Abstract
BACKGROUND Strategies for the management of patients with necrotizing pancreatitis remain controversial. While consensus opinion supports operative necrosectomy for the treatment of infected pancreatic necrosis, the timing for surgical intervention is not completely resolved. Further, the indication for the surgical management of sterile pancreatic necrosis is also subject to debate. METHODS The objective of this study was to evaluate outcome measures for the surgical management of necrotizing pancreatitis, independent of documented infection. A retrospective review was undertaken between 1994 and 2002 at a single county hospital. RESULTS Twenty-one patients with CT-documented necrotizing pancreatitis underwent operative pancreatic necrosectomy with laparostomy within 21 days of initial diagnosis and had an average of three reoperations. Average length of stay (LOS) in the ICU was 36 days and in the hospital 67 days. Ten patients had documented infected necrosis based on initial intra-operative cultures, while I I had sterile necrosis. Overall, 95% (20/21) of the patients had a complication, with an average of three complications per patient. Common complications included ARDS (71%), sepsis (33%), renal failure (24%), and pneumonia (24%). The overall mortality rate was 14% (3/21), with a mean follow-up of 469 days. DISCUSSION The surgical management of acute necrotizing pancreatitis, independent of documented infection, can be undertaken within 3 weeks of diagnosis with an acceptable morbidity and a low mortality rate. Creation of a laparostomy to enable ready, atraumatic debridement of the retroperitoneum is a safe alternative to standard repeat laparotomies and thus represents a useful adjunct to the surgical management of necrotizing pancreatitis.

Tracheal-innominate artery fistula caused by the endotracheal tube tip: case report and investigation of a fatal complication of prolonged intubation. Respir Care 2001; 46:1012-8.

Abstract
CASE REPORT A patient with extensive burns was intubated with an 8.0 mm internal diameter endotracheal tube (ETT) equipped with a subglottic suction port (Mallinckrodt HiLo Evac). The ETT was secured to a left upper molar with wire sutures throughout the hospitalization course to ensure airway stability. On the 40th day of intubation, the patient exsanguinated and died from a tracheo-innominate artery fistula. Postmortem examination revealed a 1 cm lesion of the left anterior tracheal wall at the position of the ETT tip. The prolonged stationary position of the ETT was considered the primary factor responsible for the fistula. Yet tracheo-innominate artery fistula normally is associated with high cuff pressures rather than with the tube tip. The special ETT construction required for the subglottic suction feature was suspected to have increased tube rigidity and may have played a contributory role. METHODS The rigidity of the Mallinckrodt HiLo Evac was measured with a mechanical model and compared to 5 other commercially-available ETTs. Rigidity was expressed as the force generated by the ETT tip when the tube curvature was altered by 5 cm and 10 cm of flexion from its resting position. RESULTS The mean force exerted by the Mallinckrodt HiLo Evac was 10.1 +/- 2.8 g at 5 cm of flexion and 17.7 +/- 5.1 g at 10 cm of flexion. This was significantly greater than all other ETT brands tested (by one-way analysis of variance and Student-Newman-Kuels test, p < 0.05). CONCLUSION This case of fatal tracheo-innominate artery fistula formation associated with an ETT tip was unusual because of the extended duration of endotracheal intubation and the complexity of the patient's airway management problems. Our data suggest that the higher rigidity of the HiLo Evac ETT may have contributed to fistula development at the tube tip. However, we do not believe that the higher rigidity of the HiLo Evac ETT necessarily poses any greater risk than other ETTs under normal circumstances, in which the tube tip is not fixed in a stationary position for an extended period.

Abstract
HYPOTHESIS Cinematic technetium Tc 99m red blood cell ((99m)Tc-RBC) scans, in which real-time scanning is performed and analyzed, can accurately localize gastrointestinal bleeding and thus direct selective surgical intervention. DESIGN Retrospective medical record review with historical controls. SETTING Large, university-affiliated public hospital in urban setting. PATIENTS Twenty-six patients presenting with upper and lower gastrointestinal hemorrhage who underwent cinematic (99m)Tc-RBC scan examinations between 1990 and 1997 and required surgical intervention to control the bleeding. INTERVENTIONS All patients with gastrointestinal bleeding underwent open surgical procedures to provide cessation of bleeding and resection of appropriate abnormalities. MAIN OUTCOME MEASURES Patient outcome was based on correlation between preoperative RBC scans and intraoperative findings, surgical pathology, and postoperative clinical course. RESULTS Twenty-five (96%) of 26 scans were interpreted as positive for gastrointestinal bleeding. In 22 of these 25 scans, the site of bleeding was correctly identified for a sensitivity of 88%. One or more additional diagnostic tests were performed on 19 (73%) of 26 patients, and included angiography and flexible endoscopy. The most common operation performed to control bleeding was a hemicolectomy (14/26). Diverticulosis was the most prevalent diagnosis (46%). Two patients (8%) experienced rebleeding after operation. The overall mortality rate was 19% (5/26). CONCLUSIONS Cinematic (99m)Tc-RBC scintigraphy is a sensitive, noninvasive alternative to mesenteric angiography for accurately localizing the site of gastrointestinal hemorrhages. As such, this technique can be reliably used to direct selective surgical intervention.

