title: Surgical treatment of shoulder instability with trans-subscapularis transfer of the biceps long tendon.

description: ABSTRACT Our objective is to describe the long biceps tendon transfer technique for the treatment of shoulder anterior instability. In this procedure, the long tendon of the biceps brachii is detached from the supraglenoid tubercle and transferred to the anterior edge of the glenoid cavity through a subscapularis tenotomy, reproducing the sling effect and increasing the anterior block. The technique is easy to perform and minimizes the risks of the coracoid process transfer. In conclusion, the transfer of the long tendon of the biceps brachii is an option for the treatment of glenohumeral instability.

title: Abbreviated preoperative fasting favours postoperative oral intake at lower hospital admission costs for cancer patients.

description: ABSTRACT Objective: to evaluate the feasibility of abbreviated fasting in oncologic colorectal surgeries, as well as the impact on the surgical outcome of the patients. Methods: prospective randomized comparative study with patients undergoing elective colorectal cancer surgeries from May to September 2017. Patients were randomized electronically into two groups according to the preoperative fast to be adopted: conventional or abbreviated. Results: of the 33 patients included, 15 followed the abbreviated fasting protocol and 18 the conventional fasting. Both groups had comparable profiles. No patient underwent mechanical preparation of the colon. In 69.7% of the cases, surgery involved low rectal dissection. The procedures were equivalent in relation to intraoperative variables and severe complications. The time to achieve complete oral intake was shorter for abbreviated fasting (10 versus 16 days, p=0.001), as well as the length of inhospital stay (2 versus 4 days, p=0.009). Hospital costs were lower in the abbreviated fasting (331 versus 682 reais, p&lt;0.001). The univariable analysis revealed a correlation between complete oral intake and abbreviated fasting [HR 0.29 (IC95%: 0.12-0.68] and abdominal distension [HR 0.12 (IC95% 0.01-0.94)]. After multivariable analysis, abbreviated fasting presented a lower time for complete oral intake [HR 0.39 (IC95%: 0.16-0.92]. Conclusion: the abbreviated preoperative fasting favors the metabolic-nutritional recovery, reducing the time for complete oral intake. The implementation of the abbreviation protocol reduces hospital admission costs.

title: Is the non-metastatic, locally advanced colon adenocarinoma a distinct biological tumor variant? A study based on pathological evaluation, immunohistochemical panel and survival.

description: ABSTRACT Objective: to evaluate the clinical and pathological differences between locally advanced colonic adenocarcinomas (LACA) with adhesions between adjacent organs or structures, and colonic adenocarcinomas with other clinical presentations. Methods: we conducted a retrospective study from a convenience sample of patients with colonic adenocarcinoma, pathological stage pT3, distributed according to clinical and pathological characteristics in three groups: locally advanced tumors (LACA), pT3 tumors without adhesions or distant metastases (SF) and tumors with metastatic disease (M1). We evaluated clinical and pathological characteristics and the expression of seven immunohistochemical markers related to proliferation/apoptosis, cell invasion/migration and metastasis. Results: we studied 101 patients: 30 LACA, 44 SF and 27 M1. Locally advanced tumors presented larger dimensions and were associated with increased lymphocyte infiltration rates, lower levels of bax expression, and CD 44v6 when compared with SF and M1 groups. We observed significant differences between LACA and M1 in relation to colonic location, histology, lymph node status and bax and CD44v6 expression. We found differences were observed between the three groups for tumor size and lymphocytic infiltrate. Survival was similar in the LACA and SF groups (p=0.66) and was lower in the M1 group (p&lt;0.001). Conclusion: the data suggest that locally advanced colonic adenocarcinomas with adhesions between adjacent organs or structures represent a distinct entity.

title: Implementation of a surgical screening system for urgent and emergent cases in a tertiary hospital.

description: ABSTRACT Objective: to evaluate the applicability of the "Timing of Acute Care Surgery" (TACS) color classification system in a tertiary public hospital of a developing country. Methods: we conducted a longitudinal, retrospective study in a single center, from March to August 2016 and the same period in 2017. We opted for the selection of four surgical specialties with high demand for emergencies, previously trained on the TACS system. For comparisons with the previous classifications, we considered emergencies as reds and oranges and urgencies, as yellow, with an ideal time interval for surgery of one hour and six hours, respectively. Results: non-elective procedures accounted for 61% of the total number of surgeries. The red, orange and yellow classifications were predominant. There was a significant improvement in the time before surgery in the yellow color after the TACS system. Day and night periods influenced the results, with better ones during the night. Conclusion: this is the first study to use the TACS system in the daily routine of an operating room. The TACS system improved the time of attendance of surgeries classified as yellow.

title: Dietary supplementation with Camu-Camu versus sleeve gastrectomy in Wistar rats weight control.

