Intestinal intussusception and occlusion caused by small bowel polyps in the Peutz-Jeghers syndrome. Management by combined intraoperative enteroscopy and resection through minimal enterostomy: case report

The Peutz-Jeghers syndrome is a hereditary disease that requires frequent endoscopic and surgical intervention, leading to secondary complications such as short bowel syndrome. CASE REPORT: This paper reports on a 15-year-old male patient with a family history of the disease, who underwent surgery for treatment of an intestinal occlusion due to a small intestine intussusception. DISCUSSION: An intra-operative fiberscopic procedure was included for the detection and treatment of numerous polyps distributed along the small intestine. Enterotomy was performed to treat only the larger polyps, therefore limiting the intestinal resection to smaller segments. The postoperative follow-up was uneventful. CONCLUSION: We point out the importance of conservative treatment for patients with this syndrome, especially those who will undergo repeated surgical interventions because of clinical manifestation while they are still young.

Microlaparoscopy in gynecology: analysis of 16 cases and review of literature

Microlaparoscopy represents the development of endoscopic surgery towards a minimally invasive surgical procedure. The advantages include fewer surgical complications, faster return to daily activities, more comfortable postoperative recovery, and satisfactory aesthetic results. The possibility of performing surgery under sedation may result in shorter hospitalization, lower hospital costs, and easier anesthetic procedures. The authors report their preliminary experience with the use of microlaparoscopy, using optics and 2mm instruments, as well as a review of the literature since the introduction of this new technique. The report of these 16 cases demonstrates that microlaparoscopy is a feasible technique with satisfactory results. On the other hand, this new technique requires precise indications and a training period for the development of the skills necessary for performing these surgeries.

Low efficacy of an ultra-short term, once-daily dose triple therapy with omeprazole, azithromycin, and secnidazole for Helicobacter pylori eradication in peptic ulcer

PURPOSE: To determine the eradication rate of an ultra-short treatment schedule for Helicobacter pylori infection in a population with peptic ulcers, using omeprazole, secnidazole, and azithromycin in a once-daily dose for 3 days. METHODS: Thirty patients with peptic ulcer diagnosed by upper endoscopy and for Helicobacter pylori infection by rapid urease test and histologic examination received omeprazole 40 mg, secnidazole 1000 mg, and azithromycin 500 mg, administered once daily for 3 days. A follow-up exam was performed 12 weeks after the end of the treatment. Patients who were negative for Helicobacter pylori infection by rapid urease test and histologic examination were considered cured. RESULTS: Patients were predominantly female, and the mean age was 50 years. Duodenal peptic ulcer was found in 73% of the patients. Eradication was achieved in 9 of the 28 (32%) patients as determined from the follow-up endoscopic exam. The eradication rate by intention to treat was 30%. Side effects were present in 3% of the patients, and compliance to treatment was total. CONCLUSIONS: In spite of the low rate of side effects and good compliance, the eradication index was low. A possible drawback of this therapy is that it reduces the efficacy of macrolide and nitroimidazole compounds in subsequent treatments.

Complications of tracheobronchial foreign body aspiration in children: report of 5 cases and review of the literature

Foreign body aspiration (FBA) is one of leading causes of death in children, especially among those younger than 3 years of age. The inhalation of a foreign body may cause a wide variety of symptoms, and early diagnosis is highly associated with the successful removal of the inhaled foreign material. Despite the great advances in endoscopic procedures and anesthesia, a large number of difficulties and complications still result from foreign body aspiration. We describe 5 cases of serious acute complications following aspiration of foreign bodies that became lodged in the tracheobronchial tree, including pneumomediastinum, pneumothorax, total atelectasis, foreign body dislodgment, and need for thoracotomy in children admitted into our intensive care unit in 1999 and 2000; these were all situations that could have been prevented with early recognition and prompt therapeutic intervention.

