Project description:BackgroundDifferent video-assisted thoracoscopic surgery (VATS) approaches may related to heterogeneous clinical outcomes in anterior mediastinal tumor surgery. Herein, we assessed the comparison between the subxiphoid and intercostal approach, and also compare the left versus the right incision in the intercostal approach for anterior mediastinal tumor patients.MethodsClinical data of patients receiving thoracoscopic anterior mediastinal tumor resection were retrospectively collected. Patients were divided into two groups according to the approaches: subxiphoid and the intercostal group. The intercostal group was further subdivided into two groups according to different sides: left and right incision group. Intraoperative and postoperative variables were compared between subgroups.ResultsA total of 238 patients were consecutively included in this analysis; 198 (83.2%) patients received intercostal procedure and 40 (16.8%) patients received subxiphoid approach. After 1:1 propensity score matching, all baseline characters were well balanced between intercostal and subxiphoid approach, left and right intercostal approach. The visual analogue scale (VAS) pain score was lower in patients underwent subxiphoid approach than intercostal group at first post-operative evaluation in 12-24 h (4.36 vs. 2.23; P=0.03). According to left and right approach, postoperative drainage time (1.9 vs. 1.2 days, P=0.016), postoperative drainage volume (312.1 vs. 193.9 mL, P=0.041) and hospitalization time (5.3 vs. 4.1 days, P=0.043) were significantly increased in the left thoracic approach group compared with the right thoracic approach.ConclusionsSubxiphoid approach is associated with less pain compared with intercostal approach. The right intercostal thoracic approach may offer better clinical effect of short-term postoperative recovery.

Project description:Background When placenta accreta complicates a delivery, the typical management is to perform a cesarean hysterectomy. Other management strategies, including leaving the placenta in situ, have been attempted and supported in some cases. This may allow for an interval hysterectomy, which can potentially decrease average blood loss and/or allow a minimally invasive approach to the hysterectomy. Cases We present two cases of women with invasive placentation managed conservatively with interval hysterectomy. One woman was managed with robotic-assisted laparoscopic surgery and the other with an open surgical approach. Conclusion These cases highlight the successful use of conservative management for invasive placentation in two stable patients and showcase the novel use of a robotic-assisted laparoscopic surgery for management of invasive placentation.

Project description:BackgroundA rising number of patients are surgically treated for heart failure at the more advanced stage, thanks to the increasing use of left ventricular assist device (LVAD) as a reliable alternative to heart transplantation (HTx). However, it is still unknown whether differences exist between the two surgical approaches in the efficacy of rehabilitation programmes. Therefore, aim of this study was to evaluate whether functional capacity and rehabilitative outcomes differ between HTx and implantation of LVAD.Methods and resultsWe enrolled 51 patients with HTx and 46 with LVAD upon admission to our rehabilitation-unit. We evaluated six-minute walking test (6MWT), resting oxygen saturation (SaO2) and nutritional assessment before and after a standardised cardiovascular rehabilitation programme. HTx and LVAD groups differed in age, anthropometric variables, gender distribution. Upon enrolment, 6MWT distance was similar in the two groups, whereas malnutrition was less frequent and the waist circumference/height ratio (WHtR) was greater in LVAD patients. SaO2 was greater in HTx patients. Rehabilitation improved SaO2, 6MWT distance and nutritional status. The difference in malnutrition disappeared, but WHtR remained higher in the LVAD and SaO2 higher in the HTx patients; the 6MWT distance improved more in the HTx patients. Multivariate linear regression analysis confirmed that the type of intervention was independent predictor of 6MWT distance after rehabilitation.ConclusionsHTx patients improve more rapidly and perform better after rehabilitation, suggesting the need for more tailored rehabilitation training for LVAD patients.

Project description:BackgroundThere is an increasing global interest in selection processes for candidates to surgical training. The aim of the present study is to compare selection processes to specialist surgeon training in the European Union (EU). A secondary goal is to provide guidance for evidence-based methods by a proposed minimum standard that would align countries within the EU.MethodsPublications and grey literature describing selection strategies were sought. Correspondence with Union Européenne des Médecins Specialists (UEMS) Section of Surgery delegates was undertaken to solicit current information on national selection processes. Content analysis of 13 semi-structured interviews with experienced Swedish surgeons on the selection process. Two field trips to Ireland, a country with a centralized selection process were conducted. Based on collated information typical cases of selection in a centralized and decentralized setting, Ireland and Sweden, are described and compared.ResultsA multitude of methods for selection to surgical training programs were documented in the 27 investigated countries, ranging from locally run processes with unstructured interviews to national systems for selection of trainees with elaborate structured interviews, and non-technical and technical skills assessments. Associated with the difference between centralized and decentralized selection systems is whether surgical training is primarily governed by an employment or educational logic. Ireland had the most centralized and elaborate system, conducting a double selection process using evidence-based methods along an educational logic. On the opposite end of the scale Sweden has a decentralized, local selection process with a paucity of evidence-based methods, no national guidelines and operates along an employment logic, and Spain that rely solely on examination tests to rank candidates.ConclusionThe studied European countries all have different processes for selection of surgical trainees and the use of evidence-based methods for selection is variable despite similar educational systems. Selection in decentralized systems is currently often conducted non-transparent and subjectively. A suggested improvement towards an evidence-based framework for selection applicable in centralized and decentralized systems as well as educational and employer logics is suggested.

