Short- and long-term impact of the TaTME learning process: a single institutional study.

Background: Transanal total mesorectal excision (TaTME) is a promising and innovative approach for lower rectal cancer but requires high technical skill and learning process that can affect patient outcomes. We aimed to determine the learning curve of TaTME and then to assess its impact on 5-year oncologic outcomes.

Methods: Over a 54-month period, 94 patients underwent TaTME by experienced laparoscopic colorectal surgeons at our department.

Impact of an Enhanced Recovery After Surgery (ERAS) program on the management of complications after laparoscopic or robotic colectomy for cancer.

Purpose: Enhanced Recovery After Surgery (ERAS) reduces postoperative complications (POCs) after colorectal surgery; however, its impact on the management of POCs remains unclear. This study compared the diagnosis and management of POCs before and after implementing our ERAS protocol after laparoscopic or robotic colectomy for cancer and examined the short- and mid-term oncologic impacts.

Methods: This single-center, retrospective study evaluated all consecutive patients who underwent laparoscopic or robotic colectomy for cancer between 2012 and 2021, focusing on the incidence of POCs within 90 days.

A novel methodology to describe neuronal networks activity reveals spatiotemporal recruitment dynamics of synchronous bursting states.

We propose a novel phase based analysis with the purpose of quantifying the periodic bursts of activity observed in various neuronal systems. The way bursts are intiated and propagate in a spatial network is still insufficiently characterized. In particular, we investigate here how these spatiotemporal dynamics depend on the mean connection length.

Major hepatectomy decreased tumor growth in an experimental model of bilobar liver metastasis.

Background/purpose: Two-stage hepatectomy (TSH), is associated with a risk of drop-out due to tumoral progression following portal vein occlusion (PVO). We explored the impact of majorhepatectomy on tumor growth by objective radiological measures comparing to PVO and minor hepatectomy, using a model of bilobar colorectal liver metastasis (CLM).

Methods: CLM were induced in 48 BDIX rats by injection of DHDK12-cells.

Reconstruction after ureteral resection during HIPEC surgery: Re-implantation with uretero-neocystostomy seems safer than end-to-end anastomosis.

Introduction: Resection of the pelvic ureter may be necessary in cytoreductive surgery for peritoneal carcinomatosis in combination with hyperthermic intraperitoneal chemotherapy (HIPEC). As the morbidity for cytoreductive surgery with HIPEC has decreased, expert teams have begun to perform increasingly complex surgical procedures associated with HIPEC, including pelvic reconstructions. After ureteral resection, two types of reconstruction are possible: uretero-ureteral end-to-end anastomosis and uretero-vesical re-implantation or uretero-neocystostomy (the so-called psoas hitch technique).
