Impact of a portal/superior mesenteric vein resection during pancreatico-duodenectomy for pancreatic head adenocarcinoma.

AIM: The impact of venous resection (VR) in pancreatico-dudenectomy (PD) for pancreatic adenocarcinoma (PDAC) is controversial. The aim of the study is to comparatively assess the postoperative outcomes after PD with and without VR for PDAC and to identify predictors of morbidity and survival in the subgroup of PD with VR. METHODS: The data of 51 PD with VR were compared with those of 183 PD without VR. Binary logistic regression and Cox survival analyses were performed. RESULTS: Both the operative time and estimated blood loss was significantly higher in the VR group (P<0.001). A trend towards an increased 90-day mortality (9.8% vs. 5.5%) and severe morbidity (20% vs. 13%) was observed when a VR was performed (P ≥0.264). The median overall survival time after the PD with and without VR was 13 months and 17 months, respectively (P=0.845). The absence of histological tumor invasion of the VR was found as the only independent predictor for a better survival (HR=0.359; 95% CI 0.161-0.803; P=0.013). CONCLUSION: A PD with VR can be safely incorporated in a pancreatic surgeon armamentarium. However, the trend towards increased mortality and severe morbidity rates should be expected, along with higher operative time and blood loss, compared with PD without VR. Associated VR does not appear to significantly impair the prognosis after PD for PDAC; however, histological tumor invasion of the VR has a negative impact on the survival.

Surgical treatment of chronic pancreatitis--a 14 years experience.

BACKGROUND: Operative treatment of chronic pancreatitis is indicated for patients with intractable pain after failed medical and endoscopic treatment, or in the presence of complications of the disease. AIMS: This study evaluates a single-center experience with operative management of chronic pancreatitis over a period of time of 14 years, regarding indication, surgical technique, early and late results. PATIENTS AND METHODS: The records of 265 consecutive patients who underwent surgery for chronic pancreatitis between 1995 and 2008 were retrospectively reviewed and analyzed. Long-term outcomes were assessed by patient survey, with a median follow-up of 40 months. RESULTS: 265 patients underwent 275 operations for chronic pancreatitis with the main indication abdominal pain (46.8%), followed by suspected malignancy in 24.8% and recurrent episodes of acute pancreatitis in 18.6%. Resection procedures 54.5% (150), drainage procedures 1.09% (3), bypass and denervation procedures 44.36% (122) and exploratory laparotomy 3.27% (9) were performed with an overall morbidity of 22% and an in-hospital mortality rate of 2.64%. After a median follow-up of 40 months survival information was available for 137 patients (51.69%) with a 5-and actuarial survival rate of 74.7% and quality of life improvement in most patients, especially in the resected group. CONCLUSION: Our results suggest that in chronic pancreatitis the type of surgery has to be individualized in each patient (resection VS drainage) and organ preserving operations are safe and effective in providing long-term pain relief and in treating CP-related complications

[Spleen preserving subtotal pancreatectomy for chronic pancreatitis: case report]. / Pancreatectomie subtotala cu prezervarea splinei pentru pancreatita cronica: prezentare de caz.

Subtotal pancreatectomy is an exceptional solution for the pain in chronic pancreatitis affecting the whole pancreas, which evolves with non-dilated Wirsung duct or in cases in which drainage procedures fail to achieve improvement of symptoms. If it is possible to avoid splenectomy, this type of surgical procedure enters in the modern concept of treatment of chronic pancreatitis named "organ sparing", basically being a Beger procedure combined with a distal pancreatectomy with spleen preservation. The case reported here is of a young male (29 years old) with idiopathic chronic pancreatitis progressively affecting the whole pancreas which had the main symptom the resistant pain to medical and non-resectional surgical treatment (left thoracoscopic splanchnicectomy at 4 years after diagnosis); at 8 years after diagnosis the pain becomes almost permanent, a cystic tumor is evolving in the body of pancreas and CA 19-9 tumor marker reaches values over 100 U/mL. In this context it was decided to perform a spleen-preserving subtotal pancreatectomy 95% (near total pancreatectomy) as the last therapeutic resource. The postoperative course was complicated with a biliary leak treated conservative and the patient was discharged in the 54th postoperative day. After 12 months the results are good regarding pain control, serum glucose levels and quality of life.

[Pancreaticoduodenectomy in elderly patients--a safe operation?]. / Duodenopancreatectomia cefalica la vârstnici--operatie sigura?

The aim of this study was to analyze the impact of age in mortality and morbidity after duodenopancreatectomy (DPC), setting the age of 70 as a cut-off. A retrospective study was made of two groups of patients (under 70 and over 70 years old) who underwent DPC in the Center of General Surgery and Hepatic Transplantation, Fundeni, Bucharest between 2001 and 2006 for malignant and benign tumors of the pancreatic head, distal biliary tract, duodenum, Vater's ampulla and chronic pancreatitis. 245 DPC were performed, 207 in patients under 70 years old (group A) and 38 in patients over 70 years old. Postoperative global morbidity rate was 58% in group B vs 49,9 % in group A. Postoperative mortality rate was 5,2% in group B and 4,8 % in group A. No significant differences were recorded in survival when comparing the two groups, both in pancreatic head cancer or distal biliary tract cancer. Under these circumstances, increased age is not determining an increase in postoperative mortality after DPC, but is associated with a higher risk of postoperative medical complications.

