The effect of ileal resection length on postoperative complications and prognosis in right colon cancer.

BACKGROUND: There is a lack of literature on the length of the terminal ileum to be resected in right hemicolectomy for colon cancer. Therefore, we aimed to determine the mean ileal loop length and the effect of this variation on postoperative complications and long-term oncological outcomes in patients who underwent right hemicolectomy. METHODS: Right hemicolectomy surgeries performed for colon cancer in a tertiary care hospital between January 2011 and December 2018 were retrospectively analyzed from a prospective database. Two patient groups were established based on the mean length of the resected ileum above and below 7 cm. The two groups were compared for clinicopathological data, postoperative complications, mortality, long-term overall survival (OS) and disease-free survival (DFS). The factors contributing to OS and DFS were analyzed. RESULTS: The study included 217 patients. Body mass index (BMI) values were significantly higher in the ileum resection length > 7 cm group (p = 0.009). Pathological N stage, tumor diameter, and number of metastatic lymph nodes were significantly higher in the ileum resection length > 7 cm group (p = 0.001, p = 0.001, and p = 0.026, respectively). There was no significant difference for postoperative complication and mortality rates between the two groups. The mean follow-up period was 61.2 months (2-120) in all patients. The total number of deaths was 29 (11.7%) while the 60-month OS was 83.5% and 50-month DFS was 81.8%. There was no significant difference between the groups in terms of OS and DFS rates (p > 0.05). CONCLUSIONS: Excessive resection of the distal ileum in right hemicolectomy does not provide any benefit in terms of prognosis and complications.The ileum resection length and values close to it in our study appear to be sufficient.

Handmade Loop Versus Hem-o-Lok Clip in Closure of Appendiceal Stump During Laparoscopic Appendectomy: Limited Setting in a Peripheral University Hospital.

Background: Today, laparoscopy is frequently used in abdominal emergencies such as acute appendicitis. There are several techniques used to close the appendiceal stump during laparoscopic appendectomy. We aimed to compare the use of handmade loop and Hem-o-lok used to close the appendiceal stump in public hospitals where resources are limited, in terms of surgical outcomes and cost. Methods: Between January 2020 and December 2022, patients for whom handmade loops and Hem-o-loks were used to close the appendiceal stump during laparoscopic appendectomy in our clinic were included in the study. There were a total of 638 patients (mean age: 33 ± 13.5 years, 325 females and 313 males) in the patient cohort. Demographic and clinical data, duration of surgery, complications, hospital stay, pathology reports, mortality, and cost of supplies were compared between the two groups. Results: There were 308 patients in the handmade loop group (160 females, 148 males, mean age: 33.7 years, range: 18-85 years) and 330 patients in the Hem-o-lok group (166 females, 164 males, mean age: 32.5 years, range: 18-89 years). There was no significant difference between the two groups for American Society of Anesthesiologists score, duration of symptom, hospital stay, intensive care unit stay, preoperative laboratory values, histopathological results, mortality, and morbidity (P > .05). The mean operation time was 48.76 ± 16.16 minutes in the handmade loop group and 40.53 ± 11.63 minutes in the Hem-o-lok group (p = 0.001). In terms of cost, the cost per case of Hem-o-lok group was about 25.8 times as much as the group that used sutures ($31 versus $1.2). Conclusions: Both methods can be used safely in laparoscopic appendectomy. The use of Hem-o-lok has no advantage other than shortening the operation time. However, it is costlier. Especially in peripheral hospitals where resources are limited, closing the appendiceal stump using a handmade loop is an easy, safe, and cost-effective method.

Lymphocyte-to-C-reactive protein ratio as a new biomarker for predicting mortality and morbidity in Fournier's gangrene.

