[Laparoscopic appendectomy. Our experience]. / Appendicectomia laparoscopica. Esperienza personale.

The advantages and applications of the videolaparoscopic technique (VL) versus open surgery in the treatment of acute and complicated appendicitis are not well defined. Our study examined 150 patients, 67 males and 83 females. They underwent surgery for acute appendicitis in emergency. The choice between open or laparoscopic tecnique was due to patient's clinical conditions and surgeon's experience. Two of these patients had no infiammatory process. Eleven patients were affected by gynaecological diseases. The last 137 patients underwent surgery for acute appendicitis and the diagnosis was confirmed. Among them, 35 (25%) were affected by a complicated appendicitis with diffuse or clearly defined peritonitis. In 134 patients the surgery was completed laparoscopically. The conversion rate was 2%. Morbility rate was 3%, due to intra abdominal abscesses secondary to acute complicated appendicitis. The mean operative time was 76 min and the mean hospital stay was 4.8 days. The death rate was 0%. In our experience, laparoscopic appendectomy has significant advantages over traditional open surgery in both acute and complicated appendicitis, especially in young women. In this way, we can diagnose pelvic disease that could be characterized by the same symptoms of acute appendicitis, then we suggest laparoscopic appendectomy even just to complete the diagnostic iter. Laparoscopy is useful in terms of convalescence, postoperative pain, hospital stay, aesthetic outcome and an easier exploration of the peritoneal cavity.

[The role of laparoscopy in surgical treatment of pancreatic cancer]. / Il ruolo della laparoscopia nel trattamento chirurgico del carcinoma pancreatico.

AIM: The authors reviewed their experience in surgical treatment of pancreatic cancer between 2003-2008. METHODS: Eighty two pancreatic cancer patients (median age 66.7 +/- 12.5) with obstructive jaundice were enrolled in our study: 36 (44%) had an endoscopic biliary stent; 46 patients (56%) were eligible for surgery: 14 received a curative surgery (pancreatoduodenal resection; 4 had a laparoscopic procedure) and 32 patients with non resectable tumor a palliative surgery: 18 had a gastro-jejunal with a biliary anastomosis (in 4 patients the hepatic-jejunal anastomosis was performed in laparoscopy), 6 had a gastro-jejunal anastomosis (2 laparoscopic procedure and 8 patients had only an explorative laparoscopy. RESULTS: The resectability rates was 17.1%. Median age in patients treated with endoscopic biliary stent was significantly higher than those underwent surgery (72.3 +/- 12.2 vs. 63.5 +/- 9.6; p < 0.05). Hospital length of stay in patients underwent radical surgery was significantly higher than those who received palliative surgery (18 +/- 6 vs. 10 +/- 5; p < 0.05). Morbility rate, including operative mortality of .3%, was 15.2%. CONCLUSIONS: Laparoscopy is largerly used in major oncologic surgery for several reasons: it minimized surgical manipulations and so post-operative complications. There is enough scientific evidence of low incidence of post-operative complications and long-term results compared to those achieved with traditional surgery.

[Incidental carcinoma in thyroid pathology: our experience and review of the literature]. / Il carcinoma incidentale nella patologia tiroidea. La nostra esperienza e revisione della letteratura.

