RESUMEN
PURPOSE: Radical trachelectomy (RT) with pelvic lymphadenectomy has become a new treatment option for young patients with uterine cervical cancer stages 1A2-1B1 who desire the preservation of their fertility. However, the application of RT for pregnant patients is still controversial. We comparatively studied both obstetrical and oncological outcomes of pregnant patients who underwent vaginal RT during pregnancy and those who underwent vaginal RT before pregnancy. METHODS: Both obstetrical and oncological results of eight patients who underwent vaginal RT with pelvic lymphadenectomy during pregnancy in our institute between 2010 and 2020 (Group A), and ten pregnant patients who underwent vaginal RT with pelvic lymphadenectomy before pregnancy during the same period (Group B) were reviewed based on their medical charts. RESULTS: There were neither significant differences in blood loss, surgical time, or surgical completeness between Group A and Group B, nor were there significant differences in obstetrical outcomes between the two groups. However, two of the eight patients in Group A had recurrence of the cancer. None of the patients in Group B has shown any signs of recurrence thus far. CONCLUSION: Vaginal RT during pregnancy does not affect the obstetrical prognoses of patients with early invasive uterine cervical cancer, and it might be a tolerable treatment modality for them. However, oncologically, it should be performed carefully as there is a risk of recurrence.

A drenagem endoscópica da via biliar em casos inoperáveis de obstrução maligna é a conduta de escolha atualmente. O uso de próteses metálicas autoexpansíveis apresenta melhores resultados em relação às próteses plásticas em virtude dos menores índices de obstrução. No entanto, complicações como colecistite podem ocorrer em até 5% dos casos.

BACKGROUND AND STUDY AIMS: In many patients, percutaneous endoscopic gastrostomy (PEG) can be limited by digestive tract stenosis. PEG placement using an introducer is the safest alternative for this group of patients, but the available devices are difficult to implement and require smaller-caliber tubes. The aim of this study was to evaluate the modification of an introducer technique device for PEG placement with regard to the following: procedure feasibility, possibility of using a 20-Fr balloon gastrostomy tube, tube-related function and problems, complications, procedure safety, and mortality. PATIENTS AND METHODS: Between March 2007 and February 2008, 30 consecutive patients with head and neck malignancies underwent introducer PEG placement with the modified device and gastropexy. Each patient was evaluated for 60 days after the procedure for the success of the procedure, infection, pain, complications, mortality, and problems with the procedure. RESULTS: The procedure was successful in all cases with no perioperative complications. No signs of stomal infection were observed using the combined infection score. The majority of patients experienced mild-to-moderate pain both in the immediate postoperative period and at 72 hours. One major early complication (3.3%) and two minor complications (6.7%) were observed. No procedure-related deaths occurred during the first 60 days after the procedure. CONCLUSION: The device modification for PEG using the introducer technique is feasible, safe, and efficient in outpatients with obstructive head and neck cancer. In this series, it allowed the use of a larger-caliber tube with low complication rates and no procedure-related mortality.

Mixed germ cell tumours of the ovary, one type of malignant ovarian germ cell tumours (MOGCTs), are rare gynaecologic cancers usually affecting young women. We report the case of a patient with an advanced ovarian mixed germ cell tumour who underwent fertility-saving surgery followed by a chemotherapy regimen of cisplatin, vinblastine and peplomycin. The patient was disease-free 8 years after initial presentation. She conceived and gestated dichorionic twins after IVF-embryo transfer. To the best of our knowledge, the patient is the first to be treated successfully with the combination chemotherapy regimen and then conceive safely using assisted reproductive technology (ART).

BACKGROUND: The usual treatment of pyloroduodenal peptic stenosis has been mainly surgical, through pyloroplasty or gastric resection, with or without vagotomy. Since the first description of treatment for this peptic complication by endoscopic balloon dilation perfomed by Benjamin in 1982 [2], this procedure has become a therapeutic option in association with the medical treatment of peptic disease. The aim of this study is to evaluate the results involving clinical, endoscopic, and gastric emptying scintigraphy parameters. METHODS: Between August 1998 and February 2000, 20 patients with pyloroduodenal stenosis refractory to conservative treatment were treated at the Gastrointestinal Endoscopy Unit of the University of São Paulo Medical School. All patients who presented clinical manifestations of pyloroduodenal stenosis underwent upper gastrointestinal endoscopy to confirm peptic stenosis. Biopsy of the narrowing for the confirmation of a benign disease and gastric biopsy for Helicobacter pylori detection were performed. The treatment consisted of dilation of the stenosis with type TTS (Through The Scope) hydrostatic balloon under endoscopic control, treatment of Helicobacter pylori infection, and gastric acid suppression with oral administration of proton pump inhibitor. All patients, except one who was excluded from this study, were submitted to a clinical endoscopic assessment and gastric emptying evaluation by ingestion of (99m)Tc before and after the treatment. Endoscopic evaluation considered the diameter of the stenotic area before and after treatment. A scintigraphic study compared the time of gastric emptying before and after balloon dilation. RESULTS: Nineteen patients completed treatment by hydrostatic balloon dilation. Clinical symptoms such as bloating (p < 0.0001), epigastric pain (p = 0.0159), gastric stasis (p < 0.0001), and weight gain (p = 0.036) showed significant improvement. The diameter of the stenotic area increased significantly (p < 0.01) after the dilation treatment as well as a better gastric emptying of (99m)Tc (p < 0.0001). CONCLUSION: The dilation of the peptic pyloroduodenal stenosis using a hydrostatic balloon is a safe and effective procedure. The evaluation with gastric scintigraphy by ingestion of (99m)Tc is an effective method of assessment for the improvement of gastric function, because its results corresponded to the clinical improvement after endoscopic treatment.

