Laparoscopic assisted percutaneous herniorrhapy in dogs using PIRS technique.

ABSTRACT: BACKGROUND:In the literature, no studies describe the use of laparoscopic techniques for inguinal hernia repair in canine clinical patients. The surgical technique-Percutaneous Internal Ring Suturing (PIRS) presented in this article is the world's first minimally invasive laparoscopic surgical technique for inguinal canal closure in dogs. AIM:The aim of the presented study is to evaluate the possibility of employment of the laparoscopic PIRS technique in clinical practice as well as to technically evaluate its usefulness in the treatment of the inguinal hernia in dogs. The presented study describes the procedure and the results of laparoscopic treatment of 11 inguinal hernias in nine dogs (two bilateral). METHODS:The whole procedure is performed under camera control introduced through one umbilical trocar. The very closure of the inner inguinal ring is done with the injection needle by a small puncture over the inguinal canal with the help of which the suture material is inserted, and the canal of the operated inguinal hernia is closed. Each operated dog underwent a thorough clinical examination before surgery which was combined with ultrasound examination of the inguinal canals before, immediately after and three months after surgery. RESULTS:There was no hernia recurrence in the study period in the operated dogs and all individuals returned to full mobility immediately after recovery from anesthesia. CONCLUSIONS:Due to the low invasiveness and simplicity of performance, the PIRS technique described in the study should be taken into account when choosing a treatment method for non-traumatic inguinal hernia in dogs. At the same time, the possibility of using the described technique in other types of inguinal hernia in dogs requires further research.

Project description:BackgroundPartial adrenalectomy has recently been advocated to preserve unaffected adrenal tissue during resection of pheochromocytoma.ObjectiveTo describe a robot-assisted laparoscopic partial adrenalectomy (RALPA) technique and to report on early functional and oncologic outcomes.Design, setting, and participantsFrom 2007 to 2010, 15 RALPA were performed on 12 consecutive patients with pheochromocytoma. Follow-up data of >1 yr are available on 11 procedures. Median follow-up for the entire cohort was 17.3 mo (range: 6-45).Surgical procedurePositioning and port placement is designed for adequate reach and visualization of the upper retroperitoneum. The plane between the adrenal cortex and pheochromocytoma pseudocapsule is identified visually and with laparoscopic ultrasound. The tumor is dissected away from normal adrenal cortex, preserving normal adrenal tissue.MeasurementsPreoperative, perioperative, pathologic, and functional outcomes data were analyzed.Results and limitationsFourteen of 15 cases were completed robotically. Among 15 procedures, 4 were performed on a solitary adrenal gland. Four cases required resection of multiple tumors (up to six) with two performed in a solitary gland. The mean age of the patients was 30 yr, and the mean body mass index was 27. The mean operative time was 163 min, the median estimated blood loss was 161 ml, and the median tumor size was 2.7 cm (range: 1.3-5.5). There was one conversion to an open procedure in a patient requiring reoperation on a solitary adrenal gland. One patient who underwent RALPA on a solitary adrenal gland required postoperative steroid supplementation at last follow-up. At a median follow-up of 17.3 mo (range: 6-45), there were no recurrences or metastatic events. Study limitations include small sample size and short follow-up.ConclusionsRALPA for the treatment of pheochromocytoma is feasible and safe and provides encouraging functional and oncologic outcomes, even in patients with a solitary adrenal lesion or multiple ipsilateral lesions.

Project description:Sacrocolpopexy has been dubbed the “gold standard” repair for apical pelvic organ prolapse (POP). This study sought to determine a genetic cause for sacrocolpopexy failure by comparing genotypes from 10 women who suffered from early POP reoccurance after sacrocolpopexy surgery, versus 40 randomly selected women with long term success after the same procedure. We objectively defined early overt failure after robotic-assisted laparoscopic sacrocolpopexy as having a pelvic organ prolapse quantification system examination (POP-Q) of stage III or IV occurring in more than one compartment within six months after surgery. All medical records identified during this process were then reviewed by a panel of urogynecology attendings and fellows to select patients who were truly clinical outliers. By this method we identified 10 patients (cases) who experienced early overt surgical failure. We also randomly selected 40 controls from our research database which includes greater than 500 patients who underwent robotic-assisted laparoscopic sacrocolpopexy during the same time period and had been objectively and subjectively assessed for ≥ 12 months with surgical success at ≥ 12 months that did not undergo prolapse re-operation or re-treatment. Demographics and peri-operative details were compared between cases and controls. Exclusion criteria for controls included use of other graft material besides polypropylene mesh, prior surgery for prolapse involving graft material, and conversion to laparotomy. DNA from the 10 cases and 40 controls was isolated from buccal swabs and genotyped on a single nucleotide polymorphism (SNP) array that contains 250,000 markers (NspI 250K SNP array, Affymetrix, Santa Clara, CA). All women in this study identified as Caucasian. All subjects provided written informed consent to study participation and data release. This was a case-control study approved by the Institutional Review Board at the Atlantic Health System in Morristown New Jersey (R11-10-004).
