[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.

Reconstruction with free jejunal flap in dystrophic epidermolysis bullosa complicated with hypopharyngeal cancer: A case report.

Epidermolysis bullosa (EB) encompasses a range of rare genetic dermatological conditions characterized by mucocutaneous fragility and a predisposition to blister formation, often triggered by minimal trauma. Blisters in the pharynx and esophagus are well-documented, particularly in dystrophic EB (DEB). However, there have been few reports of mucocutaneous squamous cell carcinoma (SCC) in the head and neck region, for which surgery is usually avoided. This report presents the first case of free jejunal flap reconstruction after total pharyngolaryngoesophagectomy for hypopharyngeal cancer in a 57-year-old patient with DEB. The patient with a known diagnosis of DEB had a history of SCC of the left hand and esophageal dilatation for esophageal stricture. PET-CT imaging during examination of systemic metastases associated with the left-hand SCC revealed abnormal accumulation in the hypopharynx, which was confirmed as SCC by biopsy. Total pharyngolaryngoesophagectomy was performed, followed by reconstruction of the defect using a free jejunal flap. A segment of the jejunum, approximately 15 cm in length, was transplanted with multiple vascular pedicles. The patient made an uneventful recovery postoperatively and was able to continue oral intake 15 months later with no complications and no recurrence of SCC in the head and neck region. While cutaneous SCC is common in DEB, extracutaneous SCC is relatively rare. In most previous cases, non-surgical approaches with radiotherapy and chemotherapy were chosen due to skin fragility and multimorbidity. In the present case, vascular fragility and mucosal damage of the intestinal tract were not observed, and routine vascular and enteric anastomoses could be performed, with an uneventful postoperative course. Our findings suggest that highly invasive surgery, including free tissue transplantation such as with a free jejunal flap, can be performed in patients with DEB.

Reconstruction techniques using free jejunal transfer for total pharyngolaryngectomy with total glossectomy.

BACKGROUND: Total pharyngolaryngectomy is sometimes combined with total glossectomy for advanced hypopharyngeal or cervical esophageal cancers involving the tongue base. The optimal reconstruction method for total pharyngolaryngectomy with total glossectomy has not been established due to a considerable diameter mismatch between the floor of mouth and the esophageal stump. This report describes two reconstruction methods using free jejunal transfer. METHODS: Five consecutive patients who underwent total pharyngolaryngectomy with total glossectomy were included, with a mean age of 67.0 (range 55-75) years. Primary tumors included tongue, hypopharyngeal, cervical esophagus, and laryngeal cancers. The mean defect size was 17.0 (16-19) × 6.8 (6-7) cm. Surgical techniques involved either a simple incision or a two-segment method to address the size mismatch between the jejunum and the floor of mouth. In the simple incision method, a longitudinal cut was made to the antimesenteric or paramesenteric border of a jejunum wall to expand the orifice. In the two-segment method, a jejunal graft was separated into two segments to reconstruct the floor of mouth and the cervical esophagus, and these segments were connected with a longitudinal incision to the cervical esophageal segment to form a funnel-shaped conduit. RESULTS: Of the five patients, three underwent the simple incision method and two the two-segment method. Postoperative pharyngoesophagography showed a smooth passage for all patients. Postoperative courses were uneventful except for one flap loss due to arterial thrombosis. Four patients achieved oral feeding, while one became gastric-tube dependent. At a mean follow-up of 22.1 (4-39) months, one patient required tube feeding, two tolerated full liquid, and two consumed a soft diet. CONCLUSIONS: Both the simple incision and two-segment methods achieved satisfactory swallowing function. The choice between these reconstruction methods may depend on the extent of resection of the posterior pharyngeal wall.

Discrete prognostic implication of sarcopenia according to nutritional status in surgically treated patients with hypopharyngeal cancer.

BACKGROUND: Nutritional status and sarcopenia affects the prognosis of head and neck cancers including hypopharyngeal cancer. Hypopharyngeal cancer patients tend to exhibit sarcopenia, which is associated with poor treatment outcomes. This study aims to determine the correlation between nutritional status and sarcopenia, and their prognostic role in surgically treated hypopharyngeal cancer. MATERIALS AND METHODS: Patients who had been diagnosed with squamous cell carcinoma originating from the hypopharynx and underwent surgery between January 2009 and December 2019 were enrolled in this study. The median neutrophil-to-lymphocyte ratio and prognostic nutritional index (PNI) of the cohort were considered the cut-off values. Sarcopenia was evaluated by measuring skeletal muscle index (SMI) at the third lumbar vertebra. Clinical and serological factors predictive of survival outcomes were evaluated. RESULTS: Patients with high PNI showed better 5-year Overall survival (OS) (52.8% vs. 27.2%, p = 0.001) and disease-free survival (DFS) (59.6% vs. 44.6%, p = 0.033) than those with low PNI. Likewise, patients with low SMI showed worse 5-year OS (25.0% vs. 60.9%, p = 0.002) and DFS (42.4% vs. 68.7%, p = 0.034) than patients with high SMI. Among the patients with high PNI, those with sarcopenia displayed significantly worse OS than those with high SMI (78.0% vs. 34.4%, p = 0.049). High PNI with high SMI presented better overall (p = 0.010) and DFS (p = 0.055) than any other group. CONCLUSIONS: Both sarcopenia and PNI were associated with the prognosis of hypopharyngeal cancer. Considering that PNI and sarcopenia indicate the nutritional status, nutritional status may be a significant risk factor. Therefore, nutritional support that ameliorates sarcopenia may improve survival outcomes in surgically treated patients with hypopharyngeal cancer.

