Objective To analyze and explain how to treat 1 patient with post-ERCP hemobilia based on best clinical evidence. Methods We used EST and EPBD, ENBD, Hemobilia as key words to search MEDLINE （1978 ～ 2004） and CBMdisc（1978 ～ 2004） to find the best clinical evidence and evaluated the quality of evidence. Results According to the evidence, we found that endoscopic papillary balloon dilation （EPBD） or endoscopic nasobiliary drainage （ ENBD ） may be more effective and better tolerated in the treatment ofpost-ERCP hemobilia. Our patient did not receive sufficient medical treatment after hemobilia. He was not given a general assessment before surgery including liver function tests. As a result, the patient died of liver failure and its complications. Conclusions We should treat such patients promptly and efficiendy after hemobilia. We should also evaluate their general condition properly before the operation.
Abstract: Objective To summarize the immediate effects and the near and midterm followup results of transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis to find out an effective plan for onestop balloon valvuloplasty. Methods From March 2006 to March 2010, 32 patients including 23 males and 9 females with severe and critical pulmonary valve stenosis were treated in Fu Wai Hospital. Their age ranged from 5 days to 11 months (4.59±3.21 months). Weight of the patients ranged from 2.3 to 10.5 kg (6.48±2.05 kg). Dilatation was performed under general anesthesia with intubation and the guidance of echocardiography. During the follow-up period, all survivors had serial echocardiographic assessment to measure the transpulmonary pressure gradient (TPG) and the degree of pulmonary regurgitation. Results All operations were successful with no severe postoperative complications. Hemodynamic indexes were stable after operation with TPG lowered from from 82±27 mm Hg preoperatively to 23±12 mm Hg postoperatively (t=15.28, Plt;0.05). Only 4 patients had a TPG of more than 40 mm Hg on echocardiography before leaving the hospital. Tricuspid regurgitation was decreased significantly with 17 cases of nonregurgitation, 13 cases of light regurgitation and 2 cases of moderate regurgitation. Saturation of peripheral oxygen in all the patients increased to higher than 95%. Followup time ranged from 1 month to 4 years (16±11 months). The results of the follow-up were satisfying for all the patients. The average TPG was 17±10 mm Hg with only one above 40 mm Hg. Pulmonary valve regurgitation was found in 24 patients including 23 with light pulmonary regurgitation and 1 with moderate regurgitation. Conclusion Transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis is safe and effective.
Objective To investigate the assessment and treatment methods for unilateral spatial agnosia as well as its influence on the functional recovery of patients after stroke, so as to comprehensively understand unilateral spatial agnosia and formulate an effective treatment plan to improve the effect of rehabilitation for stroke patients. Methods A total of 86 patients with unilateral spatial agnosia were analyzed and a pre-treatment and post-treatment comparison was done. Results Of the 86 patients, 21% suffered from unilateral spatial agnosia. The occurrence of unilateral spatial agnosia was related to the location of the stroke lesion. The treatment group witnessed significant improvement after rehabilitation training of correcting unilateral spatial agnosia (Plt;0.05). Conclusion The correct rehabilitation method is beneficial for an early improvement in a patient’s cognitive ability. This also lays a foundation for the recovery of function in their limbs.
ObjectiveTo investigate the effectiveness of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach in treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures. Methods A clinical data of 46 patients with Sanders type Ⅱand Ⅲ calcaneal fractures met the selective criteria between March 2016 and March 2021 was retrospectively analyzed. The factures were fixed with minimally invasive plate and medial supporting cannulated screws via tarsal sinus approach in 20 cases (group A) and with minimally invasive plate in 26 cases (group B). There was no significant difference between groups in term of the gender, age, injury causes, fracture type and side, the time from injury to operation, and preoperative calcaneal length and width, Böhler angle, Gissane angle, and visual analogue scale (VAS) score (P>0.05). The operation time, intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing were recorded. The pain improvement of patients was evaluated by VAS scores before operation and at 48 hours after operation. The ankle joint function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score at 3 and 12 months after operation. Besides, the calcaneal length and width, Böhler angle, and Gissane angle were measured by X-ray films before and after operation. Furthermore, the difference (loss value) between 3, 12 months and 1 day after operation was calculated. Moreover, the fracture healing and healing time was observed. ResultsAll operations of two groups were successfully completed. The incisions healed by first intention, and no vascular/nerve injury or incision infection occurred. The operation time of group A was significantly longer than that of group B (P<0.05). There was no significant difference in the intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing (P>0.05). All patients were followed up 12-36 months (mean, 14.8 months). The VAS scores at 48 hours after operation were significantly lower than those before operation in the two groups (P<0.05); there was no significant difference in the difference of pre- and post-operative VAS score between groups (P>0.05). The AOFAS scores at 12 months after operation were significantly higher than those at 3 months after operation in the two groups (P<0.05); and there was no significant difference between groups at 3 and 12 months (P>0.05). X-ray films showed that the fractures of the two groups healed and there was no significant difference in healing time (P>0.05). There was no significant difference in calcaneal length and width and Gissane angle between groups at each time point (P>0.05), but there was significant difference in Böhler angle between groups at 12 months (P<0.05). The imaging indexes of the two groups significantly improved at each time point after operation when compared with those before operation (P<0.05). There was no significant difference between different time points after operation (P>0.05) in the imaging indexes of group A. There were significant differences in the calcaneal length, calcaneal width, and Gissane angle of group B between 12 months and 1 day, 3 months after operation (P<0.05), and there was no significant difference between 1 day and 3 months after operation (P>0.05). The differences in Böhler angle of group B between different time points after operation were significant (P<0.05). There was no significant difference between groups in the loss of all imaging indexes at 3 months after operation (P>0.05). The losses of calcaneal width, Böhler angle, and Gissane angle in group A at 12 months after operation were significantly smaller than those in group B (P<0.05), and there was no significant difference in the loss of calcaneus length between groups (P>0.05). ConclusionCompared with only minimally invasive plate fixation, the combination of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach for Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of less trauma, less incision complications, reliable fracture reduction and fixation, and good long-term stability.
