Background: The history of surgical reconstruction of the left ventricle after an anterior myocardial infarction shows an evolution of techniques which tend to a more and more physiologic restoration of ventricular shape and volume, with increasing attention to the orientation of myocardial fibers.

Methods: We set a new surgical procedure for endoventricular patch reconstruction technique with the aim to rebuild a physiologic shape and volume of the left ventricle caring about realignment of myocardial fibers orientation. Peculiarities of this reconstruction are the shape of the patch (reduction of minor axis compared with currently used oval-shaped patch) and the asymmetrical way of suturing it inside the ventricle.

Results: We present a detailed description of operative steps of this procedure, and we add some relevant surgical hints to clarify its peculiarities. Most of the patients operated on with this technique showed the original renewal of apical rotation and left ventricular torsion as specific index of the restoration of physiologic fiber orientation: we report an exemplary case of at-sight recovery of apical rotation in the operating room.

Conclusion: This technique can represent a reproducible new way to realign myocardial fibers in a near-normal setting, improving the physiological restoration of ischemically injured left ventricle. It could be also the basis to reconsider surgical treatment for heart failure.

背景:前壁心肌梗死后左心室手术重建的历史表明,技术的发展越来越趋向于生理性地恢复心室的形状和容积,并越来越关注心肌纤维的方向:我们为心室内膜补片重建技术制定了一种新的手术方法,目的是重建左心室的生理形状和容积,同时关注心肌纤维方向的重新调整。这种重建技术的特点是补片的形状(与目前使用的椭圆形补片相比,缩小了小轴)和在心室内部的非对称缝合方式:我们详细介绍了这种手术的操作步骤,并补充了一些相关的手术提示,以阐明其特殊性。大多数使用该技术进行手术的患者都显示心尖旋转和左心室扭转恢复如初,这是恢复生理纤维方向的具体指标:我们报告了一例在手术室亲眼看到心尖旋转恢复的典型病例:结论:这项技术是在接近正常的情况下重新调整心肌纤维的一种可重复的新方法,可改善缺血性损伤左心室的生理恢复。它也可以作为重新考虑心力衰竭手术治疗的基础。

Background: The treatment of forearm fracture-nonunions continues to represent a therapeutic challenge, and reported outcomes are moderate at best. Limiting aspects of this particular anatomic location include the relation between restoration of shaft length with the anatomy and long-term functional outcome of adjacent joints, as well as the risk of elbow and wrist stiffness related to prolonged immobilization. The present study was designed to assess the outcome of autologous bone grafting with compression plating and early functional rehabilitation in patients with forearm fracture non-unions.

Methods: Prospective follow-up study in 31 consecutive patients presenting with non-unions of the forearm diaphysis (radius, n = 11; ulna, n = 9; both bones, n = 11). Surgical revision was performed by restoring anatomic forearm length by autologous bone grafting of the resected non-union from the iliac crest and compression plating using a 3.5 mm dynamic compression plate (DCP) or limited-contact DCP (LC-DCP). The main outcome parameters consisted of radiographic bony union and functional outcome, as determined by the criteria defined by Harald Tscherne in 1978. Patients were routinely followed on a short term between 6 weeks to 6 months, with an average long-term follow-up of 3.6 years (range 2 to 6 years).

Results: Radiographically, a bony union was achieved in 30/31 patients within a mean time of 3.5 months of revision surgery (range 2 to 5 months). Clinically, 29/31 patients showed a good functional outcome, according to the Tscherne criteria, and 26/31 patients were able to resume their previous work. Two postoperative infections occurred, and one patient developed a persistent infected nonunion. No case of postoperative failure of fixation was seen in the entire cohort.

Conclusion: Revision osteosynthesis of forearm nonunions by autologous iliac crest bone grafting and compression plating represents a safe and efficacious modality for the treatment of these challenging conditions.

