Emergency laparoscopic cholecystectomy for intraabdominal hemorrhage in a patient with a left ventricular assist device: a case report
Surgical Case Reports volume 5, Article number: 196 (2019)
Continuous-flow left ventricular assist devices (LVADs), called “second generation LVADs,” have significantly improved the survival and quality of life outcomes. Accordingly, non-cardiac surgery in a patient with LVADs has required for conditions not directly related to their LVADs. And the management of bleeding in non-cardiac site remains one of long-term critical topics. Laparoscopic approach is useful in a patient with LVADs; however, there have been only few clinical reports. This report describes the first case of laparoscopic cholecystectomy (LC) for intraabdominal hemorrhage from the gallbladder serosa in a patient with LVADs.
A 56-year-old man with an LVAD had undergone LVAD (Jarvik 2000™; Jarvik Heart, Inc., New York, NY, USA) implantation at 53 years of age. He was in shock, and contrast-enhanced computed tomography revealed abdominal hemorrhage from the gallbladder serosa. Emergency laparoscopic cholecystectomy was performed. We could avoid injury of the LVADs driveline, which was located across the upper abdominal midline, near the right hypochondriac region, by laparoscopic approach. LVADs (Jarvik 2000) did not disturb the operating field because of its smaller size. There were no intra- and postoperative complications.
Laparoscopic approach is useful and safe in a patient with LVADs for abdominal surgery. We could perform LC for intraabdominal hemorrhage from gallbladder serosa safety.
Continuous-flow left ventricular assist devices (LVADs), called “second generation LVADs,” have significantly improved the survival and quality of life outcomes . However, they have been associated with the development of non-cardiac complications over time . In abdominal surgery, it is very important to avoid injury of the LVAD driveline, which connects the main body with the controller running under the abdominal skin. Thus, laparoscopic approach is useful in these patients; however, there have been only few clinical reports. We herein report a first case of emergency laparoscopic cholecystectomy (LC) for intraabdominal hemorrhage from the gallbladder serosa in a patient with LVADs (Jarvik 2000™; Jarvik Heart, Inc., New York, NY, USA). Jarvik 2000 is a second-generation LVAD that features a miniaturized intraventricular pump (Fig. 1a).
A 56-year-old man was admitted to our hospital due to right heart failure and epistaxis that could not be controlled by pressure hemostasis. He had undergone LVAD (Jarvik 2000) implantation at 53 years of age due to severe heart failure after cardiovascular surgery (mitral valve replacement due to mitral regurgitation after mitral valve plasty and tricuspid annuloplasty for dilated cardiomyopathy). At the time of admission, he was on anticoagulation therapy with only oral warfarin that had maintained the prothrombin time-international normalized ratio (PT-INR) between 2.5 and 3.5. He had undergone mechanical ventilation therapy for heart failure and had a nasogastric tube inserted. Warfarin was administered through the tube. On day 4 after admission, the patient developed epistaxis. External carotid artery ligature and transcatheter coil embolization were performed for hemostasis. At that time, warfarin was discontinued and neutralized by menatetrenone (vitamin K). After the hemostatic treatments, warfarin was re-started with heparinization. The patient was weaned off mechanical ventilation on day 11 after admission. On day 15 after admission, he developed hypotension, abdominal distension, and mild abdominal pain. Blood tests revealed aggravating anemia; the serum hemoglobin dropped from 10.5 to 8.3 g/dL in 1 day. Contrast-enhanced computed tomography revealed abdominal hemorrhage. Signs of extravasation at the gallbladder wall and a gallstone were seen, but there were no signs of intra-gallbladder hemorrhage or acute cholecystitis (Fig. 1b). Abdominal X-rays were performed to confirm the LVAD driveline location; it was located across the upper abdominal midline, near the right hypochondriac region (Fig. 1c). At that time, the PT-INR and activated partial thromboplastin time were 1.36 and 50.2 s, respectively. We planned to perform emergency laparoscopic cholecystectomy; however, we had to consider the possibility of conversion to open surgery in case of insufficient operating space due to the hemorrhage and LVAD. Therefore, we prepared for laparotomy using X-ray fluoroscopy. We did not use menatetrenone or protamine sulfate for neutralization preoperatively. Before the start of the surgery, we made markings on the skin along the driveline by palpation to avoid its injury at trocar insertion. After the induction of general anesthesia with an arterial pressure line and a central venous catheter, the