摘要:

&NA;Fine‐needle aspiration biopsy was performed at laparotomy on 15 patients in whose cases differential diagnosis between colonic diverticulitis and colonic cancer on the basis of preoperative and peroperative examinations was impossible. Histologic examination confirmed the cytologic diagnosis to be correct in 14 cases, in four of them correctly positive for tumor cells. There was one false‐negative result. Culture of swabs taken from 11 patients after puncture showed growth of intestinal bacteria in five cases, but no complication developed in association with or after the punctures.Peroperative fine‐needle aspiration biopsy is a cheap, simple, rapid and safe method that seems to offer a reliable aid to differential diagnosis between diverticulitis and carcinoma. With the use of a rapid staining technique, the result can be available as early as that of frozen‐section microscopic examination.

摘要:

&NA;Light and electron microscopic study of a case of multiple granular‐cell tumor of the ascending colon is presented, and the relevant medical literature is reviewed. It seems that the biologic behavior of this tumor in the colon does not differ from that in other locations. Histologically, a few granular cells are seen in neural tissue in the vicinity of the tumor, suggesting a close relation of the tumor to the neural tissue. Electron‐microscopically, the granular cells resemble Schwann cells more closely than neural cells and axons. Histochemically, the granules of the tumor cells show autofluorescence and high activity of acid phosphatase, which was located electron‐microscopically in the limiting membranes and matrices of the granules. It is suggested that the granular‐cell tumor is a neoplasm of Schwann‐cell origin with a unique metabolism that causes acceleration of autophagocytosis and accumulation of ceroidlipofuscin.

摘要:

&NA;Histologic and ultrastructural examination of specimens of rectal mucosa from 11 patients who had recently consumed excessive quantities of alcohol revealed marked pathologic changes. Goblet cells were decreased and a dense mononuclear cell infiltrate was seen on light microscopic study. Electron microscopy revealed swollen, distorted mitochondria and dilated and vesicular endoplasmic reticulum. These abnormalities disappeared after two weeks' abstinence. It is suggested that disordered organelle structure and function might contribute to the diarrhea frequently observed following excessive alcohol intake.

摘要:

&NA;A case of multiple lymphoid polyposis of the colon and terminal ileum occurring in a family of familial polyposis is presented. Only one other such case has been reported. Other cases where an association between the conditions was mentioned are reviewed.There is a genetic factor in the etiology of the condition, and a definite link with familial, polyposis of the colon is found to exist. Differentiation of the conditions on clinical grounds could be very difficult.

摘要:

&NA;On the basis of results in 50 patients undergoing intestinal anastomoses in which monofilament polypropylene suture was used in interrupted single‐layer sutures, it is concluded that this suture material is as good as or better than monofilament surgical steel, and that the method is superior to any two‐layer technique thus far reported. Abdominal wound closures with polypropylene suture shown excellent immediate results. However, enough time has not elapsed to evaluate fully the incidence of incisional hernias. Incistional pain, both immediate and delayed, was much less when polypropylene suture was used.

摘要:

&NA;The clinical courses of 68 patients with obstructive colonic cancers were reviewed. For the majority of patients with an acutely obstructing cancer of the left colon a conventional staged procedure remains the most appropriate treatment. Primary resection is suitable for the more proximal colonic cancer with obstruction. The operative mortality rate was 13.6 per cent, but with the addition of two nonoperative deaths, the figure rises to 16.2 per cent. Only six patients are known to have survived five years.

摘要:

&NA;The distribution by age and sex and the incidence of colorectal carcinomas as seen in this teaching hospital in Bangkok are similar to those reported from western countries. The main differences are that the proportion of patients less than 30 years old is higher the incidence of synchronous tumors is lower, and precancerous lesions are much rarer. Most patients have advanced carcinoma when first seen, which results in a lower resectability rate and poorer expected long‐term survival. The operative mortality rate for resection is low, and comparable to those from other centers.It seems that at least two conditions are necessary for improvement of the outlook of patient with colorectal carcinoma in Thailand. First, there must be wider dissemination of knowledge of the disease process. Second the socioeconomic status of the country as a whole must improve.

摘要:

&NA;Two cases of subcutaneous emphysema of the left lower extremity secondary to perforations of the rectum and sigmoid colon are presented. Although this is an extremely rare syndrome, the true incidence is probably higher, as some cases will be misdiagnosed as gas gangrene unless careful clinical and postmortem examinations are performed.Only rapid recognition of the probable origin of the gas, coupled with aggressive, definitive therapy, can prevent the usually fatal course of this condition.In the absence of trauma to the chest or infection in a previously normal leg, subcutaneous emphysema of a limb should alert the physician to the possibility of a gastrointestinal perforation as a source of the gas. Perforations of the gastrointestinal tract into the subcutaneous tissue can occur anywhere from the neck to the lower extremities.

摘要:

&NA;A case of Crohn's disease of the appendix that simulated a cecal tumor is presented and 27 additional cases are reviewed. Crohn's disease of the appendix most commonly occurs in the younger patient, with 90 per cent in the second and third decades of life. Before operation, appendicitis or an appendiceal abscess is commonly diagnosed. Appendectomy should be performed, if possible; otherwise a limited ileocolectomy should be done. These patients should have a long‐term follow‐up program because inflammation can develop later in any part of the bowel. Crohn's disease of the appendix should be included in the differential diagnosis of pain or a palpable mass in the right lower quadrant, especially in the young adult patient.
