- LYMPHOCYTE COUNT AND PLATELET VOLUME PREDICTS POSTOPERATIVE COMPLICATIONS IN ESOPHAGECTOMY FOR CANCER: A COHORT STUDY(2019) TUSTUMI, Francisco; TAKEDA, Flávio Roberto; BRANDÃO, Antonio Adolfo Guerra Soares; SALLUM, Rubens Antonio Aissar; RIBEIRO JUNIOR, Ulysses; CECCONELLO, IvanABSTRACT BACKGROUND: Biomarkers from routine complete blood count are known predictive factors of long-term outcomes in cancer patients. The value of these biomarkers in the setting of trimodal therapy for esophageal cancer in predicting early postoperative outcomes is not studied. OBJECTIVE: The present study evaluated the value of cellular blood components changes during neoadjuvant chemoradiotherapy followed by curative intent esophagectomy for cancer in predicting postoperative mortality and morbidity. METHODS: A cohort of 149 consecutive patients that underwent chemoradiotherapy using platinum- and taxane-based regimens followed by esophagectomy was analyzed. Cellular components of blood collected before neoadjuvant therapy (period A) and before surgery (period B) were assessed for postoperative mortality and complications. Univariate and multivariate Cox regression models were applied to evaluate the independent prognostic significance of blood count variables. RESULTS: Postoperative morbidity was present in 46% of the patients. On multiple regression analysis platelet volume (B) (OR: 1.53; 95% CI: 1.2-2.33) was an independent predictor of general complications. Severe postoperative surgical complications were present in 17% of the patients. On multiple regression analysis, lymphocyte decrease between B-A periods (OR: 0.992; 95% CI: 0.990-0.997) was related to higher risk for severe complications. Cervical anastomotic leakage was present in 25.6% of the patients. On univariate analysis eosinophil count in A and B periods was related to cervical anastomotic leakage. For this outcome, multivariate joint model could not identify independent risk variables of cellular components of blood. The 30-day mortality rate was 7.4%. On univariate analysis, platelet count in period B was associated to higher risk for mortality. The multivariate joint model could not accurately predict mortality due to the few number of patients in the mortality group. CONCLUSION: This is the first study to assess the relationship between peripheral blood count variables changes during neoadjuvant chemoradiotherapy using a platinum- and taxane-based regimen followed by curative intent esophagectomy for cancer in predicting postoperative complications. The platelet volume prior to surgery is related to postoperative complications and the lymphocyte count change prior to surgery predicts severe postoperative complications in the setting of trimodal therapy for esophageal cancer.
- TRANSHIATAL ESOPHAGECTOMY IS NOT ASSOCIATED WITH POOR QUALITY LYMPHADENECTOMY(2019) TAKEDA, Flavio Roberto; TUSTUMI, Francisco; NIGRO, Bruna de Camargo; SALLUM, Rubens Antonio Aissar; RIBEIRO-JUNIOR, Ulysses; CECCONELLO, IvanBackground: Esophageal cancer neoadjuvant therapy followed by surgery increases the likelihood of treatment success. Aim: To evaluate variables that can influence the number of retrieved lymph nodes, the number of retrieved metastatic lymph nodes and lymphnodal recurrence in esophagectomy after neoadjuvant chemoradiotherapy. Methods: Patients of a single institute were evaluated after completion of trimodal therapy. Univariate and multivariate analyses were performed to evaluate variables that can influence in the number of retrieved lymph nodes and retrieved metastatic lymph nodes. Results: One hundred and forty-nine patients were included. Thoracoscopy access was considered an independent factor for the number of lymph nodes retrieved, but was neither related to the number of positive lymph nodes retrieved nor to lymphnodal recurrence. Pathological complete response on the primary tumor and male were independent variables associated with the number of positive lymph node retrieved. Pathological complete response on the primary tumor site did not statistically influence the likelihood of a lower number of lymph nodes retrieved. Conclusion: Patients submitted to esophagectomy after neoadjuvant chemoradiotherapy, thoracoscopic access is more accurate for pathological staging, even in a complete pathological response. With a proper patient selection, transhiatal surgery may preserve the quality of lymphadenectomy of the positive lymph nodes.
- Long Term Follow-up Results of Surgical Management of Chronic Pancreatitis(2019) TUSTUMI, Francisco; COSTA, Thiago Nogueira; PENTEADO, Sonia; BACCHELLA, Telesforo; CECCONELLO, IvanBackground: Chronic pancreatitis is a progressive loss of exocrine and endocrine pancreatic function. Surgical procedures are required in cases of intractable pain, biliary obstruction or intestinal obstruction, complications from pseudocysts, or pancreatic fistulae. Objective. To assess the outcomes after surgical management of chronic pancreatitis, in a long-term follow-up. Methods: Patients that underwent surgical management of chronic pancreatitis,from 2006 to 2017, were reviewed. Demographics and complications of the procedures were recorded. Visual analogue pain scale was used for pain control evaluation. The 12-Item Short-Form Health Survey questionnaire was used for quality of life assessment. Results: Sixty-five patients were included in the study. Mean follow-up was 60.26 months. Twenty patients underwent lateral pancreatojejunostomy, 22 to Roux-en-Y cystojejunostomy, 7 to transgastric cyst-gastrostomy,1 to Frey procedure, 4 to hepaticojejunostomy, 1 to Frey procedure and hepaticojejunostomy, 1 to lateral pancreatojejunostomy and cyst-gastrostomy, 7 to lateral pancreatojejunostomy and hepaticojejunostomy and 2 to cystojejunostomy and hepaticojejunostomy. No cases of perioperative deaths were recorded. A Pancreatic fistula was found in 5 cases, and all of them followed non-operative management. Of the 65 patients included in the study, 39 answered the questionnaires. Mean scores on SF-12, physical and mental scales were respectively 42.72 +/- 10.76 and 49.84 +/- 11.75. Conclusion: Surgical management of chronic pancreatitis is safe, with low mortality and morbidity rates. These procedures are effective in assuaging pain and in providing good quality of life.
