Effect of Intraperitoneal Thymoquinone on Postoperative Peritoneal Adhesions.

BACKGROUND: To determine the effect of thymoquinone on adhesion formation in a rat caecotomy/suture model. MATERIAL AND METHODS: Thirty wistar rats were randomized into three groups: The control group received saline and the thymoquinone group received 10 mg/kg thymoquinone after cecal caecotomy/suture model. In the sham group the abdominal wall was closed without any abrasion to the cecum. On day 15, adhesions were classified, and histopathological samples were taken. RESULTS: There were no incisional hernias or wound dehiscences. In comparing adhesion scores, a significant difference was found between the thymoquinone and the control groups (p < 0.05). The grade of inflammation for the thymoquinone and the sham groups were significantly lower than that of the control group (p < 0.01 and p < 0.001, respectively). Hydroxyproline levels were significantly lower in the sham and thymoquinone groups compared to the control group (p < 0.05). CONCLUSIONS: Based on the results of this study in a rat peritoneal adhesion model, intraperitoneal administered thymoquinone has a strong anti-adhesive effect.

Sigmoid colon torsion: mortality and relevant risk factors.

INTRODUCTION: Sigmoid volvulus is an important acute intestinal obstruction, leading to high mortality and requiring urgent operation. The purpose of this study is to analyze risk factors for mortality in patients that were operated on due to sigmoid volvulus at our Department. MATERIALS AND METHODS: The retrospective study included 158 patients, who were operated on due to sigmoid volvulus between January 1994-December 2010, in terms of age, gender, complaints at admission, physical signs, period of symptoms before admission, associated diseases, laboratory and radiological parameters, hospital stay, morbidity, and mortality. RESULTS: The study consisted of 135 men (85.4%) and 23 women (14.6%), with a mean age of 62.54 years. Cardiovascular disease and respiratory disease were present in 34 (21.5%) and 42 (26.6%) patients, respectively. Urgent operation was undertaken in 125, while 33 received elective surgery. Abdominal distension and pain was evident in all the patients. Generalized tenderness was detected in 58.2%, while 70.9% had hyperactive bowel sound with tympanism. Plain radiograph revealed an impression of "omega ans" in all patients, while free air was detected in 11.4% of them. Risk factors for mortality included age (p = 0.008), delayed admission (p = 0.001), cardiovascular and respiratory diseases (p = 0.001), fluid-electrolyte imbalance (p =0.001), presence of necrosis (p = 0.001), and major contamination (p = 0.001). Wound infection and intraabdominal abscess were more common in patients that developed mortality (p = 0.001 and p = 0.002). CONCLUSIONS: Complications like wound infection and intraabdominal abscess are more frequent in the patients with the risk of mortality. Delayed admission results in higher risk of mortality. Mortality rates can be reduced by early admission, preoperative intensive resuscitation, suitable antibiotics, and emergent and viable surgery.  

The effect of different suture materials on the safety of colon anastomosis in an experimental peritonitis model.

BACKGROUND: The aim of this experimental study was to compare the safety of different suture materials in a left colonic anastomosis in the presence of peritonitis. MATERIALS AND METHODS: Twenty-one male Wistar albino rats were randomly divided into three groups. First, left colonic injuries were created in all groups for the peritonitis model. After 24 hours, coated polyglactin 910 and silk suture were used in Group I rats, polydioxanone and silk suture were used in Group II rats, and coated polyglactin 910 plus antibacterial suture and silk suture were used in Group III rats during colonic anastomosis. Tissue hydroxyproline, anastomotic bursting pressure, and histopathologic findings on the anastomosis line were evaluated on the 10th postoperative day by performing a relaparatomy. RESULTS: The mean bursting pressure values were 198 ± 11.37, 220 ± 17.7, and 244 ± 9.52 in Groups I, II, and III, respectively (Group I vs. II, p < 0.035; I vs III, p < 0.002; and II vs III, p < 0.021). The mean hydroxyproline levels were 1.21 ± 0.58, 1.47 ± 0.44, and 2.11 ± 0.32 in Groups I, II, and III, respectively (Group I vs II, p < 0.338; I vs III, p < 0.011; and II vs III, p < 0.025). When histopathologic findings of the groups were compared, the healing score of the intestinal tissue was higher in Group III than in Group I (p < 0.015), whereas there were no statistically significant differences among Groups I vs II and II vs III (p < 0.081 and p < 0.095, respectively). CONCLUSION: Antibacterial suture usage increased anastomosis safety in the presence of peritonitis in resection and primary anastomosis.

Blunt trauma - related isolated pancreatic injury.

BACKGROUND: Pancreatic injuries arising from blunt trauma are rarely seen. Diagnosis and treatment are difficult because of retroperitoneal localization of the organ. We present four pancreatic cases with isolated pancreatic injury due to blunt abdominal trauma. METHODS: This retrospective study included four pancreatic patients who were operated on due to isolated injury caused by blunt abdominal trauma at our department between January 2004 and October 2010. RESULTS: The patients consisted of three males and one female. One of them was in stage IV and the rest were in stage III. All underwent pancreaticojejunostomy, distal pancreatectomy, distal pancreatectomy + splenectomy and drainage, respectively. Fistula developed in two of them, and abscess developed in one, while the other one died. CONCLUSION: Diagnosis may be delayed since the clinical condition is initially stable. Tomography remains one of the most important diagnostic tools. Common risk factors for morbidity and mortality are the presence of ductal injury and delayed laparotomy (Tab. 1, Fig. 4, Ref. 22).

