RESUMO
OBJECTIVE: Concurrent chemoradiotherapy (CCRT) is often performed after total pharyngo-laryngo-esophagectomy (TPLE) or total laryngectomy (TL). Hypothyroidism is one of the side-effects of CCRT. The objective of this study was to ascertain the timing of onset and severity of latent hypothyroidism among patients who underwent radiotherapy (RT) or CCRT after TPLE or TL, using thyroid-stimulating hormone (TSH) as a biomarker, and to explore methods of preventing its development. METHODS: Participants comprised 21 patients who underwent these treatments at Tokyo Medical University Hachioji Medical Center between May 2009 and December 2013. TSH, free thyroxine 3, and free thyroxine 4 levels were used as indicators of thyroid function, and thyroid hormone was administered for TSH levels ≥15 µU/mL. RESULTS: Post-radiotherapeutic TSH levels in 17 of the 21 patients (81%) were not within the reference value, and 10 (48%) required thyroid hormone therapy. Pharmacotherapy was initiated within 1 year in 5 of these 10 patients (50%), and between 1 and 3 years in the remaining 5 patients. No patient who did not undergo thyroidectomy required hormone therapy. Early evaluation of thyroid function appears important when postoperative RT, including CCRT, is performed in combination with TPLE or TL. CONCLUSION: Our study suggested that postoperative CCRT or RT after TPLE or TL, especially hemithyroidectomy, carries a high risk for hypothyroidism.

Background: Total pharyngolaryngoesophagectomy (TPLE) is considered as a curative treatment for hypopharynx cancer and cervical esophageal carcinomas (HPCECs). Traditional pharyngo-gastric anastomosis is usually performed manually, and postoperative complications are common. The aim of this study was to introduce a new technique for mechanical anastomosis and to evaluate perioperative outcomes and prognosis. Methods: From May 1995 to Nov 2021, a series of 75 consecutive patients who received TPLE for a pathological diagnosis of HPCECs at Sun Yat-sen Memorial Hospital were evaluated. Mechanical anastomosis was performed in 28 cases and manual anastomosis was performed in 47 cases. The data from these patients were retrospectively analyzed. Results: The mean age was 57.6 years, and 20% of the patients were female. The rate of anastomotic fistula and wound infection in the mechanical group were significantly lower than that in the manual group. The operation time, intraoperative blood loss and postoperative hospital stays were significantly higher in the manual group than that in the mechanical group. The R0 resection rate and the tumor characteristics were not significantly different between groups. There was no significant difference in overall survival and disease-free survival between the two groups. Conclusion: The mechanical anastomosis technology adopted by this study was shown to be a safer and more effective procedure with similar survival comparable to that of manual anastomosis for the HPCECs patients.
RESUMO
BACKGROUND: Total pharyngo-laryngo-esophagectomy with a reconstruction of gastric pull-up is the most common treatment method for patients with multiple primary upper digestive tract carcinomas, such as hypopharyngeal carcinoma with thoracic esophageal carcinoma. However, neck circumferential defect and tracheoesophageal fistula after gastric necrosis are still challenging problems for surgeons and patients. CASE SUMMARY: This case report presents 2 patients who underwent reconstructive surgeries using 4 local random flaps with a split thickness skin graft in the first case, and 6 local random flaps in the second case to close the circumferential defect and tracheoesophageal fistula after failed gastric pull-up. Both patients achieved good swallowing function and could take solid diet without dysphagia postoperatively. CONCLUSION: For selected patients, local random flaps (with a split thickness skin graft) can be a simple and reliable solution for reconstructing tracheoesophageal fistula or cervical circumferential defect after gastric necrosis, especially when the necrosis extends below the thoracic inlet.
RESUMO
BACKGROUND: Total pharyngolaryngoesophagectomy (TPLE) is associated with major complications and is extremely invasive. In 2011, our institution introduced thoracoscopic esophagectomy in the left hemi-prone position and laparoscopic reconstruction with a gastric tube in patients undergoing TPLE. Herein, we describe the use of this operative method in 26 patients, focusing on the technical aspects of the surgery. MATERIALS AND METHODS: From January 2011 to December 2018, 26 patients underwent minimally invasive TPLE with gastric tube reconstruction in our institute. The thoracoscopic procedure was performed with the patient in the semi-prone position. The patient was then moved to the supine position, and the laparoscopic procedure and pharyngolaryngectomy were started simultaneously. After pharyngolaryngectomy, microvascular anastomoses or free jejunal flap interposition were performed at the site of the gastric tube reconstruction. The data from these 26 patients were retrospectively analyzed. RESULTS: The median age was 66 years, and 3.8% of the patients were female. The Union for International Cancer Control stages of esophageal cancer were 0 (n = 2), I (n = 4), II (n = 7), III (n = 8), and IV (n = 5). Eight patients had concomitant esophageal cancer and head and neck cancer. Reconstruction with only a narrow gastric tube was used in 16 patients, while free jejunal flap interposition was used in 10 patients. The surgical procedures resulted in minimal complications. Postoperative complications of Clavien-Dindo grade ≥1 included anastomotic leakage in two patients and pneumonia in one. CONCLUSION: Thoracoscopic esophagectomy in the left hemi-prone position and laparoscopic reconstruction with a gastric tube in patients undergoing TPLE was safe and effective. The complications were improved via the development of various procedures. Further improvement is necessary before this thoracoscopic approach is established as a standard procedure for TPLE.
RESUMO
For recurrent cases or residual cases following concomitant chemo-radiation therapy (CCRT), salvage surgery is a frequently used treatment options. A swallowing disorder is one of the major complications of CCRT. The purpose of the present study was to evaluate the effect of CCRT on swallowing function in patients who underwent salvage total pharyngo-laryngo-esophagectomy (TPLE), and to evaluate the importance of pharyngeal constriction in patients who underwent TPLE. Between 2008 January and 2014 May, 54 patients were treated with salvage TPLE following CCRT or TPLE at the National Cancer Center Hospital East, Chiba, Japan and were included in the present study. A total of 14 patients underwent salvage TPLE following CCRT for recurrence or residual tumor (the salvage TPLE group), and 40 patients underwent TPLE as initial treatment (the TPLE group). The pharyngeal constriction score and the post-swallowing oropharyngeal residue rate were evaluated, and inadequate velopharyngeal closure was assessed by videofluorography. The pharyngeal constriction score of the salvage TPLE group was poorer than that of the TPLE group (P<0.05). The bolus residue in the oropharynx was significantly larger in the salvage TPLE group than in the TPLE group (P<0.05). With regards to inadequate velopharyngeal closure, there was no significant difference between the TPLE group and the salvage TPLE group (P>0.99). The results of the present study indicate that the swallowing function of patients who undergo salvage TPLE may be affected by CCRT.
