Objective:To retrospectively analyze the feasibility of undergoing day surgery at 3rd week after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children.Methods:The clinical data from children who underwent day surgery from November 1, 2022 to February 28, 2023, with operation time ≤1 h, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, regardless of gender, aged≤14 yr, with body mass index of 10-30 kg/m 2, were divided into SARS-CoV-2 group and control group according to whether the children had been infected with the SARS-CoV-2. The main outcome measure was the incidence of respiratory system-related complications within 30 days after surgery. Secondary outcome measures included the rate of unplanned ventilation, delayed discharge and secondary admission within 30 days after surgery. Preoperative creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), hemoglobin (Hb), white blood cell count, C-reactive protein (CRP) level, grade of oropharyngeal mucosa inflammation, operation time, emergence time, intraoperative respiratory depression, laryngeal spasm, hypoxemia, hypotension, incidence of sinus bradycardia and rate of additional rescue drugs were recorded. Results:There were 337 cases in SARS-CoV-2 group and 1 396 cases in control group. Compared with control group, CK-MB concentrations were significantly increased, and the Hb concentration was decreased before surgery in SARS-CoV-2 group ( P<0.05). There were no statistically significant differences in the incidence of respiratory system-related complications, unplanned ventilation, delayed discharge and rate of postoperative secondary admission, preoperative AST and ALT concentrations, white blood cell count, CRP concentrations, grade of oropharyngeal mucosa inflammation, operation time, intraoperative respiratory depression, laryngeal spasm, hypoxemia, hypotension, incidence of sinus bradycardia, rate of additional rescue drugs and emergence time between the two groups ( P>0.05). Conclusions:Feasibility of undergoing day surgery is good at the third week after being infected with the SARS-CoV-2 in children.

Clinical efficacy of two different internal fixations in treating femoral intertrochanteric fractures in older adult patients / 中国基层医药

Objective:To investigate the clinical efficacy of two different internal fixations in the treatment of femoral intertrochanteric fractures in older adult patients.Methods:The clinical data of 152 older adult patients with femoral intertrochanteric fractures who were treated at the Second People's Hospital of Hefei from January 2019 to December 2022 were retrospectively analyzed. All patients underwent closed reduction and internal fixation surgery. They were divided into two groups based on the different types of internal fixations used. Among them, 76 patients received internal fixation using proximal femoral intramedullary nails (group A), while 76 patients received internal fixation using Intertan nails (group B). The intraoperative blood loss volume, surgical time, postoperative complications, fracture healing time, and hip joint function score were compared between the two groups.Results:The intraoperative blood loss volume in group A was (197.11 ± 37.85) mL, which was significantly less than that in group B [(226.84 ± 54.17) mL, t = 1.62, P < 0.001]. Surgical time in group A was (71.16 ± 15.64) minutes, which was significantly shorter than that in group B [(78.49 ± 15.88) minutes, t = 1.67, P < 0.001]. The fracture healing time in group A was (13.29 ± 0.94) weeks, which was not significantly different from that in group B [(13.20 ± 0.64) weeks, t = 0.33, P > 0.05]. However, the incidence of postoperative complications in group A was 5.26% (4/76), which was significantly higher than 1.32% (1/76) in group B ( χ2 = 4.04, P = 0.048). At 1 and 3 months and 1 year after surgery, the hip joint function score in group A was (63.13 ± 2.41) points, (73.50 ± 3.99) points, and (84.13 ± 7.57) points, respectively, and it was (68.65 ± 2.65) points, (79.07 ± 3.38) points, and (89.56 ± 7.71) points, respectively, in group B. At the above-mentioned time points, the difference in hip joint function score between the two groups was statistically significant ( t = 1.89, 2.48, 2.49, all P < 0.001). Conclusion:Both internal fixation methods have significant therapeutic effects on femoral intertrochanteric fractures. Internal fixation using Intertan nails leads to higher hip joint function scores and fewer postoperative complications compared with internal fixation using proximal femoral intramedullary nails, but it results in more blood loss and a longer surgical time.