The diagnosis of incidental thyroid carcinoma in patients submitted to thyroidectomy for a benign disease is quite frequent. A retrospective analysis was performed on 240 patients submitted to surgical intervention in order to establish the incidence of the carcinoma. One hundred sixty five patients (68.75%) were affected by benign disease (132 multinodular goiter, 30 uninodular goiter, 2 Plummer and 1 Basedow) and 75 (31.25%) by carcinoma. In 30 of 165 patients (18.2 %), affected by benign disease, occurred a histological diagnosis of thyroid carcinoma, (18 papillary carcinoma, 6 follicular carcinoma, 5 papillary carcinoma follicular variant and 1 oncocytic carcinoma). In this study it's considered incidental thyroid carcinoma the one occurred in patients who never underwent FNA and there were no suspicious features in all exams that may suggest the presence of carcinoma. Fifteen of the 30 incidental carcinoma (50%) were microcarcinomas; in the other 13, dimensions were more than 1 cm, but less than 2 cm in 9 cases. Two patients had a synchronous carcinoma. Actually these patients are still in a follow up program and no recurrency of disease is occasionally observed. This study shows that the only way to put doubts on the real benignity of the disease is the fine needle aspiration; there are no other instruments that could let think about the occurrence of the carcinoma. Moreover in the majority of cases the incidental carcinoma is a microcarcinoma, it doesn't reach significant volume, may be not centered by a FNAB, but in must cases it's not really biologically aggressive.

[Incidental thyroid carcinoma: a multicentric experience]. / Il carcinoma incidentale della tiroide: esperienza multicentrica.

BACKGROUND: In recent years it has seen an increase of incidental thyroid carcinomas (ICs), most of the ICs are any microcarcinoma (MC). The term refers to a CT, predominantly papillary, and smaller than or equal to 1 cm. The MC is characterized by a papillary heterogeneous clinical behavior ranging from small outbreak discovered accidentally after surgery than the cancer that manifests clinically with lymph node metastases in the neck or rarely systemic. METHODS: From January 2007 to June 2009, 1507 patients for benign disease were subjected to surgery. RESULTS: Histological examination confirmed the diagnosis of benignity in 1339 cases. In 168, however, we detected unexpected, incidental carcinoma (CI). In patients with CI receiving total surgery (TT), the next iteration we agree with the endocrinologist. In cases of lobectomia, was run TT and was heading endocrinology. Of the 168 patients with incidental CT, 147 had papillary carcinomas, 12 follicular carcinomas, 5 follicular variant papillary carcinomas, 2 oncocytic carcinomas, 1 uncertain malignancy. CONCLUSION: In our study has highlighted the lack of data (medical history, ultrasound, scintigraphic), they may portend the presence of a tumor in the specimen CI. In all patients with CI, the surgical indication was given for symptomatic disease, for impairment of thyroid function, for failure to respond to medical therapy or unable to continue. The IC is almost always a microcarcinoma, predominantly papillary, and smaller than or equal to 1 cm, has little biological aggressiveness and is susceptible to metabolic radioiodine therapy. On the basis of these data we feel reasonably acceptable to a close follow-up endocrine surgery, particularly in patients with multinodular disease and stress the need for a multi-specialized team.

Exercise and apulian hypocaloric diet affect adipokine changes and gastric banding-induced weight loss: A prospective study on severe obese subjects.

BACKGROUND: Adiponectin and Resistin correlate with insulin sensitivity and cardiovascular risk, respectively. This study aimed to identify lifestyle factors that modulate changes in Adiponectin and Resistin levels after gastric banding positioning (LapGB). MATERIALS AND METHODS: Before (T0), 3 months (T3), 6 months (T6), and 12 months (T12) after LapGB, serum Adiponectin and Resistin levels were evaluated in a single-centre prospective study including a cohort of 27 non-diabetic obese subjects (S-Ob, BMI ≥35 kg/m2). After surgery, a dietitian checked the adherence of S-Ob to an Apulian hypocaloric diet (aphypoD)/physical activity (phA) and, according to their high or low compliance to aphypoD/phA, S-Ob were included in group 1 (n = 14) or 2 (n = 13) respectively. Serum Adiponectin and Resistin were also measured in 10 healthy controls. RESULTS: At baseline, Resistin levels were significantly higher and Adiponectin levels significantly lower in S-Ob than in controls. After surgery, group 1 showed a 50.2% excess weight loss (%EWL), significantly decreased Resistin levels at T12 and increased Adiponectin levels at both T6 and T12 as compared with baseline. Group 2 showed 24.6 %EWL at T12, decreased Adiponectin levels at T6 and T12 as compared with baseline, but unaltered Resistin levels. After surgery, group 1 followed aphypoD/phA, while group 2 did not. CONCLUSIONS: LapGB fails to improve cardiovascular risk markers (Resistin) in S-Ob not improving lifestyle. Future studies might investigate these findings in a larger cohort and display whether aphypoD is more effective than other dietary intervention on cardiovascular risk in subjects undergoing LapGB or other Bariatric procedures.

