The aim of this study was to assess the clinical and laboratory correlations of bone mineral density (BMD) measurements among a large population of patients on chronic peritoneal dialysis (PD). This cross-sectional, multicenter study was carried out in 292 PD patients with a mean age of 56 +/- 16 years and mean duration of PD 3.1 +/- 2.1 years. Altogether, 129 female and 163 male patients from 24 centers in Canada, Greece, and Turkey were included in the study. BMD findings, obtained by dual-energy X-ray absorptiometry (DEXA) and some other major clinical and laboratory indices of bone mineral deposition as well as uremic osteodystrophy were investigated. In the 292 patients included in the study, the mean lumbar spine T-score was -1.04 +/- 1.68, the lumbar spine Z-score was -0.31 +/- 1.68, the femoral neck T-score was -1.38 +/- 1.39, and the femoral neck Z score was -0.66 +/- 1.23. According to the WHO criteria based on lumbar spine T-scores, 19.2% of 292 patients were osteoporotic, 36.3% had osteopenia, and 44.4% had lumbar spine T-scores within the normal range. In the femoral neck area, the prevalence of osteoporosis was slightly higher (26%). The prevalence of osteoporosis was 23.3% in female patients and 16.6% in male patients with no statistically significant difference between the sexes. Agreements of lumbar spine and femoral neck T-scores for the diagnosis of osteoporosis were 66.7% and 27.3% and 83.3% for osteopenia and normal BMD values, respectively. Among the clinical and laboratory parameters we investigated in this study, the body mass index (BMI) (P < 0.001), daily urine output, and urea clearance time x dialysis time/volume (Kt/V) (P < 0.05) were statistically significantly positive and Ca x PO(4) had a negative correlation (P < 0.05) with the lumbar spine T scores. Femoral neck T scores were also positively correlated with BMI, daily urine output, and KT/V; and they were negatively correlated with age. Intact parathyroid hormone levels did not correlate with any of the BMD parameters. Femoral neck Z scores were correlated with BMI (P < 0.001), and ionized calcium (P < 0.05) positively and negatively with age, total alkaline phosphatase (P < 0.05), and Ca x P (P < 0.01). The overall prevalence of fractures since the initiation of PD was 10%. Our results indicated that, considering their DEXA-based BMD values, 55% of chronic PD patients have subnormal bone mass-19% within the osteoporotic range and 36% within the osteopenic range. Our findings also indicate that low body weight is the most important risk factor for osteoporosis in chronic PD patients. An insufficient dialysis dose (expressed as KT/V) and older age may also be important risk factors for osteoporosis of PD patients.
This systematic review and meta-analysis of retrospective studies indicates that the use of perioperative chemical thromboprophylaxis reduces VTE incidence following liver surgery without an apparent increased risk of bleeding.
BackgroundMinimally invasive incisional hernia repair has been established as a safe and efficient surgical option in most centres worldwide. Laparoscopic technique includes the placement of an intraperitoneal onlay mesh with fixation achieved using spiral tacks or sutures. An additional step is the closure of the fascial defect depending upon its size. Key outcomes in the evaluation of ventral abdominal hernia surgery include postoperative pain, the presence of infection, seroma formation and hernia recurrence. TACKoMESH is a randomised controlled trial that will provide important information on the laparoscopic repair of an incisional hernia; 1) with fascial closure, 2) with an IPOM mesh and 3) comparing the use of an articulating mesh-fixation device that deploys absorbable tacks with a straight-arm mesh-fixation device that deploys non-absorbable tacks.MethodsA prospective, single-centre, double-blinded randomised trial, TACKoMESH, will establish whether the use of absorbable compared to non-absorbable tacks in adult patients undergoing elective incisional hernia repair produces a lower rate of pain both immediately and long-term. Eligible and consenting patients will be randomized to surgery with one of two tack-fixation devices and followed up for a minimum one year. Secondary outcomes to be explored include wound infection, seroma formation, hernia recurrence, length of postoperative hospital stay, reoperation rate, operation time, health related quality of life and time to return to normal daily activity.DiscussionWith ongoing debate around the best management of incisional hernia, continued trials that will add substance are both necessary and important. Laparoscopic techniques have become established in reducing hospital stay and rates of infection and report improvement in some patient centered outcomes whilst achieving similarly low rates of recurrence as open surgical techniques. The laparoscopic method with tack fixation has developed a reputation for its tendency to cause post-operative pain. Novel additions to technique, such as intraoperative-sutured closure of a fascial defect, and developments in surgical technology, such as the evolution of composite mesh design and mesh-fixation devices, have brought about new considerations for patient and surgeon. This study will evaluate the efficacy of several new technical considerations in the setting of elective laparoscopic incisional hernia repair.Trial registrationName of registry - ClinicalTrials.gov Registration number: NCT03434301.

