Robot-assisted radical cystectomy with intracorporeal reconstruction of urinary diversion by mechanical stapler: prospective evaluation of early and late complications

Improving safety in the performance of robotic urinary diversions: a narrative review

Urinary diversions are performed for a wide variety of indications, including bladder removal for cancer treatment, post-cancer treatment complications, trauma, or bladder pain. The robotic approach has been increasingly used in performing urinary diversions since the introduction of the surgical robot. A PubMed keyword search was performed on September 14, 2023 with the terms: robotic and urinary diversion. A narrative review of the literature was then conducted, with a focus on outcomes and complications following urinary diversion. Studies demonstrated that the robotic approach to cystectomy with urinary diversion was safe and productive, whether the diversion was performed intracorporeally or extracorporeally, and that outcomes are comparable to the open approach. Despite reports of successes and technique improvements, the complication rate following robotic cystectomy with urinary diversion is over 50%. Common complications associated with urinary diversion include bowel complications, ureteroenteric anastomotic strictures, urine leak, urinary tract infections, internal hernias, and parastomal hernias. Many strategies have been developed to improve the complication rate following robotic urinary diversion, including specialized training programs and enhanced recovery after surgery protocols. In conclusion, with the increasing adoption of the robotic approach for urinary diversions, it is important to continue to develop strategies to mitigate surgical risk. Future research should focus on further refinement of training and surgical approaches to prevent and treat complications following robotic urinary diversions.

Stapled W-shaped (Hautmann) Orthotopic Ileal Neobladder. Functional Results and Complications over a 13-year Period

BACKGROUND AND OBJECTIVE

The preferable technique for orthotopic bladder substitution after radical cystectomy is debated. The aim of this study was to describe our technique of a stapled W-shaped ileal neobladder and assess the complications and functional results in 100 patients. treated from December 2009 to July 2022.

METHODS

The W-shaped ileal neobladder is created with lateral arms of 15 cm and central arms of 10 cm. Following an incision of the lower part of the two medial arms, a 10-cm GIA titanium stapler is used to detubularize the medial arms first and then the laterals to the medial arms. Urethral-neobladder anastomosis and end-to-end ureteroileal anastomosis are finally carried out. We reported on clinical data, complications, and urinary function outcomes assessed by the International Consultation on Incontinence Questionnaire (ICIQ)-Short Form and daytime/24-h pad test. Full urinary continence (UC) was defined as pad tests yielding 0 g.

KEY FINDINGS AND LIMITATIONS

The median surgical time was 210 min. The early (up to 90 d) and late (>90 d) complication rates were 18% (2% grade ≥4) and 11.7% (2% grade ≥4), respectively. Two patients had "late" bladder stones due to chronic urinary retention, whereas none developed calcifications in the neobladder along the stapling lines. Daytime and 24-h UC rates were 74.7% and 72.4% at 12 mo, 82.7% and 72.4% at 36 mo, respectively. Median ICIQ scores were in line with pad test results, being 0 in patients with full UC.

CONCLUSIONS AND CLINICAL IMPLICATIONS

Our stapled W-shaped ileal neobladder technique was found to be simple and fast to shape, with a low complication rate, and yielded favorable long-term functional outcomes.

PATIENT SUMMARY

This study details the surgical technique, complications, and functional outcomes of patients who underwent open cystectomy with a stapled W-shaped ileal neobladder. Our results indicate that this approach is safe and provides favorable long-term functional outcomes.

Intracorporeal urinary diversion offers the advantage of delaying postoperative renal function injury in patients undergoing robot-assisted radical cystectomy

Objective

To analyze changes in renal function and associated risk factors in patients with bladder cancer undergoing robot-assisted radical cystectomy (RARC) with intracorporeal or extracorporeal urinary diversion (ICUD or ECUD).

Methods

Clinical-pathological data was extracted from electronic medical records of 266 patients with bladder cancer who underwent RARC at our institution between August 2015 and August 2022. Postoperative renal function was assessed using the estimated glomerular filtration rate (eGFR).

Result

Patients were classified into ECUD and ICUD groups based on the surgical approach. Significant differences in eGFR were observed between the two groups at 1, 2, and 3 years postoperatively. Moreover, 112 patients (42.1%) experienced long-term renal function injury. Independent risk factors for long-term renal function injury included the type of surgical approach, ureteroenteric anastomotic strictures, and pathological stage T3 or above. In terms of short-term renal function, 30 cases of acute kidney injury (AKI) were observed, with an incidence rate of 11.3%. No difference in AKI incidence was found between the groups.

