RESUMO
BACKGROUND: Central pancreatectomy (CP) is a parenchyma-sparing surgical procedure that enables the removal of benign and/or low-grade malignant lesions from the neck and proximal body of the pancreas. The aim of this review was to evaluate the short- and long-term surgical results of CP from all published studies, and the results of comparative studies of CP versus distal pancreatectomy (DP). METHODS: Eligible studies published between 1988 and 2010 were reviewed systematically. Comparisons between CP and DP were pooled and analysed by meta-analytical techniques using random- or fixed-effects models, as appropriate. RESULTS: Ninety-four studies, involving 963 patients undergoing CP, were identified. Postoperative morbidity and pancreatic fistula rates were 45·3 and 40·9 per cent respectively. Endocrine and exocrine pancreatic insufficiency was reported in 5·0 and 9·9 per cent of patients. The overall mortality rate was 0·8 per cent. Compared with DP, CP had a higher postoperative morbidity rate and a higher incidence of pancreatic fistula, but a lower risk of endocrine insufficiency (relative risk (RR) 0·22, 95 per cent confidence interval 0·14 to 0·35; P < 0·001). The risk of exocrine failure was also lower after CP, although this was not significant (RR 0·59, 0·32 to 1·07; P = 0·082). CONCLUSION: CP is a safe procedure with good long-term functional reserve. In situations where DP represents an alternative, CP is associated with a slightly higher risk of early complications.

The aim of this study was to establish the role of surgery in the treatment of retroperitoneal liposarcomas. Data concerning 28 patients submitted to surgery for retroperitoneal liposarcoma in our department over the period from 1972 to 1999 were reviewed retrospectively and analysed. Seventy-four operations were performed; in 54% of the operations it was necessary to resect contiguous organs (kidney 60%, colon 50%, adrenal gland 35%). In 89%, grossly curative resection was achieved at the first operation; 20 patients had at least one local recurrence after first operation (median time interval: 22 months). The mean follow-up was 80 months; median survival time was 51 months and 5-year actuarial survival time 51%. Patients with low-grade liposarcoma showed a statistically significant improvement (P < 0.001) in median survival (153 months) versus those with medium- (37 months) and high-grade sarcomas (8 months). At present surgery is still the treatment of choice in the treatment of primary and recurrent liposarcoma; in the case of low-grade liposarcomas especially, an aggressive surgical approach can result in long-term survival.

BACKGROUND/AIMS: Primary distal bile duct adenocarcinomas (DBDAs) are unusual neoplasms, necessitating pancreaticoduodenectomy for cure. The aims of this study were to evaluate the prognostic importance of lymphatic and perineural invasion, long-term outcome of patients after resection, and differences in outcome with hilar cholangiocarcinoma and pancreatic carcinoma. METHODS: The medical records and histopathological slides of 15 patients (8 men and 7 women) with documented DBDA after curative pancreaticoduodenectomy were reviewed. RESULTS: Nine standard and 6 pylorus-preserving pancreaticoduodenectomies were performed. TNM staging included 1, 3, 2, 8, and 1 patient in stages I, II, III, and IVA and IVB, respectively. Lymphatic and perineural invasion was present in 4 (27%) and 9 (60%) patients, respectively. With multivariate analysis only serum bilirubin was a significant prognostic factor. Median survival was 21 months, and 2- and 5-year actuarial survivals were 40 and 20%, respectively. Median survival with adjuvant therapy (n = 6) was 21 months, with 5-year survival of 33%. Five-year actuarial survivals when lymphatic or perineural invasion was present were 0 and 11%, respectively. CONCLUSION: DBDA is aggressive, but entails a better prognosis than pancreatic ductal or more proximal bile duct carcinoma. Lymphatic and/or perineural invasion worsen survival.

Esophageal perforation is a serious complication of pneumatic dilatation. We studied the cases of 4 patients (2 men and 2 women, mean age 58 years, range 56-62) who had surgical treatment for achalasia, two of which had had previous dilatation. The main symptoms were pain and dyspnea. Pneumomediastinum was present in all patients, pleural effusion in 2 and cervical emphysema in 1. Esophagographic results showed evidence of perforation in all four cases and gastric patches were surgically placed on the esophageal tear within 12 hours. Three patients received enteral nutrition for an average of 13 days. Mean hospital stay was 14 days. No post-operative complications were exhibited although one patient did develop gastroesophageal reflux 3 months later and underwent surgery to repair a hernia in the thorax 5 years later. Early and aggressive treatment is considered the best therapy and the gastric patch, in our opinion, is an effective and reliable technique for esophageal perforation repair in achalasia patients.

