Numerical Analyses of Idealized Total Cavopulmonary Connection Physiologies with Single and Bilateral Superior Vena Cava Assisted by an Axial Blood Pump

Our study evaluated the hemodynamic performance of an axial flow blood pump surgically implanted in idealized total cavopulmonary connection(TCPC)models.This blood pump was designed to augment pressure from the inferior vena cava(IVC)to the pulmonary circulation.Two Fontan procedures with single and bilateral superior vena cava(SVC)were compared to fit the mechanical supported TCPC physiologies.Computational fluid dynamics(CFD)analyses of two Pump-TCPC models were performed in the analyses.Pressure-flow characteristics,energy efficiency,fluid streamlines,hemolysis and thrombosis analyses were implemented.Numerical simulations indicate that the pump produces pressure generations of 1 mm to 24 mm Hg for rotational speeds ranging from 2000 RPM to 5000 RPM and flow rates of 2 LPM to 4 LPM.Two surgical models incorporated with the pump were found to be insignificant in pressure augmentation and energy boost.The risk assessment of blood trauma and thrombosis generation was evaluated representatively through blood damage index(BDI),particle resident time(PRT)and relative resistant time(RRT).The hemolysis and thrombosis analyses declare the advantage of the pump supported bilateral SVC surgical scheme in balancing flow distribution and reducing the risk of endothelial cell destruction and trauma generation.

Patient-reported dissatisfaction following second side in staged bilateral total knee arthroplasty: A systematic review

BACKGROUND Around one third of patients who undergo total knee arthroplasty(TKA)will eventually have the contralateral knee replaced.Overall patient satisfaction after staged bilateral total knee arthroplasty procedures performed on different days is reportedly similar to unilateral TKA.Nevertheless,in our anecdotal experience patients often report less satisfying outcomes following the second side.A cursory review of available literature tended to confirm that observation.We sought therefore to consolidate all of the available data on this issue to further investigate this phenomenon.AIM To consolidate available published data revealing satisfaction scores among patients following staged bilateral TKA,and to evaluate the phenomenon of less satisfying results following TKA2.METHODS A systematic review of available literature reporting on satisfaction with TKA1 and TKA2 after staged bilateral knee arthroplasty was undertaken using PubMed,Google Scholar,and Embase.From 427 records,five full-length articles met criteria for inclusion in the meta-analysis.The data were then extracted and assessed on the basis of the Reference Citation Analysis(https://www.referencecitationanalysis.com/).RESULTS A total of 1889 patients with an average age of 68(range:38–92)underwent staged bilateral TKA with outcomes reported at 1 year following each TKA with a mean 21.9 mo between surgeries(range:2 d to 14.5 years).Overall satisfaction with both knees was 83.70%(1581)and dissatisfaction with both knees was 2.75%(52).In the remaining 13.56%(256)who were dissatisfied with one side,61.0%were dissatisfied with TKA2,and 39.0%were dissatisfied with TKA1.Patient-reported outcome scores for TKA2 were frequently lower than TKA1 even in patients reporting overall satisfaction with both knees.CONCLUSION At 1-year follow-up,there was a 50%greater risk of dissatisfaction with TKA2 among the 13.56%of patients reporting dissatisfaction in one knee after staged bilateral TKA.Whether the interval between procedures or long-term follow-up changes these results requires further investigation.

Clinical Use of a Drain Incision Placed Below and Bilaterial to Near Total Thyroidectomy Incision

Objective： To design a new draining method for near total thyroidectomy at the lower two sides of the neck. Methods： Near total thyroidectomies in 63 cases were performed with new drain incisions at the lower two sides of the neck between December 1998 and July 2004. Results： All the draining operative procedures were performed smoothly, and all produced cosmetic scars were effective. The mean amount drained was 38 ml （minimum 10 ml, maximum 120 ml） and no patient developed wound infection. Conclusion： The drain incision for near total thyroidectomy placed at the lower sides of the neck results in a cosmetic scar which is easily covered by the collar, and was safe and effective. We thereby recommend the use of this drain incision for near total thyroidectomy.

