Rawicz-Pruszyński K, Erodotou M, Pelc Z, Sędłak K, Polkowski W, Pawlik TM, Wijnhoven BP. Techniques of staging laparoscopy and peritoneal fluid assessment in gastric cancer: a systematic review. Int J Surg 2023; 109:3578-3589. [PMID: 37581636 PMCID: PMC10651295 DOI: 10.1097/js9.0000000000000632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 07/13/2023] [Indexed: 08/16/2023]
Abstract
BACKGROUND Staging laparoscopy for gastric cancer is recommended to assess the tumor's locoregional extension and exclude peritoneal disease. As there is no consensus on optimizing the procedure's diagnostic accuracy, we aimed to systematically review the literature on operative techniques, followed by peritoneal lavage fluid assessment in gastric cancer patients. Specifically, we sought to indicate the most common characteristics of the procedure and cytological evaluation. METHODS This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol for this systematic review was registered on PROSPERO database (CRD: 42022306746). On September 2022, a search was carried out using Embase, Medline ALL, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection. RESULTS The search identified 1632 studies on staging laparoscopy and 2190 studies on peritoneal fluid assessment. Some 212 studies were included. Open Hasson was the method of choice in accessing the peritoneal cavity in 65% of the studies, followed by establishing a pneumoperitoneum at 10-12 mmHg in 52% of reports. Most frequently, the patient was positioned supine (70%), while a 30° scope and three ports were used to assess the peritoneal cavity clockwise (72%, 77%, and 85%, respectively). Right and left upper abdomen quadrants were the predominant area of laparoscopic exploration (both 65%), followed by the primary tumor region (54%), liver and pelvis (both 30%), and small bowel and spleen (19% and 17%, respectively). Regions of peritoneal lavage and aspiration were limited to the pelvis (50%), followed by right and left upper abdomen quadrants (37.5% and 50%, respectively). No studies compared different methods of operative techniques or analysis of ascites/fluid. CONCLUSIONS This study indicates a high heterogeneity in the technique of staging laparoscopy and peritoneal fluid assessment in gastric cancer patients. Further research and initiatives to reach a consensus on the standardization of the procedure are warranted.

Diffusely infiltrative squamous cell carcinoma of the esophagus resembling scirrhous gastric cancer: a case report. Ann Med Surg (Lond) 2023; 85:266-270. [PMID: 36845766 PMCID: PMC9949778 DOI: 10.1097/ms9.0000000000000187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Accepted: 12/24/2022] [Indexed: 02/28/2023] Open
Abstract
Diffusely infiltrative squamous cell carcinoma of the esophagus is rare and difficult to diagnose. Case presentation The patient was a 75-year-old woman whose chief complaints were dysphagia and upper abdominal pain. Esophagogastroduodenoscopy and biopsy revealed squamous cell carcinoma at the abdominal esophagus. After neoadjuvant chemotherapy, esophagogastroduodenoscopy showed diffuse thickening and poor distensibility of the stomach wall. We suspected scirrhous gastric cancer and performed multiple biopsies, which revealed no evidence of malignancy. We then performed staging laparoscopy. There were no apparent changes in the serous membrane of the stomach, but peritoneal lavage cytology revealed squamous cell carcinoma. Thus, we made a diagnosis of squamous cell carcinoma of the esophagus with diffuse invasion of the stomach. Intraoperative pathological diagnosis revealed that there was greater diffuse submucosal invasion of the oral esophagus than we expected, and we had to resect the esophagus at the level of the middle thoracic esophagus. Despite multidisciplinary treatment (surgery, chemotherapy, and radiotherapy), the patient died 20 months after the initial diagnosis. Clinical discussion In this case, although biopsy did not lead to a diagnosis, peritoneal lavage cytology led to the correct diagnosis. Moreover, it was impossible to preoperatively predict the exact extent of the expansion because of diffuse submucosal invasion. Conclusion When diffusely infiltrative squamous cell carcinoma of the esophagus is suspected, peritoneal lavage cytology may be useful for confirming the diagnosis; however, it should be assumed that accurate preoperative evaluation of the range of diffusely infiltrative squamous cell carcinoma is difficult.

Abstract
OBJECTIVES The aims of this review were to determine whether positive peritoneal lavage cytology (CY+) precludes radical resection in pancreatic cancer and to propose prospections for future studies. METHODS MEDLINE, Embase, and Cochrane Central were searched for related articles. Dichotomous variables and survival outcomes were analyzed with the estimation of odds ratio and hazards ratio (HR), respectively. RESULTS A total of 4905 patients were included, of which 7.8% were CY+. Positive peritoneal lavage cytology was correlated with poor overall survival (univariate survival analysis [HR, 2.35; P < 0.00001]; multivariate analysis [HR, 1.62; P < 0.00001]), poor recurrence-free survival (univariate survival analysis [HR, 2.50; P < 0.00001]; multivariate analysis [HR, 1.84; P < 0.00001]), and higher initial peritoneal recurrence rate (odds ratio, 5.49; P < 0.00001). CONCLUSIONS Although CY+ predicts poor prognosis and a higher risk of peritoneal metastasis after curative resection, it is not sufficient to preclude curative resection based on the current evidence, and high-quality trials should be conducted to assess the prognostic impact of operation among resectable CY+ patients. In addition, more sensitive and accurate methods to detect peritoneal exfoliated tumor cells and more effective comprehensive treatment for resectable CY+ pancreatic cancer patients are clearly warranted.

