Laparoscopic versus open appendectomy: what is the real difference? Results of a prospective randomized double-blinded trial.

BACKGROUND: The comparison of laparoscopic to open appendectomy has been reviewed in many retrospective and prospective studies. Some report shorter hospital stays, less postoperative pain, and earlier return to work while others fail to demonstrate such differences. We performed a prospective, randomized double-blinded trial to evaluate this ongoing debate. METHODS: Fifty-two consecutive men presenting with signs and symptoms suggestive of acute appendicitis were randomized to undergo either laparoscopic appendectomy or open appendectomy. Length of operative times, hospital stay, lost work days, visual analog pain scores, and operative costs were compared. RESULTS: Length of stay averaged 21.5 h for the laparoscopic group and was not statistically different when compared to the open group. Perceived postoperative pain on postoperative days 1 and 7 were not statistically different between the two groups. Mean time to return to work was 11 days, and there was no statistical difference between groups. Operative costs were >600 dollars greater for the laparoscopic approach. CONCLUSIONS: In this prospective randomized double-blinded trial, laparoscopic appendectomy appears to confer no significant advantage over open appendectomy for postoperative pain or lost work days. It does carry an increase in operating room costs and, contrary to other reports, hospital stay is not shortened. Further studies are needed to determine if specific populations, such as the obese or women, may benefit from a minimally invasive approach to appendicitis.

Surgical wound morbidity in an austere surgical environment.

Surgical wound morbidity was analyzed for a U.S. military field hospital deployed to the Republic of Haiti in support of Operation New Horizons 1998. The purpose of the analysis was to determine if procedures performed in the field hospital had greater infectious risks as a result of the environment compared with historical reports for traditional hospital or clinic settings. Acceptable historical infection rates of 1.5% for clean surgical cases, 7.7% for clean contaminated cases, 15.2% for contaminated cases, and 40% for dirty cases have been noted. There were 827 operations performed during a 6-month period, with the majority of patients assigned American Society of Anesthesiologists Physical Status Classification class I or II. The distribution of these cases was: 72% clean cases, 5% clean contaminated cases, 4% contaminated cases, and 19% dirty cases. The overall wound complication rate was 3.6%, which included 5 wound infections, 11 wound hematomas, 8 superficial wound separations, and 6 seromas. The infectious morbidity for clean cases, the index for evaluation of infectious complications, was 0.8%, well within the accepted standards. There were two major complications that required a return to the operating room: a wound dehiscence with infection in an orchiectomy, and a postoperative hematoma with airway compromise in a subtotal thyroidectomy. There were no surgical mortalities. The infectious wound morbidity for operations performed in the field hospital environment was found to be equivalent to that described for the fixed hospital or clinic settings. No special precautions were necessary to ensure a low infection rate. The safety for patients undergoing elective surgical procedures has been established. Further training using these types of facilities should not be limited based on concerns for surgical wound morbidity.

Spontaneous hemoperitoneum.

Massive hemoperitoneum seen without an obvious precipitating event is rare. A 21-year-old man was seen with diffuse abdominal pain of 48 hours' duration. He had no fever, nausea, or vomiting, and most laboratory values were normal. Exploration of the abdomen revealed free intraperitoneal blood with clotting but failed to reveal a source. The patient could recall no trauma or other inciting event. The only abnormalities found during laparotomy were multiple adhesions of the omentum to the lateral abdominal wall and localization of most of the clot within the greater omentum. The author cautions that a high index of suspicion followed by laparotomy are the management tools for controlling spontaneous hemoperitoneum. Conservative management produces a high mortality rate.

Anal duct carcinoma: report of case and a survey of the experience of the American Osteopathic College of Proctology.

Anal duct carcinoma, also known as anal gland carcinoma or adenocarcinoma of the anal canal, is an unusual anal cancer that accounts for approximately 0.1% of all gastrointestinal cancers. Delays in diagnosis most likely account for the poor prognosis associated with this cancer. Presenting symptoms often mimic those of more common benign anorectal pathologic processes. Multimodality treatment that includes surgery, chemotherapy, and radiation therapy is often recommended. The authors describe a typical case of anal duct carcinoma and its management. They also discuss the findings of a survey of the combined experience of members of the American Osteopathic College of Proctology and review the literature.

Value of carcinoembryonic antigen monitoring in curative surgery for recurrent colorectal carcinoma.

PURPOSE: This study is designed to review a carcinoembryonic antigen (CEA)-driven postoperative protocol designed to identify patients suitable for curative reresection when recurrent colorectal cancer is identified. METHODS: A total of 285 patients who were operated on for colon or rectal carcinoma between 1981 and 1985 were evaluated (with CEA levels) every two months for the first two years, every three months for the third year, every six months for years 4 and 5, and annually thereafter. CEA levels above 5 microg were considered abnormal and were evaluated with diagnostic imaging and/or endoscopy. RESULTS: Follow-up was available for 280 patients (98.2 percent). Distribution of patients by Astler-Coller was: A, 14 percent; B1, 20 percent; B2, 39 percent; C1, 5 percent; C2, 21 percent. There were 62 of 280 patients (22 percent) who developed elevated CEA levels, with 44 patients who demonstrated clinical or radiographic evidence of recurrence. Eleven patients were selected for surgery with curative intent (4 hepatic resections, 1 pulmonary wedge resection, 2 abdominoperineal resections, 2 segmental bowel resections, and 2 cranial metastasectomies). Three of 11 patients (27 percent) benefited and have disease-free survivals greater than 60 months. Of the 223 patients without elevated CEA, 22 (9.9 percent) had recurrent cancer without any survivors. Overall, 3 of 285 patients (1.1 percent) were cured as a result of CEA follow-up. CONCLUSION: CEA-driven surgery is useful in selected patients and can produce long-term survivors.
