Transgastric drainage for subdiaphragmatic abscess secondary to perforation of the sigmoid colon after cytoreductive surgery for advanced ovarian cancer.

Drainage of subdiaphragmatic abscesses is difficult due to its anatomical location and it can result in adverse events, including organ damage and the spread of infection. In recent years, endoscopic ultrasonography (EUS) guided drainage for upper abdominal abscesses has become available. We report a case of successful infection control using this procedure for a subdiaphragmatic cyst secondary to perforation of the sigmoid colon after cytoreductive surgery for advanced ovarian cancer. A Japanese woman in her 60s underwent laparotomy for ovarian cancer, and then developed sigmoid colon perforation 6 days after surgery. The emergency reoperation was performed, and a cyst suspected to be an antibiotic-resistant fungal abscess appeared under the left diaphragm in the postoperative period. We adopted an EUS-guided route for diagnostic and therapeutic drainage method, which enabled shrinkage of the cyst and did not concur further adverse events. This procedure was effective as a minimally invasive drainage route for subdiaphragmatic cysts.

[A case of subphrenic abscess in a very elderly patient relieved by conservative treatment].

A patient in her 90s with rheumatoid arthritis was admitted to the hospital. She was brought to the emergency department with a complaint of a fever and diagnosed with a urinary tract infection on admission, and antimicrobial therapy was started. On day 8 of admission, abdominal ultrasonography revealed a right subphrenic abscess due to cholecystitis with perforation. The patient consulted with the Department of Surgery, but drainage was deemed difficult due to the anatomical location of the gallbladder, and conservative treatment with antibiotics was continued. After two months of intravenous antimicrobial therapy, the abscess shrank, and the patient was discharged from the hospital after switching to oral antimicrobial therapy. At a follow-up visit two weeks after discharge, the abscess was confirmed to have disappeared, the oral antimicrobial therapy was discontinued, with no abscess recurrence noted. The principle of treatment for subphrenic abscess is the administration of broad-spectrum antimicrobial agents that cover enterobacteria and anaerobes, and drainage at appropriate times. Indeed, drainage is performed in most of the reported cases of subphrenic abscesses. However, in very elderly patients or those in whom puncture is difficult, conservative treatment while carefully checking imaging findings and other potentially involved factors may be an option.

Subdiaphragmatic abscess due to penetration of a duodenal ulcer successfully treated with endoscopic transgastric drainage: a case report.

BACKGROUND: Subdiaphragmatic abscesses are sometimes caused by intraabdominal infections. We report a case of endoscopic ultrasound-guided transgastric drainage. CASE PRESENTATION: A 75-year-old Asian man was referred to our hospital for treatment for upper gastrointestinal bleeding. On admission, blood tests showed a marked inflammatory response, and abdominal computed tomography showed free air in the abdominal cavity and a left subdiaphragmatic abscess. Therefore, the patient was diagnosed with an intraabdominal abscess associated with a perforated duodenal ulcer. Because he did not have generalized peritonitis, fasting and antibiotic treatment were the first therapies. However, because of the strong pressure on the stomach associated with the abscess and difficulty eating, we performed endoscopic ultrasound-guided transgastric drainage. After treatment, the inflammatory response resolved, and food intake was possible. The patient's condition remains stable. CONCLUSIONS: Drainage is the basic treatment for subdiaphragmatic abscesses; however, percutaneous drainage is often anatomically difficult, and surgical drainage is common. We suggest that our success with endoscopic ultrasound-guided transgastric drainage in this patient indicates that this approach can be considered in similar cases and that it can be selected as a minimally invasive treatment method.

Acute Phlegmonous Gastritis Complicated by Subphrenic Abscess.

BACKGROUND: Phlegmonous gastritis (PG) is a rare and potentially fatal disease characterized by bacterial infection of the gastric wall. However, its clinical features are nonspecific, which may delay its diagnosis and treatment. CASE REPORT: We report a case of a previously healthy 53-year-old woman with localized PG complicated by subphrenic abscess formation who was treated successfully with antibiotics and percutaneous catheter drainage. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early diagnosis and treatment initiation are important to improving outcomes. Emergency physicians should consider PG a differential diagnosis of acute abdomen.