Rare Abdominal Wall Metastasis following Curative Resection of Gastric Cancer: What Can Be Learned from the Use of Percutaneous Catheters? Case Rep Oncol Med 2020; 2020:3738798. [PMID: 32509367 PMCID: PMC7244962 DOI: 10.1155/2020/3738798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 04/21/2020] [Accepted: 04/23/2020] [Indexed: 11/17/2022] Open
Abstract
In cancer care, tissue seeding after curative resections is a known potential complication, despite precautions taken during surgical treatment. We present an uncommon case of an abdominal wall metastasis along the tract of a surgical drain following gastrectomy for gastric adenocarcinoma. To our knowledge, this is the first case of such an occurrence in the setting of a negative staging peritoneal lavage. Aside from the rarity of such a recurrence, this instance highlights an opportunity to reevaluate best practices with regard to the extent of coverage of postoperative salvage radiotherapy. The oncologic patient provides many challenges and may require multiple catheters for drainage and at times infusion of nutrition or therapeutic agents. These foreign bodies should be scrutinized both clinically and radiographically, as they may create vulnerabilities in keeping malignant diseases contained and controlled. We provide a review of the literature with reasonable treatment options for the benefit of future patients.

Abstract
Introduction: Biomarkers are biological molecules entirely or partially participating in cancerous processes that function as measurable indicators of abnormal changes in the human body microenvironment. Aiming to provide an overview of associations between prognostic biomarkers and gastric cancer (GC), we performed this umbrella review analyzing currently available meta-analyses and grading the evidence depending on the credibility of their associations. Methods: A systematic literature search was conducted by two independent investigators of the PubMed, Embase, Web of Science, and Cochrane Databases to identify meta-analyses investigating associations between prognostic biomarkers and GC. The strength of evidence for prognostic biomarkers for GC were categorized into four grades: strong, highly suggestive, suggestive, and weak. Results: Among 120 associations between prognostic biomarkers and GC survival outcomes, only one association, namely the association between platelet count and GC OS, was supported by strong evidence. Associations between FITC, CEA, NLR, foxp3+ Treg lymphocytes (both 1- and 3-year OS), CA 19-9, or VEGF and GC OS were supported by highly suggestive evidence. Four associations were considered suggestive and the remaining 108 associations were supported by weak or not suggestive evidence. Discussion: The association between platelet count and GC OS was supported by strong evidence. Associations between FITC, CEA, NLR, foxp3+ Treg lymphocytes (both 1- and 3-year OS), CA 19-9, or VEGF and GC OS were supported by highly suggestive evidence, however, the results should be interpreted cautiously due to inadequate methodological quality as deemed by AMSTAR 2.0.

Abstract
BACKGROUND Positive peritoneal cytology is classified as M1 disease in gastric and pancreatic cancer. While peritoneal cytology is typically obtained by laparoscopic peritoneal lavage, this study sought to examine the feasibility and safety of performing this percutaneously, with monitored anesthesia care and in combination with other diagnostic procedures to condense and expedite the staging process. METHODS Patients with gastric or pancreatic cancer scheduled for laparoscopy with peritoneal lavage were prospectively enrolled to undergo intraoperative percutaneous peritoneal lavage prior to laparoscopic peritoneal lavage. Saline was infused through a percutaneously-inserted catheter and fluid was collected for peritoneal cytology. Three-quadrant washings collected during laparoscopy were also sent for peritoneal cytology. The primary outcome was to evaluate the sensitivity and specificity of percutaneous peritoneal lavage for detecting positive peritoneal cytology compared with the gold standard of laparoscopic peritoneal lavage, while the secondary outcome was to determine safety. RESULTS Percutaneous peritoneal lavage was successfully performed in 70 of 76 patients (92%). Ten of 48 gastric cancer patients (21%) and three of 22 pancreatic cancer patients (14%) had positive percutaneous and laparoscopic peritoneal cytology. Two additional gastric cancer patients had positive laparoscopic peritoneal cytology only. Sensitivity and specificity of percutaneous peritoneal lavage compared with laparoscopic peritoneal lavage were 87% and 100%, respectively. No complications occurred with percutaneous peritoneal lavage. CONCLUSIONS Percutaneous peritoneal lavage is a safe and effective minimally invasive alternative to laparoscopic peritoneal lavage for the diagnosis of metastatic gastric and pancreatic cancer. It is possible this can be utilized in an outpatient setting, such as during endoscopy, to allow for earlier diagnosis of M1 disease and decreased time to appropriate treatment.

