What ' s known on the subject? and What does the study add?Radical cystectomy remains associated with comparatively high perioperative morbidity and mortality, despite improvements in surgical techniques and perioperative care. At present, most studies on the complications associated with open radical cystectomy were derived from Western academic high-volume centres, and data from Japan and other Asian countries were very limited.Using the modifi ed Clavien grading system and 11 category grouping reported from MSKCC, we observed that 68% of patients experienced at least one complication within 90 days of surgery, and 17% of patients experienced major complications (90-day mortality rate = 2%), which were compatible with reports from Western high-volume centres. As far as we know, our report is the largest one regarding perioperative morbidity and mortality in Asian patients who underwent radical cystectomy. OBJECTIVE• To determine the type, incidence and severity of 90-day morbidity after radical cystectomy in our institution and our affi liated hospitals in accordance with a standard reporting methodology. A t present, most studies on complications associated with open radical cystectomy are derived from W estern academic high-volume centres and data from J apan and other A sian countries remain very limited. PATIENTS AND METHODS• The study comprised a retrospective multi-institutional study.• The records were reviewed of 928 patients who underwent open radical cystectomy between 1997 and 2010.• All complications within 90 days of surgery were categorized into 11 specifi c categories and graded in accordance with the modifi ed C lavien system.• Multivariate regression models were used to determine predictors of complications. RESULTS• A t least one complication was observed in 635 (68%) patients and a major (grade 3-5) complication was observed in 156 (17%) patients.• The most common complication categories were infectious (30%), gastrointestinal (26%), wound-related (21%) and genitourinary (15%).• The 30-day mortality rate was 0.8% and the 90-day mortality rate was 2%.• A multivariate regression model showed that previous cardiovascular comorbidity and type of urinary diversion (i.e. ileal conduit or neobladder) were signifi cant factors for any and major complications. CONCLUSIONS• Surgical complication-related radical cystectomy is signifi cant and both previous cardiovascular comorbidity and the type of urinary diversion were found to be signifi cant factors for any and major complications.• The 90-day mortality rate was 2%, which is compatible with reports from Western high-volume centres.
We report a case of spontaneous rupture of the urinary bladder (SRUB) due to bacterial cystitis in a 76-year-old woman with chief complaint of abdominal pain a day before presentation. She had fever (38.0°C), and her systolic blood pressure dropped to 70 mmHg; she was referred to our hospital, where she was admitted with a diagnosis of ileus. However, her abdominal pain worsened the following day, and abdominal CT showed free air. Emergency laparotomy was performed for suspicion of digestive tract perforation, which revealed a small hole at the dome of the urinary bladder and another at the peritoneum. Suture repair was performed. We reviewed the abdominal CT on admission and noted that the perforation of the urinary bladder was present during admission, whereas that of the peritoneum occurred the following day. SRUB is rare, and bacterial cystitis rarely causes it; thus, accurate diagnosis and proper treatment are essential.
Objective To determine the impact of postoperative complications on long-term survival outcomes in patients with bladder cancer undergoing radical cystectomy. Methods This retrospective multi-institutional study included 766 bladder cancer patients who underwent radical cystectomy between 2011 and 2017. Patient characteristics, perioperative outcomes, all complications within 90 days after surgery and survival outcomes were collected. Each complication was graded based on the Clavien-Dindo system, and grouped using a standardized grouping method. The Comprehensive Complication Index, which incorporates all complications into a single formula weighted by their severity, was utilized. Overall survival and recurrence-free survival (local, distant or urothelial recurrences) were stratified by Comprehensive Complication Index (high: ≥26.2; low: <26.2). A multivariate model was utilized to identify independent prognostic factors. Results The incidence of any and major complications (≥Clavien-Dindo grade III) was 70 and 24%, respectively. In terms of Comprehensive Complication Index, 34% (261/766) of the patients had ≥26.2. Patients with Comprehensive Complication Index ≥ 26.2 had shorter overall survival (4-year, 59.5 vs. 69.8%, respectively, log-rank test, P = 0.0037) and recurrence free survival (51.9 vs. 60.1%, respectively, P = 0.0234), than those with Comprehensive Complication Index < 26.2. The Cox multivariate model identified the age, performance status, pT-stage, pN-stage and higher CCI (overall survival: HR = 1.35, P = 0.0174, recurrence-free survival: HR = 1.26, P = 0.0443) as independent predictors of both overall survivial and recurrence-free survival. Conclusions Postoperative complications assessed by Comprehensive Complication Index had adverse effects on long-term survival outcomes. Physicians should be aware that major postoperative complications can adversely affect long-term disease control.
