Parastomal hernia after ileal conduit: Incidence, natural history and risk factors.

INTRODUCTION: Parastomal hernias are a challenging complication of digestive ostomies. Ileal-conduit parastomal hernias after cystectomy have specific aspects. The aim of this study was to describe the incidence and natural history of ileal-conduit parastomal hernias in order to guide their management, as well as to identify risk factors to prevent them. PATIENTS AND METHODS: All consecutive patients undergoing cystectomy with a Bricker's ileal conduit in 3 academic centers were retrospectively identified. Data were collected regarding their medical history prior to cystectomy, the operation, the postoperative period, imaging results within 5 years of follow-up, and the onset and timing of clinically or radiologically diagnosed ICPH. RESULTS: Among 577 patients included in the study, 115 (20.6%) developed an ICPH during the study period. Most patients did not present any symptom and the diagnosis was made at imaging in 74.8% of them. Most hernias were detected between 1 and 2 years after the cystectomy, with a mean time to diagnosis of 12.4 months. At multivariate analysis, overweight and obesity were independent risk factors for developing an ICPH (adjusted hazard ratio [aHR] 1.96; p = 0.046), while a trans-rectus position of the ostomy was a significant protective factor (aHR 0.45; p = 0.011). CONCLUSIONS: A PH develops in almost 20% of patients after ileal conduit urinary diversion, with a mean time of onset of 12.4 months. It is often a subclinical condition detected at medical imaging. Obesity increases the risk, while passing the ileal-conduit through the rectus muscle can help to prevent it.

Combined Robotic and Vaginal Surgery for Pelvic Exenteration Due to Vaginal Sarcoma Relapse in an Obese Woman.

STUDY OBJECTIVE: Pelvic exenteration (PE) is an aggressive surgical procedure that implies a large hard-to-fill pelvic defect. Different reconstruction techniques were proposed to improve abdominal organ support and reduce complications (infections, pelvic organs herniation, vaginal stump dehiscence, bowel prolapse and obstruction) [1], with conflicting results [2]. Because of young age and survival greater than 50% at 5 years in patients with no residual tumor after surgery [3], a new approach with better clinical results to pelvic reconstruction is needed. DESIGN: The aim of this surgical film is to present an unusual presentation of vaginal sarcoma, successfully managed with a minimally invasive approach, and to illustrate our contextual multilayer technique of pelvic reconstruction using a combination of pedicled omental flap (POF) and human acellular dermal matrix (HADM). SETTING: Tertiary level academic hospital. A 42-year-old obese patient with recurrent and symptomatic myxoid leiomyosarcoma, previously underwent vaginal-assisted laparoscopic surgery at a primary care center for the removal of a vaginal swelling. INTERVENTIONS: The multidisciplinary board determined anterior PE as the optimal therapeutic approach. Given the patient's body mass index (33 kg/m2), young age, and the favorable outcomes of robotic surgery in obese patients compared with other approaches [3,4], we proposed a combined robotic and vaginal surgery for both exenteration and reconstructive procedures [5]. During surgery, we initially explored the abdominal cavity to exclude macroscopic metastasis, followed by anterior PE. Urinary diversion was achieved with a Bricker ileal conduit by means of an ileoileal laterolateral anastomosis and an uretero-ileo-cutaneostomy. The pelvic dead space was partially filled with a POF on the left gastroepiploic artery. Subsequently, the pelvic defect was covered by a 15 × 10 mm HADM inlay inserted circumferentially at the pelvic brim, fixed with a barbed thread suture on residual pelvic structures. The final pathology confirmed the recurrence of myxoid leiomyosarcoma and indicated tumor-free resection margins. The intraoperative and postoperative periods were uneventful. The patient was discharged 14 days after surgery and underwent adjuvant doxorubicin- and dacarbazine-based chemotherapy, which was initiated 45 days after the surgery. Currently the patient is asymptomatic and disease free at the sixth month of follow-up. CONCLUSION: Robotic PE proves to be a feasible technique in obese patients, reducing postoperative hospital stay and complications. The contextual pelvic floor reconstruction with a POF and HADM supports abdominal viscera, diminishing interorgan adhesions and bowel prolapse. VIDEO ABSTRACT.

