Breast cancer remains one of the most common malignancies in women and is one of the leading causes of cancerrelated mortality. Despite the current emphasis on breast conservation, mastectomy rates remain at 30%. Mastectomy is often associated with significant psychological sequelae including distorted body image and sexual dysfunction. Breast restoration is assumed to allow a full emotional and physical recovery from a breast cancer crisis. Autogenous tissue gives the best results, and currently the best technique in most women is probably the free DIEPflap. there is theoretically minimal functional loss, minimal risk of hernia, less postoperative pain, and shorter hospitalization. However, there is a range of options, such as other flaps and use of implants, which can be tailored to specific situations

The surface area of the small intestine is enhanced by three morphologic features that are peculiar to the gut: plicae circulares, the villi and the microvilli. The plicae circulares (circular folds) consist of mucosal/submucosal invaginations that are predominantly located in the duodenum and jejunum. These infoldings are visible on gross inspection. The intestinal villi, finger-like projections that protrude into the intestinal lumen, are approximately 0,5-1,5 mm long and cover the mucosal surface. They can be viewed by close inspection of the mucosa under low-power microscopy. Their microscopic appearance varies: duodenal villi are characteristically broad and leaf-shaped, jejunal villi are tall and thin, and ileal villi are short and broad. The length and shape of the villi also vary with geographic region. At the base of the villi, the epithelium enters the lamina propria and forms the crypts of Lieberkühn, which extend almost to the muscularis mucosae. The microvilli are sub-light microscopic tubular projections that are extensions of the apical cell membrane and compose the brush border. There are the enzymes and receptors in these structures which are required for terminal digestion and absorption

Chronic appendicitis presents inflammation of appendix with atypical clinical findings, without significant signs
and symptoms. Because of that diagnosing chronic appendicitis presumes a great problem. Indications for operative treatment based on clinical impression are followed with a great number of unnecessary appendectomies. Barium enema can show morphlogic changes of appendix during its chronic inflammation. Our aim was to show values of barium enema in diagnosing chronic appendicitis. Study went prospectively, in period 1999-2001 on Clinic for abdominal and endocrine
surgery, Institute for surgery Novi Sad. It includes 100 patients with symptoms, 50 of them were operated after barium
enema, and other 50 were operated after clinical impression of surgeon. Each appendix was patohistologicaly examined.
Incidental appendectoies were exluded. Of total 1425 appendectomies in three years period, 100 were operatde because of chronic appendicitis. Fifty of them were operated after barium enema, and other 50 were operated after clinical impression of surgeon. Range of years was 15 59 in examined group with average 35,6 years. In control group range was 15 57, with average 32,9 years. Lasting of pain episode more than 12 hours had 94% of patients in examined group, and 72% of patients in control group had painn less than 24 hourrs. During of pain episodes at 92% of patients from examined group was 3 weeks to 12 months, and 86% of patients from control group had pain standing 3-36 weeks. The most common sign on barium enema was finding of coprolites in lumen (52%), followed with unfilled appendix (18%, angulations (10%), distal amputation (8%), segmentation of contrast (8%), and fixated appendix (4%). Intraoperative macroscopic findings were as followed: 40/50 coprolites in lumen, 7/50 fibrous bounds, and 3/50 fibroses of appendix. Patohistologicaly, chronic appendicitis was confirmed at 90% of patients in examined group, and 58% in control group. After surgery, 94% of patients from examined group don't feel the preoperative pain. Barium enema significantly increases of chronic appendicitis. It is non-invasive, and reliable method for showing morphologic changes of chronic appendix. Use of barium enema dereases number of unnecessary appendectomies. Barium enema is suggested for evaluation of patients with chronic pain in right lower quadrant of abdomen, and thereby for diagnosing of chronic appendicitis.