Intestinal endometriosis: role of laparoscopy in diagnosis and treatment.

Endometriosis is a disease in women in which endometrial tissue is found in abnormal sites, frequently in the peritoneum and pelvic viscera. Endometriosis may therefore affect the genital organs, particularly the left ovary, or it may occur elsewhere in the abdomen, principally the digestive tract in the sigmoid-rectum. The difficulty of prompt diagnosis of nongenital endometriotic lesions, whose symptoms are usually nonspecific, and the inadequacy of traditional diagnostic approaches mean the disease has time to progress. A case report is used here to show the use of laparoscopy with immediate histologic examination for the prompt diagnosis and intraoperative treatment of intestinal endometriosis. For patients with extragenital endometriosis, laparoscopic resection offers immediate postoperative advantages but also gives gradual relief of symptoms and in some cases improves reproductive capacity; there is also less formation of adhesions in this disease, which by definition tends to cause them, often making a second look indispensable.

[Role of laparoscopy in acute obstruction of the small bowel: personal experience and analysis of the literature]. / Ruolo della laparoscopia nelle occlusioni acute del tenue: esperienza personale e analisi della letteratura.

Small bowel obstruction is caused by postoperative adhesions in most patients. The traditional surgical treatment has been laparotomy with adhesiolysis and possible resection of the ischaemic intestine. The laparoscopic approach has proved feasible but not without risks. We analysed our experience in the management of acute small bowel obstruction and then reviewed the literature in an attempt to identify the real role of laparoscopy. From January 2003 to June 2008, 19 patients operated on for small bowel obstruction were identified. We evaluated our performance in terms of the aetiology of the obstruction, operative time, length of postoperative hospital stay, conversion rate, and major morbidity and mortality. Postoperative adhesions were responsible for the occlusion in 13 cases; a single band was identified in 47% of patients (9 cases). Neoplastic disease (3 cases), a gallstone ileus, Crohn's disease and an internal hernia were the remaining cases. Laparoscopic treatment was only possible in 7 patients with single adhesions (77%), and a conversion was carried out in the remaining 12 cases (63%), including "laparoscopy-assisted" cases (6 cases). The duration of the intervention (89 +/- 21 min vs 135 +/- 27.5 min) and postoperative hospitalisation (3.6 +/- 1 days vs 6.25 +/- 1.6 days) were in favour of the completely laparoscopic group as compared to the laparoscopy-assisted group. A case of postoperative peritonitis due to bowel perforation required a second intervention. With an appropriate selection of patients, confirming the high incidence of the single adhesions responsible for the occlusion and the resulting high success rate of laparoscopy, we believe that only an initial laparoscopic approach can help identify such favourable situations.

[The conservative treatment in the splenic trauma]. / Il trattamento conservativo nel trauma splenico.

The Authors mention the historical evolution that led to consider the splenectomy as the ideal operation in patients with post-traumatic lesions of the spleen. They linger then on the actual knowledges about the pathophysiology of this organ that determined a substantial change of mind toward a conservative treatment, when possible, reporting data from the literature. In haemodynamically stable patients with splenic trauma, conservative treatment is recommended to preserve the spleen and prevent potentially lethal post-splenectomy infectious complications. A personal observation of a 17-years-old boy who suffered splenic hematoma after a trauma is referred. The decision to adopt a non-operative strategy allowed the preservation of the spleen without complications. Every therapeutic choice must be consequent to an accurate clinical evaluation of the single patient, either it suggests a surgical abdomen's exploration in urgency or the monitoring of the patient. This curative strategy is supported by the considerable contribution offered by sophisticated methods of radiological imaging and by the commercialization of substances with an high sticking power. Laparoscopic management of spleen trauma can be used once a positive diagnosis has been made. It is useful for assessing the degree of splenic injury. It is an effective procedure for the evaluation and treatment of haemodynamic stable patients with splenic injuries for whom non operative treatment is controversial. In conclusion conservative procedure for splenic lesions must find a growing consent, but warning against a too large widening of the indications for the conservative treatment beyond true safety conditions.