Bricker versus Wallace ureteroileal anastomosis: A multi-institutional propensity score-matched analysis.

AIM OF THE STUDY: The aim of our study is to evaluate the difference in stricture rate between matched groups of Bricker and Wallace techniques for ureteroileal anastomosis. PATIENTS AND METHODS: A retrospective analysis of patients undergoing urinary diversion (UD) with Bricker and Wallace ureteroileal anastomosis at two university hospitals. Two groups of Bricker and Wallace patients were matched in a 1:1 ratio based on the age, sex, body mass index (BMI), Charlson comorbidity index (CCI), preoperative hydronephrosis, prior radiation therapy or abdominal surgery, pathologic T and N stages and 30-days-Clavien grade complications≥III. A multivariable Cox regression analysis was conducted to identify predictors of ureteroenteric stricture (UES) in all patients. RESULTS: Overall, 740 patients met the inclusion criteria and 209 patients in each group were propensity matched. At a similar median follow-up of 25 months, UES was detected in 25 (12%) and 30 (14.4%) patients in Bricker and Wallace groups, respectively (p = 0.56). However, only one patient in the Bricker group developed a bilateral stricture compared to 15 patients in the Wallace group, resulting in a significantly higher number of affected renal units in the Wallace group: 45 (10.7%) versus only 26 (6.2%) in the Bricker group (p = 0.00). On multivariable extended Cox analysis, prior radiotherapy, presence of T4 pelvic malignancy and nodal positive disease were independent predictor of UES formation. CONCLUSION: The technique of ureteroileal anastomosis itself does not increase the rate of stricture; however, conversion of two renal units into one is associated with a higher incidence of bilateral upper tract involvement.

Prophylactic surgical mesh placement as a prevention of parastomal hernia in open radical cystectomy with ileal conduit diversion - pilot study.

INTRODUCTION: This study examines the efficacy of prophylactic mesh implantation during open radical cystectomy with ileal conduit diversion in preventing parastomal hernias (PH). Despite PH being a common complication, prophylactic methods have been underexplored. METHODS: A pilot, single-center, prospective cohort study was conducted involving five patients undergoing surgery with mesh implantation. Demographic and clinical characteristics were monitored, including the incidence of PH, operation time, blood loss, and hospitalization duration. RESULTS: During the mean follow-up period of 9.1±3.2 months post-operation, no occurrences of PH were observed in the patient group. Despite the risks associated with implanting foreign material in an area of surgery involving open small intestine, no infectious complications were noted. CONCLUSION: Prophylactic mesh implantation in radical cystectomy with ileal conduit diversion appears to be an effective preventive measure against PH. Further extensive studies are required to definitively confirm the efficacy and safety of mesh use in this context.

Surgical management of parastomal hernia following radical cystectomy and ileal conduit: A french multi-institutional experience.

BACKGROUND: Parastomal incisional hernia (PH) is a frequent complication following the creation of an ileal conduit (IC), and it can be a significant detriment to quality of life. The aim of this study was to evaluate outcomes of PH repair following IC for urinary diversion. METHOD: A multicenter retrospective study was conducted of 6 academic hospitals in France. The study's population included patients who underwent surgical treatment for parastomal hernia following IC creation from 2013 to 2021. RESULTS: Fifty-one patients were included in the study. Median follow up was 15.3 months. Eighteen patients presented with a recurrence (35%), with a median time to recurrence of 11.1 months. The vast majority of PH repair was performed through an open approach (88%). With regard to technique, Keyhole was the most reported technique (46%) followed by Sugarbaker (22%) and suture only (20%). The Keyhole technique was associated with a higher risk of recurrence compared to the Sugarbaker technique (52% vs 10%, p = 0.046). Overall, there was a 7.8% rate of major complications without a statistical difference between PH repair techniques for major complications. CONCLUSION: Surgical treatment of parastomal hernia following IC was associated with a high risk of recurrence. Novel surgical approaches to PH repair should be considered.

