ABSTRACT
Abstract Background Skin modification through tattoos is as old as humanity itself. However, this trend is on the rise, and with the use of different types of pigments and application practices, both cutaneous and systemic complications can arise. Adverse reactions can be grouped into five classes: inflammatory, infectious, neoplastic, aesthetic, and miscellaneous. On histopathology, inflammatory reactions can exhibit a lichenoid pattern or present as spongiotic dermatitis, granulomatous reactions, pseudolymphoma, pseudoepitheliomatous hyperplasia, or scleroderma/morphea-like changes. This article reviews tattoo complications, including their clinical and histopathological characteristics. Methods An open search was conducted on PubMed using the terms "tattoo", "complications", and "skin". No limits were set for period, language, or publication type of the articles. Results Reactions to tattoos are reported in up to 67% of people who get tattooed, with papulonodular and granulomatous reactions being the most common. Some neoplastic complications have been described, but their causality is still debated. Any pigment can cause adverse reactions, although red ink is more frequently associated with them. Patients with pre-existing dermatoses may experience exacerbation or complications of their diseases when getting tattoos; therefore, this procedure is not recommended for this patient group. Conclusions Dermatological consultation is recommended before getting a tattoo, as well as a histopathological examination in case of complications. In patients who develop cutaneous inflammatory reactions following tattooing, additional studies are recommended to investigate systemic diseases such as sarcoidosis, pyoderma gangrenosum, atopic dermatitis, and neoplasms. It is important for physicians to be trained in providing appropriate care in case of complications.
ABSTRACT
Objective To observe the value of augmented reality(AR)navigation system for assisting CT-guided puncture of pulmonary nodules in dog models.Methods Five healthy dogs were selected,and 4 target lung rings were implanted in each dog to build pulmonary nodule models.Deferring to crossover design,CT-guided punctures were performed with or without AR navigation 2 and 4 weeks after successful modeling,respectively,while punctures with AR navigation were regarded as AR group and the others as conventional group,respectively.The time duration of puncturing,the times of CT scanning,of needle adjustment,and the deviation distance between needle pinpoint to the center of pulmonary nodule shown on three-dimensional reconstruction were compared between groups.Results The duration time of puncture in AR group and conventional group was(13.62±5.11)min and(20.16±4.76)min,respectively.In AR group,the times of CT scanning,of needle adjustment,and the deviation distance was 2.40±0.50,2.75±0.44 and(2.94±1.92)mm,respectively,while in conventional group was 3.10±0.64,3.70±0.57 and(4.90±3.38)mm,respectively.The introduction of AR navigation was helpful to shortening the duration of puncture,reducing times of CT scanning and needle adjustment,also decreasing positioning error of needle pinpoint(all P＜0.05).In contrast,the variance of puncture sequences and dogs had no obvious effect on the results(both P＞0.05).Conclusion AR navigation system could improve accuracy and efficiency in CT-guided puncture of pulmonary nodules in dog models.

ABSTRACT
Objective:To investigate the diagnostic value of CT-guided puncture biopsy combined with serum gamma-glutamyltransferase (GGT) and abnormal prothrombin (PIVKA-Ⅱ) in serum alpha-fetoprotein(AFP) negative primary liver cancer (PHC).Methods:Eighty patients with AFP negative PHC treatment in Fuyang Women and Children′s Hospital from January 2018 to March 2021 were selected as AFP negative PHC group, and another 85 patients diagnosed with benign liver tumor during the same period were selected as the control group retrospectively. The patients of the two groups underwent CT-guided biopsy and the levels of GGT and PIVKA-Ⅱ were detected. The single diagnostic value and combined diagnostic value of AFP negative PHC were analyzed by receiver operating characteristic (ROC) curve.Results:Seventy-five of the 80 patients in the AFP negative PHC group were confirmed as liver malignant lesions by biopsy, with a coincidence of 93.75%, and 84 of the 85 patients in the control group were confirmed as liver benign lesions by biopsy, with a coincidence of 98.82%. The levels of AFP, GGT and PIVKA-Ⅱ in AFP negative PHC group were significantly higher than those in the control group: (175.67 ± 39.58) μg/L vs. (18.74 ± 7.42) μg/L, (1 245.37 ± 255.41) U/L vs. (486.63 ± 89.05) U/L, (385.49 ± 30.27) AU/L vs. (25.84 ± 7.66) AU/L, there were statistical differences ( P<0.05). Spearman correlation analysis showed that serum AFP was positively correlated with GGT and PIVKA-Ⅱ ( r = 0.858 and 0.429, P<0.05). The results of ROC curve showed that the area under curve of CT-guided biopsy combined with GGT and PIVKA-Ⅱ in the diagnosis of AFP negative PHC was 0.877, the sensitivity was 91.19%, the specificity was 87.34%. Conclusions:CT-guided biopsy combined with GGT and PIVKA-Ⅱ detection of AFP negative PHC can effectively improve the diagnostic value.
