Complication following gastric pull-up reconstruction for advanced hypopharyngeal or cervical esophageal carcinoma: a 20-year review in a Chinese institute

Objectives

Carcinoma of the hypopharynx and cervical esophagus is a very aggressive cancer with a high incidence of multifocal mucosal involvement and a high incidence of submucosal lymphatic spread. Total pharyngolaryngoesophagectomy and gastric pull-up reconstruction are often the procedures of choice. The aim of this study is to review the complication after gastric pull-up reconstruction in patients with advanced hypopharyngeal or cervical esophageal cancer.

Materials and methods

A total of 208 patients undergoing gastric pull-up reconstruction for squamous cell carcinoma of the hypopharynx invading the cervical esophagus and cervical esophagus at the Affiliated Provincial Hospital of Anhui Medical University in China from 1988 to 2007 were reviewed. Of 208 patients, 124 patients had hypopharyngeal carcinoma invading cervical esophagus; and 84 patients had cervical esophageal carcinoma. The analysis focused on the most common complications and the survival following gastric pull-up reconstruction. This study and its methods have been approved by the institutional review board.

Results

Of the 208 patients, 87 (41.8%) developed some complications, including anastomotic leak (19, 9.1%), pneumonitis (23, 11.1%), pleural effusion (15, 7.2%), wound infection (8, 3.9%), heart failure (4, 1.9%), anastomosis stricture (7, 3.4%), chylous fistula (4, 1.9%), hemothorax (3, 1.4%), hemoperitoneum (2, 1.0%), and burst abdomen (2, 1.0%); there was no gastric necrosis. In our cases, there was no immediate operative mortality; but there were 4 hospital deaths. The average hospital stay was 15 days.

Conclusions

Gastric pull-up reconstruction is a relatively safe and effective method and can be performed with low mortality and acceptable morbidity and result in good quality of lives.

Free flap combined with pectoralis major flap for reconstruction after total laryngopharyngectomy in patients with advanced hypopharyngeal carcinoma

Conclusion: The findings suggest that a pectoralis major flap combined with a free flap is a safe and reliable method of reconstruction after total pharyngolaryngectomy; with this technique, one can help these patients remain disease free, with normal swallowing function, for a relatively acceptable survival duration. Objectives: To determine the functional and oncological outcomes of a combined flap for the extensive defects after total pharyngolaryngectomy in patients with advanced squamous cell carcinoma of the hypopharynx (SCCHP). Method: This study determined the perioperative morbidity and functional and oncologic outcomes of 21 patients with advanced SCCHP who underwent total laryngopharyngectomy and reconstruction using a combination of a pectoralis major flap and a free flap. Results: The free flap and pectoralis major flap were used to reconstruct the defects for all 21 patients. Fourteen patients were reconstructed with jejunal free flaps and pectoralis major flaps; in the remaining seven patients, anterolateral thigh flaps and pectoralis major flaps were used. All the combined flaps worked well, and patients recovered normal swallowing function a mean 19.4 days after surgery. After an overall mean follow-up time of 31.3 months, 30% of patients were still alive at the time of this analysis, with no evidence of disease.

Impact of CAD/CAM mandibular reconstruction on chewing and swallowing function after surgery for locally advanced oral cancer: A retrospective study of 50 cases

ObjectiveComputer-aided design and computer-aided manufacturing (CAD/CAM) techniques are increasingly applied to mandibular reconstruction, but the superiority of this method in oral food intake has not been well established. Considering the extent of mandibular defects, this retrospective study was aimed to clarify the impact of CAD/CAM mandibular reconstruction on chewing and swallowing function after surgery for locally advanced oral cancer.Materials and methodsWe performed a retrospective review of 50 patients who had undergone segmental mandibulectomy with free flap reconstruction for locally advanced oral cancer. The patients’ Functional Oral Intake Scale scores were measured at 3 months after surgery, and possible contributing factors including CAD/CAM mandibular reconstruction and the extent of mandibular defects for oral food intake were subjected to univariate analysis and multivariate logistic regression analysis.ResultsMultivariate logistic regression analysis showed that CAD/CAM mandibular reconstruction was independently associated with good oral intake, whereas both anterior or extensive mandibular resection and glossectomy were also independently associated with poor oral intake after surgery.ConclusionThe present study showed the positive impact of CAD/CAM mandibular reconstruction on chewing and swallowing function after surgery for locally advanced oral cancer for the first time.     

