Outcomes of a conservative approach to management in amoebic liver abscess.

CONTEXT: Unfortunately, there is confusion among the medical community regarding the management of amoebic liver abscess (ALA). Therapeutic options range from simple pharmacotherapy to use of interventions like a needle or catheter aspiration under ultrasound guidance to surgical intervention. There is a plethora of thresholds for parameters such as the maximum diameter of the abscess and volume on ultrasound examination suggested by various authors to serve as a criterion to help to decide when to use which modality in these cases. AIMS: To assess the outcome of patients with uncomplicated ALA treated using a conservative approach. Moreover, to identify factors associated with its failure. SETTINGS AND DESIGN: A prospective, observational study was carried out at a large municipal urban health care center over a period of 3-year (2011-2014) in India. MATERIALS AND METHODS: Patients with uncomplicated ALA were recruited. All patients were managed with pharmacotherapy initially for a period of 72 h. Response to treatment was assessed by resolution of symptoms within the given time frame. Failure to respond was considered an indication for intervention. Needle aspiration was offered to these patients and response assessed within 72 h. Failure to respond to aspiration was considered an indication for catheter drainage. STATISTICAL ANALYSIS USED: Data recorded were entered in a Microsoft Office Excel Sheet and analyzed using the SPSS version 16.0 (IBM). RESULTS: Sixty patients with ALA were included in the study over its duration. Forty-nine (81.67%) patients were managed conservatively, while 11 (18.33%) patients needed an intervention for relief. Patients who required intervention had deranged liver function at presentation, a larger abscess diameter (10.09 ± 2.23 vs. 6.33 ± 1.69 cm P < 0.001) and volume (399.73 ± 244.46 vs. 138.34 ± 117.85 ml, P < 0.001) compared to those who did not need it. Patients that required intervention had a longer length of hospital stay (7.1 ± 2.4 vs. 4.8 ± 0.9 days, P < 0.001). On post hoc analysis, a maximum diameter of >7.7 cm was found to be the optimal criterion to predict the need of intervention in cases of ALA. CONCLUSIONS: A conservative approach is effective in the management of ALA for a majority of patients. Failure of conservative management was predicted by the size of the abscess (maximum diameter >7.7 cm). Even in the cases of failure, a gradual step-up with interventions was found to be safe and effective.

Reuse of single-use devices: looking back, looking forward.

The reuse of medical devices marked as 'single use' by manufacturers has been going on for several decades. The process has been rationalized and legislated in the West as well as in Japan. However, the practice continues in an unregulated manner in India due to a paucity of guidance from the Food and Drug Administration in India. We trace the evolution of reuse policies, look at the prevalent practices in the Indian and international contexts, analyse the available Indian literature and address the ethical and economic implications of reuse. We also suggest some guidelines which may be adopted to formulate policies.

Use of adrenal vein conduit for splenorenal shunts: a case report.

We report a case with extrahepatic portal venous obstruction (EHPVO), who presented with recurrent bleeding following a previous devascularization procedure and needed an emergency distal spleno-renal shunt (DSRS). Due to technical difficulty because of previous scarring, the adrenal vein was used as a conduit between the splenic vein and renal vein. The shunt's patent and the patient has been bleed-free for 2 years.

Treatment of symptomatic polycystic liver disease with resection-fenestration.

Polycystic liver disease with severe symptoms is difficult to treat. We report a 35-year-old man with advanced disease, who had a successful outcome after resection and fenestration.

Splenic abscess--a possible complication of endoscopic variceal sclerotherapy.

Endoscopic variceal sclerotherapy, though a safe and effective therapy for esophageal varices, is not devoid of local and distant complications. We report a patient with postnecrotic cirrhosis and diabetes mellitus who developed a splenic abscess while on a sclerotherapy program. The abscess may have been a consequence of retrograde thrombosis of the portal venous system or of bacteremia following sclerotherapy.

Helicobacter pylori gastritis masquerading as gastric lymphoma.

