Ovarian inguinal hernia.

INTRODUCTION: Gynaecological structures such as the ovaries, fallopian tubes, ligaments and uterus are rarely encountered inside a hernial sac. The prevalence of groin hernias containing parts of female genitalia remains unknown. The aim of this review was to summarise the existing evidence on inguinal hernias containing ovaries with or without the other female adnexa. METHODS: A systematic search was conducted for literature published up to February 2018 using the MEDLINE®, Scopus® and Google Scholar™ databases along with the references of the full-text articles retrieved. Papers on observational studies and case reports concerning women who were diagnosed with an ovarian inguinal hernia (pre or intraoperatively) were considered eligible for inclusion in the review. RESULTS: Fifteen papers (13 case reports, 2 case series) comprising seventeen patients (mean age 47.9 years) were evaluated. A left-sided hernia was noted in 13 cases (77%) whereas 4 patients had a right-sided hernia. Eight patients underwent preoperative imaging with computed tomography, ultrasonography or both. This was diagnostic in five cases. In 11 patients, hernia contents were repositioned, 2 had a salpingo-oophorectomy and 2 an oophorectomy. Eight patients underwent hernia repair with mesh placement while three had a herniorrhaphy. CONCLUSIONS: Ovarian inguinal hernias should be considered among the differential diagnoses of a groin mass or swelling. In women of reproductive age, repair of the hernia with the intent to preserve fertility is of critical importance.

Contamination of the Preservation Solution in Solid Organ Transplantation.

INTRODUCTION: Preservation solutions (PS), in which grafts for patients undergoing liver transplantation are stored, represent a medium suitable for microorganism growth and a potential source for transmission of pathogenic germs to the transplant recipients. The aim of the present study was to review the relevant literature for the incidence and predictors of positive microbiological findings in the PS. PATIENTS AND METHODS: We performed a literature review of publications on bacterial and fungal contamination of PS during cold organ storage focusing on its impact on bacteremia and/or nosocomial infection of the recipient. RESULTS: Overall 19 studies were reviewed, published between the years 2000 and 2016, that encompassed a total of 5647 patients. Positive cultures were identified in 1428 patients (25%). The documentation of bacteremia showed a wide deviation with documented ranges between 0% and 69%. Data on the identification of same species or of related nosocomial infections were only sparsely available; same species were found in a rate of 0% to 8%, and nosocomial infections were attributed to them in an incidence of 0% to 19%. CONCLUSIONS: Our study underlines both the limited published data and the contradictory available information on contamination of preservation solution in solid organ transplantation, not allowing for any recommendations. The necessity for prospective, multicentric studies on this topic is mandatory.

Liver Transplantation for Giant Hepatic Hemangioma: A Systematic Review.

INTRODUCTION: Despite their benign nature, liver hemangiomas (LH) are lesions that can cause major complications requiring intervention. Liver transplantation (LT) has been suggested as an effective treatment option in selected patients with giant LHs causing severe symptoms and cannot be treated otherwise. The aim of our study was to investigate the indications, aspects and post-operative outcomes of patients with a LH who underwent LT. MATERIALS AND METHODS: A meticulous search of the literature was performed. Studies presenting cases of LT due to LH were evaluated. Studies presenting patients characteristics and symptoms, aspects of the disease, transplantation indications and details were selected. RESULTS: Fifteen studies were included in the present review that involved 16 patients. Among them, 4 were male while the remaining 12 were female with a mean age of 39.9 ± 8.7 years. The main indications for LT included respiratory distress, massive hemorrhage, Kasabach-Merritt syndrome, and unsuccessful previous treatment strategies. Four patients were transplanted from living donors and the remaining 12 from cadaveric donors. No post-operative deaths were reported and all patients returned to normal activity. No deaths during the long-term follow-up were reported. CONCLUSIONS: LH is an extremely rare indication for LT. Nevertheless, the currently available data suggest that LT is a safe and efficient treatment in the management of symptomatic or complicated LH in selected patients.

