The impact of COVID-19 pandemic on breast surgery in Italy: a multi-centric retrospective observational study.

COVID-19 pandemic had an impact on surgical activities. The aim of this multi-centric, retrospective study was to evaluate the impact of the COVID-19 pandemic on breast surgery. The patients who operated during the pre-pandemic year 2019 were compared to those operated in 2020. Fourteen Breast Care Units provided data on breast surgical procedures performed in 2020 and 2019: total number of breast-conserving surgery (BCS), number of 1st level oncoplastic breast surgery (OBS), number of 2nd level OBS; total number of mastectomies, mastectomies without reconstruction, mastectomies with a tissue expander, mastectomies with direct to implant (DTI) reconstruction, mastectomies with immediate flap reconstruction; total number of delayed reconstructions, number of expanders to implant reconstructions, number of delayed flap reconstructions. Overall 20.684 patients were included: 10.850 (52.5%) operated during 2019, and 9.834 (47.5%) during 2020. The overall number of breast oncologic surgical procedures in all centers in 2020 was 8.509, compared to 9.383 in 2019 (- 9%). BCS decreased by 744 cases (- 13%), the overall number of mastectomies decreased by 130 cases (- 3.5%); mastectomy-BCS ratio was 39-61% in 2019, and 42-58% in 2020. Regarding immediate reconstructive procedures mastectomies with DTI reconstruction increased by 166 cases (+ 15%) and mastectomies with immediate expander reconstruction decreased by 297 cases (- 20%). Breast-delayed reconstructive procedures in all centers in 2020 were 142 less than in 2019 (- 10%). The outburst of the COVID-19 pandemic in 2020 determined an implemented number of mastectomies compared to BCS, an implemented number of immediate breast reconstructions, mainly DTI, and a reduction of expander reconstruction.

Defect-oriented reconstruction after transoral robotic surgery for oropharyngeal cancer: a case series and review of the literature.

Transoral robotic surgery (TORS) is a fascinating new technique that has been shown to be a safe and feasible treatment for selected oropharyngeal cancers. Furthermore, TORS might offer some advantages in selected locoregionally advanced cancers. Thus, the patient selection is the keypoint for the useful application of TORS. However, the reconstruction of large oropharyngeal defects is challenging due to the restoration of velopharyngeal competency and swallowing. Moreover, the absence of mandibular splitting increases the difficulties faced by reconstructive surgeons. The paradigm for oropharyngeal reconstruction has undergone changes paralleling reflecting the overall change in the trend of the treatment alternatives over the last few decades. Flap choice and harvesting should be tailored to obtain significant advantages both in functional terms and for easy insetting. In this review, we analyse the strengths and weaknesses of the various flaps used in TORS framework with particular regards on our preliminary experience.

Superficial swab versus deep-tissue biopsy for the microbiological diagnosis of local infection in advanced-stage pressure ulcers of spinal-cord-injured patients: a prospective study.

OBJECTIVE: To assess the predictive value of superficial ulcer swab culture to make a microbiological diagnosis of deep wound infections in spinal cord injury (SCI) patients with advanced-stage pressure ulcers. METHODS: From July 2011 to February 2014, we performed a prospective, single-centre study on adult SCI patients undergoing scheduled surgical debridement and reconstruction for advanced-stage pressure ulcers, at Montecatone Rehabilitation Institute, a 150-bed hospital dedicated to SCI care. Three superficial ulcer swabs were preoperatively collected using the Levine technique, then sent for culture. In surgery, multiple bone and soft-tissue specimens were taken and sent for culture and histological examination. No antibiotics were administered before surgery. The results of swabs and intraoperative specimens were compared. RESULTS: In all, 116 patients were included, median age 49 years; a majority were males with post-traumatic paraplegia. According to intraoperative specimen cultures, the most common micro-organisms were Staphylococcus aureus, Proteus mirabilis, and Pseudomonas aeruginosa, found in 31, 27, and 16 cases, respectively. Concordance between superficial swabs and intraoperative specimen culture was found in only in 25 out of 116 cases (22%). The main reason for non-concordance was the yielding of different micro-organisms (41 out of 116); false negatives (swab negative/intraoperative positive) accounted for 31 out of 116 and false positives (swab positive/intraoperative negative) for 19 out of 116. When compared with intraoperative specimens, sensitivity and specificity of the swab culture were 80% and 54%, respectively. CONCLUSIONS: Our results confirm that in patients with advanced-stage pressure ulcers, the cultures of a superficial ulcer swab are not useful in either the diagnosis of a superinfection or the prediction of the role of involved micro-organisms.

Vascular pedicle ossification of free fibular flap: is it a rare phenomenon? Is it possible to avoid this risk?

