BackgroundLow rectal cancer surgery without anus conservation needs permanent ileostomy or colostomy which seriously affects the quality of life of patients. Therefore, low rectal cancer surgery not only pays attention to the safety of surgical treatment but also to the anus conservation.MethodsSixty-seven patients suffering from low rectal cancer had undergone laparoscopic surgery which was analyzed through retrospective study. They were divided into the anus-conserving and non-anus-conserving groups. Thirty-five set of pelvic data was obtained from the preoperative CT and MRI images. After that, the discriminant function was obtained to predict the surgery methods for patients with low rectal carcinoma.ResultsAnal-conserving group discriminant function (F1) = − 33.698 + 6.045 × anal margin distance (cm) + 1.105 × T4; non-anus-conserving group discriminant function (F2) = − 14.125 + 3.138 × anal margin distance (cm) + 0.804 × T4. If F1 is greater than F2, then the case can be treated as the anus reservation while if F2 is greater than F1 the case cannot be treated anus reservation. The accuracy of the discriminant function was evaluated which was found to be 97%.ConclusionThe discriminant function of pelvic data provides anatomical basis for the choice of surgical methods for low rectal cancer.

Background: Spontaneous hemorrhage of gastro-omental hemangioma is a rare disease. Such patients generally have no medical history of recent abdominal trauma, abdominal surgery, anticoagulation or systemic vascular disease. Treatment strategy of this disease variates along with its development. In the acute circumstances, surgery is somehow the first priority. Among them, laparoscopic treatment should be the most frequently considered option in the large general hospital, however, such cases are rarely reported until now.Case presentation: The present report enrolled two cases admitted with upper abdominal pain. Subsequent abdominal computed tomography (CT) scan revealed masses alongside the greater curvature of the stomach. Laparoscopic surgeries were conducted immediately and the postoperative pathological examination suggested ruptured omental hemangioma with thrombosis. Both two patients recovered smoothly after surgery, and no obvious abnormalities were complained in the follow-up period.Conclusions: Clinicians should consider the possibility of spontaneous rupture of gastro-omental hemangioma in patients with abdominal stroke. The center of medical institutions with mature technology and equipment can perform laparoscopic treatment to minimize surgical trauma and promote rapid recovery of the cases with abdominal apoplexy.

BackgroundSpontaneous hemorrhage of gastro-omental hemangioma is a rare disease. The treatment strategy for this disease changes as it develops. In the acute stage, surgery is the first priority, among which laparoscopic treatment should be the most frequently considered option in large general hospitals. Due to the rarity of this disease, such cases have rarely been reported.Case descriptionWe present the first report of two eldely cases with gastro-omental hemangioma with hemorrhage by laparoscopic treatment. Both cases were initially admitted with upper abdominal pain, and abdominal computed tomography (CT) scan revealed masses alongside the greater curvature of the stomach. Laparoscopic surgery was conducted immediately in both patients. The two cases recovered well after surgery, and no obvious abnormalities were observed in the follow-up period.ConclusionGastro-omental hemangioma rupture remains an uncommon cause of intraperitoneal hemorrhage. Timely diagnosis and surgery are paramount for treatment. Medical institutions with the correct technology and equipment should perform laparoscopic treatment to minimize surgical trauma and promote rapid recovery of patients with abdominal apoplexy.
