No definitive treatment strategy has been established for patients with metastatic colorectal cancer (mCRC) who experienced progression after three or more lines of chemotherapy. A total of 36 mCRC patients were enrolled in this retrospective study who received apatinib therapy under non-clinical trial setting after progression in People's liberation army general Hospital from March 2015 and August 2017. Progression free survival (PFS), overall survival (OS), disease control rate (DCR), objective response rate (ORR) and treatment-related adverse events (AEs) were reviewed and evaluated...

Due to the hybrid warfare currently experienced by multiple NATO coalition and NATO partner nations, the tactical combat casualty care (TCCC) paradigm is greatly challenged. One of the major challenges to TCCC is the ad hoc extension phase in resource-poor environments, referred to as prolonged field care (PFC) and forward resuscitative care (FRC). The nuanced clinical skills with limited resources required by warfighters and auxiliary health care professionals to mitigate death on the battlefield and prevent morbidity and mortality in the PFC phase represent a balance that is still under review...

BACKGROUND: Colonic diverticulosis is one of the most common gastroenterological disorders. Although diverticulosis is typically benign, many individuals develop diverticulitis or other aspects of diverticular disease. Diverticulosis is thought to stem from a complex interaction of environmental, dietary, and genetic factors; however, the contributing genetic factors remain unknown. OBJECTIVE: The aim of our present study was to determine the role of genetic variants within genes encoding for collagens of the connective tissue in diverticulosis...

BACKGROUND: Data on temozolomide (TEM) and irinotecan (IRI) activity in recurrent Ewing sarcoma (EWS), especially in adult patients, are limited. METHODS: Patients receiving TEM 100 mg/m2 /day oral, and IRI 40 mg/m2 /day intravenous, days 1-5, every 21 days, were included in this multi-institutional retrospective study. Disease control rate (DCR) [overall response rate (ORR) [complete response (CR) + partial response (PR)] + stable disease (SD)], 6-months progression-free survival (6-mos PFS) and 1-year overall survival (OS) were assessed...

BACKGROUND: Advanced biliary tract cancers (BTCs) have a poor prognosis and limited treatment options. This exploratory phase II study aimed to evaluate the activity of the mTOR inhibitor everolimus in advanced BTC and explore prognostic biomarkers. METHODS: Patients with advanced BTCs, who had not received chemotherapy for advanced disease, were enroled to receive everolimus (10 mg daily). The primary endpoint was disease control rate (DCR) at 12 weeks. Secondary endpoints included overall response rate, progression-free survival (PFS), overall survival (OS) and adverse events...

BACKGROUND: Apprenticeship in training new surgical skills is problematic, because it involves human subjects. To date there are limited inanimate trainers for rectal surgery. OBJECTIVE: The purpose of this article is to present manufacturing details accompanied by evidence of construct, face, and content validity for a robotic rectal dissection simulation. DESIGN: Residents versus experts were recruited and tested on performing simulated total mesorectal excision...

BACKGROUND: Greater understanding of barriers to screening of colorectal cancer among lower socioeconomic, particularly Hispanic, patients is needed to improve disparities in care. OBJECTIVE: This study aimed to explore patients' perceptions and experiences of care seeking for colorectal cancer to identify barriers to early diagnosis and treatment. DESIGN: This explorative qualitative study was conducted as a focused ethnography of patients diagnosed with advanced-stage colorectal cancer...

BACKGROUND: The ideal management for fistula-in-ano would resolve the disease while preserving anal continence. OBJECTIVE: The purpose of this study was to determine the efficacy of draining seton alone in achieving resolution or significant amelioration of symptoms for patients with fistula-in-ano. DESIGN: This was a retrospective case series involving chart review and telephone interviews. A single colorectal surgeon performed surgeries between June 1, 2005, and June 30, 2014...

BACKGROUND: Despite the advantages of stapled hemorrhoidopexy reported in the literature in terms of postoperative pain, hospital stay, and duration of convalescence, it was described to have a higher recurrence rate compared with conventional hemorrhoidectomy. OBJECTIVE: The aim of this study was to evaluate clinical outcomes and patient satisfaction after stapled hemorrhoidopexy at 10-year follow-up. DESIGN: This was a retrospective cohort analysis conducted on prospectively collected data...

BACKGROUND: Complications from adhesions after intra-abdominal surgery accounts for ~6% of hospital admissions. Currently, hyaluronate/carboxymethylcellulose represents the main option to prevent postoperative adhesion formation. Human amniotic membrane contains inherent anti-inflammatory properties that mitigate adhesion formation. OBJECTIVE: This study aimed to evaluate adhesion generation after surgical trauma with amniotic membranes compared with standard intraperitoneal adhesion barriers...

BACKGROUND: The possible relationship between obesity and the risk of colonic diverticulosis has been suggested by recent epidemiologic studies, although the results were inconsistent. OBJECTIVE: This systematic review and meta-analysis was conducted to summarize all of the available data. DATA SOURCES: A comprehensive literature review was conducted using the MEDLINE and EMBASE databases through January 2017. STUDY SELECTION: Studies that compared the risk of colonic diverticulosis among subjects with obesity versus those without obesity were included...

BACKGROUND: Although colorectal cancer comprises several histological subtypes, the influences of histological subtypes on disease progression and treatment responses remain controversial. OBJECTIVE: We sought to evaluate the prognostic relevance of mucinous and poorly differentiated histological subtypes of colorectal cancer by the propensity score weighting analysis of prospectively collected data from multi-institute phase III trials. DESIGN: Independent patient data analysis of a pooled database from 3 phase III trials was performed...

BACKGROUND: Locally advanced colon cancer invading surrounding organs or structures is challenging to surgeons and oncologists. Multivisceral resections with tumor removal en bloc with invaded tissues provide the best chance for cure. OBJECTIVE: We aimed to assess the management and outcomes after multivisceral resections in patients with clinically infiltrative, locally advanced primary colon cancer. DESIGN: This is a descriptive retrospective cohort study...

BACKGROUND: The presence of main or lateral lymph node metastasis in colorectal cancer is classified as jN3 by the Japanese Society for Cancer of the Colon and Rectum. Whether information on jN3 status adds value to the TNM classification remains unclear. OBJECTIVE: We aimed to assess the prognostic relevance of colorectal cancer nodal staging through the Japanese jN3 categorization compared with that through TNM. DESIGN: This was a retrospective study...

BACKGROUND: The optimal surgical management of splenic flexure cancer is debated, partly because of an incomplete understanding of the lymphatic drainage of this region. OBJECTIVE: This study aimed to evaluate the normal lymphatic drainage of the human splenic flexure using laparoscopic scintigraphic mapping. DESIGN: This was a clinical trial. SETTINGS: The study was conducted at a single tertiary care center. PATIENTS: Thirty consecutive patients undergoing elective colorectal resections without splenic flexure pathology were recruited...

BACKGROUND: Rectal cancer outcomes have improved with the adoption of a multidisciplinary model of care. However, there is a spectrum of quality when viewed from a national perspective, as highlighted by the Consortium for Optimizing the Treatment of Rectal Cancer data on rectal cancer care in the United States.

BACKGROUND: Endoscopic dacryocystorhinostomies (eDCRs) show patency rates between 81% and 94%. However, dacryocystorhinostomy (DCR) failure and the need for revision remain a significant challenge. One of the principal challenges in revision eDCR is the need to surgically identify the correct osteotomy site and maintain long-term patency in the setting of previously instrumented and potentially scarred tissue. At the same time, the surgeon must assume that the blood supply to the commonly described anterior and posteriorly pedicled flaps has been compromised...
