RESUMO

PURPOSE: Polymeric clips (Hem-o-lok ligation system) are now widely used to securing the base of the appendix during laparoscopic appendectomy. Studies comparing the use of single or double hem-o-lok clips are limited. The aim of this study was to compare the reliability of a single hem-o-lok clips with a double hem-o-lok clips for closure of an appendiceal stump. METHODS: This prospective randomized study includes patients from two centers who underwent laparoscopic appendectomy with the diagnosis of appendicitis between September 2020 and March 2023. Demographic, operative and clinical outcomes of the use of single or double hem-o-lok clips for closure of the appendiceal stump were compared. Factors affecting long postoperative hospital stay were investigated using univariate and multivariate analyzes. RESULTS: One hundred forty two (48.3%) patients in the single hem-o-lok arm and 152 (51.7%) patients in the double hem-o-lok arm were included in the analysis.The shortest operative time was noted in the single hem-o-lok group (52.1 ± 19.9 versus 61.6 ± 24.9 min, p < 0.001). The median hospital stay was 1 day (range 1-10) in the single hem-o-lok group and 1 day (range 1-12) in the double hem-o-lok group, and was shorter in the single hem-o-lok arm (1.61 ± 1.56 vs 1.84 ± 1.69, p = 0.019). Based on multivariate analysis, drain placement was identified as an independent predictive factor for long hospital stay. CONCLUSIONS: The use of single hem-o-lok clips for appendiceal stump closure during laparoscopic appendectomy is safe and effective. Trial registration NCT04387370 ( http://www. CLINICALTRIALS: gov ).

RESUMO

Wound healing is a dynamic process initiated in response to injury. There are many factors that have detrimental effects on the wound healing process. Numerous studies have been conducted for improving wound healing processes. Dexpanthenol is widely used to accelerate wound healing. Sucralfate is used for the treatment of peptic ulcers. We aimed to compare the efficacy of topical Dexpanthenol and Sucralfate in an experimental wound model in rats via histopathological examinations and immune histochemical determinations, as well, to evaluate their effects on EGF levels. Three different groups were formed: the Control Group, the Dexpanthenol Group and the Sucralfate Group. Full-thickness skin wounds were created on the back of each rat and isotonic saline was applied to the wounds of the rats in the control group, Bepanthol® cream was applied in Dexpanthenol Group and 10% Sucralfate cream was applied in Sucralfate Group, once a day. On the 7th, 14th and 21st days the wounds were measured and seven rats from each group were sacrificed and the wounds were excised for histopathological examination. Sucralfate increased wound healing rates by increasing neovascularization, fibroblast activation, reepithelialization and collagen density, as well as dexpanthenol. Our study revealed that the dexpanthenol and sucralfate groups were better than the control group in terms of their effects on wound healing, however there was no statistically significant difference among these two groups. Sucralfate improves EGF expression in skin wounds and has positive results on skin wound healing comparable to dexpanthenol.

RESUMO

OBJECTIVES: Various techniques are used in the management of splenic hilum during laparoscopic splenectomy. Among them, the most used ones are polymer clips, en-bloc stapling and ultrasonic devices. To the best of our knowledge, there is no study in the literature comparing the results of clip and stapler techniques. This study was aimed to compare our results of clip ligation and en-bloc stapling of the splenic hilum. MATERIAL AND METHODS: The records of 67 patients undergoing laparoscopic splenectomy between December 2012 and October 2017 were reviewed. Patients were divided into two groups according to surgical method (stapler group: 26 patients and clip group: 41 patients). Patient age, sex, diagnosis, surgical technique, operation time, spleen dimensions, perioperative complications, postoperative hospital stay, blood transfusions, postoperative thrombocyte and hemoglobin levels were recorded. RESULTS: Operating time was median 115 min (75-230) in the stapler group and 120 min (60-210) in the clip group, and there was no significant difference between the groups (p= 0.2593). There were no significant difference between the groups in terms of the postoperative complications (p= 0.59). Postop- erative hospital stay was median 3.5 (2-8) days in the stapler group and 3 (2-6) days in the clip group with no significant difference (p= 0.0733). CONCLUSION: Clip ligation and en-bloc stapling techniques have no superiority over each other. Our results also showed that both techniques are safe and feasible. We suggest opting for the method according to the surgeon's experience and hospital facilities.

