OBJECTIVES
Ectopic pregnancy is a life-threatening condition; delaying treatment can result in mortality or serious complications. Identification of a biomarker that can predict tubal rupture may be helpful for guiding treatment. In this study, we evaluated the association between serum β-hCG, biochemical markers, Systemic Immunity-inflammation Index (SII) score, and the trophoblastic invasion stage.
MATERIAL AND METHODS
Tubal pregnancy was classified into three groups based on the depth of trophoblastic infiltration: stage I - limited to the mucosa; stage II - invaded the muscular layer, and stage III - invaded the serosa/subserosa of the tuba uterine. The association between groups, serum β-hCG, biochemical markers, and the SII score were assessed.
RESULTS
There was no significant difference between the groups, hemoglobin, platelet count, MPV, RDW, NLR or PLR values (p > 0.05). A ROC analysis was performed to evaluate the accuracy of serum β-hCG predictions for infiltration level. At a 95% confidence interval upper limit, cut-off value of the serum β-hCG that best predicted stage III trophoblastic infiltration, was 2799 mIU/mL, with 78.9% sensitivity, 53.8% specificity (positive predictive value was 71.4%, and a negative predictive value was 63.6%). Moreover, ROC curve analysis showed that The SII value of 792 was the best predictor of trophoblastic infiltration at stage III, with a sensitivity of 92.3% and a specificity of 63.1%.
CONCLUSIONS
A linear relationship exists between depth of trophoblastic infiltration and serum β-hCG and the SII were observed. These findings suggested that the SII score can be used for predicting tubal ectopic pregnancy rupture.

Locally advanced colorectal carcinomas are characterized by neoplastic cells that invade beyond the colon and directly into surrounding organs and structures that include the retroperitoneum and abdominopelvic sidewall. These aggressive tumors are prognostically adverse and are categorized with highest possible tumor stage in current cancer staging systems. Recognizing colorectal carcinoma with extensive locoregional invasion is typically straightforward, but some cases can be diagnostically challenging. These include tumors with limited invasion of extracolonic tissue such as the subserosa in which there are no cells or structures that are histologically or architecturally distinct from the colonic primary. Tumor-associated injury of the colonic peritoneum often precedes invasion by the neoplastic cells and can cause the peritoneal membrane of the colon to adhere and subsequently fuse to the peritoneal membrane of a neighboring organ or structure, thereby creating a trans-peritoneal bridge through which a tumor can directly invade the adherent extracolonic tissue. Hence, locally advanced colorectal carcinoma can be narrowly defined by neoplastic cells that completely invade through the fused peritoneal membrane and into the subserosa of the adherent extracolonic tissue. The evaluation of tumor invasion of the fused peritoneal membrane, which is enhanced by the combined use of an elastic stain and an immunostain for pan-keratin, is essential for the proper staging of locally advanced colorectal carcinoma and its clinical management.