OBJECTIVE: The purpose of this study was to research the neutrophil-lymphocyte ratio (NLR), lymphocyte-to-C-reactive protein ratio (LCR), and Fournier's Gangrene Severity Index (FGSI) for predicting prognosis and mortality in patients with Fournier's gangrene (FG). MATERIAL AND METHODS: Patients diagnosed with FG and treated in a tertiary referral hospital in the period from January 2013 to June 2020 were reviewed. LCR, FGSI, and NLR values were calculated. RESULTS: Our series included a total of 41 patients. Of the patients, 78% survived and 21.9% (n = 9) died. Survivors were significantly younger than non-survivors (p = 0.009). Hospital costs were higher in non-survivors and close to statistical significance (p = 0.08). The ROC analysis revealed that the FGSI, LCR, and NLR parameters were significant in identifying survivors and non-survivors (AUC = 0.941 [0.870-1.000], p < 0.001; AUC = 0.747 [0.593-0.900], p = 0.025; and AUC = 0.724 [0.548-0.900], p = 0.042). CONCLUSION: A low LCR value can be used as a marker to assess mortality and disease severity in patients with Fournier's gangrene.

OBJETIVO: Investigar el cociente neutrófilos-linfocitos (CNL), el cociente linfocitos-proteína C reactiva (CLP) y el índice de gravedad de la gangrena de Fournier (IGGF) para predecir el pronóstico y la mortalidad en pacientes con gangrena de Fournier (GF). MÉTODO: Se revisaron los pacientes diagnosticados de GF y atendidos en un hospital de tercer nivel de referencia en el período de enero de 2013 a junio de 2020. Se calcularon los valores de CLP, IGGF y CNL. RESULTADOS: Nuestra serie incluyó 41 pacientes, de los cuales el 78% sobrevivieron y el 21.9% (n = 9) fallecieron. Los supervivientes eran significativamente más jóvenes que los no supervivientes (p = 0.009). Los costes hospitalarios fueron mayores en los no supervivientes y cercanos a la significación estadística (p = 0.08). El análisis ROC reveló que los parámetros IGGF, CLP y CNL fueron significativos para identificar supervivientes y no supervivientes (AUC: 0.941 [0.870-1.000], p < 0.001; AUC: 0.747 [0.593-0.900], p = 0.025; AUC: 0.724 [0.548-0.900], p = 0.042). CONCLUSIONES: Un valor bajo de CLP se puede utilizar como marcador para evaluar la mortalidad y la gravedad de la enfermedad en pacientes con GF.

The incidence of biliary sludge in first trimester pregnancies with hyperemesis gravidarum and its effect on the course of hyperemesis gravidarum.

Pregnancy is one of the risk factors for biliary sludge (BS) formation. In this cross-sectional study, a total of 959 pregnant women were included. Serum aspartate aminotransferase, alanine aminotransferase, sodium, potassium, triglycerides, cholesterol levels and the presence of ketones in urine were determined. The presence of BS was investigated using maternal abdominal ultrasound. The incidence of BS in pregnancies complicated by hyperemesis gravidarum (HG) was 14%. The degree of ketonuria and low birth weight were statistically higher in pregnancies with maternal BS than women without sludge. Total weight gain during pregnancies with BS was statistically lower than controls. The incidence of BS in pregnancies with HG does not appear to increase due to HG-related complications, such as dehydration, starvation and weight loss. However, the severity of HG may be worse when HG is associated with sludge.Impact StatementWhat is already known on this subject? The incidence of biliary sludge (BS) in pregnant women ranges between 10.9% and 36%. Some clinical conditions, such as pregnancy, prolonged fasting, total parenteral nutrition, rapid weight loss and ceftriaxone treatment can play a role in the formation of gallbladder sludge.What do the results of this study add? This is the first study to investigate the incidence of BS in hyperemesis gravidarum (HG) pregnancies. Results show that HG may transiently be associated with BS. HG is more likely to cause a transient increase in new sludge formation. The symptoms and complications related to HG may be more severe when HG is associated with BS.What are the implications of these findings for clinical practice and/or further research? Our study showed that BS can be found in HG patients, and HG can be a predisposing factor for new sludge formation, although this association is generally driven by advanced maternal age and increased baseline serum lipid and alanine aminotransferase levels. BS may also be independently associated with an increased risk of subsequent preterm delivery in women with HG.

Do haematological parameters such as HALP and Lymphocyte to C-reactive protein ratio predict tumor response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer?

