Solitary rectal ulcer syndrome: characteristics, outcomes and predictive profiles for persistent bleeding per rectum.

INTRODUCTION: Solitary rectal ulcer syndrome (SRUS) is a rare disorder of defaecation and persistence of symptoms is common, particularly bleeding per rectum (BPR). This study assessed the clinical, endoscopical characteristics and predictive profiles for persistent BPR. METHODS: 28 patients (14 males) with biopsy-proven SRUS were identified from 1989 to 2003, and the clinical and endoscopical findings were retrospectively reviewed. RESULTS: At presentation, the mean age was 29.5 +/- 16.1 (range ten to 81) years. Common symptoms reported included BPR (86 percent), abdominal pain (36 percent), mucus per rectum (25 percent), straining at defaecation (25 percent), diarrhoea (14 percent) and constipation (14 percent). Digital manual evacuation was reported by 11 percent. 68 percent were anaemic and 57 percent required blood transfusion. Lesions were located anteriorly (38.5 percent), posteriorly (30.7 percent) and circumferentially (31.8 percent). The lesions were multiple (34 percent), ulcerative (64.3 percent) and polypoidal/nodular (32.1 percent). At a mean follow-up of 43.5 +/- 36 months, 64 percent (n=18) had multiple admissions (mean 3.1, range one to 12), mainly for transfusion (mean 7.4 units, range two to 27). There was no difference in clinical responses between patients with polypoidal/nodular or ulcerative lesions (p-value is 0.653). Follow-up endoscopies showed improvement (58 percent), progression (21 percent) and no change (21 percent) in the lesions. Four patients had surgery for concerns of neoplasms (n=2) and persistent BPR (n=2). BPR was persistent in 39 percent. Presence of abdominal pain (p-value is 0.008) and passage of abnormal stool (p-value is 0.002) were predictive of persistent BPR. CONCLUSION: SRUS occurs predominantly in young patients and despite being a benign condition, morbidity remains a problem. Patients' profiles are predictive of persistent BPR.

Differentiation of typhoid fever from fulminant hepatic failure in patients presenting with jaundice and encephalopathy.

OBJECTIVE: To determine the clinical and laboratory features that allow the early diagnosis of typhoid fever in patients who present with jaundice and encephalopathy. PATIENTS AND METHODS: This 12-month prospective study, conducted in Bangalore, India, between 1990 and 1991, evaluated the clinical and laboratory features of all patients (N=47) who presented with encephalopathy within 8 weeks of onset of jaundice. Ciprofloxacin and dexamethasone were used to treat 11 patients diagnosed on blood culture as having typhoid fever. The other 36 patients were presumed to have fulminant hepatic failure with a viral cause and were treated with supportive measures (bioartificial liver support and transplantation were not available). RESULTS: In patients with jaundice and encephalopathy, a liver span of greater than 9 cm on physical examination, thrombocytopenia, elevated alkaline phosphatase level, aspartate aminotransferase level greater than alanine aminotransferase level, and only mild prolongation of the prothrombin time suggested a diagnosis of typhoid fever. All 11 patients diagnosed as having typhoid fever had an excellent response to treatment with ciprofloxacin and dexamethasone with no mortality and with normalization of the liver test results in 2 weeks. On the other hand, 30 of the 36 patients with nontyphoid fulminant hepatic failure died. CONCLUSIONS: In patients presenting with jaundice and encephalopathy, physical examination and simple laboratory tests can help make an early diagnosis of typhoid fever. We believe that patients with a presumptive diagnosis of typhoid fever should be treated with ciprofloxacin and dexamethasone, even before the results of blood cultures are available.

Pancreatic ascites in children.

We report on three children with pancreatic ascites confirmed by endoscopic retrograde cholangiopancreaticography (ERCP) and treated with surgery. The children presented with ascites, malnutrition and severe weight loss. Pancreatic ascites was diagnosed by elevated ascitic fluid and serum amylase levels. ERCP demonstrated a pseudocyst and the site of disruption of the pancreatic duct, but not the etiology of the pancreatitis. Following a period of nutritional support, surgery was carried out. Two of the children underwent a stented transgastric drainage of the pseudocyst; a recurrent pseudocyst in one of the children required a revision cystojejunostomy. The third child was treated with a Roux-en-Y cystojejunostomy. All the children are pain-free and without ascites and are doing well on long-term follow-up. We conclude that pancreatic ascites must be considered in the differential diagnosis of intractable ascites in children. An ERCP is essential in planning management and cystoenterostomy is the definitive treatment.

Non-conventional portosystemic shunts in children with extrahepatic portal vein obstruction.

Portal hypertension due to extrahepatic portal vein obstruction is ideally treated by the use of a selective shunt. In a four year period between July 1987 and June 1992, 50 surgical procedures were carried out in 48 children with portal hypertension-related variceal hemorrhage. The portal, splenic, mesenteric, or coronary vein was not available for anastomosis in four children who, therefore, underwent non-conventional shunts which are described here. There was no postoperative mortality. One patient had a repeat gastrointestinal hemorrhage, probably due to stenosis of the shunt and failure to ligate the coronary vein. No rebleeding occurred on follow-up of at least 18 months. We conclude that in selected children requiring surgery for portal hypertension due to extrahepatic portal venous obstruction, a non-conventional shunt may be used with beneficial results.

Peanut agglutinin binding by gastric mucosal epithelial cells in Helicobacter pylori associated gastritis.

Gastric biopsies (42) from patients with peptic ulcer disease were classified into Helicobacter pylori positive (32) and negative (10) groups, based on the results of tissue urease test and microscopic demonstration of spiral bacteria. A statistically significant difference in peanut agglutinin (PNA) binding between the two groups was observed, attributable to exposure of sialic acid residues on gastric epithelium in the H. pylori positive group. That the negative binding was due to sialic acid, was further confirmed by application of sialidase digestion technique. These results support the existing biochemical evidence for exposure of sialic acid residues on H. pylori colonized epithelium.

Colonoscopic polypectomy in children.

Between January 1984 and July 1990, a total of 129 colonoscopic snare polypectomies were performed during 77 sessions on 74 patients aged 2 to 12 years. Bleeding per rectum (mean duration, 10 months) was the chief presenting symptom and was present in all of these patients. In 89% of patients polypectomy was carried out without using general anesthesia. Ninety-six percent of patients had juvenile polyps. Two patients had familial polyposis coli and one patient had a solitary adenomatous polyp. The majority (98; 80%) of the polyps were located in the rectosigmoid region. Four patients developed complications, one needing emergency operation. There were no deaths in the series. It is concluded that colonoscopic snare polypectomy is a simple, effective, and safe procedure for treating colorectal polyps in children.

Ispaghula therapy in irritable bowel syndrome: improvement in overall well-being is related to reduction in bowel dissatisfaction.

This placebo controlled, double-blind, cross-over trial involving 20 patients was conducted to assess the effect of ispaghula husk on the major bowel symptoms and the whole gut transit time in irritable bowel syndrome (IBS) and to determine if changes in these parameters were related to global improvement. All 20 patients were interviewed at the end of the treatment periods and 14 patients kept concurrent daily records. Ispaghula therapy resulted in improvement in global symptoms and satisfying bowel movements (P less than 0.001) but produced no change in abdominal pain or flatulence. There was a correlation between the improvement of well-being and the number of days of satisfying bowel movements (P less than 0.001) but not with the indexes of pain, stool frequency or changes in the transit time. The easing of bowel dissatisfaction appears to be a major reason for the therapeutic success of ispaghula in IBS.
