BACKGROUND: Iatrogenic hypoparathyroidism is a common cause of postthyroidectomy hypocalcaemia. It has varying incidence rates after neck surgery in Saudi Arabia, ranging from 0.07% to 65.30%. Hypoparathyroidism can manifest with a spectrum of symptoms, ranging from mild to severe and life-threatening. This study aimed to assess the rate and predictors of iatrogenic hypoparathyroidism after thyroid surgery and its natural course.
METHODS: This retrospective cohort study used a data collection form to extract patient information from the electronic healthcare system (Best-Care) for patients treated from 2017 to 2022. Patients\' demographics, surgical specifics and biochemical profiles were recorded for subsequent analysis.
RESULTS: Among the 343 patients who underwent thyroidectomy, 130 (37.9%) developed hypoparathyroidism, primarily within the first day after surgery. Calcium or vitamin D supplementation before surgery did not significantly influence hypoparathyroidism development. Notably, extensive combined lymph node dissection was significantly associated with postoperative hypoparathyroidism development (p = 0.0004). More patients who underwent central and lateral lymph node dissection (n = 19, 79.17%) developed hypoparathyroidism than patients who underwent central (n = 18, 40.91%) or lateral (n = 8, 38.10%) dissection alone. Permanent hypoparathyroidism was observed in 40 patients (11.66%).
CONCLUSIONS: This study revealed a high incidence of iatrogenic hypoparathyroidism and high rates of permanent hypoparathyroidism. Further research is warranted to better comprehend the risk factors and optimise management strategies for iatrogenic hypoparathyroidism. Overall, our findings emphasise the need for vigilant monitoring and effective management of patients undergoing thyroidectomy and the significance of postoperative replacement therapies.

BACKGROUND: Preoperative malnutrition is a significant factor in patients with pancreatic tumors undergoing pancreaticoduodenectomy. The aim of this study was to assess the association between preoperative malnutrition and delayed discharge within a ten-day timeframe and potential correlations between preoperative malnutrition and postoperative surgical complications.
METHODS: A retrospective cohort study was conducted, recruiting a final sample of 79 patients with benign or malignant cephalic pancreatic tumors from 2015 to 2022. The risk of malnutrition was assessed using the Malnutrition Universal Screening Tool, while length of hospital stay and relevant clinical data were extracted from clinical documentation.
RESULTS: The preoperative malnutrition risk was high in 21.52% of the sample, moderate in 36.71%, and low in 41.77%. Body mass index (BMI) (p = 0.007) and postoperative surgical complications (p < 0.001) were significantly correlated with delayed discharge. No statistically significant differences were found between levels of malnutrition risk and delayed discharge (p = 0.122), or postoperative surgical complications (p = 0.874).
CONCLUSIONS: Postoperative complications and BMI emerge as significant risk factors. The limited sample size may have compromised the collection of homogeneous and significant data. Future studies should evaluate the implementation of personalized nutritional screening tools, nutritional assessment plans, and the involvement of specialized health professionals.

Despite advancement in surgical innovation, C1-C2 fixation remains challenging due to risks of screw malposition and vertebral artery (VA) injuries. Traditional image-based navigation, while useful, often demands that surgeons frequently shift their attention to external monitors, potentially causing distractions. In this article, we introduce a microscope-based augmented reality (AR) navigation system that projects both anatomical information and real-time navigation images directly onto the surgical field. In the present case report, we discuss a 37-year-old female who suffered from os odontoideum with C1-C2 subluxation. Employing AR-assisted navigation, the patient underwent the successful posterior instrumentation of C1-C2. The integrated AR system offers direct visualization, potentially minimizing surgical distractions. In our opinion, as AR technology advances, its adoption in surgical practices and education is anticipated to expand.