Project description:Objective: The purpose of this study was to assess understanding of the hysterectomy procedure and uterine fibroids among women in a general gynecology clinic. Materials and Methods: This was an anonymous cross-sectional survey. We adapted and pilot tested a survey instrument designed to assess understanding of the hysterectomy procedure and of uterine fibroids. The final version of the survey consisted of basic demographic questions, followed by 28 knowledge questions (Canadian Task Force Classification II-2). The survey was disseminated to women in the waiting room of one of our gynecology clinics. The patient population included women 18 years and older. Results: The mean age of respondents was 33.5 years old. In total, 69.5% of the respondents had at least some college education. In the group of questions related to different types of hysterectomies, the most poorly answered question was "Which type of hysterectomy has the highest risk of damage to the bladder?" Less than 40% of the respondents were able to identify a laparoscopic and robotic hysterectomy based on a written description. Of questions about uterine fibroids, the most poorly answered question was whether cancer that looks like fibroids is common, with >90% of the respondents incorrectly thinking that cancer that resembled fibroids is common. More than half of respondents did not know what a fibroid is. Conclusions: In this analysis of the understanding of the hysterectomy procedure and fibroids among an educated population, overall understanding was poor. Specific areas where knowledge was particularly poor were the different ways of doing a hysterectomy and uterine fibroids.

Project description:IntroductionBrachial plexus injury (BPI) can result in complete loss of neurological function and reduces the quality of life. Nerve transfer, nerve grafting, external neurolysis, and free functional muscle transfer are several management options that determine the eventual outcomes. Despite various methods of treatment, hardly any literature compares directly the result of these treatment options. This study aimed to analyze differences in clinical and functional outcomes after a reconstructive surgery.MethodsA cohort retrospective study was conducted on traumatic brachial plexus injured patients aged from 17 to 65 years at one hospital in Surabaya, Indonesia, from January 2009 to December 2019. All patients were divided into 4 groups depending on the types of surgery. The clinical outcomes were measured using elbow and shoulder muscle strength, elbow and shoulder range of motion (ROM), and pain level (measured using Visual Analog Scale/VAS); the functional outcomes were measured using the overall quality of life using the DASH (disabilities of the arms, shoulder, and hand) score.ResultsThis study included 316 patients comprising of 256 males with an average age of 27.53 ± 11.37, an average time from injury to surgery of 17.74 ± 35.82 months, and average follow-up duration of 59.89 ± 37.68 months. Most cases were caused by road traffic accidents (77.22%) and most were total arm type of BPI injury (70.7%). There was no significant difference in the mean values of study parameters except in VAS (p = 0.042) as nerve grafting resulted in less pain than external neurolysis (2.27 ± 1.03 vs. 3.68 ± 1.93, respectively; p = 0.017). Besides, nerve transfer procedure also resulted in less pain compared to external neurolysis (2.99 ± 1.84 vs. 3.68 ± 1.93, respectively; p = 0.036).ConclusionWe found no significant difference between types of surgery and the postsurgical outcome. A wider multicenter study was required to define the clinical and functional outcomes clearly.

Project description:Fracture of the zygomaticomaxillary complex (ZMC) is one of the most common facial injuries. A previous study has performed 3D analyses of the parallel and rotational displacements that occur in a fractured ZMC. However, few studies have investigated adequate fixation methods according to these displacements. Here, we assessed whether specific approaches and fixation methods for displacement of ZMC fractures produce esthetic results.Hospital records and pre- and post-surgical computed tomographic scans of patients treated for ZMC fractures at the Department of Oral and Maxillofacial Surgery, College of Dentistry, Wonkwang University, between January 2010 and December 2015, were selected. Data were analyzed according to the direction of displacement and post-reduction prognosis using a 3D software.With ZMC fractures, displacement in the posterior direction occurred most frequently, while displacement in the superior-inferior direction was rare. A reduction using a transconjunctival approach and an intraoral approach was statistically better than that using an intraoral approach, Gillies approach, and lateral canthotomy approach for a posterior displacement (P?<?0.05).When posterior displacement of a fractured ZMC occurs, use of an intraoral approach and transconjunctival approach simultaneously is recommended for reducing and fixing the displaced fragment accurately.

Project description:PurposeElectronic retinal implants restore some visual perception in patients blind from retinitis pigmentosa. Eye movements cause mechanical stress in intraorbital power supply cables leading to cable breaks. By using computer tomography (CT) scans at the extreme positions of the four cardinal gaze directions, this study determined in vivo, which of three surgical routing techniques results in minimal bending radius variation and favors durability.MethodsNine patients received the first-generation subretinal implant Alpha IMS (Retina Implant AG, Reutlingen, Germany) in one eye. Three techniques for intraorbital cable routing were used (straight cable route (A), parabulbar loop (B), and encircling band (C)), each in three patients. All patients underwent computer tomography of the orbital region. The bending radius of the intraorbital cable was measured with the DICOM viewer Osirix v4.1.2 (Pixmeo SARL, Bernex, Switzerland) and served as indicator for mechanical stress.ResultsAverage bending radius variation was 87% for method A, 11% for method B, and 16% for method C. Methods A and B (P = 0.005) and methods A and C (P = 0.007) differed significantly, while method B and C showed no statistical difference (P = 0.07).ConclusionsCompared to straight routes, arcuated cable routes significantly reduce cable movement and bending. Due to an easier surgical procedure, a parabulbar loop is the preferred method to minimize bending radius variation and prolong survival time of electronic subretinal implants.Translational relevanceCT analysis of cable bending of implanted medical devices allows to determine which surgical routing technique favors durability in vivo.
