Use of microcatheter for intraabdominal survey

Abstract

BackgroundLaparoscopy is the most common procedure for minimally invasive intraabdominal surveys. Patients with pulmonary hypertension (PHTN) may need an alternate approach because the systemic absorption of carbon dioxide may lead to hypercapnia, acidemia, and increases in systemic and pulmonary pressures. We report a case of intraabdominal survey using a microcatheter trocar (Check-Flo Introducer) in a patient with a large adnexal mass and PHTN. CaseAn adolescent girl with severe PHTN and multiple cardiac anomalies presented with oligomenorrhea. During the course of workup, an ultrasound revealed an 8-cm simple cyst in the right adnexa, which required removal. The decision was made to proceed with cystectomy. The patient was not a candidate for laparoscopy, and an alternative method was used. The Check-Flo Introducer, a microcatheter trocar; crystalloid fluid infusion; and a 3-mm laparoscopic camera were used to survey the abdominal cavity, revealing a 10-cm simple paratubal cyst that could be safely drained and removed via a minilaparotomy incision. ConclusionThe microcatheter trocar is a useful and novel alternative in patients who cannot tolerate increases in intraabdominal pressure.
