Given that there is variable diameter in the shale gas plunger lift wellhead, which causes cannot run up and down well affects effect of drainage production, paper carries out research on liner tube without wellhead installation methods, makes consistent with oil pipe, ensure can be open Christmas tree, facilitate periodic inspection replacement operation plunger, reduces cost salvage operation...

Abstract Aim There are various surgical options for the management of thumb carpometacarpal joint (CMCJ) arthritis. These include first metacarpal osteotomy, trapeziectomy with or without ligament reconstruction, CMCJ arthrodesis and arthroplasty. However, if these operations fail, salvage limited. The authors aim to offer ‘first second (FSMA)’ as a procedure failed CMC surgeries. also reviewed...

OBJECTIVE To determine the incidence of minor and major complications in patients with squamous cell carcinoma of the upper aerodigestive tract who require surgical salvage or planned neck dissection after an initial treatment regimen with radiotherapy or concurrent chemoradiotherapy for organ preservation. DESIGN The medical records of 100 patients treated in a phase 3 trial comparing radiot...

BACKGROUND The optimal timing of salvage androgen deprivation therapy (ADT) for biochemical recurrence after radical prostatectomy is controversial. We compared the outcomes of ultra-early versus early salvage ADT. METHODS Among 855 patients undergoing radical prostatectomy at our institution between 2000 and 2012, we identified 121 with adjuvant-treatment-naïve pT2-4N0M0 prostate cancer who ...

INTRODUCTION The Authors reports their experience with the use of femoro-femoral cross-over bypass graft in the management of acute lower limb ischaemia. PATIENTS AND METHODS Fourteen femoro-femoral bypass graft were performed for acute lower limb ischaemia due to unilateral thrombosis of iliac and femoral artery in 8 cases, late unilateral occlusion of a branch of previous aortobifemoral byp...

The present study investigated clinical outcomes and prognostic factors of patients with locally advanced synchronous esophageal squamous cell carcinoma (ESCC) and head/neck squamous cell carcinoma (HNSCC) receiving curative concurrent chemoradiotherapy (CCRT), and determined whether synchronous ESCC/HNSCC patients had worse prognosis compared to isolated ESCC patients. Using propensity score m...
