目的观察持续冲洗负压引流技术在腹部外科应用的临床效果。方法回顾性分析2006年1月至2011年3月期间我院将自制双套管实施持续冲洗负压引流技术应用于172例腹部外科患者的临床资料。结果全部患者的消化道瘘均治愈，瘘道愈合的平均时间为36 d。治疗过程中，1例患者出现上消化道出血，另1例出现腹腔出血，无腹腔感染、皮肤破溃感染、脓毒症等并发症。结论采用持续冲洗负压引流的双套管制作简单，经济有效，在腹部外科中对术后肠瘘、出血、胆汁漏及感染的防治具有重要临床意义。
目的 探讨胰十二指肠切除术后胰瘘引起腹腔大出血行外科治疗的可行性。方法 在343例行胰十二指肠切除术的患者中，2例术后发生严重的胰瘘伴有腹腔大出血，均再次手术行胰肠分离式桥式内引流术。结果 经术后支持治疗、持续腹腔冲洗、抑制胰酶分泌，治疗成功，顺利出院。术后随访18个月，没有胰管梗阻和脱落的迹象。患者没有发生糖尿病。结论 胰十二指肠切除术后胰瘘导致的腹腔大出血治疗非常困难，通过外科再手术行胰肠分离式桥式内引流术，取得成功，避免了复杂的全胰切除，挽救了胰腺功能，提高了患者的成功救治机会，改善了患者术后的生活质量。
ObjectiveTo introduce the current status of clinical application, value and perspective of fiberoptic ductoscopy.MethodsThe related literatures on advances in clinical application of fiberoptic ductoscopy were reviewed.ResultsFiberoptic ductoscopy is now widely used in breast diseases, especially complicated with nipple discharge, and it has a higher accuracy rate than routine examinations. With ductoscopy, ductal lavage,location, biopsy and treatment can be carried out.ConclusionFiberoptic ductoscopy has a greater value in diagnosis and treatment, we believe it will be better applied and further developed.
Objective To report the preliminary results of intraoperative saline-irrigated radiofrequency modified maze procedure for chronic atrial fibrillation (AF) in mitral valve diseases. Methods From May 2003 to April 2004 forty-one patients underwent intraoperative saline-irrigated modified maze procedure. The patients included 13 male and 28 female. Their age ranged from 27-65 years (46±10 years). The duration of AF varied from 5 months to 15 years (4.5±3.6 years).The left atrial diameter varied from 37-93 mm (54±11mm). There were mitral stenosis 20, mitral regurgitation 1 and mitral stenosis with regurgitation 20 cases. Cardiopulmonary bypass (CPB) was established as usual. Ablation lines were made with Cardioblate (Medtronic, 25-30 W, 180-240ml/h). Having finished right-sided maze procedure, the aorta was cross-clamped and cold crystalloid or blood cardioplegia were used for myocardial protection. Left atrial incision was performed through the interatrial groove. The ablation lines were created to encircle the orifices of the left and right pulmonary veins respectively. The ablation lines were also performed from the left encircling line to the posterior mitral valvular annulus and to the orifice of left atrial appendage respectively. A ablation line was used to connect left and right pulmonary veins circumferential line. Concomitant procedures were performed (there were double valve replacement 10 cases, mitral valve replacement 31 cases, tricuspid annuloplasty 6 cases, removing the left atrial thrombi 6 cases). Results CPB time varied from 71-160 min (105±24 min) and cross-clamping time varied from 32-106 min (62±20 min). The ablation time varied from 4-22 min (11±4 min). One patient died during hospitalization and the death was caused by acute mechanic valve obstruction. During follow-up at discharge and 3 months 35% patients (14/40) were free of AF and the others were not. But at 6 months 67% patients (10/15) were free of AF. Conclusion The intraoperative saline-irrigated radiofrequency modified maze procedure is comparatively simpler and its efficacy is satisfactory.
Objective To investigate the cl inical outcomes of one stage debridement and closed-suction drainage for treatment of infection after lumbar instrumentation. Methods Between June 2002 and March 2008, 12 patients with infection after lumbar instrumentation were treated with one stage debridement and closed-suction drainage, including 9 males and 3females and aging 35-68 years (48.5 years on average). The disease duration varied from 7 days to 183 days (56 days on average). The segments of internal fixation included 7 cases single segment at levels of L4, 5, 4 cases of double segments at levels of L 4, 5, L5, S1 (2 cases), and L3, 4, L4, 5 (2 cases), and 1 case of three segments at levels of L3, 4, L4, 5, L5, S1. Two patients were treated with internal fixator removal. Results The bacterial culture results of intervertebral discs were positive in 8 cases for Staphylococcus aureus and in 3 cases for Enterobacter cloacae, negative in 1 case. Primary healing of incisions were achieved in all cases. Twelve patients were followed up 18-53 months (34.7 months on average). The white blood cell count, erythrocyte sedimentation rate, and C reactive protein significantly decreased after operation, showing significant differences at 15 days after operation when compared with those before operation (P lt; 0.05). No obvious low back pain was observed. Pathological-changed vertebra-space fused. No displacement and breakage of internal fixator occurred; in 2 patients who were given internal fixator removal, no removal of the instrumentation was performed again. The X-ray films showed that the average kyphosis decreased 0.8° at 18 months after operation. At last follow-up, the visual analogue scale score was 2 ± 1, showing significant difference (P lt; 0.05) when compared with that (10 ± 2) before operation. Conclusion One stage debridement and closed-suction drainage therapy is an effective method for treating infection after lumbar instrumentation. The operation is easy and can reduce hospitalization days.
