Role of Octreotide in Conservative Management of Chyle Leak Post Neck Dissection in Cases of Head Neck Cancer: A Retrospective Analysis

Chyle leak is a dreadful complication in patients undergoing neck dissections. Octreotide has been used in the management of chyle leak post neck dissections in head and neck cancer patients. Currently there is no consensus and practice guidelines on the same. (1) To study the role of octreotide in early cessation of post neck dissection chyle leak. (2) To study incidence of intra-operative and post-operative CL, its relation to the extent of nodal disease and neck dissection, prior radiotherapy. Retrospective analysis of 16 patients out of 529 neck dissection over a period of 03 years between Jan 2016 and Dec 2019 who developed post-operative chyle leak. All patients who had post-operative chyle leak were administered octreotide. Time taken for chyle leak to stop was primary outcome. Secondary outcomes were duration of hospitalization post-operatively, incidence of intra-operative and post-operative chyle leak, its relation to the extent of nodal disease, prior radiotherapy and type of neck dissection. 59 of 529 neck dissections (11.15%) were noted to have intra-operative chyle leak. 16 of 529 neck dissections (3.02%) developed post-operative chyle leak. On applying chi square test, prior multimodality and N plus neck were found to be significant risk factors in developing postoperative chyle leak. Considering only RT versus no RT in prior multimodality treated group, the difference was insignificant. Onset of chyle leak varied from 1 to 5 post-op day (mean 2.68 days). 15 (93.75%) patients responded to octreotide. Chyle leak resolved between 3 and 10 days (mean 5.18 days) and octreotide was given for 5-12 days (mean-7.18 days). Overall duration of hospitalization ranged from 09 to 18 days (mean 12.18 days). 01 patient (6.25%) had to be re-explored due to high volume leak despite using octreotide. Adverse effects of octreotide were minimal and tolerable. Octreotide is effective in reducing the duration of chyle leak, hospital stay and need for surgical intervention. It may be considered as suitable adjunct to conservative measures in the management for post-operative chyle leak.

Pedicled Flap vs. Free Flap Reconstruction in Head and Neck Cancers: Clinical Outcome Analysis from a Single Surgical Team

Head and neck cancers are one of the leading causes of morbidity and mortality in Indian population. Reconstruction and restoration of function are also of paramount importance in these patients. The aim of this study was to report outcomes for free flaps and pedicle flaps in patients with oral cavity cancers. A retrospective analysis of 628 patients with oral cavity cancers who underwent reconstruction with either free flaps or pedicle flaps during 2014-2020 was done. The median age of the cohort was 49 years. The free flap reconstruction was performed in 481 (76%) and pedicle flap in 147 (24%) patients. Among free and pedicle flaps, 27 (5.6%) and 3 (2.1%) respectively had major flap complications and 25 (5.1%) and 14 (9.9%) respectively had minor complications. CCI score > 4 was associated with higher events (p = 0.02) in free flap group. The outcomes of free flaps are similar in comparison to pedicle flaps in patients with oral cavity cancers. The higher CCI score is significantly associated with increased flap-related complications for the free flap group.

Microvascular reconstruction for head and neck cancers in high risk population: clinical outcomes and complications

INTRODUCTION

Microvascular reconstruction is the gold standard for reconstruction in oral cavity cancers. Age and comorbidities determine the type of reconstruction. We aimed to analyse the impact of high-risk comorbidities on perioperative morbidity.

METHODS

This is a retrospective study of 317 patients undergoing microvascular reconstruction from January 2014 to December 2017. High risk patients were based on age, American Society of Anaesthesiologists (ASA) grade (III/IV) and Charlson comorbidity index (CCI) score >4; overall, 73 out of 317 patients were evaluated.

RESULTS

Median age was 59 years. Five patients (6.8%) had complete flap failures and seven (9.5%) had minor complications (wound breakdown, bleeding, wound dehiscence, partial flap loss). ASA score of IV was significantly associated with morbidity while age >65 years and CCI >4 was not associated. The overall flap success rate was 93.2%.

CONCLUSIONS

A high-risk population has nearly similar outcomes for microvascular reconstruction as a younger age group. High ASA score adversely affects surgery-related outcomes.

Redo Tracheostomy: Our Experience, Problems Encountered and How to Overcome Them

Tracheostomy is a life-saving procedure done electively or most commonly in emergency basis. In patients with diagnosed case of cancer in upper airway tract they usually require tracheostomy at some point of time during their whole treatment procedure. Patients receiving radiotherapy or chemotherapy or combination of these are at high risk of developing post treatment changes in neck anatomy. Redo tracheostomy due to any reasons in such types of patients is a surgical challenge. The purpose of this article is to share our surgical technique in redo tracheostomy. During a period of two years 39 patients with diagnosed cancer in head neck region underwent redo tracheostomy at the hand of the author. Twenty-six patients were had received chemoradiation for their primary cancer and 6 patients were planned for second surgery due to recurrence disease in oral cavity. Reasons for redo tracheostomy are: sixteen patients were post chemoradiation on follow up with accidental expulsion of tube, 17 patients were recurrence/residual disease and 6 patients were plan for second surgery due to recurrence disease. In 9 cases the surgery was started by other doctor and taken over by the author due to profuse bleeding (5 cases) and failure to localised the trachea (4 cases). Among the 39 patients successful redo tracheostomy was possible in all. Mild surgical emphysema was encountered in 3 patients which was not significant. There was no other complication related to tracheostomy till the patients were discharge from the hospital. When redo tracheostomy is required in a post chemoradiation patients maintaining the proper dissection plane and procedure is important to avoid unnecessary complication intraoperatively.

[Radiation-induced head and neck pain: Management with botulinum toxin a injections]

PURPOSE

To report the results of Botulinum Toxin A (BTA) for radiation-induced head and neck pain.

MATERIALS AND METHODS

This single-center retrospective study included all the patients treated at our institution with botulinum toxin A injections for radiation-induced head and neck pain between 2006 and 2017. Pain was evaluated by each patient on a visual analogue scale (VAS) (between 0 and 10) before, and 1 month after the injection.

RESULTS

Sixteen patients were included in this series. The mean value of the pain was 8.5 before and 8 after the first injection. The difference was statistically significant (p<0.01). Major response occurred in 15 patients (VAS≤3 after BTA) and complete response in 11 patients (VAS=0 after BTA).

CONCLUSION

Botulinum toxin is an effective treatment for radiation-induced head and neck pain.
