Nerve injury after laparoscopic surgery is presumably rare, with only scarce reports in the literature; however, the use of these techniques for new purposes presents the opportunity for novel complications. The authors report a case of subcostal nerve injury after an anterior laparoscopic approach to a posterior abdominal wall lipoma.<\/jats:p><jats:p>A 62-year-old woman presented with a left abdominal flank bulge (pseudohernia) that developed after laparoscopic posterior flank wall lipoma resection. Imaging demonstrated frank ballooning of the oblique muscles; denervation atrophy and thinning of the external oblique, internal oblique, and transverse abdominis muscles; and thinning of the rectus abdominis muscle. The patient underwent subcostal nerve repair and removal of a foreign plastic material from the laparoscopic procedure. At 8 months, she has regained substantial improvement in abdominal wall strength.<\/jats:p><jats:p>Although endoscopic procedures have resulted in significant reduction in morbidity, \u201cminimally invasive\u201d approaches should not be confused with \u201clow risk\u201d when approaching novel pathology. The subcostal nerve is at risk of injury in posterior abdominal wall surgery, whether laparoscopic or not. With the pseudohernia and abdominal bulge after this surgery, the cosmetic appeal of laparoscopic incisions was definitively undone. Selecting an approach based on the anatomy of adjacent structures may lead to a better functional result.<\/jats:p>","DOI":"10.3171\/2018.7.jns18532","type":"journal-article","created":{"date-parts":[[2019,2,27]],"date-time":"2019-02-27T00:14:41Z","timestamp":1551226481000},"page":"1855-1859","source":"Crossref","is-referenced-by-count":4,"title":["Subcostal nerve injury after laparoscopic lipoma surgery: an unusual culprit for an unusual complication"],"prefix":"10.3171","volume":"131","author":[{"given":"Hussam","family":"Abou-Al-Shaar","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah; and"},{"name":"Department of Neurosurgery, Hofstra Northwell School of Medicine, Manhasset, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark A.","family":"Mahan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"World Neurosurg","doi-asserted-by":"publisher","first-page":"669","DOI":"10.1016\/j.wneu.2017.05.055","article-title":"The subcostal nerve during lateral approaches to the lumbar spine: an anatomical study with relevance for injury avoidance and postoperative complications such as abdominal wall hernia","volume":"104","author":"Alonso F","year":"2017","unstructured":"Alonso F, Graham R, Rustagi T, Drazin D, Loukas M, Oskouian RJ, : The subcostal nerve during lateral approaches to the lumbar spine: an anatomical study with relevance for injury avoidance and postoperative complications such as abdominal wall hernia.
