RESUMO

BACKGROUND: Watch-and-wait strategy has been increasingly accepted for patients with clinical complete response (cCR) after multimodal treatment for locally advanced rectal adenocarcinoma. Close follow-up is essential to the early detection of local regrowth. It was previously demonstrated that probe-based confocal laser endomicroscopy (pCLE) scoring using the combination of epithelial and vascular features might improve the diagnostic accuracy of cCR. AIM: To validate the pCLE scoring system in the assessment of patients with cCR after neoadjuvant chemoradiotherapy (nCRxt) for advanced rectal adenocarcinoma. METHODS: Digital rectal examination, pelvic magnetic resonance imaging (MRI), and pCLE were performed in 43 patients with cCR, who presented either a scar (N = 33; 76.7%) or a small ulcer with no signs of tumor, and/or biopsy negative for malignancy (N = 10; 23.3%). RESULTS: Twenty-five (58.1%) patients were men, and the mean age was 58.4 years. During the follow-up, 12/43 (27.9%) patients presented local regrowth and underwent salvage surgery. There was an association between pCLE diagnostic scoring and final histological report (for patients who underwent surgical resection) or final diagnosis at the latest follow-up (p = 0.0001), while this association was not observed with MRI (p = 0.49). pCLE sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 66.7%, 93.5%, 80%, 88.9%, and 86%, respectively. MRI sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 66.7%, 48.4%, 66.7%, 78.9%, and 53.5%, respectively. CONCLUSIONS: pCLE scoring system based on epithelial and vascular features improved the diagnosis of sustained cCR and might be recommended during follow-up. pCLE might add some valuable contribution for identifying local regrowth. Trial Registration This protocol was registered at the Clinical Trials (ClinicalTrials.gov identifier NCT02284802).

RESUMO

BACKGROUND AND AIMS: Colorectal endoscopic vacuum therapy (CR EVT) is usually performed using sponges passed through the anus. It may be associated with patient discomfort and displacement of the aspiration tube. METHODS: With the tube-in-tube endoscopic vacuum therapy modification (CR TT-EVT), it is possible to position the aspiration tube in the pelvic cavity through the abdominal wall. In addition, it allows frequent cleaning of the fistula, eliminates the need for programmed device changes, and enables a standardized approach to such a wide variety of fistulas, leaks, and perforations. RESULTS: Here is a technical note on how to perform CR TT-EVT, while we are at the early phase of our case series we have reached 100% of technical success.

RESUMO

In Malignant Hilar Biliary Stricture (MHBS) palliative biliary drainage is a frequent strategy, improving the quality of life, reducing pruritus, loss of appetite and relieving cholangitis. The endoscopic approach is an effective, although challenging procedure. This study aimed to evaluate technical and clinical success rates of biliary drainage by ERCP. This is a retrospective study including all patients with MHBS referred to Instituto do Cancer do Hospital de São Paulo (ICESP) submitted to biliary drainage by ERCP, between January 2010 and December 2017. Multivariable logistic regression was performed to evaluate predictors of clinical failure, as total bilirubin levels, Bismuth classification, number of hepatic sectors drained and presence of cholangitis. In total, 82 patients presenting unresectable MHBS were included in this study. 58.5% female and 41.5% male, with a mean age of 60±13 years. Bismuth classification grades II, IIIA, IIIB and IV were noted in 23.2%, 15.9%, 14.6% and 46.3%, respectively. Technical and clinical success was achieved in 92.7% and 53.7% respectively. At multivariable logistic-regression analyses, Bismuth IV strictures were related to higher clinical failure rates when compared to other strictures levels, with an Odds Ratio of 5.8 (95% CI 1.28‒20.88). In conclusion, endoscopic biliary drainage for malignant hilar biliary stricture had a high technical success but suboptimal clinical success rate. Proximal strictures (Bismuth IV) were associated with poor drainage outcomes.