Induction chemotherapy followed by transoral laser microsurgery with or without adjuvant therapy for advanced hypopharyngeal cancer patients: A preliminary result.

BACKGROUND: Hypopharyngeal squamous cell carcinoma (HPSCC) has the poorest prognosis among head and neck cancers. Its treatment may significantly affect breathing, speaking, and swallowing. Induction chemotherapy (ICT) followed by transoral laser microsurgery (TLM) could reduce these adverse effects and achieve good outcomes. METHODS: This was a retrospective study of 11 patients with advanced HPSCC. All patients underwent ICT and TLM alongside tailor-made adjuvant therapy based on the pathological features. RESULTS: Adjuvant therapy was done in seven of 11 patients (64%). The 3-year disease-free survival and laryngeal preservation rates were 78% and 91%, respectively. At the last follow-up, 10 of 11 patients (91%) had no tracheostomy or feeding tube. CONCLUSION: ICT followed by TLM is an appropriate treatment for good tumor control in select patients with advanced HPSCC while preserving laryngeal function.

Laryngectomy plus postoperative radio(system)therapy versus primary radio(system) therapy for the treatment of locally advanced laryngeal and hypopharyngeal cancer - results from the University Clinical Cancer Registry Regensburg.

BACKGROUND: There are few adequate randomized clinical trials directly comparing the therapeutic options of primary laryngectomy (pLE) vs. primary radio(system)therapy (pR(S)T) in patients with locally advanced laryngeal and hypopharyngeal carcinoma and thus little clear scientific evidence to decide which patients will benefit most from which procedure. AIMS/OBJECTIVES: Aim was to compare survival between the therapeutic options and to learn from the limitations of this study, especially in the context of improved clinical assessment. MATERIAL AND METHODS: The clinical data of patients treated between January 2010 and February 2022 were obtained from the electronic database of the University Hospital Regensburg. Overall survival (OS) and progression-free survival (PFS) were compared between the treatment groups. RESULTS: The study included 193 patients (pLE n = 68, pR(S)T, n = 125). Median OS was 31.2 months and median PFS was 24.7 months with no significant difference between the treatment groups (p > .050). Patients who did not receive complete treatment as recommended by the tumor conference (n = 47, 24.4%) had a higher risk of death (p = .024). CONCLUSIONS AND SIGNIFICANCE: The results of our study are consistent with the survival data reported in the literature. More detailed systematic data in clinical routine (e.g. relevant comorbidities) are required to ensure guideline-based recommended therapy.

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.

Homolateral Embolic Stroke After Emergency Ligation of the Common Carotid Artery to Stop Heavy Bleeding Caused by Carotid Blowout Syndrome.

Emergency common carotid artery (CCA) ligation for bleeding control during carotid blowout syndrome with consecutive embolic stroke has been reported rarely. The patient is a 70-year-old man, who was suffering from acute profuse bleeding from the left superior thyroid artery into the piriformis sinus, which was not controlled other than by ligation of the left CCA. The cause of the bleeding remained unclear but was suspected to be related to his history of being positive for squamous cell carcinoma of the left hypopharynx with ari and postcricoid infiltration, diagnosed at age 58. Squamous cell carcinoma was treated with local resection, chemotherapy (docetaxel, carboplatin, and cetuximab), and radiotherapy. Neurological examination 4 days after CCA ligation revealed multiple subacute embolic strokes in the territory of the left middle cerebral artery, macroangiopathy of the extra and intracranial cerebral arteries, and hypoplasia of the left vertebral artery. This case demonstrates that carotid blowout syndrome may require CCA ligation when external carotid artery ligation is not possible, and that ligation can be complicated by an asymptomatic embolic stroke.

Mapping the risk factors, pathogens, and antibiotic of pharyngocutaneous fistula in patients after neck open surgery.

