Abstract Introduction: We dissected and described the macroscopic anatomy of the gastrointestinal tract of the donkey. Materials and Methods: Eleven domestic donkeys of both sexes from Tunisia were used for this study. Results: Although statistically insignificant, length values of the gastrointestinal tract pertaining to the females were generally higher than those pertaining to the males. The ostium cardiacum was very narrow and its diameter was 4.42 ± 0.57 mm in the males and 6 ± 1.22 mm in females. In the first part of the duodenum, we found papilla duodeni major and papilla duodeni minor. Both papillae were located very near to each other with a distance less than 1 cm and very near to the ostium pyloricum. The cecum was divided in parts of basis, corpus and apex. Three flexures divided the ascending colon into four parts: right ventral, left ventral, left dorsal and right dorsal. The cecum, left ventral colon and right dorsal colon had more evident sacculations (Haustra ceci and coli) (Figure 5). Teniae numbers were constant in all animals as 4, 4, 4, 1, 3 and 2 for cecum, right ventral colon, left ventral colon, left dorsal colon, right dorsal colon and descending colon, respectively. Conclusion: Although the gross anatomy of the intestines of the donkey was similar to the domestic horse in general, we detected some differences between these equine species.

Carl Florian Toldt was an Austrian anatomist who made meaningful contributions worldwide and defined what is one of the most important surgical landmarks in abdominal surgery. Through his research studies, the embryologic dissection plane known as the “White Line of Toldt” represents an important anatomical landmark that helps to mobilize either the ascending or descending colon. His career spanned over 45 years, beginning in Verona and continuing to Prague and Vienna. He was an author of several innovative books and scientific articles regarding micro- and macroscopic anatomy. In addition, he received numerous recognitions and prizes for his work, making him an essential figure in the medical scientific community. Even a street in Vienna, Karl-Toldt-Weg, is named in his honor. The purpose of this historical article is to celebrate and honor Toldt 100 years following his death, remembering his scientific contributions to the medical and surgical fields and giving thanks for his numerous accomplishments. This article brings light to the man behind the eponym.

Abstract Background This study aimed to compare fecal calprotectin (FC) levels with other commonly used parameters as part of patient care during evaluation for inflammatory bowel disease (IBD). Methods We recruited adult IBD patients with ulcerative colitis (UC) and Crohn’s disease (CD) and compared the results of the patient’s biopsy results (i.e., inflamed versus noninflamed) for six sites (i.e., ileum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum) with concentrations of C-reactive protein (CRP), total leucocytes and fecal calprotectin (FC). Results We found that FC was significantly elevated in a concentration-dependent manner that correlated with the number of active inflammation sites reported in biopsy. Although CRP and leucocyte measurements trended upwards in line with inflammation reported from biopsy, the results were highly variable and highlighted poor reliability of these biomarkers for indicating IBD inflammation. Conclusions These results strongly suggest that FC correlates best with biopsy reports and is a superior marker than CRP and leucocytes.

Potorous Tridactylus

The gastric distribution of barium sulphate and its subsequent intestinal passage were examined by radiography in Potorous tridactylus. Barium sulphate administered in association with solid food passed to the sacciform forestomach from the tubiform forestomach. However, ingested barium sulphate suspension mainly entered the hindstomach via the gastric sulcus. Barium sulphate which entered the sacciform forestomach remained for no more than 1 h before passing to the hindstomach via the tubiform forestomach. The passage of contrast medium through the intestine was followed in adults administered barium sulphate suspension only. Contrast medium which entered the hindstomach was not detectable there after 10 min. Barium sulphate first arrived at the caecum and proximal colon after 20 min, and by 45 min the majority had reached these organs. It persisted in the caecum and proximal colon for several hours, during which there was some movement into the descending colon and rectum. These results lead towards a new interpretation of the role of the potoroine foregut and hindgut.