BACKGROUND AND STUDY AIMS: Endoscopic evaluation of the excluded stomach after Roux-en-Y gastric bypass surgery for morbid obesity is a challenge, and the pathological changes that take place in the bypassed stomach are unclear. A new double-balloon method of evaluating the bypassed stomach after Roux-en-Y gastric bypass surgery for morbid obesity is described here. PATIENTS AND METHODS: This new enteroscope uses two balloons, one attached to the tip of the endoscope and the other to the distal end of the soft overtube. The procedures were carried out in six patients using the retrograde route, through the end-to-side jejunal anastomosis via the duodenobiliopancreatic limb up to the bypassed stomach. RESULTS: The bypassed stomach was reached in five of six patients (83.3 %). An endoscopic appearance of atrophic gastritis was found in three patients, mild in two cases and severe in one case with intestinal metaplasia. Erosive and hemorrhagic gastritis was found in two patients. CONCLUSIONS: Endoscopic evaluation of the bypassed stomach via the retrograde route after Roux-en-Y gastric bypass for morbid obesity is feasible using the double-balloon enteroscope.

BACKGROUND AND STUDY AIMS: There have so far been no prospective studies on the value of flexible endoscopy for removing foreign bodies in the upper gastrointestinal tract. This study presents a clinical analysis of accidents with foreign bodies and prospectively evaluates the effectiveness of flexible endoscopy for removing them. PATIENTS AND METHODS: A total of 105 cases of foreign-body ingestion in the upper gastrointestinal tract were evaluated, 29 (27.6 %) in children and 76 (72.4 %) in adults. Thirty patients (28.5 %) had esophageal strictures. RESULTS: Thirty-nine of the foreign bodies (37.1 %) consisted of food and 66 (62.9 %) were not food-related. The success rate of foreign-body extraction using only a conventional flexible endoscope and accessories for treatment was 98.0 %, and with only a polypectomy snare and rat-toothed forceps it was 91.2 %. Complications at the moment of foreign-body removal occurred in nine patients (8.6 %); there was only one (1 %) esophageal perforation. The incidence of complications related to the duration of foreign-body impaction was six (10.5 %) with foreign bodies impacted for up to 24 h, 13 (52.0 %) for those impacted for 24-48 h, and three (60.0 %) for those impacted for 48-72 h ( P < 0.05). CONCLUSIONS: The flexible endoscope is an effective and safe device for removing foreign bodies from the upper gastrointestinal tract, with a high success rate using only the polypectomy snare and the rat-toothed forceps as accessories. If foreign-body impaction lasts for more than 24 h, there is a significant increase in the incidence of complications.

BACKGROUND AND STUDY AIMS: The early detection and accurate staging of pancreatic and ampullary cancer is of utmost importance for the achievement of surgical radical treatment. The aim of this study was to assess prospectively the role of endoscopic ultrasonography (EUS) in detection and staging of pancreatic and ampullary cancer, comparing its results to those obtained with spiral computed tomography (SCT). PATIENTS AND METHODS: Sixty-one patients with suspected pancreatic and ampullary tumors were included, 46 (75, 4%) of whom presented with obstructive jaundice. Patients underwent EUS and SCT within a 7-day period. Examiners were unaware of the previous imaging results, except conventional echography. Image interpretation was compared to surgical and histopathological findings. RESULTS: Fifty-six (91, 8%) patients were surgically explored. Clinical follow-up and/or tissue diagnosis determined the correct diagnosis in the remaining five patients. Pancreatic cancer and ampullary cancer were observed in 29 (47, 6%) and 10 (16, 4%) patients, respectively. Chronic pancreatitis and choledocholithiasis were the most common diagnosis in patients with non-neoplastic disease. EUS was more effective than SCT for the definition of the final diagnosis in patients with obstructive jaundice (87.0 vs. 67.4%, p = 0.04). Both exams were equally effective for detecting pancreatic cancer but EUS predicted more accurately the involvement of portal-mesenteric axis by the tumor (87.0 vs. 67.4%, p = 0.04). EUS was particularly useful in the diagnosis of cancer of papilla of Vater. CONCLUSION: In patients with pancreatic adenocarcinoma without unequivocal signs of distant metastatic disease, EUS is more accurate than SCT to predict venous involvement by the tumor. EUS is superior to SCT to detect ampullary adenocarcinoma. Both methods are equally ineffective to detect nodal involvement in pancreatic and ampullary cancer.

