Aim: Laparoscopic ventral mesh rectopexy (VMR) is a surgical option for internal and external rectal prolapse with low perioperative morbidity and low recurrence rates. Use of synthetic mesh in the pelvis may be associated with complications such as fistulation, erosion and dyspareunia. Biological meshes may avoid these complications, but the long-term outcome is uncertain. Debate continues as to which type of mesh is optimal for laparoscopic VMR.
Method: A literature search was performed of electronic databases including MEDLINE, Embase and Scopus (2000-12). Studies describing outcomes relating to the mesh were included for review. Only English language studies were included.
Results: Thirteen observational studies reported the outcome of 866 patients following laparoscopic VMR. Eleven reported the outcome using synthetic mesh with a median follow-up ranging from 7 to 74 months. Two studies reported the outcome with biological mesh with a median follow-up of 12 months. Pooled analysis of the studies demonstrated that 767 patients had a repair with synthetic mesh and 99 with a biological implant. There was no difference in recurrence (3.7 vs 4.0%, P = 0.78) or mesh complications (0.7 vs 0%, P = 1.0%) between synthetic and biological mesh repair.
Conclusion: Biological meshes appear to be as effective as synthetic meshes in the short term for laparoscopic VMR. Mesh complication rates are low in both groups. Long-term follow-up is required to ascertain if these findings persist.

Purpose Of Review: Whether low birth weight (LBW) and preterm delivery (PD) are associated with the risk of developing celiac disease (CD) in children remains unclear. This systematic review and meta-analysis aimed to evaluate the association between LBW and PD with CD development in children.
Recent Findings: We searched PubMed, Embase, Scopus, Web of Science, and Google Scholar databases based on the Mesh terms to find observational studies that investigated the association of LBW and PD with CD development in children up to July 18, 2024.

Aim: Ventral mesh rectopexy (VMR) is an established surgical treatment for rectal prolapse and outlet obstruction. In contrast to continental Europe, in the UK and US the use of synthetic mesh has been abandoned in favour of biologic mesh, due to concerns regarding mesh related morbidity. The current study investigated if either material is superior, in terms of clinical recurrence and mesh related complications.

Ectopic varices can result from portal vein stenosis following pancreaticoduodenectomy with concomitant portal vein resection reconstruction, and they can cause gastrointestinal bleeding. Although they can sometimes be fatal, various treatments have been reported. This report describes a case in which a percutaneous transhepatic approach was used to simultaneously perform variceal embolization and portal vein stenting in which a favorable outcome was achieved.

Ethnopharmacological Relevance: Cuttlebone (CB), also known as SEPIAE ENDOCONCHA, is the inner shell of cuttlefish and has been employed in traditional medicine in numerous countries since antiquity. Despite its significant medicinal value, CB is often underestimated and discarded on the beach as debris in some countries, which considerably impacts the environment and economy.
The Aim Of The Review: This study aims to elucidate the value of CB, particularly in the context of its medicinal properties, to promote its rational utilization.
