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.
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 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.
Objective To compare the bone resorption between the proximal fixation of the anatomique benoist giraud（ABG） hip and the distal fixation of the anatomic medullary locking（AML） hip by the medium-term X-ray films, and to evaluate the clinical results of the two prostheses. Methods From January 1992 to December 1996, 298 patients (396 hips) underwent the total hip arthroplasty at Wilson Hospital in Korea. In 125 patients, 176 hips were ABG hips, including 103 avascularnecrosis hips, 57 dysplasia hips, and 16 other diseased hips; In the other 173 patient the remaining 220 hips were AML hips, including 147 avascular necrosis hips, 65 dysplasia hips, and 8 other diseased hips. The A-P X-ray imagings were followed up for 5-12 years averaged 8 years, and were compared with the immediate postoperative X-ray imagings. The bone resorption area was measured and the bone resorption cases were recorded according to the Gruen zone obsesvation. Results During operation, 2 ABG hips and 5 AML hips were cracked at the femoral diaphysis; 3 ABG hips and 1 AML hip were cracked at the metaphysis; 6 ABGhips and 3 AML hips were fractured because of trauma after operation; among them, 2 ABG hips needed the stem revision and the remaining hips underwent the openreduction and the internal fixation. During the follow-up, 9 ABG hips were revised, 7 hips of which developed the aseptic loosening. No AML hip was revised, but 3 AML hips developed the aseptic loosening. The bone resorption pattern in theABG and AML hips was similar. The bone resorption occurred most commonly in theGruen zones 1 and 7, and it extended from the metaphysis to the diaphysis. In the Guren zones 2, 5, 6 and 7, there were more AML hips than ABG hips that developed the bone resorption. The bone resorption area around the AML hip was larger than that around the ABG hip. Conclusion The stress shielding bone resorption usually occurs proximally to the union area of the bone and the prosthesis. The ABG prosthesis is a proximal fixation prosthesis, therefore, the stress shielding bone resorption can be reduced. The bone resorption around the AML prosthesis develops slowly within 10 years after operation. The stress shielding bone resoption may reach the summit within 10 years and it will not develop endlessly, so the prosthesis will be stable for a long time. The probabilityof the bone resorption in the ABG prosthesis is smaller than that in the AMLprosthesis. The bone resorption around the AML prosthesis may develop slowly after 10 years and will not affect the stability of the prosthesis for a long time.
Objective To evaluate the effectiveness of the shared decision-making scheme in postoperative out-of-hospital extended care for patients with total hip/knee arthroplasty (THA/TKA). Methods Patients who underwent THA/TKA in the Department of Orthopedic Surgery at West China Hospital of Sichuan University between October 2023 and April 2024 were included using convenience sampling. Patients were divided into the control group (odd-numbered dates) and the intervention group (even-numbered dates) based on the surgical dates. The intervention group was received care guided by a shared decision-making protocol, whereas the control group was followed the standard post-arthroplasty follow-up procedures. Differences between the two groups were compared in terms of decision-making capacity, decision satisfaction, and hip/knee function at the following time points: on the day of discharge, 3 weeks after discharge, 2 months after discharge, and 3 months after discharge. Results A total of 118 patients were included, with 59 cases in each group. There were no significant differences in demographic and clinical characteristics between the two groups (P>0.05). In terms of decision-making, compared with the control group, the experimental group had stronger decision-making ability, lower decision-making conflict, and more satisfaction with the decision-making process (P<0.05). In terms of joint function, the experimental group showed better joint function than the control group at 3 weeks, 2 months, and 3 months after surgery (P<0.05). There was no significant difference in the pain dimension of the Western Ontario and McMaster Universities Osteoarthritis index between the two groups (P=0.199). Conclusions Compared with the traditional follow-up protocol, the shared decision-making protocol can enhance patient engagement in medical decision-making, reduce decisional conflict, improve satisfaction with the decision-making process, and simultaneously promote joint functional recovery and expedite the rehabilitation process.
