Does tranexamic acid improve intra-operative visualisation in endoscopic ear surgery? A double-blind, randomised, controlled trial

Safety and Feasibility of Electro-Vaporization of Ligamentum Teres Hepatis in Totally Laparoscopic Gastrectomy

Introduction: The ligamentum teres hepatis may block the field of vision during totally laparoscopic gastrectomy (TLG), especially in patients with obesity. Aim: We used electrocautery to increase the visual field of TLG by shrinking the ligamentum teres hepatis. This procedure is termed electro-vaporization of the ligamentum teres hepatis (EVLTH). Methods: Patients with body mass index (BMI) ≥24 who underwent total laparoscopic distal gastrectomy (TLDG) or total laparoscopic total gastrectomy (TLTG) between January 2020 and December 2023 were retrospectively enrolled. According to the scope of gastrectomy and whether the patients underwent EVLTH, the patients were divided into the TLDG-EVLTH, TLDG-NEVLTH, TLTG-EVLTH, and TLTG-NEVLTH groups. The clinical characteristics, surgical outcomes, and pathological features were compared between the TLDG-EVLTH and TLDG-NEVLTH groups and the TLTG-EVLTH and TLTG-NEVLTH groups. Results: This study included 65 patients who underwent TLDG (EVLTH: NEVLTH = 29:36) and 32 patients who underwent TLTG (EVLTH:NEVLTH = 15:17). There were no significant differences in clinical characteristics, surgical outcomes, and pathological features between the TLDG-EVLTH and TLDG-NEVLTH groups. However, the operation time in the TLTG-EVLTH group was significantly shorter than that in the TLTG-NEVLTH group, and the difference was statistically significant, although differences in other data were not statistically significant. Conclusions: EVLTH is a simple and safe procedure that reduces the operation time of TLTG in patients who are overweight and enhances the field of vision of TLG.

Endoscopic vs microscopic facial nerve decompression for traumatic facial nerve palsy: a randomized controlled trial

PURPOSE

To explore a minimally invasive trans-canal endoscopic facial nerve decompression for traumatic facial nerve palsy and compare it with microscopic facial nerve decompression.

METHODS

35 and 38 patients underwent endoscopic and microscopic facial nerve decompression, respectively, for traumatic facial nerve palsy. Onset of symptoms, type of temporal bone fracture, day of surgical intervention following trauma, ossicular chain status and nature of insult to facial nerve were observed. Time period for recovery (House Brackmann grade ≤ 3), long term recovery rates, pre- and post-operative hearing status, surgical time and post-operative pain were compared between groups.

RESULTS

Maximum patients in endoscopic and microscopic groups (77.1% and 76.3%, respectively) had acute onset of symptoms. 57.1% (20/35) had longitudinal, 17.1% (6/35) had transverse and 25.7% (9/35) had mixed fractures in endoscopic group. In the microscopic group, 57.9% (22/38) had longitudinal, 18.4% (7/38) had transverse and 23.7% (9/38) had mixed fractures. The mean (± S.D.) post-operative air-bone gap in endoscopic and microscopic group were 16.47 ± 4.5 dB and 19.4 ± 5.2 dB, respectively, which was statistically significant. The mean (± S.D.) time period for recovery of endoscopic and microscopic groups were 14.4 ± 5 days and 22.5 ± 7 days, respectively (p value < 0.05). The difference in post-operative pain between the two groups was also statistically significant. The difference in long term recovery rates was not statistically significant (p > 0.05).

CONCLUSIONS

Endoscopic facial nerve decompression results in early recovery, less post-operative pain and better post-operative air-bone gap closure when compared to conventional microscopic technique.

Tranexamic acid administration practice in otolaryngology head & neck surgery; international survey

PURPOSE

Tranexamic acid (TXA) is a potent pro-coagulation drug. Pre-operative, preventive TXA administration and TXA use for active bleeding are established treatments in many medical situations; yet, less is known about its use in otolaryngology head and neck surgery practice. The primary study goals were: MATERIALS AND METHODS: This is an international survey exploring TXA administration strategy. The electronic, anonymous, questionnaire was emailed to all registered Israeli and American Otolaryngology Head and Neck Surgery (OHNS) physicians, investigating TXA administration: RESULTS: Overall, 317 otolaryngologists participated in the study. TXA was administered to 40.5 % of the pediatric population and 50 % of the adult patients when needed. Epistaxis was the most common indication for TXA administration (48-55 %). A small number of otolaryngologists, 4-13 %, recommended preventive TXA for various operations. More surgeons include TXA in their practice and adjusted the dose according to renal function in academic compared to non-academic medical centers and among otolaryngologists practicing in Israel compared to the United States.

CONCLUSIONS

TXA is provided by many otolaryngologists to treat active epistaxis but to a substantially lesser extent as a preventive measure. TXA is given to children and adults, some with substantial comorbidities. Treatment is more common among surgeons working in academic institutes and medical centers in Israel.

Endoscopic Management of Early Stage Middle Ear Paragangliomas - An Australian Case Series

OBJECTIVE

To analyze the outcomes of the endoscopic transcanal approach for removal of early stage middle ear paraganglioma tumors (MEPT).

STUDY DESIGN

Cases series with chart review.

SETTING

Two tertiary Australian Otology centers.

PATIENTS

Adult patients with middle ear paraganglioma tumors treated with transcanal endoscopic approach from 2/2016 to 12/2019. Tumor staging was described using the Modified Fisch-Mattox (MFM). Inclusion criteria included patients with an MFM Class A or B. Exclusion criteria included higher staged or syndromic disease.

INTERVENTION

All tumors were managed with transcanal endoscopic approach.

MAIN OUTCOME MEASURES

Primary outcome measures included disease clearance and hearing measured according to the AAO-HNS guidelines. Secondary outcomes included complications, duration of surgery, and length of stay.

RESULTS

Ten patients underwent totally endoscopic transcanal resection of MEPT (9 female, mean age of 45.5 years, 70% were left sided). Mean tumor size was 6.1 mm (SD 3.4 mm). Five cases (50%) were classified using the MFM system as class A1, two cases were class A2, and three cases were class B1. Three cases required canalplasty for access but were completed entirely endoscopically. Nine of the 10 cases had complete audiometric data. Pre- and postoperative mean air conduction remained stable with a decrease in mean air-bone gap of 2.84 dB. Postoperative complications include one pinhole perforation. There were no facial nerve complications. Mean follow-up period was 10 months (range 4-25 mo) with all cases having resolution of pulsatile tinnitus and no tumor recurrence.

CONCLUSION

The transcanal endoscopic approach for early stage MEPT offers excellent visualization and permits safe and effective removal of disease with the advantages of a minimally invasive technique for patient recovery.
