RESUMO
Objective:To compare and analyze the technical success rate and safety between computed tomography(CT)-percutaneous radiological gastrostomy (PRG) and percutaneous endoscopic gastrostomy (PEG).Methods:From January 2017 to January 2022, at the First Affiliated Hospital of Zhengzhou University, the data of 76 patients who underwent gastrostomy due to inability to eat orally were collected, including 38 patients in PEG group and 38 patients in CT-PRG group. Surgical outcomes and complications were compared between the PEG and CT-PRG groups. Surgical outcomes included technical success rate, operation time, postoperative body mass index and hospital stay; while complications included minor complications (such as perifistula infection, granulation tissue proliferation, leakage, pneumoperitoneum, fistula tube obstruction, fistula tube detachment and persistent pain) and serious complications (such as bleeding, peritonitis, colonic perforation and death within 30 d). Independent sample t test, chi-square test, and Fisher exact probability test were used for statistical analysis. Results:The technical success rate of CT-PRG group was higher than that of the PEG group (100.0%, 38/38 vs. 78.9%, 30/38), and the operation time was shorter than that of the PEG group ((17.16±8.52) min vs. (29.33±16.22) min), and the differences were statistically significant ( χ2=1.19, t=2.36; P=0.038 and 0.011). There were no significant differences in postoperative body mass index ((16.29±3.56) kg/m 2 vs. (16.12±3.17) kg/m 2) and hospital stay ((4.13±1.26) d vs. (3.52±1.13) d) between PEG group and CT-PRG group (both P>0.05). The incidence of minor complications in the PEG group was 42.1% (16/38), including 6 cases of perifistulal infection, 1 case of leakage, 5 cases of fistula tube obstruction, 1 case of fistula tube detachment, and 3 cases of persistent pain. The incidence of serious complications was 5.3% (2/38), including 1 case of bleeding and 1 case of colonic perforation. The incidence of minor complications in the CT-PRG group was 39.5% (15/38), including 5 cases of perifistula infection, 1 case of granulation tissue proliferation, 3 cases of pneumoperitoneum, 3 cases of fistula tube obstruction, 2 cases of fistula tube detachment, and 1 case of persistent pain. The incidence of serious complications was 0. There was no significant difference in the incidence of minor complications between the PEG group and the CT-PRG group ( P>0.05), while the incidence of serious complications in the CT-PRG group was lower than that of the PEG group, and the difference was statistically significant (Fisher exact probability test, P=0.043). Conclusion:PEG is a safe and effective method of gastrostomy, but for patients with esophageal obstruction, CT-PRG can be an effective supplement to PEG.
RESUMO
OBJECTIVE@#To review the application and progress of different minimally invasive spinal decompression in the treatment of lumbar spinal stenosis (LSS).@*METHODS@#The domestic and foreign literature on the application of different minimally invasive spinal decompression in the treatment of LSS was extensively reviewed, and the advantages, disadvantages, and complications of different surgical methods were summarized.@*RESULTS@#At present, minimally invasive spinal decompression mainly includes microscopic bilateral decompression, microendoscopic decompression, percutaneous endoscopic lumbar decompression, unilateral biportal endoscopy, and so on. Compared with traditional open surgery, different minimally invasive spinal decompression techniques can reduce the operation time, intraoperative blood loss, and postoperative pain of patients, thereby reducing hospital stay and saving treatment costs.@*CONCLUSION@#The indications of different minimally invasive spinal decompression are different, but there are certain advantages and disadvantages. When patients have clear surgical indications, individualized treatment plans should be formulated according to the symptoms and signs of patients, combined with imaging manifestations.