Free fibula flap is the most common free tissue transfer for maxillary and mandibular reconstructions. The distal part of the harvested bone is transferred, while the proximal part is removed by sub-periosteum dissection. The vascularized periosteum attached to the vascular pedicle has osteogenic potential. 61 patients reconstructed with free fibula flaps were divided in 2 groups: 41 flaps performed with a standard technique and 20 flaps performed by dissecting the periosteum from the pedicle. Patients were followed up with orthopantomography and CT scan at 6, 12, 18 and 24 months after surgery. The minimum follow-up time was 18 months. With retrospective analysis of the first group we diagnosed 7 pedicle ossifications on 41 reconstructions (17%). In the second group, no pedicle ossification was observed (p < 0.05). The dissection of periosteum from the vascular pedicle of free fibula flaps avoids the risk of ossification.

Cross-leg as salvage procedure after free flaps transfer failure: a case report.

Posttraumatic wounds of the lower leg with soft tissue defects and exposed fractures are a reconstructive challenge due to the scarce availability of local tissues and recipient vessels. Even when a free tissue transfer can be performed the risk of failure remains considerable. When a free flap is contraindicated or after a free flap failure, the cross-leg flap is still nowadays a possible option. We report a case of a male with a severe posttraumatic wound of the lower leg with exposed tibia fracture firstly treated with two consecutive latissimus dorsi muscular free flaps, failed for vascular thrombosis; the coverage was then achieved with a cross-leg flap with acceptable results.

Head and neck cancer in elderly patients: is microsurgical free-tissue transfer a safe procedure?

The safety and success of microvascular transfer have been well documented in the general population, but the good results achieved with the use of free flaps in elderly patients have received little attention. This study sought to identify differences in complications, morbidity and functional outcomes between elderly (≥ 75 years) and younger (< 75 years) patients treated surgically for advanced head and neck cancer using the Head and Neck 35 module of the European Organisation for Research and Treatment of Cancer quality of life questionnaire. Patient treatment consisted of composite resection, including excision of the primary tumour with ipsilateral or bilateral neck dissection and microvascular reconstruction. Eighty-five microvascular tissue transfers were performed to reconstruct major surgical defects. Postoperative radiation therapy was performed when indicated. Total flap loss occurred in three cases in elderly patients and two cases in younger patients. The rates of major surgical complication were 9% in young patients and 11% in elderly patients. No significant difference was observed between the two groups in the rates of major and minor flap complications, morbidity or long-term functional outcome. The results of the present analysis indicate that free-flap microvascular reconstruction can be considered a safe procedure in elderly patients with head and neck cancer.

Abdominal wall transplantation: surgical and immunologic aspects.

Abdominal wall transplantation is a type of composite tissue allograft that can be utilized to reconstitute the abdominal domain of patients undergoing intestinal transplantation. We have presented herein combined experience and long-term follow-up results of a series of abdominal wall transplants performed at 2 institutions. A total of 15 abdominal wall transplants from cadaveric donors were performed in 14 patients at the end of intestinal transplant surgery or, in 2 cases, a few days after the primary intestinal transplant. The vascular supply was through the inferior epigastric vessels, from the iliac vessels in 12 cases and via a microsurgical technique in 3 cases. Immunosuppression consisted of induction with alemtuzumab and maintenance treatment with tacrolimus monotherapy. Two grafts lost to vascular thrombosis were removed. Five patients are still alive, although all deaths were unrelated to the abdominal wall transplant. There were 3 episodes of abdominal wall graft rejection, treated with steroids; the abdominal wall graft and the intestinal grafts experienced rejection independent from each other. In summary, abdominal wall transplantation is a feasible technique for recipients of intestinal or multivisceral transplants, when the closure of the abdominal cavity by primary intention is technically impossible.

Abdominal wall transplantation with microsurgical technique.

Many patients undergoing intestinal or multivisceral transplantation have a past history of complete midgut removal with the loss of the domain of the abdominal compartment or have severely damaged abdominal walls from repeated laparotomies, tumours or enterocutaneous fistulae. These patients may encounter severe abdominal wall closure problems at the end of transplantation, resulting in increased morbidity and mortality. It is, therefore, of paramount importance to properly cover transplanted organs in order to reduce postoperative complications. Abdominal wall transplantation was recently proposed for closure of patients undergoing both small-bowel and multivisceral transplantation: the results are encouraging. However, the technical procedure proposed requires the procurement of long segments of iliac vessels as far as the vena cava and the aorta. Since donor multiorgan procurement involves many surgical teams, the removal of these vessels, with the abdominal graft, led to their unavailability for vascular surgeons. Here we present three consecutive cases of abdominal wall transplantation in which, by taking advantage of microsurgical experience, we were able to carry out a transplantation of the abdominal wall by direct anastomosis of the epigastric vessels, obtaining a very good outcome.
