Four cases of pneumatosis cystoides intestinalis following ileojejunal by-pass in 37 patients are described and the literature reviewed. This complication is usually a self-limited condition, responding to conservative management.
Benign non-parasitic cysts of the spleen are very uncommon, with a total of 651 cases having been described in the literature to date. Because of their uncommon nature, and the fact that their symtoms may be vague, a high index of suspicion is necessary if they are to be diagnosed. The therapy of choice is surgical excision by splenectomy and the accompanying cystectomy. The prognosis following such therapy is excellent.
This is the first reported case of mumps hemorrhagic pancreatitis in a child, documented at operation, and by rising mumps titers and complicated by a pseudocyst. In severe cases when surgery is indicated, drainage of the lesser sac usually prevents pseudocyst formation. If a pseudocyst occurs, drainage is required to eliminate disabling pain and chronic pancreatitis. Live attenuated mumps vaccine may eliminate this source of pancreatitis from American children in the future.

The impact of laparoscopic cholecystectomy (LC) on the operative experience of surgical residents was assessed in a series of 787 cholecystectomies. During an initial 18-month period, residents participated in LC as operating surgeon and as first assistant or camera operator in 33% and 97% of cases, respectively. Operative time, cholangiography rate, conversion rate, and complications were not adversely affected by resident operators. Residents performed 87% of concurrent planned open cholecystectomies (OC). In comparison to the 6 months preceding LC: (1) The mean number of resident OCs decreased significantly while the total number of resident cholecystectomies was unchanged; (2) the proportion of OCs performed by PGY5 residents significantly increased at the expense of junior resident cases. LC can be safely integrated into surgical resident training by standard methods as for open procedures. Although resident operative experience has been redistributed, initial experience does not suggest that qualification in open biliary surgery has been compromised.
