AIM:To compare postoperative complications and prognosis of esophageal squamous cell carcinoma patients treated with different routes of reconstruction. METHODS:After obtaining approval from the Medical Ethics Committee of the Sun Yat-Sen University Cancer Center, we retrospectively reviewed data from 306 consecutive patients with histologically diagnosed esophageal squamous cell carcinoma who were treated between 2001 and 2011. All patients underwent radical McKeown-type esophagectomy with at least two-field lymphadenectomy. Regular follow-up was performed in our outpatient department. Postoperative complica-tions and long-term survival were analyzed by treatment modality, baseline patient characteristics, and operative procedure. Data from patients treated via the retrosternal and posterior mediastinal routes were compared. RESULTS:The posterior mediastinal and retrosternal reconstruction routes were employed in 120 and 186 patients, respectively. Pulmonary complications were the most common complications experienced during the postoperative period (46.1% of all patients; 141/306). Compared to the retrosternal route, the posterior mediastinal reconstruction route was associated with a lower incidence of anastomotic stricture (15.8% vs 27.4%, P = 0.018) and less surgical bleeding (242.8 ± 114.2 mL vs 308.2 ± 168.4 mL, P < 0.001). The median survival time was 26.8 mo (range:1.6-116.1 mo). Upon uni/multivariate analysis, a lower preoperative albumin level (P = 0.009) and a more advanced pathological stage (pT; P = 0.006; pN; P < 0.001) were identified as independent factors predicting poor prognosis. The reconstruction route did not influence prognosis (P = 0.477). CONCLUSION:The posterior mediastinal route of reconstruction reduces incidence of postoperative complications but does not affect survival. This route is recommended for resectable esophageal squamous cell carcinoma.

Thyroidectomy for Massive Goiter Weighing more than 500 Grams. Technical Difficulties, Complications and Management. Review

引用

Surgical Science 2011年第5期2卷 278-284页

作者： Norman Oneil Machado 不详

Background: Multinodular goiter is a relatively common thyroid disorder with a marked female preponderance. Most of these goiters weigh less than 100 grams with those weighing more than 500 grams being exceptional. The massively expanding goiter due to the strategic anatomic location of thyroid gland, in addition to being cosmetically disfiguring can seriously compromise the patency of the trachea and oesophagus. Thyroidectomy for such goiters is a surgical challenge due to the possible association of tracheomalacia, retrosternal extension, skin involvement and the difficulty in intubation and dissection of the thyroid gland due to distorted and displaced anatomy. Material and methods: While presenting 2 patients who underwent thyroidectomy for glands weighing more than 500 grams, the literature is reviewed to analyze the technical difficulties and approach in such patients and the frequently encountered complications in them and their management. Results: A review of the literature revealed an additional 7 cases of patients who had undergone thyroidectomy for glands weighing more than 500 grams. Massively enlarged goiter was often associated with tracheomalacia, tracheal stenosis and retrosternal extension. Difficulty during surgery was most often encountered in establishing the airway and in exposure of the gland particularly when the skin was involved. The predominant postoperative complications were related to respiratory distress as a consequence of tracheomalacia and tracheal stenosis. Conclusion: In spite of the technical challenge related to the airway, and thyroidectomy, surgery continues to be the best option in experienced hands due to its distinct advantage of its immediate effect and complete resolution of compressive symptoms.