Ileocolic free flap reconstruction,concomitant chemotherapy and radiotherapy and assessment of speech and swallowing function during management of advanced cancer of the larynx and hypopharynx: Preliminary report

Conclusion

The new technique of ileocolic free flap reconstruction provides a better quality of life in terms of swallowing and speech for patients who have undergone laryngopharyngectomy with concomitant chemotherapy and radiotherapy (CCRT).

Objectives

To compare and contrast the swallowing and speech outcomes of patients who underwent total laryngopharyngectomy with ileocolic free flap reconstruction and to analyze the survival rate after surgery and CCRT.

Material and methods

This was a follow-up study of 12 patients with advanced (stages III, IVA and IVB) laryngeal and hypopharyngeal cancer who underwent major surgery, CCRT (with one exception) and ileocolic free flap reconstruction.

Results

All patients were able to tolerate single-stage combined management comprising total laryngopharyngectomy with or without radical neck dissection plus ileocolic free flap reconstruction and postoperative CCRT (with one exception), without immediate morbidity or mortality. Eleven patients were diagnosed with hypopharyngeal cancer and one with laryngeal cancer. The mean interval between surgery and CCRT was 34.1 days. The mean follow-up period was 16.5 months. Four patients died during the follow-up period as a result of local recurrence (n=2), distant metastasis (n=1) and suicide (n=1). One patient was alive with disease despite neck recurrence.     

Palatal mucoperiosteal flap for oro-nasal fistula following maxillectomy for maxillary sinus cancer

ObjectivesThis study aimed to describe the technique and clinical outcomes of using a palatal mucoperiosteal flap for oro-nasal fistula closure following resection of maxillary sinus cancer.MethodsThe study was conducted with the permission of the internal review board of the Japanese Red Cross Wakayama Medical Center. Five consecutive cases from 2016 to 2020 of surgically treated maxillary sinus cancer in which the oro-nasal fistulas were closed using a palatal mucoperiosteal flap were retrospectively reviewed.ResultsFollowing tumor resection, the oro-nasal fistula was closed using a palatal mucoperiosteal flap. Complete separation of the oral and nasal cavities was achieved in four patients. Oral intake was resumed within two weeks in four patients. All the patients were able to eat foods similar to those in the preoperative period. Their postoperative speech function was excellent, with no difficulty in communicating with others.ConclusionIn the selected cases of maxillary sinus cancer, preservation of the palatal mucosa and closure of an oro-nasal fistula using a palatal mucoperiosteal flap was possible with reasonable outcomes for swallowing and speech functions. The use of this local flap is recommended as a minimally invasive procedure that can be performed especially in patients with limited physiological reserves which preclude free flap reconstruction.     

Esophageal reconstruction with larynx preservation using forearm-free flap

Surgery for cervical esophageal malignancy frequently involves comcomitant total laryngectomy carried out because of either oncologic or functional concerns. Though uncommon, preservation of the larynx has, in recent years, been described in patients undergoing cervical esophagectomy with reconstruction of the resulting circumferential esophageal defect achieved using either free jejunal flaps or gastric pullup procedures. The use of tubed-free cutaneous flaps for circumferential cervical esophageal reconstruction, however, has been rarely described in situations where the larynx has been preserved. We describe successful use of a tubed radial forearm-free flap for reconstruction of a circumferential cervical esophageal defect with preservation of the larynx. Use of the radial forearm flap in this situation resulted in minimal donor site-related morbidity, avoided the need for laparotomy and excellent voice and swallowing function were maintained. As such, use of tubed cutaneous free flaps can be considered an option for cervical esophageal reconstruction when the larynx has been preserved.     

