Laparoendoscopic Single-Site Herniorrhaphy After Gynecologic Surgery

Background and Objectives:

Increased interest in laparoendoscopic single-site surgery has instigated research into trials of novel techniques. The procedure we propose may potentially improve patient satisfaction and cosmetic results while diminishing the incidence of trocar-site herniation. We report our initial experience with laparoendoscopic single-site totally extraperitoneal herniorrhaphy for postoperative incisional hernia to determine the procedure''s feasibility and safety.

Methods:

Three patients with incisional hernias after gynecologic surgery underwent laparoendoscopic single-site totally extraperitoneal procedures. We evaluated the patients'' preoperative and postoperative condition, as well as the details of their original surgery. We performed the procedure through a 2-cm umbilical incision followed by mesh insertion and transabdominal suture placement in all patients.

Results:

Laparoendoscopic single-site totally extraperitoneal herniorrhaphy was completed in 80 to 120 minutes. No intraoperative complications were encountered, and surgical blood loss was minimal. The duration of hospital stay ranged from 2 to 4 days. One patient had a postoperative wound infection. The patients have shown no sign of recurrence at 9 months'' follow-up.

Conclusion:

Laparoendoscopic single-site totally extraperitoneal herniorrhaphy appears to be feasible and safe. It may be performed with readily available instruments, although further experience and practice are warranted for a more efficient repair. The procedure has similar advantages to a multiport laparoscopic totally extraperitoneal procedure but yields better cosmetic results. More studies are needed to assess the long-term benefits and complications of this procedure.     

Development of a Measurement System for Laparoendoscopic Single-Site Surgery: Reliability and Repeatability of Digital Image Correlation for Measurement of Surface Deformations in SILS Port

Objective:

Analysis of mechanical measurements in laparoendoscopic single-site surgery (LESS) is important for instrument design and surgical simulators. The aim of this study was to develop a measuring system for different instruments and manipulations in LESS using a single-incision laparoscopic surgery (SILS) port.

Methods:

The loads on the SILS port were applied and recorded by the universal material testing machine by the following method. The handle of the forceps inserted in the SILS port was connected with the machine by a fishing wire and pulled at a constant rate. The surface deformations (displacements and strains) of the SILS port were recorded with digital image correlation (DIC) simultaneously. The correlation between deformation measurements and loads were analyzed. This experiment was repeated 8 times.

Results:

Strong correlations existed between deformation measurements calculated by DIC and objective criteria “loads” applied and recorded by the universal material testing machine (r > 0.98). The correlation coefficients were statistically significant (P < .001). A high repeatability of the results appeared in all repetitions of the experiment.

Conclusions:

A DIC measurement system has been developed for LESS, and comprehensive mechanical parameters of a SILS port can be obtained precisely by using this system. It is reliable and repeatable for evaluation of instruments and manipulations in LESS.     

Safety and Efficacy of Laparoendoscopic Single-Site Surgery for Abdominal Wall Hernias

Background:

Laparoendoscopic single-site surgery has rapidly progressed from the animal laboratory to clinical use since mass production of multichannel ports began in 2007. Indeed, it has now been shown to be feasible and safe for many commonly performed operations.

Methods:

This study cohort comprised 22 unselected patients with abdominal wall hernias of varying types: multiply recurrent inguinal (n=2), suprapubic (n=1), ventral/incisional (n=17), and parastomal hernias (n=2), who underwent laparoendoscopic single-site ventral hernia repair between December 2009 and February 2011. Standard dissecting instruments and a 52cm/5.5mm/30^°angle laparoscope were used.

Results:

Patients included 14 men and 8 women, with a median age of 56 (range, 32 to 78) years and a mean body mass index of 31.5±4.7kg/m². The mean mesh size was 460cm² (range, 225 to 884cm²). Mean operation time was 125 minutes for ventral/incisional hernias and 270 minutes for parastomal hernias. No conversions to multiport or open surgeries were necessary. There was no mortality or morbidity, and no recurrence at 6- to 18-month follow-up. The mean satisfaction score was 2.7 (range, 2 to 3) with no patients reporting dissatisfaction with the procedure.

Conclusion:

This series, though relatively small, represents a diverse group of patients with varying abdominal wall hernias, including parastomal hernias. These successful laparoendoscopic single-site surgeries, with no complications, demonstrate safety and efficacy, albeit in a specialized hernia center. This study is a prelude to the eventual validation of laparoendoscopic single-site hernia surgery with prospective randomized controlled trials.     

