Small bowel obstruction due to a congenital adhesion: a rare case report.

The exact incidence of small bowel obstruction (SBO) due to congenital adhesions remains unclear. Herein, we report a 59-year-old male who appeared in the emergency department with diffuse abdominal pain associated with vomiting. The patient reported no previous medical or surgical history. Clinical examination revealed a soft, distended abdomen and diffuse tenderness. Computed tomography indicated a close loop obstruction. A congenital band extending from mesentery to ileum and causing an internal hernia was identified via a midline incision. The band was ligated and divided. There is no difference in the clinical presentation, and the initial work-up of SBO on account of congenital adhesions was compared to other bowel obstruction causes. Surgical exploration is crucial for the diagnosis and treatment of congenital adhesions. Although laparotomy is considered the cornerstone of surgical management, laparoscopy has emerged as a feasible and safe alternative for the diagnosis and treatment of these congenital bands.

Osteoid Osteoma: An Updated Review of Epidemiology, Pathogenesis, Clinical Presentation, Radiological Features, and Treatment Option.

Osteoid osteoma, the third most common benign bone tumor, usually occurs in the cortex of long bones. It consists of a radiolucent nidus surrounded by reactive osteosclerosis. Generally, osteoid osteoma affects young males. Nocturnal pain that eases with salicylates or nonsteroidal anti-inflammatory drugs (NSAID) is the typical clinical presentation. Sometimes, it remains undiagnosed for a long time. Plain radiography and computed tomography are usually sufficient for the diagnosis of osteoid osteoma. Initial treatment includes salicylates and NSAID because the tumor often regresses spontaneously over 2-6 years. Surgical treatment is indicated in case of unresponsive pain to medical therapy, no tolerance of prolonged NSAID therapy due to side effects, and no willingness to activity limitations. Nowadays, minimally invasive techniques have replaced open surgery and are considered the gold standard of surgical treatment. Although cryoablation seems superior in terms of the nerve damage and immunotherapy effect, radiofrequency ablation is the preferred technique.

Primary Epiploic Appendagitis Mimicking Acute Appendicitis: A Case Report and Narrative Review of the Literature.

Primary epiploic appendagitis is uncommon and is estimated to induce 1.1-1.3% of all abdominal pain. We report a 42-year-old male who appeared in the morning in the emergency department with abdominal pain localized in the right lower abdomen and associated with anorexia and nausea. Clinical examination, laboratory tests, and abdominal ultrasound revealed deep tenderness at Mc Burney point and a mild elevation of CRP (0.7 mg/dL). In the evening, the symptoms were exacerbated, and a diagnostic laparoscopy was performed. Intra-operatively, the appendix was normal and a twisted, necrotic epiploic appendage originating from the antimesenteric border of the mid ascending colon was found. Laparoscopic resection of the necrotic epiploic appendage and prophylactic appendectomy was carried out. Histology indicated the diagnosis of the necrotic epiploic appendage. Postoperatively, the patient recovered without complications. Although the preoperative diagnosis of primary epiploic appendagitis has improved due to abdominal ultrasound and mainly CT, there are still cases which are diagnosed during laparoscopy. The treatment of choice is conservative management, while the use of antibiotics remains controversial. The relapse and complication rates are rare. Surgical excision, particularly laparoscopic, should be considered in cases of uncertain diagnosis, persistent symptoms, or recurrence.

Phlebosclerosis in lower extremities veins - a systematic review.

