[Colonic interposition with vascular anastomosis for upper digestive tract reconstruction after surgery for hypopharyngeal cancer with esophageal cancer].

Objective: To investigate the feasibility, safety and effectiveness of colonic interposition with vascular anastomosis in reconstructing the entire esophagus and hypopharynx after resection of hypopharyngeal cancer with esophageal cancer. Methods: We conducted a retrospective analysis of 4 male patients with simultaneous multiple primary cancers of the hypopharynx and esophagus, aged 47 to 58, treated in the Department of Head and Neck Surgery at the Hunan Cancer Hospital from February to August 2019. All cases underwent total hypopharyngectomy and total esophagectomy, of whom, three cases presented with total laryngectomy and one case with larynx preservation. Colonic interposition was performed using the left colic artery as a pedicle, with an average colonic length of 48.5 cm. The colon was elevated through the esophageal bed to the neck, and the branch of the colonic mesenteric artery was anastomosed to one of the neck arteries, including the inferior thyroid artery in one case, the transverse cervical artery in two cases, and the superior thyroid artery in one case, and all venous anastomoses were performed with the internal jugular veins. Results: The postoperative neck and abdominal wounds healed well without anastomotic leakage, and all patients were able to resume a regular oral diet within 21-30 days postoperatively. During the follow-up of 48-52 months, two cases died due to tumor recurrence, while the remaining two cases were disease-free survivals. Conclusion: Colonic interposition with vascular anastomosis is a safe and reliable reconstruction method suitable for repairing long-segment upper digestive tract defects after resection of hypopharyngeal cancer with esophageal cancer.

Diet Outcome in Patients With Hypopharyngeal Defects Repaired With Different Reconstruction Flaps: A Comparative Study.

OBJECTIVES: To assess potential risk factors influencing diet outcomes after reconstruction of subtotal hypopharyngeal defects using free patch- or tube-shaped anterolateral thigh (ALT) fasciocutaneous flaps. STUDY DESIGN: Retrospective cohort study. SETTING: First-level referral hospital. METHODS: Between January 2011 and December 2020, we studied hypopharyngeal cancer patients who underwent the reconstruction of hypopharyngeal defects using free patch- or tube-shaped ALT fasciocutaneous flaps. The choice between patch- or tube-shaped ALT flaps depended on the defect's nature, favoring patch-shaped for subtotal defects and tube-shaped for circumferential defects. A restricted diet was characterized by a history of enterostomy or endoscopic esophageal dilation treatment postreconstruction. We analyzed patients with restricted diets at 1- and 3-year follow-up visits. RESULTS: Ninety-eight patients were enrolled; 39 patch-shaped flaps, and 59 tube-shaped flaps. No significances were noted in demographics, postoperative radiotherapy (RT) or chemotherapy, rates of free flap reoperation/salvage, or complications. However, a significant difference emerged in diet outcomes at the 1-year follow-up (P = .005). The rate of a restricted diet was 6.08 times higher in patients with tube-shaped flaps compared to patch-shaped flaps (95% confidence interval [CI]: 1.95-18.94). Stratifying based on postoperative RT revealed a 5.47 times higher rate of a restricted diet in tube-shaped flap recipients compared to patch-shaped flap recipients (95% CI: 1.44-20.48). No significances were observed in 5-year survival rates. CONCLUSION: Concerning postoperative RT, patch-shaped flaps exhibited a lower incidence of a restricted diet compared to tube-shaped flaps. Preservation of the posterior mucosa may play a crucial role in preventing RT-induced esophageal stricture.

[Clinical application of Visual throat forceps in the removal of hypopharyngeal foreign body].

Objective:To explore the feasibility of using self-made visual throat forceps to remove hypopharyngeal foreign bodies. Methods:The throat forceps were combined with the endoscope and connected to a monitor via a data cable resulting in a visual throat forceps apparatus. This device was utilized to examine and treat the hypopharyngeal foreign bodies. Results:Among 53 patients, foreign bodies were detected in 51,with 48 cases involving hypopharyngeal foreign bodies. All were successfully extracted using the visual throat forceps. Three cases, diagnosed as esophageal foreign bodies by electronic gastroscopy, were treated using the same method. Conclusion:Visual throat forceps can be used to examine the hypopharynx and remove foreign bodies. It has the advantages of simple operation, rapid operation, and high success rate of foreign body removal from the hypopharynx. It is worthy of clinical application.

[Transoral robotic surgery in the management of solitary fibrous tumor at the entrance of the hypolaryngeal esophagus: a case report and literature review].

