Nonoperative Management of Leaks After Laparoscopic Sleeve Gastrectomy With Endoscopic Stents in a Tertiary Referral Center

BackgroundLaparoscopic sleeve gastrectomy (LSG) is a frequently performed operation. Leaks are formidable complications; however, the optimal management of these leaks is controversial.MethodsWe retrospectively reviewed the medical records of 15 patients referred to our tertiary center between 2012 and 2016 with leaks after LSG.ResultsIn 12 patients with whom ongoing leaks were identified, stents were inserted with the intent of definitive therapy. In addition to attempts at source control, percutaneous drainage was carried out for intraabdominal collection in 9 patients and pleural effusion in 4 patients. The length of stay in the intensive care unit was significantly shorter in patients referred earlier or in those without any intervention.ConclusionLSG leaks can be treated nonoperatively in well-organized centers under meticulously designed protocols, depending on the clinical condition of the patient.     

The clinical course of COVID-19 in hematopoietic stem cell transplantation (HSCT) recipients

Background/aim The disease caused by SARS-CoV-2 was named as COVID-19. There is as yet insufficient information about the effects of HSCT on the clinical course of COVID-19. In the present study, we aimed to investigate the clinical course of COVID-19 in patients who had undergone HSCT. Materials and methods We analyzed baseline characteristics, clinical course and findings of COVID-19, hospitalization and death rates, overall survival, and case fatality rates of HSCT recipients diagnosed with COVID-19 retrospectively. Results 57.6% of the patients underwent AHSCT, and 42.4% underwent allo-HSCT. 60.6%, 27.3%, and 12.1% of the patients had mild, moderate, and severe COVID-19 or critical illness, respectively. Overall, 45.5% were hospitalized, 12.1% required intensive care, and 9.1% necessitated invasive mechanical ventilation. The total CFR was 9.1% in HSCT recipients, 22.2% in patients with active hematologic malignancy, and 4.2% in patients without active hematologic malignancy. Conclusion It can be concluded that mortality of HSCT recipients is lower in patients whose primary disease is in remission compared to ones that are not in remission. Further studies with larger group patients are needed in order to delineate the effects of COVID-19 on HSCT patients.     

Embolization of peripheral vascular malformations with ethylene vinyl alcohol copolymer (Onyx)

PURPOSE: To demonstrate the feasibility and preliminary efficacy of endovascular embolization of peripheral congenital vascular malformations (VMs) with use of a nonadhesive liquid embolic agent, Onyx. MATERIALS AND METHODS: Nine patients with a mean age of 20.8 years had local low-flow (n = 4), local high-flow (n = 3), or diffuse high-flow (n = 2) VMs located in the upper or lower extremities. In all patients, endovascular embolization was performed via the superselective catheterization of arterial feeders of VMs with use of microcatheters in a coaxial technique. A total of 15 embolization procedures were performed with Onyx, which was composed of 6%, 8%, or 20% ethylene vinyl alcohol copolymer dissolved in dimethyl sulfoxide. RESULTS: In two of four patients with local low-flow VMs, the lesions were embolized completely. In the other two patients with local low-flow VMs, embolizations were incomplete. The remaining five high-flow lesions of local (n = 3) or diffuse (n = 2) types were also embolized incompletely. In all patients with local low-flow VMs and in one patient with a local high-flow VM, clinical signs and symptoms were resolved significantly. Other patients did show clinical benefit from embolization to varying degrees. CONCLUSION: In our experience in a limited number of cases, Onyx promises and provides important advantages over conventional embolic agents in the endovascular transcatheter embolization of congenital peripheral VMs. However, as with other embolic agents, it is far from perfect.     

Surgical conservation of both ovaries in an adolescent with uterine müllerian adenosarcoma: a case report

Fertility-sparing and minimally invasive surgeries are advancing everyday in gynecologic oncology. However, data on conservation of ovaries in uterine müllerian adenosarcoma are limited due to its very rare incidence in reproductive-aged females. Conservation of both ovaries along with adjuvant chemotherapy was performed in a 14-year-old girl with uterine adenosarcoma. After 30 months, she had no evidence of disease. Therefore, surgical conservation of ovaries might be a solution for fertility sparing in uterine müllerian adenosarcoma.     

Isolated Cortical Venous Thrombosis Associated With Intracranial Hypotension Syndrome

The association of intracranial hypotension syndrome with cerebral venous thrombosis is rare. We report our experience with isolated cortical venous thrombosis, which developed after unsuccessful epidural anesthesia. Magnetic resonance imaging showed characteristic imaging findings of intracranial hypotension syndrome, such as dural thickening and brain sagging. We also detected right parietal venous hemorrhagic infarction secondary to right-sided cortical venous thrombosis. After the treatment of intracranial hypotension via epidural blood patch, heparin was used to treat cortical venous thrombosis.     

Does premature luteinization or early surge of LH impair cycle outcome? Report of two successful outcomes

Purpose

To report two successful antagonist IVF cycles; one ending up with pregnancy despite premature luteinization (case 1, aged 35 years), and the other with the retrieval of high quality oocytes despite premature ovulation (case 2, aged 39 years).

Methods

Serum LH was 36 and 47 IU/L on cycle day?7 before antagonist administration, which was then brought to 6.94 and 3.92 IU/L by antagonist administration, and kept below these levels throughout the remaining stimulation in case 1 and 2 respectively. Serum progesterone was 1.42 and 5.5 ng/mL on the day of hCG respectively. Ten metaphase II (MII) oocytes were harvested wherein 3 grade A embryos were transferred in case 1, and seven good quality MII oocytes were retrieved wherein six embryos were cryopreserved in case 2.

Conclusions

More precise cut thresholds for both LH and progesterone are necessary for accurate prediction of the cycle outcomes.     

Follicular fluid concentrations of IGF-I, IGF-II, IGFBP-3, VEGF, AMH, and inhibin-B in women undergoing controlled ovarian hyperstimulation using GnRH agonist or GnRH antagonist

Objective

To compare follicular fluid concentrations of IGF-I, IGF-II, IGFBP-3, inhibin-B, VEGF, and AMH in women undergoing controlled ovarian hyperstimulation with a long-luteal GnRH agonist protocol or multiple-dose GnRH antagonist protocol.

Study design

A total of 80 cycles were included; long-luteal GnRH agonist group (n = 40) and multiple dose GnRH antagonist group (n = 40). All follicular fluid samples were obtained from mature follicles during oocyte retrieval. IGF-I and IGFBP-3 concentrations were measured by immunoradiometric assay. IGF-II, VEGF, AMH, and inhibin-B concentrations were measured by enzyme-linked immunosorbent assay.

Results

There were no significant differences in the concentrations of the studied follicular fluid markers, cycle parameters, and treatment outcomes between GnRH agonist and GnRH antagonist protocols.

Conclusions

The long-luteal GnRH agonist protocol and multiple-dose GnRH antagonist protocol seem to have similar effects on the follicular microenvironment in women undergoing controlled ovarian hyperstimulation.
