Ultrasonography has become widely accepted as a diagnostic tool for gastrointestinal diseases. It not only assesses the lumen but more importantly also the wall and the surrounding structures of the stomach and bowel. Furthermore, functional processes (peristalsis, blood flow) can be visualised and provide important information for passage and perfusion. Modern high resolution (compressive) sonography represents an ideal complementary method besides endoscopy for the gastroenterologist. It is used in emergency diagnosis in cases of acute appendicitis and peridiverticulitis. Here sonography is the method of first choice achieving a high sensitivity. The same applies to ileus, which can be diagnosed significantly earlier by sonography than with conventional X-ray methods. Meanwhile sonography can contribute considerable information to clarify pathogenesis (e. g., invagination, intususception). The detection of a perforation depends strongly on the competence of the examiner. The main advantage is the detection of a covered perforation and the genesis (e. g., ulcer). Ultrasound is less commonly considered in celiac sprue but important complementary information can be obtained. Advanced tumours of the gastrointestinal tract can easily be visualised, although early stages can hardly be detected by means of sonography. An accurate T-staging of tumours is not possible with transabdominal sonography, not least because some parts of the bowel (colon and rectum) cannot always and completely be seen. Exclusion of tumour or early detection is not possible by ultrasound. In intestinal diseases additional information besides clinical and endoscopic aspects can be achieved by ultrasound. Sonography is important for differential diagnosis and follow-up and spares the patient from more incriminatory endoscopic operations. Ultrasound is equal to other imaging methods in detecting complications (fistulas, abscess, stenosis). Due to the complexity of the topic the following review will concentrate on giving an idea of the present status of sonography in chronic inflammatory bowel disease, some less frequent intestinal infections (bacterial, pseudomembranous, neutropenic colitis, intestinal tuberculosis), the ischaemic bowel diseases as well as diseases of the upper gastrointestinal tract.

Although laparoscopic appendicectomy has been performed since 1983, the optimal approach for appendicectomy is still under debate. A systematic review and meta-analysis of all randomized controlled trials between 1995 and 2006 was undertaken. Studies were analyzed overall and in 2 subgroups (pre-2000 and post-2000) to examine for changes in outcomes with increased laparoscopic experience. Operation time was significantly longer for laparoscopy and hospital stay was shorter. Operating time reduced markedly for laparoscopy on subgroup analysis. The risks of postoperative ileus and wound infection are lower for laparoscopy. Perhaps paradoxically, the risk of intra-abdominal abscess development is significantly raised with laparoscopy with an odds ratio of 2.26 (P=0.0002). Laparoscopic appendicectomy is a safe and effective method of treating acute appendicitis. This meta-analysis shows improvement in the outcomes of laparoscopy with increasing laparoscopic experience but open surgery appears to still confer benefits, especially in terms of intra-abdominal abscess incidence.

Ultrasound has gained acceptance in the diagnosis of diseases of the gastrointestinal tract beside the classical methods such as endoscopy and X-ray. In a previous publication we discussed the use of ultrasound in emergency diagnostics (e. g., acute appendicitis, diverticulitis/peridiverticulitis, ileus, invagination and perforation) (part 1). Because of the vast extent of this topic, in this overview we will focus on the current role of ultrasound in the detection and assessment of chronic inflammatory bowel diseases, rare forms of colitis (e. g., bacterial, pseudomembranous and neutropenic colitis as well as intestinal tuberculosis), ischaemic bowel diseases as well as diseases of the upper gastrointestinal tract. In chronic inflammatory bowel diseases, ultrasound can give important additional information such as extension, activity, complication (fistula, abscess, stenosis) and in differential diagnosis. It plays an important role in follow-up investigations and can possibly reduce the number of endoscopic examinations. There is still some debate going on about the significance of colour Doppler ultrasound in assessing the activity and differentiation of stenosis. Furthermore, ultrasound is used as a method to guide interventional therapies for abscesses (puncture and drainage). Colour Doppler ultrasound can diagnose ischaemic bowel diseases and also differentiate these from other aetiologies. Ultrasound plays a greater role in the follow-up and assessment of chronic intestinal ischaemia. In the diagnosis of stomach diseases under favourable conditions ultrasound can show changes of the stomach wall, tumours, ulcers and their complication (perforation, penetration) and disturbances of the motility. But an exclusion is not possible.

Results of treatment of 2308 patients, suffering nonincarcerated hernia of abdominal wall of various localization, were analyzed. In 24 (1.1%) of them different pathologic changes of hernial sac were noted and in 17 (0.7%)--the diseases of organs, localized in hernial sac: an acute appendicitis, ileus, trauma, malignant tumor and others. The course of majority of the above-mentioned diseases was masked by incarcerated hernia signs, demanding the urgent operation performance. The operative intervention volume depended on the character of the organ pathological changes, localized in hernial sac, it was directed on the main disease elimination and on the abdominal wall defect closure.

20 patients with the complicated forms of Meckel diverticulum are treated. The nosological forms were: acute diverticulitis (n=16), acute ileus (n=2), intestinal bleeding (n=1) and perforation of diverticular wall with foreign body n=1). All cases were diagnosed only intraoperatively. The majority of patients with the acute diverticulitis presented a clinical picture of an acute appendicitis, on the cause of which they were operated on. Meckel diverticulum was found 40-140 sm from the ileocecal angle. Surgical treatment consisted of the wedge ileal resection and, in 6 patients, appendectomy. There were no deaths.

