Two-phase dynamic contrast-enhanced computed tomography with water-filling method for staging of gastric carcinoma.
The objective of the study was to evaluate the usefulness of two-phase incremental contrast-enhanced computed tomography (CT) with water-filling method in the preoperative assessment of stomach carcinoma. Dynamic CT was done in 20 patients with biopsy-proven gastric cancers and the findings were compared with surgery. A 150-ml ionic contrast medium was administered intravenously at a flow rate of 3.5 ml/s. CT scanning was done at 45 s (early phase) and 3 min (equilibrium phase) after the start of intravenous injection. Primary tumors were detected in all the cases. The overall accuracies of dynamic CT in determining depth of tumor invasion, pancreatic invasion, adjacent liver infiltration, and lymph node metastasis were 85% (17/20), 90% (18/20), 85% (17/20), and 69% (13/19), respectively. The early phase of dynamic CT is highly accurate in determining the depth of tumor invasion of advanced gastric cancers but has low sensitivity in the detection of nodal metastasis. The delayed phase scans do not add any additional information and hence, should not be routinely used for staging.

Antipyrine elimination test as a guideline for selecting patients for transhepatic biliary drainage.
Antipyrine elimination halflife (AP t1/2) was studied in 18 patients with obstructive jaundice along with routine liver function tests 24-48 h before the expected time of percutaneous transhepatic biliary drainage (PTBD). To see if it is possible to predict the outcome of PTBD, various predrainage parameters were correlated with the postdrainage bilirubin clearance after 1 week of drainage. Predrainage AP t1/2 correlated best with bilirubin clearance (r = 0.775, P less than 0.01) compared with predrainage serum bilirubin, alkaline phosphatase and serum proteins/albumin. Eight patients had AP t1/2 less than 15 h, while 10 had AP t1/2 greater than 15 h. Patients with AP t1/2 less than 15 h had significantly faster recovery after PTBD than patients with AP t1/2 greater than 15 h. If PTBD can be restricted to those with AP t1/2 less than 15 h, the advantages of preliminary PTBD can be achieved with minimum complications. Thus, estimation of AP t1/2 may aid in the selection of patients with obstructive jaundice who are likely to benefit by preliminary biliary decompression.

Concurrent renal transitional cell carcinoma and right colon cancer.
A 45-year-old man who had undergone right radical nephrectomy for transitional cell carcinoma 3 months earlier was admitted with right colonic tumor. Review of CT done for right kidney tumor was suggestive of right colon pathology. Right hemicolectomy was performed, followed by a course of chemotherapy for mucinous adenocarcinoma, and he is well a year later.

Pneumobilia--clue to an unusual cause of diarrhea.
A 65-year lady presented with diarrhea and weight loss of six months duration. Initial evaluation suggested that malabsorption was the possible underlying mechanism for the diarrhea. Work up for the common etiologies of malabsorption was non-contributory. Presence of pneumobilia raised the suspicion of a bilio-enteric fistula, which was subsequently confirmed on barium enema and endoscopic cholangio-pancreaticography to be a cholecystocolic fistula. At surgery, a fistulous tract from the fundus of the gallbladder was found to be communicating with the hepatic flexure. Fistulectomy with cholecystectomy resulted in prompt relief of symptoms. Cholecystocolic fistula (CCF) is a rare biliary fistula with diverse presentation.

Comparison of multidetector computed tomographic colonography and conventional colonoscopy for detection of colorectal polyps and cancer.
BACKGROUND: Computed tomographic colonography (CTC) is a new technique for detecting colonic neoplasms. Data on the utility of this method in the Indian population are limited. METHODS: Forty-two patients with symptoms of colonic disease underwent CTC and conventional colonoscopy (CC) within one week of each other and the findings at these two investigations were compared. RESULTS: The entire colon could be evaluated in 38 patients on CTC and in 23 patients on CC. Of the 19 patients who had incomplete CC, 14 had occlusive colonic lesions. Of the 86 lesions detected on CC, 76 (88.4%) were correctly identified on CTC with regard to location and size. CTC was false negative for 10 lesions and false positive for 5 lesions in 3 patients. The sensitivity and specificity of CTC were 65% and 77%, respectively, for lesions 1-5 mm; 97% and 83% for 6-9 mm-sized lesions; and 100% and 100% for lesions 10 mm or larger. Extracolonic findings were seen in 24 of 42 patients (57%). CONCLUSIONS: CTC is reliable for detecting lesions 6 mm or larger in size. It permits evaluation of the region proximal to an occlusive growth, which is often not possible with CC.