Neoplasia fusocelular - tumor de gist: presentación de un caso / Fusocellular neoplasia - gist tumor: presentation of a case

Los tumores del estroma gastrointestinal (TEGI) son las neoplasias mesenquimales más frecuentes del tracto digestivo con una frecuencia de 0,1 a 3 % de todas las neoplasias gastrointestinales. Son derivadas de las células intersticiales de Cajal, localizadas a lo largo del plexo mioentérico de la pared intestinal. Comprenden leiomisarcomas, leiomioblastomas, leimiomas, schwannomas. Están formadas por células fusiformes, en la mayoría, epitelioides o ambas. Se localizan predominantemente en estómago e intestino delgado. Inmunohistoquimicamente se detecta expresión de receptores KIT (antígeno CD117) que puede ser focal, variable o difusa. Involucran tumores benignos pero con potencial malignidad hasta sarcomas metastizantes. Su pronóstico se basa el tamaño y porcentaje de mitosis. La sintomatología depende del lugar de origen, en este caso como masa palpable abdominal y obstrucción intestinal. El tratamiento es la resección completa con márgenes limpios. En caso de metástasis preoperatoria, esta no cambia la conducta quirúrgica, debido a la posibilidad de obstrucción y sangrado. El Imatinib a dosis de 400 mg controla el crecimiento eventual de enfermedad residual. Se presenta el caso clínico de paciente con masa abdominal y cuadro de obstrucción intestinal que evoluciona a la perforación de un TEGI localizado en yeyuno proximal con cuadro peritoneal y absceso subfrenico. Se procede a resección intestinal con yeyuno yeyuno anastomosis resección completa. La histopatología reporta Tumor estronal gastrointestinal y la inmunohistoquimica Neoplasia Fusocelular. CONCLUSION: Los TEGI son de origen mesenquimal, comprenden espectro grande de tumores desde benignos, hasta carcomas altamente malignos. Los factores pronósticos se asocian al tamaño e índice mitótico del tumor. La inmunohistoquimica reporta su expresión para CD117. La resección quirúrgica completa es el pilar de tratamiento y en casos de resección incompleta o irresecabilidad puede usarse imatinib.

Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal neoplasms of the digestive tract with a frequency of 0.1 to 3% of all gastrointestinal neoplasms. They are derived from the interstitial cells of Cajal, located along the myoenteric plexus of the intestinal wall. They include leiomysarcomas, leiomioblastomas, leimiomas, schwannomas. They are made up of spindle cells, in the majority, epithelioids or both. They are located predominantly in the stomach and small intestine. Immunohistochemically, KIT receptor expression (CD117 antigen) is detected, and they can be focal, variable or diffuse. They involve benign but potentially malignancy tumors up to metastatic sarcomas. Their prognosis is based on the size and percentage of mitosis. The symptoms depend on the place of its origin. Treatment is complete resection with clean margins. In the case of preoperative metastases, this does not change the surgical approach, due to the possibility of obstruction and bleeding. Imatinib at a dose of 400 mg controls the eventual growth of residual disease. We present the clinical case of a patient with an abdominal mass and a small bowel obstruction that progresses to perforation of a GIST located in the proximal jejunum with a peritonitis and subphrenic abscess. Intestinal resection is performed with jejunum jejunoanastomosis and complete resection. Histopathology reports gastrointestinal stromal tumor and immunohistochemistry, Fusocellular neoplasia. Conclusion: GIST are of mesenchymal origin, they include a wide spectrum of tumors from benign to highly malignant sarcomas. Prognostic factors are associated with tumor size and mitotic index. Immunohistochemistry reports its expression for CD117. Complete surgical resection is the mainstay of treatment and in cases of incomplete resection or unresectability imatinib can be used.

An Unexpected Case of Perforated Acalculous Cholecystitis Caused by a Fish Bone.