ABSTRACT
Objective:To investigate the clinical efficacy of neuroendoscopic hematoma removal versus soft channel drainage in the treatment of chronic subdural hematoma. Methods:The clinical data of 102 patients with chronic subdural hematoma who received treatment in Jincheng People's Hospital from May 2018 to May 2020 were retrospectively analyzed. They were divided into the neuroendoscopy group ( n = 50) and the soft channel group ( n = 52) according to different surgical methods. Perioperative indexes, hematoma clearance rate, China Stroke Scale score, the activity of daily living score, and oxidative stress indexes were compared between the two groups. All patients were followed up for 3 months. The incidence of complications during the follow-up period was calculated. Results:The retention time of the drainage tube in the neuroendoscopy group was shorter than that in the soft channel group [(2.45 ± 0.63) days vs. (3.30 ± 0.78) days, t = 6.06, P < 0.001]. The length of hospital stay in the neuroendoscopy group was shorter than that in the soft channel group [(7.14 ± 1.65) days vs. (9.07 ± 2.11) days, t = 5.15, P < 0.001]. The hematoma clearance rate at postoperative 7 days in the neuroendoscopy group was higher than that in the soft channel group [(93.45 ± 5.50)% vs. (81.86 ± 7.24)%, χ2 = 9.12, P < 0.001]. There were no significant differences in operation time and intraoperative blood loss between the two groups (both P > 0.05). At postoperative 30 days, the China Stroke Scale score in the neuroendoscopy group was lower than that in the soft channel group [(12.74 ± 2.23) points vs. (18.67 ± 2.45) points, t = 12.79, P < 0.001]. The activity of daily life score in the neuroendoscopy group was significantly higher than that in the soft channel group [(77.69 ± 7.11) points vs. (91.35 ± 7.25) points, t = 9.60, P < 0.001]. At postoperative 7 days, glutathione peroxidase level in the neuroendoscopy group was significantly lower than that in the soft channel group [(130.75 ± 13.66) U/L vs. (148.60 ± 14.64) U/L, t = 6.37, P < 0.001]. Malondialdehyde level in the neuroendoscopy group was significantly lower than that in the soft channel group [(5.11 ± 0.65) nmol/L vs. (6.19 ± 0.74) nmol/L, t = 7.83, P < 0.001]. Superoxide dismutase level in the neuroendoscopy group was significantly higher than that in the soft channel group [(275.60 ± 22.33) U/L vs. (254.60 ± 18.55) U/L, t = 5.15, P < 0.001]. There was no significant difference in the incidence of complications between the two groups ( P > 0.05). Conclusion:Compared with soft channel drainage, neuroendoscopic hematoma removal can obtain better short-term curative effects and less oxidative stress response in the treatment of chronic subdural hematoma. Neuroendoscopic hematoma removal does not increase the incidence of postoperative complications and is highly safe.