Knee awareness and functionality after simultaneous bilateral vs unilateral total knee arthroplasty

AIM: To investigate knee awareness and functional outcomes in patients treated with simultaneous bilateral vs unilateral total knee arthroplasty(TKA).METHODS: Through a database search, we identified 210 patients who had undergone unilateral TKA(UTKA) and 65 patients who had undergone simultaneous bilateral TKA(SBTKA) at our institution between 2010 and 2012. All TKAs were cemented and cruciate retaining. The mean follow-up period was 3.2(2 to 4) years. All the patients had symptomatic and debilitating unilateral or bilateral osteoarthritis for which all conservative and non-surgical treatments were failed, thus preoperatively the patients had poor functionality. All patients were asked to complete Forgotten Joint Score(FJS) and Oxford Knee Score(OKS) questionnaires. The patients were matched according to age, gender, year of surgery, Kellgren-Lawrence score and pre- andpostoperative overall knee alignment. The FJS and OKS questionnaire results of the two groups were then compared. RESULTS: A mixed-effects model was used to analyze differences between SBTKA and UTKA. OKS: The mean difference in the OKS between the patients who had undergone SBTKA and those who had undergone UTKA was 1.5, which was not statistically significant(CI =-0.9:4.0, P-value = 0.228). The mean OKS of the SBTKA patients was 37.6(SD = 9.0), and the mean OKS of the UTKA patients was 36.1(SD = 9.9). FJS: The mean difference in the FJS between the patients who had undergone SBTKA and those who had undergone UTKA was 2.3, which was not statistically significant(CI =-6.2:10.8, P-value = 0.593). The mean FJS of the SBTKA patients was 59.9(SD = 27.5), and the mean FJS of the UTKA patients was 57.5(SD = 28.8). CONCLUSION: SBTKA and UTKA patients exhibited similar joint functionality and knee awareness. Our results support the use of SBTKA in selected patients suffering from clinically symptomatic bilateral osteoarthritis.

Should we use similar perioperative protocols in patients undergoing unilateral and bilateral one-stage total knee arthroplasty?

BACKGROUND Bilateral one-stage total knee arthroplasty(BTKA)is now in greater use as an alternative option for patients with bilateral end-stage knee arthropathy.However,postoperative pain and disablement during convalescence from BTKA,and procedure-related complications have been concerning issues for patients and surgeons.Although some studies reported that BTKA in selected patients is as safe as the staged procedure,well-defined guidelines for patient screening,and perioperative care and monitoring to avoid procedure-related complications are still controversial.AIM To compare the perioperative outcomes including perioperative blood loss(PBL),cardiac biomarkers,pain intensity,functional recovery,and complications between unilateral total knee arthroplasty(UTKA)and BTKA performed with a similar perioperative protocol.METHODS We conducted a retrospective study on consecutive patients undergoing UTKA and BTKA that had been performed by a single surgeon with identical perioperative protocols.The exclusion criteria of this study included patients with an American Society of Anesthesiologists score>3,and known cardiopulmonary comorbidity or high-sensitivity Troponin-T(hs-TnT)>14 ng/L.Outcome measures included visual analogue scale(VAS)score of postoperative pain,morphine consumption,range of knee motion,straight leg raise(SLR),length of stay(LOS),and serum hemoglobin(Hb)and hs-TnT monitored during hospitalization.RESULTS Of 210 UTKA and 137 BTKA patients,those in the BTKA group were younger and more predominately female.The PBL of the UTKA vs BTKA group was 646.45±272.26 mL vs 1012.40±391.95 mL(P<0.01),and blood transfusion rates were 10.48%and 40.88%(P<0.01),respectively.Preoperative Hb and body mass index were predictive factors for blood transfusion in BTKA,whereas preoperative Hb was only a determinant in UTKA patients.The BTKA group had significantly higher VAS scores than the UTKA group at 48,72,and 96 h after surgery,and also had a significantly lower degree of SLR at 72 h.The BTKA group also had a significantly longer LOS than the UTKA group.Of the patients who had undergone the procedure,5.71%of the UTKA patients and 12.41%of the BTKA patients(P=0.04)had hs-TnT>14 ng/L during the first 72 h postoperatively.However,there was no difference in other outcome measures and complications.CONCLUSION Following similar perioperative management,the blood transfusion rate in BTKA is 4-fold that required in UTKA.Also,BTKA is associated with higher pain intensity at 48 h postoperatively and prolonged LOS when compared to the UTKA.Hence,BTKA patients may require more extensive perioperative management for blood loss and pain,even if having no higher risk of complications than UTKA.

Total thyroidectomy is safer with identification of recurrent laryngeal nerve

Objective:To investigate the effect of recurrent laryngeal nerve(RLN)identification on the complications after total thyroidectomy and lobectomy.Methods:Total 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively.Patients were divided into two groups:RLN identified (Group A)or not(Group B).The two groups were compared for RLN injury and hypocalcaemia.Results:The numbers of patients and nerves at risk were 71 and 129 in Group A,and 63 and 121 in Group B,respectively.RLN injury in Group A(0)was sig- nificantly lower than that in Group B(57.9%)patients,75.8%nerves)for the numbers of patients(P=0.016)and nerves at risk (P=0.006).Temporary hypocalcaemia was significantly higher in Group A than in Group B(1424.1%vs 610.3%,P=0.049). Permanent complications in Group B were significantly higher than those in Group A(1320.6%vs 45.6%,P=0.009).Con- clusion:RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy.

