Laparoscopic transperitoneal repair of lumbar incisional hernias: a combined suture and 'double-mesh' technique

Incisional hernia repair after kidney transplantation in a tertiary high-volume center: outcomes from a 10-year retrospective cohort study

BACKGROUND AND AIM

Incisional hernia (IH) after Kidney Transplantation (KT) is a challenging complication due to both technical reasons and patients' complexity. Data regarding outcomes of hernia repair in KT recipients are uncertain, since the biggest part of previous papers focused on risk factors for incisional hernia occurrence and not on its outcomes. Aim of the study was to focus on risk factors for incisional hernia recurrence after surgical repair in KT recipients.

METHODS

Data regarding all consecutive patients undergoing kidney transplantations from January 2011 until September 2020 in Montpellier University Hospital were retrospectively collected from a single institutional database.

RESULTS

After a median follow-up of 48 months (IQR25-75 31-59), data from 1546 consecutive KT were collected. 83 patients underwent 99 incisional hernia surgeries after KT, with 14 patients that had one recurrence (14.4%) and 2 patients that experienced two recurrences (2.4%). Total recurrence rate was 16.8%. At univariate analysis, the only factor associated with an incisional hernia recurrence was having undergone to at least one previous abdominal surgery other than KT (p value 0.002). Overall morbidity was 15% (n = 15), with most of complications classified as mild (59%). No mortality related to incisional hernia repair occurred.

CONCLUSION

IHs after KT represent an important condition. Its surgical management is challenging due to its anatomical complexity and patient's status. This is the largest sample size in the literature of patients treated for IH after KT and it shows that a previous surgery other than the KT is a risk factor for hernia recurrence after surgical repair, without regarding surgical technique or other comorbidity and therapeutical factors.

[Symptomatic lumbar incisional hernia after open nephrectomy: What are the risk factors?]

OBJECTIVE

Lumbar incisional hernias after open nephrectomy are rare but can lead to aesthetic disorder, discomfort or intestinal obstruction. The aim of the study is to highlight their risk factors.

PATIENTS AND METHODS

The characteristics of patients who suffered from symptomatic and surgically treated lumbar incisionnal hernia after open nephrectomy (study group "GE") were compared to those of patients who underwent open nephrectomy without postoperative incisional hernia (control group "GT") using the Student's t test and Mann-Whitney test (statistical significance P value<0.05). GT patients were randomly selected with a 1/4 ratio (1 lumbar incisionnal hernia vs 4 controls).

RESULTS

From 2004 to 2014, 417 open nephrectomies were performed in one university hospital. Forty-five patients were included: 9 in GE and 36 in GT. There was no statistically significant difference between GT and GE for weight, height, body mass index (BMI), emergency, partial nephrectomy, laterality, rib resection, laparoscopic conversion to open surgery, postoperative complications, smoking, diabetes mellitus, cardiovascular history, obesity and sex, but there was a statistically significant difference for age, operative time, chronic obstructive pulmonary disease (COPD) and severe obesity (BMI>35) with, respectively, P=0.05, P=0.02, P=0.04 and P=0.02.

CONCLUSION

Risk factors for lumbar incisional hernia after open nephrectomy are age, operative time, severe obesity and COPD.

Implementation of the trans-abdominal partial extra-peritoneal (TAPE) technique in laparoscopic lumbar hernia repair

Background

There is still not any standardized operative strategy that is well-accepted all over the world for lumbarhernia. We are here to investigate the feasibility of the trans-abdominal partial extra-peritoneal (TAPE) technique in lumbar hernia repair.

Methods

The TAPE technique was applied to 14 patients with lumbar hernia from May 2009 until January 2014. The surgical technique was described in details and follow-ups were performed for further evaluation.

