Changing patterns in the management of splenic trauma: the impact of nonoperative management
Pachter HL; Guth AA; Hofstetter SR; Spencer FC
1998 May;227(5):708-717, Annals of surgery
OBJECTIVE: The recognition that splenectomy renders patients susceptible to lifelong risks of septic complications has led to routine attempts at splenic conservation after trauma. In 1990, the authors reported that over an 11-year study period involving 193 patients, splenorrhaphy was the most common splenic salvage method (66% overall) noted, with nonoperative management employed in only 13% of blunt splenic injuries. This report describes changing patterns of therapy in 190 consecutive patients with splenic injuries seen during a subsequent 6-year period (1990 to 1996). An algorithmic approach for patient management and pitfalls to be avoided to ensure safe nonoperative management are detailed. METHODS: Nonoperative management criteria included hemodynamic stability and computed tomographic examination without shattered spleen or other injuries requiring celiotomy. RESULTS: Of 190 consecutive patients, 102 (54%) were managed nonoperatively: 96 (65%) of 147 patients with blunt splenic injuries, which included 15 patients with intrinsic splenic pathology, and 6 hemodynamically stable patients with isolated stab wounds (24% of all splenic stab wounds). Fifty-six patients underwent splenectomy (29%) and 32 splenorrhaphy (17%). The mean transfusion requirement was 6 units for splenectomy survivors and 0.8 units for nonoperative therapy (85% received no transfusions). Fifteen of the 16 major infectious complications that occurred followed splenectomy. Two patients failed nonoperative therapy (2%) and underwent splenectomy, and one patient required splenectomy after partial splenic resection. There no missed enteric injuries in patients managed nonoperatively. The overall mortality rate was 5.2%, with no deaths following nonoperative management. CONCLUSIONS: Nonoperative management of blunt splenic injuries has replaced splenorrhaphy as the most common method of splenic conservation. The criteria have been extended to include patients previously excluded from this form of therapy. As a result, 65% of all blunt splenic injuries and select stab wounds can be managed with minimal transfusions, morbidity, or mortality, with a success rate of 98%. Splenectomy, when necessary, continues to be associated with excessive transfusion and an inordinately high postoperative sepsis rate

Human immunodeficiency virus and the trauma patient: factors influencing postoperative infectious complications
Guth AA; Hofstetter SR; Pachter HL
1996 Aug;41(2):251-255, Journal of trauma
OBJECTIVE: While immunosuppression 2 degrees to human immunodeficiency virus (HIV) infection should logically render HIV+ trauma victims more prone to infection after injury, little data is available regarding trauma outcome in this group of patients. Since the helper CD4+ lymphocyte count is a marker for progression of HIV-associated diseases, we examined the relationship between CD4+ counts, Injury Severity Score (ISS), and bacterial infectious complications in HIV+ trauma patients. METHOD: Retrospective review of 56 consecutive HIV+ trauma patients treated at a Level I trauma center. RESULTS: Nine patients (15%) developed significant infectious complications (four pneumonias, three soft-tissue infections, one urinary tract infection, one wound infection) with no pattern to the causative agents. Evaluation of CD4+ counts, white blood cell counts, serum albumin levels, blood transfusion requirements, and ISS revealed that only the ISS was associated with infectious complications. CONCLUSION: Despite the profound immunosuppression in this group of patients, the incidence of bacterial infectious complications was independent of the CD4+ count (p = 0.958), but was associated with increases in the ISS (p = 0.003)

The current status of nonoperative management of adult blunt hepatic injuries
Pachter HL; Hofstetter SR
1995 Apr;169(4):442-454, American journal of surgery
This review of 14 recent publications encompassing 495 patients highlights the current role of the nonoperative management of adult blunt hepatic injuries. When careful inclusion criteria were met, the most important of which is hemodynamic stability, a 94% success rate was achieved, clearly attesting to the safety and efficacy of this approach. A 0% liver-related mortality in these 495 patients was achieved, and there were no documented missed enteric injuries. Delayed hemorrhage that led to laparotomy occurred in 2.8% of patients. The mean length of hospital stay was 13 days, and the mean transfusion requirement was 1.9 units of blood per patient. Computed axial tomography scanning was essential and played an integral role in delineating the extent of the injury, identifying other intra-abdominal injuries that would mandate immediate laparotomy, and following the progress of injury resolution. Overall, 34% of blunt liver injuries were managed nonoperatively. As of 1993, however, available data confirms that 51% of adult reported blunt hepatic injuries have been treated nonoperatively. Rigid adherence to the described guidelines may allow the majority of blunt hepatic injuries to be treated nonoperatively. It should be stressed, however, that this method of patient management should only be undertaken at institutions where the appropriate resources necessary to deal with this patient population are readily available