【Objective】 To analyze the effect of iliac crest on the difficulty of L5-S1 transforaminal puncture and catheterization by using CT images and oblique sagittal reconstruction images. 【Methods】 We made a retrospective analysis of the CT images and oblique sagittal reconstruction images of the adults aged from 30 to 50 years who underwent abdominopelvic CT examination in Affiliated Hospital of Nantong University. Based on the feasibility of puncture and catheterization， all the subjects were divided into two groups： group Ⅰ （suitable for puncture and catheterization） and group Ⅱ （unsuitable for puncture and catheterization）. We compared and analyzed differences in the rostral puncture inclination angle （α）， the abaxial angle of iliac crest （β）， the distance between the highest iliac crests （a）， the distance between sacroiliac joints （b）， the height of the superior articular process of sacral （c）， the height of iliac crest （d）， and the height of the superior articular process of sacral （c’） in the oblique sagittal images between the two groups. We explored the effect of anatomical indexes and iliac crests in oblique sagittal images on puncture and catheterization. 【Results】 The number of high/low iliac crests for group Ⅰ and group Ⅱ was （117/58 vs. 63/0）， and the number of men/women was 64/111 vs. 56/7， respectively. Variables α， b and c were higher in group Ⅰ than in group Ⅱ （34.77±4.86 vs. 31.11±5.16， P<0.001； 137.19±19.24 vs. 128.56±20.73， P = 0.003； 14.34±2.38 vs. 13.02±2.68， P<0.001）， and d was lower than that in group Ⅱ （27.51±6.73 vs. 37.65±6.35， P<0.001）. In addition， no statistically significant difference was found in the height of c of coronal CT scan and c’ of oblique sagittal reconstruction images （13.99±2.53 vs. 13.93±2.40， P = 0.465）. 【Conclusion】 It is more comprehensive and effective to evaluate preoperatively the influence of iliac crest on L5-S1 puncture and catheterization of TF-PELD by using CT scan and CT 3D reconstruction oblique sagittal images. The key factors in the evaluation of iliac crest are the degree of “cohesion” and the height. It is more easily to successfully puncture and catheterize when the shape of iliac crest is wider and lower. Therefore， it has higher probability to successfully puncture and catheterize in women.
RESUMO
【Objective】 To compare the anesthestic effects of ultrasound-guided retrolaminal block （RLB） and local anesthesia during posterior approach vertebral surgery. 【Methods】 Forty patients （ASA physical status Ⅰ or Ⅱ） scheduled for transforaminal lumbar spine endoscopic surgery were recruited and randomly divided into two groups （n=20）： RLB group and local anesthesia group （Group C）. RLB group received the ultrasound-guided retrolaminar block using parasagittal in plane method by an anesthesiologist while Group C received layer-by-layer local infiltration anesthesia according to the operation location； 0.5% ropivacaine of 20 mL was used in the two groups. We recorded visual analogue score （VAS） and Ramsay sedation score at admission （T0）， during skin incision （T1）， puncture （T2）， foraminoplasty （T3）， nerve root decompression （T4） and suture （T5）. We also recorded remedial analgesia rate， scores of the patients’ satisfaction and the intraoperative occurrence of side effects （respiratory depression， tachycardia and hypertension）. The patients were followed up. Their functional status was assessed by the Oswestry Disability Index （ODI） score before surgery and three months after surgery. 【Results】 Compared with Group C， RLB group had significantly decreased visual analogue score at T2-4 and lower remedial analgesia rate （P<0.05）. The patients’ satisfaction was higher in group RLB than in Group C （P<0.05）. The intraoperative occurrence of hypertension and tachycardia were significantly lower in RLB group than in Group C （P<0.05）. ODI score was significantly decreased three months after surgery in both groups （P<0.05）， but it did not differ significantly between the two groups （P>0.05）. 【Conclusion】 Ultrasound-guided RLB can provide satisfactory analgesia with greater safety when trasforaminal endoscopic surgery is used.
RESUMO
【Objective】 To compare the perioperative blood loss between interlaminar and transforaminal approaches by percutaneous endoscopic discectomy in order to provide more reference for guiding the proper choice of surgical methods clinically. 【Methods】 We retrospectively analyzed the clinical data of 160 patients who underwent percutaneous endoscopic lumbar discectomy from June 2019 to November 2020， with 80 patients in interlaminar approach group and 80 in transforaminal approach group. The blood loss was calculated according to Gross formula. 【Results】 The perioperative total blood loss （mL）， hidden blood loss （mL） and hemoglobin loss （g/L） were significantly lower in interlaminar approach group than in transforaminal approach group （119.73±179.26 vs. 158.6±190.65， 109.73±179.53 vs. 148.78±190.19， 3.76±8.12 vs. 4.31±7.62） （P<0.05）. However， there was no significant difference in visible blood loss between the two groups. 【Conclusion】 The perioperative hidden blood loss accounts for a large proportion in percutaneous endoscopic lumbar discectomy. In addition， the interlaminar approach causes less blood loss than the transforaminal approach.