How-I-do-it: minimally invasive repair of ileal conduit parastomal hernias.

BACKGROUND: Parastomal hernia after radical cystectomy and ileal conduit urinary diversion is an underestimated and undertreated condition with significant impact on quality of life. However, its surgical treatment is challenging and prone to complications and the optimal surgical treatment of this condition remains to be determined. METHODS: In this article, we describe our surgical techniques in the minimally invasive treatment of ileal conduit parastomal hernia and present our preliminary results. In a retrospective single-center design, a prospectively maintained database was screened. Data from all patients undergoing surgical treatment for a parastomal hernia after cystectomy and ileal conduit urinary diversion in our center were collected. RESULTS: Between May 2016 and June 2020, 15 patients underwent minimally invasive repair of a parastomal hernia of an ileal conduit. Details on the surgical approach are provided, along with a flow chart to standardize the choice of surgical technique, depending on the presence of a concomitant midline incisional hernia and perioperative findings. The majority of patients were treated with robotic-assisted laparoscopic surgery (10/15; 66.7%). Median postoperative hospital stay was 5 days. One-third of patients developed a postoperative urinary infection. Median follow-up was 366 days. One patient developed a local recurrence of her parastomal hernia on day 66 postoperatively, treated with intraperitoneal mesh. CONCLUSION: The minimally invasive surgical treatment of a parastomal hernia after ileal conduit urinary diversion poses specific perioperative challenges that require a broad surgical armamentarium and a tailored approach. Preliminary results confirm a significant morbidity after this type of surgery.

Comparative analysis of Bricker versus Wallace ureteroenteric anastomosis and identification of predictors for postoperative ureteroenteric stricture.

PURPOSE: Ureteroenteric anastomosis after cystectomy is usually performed using the Bricker or Wallace technique. Deterioration of renal function is the most common long-term complication of urinary diversion (UD). To improve surgical care and optimize long-term renal function, we compared the Bricker and Wallace anastomotic techniques and identified risk factors for ureteroenteric strictures (UES) in patients after cystectomy. MATERIAL AND METHODS: Retrospective, monocentric analysis of 135 patients who underwent cystectomy with urinary diversion at the University Hospital Essen between January 2015 and June 2019. Pre- and postoperative renal function, relevant comorbidities, prior chemo- or radiotherapy, pathological findings, urinary diversion, postoperative complications, and ureteroenteric strictures (UES) were analyzed. RESULTS: Of all 135 patients, 69 (51.1%) underwent Bricker anastomosis and 66 (48.9%) Wallace anastomosis. Bricker and Wallace groups included 134 and 132 renal units, respectively. At a median follow-up of 14 (6-58) months, 21 (15.5%) patients and 30 (11.27%) renal units developed UES. We observed 22 (16.6%) affected renal units in Wallace versus 8 (5.9%) in Bricker group (p < 0.001). A bilateral stricture was most common in Wallace group (69.2%) (p < 0.001). Previous chemotherapy and 90-day Clavien-Dindo grade ≥ III complications were independently associated with stricture formation, respectively (OR 9.74, 95% CI 2-46.2, p = 0.004; OR 4.01, 95% CI 1.36-11.82, p = 0.013). CONCLUSION: The results of this study show no significant difference in ureteroenteric anastomotic techniques with respect to UES development regarding individual patients but suggest a higher risk of bilateral UES formation in patients undergoing Wallace anastomosis. This is reflected in the increased UES rate under consideration of the individual renal units.

[How do patients manage their urostomy in everyday life? A questionnaire survey]. / Comment les patients prennent-ils en charge leur urostomie au quotidien ? Enquête par questionnaires.

