Is it safe to perform laparoscopic ventral hernia repair with mesh in elderly patients?

BACKGROUND: Ventral hernia is a common surgical condition occurring most often as a complication following abdominal surgery. Laparoscopic repair of a ventral hernia has been shown to be safe with low rates of complications, shortened length of stay, and low rates of early recurrence as compared to open surgery. Few studies have documented long-term outcomes of laparoscopic repair in elderly patients. The aim of this study is to report the long-term outcomes of laparoscopic ventral hernia repair with mesh in elderly patients. METHODS AND MATERIALS: This is a retrospective study in a university setting with IRB approval. Between the years 2000 and 2006, 117 patients underwent laparoscopic repair of ventral hernia with synthetic mesh. Data were collected using patient charts and radiographic reports. Patient variables included age, sex, size and content of hernia, size of mesh used, length of hospital stay (LHS), estimated blood loss (EBL), follow-up duration, and post-operative complications (PC) including infection, deep vein thrombosis, bleeding, and pulmonary embolism. The comparison was done between two different age groups (A <55 years old; B >or= 55 years old). RESULTS: Current median (range) follow-up periods for group A (<55 years) and B (>or=55 years) were 57.5 and 53 months, respectively. Group A (63 patients) and B (54 patients) had same median LHS (1 day) and size of mesh utilized (285 cm(2)). For groups A and B, the percent female, and the percentages of recurrence, minimal EBL (<50 ml), and PC were 61.9 and 44.4; 1.6 and 3.7; 96.8 and 92.6; 4.8 and 12.9, respectively. Median hernia sizes for groups A and B were 55.1 and 54 cm(2). No significant differences were found for any of the above variables. CONCLUSION: No significant difference was found in outcomes between younger versus older patients undergoing laparoscopic ventral hernia repair with mesh. Laparoscopic repair provides a durable and effective method of repairing a ventral hernia with low morbidity and mortality in the elderly population.

Comparison of conventional laparoscopic and hand-assisted oncologic segmental colonic resection.

BACKGROUND: Laparoscopically assisted colon resection has evolved to be a viable option for the treatment of colorectal cancer. This study evaluates the efficacy of hand-assisted laparoscopic surgery (HALS) as compared with totally laparoscopic surgery (LAP) for segmental oncologic colon resection with regard to lymph node harvest, operative times, intraoperative blood loss, pedicle length, incision length, and length of hospital stay in an attempt to help delineate the role of each in the treatment of colorectal cancer. METHODS: Patient charts were retrospectively reviewed to acquire data for this evaluation. Between June 2001 and July 2005, 40 patients underwent elective oncologic segmental colon resection (22 HALS and 18 LAP). The main outcome measures included lymph node harvest, operative times, intraoperative blood loss, pedicle length, incision length, and length of hospital stay. RESULTS: The two groups were comparable in terms of demographics. The tumor margins were clear in all the patients. The HALS resection resulted in a significantly higher lymph node yield than the LAP resection (HALS: 16 nodes; range, 5-35 nodes vs LAP: 8 nodes; range, 5-22 nodes; p < 0.05) and significantly shorter operative times (HALS: 120 min; range, 78-181 min vs LAP: 156 min; range, 74-300 min; p < 0.05). Both groups were comparable with regard to length of hospital stay, pedicle length, and intraoperative blood loss. However, the LAP group yielded a significantly smaller incision for specimen extraction (LAP: 7 cm; range, 6-8 cm vs HALS: 5.5 cm; range, 5-7 cm; p < 0.05). CONCLUSION: The findings suggest that hand-assisted laparoscopic oncologic segmental colonic resection is associated with shorter operative times, more lymph nodes harvested, and equivalent hospital stays, pedicle lengths, and intraoperative blood losses as compared with the totally laparoscopic approach. The totally laparoscopic technique was completed with a smaller incision. However, this less than 1 cm reduction in incision length has doubtful clinical significance.

Bilateral laparoscopic inguinal hernia repair in patients with occult contralateral inguinal defects.

BACKGROUND: A high incidence of bilateral inguinal defects found on laparoscopic evaluation during hernia repair has been reported. However, expectation of bilateral inguinal defects in patients who are diagnosed with pure unilateral hernia might be underestimated. A prospective clinical study was performed to reveal a rate of contralateral occult defects in patients who were diagnosed with unilateral inguinal hernia prior to primary laparoscopic totally extraperitoneal (TEP) repair. METHODS: One hundred consecutive male patients with primary unilateral inguinal hernias were included in the study. Patients with known bilateral inguinal hernias as well as femoral, giant and combined hernias were excluded. All patients underwent TEP with exploration and evaluation of the contralateral groin. RESULTS: Median follow-up was 24 (4-46) months. Median age was 48 (18-73). Mean operative time was 42.2 (18-167) min. There were 78 (78%) patients with pure unilateral hernias and 22 (22%) patients with bilateral hernias whose contralateral inguinal defect or hernia was revealed only intraoperatively. Of those, 19 (86%) had right and 3 (14%) left occult defects. Minor complications occurred in 17 (17%) patients. There were no major complications. Two patients required a 23-hour stay in the hospital for urinary retention and hypoxia. Median period of returning to normal activity was 7 (5-14) days. There were two (2%) recurrences. Median period of returning to normal activity was 6.2 days after unilateral repair and 8.4 days after bilateral TEP. CONCLUSION: This study revealed 22% occurrence of bilateral inguinal defects in the patients who are diagnosed with pure inguinal hernia before surgery, with higher incidence for those with left inguinal hernia. It appears that routine contralateral groin exploration and evaluation during TEP is valuable. Patients with occult bilateral hernias are benefit from bilateral TEP.
