OBJECTIVES: To compare King Saud University Medical City experience in laparoscopic liver resection with our previously established database for open resections. METHODS: A retrospective study was conducted at King Saud University Medical City, Riyadh, Saudi Arabia. All adult patients who underwent liver resection from 2006 to 2017 were included. Patients who had their procedure converted to open were excluded. RESULTS: Among the 111 liver resections included, 22 (19...

Purpose: Tumors continuously evolve to maintain growth; secondary mutations facilitate this process, resulting in high tumor heterogeneity. In this study, we compared mutations in paired primary and metastatic colorectal cancer tumor samples to determine whether tumor heterogeneity can predict tumor metastasis. Experimental Design: Somatic variations in 46 pairs of matched primary-liver metastatic tumors and 42 primary tumors without metastasis were analyzed by whole-exome sequencing. Tumor clonality was estimated from single-nucleotide and copy-number variations...

BACKGROUND: Hepatic resection is a major surgical procedure. Data on outcomes of hepatectomy in Saudi Arabia are scarce. OBJECTIVE: To measure morbidity and mortality and assess predictors of outcome after hepatectomy. DESIGN: Descriptive study. SETTING: Tertiary care center in Saudi Arabia with well established hepatobiliary surgery unit. PATIENTS AND METHODS: All patients undergoing liver resection in our institute during 2006-2014...

BACKGROUND/AIM: To elucidate colorectal cancer (CRC) disease patterns, demographics, characteristics, stage at presentation, metastases, and survival rates of patients, particularly those with liver metastases, at our center as the first report from the Kingdom of Saudi Arabia. PATIENTS AND METHODS: We performed a retrospective, single-center database study based on the histological diagnosis of CRC in patients seen at the King Khalid University Hospital between 2007 and 2011...

Surgical resection of colorectal liver metastases (CRLM) has a well-documented improvement in survival. To benefit from this intervention, proper selection of patients who would be adequate surgical candidates becomes vital. A combination of imaging techniques may be utilized in the detection of the lesions. The criteria for resection are continuously evolving; currently, the requirements that need be met to undergo resection of CRLM are: the anticipation of attaining a negative margin (R0 resection), whilst maintaining an adequate functioning future liver remnant...
