We report dextran-induced anaphylactoid reactions (DIAR) subsequent to rapid infusion of Rheomacrodex (dextran 40) in two patients, a 67 year old man with gastric cancer undergoing distal gastrectomy and a 47 year old man with transverse colon cancer undergoing colectomy. Both showed sudden tachycardia, hypotension and skin flush, which were treated with epinephrine or etilephrine administration. Most cases of severe DIAR are immune complex anaphylaxis mediated by dextran-reactive antibodies (DRA) of the IgG class, which are considered to arise mainly in response to immunization with dextran-cross-reactive bacterial polysaccharides in the gastrointestinal tract. High titers of DRA have previously been reported in gastric ulcer patients with pyloric stenosis, suggesting bacterial polysaccharides permeation through the luminal wall which may easily occur in the presence of local inflammation or ulcer. Although serum DRA titers in our patients have not been examined, inflammation or ulcer around the tumor might have played a role in producing high titers of DRA. In patients suspected of gastrointestinal ulcer or inflammation, including cancer, dextran administration is not preferable or should be avoided, unless hapten-dextran preparation is used for the prophylaxis of severe DIAR.

We encountered three cases of perioperative anaphylaxis identified by using skin-prick tests. [Case 1] A 43-year-old woman was scheduled to undergo elective laparoscopic subtotal gastrectomy under general anesthesia for gastric tumor. However, the procedure was cancelled because of anaphylaxis that was noted at the beginning of the surgery. We performed a skin-prick test and observed a positive reaction with ro- curonium. [Case 2] A 79-year-old man underwent laparoscopic colon resection under general anesthesia for colon cancer. Anaphylaxis was noted at the end of surgery. We performed a skin-prick test and observed a positive reaction with sugammadex. [Case 3] A 44-year-old woman underwent myomectomy under general anesthesia for a uterine fibroid. Anaphylaxis was noted approximately 10 minutes after the beginning of surgery. We performed a skin-prick test and noted a positive reaction with latex. It is difficult to identify the reason for anaphylaxis during surgery under general anesthesia because various agents may be responsible for the anaphylactic reaction. Anaphylaxis during surgery is a rare but life-threatening event and it is important to identify the causative agent for anaphylaxis.

A 69-year-old man underwent right hemicolectomy and D3 lymphadenectomy for transverse colon cancer in 2009. Under the postoperative pathological diagnosis of Stage IIIb (pT3pN2cM0) cancer, he was given 8 courses of adjuvant chemotherapy with capecitabine. After the chemotherapy, in April 2013, we detected recurrence of the multiple liver and lung metastases; thus, we administered modified 5-fluorouracil, Leucovorin, oxaliplatin (mFOLFOX6) and bevacizumab. Six courses of oxaliplatin infusion were completed uneventfully. However, 3 min after starting the seventh infusion courses, the patient experienced cardiopulmonary arrest. We immediately performed cardiopulmonary resuscitation. The patient's anaphylaxis symptoms resolved after treatment with intravenous epinephrine. He was discharged 3 days after the event with no further complications. Clinicians should be aware that oxaliplatin-induced anaphylactic shock often occurs during the eighth infusion cycle and that this severe hypersensitivity reaction is difficult to predict and prevent.