ABSTRACT
Objective:To investigate the practicality and safety of performing a radical prostatectomy(RP)shortly after the diagnosis of prostate cancer using a combination of prostate targeted biopsy and intraoperative frozen section.Methods:Prospective enrollment was conducted for patients suspected of having prostate cancer based on abnormal prostate specific antigen(PSA)levels.The inclusion criteria for the study were as follows: patients aged 80 years or younger with an ECOG score of 1 or lower.Prior to biopsy, patients underwent both prostate magnetic resonance imaging(MRI)and prostate specific membrane antigen positron emission tomography/computed tomography(PSMA PET/CT)to determine the likelihood of prostate cancer with clinical stages within T 2-3aN 0M 0.In order to be included in the study, patients must agree to receive RP after their prostate cancer diagnosis has been confirmed by biopsy.All enrolled patients underwent a targeted prostate biopsy, consisting of 1-2 cores.These specimens were then examined through frozen section analysis.For patients diagnosed with prostate cancer through intraoperative frozen section pathology, RP was immediately performed.In this study, transperineal prostate targeted+ systematic biopsy was utilized for patients with undiagnosed prostate cancer.Additionally, routine pathological examination of specimens was conducted.The study analyzed the baseline data, surgical conditions, pathological results, and follow-up information of patients in a descriptive manner. Results:Seven patients, ranging in age from 54 to 77 years with a mean age of 66.7 years, were enrolled in the study.Their mean PSA level was 12.668 μg/L, ranging from 4.359 to 22.195 μg/L.Of these patients, 4 had a PI-RADS score of 4 and 3 had a score of 5.The maximum diameter of the index lesion was 1.3 cm, ranging from 0.5 to 2.2 cm.PSMA PET/CT scores were 4 in 1 case and 5 in 6 cases.The index lesions detected by PSMA PET/CT were consistent with those detected by MRI, and the maximum standardized uptake value(SUVmax)was 15.7, ranging from 5.3 to 39.4.Prostate cancer was diagnosed through targeted biopsy and intraoperative frozen section pathology.Four cases had a Gleason score of 3+ 3=6, while one case had a Gleason score of 3+ 4=7, another had a score of 4+ 3=7, and the last had a score of 4+ 4=8.All patients underwent RP treatment immediately after the prostate cancer diagnosis.Only one patient had slight adhesion at the apex of the prostate, while the other six patients were evaluated by surgeons as having no obvious adhesion at the apex.All surgeries were completed successfully, with a mean operation time of 149.7(ranging from 108 to 255)minutes.After RP, whole mount pathology results indicated that all cases were prostate adenocarcinoma, with a Gleason score of 3+ 4=7 in four cases and 4+ 3=7 in three cases.The pathological stages were pT2 in three cases and pT3a in four cases, with five cases having negative surgical margins and two cases with positive surgical margins.During the study, all patients were monitored for a period of 5.4 months(ranging from 3 to 7 months)and no complications of Clavien Dino≥Ⅰ were observed.PSA levels were measured at 6 weeks and 3 months after surgery, with readings of 0.020 μg/L(ranging from 0 to 0.079 μg/L)and 0.016 μg/L(ranging from 0 to 0.087 μg/L), respectively.No hormonal therapy or radiotherapy was administered during this time.Four patients were able to recover from urinary continence.Conclusions:Based on a combination of MRI and PSMA PET/CT, it is both safe and feasible to promptly perform RP following the diagnosis of prostate cancer through targeted biopsy for index lesions, along with intraoperative frozen section.
ABSTRACT
It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.
ABSTRACT
Objective To compare the principles and performance of three Hough transform algorithms(standard Hough transform,gradient based Hough transform,and random Hough transform)in order to establish a suitable control basis for precise and rapid recognition of targets and acquisition of target center coordinates for craniocerebral puncture robots.Methods A simulation environment in MATLAB software was built to study and analyze image feature recognition,filtering,edge detection,cumulative voting and other processing engineering.Contour recognition and fitting of target circles were achieved in multiple scenarios before their center coordinates were obtained.The recognition and fitting performance of these algorithms was quantitatively compared.Finally,a better detection algorithm based on the actual environment of the craniocerebral puncture robot was determined.Results The standard Hough transform algorithm had the largest error between the mark circle and the target circle,and the running time of this algorithm was the longest due to large computation.The detection speed of the random Hough transform algorithm was lower than that of the gradient-based Hough transform algorithm,but the fitting accuracy was slightly better than that of the standard Hough transform algorithm.The speed and accuracy of circle fitting based on the gradient Hough transform algorithm had significant advantages over the other two.Conclusion The gradient based Hough transform algorithm is more suitable for obtaining the target center coordinates of the craniocerebral puncture robot system.
