The ileosigmoid knot is a rare surgical emergency. It is an unusual type of bowel obstruction in which the ileum usually wraps around the base of the sigmoid colon and forms a pseudoknot. It is usually associated with difficult preoperative diagnosis and poor surgical outcome. To analyze the clinical presentations, operative findings, management, postoperative complications and outcome of patients with ileosigmoid knotting. A retrospective analysis of nine cases of ileosigmoid knotting over a 6-year period from July 2005 to May 2011. Ileosigmoid knotting was common in males in the fifth decade. Mean duration of symptoms prior to admission was 42.67 h. Both the ileum and the sigmoid colon were gangrenous in all the patients. Mortality was 22.22 %. The mean duration of hospital stay was 13.67 days. To conclude, ileosigmoid knotting, though a rare cause of intestinal obstruction, carries a significant risk of mortality. In our study, ileostomy along with colorectal anastomosis seemed to be a better and safer alternative than primary repair in the management of ileosigmoid knotting. Awareness of this condition among surgeons will help to reduce the morbidity and mortality associated with this unusual form of intestinal obstruction.

Crohn's Disease is a chronic, idiopathic, transmural inflammatory disease affecting predominantly distal ileum, the common presentation include stricture and fistula formation. Free perforation in the peritoneal cavity is rare. To study the presentation and management of Crohn's perforation. A retrospective study of 9 cases of perforative peritonitis later diagnosed due to Crohn's disease on histopathological examination. Among the 9 patients, 8 were males and 1 was female. The ages of the patients ranged from 30 to 58 years, with mean age of 41.8 years. 6 patients were in the age group of 30-45 years. 8 patients were not known to be suffering from Crohn's. Resection followed by anastomosis was done in 4 cases including the case of known Crohn's, while resection follwed by end illeostomy with mucous fistula was done in remaining cases. Resected specimens were sent for histopathological examination in all cases. Though Crohn's perforation is rare it should be kept in mind when dealing with single or multiple perforation of the small intestine even in the developing countries. Though the number of cases in our series are too few to come to a conclusion, we found that illeostomy sems a prudent alternative to traditional resection anastomosis.