Preoperative co-application of bevacizumab and tissue plasminogen activator in vitrectomy for proliferative diabetic retinopathy

ABSTRACT Purpose: To investigate the clinical benefits of the co-application of bevacizumab and tissue plasminogen activator as adjuncts in the surgical treatment of proliferative diabetic retinopathy. Methods: Patients who underwent vitrectomy for proliferative dia-betic retinopathy complications were preoperatively given in-travitreal injection with either bevacizumab and tissue plasminogen activator (Group 1) or bevacizumab alone (Group 2). Primary outcomes were surgery time and number of intraoperative iatrogenic retinal breaks. Secondary outcomes included changes in the best-corrected visual acuity and postoperative complications at 3 months postoperatively. Results: The mean surgery time in Group 1 (52.95 ± 5.90 min) was significantly shorter than that in Group 2 (79.61 ± 12.63 min) (p<0.001). The mean number of iatrogenic retinal breaks was 0.50 ± 0.59 (0-2) in Group 1 and 2.00 ± 0.83 (0-3) in Group 2 (p<0.001). The best-corrected visual acuity significantly improved in both groups (p<0.001). One eye in each group developed retinal detachment. Conclusion: Preoperative co-application of bevacizumab and tissue plasminogen activator as adjuncts in the surgical treatment of proliferative diabetic retinopathy shortens the surgery time and reduces the number of intraoperative iatrogenic retinal breaks.

Timing of Surgery and Pre-operative Physiological Parameters as Clinical Predictors of Surgical Outcomes in Traumatic Subaxial Cervical Spine Fractures and Dislocations / Momento da cirurgia e parâmetros fisiológicos pré-operatórios como fatores preditivos clínicos de desfechos cirúrgicos em fraturas e luxações traumáticas subaxiais da coluna cervical

Abstract Objective To evaluate the risk factors and outcomes in patients surgically treated for subaxial cervical spine injuries with respect of the timing of surgery and preoperative physiological parameters of the patient. Methods 26 patients with sub-axial cervical spine fractures and dislocations were enrolled. Demographic data of patients, appropriate radiological investigation, and physiological parameters like respiratory rate, blood pressure, heart rate, PaO2 and ASIA impairment scale were documented. They were divided pre-operatively into 2 groups. Group U with patients having abnormal physiological parameters and Group S including patients having physiological parameters within normal range. They were further subdivided into early and late groups according to the timing of surgery as Uearly, Ulate, Searly and Slate. All the patients were called for follow-up at 1, 6 and 12 months. Results 56 percent of patients in Group S had neurological improvement by one ASIA grade and a good outcome irrespective of the timing of surgery. Patients in Group U having unstable physiological parameters and undergoing early surgical intervention had poor outcomes. Conclusion This study concludes that early surgical intervention in physiologically unstable patients had a strong association as a risk factor in the final outcome of the patients in terms of mortality and morbidity. Also, no positive association of improvement in physiologically stable patients with respect to the timing of surgery could be established.

Resumo Objetivo Avaliar os fatores de risco e os desfechos em indivíduos submetidos ao tratamento cirúrgico de lesões subaxiais da coluna cervical em relação ao momento da cirurgia e aos parâmetros fisiológicos pré-operatórios dos pacientes. Métodos O estudo incluiu 26 pacientes com fraturas e luxações subaxiais da coluna cervical. Dados demográficos, investigação radiológica apropriada e parâmetros fisiológicos, como frequência respiratória, pressão arterial, frequência cardíaca, pressão parcial de oxigênio (PaO2) e escalas de disfunção da American Spine Injury Association (ASIA), foram documentados. No período pré-operatório, os pacientes foram divididos em dois grupos. O grupo instável (I) continha pacientes com parâmetros fisiológicos anormais e o grupo estável (E) era composto por pacientes com parâmetros fisiológicos dentro da faixa de normalidade. Os pacientes foram ainda subdivididos em grupos de tratamento precoce e tardio de acordo com o momento da cirurgia como Iprecoce, Itardio, Eprecoce e Etardio. Todos os pacientes foram chamados para consultas de acompanhamento em 1, 6 e 12 meses. Resultados Cinquenta e seis por cento dos pacientes do grupo E apresentaram melhora neurológica em um grau ASIA e desfecho bom independentemente do momento da cirurgia. Os desfechos em pacientes do grupo I com parâmetros fisiológicos instáveis e submetidos à intervenção cirúrgica precoce foram maus. Conclusão Este estudo conclui que a intervenção cirúrgica precoce em pacientes com instabilidade fisiológica teve forte associação como fator de risco no desfecho final em termos de mortalidade e morbidade. Além disso, não foi possível estabelecer nenhuma associação positiva de melhora em pacientes com estabilidade fisiológica em relação ao momento da cirurgia.

