Tracheoesophageal diversion (TED) can prevent damage to the respiratory system in patients with swallowing disorders and/or repetitive aspiration pneumonia; however, TED may cause the loss of phonation. Our previous study demonstrated that TED with tracheoesophageal puncture (TEP) prevents aspiration while retaining phonation. In this study, we aimed to further evaluate the feeding status and phonation of patients who underwent TED with TEP to verify the reproducibility of this procedure.
Case series study.
We retrospectively reviewed the medical records of 11 patients who underwent TED with TEP for intractable aspiration from February 2017 to August 2019 at Fukuoka Sanno Hospital. We evaluated the preoperative penetration aspiration score (PPAS), daily activities, preoperative and postoperative food intake level scale (FILS) score, nutrition route, maximum phonation time(MPT), and postoperative communication method.
The study population included 10 men and 1 woman (mean age, 66 years; range, 44-81) with a PPAS of 6.8 ± 1.0. The FILS score changed from 2.1 ± 0.5 preoperatively to 7.5 ± 2.0 postoperatively (paired t-test, P < .05), while the MPT changed from 7.9 ± 4.1 to 10.3 ± 4.2 s (paired t-test, P = .9). Preoperatively, a gastric fistula (eight patients [73%]) was the main nutrition route, followed by a gastric tube (two patients [18%]). Postoperatively, the main nutritional route for eight patients (73%) was oral, while the remaining three patients (27%) used the oral route occasionally. All patients maintained laryngeal phonation function, and eight (73%) used only laryngeal phonation for communication.
Patients with intractable aspiration who wish to retain phonatory function should be advised to undergo TED with TEP.

OBJECTIVE: Tracheoesophageal diversion (TED) is an effective therapeutic procedure for intractable aspiration. In this study, we performed TED in cases of intractable aspiration and/or repetitive pneumonia, investigated the main route of nutritional uptake after the procedure, and evaluated the swallowing method using videofluoroscopy. We also evaluated the validity of TED for treating intractable aspiration.
METHODS: We retrospectively reviewed 44 patients (30 male and 14 female patients; median age, 55 years; range 15-85 years) who underwent TED for the treatment of intractable aspiration between January 2008 and December 2017. We examined the route of nutritional uptake before and after the operation and performed videofluoroscopy to detect the swallowing method after the operation.
RESULTS: The percentage of patients with oral intake increased from 21% (9/44) before TED to 56% (25/44) within 1 month after TED (p < 0.01); this percentage included patients with poor preoperative swallowing function. Overall, 60% patients who were able to communicate and mobilize using a wheelchair as well as 92% patients who were able to communicate and mobilize in the supine position were able to consume food orally. We subsequently performed videofluoroscopy in 24 of the 25 patients with oral intake and assessed the passage route of the contrast agent, which was found to move through the laryngeal route in 54% of these patients.
CONCLUSIONS: TED may be suitable for the treatment of intractable aspiration and can improve oral intake, particularly in patients with good mobility and communication ability.

CONCLUSIONS: Tracheoesophageal diversion (TED) and laryngotracheal separation (LTS) can prevent aspiration pneumonia and improve the morbidity of patients with severe motor and intellectual disability (SMID). By improving hospitalization rates and care needs, the quality-of-life can be improved for the patients and their parents.
OBJECTIVE: This study evaluated the clinical outcomes of TED and LTS in patients with intractable aspiration and SMID.
METHODS: This study retrospectively reviewed patients with SMID and intractable aspiration pneumonia who underwent TED or LTS at the institution between January 2008 and January 2015. It assessed the frequency of sputum suctioning, the number of pre-operative and post-operative hospitalizations, the operative time, and complications.
RESULTS: Forty patients were identified during the study period. After surgery, there were significant reductions in the frequency of secretion suctioning (from 165.0 times/day to 33.0 times/day) and the number of hospitalizations because of aspiration pneumonia (from 5.4 times/year to 0.2 times/year). A tracheocutaneous fistula occurred in one (2.5%) patient, and two (5.4%) patients developed tracheoinnominate artery fistulas. In the latter group, the innominate arteries were successfully ligated and endovascular embolization was performed.

OBJECTIVE: Tracheo-innominate artery fistula (TIF) is a rare but life-threatening complication following tracheostomy or tracheoesophageal diversion (TED). Although successful surgical intervention for TIF has been reported, few studies have been performed in patients with severe motor and intellectual disability (SMID). Therefore, we aimed to analyze TIF in patients with SMID to clarify the clinical variables predicting the occurrence and adequate management for lifesaving of TIF.
METHODS: We retrospectively reviewed the records of patients with SMID undergoing surgical tracheostomy and TED between 2006 and 2012 and identified those with TIF. When TIF occurred, we obtained the clinical status and emergency management.
RESULTS: Of 70 patients who underwent tracheostomy or TED during the study period, three patients had TIFs; in one case, TIF was avoided by ligation of the innominate artery before TED. The incidence of TIF in those undergoing tracheostomy and TED was 2.3% and 7.4%, respectively. The interval between tracheostomy and TIF was 14-50 months.
CONCLUSIONS: Patients with SMID may have an increased risk of TIF. Prompt diagnosis and surgical intervention to control the bleeding is the only effective management at present.