Results

The mean age of the 14 patients was 68 ± 8 years, with the average BMI 25.5 ± 2.1 kg/m². The etiology study showed that 13 cases after surgical operations and one case after trauma. The average size of the hernia defect was 86.8 ± 46.4 cm², while the mean size of the mesh implanted was 275 ± 61.2 cm². The mean operative time was 59.2 ± 8.2 min. There was no intra-operative visceral injury in this serial of cases. There was no conversion case and all patients accepted the TAPE technique successfully. The VAS was 3.8 ± 1.9 and 2.2 ± 1.6 on POD1 and POD3, respectively. The mean post-operative hospital stay was 4.0 ± 1.3 days. The median follow-up time was 33 months. All patients returned to unrestricted movement within 2 weeks after surgery. During the follow-ups, no complication as bulge, seroma, hematoma, wound infection, abscess in surgical area and chronic pain, nor recurrence was observed.

Conclusions

According to our experience in this series of investigations, the TAPE could be a feasible and easy-to-learn technique which can be applied to most of the lumbar hernia repairs.

Laparoscopic ventral/incisional hernia repair: updated Consensus Development Conference based guidelines [corrected]

BACKGROUND

The Executive board of the Italian Society for Endoscopic Surgery (SICE) promoted an update of the first evidence-based Italian Consensus Conference Guidelines 2010 because a large amount of literature has been published in the last 4 years about the topics examined and new relevant issues.

METHODS

The scientific committee selected the topics to be addressed: indications to surgical treatment including special conditions (obesity, cirrhosis, diastasis recti abdominis, acute presentation); safety and outcome of intraperitoneal meshes (synthetic and biologic); fixing devices (absorbable/non-absorbable); abdominal border and parastomal hernia; intraoperative and perioperative complications; and recurrent ventral/incisional hernia. All the recommendations are the result of a careful and complete literature review examined with autonomous judgment by the entire panel. The process was supervised by experts in methodology and epidemiology from the most qualified Italian institution. Two external reviewers were designed by the EAES and EHS to guarantee the most objective, transparent, and reliable work. The Oxford hierarchy (OCEBM Levels of Evidence Working Group*. "The Oxford 2011 Levels of Evidence") was used by the panel to grade clinical outcomes according to levels of evidence. The recommendations were based on the grading system suggested by the GRADE working group.

RESULTS AND CONCLUSIONS

The availability of recent level 1 evidence (a meta-analysis of 10 RCTs) allowed to recommend that not only laparoscopic repair is an acceptable alternative to the open repair, but also it is advantageous in terms of shorter hospital stay and wound infection rate. This conclusion appears to be extremely relevant in a clinical setting. Indications about specific conditions could also be issued: laparoscopy is recommended for the treatment of recurrent ventral hernias and obese patients, while it is a potential option for compensated cirrhotic and childbearing-age female patients. Many relevant and controversial topics were thoroughly examined by this consensus conference for the first time. Among them are the issue of safety of the intraperitoneal mesh placement, traditionally considered a major drawback of the laparoscopic technique, the role for the biologic meshes, and various aspects of the laparoscopic approach for particular locations of the defect such as the abdominal border or parastomal hernias.

Surgical options in lumbar hernia: laparoscopic versus open repair. A long-term prospective study

OBJECTIVE

To determine the safety and effectiveness of laparoscopic lumbar hernia repair.

DESIGN

Prospective clinical study.

SETTING

Abdominal wall unit, university hospital.

PATIENTS

Between January 1995 and December 2008, data from 55 consecutive patients who had undergone laparoscopic (n = 35) or open (n = 20) lumbar hernia repair.

MAIN OUTCOME MEASURES

The primary endpoint was recurrence; secondary endpoints were patient outcomes (morbidity, pain, and return to normal activity).

