ObjectiveTo compare the clinical effects of enteral nutrition via stoma of jejunum or nasal-jejunum tube after Whipple procedure.
MethodsEighty-seven patients performed Whipple procedure were divided into nasaljejunum tube group(n=47)and stoma of jejunum group(n=40)according to the different enteral nutrition methods. The adverse reactions such as vomiting, abdominal distension, pharyngeal pain, and hypostatic pneumonia, anastomotic leakage, hospital stay, hospitalization expenses, and serum glucose and electrolyte(CL-, Na+, K+)on day 1, 3, 5 after operation were compared between two groups.
ResultsCompared with the nasal-jejunum tube group, the rates of adverse reactions and hypostatic pneumonia were more lower(P < 0.05), the hospitalization expense was more less (P < 0.05) in the nasal-jejunum tube group. The rate of anastomotic leakage and hospital stay had no significant differences between the nasal-jejunum tube group and stoma of jejunum group(P > 0.05). The differences of serum glucose and electrolyte(CL-, Na+, K+)on day 1, 3, 5 after operation were not statistically significant between two groups(P > 0.05).
ConclusionsEnteral nutrition via the stoma of jejunum after Whipple procedure has some better clinical effects in reducing adverse reactions such as vomiting, abdominal distension, pharyngeal pain, hypostatic pneumonia. The hospitalization expenses are decreased. There are no obvious effects on the hospital stay, blood glucose and electrolyte concentration on day 1, 3, 5 after operation.
ObjectiveTo evaluate the safety and feasibility of non-nasogastric tube throughout the perioperative period of classical Whipple pancreaticoduodenectomy. MethodsA retrospective analysis was conducted on the clinical data of 63 patients who underwent Whipple pancreaticoduodenectomy at West China Hospital of Sichuan University from June 2020 to August 2023. According to whether nasogastric tube was placed throughout the perioperative period, the patients were divided into nasogastric tube group (NGT group, n=32) and no nasogastric tube group (no NGT group, n=31). The intraoperative indicators such as gastrointestinal anastomosis mode and outcome measures such as postoperative hospital stay were compared between the two groups. Results① Preoperative baseline data: the proportion of benign diseases (P=0.005) and preoperative pancreatitis (P=0.003) of the no NGT group were higher than those of the NGT group, and other preoperative baseline data, such as age and sex, were not statistically significant (P>0.05). ② Intraoperative index: the proportion of circular stapler (P=0.009) was smaller and the operation time was shorter (P<0.001), but there was no significant difference in the anastomosis, intraoperative blood transfusion and intraoperative bleeding (P>0.05). ③ Postoperative outcome measures: the postoperative length of hospital stay (P<0.001) and the incidence of delayed gastric emptying (P<0.001) of the no NGT group were lower than those in the NGT group, but the postoperative time of food intake, incidence of pancreatic fistula, incidence of postoperative bleeding, and Clavien-Dindo grade of complications were not significant (P>0.05), and on one died within 30 d after operation. ConclusionsThe results of this study preliminarily show that, it is safe and feasible not to place nasogastric tubes throughout the perioperativeperiod in patients undergoing classical Whipple pancreaticoduodenectomy. Compared with placing nasogastric tube, it can shorten the postoperative hospital stay, reduce the incidence of postoperative delayed gastric emptying.
Diagnosis and surgical procedures were studied in this paper. Twentyfive cases of insulinoma were treated surgically from 1970 to 1997, in which 10 patients had Whipple′s triad so that the early diagnosis could be made. The sites of tumours were found in 10 out of 12 undergoing. Selective celiac angiongraphy with the accuracy rate of 83%, but B-ultrasonography and CT gave only 10% (4 out of 25) and 40%(8 out of 20) respectively. In this series, 5 cases underwent bodytail pancreatectomy and 20 cases enucleation of insulinoma. Blood glucose levels were tested during operation in 15 cases, and they all reached the normal level one hour after the tumours were completely removed. The authors consider that Whipple′s triad is the main basis in diagnosis of insulinoma. The selective celiac angiongraphy play an important role in detecting and locating the tumour. If diagnosis is made, surgical operation should be taken. The blood glucose monitoring during operation is the hallmark for complete resection of insulinomas.
