Treatment of Giant Esophageal Epiphrenic Diverticulum Using Robotic-Assisted Surgery.

Epiphrenic diverticulum is a rare condition associated with esophageal motor disorder, and it is often asymptomatic, with a well-established surgical indication. The present study aims to report a case of a giant epiphrenic diverticulum in a 68-year-old male patient who, due to the symptoms, opted for surgical treatment using the daVinci® system. Robotic surgery consisting of esophageal diverticulectomy with cardiomyotomy was performed. The patient had an excellent recovery with an abbreviated hospitalization, return to food, and satisfactory routine activity.

Prevalence of Frailty in Patients Undergoing Cardiac Valve Surgery: Comparison of Frailty Tools

Abstract Background There is no consensus among tools for assessing frailty. Objective To evaluate the prevalence of frailty according to different tools in patients referred for elective valve cardiac surgery. Methods This is a cross-sectional study. All patients were ≥ 18 years of age, clinically stable. The following patients were excluded: those unable to perform the tests because of physical, cognitive, or neurological limitations; those requiring non elective/emergency procedures or hemodynamic instability. During the preoperative cardiology visit, frailty was assessed by the Short Physical Performance Battery (SPPB), the Frailty Deficit Index (FDI), handgrip strength, and gait speed 3m. For the entire analysis, the statistical significance was set at 5%. Results Our cohort consisted of 258 subjects. From the total cohort, 201 were ≤ 70 years of age (77.9%), the predominant etiology according to rheumatic disease (50.7% vs 8.8%; p=0.000) with double mitral lesion (24.9% vs 0%; p=0.000). Frailty was present in 32.9% according SPPB, 29.1% with reduced muscular strength. and 8.9% with FDI. Handgrip strength was weaker in elderly patients (26.7 vs 23.6; p=0.051) and gait speed was lower in the younger group, in which 36% were considered frail (36% vs 14%; p=0.002). Variables associated with frailty were age ≥ 70 years, female gender, aortic stenosis, and regurgitation. Conclusion Frailty in adult patients who will have elective heart valve surgery is present even in the younger groups, although the older group with comorbidities are more frail. Frailty was more clearly shown by the SPPB than by the FDI and handgrip tests.

Laser therapy, used in a specific dose, modulates pulmonary inflammatory processes in an experimental model of sepsis in rats / O uso da laserterapia em dose específica modula o processo inflamatório pulmonar em um modelo experimental de sepse em ratos / El uso de la láserterapia en dosis específica modula el proceso inflamatorio pulmonar en un modelo experimental de sepsis en ratones

ABSTRACT This study aimed to determine the effectiveness of LLLT in decreasing the lung inflammatory process in septic rats. A total of 32 male Wistar rats were divided into four groups (n=8): control group (CG), sepsis 24h (S24), sepsis and LLLT with 30 J/cm² (S24L30); sepsis and LLLT with 65 J/cm² (S24L65). The irradiation was performed immediately after surgery in the anterior region of the trachea and ventral regions of the chest, bilaterally, just below the ribs. Histological analysis of lung tissue was performed and the number of inflammatory cells was quantified. The S24 group showed an increase of inflammatory cells compared to the CG (p <0.01); S24L30 increased the number of inflammatory cells, while S24L65 decreased this number compared to S24 (both p<0.05); S24L65 had a lower number of inflammatory cells compared to S24L30 (p<0.01). In conclusion, LLLT at a specific energy dose (30J / cm²) was capable of decreasing the number of inflammatory cells in acute lung tissue inflammation due to sepsis.

RESUMO O objetivo do estudo foi determinar a eficácia da LLLT na diminuição do processo inflamatório pulmonar em ratos sépticos. Foram utilizados 32 ratos machos Wistar divididos em quatro grupos (n=8): controle (CG); sepse 24h (S24); sepse e tratamento com LLLT 30 J/cm² (S24L30); sepse e tratamento com LLLT 65 J/cm² (S24L65). A irradiação foi realizada imediatamente após a cirurgia na região anterior de traqueia e nas regiões ventrais do tórax, bilateralmente, logo abaixo das costelas. Foi realizada análise histológica do tecido pulmonar e o número de células inflamatórias foi quantificado. O grupo S24 apresentou um aumento de células inflamatórias comparado ao CG (p <0,05); S24L30 aumentou o número de células inflamatórias, enquanto S24L65 diminuiu este numero em relação ao S24 (ambos p <0,05); S24L65 diminui o numero de células inflamatórias comparado ao S24L30 (p<0.01). Concluiu-se que LLLT em dose específica de energia (30J/cm²) foi capaz de diminuir o número de células inflamatórias no tecido pulmonar em fase aguda da sepse.
