腹腔镜低位直肠癌根治术中应用盆腔腹膜关闭技术的疗效研究

目的:探讨盆腔腹膜关闭技术在腹腔镜低位直肠癌根治术应用的疗效。方法:回顾性分析2012年1月至2016年5月我院54例腹腔镜低位直肠癌根治术中行盆底腹膜关闭患者和57例未行盆底腹膜关闭患者的临床资料。结果:盆腔腹膜关闭组与盆腔腹膜未关闭组在手术时间、术中出血量、肛门排气时间、术后进食时间以及盆腔引流管拔除时间等方面差异均无统计学意义(P>0.05)。盆腔腹膜关闭组中8例患者发生短期并发症;6例患者发生中期并发症;14例患者发生远期并发症,均为肠梗阻。盆腔腹膜未关闭组中31例患者发生短期并发症,28例患者发生中期并发症,36例患者发生远期并发症。所有患者均治疗好转。Coxs回归模型分析提示,盆腔腹膜是否关闭是腹腔镜低位直肠癌根治术患者术后生存的独立指标。结论:腹腔镜Miles术中行盆底腹膜关闭安全可行,具有临床实用价值。     

Effect of patent ductus arteriosus on the heart in preterm infants

There continues to be controversy on the long‐term effects of a patent ductus arteriosus (PDA) and its management. However, the hemodynamic effects of a large PDA in a preterm infant are well known. This article aims to provide insight into the adaptive changes and remodeling effects of a PDA on the myocardium in preterm infants.     

Over‐the‐scope clip system: A review of 1517 cases over 9 years

Rescue therapy for gastrointestinal (GI) refractory bleeding, perforation, and fistula has traditionally required surgical interventions owing to the limited performance of conventional endoscopic instruments and techniques. An innovative clipping system, the over‐the‐scope clip (OTSC), may play an important role in rescue therapy. This innovative device is proposed as the final option in endoscopic treatment. The device presents several advantages including having a powerful sewing force for closure of GI defects using a simple mechanism and also having an innovative feature, whereby a large defect and fistula can be sealed using accessory forceps. Consequently, it is able to provide outstanding clinical effects for rescue therapy. This review clarifies the current status and limitations of OTSC according to different indications of GI refractory disease, including refractory bleeding, perforation, fistula, and anastomotic dehiscence. An extensive literature search identified studies reported 10 or more cases in which the OTSC system was applied. A total of 1517 cases described in 30 articles between 2010 and 2018 were retrieved. The clinical success rates and complications were calculated overall and for each indication. The average clinical success rate was 78% (n = 1517) overall, 85% for bleeding (n = 559), 85% (n = 351) for perforation, 52% (n = 388) for fistula, 66% (n = 97) for anastomotic dehiscence, and 95% (n = 122) for other conditions, respectively. The overall and severe OTSC‐associated complications were 1.7% (n = 23) and 0.59% (n = 9), respectively. This review concludes that the OTSC system may serve as a safe and productive device for GI refractory diseases, albeit with limited success for fistula.     

Endoscopic vacuum assisted closure of esophagogastric anastomosis dehiscence:A case report

BACKGROUND Esophagogastric leakage is one of the most severe postoperative complications.Partial disruption of the anastomosis,can be successfully treated with an endoscopic vacuum assisted closure(E-VAC).The advantage of that method of treatment is the ability to adjust a vacuum dressing individually to the size of the dehiscence and thus to reduce the risk of a secondary fistula or abscess.The authors present two patients with postoperative gastroesophageal leakage treated successfully with E-VAC.CASE SUMMARY Two male patients developed a potentially life threatening esophagogastric leakage.Patient A underwent resection of the distal half of the esophagus and upper part of the stomach due to Siewert type II adenocarcinoma of the gastroesophageal junction.Proximal resection of the stomach was performed in the patient B after massive bleeding from Mallory-Weiss tears.Both patients were treated successfully with an individually adapted E-VAC with concomitant correction of fluid and electrolyte disturbances,and treatment of sepsis with appropriate antibiotics.CONCLUSION Endoscopic vacuum closure is an effective alternative to endoscopic stenting or relaparotomy.Through individual approach it allows a more accurate assessment of healing.     

Comparison of transcatheter versus surgical closure of perimembranous ventricular septal defect in pediatric patients: A systematic review and meta-analysis

ObjectivePerimembranous ventricular septal defect (pmVSD) is a common congenital heart disease (CHD) usually treated with either catheter or surgical closure. Superiority of one procedure over the other in children is still a matter of debate. We performed this meta-analysis to compare the clinical outcomes and cost of transcatheter and surgical closure of pmVSD in children.Materials and methodsWe searched seven databases (MEDLINE, PubMed, EMBASE, Google Scholar, CENTRAL, CINHAL, and Cochrane library) and literature references for articles published in the past 10 years (between January 2008 and January 2018) comparing closure of pmVSD by both procedures in children. The outcomes of interest were success rate, residual shunt, need for blood transfusion, complications especially complete atrioventricular block, length of hospital stay, and cost.ResultsA total of 1750 articles were identified. However, only five studies fulfilled the inclusion criteria. As regards success rate, no significant difference was found between surgical and catheter closure. Residual shunt was significantly lower in catheter closure than surgical closure [risk ratio (RR) = 0.44; 95% confidence interval (CI), 0.23–0.83, p = 0.01). The need for blood transfusion and the length of hospital stay were significantly lower in the catheter closure compared to surgical closure (RR = 0.02; 95% CI, 0.01–0.08; p < 0.00001), (RR = ?4.81; 95% CI, ?7.76 to ?1.86; p = 0.001), respectively. However, overall complications, complete atrioventricular block, and the cost were comparable in both procedures.ConclusionTranscatheter closure of pmVSD in children was as effective as surgical closure with a lower residual shunt and need for blood transfusion, and shorter hospital stay.
