Abstract:
OBJECTIVETo provide morphological basis for chyle leakage due to operation on upper abdomen or retroperitoneum region.
METHODSThe original part of thoracic duct, cisterna chyle, intestinal trunk, left and right lumbar trunks were examined in 32 adult cadavers.
RESULTS(1) The occurrence rate of cisterna chili was 22% (7 cases), among which 4 cases were oval, 3 cases were triangle. The cisterna chyle was (24 +/- 6) mm in length; the width of middle part was (4.1 +/- 0.9) mm. It was located to the right of midline at the level between the twelfth thoracic vertebral body and the second lumbar vertebral body anteriorly. (2) The original part of thoracic duct was (2.8 +/- 0.7) mm in diameter. The confluence form of thoracic duct included: left lumbar trunk and intestinal trunk united to form the common trunk first, right lumbar trunk then joined the common trunk (9 cases, 36%); right lumbar trunk and intestinal trunk united to form the common trunk first, left lumbar trunk then joined the common trunk (8 cases, 32%); left and right lumbar trunk united to form the common trunk first, intestinal trunk then joined the common trunk (4 cases, 16%); left, right lumbar trunk and intestinal trunk joined together (3 cases, 12%). (3) The intestinal trunk was (36 +/- 15) mm in length. It ascended on the left of descending aorta, superior to the left renal artery, crossed the second lumbar vertebra anteriorly, and joined left or right lumbar trunk to form common trunk, which extended to the cisterna chili or thoracic duct to the right of lumbar vertebra. (4) The lengths of left and right lumbar trunks were (107 +/- 24) mm and (111 +/- 18) mm, the external diameters of origins were (1.7 +/- 0.4) mm and (1.9 +/- 0.4) mm, and the external diameters of terminations were (2.2 +/- 0.6) mm and (2.2 +/- 0.5) mm, respectively.
CONCLUSIONThe larger lymph tubes should be protected emphatically in the relevant region when dissecting the root of celiac and superior mesenteric artery and the termination of inferior mesenteric vein during abdominal operation.