The Impact of COVID-19 on the Timing of Rotator Cuff Repair and Method of Postoperative Follow-up / Impacto da COVID-19 no momento de reparo do manguito rotador e método de acompanhamento pós-operatório

Abstract Objective Rotator cuff repair (RCR) is one of the most common arthroscopic procedures. Our investigation aims to quantify the impact that the COVID-19 pandemic had on RCR, specifically on patients with acute, traumatic injuries. Methods Institutional records were queried to identify patients who underwent arthroscopic RCR between March 1st to October 31st of both 2019 and 2020. Patient demographic, preoperative, perioperative, and postoperative data were collected from electronic medical records. Inferential statistics were used to analyze data. Results Totals of 72 and of 60 patients were identified in 2019 and in 2020, respectively. Patients in 2019 experienced shorter lengths of time from MRI to surgery (62.7 ± 70.5 days versus 115.7 ± 151.0 days; p = 0.01). Magnetic resonance imaging (MRI) scans showed a smaller average degree of retraction in 2019 (2.1 ± 1.3 cm versus 2.6 ± 1.2 cm; p = 0.05) butnodifference in anterior toposterior tear size between years (1.6 ± 1.0 cm versus 1.8 ± 1.0 cm; p = 0.17). Less patients in 2019 had a tele-health postoperative consultation with their operating surgeon compared with 2020 (0.0% versus 10.0%; p = 0.009). No significant changes in complications (0.0% versus 0.0%; p > 0.999), readmission (0.0% versus 0.0%; p > 0.999), or revision rates (5.6% versus 0.0%; p = 0.13) were observed. Conclusion From 2019 to 2020, there were no significant differences in patient demographics or major comorbidities. Our data suggests that even though the time from MRI to surgery was delayed in 2020 and telemedicine appointments were necessary, RCR was still performed in a time in early complications. Level of Evidence III.

Surgical Use of Supraclavicular Artery Flap for Head and Neck Cancer Defects Repair: Personal Experience

Abstract Introduction For a long time, major surgical defects after oncological surgery have always been challenging cases for surgeons in terms of wound healing and covering technique. Objectives To demonstrate the feasibility of supraclavicular artery flap (SCAF) in the reconstruction of surgical defects in those "fragile" patients undergoing oncological surgery who could not possibly have endured the timeframes involved in using microvascular free flaps. Methods Between January 2018 and January 2019, at the Azienda Socio Sanitaria Territoriale (ASST) Bergamo Est Hospital (Bergamo, Italy), we reported the cases of 11 patients in whom the SCAF was used for surgical reconstruction after oncological surgery in our Otolaryngology Department. The median age of the 11 patients was 68.7 years old. Results The SCAF has proved, in almost all 11 cases in which it was used, to be very reliable and, above all, easy and quick to make in those "fragile" patients without the need for further intervention. There was only one case in which the resection involved the auricle entirely and a small area of perimeatal bone exposure occurred, which, anyway, healed by secondary intention. Conclusion The SCAF is an extremely versatile flap for head and neck surgery to be considered especially for fragile and vulnerable patients who cannot undergo prolonged surgical time. Moreover, this technique has also shown high feasibility in small hospitals where there is not a plastic surgery department and the surgeon may face the difficulty of practicing surgical reconstruction after enlarged resection.

Analysis of influencing factors of operative time and postoperative complications of retroperitoneal laparoscopic adrenalectomy and establishment of predicting model / 国际外科学杂志