Pneumatosis cystoides intestinalis (PCI) is a rare disease wherein air accumulates in the intestinal subserosa and submucosa, causing multiple gaseous cysts within the gastrointestinal wall. While PCI has various known risk factors, reports identifying muscular diseases as a factor are scarce. The aim of this study is to elucidate the clinical characteristics of PCI in muscle disease. We present a case series of five cases, including two cases of Duchenne muscular dystrophy (DMD) and three cases of rare congenital myopathies. All cases are of male patients, with poor intestinal peristalsis and constipation, who underwent tube feeding and mechanical ventilation via tracheostomy. They had no signs of severe complications, such as intestinal necrosis, and all of them improved with conservative treatment. Case 1 is a 23-year-old man with DMD who developed cardiopulmonary arrest at the age of 20 years. Pulmonary hemorrhage occurred three months before the incidental detection of PCI in the ascending colon, which resolved with conservative oxygen treatment. Case 2 is a 25-year-old man with DMD who progressed to immobility necessitating tracheostomy at the age of 20 years. He experienced persistent abdominal pain and nausea, and PCI was detected in the cecum and ascending colon. He showed near-complete resolution of PCI after three months of conservative treatment. Case 3 is a six-year-old boy with reducing body myopathy. Constipation was diagnosed at four years of age. He experienced intermittent bloody stools, leading to the incidental detection of PCI at six years of age. After two months of conservative treatment, the PCI resolved with no subsequent recurrence. Case 4 is a 33-year-old man with infantile severe myotubular myopathy. He required mechanical ventilation immediately after birth and later underwent tracheostomy and tube feeding due to complications. At the age of 27 years, PCI was incidentally detected on abdominal CT. He had episodes of remission and worsening for a few years; however, PCI completely resolved after three years. Case 5 is a 27-year-old man with nemaline myopathy. At the age of 14 years, he had persistent bloody stools. After lower gastrointestinal endoscopy, he was diagnosed with PCI with numerous rectal cysts. PCI required no specific therapeutic intervention. There was spontaneous resolution of PCI and bloody stools. Given that PCI lacks specific symptoms and cases with muscular diseases often experience abdominal issues, many cases are liable to be overlooked or misdiagnosed. Cases with muscular diseases complaining of persistent abdominal symptoms should undergo radiographic imaging to rule out PCI.

Observational Study
Pneumatosis intestinalis (PI) is a condition in which multiple gas-filled cysts form within the wall of the gastrointestinal tract in either the subserosa or submucosa. The presence of pneumoperitoneum in the presence of PI can present a therapeutic dilemma. The aim of our study was to review our experience and management of this condition. A single-center retrospective study of consecutive children (> 1 year) presenting with a pneumoperitoneum and evidence of PI (2009-2015). Demographics, case notes, microbiology, and imaging were reviewed. Seven patients were identified (four males; age range 5-14 years). Four children had global developmental delay and were percutaneous endoscopic gastrostomy or jejunostomy fed, one was immunocompromised (acute lymphoblastic leukemia). The others had encephalitis and eosinophilic gastroenteritis. One patient proceeded to an exploratory laparotomy; no perforation was identified, pneumatosis of the colon was observed, and a loop ileostomy was formed. The remaining six were managed conservatively and made nil by mouth with intravenous antibiotics commenced. Five of the six had a computed tomography (CT) scan which revealed PI and free air with no other worrying signs. One died from nongastrointestinal causes, while the remaining five had feeds reintroduced uneventfully. Free air in the setting of PI may represent rupture of the gas cysts and not always transmural perforation. Surgery may not always be indicated and conservative management may suffice. A CT scan can be useful for excluding other intra-abdominal pathological findings and continued clinical assessment is essential.

Pneumatosis cystoides intestinalis is a rare and usually benign condition in which multiple thin-walled cysts develop in the submucosa or subserosa of the gastrointestinal tract. While usually asymptomatic, severe cases can result in pneumoperitoneum, which can be managed surgically or medically depending on circumstances. A 35-year-old male patient presented with signs and symptoms of intestinal obstruction. Then the patient was diagnosed with pneumatosis cystoides intestinalis. The patient underwent surgery, and antibiotic treatment, and was discharged improved with no incident. Pneumatosis cystoides intestinalis is a surgical condition that resembles other life-threatening top surgical emergencies and affects clinicians' decisions on diagnosis and treatment plans substantially, mainly in low-income countries. So, surgeons have to consider such kind of conditions and avoid the costs and morbidities associated with unnecessary bowel resection or surgery.