背景:前臂骨折不连的治疗仍然是一个治疗挑战,报道的结果充其量是中等。这种特殊解剖位置的局限性包括骨轴长度的恢复与解剖结构和相邻关节的长期功能结果之间的关系,以及与长时间固定相关的肘关节和手腕僵硬的风险。本研究旨在评估前臂骨折不愈合患者采用加压钢板自体骨移植和早期功能康复的结果。方法:对31例连续出现前臂骨干不连(桡骨,n = 11;尺骨,n = 9;两根骨头,n = 11)。手术翻修通过髂骨自体骨移植恢复解剖前臂长度,并使用3.5 mm动态加压钢板(DCP)或有限接触加压钢板(LC-DCP)加压钢板。根据Harald Tscherne在1978年定义的标准,主要预后参数包括影像学骨愈合和功能预后。对患者进行6周到6个月的短期常规随访,平均长期随访3.6年(2至6年)。结果:在影像学上,30/31例患者在平均3.5个月的翻修手术时间(2至5个月)内实现骨愈合。临床中,29/31的患者表现出良好的功能结果,根据Tscherne标准,26/31的患者能够恢复之前的工作。术后发生2例感染,1例患者出现持续性感染不愈合。在整个队列中未见术后固定失败的病例。结论:自体髂骨植骨加压钢板修复前臂骨不连是一种安全有效的治疗方法。

Small bowel contractility may be more prominent in obese subjects, such that there is enhanced nutrient absorption and hunger stimulation. However, there is little evidence to support this. This study examined in vitro small bowel contractility in obese patients versus non-obese patients. Samples of histologically normal small bowel were obtained at laparoscopic Roux-en-Y gastric bypass from obese patients. Control specimens were taken from non-obese patients undergoing small bowel resection for benign disease or formation of an ileal pouch-anal anastomosis. Samples were transported in a pre-oxygenated Krebs solution. Microdissected circular smooth muscle strips were suspended under 1 g of tension in organ baths containing Krebs solution oxygenated with 95% O2/5% CO2 at 37 degrees C. Contractile activity was recorded using isometric transducers at baseline and in response to receptor-mediated contractility using prostaglandin F2a, a nitric oxide donor and substance P under both equivocal and non-adrenergic, non-cholinergic conditions (guanethidine and atropine). Following equilibration, the initial response to the cholinergic agonist carbachol (0.1 mmol/L) was significantly increased in the obese group (n = 63) versus the lean group (n = 61) with a mean maximum response: weight ratio of 4.58 +/- 0.89 vs 3.53 +/- 0.74; (p = 0.032). Following washout and re-calibration, cumulative application of substance P and prostaglandin F2a produced concentration-dependent contractions of human small bowel smooth muscle strips. Contractile responses of obese small bowel under equivocal conditions were significantly increased compared with non-obese small bowel (p < 0.05 for all agonists). However, no significant differences were shown between the groups when the experiments were performed under NANC conditions. There were no significant differences found between the groups when challenged with nitric oxide, under either equivocal or NANC conditions. Stimulated human small bowel contractility is increased in obese patients suggesting faster enteric emptying and more rapid intestinal transit. This may translate into enhanced appetite and reduced satiety.

肥胖受试者的小肠收缩可能更为突出,从而增强营养吸收和饥饿感刺激。然而,几乎没有证据支持这一观点。这项研究检查了肥胖患者与非肥胖患者的体外小肠收缩性。在腹腔镜Roux-en-Y胃旁路术中从肥胖患者获得组织学正常的小肠样本。对照标本取自因良性疾病或形成回肠袋-肛门吻合术而行小肠切除术的非肥胖患者。样品在预充氧的克雷布斯溶液中运输。将微解剖的圆形平滑肌条在1 g张力下悬浮于含有95% O2/5% CO2的克雷布斯溶液的器官液中,温度为37℃。在基线时使用等长传感器记录收缩活性,并在模糊和非肾上腺素能、非胆碱能条件下(胍乙啶和阿托品)使用前列腺素F2a、一氧化氮供体和P物质响应受体介导的收缩活性。平衡后,肥胖组(n = 63)对胆碱能激动剂carbachol (0.1 mmol/L)的初始反应显著高于瘦组(n = 61),平均最大反应:体重比为4.58 +/- 0.89 vs 3.53 +/- 0.74;(p = 0.032)。在洗脱和重新校准后,P物质和前列腺素F2a的累积应用产生了人小肠平滑肌条的浓度依赖性收缩。与非肥胖小肠相比,肥胖小肠在模棱两可条件下的收缩反应显著增加(所有激动剂均p < 0.05)。然而,当实验在NANC条件下进行时,各组之间没有显着差异。在模棱两可或NANC条件下,两组之间在一氧化氮刺激下没有发现显著差异。肥胖患者受刺激的小肠收缩力增加,提示肠道排空更快,肠道运输更快。这可能会导致食欲增强和饱腹感降低。

