Intraoperative severe hypoglycemia indicative of post-hepatectomy liver failure

We present the first reported case of a patient with intraoperative hypoglycemia, with no predisposing factors, that was indicative of post-hepatectomy liver failure due to liver injury. A 56-year-old man was hospitalized to undergo left lateral segmentectomy, cholecystectomy and T-tube choledocholithotripsy due to calculi in the intrahepatic and common bile ducts. His medical history was unremarkable. Three hours after surgery initiation, his glucose level decreased from 84 mg/dL to below detectable levels. We infused 20 % dextrose repeatedly until his glucose level returned to within normal limits. His aspartate aminotransferase and alanine aminotransferase levels increased to over 10,000 IU/L, and his blood urea nitrogen and creatinine levels increased postoperatively. Thus, we diagnosed post-hepatectomy liver failure and hepatorenal syndrome and treated the patient conservatively. This case illustrates that, if no other causative factors for severe hypoglycemia occurring during liver resection are present, the anesthesiologist should predict post-hepatectomy liver failure due to liver injury and inform the surgeon in order to enable rapid evaluation and treatment.     

Banking a fillet flap to aid in reconstruction following a hindquarter amputation

A hindquarter amputation and hemipelvectomy for recurrent malignancy presents a reconstructive challenge to the plastic surgeon. Tumour resection leaves a considerable defect, with exposure of bone, neurovascular structures, pelvic and abdominal organs. A free lower leg fillet flap is a recognised method of providing soft tissue coverage, but ischaemic time is often lengthy as described in the literature. We present a unique method of providing soft tissue coverage using a free lower leg fillet flap, and minimising ischaemic time by banking the flap on the ulnar artery during the hindquarter amputation and tumour resection.Level of Evidence: Level V, therapeutic study.     

Appendiceal Immunoglobulin G4-Related Disease Mimicking Appendiceal Tumor or Appendicitis: A Case Report

Immunoglobulin G4 (IgG4)-related disease is an autoimmune disease that forms tumorous lesions. Several cases involving various organs are reported, however, IgG4-related disease involving appendix has not been reported yet. In this report, we presented a case of IgG4-related disease of appendix, which raised a suspicion of appendiceal tumor or usual appendicitis and, therefore, led to unnecessary surgical resection. IgG4-related disease should be considered in the differential diagnosis for a mass-like swelling of the appendix, in order to avoid unnecessary surgery.
