ObjectiveThe authors compare open and laparoscopic appendectomy in a randomized fashion with regard to length of operation, complications, hospital stay, and recovery time. MethodsAdult patients (older than 14 years of age) with the diagnosis of acute appendicitis were randomized to either open or laparoscopic appendectomy over a 9-month period. All

Diagnostic peritoneal lavage (DPL) and computed tomography (CT) are the primary diagnostic modalities used in the evaluation of patients with suspected blunt abdominal trauma (BAT). DPL is fast and accurate but is associated with complications. CT is also accurate, yet requires stability and transportability of the patients. Ultrasound (US) has been suggested as an aid in evaluating BAT. We evaluated US in the initial assessment of BAT in 1000 patients. Patients were eligible for the study if they met specified trauma criteria and had suspected BAT. We then followed the outcome of the patients and their further work-up. US showed a sensitivity of 88%, a specificity of 99%, and an accuracy of 97% for detecting intraabdominal injuries. We conclude that emergency ultrasound may be used as the initial diagnostic modality for suspected blunt abdominal trauma.

Increasingly, patients of advanced age are coming for evaluation of periampullary tumors. Although several studies have demonstrated the safety of resecting periampullary tumors in older patients, few long-term survival data have been reported. Between 1983 and 1992 various periampullary masses were resected in 70 patients over age 65 (range 65-87 years). Total pancreatectomy was performed in 11 patients, and 59 patients underwent pancreaticoduodenectomy. The mean duration of hospitalization was 17 +/- 15 days. Major complications occurred in 27 patients (39%), and operative mortality rate was 8.5%. Overall median survival was 24 months; and 5-year survival was 25%. Perioperative outcome was compared in patients aged 65 to 74 years and in patients > or =75 years old. The older age group required longer periods in the surgical intensive care unit postoperatively, but the long-term survival was similar in the two age groups. Radical resection with the intent to cure periampullary tumors is safe in selected patients of advanced age, and long-term survival is in the range of expected survival for younger patients with the same tumors.

ObjectiveTo determine the optimal method of wound closure for dirty abdominal wounds. Summary Background DataThe rate of wound infection for dirty abdominal wounds is approximately 40%, but the optimal method of wound closure remains controversial. Three randomized studies comparing delayed primary closure (DPC) with primary closure (PC) have not conclusively shown any advantage of one method over the other in terms of wound infection. MethodsFifty-one patients with dirty abdominal wounds related to perforated appendicitis, other perforated viscus, traumatic injuries more than 4 hours old, or intraabdominal abscesses were enrolled. Patients were stratified by cause (appendicitis vs. all other causes) and prospectively randomized to one of two wound management strategies: E/DPC (wound packed with saline-soaked gauze, evaluated 3 days after surgery for closure the next day if appropriate) or PC. In the E/DPC group, wounds that were not pristine when examined on postoperative day 3 were not closed and daily dressing changes were instituted. Wounds were considered infected if purulence discharged from the wound, or possibly infected if signs of inflammation or a serous discharge developed. ResultsTwo patients were withdrawn because they died less than 72 hours after surgery. The wound infection rate was greater in the PC group than in the E/DPC group. Lengths of hospital stay and hospital charges were similar between the two groups. ConclusionA strategy of DPC for appropriate dirty abdominal wounds 4 days after surgery produced a decreased wound infection rate compared with PC without increasing the length of stay or cost.Dirty surgical wounds are associated with a high rate of wound infection.1 Postoperative wound infections have a significant impact on health resources and costs, 2,3 and the sequelae of wound infections (wound dehiscence and resulting incisional hernias) can result in significant long-term problems. 4 -6 Of the many risk factors influencing postoperative wound infections, the method of skin closure has been implicated as an important factor. Delayed primary closure (DPC) and primary closure (PC) are two commonly used methods, but there is no consensus as to the optimal method. Cruse and Foord 1 found in a retrospective survey a wound infection rate of 40% among 2,093 dirty wounds, but they did not specify how skin closure was performed. Three prospective randomized studies 7-9 performed on appendectomy wounds only showed no advantage to DPC in terms of decreased wound infection compared with PC. We conducted a prospective randomized trial on patients with dirty abdominal wounds and hypothesized that a strategy of DPC of appropriate dirty abdominal wounds would result in a decreased rate of wound infection.

Laparoscopically assisted Hartmann's reversal results in comparable morbidity, but may be associated with shorter hospital stay when compared with laparotomy.
