RESUMO

Desmoid tumours are rare and locally invasive neoplasms that originate from the muscles and their aponeurosis. Incomplete excision causes recurrences; therefore, patients require aggressive resection that essentially entails tumour excision with a clear surgical margin. After radical resection, the resultant wide defect may lead to difficulty in closure of the anterior abdominal wall. Here, we report a case having surgery for large desmoid tumour of the anterior abdominal wall through an abdominoplasty incision followed by an abdominal wall reconstruction with a dual-sided composite mesh.

RESUMO

Phyllodes tumors are uncommon breast neoplasms that constitute of 1-2% of breast malignancies. The tumor can mimic fibroadenoma clinically, radiologically and histologically. Ductal carcinoma in-situ in the epithelial component of phyllodes tumor is very rare. When ductal carcinoma in-situ is detected within the specimen, the management of treatment changes completely. We report a rare case of low grade ductal carcinoma in-situ arising in a malignant phyllodes tumor in a 55-year-old female patient.

RESUMO

Context: Primary hyperparathyroidism related hypercalcemic crisis (PHHC) is a condition that may result in fetal course. So, the early diagnosis and treatment of these patients are important. Objective: This study aimed to investigate the clinical features for hypercalcemic crisis (HC) by comparing the groups with and without primary hyperparathyroidism related calcemic crisis. Design: All patients operated with primary hyperparathyroidism (PH) diagnosis in a single clinic between March 2015 and March 2020 were included in this retrospective study. Subjects and Methods: 119 patients included the study.Patients with serum calcium (Ca) level > 14 mg/dl were regarded as HC and the patients were divided into two groups as HC and non-HC. These two groups were compared for demographic data, preoperative biochemical parameters, preoperative localization studies, histopathological assessment and postoperative results. Results: Serum Parathormone (PTH), Ca, Alkaline phosphatase (ALP) and creatinine values among preoperative biochemical parameters were higher in the HC group than the non-HC (p<0.005). The hyper-functional parathyroid size of the patients in the HC group was also bigger compared to non-HC (p<0.05). No difference was observed in the demographic and histopathological data, preoperative localization studies and postoperative results of the two groups (p>0.05). Conclusions: PH is usually an elective operation and PHCC treatment should be relatively more urgent as it can be mortal. Higher HC occurrence possibility should be considered in PH patients with high serum PTH, ALP and creatinine values and large tumor diameters and those patients should be prioritized for treatment.

RESUMO

Phylloides tumor in the breast is a rare fibroepithelial tumor, which is often seen in young adult women. Phylloides tumor of the breast accounts for about 1% of all breast tumors and approximately 3% of all fibroepithelial tumors. Pre-operative diagnosis is difficult. Since there aren't any specific mammography and ultrasound findings, they cannot be distinguished from fibroadenomas through these imaging methods and are mostly followed up as if they are fibroadenomas. Patients often present with the complaint of a mass that has been present for a long time and had started to grow suddenly. The primary preferred approach for treatment is wide local excision with negative surgical margins. Coexistence of invasive ductal carcinoma with phylloides tumor in the same breast is a very rare occurrence. We present in this article, a 42-year-old female patient with an invasive ductal carcinoma inside a phylloides tumor in the same breast.

RESUMO

INTRODUCTION: Alcohol consumption is frequently associated with gastric mucosal lesions. The purpose of this study was to determine the effect of Coenzyme-Q10 (CoQ10) supplementation on the ethanol-induced gastric mucosal damage in a rat model. MATERIAL AND METHOD: Sixty-four female wistar albino rats were randomly divided into 8 groups (n = 8). Studies were performed in ethanol induced gastric ulcer model in Wistar albino rats. Famotidine at a dose of 5 mg/kg or 20 mg/kg and CoQ10 at a single dose of 10 mg/kg or 20 mg/kg and 30 mg/kg for 7 days were administered as pretreatment. All the rats in study groups received 2 ml/kg ethanol 95 % intragastrically, 30 minutes after pretreatment. Four hour after ethanol administration, all rats were sacrificed and their stomachs were removed under ketamin anaesthesia. Gastric protection was evaluated by measuring the ulcer index, MDA concentrations, and histopathological studies. RESULTS AND DISCUSSION: Rats pretreated either with famotidine or CoQ10 had significantly diminished gastric mucosal damage which was assessed with gross and microscopic analysis (p < 0.00625). MDA levels were significantly lower in famotidine 20 mg/kg and CoQ10 pretreatment for 7 days group (p < 0.00625).

