RESUMEN
PURPOSE: This systematic review aims to provide an overview of the literature on the effect of hyperbaric oxygen therapy (HBOT) on symptoms of local late radiation toxicity (LRT) in patients treated for breast cancer. METHODS: A systematic search was performed in September 2021. All studies with a sample size of ≥10 patients reporting the effect of HBOT for symptoms of LRT after radiotherapy of the breast and/or chest wall were included. The ROBINS-I tool was used for critical appraisal of methodological quality. The toxicity outcomes pain, fibrosis, lymphedema, necrosis/skin problems, arm and shoulder mobility, and breast and arm symptoms were evaluated. RESULTS: Nine studies concerning a total of 1308 patients were included in this review. Except for one study, sample sizes were small. Most studies had inadequate methodology with a substantial risk of bias. Post-HBOT, a significant reduction of pain was observed in 4/5 studies, of fibrosis in 1/2 studies, and of lymphedema of the breast and/or arm in 4/7 studies. Skin problems of the breast were significantly reduced in 1/2 studies, arm- and shoulder mobility significantly improved in 2/2 studies, and breast- and arm symptoms were significantly reduced in one study. CONCLUSION: This systematic review indicates that HBOT might be useful for reducing symptoms of LRT in breast cancer patients, however evidence is limited. A randomized controlled trial in a larger cohort of patients including a combination of patient- and clinician-reported outcome measures would be valuable to assess the effect of HBOT on symptoms of LRT.

Dermal injection of fillers is a popular and relatively safe aesthetic procedure. Severe complications are rare, but they do occur. One of the most threatening complications after dermal filler injection is skin necrosis due to vascular occlusion. Different treatment options are available, including the use of hyperbaric oxygen (HBO2) therapy. A 46-year-old female received facial dermal filler injections with calcium hydroxylapatite at an aesthetic clinic. A few days after injection she developed a burning pain, numbness of the skin and white discoloration in the injected area. Two days after injection treatment was started with hyaluronidase and warm compresses. In addition, the patient received prednisolone, sildenafil and nifedipine. After the start of these treatments, the pain, numbness and discoloration of the skin persisted. Because of dermal ischemia and to improve healing she was referred for HBO2. Treatment consisted of 10 sessions of 100% oxygen for 90 minutes in a multiplace chamber at 2.5 atmospheres absolute pressure. During HBO2 the discoloration resolved, pain and numbness disappeared, and the tissue healed completely. After a six-month follow-up she had an excellent cosmetic outcome. Given the pathophysiologic mechanisms of vascular complications after dermal filler injection, HBO2 should be considered when treating these complications.

BACKGROUND: Laparoscopic cholecystectomy is frequently complicated by gallbladder perforation and loss of bile or stones into the peritoneal cavity. The aim of this study was to compare the use of ultrasonic dissection and electrocautery with respect to the incidence of gallbladder perforation and intraoperative consequences. METHODS: Between January 1998 and January 2000, 200 patients undergoing elective laparoscopic cholecystectomy were randomized to electrocautery or ultrasonic dissection of the gallbladder. The main outcome measures were gallbladder perforation, operating time and the number of times the lens was cleaned. Univariate and multivariate analyses were performed. RESULTS: The perforation rate differed significantly: 16 per cent for ultrasonic dissection (n = 96) and 50 per cent for electrocautery (n = 103) (P < 0.001). The operating time of the least experienced surgeons, who had performed fewer than ten laparoscopic cholecystectomies, was significantly shorter when ultrasonic dissection was used, compared with electrocautery. The number of times the lens needed to be cleaned was significantly lower when ultrasonic dissection was used in complicated gallbladders (P < 0.035). At logistic regression analysis, the risk of perforation in the electrocautery group was about four times higher (odds ratio 0.26, P < 0.001) than that in the ultrasonic group. When the groups were matched for prognostic factors, including body mass index and surgical experience, the results were similar to those obtained with univariate and multivariate analysis. CONCLUSION: The use of ultrasonic dissection in laparoscopic cholecystectomy reduces the incidence of gallbladder perforation and helps the operation to progress. Less experienced surgeons benefit most from ultrasonic dissection, particularly in complicated intraoperative circumstances.
