Objective To investigate somatic growth of children undergoing stageⅡ Fontan procedure. Methods Clinical data of 152 children who underwent stageⅡ Fontan procedure in Shanghai Children’s Medical Center, Shanghai Jiaotong University School of Medicine between January 2012 and December 2015 were reviewed. There were 84 males and 68 females at age of 4-16 years. The weight and height of those children in each operative stage were assessed, and WHO Z-score was obtained to describe the pattern of growth of the children. Results Mean weight for age Z-score (WAZ) and height for age Z-score (HAZ) were –0.73 and 0.06 at birth, –1.27±1.37 and –1.27±1.72 before Glenn procedure, –0.47±1.08 and –0.69±1.17 before Fontan procedure, –0.42±1.18 and –0.39±1.48 at follow-up, respectively. A significant decline (P<0.05) in WAZ and HAZ was found before Glenn procedure. After the Glenn procedure, there was significant catch-up growth (P<0.05). The WAZ was stabilized after Fontan procedure, while the HAZ was reversed (P<0.05) continually. Conclusion The somatic growth is impaired in children with stageⅡ Fontan procedure. There is a trough of growth before Glenn procedure. Although catch-up growth occurs after Glenn procedure, low body weight and growth retardation remain at follow-up. Effective interventions such as more intensive nutritional strategies before Glenn procedure should be targeted at those children in the future, so as to improve their growth.
ObjectiveTo evaluate the possibility of monitoring regional tissue oxygen saturation by near-infrared spectroscopy (NIRS) for early predicting adverse events in patients with pulmonary atresia.MethodsTwenty-six patients aged under 3 months who were diagnosed with pulmonary atresia and admitted to cardiovascular intensive care unit in our hospital between January 2016 and May 2017, accepted regional tissue oxygenation (cerebral and splanchnic) by near-infrared spectroscopy. There were 19 males and 7 females at age of 2–89 days. A total of 625 times of heart rate, blood pressure, pulse saturation, regional tissue oxygenation, and 98 serum lactate were retrospectively analyzed. The relationship of the tissue oxygen saturation and clinical adverse events was explored.ResultsThe adverse event by routine monitoring was 69 (11.04%) person-time: isolated hypoxia in 27, hypoxia combined increased lactate in 16, hypotension in 6, hypotension combined increased lactate in 17, isolated increased lactate in 3. A reduction of 12.80% in cranial oxygen predicted the high probability of adverse events, with a sensitivity of 85.30% and a specificity of 87.00%. A reduction of 20.60% in splanchnic oxygen predicted the high probability of adverse event, with a sensitivity of 73.50% and a specificity of 91.2%. On average, the splanchnic oxygenation had fell 3 minutes before a reduction of blood pressure, or 45 minutes before an increase in lactate.ConclusionFor preoperative patients with pulmonary atresia, a fall of 12.80% in cranial oxygen saturations, or of 20.60% in splanchnic oxygen saturation, should attract clinician’s awareness.
Objective To explore the effect of pulmonary arterial hypertension on the children with functional single ventricle in the early period after Fontan operation. Methods Forty-three children with pulmonary arterial hypertension after Fontan operation were enrolled in our department between January 2015 and December 2016. There were 24 males and 19 females at a median age of 4.3 years ranging from 2.5 to 4.8 years. The pulmonary arterial pressure was evaluated by cardiac catheterization. There were 23 children diagnosed without pulmonary hypertension (a non-PAH group) including 16 males and 7 females, while 20 patients were diagnosed with pulmonary hypertension (a PAH group) including 8 males and 12 females. Postoperative parameters related to outcomes were compared between the two groups. Results There was no death in the non-PAH group, but the mortality of children in the PAH group was 20.0% (4/20, χ2=5.34, P=0.02). The central venous pressure (t=–2.50, P=0.02), N-terminal prohormone of brain natriuretic peptide (NT-proBNP, Z=–3.50, P<0.01), peritoneal dialysis rate (χ2=5.40, P=0.02), incidence of arrhythmia (χ2=4.40, P=0.03) in the PAH group were significantly higher than those of the non-PAH group. The early postoperative utilization rate of pulmonary vascular targeting agents in the PAH group was significantly higher than that in the non-PAH group (χ2=6.30, P=0.04). Conclusion Pulmonary arterial hypertension is one of the most important factors which influence the early postoperative prognosis of children with functional single ventricle after Fontan operation.
