Efficacy of transumbilical laparoendoscopic single-site surgery versus multi-port laparoscopic surgery for endometrial cancer: a retrospective comparison study

Background

Although single-port laparoscopy surgery has been evaluated for several years, it has not been widely adopted by gynecologic oncologists. The objective was to compare the perioperative outcomes and survival of endometrial cancer (EC) patients undergoing transumbilical laparoendoscopic single-site surgery (TU-LESS) with multi-port laparoscopic surgery (MLS).

Materials and methods

This is a retrospective comparative monocentric study including patients treated between December 2017 and October 2021. The perioperative outcomes and survival of EC patients who had surgery via TU-LESS or MLS were compared, by propensity matching.

Results

A total of 156 patients were included (TU-LESS vs. MLS: 78 vs. 78). The conversion rate of TU-LESS and MLS was 5.13% and 2.56%, respectively (P=0.681). The operation time was comparable between the two groups [207.5min (180-251) vs. 197.5min (168.8-225), P=0.095]. There was no significant difference between the two groups in exhaustion time, perioperative complications, or postoperative complications. While, the TU-LESS group had a shorter out-of-bed activity time [36 hours (24-48) vs. 48 hours (48-72), P<0.001] and a lower visual analog pain scale 36 hours after surgery [1 (1-2) vs. 2 (1-2), P<0.001] than the MLS group. The length of hospital stay was similar in the two groups [5(4-6) vs. 5(4-5), P=0.599]. Following surgery, 38.5% of the TU-LESS patients and 41% of the MLS patients got adjuvant therapy (P=0.744). The median follow-up time for TU-LESS and MLS cohorts was 45 months (range: 20-66) and 43 months (range: 18-66), respectively. One TU-LESS patient and one MLS patient died following recurrence. The 4-year overall survival was similar in both groups (98.3% vs. 98.5%, P=0.875).

Conclusion

TU-LESS is a feasible and safe option with comparable perioperative outcomes and survival of MLS in endometrial cancer. With the growing acceptance of sentinel lymph node biopsy, TU-LESS of endometrial cancer may be a viable option for patients and surgeons.

ACR Appropriateness Criteria® Hernia

Abdominopelvic hernias are common clinical entities composed of a wide variety of congenital, traumatic, and iatrogenic etiologies. Any weakness in the body wall may result in hernia of cavity contents with concomitant risks of morbidity and mortality. Presentations may be specific, palpable body wall mass/bulge, or vague, nonspecific pain through bowel obstruction. This document focuses on initial imaging of the adult population with signs of symptoms prompting suspicion of abdominopelvic hernia. Imaging of the abdomen and pelvis to evaluate defects is essential for prompt diagnosis and treatment. Often CT and ultrasound are the first-line modalities to quickly evaluate the abdomen and pelvis, providing for accurate diagnoses and management of patients. MRI protocols may be useful as first-line imaging studies, especially in patients with orthopedic instrumentation. Although often performed, abdominal radiographs and fluorographic procedures may provide indirect evidence of hernias but are usually not indicated for initial diagnosis of hernia. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Evaluation of Closure Technique on Incidence of Incisional Hernia Following Single Port Laparoscopy in Gynecologic Oncology Surgery

STUDY OBJECTIVE

To evaluate incidence and risk factors for incisional hernia in women undergoing single-port laparoscopy (SPL) for gynecologic oncology indications with a standardized fascia closure (SC) technique versus historical controls (HC).

DESIGN

Retrospective cohort study.

SETTING

Single academic institution.

PATIENTS

Women who underwent SPL from 6/1/2017-12/31/2019 for gynecologic oncology indications with SC were compared to HC who underwent SPL from 1/1/2009-12/31/2015.

INTERVENTIONS

Data was collected for patient demographics, postoperative outcomes, and incisional hernia development. Univariate analysis and multivariable regression models were built for predictors of incisional hernia.

MEASUREMENTS AND MAIN RESULTS

Of 1,163 patients, 242 (20.8%) patients had SC and 921 (79.2%) patients had HC. SC cohort had lower rates of diabetes versus HC (10.3% vs. 15.3%; p = .049) but no differences in hypertension (36.8% vs. 43.0% p = .081) and obesity (42.6% vs. 36.9%, p = .11). 1,123 (96.6%) patients did not undergo conversion to multi-port laparoscopy or laparotomy, of whom 7.2% (n=81) of patients developed an incisional hernia; there was no difference in incisional hernia development for SC with SPL (n= 237) versus HC with SPL (n= 886) (9.7% vs. 6.5%, p = .095). On multivariable analysis, increased BMI (OR 1.06; 95% CI 1.03-1.09, p < .001) and diabetes (OR 2.41; CI 1.34-4.32, p = .003) were associated with incisional hernia, but age (OR 1.00; CI .98-1.02, p = .92), length of surgery (OR 1.00; CI 1.00-1.01, p = .62), and hypertension (OR .89; CI .52-1.53, p = .68) were not. Patients with prior abdominal surgeries (OR 1.92; CI 1.14-3.26, p = .015) and hand-assist surgery (OR 3.17; CI 1.48-6.80, p = .003) were significantly associated with incisional hernia.

CONCLUSION

Implementation of a SC protocol did not decrease rate of incisional hernia versus HC during SPL. Risk of incisional hernia must be considered for SPL planning in patients with complex medical comorbidities and prior abdominal surgery.

Long-term follow-up of the incisional hernia rate after single-incision laparoscopic cholecystectomy: a prospective observational study

PURPOSE

To evaluate the long-term occurrence rate of incisional hernias following single-incision laparoscopic cholecystectomy (SILC).

BACKGROUND

Since the 90 s, SILC has emerged as a less invasive alternative to standard laparoscopic cholecystectomy in selected patients. But concerns over port-incisional hernias have not been addressed.

METHODS

Between February 2009 and February 2011, 142 patients referred for gallstones who agreed to undergo SILC were included in a monocenter prospective observational study. All of the procedures were carried out using a single-port access technique. The occurrence rates of incisional hernias were analyzed with the Kaplan-Meier actuarial method. Statistical significance was set at p < .05.

