Abstract
BACKGROUND Partial or total laryngopharyngectomy defects have traditionally been reconstructed using the radial forearm, anterolateral thigh, or jejunal free flaps. The latissimus dorsi myocutaneous free flap (LDMFF) is an option for high-risk patients with complex laryngopharyngeal ± cutaneous neck defects. METHODS Retrospective single-surgeon case series from 2017 to 2022. Outcomes were assessed at both the back donor site and head and neck. RESULTS Twenty-four patients were identified. Flap survival was 100%. There was 1 (4.2%) pharyngocutaneous fistula and 2 (8.3%) tracheo-esophageal peristomal fistulas. At last follow-up, 17 (71%) were sustaining weight on oral intake, and 7 (29%) were G-tube dependent with 4 of these able to do some type of oral intake. Seven (29.2%) had post-operative stricture/stenosis requiring dilation. There were only minor donor site complications, all managed conservatively. CONCLUSIONS The LDMFF can be a robust reconstructive option, particularly for radiated high-risk patients with complex pharyngeal defects, including skin.

Abstract
BACKGROUND There is a lack of consensus regarding the effectiveness of salivary bypass tubes during total pharyngectomy reconstruction to prevent pharyngocutaneous fistula or pharyngoesophageal stricture. METHODS Our study examined tubed free flap reconstruction outcomes for total pharyngectomy defects over 11 years at a single tertiary referral center. We compared postoperative fistula and stricture rates between two groups: those with salivary bypass tubes inserted during reconstruction and those without. RESULTS Among 36 patients, 26 had radial forearm, and 10 had anterolateral thigh free flap reconstruction. 53% received salivary bypass tubes. However, the tubes did not significantly reduce the relative risks of fistula or stricture. Notably, neck dissection during total pharyngectomy was associated with increased fistula incidence. Minor salivary bypass tube-related complications affected 21% of subjects. CONCLUSION The role of salivary bypass tubes in total pharyngectomy reconstruction remains uncertain.

Abstract
INTRODUCTION The aim of this retrospective study was to assess the efficacy of Salivary Bypass Tube (SBT) for preventing pharyngo-cutaneous fistula (PCF) in a recent cohort of patients who underwent primary and salvage total laryngectomy (TL). METHODS A consecutive series of 133 patients who underwent total laryngectomy between 1997 and 2019 was reviewed. The incidence of PCF was compared between patients who did not receive SBT (nSBT group; n = 55) and those preventively receiving SBT (SBT group; n = 78) in both primary and salvage TL. Risk factors for PCF were evaluated in a univariate and multivariate analyses. RESULTS The overall PCF rate was 30%. Preoperative characteristics were similar between the nSBT and SBT groups, except for older age (p = 0.016), lower preoperative hemoglobin (p = 0.043), and lesser neoadjuvant chemotherapy (p = 0.015) in the SBT group. The rate of PCF the nSBT group, was 41.5%, compared to 21.8% in the SBT group (p = 0.020). In multivariate analysis, only the use of SBT was associated with lower risk of PCF (OR = 0.41 (95% CI 0.19-0.89), p = 0.026). This effect was verified only in the subgroup of patient operated for salvage TL (OR = 0.225; 95% CI 0.09-0.7; p = 0.008). CONCLUSION The use of SBT in our series in salvage TL, appears to be associated with a decreased risk of PCF.

Abstract
Objectives Pharyngocutaneous fistula (PCF) is a troublesome complication after total laryngectomy. The “Fistula zero” project aims to reduce the number of PCF by following a detailed protocol based on three fundamental key points. Materials and Methods The Fistula zero project included 77 patients who underwent total laryngectomy in the period from January 2019 to December 2020. The protocol consisted of three main aspects: the systematic placement of a Har-El salivary bypass tube, the continuous horizontal watertight pharyngeal suture using a barbed suture, onlay insetting of a pedicled flap in pre-treated patients. Results One case of PCF (1.3%) and three small blind fistulas (3.9%) were observed in this series. The mean length of hospitalization was 18 days. Conclusion Pharyngocutaneous fistula (PCF) prolongs hospitalization and delays adjuvant treatments. Thanks to a strict adherence to the protocol, it was possible to reduce PCF rates, avoiding lengthy hospitalization and additional surgical procedures.

Do Salivary Bypass Tubes Reduce the Risk of Pharyngocutaneous Fistula after Laryngopharyngectomy-A Systematic Review and Meta-Analysis. Cancers (Basel) 2021; 13:cancers13112827. [PMID: 34204054 PMCID: PMC8201015 DOI: 10.3390/cancers13112827] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 05/30/2021] [Accepted: 06/02/2021] [Indexed: 01/12/2023] Open
Abstract
Simple Summary Salivary bypass tubes (SBT) have been introduced in order to reduce the risk of pharyngocutaneous fistula (PCF) after laryngectomy with pharynx reconstruction. Although the current literature is rather heterogenous, our meta-analysis demonstrates a favorable effect of SBT insertion on PCF formation in patients after laryngopharyngectomies. Abstract To evaluate the effect of salivary bypass tube (SBT) usage on the occurrence of pharyngocutaneous fistula (PCF) in patients after a laryngopharyngectomy, a total of 20 studies, published between 1988 and 2021, were identified including 2946 patients. We performed a meta-analysis assessing the risk of PCF occurrence in patients after SBT application compared to those without. PCF occurred in 26.8% of cases (669/2496) and SBT was applied in 33.0% of patients (820/2483). There was an overall trend towards lower PCF rates when using SBTs (22.2% vs. 35.3%; p = 0.057). We further selected five studies, comprising 580 patients who underwent laryngopharyngectomies, for meta-analysis showing that application of SBT reduced the risk of PCF formation (OR 0.46; 95% CI 0.18–1.18; p = 0.11). The meta-analysis demonstrates a beneficial effect of SBT insertion on PCF formation in patients after laryngopharyngectomy.

