Nonspecific colonic ulcers (NSCUs) are rare and potentially life-threatening lesions of unknown etiology; the diagnosis is based on histologic findings showing nonspecific inflammatory changes. The condition's variable symptoms can include nonspecific abdominal discomfort, gastrointestinal bleeding, perforation, and peritonitis. Radiologic imaging can be helpful in locating the lesions, but colonoscopy facilitates early definitive diagnosis and aggressive treatment. The potential of NSCUs to recur is currently unknown, and morbidity rates remain high. Long-term colonoscopic follow-up may improve the prognosis.

Only a few reports have been published describing necrotizing soft tissue infection (NSTI) following laparoscopic surgery; none identify trocar-site hernia as an etiologic factor. We present a case report and review of the literature. A 43-year-old previously healthy man underwent uneventful laparoscopic cholecystectomy. An unrecognized strangulated lateral trocar-site hernia resulted in fatal NSTI. A Medline database search (1966-2002) identifies ten detailed reports of NSTIs following laparoscopic surgery. Multiple risk factors were identified in almost all patients. The mortality rate was 20%. Patient survival from NSTI requires early recognition, aggressive surgical intervention, and intensive medical care. NSTI can occur following minimally invasive surgery, and physicians should maintain a high index of suspicion when patients begin to develop postoperative symptoms. Trocar-site hernia arises as another etiologic factor for NSTI in the domain of minimally invasive surgery.

AIM: The therapeutic mechanism of transmyocardial revascularization (TMR) is not yet fully understood, and continues to be a subject of controversy and active research. Immediate direct laser channel flow, gradual angiogenesis, denervation, and perioperative infarction of the ischemic area have been all discussed, without clear evidence indicating superiority of individual factors. METHODS: We utilized a prospective noninvasive physiologic dynamic method to assess laser-related myocardial injury. The study protocol included EKGs and echocardiograms, including intraoperative transesophageal echocardiograms (TEE) on consecutive TMR patients. CPK-MB was measured postoperatively, with 5 samples at 6-hour intervals. RESULTS: Fifty male patients averaging 62 years old were enrolled in the study. Two patients experienced postoperative myocardial infarctions, from which 1 died. The average CPK-MB values were 12.8+/-1.28 immediately after surgery, 19.2+/-2.4 at 6 h, 15.2+/-2.3 at 12 h, 12.2+/-6.3 at 18 h, and 11.7+/-1.3 at 24 h. In only 5 patients were the CPK-MB values over 30 units at their peak. The intraoperative wall motion remained unchanged in the patients studied, both using TEE and transthoracic echography. CONCLUSION: Significant myocardial injury after TMR appears unlikely, as indicated by CPK-MB and myocardial wall dynamics. Furthermore, TMR does not seem to aggravate baseline myocardial ischemia. We found no evidence to support a hypothesis that surgical myocardial injury constitutes the mechanism of therapeutic action in TMR.

Pericardial cystic lesions (PCLs) occur infrequently but are significant for their varying clinical presentation and pathological multitude. A review of the literature (including Medline and Current Contents database searches, and search of existing bibliographies) finds confusion in nomenclature and an absence of appropriate classification. A new classification system is proposed based on exo- or endophytic growth, presence of adhesions, and compression of myocardium or great vessels. A multitude of pathological entities with diverse pathogenesis, disease courses, and prognoses may present as PCLs. Detailed knowledge of lesion types and alternatives among diagnostic and therapeutic options permits a selective approach to patient management. The usefulness of a unified classification system should be evaluated in a substantial patient population, with detailed statistical analysis.

Spigelian hernias (SHs) are rarely observed among children. The diagnosis is not difficult to make once it has been considered. The condition requires a high index of suspicion because of its high potential for life-threatening complications. A 12-year-old boy underwent open appendectomy for presumed acute appendicitis. A normal appendix found at laparotomy suggested another etiology for the acute abdomen. Incarceration of the greater omentum in a spigelian hernia was found, and the hernia repaired. The repair of pediatric SH is straightforward and utilizes endogenous tissues. Patients should be followed up for as long as possible to develop data on the durability of the repair technique selected.

BACKGROUND: The underlying risk associated with visceral mesh erosion is the close opposition of adjacent intestines to the prosthetic graft. This highly morbid condition has been described with most types and techniques of abdominal wall mesh repair. PATIENT: We report the case of a 52-year-old man who presented with an entero-colocutaneous fistula 10 years after prosthetic mesh repair of an incisional hernia. The fistula was excised and the abdominal wall defect repaired with a tissue-impervious composite. CONCLUSIONS: The use of a tissue-impervious barrier avoids development of enteric fistula when a prosthesis is placed directly over the viscera.

Parapubic hernia is considered rare, with 18 hernias described in five articles published since 1971. The hernia results from iatrogenically or traumatically detached rectus abdominis muscles at the pubic bone and presents a therapeutic challenge because there is no strong aponeurotic anchoring structure in the defect's caudal aspect. We describe a patient with a large parapubic hernia repaired by a combined preperitoneal and onlay prosthetic method. This report adds another dimension to the prosthetic repair options in parapubic hernias and illustrates the effectiveness of the tension-free repair principle in their definitive management.

Necrotizing soft tissue infection (NSTI) of the chest wall is a relatively rare but highly lethal surgical infection which has received little attention in the medical and surgical literature. The data reported are based on a literature review, including a Medline database search, and search of existing bibliographies. Twenty well-documented cases of primary chest wall involvement by NSTI were found. Thirteen patients were male. Patients' ages ranged from 10 weeks to 78 years. Thirteen patients were postoperative (65%). The diagnosis was initially considered in only 3 of the postoperative cases, a cause of significant delays in surgical treatment. Among those who lived long enough for their wounds to close, 2 had secondary healing, 5 experienced delayed skin grafting over the granulating wound, and 1 had skin grafting combined with muscle transfer. Mortality was 60%. Chest wall NSTI is a rapidly spreading, highly lethal infection. A high index of suspicion, early diagnosis, and aggressive approach are essential to its successful treatment.

Traumatic hernia resulting from blunt impalement of the abdominal wall, known as "handlebar hernia," is seldom addressed in the surgical literature, with only 28 previously reported cases. We describe our experience with this rare traumatic hernia diagnosed by physical examination and confirmed by ultrasonography. Published reports suggest handlebar hernia's potential for serious underlying injury and the diagnostic importance of computed tomographic scanning. The case presented here demonstrates the value of bedside ultrasonography in diagnosis confirmation and surgical planning for this condition.