BACKGROUND
Transvaginal natural orifice transluminal endoscopic surgery (NOTES) is a surgical technique - "scarless" abdominal operations performed with a multi-channel endoscope passed through a natural orifice (mouth, urethra, anus, vagina etc.) and offers less invasive and more excellent cosmetic results [1]. It is regarded as safe and feasible in patients with benign disease [2,3]. The first case of pure NOTES for sigmoid colon cancer was reported in 2012 [4]. We describe here a case of curatively intended resection for early-stage sigmoid colon cancer using the hybrid transvaginal NOTES approach.
METHODS
This video demonstrates the case of a 52-year-old woman with sigmoid colon cancer treated by hybrid transvaginal NOTES. Her body mass index was 20.4 kg/m. A laparoscope was inserted above the umbilicus and tumor's position was located. Two 5 mm trocars inserted in the right lower abdominal quadrant were mainly used for the assistant's instruments to provide traction and exposure. A single-port was inserted into the abdominal cavity transvaginally through the colpotomy. Then all the procedures were performed transvaginally with conventional rigid laparoscopic instruments. The sigmoid colon was mobilized using a lateral to medial approach. Then the root of the inferior mesenteric artery and the inferior mesenteric vein were divided with absorbable clips. After complete isolation of the proximal rectum, the rectum was transected 5 cm distal to the lesion with a linear stapler inserted through the single port. The proximal resection margin of descending colon was identified and the transection of the colon was performed. The specimen was removed transvaginally. The colon was then exteriorized and the anvil was fixed in the colon. An end-to-end anastomosis was performed using a circular stapler, and a leak test was done.
RESULTS
The operative time and estimated blood loss were 182 min and 50 mL. A 20 cm long segment of sigmoid colon was resected with negative tumor margins, and 16 lymph nodes were harvested. There was no intraoperative or postoperative morbidity. The patient was with out-of-bed activity on day 1, fluid diet on day 2, bowel movement on day3, and the drainage tube and catheter removing on day 4. On day 5, she was discharged. Pathological examination revealed a moderately-differentiated adenocarcinoma: 50 × 45 × 10 mm, with growing into subserosa, without vascular or nervous invasion, pT3N0M0 and pStage IIA. There were two scars less than 5 mm and one scar less than 10 mm visible on the abdominal wall at one month. The patient was alive without recurrence after one year's follow-up.
CONCLUSION
Hybrid transvaginal NOTES of radical sigmoidectomy may be safe and feasible for selected patients with sigmoid colon cancer and give less pain, potentially low rates of complication, faster recovery, and better cosmesis. A future large study is warranted to better evaluate this procedure. Although there are many reasons for skepticism, there is undoubted interest in this field from both surgeon and patient.

Solitary fibrous tumors are rare tumors of mesenchymal origin. Although most often observed in the lung pleura, they have been reported in varied extrapleural sites. A 70-year-old male with complicated Crohn's disease presented with 3 days of nausea, emesis, constipation, and abdominal pain. Computed Tomography (CT) demonstrated mucosal thickening of the middescending colon, consistent with fibrosing stricture. Surgical excision revealed an unusual, 5 cm mass originating in the subserosa. Histopathology of the lesion was notable for a proliferation of cells with spindle and stellate-shaped nuclei and no appreciable mitotic figures, which extended into the muscularis and submucosa. Immunohistochemistry was STAT6 nuclear positive and cytoplasmic CD34 positive, diagnostic for solitary fibrous tumor (SFT). In this case, the SFT infiltrating into the muscularis propria and subserosa caused the stricture and bowel obstruction. This illustrates that while fibrosing strictures are usually the etiology of bowel obstruction in the setting of Crohn's disease, other rare possible causes should be considered.