ObjectiveTo develop an artificial intelligence based three-dimensional (3D) preoperative planning system (AIHIP) for total hip arthroplasty (THA) and verify its accuracy by preliminary clinical application.MethodsThe CT image database consisting of manually segmented CT image series was built up to train the independently developed deep learning neural network. The deep learning neural network and preoperative planning module were assembled within a visual interactive interface—AIHIP. After that, 60 patients (60 hips) with unilateral primary THA between March 2017 and May 2020 were enrolled and divided into two groups. The AIHIP system was applied in the trial group (n=30) and the traditional acetate templating was applied in the control group (n=30). There was no significant difference in age, gender, operative side, and Association Research Circulation Osseous (ARCO) grading between the two groups (P>0.05). The coincidence rate, preoperative and postoperative leg length discrepancy, the difference of bilateral femoral offsets, the difference of bilateral combined offsets of two groups were compared to evaluate the accuracy and efficiency of the AIHIP system.ResultsThe preoperative plan by the AIHIP system was completely realized in 27 patients (90.0%) of the trial group and the acetate templating was completely realized in 17 patients (56.7%) of the control group for the cup, showing significant difference (P<0.05). The preoperative plan by the AIHIP system was completely realized in 25 patients (83.3%) of the trial group and the acetate templating was completely realized in 16 patients (53.3%) of the control group for the stem, showing significant difference (P<0.05). There was no significant difference in the difference of bilateral femoral offsets, the difference of bilateral combined offsets, and the leg length discrepancy between the two groups before operation (P>0.05). The difference of bilateral combined offsets at immediate after operation was significantly less in the trial group than in the control group (t=?2.070, P=0.044); but there was no significant difference in the difference of bilateral femoral offsets and the leg length discrepancy between the two groups (P>0.05).ConclusionCompared with the traditional 2D preoperative plan, the 3D preoperative plan by the AIHIP system is more accurate and detailed, especially in demonstrating the actual anatomical structures. In this study, the working flow of this artificial intelligent preoperative system was illustrated for the first time and preliminarily applied in THA. However, its potential clinical value needs to be discovered by advanced research.
【Abstract】 Objective To evaluate the flexibil ity of the treatment of osteoarthritis secondary to acetabular dysplasiaby total hip arthroplasty (THA) , in which the acetabular component is placed in the true acetabulum and femoral osteotomy is not performed. Methods From January 1999 to December 2005, 35 THA procedures were performed in 32 patients with 35 hips, including 6 males with 7 hips and 26 females with 28 hips, with the average age of 53 years (ranging from 28 years to 72 years). On the basis of Crowe classification, type I included 10 patients with 11 hips, type II included 14 patients with 15 hips, type III included 5 patients with 6 hips, and type IV included 3 patients with 3 hips. All patients experienced severe pain and dysfunction. In 19 cases, the leg length discrepancy was from 3 cm to 6 cm. The Harris score was 41.49 ± 10.13 before the operation. In all procedures, the soft tissue was released entirely and the acetabular component was placed in the true acetabulum, but femoral osteotomy was not performed. Results The average operation time of unilateral THA was 50 minutes. All patients were given transfusion from 2 U to 4 U. All incisions healed at the first stage. After the operation, the leg was lengthened 2-6 cm, and the two legs were equally long. The follow-up lasted for 12 to 60 months. The Harris score was 84.71 ± 9.34 after the operation, showing statistically significant differece (P lt; 0.05). According to cl inical outcomes and X-ray films, no dislocation, femoral fracture, femoral or sciatic nerve palsy was detected. Conclusion It is effective to use THA procedures for osteoarthritis secondary to acetabular dysplasia. If the soft tissue is released entirely, the leg will be lengthened 4-6 cm without nerve palsy.