Drainage after total thyroidectomy or lobectomy for benign thyroidal disorders

Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.

Thromboelastographic Profile of Patients with Hyperparathyroidism Secondary to Chronic Kidney Failure Submitted to Total Parathyroidectomy

Coagulopathy in surgical patients can cause perioperative complications, as both bleeding and thromboembolic events increase surgical morbimortality. The recognition of preexisting disorders and the understanding of the dynamic changes in hemostasis during surgery are prerequisites of safe patient management. The perioperative management of patients with chronic kidney failure is a huge challenge due to both the hypercoagulable state and increased risk of bleeding. Classic laboratory exams performed for the evaluation of blood clotting seem insufficient regarding the determination of the risk of bleeding and thrombosis in surgical patients. As patients with chronic kidney failure develop secondary hyperparathyroidism, the aim of the present study was to describe a case series and correlate the perioperative thromboelastographic profile of patients with chronic kidney failure submitted to parathyroidectomy with their secondary hyperparathyroidism.

Total Thyroidectomy in Multinodular Goiter: An African Experience

Introduction: Total thyroidectomy is an operation that involves the surgical removal of the whole thyroid gland, with the preservation of the parathyroid glands. The aim of the present study was to assess the complication rates of total thyroidectomy on benign indication and first-time thyroid surgery and investigate the early outcome after opotherapy. Materials and Methods: In this retrospective study, patients who underwent total thyroidectomy for benign multinodular goiter in the department of thoracic surgery in our Hospital from January 2012 to December 2014 were included. In postoperative time, we evaluated surgical complication, histopathological examination and opotherapy. Results: A total 53 patients underwent total thyroidectomy for multmodular goiter;they were 49 (92.45%) bilateral and 4 (7.55%) unilateral (recurrence). The mean age was 47 years and mean diameter of goiter was 10.75 cm. Among the patients 88.68% were females and 11.32% were male. Preoperative hormonal statuses were (70%) in euthyroid and (30%) hyperthyroid following surgery complications like transient laryngeal nerve palsy (3.77%), transient hypocalcemia (7.55%), hematoma (1.9%) and wound infection (1.9%). On histopathological examination of the surgical specimen, 5.7% were reported to be malignant. Six month following surgery 92.45% of patients was a good hormonal balance. Conclusion: Total thyroidectomy for multinodular goiter has a low morbidity and mortality;this procedure olves both the problem of recurrence of disease and reintervention. The opotherapy is doable with a good hormonal balance.

Classic clamp-and-tie total thyroidectomy for large goiters in the modern era:To drain or not to drain?

AIM: To evaluate the role of drains in clamp-and-tie total thyroidectomy(c TT) for large goiters. METHODS: A hundred patients were randomized into group D(drains maintained for 24 h) and ND(no drains). We recorded epidemiological characteristics, thyroid pathology, hemostatic material, intraoperative events, operative time and difficulty, blood loss, biochemical and hematological data, postoperative vocal alteration and pain, discomfort, complications, blood in drains, and hospitalization.RESULTS: The groups had comparable preoperative characteristics, pathology, intraoperative and postoperative data. Hemostatic material was used in all patients of group ND. Forty patients in group D and 9 in ND felt discomfort(P < 0.001). CONCLUSION: Drains in c TT for large goiters give no advantage or disadvantage to the surgeon. The only "major disadvantage" is the discomfort for the patient. Inversely, drains probably influence surgeons' serenity,especially when c TT is performed in nonspecialized departments.

Evaluation of the Morbidity and Complications of Total Thyroidectomy: Systematic Literature Review

This scientific problem is aiming to talk about the evaluation of morbidity and complications of total thyroidectomy. The presented review was conducted by searching in Medline, Embase, Web of Science, Science Direct, BMJ journal, and Google Scholar for, researches, review articles, and reports, published over the past years, which was searched up to June 2021 for published and unpublished studies and without language restrictions. If limitless lookup had comparable findings, we randomly chosen one or two to keep away from repetitive results. Based on the findings and effects of this review, the success of total thyroidectomy will beautify if we furnish large cognizance to advances in intervention, developing new methods and education. Surgeon responsiveness, nursing training will aid too in accomplishing this goal.