This study evaluate the need for general practitioners referrals and self referrals of acute abdominal pain patients to emergency surgical service, the appropriateness of GP referral diagnosis and their attitudes dealing with abdominal pain. In three months period all acute abdominal pain patient referrals to our hospital emergency surgical service were audited. Data on final diagnosis, surgical treatment, admission to hospital and surgery performance were recorded. Self referral or GP referral, referring GP diagnosis, referral letters indicating presenting complaint or history, axillar and rectal temperature measurement, laboratory checking and abdominal radiography checking by GP were recorded as well. Also, GPs examination details as palpation, auscultation and digit-rectal checking were recorded. We calculated sensitivity, specificity, positive and negative predictive value (PV) for referring diagnosis. Self referrals and GP referrals differences were evaluated. During the study 318 patients were admitted. A total of 163 (51.25%) referrals were deemed inappropriate; 102 (52.6% of GP referrals) and 61 (49.2% of self referred) (p < 0.05). There were no differences in general treatment, hospital admission and operative treatment in self referred and GP referred groups (p < 0.05 for all three categories). Sensitivity, specificity, positive and negative predictive values for most frequent GP referral diagnoses were: abdominal colic/abdomen in observation 0.78; 0.66; 0.74; 0.70; acute appendicitis 0.37; 0.92; 0.44; 0.90; acute abdomen/peritonitis 0.30; 0.97; 0.54; 0.92; constipation 0.95; 0.98; 0.85; 0.99; and ileus 0.83; 0.97; 0.50; 0.99. Data on GP including clinical examination, patient history and running basic diagnostics were poor. Our results suggest that a general agreement within the profession about what constitutes a necessary hospital referral is necessary. GP consultation quality must be improved by booking more time per patient and by giving more medical/technical attention to patients.

A 44-year-old man with cystic fibrosis with an acute abdomen was hospitalized via the emergency care unit. Additional investigations revealed ileus of the small intestine and an enlarged appendix which suggested acute appendicitis. However, the clinical picture did not fit the diagnosis of appendicitis and therefore the patient was provisionally diagnosed as having a 'distal intestinal obstruction syndrome'. The patient was conservatively treated on this basis and recovered, being discharged in good condition from hospital after four days. An enlarged appendix occurs frequently in patients with cystic fibrosis, so that the appearance of this part of the intestine contributes little to the diagnosis.

The appendectomies for acute appendicitis are the most frequent surgical interventions (43.6%) in our service. The recent studies demonstrated the feasibility and the economical gain of the early oral feeding vs. classic oral feeding, after elective digestive surgery. We wanted to spread these results therefore to the appendectomy for acute appendicitis. It is about a prospective survey carrying on 110 patients also left in two groups, and comparing the classic postoperative oral feeding vs. the early postoperative oral feeding on one year. The two groups were comparable and the studied parameters were : the length of the postoperative ileus, the hospitable morbidity, the length of the hospitalization and the cost of the hold in charge. The length of the postoperative ileus was not different in the two groups as well as the morbidity. The difference of the median length of hospitalization in the two groups was not meaningful. The cost of the hold in charge was meaningfully more elevated in the group with classic postoperative feeding. In conclusion, the early postoperative oral feeding in our survey doesn't reduce the length of the postoperative ileus and don't drag a morbidity anymore that the classic oral feeding. However if it doesn't shorten the length of the hospitalization, it drags a reduction of the cost of the hold in charge. There is a gain therefore precociously to nourish the patients after appendectomy for acute appendicitis.

We present the case of a 58-year old male patient admitted in the surgery section of the University Emergency Hospital of Bucharest and diagnosed with acute abdomen. The minimal clinical-paraclinical investigation (i.e., thorax-pulmonary Xray, biological probes) raises questions as to the differentiated diagnosis and other associated diseases, also suggesting the existence of voluminous diaphragmatic hernia. The CT thorax-abdomen examination confirms the diaphragmatic hernia suspicion, with intra-thorax ascent of the colon up to the anterior C4 level, but does not explain the abdominal suffering; thus we suspected a biliary ileus or acute appendicitis. Medial laparotomy was imperative. Intrasurgically peritonitis was noticed located by gangrenous acute apendicitis, perforated, with coprolite, for which apendictomy and lavage-drainage pf the peritoneal cavity was performed. Post-surgical status: favourable to recovery.

Burkitt's lymphoma is a highly aggressive B-lymphoproliferative disorder. Clinically it most often manifests with extranodal involvement, typically affecting the gastrointestinal tract as a large and rapidly proliferating tumor mass, which may present as acute abdomen. We present a case report of a young man admitted with signs of acute appendicitis. A tumor of the ileocaecal junction was discovered perioperatively and resolved by a right-sided hemicolectomy. Histological examination of the tumor confirmed Burkitt's lymphoma. On the ninth postoperative day, the patient developed signs of ileus and a follow-up CT scan showed tumor masses in the area of the ileotransversoanastomosis. He was transferred to undergo radical adjuvant chemotherapy. Intestinal passage was restored during the next two days. Our aim is to report on the limited role of surgical treatment in this type of malignancy, due to the extremely rapid proliferation of the tumor tissue, when the tumor can grow back to its original size over a period of a few hours or days.
