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.

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
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.

Pneumatosis cystoides intestinalis (PCI) is a rare disease characterized by the presence of multiple gas-filled cysts within the submucosa or subserosa of the intestinal wall. We report a case of PCI in a 54-yearold man 4 weeks after liver transplantation due to hepatitis B virus (HBV)-associated liver cirrhosis presenting with illness, diarrhea and abdominal pain. CT scans revealed normal shape of the abdominal parenchymal organs and no intra-hepatic complication due to liver transplantation. Main abdominal venous and arterial vessels resulted patent. Colic loops appeared diffusely thickened for the presence of variable diameter air-filled cysts located within the bowel wall. The patient underwent conservative treatment and the CT control after 4 weeks showed a complete PCI resolution. PCI after adult liver transplantation is probably due to the pre-transplantation chemotherapy, immunosuppressive therapy and opportunistic enteric infections. Abdominal CT represents the gold standard technique for diagnosing PCI and for evaluating its extension and complications providing data on other abdominal pathologies. It appears as variable diameter gas-filled cysts located within the bowel wall and it is often associated with pneumo-peritoneum probably due to the rupture of subserosal cysts. PCI has a favorable outcome and requires conservative treatment. Major differential diagnosis includes intestinal pneumatosis due to bowel ischemia. PCI after liver transplantation represents an uncommon bowel disease with a favorable prognosis. CT represents the reference imaging technique for diagnosing the disease and evaluating the response to therapy which is usually conservative rather than surgical.

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.

World Journal of Gastrointestinal... Oct 2012To investigate the status of the lymphatic vessels in the small bowel affected by Crohn's disease (CD) at the moment of surgery.
AIM
To investigate the status of the lymphatic vessels in the small bowel affected by Crohn's disease (CD) at the moment of surgery.
METHODS
During the period January 2011-June 2011, 25 consecutive patients affected by CD were operated on in our Institution. During surgery, Patent Blue V was injected subserosally and the way it spread along the subserosa of the intestinal wall, through the mesenterial layers towards the main lymphatic collectors and eventually to the lymph nodes was observed and recorded. Since some patients had been undergone strictureplasty at previous surgery, we also examined the status of intestinal lymph vessels after previous strictureplasties. The same procedure was performed in a control group of 5 patients affected by colorectal cancer. Length of lesions, caliber, maximal thickness of the diseased intestinal wall, thickness of the wall at injection site and thickness of the mesentery were evaluated at surgery.
RESULTS
We observed three features after the injection of Patent Blue V in the intestinal loops: (1) Macroscopically healthy terminal ileum of patients with CD or colon cancer showed thin lymphatic vessels linearly directed toward the mesentery; (2) In mild lesions in which the intestinal wall did not reach 8 mm of thickness, we observed short, wide and tortuous lymphatic vessels directed longitudinally along the intestinal axis toward disease-free areas and then transversally toward the mesentery; and (3) Injection in the severely affected lesions, that had a thickness of the intestinal wall over 10 mm, did not show any feature of lymphatic vessels at least on the subserosal surface. There was a correlation between the thickness of the parietal wall and the severity of the lymphatic alterations. Normal lymphatic vessels were observed at previous strictureplasties in the presence of complete regression of the inflammation.
CONCLUSION
Injection of Patent Blue V in the intestinal wall could help distinguish healthy tracts of the small bowel from those macroscopically borderline.

The origin of endometriosis has multiple theories, with controversy over which may demonstrate the prominent pathophysiology. The most common extra-pelvic organ system affected by endometriosis is the gastrointestinal tract. Gastrointestinal endometriosis (GE) accounts for 3 to 37% of all endometriosis cases, and appendiceal endometriosis is present in around 3% of GE cases, therefore constituting less than 1% of all endometriosis cases. In this report, we present a 24-year-old female with a past medical history significant for endometriosis status post two excisional laparoscopies who presented with eight months' duration of right lower quadrant pain, constant and stabbing, with rebound tenderness. Appendectomy and histopathology demonstrated focal endometriosis, diffuse serosal fibrovascular adhesions involving the appendiceal serosa/subserosa, as well as a dilated lumen filled with hemorrhagic content. When the appendix is not considered in endometriosis pathology, patients are at increased risk for unresolved pain and further laparoscopic procedures. Prophylactic appendectomy appears to be a worthwhile consideration in patients with chronic pelvic pain, given the high frequency of appendiceal pathology.

The presence of a supernumerary subserosal muscle layer of the bowel is an extremely unusual congenital development. The following is a report of diffuse involvement of the intestine with a supernumerary subserosal muscle coat. The current patient, a 29-year-old male, was evaluated in January 2022 for a long-standing history of subacute intestinal obstruction (SAIO). A preoperative CT scan of the abdomen and pelvis suggested mild dilatation and clumping of ileal loops in the right iliac fossa, with a subtle wall thickening of up to 5 mm. Intraoperatively, dense adhesions were noted between clumped bowel loops and the anterior abdominal wall. Following adhesiolysis, ileocecal resection with ileocolic anastomosis was done. The histopathological examination of the resected bowel segment showed irregular hypertrophy of circular and longitudinal muscle layers with the presence of an additional smooth muscle coat outer to the outer longitudinal layer that was seen in the ileum as well as the appendix. No evidence of vacuolar degeneration was noted, and ganglion cells were seen to be adequately present. The presence of additional smooth muscle bundles in the subserosa was confirmed with positive actin immunostaining. Additionally, CD117 staining was done that revealed a normal network of interstitial cells of Cajal. No evidence of active inflammation was noted in the resected bowel segment. Findings from the current case bring to light an extremely rare malformation of the muscularis propria of the intestine, namely a supernumerary subserosal muscle coat.
