To insert the spinal catheter into the subarachnoid lumbar space, LPS is usually performed with the patient in the lateral decubitus position. However, laparotomy around the periumbilical region, especially in obese patients in the lateral decubitus position, can be quite difficult. Thus, the authors added a simple modification to the laparotomy for LPS, altering the laparotomy site to the lateral side of the patient\u2019s trunk. The aim of this study was to analyze this method in terms of technical features and outcomes.<\/jats:p><\/jats:sec>METHODS<\/jats:title>Two LPS procedures were compared: routine periumbilical anterior abdominal laparotomy and our modified method using lateral abdominal laparotomy. The first 11 consecutive cases underwent routine anterior abdominal laparotomy with position changes or tilting of the operative bed, whereas the next 17 consecutive cases underwent lateral abdominal laparotomy not requiring position changes.<\/jats:p><\/jats:sec>RESULTS<\/jats:title>In the anterior abdominal laparotomy group, the mean operative time was 72.36 \u00b1 24.63 minutes. One patient had a spinal tube tear that required revision of the LPS 2 years postoperatively. In the lateral abdominal laparotomy group, the mean operative time was 38.82 \u00b1 13.87 minutes. One patient experienced a postoperative headache and exhibited a thin, chronic subdural hematoma on imaging studies, which disappeared after adjustment of the valve pressure.<\/jats:p><\/jats:sec>CONCLUSIONS<\/jats:title>In the current series, the operative duration was shorter in the lateral abdominal group compared with the anterior abdominal group, with no differences in complication rates. Lateral abdominal laparotomy simplifies LPS.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2019.10.spine19957","type":"journal-article","created":{"date-parts":[[2019,12,20]],"date-time":"2019-12-20T22:45:17Z","timestamp":1576881917000},"page":"548-553","source":"Crossref","is-referenced-by-count":9,"title":["Lumboperitoneal shunt surgery via lateral abdominal laparotomy"],"prefix":"10.3171","volume":"32","author":[{"given":"Yukihiro","family":"Goto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideki","family":"Oka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sho","family":"Nishii","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasufumi","family":"Takagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeomi","family":"Yokoya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiko","family":"Hino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"No Shinkei Geka","first-page":"511","article-title":"[Laparoscopy-assisted ventriculoperitoneal and lumboperitoneal shunt surgery","volume":"40","author":"Aoki T","year":"2012","unstructured":"Aoki T, Ayuzawa S, Matsuo R, Hosoo H, Tanno S, Miki S, : [Laparoscopy-assisted ventriculoperitoneal and lumboperitoneal shunt surgery.] No Shinkei Geka 40:511\u2013517, 2012 (Japanese)22647510"},{"key":"b2","series-title":"Rev Neurol","first-page":"300","article-title":"[Lumboperitoneal shunt in an outpatient setting for the treatment of chronic hydrocephalus in adults.