Gallbladder inflammation is most often determined by the presence of gallstones. Acalculous cholecystitis usually occurs in patients with multiple comorbidities or with an immunosuppressed status, and therefore its evolution is faster and more severe compared to acute calculous cholecystitis. The presence of a fish bone into the peritoneal cavity, through a gastrointestinal fistula is not very rare, but acute cholecystitis caused by a fish bone is unexpected. Here, we present the case of a 75-year old woman who had eaten fish two months before and presented at the Emergency Room with perforated acalculous cholecystitis and a right subphrenic abscess. The laparoscopic approach permitted the evacuation of the subphrenic abscess, bipolar cholecystectomy and removal of a fish bone from nearby the cystic duct. Postoperative evolution was uneventful, with hospital discharge after five days. The patient was in good clinical condition at two months follow-up.

Drainage of a Subphrenic Abscess Followed by Two-Stage Gastrectomy and Adjuvant Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for Perforated Gastric Carcinoma: A Case Report.

BACKGROUND Perforated gastric cancer accounts for less than 1% of patients who present with an acute abdomen and for up to 16% of all gastric perforations. A two-stage laparoscopic procedure may be the therapeutic strategy of choice in selected patients, and adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) can reduce the incidence of peritoneal recurrence. A rare case of subphrenic abscess and gastric perforation due to carcinoma of the gastric fundus, followed by two-stage gastrectomy and adjuvant HIPEC is presented. CASE REPORT A 65-year old man presented with a left subphrenic abscess secondary to perforated gastric carcinoma. Laparoscopic drainage of the abscess was performed. Ten days later, following recovery from sepsis, the patient underwent total laparoscopic gastrectomy, and adjuvant HIPEC followed by a Roux-en-Y esophagojejunostomy. Histopathology showed an intestinal-type gastric adenocarcinoma. The tumor was staged as pT4aN0. The postoperative course was uneventful except for transient atrial fibrillation. The patient was discharged home on postoperative day 11. Systemic adjuvant chemotherapy was begun one month later. At six-month follow-up, the patient had no discomfort on eating or any other symptoms. CONCLUSIONS In this case, a two-stage laparoscopic treatment for perforated gastric carcinoma combined with adjuvant HIPEC was feasible and safe and may be considered at the time of laparoscopic gastrectomy in selected patients with perforated gastric carcinoma.

Endoscopic ultrasound-guided transmural drainage for subphrenic abscess: report of two cases and a literature review.

BACKGROUND: An intra-abdominal abscess can sometimes become serious and difficult to treat. The current standard treatment strategy for intra-abdominal abscess is percutaneous imaging-guided drainage. However, in cases of subphrenic abscess, it is important to avoid passing the drainage route through the thoracic cavity, as this can lead to respiratory complications. The spread of intervention techniques involving endoscopic ultrasonography (EUS) has made it possible to perform drainage via the transmural route. CASE PRESENTATION: We describe two cases of subphrenic abscess that occurred after intra-abdominal surgery. Both were treated successfully by EUS-guided transmural drainage (EUS-TD) without severe complications. Our experience of these cases and a review of the literature suggest that the drainage catheters should be placed both internally and externally together into the abscess cavity. In previous cases there were no adverse events except for one case of mediastinitis and pneumothorax resulting from transesophageal drainage. Therefore, we consider that the transesophageal route should be avoided if possible. CONCLUSIONS: Although further studies are necessary, our present two cases and a literature review suggest that EUS-TD is feasible and effective for subphrenic abscess, and not inferior to other treatments. We anticipate that this report will be of help to physicians when considering the drainage procedure for this condition. As there have been no comparative studies to date, a prospective study involving a large number of patients will be necessary to determine the therapeutic options for such cases.

Proteus mirabilis harboring carbapenemase NDM-5 and ESBL VEB-6 detected in Austria.

We describe a case of carbapenemase-harboring Proteus mirabilis together with detection of NDM-5 in Austria accompanied by other bacterial strains with a wide range of beta-lactamases including OXA-181 and VEB-6. Isolates were obtained from a subphrenic abscess from one patient who was previously treated with broad-spectrum antibiotics in Bangladesh.

Temporal Trends in the Uptake and Continuation of the Etonogestrel Implant in a Large Private Practice Setting.

