Diagnosis of ileocecal and colonic tuberculosis by colonoscopy

The colonoscopic findings in 11 proven cases of ileocecal tuberculosis consisted of deformed ileocecal valve in all 11 and contracted cecal lumen in 10. This was associated with mucosal nodules predominantly around the ileocecal valve, pseudopolypoid folds, and mucosal protuberance. Two patients had an isolated cecal ulcer. In three of the 11 patients the examination enabled a histologic diagnosis to be made on the basis of typical granuloma. In the other four patients Mycobacterium tuberculosis was isolated from the tissue obtained through biopsies.

Laparoscopy for pre-operative staging and assessment of operability in gastric carcinoma

Laparoscopy was performed in 40 patients with gastric carcinoma, whose lesions were otherwise considered amenable to operation, in order to more accurately stage the disease and ascertain the prospect of resectability. Laparoscopy disclosed hitherto unrecognized distant metastases in 5 cases (12.5%) and locally advanced, unresectable neoplasia in 11 cases (27.5%). Thus, laparoscopy served as a basis for avoiding the burden of futile laparotomy in 16 patients (40%). Laparoscopy confirmed the feasibility of resection in 24 patients, and this finding was borne out in 20 of 23 patients surgically explored (87%). The overall diagnostic accuracy of laparoscopy was 91.6%. Laparoscopy was performed in these patients with no mortality or morbidity. We conclude that laparoscopy is an effective means of evaluating resectability of gastric carcinomas and can provide valuable help in planning surgical approach.

Adult Bochdalek hernia—Clinical features, management and results of treatment

We herein present 2 cases of adult Bochdalek hernia. Only a total of 51 such cases have been reported since 1958, and we have reviewed these cases and discussed their clinical features, operative treatment and final outcome. The majority of these patients presented as acute surgical emergencies and a lack of awareness of this condition lead to an incorrect diagnosis in 38 per cent. Intestinal obstruction with left lung signs and a non-distended abdomen in an adult patient should arouse suspicion of this condition. A plain X-ray of the chest and contrast studies of the gastro-intestinal tract are necessary to confirm the diagnosis. A previous normal chest X-ray does not rule out a diaphragmatic hernia, as the defect may be plugged by the spleen or by the presence of a confining sac. The high incidence of strangulation emphasises the need for early diagnosis and prompt operative management which gives highly satisfactory results.

Pancreaticogastrostomy for reconstruction of pancreatic stump after pancreaticoduodenectomy for ampullary carcinoma

BACKGROUND Management of the pancreatic stump after pancreaticoduodenectomy (PD) is still a matter of debate. Pancreaticojejunostomy (PJ) is used commonly but is associated with a significant incidence of pancreatic leaks. Pancreaticogastrostomy (PG) is an alternative that has been reported to be safer. METHODS The study is a retrospective analysis of all patients having PD for ampullary carcinoma in one surgical unit at All India Institute of Medical Sciences over 18 years, with PG being the only drainage procedure for the pancreatic stump. RESULTS Among 125 patients having PD for ampullary carcinoma, overall morbidity rate was 28%, mortality rate was 4.8%, with no cases of leakage from the pancreaticogastrostomy. CONCLUSIONS In world literature (including the current series), the leakage rate of PG is 2.5% (14 of 553) with only 2 deaths (2 of 14) due to leakage from PG. Our large experience and these data conclusively prove the safety of pancreaticogastrostomy, which should be the drainage procedure of choice for the pancreatic stump following pancreaticoduodenectomy.

Cholesterol and pigment gallstones in northern India. A prospective analysis.

Two hundred one consecutive patients with gallstone disease who had undergone cholecystectomy were analyzed to determine the relative frequency of occurrence of cholesterol and pigment gallstones and to identify distinguishing features of the two stone types. Cholesterol stones (CS) formed the majority (94%) of gallstones. There were no distinctive clinical, biochemical, or radiological features of CS or pigment stones (PS). However, CS were found significantly more often than PS (P<0.05) in multiparous women leading a sedentary life-style. Although multiplicity of gallstones was somewhat commoner with CS (P<0.05) and radiopacity with PS (P<0.05) as compared with the other stone type, these differences were certainly not discriminatory between CS and PS.

