ClinConnect Summary

This study looks back at past liver surgeries to see if two scoring tools can predict how difficult a minimally invasive liver resection will be. Researchers want to test the Iwate difficulty score and the Institut Mutualiste Montsouris (IMM) score for both laparoscopic and robotic liver surgeries. They will analyze cases from 2000 through 2020 to see how well these scores reflect real surgery difficulty and safety, and they may compare robotic versus traditional laparoscopic approaches using statistical methods. No results are shared yet.

Who can be involved and what to expect: about 150 adults up to age 79 who had a minimally invasive liver resection at a single hospital (Methodist Health System, Dallas) between 2000 and 2020 are eligible. Both men and women can be included, and the study may include surgeries that used different MILR methods (laparoscopic, hand-assisted, robotic-assisted) and sometimes additional procedures. People under 18 or those who donated a liver for transplant are not eligible. This is a review of existing medical records, not a new treatment or trial, and individual patient data will not be shared publicly.

Eligibility criteria

• Inclusion Criteria:
• • All consecutive patients operated at a single institution during a fixed period
• • Most recent operation date allowed (up till December 31, 2020, to allow three months follow-up).
• • All minimally invasive hepatectomy approaches can be included, including lap- assisted (hybrid), hand-assisted, robotic-assisted and pure laparoscopy.
• • The data of all patients including those that had repeat liver resections, concomitant surgeries (e.g. colectomies, hilar lymph node dissection, enbloc resections) may be included
• • Patients with no "liver tumors" such as recurrent pyogenic cholangitis/ gallbladder may be included
• • The site of the "lesion/ pathology" will be considered as the tumor site, size will be considered less than 3 cm unless tumor invades the liver.
• Exclusion Criteria:
• • • Patients \< 18 years of age
• • Patients with liver transplant living donor hepatectomies