Analysis of outcome of free jejunal-autograft for head and neck reconstruction--postoperative complications and functional results of swallowing in 49 cases

We evaluated postoperative results in 49 patients (39 men, 10 women) who underwent pharyngoesophageal reconstruction with free-jejunal autograft following total pharyngolaryngoesophagectomy in the Department of Otolaryngology, Hokkaido University School of Medicine from 1989 to 1997. Evaluation was performed regarding the following points: 1) postoperative complications, 2) factors that determine the functional results of swallowing, 3) relation between forms of jejunal anastomosis and swallowing. The primary malignancy site was hypopharynx (39), cervical esophagus (4), larynx (3), thyroid (2) and trachea (1), Reconstructions were made with free jejunal autograft alone in 45 cases and with free jejunum in combination with gastric pull-up in 4. In patients who underwent reconstruction with jejunum alone, the anastomosis of the jejunum to the pharynx was performed in side-to-end fashion in 22, end-to-end in 18 and rho-shaped in 4. In the 1 remaining case, we used jejunal-patch graft. Postoperative complications including minor or nongraft related, occurred in 24 of 49 (49.0%) patients. Among these, graft-related complications were graft failure in 1 (2.0%), fistula formation in 3 (6.1%) and graft stricture in 2 (4.0%). Re-operations were required in one case of graft failure and 2 of fistula formation. Consequently, the overall graft-survival rate was 98.0% (48/49). Therefore, we considered the method of reconstruction to be a reliable procedure with a high-success rate. The swallowing function after reconstructive surgery was studied in 35 patients who underwent side-to-end (18) and end-to-end (17) anastomosis of the jejunum to the pharynx. We indicated that appropriate tension in the jejunum was the most important factor for adequate swallowing function. The end-to-end group had a higher rate of taking normal diet compared with the side-to-end group. The rate of swallowing dysfunction was only 5.9% (1/17) in the end-to-end group. On the other hand, 4 of 18 (22.2%) cases in the side-to-end group were regarded as having poor swallowing function. As a result we considered the end-to-end proximal jejunal anastomosis to be the more desirable form.     

The infrahyoid myocutaneous flap for reconstruction after oral cancer resection: A retrospective single-surgeon study

ObjectiveTo review our experience with infrahyoid myocutaneous flap in reconstruction after oral cancer resection.MethodsChart reviews were completed for all patients who underwent oral reconstruction with an infrahyoid myocutaneous flap by a single surgeon in the Department of Otolaryngology at Chonburi Cancer Hospital from 2011 to 2017. Characteristics of the patients and postoperative complications were analyzed.ResultsOf the 34 patients in the study, 10 (29.4%) developed partial flap loss and 1 (2.9%) developed total flap loss. All cases of partial flap loss resolved with conservative treatment. Apparent cancer involvement of a cervical lymph node was significantly associated with flap failure (odds ratio: 5.0, 95% CI: 1.03–24.28).ConclusionsThe infrahyoid myocutaneous flap is a fairly reliable reconstruction method. The flap should be performed with caution in cases with gross lymph node involvement.     

Quality of life after segmental mandibulectomy and free flap for mandibular osteonecrosis: Systematic review

ObjectiveReview QOL outcomes among patients undergoing segmental mandibulectomy and bony free flap reconstruction for ONJ.Data sourcesPubMed was searched for MeSH terms “Quality of life,” “Osteonecrosis,” “Osteoradionecrosis,” “Bisphosphonate-associated osteonecrosis of the jaw,” “Free tissue flaps,” and “Mandibular reconstruction.”Review methodsEnglish language studies with QOL outcomes data for patients undergoing free flap reconstruction for advanced ONJ were included. 197 records were initially screened; 18 full texts assessed; 10 full texts included. PRISMA guidelines were followed.ResultsTen studies were included in this systematic review: six retrospective, three retrospective with comparison groups, and one prospective. In studies with comparison groups, ONJ patients have worse self-reported QOL than the general population as well as head and neck cancer patients without ONJ. Nearly all patients with QOL measurements (220/235 patients) had ONJ from prior radiation. Segmental mandibulectomy and bony free flap improved overall QOL in over half of patients, as well as pain associated with ONJ in 70–75 % of patients. Surgery did not improve long-term effects of radiation such as chewing, swallowing, and salivary production. Donor site morbidity rarely affects QOL.ConclusionsOsteonecrosis of the jaw (ONJ) worsens quality-of-life, and advanced disease often requires segmental mandibulectomy and bony free flap reconstruction. Patients and surgeons may expect improvement in some, but not all, domains of patient-reported QOL by the use of segmental mandibulectomy and reconstruction for advanced ONJ.     

