Conclusions We do not advocate primary repair for clinically significant hernias, and we believe good techniques are available to allow for the deferred management of select hernias. We also believe mesh infection rates are not common when performed concomitantly with LGB. Synthetic mesh materials should be considered in the repertoire of techniques to repair ventral hernias during gastric bypass surgery.

Editorial comment
Comment on: Management of ventral hernias during laparoscopic gastric bypass As bariatric surgeons, what should we do when we find a previously unsuspected ventral hernia during gastric bypass? Dr. Dallal’s group from the Albert Einstein Medical Center addresses this interesting and practical question with a retrospective review of their operative experience. When we encounter an unsuspected ventral hernia during the performance of gastric bypass, we have 3 surgical options. The simplest option—and the 1 taken by many bariatric surgeons—is to do nothing. The presence of the hernia is merely noted, and its formal repair deferred until several months or more after the bypass. Such an approach follows the dictum of “first do no harm” and offers several potential benefits. First,
the placement of mesh into a clean-contaminated field is avoided. Second, the surgeon does not perform a procedure for which the patient has not given explicit consent. Finally, this approach allows time for the patient to lose weight, making the ultimate hernia repair more technically facile and potentially secure. The downside to this deferral of definitive repair is that it leaves the patient with the potential for incarceration and obstruction, which could in turn lead to the blowout of the proximal or distal anastomosis or 1 of the gastric staple lines. The second option is to hedge one’s bets and repair the hernia primarily, with suture material only. An informal poll of the bariatric surgeons at my institution suggested that this

might be the currently favored approach. As with the first option, this strategy sidesteps the issue of mesh placement in a clean-contaminated field. However, it provides the additional benefit of reducing the risk of an incarcerated or strangulated hernia. The final option is to definitively repair the hernia defect with mesh. This is an appealing option, because it provides for a secure and permanent repair of the defect while minimizing the risk of a postoperative incarceration or strangulation. Additionally, it eliminates the need for a subsequent return to the operating room. However, only limited data are available regarding the safety of mesh placement in a cleancontaminated field. If the mesh were to become infected, it would mandate ⱖ2 return trips to the operating room: first to remove the mesh and a second to formally repair the hernia once the infection had resolved. This concern, although theoretical, is substantial enough that mesh placement concomitant with bypass is certainly not the preferred “Board answer” to the question. In this study, the authors report the results of an algorithmic approach to ventral hernia management that includes all 3 of these options. Asymptomatic hernias containing omentum only were left alone. Symptomatic hernias, or those interfering with the performance of the gastric bypass, were repaired. Hernias ⱕ2 cm in diameter were repaired with suture only, and larger ones were treated with the intraperitoneal placement of coated permanent mesh. This report presents 3 interesting results. First, the authors found that ventral hernias are quite common in the gastric bypass population. Of the 325 patients in this series, 26 had a ventral hernia, for an incidence of 8%, or nearly 1 in 12. Second, the authors report that primary hernia repair with suture—an approach favored by many bariatric surgeons—might be the least appealing of the 3 options. Of the 8 patients who underwent such a repair, 2 (25%) developed a postoperative small bowel obstruction at the ventral hernia repair site. Finally, the authors describe excellent outcomes in the patients treated with permanent mesh repair. This report is an important addition to the small body of published data concerning this serious problem. In 2004, Eid et al. [1] retrospectively reviewed the Pittsburgh experience. As did the Einstein group, they noted an unacceptably high rate of recurrence (22%) with primary repair. Unlike the Einstein group, they found that deferral of definitive repair resulted in a very high rate of small bowel obstruction from incarceration. This led the Pittsburgh group to conclude that “all incarcerated ventral hernias
should be repaired concomitant with [gastric bypass].” However, it should be noted that the Pittsburgh group followed a somewhat different therapeutic algorithm that did not include leaving omentum in situ within the hernia sac to preclude subsequent bowel incarceration. The importance of concomitant ventral hernia repair is supported by a case report by Sukeik et al. [2] in which a 5-cm umbilical hernia was identified during laparoscopic gastric bypass in a 50-year-old man. The omentum within the hernia sac was reduced to facilitate completion of the bypass, and the defect was left open at that time. The patient was readmitted to the hospital 1 day after discharge with a small bowel obstruction from an incarceration at the umbilical site. Although the patient was promptly returned to the operating room for surgical intervention, he aspirated on induction of anesthesia and ultimately died of sepsis 7 days later. The report by Dallal et al. recommends that we leave ventral hernias alone only if the sac is safely plugged with viable omentum. When this is not possible, formal repair with permanent mesh appears to be a safe and effective alternative. Given the small size of their study, we need to interpret its conclusions cautiously. However, it could be ultimately turn out that our current concerns regarding the use of mesh during gastrointestinal surgery are overstated.