Abstract
Treatment options for patients with gastric cancer (GC) are based on tumor staging and resectability. Although only surgery provides improved survival, resection is contraindicated and should be avoided in the presence of intra-abdominal disease stage M1 (liver, peritoneal, or non-local lymph node metastases). Thus, a detailed and precise evaluation is imperative for optimal treatment. Staging laparoscopy (SL) constitutes a major tool in the accurate diagnosis of several types of cancers, including GC. SL presents several critical advantages: it can diagnose intra-abdominal disease; serve as a complement to other imaging studies; allow for biopsies; facilitate intraoperative ultrasound evaluations; allow for sampling of peritoneal fluid for cytological examination; and serve as an option for the administration of intraperitoneal chemotherapy. Although considered and advocated as a very useful asset in the pre-treatment cancer-staging arsenal, the wider application of SL has been long debated. The purpose of our study was to evaluate the contribution of laparoscopy to GC staging.

Abstract
BACKGROUND Surgical resection is the only potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Laparoscopy can detect metastases not visualised on CT scanning, enabling better assessment of the spread of cancer (staging of cancer). This is an update to a previous Cochrane Review published in 2013 evaluating the role of diagnostic laparoscopy in assessing the resectability with curative intent in people with pancreatic and periampullary cancer. OBJECTIVES To determine the diagnostic accuracy of diagnostic laparoscopy performed as an add-on test to CT scanning in the assessment of curative resectability in pancreatic and periampullary cancer. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, EMBASE via OvidSP (from inception to 15 May 2016), and Science Citation Index Expanded (from 1980 to 15 May 2016). SELECTION CRITERIA We included diagnostic accuracy studies of diagnostic laparoscopy in people with potentially resectable pancreatic and periampullary cancer on CT scan, where confirmation of liver or peritoneal involvement was by histopathological examination of suspicious (liver or peritoneal) lesions obtained at diagnostic laparoscopy or laparotomy. We accepted any criteria of resectability used in the studies. We included studies irrespective of language, publication status, or study design (prospective or retrospective). We excluded case-control studies. DATA COLLECTION AND ANALYSIS Two review authors independently performed data extraction and quality assessment using the QUADAS-2 tool. The specificity of diagnostic laparoscopy in all studies was 1 because there were no false positives since laparoscopy and the reference standard are one and the same if histological examination after diagnostic laparoscopy is positive. The sensitivities were therefore meta-analysed using a univariate random-effects logistic regression model. The probability of unresectability in people who had a negative laparoscopy (post-test probability for people with a negative test result) was calculated using the median probability of unresectability (pre-test probability) from the included studies, and the negative likelihood ratio derived from the model (specificity of 1 assumed). The difference between the pre-test and post-test probabilities gave the overall added value of diagnostic laparoscopy compared to the standard practice of CT scan staging alone. MAIN RESULTS We included 16 studies with a total of 1146 participants in the meta-analysis. Only one study including 52 participants had a low risk of bias and low applicability concern in the patient selection domain. The median pre-test probability of unresectable disease after CT scanning across studies was 41.4% (that is 41 out of 100 participants who had resectable cancer after CT scan were found to have unresectable disease on laparotomy). The summary sensitivity of diagnostic laparoscopy was 64.4% (95% confidence interval (CI) 50.1% to 76.6%). Assuming a pre-test probability of 41.4%, the post-test probability of unresectable disease for participants with a negative test result was 0.20 (95% CI 0.15 to 0.27). This indicates that if a person is said to have resectable disease after diagnostic laparoscopy and CT scan, there is a 20% probability that their cancer will be unresectable compared to a 41% probability for those receiving CT alone.A subgroup analysis of people with pancreatic cancer gave a summary sensitivity of 67.9% (95% CI 41.1% to 86.5%). The post-test probability of unresectable disease after being considered resectable on both CT and diagnostic laparoscopy was 18% compared to 40.0% for those receiving CT alone. AUTHORS' CONCLUSIONS Diagnostic laparoscopy may decrease the rate of unnecessary laparotomy in people with pancreatic and periampullary cancer found to have resectable disease on CT scan. On average, using diagnostic laparoscopy with biopsy and histopathological confirmation of suspicious lesions prior to laparotomy would avoid 21 unnecessary laparotomies in 100 people in whom resection of cancer with curative intent is planned.