Post Thyroidectomy Assessment of Intact Parathyroid Hormone for Early Prediction of Hypocalcaemia

Background: As the half-life of intact parathyroid hormone (iPTH) is very low, it reflects parathyroid insufficiency within minutes to hours after total thyroidectomy. Therefore, iPTH level assessment in the postoperative period can be used to predict the development of hypocalcaemia. The optimal time point to measure serum iPTH is important for the accurate prediction of hypocalcaemia. Aim: This paper aims to evaluate the ability of iPTH as an early predictive marker of hypocalcaemia and determine which time iPTH is more able to predict postoperative hypocalcaemia. Method: This prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, BSMMU, Dhaka, from July 2020 to December 2021, with 67 patients who underwent total thyroidectomy. iPTH levels were measured on the day before the operation and at 1 hour, 4 hours, and 24 hours after the operation. S.calcium levels were measured on the day before the operation and 1st postoperative day. All the data were compiled and sorted properly and were analyzed statistically. Results: Postoperative hypocalcaemia developed in 18 cases, with an incidence of 26.9%. Pearson correlation showed a significant correlation between postoperative iPTH at 1 hr, 4 h, and 24 hr with 1st postoperative calcium value. The Receiver operating characteristic (ROC) curve was processed for the postoperative iPTH at 1 hr, 4 h, and 24 hr. The sensitivity, specificity, cut-off value, and mean AUC found 93.9%, 94.4%, ≤14.0, 0.988;95.9%, 94.4%, ≤09.5, 0.993 and 91.8%, 94.4%, ≤11.0, 0.993 respectively. Conclusion: iPTH can be used as an early predictor of post-thy-roidectomy hypocalcaemia. 4 hr iPTH showed more sensitivity and specificity for a cut-off value near the laboratory reference range.

Comparative Study between Robotic Total Thyroidectomy with Central Lymph Node Dissection via Bilateral Axillo-breast Approach and Conventional Open Procedure for Papillary Thyroid Microcarcinoma

Background： A large proportion of the patients with papillary thyroid microcarcinoma are young women. Therefore, minimally invasive endoscopic thyroidectomy with central neck dissection （CND） emerged and showed well-accepted results with improved cosmetic outcome, accelerated healing, and comforting the patients. This study aimed to evaluate the safety and effectiveness of robotic total thyroidectomy with CND via bilateral axillo-breast approach （BABA）, compared with conventional open procedure in papillary thyroid microcarcinoma. Methods： One-hundred patients with papillary thyroid microcarcinoma from March 2014 to January 2015 in Jinan Military General Hospital of People＇s Liberation Army （PLA） were randomly assigned to robotic group or conventional open approach group （17 = 50 in each group）. The total operative time, estimated intraoperative blood loss, numbers of lymph node removed, visual analog scale （VAS）, postoperative hospital stay time, complications, and numerical scoring system （NSS, used to assess cosmetic effect） were analyzed. Results： The robotic total thyroidectomy with CND via BABA was successfully performed in robotic group. There were no conversion from the robotic surgeries to open or endoscopic surgery. The subclinical central lymph node metastasis rate was 35%. The mean operative time of the robotic group was longer than that of the conventional open approach group （118.8± 16.5 min vs. 90.7± 10.3 min, P 〈 0.05）. The study showed significant differences between the two groups in terms of the VASs （2.1 ± 1.0 vs. 3.8 ±~ 1.2, P 〈 0.05） and NSS （8.9 ± 0.8 vs. 4.8 ± 1.7, P 〈 0.05）. The differences between the two groups in the estimated intraoperative blood loss, postoperative hospital stay time, numbers of lymph node removed, postoperative thyroglobulin levels, and complications were not statistically significant （all P 〉 0.05）. Neither iatrogenic implantation nor metastasis occurred in punctured porous channel or chest wall in both groups. Postoperative cosmetic results were very satisfactory in the robotic group. Conclusions： Robotic total thyroidectomy with CND via BABA is safe and effective for Chinese patients with papillary thyroid microcarcinoma who worry about the neck scars.

