ObjectiveTo summarize the individualized diagnosis and treatment experience in a patient with primary pancreatic diffuse large B-cell lymphoma.MethodsBy muti-disciplinary term (MDT) model, a patient with primary pancreatic diffuse large B-cell lymphoma admitted in the People’s Hospital of Chishui in Dec. 2016 was discussed. The diagnosis, perioperative period management, and operation scheme were carried out by the MDT.ResultsThe patient’s general condition was good. After multidisciplinary discussion in the Department of Radiology, Oncology, Interventional, and Hepatobiliary and Pancreatic Surgery, the patient was considered to have surgical indications. After thorough communication with the patient and family, the patient was selected for surgical resection. The whole operation lasted for 5 hours, and the intraoperative blood loss was about 300 mL. The operation was successfully completed and no complications such as pancreatic fistula occurred after operation. Liquid drainage tube was drawn out at 10 days after opertion, and pancreatic tube stent and T tube were retained. The patient discharged on 13 days after surgery. Subsequently, the patient underwent adjuvant chemotherapy. At present, the patient has been followed up for 1 year, no signs of tumor recurrence and metastasis, and continued follow-up.ConclusionsPrimary pancreatic diffuse large B-cell lymphoma is rare and has a poor prognosis. The main treatment is mutli-mode treatment based on surgical resection combined with chemotherapy.
摘要:目的:探討改良De Vega環縮術與經典De Vega環縮術相比對于治療重度三尖瓣返流是否具有更好的成形效果。方法: 2007年12月至2009年3月對29例重度三尖瓣返流的患者行De Vega環縮術。其中16例行改良De Vega環縮術,13例行經典De Vega環縮術,隨訪比較兩組患者三尖瓣返流程度,右心室舒張期末內徑,EF值及心功能分級。以秩和檢驗分析研究兩組患者三尖瓣返流程度和心功能分級的差異,以t檢驗研究兩組患者右心室舒張末期內徑及EF值變化。結果:術前兩組患者一般指標無顯著差異。兩組患者隨訪時間無顯著差異。隨訪經典De Vega組重度返流1例,中度返流5例,輕度返流5例,微量及無返流2例;改良De Vega組無中、重度返流,輕度返流8例,微量及無返流8例。經分析顯示兩組患者三尖瓣返流程度結果差異有統計學意義(Plt;0.05)。經典De Vega組心功能分級I級5例,II級7例,III級1例;改良De Vega組I級7例,II級8例,III級1例,兩組患者心功能差異無統計學意義(Pgt;0.05)。兩組患者右室舒張期末內徑及EF值組內比較隨訪與術前差異均有統計學意義(Plt;0.05),隨訪時組間比較差異有統計學意義(Plt;0.05), 改良De Vega環縮術隨訪時右室舒張期末內徑縮小更顯著,射血分數改善更明顯。結論:改良De Vega環縮術治療重度三尖瓣返流效果優于經典De Vega環縮術。Abstract: Objective: To compare the efficacy of one kind of modified De Vega technique and traditional De Vega technique for the correction of severe tricuspid regurgitation. Methods: From December 2007 to March 2009, 29 patients were treated with tricuspid valve annuloplasty. These were 16 patients in modified De Vega annuloplasty group and the others (13 patients) in traditional De Vega annuloplasty group. The grade of tricuspid regurgitation、New York Heart Association (NYHA) functional class、ejection fraction (EF) and the right ventricular enddiastolic dimension of two groups were followed and reviewed. Results: There was no statistically difference between two groups about preoperative characteristics and followup time. There was 1 patient with severe TR, 5 patients with moderate TR, 5 patients with mild TR and 2 patients without TR in traditional De Vega annuloplasty group after the operations. In modified De Vega annuloplasty group, no patient was observed with severe or moderate TR, 8 patients with mild TR, and 8 patients without TR. At interval time, there was significant difference in the grade of tricuspid regurgitation between two groups (Plt;0. 05). Both tricuspid valve plasty techniques could reduce the right ventricular enddiastolic dimension and improve ejection fraction significantly (Plt; 0. 05), and there was significant difference in the right ventricular enddiastolic dimension and ejection fraction at interval time between two groups (Plt;0.05). Conclusions: The outcome of modified tricuspid De Vega technique is superior to that of traditional De Vega technique in correcting severe tricuspid regurgitation.
