Between 1970 and 1980, 12 patients were admitted 16 times to San Bernardino County Medical Center for sigmoid volvulus. The seven men and five women averaged 68.5 years old. Sixty-seven per cent recounted histories of neuropsychiatric disorders. Fifty per cent had been institutionalized. Forty-two per cent had endured previous episodes of sigmoid volvulus. Fourteen of 24 nonoperative attempts at reduction were successful but were followed by nine recurrences. Ten of 12 patients eventually underwent surgery. Eight procedures were electively scheduled following spontaneous or nonoperative reductions. Two emergency procedures for gangrenous colons were required. Both of these patients died. Mortality following elective surgery was 25 per cent. Twenty-nine major complications followed the ten procedures. All ten patients underwent sigmoid resections. Follow-up disclosed only two living patients. Only five had survived one year following initial hospitalization and only two for two years. The high mortality of this and other American series was attributed to the frail nature of the elderly, debilitated, institutionalized patients with neuropsychiatric and multiple medical disorders, who develop sigmoid volvulus in the United States.

Simulium exiguum were collected in the San Antonio area on the Rio Micay as they blood-fed on a volunteer naturally infected with Onchocerca volvulus. The daily dissection of specimens revealed that delayed larval development was common and 23% of the larvae were abnormally formed. However, third-stage larvae were recovered by late day 5 (140 hours) following engorgement. It is concluded that S. exiguum is the vector of O. volvulus at this Colombian endemic focus even though its host efficiency is somewhat limited. S. metallicum collected near Cali from a naturally infected San Antonio volunteer was shown to be a relatively poor experimental host for O. volvulus.

The prevalence of onchocerciasis infection was determined in communities on 7 rivers located in the northern area of the canton San Lorenzo, province of Esmeraldas. Diagnosis of the infection was obtained by skin biopsies and recombinant-antigen based-serology. No evidence of infection was detected in 9 communities studied along the Rio Mataje, which forms the frontier between Ecuador and Colombia, nor in 10 adjacent communities located on 5 interior rivers. Evidence for Onchocerca volvulus infection was found in 4 communities on the Rio Tululvi with the following prevalence: La Boca (3.5% by biopsy and 3.9% by serology), Guayabal (9.1% by both biopsy and serology), La Ceiva (51.5% by biopsy and 53% by serology), and Salidero (4% by biopsy and 7.7% by serology). A few individuals in these communities were seropositive for O. volvulus in the absence of detectable dermal microfilariae: these might harbor very light or prepatent infections. No clinical disease attributable to onchocerciasis was found. The infected communities will be included in the ivermectin-based National Control Program for the disease, with no evidence of the infection having extended north of the Ecuadorian-colombian border.

Among 588 small bowel mechanical obstructions operated since January 1982 until December 1996 at the Flajani Surgery Department and Emergency Department of the San Camillo Hospital in Rome, 3 male patients were operated for intestinal obstruction due to Meckel's diverticulum. In one case, obstruction was caused by a small bowel volvulus rolling on a Meckel's diverticulum, whose gangrenous extremity was "blocked" on caecum. In the other two cases, intestinal loops were incarcerated into an internal hernial ring constituted by the same diverticulum whose inflamed extremity was fixed to corresponding mesentery. We examined embryologic and clinical aspects of the pathology here considered, particularly its complications, obstruction being the most common in adult age. Diagnosis is often misunderstood, since a complicated Meckel's diverticulum simulates many other abdominal pathologies. A straight radiography and an ultrasonography of the abdomen may be useful to reach the correct diagnosis. We performed diverticulectomy, using a linear stapler and we underline the opportunity of this method. In young age laparoscopy resection is considered the gold treatment of this pathology by some authors. We didn't observe any mortality, although one of our patients was in a severe septic condition. It is necessary to examine the last ileal 100 centimetres when a suspected acute appendicitis is not initially found by operation. The opportunity of a promptly performed operation is underlined to prevent that such a benign pathology may induce also exitus.

Acute gastric volvulus associated with congenital diaphragmatic hernia is an unusual surgical emergency. We describe a case of an 11-year-old girl who presented with a 4-day history of abdominal pain, nonproductive retching, cough, and shortness of breath. A chest radiograph revealed a large air-fluid level in left hemithorax and the presence of intestinal loops with marked mediastinal deviation. Nasogastric decompression was unsuccessful. Via a thoracoscopic approach, the large fluid-filled stomach was percutaneously decompressed but could not be reduced. Through a left subcostal incision, a left-sided diaphragmatic defect about 4 x 5 cm was encountered. A large portion of small intestines, ascending and transverse colon, strangulated but viable stomach, and a large spleen herniated through the defect. The contents were reduced, revealing a combined gastric volvulus. Once the diaphragmatic defect was repaired primarily, there was insufficient space in the abdominal cavity to contain all the viscera reduced form the chest. Therefore, we placed an AlloDerm patch on the fascia and closed with a wound V.A.C (Kinetic Concepts Inc, San Antonio, TX). Two weeks later, the wound was definitively closed; she recovered uneventfully and was discharged home 3 days later. To our knowledge, only 26 previous cases of acute gastric volvulus complicating a congenital diaphragmatic hernia in children have been reported in the literature. Our patient represents the 27th case and the first combined type acute gastric volvulus case.
