Carbon dioxide insufflation of the peritoneal cavity for laparoscopic surgery offers a unique opportunity to measure some mechanical properties of the human abdominal wall that hitherto have been difficult to obtain. The movement and change of the abdominal wall during insufflation to a pressure of 12 mmHg was studied in 18 patients undergoing laparoscopic(More)
Laparoscopic surgery requires inflation of the abdominal cavity and this offers a unique opportunity to measure the mechanical properties of the living abdominal wall. We used a motion analysis system to study the abdominal wall motion of 18 patients undergoing laparoscopic surgery, and found that the mean Young's modulus was 27.7+/-4.5 and 21.0+/-3.7 kPa(More)
There is no established method for defining when a surgeon reaches the proficiency plateau in performing a specific operation. The published literature refers to “learning curves” based on retrospective evaluation of operative time, conversion rates, morbidity etc., which lack objectivity and do not address individual human factors. A more useful study of(More)
The type of stent used for the management of patients with malignant dysphagia is chosen according to subjective physician’s preference. There is no recent study available to provide updated evidence on early outcomes related to the use of different types of stents. A literature search was performed using Embase, MEDLINE, Cochrane Library, and Google(More)
OBJECTIVE To compare intraoperative cardiac function, postoperative cognitive recovery, and surgical performance of laparoscopic cholecystectomy with abdominal wall lift (AWL) versus positive-pressure capnoperitoneum (PPCpn). SUMMARY BACKGROUND DATA AWL has been proposed as an alternative approach to PPCpn to avoid adverse cardio-respiratory changes.(More)
Attention is important for the skilful execution of surgery. The surgeon’s attention during surgery is divided between surgery and outside distractions. The effect of this divided attention has not been well studied previously. We aimed to compare the effect of dividing attention of novices and experts on a laparoscopic task performance. Following ethical(More)
BACKGROUND Mental training is rehearsal of mental imagery without physically performing the task. The aim of the study was to perform systematic review and meta-analysis on all the available data to evaluate the role of mental training in the acquisition of surgical technical skills. METHODS The following search databases were used: EMBASE, MEDLINE, Web(More)
This study hypothesized that patients in whom bradycardia and hypotension develop with induction of positive-pressure capnoperitoneum have an underlying autonomic cardiovascular dysfunction. A case–control study was conducted to examine the baseline autonomic function of patients in whom bradycardia and hypotension develop with induction of(More)
BACKGROUND The aim of this study was to review a series of consecutive percutaneous cholecystostomies (PC) to analyse the clinical outcomes. METHODS All patients who underwent a PC between 2000 and 2010 were reviewed retrospectively for indications, complications, and short- and long-term outcomes. RESULTS Fifty-three patients underwent a PC with a(More)
UNLABELLED BACKGROUND A significant proportion of surgical patients are unintentionally harmed during their hospital stay. Root Cause Analysis (RCA) aims to determine the aetiology of adverse incidents that lead to patient harm and produce a series of recommendations, which would minimise the risk of recurrence of similar events, if appropriately applied(More)