Diet After Cholecystectomy.

Patients with gallstones are often affected by alimentary disorders contributing to the onset of gallstones disease. Cholecystectomy can have nutritional and metabolic consequences in the short-term (diarrhea, abdominal pain and bloating) and in the long-term (increased Body Mass Index with metabolic syndrome, gastritis, liposoluble vitamin deficiency). Pathogenic mechanisms behind these disturbances are reviewed and the need for an early post-operative nutritional intervention based on low-lipid, high-fibers diet, is highlighted.

[Intestinal endometriosis: a case report]. / L'endometriosi intestinale: caso clinico.

Endometriosis is seldom of interest to the general surgeon, since it is generally an exclusively gynaecological condition. Atypical locations, however, do fall within the domain of general surgery. Extra-gynaecological endometriosis denotes an ectopic localization of functional endometrial tissue, a finding whose incidence is increasing due to the increasingly widespread use of laparoscopic procedures in chronic abdominal pain and infertility. We report our experience with complete laparoscopic management of deep pelvic endometriosis with isolated bowel involvement. In those patients without a past history of this condition, extragonadal endometriosis is rarely diagnosed preoperatively because the disease may mimic other abdominal pathologies. An accurate diagnosis can be provided by laparoscopy and especially by an intraoperative histopathological examination. Operative laparoscopy is a safe and effective method for treating intestinal endometriosis, significantly improves the patient's quality of life, is followed by resolution of the gynaecological and digestive symptoms and can enhance fertility.

Laparoscopy-assisted endoscopic mucosal resection in the colon: a preliminary report.

Endocopic mucosal resection of flat villous tumours or giant polyps (> 3 cm) may give rise to local complications such as haemorrhage or perforation because of the very thin wall of the colon, above all in the right half. Our aim was to evaluate whether laparoscopy-assisted endoscopic excision of flat villous tumours or giant polyps (> 3 cm) can be safely performed, avoiding critical septic complications and can also help in the selection of patients to be submitted to colonic resection without increasing morbidity or mortality. The procedure is a new minimally invasive therapeutic approach in selected cases with large, sessile or awkwardly located polyps. Unlike other techniques such as polypectomy, endoscopic mucosal resection completely removes the affected mucosa by resecting through the middle or deeper part of the submucosa. Another purpose of the procedure is to obtain specimens for accurate pathological staging. Our experience consisted in the treatment of two patients, one of whom with a laterally spreading tumour of the transverse colon with the suck and cut cap-assisted technique, and one with a large sessile polyp of the caecum with the lift and cut technique. The patients presented no complications and no recurrence was observed during the subsequent follow-up.

Management of intrahepatic biliary lithiasis after pancreatic cancer surgery.

Intrahepatic biliary lithiasis is fairly rare in western countries. In the case described here, liver stones had developed as a late consequence of biliary derivative surgery, which is well known to lead to this complication. However, this case is unusual because people who have undergone radical surgery for cancer of the head of the pancreas seldom survive long enough for liver stones to develop. Treatment for this 65-year-old woman, previously submitted to duodeno-cephalopancreatectomy, involved percutaneous balloon bilioplasty, with several passages in order to open the anastomosis. We then positioned two inner-outer biliary drains, through which repeated lavages were done. Finally, the patient underwent laser lithotripsy of the intrahepatic calculi and the fragments were cleared using a Dormia basket. Repeated cholangiographic monitoring showed progressively fewer stones, until the intrahepatic biliary tree was finally completely clear 120 days after the initial diagnosis. At the last follow-up, the patient was healthy, with normal blood values, considering her overall condition.