RESUMO

PURPOSE: Vascular structures of the liver and the bile ducts are crucial during liver transplantation or liver resection surgery. Here, we report on variations in the vascular structures and bile ducts of 200 patients. MATERIALS AND METHODS: We reviewed magnetic resonance cholangiopancreatographic and multiple-detector computed tomographic data. RESULTS: Michels type 1 was detected in 54% of the patients. The other most common variations were, respectively, Michels type 5 (13%) and type 2 (11%). Unclassified variations were defined as Michels type 11; 5% of patients were in this group. Type 1 variations in the hepatic portal vein were detected in 76% of our study group. Other common variations were type 2 (9%) and type 3 (8.5%). The left and intermediate hepatic veins united to become a single vein and then joined the inferior vena cava in 64% of the patients. The right, intermediate, and left hepatic veins joined the inferior vena cava separately in 36% of the patients. Type A, which represents the classic anatomy of the bile duct, was observed in 51.5% of our patients. Type C1 and type B were detected in 15% and 12% of patients, respectively. CONCLUSIONS: We describe vascular and biliary variations in the livers of our patients.

RESUMO

Background Superior mesenteric artery syndrome (SMAS) results from the compression of the third part of the duodenum between the aorta and the proximal part of the superior mesenteric artery (SMA). Clinical presentation of SMAS is characterized by the dilatation of the proximal part of the third part of the duodenum. SMAS is a rare cause of the upper gastrointestinal system (UGS) obstruction. In this study, we aimed to present our clinical experience in the treatment of five patients with SMAS, which is a rare clinical condition requiring surgery. Patients and methods The retrospective study included five patients who were treated due to SMAS at our clinic between January 2010 and January 2014. Results All the patients were underweight, with a mean BMI of 15.73 (14-16). The clinical symptoms included epigastric pain after food intake, large volume bilious emesis, early satiety, failure to gain weight, indigestion, esophageal reflux, sense of fullness, and persistent weight loss. SMAS was diagnosed using barium meal studies, upper gastrointestinal endoscopy, abdominal ultrasonography, and CT angiography. Four patients underwent duodenojejunostomy and one patient was managed with gastrojejunostomy. No complication was observed during the postoperative period, and all the patients achieved significant improvement in symptoms. Conclusion SMAS is a rare cause of UGS obstruction, and the diagnosis of SMAS is often delayed. SMAS should be suspected in the differential diagnosis of the patients with unsubstantiated symptoms of persistent nausea, emesis, and significant weight loss.

RESUMO

INTRODUCTION: The aim of our study was to determine the effectiveness of immunoglobulin, rituximab and plasmapheresis in renal transplant patients with antibody mediated rejection (AMR). PATIENTS AND METHODS: Fourteen renal transplant patients with AMR were included in this study. The mean age of the patients was 33.9 ± 10.3 years and 10 (71.4%) of them were male. Lymphocyte cross match was negative for all patients and 10 (71.4%) of them were living donor transplants. Six patients were administered tacrolimus, three patients cyclosporine, two patients everolimus, and three patients sirolimus for immunosuppression. The patients with AMR were administered IVIG, rituximab and plasmapheresis. RESULTS: Patient survival rate was 100%, graft survival rate after AMR was 50% in the first year and 33% in the 2nd and third years. AMR developed 31.9 ± 25.9 months after transplantation. Seven (50%) patients lost their grafts. Delayed graft function was observed in 28.6%, chronic allograft dysfunction in 78.5%, diabetes after transplantation in 14.3%, and cytomegalovirus infection in 7.1% of the patients. At the last follow-up, the mean blood creatinine was 3.1 ± 1.4, the mean proteinuria was 2300 (1300-3300) mg/day and the mean GFR was 34.5 ± 17.6 ml/min. C4d was positive in peritubullar capillaries in all patients, while neutrophil accumulation in peritubular and glomerular capillaries was observed in 8 patients. Chronic allograft vasculopathy was observed in 12 patients. CONCLUSION: AMR leads to progressive loss of renal function and has low graft survival. More effective treatment alternatives are needed for this clinical issue.

