The association of ectopic pregnancy and acute appendicitis has seldom been discussed in literature. This report presents 2 patients who had simultaneous right tubal pregnancies and acute periappendicitis. The cases reported here suggest the possibility that an ectopic pregnancy can produce an inflammatory reaction of the appendix. Ectopic pregnancy as an etiological stimulus for acute appendicitis is discussed. The advisability of examining the appendix at the time of surgery for pelvic disease, and performing an appendectomy at the same time, if pathology of the appendix is suspected, is emphasized. The use of elective appendectomy in surgery for ectopic pregnancy is reviewed.

The data from a retrospective study of 224 patients with preoperative diagnosis of acute appendicitis are presented. Periappendicitis was subsequently diagnosed in 5.4 per cent of these patients. More than half of these patients with periappendicitis had other intraabdominal disease demonstrable at operation. The remaining patientw with periappendicitis were followed for two years, and long-term complications were not observed. It is concluded that periappendicitis does not represent an unrecognized nonappendiceal process that requires special management.

Periappendicitis has heretofore been regarded as a pathologic curiosity with little clinical significance. In this report, we have reviewed the UCLA experience with periappendicitis. Between 1955 and 1985, resected appendices of 353 patients showed periappendicitis on pathologic examination. Sixty-one of these patients, in whom exploratory surgery was performed for reasons other than acute appendicitis, underwent incidental appendectomy. In 251 of the remaining 292 patients, appendectomy was performed either for pathologically confirmed acute appendicitis or concomitant with treatment of other unsuspected abnormalities discovered intraoperatively. Although the remaining 41 patients were also believed to have acute appendicitis, their resected specimens revealed only periappendicitis. The latter group was composed of 9 males and 32 females, with a mean age of 29 years (range: 6 to 76 years). Twenty-four complications occurred in 18 of these patients (44%). Seven additional operative procedures were required in 5 of the 41 patients (12%). One patient died (2%). We conclude that identification of periappendicitis in the patient presumed to have acute appendicitis is of definite clinical significance and may merit further clinical investigation.

Of a total of 3,669 appendectomies, five corresponded to appendicular diverticulosis (0.13%), all of which had an inflammatory pathology. Four patients underwent emergency surgery with a diagnosis of acute appendicitis, and in only one was a correct preoperative diagnosis made. There were three cases of acute primary diverticulitis and one appendicitis with secondary diverticular affectacion. Another patient was operated electively for a history of long evolution; during the surgical act an appendicular inflammatory mass was found that the pathological report described as diverticulitis with subacute periappendicitis. Certain aspects of this entity are remarked and the bibliography is reviewed.

Periappendicitis, a variant of appendicitis, is histologically diagnosed in only about 5% of appendices removed for presumptive acute appendicitis. We herein describe a boy with periappendicitis whose clinical presentation was that of left renal colic and partial left midureteral obstruction. Appendicitis not infrequently simulates right ureteral colic. However, to our knowledge appendiceal inflammation never has been reported to stimulate left ureteral colic. Also, complications of appendicitis are known to cause right ureteral obstruction (rarely bilateral) but have not been reported to cause solitary left ureteral obstruction. We found no previously reported case of solitary left ureteral obstruction from appendiceal inflammation or of periappendicitis causing a serious urologic complication.

Other pathology besides appendicitis may be found in patients with right lower quadrant pain. This has led some to advocate diagnostic laparoscopy/laparoscopic appendectomy for all such cases. This policy would substantially raise the costs of care without a priori proof of its efficacy. However, a selective approach on when to proceed with diagnostic laparoscopy will depend on the frequency of finding unexpected, nonappendiceal pathology. To determine this, we reviewed our experience with 202 appendectomies. For females < 50 years old, 33 per cent had normal appendices, 12 per cent had periappendicitis, 47 per cent had acute appendicitis, 12 per cent had perforated appendicitis, and 26 per cent had other nonappendiceal pathology. For males < 50 years old, 13 per cent had normal appendices, 8 per cent had periappendicitis, 67 per cent had acute appendicitis, 15 per cent had perforated appendicitis, and 5 per cent had other pathology. For patients > 50 years old, 7 per cent had normal appendices, 13 per cent had periappendicitis, 33 per cent had acute appendicitis, 60 per cent had perforated appendicitis, and 20 per cent other pathology. Other nonappendiceal pathology was found in 42 per cent of females < 50 with normal appendices, 57 per cent with periappendicitis, and 14 per cent with acute/perforated appendicitis. In males < 50 years, 50 per cent of those with normal appendices, 10 per cent of those with periappendicitis, and 0.7 per cent of those with acute appendicitis had nonappendiceal pathology. In conclusion, women of childbearing age and patients > 50 years old have a significant incidence of nonappendiceal pathology. In this group of patients, a diagnostic laparoscopy appears justifiable to identify the cause of the abdominal pain.

