Gastrectomy

PURPOSE: To evaluate the usefulness of prone pad study in upper gastrointestinal series(UGIS) for thedetection of early gastric cancer(EGC). MATERIALS AND METHODS: During an eight-month period, 88 of 170 patientswho underwent gastrectomy due to EGC were also the subjects of prone pad study as well as double contrast(n=92),mucosal relief(n=76), or compression(n=91) studies. The EGCs were single in 84 patients and double in four. Wecompared prone pad study with the three other techniques for detecting a tumor and depicting the surroundingmucosal changes. Lesional conspicuity was rated 'complete', 'incomplete','suspicious'. or 'undetected'. Thedepiction of surrounding mucosal change was rated 'excellent', 'good', 'fair', or 'poor'. RESULTS: Mean tumorsize was 3.2cm, with a range of 0.3-9cm. Tumors were located in the antrum(n=55), angle(n=13), lower or midbody(n=16), or the sign body and cardia(n=5). Among the 92 EGCs evaluated, UGIS missed the lesion in threecases(sensitivity, 97%). The rates of 'complete' lesional conspicuity were 49% inn prone pad, 29% in compression,20% in double contrast, and 9% in mucosal relief. The rates of excellent' in depicting surrounding mucosal changewere 45% in prone pad, 11% in double contrast, 9% in mucosal relief, and 9% in compression. The tumor wasdemonstrated only in prone pad study in five(5%) of the 92 EGCs. CONCLUSION: prone pad study during UGIS improvesboth the detection rate of EGC and the depiction of mucosal change around the tumor.

PURPOSE: Despite knowledge of the adverse effects of resection-line disease, surgeons continue to perform inadequate resections. This demonstrates the need for a more aggressive approach to assessment of resection margins at operation. MATENRIALS AND METHODS: Seven hundred fifteen gastric cancer patients who were operated on at our hospital from 1992 to 1998 were included in this analysis. Various clinico- pathological factors, including resection-line involvement, were ascertained from the surgical and histopathological records. RESULTS: Of the 715 evaluable patients, 27 patients (3.8%) had involvement of one or both resection lines; in 10 patients the proximal resection line only, in 16 the distal resection line only, and 1 both resection lines were involved. Presence of resection-line involvement was significantly associated with T3 and T4 stage, N (+) stage, M (+) stage, type of operation (total gastrectomy), tumor location (entire stomach), size > or =11 cm), and gross type of tumor (Borrmann 4 type). When performing a distal subtotal gastrectomy, no involvement was found when the cranial and caudal distances between the lesion and the line of transection was equal to or greater than 2 cm and 3 cm, respectively, for early cancer and 7 cm and 3 cm, respectively, for advanced cancer. When performing a total gastrectomy for upper 1/3 or middle 1/3 gastric cancer, no involvement was found when the cranial distances between the lesion and the line of transection were equal to or greater than 3 cm and 4cm, respectively, without distinction of the presence of serosal invasion. CONCLUSION: The difference in survival between positive and negative margin patients is limited to the group of patients with curative surgery. An important principle of treatment is that the entire tumor must be removed with a 3 cm distal margin and a 2- to 7 cm margin depending on the location and the depth of wall invasion of the tumor, to provide histologically negative margins.
