Hepatocellular carcinoma (HCC) is an increasingly common form of cancer. Although its spontaneous rupture is rare in Western countries, it constitutes a surgical emergency and is associated with high mortality. There is a lack of consensus as to the best approach and what parameters to use in choosing it. The three main approaches are conservative, endovascular and resection - the treatment of choice for acute abdominal bleeding. We report a case of hemoperitoneum following the spontaneous rupture of an unrecognized HCV-related HCC in a patient with no history of liver disease. The patient was successfully treated by emergency surgery, with resection of two segments of the left liver.

Introduction. Small bowel adenocarcinoma is a rare tumor, with a still not well studied tumorigenesis process, and non-specific symptoms that cause a delay in the diagnosis and consequently a worst outcome for the patient. Videocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) have revolutionized the diagnosis and management of patients with small bowel diseases. Surgery is the treatment of choice when feasible, while the chemotherapeutic approach is still not well standardized. Case reports. Two cases in 2 months (two women 52 and 72-yr-old) of primary bowel adenocarcinoma is reported. The site of the tumor was in jejunum, instead of the most common site in duodenum. The patients underwent DBE with biopsy and ink mark. Laparoscopic-assisted bowel segmental resection was performed. The pathologic diagnosis was primary jejunum adenocarcinoma. No post-operative mortality or significant morbidities were noted. Conclusion. The combination of DBE and laparocopic-assisted bowel surgery represents an ideal diagnostic and therapeutic method.

Introduction. Synchronous occurrence of pulmonary and hepatic hydatid cysts is an uncommon manifestation of hydatid disease that is observed in less than 10% of cases. We report a rare case of bilateral lung (with bronchial fistula) and liver cyst, surgically treated after medical therapy. Case report. A 44-year-old housewife reporting fever, anorexia and fatigue that had been present for the previous 20 days received diagnosis of bilateral lung and liver hydatid cyst. Because of the dimensions of right lung cyst and the successive bronchial fistolization, we proceeded to three-stage operation of two thoracotomies and a laparotomy to control the risk of further rupture. After surgery, all post-operatives were uneventful. Complete resolution of the therapy with no evidence of recurrence at 2 years follow-up. Conclusion. We emphasize the need to search for additional hydatids in patients who present with either pulmonary or liver hydatids. The simultaneous treatment of liver and lung should be reserved to patients in good conditions; in all other cases, especially when one cyst is more symptomatic than the others or has more risk of rupture, we prefer to treat single cyst.

The incidence of anastomotic stricture following colorectal surgery has increased in recent years. This complication is observed in 2-5% of all operated patients and is probably due to the greater number of low anastomoses performed with surgical staplers. We observed 31 patients with postoperative stricture, arising from one to nine months post-surgery. All patients had been treated for colorectal cancer and underwent endoscopy either during routine follow-up or for symptoms of stenosis. In 16 patients (group A) the stricture diameter was less than 4 mm and the patients had symptoms attributable to partial bowel obstruction. In the remaining 15 patients (group B), who had difficult bowel movements, the stricture diameter ranged from 4 to 8 mm. All patients were treated with endoscopic dilation using achalasia balloons. The results were considered good when the post-dilation anastomosis diameter achieved was at least 13 mm, fair when it was 9-12 mm and poor when it was less than 9 mm. The short term results (3 weeks) were good in 27 patients (87.2%), fair in 3 patients (9.6%), and poor in 1 patient (3.2%). After several unsuccessful dilations, the latter was treated by surgery. Follow-up at 3-4 months of the remaining 30 patients revealed good results in 20 (66.6%), fair in 6 (20%), and poor in 4 (13.3%). In 1 of these 4 patients, cancer recurrence was observed and a new surgical resection was performed. In 2 patients a self–expandable metal stent was inserted for 4-6 weeks, with satisfactory results. In 1 patient a biodegradable polydioxanone stent was inserted with good results after 6 months. Follow-up at 3-4 months showed good results in 25 patients. After 38 months, cancer recurrence in the area of the anastomosis was observed in 1 patient, who was treated surgically. Endoscopic dilatation should be considered the first therapeutic approach in case of anastomotic strictures, as it is immediately effective, repeatable, and does not preclude surgery if this should become necessary. .

Esophageal perforation is associated with significant mortality and morbidity. Its etiology is as heterogenous as modalities currently employed for its treatment. There is no clear evidence which is the treatment of choice for esophageal perforation. This is partly due to the suboptimal quality of available studies and failure to accurately report on the characteristics, treatment and outcome of these patients. Indeed, baseline, operative and outcome data are important for a better evaluation of published data and possibly for including them in meta-analyses of aggregate or individual patient data. We propose a checklist for reporting data on esophageal perforation in order to standardize reporting of data of studies on this severe condition.

