Local Wound Infiltration With 0.5% Levobupivacaine for Postoperative Pain After Laparoscopic Colorectal Surgery.

ABSTRACT: The study design is a prospective randomized, double-blind, controlled trial of patients who are due to have elective laparoscopic colorectal surgery in Ramathibodhi Hospital. The primary objective is to measure pain scores (Visual Analog Scale) in the postoperative period. The secondary objective is to compare the VAS scores between the two types of technique used for specimen retrieval incision.After approval by the ethics committee, patients scheduled for elective laparoscopic colorectal surgery under general anesthesia who are eligible for inclusion criteria were recruited for this study after informed consent by surgical residents or surgical staff at the Outpatient Department (OPD). Patients who meet the exclusion criteria will be excluded.

Project description:Using Human WG CodeLink microarrays, we established the expression profiling of 26 LARC without metastasis to gain insight into the molecular signatures associated with response to treatment after CRT. The study initially included a total of 35 consecutive patients with locally advanced rectal cancer (LARC) treated at Virgen de las Nieves Hospital from 2008 until 2010. Written informed consent was obtained from all the patients, and the study protocol was approved by the local Clinical Research (Ethics) Committee. They were distributed in two subgroups following a histological classification of response to treatment. Pretherapeutic staging was performed, including complete medical history and physical evaluation, digital rectal examination, endorectal ultrasound, rigid rectoscopy, colonoscopy, PET/TC and chest x-ray. Tumor samples were prospectively obtained during the rectoscopy. All patients subsequently received a total dose of 50.4Gy of radiatio (28 fractions of 1.8Gy) associated with capecitabine or capecitabine and oxaliplatine. Standardized surgery was performed, including total mesorectal excision, after an interval of 8 weeks after chemoradiotherapy. Tumor response was assessed in surgical specimen by semi-quantitative pathological examination (regression grade) including UICC stage. Histopathological tumor regression was graded based on the semiquantitative 5 point tumor regression grading (TRG) system: TRG1 or a TRG2 scores were considered Responders, whereas TRG3, TRG4, and TRG5 scores were classified as Non-Responders. In addition, the tumor regression or radiotherapy effects were assessed by positron emission tomography (18F-FDG PET). Tumor samples of LARC were collected from 35 patients. Nine patients were finally excluded due to the poor quality of the RNA or contradictory results of MandardM-BM-4s criteria and histopathological downstaging, resulting a total of 26 patients. Complete clinical data regarding, age, sex, stage of disease, response to therapy, and overall survival from 26 patients (10 responders and 16 non-responders) was provided in the sample characteristics field. CRT: Chemoradiation; Cap: Capecitabine; Capox: Capecitabine and Oxaliplatine; cTN: clinical stage; Surg: surgical technique; LAR: Low anterior resection; APR: Abdmino-perineal resection; HART: Hartmann, TRG: Tumor Regression Grade; Downst: Downstaging; Downs: downsizing, Resp: response, CPR: complete pathologic response

Project description:Sacrocolpopexy has been dubbed the “gold standard” repair for apical pelvic organ prolapse (POP). This study sought to determine a genetic cause for sacrocolpopexy failure by comparing genotypes from 10 women who suffered from early POP reoccurance after sacrocolpopexy surgery, versus 40 randomly selected women with long term success after the same procedure. We objectively defined early overt failure after robotic-assisted laparoscopic sacrocolpopexy as having a pelvic organ prolapse quantification system examination (POP-Q) of stage III or IV occurring in more than one compartment within six months after surgery. All medical records identified during this process were then reviewed by a panel of urogynecology attendings and fellows to select patients who were truly clinical outliers. By this method we identified 10 patients (cases) who experienced early overt surgical failure. We also randomly selected 40 controls from our research database which includes greater than 500 patients who underwent robotic-assisted laparoscopic sacrocolpopexy during the same time period and had been objectively and subjectively assessed for ≥ 12 months with surgical success at ≥ 12 months that did not undergo prolapse re-operation or re-treatment. Demographics and peri-operative details were compared between cases and controls. Exclusion criteria for controls included use of other graft material besides polypropylene mesh, prior surgery for prolapse involving graft material, and conversion to laparotomy. DNA from the 10 cases and 40 controls was isolated from buccal swabs and genotyped on a single nucleotide polymorphism (SNP) array that contains 250,000 markers (NspI 250K SNP array, Affymetrix, Santa Clara, CA). All women in this study identified as Caucasian. All subjects provided written informed consent to study participation and data release. This was a case-control study approved by the Institutional Review Board at the Atlantic Health System in Morristown New Jersey (R11-10-004).