RESUMO

Background and study aims Upper gastrointestinal bleeding (UGIB) from malignancy is associated with high rebleeding and mortality rates. Recently, TC-325 powder has shown promising results in the treatment of UGIB, including malignant bleeding. The aim of this study was to compare the efficacy of TC-325 versus best clinical management. Patients and methods From August 2016 to February 2020, all patients with evidence of UGIB from malignancy were randomized to receive TC-325 therapy or control group, in which endoscopic treatment was not mandatory. Exclusion criteria were hemoglobin drop without overt bleeding and UGIB from non-tumor origin. The primary outcome was 30-day mortality. Secondary outcomes were 30-day rebleeding, blood transfusion and length of hospital stay. Results Sixty-two patients were randomized, three were excluded and 59 were included in the final analysis (TC-325 group = 28; control = 31). Groups were similar at baseline. Active bleeding was observed in 22 patients in the TC-325 group and 19 in the control group ( P  = 0.15). Successful initial hemostasis with TC-325 was achieved in all cases. Additional therapy (radiotherapy, surgery or arterial embolization) was equally performed in both groups (42.9 % vs 58.1 %; P  = 0.243). There were no differences in 30-day mortality (28.6 % vs. 19.4 %, P  = 0.406) or 30-day rebleeding rates (32.1 % vs. 19.4 %, P  = 0.26). Logistic regression identified no significant predictors of rebleeding. Age, Eastern Cooperative Oncology Group (ECOG) score 3 to 4 and AIMS65 score > 1 predicted greater mortality. Conclusions TC-325 was effective in achieving immediate hemostasis in malignant gastrointestinal bleeding but did not reduce 30-day mortality, 30-day rebleeding, blood transfusion or length of hospital stay. Age, ECOG 3-4, and AIMS65 > 1 were predictive factors of mortality.

RESUMO

Background and study aims Patients with head and neck squamous cell carcinoma (HNSCC) are at risk of a second primary tumor in the gastrointestinal tract, most commonly in the esophagus. Screening these patients for esophageal carcinoma may help detect asymptomatic dysplasia and early cancer, thus allowing curative treatment and more prolonged survival, but the impact of endoscopic screening remains uncertain. Here we aimed to describe the long-term results of an esophageal SCC screening program in patients with head and neck cancer in terms of prevalence, associated risk factors, and survival. Patients and methods We performed an observational study of a prospectively collected database including patients with HNSCC who had undergone high-definition endoscopy with chromoscopy between 2010 and 2018 at a Brazilian tertiary academic center. Results The study included 1,888 patients. The esophageal SCC prevalence was 7.9 %, with the majority (77.8 %) being superficial lesions. Significant risk factors for esophageal high-grade dysplasia (HGD) and invasive cancer included tumors of the oral cavity and oropharynx and the presence of low-grade dysplasia (LGD). Overall survival (OS) was significantly shorter among patients in whom esophageal cancer was diagnosed at an advanced stage ( P  < .001). OS did not significantly differ between patients with HGD and early esophageal cancer versus those without esophageal cancer ( P  = .210) Conclusions Endoscopic screening for superficial esophageal neoplasia in patients with HNSCC improves esophageal cancer detection. Screening could potentially benefit patients with primary cancer located at the oropharynx or oral cavity. In addition, the detection of esophageal LGD indicates a need for endoscopic surveillance.

RESUMO

BACKGROUND: Neoadjuvant chemoradiotherapy (nCRxt) followed by radical surgery is the optimal treatment for advanced rectal adenocarcinoma. Patients with clinical complete response (cCR) may be followed closely without immediate surgery. Probe-based confocal laser endomicroscopy (pCLE) is a real-time in vivo method that allows acquisition of optical biopsies with 1000 times magnification, evaluating both epithelial and vascular patterns. AIM: To evaluate the role of pCLE in the diagnosis of cCR after nCRxt for advanced rectal adenocarcinoma. METHODS: pCLE was performed in 47 patients with locally advanced rectal adenocarcinoma (T3/T4, or N+) who underwent nCRxt (5-fluorouracil, 5040 cGy). RESULTS: Twenty-seven (57.5%) patients were men, and the mean age was 62.8 years. Thirty-seven had partial response confirmed by pCLE. Ten (21.3%) patients had good endoscopic response and presented small ulcer (n = 5) or residual scar (n = 5). After nCRxt, the essential features to differentiate malignancy from post-radiation alterations at pCLE were the presence of irregular crypts, budding, back-to-back glands, cribriform pattern, increased vessel/crypt ratio, and fluorescein leakage. A scoring system was created considering these epithelial and vascular features, with high accuracy for differentiating patients with complete response from those with residual neoplasia (p < 0.00001). pCLE sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100%, 71.4%, 95.2%, 100%, and 95.7%, respectively. CONCLUSIONS: (1) pCLE evaluation of epithelial and vascular features may improve the diagnosis of cCR and may alter patient management; (2) pCLE might be valuable for identifying patients with advanced rectal cancer who will benefit from watch and wait strategy, avoiding immediate surgical treatment.