To explore the clinical diagnosis and treatment experience of isolated fibrotic tumor （SFT） occurring in the larynx, hypopharynx and esophageal inlet with a wide range.The patient, admitted to the Department of Otolaryngology-Head and Neck Surgery of Tangdu Hospital of Air Force Medical University was a female aged at 78 years, who was diagnosed with SFT primarily occured at laryngeal, hypopharynx and esophageal entrance. The clinical data, surgical methods, histopathology characteristics of the patient were analyzed respectively. It's proved that a tumor sized about 3.8 cm×2.8 cm×2.0 cm with slippy surface was found at the entrance of the laryngeal, hypopharynx and esophageal entrance, covering the laryngeal vestibule, glottis and right piriform fossa, which was completely resected by transoral robotic surgery. The postoperative pathological diagnosis was SFT. The patient recovered well after surgery and showed no recurrence within 16-month follow-up. SFT occurring in the larynx, hypopharynx, and esophageal inlet is very rare, and transoral da Vinci robotic surgical resection of the tumor in this area is feasible, and has the advantages of clear field of vision, less bleeding, less trauma, fewer complications, and quicker postoperative recovery.

Fasciocutaneous and jejunal free flaps for circumferential hypopharyngeal defect reconstruction: A 22-year multicenter cohort study.

BACKGROUND: It remains unclear whether a tubed fasciocutaneous or jejunal free flap (FCFF and JFF) is preferable for reconstruction of circumferential pharyngolaryngoesophageal defects. METHODS: All consecutive patients with circumferential pharyngolaryngoesophageal defects reconstructed with an FCFF or JFF between 2000 and 2022 were included. Outcomes of interest were rates of fistulas, strictures, and donor-site complications. RESULTS: In total, 112 patients were included (35 FCFFs and 77 JFFs). Fistula and stricture rates were significantly lower following JFF compared to FCFF reconstructions, with 12% versus 34% (p = 0.008) and 29% versus 49% (p = 0.04), respectively. Severe donor-site complications leading to surgical intervention or ICU admittance only occurred after JFF reconstructions (18%, p = 0.007). CONCLUSIONS: The high fistula and stricture rates in FCFF reconstructions and the rate of severe abdominal complications in JFF reconstructions illustrate inherent procedure-specific advantages and disadvantages. Relative pros and cons should be carefully weighed when tailoring treatments to the individual needs of patients.

Transoral robotic vertical partial laryngectomy (hemilaryngectomy) extended to the hypopharynx.

Locally advanced laryngeal cancers treatment often involves total laryngectomy, which some patients are unwilling to undergo, even if this choice reduces their survival probability. Therefore, the objective of laryngeal oncologic surgery is not only to remove the tumor, but also to preserve the organ and its functions. To overcome these concerns, several partial laryngectomy techniques have been developed. This article describes the surgical technique and a case study of a 64-year-old male patient with locally advanced laryngeal squamous cell carcinoma who underwent vertical partial laryngectomy extending to the subglottis and hypopharynx using transoral robotic surgery (TORS) with a da Vinci Single Port surgical robot. The video and article provide a detailed description of the surgical technique, which resulted in successful tumor removal with excellent oncological and functional outcomes.

Pedicled flaps reconstruction of hypopharynx and laryngeal defects: Successful preservation of laryngeal function in patients with advanced hypopharyngeal cancer.

BACKGROUND: Preserving laryngeal function and reconstructing the hypopharynx in advanced hypopharyngeal cancer pose significant challenges for head and neck surgeons. METHODS: A 48-year-old male patient was diagnosed with advanced hypopharyngeal cancer originating from the left pyriform sinus. The tumor extended into the hypopharynx, left vocal cord, ventricular fold, partial aryepiglottic fold, and a segment of the cervical esophagus. A curative tumor resection was performed, and a well-thought-out strategy was employed for hypopharyngeal repair and laryngeal reconstruction. RESULTS: Following the surgery, the patient demonstrated exceptional flap survival, and the tracheostomy tube was removed at the 6-month mark. No surgery-related complications were observed, and both swallowing and vocal functions exhibited a robust recovery. CONCLUSION: Our reconstruction strategy proves effective in preserving laryngeal function among patients with advanced hypopharyngeal cancer.

Successful endoscopic resection for well-differentiated neuroendocrine tumor, Grade 1, in the hypopharynx.

Well-differentiated neuroendocrine tumor, Grade 1 (NET, G1), in the hypopharynx is extremely rare. A 62-year-old woman was referred to our clinic with a tumor in the postcricoid area. The tumor was diagnosed NET on biopsy and there were no metastatic findings on CT, therefore we performed endoscopic resection. Histologic examination revealed well-differentiated neuroendocrine tumor, Grade 1. This case was an extremely rare and valuable case in which endoscopic images can be observed in detail. Endoscopic resection was performed and successful endoscopic and histological resection was achieved.

Single-Port Robotic Removal of a Submucosal Foreign Body in the Distal Hypopharynx.

In this report, we present a 55-year-old female with cervical stenosis that underwent C5-C7 anterior cervical discectomy and fusion surgery complicated by hardware failure requiring removal. One screw remained after transcervical hardware removal due to operative difficulty with the risk of exposing the hypopharyngeal submucosal space. The retained screw caused the patient significant discomfort and dysphagia prompting a transoral attempt at removal. Using a hypopharynx blade on an oral retractor for access, the single-port surgical robot successfully removed the foreign body from the distal hypopharynx. In this case, a single-port surgical robot expanded access to the inferior hypopharynx. Laryngoscope, 134:588-591, 2024.

