Obstructive Uropathy Secondary to Ureteral Herniation in a Pediatric En Bloc Renal Graft

Ureteral herniation is a rare entity. We report the first case of extraperitoneal ureteral herniation in a pediatric en bloc renal graft causing obstructive uropathy. A 70-year-old, obese patient with an en bloc renal transplant was found to have ureterohydronephrosis in the right renal graft on magnetic resonance imaging. Nephrostomy with insertion of a double-J catheter confirmed the presence of a ureteral loop within the inguinal tract. Surgery confirmed herniation of the ureter through the internal inguinal ring, crossing over the spermatic cord. We performed release, resection, ureteral reimplantation and hernioplasty. Four months later, renal function was normal and urinary tract dilation had diminished. This case illustrates an unusual cause of obstructive uropathy in a transplanted kidney. Apart from obesity, two other factors may have contributed to its development: presence of a redundant ureter, and the fact that the ureter had been placed over, rather than under, the spermatic cord.     

Spigelian hernias: a prospective analysis of baseline parameters and surgical outcome of 34 consecutive patients

Most of the papers published on spigelian hernia are either case reports or small retrospective series. In this prospective multicenter study, we aimed to outline the specific features of spigelian hernias and patients’ characteristics more clearly. Surgeons enrolled patients to be entered into the database as they diagnosed and treated the hernias at will. The baseline and surgical outcome parameters were noted in each patient. A painful mass was the main presenting complaint in half of 34 patients. Accurate preoperative diagnosis was possible in 31 patients. Open intraperitoneal mesh repair was the preferred technique. The mean hospital stay and time until return to normal daily activities were 4.1 and 15.6 days. Although a rare condition, diagnosis of a spigelian hernia is not difficult once remembered. Its surgical repair seems to cause few complications and is very well tolerated by the patient.     

Ipsilateral Aymand’s and Richter’s hernia, complicated by necrosing fascitis

This study presents the case of a patient with necrobiosis or necrosing fascitis of the inguinal region, secondary to a complicated Amyand’s hernia with a concomitant ipsilateral Richter’s hernia. The patient was treated with open trans-abdominal surgery and hernia repair through the pre-peritoneal approach, plus anti-microbians, and thrice-daily wound cleansing and dressings to the inguinal region. Evolution was satisfactory. There are no reports in the literature of a case such as this.

硬膜外穿刺针外套管在腹腔镜小儿斜疝高位结扎术中的应用

目的探讨硬膜外穿刺针外套管在腹腔镜小儿斜疝疝囊高位结扎中的应用价值。方法2003年4月-2006年5月,我院对230例小儿斜疝手术应用硬膜外穿刺针外套管代替雪橇钩针实施腹腔镜疝内环口荷包高位结扎术。结果230例手术均获得成功,手术时间：单侧161例8-10 min,嵌顿疝39例15-20 min,双侧30例16-20 min;术后未见有阴囊水肿及睾血疼痛及缺血坏死。术后随访2-6个月111例,6-12个月52例,12-24个月37例,24-36个月30例,无复发。结论硬膜外刺针外套管可替代小儿疝囊结扎专用的雪橇钩针,简便,经济,适合在所有基层医院推广。     

彩色多普勒超声诊断先天性膈疝的产前分析

目的：探讨先天性膈疝的产前超声表现。材料和方法：回顾性分析6例先天性膈疝胎儿声像图表现特征,并与病理结果相对照。结果：左侧膈疝5例,右侧膈疝1例,其中2例伴有其它复杂畸形。超声显示胎心、纵隔受压移位,心轴偏移明显。疝入器官见有胃泡、肠管、肝脏,胎儿呼吸样运动可致疝入器官运动幅度增加。结论：先天性膈疝的特征性声像图表现,可作为诊断的重要依据。     

全腹膜外补片植入术中补片不固定的实验研究

目的评价全腹膜外补片植入术中补片不固定的安全性和有效性。方法将50只SD大鼠建立疝缺损(3cm2)模型,按随机数字表分为2组,使用聚丙烯补片(12 cm2)采用腹膜外补片植入术进行修复。甲组为补片固定组,乙组为补片不固定组。大鼠于术后不同时间分批处死,记录补片的挛缩度、腹壁抗张强度以及组织细胞学变化。结果所有大鼠术后腹腔均无粘连。2组大鼠在术后7 d、14 d、30 d、60 d和90 d补片的挛缩度分别为6.7%±1.3%vs 7.3%±1.5%、12.3%±1.3%vs 12.4%±1.6%、14.0%±2.0%vs 14.5%±1.3%、17.4%±2.1%vs 18.4%±1.5%和18.9%±2.2%vs19.5%±2.6%(P>0.05);2组大鼠的腹壁抗张强度分别为(288.4±8.4)mm Hg vs(286.6±10.2)mm Hg、(300.4±11.2)mm Hg vs(298.8±11.4)mm Hg、(305.0±11.7)mm Hg vs(303.3±16.1)mm Hg、(309.0±10.8)mm Hg vs(307.6±8.9)mm Hg和(311.8±9.8)mm Hg vs(310.0±8.6)mm Hg(P>0.05);2组大鼠的组织细胞学变化一致。结论当补片面积是大鼠疝缺损的4倍以上时,不固定的腹膜外补片植入术是安全有效的。     

Decision analysis model of incisional hernia after open abdominal surgery

Background The incidence rate of incisional hernias after open surgery has been reported to be higher than that of port site hernias after laparoscopic surgery. No studies have compared the costs for the health care system in treating those two types of hernia. Methods A systematic review was conducted to obtain the baseline data, and a decision analysis model was created to simulate the occurrence and recurrence of incisional and port site hernias. Results The overall risk of having incisional hernias was eight-times higher than that of having port site hernias (7.4% vs 0.9%). A cost savings of ￡93 per patient can be generated for the health care system in the UK. Similar results were obtained for Germany, Italy and France. Conclusions The additional treatment costs for incisional hernia should be taken into account when the costs of a surgery performed by open approach are compared with by laparoscopy.     

Inguinal hernia is a common complication in lower midline incision surgery

Inguinal hernia is a known complication after radical retropubic prostatectomy (RRP). We have investigated whether other types of lower midline incision surgery in males increase the risk of inguinal hernia. Male patients operated with open prostatectomy for benign prostate hyperplasia (n = 95), pelvic lymph node dissection for staging of prostate cancer (n = 88), or cystectomy for bladder cancer (n = 76) were identified and were sent questionnaires in which they were asked about postoperative inguinal hernia morbidity. Two-hundred and seventy-one men operated with RRP had previously received a similar questionnaire. The answers were compared with those from a control group of 953 men who had not undergone surgery. Annual attributional hernia morbidity and Kaplan–Meier hernia-free survival were calculated. The cumulative incidence of post-operative inguinal hernia and annual attributional hernia morbidity after the respective surgical procedures were clearly higher during the early years post-operation than for nonoperated patients. Inguinal hernia is a common postoperative complication in males after all the lower midline incision surgery investigated.
