Comparison of the Incidence of Postoperative Hypothyroidism in Patients Undergoing Conventional Thyroid Lobectomy and Pyramid- and Isthmus-Preserving Lobectomy.

ABSTRACT: Hypothyroidism is a recognized sequela of conventional thyroid lobectomy. However, there have been no studies on the incidence of hypothyroidism following the preservation of the isthmus and pyramid during lobectomy. Therefore, in the present study, we compared the incidence of hypothyroidism following conventional lobectomy and lobectomy during which the isthmus and pyramidal lobe were preserved. Data for a total of 65 patients collected between September 2018 and April 2019 were reviewed retrospectively. Circulating thyroid-stimulating hormone (TSH) concentration was measured before and after surgery in a group who underwent conventional thyroid lobectomy (n = 29) and in a group in which the isthmus and pyramid were preserved (n = 36). We found no significant difference in TSH concentration between the two groups before surgery, or 3 months or 1 year after surgery. Thus, there might be no difference in the incidence of postoperative hypothyroidism between patients who undergo conventional thyroid lobectomy and those in which the isthmus and pyramid are preserved.

Project description:Perioperative neurocognitive disorder (PND) is a common complication following thoracic surgery that frequently occurs in patients ?65 years. PND includes postoperative cognitive dysfunction (POCD) and postoperative delirium (POD). To investigate whether intravenous dexmedetomidine (DEX) is able to improve neurocognitive function in elderly male patients following thoracoscopic lobectomy, a randomized, double-blinded, placebo-controlled trial was performed at the Affiliated Hospital of Inner Mongolia Medical University (Hohhot, China). Patients aged ?65 years were enrolled and were subjected to thoracic surgery under general anesthesia. A computer-generated randomization sequence was used to randomly assign patients (at a 1:1 ratio) to receive either intravenous DEX (0.5 µg/kg per h, from induction until chest closure) or placebo (intravenous normal saline). The primary endpoint was the result of the Mini-Mental State Examination (MMSE). The secondary endpoints were the results of the Montreal Cognitive Assessment (MoCA) and those obtained with the Confusion Assessment Method (CAM), as well as the incidence of POCD and POD during the first 7 postoperative days. Other observational indexes included sleep quality at night, self-anxiety scale prior to the operation and 7 days following the operation and the visual analogue scale (VAS) score at rest and during movement on the first and third day following the operation. Furthermore, at 6 h following surgery, the MMSE score in the DEX group was significantly higher than that in the saline group. At 6 h and on the first day postoperatively, the MoCA score in the DEX group was significantly higher than that in the saline group. The incidence of POCD and POD in the DEX group was 13.2 and 7.5%, respectively, while that in the saline group was 35.8 and 11.3%, respectively. There was a significant difference in the incidence of POCD between the two groups (P<0.01). In the DEX group, mean sleep quality was increased, whereas the mean VAS was decreased compared with the corresponding values in the saline group. In conclusion, elderly male patients who underwent thoracoscopic lobectomy under continuous infusion of DEX (0.5 µg/kg/h) exhibited a reduced incidence of POCD during the first 7 postoperative days as compared with the placebo group. Furthermore, DEX improved the subjective sleep quality in the first postoperative night, reduced anxiety and alleviated postoperative pain. In addition, it increased the incidence of bradycardia. The present study was registered in the Chinese Clinical Trial Registry (www.chictr.org.cn; registration no. ChiCTR-IPR-17010958).

