Its manifestation as acute bowel obstruction without hemorrhage is exceedingly uncommon, especially in children, posing a diagnostic dilemma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case description<\/jats:title>\n                    <jats:p>A previously healthy 9-year-old boy presented with acute abdominal pain and vomiting. Contrast-enhanced computed tomography revealed a homogeneously enhancing lesion with persistent enhancement on portal venous phase in the left pelvic small bowel, raising suspicion of a vascular malformation. Diagnostic laparoscopy was subsequently performed, identifying a 5\u2005cm segment of small intestine with its serosal surface densely covered by tortuous vessels. Laparoscopic segmental resection with primary hand-sewn end-to-end anastomosis was performed. Immunohistochemistry revealed CD31 and CD34 positivity in lesional endothelial cells and GLUT-1 negativity, excluding infantile hemangioma. This immunoprofile, together with the characteristic morphology, supported the diagnosis of a venous malformation according to the International Society for the Study of Vascular Anomalies (ISSVA) classification. The patient recovered uneventfully and remained asymptomatic with no evidence of residual lesion or symptom relapse during a 6-month follow-up period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This case suggests that a small intestinal venous malformation can rarely present as acute obstruction in the absence of bleeding. Contrast-enhanced CT with persistent enhancement pattern is a useful preoperative indicator, and laparoscopy appears to be a feasible approach for both diagnosis and minimally invasive resection. This integrated diagnostic and therapeutic strategy should be considered in select children with small bowel obstruction of uncertain etiology.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fped.2026.1866822","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T06:02:36Z","timestamp":1785304956000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Laparoscopic resection of a small intestinal venous malformation presenting as acute bowel obstruction without hemorrhage in a child: a case report"],"prefix":"10.3389","volume":"14","author":[{"given":"Wei","family":"Peng","sequence":"first","affiliation":[{"name":"Department of Pediatric Surgery, The First Affiliated Hospital of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuyang","family":"Zheng","sequence":"additional","affiliation":[{"name":"The First Clinical Medical College of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhancheng","family":"Li","sequence":"additional","affiliation":[{"name":"The First Clinical Medical College of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiqi","family":"Zhao","sequence":"additional","affiliation":[{"name":"The First Clinical Medical College of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haijin","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, The First Affiliated Hospital of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, The First Affiliated Hospital of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]},{"name":"National Clinical Key Specialty (Pediatrics), The First Affiliated Hospital of Gannan Medical University","place":["Ganzhou, Jiangxi, China"]},{"name":"Jiangxi Provincial Clinical Research Center for Vascular Anomalies, The First Affiliated Hospital of GanNan Medical University","place":["Ganzhou, Jiangxi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2358","DOI":"10.3390\/ijms23042358","article-title":"Issva classification of vascular anomalies and molecular biology","volume":"23","author":"Kunimoto","year":"2022","journal-title":"Int J Mol Sci"},{"key":"B2","doi-asserted-by":"publisher","first-page":"e203","DOI":"10.1542\/peds.2014-3673","article-title":"Vascular anomalies classification: recommendations from the international society for the study of vascular anomalies","volume":"136","author":"Wassef","year":"2015","journal-title":"Pediatrics"},{"key":"B3","first-page":"939","article-title":"Solitary cavernous hemangioma of small intestine.
