ACTH-secreting neuroendocrine pancreatic tumor: a case report.
AbstractIntroductionIncidence of neuroendocrine tumor (NET) is increased in the last thirty years from 1.1 to 5.2 cases per 100,000 people in the United States. They can originate from the pancreatic gland and for the majority of cases are not functioning (80%). A small percentage of functioning may produce adrenocorticotropic hormone (ACTH) and lead to ectopic ACTH Syndrome (EAS), responsible of Cushing-Syndrome.ResultsWe present a case of a 30 year-old woman suffering from EAS due to a neoformation of the pancreatic tail of the maximum diameter of 4 cm. The lesion was resectable at preoperatory imaging. The patient was subjected to distal splenopancreasectomy. Histological examination showed a well-differentiated neuroendocrine carcinoma pT3N0. The postoperative course was regular. At two years of follow-up patient is almost completely asymptomatic for Cushing's but she has developed multiple liver metastases, for which she began chemotherapy.Discussionp-NET responsible for EAS is usually malignant and the radical treatment of excision of the lesion is not possible because they occur at the time of diagnosis with liver metastases or unresectable. Our patient had a mass at the time of diagnosis resectable but despite radical surgery, she has developed multiple liver metastases at two years and she was undergoing chemotherapy.ConclusionsIn agreement with previous literature we confirm the aggressive nature of pancreatic tumors secreting ACTH, despite radical surgery. Conversely, surgical treatment is effective on the resolution of clinical symptoms

Difficult abdominal access in laparoscopic cholecystectomy in elderly patients: our experience and literature review.
AbstractLaparoscopic cholecystectomy (LC) is currently the gold standard treatment for symptomatic cholelithiasis. LC is actually condidered a medium complexity surgical operation. LC could be technically hard, especially if patient underwent previous surgical operation. These difficulties increase in outcome of previous operation in right upper quadrant (RUQ): in this case laparoscopic access is defined as an “hard access”. We present two cases in which an unconventional access was performed: laparoscopic cholecistectomy is a safe and feasible procedure, although a careful assessment preoperative is indispensable. In particular, caution is required in both the triangulation of the trocar, which in pneumoperitoneum induction

Anal sphincter dysfunction in multiple sclerosis: An observation manometric study
Constipation, obstructed defecation, and fecal incontinence are frequent complaints in multiple sclerosis. The literature on the pathophysiological mechanisms underlying these disorders is scant. Using anorectal manometry, we compared the anorectal function in patients with and without multiple sclerosis. 136 patients referred from our Center for Multiple Sclerosis to the Coloproctology Outpatient Clinic, between January 2005 and December 2011, were enrolled. The patients were divided into four groups: multiple sclerosis patients with constipation (group A); multiple sclerosis patients with fecal incontinence (group B); non-multiple sclerosis patients with constipation (group C); non-multiple sclerosis patients with fecal incontinence (group D). Anorectal manometry was performed to measure: resting anal pressure; maximum squeeze pressure; rectoanal inhibitory reflex; filling pressure and urge pressure. The difference between resting anal pressure before and after maximum squeeze maneuvers was defined as the change in resting anal pressure calculated for each patient. RESULTS: Group A patients were noted to have greater sphincter hypotonia at rest and during contraction compared with those in group C (p=0.02); the rectal sensitivity threshold was lower in group B than in group D patients (p=0.02). No voluntary postcontraction sphincter relaxation was observed in either group A or group B patients (p=0.891 and p=0.939, respectively). CONCLUSIONS: The decrease in the difference in resting anal pressure before and after maximum squeeze maneuvers suggests post-contraction sphincter spasticity, indicating impaired pelvic floor coordination in multiple sclerosis patients. A knowledge of manometric alterations in such patients may be clinically relevant in the selection of patients for appropriate treatments and for planning targeted rehabilitation therapy
