Ultrasonography with graded compression was performed in 525 patients with clinical signs of
acute appendicitis
. Of 207 patients with surgically proven appendicitis the inflamed appendix (diameter greater than or equal to 6 mm) had been visualized sonographically in 177 (86 per cent). The score for non-perforated appendicitis (91 per cent) was higher than for perforated appendicitis (55 per cent). Twenty-four patients in whom an inflamed appendix was seen on ultrasonography did not undergo surgery because of rapidly subsiding symptoms ('abortive appendicitis'). Four of these 24 developed recurrent appendicitis warranting surgery. Two underwent elective appendectomy and 18 have remained symptom-free. Of 155 patients with a subsequently confirmed alternative condition, ultrasonography made the correct diagnosis in 140: bacterial ileocaecitis (69), mesenteric lymphadenitis (eight), gynaecological conditions (34), urological conditions (eight), caecal diverticulitis (six), perforated
peptic ulcer
(six), Crohn's disease (two) and miscellaneous conditions (seven). Of 139 patients in whom no definite diagnosis was made ultrasonography showed no abnormalities in 138. In four patients a false positive sonographic diagnosis of appendicitis was made and in two patients with appendicitis an alternative condition was incorrectly diagnosed. During the last 3 years of the study the negative appendicectomy rate was 7 per cent and delay beyond 6 h after admission occurred in only 2 per cent of patients with surgically proven appendicitis. When used to complement the clinical diagnosis ultrasonography improves the diagnostic accuracy and patient management in those suspected of having
acute appendicitis

We are presenting 20 cases of carcinoid tumors of the digestive system. We shall evaluate: age, sex, localization and histopathology, symptomatology, therapeutics and evolution. Appendicular carcinoids were the most frequent: 13 cases. All were chance findings in the histopathological examination of surgically resected appendix in eight
acute appendicitis
and in four laparotomies for other reasons. Histologically the classic pattern predominated, with formation of cellular nidus, with the cells being argentaffin. These characteristics permit classifying them as tumors derived from the embrionary middle intestine. No appendicular carcinoid developed metastasis. The extirpation was always curative, partially due to the small size and to the facility of obstructing the appendicular lumen. Four cases were gastric carcinoids. Their cells grouped forming trabeculas or were arranged irregularly, being negative for argyrophil and argentic tinction (tumors derived from the cephalic intestine). Two of them presented associated
peptic ulcer
(histamine implication). The two remaining ones came for studies related to asthenia, anorexia and weight loss, and in both cases hepatic metastasis without carcinoid syndrome were found. Two less frequent localizations were Meckel's diverticulum and ampulla of Vater. The latter developed hepatic metastasis without carcinoid syndrome. The only carcinoid syndrome was found in a patient who died due to adult respiratory distress without having localized the primary tumor.

In an audit of 1190 emergency admissions with abdominal pain (1166 patients) in a general surgical unit, the diagnosis was non-specific abdominal pain (NSAP) in 415 (35 per cent),
acute appendicitis
in 200 (17 per cent) and intestinal obstruction in 176 (15 per cent). The largest number of admissions occurred in the age groups 10-29 years (31 per cent) and 60-79 years (29 per cent). Surgical operations were performed in 551 patients (47 per cent) and there was a 16 per cent incidence of unnecessary appendicectomy (22 per cent in the age group 20-29 years). Fifty-one deaths resulted in a 30-day hospital mortality rate of 4.4 per cent and a perioperative mortality rate of 8 per cent. The mortality rate increased significantly in patients aged greater than or equal to 60 years, and patients aged 80-89 years had a perioperative mortality rate of 20 per cent. The causes of perioperative death included laparotomy for inoperable disease (28 per cent), ruptured abdominal aortic aneurysm (23 per cent), perforated
peptic ulcer
(16 per cent) and colonic resections (14 per cent). The perioperative mortality rates for ruptured aneurysm and perforated ulcer were 71 and 23 per cent respectively. The duration of inpatient stay increased significantly with the age of the patients, including those with NSAP. The results of the study indicate a need to review the methods of management of ruptured aortic aneurysm and perforated
peptic ulcer
, the methods of diagnosis of appendicitis, particularly in young females, and the factors that determine the duration of stay of patients suffering from NSAP.

Among a variety of acute abdomens, acute torsion of omentum, first reported by Marchett in 1851, is least suspected under the impression of, most commonly,
acute appendicitis
and then acute cholecystitis, mesenteric thrombosis, ovarian cyst, perforated
peptic ulcer
, etc. A 52-years-old woman was admitted on May 2, 1987 with anorexia, nausea and RLQ pain for 2 days. Physical examination revealed tenderness, guarding and rigidity over RLQ. White cell count was 12.100/mm3. A reducible hernia was found in the right inguinal region. The operation through McBurney's incision showed blood-stained fluid. Appendix was slightly congested. A solid, gangrenous mass was palpated at right iliac fossa that disclosed a completely tight torsion of omentum twisting 6 times counterclockwise with distal infarction. Segmental omentectomy, appendectomy and hernioplasty were done. The patient's recovery was uneventful. This case emphasizes the necessity of routine examination of the omentum during the course of abdominal exploration especially when serosanguinous fluid was encountered in the peritoneal cavity.

Spontaneously perforated pyometra is rare, but the condition must be born in mind in women with acute abdomen. Two cases are reported, one resembling perforated
peptic ulcer
, the other was mistaken for
acute appendicitis
.

