BACKGROUND: The wide acceptance of laparoscopic cholecystectomy has resulted in the performance of increased numbers of cholecystectomies, hence increasing the number of patients discovered with concomitant malignancy or other pathological states. PATIENTS AND METHODS: A total of 3751 patients who underwent laparoscopic cholecystectomy between January 1995 and December 2000 were included in this study. Nine cases of coexisting malignant colonic neoplasm were discovered. All of these patients but one underwent therapeutic resection. RESULTS: The survival rate of these nine patients was the same as that of 62 consecutive colonic cancer patients who were treated in our department over the same period. The rate of postoperative complications in the study group was higher than in the control group (21 % vs. 9.5 %). The hospital stay in these patients was also greater (17 days vs. 10 days). CONCLUSION: The rate of incidental discovery of colorectal carcinomas during laparoscopic cholecystectomy in our department was 0.24 %. These patients had higher complication rates and a longer hospital stay. 相似文献

BACKGROUND: Total pancreatectomy may be warranted in patients with advanced chronic pancreatitis in whom partial resection has failed and in those with end-stage pancreatic function. A new operation, duodenum- and spleen-preserving total pancreatectomy, is described. METHODS: Nineteen consecutive patients with chronic pancreatitis who had duodenum- and spleen-preserving total pancreatectomy were studied. RESULTS: There were 15 men and four women with a median age of 40 (range 29-64) years. The aetiology was alcohol misuse in nine, hereditary pancreatitis in five and idiopathic in five patients. All patients had chronic intractable abdominal pain. Six had undergone pancreatic surgery previously and one had had multiple coeliac plexus blocks. There were ten postoperative complications in five patients, and one hospital death. The median hospital stay was 25 (range 10-84) days. There was a reduction in pain (P < 0.001) and analgesic use (P < 0.001) after surgery, and weight gain was noted at 12 and 24 months (P < 0.001). Nine patients required readmission to hospital, four because of surgical complications: adhesional obstruction in one, biliary stricture in two and duodenal obstruction in one. In the other five patients (four of whom had long-standing pre-existing diabetes mellitus) readmission was for better control of pain (three patients), diabetes mellitus (two), and diabetes-associated diarrhoea (two) or gastropathy (one). CONCLUSION: Duodenum- and spleen-preserving total pancreatectomy has a role in selected patients with medically intractable pain from chronic pancreatitis. 相似文献

During laparoscopic cholecystectomy (LC) there is possibility of discovering concomitant occult intra-abdominal pathology and the surgeon must be prepared to undertake the appropriate procedure. We evaluated the incidence of latent perforated duodenal ulcer in 5539 patients who underwent LC for gallstone disease at our unit between November 1991 and November 2001. Seven (0.13 %) cases of perforated duodenal ulcer were discovered. Following the diagnosis of the perforation, laparoscopic suturing and omental patch repair was carried out in four patients, open repair with selective vagotomy and pyloroplasty in two patients and an open suture and omental patch repair in one patient. In all cases the cholesystectomy was completed successfully. 相似文献

BACKGROUND/AIMS: As laparoscopic colectomy finds its place in the surgical armamentarium, the literature concerning the safety, efficacy, and oncological rational for treatment of colonic cancer is also enriched. A review and critical appraisal of the literature on this subject was the aim of this paper. METHODS: A systematic research and a hand search were conducted to gain access to all controlled studies involving laparoscopic colectomy using the Medline, Embase, HealthSTAR, Cumulative Index for Nursing and Allied Health Literature, CancerLit data bases and the Cochrane Central Register of Controlled Trials for the years 1991-2006. RESULTS: Over 40 controlled randomized trials and ten systematic reviews and/or meta-analyses were found. Several of the completed controlled randomized trials have published either short- or long-term results; only partial and short-term results are available in rectal cancer. The principal conclusions are that the laparoscopic approach affords better short-term outcomes including surgical site morbidity, but with increased operative times and direct costs. Among the proven long-term outcomes, cancer recurrence and survival do not seem to be worse. Whether conversion, a source of increased operative time and costs, is responsible for poorer outcomes or whether specific settings associated with poorer outcomes are among the causes of conversion remains to be shown. However, there are still concerns as regards specific laparoscopic-related complications. CONCLUSION: There seems to no real safety problems in performing laparoscopic colectomy for cancer; improvement in operative times, conversion rates, and complications should make laparoscopy the best cost-effective approach to colectomy. 相似文献

Background
The present study is a meta-analysis of English articles comparing one-stage [laparoscopic common bile duct exploration or intra-operative endoscopic retrograde cholangiopancreatography (ERCP)] vs. two-stage (laparoscopic cholecystectomy preceded or followed by ERCP) management of common bile duct stones.Methods
MEDLINE/PubMed and Science Citation Index databases (1990–2011) were searched for randomized, controlled trials that met the inclusion criteria for data extraction. Outcomes were calculated as odds ratios (ORs) with 95% confidence intervals (CIs) using RevMan 5.1.Results
Nine trials with 933 patients were studied. No significant differences was observed between the two groups with regard to bile duct clearance (OR, 0.89; 95% CI, 0.65–1.21), mortality (OR, 1.2; 95% CI, 0.32–4.52), total morbidity (OR, 0.75; 95% CI, 0.53–1.06), major morbidity (OR, 0.95; 95% CI, 0.60–1.52) and the need for additional procedures (OR, 1.58; 95% CI, 0.76–3.30).Conclusions
Outcomes after one-stage laparoscopic/endoscopic management of bile duct stones are no different to the outcomes after two-stage management. 相似文献17.
Chronic kidney disease is characterized by progressive accumulation of extracellular matrix and scarring, leading to the loss of kidney function. Excess deposition of the collagen family of proteins is the hallmark of kidney fibrosis. In this review, we survey the collagens that are associated with renal disease and we highlight the use of a transgenic approach to identify cis-acting sequences in the collagen type I promoter which are capable of directing collagen type I expression specifically in the kidney. Ultimately it may be possible to use this approach to halt the accumulation of collagen selectively in this organ. 相似文献

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Activating mutations in tyrosine kinase receptors KIT or platelet-derived growth factor receptor alpha (PDGFRA) are the main mechanisms causing the disease. Patients generally present with non-specific symptoms, while a number of tumors are discovered incidentally and may be metastatic at the time of diagnosis. Aggressive GISTs have a defined pattern of metastasis to the liver or throughout the abdomen, or both. Though GISTs rarely present systemic or isolated paraneoplastic reactions, a few cases have been reported in the literature. We present the case of a 54-year-old patient with metastatic GIST at diagnosis and the emergence of paraneoplastic manifestations during follow-up. 相似文献
