ABSTRACT: Among appendicitis patients pregnant ones occupy only a small proportion. Still there are difficulties in the diagnosis and management of the acute appendicitis in pregnant population. We tried to find answers to these difficulties with our acute appendicitis cases in pregnant patients.
This study involved 46 pregnant patients who received an operation following diagnosis of acute appendicitis in our clinic from 2006 to 2009. Data were collected retrospectively from medical records. Age, time delay to diagnosis, leukocyte count (WBC), gestational age, gestational history, morbidity-mortality and pathology results were evaluated.
The mean age of patients, gestational age and number of prior pregnancies were 26, 21 and 2.6, respectively. The amount of time spent in the hospital, from presentation of first symptom to admission, was approximately 40 hours (range 6-120). The mean time from admission to operation was 5.89 (range 1-32) hours. The perforation rate among our cases was 21%. The negative appendectomy rate was 13%. The perforation rate was associated with advanced gestational age and delayed admission to the hospital (p ≤ 0.001 and p = 0.027, respectively).
The diagnosis of appendicitis in pregnancy is difficult, and the perforation rate is high. Particularly in term pregnancies, we recommend performing appendectomy immediately after cesarean section.

ABSTRACT: The aim of this study was to evaluate the effect of internal iliac artery (IIA) ligation performed for severe postpartum hemorrhage (PPH).
Thirty-three women who underwent IIA ligation to control PPH in a tertiary referral center between June 2007 and May 2009 were included in this retrospective analysis. IIA ligation was performed as the primary surgical intervention or to control bleeding following hysterectomy.
The 33 women underwent IIA ligation due to uterine atony (n = 22), placenta previa accreta/increta/percreta (n = 5), uterine rupture (n = 4), and placental abruption (n = 2). Twenty-four women underwent IIA ligation as the primary surgical intervention. IIA ligation resulted in control of bleeding in 18/24 women (75%), and only 6/24 women (25%) showed unsuccessful management of bleeding with IIA ligation. In the six women for whom the bleeding was not controlled with IIA ligation, hysterectomy was urgently performed before closure of the abdomen. After obtaining adequate hemostasis with IIA ligation, no women required relaparotomy in the postoperative period. Nine women with persistent bleeding following hysterectomy were also treated with IIA ligation. In our study, there were no intraoperative or postoperative complications related to the procedure.
IIA ligation may be an effective and safe treatment option to arrest severe PPH. This procedure may also be useful to arrest persistent hemorrhage after hysterectomy. Increased understanding of the retroperitoneal anatomy is needed to reduce the risk of intraoperative and postoperative serious complications.

ABSTRACT: In previous studies, it has been demonstrated that Nigella Sativa (NS) has protective effects against ischemia reperfusion injury on various organs. However, its protective effects on intestinal tissue against ischemia reperfusion injury are unclear. We aimed to determine whether NS prevents intestinal ischemia-reperfusion injury in rats.
Thirty rats were divided into three groups as sham (group 1), control (group 2), and NS-treatment group (group 3). All rats underwent intestinal ischemia for 60 min followed by a 60-min period of reperfusion. Rats were intraperitoneally infused only 0.9% saline solutions in group 2. Rats in the group 3 received NS (0,2 mL/kg) intraperitoneally, before ischemia and before reperfusion. Total antioxidant capacity (TAC), catalase (CAT), total oxidative status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO) in ileum tissue were measured. Also, ileum tissue histopathology was evaluated by a light microscope.
The levels of liver enzymes in group 3 were significantly lower than those in group 2 (p <.01). TAC and CAT activity levels in ileum tissue were significantly higher in group 3 than in group 2. TOS, OSI, and MPO in ileum tissue were significantly lower in group 3 than group 2 (p <.05 for TOS and MPO; p < .01 for OSI). Histological tissue damage was milder in the NS treatment group than in the control group.
Our results suggest that NS treatment protected the rat's intestinal tissue against intestinal ischemia-reperfusion injury.