Laparoscopic salvage for malfunctioning of peritoneal dialysis catheters.

AIM: The aim of this study was to emphasize the efficacy of the laparoscopic surgical method performed for elimination of catheter-induced mechanical complications developing in CAPD patients. METHODS: Medical records of 31 patients who had undergone CAPD catheter implantation at the Dicle University Medical Faculty Hemodialysis Unit between January 2001 and June 2012 were examined retrospectively. Double-felted spiral Tenckhoff catheters were used in all patients for peritoneal access. RESULTS: We performed a retrospective review of 31 patients who, over an 11-year period, underwent revision of a peritoneal dialysis catheter using laparoscopy. Chronic renal failure requiring dialysis occurred in 31 patients (12 males and 19 female). Ages ranged from 13 to 77 years (mean age 35.8 years). CONCLUSION: As a conclusion, CAPD is currently a choice to be frequently used in patients with ESRD. In the treatment of CAPD-associated mechanical catheter complications laparoscopic method may be preferred because of patient comfort, short hospital stay, and lesser postoperative complications.

The protective effects of pomegranate on liver and remote organs caused by experimental obstructive jaundice model.

OBJECTIVE: We aimed to investigate the protective potential of pomegranate extract on the liver and remote organs in rats with obstructive jaundice. MATERIALS AND METHODS: The rats were split into 4 groups. In Group 1 (G1) (sham group) rats, the common bile duct was mobilized without any ligation. Group 2 (G2) received a combination of the sham operation and synchronous treatment with pomegranate. Group 3 (G3) received common bile duct ligation (CBDL). Group 4 (G4) were subjected to CBDL and treatment with pomegranate. After 8 days, we measured total oxidative status (TOS) and antioxidant capacity in the rats' liver tissue and remote organs, and evaluated blood levels of malondialdehyde and total antioxidant capacity (TAC). RESULTS: G3 rats showed significantly raised malondialdehyde level as compared to G1 rats (p < 0.001). Following the pomegranate therapy, a decrease in malondialdehyde was observed (p = 0.015). TAC levels were significantly raised in the G3 rats compared to the G1 rats (p = 0.004). TAC levels dropped after pomegranate therapy (p = 0.011). CBDL caused elevated TOS levels in the liver and remote organs, with a statistically significant increase in the lung tissue (p = 0.002). TOS levels in the CBDL groups decreased after pomegranate treatment (p < 0.001). CONCLUSIONS: This study reveals the marked protective effect of pomegranate on the liver and remote organs in obstructive jaundice.

Factors affecting morbidity and mortality in hollow visceral injuries following blunt abdominal trauma.

BACKGROUND AND AIM: Hollow visceral injuries following blunt abdominal trauma are uncommon. The potential risk factors affecting morbidity and mortality are not well known. The purpose of our study was to evaluate the outcomes of hollow viscus perforation after blunt abdominal trauma. MATERIALS AND METHODS: Patient files of 56 adult patients who were treated with diagnosis hollow viscus injuries due to blunt abdominal trauma between the years 2000 and 2011 at the Dicle University Medical School General Surgery Clinic were retrospectively evaluated by analyzing the relationship between morbidity-mortality and potential risk factors. RESULTS: Fifty-six patients formed the study group, with median age of 37.5 ± 17,0 (range, 16-78) years and a significant male (80.3%) predominance. The median Injury Severity Score was 4 (1-25). The median length of hospital stay 7.5 (1-21) days. The mean age in the group with morbidity (47.1 ± 17.4) was significantly higher than the group without morbidity (34.3 ± 15.8) (p<0.05). Also, re-operation (p=0.0013), treatment modality (p=0.037), cause of injuries (0.0046) were other factors that affect morbidity. CONCLUSIONS: These findings suggest that factors affecting morbidity were cause of injuries, re-operation and treatment in patients with hollow viscus injury caused by blunt abdominal trauma. And factors affecting mortality were the injured organ, the presence of shock and median injury severity score.

Rectovaginal fistulas: five year's experience.

BACKGROUND: Rectovaginal fistula is an epithelial connection between the anterior wall of the rectum and posterior wall of the vagina. The etiology of the rectovaginal fistula can be trauma orginated from violent acts or foreign bodies as well as trauma during obstetric, gynecologic, or colorectal surgeries. The purpose of this study was to share our clinic experience and surgical management for rectovaginal fistulas. PATIENTS AND METHODS: This study was conducted at the Department of General Surgery, University of Dicle. All patients who were treated for rectovaginal fistulas between January 2005 and December 2011 were included to this study. RESULTS: There were fifteen patients in a mean age of 32 ± 9.6. The most common complains of patients were arrival of gas and stool from the vagina. The etilogy of rectovaginal fistula was most commonly obstetric trauma in our patients and three of them had anal incontinance. The mean time of hospital stay was 5 days ± 1.7. Postoperative wound infection was seen in two patients and reccurence disease occurred in two patients during the postoperative period. CONCLUSIONS: Rectovaginal fistula treatment is a challenging condition for the surgeon since anatomical relationships and different surgical conditions changes according to the paitents. Various surgical techniques are available for the management of rectovaginal fistulas according to their etiology, size, location. For the treatment of low fistulas, best results were achieved using conservative fistulectomy, layer closure, and both-sided covering of the tissue defect with advancement vaginal and rectal flaps.