OBJECTIVE: To assess temporal trends in the uptake and continuation of the etonogestrel subdermal implant in a large private practice setting. METHODS: This was a retrospective cohort study based on billing records from a large multispecialty private practice in Las Vegas, Nevada. We looked at women of all ages seeking long-acting reversible contraception (LARC) between January 1, 2013, and December 31, 2016. The main outcome measure was uptake of the etonogestrel subdermal implant, expressed as a fraction of all insertions of LARC across four calendar years (2013-2016). The Kaplan-Meier method was used to estimate 12-month continuation stratified by year of insertion. RESULTS: There were 3477 total LARC insertions across the 4-year study period. In unadjusted analyses, the uptake of the etonogestrel implant increased from 3.0% of LARC insertions in 2013 to 9% in 2016 among women aged 30 years and older. For women younger than 30 years, the uptake of the implant stayed stable from 2013 to 2015 (22.8%, 21.7%, and 22.4%, respectively), but increased to 30.9% in 2016. We modeled the uptake of the implant as a function of year of insertion adjusted for age (continuous) and insurance status (private vs. Medicaid), and we stratified the models by age (younger than 30 years, 30 years, and older than 30 years). The positive association between year of insertion and uptake of the implant was significantly stronger for women aged 30 years and older, compared to women younger than 30 years. There was a progressive decrease in the 12-month continuation of implant from 2013 (95.7%) to 2015 (57.7%). CONCLUSIONS: In this large private practice setting, among women aged 30 years and older, we observed a threefold increase in the uptake of the subdermal implant from 2013 to 2016. We also observed a significant decrease in the 12-month continuation of the implant over time. Further studies of implant uptake and continuation in the private practice setting are needed.

[A CASE OF SUBPHRENIC ABSCESS WITH PARADOXICAL RESPONSE CAUSED BY MYCOBACTERIUM TUBERCULOSIS].

A 40-year-old woman was admitted to our hos- pital with cough and sputum production. A chest computed tomography (CT) scan revealed a diffuse nodular shadow in the upper lung. The patient was diagnosed with pulmonary tuberculosis, based on a positive T-SPOT®.TB test result of peripheral blood and a positive polymerase chain reaction (PCR) test result for Mycobacterium tuberculosis in gastric aspirates. M.tuberculosis was subsequently isolated from the gastric aspirate specimen. After 2 months of treatment with antituberculous medication, the patient developed a low grade fever and left-sided chest pain. A CT scan revealed a left pleural effusion and a right subphrenic abscess. Tuber- culous pleurisy with paradoxical response was diagnosed on the basis of an increased lymphocyte count and increased adenosine deaminase activity in the pleural fluid exudate. A percutaneous ultrasound-guided needle biopsy of the sub- phrenic abscess was performed. Histological analysis revealed epithelioid cell granulomas with necrosis and PCR for M. tuberculosis using puncture needle washing fluid returned positive results. Based on these findings, a diagnosis of subphrenic abscess with paradoxical response, caused by M. tuberculosis, was made. Subphrenic abscess caused by M. tuberculosis is an important consideration during antituber- culous therapy.

A case of left subphrenic abscess caused by gastric ulcer penetration that was successfully treated with endoscopic transgastric drainage.

A 65-year-old male visited our hospital because of fever and difficulty in walking. He was suffering from left-sided hypochondrial pain for a month. Laboratory tests performed on admission revealed a white blood cell count of 1700/µl and C-reactive protein level of 9.51mg/dl, which were suggestive of severe inflammation. Contrast-enhanced computed tomography revealed a subphrenic abscess around the spleen, which we considered to be caused by gastric penetration into the gastrosplenic ligament. Upper esophagogastroduodenoscopy revealed a gastric ulcer together with a fistula that connected to the left subphrenic abscess. We thus performed endoscopic transgastric drainage through the fistula. Antibiotics and a proton pump inhibitor were administered, and drainage was continued. The patient's clinical and inflammatory symptoms subsequently improved. We thus consider that endoscopic transgastric drainage is an appropriate treatment option for subphrenic abscesses.

The use of surgical drains in laparoscopic splenectomies Consideration on a large series of 117 consecutive cases.