Successful surgery with preservation of laryngeal function in a patient with collision primary squamous cell carcinoma and adenoid cystic carcinoma in the hypopharynx and synchronous esophageal carcinoma: A case report.

BACKGROUND: The definition of "collision tumor" is the coexistence of two histologically and morphologically distinct tumors within the same anatomical area without histological admixture. Collision tumors featuring primary squamous cell and adenoid cystic carcinomas of the hypopharynx, combined with synchronous esophageal carcinoma, are very rare. METHODS: We describe a patient with a collision tumor of the hypopharynx and synchronous esophageal carcinoma who underwent partial laryngectomy, with preservation of laryngeal function, and radical esophageal resection featuring esophageal reconstruction using a gastric tube. Surgery was successful. RESULTS: Postoperative radiotherapy was recommended after surgery; the patient exhibited no recurrence or distant metastasis to the 17-month follow-up. CONCLUSION: To the best of our knowledge, this is the first report of collision of primary squamous cell carcinoma and adenoid cystic carcinoma in the hypopharynx and synchronous esophageal carcinoma. We performed appropriate surgery and prescribed postoperative radiotherapy. This preserved laryngeal function.

A designed ladder-shaped stent for the treatment of refractory hypopharyngeal corrosive strictures.

BACKGROUND: The treatment of refractory hypopharyngeal corrosive strictures remains challenging nowadays. OBJECTIVES: To introduce a designed ladder-shaped stent for the treatment of refractory hypopharyngeal corrosive strictures. MATERIAL AND METHODS: Patients with refractory hypopharyngeal corrosive strictures treated in our hospital between 2018 to 2022 were recruited in this study. All the patients had a dysphasia score of 4 and four patients had a tracheostomy preoperatively. A designed ladder-shaped stent was placed in the hypopharyngeal area after laser treatment to maintain the opening. This stent was kept for 3-6 months. All the patients were followed-up for at least 6 months after stent removal. RESULTS: Six patients were recruited including two males, three females and one girl. All the patients were tolerable with the stent. There were no immediate or long-term complications. Patients were able to swallow a soft diet after the procedure. No tracheostomy was needed. CONCLUSION: This use of a ladder-shaped stent is helpful in the treatment of hypopharyngeal strictures after laser treatment.

Delayed pathological finding of a small fish bone causing a purulent cyst in the pharynx: a case report.

We describe the case of a patient who swallowed a small fish bone and felt it lodge in her pharynx, but failed to seek medical attention in a timely manner. One week later, no foreign body was found in the hypopharynx or larynx, but a small purulent cyst was present in the epiglottic vallecula. A computed tomography scan showed a high-density area on the lingual surface of the epiglottis, which was considered to represent an embedded fish bone. A week later, the patient's discomfort had subsided, and flexible videoendoscopy showed that the purulent cyst in the epiglottic vallecula had disappeared. We surmise that the purulent cyst had ruptured spontaneously and the foreign body had been discharged. This represents an example of how an impacted small foreign body may be spontaneously discharged from the body.

Single-Port Versus Multiport da Vinci System for Transoral Robotic Surgery of Hypopharyngeal and Laryngeal Carcinoma.

OBJECTIVE: Da Vinci single port (SP) has been recently approved for transoral robotic surgery (TORS). Its characteristics make it particularly feasible for laryngeal and hypopharyngeal surgery. We report our experience comparing intra- and postoperative outcomes, technical advantages, and shortcomings of transoral laryngeal and hypopharyngeal resections performed with the da Vinci SP and the da Vinci Si/Xi systems. STUDY DESIGN: Retrospective database review. SETTING: Single academic tertiary care hospital. METHODS: Subjects included adult patients with laryngeal and hypopharyngeal carcinoma who underwent TORS between 2008 and 2022. The SP and multiport (MP) systems were compared in terms of intraoperative times, short-term postoperative outcomes, and TORS-related complications after a propensity score matching. RESULTS: A total of 185 patients were enrolled (56 SP vs 129 MP patients), and a cohort of 112 patients was analyzed after matching. The docking time was reduced in the SP group (8.84 ± 4.67 vs 6.45 ± 3.11 minutes; p = .003), as well as console time (53.91 ± 29.38 vs 42.70 ± 13.72 minutes; p = .035). Positive margins were more frequent in the MP group (52% vs 43%; p = .34). The mean decannulation time was 1.86 days longer in the SP group (p = .046). No significant differences emerged from the analysis of the duration of hospitalization, enteral feeding, and TORS-related complications. CONCLUSION: SP safety profile is comparable to that of previous models, while it showed advantages in terms of reduced docking times. Console times were also shortened due to improved maneuverability and field visualization.
