Internal herniation through a defect in the broad ligament.

Internal hernias of a developmental nature are an uncommon cause of intestinal obstruction. Among the rarest of internal hernia is that which involves a defect in the broad ligament of the uterus. The case report of an elderly lady who had herniation of small bowel through a defect in the left broad ligament is presented.

Congenital gastric anomalies.

A review with a classification of congenital defects involving the stomach is presented. Owing to the fact that in certain lesions there are so few case reports available for study, the etiology and true nature of these defects remains unknown. It is incumbent upon the surgical community to continue to document congenital anomalies of the stomach and report them accordingly.

Congenital prepyloric web in a child.

A case of a child with an antral mucosal web is presented. The literature concerning these webs in children and adults is reviewed. Several conclusions are reached. First, the etiology of these webs in adults and children is different. Second, webs are not usually considered in a differential diagnosis of gastric outlet obstruction, and the correct diagnosis is often not made even with contrast radiography and endoscopy being employed. Thirdly, it is speculated that division of these webs via the endoscope is quite plausible.

Perforation of the intrapericardial aorta during subclavian catheterization.

We have reported a case of fatal perforation of the intrapericardial aorta during attempted subclavian venipuncture through the infraclavicular route in a patient with a ruptured ectopic pregnancy. The case illustrates the importance of having the procedure done only by personnel experienced in the technique, even in emergency situations.

Benign neurilemmoma manifesting as a presacral (retrorectal) mass: report of a case.

We recently had the opportunity to treat a patient who had a large presacral mass. The mass, a 13-cm neurilemmoma, was removed through a combined abdominosacral approach. Mostly benign, these presacral masses cause symptoms by compression of adjacent pelvic structures. Digital rectal examination generally provides the diagnosis. Although most such lesions may be removed by a Kraske procedure, large lesions may be best treated using a combined abdominosacral approach.

Ileocecal masses discovered unexpectedly at surgery for appendicitis.

During the past five years we have encountered 15 patients who were found to have an ileocecal mass of undetermined etiology when explored through a right lower quadrant incision for presumed appendicitis. Diverticulitis of the ileocecal region accounted for almost one-half of these lesions. There are many possible etiologies for mass lesions in this location, but beacuse malignancy cannot be excluded at operation, a right hemicolectomy is advised. We found that this procedure could be done with relative safety in unprepared bowel under emergency conditions.

Penetrating injuries of the appendix.

Although rare, penetrating injuries of the appendix pose an interesting finding at laparotomy. Associated penetrating gastrointestinal injuries are common. Four additional cases of trauma to the appendix from penetrating wounds are described.

Intrapericardial tumbling bullet.

Foreign bodies of the pericardium are rare and they are associated most commonly with significant trauma. The diagnosis of a pericardial foreign body can be difficult. One must distinguish between foreign matter in the cardiac chamber or free-floating in the mediastinum. Serial chest X-rays and fluoroscopy were most helpful to us. Neither CT scan nor an echocardiogram were particularly helpful. To prevent pericarditis, either sterile or non-sterile, with potential for other significant complications, removal of a pericardial foreign body is always indicated.

Isolated blunt trauma injury to the hepatic duct.

Isolated bile duct injuries are quite rare. The diagnosis may be difficult. The presence of continued abdominal pain, nausea, vomiting, distention and jaundice in addition to abnormal liver function tests and often a leukocytosis mandate that a biliary tract injury be ruled out. The most important diagnostic study for confirming a biliary tract injury is paracentesis. The ERCP is then done to delineate the anatomy of the injury. Transhepatic cholangiography is an alternative to the ERCP. Treatment for a biliary duct injury must be selected on an individual basis.

Merkel cell tumor: two cases.

Merkel cell tumors are rare skin lesions that arise from the Merkel cell in the dermal layers. The two cases presented in this report are important in that they add more information to the literature than previously had been recognized. The first case discusses a collision tumor with a basal cell carcinoma. This is the first such report of this type of collision tumor. The second report is of a black female with a Merkel cell tumor of her finger. The case is unusual in that it is only the second time that a black female is reported to have this disease and the first time that it is reported on a digit. A review of the literature accompanies these case reports.