Abstract
HYPOTHESIS That the clinical presentations, biochemical profiles, and surgical outcomes of patients treated with laparoscopic vs open adrenalectomy for primary hyperaldosteronism are different. DESIGN, SETTINGS, PATIENTS, AND INTERVENTIONS: The medical records of 80 patients with primary hyperaldosteronism who underwent open adrenalectomy between 1975 and 1986 or laparoscopic adrenalectomy between 1993 and 1998 at the University of California-San Francisco were reviewed by a single unblinded researcher (W.T.S.). MAIN OUTCOME MEASURES Severity of hypertension and hypokalemia at diagnosis, their improvement after adrenalectomy, and operative complications. RESULTS Thirty-eight patients underwent open adrenalectomy and 42 patients underwent laparoscopic adrenalectomy. The patients who underwent open adrenalectomy had documented hypertension for a median of 5 years before surgery; all had diastolic blood pressures greater than 100 mm Hg. Laparoscopically treated patients had documented hypertension for a median of 2.5 years preoperatively, and 20 (48%) had diastolic blood pressures greater than 100 mm Hg. The median preoperative serum potassium levels for the open and laparoscopic groups were 2.6 mmol/L and 3.3 mmol/L, respectively; the mean serum aldosterone levels were 1.47 nmol/L and 1.30 nmol/L. Thirty-two (84%) of the 38 patients who underwent open surgery and 41 (98%) of the 42 patients treated laparoscopically had adrenal adenomas. The sensitivity of preoperative computed tomographic scanning for adenomas was 83% for the patients treated with open adrenalectomy and 93% for those treated laparoscopically. There were 4 postoperative complications in the open surgery group and none in the laparoscopic group. Postoperatively, 30(81%) of 37 patients (excluding 1 patient who died of adrenocortical carcinoma) in the open surgery group and 37 (88%) of 42 patients treated laparoscopically were normotensive. Post-operative values were 3.6 to 5.0 of serum potassium per liter and 3.5 to 4.9 of serum potassium per liter in the open and laparoscopic groups, respectively. CONCLUSIONS Patients who are treated with laparoscopic adrenalectomy for primary hyperaldosteronism are being referred with less severe hypertension and hypokalemia than patients formerly treated with open adrenalectomy. Patients treated laparoscopically had fewer postoperative complications and were equally likely to improve in blood pressure and hypokalemia. Laparoscopic adrenalectomy has become the treatment of choice for patients with primary hyperaldosteronism because of lower morbidity.

Leukocytosis and free fluid are important indicators of isolated intestinal injury after blunt trauma. THE JOURNAL OF TRAUMA 1999; 46:656-9.

Abstract
BACKGROUND The detection of isolated intestinal injuries after blunt trauma can be difficult because of subtle signs and symptoms, often leading to delayed diagnosis. We hypothesized that specific clinical indicators could be identified to assist in the diagnosis of these injuries. METHODS Medical records of all patients with such injuries from 1988 to 1996 were reviewed. The patients were stratified into those operated on within 6 hours of presentation (apparent injury) and those operated on after 6 hours (occult injury), and the data were compared. RESULTS Forty-six patients with isolated intestinal injuries were identified. There were no differences in the rate of peritonitis or free fluid on abdominal computed tomography, blood loss, intraoperative findings, or morbidity and mortality between groups. Leukocytosis (sensitivity, 84.8%; specificity, 55.2%; p = 0.01) and free fluid on computed tomography were frequently present, however, and their significance was underappreciated in the occult injury group. CONCLUSION After blunt abdominal trauma in patients without obvious indications for invasive evaluation of the abdomen (e.g., peritoneal lavage, laparoscopy, laparotomy), leukocytosis can indicate an intestinal injury. Additionally, unexplained free fluid on abdominal computed tomography must be aggressively evaluated.

Abstract
OBJECTIVE To assess factors that might predict serious necrotizing soft tissue infections following illicit drug injection. DESIGN A retrospective review of a consecutive case series. SETTING An urban municipal hospital. PATIENTS Thirty patients presenting with cutaneous abscesses resulting from illicit drug injections during a 5-year period. All cases presented clinically with fluctuance, erythema, or induration but required extensive debridement at the time of incision and drainage. INTERVENTIONS Operative treatment employed wide incision, routine subfascial examination, and aggressive debridement. Clinical management included broad-spectrum antibiotics, critical care support, and reconstructive procedures. MAIN OUTCOME MEASURES Mortality, extent of debridement, preoperative vital signs and laboratory values, Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, bacteriologic and pathologic test results. RESULTS Postoperatively, all patients were housed in the intensive care unit for 8.4 +/- 14.5 days. Six patients died (20%). On arrival at the intensive care unit, systolic blood pressure was 80 mm Hg or less in 2 patients, 1 of whom died. White blood cell count on hospital admission was elevated in 27 of 30 patients (mean, 27.2 +/- 15.3 x 10(9)/L) and 2 patients were identified as having human immunodeficiency virus infection. All patients underwent initial surgery less than 24 hours after admission; following debridement, the average wound size was 276 +/- 238 cm2 (range, 15-783 cm2). Five patients required extremity amputation, and all other survivors underwent reconstruction with skin grafts and/or myocutaneous flaps. All but 1 patient were reexamined in the operating room within 12 hours and underwent an average of 3.1 +/- 1.6 operative procedures. Of those wound cultures obtained in the operating room, there was no pattern to the bacteriologic isolates. Seventeen patients had mixed isolates and 11 had single organisms. Pathologic findings in 20 patients included panniculitis (3 patients), necrotizing fasciitis (11 patients), myositis (6 patients), and osteomyelitis (1 patient). We failed to identify any clinical factor, including temperature, heart rate, systolic blood pressure, white blood cell count, base deficit, albumin level, PO2, or APACHE II score that could predict mortality or the requirement for extensive debridement. CONCLUSIONS Parenteral injections of illicit drugs can produce infections that present with signs of simple cutaneous abscess and yet unpredictably become extensive necrotizing soft tissue infections. Treatment requires a high index of suspicion along with an inquisitive operative approach to avoid missing these potentially serious infections.

