BackgroundPrecise preoperative localization is of great importance to improve the success rate and reduce the operation time of VATS surgery. This study aimed to assess the efficacy, safety, patient perception between CT-guided indocyanine green (ICG) preoperative localization of lung nodule and hook-wire localization.Methods65 patients with 85 clinically suspicious pulmonary nodules underwent ICG preoperative localization in this study, and 92 patients with 95 nodules localized by conventional hook-wire served as controls. Both hook-wire localization and ICG injection were performed under CT guidance. Successful targeting rate, success rate in the operative field, incidence rate of complications and respiratory pain score were recorded and compared.ResultsThe successful targeting rate for both groups is 100%, however, due to hook-wire dislodgement, the success rate in the VATS operation field of the hook-wire group (95.6%) is lower than that of the ICG group (100%), with no significant difference(p=0.056). The overall complication rate of the hook-wire group (37.0%) is significantly higher than the ICG group (35.4%) (p=0.038). The mean respiratory pain score of the hook-wire group is 3.70 ± 1.25, which is significantly higher than that of the ICG group (2.85 ± 1.05) (p<0.001).ConclusionsICG composed with contrast mixture are superior to the conventional hook-wire preoperative lung nodule localization procedure, with a lower complication rate, lower pain score, and relatively higher success rate. ICG is a promising alternative method for pulmonary nodule preoperative localization.

Abstract Objectives: Video assisted thoracoscopic surgery (VATS) can currently be used to diagnose and treat pulmonary nodules. However, intraoperative location of pulmonary nodules in VATS is challenging due to their small diameter and deep location in the pulmonary parenchyma. The purpose of this study was to report the clinical safety and effectiveness of CT-guided hook-wire for preoperative localization of malignant pulmonary nodules smaller than 1 cm in diameter.Methods: From February 2017 to January 2018, we collected the data of 80 patients with malignant pulmonary nodules less than 1 cm in diameter who underwent CT-guided hook-wire preoperative localization and VATS surgery. The effectiveness of preoperative localization was evaluated based on surgical duration, success rate of VATS surgery, and localization-related complications.Results: The diameter of pulmonary nodules were 0.85 ± 0.17 mm with a distance to the pleural surface of 19.66 ± 14.10 mm. The length of the hook-wire in the lung parenchyma was 29.17 ± 13.14 mm and hook-wire dislodgement occurred in 2 patients. Complications included 27 cases of minor pneumothorax and 18 cases of mild parenchymal hemorrhage. A significant correlation was observed between the length of the hook-wire in the lung parenchyma and mild parenchymal hemorrhage (P = 0.044). The average time of hook-wire localization was 9.0 ± 2.6 min and the average operation time for VATS was 89.02 ± 23.35 min without conversion thoracotomy.Conclusions: CT-guided hook-wire localization of the lesion during VATS resection is safe for malignant pulmonary nodules with diameter less than 1 cm.

Objectives: To compare the efficacy and safety of preoperative localization of ground glass nodule (GGN) using embolization microcoils and the locating needles designed for pulmonary nodules. Methods: From June 2019 to December 2020, 429 patients who received CT-guided localization of single GGN before video-assisted thoracoscopic surgery (VATS) were enrolled. The diameter and depth of GGNs were 0.84 ± 0.39 cm and 1.66 ± 1.37 cm. Among 429 cases, the first 221 GGNs were marked with microcoils (the microcoil group), and the remaining 208 GGNs were marked with the locating needles designed for pulmonary nodules (the locating needle group). SPSS 17.0 statistical software was used to compare the marking success rate, marking time, marking-related complications between two groups. p values < 0.05 were considered statistically significant. Results: The marking time in the microcoil group was longer than that in the locating needle group (11.1 ± 3.9 vs 8.2 ± 2.0 min, t = −7.87, p = 0.000). The marking success rate in the microcoil group was lower than that in the locating needle group (91.4% vs 98.6%, χ2 = 11.27, p = 0.001). In the microcoil group, marking failures included 16 cases of microcoil dislocation and 3 cases of unsatisfactory microcoil position, while all 3 cases of marking failure in the locating needle group were due to unsatisfactory anchor position. No significant differences in the incidence of total complications (23.1% vs 22.1%), pneumothorax (18.1% vs 19.2%), hemorrhage (9.5% vs 9.1%), and hemoptysis (1.8% vs 1.4%) were observed between the two groups. All the complications were minor and did not need special treatment. Except for one case in the microcoil group, which was converted to thoracotomy, the remaining 428 GGNs were successfully resected by VATS. Conclusions: It is safe and effective to perform preoperative localization of GGN using either embolization microcoil or the locating needle designed for pulmonary nodules. The locating needle is superior to microcoil for marking GGN in terms of procedure time and the success rate. The complication rate of both methods is similar. Advances in knowledge: The locating needle designed for pulmonary nodules has recently been used to mark pulmonary nodule. Its structure can effectively avoid dislocation after localization, and the marking process is simple and quick. Compared with localization using microcoil, it takes less time and has higher success rate to mark GGNs using the locating needle. The complication rate of both methods is similar.

