Objective: To characterize nicotinic cholinergic receptors (cholinoceptors) in frog rectus abdominis and mouse esophagus. Material and Methods: Isolated preparations of mouse esophagus and frog rectus abdominis were separately mounted in organ baths filled with Krebs and Ringer solutions respectively. The organ bath medium was continuously gassed with 95% O 2 and 5% CO 2 and the temperature was...

Ventral hernia formation is a common complication of rectus abdominis musculocutaneous flap harvest. The site and extent of harvest of the flap are known contributing factors. Therefore, an accurate location of the arcuate line of Douglas, which marks the lower extent of the posterior wall of the rectus sheath, may be relevant before harvesting the flap. This study is aimed at determining the p...

Endometriosis is characterized by an abnormal existence of functional endometrial tissue outside the uterine cavity, typically occuring within the pelvis of women in reproductive age. We report two cases with endometriosis of the abdominal wall; the first one in the rectus abdominis muscle and the second one in the surgical scar of previous caesarean incision along with the rectus abdominis mus...

SUMMARY Adjuvant treatment planning can change after breast cancer resection and definitive pathological examination. Radiation therapy is often chosen as a supplementary treatment. Rectus abdominis-based muscle flaps are one of the main choices when breast reconstruction plans must be changed from implant-based to autologous methods. We herein report a case in which the patient's own tissue ex...

Fecal stomal incontinence is a problem that continues to defy surgical treatment. Previous attempts to create continent stomas using dynamic myoplasty have had limited success due to denervation atrophy of the muscle flap used in the creation of the sphincter and because of muscle fatigue resulting from continuous electrical stimulation. To address the problem of denervation atrophy, a stomal s...

[Purpose] The aim of this study was to investigate the influence of the craniocervical posture on abdominal muscle activities in hook-lying position. [Subjects] This study recruited 12 healthy young adults. [Methods] Each subject was asked to adopt a supine position with the hip and knee flexed at 60°. Surface electromyographic signals of transversus abdominis/internal oblique, rectus abdominis...

BACKGROUND Abdominoperineal excision is performed in patients with locally advanced, low rectal carcinoma. Reconstruction of the dorsal vagina and perineum using the vertical rectus abdominis myocutaneous flap following extensive surgery results in favorable surgical outcome and quality of life. However, the rectus abdominis muscle, as part of the anterior abdominal wall, may develop fibrous le...

The purpose of abdominal wall reconstruction is to prevent hernias and protect the abdominal viscera. In cases involving full-thickness defects of the rectus abdominis muscle, the muscle layer should be repaired. We present 2 cases in which full-thickness lower rectus abdominis muscle defects were reconstructed using vastus lateralis-anterolateral thigh flaps. The pedicled vastus lateralis-ante...

OBJECTIVE To assess donor-site morbidity and survival of the rectus abdominis muscle with an overlying skin graft after free tissue transfer to a medial femorotibial defect in dogs. STUDY DESIGN Experimental study. SAMPLE POPULATION Phase 1: 6 canine cadavers; phase 2: 7 adult mixed-breed dogs. METHODS Phase 1: The rectus abdominis muscle was removed from canine cadavers, muscular and vas...