Epithelioid hemangioendothelioma of the heart with distant metastases. A case report and literature review
Marchiano D; Fisher F; Hofstetter S
1993 Dec;34(6):529-533, Journal of cardiovascular surgery
Epithelioid hemangioendothelioma is an uncommon intermediate-grade vascular tumor which most often presents in soft-tissue and is known to occasionally metastasize. A primary cardiac occurrence of this tumor was resected from the left atrium of a 71 year-old woman. Four months later, she underwent gluteal exploration and resection of three nodules from her right buttock. These nodules, which resembled the previously resected tumor but showed features of malignant transformation, were identified as metastatic epithelioid hemangioendotheliomas. To the best of our knowledge, only one case of primary cardiac epithelioid hemangioendothelioma has been previously reported in the literature. We believe ours is the second such case and the first to demonstrate distant metastases. This rare case of primary cardiac epithelioid hemangioendothelioma with distant metastases is illustrative of many of the known features and behaviors of the tumor. The case is reviewed and discussed alongside a review of recent topical literature

Traumatic cysts of the spleen--the role of cystectomy and splenic preservation: experience with seven consecutive patients [see comments]
Pachter HL; Hofstetter SR; Elkowitz A; Harris L; Liang HG
1993 Sep;35(3):430-436, Journal of trauma
Nonparasitic secondary cysts (pseudocysts) of the spleen are uncommon and usually result from blunt abdominal trauma. A 3-year experience with 7 consecutive cases of posttraumatic splenic pseudocysts suggests an increased prevalence of this clinical entity. This report describes 7 adult patients (5 men and 2 women) with a mean age of 32 years, all of whom sustained relatively minor trauma within 5 years of admission. Persistent epigastric or left upper quadrant pain led to a CT scan diagnosis of splenic cysts that varied in size from 7 cm to 15 cm. Each patient underwent resection of the cyst-bearing portion of the spleen with preservation of the remaining normal splenic parenchyma. There were no deaths or complications in the entire group. Because posttraumatic splenic cysts are rare, the accumulation of a significant data base leading to firm conclusions is lacking.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgical diseases of the falciform ligament
Brock JS; Pachter HL; Schreiber J; Hofstetter SR
1992 Jun;87(6):757-758, American journal of gastroenterology
Surgical lesions of the falciform ligament are rare. Clinically, they present most often as a cystic abdominal mass, and less often as an abscess. Two cases of falciform ligament lesions are reported. The literature, histology, anatomy, clinical manifestations, and surgical management are detailed. Computerized axial tomography (CAT scan) is an essential tool in arriving at a correct preoperative diagnosis. Complete excision of the lesion is curative

Significant trends in the treatment of hepatic trauma. Experience with 411 injuries
Pachter HL; Spencer FC; Hofstetter SR; Liang HG; Coppa GF
1992 May;215(5):492-500, Annals of surgery
Several significant advances in the treatment of hepatic injuries have evolved over the past decade. These trends have been incorporated into the overall treatment strategy of hepatic injuries and are reflected in experiences with 411 consecutive patients. Two hundred fifty-eight patients (63%) with minor injuries (grades I to II) were treated by simple suture or hemostatic agents with a mortality rate of 6%. One hundred twenty-eight patients (31%) sustained complex hepatic injuries (grades III to V). One hundred seven patients (83.5%) with grades III or IV injury underwent portal triad occlusion and finger fracture of hepatic parenchyma alone. Seventy-three surviving patients (73%) required portal triad occlusion, with ischemia times varying from 10 to 75 minutes (mean, 30 minutes). The mortality rate in this group was 6.5% (seven patients) and was accompanied by a morbidity rate of 15%. Fourteen patients (11%) with grade V injury (retrohepatic cava or hepatic veins) were managed by prolonged protal triad occlusion (mean cross-clamp time, 46 minutes) and extensive finger fracture to the site of injury. In four of these patients an atrial caval shunt was additionally used. Two of these patients survived, whereas six of the 10 patients managed without a shunt survived, for an overall mortality rate of 43%. Over the past 4 years, six patients (4.7%) with ongoing coagulopathies were managed by packing and planned re-exploration, with four patients (67%) surviving and one (25%) developing an intra-abdominal abscess. One additional patient (0.8%) was managed by resectional debridement alone and survived. During the past 5 years, 25 hemodynamically stable and alert adult patients (6%) sustaining blunt trauma were evaluated by computed tomography scan and found to have grade I to III injuries. All were managed nonoperatively with uniform success. The combination of portal triad occlusion (up to 75 minutes), finger fracture technique, and the use of a viable omental pack is a safe, reliable, and effective method of managing complex hepatic injuries (grade III to IV). Juxtahepatic venous injuries continue to carry a prohibitive mortality rate, but nonshunting approaches seem to result in the lowest cumulative mortality rate. Packing and planned reexploration has a definitive life-saving role when used adjunctively in the presence of a coagulopathy. Nonoperative management of select hemodynamically stable adult patients, identified by serial computed tomography scans after sustaining blunt trauma is highly successful (95-97%)