Objective To investigate the operative indication and clinical efficacy of combination of external fixator and volar approach fixation in treatingdistal radius fracture. Methods From March 2000 to March 2005, 28 patients with distal radius fracture were treated with combination of external fixator and volar approach fixation. Dorsal external fixator was used to maintain wrist in functional position, combinated volar plate or Kirschner wire fixation after reduction was achieved. Bone graft was necessary if there were severe comminuted cortical bone or compress of cancellous bone. Of 28 patients, there were 21 males and 7 females, aging from 1854 years with a median age of 41 years. The locations were the left side in 4 cases and the right side in 24 cases. According to typing criterion for AO, 18 cases were classified as C2 and 10 cases as C3. One case wasaccompanied with dislocation of lunate bone. Results Among 28 patients, 24 were followed up for an average of 8.5 months. The anatomical relationship of their wristjoint were reestablished and retained. Overall good to excellent results were achieved in 87%, excellent in 16 cases, good in 5 cases and fair in 3 cases. Conclusion A combination of external fixator and volar approach fixation is an effective method of treating fractures of the distal radius，because distal radius fracture is unstable or difficult to close reduction. Volarfixation can avoid operative complication, and external fixator can obtain satisfactory reduction and function.

Objective To discuss the main points of technique and the range of fusion in posterior operation of spinal stenosis associated with lumbar degenerative kyphosis (LDK). Methods The cl inical data were retrospectively analysedfrom 20 cases of spinal stenosis associated with LDK which were performed posterior operation from February 2001 to February 2008. There were 1 male and 19 females, aged 52-81 years old with an average of 64 years old. The course of disease was 6-10 years. All patients had severe low back pain. According to Frankel’s neurologic function classification, there were 18 cases of grade E and 2 cases of grade D before operation. The apex of LDK included L1 in 3 cases, L2 in 10 and L3 in 7. The operational method was decided according to different characteristics of LDK. All patients were divided into three groups. Group 1 included 6 cases of sciatica and intermittent claudication with worse physical status, the segmental decompression of spinal canal, posterior intervertebral fusion and short transpedical instrument fixation were performed. Group 2 included 8 cases whose Cobb angle of LDK was less than 20°, the segmental decompression of spinal canal, posterior intervertebral fusion and one-level or multilevel lamina osteotomy were performed, instrumentation-assisted correction was used. Group 3 included 6 cases whose Cobb angle of LDK was more than 20°, the canal decompression and one-level transvertebral wedge osteotomy were performed, instrumentation-assisted correction, intervertebral fusion and posterior-lateral fusion were used. Results Incision healedby first intention in all patients. One patient suffered from superior mesenteric artery syndrome at 6 hours after operationand healed after symptomatic management. The neurologic function was improved to grade E at 2 weeks after opeartion. All patients were followed-up 24-54 months (average 26 months). At last follow-up，the Oswestry Disabil ity Index of all patients was 30.5% ± 9.6%; showing significant difference when compared with preoperation (55.9% ± 11.8%, P lt; 0.05). The back pain scoring and leg pain scoring were 2.8 ± 1.6 and 2.4 ± 1.6, respectively according to the Numeric Rating Scale score; showing significant differences when compared with preoperation (7.5 ± 0.5 and 7.3 ± 0.7, P lt; 0.05). The Numeric Rating Scale score and Oswestry Disabil ity Index in all patients were improved obviously when compared with before operation (P lt; 0.05). During the follow-up period, there was no instrumentation failure or correction loss and the fusion rate was up to 100%. Conclusion For spinal stenosis associated with LDK patients, the most important therapic purpose is to improve cl inical symptom through reconstruction lumbar stabil ization and spinal biomechanics l ine in sagittal plane. Overall estimate of the cl inical appearance and imageology character is necessary when making decision of which segments needed to be fixation and fusion. Individual ized treatment strategy may be the best choice.