The etiology and prevention of feeding intolerance paralytic ileus--revisiting an old concept. 喂养不耐受性麻痹性回肠炎的病因和预防--重新审视一个古老的概念。

Gastro-intestinal (G-I) motility is impaired ("paralytic ileus") after abdominal surgery. Premature feeding attempts delay recovery by inducing "feeding intolerance," especially abdominal distention that compromises respiration. Controlled studies (e.g., from Sloan-Kettering Memorial Hospital) have lead to recommendations that patients not be fed soon after major abdominal surgery to avoid this complication. We postulate that when total fluid inflow of feedings, digestive secretions, and swallowed air outstrip peristaltic outflow from the feeding site, fluid accumulates. This localized stagnation triggers G-I vagal reflexes that further slow the already sluggish gut, leading to generalized abdominal distention. Similarly, vagal cardiovascular reflexes in susceptible subjects could account for the 1:1,000 incidence of unexplained bowel necrosis reported with enteral feeding. We re-evaluated our data, which supports this postulated mechanism for the induction of "feeding intolerance." We had focused our efforts on postoperative enteral nutrition, with the largest reported series of immediate feeding of at least 100 kcal/hour after major surgery. We found that this complication can be avoided consistently by monitoring inflow versus peristaltic outflow, immediately removing any potential excess from the feeding site. We fed intraduodenally immediately following "open" surgery for 31 colectomy and 160 consecutive cholecystectomy patients. The duodenum was aspirated simultaneously just proximal to the feeding site, efficiently removing all swallowed air and excess feedings. To salvage digestive secretions, the degassed aspirate was re-introduced manually (and later automatically) via a separate feeding channel. Hourly assays were performed for nitrogen balance, serum amino acids, and for the presence of removed feedings in the aspirate. The colectomy patients had X-ray motility studies initiated 5-17 hours after surgery. Clinically normal motility and absorption resumed within two hours. Fed BaSO4 traversed secure anastomoses, to exit in bowel movements within 24-48 hours of colectomy. All patients were in positive protein balance within 2-24 hours, with elevated serum amino acids levels and without adverse G-I effects. Limiting inflow to match peristaltic outflow from the feeding site consistently prevented "feeding intolerance." These patients received immediate full enteral nutrition, with the most rapid resolution of postoperative paralytic ileus, to date.

腹部手术后胃肠道(G-I)蠕动受损("麻痹性回肠")。过早尝试进食会诱发 "进食不耐受",尤其是腹胀影响呼吸,从而延迟康复。对照研究(如斯隆-凯特琳纪念医院的研究)建议患者在腹部大手术后不要马上进食,以避免出现这种并发症。我们推测,当进食、消化道分泌物和吞咽空气的总液体流入量超过进食部位的蠕动流出量时,液体就会积聚。这种局部淤积会触发 G-I 迷走神经反射,进一步减缓本已迟缓的肠道蠕动,导致腹部普遍胀气。同样,易感人群的迷走神经心血管反射也可能是肠道喂养导致 1:1,000 的不明原因肠坏死发生率的原因。我们重新评估了我们的数据,这些数据支持这种诱发 "进食不耐受 "的假定机制。我们将工作重点放在术后肠内营养上,大手术后每小时立即喂食至少 100 千卡热量的报道系列最多。我们发现,通过监测流入量和蠕动流出量,立即从进食部位清除任何可能多余的食物,可以持续避免这种并发症。我们对 31 例结肠切除术和 160 例胆囊切除术患者进行 "开放 "手术后立即进行十二指肠内喂食。同时在进食部位近端抽吸十二指肠,有效清除所有吞咽的空气和多余的进食物。为了挽救消化道分泌物,人工(后来是自动)通过单独的进食通道将脱气后的吸液重新导入。每小时检测一次氮平衡、血清氨基酸以及吸出物中是否有被清除的进食物。结肠切除术患者在术后 5-17 小时开始进行 X 射线运动研究。临床上,患者的运动和吸收在两小时内恢复正常。喂食的硫酸钡穿过安全的吻合口,在结肠切除术后 24-48 小时内排出肠道。所有患者均在 2-24 小时内达到正蛋白平衡,血清氨基酸水平升高,且无 G-I 不良反应。限制肠道流入量,使其与进食部位的蠕动流出量相匹配,可以有效防止 "进食不耐受"。这些患者立即得到了全面的肠内营养,术后麻痹性回肠炎得到了迄今为止最迅速的缓解。

