Background
The completeness of the resected mesorectum is a quality metric in rectal cancer surgery and has been related to oncological outcomes. Our aim was to identify variables associated with non-complete mesorectal excision and determine any effect on overall survival.Methods
Consecutive patients who underwent curative intent surgery for rectal adenocarcinoma (2009–2016) were identified from a prospectively-maintained institutional database. Patients were grouped according to their mesorectal grade: complete, near-complete and incomplete. Multivariate analysis was performed to identify the association between various patient, disease and surgeon-related characteristics and mesorectal grading. Log-rank tests were used to evaluate any difference in overall survival between the groups.Results
689 patients met inclusion criteria. Demographics and perioperative variables were comparable between the groups. On multivariate analysis, abdominoperineal resection, and involved circumferential resection margin were significantly associated with non-complete mesorectum. Finally, patients with non-complete mesorectal grading have approximately twice the hazard of death compared to those with complete mesorectal grading.Conclusions
Several factors are associated with a non-complete mesorectal excision. Non-complete mesorectal grade is associated with decreased survival. 相似文献2.

Background
Incomplete and flawed national databases reveal strikingly inferior outcomes for rectal cancer patients resected at “low” versus “high “ volume hospitals, therefore, a study of outcomes of a “high” volume surgeon in a “low” volume Midwest community hospital setting examined this perception in comparison to contemporary studies.Methods
Review of 109 consecutive patients who underwent open resection of rectal cancer following neoadjuvant therapy, 1999–2010.Results
Despite the majority of tumors in the low rectum (54%), the rate of abdominoperineal resection was only 39% with R0 resection achieved in 94% and primary anastomosis in 61/109 patients (56%). Disease-free survival (DFS) 73%: stage 0 (complete response)- 100%, stage I- 88%, stage II- 68%, stage III- 50%, stage IV- 0% with recurrence rate of 11% (local recurrence (LR) - 3%, distant - 8%).Conclusion
Outcomes of rectal cancer resection by a “high” volume surgeon in a “low” volume Midwest community hospital setting were comparable to contemporary studies from tertiary care institutions. Geographic location and hospital capacity matter less than access to multispecialty expertise providing neoadjuvant therapy and following standard principles of oncologic resection, in efforts to optimize rectal cancer outcomes. 相似文献3.

Case series.Introduction
Upper extremity (UE) trauma and subsequent immobilization affects functional performance.Purpose of the Study
Determine the usefulness and feasibility of unilateral hand training (UHT) on improving functional performance in patients with UE trauma.Methods
Nine participants received UHT within 10 days of immobilization. Functional performance, dexterity, grip, and pinch strength were measured at initial and 4-week visits. Qualitative interviews were coded to develop themes.Results
All Jebsen-Taylor hand function test subtests improved from pretest to post-test. Disabilities of the Arm, Shoulder and Hand scores of all 9 participants improved. Functional performance was more impaired for participants with dominant UE injury. Four themes emerged: participants were forced to alter or avoid most daily activities, had an increased dependency on others, took longer to perform activities, and felt UHT decreased the impact of UE trauma on function.Discussion
Functional performance was impaired for all participants. Participants believed that UHT was useful and contributed to improved function.Conclusion
This case series tracked a comprehensive intervention based on a holistic activities of daily living framework that considered the nuances of individual complexities of immobilization following hand trauma. Knowledge from this study supports an early intervention like UHT to educate clients on effective strategies to improve immediate activities of daily living functioning and potentially prevent longer term impairments. 相似文献4.