RESULTS

A total of 142 patients with gallbladder pathology were included in the study; 138 of them underwent SILC and 4 were converted to standard multiport cholecystectomy. Twelve patients (8%) were found to have developed a port-site incisional hernia (PSH) by physical examination or by imaging. The Kaplan-Meier curve showed that the rate of PSH development was 83% in the first 2 years after surgery. After 2 years, this risk becomes quite low.

CONCLUSIONS

Our results indicate that the SILC procedure is a safe option for treatment of benign gallbladder diseases for selected patients, albeit with a high incisional hernia rate.

Risk factors of incisional hernia after single-incision cholecystectomy and safety of barbed suture material for wound closurewound closure

Purpose

Single-incision cholecystectomy is a surgical method that offers comparable results to conventional laparoscopic cholecystectomy. However, a high risk of postoperative incisional hernia is an issue in single-incision cholecystectomy. This study evaluated the risk factors and incidences of incisional hernia after single-incision cholecystectomy and the advantage issue of using barbed suture material during wound closures.

Methods

A total of 1,111 patients underwent laparoscopic or robotic single-incision cholecystectomy between March 2014 and February 2020 at our institution at CHA Bundang Medical Center. During this period, there were 693 patients who underwent wound closure with monofilament suture material (Monosyn 2-0; B. Braun) and the other 418 patients used barbed suture material (Stratafix 2-0; Ethicon).

Results

The two patient groups were comparable in age, body mass index, and diagnosis. The total incidence of incisional hernia after single-incision cholecystectomy was 0.5% (five cases). All patients who developed incisional hernia were in the monofilament suture material group (0.7% vs. 0%, p = 0.021). The influence of predictive and possible risk factors on incisional hernia rate was analyzed. Among these factors, only old age was an independent predictive risk factor of incisional hernia.

Conclusion

Our study showed a low incidence of incisional hernia, all of which occurred in the monofilament suture material group. If technically appropriate, single-incision cholecystectomy does not appear to present a high incidence of hernia. Barbed suture material can be safely applied in wound closure showing comparable incisional hernia incidence to monofilament suture material.

Comparison of short- and long-term postoperative occurrences after robotic single-incision cholecystectomy versus multiport laparoscopic cholecystectomy

BACKGROUND

Long-term outcomes of SIRC are not well established. Furthermore, SIRC is only now being considered more frequently for patients with independent risk factors for PSH, such as obesity. As such, the paucity of data on longer-term post-surgical outcomes of SIRC is particularly notable as it pertains to obese patients.

METHODS

All patients undergoing cholecystectomy performed by two surgeons at our institution from 2008-2018 were reviewed. Our inclusion criteria were patients who underwent SIRC or multiport laparoscopic cholecystectomy (MPLC) and had at least one month of postoperative follow-up. Patients who underwent additional procedures at the time of cholecystectomy were excluded. Our outcomes of interest were the 30-day POC rate and the long-term PSH rate. Analysis was conducted on an intention-to-treat basis, using logistic regression analysis for POC and time-to-event analysis for PSH.

RESULTS

We examined 584 patients who underwent either SIRC (51%) or MPLC (49%). Of the 296 patients who underwent SIRC, 15 (5%) developed a POC and 23 (8%) developed a PSH. Of the 288 patients who underwent MPLC, 11 (4%) developed a POC, and 28 (10%) developed a PSH. Procedure group and obesity was not associated with the risk of POC (p = 0.29, p = 0.21, respectively). Procedure group was not associated with an increased risk of PSH (p = 0.29). Obese patients, however, were 1.94 times more likely to develop PSH compared to non-obese patients overall (p = 0.02).

CONCLUSIONS

There is no statistically significant difference in POC and PSH rate following SIRC when compared with MPLC in patients in the same BMI group. Male gender and prior abdominal surgery are risk factors for POC, while advancing age and obesity are risk factors for PSH.

Long-term outcomes of single-incision versus multiport laparoscopic colectomy for colon cancer: results of a propensity score-based analysis

BACKGROUND

Long-term outcomes of single-incision laparoscopic colectomy (SILC) for colon cancer (CC), as practiced in real-world settings, especially in relation to disease stage, have not been established. We examined, retrospectively, both short- and long-term outcomes of SILC versus those of multiport laparoscopic colectomy (MPLC) performed for CC in a propensity-score-matched cohort.

METHODS

The study involved 263 patient pairs matched 1:1 from among 691 patients who, between January 2008 and May 2014, underwent either SILC or MPLC for a primary solitary CC at our hospital. Short-term and long-term operative outcomes were compared between the two groups.

RESULTS

Operation time was the only surgical outcome that varied significantly between the two groups (p = 0.0004). Overall 5-year cancer-specific survival (CSS) in the SILC group was 93.7 (95% CI 89.6-96.2)%, and CSS per pathological stage (I, II and III) was 98.5 (90.0-99.8)%, 96.0 (88.2-98.7)%, and 88.3 (79.6-93.6)%, respectively, whereas overall 5-year CSS in the MPLC group was 93.3 (89.4-95.9)%, and CSS per pathological stage was 100%, 95.4 (88.3-98.3)%, and 84.1 (74.1-90.8)% (p = 0.5278, 0.2679, 0.7666, and 0.9073), respectively. Overall 3-year disease-free survival (DFS) in the SILC group was 94.0 (90.2-96.4)%, and 3-year DFS per pathological stage was 98.6 (90.4-99.8)%, 90.1 (81.4-95.0)%, and 79.0 (69.4-86.2)%, respectively, whereas overall 3-year DFS in the MPLC group was 93.2 (89.4-95.7)%, and 3-year DFS per pathological disease stage was 100%, 94.5 (87.4-97.7)% and 75.5 (64.7-83.8)% (p = 0.2829, 0.7401, 0.4335 and 0.8518), respectively. Thus, oncological outcomes did not differ significantly between groups. Incisional hernia occurred in 21 (8.0%) SILC group patients and 17 (6.5%) MPLC group patients, without a significant between-group difference (p = 0.6139).

CONCLUSION

Our data indicate that perioperative and oncological outcomes of SILC performed for CC are comparable to those of MPLC performed for CC.

