This study reviews low velocity gunshot wounds of the left upper quadrant of the abdomen and presents four cases recently treated at Boston City Hospital. All patients sustained multiple intraabdominal organ injuries and underwent prompt exploration. Hypotension on admission seemed to be the most reliable sign for a prolonged and complicated hospital course. The essential preoperative studies in stable patients should include a chest x-ray and intravenous pyelogram. Intraoperatively, injury to the body or tail or the pancreas is best managed by distal pancreatectomy and sump drainage. Exploration of the retroperitoneum is warranted for bleeding from the kidney. Initial maneuvers should be designed to control hemorrhage from the renal pedicle. If this is unsuccessful or the renal parenchyma is badly fragmented, nephrectomy should be performed. The complications noted in our patients, infection (pneumonia and left subphrenic abscess) and hemorrhage, are comparable to those reported in most large series. Pancreatic complications (fistulas, pseudocysts, and pancreatitis) were not noted.

Bilateral nephrectomy was performed in 53 patients on regular haemodialysis. The indications were pyelonephritis in 30, polycystic kidneys in 6, glomerulnephritis in 7, uncontrollable hypertension in 9 and horseshoe kidney in 1. In 87 per cent of cases the operation was carried out as a separate procedure prior to transplantation. The mortality was 9 per cent and the postoperative complications included hypotension, clotting of arteriovenous shunts, pneumonia and subphrenic abscess. As a result of our experience we have revised our indications for bilateral nephrectomy which now are pyelonephritis only when associated with persistent bacteriuria or ureteric reflux, polycystic kidneys and uncontrollable hypertension.

Between 1980 and 1990 12 patients (5 male, 7 female) were operated on for acute infectious pericarditis at a mean age of 42 years. The infections were 6 bacterial (purulent 4, abscess 2), 4 tuberculous, 1 viral and 1 Candida. Pericarditis resulted from contiguous spread of infection from bilateral pneumonia in 3 patients, from subphrenic abscess in 2 and followed bacteremia in 1. Clinical signs were: tamponade/shock in 9, elevated jugular venous pressure in 11, edema in 6, hepatomegaly in 6, ascites in 1, and pericardial friction rub in 3. A preoperative pericardiocentesis in 9 patients allowed only 4 positive microbiological diagnoses and was an insufficient drainage in all cases. The preoperative mean NYHA class was 3.3. The pericardectomy was total in 9 patients and partial in 3. Total mortality was 1/12 patients (8%) with one late death due to recurrent tuberculous pericarditis. No patient with purulent pericarditis died. Another recurrence occurred 6 months after acute viral pericarditis. Atrial fibrillation in one patient was the only postoperative complication. After a mean follow-up period of 48.5 months no cardiac constriction had occurred in 11 surviving patients Actuarial survival after pericardectomy is 100% after 1 month and remains 91% after 5 years. The mean NYHA class has significantly improved to 1.2 (p less than 0.05) at the end of the follow-up. We conclude that pericardectomy combined with a specific antimicrobial therapy is a safe treatment for acute infectious and especially purulent pericarditis with low mortality and excellent longterm results. Early pericardectomy allows rapid decompression of the heart, removal of intrapericardial adhesions and infected tissue and prevents late constriction.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-six patients underwent resection of the thoracic esophagus without a thoracotomy for the management of cancer of the cervical esophagus (2 patients), middle third and lower third of the esophagus (4 patients and 23 patients, respectively), and the gastroesophageal junction (17 patients). In addition to a total esophagectomy, two patients required a laryngectomy and seven patients had a total gastrectomy. Intraoperative bleeding occurred in three patients. Postoperative complications included subphrenic abscess (Candida) (2 patients), diaphragmatic hernia (1 patient), and salivary fistula (11 patients). Three patients died in the postoperative period from necrosis of interposed colon, pneumonia, and liver failure due to liver metastasis. The average blood loss was 1,300 ml, the duration of surgical procedure was 5.3 hours, and the hospital stay was 21 days. The survival rates at 1, 2, and 3 years were 80 percent, 50 percent, and 33 percent, respectively. Transhiatal esophagectomy can be considered a sound alternative to transthoracic esophagectomy in the management of tumors involving the cervical and lower esophagus. Small lesions of the middle third should also be considered for this procedure, however, bulky lesions of the upper esophagus are better removed by thoracotomy.

Although the first Aeromonas strain was described by Zimmermann as early as in 1890, it took 60 years until Caselitz established human pathogenicity of strains then called "Vibrio jamaicensis". Since then, and especially in the last 10 years, there have been increasing numbers of reports on different infections caused by members of the genus Aeromonas. These include sepsis; meningitis; cellulitis; necrotizing fasciitis; ecthyma gangrenosum; pneumonia; peritonitis; conjunctivitis; corneal ulcer; endophthalmitis; osteomyelitis; suppurative arthritis; myositis; subphrenic abscess; liver abscess; cholecystitis and/or ascending cholangitis; urinary tract infection; endocarditis; ear, nose, and throat infections; balanitis; etc. The role of Aeromonas in gastrointestinal disease is very controversial. Increasing epidemiological data suggest that these organisms play a major role in enteric infections, but so far enteropathogenicity has not been demonstrable in experiments where volunteers were given high numbers of Aeromonas possessing different virulence factors. Virulence factors include hemolysin(s), enterotoxin(s), hemagglutinins, invasivity, and others; but these are not found more frequently in strains isolated from patients with diarrhea than from healthy controls. Whether there is a correlation between species and disease remains to be elucidated and requires more information about the taxonomy of this genus.