BACKGROUND AND STUDY AIMS: Portal hypertensive gastropathy (PHG) is a common finding in chronic liver disease, but it has not been evaluated in hepatosplenic schistosomiasis, a significant cause of noncirrhotic portal hypertension worldwide. Our study was aimed at comparing cirrhosis with hepatosplenic schistosomiasis with regard to the endoscopic and histological findings of PHG. PATIENTS AND METHODS: We included 43 patients with a history of upper digestive hemorrhage, 22 with cirrhosis and 21 with schistosomiasis, without previous surgical or endoscopic treatment. Upper digestive endoscopies with macrobiopsies of the gastric body were prospectively performed in all cases. RESULTS: The endoscopic signs of PHG were more prevalent in cirrhosis than schistosomiasis (81.8 % vs. 33.3 %; P < 0.05), and the mosaic pattern was the main finding. Histological abnormalities were evenly distributed. CONCLUSIONS: In agreement with other investigations, this study shows a lower prevalence of endoscopic findings of portal hypertensive gastropathy in noncirrhotic diseases. This difference cannot be explained by the underlying microscopic alterations, which were similar in both groups, suggesting that other factors must play a role in its pathogenesis.

BACKGROUND: The feasibility and efficacy of incision of the septum between the pharyngoesophageal (Zenker's) diverticulum and the esophagus with a flexible endoscope and needle-knife have been demonstrated. Exposure of the septum remains a critical element of the procedure. This is a report of a technical improvement in this technique: use of a transparent oblique-end hood attached to the tip of the endoscope. METHODS: Ten patients (10 men, age range 67-87 years) with Zenker's diverticulum were treated. With the aid of an oblique-end hood attached to the tip of the endoscope, the septum between the Zenker's diverticulum and esophagus was incised with pure coagulation current. A 10F nasogastric tube was left in place for 48 hours after the procedure to provide nutrition. Thereafter, oral intake was progressively resumed. RESULTS: Complete incision of the septum was achieved in a single session in all cases. Bleeding or perforation did not occur in this small series. Complete relief of dysphagia was reported by all patients during follow-up that ranged from 2 to 12 months. CONCLUSIONS: With the use of the oblique-end hood attached to the tip of the endoscope, incision of Zenker's diverticulum is simplified and can be performed as a single-session procedure.

A fistulizaçäo cirúrgico-endoscópica no contorno papilar superior é um procedimento destinado a facilitar a cateterizaçäo da porçäo terminal do ducto colédoco, pela impossibilidade do acesso habitual pelo óstio, tendo em vista a fibrose, tumores ou cálculo impacatado. Esse procedimento foi denominado por Schapira (19982) como fístulo-esfincterotomia endoscópica, embora tenha recebido outras denominações inapropriadas, como fistulotomia suprapapilar ou infundibulotomia. Tal intervençäo endoscópica viabiliza a catererizaçäo emcasos difíceis, ampliando o acesso ao colédoco terminal ao nível da ampola hepatopancreática. E difere do procedimento denominado pré-corte, porquanto o óstio da papila é poupado com o intuito de prevenir a pancreatite aguda. Essa intervençäo cirúrgico-endoscópica, com base anatômica, é denominada fístulo-papilotomia no Serviço de Endoscopia Digestiva do HC-FMUSP. No período de outubro de 1999 a dezembro de 2000, foram realizadas 451 papilotomias, sendo indicadas 65 (14,5por cento) fístulo-papilotomias, cuja indicaçäo miais frequente foi a coledocolitíase. Ocorreram nove (13,8por cento) complicações: pancreatite aguda em cinco (7,6por cento) casos, hemoragia em um (1,5por cento), colangite em dois (3por cento) e perfuraçäo retroduodenal em um (1.5por cento). Em todos esses casos houve resoluçäo espontânea através do tratamento conservador. Considerando-se o insucesso da cateterizaçäo do óstio da papila de forma convencional, a fístulo-papilotomia for a opçäo que demonstrou ser um procedimento viável e seguro