ABSTRACT
Purpose To assess the feasibility of nuclear score combined with ultrasound features on indeterminate thyroid nodules in fine needle aspiration cytological diagnosis.Methods A consecutive cohort of 119 thyroid fine-needle aspiration(FNA)specimens with indeterminate diagnosis(TBSRTC cate-gory Ⅲ-Ⅴ)and available histopathologic follow-up was evalua-ted.Original sonographic images and cytological slides of each nodule were reviewed by two experienced sonographers and two experienced cytopathologists respectively,and evaluated jointly to obtain consensus.The identification of the optimal cut-off points of simplified nuclear score and ultrasound features score for the diagnosis of malignancy or low-risk neoplasm were evalu-ated using the receiver operating characteristic(ROC)curves and the assessment of the area under the ROC curve(AUC).The specificity,sensitivity,positive predictive value(PPV)and negative predictive value(NPV)of nuclear score and US score were evaluated from crosstabs based on Cut-off points and signif-icance were calculated.The diagnostic accuracy of simplified nuclear score combined with ultrasound features was estimated by Logistic regression and ROC curve analysis.Results Nucle-ar grooves,intra-nuclear inclusions and chromatin clearing were more common in malignancy/low-risk neoplasms(P = 0.001,0.013 and 0.001 respectively).A Cut-off point of≥2 for the simplified nuclear score was sensitive for defining malignancy/low-risk neoplasm,and the sensitivity was 99.1%.Nodule height greater than width,absent halo sign,irregular margin and absent intranodular vascularization were more common in malig-nancy/low-risk neoplasms(P = 0.003,0.007,0.003 and 0.004 respectively).When the Cut-off point was set as≥5,the PPV and specificity for defining malignancy/low-risk neoplasm were 95.9%and 78.6%respectively.ROC curve analysis showed that the diagnostic accuracy of nuclear score combined with US score(0.873,95%CI = 0.777-0.970)was higher than that of nuclear score alone(0.817,95%CI = 0.687-0.948,P =0.092)or US score alone(0.758,95%CI 0.637-0.879,P =0.047).But no significant difference was detec-ted between the combined score and the nuclear score.Conclu-sion The addition of simplified nuclear score and US score to FNA cytology can increase the diagnostic accuracy of cytology in indeterminate categories.
ABSTRACT
Objective:To investigate the clinical effects of stereotactic-guided endoscopic hematoma removal combined with early systematic rehabilitation training on hypertensive intracerebral hemorrhage in the basal ganglia.Methods:A total of 130 patients with hypertensive intracerebral hemorrhage in the basal nucleus who received treatment in Zhejiang Veteran Hospital from June 2019 to December 2021 were included in this randomized control study. They were randomly divided into a control group and a study group ( n = 65 per group). The control group received minimally invasive hematoma puncture. The study group received stereotactic-guided neuroendoscopic hematoma removal. After surgery, early systematic rehabilitation training was carried out, and surgical indicators were recorded. The levels of serum inflammatory factors and stress factors were determined. The recurrence, death, and complications as well as prognosis of cerebral hemorrhage were recorded in each group. Results:The operative time in the study group was (85.39 ± 5.24) minutes, which was significantly longer than (64.17 ± 4.31) minutes in the control group ( t = -14.56, P < 0.001). Hematoma clearance rate in the study group was (94.66 ± 5.18) %, which was significantly higher than (76.82 ± 5.39) % in the control group ( t = -17.63, P < 0.001). At 24 hours after surgery, tumor necrosis factor-α, interleukin-1, norepinephrine, and hydrocortisone levels in the study group were (68.29 ± 5.36) ng/L, (237.62 ± 13.87) ng/L, (75.39 ± 5.82) μg/L, and (30.96 ± 2.97) μg/L, respectively, which were significantly lower than (74.61 ± 5.62) ng/L, (295.47 ± 14.69) ng/L, (91.62 ± 6.41) μg/L, and (38.25 ± 3.16) μg/L in the control group ( t = 7.95, 18.42, 16.84, 11.75, all P < 0.001). There was no significant difference in the 6-month mortality rate between the two groups ( P > 0.05). The recurrence rate