Comparison of Post-Operative Complications Between Sublay and Onlay Mesh Repair in Incisional Hernia

Objective: To compare the post-operative complications between sublay and onlay mesh repair in incisional hernia. Materials & Methods: This randomized controlled trial was conducted at Department of Surgery, Sandeman Provincial Hospital Quetta from May 2019 to November 2019. Total 250 patients with incisional hernias for more than 3 months, having age 20-40 years either male or female were selected. Then selected patients were placed randomly into two groups i.e. Group A (Sublay group) & Group B (Onlay group), by using lottery method. Patients were called for follow up 15th day for post-operative complications in term of wound infection and seroma formation. Results: The mean age of patients in group A was 34.73 ± 4.32 years and in group B was 34.51 ± 4.67 years. Out of these 250 patients, 161 (64.40%) were female and 89 (35.60%) were males with female to male ratio of 1.8:1. Wound infection was seen in 07 (5.60%) patients in group A (Sublay technique) and 17 (13.60%) patients in group B (Onlay technique) with p-value of 0.033. Seroma formation was seen in 09 (7.20%) patients in group A (Sublay technique) and 26 (20.80%) patients in group B (Onlay technique) with p-value of 0.002. Conclusion: This study concluded that rate of wound infection and seroma formation is less after sublay mesh repair for incisional hernia as compared to onlay repair.

Long Term Evaluation of Paraumbilical Hernioplasty by Onlay Technique

Objective: To evaluate long term results of paraumbilical hernioplasty by onlay technique. Material & Methods: This prospective study was started in Jan 2017 and completed in Oct 2021. A total number of 196 patients having paraumbilical hernia were included in the study by convenient sampling. Patients with recurrent, strangulated and obstructed hernia as well as patients with ulcerated skin over the hernia were excluded from the study. All the patients were operated under general anesthesia with muscle relaxants. A non-absorbable standard prolene mesh (15x15 cm or 30x30 cm) was used and fixed with prolene 3-0 suture. Redivac drain was used over the mesh for minimum of three days. After discharge, all the operated cases were advised to visit the outpatient department after one week, one month, three months, six months, one year and two years. Maximum follow-up was two years and minimum was one year to assess the long term complication including recurrence. Demographic data along with diagnosis, complication, were collected and analyzed with Excel 2019. Results: Total 196 patients were operated for paraumbilical hernia. From which 53 were male and 143 were female. Minimum age was 18 years old and oldest patient was 78 years old. Average age was 40.19± 10 years, median age was 38 years. Seroma was seen in 04 patients. Superficial wound infection was observed in 02 patient no deep-seated infection was reported in our study. During three months of follow-up, numbness was noted in 03 patients and 02 patients had pain at the operation site during manual work. After two years recurrence was observed in two female patients, who failed to control their weight. Conclusion: Paraumbilical hernia is very common presentation in female patients. In order to prevent complication of hernia like, incarceration, strangulation and obstruction, early repair of the hernia is recommended in all the cases. Onlay mesh hernioplasty is one of the safest techniques which is relatively easy procedure, has a short learning curve with promising results. It has a low recurrence rate.

Substitution Buccal Mucosal Graft Urethroplasty for Long Segment Anterior Urethral Stricture : Our Experience in Dorsolateral Onlay Approach

Background: Currently the most favorable single stage procedure for management of long segment anterior urethral stricture is dorsal onlay technique of urethroplasty. This required circumferential extensive mobilization of the urethra, which might cause ischemia of urethra in addition to chordee. To evaluate the short term outcome of dorsolateral onlay BMG (Buccal Mucosal Graft) urethroplasty by unilateral urethral mobilization for treatment of long segment anterior urethral stricture Materials and methods: A prospective experimental study from January 2016 to December 2018 is carried out in Department of Urology, Chittagong Medical College Hospital (CMCH) Chattogram, Bangladesh. Total 32 patients of long segment anterior urethral stricture were treated by dorsolateral onlay BMG urethroplasty by unilateral urethral mobilization. Stricture >2cm were included; RGU, MCU and Uroflowmetry were the mainstay of assessment. Success was defined as maximum flow rate >15 ml/s, normal RGU and/ urethroscopy. Failure considered as presence of obstructive symptoms, Qmax < 15 ml/s, stricture on RGU and any post-operative urethral intervention. Results: Mean stricture length was 48.72mm (Range: 30-77mm) and mean follow up time was 22.4months (Range: 12-40 months). Three patients were found to develop stricture at proximal anastomotic site during follow up and required optical internal urethrotomy and considered as failure. 01 patients developed Surgical Site Infection (SSI) which resolved after regular dressing. Success rate was 90.7% Conclusion: Dorsolateral onlay BMG urethroplasty by unilateral mobilization is feasible, safe and easily adoptable for long segment anterior urethral stricture with good short term outcome.

