The Authors discuss on a laparoscopic-assisted approach for excision of a sessile villous adenomatous polyp of the cecum, unresectable by endoscopy. Because of the large implant of the polyp, endoscopic polypectomy was considered at high risk and a surgical laparoscopic procedure was scheduled for removal of the lesion. After right colon mobilization, an intraoperative endoscopy confirmed the location of th polyp in the posterior wall of the cecum, closed to the ileo-cecal valve. A small 10 cm laparotomy, through which the cecum was pulled out the abdominal cavity, was performed. Then, a minimal colotomy along the intestinal taenia was carried out to allow a safe and complete excision of the polyp. This laparoscopic approach differs from the other laparoscopic-assisted methods reported in the Literature since it provides at the same time the postoperative advantages associated with minimal access surgery and a safe oncological removal of the polyp with low risks of complications.

Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

Venous thromboembolism (VTE) is a frequent complication in patients undergoing major surgery, with the possibility of long-term disability or fatal outcome. The rationale of the thromboprophylaxis in all patients can be summarized in three points: 1) the VTE is common in some types of surgery; 2) the VTE can be fatal; 3) thromboprophylaxis is highly effective and safe and, besides these clinical benefits, leads to lower total costs of treatment without further diagnostic and a new shelter for treating venous thrombosis. The surgical patients may present at admission one or more risk factors for VTE, The effect of this risk is cumulative, it is important to stratify the risk and to established an adequate prophylactic strategy. Today there is a unanimous consensus that the low molecular weight heparins are both effective and safe in preventing VTE in surgical patients. Unanimously approved guidelines can help surgeons in making decisions regarding VTE prophylaxis.

Laparoscopic colo-rectal surgery has been increasingly accepted and performed in several surgical centres. However, there are still concerns about the intra-operative risks and therefore on the safety of the procedure especially during the learning curve. As a matter of fact, in approximately one third of laparoscopic colo-rectal procedures, an intra-operative complication, mainly bleeding or iatrogenic injuries, may occur. In this paper, according to our experience, we analyse step by step the surgical technique of the laparoscopic left colectomy and evaluate the technical difficulties and complications in order to avoid them.

Adrenal myelolipoma is a rare benign, non-functioning tumor consisting of fat and hematopoietic tissues. In January 2005 we had observed an adrenal myelolipoma in 70 year old man. During the follow-up for bladder urothelioma, an abdominal CT revaled a well delineated 4x4 cm homogeneous fatty mass in the right suprarenal area with negative attenuation values. The functional study of adrenal gland was normal. The patient underwent videolaparoscopic right adrenalectomy (Gagner technique). Postoperative course was uneventful. The istological diagnosis showed adrenal myelolipoma. We conclude that videolaparoscopic adrenalectomy should be considered the gold standard treatment for benign adrenal lesions.

Treatment of liver hydatid cyst is still controversial. Besides medical treatment, interventional radiologic techniques and traditional surgery, recently the laparoscopic approach has been proposed. Laparoscopic treatment of liver hydatid cyst, however, has not been well defined so far and seems to be associated with a recurrence rate from 0 to 9%, in a 3-49 months follow-up. Disadvantages of the laparoscopic approach are difficult control of spillage, peritoneal dissemination of parasites and incomplete aspiration of high density fluid contents of the cyst. The authors have reviewed the literature and describe a personal technique to avoid this disadvantage and to reduce postoperative recurrence rate.

The occurrence of post-operative pain, although less severe and frequent than in open surgery, may affect length of hospital stay and early return to normal activity in some patients operated on with laparoscopic surgery. Although several pathogenetic factors have been indicated in the literature, the mechanism responsible for post-operative pain after laparoscopy; still remains unclear. In this study the Authors evaluated post-operative pain in 90 patients submitted to laparoscopic cholecystectomy and correlated it to the length of operation, endoabdominal CO2 pressure maintained during surgery, and use of local anesthesia instilled din the liver bed and in the sites of introduction of trocars. Measuring post-operative pain by means of a modified Scott-Huskisson Visual Analogue Scale, no difference in the severity of the pain was noted in the two subgroups of patients with a length of operation inferior or superior to 60 minutes, respectively. Conversely, a statistical significant difference (p = 0.04 and p = 0.049 according to Fisher exact test and Pearson test, respectively) was observed evaluating the use of local anesthesia and the level of CO2 endoabdominal pressure, with less pain in patients whose pressure was maintained under 10 mmHg and in patients treated with instillation of local anesthetic drugs in the liver bed and in the sites of introduction of trocars.

The authors report a rare case of stenotic sigmoid endometriosis which presented with constipation and dysmenorrhea in a 48-year-old woman without past gynecological history. There were no typical radiological and endoscopic findings and only pathological examination revealed endometriosis. The patient did well after sigmoid resection and bilateral salpingo-oophorectomy and has had no further complaints. The authors stress the rare location of the disease and review the literature about etiopathogenetic hypotheses and pathological features. The diagnostic value of clinical examination, barium enema and colonoscopy is low as endometriosis rarely involves the mucosa. This case led the authors to discuss about diagnostic difficulties, differential diagnosis and therapeutic options.

The authors report a rare case of mesenteric cyst in a 36 years old woman. These cysts have a pathogenesis that primarily may be ectopic lymphatic tissue and their most common site is in the small bowel mesentery, especially of the ileum. In the case reported the cyst was located in the right mesocolon. Mesenteric cysts can appear as chronic abdominal pain, a painless abdominal mass, or acute abdomen. Diagnostic aids include abdominal computed tomography and sonography, that usually make diagnosis of mesenteric cyst. Treatment of choice is enucleation; resection of the adjacent bowel may occasionally be necessary.
