W-pouch With Modified Non-isolated Extra Limb for Continence in Cutaneous Diversion After Radical Cystectomy

OBJECTIVE

To report the functional results of continent cutaneous ileal urinary diversion using modified W-pouch with non-isolated extra limb for continence.

PATIENTS AND METHODS

From January 2013 to January 2016, 21 patients with muscle-invasive bladder cancer with median (interquartile range) of 59 (56.5-62.5) years old underwent radical cystectomy with pelvic lymphadenectomy; they then had an ileal continent cutaneous pouch constructed from W-pouch with non-isolated extra limb for continence. The technique entails the creation of a detubularized ileal W-pouch with extra limb fashioned from 59 cm of the terminal ileum. This extra limb is not isolated from the pouch. The proximal part of this limb is tailored and fixed in a subserous extramural tunnel for continence, whereas the distal part is left continuous with the pouch. The median (interquartile range) of follow up was 12 (8-17) months. Evaluation of the technique included operative time, continence efficiency, overall complications, and quality of life questionnaire for the patients.

RESULTS

The median (interquartile range) of operative time of the operation was 4.7 (3.9-5.4) hours. The median (interquartile range) of operative time of the cutaneous pouch creation was 39 (33-43) minutes. No perioperative mortality had occurred. The incidence of continence was 95.2%. The overall complications were 42.8%, and most of them were grade 1 or 2 on Clavien-Dindo classification system.

CONCLUSION

Modification of W-pouch with non-isolated extra limb as continent cutaneous pouch can simplify the technique and shorten the operative time with efficient continence, less side effects, and good quality of life.

Single versus multiple instillation of povidone iodine and urographin in the treatment of chyluria: A prospective randomised study

Objective

To compare the safety, efficacy and complications of single vs multiple instillations of povidone iodine (PI) and urographin as a sclerosing agent in the treatment of chyluria.

Patients and methods

The study included 58 patients diagnosed with chyluria between March 2006 and January 2013. The inclusion criteria were either severe attacks of chyluria or patients with mild-to-moderate chyluria who had failed conservative treatment. The patients were randomly allocated to one of two groups: those in Group A had a single instillation of a combination of PI 0.2% plus the contrast-agent urographin 76%, while those in Group B had multiple instillations of the same combination twice daily for 3 successive days.

Results

The mean (SD) age of the patients in Groups A and B was 38.22 (10.67) and 37.9 (10.86) years, respectively. Chyluria was severe in eight patients (14.8%), moderate in 25 (46.3%) and mild in 21 (38.9%). The success rate in Group A (single instillation) was 85.2% and in Group B (multiple instillation) was 88.9%. The recurrence rate in Group A was 14.8% with a disease-free duration (DFD) of 4–15 weeks, while in group B it was 11.1% with a DFD of 6–18 weeks.

Conclusion

There was no significant difference between a single instillation of a combination of PI 0.2% and urographin 76% as a sclerosing agent in the treatment of chyluria and multiple instillations. However, the single instillation protocol is more cost effective with a shorter hospital stay.

Efficacy of laparoscopically assisted high ligation of patent processus vaginalis in children

INTRODUCTION

Laparoscopic hernia repairs have been proven to be efficient and safe for children, despite the slightly higher recurrence rate compared with the classic surgical repair. They have the advantage of easy and precise identification of the type of defect and its correction, both in ipsilateral and contralateral sides.

OBJECTIVES

The objectives of this study were to evaluate the efficacy, safety and outcome of the laparoscopically assisted piecemeal high ligation of a patent processus vaginalis (PPV) in children.

METHODS

A total of 40 children were enrolled into this prospective study; they were aged ≥ 6 months and had an inguinal hernia. The peritoneal cavity, including the contralateral side, was inspected for the possibility of bilateral hernias using a 3-mm 30° telescope. Another 3-mm port was introduced through the same infra-umbilical incision. The hernia was manually reduced or with the aid of a working infra-umbilical grasper. A prolene or vicryl 2/0 or 3/0 suture on a curved semicircle round-bodied taper-ended 25-30 mm needle was introduced through a very small inguinal skin-crease incision. It was passed through the abdominal wall layers to the peritoneum and was manipulated by the laparoscopic grasper to pick up the peritoneum in piecemeal all around the internal ring. The needle was then pushed to the outside near to the entrance site, thus forming a semicircle around the internal ring. The suture was then tied and the knot was subcutaneously buried. The primary outcome of the procedure was the incidence of intraoperative diagnosis and surgical repair of contralateral hernias in pre-operatively diagnosed unilateral cases. The secondary outcomes were defined as the incidence of complications and hernia recurrence.

DISCUSSION

The exploratory laparoscopy found contralateral patent processus vaginalis (CPPV) with a detection rate of 28.1%. Chan et al., Esposito et al., Toufique et al. and Niyogi et al. reported similar figures for laparoscopic contralateral hernia detection rates of 28%, 39%, 39.7% and 29.2%, respectively. The limitations of this study were the small sample size, plus the risk factors and clinical significance for CPPV.

CONCLUSION

Laparascopically assisted piecemeal closure of the internal inguinal ring in children is a safe and effective procedure. It helps in detecting a contralateral hernia without prolonging the operative time.

Closure of bladder exstrophy with a bilateral anterior pubic osteotomy: Revival of an old technique

Objective

To evaluate the results of simple closure using bilateral anterior pubic osteotomy to achieve a tension-free approximation of the pubis and abdominal wall in patients with bladder exstrophy.

Patients and methods

A prospective study carried out between 2006 and 2009 included 15 patients (13 boys and 2 girls; age range 3–47 months). Of these patients, three had recurrent exstrophy while 10 were operated primarily. An elective surgical technique was used for all patients, which included dissection of the exstrophic bladder from the abdominal wall, closure of the bladder and reconstruction of the urethra, then dissection of the rectus muscle and sheath lateral to the attachment of muscle to pubic bone, which makes osteotomy of the superior pubic ramus easy, thus facilitating closure.

Results

For closure of the bladder and anterior abdominal wall the results were excellent for all patients soon after surgery, but there was soft-tissue infection in two patients. Of all 15 patients, one had incomplete bladder dehiscence and another had a vesico-cutaneous fistula; both needed surgical intervention later.

Conclusions

Simple closure with anterior pubic osteotomy is a feasible and effective means to facilitate both bladder and abdominal closure for patients with bladder exstrophy. It is advantageous in being a rapid procedure, and can be completed by the paediatric urologist.