ObjectiveTo assess the predictive abilities of postoperative regional oxygen saturation (rSO2) measured by near-infrared spectroscopy (NIRS) and lactate level for early postoperative outcome in children undergoing congenital heart disease surgery.MethodsA total of 73 children (43 males, 30 females, mean age of 91±18 days) undergoing cardiovascular surgery were enrolled from December 2016 to September 2017. The 73 children were divided into an early poor outcome group and a without poor outcome group. Binary logistic regression method was used to determine the independent factors of predicting early poor outcome. Receiver operating characteristic curve was used to identify the optimal cutoff values.ResultsThe early poor outcome rate was 47%. By regression analyses, nadir splanchnic rSO2 values, peak lactate level were 2 independent factors of predicting poor outcome. For nadir splanchnic rSO2 alone, the area under the ROC curve for poor outcome were 0.897. For peak lactate alone, the area under the ROC curve for poor outcome was 0.867. After combination of nadir splanchnic rSO2 and peak lactate, the area under the ROC curve for poor outcome increased to 0.944 (P<0.05).ConclusionCombining the parameter of nadir splanchnic rSO2 and peak lactate during the first postoperatively 24 hours yielded to a more accurate predictive ability for early outcome in children undergoing congenital cardiac surgery.
Objective To study the effectiveness of one-stage repairing pharyngeal defect with the tongue flaps after resection of advanced stage hypopharyngeal neoplasm and laryngeal neoplasm. Methods Between June 2006 and March 2011, 20 patients with hypopharyngeal neoplasm (8 cases) and laryngeal neoplasm (12 cases) with advanced stage were treated. There were 19 males and 1 female, aged 47-78 years (mean, 62.8 years). All neoplasms were squamous cell carcinomas. The disease duration was 1-8.5 months (mean, 3.9 months). According to the standards of International Union Against Cancer (UICC, 1987), 12 cases were in stage III and 8 cases were in stage IV. The size of pharyngeal defect was 5 cm × 2 cm to 4 cm × 4 cm after resection of tumor. Defects were repaired by the whole base of the tongue flaps in 16 cases and by the horizontal base of the tongue flaps in 4 cases. The size of the flaps ranged from 5 cm × 2 cm to 4 cm × 4 cm. Postoperative radiotherapy and chemotherapy were regularly performed. Results The 20 tongue flaps were alive. Healing of incision by first intention was achieved in 18 cases and delayed healing in 2 cases because of subcutaneous fluid. The patients were followed up 12-63 months (mean, 36.7 months). The patients had normal feeding ability and tongue function. Of 20 cases, 12 died and 1 of local recurrence was alive with tumor. The 3-year survival rate was 69.2% (9/13). Conclusion One-stage repair of pharyngeal defect with the tongue flaps after resection of hypopharyngeal neoplasm and laryngeal neoplasm can obtain good effectiveness because the tongue flap is easy-to-obtain and easy-to-survive, and has abundant blood supply.