Objective:To explore the factors affecting the operative time and postoperative complications of retroperitoneal laparoscopic adrenalectomy, and to establish a predicting model.Methods:A total of 298 patients who underwent retroperitoneal laparoscopic adrenalectomy at Beijing Friendship Hospital, Capital Medical University from October 2017 to July 2022 were retrospectively analyzed.Observe and record the patient′s operative time, postoperative complications, and record the possible influencing factors, including gender, age, body mass index (BMI), tumor size, Mayo adhesive probability (MAP) score, and distance from the lower pole of the adrenal tumor to the upper pole of the kidney (DAK), distance from the lower pole of the adrenal tumor to the renal pedicle (DARP), distance between the skin and Gerota′s fascia (S-GF), perinephric fat distance (PNF), posterior adiposity index (PAI), thickness of waist fat, thickness of subcutaneous fat, etc. Univariate analysis was performed on the above influencing factors with the operative time as the dependent variable, and all variables with statistical significance were included in the linear regression analysis, and get the regression equation. Then take the occurrence of postoperative complications as the dependent variable, and the above-mentioned influencing factors as independent variables, and incorporate univariate and multivariate Logistic analysis to obtain the relevant influencing factors of postoperative complications, and use R software to establish a risk prediction nomogram model for postoperative complications.Results:Male patients ( P<0.001) with high BMI ( P=0.001), thick waist fat ( P=0.013), high MAP score ( P<0.001), and high PNF ( P<0.001) were expected to require longer operative time, and get the linear regression equation: operative time=75.892+ 4.672×MAP score+ 13.574 (if male)+ 0.023×BMI+ 0.792×PNF+ 1.968×thickness of waist fat ( P<0.001); according to multivariate Logistic regression, short DARP ( P=0.003), high PAI ( P=0.002), and long operative time ( P=0.023) increase the risk of postoperative complications, and get a risk prediction nomogram model for postoperative complications. At the same time, postoperative complications were more likely to occur when the expected operative time was longer than 77.5 minutes. Conclusions:The prediction models of operative time and postoperative complications of retroperitoneal laparoscopic adrenalectomy established in this study provide an objective and reliable assessment. When the estimated operative time is longer than 77.5 minutes, the operation is more difficult and postoperative complications risk is higher and should be performed by more experienced doctors.

Clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps / 中国基层医药

Objective:To investigate the clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps.Methods:The clinical data of 103 patients with gallbladder polyps who received laparoscopy combined with choledochoscopy treatment in The First People's Hospital of Lianyungang from February 2016 to March 2018 were retrospectively analyzed. Sixty-five patients in the observation group underwent gallbladder wall sutures with absorbable barbed wires, and thirty-eight patients in the control group underwent gallbladder wall sutures with common absorbable wires. The operative time, gallbladder wall suture time, intraoperative blood loss, average hospitalization time, and postoperative bile leakage were compared between the two groups.Results:There were no significant differences in intraoperative blood loss and average hospitalization time between the two groups ( P = 0.312, P = 0.114). In the observation group, gallbladder wall suture time and operative time were (5.58 ± 1.14) minutes and (60.71 ± 11.03) minutes, respectively, which were shorter than (6.32 ± 1.04) minutes and (68.24 ± 9.61) minutes in the control group ( t = 3.23, 3.50, P = 0.002, 0.001). No bile leakage occurred in the observation group and bile leakage occurred in four (10.5%) patients in the control group. There was a significant difference in bile leakage between the observation and control groups ( χ2 = 4.57, P = 0.032). Conclusion:Absorbable barbed wires for gallbladder wall sutures during operation in laparoscopy combined with choledochoscopy treatment of gallbladder polyps is safe and feasible. It can markedly shorten gallbladder wall suture time and operative time, decrease the incidence of bile leakage, and has a clinical advantage over common absorbable wires.

Methods:The clinical data and follow-up results of 56 patients with refractory hyperthyroidism who underwent laparoscopy or open surgery in Affiliated Nanhua Hospital of University of South China from January 2019 to August 2020 were retrospectively analyzed.Results:Among the 56 patients, there were 6 men and 50 women. Thirty-six (64.3%) patients underwent endoscopic surgery and twenty (35.7%) patients underwent open surgery. The operation time was (132.0 ± 32.0) minutes. Intraoperative blood loss was (32.4 ± 27.8) mL. Postoperative parathyroid hormone level was (27.8 ± 18.3) ng/L. Forty-nine (87.5%) patients showed benign pathology results after surgery. After surgery, 14 (25.0%) patients had hypothyroidism, including 7 (12.5%) patients with hyperthyroidism combined with thyroid cancer. There were no patients with permanent hypothyroidism or recurrent laryngeal nerve paralysis. All patients had a good prognosis and satisfactory surgical results.Conclusion:With the update of preoperative preparation methods for hyperthyroidism, the increasing maturity of thyroid surgery technology, and the use of new energy instruments and technologies, surgical treatment is undoubtedly a good treatment method for patients with refractory hyperthyroidism or a suspected malignant tumor.Objevtives:To investigate the indications and clinical efficacy of surgical treatment in patients with refractory hyperthyroidism.

