    Does laparoscopic-guided transversus abdominis plane block have an effect on postoperative pain and recovery after sleeve gastrectomy?
    (Verduci Publisher, 2022) Okut, G.; Turgut, E.; Kaplan, K.; Bag, Y. M.; Akbas, S.; Sumer, F.; Kayaalp, C.
    - OBJECTIVE: Postoperative pain management is thought to have an effect on pa-tient comfort, morbidity, and mortality after bar-iatric surgery. Local anesthetic agents are fre-quently used for this purpose. Local anesthetics can be used in many different ways. In this study, we aimed to investigate the effect of transversus abdominis plane (TAP) block on postoperative pain by laparoscopic method.PATIENTS AND METHODS: A prospective randomized clinical trial was performed. While TAP block was applied to one group with bupiv-acaine, no action was taken for the other group. Postoperative analgesia was given to both pa-tient groups with the patient-controlled anal-gesia (PCA) device. Demographic, operational, and postoperative clinical and pain data of the patients were recorded. RESULTS: TAP block and non-TAP block groups consisted of 30 patients each. Visual analog scale (VAS) scores of the patients at 6, 12, and 24 hours were lower in the TAP group compared to the non -TAP group (p=0.015, 0.018, 0.04, respectively). Ac-cording to the PCA device data, the analgesic re-quirement was lower in the TAP group at 6, 12, and 24 hours (p <0.001). Rescue analgesia was re-quired more in the non-TAP group (p=0.04). There was no statistically significant difference between the two groups in terms of gas discharge time (p=0.102), stool discharge occurred earlier in the TAP group (p=0.02). Oral intake times (p=0.554) and length of stay hospital (p=0.551) were similar.CONCLUSIONS: Laparoscopic TAP block us-ing bupivacaine can be safely administered in morbidly obese patients and reduces postoper-ative analgesic requirements. Thus, side effects that may develop secondary to the use of anal-gesics are avoided.

    The magnetic resonance imaging assessment of optic nerve sheath diameter in pediatric acute liver failure patients
    (Verduci Publisher, 2022) Dogan, G. M.; Sigirci, A.; Okut, G.; Cicek, E.; Dogan, S. M.; Yilmaz, S.; Arslan, A. K.
    OBJECTIVE: To evaluate the di-agnostic value of optic nerve sheath diameter (ONSD) using brain MRI in the pretransplantation period in the pediatric acute liver failure patients, and correlate the ONSD with clinical grade of hepatic encephalopathy (HE) and MRI findings. PATIENTS AND METHODS: Forty acute liver failure patients and 40 control group patients were retrospectively analyzed. The high signal intensities in T2W (T2-weighted image), FLAIR (Fluid Attenuated Inversion Recovery) and DWI (diffusion-weighted imaging) sequences were evaluated and ONSD were measured. The patients were grouped first into 5 according to their West Haven score, and HE grade 0 and grade 1 were accepted as low grade HE, HE grade 2, 3 and 4 were accepted as high grade HE. The patients were grouped to 2 according to the MRI findings as low grade and high grade MRI group. RESULTS: The mean value of ONSD was 6.0 +/- 1.80 and 4.94 +/- 1.27 in all the patients and in the control group, respectively. There was statistically significant difference between both the ONSD and the low grade-high grade HE groups (p=0.01), and between the ONSD and the low grade-high grade MRI groups (p<0.001). CONCLUSIONS: Although high ONSD values do not make the diagnosis of cerebral edema, it may cause suspicion in the early period. MRI can be helpful in the diagnoses of increased intracranial pressure like ultrasound. Our study is the first study to compare ONSD and MRI findings in addition to HE grades. The widespread use of MRI in children in recent years may help determine the normal range of ONSD values.

    Should Interventional Radiology or Open Surgery Be the First Choice for the Management of Ureteric Stenosis After Transplantation? Dual-Center Study
    (Elsevier Science Inc, 2017) Simsek, C.; Dogan, S. M.; Piskin, T.; Okut, G.; Cayhan, K.; Aykas, A.; Tatar, E.
    Background. Ureteric stenosis (US) is the most common urologic complication after kidney transplantation. In this dual-center retrospective study we compared the efficacy and safety of open surgery versus interventional radiology for the management of US. Methods. From 2009 to January 2016, US was treated by surgical revision in 22 (7.8%) out of 281 recipients at one center (group 1) and managed by percutaneous nephrostomy with antegrade nephroureteral stenting (PNAS) in 22 (14.2%) out of 155 recipients at the other center (group 2). Results. Three patients in group 1 required reintervention and again were treated with open surgery. With a mean follow-up of 42.1 +/- 38.7 months, graft function improved in all but one patients (95%). Three patients in group 2 were admitted with relapse of US not amenable to 2nd PNAS, and 2 of them were managed with surgery. These 3 and 2 other cases with improved graft function after PNAS lost their grafts and returned to hemodialysis. The remaining 17 patients (77%) still have functioning grafts. There was no statistically significant difference between the efficacy of PNAS and open surgery for the management of post-transplantation US. However; a benefit in favor of open surgery existed for type 2 urinary tract obstruction in terms of decreased reintervention rate and much better protection of the graft function and survival. Conclusions. Both interventional radiology and open surgery have acceptable efficacy rates in the management of ureteric complications after renal transplantation. Open surgery is a better treatment option for type 2 obstruction.