first trocar for the endoscope was inserted using the open approach (20-mm horizontal incision at the lower edge of the umbilicus). Pneumoperitoneum was created at 10 mmHg, and a 0° endoscope was inserted. On intraabdominal observation, abundant hemorrhagic ascites (a total of about 3000 ml) was seen in the abdominal cavity (Fig. 2A). The other ports were inserted as presented in Fig. 3, with the epigastric port inserted carefully while watching from the intraperitoneal side (Fig. 2B). As noted on the preoperative images, the bleeding point was at the gallbladder wall serosa (Fig. 2C). We were able to stop the bleeding by coagulation. The gallbladder wall had mild inflammatory changes, but there were no adhesions around the gallbladder. There was no finding of a perforation or bile leakage. Although the tissue was fragile and friable, we could perform standard LC (Fig. 2D). During the surgery, the main body and the driveline of the LVAD did not obstruct the operating field. The cystic duct and artery were clipped with a 10-mm clip applicator (Fig. 2E). After exploring the whole abdominal cavity, we confirmed no other bleeding points and no injury to other organs. We placed a drain in the subhepatic space and ended the operation without intraoperative complications (operation time, 1 h 59 min; intraoperative bleeding, 240 ml). The postoperative course was uneventful, and the drain was removed on postoperative day 2. On the same day, warfarin and heparin administration was re-started. The perioperative anticoagulation management and the trend of PT-INR and APTT (seconds) are presented in Fig. 4. After heart failure treatment, the patient was discharged home on postoperative day 30. No changes were made to the anti-coagulation management. At discharge, the dose of warfarin was 1.5 mg/day and PT-INR was 2.59. The pathological findings were gallbladder hemorrhage and chronic cholecystitis with a stone. The main area of hemorrhage was in the subserous tissue.
This case further supports the usefulness of laparoscopic approach for avoiding driveline injury in patients with LVADs. There are currently three case reports [3,4,5] and three case series including four to six cases [6,7,8] (Table 1) on laparoscopic cholecystectomy (LC) in patients with an LVAD. There were no cases of conversion to open surgery or critical intraoperative complications. Postoperative complications were reported in two patients who had acute kidney dysfunction and abdominal wall hematoma. All cases were reported on patients with a second- or third-generation LVAD. There are only two case reports of emergency LC, including our case. Naito et al. reported on emergency LC in a patient with an LVAD , but the type was DuraHeartTM (Termo Heart, Inc., AnnArbor, MI, USA). Compared with our case, a protruding main body and driveline of the LVAD and mild to severe adhesions to them were observed. We thus speculate that, almost certainly, laparoscopic surgery is easier to perform in patients with Jarvik 2000 than in those with other types of LVADs because of its smaller size.
Furthermore, the diagnosis in our case was hemorrhage and the bleeding point was the gallbladder serosa without perforation, severe cholecystitis. There was no traumatic episode; he had been in bed for treatment of heart failure and uncontrollable epistaxis. This finding is extremely rare, and there have been no similar reports. The factor of chronic cholecystitis by gallstones is one of the reasons, but only that usually do not occur intraabdominal hemorrhage. It remains possible that factors peculiar to a patient with LVAD contribute to the condition. The reasons for increased risk of bleeding, particularly gastrointestinal bleeding (GIB), in these patients are reported to be acquired Von Willebrand syndrome and arteriovenous malformation (AVM) . The continuous-flow ventricular pump of these LVADs induces shear stress to the blood vessels, which does not exist in a physiological heart movement, and reduces Von Willebrand factor activity by loss of high-molecular-weight multimers. And approximately 33–50% of all GIB episodes in patients with LVADs are reported to be due to AVMs. In these cases, angiogenesis-related signaling cascade leading to angiodysplasia caused by tumor necrosis factor alpha has been reported as the underlying mechanism. Interestingly, the patient also had refractory epistaxis, which has been reported to be caused by AVMs in patients with second-generation LVADs . However, neither the preoperative computed tomography nor the pathological findings revealed an AVM; this may be due to the intraoperative coagulation.
Laparoscopic approach is useful and safe in a patient with LVADs for abdominal surgery. We could perform LC for intraabdominal hemorrhage from gallbladder serosa safety. Jarvik 2000, type of LVAD, did not disturb the operating field because of its smaller size.
