Study Objective:
To evaluate the feasibility, efficiency, and safety of manual morcellation in laparoendoscopic single-site (LESS) supracervical hysterectomy.
Design:
Retrospective study (Canadian Task Force classification II-2).
Setting:
A teaching hospital.
Patients:
One hundred and ninety patients with symptomatic uterine leiomyomas and/or adenomyosis who underwent LESS supracervical hysterectomy.
Interventions:
Manual morcellation through the umbilical wound.
Measurements And Main Results:
Time of operation, blood loss volume, specimen weights, rate of morcellation, requirement for blood transfusion, hospital length of stay, and prevalence of postoperative cyclic spotting were recorded. The median weight of the uterine corpus was 245 g (range, 100-1960 g). The median total operation time was 69 minutes (range, 36-183 minutes). The median volume of blood loss was 50 mL (range, 10-850 mL). The median level of hemoglobin reduction was 1 g/dL (range, -1 to 3.2 g/dL). The incidence of intraoperative blood transfusion was 3.2%, and the mean manual morcellation rate was 38.9 ± 15 g/minute. The incidence of postoperative cyclic spotting was 10.5%.
Conclusion:
Safe and effective LESS surgery requires a minimal surgical incision compared with conventional laparoscopic surgery and laparotomy. Manual morcellation was found to be effective and safe in removing solid tumors in this population.

Load along a Single Axis
Consider a beam of length L subjected to a varying load, which is a combination of parabolic and trapezoidal load distribution along the x-axis. In this case, it is essential to determine the resultant loads, their locations, and...
