Demographic, Clinical, Laboratory and Management Profile in Patients of Amoebic Liver Abscess from Northern India

Background: Amoebic liver abscess (ALA) is a serious extra-intestinal manifestation of amoebiasis and a major problem in developing countries. Due to rapid urbanization, improved sanitation and hygiene in India, there has been a shift in disease epidemiology towards non-communicable disease, but recent changes in epidemiological and clinical pattern in ALA are not well studied. Aim: To evaluate recent demographic, clinical, laboratory and management profile in patient with ALA. Methods: It is a prospective observational study conducted in the Department of Gastroenterology, SMS medical college, Jaipur, Rajasthan from June 2018 to December 2020. A predesigned semi structured questionnaire consisting of socio-demographic factors, risk factors, clinical, laboratory and management profile was used to collect data. Result: A total 508 patients of amoebic liver abscess were analysed. Median age of presentation was 40 years, majority were males (90.4%) with chronic alcoholism (44.1%) and belonging to lower socio-economic class. Abdominal pain, fever and anorexia were the most common symptoms. A majority had right lobe involvement (77.6%) and solitary abscess in 67.5%. Most of the small liver abscesses (68%) were managed by medical treatment alone. Percutaneous needle aspiration was done in 62.6% patients, mostly for abscess size 5-10 cm (93%) with 90% success. A total of 24.6% patients underwent percutaneous catheter drainage, all successfully done. Intraperitoneal rupture was seen in 10% patient. Mortality was 1.5%. Conclusion: This is one of the largest cohorts of ALA which shows that a majority of cases are males from lower socioeconomic status with history of significant alcohol intake. Early initiation of a combined therapeutic approach leads to early symptomatic improvement, fewer complications and better outcomes.

Clinical features and management of amoebic liver abscesses in a rural teaching hospital – A cross-sectional study, Sangareddy

Background: Liver abscess is a major health problem in tropical and subtropical regions. Aim: The present study aimed to evaluate the clinical profile, management of amoebic liver abscess patients. Materials and methods: A cross-sectional study was conducted in Department of Surgery MNR Medical College Hospital, Sangareddy over a period of 2 years from June 2014 to July 2016. A total of 100 patients with liver abscess were included in this study. Clinical examination, detail case history, ultrasonography reports, case management and outcome were recorded during study. Results: Among 100 patients, 88 were males and 12 were females. Majority of cases were belongs to the age group of 30 -40 years (45%). Most common clinical features of amoebic liver abscess was fever (89%), abdominal pain (78%) and diarrhoea (37%). The major signs were hepatomegaly (87%), right lobe abscess (68%), left lobe abscess (36%) and pleural effusion (18%). Mortality rate was 3% out of 100 patients.

A comparative study of different modalities of treatment of liver abscess.

Objective: To compare the effectiveness of conservative medical treatment versus minimal invasive surgical techniques like percutaneous catheter drainage (PCD) and percutaneous needle aspiration (PNA) in the management of liver abscess. Material and methods: All patients with liver abscess who were admitted in Surgery from October 2013 to June 2014 were included in this study and were exposed to four different treatment modalities. The patients were first treated with combination of medicine (Option-A). If they failed to respond to this treatment then they were subjected to ultrasound guided aspiration (Option -B). If Option - B failed they were exposed to pig tail catheter placement (Option -C). Final option was surgical drainage (Option - D) if it was rupture liver abscess and if the patient presented with co morbid conditions like septicaemia and peritonitis.PNA was repeated every third day if the cavity size had not declined to 50% of the original for up to three times. Persistence of cavity or of clinical symptoms was considered failure of treatment. Results: Out of 51 patients, 14 patients responded to drug therapy alone. 34 patients required ultrasound guided aspiration and Pig tail catheter placement and 3 patients required open surgical drainage. A combination of drug therapy and ultrasound guided needle aspiration was effective for majority of 83% patients Duration of hospital stay was similar in the two groups. Conclusion: Minimal surgical interventions like PCD and PNA are better than conservative treatment for the management of liver abscesses of size >5 cm, in terms of duration to attain clinical relief and duration for which parenteral antibiotics are needed. Pyogenic liver abscess are less common than amoebic liver abscess. Right lobe of the liver is most commonly involved in both types of abscesses. Radio-imaging techniques like ultrasonography (US) and computerized tomography (CT) are the modalities of choice for investigation purposes. Treatment modalities of these abscesses, first emphasizes on medical treatment, but if it is unsuccessful then only the surgical intervention should be taken up. Laparotomy and Drainage or Laparoscopic Drainage remains the standard of care for ruptured liver abscess.