description: ABSTRACT Objective: to compare the effects of the hydroalcoholic extract from the peel of Camu-Camu, a fruit plant belonging to the Myrtaceae family, widely distributed in the Amazon basin, with those of sleeve gastrectomy, on the weight and glycemia of Wistar rats. Methods: twenty-four Wistar rats underwent obesity induction through a hyperlipid diet for eight weeks (fat period), and were randomized into three groups: Control Group (CG), Camu-Camu Group (CCG) and Bariatric Surgery Group (BSG). After this period, all animals returned to a normal diet and the intervention period began: CG did not undergo any intervention beyond diet change; CCG animals underwent gavage procedure for administration of Camu-Camu hydroalcoholic extract, 1g/kg/day, for four weeks; and the BSG was submitted to the surgical procedure of sleeve gastrectomy. We followed all animals for four weeks. Results: there was only one loss in BSG due to a gastric fistula. We observed significant variations in the animals’ mean weight: the CG evolved with weight gain even after the withdraw of the hypercaloric diet, while the other two groups presented weight reduction. BSG presented a significant reduction of weight and BMI (p&lt;0.05); CCG achieved a significant reduction only of the BMI (p&lt;0.05). There were no statistically significant changes in the glycemic levels. Conclusion: in spite of reducing weight, the crude hydroalcoholic extract of the Camu-Camu peel was not able to be as efficient as sleeve gastrectomy in the control of body weight in Wistar rats.

title: Safety and quality in surgery: surgeons' perception in Brazil.

description: ABSTRACT Objective: to evaluate the perception of surgeons, members of the Brazilian College of Surgeons (CBC), on safety and quality issues in surgery, based on projects of Brazilian Ministry of Health (MS), CBC, World Health Organization (WHO), and American College of Surgeons (ACS). Methods: a questionnaire based on WHO, CBC, and ACS initiatives was sent to all active and non-active CBC members, using Survey Monkey, in March 2018. Results: out of 7,100 members, 171 professionals answered the questionnaire. Out of these, the majority (63.2%) declared to perform general surgery, 88.9% indicated knowing the project called Safe Surgery developed by MS, 73.1%, the CBC manual, and 14.6%, the ACS Strong for Surgery. Among those who indicated knowing the MS project, 73.1% said that they were accustomed to use it as a routine, and, among those who indicated knowing the CBC manual, 46.2% said that they were accustomed to use it. Most of the surgeons (81.3%) indicated that they had experienced severe surgical failures, being failures related to surgical material (49.7%) and presence of foreign bodies (8.2%) the most common ones. There were distinct opinions on who was responsible for checking over the checklist. Conclusion: the importance of safety and quality in surgery is well known by surgeons, but the practice is varied. Serious adverse events had been experienced by many surgeons, mainly related to surgical material and foreign bodies. The concept of interdisciplinarity did not seem to be common practice. Data indicated the need to develop education projects and the obligation of audits.

title: Can the Zuckerkandl tubercle assist in the location of the inferior laryngeal nerve during thyroidectomies?

description: ABSTRACT Objective: to evaluate whether the lateral projection of the thyroid gland, called Zuckerkandl's tubercle (ZT), can assist the surgeon in identifying the inferior laryngeal nerve during conventional open thyroidectomy. Methods: we conducted a prospective study with 51 patients submitted to thyroidectomy, with a total of 100 resected thyroid lobes, and observed the presence or absence of ZT in sufficient dimensions to be identified without image magnification, its base and height, its location in the gland, and its anatomical relationship with the inferior laryngeal nerve. Results: ZT was present in 68 of the 100 thyroid lobes analyzed (68%). The mean base was 6.7mm on the right side and 7.1mm on the left side, and the average height was 5.7mm on the right side and 6.1mm on the left side. In most of the lobes studied, the tubercle had a minimum height of 5mm (55.9%), with no significant difference between the right and left lobes of the thyroid gland. During surgery, 100% of the identified ZTs were anterior to the inferior laryngeal nerve, just below the nerve entry in the larynx. Conclusion: the ZT is a quite frequent entity and large enough to serve as an intraoperative anatomical reference for the inferior laryngeal nerve, next to its entry in the larynx, along with other anatomical references.

title: Gastric cancer in young adults: a worse prognosis group?

description: ABSTRACT Objective: to evaluate the clinical and pathological characteristics and survival of young patients with gastric cancer, regardless of the intention of treatment. Methods: we conducted a retrospective analysis of all gastric cancer patients undergoing any surgical treatment between 2008 and 2017. We considered patients under 45 years old as young adults and those over 45 years old, as of advanced age. Results: of the 875 patients evaluated, 84 (9.6%) were young adults and 791 (90.4%) were older. Younger patients were associated with female gender (p&lt;0.001), lower Charlson score (p=0.002), ASA I/II (p&lt;0.001), diffuse Lauren type (p&lt;0.001) and poorly differentiated tumors (p&lt;0.001). There was no difference between groups regarding treatment intention (palliative versus curative) (p=0.267) and cTNM clinical stage (p=0.120). Disease-free survival was worse in younger individuals (p=0.049), but overall survival was similar between groups (p=0.578). Multivariate analysis identified total gastrectomy, pT3/T4, pN+, and diffuse Lauren type as prognostic factors associated with worse disease-free survival and overall survival. Age was not an independent factor associated with worse prognosis. Conclusion: although younger patients had lower disease-free survival, overall survival was similar between groups, and age was not a significant independent prognostic factor.
