Transvaginal Cholecystectomy without Abdominal Ports

Background:

Pioneers in natural orifice transvaginal cholecystectomy are in search of an approach that uses less percutaneous assistance. The approach must be safe and affordable. The authors present a successful cholecystectomy using a technique of transvaginal operative laparoscopy with no abdominal ports.

Methods:

A 24-year-old female patient with gallbladder lithiasis underwent a natural orifice cholecystectomy with only one transvaginal 12-mm port, using a laparoscope with a working channel. We used laparoscopic instruments 5 mm in diameter by 43cm in length (including a needle holder, Maryland dissector clamp, spatula, hook, suction cannula, and clip applier) and assistance with percutaneous marionette leashes.

Results:

The patient stayed in the hospital for 24 hours and was discharged without pain and without scars.

Conclusion:

Transvaginal cholecystectomy performed using an operative laparoscope with a working channel is possible in select cases. This technique requires no abdominal ports and is an alternative to culdolaparoscopy or hybrid transvaginal procedures with flexible endoscopes.     

Transvaginal Route for Kidney Extraction in Laparoscopic Donor Nephrectomy

Background and Objectives:

The aim of this retrospective study was to compare conventional laparoscopic living-donor nephrectomy with transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy in terms of feasibility and reproducibility.

Methods:

A total of 115 consecutive female patients who underwent laparoscopic living-donor nephrectomy (n = 70) or transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy (n = 45) were included and compared in terms of operative characteristics, as well as donor and recipient outcomes.

Results:

No significant difference was observed between the laparoscopic living-donor nephrectomy and transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy groups in terms of mean duration of warm and cold ischemia, operation time, length of hospital stay, arterial anastomoses, visual analog scale pain scores, serum creatinine levels, and receiver outcomes, whereas a significantly higher number of venous anastomoses was noted in the laparoscopic living-donor nephrectomy group than in the transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy group (P = .029).

Conclusions:

Transvaginal natural orifice transluminal endoscopic surgery–assisted living-donor nephrectomy seems to be a feasible and reproducible alternative to conventional laparoscopic living-donor nephrectomy in female donors provided the viability of the vagina as an organ retrieval route.     

Transvaginal Endoscopic Surgery for Tubal Ectopic Pregnancy

Objective:

To explore the feasibility, safety, efficacy, and cosmetic outcomes of transvaginal endoscopic salpingectomy for tubal ectopic pregnancy.

Methods:

From May 2009 to May 2012, we prospectively enrolled 40 patients, each of whom had been scheduled for a salpingectomy because of a tubal ectopic pregnancy, and randomized them into two groups: transvaginal endoscopic surgery and laparoscopic approach. We recorded the estimated blood loss, time of anal exhaust, postoperative pain score, length of stay, and scar assessment scale associated with transvaginal endoscopic access (n = 18) (natural orifice transluminal endoscopic surgery) and laparoscopic salpingectomy (n = 20) (control group) for tubal ectopic pregnancy. The transvaginal salpingectomy was performed with a double-channel endoscope through a vaginal puncture. A single surgeon performed the surgical procedures in patients in both groups.

Results:

The group that underwent the transvaginal endoscopic procedure reported lesser pain at all postoperative visits than the group that underwent the laparoscopic approach. The duration of time for transvaginal endoscopic surgery was slightly longer than that for the laparoscopic approach. However, there was no statistically significant difference between the two groups in the duration of operative time. The group that underwent transvaginal endoscopic surgery was more satisfied with the absence of an external scar than the group that underwent the laparoscopic procedure, which left a scar. The estimated blood loss, time of anal exhaust, and length of stay were the same in both groups.

Conclusion:

The safety and efficacy of transvaginal endoscopic salpingectomy for tubal ectopic pregnancy are equivalent to those of the laparoscopic procedure. Lesser postoperative pain and a more satisfactory cosmetic outcome were found with the transvaginal endoscopic procedure, making it the more preferred method and superior to the laparoscopic approach.     

Hybrid Transureteral Nephrectomy in a Survival Porcine Model

Background and Objectives:

Natural-orifice approaches for nephrectomy have included access via the stomach, vagina, bladder, and rectum. Recently, the feasibility of using the ureter as a natural orifice for natural-orifice transluminal endoscopic surgery nephrectomy has been demonstrated in a nonsurvival porcine model. The purpose of this study was to assess the outcomes of transureteral laparoscopic natural-orifice transluminal endoscopic surgery nephrectomy in a survival porcine model.