Comparison Between Salvage Liver Transplantation and Repeat Liver Resection for Recurrent Hepatocellular Carcinoma: A Systematic Review and Meta-analysis.

INTRODUCTION: Repeat liver resection (RLR) has been adopted by surgeons as the first-line treatment in the case of intrahepatic recurrence of hepatocellular carcinoma (HCC), whereas salvage liver transplantation (SLT) is considered a second-line option. The aim of our study was to evaluate the results of SLT and RLR for HCC. METHODS: We searched for articles published up to December 1, 2017, in the PubMed database that compared SLT with RLR for HCC. We extracted data about patient and tumor characteristics, operative and postoperative outcomes, and survival and performed a meta-analysis. RESULTS: Patients who underwent SLT had somewhat larger liver lesions (mean difference: 0.73 cm, 95% confidence interval [CI]: 0.29-1.18, P = .001; I2: 0%, P = .82). Moreover, salvage liver transplantation resulted in higher blood loss, longer operating time, longer hospital stay, and higher postoperative morbidity (risk ratio [RR]: 2.45, 95% CI: 1.6-3.75, P < .0001; I2: 0%, P = .58) than RLR, whereas there was no significant difference in terms of postoperative mortality (RR: 6.48, 95% CI: 0.51-82.54, P = .15; I2: 61%, P = .08). On the other hand, SLT led to longer disease-free survival (DFS) than RLR (HR: 0.42, 95% CI: 0.25-0.7, P = .0009; I2: 63%, P = .03), but there was no significant difference in regard to overall survival (OS) (HR: 0.82, 95% CI: 0.55-1.23, P = .34; I2: 0%, P = .62). CONCLUSIONS: SLT seems to be inferior to RLR regarding operative and postoperative results but presents a significant advantage in terms of DFS over RLR.

Liver Transplantation for Wilson's Disease in Non-adult Patients: A Systematic Review.

INTRODUCTION: Wilson's disease (WD) is a rare autosomal recessive disorder transmitted through a gene located on chromosome 13. Liver transplantation (LT) provides a therapeutic option for patients with WD presenting fulminant liver failure or drug resistance. LT in patients with WD has a twofold aim: to save the patient's life when the disorder has progressed to hepatic (or other organ) failure and to cure the underlying metabolic defect. The aim of our study was to investigate the indications, aspects and post-operative outcomes in pediatric patients (< 18 years old) with WD who underwent LT. METHODS: A meticulous search of the literature since 1971 was performed. A retrospective analysis of all the studies, presenting cases of LT in children due to WD, was conducted. Studies that did not report patients' characteristics, transplantation indications, post-operative outcomes, and complications, as well as those with small study populations (< 10 patients), were excluded. RESULTS: Six studies were included in the present review, which involved 290 children. The main indications for LT included chronic liver failure and fulminant liver failure. The average 1-year survival rate was 91.9%, while the average 5-year survival rate was 88.2%. Retransplantation was performed in 16 patients due to transplant rejection. In general, patients transplanted for WD displayed an excellent quality of life after LT. CONCLUSION: LT is a safe and efficient procedure in selected pediatric patients with WD, demonstrating excellent long-term outcomes and quality of life.

Pregnancy Outcomes After Liver Transplantation: A Systematic Review.

PURPOSE: Liver transplantation (LT) constitutes a major therapeutic option for a number of patients suffering from liver pathologies. Pregnancy outcomes in patients who have undergone LT are assessed by a number of studies. The aim of our systematic review was to present the currently available evidence concerning the results of pregnancy in patients with LT. MATERIALS AND METHODS: A meticulous systematic search of the literature published before September 2017 for studies relevant in this field was conducted. All studies, which presented obstetric and maternal outcomes of patients with prior LT, were included. RESULTS: Nineteen studies, which comprised 1290 pregnancies in 885 female LT recipients, were reviewed. A total of 1014 live births were recorded, and the incidence of spontaneous abortions ranged from 0.5% to 33.3%. Concerning live births, a proportion of 32% of pregnancies resulted in preterm births (345 preterm births in 1079 pregnancies, range 0%-39%), and in 16% of pregnancies preeclampsia was reported (188 cases from 1173 pregnancies, range 2%-33.3%). The most commonly administered immunosuppressive drugs were cyclosporine and tacrolimus alone or with steroids. Cesarean section rates ranged from 20% to 67.9% among the included studies, concerning live birth. Moreover, approximately one-third of them resulted in preterm birth. Spontaneous abortions were reported in 176 cases (range: 0.5%-33.3%), and preeclampsia occurred in 188 patients (range: 2%-33.3%). CONCLUSION: Pregnancy outcomes from the included studies are encouraging, nonetheless pregnant patients who have undergone LT are at high risk and therefore require close monitoring by a multidisciplinary team.