[Laparoscopic treatment of GISTs in our experience]. / Il trattamento laparoscopico dei GISTs: nostra esperienza.

Gastrointestinal stromal tumours are rare neoplasms originating from the connective tissue of the digestive tract and constitute most of the non-epithelial primitive digestive tumours. The origin from the interstitial cell of Cajal is appreciated because of this tumours constantly present the expression of the surface antigens CD34 and CD 117 which can be determined immunohistochemistry. In the majority of cases, GISTs are symptomatic and symptoms are most commonly related to mass effect or bleeding. Asymptomatic GISTs are often found incidentally on physical examination, radiologic imaging, endoscopy, laparotomy or laparoscopy. US endoscopy and fine needle aspiration with subsequent immunohistochemistry analysis afford the best diagnostic accuracy. In primary and localized GISTs surgery is always indicated and laparoscopic technique is feasible and is recommended as the treatment of choice for all the patients. Imatinib should be started in metastatic or recurrent disease and neoadjuvant imatinib is also experimental, although its use may be justified in unresectable or marginally resectable GIST. Sunitinib has recently been approved for patients with GIST principally those who fail imatinib therapy. Our experience is based on the study of 7 GISTs: only in 2 cases the neoplasm was found occasionally; in the other, symptoms were related to mass effect or bleeding. Laparoscopic tumour resection was then performed in all the patients. The definitive diagnosis of gastrointestinal stromal tumour, was made postoperatively by analysis of the histopathological and immunohistochemical findings. We confirmed constant high positivity for CD34 and for CD117. Even in the absence of unfavourable prognostic indicators, all patients are regularly followed-up.

A new clinical-ultrasound score to predict difficult videolaparocholecystectomies: A prospective study.

BACKGROUND: The gold standard treatment of symptomatic cholelithiasis is videolaparoscopic cholecystectomy (VLC). The aim of this study is to produce a predictive clinical ultrasound (US) score for difficult VLC to reduce the rate of conversion to open cholecystectomy surgery and intra and/or post-operative complications. METHODS: In this prospective study carried out in 2017 we enrolled 135 patients (pts) who underwent VLC in our General Surgery Unit. A specific pre-operative abdominal ultrasound scan was performed to assess gallbladder characteristics for each patient. All US and patients' characteristics were recorded in a standard form in order to obtain a preoperative score and were then added to the intra-operative variables. RESULTS: The analysis revealed a statistical significance between post-operative characteristics and parietal thickness, adhesions, stratifications and volume of gallstones. Comparing the degree of difficulty VLC assessed in the pre-operative stage to the intraoperative score, the sensitivity of the preoperative US scan test is 91.8% while the specificity is 76.7%. CONCLUSIONS: The variables which proved statistically significant in predicting a difficult cholecystectomy were: age, parietal thickness >3 mm, adhesions, stratifications, gallstones >2 cm and fixed gallstones. We have definitively defined a predictive score for difficult VLC for which a VLC is to be considered potentially difficult whenever it presents a pre-operative score equal or greater than 4 (and a "easy" one with a pre-operative score less than 4). These findings may prove helpful in further reducing the conversion rate and the rate of intra- and/or post-operative complications.

Laparoscopic appendectomy for the treatment of acute appendicitis: A single center experience.

