Perforation of a Meckel's diverticulum caused by ingestion of a coin.

A 25-year-old woman ingested a quarter. Three days later, lower abdominal pain, fever, chills, and physical findings compatible with pelvic inflammatory disease developed. Radiographic examination showed the coin in the middle pelvis. Persistent abdominal complaints, abnormal physical examination, and failure of the coin to progress through the gastrointestinal tract despite conservative management led to surgical intervention. Exploration revealed an inflammatory process in the posterior uterine culde-sac with multiple omental, small bowel, and uterine adhesions due to perforation of a Meckel's diverticulum. Excision of the Meckel's diverticulum was done, and the patient recovered satisfactorily.

Training resident surgeons in combat: an experience during the Persian Gulf War.

The Persian Gulf War necessitated the activation of many Army Reserve and National Guard physicians, including a number in residency training. No prototype existed for the continued training of resident surgeons in a combat setting. The 159th Mobile Army Surgical Hospital (MASH) deployed in support of the Allied invasion of Iraq. A structured training program for two general surgery residents attached to the 159th MASH was developed and implemented. This program combined supervised operating room experience, perioperative management, morbidity and mortality conferences, and orthopedic grand rounds, all with careful professional documentation. A planned reading program could not be realized, due to the physical setting of wartime. Residents and attending staff interacted positively and the residents were able to continue their formal training as an integral part of the hospital. The model developed by the 159th MASH is a practical method of continuing structured resident training in a combat setting.

Splenectomy for hematologic disorders: a 20 year experience.

A retrospective chart analysis was conducted for all patients undergoing splenectomy for hematologic disorders at the Baptist Hospitals of Louisville between 1970 and 1989. Fifty-nine charts comprise the basis of this review. Variables considered included disease entities treated by splenectomy, indications for splenectomy, and morbidity and mortality associated with the surgery. Additional variables evaluated were splenic weight, estimated blood loss at surgery, technique of splenectomy, and drainage of the splenic bed. The authors found a high correlation of splenic weight to the hematologic disorder treated. Larger spleens were associated with greater blood loss at surgery. Preliminary splenic artery ligation did not reduce the operative blood loss in patients with massive spleens. Drainage of the splenic bed was not associated with postoperative bleeding or intra-abdominal abscess. The low morbidity (22%) and mortality (3.4%) compares favorably to other published studies, demonstrating that splenectomy for hematologic disorders may be safely performed in the community hospital setting.

Preliminary experience with the Hutson-Russell loop cutaneous choledochojejunostomy.

In 1984, the use of a choledochojejunocutaneous fistula was described to allow balloon dilation of benign biliary strictures. Later, the use of the technique to obtain repeated access to the biliary tree in a larger series of patients was reported. The experience provided a foundation for the application of the technique in nine patients at Wilford Hall United States Air Force Medical Center. Represented were a variety of benign and malignant disorders. Six patient reports are offered from this preliminary experience to demonstrate the range of problems lending themselves to the use of the Hutson-Russell loop. Suggestions for present and future applications of the versatile choledochojejunocutaneous loop are included.

Major hepatic resection in a residency training program.

Records of 30 major hepatic resections performed at David Grant USAF Medical Center and Wilford Hall USAF Medical Center were analyzed to assess the feasibility, safety, and resources required for such procedures in a general surgery residency training program. The mean intraoperative blood loss during surgery was 2022 mL and the mean intraoperative transfusion volume was 4.2 units of packed red blood cells. Patients spent an average of 2.7 days in the intensive care unit, with a mean overall postoperative stay of 15 days. One death occurred within 30 days of operation due to a postoperative myocardial infarction, and another death during the hospital stay was due to hepatic insufficiency and Candida endocarditis. Overall, five major postoperative complications occurred (17%), one requiring reoperation. All but one procedure was done by a closely supervised surgical resident. This experience compares favorably with others in the literature and supports the practice of hepatic resection as part of surgical training.

Wound complications following modified radical mastectomy: an analysis of perioperative factors.

To assess the effect of perioperative factors on the incidence of postoperative wound complications, the authors retrospectively analyzed 101 patients who had undergone modified radical mastectomy. These factors included age, body weight, operative techniques, estimated blood loss, wound-catheter drainage, extent of axillary dissection, nodal involvement, and length of hospital stay. Complications included seroma (10.9%), wound infection (8.9%), wound necrosis (5%), hematoma (3%), lymphedema (2%), and pneumothorax (1%). The logistic regression method was used to analyze the data. When electrocautery was used to create the skin flaps, the probability of a wound complication was .462, a 44% increase over that calculated for the cold-knife technique (P = .05). A prolonged hospitalization accompanied the occurrence of a wound complication. No other factors reached statistical significance.

Endometriosis arising in abdominal incisions.

The differential diagnosis of an incisional mass arising in a female includes endometriosis. The occurrence of abdominal scar endometriosis following hysterotomy is uncommon, being reported in less than 0.5% of patients undergoing cesarean section. Three cases of this unusual problem are reported, the experience at David Grant USAF Medical Center evaluated, and pertinent literature reviewed. The principles of surgical management include obtaining an accurate diagnosis and adequate excision.

Needle-localized biopsy of occult breast lesions.

Over a 3 1/2-year period, we did 121 needle-localized breast biopsies for nonpalpable, mammographically suggestive lesions. The presence of a mass lesion on mammography with or without microcalcifications was associated with malignancy more frequently than microcalcifications alone. In 15 cases (12.4%), biopsy showed malignancy; 13 patients had modified radical mastectomy, with 11 (85%) having no histologic evidence of axillary metastases. Evaluation of risk factors associated with breast cancer in those patients with positive biopsy results showed that advanced age and a past history of a breast cancer were present in a significant number of patients. Four patients (3.5%) had complications; a hematoma developed in one (0.8%), and three (2.7%) required a second biopsy to remove the suggestive mammographic lesion. We conclude that needle-localized breast biopsy is a reliable tool in detecting early breast carcinoma. The procedure causes only minimal morbidity and we believe it should be done in all patients with mammographically suggestive, nonpalpable breast lesions.

Surgical manifestations of eosinophilic gastroenteritis in the pediatric patient.

Eosinophilic gastroenteritis, an inflammatory bowel disease of unknown etiology, occurs in one of 10,000 admissions to this Children's Hospital. We had added 4 cases to the 11 retrieved from a literature review. The inflammation is characterized by mature eosinophils predominating a transmural process which may produce pain, obstruction, perforation, bleeding, or fistulae. All levels of the gastrointestinal tract are involved, but stomach (25.9%) and small bowel (66.7%) lesions are most common. Eosinophilia occurs in 61% of children and allergy in 13%. X-rays may demonstrate a diffuse or localized process. Operative intervention may be necessary to exclude tumors or regional enteritis, and at times to extirpate complications of local disease, but conservative therapy is the treatment of choice for this exacerbating-remitting disease.
