Implication of enhanced recovery after surgery in the surgical management of hypopharyngeal squamous cell carcinoma / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the safety and efficacy of enhanced recovery after surgery (ERAS) in the clinical management of hypopharyngeal squamous cell carcinoma (HSCC). Methods: In this retrospective study, a total of 168 patients with pyriform sinus carcinoma in Qilu Hospital of Shandong University from January 2015 to January 2019 were divided into two groups, based on the different perioperative interventions that patients received, i.e. the ERAS group (n=64) and the conventional group (n=104), including 164 males and 4 females, whose ages ranged from 42 to 84 years old. The difference between two groups in the operative time, postoperative nutritional status, incidences of postoperative complications and postoperative hospitalization time were compared using the student's t test, Chi-squared test or Fisher's exact test. Results: Compared with the conventional group, patients in the ERAS group had significantly shorter operative time [(166.8±58.2) min vs. (183.3±39.9) min,t=-2.72, P=0.031], higher levels of postoperative serum albumin [(38.3±4.2) μmol/L vs. (36.6±3.3) μmol/L, t=2.73, P=0.007] and more body weight [(65.4±9.4) kg vs. (62.1±9.4) kg, t=2.22, P=0.028], lower incidences of postoperative subcutaneous infection [7.8% (5/64) vs. 20.2% (21/104), χ²=4.64, P=0.03] and severe pneumonia [4.7% (3/64) vs. 15.4% (16/104), χ²=4.52, P=0.03], and shorter postoperative hospitalization time [(16.5±3.9) d vs. (18.2±4.3) d, t=-2.65, P<0.05]. Conclusion: ERAS is effective and safe in the surgical management of HSCC, with benefits in reducing the operative stress via saving operation time, shortening the hospitalization time, ameliorating nutritional status and decreasing the incidences of complications.

Surgical treatment of advanced laryngeal cancer with preservation of laryngeal function / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To explore the surgical methods for advanced laryngeal cancer and long term effects of laryngectomy.</p><p><b>METHODS</b>Two hundred and thirty-eight cases of laryngeal cancer at different stages, including 103 cases with supraglottic cancer, 118 cases with glottic cancer, 3 cases with subglottic cancer, and 14 cases with recurrent cancer, underwent different kinds of operation from 2000 to 2010. The TNM classifications were as follows: T3 168 cases, T4 70 cases. Stage III 145 cases, Stage IV 93 cases. N0 134 cases,N1 64 cases,N2 38 cases, and N3 2 cases. The effects of operation, especially with the preservation of laryngeal function, was analyzed. The disease-free survival rate was calculated by Kaplan-Meier methods.</p><p><b>RESULTS</b>Partial laryngectomy was performed on 142 of the 238 cases (59.7%). Total laryngectomy was performed on 96 cases. In 142 patients who received partial laryngectomy with preservation of laryngeal function, the trachea cannula was extracted in 90 patients, with the decannulation rate as 63.4%. The nasal feeding tube was removed and peroral feeding was recovered in all patients. The patients undergoing partial laryngectomy succeeded in phonation. The 3 years and 5 years disease-free survival rates in all patients were 81.4% and 59.5%. The 3 years and 5 years disease-free survival rate of partial laryngectomy were 82.9% and 64.3%. The 3 years and 5 years disease-free survival rates in total laryngectomy were 79.2% and 52.4%. There was no significantly different between the two groups (χ(2) = 2.478, P = 0.115).</p><p><b>CONCLUSION</b>For the advanced laryngeal cancer, it is possible to preserve the laryngeal function without compromising the remote survival rate by detailed pre-operational estimation, properly selected operation and skilled surgical practice.</p>