Background: Positron emission tomography (PET) identifies cancer deposits by detecting sites of gamma emissions that are released from radioactively labeled molecules targeting tumor to formulate a PET image. Correlating preoperative PET scans with intraoperative findings remains a challenge. We investigated whether high-energy gamma emissions detected by a novel hand-held PET probe would detect tumors and offer a real-time method to localize tumor intraoperatively. Furthermore, we investigated the novel beta probe, which detects emissions at a shorter range than gamma emissions, making them undetectable by PET scanners, but potentially valuable for close range intraoperative detection of tumor deposits.

Methods: Six-to-eight-week-old athymic mice were injected with one of four possible tumor cell lines: gastric, pancreas, squamous cell and breast cancer. After tumors reached at least 1 cm in size, they were euthanized and imaged with a micro-PET imager. Hand-held gamma and beta probes were then used in vivo and ex vivo to measure high-energy gamma and beta emissions.

Results: The portable PET probes detected high-energy gamma and beta emissions from all tumors evaluated. These emissions were reproducible and we established that beta emissions correlate with high-energy gamma emissions and conventional PET scans. There was a strong positive correlation (R = 0.8) between gamma and beta counts. Beta emission showed a stronger correlation than gamma emission with overall tissue radioactivity.

Conclusion: This study is the first to demonstrate that gamma emission detected by conventional PET imaging correlates with beta emissions. This study shows that compared to detection of gamma emissions, beta counts may offer superior real-time localization of tumor deposits. Intraoperative portable PET probe may become a useful way to exploit tumor biology and PET technology to guide real-time tissue characterization during surgery.

背景:正电子发射断层扫描(PET)通过检测靶向肿瘤的放射性标记分子释放的伽马射线来识别癌症沉积物,从而形成PET图像。将术前PET扫描与术中发现相关联仍然是一个挑战。我们研究了一种新型手持式PET探针检测的高能伽马射线是否能检测出肿瘤,并为术中肿瘤定位提供了一种实时方法。此外,我们研究了新型的β探针,它可以探测到比伽马发射更短的距离,使其无法被PET扫描仪检测到,但对于术中肿瘤沉积物的近距离检测具有潜在的价值。方法:给6 ~ 8周大的胸腺小鼠注射四种可能的肿瘤细胞系之一:胃癌、胰腺癌、鳞状细胞癌和乳腺癌。当肿瘤达到至少1厘米大小时,对它们实施安乐死,并用微型pet成像仪成像。然后在体内和离体中使用手持伽马和β探针来测量高能伽马和β辐射。结果:便携式PET探针检测到所有评估肿瘤的高能γ和β辐射。这些辐射是可重复的,我们确定β辐射与高能伽马辐射和传统的PET扫描相关。γ计数和β计数之间有很强的正相关(R = 0.8)。β辐射比γ辐射与整体组织放射性的相关性更强。结论:本研究首次证明了常规PET成像检测到的伽马辐射与β辐射相关。这项研究表明,与伽马辐射检测相比,β计数可能提供更好的肿瘤沉积物实时定位。术中便携式PET探针可能成为利用肿瘤生物学和PET技术指导术中实时组织表征的有效途径。

Introduction: Gastro-oesophageal reflux disease (GORD) is a common problem in the Western countries, and the interest in the minimal access surgical approaches to treat GORD is increasing. In this study, we would like to discuss the presentations and management of complications we encountered after Laparoscopic Nissen's fundoplication in our District General NHS Hospital. The aim is to recognise these complications at the earliest stage for effective management to minimise the morbidity and mortality.

Methods: 301 patients underwent laparoscopic treatment for GORD by a single consultant surgeon in our NHS Trust from September 1999. The data was prospectively collected and entered into a database. The data was retrospectively analysed for presentations for complications and their management.

Results: Surgery was completed laparoscopically in all patients, except in five, where the operation was technically difficult due to pre-existing conditions. The complications we encountered during surgery and follow-up period were major intra-operative bleeding (n = 1, 0.33%), severe post-operative nausea and vomiting (n = 1, 0.33%), wound infection (n = 3, 1%), port-site herniation (n = 1, 0.33%), wrap-migration (n = 2, 0.66%), wrap-ischaemia (n = 1, 0.33%), recurrent regurgitation (n = 4, 1.32%), recurrent heartburn (n = 29, 9.63%), tension pneumothorax (n = 2, 0.66%), surgical emphysema (n = 8, 2.66%), and port-site pain (n = 4, 1.33%).

