Laparoscopic cholecystectomy: an Indian experience of 1233 cases.

BACKGROUND: Laparoscopic cholecystectomy (LC) is a well-established procedure for symptomatic cholelithiasis in India, but there are few data available regarding the procedure and its related complications. PATIENTS AND METHODS: This paper represents a retrospective review of 1233 patients who underwent LC at Government Medical College and Hospital, Chandigarh, India, over 4 years (1997-2000). The case files of all these patients were analyzed for patient particulars, intraoperative findings, reason for any open conversion, postoperative stay, and mortality. RESULTS: The overall conversion rate was 7.06% (87 patients). The commonest cause of conversion was a frozen Calot's triangle (52 patients), followed by injury to the common bile duct (8 patients). The average postoperative stay in successful LC was 1.32 days. The overall mortality rate was 0.16% (2 deaths). The quality of life after LC was good to excellent in more than 90% of patients. CONCLUSIONS: Despite multiple hands in training, the complication rates of LC are within acceptable limits. The overall conversion rate has risen because of the increase in elective conversions, but the incidence of complications has come down because of a "no hesitation" policy in converting. In spite of multiple operators, LC is the procedure of choice for symptomatic cholelithiasis at our hospital.

Current perspectives in gallbladder carcinoma.

Carcinoma gallbladder (CaGB) is not a common malignancy in a large number of countries in the world, except Chile, Japan, some parts of India, and a few other regions. Lacunae exist even today in terms of understanding of its epidemiology, aetiopathogenesis, and in the early pick up of malignanacy, as well as in choosing the most appropriate treatment option for a given case. While Japanese surgeons have advocated radical resections for CaGB and have shown good outcome resulting in long- term survival, others have not felt convinced about the desirability of undertaking such morbid surgical procedures in all patients. Also, radical resections have not always resulted in a tumor-free state and a cure in a large percentage of cases. Under the circumstances, the clinician's mind is often confused as to the most beneficial option for that patient once curative resection is not possible. Palliation of the jaundice and/or gastric outlet obstruction relieves the symptoms but does not prolong survival. The role of adjuvant chemotherapy with or without cytoreductive surgery has not been fully explored in CaGB. The present review quotes experience that seems to support the above contention. However, a number of well-designed multicentric trials are required to confirm the above philosophy of treatment for the benefit of patients suffering from CaGB.

Autoimmune hepatobiliary disease in trisomy 21.

Two patients with abnormal liver biochemistry are presented with hepatobiliary disorders rarely described in trisomy 21. The first was considered to have primary sclerosing cholangitis (PSC) and Crohn's disease. Liver biochemistry was normal after six months' treatment with ursodeoxycholic acid and diarrhea resolved after sulfasalazine. The second patient had autoimmune hepatitis that responded to immunosuppression. Autoimmune hepatobiliary disorders, highlighted by this report, occur in trisomy 21 but are rare. A high index of suspicion for these potentially treatable disorders is required.

An audit of percutaneous endoscopic gastrostomy in a general hospital in Singapore.

OBJECTIVE: We conducted an audit on 50 percutaneous endoscopic gastrostomies (PEGs) performed by physician endoscopists from January 1996 up to November 1997. DESIGN: A retrospective cohort study was conducted. RESULTS: The mean age of the patients was 68.5 years (range 20-101) and the main indications were cerebrovascular accident in 40 (80%), neurological dysphagia in six (12%) and head injury in three (6%). The interval between the diagnosis of dysphagia and PEG was > 60 days in 19 patients (38%), 31-60 days in eight (16%) and < or = 30 days in 23 (46%). The commonest reason for PEG insertion was intolerance to nasogastric tube in 49 patients (98%). Twelve patients had antibiotics given concurrently for other infections and two had antibiotics given specifically to cover PEG insertion. There was evidence of post-PEG infection in two of 14 patients given antibiotics (14%) and in 14 of 36 patients not given antibiotics (39%). By Cox regression, the adjusted relative risk of infection in patients receiving antibiotics versus those not receiving was 0.6927 (95% CI 0.3396-1.4130; not significant). The 30-day mortality was 7/48 patients (15%), with two patients lost to follow-up before 30 days. There were no deaths directly attributable to PEG. CONCLUSIONS: PEG is still not adequately requested by doctors for patients needing enteral feeding for more than 30 days. The use of antibiotics in this retrospective cohort study failed to show any benefit in reducing the rate of infective complications.