ABSTRACT: In this study we examined the effect of oral application of garlic form [garlic oil (GO)] on rats after renal ischemia-reperfusion (I/R) injury.
Forty male Wistar albino rats were divided into four groups: control, sham-operated, I/R, and I/R+GO. GO was diluted in water and administered by oral intubation three times each week for 6 weeks. All rats except sham-operated underwent 45 min of bilateral renal ischemia followed by 6 hr of reperfusion. Blood samples and kidney tissues were harvested from the rats, and then rats were killed. Serum urea, creatinine, and cystatin C levels were determined. Total antioxidant capacity (TAC), catalase (CAT), total oxidant status (TOS), oxidative stress index (OSI), myeloperoxidase (MPO), nitrite oxide (NO), and protein carbonyl (PC) levels in kidney tissue and blood were measured. In addition, kidney tissue histopathology was evaluated.
The serum urea, creatinine, and cystatin C levels were significantly higher in I/R group compared to I/R+GO group (p<0.01). The serum and tissue antioxidant markers (TAC, CAT) were significantly lower in I/R group than I/R+GO group (p<0.01). The serum oxidant markers (TOS, MPO, NO, and PC) were significantly higher in I/R group than I/R+GO group (p<0.01). Also oral application of GO was effective in decreasing of tubular necrosis score.
Based on the present data, we conclude that increased antioxidants and decreased oxidants modulated by oral application of GO attenuated the renal I/R injury.

ABSTRACT: We investigated the synergistic effect of hyperbaric oxygen (HBO) and granulocyte-colony stimulating factor (G-CSF) on adhesion formation in rats.
40 adult male Sprague-Dawley rats (250-350 g) were divided into 4 groups. In group-1, no further management was undertaken. Group-2 received HBO therapy, group-3 was treated with 50 ug/kg subcutaneous G-CSF once daily for 7 days following laparatomy and cecal abrasion and group-4 was given both G-CSF and HBO therapies. On the 7th day, all rats were sacrificed and adhesions were scored. Tissue samples from adhesions and peritonea and cecum wall were examined both pathologically and biochemically for tissue hydroxyproline content.
No mortality occurred in study groups. When the groups were evaluated according to the adhesion numbers and grades, there was a statistically significant difference between the control and groups 3 and 4 (P < 0.001). There was no statistically significant difference between groups 1 and 2 (p > 0.05). HBO + G-CSF group was significantly different from control, HBO and G-CSF groups, regarding hydroxyproline contents (p = 0.005). Inflammation and fibrosis did not differ significantly among the groups (p = 0.248), (p = 0.213).
HBO treatment could not reduce the adhesion formation alone. Combined use of HBO and G-CSF, has a markedly preventive effect on postoperative adhesion formation (Tab. 1, Fig. 2, Ref. 57).

ABSTRACT: Ischemia-reperfusion, commonly seen in the fields of trauma surgery and renal transplantation, is a major cause of acute kidney injury and is associated with significant morbidity and mortality. The protective effects of Nigella sativa against ischemia-perfusion damage to various organs have been previously documented. However, its protective effects on kidney tissue against ischemia-reperfusion injury are unclear. In this study, we aimed to examine the effect of Nigella sativa in modulating inflammation and apoptosis after renal I/R injury.
Thirty male Wistar-albino rats were divided into three groups: sham-operated, ischemia-reperfusion, and ischemia-reperfusion + Nigella sativa. Rats in the third group were given Nigella sativa 6 h prior to ischemia-reperfusion and at the beginning of reperfusion. All rats except those in the sham-operated group underwent 45 min of bilateral renal ischemia followed by 45 min of reperfusion. Blood samples and liver tissues were harvested from the rats, and then rats were sacrificed. Serum urea and creatinine levels were determined. Total antioxidant capacity (TAC), catalase (CAT), total oxidant status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO) in kidney tissue and blood were measured. Kidney tissue histopathology was also evaluated. Results. Nigella sativa was effective in reducing serum urea and creatinine levels as well as decreasing the tubular necrosis score. Nigella sativa treatment significantly reduced OSI and TOS levels and increased TAC levels in both kidney tissue and blood.
The observed differences seem to demonstrate the protective effect of Nigella sativa against renal I/R injury in rat kidneys.