INTRODUCTION: The complications of stoma and peristomal are encountered by nearly 80% of patients within two years of surgery. The objective of this study was to evaluate the practical modalities of daily management of stoma and possible skin complications in a series of patients with non-continent urinary stoma. METHODS: Monocentric study by questionnaires including all patients with non-continent urinary stoma between 2007 and 2019 in a French university center. The STOMA-QOL and a self-report questionnaire with 15 specific questions were used. RESULTS: Among the 87 patients included in the analysis whose median age was 71 years, 57.5% used a 2-piece system, 69% used leg or thigh pockets, 74.7% were self-sufficient in emptying their stoma pockets. Autonomy on cutaneous support change was 38%. 62.1% of patients reported a peristomal skin event and 74.7% reported leaking stoma. In multivariate analysis, BMI>30, the presence of leaks and physical activity were significantly associated with the onset of peristomal skin events. CONCLUSION: This study sheds light on the practical modalities of management of urinary stoma and the occurrence of skin complications related to stoma in terms of frequency and predisposing factors. The results obtained are likely to guide practitioners in the information of future operations and in the management of complications of urinary stoma. LEVEL OF EVIDENCE: III.

Ureteroenteric strictures: a single center experience comparing Bricker versus Wallace ureteroileal anastomosis in patients after urinary diversion for bladder cancer.

BACKGROUND: To evaluate the outcome and complication rate in a single institution experience using the two most commonly used techniques of ureteroenteric anastomosis, the Bricker and Wallace anastomosis. METHODS: A total of 137 patients underwent ileal conduit for bladder cancer. Ureters were anastomosed by two experienced surgeons, one performing a Bricker and the other, a Wallace anastomosis. Stricture was identified during clinical follow-up. RESULTS: Seventy-five patients underwent a Bricker anastomotic, and 65 received a Wallace anastomosis. The average age was 70 in both groups, males were predominant (66% Bricker, 70% Wallace). Follow up period was 36.5 months in Bricker group and 17 months in Wallace group. In both groups, the body mass index (BMI) was similar (26.1 kg/m2 Bricker and 26.4 kg/m2 Wallace). We observed that the stricture rate after performing the Bricker anastomosis technique was 25.3% (19/75) as compared to 7.7% (5/65) after Wallace anastomosis technique, which was statistically significant (p = 0.001). In the Bricker group, patients with strictures had higher BMI (28.3 vs. 25.7 kg/m2, p = 0.05). On average it took 8.5 months in the Bricker group and three months in the Wallace group (p = 0.6) to develop stricture. CONCLUSIONS: The stricture rate was significantly higher when Bricker technique was applied. Although the BMI was not different in both groups, patients with a higher BMI were more likely to develop stricture. We believe that the approach of the separate and refluxing technique of Bricker anastomosis especially in obese patients poses a higher risk for anastomotic stricture formation.

Ileal conduit vs orthotopic neobladder: Which one offers the best health-related quality of life in patients undergoing radical cystectomy? A systematic review of literature and meta-analysis.

INTRODUCTION: Orthotopic neobladder (ONB) and ileal conduit (IC) are the most commonly practiced techniques of urinary diversion (UD) after radical cystectomy (RC) in bladder cancer patients. Data in the literature is still discordant regarding which UD technique offers the best HR-QoL. OBJECTIVE: The objective was to compare HR-QoL in patients undergoing ONB and IC after RC, through a systematic review of the literature and meta-analysis. MATERIAL AND METHODS: We performed a literature search of PubMed, ScienceDirect, CochraneLibrary and ClinicalTrials.Gov in September 2017 according to the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The studies were evaluated according to the "Oxford Center for Evidence-Based Medicine" criteria. The outcome measures evaluated were subdomains' scores of Bladder Cancer Index BCI: urinary function (UF), urinary bother (UB), bowel function (BF), bowel bother (BB), sexual function (SF) and sexual bother (SB). Continuous outcomes were compared using weighted means differences, with 95% confidence intervals. The presence of publication bias was examined by funnel plots. RESULTS: Four studies met the inclusion criteria. The pooled results demonstrated better UF and UB scores in IC patients: differences were -18.17 (95% CI: -27.49, -8.84, P=0.0001) and -3.72 (95% CI: -6.66, -0.79, P=0.01) respectively. There was no significant difference between IC and ONB patients in terms of BF and BB. SF was significantly better in ONB patients: the difference was 12.7 (95% CI, 6.32, 19.08, P<0.0001). However no significant difference was observed regarding SB. CONCLUSION: This meta-analysis of non-randomized studies demonstrated a better HR-QoL in urinary outcomes in IC patients compared with ONB patients.