One-stage buccal two-flap urethroplasty using the Kulkarni technique for extended anterior urethral strictures

Introduction. The problem of extended urethral strictures treatment remains relevant due to the complexity of the supervision of such patients and the high frequency of disease recurrence after surgical treatment.Purpose of the study. Evaluation of the effectiveness of one-stage buccal urethroplasty according to the Kulkarni technique using two flaps for extended anterior urethral strictures.Materials and methods. The study included 18 men with an extended anterior urethral stricture, who underwent buccal urethroplasty by perineal access using the Kulkarni dorsolateral onlay technique using two flaps from January 2018 to March 2020, and a postoperative follow-up period of at least 6 months. The study was prospective. Control examination was carried out 3, 6, 12, 18 and 24 months after surgery. The criteria for the recurrence of urethral stricture were the presence of complaints of deterioration in the quality of urination in combination with a decrease in the maximum urinary flow rate of less than 12 ml/sec and the presence of residual urine in an amount of more than 100 ml, as well as the need to perform any surgical intervention to restore the normal passage of urine.Results. The age of the patients ranged from 32 to 72 years (median 58 years). The length of the stricture ranged from 6 to 11 cm (median, 8 cm). The stricture was localized in the penile segment in 11 (61.1%) cases and the penile and bulbar urethra in 7 (38.9%) cases simultaneously. An iatrogenic cause of urethral stricture occurred in 11 (61.1) patients, idiopathic in 5 (27.8%) patients and inflammatory in 2 (11.1%) patients. The stricture was primary in 12 (66.7%) cases and recurrent in 6 (33.3%). Spontaneous urination was preserved in 6 (33.3%) patients, cystostomy existed in 12 (66.7%) patients. The follow-up period after surgery ranged from 3 to 24 months (median - 12 months). Recurrence of urethral stricture was noted in 3 (16.7%) cases. The use of this technique for recurrent forms of the urethral stricture (recurrence after the previous urethroplasty) is the most significant risk factor for treatment failure. 1 (5.6%) case of erectile dysfunction and stress urinary incontinence has taken place of the late postoperative complications.Conclusions. The Kulkarni operation using two buccal flaps for extended strictures of the anterior urethra allows to achieve high rates of efficacy and safety of a treatment, however, the risk of failure increases significantly when used for the treatment of recurrent types of strictures.

Incisional hernia after liver transplantation: mesh-based repair and what else?

Purpose Incisional hernia (IH) is not uncommon after liver transplantation (LT). We investigated the long-term outcome of mesh-based hernia repair using an inlay-onlay technique. Methods Our analysis was based on a prospective collected database of all LT recipients from our hospital over a period of 15 years. We analyzed clinical data including the period between LT and hernia development, the size and localization of the hernia, the length of in-hospital stay, immunosuppression, and postoperative morbidity, as well as follow-up data. The median follow-up period was 120 (range 12–200) months. Results Among a total of 220 patients who underwent a collective 239 LTs, 29 (13%) were found to have an IH after a median period of 27.5 months (range 3–96 months). There were 12 (41%) men and 17 (59%) women, with a median age of 51 years. The median size of the IH was 13 cm (range 2–30 cm) and the median in-hospital stay was 6 days. Mild postoperative complications developed in seven patients, including two onlay mesh infections. One patient (3.4%) suffered recurrence. Conclusion Mesh-based hernia repair using the inlay/onlay technique represents an effective and safe method for patients with an IH after LT, without additional risk from continuous immunosuppression.

Onlay repair using self-gripping mesh for lateral trocar site hernia after laparoscopic incisional hernia repair: A case report with short and mid-term outcomes

IntroductionTrocar site hernia (TSH) is an uncommon complication after laparoscopic surgery, but may potentially require surgical intervention. The available data have shown the importance of prediction and prevention, and the optimal surgical approach for TSH remains unclear and its long-term outcome is scarcely available. Here, we present a case of a lateral TSH after laparoscopic incisional hernia repair, which was successfully repaired using the onlay technique with a self-gripping mesh.Case PresentationA 74-year-old woman presented with an abdominal incisional hernia at the midline after an open cholecystectomy. She underwent laparoscopic surgery for incisional hernia with intraperitoneal onlay mesh repair. Fascial closure was performed for trocar sites. After 12 months, she noticed a painful bulge in the left upper quadrant suggestive of TSH. At the time of diagnosis, her body mass index was 32 kg/m2. TSH repair was performed under general anesthesia. A 3 × 3 cm defect was identified, and the hernial content was found to be the omentum. Defect closure was performed using interrupted sutures followed by placement of a self-gripping mesh (11 × 11 cm in size, obtaining a 4 cm overlap for the defect). The operative time was 80 min. The postoperative course was uneventful except for a spontaneously resolved seroma. CT scan at the 1-year follow-up and physical examination at the 2-year visit showed no recurrence.ConclusionOur proposed onlay repair using self-gripping mesh may be considered as the treatment of choice for cases of lateral TSH after laparoscopic incisional hernia repair.
