“…At this early time‐point, body weight was reduced by an average of 1.9 kg, mainly due to drainage of water‐rich glycogen from liver and muscle, whereas large peripheral fat depots remained essentially intact . Liver volume was reduced by 10% , whilst BA synthesis, doubled in the obese group compared to controls, was reduced by 46% ( P = 0.024) and thus normalized (Fig. a).…”

“…To test this hypothesis, we analysed material from a study in which morbidly obese individuals were monitored for 4 weeks after switching to an LCD . The primary aim of that study was to evaluate the time required to reduce liver volume prior to laparoscopic gastric bypass surgery.…”

“…[8] Lewis et al 2006 [10] found liver volume reduced by 14% over a six week period following the implementation of a low calorie diet. Edholm et al 2014 [28] showed an average decrease in liver size of 18% in ten female participants following two weeks on a low calorie diet. Van Theil et al 1987 [29] evaluated the size of two recipient transplant liver patients and showed the liver size in both recipients to increase by an average of 70 cc per day.…”

“…It is thought that this potential bias is acceptable clinically, as review of the literature shows that as a response mechanism, the liver often increases and decreases in size well past 3.4%. [10,[28][29][30] Liver volume assessed 3-4 weeks post portal vein embolisation shows an increase in volume of 5% being associated with improved patient outcomes. [8] Lewis et al 2006 [10] found liver volume reduced by 14% over a six week period following the implementation of a low calorie diet.…”

Introduction: Recent advances in technology have seen the introduction of software assisted image post-processing (SAIP) tools to calculate the volume of the liver from Computed Tomography (CT) images. One such SAIP tool is the semi-automated Philips liver segmentation and analysis package (Endhoven, The Netherlands). The intra-and inter-rater reliability of the liver volumes of 16 participants calculated using this tool was assessed. Methods: Two CT Technologists accessed Abdominal CT data sets and calculated the volume of the liver using the Philips liver segmentation and analysis package. One technologist repeated their calculation. Results: Results demonstrated high intra-rater reliability (ICC 0.9997) and high inter-rater reliability (ICC 0.99994). Analysis with Bland Altman plots showed the mean bias for both intra-and inter-rater reliability to be close to zero with acceptable limits of agreement. Conclusions: This study has shown that liver volume measurements using the Philips SAIP (Endhoven, The Netherlands) can be taken reliably by CT technologists, with confidence that the same results would be obtained between different CT technologists.

Background Obesity has become an increasing problem worldwide during the past few decades. Hence, surgeons and anaesthetists will care for an increasing number of obese patients in the foreseeable future, and should be prepared to provide optimal management for these individuals. This review provides an update of recent evidence regarding perioperative strategies for obese patients. Methods A search for papers on the perioperative care of obese patients (English language only) was performed in July 2019 using the PubMed, Scopus, Web of Science and Cochrane Library electronic databases. The review focused on the results of RCTs, although observational studies, meta‐analyses, reviews, guidelines and other reports discussing the perioperative care of obese patients were also considered. When data from obese patients were not available, relevant data from non‐obese populations were used. Results and conclusion Obese patients require comprehensive preoperative evaluation. Experienced medical teams, appropriate equipment and monitoring, careful anaesthetic management, and an adequate perioperative ventilation strategy may improve postoperative outcomes. Additional perioperative precautions are necessary in patients with severe morbid obesity, metabolic syndrome, untreated or severe obstructive sleep apnoea syndrome, or obesity hypoventilation syndrome; patients receiving home ventilatory support or postoperative opioid therapy; and obese patients undergoing open operations, long procedures or revisional surgery.