Abstract
PURPOSE Despite continuously improving therapies, gastric cancer still shows poor survival in locally advanced stages with local recurrence rates of up to 50% and peritoneal recurrence rates of 17% after curative surgery. We performed a systematic review with meta-analyses to clarify whether positive intraperitoneal cytology (IPC) indicates a high risk of disease recurrence and poor overall survival in gastric cancer. METHODS Multiple databases were searched in December 2014 to identify studies on the prognostic significance of positive intraperitoneal cytology in gastric cancer, including: Medline, Biosis, Science Citation Index, Embase, CCMed and publisher databases. Hazard ratios (HR) and associated 95% confidence intervals (CI) were extracted from the identified studies. A meta-analysis was performed using a random-effects model on overall survival, disease-free survival and peritoneal recurrence free survival. RESULTS A total of 64 studies with a cumulative sample size of 12,883 patients were included. Cytology, quantitative real time polymerase chain reaction (PCR) or both were performed in 35; 21 and 8 studies, respectively. Meta analyses revealed free intraperitoneal tumor cells (FITC) to be associated with poor overall survival in univariate (HR 3.27; 95% CI 2.82 - 3.78]) and multivariate (HR 2.45; 95% CI 2.04 - 2.94) analysis and poor peritoneal recurrence free survival in univariate (4.15; 95% CI 3.10 - 5.57) and multivariate (3.09; 95% CI 2.02 - 4.71) analysis. Subgroup analysis showed this effect to be independent of the detection method, Western or Asian origin or the time of publication. CONCLUSIONS FITC oder positive peritoneal cytology is associated with poor survival and increased peritoneal recurrence in gastric cancer.

Abstract
BACKGROUND Surgical resection is the only potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Laparoscopy can detect metastases not visualised on CT scanning, enabling better assessment of the spread of cancer (staging of cancer). There has been no systematic review or meta-analysis assessing the role of diagnostic laparoscopy in assessing the resectability with curative intent in patients with pancreatic and periampullary cancer. OBJECTIVES To determine the diagnostic accuracy of diagnostic laparoscopy performed as an add-on test to CT scanning in the assessment of curative resectability in pancreatic and periampullary cancer. SEARCH METHODS We searched the Cochrane Register of Diagnostic Test Accuracy Studies, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, EMBASE via OvidSP (from inception to 13 September 2012), and Science Citation Index Expanded (from 1980 to 13 September 2012). SELECTION CRITERIA We included diagnostic accuracy studies of diagnostic laparoscopy in patients with potentially resectable pancreatic and periampullary cancer on CT scan, where confirmation of liver or peritoneal involvement was by histopathological examination of suspicious (liver or peritoneal) lesions obtained at diagnostic laparoscopy or laparotomy. We accepted any criteria of resectability used in the studies. We included studies irrespective of language, publication status, or study design (prospective or retrospective). We excluded case-control studies. DATA COLLECTION AND ANALYSIS Two authors independently performed data extraction and quality assessment using the QUADAS-2 tool. The specificity of diagnostic laparoscopy in all studies was 1 because there were no false positives since laparoscopy and the reference standard are one and the same if histological examination after diagnostic laparoscopy is positive. Therefore, the sensitivities were meta-analysed using a univariate random-effects logistic regression model. The probability of unresectability in patients who had a negative laparoscopy (post-test probability for patients with a negative test result) was calculated using the median probability of unresectability (pre-test probability) from the included studies and the negative likelihood ratio derived from the model (specificity of 1 assumed). The difference between the pre-test and post-test probabilities gave the overall added value of diagnostic laparoscopy compared to the standard practice of CT scan staging alone. MAIN RESULTS Fifteen studies with a total of 1015 patients were included in the meta-analysis. Only one study including 52 patients had a low risk of bias and low applicability concern in the patient selection domain. The median pre-test probability of unresectable disease after CT scanning across studies was 40.3% (that is 40 out of 100 patients who had resectable cancer after CT scan were found to have unresectable disease on laparotomy). The summary sensitivity of diagnostic laparoscopy was 68.7% (95% CI 54.3% to 80.2%). Assuming a pre-test probability of 40.3%, the post-test probability of unresectable disease for patients with a negative test result was 0.17 (95% CI 0.12 to 0.24). This indicates that if a patient is said to have resectable disease after diagnostic laparoscopy and CT scan, there is a 17% probability that their cancer will be unresectable compared to a 40% probability for those receiving CT alone.A subgroup analysis of patients with pancreatic cancer gave a summary sensitivity of 67.9% (95% CI 41.1% to 86.5%). The post-test probability of unresectable disease after being considered resectable on both CT and diagnostic laparoscopy was 18% compared to 40% for those receiving CT alone. AUTHORS' CONCLUSIONS Diagnostic laparoscopy may decrease the rate of unnecessary laparotomy in patients with pancreatic and periampullary cancer found to have resectable disease on CT scan. On average, using diagnostic laparoscopy with biopsy and histopathological confirmation of suspicious lesions prior to laparotomy would avoid 23 unnecessary laparotomies in 100 patients in whom resection of cancer with curative intent is planned.

