Assessment of the effect of calcium dobesilate in experimental liver ischemia-reperfusion injury.

BACKGROUND: This study investigates the protective effect of calcium dobesilate (CaDob), an effective antioxidant and anti-inflammatory drug, on experimental liver ischemia-reperfusion injury (IRI). METHODS: Forty rats were divided into four groups. In Group 1, (sham), only hepatic pedicle was induced. In Group 2 (control), hepatic pedicle was reperfused for 90 min after being clamped for 60 min. No treatment was given in Group 1 and 2. In Group 3 (perioperative CaDob), 100 mg/kg CaDob was given 2 hours prior to the operation in which hepatic pedicle was reperfused for 90 min following a 60-min clamp. In Group 4 (preoperative CaDob), after 100 mg/kg/day CaDob was given for 10 days before the operation, hepatic pedicle was clamped for 60 min and reperfused for 90 minutes. At the end of these procedures, blood and liver tissue samples were collected for biochemical and histopathological assessment. RESULTS: Liver function tests and tissue oxidative stress parameters were significantly lower in the preoperative and perioperative treatment groups than the control group. Furthermore, it was observed that histopathological injury in the control group significantly decreased in both perioperative and preoperative treatment groups. CONCLUSION: Calcium dobesilate demonstrated a significant hepatoprotective effect in terms of its antioxidant and anti-inflammatory effects.

Use of fibrin glue in preventing pseudorecurrence after laparoscopic total extraperitoneal repair of large indirect inguinal hernia.

PURPOSE: Seroma is among the most common complications of laparoscopic total extraperitoneal (TEP) for especially large indirect inguinal hernia, and may be regarded as a recurrence by some patients. A potential area localized behind the mesh and extending from the inguinal cord into the scrotum may be one of the major etiological factors of this complication. Our aim is to describe a novel technique in preventing pseudorecurrence by using fibrin sealant to close that potential dead space. METHODS: Forty male patients who underwent laparoscopic TEP for indirect inguinal hernia with at least 100-mL volume were included in this prospective clinical study. While fibrin sealant was used to close the potential dead space in the study group, nothing was used in the control group. The volume of postoperative fluid collection on ultrasound was compared between the groups. RESULTS: Patient characteristics and the volumes of hernia sac were similar between the 2 groups. The mean volume of postoperative fluid collection was found as 120.2 mL in the control group and 53.7 mL in the study group, indicating a statistical significance (P < 0.001). CONCLUSION: Minimizing the potential dead space with a fibrin sealant can reduce the amount of postoperative fluid collection, namely the incidence of pseudorecurrence.