Conclusion: Minimal access approach to treat GORD has presented with some specific and unique complications. It is important to recognise these complications at the earliest possible stage as some of these patients may present in an acute setting requiring emergency surgery. All members of the department, and not just the members of the specialised team, should be aware about these complications to minimise the morbidity and mortality.

胃食管反流病(GORD)在西方国家是一个常见的问题,并且对最小通道手术入路治疗GORD的兴趣正在增加。在本研究中,我们将讨论在我们的地区综合NHS医院腹腔镜尼森手术后遇到的并发症的表现和处理。目的是在早期阶段识别这些并发症,进行有效的管理,以尽量减少发病率和死亡率。方法:自1999年9月起,301例患者接受腹腔镜下GORD治疗,由单一顾问外科医生在我们的NHS信托。前瞻性地收集数据并输入数据库。回顾性分析并发症的表现及其处理。结果:所有患者均在腹腔镜下完成手术,除了5例患者,由于先前存在的疾病,手术在技术上存在困难。我们手术和后续期间遇到的并发症是主要的术中出血(n = 1, 0.33%)、严重术后恶心和呕吐(n = 1, 0.33%),伤口感染(n = 3, 1%),切口疝(n = 1, 0.33%), wrap-migration (n = 2, 0.66%), wrap-ischaemia (n = 1, 0.33%),复发性返流(n = 4, 1.32%)复发胃灼热(n = 29, 9.63%),张力性气胸(n = 2, 0.66%),手术肺气肿(n = 8 2.66%),和切口疼痛(n = 4, 1.33%)。结论:微创入路治疗GORD有一些特殊和独特的并发症。重要的是要尽早认识到这些并发症,因为其中一些患者可能出现在需要紧急手术的急性环境中。科室的所有成员,而不仅仅是专业小组的成员,都应该了解这些并发症,以尽量减少发病率和死亡率。

Pub Date : 2008-11-28 DOI: 10.1186/1750-1164-2-5
Pravin J Gupta, Surekha Kalaskar

Objective: The aim of this study is to clinically test the efficacy of author's approach of suture ligation and mucopexy for patients having symptomatic and prolapsing hemorrhoids.

Materials and methods: 616 patients (255 females) complaining of symptoms of hemorrhoids were included in the study. The hemorrhoids were suture ligated with an absorbable suture material under vision. Operating time, postoperative complications, time to return to work, and outcome of the procedure were analyzed. Follow-up was planned following discharge after 1 month, 6 months and after at least 1 year. Patient satisfaction was also assessed.

Results: The mean procedure time was 8 +/- 0 minutes (range, 6-15 minutes), and the total admission period was 12 +/- 4 Hours. Perianal thrombosis and skin tags were the commonest post-operative complications. The mean total analgesic dose and duration of pain control using analgesics was 19 +/- 4 tablets, and 9 +/- 3 days respectively.The postoperative follow up after 4 weeks revealed therapeutic success in 589 patients (95.6%), who presented with hemorrhoidal bleeding. Prolapse was no longer observed in 98% of patients and 96% patients experienced no pain after defecation. 93% patients completed the one-year follow-up and 89 percent of them were asymptomatic. The patient satisfaction scoring was 8.2% on visual analogue scale.

Conclusion: Suture ligation and mucopexy of hemorrhoids is an easy-to-perform technique that is well accepted by patients and has good results for prolapsing hemorrhoids.

Computed tomography of the shoulders in patients with obstetric brachial plexus injuries: a retrospective study. 产科臂丛损伤患者肩部的计算机断层扫描:一项回顾性研究。
Pub Date : 2008-11-07 DOI: 10.1186/1750-1164-2-4

Background: Scapular hypoplasia, elevation, and rotation (SHEAR) deformity and posterior subluxation of the humeral head are common tertiary sequelae of obstetric brachial plexus injuries (OBPI). Interpretations of images from bilateral computed tomography (CT) scans of the upper extremities are critical to the diagnosis and treatment plan for patients with these bony deformities resulting from OBPI.