Methods:

Three pigs underwent hybrid transureteral natural-orifice transluminal endoscopic surgery nephrectomy. An experimental balloon/dilating sheath was inserted over a wire to dilate the urethra, ureteral orifice, and ureter. Through a bariatric 12-mm laparoscopic port, the ureter was opened medially and the hilar dissection was performed. Next, 2 needlescopic ports were placed transabdominally to facilitate hilar transection. The kidney was morcellated using a bipolar sealing device and extracted via the ureter using the housing of a bariatric stapling device. The ureteral orifice was closed with a laparoscopic suturing device. The bladder was drained by a catheter for 10 to 14 days postoperatively. Pigs were euthanized on postoperative day 21.

Results:

All surgical procedures were successfully completed, with no intraoperative complications. One pig had an episode of postoperative clot retention that resolved with catheter irrigation. Each pig was healthy and eating a normal diet prior to euthanasia.

Conclusions:

This study demonstrates the feasibility of a hybrid transureteral approach to nephrectomy in a survival porcine model. This technique avoids the intentional violation of a second organ system and the risk for peritoneal contamination. Improved instrumentation is needed prior to implementation in the human population.     

Natural Orifice-Assisted Laparoscopic Appendectomy

Background and Objectives:

Natural orifice transluminal endoscopic surgery involves the introduction of instruments through a natural orifice into the peritoneal cavity to perform diagnostic and therapeutic surgical interventions. We report the utilization of the vaginal opening at the time of laparoscopic-assisted vaginal hysterectomy or total laparoscopic hysterectomy as a natural orifice for appendectomy.

Methods:

We reviewed cases of 42 patients who underwent total laparoscopic hysterectomy or laparoscopic-assisted vaginal hysterectomy followed by appendectomy, performed by applying a stapler and removing the appendix transvaginally. By using a small-diameter laparoscope, the appendix was mobilized, especially in patients with adhesions, endometriosis, or retrocecal appendix, to facilitate transvaginal access with the stapler.

Results:

All procedures were performed successfully without intraoperative or major postoperative complications. The appendectomy portion of the procedure took approximately 5 minutes to 10 minutes. Appendiceal pathology included serosal adhesions (14), fibrous obliteration of the lumen (12), endometriosis (4), serositis (2), and carcinoid tumor (1), among others.

Conclusions:

Appendectomy performed with an endoscopic stapler introduced transvaginally for amputation and retrieval following total laparoscopic hysterectomy or laparoscopically assisted vaginal hysterectomy appears to be a safe and effective modification of established techniques with acceptable outcomes.     

Methods of safe laparoscopic cholecystectomy for left-sided (sinistroposition) gallbladder: A report of two cases and a review of safe techniques

INTRODUCTION

Left-sided gallbladder is a rare anatomical variation. Usually it is discovered intra-operatively and is accompanied by anatomic variations that can prove quite challenging during laparoscopy.

PRESENTATION OF CASE

From a total of almost 3000 laparoscopic cholecystectomies performed in our institution, two cases of left sided gallbladder were unexpectantly identified intraoperatively. There were no indications for the ectopy preoperatively. In both cases modifications of the standard laparoscopic technique were mandatory. They were performed safely with no post-operative complications. Modifications consisted of transposition of the subxiphoid entry port and alteration in the direction of traction of the rest of the graspers. A review of the literature for methods of safe laparoscopic cholecystectomy was conducted.

DISCUSSION

The surgeon must be aware of the anatomic variances in the rare occasion of a left sided gallbladder, since preoperative diagnosis is very difficult.

CONCLUSION

Knowledge of potential hazards and modifications of laparoscopic technique is mandatory in order to avoid complications.     

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.     

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.     

Conversion to Stoppa Procedure in Laparoscopic Totally Extraperitoneal Inguinal Hernia Repair

Background and Objectives:

Conversion to open surgery is an important problem, especially during the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair.

Methods:

Here, we discuss conversion to the Stoppa procedure during laparoscopic TEP inguinal hernia repair. Outcomes of patients who underwent conversion to an open approach during laparoscopic TEP inguinal hernia repair between September 2004 and May 2010 were evaluated.

