Neck dissection for treatment of supraglottic carcinoma associated with deep-seated intermuscular lipoma in the neck: A case report.

Lipomas are superficial tumors that occur primarily in the subcutaneous region and very rarely occur deeply within or between the muscle layers. No reports to date have described cervical lipomas in patients with head and neck cancer who underwent neck dissection. We herein report a case involving a 72-year-old woman with supraglottic carcinoma complicated by a cervical lipoma who underwent simultaneous neck dissection and lipoma removal. The lipoma was a deep-seated intermuscular lipoma arising in the longus cervicis muscle. We initially considered that the lipoma would be removed en bloc with neck dissection, but the imaging findings clearly indicated that the tumor was located more deeply than the prevertebral layer of the deep cervical fascia and outside the range of neck dissection. The lipoma was removed by incision of the prevertebral fascial layer following neck dissection, and no complications occurred.

Efficacy of an enhanced recovery after surgery pathway to manage pain, nausea and vomiting after head and neck surgeries with free tissue transfer reconstruction.

BACKGROUND: Pain and post-operative nausea and vomiting are the main factors that impair the quality of recovery after surgery. Very few reports have analyzed patient-reported outcomes to investigate the efficacy of an enhanced recovery after surgery protocol to alleviate these symptoms after head and neck surgeries with free tissue transfer reconstruction. METHODS: We investigated post-operative pain and post-operative nausea and vomiting in 47 patients who underwent head and neck surgeries with free tissue transfer reconstruction with enhanced recovery after surgery support between February 2021 and August 2022. Patient-reported outcomes were assessed using the visual analog scale and Japanese version of the Quality of Recovery-40. RESULTS: Significant increases in the mean visual analog scale scores for pain and post-operative nausea and vomiting were observed only on post-operative Day 1 compared with preoperative values (pain: 3.19 ± 2.78 vs. 1.96 ± 2.42, P = 0.0408; post-operative nausea and vomiting: 1.52 ± 2.09 vs. 0.54 ± 1.37, P = 0.0194). From post-operative Day 2, there were no significant differences between the pre- and post-operative visual analog scale scores, and no significant increases in the incidences of moderate or severe pain and post-operative nausea and vomiting compared with preoperatively. The Japanese version of the Quality of Recovery-40 score for post-operative pain showed no significant deterioration compared with preoperatively, while the Japanese version of the Quality of Recovery-40 score for post-operative nausea and vomiting showed significant deterioration compared with the preoperative value on post-operative Days 2, 4 and 7. CONCLUSIONS: The visual analog scale and Japanese version of the Quality of Recovery-40 scores for post-operative pain and visual analog scale score for post-operative nausea and vomiting suggested that the enhanced recovery after surgery strategy favorably controlled pain and post-operative nausea and vomiting after head and neck surgeries with free tissue transfer reconstruction. However, as the post-operative Japanese version of the Quality of Recovery-40 score for post-operative nausea and vomiting was lower than the preoperative value, there is still a need for further improvement of the enhanced recovery after surgery pathway.

Postoperative serum interleukin-6 level as a risk factor for development of hyperactive delirium with agitation after head and neck surgery with free tissue transfer reconstruction.

OBJECTIVE: Occurrence of hyperactive postoperative delirium (POD) with agitation after head and neck surgery with free tissue transfer reconstruction (HNS-FTTR) is associated with the risk of life-threatening complications. The relationships between occurrence of hyperactive POD after HNS-FTTR and inflammatory markers reflecting the surgical stress response, represented by postoperative interleukin-6 levels, are not fully understood. METHODS: A retrospective study was conducted on 221 consecutive patients who underwent HNS-FTTR at our department between September 2016 and December 2021. Potential risk factors for POD were examined, including age, operation time, intraoperative blood loss, and postoperative serum levels of blood parameters such as interleukin-6, C-reactive protein, and neutrophil-to-lymphocyte ratio. RESULTS: Hyperactive POD with agitation was observed in 54 subjects (24.4%). The postoperative hospital stay in the POD group was significantly longer than that in the non-POD group (median: 32.5 days vs. 28 days; p=0.0129). Multivariate logistic regression analysis identified age (in years) (odds ratio: 1.102; p<0.0001), operation time (min) (odds ratio: 1.004; p=0.0359), and postoperative serum interleukin-6 level (pg/mL) (odds ratio: 1.005; p=0.0384) as significant risk factors for development of POD. In a receiver operating characteristic curve and area under the curve analysis, the cut-off value for postoperative serum interleukin-6 level to predict POD development was 82.5 pg/mL. The postoperative serum interleukin-6 ≥82.5 pg/mL group developed hyperactive POD with agitation significantly more often than the postoperative serum IL-6 <82.5 pg/mL group (odds ratio: 4.400; p<0.0001). The postoperative serum IL-6 ≥82.5 pg/mL group also had significantly longer postoperative hospital stay (41.58 ± 33.42 days vs. 31.73 ± 22.89 days; p=0.0151), older age (68.60 ± 9.99 years vs. 64.30 ± 12.58 years; p=0.0054), and longer operation time (625.4 ± 114.05 min vs. 575.5 ± 98.73 min; p=0.0009) than the postoperative serum IL-6 <82.5 pg/mL group. CONCLUSION: Postoperative serum interleukin-6 level, as well as age and operation time, were identified as significant independent risk factors for development of hyperactive POD with agitation after HNS-FTTR. Inflammation is a potential target for the prevention and treatment of POD after HNS-FTTR.

