RESUMO

BACKGROUND: Although the use of lateral intercostal artery perforator (ICAP) flaps for immediate breast reconstruction has been widely described, data on the use of the anterior ICAP (AICAP) flaps for this indication are limited. In this context, we describe the results of anatomical study and our clinical experience with AICAP flaps for breast reconstruction. METHODS: In this study, the location and characteristics of the AICAPs were dissected in 12 female adult formalin-preserved hemitrunks and two fresh-frozen cadavers. Fourteen patients (mean BMI 23) underwent partial breast resection for a quadrant breast cancer followed by breast reconstruction with an intercostal perforator flap. The mean resection size was 6 × 5 × 5.5 cm (range 3-8 × 3.5-7 × 4-8 cm).The main outcome measures were pre-operative and postradiotherapy health-related quality of life assessed with the BREAST-Q reconstruction survey. RESULTS: According to anatomical study, at least one perforator was found in each third of hemitrunks dissected. The mean of perforator size was in diameter 0.42 ± 0.05 mm and in length 3.1 ± 0.36 cm. In clinical outcomes, the mean of flap size was 16 × 5 × 3 cm (range 14-19 × 3-8 × 2-5 cm). The mean surgical time was 120 min (range 109-125 min). Only one partial flap failure was detected. No postoperative changes in breast size were observed, although soft tissue changes were observed in four patients after radiotherapy. The mean BREAST-Q scores changes were 0 in satisfaction with the breast, 5 in satisfaction with outcome, 0 in psychosocial well-being, 6.15 in sexual well being, and 34.69 in physical well-being. CONCLUSIONS: Based on this anatomical and clinical study, we found AICAP flap has a consistent vascularization with good perforators. And moreover, it is suitable for partial breast reconstruction (quadrantectomy) and does not appear to negatively impact patient satisfaction.

RESUMO

BACKGROUND: Reconstruction of the anterior thorax is complex because of the presence of aesthetically important areas such as the breast, sternum, and upper abdomen. For this reason, a wide variety of pedicled perforator flaps have been described. The anterior intercostal perforator flap is one of these perforators flaps and is valuable for use in breast reconstruction surgery. METHODS: The location and characteristics of the anterior intercostal perforators were evaluated both anatomically and radiologically. The anatomical study was conducted in a set of 14 hemitrunk cadavers, and the radiologic study was performed retrospectively from a randomly selected set of images obtained from 30 female patients who underwent thoracic computed tomographic angiography for other health problems at the authors' institution during the year 2015. The findings were then compared. RESULTS: A total of 60 perforators in 14 hemitrunks were identified and mapped. Perforators were found in all hemithoraces. The lateral third donor location was the most reliable zone, containing larger and more numerous perforators compared with the other donor regions. According to the radiologic study, a total of 164 perforators in 30 computed tomographic angiographs were identified and mapped. Perforators were found in all thoraxes. CONCLUSIONS: The authors found that the intercostal perforator flap has a consistent vascularization. Computed tomographic angiography is less reliable than dissection in identifying the number of perforators. The authors' findings suggest that intercostal perforator flaps are reliable and consistent flaps for reconstruction of the upper trunk.

RESUMO

Background Clinical effectiveness and safety of biological and synthetic adhesives in digestive closures have been evaluated. Their use is becoming more prevalent, as rigidity and inflexibility are its more remarkable weaknesses. However, little is known about their role in gastric and anastomotic closures. Moreover, usefulness of novel flexible types of synthetic adhesives as n-butyl-cyanoacrylate has not been assessed yet. Materials and Methods One centimeter long gastrotomy was performed in 24 male Wistar rats, which were divided depending on the type of closure method employed: manual USP 5/0 silk interrupted suture versus sutureless closure with Histoacryl Flexible (n-butyl-cyanoacrylate with softener) or Histoacryl Double Component (n-butyl-cyanoacrylate with softener and hardener). Microscopic evaluation of the suture viability and integrity was performed, and adhesion formation during the cicatrization process were assessed. During an 8-week follow-up clinical and histopathological aspects as well as hematologic and inflammatory biomarkers were studied. Results No differences among groups where found in any of the clinical, analytical, or histopathological issues assessed except for a higher incidence rate of adhesions in the Histoacryl Double Component group when compared with hand-sewn suture group (P = .04). Our results support experimental studies in large mammals (pigs) for further study of sutureless hollow viscera closure.

RESUMO

INTRODUCTION: Adrenohepatic fusion means union between the adrenal gland and the liver, intermingling its parenchymas. It is not possible to identify this condition by image tests. Its presence implies radical and multidisciplinar approach. PRESENTATION OF CASES: We report two female cases of 45 and 50 years old with clinical virilization and palpable mass on the abdominal right upper quadrant corresponding to adrenocortical carcinoma with hepatic fusion. The contrast-enhanced tomography showed an indistinguishable mass involving the liver and the right adrenal gland. In the first case, the patient had a two-time operation, the former removing only the adrenal carcinoma, and the second performing a radical surgery after an early relapse. In the second case, a radical right en bloc adrenohepatectomy was performed. Both cases were pathologically reported as liver-infiltrating adrenal carcinoma. Only in the second case the surgery was radical effective as first intention to treat, with 3 years of disease-free survival. DISCUSSION: ACC is a rare entity with poor prognosis. The major indicators of malignancy are tumour diameter over 6cm, local invasion or metastasis, secretion of corticosteroids, virilization and hypertension and hypokalaemia. The parenchymal fusion of the adrenal cortical layer can be misdiagnosed as hepatocellular carcinoma with adhesion with the Glisson capsule. AHF in such cases may be misinterpreted during surgery, what may impair its resectability, and therefore the survival. The surgical treatment must be performed en bloc, often using liver vascular control. Postoperative treatment must be offered immediately after surgery. CONCLUSION: We report two consecutive rare cases of adrenohepatic fusion in giant right adrenocortical carcinoma, not detectable by imaging, what has important implications for the surgical decision-making. As radical surgery is the best choice to offer a curative treatment, it has to be performed by a multidisciplinary well-assembled team, counting with endocrine and liver surgeons, and transplant surgeons in case of vena cava involvement, in order to maximize the disease-free survival.

RESUMO

BACKGROUND: The role of bactibilia as a risk factor for an unfavorable outcome during biliary disease or surgical procedures remains obscure. Our aim was to identify possible risk factors for bactibilia and their possible relations to complications after elective cholecystectomy. As secondary aims, composition and antibiotic resistance patterns were studied. METHODS: Bile and gallbladder mucosa samples from 358 elective cholecystectomies were collected prospectively between June 2009 and June 2012. Ordinary microbiologic cultures and antibiograms were performed. All pre-operative factors associated with bactibilia were studied by stepwise logistic regression multivariable analysis. RESULTS: The bacteria isolated most frequently from 103 positive cultures were Escherichia coli (21.3%), Enterococcus spp. (14.7%), and Enterobacter spp. (14.7%) with a global amoxicillin-clavulanic acid resistance rate of 53.7%. Age >65 y, male gender, previous instrumentation or disease of the biliary tract, and high American Society of Anesthesiologists score were independent risk factors. No correlation was found between bactibilia and surgical complications. CONCLUSIONS: Although the influence of bactibilia in developing surgical complications is limited, its composition and the high rate of resistance can be influential enough to modify antibiotic treatment in biliary tract infections, especially in high-risk patients.
