Pleural flap to prevent lobar torsion: a novel technique

Lobar torsion is reported as very rare but sometimes catastrophic complication if overlooked during the early postoperative period following a lobectomy, though it is totally preventable. In this novel technique, a piece of parietal pleural flap is harvested from the posterior wall of the chest using a hook diathermy while keeping its upper border as close to the apex as possible. Finally, distal end of the flap is secured to the upper edge of the lobe using a fine monofilament absorbable suture. This procedure not only protects the lobe from rotation but also maintains continuous expansion of the lung in the early postoperative period and may, therefore, be a good option to prevent such a serious complication in selected patients following a lobectomy.

目的探讨老年骨髓炎患者围术期护理的体会及经验。方法对32例老年骨髓炎患者围术期护理经验进行分析和总结。结果全组32例患者通过手术治疗及合理护理措施均得到治愈，无褥疮、肺部及泌尿系感染等并发症发生。结论老年骨髓炎患者体质差，合并症多，护理需认真、细致，并且根据术前、术中、术后按不同病情制订个案护理计划，预防并发症，能有效地提高手术成功率。     

围手术期抗生素的合理应用

近年来,由于抗生素的滥用导致外科术后感染率明显上升,同时,在医院环境诱导了对抗生素耐药菌株的产生或引起细菌或霉菌的二从感染.为了有效地降低术后感染率,减少抗生素药物的副反应,自2001年1月份开始,我们采用围手术期抗生素的合理运用,与以往同期相比,骨科术后感染率明显下降,副反应减少.……     

Der operierte mechanische Ileus

Zusammenfassung Von 1972 bis 1983 wurden 351 Patienten wegen eines mechanischen Dünndarm- (n = 256) bzw. Dickdarmileus (n = 95) operiert. Die chirurgische Komplikationsrate betrug beim Dünndarmverschluß 28,1 bzw. beim Dickdarmileus 24,3%, wobei am häufigsten Anastomosendehiscen-zen nach Resektionen (17,7% bzw. 53,8%), Enterotomien (5,8%/27,2%), Platzbäuche (3,5%/4,2%) und ein Re-Ileus (5,5%/3,2%) vorlagen. Die internistischen Komplikationen (postop. Pneumonien, Lungenembolien, kardiale Dekompensationen etc.) betrugen 17,9% bzw. 22,1 %. Die perioperative Letalität lag beim Dünndarmileus bei 20,6% und beim Dickdarmileus bei 33,4%. Als Schlußfolgerungen dieser retrospektiven Analyse ergaben sich die frühzeitige, perioperative, intensiv-medizinische Behandlung, die generelle Thrombose-, Pneumonie- und StreBulcusprophylaxe, die exakte, präoperative Röntgendiagnostik, die strenge Indikationsstellung für Enterotomien und Resektionen, das dreizeitige Vorgehen beim linksseitigen Dickdarmileus, die Inkontinuitätsresektion nach Hartmann bei entzündlichen Prozessen im Sigmabereich und die innere Dünndarmschienung bei Peritonitis bzw. ausgedehnten Adhäsionen. Dadurch konnte seit Anfang 1984 die Komplikationsbzw. Letalitätsrate beim Dünndarmileus (n = 64) auf 9,4% bzw. 4,7% und beim Dickdarmileus (n = 20) auf 10% bzw. 5% gesenkt werden.

Experiences with operations of mechanical ileus

Summary Between 1972 and 1983 a total of 351 patients was operated suffering from mechanical occlusion of the small intestine (n = 256) and of the colon (n = 95). The surgical complication rate amounted to 28.1% in cases of small intestine ileus and to 24.3% in cases of colon ileus; the most frequent complications were anastomotic dehiscences following resections (small intestine 17.7%/colon 33.8%), enterotomies (5.8%/27.2%), abdominal wall ruptures (3.5%/4.2%) and re-ileus (5.5%/3.2%). The medical complication rate (postop. pneumonia, pulmonary embolism, cardial decompensation etc.) amounted to 17.7% resp. 22.1%. All these complications carried a mortality of 20.6% in small intestine ileus and of 30.4% in colon ileus. The consequences of this retrospective analysis resulted in: early intensive care treatment, general perioperative thrombosis-, pneumonia- and stress ulcer prophylaxis, exact preoperative radiological diagnosis, strict indications for enterotomies and resections, sole transversostomy in stage of ileus for the left-sided colon obstruction caused by carcinoma, discontinuity resection by Hartmann in cases of inflammatory or perforated large bowel stenoses and tube decompression of the small bowel in cases of peritonitis or wide-spread adhesions. Since 1984 we could prospectively decrease the complication resp. mortality rate of the small intestine ileus (n = 64) to 9.4% resp. 4.7% and of the colon ileus (n = 20) to 10% resp. 5%.