Omeprazole, Furazolidone, and Tetracycline: an eradication treatment for resistant H. pylori in Brazilian patients with peptic ulcer disease

OBJECTIVES: To determine the efficacy of a simple, short-term and low-cost eradication treatment for Helicobacter pylori (H. pylori) using omeprazole, tetracycline, and furazolidone in a Brazilian peptic ulcer population, divided into 2 subgroups: untreated and previously treated for the infection. PATIENTS AND METHODS: Patients with peptic ulcer disease diagnosed by endoscopic examination and infected by H. pylori diagnosed by the rapid urease test (RUT) and histological examination, untreated and previously unsuccessfully treated by macrolides and nitroimidazole, were medicated with omeprazole 20 mg daily dose and tetracycline 500 mg and furazolidone 200 mg given 3 times a day for 7 days. Another endoscopy or a breath test was performed 12 weeks after the end of treatment. Patients were considered cured of the infection if a RUT and histologic examination proved negative or a breath test was negative for the bacterium. RESULTS: Sixty-four patients were included in the study. The women were the predominant sex (58%); the mean age was 46 years. Thirty-three percent of the patients were tobacco users, and duodenal ulcer was identified in 80% of patients. For the 59 patients that underwent follow-up examinations, eradication was verified in 44 (75%). The eradication rate for the intention-to-treat group was 69%. The incidence of severe adverse effects was 15%. CONCLUSION: The treatment provides good efficacy for H. pylori eradication in patients who were previously treated without success, but it causes severe adverse effects that prevented adequate use of the medications in 15% of the patients.

Conservative therapies for hemorrhagic radiation proctitis: a review

Chronic radiation proctitis represents a challenging condition seen with increased frequency due to the common use of radiation for treatment of pelvic cancer. Hemorrhagic radiation proctitis represents the most feared complication of chronic radiation proctitis. There is no consensus for the management of this condition despite the great number of clinical approaches and techniques that have been employed. Rectal resection represents an available option although associated with high morbidity and risk of permanent colostomy. The effectiveness of nonoperative approaches remains far from desirable, and hemorrhagic recurrence represents a major drawback that leads to a need for consecutive therapeutic sessions and combination of techniques. We conducted a critical review of published reports regarding conservative management of hemorrhagic chronic radiation proctitis. Although prospective randomized trials about hemorrhagic radiation proctitis are still lacking, there is enough evidence to conclude that topical formalin therapy and an endoscopic approach delivering an argon plasma coagulation represent available options associated with elevated effectiveness for interruption of rectal bleeding in patients with chronic radiation proctitis.

Typical and atypical presentations of paranasal sinus mucocele at computed tomography

Mucoceles are cystic masses that generally affect the sinuses. It occurs as a result from obstruction of the ostium of a sinus and consequential accumulation of mucus. Frontal and ethmoid sinuses are mostly affected. Usually, the clinical symptoms are insidious, varying with the extent of the affected region. The treatment is surgical and endoscopic surgery is the method of choice in most cases. The present study is aimed at describing the main characteristics of paranasal sinuses mucoceles, demonstrating and illustrating a series of atypical presentations with emphasis on imaging findings.

Conduta terapêutica atual no adenocarcinoma da cárdia e da junção esofagogástrica

Adenocarcinomas of the cardia and gastroesophageal junction are peculiar entities with three different origins, which differ somewhat from other adenocarcinomas of the stomach in their clinical presentation and pathogenesis, and have a poorer prognosis. In this article the authors reviewed definitions, incidence and epidemiology, etiologic factors, genetic implications, clinical presentation, diagnosis, staging and treatment, with emphasis on the surgical approach, discussing the current management of these cancers. The prognostic factors related specifically to the cardia cancers are: esophageal invasion greater than 3cm, microscopic residual tumor and wall penetration (>T2). Preoperative workup should include computed tomography, and endoscopic ultrasonography and laparoscopy when available. Preoperative recognition of T3/ T4/N2 lesions should indicate inclusion in neo-adjuvant protocols whenever possible. The authors present the results of 46 resected cases of adenocarcinomas of the cardia and GE junction of the Instituto Nacional do Câncer- Brazil (1981-1995). Cure was intended in 29 and palliation in 17 patients. The most common type of resection was total gastrectomy with abdominal esophagectomy (28 cases). Morbidity (major and minor) occurred in 50% of the patients. The main causes were of respiratory origin and fistulas (19.6% each). Death occurred in 44% of the patients with fistula. Postoperative death until the 30th day occurred in 17.24% of the curative cases and in 23.52% of the palliative ones. The median survival time was 68.5 months for stage I, 25 months for stage II, 31 months for stage III and 12.5 months for stage IV diseases. The median survival time was 8 months for palliation and 28.5 months for cure. No long-term survival was obtained with the palliative group, whereas 25% survived five years of more in the curative group. The authors conclude that the surgical approach should be the one the surgeon feels more comfortable with. Complete removal of the disease proved by frozen section, splenectomy and D2 lymphadenectomy should be the standard therapy with curative intent.