Objective To identify genes associated with hepatocellular carcinoma (HCC) as candidate diagnostic markers in a genome-wide scale. Methods The gene expression profiles of 40 pairs of HCC tumor tissue and peripheral non-tumorous liver tissue were analyzed by using gene chip technology.The gene chips were fabricated at the National Cancer Institute (NCI). Each gene chip contained 9 180 genes. The fluorescent targets were prepared by a direct labeling approach using two kinds of fluorescences as following: 100 μg of total RNA from non-cancerous liver tissue was labeled with Cy3-dUTP and 200 μg of total RNA from HCC was labeled with Cy5-dUTP. The targets were mixed together and hybridized with genes on the gene chips. Unsupervised hierarchical clustering analysis was done by CLUSTER and TREEVIEW software using median centered correlation and complete linkage. Results A total of 10 genes were found up-regulated in over 80% of primary tumors comparing with that of their corresponding non-tumorous liver tissues at a two-fold filter with an unsupervised hierarchical clustering algorithm, including protocadherin-alpha 9, ESTs, Homo sapiens cDNA FLJ, KPNA2, RPS20, SNRPE, CDKN2A, UBD, MDK and ANXA2.Conclusion These genes are supposed to be candidates for the diagnosis of HCC. Further investigation of these genes in a large scale of patients with HCC and patients with non-malignant hepatic diseases will be needed to disclose whether they could be used clinically as novel diagnostic tumor markers for HCC.
Objective To find a more perfect method of treating developmental dislocation of the hip(DDH). Methods From March 1994 toDecember 2002, on the basis of the ordinary operative method, Pemberton method was improved for 48 cases of DDH 49 articulatio coxae which had superficial and small acetabula but bigheads of femur. Osteotomy points were moved higher to enlarge area of bone flapturned over. A piece of full thickness ilium including periosteum was removed as a free bony graft. Capsula articularis growing thicker was made into 2 layers, of which the inner layer was used to tighten articularis and the outer layerwas used to stabilize bone flap. Results All patients were followed up for 18 months to 5 years, the function of articulatio coxae and degree of bony union, inclusion area to head of femur and ischemic necrosis of femoral head were observed through X-ray. According to Zhou Yongde’s criteria for the curative effect of congenital dislocation of the hip, there were 18 cases of 26-30 scores(3 hips), 27 cases of 21-25 scores, 2 cases of 1620 scores(3 hips), and 1 case under 15 scores, and the total superior ratewas 93.8%. Conclusion Improved Pemberton method can enlarge inclusion area tohead of femur, avoid decreasing acetabular volume, and stabilize articulatio well, which made operative indication bigger than original Pemberton method.
【Abstract】 Objective Through a retrospective study, to observe the cl inical therapeutic effect for closed reductiontreatment of developmental dislocation of the hip (DDH), and to dynamically analyze characteristics of acetabular development after closed reduction in DDH. Methods A total of 100 single side DDH children who were treated by “the treatment mode of closed reduction” from January 2002 to December 2005 were followed up, including 18 males and 82 females, with the average age of 19.4 months (ranging from 7 months to 36 months). Sixty-eight patients had left side dislocation, while 32 had right side dislocation. According to Zionts dislocation grades, 15 cases were degree I, 50 degree II, 26 degree III and 9 degree IV. Adductor tenotomies and skeletal traction were carried out in 74 cases, while direct closed reduction was performed in 26 cases. The four-level functional evaluation criterion was used to assess the cl inical therapeutic effect. Lesional and homeochronous normal hips were paired, and acetabular index (AI) and AI (D/W) of lesional and normal hips, before the reduction and in the 3rd, 6th, 9th and 12th month, respectively, after the reduction, were dynamically measured. Results The total choiceness rate of 100 children was 88.00%. Twelve months after the reduction, lesional AI decreased from (37.17 ± 2.17) o to (27.02 ± 3.54) o, while lesional AI(D/W) increased