Background: The senior author (A.P.) has performed 70 consecutive breast reconstructions over 3 years using the free deep inferior epigastric perforator (DIEP) and pedicled extended latissimus dorsi flaps. This study set out to compare these two methods of reconstruction by looking at postoperative morphine requirements and lengths of stay in hospital.
Methods: Patient notes were retrospectively reviewed and the total morphine used by patient-controlled analgesia was measured.
Results: The mean morphine per kilogram required by patients who had DIEP flaps (0.21 mg/kg; n = 22) was significantly less than the amount required by patients who had extended latissimus dorsi flaps (0.47 mg/kg; n = 48; p < 0.001). An observed trend also revealed that DIEP flap patients remained in hospital for less time compared with extended latissimus dorsi flap patients, although the difference was not significant (p > 0.01).
Conclusions: This study shows that DIEP flap patients require less postoperative morphine and therefore might experience less pain than extended latissimus dorsi flap patients. DIEP flap patients may also leave the hospital sooner.

Case Summary: A cat aged 12 years and 7 months was referred to a multidisciplinary hospital for investigation of feline injection site sarcoma (FISS) on the left thoracolumbar region. A CT examination of the mass revealed a multi-lobulated mass affecting the body wall, extending from the level of lumbar vertebrae L2 to L4. The mass was excised with 5 cm lateral margins, including resection of the 13th left rib, the caudal edge of the latissimus dorsi (LD) muscle, full-thickness abdominal wall and sections of the lumbar epaxial muscles.

Article Synopsis
- The video article discusses the far posterior or paraspinal approach for treating posterior rib fractures, which enhances intraoperative visibility and minimizes muscle damage.
- This method helps preserve periscapular strength, achieving up to 95% recovery six months after surgery through muscle-sparing techniques.
- The surgical process involves precise skin incision and careful dissection of muscles like the trapezius, rhomboids, and latissimus dorsi to allow for effective access and treatment of the fractures without significant tissue loss.

Left thoracotomy with spiral incision is conventional approach for the repair of descending and thoracoabdominal aortic aneurysms. Because the aneurysms' locations and ranges are various, case-oriented approaches including body postures and the positions of thoracotomy are necessary. Preoperative computed tomography assessment of aneurysms is important for decision making of both operative indication and approach.

In plastic surgery, the reconstructive ladder is a systematic approach used to guide the planning and execution of reconstructive procedures. The use of autologous tissues is preferred in the breast reconstruction process due to the multiple advantages they offer. The latissimus dorsi musculocutaneous flap has been the therapeutic option of choice in these cases, replacing other surgical techniques because of the high adaptability and low complication rates.

Postmastectomy radiotherapy causes capsular contracture due to fibroproliferation of the capsular tissue around the implant. In fibrosis, unlike normal wound healing, structural and functional disorders are observed in the tissues caused by excessive/irregular accumulation of extracellular matrix proteins. It has been reported that transforming growth factor-β3 (TGF-β3) prevents and reverses fibrosis in various tissues or provides scarless healing with its antifibrotic effect.
