Perioperative mortality for radical cystectomy in the modern Era: experience from a tertiary referral center

ABSTRACT Purpose To evaluate the perioperative mortality and contributing variables among patients who underwent radical cystectomy (RC) for bladder cancer in recent decades, with comparison between modern (after 2010) and premodern (before 2010) eras. Materials and Methods Using our institutional review board-approved database, we reviewed the records of patients who underwent RC for primary urothelial bladder carcinoma with curative intent from January 2003 to December 2019. The primary and secondary outcomes were 90- and 30-day mortality. Univariate and multivariable logistic regression models were applied to assess the impact of perioperative variables on 90-day mortality. Results A total of 2047 patients with a mean±SD age of 69.6±10.6 years were included. The 30- and 90-day mortality rates were 1.3% and 4.9%, respectively, and consistent during the past two decades. Among 100 deaths within 90 days, 18 occurred during index hospitalization. Infectious, pulmonary, and cardiac complications were the leading mortality causes. Multivariable analysis showed that age (Odds Ratio: OR 1.05), Charlson comorbidity index ≥ 2 (OR 1.82), blood transfusion (OR 1.95), and pathological node disease (OR 2.85) were independently associated with 90-day mortality. Nevertheless, the surgical approach and enhanced recovery protocols had no significant effect on 90-day mortality. Conclusion The 90-day mortality for RC is approaching five percent, with infectious, pulmonary, and cardiac complications as the leading mortality causes. Older age, higher comorbidity, blood transfusion, and pathological lymph node involvement are independently associated with 90-day mortality.

NOTES hybrid transvaginal radical nephrectomy for tumor: stepwise progression toward a first successful clinical case.

BACKGROUND: Natural orifice translumenal endoscopic surgery (NOTES) has been used to perform nephrectomy in the laboratory; however, clinical reports to date have used multiple abdominal trocars to assist the transvaginal procedure. OBJECTIVE: To present our stepwise technique development and the first successful clinical case of NOTES transvaginal radical nephrectomy for tumor with umbilical assistance without extraumbilical skin incisions. DESIGN, SETTING, AND PARTICIPANTS: The four transvaginal NOTES procedures were performed at two institutions after obtaining institutional review board approval. Various operative steps were developed experimentally in three clinical cases, and on March 7, 2009, we performed the first successful case of NOTES hybrid transvaginal radical nephrectomy without any extraumbilical skin incisions. Using one multichannel access port in the vagina and one in the umbilicus, laparoscopic visualization, intraoperative tissue dissection, and hilar control were performed transvaginally and transumbilically. The intact specimen was extracted transvaginally. MEASUREMENTS: All perioperative data were accrued prospectively. A stepwise progression to the successful completion of the fourth case is systematically presented. RESULTS AND LIMITATIONS: Intraoperatively, at incrementally more advanced stages of the procedure, the first three NOTES clinical cases were electively converted to standard laparoscopy because of rectal injury during vaginal entry, of failure to progress, and of gradual bleeding during upper-pole dissection after transvaginal hilar control, respectively. The fourth case was successfully completed via transvaginal and umbilical access without conversion to standard laparoscopy. Operative time was 3.7 h, estimated blood loss was 150 cm(3), and hospital stay was 1 d. Final pathology confirmed a 220-g, pT1b, 7-cm, grade 2, clear-cell renal cell carcinoma with negative margins. The patient was readmitted for an intraabdominal collection that responded to drainage and antibiotics. CONCLUSIONS: We report our stepwise progression and the initial successful clinical case of NOTES hybrid transvaginal radical nephrectomy for tumor, assisted with only one umbilical trocar. Although transvaginal nephrectomy is feasible in the highly selected patient with favorable intraoperative circumstances, considerable refinements in technique and technology are necessary if this approach is to advance beyond mere anecdote.

Oncological outcomes of laparoscopic radical nephrectomy for renal cancer.

PURPOSE: To report the 5-year oncological outcomes of patients undergoing laparoscopic radical nephrectomy for renal cancer compared to a cohort of patients undergoing open radical nephrectomy. METHODS: We retrospectively analyzed the data of 88 patients undergoing radical nephrectomy for renal cell carcinoma prior to January 2000. Of these, 45 patients underwent laparoscopic radical nephrectomy, and 43 patients underwent open radical nephrectomy. Inclusion criteria comprised clinically organ-confined tumors of 15 cm or less in size without concomitant lymphadenopathy or vena cava thrombus. Oncological follow-up data were obtained from charts, radiological reports, and phone calls to patients or their families, and were calculated from the date of surgery to the date of last appointment with physician or date of death. RESULTS: All laparoscopic procedures were completed without open conversion. On comparing the laparoscopic radical nephrectomy and open radical nephrectomy groups, mean tumor size was 5. 8 vs 6.2 cm (P = . 44), mean blood loss was 183 vs 461 mL (P = . 004), and mean operative time was 2.8 vs 3.7 hrs (P < . 001). Over a mean follow-up of 5 years in the laparoscopic radical nephrectomy group and 6 years in the open radical nephrectomy group, the overall survival was 81% vs 79% (P = . 47), and cancer-specific survival was 90% vs 92% (P = . 70) , respectively. CONCLUSIONS: Laparoscopic radical nephrectomy for renal cancer confers equivalent 5-year oncological outcomes to those of open surgery.

OBJETIVO: Relatar os resultados oncológicos após 5 anos de seguimento em pacientes submetidos a nefrectomia radical laparoscópica para tratamento do câncer renal, comparando esses com os resultados obtidos com um grupo de pacientes submetidos a nefrectomia radical aberta. MÉTODOS: Foram analisadas retrospectivamente as informações obtidas de 88 pacientes submetidos a nefrectomia radical para o tratamento do carcinoma renal realizadas previamente a Janeiro de 2000. Destes pacientes, 45 foram tratados com nefrectomia radical laparoscópica e 43 com nefrectomia radical aberta. Foram incluídos pacientes com tumores localizados com tamanho máximo de 15 cm, sem adenopatia ou sinal de envolvimento de veia renal na avaliação radiologica pré-operatória. As informações sobre o seguimento dos pacientes foram obtidas a partir de prontuários, laudos de exames radiológicos e ligações telefônicas para pacientes e/ou familiares. O seguimento foi calculado desde a data da cirurgia até a última consulta médica ou data de falecimento. RESULTADOS: Todos os procedimentos laparoscópicos foram realizados sem conversão para a técnica aberta. O tamanho médio tumoral foi de 5.8 e. 6.2 cm (P=0.44), perda sanguínea estimada de 183 e. 461 mL (P=0.004), e tempo operatório de 2.8 e. 3.7 horas (P<0.001) , respectivamente para os grupos nefrectomia radical laparoscópica e nefrectomia radical aberta. O tempo de seguimento médio foi de 5 anos para o grupo nefrectomia radical laparoscópica e 6 anos para o grupo nefrectomia radical aberta. A sobrevida global após 5 anos foi de 81 por cento e 79 por cento (P=0.47), e a sobrevida específica para cancer foi de 90 por cento e 92 por cento (P=0.70), para os grupos nefrectomia radical laparoscópica e nefrectomia radical aberta respectivamente. CONCLUSÃO: A nefrectomia radical laparoscópica tem resultados oncológicos em 5 anos similares a técnica convencional aberta.