The comparison of the effects of hot milk and hot water scald burns and factors effective for morbidity and mortality in preschool children.

PURPOSE: Scald burns are the leading cause of burns in children, especially in those younger than 5 years of age, however, they are easily preventable. Our aim in this study was to emphasise the importance and impact of scald burns caused by hot milk. METHODS: A total of 334 patients below seven years of age were included in this study. Of these, 252 were admitted with acquired hot water scald burns (Group 1) and 82 with hot milk scald burns (Group 2) between August 2009 and September 2010. Demographic data of the patients were retrospectively investigated. RESULTS: The depth of the burns was determined to be higher in Group 2 (p < 0.001). The total burnt body surface area in Group 1 and Group 2 were 17.1 ± 12.3 and 16.3 ± 10.9 (p = 0.99), respectively. Skin grafting was performed in 23 patients in Group 1 and 16 patients in Group 2 (p = 0.01) and complications developed in three patients in Group 1 and in five patients in Group 2 (p = 0.01). The mean length of hospital stay was 9.1 ± 7.4 days in Group 1 and 14.9 ± 9.8 days in Group 2 (p < 0.001) and the mortality rates were similar between the two groups. CONCLUSIONS: More emphasis should be placed on the effects of hot milk scalding due to its ominous clinical course and the high healthcare costs associated with this type of scalding. We believe that taking simple precautions would help reduce the physical, psychological effects and financial consequences of hot milk scalds.

Sigmoid volvulus treated by resection and primary anastomosis: urgent and elective conditions as risk factors for postoperative morbidity and mortality.

PURPOSE: Sigmoid volvulus is a major cause of intestinal obstruction. The aim of this study is to analyze urgent and elective conditions as risk factors for morbidity and mortality regarding sigmoid colon resection and primary anastomosis in patients with sigmoid volvulus. METHODS: This retrospective study included 63 patients diagnosed with sigmoid volvulus, who underwent sigmoid colon resection plus primary anastomosis under urgent or elective conditions between January 1994 and December 2010. RESULTS: Sigmoid colon resection plus anastomosis was performed in 63 patients; 31 (49.2 %) under urgent conditions, while 32 (50.8 %) were performed electively. The mean age of the patients was 65.2 ± 15.2 (18-95) years. The patients consisted of 50 (79.4 %) men and 13 (20.6 %) women. There were no statistical significances between groups in terms of age, gender, associated diseases, and hospital stay. Postoperative morbidity occurred in 30.2 % of patients. The morbidity rates for the urgent group and the elective group were 35.5 and 25.0 %, respectively (p = 0.419). Wound infection, pneumonia, and evisceration were the most common postoperative complications. Wound infection was higher in the urgent group (p = 0.026). In terms of other complications, the groups were similar. Total mortality occurred in 19.4 % of the urgent group and 15.6 % of the elective group (p = 0.750). CONCLUSION: Sigmoid colon resection plus primary anastomosis-related morbidity and mortality rates were similar in patients who were operated on under urgent and elective conditions, and who maintained good general condition.

Splenic injuries: factors affecting the outcome of non-operative management.

PURPOSE: The aim of this study was to evaluate the outcome of non-operative management (NOM) in patients with splenic injuries and to determine the predictive factors of NOM failure. METHODS: Two hundred and six patients with splenic injury were admitted between January 2005 and April 2011. Of the 206 patients with splenic injury, 47 patients met the inclusion criteria of NOM. The mechanism of injury, grade of splenic injury, other intra- and extra-abdominal injuries, systolic blood pressure on admission, hemoglobin levels, number of transfusions, Injury Severity Score (ISS), Glasgow Coma Scale score, and hospitalization period were recorded. The patients were divided into two groups: those with NOM and those in whom the failure of NOM led to laparotomy. The patients were monitored for vital signs, abdominal findings, and laboratory data. NOM was abandoned in cases of hemodynamic instability, ongoing bleeding, or development of peritonitis. Independent predictive factors of NOM failure were identified. The patients managed non-operatively were compared with the patients for whom NOM failed. RESULTS: NOM was successful in 40 of 47 patients. There were differences between the two groups for ISS, hemoglobin levels, need for blood transfusion, and the number of associated extra-abdominal injuries. The grade of splenic injury was determined to be an important and significant independent predictive factor for the success of NOM of splenic injuries. CONCLUSIONS: The grade of splenic injury is an important and significant independent predictor factor for the success of NOM. NOM is not recommended in patients with high-grade splenic injury.
