ObjectiveTo investigate the therapeutic effect of modified tricuspid valvuloplasty using anterior leaflet in patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia. MethodsNinety-five patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia underwent surgical treatment in our hospital from June 2002 to March 2014. There were 39 males and 56 females with an average age of 3.2±6.6 years (range 3 months to 46 years). Preoperative echocardiography prompted all patients had varying degrees of tricuspid valve dysplasia and tricuspid regurgitation (mild in 14 cases, moderate in 49 cases, and severe in 32 cases). According to the different development of anterior and septal leaflet, we used different techniques to repair the tricuspid problems. If the residual septal leaflet was larger than one third of the normal septal leaflet, we continuously stitched the half of the septal side of anterior leaflet to the two third of the left side of residual septal leaflet. If the residual septal leaflet was less than one third of the normal septal leaflet, we reserved part of pericardial patch at right side of septal crest at repairing the atrial septal defect, and continuously stitched the left two third of the patch edge to the half of septal side of anterior leaflet. All patients received transesophageal echocardiography (TEE) to evaluate the intraoperative effect of valvuloplasty. The patients were followed up with echocardiography after 3 to 6 months to evaluate the condition of tricuspid. ResultsThere was no perioperative death or Ⅲ degree atrioventricular block. Intraoperative TEE showed that the effect of tricuspid valvuloplasty was good with 3 cases of mild regurgitation and 2 cases of moderate regurgitation. Other 90 cases had no significant regurgitation. The aortic cross-clamping time was 35.2±11.2 min and cardiopulmonary bypass time was 64.9±16.6 min. In the followed-up between 3 to 6 months, tricuspid regurgitation situation improved significantly than that in preoperative period with mild regurgitation or no reflux in 89 cases and moderate regurgitation in 6 cases. There was no severe regurgitation occurred. ConclusionThe therapeutic effect is satisfactory by using anterior leaflet to repair the regurgitation of tricuspid in patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia.
ObjectiveTo explore the effect of partial splenic embolization on splenectomy plus devascularization of esophageal and gastric vein. MethodsTwenty three cirrhosis patients with portal hypertension combined the hypersplenism (partial splenic embolization group), who received partial splenic embolization in our hospital from June 2010 to June 2015, as well as 30 cirrhosis patients with portal hypertension combined the hypersplenism without undergoing partial splenic embolization in the same period (non-partial splenic embolization group), were collected retrospectively. All patients underwent splenectomy plus devascularization of esophageal and gastric vein. Comparison of operation time, intraoperative blood loss, intraoperative blood transfusion volume, postoperative total flow of abdominal drainage tube, postoperative gastrointestinal function recovery time, hospital stay, and the incidence of complication was performed. ResultsThe operation time[(3.56±0.70) h vs. (1.78±0.28) h], intraoperative blood loss (900 mL vs. 250 mL), intraoperative blood transfusion volume (800 mL vs. 200 mL), postoperative total flow of abdominal drainage tube (450 mL vs. 150 mL), postoperative gastrointestinal function recovery time[(43.38±18.68) h vs. (27.60±12.39) h], hospital stay (12 d vs. 7 d), and incidence of incision infection[34.8% (8/23) vs. 10.0% (3/30)] of partial splenic embolization group were all higher or longer than those corresponding indexes of non-partial splenic embolization group (P < 0.05). All patients of 2 groups were followed up by telephone visit for 6-58 months, and the median was 28-month. There was no recurrence of gastrointestinal hemorrhage during the follow-up period. ConclusionsSplenectomy is more difficult, and maybe has more intraoperative blood loss and complications for cirrhosis patients with portal hypertension combined the hypersplenism, who received partial splenic embolization ever. For these patents, the recovery time is longer. We should make choice of partial splenic embolization or splenectomy directly according to the patients' situation, to implement individualized treatment, so we can make the biggest benefit for patients.
Objective To evaluate the effect of composite (bFGF/PDPB) of basic fibroblast growth factor(bFGF) and partially deproteinized bone (PDPB) on the repair of femoral head defect. Methods Forty-eight femoral heads with defect derived from 24 New Zealand rabbits were divided into 3 groups at random, which were implanted with bFGF/PDPB(group A), PDPB(group B) and nothing(group C) respectively.The rabbits were sacrificed at 2,4,and8 weeks after operation, and then the femoral heads were obtained. The specimens injected with Chinese ink were created. Then X-ray examination, histopathological and morphological examination of blood vessel, and image analysis were made. Results The bone defects healed completely 8 weeks after operation in group A. The implants in the repaired tissue were not substituted completely in group B. The bone defects did not heal completely in group C. Two weeks after operation, affluent newly formed vessels were seen in repaired areas in groupA. No significant difference between group A and group B was observed 8 weeks after operation. In group C, newly formed vessels were scarce 2, 4, and 8 weeks after operation. There were 3 sides rated excellent, 2 good and 1 fair in group A; 1 excellent, 2 good, 2 fair and 1 poor in group B; and 1 fair and 5 poor in group C according to the X-ray evaluation 8 weeks after operation. Eight weeks after operation, the volume fraction of bone trabecula in repaired tissue was higher in group A than that in group B (Plt;0.05), and the fraction in group C was thelowest among the 3 groups (Plt;0.05). Conclusion The composite ofbFGF and PDPB can effectively promote the repair of femoral head defect of rabbit.