BACKGROUND: Extended pancreaticoduodenectomy (EPD) with retroperitoneal lymphatic, neural, and connective clearance has been proposed to improve survival in patients with carcinomas of the head of the pancreas. The open questions are: does EPD allow better staging of the tumor? Does it reduce local recurrences? And does it improve survival? METHOD: We treated 26 patients by EPD between January 1994 and September 1996. Eighteen patients had pancreatic ductal carcinoma, 7, periampullary carcinoma; and 1, intraductal papillary mucinous carcinoma. RESULTS: The pancreatic cancers were International Union against Cancer (UICC) stage I in 3 patients, stage III in 14, and stage IV in 1. Two patients with stage III disease would have been considered as having stage I without EPD. Pancreatic cancer and periampullary carcinoma patients had a 3-year actuarial survival of 32% and 86%, respectively. At a mean follow-up time of 22.5 months (range, 6-39 months), 3 pancreatic cancer patients (16.6%) had loco-regional recurrences, 6 patients (33%) had distant metastases, and 1 (5.5%) had distant and loco-regional recurrences. Only 1 of 7 patients with periampullary carcinoma had distant metastasis 20 months after resection. CONCLUSION: EPD seems to decrease the rate of local recurrences and allows more correct staging. The intermediate survival results are encouraging but a definitive conclusion awaits longer follow-up.

The herniation of abdominal viscera in the thorax can immediately follow diaphragmatic rupture or be delayed even years after the injury. The herniated viscera can strangulate; this consequence may lead to a dangerous misdiagnosis which could be lethal for the patient. Radiological procedures, serial chest X-ray studies, CT and MRI scans are mandatory to confirm diagnosis. The insertion of a naso-gastric tube is a very helpful method in ruling out hypertensive pneumothorax in the presence of an air-fluid level in the thorax. We report 2 cases of strangulated traumatic hernia of the diaphragm occurring just a few hours (case 1) and 18 months (case 2) after the trauma. During thoracotomy, a rupture of the left diaphragmatic cupola was demonstrated with herniation of the stomach in case 1, the stomach, spleen and transverse colon in case 2. No postoperative mortality or morbidity were detected.

Pancreatic Non Ductal-Adenocarcinoma Neoplasms (PNDAN) represent about 20% of pancreatic and periampullary tumors and should be considered in differential diagnosis with ductal adenocarcinoma in the presence of isolated pancreatic mass. From January 1992 to December 1998, 238 patients were operated on for pancreatic and periampullary masses. Fifty-five patients had PNDAN: 24 endocrine tumors, 7 serous cystadenomas, 6 intraductal papillary-mucinous tumors, 5 acinar carcinomas, 4 mucinous cystadenomas, 3 metastatic tumors, 2 cystic papillary tumors, 2 solid cystadenocarcinomas, 1 neurilemmoma, and 1 pancreatoblastoma; 19 were benign and 36 were malignant or borderline tumors. A correct preoperative diagnosis was obtained in 58% of the cases. In all other cases, diagnosis was achieved intraoperatively. Major (18 pancreaticoduodenectomies, 17 left splenopancreatectomies, 1 total pancreatectomy) and minor resections (5 central pancreatectomy, 10 enucleations) were performed; curative surgical operations were carried out on 39/55 patients (curative resectability: 71%). Operative mortality and morbidity were 1.8% and 21.8%, respectively. Three and 5-year actuarial survival for malignant or borderline PNDANs are 65% and 40% versus 31% (3-year) for ductal adenocarcinoma of pancreatic head treated by pancreaticoduodenectomy (p-value = 0.03). We believe that pancreatic masses that are not ductal adenocarcinomas, can be aggressively resected even if large in size, resulting in a better outcome than ductal adenocarcinoma itself.

