[Intraoperative ultrasonography of the liver].

INTRODUCTION: In many centers specialized in hepatobiliary surgery intraoperative sonography (IOUS) has become a mandatory intraoperative diagnostic tool for intraoperative decision making. We have started applying this technique during liver recections and operations for cancer of the colon in 1988. This presentation is a retrospective report on the first author's personal experience with this technique. PATIENTS AND METHODS: Ninety-two patients were examined intraoperatively, either at Zürich University Hospital or Groote Schuur Hospital in Cape Town. There were 37 female and 55 male patients aged 21 to 84 years (average: 56 yrs). Thirteen patients had primary malignanctes of the liver (group 1) and37 patients underwent IOUS during liver resection for secondary liver tumors (group 2). 14 patients were scanned during operation for benign lesions of the bile ducts and liver (group 3). 28 patients were screened for metastases during resection of gastrointestinal cancers (group 4). The equipment consisted of an Aloka Echocamera SSD 630 and a T-shaped 5 MHz small part in Zürich and a Siemens SI 400 unit with a similar scanner in Cape Town. RESULTS: In group 1 IOUS demonstrated additional information in 9 patients and changed operational procedure in 7 cases. In group 2 IOUS improved on preoperative imaging in 17 cases and changed the approach in 14. Seven patients with benign lesions profitted from IOUS. Additional information changing surgical procedure was gained by IOUS in 6 patients of group 4. CONCLUSIONS: IOUS is a valuable intraoperative imaging technique which is easily performed by the surgeon himself. It should be part of every operation for cancer of the colon and every resection of the liver.

Perforated gastric ulcers: resection compared with simple closure.

One hundred thirty-four patients with perforated gastric ulcers who underwent emergency surgery at a tertiary referral center during a 20-year period were reviewed. Short-term outcome of 94 patients whose perforation was simply closed was compared with 40 who had a gastrectomy. Morbidity (simple closure 51%; resection 45%) and mortality (simple closure 10.6%; resection 7.5%) were similar, but four deaths after simple closure were procedure-related. In patients older than 65 years, morbidity (67%) and mortality (24%) increased significantly. The higher mortality in the elderly was particularly apparent after simple closure (29% vs 11%), but this may reflect selection bias. Simple closure is safe and effective in the majority of patients with perforated gastric ulcers. However, our data indicate that gastrectomy can be performed safely even in high risk cases and should be considered where there is a well documented history of chronicity or when the nature of the ulcer, or associated ulcer hemorrhage, preclude safe simple closure.
