Open pelviperineal trauma.

The authors present their results in the management of 48 patients with complex pelviperineal injuries treated at the Surgical Emergency Ward of the University of São Paulo School of Medicine General Hospital. The distinct factors influencing the morbidity and mortality rates are discussed as well as the importance of an aggressive treatment in the initial approach of these patients. The following steps are virtually essential for the achievement of results comparable to those presented in the present protocol: exhaustive irrigation of the perineal wound with saline solution followed by surgical debridement and removal of all devitalized areas, maintenance of the wound open, early maturation transverse colostomy with total fecal flow diversion, periodic surgical revisions at intervals of 24 to 72 hours, large doses of antibiotic therapy, nutritional support with full parenteral feeding, and appropriate management of bone injuries and skin grafts. Adopting of measures proposed in this protocol yielded a decrease in mortality rate from 70% to 31.5%.

Gallstone ileus resulting in strong intestinal obstruction.

Mechanic intestinal obstruction, caused by the passage of biliary calculus from vesicle to intestine, through fistulization, although not frequent, deserve study due to the morbi-mortality rates. Incidence in elder people explains the association with chronic degenerative diseases, increasing complexity in terms of therapy decision. Literature discusses the need and opportunity for the one or two-phase surgical attack of the cholecyst-enteric fistule, in front of the resolution on the obstructive urgency and makes reference to Gallstone Ileus as an exception for strong intestinal obstruction. The more frequent intestinal obstruction observed is when it occurs a Gallstone Ileus impacting in terms of ileocecal valve. The authors submit a Gallstone Ileus manifestation as causing strong intestinal obstruction, discussing aspects regarding diagnostic and treatment.

Gallstone ileus as a cause of upper intestinal obstruction.

Gallstone ileus, a mechanical intestinal obstruction caused by the passage of a gallstone into the intestinal lumen through a fistula, although not common, deserves to more carefully studied due to its morbidity and mortality. Its incidence among older-age groups explains its association with chronic and degenerative diseases, which increase the complexity of the treatment choice. The need and appropriateness of a surgical approach to a cholecystenteric fistula to solve the obstructive emergency, in a one or two stage procedure, has been discussed in the literature. It has also been reported that gallstone ileus is an uncommon cause of upper intestinal obstruction. Intestinal obstruction is seen more frequently after a gallstone impacts at the ileocecal valve. The authors report a case of gallstone ileus as a cause of upper intestinal obstruction and discuss its diagnosis and treatment.

[Fournier syndrome: evaluation and initial treatment].

The records of 48 patients with Fournier's syndrome (FS) treated at the Emergency Surgical Service of the Hospital das Clínicas of the University of São Paulo Medical School in the period 1982-1991 were reviewed. Clinical and laboratory data at admission were analysed. The following factors were statistically significant when associated with bad prognosis: elevated serum creatinine, hypoxemia, metabolic alkalosis or acidosis, diabetes and age over 50 years. Based on these five criteria, the patients were divided into two groups: Group I, mild FS (32 cases) and Group II, severe FS (16 patients). This classification permits a better planning of therapy. In cases classified as severe, treatment should include wide débridement, with resection of all necrotic tissues, scheduled reoperations for further débridements, transverse colostomy, wide spectrum antibiotic therapy and total parenteral nutrition. In the mild cases, the patients may be treated with débridement and antibiotics only.

[Traumatic rectal injuries].

The authors review the cases of traumatic rectal injuries admitted to the Emergency Service of the "Hospital das Clínicas", University of São Paulo Medical School, during the period of July 1981 to July 1988. Forty-five patients (62.5%) had their injuries due to gunshot, 14 (19.4%) due to foreign bodies on the rectum, 10 (13.8%) due to blunt trauma and 3 (4.1%) due to stab wounds. The intraperitoneal rectum was injured in 32 patients (44.4%) and extraperitoneal portion of the rectum in 40 patients (55.5%). On the intraperitoneal injuries the management adopted were simple suture (14 patients), associated with a colostomy (17 patients) and in one patient the Hartmann procedure was adopted. On the extraperitoneal wounds the management adopted were rectal repair (when feasible), colostomy, distal washout and drainage. The complications rate was 27.8%, and from them, the majority (70%) were related to infectious nature. Seven patients died (9.7%), four of them as a consequence of sepsis. The morbidity and mortality of the rectal injuries were closed related to infectious complications as a consequence of late diagnosis. For this reason, the authors consider that all efforts should be employed to establish the prompt diagnosis.

[Traumatic wounds of the esophagus].

