Mechanisms and Therapeutic Approaches for Peritoneal Adhesions: A Comprehensive Review.

Peritoneal adhesions are responsible for several and sometimes severe clinical phenotypes remaining a major problem for many patients today. Adhesions are formed within the peritoneal cavity as a result of surgery, inflammation, or injury and can cause a range of clinical symptoms, including abdominal pain, small bowel obstruction, infertility, and other complications. The incidence of peritoneal adhesions remains high as it is estimated that more than 50% of patients who undergo abdominal surgery will develop adhesions. Although advancements in surgical techniques and perioperative management have been developed, the risk of adhesion formation cannot be eliminated, and thus, the development of effective prevention strategies and treatments remains a priority in the field of surgery. In this review, we summarize the cellular and molecular mechanisms involved in the peritoneal adhesions, but also the experimental therapy approaches that have been investigated toward a solution to their possible clinical phenotypes.

Bowel perforation by lumbar-peritoneal (LP) shunt: A rare complication of neurosurgery.

INTRODUCTION: Lumbar-peritoneal (LP) and ventriculo-peritoneal (VP) shunt placement is the treatment of choice for diversion of cerebrospinal fluid (CSF) from the subarachnoid space into the peritoneal cavity. This invasive procedure has been associated with several complications, most commonly infection and obstruction. Perforation of the bowel is an extremely rare complication. CASE PRESENTATION: We report a case of a 72 old female patient with LP shunt for raised intracranial pressure, who presented with LP shunt catheter protruding from anus. This was due to bowel perforation in the recto-sigmoid junction by the distal tip of lumbar-peritoneal shunt. She was surgically treated with removal of the distal part of the shunt, external drainage of the proximal part and primary closure of the perforation. DISCUSSION: The mortality after perforation is relatively high, approaching 15-18%, and it is further increased when infection is present up to 22% with central nervous system (CNS) infection such as meningitis, encephalitis, or brain abscesses (Vinchon, 2006) and 33% with intra-abdominal infection. CONCLUSION: Clinical suspicion of abdominal complications by the LP should be raised when patient with hydrocephalus develops acute abdominal symptoms or infection with unusual positive CSF cultures.