ABSTRACT: Nigella sativa (NS) has been shown to have antioxidant and antiinflammatory activities in different conditions. The goal of this study was to evaluate the effects of NS on cholestatic liver injury in rats. Thirty rats were recruited in the study as follows: Group 1, Bile duct ligation (BDL) (n = 10); Group 2, BDL plus NS (n = 10); and Group 3, Sham (n = 10). Bile duct ligated group received 0.2 mL kg(-1) dose of NS intraperitoneally daily throughout 14 days. Liver damage and cholestasis were determined by the biochemical and the pathologic examination. Data showed a decrease in gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) activities of the NS treated rats when compared with BDL group (p < 0.001 for GGT and p < 0.05 for others). The NS treated rats' tissue levels of total oxidant status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO) were significantly lower than that of the BDL group (p < 0.01 for all). Increases in total antioxidant capacity (TAC) and catalase (CAT) levels were statistically significant in the NS treated rats compared to BDL group (p < 0.01 for both). On the other hand, administration of NS in the rats with biliary obstruction resulted in inhibition of necro-inflammation. These results indicate that NS exerts a therapeutic effect on cholestatic liver injury in bile duct ligated rats possibly through attenuation of enhanced neutrophil infiltration and oxidative stress in the liver tissue.

ABSTRACT: Flavonoids have been subjected to considerable investigations due to their antioxidant and anti-inflammatory properties. Yet the effects of flavonoids on the ileum and spleen against hepatic ischemia-reperfusion injury have so far not been addressed.
We aimed to investigate whether micronized purified flavonoid fraction (MPFF) protects the ileum and spleen against hepatic ischemia-reperfusion injury.
Rats were subjected to hepatic ischemia by clamping the hilar area of the rats for 60 min, followed by 60 min of reperfusion. Rats in the treatment group were treated with MPFF (80 mg/kg/day) by gavage for 3 days before surgery, 30 min prior to ischemia and just before the reperfusion. After the reperfusion period, all rats were sacrificed. Ileal and splenic tissues were taken for histological evaluation and determination of the total antioxidant capacity (TAC), catalase, total oxidant status (TOS), oxidative stress index (OSI) and myeloperoxidase (MPO) levels.
TAC levels in the splenic tissue and intestinal tissue were significantly higher in the treatment group than in the control group (P < 0.01 for both). TOS, OSI, and MPO in splenic tissue (P < 0.01, P < 0.05, and P < 0.05, respectively) and intestinal tissue (P < 0.01, P < 0.01, and P < 0.001, respectively) were significantly lower in the treatment group than in the control group. Histological tissue damage of intestinal tissue was milder in the treatment group than in the control group.
The results of this study indicated that MPFF pretreatment significantly limited the injury to the small intestine and spleen induced by hepatic ischemia-reperfusion in rats.

ABSTRACT: The prevalence of sexual dysfunction is high among women; however, sexual dysfunction secondary to anatomical deformity in women is rare. In addition, primary retroperitoneal leiomyomas are very rare clinical conditions.
To present a case with sexual dysfunction secondary to anatomical deformity.
In this article, we report the case of a large retroperitoneal leiomyoma causing sexual dysfunction.
After the surgical removal of the large retroperitoneal mass, previous intercourse difficulties had been resolved.
Retroperitoneal tumors may obstruct the vagina by congesting the pelvic area and may be considered as a possible cause of female sexual dysfunction.

