Standardized Approach for Laparoscopic Hemispheric Liver Resection for Segments 7 and 8

Area of Science:

• Hepatobiliary Surgery
• Minimally Invasive Surgery
• Surgical Techniques

Background:

• Assessing the efficacy of the standardized "can-opener method" for laparoscopic hemispheric hepatectomy.
• Evaluating the surgical procedure for liver segments 7 and 8 resections.

Purpose of the Study:

• To determine if the "can-opener method" is adequate for hemispheric hepatectomy in segments 7 and 8.
• To analyze short-term outcomes of this standardized surgical technique.

Main Methods:

• Retrospective analysis of 42 patients undergoing laparoscopic hemispheric liver resection.
• Classification of patients into two groups based on procedure standardization timing.
• Comparison of short-term outcomes between the two patient groups.

Main Results:

• The standardized technique showed significant improvements in operation time, blood loss, and hospital stay.
• Postoperative complications (Clavien–Dindo Grade I and II) were reduced in the standardized group.
• All patients achieved negative surgical margins with no 90-day mortality.

Conclusions:

• The standardized "can-opener method" is an adequate and safe surgical procedure for hemispheric hepatectomy in segments 7 and 8.
• This technique facilitates effective liver resection with favorable short-term outcomes.
• The "can-opener method" represents a valuable approach for complex liver surgeries.
