Background: Laparoscopic cholecystectomy (LC) is incapacitated by occurrence of bile duct injury (BDI). Precise identification of the frequently variable biliary anatomy is important for prevention of BDI. Rouviere’s sulcus received a significant interest as useful landmark to prevent BDI. This study aims to describe the frequency of Rouviere’s sulcus, its various patterns, dimension and to assess its usefulness as a landmark during LC. Methods: The study was carried on 100 consecutive cases of LC performed at our center between July 2017 and July 2018. Analysis of video recording of the laparoscopic procedure together with operative measurements was used to assess frequency, pattern, direction and various measurements of Rouviere’s sulcus. Results: Rouviere’s sulcus was evident during LC in 86% of cases and the sulcus type (whether open or closed) constituted 80.2% of evident Rouviere’s sulcus. The average measurement for this type was found to be about an inch in length, and less than 1 cm in both width and depth. Closed type of Rouviere’s sulcus was significantly narrower compared to open type (p = 0.00), while the difference in length and depth did not reach statistical significance. Conclusion: Rouviere’s sulcus is evident in majority of cases with sulcus type as its commonest pattern. Rouviere’s sulcus served as a useful landmark if it was visualized and not vertically directed. It allows for safe biliary dissection through identifying the level of common bile duct in more 86% of cases.
背景:腹腔镜胆囊切除术(LC)由于胆管损伤(BDI)的发生而无法进行。准确识别经常变化的胆道解剖结构对于预防BDI非常重要。Rouviere沟作为预防BDI的有用标志受到了极大的关注。本研究旨在描述Rouviere沟的频率,其各种模式,维度,并评估其作为LC中里程碑的有用性。方法:选取2017年7月至2018年7月在我中心连续行LC的100例患者为研究对象。分析腹腔镜手术录像及手术测量,评估Rouviere沟的频率、形态、方向及各种测量值。结果:LC术中鲁维埃沟明显率为86%,其中开闭型占明显鲁维埃沟的80.2%。这种类型的平均测量长度约为一英寸,宽度和深度均小于1厘米。闭合型Rouviere沟较开放型窄(p = 0.00),长度和深度差异无统计学意义。结论:鲁维埃沟在多数病例中表现明显,以沟型最常见。鲁维埃沟是一个有用的标志,如果它是可视化的,而不是垂直指向。在86%以上的病例中,它可以通过识别胆总管的水平进行安全的胆道剥离。

Background: Cecal volvulus is a rare cause of adult intestinal obstruction occurring 2.8– 7.1 persons per million per year. Its rarity and the variety of clinical symptoms may lead to a delay in the diagnosis and appropriate intervention. Case Presentation: Here, we present a 25-year old female patient from a rural area who presented with a 3-day history of colicky abdominal pain and vomiting of bilious intestinal content; she had also developed abdominal distension, failed to pass feces, and flatus. She underwent emergency laparotomy, where the intraoperative finding was a perforated 360 degrees counterclockwise volvulated cecum, and a right hemicolectomy was performed with primary ileotransverse anastomosis. Discussion: Cecal volvulus is the axial rotation of the cecum, ascending colon, and terminal ileum. This can result either in complete or partial obstruction of the affected segment of the intestine with impending vascular compromise and gangrene, which mandates a timely diagnosis and intervention. Conclusion: Cecal volvulus is a rare cause of adult intestinal obstruction, and urgent surgical intervention saves the life of patients. of surgery from to surgical procedures covered.

