Trocar site hernia after laparoscopic colectomy: a case report and literature review

In-bag extraction of tissue through an incision in the posterior vaginal wall in laparoscopic myomectomy: a large retrospective study

BACKGROUND

Our purpose was to describe the outcomes of transvaginal in-bag tissue extraction tissue through an incision in the posterior vaginal wall the middle part incision of posterior vagina in laparoscopic myomectomy.

METHODS

This was a retrospective study of patients who received laparoscopic myomectomy and in-bag tissue extraction through an incision in the posterior vaginal wall between January 2016 and December 2022. Patient characteristics, intra- and post-operative complications, and outcomes were collected and analyzed.

RESULTS

A total of 511women were included in the analysis. The mean largest myoma diameter was 8.44 ± 3.56 cm; mean specimen weight was 789.23 ± 276.97 g; mean operative time was 129.01 ± 53.13minutes; and mean blood loss was 175.99 ± 210.96 mL. Within 30-days of surgery, no fever, infection, or vaginal bleeding was noted in any patient, and the vaginal incisions of all patients had healed well. There were no incisional hernias, pelvic infections, and vaginal adhesions noted at follow-up 3 months after the operation. There were 37 cases of vaginal delivery of the patients after surgery, and there were no lacerations of the posterior wall vaginal incision.

CONCLUSIONS

Transvaginal in-bag extraction though an incision in the posterior vaginal wall is feasible and safe for removing tissue after laparoscopic myomectomy.

Port Site Obstructed Hernia in a Morbidly Obese Patient: A Case Report

Indications for laparoscopic surgeries are increasing in the current era in view of the advantages they offer in terms of less perioperative morbidities, early mobilization, and better cosmesis. These benefits are perceived even more in obese women. However, there are special challenges in this population, associated with their body habitus, poor visibility, and perioperative anesthesia risks. Difficulty in port closure is one such problem encountered in these women causing inadequate rectus suturing and leading to port site hernia. We report a case of a 59-year-old morbidly obese lady who underwent a total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node dissection for carcinoma endometrium. The intraoperative course was uneventful. In the postoperative period, she developed acute obstruction due to port site herniation of the small bowel, which was not suspected till postoperative day five. This was due to an inaccurate assessment of her abdomen because of her body habitus. A CT scan was done in view of the non-resolving obstruction, which revealed herniation of a small bowel loop through the umbilical port. Immediate correction was resorted to under local anesthesia. Rectus sheath closure was done in the same sitting. The patient had a quick recovery after that and was discharged three days later. Rectus sheath closure should be done for all ports 10 mm or greater in diameter. There should be a low threshold to get cross-sectional imaging in postoperative obese women with non-resolving gastrointestinal symptoms.

Is fascial closure required for a 12-mm trocar? A comparative study on trocar site hernia with long-term follow up

BACKGROUND

Despite the infrequency of trocar site hernias (TSHs), fascial closure continues to be recommended for their prevention when using a ≥ 10-mm trocar.

AIM

To identify the necessity of fascial closure for a 12-mm nonbladed trocar incision in minimally invasive colorectal surgeries.

METHODS

Between July 2010 and December 2018, all patients who underwent minimally invasive colorectal surgery at the Minimally Invasive Surgery Unit of Siriraj Hospital were retrospectively reviewed. All patients underwent cross-sectional imaging for TSH assessment. Clinicopathological characteristics were recorded. Incidence rates of TSH and postoperative results were analyzed.

RESULTS

Of the 254 patients included, 70 (111 ports) were in the fascial closure (closed) group and 184 (279 ports) were in the nonfascial closure (open) group. The median follow up duration was 43 mo. During follow up, three patients in the open group developed TSHs, whereas none in the closed group developed the condition (1.1% vs 0%, P = 0.561). All TSHs occurred in the right lower abdomen. Patients whose drains were placed through the same incision had higher rates of TSHs compared with those without the drain. The open group had a significantly shorter operative time and lower blood loss than the closed group.

CONCLUSION

Routine performance of fascial closure when using a 12-mm nonbladed trocar may not be needed. However, further prospective studies with cross-sectional imaging follow-up and larger sample size are needed to confirm this finding.

Comparison of two fascial defect closure methods for laparoscopic incisional hernia repair

PURPOSE

Currently there is no consensus regarding the optimal surgical approach to an incisional hernia measuring less than 10 cm. Certain hernia features including defect size, intra-abdominal adhesions, and overlying scar/skin properties contribute to choosing an open versus a laparoscopic approach. This retrospective cohort study was designed to compare incisional hernia defects repaired with laparoscopic suture closure to a hybrid approach with open defect closure, both with laparoscopic intraperitoneal onlay mesh (IPOM) reinforcement.

