Most of the reported vascular injuries in laparoscopy occur during trocar or Veress needle insertions https://www.selleckchem.com/products/EX-527.html [7]. For patients over the age of 65, population-based studies have even suggested a lower mortality with LA [8]. As laparoscopy continues to evolve, it is essential that surgeons report unusual complications in an effort to raise awareness and guide management of any iatrogenic injury incurred during minimally-invasive procedures. We report the case of a patient who sustained a major

non-trocar related retroperitoneal vascular injury during a routine LA. Case Report The patient is a 38 year old obese male, otherwise healthy, who presented with a 24 hour history of right lower quadrant pain and anorexia. His laboratory workup LCZ696 order revealed a leukocytosis with eighty percent neutrophilia. On abdominal examination, the patient had localized tenderness lateral to McBurney’s point with a positive psoas sign. A computed tomography scan confirmed the presence of a 16 mm enlarged appendix with signs of surrounding

inflammation [Figure 1]. The patient was promptly taken to the operating room for a LA. A 12 mm periumbilical trocar was placed under direct vision followed by placement of a 5 mm suprapubic port and a 5 mm left lower quadrant port. The peritoneal cavity was insufflated with carbon dioxide to a pressure of 15 mm Hg. Upon exploration of the abdomen, the appendix was confirmed to be retrocolic ASK1 in location, significantly inflamed, and adherent to the posterolateral abdominal wall. As the appendix was bluntly mobilized and freed from its posterolateral attachment, a sudden small amount of venous bleeding was noted to originate behind the cecum. After the OSI-027 appendectomy was completed in the usual manner using two endo-GIA™ stapler loads, we focused our attention on identifying and controlling the bleeding. Upon close inspection, both staple lines appeared intact, and the bleeding was confirmed to be retroperitoneal in location, and more significant in severity than initially suspected. Repetitive attempts to expose and identify the bleeding vessel

laparoscopically failed. At this point, we proceeded with a transverse Rocky-Davis muscle-splitting open incision. A Bookwalter retractor was placed, and exposure was ultimately achieved despite the patient’s large body habitus (body mass index = 42 kg/m2). The bleeding vessel was identified as the right gonadal vein which had apparently avulsed upon mobilization of the retrocolic appendix. The testicular vein was suture-ligated with 3-0 vicryl sutures with cessation of the bleeding. Care was taken to avoid injuring the ureter. By the end of the procedure, the patient had lost 1200 ml of blood and had received two units of packed red blood cells. The patient did well after the procedure and was discharged home on the second postoperative day in stable condition without any major sequelae.
