Table of Contents

A 78-year-old man underwent total colonoscopy because of positive fecal occult blood test. Two lateral spreading tumors (LST), approximately 35 mm and 40 mm in size, were detected in the cecum and transverse colon, respectively. Both lesions were endoscopically diagnosed as adenoma or focal cancer in adenoma, and therefore considered good candidates for endoscopic resection.

Initially, endoscopic submucosal dissection (ESD) was attempted for en bloc resection of the LST located in the cecum. During the procedure, although no definite perforation was recognized, the patient became aware of marked abdominal distension, and then developed hypotension, his blood pressure decreasing to 80 mm Hg. The procedure was immediately discontinued, and emergency abdominal computed tomography (CT) demonstrated a large pneumoperitoneum with collapse of the inferior vena cava ([Fig. 1]). Paracentesis was performed for decompression with a 20 gauge puncture needle. The patient’s symptoms were relieved, and the blood pressure and diameter of the inferior vena cava returned to normal immediately after decompression. The patient recovered uneventfully after conservative treatment, including withholding oral intake, intravenous administration of antibiotics, and hyperalimentation.

In order to completely remove large colorectal tumors endoscopically en bloc, a novel technique of ESD instead of conventional endoscopic mucosal resection (EMR) has been developed [1]. This technique is reportedly associated with a significant incidence of complications, such as perforation and bleeding, in comparison with conventional EMR [1] [2]. However, most perforations that occur during ESD are small and can be managed conservatively with endoclip placement if recognized immediately. In the present case, the exact site of perforation, which may have been a mini-perforation, could not be detected endoscopically, and thus pressurized air resulted in increased intra-abdominal pressure. In general, increased intra-abdominal pressure can have numerous adverse physiologic effects, which may include decreased venous return, decreased cardiac output, and altered ventilation-perfusion relationships [3] [4]. Tension pneumoperitoneum should be suspected in all patients who develop circulatory and/or respiratory collapse with acute abdominal distension during or after endoscopy, especially for treatments that carry a high risk of perforation [3]. Early identification and prompt treatment with needle decompression are important in order to avoid serious sequelae such as abdominal compartment syndrome leading to multiple organ failure [4].
