LIVER RETRACTION USING ELASTIC BANDS

The aim of this study was to investigate whether accommodating elastic bands with barbell back squats (BSQ) increase muscular force during the deceleration subphase. Ten healthy men (mean ± standard deviation: Age: 23 ± 2 years; height: 170.5 ± 3.7 cm; mass: 66.7 ± 5.4 kg; and BSQ one repetition maximum (RM): 105 ± 23.1 kg; BSQ 1RM/body mass: 1.6 ± 0.3) were recruited for this study. The subjects performed band-resisted parallel BSQ (accommodating elastic bands each sides of barbell) with five band conditions in random order. The duration of the deceleration subphase, mean mechanical power, and the force and velocity during the acceleration and deceleration subphases were calculated. BSQ with elastic bands elicited greater mechanical power output, velocity, and force during the deceleration subphase, in contrast to that elicited with traditional free weight (p < 0.05). BSQ with elastic bands also elicited greater mechanical power output and velocity during the acceleration subphase. However, the force output during the acceleration subphase using an elastic band was lesser than that using a traditional free weight (p < 0.05). This study suggests that BSQ with elastic band elicit greater power output during the acceleration and deceleration subphases.

Background. In laparoscopic upper-gastrointestinal (GI) surgery, an adequate retraction of the liver is crucial. Especially in single-port surgery and obese patients, problems may occur during liver retraction. The current study seeks to evaluate the efficacy and safety of the LiVac trocar-free liver retractor in laparoscopic upper-GI surgery. Methods. The present study is a nonrandomized dual-center clinical series describing our preliminary results using the LiVac system for liver retraction. The primary end points of the present study included the effectiveness and safety of the LiVac device as well as complications and documentation of problems with the device during surgery. Results. The device was used in 11 patients for simple and complex laparoscopic procedures. The mean age of the study population was 59.6 years (SD = 20.6; range = 30-84). There were 6 female and 5 male patients with a mean body mass index (BMI) of 31.9 kg/m2 (SD = 8.1; range = 26.0-45.3). The efficacy of the device was excellent in all cases, reducing the number of trocars needed. There were no device-related complications. Conclusion. The LiVac liver retractor is easy to use and provides a good exposure of the operative field in upper-GI laparoscopic surgery, even in obese patients with a high BMI.

Context:Imbalance in shoulder-rotator muscles has been considered a risk factor for injuries in handball. Strength training programs (STPs) may play an important preventive role.Objective:To verify the effects of an STP using elastic bands on shoulder muscles and ball-throwing speed.Design:Randomized and prospective controlled trial.Setting:Exercise physiology laboratory.Participants:Thirty-nine female handball players were randomly assigned to an experimental (EG, n = 21, 15.3 ± 1.1 y) or a control (CG, n = 18, 15.0 ± 0.8 y) group.Intervention:The EG performed the STP with elastic-band progressive exercises for 6 wk before regular handball training, and the CG underwent only their regular training.Main Outcome Measures:Before and after the STP, both groups underwent a ball-throwing-speed test and isokinetic test to assess shoulder internal- (IR) and external-rotator muscle performance.Results:Average power values for IR muscles presented a significant group-vs-time interaction effect (F = 3.9, P = .05); EG presented significantly higher values after the STP (P = .03). Ball speed presented higher values in EG after the STP in standing (P = .04) and jumping (P = .03) throws. IR peak-torque values and balance in shoulder-rotator muscles presented no group-vs-time interaction effect.Conclusions:STP using elastic bands performed for 6 wk was effective to improve muscle power and ball speed for young female handball players.

Background. Although liver retraction using n-butyl-2-cyanoacrylate (NBCA) glue has been applied to laparoscopic upper abdominal surgery in noncirrhotic patients, there is still no consensus on its safety and feasibility for cirrhotic patients. In this study, we aimed to investigate the safety and effectiveness of liver retraction using NBCA glue during laparoscopic splenectomy and azygoportal disconnection (LSD) for gastroesophageal varices and hypersplenism secondary to liver cirrhosis and portal hypertension. Methods. Thirty-nine gastroesophageal varices and hypersplenism secondary to liver cirrhosis and portal hypertension patients were included in our study. We performed LSD in the presence of NBCA glue (n = 22, NBCA group) and absence of NBCA glue (n = 17, n-NBCA group), respectively. The operation time, blood loss, postoperative hospitalization, and liver function were compared between the two groups. Results. There was no mortality during the operation. One patient in non-NBCA group received open surgery due to parenchyma hemorrhage. Postoperative pleural effusion occurred in 2 cases of the NBCA group and 1 of the non-NBCA group. One showed left subphrenic abscess in the non-NBCA group. No postoperative bleeding occurred after 9-30 months of follow-up. The time of operation in NBCA group was significantly shorter than those in n-NBCA group (198.86±17.86 versus 217.81±20.25min, P<0.01). Blood loss in NBCA group was significantly lower than non-NBCA group (159.09±56.98 versus 212.50±88.51 ml, P<0.05). The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were increased on day 1 after LSD and decreased to normal level on day 7 after LSD in both groups. There was no significant difference in postoperative hospitalization and liver function between the two groups. Conclusion. Liver retraction using NBCA glue during LSD for gastroesophageal varices and hypersplenism secondary to liver cirrhosis and portal hypertension is safe, effective, and feasible.