Preoperative serum interleukin-6 level in head and neck cancer reflects systemic inflammatory response and is a predictor of postoperative prognosis.

BACKGROUND: The outcome of head and neck cancer has improved in recent years but survival is not yet satisfactory. Interleukin (IL)-6 is a representative inflammatory cytokine and inducer of systemic inflammatory response. It is not known whether preoperative serum level of IL-6 is a prognostic factor in head and neck cancer surgery. METHODS: We studied 181 consecutive patients who underwent head and neck surgery with free tissue transfer reconstruction (HNS-FTTR) between September 2016 and December 2020. Whether preoperative serum IL-6 level was a prognostic risk factor was retrospectively investigated by univariate and multivariate analyses. We also investigated the association between preoperative IL-6 level and representative systemic inflammatory response markers. RESULTS: The preoperative IL-6 ≥ 8 pg/mL group had a significantly worse prognosis than the preoperative IL-6 < 8 pg/mL group (overall survival [OS]: hazard ratio [HR] 3.098, P = 0.0006; disease-specific survival [DSS]: HR 3.335, P = 0.0008). In multivariate analysis, IL-6 ≥ 8 pg/mL and age ≥ 70 years were independent poor prognostic factors for OS (HR 1.860, P = 0.0435 and HR 1.883, P = 0.0233, respectively). The only independent poor prognostic factor for DSS was IL-6 ≥ 8 pg/mL (HR 2.052, P = 0.0329). Serum albumin was significantly lower and serum C-reactive protein and neutrophil-to-lymphocyte ratio were significantly higher in the IL-6 ≥ 8 pg/mL group than in the IL-6 < 8 pg/mL group (all P < 0.0001). CONCLUSIONS: Preoperative serum IL-6 level is an independent poor prognostic factor for both OS and DSS after HNS-FTTR, reflecting the degree of preoperative systemic inflammatory response.

Shoulder function after neck dissection: Assessment via a shoulder-specific quality-of-life questionnaire and active shoulder abduction.

OBJECTIVE: Neck dissection results in a high probability of postoperative shoulder functional impairment, even when the spinal accessory nerve is preserved. Therefore, surgeons must inform patients about the expected functional and qualitative recovery of shoulder function after surgery. METHODS: The present study included a prospective cohort of 66 patients (85 neck dissection sides) who underwent neck dissection between December 2015 and July 2017 at a single institution. The active shoulder abduction angles of the affected side and the patient-reported shoulder-specific quality-of-life recovery score of the Western Ontario Rotator Cuff (WORC) questionnaire were examined at 1, 3, 6, 9, and 12 months postoperatively. Additionally, the association between these outcomes and risk factors for shoulder impairment were investigated. RESULTS: The average active shoulder abduction angles were significantly improved at 3 and 6 months postoperatively compared with 1 month postoperatively (96.5 ± 4.3° at 1 month versus 110.1 ± 4.7° at 3 months, p = 0.035, and versus 142.0 ± 4.6° at 6 months, p < 0.0001). The proportion of patients who were unable to abduct their shoulders by 150° or more was significantly lower at 6 months postoperatively (41.5%) compared with 1 month postoperatively (82.4%, p < 0.0001). The WORC score significantly improved from 60.4 ± 2.4% at 1 month postoperatively to 67.9 ± 2.6% at 6 months postoperatively (p = 0.036). Multivariate analysis revealed that postoperative radiotherapy was a significant risk factor for shoulder impairment at 3 and 6 months postoperatively (p = 0.003 and p = 0.027, respectively), and that level V dissection and head and neck irradiation were significant risk factors for a worse shoulder outcome at 6 and 9 months postoperatively (respective p values for level V dissection and head and neck irradiation were p = 0.049 and p = 0.030 at 6 months postoperatively, and p = 0.016 and p = 0.013 at 9 months postoperatively). CONCLUSION: Satisfactory functional and qualitative recovery of shoulder function was achieved at 6 months after neck dissection. Postoperative radiotherapy was a predictor of poor shoulder function in the early postoperative period; both level V dissection and head and neck irradiation were predictors of poor shoulder function at 6 and 9 months after neck dissection.

Enhanced recovery after surgery program involving preoperative dexamethasone administration for head and neck surgery with free tissue transfer reconstruction: Single-center prospective observational study.

