IntroductionIntestinal ischemia and reperfusion can impair anastomotic strength.The purpose of this study was to evaluate the safety of delayed colon anastomosis following remote ischemia-reperfusion (IR) injury.MethodsRats divided into two groups underwent bilateral groin incisions, however only the study group had femoral artery clamping to inflict IR injury. Twenty-four hours following this insult, the animals underwent laparotomy, incision of the transverse colon and reanastomosis. End points included anastomotic leakage, strength and histopathological features.ResultsAnastomotic leak among IR animals (22.2%) was not statistically different in comparison to the controls [10.5% (p = 0.40)]. Anastomotic mean burst pressures showed no statistically significant difference [150.6 ± 15.57 mmHg in the control group vs. 159.9 ± 9.88 mmHg in the IR group (p = 0.64)]. The acute inflammatory process in the IR group was similar to controls (p = 0.26), as was the chronic repair process (p = 0.88). There was no significant difference between the inflammation:repair ratios amongst the two groups (p = 0.67).ConclusionPrimary colon repair is safe when performed 24 hours following systemic IR injury.

Gallstone has rarely been described as a cause of gastrointestinal obstruction. However, the relative incidence of gallstone ileus increases significantly with age. The gastric outlet is very seldom the location of obstruction by a gallstone. The diagnosis of this condition is not difficult. Nevertheless, if treatment is delayed, high morbidity and mortality rates result. Comprehensive treatment aims to relieve the obstruction, to close the biliodigestive fistula and to prevent further gallbladder complications. The surgeon who deals with this type of illness should tailor the treatment plan according to the age, general condition, and intraoperative findings of the individual patient. This paper presents a case report of an 88-year-old woman with gastric outlet obstruction caused by a gallstone.