RESUMO
【Objective】 To observe the short-term clinical effect of selective nerve block combined with percutaneous posterior endoscopic cervical discectomy （PPECD） in the treatment of cervical spondylotic radiculopathy. 【Methods】 We reviewed 22 patients who received selective nerve block combined with percutaneous posterior endoscopic cervical discectomy （PPECD） for cervical spondylotic radiculopathy from June 2018 to January 2020. We recorded Japanese Orthopaedic Association （JOA） score for treatment evaluation， visual analogue scale （VAS）， the neck disability index score （NDI） preoperative 1 day， postoperative 1 day， 1 month， 3 months， 6 months and 1 year. All data were imported into SPSS26.0 software for analysis and processing. Quantitative data are expressed as mean ± standard deviation. The scores of neck VAS， arm VAS， JOA and NDI were compared at different time points by repeated measurement analysis of variance. Paired t-test was used to compare each time point after operation and the first day before operation. P<0.05 was considered statistically significant， and the modified MacNab standard was used to evaluate the clinical effect at the last follow-up. 【Results】 All operations were successfully completed under ultrasound-guided selective nerve block combined with endoscopic operation. The average operation time was 125.6 minutes. The intraoperative blood loss was 2-100 mL and the average blood loss was 19.1 mL. All patients were followed up for 15-33 months， with an average follow-up of 24.1 months. No patients had spinal cord， nerve root and vascular injury， dural tear or other complications. Compared with the preoperative VAS score， the VAS score of neck and upper arm decreased significantly （P<0.05）， while the JOA score increased significantly （P<0.05）， and the preoperative NDI score decreased significantly （P<0.05）. At the last follow-up， the modified Macnab criteria showed there were 15 excellent cases， 5 good cases， 2 medium cases and 0 poor case. The excellence rate was 91%. Postoperative magnetic resonance imaging and 3D computed tomography reconstruction of the cervical spine showed that the disc had been fully removed and the nerve root compression at the surgical segment was relieved. 【Conclusion】 Ultrasound-guided selective nerve block combined with percutaneous posterior endoscopic cervical discectomy is a safe and effective minimally invasive surgical method for the treatment of cervical spondylotic radiculopathy with reliable short-term efficacy.
RESUMO
Objective:To evaluate the efficacy of transgastric combined with percutaneous endoscopic treatment for infected pancreatic necrosis (IPN).Methods:Clinical data of 19 IPN patients who received transgastric combined with percutaneous endoscopy at the Gastroenterology Intensive Care Unit of Nanjing Drum Tower Hospital from August 2015 to August 2020 were retrospectively studied. The clinical efficacy and the procedure-related complications were analyzed.Results:The mean procedure of endoscopic transmural drainage (ETD) was 1.1±0.3 times. During ETD procedure, lumen-apposing metal stents (LAMS) were placed in 9 patients, metal coated stents in 2 patients, double pigtail plastic stents in 7 patients, and only a nasal cyst drainage tube in 1 patient. All 19 patients received 12-14 F drainage catheters for drainage during the first percutaneous catheter drainage (PCD) treatment with the mean number of catheters of 1.8±1.2. Double cannulas was subsequently replaced in 3 of them for continuous drainage, and a percutaneous metal coated stent was replaced in 1 patient. The culture results of drainage fluid were 11 cases of gram-negative bacilli and gram-positive cocci, 4 cases of gram-positive cocci, 1 case of gram-positive bacilli, 3 cases of gram-negative bacilli. Among 19 patients, 4 cases had concurrent fungal infections. The mean number of debridement was 3.1±1.8 times, 2 cases of which were treated with endoscopic transluminal necrosectomy combined with percutaneous endoscopic necrosectomy. The mean procedure per patient was 6.1±2.4 times. Bleeding occurred in 1 case (5.3%) after the operation. But the bleeding was successfully stopped after endoscopic hemostasis. No serious complications such as gastrointestinal fistula, perforation or pancreatic fistula occurred. One patient died due to sepsis, and 18 other patients showed significant absorption of IPN after the treatment. None of the 19 patients were transferred to laparotomy.Conclusion:Transgastric combined with percutaneous endoscopic approach is safe and effective for IPN.