Low long-term incidence of incisional hernia after cholecystectomy: A systematic review with meta-analysis

BACKGROUND

Various surgical approaches are available for cholecystectomy, but their long-term outcomes, such as incidence of incisional hernia, are largely unknown. Our aim was to investigate the long-term incidence of incisional hernia after cholecystectomy for different surgical approaches.

METHODS

This systematic review and meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42020178906). Three databases were searched for original studies on long-term complications of cholecystectomy with n > 40 and follow-up ≥6 months for incisional hernia. Risk of bias within the studies was assessed using the Newcastle-Ottawa Scale and the Cochrane "risk of bias" tool. Meta-analysis of the incidence of incisional hernia after 6 and 12 months was conducted when possible.

RESULTS

We included 89 studies. Of these, 77 reported on multiport or single-incision laparoscopic cholecystectomy. Twelve studies reported on open cholecystectomy and 4 studies on robotic cholecystectomy. Weighted mean incidence proportion of incisional hernia after multi-port laparoscopic cholecystectomy was 0.3% (95% confidence interval 0-0.6) after 6 months and 0.2% after 12 months (95% confidence interval 0.1-0.3). Weighted mean incidence of incisional hernia 12 months postoperatively was 1.5% (95% confidence interval 0.4-2.6) after open cholecystectomy and 4.5% (95% confidence interval 0.4-8.6) after single-incision laparoscopic cholecystectomy. No meta-analysis could be conducted for robotic cholecystectomy, but incidences ranged from 0% to 16.7%.

CONCLUSION

We found low 1-year incidences of incisional hernia after multiport laparoscopic and open cholecystectomy, whereas risks of incisional hernia were considerably higher after single-incision laparoscopic and robotic cholecystectomy.

Incisional hernia after 2498 single-port access (SPA) gynecologic surgery over a 10-year period

The present study was conducted to report the perioperative outcomes of single-port access (SPA) laparoscopic gynecologic surgeries with focus on the incidence of postoperative incisional hernia from our cumulative data of 2498 patients. A retrospective review was performed on the women who had received SPA surgeries from 2008 to 2018. Patient characteristics and perioperative outcomes including the incidence of postoperative incisional hernia were analyzed. There were 2498 Korean patients who received SPA surgeries for various gynecologic diseases. The median age of the patients was 40.3 ± 9.2 years, and the mean body mass index (BMI) was 22.6 ± 3.2 kg/m². A total of 3 postoperative incisional hernia occurred during the study period. Two patients whose fascial layers were closed in running sutures developed hernias 6 and 8 months after their operations. One patient whose fascial layers were closed in interrupted sutures developed hernia 11 months after her operation. The incidence of postoperative incisional hernia following SPA surgery is low in Asian women whose BMI is relatively lower than other patient populations. Interrupted suture technique may reduce postoperative incisional hernia by providing a distinct visualization of fascial layers during closure. Detailed descriptions of our surgical techniques of closing the port incision are provided.

Incidence of acute postoperative robotic port-site hernias: results from a high-volume multispecialty center

Fascial closure at 8-mm robotic port sites continues to be controversial. As the use of the robotic platform increases across multiple abdominal specialties, there are more case reports describing reoperation and small bowel resection for acute port-site hernias. A retrospective review of all robotic abdominal surgeries performed from 2012 to 2019 at NYU Langone Medical Center was conducted. Patients who had a reoperation in our facility within 30 days were identified, and medical records reviewed for indications for reoperation and findings. The study included 11,566 patients, of which 82 patients (0.71%) underwent a reoperation related to the index robotic surgery within 30 days. Fifteen of 11,566 patients (0.13%) had acute port-site hernias, and 3 of these 15 patients required small bowel resection. Eleven of 15 acute port-site hernias (73%) were at 8-mm robotic port site, 2 of which required a small bowel resection. More than a third of the patients had a hernia at an 8-mm port site where a surgical drain had been placed. Considering that each robotic case, regardless of specialty, has three ports at a minimum, the true incidence of acute postoperative robotic port-site hernia is 0.032% (11/34,698), with the incidence of concomitant small bowel resection being 0.006% (2/34,698). The incidence of acute port-site hernias from 8-mm robotic ports is exceedingly low across specialties. Our results do not support routine fascial closure at 8-mm robotic port sites due to an extremely low incidence. However, drain sites require special consideration.

The First Additional Port During Single-Incision Laparoscopic Cholecystectomy

Background and Objectives:

Single-incision laparoscopic cholecystectomy (SILC) has become increasingly popular. Regarding the difficulties of SILC in acute cholecystitis, additional port insertion is sometimes required. However, appropriate locations for additional port insertion have not been well studied. In the present study, the safety and effectiveness of the first additional port insertion in the epigastric region during SILC was assessed.

Methods:

Additional port insertions were needed in 52 of 113 patients who underwent SILC for acute cholecystitis. The first port was inserted in the epigastric region and the second (if required) was inserted in the right lateral subcostal area. A drainage catheter was positioned through the epigastric port.

Results:

One additional port was inserted in 43 patients and two additional ports were inserted in 9 patients. Mean operation time was 45.0 minutes in the Pure SILC group and 83.3 minutes in Additional Port group. Mean hospital stay was 3.7 days in the Pure SILC group and 5.9 days in Additional Port group. There was no open conversion. Intra-operative (n = 5) and postoperative bile leakages (n = 2) were identified in six patients. Timing of operation after onset of symptoms was significantly greater in the group with bile duct injury than in those without bile duct injury in patients who required additional ports.

Conclusions:

The first additional port in the epigastric area during SILC for acute cholecystitis helps to complete the operation without open conversion. However, the procedure can be performed safely in selective patients with relatively short duration of symptoms.

Reduced-Port Sleeve Gastrectomy for Morbidly Obese Japanese Patients: a Retrospective Case-Matched Study

BACKGROUND

Reduced-port laparoscopic surgery remains controversial due to technical challenges that can lead to suboptimal outcomes, and data pertaining to operative and clinical outcomes of reduced-port sleeve gastrectomy (RPSG) vs. conventional laparoscopic sleeve gastrectomy (CLSG) are lacking.

AIMS

This retrospective case-matched study aimed to compare midterm (2-year) outcomes of RPSG and of CLSG.

