Evaluation of cytologic and biochemical variables in blood, plasma, and peritoneal fluid from calves before and after umbilical herniorrhaphy

Objective-To establish reference intervals for cytologic and biochemical variables in peritoneal fluid, whole blood, and plasma in calves with congenital umbilical hernias (CUHs) before and after herniorrhaphy and to assess whether those variables in calves with CUHs were altered, compared with findings in clinically normal calves.Animals-20 Holstein calves with or without a CUH.Procedures-10 calves with CUHs underwent herniorrhaphy. Blood and peritoneal fluid samples from all 20 calves were collected for cytologic and biochemical analyses on days 0 (before surgery), 1, 3, 5, 7, and 15. Data from the 2 groups were compared.Results-Reference intervals for the variables of interest were established for each group, Before surgery, calves with CUHs had significantly greater plasma total protein concentration and creatine kinase (CK) and aspartate aminotransferase activities and peritoneal fluid specific gravity values, compared with values for calves without CUHs. At various time points after surgery, peritoneal fluid total protein concentration; fibrinogen concentration; nucleated cell, polymorphonuclear cell, and lymphocyte counts; specific gravity; and lactate dehydrogenase, aspartate aminotransferase, and CK activities in calves with CUHs were significantly different from values in calves without CUHs. Some plasma and blood variables leg, total protein concentration, neutrophil count, and CK activity were significantly different between the 2 groups.Conclusions and Clinical Relevance-Values of certain cytologic and biochemical variables in peritoneal fluid, blood, and plasma were different between calves with and without CUHs. Thus, determination of reference intervals for these variables is important for interpreting diagnostic test results in calves with CUHs. (Am J Vet Res 2009;70:423-432)

O uso da prótese na correção das hérnias da parede abdominal é um avanço, mas o seu uso indiscriminado, um abuso

The objective is to alert the surgeon about the indiscriminate use of synthetic prosthesis in the correction of inguinal and incisional hernias. The authors provide a brief history of surgery on hernias and a review of the literature, showing the importance of classifying inguinal hernias to fit the type of surgical correction with the defect found, abstaining from treating all hernias, with the same type of surgical procedure. In our opinion, small indirect inguinal hernias (type 1 and 2 of Gilbert) and hernias in women must not, in general, be treated with prostheses. The synthetic material should be reserved for direct and large indirect hernias. Even so, this attitude, besides determining a higher cost for the procedure, can lead to important complications such as infection, rejection, fistula formation, chronic pain, alterations in spermatogenesis and the possibility of carcinogenesis, according to more recent reports. The physiology and anatomy of the abdominal wall should be considered when dealing with incisional hernia corrections, where the surgeon can choose among many techniques to correct those defects, and in selected cases, utilize synthetic material. We conclude that although the use of biomaterials has constituted a great advance in surgery for abdominal wall hernia corrections because they decrease recurrences, and permit treatment of large abdominal hernias, the indiscriminate prosthesis usage is an abuse, and it can determine many serious complications, certainly avoidable with a well indicated non mesh technique .

O uso do pneumoperitônio progressivo no pré-operatório das hérnias volumosas da parede abdominal

Context - Correction of voluminous hernias and large abdominal wall defects is a big challenge in surgical practice due to technical difficulties and the high incidence of respiratory and cardiovascular complications. Objectives - To present the authors experience with inducing progressive pneumoperitoneum preoperative to surgical treatment of voluminous hernias of the abdominal wall. Methods - Retrospective study of six patients who presented voluminous hernias of the abdominal wall and were operated after installation of a pneumoperitoneum. The procedure was performed by placing a catheter in the abdominal cavity at the level of the left hypochondrium with ambient air insufflation for 10 to 15 days. Results - Four of the six patients were female and two male. Ages ranged from 42 to 62 years. Hernia duration varied from 5 to 40 years. Four patients had incisional, one umbilical, and one inguinal hernias. Mean pneumoperitoneum time was 11.6 days. There were no complications related to pneumoperitoneum installation and maintenance. All hernias were corrected without technical difficulties. The Lichtenstein technique was used to correct the inguinal hernia, peritoneal aponeurotic transposition for one of the incisional hernias, with the rest corrected using polypropylene mesh. One death and one wall infection were observed post operatively. No recurrences were reported until now, in 4 to 36 months of follow-up. Conclusion - Preoperative progressive pneumoperitoneum is a safe and easy executed procedure, which simplifies surgery and reduces post-operative respiratory and cardiovascular complications. It is indicated for patients with hernias that have lost the right of domain in the abdominal cavity.

Intradural lumbar disc herniation: report of five cases with literature review

Introduction: Intradural lumbar disc herniations are uncommon presentations of a relatively frequent pathology, representing less than 1% of all lumbar disc hernias. They show specific features concerning their clinical diagnosis, with a higher incidence of cauda equina syndrome, and their surgical treatment requires a transdural approach. Methods: In this article, we describe five cases of this pathology and review the literature as well as some considerations about the difficulties in the preoperative diagnostic issues and the surgical technique. Conclusion: We concluded that for intradural disc herniations the diagnosis is mainly intraoperative, and the surgical technique has some special aspects. © 2012 Springer-Verlag Berlin Heidelberg.

Correction of rectal sacculation through lateral resection in dogs with perineal hernia ? Technique description

The occurrence of perineal hernias in dogs during routine clinical surgery is frequent. The coexistence of rectal diseases that go undiagnosed or are not correctly treated can cause recurrence and postoperative complications. The objective of this report is to describe a surgical technique for treatment of rectal sacculation through lateral resection in dogs with perineal hernia, whereby restoring the rectal integrity.