Objective To summarize experiences of surgical treatment and long-term results of myasthenia gravis (MG). Methods Two hundred thirty-six patients underwent thymectomy for MG in our department from Jan.1978 to Dec. 2002. The perioperative management, relative factors of postoperative crisis and long-term results were analysed. Results In 236 patients postoperative crisis took place in 44 cases accounted for 18.6%. The occurrence of postoperative crisis was related to preoperative management, modified Osserman clinical classification and combination with thymoma. Three cases died in the postoperative periods. Among them, one died of acute respiratory distress syndrome induced by aspiration and the other died of crisis. The effective rate in 1, 3, 5 years was 84.6%, 91.0% and 89.0% respectively. Conclusions Thymectomy for MG is safe and effective. Delayed extubation could decrease the needs of tracheotomy in patients with high risk factors for postoperative crisis. The partial sternotomy approach is less traumatic but the long-term effects of surgery are identical to those reported by the most authors.
ObjectiveTo objectively evaluate the effectiveness of the ventricular fold pull-down combined with strip myofascial flap to repair laryngeal defect after early glottic carcinoma operation with glottic morphological parameters and voice parameters. MethodsBetween January 2008 and December 2012, 47 patients with early glottic carcinoma and anterior commissure involvement underwent partial laryngectomy. All patients were male, aged from 60 to 75 years (mean, 68.5 years). The disease duration was 4-11 months (mean, 7.2 months). According to American Joint Committee on Cancer (AJCC) TNM criteria, 28 cases were classified as T1aN0M0, 14 cases as T1bN0M0, and 5 cases as T2N0M0. Laryngeal defect after resection of tumor was repaired by ventricular fold pull-down combined with strip myofascial flap. At 1 day before operation and at 1 year after operation, multilayer spiral CT was used to scan larynx, to measure and compare the anteroposterior diameter of vocal area, the distance between both sides of the vocal process, and the thickness of soft tissue of vocal area, and the effect of combined soft tissue flap was objectively assessed in laryngeal morphology reconstruction. The actual voice parameters[including F0, Jitter, Shimmer, normalized noise energy (NNE), and maximum phonatory time (MPT)] were tested and compared, and the effect of the combined soft tissue flap on postoperative laryngeal pronunciation was evaluated. ResultsPostoperative pathological examination revealed well-differentiated squamous cell carcinoma in 38 cases, and moderately-differentiated squamous cell carcinoma in 9 cases; no tumor was found in the resection margin. Healing of neck incision was obtained in all patients at 7-9 days after operation. Forty-four cases were decannulated at 9-11 days after operation and the remaining 3 cases were decannulated at 3 weeks after operation. Oral feeding usually started in all cases at 3-4 days after operation. All patients were followed up 1 year. At 1 year after operation, the anteroposterior diameter of vocal area was significantly reduced when compared with preoperative one (t=15.161, P=0.000); the distance between both sides of the vocal process and the thickness of soft tissue of vocal area had no significant changes (P > 0.05). Compared with preoperative ones, there were significant differences in Shimmer, NNE, and MPT (P < 0.05), but no significant difference was found in F0 and Jitter (P > 0.05) at 1 year after operation. ConclusionVentricular fold pull-down combined with strip myofascial flap can repair laryngeal defect effectively after partial laryngectomy and maintain the effective airway after operation. It not only has no effect on postoperative laryngeal morphology, but also can be used as new laryngeal voice vibration body.
