Pelvic exenteration for primary and recurrent malignancies in urology department / 中华泌尿外科杂志

Objective The objectives of present study is to investigate the safety and efficacy of pelvic exenteration (PE) for the treatment of pelvic malignancies in urology department.Methods From April 2010 to December 2014,20 patients with primary or recurrent pelvic malignancy accepted anterior pelvic exenteration (APE) or total pelvic exenteration (TPE) surgery,including 7 males and 13 females,ranged from 35 to 87 years old with an average of 65 years old.Ten case accepted APE and 10 for TPE.The ilium conduit was done in 5 cases for APE and 6 cases for TPE as urinary diversion,cutaneous ureterostomy was done in 5 cases for APE and 4 cases for TPE as urinary diversion.There were 6 cases primary tumor in APE group and 3 primary tumors in TPE.All of the patients had 13 cases of the urinary tract tumor group,and none of the urinary tract tumor group in 7 cases.There were 4 cases received preoperative chemotherapy in the urinary tract tumor group.No case received preoperative radiotherapy.3 cases received preoperative chemotherapy in none of the urinary tract tumor group,3 cased received preoperative radiotherapy.After induction of general anesthesia using a laryngeal mask for airway management.All patients took the abdominal incision,then dissected lymph nodes on both sides of the iliac vessels,freed bilateral ureters to the end of the swollen bladder,separated the peritoneal space.The bilateral vas deferens was cutted and ligated,then isolated and ligated the seminal vesicles between the posterior wall of the bladder and the anterior wall of the rectum.Lateral ligaments of bladder was cuted,then cuted ligament of prostate and puboprostatic ligament,sutured and cut deep vein of penis.Urethra of apex prostate was freed and cuted.Female patients needed to free the uterus and the posterior wall,cut the cardinal ligament and round ligament of uterus,isolate the posterior wall of the uterus to the posterior vaginal wall.Rectal resection adopted Miles operation.And sigmoid colostomy was performed on the left side of the abdominal wall.The perioperative characters,pathological results and patients' survival data were collected and analyzed.Results The average operation time for APE was 3.8 hours and 5.2 hours for TPE (P =0.173).Median length of hospital stay was 17.9 (7-47) days.The median blood loss was 300ml (80-2 500 ml) for APE and 400ml (50-6 000 ml) for TPE (P =0.909).The median follow-up time was 12.5 months (1-41months).The estimated 2-year survival rate for APE was 55.6％ and 45.0％ for TPE (P =0.642).Urinary system tumors group and non urinary system tumors group were analyzed and compared,The median survival time was 28 months and 13 months (P =0.538) in the two groups.The incidence of gastrointestinal complications of urinary system tumors and non-urinary system tumors was 7.7％ and 28.6％,incision complications was 7.7％ and 28.6％.Complications of urinary diversion only occurred in the non urologic tumor group,the incidence was 14.3％.The incidence of transfusion in two groups was 46.2％ and 28.6％.Conclusions Pelvic exenteration (APE and TPE) could be a safe and reliable choice for local advanced primary and recurrent pelvic malignancy.Even for the recurrent malignancies,the survival results of the patients were satisfactory.

Exenteración pélvica total por cáncer primario del recto: resultados inmediatos y alejados / Total pelvic exenteration for locally advanced rectal tumors: experience in 10 patients

Objetivo: El objetivo de este estudio es mostrar los resultados inmediatos y alejados de la exenteración pélvica total (EPT) en el manejo de tumores primarios de recto localmente avanzados. Se describe una alternativa técnica en los casos de EPT supraelevador. La EPT puede ser la única oportunidad de curación en pacientes con tumores pélvicos de gran volumen. Material y método: Se incluyen tumores T4 por la estadificación clínica o los hallazgos operatorios sometidos a una EPT con intención curativa. Resultados: En un periodo de 16 años se intervienen con esta técnica 10 pacientes, 6 de los cuales recibieron radioquimioterapia neoadyuvante. La técnica clásica se empleó en 3 pacientes y la EPT supraelevador, en 6. El promedio de hospitalización fue de 36 días (rango, 18-97) y la morbilidad alcanzó el 80%. El estudio de la pieza operatoria confirmó un tumor T4 en 6 pacientes, T3 en 3 y T0 en uno. Los 6 pacientes con neoadyuvancia son 1 ypT0N0M0, 2 ypIIA, 2 ypIIC y 1 ypIIIB. El resto eran 2 pIIC y 2 pIIIC. En el seguimiento hay 5 pacientes vivos entre 30 y 180 meses, y 3 fallecen por metástasis a distancia sin recidiva local. Conclusión: La EPT es una intervención asociada a una elevada morbilidad y larga estadía hospitalaria. La EPT supraelevador protegida mediante una ileostomía transitoria evitó una colostomía definitiva en 6 de 10 casos. La ileostomía urinaria muestra resultados funcionales satisfactorios en el largo plazo. La sobrevida prolongada en la mitad de los pacientes justifica la indicación de la técnica en casos seleccionados.

Aim: To report the results of total pelvic exenteration (TPE) in patients with locally advanced primary rectal tumors. Material and method: We report 10 patients with stage 4 rectal tumors subjected to a potentially curative TPE in a period of 16 years. Results: Six patients received also adjuvant chemoradiotherapy. A classic technique was used in 3 patients and a supra-elevator technique in 6. Mean hospitalization length was 36 days, and 80% of patients had complications. The pathological study of the surgical piece confirmed a T4 tumor in 6 patients, T3 in 3 and T0 in one. Among patients who received chemoradiotherapy, one was in stage ypT0N0M0, 2 in ypIIA, 2 in ypIIC, one in ypIIIB, 2 in pIIC and 2 in pIIIC. During follow up 3 patients survived between 30 and 180 months and three died due to distant metastases without local relapse. Conclusion: TPE requires long hospital stays and has a high rate of complications. Supra-elevator TPE protected with a transitory ileostomy avoided definitive colostomy in 6 of 10 cases. Urinary ileostomy had satisfactory long term functional results. The prolonged survival of half of the patients justifies the use of this surgical technique.

A Case of Total Pelvic Exenteration for Recurrent Cervical Carcinoma Found after Simple Hysterectomy / 대한산부인과학회잡지

Pelvic exenteration is a salvage procedure performed for centrally recurrent gynecologic cancers. The procedure involve en bloc resection to a greater or lesser degree of all pelvic structures, including the uterus, cervix, vagina, bladder and rectum. It was first reported by Brunschwig in 1948 as an ultra-radical surgical treatment for advanced and recurrent cervical cancer. Most patients who are candidates for the procedure have a diagnosis of recurrent cervical cancer that previously has been treated with surgery and radiation or radiation alone. In some cases, patients with recurrent uterine, vulvar, or vaginal cancers may benefit from pelvic exenteration. Currently, operative mortality rates range from 3% to 5%, the rate of major perioperative complications is 30-22% and the overall 5-year survival rate is those patients who successfully undergo the procedure ranges from 20-50%. We experience a case of total pelvic exenteration for recurrent cervical carcinoma found after simple hysterectomy. It is presented with a brief reviews of literatures.