Introduction: Evolution in laparoscopic liver surgery during the past two decades is an indisputable fact. According to the second international consensus conference for laparoscopic liver resection held in Morioka, Japan in 2014 major resections are still regarded as innovative procedures in the exploration phase. On this basis, our study aims to explore the efficacy and safety of laparoscopic vs. open major liver resection and therefore increase the existing evidence on major laparoscopic liver surgery. Methods: All consecutive patients who underwent major liver resection, open and laparoscopic from January 2016 to May 2018 were identified from our prospectively maintained database. Propensity score matching analysis was performed using R statistical tool in SPSS to isolate matched open and laparoscopic cases which were compared for intraoperative and postoperative short-term outcomes. Lotus ultrasonic energy device was used for parenchymal transection in laparoscopic cases vs. CUSA in open procedures. Results: Propensity score matching analysis was performed on 82 consecutive patients (61 open and 21 laparoscopic major hepatectomies) resulting in 40 matched patients, 20 in each group. The mean total duration of surgery and duration of parenchymal transection were slightly longer in the laparoscopic group ( p = 0.419, p = 0.348). There was no difference in the intraoperative and postoperative transfusion rates. Patients after laparoscopic surgery were discharged 2 days earlier on average ( p = 0.310). No difference was observed in complication rates and mortality. Conclusion: Our data did not reveal inferiority of the laparoscopic major hepatectomy vs. the open approach in any parameter compared. The use of the Lotus ultrasonic energy device appeared to be efficient and safe for parenchymal transection in the laparoscopic procedures.
Result: On the patient Background, the number of males was significantly larger in group II (p=0.048), and the BMI was significantly lower in group I (p=0.012). Operation time was significantly shorter in group I than in group II (381AE87 vs. 442AE91min, p=0.002). The rate of pancreatic fistula grade B or C by ISGPF definition was no significant differences between two groups (16.7% vs. 15.2%, p=0.571). The serum CRP values on the 3rd and 7th postoperative days were significantly lower in group I, but there was no difference between duration of drain insertion (10.3AE14.1 vs. 11.4AE14.1 days, p=0.697) and postoperative hospital stay (18.2AE14.3 vs. 20.4AE17.3 days, p=0.275). Conclusions: Postoperative drainage management in PD could be done with only one drainage tube. Single drainage seemed to be feasible, suggesting the possibility of suppressing postoperative inflammation.
individual HPB surgeon (AKS) in a regional liver surgery service. 22 underwent hepatectomy for type III or type IV PH-CCA and constitute the study population of this report. Patients undergoing surgery for intra-hepatic cholangiocarcinoma are excluded. Pre-operative preparation included percutaneous trans-hepatic drainage of the future liver remnant followed by cardiopulmonary exercise testing and CT of the abdomen and thorax. Vascular involvement was assessed by pre-operative contrast-enhanced magnetic resonance scan. No patients underwent staging laparoscopy. Results: 8 (36%) were IIIa, 7 (32%) were IIIb and 7 were type IV. All underwent major hepatectomy with 4 (18%) requiring arterial reconstruction to the new remnant liver. During the study period 1 further patient (1 of 23) underwent non-therapeutic laparotomy (4%) because of nodal involvement in stations 8 and 9. Histology confirmed an R0 resection margin in 15 (68%). Conclusions: As with other single centre reports this is a highly selected series and care must be exercised when extrapolating from these results. However, the data question the dogma of routine pre-operative staging laparoscopy prior to resection of PH-CCA.