Stromal tumors (GIST) represent 5% of gastric neoplasms. Twenty-five patients with GIST underwent surgical operation: the tumor was benign, malignant, and borderline in 11, 12, and 2 cases, respectively. Main symptoms were abdominal pain (36%), and digestive haemorrhage (32%); 4 patients (16%) complained of abdominal mass. In 5 patients the diagnosis was incidental. Surgical operations (12 local resections, 9 partial gastric resections, and 4 total gastrectomies) were macroscopically curative in all the patients. In 3 patients the resection was extended to liver (1 case), spleen, pancreatic body-tail, and left kidney (1 case), and diaphragm (1 case) because of contiguous involvement of these organs. Postoperative mortality and morbidity were 4% and 20%, respectively. A patient with benign GIST passed away 36 months after operation because of breast cancer disease; other 9 patients are alive from 3 months to 25 years after operation. Three patients with low grade malignant GIST are well at mean follow up of 53 months. The 9 patients with high grade neoplasms are all dead (median survival time: 18 months). The 2 patients with borderline tumors are alive without evidence of disease at 3 and 8 years.

Tumors located in the neck of the pancreas that are not small and superficial enough to be enucleated are usually resected with a pancreaticoduodenectomy or left splenopancreatectomy. Such operations may cause digestive disorders, glucose intolerance, and late postsplenectomy infection. Central pancreatectomy is a segmental resection whereby the cephalic stump is sutured and the distal stump anastomosed with a Roux-en-Y jejunal loop. The purpose of this study was to evaluate whether central pancreatectomy has a place in pancreatic surgery. Thirteen patients with the following tumors underwent central pancreatectomy: five endocrine tumors, one mucinous and six serous cystadenomas, and one solid cystic-papillary tumor. Mean operative time was 250 minutes. Operative mortality was zero. Complications occurred in three patients (23%). At mean follow-up of 68 months, no recurrences were found. Postoperative oral glucose tolerance, pancreolauryl, and fecal fat excretion tests were normal in all patients. We believe that central pancreatectomy does have a place in pancreatic surgery; it is a reliable technique for benign or low-grade malignant tumors and has a surgical risk similar to that of standard operations. Its principal advantage is that it preserves pancreatic parenchyma and the anatomy of the upper gastrointestinal and biliary tract and the spleen better than pancreaticoduodenectomy or distal pancreatic and splenic resection.

Inflammatory pseudotumors of the liver (IPL) are extremely rare focal lesions of the parenchyma. Up to now, the ethology of IPL has not been completely understood. Usually the clinical presentation is with fever, chills, hepatic mass. The fine needle biopsy shows a large amount of inflammatory cells, while the most common imaging techniques are not specific and do not reach a definitive preoperative diagnosis between a benign and a malignant tumor. From the examination of the Literature, the Authors found a mortality rate of 40% among patients treated by antibiotic therapy, while surgical procedures were successful in all but one case. Moreover, in Authors' case, successfully treated by hepatic resection, the preoperative diagnostic procedures were not helpful in differential diagnosis with a malignant lesion. For these reasons, the Authors believe surgery is the best therapeutic choice in case of a suspected IPL without an early clinical resolution after antibiotic therapy.

The diagnosis of traumatic hernia of the diaphragm can be obtained at the time of injury or months-years after the trauma. The Authors report a case of traumatic hernia of the diaphragm, diagnosed 3 years after a blunt thoracic trauma in a 47-year-old man. The patient was admitted to the hospital for a pneumothorax caused by perforation of the herniated colon. He underwent colonic resection and reduction of the herniated viscera but unfortunately he died of septic shock on the 40th postoperative day. Pneumothorax is a very rare complication of traumatic diaphragmatic hernia and few cases are reported in literature. The diagnosis in the delayed phase is not easy since the correlation with the trauma is not always clear.