[Comparison Bricker's and Wallace's anastomoses in ileal conduit: Retrospective, multicenter study]. / Comparaison des anastomoses Bricker et Wallace dans les urétérostomies cutanées trans-iléales : étude rétrospective, multicentrique.

OBJECTIVES: To compare Bricker and Wallace anastomosis in ileal conduit and search other risk factors of hydronephrosis. METHODS: Retrospective study in two French Hospitals with two different surgical practices. Hydronephrosis are separated in two groups: complicated hydronephrosis requiring reoperation and no complicated hydronephrosis. RESULTS: One hundred and sixty patients were included in the study and 317 renal units were explored (141 in Bricker's group and 176 in Wallace's group). The rate of complicated and non-complicated hydronephrosis are respectively 9.9 and 20.6% in Bricker's group against 10.8 and 13.6% in Wallace's group, without significant difference (P=0.8 and 0.1). In the other risk factors, only body mass index over 25 kg/m(2) was found as significant for complicated hydronephrosis. The left side and preoperative hydronephrosis are only associated to a risk of no complicated hydronephrosis (P=0.006 and 0.026). CONCLUSION: We found no difference between the two most common types of ureteroenteric anastomotic techniques. However, a high body mass index increases the rate of reoperation for hydronephrosis. LEVEL OF EVIDENCE: 5.

The Wallstent: long-term follow-up of metal stent placement for the treatment of benign ureteroileal anastomotic strictures after Bricker urinary diversion.

OBJECTIVE: To evaluate the long-term follow-up (primary and secondary patency) of metal stent placement in benign ureteroileal anastomotic strictures after Bricker urinary diversion and to compare the failed treatment group with the group of successfully treated patients to search for predisposing factors of stent failure. PATIENTS AND METHODS: For patients treated since 1989 for benign ureteroileal strictures after Bricker urinary diversion with end-to-side anastomosis, we retrospectively collected data on clinical history, stent placement, auxiliary measures and patency rates from a prospectively kept database. RESULTS: In all, 49 patients (mean age 64 years) underwent 56 metal stent procedures. Placement of the stent was possible in all patients. Stent patency without auxiliary treatment remained adequate in 23 cases (primary patency of 41.1%, mean follow-up 37.7 months). A secondary treatment was successfully performed in 11 patients who had stent obstruction, mostly caused by hyperplastic reaction, encrustation, or migration of the stent. The secondary patency rate was 60.7% (mean follow-up 55.8 months), comparable with patency rates of 36-100% described in literature with mostly small patient groups and much shorter follow-up periods. CONCLUSION: To the best of our knowledge we report the largest series of metal stenting in benign ureteroileal anastomotic strictures with the longest follow-up. We show that placement of a metal stent can lead to a permanent de-obstruction in approximately six out of 10 patients with preservation of renal function.

Hybrid technique has lower stricture rates than Wallace and Bricker.