AbstractAim:Inflammatory markers are effective in determining the prognosis of malignant diseases. The aim of this study is to investigate the relationship of HALP and LCR with tumor response after neoadjuvant chemoradiotherapy and their effects on prognosis in patients with locally advanced rectal cancer. METHODS: 88 patients who received nCRT with the diagnosis of LARC were included in the study. First, all patients were divided into 2 groups: patients with pathological and clinical complete response (pCR+cCR) group 1 and patients with non-complete response group 2. The 82 patients who underwent surgery were divided into two groups according to the TRG Dworak: good response and poor response groups. Inflammation markers such as HALP and LCR were obtained using biochemical parameters. RESULTS: HALP and LCR were higher in the complete response group than in the none-complete response group (p<0.05). When TRG 3-4 (good response group) and TRG 0-1-2 (poor response group) were compared, HALP and LCR were higher in the good response group (p<0.05). The cut-off point for the HALP value was 30.17, the sensitivity was 88.2%, and the specificity was 43.7%. The cut-off point for the LCR value was 0.402, the sensitivity was 88.2%, and the specificity was 63.4%. It was found that HALP and LCR calculated prior to neoadjuvant CRT could not predict overall survival. CONCLUSIONS: We believe that inflammatory markers such as HALP and LCR can effectively identify rectal cancer patients who respond best to nCRT.

A new modification of the Trapdoor Procedure without surgical hip dislocation in the management of patients with osteonecrosis of the femoral head: A retrospective case series.

OBJECTIVE: The aim of this paper was to investigate the mid-term results of a modified Trapdoor procedure that can allow grafting of the femoral head without surgical hip dislocation in the management of patients with osteonecrosis of the femoral head. METHODS: 16 hips of 12 patients (7 female, 5 male; mean age = 38.5 ± 10.7) surgically treated by the new modification of Trapdoor procedure were retrospectively reviewed and included in the study. Based on the Association Research Circulation Osseous (ARCO) classification system, seven hips (43.7%) were stage 2, and nine hips (56.3%) were stage 3. The mean follow-up was 48.4 ± 25.7 months (range = 12-107). All the patients were evaluated postoperatively at the 6th week, 3rd month, 6th month, 1st year, and annually thereafter until their final follow-up. Clinical assessment was performed using the Harris Hip scoring (HHS) system, Non-Arthritic Hip score (NAHS) and Visual analogue pain scale (VAS). At the final follow-up, degenerative changes were examined according to the Kellgren-Lawrence scale. RESULTS: ThemeanHHS increased from53.43 ± 9.0 (range = 36-67) preoperatively to 83.81 ± 6.1 (range = 72-95) at the final follow-up (P < 0,001). Themean NAHS increased from 51.5 ± 8.2 (range = 36.25-61.25) preoperatively to 86 ± 3.2 (range = 81.5-90) (P < 0,001) at the final follow-up. The mean preoperative VAS decreased from 7.85 ± 0.9 (range = 6.45-9.5) to 3.05 ± 0.9 (range = 1.6-5.2) (P < 0,001) at the final follow-up. 13 hips demonstrated 80 and higher scores according toHHS. In the remaining three hips (ARCOstage 3), the mean postoperative HHS, NAHS, and VAS scores were 76, 82, and 3,2 respectively. According to Kellgren-Lawrence scale, three hips (18,75%) were determined as grade 0, 10 hips (62.5%) as grade 1, and 3 hips (18.75%) as grade 2. CONCLUSION: The Modified Trapdoor procedure without surgical hip dislocation seems to be a suitable technique with favorable clinical outcomes for the treatment of ARCO stage 2 and stage 3 osteonecrosis of the femoral head. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

Longitudinal Epiphyseal Bracket as an Overlooked Etiology of Congenital-Residual Hallux Varus: A Case Report.