RESUMO

BACKGROUND: Retained surgical sponge is a term to define forgotten surgical sponges during operation. RSS causes two kinds of reactions in the body. The first one is to develop an abscess through exudative inflammatory reaction in early phases and second one is to form a mass through aseptic inflammatory reaction which can stay asymptomatic for months, even for years. In this study we aimed to investigate the time of hospital admission, type of reaction and effect of need for bowel resection on prognosis in patients with retained surgical sponge. METHODS: In the study, we scanned the files of 18 patients with retained surgical sponge who had been operated at Dicle University Medical Faculty General Surgery Clinic between January 1994 and July 2012, retrospectively. RESULTS: Need for intestine resection was higher in patients who were operated in the early phase (p:0.034). Morbidity and duration of hospital stay were significantly higher (respectively P:0.02, P:0.007) in patients who had underwent intestine resection. CONCLUSION: In patients with retained surgical sponge, need for intestine resection is increased due to exudative reaction in the early phase. This increase is giving rise to morbidity rates and prolonged hospital stay. KEY WORDS: Morbidity, Retained surgical sponge.

RESUMO

INTRODUCTION: Hepatic ischemia/reperfusion injury may occur after large tumor resection and liver transplantation procedures. Nitric oxide was shown to have protective effects on ischemia/reperfusion injury. Nebivolol is a compound that has been reported to improve nitric oxide release. We evaluated the effects of nebivolol in a rat liver ischemia/reperfusion model. METHODS: A total of 40 rats were randomly divided into four groups (n = 10 each). Group I underwent only laparotomy, Group II was administered nebivolol and then underwent laparotomy, Group III underwent laparotomy and hepatic ischemia/reperfusion, and Group IV was administered nebivolol and then underwent laparotomy and hepatic ischemia/reperfusion. Serum AST, ALT, urea, and creatinine levels, and TAS and TOS levels of liver, lung, and kidney tissues were determined. Histopathological determination was also performed. RESULTS: Nebivolol significantly reduced liver function tests in group IV, but it did not improve renal functions. Oxidative stress and abnormal histopathological findings were found to be reduced in liver tissue in group IV. Although the oxidative stress was increased after hepatic ischemia/reperfusion, nebivolol could not reduce the oxidative stress in kidney tissue. There were no significant differences between group III and group IV in terms of the histopathological changes in kidney tissue. There were no significant differences in lung tissue between the groups. CONCLUSIONS: The results of this study suggest that nebivolol has protective effects on liver but not on distant organs in a hepatic ischemia/reperfusion injury model. These experimental findings indicate that nebivolol may be useful in the treatment of hepatic ischemia/reperfusion injury.