Background and Objectives: The role of surgical extraction of the third molar in patients\' sleep quality remains unclear, although it is one of the most common oral surgical procedures. The aim of this study is to assess the changes in patient-reported sleep health outcomes after third molar surgery and to investigate any associations between sleep parameters and post-extraction pain. Materials and Methods: Young adults without known comorbidities who were in need of mandibular third molar surgical extraction were included. All participants completed a sleep diary, the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and Athens Insomnia Scale (AIS) questionnaires, which were used to assess sleep habits, daytime sleepiness, sleep quality and insomnia severity one week before and after extraction. In addition, a visual analog scale was completed postoperatively to assess the perception of pain. Results: Out of 75 patients who completed the study protocol, 32 (42.7%) were males and 43 (57.3%) were females, with a mean age of 24.01 (±3.43) years. Postoperatively, statistically significant higher scores were observed for PSQI [4.85 (±2.32) before vs. 5.39 (±2.75) after, p = 0.041], AIS [5.56 (±3.23) before vs. 6.91 (±4.06) after, p < 0.001] and average weekly number of nocturnal awakenings [2.01 (±3.72) before vs. 4.19 (±5.20) after, p < 0.001] but not for ESS, average weekly sleep duration and average weekly sleep onset latency. Pain perception was increased in patients who slept worse on almost all seven postoperative days, although this did not reach statistical significance. Conclusions: Third molar surgery impacts sleep quality and insomnia severity in the first week after extraction, while there is no effect on daytime sleepiness. The worsening of subjective sleep symptoms after extraction may be associated with an increased perception of pain.

Background and Objectives: This study explored how nefopam, a non-opioid analgesic in a multimodal regimen, impacts postoperative pain, opioid use, and recovery quality in single-port robot-assisted laparoscopic cholecystectomy (RALC) patients with a parietal pain block, addressing challenges in postoperative pain management. Materials and Methods: Forty patients scheduled for elective single-port RALC were enrolled and randomized to receive either nefopam or normal saline intravenously. Parietal pain relief was provided through a rectus sheath block (RSB). Postoperative pain was assessed using a numeric rating scale (NRS) in the right upper quadrant (RUQ) of the abdomen, at the umbilicus, and at the shoulder. Opioid consumption and recovery quality, measured using the QoR-15K questionnaire, were also recorded. Results: The 40 patients had a mean age of 48.3 years and an average body mass index (BMI) of 26.2 kg/m2. There were no significant differences in the pre- or intraoperative variables between groups. Patients receiving nefopam reported significantly lower RUQ pain scores compared to the controls, while the umbilicus and shoulder pain scores were similar. Rescue fentanyl requirements were lower in the nefopam group in both the PACU and ward. The QoR-15K questionnaire scores for nausea and vomiting were better in the nefopam group, but the overall recovery quality scores were comparable between the groups. Conclusions: Nefopam reduces RUQ pain and opioid use post-single-port RALC with a parietal pain block without markedly boosting RSB\'s effect on umbilicus or shoulder pain. It may also better manage postoperative nausea and vomiting, underscoring its role in analgesia strategies for this surgery.

OBJECTIVE: This study aimed to compare complication rates between pylorus-preserving gastrectomy (PPG) and distal gastrectomy (DG) using Korean nationwide survey data and propensity score weighting (PSW). PPG preserves gastric function but may lead to more postoperative complications than DG.
RESULTS: We analyzed 9424 gastric cancer patients who underwent either DG (n = 9183) or PPG (n = 241). PSW balanced variables such as age, sex, TNM stage, comorbidities, ASA score, and surgical approach. Before PSW, 87.8% of DG patients and 87.1% of PPG patients had no complications (p = 0.053). Severe complications (Clavien-Dindo IIIa or higher) were more frequent in PPG (6.6%) than in DG (3.8%) (p = 0.039). After PSW, overall complication rates (p = 0.960) and severe complication rates (p = 0.574) were similar between groups. Incidence rates of anastomotic stricture and leakage were higher in PPG (2.9% and 1.7%) compared to DG (0.6% and 0.5%) (p = 0.001 and 0.036) before PSW, but these differences were not significant after PSW (p = 0.999 and 0.123).
CONCLUSIONS: The PSW-adjusted analysis indicates no significant difference in overall and severe complication rates between PPG and DG in gastric cancer patients.