RESUMO

INTRODUCTION: Resveratrol (RSV) is a natural polyphenolic compound found in grape skins and the red wine which improves histological reorganization of the regenerating tissue in dermal wound healing. Since anastomotic healing possesses paramount importance to prevent complications in colorectal surgery, the present study is aimed to evaluate the effect of RSV on the healing of experimental left colonic anastomoses. METHODS: Thirty-two male Wistar albino rats were randomized into two groups and subjected to colonic anastomosis. The study group was treated with RSV and the control group received tap water instead. The rats were sacrificed 3 and 7 days postoperatively. Wound complications, intra-abdominal abscesses, and anastomotic leaks and stenosis were recorded. Four types of assessment were performed: bursting pressure, hydroxyproline (OHP) content, histopathology, and biochemical analysis. RESULTS: Compared to the control group, the RSV-treated rats displayed a higher bursting pressure (p < .001) and anastomotic OHP content (p < .05)]. RSV treatment leads to significant increase in PON activity at both time points and decrease in malondialdehyde levels on postoperative day 3 (p < .001). Histopathological analysis revealed that RSV administration leads to a better anastomotic healing in terms of mucosal ischemia, neovascularization, reepithelialization, fibroblast, and lymphocyte infiltration. CONCLUSION: The study results suggest that exogenous RSV administration exerts a positive effect on experimental colonic wound healing in the rat. Although the precise cellular mechanisms by which RSV enhances anastomotic wound healing is not clear, stimulation of neovascularization, generation of collagen synthesis, inhibition of over inflammation, and restriction of oxidative injury seems to be of paramount importance.

RESUMO

BACKGROUND: Simvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor commonly known as a cholesterol-lowering drug with additional pleiotropic effects. Also, it is demonstrated that it prevents postoperative peritoneal adhesions in rat. This study was designed to assess its effects on the healing process of colonic anastomosis. METHODS: Thirty-two male Wistar albino rats were randomized into two groups and subjected to colonic anastomosis. The study group was treated with simvastatin and the control group received only tap water instead. The rats were killed 3 and 7 days postoperatively. Wound complications, intra-abdominal abscesses, and anastomotic leaks and stenosis were recorded. Four types of assessment were performed: bursting pressure, hydroxyproline content, histopathology, and biochemical analysis. RESULTS: Compared to the control group, simvastatin-treated rats displayed a higher bursting pressure (p < 0.001) and anastomotic hydroxyproline content (p < 0.05). Simvastatin treatment leads to a significant decrease in malondealdehyde levels (p < 0.05) and increase in paraoxonase activity (p < 0.001) at both time points. Histopathological analysis revealed that simvastatin administration leads to a better anastomotic healing in terms of reepithelialization, decreased granuloma formation, reduced ischemic necrosis, and inflammatory infiltration to muscle layer. CONCLUSION: Clinically relevant doses of simvastatin do not have a negative impact on colonic anastomosis but improve intestinal wound healing in rats.

