Randomized Controlled Trial Comparative Study
[Postoperative metabolic acidosis: use of three different fluid therapy models].
Intraoperative fluid administration is considered an important factor in the management of metabolic acidosis following surgical procedures. The aim of this study was to compare three types of intraoperative infusional models in order to evaluate their effect on acid-base changes in the immediate postoperative period as calculated by both the Henderson-Hasselbach equation and the Stewart approach. Forty-seven patients undergoing left hemicolectomy were enrolled in the study and assigned randomly to receiving 0.9% saline alone (Group A, n=16), lactated Ringer's solution alone (Group B, n=16) or 0.9% saline and Ringer's solution, 1:1 ratio (Group C, n=15). ⋯ The results showed a metabolic acidosis status in Group A patients, whereas Group B exhibited metabolic alkalosis only by means of the Stewart method. No difference was found in Group C between the time points t0 and t1 when using either the Henderson-Hasselbach equation or using the Stewart model. We conclude that saline solution in association with Ringer's solution (1:1 ratio) appears to be the most suitable form of intraoperative fluid management in order to guarantee a stable acid-base balance in selected surgical patients during the immediate postoperative period.

Traumatic hernia of the abdominal wall is a rare type of hernia. A high-energy, localised impact causes the disruption of the abdominal wall musculature without penetrating the skin. ⋯ A high level of clinical suspicion is required for diagnosis because of the high rate of associated injuries. The authors report a case of handlebar hernia managed successfully by surgical repair.

Traumatic lesions involving the rectum, perineum and anus are infrequent but difficult to treat, requiring experience with trauma and colo-proctological surgery. The aim of the treatment is to repair the lesions and to minimise the early complications which are the main cause of failure and of late complications and disability. The most complicated lesions present problems concerning either the surgical strategy or the surgical timing, both of which are essential for a successful outcome. ⋯ Only two cases (28.6%) of early complications and one case (14.3%) of persistent minimal sphincter dysfunction occurred. On the basis of these good results, the clinical experience and the literature, the Authors suggest that these perineo-ano-rectal lesions, though often complex, may often be cured by early surgery, confining colostomy only to particular cases. In addition to experience with trauma and the timing of colo-proctological surgery, a knowledge of all the available surgical options is mandatory to achieve the best results.

Review Case Reports
Splenic rupture after colonoscopy. A case report and review of the literature.
Rupture of the spleen after colonoscopy is a rare but dangerous complication; up to now only a few cases have been reported in the literature. This complication is more frequent in patients who have previously undergone abdominal surgery and after operative colonoscopies. ⋯ Laboratory exams showed anaemia; the patient also developed hypotension and tachycardia; a CT scan revealed a splenic laceration with haemoperitoneum. A laparotomic splenectomy was successfully carried out.

Incisional hernia after laparotomy closure continues to be an important postoperative complication. Historically, the best results have been obtained with the open Rives-Stoppa technique. This approach is done by fixing a prosthetic mesh behind the posterior fascia of the rectus muscle. ⋯ The recurrence rate of 5.6% confirms the permanence of the repair. The follow-up was 12 months for 44/53 patients and 6 months for 9/53 patients. The procedure for incisional hernia repair used in our study may be performed safely with low complication and recurrence rates and should be considered for the majority of incisional hernia repairs requiring a mesh prosthesis.