The morbidity and financial impact of colostomy closure in trauma patients
Pachter HL; Hoballah JJ; Corcoran TA; Hofstetter SR
1990 Dec;30(12):1510-1513, Journal of trauma
During a 10-year period, 87 patients who had undergone elective colostomy closure at Bellevue Hospital were retrospectively reviewed in order to evaluate the morbidity of colostomy closure after traumatic injury and its financial impact. Sixty-two per cent of the colostomies were in the left colon and 38% were right sided. The interval from the original injury to colostomy takedown varied from 20 to 465 days, with a mean of 144 days. The mean postoperative hospital stay for the entire group was 15.13 days at a cost of $13,995. There were no deaths and no anastomotic leaks in the entire series, but a morbidity rate of 25% ensued. Small bowel obstruction was the most frequent significant complication, occurring in ten patients (11.5%) and resulting in a prolongation of hospital stay by 7 days at an additional cost of $6,500 per patient. One additional patient developed a subphrenic abscess which required operative drainage, necessitating an additional 24 days in the hospital at an increased cost of $22,200. Other complications which did not prolong hospital stay included eight superficial wound infections, one transient respiratory failure, and two patients who returned at a later date with incisional hernias at the stoma site. The 25% morbidity encountered in this series suggests that colostomy closure is not a low-morbidity procedure and should be considered as an important factor favoring primary repair. Coupled with the significant financial impact of both colostomy formation and takedown, ample justification exists for greater efforts in avoiding colostomy formation whenever feasible

Experience with selective operative and nonoperative treatment of splenic injuries in 193 patients
Pachter HL; Spencer FC; Hofstetter SR; Liang HG; Hoballah J; Coppa GF
1990 May;211(5):583-589, Annals of surgery
During the past decade splenic salvage procedures rather than splenectomy have been considered the preferred treatment for traumatic splenic injuries. Splenic preservation has been most often accomplished by splenorrhaphy and more recently by a controversial nonoperative approach. This report delineates indications, contraindications, and results with splenectomy, splenorrhaphy, and nonoperative treatment based on an 11-year experience (1978 to 1989) in which 193 consecutive adult patients with splenic injuries were treated. One hundred sixty-seven patients (86.5%) underwent urgent operation. Of these, 111 (66%) were treated by splenorrhaphy or partial splenectomy and 56 (34%) were treated by splenectomy. During the last 4 years, 26 additional patients (13.5%) were managed without operation. Patients considered for nonoperative treatment were alert, hemodynamically stable with computed tomographic evidence of isolated grades I to III splenic injuries. Overall 24% of the injuries resulted from penetrating trauma, whereas 76% of the patients sustained blunt injuries. Complications were rare, with two patients in the splenorrhaphy group experiencing re-bleeding (1.8%) and one patient (4%) failing nonoperative treatment. The mortality rate for the entire group was 4%. This report documents that splenorrhaphy can safely be performed in 65% to 75% of splenic injuries. Splenectomy is indicated for more extensive injuries or when patients are hemodynamically unstable in the presence of life-threatening injuries. Nonoperative therapy can be accomplished safely in a small select group (15% to 20%), with a success rate of nearly 90% if strict criteria for selection are met

Visceral Kaposi's sarcoma is a common manifestation of the acquired immune deficiency syndrome (AIDS). Most lesions are clinically silent, detected only by radiographic or endoscopic studies. We report the first instance of AIDS-related jejunal Kaposi's sarcoma presenting with small intestinal obstruction due to intussusception. Gastrointestinal Kaposi's sarcoma is a clinical problem that may occur more frequently in the future

