胸腔镜根治术对老年食管癌患者术后肺部感染与呼吸功能及炎症因子的影响

目的探讨胸腔镜根治术对老年食管癌患者术后肺部感染与呼吸功能及炎症因子的影响。方法选择100例行手术治疗的食管癌患者的临床资料进行回顾性分析,根据手术方法分为胸腔镜组60例与开胸组40例。比较2组术后肺功能、外周炎症因子水平以及肺部感染发生率。结果(1)2组术后24 h外周血炎症因子IL-6、IL-8、IL-10以及TNF-α均显著升高(P<0.05),但开胸组显著高于胸腔镜组(P<0.05);术后1周,2组外周血炎症因子水平均显著下降,2组间比较差异无统计学意义(P>0.05)。(2)术后1个月,开胸组患者FEV1、FEV1/FVC FVC均显著低于胸腔镜组,差异有统计学意义(P<0.05)。(3)术后3天开胸组CRP水平、WBC水平、体温以及呼吸频率均显著高于胸腔镜组,差异有统计学意义(P<0.05)。(4)胸腔镜组术后无肺部感染,开胸组有4例(10.0%)发生肺部感染,2组比较差异有统计学意义(P<0.05)。结论与传统开胸手术比较,胸腔镜食管癌根治术对老年患者呼吸功能、外周血炎症因子的影响相对较小,术后患者肺部感染发生率更低。     

Significant reduction of postoperative pain and opioid analgesics requirement with an Enhanced Recovery After Thoracic Surgery protocol

ObjectiveTo evaluate differences in postoperative pain control and opioids requirement in thoracic surgical patients following implementation of an Enhanced Recovery after Thoracic Surgery protocol with a comprehensive postoperative pain management strategy.Material and MethodsA retrospective analysis of a prospectively maintained database of patients undergoing pulmonary resections by robotic thoracoscopy or thoracotomy from January 1, 2017, to January 31, 2019, was conducted. Multimodal pain management strategy (opioid-sparing analgesics, infiltration of liposomal bupivacaine to intercostal spaces and surgical sites, and elimination of thoracic epidural analgesia use in thoracotomy patients) was implemented as part of Enhanced Recovery after Thoracic Surgery on February 1, 2018. Outcome metrics including patient-reported pain levels, in-hospital and postdischarge opioids use, postoperative complications, and length of stay were compared before and after protocol implementation.ResultsIn total, 310 robotic thoracoscopy and 62 thoracotomy patients met the inclusion criteria. This pain management strategy was associated with significant reduction of postoperative pain in both groups with an overall reduction of postoperative opioids requirement. Median in-hospital opioids use (morphine milligram equivalent per day) was reduced from 30 to 18.36 (P = .009) for the robotic thoracoscopy group and slightly increased from 15.48 to 21.0 (P = .27) in the thoracotomy group. More importantly, median postdischarge opioids prescribed (total morphine milligram equivalent) was significantly reduced from 480.0 to 150.0 (P < .001) and 887.5 to 150.0 (P < .001) for the thoracoscopy and thoracotomy groups, respectively. Similar short-term perioperative outcomes were observed in both groups before and following protocol implementation.ConclusionsImplementation of Enhanced Recovery after Thoracic Surgery allows safe elimination of epidural use, better pain control, and less postoperative opioids use, especially a drastic reduction of postdischarge opioid need, without adversely affecting outcomes.     

Transcervical approach with endoscopic assistance for surgical treatment of patient with irreducible atlantoaxial dislocation: a case report

We demonstrate the case of a surgery in a patient with irreducible atlantoaxial dislocation (IrAAD) after C2 fracture. The challenges of this case were the flexed head in a forced position, impossibility of neck extension, and revision operation after posterior occipito-cervical fixation. The patient underwent the following surgeries: 1. A ventral release of C1-C2 using transcervical endoscopy; 2. Removal of occipito-cervical system and fibrous block resection in the posterior surfaces of the C1-C2; 3. Reducing of AAD and odontoid screw fixation; 4. Posterior C1-C2-C3 screw fixation. Ankylosing of C1-C2 and C2-C3-C4 fusion was verified by computed tomography scan. There was an improvement in patient status as observed by the increase of the SF-36 scale scores.The use of endoscopic transcervical approach is a good alternative to the transoral approach. Comparative studies of these methods should be performed regarding the choice of an optimal method of decompression in cases of IrAAD.     

医学本科生在儿外科实习中的困惑和解决策略

实习是医生从理论步入实战最重要的经历。2014年国家七部委联合出台《意见》:进入临床工作的住院医师要求本科必须取得毕业证、规培证、执业证才有资格。也就是本科毕业后必须进行为期3年的规范化培训才有资格进入临床。这种教学模式对医学本科生实习心态波动很大。对是否考研,如何选择就业充满困惑,尤其是面对难度高、收入低、稀缺小专业或者不喜欢的专业,抵触、焦虑、逃避成了学生最常见反应。他们认为是浪费自己读书时间,耽误考研,以至于学生和代教教师在实际工作中普遍表现得敷衍、懈怠。如何改善现状和帮助学生走出困境,不仅需要医院深化教学改革,同时政府行为、政策也亟待完善或改革。     