Supratracheal laryngectomy: a multi-institutional study

IntroductionSupratracheal laryngectomy has been described as a surgical procedure for glottic or supraglottic cancer extending to the subglottic region and/or involving the cricoarytenoid joint, aiming to preserve laryngeal function (breathing, phonation and swallowing), without diminishing locoregional cancer control. The choice of supracricoid laryngectomy in these cases could result in a high risk of compromised resection margins.ObjectiveTo determine the safety, viability, adequacy of surgical margins and the supratracheal laryngectomy results for intermediate and advanced laryngeal cancer by reviewing the results at three different institutions in Brazil.MethodsThis is a retrospective study that analyzed the charts of 29 patients submitted to supratracheal laryngectomy from October 1997 to June 2017. The type of laryngectomy performed was classified according to the European Laryngological Society classification for horizontal laryngectomies. Early and late results were evaluated. Survival rates (overall, specific, disease-free and total laryngectomy-free survival) were calculated. The mean follow-up time was 44 months.ResultsOf the 29 patients submitted to supratracheal laryngectomy, 25 had no previous treatment. One patient (3.4%) had compromised margins. Four patients (13.8%) had recurrence. Of these, three had local recurrence and one had regional recurrence. Five patients (17.2%) required a total laryngectomy, two due to ruptured pexy and three due to local recurrence. Four of these patients (80%) achieved a successful total procedure. Four patients (13.8%) died, two due to postoperative complications and two due to recurrence. Overall, specific, disease-free and total laryngectomy-free survival at 5 years were, respectively, 82.1%; 88.2%; 83.0% and 80.2%.ConclusionSelected patients with intermediate and advanced laryngeal cancer may benefit from supratracheal laryngectomy, that resulted in total laryngectomy-free survival and specific survival of 80.2% and 88.2%, respectively.

Functional evaluation of mandibular reconstruction with bone free flap. A GETTEC study

ObjectivesTo assess the functional results of oromandibular reconstruction by free bone flap, in terms of swallowing, speech and esthetics.Materials and methodsA transverse multicenter study included 134 patients reconstructed by free bone flap between 1998 and 2016, with more than 6 months’ follow-up, in 9 centers. A standardized questionnaire collected data on patients and treatment. Study endpoints comprised: weight loss, mouth opening, gastrostomy dependence, type of feeding, and DHI score. The impact of patient baseline characteristics on these functional criteria was explored by uni/multivariate analysis.ResultsNinety of the 134 patients had cancer. Fibula flap was mainly used (80%). 94% of reconstructions were primary successes. 71% of patients had pre- or post-operative radiation therapy. 88% had less than 50% lingual resection. 97% recovered oral feeding. 89% had intelligible speech. 86% judged their esthetic appearance as good/average. 9% had dental prosthetic rehabilitation. Radiation therapy and extensive lingual resection significantly impacted swallowing function (P = 0.04 and P = 0.03, respectively). Radiation therapy and oropharyngeal extension significantly increased gastrostomy dependence (P = 0.04 and P = 0.02, respectively).ConclusionOromandibular reconstruction by free bone flap enabled return to oral feeding in most cases. More than 80% of patients were satisfied with their result in terms of speech and esthetics. However, the rate of dental rehabilitation was low and the rate of complications was high.     