BACKGROUND
In animal studies, the inhibition of VEGF activity results in high mortality and impaired renal and glomerular development. Mechanical stimuli, like mechanical stretch in respiratory and circulatory systems, results in an elevated expression of VEGF. In animal models, the experimental urinary obstruction is associated with stretching of tubular cells and activations of the renin-angiotensin system. This results in the upregulation of vascular endothelial growth factor (VEGF) and TNF-alfa.
MATERIAL/METHODS
Tissue samples from urinary tract obstruction were collected and immunohistochemistry was performed in 14 patients (average age: 7.1±4.1 years). The control histology group consisted of ureteropelvic junction tissue from 10 fetuses after midtrimester artificial abortion. The fetuses did not have any failure at ultrasound screening and pathological examination. The mean gestational age was 20.6 weeks of gestation (±2.2SD). Expression of VEGF was detected with immunohistochemistry method.
RESULTS
Expression of VEGF was found in varying intensity in the submucosa and subserosa layers, but only in the test tissue (placental tissue). The tissue of the patients with urinary obstruction and the tissue of the fetal ureteropelvic junction without urinary obstruction were negative for expression of VEGF. The repeated examination showed negative cells and no color staining.
CONCLUSIONS
The pressure due to congenital urogenital obstruction resulting in mechanical stress in cells did not increase the expression of VEGF in young children in our study. To find a correlation between urogenital tract obstruction and increased expression of VEGF, we need to perform more examinations because the connection may be of therapeutic significance.

BACKGROUND
Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare ischemic bowel disease with venous occlusion resulting from the proliferation of smooth muscles in the venous intima. In most patients, the disease affects rectosigmoid colon and causes persistent abdominal pain and hematochezia, which is similar to inflammatory bowel disease (IBD). In addition, it is difficult to make a precise diagnosis of IMHMV without surgery.
CASE PRESENTATION
An 81-year-old woman was admitted to our hospital with mild abdominal pain, nausea and vomiting. Repeated adhesive ileus was suspected due to the previous open and laparoscopic surgeries. Surgery was planned to treat small bowel obstruction. Intraoperatively no adhesive lesions were observed. However, a mass lesion was seen at the terminal ileum, which was suspected to have caused her bowel obstruction. Partial resection of the small intestine was performed. Macroscopic and histopathological examinations of the excised specimen showed circumferential ulceration with scarring, a thickened venous wall with active inflammation, and fibrotic changes that consequently produced stenosis and obstruction of the venous lumen in the subserosa. Additionally, Elastica van Gieson staining demonstrated thickening of the venous intima. The final diagnosis was IMHMV. At two years and 8 months after the operation, the patient was well without any additional medication.
CONCLUSION
IMHMV of the small intestine is rare. We described a case of IMHMV that was associated with ileus.

OBJECTIVES
The goal was to examine the efficiency of local implementation of adipose-derived mesenchymal stem cells, which have an anti-inflammatory effect, in preventing the intra-abdominal adhesions in rats.
MATERIAL AND METHODS
Twenty-one Wistar albino rats were randomly divided into 3 groups, 7 rats in each: Group 1 was defined as the control group, Group 2 as the sham group, and Group 3 as the adipose-derived mesenchymal stem cell group. A 6 cm mid-abdomen incision in the all the rats was performed. The cecum serosa and sub-serosa were injured by rubbing with a gauze. No agent was applied intraperitoneally for the rats in Group 1; 1.5 mL saline and 2x10/kg allojenic adipose-derived mesenchymal stem cells in the 1.5 mL saline were injected into peritoneum of rats in Groups 2 and 3, respectively. Laparotomy was performed on the 14 day. Adhesion scores, histopathological examination, E-cadherin expression, and the tissue hydroxyproline level were evaluated.
RESULTS
The general adhesion score and collagen deposition in Group 3 were found to be significantly higher than in Groups 1 and 2 (p=0.003 and p=0.009, respectively). In the inflammatory cell comparison, a significant decrease was found in Group 3 in proportion to Groups 1 and 2 (p=0.001, p=0.005, respectively). The E-cadherin levels were found to be higher in Group 3 (p=0.003).
CONCLUSION
Severe adhesion was observed in the adipose-derived mesenchymal stem cells group. Collagen intensity and E-Cadherin expression also increased in the adipose-derived mesenchymal stem cells group. The anti-inflammatory effect was also seen in the adipose-derived mesenchymal stem cells group.
