Interestingly, we observed a higher complication rate in patients with a postoperative lactate level >3 mmol/L.
We observed a wound complication rate of 20% in our study, which is similar to series using postoperative EBRT alone [ 27, 31] and compares favourably with series using preoperative EBRT [ 19, 27] indicating that the use of an IOERT boost does not increase the wound complication rate.
We observed an overall complication rate of 33% with four cases of superficial epidermolysis that spontaneously healed and three cases of partial flap loss ranging from 10 to 50% that required surgical revision by means of skin graft (two cases) or ALT free flap (one case).
In our consecutive 100 cases, we observed a variety of complications known to be associated with the bone transport technique.
By using standardized definitions to evaluate the incidence and severity of complications (particularly in obese patients), we observed a lower incidence of complications than reported in the literature [ 10, 11].
Conclusions: We observed a low incidence of perioperative complications in our patient population, as well as a very low incidence of postoperative complications compared with that reported in the reviewed articles, no serious complications in any patient who perform percutaneous tracheostomy were observed.
We observed a trend toward more early complications in LRYGB than in LSG (17.2% vs 8.4%; P = 0.067).
Considering chronic renal failure and chemotherapy as proxies of non-nutritional anemia (usual complications), we observed a significantly increased K0 (0.63), suggesting a possible under-coding of the condition.
We observed a reduction of pulmonary infectious complications, a normalisation of plasma GSHPx activity, increased tissue selenium and zinc concentrations, an improved wound healing, and a similar reduction of normalised length of stay.
Despite an aggressive surgical strategy with extensive bony decompression, we observed a low rate of surgery-related complications or co-morbidities, which is highly comparable with previous reports [ 1, 9].
We observed a lower number of patients with complications in the ScvO2 group compared to the control group, however it did not reach statistical significance (ScvO2 group: 10 vs. control group: 19; p = 0.07).