     

围手术期肠外营养支持在胃癌根治术的应用

1986～1988年的胃癌扩大根治术221例及根治性全胃切除术19例非肠外营养(N-TPN)支持为对照组,与1991～1993年的198例及61例施行TPN治疗为实验组进行对比。N-TPN组术后并发症总发生率为7.2％,TPN组则为2.0％;全胃切除术并发症发生率分别为31.6％和4.9％(P<0.01)。吻合口瘘发生率N-TPN组分别为2.7％和10.5％,而TPN组则均为0.0％(P<0.01)。膈下脓肿发生率N-TPN组为31.6％和15.8％,而TPN组则为1.5％和3.3％(P<0.05)。但本研究是回顾性的,所以要有待进行前瞻性的、对照的、随机的大范围研究。     

老年腹主动脉瘤患者腔内隔绝围手术期脑保护

目的探讨老年腹主动脉瘤患者腔内隔绝围手术期脑保护及其临床意义。方法根据有无实施脑保护将69例老年腹主动脉瘤行腔内隔绝治疗的患者随机分成两组:保护组38例,对照组31例。对两组术后脑血管意外及脑功能障碍情况进行对比分析。结果两组的年龄、入院时血压、手术时间差异均无统计学意义。两组均未发生死亡和出血性脑卒中。保护组术后谵妄发生率低于对照组(分别为5.3%和41.9%,P<0.05),术后住院时间少于对照组(分别为9.1±3.2d和16.7±5.8d,P<0.05);术后缺血性脑卒中保护组0例,对照组3例,两组比较无统计学意义(0%和9.7%,P>0.05)。结论对老年腹主动脉瘤接受腔内隔绝治疗的患者围手术期采取脑保护能降低脑血管意外和维持大脑功能,有利于患者术后恢复。     

Diagnosis and management of severe atherosclerosis of the ascending aorta and aortic arch during cardiac surgery: focus on aortic replacement

Objective: Severe atherosclerosis of the ascending aorta and arch frequently causes difficulties during heart operations, hindering surgical manoeuvres and potentially leading to systemic embolism. The aim of our study was to assess the safety and effectiveness of replacing the atherosclerotic ascending aorta in this setting. Methods: Aortic atherosclerosis was characterized by epiaortic ultrasonographic scanning in 90.1% of 1927 consecutive adult patients undergoing cardiac operations, and by computed tomographic chest scanning in selected cases. Thirty-six of the 152 patients requiring major derangements from our standard practice due to aortic atherosclerosis underwent replacement of the ascending aorta and constitute the study group. Replacement of the aorta was extended to the arch in 13 cases (36.1%). It was associated with single or multiple valve surgery in 34 patients (94.4%) and with coronary revascularization in 30 (83.3%). Two patients (5.6%) underwent coronary bypass grafting without valve surgery. A cryoablation procedure was associated in three patients with permanent atrial fibrillation. Deep hypothermic circulatory arrest was employed in 34 patients (94.4%), while proximal aortic disease allowed conventional distal crossclamping in 2 cases. The risk of operative mortality was estimated by the logistic EuroSCORE both with and withholding the variable ‘surgery of the thoracic aorta’. All survivors were followed-up for 1–41 months (16 ± 12). Results: Two patients died in the hospital (5.6%) and two during follow-up, for a cumulative survival of 91.3% and 85.6% at 1 and 3 years, respectively (hospital deaths included). The hospital death rate compared favourably with the expected estimates of 25.5% (p < 0.05) and 10.3% (p = 0.67) obtained by the EuroSCORE full model and without ‘aortic surgery’, respectively. In-hospital adverse neurologic events occurred in six patients (16.7%), including stroke in one patient (2.8%) and neurocognitive disturbances in five (13.9%), although they were all transient and cleared before discharge. Excess bleeding required re-exploration in four patients (11.1%), and one more patient underwent emergency grafting for acute postoperative coronary occlusion. Ten patients (38.5%) were intubated for longer than 24 h. Conclusion: Despite significant perioperative morbidity, replacement of the severely atherosclerotic aorta is worth consideration to avert expectedly higher death and stroke rates.
