颈动脉切除术的临床研究

目的 探讨颈部恶性肿瘤侵犯颈总动脉和I或颈内动脉以及颌面部难控制大出血时对颈总动脉和颈内动脉的外科处理方法及其并发症、后遗症的预防。方法 回顾性分析1990年－2000年行颈总或I和颈内动脉结扎、切除术的6例临床资料。结果 本组均为男性，年龄17－66岁。其中颈部复发性转移癌浸润颈总动脉、颈内动脉3例，鼻咽癌放疗后颈部溃疡侵犯颈总动脉1例，上颌骨中央性血管瘤大出血1例，鼻咽纤维轿管瘤术中、术后大出血1例。单纯结扎、切除颈总动脉4例，颈总及颈内动脉同时结扎、切除2例。经随访，术后短暂性肢体偏瘫2例，脑梗塞、永久性偏瘫1例，无任何并发症3例。无手术死亡病例。结论 颈动脉切除术对已累及颈动脉的颈部恶性肿瘤是一种有效的治疗手段，对于颌面颈难以控制的致命性大出血是一种有效的急救措施。单纯切除颈总动脉所产生的术后并发症的发生率比颈总动脉和颈内动脉同时切除低；而已先期或同时切除颈外动脉，出现并发症的机会更大。术后酌用抗凝或溶栓药物对于脑血栓、脑梗塞的防治作用有待进一步研究。

前列腺增生伴逼尿肌无力患者的电切术治疗

目的 :探讨良性前列腺增生 (BPH)伴有逼尿肌无力 (ACD)患者的治疗方法和效果。方法 :对尿动力学检查确认有ACD的 12例BPH并发膀胱出口梗阻 (BOO)的患者 (A组 )进行经尿道前列腺电切术 (TURP)或加膀胱颈内切开术 (TUIBN) ,同时与逼尿肌功能正常或高于正常的行TURP的BPH患者 2 4例 (B组 )进行对照分析。结果 :A组术后 7～ 30d复查 ,国际前列腺症状评分 (IPSS)为 12 .5 8± 0 .70分 (P <0 .0 0 1) ,最大尿流率 (Qmax)为11.0 5± 0 .85ml/s (P <0 .0 5 ) ,均比术前有改善 ,但术后效果不如B组明显 (P <0 .0 0 1)。术后 3、6个月复查IPSS及Qmax,两组略有改变 ,但差异无显著性意义 (P >0 .0 5 ) ,剩余尿测定也均在正常范围。术后 3个月对ACD的 5例复查逼尿肌收缩力 ,无明显改善。结论 :对ACD并伴有BOO的BPH患者可以采取电切术治疗

INDICATIONS FOR ENDOSCOPIC MUCOSAL RESECTION FOR EARLY COLORECTAL CANCER: SHOULD THEY BE STRICT OR SHOULD THEY BE EXPANDED?

Endoscopic technologies have been developed greatly. As for early gastric cancer, the indications for endoscopic mucosal resection for early colorectal cancer have been widened recently. Technological advances can support wider and deeper resections using endoscopy but the remaining problem for the endoscopic management of cancer is lymph node metastasis. I discuss here the indication for endoscopic mucosal resection for early colorectal cancer to bring into focus the risk factors for metastasis to lymph nodes.

Clinical and manometric evaluation of anorectal function following low anterior resection with low anastomotic line using an EEA™ stapler for rectal cancer

Anorectal function was evaluated in eight patients who had low anterior resection of the rectum with a low anastomotic line, using an EEA^™ stapler, with determination of function based on periodic manometric studies and clinical symptoms. Immediately following surgery all patients suffered from frequent bowel actions and soiling. These symptoms improved with time and most patients could enjoy almost normal daily life by the sixth postoperative month. One month after surgery, anal canal resting pressure and maximum squeeze pressure were significantly reduced and rectoanal inhibitory reflex was absent; neither showed a distinct tendency to improve thereafter. Rectal sensation and reservoir capacity, which also were seriously impaired, recovered satisfactorily by the time of the six-month examination. This suggests that an improvement of clinical symptoms following this operation is dependent upon the recovery of reservoir capacity and sensation of the neorectum, and that this operative procedure is a functionally acceptable option for low rectal cancer.

ENDOSCOPIC SUBMUCOSAL DISSECTION FOR RECURRENT GASTRIC TUMORS

Endoscopic resection has been accepted as the standard treatment for intramucosal gastric tumors of differentiated type. However, the indication was limited to small tumors to achieve en bloc resection and prevent local recurrence in cases of conventional endoscopic mucosal resection (EMR) such as the strip biopsy and the cap technique. To avoid multi‐fragmental resection, we have developed endoscopic submucosal dissection (ESD) as a new endoscopic resection technique. ESD is a remarkable technique, because we make it possible to remove the lesions en bloc regardless of size, shape, coexisting ulcer, and location. However, it is difficult or impossible to resect recurrent tumors en bloc in conventional EMR owing to hard fibrosis, and some patients need laparotomy. Using ESD, we can dissect the submucosal layer as we directly look at the submucosa, and remove the lesion safely and reliably even in cases of hard fibrosis. The key to treatment of recurrent tumors in ESD are as follows: (i) using enough submucosal injection solution (we use a mixture of Glyceol and 1% 1900 kDa hyaluronic acid preparation); (ii) incising the mucosa without fibrosis; (iii) understanding characteristics of various cutting devices, and changing other devices in difficult situations. In these ways we can remove the majority of the recurrent tumors en bloc. Hence, we consider that ESD is a very effective treatment which achieves excellent en bloc and complete resection rates and enables patients with intramucosal gastric tumors to a recurrent‐free survival even in recurrent tumors.