Phlebosclerosis is a venous wall degenerative disease which has gained little popularity in the literature due to its uncertain clinical significance. The objective of this review is to evaluate the epidemiology, etiology and clinical significance of phlebosclerosis in lower extremities veins, particularly the effect of preexisting phlebosclerosis of the great saphenous vein on vein graft patency. Medline was searched from inception until November 1, 2019. Reference lists of included studies were scanned. Only articles published after 1949 were included. Two reviewers independently screened titles/abstracts and full-text papers for any study design in relation to phlebosclerosis in lower extremities veins and abstracted data. A total of 16 Cohort studies and one case-control study (3708 participants, mean age 61.8 years, 59.3 % men, and 40.7 % women) were included after screening 317 titles and abstracts, and 80 full-text articles. The incidence of phlebosclerosis ranged from 1.5-9.7 % depending on the radiological features. On the contrary, the incidence of the phlebosclerotic great saphenous vein prior to its use as a vein graft was 26.9-91 % on histological examination. The small saphenous vein was the most common location of phlebosclerosis followed by the great saphenous vein. There is a link between phlebosclerosis and age, venous insufficiency and haemodialysis. As for the vein graft patency seven studies demonstrated a correlation between preexisting phlebosclerosis and vein graft stenosis, whereas three studies failed to prove any association. In conclusion, the radiological incidence of phlebosclerosis depended on the ultrasound findings. Its presence in the great saphenous vein prior to its use as a vein graft is established on histological examination. The small saphenous vein is mainly affected. Risk factors included age, haemodialysis, and venous insufficiency. Preexisting wall thickness of the great saphenous vein graft seemed to affect negatively its patency in bypass surgery.

Short-term evaluation of liver tumors after transarterial chemoembolization: limitations and feasibility of contrast-enhanced ultrasonography.

PURPOSE: To evaluate the limitations and the feasibility of contrast-enhanced ultrasonography (CEUS) for the assessment of tumor response shortly after transarterial chemoembolization (TACE). MATERIALS AND METHODS: Fifty seven patients (41 patients with hepatomas, 16 patients with metastases) were studied with CEUS before, 1 day after, and 30 days after TACE. A CEUS-efficiency score (CEUS-ES) was calculated, which evaluated: (a) the completeness of visualization of the target tumor(s) (2: good, 1: adequate, 0: poor) and (b) the quality of delineation of post-TACE necroses (2: good, 1: adequate, 0: poor). A CEUS study was considered as "diagnostic," if each of the aforementioned parameters was associated with grade 1 or 2. RESULTS: CEUS studies were "diagnostic" in 36/57 patients (63.1%). Patients with hepatomas were more likely to undergo "diagnostic" CEUS than patients with metastases (70.7% vs. 43.7%, P = 0.0728). Lesions' multiplicity, deep location, hypoenhancement on pretreatment CEUS, and diffuse growth had a statistically significant (P < 0.05) negative impact on CEUS-ES. Hyperechogenicity on pre-treatment, unenhanced US had a non-statistically significant (P = 0.176) negative impact. Differences between "diagnostic" CEUS studies and CT/MR regarding detection of residual tumor were insignificant (P = 0.8178). CONCLUSION: The percentage of lesions which are unsuitable for post-TACE evaluation with CEUS is not negligible. For the rest, the respective role of CEUS is promising.

Sarcomatoid carcinoma of the prostate: a case report.

Sarcomatoid carcinoma of the prostate is a rare variant of prostatic cancer, with less than 100 cases reported in the literature up to date. Tumors are most commonly composed of an admixture of both malignant glandular and spindle cell elements. The sarcomatoid component can vary from 5 to 99%. We report a case of a 76-year old Caucasian man who underwent transurethral resection of the prostate for the treatment of bladder outlet obstruction. Histopathologic examination revealed a tumor with malignant epithelial and sarcomatous elements. The malignant epithelial component consisted of poorly differentiated adenocarcinoma (Gleason score 5+4=9/10) and the sarcomatous component was mainly composed of undifferentiated spindle cells. On immunohistochemistrythe latter expressed a positive staining for vimentin. Several cells were positively stained for cytockeratin AE3 and myoD1 while all were negative for actin, desmin and myogenin. The diagnosis of sarcomatoid carcinoma was finally made. Although sarcomatoid carcinoma of the prostate is a highly aggressive neoplasm and patients have a poor prognosis, our patient is still alive one year after diagnosis.