Acute cholecystitis is a non-rare disease, the incidence of which was increasing in the last years parallel to biliary lithiasis, which in 90% of cases is the first cause of such pathology. From the anatomopathological standpoint, we distinguish three types of acute cholecystitis: catarrhal, suppurative and gangrenous. The most frequently remarked symptom is ache at right hypochondrium. Only in 30% of cases cholecyst can be palpated, in form of ovoid mass; typical is the positiveness of Murphy's manoeuvre; constant is fever, but not subicterus. The introduction of new methods of ascertainment, exempt from any risks, simple to be performed and remarkably careful, made the diagnostics of acute cholecystites easier: parietal cholecystotomography, hepato-biliary scintigraphy, echotomography (first approach investigation), computerized axial tomography and laparoscopy almost always succeed in dispelling doubts. By using more than one of these investigations, a diagnostic accuracy, touching on 100%, can be reached. The differential diagnosis should be placed with:
peptic ulcer
, acute pancreatitis,
acute appendicitis
, gonococcus perihepatitis, virus hepatitis, acute pyelonephritis, right basal pneumonia. The complications an acute cholecystitis can occur are: perforation (localized, in free peritoneum or in a hollow organ), choleperitonaeum, necrosis of hepatic parenchyma, acute pancreatitis. Due to the possible arising of such complications, the mortality unfortunately is not indifferent (5%), especially in patients already weakened by other chronic diseases. Still discussed is the question as to when performing operation. In fact, there are three trends: intervention in immediate emergency, in postponed emergency, or in remote time (preceded by a medical treatment). The Authors prefer the intervention in postponed emergency, as, in their experience, they remarked the poor effectiveness of the delay medical treatment, also involving a greater difficulty in the technical execution of the intervention and a longer stay in hospital. From 1973 up to 1983, 241 cases of acute cholecystitis (158 women and 83 men) were hospitalized at the First Aid Surgical Centre of the Catania University. Eight patients refused the surgical intervention. The remaining 233 underwent, depending upon the seriousness of the affection, the associated diseases and the different reactiveness to the medical treatment, operation: in immediate emergency (26.1%); in postponed emergency (67.8%; in remote time (6.1%). The mortality was 2.2%, with the lowest percentage in the second group.

Irritable bowel syndrome and (or) non complicated diverticulosis, associated with fever, could simulate diverticulitis. Cancer of the sigmoid colon appears the main differential diagnosis, when diverticulitis is associated with an atypical or complete colonic stenosis on opaque enema, with a vesicoenteric fistula or with a peritonitis due to a colonic perforation. Even at laparotomy, a pseudotumoral diverticulitis cannot easily be differentiated from a colonic carcinoma. Acute diverticulitis of the caecum or ascending colon is usually mistaken for
acute appendicitis
. When massive and life-threatening bleeding occurs, the diverticular origin is difficult to assess. Bleeding due to
peptic ulcer disease
and thermometric ulceration being precluded, arteriography performed on emergency is necessary to differentiate between diverticular bleeding and angiodysplasia.

The acute abdomen continues to demand a large proportion of the general surgeon's workload. Recent studies have demonstrated that management errors can be significantly reduced using selective laparoscopy and this should now become routine practice. The continuing advances in laparoscopic surgery that permit many emergency procedures to be performed by this route provide increased impetus for a combined approach using diagnostic and therapeutic laparoscopy for the management of the acute abdomen. Results of current studies must be awaited before the exact role of emergency laparoscopic surgery can be defined, but early reports suggest several advantages in using laparoscopy to manage conditions such as
acute appendicitis
, perforated
peptic ulcer
and gynaecological emergencies.

The purpose of this prospective study was to elucidate the characteristics of adult patients with acute abdomen admitted to a Finnish university hospital. A total of 639 patients entered the study. The most common cause of acute abdomen was non-specific abdominal pain (NSAP) (33.0%) followed by
acute appendicitis
(23.3%) and acute biliary disease (8.8%). The male:female ratio was 47:53 in the whole study population, but there were differences in the age and sex distributions when studied by diagnosis. NSAP was mainly presented in young women, but also in patients over 75 years of age.
Acute appendicitis
was most frequently found in young men, and biliary disease was most common in elderly women. A male predominance was noted in cases of alcoholic pancreatitis and gastritis, renal stones and
peptic ulcer
. Young women and elderly patients were slightly over-represented in the study population when compared with the whole population residing within the study area. 43% of the patients were operated on, and surgery was most common in patients aged 55-64 years and 15-24 years. Altogether 15% of the patients were discharged without hospitalisation. Twelve patients (1.9%) died of various causes, the most common of which was malignancy (four patients). In conclusion, a considerably large proportion (one third) of cases with acute abdomen remained without any specific explanation. Further, age and gender seem to be important factors when the most probable cause of acute abdomen is to be considered. Operative treatment is necessary in almost half of cases, and mortality for acute abdomen is low.

A retrospective analysis of 224 patients was carried out to evaluate the outcome of elderly patients after operation for acute abdominal pain. The mean (+/- SD) age of the patients was 74.6 (+/- 6.4) years (range 65-96) and the male/female ratio was 104/120. The most common causes for an emergency operation were acute biliary disease (26%),
acute appendicitis
(18%), gastrointestinal cancer (11%) and incarcerated hernia (10%). Twenty-nine patients (13%) died during the one-month postoperative period. The most common causes of death were gastrointestinal cancer (24%), ischaemic heart disease (14%) and complicated
peptic ulcer disease
(14%). Ninety-two (41%) patients had non-lethal postoperative complications, the commonest of which were wound infection or dehiscence (28%), urinary tract infection (17%), and paralytic ileus (8%). Ten patients were reoperated on for postoperative complications. The mean hospitalization time was 12.5 days (range 1-99). The results in the analysis of the long-term outcome (mean follow-up time 21 months) revealed that 17% of the primarily survived patients had died. Living patients were satisfied with the treatment and only a few patients were institutionalised after surgery. We conclude that both the short-term and long-term outcome of elderly patients after an emergency abdominal operation is good in benign diseases, and active surgery is justified.