Application of self-developed rapid tracheotomy apparatus for acute tracheotomy / 中国基层医药

Objective:To investigate the application effects of self-developed rapid tracheotomy apparatus for acute tracheotomy.Methods:A total of 120 patients who underwent an acute tracheotomy in the Weihai Branch of The 970 Hospital of PLA Joint Logistics Support Force from January 2019 to December 2020 were included in this study. These patients were randomly divided into a rapid group and a conventional group, with 60 patients in each group. Patients in the rapid group underwent tracheotomy with a self-developed rapid tracheotomy apparatus. Patients in the conventional group underwent the standard steps of traditional tracheostomy. The operation time, incision length, amount of bleeding, and incidence of postoperative complications were compared between the two groups.Results:The operation time in the rapid group was significantly shorter than that in the conventional group [(4.5 ± 0.9) minutes vs. (19.3 ± 4.7) minutes, t = 23.86, P < 0.001]. The length of incision in the rapid group was significantly shorter than that in the conventional group [(2.8 ± 0.3) cm vs. (4.2 ± 1.3) cm, t = 8.68, P < 0.001]. The amount of bleeding during the surgery in the rapid group was significantly less than that in the conventional group [(4.4 ± 1.6) mL vs. (11.8 ± 4.1) mL, t = 12.99, P < 0.001]. The incidence of postoperative complications in the rapid group was significantly lower than that in the conventional group ( χ2 = 4.66, P = 0.031). Conclusion:The self-developed rapid tracheotomy apparatus for acute tracheotomy can be used to establish an artificial airway quickly and minimally invasively by simplifying the operational steps. It is remarkably innovative to increase safety with open-view operations and decrease the incidence of complications. It can be repeatedly sterilized and reused, which is worthy of clinical application and popularization.

The learning curve of MAKO-assisted total knee arthroplasty / 中华骨科杂志

Objective:To explore the learning curve of MAKO-assisted total knee arthroplasty.Methods:From May 2021 to September 2022, 136 patients were conducted MAKO-assisted total knee arthroplasty in the PLA General Hospital, including 37 males and 99 females, 65.53±7.01 years old (range 54-80 years). All cases were patients with unilateral knee osteoarthritis. The operations were performed by three surgeons, respectively. Sixty-one cases were performed by surgeon 1, 47 cases were performed by surgeon 2, and 28 cases were performed by surgeon 3. Record the time of each step during the operation, and measure the limb alignment in X-ray. The statistical difference between the two groups was compared by t test by SPSS. The cumulative sum control chart (CUSUM) learning curve was modeled by curve fitting and R2 was used to testify the goodness. Results:The total operation time of the three surgeons was 114.3±25.1 min, 109.8±10.9 min, and 118.6±15.1 min, respectively. The time of each step in the first 10 cases and the last 10 cases of operator 1-3 was counted. The osteotomy time of surgeons 1, 2 and 3 in the final 10 cases was less than that in the initial 10 cases (surgeon 1: 13.5 ± 3.41 min vs. 8.0±1.58 min, t=4.30, P=0.001; surgeon 2: 13.7±3.02 min vs. 8.0± 2.58 min, t=4.77, P=0.001; surgeon 3: 15.3±3.97 min vs. 11.0±2.38 min, t=2.87, P=0.010), and the difference was statistically significant. The CUSUM of osteotomy was calculated and the curve was fitted. The highest point of the curve of the three surgeons was in the 16th, 18th and 12th patients, respectively, and the time of osteotomy continued to decline after passing the peak. No statistical differences were found in surgery time for the remaining steps. Comparing the lower alignment angles of intraoperative planning and postoperative X-ray films, the overall difference was greater than 1 degree. The difference was 1.41°±1.32° for operator 1, 1.34°±1.22° for operator 2, and 1.04°±0.88° for operator 3. The percentages of fully accurate implant size planning were 85.2%(52/61), 76.7%(36/47), and 85.7%(24/28), respectively. Conclusion:For MAKO-assisted total knee arthroplasty, the operator can decrease the operation time by practice, which is mainly reflected in the shortening of the osteotomy time. The learning curve threshold is around in the 15th case. The increase in the number of surgeries did not bring about changes in the accuracy of lower extremity alignment.

