Intestinal obstruction by giant Meckel's diverticulum. Case report

Most cases of Meckel’s diverticulum (MD) are asymptomatic and discovered by chance. Management of MD is controversial. The authors describe an exceptional case of intestinal obstruction caused by a giant MD in a patient who had previously undergone appendectomy. A review of the contradictory literature on this subject leads to the conclusion that careful consideration of clinical and morphological data (patient's age, ASA score, the surgical procedure to be performed, morphology and position of the MD, any fibrotic bands) is required before deciding whether or not to resect an asymptomatic MD.

Laparoscopic Duodenal-Jejunal Bypass for the Treatment of Duodenal Obstruction Caused by Annular Pancreas: Description of a Surgical Technique

Annular pancreas is a rare congenital anomaly, which is only surgically treated in symptomatic cases. Surgical treatment consists of bypassing the duodenal transit by gastrojejunal or duodenal-jejunal anastomosis. In the absolute majority of published cases, laparotomy is the most widely used access technique. The aim of this article is to report a case of an annular pancreas and describe the technical steps involved in carrying out a laparoscopic duodenal-jejunal anastomosis, for correction of the duodenal obstruction. The patient`s recovery was uneventful; she was discharged on the fourth postoperative day and remained asymptomatic for the 2-year, outpatient follow-up period. Laparoscopic duodenal-jejunal bypass is shown to be feasible and safe, and produce less surgical trauma, when carried out by an experienced surgeon who is duly trained and familiar with the laparoscopic technique.

Association of Intestinal Malrotation and Bochdalek Hernia in an Adult: a Case Report

Background Late presentations of congenital diaphragmatic hernia are rare and differ from the classic neonatal presentation. The association with other congenital malformations in children, mainly intestinal malrotation, is well documented. The diagnosis of this association in adults is very rare, and depends on a high degree of suspicion. Case presentation We report a case of a 50-year-old female Caucasian patient with a previous history of intestinal malrotation diagnosed in adolescence and treated conservatively. She was referred to the hospital with signs and symptoms of intestinal obstruction. The patient undertook computed tomography that confirmed small bowel obstruction with no obvious cause, and a right subphrenic abscess with right empyema was also present. An exploratory laparotomy was performed that revealed an intestinal malrotation associated with a right gangrenous and perforated Bochdalek hernia. Resection of the affected small bowel, closure of the Bochdalek foramen and the Ladd procedure were carried out. Conclusion This case shows a rare association of two rare conditions in adults, and highlights the challenge in reaching the diagnosis and management options.

Oclusão Intestinal. Experiência da Urgência do H.S.José 1981-1991

Os Autores descrevem a experiência, em oclusão intestinal, da Unidade de Urgência Cirúrgica dos Hospitais Civis de Lisboa (UUC-HCL), no período de 10 anos, decorrido entre Novembro de 1981 e Novembro de 1991, estimando que esta entidade patológica tenha constituído cerca de 15% da casuística de cirurgia geral daquele Serviço. Os dados referentes aos 3679 doentes, operados de urgência por oclusão intestinal, foram reunidos num ficheiro informatizado e a sua análise global é descrita recorrendo à representação gráfica dos elementos mais relevantes. Foi semelhante a distribuição por sexos : feminino (49%) e masculino (5 1%). A forma mecânica de oclusão (94%)teve como patologias mais frequentes: a hérnia estrangulada (1604 casos), a brida (568 casos) e o cancro (713 casos); e a forma dinâmica ou funcional (6%) teve, como principal ocorrência, a isquémia intestinal (143 casos). A terapêutica cirúrgica foi avaliada de forma geral. No entanto, comenta-se, brevemente, a evolução registada no tratamento primário do cancro colorrectal em oclusão (625 casos). A taxa de mortalidade global foi de 10,8% (adulto). Em termos relativos, teve como principais expressões: (39%) na isquémia intestinal, (23%) no cancro e (22%) no volvo intestinal.

Prenatal ultrasonographic detection of gastrointestinal obstruction: results from 18 European congenital anomaly registries.

OBJECTIVES: We evaluated the prenatal detection of gastrointestinal obstruction (GIO, including atresia, stenosis, absence or fistula) by routine ultrasonographic examination in an unselected population all over Europe. METHODS: Data from 18 congenital malformation registries in 11 European countries were analysed. These multisource registries used the same methodology. All fetuses/neonates with GIO confirmed within 1 week after birth who had prenatal sonography and were born during the study period (1 July 1996 to 31 December 1998) were included. RESULTS: There were 670 793 births in the area covered and 349 fetuses/neonates had GIO. The prenatal detection rate of GIO was 34%; of these 40% were detected < or = 24 weeks of gestation (WG). A total of 31% (60/192) of the isolated GIO were detected prenatally, as were 38% (59/157) of the associated GIO (p=0.26). The detection rate was 25% for esophageal obstruction (31/122), 52% for duodenal obstruction (33/64), 40% for small intestine obstruction (27/68) and 29% for large intestine obstruction (28/95) (p=0.002). The detection rate was higher in countries with a policy of routine obstetric ultrasound. Fifteen percent of pregnancies were terminated (51/349). Eleven of these had chromosomal anomalies, 31 multiple malformations, eight non-chromosomal recognized syndromes, and one isolated GIO. The participating registries reflect the various national policies for termination of pregnancy (TOP), but TOPs after 24 WG (11/51) do not appear to be performed more frequently in countries with a liberal TOP policy. CONCLUSION: This European study shows that the detection rate of GIO depends on the screening policy and on the sonographic detectability of GIO subgroups.

Chronic intestinal pseudoobstruction and ophthalmoplegia in a patient with mitochondrial myopathy

A 38 year old woman having chronic intestinal pseudoobstruction associated with mitochondrial myopathy is reported. The clinical and radiographic features suggested the diagnosis of chronic intestinal pseudoobstruction. Muscular atrophy and ophthalmoplegia led to muscle biopsy, which disclosed accumulation of normal and abnormal mitochondria ('ragged red fibres'), characteristic of mitochondrial myopathy.