ABSTRACT: The aim of this study was to determine whether resveratrol could prevent intestinal tissue injury induced by ischemia-reperfusion (I/R).
Intestinal I/R was induced in rats' intestines by 60-min occlusion of the superior mesenteric artery, followed by a 60-min reperfusion. Thirty rats were divided into three groups as follows: sham (group 1), control (group 2), and the treatment groups (group 3). The rats in the treatment group received resveratrol both before ischemia and before reperfusion. In all groups, serum aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase levels were determined. Total antioxidant capacity (TAC), catalase, total oxidative status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO) in the intestinal tissue were measured. Intestinal tissue histopathology was also evaluated by light microscopy.
The levels of liver enzymes in group 3 were significantly lower than those in group 2 (P < 0.05). TAC in the intestinal tissue was significantly higher in group 3 than in group 2 (P < 0.05). TOS, OSI, and MPO in the intestinal tissue were significantly lower in group 3 than in group 2 (P < 0.05 for all). Histological tissue damage was milder in the resveratrol treatment group than in the control group.
The results of this study indicated that resveratrol treatment limits the oxidative injury of the small intestine induced by I/R in rats. However, more precise investigations are required to evaluate the antioxidative effect of resveratrol on small intestine tissue damage in clinical and experimental models.

ABSTRACT: To compare 2 laparoscopic appendectomy techniques.
We describe a modified technique, the handmade endoloop technique, for closing the base of the appendix. This prospective study was carried out at Harran University Medical Faculty, Sanliurfa, and Gulhane Military Medical Academy, Ankara, Turkey from September 2006 to February 2008. We evaluated the safety and efficacy of the procedure in 98 acute appendicitis cases: 57 patients handmade endoloop patients, and 41 endoloop technique patients. Operative time, postoperative complications, need for analgesics, and procedure cost were measured for both groups. The endoloops and sutures used to manage appendectomy were listed at current prices, summarized as number consumed per case, and compared. Data were analyzed by appropriate test.
The average price of material used for closing the base of appendix was 81 American Dollars (USD) for laparoscopic appendectomy with endoloop, and 8 USD for the technique described by this article. Overall, postoperative complications, operative time, and the need for analgesia did not show a statistical difference in comparing both groups.
This procedure is simple, safe, and cheap.

ABSTRACT: Caffeic acid phenethyl ester (CAPE) has been subjected to considerable investigations that have revealed its antioxidant and anti-inflammatory activities in different conditions. But there is not a previous investigation about its effect on cholestatic liver injury. The aim of this study was to investigate the effect of CAPE in rat liver against cholestatic liver injury induced by bile duct ligation.
Swiss-albino rats were recruited in the study as follows; Group 1 rats subjected to simple laparotomy known as the sham group; Group 2 rats subjected to bile duct ligation (BDL); Group 3 bile duct ligated rats treated with CAPE. The third group received CAPE (10 micromol/kg) intraperitoneally daily throughout 14 d.
Data showed a decrease in gamma glutamyl transferase (GGT), aspartate aminotransferase (AST), and alanine aminotransferase levels (ALT) of the CAPE treated rats, compared with BDL group (P < 0.001, P < 0.01, and P < 0.02, respectively). In the CAPE treated rats, tissue levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were significantly lower than that of the BDL group (P < 0.001). The levels of glutathione (GSH) in CAPE treated rats were significantly higher than that of BDL group (P < 0.001). In CAPE treated group, the levels of interleukin-1alpha (IL-1alpha) and interleukin-6 (IL-6) were significantly lower than that of BDL group (P < 0.03, P < 0.02, respectively). Administration of CAPE in the rats with biliary obstruction resulted in inhibition of necro-inflammation.
These results suggest that treatment of CAPE maintains antioxidant defenses, reduces oxidative liver injury, cytokine damage, and necro-inflammation in bile duct ligated rats. Thus, CAPE seems to be a promising agent for the attenuation of cholestatic liver injury.