Conclusions

Postoperative AKI and chronic kidney injury are prevalent complications following RC. This study highlights that pathological stage, ureteroenteric anastomotic strictures, and ECUD significantly impact long-term renal function, but the type of urinary diversion (ileal conduit or orthotopic neobladder) had no effect on renal function, and ICUD was superior in terms of long-term renal injury rate. Therefore, precise preoperative assessment and the selection of appropriate surgical approach are crucial for preserving renal function in patients with bladder cancer.

Effectiveness of bedside staplers in bariatric robotic procedures

BACKGROUND

Few studies have evaluated the use of laparoscopic staplers in robotic procedures (bedside stapling, BS). This study aims to evaluate the effectiveness of BS compared with robotic staplers (RS) in bariatric robotic procedures.

METHODS

Patients who underwent robotic sleeve gastrectomy or gastric bypass elective procedures between 1/1/2021 and 12/31/2021 were extracted from PINC AI™ Healthcare Data. The following clinical outcomes were compared: blood transfusion, bleeding, anastomotic leak, intensive care unit (ICU) visit, and 30-day readmission, operating room (OR) time, inpatient costs, and length of stay. We evaluated baseline balance in BS and RS and bivariate association between covariates and outcomes using Chi-square or Fisher exact test and t-test or ANOVA. Multivariable general linear mixed models (GLMMs) with respective gamma or binomial distribution and log-link function were used to obtain adjusted outcomes variations between BS and RS.

RESULTS

Total of 7268 discharges were included with 1603 (22.1%) BS and 5665 (77.9%) RS cases. RS cases consisted of a higher number of patients who were Hispanic (17.0% vs. 9.4%), had Medicaid (26.9% vs. 19.4%) and underwent sleeve gastrectomy (68.4% vs. 53.5%). Higher proportions of RS cases were done by providers in Northeast region (35.5% vs. 24.3%), smaller size (< 500 beds; 71.1% vs. 52.3%), and teaching hospitals (59.4% vs. 39%). The adjusted outcomes variations demonstrated that patients that had RS were significantly more likely to have blood transfusions, ICU stays, increased ORT (19 min) and costs ($1273). Sensitivity analysis showed similar results, except no significant differences in blood transfusion rates in both groups.

CONCLUSIONS

Bedside staplers significantly reduce healthcare resource utilization with equivalent effectiveness and fewer ICU stays compared to robotic staplers.

Arterio-ureteral fistula from a pseudoaneurysm of the right common iliac artery after robot-assisted laparoscopic radical cystectomy: A case report

Arterio-ureteral fistulas (AUFs), which are relatively rare but potentially life-threatening, require prompt diagnosis and treatment. We reported a case of AUFs following robot-assisted laparoscopic radical cystectomy (RARC) with extended pelvic lymph node dissection and ileal conduit urinary diversion for muscle-invasive bladder cancer, which resulted in massive hemorrhage. Urine leaked from the anastomosis between the ureter, and the end of the ileal conduit was infected, which resulted in an AUF between the pseudoaneurysm of the right common iliac artery and the ureter. The AUF was managed successfully by vascular intervention with an arterial stent graft.

Feasibility and safety of laparoscopic radical cystectomy for male octogenarians with muscle-invasive bladder cancer

This study was designed to evaluate the safety and feasibility of laparoscopic radical cystectomy (LRC) for male octogenarian patients with muscle-invasive bladder cancer (MIBC). Briefly, a total of 57 male octogenarian patients (A group) with bladder carcinoma were enrolled and underwent LRC and intracorporeal pelvic lymph node dissection with bilateral cutaneous ureterostomy from May 2016 to December 2022. Besides, 63 male patients (age < 80 years old) with bladder carcinoma undergoing LRC and 17 octogenarian male patients with bladder carcinoma undergoing open radical cystectomy (ORC) were enrolled in B and C groups as control. All perioperative clinical materials and outcomes of long-term follow-up, and complication were collected. The specific results were shown as follows. Compared with C group, the operation time and resected lymph node in A group was increased, and the estimated blood loss, the number of transfusion needed, duration of pelvic drainage and hospital stay after surgery was decreased. The death rate and ileus complication rate were higher in A group (12 cases) than in C group (15 cases). The cases of ureteral stricture in A group (13 cases) was decreased compared with that in C group. Overall, LRC and bilateral cutaneous ureterostomy are safe, feasible and better choices for the treatment of male octogenarian patients with MIBC. The octogenarian receiving cutaneous ureterostomy heals slowly and exists certain incomplete intestinal obstruction after surgery.