Results:

In total, 259 consecutive patients with 281 inguinal hernias underwent laparoscopic TEP inguinal hernia repair. Thirty-one hernia repairs (11%) were converted to open conventional surgical procedures. Twenty-eight of 31 laparoscopic TEP hernia repairs were converted to modified Stoppa procedures, because of technical difficulties. Three of these patients underwent Lichtenstein hernia repairs, because they had undergone previous surgeries.

Conclusion:

Stoppa is an easy and successful procedure used to solve problems during TEP hernia repair. The Lichtenstein procedure may be a suitable option in patients who have undergone previous operations, such as a radical prostatectomy.     

Villous Mucinous Cystadenoma of the Appendix in a Postmenopausal Woman

Objective:

To present the case of a postmenopausal woman, who was suspected of having an ovarian cyst. Instead, a cystadenoma of the appendix was discovered during laparoscopy.

Methods:

A 64-year-old postmenopausal nulliparous woman was admitted to our hospital because of a cystic lesion, which had been detected in the course of a routine gynecological examination. The patient underwent vaginal ultrasound, magnetic resonance tomography, and laparoscopy.

Results:

During vaginal ultrasound, a dumbbell-shaped anechogenic cystic structure 70 × 32 × 22 mm in diameter was found in the region of the right adnexa. Magnetic resonance tomography revealed no additional information. During diagnostic laparoscopy, the cystic lesion was found to be a distended appendix. A laparoscopic appendectomy was performed. Subsequent histological analysis revealed a villous mucinous cystadenoma of the appendix with low-grade intraepithelial neoplasia.

Conclusion:

Gynecologists should routinely consider this disease in the differential diagnosis of right lower dumbbell abdominal cysts. Eleven percent to 20% of mucoceles are caused by mucinous cystadenocarcinomas, which carry the risk of peritoneal tumor implantation caused by rupture or laparoscopic resection. Therefore, it should be mandatory that a general surgeon be involved in the laparoscopic procedure and the conversion to laparotomy for resection of the structure.     

Laparoscopic Cholecystectomy and Newer Techniques of Gallbladder Removal

Objectives:

To describe the surgical complications associated with laparoscopic cholecystectomy, as performed by a single surgeon over an 8-year period and to discuss how this compares to newer methods of cholecystectomy, such as single-incision surgery and natural orifice transluminal endoscopic surgery.

Methods:

The charts of 1000 consecutive patients who underwent consecutive cholecystectomies were reviewed to gather the following information: age, sex, prior abdominal procedures, type of procedure performed (laparoscopic vs open, with or without cholangiography), pre and postoperative diagnosis, and complications directly related to surgical technique, such as biliary injury, bile leak, infection, trocar-related injury, and incisional hernia.

Results:

The laparoscopic approach was attempted in all but one patient and was successful in 94.1% of patients. The conversion rate was higher with acute cholecystitis than with other forms of biliary tract disease. Successful cholangiography was accomplished in over 97% of patients. Nineteen complications directly related to the surgical procedure were found, including one bile duct injury.

Conclusion:

Laparoscopic cholecystectomy continues to offer a safe and effective treatment for patients with symptomatic biliary tract disease. Although other forms of minimally invasive cholecystectomy are being studied, there is little data to suggest any additional benefit, other than a slight improvement in cosmesis. Until larger series demonstrate that these techniques have a complication rate similar to those cited in the surgical literature, traditional 4-port laparoscopic cholecystectomy should remain the standard of care.     

Vascular Complications Following Laparoscopy: Two Unusual Cases

Background:

Vascular complications following laparoscopic techniques may often be attributed to the incomplete control of bleeding sites at laparoscopy. When con-fronted with post-laparoscopy symptoms of hemodynamic insufficiency, the surgeon may infer the existence of hemorrhagic complications neglected at the laparoscopic session.

Methods:

The author reviewed two otherwise normal cases of laparoscopic procedures that were complicated by bleeding disorders of unknown origin.

Results:

Diagnosis and treatment of the hematologic complications revealed causes other than operator-inflicted injury.

Conclusions:

While laparoscopists should remain vigilant concerning the very real threat of overlooked vascular injury following laparoscopy, some patients may exhibit hemorrhagic symptoms unrelated to the laparoscopic procedure.     