Transumbilical Retrieval of Surgical Specimens Through a Multichannel Port

Background:

Laparoscopic surgery is often used to excise adnexal masses; however, the retrieval of specimens such as large cystic masses through conventional 5- or 10-mm ports is difficult and time-consuming. We compared outcomes between conventional laparoscopic surgery for adnexal masses and transumbilical specimen retrieval through a multichannel port during single- or 2-port laparoscopy.

Methods:

A total of 341 patients who underwent laparoscopic surgery for adnexal masses from November 2006 to December 2010 were included. The patients were divided into 2 groups: group I consisted of 249 patients who underwent conventional laparoscopy, and group II consisted of 92 patients who underwent single- or 2-port laparoscopy using a multichannel port. The clinical characteristics and operative outcomes of the 2 groups were compared.

Results:

The mean operation time was 51.8 ± 21.5 minutes in group I and 57.2 ± 23.9 minutes in group II. The mean specimen retrieval time was longer in group I (2.9 ± 4.0 minutes) than in group II (2.2 ± 1.8 minutes). Endoscopic bag rupture during specimen retrieval occurred in 11 patients in group I and in no patients in group II.

Conclusions:

The transumbilical retrieval of surgical specimens through a multichannel port with a wound retractor was safe and did not result in leakage of the cystic contents. This technique reduced the specimen retrieval time, especially for large masses. However, the mean operation time was not shortened with this procedure, because of the learning period and the time required to prepare the umbilical multichannel port.     

Laparoscopy and natural orifice surgery: first entry safety surveillance step

Background and Objective:

We are sharing information regarding the surveillance of the first entrance port in laparoscopic and natural orifice transvaginal endoscopy surgeries. However, we are not analyzing techniques or other surgical findings.

Method:

In this study, 160 women with previous abdominal pelvic surgeries underwent laparoscopic surgery, 145 patients underwent transvaginal Minilaparoscopy Assisted Natural Orifice Surgery (hybrid), and 3 patients underwent pure natural orifice transvaginal endoscopic surgery (pure). For those patients who had laparoscopy and hybrid procedures, the surveillance was from a laparoscope or gastroscope placed in a secondary port. Surveillance in pure cases was done using a gastroscopic retro view to see the pouch of Douglas.

Results:

The laparoscopic procedures were gynecological procedures. The hybrid procedures included gynecological procedures as well as appendectomies and cholecystectomies; the pure procedures were cholecystectomies. There were a few minor vascular and bowel injuries in the laparoscopy group. There were no injuries in the transvaginal hybrid or pure procedures groups.

Conclusion:

The surveillance of the first entrance port can be an effective precautionary step. The cumulative experience suggests that using such surveillance in cases involving patients with prior surgery may assist in recognizing complications that might otherwise be missed.     

Single-Site Laparoscopic Surgery for Inflammatory Bowel Disease

Background and Objectives:

Single-site laparoscopic colorectal surgery has been firmly established; however, few reports addressing this technique in the inflammatory bowel disease population exist.

Methods:

We conducted a case-matched retrospective review of 20 patients who underwent single-site laparoscopic procedures for inflammatory bowel disease compared with 20 matched patients undergoing multiport laparoscopic procedures. Data regarding these patients were tabulated in the following categories: demographic characteristics, operative parameters, and perioperative outcomes.

Results:

A wide range of cases were completed: 9 ileocolic resections, 7 cases of proctocolectomy with end ileostomy or ileal pouch anal anastomosis, 2 cases of proctectomy with ileal pouch anal anastomosis, and 2 total abdominal colectomies with end ileostomy were all matched to equivalent multiport laparoscopic cases. No single-incision cases were converted to multiport laparoscopy, and 2 single-incision cases (10%) were converted to an open approach. For single-incision cases, the mean length of stay was 7.7 days, the mean time to oral intake was 3.3 days, and the mean period of intravenous analgesic use was 5.0 days. There were no statistically significant differences between single-site and multiport cases.

Conclusions:

Single-site laparoscopic surgery is technically feasible in inflammatory bowel disease. The length of stay and period of intravenous analgesic use (in days) appear to be higher than those in comparable series examining outcomes of single-site laparoscopic colorectal surgery, and the outcomes are comparable with those of multiport laparoscopy. This may be because of the nature of inflammatory bowel disease, limiting the benefits of a single-site approach in this population.     