Although acute appendicitis is frequent, it is subject to common misconceptions. Furthermore, there is little good evidence to support some of our beliefs. This report reviews the role of the anatomic pathologist in diagnosis when acute appendicitis is suspected clinically and discusses what is known of its pathology. The conclusions that can be legitimately drawn from the literature are emphasized. A classification is proposed that incorporates intraluminal inflammation, acute mucosal inflammation, acute mucosal and submucosal inflammation, suppurative (phlegmonous) appendicitis, gangrenous appendicitis, and periappendicitis, and the significance of each of these diagnoses is discussed. The etiology and pathogenesis of acute appendicitis is reviewed. Contrary to popular belief, the best evidence indicates that obstruction is unlikely to be the primary cause, at least in the majority of cases. Ancillary techniques in the diagnosis of appendicitis, including laparoscopy and peritoneal aspiration cytology, are discussed.

Between September 1994 and February 1997, 30 patients with clinical diagnosis of acute appendicitis were subject of laparoscopic appendectomy (LA) at the "Stella Maris" Clinic in Lima - Peru. Only one conversion to an open procedure was practiced to a 69 years old woman with an appendiculate plastron. Out of the other 29 LA cases, 17 were women (58.6%) and 12 were men (41.4%) with an average age of 23 years, average surgery time of 94 minutes, average time of restablishment of food in-take 15 hr. and average post-operation time of hospitalization 27,1 hr. The anatomo-pathologic diagnosis revealed 11 cases of acute appendicitis, 1 case of suppurative acute appendicitis, 6 cases of acute appendicitis + peritonitis, 1 case of chronic periappendicitis, 6 cases of vascular congestion and/or follicular hyperplasia. There were also reported 3 cases of vascular congestion and/or follicular hyperplasia associated to gynecological pathologies that were solved laparoscopycally. A minor wound infection was registered as a post-operative complication. Thus, it is concluded that the LA is a save method of low morbidity, applicable to children, very advantageous in women in fertile age, in obese or fat patients, in the cases of diagnostic doubt and in patients with complicated appendicitis.

The aim of this study was to identify clinical parameters that may help distinguish periappendicitis from the more common clinical entity of acute appendicitis. Serosal inflammation of the appendix without mucosal involvement constitutes the condition known as periappendicitis. In most situations this is a sequel of extra-appendicular sepsis and is likely to benefit from treatment targeted to the underlying pathology. But the majority of these cases are initially treated for acute appendicitis as clinical distinction between the two conditions is difficult. In this study some commonly used clinical yardsticks have been analyzed with respect to their value in this subtle diagnosis. We reviewed 231 successive cases clinically diagnosed as acute appendicitis; of these 18 had histologically demonstrated periappendicitis. Eight parameters were studied: age, gender, temperature, white blood cell count, location and duration of pain, associated symptoms, and peritoneal signs. Significant statistical differences were found between the two groups with regard to pain location, pain duration, and the presence of peritoneal signs. It may be possible to suspect periappendicitis preoperatively with meticulous clinical assessment. This may be of value in avoiding missed nonappendicular pathologies.

Acute appendicitis represents one of the most common inflammatory diseases of the gastrointestinal tract. Acute appendicitis is most frequently based on the coincidence of obstruction, reduced blood supply, ischemic damage of the mucosa, and bacterial infection. Inflammation at other abdominal sites may also involve the appendix in 7% of cases causing periappendicitis. In 15-20% there are no pathologic findings of acute inflammation but rather post-inflammatory residues and a neuroma-like proliferation of Schwann cells, typically found in neurogenic appendicopathy. This finding may in part explain the clinical symptoms.