Longitudinal epiphyseal bracket is a rare ossification disorder of the short tubular bones. The affected bone becomes deformed as a result of the bracket. The normal growth pattern cannot occur, and when it affects the first metatarsal bone, hallux varus may develop with the abnormal growth pattern. We present such a 6-year-old patient who had undergone surgery at 6 months of age for hallux varus and polydactyly. The deformity had worsened gradually after the initial operation because of the overlooked longitudinal epiphyseal bracket. The patient was treated with surgical excision of the epiphyseal bracket, with corrective medial open wedge osteotomy and split transfer of the extensor hallucis longus tendon. The result was excellent at the 20-month follow-up. At an early age, patients who present with hallux varus must be checked for the epiphyseal bracket, which can be invisible on radiographs because of the chondral structure. Untreated or overlooked patients with epiphyseal bracket will need revision operations for recurrent deformities.

Dynamic changes in aortic stiffness after substantial weight loss by laparoscopic sleeve gastrectomy in patients with obesity: a 1-year follow-up study.

Arterial stiffness has been identified as a powerful and independent risk factor for cardiovascular disease. Obesity is associated with an increased risk of aortic stiffness (AS) and adverse cardiovascular events. Herein, we aimed to evaluate the effects of weight loss after laparoscopic sleeve gastrectomy (LSG) on AS in individuals with morbid obesity by using the transthoracic echocardiography (TTE).A total of 53 patients with obesity (17 males, 36 females) who underwent LSG and did not have any known heart disease were included in the study. The AS parameters were measured with TTE. The demographic and echocardiographic data of the patients were studied before, at 1 month and 12 months after surgery.The mean age of the study group was 34.41±11.62, 68% of whom were female. There were no significant differences in terms of the standard echocardiography and Doppler measurements as compared with preoperative values (all p>0.05). When the elastic parameters of the aorta were compared, no significant differences were detected regarding aortic strain (%) ((16.28±4.11) vs (16.68±4.56), p=(0.998)), distensibility (cm2/dyn) ((6.74±1.78) vs (7.03±2.31), p=(0.997)) and Aortic Stiffness Index values ((10.73±3.84) vs (10.63±3.34), p=0.998) between baseline and first month after surgery. In the 12-month follow-up, it was determined that the aortic strain ((16.28±4.11) vs (22.74±5.79), p≤0.001) and distensibility ((6.74±1.78) vs (10.34±3.059), p<0.001)) values increased at significant levels.Weight loss by LSG improves arterial stiffness parameters in patients with obesity over a 1-year follow-up.

Favorable electrocardiographic changes after substantial weight loss in patients with morbid obesity : Results of a prospective study.

BACKGROUND: Obese patients have an increased risk of arrhythmias and sudden death, even in the absence of structural heart disease and cardiac dysfunction. This study aimed to determine whether weight loss by bariatric surgery has an effect on arrhythmia-related electrocardiographic (ECG) variables in morbidly obese patients. METHODS: In this prospective study, the data of 48 patients were analyzed. All ECG variables that have the potential to predict ventricular arrhythmia were evaluated before surgery, and were compared with the 1­month and 6­month follow-up results. RESULTS: The mean body mass index was 45.74 ± 5.60 kg/m2 before surgery. There was a statistically significant decline in body mass index in the first and sixth month after surgery (39.26 ± 5.00 kg/m2 and 31.71 ± 4.49 kg/m2, respectively; p < 0.001). Furthermore, notable reduction was found in terms of heart rate measurements-QTc­d, JTc, JTc­d, Tp­e, TP-e/QT, TP-e/QTc-in the first month and sixth month compared with baseline (p < 0.001 for all comparisons). Several ECG variables, such as heart rate (r = 0.369, p = 0.001), QTc­d (r = 0.449, p = 0.001), JTc­d (r = 0.324, p = 0.002), Tp­e (r = 0.592, p = 0.001), Tp-e/QTc (r = 0.543, p = 0.001), Tp-e/JTc (r = 0.515, p = 0.001), exhibited a positive and significant correlation with weigh loss. Moreover, a negative and weakly significant correlation was found between the index of cardiac electrophysiological balance (r = -0.239, p = 0.004) and body mass index. CONCLUSION: Substantial weight loss following laparoscopic sleeve gastrectomy in obese patients is accompanied by a significant improvement in ventricular repolarization. Therefore, this effect may lead to a decrease in the incidence of lethal ventricular arrhythmia and sudden cardiac death.