Background
Although the creation of a stoma reduces the risk of septic pouch complications following ileal pouch-anal anastomosis (IPAA), the stoma itself and its reversal can give rise to substantial morbidity during the two- or three-stage concept. Aim of study is to compare stoma-related complications in Ulcerative Colitis patients undergoing laparoscopic versus open IPAA.Methods
We collected data on 250 IPAA patients from two Italian Centres between 2005 and 2015. We compared perioperative and postoperative events in 150 open vs 100 laparoscopic IPAA. We performed a case-matched analysis based on baseline differences among groups to compare the rate of mechanical complications.Results
There were no significant differences between open and laparoscopic IPAA in overall stoma complications (complications during ileostomy: 11.3% vs 12%,p?=?0.8; early complications: 10% vs 8%,p?=?0.5; late complications: 12.6% vs 6%,p?=?0.08). The case-matched analysis found a slightly reduced incidence of obstructive complications at any stage with laparoscopy.Conclusions
Overall stoma related complications do not seem to be reduced by minimally-invasive approach itself, but patients might experience less mechanical problems with laparoscopy without conversion. 相似文献5.

Background
Microvascular invasion (MVI) has recently been reported to be an independent prognostic factor in patients with hepatocellular carcinoma (HCC). This study compared the outcomes of adjuvant transarterial chemoembolization (A-TACE) after hepatic resection (HR) in patients with HCC involving MVI.Methods
This prospective study involved 200 consecutive patients with MVI-HCC who underwent HR alone (n?=?109) or HR with A-TACE (n?=?91).The Kaplan-Meier method was used to compare disease-free survival (DFS) and overall survival (OS).Results
The two groups showed similar DFS at 1, 2, and 3 years (P?=?0.077). The A-TACE group showed significantly higher OS than the HR-only group (P?=?0.030). Subgroup analysis showed that A-TACE was associated with significantly higher DFS and OS among patients with a tumor diameter >5?cm or with multinodular tumors.Conclusions
A-TACE may improve postoperative outcomes for MVI-HCC patients, especially those with tumor diameter >5?cm or multinodular tumors. 相似文献6.

Case series.Introduction
A salvaged limb is one that has undergone a major traumatic injury, followed by repeated surgical attempts in order to avoid amputation. Psychological recovery for individuals with lower extremity limb salvage has been examined in a number of studies. However, psychosocial reactions for individuals with upper extremity (UE) limb salvage are understudied in the literature.Purpose of the Study
The purpose of this study was to explore the process of psychosocial adaptation for 3 trauma cases after UE limb salvage.Methods
The Reactions to Impairment and Disability Inventory was used to assess psychosocial adaptation. Physical function outcomes (pain, range of motion, edema, sensation, and dexterity) are presented. The Disabilities of the Arm, Shoulder, and Hand measure was used to assess perceived disability. Medical and rehabilitation history are discussed for each case, in order to provide in-depth understanding of the impact of these injuries.Results
Reactions to injury varied across the cases; however, outcomes suggest that psychosocial adaptation may be influenced by the experience of pain, the ability to participate in valued roles and activities, and having a supportive social network.Discussion
For this population, therapists may consider emphasizing pain management, focusing on client-centered goals and interventions, and facilitating peer support. Providers should closely monitor patients for signs of poor adaptation, such as hand-hiding behaviors.Conclusions
This study is among the first to examine psychological outcomes for the UE limb salvage population. Future research would be beneficial to provide deeper understanding of the psychosocial challenges for these individuals. 相似文献7.

Background
This study aimed to identify differences in pattern recognition skill among individuals with varying surgical experience.Methods
Participants reviewed laparoscopic cholecystectomy videos of various difficulty, and paused them when the cystic duct or artery was identified to outline each structure on the monitor. Time taken to identify each structure, accuracy and work load, which was assessed using the NASA-Task Load Index (TLX), were compared among the three groups.Results
Ten students, ten residents and eight attendings participated in the study. Attendings identified the cystic duct and artery significantly faster and more accurately than students, and identified the cystic artery faster than residents. The NASA-TLX score of attendings was significantly lower than that of students and residents.Conclusions
Attendings identified anatomical structures faster, more accurately, and with less effort than students or residents. This platform may be valuable for the assessment and teaching of pattern recognition skill to novice surgeons.Short summary
Accurate anatomical recognition is paramount to proceeding safely in surgery. The assessment platform used in this study differentiated recognition skill among individuals with varing surgical experience. 相似文献9.