Small Bowel Injury During Laparoendoscopic Single-Site Surgery for Simple Nephrectomy

Background and Objectives:

A 71-year-old man underwent a right simple nephrectomy via the laparoendoscopic single-site surgery (LESS) approach for intractable right flank pain and gross hematuria. A postoperative diagnosis of duodenal injury was suspected by physical findings and confirmed by computed tomography imaging.

Methods:

Emergency exploratory laparotomy revealed a <5-mm full-thickness perforation of the duodenum and an accompanying 1-cm seromuscular injury.

Results:

The subsequent postoperative course was unremarkable except for a right intraabdominal seroma that resolved without intervention.

Conclusion:

LESS nephrectomy is an effective surgical approach, but more data are needed regarding its surgical outcomes and complications. This case shows that the LESS approach is not without the risk of life-threatening complications, and it must be performed by experienced surgeons in select patients who are notably interested in improved cosmesis, after an informed consent that includes the potential for complications.     

Laparoendoscopic single-site (LESS) pyeloplasty for horseshoe ureteropelvic junction obstruction

Background and Objective:

Pyeloplasty in horseshoe kidneys can be challenging due to aberrant vasculature, renal malrotation, and ectopic location. Fewer than 20 cases of minimally invasive (MIS) pyeloplasty in horseshoe kidneys have been reported in the literature to date. We herein report the first 2 cases of laparoendoscopic single-site (LESS) pyeloplasty for UPJ obstruction in horseshoe kidneys.

Methods:

Two patients with symptomatic ureteropelvic junction obstruction in horseshoe kidneys were treated with an Anderson-Hynes LESS pyeloplasty. This was performed using three 5-mm trocars through a single umbilical incision, plus an accessory 3-mm port at the anterior axillary line to facilitate suturing and subsequent drain placement.

Results:

Both patients had BMI <23. The operative times were 204 minutes and 171 minutes. Blood loss was negligible, and no intraoperative complications occurred. To date, 9-month renography for patient 1 demonstrates stable renal function and unobstructed drainage. After stent removal, patient 2 was asymptomatic.

Conclusion:

In experienced hands, LESS reconstructive techniques are applicable to complex renal anomalies. LESS pyeloplasty for UPJ obstruction associated with horseshoe kidneys is feasible, safe, and effective in select patients.     

Perioperative comparison of robotic assisted laparoendoscopic single-site (LESS) pyeloplasty versus conventional LESS pyeloplasty

Background

Conventional laparoendoscopic single-site (C-LESS) pyeloplasty is technically challenging due to instrument clashing, loss of triangulation, and difficulty sewing. Application of the da Vinci S or Si robotic platforms could potentially overcome these challenges.

Objective

Compare our initial experience with robotic assisted laparoendoscopic single-site (R-LESS) pyeloplasty to our latter experience with C-LESS pyeloplasty (ie, after the initial 15 patients).

Design, setting, and participants

This single-institution retrospective observational cohort study involved consecutive patients who presented with symptomatic ureteropelvic junction obstruction and who were deemed suitable for single-incision pyeloplasty by the treating surgeon.

Measurements

Demographic, clinical, perioperative, and early postoperative comparative outcomes.

Results and limitations

Ten patients each underwent R-LESS or C-LESS pyeloplasty by a single surgeon between March 2009 and July 2011. For R-LESS and C-LESS groups, age, gender distribution, body mass index, proportion of patients with prior abdominal surgery, estimated blood loss, and hospital length of stay were statistically similar. Mean operative time was significantly longer for R-LESS (226 vs 188 min; p = 0.007). C-LESS pyeloplasty alone required an accessory port for the anastomosis in 10 of 10 cases. Two conversions to standard laparoscopy and two postoperative complications occurred in 3 of 10 patients in the C-LESS group, compared with no conversions and one postoperative complication in the R-LESS group (p = 0.26). Study limitations are a retrospective design, a modest number of patients, and a lack of quantification of subjective outcomes such as instrument clashing and maneuverability.

Conclusions

Adaptation of the da Vinci Si robotic surgical platform to laparoendoscopic single-site pyeloplasty appears to reduce the physical learning curve for this complex procedure. Future prospective, comprehensive evaluation of additional outcomes including subjective parameters, cosmesis, and longer term functional outcomes will help better define its role in minimally invasive dismembered pyeloplasty and better estimate its associated learning curve.     

