The Effect of Silymarin on Mesenteric Ischemia-Reperfusion Injury

Objective: To examine the effect of silymarin (SM), a mixture of flavonoids and polyphenols extracted from Silybum marianum, on mesenteric ischemia-reperfusion (I-R) injury in a rat model. Materials and Methods: Fifty rats were randomly divided into 5 groups (n = 10). Group 1 was sham operated, while groups 2-5 were subjected to mesenteric I-R lasting 1 h. Group 2 received isotonic sodium chloride, group 3 received SM (100 mg/kg/day) for 7 days before I-R, group 4 received SM for 7 days after I-R, and group 5 received SM for 7 days both before and after I-R. The rats were sacrificed by exsanguination in groups 1-3 at the 24th hour and groups 4 and 5 were sacrificed on the 7th day of reperfusion. Blood and intestinal specimens were taken for biochemical and pathological evaluations. Results: Serum superoxide dismutase (SOD) and heat shock protein 70 levels were significantly higher in group 2 (5.24 ± 1.76 U/l and 261.4 ± 16.8 ng/ml) compared to the sham group (2.08 ± 1.76 U/l and 189.9 ± 28.7 ng/ml) (p < 0.001 and p < 0.0001, respectively). However, SOD activity and the extent and severity of the histopathological lesions were significantly less in groups 3 [3.11 ± 1.18 U/l, 1.0 (range 0.0-2.0)], 4 [2.15 ± 0.87 U/l, 1.0 (range 1.0-3.0)], and 5 [1.80 ± 0.61 U/l, 0.5 (range 0.0-2.0)], treated with SM, than in group 2 [5.24 ± 1.76 U/l, 2.0 (range 2.0-3.0)] (p = 0.002, p < 0.001, and p = 0.0001; p < 0.001, p = 0.007, and p = 0.0001, respectively). Also, TNF-α levels were lower in the SM-supplemented groups compared to group 2. Serum thiobarbituric acid-reactive substance concentrations were low in the pre-/posttreatment groups treated with SM compared to group 2. No statistical difference was observed for protein carbonyls between the groups. Conclusion: Our findings suggest that SM therapy may attenuate the oxidative and intestinal damage induced by I-R injuries.

Long-term outcomes of intraoperative and perioperative albendazole treatment in hepatic hydatidosis: single center experience

Purpose The aim of this study was to evaluate long-term outcome of the intraoperative and perioperative albendazole (ALB) treatment on the recurrence and/or secondary hydatidosis. Methods One hundred and one patients with hepatic hydatidosis were treated intraoperatively and perioperatively with ALB, in addition to surgery. Perioperative ALB treatment was given in a dose of 12-15 mg/kg/day. The ALB treatment was started 13.27 ± 14.34 days before the surgery, and it was continued for 4.39 ± 3.11 months postoperatively. A total of 1.7 µg/mL of ALB solution was used as a protoscolidal agent. The follow-up period was 134.55 ± 51.56 months. Results Four patients died, with only one death was secondary to hydatid disease (cerebral eccinococcus). There was only one recurrence (1%) of hepatic hydatidosis. Early and late morbidity rates were 8.91% and 7.92%, respectively. Conclusion Our results suggest that intraoperative and perioperative ALB is effective for the prevention of hepatic hydatidosis recurrence and/or secondary hydatidosis.

Changes in the Frequencies of Abdominal Wall Hernias and the Preferences for Their Repair: A Multicenter National Study From Turkey

Abdominal wall hernias are a common problem in the general population. A Western estimate reveals that the lifetime risk of developing a hernia is about 2%.1–3 As a result, hernia repairs likely comprise the most frequent general surgery operations. More than 20 million hernias are estimated to be repaired every year around the world.4 Numerous repair techniques have been described to date however tension-free mesh repairs are widely used today because of their low hernia recurrence rates. Nevertheless, there are some ongoing debates regarding the ideal approach (open or laparoscopic),5,6 the ideal anesthesia (general, local, or regional),7,8 and the ideal mesh (standard polypropylene or newer meshes).9,10

Spleen-preserving laparoscopic distal pancreatectomy: Two cases and review of the technique.

In this study, we aimed to assess the technique and results of spleen-preserving laparoscopic distal pancreatectomy (SPLDP) on the basis of two cases. The first case was a woman with a large cystic papillary lesion of the distal pancreas. The other patient was a woman with a pancreatic mass on the tail of the pancreas. Both patients were operated on using SPLDP. Five trocars were used in the first case and four trocars were used in the second case. Thirty degree telescope visualization and LigaSure dissection were used during the operation. The splenic vessels were dissected, but the short gastric vessels were preserved. The pancreas was transected by one Endo GIA stapler and the cut edge of the pancreas was reinforced with sutures to prevent a pancreatic fistula. We performed the same technique in both cases. However, in the first case, we aspirated the content of the cystic mass of the pancreas before removing it to avoid making a large incision. The duration of the operation was 190 and 135 minutes, respectively. There were no postoperative complications. SPLDP is a safe, effective modality for managing lesions of the distal pancreas. If the splenic vessels are transected, the short gastric vessels must be protected to ensure the viability of the spleen.

Pilonidal sinüs hastalığında ameliyat yöntemlerinin komplikasyon ve hastaların yaşam kalitesine etkisi

GIRIŞ Pilonidal sinus agirlikli olarak calisma cagindaki erkekleri etkileyen sakrokoksigeal bolgenin sik gorulen bir hastaligidir. Hastalik genellikle apse veya kronik akintili olan bir sinus trakti ile kendini gosterir. Sikligi bolgesel ve irksal olarak degismektedir. Etyoloji ve patogenezi yillardir tartisilmaktadir. Pilonidal sinus hastaliginin tedavisi icin bircok medikal ve cerrahi yontem tarif edilmesine karsin tartismalar devam etmektedir. Pilonidal sinuste uygulanacak ideal tedavi az agrili, hastanede kalis suresi kisa, dusuk komplikasyon riski, hastanin normal aktivitesine hizli donmesini saglayan ve dusuk nuks orani olan bir yontem olmalidir (1-3). Eksizyon sonrasi primer onarimda ameliyatin kisa surmesi, hastanede kalis suresinin kisa olmasi gibi avantajlari olmasina karsin flep yontemlerinde orta hattin lateralize olmasi nedeniyle nuks oranlarinin daha dusuk olmasi beklenmektedir.