- A case report of esophageal heterotopic pancreas presenting as recurrent mediastinal abscess, treated by minimally invasive esophagectomy(2019) BIANCHI, Edno Tales; TUSTUMI, Francisco; DUARTE, Andre Fonseca; ORTIZ, Evelin Sanchez; SZACHNOWICZ, Sergio; SEGURO, Francisco Carlos Bernal Costa; SALLUM, Rubens Antonio Aissar; CECCONELLO, IvanINTRODUCTION: Heterotopic pancreas is a rare congenital anomaly. We report a case of esophageal heterotopic pancreas complicated by recurrent mediastinal abscess and treated by minimally invasive resection. PRESENTATION OF CASE: A 31-year-old woman was admitted with a history of recurrent chest pain, dysphagia, and heartburn. CT scan revealed focal confined collection in the lower mediastinum surrounding esophagus. Endoscopic ultrasound revealed a subepithelial lesion. The patient was treated by minimally invasive esophagectomy and made an uneventful postoperative recovery. DISCUSSION: The management of subepithelial lesions would depend on their size, ability to exclude other etiologies and their associated symptoms. The patient, in this case, was obviously symptomatic and accurate differentiation from malignant etiologies could not be accurately made. CONCLUSION: Although pancreatic heterotopia is rare, it should be remembered in the differential diagnosis of various gastrointestinal lesions. (C) 2019 The Author(s).

- Distortion Correction Protocol for 3T Stereotactic Magnetic Resonance Imaging: A Clinical Study(2019) TAVARES, Wagner Malago; TUSTUMI, Francisco; LEITE, Claudia da Costa; GAMARRA, Lionel Fernel; AMARO JUNIOR, Edson; TEXEIRA, Manoel Jacobsen; FRANCA, Sabrina Araujo de; FONOFF, Erich TalamoniBACKGROUND: With application of 3T magnetic resonance imaging (MRI) to functional neurosurgery procedures and given the inherent requirement of millimetric precision, the need to develop a method for correction of geometric image distortion emerged. The aim of this study was to demonstrate clinical safety and practical viability of a correction protocol in patients scheduled to undergo stereotactic procedures using 3T MRI. METHODS: This prospective study comprised 20 patients scheduled to undergo computed tomography (CT) stereotactic functional procedures or encephalic brain lesion biopsies. The CT images were references for MRI geometric accuracy calculations. For each scan, 2 images were obtained: normal and reversed images. Eight distinct points on CT and MRI were selected summing 152 points that were based on a power analysis calculation value >0.999. One patient was excluded because of the inability to find reliable common landmark points on CT and MRI. RESULTS: The distortion range was 0-5.6 mm and increased proportionally with stereotactic isocenter distance, meaning the distortion was greater in the periphery. After correction, the minimum and maximum distortion found was 0 mm and 3.5 mm, respectively. There was no significant difference between CT and MRI corrected x-coordinates (P > 0.05). CONCLUSIONS: The proposed method can satisfactorily correct geometric distortions in clinical 3T MRI studies. Clinical use of the technique can be practical and efficient after software automation of the process. The method can be applied to all spin-echo MRI sequences.

- Surgical Management of Malignant Intestinal Obstruction: Outcome and Prognostic Factors(2019) SOUSA, Jorge Henrique Bento de; BIANCHI, Edno Tales; TUSTUMI, Francisco; LEONARDI, Paulo Cesar; RIBEIRO JUNIOR, Ulysses; CECONELLO, IvanBackground:Malignant intestinal obstruction is a frequent complication in advanced stages cancer patients. The prognosis is poor, with mean survival rate beneath 3 months. Clinical treatment, endoscopic or surgical procedures are options for malignant intestinal obstruction management. There is no generally accepted management strategy. Objectives: To evaluate prognostic factors of patients with malignant intestinal obstruction who underwent surgical treatment. Methods: A retrospective analysis was performed including patients of a single institution with diagnosis of malignant intestinal obstruction. Demographic data, in-hospital stay, postoperative complications, and overall survival were assessed. Logistic regression was used to evaluate associated prognostic factors. Results: Two hundred thirty-three surgeries were performed due to suspicion for malignant intestinal obstruction over a seven-year period. This diagnosis was confirmed in 210 operations (90.1%). The main causes of malignant obstruction were colorectal (49.5%) and gynecological cancer (21.9%). The rate of severe complications was 11.42%. In-hospital mortality rate was 40.95% (CI 95%: 34.16-47.74%). Functional status impairment,high serum urea, and low albumin levels were associated to higher mortality rate. Conclusion: Malignant intestinal obstruction implies poor prognosis, with high in-hospital mortality rate and severe postoperative complications. The decision regarding management of malignant intestinal obstruction must be multimodal and individualized, according to individual prognostic factors.