METHODS

Patients included in the study had undergone laparoscopic bariatric surgery at our center between 2010 and 2017. Thirty-one consecutive female patients who underwent RPSG were compared to a sex-, age-, body mass index-matched group of 31 patients who underwent CLSG. Outcomes were evaluated and compared between groups.

RESULTS

Estimated blood loss volume, incidences of intraoperative and postoperative complications, and length of postoperative hospital stay did not differ significantly between the 2 groups. Operation time was significantly greater in the RPSG group than in the CLSG group (148.7 ± 22.6 vs. 120.2 ± 25.9 min, respectively; p < 0.001). Excess weight loss at 1 year was 105.9% and 109.7%, respectively (p = 0.94) and at 2 years was 101.1% and 105.3%, respectively (p = 0.64). One RPSG patient required placement of additional trocars because of bleeding from short gastric vessels, but conversion to open surgery was not required.

CONCLUSIONS

RPSG is feasible in carefully selected bariatric patients and results in midterm outcomes comparable to those observed after CLSG. Good cosmesis is a potential benefit of RPSG.

Consecutive Versus Selective Primary and Revisional Single Incision Laparoscopic Bariatric Surgery: Personal Experience in 330 Cases

BACKGROUND

This paper aims to retrospectively evaluate the feasibility, safety, and standardization for both consecutive primary and revisional SILS bariatric surgeries, and to analyze incisional hernia's prevalence, technical improvements, and limiting factors.

METHODS

A retrospective database review was undertaken involving, in Part I (Belgium), 290 consecutive SILS, including 80.68% primary bariatric surgeries, and 19.32% revisional gastric bypass, followed in Part II (Lebanon), by 40 selective primary SILS. Training for and standardization of the trans-umbilical technique was done for the operating room team, and was executed in part II.

RESULTS

The procedure of single incision was successfully completed in all of the 330 cases part I & part II. There was a need for additional salvage for one or two trocars in respectively 3.1% and 2.75% of the cases. There were no deaths or conversions in either group. Early complications included one medically healed fistula after revisional GB, and two secondary gastric and intestinal perforation requiring reoperations. Late surgical complications were: "3 patients (1.03%) in Part I and 2 (5%) in Part II suffered occlusions, requiring laparoscopic mesenteric defect's closure on an internal herniation." Twelve patients (4.1%) from part I and 5 (12.5%) in part II suffered an incisional hernia.

CONCLUSION

Selective SILS, when standardized, tends to be superior to consecutive SILS in terms of overall morbidity, operative time, and need for additional salvage trocars. Cost effectiveness and higher midterm rate of umbilical port site incisional hernia should be weighed against the beneficial cosmetic effect for the patient.

Management of Incidental Hernia Discovered During Abdominal Contouring in Post-Bariatric Surgery Patients

PURPOSE

An increase in bariatric surgery has led to a rise in postbariatric contouring procedures. Despite a comprehensive preoperative assessment, body habitus in these patients may significantly limit the abdominal exam. Abdominal contouring procedures typically elevate large portions of the skin and fat off the abdominal wall, and unexpected hernia may be discovered intraoperatively. No study to date has characterized such hernia discovery at the time of body contouring surgery. We reviewed our experience of management of incidental hernia found during abdominoplasty or panniculectomy after laparoscopic bariatric surgery.

METHODS

Records of all post-bariatric surgery patients undergoing abdominal contouring procedures between 2007 and 2017 were reviewed to identify patients with incidental hernias discovered intraoperatively. These patients were further examined by reviewing operative details, patient-specific factors, and outcomes.

RESULTS

Six hundred eighty-one post-bariatric surgery patients underwent abdominal body contouring procedures with incidental ventral hernia discovered in 36 patients (5.3% [45 hernias]). At the time of plastic surgery, average age was 49 years (range, 25-64 years), and body mass index was 30.7 kg/m (range 25-43 kg/m). Of 36 patients with incidental hernia, 26 patients (72.2%) had a single hernia, and the remainder had multiple (27.8%). Mean hernia size was 4.1 cm (range, 0.25-24 cm). Most hernias were located paraumbilical/umbilical (46.7%) or epigastric (37.8%). Ninety-eight percent of hernias were repaired primarily (n = 44) by the plastic surgeon, and in 1 case (2%), mesh repair was performed by a consulting general surgeon. Average follow-up was 1.9 ± 0.3 years. Only 1 patient (2.8%) developed hernia recurrence after 48 months. Other postoperative complications included superficial wound healing problems (19.4%), seroma (16.7%), suture abscess (5.6%), and cellulitis that resolved with antibiotics (5.6%).

CONCLUSIONS

This is the first study to characterize incidental hernia discovered at the time of body contouring in the post-bariatric surgery patient. The body contouring surgeon should be aware of this common finding. Hernias typically discovered during panniculectomy or abdominoplasty arise in umbilical or epigastric regions, likely from prior laparoscopic port sites, and can be safely repaired by the plastic surgeon with low overall complication rates.

True single-port cholecystectomy with ICG cholangiography through a single 15-mm trocar using the new surgical platform "symphonX": first human case study with a commercially available device

BACKGROUND

Minimally invasive single-port surgery is often associated with large incisions up to 2-3 cm, complicated handling due to the lack of triangulation, and instrument crossing. Aim of this prospective study was to perform true single-port surgery (cholecystectomy) without the use of assisting trocars using a new surgical platform that allows for triangulation incorporating robotic features, and to measure the perioperative outcome and cosmetic results.

METHODS

As the first European site after FDA and CE-mark approval, the new device has been introduced to our academic center. In patients with cholecystitis and cholecystolithiasis, the operation was performed through only one 15-mm trocar. For patients safety, intraoperative cholangiography using intravenous ICG and a standard Stryker 1588 system was routinely performed.

RESULTS

Symphonx was used in n = 12 patients for abdominal surgery (6 females, mean age 42.5 [30-77], mean BMI 26.2 [19.3-38.9]. A total of 8 patients underwent surgery using no additional ports besides the 15-mm trocar; in the remaining patients, one assisting instrument (3-5 mm) was used. Mean OR time was 107 [72-221] minutes. The postoperative course was uneventful in 11 patients; in one patient, a seroma at the surgical site required interventional drainage 1 month postoperatively. No intraoperative complications occurred.

