[Abdominal tuberculosis].

The authors studied the symptoms, signs and diagnostic procedures in 9 cases of abdominal tuberculosis, six in women, three in men, 17 to 84 and average of 43 years old, who were treated in the Social Security Arnulfo Arias Madrid Hospital Complex in Panama City. In 8 cases the diagnosis was confirmed by biopsy with laparotomy, in 5 with laparoscopy in 1 case because by concomitant lung tuberculosis and improvement with antituberculosis drugs. They present the clinical histories of 2 patients in order to discuss the presenting complaints in abdominal tuberculosis, review the pathology and arouse interest in the study of this entity precisely now that since the initiation of the AIDS epidemic in Panama in 1984 until July 1992 there have been a total of 369 confirmed cases of which 18% had tuberculosis as the first or second opportunistic infection.

[Colorectal cancer. A study of 133 surgical cases].

The author studied the medical records of 133 patients who underwent surgery for adenocarcinoma of the colon or rectum in the Metropolitan Hospital Complex Arnulfo Arias Madrid from June 1972 to July 1992. In 9 (6.7%) the tumor was staged as Dukes A, in 49 (36.8%) as Dukes B; in 60 (43.1%) as Dukes C and in 10 (16.7%) as Dukes D. The anatomical location of the tumor was the cecum in 9 (6.7%), the ascending colon in 3 (2.3%), the sigmoid colon in 44 (33%) and the rectum in 41 (31.6%). Of the rectal carcinomas 24 (58.5%) were in the inferior one third, 10 (24.3) were in the middle and 7 (17%) in the superior third. It is evident that nearly two thirds of the tumors were within reach of the digital rectal examination of the sigmoidoscopic examination. The parents ranged from 21 to 89 years of age and their median age was 63 years. 73 patients were women and 60 were men. 60.5% of the women and 39.5% of the men had carcinoma of the colon. The sexual prevalence of carcinoma of the rectum was different: 5% were in men and 43% were in women. 2.2% of the tumors were synchronous and 4% were metachronous. The author discusses the number, type and indications for the surgical procedures used. There were no perioperative deaths. The 5 year survival for adenocarcinomas of the colon was 100% for those patients with tumors staged as Dukes A, 78.5% for the Dukes B, 61.1% for the Dukes C and 0% for those staged as Dukes D. For the rectal adenocarcinomas the 5 year survival was 100% for those patients with tumors in Stage Dukes A, 57.1%, for those in Dukes B, 33.3 for those in Dukes C and 0% in those in Dukes D. These results indicate that these patients are seen in an advanced stage and point to the urgent need to make the diagnosis in early, curable stages. The low incidence of tumors in stage Dukes A indicates an indifference of the patients and/or the doctors to the symptoms and signs of this disease. The most frequent symptoms, in descending order were: bleeding on defecation (all types), change in bowel habits (diarrhea or constipation), abdominal pains, tenesmus and anemia (with its different clinical manifestations). Other symptoms were a palapable abdominal mass, feces with bloody mucus and rectal prolapse on defecation.(ABSTRACT TRUNCATED AT 400 WORDS)

[Hemorrhoids. Medico-surgical treatment].

The clinical history of 300 patients examined by the author at San Fernando Clinic and 90 consecutive cases operated at CHMCSS were studied. The frequency and characteristics of symptoms, the gender prevalence, the physical findings, the clinical classification and the various therapeutic methods used were determined. It was noticed that 84% of the patients received conservative treatment and 16% were subjected to surgery. The conservative treatment consisted of high fiber diets, warm sits baths, psyllium, hemorrhoidal sclerosis or ligature with rubber bands. The surgical treatment consisted of the ligature and excision of the three primary hemorrhoids and of the hemorrhoidal plexus(5), which is a simple, fast and effective technique, because the removal of the hemorrhoidal cushion avoids recurrences. Furthermore, the suturing of the longitudinal fibers and the pedicle and their fixation to the external sphincter avoids the upward retraction of the pedicle and the formation of denuded areas in the anal canal that can lead to stenosis at the level of the anorectal ring.

[Anal hematoma (coagulated venous saccule or peri-anal thrombosis)].

The Author reviews the clinical histories of eighty patients seen in his private practice with the diagnosis of anal hematoma. He discusses the true nature of "anal hematoma" and points out that it is really a clot in one of the venous sacs of the external hemorrhoidal plexus; and comment the symptomatology and the results of therapy.