Project description:BackgroundThis retrospective study was designed to evaluate preoperative pulmonary function test (PFT) results and skeletal muscle mass, represented by the erector spinae muscle (EM), as predictors of postoperative pulmonary complications (PPCs) in older patients undergoing lobectomy for lung cancer.MethodsThe medical records, including preoperative PFT, chest computed tomography (CT) and PPCs, of patients older than 65 years undergoing lobectomy for lung cancer were retrospectively examined at Konkuk University Medical Center from January 2016 to December 2021. The sum of cross-sectional areas (CSAs) of the right and left EMs at the level of the spinous process with the 12th thoracic vertebra was used as the skeletal muscle mass (CSABoth).ResultsData from a total of 197 patients were included in the analyses. In total, 55 patients had PPCs. The preoperative functional vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) showed significantly poorer values and the CSABoth had significantly lower values in patients with than in those without PPCs. The preoperative FVC and FEV1 showed significant positive correlations with CSABoth. Multiple logistic regression analysis identified age, diabetes mellitus (DM), preoperative FVC and CSABoth as risk factors for PPCs. The areas under the curves for FVC and CSABoth were 0.727 (95% CI, 0.650-0.803; P<0.001) and 0.685 (95% CI, 0.608-0.762; P<0.001), respectively. The optimal threshold values of FVC and CSABoth to predict PPCs based on a receiver operating characteristic curve analysis were 2.685 L (sensitivity =64.1% and specificity =61.8%) and 28.47 mm2 (sensitivity =62.0% and specificity =61.5%), respectively.ConclusionsPPCs in older patients undergoing lobectomy for lung cancer were associated with lower preoperative FVC and FEV1 values and a lower skeletal muscle mass. Skeletal muscle mass, represented by the EM, was significantly correlated with the preoperative FVC and FEV1. Therefore, skeletal muscle mass may be useful for the prediction of PPCs in patients undergoing lobectomy for lung cancer.

Project description:ImportanceVessel-sealant devices (VSDs) have been popularized for use in thyroid operations; however, the association of their use with postoperative neck hematoma, a rare but potentially fatal complication, has not been well studied.ObjectiveTo examine the association of VSDs vs conventional hemostasis (CH) in thyroid operations with the development of neck hematoma.Design, setting, and participantsThis retrospective cohort study evaluated 10 903 patients in the Thyroid Procedure-Targeted Database of the National Surgical Quality Improvement Program from January 1, 2016, to December 31, 2017. One-to-one nearest-neighbor propensity score matching was conducted to adjust for differences in baseline covariates, including demographics, comorbidities, indications for thyroid procedure (goiter, Graves disease, malignant and benign thyroid nodule), and several other thyroid-specific characteristics, between the VSD and CH groups.Main outcomes and measuresThe primary outcome was postoperative hematoma requiring intervention with open evacuation, return to the operating room, tracheostomy, additional observation, or extended length of stay. Secondary outcomes include recurrent laryngeal nerve injury, operative duration, and hospital length of stay.ResultsOne-to-one propensity score matching yielded 6522 patients (mean [SD] age, 52 [15] years; 8544 [78.4%] female) with 3261 in each exposure group such that distribution of observed baseline covariates was not different between groups of the same propensity score. Within the matched cohort, CH was associated with higher odds of neck hematoma compared with VSD (odds ratio, 2.33; 95% CI, 1.55-3.49; P < .001), with 34 (1.0%) hematomas in the VSD group and 78 (2.4%) in the CH group. On the basis of this analysis, the number needed to treat with a VSD to prevent 1 postoperative hematoma was 74. Secondary outcomes included longer length of hospital stay (incidence rate ratio, 1.29; 95% CI, 1.23-1.36; P < .001]) in the CH group compared with the VSD group but no difference in the odds of recurrent laryngeal nerve injury (odds ratio, 0.90; 95% CI, 0.73-1.11; P = .32) or operative duration (incidence rate ratio, 0.99; 95% CI, 0.96-1.01; P = .24).Conclusions and relevanceUse of VSDs during thyroid operations was associated with reduced odds of neck hematoma compared with CH techniques without increasing odds of nerve injury. The results suggest that postoperative neck hematoma rates after thyroid surgery may differ based on the hemostasis technique and that these differences should be considered when developing strategies for quality improvement of postoperative outcomes.
