Apendicite em hérnia femoral com formação de fístula estercoral

The presentation of acute appendicitis in femoral hernia is rare. The gastrointestinal symptons are overshadowed by the local findings. This may lead to delayed diagnosis and complications such as formation of fistula. The authors report a case of a 76-year-old female patient which presented with stercoral fistula after drainage of a right groin abscess ten months earlier.

Tuberculose hepática pseudotumoral

Tuberculous involvement of the liver is usually a diffuse process, associated with miliary tuberculosis. However localized tuberculosis of the liver producing a macronodular tuberculoma or an abscess is rare. The authors present a case of pseudotumoral hepatic tuberculosis in a 34-year old woman. This patient presented a 2 month history of fever weight loss of 4Kg and right upper quadrant abdominal pain. She denied jaundice, choluria, or acholia. Laboratory investigation, including renal and liver function tests. revealed normal levels. Chest X-ray was normal. Abdominal ultrasonography demonstrated a hypoechoic nodule in the right hepatic lobe. CT scan showed hypodense areas in the same place and no retroperitoneal lymphadenopathy. Due to the inespecificity of the signs, symptoms and image findings, a diagnostic laparoscopy was performed, it was however inconclusive. Then, the patient was submitted to a laparotomy with ressection of the lesion. Histological examination revealed a tuberculoid granulomatous lesion with caseous necrosis. Postoperatively, the patient was placed on antituberculous chemotherapy with rifampin, isoniazid and pyrazinamide. Eight months later the patient is asymptomatic.

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.

Abscesso hepático piogênico associado à esquistossomose mansônica

The authors report a case of the 15 year old young man, from endemic zone of schistosomiasis and with a chronic schistosomiasis, was admitted complaining of continuous pain in the right upper quadrant, spreaded to epigastrium and right lower quadrant which, began 10 days before. It was associated to fever, anorexia, hepatomegaly, esplenomegaly and signs of peritoneal irritation without clinical improvement. At laparotomy multiple liver microabscesses were found. Excluded the classic etiology, a liver biopsy was done and showed Schistossoma mansoni eggs. surrounded by the same inflamatory cells of microabscesses. This suggested that they have been the predisposing cause for the formation of liver abscesses, as shown in the literature. Schistosomiasis can be complicated with pylephlebitis, immunodepression and granulomatous reaction, centrallobular necrosis and a raise in the infection risk. The described data suggest the schistosomiasis as the etiology of hepatic microabscesses, mainly in endemic zones.

Peritonite por bário

We report a case of a 49 years-old man who underwent a barium meal examination for an epigastric pain. A perforated gastric ulcer with barium extravasation into peritoneal cavity was seen on X-rays. During an emergency laparotomy, a perforated pyloric ulcer was noted, along with barium contamination in the peritoneal cavity. The ulcer was closed with an omental patch and an extensive peritoneal lavage with saline was performed. During the postoperative period, the patient developed signs of peritonitis and underwent a new laparotomy was at the 9th day showing a subfrenic abscess with a large barium contamination. The patient presented septic shock and multiple organ failure. dying on the 21th day.

Abscesso esplênico

Splenic abscess is a rare disease usually associated with immunosuppressed states. Its diagnosis may be difficult due to non-specific symptoms . The authors report a case of a healthy woman, 42 years old, bearer of splenic and renal abscesses , treated with antibiotics and splenectomy. A review of the literature is presented with emphasis on the diagnosis and treatment.

Abscesso hepático piogênico por corpo estranho

Pyogenic hepatic abscess by a foreign body is a rare disease and its diagnosis is habitually made during necropsy. The authors present a case of a woman operated because of a pyogenic hepatic abscess, in the interior of which bristle made of material of vegetable origin were encountered and identified in the laboratory as the principal rib of a leaf, known in Brazil as piaçava. The hepatic abscess was drained and the patient was discharged. The probable mechanism for the formation of the hepatic abscess consisted of the accidental ingestion, perforation of the intestines and penetration in the liver.

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.

Abscesso intrabdominal tardio pós colecistectomia laparoscópica

Perforation of the gallbladder during laparoscopic cholecystectomy may be associated with intraperitoneal gallstone spillage. Several complications secondary to lost gallstones in the abdominal cavity have been described. We report a rare complication of abdominal abscess secondary to two gallstones left in the abdominal cavity. A 75-year-old female presented with spontaneous drainage of pus through the umbilicus five years after laparoscopic cholecystectomy. An ultrasonographic evaluation of the abdomen revealed a solid mass of 56x26 mm of diameter, with acoustic shadow, localized distal to the umbilicus. At laparotomy, an abscess with two biliary calculi was drained. The patient had good recovery, with no complication.

Oclusão intestinal por compressas cirúrgicas intraluminais: experiência de cinco casos

Despite being unusual, retained foreign bodies after surgical procedures is a matter of great concern for surgeons. The main purpose of this article is to describe five cases of intestinal obstruction due to intraluminal surgical sponges. The average time between the first operation and the intestinal obstruction was eight months. All patients referred abdominal pain and change of intestinal habit prior to the intestinal obstruction. In two cases bowel perforation was also observed, in addition to the intestinal obstruction. Four patients had no postoperative complications. One patient died due to an intra-abdominal abscess and sepsis.