AIM: Retrospective evaluation of 19 diaphragmatic ruptures due to blunt trauma. MATERIALS AND METHODS: We collected all patients with thoracic and/or abdominal blunt trauma who were admitted to the department of surgery (Clinica Chirurgica and Chirurgia generale C) from 1970 to 1995. We selected patients with ascertained diaphragmatic rupture. RESULTS: We considered 17 cases of TDR (15 males and 4 females). Mean age was 38 years (range 16-67). Radiologic findings were consistent with TDR in 10 cases out of 17 (58.8%). Right hemidiaphragm was injured in 6 cases (31.6%). 10 patients (52.6%) presented at operation with intrathoracic visceral herniation. 8 patients underwent laparotomy, 7 both laparotomy and thoracotomy, 4 thoracotomy alone. Perioperative mortality was 15.7% (3 patients). DISCUSSION AND CONCLUSIONS: The clinical features were complicated by a large number of associated lesions; radiologic diagnosis is comparatively easy if visceral herniation into the thorax is present, repeated radiologic examinations facilitate diagnosis. The surgical access is determined by concomitant associated injuries which may require urgent operation.

The poor prognosis of pancreatic carcinoma after resection is related to distant metastases and local recurrence that is characterized by a strong tendency to infiltrate the retroperitoneal tissue and spread along the neural plexuses and lymph nodes. Thorough clearance of these tissues around the celiac and mesenteric axes, aorta, and inferior vena cava from the diaphragm to the inferior mesenteric artery (extended pancreaticoduodenectomy may lower the rate of local recurrence, but the procedure has been criticized for its higher morbidity and mortality. Our aim was to compare extended pancreaticoduodenectomy (EPD) with standard pancreaticoduodenectomy (SPD) in terms of postoperative morbidity and mortality. Data from 47 patients who underwent either EPD (n=24) or SPD (n=23) between November 1992 and October 1995 were retrospectively analyzed. Preoperative laboratory findings, operative risk (according to the American Society of Anesthesiologists classification), type of operation (classic Whipple vs. pylorus-preserving Whipple), operative time, intraoperative blood and plasma transfusion, postoperative morbidity and mortality, and postoperative hospital stay were scrutinized. The results showed that all of the parameters considered were similar in the EPD and SPD groups (intraoperative blood transfusion 800+/-490 ml vs. 700+/-586 ml, postoperative mortality 0% vs. 4.3%, overall morbidity 45.8% vs. 47.8%, surgical morbidity 37.5% vs. 34.7%, and postoperative hospital stay 16+/-8.1 days vs. 17+/-13.1 days. These two groups differed only in the operative time, which was significantly longer for EPD than for SPD (360+/-68.9 minutes vs. 330=66.9 minutes, P=0.02). Although the operative time is increased with EPD, there does not appear to be an increase in intraoperative complications, postoperative morbidity and mortality, or postoperative hospital stay with this procedure. However, definitive confirmation of these results can only be provided by a prospective randomized study.

Hepatoblastoma in adults is a rare malignancy that presents in the epithelial or mixed epithelial-mesenchymal variants. We report two cases, the former representing the epithelial and the latter the mixed type. A 21 year-old woman with epigastric pain had abdominal ultrasound and CT scans showing a large hepatic mass. A right trisegmentectomy was performed. The first and second recurrences were treated by resection. The third recurrence was treated by hepatic transarterial chemo-embolization, systemic chemotherapy and 19 percutaneous alcohol injections. A careful follow up by abdominal ultrasound and CT scans was able to detect the recurrence at an early stage. The patient is well at 151 months. A 39 year-old man with epigastric pain and dyspepsia had upper-GI series and abdominal CT scan showing a left hepatic mass involving the stomach. Liver resection and Billroth II hemigastrectomy were performed. A recurrence involving the left hepatic lobe, the spleen and the remaining stomach occurred 15 months later and the patient died from multi organ failure. Surgery is the treatment of choice of hepatoblastoma in adults. Recurrences can also be treated aggressively by surgical resections if no extrahepatic organs are involved. Other therapeutic modalities can be attempted whenever surgery is not possible.