Gastro-intestinal injuries in abdominal trauma.
Management of 55 patients of gastro-intestinal injuries has been reviewed. Eighty percent of the patients presented with generalised peritonitis and jejunum was the commonest segment of the bowel injured. Pneumoperitoneum co-related poorly with intestinal disruption. It was present in 35.8 per cent of the cases. Repeated physical examination was found to be paramount importance. Sixty percent of the patients has associated intra-extra-abdominal injuries. Preoperative shock, multiple hollow visceral injury, septicemia, and location of injury (colon and duodenum) were significant prognostic factors associated with the high mortality. Mortality in the series was 25.4 per cent.

Amebic perforation of the colon.
Acute necrotising colitis and perforation of the colon due to amebic infection is usually fatal. Only three patients in the present series of nine survived surgery. Preoperative diagnosis was not possible and because of an extremely friable, blotting paper like colon, this condition was only suspected at laparotomy. Examination of ulcer scrapings for the presence of Entamoeba histolytica or histopathology is confirmatory. Resection anastomosis is mandatory as less extensive local procedures or bypass surgery are not always feasible.

An audit of pneumatic dilatation and oesophagomyotomy in patients with achalasia cardia.
The role of pneumatic dilatation and oesophagomyotomy in the management of achalasia cardia was evaluated. Twenty patients with achalasia cardia managed either by pneumatic dilatation (n = 10) and oesophagomyotomy (n = 10) were studied. Patients undergoing dilatation were followed up for a mean of 20 months (12-30 months) and those undergoing myotomy for 17 months (6-48 months). The patients were evaluated clinically, radiologically and endoscopically. Relief of dysphagia was excellent in 20%, good in 50% and fair in 30% of those who underwent dilatation. In the myotomy group, 60% had an excellent result, 30% had a good result and fair results was observed in 10%. Oesophagitis on endoscopic evaluation, was found in two patients in myotomy group. The diameter of the gastro-oesophageal junction increased from a mean of 2 mm (range 1 to 4 mm) to a mean of 11 mm (range 4 to 15 mm) in dilatation group while in myotomy group it changed from a mean of 2 mm (range 0.5 to 8 mm) to a mean of 9 mm (range 5 to 15 mm). Symptomatic improvement was better after myotomy than after pneumatic dilatation and correlated poorly with radiological features.

Management of duodenal trauma.
The surgical management of fifteen cases of duodenal trauma is reported. Blunt injury of the abdomen was the commonest mode of injury. Thirteen patients (86.6%) had associated intra-abdominal and/or extra-abdominal injuries. Diagnosis of duodenal injury was made at laparotomy in all patients. In the majority of patients (n = 11), either duodenal repair, or anastomosis with the pylorus or jejunum was done. Duodenal diverticulization or pancreaticoduodenectomy were undertaken in 2 patients each. Feeding jejunostomy was an important adjunct for nutritional support. Septicemia with multisystem organ failure and duodenal fistula were lethal complications. Mortality in the present series was 46.6%.

Long common channel syndrome as etiology of choledochal cysts and pancreatitis--two instructive cases.
The aetiology of choledochal cysts is controversial. The authors report two cases of Type I C and Type IV B choledochal cysts; both showing axial dilatation of the common bile duct and common hepatic ducts, single fusiform (Type IC) and multiple cysts of extrahepatic ducts only (Type IVB). Both had anomalous junction of the pancreaticobiliary ductal system as delineated on ERCP leading to the formation of a long common channel. Both these female patients presented in the third decade of life with 7-8 years history of repeated episodes of right upper abdominal and epigastric pain suggestive of pancreatitis. Similar pain was precipitated in both patients following ERCP with raised serum amylase. Hepatico-enterostomy gave lasting relief in both these patients.

Abdominal cocoon in a male: rare cause of intestinal obstruction.
Abdominal cocoon, which is characterised by encasement of bowel by a fibrous membrane, is a rare cause of intestinal obstruction. It occurs primarily in females with only three cases reported earlier in males. We report a male patient presenting with small bowel obstruction and detected to have abdominal cocoon at surgery. Incision of thick membrane and lysis of adhesions led to relief of obstruction without any recurrence.