RESULTS

Mean operating time (P = .01), hospital stay, return to normal activity, analgesic consumption, and pain at 1 month (P < .001) were significantly less in the laparoscopic group. Complications were similar in the 2 groups (37% vs 40%, respectively; P = .50). Traumatic hernias increased local complications versus incisional lumbar hernias (71.4% vs 29%; P = .007). Consumption of analgesics (6.8 ± 6.5 vs 18.1 ± 9.1; P < .001) and pain during the first month (no pain: 90% vs 54.3%; P = .015) were significantly less with a lightweight versus medium-weight mesh. The risk factors associated with recurrences development were localization (P = .01) and size (P = .008). Recurrence rates were 2.9% in the laparoscopic group and 15% in the open group (P = .13).

CONCLUSIONS

Outcomes did not differ with respect to morbidity and recurrence rate after long-term follow-up; however, this study suggested that laparoscopic approach for lumbar hernia is safe, effective, and more efficient than open repair and can be considered the procedure of choice. Open surgery may be considered the best option in the diffuse hernias with size larger than 15 cm.

Is Muscular Atrophy a Contraindication in Laparoscopic Abdominal Wall Defect Repair? A Prospective Study

Laparoscopic surgery for abdominal wall hernias improves short-term results as compared with open hernia surgery. However, no evidence exists to recommend this approach for pseudohernias, which are abdominal wall defects postsurgery caused by denervation and muscular atrophy. The purpose of this study is to analyze whether the laparoscopic approach benefits patients with a pseudohernia. A prospective nonrandomized, single-center clinical study was conducted of 24 patients operated on for pseudohernia. This study was designed with the basic principle of one unit, one surgeon, one mesh, and two techniques (laparoscopic or open double prosthetic repair). The primary end point was assessment of the abdominal wall according to: 1) abdominal perimeter; 2) computed tomography scan; and 3) degree of satisfaction. The secondary end points were intraoperative parameters and comorbidity. Laparoscopy offered no benefits in patients with pseudohernias. Open surgery offered no significant differences in intra- and postoperative morbidity, but if the initial weakness improved with a decrease in abdominal perimeter and visceral content, then there was more than 90 per cent satisfaction ( P < 0.05). The laparoscopic approach does not improve the bulge caused by abdominal muscle atrophy. The option of a muscular and prosthetic reconstruction provides better clinical and cosmetic results.

Traumatic lumbar hernia repair: a laparoscopic technique for mesh fixation with an iliac crest suture anchor

Traumatic lumbar hernia (TLH) is a rare presentation. Traditionally, these have been repaired via an open approach. Recurrence can be a problem due to the often limited tissue available for mesh fixation at the inferior aspect of the hernia defect. We report the successful use of bone suture anchors placed in the iliac crest during transperitoneal laparoscopy for mesh fixation to repair a recurrent TLH. This technique may be particularly useful after previous failed attempts at open TLH repair.

Laparoscopic repair of incisional hernias located on the abdominal borders: a retrospective critical review

BACKGROUND

The aim of this study was to assess feasibility and results of laparoscopic approach to repair incisional hernias of the abdominal borders, the weakest points of abdominal wall.

METHODS

Since 2002 through 2008 a total of 39 patients with fascial defects of the abdominal borders underwent laparoscopic repair. The defects were suprapubic (n=18), subxiphoidal (n=15), and lateral sided (n=6). The body mass index was >oe=30 Kg/m2 in 19 patients. The parietal defects was measured both externally and from within the peritoneal cavity and 56% of meshes were fixed only by tacks, especially in suprapubic site.

RESULTS

The mean operating time was 161.8+/-25 minutes. There was 1 intraoperative complication, an intestinal injury repaired laparoscopically. Conversion was needed in 1 patient for massive adhesions. Postoperative early surgical complications were 7 (1 seroma). Morbidity in obese and nonobese patients showed no statistically relevant difference (P>0.05). There was no postoperative death. Mean hospital stay was 5.1+/-3 days. The mean follow-up was 37 months and recurrence was observed in 3 cases.

CONCLUSIONS

The onlay laparoscopic approach for repair of incisional hernias of the abdominal borders can warrant good results. Obesity is not a contraindication to laparoscopic repair. Anyway, further experiences are necessary to confirm these results.