Abstract
INTRODUCTION The Siewert classification has been used to plan treatment for tumours of the gastro-oesophageal junction since its proposal in the 1980s. The purpose of this study was to assess its continued relevance by evaluating whether there were differences in the biology and clinical characteristics of adenocarcinomas by Siewert type, in a contemporary cohort of patients, in whom the majority had received neoadjuvant chemotherapy. METHODS A prospective database was reviewed for all patients who underwent resection from 2005 to 2011 and analysed with regard to Siewert classification determined from the pathological specimen, treatment and clinicopathological outcomes. RESULTS Two hundred and sixteen patients underwent oesophagogastric resection: 133 for type I, 51 for type II and 33 for type III tumours. 135 Patients (62.5%) received neoadjuvant chemotherapy with no difference between groups. There were no significant differences in age, sex, pT stage, pN stage, pM stage, ASA, or inpatient complications between patients with adenocarcinoma based on their Siewert classification. There was a significant increase in maximum tumour diameter (P = 0.023), perineural invasion (P = 0.021) and vascular invasion (P = 0.020), associated with more distal tumours (Type III > Type II > Type I). Median overall survival was significantly shorter for more distal tumours (Type I: 4.96 years vs. Type II: 3.3 years vs. Type III: 2.64 years; P = 0.04). The surgical approach did not influence survival. CONCLUSION In the era of multi-modal treatment pathological Siewert tumour type is of prognostic value, as patients with Type III disease are likely to have larger and more aggressive tumours that lead to worse outcomes.

Abstract
AIM: To investigate the value of staging laparoscopy with laparoscopic ultrasound (LUS) and peritoneal lavage cytology in patients with newly-diagnosed gastric tumours in our department.
METHODS: Retrospective review of prospectively-collected data was conducted in all patients with newly-diagnosed gastric tumours on oesophagogastroduodenoscopy between December 2003 and July 2008. All the patients had a pre-treatment histological diagnosis and were discussed at the hospital multidisciplinary tumour board meeting for their definitive management. Computed tomography scan was performed in all patients as a part of standard preoperative staging work up. Staging laparoscopy was subsequently performed in selected patients and staging by both modalities was compared.
RESULTS: Twenty seven patients were included. Majority of patients had cardio-oesophageal junction adenocarcinoma. Thirteen patients (48%) were upstaged following staging laparoscopy and one patient was downstaged (3.7%). None of the patients had procedure-related complications. None of the patients with metastasis detected at laparoscopy underwent laparotomy. Gastrectomy after staging laparoscopy was performed in 13 patients (9 R0 resections, 3 R1 resections and 1 R2 resection). Only one patient did not have gastrectomy at laparotomy because of extensive local invasion. Three patients were subjected to neoadjuvant therapy following laparoscopy but only one patient subsequently underwent gastrectomy.
CONCLUSION: In this small series reflecting our institutional experience, staging laparoscopy appears to be safe and more accurate in detecting peritoneal and omental metastases as compared to conventional imaging. Peritoneal cytology provided additional prognostic information although there appeared to be a high false negative rate.

Abstract
Even after extensive preoperative assessment, staging laparoscopy may allow avoidance of non-therapeutic laparotomy in patients with radiographically occult metastatic or locally unresectable disease. Staging laparoscopy is associated with decreased postoperative pain, a shorter hospital stay and a higher likelihood of receiving systemic therapy compared to laparotomy but its yield has decreased with improvements in imaging techniques. Current uses of staging laparoscopy include the following: (1) In the staging of pancreatic adenocarcinoma, laparoscopic staging allows for the identification of sub-radiographic metastatic disease in locally advanced cancer in approximately 30% of patients and, in radiographically resectable cancer, may identify metastatic disease in 10%-15% of cases; (2) In colorectal liver metastases, selective use of laparoscopic staging in patients with a clinical risk score of over 2 identifies unresectable disease in approximately 20% of patients; (3) In hepatocellular carcinoma, laparoscopic staging could be selectively used in high-risk patients such as those with clinically apparent liver cirrhosis and in patients with major vascular invasion or bilobar tumors; and (4) In biliary tract malignancy, staging laparoscopy may be used in all patients with potentially resectable primary gallbladder cancer and in selected patients with T2/T3 hilar cholangiocarcinoma. Because of the decreasing yield of SL secondary to improvements in imaging techniques, staging laparoscopy should be used selectively for patients with pancreatic and hepatobiliary malignancy to avoid unnecessary non-therapeutic laparotomy and to improve resource utilization. Each individual surgeon should apply his or her threshold as to whether staging laparoscopy is indicated according to the quality of preoperative imaging studies and the availability of resources at their own institution.

