Holmdahl V, Backman O, Gunnarsson U, Strigård K. The Tensile Strength of Full-Thickness Skin: A Laboratory Study Prior to Its Use as Reinforcement in Parastomal Hernia Repair. Front Surg 2020; 6:69. [PMID: 31921883 PMCID: PMC6915078 DOI: 10.3389/fsurg.2019.00069] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 11/19/2019] [Indexed: 11/29/2022] Open
Abstract
Purpose: Parastomal hernia is a common complication of an enterostoma. Current methods of repair have high recurrence rates and are associated with severe complications. Autologous full-thickness skin as reinforcement may reduce the recurrence and complication rates. This study aims to investigates the tensile strength of full-thickness skin; information that is essential if we are to proceed with clinical trials on humans. Methods: Full-thickness skin samples from 12 donors were tested for tensile strength, as well as the load tolerated by a suture through the skin. Strips of skin were cut out and stretched until breaking point. Sutures were made through skin samples and traction applied until either the tissue or the suture gave way. All done while recording the forces applied using a dynamometer. Identical tests were carried out on commercially available synthetic and biologic graft material for comparison. Results: The full-thickness skin strips had a median tensile strength of 604 N/cm. This tensile strength was significantly higher than that of the compared materials evaluated in this study. In full-thickness skin, the suture, or tissue endured a median force of 67 N before giving way, which was as high as, or higher than similar sutures through the compared materials. Conclusions: The tensile strength of full-thickness skin vastly exceeds the physiological forces affecting the abdominal wall, and sutures through skin endure high loads before giving way. The tensile strength of a full-thickness skin graft and the strength of sutures through this material will not limit its use for reinforcement in parastomal hernia repair.

Laparoscopic modified Sugarbaker parastomal hernia repair with 2-point anchoring and zigzag tacking of Parietex™ Parastomal Mesh technique. Surg Endosc 2016; 30:5628-5634. [PMID: 27129541 DOI: 10.1007/s00464-016-4927-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2015] [Accepted: 04/07/2016] [Indexed: 12/15/2022]
Abstract
BACKGROUND The ideal mesh and mesh fixation technique for laparoscopic Sugarbaker (SB) parastomal hernia repair have not yet been identified. METHODS Sixteen patients with parastomal hernia who underwent laparoscopic modified SB repair (LSB) between June 2012 and October 2015 were retrospectively analyzed. LSB was performed using a developed standardized 2-point anchoring and zigzag tacking of Parietex™ Parastomal Mesh (PCO-PM) technique. RESULTS Out of 16 cases, 14 were primary and 2 recurrent hernias; 13 were para-end colostomy and 3 were para-ileal conduit (PIC) hernias. The median longitudinal and transverse diameters of the hernia orifice were 5 cm (2.5-7 cm) and 4.2 cm (2-6 cm), respectively. Five cases had a concomitant midline incisional hernia, which was simultaneously repaired. In all cases, the mesh was placed without deflection. The median operation time was 193 (75-386) min. Perioperative complications occurred in two cases (13 %) with PIC, one intra-operatively and the other postoperatively. The intra-operative complication was enterotomy close to the ureteroenteric anastomosis of the ileal conduit; it was repaired through a mini-laparotomy. LSB was accomplished without any subsequent postoperative complications. The postoperative complication was ureteral obstruction that required creation of nephrostomy. Mini-laparotomy was necessary in those two cases (13 %) because of intra-operative enterotomy and severe intra-abdominal adhesions. The median postoperative length of stay was 9 (5-14) days. No recurrence was observed with a median follow-up of 14.5 (2-41) months. CONCLUSIONS Our LSB using standardized mesh fixation technique is safe and feasible, and the PCO-PM seems to be the most optimal prosthesis.

Cardiac tamponade as a life-threatening complication in hernia repair. Surgery 2011; 152:133-5. [PMID: 21944871 DOI: 10.1016/j.surg.2011.08.009] [Citation(s) in RCA: 44] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2011] [Accepted: 08/04/2011] [Indexed: 11/22/2022]
Abstract
BACKGROUND The placement of mesh in the repair of all types of hernia has been reported to decrease recurrence rates. There are several well known complications related to mesh repairs, including infection, erosion, seroma, and pain. Lesser reported are cardiac injuries secondary to anchoring of the mesh to the diaphragm. METHODS We report 2 previously unreported, unpublished cases of cardiac tamponade after mesh fixation to the diaphragm and present a review of the literature and search of the US Food and Drug Administration's Manufacturer and User Device Experience (MAUDE) database. RESULTS We reviewed a total of 10 cases of cardiac tamponade in hiatal hernia repair, 6 resulting in patient mortality, 5 cases in ventral hernia repair, 4 being fatal. Ten cases were caused by the helical tacker, 2 by sutures, 1 by the straight stapler, and in 1 case the cause was not identified. CONCLUSION When anchoring mesh to the diaphragm, it is necessary to consider the risk of injury to the heart and cardiac tamponade, especially if the helical tacker is used in this region. Only with appropriate awareness and recognition can this catastrophic complication be avoided.