不同甲状腺切除术在分化型甲状腺癌中的对比分析

目的分析次全甲状腺切除手术和全甲状腺切除手术在分化型甲状腺癌中的干预效果差异。方法选择2017年7月—2020年7月淄博市妇幼保健院收治的76例分化型甲状腺癌患者为研究样本,采取随机数字排列表法将其分成A组与B组,各38例。A组患者予以全甲状腺切除手术干预,B组患者予以次全甲状腺切除手术干预。对比2组患者治疗总有效率、手术过程中出血量、手术时间以及住院时间及并发症发生率。结果A组治疗总有效率为97.37%,高于B组的81.58%(P<0.05)。A组住院时间分别为(6.51±1.03)d,B组为(6.57±1.09)d,差异无统计学意义(P>0.05)。B组患者手术过程中出血量为(93.20±5.11)mL,多于A组的(50.19±3.56)mL,差异有统计学意义(P<0.05)。B组患者手术时间为(112.57±6.98)min,长于A组的(70.96±4.87)min(P<0.05)。A组并发症发生率为36.84%,高于B组的13.16%(P<0.05)。A组术后引流量为(30.34±4.43)mL,少于B组的(43.12±4.86)mL(P<0.05);A组引流管拔出时间为(3.34±0.23)d,短于B组的(4.10±0.29)d(P<0.05)。结论分化型甲状腺癌患者采用全甲状腺切除手术治疗可提升治疗效果,降低术中出血量,缩短手术时间;但是术后并发症较多,因此需要依据患者实际情况合理选择手术方式。

甲状腺乳头状癌颈中线淋巴结分区预测对侧中央区淋巴结转移情况的价值研究

目的分析甲状腺乳头状癌(PTC)患者对侧中央区淋巴结(Cont-CLNs)转移的相关因素,评估颈中线淋巴结(Mid-CLNs)分区在识别Cont-CLNs转移中的临床价值。方法选取2021年1月至2023年6月广东省佛山市第一人民医院进行甲状腺全切除术和双侧中央区颈淋巴清扫术(CND)治疗PTC的125例患者,组织病理学检查评估的主要因素包括:原发肿瘤最大直径、多灶性、被膜侵犯、腺外浸润、桥本氏甲状腺炎、淋巴结转移分区。组间数据比较采用单因素方差分析。利用多因素Logistic回归分析法分析Cont-CLNs转移的危险因素,计算受试者工作特征(ROC)曲线下面积,分析对侧Mid-CLNs转移对Cont-CLNs转移的预测效能。结果125例PTC患者中,107(85.60%)例患者发生Mid-CLNs转移,57.60%(72/125)的患者发生患侧Mid-CLNs转移,28.80%(36/125)的患者发生对侧Mid-CLNs转移。在单因素分析中,多灶性(P=0.004)、被膜侵犯(P=0.002)、腺外浸润(P=0.048)、对侧Mid-CLNs转移(P<0.01)和Ipis-CLNs转移(P=0.043)与Cont-CLNs转移的发生有显著相关性。而Mid-CLNs转移(P=0.422)、患侧Mid-CLNs转移(P=0.856)与Cont-CLNs转移的发生则无相关性。多因素Logistic回归分析发现,Ipis-CLNs转移(P=0.013,OR=2.065)和对侧Mid-CLNs转移(P=0.008,OR=2.072)发生越多,Cont-CLNs转移发生的概率越大。且对侧Mid-CLNs转移阳性对Cont-CLNs转移预测的AUC为0.664(95%CI=0.554~0.774,P=0.006),敏感度为76.19%,特异度为56.60%。结论对侧Mid-CLNs转移是Cont-CLNs转移的独立危险因素,且对预测Cont-CLNs转移具有较为良好的诊断价值。

两种不同剂量碘-131对非远处转移性高危分化型甲状腺癌全切术后患者DTC的应用效果

目的探讨两种不同剂量碘-131对非远处转移性高危分化型甲状腺癌(DTC)全切术后患者的应用效果。方法回顾性分析86例非远处转移性高危DTC患者的临床资料,所有患者均行DTC全切术,并按照碘-131治疗剂量的不同分成低剂量组(100~150 mCi)和高剂量组(150~200 mCi),前者为45例,后者为41例,治疗3个月,随访1年。比较两组相关临床治疗指标(清甲成功率、无病生存率、住院隔离时间)、甲状腺癌特异性生命质量量表(THYCA-QoL)和不良反应发生情况的差异。结果治疗及随访结束后,两组的清甲成功率无明显差异(P<0.05),低剂量组的无病生存率(95.56%)高于高剂量组(80.49%),且住院隔离时间短于高剂量组(P<0.05);两组生理功能和活动、心理功能、症状或对生活影响评分均高于同组治疗前,且低剂量组THYCA-QoL评分均高于高剂量组(P<0.05);低剂量组不良反应发生率(8.89%)低于高剂量组(29.27%)(P<0.05)。结论低剂量和高剂量碘-131对于非远处转移性高危DTC全切术后患者的治疗效果相当,但前者更有利于缩短住院隔离时间,提高无病生存率,减少不良反应的发生,进而提高生存质量。