Rationale and Objectives. The aim of this study is to determine the effect of needle size on the diagnostic yield and complication rate of lung nodule biopsy. Materials and Methods. A total of 209 patients are included in a retrospective study. All patients underwent a needle lung biopsy under computer-tomography-guided guidance. Multiple different needle gauges are used in this study. Results. We found no correlation between the gauge of the needle and the incidence of complications or diagnostic yield associated with lung nodule biopsy. However, there was a statistically significant difference in the number of needle passes and the gauge of the needle (). Conclusion. Using a larger gauge needle does not correlate with an increase in complication rate. However, there is a statically significant decrease in the number of needle passes using a larger gauge needle. While the diagnostic yield comparing small gauge needle and large gauge needle was not statistically different, this lack of difference in yield could be related to the difference in number of passes. The use of larger needle is likely to decrease number of passes, thereby resulting in decreased procedure times.

Background: To compare distal transradial access (dTRA) in the anatomic snuffbox and conventional transradial access (cTRA) for coronary angiography. Methods: Eighty cases that underwent coronary angiography were selected at The 903 Hospital of PLA in China from April 2017 to March 2018. Patients in the dTRA group underwent distal transradial access, and patients in the cTRA group received conventional transradial access. Puncture success rate, fluoroscopy time, and hemostasis time were determined. Results: The puncture success ratio was 85% in the dTRA group and 100% in the cTRA group (P < .05). The fluoroscopy time was 36 minutes and 19 min minutes in the dTRA group and cTRA group (P < .05), respectively. The compression hemostasis time after operation was 120 minutes and 240 minutes in the dTRA group and cTRA group (P < .05), respectively. The complication rate in the cTRA group was 7.5%, while there was no complication in the dTRA group. In addition, there also was no significant difference between the two groups in the rate of complications (cTRA = 7.5%, dTRA = 0.0%, P > .05). Conclusion: Distal transradial access in the anatomical snuffbox for coronary angiogram is a potential alternative to conventional radial arterial access.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Aims: Management of inflammatory renal disease (IRD) can still be technically challenging for laparoscopic procedures. The aim of the present study was to compare the safety and feasibility of laparoscopic and hand-assisted laparoscopic nephrectomy in patients with IRD. Patients and methods: We retrospectively analyzed the data of 107 patients who underwent laparoscopic nephrectomy (LN) and hand-assisted laparoscopic nephrectomy (HALN) for IRD from January 2008 to March 2020, including pyonephrosis, renal tuberculosis, hydronephrosis, and xanthogranulomatous pyelonephritis. Patient demographics, operative outcomes, and postoperative recovery and complications were compared between the LN and HALN groups. Multivariable logistic regression analysis was conducted to identify the independent predictors of adverse outcomes. Results: Fifty-five subjects in the LN group and 52 subjects in the HALN group were enrolled in this study. In the LN group, laparoscopic nephrectomy was successfully performed in 50 patients (90.9%), while four (7.3%) patients were converted to HALN and one (1.8%) case was converted to open procedure. In HALN group, operations were completed in 51 (98.1%) patients and conversion to open surgery was necessary in one patient (1.9%). The LN group had a shorter median incision length (5 cm versus 7 cm, p < 0.01) but a longer median operative duration (140 min versus 105 min, p < 0.01) than the HALN group. There was no significant difference in blood loss, intraoperative complication rate, postoperative complication rate, recovery of bowel function, and hospital stay between the two groups. Multivariable logistic regression revealed that severe perinephric adhesions was an independent predictor of adverse outcomes. Conclusion: Both LN and HALN appear to be safe and feasible for IRD. As a still minimally invasive approach, HALN provided an alternative to IRD or when conversion was needed in LN.

Abstract Background To compare 6 month outcomes of bleb needling performed in the clinic vs. the operating room (OR) in adult glaucoma patients with failed bleb. Methods A retrospective case series of 47 eyes from 41 glaucoma patients who received needling with mitomycin C (MMC) of scarred bleb from prior bleb-forming procedures in clinic (32 eyes) vs. the OR (15 eyes), including trabeculectomy (14 eyes), ExPress shunt (16 eyes), and ab-interno XEN gel stent (17 eyes). The primary outcome was needling success, defined as IOP ≤ 18 mmHg on 0 glaucoma medications without requiring an additional IOP lowering procedure within 6 months after needling. Results At 6 months, bleb needling success rate was similar when performed in the clinic vs. in the OR (28% vs. 20%, P = 0.54). Success rate was not statistically different in patients with prior trabeculectomy, ExPress shunt, and XEN gel stent (29% vs. 38% vs. 12%, P = 0.26). When comparing clinic vs. the OR needling procedures at 6 months, there was no difference in mean IOP (14.2 vs. 14.9 mmHg, P = 0.73), mean glaucoma medications (1.4 vs. 1.7, P = 0.69), additional IOP-lowering procedure rate (16% vs. 27%, P = 0.37), or complication rate (0% vs. 7%, P = 0.32). Conclusion Bleb needling with MMC in clinic may be a safe and effective way to revise failed bleb after trabeculectomy, ExPress shunt, and XEN gel stent procedures when compared to needling in the OR.
