The role of the endoscopic extraperitoneal approach in large inguinal scrotal hernias

The role of endoscopic extraperitoneal herniorrhaphy (EEPH) in the management of giant scrotal hernias has not been well defined, and the technical details relating to operations on such hernias have not been described. We present our experience with 17 patients undergoing repair of giant scrotal hernias. Foley catheter bladder decompression was routinely employed. The Retzius space was developed early in the procedure and hernia sac contents were reduced in all cases. The inferior epigastric vessels were likewise divided in all patients. The average operative time was 76 min and all patients were discharged home the same day. There have been no recurrences on follow-up. There was no mortality, and morbidity was limited to seroma formation in two patients. We conclude that with certain technical modifications, EEPH can be safely employed for the treatment of giant scrotal hernias. Received: 7 May 1996/Accepted: 12 July 1996     

内镜鼻胆管引流术在腹腔镜和开腹胆总管探查术中的应用

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     

Relationship between the gastric myoelectric and mechanical activity in the genesis of ulcers in indomethacin-insulin-treated rats

We have proposed that gastric contractile activity mechanically induces ulcers in the nonsteroid antiinflammatory drug (NSAID)-treated rat. This study examines first the relationship between number (dose) of peristaltic contractions applied to the mucosa and the ulcer score. Second, it examines the relative roles of: altered gastric myoelectrical activity (MEA) resulting from indomethacin (Indo) pretreatment, insulin-induced gastric peristalsis, and a combination of the two in the generation of mucosal lesions. Third, it examines the effect of exogenous prostaglandin on the Indo-altered MEA and relates it to ulcerogenesis. Indo pretreatment increased gastric tone and MEA. In such animals, the dose of peristaltic contractions applied to the gastric wall was related to the ulcer score in a dose-dependent manner. Exogenous prostaglandin (PG) reversed the MEA effect of Indo and reduced ulceration. It is postulated that an altered smooth muscle state secondary to inhibition of prostaglandin synthesis (PG-S) renders the mucosa vulnerable to injury by peristaltic action.This study was supported by the Fast Foundation.     

Giardia muris infection in mice with concurrent graft-versus-host reaction

The effects of concurrent graft-versus-host reaction (GvHR) on the course of Giardia infection in CBA x BALB/c F1 mice have been examined, to test the hypothesis that T-cell-mediated immunity, in the form of a local DTH reaction, alters the host-parasite relationship in favour of the host by changing the physical environment of the parasite. GvHR did not enhance immunity, indeed mice infected with Giardia at a late stage of GvHR had significantly higher faecal cyst excretion and prolongation of the plateau phase of infection, indicating a degree of immunodeficiency.