Purpose: Faster surgery has been associated with better outcomes. In the present study, we aimed to determine whether surgical duration affected overall survival (OS) in patients undergoing esophagectomy. Additionally, we assessed factors that influence surgical duration. Patients and Methods: This single-center retrospective cohort study included 128 patients who underwent Ivor-Lewis esophagectomy by a single surgeon between 2005 and 2019. The Cox proportional hazard model was used to evaluate the association of OS with the following variables: surgical duration, neo-adjuvant chemotherapy, pathological grade of depth of tumor invasion, lymph node (LN) metastasis, body mass index (BMI), and cervical LN dissection. Additionally, factors associated with prolonged surgical duration were examined by logistic regression analysis. Results: Based on the multivariate analysis, surgical duration was not associated with OS [hazard ratio (HR), 1.065; 95% confidence interval (CI), 0.586–1.937; P = 0.837]. On the other hand, tumor invasion (HR, 2.901; 95% CI, 1.483–5.674; P = 0.002) and LN metastasis (HR, 2.338 2.403; 95% CI, 1.237–4.420 1.257–4.593; P = 0.009 0.008) significantly influenced OS. The assessment of variables affecting surgical duration showed that BMI had a significant effect on surgical duration (odds ratio, 2.790; 95% CI, 1.254–6.204, P = 0.012). Conclusion: According to the analysis of patients who underwent the same surgical approach by a single surgeon, surgical duration of esophagectomy for esophageal cancer was significantly influenced by BMI; however, surgical duration had no impact on patient survival.
目的:更快的手术与更好的预后相关。在本研究中,我们旨在确定手术时间是否影响食管切除术患者的总生存期(OS)。此外,我们评估了影响手术时间的因素。患者和方法:这项单中心回顾性队列研究包括128名在2005年至2019年期间由一名外科医生进行Ivor-Lewis食管切除术的患者。采用Cox比例风险模型评估OS与以下变量的关系:手术时间、新辅助化疗、肿瘤浸润深度的病理分级、淋巴结(LN)转移、体重指数(BMI)和颈部LN清扫。此外,通过logistic回归分析检查与手术时间延长相关的因素。结果:基于多因素分析,手术时间与OS无相关性[危险比(HR), 1.065;95%置信区间(CI), 0.586-1.937;P = 0.837]。另一方面,肿瘤侵袭性(HR, 2.901;95% ci, 1.483-5.674;P = 0.002)和淋巴结转移(HR, 2.338 2.403;95% ci, 1.237-4.420, 1.257-4.593;P = 0.009 - 0.008)显著影响OS。影响手术时间的变量评估显示,BMI对手术时间有显著影响(优势比,2.790;95% ci, 1.254-6.204, p = 0.012)。结论:通过对同一手术入路患者的分析,BMI对食管癌食管切除术手术时间有显著影响;然而,手术时间对患者的生存没有影响。

Background: Head injury is one of the most common reasons for patient admission and death in surgical units of Ethiopian hospitals, but little is known about the problem in North-central Ethiopia. Therefore, this study aimed to assess the magnitude and associated factors of head injury at Debre Tabor Teaching and Referral Hospital in south Gondar zone, North-central Ethiopia. Methods: A cross-sectional study was conducted on 370 trauma patients at Debre Tabor Teaching and Referral Hospital from November 1 to December 30, 2019, using a systematic random sampling technique. The data were collected through a face-to-face interview. The data were analyzed using SPSS version 23. Bivariate and multivariable logistic regression analyses were performed to identify factors associated with head injury. P-value <0.05 was used to declare statistical significance. Results: The mean (±SD) age of patients was 41.4 (± 11.6) years. The prevalence of head injury was 39.7%, 95% CI (34.9–44.9%). Two hundred sixty-five (72%) were male and 259 (70%) of all trauma patients were from rural residents. The study also found that younger age (20–24 years) [AOR=1.2; 95% CI (1.29–8.86)], being male [(AOR=2.02; 95% CI (1.31– 6.24)], alcohol use [(AOR=6.31; 95% CI (2.03–16.08)], and rural residence [(AOR= 1.40; 95% CI (1.13–6.94)] were the factors associated with head injury. Conclusion: Like other studies done in Ethiopia, head injury is a major problem in the study area. The study also revealed that socio-demographic and behavioral factors are mainly associated with head injury. Therefore, appropriate prevention strategies should be devised and implemented against the contributing factors both at the individual and community level to minimize the risk of head injury.