Objective To investigate the relationship between the initial stabil ity and infected loosening of the total hip arthroplasty (THA) prosthesis. Methods From January 2000 to December 2008, 110 cases (110 hips) were treated with THA revision. Among them, 15 cases (15 hips) were confirmed infected loosening. There were 8 males and 7 females with anaverage age of 62 years (range 42-75 years). The infected signs were found from 6 months to 2 years after initial THA. All of them had Tsukayama type IV and late infection, including 6 cases of acetabular infected loosening (5 cases of one-stage and 1 case of two-stage acetabular revision), 7 cases of simple infected loosening of femoral prosthesis (4 cases of one-stage and 3 cases of twostage femoral prosthesis revision), and 2 cases of joint capsule infection and sinus without prosthesis loosening (debridement and continuous irrigation). Results All incisions healed by first intention. Fifteen patients were followed up for 12 to 36 months (average 24 months). In 13 cases of revision, postoperative X-ray films showed that femoral acetabular prostheses were in good position, and had no cl inical and imaging infective signs of loosening. In 2 cases of joint capsule infection, sinus recurred 6 months postoperation without hip joint pain, the function of weight-bearing and walking of hip joint was normal. Harris score increased from preoperative average of 42 to postoperative average of 85; the results were excellent in 4 cases, good in 7 cases, and fair in 4 cases. Conclusion The infection of THA may occur in the whole joint, half-joint or just in joint capsule. The initial stabil ity of the prosthesis would affect the long-term survival of the prothesis. If the prosthesis initial stabil ity is obtained, even if there are infective factors, infections would also be l imited.
ObjectiveTo explore the clinical outcome of alendronate in the treatment of bone marrow edema syndrome of the hip.MethodsA retrospective analysis of 8 cases (10 hips) of bone marrow edema syndrome of the hip treated with alendronate between December 2017 and January 2020 was conducted. Harris score and MRI exam of hip were used to assess the clinical and radiographical outcomes. Clinical cure rate and length of treatment period were used to evaluate whether alendronate was benefitial for the treatment of bone marrow edema syndrome of the hip.ResultsAll the cases were followed up for at least 3 months and got complete clinical data, the mean follow-up period was (5.2±1.2) months. Seven cases (9 hips) in 8 cases (10 hips) had clinical cure, with a clinical cure rate of 90%. The length of treatment period was 1 to 2 months with a mean value of (1.7±0.2) months. The Harris score increased from 57.8±6.3 before treatment to 98.6±1.0 at the last follow-up, and the difference was statistically significant (t=18.299, P<0.001). One case (1 hip) developed osteonecrosis of femoral head at one month after the initiation of alendronate therapy, who received continuous combination therapy of alendronate, calcium and aspirin, and no collapse or expansion of necrosis was found after 12 months follow-up.ConclusionsBone marrow edema syndrome of the hip is not a self-limiting disease completely, some patients maybe develop osteonecrosis of femoral head. Alendronate is benefitial for alleviating clinical symptom, accelerating bone edema disappearance, and shortening the course of disease.
Objective To analyze the dynamic efficiency of township hospitals. Methods Based on the DEA-Malmquist index, this research analyzed the change of the total factor productivity indices and the decomposition items of 281 township hospitals in Hunan province with panel data from 2000 to 2008. Results Among 281 township hospitals, less than half increased their scale efficiency, while more than half increased their total factor productivity, technology, whole efficiency and technical efficiency. Increasing technology and whole efficiency was the best way to improve total factor productivity. Besides, increasing technical efficiency and scale efficiency was the best way to improve whole efficiency. Conclusions The improvement of scale efficiency is key to developing the central township hospitals, while the improvement of technology is the key to developing general township hospitals.
