[Subtotal or total colectomy as surgical treatment of left-sided occlusive colon cancer]. / Place de la colectomie subtotale ou totale dans le traitement en urgence des cancers du côlon gauche et du sigmoïde en occlusion.

INTRODUCTION: The treatment of acutely obstructed carcinoma of the left colon and sigmoid still represents a matter of controversy. The aim of this study was to assess retrospectively the results of its management by emergency subtotal or total colectomy with primary anastomosis. MATERIALS AND RESULTS: Sixty-seven patients were reviewed. There were 42 males and 25 females. The mean age was 70.5 years (range: 26-87 years). Mean operative time was 210 minutes. There were five synchronous colon carcinomas (7.5%) and 23 (343%) synchronous tubulous and tubulo-villous adenomas. No death was noted in the series. Ten postoperative complications (15%) occurred in nine patients including one postoperative peritonitis without evidence of anastomotic leak, one alithiasic cholecystitis, one evisceration and two intra-abdominal abscesses. The mean hospital stay was 11.4 days. Fifty-eight patients were assessed at three and twelve months for functional results. No fecal incontinence was encountered. The mean number of bowel movements per 24 hours was 3.2 at three months and 2 at twelve months. All patients were satisfied with their quality of life. Twelve patients (20.7%) occasionally needed anti-diarrheic medications. CONCLUSION: Urgent subtotal or total colectomy with primary anastomosis is a safe and efficient procedure in the management of acutely obstructed neoplasm of the left colon. It allows to treat in one stage the cancer and the obstruction, bearing no mortality, acceptable morbidity and satisfactory postoperative functional results.

Use of fine-needle aspiration cytology and frozen section in the management of nodular goiters.

BACKGROUND: This study evaluates the role of frozen section (FS) in surgical decisions for nodular thyroid disease when a preoperative fine-needle aspiration cytology (FNAC) is available. MATERIAL AND METHOD: The charts of 113 patients who underwent thyroidectomy for nodular goiter were reviewed. Each patient underwent FNAC, FS, or both. Results were compared with the final pathologic examination to evaluate their effectiveness in predicting malignancy. RESULTS: The sensitivity and specificity of FNAC alone (49 patients) were 73% and 93.5%, respectively, and of FS (111 patients) 68% and 99%, respectively. The result of fine-needle aspiration cytology was: benign (n = 8), malignant (n = 13), indeterminate (n = 25), and nondiagnostic (n = 3). All cases diagnosed as benign on FNAC were benign on final pathology, but of the six FS performed in these cases, four were benign and two were suspect. Of the 13 FNAC that were interpreted as malignant, 11 and 10 proved to be malignant on final pathology and FS, respectively. The 25 indeterminate cases on FNAC were on final pathology benign (n = 21) and malignant (n = 4) and on frozen section were benign (n = 12), malignant (n = 2), and suspect (n = 11). CONCLUSION: When results of FNAC are interpreted as benign or malignant, FS is of little value, because it does not change the extension of thyroidectomy. FS proved useful in determining the extent of thyroidectomy only when results of the FNAC were suspect or atypical.

Perforation of the rectum and colon during barium enema examination. Report of four cases.

BACKGROUND: The barium enema examination (BEE) is an important diagnostic study and considered to be safe without adverse effects. Perforation of the bowel is rare but is the most frequent complication of BEE and can be life-threatening. STUDY DESIGN: We report four cases of barium extravasation due to BEE treated at our institution, three rectal perforations and one perforation in the descending colon. RESULTS: The four patients underwent surgery because signs of peritonitis developed. Two of them recovered and two died from multiple organ failure. CONCLUSION: Perforation of the colon and rectum during BEE constitutes a surgical emergency in most cases. Prompt recognition and management are vital in decreasing morbidity and mortality.