RESUMO

INTRODUCTION: EUS-guided gastroenterostomy (EUS-GE) is a novel procedure for palliation of malignant gastric outlet obstruction (GOO). Our aim was to evaluate the outcomes of this technique in our initial experience. METHODS: Patients with GOO from our institute were included. Technical success was defined as the successful creation of a gastroenterostomy. Clinical success was defined as the ability to tolerate a soft diet after the procedure. We assessed adverse events and diet tolerance 1 month after the procedure. RESULTS: Three patients were included. Technical and clinical success was achieved in all cases. There were no adverse events and good diet tolerance was observed 1 month after the procedure in the included patients. CONCLUSION: EUS-GE is a promising treatment for patients with GOO.

RESUMO

INTRODUCTION: Esophagectomy is a challenging procedure associated with considerable morbidity. Previous pulmonary diseases, such as histoplasmosis fungal infection, may interfere in operative and postoperative outcomes after esophagectomy. Anastomotic leakage is one of the most feared complications after esophagectomy. However, new therapies developed such as vacuum procedure and esophageal prosthesis have been provenly beneficial. PRESENTATION OF CASE: We present a case with squamous cell carcinoma of the mid esophagus portion on a young patient with a pulmonary histoplasmosis history. After a multidisciplinary board, the patient underwent transhiatal esophagectomy with gastric-pull up and cervical anastomosis due to pulmonary disease. The patient later developed an anastomotic leak with mediastinal abscess. We describe this complication's management via an endoscopic vacuum system, esophageal prosthesis, and exhibit a video illustrating the technique. DISCUSSION: We illustrate the management of esophageal cancer associated with previous pulmonary disease. Histoplasmosis may misunderstand the esophageal cancer staging, and it can contribute to anastomotic leakage occurrence. An endoscopic vacuum system is an excellent tool for treating esophagogastric anastomosis fistula after esophagectomy, even when the drainage is accumulated in the mediastinum. The esophageal prosthesis may be used after mediastinal abscess resolution. CONCLUSION: Treatment of the association of esophageal cancer and histoplasmosis is feasible. However, care should be taken to avoid highly potential postoperative complications.

RESUMO

BACKGROUND: Management of pharyngoesophageal stenosis (PES) in patients after head and neck cancer (HNC) treatment remains a challenge. It is not uncommon that PES is refractory to dilation sessions. This study aimed at evaluating the efficacy of Mitomycin C (MMC) endoscopic injection for the treatment of refractory pharyngoesophageal stenosis. PATIENTS AND METHODS: This is a prospective study in patients with dysphagia following head and neck cancer treatment, without evidence suggestive of tumor recurrence, and refractory to endoscopic treatment. These patients were submitted to endoscopic dilation of the stenotic segment with thermoplastic bougies, followed by injection of MMC. We repeated the endoscopic sessions every three weeks. RESULTS: From January 2015 to May 2015, we treated 13 patients with PES. Three patients were initially enrolled in the study for refractory stricture. We observed adverse events in all of them, with intense neck pain and ulcer development, justifying the interruption of the trial. CONCLUSION: The repeated injection in the short interval of MMC in refractory PES is not recommended, because it resulted in serious adverse events.

RESUMO

BACKGROUND AND AIMS: Self-expandable metallic stents are considered the best palliative treatment of dysphagia for patients with advanced esophageal cancer. Adverse events (AEs) are a major concern, especially in patients with better prognosis and longer survival. The present study aimed to evaluate the AEs of patients who survived longer than 6 months with esophageal stents in place. METHODS: This is a retrospective analysis of a prospectively collected database including all patients submitted to esophageal stent placement for the palliation of malignant diseases during the period from February 2009 to February 2014 at a tertiary care academic center who had stents longer than 6 months. RESULTS: Sixty-three patients were included. Mean follow-up was 10.7 months. Clinical success was achieved in all patients, and the median stent patency was 7.1 months. AEs occurred in 40 patients (63.5%), totaling 62 AEs (mean, 1.5 AEs per patient). Endoscopic management of AEs was successful in 84.5% of cases, with a mean of 1.6 reinterventions per patient. The univariate analysis revealed that performance status, age, and post-stent radiotherapy presented a trend to higher risk of AEs. The multivariate analysis revealed that only performance status was associated with AEs (P = .025; hazard ratio, 4.1). CONCLUSIONS: AEs are common in patients with long-term esophageal stenting for malignancy. However, AEs were not related to higher mortality rate, and most AEs could be successfully managed by endoscopy. Only performance status was a risk factor for AEs. Our data suggest that metallic stenting is a valid option for the treatment of malignant esophageal conditions, even when survival longer than 6 months is expected.

