Objective To make a retrospective analysis on an early clinical outcome of total knee arthroplasty (TKA) for the knees with different degrees of flexion-contracture deformities. Methods Ninety-seven knees of 65 patients undergoing total knee arthroplasty with the Scorpio posterior-stabilized knee prosthesis from January 2000 to December 2003 were reviewed, including 51 osteoarthritis patients (74 knees) and 14 rheumatoid arthritis patients (23 knees). Thirtythree patients underwent unilateral TKA, and 32 patients underwent bilateral TKA. The average range of motion (ROM) before operation was 82.8°(range, 5-140°).According to the preoperative flexion-contracture degrees of the knees, these patients were divided into 2 groups, group A and group B. Group A consisted of the patients with flexioncontracture less than 20° (range, 0-15°), and group B consisted of the patients with flexion-contracture not less than 20° (range, 20-60°). In group A, the average flexion-contracture degree, ROM, KSS (knee society score), and function score were 10.7±8.0°, 104.6±20.0°, 29.1±18.0, and 32.6±20.7, respectively. But the corresponding data were much worse ingroup B than in group A, which were 28.2±7.8°, 60.8±26.6°, 12.1±13.2, and 26.8±18.1. All the operations were primary total knee arthroplasty, and they were performed by the same group of surgeons. The time for the prosthesis installed lasted for 25.6 minutes, and the average tourniquet time was 34.7 minutes. Three or four days after operation, the patients began the continuous passive motion (CPM) and active functional exercise of the knee.Results The patients were followed up for an average of 2 years and 7 months(range, 8 mon-3.5 yr). During the follow-up period, the average flexion-contracture degree, ROM, KSS, and function score in group A were 0.4±2.1°, 108.6±19.0°, 82.1±13.8, and 72.3±29.1, respectively; and the corresponding data in group B were 1.3±3.2°, 986±16.4°, 75.9±8.2, and 81.4±26.9, respectively. There was no significant difference between the 2 groups. No revision or deep infection was found. Conclusion The curative effect is mainly determined by the surgeon’s good operational skills, rich clinical experience, and familiarity with the prosthesis, and it is not influenced by severity of the knee flexioncontracture deformity. The knee ROM after TKA, which has a “toward middle ROM”phenomenon, is influenced by many clinical factors. It is very important for the patientto perform a functional exercise of the knee as early as possible after operation.
Objective To compare the clinical efficacy and safety of different surgical methods in the treatment of early-stage gallbladder carcinoma (GBC). Methods The clinical data of 43 patients with early-stage GBC who received treatment in Peking University People’s Hospital from Jan. 2010 to Dec. 2016 were retrospectively analyzed. According to the surgical methods, the patients were divided into laparoscopic cholecystectomy (LC)+lymph node dissection (LND)+radiofrequency ablation (RA) group, open cholecystectomy (OC)+LND+RA group, and OC+LND+liver resection (LA) group. Operation duration, intraoperative blood loss, postoperative hospital stay, surgical complications, and long-term survival were compared among the 3 groups. Results All the 43 patients performed successful surgery without perioperative death. ① Operation duration and postoperative hospital stay. The differences of operation duration and postoperative hospital stay among the 3 groups were statistically significant (P<0.05). Compared with the LC+LND+RA group, operation duration and postoperative hospital stay of the OC+LND+RA group and the OC+LND+LR group were longer (P<0.017), but there was no statistically significant difference between the OC+LND+RA group and the OC+LND+LR group (P>0.017). ② Intraoperative blood loss. The difference of intraoperative blood loss among the 3 groups was statistically significant (P<0.001). Compared with the OC+LND+LR group, the intraoperative blood loss was lower in the LC+LND+RA group and the OC+LND+RA group (P<0.017), but there was no significant difference between the LC+LND+RA group and the OC+LND+RA group (P=0.172). ③ Postoperative complications. There was no significant difference in the incidence of postoperative complications among the 3 groups (P=0.326). ④ Long-term survival. There was no significant difference in survival curves among the 3 groups (P=0.057). Conclusions The method of cholecystectomy combined with LND and RA of gallbladder bed can achieve the radical effect on early-stage GBC (Tis–T2). Laparoscopic surgery, in particular, has shorter operation duration and faster recovery.
