Biliary ascariasis - role of endoscopic intervention.

Aim: This study was undertaken to review the predisposing factors, presentation and management of patients diagnosed with biliary ascariasis while specifically emphasizing the role played by endoscopy. Methods: We performed a retrospective analysis of nine patients diagnosed and admitted with biliary ascariasis at our center. The diagnosis was based on ultrasound findings and confirmed by detection of round worms in the biliary tract or the descending duodenum. The clinical presentation and management were reviewed. Results: Five of the nine patients had prior biliary sphincter ablative/ bypass procedures for choledocholithiasis; including endoscopic sphincterotomy in four and lateral choledochoduodenostomy in one patient. All but one patient presented with acute onset pain abdomen radiating to the back. One patient presented with features of acute cholecystitis. Ultrasound detected the presence of round worms in all the patients. Endoscopic retrograde cholangio-pancreatogram confirmed presence of worm in the biliary tree. Endoscopic extraction of the worm from the biliary tree or duodenum was successfully undertaken in all the patients and provided prompt relief. One patient had recurrence of infection after eight months which was re-treated by endoscopic extraction. Antihelminthics were instituted in all patients. Conclusion: Biliary ascariasis, should be considered in the differential diagnosis of acute abdomen, particularly in patients who have undergone prior biliary sphincter ablation/ bypass procedures like sphincterotomy or choledochoduodenostomy. Ultrasonography is a reliable diagnostic modality. Endoscopic retrograde cholangiogram confirms the diagnosis and precedes endoscopic extraction of the worm. This offers prompt relief from symptoms.

Bouveret's syndrome--an unusual cause of spontaneous resolution of gastric outlet obstruction.

Gastric outlet obstruction due to a gallstone impacted in the duodenal bulb (Bouveret's syndrome) is a rare complication of gallstones. We report a 47-year-old man with this syndrome in whom the impacted stone migrated uneventfully.

Clinical profile of carcinoma stomach at a tertiary care hospital in south India.

Carcinoma of the stomach is an important cause of mortality due to cancer. Carcinoma of the stomach is common in the southern region of India. We conducted a retrospective study on the epidemiological, clinical and survival patterns among the patients with carcinoma of the stomach, attending our hospital from June 19, 1995 to 1st January 2003. All the patients had histopathological confirmation of malignancy. Patients with gastrooesophageal junction lesions were excluded. Surgery was performed with curative as well as palliative intent in suitable patients. Chemotherapy has been incorporated in to the combined modality treatment in our hospital since July 2000. Postoperative chemotherapy comprised commonly used intravenous chemotherapy regimens, while oral chemotherapy (etoposide) was given to patients with disease not amenable to surgery, and those having poor performance and nutritional status. Oral etoposide was given in a dose of 50 mg/day for 14 days, in a 28 day cycle. Quality of life was assessed in the oral chemotherapy group. Out of the 1749 cancer patients seen during the period, 151 had gastric malignancy (8.6%). The median age was 55 years (range 15-84 years). The male to female ratio was 4:1. Adenocarcinoma was found in 148 patients, 2 had stromal tumours and 1 had non-Hodgkin lymphoma. Stage disribution was as follows; stage 2-1 patient , stage 3a-25, stage3b-49, stage4-3 1, Metastatic-28. Staging was not completed in 17 patients. Eighty-nine patients underwent surgery. Fifty-nine patients (39%) did not have surgery. One patient underwent polypectomy. Curative gastrectomy was performed in 11 patients. Thirty-nine patients underwent palliative tumour resection. Palliative gastro-jejunostomy for relief of symptoms was performed in 26 patients and exploratory laparotomy alone was perforaied in 13. Thirty-eight patients received chemotherapy. Out of these, only 2 patients had prior complete resection of the tumour and 36 received palliative chemotherapy. Intravenous chemotherapy was given to 17 patients and oral chemotherapy to 19; All the patients who received oral etoposide did not experience any toxicity. Patients who received intravenous chemotherapy (n=17) had the following toxicities: grade 3 emesis in 4 (20%), discoloration of the skin and nails in 6(31%), alopecia in 8 (50%), grade 3 diarrhoea in 3 (15%) and neutropenic fever in 4 patients (20%). Median survival for the cohort was 10.4 months. Quality of life parameters, such as sleep, appetite, weight, pain, work and general sense of ill health showed improvement. In conclusion, 8.6% of all cancers at our hospital were due to cancer of stomach, in whom distal gastric tumor were more frequent and most were non-resectable. Median survival was 10.4 months. Oral etoposide was found to be safe, improved the quality of life and may play a role in the palliative management of advanced carcinoma of the stomach.

