Oral celecoxib versus oral diclofenac for post-perineal repair analgesia after spontaneous vaginal birth: a randomised trial

OBJECTIVE: To compare oral celecoxib with oral diclofenac as pain reliever after perineal repair following normal vaginal birth. METHODS: One hundred and sixty-four and 165 women, respectively, were randomised to 200 mg celecoxib or to 100 mg diclofenac orally 12 hourly for 24 h after perineal repair. A ten-point visual analog scale (VAS) for pain recorded at one, two, four, eight, 12 and 24 hours at rest and when mobilising was the primary outcome. RESULTS: Repeated measures analysis of variance showed a larger reduction of VAS pain score at rest with celecoxib compared to diclofenac (P = 0.044). Mean VAS pain score at rest was 2.2 versus 2.7, 2.1 versus 2.5, 1.8 versus 2.2, 1.6 versus 1.6, 1.3 versus 1.4 at one, two, four, eight, 12 and 24 hours, respectively, for celecoxib versus diclofenac. The difference in pain score when mobilising was not significant (P = 0.75). Univariate analyses with the Student's t-test indicated significantly lower pain score at rest only at one, two and four hours with celecoxib. Randomisation to celecoxib was associated with less upper gastrointestinal symptoms reported: 38 of 163 (23.3%) versus 57 of 165 (34.5%) (relative risk 0.67 95% CI 0.48-0.96: P = 0.029) but additional analgesia for breakthrough pain was not significantly different eight of 161 (5.0%) versus 18 of 165 (10.9%) (relative risk 0.46 95% CI 0.20-1.01: P = 0.065). CONCLUSION: Celecoxib was associated with a slightly lower VAS pain score at rest and less upper gastrointestinal symptoms were reported when compared to diclofenac.     

Urologic complications of laparoscopic radical hysterectomy and lymphadenectomy

Introduction and hypothesis

The purpose of this study was to evaluate the intra- and postoperative urologic complications and management in patients with cervical or endometrial cancer treated with laparoscopic radical hysterectomy and lymphadenectomy.

Methods

We retrospectively reviewed the medical records of 146 patients with cervical or endometrial cancer who underwent total laparoscopic radical hysterectomy with lymphadenectomy between August 2002 and April 2011. The intra- and postoperative urologic complications were analyzed.

Results

Double ureteral stents were inserted prophylactically in 13 patients (8.9?%), 2 of whom had postoperative urologic complications. Nine patients (6.2?%) had postoperative urologic complications. Of four patients with ureterovaginal fistulas, two were treated conservatively with cystoscopic placement of ureteral stents and two underwent ureteroneocystostomies. Vesicovaginal fistulas occurred in two patients, both of whom underwent vesicovaginal fistula repairs. One patient noted to have a bladder injury intraoperatively had a laparoscopic repair, and one patient noted to have a ureteral injury postoperatively was treated conservatively with cystoscopic placement of ureteral stents.

Conclusions

Iatrogenic lower urinary tract injuries during laparoscopic radical hysterectomy are relatively common complications. Intraoperative prophylactic ureteral stent insertion and the early detection of urologic complications postoperatively is advised for patients who undergo laparoscopic radical hysterectomies.     

Symptomatic venous thromboembolism in Asian colorectal cancer surgery patients

Background  

The occurrence of venous thromboembolism (VTE), manifesting as deep vein thrombosis (DVT) or pulmonary embolism (PE), after colorectal cancer surgery in Asian patients remains poorly characterized. The present study was designed to investigate the incidence of symptomatic VTE in Korean colorectal cancer patients following surgery, and to identify the associated risk factors.     

Platelet Function and Genotype after DES Implantation in East Asian Patients: Rationale and Characteristics of the PTRG-DES Consortium

PurposePlatelet function test (PFT) results and genotype hold unique prognostic implications in East Asian patients. The aim of the PTRG-DES (Platelet function and genoType-Related long-term proGnosis in Drug-Eluting Stent-treated Patients with coronary artery disease) consortium is to assess the clinical impact thereof on long-term clinical outcomes in Korean patients with coronary artery disease during dual antiplatelet therapy (DAPT) including clopidogrel.Materials and MethodsSearching publications on the PubMed, we reviewed clopidogrel treatment studies with PFT and/or genotype data for potential inclusion in this study. Lead investigators were invited to share PFT/genotype results, patient characteristics, and clinical outcomes to evaluate relationships among them.ResultsNine registries from 32 academic centers participated in the PTRG-DES consortium, contributing individual patient data from 13160 patients who underwent DES implantation between July 2003 and August 2018. The PTRG-PFT cohort was composed of 11714 patients with available VerifyNow assay results. Platelet reactivity levels reached 218±79 P2Y12 reaction units (PRU), and high on-clopidogrel platelet reactivity based on a consensus-recommended cutoff (PRU >208) was observed in 55.9%. The PTRG-Genotype cohort consisted of 8163 patients with candidate genotypes related with clopidogrel responsiveness. Of those with cytochrome P450 (CYP) 2C19 genotype, frequencies of carrying one and two loss-of-function allele (s) (^*2 or ^*3) were 47.9% (intermediate metabolizers) and 14.2% (poor metabolizers), respectively.ConclusionThe PTRG-DES consortium highlights unique values for on-clopidogrel platelet reactivity and CYP2C19 phenotype that may be important to developing optimal antiplatelet regimens in East Asian patients.Trial RegistrationClinicalTrials.gov Identifier: {"type":"clinical-trial","attrs":{"text":"NCT04734028","term_id":"NCT04734028"}}NCT04734028.     

