Resection of recurrent cervical cancer after total pelvic exenteration

The objective of this study was to describe the management of patients with recurrent cervical cancer after total pelvic exenteration (TPE). We reviewed the records of patients who underwent TPE for recurrent cervical cancer between June 1992 and December 2003 and subsequently developed recurrent disease. Thirty-seven patients underwent TPE during the study period, and 25 (68%) subsequently developed recurrence proven by radiographic and/or biopsy studies. Recurrence sites included pelvic (12), inguinal (5), retroperitoneal (5), hepatic (4), vulva (2), perineum (1), transposed ovary (1), and lung (1). The median time to recurrence was 7 months (range 2-73 months), with 92% (23/25) occurring within 2 years of TPE. Management of recurrence was known in 21 of 25 patients, which included chemotherapy (10), surgical resection (7), and no further treatment (4). Surgically resected recurrences were isolated to the groin (2), vulva (2), perineum (1), transposed ovary (1), and psoas muscle (1). The four patients who underwent ovarian, perineal, and vulvar resections succumbed to their disease in a median time of 13 months (range 2-21 months). Of the two patients with surgically resected groin recurrences, one is alive with disease 21 months after initial recurrence and the other is alive without evidence of disease 85 months later. One patient had an isolated 4-cm recurrence involving the psoas muscle and the femoral nerve and is without the evidence of disease 9 months later. Resection of isolated recurrences after TPE is a reasonable option in selected patients, particularly in those with solitary inguinal metastases.     

经尿道前列腺电切术后排尿困难24例分析

目的探讨经尿道前列腺电切术后排尿困难的原因和防治方法。方法对24例经尿道前列腺电切术后出现排尿困难的良性前列腺增生患者的临床资料进行分析。结果术后排尿困难由尿道炎性水肿引起者9例,膀胱颈部狭窄4例,前尿道狭窄3例,前列腺腺体残留4例,血块或前列腺组织块阻塞3例,膀胱逼尿肌收缩无力1例。根据不同的原因分别采取抗炎、留置尿管、尿道扩张、再次经尿道电切或清除膀胱内血凝块或前列腺组织块等处理,效果满意。结论经尿道前列腺电切术后排尿困难可由多种原因引起,查明梗阻原因并根据病因采取相应治疗措施可获满意疗效。     

小儿急性肠套叠肠切肠吻合术42例

目的总结行肠切除肠吻合术的小儿急性肠套叠的诊断和治疗经验。方法对42例行肠切肠吻合术的肠套叠患儿的临床资料进行回顾性分析。结果肠套叠78．57％为复套叠，多为回回结型。大多数术后愈合良好。结论小儿急性肠套叠关键是早期诊断、及时治疗。术中发现肠坏死应尽量减少切除范围，保留回盲部。     

The infra-optic course of the anterior cerebral arteries: an anatomic case report

Although variations of the anterior part of the cerebral arterial circle of Willis are quite well known, though some anomalies are exceedingly rare. In a 61-year-old female individual, on both sides the precommunicating parts of the anterior cerebral artery were found to course inferiorly to the ipsilateral optic nerves. This anomaly was associated with an agenesis of a left posterior communicating artery. The anatomic features, the possible high prevalence of associated aneurysms of the anterior communicating artery complex as well as implications for surgical planning or endovascular treatment are outlined and embryologic considerations and discussed.     

经鼻内窥镜选择性鼻中隔粘膜下切除术

目的：探讨经鼻内窥镜选择性鼻中隔粘膜下切除术的意义及手术方法。方法：根据不同的手术目的对204例需要行鼻中隔手术的病人，经鼻内窥镜实施选择性鼻中隔粘膜下切除术。结果：采用该技术对单纯性鼻中隔偏曲患者手术临床治愈率100％，其手术有效治愈头痛、鼻阻及鼻出血等鼻中隔偏曲临床症状，达到临床治疗目的。未出现鼻腔粘连、鼻中隔穿孔等并发症。有2例形成鼻中隔血肿，经放置引流管处理后治愈。对于解除高位鼻中隔偏曲解剖异常引发的鼻窦炎，手术后效果良好。取鼻中隔软骨做为修补材料手术效果满意。结论：经鼻内镜选择性鼻中隔粘膜下切除术目的性强、方法灵活、创伤小、并发症少、手术效果确切。
