RESUMO
PURPOSE: Weight reduction can effectively improve nonalcoholic fatty liver disease (NAFLD), which is a constant companion of severe obesity. This study aimed to determine the effect of one-anastomosis gastric bypass (OAGB) on pathological liver changes in severely obese cases with NAFLD. METHODS: The present prospective research comprised 67 subjects with morbid obesity scheduled for OAGB during the period from February 2015 to August 2018. Clinical, biological, and histologic data were evaluated pre and 15 months postoperatively. RESULTS: Fifteen months after surgery, a considerable reduction was noted in the grades of fat deposition, liver cell ballooning, and lobular inflammatory changes, in addition to the total NAS score. Fifteen months after surgery, nonalcoholic steatohepatitis (NASH) disappeared in 42% of the patients. A significant regression of fibrosis stage occurred after surgery in 79.1% of patients (p < 0.001). After surgery, patients had substantial reductions in aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, HbA1c, total cholesterol, and Low-density lipoprotein (p < 0.001, for all comparisons). Diabetes mellitus, hypertension, and dyslipidemia resolved in 54%, 59%, and 69% of the patients, respectively. CONCLUSION: OAGB resolved NASH from nearly 42% of patients and reduced the histological features of NAFLD 15 months after surgery. Bariatric procedures might be adopted as a therapeutic modality in severely obese cases with NAFLD after the failure of lifestyle modifications.

BACKGROUND: Over the past few decades, the rate of Cesarean Section (CS) delivery has been rising rapidly and the prevalence of CS-associated complications including Abdominal Wall Endometriomas (AWE) increases with each additional operation. The aim of this study was to evaluate the clinical characteristics, histopathological diagnostic role and surgical management of post-CS AWE through a retrospective case review. METHODS: We calculated the incidence of AWE and reviewed all the patients underwent surgical removal of Post-CS AWE during the period of 2012-2018 who were diagnosed, treated and followed up for 2-8 years at our tertiary hospital. RESULTS: Thirty women with AWE were included. The main symptom in 2/3 of cases was cyclic pain and 4 cases (13.3%) had no symptoms. The mean interval between prior CS and appearance of symptoms was 55.2 months and the mean size of the excised mass was 42 mm. Free surgical margin was less than 9 mm in 9 patients (30%) but no recurrence was recorded among all the studied patients. Pre-operative FNAC diagnosis was performed for only 3 patients (10%) which helped in excluding other potential pathologies. The clinical-pathological agreement value for detection of the nature of the abdominal wall mass was 93.4%. CONCLUSIONS: Patients with suspected AWE should undergo preoperative cytological biopsy to exclude alternative diagnosis. Wide surgical excision with margin of less than 1 cm could be accepted especially in case of weak abdominal wall. More studies on the post-CS complications; risks, prevention, early detection and proper management should be encouraged.
RESUMO
PURPOSE: This study aimed to assess the potential changes of Growth differentiation factor 15 (GDF15) after laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients. METHODS: We conducted a prospective study on 68 patients who underwent LSG and 58 cases, who were enrolled as a control group, to whom conservative measures of weight loss were adopted. Both groups were followed for 12 months. RESULTS: At the baseline, the serum GDF15 was comparable between LSG and conservative groups (409.93±119 versus 385.8±120.2 pg/mL, p =0.246). However, at 12 months after the operation, the serum GDF15 was significantly higher in the LSG than conservative groups (699.941 ±193.5 versus 559 ±159.7; p <0.001). The degree of serum GDF15 increase was higher in the LSG group (290.01 ±189.9 versus 173.14 ±116.7; p <0.001). The degree of serum GDF15 increase correlated negatively with the final BMI (r = -0.352, p =0.001) and weight loss (r = -0.793, p =0.001) at 12 months after the operation. The correlation analysis demonstrated that the initial GFD15 did not correlate with any baseline parameters. Multiple regression analysis of change in serum GDF15 showed a statistical significance of the weight loss after 12 months. CONCLUSION: The present work confirms the impact of successful weight loss on the circulating level of GDF15. Our study demonstrated that the circulating GDF15 increased significantly after LSG and it was correlated to the degree of weight loss.
RESUMO
INTRODUCTION AND AIM: Recently, the incidence of obesity has been rising exponentially. Clinical studies have demonstrated that different subtypes of pulmonary hypertension (PH) are linked to obesity. The current work mainly aims to assess the impact of laparoscopic sleeve gastrectomy (LSG) on PH in a cohort of obese cases. PATIENTS AND METHODS: The present prospective work included 37 obese cases with PH for whom LSG was done. Only cases with PH and presurgical right ventricular systolic pressure (RVSP) ≥ 35 mmHg using Doppler echocardiogram were enrolled. Fifteen months later, patients were reassessed regarding new weight and BMI in addition to changes in RVSP. RESULTS: At the end of follow-up, the average BMI improved from 45.8 + 3.9 to 33.8 + 2.5 Kg/m2 (p value < 0.001). Improved right ventricular (RV) size compared to baseline echo was observed in 20 patients. RV size decreased from 2.68 + 0.44 cm to 2.34 + 0.36 cm (p value < 0.001). Notable decrease of PH to less than 30 mmHg occurred in 33 patients. Mean RVSP decreased from 39.62 + 2.1 to 31.81 + 3.1 mmHg (p value < 0.001). LSG significantly decreased the requirements for PH drugs and supplemental oxygen therapy. CONCLUSION: The current work suggests that LSG-induced weight loss may result in a considerable decrease in pulmonary pressures as well as RV size with a concurrent resolution of other metabolic comorbidities.

INTRODUCTION: Eccrine poroma is a benign adnexal neoplasm originating from epidermal sweat ducts mainly affecting the palmoplantar skin, buttock as a location of origin of poroma has rarely been reported, it is the first reported case of recurrent poroma in this site. PRESENTATION OF CASE: We report an unusual case of eccrine poroma in the gluteal region of a 62 years old female associated with gluteal abscess, surgically excised with histologically clear margins, then recurred after one and half year with a given history of mild trauma. DISCUSSION: Given the uncommonness of these neoplasms, there stays a general lack of data on pathogenesis, atypical presentation, atypical sites, recurrence and risk of malignant transformation into porocarcinoma. CONCLUSION: Gluteal skin is an unusual location for a benign poroma. Early recognition and appropriate treatment at the initial presentation by complete resection with histopathology confirmation and follow-up are crucial to ruling out other diagnoses, such as lesions of malignant transformation.