Bile duct adenoma: management by subtotal excision.

Benign tumours of the bile duct are rare. We report a bile duct adenoma in a young female, which was managed by subtotal excision.

Acute mesenteric venous thrombosis complicating endoscopic variceal sclerotherapy with absolute alcohol.

We report two patients, one with liver cirrhosis and another with extrahepatic portal vein obstruction, who developed acute mesenteric vein thrombosis following endoscopic variceal sclerotherapy with absolute alcohol. Both patients recovered after emergency laparotomy and resection of gangrenous bowel loop.

Abdominal tuberculosis: diagnosis by laparoscopy and colonoscopy.

BACKGROUND: Histopathological confirmation in abdominal tuberculosis is difficult due to suboptimal noninvasive access to the involved area. Peritoneoscopy and colonoscopy provide semi-invasive access to the peritoneum, large intestine and ileocecal area. Information on the diagnostic yield of these two investigation in abdominal tuberculosis is scarce. OBJECTIVE: To evaluate the role of laparoscopy and colonoscopy in the diagnosis of abdominal tuberculosis. PATIENTS AND METHODS: Between January 1998 and July 2001, 34 patients were diagnosed to have abdominal tuberculosis on the basis of laparoscopy or colonoscopy. The case records of these patients were retrospectively reviewed to assess the usefulness of laparoscopy and colonoscopy in the diagnosis of abdominal tuberculosis. RESULTS: Laparoscopy was performed in 23 patients. Peritoneal tuberculosis was diagnosed in 19 of them, characterized by presence of ascites, multiple whitish tubercles, fibrous bands and adhesions, hyperaemic edematous bowel loops or dense adhesions without ascites. Multiple jejunoileal hyperemic short segments with serosal neovascularization was noticed in three patients. One patient had cecal mass with pericecal inflammatory adhesions. In three patients, laparoscopy was converted to open laparotomy due to bowel injury, extensive adhesions, and difficulty in assessing lymph nodal mass in one patient each. Peritoneal biopsy confirmed the diagnosis in 10 of the 15 (67%) patients. In one patient pericecal tissue biopsy confirmed the diagnosis. The remaining patients received therapeutic trial with anti tuberculosis treatment. All patients showed good response. Thus laparoscopy provided positive diagnosis of tuberculosis in 20/23 (87%) and positive histology in 10 of the 15 (67%) patients with peritoneal lesions. Thirteen patients underwent colonoscopy. Mucosal lesions involving terminal ileum, cecum and colon was noted in 11 patients. Colonoscopic biopsy confirmed the diagnosis in six of the 11 patients (54%). Non of these patients had any complication related to colonoscopy. CONCLUSION: Laparoscopy was safe and helped in the diagnosis of peritoneal as well as intestinal tuberculosis in 87% of patients. Colonoscopy is useful for colonic and terminal ileal lesion with a positive diagnostic yield of 54%.

Fatal granulomatous disease of childhood: presenting as acute abdomen.

Fatal granulomatous disease of childhood is a rare disorder of phagocytic function. We report a 6-year-old boy who presented with acute abdomen. The diagnosis was established by mesenteric lymph node biopsy obtained at laparotomy. The boy succumbed within hours of surgery.

Diagnosis of gastrojejunocolic fistula by chromo-colonoscopy.

The role of colonoscopy has not been adequately evaluated in the diagnosis of gastrojejunocolic fistula. We report the findings and complications of routine colonoscopy in four patients and a novel technique 'Chromo-colonoscopy' in the diagnosis of this entity.

Lymphangiovenous malformation--a rare cause of giant retroperitoneal cyst.

A giant retroperitoneal cyst manifesting as congenital inguino-scrotal swelling to begin with, is reported. The abdominal swelling became clinically obvious at the age of five years because of rapid enlargement over a period of one month. A multiloculated cyst was revealed on preoperative ultrasonography. Intracystic hemorrhage necessitated emergency surgical exploration and excision. Histology of the cyst revealed lymph-angio-venous malformation.

Prestomal ileitis.

A case of prestomal ileitis resulting from incomplete ileostomy-stomal obstruction presented with intestinal perforation and massive bleeding perileostomy. The diagnosis and surgical implications of this unusual problem have been discussed.

Solitary non-parasitic cysts of the liver: presentation and management.

Four cases (one asymptomatic and three symptomatic) of solitary non-parasitic cysts of the liver are presented. The asymptomatic cysts was an incidental finding at laparotomy. The other three patients presented with abdominal distension, jaundice and malignant transformation respectively. Management of these patients has been discussed and the literature reviewed.