Laparoscopic Appendectomy in Women Without Identifiable Pathology Undergoing Laparoscopy for Chronic Pelvic Pain

Objectives:

To assess the effectiveness of appendectomy in women undergoing laparoscopy for chronic pelvic pain without identifiable pathology.

Methods:

This retrospective cohort study included women aged 15 to 50 years who underwent laparoscopic surgery for chronic pelvic pain without identifiable pathology. The cohort was divided into 2 groups: women who underwent appendectomy and women who had not undergone appendectomy at laparoscopic surgery. Postoperative pain was assessed at 6-week follow-up and by subsequent mailed questionnaire.

Results:

Women who underwent appendectomy (n = 19) were significantly more likely to report improvement in pain at 6-week follow-up than women who did not undergo appendectomy (n = 76) (93% vs 16%; P < .001). Thirty-six patients (38%) responded to the questionnaire at a median of 4.2 years after surgery, when the median change (improvement) in reported pain was greater in the appendectomy group than in the nonappendectomy group.

Conclusion:

Appendectomy is effective therapy for patients with chronic pelvic pain of unknown etiology who are undergoing laparoscopy.     

Single-port surgery: laboratory experience with the daVinci single-site platform

Background and Objectives:

The purpose of this study was to evaluate the feasibility and validity of a dedicated da Vinci single-port platform in the porcine model in the performance of gynecologic surgery.

Methods:

This pilot study was conducted in 4 female pigs. All pigs had a general anesthetic and were placed in the supine and flank position. A 2-cm umbilical incision was made, through which a robotic single-port device was placed and pneumoperitoneum obtained. A data set was collected for each procedure and included port placement time, docking time, operative time, blood loss, and complications. Operative times were compared between cases and procedures by use of the Student t test.

Results:

A total of 28 surgical procedures (8 oophorectomies, 4 hysterectomies, 8 pelvic lymph node dissections, 4 aorto-caval nodal dissections, 2 bladder repairs, 1 uterine horn anastomosis, and 1 radical cystectomy) were performed. There was no statistically significant difference in operating times for symmetrical procedures among animals (P=0.3215).

Conclusions:

This animal study demonstrates that single-port robotic surgery using a dedicated single-site platform allows performing technically challenging procedures within acceptable operative times and without complications or insertion of additional trocars.     

Safety of Culdotomy as a Surgical Approach: Implications for Natural Orifice Transluminal Endoscopic Surgery

Objective:

To evaluate the efficacy and safety of culdotomy as a surgical approach to access the peritoneal cavity and discuss its implications for natural orifice transluminal endoscopic surgery (NOTES).

Methods:

A retrospective chart review of women undergoing culdotomy for tubal sterilization (N=219) between January 1995 and December 2005 was performed. The Accordion Grading System was used for the severity of complications.

Results:

No intraoperative complications were noted. Postoperative complications occurred in 7 patients (3.2%): 6 infections (grade 2) and 1 case of hemorrhage (grade 3). Conversion to laparoscopy was necessary in 10 patients (2.2%) due to anatomical constraints or pelvic adhesions; however, culdotomy with entry into the abdominal cavity was nevertheless successful in all 10 cases. The difference in the proportion with a history of pelvic surgery between the conversion and nonconversion groups was not statistically significant (P = .068). Patients with BMI ≥30 had a higher conversion rate compared to patients with BMI <30 (11.4% versus 1.5%, P = .011). Tubal sterilization via culdotomy was successfully performed in all 11 women with no prior vaginal deliveries.

Conclusion:

Culdotomy appears to be a safe surgical approach to access the peritoneal cavity and is associated with a low complication rate. These data support the feasibility and safety of utilizing the cul-de-sac as an access portal for natural orifice transluminal endoscopic surgery.     

Secured Independent Tools in Peritoneoscopy

Background and Objectives:

Secured independent tools are being introduced to aid in peritoneoscopy. We present a simple technique for anchoring instruments, powered lights, and micro machines through the abdominal wall.

Methods:

We used a laparoscopic trainer, micro alligator clips with one or two 2-0 nylon tails and cables for engines and lights. The above instruments were introduced via a 12-mm or 15-mm port. Clips were placed for traction, retraction and exposure, lights for illumination, and motors for potential work. A laparoscopy port closure or suture passer was introduced percutaneously to grab and extract the tails or cables outside of the simulated abdominal cavity. The engines and lights were powered by a direct electric current (DC) plugged into exteriorized cables.

Results:

We used 2 to 3 clips for each, and engines performed well.

