Background: Roux-en-Y gastric bypass (RYGB) is a surgery with low rate complications. However, it is not exempt from them, and 1-6% suffer complications such as postoperative bleeding. Many intraoperative techniques have been evaluated to reduce postoperative bleeding, like the oversewing or reinforcement of the staple line. This study aims to evaluate the rate of postoperative bleeding in the oversewing of the staple line of the gastric remnant group versus the stapling only group.
Methods: This is a 2-center, case-control study. We randomly selected two groups who underwent RYGB or OAGB: group A (n = 225) with oversewing from 2019 to 2020 and group B (n = 225) with stapling only between the period of 2017-2018; both groups with similar demographic characteristics.
Results: The overall mean age was 37.39 ± 9.6 years and mean BMI was 41.59 ± 8.6 kg/m2; the postoperative bleeding rate was significantly lower (p < 0,05) in patients with oversewing of the staple line of the gastric remnant. Operative time was shorter for the stapling only group and the difference between the mean operative time was 10.6 min.
Conclusions: Oversewing the staple line of the gastric remnant significantly reduces the incidence of postoperative bleeding regardless of BMI. Being a cost-effective technique compared to others available despite the increase in operating time.

Multifaceted approach to evacuating multi-level premacular hemorrhage in a case of suspected Valsalva retinopathy - a case report.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.

Purpose: Bone cement-reinforced fenestrated pedicle screws (FPSs) have been widely used in the internal fixation and repair of the spine with osteoporosis in recent years and show significant improvement in fixation strength and stability. However, compared with conventional reinforcement methods, the advantages of bone cement-reinforced FPSs remain undetermined. This article compares the effects of fenestrated and conventional pedicle screws (CPSs) combined with bone cement in the treatment of osteoporosis.

Introduction: Acute severe ulcerative colitis (ASUC) is a critical manifestation of ulcerative colitis (UC), often necessitating colectomy when medical management fails. Despite advancements in therapeutic interventions such as corticosteroids, biologics, and JAK inhibitors, a significant proportion of patients require surgery, with colectomy rates ranging from 10% to 15%.
Areas Covered: This paper reviews the factors influencing the timing and necessity of colectomy in ASUC management, emphasizing the importance of multidisciplinary decision-making involving gastroenterologists and surgeons.
Purpose: Proliferative vitreoretinopathy (PVR) is the leading cause of surgical failure following rhegmatogenous retinal detachment (RRD). In this study, we aimed to explore ocular and systemic risk factors for PVR due to RRD in a large patient database.
Methods: Patients who have a diagnosis of RRD and PVR, and who have been seen in the last seven years prior to analysis (January 2015-February 2023) were identified in the Vestrum Health database.
Ureteral access sheath or percutaneous nephrostomy during flexible ureteroscopy: which is better?

Studies in literature discussed the drawbacks of the ureteral access sheath use in flexible ureteroscopy and in the same time mentioned the benefits of ureteral access sheath in decreasing the incidence of urosepsis and better stone free rate. In the current study we aim to compare between percutaneous nephrostomy tube (PCN) insertion before flexible ureteroscopy and conventional ureteral access sheath (UAS) flexible ureteroscopy in terms of safety, efficacy and perioperative outcomes. In all, 100 Patients aged 20 to 67 years with upper ureteric stones and mild hydronephrosis or renal pelvic stones less than 20 mm with mild hydronephrosis were randomized into 2 groups; patients undergoing PCN insertion before flexible ureteroscopy, and patients undergoing the conventional UAS flexible ureteroscopy.