[Recurrent benign cystic peritoneal mesothelioma]. / Mezoteliom multichistic peritoneal recidivat.

The benign cystic peritoneal mesothelioma (BCPM) is a rare neoplasm affecting mainly females at reproductive age. The natural history and physiopathology of the BCPM are not entirely known. It is mainly characterized by the lack of malignant elements, no tendency to metastasis and by a pervasive tendency to generate local recurrences after surgical removal. The clinical manifestations are insidious, uncharacteristic; the benign cystic peritoneal mesothelioma is often discovered during a surgical procedure addressing another condition. Imaging tests can raise the suspicion of BCPM but the diagnostic can only be confirmed by histopathological examination corroborated with an immunohistochemical analysis. There are no long term studies dictating a single therapeutic attitude but a high risk of local recurrences and the possibility of transformation into malignant mesothelioma have lead to the current tendency towards an aggressive treatment of the tumor. We present the case of a recurrent benign cystic peritoneal mesothelioma in a 40 years old female patient, emphasizing the therapeutic approach and the role of radical surgery in the treatment of BPCM.

[Liver resection after downstaging with systemic chemotherapy in a case of a multicentric hepatocellular carcinoma with virus B cirrhosis]. / Rezectie hepatica dupa downstaging prin chimioterapie sistemica intr-un caz de hepatocarcinom multicentric grefat pe ciroza VHB.

Hepatocellular carcinoma is often diagnosed in an advanced stage when curative therapeutical options are limited, especially with coexisted cirrhosis. Downstaging-resection plays a role in improving prognosis of unresectable hepatocarcinoma. We report the case of a 27 years old woman with multicentric hepatocellular carcinoma and virus B cirrhosis, portal vein thrombosis with systemic chemotherapy followed be hepatic resection--left hepatectomy and lymph node dissection for the remaining tumor. Postoperative outcome was uneventful, the patient being alive at 22 month after diagnosis, without recurrence. Combined modalities with systemic chemotherapy and surgical resection can achieve complete clinical remission and long-term control of disease in patients with unresectable hepatocarcinoma.

[Resection of the celiac axis increase resectability rate in locally advanced pancreatic body and gastric tumor]. / Rezectia de trunchi celiac--factor de crestere a rezecabilitatii in neoplasmele pancreatice si gastrice local avansate.

Celiac axis involvement in locally advanced neoplasia was considered in the past a criteria of non resectability. Carcinoma of the body and tail of the pancreas is often diagnosed at an advanced stage or metastatic stage. Gastric carcinoma (particularly antral localization) can also be locally invasive. Celiac axis can be invaded in both neoplasias. In order to increase resectability rate in those two types of neoplasia celiac trunk resection was proposed (en bloc with distal pancreatectomy, loco-regional lymph node excision with or without total gastrectomy). We report our experience on 3 patients and some considerations about this surgical technique from medical literature.

Digestive tumor bank protocol: from surgical specimens to genomic studies of digestive cancers.

Cancer is a complex polygenic and multifactorial disease, resulting from successive dynamic changes in the genome of somatic cells and from the accumulation of molecular alterations in both tumour cells and host cells. For the majority of cancers, including many malignancies of the gastrointestinal tract, our current means of diagnosis and treatment of the tumors are grossly insufficient. In recent years the development of several gene expression profiling methods such as comparative genomic hybridization (CGH), differential display, serial analysis of gene expression (SAGE) and DNA arrays, together with the sequencing of the human genome, has provided an opportunity to monitor and investigate the complete cascade of molecular events leading to tumor development and progression. Given the central role played by surgeons in the current management of patients with solid cancers, it is of paramount importance for them to know the principles characterizing this laboratory tools to critically assess the results originating from this biotechnology. We describe in this article the scientific partnership between Fundeni Clinical Institute Bucharest, Romania and RNtech Company, Paris, France for the development of a center of biological resources (Biobank) as well as the standardized protocol of working with the biological samples, the ongoing projects and the future perspectives.

[Central pancreatectomy--indications, technique, outcomes]. / Pancreatectomia centrala--indicatii, tehnica, rezultate.

Central pancreatectomy is a conservative resectional procedure indicated for benign and low malignant tumors located in the neck and/or body of the pancreas. We report our experience on 5 patients and some considerations about this surgical technique from medical literature.

[Pancreatic carcinoma with osteoclast-like giant cell tumor and portal vein fistula]. / Carcinom pancreatic pleomorf cu celule gigante multinucleate osteoclast-like cu fistula vasculara portala.

Osteoclast-like giant cell tumor of the pancreas (OGTP) is a rare neoplasm. We report a case of OGTP involving the head of the pancreas in a 64 year old woman with an uncommon complication--portal vein fistula. We present the diagnostic strategy and therapy. Postoperative outcome after Whipple's pancreatoduodenectomy was uneventful. The patient is still alive at 16 month after operation, without disease recurrence.