Introduction. Laparoscopic approach for treatment of colorectal lesion is gaining acceptance gradually. Evidence from numerous randomised controlled trials has shown the short-term benefits of laparoscopic colon resection over open surgery, and its long-term outcomes also does not differ considerably from those of open surgery. This study aims at a retrospective analysis of operative and short term outcomes of patients. Patients and methods. All laparoscopic colon and rectal resections performed between September 2004 and September 2011 were included. The clinical parameters, operative parameters and short-term outcome details of laparoscopic colorectal surgery patients were collected from the retrospectively reviewed database. Results. A total of 347 patients, median age 71 years (range 32 to 96), underwent laparoscopic resection of the colon and rectum. The median Body Mass Index (BMI) was 26.5. The majority of the procedures were performed for malignant disease (97,1%) and the most common procedure was right colectomy (41%). The median duration of surgery was 202,3 minutes, with conversion to open surgery in 40 patients (11.5%). Complications occurred in 23 patients (6.6%). The median length of hospital stay was 8.9 days. In patients with malignant disease, the median number of lymph nodes removed was 14.9. Conclusion. Our results show that laparoscopic approach for colon-rectal lesions is safe, feasible and produces favourable results. The most important aspect of surgery for malignant disease is the ability to remove radically the disease. However all data are still related to the experience of the operator.

Aim. Laparoscopic Appendectomy (LA) is widely performed for the treatment of acute appendicitis. However the use of laparoscopic approach for complicated appendicitis is controversial, in particular because it has been reported an increased risk of postoperative IntraAbdominal Abscess (IAA). The aim of this study was to compare the outcomes of LA versus Open Appendectomy (OA) in the treatment of complicated appendicitis, especially with regard to the incidence of postoperative IAA. Patients and Methods. A retrospective study of all patients treated at our institution for complicated appendicitis, from May 2004 to June 2009, was performed. Data collection included demographic characteristics, postoperative complications, conversion rate, and length of hospital stay. Results. Thirty-eight patients with complicated appendicitis were analysed. Among these, 18 (47,3%) had LA and 20 (52,7%) had OA. There were no statistical differences in characteristics between the two groups. The incidence of postoperative IAA was higher (16,6%), although not statistically significant, in the LA compared with OA group (5%). On the other hand the rate of wound infection was lower (5%) in the LA versus OA (20%). Conclusion. Our study indicated that LA should be utilised with caution in case of perforated appendicitis, because it is associated with an increased risk of postoperative IAA compared with OA.

This is a case of a 43-year-old primigravida primipara woman who presented in our Department in 36 weeks gestational age and underwent caesarean section due to preeclampsia. From her history, it was known that her pregnancy was an in vitro fertilization (IVF) result. She also received low molecular weight heparin because of thrombophilia (protein S insufficiency). We present this case of postpartum thrombocytosis and discuss the differential diagnosis of this condition through the presentation of its management.

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. .

Despite the high incidence of abdominal traumas, traumatic abdominal wall hernias (TAWHs) remain rare probably because of elasticity of the abdominal wall. The TAWH is due to blunt abdominal trauma with disruption of the abdominal wall muscles and fascia with intact overlying skin. TAWH can be classified into high energy injures (generally motor vehicle accidents) and low energy injures (impact on a small blunt object). Common example of the latter type is a fall onto a bicycle handlebar. The mechanism of the trauma includes sudden increase of intra-abdominal pressure and extensive shear forces applied to the abdominal wall. The diagnosis of TAWH is difficult in the Emergency Room because during the primary diagnostic process most attention is directed toward the detection of internal injures and TAWH can be missed. In this article we report a case of TAWH caused by a work accident (an heavy steel tube fallen onto the abdominal wall of the patient from a height of five meters) with delayed diagnosis.

Single Incision Laparoscopic Surgery (SILS) is a recent surgical technique, first described in the 1990s. Its aim is to optimize the esthetic result offered by laparoscopy by minimizing the number of abdominal incisions. Various preliminary studies have been carried out on the application of SILS, especially in cholecystectomy and appendectomy. This study evaluates the preliminary results of cholecystectomy by SILS (SILS™ Port) conducted between October 2009 and February 2011 on 21 patients (4 men and 17 women) with a mean age of 49.9 years and a mean Body Mass Index (BMI) of 22.8. All patients were treated by the same team, which had previously undergone six months’ simulator training. There were two main selection criteria, both evaluated intraoperatively: absence of adhesions and of significant inflammatory sequelae from previous cholecystitis; and suitable distance between gallbladder and SILS access port. Conversion to traditional laparoscopy was necessary in just two cases, while an accessory trocar was introduced in another two cases. Conversion to open surgery was not necessary in any case. One case of SILS cholecystectomy was complicated by postoperative bile leakage, which was treated conservatively, as the fistula had a low output. The mean duration of hospitalization was 3.6 days. This preliminary experience led us to conclude that SILS is safe and highly satisfactory in the postoperative phase, thanks to the reduced need for painkillers and the improved esthetic result.