Risk factors and management of stoma-related obstruction after laparoscopic colorectal surgery with diverting ileostomy

BackgroundStoma-related obstruction (SRO) is defined as small bowel obstruction occurring around the limbs of diverting ileostomy (DI). This study was aimed to investigate the incidence, risk factors, and management of SRO after laparoscopic colorectal surgery with DI creation.MethodsThis study included 155 patients who underwent laparoscopic colorectal surgery with DI creation for rectal cancer (n = 138), ulcerative colitis (UC) (n = 14), and familial adenomatous polyposis (FAP) (n = 3) between 2011 and 2019. Univariate and multivariate analyses were performed to identify the risk factors of SRO.ResultsThe incidence of SRO was 7.7% (n = 12), and it was significantly lower (P < 0.01) in patients with lower anterior resection or intersphincteric resection (4.3%) than in those with ileal-pouch anal anastomosis (IPAA) (35.2%). The multivariate analysis revealed that IPAA was independently associated with the development of SRO (P = 0.001; odds ratio, 9.4; 95% confidence interval, 2.5–35.4). Eleven of 12 patients (92%) with SRO required trans-stomal tube decompression, and 8 of those (67%) underwent early stoma closure.ConclusionIPAA was an independent risk factor of SRO in laparoscopic colorectal surgery with DI creation. Early stoma closure was needed in most cases of SRO.     

Antibiotic prophylaxis in orthognathic surgery: an overview of systematic reviews

The purpose of this overview was to assess different antibiotic regimens used in orthognathic surgery and to establish an evidence-based protocol so that beneficial and adverse effects can be determined. A comprehensive literature search for systematic reviews and/or meta-analyses was conducted in MEDLINE (PubMed), EMBASE, and the Cochrane Library until March 2020. Grey literature was investigated in Google Scholar, and a manual search was done of references lists. Two meta-analyses and four systematic reviews met the inclusion criteria. The AMSTAR-2-tool was used to ascertain the potential risk of bias in the included studies, which presented moderate to high methodological quality. Lower infection rates were associated with long-term therapies of penicillin, cefazolin-cephalexin, and amoxicillin-clavulanic-acid, with rates varying from 0% - 3.13%. Higher rates were reported in placebo groups (52.6%) and short-term penicillin therapy (60%). Side effects were reported with cefazolin, clindamycin, and penicillin therapies, including nausea, pain, swelling, headache, vomiting, and skin rash. Evidence suggests that long-term antibiotics can reduce the risk of a surgical site infection (SSI) in orthognathic surgery, but there is uncertainty regarding the effects of one dose of antibiotics preoperatively versus short-term antibiotics. In the same way, intravenous penicillin, cefazolin, clindamycin, and amoxicillin-clavulanic acid kept the infection rates associated with bimaxillary procedures under 3.5%.     

Effects of throat packs during orthognathic surgery: a double-blind randomized controlled clinical trial

Throat packs are commonly used in maxillofacial surgeries. However, the evidence to support the benefits of their use is controversial. The aim of this study was to evaluate the effectiveness of throat packs in preventing postoperative nausea and vomiting, and their influence on the incidence of sore throat and dysphagia in patients undergoing orthognathic surgery. This was a prospective double-blind randomized study with 54 patients, who were randomized to two groups: with throat pack (n = 27) and without throat pack (n = 27). Fifty patients (25 in each group) were included in the analysis; 66% female and 34% male, mean age 29.44 ± 8.53 years. Postoperative nausea and vomiting (Kortilla scale), sore throat (visual analogue scale), and dysphagia were evaluated. Statistically significant differences in favour of the without-pack group were found for the variables throat pain at 24 hours (P = 0.002) and dysphagia at 2 hours (P = 0.007) and 24 hours (P < 0.001). There was no difference between the groups regarding postoperative nausea and vomiting (P = 1.00). The results of this study indicate that throat packs as utilized here do not prevent postoperative nausea and vomiting and are associated with worse sore throats and postoperative dysphagia.     

Antibiotics in orthognathic surgery: a retrospective analysis and identification of risk factors for postoperative infection

This study was undertaken to evaluate the infection rate following orthognathic surgery and to identify possible risk factors. A retrospective study was conducted. Patients undergoing orthognathic surgery from August 1, 2017 to July 31, 2018 were included. The outcome variable was surgical site infection (SSI). All data were analysed with respect to demographics and procedure specifications. A total of 137 patients (mean age 28.5 ± 12.69 years) were included in this study, of whom 20 (14.6%) developed a SSI. The only risk factor identified was the type of surgery: those undergoing mandibular osteotomies (in bilateral sagittal split osteotomy (BSSO) or bimaxillary osteotomies) were far more likely to develop infections. Third molar teeth were removed during orthognathic surgery in 28.5% of the procedures, and a genioplasty was performed in 10.9%. Removal of osteosynthesis material because of infectious reasons was necessary in 10.2% of patients, with a strong association to previous SSI. In conclusion, this study showed an infection rate of 14.6% with no link to any demographic risk factor. Neither the simultaneous removal of third molar teeth nor genioplasty was found to be a risk factor for SSI. For literature comparison purposes, there is a clear need for the international guidelines defining SSI to be used.