PURPOSE: To elaborate an animal model with the objective of studying the continence of the biological valves surgically performed in the left colon of rats. METHODS: Thirty four rats were operated on and divided into three groups (G). G1 (sham) animals which underwent laparotomy only; G2 (perineal amputation without valves): animals which underwent amputation of the anal sphincter complex combined with a perineal colostomy; G3 (abdominoperineal amputation combined with valves): animals which underwent abdominoperineal amputation combined with three, equidistant and circumferential (360(0)), extra-mucosal seromyotomies, of the descending colon, which were sutured to create biological valves combined with perineal colostomy. Animals were euthanized in the late postoperative period and surgical valves were saved for histopathological study. RESULTS: Surgical procedure provoked intestinal dilation, as well as segmented chambers along the descending colon. Retained fecalomas between the valves and proximal to them were also noted. Six rats died of intestinal obstruction due to fecal impaction at the surgical site. The sequence of events was: stasis, obstruction, distention, perforation, peritonitis and death. Histopathology showed inflammation due to foreign body type reaction around the sutured colon causing partial concentric stenosis, capable of interfering normal mechanical activity of the distal colon. This process resulted in retardation of the intestinal transit. CONCLUSION: Extra-mucosal seromyotomies, with seromuscular suture, can be used as an operative procedure capable of causing retardation in the intestinal transit of rats.

Resected Case

The entity known as “juvenile-like (inflammatory/hyperplastic) mucosal polyps of the gastrointestinal tract in neurofibromatosis type 1 (NF1)” was recently proposed, but is not well known. Here, we describe the characteristics of this entity in a surgically resected case. The hemorrhagic 2 × 1 cm–sized polyp was resected from the ascending colon of a 55-year-old male NF1 patient. The polyp was composed of characteristic multiple mucosal protrusions and submucosal elements that included vasculopathic changes. Histologically, this lesion was similar to an inflammatory fibroid polyp rather than juvenile or hyperplastic polyps. This disease could be a distinct entity, and “inflammatory vasculopathic polyp” would be a suitable name.

ABSTRACT The location and abundance of Campylobacter jejuni and Campylobacter lanienae in the intestines of beef cattle were investigated using real-time quantitative PCR in two studies. In an initial study, digesta and tissue samples were obtained along the digestive tract of two beef steers known to shed C. jejuni and C. lanienae (steers A and B). At the time of slaughter, steer B weighed 540 kg, compared to 600 kg for steer A, yet the intestine of steer B (40.5 m) was 36% longer than the intestine of steer A (26.1 m). In total, 323 digesta samples (20-cm intervals) and 998 tissue samples (3.3- to 6.7-cm intervals) were processed. Campylobacter DNA was detected in the digesta and in association with tissues throughout the small and large intestines of both animals. Although C. jejuni and C. lanienae DNA were detected in both animals, only steer A contained substantial quantities of C. jejuni DNA. In both digesta and tissues of steer A, C. jejuni was present in the duodenum and jejunum. Considerable quantities of C. jejuni DNA also were observed in the digesta obtained from the cecum and ascending colon, but minimal DNA was associated with tissues of these regions. In contrast, steer B contained substantial quantities of C. lanienae DNA, and DNA of this bacterium was limited to the large intestine (i.e., the cecum, proximal ascending colon, descending colon, and rectum); the majority of tissue-associated C. lanienae DNA was present in the cecum, descending colon, and rectum. In a second study, the location and abundance of C. jejuni and C. lanienae DNA were confirmed in the intestines of 20 arbitrarily selected beef cattle. DNA of C. jejuni and C. lanienae were detected in the digesta of 57% and 95% of the animals, respectively. C. jejuni associated with intestinal tissues was most abundant in the duodenum, ileum, and rectum. However, one animal contributed disproportionately to the abundance of C. jejuni DNA in the ileum and rectum. C. lanienae was most abundant in the large intestine, and the highest density of DNA of this bacterium was found in the cecum. Therefore, C. jejuni colonized the proximal small intestine of asymptomatic beef cattle, whereas C. lanienae primarily resided in the cecum, descending colon, and rectum. This information could be instrumental in developing efficacious strategies to manage the release of these bacteria from the gastrointestinal tracts of cattle.
