Spontaneous hernia through the posterior rectus abdominis sheath: case report and review of the published literature 1937-2008.

Spontaneous ventral hernia through the rectus abdominis sheath is perhaps the rarest hernia, with eight previously reported cases since 1937. The condition has not been reflected in the popular treatises on hernia. An 83-year-old male patient underwent surgery for intestinal obstruction. A spontaneous Richter's hernia of the small intestine through the posterior rectus abdominis sheath was successfully treated with bowel resection and tissue repair. Hernias of this variety are not well known and thus are rarely suspected. Their successful management is based on accurate emergency diagnosis and surgery, which we recommend as the best chance for a successful outcome.

Mondor's disease mimicking a Spigelian hernia.

Superficial thrombophlebitis of the thoracoepigastric veins (also known as Mondor's disease) is an uncommon disorder that typically affects middle-aged women and classically involves the chest wall including the breasts. Only one previously published, non-operative case of the disease, describes how the condition can resemble a strangulated Spigelian hernia. Herein we describe another similar case in which the diagnosis was made intra-operatively. The extremely unusual and similar clinical findings we observed demonstrate that Mondor's disease can occur in the Spigelian hernia belt and cause diagnostic confusion.

Subxiphoid incisional hernias after median sternotomy.

BACKGROUND: Subxiphoid incisional hernias are notoriously difficult to repair and are prone to recurrence. The few reports on subxiphoid hernia published over the last two decades have not fully addressed the etiology, pathology, treatment, and outcome of this problem. This review was performed to analyze the published experience and increase the understanding of these difficult hernias. METHODS: We reviewed the extensive literature, including the Medline and Current Contents computerized database searches, and searched the available bibliographies. RESULTS: Seven retrospective studies of a total of 113 patients who had clinical subxiphoid hernias after median sternotomy were found. An additional surgical technique describing a modified median sternotomy preventing the hernia, and a single review article on selected technical considerations of subxiphoid ventral repair were also found. CONCLUSIONS: The incidence of subxiphoid hernia after median sternotomy can be possibly reduced by paraxiphoid extension of the sternotomy, reinforcement near the xiphoid end of the incision, or by optimizing closure of the distal sternotomy and the linea alba. Abdominal wall reinforcement by open-mesh closure or laparoscopic transperitoneal prosthetic repair can effectively deal with the defect. Long-term outcome analyses are not yet available.

Neglected peritonsillar abscess resulting in necrotizing soft tissue infection of the neck and chest wall.

Necrotizing soft tissue infection (NSTI) of the neck and chest wall resulting from neglected peritonsillar abscess is a relatively rare but highly lethal surgical condition which has received little attention in the literature. The case of a 54-year-old male patient affected by this unusual infection is reported. Our recent experience and literature data suggest that NSTI resulting from peritonsillar abscess is rapidly spreading and life threatening. High index of suspicion, early diagnosis, broad-spectrum antibiotics and aggressive surgical debridement are essential to its successful treatment.

Mesenteric cystic lymphangioma: unusual cause of intra-abdominal catastrophe in an adult.

Mesenteric cystic lymphangiomas (MCLs) are rare benign cystic tumours of unknown aetiology, most often seen in paediatric patients. The clinical presentation is diverse, ranging from an incidentally discovered abdominal cyst to symptoms of acute abdomen. A 20-year-old male presented with generalised abdominal pain, nausea and vomiting of several hours duration following heavy lifting. Emergency laparotomy revealed a 15 x 10 x 8-cm pedicled cystic mass of the mid-ileal mesentery, causing a volvulus. The cyst and a 20-cm gangrenous intestinal segment were resected with anastomosis. The postoperative course was uncomplicated. MCLs should be included in the differential diagnosis of cystic intra-abdominal lesions. Even when asymptomatic and discovered incidentally, they must be treated surgically because of the potential to grow, invade vital structures and develop life-threatening complications.

Congenital posterolateral diaphragmatic hernia in an adult.

A Bochdalek hernia (BH) occurs when abdominal contents herniate through the posterolateral segment of the diaphragm. Most BHs present with life-threatening cardiorespiratory distress in the neonatal period. Rarely, hernias that remain clinically silent until adulthood present as life-threatening surgical emergencies. Our recent experience with a life-threatening emergency due to a BH in a 29-year-old male patient prompted us to reinforce that this entity does exist in adults and should be considered in the differential of acute abdominal pain.

Nonspecific ulcers of the colon.

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.

Trocar-site hernia complicated by necrotizing fasciitis--case report and review of the literature.

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.

Noninvasive characterization of myocardium after transmyocardial laser revascularization.

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.