背景:头部受伤是埃塞俄比亚医院外科病房患者入院和死亡的最常见原因之一,但对埃塞俄比亚中北部的这一问题知之甚少。因此,本研究旨在评估埃塞俄比亚中北部贡达尔区南部Debre Tabor教学和转诊医院头部损伤的程度和相关因素。方法:采用系统随机抽样技术,对2019年11月1日至12月30日在Debre Tabor教学和转诊医院的370名创伤患者进行横断面研究。这些数据是通过面对面的访谈收集的。使用SPSS 23版对数据进行分析。进行双变量和多变量逻辑回归分析,以确定与头部损伤相关的因素。P值<0.05用于说明统计学意义。结果:患者的平均(±SD)年龄为41.4(±11.6)岁。头部损伤的发生率为39.7%,95%可信区间(34.9-44.9%)。265名(72%)为男性,259名(70%)创伤患者来自农村居民。该研究还发现,年龄较小(20-24岁)[AOR=1.2;95%置信区间(1.29-8.86)]、男性[(AOR=2.02;95%可信区间(1.31-6.24)]、饮酒[(AOR=6.31;95%置信度(2.03-16.08)]和农村居住[(AOD=1.40;95%CI(1.13-6.94)]是与头部损伤相关的因素。结论:与埃塞俄比亚的其他研究一样,头部损伤是该研究领域的一个主要问题。研究还表明,社会人口和行为因素主要与头部损伤有关。因此,应针对个人和社区层面的影响因素制定和实施适当的预防策略,以最大限度地降低头部受伤的风险。

Background: Pilonidal sinus (PNS) is a common disorder that mainly affects young adults. It can be asymptomatic or presented by discomfort, inflammation, abscess or sinus formation. Despite current advances in surgical techniques, the best option to treat PNS is not yet well defined. Many studies reported techniques that involved excision of the sinus and closure of the deep and superficial layers but leaving the skin open. Aim: We aim to compare between the excision and primary midline closure with suction drain versus the partial closure technique as treatment options for PNS in terms of recovery, wound complications and recurrence rate. Patients and Methods: A prospective comparative study at Ain Shams University Hospitals that included 80 patients with PNS was conducted from January 2018 to June 2019. They were divided randomly into group A; 40 patients that had the midline closed method with suction drain and group B; 40 patients that underwent the partial closure technique. Both groups were followed up for 1 year, detecting healing time, wound complications, return to usual activities and recurrence rate. Results: We detected significant differences between both groups as regards to pain and discomfort postoperatively, favoring the partial closure group. Mean time to wound healing was significantly shorter among group A (14.43 ± 3.13) though mean time of return to usual activities was faster among the partial closure group (14.45 ± 1.15). There were no statistically significant differences between both groups as regards to wound infection, dehiscence or hematoma formation. Wound seroma was more among group A. Conclusion: The partial midline closure technique showed comparable results to the closed method with suction drain in management of PNS disease. Indeed, it shows less postoperative complications and a faster return to usual daily activity. Yet, more studies are required to demonstrate its reproducibility.
背景:毛突窦(PNS)是一种常见病,主要影响年轻人。它可以是无症状或表现为不适,炎症,脓肿或窦形成。尽管目前外科技术进步,但治疗PNS的最佳选择尚未明确。许多研究报告的技术包括切除鼻窦和关闭深层和浅层,但保留皮肤开放。目的:我们的目的是比较在恢复、伤口并发症和复发率方面,作为PNS的治疗选择,切除和一次中线闭合与抽吸引流与部分闭合技术。患者和方法:2018年1月至2019年6月,在艾因沙姆斯大学医院进行了一项前瞻性比较研究,纳入了80例PNS患者。随机分为A组;B组和中线封闭吸液引流40例;40名患者接受了部分缝合术。两组均随访1年,观察愈合时间、创面并发症、恢复正常活动及复发率。结果:我们发现两组在术后疼痛和不适方面有显著差异,偏向部分闭合组。A组平均创面愈合时间(14.43±3.13)明显缩短,部分闭合组平均恢复正常活动时间(14.45±1.15)明显缩短。两组在伤口感染、裂开、血肿形成方面无统计学差异。结论:部分中线闭合术治疗PNS疾病的效果与闭合加吸引引流术相当。事实上,它显示出更少的术后并发症和更快地恢复正常的日常活动。然而,需要更多的研究来证明其可重复性。

: Cord congenital hernia is a condition in which due to a patent umbilical ring, intestinal components protrude into the umbilical cord. Although post-natal umbilical hernia is not uncommon, its congenital form is an uncommon phenomenon (incidence rate about 0.2%) with an excellent post-surgical prognosis. It is frequently misdiagnosed as a small omphalocele. Additionally, if it is undiagnosed at the time of birth, clamping the umbilical cord can cause iatrogenic atresia of the ileum. Hence, during a physical exam, it is mandatory to look carefully for any skin folds in the form of a collar or defects in the umbilical ring or abdominal wall to avoid misdiagnosis. We report a full-term male newborn present with umbilical cord hernia, who underwent successful open surgery, with extra focus on the management and outcome of this disease. return to the abdominal cavity, the umbilical cord hernia would occur. Compared to post-natal umbilical hernia, Its congenital form is less common, with an incidence rate of 1 in 5000 newborns. We report a full-term male newborn product cesarean section with hernia of the umbilical cord, which was successfully treated with open surgery. The post-operation recovery period was uneventful, and the patient was discharged to home within three days and is currently under follow-up.
