En bloc laparoscopic radical nephrectomy with inferior vena cava thrombectomy: A single‐institution experience

Abstract

Objective To report the outcomes of laparoscopic radical nephrectomy with inferior vena cava thrombectomy for right renal cell carcinoma at Kobe City Medical Center General Hospital, Kobe, Hyogo, Japan. Method A retrospective review of the clinical records of five patients who underwent laparoscopic radical nephrectomy with inferior vena cava thrombectomy for right renal cell carcinoma between 2013 and 2017 was carried out. The surgical procedure included ligation and cutting of the right renal artery, followed by kidney mobilization. The left renal vein, and the caudal and cephalad sides of the inferior vena cava thrombus were clamped using laparoscopic vascular clamps, and the inferior vena cava was incised. The free kidney and tumor thrombus were placed en bloc in a retrieval bag. Subsequently, the inferior vena cava was laparoscopically closed using a continuous suture. Results The median operative time, pneumoperitoneum time, blood loss and postoperative hospital stay were 316 min, 266 min, 400 mL and 7 days, respectively. The median clamp time was 28 min (range 13–105 min). One patient (20%) required a perioperative blood transfusion. The surgical margin was negative in all patients. Only one patient experienced a major complication (Clavien–Dindo grade ≥3), namely a postoperative hemorrhage requiring transarterial embolism. Conclusion En bloc laparoscopic radical nephrectomy with inferior vena cava thrombectomy is a challenging yet feasible procedure for experienced surgeons in carefully selected patients. Further studies of this surgical procedure are required for standardization and safe application.

Treatment of a duodenal-caval fistula secondary to peptic ulcer disease

“…Laparoscopic surgery of the vena cava has been performed for tumors involving the IVC, even for extensive tumors. 4 Additionally, laparoscopic IVC filter removal has been described. 5 Although, at present, no descriptions of laparoscopic management of duodenal-caval fistulas have been reported, it could provide a potential alternative approach in the care of these patients.…”

Modified vein clamping technique for renal cell carcinoma complicated with level I–II IVC thrombi: a study at a single centre

“…In addition, the vein wall might collapse, and the tumour thrombus might be seeded into the peritoneal cavity. Yoichiro T et al adopted a method of “en bloc” nephrectomy with IVC thrombectomy, where detaching the tumour thrombus is unnecessary [ 23 ]. However, that method also features two main disadvantages.…”

Cavotomía mínima invasiva para metastasectomía en recurrencia de carcinoma renal

“…En el 80% de los pacientes se utilizó un abordaje puramente laparoscópico mientras en el 20% se utilizó una técnica mano asistida. (9) El 60% de los pacientes presentó un trombo en vena cava nivel II, en el 20% un nivel III (quien obtuvo terapia blanco previa por 4 meses) y en el otro 20% un nivel I según clasificación de mayo, (6) presentando un tiempo quirúrgico de 316 minutos, ligadura de la VCI de 28 minutos promedio, sangrado de 400 ml (100-1560 ml) y solo un paciente requirió trasfusión de hemoderivados. Se concluyó que siempre que sea técnicamente posible, la cirugía debe ofrecerse como piedra angular, sin embargo, cuenta con complicaciones hasta en un 38% y un 4-10% de mortalidad, el porcenta-je de complicaciones aumenta con el nivel del trombo 8% nivel I, 20% nivel II, 26% nivel III y un 47% en nivel IV.…”