Abstract
Early detection and accurate staging of gastrointestinal (GI) cancers are difficult. The aim of this study was to evaluate whether telomerase activity (TA) in exfoliated/disseminated epithelial cells could be used as a reliable marker for GI cancers. TA was evaluated with the real-time RTQ-TRAP in immunomagnetically sorted peritoneal epithelial cells from 60 patients undergoing surgical treatment. Thirty-two patients were clinically diagnosed with a variety of GI cancers: 1 had premalignant disease, 2 had history of GI cancers, and 25 patients were clinically negative for cancer. Here we report that all types and all cases of gastrointestinal cancers were telomerase positive, thereby demonstrating 100% sensitivity for cancer. Eighteen of 25 nonmalignant cases had undetectable levels of TA, 2 had low, and 5 of 25 expressed high TA levels. Because normal epithelial cells usually have low TA and a lesser tendency to exfoliate compared with cancer cells, it is of great importance to have close follow-up for these patients to exclude possible malignant disease. We conclude that RTQ-TRAP assessment of TA in immunomagnetically sorted peritoneal epithelial cells has 100% sensitivity and 100% negative predictive value for GI cancers, and therefore, can be considered as a valuable tool and useful addition to current standard diagnostic methods. Clinical significance of unusually high telomerase activity in some clinically negative for cancer cases requires further study.

Abstract
BACKGROUND More accurate preoperative staging is necessary to determine the treatment strategy for locally advanced gastric cancer. Laparoscopy has been suggested as an appropriate staging modality. The aim of this study was to clarify the role of staging laparoscopy in patients with locally advanced gastric cancer. METHODS One hundred patients with primary gastric adenocarcinoma underwent laparoscopy with peritoneal lavage cytology. The disease stages determined were compared with those obtained by conventional methods. RESULTS The disease stages were corrected after laparoscopy for 47 of the 100 patients (47%), with downstaging in 3 (3.0%) and upstaging in 44 (44%). Peritoneal deposits were found in 7 patients with peritoneal dissemination diagnosed by conventional examination. An unsuspected peritoneal deposit was found in 21 of 93 patients (22.6%), and unsuspected free cancer cells without deposits were found in 27 of 93 patients (29.0%). Gastrectomy after staging laparoscopy was performed in 39 patients. Laparoscopy showed no peritoneal deposits in any of these patients. Free cancer cells were found in 9 patients (23.1%), but 4 of these had peritoneal deposits at operation. R0 resection was performed in 34 of the 39 patients (87.2%). Neoadjuvant chemotherapy after staging laparoscopy was performed in 35 patients. All 35 patients underwent gastrectomy, which resulted in 27 R0 and 8 R2 resections. Of 18 patients with positive cytology at laparoscopy, 11 had no free cancer cells at operation. Neoadjuvant chemotherapy induced downstaging of the disease in 11 of the 18 patients with positive cytology (61.1%). Of 26 patients with massive peritoneal deposits, 4 underwent palliative resection because of pyloric stenosis. Twenty-two patients (22.0%) were able to avoid unnecessary laparotomy because of the staging laparoscopy. CONCLUSION Staging laparoscopy with peritoneal lavage cytology is a safe, effective tool in patients with locally advanced gastric cancer, especially in patients receiving neoadjuvant chemotherapy.

Abstract
In the absence of metastatic disease patients with localized or locally advanced pancreatic cancer can benefit from surgical resection or chemoradiation. Despite the advances of imaging technology, however, noninvasive staging modalities are still inaccurate in identifying small volume metastatic disease leading potentially to inappropriate treatment and avoidable morbidity in a subgroup of patients. Staging laparoscopy may identify those patients with unsuspected metastatic disease on preoperative imaging and prevent unnecessary laparotomy or chemoradiation. A controversy exists, however, as to whether the procedure should be used routinely or selectively in pancreatic cancer patients with no evidence of metastasis on noninvasive staging. This review aims to assess the current role of staging laparoscopy by examining its diagnostic accuracy and ability to prevent unnecessary treatment as well as its morbidity, oncologic effect and cost-effectiveness. The available literature will be evaluated critically, its limitations identified and exisiting controversies addressed.

Abstract
Tumor progression after curative resection of gastrointestinal cancer is probably caused by disseminated tumor cells that can be detected in different body compartments, e.g. the peritoneum. The clinical importance and prognostic significance of gross peritoneal metastasis is well known whereas the prognostic relevance of disseminated tumor cells in the peritoneum of patients with gastrointestinal cancer is still unclear. Disseminated tumor cells in the peritoneal cavity are generally detected by cytology, immunohistochemistry or polymerase chain reaction-based molecular methods. A consensus on the most adequate detection method has not yet been found making the comparison of different data difficult. The prognostic relevance of tumor cell dissemination has, at least in part, been shown for gastric, pancreatic and colon cancer, and the prognostic data regarding gastric cancer are most convincing. Peritoneal "micrometastases" are obviously not equivalent to distant metastases as the evidence for their prognostic significance is clearly less than that for gross peritoneal metastases. This article gives a critical review of the detection and prognostic significance of disseminated tumor cells in the peritoneum of patients with gastrointestinal cancer.