Feasibility of Single-Stage Laparoscopic Resection After Placement of a Self-Expandable Metallic Stent for Obstructive Left Colorectal Cancer

BACKGROUND: The present study investigated the feasibility of a single-stage operation consisting of self-expandable metallic stent (SEMS) placement followed by laparoscopic surgery for obstructive left colorectal cancer. METHODS: From July 2002 to March 2007, 17 consecutive patients with primary obstructive left colorectal cancer underwent SEMS placement followed by laparoscopic surgery. Data were collected retrospectively regarding clinicopathological findings, SEMS placement, operative procedures, and perioperative outcomes. Technical success was defined as successful stent deployment across the obstructive lesion, and clinical success as the possibility of performing a single-stage operation without creating a stoma. RESULTS: In the laparoscopic group, the technical success rate was 100% (17/17) and there was no morbidity associated with SEMS placement. The median interval to laparoscopic surgery was 7 (range, 2-11) days, and the procedures included 11 anterior resections, 3 left hemicolectomies, 2 Hartmann's procedures, and 1 subtotal colectomy. All procedures were completed laparoscopically without conversion to open surgery. The median operating time was 178 (range, 93-377) minutes, and the median estimated blood loss was 100 (range, 50-400) ml with no cases requiring intraoperative transfusions. The clinical success rate was 82.4% (14/17), and there was no surgical morbidity other than two patients in whom chyloperitoneum and ileus were controlled by using conservative management. The median postoperative hospital stay was 9 (range, 7-49) days. CONCLUSIONS: A single-stage operation consisting of SEMS placement followed by laparoscopic surgery seems to be a feasible and safe treatment option for obstructive left colorectal cancer.     

Skeletal myoblast transplant in heart failure

Despite recent advances in the prevention and treatment of ischemic heart disease (IHD), treatment of patients with heart failure secondary to myocardial infarction remains a therapeutic challenge. Heart transplantation has emerged as a viable option but is fraught with problems of supply. Mechanical assist devices are extremely expensive and dynamic cardiomyoplasty has shown only limited success in the clinical setting. Recent insights into the pathogenesis of myocardial diseases and the progress made in the field of molecular biology have resulted in the development of new strategies at molecular as well as cellular levels for cardiac muscle repair. One such strategy is to augment ventricular function by means of cellular cardiomyoplasty through intracardiac cell grafting using adult and fetal cardiomyocytes, stem cells, and autologous skeletal myoblasts.     

Comparison of computer integrated patient controlled epidural analgesia vs. conventional patient controlled epidural analgesia for pain relief in labour

Computer integrated-patient controlled epidural analgesia (CI-PCEA) is a novel drug delivery system. It automatically titrates the background infusion rate based on the individual parturient's need. In this randomised trial, we compared the local anaesthetic consumption by parturients using CI-PCEA with demand only patient controlled epidural analgesia (PCEA) for labour analgesia. We recruited 40 parturients after approval by the ethics committee. Group PCEA (n = 20) received demand only PCEA. Group CI-PCEA (n = 20) received a similar PCEA regimen but the computer integration titrated the background infusion to 5, 10 or 15 ml x h(-1) if the patient required one, two or three demand boluses, respectively, in the previous hour. The background infusion decreased by 5 ml x h(-1) if there was no demand bolus in the previous hour. The sample size was calculated to show equivalence in local anaesthetic used. The time weighted consumption of local anaesthetic was similar in both groups (mean difference 0.7 mg x h(-1), 95% confidence interval [CI: -2.5, 1.1]; p = 0.425). The CI-PCEA group had higher maternal satisfaction scores: mean (SD) 93 (7) vs. 86 (11), p = 0.042. CI-PCEA does not increase the use of local anaesthetic when compared with demand only PCEA but does increase patient satisfaction.     

Laparoscopic-Assisted Combined Colon and Liver Resection for Primary Colorectal Cancer with Synchronous Liver Metastases: Initial Experience

BACKGROUND: Laparoscopic approaches have become increasingly used in selected patients with either colorectal or liver cancer. However, the feasibility of laparoscopic-assisted combined colon and liver resection in primary colorectal cancer with synchronous liver metastases remains unknown. The aim of the present study was to determine the feasibility of laparoscopic-assisted combined colon and liver resection for primary colorectal cancer with synchronous liver metastases. METHODS: Laparoscopic surgery involving intestinal anastomosis was performed for primary colorectal cancer. The liver was then mobilized with the assistance of a hand inserted through the upper midline incision. For minor resections, the parenchymal transection was performed laparoscopically. For major resection involving a hilar dissection, transection was performed according to the standard open techniques under direct vision through the incision. Resected specimens were retrieved directly through the midline incision. RESULTS: Ten patients with primary colorectal cancer and synchronous liver metastases underwent the above procedure between September 2006 and April 2007. Surgical procedures for colorectal cancer included 5 low anterior resections, 3 anterior resections, 1 right hemicolectomy, and 1 subtotal colectomy. Combined hepatic surgery included 6 major hepatectomies, 3 segmentectomies, and 1 tumorectomy. All procedures were successful, with no conversions to open surgery required. The median operation time was 439 min (range: 210-690 min), and the median estimated blood loss was 350 ml (range: 300-1,200 ml). There was no surgical mortality or major morbidity, except in one patient in whom postoperative bleeding at the site of para-aortic node dissection was promptly controlled. CONCLUSIONS: Laparoscopic-assisted combined colon and liver resection is a feasible and safe procedure for the treatment of primary colorectal cancer with synchronous liver metastases.
