AI summary — for doctors, generated from the abstract only
In a retrospective study of 102 patients with total hypopharyngeal reconstruction, visceral conduits (gastric pull-up and ileocolonic flaps) led to faster return to a regular diet than fasciocutaneous (ALT) flaps, suggesting the type of tissue used matters more than whether a distal connection point is included.
What was studied
A retrospective cohort study of 102 patients who underwent total hypopharyngeal reconstruction (2015-2025) using one of three techniques—free anterolateral thigh (ALT) fasciocutaneous flap (n=57), gastric pull-up (n=24), or free ileocolonic flap (n=21)—comparing postoperative complications, dietary recovery, and 5-year survival, using multivariable Cox models to analyze time to regular diet.
Key findings
- Early pharyngocutaneous fistulas were most common after ileocolonic flap reconstruction (23.8%), while late fistulas occurred mainly after gastric pull-up (12.5%).
- At 3 years, regular diet was achieved by 63.2% of ALT flap patients, compared with 100% of gastric pull-up and 90.5% of ileocolonic flap patients.
- After adjustment, gastric pull-up (adjusted HR 1.79, 95% CI 1.05-3.07) and ileocolonic flap (adjusted HR 2.00, 95% CI 1.06-3.79) were independently associated with faster dietary recovery than ALT flaps; 5-year survival did not differ significantly among the three groups.
Clinical relevance
The findings suggest that visceral (intestinal-based) reconstructions yield superior dietary recovery compared with fasciocutaneous flaps for total hypopharyngeal defects, and that the type of reconstructive tissue used matters more for functional recovery than whether the surgery includes a distal anastomosis, which may inform reconstructive technique selection for this complex surgery.
Who should care
Limitations
This was a retrospective, non-randomized comparison across three surgical techniques, explicitly rated level of evidence 3 by the authors, so patient or surgeon preference in choosing a technique could have influenced outcomes beyond what adjustment for baseline covariates can fully account for.
For reconstructing the throat after removing the voice box and nearby structures, using intestinal-based tissue led to faster return to normal eating than using thigh-skin-based tissue, suggesting the choice of reconstructive tissue type is more important than the specific surgical connection technique.

Abstract
Objective
Circumferential reconstruction is required for total hypopharyngeal defects to restore swallowing. Reconstructive options differ in conduit biology and anastomotic configuration, particularly the presence of a distal alimentary anastomosis. This study compared postoperative complications, dietary recovery, and survival among three reconstructive strategies.
Methods
This retrospective cohort study included 102 patients who underwent total hypopharyngeal reconstruction between 2015 and 2025 using a free anterolateral thigh (ALT) fasciocutaneous flap (n = 57), gastric pull-up (n = 24), or free ileocolonic flap (n = 21). Postoperative complications, long-term dietary outcomes, and 5-year survival were evaluated. Time to regular diet was analyzed using multivariable Cox proportional hazards models adjusting for age, body mass index, length of hospitalization, and endocrine comorbidities.
Results
Baseline characteristics were similar across groups. Early pharyngocutaneous fistulas were most common in the ileocolonic flap group (23.8%), whereas late fistulas occurred mainly after gastric pull-up reconstruction (12.5%). At 3 years, regular diet was achieved by 63.2% of ALT flap patients, compared with 100% of gastric pull-up and 90.5% of ileocolonic flap patients. After adjustment, gastric pull-up (adjusted HR 1.79; 95% CI, 1.05-3.07) and ileocolonic flap reconstruction (adjusted HR 2.00; 95% CI, 1.06-3.79) were independently associated with faster dietary recovery compared with ALT flaps. Five-year survival did not differ significantly among groups.
Conclusion
Visceral reconstructions yield superior dietary recovery compared with fasciocutaneous flaps for total hypopharyngeal defects. The absence of a distal anastomosis alone did not confer a clear functional benefit, underscoring the importance of conduit biology over anastomotic number.