[The value of resection in pancreatic cancer: the analysis of an experience of 180 patients in 10 years]. / Valoarea rezectiei în cancerul pancreatic: analiza unei experiente de 180 de cazuri în 10 ani.

Pancreatic cancer (PC) represents one of the most severe malignant diseases, with an extremely high mortality rate (80% in the first year following diagnosis). The only potentially curative treatment is resection. This report evaluates the last 10-year experience in surgical resection for pancreatic cancer in the Center of General Surgery and Liver Transplantation from the Fundeni Clinical Institute (Bucharest--Romania), between 01.01.1995-01.05.2004. From a total of 832 patients with pancreatic cancer who were surgically treated, 180 underwent various resections (a resecability rate of 21.6%). There were 120 resections for cancer of the pancreatic head: 61 Whipple procedures, 10 pilorus preserving pancreaticoduodenectomies, 10 pancreaticoduodenectomies associated with complex resection, 17 pancreaticoduodenectomies with resection of the portal vein, 15 pancreaticoduodenectomies with extensive lymphodissection, 2 subtotal pancreatectomies and 5 total pancreatectomies; 60 standard splenopancreatectomies were performed for cancer of the pancreatic tail. The overall morbidity was 34%--61 patients (38 with cancer of the pancreatic head and 23 with pancreatic cancer of the tail), with the prevalent complication represented by pancreatic fistula. The mortality rate was 6.6%--12 patients (9 with cancer of the pancreatic head and 3 with cancer of the tail); there was a continuous decreasing trend from 9.1% between 1994-1999 to 1.6% between 2002-2004. In our Center an increasing preoccupation for pancreatic surgery, along with an improved surgical experience, resulted in a constant raise in the number of patients resected for pancreatic cancer, with a low morbidity and mortality rate.

[Surgical treatment in ulcerative rectocolitis . Analysis of a 24 years experience of 50 patients]. / Tratamentul chirurgical în rectocolita ulcerohemoragica. Analiza unei experiente de 50 de pacienti pe o perioada de 24 de ani.

Ulcerative colitis (UC) is an inflammatory bowel disease that may be cured by surgery being indicated for emergency situations resulting from complications of fulminant disease and for elective indications. We analyzed the last 24 years experience regarding 50 patients surgically treated for ulcerative colitis in the Center of General Surgery and Liver Transplantation of Fundeni Clinical Institute. The indications for surgery were: failure of medical treatment in 22 patients, acute disease with complications in 20, chronic complications in 8 cases. We used the following surgical procedures: total proctocolectomy in all 2 cases with associated rectal cancer, total colectomy with ileo-rectal anastomosis (one staged or two staged procedures) in 31, and restorative proctocolectomy in 17 cases (in all cases as a 2 or 3 staged procedure). In acute disease with complications we have performed total colectomy with terminal ileostomy, closure of the rectal stump, or exteriorization of the sigmoid stump in a mucous fistula. The gravity of acute complications does not justify the use of palliative procedures such as ileostomy, colostomy or Hartmann procedure because the mortality rate of these operations is higher than the postoperative mortality rate of total colectomy performed in emergency. Even in the elective surgery, when the patients are in a poor condition, nutritionally depleted, taking large doses of steroids or immunosuppressive drugs, we prefer the staged procedure. Total proctocolectomy is performed only in the cases of ulcerative colitis associated with rectal cancer, severe perianal disease, sphincter incontinence. Total colectomy with ileo-rectal anastomosis is indicated when the rectal stump has minimal inflammatory lesions. Restorative proctocolectomy is the surgery of choice for UC, the functional results being comparable with those of total colectomy with ileo-rectal anastomosis, but having the advantage of curing the disease. The global mortality rate was 12% (6 patients).

[Pancreaticoduodenectomy--the rutin surgery?]. / Duodenopancreatectomia cefalica--operatie de rutina?

Pancreaticoduodenectomy with or without pylorus preserving remains the only possibility for cure for the patients with malignant tumors of duodenum, periampullary and cefalopancreatic region, and distal biliary tumors; Pancreaticoduodenectomy is proceeded also for benign tumors of the head of the pancreas (chronic pancreatitis, cysts) but today the standard became preserving duodenum pancreatectomy with good functional results comparing with standard Whipple resection. The last decade had shown a dramatically decrease of the postoperative death for this kind of operations, centers with high volume have been reported a postoperative mortality rate between 1-3%. Our study is a retrospective analysis witch compare the postoperative mortality between 1 January 1990-1 October 2002. The results have shown a decrease of the postoperative mortality from 30.4% (1990-1995) to 9.8% (1995-1999) and 3.6% in the last three years (2000-2002). Also the surgeon volume of operation is closely linked with the postoperative mortality, at the first operations the postoperative mortality rate is 20-33% and after 20 pancreaticoduodenectomy the rate decrease dramatically to 2.6-5.5%. We conclude that pancreatodudenectomy today is routine operation which mortality have decreased at 5% and should be performed in high volume hospitals by surgeons with sufficient experience to minimize the postoperative death.