Utilização da jejunostomia para extração endoscópica de Ascaris lumbricoides da via biliar principal em paciente com doença de Caroli

Grumbach-Auvert disease represents a type of Obstructive Disease of the Intrahepatic Biliary Tree. We presents a case report of a patient with hepatic abscess caused by Ascaris which ascended into hepatic parenquima through hepaticojejunostomy, resolved by endoscopic extraction of it after the jejunostomy of permanent access was opened.

Complicated diverticular disease: the changing paradigm for treatment

The term "complicated" diverticulitis is reserved for inflamed diverticular disease complicated by bleeding, abscess, peritonitis, fistula or bowel obstruction. Hemorrhage is best treated by angioembolization (interventional radiology). Treatment of infected diverticulitis has evolved enormously thanks to: 1) laparoscopic colonic resection followed or not (Hartmann's procedure) by restoration of intestinal continuity, 2) simple laparoscopic lavage (for peritonitis +/- resection). Diverticulitis (inflammation) may be treated with antibiotics alone, anti-inflammatory drugs, combined with bed rest and hygienic measures. Diverticular abscesses (Hinchey Grades I, II) may be initially treated by antibiotics alone and/or percutaneous drainage, depending on the size of the abscess. Generalized purulent peritonitis (Hinchey III) may be treated by the classic Hartmann procedure, or exteriorization of the perforation as a stoma, primary resection with or without anastomosis, with or without diversion, and last, simple laparoscopic lavage, usually even without drainage. Feculent peritonitis (Hinchey IV), a traditional indication for Hartmann's procedure, may also benefit from primary resection followed by anastomosis, with or without diversion, and even laparoscopic lavage. Acute obstruction (nearby inflammation, or adhesions, pseudotumoral formation, chronic strictures) and fistula are most often treated by resection, ideally laparoscopic. Minimal invasive therapeutic algorithms that, combined with less strict indications for radical surgery before a definite recurrence pattern is established, has definitely lead to fewer resections and/or stomas, reducing their attendant morbidity and mortality, improved post-interventional quality of life, and less costly therapeutic policies.

Comparison between electrocautery and fibrin selant after hepatectomy in rats

OBJECTIVE: To compare between electrocautery and fibrin sealant hemostasis in rats after partial hepatectomy.METHODS: we used 24 Wistar rats, which were submitted to 30% hepatic resection, divided into two groups of 12 animals each: Group Electrocautery and Group Tachosil(r). These animals were evaluated after three and 14 days. We assessed the presence of complications, laboratory tests and histological exam of the recovered liver.RESULTS: the presence of abscess was more prevalent in the electrocautery group. The observed adhesions were more pronounced in the electrocautery group, both in frequency and in intensity, after three and 14 days. There were no deaths in either group. As for laboratory analysis, after three days the hematocrit was lower in the TachoSil(r) Group. The elevation of AST and ALT were more pronounced in the electrocautery group (p = 0.002 and p = 0.004) in three days. Histological analysis of specimens collected on the third day after surgery showed similar results in both groups for the presence of polymorphonuclear cells, whereas mononuclear was more evident in the TachoSil(r) group. We also observed that angiogenesis, although present in both groups, was more pronounced in the TachoSil(r) group (p = 0.030). However, on the 14th day angiogenesis was more pronounced in the electrocautery group, but without statistical significance.CONCLUSION: hemostasis achieved by the groups was similar; however, the use of electrocautery was associated with infections, adhesions at higher grades and elevated liver enzymes.

Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis

OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years); 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

Closure of large wounds using rubber bands in rabbits

OBJECTIVE: to verify the effectiveness of the rubber elastic band in the treatment of large wounds of the body wall of rabbits by means of traction of its edges. METHODS: we studied 30 New Zealand rabbits, divided into three groups (n=10): Group 1- healing by secondary intention; Group 2- removal and eutopic repositioning of skin as full thickness skin graft; Group 3- Approximation of wound edges with elastic rubber band. In all animals, we removed a segment of the back skin and subcutaneous tissue down to the fascia, in accordance with an acrylic mold of 8cm long by 12cm wide. All animals were observed for 21 days. RESULTS: two animals of groups 1 and 2 had wound abscess. In Group 2, there was partial or total graft loss in 90% of animals. The complete closure of the wounds was observed in four animals of Group 1, six of Group 2 and eight of Group 3. There was no difference between the scar resistance values of groups 2 and 3, which were higher than those in Group 1. The scars of the three groups were characterized by the presence of mature connective tissue mixed with blood vessels and inflammatory infiltration, predominantly polymorphonuclear. CONCLUSION: the tensile strength of the wound edges with rubber elastic band is as efficient as the skin graft to treat rabbits' large body wounds.
