Tracheoesophageal fistula (TEF) is a disease characterized by an abnormal connection between the trachea and esophagus. Benign TEF often results from damage induced by tracheal intubation, primarily presenting as exacerbated cough during swallowing, which can be life-threatening in severe cases. However, there is no unified standard for the surgical treatment of TEF. Currently, the choice of surgical method mainly depends on the location, size, and condition of the surrounding trachea. For small to moderate TEFs, tracheal segmental resection and reconstruction is a classic surgical approach. For larger, complex, and refractory TEFs, musculocutaneous flap repair is an ideal option. This article reviews the application of several common musculocutaneous flaps, including the sternocleidomastoid, pectoralis major, and latissimus dorsi, in the repair of benign TEFs, aiming to provide a reference for the clinical diagnosis and treatment of this disease.
ObjectiveTo investigate the effectiveness of free anterolateral thigh Kiss flap in repair of large scalp defect after malignant tumor resection.MethodsBetween December 2012 and December 2016, 18 patients with large scalp defect after malignant tumor resection were treated. There were 16 males and 2 females with an average age of 52.6 years (range, 43-62 years). There were 17 cases of squamous carcinoma and 1 case of dermatofibrilsarcoma protuberan. The size of scalp defect ranged from 15 cm×10 cm to 17 cm×12 cm after resection of tumors. The scalp defects were repaired with the free anterolateral thigh Kiss flap. And the size of flap ranged from 15 cm×6 cm to 20 cm×8 cm. The skull was completely resected in 2 cases, and repaired with Titanium mesh. The sizes of skull defects were 12 cm×10 cm and 10 cm×8 cm. The donor site was sutured directly.ResultsEighteen flaps survived with primary healing of wounds; and healing by first intention was obtained at the donor sites. One patient died because of intracranial metastasis at 5 months after operation, and no local recurrence occurred in the other 17 patients. The follow-up time ranged from 6 months to 4 years (mean, 26.6 months). The results of both appearance and function were satisfactory, without ulceration during follow-up. No obvious scar was found at donor sites and no obvious impairment was observed after harvesting free anterolateral thigh flap.ConclusionLarge scalp defects after malignant tumor resection can be effectively repaired by free anterolateral thigh Kiss flap. The donor site can be sutured directly, without skin grafting, thus avoiding the secondary donor site.