CONCLUSION

This is the first human case series using the commercially available symphonX platform for abdominal laparoscopic surgery and the first series using the system without assisting instruments. Laparoscopic cholecystectomy in patients with cholecystitis and cholecystolithiasis using the symphonX platform through only one 15-mm trocar is feasible, safe, and more cost-efficient compared to robotic platforms.

Updated outcomes of laparoscopic versus open umbilical hernia repair in patients with obesity based on a National Surgical Quality Improvement Program review

BACKGROUND

Currently, there's not a well-accepted optimal approach for umbilical hernia repair in patients with obesity when comparing laparoscopic umbilical hernia repair (LUHR) versus open umbilical hernia repair (OUHR).

OBJECTIVE

The objective of this study was to evaluate if there's a difference in postoperative complications after LUHR versus OUHR with the goal of indicating an optimal approach.

METHODS

A retrospective analysis was completed using the 2016 National Surgical Quality Improvement Program (NSQIP) database to identify patients with obesity (Body Mass Index (BMI) ≥ 30 kg/m²) who underwent LUHR or OUHR. Patients were divided into OUHR and LUHR groups, and post-operative outcomes were compared, focusing on wound complications.

RESULTS

A total of 12,026 patients with obesity who underwent umbilical hernia repair were identified; 9695 underwent OUHR, while 2331 underwent LUHR. The LUHR group was found to have a statistically significant higher BMI (37.5 kg/m² vs. 36.1 kg/m²; p < 0.01) and higher incidence of diabetes mellitus requiring therapy (18.4% vs. 15.8%; p < 0.01), hypertension (47.5% vs. 43.8%; p < 0.01), and current smoker status (18.6% vs. 16.5%; p < 0.02). Superficial surgical site infection (SSI) was significantly higher in the OUHR group (1.5% vs. 0.9%; p < 0.03), and there was a trend towards higher deep SSI in the OUHR group (0.3% vs. 0.5%; p = 0.147). There was no difference in organ space SSI, wound disruption, or return to OR. On logistic regression, composite SSI rate (defined as superficial, deep, and organ space SSIs) was significantly increased in the OUHR group (p < 0.01). Predictive factors significantly associated with increased morbidity included female gender and higher BMI.

CONCLUSIONS

In patients with obesity, even though the LUHR group had an overall higher BMI and higher rates of diabetes, hypertension, and current smoking status, they experienced decreased post-operative wound complications compared to the OUHR group.

Single incision laparoscopic fundoplication: A systematic review of the literature

BACKGROUND

Fundoplication, was first introduced as a surgical treatment method of gastroesophageal reflux disease. Consequently, several modifications of this method have been described, whereas laparoscopic fundoplication was recently introduced. Although single incision (SI) fundoplication was considered as an alternative to the conventional laparoscopic approach, several studies reported an increased operation duration, and high rates of multiport conversion and incisional hernia.

AIM

To provide a current overview of the technical variations and the postoperative outcomes of patients submitted to SI fundoplication.

METHODS

The present systematic review of the literature was designed and conducted on the basis of the PRISMA guidelines. A systematic screening of the electronic scholar databases (Medline, Scopus and Web of Science) was performed.

RESULTS

Literature search resulted in the identification of 19 studies. Overall, 266, 137 and 110 SI Nissen, Dor and Toupet fundoplications were reported, respectively. In the majority of the trials, standard laparoscopic instruments were used. The left liver lobe was displayed through the use of forceps, graspers, retractors, drains or even glue. Both intra-corporeal and extracorporeal suturing was described. Mean operative time was 136.3 min. Overall complication rate was 5.2% and the rate of incisional hernia was 0.9%. No mortality was reported.

CONCLUSION

Due to the methodological heterogeneity and the lack of high quality studies comparing multi to single access techniques and the several variations, we conclude that further well designed studies are necessary, in order to evaluate the role of SI fundoplication.

Long-term follow-up after single-incision laparoscopic surgery

BACKGROUND

Single-incision laparoscopic surgery (SILS) is growing in popularity. The increased diameter of the umbilical incision might raise questions about the possibility of a greater risk of postoperative incisional hernia in comparison to conventional laparoscopy. This study aims to disclose the frequency of incisional hernia after SILS in long-term follow-up as well as to reveal the factors predisposing patients to this feared complication.

METHODS

The patient collective consists of cholecystectomy and appendectomy patients, who were operated on using SILS technique. Follow-up was achieved through letter correspondence, telephone interview, and clinical examination. Effects of demographic variables and operative parameters including age, sex, BMI, ASA score, duration of surgery, pre-existing hernia as well as postoperative incidence of incisional hernia were investigated using univariate and multivariate analyses.

RESULTS

A total of 286 cases with complete follow-up were included in the analyses. Mean follow-up duration was 58.4 months. 192 patients (67.1%) underwent cholecystectomy; 94 (32.9%) had an appendectomy. The study collective consisted of 218 women (76.2%) and 68 men (23.8%). Mean age at the date of the operation was 38.5 (median 36, range 13-74). In 5 cases (1.7%), the surgical approach was converted into conventional laparoscopy. Intraoperative complication rate was 0.3% and postoperative complication rate was 5.9%. 7 patients (2.4%) developed an incisional hernia. Obese patients had an incisional hernia incidence of 10.9%. 3 out of 19 patients (15.8%) with a pre-existing umbilical hernia developed an incisional hernia during follow-up. Obesity and pre-existing umbilical hernia proved to have a significant association with incisional hernia incidence in univariate and multivariate analyses. Sex, age, procedure (appendectomy vs cholecystectomy), presence of acute inflammation, and duration of surgery did not show a statistically significant association with incisional hernia.

CONCLUSION

Detection of incisional hernia necessitates a long follow-up duration. Obesity and pre-existing umbilical hernia are associated with a higher incidence of this complication. Following a careful patient selection, SILS offers a safe approach for cholecystectomy and appendectomy procedures.