Objective To explore the medium- and long-term clinical effects of procedure for prolapse and hemorrhoids (PPH) combined with Block operation for obstructed defecation syndrome (ODS). Methods Clinical data of 187 patients with ODS caused by rectocele (RE) who received PPH+Block operation or pure PPH operation in The Chaoyang City Central Hospital from Mar. 2011 to May. 2013, were collected retrospectively, in which 95 patients underwent PPH+Block operation (PPH+Block group) and 92 patients underwent PPH operation (PPH group). Compared the postoperative Longo’s score, postoperative clinical effect, operative effect, and recurrence rate between the 2 groups. Results ① The postoperative Longo’s score: the postoperative Longo’s scores of the PPH+Block group were both lower than those of the PPH group at 1- and 3-year after operation (P<0.05). ② Postoperative curative effect: the total effective rate of the PPH+Block group and the PPH group were both 100%, but the clinical effect of the the PPH+Block group was better than that of the PPH group (Z=–10.15, P<0.05). ③ Operative effect: there was no statistical significance on operative time, intraoperative blood loss, returned to normal activity time, hospital stay, and postoperative visual analogy score (VAS) between the 2 groups (P>0.05). In addition, there were no statistical significance on the incidences of urinary retention, hematochezia, exhaust anal incontinence, and anal fissure between the 2 groups (P>0.05), but the incidence of urgent or high anal straining feeling in the PPH+Block group was significantly higher than that of the PPH group (P<0.05). ④ Medium- and long-term recurrence rate: the recurrence rate of 1-year after operation was similar between these2 groups (P>0.05), but the recurrence rate of 3-year after operation in the PPH+Block group was significantly lower than that of the PPH group (P<0.05). Conclusions The medium clinical effect has no obvious difference between PPH+Block and PPH operation, but the long-term recurrence rate of the former is lower than that of the latter, and the medium- and long-term effect is stable in PPH+Block operation for ODS caused by RE.
Objective To compare right anterolateral minithoracotomy and traditional median sternotomy in the treatment of left atrial myxoma. Methods Forty-one patients with left atrial myxoma treated in our hospital from January 2009 to January 2018 were divided into two groups according to the operation method: a right anterolateral minithoracotomy group including 15 patients, with 7 males and 8 females, aged 45.1±15.4 years; a median sternotomy group including 26 patients, with 10 males and 16 females, aged 49.4±11.9 years. The clinical data of the two groups were compared. Results There was no significant difference in preoperative clinical data between the two groups. All patients completed the operation without perioperative death. There was no significant difference in the operation time, cardiopulmonary bypass time, aortic clamp time or the incidence of postoperative complications between the two groups. However, compared with the median sternotomy group, the right anterolateral minithoracotomy group had shorter duration of mechanical ventilation, ICU stay and postoperative hospital stay, and less volume of drainage and blood transfusion 24 hours after surgery (all P<0.05). After 3–106 months follow-up, no recurrence was observed in both groups. Conclusion Compared with traditional median sternotomy for left atrial myxoma resection, right anterolateral minithoracotomy is safe, effective and less traumatic. It can be used as a routine treatment for left atrial myxoma.
ObjectiveTo investigate the clinical effect and prognosis of laparoscopic complete mesocolic resection (CME) in the treatment of elderly patients with stage Ⅲ right colon cancer.MethodsClinical data of 280 elderly patients (aged 60 years or older) who underwent stage Ⅲ right hemicolectomy in the First Hospital of Lanzhou University from 2010 to 2015 were collected. Among them, 160 patients underwent laparoscopic CME treatment were set as the observation group, and 120 patients underwent conventional laparotomy were set as the control group. The mean operative time, intraoperative blood loss, postoperative first anal exhaust time, number of lymph nodes dissection, number of positive lymph nodes, length of hospital stay and postoperative complications were compared between the two groups. The postoperative local recurrence rate, distant metastasis rate, 3-year cumulative survival rate and postoperative recurrence risk factors were analyzed.ResultsThere were no statistically significant differences between the observation group and the control group in operative time, number of lymph node dissection, number of positive lymph nodes and postoperative distant metastasis rate (P>0.05). The amount of intraoperative blood loss, postoperative anal first exhaust time, days of hospitalization, and postoperative recurrence rate in the observation group were less or shorter or lower than those in the control group, with statistically significant differences (P<0.05). The 3-year survival rate in the observation group was higher than that in the control group (log-rank χ2 =11.865, P=0.001), and the disease free survival in the observation group was also higher than that in the control group (log-rank χ2=7.567, P=0.006). Logistic regression was used to analyze the cases of postoperative recurrence in the two groups, and it was found that the degree of tumor differentiation, vascular invasion and lymph node metastasis were independent risk factors for postoperative tumor recurrence.ConclusionLaparoscopic CME in the treatment of elderly patients with stage Ⅲ right colon cancer is effective, it is safe and feasible, which can effectively prolong the survival time of patients.