METHODS

We identified 164 consecutive patients who underwent incisional hernia repair from two centers, North York General Hospital (NYGH) and Humber River Hospital (HRH) between 2015 and 2020. Patients were grouped by totally laparoscopic or hybrid fascial closure. Both techniques included laparoscopically placed intra-peritoneal mesh with 5 cm of overlap in all directions. Patients were analyzed by age, sex, body mass index (BMI), ASA class and hernia size. Primary outcomes included surgical site infection (SSI), other wound complications including seroma/hematoma, length of hospital stay, pain reported at follow-up appointment, and hernia recurrence.

RESULTS

Post-operative pain, surgical site infections and seromas did not differ between the totally laparoscopic and hybrid approach. The recurrence rates were 5.8% and 6.8% for the laparoscopic and hybrid group, respectively, which were not significantly different. The time to recurrence was 15 months (range 8-12) in the laparoscopic group and 7 months (range 6-36) in the hybrid group, also not significantly different. The hernia defect size and BMI were significantly higher in the hybrid group, without increased wound complications.

CONCLUSION

These results suggest that a hybrid approach to incisional ventral hernia repair with open defect closure is comparable to a totally laparoscopic closure. The hybrid technique can help facilitate fascial closure and resection of the hernia sac in patients with higher BMI and hernia defects up to 6 cm.

Trocar-Related Safety Events in Minimally Invasive Surgical Procedures: Risks for Organ and Vascular Complications

A trocar is a hollow device used during minimally invasive surgery that serves as an entry port for optical scopes and surgical equipment. Insertion of this device into the body is determined using anatomical landmarks taking into consideration the patient’s history and physical attributes, e.g., scars or abdominal size. Insertion of the first trocar is the time of highest risk of injury. Intestinal and vascular injuries are two potentially life-threatening injuries that can occur. A retrospective review of trocar-related events submitted to the Pennsylvania Patient Safety Reporting System (PA-PSRS) between January 1, 2014, and June 30, 2020, identified 268 events. Internal organ and vascular injuries accounted for 81.0% of events; trocar site skin integrity injuries, bleeding/hemorrhage, and hernias accounted for 17.2% of events; and vasovagal responses accounted for 1.9% of events. Internal injuries occurring during the initial insertion of the trocar, Veress needle, or incision in preparation for a trocar insertion was reported in 64.5% of events. Adhesions were identified in 13.5% of internal injury events. Many internal injury events identified a single injury; however, in 17 instances patients sustained two trocar-related injuries. Conversion to open surgery, return to the operating room during the same admission, postoperative intensive care unit admission, ambulatory surgical facility transfer to a hospital, readmission, postdischarge return to the operating room, and death are outcomes identified in the event reports.

Does closure of fascia, type, and location of trocar influence occurrence of port site hernias? A literature review

BACKGROUND

Since the introduction of laparoscopic surgery, it has become more popular with many advantages over open surgery including faster recovery, shorter hospital stays, and decreased tissue trauma. Despite its benefits, laparoscopic surgery can result in its own unique complications, such as the formation of a trocar site hernia (TSH), which have been reported in approximately 0-1.0% of laparoscopic cases when using non-bladed trocars.

METHODS

A literature review was performed from June 1990 to June 2019. PubMed was searched using the keywords "laparoscopic surgery," "trocar site hernia," and "port site hernia." Only articles in English were identified but not limited to the USA.

RESULTS

The total number of patients in all articles was 18,533 with a mean follow-up period of 22.50 ± 1.76 months. The overall trocar site hernia rate was 0.104%. When comparing open vs. closed ports, there was no significant difference in the hernia incidence rate for 5-mm and 10-mm ports. When comparing bladed versus non-bladed trocars left open, there was a statistically significant difference with lower hernia incidence rates for non-bladed trocars over bladed trocars for 5-mm, 10-mm, and 12-mm ports. And when comparing trocar location from midline versus off-midline, there was a statistically significant higher TSH incidence in midline trocar locations.

CONCLUSION

Results suggest that TSH rate is lower when using non-bladed trocars for any size of trocar. When comparing whether fascial closure had an effect, the 5-mm and 10-mm ports had no difference in incidence rates and leaving the fascia open can reduce operative time, risk of needlestick injuries, and overall procedural cost. In addition, trocars at midline locations resulted in higher TSH incidence rates. Future research is still needed to assess for other factors that may influence hernia formation and how it can be minimized.

