Intra-abdominal surgery in patients with advanced cirrhosis

Between 1971 and 1984, intra-abdominal surgical procedures were required in 51 patients with cirrhosis who had advanced liver dysfunction and/or ascites. These included the following types of surgery: gastric, 17 patients; small bowel, two patients; colon, five patients; hepatic, nine patients; and pancreas, nine patients. Twelve patients also underwent exploratory celiotomy for an acute condition of the abdomen (six patients) and jaundice (six patients). Patients fell into two groups: (1) those with prothrombin time (PT) greater than 2.5 s over control (24 patients), and (2) those with PT within 2.5 s of control (27 patients). The 30-day mortality rate was 34 (67%) of 51 patients. Nineteen (83%) of 23 patients who had ascites died. Twenty-two (91%) of 24 patients with elevated PT greater than 2.5 s of control died. Twenty-five (86%) of 29 patients who underwent surgery under emergency conditions died. Intraabdominal surgery in decompensated patients with cirrhosis must be undertaken with great caution.     

Radiologic diagnosis of an intra-abdominal abscess. Do multiple tests help?

A review was made of the charts of 94 patients who underwent ultrasonography (US), computed tomography (CT), and gallium citrate Ga 67 (Gall) scan to rule out intra-abdominal abscesses. Of all the clinical and laboratory data, only the presence of pain and tenderness differentiated patients with and without abscesses. A review of radiologic data showed that CT was superior to US, and that US was superior to Gall scan with regard to sensitivity, specificity, accuracy, and positive and negative predictive values. When multiple radiologic tests were performed, results agreed in 72% of cases; therefore, the additional tests were essentially redundant. When radiologic test results disagreed, accuracy rates were CT, 0.86; US, 0.00; and Gall scan, 0.44. These findings suggest that, except to rule out pelvic abscesses in the presence of pelvic inflammatory disease, CT is usually the only special radiologic test that should be performed to localize a suspected intra-abdominal abscess.     

Surgical margins after needle-localization breast biopsy

: The use of needle-localization breast biopsy (NLBB) for the early diagnosis of breast cancer is common. The therapeutic adequacy of tumor-free margins following NLBB is unknown. We hypothesized that the presence of residual tumor after reexcision (mastectomy, tylectomy, or quadrantectomy) does not depend on the margin status following NLBB. : Retrospective cohort analysis was performed on 890 consecutive NLBBs executed between January 1990 and June 1994. Patients with invasive breast neoplasia were divided into two groups based on the tumor margins after NLBB. Group 1 were the women with positive margins, and group 2 had negative margins. Breast specimens after reexcision were reviewed for evidence of residual invasive carcinoma. : Invasive neoplasia was present in 107 patients (12%). Surgical margins and definitive records of care were avaliable for 96 of them (90%). All 45 patients in group 1 and 38 (75%) of 51 patients in group 2 underwent reexcision of the initial biopsy site (P = 0.36). Residual invasive carcinoma was present in 10 patients (22%) in group 1 and 3 (8%) in group 2 (P = 0.13). : Invasive breast neoplasia diagnosed by NLBB requires reexcision regardless of tumor margins to achieve complete local surgical eradication of tumor.