:脐带先天性疝是一种由于脐带环未闭合,肠道成分突出到脐带中的情况。尽管产后脐疝并不罕见,但其先天性形式是一种罕见现象(发病率约为0.2%),术后预后良好。它经常被误诊为小脐膨出。此外,如果在出生时未被诊断,夹脐带可能会导致医源性回肠闭锁。因此,在体检过程中,必须仔细检查衣领形式的皮肤褶皱或脐环或腹壁的缺陷,以避免误诊。我们报告了一名患有脐疝的足月男性新生儿,他接受了成功的开放手术,并特别关注这种疾病的管理和结果。回到腹腔,就会发生脐疝。与产后脐疝相比,其先天性形式不太常见,新生儿发病率为1/5000。我们报告了一例足月男性新生儿剖宫产并发脐疝,并成功地通过开放手术进行了治疗。术后恢复期很平静,患者在三天内出院回家,目前正在随访中。

Background: Laryngeal mask airway (LMA) is a useful airway device which provides an alternative to ventilation through a face mask or endotracheal tube during ophthalmic surgery. It can be removed either when a child awakens or deeply anesthetized. But there is little evidence for best practice on the timing of their removal after ophthalmic surgery in the pediatric population. It has been studied by various investigators but with conflicting results and conclusions. Objective: The aim of this study was to evaluate the effect of depth of anesthesia (awake or deep anesthesia) on the incidence of airway associated complications during LMA removal. Methodology: A prospective observational cohort study was conducted from January to April 2018. Sixty-two American Society of Anesthesiologists physical status I and II pediatric (aged 2–8 years) patients who underwent ophthalmic procedures under general anesthesia with LMA were recruited. Grouping (awake group or deep group) was done based on independent decision of on duty anesthetist and halothane 1–1.5% was used as maintenance anesthesia. The incidence of airway-related adverse events like coughing, upper airway obstruction (Laryngospasm), breath holding, desaturation, excessive salivation, biting, vomiting, and retching with LMA removal were evaluated. Collected data were entered into Epi Info™ version 7.0 and transported to the SPSS version 22 for analysis. Fisher’s exact test and Chi-square test were used to analyze dependent variables and P-values less than 0.05 were considered statistical significance. Results: There were no significant differences in airway-related adverse events. The incidence of coughing (12.9%, 6.5%), upper airway obstruction (41.9%, 35.5%), breath holding (9.7%, 3.2%), desaturation (16.1%, 22.6%), excessive salivation (19.4%, 12.9%), and biting (6.5%, 0%) between awake and deep groups respectively with (p > 0.05). Laryngospasm, vomiting, and retching did not occur in either group. Conclusion: There was no significant difference in the incidence of airway-related adverse events whether the LMA was removed in a deep or awake condition.