ObjectiveTo understand the effect of nitric oxide (NO) on the formation of hyperdynamic circulatory syndrome (HCS) and the influence of level of NO on HCS. MethodsAfter establishment of stable HCS in partial portal vein ligated rats,the quantity of NO in blood of portal vein and the activity of nitric oxide synthase (NOS) in liver were determined by pre and post injection of inhabitor of NOS (NGmethylLarginine) and hemodynamics was supervised simultaneously.ResultsThe quantity of NO was paralleled with the activity of NOS and was elevated markedly by 24 hours after operation and reached the top by 48 hours after surgery. These sequential changes were coincided with the dilation of general vascularture. There was a close relation between this changes and the formation of HCS.The quantity of NO and the activity of NOS were decreased significantly to the level of the control group after injection of NGmethylLarginine (LNMMA). LNMMA inhabited the activity of NOS and blocked the production of NO. HCS ameliorated obviously. ConclusionNO plays an important role in initiating the dilation of general vascularture and plays a critical role in the formation of HCS. HCS will be ameliorated obviously or be blocked completely by eliminating the effect of NO and the portal pressure will decreased significantly or recover to normal range.
ObjectiveTo systematically evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with partial splenic embolization (PSE) for hepatocellular carcinoma (HCC) with hypersplenism. MethodWe searched The Cochrane Library (Issue 11, 2015), PubMed, EMbase, CBM, VIP, CNKI and WanFang Data databases from inception to November 1st 2015, to collect randomized controlled trials (RCTs) about TACE combined with PSE in treating HCC with hypersplenism. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 11 RCTs involving 708 patients were included. The results of meta-analysis showed that: Compared with TACE alone, TACE combined with PSE could significantly improve postoperative CD4 count (MD=6.99, 95%CI 4.60 to 9.38, P<0.00001), CD4/CD8 ratio (MD=0.64, 95% 0.45 to 0.84, P<0.00001), and the rate of half year survival (RR=1.16, 95%CI 1.02 to 1.32, P=0.02), decrease the incidences of spontaneous peritonitis (RR=0.20, 95%CI 0.05 to 0.48, P=0.03) and varices bleeding (RR=0.17, 95%CI 0.04 to 0.68, P=0.01). The two groups had similar incidence of post-embolization syndrome (RR=1.17, 95%CI 0.79 to 1.75, P=0.44). ConclusionTACE combined with PSE is more safe and effective than TACE alone in unresectable HCC with hypersplenism. Due to limited quantity and quality of the included studies, the above conclusion should be further verified by conducting more high quality, large scale RCTs.
ObjectiveTo investigate the effect of external dissection and internal ligation, plus partial internal sphincterotomy in the treatment of mixed hemorrhoids. MethodsDuring January 2010 to January 2012, 364 patients with mixed hemorrhoids selected for surgery were divided into two groups based on whether the patients should accept the treatment of partial internal sphincterotomy. We observed the curative effect of the two groups, including anal pain, bleeding, edema, average healing days and the anorectal stenosis after operation. ResultsThere were statistical differences between the two groups in terms of anal pain, complication rate and hospital stay (P<0.01). The curative effect of the group treated with partial internal sphincterotomy was better than that of the other group. ConclustionExternal dissection and internal ligation, plus partial internal sphincterotomy is a better choice in the treatment of mixed hemorrhoids, which can relieve postoperative symptoms, reduce complications and shorten treatment course.
Objective To explore the clinical value of pleura biopsy and partial pleura cryobiopsy via electronic bronchoscope in diagnosis of unknown exudative pleural effusion. Methods Diagnostic results of 563 patients with unknown exudative pleural effusion were analyzed retrospectively. Bronchoscope and routine pleura biopsy were performed in 187 patients. Bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy were performed in 376 patients. Pathological positive rates of the two groups were compared. Results In the 187 patients examined by bronchoscope and routine pleura biopsy from 2006 to 2008, 161 patients obtained pathological positive results ( 86.1% ) . In the 376 patients examined by bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy from 2009 to 2012, 354 patients acquired pathological diagnosis ( 94.1% ) . There was significant difference between the two groups ( P lt; 0.05) . The main complications were bleeding and local chest pain, and they can be controlled easily. Conclusions Electronic bronchoscope and pleura biopsy can obtain high detection rate of nearly 90% in diagnosis of unknown exudative pleural effusion especially when combined with cryobiopsy of partial pleura. Electronic bronchoscope combined with pleura biopsy or cryobiopsy is an alternative in clinical settings when thoracoscope is unavailable.
Thirty-six partial hepatectomies for patients with symptomatic intrahepatic stones is reported.Partial liver resection should be done when the liver containing strictrue(s),dilated ducts and stones.Meanwhile,additional procedures should be performed togather with partial hepatectomy,i,e,common duct exploration and drainage,cholangiotomy and cholangioplanty,and cholangeoenterostomy,according to the location of stones and ductal strictures.Postoperative long-term follow-up in this series showed that the results of 86.2% of patients were satiffactory.Partial hepatectomy can be considered as a better treatment of choice for the stones confined to one segment or lobe of liver or combined with multiple strictures of ducts.
