Single-center ventral hernia repair with porcine dermis collagen implant.

INTRODUCTION: This study aims to evaluate the outcomes and utilization of porcine acellular dermal collagen implant (PADCI) during VHR at a large tertiary referral center. METHODS: Records of 5485 patients who underwent VIHR from June 1995 to August 2014 were retrospectively reviewed to identify patients >18 years of age who had VIHR with PADCI reinforcement. Use of multiple mesh reinforcement products, inguinal hernias, and hiatal hernias were exclusion criteria. The primary outcome was hernia recurrence, and secondary outcomes were early complications and surgical site occurrences (SSOs). Uni- and multivariate analyses assessed risk factors for recurrence after PADCI reinforced VIHR. RESULTS: There were 361 patients identified (54.5% female, mean age of 56.7 ± 12.5 years, and mean body mass index (BMI) of 33.0 ± 9.9 kg/m2). Hypertension (49.5%), diabetes (24.3%), and coronary artery disease (14.4%) were the most common comorbidities, as was active smoking (20.7%). Most were classified as American Association of Anesthesiologists (ASA) Class 3 (61.7%). Hernias were distributed across all grades of the ventral hernia working group (VHWG) grading system: grade I 93 (25.7%), grade II 51 (14.1%), grade III 113 (31.3%), and grade IV 6 (1.6%). Most VIHR were performed from an open approach (96.1%), and were frequently combined with concomitant surgical procedures (47.9%). Early postoperative complications (first 30 days) were reported in 39.0%, with 71 being SSO. Of the 19.7% of patients with SSO, there were 31 who required procedural intervention. After a mean follow-up of 71.5 ± 20.5 months, hernia recurrence was documented in 34.9% of patients. Age and male gender were predictors of recurrence on multivariate analysis. CONCLUSION: To the best of our knowledge, this is the largest retrospective single institutional study evaluating PADCI to date. Hernias repaired with PADCI were frequently in patients undergoing concomitant operations. Reinforcement with PADCI may be considered a temporary closure, with a relatively high recurrence rate, especially among patients who are older, male, and undergo multiple explorations in a short perioperative period.

Axillopexy.

The present paper is a presentation of our technique of axillopexy, used after the excision of the axillary lymph nodes in 29 cases of breast cancer patients. We have used this technique after Madden modified radical mastectomy or after quadrantectomy for tumors in the external quadrants of the mammary gland. We have studied and compared with a 30 case control group, the duration of the lymphorrhagia the moment of removing the drains, the presence absence of other local complications. We have also measured the time until the beginning of the oncological postoperative therapy. Every one of the aspects we have studied was improved in the axillopexy group.

[Laparoscopic surgery for small bowel obstruction]. / Abordul laparoscopic al ocluziei intestinului subtire.

At the beginning of the laparoscopic surgery, intestinal obstruction was considered an absolute contraindication for this approach, because of the high risk of injuring the bowel. Today, the increased experience allows to apply this method in certain selected cases of small intestine obstruction. We realised a retrospective study, over a period of 7 and a half years (January 1997 - June 2004), regarding the patients admitted and treated in our department for small intestine obstruction, both by open surgery (88 cases) and by laparoscopic surgery (11 cases). We compared the preoperative characteristics of the two subgroups, highlighting the importance of a careful selection of the cases for the success of the laparoscopic approach. We analysed the postoperative evolution of these patients (return of bowel function, postoperative wound evolution, hospital stay, socioeconomic reintegration), which allowed us to draw the conclusion that some of the patients with obstruction of the small intestine may benefit from the advantages of the mini-invasive surgery.

[Intraabdominal malignant pathology missed at laparoscopic cholecystectomy]. / Patologie maligna abdominala omisa la colecistectomia laparoscopica.

Due to its overwhelming benefits, laparoscopic cholecystectomy represents the "gold standard" for the treatment of symptomatic gallbladder stones. Allowing us to quickly solve an easy to diagnose pathology (by ultrasonography), in some cases it may lead us to mis-diagnose some major intraabdominal pathology, perhaps by a superficial interpretation of our clinical examination and para-clinic investigation data. Studying the archives of our clinic from January 1995 up to December 2003, we found 15 cases of intraabdominal neoplasia diagnosed in the year that followed laparoscopic cholecystectomy: 7 colorectal cancers, 4 pancreatic cancers, 2 gastric carcinomas, one uterine and one adrenocortical malignancies. Among these, 6 cases were in an advanced stage--because of local invasion or distant metastases--without the possibility of radical, curative surgery. Only 4 of the 15 cholecystectomies were performed for acute cholecystitis. The average age was 56.3 years, under the age when such malignancies have the maximum incidence.

[The ocular manifestations in the Melkersson-Rosenthal syndrome]. / Manifestari oculare în sindromul Melkersson-Rosenthal.

The Melkersson-Rosenthal syndrome consists of the following signs: recurrent oedema of the lips and intermittent facial oedema with recidivant aspect; recidivant peripheral facial paresis; scrotal tongue. The cases of a 14-years-old girl is presented. She has two elements of the above signs (recurrent oedema of the lips with facial oedema and scrotal tongue), and additionally ocular affectation: keratitis and bilateral blepharitis. This associations, which has not been found in the literature, is emphasized.
