ABSTRACT

Objective:To discussed the diagnostic value of magnetic resonance cholangiopancreatography (MRCP), and the use of laparoscopic surgery in management of patients with choledochal cyst with extrahepatic bile duct anomaly.Methods:Of 330 consecutive patients who underwent laparoscopic choledochectomy at Guangzhou Women and Children's Medical Center from January 2010 to September 2018, there were 23 patients with extrahepatic bile duct anomaly. The data of these patients were retrospectively analyzed. There were 4 males and 19 females, with an average age of 3.2 (range 0.3~9.0) years. According to whether the extrahepatic bile duct anomaly was diagnosed by preoperative MRCP, these patients were divided into the preoperative MRCP diagnosis group and the preoperative MRCP undiagnosed group. The impact of MRCP in diagnosing bile duct anomaly to prevent bile duct injury, on operation time, hospital stay and the types of extrahepatic bile duct anomaly on outcomes of laparoscopic treatment were analyzed.Results:All the 23 patients with choledochal cysts complicated by extrahepatic bile duct anomaly were confirmed at surgery. The incidence of extrahepatic bile duct anomaly was 6.97% (23/330). There were 47.8% of type II AHD (11/23); 36.8% of type III AHD (7/23); 4.3% of type IV AHD (1/23); 17.4% (4/23) of the type with communication with accessory bile duct (CABD). The preoperative MRCP diagnosis group consisted of 14 patients, while the preoperative MRCP non-diagnosis group consisted of 9 patients, including 2 patients without MRCP. The diagnostic rate of MRCP in preoperative diagnosis of extrahepatic bile duct anomaly was 66.7%(14/21). The preoperative MRCP undiagnosed group, when compared with the preoperatives MRCP undiagnosed group, had a significantly higher bile duct injury rate [preoperative MRCP diagnosis group 7.1%(1/14), preoperative MRCP non-diagnosis group 55.6%(5/9)], and a significantly longer operation time [preoperative MRCP diagnosis group(232.6±10.0) min, preoperative MRCP undiagnosed group (278.9±22.45)min], (all P<0.05). Laparoscopic surgery was completed in 22 of 23 patients. One patient was converted to open surgery. AHD reconstruction was needed in 11 patients with type II AHD and 1 patient with type IV AHD. Seven patients with type III AHD did not require any surgical intervention for the anomaly. The 4 patients with CABD underwent simple ligation. Postoperative chyloperitoneum developed in 1 patient, who successfully responded to conservative treatment. Postoperative recovery was uneventful in the remaining patients. At a median follow-up of 2 years (range 1 to 5 years), no further complications, including intrahepatic bile duct dilatation and hepatic atrophy were detected. Conclusions:MRCP was effective in preoperative diagnosis of choledochal cysts with extrahepatic bile duct anomaly. It helped to decrease intraoperation injuries to bile duct anomalies. MRCP was also useful in classifying patients with extrahepatic bile duct anomaly to better preoperatively planning of surgical treatment strategies. Laparoscopic surgery could be completed in the majority of these patients with good postoperative results.

ABSTRACT

Objective:To study the clinical outcomes of children with extrahepatic portal venous obstruction who underwent balloon venoplasties for anastomotic stenosis after Meso-Rex bypass.Methods:The data of 60 patients who underwent Meso-Rex bypass at Guangzhou Women and Children’s Medical Center between October 2014 and November 2018 were retrospectively analyzed. Four patients were shown by transhepatic portal venography to have graft stenosis in the left portal vein anastomosis. There were 2 males and 2 famales, the age of patients were 11 years, 5 years, 5 years and 8 years. Four patients underwent balloon dilation. The pressure, anastomotic diameter and blood flow velocity of the anterior portal vein were compared before and after balloon dilation. The patients were followed-up on the postoperative status.Results:Three of 4 patients who had anastomotic stenosis were successfully treated by balloon venoplasties. On postoperative follow-up for 6 months, the bridging vessels remained unobtrusive and there was no gastrointestinal bleeding. The pressures of the anterior hepatic portal vein before balloon dilation were 19, 15 and 25 mmHg (1 mmHg=0.133 kPa). They were 8, 11 and 20 mmHg after balloon dilation. The preoperative anastomotic diameters were 2.6, 3.0 and 3.0 cm. They were 6.0, 4.5 and 5.5 cm, respectively 6 months after surgery. The preoperative anastomotic blood flow velocities were 138, 107 and 94 cm/s. They were 96, 91 and 90 cm/s, respectively 6 months after surgery. The preoperative three-dimensional CT reconstruction of spleen volumes were 793.24, 192.25, and 318.05 cm 3, respectively. They were 681.84, 190.30, and 310.65 cm 3, respectively 6 months after surgery. In the remaining patient, balloon dilation failed because of the small diameter of the anastomotic stenosis segment. Conclusion:Balloon venoplasties is an optional procedure for patients with anastomotic stenosis after Meso-Rex bypass.

