ABSTRACT

Background and study aims Surgery is the considered the therapeutic cornerstone for pancreatic neuroendocrine tumors (P-NETs), although burdened by high risk of significant adverse events. Recently, endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has been described for P-NETs. We aimed to evaluate the effectiveness and safety of EUS-RFA for treatment of P-NETs. Patients and methods We prospectively included all consecutive patients with P-NET ≤ 20 mm who were treated with EUS-RFA and were followed-up for at least 12 months. Results Ten patients (5 males, mean age 78.6 years, mean body mass index 28.2) with 11 P-NETs (mean size 14.5 mm; range 9 - 20 mm) localized in the pancreatic head (3 lesions), pancreatic body (5 lesions), and tail (3 lesions) underwent complete EUS ablation with one session of RFA. Complete ablation of P-NET was reached using a single-session RFA with a mean of 2.3 treatment applications per session. At both 6 - and 12-months computed tomography scans, all the patients had complete disappearance of lesions with radiological normalization. Regarding safety, only two cases of mild abdominal pain were recorded in two subjects with pancreatic head lesion, which were effectively treated with analgesics. The mean duration of hospital stay was 4 days (range 3 - 7 days). Conclusions EUS-RFA is effective and safe in treating P-NETs. It may be considered an effective therapeutic option in the treatment of small P-NETs independently from their functional status.

ABSTRACT

Periampullary neoplasms are a heterogeneous group of tumors arising within 2 cm of the ampulla of Vater. Neuroendocrine tumors can originate throughout the entire body, from neuroendocrine cells. These neoplasms exhibit deep differences, according to their origin and biological behavior. We describe a case of a 79-year-old man who underwent pancreaticoduodenectomy for adenocarcinoma of the ampulla of Vater after proper staging. At gross histology, an incidental pancreatic neuroendocrine tumor was also documented. Despite two synchronous neoplasms, the patient survived 34 months with no evidence of recurrence at follow-up. The synchronous presence of a second primitive tumor in patients affected by a neuroendocrine tumor is reported in the literature; incidence is variable and the most common site is the gastrointestinal tract. Diagnostic workup for ampullary neoplasms includes abdominal computed tomography (CT) scan, magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS). These investigations infrequently may detect subcentimetric lesions. We believe this case is currently extremely rare. Preoperative diagnosis of synchronous PanNET would not have changed our approach since surgical therapy represents the gold standard in resectable ampullary neoplasms, and it has a primary role in the prognosis of the present patient.

ABSTRACT

INTRODUCTION: Endometriosis is the growth of endometrium outside the uterine cavity. In 5-15% of cases the disease can affect the colon and small bowel, causing complete obstruction and requiring resection in about 1% of cases. CASE SUMMARY: We describe a case of sigmoid obstruction due to endometriosis in a 38 years old woman with personal history of endometriosis. She was admitted for abdominal pain and constipation. The patient was treated with endoscopic stenting and subsequent laparoscopic sigmoidectomy. DISCUSSION: Bowel obstruction caused by endometriosis is a rare event. Its diagnosis can thus be a clinical and radiological challenge but it may be suspected in all young woman with colonic obstruction. At present, the management of endometriosis is an integrate approach of both medical and surgical therapy. In case of irreversible colonic obstruction surgery is mandatory. The treatment of choice is usually an emergency procedure (either Hartmann procedure or resection and anastomosis with stoma placement). This approach entails all the risks related to emergency procedures and can have important psychological and biological drawbacks. CONCLUSION: Endoscopic prosthesis placement as bridge to surgery is a feasible therapeutic strategy in colonic obstruction due to endometriosis. It brings about all the advantages of an expedited one step laparoscopic surgical procedure. Laparoscopic elective resection has a lower rate of stoma placement and has a postoperative pregnancy rate grater than open surgery.

ABSTRACT

Traumatic hernia of the abdominal wall is a rare type of hernia. A high-energy, localised impact causes the disruption of the abdominal wall musculature without penetrating the skin. The most frequent cause of the trauma is the lower abdomen striking the end of bicycle handlebars in young adults and children. A high level of clinical suspicion is required for diagnosis because of the high rate of associated injuries. The authors report a case of handlebar hernia managed successfully by surgical repair.
