ABSTRACT

With the development of CT and the popularization of health examination, the detection rate of small pulmonary nodules has been improved. Some small pulmonary nodules could be malignant nodules. Surgical resection is the preferred treatment. Therefore, it is an important task for thoracic surgeons to accurately locate pulmonary nodules during surgery and remove nodules accurately on the premise of maximum protection of lung function. At present, the core of preoperative auxiliary localization of pulmonary nodules is the implantation of markers. The commonly used clinical localization methods include hook wire localization, microcoil localization, methylene blue puncture injection localization and biological glue localization. In this paper, the development status, application scope, advantages and disadvantages of existing localization methods are briefly reviewed, which can provide references for clinical application and follow-up research.

ABSTRACT

Objective:To verify the feasibility of a self-designed laparoscopic magnetic anchoring device for assisting thoracoscopic wedge resection.Methods:Six healthy Beagle dogs were selected as animal models, and underwent thoracoscopic wedge resection after general anesthesia. We replaced the pulmonary forceps with a magnetic anchoring device to complete the traction exposure of the lobes, and recorded the operation time of the operation, the amount of intraoperative blood loss, and the safety and feasibility of the magnetic anchoring device.Results:Six Beagle dogs successfully completed a thoracoscopic wedge resection with the aid of a magnetic anchoring device. During the operation, the magnetic anchoring device can completely replaced the exposure function of the pulmonary forceps, effectively eliminating the " chopstick effect" between the instruments during the uniportal video-assisted thoracoscopic operation. The magnetic anchoring device provided sufficient traction for the surgery to achieve a clear exposure of the field. Tissue damage and magnetic anchoring pliers slip did not occur during the operation. The operation time was(22.67±3.25)min(range 18-26 min), and the intraoperative blood loss was less than 10 ml. The experimental animals survived well after surgery.Conclusion:Magnetic anchoring device is safe and effective for thoracoscopic wedge resection, which can eliminate mutual interference between operating instruments and has potential for clinical application.

ABSTRACT

Objective:To study the feasibility of establishing gastrointestinal anastomosis by magnetic compression technique in rabbits.Methods:Ten healthy New Zealand rabbits were selected as models for gastrointestinal anastomosis by magnetic compression technique. Daughter and parent magnets suitable for gastrointestinal anastomosis in rabbits were designed and manufactured. A daughter magnet was inserted into the stomach through the purse fistula in the lack of blood vessel area of gastric body, and was pushed into the duodenum along the intestinal tract. And then a parent magnet was inserted through the stomach fistula. The daughter and parent magnets were automatically attracted and pressed the gastric and intestinal walls after they were adjusted in the proper position. The stomach fistula was closed with purse string suture. After ischemia, necrosis, detachment of the tissues between magnets, gastrointestinal anastomosis was established, and the magnets and necrotic tissues were expelled together from the body through the digestive tract. Survival of experimental animals was observed. Anastomotic specimens were obtained one month after operation. The blasting pressure of anastomotic stoma was measured, and the healing of anastomotic stoma was observed with naked eyes.Results:According to the pre-designed operative route, 10 New Zealand rabbits all successfully completed the operation and survived one month after surgery. No complications occurred during perioperative period. The operation time was 35.80±4.71 min (range 28.00-43.00 min), and the magnet discharge time was 11.40±1.56 days (range 9.00-14.00 days). Anastomotic specimens were obtained one month after the operation. Gross observation showed that the anastomotic stoma of gastrointestinal bypass anastomosis healed well, and the surrounding tissues adhered slightly. The anastomotic bursting pressure was 103.00±7.95 mmHg (range 94.00-113.00 mmHg) (1 mmHg=0.133 kPa).Conclusion:The establishment of gastrointestinal anastomosis by magnetic compression technique in rabbits is simple and effective.

ABSTRACT

Objective:To design magnets to locate colorectal neoplasms based on magnetic tracer technology, and to test its feasibility and safety by animal experiments.Methods:The magnets used for endoscopic localization of colorectal tumors consist of a tracer magnet and a pursuit magnet, both of which are ring-shaped Nd-Fe-B magnets. Eight healthy Beagle dogs were used as animal models. Tumor locations were assumed in the different parts of the colon and rectum under colonoscopy. The tracer magnet was sent to the hypothetical tumors by endoscopic soft tissue clamp and fixed near the tumors. After 24 hours, laparoscopic surgery was performed under general anesthesia. The pursuit magnet was inserted near the resected colon or rectum through the main operating hole. The tracer magnet was absorbed to the pursuit magnet to identify the location of tumors.Results:The tracer magnet and pursuit magnet were successfully designed and processed. The suction force between the tracer magnet and the pursuit magnet at zero distance was 16 N. All the 8 Beagle dogs successfully received indwelling of magnets under colonoscopy, and no magnets fell off after 24 hours. After the placement of pursuit magnet under laparoscopy, the two magnets attracted each other rapidly and accurately, and successfully completed localization of tumor site without any damage during the operation.Conclusion:Colonoscopy combined with laparoscopy for colorectal neoplasms localization based on magnetic tracer technique is simple, accurate, safe and feasible.

