RATE: A Customizable, Portable Hardware/Software System for Analysing and Teaching Human Performance in the Operating Room

The methods reported here were developed to support observation and scoring of teams performing laparoscopic cholecystectomy, a surgical procedure to remove the gallbladder. The procedure created an ideal situation due to its frequency of performance and relatively short time length of procedure (1–1.5 hours from patient entering to patient leaving the room). The challenges include the fact that a standard team is made up of at least five people: anaesthesiologist, attending surgeon, resident surgeon, scrub tech, circulating nurse; in our institution, a medical student who acts as the laparoscopic camera operator and an anaesthetist is most often included too. Others such as technicians and nurses-in-training may also be present. Reliability of the data becomes an issue when the observer is confronted with tracking multiple events by multiple test subjects when evaluating a team (Simon and Ericsson 1993).
Depth perception and sad indirect viewing: reflections on keyhole surgery

Keyhole surgery is performed remotely. Trocars, narrow-bore tubes containing the camera and instruments, are inserted in the patient to reach the site of operation, which is viewed at a TV monitor. Compared with conventional surgery, incisions are minimal: pain, infection and post-operative care may be reduced. However, the development of keyhole surgery has been technology-driven with little consideration for human information processing. Compared with conventional surgery, seven-fold increases in complication rates following keyhole surgery have been reported (Antia, 1994). The most popular procedure, cholecystectomy (gall-bladder removal), presents a risk of potentially fatal rupture of the bile duct (Treacy & Johnson, 1995).
Error Traps and Recurrent Accidents
Published in James Reason, The Human Contribution, 2017
Cholecystectomy involves the removal of the gall bladder, a floppy sac of bile lying under the liver, frequently because gall stones have formed in the sac. Twelve years ago, the surgeon would have made a six-inch incision in the abdomen that would require the patient to have a week’s stay in hospital to heal. Now, with the advent of laparoscopic surgery, all that is required are a few tiny incisions that enable the surgeon to insert a miniature camera and the required instruments. The procedure is guided by a TV screen. This operation, often done as day surgery, is termed laparoscopic cholecystectomy or ‘lap chole’.

Laparoscopic cholecystectomy (LC) is currently one of the most commonly performed minimally invasive (abdominal) procedures in elective and emergency settings. (Sugrue et al. 2019) The procedure is considered the standard surgical treatment for patients with symptomatic cholelithiasis, cholecystitis, gallstone pancreatitis and gallbladder polyps. (Priego et al. 2009; Soper and Malladi 2022) The procedure has evolved into a relatively safe and tolerable daycare procedure. However, there is high variability in perioperative findings. (Griffiths et al. 2019; Ward et al. 2022) LC can be relatively easy in patients with a floppy, non-inflamed pink gallbladder. However, the procedure can be challenging in patients with dense adhesions and severe cholecystitis. These high complex procedures can result in prolonged OR time, more blood loss, and an increased risk of complications. (Atta et al. 2017; Madni et al. 2018; Sugrue et al. 2019)

Laparoscopic surgery is a commonly used minimally invasive surgery (MIS) technique, common for procedures such as cholecystectomy (gall bladder removal) surgery and gynecologic surgery. It brings many benefits to the patients, including less pain and quicker recovery compared to open surgery. However, laparoscopic surgery has also created new issues for surgeons compared to open surgery. In laparoscopic surgery, the image of the abdominal organs is acquired by a laparoscope and sent to a video monitor. Surgeons operate while looking at the surgical field image on the monitor. The difficulties that surgeons usually encounter in laparoscopic surgery are physical fatigue from the awkward postures caused by the positioning of the monitors and the long duration usage of the monitors.
Patient-specific fluid–structure interaction model of bile flow: comparison between 1-way and 2-way algorithms

Other risk factors for gallstone formation are female gender (gallstones are twice as common in women compared with men), obesity, estrogen supplementation, multiparous state, advancing age, hyperlipidemia, inborn disorders of bile metabolism, and family history of gallstones (Kay Washington 2009).Cholecystectomy is the most commonly performed abdominal operation for the treatment of patients suffering from gallbladder disease in Western countries (Ooi et al. 2004). Nevertheless, the operation outcome is not always positive (Kuchumov et al. 2011; Mohan et al. 2014) including bile duct injury; injuries to the intestine, bowel and blood vessels; bile leakage; deep vein thrombosis (Khan et al. 2007). Serious complications result in part from patient state, surgical inexperience, and the technical constraints.