Síndrome da alça aferente com necrose simulando pseudocisto de pâncreas

Afferent loop obstruction after gastrectomy and Billroth II reconstruction is an uncommon problem. Complete acute obstruction requires emergent laparotomy. We describe a patient who developed acute abdominal pain, hyperamylasemia, and palpable abdominal mass, five years after Billroth II gastrectomy. At laparotomy the patient was found to have a complete stricture of the afferent limb with evidence of strangulation and necrosis. There was no evidence of pancreatitis or pancreatic pseudocyst. The patient underwent pancreaticoduodenectomy plus degastrectomy and died 18 hours after the procedure in the ICU. The mass was initially inte1preted as pancreatic pseudocyst. Ultrasonography may provide enough evidence to differentiate a pancreatic pseudocyst. from an obstructed afferent loop, by the presence of a peripancreatic cystic mass or debris within the mass or the absence of the keyboard sign, suggesting effacement of the valvulae conniventes of the small bowel. Howewer, CT scan of the abdomen has been suggested to be highly characteristic, if not pathognomonic, for an obstructed afferent loop and should be considered first in patients with pancreatitis after Billroth II gastrectomy. A history of previous gastrectomy, recurrent or severe abdominal pain, hyperamylasemia with characteristic tomography, and endoscopic findings will establish the diagnosis and necessitate surgical evaluation and intervention.

Hepatectomia regrada por videolaparoscopia

With the improvement of laparoscopic techniques, endoscopic liver surgery has become feasible. While laparoscopic wedge liver resection are performed more frequently, laparoscopic (anatomical or nonanatomical) liver resection are still at an early stage of development and are somewhat controversial. We reporte laparoscopic hepatic resection without use of sophisticated laparoscopic instruments. A 47-year-old woman underwent radical mastectomy for adenocarcinoma in 1995. 1n the postoperative follow-up presented, a lesion in the left hepatic lobe and, after laparoscopic approach, left lateral segmentectomy was performed. The hepatic resection elapsed without complications. The surgical time was 4 hours and the blood loss was minimal, without transfusion being necessary.The abdominal drain was removed in 24 hours and the patient was discharged in the second postoperative day. Compared to the classic approach by laparotomy, this method was less traumatic, required a shorter hospital stay, and followed by faster recovery.

Carcinoma de pequenas células do esôfago

Small cell carcinoma of the esophagus is a rare tumor described to the first time by Mckeown in 1952. Clinically it is very similar to small cell carcinoma of the lung. with quick evolution and early dissemination.It is more frequent in men between 60 and 70 years of age. The patients usually have dysphagia and weight loss. Most of the tumours arise in the middle and distal third of the esophagus. Chronic alcohol and tobacco use are usually present. The manegement of primary small cell cancer of the esophagus remains controversial with groups reporting treatment based on operation alone, local radiotherapy, chemotherapyalone, or operation with adjuvant therapy. Overall survivel remains poor at a mean of 5.1 months, with the best rate of survivel in patients undergoing operation with adjuvant chemotherapy. The authors relate two cases of a small cell carcinoma of the esophagus. Both of these patients was female and white, with 51 and 64 years old. The first mainestation was dysphagia and weight loss. Histologic study from endoscopic biopsies reveled the diagnosis. The treatment was, in the both cases surgery, however in one case, chemotherapy and mediastinal irradiation was associated to the ressection. The authors comment the more important aspects about this pathology and the treatment and survival of the patients.