ABSTRACT

Objective To evaluate the prognostic value of pathological characteristics of microvascular invasion (MVI) in patients with hepatocellular carcinoma (HCC).Methods 289 consecutive HCC patients who underwent curative hepatectomy at Nanjing Drum Tower Hospital from January 2007 to December 2015 were retrospectively studied.These patients were divided into three groups:the no-MVI group (n =176),the low-MVI group (the number of invaded microvessels ≤ 5 and the distance of invasion ≤ 1 cm,n =53) and the high-MVI group (the number of invaded microvessels > 5 or the distance of invasion > 1 cm,n =60).The clinical and pathological data and the survival outcomes of these HCC patients were analyzed.We further compared the prognosis among the three groups.Results Kaplan-Meier survival indicated that the number of invaded microvessels > 5 and the distance of invasion > 1 cm were associated with cumulative and recurrence-free survival rates of HCC patients.The cumulative and recurrence-free survival rates of the high-MVI group were significantly poorer than those of the low-MVI and the no-MVI groups.Multivariate analysis showed ICG-R15 (HR =1.049,95% CI:1.002 ~ 1.097),tumor size (HR =1.138,95% CI:1.043 ~ 1.241),and high-MVI (HR =3.245,95% CI:1.946 ~ 5.413) were independent risk factors for cumulative survival.Tumor size (HR =1.117,95% CI:1.050 ~ 1.188),and high-MVI (HR =2.222,95% CI:1.540 ~ 3.205) were independent risk factors for recurrence-free survival.The prognosis of the no-MVI and low-MVI groups were significantly better than the high-MVI group (P < 0.05).The recurrence rates of the low-MVI and no-MVI groups (49.4% and 67.9%) were significantly lower than the high-MVI group (80.0%,P < 0.05).Conclusions The risk classification of MVI based on histopathological features was valuable in predicting prognosis of HCC patients.We could use the risk classification of MVI to establish a follow-up and individualized treatment plan for HCC patients.

ABSTRACT

Laparoscopic surgery based on magnetic anchor technique has great potential for further minimally invasive surgery and good surgical field exposure, in which the internal grasper is the key factor. In this paper, an internal grasper based on magnetic anchor laparoscopic surgery is designed, which consists of three parts:target magnet, connection module and tissue forceps. The magnetic shield shell is used to wrap the magnetic core in the target magnet, which not only can increase the magnetic force in the working area, but also reduce the magnetic interference between the instruments, and the connecting module can flexibly adjust the length of the internal grasper. The special structure of tissue gripper can effectively reduce deputy injury and facilitate the replacement of clamp position. It has many advantages, such as ingenious design, easy processing, simple operation and wide range of application, which greatly increased its clinical application value.

ABSTRACT

Magnetic anchor technique can reduce the number of trocar in laparoscopic surgery. The laparoscopic magnetic anchor system consists of an external anchor magnet and the magnetic clutch system. Electromagnetic control laparoscopic surgery clutch system includes the internal grasper and the operating forceps. In this design, a permanent magnet is set at the tail of the internal grasper, and an electromagnetic device is installed at the head of the operating forceps. The magnetic field direction of the electromagnetic device can be changed by switching the positive pole and the negative pole of the electromagnetic device, so as to control the separation and combination of the operating forceps and the internal grasper. The design of this system is ingenious, easy to manufacture and the operation is simple.

ABSTRACT

Objective To investigate the predictive values of preoperative radiological features-intratumoral arteries and tumoral morphological classification on microvascular invasion (MVI) and on prognosis in patients with hepatocellular carcinoma (HCC).Methods A total of 220 consecutive HCC patients who underwent curative hepatectomy at Nanjing Drum Tower Hospital from January 2008 to December 2014 were retrospectively analyzed.The predictive values of preoperative radiological features and clinical data on MVI were analyzed by the univariate analysis and multivariate logistic regression methods.The prognosis of HCC patients was analyzed by the Kaplan-Meier survival analysis and the Cox proportional hazards models.Results Univariate analysis and multivariate logistic regression showed intratumoral arteries and tumoral morphological classification using preoperative CT[called the radiological predictorsof microvascular invasion (RPMVI)] to be independent predictors of MVI.The AUROC for RPMVI inpredicting MVI was O.830 (95% CI,O.769 ~ 0.891,P <0.05).The Cox multivariate analysis identified Child-Pugh grading,tumor size > 5 cm,RPMVI,MVI and non-anatomical liver resection to be independent risk factorsof overall survival (OS),while tumor size > 5 cm,RPMVI,MVI and non-anatomical liver resection to be independent risk factor sofre currence-free survival (RFS).The 1-,3-,and 5-year OS rates were 83.3%,61.7%,and 40.1% in patients with RPMVI and 97.1%,76.5%,and 69.6% in patients without RPMVI (P <0.05),respectively.The 1-,3-,and 5-year RFS rates were 61.9%,36.9%,and 28.4% in patients with RPMVI and 81.6%,61.9%,and 52.2% in patients without RPMVI (P < 0.05),respectively.Conclusions RPMVI is a novel radiological marker that accurately predicted histological MVI in HCC patients preoperatively.Similar to MVI,RPMVI was found to be an independent risk factor for prognosisin HCC patients,and it may provide the important information for surgical treatment planning in HCC patients.