Abstract
BACKGROUND Recurrent pyogenic cholangitis is a complex biliary tract disease characterized by intrahepatic pigment stones, endemic to Southeast Asia and seen with increasing frequency in the United States. The purpose of this study was to review the management of this disorder in a county hospital. METHODS A retrospective review of 45 patients with recurrent pyogenic cholangitis evaluated between 1984 and 1995. The clinical and surgical management of patients with localized versus bilateral hepatolithiasis were compared. RESULTS The prevalence of recurrent pyogenic cholangitis at our hospital has more than doubled since 1983. Fourteen of 45 patients (31%) had bilateral disease and required more abdominal computed tomography scans (P < 0.01), percutaneous cholangiograms (P < 0.05), endoscopies (P < 0.01), clinic visits (P < 0.05), and hospital admissions (P < 0.02) as compared with patients with localized disease. CONCLUSIONS The effective treatment of recurrent pyogenic cholangitis requires definition of the patients' intrahepatic distribution of disease, prior to surgical intervention, and the coordinated efforts of gastroenterologists, radiologists, and surgeons.

Abstract
Determining the perioperative risks associated with surgical procedures performed in patients with HIV disease is a difficult and complex task. Because HIV is a contagious, blood-borne pathogen, it threatens the health and well-being of both patient and health care provider. Despite poor early results, there is now convincing evidence that HIV infection is not a significant, independent risk factor for major surgical procedures. In practice, the authors evaluate the risk of surgery in patients with HIV infection using the same basic tools and guidelines applied to the uninfected, with the best predictors of surgical morbidity and mortality stemming from a careful and accurate assessment of the patient's cardiopulmonary, renal, endocrine, and nutritional reserve. Although HIV disease provides a unique constellation of diagnoses and challenges to the health care provider, the risk of major surgery in this population is not unlike that for other immunocompromised or malnourished patients. The authors believe that members of the surgical team have a professional, moral, and ethical responsibility to provide the highest possible quality of care for their patients, regardless of their HIV status. If after weighing the risks and benefits to the patient the surgeon believes the procedure will have a positive effect on the patient's life, the surgeon must offer surgical treatment. To do less does a disservice to the patient, the provider, and the profession as a whole.

Abstract
OBJECTIVE To compare the lateral transabdominal and posterior retroperitoneal laparoscopic methods for performing adrenalectomy. DESIGN Nonrandomized. SETTING Hospitals affiliated with the University of California, San Francisco. PATIENTS Thirty-six patients (15 men and 21 women), aged 5 to 78 years (mean age, 49 years), were treated for the following conditions: aldosteronoma, 18 patients; pheochromocytoma, 4 patients; Cushing syndrome, 6 patients; androgen-secreting tumor, 1 patient; nonfunctioning adenoma, 3 patients; adrenal hemorrhage, 1 patient; metastatic neoplasm, 2 patients; and myelolipoma, 1 patient. INTERVENTIONS Twenty-three lateral and 14 posterior laparoscopic adrenalectomies. MAIN OUTCOME MEASURES Success rate, operating time, complications, and length of hospital stay. RESULTS The tumors, which ranged in size from 1 to 13 cm (mean, 4.2 cm; median, 2.5 cm), were all successfully resected laparoscopically. All 8 tumors larger than 6 cm were resected by the lateral approach. One critically ill patient died. No patient required blood transfusions or conversion to laparotomy. Mean operating time was 3.8 hours vs 3.4 hours (median, 3.5 hours vs 3 hours) and mean hospital stay was 2.2 days vs 1.5 days (median, 2 days vs 1 day) for the lateral and posterior approaches, respectively. All patients without concomitant procedures were ready to be discharged within 48 hours. CONCLUSIONS Both approaches were effective and safe. We prefer the lateral approach for tumors larger than 6 cm and the posterior approach for bilateral tumors.