Abstract
BACKGROUND Pharyngocutaneous fistula is a potential life-threatening complication following head and neck surgery. There is only limited evidence about the efficacy of vacuum-assisted closure (VAC) therapy and endoscopic vacuum-assisted closure (EndoVAC) therapy for the treatment of pharyngocutaneous fistulas. METHODS In this article, we report on a consecutive case series of six male patients with pharyngocutaneous fistula treated with a modified outside-in EndoVAC technique. We also present a review of the current related literature. RESULTS EndoVAC therapy alone was successful in five of the six patients (83.3%) with a median duration of EndoVAC therapy of 18.5 days (range: 7 to 32 days) and a median number of EndoVAC sponge changes of 4 (range: 1 to 9 changes). One patient needed additional reconstructive surgery after prior radiochemotherapy and jejunal transfer. No treatment-related complications were observed. CONCLUSION EndoVAC therapy is an easy-to-perform, safe procedure for the treatment of pharyngocutaneous fistulae.

Abstract
Salivary Bypass Tube is an important tool to prevent or treat some complications of laryngeal and hypopharyngeal surgery and its placement may prove difficult. In this article, we propose a new technique to simplify its management by using an Oral/Nasal Tracheal Tube Cuffed-Reinforced that allowed us to reduce operating times, complications related to prolonged general anesthesia, and the traumas on the tissues incurred during the forced positioning of the device with standard techniques.

Abstract
OBJECTIVE To evaluate the difference in pharygocutaneous fistula (PCF) development between pectoralis major flap onlay and interpositional reconstructions after salvage total laryngectomy (STL). DATA SOURCES Medline, Cochrane, Embase, Web of Science, CINAHL, and ClinicalTrials.gov. REVIEW METHODS A systematic review was performed during January 2020. English articles were included that described minor and major PCF rates after STL reconstructed with pectoralis major onlay or interposition. PCFs were classified as major when conservative therapy was unsuccessful and/or revision surgery was needed. Articles describing total laryngopharyngectomies were excluded. Meta-analyses of the resulting data were performed. RESULTS Twenty-four articles met final criteria amassing 1304 patients. Three articles compared onlay with interposition, and 18 compared onlay with primary closure. Pectoralis interposition demonstrated elevated odds ratio (OR) of PCF formation as compared with onlay (OR, 2.34; P < .001). Onlay reconstruction reduced overall (OR, 0.32; P < .001) and major (OR, 0.21; P < .001) PCF development as compared with primary pharyngeal closure alone. Data were insufficient to compare interposition against primary closure. CONCLUSIONS This research shows evidence that pectoralis onlay after STL diminishes the odds of total and major PCF development. Pectoralis interposition reconstruction showed elevated odds of PCF formation as compared with pectoralis onlay.

Abstract
PURPOSE To evaluate the prophylactic, protocolized, and standardized use of a Montgomery tube in preventing pharyngocutaneous fistulas after total laryngectomy and neck dissection. STUDY DESIGN Retrospective cohort study. SETTING Tertiary referral centre. SUBJECT AND METHODS A Montgomery salivary bypass tube was placed in 44 patients undergoing total laryngectomy and neck dissection, observing the percentage of fistula appearance and the time of start of deglutition. Comparison was made with a group of 28 patients prior to the implantation of the protocol in whom the tube was not used. RESULTS There was a statistically significant decrease in the percentage of fistulas and an earlier onset of deglutition in the salivary bypass tube patients compared to those in whom the tube had not been used. CONCLUSION Prophylactic and standardized use of the Montgomery salivary bypass tube in patients undergoing total laryngectomy and neck dissection might decrease the incidence of pharyngocutaneous fistula and improve the course of one that is already established.

Abstract
INTRODUCTION Salvage total laryngectomy (STL) is the most common treatment for recurrent laryngeal cancer after (chemo)-radiotherapy [(C)RT]. In this scenario, a higher rate of local wound complications, such as pharyngo-cutaneous fistula (PCF) and pharyngo-esophageal stenosis (PES), is generally expected. The aim of the present study is to evaluate outcomes using a standardized reconstructive protocol. METHODS Between 2009 and 2019, patients undergoing STL after (C)RT were collected at two referral hospitals with the objective of evaluating surgical outcomes using a standardized reconstructive policy based on the use of fascio-cutaneous free flaps as inlay patch grafts and a long-lasting salivary bypass stent. RESULTS Fifty-five patients (mean age, 66 years; male-to-female ratio, 8:1) were included in the study. Previous treatments were RT in 22 (40%) patients, CRT in 21 (38.2%), and partial laryngeal surgery followed by adjuvant (C)RT in 12 (21.8%). Reconstruction was accomplished by radial forearm and anterolateral thigh free flaps in 16 (29.1%) and 39 (70.9%) patients, respectively. Flap success rate was 98.2%. Concerning postoperative complications, we encountered 3 PCFs (5.4%) and 1 PES (1.8%). CONCLUSION The standardized reconstructive protocol analyzed herein granted significantly lower rates of PCF and PES after STL compared with data available in the literature.