INTRODUCTION: A clear consensus has not yet been reached on the optimal ureteroenteric anastomosis technique for ileal conduit urinary diversion following radical cystectomy. This study aims to determine the incidence of strictures and their management associated with these anastomosis techniques. METHODS: We conducted a retrospective, single-center study of patients who underwent radical cystectomy and urinary diversion between March 2014 and August 2022. Patients were categorized based on the ureteroenteric anastomosis technique used: Wallace, Bricker, or Hybrid. Strictures were identified through antegrade pyelography following nephrostomy placement. RESULTS: A total of 141 patients were included in the study, with 60 patients in the Wallace group (42 %), 42 patients in the Bricker group (30 %), and 39 patients in the Hybrid group (28 %). The overall incidence of ureteroenteric strictures was 15 %, with 7 patients in the Wallace group, 11 patients in the Bricker group, and 3 patients in the Hybrid group experiencing strictures. There was no statistically significant difference in stricture rates between the Wallace and Bricker groups (11 % vs. 26 %, p = 0.09) or between the Wallace and Hybrid groups (11 % vs. 7 %, p = 0.73). However, a statistically significant difference was observed between the Bricker and Hybrid groups (26 % vs. 7 %, p = 0.03). The mean time to stricture development was 9.2 ± 3.3 months for the Wallace group, 9.5 ± 3.7 months for the Bricker group, and 12.6 ± 5 months for the Hybrid group (p = 0.407). CONCLUSION: The Hybrid ureteroenteric anastomosis technique exhibits a lower stricture rate compared to the Bricker and Wallace techniques. It represents a safe and feasible alternative technique.

Robot-assisted intracorporeal ileal conduit urinary diversion: A two-center comparative study of Bricker versus Wallace ureteroileal anastomosis.

INTRODUCTION: This study was performed to evaluate the differences in the perioperative results, renal function, and incidence of hydronephrosis over time between the use of Bricker anastomosis and Wallace anastomosis for robot-assisted intracorporeal ileal conduit urinary diversion (RICIC). METHODS: Fifty-five patients who underwent RICIC at two institutions were evaluated (Bricker, n = 23; Wallace, n = 32). We investigated changes in estimated glomerular filtration rate and hydronephrosis before surgery and at 3, 6, and 12 months after surgery. RESULTS: The patients in the Bricker group were significantly older than those in the Wallace group. The urinary diversion time was significantly longer in the Bricker group. No significant difference in postoperative renal function was observed. Additionally, no significant difference was observed in the incidence of postoperative hydronephrosis. However, the incidence of right hydronephrosis tended to be high overall, especially in the Wallace group. No patients in either group required repair surgery or ureteral stent placement. CONCLUSIONS: In patients undergoing RICIC, there was no difference in postoperative renal function or the incidence of hydronephrosis between Wallace and Bricker anastomosis. Symptomatic hydronephrosis was not observed in either group. The present study showed that each method was equally effective and safe.

Late-onset enteric fistula following radical cystectomy for bladder cancer: A case report.

Enteric fistula is a rare early onset complication following radical cystectomy with urinary diversion for bladder cancer. We present the case of a 55-year-old woman presenting with an insidious fistula between the ileum and the ileal conduit, diagnosed 20-months after the initial surgery. A single surgical intervention was sufficient for treating this rare etiology. We herein present the case and discuss the available literature on the diagnosis and treatment of such complication.

Comparation between the Bricker ileal conduit vs double-barrelled wet colostomy after pelvic exenteration for gynaecological malignancies.

BACKGROUND: After exhausting other therapeutic options, pelvic exenteration is performed in patients who suffer from relapsed gynaecologic tumours, with most of them requiring some sort of urinary diversion. MATERIAL AND METHODS: The main objective of this study was to assess the short- and medium/long-term urinary complications associated with the Bricker ileal conduit versus double-barrelled wet colostomy after performing a pelvic exenteration for gynaecologic malignancies. RESULTS: A total of 61 pelvic exenterations were identified between November 2010 and April 2022; 29 Bricker ileal conduits and 20 double-barrelled wet colostomies were included in the urinary diversion analysis. Regarding the specific short-term urinary complications, no differences were found in the rate of urinary leakage (3 vs 0 %; p = 1), urostomy complications (7 vs 0 %; p = 0.51), acute renal failure (10 vs 20 %; p = 0.24) or urinary infection (0 vs 5 %; p = 0.41). Up to 69 % of patients with Bricker ileal conduits and 65 % of double-barrelled wet colostomies (p = 0.76) presented specific medium/long-term urinary complications. No differences in the rates of pyelonephritis (59 vs 53 %; p = 0.71), urinary fistula (0 vs 12 %; p = 0.13), ureteral stricture (10 vs 6 %; p = 1), conduit failure and reconstruction (7 vs 0 %; p = 0.53), renal failure (38 vs 29 %; p = 0.56) or electrolyte disorders (24 vs 18 %; p = 0.72) were found. CONCLUSIONS: There are no significant differences in the rate of complications between double-barrelled wet colostomy and the Bricker ileal conduit. The long-term complications related to urinary diversion remained high regardless of the type of technique. In this context, the double-barrelled wet colostomy presents advantages such as the single stoma placement and the simplicity of the technique.