Abstract
In concluding whether universal precautions are necessary, it certainly appears that we need something to reduce the significant problem of HIV transmission to health-care providers. As occupational risk goes, it exceeds the occupational risk of a number of other high-risk professions. Unfortunately, we do not know if universal precautions are effective. We also do not know the true compliance rate in use of universal precautions, nor whether they have an impact on transmission even if effectively used. What are the alternatives? They are not great, but some have not been adequately explored or implemented. Re-engineering around needle use in the hospital is clearly the most likely area to produce concrete results, because needlesticks are overwhelmingly the greatest source of infection, but this has not been encouraged to the degree it could be, even with systems already developed. Universal testing does not appear to be a viable alternative, for numerous reasons already discussed. Finally, are universal precautions more important for other pathogens than HIV? I would say yes. Hepatitis B, hepatitis C, and nosocomial infections are more important both as public health issues and as health-care provider prevention issues. If universal precautions are effective in reducing any of these, they are worthwhile.

Abstract
Health care reform will affect the relationship of trauma centers to health maintenance organizations and other managed care plans. We studied Kaiser Permanente Medical Center (Kaiser) members admitted to the Trauma Center at San Francisco General Hospital (SFGH) to determine: (1) variables predicting transfer from SFGH to a Kaiser Hospital (repatriation), (2) the length of hospital stay (LOS), and (3) the cost of their care. The SFGH trauma registry provided data on 7,794 patients admitted before 1994. To investigate LOS, 89 Kaiser patients over 1 year were matched with non-Kaiser patients on age, maximum Abbreviated Injury Scale score (MAIS) by body region, Injury Severity Score (ISS), head injury severity, and blunt or penetrating injury and disposition. Kaiser patients were significantly younger, more likely to have blunt injury, and had a lower death rate. Significant predictors of repatriation were an MAIS score > or = 3, abdominal or extremity injury, and an ISS score of 26 to 40. The mean LOS for all Kaiser patients was 7.6 days, compared with 4.8 for controls (p = 0.20). However, mean LOS was significantly longer in repatriated Kaiser patients compared with controls (16 vs. 7.8 days, p < 0.0005). Kaiser reimbursement rates were comparable with commercial payors, but higher than others. A relatively small number of severely injured patients account for a large percentage of costly trauma care. Analyses of patient subsets are necessary for trauma centers to negotiate suitable relationships with managed care plans. A prospective study is needed to examine the cost efficiency of early transfer of managed care patients.

Abstract
OBJECTIVE To provide uncompensated elective low-risk outpatient surgery for uninsured patients through a coalition of volunteer physicians, nurses, and hospitals. DESIGN Description of the process of establishing the Ambulatory Surgery Access Coalition (ASAC), the political and administrative obstacles encountered, and the clinical results of treatment of the first 25 patients in the pilot project. SETTING The ASAC includes the Kaiser Foundation Hospital, San Francisco, Calif, the University of California, San Francisco, the San Francisco General Hospital (SFGH), the San Francisco Department of Public Health, the San Francisco Consortium of Community Clinics, the Northern California Chapter of the American College of Surgeons, and the San Francisco Medical Society. A pilot program of uncompensated outpatient surgery was performed at the Kaiser Foundation Hospital. PATIENTS Twenty-nine patients were referred to the ASAC between January 1 and November 1, 1994. Twenty-six patients were judged to be candidates for surgery, and 25 patients met the criteria for the ASAC program. One patient was referred to SFGH for treatment because of a perceived increased risk for hospitalization after surgery. RESULTS Twenty-one patients underwent herniorrhaphy; three, excision of large inclusion cysts; and one, anal fistulotomy. Seventeen procedures were done under local anesthesia, seven under general anesthesia, and one under spinal anesthesia. None of the patients required hospital admission. No wound infections occurred. CONCLUSION The ASAC successfully provided uncompensated low-risk outpatient surgery to 25 low-income uninsured patients in San Francisco. The coalition hopes, first, to include other San Francisco hospitals and surgical specialties, and second, to serve as a model for other communities throughout the country.

Abstract
Several recent reviews have suggested that aggressive surgical intervention can reduce morbidity and mortality associated with intra-abdominal crises in AIDS patients. We reviewed our experience with 57 AIDS patients with 63 emergent laparotomies performed at 4 hospitals affiliated with the University of California in San Francisco. Fifty-five patients (96%) were homosexual men. Thirty-nine (68%) had been treated for an opportunistic infection. Indications for exploration included right lower quadrant pain consistent with appendicitis in 24 patients (38%), visceral perforation or obstruction in 11 (17%), right upper quadrant pain in 9 (14%), diffuse peritonitis in 8 (13%), and uncontrollable hemorrhage in 8 (13%). Perioperative mortality was 12% (7/57). Fifteen patients (26%) suffered major complications including pneumonia, sepsis, multi-organ failure, and intra-abdominal abscess. Forty-five of 50 survivors (90%) were receiving some type of chronic antimicrobial or antineoplastic chemotherapy, compared to only 2 of the 7 patients who died (28.6%) (P < 0.001). Lack of ongoing prophylactic treatment for AIDS-related disease, active opportunistic infections, Walter Reed VI classification, and ongoing sepsis at the time of exploration were noted to be associated with increased morbidity and mortality.

