Hand-assisted laparoscopic versus laparoscopic nephrectomy as outpatient procedures: a prospective randomized study

Safety and oncological outcomes for large (stage ≥T2b) and locally advanced renal cell carcinoma: comparison between laparoscopic and modified hand-assisted laparoscopic radical nephrectomy

Objective

To compare the operative and oncologic outcomes between hand-assisted laparoscopic radical nephrectomy (HALRN) and laparoscopic radical nephrectomy (LRN) for large (stage ≥T2b) and locally advanced renal cell carcinoma.

Methods

We retrospectively collected data from patients who underwent HALRN or LRN for stage ≥T2b renal cell carcinoma from January 2011 to January 2018 in our institution. The patients’ demographics, perioperative parameters, and postoperative follow-up data were compared between the two groups. The survival outcome was estimated using the Kaplan–Meier method.

Results

The HALRN group comprised 78 patients, and the LRN group comprised 63 patients. The median operative duration was significantly shorter in the HALRN than LRN group. The two groups were equivalent in terms of the incision length, blood loss, complication rate, and duration of hospitalization. In the HALRN and LRN groups, the 5-year overall survival rates were 69.4% and 73.1%, the 5-year cancer-specific survival rates were 80.0% and 83.3%, and the 5-year progression-free survival rates were 66.4% and 74.7%, respectively, with no significant differences.

Conclusions

Compared with LRN, HALRN may offer a shorter operative duration and equivalent surgical outcomes without sacrificing oncological efficacy. In addition, HALRN has specific advantages for extremely large and complicated renal tumors.

Novel technique: direct access partial nephrectomy approach through a transperitoneal working space (Roskilde technique)

Objectives: To describe a direct access partial nephrectomy technique through a transperitoneal working space (Roskilde technique).Materials and methods: Prospective single-center descriptive study between April 2015 and January 2017. The surgical outcomes are evaluated according to the Trifecta criteria (negative margins, warm ischemia time < 20 min and a Clavien-Dindo complication score < 3).Surgical procedure: The same access to the transperitoneal cavity as in a Standard transperitoneal Partial Nephrectomy was used. A direct access was established by incision of the peritoneum directly onto the renal fascia. The renal vessels and tumor were identified and the tumor removed with standard technique. The perinephric fat and peritoneum were then closed with a running suture.Results: In total, 122 patients underwent the Roskilde technique. The mean age was 62.2 years, the median Padua score was 12 (IQR = 9-12) and the median tumor size was 32 mm (IQR = 12-90). The median operative time was 101 min (IQR = 90-125). The trifecta achievement criteria goal was achieved in 116/122 (95%), with a median warm ischemia time of 8 min (IQR = 0-12).Conclusions: The Roskilde technique is safe and feasible. It can be performed on complex renal masses, and it seems to result in short operative times and high Trifecta achievement.Trial registration: None.