RESUMO
ABSTRACT BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is an important option for enteral nutrition for both children and adults. It is considered a safe, effective, and advantageous technique in comparison to other complementary feeding routes. It allows continuous feeding, the feeding of patients with swallowing disorders due to neurological causes or others, and the administration of non-palatable diets or medications, all with low rates of complications and mortality. OBJECTIVE: This study aimed to evaluate the main indications and complications of PEG in pediatric patients. In addition, the impact on the nutritional status of patients undergoing PEG was also compared with weight, body mass index (BMI), and height according to references from the World Health Organization. METHODS: This observational and retrospective study included 152 children and adolescents who underwent PEG between January/2003 and December/2018. Patients up to 18 years of age at the time of the procedure were included. Complications related to the procedure were classified as minor or major. Patients with PEG indication for nutritional supplementation were evaluated for weight gain, height, and BMI, using the Z score at the day of the procedure and six months, 1 year, and 2 years after the procedure. RESULTS: Indications for PEG were: swallowing disorder of neurological cause (67.1%), need for nutritional supplementation (25%), swallowing disorder of mechanical origin (6.6%), and indication of gastric decompression (1.3%). Minor complications occurred in 57.8% of patients and major complications in 9.8% of patients. The traction technique corresponded to 92.1% and puncture to 7.9%. The death rate was 1.3%. Thirty-eight patients had an indication for nutritional supplementation. In these patients, there was a gradual increase in both BMI and weight, reaching statistically significant differences (P=0.0340 and P= 0.0105, respectively). These differences were more evident in chronic renal disease patients. Height did not vary significantly (P=0.543). CONCLUSION: PEG proved to be an advantageous option as an auxiliary feeding method in pediatric patients. Dysphagia of neurological origin was the main indication followed by the need for nutritional supplementation. PEG has low frequency of major complications and mortality. This study also showed the importance of PEG in patients who need nutritional supplementation, as it enabled patients to move from undernutrition to normal weight ranges.
RESUMO CONTEXTO: A gastrostomia endoscópica percutânea (GEP) é uma importante opção de nutrição enteral para crianças e adultos, sendo considerada uma técnica segura, eficaz e vantajosa em comparação às outras vias de alimentação complementar. Permite a alimentação contínua, a alimentação em pacientes com distúrbios de deglutição de causa neurológica ou outros, a administração de dietas ou medicamentos não palatáveis, todos com baixos índices de complicações e mortalidade. OBJETIVO: Avaliar as principais indicações e complicações de pacientes pediátricos submetidos à GEP e o impacto no estado nutricional de pacientes submetidos à GEP para suplementação nutricional, comparando peso, índice de massa corporal (IMC) e estatura com referências da Organização Mundial de Saúde. MÉTODOS: Estudo observacional e retrospectivo de 152 crianças e adolescentes submetidos à GEP, no período de janeiro/2003 a dezembro/2018. Foram incluídos pacientes até 18 anos de idade na época do procedimento. As complicações relacionadas ao procedimento foram divididas em menores e maiores. Pacientes com indicação de GEP para suplementação nutricional foram avaliados quanto ao ganho de peso, altura e IMC, por meio do escore Z no dia do procedimento e 6 meses; 1 ano; e 2 anos após o procedimento. RESULTADOS: As indicações para GEP foram distúrbio de deglutição de causa neurológica (67,1%), necessidade de suplementação nutricional (25%), distúrbio de deglutição de origem mecânica (6,6%), e indicação de descompressão gástrica (1,3%). Complicações menores ocorreram em 57,8% dos pacientes e complicações maiores em 9,8%. A técnica de tração correspondeu a 92,1% e a punção, 7,9%. A taxa de mortalidade foi de 1,3%. Trinta e oito pacientes tinham indicação de suplementação nutricional. Nestes, houve aumento gradativo tanto do IMC quanto do peso, com variação estatisticamente significativa da mediana P=0,0340 e P=0,0105, respectivamente, mais evidente nos pacientes renais crônicos. A altura não variou significativamente (P=0,543). CONCLUSÃO: A GEP mostrou-se uma opção vantajosa como forma auxiliar de alimentação em pacientes pediátricos, tendo como principais indicações a disfagia de causa neurológica e a necessidade de suplementação nutricional, com baixa prevalência de complicações maiores e mortalidade. Este estudo também mostrou a importância da GEP em pacientes com necessidade de suplementação nutricional, possibilitando a passagem dos pacientes desnutridos para escores nutricionais de peso adequados à idade.