Objective: To compare the open and closed surgical techniques in hemorrhoid disease in Camagüey province, in the period from January 2021 to January 2023. Methods: An observational, analytical, cross-sectional study was carried out. The universe was made up of 135 patients who attended the consultation with the diagnosis of hemorrhoid disease. A simple random sampling was carried out, where 15 patients from each of the groups were taken to form a total sample of 45 patients, each group was treated with a surgical technique. Results: In relation to sex, the female sex predominated, the surgical time was given at 30 minutes in the open techniques. Postoperative pain as an immediate complication was significant with the use of the classic Whitehead open technique; there were no mediate complications in this study; while in the late ones, anal stenosis was the one that manifested itself the most. Conclusions: There was a predominance of the female sex, the most frequent surgical time was 30 minutes in patients operated with the open technique, in most patients excessive pain was found as an immediate complication with the Milligan-Morgan and classic Whitehead open techniques, but not so with the closed technique of Ferguson. Anal stenosis was the most frequent late surgical complication associated with the classic Whitehead technique.

Effects of proximal femoral intramedullary nail antirotation fixation on intertrochanteric fracture of the femur in 34 patients / 中国基层医药

Objective:To investigate the efficacy of proximal femoral intramedullary nail antirotation fixation in the treatment of intertrochanteric fracture of the femur and its effects on Harris hip scores.Methods:Sixty-eight patients with intertrochanteric fracture of the femur who received treatment in Cixi People's Hospital from April 2018 to October 2019 were included in this study. They were randomly assigned to receive dynamic hip screw fixation (control group, n = 34) or proximal femoral intramedullary nail antirotation fixation (observation group, n = 34). Clinical efficacy, Harris score, surgical indicators, and the incidence of complications were compared between the two groups. Results:The response rate was significantly higher in the observation group than in the control group [94.12% (32/34) vs. 76.47% (26/34), χ2 = 5.81, P < 0.05]. The excellent and good rate of hip function as evaluated by Harris hip scores was significantly higher in the observation group than in the control group [91.18% (31/34) vs. 73.53% (25/34), χ2 = 6.05, P < 0.05]. The operative time, blood loss, incision length, and fracture healing time in the observation group were (51.66 ± 10.52) minutes, (120.26 ± 12.29) mL, (8.09 ± 2.62) cm, and (9.86 ± 2.67) weeks respectively, and those in the control group were (78.32 ± 12.23) minutes, (238.45 ± 17.85) mL, (12.95 ± 3.29) cm, and (13.65 ± 3.46) weeks, respectively. There were significant differences in these indices between the two groups ( t = 14.55, 14.03, 14.85, 14.60, all P < 0.05). The incidence of complications was significantly lower in the observation group than in the control group [5.88% (2/34) vs. 23.53% (8/34), χ2 = 6.51, P < 0.05]. Conclusion:Proximal femoral intramedullary nail antirotation fixation is superior to dynamic hip screw fixation in the treatment of intertrochanteric fracture of the femur. The former increases Harris hip score, decreases the incidence of complications, and is of great clinical innovation.

Objective:To investigate the efficacy of laparoscopic myomectomy with a baseball-style suture technique in the treatment of hysteromyoma.Methods:Sixty patients with hysteromyoma who received treatment in the Department of Obstetrics and Gynecology, The Second People's Hospital of Hefei, China between July 2018 and July 2020 were included in this study. They were randomly assigned to observation and control groups with 30 patients per group. The observation group was subjected to laparoscopic myomectomy with a baseball-style suture technique. The control group was given laparoscopic myomectomy with a continuous suture technique. Intraoperative indices and postoperative complications were compared between the two groups.Results:Operative time in the observation group was significantly shorter than that in the control group [(98.06 ± 35.41) minutes vs. (119.39 ± 33.65) minutes, t = 2.39, P < 0.05]. Intraoperative blood loss in the observation group was significantly less than that in the control group [(28.33 ± 9.56) mL vs. (46.17 ± 13.08) mL, t = 6.36, P < 0.05]. The percentage of intraoperative needle-hole bleeding in the observation group was significantly lower than that in the control group [16.67% (5/30) vs. 46.67% (14/30), χ 2 = 6.23, P < 0.05). The time to anal exhaust and the time to drainage in the observation group were (19.21 ± 5.77) hours and (59.07 ± 18.85) hours, respectively, which were significantly shorter than (25.39 ± 9.65) hours and (77.22 ± 27.07) hours in the control group ( t = 3.01, 3.02, both P < 0.05). The incidence of postoperative fever in the observation group was significantly lower than that in the control group [3.33% (1/30) vs. 26.67% (8/30), χ 2 = 4.70, P < 0.05]. Conclusion:Laparoscopic myomectomy with a baseball-style suture technique is highly effective on hysteromyoma. It can improve the safety of operation and has a great clinical value.

