Abstract:
Objective:The purpose of this study was to introduce an endoscopic approach to harvest latissimus dorsi muscle(LDM)flap using a single transverse axillary incision and evaluate its safety and efficacy to repair the chest deformities of Poland syndrome.Methods:Poland syndrome patients were recruited prospectively to repair the thoracic wall deformity plus breast reconstruction(combined with breast implant insertion) using the endoscopic approach to transfer LDM flap with single transverse axillary incision in the Department of Aesthetic and Reconstructive Breast Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from October 2015 to January 2018. Information including patient demographics, LDM area, implant size, contralateral symmetry surgery, operative time(endoscopic time for LDM flap harvesting, endoscopic anterior subcutaneous pocket creating time and total time), the survival of LDM flap, deformity of thoracic wall and back and post-operative complications were collected. The pain visual analog scale was used to assess the severity of postoperative pain. The Breast-Q reconstruction module was used to evaluate patients’ psychosocial well-being and satisfaction with the outcome. The disabilities of the arm, shoulder, and hand (DASH) outcome questionnaire was used to evaluate patient upper extremity disabilities. A paired t-test was utilized to analyze the difference between the preoperative and postoperative score of the Breast-Q and DASH questionnaire. Results:Twenty-eight patients were recruited in this study, including 11 males and 17 females aged (22.5±3.9) years old with a body mass index of (20.5±6.1) kg/m 2. Two patients received contralateral implant augmentation and two received fat grafting for breast symmetry. The postoperative follow-up time was (50.4±23.1) months. All the reconstructed breasts or thoracic walls was in a good shape. All the LDM flap survived with good blood supply. The postoperative pain was mild, and there was no obvious abnormality of the thoracic wall and back. The area of harvested LDM flap was (437.2±110.0) cm 2. The size of the implant used for breast reconstruction was (240.4±46.0) ml. Total operation time was (169.4±16.1) minutes for patients without contralateral symmetrical surgery. The endoscopic time for LDM flap harvesting was (69.0±13.9) minutes. The endoscopic anterior subcutaneous pocket creating time was (32.8±6.0) minutes. The postoperative drain time was (7.6±1.4) days. The postoperative complications included one case of early seroma, one case of wound dehiscence, one case of flap malposition. The pain visual score of the patient was 2.7±0.5 on the first day after the operation and decreased to 0.8±0.4 after 1 week. The score of satisfaction with breast before surgery was 27.8±20.8, psychosocial well-being score was 49.6±17.0. The postoperative score of satisfaction with breast was 63.1±11.6, and psychosocial well-being score was 68.1±16.7. The postoperative score of satisfaction with breast ( t=-9.000, P=0.008) and psychosocial well-being ( t=-6.543, P<0.001) were significantly higher than those before surgery. The score of DASH was 3.7±3.3 before surgery and 4.0±3.7 after surgery respectively, with no statistically significant differences ( t=-1.160, P=0.276). All patients were highly satisfied with the result of the surgery. Conclusions:The endoscopic approach to transfer latissimus dorsi muscle flap using a single transverse axillary incision provides a safe and efficient way to repair thoracic wall deformities in Poland syndrome patients with a high satisfaction rate, a better aesthetic outcome, and a minimal complications rate.
