Resuming Oral Feeding in Patients With Oral Squamous Cell Carcinoma With Free Anterolateral Thigh Flap Reconstruction.

BACKGROUND: Quality of life and functional improvement have emerged as important goals for patients with oncologic disease. For patients with head and neck cancer, free anterolateral thigh (ALT) flaps serve as reliable reconstruction and provide functional restoration. Nevertheless, factors affecting the resumption of oral feeding are rarely described. This study aimed to evaluate and compare the functional outcomes of oral feeding for patients with different oncologic defect patterns and reconstructive ALT flap designs. METHODS: We retrospectively reviewed patients with head and neck cancer undergoing oncologic ablation and free ALT reconstruction between January 2016 and April 2018 at National Taiwan University Hospital. Patients were categorized into 2 groups as through-and-through (T&T) and non-through-and-through (non-T&T) according to the defect pattern. We further subgrouped T&T patients into lip resection/lip sparing according to lip involvement. Reconstructive ALT flaps were of 2 designs, folded (F-ALT) and chimeric (C-ALT). Outcomes of oral feeding were analyzed using descriptive statistics, and differences between groups were compared using the Student t test. RESULTS: We identified 233 patients who received oncologic ablation and free ALT flap reconstruction. There was no significant difference in functional recovery between the T&T and non-T&T groups (81.2% vs 73%, P = 0.137). However, among patients who succeeded in resuming oral feeding, lip-sparing patients had better functional recovery in terms of early oral feeding within 6 months and nasogastric tube removal compared with lip-resection patients (100% vs 83.3%, P = 0.001). Moreover, the F-ALT design resulted in a higher success rate in resuming oral feeding compared with the C-ALT design (90.5% vs 54.6%, P = 0.032). CONCLUSIONS: Patients with head and neck cancer with T&T defects were associated with higher rates of secondary flap revision and a trend of delayed oral feeding. In the long term, improved oral feeding outcome with the F-ALT design was observed compared with the C-ALT design in the specific group with T&T defect.

Response of a local hospital to a burn disaster: Contributory factors leading to zero mortality outcomes.

OBJECTIVE: To investigate the outcomes of a local healthcare system in managing a burn mass casualty incident (BMCI). METHODS: Thirty-three victims admitted to the National Taiwan University Hospital within 96h of the explosion were included in the study. Data were recorded on: patient demographics, Baux score, laboratory data, management response, treatment strategies, and outcomes. Case notes from June 27, 2015 to November 2015 were reviewed with a focus on fluid resuscitation, ventilation support, nutrition, infection control, sepsis treatment, and wound closure plan. RESULTS: Female predominance (mean age: 21.7 years) and lower extremity circumferential flame burns were the characteristics of the burn injury. The mean Baux score was 70±18. The mean burn area was 42% of the total body surface area (TBSA). A total of 79% patients arrived at the hospital within 24h of sustaining injuries. Intensive care unit (ICU) admission criteria were modified to accommodate patients with 40% TBSA of burns, facilities were expanded from 4 ICU beds to 18 beds, and new staff was recruited. A total of 36% patients (n=12/33, 62±13 TBSA of burns) required fluid resuscitation. The mean volume of Lactate Ringer administered in the first 24h of burns was 3.34±2.18ml/kg/%TBSA, while the mean volume of fresh frozen plasma administered was 0.60±0.63ml/kg/h. Forty-two percent patients were intubated on the day of admission, and 71% of the intubated patients had inhalation injuries that were confirmed by diagnostic bronchoscopy. The mean intubation period was 17±9 days. The incidence of pulmonary edema was 58% (n=7/12), possibly due to sub-optimal monitoring. Of these, 57% (n=4/7) patients progressed to adult respiratory distress syndrome, but were successfully treated with early strict fluid restriction, systemic antibiotics, ventilation support, and bronchial lavage. A total of 94% patients received grafting. The mean grafted area was 4432.3±3891cm2. Tube feeding was provided to patients with burns >40% TBSA. All patients tolerated gastric tube feeding without conversion to duodenal switch. On admission, all patients received prophylactic antibiotics. Septic shock was noted in 12 patients, but no mortality occurred. The mean hospital stay was 1.5 days per percent burn. CONCLUSIONS: This article highlights the value of precise triage, traffic control, and effective resource allocation in treating a BMCI. Effective supporting systems for facility expansion, staff recruitment, medical supplies and clear-cut treatment strategies for severely burned patients are contributory factors leading to zero mortalities in our series, in addition to young age and minimal inhalation injuries. The need for reevaluation of the safety of cornstarch powder in festival activities is clear.