Conclusion:

This basic simulation adds independent instruments, lights, and engines. We replaced cannulas with threads or cables in an attempt to limit the number of ports. This technique further opens the door for innovations in wired machines in laparoscopy, single-port laparoscopy, or natural orifice surgery.     

A simple, effective technique for port-site closure after laparoscopy

Background and Objectives:

Fascial closure of port sites represents a challenging issue in laparoscopic surgery. The aim of this article is to introduce a procedure that allows the safe suturing of the abdominal fascia in these wounds.

Methods:

We herein describe a simple technique for fascial closure after laparoscopy using a transcutaneous approach and standard surgical instruments for suture.

Results:

The method was used in 34 patients with no intraoperative incidents and no port-site hernias during a mean follow-up of 23.9 months (median 20.5, range 5 to 47).

Conclusion:

The procedure is easy to perform, safe, fast, and inexpensive.     

Surgical Management of Adnexal Masses in Pregnancy

Background and Objectives:

Our objective was to review the surgical management, surgical outcomes, and obstetric outcomes of adnexal masses in pregnancy.

Methods:

A retrospective review was performed of pregnant women before 20 weeks of gestation who underwent laparoscopy or laparotomy for management of an adnexal mass during the period of January 2005 to June 2012 at a university-affiliated hospital.

Results:

Thirty-five pregnant women underwent surgical removal of adnexal masses during the 7.5-year study period: 21 (60.0%) underwent laparoscopic surgery, and 14 (40.0%) underwent laparotomy. The left upper quadrant entry technique was used in 20 women. Conversion to laparotomy was required in 2 women because of extensive pelvic adhesions. The mean gestational age at surgery was 15.2 ± 1.9 weeks. All women had undergone ovarian cystectomy. A malignant mass was found in 3 (8.6%) women. The laparoscopy group had a significantly less blood loss (67.4 ± 55.8 vs 153.6 ± 181.0 mL, P = .048) and shorter mean hospital stay (2.8 ± 1.0 vs 3.8 ± 1.1 days, P = .006) than the laparotomy group. One woman miscarried soon after surgery. There was no significant difference in obstetric outcomes between the laparoscopy and laparotomy groups.

Conclusion:

Surgical management of adnexal masses during pregnancy appears to have favorable outcomes for the mother and the fetus.     

Single-Site Robotic Cholecystectomy at an Inner-City Academic Center

Introduction:

We investigate the safety and efficacy of single-site robotic cholecystectomy compared to laparoscopic cholecystectomy at an inner-city academic medical center.

Materials and Methods:

Retrospective analysis comparing single-site robotic to laparoscopic cholecystectomies from August 1, 2013, to January 31, 2015, was conducted. Age, gender, race, body mass index (BMI), total operative time (docking and console time for robotic cases), length of stay, comorbidities, and conversion to open procedures were examined. The χ² and Student''s t test were used for categorical and continuous data, respectively. A P ≤ 0.05 was considered statistically significant.

Results:

From August 2013 to January 2015, 70 single-site robotic cholecystectomies and 70 laparoscopic cholecystectomies were performed. Patients were older (mean age, 40.3 years vs 47.6 years; P = .0084), had a higher mean BMI (29.5 vs 32.4 kg/m²; P = .011), and had a higher assigned ASA (American Society of Anesthesiologists) classification (P = .024) in the laparoscopic than in the single-site group. Hypertension was more common in the laparoscopic group (P = .0078). Average docking time was 11.5 (SD 5.7) minutes, and the average console time was 52.8 (SD 22.5) minutes in the single-site group. Total operating time for the laparoscopic and single-site groups was not significantly different (111.5 minutes vs 106.0 minutes; P = .38). There were more conversions to open procedures in the laparoscopic compared to the single-site group (11 vs 1; P = .007). There were no biliary tree injuries and no deaths in either group.

Conclusion:

Single-site robotic cholecystectomy is safe to perform in an inner-city academic hospital setting. Surgical resident involvement does not adversely affect outcomes.     

Colonoscopic Perforation Management by Laparoendoscopy: An Algorithm

Background and Objectives:

The role of laparoscopy in the management of iatrogenic colonoscopic injuries has increased with surgeons becoming facile with minimally invasive methods. However, with a limited number of reported cases of successful laparoscopic repair, the exact role of this modality is still being defined. Drawing from previous literature and our own experiences, we have formulated a simple algorithm that has helped us treat colonoscopic perforations.