Functional outcomes and survival of patients with oral and oropharyngeal cancer after total glossectomy

IntroductionCancer of the oral cavity and oropharynx presents aggressive behavior and its diagnosis is, in most cases, performed in advanced stages. Total glossectomy is a therapeutic option in locally advanced cancer, and the only one in the recurrent or residual disease, after chemoradiotherapy.ObjectiveTo evaluate the clinical-epidemiological profile, postoperative complications, survival rates and functional aspects of patients with oral cavity and oropharynx cancer after total glossectomy.MethodsIt was a retrospective study where 22 patients were included with oral cavity and oropharyngeal cancer after total glossectomy at the Hospital Regional do Vale do Paraíba, em Taubaté, São Paulo.ResultsAll patients were male, with a median age of 57 years, most of tumors are located in the tongue and floor of the mouth and classified as stage IVa. Total glossectomy as initial treatment was performed in 18 and as salvage in four patients. The major pectoralis myocutaneous flap was used for reconstruction in all cases. The main postoperative complication was wound infection and salivary fistula.ConclusionOverall survival was 19% and cancer-specific survival was 30.8% in five years. Eight patients were rehabilitated for exclusive oral feeding without the dependence tracheostomy and enteral tube, all with an overall survival greater than 15 months.     

Ethmoid sinus cancer: Results of treatment with surgery and combined therapy

Objective—Ethmoid sinus cancer is a rare paranasal sinus malignancy. Its characteristics include a low incidence rate, a great variety of histopathological types and multiple treatment modalities. Currently, there remains no definite consensus regarding its optimal management. The aim of this study was to examine the outcome of a population of Asian patients with advanced ethmoid sinus cancers that had been treated with surgery plus combined therapy.

Material and Methods—Between January 1989 and December 2002 inclusive, 19 newly diagnosed patients with ethmoid sinus cancers who had undergone surgical intervention were enrolled, T4 being the principal carcinoma stage (68.4%). All participating cases proved to be node-negative and no evidence of any distant metastasis was detected at the time of diagnosis. The major treatment modality was surgery plus postoperative radiotherapy. All but 2 of the 13 patients with T4 cancer underwent craniofacial resection with pericranial flap reconstruction.

Results—The estimated overall and disease-free survival rates 3 years post-treatment were 49.4% and 26.3%, respectively. Local tumor recurrence was more common than regional recurrence and/or distant metastasis. A total of 5/15 T3–T4 patients (33%) developed a neck metastasis, 3 of whom also suffered a distant metastasis. There was no postoperative mortality for the cases treated with craniofacial resection.

Conclusions—Ethmoid sinus cancer typically demonstrates a propensity for late diagnosis and poor prognosis. This study confirms that craniofacial resection plus combined associated therapy is the optimal approach for the effective management of extensive ethmoid sinus tumors and is associated with an acceptable morbidity rate. More aggressive disease management featuring prophylactic concurrent chemoradiotherapy including neck or elective neck dissection plus chemotherapy should be considered for T3–T4 patients as opposed to T1–T2 patients.     

Retrospective analysis of 659 laryngeal squamous cell carcinoma patients treated with open laryngeal function-preserving operations

Abstract

Background: Open laryngeal function-preserving surgery is a common therapeutic strategy for Chinese laryngeal squamous cell carcinoma (LSCC) patients.

Objectives: To explore the fundamental clinical characteristics and survival prognostic factors of LSCC patients treated with open laryngeal function-preserving operations.

Material and methods: about a total of 659 LSCC patients undergoing open laryngeal function-preserving operations were retrospectively reviewed. Kaplan–Meier method, Log-rank test and Cox regression model were performed in survival analyses.

Results: About 612 patients were glottic cancer, followed by 44 cases in supraglottis and 3 cases in subglottis. The number of patients in stage T1, T2, T3 and T4 was 190, 365, 100 and 4, respectively. Nineteen patients had positive cervical lymph nodes. The 5-year overall survival, disease-free survival and disease-specific survival rates were 90.1, 84.9 and 90.7%, respectively. T stage and second primary tumour were independent factors predicting overall survival, while T stage and pathological differentiation were independent risk factors for tumour recurrence and progression.

Conclusions and significance: Open laryngeal function-preserving surgery is a crucial therapeutic strategy for Chinese patients with early and, in some cases, advanced-stage LSCC. Early diagnosis and therapy and sufficient and safe surgical margins are key to improving the survival rate and reducing the risk of relapse in LSCC patients.