RESUMO

BACKGROUND: The aim of this study was to evaluate the long-term outcomes of renal transplantation from Hbs Ag-positive donors to Hbs Ag-negative recipients. MATERIAL AND METHODS: A total of 78 patients who underwent renal transplantation in our clinic between January 2006 and May 2014 were included in the study. Patients were divided into 2 groups: Group 1: Donor Hbs Ag (+) (n=26, Hbs Ab (-), Hbe Ag (-), Hbe Ab (+), Hbc Ig total (+) and HBV DNA (+), male/female (M/F): 16 (61.5%)/10 (38.5%), and Group 2: Donor Hbs Ag (-) (n=52, M/F: 41 (78.8%)/11 (21.2%). Hbs Ab levels were similar in recipients in both groups. Data were collected retrospectively. Analyses were performed by using SPSS 20.0 software, and patient and graft survival were measured by using Kaplan-Meier survival curve and compared by using the log-rank test. RESULTS: Demographic data were similar in the 2 groups. The rate of acute Hepatitis B infection was significantly higher in Group 1 than in Group 2 [n=3 (11.5%) vs. n=0 (0%), respectively, p=0.012]. Acute hepatitis B attacks were detected in vaccinated patients. Graft survival rates (groups 1 and 2, respectively; at 1st, 3rd, 5th and 8th years: 95% vs. 96%, 95% vs. 94%, 85% vs. 88%, 85% vs. 82%, p=0.970) and patient survival rates (p=0.098), acute rejection rates (p=0.725), delayed graft function, chronic allograft dysfunction, new-onset diabetes after transplantation (NODAT), cytomegalovirus infection, and the need for postoperative dialysis and plasmapheresis were similar between groups. CONCLUSIONS: Our study revealed that the risk of developing acute hepatitis B was higher in patients renally transplanted from Hbs Ag (+) donors, but the other clinical outcomes were similar between groups.

RESUMO

OBJECTIVE: Peptic ulcer perforation continues to be a major surgical problem. In this study, risk factors that influence morbidity and mortality in perforated peptic ulcer disease were examined. MATERIAL AND METHODS: Files of 148 patients who were included in the study due to peptic ulcer perforation between January 2006 and December 2010 were retrospectively analyzed. Data regarding age, gender, complaints, time elapsed between onset of symptoms and hospital admission, physical examination findings, co-morbid diseases, laboratory and imaging findings, length of hospital stay, morbidity and mortality were recorded. RESULTS: The study group included 129 (87.2%) male and 19 (12.8%) female patients. The mean age was 51.7±20 (15-88) years. Forty five patients (30.4%) had at least one co-morbid disease. In the postoperative period, 30 patients (20.3%) had complications. The most common complication was wound infection. Mortality was observed in 27 patients (18.2%). The most common cause of mortality was sepsis. Multivariate analysis revealed age over 60 years, presence of co-morbidities and Mannheim peritonitis index as independent risk factors for morbidity. Age over 60 years, time to admission and Mannheim peritonitis index were detected as independent risk factors for mortality. CONCLUSION: Early diagnosis and proper treatment are important in patients presenting with peptic ulcer perforation.

RESUMO

Our objective for this study was to discuss the usability of mean platelet volume, which is associated with numerous vascular pathologies, in the early diagnosis of acute mesenteric ischemia. Acute mesenteric ischemia is an uncommon, life-threatening clinical condition mostly seen in the elderly. Early diagnosis of acute mesenteric ischemia and correction of blood circulation before necrosis occurs are important factors affecting prognosis. A total of 95 patients who underwent emergency surgery for acute mesenteric ischemia and 90 healthy volunteers as control group were included in this study. Age, gender, hemoglobin values, white blood cell counts, mean platelet volume, and platelet counts are recorded for evaluation. The mean platelet volume values were significantly higher in patients with acute mesenteric ischemia than in the controls (9.4 ± 1.1 fL and 7.4 ± 1.4 fL, respectively; P < 0.001). Receiver-operating characteristic analysis demonstrated a cutoff value of mean platelet volume as 8.1 fL (area under the curve, 0.862), a sensitivity of 83.2%, and a specificity of 80%. As a result, in the patients who are admitted to the hospital with acute nonspecific abdominal pain and suspected of having acute mesenteric ischemia, high mean platelet volume values in routine hemograms support the diagnosis of acute mesenteric ischemia.