Perforated appendicitis in the setting of a massive ventral hernia, morbid obesity, and multiple severe comorbidities: challenges in acute management

Case summary: A 57-year-old woman with morbid obesity (body mass index [BMI] of 43), systemic lupus on steroids, type 2 insulin-dependent diabetes, peripheral vascular disease, unprovoked pulmonary embolism on rivaroxaban, and hypertension presented with 3 days of worsening abdominal pain and nausea. She had an extensive surgical history including a cesarean section, multiple laparotomies for small bowel obstructions (one complicated by bowel perforation requiring resection), and a double-barrelled ileostomy, which had been since reversed. As a result, she had a massive incisional hernia (figure 1). On presentation she was afebrile but tachycardic at 110 beats per minute. Physical examination revealed tenderness to deep palpation in the right upper and lower quadrants. CT demonstrated an 11 mm appendix with an appendicolith outside the hernia sac abutting the right kidney, discontinuity of the appendix tip, free fluid, and associated stranding in the subhepatic region (figure 2A). She was admitted to the surgical floor for a trial of conservative management with ancef and flagyl. On day 3, her pain worsened, her white cell count remained stable at 12 x10⁹/L, her temperature was 37.8°C, she was not tachycardic, and a repeat CT showed a 15 mm perforated appendix with increased periappendiceal stranding and an associated small volume of free fluid. There was no phlegmon or organized abscess (figure 2B).Figure 1Patient's abdomen demonstrating midline laparotomy incisional scar, previous ileostomy scar, and massive ventral hernia.Figure 2Abdominal CT showing increased stranding centered around the appendix, with discontinuity of the wall of the appendix tip and free fluid within the abdomen and pelvis.

Clinical impact of single-incision laparoscopic right hemicolectomy with intracorporeal resection for advanced colon cancer: propensity score matching analysis

BACKGROUND

Laparoscopic right hemicolectomy has become an acceptable treatment for right-sided colon cancer. Most centers use multiport laparoscopic right hemicolectomy extracorporeally (MRHE), whereas single-incision laparoscopic right hemicolectomy intracorporeally (SRHI) remains controversial. The aim of this study was to compare these two techniques using propensity score matching analysis.

METHODS

We analyzed the data from 111 patients who underwent laparoscopic right hemicolectomy between December 2015 and December 2016. The propensity score was calculated according to age, gender, body mass index, the American Society of Anesthesiologists score, previous abdominal surgery, and D3 lymph node dissection. Postoperative pain was evaluated using a visual analogue scale (VAS) and postoperative analgesic use was an outcome measure.

RESULTS

The length of skin incision in SRHI was significantly shorter than in MRHE [3 (3.5-6) versus 4 (3-6) cm, respectively; P = 0.007]. The VAS score on day 1 and day 2 after surgery was significantly less in SRHI than in MRHE [30 (10-50) versus 50 (20-69) on day 1, P = 0.037; 10 (0-50) versus 30 (0-70) on day 2, P = 0.029]. Significantly fewer patients required analgesia after SRHI on day 1 and day 2 after surgery [1 (0-3) versus 2 (0-4) on day 1, P = 0.024; 1 (0-2) versus 1 (0-4) on day 2, P = 0.035]. There were no significant differences in operative time, intraoperative blood loss, number of lymph nodes removed, and postoperative course between groups.

CONCLUSIONS

SRHI appears to be safe and technically feasible. Moreover, SRHI reduces the length of the skin incision and postoperative pain compared with MRHE.

Suprapubic single-port approach for complicated diverticulitis

BACKGROUND

Laparoscopic sigmoidectomy is the gold standard for elective surgical treatment of diverticulitis. A periumbilical single-port technique reduces the size of the access wound, usually to 3-4 cm. However, in the presence of large phlegmon or fistulae, the risk of conversion is higher and the extraction site might be enlarged. A suprapubic Pfannenstiel incision reduces the risk of incisional hernia compared to umbilical access and might provide the possibility to perform sigmoidectomy with a hybrid technique. The aim of the present study was to investigate the feasibility of laparoscopic sigmoidectomy through a single suprapubic transverse access for large diverticular phlegmon.

METHODS

Consecutive patients with a diverticular inflammatory mass ≥ 5 cm, with or without sigmoid-vesical fistula, were considered candidates for laparoscopic sigmoidectomy through a 5-cm single-port suprapubic (SPSP) access, extended (if required) to match the size of the inflammatory mass.

RESULTS

Twenty patients underwent SPSP sigmoidectomy at our institution in April 2014-April 2017. All procedures were completed by SPSP access, with no intraoperative complications or need for additional trocar placement. Eight patients had a sigmoid-vesical fistula (bladder sutured in three patients). The splenic flexure was mobilized in nine patients. Median operative time was 178 min and median hospital stay was 5.5 days (iqr 4-6). Postoperative complications occurred in four patients and included one subcutaneous hematoma, one urinary tract infection, and two superficial wound infections. After a median follow-up time of 25 months (interquartile range 15-38), all patients experienced complete resolution of symptoms, with no incisional hernias reported.

CONCLUSIONS

SPSP sigmoidectomy for diverticulitis is feasible and effective, minimizing the size of the access wound and avoiding increased risk of hernia. This approach might be especially valuable for the management of large diverticular phlegmon and sigmoid-vesical fistula.

Conventional versus Single Port Laparoscopy for the Surgical Treatment of Ectopic Pregnancy: A Meta-Analysis

BACKGROUND/AIMS

A new minimally invasive laparoscopic approach for ectopic pregnancy, the laparo-endoscopic single site surgery (LESS), has recently been introduced. The aim of this study is to compare the surgical outcome of this approach with conventional laparoscopy for ectopic pregnancy.

METHOD

A review following the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement was performed. Electronic databases PubMed, MEDLINE, and Scopus were searched in December 2017 by searching the terms "single port laparoscopy" or "laparoendoscopic single site-surgery" or "single site laparoscopy" or "single-incision laparoscopic surgery" and "ectopic pregnancy." Studies comparing the 2 techniques and reporting surgical outcome were selected. Endpoints included comparison of length of operative time (OT), hemoglobin drop, length of hospitalization, number of patients requiring packed red blood cells (PRBC) transfusion, intra- and post-operative complication rates between patients undergoing conventional laparoscopy and those undergoing LESS.