Abstract
In this study, we evaluated and compared the value of spiral computed tomography, transabdominal ultrasonography, laparoscopy, and laparoscopic ultrasonography in staging gastric cancer in 37 patients; there was a special interest in the additional information provided by laparoscopic ultrasonography. Although laparoscopy was unreliable or hindered by adhesions in 11% of the patients, the benefit of laparoscopy for staging was evident especially for the detection of peritoneal carcinomatosis that was missed by the other diagnostic modalities. Laparoscopic ultrasonography did not change the stage of the disease nor the decision whether to proceed with laparotomy for any of the patients. The decision whether to proceed with laparotomy was correctly predicted in 95% of the cases.

Abstract
The role of diagnostic laparoscopy in patients with periampullary and pancreatic malignancies is controversial. A retrospective review was performed including all patients (n = 188) with a periampullary or pancreatic malignancy who underwent both CT and laparotomy at our institution between January 1997 and December 1999. The overall resectability rate for all periampullary cancers was 67.3% (115 of 171 patients). This compared favorably with the resectability rate for cancers of the pancreatic body and tail (3 of 17 patients, 17.6%; P < 0.01 vs. periampullary cancers). Fifty percent of patients with periampullary cancers were unresectable because of metastatic disease, whereas metastatic disease precluded resection in 64.3% of patients with cancers of the pancreatic body and tail. After patients undergoing operative palliation were eliminated, a nontherapeutic laparotomy would have been precluded by the use of diagnostic laparoscopy in only 2.3% of patients with periampullary cancers (4 of 171 patients). In contrast, 6 (35.3%) of 17 patients with cancers of the pancreatic body and tail underwent a nontherapeutic laparotomy (P < 0.01 vs. periampullary cancers). One hundred fifty-eight (84%) of the 188 CT reports reviewed could be definitively categorized as either "likely to be resectable" or "likely to be unresectable." The remaining 16% were equivocal. Of the 107 patients categorized as likely to be resectable, 89 were actually resected (83.2%). In contrast, only 10 of the 51 patients categorized as likely to be unresectable could be resected (19.6%).

Abstract
OBJECTIVE To determine the relative benefit of staging laparoscopy in peripancreatic and biliary malignancies. SUMMARY BACKGROUND DATA Staging laparoscopy has been used in a variety of peripancreatic and biliary malignancies. The utility of the technique in subsets of these types of cancer has not been systematically compared. METHODS One hundred fifty-seven patients underwent laparoscopy after conventional tumor staging; 89 were also staged with laparoscopic ultrasonography. Diagnostic categories were cancer of the pancreatic head and uncinate process, cancer of the body and tail of pancreas, cancer of the extrahepatic bile duct, cancer of the gallbladder, and cancer of the ampulla of Vater/duodenum. RESULTS In patients with cancer of the head of the pancreas, metastatic disease or vascular invasion was discovered frequently by laparoscopy (31%), whereas in ampullary/duodenal cancer it was never found. The laparoscopic findings in cancer of the head of the pancreas had an important influence on treatment decisions, whereas in cancer of the ampulla/duodenum, laparoscopy had no effect on clinical decisions. Laparoscopy also substantially influenced the treatment of gallbladder cancer; in other tumor types, results were intermediate. Laparoscopic ultrasonography was valuable in cancer of the head of the pancreas. CONCLUSIONS The utility of staging laparoscopy depends on diagnosis. It is recommended for continued use in pancreatic head and gallbladder cancers but not in ampullary malignancies.

Abstract
BACKGROUND AND OBJECTIVES Borrmann type IV gastric carcinoma (B-4) remains a disease with poor prognosis despite an aggressive surgical approach. Cytology examination of the peritoneal washes is an established prognostic factor for gastric carcinoma in general, and may be useful for identifying adequate treatment strategy for B-4. METHODS Pathologic data from 70 patients with B-4 who underwent laparotomy and peritoneal washing cytology during the recent 6 years were retrieved from a prospective computer database and reviewed. Prognostic significance of the cytology examination along with other known clinicopathologic variables was evaluated by univariate and multivariate analyses. RESULTS Long-term survivors were observed only among the patients who were treated with curative R0 resection. Prognosis of the patients with positive cytology and no other residual disease (R1) was extremely poor and was equivalent to that of the patients undergoing noncurative R2 resection. No difference in survival, either, was observed between the patients treated by R2 resection and those who did not undergo resection. Multivariate analysis identified cytology examination as an independent prognostic factor. CONCLUSIONS Peritoneal washing cytology plays an important role in staging B4. Positive cytology findings as well as other evidence of disseminated disease may indicate that gastrectomy should be avoided.

