RESUMO
INTRODUCTION: Spleno-sigmoid knotting is the twisting of the spleen around the sigmoid colon, causing obstruction of the sigmoid colon. It is an uncommon cause of intestinal obstruction. To our knowledge, there has been no previous case report of spleno-sigmoid knotting before our case. CASE REPORT: Here, we present the case of an 18-year-old female patient who visited the surgical emergency outpatient department with diffuse and progressive abdominal pain lasting for one and a half days. She also experienced obstipation and frequent episodes of vomiting of ingested matter. Upon initial evaluation, she exhibited tachycardia and tachypnea, and her abdomen was grossly distended with diffuse direct and rebound tenderness. Further investigation revealed significant leukocytosis with neutrophil predominance. Emergency laparotomy was performed with a possible diagnosis of generalized peritonitis secondary to gangrenous sigmoid volvulus, which revealed gangrenous spleno-sigmoid knotting. DISCUSSION: Various types of intestinal knots have been reported, with ileo-sigmoid knots being the most common and ileo-ileal knots being the rarest. Wandering spleen is a rare congenital anomaly with a variable clinical presentation ranging from asymptomatic to mild abdominal pain or acute abdomen due to torsion or acute pancreatitis. It can also cause intestinal obstruction, which may be the initial presentation. CONCLUSION: In patients presenting with acute abdominal pain and features of bowel obstruction, the possibility of spleno-sigmoid knotting should be considered, and early intervention should be instituted to prevent gangrenous progression and sepsis.