Abstract
BACKGROUND We studied differences in the incidence of appendiceal perforation in patients with acute appendicitis according to their insurance coverage. METHODS In a retrospective analysis of hospital-discharge data, we examined the likelihood of ruptured appendix among adults 18 to 64 years old who were hospitalized for acute appendicitis in California from 1984 to 1989. RESULTS After controlling for age, sex, psychiatric diagnoses, substance abuse, diabetes, poverty, race or ethnic group, and hospital characteristics, we found that ruptured appendix was more likely among both Medicaid-covered and uninsured patients with appendicitis than among patients with private capitated coverage (odds ratios, 1.49 [95 percent confidence interval, 1.41 to 1.59] and 1.46 [95 percent confidence interval, 1.39 to 1.54], respectively). After adjustment for the above factors, the risk of appendiceal rupture associated with a lack of private insurance was elevated at both county and other hospitals, but admission to a county hospital was an independent risk factor. In all income groups, appendiceal rupture was more likely with fee-for-service than capitated private coverage (overall odds ratio, 1.20 [95 percent confidence interval, 1.15 to 1.25]). CONCLUSIONS Among patients with appendicitis an increased risk of ruptured appendix may be due to insurance-related delays in obtaining medical care. Both organizational and financial features of Medicaid and various types or levels of private third-party coverage may be involved. The significant association between ruptured appendix and insurance coverage after adjustment for socio-economic differences suggests barriers to receiving medically necessary acute care that should be considered in current deliberations on health policy.

Abstract
Geriatric patients often require prolonged postoperative intensive care after complex surgery. These patients frequently are intubated, sedated or confused, and unable to participate in therapeutic decisions. There is much controversy surrounding the use of critical care in the elderly as well as prognostic uncertainty. This article reviews the medical, ethical, and legal issues that define the clinical principles involved in the decision to limit life support in geriatric patients.

Abstract
In 1993, it is estimated that 2 million Americans are infected with the human Immunodeficiency Virus (HIV). The Acquired Immune Deficiency Syndrome (AIDS) represents the most severe manifestation of infection with the virus. In the patient with AIDS, helper T lymphocytes are depleted resulting in a defect in cell mediated immunity. The resulting state of profound immunosuppression leads to susceptibility to rare infections and tumors. Although opportunistic infections have been seen in patients on immunosuppressive therapy, those associated with AIDS are much more severe and extensive. Many patients present with symptoms that mimic acute surgical emergencies. In other cases, the presentation has been one of a more chronic disease state. Some of the diseases associated with AIDS are directly attributable to the effects of the HIV virus. In all of these categories, there are some patients who will benefit from surgical therapy. In many cases medical therapy will be more appropriate. The evaluation of these patients can represent a major diagnostic challenge to the surgeon. A familiarity with these disease processes is essential for timely diagnosis and appropriate treatment.

Abstract
OBJECTIVES To determine if splenectomy results in an increased risk for perioperative infection when analyzed against splenic repair and to identify factors associated with perioperative infection, respiratory complication, and admission to the intensive care unit following surgery for splenic trauma. DESIGN Data were collected retrospectively from hospital records and analyzed using stepwise multiple logistic regression. SETTING San Francisco (Calif) General Hospital, an urban level 1 trauma center. PATIENTS All patients (n = 252) undergoing operation for traumatic splenic injury at San Francisco General Hospital from 1984 through 1990. Patients who died within 24 hours of presentation were excluded from the study. MAIN OUTCOME MEASURES Perioperative infection, respiratory complications, and admission to the intensive care unit. RESULTS Infection rates and the types of organisms yielded in cultures were similar between patients who underwent splenectomy and repair. Gram-negative and gram-positive organisms were found in equal numbers, and in no group did encapsulated organisms predominate. Splenectomy had no independent impact on any of the three outcome measures. Total blood transfusion was found to be the only independently significant variable associated with perioperative infection and respiratory complication. Total blood transfusion of more than 2 U and Injury Severity Score of greater than 25 were independently significantly associated with admission to the intensive care unit. CONCLUSIONS The choice between splenectomy and splenic repair does not affect the risk for perioperative infection following injury, whereas blood transfusion significantly increases the risk for perioperative infection, respiratory complication, and admission to the intensive care unit.

Abstract
The resuscitation of patients with cardiopulmonary arrest from a penetrating injury of the heart requires emergency thoracotomy and control of hemorrhage. Suture control may be technically difficult in patients with large or multiple lacerations. Emergency cardiac suturing techniques expose the surgeon to the risk of a contaminated needle stick. After we determined that rapid control of hemorrhage from cardiac lacerations could be achieved in anesthetized sheep with the use of a standard skin stapler, the technique was applied in the clinical setting. Twenty-eight patients underwent emergency stapling of 33 cardiac lacerations at our institution from September 1987 to December 1991. Seventy-nine percent (22) of the patients sustained stab wounds, and 21% (6) were injured by gunshots. Fifty-eight percent (19) of the injuries involved the right ventricle, 27% (9) involved the left ventricle, 9% (3) involved the right atrium, and 6% (2) involved the left atrium. In 93% (26) of the patients, control of hemorrhage was achieved within 2 minutes of exposure of the injuries. Both patients in whom control could not be achieved had sustained large-caliber gunshot injuries. Fifteen (54%) of the patients survived, including one patient with two cardiac lacerations and another with three lacerations. Of the surviving patients, two had mild neurologic deficits. No personal contamination occurred related to the use of the stapler. We conclude (1) cardiac stapling is highly effective in the management of hemorrhage from penetrating injury, particularly in the setting of multiple cardiac lacerations; (2) the technique may not be effective with certain types of gunshot wounds; and (3) the use of the stapler for emergency cardiorrhaphy eliminates the risk of personal contamination from a needle stick.