【Objective】 To explore the establishment of individualized prediction model of recurrence after percutaneous endoscopic lumbar discectomy （PELD） in patients with lumbar disc herniation （LDH）. 【Methods】 We selected 124 LDH patients treated with PELD in Department of Orthopedics， The First Affiliated Hospital of Xi’an Jiaotong University， from January 2017 to January 2020 as the research subjects. Their clinical data were retrospectively analyzed， and the independent risk factors affecting PELD recurrence in the LDH patients were screened by univariate analysis and Logistic regression analysis， respectively； the correlation histogram prediction model was established. 【Results】 Age， history of diabetes， course of disease， work intensity and IDDG were the risk factors for the recurrence of PELD in LDH patients （P<0.05）. Based on the risk factors screened out， the prediction model of the histogram was established， and the model was verified. The results showed that the C-index of the modeling set and the validation set was 0.944 （95% CI： 0.902-0.963） and 0.969 （95% CI： 0.911-0.978）， respectively. The correction curves of both groups were well fitted with the standard curves. The areas under the ROC curve （AUC） in the two groups were 0.944 and 0.969， respectively， which proved that the model had good prediction accuracy. 【Conclusion】 LDH patients have many independent risk factors for recurrence after PELD， and the model based on risk factors with good predictive ability can be useful in preoperative evaluation， appropriate patient selection， and decrease of recurrence rate after PELD.

Objective: To identify effect of quantitative indicators of ilium height on approach of percutaneous endoscopic lumbar discectomy (PELD) treatment in patients with L 5, S 1 lumbar disc herniation. Methods: A retrospective study between May 2014 and March 2016 was conducted, including 100 patients with disc herniation at L 5, S 1, who were initially enrolled for the PELD treatment. Among them, 66 patients were successfully treated with PELD (group A), and the other 34 patients failed to perform puncture, catheterization, or microscopical operation due to the influence of iliac bone and other peripheral bone structures and treated with alternative surgical plans. By analyzing the X-ray films of lumbar vertebrae (including bilateral ilium) of the two groups before operation, the concept of ilium height rate and ilium angle rate was put forward innovatively. The ilium height rate and ilium angle rate of the two groups were measured and compared, and the diagnostic critical points of ilium height rate and ilium angle rate were determined by ROC curve analysis. Results: The ilium height rate was 0.61±0.09, 0.74±0.05 and the ilium angle rate was 0.66±0.08, 0.80±0.08 in groups A and B, respectively, showing significant differences between the two groups ( F=69.729, P=0.000; F=65.165, P=0.000). ROC curve analysis showed that the critical point of ilium height rate was 0.71 (area under ROC curve was 0.927, P=0.000), and the critical point of ilium angle rate was 0.75 (area under ROC curve was 0.965, P=0.000). Conclusion: PELD is not recommended for patients with L 5, S 1 intervertebral disc herniation, when the ilium height rate is greater than 0.71 and/or the ilium angle rate is greater than 0.75. Other surgical plans such as transpedicular approach, transpedicular approach, or open surgery, should be recommended to reduce the risk of surgery and the pain of patients.