RESUMO

INTRODUCTION: Mounting evidence suggests that impaired wound healing is a well-defined consequence in obstructive jaundice and, as redox-regulated processes are relevant to wound healing, it is not unreasonable to suppose that oxidative stress associated with lipid peroxidation in cholestasis might be a systemic phenomenon probably comprising all tissues and organs, including wounds. The aim of the present investigation was to analyse the lipid peroxidation status of surgical wounds, in terms of oxidized low-density-lipoprotein (oxLDL) accumulation in experimental obstructive jaundice. METHODS: Sixteen Wistar-Albino rats weighing 200-230 gr were randomly divided into two groups. Group I (n = 8) was designed as the prolonged obstructive jaundice group and was subjected to bile duct ligation. Group II (Sham-control, n = 8) rats underwent laparotomy alone and bile duct was just dissected from the surrounding tissue. Histopathological evaluation, immunohistochemical screening and immunoflourescent staining of the surgical wound was conducted to the bile-duct ligated rats and control group on the 21st postoperative day. RESULTS: Wound healing was found to be impaired in jaundiced rats histopathologically. When compared with the control group, significant positive oxLDL staining and intracellular accumulation of TNF-alpha, IL-2 and IL-6 was detected in the wound sections of the prolonged obstructive jaundice group. CONCLUSION: Our present data is the first in the literature, indicating significant oxLDL accumulation in surgical wounds of cholestatic rats, which might be one of the results of systemic oxidative stress leading to deficient healing capacity as a consequence of persistent inflammation.

RESUMO

OBJECTIVE: The aim of this study was to assess the factors that might predict patients at increased risk for inadvertent parathyroidectomy and postoperative symptomatic hypocalcemia during thyroidectomy. METHODS: Demographic data as well as the data on preoperative diagnosis, preoperative ultrasonography reports, operation reports, histological findings, and postoperative symptomatic hypocalcemia were collected. A total of 273 (83 male and 190 female patients) thyroid operations were included in this study. RESULTS: Histopathological examination identified inadvertent parathyroidectomy in 10 (3.7%) cases. Statistical analysis identified the presence of cervical lymphadenopathy as detected by preoperative ultrasonography as a risk factor for inadvertent parathyroidectomy. In 57 patients (20.9%) clinically symptomatic postoperative hypocalcemia was observed. However, the difference in the frequency of such hypocalcemia between the patients with and without inadvertent parathyroidectomy was not significant. Statistical evaluation identified total thyroidectomy as a risk factor for postoperative hypocalcemia (p<0.005). CONCLUSION: Due to our experience, inadvertent parathyroidectomy is not a rare entity during thyroidectomy and the presence of cervical lymphadenopathy, as observed by preoperative ultrasonography, is the only risk factor for inadvertent parathyroidectomy. In contrast, no association between inadvertent parathyroidectomy and postoperative hypocalcemia was detected. Total thyroidectomy was found to be the sole risk factor for symptomatic temporary hypocalcemia.

RESUMO

BACKGROUND: There is an ongoing need, from both the medical and the economic perspective, for a more accurate definition of the influence of symptomatic or asymptomatic gallstone disease on gastrointestinal symptomatology, as well as on the health of the individual in general. METHODS: Using the Gastrointestinal Quality of Life Index (GIQLI), 37 symptomatic and 30 asymptomatic gallstone patients were evaluated at admission to the hospital and again 4 months after undergoing an uneventful laparoscopic cholecystectomy (LC). RESULTS: Postoperatively, significant increases in the total GIQLI score were noted in both the symptomatic group (113.42 +/- 21.9 vs 80.32 +/- 19.1 preoperatively; p < 0.05) and the asymptomatic group (96.37 +/- 14.26 vs 113.30 +/- 15.22; p < 0.05). For the subgroups of items, the core symptoms and the physical, psychological, and disease-specific items improved significantly in both groups in the postoperative period (p < 0.05 for all comparisons), but only the symptomatic group achieved a significant improvement in the subgroup of social items (p < 0.05). Negative correlations were found in both the symptomatic and asymptomatic groups between the preoperative GIQLI scores and the improvement seen after LC (r = -0.70 and r = -0.49, respectively). CONCLUSION: Gallstone disease has a profoundly negative impact on quality of life, especially in symptomatic patients with a history of biliary colic attacks and/or the complications of the disease. Although the condition is not equally distressing for the asymptomatic group of patients without such a history, uncomplicated LC improves the quality of life significantly in both groups. Gallstone patients with lower GIQLI scores are more likely to benefit from LC.
