ABSTRACT Purpose: To introduce our experience with intracorporeal ileal conduit and evaluate the safety and feasibility of this endoscopic urinary diversion. Materials and Methods: Between March 2014 and July 2017, thirty-six consecutive patients underwent laparoscopic radical cystectomy with intracorporeal ileal conduit. Patients’ demographic data, perioperative data, 90-days postoperative outcomes and complications were collected. This cohort were divided into two groups of 18 patients each by chronological order of the operations to facilitate comparison of clinical data. Data were evaluated using the students’ T test, Mann-Whitney test and Fisher's Exact test. Results: All surgeries were completed successfully with no conversion. Median total operating time and median intracorporeal urinary diversion time were 304 and 105 minutes, respectively. Median estimated blood loss was 200 mL, and median lymph node yield was 21. Twenty-six Clavien grade < 3 complications occurred within 30-days and 9 occurred within 30-90 days. Five Clavien grade 3-5 complications occurred within 30 days. No statistically significant differences were found between the two groups except for intracorporeal urinary diversion time. At median follow-up of 17.5 (range 3-42) months, 6 patients experienced tumor recurrence/metastasis and 4 of these patients died. Conclusions: Intracorporeal ileal conduit following laparoscopic radical cystectomy is safe, feasible and reproducible. With the accumulation of experience, the operation time can be controlled at a satisfactory level.

ABSTRACT Purpose: To describe our technique and outcomes for laparoscopic intracorporeal ileal neobladder (ICNB) reconstruction. Materials and Methods: From April 2014 to November 2016, 21 patients underwent laparoscopic ICNB at our tertiary referral centre. ICNB with bilateral isoperistaltic afferent limbs and several technique improvements were introduced. Demographics, clinical, and pathological data were collected. Perioperative, 1-year oncologic, 1-year Quality of life and 1-year functional outcomes were reported. Results: ICNB was successfully performed in all 21 patients without open conversion and transfusion. Mean operative time was 345.6±66.9 min, including 106±22 min for LRC and PLND and 204±46.4 min for ICNB, respectively. Mean established blood loss was 192±146 mL. The overall incidence of 90-d complication was 33.3%, while major complication occurred in 4.8%. One-year daytime and night-time continence rates were 85.7% and 57.1%, respectively. One patient died from myocardial infarction six months postoperatively, and two patients had lung metastasis five months and six months respectively. Conclusions: We described our experience of 3D LRC with a novel intracorporeal orthotopic ileal neobladder, and the technique improvements facilitate the procedure. However, further studies are required to evaluate long-term outcomes of the intracorporeal neobladder with bilateral isoperistaltic afferent limbs.