AIM: The aim of our study is to compare the pre, intra- and post-operative variables of the two surgical techniques, to demonstrate if laparoscopic appendectomy can be considered safer and associated to better outcome. MATERIAL OF STUDY: A retrospective analysis of 175 patients has been carried out. Alvarado score, time of surgery, analgesic therapy and length of hospital stay calculated. Finally, postoperative complications were recorded. RESULTS: From January 2011 - April 2016 175 patients were enrolled: 128pts underwent laparoscopic technique and 47pts open technique. The average value of Alvarado score is lower in LA group than in OA group just as the average time of surgery and the use of post-operative analgesic therapy. DISCUSSION: LA has become the surgical technique mostly performed for the treatment of simple and complicated acute appendicitis. Our study shows that LA pts are younger with a statistically significant difference CONCLUSIONS: Most of the emergency appendectomies were performed via laparoscopic technique, especially in young patients. Laparoscopy is safer and associated to better outcome. KEY WORDS: Alvarado Score, Laparoscopic appendectomy, Open appendectomy.

[The acute cholecystitis: the operative timing for the laparoscopic approach]. / La colecistite acuta: il timing operativo con l'approccio laparoscopico.

The aim of this study is to evaluate the results of early cholecystectomy in patients with acute cholecystitis. In the past, acute cholecystitis was a contraindication to laparoscopic cholecystectomy because of the greater risk of injury to the biliary duct, but acute gallbladder inflammation was a contraindication to open cholecystectomy, too. With greater experience and new technology, laparoscopic cholecystectomy is today the gold standard in the treatment of acute cholecystitis, in empyema and gangrenous cholecystitis. In recent years, attention has turned to surgical timing, rather than surgical management--open versus laparoscopy--because there is no advantage in delaying cholecystectomy for acute cholecystitis. In our experience, we always choose laparoscopic technique in all the patients without general contraindications to mini-invasive surgery and operate as soon as possible in a patient with unfavourable conditions. We believe that the patient must be quickly stabilized with preoperative medical procedures, and surgical treatment must be performed within 72-96 hours after the onset of symptoms. During this period, laparoscopic approach allows a reduction of operative time, operative risk and the conversion rate with medical and economic advantages.

Laparoscopic and Open Surgical Treatment in Gastroduodenal Perforations: Our Experience.

INTRODUCTION: Peptic ulcer perforation (PPU) is a common surgical emergency and the mortality rate ranges 10% to 40%, especially in elderly patients. Laparoscopic repair achieved encouraging results. MATERIALS AND METHODS: We enrolled patients performing surgical repair for PPU from January 2007 to December 2015 in our surgical unit. The aim of this retrospective observational study was to compare the results of PPU laparoscopic repair with open technique. The following characteristics of patients were evaluated: age, sex and American Society of Anesthesiologists classification. The site and the diameter of perforation were recorded: gastric, pyloric, duodenal, and the location on the anterior or posterior wall. RESULTS: In total, 59 patients (39 males and 20 females) with a mean age of 58.85 years (±SD) were treated surgically. Laparoscopic repair was accomplished in 21 patients. The mean operative time for laparoscopic repair was 72 minutes (±SD), significantly shorter than open repair time (180 min ±SD). The results demonstrated that laparoscopic repair is associated with a shorter operative time, reduced postoperative pain (4.75 vs. 6.42) and analgesic requirements, a shorter hospital stay (7.5 vs. 13.1), and earlier return to normal daily activities. DISCUSSION: Laparoscopic surgery minimizes postoperative wound pain and encourages early mobilization and return to normal daily activities. The benefit of early discharge and return to work may outweigh the consumable cost incurred in the execution of laparoscopic procedures. CONCLUSIONS: Complications in both procedures are similar but laparoscopic procedure shows economic advantages for reducing postoperative hospital stay, postoperative pain, and for a good integrity of abdominal wall.

Perineal Paget's disease: A rare disorder and review of literature.