Objective To evaluate long-term effectiveness of recombinant human growth hormone (rhGH) for children with idiopathic short stature (ISS). Methods The randomized controlled trials (RCTs) about rhGH in treating ISS published from 1985 to 2010 were searched in PubMed, ScienceDirect, EBSCOHost, EMbase, The Cochrane Library, CBM, CNKI and VIP. According to the Cochrane Handbook, two reviewers independently screened literature, extracted data, assessed methodological quality, and conducted meta-analysis using RevMan 5.0 software. Results A total of 11 RCTs involving 607 ISS children were included. The results of meta-analysis showed that, compared with the blank/placebo control group after 1-year treatment, the rhGH group resulted in a significant increase in height standard deviation score (SDS) (MD=0.29, 95%CI 0.03 to 0.54, P=0.03), growth velocity (MD=2.68 cm/year, 95%CI 1.70 to 3.65, Plt;0.000 01), and adult SDS (MD=0.46, 95%CI 0.29 to 0.63, Plt;0.000 01). Conclusion rhGH can effectively promote the growth of ISS children. But due to the limitation of quality and small sample size of the included studies, its effectiveness still needs to be further proved by more high quality RCTs.
Objective To compare BODE index with GOLD staging for the severity evaluation in patients with chronic obstructive pulmonary disease ( COPD) . To investigate the relationship between BODE index and quality of life. Methods A total of 100 patients with stable COPD were enrolled. All participants were examined with lung function test and St George’s Respiratory Questionnaire ( SGRQ) for evaluation of quality of life. BODE index and it’s four components including body mass index( BMI) , airflow obstruction ( FEV1%pred) , dyspnea( MMRC) , and exercise capacity( 6MWD) were calculated. The participants were divided into four groups of severity using GOLD guidelines and BODE index quartiles. Results The associations between SGRQ total score and SGRQ subscales, and BODE index were significant( P lt;0. 01) .BODE index was a significant predictor of the quality of life, explaining 41. 3% of the total score of the SGRQ ( P lt;0. 01) . However, GOLD classification showed a correlation only with SGRQ activity score ( P lt;0. 05) but not with other SGRQ scores. There were significant differences in SGRQ total score and SGRQsubscales between different severity groups of BODE index( P lt;0. 01) . But there was no difference in SGRQ score between different severity groups of GOLD classification, except SGRQ activity score. Conclusion BODE scoring system is better correlated with the quality of life as assessed by the disease severity inpatients with COPD than the GOLD staging criteria.
Objective To investigate the safety and efficacy of completely thoracoscopic lobectomy and the indications of this procedure. Methods Between Sep. 2006 and Jun. 2008, 100 consecutive patients（46 men，54 women, median age60.1±12.5 years，range from 18 to 82 years) underwent completely thoracoscopic lobectomy. All candidates were either peripheral pulmonary nodules suspected of lung cancer (85 pts.) or benign lesions (15 pts.) localized within single lobe who needed to receive lobectomy. The lobectomy was completed through three tiny incisions in the intercostal space. Anatomic lobectomies were carried out in all cases and systemic lymph node dissection was performed in malignancies. This group consisted of lobectomies of right upper lobe (n=25), right middle lobe (n=14), right lower lobe (n=22), left upper lobe (n=18), and left lower lobe (n=21). Results All procedures were successfully completed except for 3 conversions to thoracotomy. Postoperative diagnosis were primary lung cancer (n=81), lymphoma (n=1), metastasis of clear cell carcinoma from kidney (n=1), and, benign lesions (n=17). Five patients had mild complications in which two had atelectasis, one needed temperately echanical ventilation, one had pneumonia and one had chylothorax. All were treated conservatively without reoperation. No operative mortality or serious complications occurred in this group. The operative duration was 186.4±52.9min (range from 60 to 300 minutes). The blood loss was 233.9±275.9ml（range from 50 to 750ml）, and only one case needed blood transfusion. Chest drainage time was 7.1±3.0 days. Postoperative hospital stay was 9.5±3.2 days. Followedup time was for 1 to 27 months, metastasis happened in two patients with primary lung cancer 15 and 3 months separately after operation. Conclusion The completely thoracoscopic lobectomy is a safe and feasible surgical procedure with minimal invasiveness. The advocated indications include selected peripheral typed early stage lung cancer and benign pulmonary lesions which need lobectomy.