ObjectiveTo compare the clinical effect of laparoscopic Heller myotomy (LHM) combined with Dor fundoplication and peroral endoscopic myotomy (POEM) in treatment of patients with achalasia.MethodsThe clinical data of 67 patients with achalasia from January 2014 to December 2018 in the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. Among them, 19 patients received the LHM combined with Dor fundoplication (LHM group), 48 patients received the POEM (POEM group). The clinical efficacy and safety of the two groups were compared.ResultsThere were no significant differences in the baseline data such as the gender, age, course of disease, body mass index, preoperative Eckardt score, preoperative maximum diameter of esophagus, and previous treatment history between the two groups (P>0.05). There were no significant differences in the operation time, bleeding volume, the Eckardt points at 3 and 12 months after operation, the decrease degree of maximum diameter of esophagus, complications (except for gastroesophageal reflux, P=0.029), and recurrence rate between the two groups (P>0.05). The total hospitalization time, postoperative hospitalization time, and total hospitalization costs of the POEM group were lower than those of the LHM group (P<0.05).ConclusionsBoth LHM and POEM could effectively relieve clinical symptoms, short-term efficacy and safety of the two kinds of operations are similar. Postoperative recovery of POEM is fast and hospitalization cost is less, but incidence of gastroesophageal reflux is higher.
ObjectiveTo evaluate the clinical efficacy of preoperative intra-aortic balloon pump (IABP) insertion in patients with off-pump coronary artery bypass grafting (OPCABG) surgery.MethodsThe clinical data of 130 patients who underwent OPCABG with IABP from 2015 to 2019 in our hospital were retrospectively analyzed. The patients were divided into two groups, including a group A (preoperative IABP insertion, n=72) and a group B (emergent IABP insertion, n=58). There were 42 males and 30 females in the group A with an average age of 60-72 (65.0±5.2) years. There were 32 males and 26 females in the group B with an average age of 56-73 (62.3±7.6) years. The in-hospital mortality rate and prognosis were compared between the two groups.ResultsThe in-hospital mortality rate in the group A (4.2%) was significantly lower than that in the group B (12.1%, P=0.002). The IABP time (40.8±10.3 min vs. 65.3±15.6 min), mechanical ventilation time (18.7±6.1 min vs. 48.7±10.5 min) and ICU stay time (48.1±7.8 min vs. 90.2±21.3 min) of the group A were shorter than those of the group B (P<0.05). The number of bypass grafts was not significantly different between the two groups (3.6±1.2 vs. 3.8±1.0, P=0.387). Multivariable logistic regression analysis indicated that independent risk factors for in-hospital mortality included age [OR=1.04, 95%CI (1.01, 1.10), P=0.030], female [OR=2.56, 95%CI (1.53, 6.12), P=0.000] and left ventricular end-diastolic diameter [OR=1.05, 95%CI (1.01, 1.13), P=0.030]. Preoperative IABP support was the protective factor [OR=0.17, 95%CI (0.01, 0.78), P=0.005].ConclusionPatients undergoing OPCABG with preoperative IABP insertion may reduce in-hospital mortality rate and improve outcomes.
