OBJECTIVETo study the optimal surgical resection length for esophageal carcinoma.
METHODSSpecimens of seventy patients with esophageal squamous cell carcinoma resected and collected in our hospital were made into pathologic giant sections. Direct intramural infiltration, multicentric carcinogenic lesion and leaping metastasis were observed in the large slice by microscope. The actual length during the operation was calculated by the ratio of shrinkage.
RESULTSDirect intramural infiltration was found in 51 (72.9%) patients, 39 proximal and 36 distal to the tumor. The mean length of direct intramural infiltration was 0.9 +/- 0.8 cm (4.0 cm maximum) proximally and 0.5 +/- 0.3 cm (2.0 cm maximum) distally. Multicentric carcinogenic lesion was found in 11 (15.7%) patients, 5 proximally, 8 distally and 2 on both sides. Proximal to the tumor, the mean distance between the multicentric carcinogenic lesion and the main lesion plus the length of the multiple carcinogenic lesion was 3.2 +/- 1.5 cm (4.7 cm maximum). Distal to the tumor, it was 3.6 +/- 2.4 cm (9.1 cm maximum). Leaping metastasis was found in 9 (12.9%) patients, 7 proximally and 4 distally. The mean distance between the leaping metastasis and the main lesion plus the length of the leaping metastatic lesion was 1.9 +/- 0.6 cm (2.9 cm maximum) proximally and 1.4 +/- 1.0 cm (2.7 cm in maximum) distally.
CONCLUSIONThe optimal surgical resection length for esophageal carcinoma should be at least 5 cm proximal to the tumor and total length on the distal side.