BACKGROUND: There are few reports on Enhanced Recovery After Surgery (ERAS)-based perioperative management following head and neck surgery with free tissue transfer reconstruction (HNS-FTTR). Here, we prospectively evaluated our ERAS program involving preoperative glucocorticoid administration in HNS-FTTR. METHODS: This prospective study included 60 patients who underwent HNS-FTTR at the Miyagi Cancer Center from June 2017 to December 2018. Their treatment plan included receiving perioperative management in accordance with our head and neck ERAS program. Major outcomes of hospitalization periods, early mobilization, early enteral nutrition, and patient satisfaction were assessed, and blood date and vital signs were compared with control patients who underwent HNS-FTTR from January 2014 to September 2016 at our institution before ERAS was implemented. RESULTS: The duration of hospital stay and the duration until completion of the discharge criteria was a median of 25 days and 17 days, respectively. Early mobilization was achieved in 86.0% of the patients at postoperative-day (POD)1 and 96.5% at POD2. Enteral nutrition was started in 80.1% at POD1 and 100% at POD2. Postoperative pain was controlled at mean VAS scores of 1.51-3.13. Clavien-Dindo grade II or higher postoperative complications were evident in 27.6% of the patients. The mean QOR40 score was 179.6 preoperatively, 146.1 at POD3, and 167.8 at POD7. Compared with the control group, there were significantly lower C-reactive protein levels, higher albumin levels, a lower body temperature, a lower neutrophil-to-lymphocyte ratio, less body weight fluctuation, and fewer incidences of decreased blood pressure in the ERAS group. CONCLUSION: Patients who underwent HNS-FTTR with ERAS-based perioperative management achieved early mobilization, early enteral nutrition, favorable pain control, remarkable recovery of patient satisfaction at POD7, and there was evidence of better hemodynamic stability and less inflammatory response compared with control patients.

Preoperative prognostic nutritional index as a method to predict postoperative complications after major head and neck surgery with free tissue transfer reconstruction.

BACKGROUND: Head and neck (H&N) cancer patients are often malnourished and have diminished immunity. H&N surgery with free tissue transfer reconstruction (HNS-FTTR) is associated with a relatively high incidence of postoperative complications. METHODS: Associations between possible risk factors and postoperative Clavien-Dindo (C-D) grades ≥ II and ≥ IIIa wound healing- or infection-related complications, postoperative overall complications and prolonged hospital stay were investigated in 188 patients who underwent HNS-FTTR during 2014-2018. The preoperative prognostic nutritional index (PNI) was calculated using the serum albumin level and total lymphocyte count. RESULTS: C-D ≥ II and ≥ IIIa complications were seen in 66 (35.1%) and 37 (19.7%) patients, respectively. Multivariate analysis showed that (i) previous irradiation was significantly associated with C-D ≥ II wound healing- or infection-related complications and prolonged hospital stays [odds ratio (OR) 3.096 and 3.328; P = 0.007 and 0.008, respectively]; and (ii) operation time of ≥9 h 20 min was a significant risk factor for C-D ≥ IIIa wound healing- or infection-related complications, and C-D ≥ IIIa overall complications (OR 2.987 and 2.257; P = 0.021 and 0.047, respectively). (3) Only preoperative PNI ≤ 40 was associated with all occurrences of C-D ≥ II and ≥ IIIa wound healing- or infection-related complications, C-D ≥ II and ≥ IIIa overall complications, and prolonged hospital stays (OR 3.078, 2.918, 2.627, 3.132 and 3.116; P = 0.020, 0.046, 0.036, 0.023 and 0.025, respectively). CONCLUSIONS: PNI, easily calculated, was the lone risk factor significantly predicting all C-D ≥ II and ≥ IIIa postoperative wound healing- or infection-related complications, C-D ≥ II and ≥ IIIa postoperative overall complications and prolonged hospital stay after HNS-FTTR.

Enhanced Recovery After Surgery program with dexamethasone administration for major head and neck surgery with free tissue transfer reconstruction: initial institutional experience.

OBJECTIVES: Enhanced Recovery After Surgery (ERAS) protocols promote recovery after various invasive surgeries. Likewise, preoperative glucocorticoid administration can reduce complications after some surgeries. However, the effects of ERAS protocols and glucocorticoid administration in patients undergoing major surgery for head and neck cancer have not been well described. The aim of this study was to evaluate the effect of an ERAS protocol with preoperative glucocorticoid administration in major surgery for head and neck cancer. METHODS: This retrospective study included 28 patients who underwent major head and neck surgery with free tissue transfer reconstruction at our institution from September 2016 to May 2017, after implementation of an ERAS protocol with preoperative glucocorticoid administration. Outcomes in that group were compared with those in a control group that underwent surgery from January 2015 to September 2016, before implementation of the protocol. RESULTS: Analysis revealed significantly less body weight fluctuation, lower C-reactive protein levels, higher albumin levels, and lower body temperature in the ERAS group than in the control group postoperatively. CONCLUSIONS: Patients undergoing major surgery for head and neck cancer who were treated with the ERAS protocol and preoperative glucocorticoid administration had evidence of better hemodynamic stability and less inflammatory response than control patients.
