Objective:To evaluate the effect of ultrasound-guided adductor canal combined with knee joint posterior capsule space block on the recovery period delirium in elderly patients undergoing total knee arthroplasty (TKA).Methods:A total of 68 elderly patients who underwent unilateral TKA at the Nanjing First Hospital from December 2021 to December 2022 were selected. They were randomly divided into a control group ( n=34) and an observation group ( n=34) using a random number table method. Both groups received general anesthesia, and the observation group received ultrasound-guided myofascial tube combined with knee joint posterior capsule space block before the surgery began. The incidence of delirium within 24 hours after surgery was mainly observed in two groups of patients. The surgical time, recovery time, intraoperative blood loss, infusion volume, total use of propofol and remifentanil were recorded; The resting and motor Visual Analogue Scale (VAS) scores of the patient were recorded at 4, 8, and 24 hours postoperatively. The patient′s serum tumor necrosis factor-α (TNF-α) and melatonin levels were measured on the day before surgery, the evening after surgery, and the first day after surgery. The subjective sleep quality score was recorded on the first day after surgery; The total dosage of sufentanil for patient-controlled intravenous analgesia (PCIA) within 24 hours after surgery, the effective number of compressions (P1) and actual number of compressions (P2) of PCIA, and the number of cases of additional oxycodone analgesia were recorded; The occurrence of respiratory depression, excessive sedation, nausea, and vomiting within 24 hours after surgery was recorded; The occurrence of complications of nerve block in the observation group was recorded. Results:The incidence of delirium during the recovery period in the observation group was lower than that in the control group ( P<0.05). The dosage of propofol and remifentanil in the observation group was lower than that in the control group (all P<0.05), and the awakening time was shorter than that in the control group ( P<0.05). The VAS scores at rest and exercise at 4, 8, and 24 hours after surgery in the observation group were lower than those in the control group (all P<0.05). Compared with the day before surgery, the observation group showed an increase in melatonin levels on the night after surgery ( P<0.05) and an increase in TNF-α levels on the first day after surgery ( P<0.05); The control group had a decrease in melatonin levels on the first day after surgery ( P<0.05), and an increase in TNF-α levels on the night and day after surgery (all P<0.05). The serum melatonin levels in the observation group were higher than those in the control group on the evening and first day after surgery (all P<0.05), and TNF-α levels were lower than those in the control group (all P<0.05). The subjective sleep quality score of the observation group showed that the total dosage of PCIA sufentanil, P1, P2, and the number of cases of additional oxycodone analgesia within 24 hours after surgery were lower than those of the control group (all P<0.05). The incidence of nausea in the control group (13 cases, 38.2%) was higher than that in the observation group (3 cases, 8.8%) ( P<0.05). Conclusions:In elderly patients undergoing unilateral TKA under general anesthesia, preoperative use of ultrasound-guided adductor tube combined with knee joint posterior capsule space block can effectively reduce the occurrence of postoperative delirium.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

[Purpose]To analyze the compliance rates and influencing factors for gastroscopy and colonoscopy in gastrointestinal cancer screening,and to provide evidence and management recom-mendations for gastrointestinal cancer screening programs.[Methods]The study was based on the joint gastrointestinal cancer screening program conducted in Fenghua District of Ningbo City in 2023.The target population underwent risk assessments,following which high-risk individuals were mobilized for gastroscopy and colonoscopy screenings.The x2 test was used to compare the positive rates of gastrointestinal cancer risk assessments and the compliance rates of clinical screenings among populations with different characteristics.Multivariable Logistic regression models were applied to analyze the factors associated with compliance rates of clinical gastroscopy and colonoscopy screenings among high-risk individuals.[Results]A total of 48 587 individuals were included in the analysis,with an average age of(63.95±7.48)years old.Among them,39.45％(19 166 individuals)were male.The positive rates of risk assessment for upper gastrointestinal cancer and colorectal cancer were 39.00％(18 949 individuals)and 16.02％(7 782 individuals),respectively.The compliance rates for gastroscopy and colonoscopy were 59.51％(11 227/18 949)and 50.85％(3 957/7 782),respectively.Multivariable Logistic regression analysis revealed that unmarried in-dividuals and those with an assessment interval of more than 14 d had lower compliance with gas-troscopy(both P＜0.05).High-risk individuals for upper gastrointestinal cancer with BMI≥24 kg/m2,gastrointestinal symptoms,history of upper gastrointestinal diseases,family history of cancers,history of gastroscopy,lower intake of fresh vegetables and fruits,and higher intake of processed meats had higher compliance with gastroscopy(all P＜0.05).High educational levels and an assess-ment interval of more than 14 d were associated with lower compliance with colonoscopy(both P＜0.05).Among individuals at high risk for colorectal cancer,those with gastrointestinal symptoms,history of upper gastrointestinal diseases,higher intake of processed meats and fried or grilled foods,and a positive risk assessment for upper gastrointestinal cancer had higher compliance with colonoscopy(all P＜0.05).[Conclusion]Participants in the joint gastrointestinal cancer screening program exhibit high compliance with both gastroscopy and colonoscopy.Compliance with gas-troscopy and colonoscopy is associated with individual lifestyle,health conditions,disease history,medical history,and family history of cancers.

The pursuit of cosmetic effects in post-surgical wounds has led to the development of ultra-minimally invasive techniques in surgery. Minimal invasive surgery has replaced open surgery and has become the new gold-standard for treating diseases. One such technique is the single incision triangulated umbilicus surgery (SITUS), which offers several advantages over traditional laparoscopic and other scarless surgeries, including reduced trauma, faster recovery, and better cosmetic outcomes. SITUS also has a short learning curve, aligns with conventional instrumentation operating habits, and can be used for whole abdominal surgeries. Chinese scholars have made further improvements to the SITUS technology, including expanding its applicability in intra-abdominal surgery and refining its incision closure methods to achieve superior cosmetic results. Currently, SITUS technology is experiencing rapid development in urology applications and has demonstrated satisfactory results in both domestic and international reports. This review aims to discuss the effectiveness and development of the SITUS technique in urology.