from 22.06% ± 1.65% to 29.80% ± 3.56%, and the differences among each time-point had statistical significance (P lt; 0.01). Both rates of lesional AI decrease and AI(D/W) increase were obviously faster than those of normal side physiological development (P lt; 0.01). In all durations after 12 months reduction, the rates of lesional AI were (3.22 ± 1.42) o and (3.41 ± 2.03) o in 1 - 3 months and 10 - 12 months , respectively, and the rates of AI(D/W) were 2.69% ± 1.83%and 2.33% ± 1.13%, respectively, and they were obviously faster than the other durations (P lt; 0.01). Both rates of lesional AI decrease and AI(D/W) increase were obviously faster than the homeochronous rate of normal side physiological development in each duration (P lt; 0.01). The rates of lesional AI were (13.71 ± 3.96) o and (11.48 ± 4.15) o in 7 - 12 age group and 13 - 18 age group, respectively, and the rates of AI(D/W) were 9.95% ± 3.81% and 8.28% ± 3.58%, respectively, and they wereobviously faster than the other age groups (P lt; 0.05). Both changes of lesional AI and AI(D/W) were obviously faster than the homeochronous changes of normal side in each age group(P lt; 0.01). Conclusion There are simple operating requirements and fine therapeutic effect of “the treatment mode of closed reduction” . Within 12-month after the closed reduction treatment, the rate of lesional acetabular development is obviously faster than that of normal side physiological development. The cresttime of lesional acetabular development is during 1 - 3 months and 10 - 12 months, and the best treatment time of closed reduction is the age before 18 months.
Objective To evaluate the curative effect of the total hip arthroplasty on the adult patient with osphyarthrosis due to hip infection sequela. Methods Fifteen patients (7 males, 8 females; age, 3656 years) with osphyarthrosis due to hip infection sequela underwent the total hip arthroplasty from May 2000 to March 2005. The patients were aged 8-15 years, averaged 11.3 years, when they began to suffer from osphyarthrosis. Their infection was interrupted for 23-44 years (average, 29.5 years) after they were given the total hip arthroplasty. Before operation, all the patients had anchylosis at the different degrees and the total activity range of the hip joint was 30-110°. Among the 15 patients, 4 had the limblength discrepancy of 2-6 cm (average, 3.8 cm) and 2 had a severe scar after the sinus was closed. All the patientsreceived the total hip arthroplasty performed by the senior surgeons. The small straight stem and the congenital dysplasia of the hip prosthesis were used in13 patients, the other 2 were given the ordinary prosthesis combined thestructural bone grafting. Two fixation patterns were respectively used in the cementless group (4 patients) and the cement group (11 patients). The patients inthe cementless group began to do the partiallyloading exercise at 3-4 weeks afteroperation; the patients in the cement group, 2 weeks after operation. The 2 patients with the structural bone allografting began to do the partiallyloading exercise 12 weeks after operation. Results The germiculture and the pathologicalexamination had a negative result in the tissues removed during operation. In the 4 patients with the shortened limbs, the limblength discrepancy was less than 1.3 cm. The followup for 49 months on average (range, 16.72 months) showedthat the Harris score increased from 46 points on average preoperatively to 90.5 points on average postoperatively. None of the patients had recurrent infection or injuries in the nerves and the blood vessels in the hip or aseptic loosening of the prosthesis. Conclusion The total hip arthroplasty in an adult patientwith osphyarthrosis due to hip infection can achieve a satisfactory curative effect in the early stage. The patient’s pain can be effectively relieved, and the problems of the poor motion degree of the hip joint and the limblength discrepancy can be effectively solved. Using the small acetabular prosthesis and the structural bone grafting can sufficiently reconstruct the anatomic acetabulum. If necessary, the small straight stem and the congenital dysplasia of the hip prosthesis can be used in the patient with severe deformity of the proximal femur.
