Paediatric dacryocystorhinostomy

Of 258 cases of dacryocystorhinostomy performed on children in the period September 1981 to September 1991, 130 were for simple, unresolved congenital nasolacrimal duct obstruction. Other indications for surgery included punctal agenesis, lacrimal fistula, post-traumatic and post-inflammatory canalicular obstruction. Of 177 children without canalicular pathology, 171 (96%) were relieved of symptoms with one operation, without canalicular intubation. Of 81 cases with canalicular disease, 55 of 70 (79%) who underwent DCR plus canalicular intubation, and 10 of 11 who underwent DCR plus Lester-Jones tube, were substantially improved with one operation. No child required peroperative or postoperative blood transfusion. Dacryocystorhinostomy in childhood, in experienced surgical hands, is a safe procedure, achieving relief of symptoms in most cases, particularly in the absence of canalicular disease.

Dysgeusia related to urinary obstruction from benign prostatic disease: a case control and qualitative study

Anecdotal reports suggest that dysgeusia may be related to a variety of systemic factors, including bladder outflow obstruction. This is a hospital-based case-controlled study involving 111 patients who were admitted to urological wards for transurethral resection of the prostate for benign prostatic disease with age- and sex-matched control of 137 subjects. We used a semi-structured questionnaire by a trained interviewer at admission (preoperative), at the postoperative period and at follow-up between 4–6 months (median 5 months). Analysis used unpaired t-test and X₂ test. The incidence of dysgeusia was 22% in the study group and 13% in the control group (P=N.S.). However, strikingly, the dysgeusia in the study group was relieved promptly by relief of urinary obstruction in 100% of cases and did not return within the follow-up period. The mechanism of the dysgeusia associated with dysuria in benign prostatic disease is unknown, but we suggest that the dysgeusia could be from the stress of dysuria or due to a release of an unknown chemical from the urinary tract or an overflow of neural impulse from pontine/cortical micturition centres to the taste centres. An association between dysgeusia and dysuria has not been described before.     

Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.     

小肠内固定术治疗粘连性肠梗阻

目的评价小肠内固定术治疗粘连性肠梗阻的疗效。方法回顾性分析28例粘连性肠梗阻行小肠内固定术患者的临床资料。结果28例患者中有5例发生切口感染,无手术死亡和小肠瘘发生。其中25例患者平均随访23.6个月,1例肠梗阻复发,保守治疗后好转。结论小肠内固定术是治疗预防粘连性肠梗阻可行、有效的方法,但需要注意手术操作细节。     

输尿管镜在输尿管梗阻中的诊治价值

目的探讨输尿管镜在输尿管梗阻诊治中的价值.方法应用输尿管镜对52例非结石性输尿管梗阻进行诊治.结果输尿管狭窄35例(行输尿管镜硬性扩张19例,气囊扩张13例,腹腔镜下输尿管成形术3例),输尿管息肉13例行钬激光切除,输尿管癌3例改行开放手术,腔静脉后输尿管1例改行输尿管成形术.手术并发黏膜明显裂伤或黏膜下假道2例,输尿管穿孔1例,其它并发症.结论输尿管镜术能明确输尿管梗阻的病因,并能采取相应治疗.     

腹腔镜胆囊切除术前超声内镜检查胆总管必要性的探讨

目的 探讨腹腔镜胆囊切除（laparoscopic cholecystectomy,LC）术前超声内镜（endoscopic ultrasonography,EUS）检查胆总管的临床价值。方法 对25例术前经腹超声检查诊断胆囊结石,胆总管内径〉0.7 cm可疑胆总管梗阻的患者进行EUS检查,并与手术结果或内镜十二指肠乳头切开术（endoscopic sphincterotomy,EST）取石结果进行比较。结果 EUS对于胆总管病变诊断的敏感性、准确性和阴性预测值[100%（17/17）、92%（23/25）、100%（6/6）]均优于经腹超声[35%（6/17）、56%（14/25）、42%（8/19）]（P=0.000,0.008,0.020）。结论EUS对胆总管病变诊断优于经腹超声检查,可作为术前常规检查,特别是当胆总管内径〉1.0 cm时,EUS应作为术前必检项目。     

腹茧症的影像诊断

目的探讨腹茧症的影像特点，提高术前诊断水平。方法回顾性分析经手术病理证实的腹茧症6例，术前均进行立位腹部X线平片和腹部CT检查，4例同时行胃肠道钡剂造影，复习其影像表现。结果6例立位腹部X线平片中3例诊断为肠梗阻。4例胃肠道钡剂造影，均可见小肠交错盘绕成团，呈“菜花”状或“手风琴”状表现。6例CT检查，均可见小肠聚集成团，其周围可见膜样的囊状物将其包裹。结论对患者进行胃肠道造影时观察到“菜花”状征象，或CT检查时观察到小肠聚集成团被一层膜样物包裹，应考虑到腹茧症的可能。