of cerebral hemorrhage and the overall incidence of complications in the study group were (1.54% (1/65) and (10.77% (7/65) in the study group, respectively, which were significantly lower than 12.31% (8/65) and 27.69% (18/65) in the control group ( χ2 = 4.30, 5.99, both P < 0.05). The overall excellent and good prognosis rate within 6 months in the study group was 86.15% (56/65), which was significantly higher than 67.69% (44/65) in the control group ( χ2 = 6.24, P < 0.05). Conclusion:Compared with minimally invasive hematoma puncture and drainage surgery, stereotactic-guided neuroendoscopic hematoma removal takes longer time, but it can better effectively increase hematoma removal rate and alleviate stress and inflammatory reactions in patients with hypertensive intracerebral hemorrhage in the basal ganglia. Early systematic rehabilitation training combined with stereotactic guided neuroendoscopic hematoma removal can help reduce the risk of recurrence and complications of cerebral hemorrhage and improve prognosis.

Recurrence of differentiated thyroid cancer (DTC) in the cervix is 5-20% of cases. Fine-needle aspiration cytology of adenopathies has been used to confirm ultrasound findings when suspicions of being malignant. The study aims to evaluate usefulness of fine-needle aspiration of lymph gland to diagnose gland metastases in patients over 18 years old under papillary thyroid cancer follow-up. Retrospective, descriptive and observational study in a 14-patient-sample, mainly female (71,4%), with an average age of 40.9 ± 2.9 years old. Results: single tumor focus papillary thyroid cancer was the most common type of thyroid cancer found. 50% of the 22 suspicious glands had FNATg ≥1ng/ml. All reactive adenitis had measurements < 1ng/ml, whereas metastatic adenopathies results were ≥ 1ng/ml. 85.7% of patients had anti-TG Ac ≥ 1ng/ml (5 patients with FNATg values ≥1ng/ml and 7 patients with FNATg < 1ng/ml), 14.3% of which obtained results < 10 UI/ml (all of them with FN1 ng/ml). Gland emptying was performed in 4 cases, and papillary thyroid cancer metastases was found in all of them. Conclusions: FNATg is a good study to diagnose gland metastases in patients under differentiated thyroid cancer follow-up. Given the results of this study, supported by a bibliographic search, the use of FNATg has a great diagnostic value to detect gland metastases in the follow up of differentiated thyroid cancer, and thus it is recommended along with cytological and/or pathology studies.

Abstract Introduction: There are several approaches for pericardiocentesis. However, there is no definite suggestion about puncture location after cardiac surgery. The purpose of this study is to examine whether there is any difference regarding puncture location during pericardiocentesis in postoperative cardiac tamponade comparing to nonsurgical cardiac tamponade. Methods: We retrospectively analyzed patients who had undergone pericardiocentesis from August 2011 to December 2019. Patients were examined in two groups, nonsurgical and postsurgical, based on the etiology of pericardial tamponade. Clinical profiles, echocardiographic findings, and procedural outcomes were identified and compared. Results: Sixty-eight pericardiocenteses were performed in this period. The etiology of pericardial effusion was cardiac surgery in 27 cases and nonsurgical medical conditions in 41 cases. Baseline demographic variables were similar between the surgical and nonsurgical groups. Loculated effusion was more common in the postsurgical group (48.1% vs. 4.9%, P<0.001). Maximal fluid locations were different between the groups; right ventricular location was more common in the nonsurgical group (36.6% vs. 11.1%, P=0.02), while lateral location was more common in the postsurgical group (12.2% vs. 40.7%, P=0.007). Apical drainage was more frequently performed in the postsurgical group compared to the nonsurgical group (77.8% vs. 53.7%, P=0.044). Conclusion: Apical approach as a puncture location can be used more frequently than subxiphoid approach for effusions occurred after cardiac surgery compared to nonsurgical effusions. Procedural success is prominent in this group and can be the first choice of treatment.