RESUMO

BACKGROUND: The purpose of this study was to investigate the effect of Sulforaphane on ischemia/ reperfusion (IR) injury of the liver and distant organs resulting from liver blood flow arrest. MATERIALS AND METHODS: Fourty Wistar rats were assigned into four groups, each included 10 rats were used. Group I as only laparatomy, Group II laparatomy and Sulforaphane application, Group III hepatic IR; and Group IV as hepatic IR and Sulforaphane application group. Animals were subjected to liver ischemia for 30 min and then reperfusion is started. 5 mg/kg Sulforaphane was applied via oral lavage 15 minutes before initiating the experimental study. Blood samples were taken from the animals for biochemical analysis at 60th minutes of the experiment in the first and second groups; 30 minutes after beginning reperfusion in the third and forth groups. Simultaneously, liver, lung and kidney tissues were sampled for biochemical and histopathological examinations. RESULTS: The administration of sulforaphane significantly reduced the serum TOA and liver TOA levels, increased the serum TAC and liver TAC levels and also decreased The OSI and liver OSI levels. In the histopathologic examination, the injury was reduced by the administration of sulforaphane. Administration of sulforaphane did not lead to any significant changes in any parameter including histopathological parameters in both the kidney and the lung. CONCLUSIONS: Sulforaphane reduced the liver oxidative stress from I/R injury. A histological injury in liver was reduced by sulforaphane administration. However, there were no significant effects of sulforaphane on the remote organ injuries induced by IR.

RESUMO

BACKGROUND: The aim of this study was to investigate the protective effects of L-glutamine (GLN) against liver and kidney injury caused by acute toxicity of deltamethrin (DLM). MATERIAL AND METHODS: Thirty-two rats were indiscriminately separated into 4 groups with 8 rats each: control group (distilled water; 10 ml/kg, perorally [p.o.]), DLM group (35 mg/kg p.o. one dose.), GLN group (1.5 gr/kg, p.o. single dose.) and DLM (35 mg/kg p.o. one dose.) + GLN group (1.5 gr/kg, p.o. one dose after 4 hours.). Testing for total antioxidant status (TAS), total oxidant status (TOS), interleukin-1 beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) analyses were performed on tissue samples, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), urea, and creatinine were analyzed on serum samples. Liver and kidney samples were histopathologically analyzed. RESULTS: The TOS level in liver was significantly higher in the DLM group than in the control group, and the level in DLM+GLN group was considerably lower than in the DLM group. The TAS level in the DLM+GLN group was considerably higher than in the control and DLM groups. The TAS level in kidney tissues was considerably lower in the DLM group than in controls, but was similar to other groups. Histopathological analyses of liver tissues established a significant difference between DLM and DLM+GLN groups in terms of grade 2 hepatic injury. However, no significant difference was found between DLM and DLM+GLN groups in terms of kidney injury. CONCLUSIONS: Glutamine leads to significant improvement in deltamethrin-induced acute hepatotoxicity in terms of histopathologic results, tissue oxidative stress parameters, and serum liver function marker enzymes.

RESUMO

We aimed to present our clinical experience with FG treatment. Fournier's gangrene (FG) is a rare but serious disease characterized by progressive necrosis in the genitourinary and perineal region. The retrospective study included 43 patients. Patients were divided into 2 groups as survivors and nonsurvivors. Included in the analysis were data pertaining to demographics, predisposing factors, comorbidities, results of bacteriologic analyses, number of debridements, duration of treatment, FG Severity Index (FGSI) score, fecal diversion methods (trephine ostomy or Flexi-Seal Fecal Management System-FMS), and dressing methods (wet or negative aspiration system). In the nonsurvivor group, urea, WBC, and age were significantly higher, whereas albumin, hematocrit, platelet count, and length of hospital stay (LOHS) were significantly lower compared to the survivor group. Mean FGSI was lower in survivors in comparison with nonsurvivors (5.00 ± 1.86 and 10.00 ± 1.27, respectively; P < 0.001). We conclude that FGSI is an important predictor in the prognosis of FG. Vacuum-assisted closure (VAC) should be performed in compliant patients in order to enhance patient comfort by reducing pain and the number of dressings. Fecal diversion should be performed as needed, preferably by using FMS. The trephine ostomy should be the method of choice in cases where an ostomy is necessary.