ABSTRACT: To evaluate the efficacy of resection and primary anastomosis (RPA) and RPA with modified blow-hole colostomy for sigmoid volvulus.
From March 2000 to September 2007, 77 patients with acute sigmoid volvulus were treated. A total of 47 patients underwent RPA or RPA with modified blow-hole colostomy. Twenty-five patients received RPA (Group A), and the remaining 22 patients had RPA with modified blow-hole colostomy (Group B). The clinical course and postoperative complications of the two groups were compared.
The mean hospital stay, wound infection and mortality did not differ significantly between the groups. Superficial wound infection rate was higher in group A (32% vs 9.1%). Anastomotic leakage was observed only in group A, with a rate of 6.3%. The difference was numerically impressive but was statistically not significant.
RPA with modified blow-hole colostomy provides satisfactory results. It is easy to perform and may become a method of choice in patients with sigmoid volvulus. Further studies are required to further establish its role in the treatment of sigmoid volvulus.

ABSTRACT: The aim of this study was to investigate the time-dependent relation between plasma D-dimer levels and the degree of intestinal necrosis and to compare these parameters with leukocyte counts in an experimental etrangulated hernia model in rats.
When the duration of intestinal ischemia was prolonged, serum D-dimer levels increased relative to the control group, with the difference being statistically significant at hour 2 (P = 0.027). In contrast, leukocyte counts in the 2- and 4-h strangulation group were higher that those of the control group, but the difference was not statistically significant (P = 0.625 and P = 0.846, respectively). However, in the 6-h strangulation group the levels of leukocytes were significantly higher that those of the control group (P = 0.015).
Serum D-dimer measurements may be used as a more valuable diagnostic parameter than leukocyte count in the early diagnosis of intestinal ischemia, including strangulated hernia.

ABSTRACT: This study was designed to compare the results of the Modified Darn Repair through Lichtenstein procedure in inguinal hernias.
The study involved 322 patients with inguinal hernia, operated in General Surgery Departments of Gulhane Military Medical Academy and Sirnak Military Hospital between 1998 and 2004. The durations of operation time, hospitalization, and time to return to daily activities and postoperative complication and recurrence rates were evaluated. Lichtenstein procedure was applied on 170 patients (Group 1), and modified darn repair was applied on 152 patients (Group 2).
The average follow-up period was 56 months. For the Lichtenstein procedure, the average duration of operation was 56 min; the average time to return to routine activities was 20 days. The number of patients with postoperative complications was 20 (11.7%), and the number of patients with recurrence was 1 (0.6%). For modified darn repair, the average duration of operation was 48 min; the time to return to daily activities was 20 days. The number of patients with postoperative complication was three (1.9%), and no recurrences were noted. The hospitalization time of the groups was similar.
Modified darn repair is a reliable method for inguinal hernia repair with short hospitalization time, low rate of postoperative complications, and recurrence.

ABSTRACT: Objectives: This study was planned to evaluate wheth-er possible changes in the hematological parameters and the biochemical markers can be used to detect obstruction-induced (strangulated) intestinal ischemia. Materials and Methods: Forty rats divided into five groups underwent the following procedures: Group 1 rats were treated with only laparotomy (sham-operated con-trols). To the strangulated hernia groups surgical induc-tion of strangulated intestinal obstruction was performed. Tissue and blood samples were taken at 30 minutes (group 2), 2nd hour (group 3), 4th hour (group 4) and 6th hour (group 5) respectively, and then LDH, CPK, ALP, AST, ALT, D-dimer levels and blood cells counts were measured and histopathological examination was done. Results: Focal mucosal necrosis accompanied was con-firmed by histological findings in the strangulated intestinal ischemia group after second hour. Serum D-dimer, ALT, ALP, CPK levels and neutrophil count became elevated at second hour, which was statistically significant. Conclusion: In patients with hernia, after reduction of the intestinal hernia, raised levels of serum D-dimer, ALT, ALP, CPK levels and neutrophil count may indicate the pres-ence of a bowel ischemia. However, more comprehen-sive clinical studies are required to evaluate the potential survival benefit by using the laboratory tests as a marker and/or a useful diagnostic tool of the need for laparotomy.
