In-bag manual morcellation is a safe alternative procedure after FDA's discouragement of electronic power morcellator. The traditional wedging (V-type incision) or semicircular coring (C-type incision or ExCITE) method are the most common morcellation techniques. For beginners, it is somehow not that easy to get familiar with these methods. No teaching or learning experiences were reported. Therefore, we developed a dome-type (modified C-incision) technique to manually morcellate uteri leiomyoma or uterus at the time of laparoscopic surgery and report perioperative outcomes and the learning experiences of our residents for this technique from our two years of experience.

Background: In-bag manual morcellation is a safe alternative procedure after FDA's discouragement of electronic power morcellator. The traditional wedging (V-type incision) or semicircular coring (C-type incision or ExCITE) method are the most common morcellation techniques. For beginners, it is somehow not that easy to get familiar with these methods. No teaching or learning experiences were reported.

Objective: To describe using a dome-type (modified C-incision) technique to manually morcellate uteri leiomyoma or uterus at the time of laparoscopic surgery and report perioperative outcomes and the learning experiences of our residents for this technique from our two years of experience.

Study Design: Retrospective review of consecutive laparoscopic myomectomies or hysterectomies performed between May 2020 and September 2022 in which the specimen was manually morcellated using the dome-type technique by surgeon or trainees.

Inclusion Criteria:

• Women at any age undergoing laparoscopic surgeries with dome-type morcellation

Exclusion Criteria:

• Women with extremely huge specimen (>2000 gm)