Laparoscopy in primary carcinoma of the gallbladder

Fifty-three patients with suspected gallbladder carcinoma underwent ultrasonography and laparoscopy. Laparoscopy correctly excluded malignancy in five patients when ultrasonography had suggested gallbladder neoplasia. Of 48 patients with gallbladder carcinoma, laparoscopy identified 46 (95.8%) as compared with 30 (62.5%) by ultrasonography (p less than 0.001). Distant metastases in the liver, parietal peritoneum, or omentum were present in 41 patients (85.4%) and were detected by laparoscopy in 39 (sensitivity 95%) and by ultrasonography in 21 (sensitivity 51.2%) (p less than 0.001). Combination of ultrasonography and laparoscopy improved the overall diagnostic accuracy to 100%. Laparoscopy provided histological diagnosis of the disease in 36 patients (75%) and circumvented unnecessary laparotomy in 40 (83.3%) patients by revealing advanced or associated disease. When laparoscopy suggested that the disease was localized, the diagnosis was correct in 83.3% (5 of 6) patients. Laparoscopy under local anesthesia is useful in the diagnosis and staging of gallbladder carcinoma, and therefore helpful in planning management.

Dietary habits of gallstone patients in Northern India : a case control study

Dietary intake and plasma lipids were estimated in 200 patients with gallstones and 98 control subjects from a hospital in Northern India and were matched for age, sex, and social class. The intake of total calories and carbohydrates and the plasma triglyceride values were higher in all gallstone patients as compared with controls (p < 0.05 and p < 0.01, respectively). The dietary intake of refined carbohydrates was higher than in controls, but only in the female patients with gallstones (35.6 +/- 32.9 g/day compared with 24.5 +/- 11.8 g/day; p < 0.001). By contrast, the male patients with gallstones had an increased intake of fat (patients 79.0 +/- 38.1 g/day vs. controls 60.2 +/- 24.3 g/day; p < 0.05) and had increased plasma cholesterol values (patients 166.4 +/- 54.2 mg/dl vs. controls 140.3 +/- 32.8 mg/dl; p < 0.01). Such sex differences in the dietary intake and plasma lipid values may form a special feature of gallstone disease in Northern India and should be studied further.

Multicentric liposarcoma: report of two cases.

We present herein two unusual cases of multicentric liposarcoma which highlight the problems associated with the management of this disease entity. When the surgeon is confronted with multicentric liposarcomas, it is necessary to define whether they are secondary tumors or independently arising multicentric liposarcomas, since the latter situation merits a more aggressive approach. Guidelines for this differentiation are suggested in the discussion following the case reports. Surgery, which is often multiple, remains the mainstay of treatment, although adjuvant chemotherapy and radiotherapy are also usually required.

The prognostic significance of ploidy analysis in operable breast cancer

The nuclear DNA content of 98 operable breast cancers was determined by flow cytometric analysis using paraffin‐embedded tissue. All patients were on follow‐up and failure of treatment or recurrences were identified. DNA ploidy data in the form of ploidy status and DNA index (DI) has been correlated with various clinical and histopathologic factors. The only significant correlation using univariate analysis exists between the histologic grade and DI (P < 0.025), recurrence of the disease and ploidy status (P < 0.005), and recurrence of the disease and DI (P < 0.005). The absence of correlation of ploidy status with other tumor derived factors indicates the independent nature of ploidy as a prognostic factor. Multivariate analysis showed that in the whole‐group ploidy (P < 0.01), tumor margin (P < 0.01), and menopausal status (P < 0.01) were significant factors in the order mentioned. DI with a cut of at 1.29 is not found to be a significant factor in the multivariate analysis. The maximum prognostic value of ploidy status was observed in the postmenopausal group (P < 0.0005). In the node‐negative group ploidy status (P < 0.05) is the only independent significant factor predicting for early relapse. It is concluded that ploidy status is an independent prognostic factor predicting for recurrence of the disease. In the node‐negative subgroup this could be used to identify the subset of patients who may benefit from adjuvant treatment. Cancer 68:2612–2616, 1991.

Laparoscopy in carcinoma of the gallbladder

Twenty-three patients with gallbladder carcinoma were critically evaluated by laparoscopy. The diagnosis was confirmed in each case by either histology, cytology, or laparotomy. Direct evidence of carcinoma was present in 15 (65%) and indirect in eight (35%) patients. Cytology alone was positive in 80%, biopsy alone was positive in 60%, and the two techniques in combination yielded tissue diagnosis in 86% of patients having direct evidence. The yield of positive biopsy or cytology was low in cases with indirect evidence. Laparoscopy also circumvented laparotomy in 39% of patients because of the finding of multiple metastatic lesions over the liver surface.