Objective To discuss and evalue the effects and the advantages of pectoral is major myocutaneous flap in repair of defect caused by resection of tonsillar cancer. Methods The data were retrospectively summarized from 10 patients with recurrent tonsillar cancer after radical radiotherapy from January 1998 to December 2005, including 7 cases of squamouscell carcinoma, 2 cases of undifferentiated carcinoma, and 1 case of adenoid cystic carcinoma. There were 8 males and 2 females, aged 43-68 years with an average of 58 years. All cases were classified as stages III and IV before radiotherapy according to staging standard of oropharyngeal cancer (International Union Against Cancer, 1997). The time of relapse was 6-32 months after radiotherapy. Recurrent tonsil cancer invased tongue base, soft palate, posterior wall of pharyngeal, parapharyngeal space, and palate. Tumor size was from 4 cm × 2 cm to 8 cm × 5 cm. Seven cases were accompanied by lymph node metastasis. After carcinoma were completely resected and defects were reconstructed by pectoral is major myocutaneous flap of 7 cm × 5 cm- 12 cm × 9 cm. The donor sites were sutured directly. Results After operation, pectoral is major myocutaneous flap completely survived in 9 cases. Partial necrosis of pectoral is major myocutaneous flap was found in 1 case; after treatment, the necrotic flap remained small pharyngeal defect. Incision at donor site healed by first intention in 10 cases. All patients showed satisfactory functions of respiratory, voice, and swallowing with no compl ication. Ten patients were followed up 2 years to 5 years and 8 months. The 3-year survival rate was 66.7% (6/9), and the 5-year survival rate was 20.0% (1/5). Conclusion Pectoral is major muscle flap has a high survival rate, which is safe, rel iable, easy-to-operate, and can repair larger defect. Pectoral is major myocutaneous flap is an ideal material in repair of defect caused by resection of recurrent tonsillar carcinoma after radiotherapy.
Objective This study was conducted to evaluate and analyze the clinical effect between subtotal stomach-preserving pancreaticoduodenectomy (SSPPD) and pylorus-preserving pancreaticoduodenectomy (PPPD), especially compare the incidences of delayed gastric emptying (DGE) between them. Methods The documents about SSPPD and PPPD were searched in Cochrane Library, PubMed database, Embase database, Web of Science, Chinese biomedicine database, CNKI database, VIP database, and WanFang database. The quality of included studies was assessed according to the Cochrane systematic review methods, and statistical analysis of data was performed by using RevMan 5.3 software. Firstly, comparison of incidence of DGE and other effective indexes between SSPPD group and PPPD group was performed by enrolling all included studies, whether met the DGE standards of International Study Group of Pancreatic Surgery (ISGPS) or not, and then comparison of incidence of DGE and clinical DGE was performed by enrolling included studies that met the DGE standards of ISGPS. Results Ten studies were included, with a total of 804 patients, in which, 433 cases underwent SSPPD and 371 cases underwent PPPD. The results of meta-analysis indicated that, in all the included studies, the total incidence of DGE〔OR = 0.33, 95%CI is (0.17, 0.63),P = 0.000 9〕, and the time of nasogastric tube〔MD = –2.65，95%CI is (–4.49, –0.80),P = 0.005〕, and time of stared liquid diet〔MD = –4.13, 95%CI is (–7.35, –0.91),P = 0.01〕 showed significant differences. The total incidence of DGE, the time of nasogastric tube, and time of stared liquid diet were less in SSPPD group. But there was no significant difference between the SSPPD group and PPPD group in operating time, intraoperative blood loss, time of started solid diet, hospital stay, and incidences of reinsertion of nasogastric tube, pancreatic fistula, intra-abdominal abscess, reoperation, wound infection, postoperative hemorrhage, and mortality (P>0.05). In the 8 studies adopted DGE standard of ISGPS, the total incidence of DGE〔OR = 0.31, 95%CI is (0.15, 0.65)，P = 0.002〕 and incidence of clinical DGE 〔OR = 0.13，95%CI is (0.05, 0.40),P = 0.000 3〕showed significant differences. The total incidence of DGE and incidence of clinical DGE were both lower in SSPPD group. Conclusions Compared with PPPD group, SSPPD group was associated with significantly less incidence of DGE. Meanwhile, the time of the nasogastric tube and started liquid diet are shorter than those of SSPPD. And there is no significant difference in the other aspects.