RESULTS

A total of 56 studies were retrieved of which 5 studies including 460 patients met selection criteria. No differences were found between conventional laparoscopy and LESS with regards to length of OT time (even after stratification for presence of hemoperitoneum and/or adhesions), length of hospitalization, mean hemoglobin drop, number of patients requiring transfusions of PRBC, and intra- and post-operative complications.

CONCLUSION

The management of ectopic pregnancies with LESS does not seem to be superior to conventional laparoscopy.

Laparoendoscopic Single-Site Bariatric Surgery: A Review of Single-Port Laparoscopic and Endoscopic Bariatric Treatments

Bariatric surgery is an established and effective treatment, not only to combat morbid obesity, but also to address associated metabolic comorbidities. At this time, the cutoff for bariatric or metabolic surgery in terms of body mass index (BMI) is decreasing, making it more feasible for certain individuals to consider minimally invasive surgical options. Innovations in the technique have led to the application of laparoendoscopic single-site surgery (LESS) in the field of bariatrics, which uses a single or no incision in the performance of weight-reducing surgery. To date, there is no consensus regarding patient selection though most candidates for single-port bariatric surgery are female. Some doctors suggest that single-port bariatric surgery may not be recommended in patients with BMI of more than 50 kg/m², height of more than 180 cm, and xiphoid–umbilicus distance of more than 20 cm. Sleeve gastrectomy (SG) is now the most widely performed bariatric surgery worldwide and single-port SG (SPSG) is already established as a routine procedure in various institutions. Current evidence shows that SPSG is less painful and demonstrates higher rates of patient satisfaction regarding the wound. SPSG is feasible and is recommendable in patients who meet certain criteria. Furthermore, endoscopic treatment modalities such as intragastric balloons and endoluminal malabsorptive devices are being developed to bridge the gap between medical and surgical treatments. Nevertheless, there is still insufficient evidence to prove the superiority of LESS bariatric surgery over conventional laparoscopic surgery. Large, well-designed prospective analyses are needed to determine the criteria for selecting patients suitable to undergo LESS bariatric surgery and to predict the procedure’s role in the growth of bariatric surgery.

Single-port laparoscopy in gynecologic oncology: seven years of experience at a single institution

BACKGROUND

Single-port laparoscopy has gained popularity within minimally invasive gynecologic surgery for its feasibility, cosmetic outcomes, and safety. However, within gynecologic oncology, there are limited data regarding short-term adverse outcomes and long-term hernia risk in patients undergoing single-port laparoscopic surgery.

OBJECTIVE

The objective of the study was to describe short-term outcomes and hernia rates in patients after single-port laparoscopy in a gynecologic oncology practice.

STUDY DESIGN

A retrospective, single-institution study was performed for patients who underwent single-port laparoscopy from 2009 to 2015. A univariate analysis was performed with χ² tests and Student t tests; Kaplan-Meier and Cox proportional hazards determined time to hernia development.

RESULTS

A total of 898 patients underwent 908 surgeries with a median follow-up of 37.2 months. The mean age and body mass index were 55.7 years and 29.6 kg/m², respectively. The majority were white (87.9%) and American Society of Anesthesiologists class II/III (95.5%). The majority of patients underwent surgery for adnexal masses (36.9%) and endometrial hyperplasia/cancer (37.3%). Most women underwent hysterectomy (62.7%) and removal of 1 or both fallopian tubes and/or ovaries (86%). Rate of adverse outcomes within 30 days, including reoperation (0.1%), intraoperative injury (1.4%), intensive care unit admission (0.4%), venous thromboembolism (0.3%), and blood transfusion, were low (0.8%). The rate of urinary tract infection was 2.8%; higher body mass index (P = .02), longer operative time (P = .02), smoking (P = .01), hysterectomy (P = .01), and cystoscopy (P = .02) increased the risk. The rate of incisional cellulitis was 3.5%. Increased estimated blood loss (P = .03) and endometrial cancer (P = .02) were independent predictors of incisional cellulitis. The rate for surgical readmissions was 3.4%; higher estimated blood loss (P = .03), longer operative time (P = .02), chemotherapy alone (P = .03), and combined chemotherapy and radiation (P < .05) increased risk. The rate of incisional hernia rate was 5.5% (n = 50) with a mean occurrence at 570.2 ± 553.3 days. Higher American Society of Anesthesiologists class (P = .04), diabetes (P < .001), hypertension (P = .043), increasing age (P = .017; hazard ratio [HR], 1.03), and body mass index (P < .001; HR, 1.08) were independent predictors for incisional hernia development. Previous abdominal surgeries (P = .24) and hand assist (P = .64) were not associated with increased risk for incisional hernia. Patients with American Society of Anesthesiologists class III/IV had a 3 year hernia rate of 12.8% (HR, 1.81). Patients with diabetes mellitus had a 3 year hernia rate of 23.0% (HR, 3.60).

CONCLUSION

In this large cohort of patients undergoing single-port laparoscopy, the incidence of short-term adverse outcomes is low. While the rate of incisional hernia was 5.5%, incidence reached 23.0% at 3 years in high-risk groups. Previous studies with short follow-up duration may underestimate the risk of hernia, especially in patients with significant comorbidities.

Single Port and Conventional Laparoscopy in Colorectal Surgery: Comparison of Two Techniques

BACKGROUND

Single-incision laparoscopic surgery (SILS) was introduced to further the enhanced outcome of conventional multiport laparoscopy (CML). We compared their short- and long-term outcomes in colorectal surgery.

MATERIALS AND METHODS

Retrospective review of patients who underwent elective laparoscopic colorectal surgery during 3-year period. Patients' data, surgery outcomes, and oncological results were compared.