Short- and mid-term effects of sleeve gastrectomy on left ventricular function with two-dimensional speckle tracking echocardiography in obese patients.

AIM: This study aimed to investigate left ventricular functions of obese patients with no known heart disease who underwent laparoscopic sleeve gastrectomy by speckle tracking echocardiography in their early and medium-term postoperative follow-up. PATIENTS AND METHOD: Thirty-seven obese patients (10 M, 27 F) without coronary artery disease or heart failure who had undergone LSG were included in the study. Apical four-, three-, and two-chamber images were analyzed longitudinally by conventional methods and speckle tracking echocardiography (STE) for left ventricle functions preoperatively, at the postoperative Month 1 and at the postoperative Month 6 (QLAB 6.0), using current software. RESULTS: No difference was found between standard echocardiography and Doppler parameters in terms of the 1-month versus 6-month follow-up values compared to baseline. Left ventricular STE longitudinal measurements demonstrated significantly higher longitudinal strain and strain velocity parameters in the follow-up values at Month 6 compared to the values at Month 1 and at baseline. Global longitudinal strain (GLS) was -17.48 ± 1.09% in 6-month follow-up, -16.16 ± 1.26% in 1-month follow-up, and -16.06 ± 1.25% at baseline (P < .001). A significant correlation was found between delta GLS, which represents patients' GLS change in 6 months, and delta weight, which represents patients' body weight change in 6 months. CONCLUSION: Obese patients who had undergone LSG were observed to have improved left ventricular function in the mid-term.

Effect of sildenafil citrate on the liver structure and function in obstructive jaundice: An experimental study.

OBJECTIVE: We aimed to investigate the effect of 10 mg/kg sildenafil on the structure and function of the liver in a rat model of obstructive jaundice. MATERIAL AND METHODS: Sixty-two male Wistar albino rats were distributed into six different groups. Obstructive jaundice was performed by legating the common bile duct. 10 mg/kg sildenafil citrate in drinking water was delivered orally after the operation before sacrificing them. Rats were sacrificed either after 10 or 28 days according to the study design. The blood and tissue samples from the liver were obtained to perform a biochemical and histopathological analysis to study functional and structural changes in the liver. RESULTS: At the 10th day, there was no difference between the sildenafil-treated and control groups with regard to the aspartate aminotransferase and alanine aminotransferase levels (p=0.423, p=0.661). The alkaline phosphatase total bilirubin levels among the groups were statistically different (p<0.001). At the 28th day, liver function tests except alanine aminotransferase showed significant differences among the groups (p<0.001). Liver function tests did not changed significantly between the 10th and 28th day in sildenafil-treated rats (p>0.05). Significant differences were observed among the groups with regard to cholestasis, fibrosis, inflammation, and necrosis (p<0.001). However, edema increased in the sildenafil-treated group (p<0.001). On the 28th day, the severity of structural changes in the liver after obstructive jaundice, except edema, reduced significantly (p<0.001). The sildenafil-treated groups at different time points didn't show any statistical difference in histopathological changes (p>0.05). CONCLUSION: Oral administration of 10 mg/kg sildenafil citrate dramatically reverses the biochemical and histopathological liver changes induced by obstructive jaundice in rats.

Melatonin exhibits supportive effects on oxidants and anastomotic healing during intestinal ischemia/reperfusion injury.