Objective To explore the clinical effects of emergency transcatheter aortic replacement (TAVR) on the treatment of patients with acute refractory heart failure or cardiogenic shock secondary to severe aortic stenosis during hospitalization. Methods The study selected 44 patients from 8 heart valve centers from January 2018 to January 2021. All patients received emergency TAVR treatment. The patients’ baseline clinical data, cardiac ultrasound indicators, and postoperative hospital stay were collected. Paired t-test and McNemar test were used to compare and analyze the preoperative and postoperative cardiac ultrasound indexes, moderate to severe aortic stenosis, and cardiac function. Results The average age of the patients was (72.0±7.9) years. Valve displacement occurred in one patient during the operation, and the surgical success rate was 97.7%. Four cases died during hospitalization, and the mortality rate was 9.1%. The median length of hospital stay was 11.5 d. The postoperative aortic valve area was significantly higher than that before surgery [(0.5±0.2) vs. (3.8±1.6) mm2, P<0.05], the mean transvalvular pressure of the aortic valve was significantly lower than that before operation [(64.0±24.9) vs. (11.3±4.6) mm Hg (1 mm Hg=0.133 kPa), P<0.05], the peak aortic flow velocity was significantly lower than that before operation [(4.5±0.7) vs. (1.9±0.7) m/s, P<0.05], the left ventricular end diastolic inner diameter was lower than that before operation [(59.0±7.2) vs. (56.1±7.3) mm, P<0.05], the left ventricular ejection fraction increased significantly compared with that before operation [(30.1±10.4)% vs. (40.9±11.0)%, P<0.05], and the cardiac function improved significantly compared with that before operation (P<0.05). During the operation, 2 cases (4.5%) underwent valve-in-valve implantation, 11 cases (25.0%) underwent percutaneous coronary intervention during the same period. During the postoperative hospital stay, 1 case (2.3%) developed stroke, 3 cases (6.8%) experienced severe bleeding, 5 cases (11.4%) had severe vascular complications, 2 cases (4.5%) experienced acute myocardial infarction, 30 cases (68.2%) had small or trace paravalvular regurgitation, 3 cases (6.8%) received permanent pacemaker implantation, and 5 cases (11.4%) developed acute kidney injury. Conclustion Emergency TAVR is an effective and feasible treatment plan for patients with acute refractory heart failure or cardiogenic shock secondary to severe aortic stenosis.
Objective To analyze the clinical effect of TINAVI robotic system-assisted pedicle screw internal fixation for thoracolumbar fracture with a Thoracolumbar Injury Classification and Severity Score (TLICS) of 4. Methods A total of 38 patients with TLICS 4 thoracolumbar fracture treated between January 2019 and January 2021 who met the selection criteria of Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital were retrospectively analyzed. According to the results of doctor-patient communication, 18 cases were treated with robot-assisted minimally invasive surgery (robot group), and 20 cases were treated with traditional conservative treatment (non-surgical group). Complications during hospitalization were observed. After discharge, the patients in the two groups were followed up by telephone and outpatient clinic. The Visual Analogue Scale (VAS) score at admission, at discharge, and 3 and 6 months after discharge, and the Oswestry Disability Index (ODI) score 3 and 6 months after discharge were compared between the two groups. Results There were no statistically significant difference in age, sex, body mass index or distribution of injured vertebrae segment between the two groups (P>0.05). No serious complication occurred in any group during hospitalization. The difference in the length of hospital stay between the two groups was not statistically significant (P>0.05). The bed rest in the robot group was shorter than that in the non-surgical group [(4.83±0.92) vs. (43.05±2.70) d, P<0.05]. The VAS scores at discharge (2.50±0.51 vs. 5.05±1.00), 3 months after discharge (1.83±0.71 vs. 3.10±0.72) and 6 months after discharge (1.50±0.51 vs. 1.90±0.79) in the robot group were lower than those in the non-surgical group (P<0.05). The ODI scores 3 months after discharge (21.89±1.41 vs. 30.40±3.00) and 6 months after discharge (10.72±2.37 vs. 12.10±2.29) in the robot group were significantly lower than those in the non-surgical group (P<0.05). Conclusion For patients with TLICS 4 thoracolumbar fracture, the early clinical effect of robot-assisted surgical treatment is better than that of non-surgical treatment.
Sedation and analgesia techniques are widely used in endoscopic diagnosis and treatment. The main purpose is to relieve the anxiety and pain of patients and reduce the risk of complications. Esketamine has obvious advantages in the clinical application of sedative and analgesic endoscopy. For example, it has strong sedative and analgesic efficacy, slight influence on respiratory circulation with its sympathomimetic properties, rapid recovery, improved postoperative cognitive function, and fewer adverse reactions. However, due to the dose-dependent side effects of esketamine, it is necessary to pay attention to adverse reactions such as increased drainage, psychotropic symptoms, nausea and vomiting, and vertigo. This article summarizes the clinical effect of esketamine, the selection of drug dosage and the research progress of clinical application in special population during diagnosis and treatment of digestive endoscopy, respiratory endoscopy and gynecological endoscopy, in order to provide a reference for clinical research and drug guidance.