RESUMO

BACKGROUND AND AIMS: Surveillance programs of patients with head and neck cancer (HNC) detect synchronous or metachronous esophageal squamous cell carcinoma (ESCC) in up to 15% of patients. Noninvasive, probe-based confocal laser endomicroscopy (pCLE) technique may improve the diagnosis allowing acquisition of high-resolution in vivo images at the cellular and microvascular levels. The aim of this study was to evaluate the accuracy of pCLE for the differential diagnosis of nonneoplastic and neoplastic Lugol-unstained esophageal lesions in patients with HNC. METHODS: Twenty-seven patients with HNC who exhibited Lugol-unstained esophageal lesions at surveillance endoscopy were prospectively included for pCLE. Diagnostic pCLE was followed by subsequent biopsies or endoscopic resection of suspected lesions. A senior pathologist was blinded to the pCLE results. RESULTS: Patients mean age was 59 years (SD = 8.8) and 70.4% were men. All patients were smokers, and 22 patients (81.5%) had a history of alcohol consumption. The locations of HNC were oral cavity (n = 13), larynx (n = 10), and pharynx (n = 4). Thirty-seven lesions in 27 patients were studied. The final diagnoses were ESCC in 17 patients and benign lesions in 20 patients. Sensitivity, specificity, and accuracy of pCLE for the histologic diagnosis of ESCC in patients with HNC were 94.1%, 90.0%, and 91.9%, respectively. CONCLUSIONS: First, pCLE is highly accurate for real-time histology of Lugol-unstained esophageal lesions in patients with HNC. Second, pCLE may alter the management of patients under surveillance for ESCC, guiding biopsies and endoscopic resection, avoiding further diagnostic workup or therapy of benign lesions.

RESUMO

BACKGROUND: The endoscopic use of argon plasma coagulation (APC) to achieve hemostasis for upper gastrointestinal tumor bleeding (UGITB) has not been adequately evaluated in controlled trials. This study aimed to evaluate the efficacy of APC for the treatment of upper gastrointestinal bleeding from malignant lesions. METHODS: Between January and September 2011, all patients with UGITB underwent high-potency APC therapy (up to 70 Watts). This group was compared with a historical cohort of patients admitted between January and December 2010, when the endoscopic treatment of bleeding malignancies was not routinely performed. Patients were stratified into two categories, grouping the Eastern Cooperative Oncology Group (ECOG) performance status scale: Category I (ECOG 0-2) patients with a good clinical status and Category II (ECOG 3-4) patients with a poor clinical status. RESULTS: Our study had 25 patients with UGITB whom underwent APC treatment and 28 patients whom received no endoscopic therapy. The clinical characteristics of the groups were similar, except for endoscopic active bleeding, which was more frequently detected in APC group. We had 15 patients in the APC group whom had active bleeding, and initial hemostasis was obtained in 11 of them (73.3%). In the control group, four patients had active bleeding. There were no differences in 30-day re-bleeding (33.3% in the APC group versus 14.3% in the control group; p = 0.104) and 30-day mortality rates (20.8% in the APC group, versus 42.9% in the control group; p = 0.091). When patients were categorized according to their ECOG status, we found that APC therapy had no impact in re-bleeding and mortality rates (Group I: APC versus no endoscopic treatment: re-bleeding p = 0.412, mortality p = 0.669; Group II: APC versus no endoscopic treatment: re-bleeding p = 0.505, mortality p = 0.580). Hematemesis and site of bleeding located at the esophagus or duodenum were associated with a higher 30-day mortality. CONCLUSIONS: Endoscopic hemostasis of UGITB with APC has no significant impact on 30-day re-bleeding and mortality rates, irrespective of patient performance status.