Introduction
The aim of this study was to determine whether complications following mastectomy with immediate breast reconstruction (IBR) were associated with breast cancer recurrence.Methods
A retrospective review was performed of women diagnosed with stage I-III breast cancer who underwent mastectomy with IBR between 2005 and 2010. Patient demographics, tumor data, surgical wound complications, treatment details and timing were recorded and analyzed.Results
We identified 458 women with a median follow up time of 7.6 years. A total of 22% of patients experienced IBR complications. There was a delay in initiation of adjuvant therapy in patients who had a complication (52 vs 41 days, p?<?0.001). There was no significant difference in recurrences between groups with and without complications (p?=?0.65).Conclusions
In breast cancer patients who undergo mastectomy with IBR, wound complications delayed initiation of adjuvant systemic therapy, but were not associated with an increased risk of cancer recurrence. 相似文献10.

Basic research (biomechanics).Introduction
The high degree of motion that occurs at the thumb metacarpophalangeal (MCP) joint must be taken into account when immobilizing a partially torn or repaired thumb ulnar collateral ligament.Purpose of the Study
To determine the efficacy of a radial-based thumb MCP-stabilizing orthosis in resisting abduction across the thumb ulnar collateral ligament.Methods
Ten fresh cadaveric hands were mounted to a custom board. An anteroposterior radiograph of the thumb was obtained with a 2 N preload valgus force applied to the thumb, and the angle between the Kirschner wires was measured as a baseline. Subsequently, 20, 40, 60, 80, and 100 N valgus forces were applied 15 mm distal to the MCP joint. Anteroposterior radiographs of the thumb were obtained after each force was applied. The angle of displacement between the wires was measured and compared with the baseline angle. The angles were measured with an imaging processing tool. A custom radial-based thumb MCP-stabilizing orthosis was fashioned for each cadaveric thumb by a certified hand therapist. The aforementioned loading protocol was then repeated.Results
The radial-based thumb MCP-stabilizing orthosis significantly reduced mean abduction angles at each applied load.Discussion
We found that our orthosis, despite being hand-based and leaving the thumb IP and CMC joints free, significantly reduced mean abduction angles at each applied load.Conclusions
This investigation provides objective evidence that our radial-based thumb MCP-stabilizing orthosis effectively reduces the degree of abduction that occurs at the thumb MCP joint up to at least 100 N.Level of Evidence

Introduction
"See one, do one, teach one" has represented the model for surgical education for over a century, however recent changes in education have reduced autonomy in training. The goal of this study was to assess the impact of autonomy on learning a procedural skill.Methods
Senior medical students were randomized and trained to performance a vascular anastomosis utilizing progressive autonomy vs. constant supervision. Performance was tested using videotaped technical grading and anastomotic pressure testing.Results
Mean baseline performance times and technical ratings were similar in both groups. Final completion times was faster in the autonomy group, 14:03min vs. 19:09min (p?=?0.02). Final technical ratings were similar, 40.0 vs. 39.2points (max?=?50), for each group and both demonstrated similar improvement in leak test against a standardized sample.Conclusion
Teaching a procedure, as a final step in graded autonomy, results in superior performance in timing while maintaining equal technical performance compared to trainees with less autonomy. 相似文献12.

Background
Immediately fatal motorcycle crashes have not been well characterized. This study catalogues injuries sustained in fatal motorcycle crashes and assesses the impact of crash conditions on injury patterns.Methods
Autopsy records from the office of the medical examiner of Kent County, MI and publicly available traffic reports were queried for information pertaining to motorcyclists declared dead on-scene between January 1, 2007, and December 31, 2016.Results
A total of 71 autopsies of on-scene motorcycle crash fatalities were identified. The two most prevalent injuries were traumatic brain injury (TBI) (85%) and rib fractures (79%). The majority of fatalities occurred in daylight hours (54.3%) and in a 55 mph speed limit zone (63.8%).Conclusions
This study provides a catalogue of the injuries sustained in immediately fatal motorcycle crashes and the associated conditions. Advocacy efforts that highlight the risks associated with motorcycle riding and that promote safe riding practices are warranted. 相似文献13.