Objective To discuss the diagnostic value of multidetector CT(MDCT) on encapsulated fat necrosis after operation of abdominal cancer, and to investigate the key differences of CT features between encapsulated fat necrosis and postoperative recurrence or metastasis. Methods CT data of 36 patients with encapsulated fat necrosis after operation of abdominal cancer, who received CT in our hospital between Feb. 2012 to May. 2014 during followed-up were retrospectively analyzed, for the purpose of summarizing the CT characteristics. In addition, the clinical presentation, level of carcinoembryonic antigen (CEA) and CA-125 before and after operation were also taken into account, to explore the difference between encapsulated fat necrosis with tumor recurrence and metastasis. Results Among the 36 patients who had suffered from encapsulated fat necrosis after operation of abdominal cancer, 3 patients (8.3%) had 2 lesions and the rest of 33 patients (91.7%) had solitary lesion(a total of 39 lesions). All lesions showed non homogeneous masses consistent with the surgery path and surrounded by fat density ring and soft tissue density capsule. The size of most lesions (94.8%, 37/39) decreased over time. All lesions were found slightly enhancement in portal phase. Five patients with postoperative tumor metastasis, 31 patients had no recurrence or metastasis. Among the 5 patients who had postoperative tumor metastasis at the same time, postoperative CEA was positive in 3 patients, and postoperative CA-125 was positive in 2 patient. Among the other 31 patients who had no recurrence or metastasis, the levels of postoperative CEA and CA-125 of 1 patient were unknown, and the postoperative CEA and CA-125 of 27 patients in the rest patients(90.0%, 27/30) were both negative. Most of them had no special clinical symptoms, only a few (1 patient)patient had mild abdominal pain without other associated symptoms. Conclusion CT is a valuable tool to reveal and diagnose encapsulated fat necrosis in postoperative abdominal cancer. Combined CT findings(such as location, shape, and density) with CEA, CA-125, and clinical presentation, that is easy to differ it from postoperative recurrence and metastasis.

ObjectiveTo compare the short-term clinical outcomes of laparoscopic pancreaticoduodenectomy (LPD) with open pancreatoduodenectomy (OPD).MethodsClinical data of 29 patients receiving LPD and 27 patients receiving OPD in the department of hepatobiliary surgery of the Second Affiliated Hospital of Chongqing Medical University from March 2016 to December 2018 were collected. Note that both LPD and OPD were performed by the same chief surgeon. Effectiveness and safety of LPD were compared with those of OPD.ResultsThere was no significant difference in age, sex, body mass index, total bilirubin level, direct bilirubin level, preoperative morbidities, focus size, TNM stage and ASA grade between the LPD group and the OPD group (P>0.05). The operative time of the LPD group was significantly longer than that of the OPD group ［(482±86 ) min vs. (349±73) min, P<0.01］. Patients in the LPD group had shorter postoperative anal exhaust time than that in the OPD group ［(3.3±0.8) d vs. (5.3±1.0) d , P<0.05］. There was no significant difference in the length of hospital stay after operation, blood loss in operation, transfusion, second operation, death and postoperative complications between the LPD group and the OPD group (P>0.05).ConclusionsThe preliminary results of this study suggest that compared with OPD, LPD can shorten the postoperative anal exhaust time but not increase the incidence of postoperative complications and blood loss in operation. Nevertheless, this conclusion is needed to be validated by clinical studies with large sample size.
ObjectiveTo improve recognization and effect of surgical treatment for solid pseudopapillary tumor of pancreas (SPTP) through multidisciplinary team (MDT) discussion.MethodsThe clinical data of 1 case of SPTP treated in The Second Affiliated Hospital of Chongqing Medical University were discussed by the MDT. The best operation scheme was selected and the patient was followed-up.ResultsThe preoperative CT scan showed that the occupation on the body and tail of pancreas and suggested it was the tumorous lesions. After the MDT discussion, the preoperative diagnosis was still not completely clear. However, the decision was made to resect occupation. After the operation, the pathological examination showed it was the SPTP. There was no recurrence or metastasis with the follow-up of 6 months.ConclusionsPreoperative diagnosis of SPTP is difficult, especially for atypical SPTP. Through MDT discussion, it can help to reduce misdiagnosis rate and formulate optimal surgical treatment strategy.