Subcutaneous Seeding of Hepatoid Thymic Carcinoma after Percutaneous Needle Aspiration Biopsy / 대한피부과학회지

Percutaneous needle aspiration biopsy is a reliable and useful procedure for diagnosing tumor with a low rate of complications and high diagnostic reliability. Subcutaneous malignant seeding of the needle tract is a well-known complication of percutaneous needle aspiration biopsy. Implantation metastases of the abdominal and chest walls have been reported after puncturing the tumor lesions of the liver, kidney, adrenal gland, lung and pleura. We report here on a case of subcutaneous seeding of hepatoid thymic carcinoma on the right upper back after a percutaneous needle aspiration biopsy.

A Case of Pulmonary Nocardiosis in the Patient with Cushing's Disease / 결핵및호흡기질환

Even though nocardiosis is one of opportunistic infections, and can occur in Cushing's syndrome, it rarely occurs in patients with Cushing's disease. Herein, a case with Cushing's disease in whom nocardiosis had manifested as a pulmonary lesion, which after percutaneous needle aspiration, empyema and a breast abscess were also noted.

New Paradigm for Patients with Pulmonary Nodule Expecting Thoracoscopic Resection / 대한흉부외과학회지

BACKGROUND: The pulmonary nodules (PN), when indicated, need thoracoscopic resection, especially in cases of non-diagnostic or technically infeasible PCNA (percutaneous needle aspiration). In the difficult situations of small or deeply seated PN, several techniques facilitating thoracoscopy have been used for detecting them. Our new protocol for managing PN was developed and prospectively reviewed. MATERIAL AND METHOD: In the procedure of PCNA, we firstly placed the tip of the needle in the center of, or just in contact with PN under CT guidance, and loaded one or two segments of platinum radiomarker inside the needle after removing the stylet. Then, we forced the radiomarker to move to the tip of the needle by pushing the stylet. Finally, if the tip of the needle was not within PN, it was reoriented to the their center to obtain the sample for PCNA. RESULT: Between May 1999 and May 2000, radiomarkers were successfully placed in 28 PN of 26 patients, with the exception of one. In 18 (85%) of 21 nodules needing throacoscopy, intraoperative fluoroscopy was used to detect them or guide stapling resection during thoracoscopy. CONCLUSION: The advantages of this technique are that there is that there is no need for further localization for thoracoscopy even in cases of unsuccessful PCNA, and it was more effective in respect to both cost and time. Therefore, this strategy for PN expecting thoracoscopy will be helpful to patients and medical staff alike.

Chest Wall Implantation of Lung Cancer after Fine Needle Aspiration Biopsy: 2 cases / 대한흉부외과학회지

Implantation of malignant cells along the needle aspiration tract is an extremely rare potential complication following a percutaneous fine needle aspiration biopsy of a lung carcinoma. The dissemination of malignant cells by a needle aspiration biopsy may convert an operable and potentially curable lesion into a fatal disease. We report two cases of chest wall implantation of carcinoma of the lung after a thin needle aspiration biopsy. A fifty-five year old male was successfully treated by a radical full-thickness excision of the chest wall and immediate reconstruction with the latissimus dorsi musculocutaneous island flap. A sixty-eight year old female was treated with a partial-thickness excision of the chest wall and skin graft due to superimposed infection and ulceration of the metastatic chest wall carcinoma. One case lived for 31 months up to November 1994, and the other's condtion has been uneventful for 3 months up to now.

