[The idopathic granulomatous mastitis. ].

Two cases of idiopathic granolomatous mastitis were diagnosed by histological examination in our Surgical Department in 2017. The idiopathic granulomatous mastitis is a rare, benign inflammatory laesion of the breast which can mimic malignancy in it's clinical appearance. We would like to draw attention to this differential diagnostic problem based on the cases of our Surgery Department.

[Guidance for transanal operations].

We summarized diagnostic, surgical treatment and follow-up principles of benign and early malignant lesions of the rectum. Our aim is to provide a nationwide practical synopsis of transanal minimally invasive surgical techniques which might be the basis of a Hungarian national audit of rectal polyp management.

[Minimal invasive esophageal resection with anastomosis on the neck [McKeown]. Our experiences after 20 cases].

Objective: Esophageal resection is a traumatic intervention usually performed on patients with poor condition, resulting high mortality and morbidity. To improve the high incidence of complications, minimal invasive interventions were introduced. The results of the thoracoscopically and laparoscopically performed esophageal resection (McKeown) was investigated after 20 cases and the technical details of the surgical intervention are presented.

[Our metabolic surgical activity, 2010-2016].

Introduction: The prevalence of morbid obesity and its co-morbidities - first of all diabetes type 2 - increased dramatically in the last decades. As the conservative ways of treatment (diet, training, etc.) in most cases does not lead to effective and long term weight loss, there is an increasing need for the metabolic surgical interventions.

[Our experiences with the use of 3-dimensional meshes to prevent and to repair parastomal hernias].

Introduction: Albeit there is decreasing tendency nowadays for stoma construction, if it still happens, parastomal herniation might occur in up to 50% of cases afterwards. One third of the cases requires surgical correction, not rarely as an emergency. The different methods of repair can be quite demanding and the complication rates are high.

[Proctocolectomy with J pouch. Ileo-anal anastomosis performed with PPH stapler. Our experiences after 88 cases].

Aim: Ulcerative colitis (CU) or Familiar Polyposis (FAP) can be the indication for proctocolectomy reconstructed with J pouch. The complete removal of the colon mucosa is essential regarding the late complications and at the same time the atraumatic surgical technique is very important concerning on the long term functional results. Both aspects seems to be answered by the stapled ileo-anal anastomosis using a "procedure for prolaps and haemorrhoids (PPH)" stapler applied by us since 2000.

[Retrospective analysis of carcinomas of the rectum operated by TEM during one year at our institute].

Introduction: The very first TEM (transanal endoscopyc microsurgery) in Hungary was performed in our department by professor Attila Nagy in 1992. Up to August 2016, 1385 operation in total was performed with an average number of 60 per year., 992 operations were carried out for benign reasons and 393 cases for malignancies.

Quality of life, weight loss and improvement of co-morbidities after primary and revisional laparoscopic roux Y gastric bypass procedure-comparative match pair study.

Background: The prevalence of morbid obesity and its co-morbidities is dramatically increasing, as is the extent of weight loss surgery. A large number of patients after various bariatric procedures need revisional intervention for various reasons. We investigated the efficacy and the safety of revisional laparoscopic Roux Y gastric bypass (LRYGB) among our patients, who were revised as a consequence of inadequate weight loss or weight regain after previous bariatric interventions.

[Reconstruction of soft tissue defect of the sole using an ALT flap].

Soft tissue defect of the sole is usually a quite challenging problem. In this case report the most frequently used reconstructive options of this problem are reviewed paying particular attention for the well applicable and reliable types. An ALT graft as a free flap to the sole offers a good possibility for coverage, which is resistant enough to mechanic strains.

[Parastomal hernias].

The overall incidence of parastomal hernias is 35-50%. Different methods of hernia repairs (local fascial repair, stoma relocation and various types of mesh repairs) did not provide satisfactory results. Laparoscopic approach makes peristomal incision unnecessary and decreases the potential risk of mesh infection as well.
