Intussusception is a medical condition characterized by invagination of the intestinal segment, causing obstruction and leading to potential complications such as ischemia, necrosis and perforation. While paediatric intussusception is well documented with a peak in ages between 4 and 36 months, adult intussusception is a rare condition usually involving a lead point. In this article, we present an uncommon case of an adult male with worsening of his long-standing lower abdominal pain for the last 2 months. Radiological test reports revealed target-like lesions demonstrating two intestinal intussusceptions, for which he underwent a small bowel anastomosis, exploratory laprotomy and resection. On receiving the histopathology report, hamartomatous polyps with features favouring Peutz-Jegher's syndrome were identified as a possible lead point.

Unusual manifestations of Peutz-Jegher's syndrome in children.

J Indian Assoc Pediatr Surg

March 2022

Department of Gastroenterology, PGIMER, Chandigarh, India.

PeutzJegher's syndrome (PJS) is a rare, autosomal dominant disease, characterized by gastrointestinal (GI) polyps and perioral hyperpigmentation along with the increased risk of certain malignancies. In children, the most common presentation is recurrent intussusception due to polyps. These polyps can involve any part of the GI tract and can present with a variety of clinical presentations.

Pancreatic Cancer Screening.

Curr Treat Options Gastroenterol

December 2017

Division of Gastroenterology, Department of Medicine, Washington University School of Medicine, 660 South Euclid Avenue Campus, Box 8124, St. Louis, MO, 63110-1093, USA.

Purpose Of Review: This review describes the rationale for pancreatic cancer screening, outlines groups that are at elevated risk for pancreatic cancer, and summarizes the relative risk in each setting. We also review the methods available for performing pancreatic cancer screening and the recommended screening intervals.

Recent Findings: Several genetic mutations have been identified that increase the risk for pancreatic cancer.

Peutz-Jegher's syndrome (PJS) involves multiple organ systems and the development of hamartomatous, metaplastic, or neoplastic lesions of different cell lineages. Among them, glandular lesions are the most common, but their properties are obscure. We report here a 53-year-old woman with PJS who developed multiple hamartomatous polyps in the jejunum and mucinous glandular lesions in multiple organ systems: glandular metaplasia in the urinary bladder; lobular endocervical glandular hyperplasia in the uterine cervix; mucinous metaplasia in the right fallopian tube; mucinous adenoma in the left ovary.

Objective: Molecular pathogenesis of gastrointestinal polyposis in Peutz-Jegher's syndrome (PJS) has been linked to the loss-of-function mutation of LKB1. Recent functional genetic studies have pointed out that LKB1 plays a physiological role in controlling the Wnt-signaling pathway and activation of the pathway as a consequence of LKB1 haploinsufficiency might be responsible for the development of harmatomatous polyps. This study aimed to look for immunohistochemical evidence of Wnt-signaling activation in PJS polyps.
