LAPAROSCOPIC VS. OPEN VENTRAL HERNIA REPAIR

Types of Incisional Hernia repair:

Primary closure only

Primary closure with relaxing incisions

Primary closure with mesh reinforcementOnlay mesh placement only

Inlay mesh placementRetrorectus mesh placement

Intraperitoneal mesh placement

Advantages of open:

Can be done in virtually all patients Minimizes the chance of unrecognized bowel injury

Advantages of Laparoscopic:

Allows the surgeon to thoroughly dissect adhesions around the hernia Inspect for occult adjacent defects Place the mesh over a larger space thereby minimizing the chances of recurrence.

EVIDENCE:

In 2 prospective studies, the group that was operated on laparoscopically had a lower rateof postoperative and longer-term complications, surgery time was significantly lower,

and hospitalization was shorter than with an open approach (1,2)

In one retrospective study there was lower rate of perioperative complications, shorterhospital stay and lower rate of recurrence in patients who underwent laparoscopic surgery

as compared to open approach(3)

In a meta-analysis of 8 studies three major outcomes compared were perioperativecomplications, operative time and length of hospital stay (4).

All outcomes were significantly better for the laparoscopic approach.REF #1 Surg Endosc 1999 Mar;13(3):250-2.

Total of 60 patients were assigned at random over a 3-year period Half of them were operated upon laparoscopically and the rest with open surgery.

RESULTS:

Groups were homogeneous in terms of demographic and clinical characteristics1. Laparoscopic group had lower rate of postoperative and longer-term

complications2. Surgery time was significantly lower (p < 0.05)3. Hospitalization time was also significantly lower (p < 0.05).

CONCLUSIONS: Laparoscopic treatment of postoperative eventration and primaryventral hernia reduces complications and relapse rates, eliminates reintervention throughmesh infection, reduces operative time, and considerably shortens the hospital stay.

Prospective study comparing early outcomes after laparoscopic and open ventral herniarepairs.

n = 257 approx 2 years To increase the homogeneity of the sample, umbilical hernia repairs, parastomal herniarepairs, nonelective procedures, procedures not involving mesh, and repairs performed

concurrently with another surgical procedure were excluded.

Postoperative complications (in-hospital or within 30-days) were assessed prospectively RESULTS

o Of the 136 ventral hernia repairs that met the study criteria, 65 (48%) werelaparoscopic repairs (including 3 conversions to open surgery) and 71 (52%) were

open repairs. The patients in the laparoscopic group were more likely to have

undergone a prior (failed) ventral hernia repair (40% vs 27%; p = 0.14), but otherpatient characteristics were similar between the two groups.

1. Overall, fewer complications were experienced by patients undergoinglaparoscopic repair (8% vs 21%; p = 0.03). The higher complication rate in theopen ventral hernia repair group came from wound infections (8%) and

postoperative ileus (4%), neither of which was observed in the patients who

underwent laparoscopic repair.2. The laparoscopic group had longer operating room times (2.2 vs 1.7 h; p = 0.001),

and there was a nonsignificant trend toward shorter hospital stays with

laparoscopic repair (1.1 vs 1.5 days; p = 0.10).

CONCLUSIONS: The patients undergoing laparoscopic repair had fewer postoperativecomplications than those receiving open repair. Wound infections and postoperative ileusaccounted for the higher complication rates in the open ventral hernia repair group.

Otherwise, these groups were very similar. Long-term studies assessing hernia recurrence

rates will be required to help determine the optimal approach to ventral hernia repair.

REF #3 Am Surg 1999 Sep;65(9):827-31; discussion 831-2.

Retrospectively review over a 3-year period 174 open and 79 laparoscopic Similar demographics. The hernias in the open group averaged 34.1 cm2 in size, and mesh used averaged 47.3

cm2.

In the laparoscopic group, the hernia defect averaged 73.0 cm2, and the mesh sizeaveraged 287.4 cm

2.

1. Operative time was longer in the open group, 82.0 versus 58.0 minutes.2. In the open group, there were 38 (21.8%) minor and 8 (4.6%) major complications,

compared with 13 (16.5%) minor and 2 (2.5%) major complications in thelaparoscopic group

3. Hospital stay was shorter for the laparoscopic group, 1.7 versus 2.8 days.4. At an average follow-up of 21 months (range, 2-40 months), there have been 36

recurrences in the open group (20.7%) compared with 2 recurrences in the

laparoscopic group (2.5%).

CONCLUSION: In this series, laparoscopic ventral herniorrhaphy compares favorably toopen ventral herniorrhaphy with respect to wound complications, hospital stay, operative

time, and recurrence rate.

REF #4 Arch Surg. 2002 Oct;137(10):1161-5

Meta-analysis of studies comparing open and laparoscopic ventral (including incisional)hernia repair. HYPOTHESIS: Laparoscopic ventral hernia repair results in better short-term outcomes

than open ventral hernia repair.

3 main outcome measures were perioperative complications, operative time, and lengthof hospital stay.

Across 8 studies, 390 patients underwent open repair and 322 underwent laparoscopicrepair.

1. Perioperative complications were less than half as likely to occur in patientsundergoing laparoscopic repair (14% vs 27%; P =.03; odds ratio, 0.42; 95%

confidence interval, 0.29-0.68).

2. Average length of stay was shorter in the laparoscopic group (2.0 vs 4.0 days; P=.02).3. No statistically significant difference in operative times was noted between

laparoscopic and open repair (99 vs 96 minutes; P =.38).

CONCLUSIONS: Laparoscopic ventral hernia repair offers lower complication rates andshorter length of stay than open repair. However, randomized controlled trials and studieswith long-term follow-up are needed to confirm these findings and to assess long-term

rates of hernia recurrence.

Component Separation:

This method uses bilateral, innervated, bipedicle, rectus abdominis-transversusabdominis-internal oblique muscle flap complexes transposed medially to reconstruct the

central abdominal wall.

The plane of separation is the interface between the external and internal obliquemuscles(5)