Abstract
Reports in the surgical literature are few regarding common intra-abdominal disease processes, such as gallstone disease or appendicitis, in patients with AIDS and instead have focused on AIDS-related intra-abdominal diseases that infrequently require surgical intervention unless complicated by bleeding, obstruction, or perforation. A literature review for appendicitis in AIDS patients revealed only 30 well-documented cases drawn from 13 studies, with a 40% perforation rate and frequent delays and errors in diagnosis. A 7-year experience with 28 patients with appendicitis and AIDS from 4 urban San Francisco hospitals is reviewed. There were no perioperative deaths and an 18% postoperative complication rate. Five patients (18%) were found to have normal appendices with other intra-abdominal pathology, and an AIDS-related etiology for appendicitis was discovered in 7 of 23 patients with appendicitis (30%). With the exception of diffuse versus localized abdominal pain, no preoperative symptom or sign was useful in differentiating AIDS-related and non-AIDS-related disease. Aggressive use of ultrasound and abdominal computed tomographic scanning, along with early surgical intervention, is recommended.

Abstract
An increasing number of HIV-infected patients will require surgical therapy. The methods of diagnosis and therapeutic planning for HIV-infected patients are the same as for all other patients. Surgery should be advised if an operation is likely to have a positive effect on the patient's life. Most patients with AIDS with diseases for which surgical therapy is advantageous benefit from carefully chosen operations designed to solve specific problems.

Abstract
Medical records of 52 human immunodeficiency virus (HIV)-infected patients who underwent a total of 80 anorectal operations from January 1985 to January 1990 were retrospectively reviewed to determined whether anorectal surgical wounds healed in HIV-infected patients and the mean survival time of these patients after surgery. Twenty-four operations were performed in asymptomatic HIV-infected patients, 19 in HIV-infected patients with persistent lymphadenopathy, and 37 in patients with acquired immunodeficiency syndrome. Wounds healed in 49 patients (94%). The mortality rate 30 days after surgery was 2%. There were no major complications. The mean survival time of HIV-infected patients after surgery was 15 months. We conclude that anorectal surgical wounds heal in most HIV-infected patients and that the survival time after surgery of HIV-infected patients with anorectal disease justifies appropriate surgical treatment.

Abstract
We retrospectively reviewed six patients with squamous cell carcinoma of the anus (SCCA) and human immunodeficiency virus (HIV) infection treated between 1985 and 1988. All six patients were homosexual men. Five patients had AIDS and one was HIV-positive. The most common symptoms and signs were pain (n = 5), mass (n = 5), and bleeding (n = 5). The average tumor size was 3.2 cm with a range of 1-10 cm. Five tumors were located in the anal canal and one at the anodermal junction. One patient was treated with biopsy alone, one with local excision, one with wide local excision and radiation therapy, and two with diverting colostomy. The average follow-up was 8 months. Of the five AIDS patients, two died, one was transferred to a hospice facility, one was lost to follow-up, and one remains alive 1 year following treatment. The HIV-positive patient died secondary to metastatic SCCA. This group of patients raises the question of a possible association between HIV and SCCA.

Abstract
We retrospectively reviewed eight patients with biopsy-proven anorectal Kaposi's sarcoma (KS) treated between 1984 and 1989 at San Francisco General Hospital. All patients were homosexual men with the acquired immunodeficiency syndrome (AIDS). The average age was 34 years. Three patients had primary rectal KS without metastases. Five patients had disseminated KS with lesions throughout the alimentary tract, viscera, skin, or local lymph nodes. Three patients were treated with radiation or chemotherapy. Five patients had disseminated KS with lesions throughout the alimentary tract, viscera, skin, or local lymph nodes. Three patients were treated with radiation or chemotherapy. Five patients with advanced AIDS received no specific treatment for anorectal KS. Follow-up ranged from 1 month to 5 years. Three of the untreated patients and the three patients treated with chemotherapy or radiotherapy were alive 1 month to 5 years after diagnosis. Aggressive surgical treatment of anorectal KS is not indicated.

Abstract
We undertook an observational study of 1307 consecutive surgical procedures at San Francisco General Hospital to record descriptions of intraoperative exposures to blood and other body fluids, determine the factors predictive of these exposures, and identify interventions that might reduce their frequency. During a two-month period, circulating nurses took note of parenteral and cutaneous exposures to blood and recorded information about all procedures. In a follow-up validation study, 50 additional procedures were observed by the study investigators to determine the accuracy of the data collected by the nurses. A total of 960 gloves used by surgical personnel during the validation study were examined to determine the perforation rate. Accidental exposure to blood (parenteral or cutaneous) occurred during 84 procedures (6.4 percent; 95 percent confidence interval, 5.1 to 7.8 percent). Parenteral exposure occurred in 1.7 percent. The risk of exposure was highest when the procedures lasted more than three hours, when blood loss exceeded 300 ml, and when major vascular and intraabdominal gynecologic surgery was involved. Neither knowledge of diagnosed human immunodeficiency virus (HIV) infection nor awareness of a patient's high-risk status for such infection influenced the rate of exposure. Double gloving prevented perforations of the inner glove and cutaneous exposures of the hand. We conclude that all surgical personnel are at risk for intraoperative exposure to blood. Our data support the practice of double gloving and the increased use of water-proof garments and face shields to prevent mucocutaneous exposures to blood. No evidence was found to suggest that preoperative testing for HIV infection would reduce the frequency of accidental exposures to blood.