BACKGROUND DATA: The use of surgical drains after traditional splenectomy has been largely debated and several Authors have been unfavorable to their use. With the advent of laparoscopic splenectomy, their role has been re-discussed. The increased risk of undetectable pancreatic, gastric or colon injury in challenging laparoscopic removal of the spleen have induced some surgeons to reconsider the advantages related to their use. METHODS: One hundred seventeen consecutive cases of laparoscopic splenectomy with routine use of surgical drains have been reviewed. Indications for surgery, length of operations, post-operative day of drain removal, post-operative complications were retrospectively analyzed. RESULTS: Laparoscopic splenectomy was performed for idiopathic thrombocytopenic purpura in 77 patients (65,8%), splenic lymphoma in 11 (9,4%), hereditary spherocytosis in 12 (10,2%), ß-thalassemia in 6 (5.1%), other diseases in 11 (9,4%) cases. Conversion to open surgery was necessary in 11,1% of cases. Drains were removed 2-3 days after surgery in 95,8%, within 10 days in 3.4%, within 2 months in 0,8% of cases. In 2 cases a post-operative bleeding, detected through the drainage, required re-operation. One patient with myelofibrosis and massive splenomegaly developed a late post-operative subphrenic abscess, successfully treated by a percutaneous drainage. CONCLUSIONS: In Authors' experience, the use of drains after laparoscopic splenectomy helped detect early post-operative bleeding. Surgical drains could reduce the incidence of fluid intra-abdominal collections and infections. Their use should be recommended in the laparoscopic approach, especially in technically demanding surgical procedures. KEY WORDS: Laparoscopy, Surgical drainage, Splenectomy.

[Perforation of the right ventricle of the heart as a complication of CT guided percutaneous drainage of a subphrenic abscess - a case report]. / Perforace pravé srdecní komory jako komplikace CT navigované perkutánní drenáze subfrenického abscesu kazuistika.

INTRODUCTION: CT guided percutaneous drainage is currently the gold standard in the treatment of abdominal fluid collections, having substituted open surgical drainage in many cases. It burdens the patient less than surgical drainage. Its efficiency is comparable to standard surgical drainage when properly indicated. It is readily available even in smaller hospitals. However, this method can also have many complications, which originate most often from an improperly targeted drainage catheter. CASE REPORT: The authors describe a case report of a 55 years old man with a right-sided subphrenic abscess. The right ventricle of the heart was perforated during a CT guided percutaneous drainage. The bleeding was minimal, but the patient suffered a profound septic shock as a result of massive bacteremia during direct communication of the contents of the abscess cavity with blood circulation. He was operated immediately. The right ventricle was sutured, and the subphrenic abscess was drained. There were no complications after the operation, and the patient was discharged on day 17 after the surgery. CONCLUSION: The CT guided drainage of an abdominal abscess or a fluid collection in a risk area should be preferably done in hospitals whose therapeutic portfolio also includes the handling of serious complications. KEY WORDS: heart injury drainage.

Retroperitoneal abscess with retained gall-stones as a late complication of laparoscopic cholecystectomy.

Laparoscopic cholecystectomy is the golden standard, considering treatment of cholelithiasis. During the laparoscopic procedure one may often observe damage to the gall-bladder wall, as well as presence of gall-stones in the peritoneal cavity, as compared to classical surgery. These gall-stones may be associated with the occurrence of various complications following surgery. The study presented a rare case of a retroperitoneal abscess, as a consequence of retained gall-stones, in a female patient who was subject to laparoscopic cholecystectomy two years earlier.

Nodular histiocytic/mesothelial hyperplasia as consequence of chronic mesothelium irritation by subphrenic abscess.

PURPOSE: Pleural nodular histiocytic/mesothelial hyperplasia is a nodular histiocytic/mesothelial proliferation, often delimiting cystic cavities, due to irritation by a pulmonary noxa. Case report results: The patient had right pleural parietal and diaphragmatic thickness, with pleural effusion, without lung alterations. He previously underwent left hemicolectomy and liver resection, due to a diverticulitis and a liver histiocytes-rich abscess. Video-assisted thoracoscopy biopsy showed a double population of reactive mesothelial cells and histiocytes. CONCLUSION: Nodular histiocytic/mesothelial hyperplasia represents a potential pitfall for pathologists. Immunohistochemistry is crucial for the differential diagnosis with some malignancies. We suggest that in our patient, a chronic mesothelium inflammation happened by transdiaphragmatic involvement as a consequence of the liver abscess. Some pathogenetic mechanisms are hypothesized.