【Abstract】 Objective To discuss the main points of techniques and ranges of fusion in posterior operation ofdegenerated lumbar scol iosis compl icated spinal stenosis. Methods From February 2001 to September 2006, 23 cases with degenerated lumbar scol iosis stenosis were treated by posterior operation. There were 9 males and 14 females, with the average age of 65.3 years (ranging from 52 years to 71 years). The course of the diseases was 4 to 8 years. All patients were presented with severe low back pain. All patients were measured for Cobb angle of curves(17° to 53°), and lordosis angle of lumbar (-20° to -10° 10 cases, -40° to -20° 13 cases). Ten cases in which Cobb angle was smaller than 20° were operated by l imited segmental decompression of spinal canal, posterior intervertebral fusion and short transpedical instrument fixation. For the rest 13 cases in which Cobb angle was bigger than 20° were operated by canal decompression, longer instrument for scol iosis correction, intervertebral fusion and posterior-lateral fusion. The fixation and fusion were located at L4-S1 in 6 cases, L1-5 in 5, L2-5 in 4, L1-S1 in 5, L2-S1 in 2 and T10-S1 in 1. Results There was no patient who died from the operation. Average Cobb angle in coronal plane was 0° to 21° with the average of 15.6°. The lumbar lordosis angle was -48.0° to -18.2° with the average of -36.4°. There were 21 cases (91%) with sciatica and intermittent claudication who were clearly released. There were 20 cases (87%) whose low back pain intensely decreased. Three cases with drop-foot returned to normal activities. During the mean 15-month (6 to 54 months) follow-up for 23 cases, there was no change of corrected results and fusion rate was 100%. Conclusion For degenerated lumbar scol iosis patients, the most important purpose of the treatment is to improve cl inical symptoms through sufficient decompression of neural structures. Lumbar stabil ization reconstruction and benign spinal biomechanics l ine conduce to longterm curative effect. Overall estimate of the cl inical appearances and imageology characters is necessary when the decision, that segments are needed to be fixed and fused should be made. The strategy of the individual ized treatment may be the best choice.
The utilisation of statistical analysis plan (SAP) has the potential to enhance the reliability, transparency, and impartiality of statistical analysis procedures in the context of clinical studies. These plans are primarily designed for late phase clinical studies, namely phase Ⅱ and phase Ⅲ randomised controlled trials. The extended SAP reporting guidelines for early phase clinical studies, i.e., phase Ⅰ clinical studies and phase Ⅱ non-randomised controlled trials, have been expanded from the original reporting guidelines in six key areas: trial purpose, design, Bayesian statistics, data simulation, sample size, and the application of ICH E9 (R1). The expanded reporting guidelines facilitate the standardisation of SAP for early phase clinical trials, enhance the transparency and reproducibility of early phase clinical studies, and thereby improve the quality of early phase clinical studies. This, in turn, plays a pivotal role in later phase clinical studies.
ObjectiveTo explore the clinical characteristics and long term mortality of patients with eosinophilic and neutrophilic chronic obstructive pulmonary disease (COPD) exacerbations requiring hospital admission.MethodsA retrospective review of the clinical data and long-term follow up was performed for 510 patients with first diagnosis of acute exacerbation of COPD (AECOPD) requiring hospital admission between January 2015 and December 2016. The follow-up was completed in January 1, 2020. These patients were divided into three groups according to routine blood test: an eosinophilic exacerbation group, with peripheral blood eosinophils >2%; a neutrophilic exacerbation group, with peripheral blood neutrophils >65% or leukocytes >11×109/L; a paucigranulocytic exacerbation group, any case did not belong to the above two groups. The differences of clinical characteristics were compared among three groups. Cox regression model was used for analysis of independent risk factors of all-cause mortality of AECOPD patients.ResultsA total of 510 AECOPD patients were enrolled (180 eosinophilic, 273 neutrophilic and 57 paucigranulocytic, respectively). Compared with the neutrophilic exacerbation group, the eosinophilic exacerbation group had shorter time since onset of symptoms, the lower proportion of comorbid heart failure, the lower proportion of mechanical ventilation, dual antibiotics and systematic corticosteroid treatment, the shorter length of hospitalization and lower hospital mortality (all P<0.05). The average follow-up duration was 41 months for 485 AECOPD patients who completed long term follow-up. Compared with the eosinophilic exacerbation group, the neutrophilic exacerbation group was associated with a higher long-term mortality of AECOPD (HR=1.691, 95%CI 1.205 - 2.373, P=0.002).ConclusionCOPD patients with neutrophilic exacerbations have more serious clinical features and higher mortality than those with eosinophilic exacerbations.