背景:喉罩气道(LMA)是一种有用的气道设备,它在眼科手术中提供了通过面罩或气管插管进行通气的替代方案。它可以在孩子醒来或深度麻醉时取出。但是,在儿科人群中,几乎没有证据表明眼科手术后摘除它们的最佳时机。不同的研究者对它进行了研究,但结果和结论并不一致。目的:本研究的目的是评估深度麻醉(清醒或深度麻醉)对LMA摘除过程中气道相关并发症发生率的影响。方法:2018年1月至4月进行了一项前瞻性观察性队列研究。招募了62名美国麻醉师协会身体状况I和II的儿科(年龄2-8岁)患者,他们在LMA全身麻醉下接受了眼科手术。分组(清醒组或深组)根据值班麻醉师的独立决定进行,使用1-1.5%的氟烷作为维持麻醉。评估了移除LMA后与气道相关的不良事件的发生率,如咳嗽、上呼吸道阻塞(喉痉挛)、屏气、去饱和、唾液过多、叮咬、呕吐和干呕。收集的数据已输入Epi信息™ 7.0版本,并传输到SPSS版本22进行分析。Fisher精确检验和卡方检验用于分析因变量,P值小于0.05被认为具有统计学意义。结果:气道相关不良事件发生率无显著差异。清醒组和深部组咳嗽(12.9%,6.5%)、上呼吸道阻塞(41.9%,35.5%)、屏气(9.7%,3.2%)、去饱和(16.1%,22.6%)、流涎过多(19.4%,12.9%)和叮咬(6.5%,0%)的发生率分别为(p>0.05)。两组均未出现喉痉挛、呕吐和干呕。结论:无论是在深部还是清醒状态下移除LMA,气道相关不良事件的发生率都没有显著差异。

Introduction: Clinical record-keeping is a crucial part of professional practice and the delivery of quality healthcare. Poor intraoperative recording contributes to poor patient safety and unavailability of data in cases of medico-legal review or research purpose. Additionally, such records may provide an invaluable guide to subsequent practitioners involved with the patients’ management. Method and Materials: A descriptive study was conducted at Dilla University Referral Hospital from October 1 to November 30, 2020. Fifty-one intraoperative record indicators were developed and those requiring a definition for completeness were predefined. The expected completion rate was 100% for all indicators. Indicators with >90% completion rate were marked as acceptable and completion rate of <50% was considered as areas of the critical need for improvement. SPSS version 20 was used for data analysis. Results: A total of 164 intraoperative anesthesia record tools were reviewed, and none of the indicators had a completion rate of 100%. The intraoperative anesthesia record tools completion rate was >90% for documentation of sex, procedure starting time, name of the procedure, dose/volume and route of a specific drug given, standards of monitoring used, intraoperative blood pressure, and pulse rate record with time. Patient identity, name of professionals, baseline oxygen saturation, unit of measures of baseline vital signs, patient’s status on transfer, the total amount of each drug administered, intraoperative electrocardiographic rhythm, total amount of blood loss, total amount of urine output, and postoperative management plan were among indicators found below average (<50%) completion rate. Conclusion and Recommendation: Most of the indicators for manual intraoperative anesthesia recording were found incomplete and below the standards. Different strategies like regular feedback and monitoring to improve the practice have to be instituted. Introducing an electronic recording system may also help to overcome the problem.
引言:临床记录保存是专业实践和提供优质医疗保健的重要组成部分。术中记录不佳会导致患者安全性差,以及在医疗法律审查或研究目的的情况下无法获得数据。此外,这些记录可以为参与患者管理的后续从业者提供宝贵的指导。方法和材料:一项描述性研究于2020年10月1日至11月30日在迪拉大学转诊医院进行。制定了51个术中记录指标,并预定义了需要完整性定义的指标。所有指标的预期完成率为100%。完成率>90%的指标被标记为可接受,完成率为90%,用于记录性别、手术开始时间、手术名称、给药的剂量/体积和途径、使用的监测标准、术中血压和随时间变化的脉搏率记录。患者身份、专业人员姓名、基线血氧饱和度、基线生命体征测量单位、患者转移状态、每种药物的给药总量、术中心电图节律、总失血量、总尿量和术后管理计划是低于平均(<50%)完成率的指标。结论和建议:术中手动麻醉记录的大部分指标不完整且低于标准。必须制定不同的策略,如定期反馈和监督,以改进实践。引入电子记录系统也可以帮助克服该问题。