The management of juxtahepatic venous injuries without an atriocaval shunt: preliminary clinical observations
Pachter HL; Spencer FC; Hofstetter SR; Liang HC; Coppa GF
1986 May;99(5):569-575, Surgery
Juxtahepatic venous injuries are usually fatal. The optimal method of dealing with these injuries remains controversial, but most experience has been with the insertion of an atriocaval shunt. However, the mortality rate with atriocaval shunting remains prohibitively high (60% to 100%). The experience at the Bellevue Hospital Trauma and Shock Unit during a 9-year period revealed a 50% mortality rate in four consecutive patients who underwent atriocaval shunting. As such, a different approach was used in the following five patients, all of whom survived. One additional patient died in the operating room before any definitive repair could be undertaken. Four steps are considered essential to the successful management of these patients: (1) compression of the injury site until adequate resuscitation has been achieved; (2) early recognition that a juxtahepatic venous injury exists, as indicated by failure of the Pringle maneuver to adequately arrest hemorrhage; (3) prolonged portal triad occlusion with hepatocyte protection by means of large doses of steroids and topical hypothermia (portal triad occlusion time in the nonshunted group ranged from 20 to 64 minutes with a mean occlusion time of 46 minutes; although a transient rise in liver function test results seemed to correlate with the length of ischemia time, neither hepatic dysfunction nor hepatic necrosis occurred; and (4) extensive finger fracture of the liver to the site of vascular injury for primary repair or ligation; the extent of the finger fracture varied from 15 to 30 cm in length and from 5 to 15 cm in depth. The successful results achieved in five consecutive patients who sustained juxtahepatic venous injuries treated without a shunt serve as a basis for recommending this operative approach

Management of penetrating wounds of the back and flank
Coppa GF; Davalle M; Pachter HL; Hofstetter SR
1984 Dec;159(6):514-518, Surgery, gynecology & obstetrics
The results of a retrospective and prospective study of patients with penetrating wounds of the back and flank showed that physical examination alone was accurate in 72 and 83 per cent, respectively. The inaccuracy was primarily due to false-negative examinations. The most commonly injured organs were the liver and kidney. The presence of gross hematuria and intravenous pyelography proved to have an accuracy rate of 95 per cent in patients studied prospectively. Peritoneal lavage, although similarly accurate (95 per cent), was associated with a 10 per cent false-negative result when the wound was located in the back. Guidelines for the management of these patients include hospital admission, careful physical examination, urinalysis by dipstick and cell count, intravenous pyelography and peritoneal lavage. Initial hypotension usually is associated with visceral injury and is an indication for exploratory laparotomy. Strict adherence to these guidelines was associated with a negative exploration rate of less than 10 per cent and a decrease in the number of patients observed with visceral injury from 50 to 6 per cent

1984 Jul-Aug;8(4):237-239, Computerized radiology
Surgical removal of foreign objects (FO) lodged in the body may be difficult because of uncertain 3-dimensional localization on conventional roentgenograms. Furthermore, low-density FO may not be detectable on roentgenograms. CT was performed in 8 patients with FO lodged in the extremities, and was found helpful because, (1) it detected 4 low-density FO's missed on roentgenograms, and (2) it facilitated surgical removal by displaying the precise 3-dimensional location of these objects

A prospective comparison of two regimens of prophylactic antibiotics in abdominal trauma: cefoxitin versus triple drug
Hofstetter SR; Pachter HL; Bailey AA; Coppa GF
1984 Apr;24(4):307-310, Journal of trauma
To determine the best antibiotic regimen to employ in patients undergoing laparotomy for trauma, a randomized prospective study was designed comparing cefoxitin alone with a triple-drug regime of an aminoglycoside, ampicillin, and clindamycin. One hundred nineteen consecutive patients sustaining abdominal trauma (97 penetrating; 22 blunt) were divided by date of admission to a 24-hour course of antibiotics. The overall infection rate was 16.0%, with 14.5% of the cefoxitin-treated patients, and 18.0% of the triple-drug-treated patients developing an infectious complication. Excluding remote site infections, the abdominal wound and intraperitoneal infection rates were 13.0% for cefoxitin-treated patients, and 12.0% for triple-drug-treated patients. There was one instance of oliguric renal failure questionably related to an aminoglycoside. It is concluded that a 24-hour course of cefoxitin is a safe and effective prophylactic antibiotic regime in patients undergoing laparotomy for trauma