A 30-year-old man presented with acute acid-peptic symptoms. Endoscopy and radiological studies revealed generalized thickening of gastric folds with multiple superficial ulcerations and infiltration of the distal stomach simulating gastric neoplasm. Endoscopic biopsies revealed acute gastritis with foveolar hypertrophy with numerous Helicobacter pylori. The symptoms and endoscopy findings resolved completely with combination triple-drug therapy for H pylori.

Bleeding isolated gastric varices: a retrospective analysis.

OBJECTIVE: Isolated gastric varices (IGV) are rare and are believed to be associated with left-sided portal hypertension. We studied patients presenting with bleeding from IGV and compared them with those bleeding from both esophageal and gastric varices. METHODS: A retrospective analysis of 14 patients with bleeding from IGV was carried out. Portovenography findings (pattern of collateralization and natural shunts) in these patients were compared with a matched group of 69 patients with both esophageal and gastric varices. RESULTS: Of 14 patients with IGV, 2 had isolated splenic vein thrombosis and 12 had generalized portal hypertension. Portovenograms in 11 of the latter 12 revealed predominantly 'left-sided' collateralization in 8 patients as compared to 17 of 69 (25%) patients with esophageal and gastric varices (p = 0.004); natural shunts were seen in 6 of 11 cases and 15 of 69 (22%) patients in the two groups, respectively (p = 0.05). Abdominal devascularization operation gave good short- and long-term control of bleeding. CONCLUSIONS: Contrary to belief most patients with isolated gastric varices may have generalized portal hypertension rather than splenic vein obstruction as the cause and hence should be treated by a more extensive procedure than just splenectomy. The IGV could be a result of predominant collateralization to the retroperitoneal area (left-sided collateralization and natural shunts) rather than the usual pattern to the azygos system which results in esophageal varices.

Total hepatic vascular exclusion for major hepatic resection.

Use of vascular occlusion techniques during hepatic resection has besides decreasing blood loss improved the feasibility of surgical extirpation of large hepatic tumors. We report successful use of this technique to resect a large hepatoma in the right lobe of the liver. The hemodynamic and biochemical changes in the perioperative period are documented.

Fibrolamellar hepatocellular carcinoma.

Fibrolamellar hepatocellular carcinoma, a histological variant of hepatocellular carcinoma, distinct pathological and clinical features and a better prognosis than other types of hepatocellular carcinoma. We report here a patient who was treated on successful surgically.

Surgical management of the Budd-Chiari syndrome: early experience.

BACKGROUND: Early decompression is needed in the Budd-Chiari syndrome (BCS) to prevent liver dysfunction and death. AIMS: To study the technical difficulties during surgery and the results of surgery for BCS. METHODS: Retrospective review of nine patients operated on between 1994 and January 1998 for BCS--1 for uncontrolled fundal variceal bleed and 8 for chronic BCS. Isolated hepatic vein block was found in 5, inferior vena cava (IVC) block in 1 and a combination in 3 patients. Preoperative liver biopsies did not reveal cirrhosis in any patient. Portacaval shunt (3), portorenal shunt (2), mesocaval shunt (1), mesoatrial shunt (2) and devascularisation (1) were the operations performed. RESULTS: In 3 patients, side-to-side portacaval shunt was not possible because of caudate lobe hypertrophy (1), aberrant right hepatic artery (1) and presence of IVC stent (1); they required portorenal (2) or interposition mesocaval (1) shunts. Both mesoatrial shunts were unsuccessful. Devascularisation was effective in controlling the acute bleed. There was no intraoperative death. Postoperatively there were 3 deaths. Of the 6 survivors, 5 are asymptomatic over a mean follow up of 19.7 months. CONCLUSIONS: Side-to-side portacaval shunt is effective in the management of BCS; results with the mesoatrial shunt are disappointing.

Hepatic sickling crisis mimicking recurrent cholangitis.

A 22-year-old man with homozygous sickle cell disease presented with recurrent fever, right upper quadrant pain and jaundice. Liver biopsy confirmed the diagnosis of hepatic sickling crisis; the symptoms responded to hydroxyurea therapy. Hepatic vasocclusive crisis can diagnosed on liver biopsy, and need not be a diagnosis of exclusion.