ObjectiveTo investigate the efficacy of total hip arthroplasty (THA) assisted by the MAKO robotic arm via posterolateral approach.MethodsThe clinical data of 70 patients treated with THA via posterolateral approach between March 2017 and March 2019 who met the selection criteria were retrospectively analyzed. According to different treatment methods, the patients were divided into two groups, 35 were treated with MAKO robotic arm assisted THA (MAKO group) and 35 with traditional THA (THA group). There was no significant difference in gender, age, body mass index, disease duration, etiology, perioperative time, preoperative activity of daily living (ADL) scale index, American Society of Anesthesiologists (ASA) classification, walking ability, comorbidities, hemoglobin, and other general data between the two groups (P>0.05). The operation time, intraoperative blood loss, hospital stay, postoperative acetabular abduction and anteversion angles, postoperative length difference of bilateral lower limbs, and proportions of intraoperative blood transfusion, immediate postoperative loading, wound drainage time more than 2 days, and complications were recorded and compared between the two groups. According to the X-ray films at 6 months after operation, the reduction quality was judged. The forgotten joint score, Harris score, and proportions of independent walking and ADL index increased were used to evaluate the function recovery of patients.ResultsPatients in both groups were followed up 6-18 months, with an average of 8 months. There was no significant difference (P>0.05) between the two groups in operation time, intraoperative blood loss, hospital stay, acetabular abduction and anteversion angles, and length difference of both lower limbs at 6 months after operation. There was no significant difference in the proportions of intraoperative blood transfusion, immediate postoperative loading, and wound drainage time more than 2 days between the two group (P>0.05). X-ray reexamination at 6 months after operation showed that there was no significant difference in the reduction quality between the two groups (Z=4.191, P=0.123). Postoperative complications occurred in 7 patients (20.0%) in the MAKO group and 10 patients (28.6%) in the THA group, showing no significant difference in the incidence of complications between the two groups (χ2=2.121, P=0.224). Two patients (5.7%) in the MAKO group and 4 patients (11.4%) in the THA group underwent revision within 6 months, showing no significant difference in the revision rate between the two groups (χ2=0.729, P=0.673). At 3 and 6 months after operation, the proportions of independent walking and ADL index increased showed no significant difference between the two groups (P>0.05). Harris scores in both groups improved significantly when compared with preoperative scores (P<0.05); there was no significant difference in the forgotten joint scores and Harris scores between the two groups (P>0.05).ConclusionCompared with traditional THA, MAKO robotic arm assisted THA has longer operation time and more intraoperative blood loss, but it has the advantages of accurate positioning and simple operation, and there is no significant difference in short-term postoperative function recovery.
Objective To study the effect of simultaneous bilateral total hip arthroplasty in a single procedure. Methods From October 1999 to March 2004, 15 patients (30 hips) underwent simultaneous sequential bilateral total hip arthroplasty (THAs) in a single procedure. Of the 15 patients, 11 were male (22 hips) and 4 were female (8 hips). Their ages ranged from 35 to 70 years. Their courses of disease ranged from 1 year to 50 years (4.8 years on average). The Harris scores of the joint function before the operation ranged from 12 to 45 points (27 points on average). Five were done with Smith-Peterson and 10 were done with Moore. Results The operative time was 3 hours and 25 minutes to 5 hours (4 hours and 10 minutes on average). The volume of blood transfusion during operation was 400 to 2 400 ml (1 160 mlon average). All the 15 patients were followed up for 3 to 35 months (18 monthson average). The Harris scores of the joint function after the operation rangedfrom 70 to 100 points (86 points on average). There was significant difference in the scores between before and after operations (Plt;0.05). There was only 1death within 1 months of the operation and no serious between complications such as infection, pulmonary embolism, and deep vein plug. All the patients were still ambulant in the community and gained significant pain relief. Conclusion Simultaneous bilateral total hip arthroplasty in a single procedure is a safe and effective method. However, the decision of performing singlestage bilateral total hip arthroplasty should be carefully made and preoperative preparation should be sufficiently made.
