Micropuncture Access Set Use During Implantation of Totally Implantable Venous Access Device May Reduce Upper Extremity DVT Incidence Among Patients Undergoing Chemotherapy for Colorectal Cancer

Background

The aim of this study was to compare the perioperative outcomes when using a micropuncture access set (MS) to those when using a conventional puncture set (CS) for implantation of totally implantable venous access device (TAVID).

Methods

A total of 314 patients undergoing chemotherapy for colorectal cancer were included between June 2015 and July 2018. Of these, 123 (39.2%) received TAVID implantation using MS and 191 patients (60.8%) received TAVID using CS. Perioperative outcomes and complications were compared between both groups.

Results

Baseline characteristics, including body mass index, American Society of Anesthesiologists score, cardiovascular disease, diabetes mellitus, and hyperlipidemia, were not significantly different between the groups. Postoperative complications occurred in 25 patients (8.0%), and the rate and incidence of venous thrombosis were significantly higher in the CS group. There were no significant differences between the groups in other complications such as the rate of port site infection, deep vein thrombosis, obstruction, catheter dislocation, and skin complications (exposure). No incidence of catheter infection, port rotation, intraoperative bleeding, or pneumothorax was observed in this cohort.

Conclusions

MS is a safe and feasible procedure and results in less thrombosis. MS may play an important role in improving outcomes for the implantation of TAVID.

     

How to optimise urinary continence in anatomical endoscopic enucleation of the prostate?

The traditional transurethral resection of the prostate (TURP) is considered as gold-standard surgical treatment to relieve symptoms resulting from bladder outlet obstruction by prostate enlargement. However, with the advances of novel laser technologies and more experienced surgeon conquering the steep learning curve, anatomical endoscopic enucleation of prostate (AEEP) has become a more popular alternative surgical technique. Although AEEP has compatible functional outcome, less blood loss, shorter catheterisation duration and hospital stay, the risk of post-operative urinary incontinence (UI) is often an issue of concern. In this review, we focus on discussion about risk factors related to increased incidence of UI, some surgical tips to avoid damaging external urinary sphincter and treatment strategies to facilitate recovery of urinary continence after surgery.     

Inter-segmental foot kinematics during gait in elderly females according to the severity of hallux valgus

The objective of this study was to find the effect of hallux valgus (HV) deformity on the inter-segmental motion of the foot using an MFM with a 15-marker set (DuPont Foot Model, DuFM) in comparison with age and sex controlled healthy adults. Fifty-eight female symptomatic HV patients and 50 female asymptomatic older female volunteers were included in this study. According to the radiographic hallux valgus angle (HVA), the study population was divided into severe HV (SHV, HVA ≥ 40°, n = 25), moderate HV (MHV, 20° ≤ HVA < 40°, n = 47), and control (CON, n = 36). MHV group was divided into symptomatic MHV group (S-MHV, n = 33) and asymptomatic MHV group (A-MHV, n = 14) according to the symptoms associated with HV. For temporal parameters, gait speed and stride length were diminished according to the severity of HV deformity. Sagittal range of motion of hallux and hindfoot decreased significantly in SHV group. Loss of push-off during the preswing phase was observed and forefoot adduction motion during terminal stance was decreased in SHV group. In a subgroup analysis of MHV, asymptomatic HV minimally affects gait and inter-segmental motion during gait. HV deformity affects gait parameters and inter-segmental motion of the foot during gait in proportion to the severity of the deformity. However, the effect of MHV itself on foot kinematics might be limited while pain or arthritic change of the joint might cause changes in gait in patients with symptomatic HV.     

Intratumoral extramedullary hematopoiesis in solitary fibrous tumor of the breast

Extramedullary hematopoiesis (EMH) is most often associated with underlying hematologic disorders, such as myeloproliferative neoplasms and thalassemia. EMH in the setting of solitary fibrous tumor (SFT) is exceedingly rare, with only 3 cases reported to date in the English literature. Herein, we describe our experience with a unique case of SFT arising in the breast with intratumoral foci of EMH in a 57‐year‐old woman who presented with an incidentally found right axillary mass on routine screening mammography. To the best of our knowledge, this is the first reported case of mammary SFT with concurrent intratumoral EMH.