Objective:To investigate the clinical application value of enhanced recovery after surgery using the LEER model in patients subjected to laparoscopic cholecystectomy in basic hospitals of Yi nationality area.Methods:Twenty-six patients who underwent laparoscopic cholecystectomy based on the concept of enhancing recovery after surgery using the LEER model in People's Hospital of Jinkouhe District of Leshan from January to October 2021 were included in the observation group. An additional 20 patients who concurrently underwent laparoscopic cholecystectomy and conventional intervention were included in the control group. Clinical efficacy, postoperative complications and postoperative pain were compared between the two groups.Results:Postoperative fasting time, length of hospital stay, and total hospital days in the observation group were 6 (6, 6) hours, 2 (2, 3) days and 4 (4, 6) days respectively, which were significantly shorter than 24 (24, 36) hours, 5 (5, 6) days, 7 (7, 9) days in the control group ( H = 351.00, 407.50, 458.00, all P < 0.05). Hospitalization cost in the observation group was 5 454.58 (5 014.11, 6 016.58) yuan, which was significantly lower than 6 611.91 (6 192.68, 7 841.73) yuan in the control group ( H = 420.00, P < 0.05). There were no significant differences in operative time and postoperative complications between the two groups (both P > 0.05). At postoperative 6 hours, Visual Analogue Scale score in the observation group was 3 (3, 4) points, and patients with mild pain accounted for 73.07% (19/26). At postoperative 24 hours, Visual Analogue Scale score in the observation group was 2 (2, 3) points, and patients with mild pain accounted for 92.31% (24/26). Overall pain was well controlled after surgery. Patient satisfaction rate in the observation was 96.15% (25/26). All patients recovered and were discharged. Conclusion:Application of enhanced recovery after surgery using the LEER model in patients subjected to laparoscopic cholecystectomy in basic hospitals of Yi nationality area can promote postoperative recovery, contribute to changing the theory of diagnosis and treatment, and improve overall medical quality. The enhanced recovery after surgery protocol using the LEER model has a good application value.

Patients Submitted to Myocardial Revascularization with the Use of Bilateral Internal Thoracic Arteries: Diabetics vs. Non-Diabetics

Abstract Introduction: Use of bilateral internal thoracic artery (BITA) as graft in coronary artery bypass grafting (CABG) is controversial because it is related to higher in-hospital mortality, incidence of sternal wound-related infection, and an increase in surgical time. The primary objective of this study is to evaluate in-hospital mortality and mortality within 30 days from discharge. The secondary objective is to evaluate the occurrence of deep sternal wound infection in a 90-day follow-up. Methods: This is a retrospective review of the medical records of 152 patients undergoing elective CABG with the use of BITA and cardiopulmonary bypass (CPB). These patients were divided into two groups, diabetics and non-diabetics. Patients with acute myocardial infarction and concomitant valvular disease were not included in the sample. Results: Preoperative characteristics did not show significant differences between the groups, which allowed a comparative analysis. The variables electrocardiography time and aortic clamping time were higher in the diabetic group, with a significant statistical difference (P<0.0001). In-hospital mortality occurred in three patients, and there was no mortality up to 30 days in both groups. There was no significant difference in the primary end point between groups (P=0.56). Deep sternal wound infection was present in only one patient and showed no significant difference in the secondary outcome between groups (P=0.40). Conclusion: We did not observe a higher mortality and occurrence of deep sternal wound infection with the use of BITA in diabetic patients compared to non-diabetics, even with greater CPB and aortic clamping times in diabetics.