BACKGROUND: The aim of this study was to investigate the effects of melatonin on intestinal anastomosis after intestinal ischemia/ reperfusion injury (IRI). METHODS: Thirty Wistar albino rats of both sexes were divided into 3 groups: sham, control, and treatment. IRI was performed by clamping the superior mesenteric artery (SMA) for 30 minutes, followed by reperfusion. The sham rats received only manipulation of the SMA. Melatonin (10 mg/kg) was administered to the treatment group, and the control group was given a vehicle injection. Both the treatment group and the control group further underwent ileal resection of a 1-cm segment and anastomosis. On the postoperative seventh day, the anastomotic burst pressure, hydroxyproline level, histological indices of wound healing, and oxidative parameters of catalase (CAT), superoxide dismutase (SOD), total glutathione (T-GSH), and glutathione peroxidase (GSH-Px) levels were measured. A one-way analysis of variance and chi-square test were used for the categorical data. RESULTS: Melatonin treatment led to a significantly higher burst pressure (p=0.027 and p<0.001, respectively). The 2 antioxidant enzymes, CAT and SOD, were at the highest level in the sham and melatonin groups and the lowest level in the control group (p=0.001 and p=0.002, respectively). Melatonin treatment resulted in a significantly higher level of both enzymes compared with the control group (p=0.026 and 0.003, respectively). The GSHpx and total GSH levels were slightly elevated in the treated rats, but the difference was not statistically significant (p=0.205 and 0.216, respectively). Fibroblast infiltration, capillary formation, and epithelialization were significantly better in the melatonin-treated animals. The granulocyte and mononuclear infiltration scores were similar between all groups. CONCLUSION: It was concluded that melatonin had marked effects on intestinal anastomotic healing during intestinal IRI.

The Effect of Peritoneal Prednisolone Lavage in Bacterial Peritonitis: An Experimental Study.

OBJECTIVE: This study investigated and compared the effects of antibiotic and steroid lavage on survival and cytokine levels in an experimental abdominal sepsis model. BACKGROUND: In abdominal sepsis, abdominal lavage with saline or antibiotic solutions is a well-documented intervention known to have positive impact on survival; however, the effects of steroid lavage in abdominal sepsis have not yet been investigated. MATERIALS AND METHODS: Ninety-six Wistar rats were divided into 4 groups (n = 24). Abdominal sepsis was induced by cecal ligation and puncture. Six hours after laparotomy, the authors performed a relaparatomy followed by cecal resection and an abdominal lavage. Abdominal lavage was performed using saline in group 1, equal volumes of cefazolin sodium in group 2, low-dose methylprednisolone (1 mg/kg) in group 3, and high-dose methylprednisolone (2 mg/kg) in group 4. After division of 2 subgroups from each of the 4 groups, the first of the rats (n = 12) were euthanized 6 hours later for evaluation of cytokines (ie, interleukin [IL] 1ß, 2, 4, 10, and tumor necrosis factor alpha [TNF-α]), and the others were followed for 30 days for analysis of mortality rates. RESULTS: The mortality rate of the rats in group 2 was significantly higher than group 4, which had no mortality (P = 0.032). Although insignificant, the lowest mean value of IL-1ß, IL-2, and TNF-α were in group 1, and the highest was in group 2. The lowest IL-4 level was in group 3, and the highest level was in group 2 (P = 0.41). Interleukin-10 levels were significantly lower in group 4 and higher in group 2 (P = 0.014). CONCLUSION: The authors state that peritoneal lavage with prednisolone improved survival rates with increasing doses in abdominal sepsis.

Effects of melatonin on cytokine release and healing of colonic anastomoses in an experimental sepsis model.

BACKGROUND: The present objective was to identify effects of early melatonin application on healing of anastomotic wound and inflammation in an experimental sepsis model. METHODS: A total of 60 Wistar albino rats were divided into 2 groups. Cecal ligation puncture (CLP) and colonic resection anastomosis were performed on both the control group and the melatonin treatment group. Both groups were divided into 3 subgroups consisting of 10 rats each. One subgroup from each group underwent re-laparotomy at the 16th hour, the next on the 3rd day, and the final subgroup on the 7th day. Presently evaluated were effects of melatonin treatment of early sepsis on interleukin-6 (IL-6), interleukin-10 (IL-10), interferon gamma (INF-γ), and C-reactive protein (CRP) levels, as well as burst pressures (BPs), collagen and hydroxyproline (OHP) content of the anastomotic segments, histopathologic healing, immunohistochemical expressions, CD34, and transforming growth factor beta (TGF-ß). RESULTS: IL-6 and INF-γ levels of the treatment group showed a significant decrease at the 16th hour and an increase on the 3rd and 7th postoperative days. IL-10 levels were significantly higher at the 16th hour and significantly lower on the 3rd and 7th postoperative days in the control group (p<0.001 for each). The treatment group also showed significantly higher capillary permeability, fibroblast proliferation, and collagen deposits (p<0.001 for each). CD34 expression was significantly increased in the treatment group on the 7th postoperative day (p=0.005). CONCLUSION: Application of melatonin in early sepsis significantly improved colonic anastomotic healing in a rat model.

