As the number of cardiac and interventional radiologic procedures has risen, the frequency with which surgeons are called to treat groin complications has increased. Infectious groin problems that often involve foreign prosthetic material or remnants of percutaneous femoral closure devices are particularly challenging and require control of bleeding, removal of foreign material, wide debridement, and sometimes arterial resection. Management of the consequential limb ischemia in such cases is controversial. The purpose of this study is to review the utility of extra-anatomic common femoral bypass through the obturator foramen (obturator bypass) as a method of treating limb ischemia after arterial groin infection. From July 1992 through June 2001 a total of 12 patients (six male) presented with severe vascular infections of the groin and underwent obturator bypass. Infections occurred as a consequence of an isolated vascular graft infection (nine) or after a percutaneous interventional femoral access procedure (three). Patients presented with systemic sepsis and a draining sinus (six), infected pseudoaneurysm (two), or hemorrhage (four). Treatment included debridement of the groin wound, sartorius muscle flap coverage of the femoral vessels, antibiotics and synthetic (eight polytetrafluoroethylene and four Dacron) obturator bypass via a lower abdominal extraperitoneal incision from an aortobifemoral bypass graft limb to the superficial femoral artery (six), native iliac to femoral artery (three), iliac to popliteal artery (two), and aortobifemoral bypass limb to the popliteal artery (one). Graft patency and limb salvage were assessed by Kaplan-Meier life table analysis. There were two (17%) deaths (multisystem organ failure at postoperative days 9 and 6) and four major complications (25%) requiring reoperation in the first 30 days. Ten patients (83%) survived, healed their groin wounds, and are infection free. With a mean follow-up of 37 months graft patency and limb salvage at 60 months were 80 and 60 per cent, respectively. There were no late graft infections. We conclude that the obturator bypass is an effective and durable means of revascularization in the presence of the septic groin. This procedure belongs in the armamentarium of all surgeons managing these complications.
While elective open abdominal aortic aneurysm (AAA) repair has been shown to be safe in selected octogenarians, very little is known about the role of endovascular AAA exclusion in this high-risk cohort. A retrospective review of our vascular surgical registry from January 1996 to December 2001 revealed 51 octogenarians that underwent infrarenal AAA repair. Since 1999 all octogenarians who presented for AAA repair were evaluated for preferential endovascular stent graft placement. Over the 6-year period, 35 patients underwent standard open repair while 16 patients were found to be anatomic candidates for and were treated with an endovascular stent graft. Hospital and office charts were reviewed to compare the endovascular cohort to the standard open cohort. Factors considered included patient comorbidities, perioperative data, and operative outcomes. Statistical analysis was done using Wilcoxon rank sum test and Fisher exact test. The median age for the entire group was 83 years. There were 11 females in the open group and 1 female in the endovascular group. There were no statistically significant differences in preoperative patient comorbidities between groups. Total mortality for the entire series was 11.8 per cent but this included 5 ruptured AAAs, all of which patients died, and 11 additional AAAs that were symptomatic, of which 1 patient died. Total nonruptured mortality for the entire series was 2.2 per cent (0% for the endo-group and 3.3% for the open group). There were statistically significant differences between the endovascular versus the open groups when comparing aneurysm diameter (5.6 cm vs. 6.2 cm; P = 0.016), estimated blood loss (225 cc vs. 2100 cc; P < 0.001), ICU days (0 vs. 3; P < 0.001), length of hospital stay (2 days vs. 12 days; P < 0.001), and patients with blood transfusions (1 vs. 27; P < 0.001). When comparing postoperative morbidities, 4 of the endovascular patients (25%) and 25 of the open patients (68.6%) had a complication ( P = 0.006). In conclusion, endovascular stent graft treatment of nonruptured infrarenal AAAs in octogenarians led to significantly better outcomes and should probably be considered the preferred treatment whenever anatomically appropriate. Endovascular exclusion of ruptured AAAs may potentially improve future outcomes in this high-risk group.
The advent of laparoscopic cholecystectomy (LC) has complicated management of common bile duct (CBD) stones. While LC is routine, laparoscopic CBD exploration (LCBDE) is not, and an algorithm to manage suspected choledocholithiasis has not been uniformly accepted. We evaluated current management of choledocholithiasis. Patients suspected of having CBD stones over a 2-year period were evaluated, and 42 studies in the literature were reviewed. Thirty-two patients were identified. Fourteen patients (44%) had LC with intraoperative cholangiogram (IOC) with no preoperative studies. IOC revealed CBD stones in nine (64%). Seven had CBD exploration (CBDE) at cholecystectomy, and two had postoperative endoscopic retrograde cholangiopancreatography (ERCP). CBDE was successful in five cases, and ERCP was successful in one. Eighteen patients (56%) underwent preoperative ERCP. Five (28%) had no CBD stones. ERCP removed stones in nine patients, and four had open CBDE after failed ERCP. Current literature supports LC with IOC without any preoperative studies. Laparoscopic CBDE is highly successful but depends on surgeon experience. Removing CBD stones with ERCP is also very successful but is associated with increased cost, hospital stay, and complications. We conclude that LC with IOC should be performed without preoperative ERCP when choledocholithiasis is suspected. If found, stones should be removed laparoscopically if possible.