PURPOSE: Current literature lacks consensus on risk factors for pharyngocutaneous fistula (PCF), and empirical antibiotic guidelines for PCF are limited. The aim of this study was to reduce the incidence of PCF and improve antibiotic treatment efficacy for patients with PCF after open neck surgery by analyzing their clinical characteristics, pathogenic bacteria, and antibiotic susceptibility. METHODS: This study was a 13-year single-center retrospective cohort study, including 699 patients who underwent open neck surgery for laryngeal and hypopharyngeal cancer. Univariate and multivariate logistic regression analyses were conducted to identify the risk factors associated with the occurrence of PCF after surgery. The microbial species causing PCF were analyzed, and the antibiotic sensitivity of the top three pathogens was assessed. Venn diagrams were used to illustrate the antibiotics that exhibited 100% sensitivity against all three identified pathogens. RESULTS: The incidence of PCF after open neck surgery was 8%. Logistic univariate and multivariate analyses revealed that flap reconstruction (OR = 3.62, 95% CI [2.02-6.52]), history of preoperative radiotherapy (OR = 2.01, 95% CI [1.31-2.73]), significant postoperative bleeding (OR = 1.79, 95% CI [1.11-2.69]), and history of diabetes (OR = 1.34, 95% CI [1.29-2.46]) were significantly associated with PCF occurrence. Among the 38 cases of PCF patients, the top three identified pathogens were Pseudomonas aeruginosa, Escherichia coli, and Enterobacter cloacae. The antibiotics cefepime, meropenem, ticarcillin/clavulanic acid, and cefoperazone/sulbactam showed 100% sensitivity against these top three pathogens. CONCLUSION: Special attention should be given to patients undergoing open neck surgery, especially those with intraoperative flap reconstruction, a history of preoperative radiotherapy, postoperative bleeding, or diabetes. Strengthening monitoring and care is crucial in preventing the occurrence of PCF. According to antibiotic usage guidelines and considering the distribution of pathogens in PCF patients, empirical antibiotic treatment with cefoperazone/sulbactam or ticarcillin/clavulanic acid is recommended prior to obtaining susceptibility test results.

Oncological and functional outcome after laryngectomy for laryngeal and hypopharyngeal cancer: a population-based analysis in Germany from 2001 to 2020.

Prognostic factors for overall survival (OS), percutaneous endoscopic gastrostomy (PEG) dependency, and long-term speech rehabilitation via voice prosthesis (VP) after laryngectomy for laryngeal or hypopharyngeal cancer were investigated in a retrospective population-based study in Thuringia, Germany. A total of 617 patients (68.7% larynx; hypopharynx; 31.3%; 93.7% men; median age 62 years; 66.0% stage IV) from 2001 to 2020 were included. Kaplan-Meier and Cox multivariable regression analyses were performed. 23.7% of patients received a PEG. 74.7% received a VP. Median OS was 131 months. Independent factors for lower OS were stage IV (compared to stage II; hazard ratio [HR] = 3.455; confidence interval [CI] 1.395-8.556) and laryngectomy for a recurrent disease (HR = 1.550; CI 1.078-2.228). Median time to PEG removal was 7 months. Prior partial surgery before laryngectomy showed a tendency for independent association for later PEG removal (HR = 1.959; CI 0.921-4.167). Postoperative aspiration needing treatment was an independent risk factor (HR = 2.679; CI 1.001-7.167) for later definitive VP removal. Laryngectomy continuously plays an important role in a curative daily routine treatment setting of advanced laryngeal or hypopharyngeal cancer in Germany. Long-term dependency on nutrition via PEG is an important issue, whereas use of VP is a stable long-term measure for voice rehabilitation.

[Feasibility and efficacy of pre-management of superior laryngeal artery in endoscopic surgery for hypopharyngeal cancer].

Objective: To explore the feasibility and efficacy for the dissection and ligation of the superior laryngeal artery in endoscopic surgery for hypopharyngeal cancer. Methods: Eight cadaveric heads were selected, and the laryngopharynxes were harvested. The positions of the superior laryngeal arteries entering the larynxes were dissected and observed under endoscopic vision, and their anatomical characteristics were summarized. Twenty-nine patients (all were male, aged 39-74 years old) with hypopharyngeal cancer who underwent transoral endoscopic surgery at the Department of Otorhinolaryngology Head and Neck Surgery of the Second Xiangya Hospital, Central South University from January 2018 to December 2019 were selected, and the patients were randomly divided into two groups by drawing lots, namely, the superior laryngeal artery was actively dissected and occluded during surgery in observation group (n=15) or not in control group (n=14). The differences in surgical time, bleeding volume, postoperative complications, and postoperative disease-free survival rate were compared between the two groups. Statistical analysis was conducted using SPSS 25.0 software. Results: The entry point of the superior laryngeal artery into the larynx was approximately at the level of the superior edge of the thyroid cartilage, and entered the larynx at the posterior one-third of the lateral wall of the pyriform fossa. The superior laryngeal artery might be determined through endoscopic exploration in all patients of observation group. The endoscopic surgery time [(40.00±7.56) minutes] and intraoperative bleeding volume [(24.00±8.28) ml] in the observation group were respectively less than those [(48.57±14.06) minutes and (42.86±15.41) ml] in the control group, and the differences were statistically significant (t=-2.064, P=0.049; t=-4.064, P=0.001). There was no case with postoperative bleeding in the observation group, but with one case of postoperative bleeding in the control group. Total disease free survival rate was 86.2% and there was no significant difference in disease free survival rates between the two groups during a follow-up period of at least 36 months (P=0.986). Conclusion: Dissection of the superior laryngeal artery during endoscopic surgery for hypopharyngeal cancer is feasible, and pre-management and occlusion of the superior laryngeal artery can effectively reduce intraoperative bleeding.