ABSTRACT
Objective:To compare the clinical efficacy of two-dimensional (2D) fluoroscopic guided robot-assisted and conventional TESSYS surgery in the treatment of lumbar disc herniation, the feasibility and precautions of 2D fluoroscopic guided robot-assisted TESSYS surgery were discussed.Methods:A retrospective analysis was performed on 34 male and 36 female patients aged 44.57±6.10 years (range 27 to 60 years) who received 2D guided robot-assisted TESSYS surgery and conventional TESSYS surgery from July 2019 to April 2020. 2D guided robot assisted TESSYS surgery group (the robot group) 32 cases, conventional TESSYS surgery (the conventional group) 38 cases. The number of puncture, number of fluoroscopy, puncture-channel time, operation time, visual analogue scale (VAS) and Oswestry disability index (ODI) before and after surgery and at the last follow-up were compared between the two groups to verify the clinical efficacy, and the complications were analyzed.Results:There were no significant differences in age, gender, body mass index, surgical level, Michigan State University (MSU) grading and average follow-up time between the robot group and the conventional group (all P>0.05). All patients completed surgery. The number of puncture times was 1.22±0.79 in the robot group and 4.66±1.86 in the conventional group, and the difference was statistically significant ( t=10.320, P<0.001). The number of fluoroscopy in the robot group was 10.97±1.96 times, and that in the conventional group was 17.45±4.30 times, the difference was statistically significant ( t=8.313, P<0.001).

ABSTRACT
Objective:To explore the effect of minimally invasive hematoma puncture and drainage in the treatment of elderly patients with cerebral hemorrhage by using 3D slicer and Sina software to conduct 3D reconstruction and preoperative localization of intracerebral hematoma.Methods:A total of 74 elderly patients with a first-onset intracerebral hematoma aged ≥75 years, having surgical indications and stable vital signs were grouped into 3D slicer plus Sina software localization group(as group A, n=40)or CT localization group(as group B, n=34). Based on the localization, hematoma puncture and drainage were performed after local anesthesia.Preoperative preparation time, hematoma location, puncture success rate, postoperative hematoma clearance rate, postoperative re-bleeding rate and GCS score were statistically analyzed.Glasgow coma scale(GCS)scores were used in predicting the mortality.Results:The preoperative preparation time was significantly shorter in group A than in group B[(5.5±3.4)min vs.(8.5±2.7)min, t=3.337, P=0.001]. The success rate of hematoma puncture and drainage(90.0% and 70.6%, χ2=4.51, P=0.034)and postoperative hematoma clearance rate[(87.5±3.4)% and(80.3±2.7)%, t=10.10, P=0.000]were higher in group A than in group B. There were no significant differences in operative time, the accuracy of hematoma localization, re-bleeding rate and GCS score between the two groups( P>0.05). Conclusions:3D slicer plus Sina software can precisely locate the intracerebral hematoma, and minimally invasive hematoma puncture and drainage of intracerebral hematoma under local anesthesia were safe and effective in the treatment of elderly patients with intracerebral hemorrhage.
