“…In the present study, we found two separate paraduodenal recesses, one due to the ascending branch of the left colic artery (arterial recess) and the other due to the inferior mesenteric vein (venous recess) (Figure 5). This hypothesis has been described by other authors [1, 5, 9]. Paraduodenal hernia was observed in 2 (16.66%) cases of the total number of paraduodenal fossae found in our study.…”

“…Treves suggested that the inferior duodenal fold is a remnant of the mesoduodenum, but Told describes these as fusion folds, caused by the process of physiological adhesions between the original left, afterwards anterior surface of the ascending part of the duodenum and the right or anterior surface of the descending mesocolon [4]. Several authors [1, 5, 9, 12] have observed peritoneal fossae, contributing to the discussion about their origin and relationship to congenital or acquired internal abdominal hernias. The process of formation of peritoneal fossae is not easy to explain.…”

“…The process of formation of peritoneal fossae is not easy to explain. According to Ancel and Cavaillon [5], the normal coalescence of the duodenum to the posterior parietal peritoneum would occur between its third and fourth part, and at the level of the duodeno-jejunal flexure, by means of two (inferior and superior) serous folds. These connect the duodenum horizontally to the serosa.…”

“…These authors [5] noted that the inferior duodenal fold was better developed than the superior one. The incidence of inferior duodenal fossa (52%) is almost double that of superior duodenal fossa (28%) found in the present study, which is a very significant difference.…”

“…The normal coalescence of the duodenum to the parietal peritoneum occurs between its 3 rd and 4 th parts, and at the level of the duodenojejunal flexure, by means of two serous folds, inferior and superior. The majority of internal hernias result from congenital anomalies of intestinal rotation and peritoneal attachment [5, 6]. …”

IntroductionThe detailed knowledge of the peritoneal recesses has great significance with respect to internal hernias. The recesses are usually related to rotation and adhesion of abdominal viscera to the posterior abdominal wall and/or the presence of retroperitoneal vessels which raises the serosal fold. The duodenal recesses are usually related to the 3rd and 4th parts of the duodenum. Internal hernias with respect to these recesses are difficult to diagnose clinically and usually noticed at the time of laparotomy. So, the knowledge of these recesses can be valuable to abdominal surgeons.Material and methodsThe present study was conducted in 100 cases including 10 cadavers, 45 post mortem cases and 45 cases undergoing laparotomy.ResultsWe found superior and inferior duodenal recesses in 28% and 52% respectively, paraduodenal in 12%, mesentericoparietal in 3%, retroduodenal in 2% and duodenojejunal in 18% of cases. Two abnormal duodenojejunal recesses were found, one on the right (instead of the left) of the abdominal aorta, and in the other the opening was directed upwards instead of downwards. The incidence of internal hernias was 3%.ConclusionsThus it was observed that there is low incidence of superior and inferior duodenal recesses, and high incidence of paraduodenal recess. The abnormal recesses might be due to malrotation of the gut. In laparotomy cases, the internal hernia was noticed when the abdomen was opened for intestinal obstruction. The incidence of internal hernia was found to be high.
