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.

Adenoma viloso da ampola de Vater

The aim of this paper is to present a case of a 37-year-old female patient with a benign tumor of the Ampulla of Vater and a brief review of the literature. The patient presented with progressive obstructive jaundice and weigth loss due to the presence of two adenomas of the second portion of duodenum. Laboratory tests confirmed the presence of obstruction of the biliary tree. Ultrasound and CT scan of the abdomen revealed bile duct dilatation. ERCP showed a tumor at the site of the Ampulla of Vater. The biopsies revealed tubular adenoma. She was submitted to local resection of the tumors and sphincteroplasty, since the frozen biopsy at the time of surgery showed no malignancy. During the post-operative follow-up she presented recurrence of symptoms. An upper GI endoscopy revealed a tumor at the Ampulla of Vater. She was then submitted to Whipple procedure with an uneventful recovery.

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.

Fístula pieloduodenal espontânea

Authors present two cases of spontaneous pyeloduodenal fistulas associated to suppurative kidney disease. In both cases the fistulas developed from pyonephrosis and perirenal abscesso Diagnosis was made through intravenous or retrograde pyelogram and two patients were successfully treated by nephrectomy and primary duodenorraphy. Authors present a literature review concluding that 72 additional cases of pyeloduodenal fistulas have been described.

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.

Estenose esofagiana congênita por coristoma

Oesophageal choristomas are a very uncommon cause of congenital oesophageal stenosis. A high index of suspection is necessary for differential diagnosis with commoner causes of oesophageal suboclusion in childhood, mainly acquired oesophageal obstruction caused by gastroesophageal reflux. We present a case report and review the clinical, endoscopic and radiologic features of the disease and consider the need for padronization of surgical techniques to treat this condition, which is still controversial.

Adenomioma da papila de vater em adulto jovem

The authors report a case of adenomyoma of papilla of Vater in a young adult, a rare pathology in this age and site. The commonest clinical findings are abdominal pain, dyspepsia and jaundice, as in this case in which the patient referred these symptoms for several months. The diagnosis is usually difficult before surgery, because the radiological and endoscopic appearances are difficult to interpret, since they may only show obstruction and enlargement of the biliary tract; in this way, the endoscopic biopsy may be useful. In the present case the computed tomography, abdominal scan and intraoperative cholangiography only demonstrated obstruction and enlargement of the biliary tract, without the presence of gallstones. The treatment is usually lesion resection according to its size, performing the total resection in those cases of extensive involvement of the digestive tract, as it was performed in this case, due to the dimension of the lesion and its malignant appearance. The patient was discharged from hospital on the thirteenth postoperative day, with a histological diagnosis of adenomyoma of papilla of Vater. Three months after the procedure the patient was asymptomatic.

Anomalia da via biliar extra-hepática

We show an anatomical modification of extrahepatic biliary ducts in a fifty-eight years old female who presented right hipocondric pain, jaundice and fever two months after cholecystectomy. The patient underwent ERCP wich showed an anatomical modification that consists in an union of the right and left hepatic ducts, with insertion into the cystic duct, right hepatic duct, being a choledochus agenesis.

Migração de clipe metálico para úlcera duodenal após colecistectomia videolaparoscópica: Ligaclip migration into a duodenal ulcer following laparoscopic cholecystectomy

We report a rare cause of pyloric stenosis caused by migration of surgical clips into a duodenal ulcer following laparoscopic cholecystectomy. Even after endoscopic removal of the clips the inflammatory reaction during the healing process caused a stenosis of the pylorus that eventually required a truncal vagotomy and gastroenterostomy.

Extração de fitobezoar gástrico por videolaparoscopia: considerações técnicas originais

Videolaparoscopic surgery has been used for treatment of almost all surgical abdominal diseases, mainly where there are no large ressections, or operative field is limited. In these situations, laparoscopic surgery has the advantages of less morbidity, quick recovery and good cosmetic results. Bezoars removal, or its mobilization, is probably included in these possible proceedings. Three non-laparotomic procedures were described: 1. endoscopic-laparoscopic; 2. videolaparoscopy and mobilization of intestinal bezoar to the cecum; 3. laparoscopy and gastrotomy for bezoar removal, through suprapubic incision or the umbilical punction. There have been only two publications describing the videolaparoscopic method for bezoar removal, and the methods applied can be complications or morbidity related. We describe one case where the applied technique is simple and easy to perform, time saving and probably less complications-related. This technique, with four trocars, utilized a plastic bag besides the stomach to be opened, followed by gastrotomy, bezoar removal and immediate introduction in the plastic bag, suture of gastrotomy and removal through the left subcostal trocar. This technique was feasible and easy to perform, with short operative time, and there were no intra or post-operative complications; the patient was discharged in the second post-operative day, and is without further problems after one year follow-up. We believe that this could be an adequate technique to perform laparoscopic gastric bezoar removal, and the rigid sequence of operative events allows a quick procedure, with minimal contamination. The videolaparoscopy seems to be an adequate access to surgical treatment of gastro-intestinal bezoars, with or without obstruction, and should be the ellected the procedure of choice to begin the surgical treatment, with convertion to laparotomy in case of any intra-operative adversity.

Drenagem endoscópica de abscesso pancreático

Surgical drainage is still considered the gold standard treatment of pancreatic abscess. Patients with high surgical risk, however, require alternative therapy. The authors report three cases of pancreatic abscess that were treated endoscopically. In patients who met endoscopic drainage criteria, treatment was effective, though one case did require surgical intervention as a result of gastric puncture point bleeding. After this initial experience, we believe that endoscopic drainage should be considered in selected cases.

Nova técnica de alimentação enteral em fístulas esôfago-jejunais

BACKGROUND: A new procedure for the treatment of esophageal fistula, mainly associated to the ebb esophagojejunal in patients submitted to the total gastrectomy and reconstruction with loop jejunal Rouxen-Y anastomosis is present. METHODS: The method is based in the use of "probe standard enteral prolongated with drain to laminate adapted in extremity", which results in advanced positioning inside the jejunum, making the administration of enteral nutrition possible and impeding ebb esophagojejunal. RESULTS: The authors discuss the theoretical advantages of the procedure and they suggest that the treatment of esofagic fistula with probe prolonged enteral would be suitable in the treatment of the fistula esophagojejunal by preventing the ebb esophagojejunal, which would result in smaller period of duration of the fistula esophagojejunal and it would prevent the high mortality rate. CONCLUSIONS: Preliminary studies demonstrated that this is a technically easy, low cost procedure through the endoscopic use. A prospective evaluation for morbility and mortality related to the method is needed.

Simpatectomia lombar retroperitoneal endoscópica

In the last few years, there has been an increase in the indication of lumbar sympathectomy for plantar hyperhidroses. There are few reports of the laparoscopic access for this operation, even when it seems to be a very apropriate method. A case of a left lumbar sympathectomy through the retroperitoneal endoscopic approach is presented. The total control of left plantar hiperhidroses was achieved, showing the effectiveness of this operation, completely feasible through extraperitoneal endoscopic route.