ABSTRACT

Objective@#To study the diagnosis and management of choledochal cyst in children with accessory hepatic ducts (AHD).@*Methods@#From November 2013 to June 2018, 14 patients with choledochal cyst with AHD were treated in Guangzhou Women and Children's Medical Center. The patients included 2 males and 12 females, and age ranged from 4 months to 3 years (median 2 years). All patients underwent MRCP before operation, and 2 underwent operative cholangiography through the AHD.@*Results@#Seven patients with choledochal cyst and AHD were demonstrated by preoperative MRCP and intraoperative exploration. One patient was suspected by preoperative MRCP to have AHD which was confirmed by surgical exploration. Preoperative MRCP failed to diagnose, but operative exploration revealed AHD in 6 patients. Anastomosis of the AHD to jejunum was performed laparoscopically in 8 patients and by open surgery in 1 patient. Six patients had the common hepatic duct and the AHD joined together to create a common channel which was then implanted as a single duct into a Roux loop, Three patients had the common hepatic duct and the AHD anastomosed separately to a Roux loop. All the patients recovered well after operation and they were discharged home without any complication. A follow-up which ranged from 0.5 to 5 years showed no jaundice, liver atrophy or liver abscess.@*Conclusions@#MRCP was important in the preoperative diagnosis of choledochal cyst with accessory hepatic duct in children. MRCP was difficult in diagnosing type II accessory hepatic ducts. In suspected or undiagnosed cases of AHD, surgical exploration helped to improve the diagnostic accuracy, avoided injury and guided correct surgical decisions. Reconstruction of AHD required joining the AHD to the common hepatic duct, or as a separate duct to jejunal anastomosis to a Roux-y-loop.

ABSTRACT

Aim To investigate the effect of broneol on acute lung injury(ALI) induced by lipopolysaccharide (LPS). Methods Male C57 mice were randomly di-vided into saline group, model group, broneol group and dexamethasone group, then the ALI mouse model was induced by instilling intratracheally with LPS. The levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),interleukin-6(IL-6) and keratinocyte-de-rived cytokine (KC) were measured at 6h, 12h and 24h after instillation of LPS, and the pathological changes of lung were observed. Mice alveolar macro-phages (MHS) and epithelial cells (MLE-12) were stimulated by LPS. After the stimulation of 1h, 3h, 6h,9h, 12h, 24h, the levels of TNF-α and IL-6 in MHS cells and the contents of KC and macrophage in-flammatory protein-2 (MIP-2) in MLE-12 cells were measured. Results Broneol could inhibit the secre-tion of TNF-α,KC and IL-1β;the early effect of bro-neol on IL-6 was not obvious,but the later effect after the treatment of 24 hours was obvious. After LPS instil-lation 6h and 12h,Broneol could significantly improve lung tissue pathological changes. Broneol had no effect on TNF-α secretion of MHS cells, but it obviously af-fected IL-6 secretion in the later stage. In addition, broneol significantly inhibited KC and MIP2 secretion in MLE-12 cells at the later stage of LPS stimulation. Conclusions Broneol can protect LPS-induced acute lung injury. The mechanism may be related to the inhi-bition of the release of inflammatory factors,the activa-tion of inflammatory cells and the aggregation of neutro-phils.

ABSTRACT

Objective To observe the clinical efficacy of acupoint thread embedding plus thunder-fire moxibustion in treating hyperlipidemia due to spleen-kidney yang deficiency. Method Sixty patients with hyperlipidemia due to spleen-kidney yang deficiency were randomized into a treatment group and a control group, 30 cases each. The treatment group was intervened by acupoint thread embedding plus thunder-fire moxibustion, while the control group was intervened by oral administration of Atorvastatin calcium tablets. After 8-week treatment, changes in the serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and traditional Chinese medicine (TCM) syndrome score were observed in the two groups, and the clinical efficacies were compared. Result The blood lipids indexes (TC, TG, HDL-C and LDL-C) and TCM syndrome score were significantly changed after the treatment in both groups (P<0.05). After the treatment, the blood lipids indexes and TCM syndrome score of the treatment group were insignificantly different from those of the control group (P>0.05). The total effective rate was 90.0% in improving the blood lipids in the treatment group, versus 93.3% in the control group, and the between-group difference was statistically insignificant (P>0.05). The total effective rate was 83.3% in improving the TCM syndrome score in the treatment group versus 63.3% in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Acupoint thread embedding plus thunder-fire moxibustion is an effective method in treating hyperlipidemia due to spleen-kidney yang deficiency.