RESUMO

CONTEXT: Deltamethrin (DLM) is an insecticide commonly used to protect agricultural crops against pests. QT prolongation with malignant ventricular arrhythmias are amongst the most common cardiovascular complications. DLM intoxication cause decreased level of antioxidant enzymes. Glutamine is the precursor of glutathione which is an antioxidant and has been demonstrated to improve outcome after several critical illnesses. OBJECTIVE: We hypothesized that glutamine, by means of antioxidant characteristics, may antagonize the cardiotoxic effects of DLM. MATERIALS AND METHODS: All experiments were performed on 8-week-old male Wistar albino rats. The rats were divided into following groups (n = 10); Group I: control, Group II: l-glutamine, Group III: DLM, Group IV: DLM and after 4 h l-glutamine. Total antioxidant status (TAS), total oxidant status (TOS) and parameter analyses were performed in cardiac tissue. RESULTS: We found that TAS was higher and TOS lower in DLM group. We also found that interstitial edema and inflammatory cell infiltration was significantly more frequent in DLM group and QT and QTc of DLM group were higher than others. DISCUSSION: Recent studies have shown that several special amino acids, such as glutamine, glycine, arginine and taurine, exhibit cytoprotective effect on the cardiocyte, and have established the cardioprotective properties of glutamine. CONCLUSION: In this study, we showed the protective role of glutamine against cardiotoxic effects of DLM in rats. This protective effect was confirmed by showing both tissue level improvement in oxidative stress markers and improvement in prolonged QT interval.

RESUMO

The aim of this study was to analyze the presence of malignancy in patients with Hashimoto's thyroiditis and to investigate the reliability of preoperative fine-needle aspiration biopsy (FNAB). The retrospective study included 44 patients who were operated on for nodular goiter between December 2010 and October 2011. The patients underwent thyroidectomy following a cytologic analysis plus FNAB. Hashimoto's thyroiditis was confirmed on histopathology in all patients. FNAB results were defined as benign in 14 (31.8%), suspicion for malignancy in 17 (38.6%), malignant in 9 (20.5%), and inadequate in 4 (9.1%). Following the thyroidectomy, presence of papillary thyroid carcinoma and follicular variant of papillary thyroid carcinoma were detected in 10 patients (22.7%) and 1 (2.3%) patient, respectively. The FNAB results were interpreted in terms of malignancy, which revealed the sensitivity as 80%; specificity, 40%; false positives, 69.2%; false negatives, 14.3%; positive predictive value, 31.8%; negative predictive value, 85.7%; and diagnostic accuracy, 50%. The coexistence of Hashimoto's thyroiditis with papillary thyroid carcinoma is quite common. The FNAB results for such cases are hard to evaluate, and they are likely to increase the number of false positives.

RESUMO

As a serious complication of cholelithiasis, gangrenous cholecystitis presents greater mortality than noncomplicated cholecystitis. The aim of this study was to specify the risk factors on mortality. 107 consecutive patients who underwent surgery due to gangrenous cholecystitis between January 1997 and October 2011 were investigated retrospectively. The study included 60 (56.1%) females and 47 (43.9%) males, with a mean age of 60.7 ± 16.4 (21-88) years. Cardiovascular diseases were the most frequently accompanying medical issues (24.3%). Thirty-six complications (33.6%) developed in 29 patients, and surgical site infection was proven as the most common. Longer delay time prior to hospital admission, low white blood cell count, presence of diabetes mellitus, higher blood levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and total bilirubin, pericholecystic fluid in abdominal ultrasonography, and conversion from laparoscopic surgery to open surgery were identified as risk factors affecting mortality (P < 0.001, P = 0.001, P = 0.044, P = 0.005, P = 0.049, P = 0.009, P = 0.022, P = 0.011, and P = 0.004, respectively). Longer delay time prior to hospital admission and low white blood cell count were determined as independent risk factors affecting mortality.