A comparison of Chevron and Lindgren-Turan osteotomy techniques in hallux valgus surgery: a prospective randomized controlled study.

OBJECTIVE: The aim of this prospective randomized controlled single-blind study was to compare the results of Chevron and Lindgren-Turan osteotomy techniques for treatment of moderate hallux valgus. METHODS: A total of 66 female patients (34 in Chevron group, 32 Lindgren-Turan group) were recruited in this study and followed up for an average of 26.08 months. Operative procedures were performed by 2 surgeons, and patients were evaluated by an another researcher who was blinded to the surgical technique. The groups were compared for their radiological and clinical results. RESULTS: Both techniques was clinically and radiologically effective (p<0.01). However, no significant differences were found between the 2 groups regarding American Orthopaedic Foot and Ankle Society's clinical rating system, Painful Foot Evaluation scale of Maryland University scores, or radiologic evaluation (p>0.05). Compared to the Chevron group, the Lindgren-Turan group was found to have shorter surgical duration (p<0.05) and significantly more shortening at the first metatarsal (p<0.05). CONCLUSION: In moderate hallux valgus deformity, both the Chevron and Lindgren-Turan osteotomy techniques are clinically and radiologically safe, effective, and reliable alternatives. No superiority was detected in either technique. Although shortening at the first metatarsal in the Lindgren-Turan group was radiologically significant, the results were clinically tolerable.

The effect of methylprednisolone and tenoxicam on the protection of damage of the nerve physiomorphology caused by prolene mesh.

INTRODUCTION: Aim was to investigate the effect of methylprednisolone and tenoxicam on the protection of damage of the nerve physiomorphology caused by prolene mesh used in hernia repair. METHODS: Fifty male Wistar-albino rats weighing 250-350 gr, were randomly divided into 5 groups. Sciatic nerve was dissected in all rats after performing EMG on basal neural transport. In group 1, only sciatic nerve manipulation was performed. Other groups received a monofilament polypropylene cuff around the sciatic nerve. No additional procedure was performed in group 2. In group 3, 2 mg/kg single dose methylprednisolone was injected around the nerve and mesh. In group 4 and 5, 0.5 mg/kg/day methylprednisolone and 1 mg/kg tenoxicam was injected around the nerve and mesh for 4 weeks, respectively. Neural transport was evaluated by electromyography 4 weeks later and compared with pre-procedural values. Then the rats were sacrificed and, sciatic nerves including 1 cm around the mesh were excised. Inflammation and fibrosis were scored histopathologically. RESULTS: While basal latency was similar, postoperative latency was significantly different among groups. Latency was significantly longer in group 2 than the group 1. It was significantly shorter in group 3 when compared to group 2 (p = 0.007). Preoperative and postoperative amplitudes were similar among groups. Denervation was significantly different among groups (p < 0.05). Denervation was higher in group 2 than group 1. It was similar to group 2 in study groups. Inflammation and fibrosis was significantly different among groups (p < 0.05). Inflammation and fibrosis scores were significantly higher in group 2 than group 1. The highest inflammation and fibrosis scores were detected in repetitive drug administrated groups. Although it wasn't statistically significant, inflammation was lower in single dose steroid administrated group than group 2. Similarly, the highest fibrosis scores were detected in repetitive drug administrated groups. Single dose steroid administration didn't increase fibrosis when compared to group 2. CONCLUSIONS: Prolene mesh used in hernia repair caused increased inflammation and fibrosis and effected latency and denervation negatively. Single dose methylprednisolone administration decreased nerve damage and inflammation. On the other hand, daily administration of methylprednisolone and tenoxicam for 4 weeks caused increased inflammation and fibrosis and wasn't affective on protection of nerve physiomorphology.