The Diagnostic Yield and Complications ofPercutaneous Needle Aspiration Biopsy for the Intrathoracic Lesions / 결핵

Bacground: Percutaneous needle aspiration biopsy (PCNA) is one of the most frequently used diagnostic methods for intrathoracic lesions. Previous studies have reported wide range of diagnostic yield from 28 to 98%. However, diagnostic yield has been increased by accumulation of experience, improvement of needle and the image guiding systems. We analysed the results of PCNA performed for one year to evaluate the diagnostic yield, the rate and severity of complications and factors affecting the diagnostic yield. Method: 287 PCNAs undergone in 236 patients from January, 1994 to December, 1994 were analysed retrospectively. The intrathoracic lesions was targeted and aspirated with 21-23 G Chiba needle under fluoroscopic guiding system. Occasionally, 19-20 G Biopsy gun was used for core tissue specimen. The specimen was requested for microbiologic, cytologic and histopathologic examination in the case of obtained core tissue. Diagnostic yields and complication rate of benign and malignant lesions were calculated based on patients' charts. The comparison for the diagnostic yields according to size and shape of the lesions was analysed with chi square test (p<0.05). Results: There are 19.9% of consolidative lesion and 80.1% of nodular or mass lesion, and the lesion is located at the right upper lobe in 26.3% of cases, the right middle lobe in 6.4%, the right lower lobe 21.2%, the left upper lobe in 16.8%, the left lower lobe in 10.6%, and mediastinum in 1.3%. The lesion distributed over 2 lobes is as many as 17.4% of cases. There are 74 patients with benign lesions, 142 patients with malignant lesions in final diagnosis and confirmative diagnosis was not made in 22 patients despite of all available diagnostic methods. 2 patients have lung cancer and pulmonary tuberculosis concomittantly. Experience with 236 patients showed that PCNA can diagnose benign lesions in 62.2% (42 patients) of patients with such lesions and malignant lesions in 82.4% (117 patients) of patients. For the patients in whom the first PCNA failed to make diagnosis, the procedure was repeated and the cumulative diagnostic yield was increased as 44.6%, 60.8%, 62.2% in benign lesions and as 73.4%, 81.7%, 82.4% in malignant lesions through serial PCNA. Thoracotomy was performed in 9 patients with benign lesions and in 43 patients with malignant lesions. PCNA and thoracotomy showed the same pathologic result in 44.4% (4 patients) of benign lesions and 58.1% (25 patients) of malignant lesions. Thoracotomy confirmed 4 patients with malignat lesions against benign result of PCNA and 2 patients with benign lesions against malignant result of PCNA. There are 1.0% (3 cases) of hemoptysis, 19.2% (55 cases) of blood tinged sputum, 12.5% (36 cases) of pneumothorax and 1.0% (3 cases) of fever through 287 times of PCNA. Hemoptysis and blood tinged sputum didn't need therapy. 8 cases of pneumothorax needed insertion of classical chest tube or pig-tail catheter. Fever subsided within 48 hours in all cases. There was no difference between size and shape of lesion with diagnostic yield. Conclusion: PCNA shows relatively high diagnostic yield and mild degree complications but the accuracy of histologic diagnosis has to be improved.

Metastasizing Histologically Benign Giant Cell Tumor: A Case Report / 대한정형외과학회잡지

Giant cell tumor is a relatively uncommon neoplasm with high rate of local recurrence following curettage and bone graft. The histologic grading was not proven useful in predictiog outcome. Histologically benign giant cell tumor may metastasize. We report a case of histologically benign giant cell tumor occurred at left distai femur with local recurrences and multiple pulmonary metastases which was proven by percutaneous needle aspiration lung biopsy. Recurred local lesion was treated by curettage and filling with methylmethacrylate and pulmonary metastases was treated with adriamycine and dacarbazine.