ABSTRACT

<p><b>BACKGROUND</b>Circulating endometrial cells (CECs) have been reported to be present in the peripheral blood of women with endometriosis (EM), providing clear and specific evidence of the presence of ectopic lesions. In this study, we established a method with a high detection rate of CECs, assessed the diagnostic value of CECs for EM and compared with serum CA125, and proposed a hypothesis for the pathogenesis of EM from the new perspective of CECs.</p><p><b>METHODS</b>The participants were enrolled prospectively from October 2015 to July 2016. The peripheral blood samples were collected from 59 participants, and the blood cells were isolated for immunofluorescence staining via microfluidic chips. The cells that were positive for vimentin/cytokeratin and estrogen/progesterone receptor and negative for CD45 were identified as CECs. The serum CA125 level was tested with electrochemiluminescence immunoassay.</p><p><b>RESULTS</b>The detection rate of CECs reached 89.5% (17/19) in the EM group, which was significantly higher than that of the control group (15.0% [6/40], P < 0.001) and was independent of menstrual cycle phases. Furthermore, a positive CEC assay detected 4/5 cases of Stage I-II EM. In contrast, a positive CA125 test had limited value in detecting EM (13/19, 68.4%) and detected only one case of Stage I-II EM.</p><p><b>CONCLUSION</b>CECs are promising biomarkers for EM with great potential for a noninvasive diagnostic assay.</p>

Objective To assess the mid-term result of laparoscopy in resection of choledoehal cyst,hepaticojejunostomy and discuss the technical improvement.Methods Retrospectively analyzed the data of 31 patients who had undergone laparoscopic choledochal cyst excision from November 2010 to November 2012.Under laparoscopic guidance,intraoperative cholangiogram was performed,Rorx-Y jejunojejunostomy was performed extracorporeally through umbilical incision,then the dilated bile duct were completely excised and a hepaticojejunostomy was carried out intracorporeally.Results Twenty-nine patients successfully underwent laparoscopic choledochal cyst resection,while 2 patients were converted to open surgery because of severe adhesion.The mean operation time was 260 minutes (range from 200 to 460 minutes).A follow-up of 3 to 27 months were achieved in all patients.Three patients developed early complications:one bile leakage,one incision port hemorrhage and one intestinal torsion.The laboratory tests were normal and no dilation of the bile duct was detected in all patients.Conclusions Laparoscopic total cyst excision with Roux-Y hepaticojejunostomy was effective and safe procedure with satisfied results.

ABSTRACT

Objective To evaluate the lymphoscintigraphic imaging characteristics for the patients with lower limb lymphedema and to establish a novel grading system for the injury to lower limb lymphatic system. Methods One hundred and sixty six consecutive patients (332 lower limbs) with lower limb lymphedema after surgical and(or) radiotherapy treatment for gynecological cancer were recruited into this retrospective study. The lymphoscintigraphy studies were performed after subcutaneous injection of 111~185 MBq (0. 1~0. 15 ml) of 99Tcm-DX into the webbed space between the first and second toes of both feet. Based on the integrity of lymphatic vessel and the extension of dermal diffusion on lymphoscintigram,the lymphatic injury to the lower limb was graded as 0, 1,2 and 3 respectively. The lymphedema of the limb was staged as 0, Ⅰ , Ⅱ a, Ⅱ b, Ⅲ by the standard of Consensus Document of the International Society of Lymphology (ISL). Chi square test was carried out to validate the established grading system for the assessment of the injury to the lower limb lymphatic system. Results The lymphoscintigraphic imaging characteristics included lymphatic blockage, dermal backflow, no visualization of lymphatic or lymph node, lymphocele and lymph fistula in the lower limb, pelvis and abdomen. There were 65 (19.6%), 71 (21.4%),131 (39.5%), 62 (18.7%) and 3 (0.9%) limbs staged as 0, Ⅰ , Ⅱa, Ⅱb, and Ⅲ for lymphedema while 36(10.8%), 79(23.8%), 116(34.9%) and 101 (30.4%) limbs graded as 0, 1, 2, and 3 for lymphatic injury. There was a statistically significant correlation between the grading methods (χ2 =313.483, P <0.001). The patients who underwent radiotherapy had a higher incidence rate of grade 2 and 3 (70.5%, 158/224) than those who underwent surgery (53.6%, 59/108) (χ2 = 9.662, P = 0.022).The patients with erysipelas had a higher incidence rate of grade 3(73.1%, 38/52) than those without erysipelas (43.9%, 50/114) (χ2= 12.238, P<0.001). The incidence rate of grade 3 increased with the duration of lymphedema after treatment: 36.6% (34/93) for less than 1.5 years, 72.3% (34/47) for between 1.5 to 5 years, and 76.9% (20/26) for more than 5 years (χ2 = 23.123, P<0.001). The grade of lymphatic injury showed no significant difference among 3 types of gynecological cancers (χ2 = 4.000, P =0.676), or between the patients with and without chemotherapy (χ2 =0.411, P=0.938). Conclusions Lymphoscintigraphy is a reliable modality to diagnose lower limb lymphedema after treatment for gynecological cancer. The injury grading system could provide objective assessment of the lymphatic damage.
