[Clinical application of supraclavicular flap for oncologic reconstruction of hypopharynx and upper esophagus].

Objective: To assess the efficacy of supraclavicular artery island flap (SCAIF) for the reconstruction of hypopharynx and upper esophagus. Methods: The SCAIF procedure on was used in 10 patients, including 8 with hypopharygeal carcinomas, 1 with esophageal carcinoma and neck skin invasion and 1 with hypopharyngeal leiomyosarcoma, at the Otorhinolaryngology Hospital, the First Affiliated Hospital, Sun Yatsen University between December 2015 and June 2017. The sizes of the flaps were measured in (4-8) cm×(5-12) cm. Clinical indexes such as harvesting time and survival were recorded. Results: Harvesting time for SCAIF ranged from 20 to 30 minutes, averaging 26 minutes. Nine flaps survived, one flap had partially necrosis. Functional outcomes were excellent and the donor sites were direct closed without complications. Conclusions: SCAIF is a versatile, reliable, and easily harvested flap, with good cosmetic and functional outcomes for reconstructing the defects of hypopharynx and upper esophagus.

[Therapy of adult-onset laryngeal papilloma: integrallty submucosal dissection of the tumor by CO2 laser].

Objective: To evaluate the feasibility and efficacy of the integrallty submucosal resection of adult-onset laryngeal papilloma by CO2 laser. Methods: A group of 64 cases (36 males and 28 females, multipe lesions 54 cases and single lesion 10 cases, aged 18-75 years, mean age 43.13 years) with adult-onset laryngeal papilloma encountered in the first affliated hospital of Sun Yatsen university from 2009 to 2015 was retrospectively analyzed. All cases were treated with integrallty submucosal dissection of the tumor by CO2 laser, and observed the changes of tumor integral scope, inter-operative, operative processes, postoperative voice quality, postoperative scarring, and the tracheotomy conditions, which were analysed and evaluated. Results: A total of 64 patients were followed up from 1 year to 5 years. Preoperative tumor integral scope of these patients averaged of 7.00. A total of 62 cases kept 0 score of the tumor integral scope for at least one year, which lead to a clinical cure rate of 96.9%. The inter-operative averaged of 25.7 months. The total operative processes of these patients were 87 times (mean time 1.36). Four cases resulted in postoperative scarring. However these was a good result in postoperative voice quality with a mean score 4.25. As to the changes of tumor integral scope, all cases got a declining score (mean score 6.72), which resulted in a remission rate of 100%. Conclusion: The integrallty submucosal dissection of adult-onset 1aryngeal papilloma by CO2 laser was an effective way to reduce the tumor integral scope; lengthen their inter-operative; decrease the operative processes, avoid the occurrence of tracheotomy; and improve the postoperative voice quality. Most of the patients could even be cured ultimately.

Predictors of acid suppression success in patients with chronic laryngitis.

BACKGROUND: Up to 50% of the patients suspected of reflux laryngitis syndrome failed to respond to acid suppression therapy. However, predictors of acid suppression success have not been determined. METHODS: Consecutive patients with chronic laryngitis were enrolled prospectively. All the patients underwent laryngoscopy, esophagogastroduodenoscopy and 24-h multichannel intraluminal impedance and pH (MII-pH) monitoring before receiving rabeprazole 10 mg b.i.d. for 3 months. Patient was considered as a responder to acid suppression if the chief laryngeal complaint score during the last week since last interview had decreased by at least 50% after the start of therapy compared with baseline. Cox regression analysis was used to determine the independent predictors of acid suppression success. KEY RESULTS: Of 92 patients (age 42.4 ± 14.3 years, 50 women), 42 (45.7%) responded to acid suppression after 3 months. Gastroesophageal reflux disease was defined in 22 patients, of whom 19 patients had pathological distal esophageal acid exposure and 5 were defined as erosive esophagitis. The time to response showed a significant hazard ratio for patients with increased distal esophageal acid exposure time (ß: 0.93; HR: 2.55; 95% CI: 1.24-5.24; P = 0.011) and increased laryngopharyngeal bolus exposure time (BET; ß: 0.96; HR: 2.61; 95% CI: 1.36-5.00; P = 0.004). The latter had the best Youden Index (0.34) and accuracy (68.5%). CONCLUSIONS & INFERENCES: The success of acid suppression on chronic laryngitis could be predicted using reflux parameters detected by MII-pH, among which increased laryngopharyngeal BET is the best.