Objective. Minimally invasive video-assisted thyroidectomy (MIVAT) is a technically demanding procedure and requires a surgical team skilled in both endocrine and endoscopic surgery. A time consuming learning and training period is mandatory at the beginning of the experience. The aim of our report is to focus some aspects of the learning curve of the surgeon who practices video-assisted thyroid procedures for the first time, through the analysis of our preliminary series of 36 cases. Patients and methods. From September 2004 to April 2005 we selected 36 patients for minimally invasive video-assisted surgery of the thyroid. The patients were considered eligible if they presented with a nodule not exceeding 35mm in maximum diameter; total thyroid volume within normal range; absence of biochemical and echographic signs of thyroiditis. We analyzed surgical results, conversion rate, operating time, post-operative complications, hospital stay, cosmetic outcome of the series. Results. We performed 36 total thyroidectomy. The procedure was successfully carried out in 33/36 cases. Post-operative complications included 3 transient recurrent nerve palsies and 2 transient hypocalcemias; no definitive hypoparathyroidism was registered. All patients were discharged 2 days after operation. The cosmetic result was considered excellent by most patients. Conclusions. Advances in skills and technology have enabled surgeons to reproduce most open surgical techniques with video-assistance or laparoscopically. Training is essential to acquire any new surgical technique and it should be organized in detail to exploit it completely.

Introduction. Thymomas (THs) are rare epithelial tumors of the thymus gland. In this study we report our personal experience in the management and surgical treatment of THs. Case reports. We report two clinical cases treated with combined therapy (surgery followed by adjuvant therapy). Results. Total transternal thymectomy was performed in both patients. The post-operative course was uneventful. The patients received adjuvant radiotherapy and chemotherapy. No relapse has been observed during follow-up. Discussion. THs are usually slowly growing tumors with similar incidence in both sexes. They occur through a wide age range, with a peak in the fifth and sixth decades. Distinctive features reminiscent of the normal thymus make the pathologic diagnosis of THs easy in most cases. Malignant behaviour is indicated by microscopic or macroscopic invasion of the tumor capsule or surrounding organs or by the presence of metastases. Although there is no standardized staging system for thymoma, the one proposed by Masaoka is commonly employed. Total thymectomy is the procedure of choice, even for encapsulated tumors, with carefully exploration of the mediastinum for evidence of ectopic thymic tissue or local invasion. Conclusions. Despite an indolent course and a cytologically bland appearance, all thymic tumors can manifest a malignant behavior. Surgery continues to be the mainstay of treatment, and the ability to achieve complete resection seems to be the most important prognostic factor. Multimodality treatment involving postoperative chemotherapy and radiotherapy appears to increase the rate of complete resection and improves survival in advanced THs.

Background. In the treatment of differentiated thyroid cancer (DTC), in absence of enlarged lymph nodes, the role of routine central lymph node dissection (RCLD) remains controversial. The aim of this study is to analyze data resulting from total thyroidectomy (TT) not combined with RCLD in the treatment of DTC. Methods. We retrospectively evaluated the clinical records of 80 patients treated between January 1996 and December 2003 with TT without RCLND, in absence of suspected enlarged lymph nodes at preoperative ultrasonography and intraoperatively during neck exploration. In this series, 75 patients (93.7%) underwent radioiodine (RAI) ablation, followed by Thyroid Stimulating Hormone (TSH) suppression therapy. In case of locoregional lymph nodal recurrence, a central (VI) and ipsilateral (III-IV) selective lymph node dissection was performed. Results. Incidence of permanent hypoparathyroidism (iPTH < 10 pg/ml) and unilateral temporary vocal fold paralysis were respectively 2.55% and 2.55%. Locoregional recurrence, with positive cervical lymph nodes, after a 10.3 ± 4.7 years mean follow-up was observed in 3 patients (3.75%). They were submitted to a central (VI) and ipsilateral (III-IV) selective neck dissection without significant complications. Conclusions. In our series, TT not combined with RCLD was associated to a low locoregional recurrence rate, even if the lack of a control group treated with RCLD does not allow any generalized assumption. RCLD may be indicated in high risk patients, in whom lymph nodal recurrence is more frequent. More prospective randomized studies are needed to better define the role of RCLD and postoperative radioiodine ablation.

Pathogenesis, classification and treatment of non-parasitic splenic cysts (NPSCs) are controversial. The utility of percutaneous aspiration of the cyst is not well understood. We report a case of a 32 year-old woman with a symptomatic giant epidermoid cyst of the spleen treated with laparoscopic splenectomy. A percutaneous transcatheter drainage was performed under ultrasound guidance before surgical procedure in order to classify the type of cyst and to choose the best treatment.