Methods: We conducted a retrospective study to investigate the accuracy of radiologic reports in the diagnosis of SHEAR or posterior subluxation of the humeral head in OBPI patients. CT studies from 43 consecutive patients over a 33-month period were used in the study. For each patient, we compared the results from the radiologic report to those from a clinical examination given by the attending surgeon and to measurements taken from the CT studies by biomedical researchers.

Results: A comparison of SHEAR measured from the 3-D CT images to the diagnoses from the radiologists, revealed that only 40% of the radiological reports were accurate. However, there was a direct correlation between the use of the 3-D CT images and an accurate SHEAR diagnosis by the radiologists (p < 0.0001). When posterior subluxation was measured in the affected and contralateral shoulders, 93% of the patients that had greater than a 10% difference between the two shoulders did not have their deformity diagnosed. The radiological reports diagnosed 17% of these patients with a 'normal' shoulder. Only 5% of the reports were complete, accurately diagnosing SHEAR in addition to posterior subluxation.

Conclusion: Due to the low incidence rate of OBPI, many radiologists may be unfamiliar with the sequelae of these injuries. It is therefore critical that radiologists are made aware of the importance of an accurate measurement and diagnosis of the SHEAR deformity. Due to their lack of completeness, the radiological reports in this study did not significantly contribute to the clinical care of the patients. In order for OBPI patients to receive the highest standard of care, the final diagnosis from their radiological imaging should be deferred to a brachial plexus specialist who is experienced with these types of injuries.

背景:肩胛骨发育不全、抬高和旋转(SHEAR)畸形和肱骨后侧半脱位是产科臂丛神经损伤(OBPI)常见的第三期后遗症。上肢双侧计算机断层扫描(CT)图像的解释对于由OBPI引起的这些骨畸形患者的诊断和治疗计划至关重要。方法:我们进行了一项回顾性研究,探讨放射学报告在诊断肱骨头后方半脱位或肱骨头后方半脱位时的准确性。研究中使用了连续33个月的43例患者的CT研究。对于每位患者,我们将放射学报告的结果与主治医生提供的临床检查结果以及生物医学研究人员从CT研究中获得的测量结果进行比较。结果:将三维CT图像测量的SHEAR与放射科医生的诊断进行比较,发现只有40%的放射报告是准确的。然而,三维CT图像的使用与放射科医生对切变的准确诊断之间存在直接相关性(p < 0.0001)。当测量受累肩部和对侧肩部的后半脱位时,93%的两肩差异大于10%的患者没有诊断出畸形。放射学报告诊断17%的患者肩关节“正常”。只有5%的报告是完整的,准确地诊断出SHEAR和后路半脱位。结论:由于OBPI的发生率较低,许多放射科医生可能对这些损伤的后遗症不熟悉。因此,让放射科医生意识到准确测量和诊断SHEAR畸形的重要性是至关重要的。由于缺乏完整性,本研究的放射学报告对患者的临床护理没有显著的帮助。为了使OBPI患者获得最高标准的护理,放射成像的最终诊断应推迟给对这类损伤有经验的臂丛神经专家。

Background: Esophagogastric fistula following an esophagectomy for cancer is very common. One of the most important factors that leads to its development is gastric ischemia. We hypothesize that laparoscopic gastric devascularization and partial transection is a safe operation that will enhance the vascular flow of the fundus of the stomach.

Method: Our study included eight pigs. Each animal had two operations. In the first one, a laparoscopic gastric devascularization and mobilization took place. Vascular flow was measured previous to the procedure and immediately after it with a laser doppler (endoscopic probe). After three weeks, a second operation took place. We re-measured the vascular flow and sent a sample of gastric fundus for histopathologic evaluation.

Results: The gastric fundus showed signs of neovascularization after both macroscopic and microscopic evaluation. These findings correlated with laser doppler measurements.

Conclusion: Laparoscopic gastric devascularization and partial transection is a safe procedure that increases the vascular flow of the stomach in a three week period. This finding can have a positive impact in terms of decreasing fistula formation.