RESUMO
BACKGROUND: At present, there are many surgical methods for the treatment of lumbar disc herniation, and the therapeutic effects have their own advantages. Although there are many meta-analyses to compare the therapeutic effects of the two surgical methods, there is no comparison of the therapeutic effects of several surgical methods. OBJECTIVE: To compare the differences of different surgical methods in the treatment of lumbar disc herniation by network meta-analysis. METHODS: PubMed, Embase, Cochrane Library, Ovid and CNKI were searched, and randomized controlled trials or retrospective studies on different surgical methods for the treatment of lumbar disc herniation were collected. According to the inclusion and exclusion criteria established in advance, the quality of included randomized controlled trials was evaluated, and the data were analyzed by STATA 15.0 software. RESULTS AND CONCLUSION: A total of 42 studies, 5 156 patients and 9 surgical treatments were included. Surgical treatments contain total disc replacement, lumbar disc fusion, standard open discectomy, microendoscopic discectomy, microdiscectomy, percutaneous endoscopic lumbar discectomy, chemonucleolysis, automatic percutaneous lumbar discectomy and percutaneous laser disc decompression. The results of network meta-analysis showed that(from best to worst):(1) There was no significant difference in leg pain relief, and the rank probability was percutaneous laser disc decompression > microendoscopic discectomy > percutaneous endoscopic lumbar discectomy > standard open discectomy > microdiscectomy > lumbar disc fusion > total disc replacement.(2) There was no significant difference in low back pain relief, and the rank probability was total disc replacement > lumbar disc fusion > microendoscopic discectomy > percutaneous endoscopic lumbar discectomy > microdiscectomy > percutaneous laser disc decompression > standard open discectomy.(3) There was no significant difference in Oswestry disability index scores, and the rank probability was microendoscopic discectomy > percutaneous endoscopic lumbar discectomy > standard open discectomy > microdiscectomy > total disc replacement > lumbar disc fusion.(4) There were some statistical differences in the success rate, and the rank probability was total disc replacement > lumbar disc fusion > microendoscopic discectomy > percutaneous endoscopic lumbar discectomy > standard open discectomy > percutaneous laser disc decompression > microdiscectomy > chemonucleolysis > automatic percutaneous lumbar discectomy.(5) There was no significant difference in reoperation rate, and the rank probability was total disc replacement > lumbar disc fusion > microdiscectomy > microendoscopic discectomy > standard open discectomy > percutaneous endoscopic lumbar discectomy > percutaneous laser disc decompression > chemonucleolysis > automatic percutaneous lumbar discectomy.(6) There were some statistical differences in incidence of complications, and the rank probability was percutaneous endoscopic lumbar discectomy > automatic percutaneous lumbar discectomy > standard open discectomy > microdiscectomy > percutaneous laser disc decompression > microendoscopic discectomy > total disc replacement > lumbar disc fusion > chemonucleolysis. Results suggested that microendoscopic discectomy and percutaneous endoscopic lumbar discectomy are effective in all aspects. Disc replacement and lumbar disc fusion are the best in success rate of operation. Chemonucleolysis is poor in success rate of operation, reoperation rate and complications rate. Percutaneous automatic discectomy is poor in success rate of operation and reoperation rate.
RESUMO
OBJECTIVE@#To analyze the clinical effects, complications and operational key points of the percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) in treating LS disc herniation.@*METHODS@#The clinical data of 158 patients with L5S1 disc herniation treated from July 2015 to March 2018 were restospectively analyzed. According to different surgical approaches, the patients were divided into PETD group or PEID group, 79 cases in each group. In PETD group, there were 41 males and 38 females, with an average age of (41.38±6.25) years and course of disease of (10.06±3.14) months. In PEID group, there were 43 males and 36 females, with an average age of (41.18±5.78) years and course of disease of (9.99±2.83) months. The operation length, intraoperative blood loss, intraoperative fluoroscopy times, days of hospital stay, and complications were recorded between two groups. Visual analogue score (VAS), Japanese Orthopedic Association(JOA) score, Oswestry Disability Index(ODI), modified Macnab criteria were used to assessed clinical effects after operation.@*RESULTS@#All patients completed surgery and were followed up for more than 1 year. (1) There were no significant differences in the intraoperative blood loss or hospitalization length between two groups(>0.05). The operation length and intraoperative fluoroscopy times in PETD group were significantly higher than in PEID group (0.05). (3)The excellence rate was 89.87% (71 / 79) in PETD group and 87.34% (69 / 79) in PEID group at the latest follow-up, with no statistical significance(>0.05). (4)Complications occurred in 2 cases in PETD group and in 3 cases in PEID group, with no significant differences between two groups.@*CONCLUSION@#The short term efficacy of the PETD is equal to that of the PEID for the LS disc herniation, but PEID is superior in the operation length, the access of stereotaxic puncture and intraoperative fluoroscopy times. The complications can be effectively reduced by following the indications, mastering the endoscopic technique, operating carefully and being familiar with the key points of common complications.