The patient was a 59-year-old woman with recurrent ovarian cancer. A CT scan of the abdomen showed enlargement of abdominal para-aortic lymph nodes (PAN) after the primary operation and 8 cycles of the combination chemotherapy with paclitaxel (TXL) and carboplatinum (CBDCA). As a second line chemotherapy for the patient, weekly administration of TXL (60 mg/m2/week x 3 weeks) was given. The toxicity was acceptable and less pronounced than with the standard TXL + CBDCA therapy. Peak blood TXL concentration, about 90 ng/ml, was achieved 4 hours after the administration of TXL. The blood TXL concentration was below the detectable limit 48 h after the administration of TXL. An almost 50% shrinkage in the size of the PAN was obtained after 2 cycles of treatment. Good QOL is being maintained without any repeated aggravation of the tumor.

BACKGROUND AND STUDY AIMS: Despite the recognized efficacy of sclerotherapy and elastic band ligation in controlling variceal hemorrhage, the results of endoscopic treatment in Child-Pugh class C patients remain poor. The aim of this prospective, controlled, and randomized study was to compare conventional sclerotherapy with injection of the tissue adhesive N-butyl-2-cyanoacrylate in controlling the first episode of rupturing of esophageal varices. PATIENTS AND METHODS: From January 1994 to June 1997, 36 consecutive Child-Pugh class C cirrhotic patients were admitted with an initial episode of esophageal variceal bleeding. They were randomly assigned to receive sclerotherapy with a 3% ethanolamine oleate solution (group 1, 18 patients) or injection of tissue adhesive (group 2, 18 patients). Episodes of recurrent bleeding were managed after the randomization procedure. After bleeding had been controlled, patients in both groups received weekly sessions of conventional sclerotherapy to eradicate any remaining esophageal veins. RESULTS: The patients in the two treatment groups had similar characteristics on entry into the study. More than 80% of the patients were admitted with moderate or severe hemorrhage. Approximately half of them presented with active bleeding during the index endoscopy. Early recurrent bleeding was observed in ten of the 18 patients in group 1 (55.6%) and in two of the 18 in group 2 (11.1%; P = 0.01). The hospital mortality rates were 72.2% in group I and 33.3% in group II (P = 0.04). CONCLUSION: These findings support the view that cyanoacrylate injection is superior to conventional sclerosis for controlling esophageal variceal bleeding in Child-Pugh class C patients. It is also highly probable that the better bleeding control achieved using the cyanoacrylate tissue adhesive treatment led to a lower hospital mortality rate.

Polymorphisms at three loci in the thiopurine methyltransferase (TPMT) gene are known to be responsible for azathioprine and 6-mercaptopurine (6MP) toxicity. Among them, only TPMT*3C variant allele with A719G mutation was found in 15/522 (2.9%; 17/1044 alleles; 1.6%) Japanese individuals including two homozygotes. The allele frequency was different from that in Caucasians, and investigation of TPMT polymorphisms with consideration of ethnic differences before administration of azathioprine or 6MP may provide clinically useful information.

Advanced squamous cell carcinoma of the esophagus (SCCE) is usually a disease of dismal prognosis. Palliation of dysphagia is the main goal of its treatment. This trial compared surgical to endoscopic palliation of dysphagia. Forty patients(32:8a, age 39-79y) suffering from TNM stage III or IV SCCE were divided into two groups: 20 patients were submitted to esophagogastric bypass (surgical group), and 20 patients had an endoscopically placed auto-expandable metal stent (EsophaCoil "In stent", Minnesota, USA)(endoscopic group). Both groups were similar regarding demographic data and nutritional status. The palliation of dysphagia, the incidence of early and late complications, the life quality (Karnofsky Index), the survival, the length of inpatient stay and the costs were evaluated in both groups. There was no difference between surgical and endoscopic groups regarding palliation of dysphagia, frequency of complications, quality of life, and survival. Early and late most common postsurgical complications were anastomotic leak and stenosis, respectively. The most common post-endoscopic complications were both late: benign hyperplasia and tumour overgrowth. None of the surgical or endoscopic complications were related to mortality. Hospital length stay and the costs were significantly higher in the surgical group (15.5 days vs 3 days, P < 0.001; U$ 4.690,45 +/- 1.360,28 vs U$ 2.618,24 +/- 944,98 P < 0.001). In conclusion, the endoscopic placement of an esophageal metal stent for the palliation of malignant dysphagia in patients with irresectable disease is equally effective as surgical bypass at lower costs and reduced length of inpatient stay.