Comprehensive treatment of 352 cases with hypopharyngeal cancer / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To review the experience of different surgical construction methods and comprehensive treatments for hypopharyngeal cancer.</p><p><b>METHODS</b>Three hundred and fifty-two cases (According to UICC 2002 criteria, stage I, 3; II, 31; III, 134; IV, 184) with hypopharyngeal cancer were retrospectively reviewed from 1999 to 2005 in the Department of Otorhinolaryngology of Qilu Hospital of Shandong University, including 321 males and 31 females. The median age was 58 years old, ranged from 26 to 82 years old. All the tumors originated from the pyriform sinus (272), posterior pharyngeal wall (61), postcricoid area (19). There were no distant metastasis. Two hundred and fourty-one cases were surgically treated with laryngeal functions preserved and 111 cases without laryngeal functions preserved. All the patients received modified neck dissection, including both unilateral (247 patients) and bilateral (105 patients). Pharyngoesophageal defect reconstruction methods in cases with laryngeal functions preserved were: direct suture in 137, pectoralis major musculocutaneous flap in 62, split graft in 2, pectoralis major musculocutaneous flap combined with the split graft in 5, stomach pulling-up in 12, colon interposition in 23 patients. While in cases without laryngeal functions preserved the methods includes: direct suture in 54, laryngotracheal flap in 54 patients, pectoralis major musculocutaneous flap in 7, laryngotracheal flap combined with pectoralis major musculocutaneous flap in 8, stomach pulling-up in 22, colon interposition in 3 patients. All patients received radiotherapy postoperatively (dose 55 - 75 Gy).</p><p><b>RESULTS</b>The overall 3 and 5 year survival rates were 65.1% (229/352) and 53.6% (142/265), respectively. For stage I, the 5 year survival rate was 3/3, stage II, 80.6%(25/31), stage III, 65.0% (67/103), stage IV, 36.7% (47/128). The 3 and 5 year survival rates in functionally preserved group were 68.0% (164/241) and 59.7% (114/191), respectively, while in non-functionally preserved group were 58.6% (65/111) and 37.8% (28/74), respectively. The cervical lymph node metastasis was found in 239 sides. Pathologic findings showed that well, moderately and lower differentiated squamous cell carcinomas were 84, 163, 105 cases, respectively. Laryngeal functions (voice, respiration and deglutition) were completely restored in 169 patients and partially restored (voice and deglutition) in 72 patients.</p><p><b>CONCLUSIONS</b>Combined surgery and radiotherapy are the best choice for hypopharyngeal cancer. The continuity of the pharyngoesophagus is restored and the laryngeal function is preserved as far as possible. The preservation of laryngeal function and the laryngeal and pharyngeal reconstruction are based on the premise that the tumor was excised completely.</p>

<p><b>OBJECTIVE</b>Canine model established for tracheal defect reconstruction, to investigate the outcome of tracheal reconstruction with combination of polypropylene and flap.</p><p><b>METHODS</b>About 3.5 to 4 centimeter cervical trachea was resected and replaced with artificial trachea made from monofilament knitted polypropylene and surgical flap. Covered stent was implanted postoperatively. Survival period and quality of life were recorded, bronchofibroscopy, X-ray films and HE sections were performed.</p><p><b>RESULTS</b>Six dogs survived well and another two died. The causes of death were respiratory failure in 1 and infection in another. Stenosis of anastomosis in 1 was recorded during survival period. The dogs started drinking and eating on the second postoperative day, no dyspnea was found. The animals were sacrificed at 2, 4, 8 weeks and 6 months after surgery. Soft tissue growth was found in polypropylene net 2 weeks after surgery and more at 4 weeks. The polypropylene net was covered completely with soft tissue at 8 weeks and 6 months postoperatively, the hardness and sustentation degree were enhanced following the growth and fibrosis of soft tissue. The squamous epithelium and columnar epithelium were observed healing well by HE staining method.</p><p><b>CONCLUSIONS</b>One-stage operative artificial trachea made from monofilament knitted polypropylene which has good histocompatibility and surgical flap is the closer artificial trachea to native trachea. It has a promising prospect in clinical use.</p>

Diagnosis and surgical management of carotid body tumor as well as blood vessel prosthesis' role / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To analyse the diagnostic and therapeutic aspects of carotid body tumor (CBT).</p><p><b>METHODS</b>Seven patients with CBT had been hospitalized between 2003 and 2006. The clinical data was analyzed retrospectively. The preoperative evaluation included angiography in 7 patients. Most of them had an asymptomatic cervical lateral mass. Only one patient had the hoarseness and buckling and was given radiation therapy alone. Six of seven patients with carotid body tumour underwent surgery. Simple tumor excision was accomplished in 4. Carotid artery resection with the tumor was required in 2 patients and in the both, interposition of a 7 mm polytetrafluoroethylene graft was performed . During the resection, temporary carotid shunt was required in the two patients.</p><p><b>RESULTS</b>All tumors by surgery were identified as carotid paragangliomas without evidence of malignancy. There was no mortality and no hemiplegia. After surgery, temporary cranial nerve dysfunction was noted in one case. In the follow-up period of 2 months to 2 years, no recurrent disease occurred. The patient's tumor who accepted radiotherapy was in the stable stage under the half year follow up, and the follow up would be further continued.</p><p><b>CONCLUSIONS</b>With non-invasive investigation and arteriography it was possible to obtain an early and precise diagnosis. The surgical management was the major treatment of these tumors. The pattern of operation should be chosen according to the relation of tumor and carotid. The decision to perform simple tumor excision or additional arterial resection was based on diagnostic preoperative and after the arterial resection the polytetrafluoroethylene graft would be used for carotid reconstruction.</p>