INTRODUCTION: Extramammary Paget's disease (EMPD) occurs commonly in perineum, vulva and perineal region and is considered as a complex disorder due to different clinical and histological features. PRESENTATION OF CASE: A 61 years old woman had a dermatologic evaluation for anal itch and underwent a skin biopsy with diagnostic of Paget disease in perianal region. Pelvic magnetic resonance showed a huge tumor which involved skin, derma and gluteus and she firstly refused any surgical treatment. One year later, because of increasing of the tumor and bleeding, she underwent the surgical procedure with a complete excision, resection of the skin of the anus, inguinal lymphadenectomy and left colostomy. Because of lymph nodes metastasis, a VLS Miles was sequentially performed. She started oncological follow up that showed liver, lung and pelvic metastasis. She survived for 24 months after surgery. DISCUSSION: In literature, less than 200 cases of perineal Paget's disease have been reported. EMPD in some cases has an associated adenocarcinoma, which has been associated with a worse prognosis and high mortality. Wrong diagnosis and a superficial consideration of a benign evolution should be considered as the first mistake in clinical practice. CONCLUSION: Our surgical approach is considered in literature as the best one for those cases, followed by the oncological treatment. Those patients need to be better studied and more attention should be paid to the clinical presentation.

Laparoscopic management of pancreatic cancer. Our experience.

AIM: Minimally invasive techniques have a definite role in the surgical treatment of several gastrointestinal tract cancers but there is still no widespread use of the laparoscopic approach for cancers of the head of the pancreas. The aim of this retrospective study is to review our experience from 2003 to 2013 in the management of pancreatic cancer with particular emphasis on the clinical application of minimally invasive techniques. METHODS: One hundred fifty-eight pancreatic cancer patients (median age 69,7±12,6 years) with obstructive jaundice were enrolled in our study. One hundred eighteen (74,7%) had an endoscopic biliary stent, 68 patients (43,03%) were eligible for surgery. Only 22 of the patients eligible for surgical intervention underwent pancreaticoduodenectomy (PD): 14 had open PD and 8 had laparoscopic PD (LPD). Thirteen of the PD patients had a pylorus-preserving procedure (8 open and 5 laparoscopic procedures) whereas in 9 the pylorus was not preserved (6 open and 3 laparoscopic procedures). The other 46 patients had un-resectable tumors and 34 of them underwent palliative surgery consisting of gastrojejunal and hepatojejunal anastomosis (18 open and 6 laparoscopic procedures), and gastrojejunal anastomosis in 10 patients (4 open and 6 laparoscopic procedures). Ten patients had only explorative laparoscopy and 2 only explorative laparotomy. RESULTS: The resectability rate was 13,9%. The median age in patients treated with an endoscopic biliary stent was significantly higher than in those who underwent surgery (73,2±13,3 years vs 64,4±9,6 years; p < 0,05). Operative time in LPD patients was significantly longer than in PD patients (521±68 minutes vs 381±88 minutes; p<0.05). The hospital stay of patients who underwent PD was significantly longer than that of those who underwent palliative surgery (27±4 days vs 10±5 days; p < 0.05). in PD patients the morbidity rate was 22,72 % and the mortality rate 4.5%. CONCLUSIONS: In recent years laparoscopic surgery has become very important in oncologic surgery because it is minimally invasive and reduces postoperative complications and because there is sufficient evidence based data showing that results in terms of complications and survival are as good as the results of conventional surgery. However the learning curve for laparoscopic cancer surgery of the head of the pancreas is steep and our results indicate that in LPD operative time is significantly longer than in PD, and moreover the laparoscopic approach is not associated with a shorter hospital stay. Therefore LPD should be performed only in well-established laparoscopic and oncological centers with a multidisciplinary team. KEY WORDS: Laparoscopy, Pancreatic cancer, Pancreaticoduodenectomy.

A case of giant retroperitoneal liposarcoma.

A 44-year-old female patient presented to us with fever and increased abdominal girth. A CT scan showed a very large retroperitoneal mass displacing the right kidney. At operation three enormous retroperitoneal tumours displacing the ascending colon and the right kidney and compressing the inferior vena cava were removed. Histopathological examination revealed a myxoid retroperitoneal liposarcoma.
