All patientsunderwent staging laparoscopy. The strength ofagreement between computed tomography （CT） stage,endoscopic ultrasound （EUS） stage, laparoscopic stage,and final stage were determined by weighted Kappastatistic （Kw）. The number of patients with treatmentdecision-changes was counted. A χ 2 test was used toanalyze the correlation between peritoneal metastasisor positive cytology and clinical characteristics.RESULTS： Among the 582 patients, the distributions ofpathological T classifications were T2/3 （153, 26.3%）,T4a （262, 45.0%）, and T4b （167, 28.7%）. Treatmentplans for 211 （36.3%） patients were changed after staging laparoscopy was performed. Two （10.5%） of19 patients in M1 regained the opportunity for potentialradical resection by staging laparoscopy. Unnecessarylaparotomy was avoided in 71 （12.2%） patients. Thestrength of agreement between preoperative T stageand final T stage was in almost perfect agreement （Kw= 0.838; 95% confidence interval （CI）： 0.803-0.872;P 〈 0.05） for staging laparoscopy; compared with CTand EUS, which was in fair agreement. The strengthof agreement between preoperative M stage andfinal M stage was in almost perfect agreement （Kw= 0.990; 95% CI： 0.977-1.000; P 〈 0.05） for staginglaparoscopy; compared with CT, which was in slightagreement. Multivariate analysis revealed that tumorsize （≥ 40 mm）, depth of tumor invasion （T4b）, andBorrmann type （Ⅲ or Ⅳ） were significantly correlatedwith either peritoneal metastasis or positive cytology.The best performance in diagnosing P-positive wasobtained when two or three risk factors existed.CONCLUSION： Staging laparoscopy can improvetreatment decision-making for advanced GC anddecrease unnecessary exploratory laparotomy.展开更多

All the patients had a pretreatment 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 up-staged 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 (9R0 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.展开更多

Staging laparoscopy has been suggested as a tool for staging which may spare up to two-fifth of these patients from undergoing nontherapeutic laparotomy. A controversy exists, however, as to whether the procedure should be used routinely or selectively in these patients with no evidence of metastasis on noninvasive staging. This review aims to evaluate the available literature critically, identify its limitations and address the existing controversies. Methods: The current available English literature was reviewed on this topic. Results: A direct and conclusive comparison of the controversial literature is difficult because of inconsistent use of high-quality CT scans, different study designs and dissimilarity of judgment for non-resectability among patients staged by laparoscopy. However, recent studies reveal that not more than 14% of the patients benefit from diagnostic laparoscopy when a dual-contrast thin cut and 3-D digital reformatting CT scan has been performed previously. Conclusion: We conclude that routine use of diagnostic laparoscopy does not appear warranted in all patients with pancreatic cancer, especially for patients with early-staged pancreatic cancer or non-pancreatic periampullary cancers, because diagnostic laparoscopy is costly and ultrasonography is largely operator-dependent. Rather, selective use is appropriate, especially in patients with a large primary tumor, a tumor in the body or tail of the pancreas, equivocal findings of metastasis on CT, the presence of ascites, severe weight loss, hypoalbuminemia, and a markedly elevated CA 19–9.展开更多

The potential to prevent needless laparotomy by means of precise staging is the pouring force behind the use of diagnostic laparoscopy (DL). Objective: To assess the role of laparoscopy and laparoscopic ultrasound (LUS) in proper staging of upper gastro intestinal malignancies, and in potential palliation in advanced cases for pain (by neurolytic celiac plexus block) or gastric outlet obstruction (by laparoscopic bypass surgery). Study design: In this prospective study, 62 patients with lower esophageal, gastric and peri-pancreatic carcinomas were joined after written informed consent. All patients were examined with laparoscopy and LUS with the help of frozen section analysis to any doubtful metastatic site, peritoneal fluid and ascitic fluid analysis. Results: DL helped us to avoid needless laparotomy in 22.5% of patients, reducing its post-operative complications, hospital stay and cost. DL also helped us to do palliative management either in the form of gastric bypass or laparoscopic celiac plexus block. Conclusion: we praise the use of DL as a safe, effective and complimentary method to the other routine imaging modalities, in proper staging and palliation for upper gastrointestinal malignancies.展开更多

This is a case of comprehensive laparoscopic surgical stage of an ovarian dysgerminoma in a 10-year-old girl described. This patient was referred to the gynecology oncology unit status post left salpingo-oophorectomy through a midline incision when the histopathology showed pure dysgerminoma. We then performed the laparoscopic stage including peritoneal washing;resection of the left infundibulopelvic ligament;systematic pelvic, common iliac, and infrarenal bilateral paraaortic lymphadenectomy;and omentectomy. The uterus and right adnexum were spared to preserve future fertility. The final histopathology showed no metastatic disease (stage ovarian dysgerminoma), and patient has no evidence of recurrence after 52 months follow up. Conclusion: This is the youngest patient reported in the literature with a comprehensive laparoscopic surgical stage for ovarian neoplasm. A full laparoscopic staging for ovarian cancer in a 10-year-old girl is safe and might be considered as an alternative to the stander of care.展开更多

Fowlers-Stephens and Shehata methods proposed staged orchidopexy, but are still associated to a rate of atrophy greater than 10%. Purpose: We set out to present a new technique that preserves testicular vessels. Our study is aimed at investigating testicular vitality after surgery. Patients and Method: We reviewed files of boys who underwent orchidopexy for 2 years in our department. Those who have been operated for intra-abdominal cryptorchidism with the new technique and aged between 6 months and 14 years old were included in our study. We excluded boys who have been operated before 6 months and after 14 years old and those who did not respect their follow-up plane. Ultrasound (US) outcomes were used to measure testicular volumes and blood flow at each postoperative visit. The Sample population was divided into group A and group B representing testes that were followed respectively for 12 and 24 months. Results: 22 boys with 25 testes were included in our study;11 testes in group A and 14 testes in group B. In each group, we noted a significant difference of UDT volumes from the third month after surgery with respective P-values 0.05. There was no statistical difference between UDT and contra lateral testes volumes 12 months after surgery in group A and 24 months in group B with respective P-values of 0.07 and 0.72. All volume differential indexes were Conclusion: This method offers a new perspective in performing safe orchidopexy for intra abdominal undescended testes.展开更多