The impact of subcutaneous tissue suturing at caesarean section on wound complications: a meta-analysis.

BACKGROUND: Caesarean wound complications are frequently observed in everyday practice. OBJECTIVES: To study whether subcutaneous tissue closure following caesarean section results in decreased wound complications. SEARCH STRATEGY: We systematically searched Medline (1966-2016), Scopus (2004-2016), ClinicalTrials.gov (2008-2016) and Cochrane Central Register of Controlled Trials CENTRAL (1999-2016) databases together with reference lists from included studies. SELECTION CRITERIA: Randomised and quasi-randomised trials that investigated the impact of subcutaneous tissue suturing on wound complications following caesarean section were held eligible for inclusion. Retrospective studies and prospective nonrandomised studies were excluded from the present meta-analysis. DATA COLLECTION AND ANALYSIS: The methodological quality of studies was assessed with the Jadad scale. Statistical meta-analysis was performed with the RevMan 5.3 software. MAIN RESULTS: Ten studies were finally included in our meta-analysis, which involved 3696 women delivered by caesarean section. Re-approximation of the subcutaneous tissue significantly reduced the odds of developing any type of wound complication [3811 women, random effects model (REM), odds ratio (OR) 0.66, 95% CI 0.47-0.93]. The incidence of seroma was also decreased (1979 women, REM, OR 0.53, 95% CI 0.33-0.84). On the other hand, the incidence of haematoma remained unaffected by subcutaneous closure (1663 women, REM, OR 0.74, 95% CI 0.22-2.42) as well as the likelihood of developing a wound infection (1971 women, REM, OR 0.99, 95% CI 0.70-1.41). CONCLUSIONS: The results of our meta-analysis suggest that subcutaneous tissue closure may benefit women undergoing caesarean section. Current data in women with high body mass index remain very limited; hence, definitive conclusions are precluded for this specific group. TWEETABLE ABSTRACT: Subcutaneous tissue closure may benefit women undergoing caesarean section.

The impact of obesity on cervical cerclage efficacy: A systematic review of the literature.

BACKGROUND: Cervical cerclage is a commonly applied procedure which is used as a preventive measure against preterm births among women with a short cervix (<25mm) or with previous painless mid-trimester pregnancy losses. The purpose of the present study is to evaluate whether the presence of maternal obesity reduces the efficacy of cervical cerclage. MATERIALS AND METHODS: We searched Medline (1966-2015), Scopus (2004-2015), Popline (1974-2015) and ClinicalTrials.gov (2008-2015) along with reference lists of electronically retrieved studies. RESULTS: Three studies were included in our review which involved 606 women. Among them 210 were obese (BMI>30 kg/m2) and 47 morbidly obese (BMI >40 kg/m2). The presence of obesity among women who had a cervical cerclage due to ultrasound or history indications did not seem to affect the gestational age at delivery or the neonatal birthweight. Furthermore, according to the findings of a single study it did not seem to reduce the gestational latency period in days (normal weight group 24.3±3.2, overweight group 21.1±5.1, obese group 21.4±4.9 p = 0.171). CONCLUSION: According to the findings of our systematic review obesity does not influence the efficacy of cervical cerclage. However, firm results are precluded due to the small number and the methodological heterogeneity of existing studies. Further, studies are needed to corroborate our findings.
