Proximal segmentation of the dorsal mesogastrium reveals new anatomical implications for laparoscopic surgery.

ABSTRACT: Generally, the gold standard of radical surgery for gastrointestinal (GI) tumors is en bloc resection of primary lesions and their related tissues. For gastric cancer, the ideal surgical treatment should be D2 radical gastrectomy plus complete mesogastrium excision. Complete mesogastrium excision is rarely done or mentioned since little is known about the mesogastrium and its presence is still with controversy. Topographically, the "mesogastrium" refers to a peri-gastric structure composed of "fascia propria", enveloping lymph nodes, blood vessels and adipose tissues, which by connecting to the stomach, suspends from the posterior abdominal wall. In this study, by employing video laparoscopy, a number of proximal segments of dorsal mesogastrium were found being extensively scattered around the pancreas. The structure of the mesogastrium was further identified intraoperatively and then confirmed both grossly and histologically after the operation. Our results demonstrated the existence of mesogastrium (gastric mesentery) and its architecture. We suggest for the first time a "Table model" to describe the relationship between the stomach and gastric mesenteries enveloped by fascia propria, which might provide an improvement in the surgical methods for excision of gastric cancer.

Project description:Fast-track surgery (FTS), a multimodal rehabilitation technique, has been recommended as surgical therapy for colorectal cancer. The objective of the present study was to compare the outcomes of FTS and conventional laparoscopic surgery. This study was a blinded randomized trial. A total of 70 patients with colorectal cancer were divided into two groups and underwent laparoscopic colorectal resection. The FTS group consisted of 31 patients and the control group consisted of 39 patients. Protocols for the treatment of the FTS group included skipping pre-operative mechanical bowel preparation, early restoration of diet and early post-operative ambulation. Outcome measures, length of hospital stay, post-operative surgical stress response [C-reactive protein (CRP)] and post-operative complications were compared between the two groups. The average length of total hospital stay for the FTS and the control groups was 5.9±0.8 and 10.9±1.3 days, respectively (P<0.05), and the length of post-operative hospital stay for the FTS and control group was 4.3±0.8 and 8.0±1.1 days, respectively. (P<0.05) First flatus time for the FTS and control groups was 1.6±0.8 and 2.5±0.9 days, respectively (P<0.05). Defecation time for the FTS and control groups was 2.2±0.7 and 4.5±0.7 days, respectively (P<0.05). The time to restoration of a solid diet also showed a significant difference between the FTS and control groups (1.1±0.3 vs. 3.6±0.9 days; P<0.05). Following surgery, due to post-operative surgical stress, the two groups CRP levels increased significantly, but the levels of the FTS group were lower than those of the conventional control group (P<0.05). There was no difference in post-operative complications between the FTS and control groups. This study confirms that FTS shortens hospital stay and accelerates the recovery of bowel function without increase of post-operative complications. FTS is safe, improves post-operative recovery and is a better option than conventional laparoscopic surgery for treating colorectal cancer patients.