Five-Millimetre Trocar Site Herniation as a Late Complication After Six Years Following Laparoscopic Appendectomy in Nine-year-old Boy

Trocar site hernia (TSH) is a type of incisional hernia occurring at the trocar sites after minimal invasive surgeries, most often in adult patients with non-sutured trocar sites. This is a case report of a 5 mm trocar site omental herniation six years after laparoscopic appendectomy in a nine-year-old boy to emphasize that incisions should be closed using fascial and cutaneous sutures, regardless of trocar size and localization, to prevent TSH. We conducted a brief review of the literature on this topic.

Transabdominal versus transvaginal specimen extraction in mini-laparoscopic surgery

AIM

The objective of this study was to present our experiences of tissue extraction via the transvaginal (TV) route after a mini-laparoscopic gynecological surgery and compare them with our transabdominal (TA) specimen extraction experiences.

METHODS

This prospective randomized controlled study was conducted in a tertiary care center between July 2014 and February 2016. Fifty-eight women who were undergoing mini-laparoscopy for adnexal mass removal were randomized into two groups according to the surgical specimen removal by the TV route (n = 28) or the TA route (n = 30). The main outcome measures were the postoperative incisional pain, cosmetic outcomes and overall satisfaction rate. The secondary outcome measures were additional blood loss, additional operation duration and the need for morcellation.

RESULTS

The TV group had significantly lower visual analog scale scores than the TA group at 6 and 24 h postoperatively. The morcellation needs were lower in the TV group than in the TA group. Three months after the surgery, the participants scored a higher rate of overall satisfaction in the cosmetic outcomes in the TV group than in the TA group.

CONCLUSION

Tissue extraction through a posterior colpotomy after mini-laparoscopic surgery may be a feasible technique for improving cosmetic results, decreasing postoperative pain and decreasing the need for morcellation when compared to TA specimen retrieval.

No Need of Fascia Closure to Reduce Trocar Site Hernia Rate in Laparoscopic Surgery: A Prospective Study of 200 Non-Obese Patients

Background

Laparoscopy is widely practiced and offers realistic benefits over conventional surgery. Port closure is important after a laparoscopic procedure to prevent port site incisional hernia. Larger port size and increasing numbers of ports needed to perform more complex laparoscopic procedures are likely to increase the incidence of port site hernias (PSHs). PSHs tend to develop more frequently at umbilical and midline port sites due to the thinness of the umbilical skin and weaknesses in the linea alba. More than 90% of PSHs occur through 10 mm and large ports can occur through 5 mm ports also. The aim was to study the outcomes and complications in laparoscopic surgery without fascial sheath closure of port site. We compared the results with another group in which fascial closure was done by a standard method.

Methods

This was a prospective study carried out in the Department of Surgery, MMIMSR, Mullana, Ambala, from August 2013 to 2015 in a single unit by a single surgeon. A total of 200 patients were selected randomly for the different laparoscopic procedures. Patients were divided into group A (only skin closure was done without fascia closure) and group B (fascial closure of the port in addition to skin closure). In both groups, we used blunt trocar for the 10 mm port. Skin of the 5 mm port was closed simply. The results in two groups were compared in terms of complications like PSH, bleeding, and wound infection.

Results

The outcomes in two groups were compared with and without fascia closure of 10 mm trocar port site. Patients operated for lap cholecystectomy were 170 (85%), 10 (5%) for lap appendicectomy, and 20 (10%) for lap hernia. The study compared the results in two groups mainly for PSH formation. The P value was insignificant and Fischer’s exact test result came as 1.00. There were no significant differences between the two groups in terms of PSH, bleeding and infection in non-obese cases.

Conclusion

In both groups, blunt trocar was introduced into the abdomen. We concluded that this is safe, without visceral injury, and no bleeding was seen in both the groups. We had not encountered any case with PSH formation in follow-up of 6 - 8 months. There was no infection over the port site.

The Earliest Presenting Umbilical Port Site Hernia Following Laparoscopic Cholecystectomy: A Case Report

Port site hernia after laparoscopic surgery is a rare complication. Here we present a case of a 55-year-old female, diagnosed with an anterior abdominal wall hernia through the 10mm umbilical port, just two days after her laparoscopic cholecystectomy. The uniqueness of this case is its extremely early presentation. Patient presented with features of acute intestinal obstruction and due to prompt diagnosis and timely intervention, she underwent a successful reduction of hernia and an anatomical repair of the fascial and peritoneal defect through the midline laparotomy incision.

