Aim: To assess the feasibility and safety of a novel enteroscope, negative-pressure suction endoscope in examining the small intestine of a porcine model.
Methods: experiments in small intestinal loops from 20 pigs and experiments in 20 living pigs were conducted.
Results: In experiments, a negative pressure of > 0.06 MPa was necessary for optimal visualization of the intestine, and this pressure did not cause gross or histological damage to the mucosa. For satisfactory examination of the small intestine , higher negative pressure (> 1.00 MPa) was required. Despite this higher pressure, the small intestine did not show any gross or microscopic damage in the suctioned areas. The average time of examination in the living animals was 60 ± 7.67 min. The animals did not experience any apparent ill effects from the procedure.
Conclusion: Small intestine endoscope was safely performed within a reasonable time period and enabled complete visualization of the intestine in most cases.

Intussusception in adults is rare and poses a diagnostic challenge, often due to neoplastic causes. Metastatic melanoma is known to spread to the gastrointestinal tract, especially the small intestine. We report the case of a patient with obstructive symptoms and a history of metastatic melanoma.

This condition results in hypoalbuminemia, hypogammaglobulinemia, and lymphopenia due to the abnormal leakage of lymphatic fluid into the gastrointestinal tract. As there are no specific serological or radiological tests available, the gold standard for diagnosing intestinal lymphangiectasia is endoscopic examination with histopathological examination of intestinal biopsy specimens.

Lymphatic Malformations (LMs) are benign congenital malformations of the lymphatic system that commonly involve the abdomen in children (mesentery of the small intestine and omentum). The management of these malformations is not unique. 7 children with different ages (range: newborn to 14 years), diagnosis was incidental in some cases, while in others for abdominal pain.

The broad ligament, a double-layered peritoneum attaching the lateral uterus to the pelvic sidewall, plays a vital role in pelvic anatomy. Small bowel herniation through a defect in the broad ligament, known as broad ligament herniation, involving protrusion of viscera through defects in this ligament, is rare but can lead to severe complications. This systematic review aims to evaluate the presentation, diagnosis, management, and factors associated with broad ligament herniation.

Tropical peas can be used as both animal feed and human food but the nutritional quality of their proteins for humans is currently poorly documented. Here, 3 varieties of tropical peas were studied at two stages of seed maturity (green or dry): Cajanus Cajan (CC), Vigna Unguiculata (VU) and Lablab Purpureus (LP). Pea seeds were prepared traditionally (soaking and cooking).