ABSTRACT

Objective To evaluate the CT spectral imaging in assessing the therapeutic efficacy of axitinib in rabbit VX2 liver tumors. Methods Thirty-two VX2 liver tumor-bearing rabbits (diameter 1.0 to 2.5 cm) were prospectively and randomly assigned into the study group (axitinib treated group, n=16) or the control group (pseudo-therapy group, n=16). They were treated with axitinib or saline by using the gastric tube respectively. All the rabbits underwent unenhanced, arterial-phase (AP) and portal-phase (PP) contrast enhanced CT examinations by using spectral CT at different time points (baseline, 2, 4, 7, 10 and 14 days after treatment). Tumor size (TS) at each time point was recorded to calculate the percentage change (ΔTS)after treatment relative to baseline. Iodine concentration (IC) of the entire tumor, the peripheral hypervascular region and the center of the tumor were measured and normalized to aorta (NIC) to generate the difference for the NIC (NICD) between a given time and baseline. The tumorΔTS and NICD between the control and treated groups were compared by using Mann-Whitney U test. Serial changes in NICD at different time points were evaluated by using Wilcoxon signed rank test. Correlations between the NICD andΔTS, between NIC and microvessel density (MVD) were analyzed. Results The tumorΔTS after treatment in the control group and study group increased continuously. The tumorΔTS was significantly smaller in the treated group than that in the control group at day 7, 10 and 14. At day 2 , 4 and 10 after treatment, each tumor NICD in the study group was smaller compared with the control group(P0.05).Conclusion CT spectral imaging allows the evaluation and early prediction of tumor response to axitinib in rabbit VX2 liver tumors.

ABSTRACT

Objective To investigate the image quality and radiation dose of automatic spectral imaging mode selection and adaptive statistical iterative reconstruction (ASIR) at abdominal CT with low contrast agent dose. Methods One hundred cases with the arterial-phase (AP) and portal venous phase (PVP) contrast-enhanced abdominal CT scanning were analyzed prospectively. Patients were randomly assigned to the study group and control group (n=50 each). In the study group, automatic spectral imaging mode selection and contrast agent dose of 300 mg/kg were used and spectral monochromatic images(40 to 60 keV) were reconstructed using either filtered back-projection (FBP) (group A) or ASIR (group B). In the control group, the fixed tube potential of 120 kVp and contrast agent dose of 450 mg/kg were used with images reconstructed using FBP (group C). Quantitative parameters (image noise and contrast-to-noise ratio of the liver, pancreas, aorta and portal vein) and qualitative visual parameters (overall image quality as graded on a 5-point scale) were compared among the groups by using One-way ANOVA or Kruskal-Wallis H test. Two sample t tests were used compare the radiation dose difference. Results There had no significant difference in CTDIvol[both (12±5) mGy] and DLP[(364±142) mGy·cm versus (377±131) mGy·cm] between the study group and control group(t=-0.408 and-0.428,P>0.05). During the AP and PVP, at the energy level of 40 keV, group B showed higher CNRs than group A and group C, lower image noise[ (29±6) HU in AP, (24±6) HU in PVP] than group A[(43±11) HU, (44±10) HU] but higher image noise than group C[ (18± 4) HU, (18±4) HU], lower overall image quality scores[(3.0±0.2) point, (2.9±0.3) point] than group C[(3.6± 0.4) point , (3.6±0.5) point] but similar scores to group A[(2.9±0.4) point,(2.8±0.4)point]. At the energy level of 50 keV, group B showed higher CNRs than group A but higher than or similar CNRs to group C, lower image noise[ (20±5) HU, (20±4) HU] than group A[(31±8) HU, (31±7) HU] but similar image noise to group C, higher overall image quality scores[(3.6±0.4) point, (3.5±0.4) point]than group A[(3.3±0.3) point,(3.3±0.3) point] but similar scores to group C. At the energy level of 60 keV, group B showed lower image noise[(14±4) HU, (14±3) HU], higher CNRs and overall image quality scores[(3.9±0.4) point,(3.9±0.3) point] than group A[(19 ± 5) and (20 ± 5)HU in image noise, (3.7 ± 0.4) and (3.7 ± 0.3) point in overall image quality scores ]and group C. Except for monochromatic images at 40 keV, the overall image quality scores in group B were all greater than 3 point and met the clinical diagnostic level. Conclusions The radiation dose of CT spectral imaging and conventional 120 kVp CT scan is equivalent with the use of automatic spectral imaging mode selection. By combining ASIR technique, monochromatic images at 50 and 60 keV can improve CNR and reduce contrast agent dose while maintain or improve overall image quality.