Novel Port Placement and 5-mm Instrumentation for Robotic-Assisted Hysterectomy

Background and Objectives:

The value of robotic surgery for gynecologic procedures has been critically evaluated over the past few years. Its drawbacks have been noted as larger port size, location of port placement, limited instrumentation, and cost. In this study, we describe a novel technique for robotic-assisted laparoscopic hysterectomy (RALH) with 3 important improvements: (1) more aesthetic triangular laparoscopic port configuration, (2) use of 5-mm robotic cannulas and instruments, and (3) improved access around the robotic arms for the bedside assistant with the use of pediatric-length laparoscopic instruments.

Methods:

We reviewed a series of 44 women who underwent a novel RALH technique and concomitant procedures for benign hysterectomy between January 2008 and September 2011.

Results:

The novel RALH technique and concomitant procedures were completed in all of the cases without conversion to larger ports, laparotomy, or video-assisted laparoscopy. Mean age was 49.9 years (SD 8.8, range 33–70), mean body mass index was 26.1 (SD 5.1, range 18.9–40.3), mean uterine weight was 168.2 g (SD 212.7, range 60–1405), mean estimated blood loss was 69.7 mL (SD 146.9, range 20–1000), and median length of stay was <1 day (SD 0.6, range 0–2.5). There were no major and 3 minor peri- and postoperative complications, including 2 urinary tract infections and 1 case of intravenous site thrombophlebitis. Mean follow-up time was 40.0 months (SD 13.6, range 15–59).

Conclusion:

Use of the triangular gynecology laparoscopic port placement and 5-mm robotic instruments for RALH is safe and feasible and does not impede the surgeon''s ability to perform the procedures or affect patient outcomes.     

Scarless hepatectomy: natural orifice specimen extraction after left lateral sectionectomy

Background

The use of laparoscopy in liver surgery is well established and considered as the gold standard for small resections. The laparoscopic resections have lower morbidity and better cosmetic results, but still require an incision to remove the surgical specimen. The possibility of remove the specimen through natural orifices and avoid an abdominal incision may further improve the benefits offered by minimally invasive procedures.

Aim

To describe the technique of transvaginal extraction of the specimen after laparoscopic liver left lateral sectionectomy.

Method

The laparoscopic liver resection is performed in a standard fashion. After completing the resection, the specimen is placed into a retrieval plastic bag. To perform de extraction, a vaginal colpotomy is performed, guided by a 12 mm trocar introduced through the vagina. Then the extraction bag is removed pulling the bag through the extended incision in the posterior wall of the vagina. After the extraction, the colpotomy incision is closed laparoscopically.

Results

This technique was performed in a 74-year-old woman with a 3 cm lesion between liver segments 2 and 3. She had a fast and uneventful recovery.

Conclusion

This technique appears to be feasible, safe and avoid the complications of an abdominal incision.     

Hand-Assisted Laparoscopic Transhiatal Esophagectomy Using the Dexterity Pneumo Sleeve

Background:

As the use of laparoscopic techniques have expanded to more complicated procedures, limitations of laparoscopy have begun to be realized. To help regain the ability to palpate and bluntly dissect tissues, and handle larger organs, surgeons have begun to utilize devices which allow the surgeon''s hand to be inserted into the abdomen during laparoscopic procedures. One such device is the Dexterity Pneumo Sleeve, which was used here to perform transhiatal esophagectomy in two patients.

Methods:

Two patients with adenocarcinoma of the esophagus underwent hand-assisted laparoscopic transhiatal esophagectomy. The stomach mobilization was carried out using laparoscopic technique facilitated by the use of the surgeon''s hand. Blunt dissection of the esophagus through the hiatus was then carried out. Dissection of the proximal esophagus and creation of a cervical esophagogastric anastomosis was then performed in the neck through a cervical incision.

Results:

The Pneumo Sleeve proved useful for handling the stomach, as well as, blunt dissection of the esophagus while still maintaining the benefits of laparoscopy, including small incisions, and no postoperative ileus.

Conclusion:

Hand-assisted laparoscopic esophagectomy can be carried out with good, early, postoperative recovery.     

Laparoscopy Shortens Length of Stay in Patients With Gastric Electrical Stimulators

Background:

Gastric electrical stimulation has been proven effective for drug-refractory gastroparesis. Placement of stimulator leads and device usually requires a laparotomy, although laparoscopic placement has also been used.

Methods:

To compare laparotomy with laparoscopy, we examined 36 patients, 18 undergoing laparoscopy and 18 undergoing laparotomy, matched for primary diagnosis and health resource usage. We compared baseline symptoms, length of surgery, length of postoperative hospital stay, gastric emptying, and health resources in each of the 2 groups over time, to see what variables, if any, differed.