Abstract
Four homosexual male patients with giant anal carcinomas, ranging from 10 to 17 cm in diameter, are presented. These patients were not candidates for abdominoperineal resection because of fixation to adjacent structures. Common symptoms included pain, sepsis, anemia, incontinence, and weight loss. Diverting colostomy was performed in all patients. Two of the four patients were treated by wide local excision of the tumors for palliation. Two patients were treated with chemotherapy and radiation therapy. Three of the four patients died within 12 months. The authors conclude that diverting colostomy and wide local excision of giant anal cancers offer effective palliation of local wound problems in selected cases.

Abstract
We investigated decisions to withhold or withdraw life support from patients in the medical-surgical intensive care units at the Moffitt-Long Hospital of the University of California and San Francisco General Hospital, from July 1987 through June 1988. Among 1719 patients admitted to the two intensive care units, life support was withheld from 22 (1 percent) and withdrawn from 93 (5 percent). The reason for limiting care was poor prognosis. Of these 115 patients (18 of whom were considered brain-dead), 89 died in the intensive care unit (accounting for 45 percent of all deaths there), and all but 1 of the remaining patients died after transfer from the intensive care unit. Thirteen (11 percent) had earlier expressed the wish that their terminal care be limited, but this affected care in only four cases. Only 5 of the 115 patients made the actual decision to limit care; the others were incompetent at the time. Of the latter, 102 had families who participated in the decision; family members of the other 8 incompetent patients could not be found, and the decisions were made by physicians. Only 10 families initially disagreed with the recommendations to limit care, and they later agreed. The median duration of intensive care among the patients from whom life support was withheld or withdrawn was eight days at Moffitt-Long Hospital and four days at San Francisco General, as compared with medians of three and one days, respectively, for other patients who died in the intensive care units. We conclude that although life-sustaining care is withheld or withdrawn relatively infrequently from patients in the intensive care unit, such decisions precipitate about half of all deaths in the intensive care units of the hospitals we studied. In most of these cases the patients are incompetent, but physicians and families usually agree to limit care.

Abstract
We reviewed our experience with tracheal and bronchial trauma from 1977 to 1988. There were 22 patients with tracheobronchial injuries treated in this period. Seventeen (77%) of the injuries were due to penetrating trauma and five (23%) were due to blunt trauma. Thirteen patients had major associated injuries, including six esophageal injuries. The most common physical findings were tachypnea (13 patients) and subcutaneous emphysema (nine patients). Eight patients presented with airway obstruction. All patients with penetrating cervical tracheal injuries underwent neck exploration and primary repair. All blunt injuries were diagnosed by bronchoscopy. Three patients with blunt injuries were treated with primary repair. Two patients with blunt chest trauma and small bronchial tears were treated nonoperatively with good results. All three deaths (14% mortality rate) were due to associated injuries. We conclude that patients with penetrating tracheobronchial injuries should be managed by surgical exploration and primary repair, although selected patients with blunt injury may be treated nonoperatively.

Abstract
Blunt abdominal trauma results in potentially life-threatening injuries that require organized rapid evaluation and treatment. Resuscitation of hemodynamically unstable patients should be completed in the operating room if retroperitoneal hemorrhage is not strongly suspected. DPL and abdominal CT scans are methods of studying the injured abdomen, and each has advantages and disadvantages. The clinician must choose the appropriate study based on the clinical question raised by each patient. Repeated frequent physical examinations and serial laboratory tests are essential to exclude a missed injury. Deterioration of hemodynamic status or abdominal examination are indications for urgent laparotomy regardless of the initial diagnostic impressions.

Abstract
Eighteen patients with swollen fingers suggesting acute suppurative tenosynovitis were studied by ultrasonography. All patients received intravenous antibiotics. Twelve patients required surgical drainage. Eleven of 12 patients had sonographic evidence of both a swollen tendon and fluid in the flexor sheath. Eleven of the 12 patients operated on had purulent fluid in the flexor sheath. Four of the operative cases were culture positive and four were culture negative. All six patients treated only with antibiotics had swollen tendons, but five of the six had no sonographic evidence of fluid in the flexor sheath. All patients had a full recovery. Sonographic evidence of fluid in the flexor sheath is a useful sign in the early diagnosis of acute suppurative flexor tenosynovitis.