Thirty four (75.5%) individuals sustained gunshot wounds, nine (20%) stab wounds, while two (4.4%) suffered blunt trauma. Thirty four patients (75%) displayed severance of the cervical portion of the esophagus, seven (15.5%) of the thoracic segment and only four (8.8%) had injuries on the abdominal portion. The cervical esophagus was surgically approached through oblique left side cervicotomy with primary suture and drainage with Penrose drain. A postero-lateral right side thoracotomy was employed for lesions of the upper and intermediate portion of the thoracic esophagus. When the lower portion of the esophagus was injured, a left side thoracotomy was employed. When the injury involved less than half of the perimeter of the esophagus suturing with ample drainage was adopted. In more extensive injuries involving over half of the perimeter total esophagectomy was the treatment of choice. In abdominal esophageal injuries laparotomy, suture and drainage were performed. Complications occurred in 40% of all patients. Seven patients died though only one from direct consequences of the esophageal injury. The authors believe that an early surgical approach for traumatic esophageal injuries is the best procedure. Primary suture and drainage score the best results. Other measures (esophagectomy, esophagostomy, gastrostomy) should be adopted only when the injury is either extensive or mediastinal contamination is present.

[Perforated duodenal diverticulum: a report of 2 cases].

Two cases of perforated duodenal diverticulum, treated at the surgical Emergency Service of the Hospital das Clínicas of the University of São Paulo Medical School are reported. Although duodenal diverticula are frequent their perforation in is a rare and dougerous complication. Diagnosis and surgical treatment are discussed. We believe that excision, primary suture with an omental patch and drainage are procedures of choice for the treatment of this complication.

[Complex pelviperineal injuries: systematization of the treatment].

The authors review the cases of complex pelviperineal injuries admitted to the Emergency Service of the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the period 1983-1988. The management of these patients followed a protocol that consisted of: exhaustive lavage of the injury with extensive debridement, leaving the wound widely unsutured, matured loop colostomy, lavage of the distal colon, scheduled revisions at 48 to 72 hour intervals, intensive antibiotic treatment and early total parenteral nutrition. Thirty one patients were treated following these procedures, with a decrease in mortality due to sepsis from 50% to 16.1%.

[A fatal case of lower gastrointestinal hemorrhage: report of case and review of the literature].

Gastrointestinal hemorrhage continues to be a major medical problem. Even with improvements in both diagnostic and therapeutic, a significant number of patients still require surgical intervention for control of hemorrhage. When the source of persistent lower gastrointestinal hemorrhage is unknown, subtotal colectomy is a conceptually rational management choice. The authors present a case of massive lower gastrointestinal hemorrhage with unusual fatal outcome. A review of literature of this condition and a discussion about the diagnosis, treatment and etiopathogenesis are presented.

[Postsplenectomy gastric fistula: report of a case].

Gastric perforation following splenectomy is a rare complication occurring in less than 1% of patients and it is mainly associated with iatrogenic injury to the greater curvature of the stomach. The authors report a case of gastric fistula in a patient who underwent splenectomy for blunt abdominal trauma and discuss the main etiopathogenic and diagnostic aspects.

[Traumatic rupture of the diaphragm: study of 35 cases].

A retrospective review of 35 patients with diaphragmatic injury attended at the Emergency Service of the Hospital das Clínicas, University São Paulo is analysed. Diagnosis was made through chest roentgenogram (48.5%), peritoneal lavage (37%) and contrast studies (14.5%). The most common extra-abdominal lesion were due to head, pelvic and thoracic trauma. Thirty-one patients sustained injuries to the left-side and four to the right. Associated intra-abdominal injury occurred in 89% of them. Retroperitoneal haematoma, spleen and liver injury were the most frequent lesions. All cases were treated by laparotomy, pleural space irrigation through the diaphragmatic lesion, thoracic drainage and suture of the injury. The morbidity rate was 40% and deaths occurred in 22.8%. Based upon these data, we concluded: the mechanism of trauma, chest RX findings and pelvic fracture are important clues for early recognition; irrigation of pleural space seems to be important in order to prevent empyema. Despite of this, the mortality remains high.

[Abdominal surgical emergencies in patients with acquired immunodeficiency syndrome].

UNLABELLED: Patients with Acquired Immunodeficiency Syndrome (AIDS) may present acute abdomen with modified clinical manifestations which may lead to errors and delays in preoperative diagnosis, with frequent delays in treatment. PURPOSE: To study clinical signs, diagnostic criteria, etiology, surgical management and mortality in patients with AIDS submitted to exploratory laparotomy. METHODS: We reviewed the records of thirty-one AIDS patients admitted in the period 1986-1993 at the Emergency Surgical Service--Hospital das Clínicas, University of São Paulo submitted to exploratory celiotomy due to acute abdome. RESULTS: Abdominal pain was the most frequent symptom and the diagnosis of acute abdome was made based upon physical examination, laboratory tests and imaging techniques. Gastrointestinal tract perforation was the most frequent cause of acute abdome, mainly due to Cytomegalovírus infection. All patients presented postoperative complication, specially wound infection. Mortality rate was 42% due to sepsis and multiple organ failure. CONCLUSION: Based upon these data we conclude that: AIDS patients usually present masked clinical signs of acute abdomen; stomas should be formally indicated. Mortality is extremely high due to immunocompromised state, delayed diagnosis and treatment and non therapeutic celiotomies.