This study aimed to evaluate the clinical efficacy of percutaneous coaxial large-channel endoscopic lumbar interbody fusion (PCLE-LIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of degenerative lumbar spinal stenosis. The clinical data of patients with degenerative lumbar spinal stenosis who underwent PCLE-LIF (experimental group) and TLIF (control group) surgery from September 2019 to September 2021 were retrospectively analyzed. We collected clinical data and compared the two groups in terms of perioperative parameters, treatment response rate, inflammatory response markers, postoperative complications, postoperative pain, and functional recovery. The results showed that the treatment outcomes in the experimental group were significantly better than those in the control group. Specifically, perioperative parameters and inflammatory response markers in the experimental group were significantly better than those in the control group, with statistically significant differences (P < 0.05). The overall treatment response rate in the experimental group was significantly higher than that in the control group (P < 0.05). Meanwhile, the incidence of postoperative complications in the experimental group was lower than that in the control group, postoperative VAS pain scores and ODI functional scores were lower, and postoperative JOA functional scores were higher than those in the control group, with statistically significant differences (P < 0.05). In conclusion, PCLE-LIF appears to be a promising technique with better clinical outcomes in the treatment of degenerative lumbar spinal stenosis.

BACKGROUND: Improving outcomes after surgery is a major public health research priority for patients, clinicians and the NHS. The greatest burden of perioperative complications, mortality and healthcare costs lies amongst the population of patients aged over 50 years who undergo major non-cardiac surgery. The Volatile vs Total Intravenous Anaesthesia for major non-cardiac surgery (VITAL) trial specifically examines the effect of anaesthetic technique on key patient outcomes: quality of recovery after surgery (quality of recovery after anaesthesia, patient satisfaction and major post-operative complications), survival and patient safety.
METHODS: A multi-centre pragmatic efficient randomised trial with health economic evaluation comparing total intravenous anaesthesia with volatile-based anaesthesia in adults (aged 50 and over) undergoing elective major non-cardiac surgery under general anaesthesia.
CONCLUSIONS: Given the very large number of patients exposed to general anaesthesia every year, even small differences in outcome between the two techniques could result in substantial excess harm. Results from the VITAL trial will ensure patients can benefit from the very safest anaesthesia care, promoting an early return home, reducing healthcare costs and maximising the health benefits of surgical treatments.
BACKGROUND: ISRCTN62903453. September 09, 2021.

OBJECTIVE: The study was performed to compare the mandibular resection guide with a directional guidance slot with the conventional guide regarding three-dimensional positional accuracy.
METHODS: Twenty-six patients with lateral segmental mandibular defects were selected, and randomly allocated into two groups. All defects were managed with preoperative virtual surgical planning. Resection in the test group was conducted using a resection guide with a directional guidance slot, while a conventional resection guide design was utilized in the control group. The linear and angular deviation of the osteotomy planes was analyzed for both groups, along with the accuracy of the insertion of the reconstruction bone block in the resected defect. Data were documented, absolute deviation was calculated, statistical analysis was performed and significance was set at the 5% level.
RESULTS: The cases conducted with a directional guidance templet reported a statistically significant difference when compared to the conventional edge-cutting guide regarding the linear and angular spatial osteotomy plane position (P < 0.001). The defect span analysis reported excellent levels of agreement in both groups (ICC = 1.00, ICC = 0.995), however, the difference between the groups was statistically significant (P < 0.001).
CONCLUSIONS: The study demonstrated the enhanced positional accuracy of the resection plane and reconstruction block placement when a directional slot is incorporated in the computer-generated resection guide.