Outcomes of Uretero-ileal Anastomosis in Bladder Cancer Cystectomies: Bricker vs. Wallace 1.

Background The two commonly used methods for uretero-ileal anastomosis (UIA) during radical cystectomy for muscle-invasive bladder cancer (MIBC) are the Bricker and Wallace 1 techniques. Published data on the incidence of strictures at anastomotic sites is limited. This study compares both anastomotic techniques in terms of uretero-ileal stricture (UIS) rates and the factors that govern it in the patient group. Material and methods Records of all patients presenting with bladder cancer who underwent radical cystectomy at the department of uro-oncology, Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC) Lahore, Pakistan, from January 1, 2009, to December 31, 2018, were reviewed retrospectively, and all adult patients aged >18 years out of them were selected for the study. Results With a total of 116 patients, the mean age was 54.37 ± 11.16 and a male majority (83.6%). Urinary diversion using ileal conduit was performed in 70 (60.3%) patients and the rest of them i.e. 46 (39.7%) had neobladder formation. Amongst them, uretero-ileal anastomosis was constructed via Bricker and Wallace 1 in 73 (62.9%) patients and 43 (37.1%) patients respectively. Pelvic radiotherapy was received by 13 (11.2%) patients. Anastomotic stricture developed in 19 (16.4%) cases. A relatively similar proportion of stricture rate was found in Bricker and Wallace 1 technique (10% vs 13%). Body mass index (BMI) was found to be significantly higher in patients who developed UIS. Incidence of stricture formation was more on the left than right side i.e. 12 (63.2%) vs five (26.3%) while two (10.5%) patients developed bilateral strictures. Conclusion No significant difference in stricture formation was noted between Bricker and Wallace 1 technique. High BMI and anastomotic leaks were the contributory factors for this complication during our experience.

Conservative treatment of urinary fistula: Case report.

Radical cystectomy is the gold standard treatment for muscular invasive bladder cancer. Bricker surgery is the most common technique used for urinary diversion; however, troublesome complications such as postoperative anastomotic stenosis or fistula may occur. The case of a patient who had a urinary fistula after Bricker surgery performed at our hospital, is described. The patient was successfully treated with continuous double-cannula negative-pressure drainage and avoided a second surgery. The patient recovered well and is on regular follow-up. This case highlights the importance of timely and relevant treatment for patients with postoperative urinary fistula to avoid more invasive surgery.

[Parastomal hernia in Bricker urinary diversion as a reversible cause of obstructive uropathy: An exceptional complication.] / Hernia paraestomal en derivación urinaria tipo Bricker como causa reversible de uropatía obstructiva: una complicación excepcional.

OBJECTIVE: Parastomal hernia in patientswith ileal urinary diversion is insufficiently described in theliterature, and among its complications, the presence ofurinary obstruction is not usually reported. METHODS: We present a 74-year-old male with a Brickertype urinary diversion. He presented urinary infections withCT scan showing hydronephrosis with obstruction of theileal conduit probably related to a parastomal hernia. Thehernia growth runs in parallel to the ureterohydronephrosis,so we performed a hernioplasty to solve the obstruction. CTat 6 months shows no urinary obstruction and no hernia recurrence.No hydronephrosis in the follow-up at 14 months. RESULTS: We reviewed the literature and we only foundthree articles that related parastomal hernia in Bricker toureterohydronephrosis, although none of them proved thisrelationship with the correction of the urinary obstructionafter hernia surgery. CONCLUSIONS: Parastomal hernia should be consideredin the differential diagnosis of obstructive uropathy in patientswith ileal urinary diversion.
