食管癌切除术后不同重建途径吻合口瘘的原因及预防

目的了解食管癌切除术后经不同径路重建,发生吻合口瘘的情况;探讨系统性淋巴结清扫后,经胸骨后胃代食管颈部吻合口瘘发生率较高的原因及预防方法。方法1105例行食管癌切除术的患者,229例经左胸行胸内吻合(A组),716例经右胸食管床胃代食管行颈部吻合(B组),160例予以系统性淋巴结清扫术后经胸骨后行颈部吻合(C组)。分析比较不同手术径路的3组患者术后吻合口瘘发生的情况。结果吻合口瘘发生率分别为:A组5/229(2.2%)、B组85/716(11.9%)、C组31/160(19.4%),C组吻合口瘘发生率显著高于A、B组(P<0.01和P<0.05)。比较C组不同重建方式吻合口瘘发生率显示,手工吻合与器械吻合(22.2%与11.6%,P=0.133)、全胃重建与管状胃重建(25%与15.6%,P=0.146)间吻合口瘘发生率无明显差异,而延长胃肠减压管留置时间至术后7d,吻合口瘘发生率由23.3%降至9.1%(P<0.05)。结论胸骨后胃代食管吻合口瘘发生率较高的主要原因,是前纵隔内的胃体受压、冲击吻合口所致;通过延长胃肠减压管留置时间能有效减少瘘的发生。     

龙血竭散在肛瘘术后的临床应用

目的：探讨龙血竭散在肛瘘术后促进创面愈合的疗效和机理。方法：选用50例肛瘘手术病人，分为治疗组（用龙血竭散）和对照组（用雷夫奴尔纱条）各25例，分别观察术后创面换药疼痛和愈合时间。结果：治疗组在减轻创面疼痛，促进肉芽组织生长，加速创面愈合等方面明显优于对照组（P〈0．01）。结论：龙血竭散可明显缩短创面愈合时间，且无瘢痕过度生长，具有临床应用价值。     

体部表面线圈磁共振成像对肛瘘的术前诊断价值

目的:探讨体部表面线圈MRI对肛瘘的术前诊断价值。材料和方法:回顾性分析42例肛瘘患者,均于术前进行非增强MRI检查,将MRI结果与手术结果对照。结果:MRI诊断结果与手术结果一致,其中23例为括约肌间型,5例经括约肌型,5例括约肌上型,9例括约肌外型,所有病例中有12例可见肛周脓肿形成。结论:MRI作为一种安全、准确的肛瘘检查方法,对于肛瘘的术前诊断具有非常重要的价值。     

Transcranial cerebral oximetry and carotid cavernous fistula occlusion

Summary Different methods have been used in the evaluation and monitoring of the cerebral oxygen supply during neuro-interventional therapies. Attenuation of near-infrared light by the chromophores oxyhemoglobin and deoxyhemoglobin have shown to be useful in the study of the cellular oxygen metabolism and oxygen delivery to the brain. Transcranial cerebral oximetry (TCCO) has the advantage of providing real-time information regarding regional brain oxygen saturation (rSO₂) by using wavelengths in the near-infrared range.We present a patient with a carotid cavernous fistula who underwent balloon occulusion and concurrent continuous TCCO monitoring. TCCO was found to be a useful tool providing immediate rSO₂ values during the angiographic and interventional procedures. Initial balloon occlusion of a carotid cavernous fistula resulted in partial occlusion of the internal carotid artery lumen causing an immediate decrease in rSO₂ which correlated with angiographic findings. Subsequent reocclusion of the fistula produced a slower and smaller degree of decrease in rSO₂ with clinical improvement in the patient. Changes in rSO₂ were detected before any adverse clinical event was observed. TCCO was reliable, safe, sensitive, and provided a real-time assessment tool for the monitoring of brain oxygen supply in a patient undergoing a neuroendovascular procedure.

Oesophageal atresia: caudo-thoracic epidural anaesthesia reduces the need for post-operative ventilatory support

The mortality of neonates with oesophageal atresia in the Third World remains high because of delays in presentation and diagnosis. Lack of appropriate intensive care facilities is a further contributing factor. Caudothoracic epidural anaesthesia was used during surgical repair of oesophageal atresia in 35 patients in an attempt to minimise the need for post-operative ventionally support. This group was compared with 36 patients whose surgery was performed under general anaesthesia. The age at the time of referral, sex ratio, and weight were comparable in both groups. Using the Waterson classification, a greater number of poorer prognostic patients were seen in the epidural group (P <0.02). In all Waterson risk categories fewer patients required ventionally support post-operatively, which was statistically significant (P <0.01) when all categories were combined. We are encouraged by our results and believe this technique has a rôle in the management of neonates undergoing major surgery, both where neonatal intensive care exist or is deficient as in many parts of the Third World.

Primary Adenocarcinoma in the Urethrorectal Fistula

A 60-year-old Japanese man was hospitalized because of urinary leakage from the anus on October 3, 1994. Retrograde urethrography detected a fistula between the bulbous urethra and the rectum. Urethrocystoscopy revealed a tumor on the urethrorectal fistula. Tumor biopsy showed a well differentiated adenocarcinoma. Cystourethrectomy with fistulectomy, and ileal conduit urinary diversion were performed. Pathological examination revealed primary adenocarcinoma in the fistula with invasion to the prostatic urethra and bladder wall. The patient showed no evidence of a recurrence as of August, 1996.