Experience with the finger fracture technique to achieve intra-hepatic hemostasis in 75 patients with severe injuries of the liver
Pachter HL; Spencer FC; Hofstetter SR; Coppa GF
1983 Jun;197(6):771-778, Annals of surgery
The most important concept emerging from the management of complex hepatic trauma is that direct suture ligation of severed blood vessels and bile ducts is the most effective treatment. Three essential maneuvers are necessary: (1) the use of the finger fracture technique to expose the laceration widely, so that individual ligation of severed blood vessels and bile ducts can be accomplished under direct vision; (2) occluding the portal triad for 20 to 60 minutes; (3) closure of the hepatic incision over a viable omental pedicle. Two hundred consecutive patients with hepatic injuries were treated at the Trauma and Shock Unit of Bellevue Hospital between July 1976 and January 1982. One hundred and twenty-five injuries (63%) could be managed by superficial suture and drainage alone; 75 (37%) more extensive injuries required additional therapy; 47 of the 75 injuries required inflow occlusion for periods of up to 60 minutes, with the mean occlusion time of 30 minutes. All patients were pretreated with 30 to 40 mg/kg of Solu-Medrol prior to cross-clamping the portal triad. In addition, the liver was cooled to 27-32 degrees C topically by pouring 1 liter of iced Ringer's lactate directly on the liver surface, monitoring the temperature with an intra-hepatic probe. Ischemia time exceeded 20 minutes in 70%, 30 minutes in 40% and 60 minutes in 7% of patients. This approach, with complex hepatic trauma, has been dramatically effective. There were only four deaths (5.3%). One (1.3%) patient required reoperation for bleeding; three patients (4%) developed perihepatic abscesses; and two patients (3%) developed biliary fistulae that spontaneously closed. An extended right hepatectomy was necessary in the one patient who required reoperation for bleeding. This represents the only case of a formal hepatic resection in this series. Hepatic artery ligation was not employed in any case. These experiences strongly endorse the direct approach to the treatment of major hepatic lacerations by opening a lacerated liver sufficiently to ligate lacerated blood vessels and bile ducts, followed by closure over an omental pedicle. The wide-spread adoption of this technique will probably lower the mortality from massive liver injuries to 5-10%

Air embolism: a lethal but preventable complication of subclavian vein catheterization
Coppa, G F; Gouge, T H; Hofstetter, S R
1981 Mar-Apr;5(2):166-168, Journal of parenteral & enteral nutrition. JPEN
Air embolism (AE) is a rare but lethal complication of subclavian vein catheterization (SVC). Although treatable, if recognized promptly, attention should be directed towards prevention. SVC has been used at New York University Medical Center since 1969 for parenteral nutrition; its safety and complications have been recognized and reported. Since 1976, 14 patients with AE from SVC have been observed. Thirteen occurred as a sudden catastrophic event associated with disconnection of the catheter; all had significant morbidity; 4 (29%) died; 9 (65%) had associated profound neurologic deficit from which 5 recovered completely. Five others had cardiorespiratory morbidity but also recovered. In 1 surviving patient air was aspirated from the right atrium with immediate improvement. Survivors had evidence of pulmonary AE characterized by hypoxia. AE is a syndrome of respiratory distress, hypotension, and neurologic deficit of sudden onset. Immediate treatment is aspiration through the catheter in the left lateral steep Trendelenburg position. Review of our experience with AE suggests that lack of integrity of the connection between the catheter and the intravenous tubing was the responsible mechanism in the majority of case (93%). Secure fixation of these connections is vital for the prevention of AE

Acute adhesive obstruction of the small intestine
Hofstetter, S R
1981 Feb;152(2):141-144, Surgery, gynecology & obstetrics
A review of the management of adhesive small bowel obstruction revealed many hazards of long intestinal intubation therapy. When compared with those patients treated by fluid and electrolyte repletion and laparotomy within 24 hours, patients treated by prolonged tube suction had a longer hospital course, 22.6 versus 15.3 days; longer postoperative ileus, 7.4 versus 6.5 days, and greater technical problems at operation. This latter group also had a greater incidence of extensive postoperative complications and erroneous diagnoses. Long tubes were successful in only 21 patients and were most ineffective in those with complete obstruction as observed on roentgenograms. Patients with a prior abdominal surgical procedure, absence of any signs of strangulation and partial small bowel obstruction on roentgenograms, may be treated initially by long tube decompression and careful monitoring. Lack of definite improvement in 24 hours demands laparotomy. The value of intraoperative intestinal decompression is questionable

To compare the accuracy and safety of open abdominal paracentesis and lavage vs percutaneous paracentesis and lavage, 210 consecutive patients were prospectively randomized into two groups of 105 each. There were no false-negative diagnoses in either group. The accuracy rate for the open method was 98.1%, and 91.4% for the percutaneous method. Six major complications were encountered with the percutaneous method, for a complication rate of 5.7% compared with no major complications with the open method. The results suggest that the open technique is superior to the percutaneous method