Abstract
BACKGROUND The benefit of preoperative biliary drainage in jaundiced patients undergoing pancreaticoduodenectomy for a suspected malignancy of the periampullary region is still under debate. This study evaluated preoperative biliary drainage in relation to postoperative outcomes. STUDY DESIGN At the Academic Medical Center, Amsterdam, the Netherlands, a cohort of 311 patients undergoing pancreaticoduodenectomy from June 1992 up to and including December 1999 was studied. Of this cohort 21 patients with external or surgical biliary drainage were excluded and 232 patients who had received preoperative internal biliary drainage were divided into three groups corresponding with severity of jaundice according to preoperative plasma bilirubin levels: < 40 microM (n = 177), 40 to 100 microM (n = 32), and > 100 microM (n = 23) were designated as groups 1, 2, and 3, respectively. These groups were compared with patients who underwent immediate surgery (n = 58) without preoperative drainage. RESULTS The median number of stent (re)placements was 2 (range 1 to 6) with a median drainage duration of 41 days (range 2 to 182 days) and a stent dysfunction rate of 33%. Although patients in group 1 were better drained than patients in groups 2 and 3 (median reduction of bilirubin levels 82%, 57%, and 37%, respectively, p < 0.01), there was no difference in overall morbidity among the drained groups (50%, 50%, and 52%, respectively). There was no significant difference in overall morbidity between patients with and without preoperative biliary drainage (50% and 55%, respectively). CONCLUSIONS Preoperative biliary drainage did not influence the incidence of postoperative complications, and although it can be performed safely in jaundiced patients it should not be used routinely.

Abstract
Tumor progression after curative resection of gastrointestinal carcinomas is probably caused by pre- or intraoperative tumor cell dissemination. Disseminated tumor cells are generally detected by immunohistochemistry- or PCR-based molecular-biology methods. A consensus on which is the most adequate detection method has not yet been found, which makes the comparison of data difficult. The prognostic relevance of disseminated cells has been shown, at least in part, for esophageal, gastric, pancreatic, and colonic cancer. The data regarding hepatocellular cancer is conflicting. This article gives a critical review of tumor cell detection in gastrointestinal cancer.

Abstract
OBJECTIVE To perform a two-part study of pancreaticoduodenectomy in the Netherlands, focusing on the effects of risk factors on outcomes in a single high-volume hospital and the effect of hospital volume on outcomes. SUMMARY BACKGROUND DATA Hospital volume and surgeon caseload can be related to the rates of complications and death, and the influence of risk factors can be volume-dependent. Provision of regionalized care should take this into account. METHODS In part A, a single-institution database on 300 consecutive patients undergoing pancreaticoduodenectomy was divided into two periods with similar numbers of patients. Overall complications, deaths, hospital stay, and risk factors were analyzed in the two periods and compared with an historical reference group. In part B, Netherlands medical registry data on age and postoperative death of patients who underwent partial pancreaticoduodenectomy from 1994 to 1998 were analyzed for the influence of hospital volume on death. RESULTS Between the time periods, the institutional death rate decreased from 4.9% to 0.7%, the complication rate from 60% to 41%. Median hospital stay decreased from 24 to 15 days. The death rate was not related to patient age and did not differ between surgeons. Serum creatinine levels, need for blood transfusion, and period of resection were independent risk factors for complications. The death rate after pancreaticoduodenectomy in the Netherlands was 12.6% in 1994 and 10.1% in 1998; it was greater in patients older than age 65. During the 5-year period, 40% of the procedures were performed in hospitals performing fewer than five resections per year, and the death rate was greater than in hospitals performing more than 25 resections per year. CONCLUSIONS The overall death rate after pancreaticoduodenectomy did not decrease significantly during the period, and it was greater in low-volume hospitals and older patients. The lower death and complication rates in high-volume hospitals, including the single-center outcomes, were similar to those reported in other countries and may be due to better prevention and management of complications. Pancreaticoduodenectomy should be performed in centers with sufficient experience and resources for support.

Abstract
AIMS Pre-operative endoscopic retrograde cholangiopancreatography (ERCP) with biliary drainage is associated with a greater risk of implantation metastases after resection of proximal bile duct tumours. In a previous study among patients who had undergone biliary drainage before resection, eight patients (20%) developed implantation metastases, within 1 year following resection. The aim of this analysis was to evaluate the results of pre-operative irradiation with regard to a possible reduction of implantation metastases. METHODS Twenty-one patients with proximal bile duct tumours who had undergone resection following pre-operative irradiation were retrospectively analysed. Pre-operative radiation therapy consisted of three fractions of 3.5 Gy external beam irradiation of the hilar area. RESULTS Pre-operative biliary drainage was performed in 19 patients (90%). All patients received pre-operative radiotherapy during which no complications were noted. None of the patients developed implantation metastases within a follow-up time of 2 to 79 months. CONCLUSION The results of this study suggest that pre-operative radiotherapy in patients with a resectable proximal bile duct tumour who have undergone pre-operative drainage, decreases the risk of implantation metastases. To be certain about the role of pre-operative radiotherapy, a randomized study is required. Until then, we advocate standard low dose radiotherapy preceding resection in all patients with lesions suggestive of a proximal bile duct tumour who have undergone biliary drainage.