ABSTRACT
Objective:To investigate the application effect of arteriovenous fistula cannulation by buttonhole technique with blunt needles in patients subjected to hemodialysis.Methods:Seventy-six patients who underwent hemodialysis in Hemodialysis Room, The First Hospital of Jiaxing between June 2016 and June 2019 were included in this study. They were randomly divided into control and observation groups ( n = 38/group). The control group was subjected to arteriovenous fistula cannulation using a regional puncture method. The observation group was subjected to arteriovenous fistula cannulation by buttonhole technique with blunt needles. One-time success rate of puncture was recorded in each group. The maximum transverse diameters of the fistula before and after 6 months of puncture were measured. Severity of pain at the time of puncture was evaluated using Visual Analogue Scale (VAS). Complications were recorded in each group. Patient compliance was investigated using a questionnaire. Patient's quality of life was evaluated using Kidney Disease Quality of Life Short Form 1.3. Results:One-time success rate of puncture in the observation group was significantly higher than that in the control group [97.37% (37/38) vs. 84.21% (32/38), χ2 = 3.93, P = 0.04]. The maximum transverse diameter of the fistula in the observation group was significantly smaller than that in the control group [(4.36 ± 0.11) mm vs. (7.26 ± 0.48) mm, t = 36.30, P < 0.01]. At 6 months after puncture, the maximum transverse diameter of the fistula in each group increased compared with that before puncture (both P < 0.05). The VAS score in the observation group was significantly lower than that in the control group [(0.82 ± 0.24) points vs. (3.11 ± 0.32) points, t = 35.29, P < 0.01]. The incidence of complications in the observation group was significantly lower than that in the control group [5.26% (2/38) vs. 21.05% (8/38), χ2 = 4.15, P = 0.04]. The compliance score in the observation group was significantly higher than that in the control group [(36.32 ± 3.21) points vs. (27.18 ± 2.69) points, t = 13.45, P < 0.01]. The scores of role limitations caused by physical health problems, pain, role limitations caused by emotional health problems in the observation group were significantly lower than those in the control group (all P < 0.05). The scores of physical functioning, general health perceptions, emotional well-being, social functioning, energy/fatigue, and overall health rating item in the observation group were significantly higher than those in the control group (all P < 0.05). Conclusion:Arteriovenous fistula cannulation by buttonhole technique with blunt needles can increase success rate of puncture, reduce pain, decrease the incidence of complications and exhibit protective effects on arteriovenous fistula, thereby improving patient's quality of life and increasing treatment compliance.
ABSTRACT
Objective:To investigate the efficacy of different surgical treatments for hypertensive cerebral hemorrhage in older adult patients and their effects on traumatic stress and cerebral edema.Methods:A total of 100 older adult patients with hypertensive cerebral hemorrhage who received treatment in Zhejiang Xin'an International Hospital from January 2018 to June 2020 were included in this study. They underwent either craniotomy (craniotomy group, n = 50) or hard channel minimally invasive puncture drainage (minimally invasive puncture group, n = 50) according to the willingness of patients and their close relatives. Perioperative indexes, Barthel index after treatment, nerve injury indexes before and after treatment, prognosis related indexes, trauma stress indexes and brain edema were compared between the two groups. Results:Operative time, intraoperative blood loss and postoperative hospital stay in the craniotomy group were (147.21 ± 31.35) minutes, (289.74 ± 22.75) mL and (42.74 ± 6.82 ) days, respectively, which were significantly longer or greater than (41.88 ± 7.19) minutes, (4.62 ± 0.88) mL and (16.27 ± 4.02) days in the minimally invasive puncture group ( t = 38.73, 62.17, 23.17, all P < 0.001). Barthel index at 1 and 3 months after treatment in the minimally invasive puncture group was (63.11± 9.64) and (93.51 ± 11.38), respectively, which was significantly greater than (44.78 ± 8.85) and (81.29 ± 10.37) in the craniotomy group ( t = 3.17, 6.21, both P < 0.05). Before treatment, there were no significant differences in nerve injury index, prognosis index, trauma stress index and brain edema between the two groups (all P > 0.05). At different time points after treatment, each indicator in the minimally invasive puncture group was significantly superior to that in the craniotomy group (all P < 0.05). Conclusion:Hard channel minimally invasive puncture drainage exhibits advantages over traditional craniotomy in the treatment of hypertensive cerebral hemorrhage in older adult patients. Hard channel minimally invasive puncture drainage can more greatly reduce injury to brain tissue, better control nerve injury and brain edema, and more remarkably improve patient's quality of life than traditional craniotomy.