Minilaparoscopic versus standard laparoscopic hysterectomy for uteri ≥ 16 weeks of gestation: surgical outcomes, postoperative quality of life, and cosmesis

OBJECTIVE

Hysterectomy for enlarged uteri is a surgical challenge. Our aim was to compare perioperative outcomes, cosmesis, and postoperative quality of life following laparoscopic hysterectomy for large uteri using minilaparoscopic 3-mm versus conventional laparoscopic 5-mm instruments.

SUBJECTS AND METHODS

We prospectively enrolled women with a uterus between 16 and 20 weeks of gestation at the preoperative examination. These patients underwent laparoscopic procedures using either 3-mm (minilaparoscopy group) or 5-mm (standard laparoscopy group) instruments. Five months after surgery, patients were called back to fill out the validated Italian translation of the Short Form 12-item Health Survey. Data about the cosmetic outcome of the procedure were also collected, using a Numeric Rating Scale (NRS) from 0 to 10.

RESULTS

Seventy-eight women were included (27 in the 3-mm and 51 in the 5-mm groups). Perioperative characteristics were comparable between groups. The median uterus weight was 575 (range, 440-1050) g and 550 (400-1000) g in the 3-mm and 5-mm groups, respectively. No minilaparoscopic procedure was converted to standard 5-mm or to an open approach. One (2%) conversion to open abdominal surgery was needed in the conventional laparoscopy group. A better subjective cosmetic outcome was found in the 3-mm (NRS, 9.7 ± 0.4) versus the 5-mm (NRS, 8.9 ± 1.2) group (P=.01). Postoperative quality of life was comparable between groups.

CONCLUSIONS

Minilaparoscopic hysterectomy is feasible, even in the case of an enlarged-size uterus. Moreover, it is associated with a better cosmetic outcome, compared with conventional laparoscopy.

The influence of laparoscopy on incisional hernia rates: a retrospective analysis of 1057 colorectal cancer resections

AIM

The aim of this study was to evaluate the incidence of incisional hernia formation after laparoscopic and open surgery for colorectal cancer.

METHOD

A retrospective analysis was conducted of 1057 colorectal cancer resection cases (289 laparoscopic, 768 open) performed in a single national laparoscopic training centre between January 2006 and December 2011. Clinical notes and serial computed tomography scans were reviewed, with any incisional hernia including those at a surgical incision, port site, stoma and stoma closure site identified and the size of the defect measured.

RESULTS

The overall incisional hernia rate was 14.8%. There was no significant difference between the open and laparoscopic groups (14.4% vs 15.9%, P = 0.566). Excluding stoma-related hernia, 10.7% of the open group developed a surgical wound hernia, and 11.1% of the laparoscopic group developed a hernia at a port site, extraction site or surgical midline incision. There was no statistical difference between the two groups (P = 0.853). The defects were smaller in the laparoscopic group (P < 0.005). There were significantly more parastomal hernias in the laparoscopic group (40%) than in the open group (12.7%, P < 0.001).

CONCLUSION

The incidence of incisional hernia formation was similar after laparoscopic or open surgery for colorectal cancer. Parastomal hernia was more frequent after laparoscopic surgery.

Case Series of Umbilical and Extra-umbilical Port Site Herniae

Trocar site hernia or port site hernia (PSH) is a type of incisional hernia occurring at the trocar sites after laparoscopic surgeries. This is a rare but a potentially dangerous complication, as it can lead to considerable morbidity requiring surgical intervention. Various factors have been implicated for its development and various methods are also suggested for its prevention. We present here five cases of port site herniae.

Nerve-sparing minilaparoscopic versus conventional laparoscopic radical hysterectomy plus systematic pelvic lymphadenectomy in cervical cancer patients

AIM

To present our preliminary experience with nerve-sparing minilaparoscopic radical hysterectomy plus pelvic lymphadenectomy for the surgical treatment of cervical cancer and to compare outcomes with those of the conventional laparoscopic approach.

METHODS

Data of 87 consecutive women who underwent minimally invasive surgery for early and locally advanced stage cervical cancer were prospectively collected. Ten women who underwent laparoscopic surgery using a nerve-sparing technique performed through 3-mm ancillary ports were compared with the 77 patients who had standard laparoscopic surgery previously with 3 sovrapubic 5-mm trocars.