Purpose
Predicting surgical risk is challenging. There is no curriculum to teach risk assessment to students. We hypothesize that a risk assessment curriculum will improve medical students’ confidence in and familiarity with assessing risk, and help identify barriers to assessing risk.Methods
Third year surgery clerkship students participated in a risk-assessment workshop. Students completed pre- and post-intervention surveys assessing their familiarity with models, and confidence in predicting postoperative complications. Additionally, they completed a retention survey 12-weeks following the session.Results
Following the session, confidence in predicting post-operative morbidity and mortality improved from <1% to 21.9% and 19.05% respectively. The majority of students continued to feel more confident mortality 12-weeks following the session. Not seeing attendings/residents use the calculator was a significant barrier to use.Conclusions
This novel risk assessment curriculum improved student confidence towards assessing risk up to three months following the session. Additionally, this study highlights that barriers exist to using risk assessment tools clinically. 相似文献14.

Background
Pre-internship boot camps have become popular platforms to rapidly teach skills to surgical interns. This study aimed to analyze psychomotor skill retention four months after completing a boot camp program.Methods
Surgical interns (n?=?20) took a baseline pre-test and then trained to proficiency (based on time and errors) for 5 knot tying, 4 simple suturing, and 2 running suturing tasks during a three-day boot camp. Three months later, all interns took a retention test.Results
Proficiency scores significantly improved on all task types from pre-test to post test and significantly regressed on all task types from post-test to retention test. Normalized scores decreased as the tasks became more complex (knot tying?=?93.5, simple suturing?=?89.1, running suturing?=?85.2, p?=?0.05).Conclusions
Boot camp style training can rapidly teach fundamental surgical skills to novices; however, skills regress significantly over time with a greater degree of regression seen on more complex skills. 相似文献15.

Clinical measurement.Introduction
Common provocative maneuvers to differentiate thumb carpometacarpal (CMC) osteoarthritis from other sources of pain are the grind, metacarpal (MC) flexion, and MC extension tests. A maneuver known as the pressure-shear test is described here.Purpose of the study
To compare the diagnostic value of the grind, metacarpal flexion, metacarpal extension, and pressure-shear tests for CMC osteoarthritis of the thumb.Methods
The diagnostic accuracy of each test was compared in 127 thumbs from 104 patients. Sensitivity, specificity, and predictive values of each test were calculated. In a secondary analysis, polychoric correlation coefficients were used to assess the correlation of each test with severity defined by Eaton-Littler stage.Results
The overall diagnostic accuracy of the thumb MC grind, pressure-shear, flexion, and extension tests were 70%, 98%, 47%, and 55%, respectively. The sensitivities were 64%, 99%, 36%, and 46%, respectively, and specificities were 100%, 95%, 100%, and 100%, respectively. For the diagnosis of Thumb CMC arthritis, the MC pressure-shear test was superior overall in terms of overall diagnostic accuracy and sensitivity, while having comparable specificity to the other maneuvers.Conclusion
The pressure-shear test was found to be superior to the commonly used grind maneuver and the provocative maneuvers of MC flexion and extension tests to confirm diagnosis of CMC osteoarthritis. 相似文献16.