Methods:

A retrospective review was undertaken of patients treated for colonoscopic perforations since the algorithm''s introduction. For each patient, initial clinical assessment, management, and postoperative recovery were carefully documented. A Medline search was performed, incorporating the following search words: colonoscopy, perforation, and laparoscopy. Twenty-three articles involving 106 patients were identified and reviewed.

Results:

Between May 2009 and August 2012, 7 consecutive patients with colonoscopic perforations were managed by 2 surgeons using the algorithm. There were no complications and no deaths, with a mean length of stay of 4.43 days (range, 2–7 days). Of the 7 patients, 6 required surgery. A single patient was managed conservatively and later underwent an elective colon resection.

Conclusions:

Traditionally, laparotomy was the preferred method for treating colonoscopic perforations. Our initial experience reinforces previous views that laparoendoscopic surgery is a safe and effective alternative to traditional surgery for managing this complication. We have formulated a simple algorithm that we have found helpful for surgeons considering a laparoscopic approach to managing this condition.     

Upper Tract Urological Laparoendoscopic Single-Site Surgery (LESS)

Background and Objectives:

Our objective is to report intermediate-term outcomes for patients who have undergone upper tract urologic laparoendoscopic single-site surgery (LESS) at a single institution.

Methods:

From January 1, 2008, through November 30, 2012, 107 cases treated with LESS were identified, including pyeloplasty (n = 30), ureterolithotomy (n = 32), nephrectomy (n = 35; simple = 31, partial = 4), and cyst decortication (n = 10). Perioperative data were reviewed, and conversion and complication rates were noted.

Results:

The median follow-up was 21.5 months for pyeloplasty, 20.5 for ureterolithotomy, 28.0 for simple nephrectomy, 14.0 for partial nephrectomy, and 19.0 for cyst decortication. Major complications were encountered in 8 patients, including 3 intraoperative complications (2 bowel injury with serosal tearing and 1 intraoperative bleeding), which were recognized and repaired with LESS or conversion to conventional laparoscopy (CL). During the intermediate postoperative period (30–90 days) major complications occurred in 5 patients: 4 ureteral strictures (Clavien-Dindo grade [CG] IIIb) and 1 urinoma formation (CG IIIa). During the early postoperative period (<30 days), the most common minor complications were flank pain (CG I) in 16 patients and urinary tract infection (CG II) in 11, followed by urinary leakage (CG I) in 8.

Conclusions:

Intermediate-term functional outcomes of this single-center study confirm that upper tract LESS is a challenging procedure that can be safe and effective when performed by an experienced team. Prospective studies with longer follow-up periods are needed to investigate the safety of LESS in the treatment of various upper urinary tract conditions.     

Laparoscopic inguinal herniorrhaphy: appraisal of a cohort study

Objectives

To assess the safety and effectiveness of individualized laparoscopic herniorrhaphy and to compare its intraoperative cost to that of the standard Bassini operation.

Design

An analytic cohort study.

Setting

A university teaching hospital.

Patients

One group of 158 patients underwent 167 laparoscopic herniorrhaphies for symptomatic groin hernias. The approach was transabdominal preperitoneal for the first 124 patients and totally preperitoneal for the last 34 patients. A second group of 50 patients underwent a conventional Bassini operation.

Intervention

Individualized laparoscopic inguinal herniorrhaphy or Bassini herniorrhaphy.

Main Outcome Measures

Complications and recurrences encountered in the laparoscopic group. Total operative time and intraoperative cost involved in both procedures. Analgesia required in each group during the first 2 postoperative days.

Results

Intra- and postoperative complications of the laparoscopic approach were not life threatening. The recurrence rate at a mean follow-up of 16.8 months was 1.2%. Total operative time was significantly (p < 0.001) longer in the laparoscopy group than in the Bassini group. Patients in the Bassini group took more parenteral analgesics than those in the laparoscopy group (p = 0.02), but there was no difference with respect to the number of times enteral analgesics were required (p = 0.32). Use of mesh and staples was more expensive than sutures alone inserted laparoscopically. The Bassini procedure was a less expensive procedure than laparoscopic herniorrhaphy.

Conclusions

The laparoscopic treatment of groin hernias is safe. The recurrence rate is low. Primary unilateral inguinal hernias could be adequately treated at a lesser cost by a standard approach. Bilateral, recurrent and femoral hernias could benefit from a laparoscopic approach.