Efficacy of transumbilical laparoendoscopic single-site supracervical hysterectomy in the treatment of benign uterine diseases / 中国基层医药

Objective:To investigate the efficacy of transumbilical laparoendoscopic single-site supracervical hysterectomy in the treatment of benign uterine diseases.Methods:The clinical data of 39 patients with benign uterine diseases with the volume of uterus less than that at the 14 weeks of pregnancy who underwent supracervical hysterectomy in People's Hospital of Hechuan District of Chongqing, China between January 2018 and December 2019 were retrospectively analyzed. These patients were divided into transumbilical laparoendoscopic single-site supracervical hysterectomy group (single-site group, n = 21) and transumbilical laparoendoscopic multiple-site supracervical hysterectomy group (multiple-site group, n = 18) according to different surgical approaches. Operation time, specimen removal time, intraoperative blood loss, incision suture time, tissue debris shedding rate, postoperative off-bed time, length of hospital stay, pain score on postoperative day 1, time to anal exhaust, and the incidence of complications within 30 days after surgery were compared between the two groups. Results:Tissue debris shedding rate in the single-site group was significantly lower than that in the multiple-site group [0.00% (0/21) vs. 100.00% (18/18), χ2 = 39.00, P < 0.001]. Operation time in the single-site group was significantly longer than that in the multiple-site group [(74.20 ± 9.15) minutes vs. (62.90 ± 6.20) minutes, t = 3.323, P < 0.05). Specimen removal time and incision suture time in the single-site group were (11.10 ± 2.33) minutes and (3.90 ± 0.88) minutes, respectively, which were significantly longer than those in the multiple-site group [(4.90 ± 0.88) minutes, (2.90 ± 0.74) minutes, t = 7.97, 0.386, both P < 0.05]. There were no significant differences in intraoperative blood loss, postoperative off-bed time, pain score on postoperative day 1, length of hospital stay, time to anal exhaust, and the incidence of complications within 30 days after surgery between the two groups (all P > 0.05). Conclusion:Transumbilical laparoendoscopic single-site and multiple-site supracervical hysterectomy can acquire similar short-term surgical outcomes in the treatment of benign uterine diseases at the time of less than 14 weeks of pregnancy and transumbilical laparoendoscopic single-site supracervical hysterectomy can eliminate the long-term complications caused by tissue dissemination.

Clinical effects of anterior cervical discectomy and fusion combined with zero-profile anchored spacer application on cervical spondylosis / 中国基层医药

Objective:To investigate the clinical effects of anterior cervical discectomy and fusion combined with zero-profile anchored spacer (ROI-C) application on cervical spondylosis.Methods:Eighty-nine patients, consisting of 58 males and 31 females, who received anterior cervical discectomy and fusion combined with zero-profile anchored spacer (ROI-C) application in First People's Hospital of Guiyang from May 2015 to May 2018 were retrospectively analyzed. A total of 138 segments were fused. Operative time, intraoperative blood loss, postoperative complications and their incidence were recorded. The Japanese Orthopaedic Association score, Visual Analogue Scale score, and Neck Disability Index score were used to evaluate clinical effects of anterior cervical discectomy and fusion combined with ROI-C application. Imaging examination was performed to determine cervical curvature, intervertebral space height of fused segments, interbody fusion rate and changes in adjacent segments. The stability and long-term effects of postoperative cervical spine were evaluated.Results:All 89 patients were followed up for (25.6 ± 6.8) months (range 12-36 months). In 53 patients who underwent single-segment fusion, operative time was (85.54 ± 12.53) minutes and the amount of blood loss was (58.45 ± 10.24) mL. In 25 patients who underwent two-segment fusion, operative time was (115.57 ± 16.42) minutes and the amount of blood loss was (92.62 ± 12.44) mL. In 9 patients who underwent three-segment fusion, operative time was (148.63 ± 19.42) minutes and the amount of blood loss was (118.54 ± 11.25) mL. In 2 patients who underwent four-segment fusion, operative time and the amount of blood loss were 188 minutes and 175 mL, respectively in one patient and they were 214 minutes and 225 mL in another patient, respectively. With time went during 1 week to 12 months after surgery, Japanese Orthopaedic Association score was greatly increased, Neck Disability Index score was remarkably decreased, and Visual Analogue Scale score was also significantly decreased ( F = 11.25, 26.35, 20.26, all P < 0.05). Swallowing discomfort occurred in only 2 (2.2%) patients. No patients had incision hematoma, infection, hoarseness or choking cough. At 1 week to 12 months after surgery, cervical curvature and the height of intervertebral space of fused segments were superior to those before surgery (both P < 0.05). At 12 months after surgery, X-ray examination revealed bony fusion with no loosening and displacement of fusion cage and no obvious degeneration of adjacent segments. Conclusion:Anterior cervical discectomy and fusion combined with ROI-C application for the treatment of cervical spondylosis exhibits great therapeutic effects because it can greatly alleviate patient symptoms and improve cervical function.