Papiloduodenectomia como alternativa terapêutica para tumores papilares

The papiloduodenectomy is a procedure that, although accomplished rarely, has its validity in selected cases of papillary tumors. It is included in this group the patients with important diseases that doesn't have conditions of supporting the surgery of Whipple, the standard procedure for these pathologies. The authors review its experience with four patient carriers of malign neoplasia of the duodenal papila submitted to papiloduodenectomy. All the patients came jaundiced to the admission. The age varied of 62 to 82 years. The ultrassonography, the computed tomography and the endoscopy with biopsy were used for diagnosis and staging, and all the patients presented with initial stages (TI or T2). Two patients were classified as ASA3 and the other two as ASA4, according to the American Society of Anesthesiology. All the diagnoses were proven by the pathological exam of the surgical piece. It is ended that this procedure facilitates to obtain appropriate margins and satisfactory results when indicated of appropriate way.

Adenocarcinoma primário de duodeno

Primary adenocarcinoma of the duodenum is an extremely rare disease, and represents only 0.35 % of all gastrointestinal malignies. Early detection of the disease is dificult because doesn't have pathognomonic simptoms. The Whipple procedure is the optimal method of treatment. The authors relate one case of a adenocarcinoma of the duodenum in a 65- year-old white female with a history of abdominal pain for a six-month period, associated with postprandial fullness, vomiting and weight loss. Endoscopy showed a elevated tumor in the second part of the duodenum, with partial obstruction of the lumen. Histological study of endoscopic biopsies reveled a moderare differentiated adenocarcinoma of the duodenum. The treatment was surgical. The authors comment on the more important aspects of this pathology.

Pseudotumor de pâncreas por corpo estranho

The diagnosis of pancreatic masses represents a great challenger for imaging studies. However the occurrence of pancreatic masses have been reported more frequently in the last years due to advances in imaging diagnostic methods. During the last decade, the surgical approach of pancreatic masses was limited to an attempt of establishing histological diagnosis, staging and evaluation of resection of these masses. Recently, the approach and staging of pancreatic masses was facilitated by sophisticated methods of diagnosis, especially, ultrasound, dynamic computerized tomography, magnetic resonance imaging (/RM), angiography, endoscopic retrograde cholangiopancreatography (CPRE), endoscopic ultrasound, laparoscopy and biochemical tumors markers. The present paper reports a case of a pancreatic mass due to foreign body in which the imaging study helped to determine out this rare etiological agent that has not been previouly described in literature.

Leiomioma do esôfago removido por videolaparoscopia

This report describes a leiomyoma of the inferior third section of the esophagus removed during laparoscopic cholecystectomy. The patient is a woman 55-years-age, carrying esophageal myoma of 40 mm in diameter wide, situated in the posterior wall of the lower esophagus. Indications for surgery were based mainly on the growth of the mass (6 mm when discovered 7 years previously, increased to 40 mm). Recently the patient returned suffering from pain, which could be attributed to his litiasic cholecystopaty. A small degree of low disphagia could also be observed. Radiologic imaging, direct endoscopic examination and endoscopic ultrasound showed that the mioma protruded on to the oesophagic lumen, discreetly diminishing there. A laparoscopic esophageal myomectomy was indicated at the same session of the laparoscopic cholecystectomy. Once the pneunoperitoneum was installed, five ports were placed as if for a hiatus hernia surgery. The cholecystectomy was uneventful. Next, an esophagoscopy was performed so as to determine the precise area covering the base of the tumour; at the right-lateral site. Longitudinal and circular fibres of the esophagus was severed over the lesion and the enucleation of the tumour was performed alternating the monopolar dissection, bipolar and hidrodisection. Control-endoscopy was carried out to verify mucosa integrity. Four suture points with poliglactine 3-0 string so as to close the musculature followed this. One suture was placed in for diminution of the size of the esophagean hiatus. Total time of intervention: two hours (30m for the cholecystectomy and one hour and thirty minutes for the myomectomy). Postoperative period: uneventful. Disappearance of the disphagia was observed. Radiologic transit control with water-soluble contrast at 4th post-operative day: good passage. Diagnosis from laboratory of pathology: conjunctive tumour formed by muscle non-striated cells: leiomyoma. The patient was re-examined on the two-month postoperative follow-up. General conditions were good and there were no complain of dysphagia. Neither there were any symptoms of gastro-esophageal reflux.