RESUMO

BACKGROUND: The aim of the present study is to discuss the possible role of mean platelet volume as a new predictor in the diagnosis of necrotizing pancreatitis. METHODS: Study subjects are arranged in three different groups: Group I; control group (n= 40), Group II; acute pancreatitis (n= 40), Group III; necrotizing pancreatitis (n= 36). Demographic data and mean platelet volume values are recorded retrospectively. RESULTS: Mean platelet volume of patients in Group II was 7.9±0.53, while in Group III patients it was 7.2±0.52 (p<0.001). When we compared the study groups with ROC analysis, results demonstrated that cut off value of necrotizing pancreatitis patients as 7,8 (area under curve: 0.857), sensitivity as 86.1% and specificity as 72.5%. CONCLUSION: The current study shows that mean platelet volume in necrotizing pancreatitis patients is significantly reduced compared to that of patients in the control and acute pancreatitis group.

RESUMO

OBJECTIVE: Breast cancer is the most common malignancy and the most common cause of mortality in women worldwide. In addition to the increasing incidence of breast cancer, the length of hospital stay (LOS) after breast cancer surgery has been decreasing. Because LOS is key in determining hospital usage, the decrease in the use of hospital facilities may have implications on healthcare planning. The purpose of this study was to evaluate the factors affecting postoperative LOS in patients with breast cancer. MATERIALS AND METHODS: Seventy-six in patients with breast cancer, who had been treated between July 2013 and December 2014 in the General Surgery Clinic of Dicle University, were included in the study. The demographic characteristics of the patients, treatment methods, histopathological features of the tumor, concomitant diseases, whether they underwent neoadjuvant chemotherapy or not, and the length of drain remaining time were retrospectively recorded. RESULTS: There was a correlation between drain remaining time, totally removed lymph node, the number of metastatic lymph node, and LOS. LOS of patients treated with neoadjuvant chemotherapy was longer. The patients who underwent breast-conserving surgery had a shorter LOS. Linear regression analysis revealed that the drain remaining time and the number of metastatic lymph nodes were independent risk factors for LOS. CONCLUSION: Consideration should be given to cancer screening to diagnose the patients before lymph node metastasis occurs. In addition, drains should be avoided unless required and, if used, they should be removed as early as possible for shortening LOS.

RESUMO

OBJECTIVE: The aim of this study was to determine the effect of curcumin on adhesion formation in a rat cecum abrasion model. MATERIALS AND METHODS: Thirty Wistar rats were randomized into three groups; the control group received saline, the curcumin group received 10 mg/kg of curcumin after cecal abrasion, and in the sham group the abdominal wall was closed without any abrasion to the cecum. On day 15, adhesions were assessed blindly using a standardized scale, and histopathological samples were taken and examined. RESULTS: There were no incisional hernias or wound dehiscences in any animals of the three groups. A comparison of adhesion scores showed a significant difference between the curcumin (median = 1) and the control group (median = 2; p < 0.05). The grade of inflammation of the curcumin (median = 1) and the sham (median = 0) group was significantly lower than that of the control group (median = 3; p < 0.01 and p < 0.001, respectively). Hydroxyproline levels were significantly lower in the sham (48.3 ± 11.8 µg/mg) and the curcumin (63.8 ± 13.9 µg/mg) group compared to the control group (85.7 ± 22.1 µg/mg; p < 0.05). CONCLUSION: These data suggest that curcumin, administered intraperitoneally, was effective in the prevention of peritoneal adhesion formation.