Abstract
UNLABELLED The mechanism of central nervous system (CNS) protection during proximal descending thoracic aortic cross-clamping (PDTAC) for aortic surgery using calcium channel blocking agents is not known. In order to determine the effect of verapamil on CNS blood flow during PDTAC, we calculated cerebral cortical (CC), proximal spinal cord (PSC), and distal spinal cord (DSC) blood flow using the microsphere method in Grade I beagles. Flow calculations were obtained at baseline (pre-PDTAC), following mobilization of the proximal descending aorta for 5-8 cm by ligating 3-5 pairs of intercostal arteries (ICA), during PDTAC (45 min), and during maximal reperfusion. Two groups were studied: 1) control (Cont) untreated (n = 5); 2) verapamil (Ver) treated (0.4 mg/kg IV just before PDTAC and just before reperfusion) (n = 5). CONCLUSIONS I) Proximal ICA ligation produces no compromise to SC blood flow. II) Verapamil may protect the CNS by: 1) maintaining cerebral autoregulation during reperfusion; and 2) dampening hyperperfusion of the distal SC during reperfusion.

Abstract
We reviewed 144 consecutive patients with flail chest and/or pulmonary contusion between 1979 and 1984. The purpose was to analyze the factors adversely affecting morbidity and mortality. There were 97 males and 47 females, with an average age of 40 years +/- 18 S.D. (range, 2-83). Seventy-five per cent of the injuries were caused by motor vehicle accidents, with the remainder due to falls (17%), cardiopulmonary resuscitation (4%), altercations (2%), or falling objects (2%). The Injury Severity Score (ISS) averaged 32 +/- 14 S.D. in all survivors versus 60 +/- 14 S.D. in those who died. Eighty-three patients (58%) required mechanical ventilation. Thirty-six patients died (25%). Isolated pulmonary contusion or flail chest had a mortality of 16% each. However, the mortality more than doubled when there was a combined pulmonary contusion and flail chest (42%). More than half of all deaths were directly attributed to central nervous system injuries with another third due to massive hemorrhage. Factors that were associated with a higher morbidity and mortality included severe associated thoracic injuries, a high ISS, the presence of shock, falls from heights, and the combination of pulmonary contusion and flail chest.

Abstract
We report the prevalence of sensory loss and hand deformity in 63 patients with Hansen's disease in American Samoa. Open ulceration, the most common deformity, was present in 41% of patients; sensory abnormalities were present in 54% and were bilateral in 65%. The presence of abnormal sensibility correlated with a high percentage of other deformities. Hand abnormalities were most prevalent in lepromatous patients and were related to a prolonged duration of disease. Nerve thickening did not appear to be a helpful clinical finding to assess the degree of sensory loss.

Abstract
A technique for construction of a functional loop colostomy is described for the management of colonic injuries in which complete fecal diversion is not required. The colostomy and mucous fistula are converted into a functional loop colostomy at the initial procedure and exteriorized through a single stoma. Subsequent colostomy closure is simplified. Intraperitoneal colostomy closure can usually be performed by mobilizing the colon at the stoma site without resorting to formal laparotomy.

Abstract
We analyzed the records of 50 head-injury patients managed by general surgeons from 1974 to 1981 in American Samoa. Patients were divided into three groups. Group 1 was awake and alert (n = 24). Group 2 was obtunded by talking (n = 7). Group 3 was comatose (n = 20). All patients were managed with diagnostic burr-hole procedures. Eighteen of the 20 unconscious patients had an intracranial hematoma. Five of the seven obtunded patients had an intracranial hematoma. Three of the nine deaths were directly attributable to a delay in diagnosis of an intracranial hematoma. We conclude that a burr-hole procedure in unconscious head-injury patients in rural hospitals is a safe and effective method of diagnosing and treating extradural and subdural hematomas. General surgery residents should receive training in operative head-injury management, to improve the care of the head-injury victim in rural America.

Ten cases of pyomyositis of the iliacus muscle are described in otherwise healthy young Samoans. The correct diagnosis was frequently delayed. Staphylococcus aureus was the most common pathogen isolated from drained abscesses. Preference for hip flexion was seen in six patients, and localized pain or induration at the anterior superior iliac spine were found in seven patients. These clues may help expedite a correct diagnosis.

Abstract
Two cases of pseudomalignant peripartum myositis ossificans of the finger are reported. The benign diagnosis is confirmed by the histologically characteristic zone phenomenon, consisting of a transition from an inner zone of proliferating spindle cells to a middle zone of well-oriented osteoid and finally to an outer zone of mature bone. In Case No. 1, because of the question of malignancy, a ray amputation was performed. In Case No. 2, the patient was observed during the peripartum period to show diminution in the size of the tumor. The lesion was eventually treated by local excision.

Abstract
Three patients under observation in ICUs developed mechanical upper airway obstruction requiring surgical intervention for airway control. One patient was treated by tracheotomy placed through a vertical midline incision and 2 patients were treated by cricothyroidotomy followed by elective tracheostomy and closure of the cricothyroidotomy. The literature of acute upper airway obstruction is reviewed and recommendations made for rapid assessment and management of these patients. The importance of rapid cricothyroidotomy through a small incision in patients unresponsive to less invasive measures is emphasized. The use of a small pediatric endotracheal tube placed through the cricothyroidotomy incision is suggested as a method to increase the speed and safety of the procedure and avoid the potential long-term complication of laryngeal stricture.