背景:食管癌术后发生食管胃瘘是非常常见的。胃缺血是导致其发生的重要因素之一。我们假设腹腔镜胃断流术和部分横断术是一种安全的手术,可以增强胃底的血管流动。方法:以8头猪为研究对象。每只动物都做了两次手术。在第一例中,进行了腹腔镜胃断流术和动员。在手术前和手术后立即用激光多普勒(内窥镜探头)测量血管流量。三周后,又进行了第二次手术。我们重新测量血管流量,并送胃底样本进行组织病理学评估。结果:胃底经肉眼和显微镜检查均有新生血管的征象。这些发现与激光多普勒测量结果相关。结论:腹腔镜胃断流术和部分横断术是一种安全的手术,可以在三周内增加胃的血管流量。这一发现在减少瘘管形成方面具有积极的影响。

Safety of carboxymethylcellulose/polyethylene oxide for the prevention of adhesions in lumbar disc herniation--consecutive case series review. 羧甲基纤维素/聚环氧乙烷用于预防腰椎间盘突出症粘连的安全性--连续病例系列回顾。
Pub Date : 2008-05-30 DOI: 10.1186/1750-1164-2-2

Background: Epidural fibrosis is regarded as a cause of failed back surgery syndrome (FBSS) when excessive adhesional/fibrotic scar tissue causes compression, pain or discomfort by tethering of nerve tissue to the surrounding muscle or bone. Fibrosis inhibitors could therefore increase the success rate of spinal surgery and decrease the need for reoperations. In recent years, bio-resorbable gels or films for the prevention of peridural fibrosis and post-operative adhesions have been developed that look clinically promising. This included a 100% synthetic, sterile, absorbable gel combinations of carboxymethylcellulose (CMC) and polyethylene oxide (PEO) used to coat the dura to reduce scarring after discectomy which became available in Europe in 2002. However, given the burden of the problem and unfavorable experience with other types of adhesion-reduction agents, our unit decided to evaluate the safety of CMC/PEO in a large population of patients undergoing spinal microdiscectomy for herniation.

Methods: To determine the safety and assess efficacy of carboxymethylcellulose/polyethylene oxide (CMC/PEO) gel as an anti-adhesion gel, a consecutive series of 396 patients undergoing lumbar discectomy performed by one surgeon had CMC/PEO gel administered at the end of surgery. The patients were followed up in accordance with standard clinical practice and records reviewed for side effects, such as skin reactions, general reactions or local fluid collections. Reoperations for recurrent herniation included an evaluation of fibrosis reduction.

Results: No product related complications were observed. Five patients needed reoperations for recurrent herniation. Significant but subjective reduction in fibrosis was observed in these patients.

Conclusion: The findings provide confidence that CMC/PEO gel is well tolerated as an agent to achieve reduction of fibrosis in lumbar disc surgery. Further formal prospective study is recommended in this area of unmet need.

背景:硬膜外纤维化被认为是背部手术失败综合征(FBSS)的病因之一,当粘连/纤维化瘢痕组织过多时,神经组织会与周围肌肉或骨骼拴在一起,从而导致压迫、疼痛或不适。因此,纤维化抑制剂可以提高脊柱手术的成功率,减少再次手术的需要。近年来,用于预防硬膜外周围纤维化和术后粘连的生物可吸收凝胶或薄膜相继问世,临床前景看好。其中包括一种由羧甲基纤维素(CMC)和聚氧化乙烯(PEO)组合而成的 100% 合成、无菌、可吸收凝胶,用于包裹硬脑膜以减少椎间盘切除术后的瘢痕,并于 2002 年在欧洲上市。然而,考虑到这一问题的严重性以及使用其他类型减少粘连剂的不利经验,我们科室决定在大量接受脊柱疝显微椎间盘切除术的患者中评估 CMC/PEO 的安全性:为了确定羧甲基纤维素/聚环氧乙烷(CMC/PEO)凝胶作为抗粘连凝胶的安全性并评估其疗效,由一名外科医生连续为 396 名接受腰椎间盘切除术的患者在手术结束后注射了 CMC/PEO 凝胶。根据标准临床实践对患者进行了随访,并审查了副作用记录,如皮肤反应、全身反应或局部积液。复发疝气的再手术包括纤维化减少的评估:结果:未发现与产品相关的并发症。结果:未观察到与产品相关的并发症,有五名患者因疝气复发需要再次手术。在这些患者中观察到纤维化明显但主观的减轻:结论:研究结果使我们确信,CMC/PEO凝胶作为腰椎间盘手术中减少纤维化的一种药物,具有良好的耐受性。建议在这一尚未满足需求的领域进一步开展正式的前瞻性研究。