Helicobacter pylori eradication with lansoprazole, amoxycillin and clarithromycin: testing an ideal regimen in a multicultural south east Asian population and examining factors potentially influencing eradication.

BACKGROUND: From European and North American data, it is recommended in the Asia Pacific consensus statement, that one week therapy with a proton pump inhibitor, amoxycillin and clarithromycin be used for Helicobacter pylori eradication, in areas of high metronidazole resistance. The efficacy of this regimen is unknown in Singapore. AIM: To assess the efficacy, safety and compliance of an H. pylori eradication regimen and examine clinical factors that potentially determine eradication. METHODS: Consecutive outpatients from a multicultural, south east Asian, population with H. pylori infection, with or without peptic ulcer, were treated with lansoprazole 30 mg, amoxycillin 1 gm, clarithromycin 500 mg, twice a day for seven days. Eradication was assessed by either rapid urease, histology or urea breath test. Compliance and side effects were recorded. The eradication rate and effect of ethnicity, age, sex, usage of alcohol, smoking and non-steroidal anti-inflammatory drugs, history of ulcer and endoscopic diagnosis on eradication were examined by univariate and multivariate analysis. RESULTS: Of 113 patients, the eradication rate by intention to treat was 98/113 (87%) (95% confidence interval [CI] 80-93%) and per protocol was 98/106 (92%) (95% CI 87-97%). Using Fisher's exact test, eradication was more successful in Chinese (intention to treat and per protocol respectively p=0.02 and p<0.001) compared to non-Chinese. By logistic regression analysis ethnicity was an independent factor associated with eradication success (p=0.0025). Side effects occurred in five (4.4%), resulting in cessation of treatment. CONCLUSIONS: This one week eradication regimen is safe and effective in south east Asians. Chinese ethnicity may be associated with a higher likelihood of eradication success.

An unusual manifestation of severe caustic injury.

Knowledge of the sequelae of caustic ingestion is of relevance to staff of the Emergency Room, Intensive Care Unit, surgical and gastroenterology services. It poses a considerable management problem and may result in life-threatening complications such as visceral perforation. This case report demonstrates an unusual and previously unreported manifestation of caustic injury.

Weils' syndrome and concomitant hepatitis B infection.

Leptospirosis is a ubiquitous, spirochetal zoonosis which presents with a broad clinical spectrum. Weil's syndrome, characterised by jaundice, renal failure and bleeding manifestations is the most severe form. A high index of suspicion for the diagnosis is required to institute therapy promptly. We describe a case of serologically confirmed Weil's syndrome with concomitant hepatitis B infection.

Gall bladder cancer: proposal for a modification of the TNM classification.

Gall bladder cancer is the commonest biliary tract malignancy. The TNM classification of AJCC-UICC is the most widely accepted and most commonly used system for staging. We propose some modifications in the existing classification and recommend guidelines for management based on the stage of the disease.

Duodenogastric reflux after choledochoduodenostomy.

Duodenogastric reflux (DGR) has been implicated in several disease processes. The present study was carried out to document the incidence and evaluate the clinical significance of DGR after choledochoduodenostomy (CDD). A total of 13 patients who had undergone cholecystectomy with a standard side-to-side CDD for choledocholithiasis or chronic pancreatitis were studied by symptom evaluation, scintigraphy, endoscopy, and gastric mucosal histology at least 6 months after surgery. The scintigraphic findings were then compared with those of 10 patients who had undergone cholecystectomy alone. Only two patients (15%) had mild dyspeptic symptoms. The incidence of DGR after CDD was 69% compared to 20% in the cholecystectomy alone group (P < 0.05). In the majority of patients the DGR was only mild to moderate and the severity correlated well with the degree of endoscopic gastritis, but not with the clinical symptoms or histological findings. These results indicate that while CDD is associated with a high incidence of DGR, its occurrence does not produce significant clinical symptoms.

