The clinical spectrum of splenic infarction.

Two recent cases of splenic infarction of unusual cause stimulated a review of our experience with this condition. We conducted a retrospective chart review of selected patients with pathologic diagnosis of splenic infarction seen at a large metropolitan private teaching hospital during the past 30 years. Variables analyzed included sex, age, etiology of infarction, underlying diseases, diagnostic tests, splenic pathology, and complications. Splenic infarction occurred in 59 patients (33 male and 26 female; average age, 55 years; range, 2-87 years). Etiologies included hematologic disorders (n = 35), thromboembolic disorders (n = 17), and other diseases (n = 7). Symptoms were present in 69 per cent of the patients and included abdominal pain, fever and chills, and constitutional symptoms; 18 patients were asymptomatic. Patients with nonmalignant hematologic conditions were often asymptomatic (55%); abdominal pain was common in all groups, and fever was especially common in patients with embolic conditions (70%). CT scan was the most frequent radiologic study. Patients with hematologic conditions usually were explored for complications of those conditions (69%), while complications of splenic infarction were a frequent indication for operation in patients with emboli (60%). Overall morbidity was 36 per cent, with pulmonary complications most frequent, and mortality was 5 per cent. We conclude that splenic infarction must be suspected in patients with known hematologic or thromboembolic conditions who develop left upper quadrant pain and signs of localized or systemic inflammation. CT scan is currently the preferred diagnostic test, but ultimate diagnosis depends on pathologic examination of the spleen. Surgical complications of splenic infarction include abscess and rupture.

Continuing hazards of the learning curve in laparoscopic cholecystectomy.

Bile duct injury is one of the most serious complications of laparoscopic cholecystectomy (LC). In open cholecystectomy (OC) the reported incidence of injury is less than 0.2 per cent. In LC, the aggregate reported experience, in many thousands of cases, is three or four times this number. Although "the learning curve" has been considered the principal factor in the heightened incidence of this complication with LC, there are hazards inherent in this new surgical modality that may never allow elimination of the increased risk of bile duct injury. As a sequel to an earlier report of 1200 cases of OC before the laparoscopic era from a single institution, this report deals with the next 2427 consecutive cases of LC from the same institution. In the first 1284 cases of LC, there were seven bile duct injuries (0.58%); in the ensuing 1143 cases there were six bile duct injuries (0.50%). The overall incidence nationwide is even higher, as evidenced by widespread reports of repair of bile duct injuries referred to major tertiary care centers. Routine operative cholangiography is of the utmost importance in the early recognition and immediate repair of ductal injuries. In 12 of the 13 cases reported here, early recognition and repair during the primary surgery resulted in a successful outcome.

Laparoscopic management of common bile duct stones. A multi-institutional SAGES study. Society of American Gastrointestinal Endoscopic Surgeons.

Laparoscopic common bile duct exploration (CBDE) was the subject of a multi-institutional study on 226 patients from 19 major hospital centers. Female patients predominated (2.3:1); the average age was 54; 75% of cases were chronic, and the remainder were acute. Although 97% had preoperative ultrasonograms, only 12% showed a stone in the dilated common bile duct. The alkaline phosphatase was elevated in 41% and the serum bilirubin in 28% of cases. Preoperative endoscopic retrograde cholangiography with sphincterotomy (ERC-ES) was performed in 8.5%; there was a successful stone extraction in less than half the cases. Cholangiography was performed in 99.5%, and in 94% of those cases, stones were found. In 83% of cases, stones were removed through the transcystic approach, and in 17% removal was throughout the CBD. In the majority of cases, the choledochoscope and wire basket (34%), irrigation (33%), or a combination of both was employed. In the transcystic group, 5% were converted to open procedures due to technical difficulty, as contrasted with the trans-CBD route, where the conversion rate was 19%. There were two ductal injuries. Minor complications occurred in 5.7% within 24 h; there was one death (0.4%). Within 30 days, the morbidity rate was 7% and there were no deaths. Retained stones were discovered in 2.6% of cases. Laparoscopic CBDE is a feasible approach for CBD stones which permits a definitive procedure in one stage, without pre- or postoperative ES. It is a skill which should be mastered by the biliary surgeon. Further improvement in instrumentation and technique should make the laparoscopic approach not only comparable but preferable to the standard open choledocholithotomy.

Subtotal splenectomy for Gaucher's disease: a follow-up study.

Three patients with Gaucher's disease who underwent partial splenectomy have been followed for 3, 7 3/4, and 8 1/2 years. All have had significant regrowth of the the splenic remnant and some recurrence of hypersplenism. A review of all previously reported cases also substantiates the recurrence of splenomegaly and hypersplenism. Among new options for the therapy of Gaucher's disease, enzyme replacement therapy (Ceredase) holds great promise for effective treatment.

The enigma of leiomyoblastoma: spectrum of a rare gastric tumor.

Leiomyoblastoma is a rare, smooth muscle tumor of the stomach occurring chiefly in the antrum in patients between the fifth and seventh decades. The clinical spectrum, as illustrated in eight patients described in this report, ranges from an incidental finding to a highly malignant, metastasizing neoplasm. Although the large majority of leiomyoblastomas are benign, malignancy has been reported to occur in up to 12% of cases. Resection of the tumor with an appropriate full thickness segment of gastric wall is mandatory.