Results:

Baseline symptoms, gastric emptying, and health resource usage were similar. Operative times were also similar, but length of stay declined from a mean of 6.4 days for laparotomy to 1.1 days for laparoscopy. Long-term outcome, via symptoms, gastric emptying, and health resource utilization were comparable between the 2 groups.

Conclusion:

Laparoscopic placement of gastric electrical stimulator leads and device is associated with shorter lengths of postoperative hospital stay. However, the patients who underwent laparotomy had higher vomiting scores and more previous abdominal surgeries at baseline, and higher long-term mortality at follow-up, suggesting that they may be more ill, as a group, than the laparoscopic patients. Laparoscopic placement of devices may be preferable when technically feasible.     

Morgagni hernia treated by reduced port surgery

INTRODUCTION

The laparoscopic repair of a rare diaphragmatic Morgagni hernia using the reduced port approach is described.

PRESENTATION OF CASE

An 85-year-old female presented with a 2 days history of upper abdominal discomfort and loss of appetite. We diagnosed her condition as a Morgagni hernia by morphological studies and performed laparoscopic mesh placement with a multi-channel port and 12-mm port. This elderly patient had a rapid postoperative recovery. A 2-year follow-up CT showed no recurrence of the hernia.

DISCUSSION

Recent trends in laparoscopic procedures have been toward minimizing the number of incisions to reduce invasiveness. This case indicated that the reduced port approach can be considered a suitable and safe procedure for treatment of Morgagni hernia.

CONCLUSION

The reduced port approach is a good indication for Morgagni hernia.     

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.     

UREKA: umbilical ring easy kannula access

Background and Objectives:

Standard techniques of laparoscopic access involve creating an abdominal wall defect and can result in complications. We describe the umbilical ring easy kannula access (UREKA) technique, evaluating safety and a decrease in complications related to port placement.

Methods:

UREKA is performed via a supra- or infraumbilical incision followed by circumferential dissection of the umbilical stalk. The umbilical skin is dissected free from the fascia, exposing the umbilical ring. Pneumoperitoneum is established either before or after placement of a dilating port through the open ring. We reviewed all laparoscopic procedures performed by one pediatric surgeon over 14 months using UREKA.

Results:

Ninety-four patients underwent laparoscopic surgery with initial port placement via UREKA. Appendectomy (n=57) was the most common procedure, followed by fundoplication (15) and cholecystectomy (10). No intestinal, solid organ, vascular, or bladder injuries related to port placement occurred. The only postoperative complication was a superficial wound infection in a 135-kg patient following cholecystectomy, treated successfully with oral antibiotics alone.

Conclusion:

The umbilical ring persists to some degree in all pediatric patients and provides a safe portal of entry for laparoscopic surgery. UREKA has few complications and is a straightforward, reproducible technique for gaining initial laparoscopic access.     

Incidence of Port-Site Incisional Hernia After Single-Incision Laparoscopic Surgery

Background and Objectives:

Single-incision laparoscopic surgery is gaining popularity among minimally invasive surgeons and is now being applied to a broad number of surgical procedures. Although this technique uses only 1 port, the diameter of the incision is larger than in standard laparoscopic surgery. The long-term incidence of port-site hernias after single-incision laparoscopic surgery has yet to be determined.

Methods:

All patients who underwent a single-incision laparoscopic surgical procedure from May 2008 through May 2009 were included in the study. Single-incision laparoscopic surgical operations were performed either by a multiport technique or with a 3-trocar single-incision laparoscopic surgery port. The patients were seen at 30 to 36 months'' follow-up, at which time they were examined for any evidence of port-site incisional hernia. Patients found to have hernias on clinical examination underwent repairs with mesh.

Results:

A total of 211 patients met the criteria for inclusion in the study. The types of operations included were cholecystectomy, appendectomy, sleeve gastrectomy, gastric banding, Nissen fundoplication, colectomy, and gastrojejunostomy. We found a port-site hernia rate of 2.9% at 30 to 36 months'' follow-up.

Conclusion:

Port-site incisional hernia after single-incision laparoscopic surgical procedures remains a major setback for patients. The true incidence remains largely unknown because most patients are asymptomatic and therefore do not seek surgical aid.
