Does preoperative enhanced CT predict requirement of intestinal resection in the patients with incarcerated myopectineal hernias containing small bowel?

PURPOSE: Bowel wall enhancement on CT imaging is considered one of the useful features for the prediction of the presence of irreversible ischemic change in patients with small bowel obstruction. However, the applicability of CT imaging in patients with incarcerated hernias has not been investigated in detail. The aim of this retrospective study was to evaluate the feasibility of preoperative CT findings for the prediction of the presence of irreversible ischemic change in patients with incarcerated hernias containing small bowel. METHODS: Included in this study were 76 patients who underwent surgery for preoperatively diagnosed incarcerated hernias containing small bowel (27 inguinal hernias, 37 femoral hernias and 12 obturator hernias) at our hospital between January 2011 and June 2020. The preoperative clinicoradiological features were compared between the groups, and predictors for intestinal resection were evaluated. RESULTS: Nineteen patients required intestinal resection (Resection group), and the other 57 patients did not require intestinal resection (Nonresection group). Multivariate analyses revealed that age ≥ 80 years (p = 0.018, odds ratio = 6.604) and the absence of bowel wall enhancement (p = 0.032, odds ratio = 51.200) were independent predictors for intestinal resection. In resected specimens, all patients with an absence of bowel wall enhancement on preoperative enhanced CT had ischemic changes extending beyond the muscularis propria. CONCLUSIONS: Preoperative enhancement CT yields useful information for the prediction of the presence of irreversible ischemic change in patients with incarcerated hernias containing small bowel.

Laparoscopic repair is a treatment of choice for selected patients with incarcerated obturator hernia.

PURPOSE: The feasibility and potential advantages of laparoscopic diagnosis and repair of incarcerated obturator hernia (OH) is debated. The aim of this retrospective study was to compare short-term complications comparing laparoscopic to open repair of OH. METHODS: A total of 29 preoperatively diagnosed patients underwent surgery for a preoperatively diagnosed OH between January 2006 and July 2017. The patients were divided into a laparoscopic group (11 patients underwent laparoscopic repair; 8 without and 3 with intestinal resection) and an open group (18 patients who underwent open repair; 9 without and 9 with intestinal resection).The outcomes were compared between groups. A risk factor analysis for postoperative complications was performed. RESULTS: The incidence of postoperative complications was fewer in the laparoscopic group [9.0% vs. 61.1%; (p < 0.001)]. The bleeding amount [1.2 g vs. 40.4 g; (p = 0.087)] and postoperative length of stay [13.3 days vs. 17.1 days; (p = 0.072)] showed a tendency to be favorable in the laparoscopic group. Occult contralateral OH was detected in three patients (27.7%) in the laparoscopic group and one patient (5.5%) in the open group (p = 0.099). Open surgery and intestinal resection were independent risk factors for a postoperative complication. One patient in the open group developed an incarcerated OH on the contralateral side 1 year after the first surgery. CONCLUSIONS: Laparoscopic repair for incarcerated obturator hernia demonstrated more favorable short-term outcomes compared with open repair in terms of a lower incidence of postoperative complications and it was potentially beneficial for detecting and repairing an occult OH on the contralateral side.

Angiomatous lesions of glans penis.

Two patients with an angiomatous lesion of the glans penis are presented. These lesions are rare and difficult to distinguish from the spongiosum tissue. There is much controversy concerning their true nature, i.e., whether they represent a true neoplasm, herniation of the corpus spongiosum, or vascularization of a hematoma or thrombus. The present lesions were not true neoplasms, but are best described as malformative lesions.
