the treatment of esophageal fistula after CEC radiotherapy and may be an alternative treatment for esophageal fistula.

Objective:To analyze the research trends and hotspots of bupivacaine liposomes from 1994 to 2023 using bibliometrics.Methods:A comprehensive search was conducted for the literature related to bupivacaine liposomes in the Web of Science Core Collection from 1994 to 2023. The CiteSpace software was used to conduct an in-depth analysis of the included literature data, including publication year, country, institution, author, journal, cited references, keywords, etc.Results:A total of 875 papers related to bupivacaine liposomes were included. The research and development of bupivacaine liposomes were divided into 3 stages: slow development (1994-2011), a sharp rise (2011-2021), and stabilization (2021-2023). The United States was in a leading position in terms of the number of publications, centrality, and author cooperation, and Harvard University had the largest number of publications. de Paula E had the most publications, Bramlett K had the highest number of citations, and Boogaerts J had the highest centrality of publications. Journals such as Anesthesia and Analgesia made significant contributions to this field. The most cited references focused on the infiltration of wounds and the periprosthetic injection of bupivacaine liposomes. The keyword analysis showed that local anesthetics, postoperative pain, etc. were commonly used keywords, and enhanced recovery after surgery was an emerging hotspot. Conclusions:Bupivacaine liposomes show good application prospects in the field of peripheral nerve block due to their unique pharmacological properties and safety characteristics and are expected to prolong the duration of postoperative analgesia. However, there is a difference between the actual effect and the expectation, and more clinical trials are needed to evaluate the curative effect, providing a more solid and reliable theoretical basis and practical guidance for clinical practice.

Objective:Quantified MRCP imaging data was used as a reference for design and preparation of a modified percutaneous transhepatic cholangio drainage (PTCD) tube.Methods:3.0 T upper abdominal MR and MRCP imaging data of 2 300 patients treated from July 2015 to July 2020 at the Department of Radiology of the Affiliated Cancer Hospital of Zhengzhou University were screened and a total of 381 patients diagnosed with biliary duct structures were identified. Causative etiologies among these patients included pancreatic adenocarcinoma (pancreatic head), cholangiocarcinoma, ampullary carcinoma, as well as intrahepatic and/or extrahepatic bile duct dilation. An improved PTCD tube was designed based on MRCP quantification of left and right hepatic and common hepatic duct length.Results:In the setting of biliary obstruction caused by malignancy, the distance of the left hepatic duct from its origin to the point of left and right hepatic duct confluence was 15.9±3.8 mm, while the distance of the right hepatic duct from its origin to the point of left and right hepatic duct confluence was 12.4±3.2 mm; the length of the bile duct from its origin to the point of left and right hepatic duct confluence was 34.0±8.1 mm. The improved PTCD tube design incorporated an altered length of the drainage orifice.Conclusion:MRCP imaging of the biliary tract is effective for measuring biliary tract length in the setting of pathological dilation. Based on our biliary tract measurements, a modified PTCD tube was designed to more effectively meet drainage requirements and manage biliary obstruction caused by Bismuth-Corlette type Ⅱ and Ⅲ malignancies.

Objective:To investigate the precautions and clinical effects of minimally invasive lateral bone transfer of tibia in the treatment of diabetic foot.Methods:A retrospective analysis was performed on 82 patients with diabetic foot admitted to the Trauma Department of Changzhou First People's Hospital from January 2019 to December 2022. According to the Wagner grade of diabetic foot, there were 12 cases of grade 2, 50 cases of grade 3, and 20 cases of grade 4. According to the surgical method, 45 patients were divided into bone transfer group. There were 29 males and 16 females, with an average age of 65.27±10.74 years (ranging from 44-87 years), who underwent minimally invasive bone transfer of tibia combined with local debridement treatment. In the non-bone transfer group, there were 37 cases (26 males and 11 females) with an average age of 66.05±11.08 years (ranging from 44 to 86 years), who were treated with local debridement. Gender, age, Wagner grade, surface temperature difference of the affected limb, visual analogue scale (VAS) score of the affected limb before and 1 month after surgery, wound healing rate 1 month after surgery, and recurrence rate of the affected foot 1 year after surgery were compared between the two groups. Outcomes of the cases of different Wagner grades were compared.Result:All 82 patients were followed up for 14.23±1.20 months. There was no significant difference in gender, age, Wagner grade and preoperative VAS between the two groups ( P>0.05). The skin temperature of the affected limb before and after surgery in the bone transfer group was significantly higher than that in the non-bone transfer group 1.93±0.31 ℃ ( P<0.05), and the VAS of the bone transfer group was 2.18±0.58 points 1 month after surgery, which was lower than that in the non-bone transfer group of 5.41±0.93. The VAS difference before and after surgery in the bone transfer group was 4.80±1.24 points, which was greater than that in the non-bone transfer group of 1.62±1.48 points with significant difference ( P<0.05). The wound healing rate was over 98.78%±2.17% in the bone transfer group and 52.57%±6.41% in the non-bone transfer group one month after surgery. No recurrence or recurrence was found in the bone transfer group one year after surgery, and the recurrence rate was 86% (32/37) in the non-bone transfer group with significant difference ( P<0.05). There was no difference in preoperative VAS for different grades of diabetic foot (grades 2, 3, and 4). There were significant differences in VAS, VAS decrease, postoperative limb surface temperature increase, local wound healing rate at 1 month, and lower limb ulcer recurrence or recurrence rate at 12 months in the bone transfer groups of Wagner grade 2, 3, and 4 ( P<0.05). Conclusion:Minimally invasive lateral bone transfer of tibia combined with local precision debridement could significantly increase the healing rate of diabetic foot ulcer, improve the peripheral microcirculation of the affected limb, reduce the pain of the affected limb, and decrease the recurrence rate of diabetic foot ulcer.
