RESUMO

Oesophageal cancer is among the ten most common types of cancer worldwide. More than 80% of the cases and deaths related to the disease occur in developing countries. Local socio-economic, epidemiologic and healthcare particularities led us to create a Brazilian guideline for the management of oesophageal and oesophagogastric junction (OGJ) carcinomas. The Brazilian Group of Gastrointestinal Tumours invited 50 physicians with different backgrounds, including radiology, pathology, endoscopy, nuclear medicine, genetics, oncological surgery, radiotherapy and clinical oncology, to collaborate. This document was prepared based on an extensive review of topics related to heredity, diagnosis, staging, pathology, endoscopy, surgery, radiation, systemic therapy (including checkpoint inhibitors) and follow-up, which was followed by presentation, discussion and voting by the panel members. It provides updated evidence-based recommendations to guide clinical management of oesophageal and OGJ carcinomas in several scenarios and clinical settings.

RESUMO

Gastric cancer is among the ten most common types of cancer worldwide. Most cases and deaths related to the disease occur in developing countries. Local socio-economic, epidemiologic and healthcare particularities led us to create a Brazilian guideline for the management of gastric carcinomas. The Brazilian Group of Gastrointestinal Tumors (GTG) invited 50 physicians with different backgrounds, including radiology, pathology, endoscopy, nuclear medicine, genetics, oncological surgery, radiotherapy and clinical oncology, to collaborate. This document was prepared based on an extensive review of topics related to heredity, diagnosis, staging, pathology, endoscopy, surgery, radiation, systemic therapy and follow-up, which was followed by presentation, discussion, and voting by the panel members. It provides updated evidence-based recommendations to guide clinical management of gastric carcinomas in several scenarios and clinical settings.

RESUMO

BACKGROUND AND AIMS: Submucosal injection of a viscoelastic solution prolongs submucosal lift, thus, facilitating endoscopic mucosal resection. Our objective was to assess the safety and clinical effectiveness of 0.4% hydroxypropyl methylcellulose (HPMC) as a submucosal injectant for endoscopic mucosal resection. PATIENTS AND METHODS: A prospective, open-label, multicenter, phase 2 study was conducted at 2 academic institutions in Brazil. Eligible participants included patients with early gastrointestinal tumors larger than 10 mm. Outcomes evaluated included complete resection rates, volume of HPMC injected, duration of the submucosal cushion as assessed visually, histology of the resected leisons, and complication rates. RESULTS: Over a 12-month period, 36 eligible patients with superficial neoplastic lesions (stomach 14, colon 11, rectum 5, esophagus 3, duodenum 3) were prospectively enrolled in the study. The mean size of the resected specimen was 20.4 mm (10 to 60 mm). The mean volume of 0.4% HPMC injected was 10.7 mL (range 4 to 35 mL). The mean duration of the submucosal fluid cushion was 27 minutes (range 9 to 70 min). Complete resection was successfully completed in 89%. Five patients (14%) developed immediate bleeding requiring endoclip and APC application. Esophageal perforation occurred in 1 patient requiring surgical intervention. There were no local or systemic adverse events related to HPMC use over the follow-up period (mean 2.2 mo). CONCLUSION: HPMC solution (0.4%) provides an effective submucosal fluid cushion and is safe for endoscopic resection of early gastrointestinal neoplastic lesions.

RESUMO

BACKGROUND AND AIMS: Both endoscopic and surgical drainage procedures are effective palliative methods for malignant biliary obstruction. Surgical drainage is still preferred in developing countries due to the high cost of procuring metal biliary stents. The aim of this study was to evaluate the quality of life and the cost of care in patients with metastatic pancreatic cancer after endoscopic biliary drainage and surgical drainage. PATIENTS AND METHODS: This is a prospective, randomized controlled trial conducted in a tertiary referral center in Brazil. Patients with biliary obstruction due to metastatic pancreatic cancer and liver metastasis, but without gastric outlet obstruction, were included in the study. Endoscopic biliary drainage with the insertion of a metal stent into the bile duct was compared with the surgical drainage procedure (choledochojejunostomy and gastrojejunostomy). Quality of life was assessed before, and 30 days, 60 days, and 120 days after the drainage procedure. The cost of drainage procedure, cost during the first 30 days and the total cost from drainage procedure to death were calculated. RESULTS: Of the 273 patients with pancreatic malignancy seen at our hospital between July 2001 and October 2004, 35 patients were eligible for the study, and 30 agreed to participate in the study. Both surgical and endoscopic drainage procedures were successful, without any mortality in the first 30 days. The cost of biliary drainage procedure (US dollars 2,832 +/- 519 vs 3,821 +/- 1,181, p= 0.031), the cost of care during the first 30 days after drainage (US dollars 3,122 +/- 877 vs 6,591 +/- 711, p= 0.001), and the overall total cost of care that included initial care and subsequent interventions and hospitalizations until death (US dollars 4,271+/- 2,411 vs 8,321 +/- 1,821, p= 0.0013) were lower in the endoscopy group compared with the surgical group. In addition, the quality of life scores were better in the endoscopy group at 30 days (p= 0.042) and 60 days (p= 0.05). There was no difference between the two groups in complication rate, readmissions for complications, and duration of survival. CONCLUSIONS: Endoscopic biliary drainage is cheaper and provides better quality of life in patients with biliary obstruction and metastatic pancreatic cancer.

RESUMO

Intrahepatic stone disease poses a difficult postoperative management problem due to frequent stone recurrence. Most of the methods proposed for long-term access to the intrahepatic biliary tree require multiple sessions of additional, usually invasive, procedures. An alternative method for endoscopic long-term access to the intrahepatic ducts, represented by a side-to-side anastomosis between the isolated Roux-en-Y jejunal limb of the bilioenteric bypass and the duodenum (duodenojejunostomy), was used in eight patients with retained and/or recurrent stones after surgical treatment of intrahepatic stone disease. There were no short- or long-term complications or mortality associated with the duodenojejunostomy. Postoperative endoscopic access to the intrahepatic ducts was successfully achieved in five of six patients: one with stone recurrence, one with a left hepatic duct stricture and stone recurrence and one with known retained postoperative stones. In two patients, no stones were found at endoscopy. Side-to-side duodenojejunostomy may be useful in the long-term endoscopic management of recurrent intrahepatic biliary stone disease and should be indicated whenever a bilioenteric anastomosis is performed for the treatment of bilateral intrahepatic stone disease.