RESULTS

Minilaparoscopic radical hysterectomy was successfully accomplished in every case with no conversion to standard laparoscopy or open surgery. Two (2.6%) conversions to open surgery occurred in the conventional laparoscopy group. Surgical characteristics (operative time, estimated blood loss, and length of stay) and complication rate were similar between the 2 groups. No differences in the amount of parametrial and vaginal tissue removed were observed. The number of lymph nodes retrieved through minilaparoscopy was higher than conventional laparoscopy (30 [range = 26-38] vs 22 [range = 8-49]; P = .002). However, no difference was observed when the analysis was restricted to the last 10 conventional procedures (30 [range = 26-38] vs 29 [range = 24-49]; P = .81).

CONCLUSIONS

Our data show that minilaparoscopic radical hysterectomy with pelvic lymphadenectomy is a feasible procedure if performed by skilled surgeons.

Transvaginal specimen extraction at laparoscopy without concomitant hysterectomy: our experience and systematic review of the literature

STUDY OBJECTIVE

The modality of surgical specimen extraction is extremely important in the setting of minimally invasive operations. To assess the feasibility, safety, and applicability of transvaginal specimen extraction through posterior colpotomy in women with uterus in situ, we present our 11-year experience with this technique and perform a systematic review of the available studies in the field of gynecologic laparoscopy.

DESIGN

A retrospective analysis and systematic review of the literature (Canadian Task Force classification II-2).

SETTING

A tertiary care center.

PATIENTS

Two hundred thirty women with uterus in situ undergoing minimally invasive surgery for gynecologic disease at our institution with transvaginal specimen removal in the period between 2001 and 2012. We then reviewed 17 studies, collecting data on a total of 899 transvaginal retrieval procedures.

INTERVENTIONS

Transvaginal specimen retrieval after operative laparoscopy.

MEASUREMENTS AND MAIN RESULTS

Overall, 259 retrieval procedures were performed in the 230 patients operated on at our institution (including extraction of adnexal specimens [n = 190], uterine myomectomies [n = 36], bowel resections [n = 17], and other [n = 16]). All interventions were completed laparoscopically. Two (0.8%) women required secondary surgery because of postoperative intraperitoneal bleeding. Three additional (1.3%) minor postoperative complications were observed. No intra- and postoperative complications associated with the extraction technique occurred. In our literature review, a total of 58 (6.5%) complications were recorded. Only 1 (0.1%) adverse event was related to the transvaginal extraction procedure.

CONCLUSION

Our data suggest that transvaginal specimen retrieval after operative laparoscopy represents a safe, feasible, and applicable technique. Further research is needed to assess the real advantages of this natural orifice extraction procedure.

Laparoscopy in colorectal surgery

Laparoscopic colorectal surgery may be comparable with open techniques when considering oncological and long-term follow-up outcomes; however, there are a few operative complications specific to laparoscopic colorectal surgery. This article reviews the array of complications and discusses them in detail.

Transanal hybrid colon resection: from laparoscopy to NOTES

BACKGROUND

Reducing access size and trauma are important issues in natural orifice transluminal endoscopic surgery (NOTES). The combination of experience with laparoscopic colorectal surgery and transanal endoscopic microsurgery has helped in the use of the transanal approach as a realistic option of NOTES techniques to introduce transanal hybrid laparoscopic-assisted colon resection into clinical practice. The purpose of this study was to assess the clinical introduction of transanal hybrid colon resection in terms of feasibility and patient safety.

METHODS

Patients with pelvic floor disorders, prolapse, and slow-transit constipation in whom a colon resection was indicated were recruited. Patients were followed prospectively with a postoperative well-being score, a pain score, and a quality-of-life score. All complications were prospectively documented. The essential change was the reduction of the number and size of ports by using the transanal route. A camera and two 5-mm ports for grasping forceps and delivering ultrasonic energy were the laparoscopic components. All tasks requiring a port diameter of >5 mm were applied via the transanal route, such as positioning of the proximal stapler anvil, application of linear stapling for resection, specimen retrieval, stapler anastomosis, and closing the bowel.

RESULTS

Fifteen patients with benign colorectal disease underwent transanal hybrid colon resection, and 11 had additional rectopexy. All patients were women with a mean age of 61 (range, 28-86) years and a body mass index of 26 kg/m(2). One patient was converted to full laparoscopy. One complication--bleeding that required no reintervention--was recorded. The procedure lasted a mean of 131 (range, 55-184) min. The Gastrointestinal Quality of Life Index was 96 before surgery and 117 after surgery.

CONCLUSIONS

From this initial experience, transanal hybrid colon resection seems a feasible and safe hybrid NOTES procedure that can be usefully introduced into clinical practice.