Post-cholecystectomy external biliary fistula.

BACKGROUND: External biliary fistula (EBF) following bile duct injury is a serious complication of cholecystectomy. METHODS: From January 1989 to December 1994, 37 patients with post-cholecystectomy external biliary fistula were seen at this centre. There were 14 partial, 22 complete and one sub-vesical duct of Luschka injury. Sixteen patients had a controlled EBF at presentation; 10 patients had intra-abdominal collections and seven patients presented with peritonitis. RESULTS: A staged approach to the management of these patients was adopted in which the initial management aimed at creating a 'controlled' fistula. This approach comprised conservative treatment (n = 9), percutaneous catheter drainage of intra-abdominal collections (n = 10), biliary drainage (n = 6), and surgical intervention (n = 7). One patient died because of progressive liver failure in spite of intensive management. Definitive management comprised the surgical repair of biliary strictures wherever indicated, after waiting for the acute problems to settle. CONCLUSIONS: By adopting a staged approach along with a judicious use of endoscopy, radiology and surgery that were based on clinical circumstances, it was possible to achieve satisfactory results for this otherwise distressing condition.

Toxocara canis infection and granulomatous hepatitis.

This report describes possible involvement of Toxocara canis in granulomatous hepatitis in three patients who presented with varied clinical features; two were being treated for other diagnoses until Toxocara serology became available. Despite initial nonspecific therapy, there was clinical improvement in all patients and complete resolution of symptoms and abnormal liver biochemistry in two. T. canis infection should be considered in cases of granulomatous hepatitis.

Early carcinoma of the gallbladder: an elusive disease.

Prognosis of carcinoma of the gallbladder can be improved by diagnosing the disease in the early stages. Records of 14 patients with early (UICC AJCC TNM stages I and II) carcinoma of the gallbladder were analyzed. Clinical presentation in all these patients was like benign biliary disease. Ultrasonography could diagnose carcinoma of the gallbladder in only five patients; in the remaining nine patients, even the ultrasonographic diagnosis was benign biliary disease. All patients were operated; carcinoma of the gallbladder was diagnosed at operation in two more patients, but it was first detected only after histological examination in seven patients. All patients except four had associated gallstones. Preoperative diagnosis of early carcinoma of the gallbladder is difficult. The only way to diagnose early carcinoma of the gallbladder is by early surgical treatment of patients with clinical features of benign biliary disease.

Intrahepatic segment III cholangiojejunostomy in advanced carcinoma of the gallbladder.

The majority of patients with advanced carcinoma of the gallbladder have irresectable disease and require palliation for jaundice, pruritus and cholangitis. Intrahepatic segment III cholangiojejunostomy has been described for palliation of high biliary obstruction in these patients. Forty-one patients with stage IV gallbladder cancer underwent intrahepatic segment III cholangiojejunostomy. Subsequent jaundice, pruritus and cholangitis were documented; liver function tests and isotope hepatobiliary scans were performed. All patients had jaundice, 29 had pruritus and 12 had cholangitis. Postoperative complications included anastomotic leak in six patients and wound infection in six. Five patients died within 30 days of operation. Thirty-two patients were available for follow-up. The procedure failed to relieve jaundice, pruritus or cholangitis in four patients; 18 were free of jaundice, pruritus and cholangitis until death or last follow-up, and ten had recurrent jaundice or cholangitis. Isotope scanning was found to be useful to predict success of the procedure. Intrahepatic segment III cholangiojejunostomy provided excellent palliation from jaundice, pruritus and cholangitis with acceptable mortality and morbidity rates in patients with advanced carcinoma of the gallbladder.
