Vascular liver segmentation: a narrative review on methods and new insights brought by artificial intelligence.

Liver vessel segmentation from routinely performed medical imaging is a useful tool for diagnosis, treatment planning and delivery, and prognosis evaluation for many diseases, particularly liver cancer. A precise representation of liver anatomy is crucial to define the extent of the disease and, when suitable, the consequent resective or ablative procedure, in order to guarantee a radical treatment without sacrificing an excessive volume of healthy liver. Once mainly performed manually, with notable cost in terms of time and human energies, vessel segmentation is currently realized through the application of artificial intelligence (AI), which has gained increased interest and development of the field.

Low-Impact Laparoscopy vs Conventional Laparoscopy for Appendectomy: A Prospective Randomized Trial.

Background: Low-impact laparoscopy (LIL), combining low-pressure insufflation and microlaparoscopy, is a surgical technique that is still not widely used and that has never been evaluated for the management of acute appendicitis. The aim of this study is to assess the feasibility of an LIL protocol, to compare postoperative pain, average length of stay, and in-hospital use of analgesics by patients who underwent appendectomy according to a conventional laparoscopy or an LIL protocol.

Study Design: Patients presenting with acute uncomplicated appendicitis who were operated on between January 1, 2021, and July 10, 2022, were included in this double-blind, single-center, prospective study.

Preoperative prognostic factors for obstructive colorectal cancer.

Aim: The aim of the study was to determine the preoperative predictive factors of overall survival, relapse-free survival, and peritoneal carcinomatosis in obstructive colorectal cancer.

Methods: Data from patients undergoing emergency surgery for obstructive colorectal cancer at our center between 2004 and 2016 were extracted retrospectively from our health records. Several preoperative parameters were used to predict survival and peritoneal carcinomatosis using univariate and multivariate analysis, and ROC curves.