We reviewed retrospectively the septic postsplenectomy complications after splenic rupture from abdominal trauma in 53 patients treated in the last five years (1984-1988). We recorded a higher incidence of complications (pneumonia, subphrenic abscess) in these patients than in those who underwent clean surgery during the same period, but we did not demonstrate the same difference in other infectious processes (infection of the surgical wound). Infections had a higher incidence in patients with splenic rupture with associated lesions (54.10%) than in those with only a splenic lesion (37.50%) (SD p less than 0.05). The predominant agents usually isolated were aerobic Gram-positive. We remark the importance of open drainage systems (Penrose type) in the genesis of subphrenic abscesses.

Twenty nine patients of an intensive care unit (9 women and 20 men), aged 63.9 +/- 15.8 years, with a mean body weight of 62.5 +/- 11.8 kg were treated during 9.4 +/- 2.1 days by aztreonam (2 x 1 g/24 h) administered by short infusion (30 min) for a severe infection due to a Gram-negative bacilli. The primary (n = 25) or nosocomial (n = 4) infection sites were a peritonitis (14), a septicaemia (6), a cholecystitis (6), a pyelonephritis (5), a cholangitis (2), a subphrenic abscess (1) or a pneumonia (2). The isolated Gram-negative bacilli were all susceptible to aztreonam, their MIC being less than or equal to 0.5 micrograms/ml, except for a Pseudomonas aeruginosa (MIC = 4 micrograms/ml). Aztreonam was administered as a single therapy to 7 patients and in association with metronidazole (18) and/or penicillin G (14) to 22 patients; in fact, anaerobes were isolated in ten patients. The mean serum concentrations of aztreonam, as measured by HPLC, before and after the 7th administration respectively were 83.2 +/- 17.5 and 6.1 +/- 5.5 micrograms/ml for peak and through levels. The treatment of the 29 infections was a success in all the cases. No complication occurred due to the presence of Gram positive cocci (n = 4) in the first bacteriological sample, or due to the emergence (n = 12) of Gram positive cocci, except for one case of sepsis of the abdominal wall by Staphylococcus aureus. Aztreonam (2 x 1 g/24 h) may be a suitable alternative for the treatment of severe infections of intensive care units, mostly due to Gram-negative bacilli.

A hundred patients scheduled for cholecystectomy were randomized to either thoracic epidural anaesthesia and analgesia for 24 h with bupivacaine intraoperatively about 100 mg and 15 mg/h thereafter (TEA) for postoperative analgesia, TEA combined with general anaesthesia (low dose fentanyl) (TEA + GA) and general anaesthesia (GA) (low dose fentanyl). During TEA and TEA + GA the arterial pressure was significantly decreased as compared with GA. TEA was associated by an intense haemodilution in comparison with GA. Blood glucose and plasma cortisol responses were significantly suppressed by TEA. The decreases in peripheral blood lymphocyte and eosinophilic counts observed after operation under GA was significantly reduced by TEA. The increase in the neutrophil count was inhibited by TEA but the increase in non-filamented neutrophils was significantly augmented by TEA. The postoperative alleviation of the alteration of the above mentioned parameters by TEA was slightly diminished in the TEA + GA group. However, we found no significant reduction in cardiac dysrhythmias (TEA 7%, TEA + GA 7% and GA 10%), ST-segment depression (TEA 17%), TEA + GA 3.3% and GA 12.5%), wound complication (TEA 3%, TEA + GA 0%, GA 0%), pneumonia (TEA 3%, TEA + GA 3% and GA 0%), subphrenic abscess (TEA 6%, TEA + GA 0%, GA 3%), mortality (TEA 0%, TEA + GA 3%, GA 0%), and urinary tract infect (TEA 17%, TEA + GA 7% and GA 2.5%). Since an equal number of patients in each group, about 30%, suffered one or more of the postoperative complications this epidural analgesia was not effective in reducing postoperative morbidity albeit the significant alleviation of the postoperative stress response.

Endoscopic sphincterotomy is an available nonoperative alternative treatment for recurrent or residual common bile duct stones. Nevertheless, immediate, intraoperative and definitive treatment is needed in patients with common duct stones and other pathologies that are prone to develop into such complications, which is important especially in aged high-risk patients during recurrent operations and nonoperative instrumental interventions. To evaluate the safety of choledochoduodenostomy in elderly patients, we reviewed our experience with 55 patients over the age of 70 years with benign biliary tract diseases. Even though the majority of patients (69%) had obstructive jaundice and were operated on urgently, there was one death (1.8%) due to cardiac failure, and nine (16.3%) early postoperative complications including subphrenic abscess, disruption of wound and pneumonia (one case of each), wound infection (three cases) and urinary tract infections (three cases). There were no complications related to the procedure itself. In a follow-up period of one to 12 years, neither cholangitis nor sump syndrome were documented.

The accuracy of various techniques for preoperative location of adrenal lesions was studied in 55 consecutive cases, and the perioperative course and outcome of surgery were analyzed. CT correctly located 94% of all adrenal tumours, was less accurate (42%) in hyperplasia and gave no false-positive results. Selective angiography revealed 75% of the tumours, but was likewise diagnostically inadequate in adrenal hyperplasia. Adrenal venous sampling correctly located 80% of tumours and of hyperplasia. In hyperplasia it was the single most successful procedure for detecting the site of adrenal hyperfunction. Phlebography gave misleading information in almost 45% of cases. The perioperative complications included splenic rupture necessitating splenectomy (3 cases), superficial wound infection (2), pneumonia (4) and subphrenic abscess (1). There were no perioperative deaths. The study indicated CT to be the principal procedure for preoperative location of adrenal disorders. In some cases with adrenal hyperfunction, venous sampling should be added. Adrenal surgery can be performed with low morbidity and no mortality and with favourable long-term outlook in cases of benign lesion.
