Evaluating the surgical trainee ergonomic experience during minimally invasive abdominal surgery (ESTEEMA study).

Minimally invasive abdominal surgery (MAS) can exert a physical cost. Surgical trainees spend years assisting minimally-invasive surgeries, increasing the risk of workplace injury. This prospective questionnaire-based cohort study was conducted amongst general surgery residents in Singapore. Residents assisting major MAS surgery were invited to complete anonymous online survey forms after surgery. The Phase 1 survey assessed physical discomfort scores and risk factors. Intraoperative measures to improve ergonomics were administered and evaluated in Phase 2. During Phase 1 (October 2021 to April 2022), physical discomfort was reported in at least one body part in 82.6% (n = 38) of respondents. Over a third of respondents reported severe discomfort in at least one body part (n = 17, 37.0%). Extremes of height, training seniority, longer surgical duration and operative complexity were significant risk factors for greater physical discomfort. In Phase 2 (October 2022 to February 2023), the overall rate of physical symptoms and severe discomfort improved to 81.3% (n = 52) and 34.4% (n = 22) respectively. The ergonomic measure most found useful was having separate television monitors for the primary surgeon and assistants, followed by intraoperative feedback on television monitor angle or position. Close to 20% of survey respondents felt that surgeon education was likely to improve physical discomfort.

An unusual complication after endoscopic clipping of a gastric ulcer.

A 72-year-old patient presented with malaena secondary to two antral ulcers which were discovered in oesophagogastroduodenoscopy (OGD) after admission. One of the ulcers with a visible vessel was injected with adrenaline and clipped with an OVESCO clip. The patient continued to have coffee ground vomitus on the following day with a drop in haemoglobin level. Repeat OGD showed a large intra-mural haematoma with the clip still in situ and no bleeding from the surface of the ulcer. Patient underwent a coil embolization of the distal gastroduodenal artery (GDA), right gastroepiploic artery and a medial branch of the GDA. Repeat OGD showed that the submucosal haematoma had evacuated, leaving a large, clean-based mucosal defect.

Ectopic parathyroid gland within carotid sheath.

During operative exploration of the neck for parathyroid surgery, the surgeon should always consider possible ectopic locations of the glands and have a reasonable surgical strategy for locating these ectopic glands.

Comparing the Utility and Surgical Outcomes of Harmonic Focus Ultrasonic Scalpel with Ligasure Small Jaw Bipolar Device in Thyroidectomies: A Prospective Randomized Controlled Trial.

BACKGROUND: Ultrasonic or bipolar radiofrequency energy devices are routinely used for dissection and hemostasis during thyroidectomy. We report a single-center, prospective, randomized controlled trial comparing the utility and outcomes of Harmonic Focus, an ultrasonic coagulating shear device (UCSD), versus Ligasure Small Jaw, an electrothermal bipolar vessel sealer (EBVS) in thyroidectomy (NCT01765686). METHODS: Between December 2012 to January 2016, eligible patients were randomized to undergo hemithyroidectomy using either a UCSD or an EBVS. The primary outcome was duration of surgery. Secondary outcomes included blood loss, postoperative complications, ease of device use, ease of device set-up, vocal cord function, postoperative wound drainage, pain score, and adverse events. RESULTS: Of 110 patients assessed for eligibility, 100 were randomly allocated (UCSD: 49 patients; EBVS: 51 patients) and analyzed by intention-to-treat. There were no differences in specimen delivery time, total duration of surgery, wound drainage, and adverse events between the two groups. The UCSD group had a greater proportion of patients with higher postoperative pain scores in the first 72 h (8.1% vs. 2.0%, p = 0.043). Surgeons reported greater ease of use for the UCSD (49% vs. 27%; p = 0.005), while operating room staff favored the EBVS (60% vs. 33%, p = 0.005). CONCLUSIONS: Energy devices are equally effective in reducing thyroidectomy operative times, with no differences in the duration of surgery, drainage, or adverse events. Use of the UCSD was associated with higher postoperative pain scores, but was favored by the surgeons, likely due to the ability to perform fine dissection with the device itself.

Factors driving frequent attendance at emergency departments for patients with head and neck cancer.

BACKGROUND: Patients with head and neck cancer have a higher risk of emergency department (ED) frequent attender (FA). We hypothesized that FAs present with issues different from non-FAs. METHODS: A retrospective cohort study was conducted on Singapore residents with head and neck cancers using de-identified registry merged with electronic medical record data. A competing risk regression analysis was performed to identify factors associated with FA. Aggregated primary diagnoses were compared for patients with and without FA risk factors. RESULTS: Thirteen percent of patients with head and neck cancer were FAs. FA risk factors were Charlson comorbidity index (3+), and socioeconomic status (SES). FAs had a higher proportion of respiratory infections. The spectrum of diagnosis was similar for patients with low and high SES. Current smokers had a greater proportion of respiratory complaints, relative to never smokers. CONCLUSION: Patients with greater comorbidity scores or higher SES were more likely to be FA. FAs were more likely to present with respiratory complaints, likely related to cancer treatment, or smoking status.

Rheumatoid nodule presenting as a buccal submucosal nodule: A rare presentation of a common disease.

BACKGROUND: Rheumatoid nodules are a common manifestation of rheumatoid arthritis but buccal rheumatoid nodules are extremely rare. The purpose of this study was to report a rare case of a rheumatoid buccal nodule and a review of the literature. METHODS AND RESULTS: This case is about a 79-year-old woman with rheumatoid arthritis who was taking methotrexate and hydroxychloroquine, presenting with an enlarging left buccal submucosal mass. An incisional biopsy showed features consistent with that of a rheumatoid nodule. The mass was managed expectantly and the patient was taken off methotrexate with a marked reduction in the size of the nodule. CONCLUSION: Submucosal rheumatoid nodules of the oral cavity are an extremely rare manifestation of rheumatoid arthritis but should be considered in the differential diagnosis in patients with a history of rheumatoid arthritis presenting with submucosal masses. © 2016 Wiley Periodicals, Head Neck 39: E12-E14, 2017.

Outcomes and Prognostic Factors of Radiation-Induced and De Novo Head and Neck Squamous Cell Carcinomas.

OBJECTIVE: We sought to compare clinical outcomes, pathological features, treatment patterns, and survival outcomes between radiation-induced squamous cell carcinoma (RISCC) and de novo SCC (DNSCC) of the head and neck, as well as identify prognostic factors in these patients. STUDY DESIGN: Case-control study. SETTING: Tertiary medical center. SUBJECTS AND METHODS: Retrospective case-control analysis of 34 RISCCs and 136 DNSCCs matched by age at diagnosis, sex, smoking status, and primary tumor site. RESULTS: Median latency of RISCC development was 13 years. Radiation-induced squamous cell carcinomas were more likely to present with node-negative disease than DNSCCs (70.6% vs 42.9%; P = .024). A greater proportion of DNSCCs was treated with curative intent (92.6% vs 79.4%; P = .048) and achieved no residual disease posttreatment (82.2% vs 41.2%; P < .001) compared with RISCCs. Patients with RISCC had poorer overall survival (OS) (median, 1.67 vs 5.03 years; P = .018) and disease-specific survival (DSS) (median, 1.67 vs 8.65 years; P = .001) than those with DNSCC. Among patients who underwent curative treatment with no residual disease after treatment, there were, however, no survival differences between RISCC and DNSCC. CONCLUSION: In our cohort, RISCCs have a poorer prognosis than DNSCCs. However, those able to undergo curative treatment and have no residual disease after treatment have comparable survival outcomes. Locoregional control of these tumors appears paramount in achieving the best outcomes for patients with RISCC.
