“…Furthermore, an additional explanation of our results might be linked to the omentum anatomy. Specifically, the lesser omentum widely connects to the stomach wall from the anterior side to the posterior side [20][21][22]. Because almost all of lymphatic flows go through the lesser omentum directly at the lesser curvature, the lymphatic basin might be easily influenced by ESD.…”

Background and study aim Standard gastrectomy with lymphadenectomy is recommended following endoscopic submucosal dissection (ESD) due to the risk of lymph-node metastasis for resected cancers. However, when lymphatic flows remain unchanged after ESD, a minimally invasive function-preserving surgery based on the sentinel node (SN) concept may be applicable. In this study, using porcine survival models, we aimed to investigate whether gastric lymphatic flows were modified following ESD. Methods Twelve pigs, each with one simulating lesion 3 cm in size, were used. Indocyanine green (ICG) fluid was endoscopically injected into the submucosa in four quadrants surrounding the lesion. Following laparoscopic observation of lymphatic flows, the lesions were resected by ESD. After 4 weeks, ICG fluid was injected in four quadrants surrounding the scar and lymphatic flows were observed in the same manner as the initial procedure. The distribution of lymphatic flows, including stained SNs, was compared. Results In ten lesions (83.3%), the distribution of flows remained unchanged. However, in one lesion, the flow along the right gastric epiploic artery (R-GEA) disappeared on the lesser curvature of the middle stomach. In addition, in one lesion, the flow along R-GEA emerged on the lesser curvature of the lower stomach. Conclusions Our study revealed that, despite ESD, lymphatic flows remained unchanged in most parts of the stomach. The SN concept may be applied after ESD, except for lesions on the lesser curvature. However, in the case of the lesser curvature, special care must be given to the SN concept.

“…In contrast to the configuration in companion animals, the deep and superficial leaves of the bursal portion of the 36,37 and the greater omentum is attached to the transverse colon, 30 which is not the case in dogs. 38 Furthermore, in people the main omental blood supply is derived from the gastroepiploic arteries. In contrast, as confirmed in the present study, the main vascular supply in dogs is not derived from the marginal omental vessels.…”

“…The omentum, a part of the peritoneum, is divided into the greater and lesser omentum; it extends from the stomach to the urinary bladder and covers the intestinal loops ventrally and laterally 1 2. In the dog, the omentum comprises bursal, splenic and veil parts and main blood vessels originate from the gastroepiploic arterial arch and from branches of the splenic artery 2. The gastrosplenic is the broadest ligament of the omentum, which extends from the splenic hilum to the greater curvature of the stomach 1.…”

A 5-year-old female spayed Cane Corso was referred for further investigation and treatment of a splenic torsion and an abdominal mass. The dog presented with a history of anorexia, depression and vomiting of 4 days’ duration. Physical examination revealed pain on abdominal palpation. On a plain radiograph of the abdomen, a cranial abdominal mass and splenomegaly were present. On CT images of the abdomen, a twisted splenic pedicle, splenic torsion and a well-defined mass in the left cranial abdomen were observed adjacent and caudal to the greater curvature of the stomach. The dog underwent a midline coeliotomy, a total splenectomy and a partial gastrectomy to resect the mass attached to the great curvature of the stomach. Omental torsion was diagnosed on gross and histological examinations of the mass. The dog was reported by the owners to be free of clinical signs 2 years after surgery.