Comparison of inguinal hernia repairs performed with lichtenstein, rutkow-robbins, and gilbert double layer graft methods.

Tension-free repairs are performed commonly in inguinal hernia operations. The objective of the present study is to compare the outcomes of three different tension-free repair methods known as Lichtenstein, Rutkow-Robbins, and Gilbert double layer. One-hundred and fifty patients diagnosed with inguinal hernia were randomly split into three groups. The comparisons across groups were carried out in terms of operation length, postoperative pain, femoral vein flow velocity, early and late complications, recurrence rates, length of hospital stay, time required to return to work, and cost analysis. No difference was found between the groups regarding age, gender, type and classification of hernia, postoperative pain, and late complications (p > 0.05). Operation length was 53.70 ± 12.32 min in the Lichtenstein group, 44.29 ± 12.37 min in the Rutkow-Robbins group, and 45.21 ± 14.36 min in the Gilbert group (p < 0.05). Mean preoperative and postoperative femoral vein flow velocity values were 13.88 ± 2.237 and 13.42 ± 2.239 cm/s for Lichtenstein group, 12.64 ± 2.98 and 12.16 ± 2.736 cm/s for Rutkow-Robbins group, and 16.02 ± 3.19 and 15.52 ± 3.358 cm/s for the Gilbert group, respectively. Statistical difference was found between all the groups (p < 0.001). However, no difference was determined between the groups regarding the decrease rates (p = 0.977). Among early complications, hematoma was observed in one (2 %) patient of Lichtenstein group, five (10 %) patients of Rutkow-Robbins group, and three (6 %) patients of Gilbert group (p = 0.033). Cost analysis produced the following results for Lichtenstein, Rutkow-Robbins, and Gilbert groups: US $157.94 ± 50.05, $481.57 ± 11.32, and $501.51 ± 73.59, respectively (p < 0.001). Lichtenstein operation was found to be more advantageous compared with the other techniques in terms of cost analysis as well as having unaffected femoral blood flow. Therefore, we believe that Lichtenstein repair is still the most appropriate surgical option in patients diagnosed with inguinal hernia.

Effect of antibiotic lavage in adhesion prevention in bacterial peritonitis.

BACKGROUND: Intra-abdominal adhesions remain a major clinical problem. Previously, rifamycin lavage was used to prevent adhesion formation in the septic abdomen. The aim of our study was to test the effectiveness of intraperitoneal application of alternate antibiotics in an abdominal sepsis model. METHODS: Sixty Wistar-albino rats were randomly divided into 6 equal groups. Bacterial peritonitis was induced using caecal ligation and puncture model in all groups. Group 1 was an untreated control. The peritoneum was lavaged with isotonic saline in Group 2, with imipenem in Group 3, with ceftriaxone in Group 4, with cefazolin in group 5 and with metronidazole in group 6. Four weeks after the surgery, intra-abdominal adhesions were graded, tensile strength of the adhesions was measured and histopathological examinations were performed. RESULTS: Imipenem, ceftriaxone and cefazolin significantly reduced adhesion formation (p<0.001) with significantly reduced fibrosis scores (p=0.013). Adhesion formation was greatest in the metronidazole treatment group. The breaking force of adhesions was significantly reduced in Groups 4 and 5 (p<0.001). Although, the inflammation scores were similar between groups (p=0.058), grade 3 inflammation scores were only seen in control, saline and metronidazole-treatment groups. CONCLUSION: According to these data, cephalosporins may be effective in preventing adhesion formation in septic abdomens. These antibiotics need to be evaluated in a clinical trial.

Traumatic ipsilateral multiple open metatarsal and calcaneal fractures with first metatarsophalangeal joint dislocation: a case report.

A 17-year-old man fell from a height of 10 m onto his right forefoot and sustained ipsilateral calcaneal, comminuted cuboid, and second, third, and fourth metatarsal neck fractures and first metatarsophalangeal joint open dislocation. This report discusses this rare injury. The authors believe that initial debridement with immediate surgical fixation and reduction with appropriate antibiotic treatment saved the patient's extremity.