Background
We hypothesized that medical experts would concur the American College of Surgeons/Association for Surgical Education Medical Student Simulation-based Surgical Skills Curriculum (“ACS/ASE Curriculum”) could be used to teach and assess Entrustable Professional Activities (EPAs).Methods
A “crosswalk” was created between ACS/ASE Curriculum modules and eight EPAs. Medical education experts participated in a Delphi process regarding feasibility of using the modules for teaching and assessing EPAs.Results
Twenty-eight educators from six clinical fields participated. There was consensus that five of the EPAs could be taught and assessed by the ACS/ASE Curriculum. A median of nine hours per month outside the surgical clerkship was recommended for skills training.Conclusions
The ACS/ASE Curriculum lays the framework for implementing select EPAs into medical student education. Experts recommended increased time for skills training with incorporation of the modules into the first three years of medical education, with assessments planned in the third to fourth years. 相似文献17.

Case report.Introduction
Development of extensor tendon adhesions is a common complication after intra-articular metacarpal head fracture. Whenever these adhesions cannot be mobilized by rehabilitation, tenolysis should be considered. However, the decision for tenolysis is often delayed. When the rehabilitation program comes to a plateau and clinical examination may not be sufficient to find out the cause, dynamic ultrasound (US) can show where the gliding mechanism is disrupted and help clinicians to give an accurate decision for determining the next steps.Purpose of the Study
To determine the role of dynamic US during hand rehabilitation.Methods
A 22-year-old woman presented with a fifth metacarpal intra-articular head fracture. Ten days after the surgery (open reduction and internal fixation) the hand rehabilitation program was commenced. After the third week, the metacarpophalangeal (MP) joint range of motion (ROM) gradually diminished. Dynamic US near the level of fifth MP joint revealed diminished extensor tendon excursion and capsular thickening.Results
Considering physical and sonographic findings, surgical tenolysis and capsular release was planned. After surgery, the DIP, PIP and MP joints reached full passive ROM.Conclusion(s)
Ultrasound is a quick and practical way to diagnose tendon adhesions. With this report, the authors suggest that clinicians may use dynamic US, especially in times when the patient comes to plateau during hand rehabilitation.Level of Evidence

Aims
Variations of the anatomy of donor hepatic arteries increase the number of arterial anastomoses during liver transplantation and, possibly, the incidence of hepatic artery thrombosis (HAT). In this study, we describe the arterial anatomic variations in liver grafts procured and transplanted by a single center in Greece, the techniques of arterial anastomosis, and their effect on the incidence of early HAT.Materials and Methods
From January 2013 to December 2017, the arterial anatomy of 116 grafts procured for liver transplantation were recorded, as well as the technique of arterial anastomosis and the incidence of early hepatic artery thrombosis (HAT <30 days).Results
A single hepatic artery was recorded in 72.41% of the procured grafts, an aberrant left hepatic artery (accessory or replaced) in 18 grafts (15.52%), and an aberrant right hepatic artery (accessory or replaced) in 17 grafts (14.66%), while other variations were observed in less than 1% of the procured livers. Of the 116 primary liver transplantations, 6 patients (5.17%) developed early HAT <30 days. Two of these patients (1.72%) had 1 anastomosis of the hepatic artery and 4 (3.45%) had 2 anastomoses due to anatomic variations.Conclusions
Anatomic variations of the hepatic artery in liver grafts is a common finding and increase the incidence of early HAT but not to a degree to make these grafts unusable. 相似文献19.
Purpose
Reduction and fixation in femoral neck fracture in young patients have a problem of nonunion requiring additional procedure like valgus osteotomy but fixation devices are technically difficult for inexperienced surgeons. We aims to assess the results of valgus osteotomy in femoral neck fracture in our setup.Methods
We report a series of 20 patients of higher Pauwel's angled fracture of femoral neck fracture presenting late wherein for valgus osteotomy was added to reduction fixation secured with a commonly available 135° dynamic hip screw and plate.Results
Femoral neck fractures united in 16 patients (80%). Excellent to good results (Harris hip score >80) were seen in 70% patients. Angle of correction of preoperative Pauwels has been changed from 68.3 to 34.3.Conclusion
135° dynamic hip screw and plate provides rigid internal fixation after valgus osteotomy and being a more familiar fixation device simplifies the procedure with good results. 相似文献20.