ABSTRACT
Objective:To investigate the clinical efficacy of 3D printed guide plate-assisted hematoma puncture and catheter drainage in the treatment of a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia.Methods:The clinical data of 42 patients with a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia who received treatment with 3D printed guide plate-assisted hematoma puncture and catheter drainage in Dazhu Hospital of North Sichuan Medical College from January 2016 to January 2021 were retrospectively analyzed. In the traditional puncture group, there were 19 patients who received traditional punctures according to preoperative cranial CT findings (traditional puncture group). In the 3D printed guide plate puncture group, there were 23 patients who received hematoma puncture and catheter drainage assisted by a 3D printed guide plate. Preoperative preparation time (from admission to operation), operative time, the number of hematoma punctures, hematoma clearance rate, postoperative indwelling time of drainage tube, residual hematoma rate, the occurrence of puncture canal bleeding, intracranial infection, Glasgow Coma Scale score measured at 3 and 7 days after surgery, and Glasgow Outcome Scale score measured at 1, 3 and 6 months after surgery were compared between the two groups.Results:There were no significant differences in preoperative preparation time and operative time between the two groups ( t = 0.25, 0.40, both P > 0.05). 3D-printed guide plate-assisted hematoma puncture reduced the probability of reveiving one more hematoma puncture during the surgery. There was no significant difference in the number of hematoma puncture between the two groups ( χ2= 0.48, P > 0.05). There were no significant differences in the probabilities of puncture canal bleeding and intracranial infection between the two groups ( χ2 = 0.05, 0.03, both P > 0.05). Postoperative indwelling time of the drainage tube in the 3D printed guide plate puncture group was significantly shorter than that in the traditional puncture group [(3.10 ± 0.38) vs. (3.46 ± 0.52) days, t = 2.65, P < 0.05]. The residual hematoma rate in the 3D printed guide plate puncture group was significantly lower than that in the traditional puncture group [(32.04 ± 5.33)% vs. (37.37 ± 5.51)%, χ2 = 3.20, P < 0.05]. There were significant differences in Glasgow Coma Scale score measured at 3 and 7 days after surgery between the two groups [(12.04 ± 1.19) points vs. (11.26 ± 0.93) points, (13.65 ± 0.88) points vs. (12.94 ± 0.97) points, t = 2.33, 2.46, both P < 0.05]. Glasgow Outcome Scale score measured at 1, 3, and 6 months after surgery in the 3D printed guide plate puncture group was 18, 21, and 22 points, respectively, which was significantly higher than 9, 11, and 12 points in the traditional puncture group ( χ2 = 4.34, 4.69, 5.17, all P < 0.05). Conclusion:3D printed guide plate assisted hematoma puncture and catheter drainage for treatment of a moderate volume of hypertensive intracerebral hemorrhage in the basal ganglia can increase the accuracy of puncture, decrease hematoma residual rate, improve short- and long-term prognosis, does not prolong preoperative preparation time. Moreover, it costs low, is safe, and is easy to learn.
ABSTRACT
Objective:To explore the diagnosis, treatment and prevention of biliary hemorrhage after percutaneous transhepatic choledochoscopic lithotomy(PTCSL).Methods:Retrospective summary and analysis were made on 48 cases of PTCSL completed by the hepatobiliary surgery department of Hunan Provincial People′s Hospital (the First Affiliated Hospital of Hunan Normal University) from January 2016 to December 2020.Results:Biliary hemorrhage occurred in 3 cases after operation, of which 1 case was considered to have a small amount of biliary mucosa bleeding, and the bleeding was stopped after blood transfusion, hemostatic agents and appropriate fluid rehydration. In the other case, a small amount of blood oozing around the T-tube sinus canal was accompanied by a small amount of bloody fluid in the T-tube, which was considered to cause arterioles or venules accompanied by bile duct bleeding during sinus expansion during operation, and the bleeding stopped after compression. Another patient underwent a short time drainage of hemorrhagic fluid ≥100 ml in T tube 15 days after operation, and was prepared for interventional therapy while receiving blood transfusion products and conservative treatment. Celiac arteriography was performed, and pseudoaneurysm was found in the right anterior lobe of the liver. Embolization was performed later and the patient discharged 10 days after embolization.Conclusions:Biliary hemorrhage is one of the more common complications after PTCSL. Increasing the understanding of this complication provides a guarantee for the safety of surgery and has clinical significance for patients with accelerated postoperative recovery.
