Article Abstract
Background: Delayed gastric emptying (DGE) is a widespread complication after left-sided hepatectomy (LSH). The usage of omental flap (OF) in patients after LSH is thought to reduce the incidence of DGE. Therefore, a meta-analysis was performed in order these findings to be explored.
Methods: Pubmed, Embase and Cochrane Central were searched for studies comparing usage of omental flap to no-OF in patients after LSH. The primary outcome was DGE. Statistical analysis was performed using Review Manager 5.4 (Cochrane Collaboration). Heterogeneity was assessed using I statistics. Odds ratios (OR) were computed for binary endpoints using a random-effects model.
Results: 358 patients were included from 7 studies, of which 2 were randomized controlled trials (RCTs). Male sex was predominant (68 %). OF was used for prevention of DGE in 155 cases. In 3 of the studies the greater omentum was divided for the preparation of the flap. DGE (OR 0.10; 95 % CI 0.04-0.23; p < 0.00001; I = 0 %) and overall morbidity (OR 0.31; 95 % CI 0.13-0.74; p = 0.008; I = 0 %) were significantly reduced in the OF group, compared to the no-OF group.
Discussion: Utilization of omental flap in patients with left-sided hepatectomy significantly reduces the incidence of DGE and overall morbidity, compared to the no-omental flap procedure.

Management of cocaine-induced midline lesion (CIMDL) extended to skull base: a case report and systematic review.

Purpose: Cocaine-induced midline destructive lesions (CIMDL) represent a rare but severe consequence of intranasal cocaine abuse, occasionally progressing to skull base involvement with life-threatening complications. The aim of this manuscript is to describe an exceptional case of CIMDL with clival destruction and brainstem exposure, and to review current management strategies based on a systematic literature review.
Methods: We report a unique case of a 39-year-old woman with CIMDL extending to the clivus, resulting in encephalocele with basilar artery and brainstem exposure.

Mycotic pseudoaneurysms are rare infectious complications that may involve the aorta, peripheral arteries, cerebral arteries, or visceral arteries. We present a unique case of thoracoabdominal mycotic pseudoaneurysm secondary to hematogenous spread of from spinal osteomyelitis. The infections started with bacterial translocation to the calcified ostial plaque around the celiac origin, which then degenerated into a rapidly growing pseudoaneurysm.

Background: The bladder represents one of the genitourinary organs most vulnerable to iatrogenic injuries. Ideal repair can be challenging and may require augmentation to fully preserve bladder structure and function. The omentum has been employed as a flap or graft to close bladder defects.

Perineal wound complications and pelvic fluid collections or abscesses following proctectomy for Crohn's disease are a common cause of morbidity and might be mitigated by filling the pelvis and occluding the pelvic inlet with a flap. Alternative flap options can be considered when inadequate omentum is available and when avoiding myofasciocutaneous flaps. A retrospective review of our Crohn's proctectomy database was conducted to identify patients who underwent a non-omental or non-myofasciocutaneous local pedicle flap to their pelvis or pelvic exclusion using biological material during surgery.