People's understanding of lumbar spinal stenosis has become more and more comprehensive and reasonable, however, there are still many controversies about the concepts of "central lumbar canal" and "lateral lumbar spinal canal", and there is no unified standard at present. In this paper, we redefine and differentiate the two concepts. We believe that some kinds of central canal stenosis caused by bilateral recess stenosis can be completely solved by bilateral percutaneous endoscopic transforaminal discectomy. At the same time, the concept of "lumbar lateral recess" is ambiguous. We redefine it as "lateral lumbar spinal canal" and propose "West China Hospital classification" to guide surgical decision-making, which has been widely recognized and applied.
RESUMO
Objective@#To investigate the feasibility and safety of stent-assisted percutaneous endoscopic necrosectomy (SAPEN) in the treatment of infected pancreatic necrosis (IPN).@*Methods@#The patients with severe acute pancreatitis (SAP) who received the treatment of SAPEN for IPN were sequentially included from January 2018 to September 2018 in the Eastern Theater General Hospital of People′s Liberation Army. The demographic and clinical data were analyzed. The mortality and incidence of major organ dysfunctions were used as the primary observation endpoints.@*Results@#A total of 40 IPN patients were enrolled including 27 men and 13 women. The percutaneous covered stent placement procedures were successful in all cases; the median number of SAPEN operations was 1 (range 1-3), and no operation-related complications occurred. 32 patients were successfully cured by SAPEN, and the treatment effective rate was 80.0%. 5 patients (12.5%) required further open surgery after SAPEN. 12 patients developed new important organ dysfunction and 6 patients eventually died.@*Conclusions@#SAPEN was an effective and feasible minimally invasive method for the treatment of IPN, but its technical advantages still need to be further validated in large scale studies.
RESUMO
Percutaneous endoscopic gastrostomy (PEG) and percutaneous endoscopic Jejunostomy (PEJ) are common channels for enteral nutrition input. In the past five years, there are no relevant nursing guidelines and reviews in China. In August 2018, Wound, Ostomy and Continence Nurses Society (WOCN) issued the Clinical Practice Guidelines for Nursing Management of Percutaneous Endoscopic Gastrostomy and Jejunostomy in Adults, including preoperative preparation, surgical procedure and postoperative monitoring of gastrostomy and Jejunostomy. The management of enteral nutrition tube, the use of enteral nutrition and drugs, the prevention of medication errors, the treatment of early and late complications, the education of patients and their caregivers, and the replacement of catheters are all recommended. This article interpreted the guideline in order to provide reference for clinical nursing of gastrostomy and Jejunostomy.

RESUMO
Continuous duodenal levodopa/carbidopa intestinal gel delivery by a gastrostomy infusion system improves control of Parkinson’s disease. The overall complication rates of percutaneous endoscopic gastrojejunostomy were reported to be 41% and 59% for immediate and delayed adverse events, respectively. A 72-year-old woman underwent percutaneous endoscopic gastrojejunostomy using the delivery system noted above. Abdominal pain and vomiting occurred 3 months later. Esophagogastroduodenoscopy showed a longitudinal ulcer extending from the lower gastric body to the ileum end, with small intestinal telescoping. Colonoscopy showed a large bezoar of food residue that was attached around the tip of the tube, reaching the ascending colon, which may have acted as an anchor. Thus, the gastric antrum and small intestine were shortened with telescoping. This complication was resolved by crushing the bezoar with forceps during colonoscopy and can be prevented by consuming a fiber-free diet and periodic exchanges of the tube using esophagogastroduodenoscopy.