BACKGROUND: Since the role of a hiatal hernia in the pathophysiology of gastroesophageal reflux disease (GERD) has not been fully elucidated, we studied the effects of hiatal hernias on the function of the lower esophageal sphincter (LES) and esophageal acid clearance. PATIENTS AND METHODS: Ninety-five consecutive patients with GERD diagnosed by 24-hour pH monitoring underwent upper gastrointestinal series (UGI), endoscopy, and esophageal manometry. Based on the presence (H+) or absence (H-) of a hiatal hernia on UGI series, they were divided into two groups: H+ (n = 51) and H- (n = 44). Then, using the size of the hiatal hernia, the H+ group was divided into three subgroups: I, H < 3 cm (n = 31); II, H 3.0 to 5 cm (n = 14); and III, H > 5 cm (n = 6). RESULTS: Esophageal manometry showed that patients with larger hiatal hernias (groups II and III) had a weaker and shorter LES and less effective peristalsis compared to patients with a small or no hiatal hernia. Prolonged pH monitoring showed that patients with larger hiatal hernias were exposed to more refluxed acid and had more severely abnormal acid clearance. Endoscopy showed more severe esophagitis among patients with GERD and hiatal hernia compared with GERD patients without hiatal hernia, and the degree of esophagitis was proportionate to the size of the hernia. CONCLUSIONS: Among patients with proven GERD, those with a small hiatal hernia and those with no hiatal hernia had similar abnormalities of LES function and acid clearance. In patients with larger hiatal hernias, however, the LES was shorter and weaker, the amount of reflux was greater, and acid clearance was less efficient. Consequently, the degree of esophagitis was worse in the presence of a large hiatal hernia.

One hundred and fourteen consecutive patients with unresectable hepatocellular carcinoma were treated by chemoembolization using ethiodized oil (Lipiodol), anticancer agents. Ninety patients had concomitant chronic liver disease. Hepatocellular carcinoma (HCC) was diagnosed by US, contrast enhanced CT, fine needle biopsy and alpha-feto-protein level. Admission criteria were as follows: tumor confined to the liver with or without hilar nodal involvement, Child class A or B, white blood cell count above 2.000/mmc and platelet count above 75,000/mmc. All the patients underwent angiographic chemoembolization with Lipiodol and anticancer agents. In 98 patients we performed transcatheter hepatic arterial embolization (TAE) with Gelfoam or for Ivalon sponge. In 16 patients TAE was not performed because of portal thrombosis (7 cases) or technical reasons (9 cases). Mitomycin was used in 40 patients and dihydroxyanthracenedione (DADH) in 58 patients. In the TAE group 83 patients were Child A and 15 Child B. In 27 patients HCC was mononodular whereas in 71 it was multinodular. In 41 patients the tumor was more than 5 cm in diameter (in multinodular tumors only the larger lesion was taken into account). In 56 patients chemoembolization plus TAE was repeated. Seven patients died within one month after treatment: two from myocardial infarction, two from liver failure, two from digestive haemorrhage and one from necrotizing pancreatitis. Long-term survival rates were investigated in relation to prognostic factors: anti-cancer agent, number of nodes, tumor size and Child stage using Kaplan-Meier method. Survival rate at 12, 24 and 36 months are 64%, 38%, and 30% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

One hundred and thirteen patients with metastases from colorectal carcinoma underwent liver resection. The authors report their experience with respect to 23 repeated hepatic resections (or metastases from colorectal carcinoma). The calculated actuarial survival from the first operations is 100% at 12 months, 67% at 24 months, 48% at 36 months and 26% at 60 months. In 90 patients who underwent a single liver resection during the same period, 76% were alive at 12 months, 40% at 24 months, 27% at 36 months and 14% at 60 months (p = 0.03). Survivals calculated from the second operation were 67% at 12 months, 41% at 24 months and 11% at 35 months. There was no operative mortality with morbidity added to that of the first operation. None patients had extrahepatic disease at the second operation: this was resected. Seven patients were treated with neo adjuvant chemotherapy; six with systemic adjuvant chemotherapy; in one this was associated with loco-regional chemotherapy. The number of lesions (single versus multiple), the presence or absence of extrahepatic disease, neo-adjuvant chemotherapy and adjuvant chemotherapy did not seem to influence the prognosis. Average survival calculated from the appearance of the first metastasis in the liver is better in patients with a synchronous lesion compared to the patients with a metachronous lesion (48.1 months versus 29.3). The authors claim that surgery is indicated, when technically possible, in the hepatic recurrence of disease. The results are not as good as those obtained following the first liver resection, with a probability of earlier recurrence of disease.(ABSTRACT TRUNCATED AT 250 WORDS)