RESULTS

Sixty-one patients (33 male, 28 female), mean age 67.4 years, underwent laparoscopic colonic resections: 28 SILS and 33 CML. Twenty-three (37.7%) patients had previous abdominal surgery. There were 19 (31.2%) right, 9 (14.7%) left, and 2 (3.3%) total colectomies, 16 (26.2%) sigmoidectomies, 13 (21.3%) anterior and 2 (3.3%) abdominoperineal resections. Colonic malignancy was a main indication for the surgery in 51 (83.6%) patients. Mean surgery time and postoperative stay were 92.0 minutes and 9 days, respectively. Pathological examination revealed stage I colon cancer in 16 (32%), stage II in 22 (44%), stage III in 10 (20%), and stage IV in 2 (4%) patients. Mean number of retrieved lymph nodes was 19 ± 13.5. No differences were found between groups in demographic data, type of surgery, surgery time and hospital stay, pathological results and tumor staging, and disease-free and overall survivals. In the SILS group, placement of additional trocar was required in 7 (25%) and conversion in 3 (10.7%) cases compared with 1 (3%) case of conversion to formal laparotomy in the CML group. Overall postoperative morbidity was 16.4%. There was no mortality in both the groups. During the study period, 3 patients from the CML group had cancer recurrence.

CONCLUSIONS

SILS is a feasible and safe technique compared with CML in terms of surgical and oncological outcomes.

Solo Single-Incision Laparoscopic Resectional Roux-en-Y Gastric Bypass for Morbid Obesity with Metabolic Syndrome

With the advancement of laparoscopic devices and surgical technology, the era of minimal invasive surgery has progressed to reduced-port surgery, and finally to single-incision laparoscopic surgery (SILS). Several reports show successful application of SILS to various types of bariatric surgery. Oftentimes, this requires a skilled and experienced scopist to perform the procedure. To overcome the technical difficulties of single-incision Roux-en-Y gastric bypass, a manual scope holder was used instead of an assistant scopist, greatly stabilizing the field of view. This allows the surgery to be performed at any time without being influenced by the need of a highly experienced scopist. In this report, we describe in detail the world's first solo single-incision laparoscopic resectional Roux-en-Y gastric bypass.

Postoperative Outcomes after Single-port Laparoscopic Removal of Adnexal Masses in Patients Referred to Gynecologic Oncology at a Large Academic Center

STUDY OBJECTIVE

To report surgical and pathologic outcomes after single-port laparoscopy (SPL) for adnexal masses in patients referred to a gynecologic oncology practice at a single academic institution.

DESIGN

A retrospective analysis (Canadian Task Force Classification II.2).

SETTING

A single academic institution with multiple hospital centers.

PATIENTS

Women who underwent at least 1 single-port laparoscopic surgery for the treatment of an adnexal mass from 2009 to 2015 after referral to a gynecologic oncology practice.

INTERVENTION

Data were collected on the surgical procedure, patient demographic variables, 30-day surgical outcomes, and hernia development.

MEASUREMENTS AND MAIN RESULTS

Three hundred twenty-five surgeries were performed in 322 patients with a median follow-up of 42.7 months. The median age was 54.5 years, and the median body mass index was 28.1 kg/m². All patients underwent unilateral or bilateral salpingectomy or oophorectomy with or without hysterectomy (26.5%). The median operative time was 90.0 minutes. The median mass dimension was 6.4 cm with 17.9% (n = 60) greater than 10 cm. Masses were categorized as simple (11.4%) and complex (69.5%). Although the majority (87.4%) of masses were benign, 7.4% were malignant, and 5.2% were borderline. Benign masses were physiologic (16.6%), serous cystadenomas (19.1%), mucinous cystadenomas (6.8%), endometriomas (12.3%), myomas (12.3%), and mature teratomas (9.2%). In malignant cases (7.4%), serous carcinoma was the most frequent histology (58.3%). The rate of adverse outcomes within 30 days, including reoperation (0.0%), intraoperative injury (1.5%), venous thromboembolism (0.3%), and transfusion (0.6%), was low. The development of incisional cellulitis was 4.6%. The rate of incisional hernia was 4.0%, with a median occurrence of 18.3 months. Diabetes mellitus (p = .03) and obesity (p = .04) were significant predictors for a hernia, but mass complexity (p = .28), American Society of Anesthesiologists class (p = .83), and smoking (p = .82) were not.

CONCLUSION

In patients undergoing SPL for the removal of adnexal masses in a gynecologic oncology practice, the rate of benign disease is high. SPL removal of adnexal masses is feasible and safe with favorable surgical outcomes, rare short-term adverse outcomes, and a low incisional hernia rate.

Comparison of single-incision and conventional laparoscopic surgery for benign adnexal masses

BACKGROUND

Our aim was to compare single incision and conventional laparoscopic surgeries performed for benign adnexal masses with regard to their intraoperative characteristics and postoperative pain levels.

MATERIAL AND METHODS

The main outcome measures were laparoscopic entry time, total operation time, amount of bleeding, intraoperative complications, post-operative pain scores, additional analgesic requirements, and length of hospital stay.

RESULTS

A total of 71 women, 39 in the conventional laparoscopy group and 32 in the SILS group, participated in the study. Demographic findings did not differ between the two groups. Similarly, rates of intraoperative complications, rates of conversion to laparotomy, pre- and postoperative hematocrit levels were not significantly different between the groups. Laparoscopic entry time was shorter in the SILS group (10.4 ± 5.9 min. vs. 5.28 ± 1.7 min.). However, total operation time was similar in the two groups. The groups did not show significant differences regarding additional analgesic requirements, or postoperative pain scores after 24 h. However, pain scores in the recovery room and after six and 12 h were lower in the SILS group.

CONCLUSION

SILS seems to be effective and safe for the treatment of benign adnexal masses. SILS appears to be advantageous regarding postoperative pain especially in the early period.

Single-incision laparoscopy surgery: a systematic review

Background

Laparoscopic surgery is a modern surgical technique in which operations are performed far from their location through small incisions elsewhere in the body.

Objective

This systematic review is aimed to overview single-incision laparoscopy surgery.

Methods

This systematic review was carried out by searching studies in PubMed, Medline, Web of Science, and IranMedex databases. The initial search strategy identified about 87 references. In this study, 54 studies were accepted for further screening and met all our inclusion criteria [in English, full text, therapeutic effects of single-incision laparoscopy surgery and dated mainly from the year 1990 to 2016]. The search terms were “single-incision,” “surgery,” and “laparoscopy.”

Results

Single-incision laparoscopy surgery is widely used for surgical operations in cholecystectomy, sleeve gastrectomy, cholecystoduodenostomy, hepatobiliary disease, colon cancer, obesity, appendectomy, liver surgery, rectosigmoid cancer, vaginal hysterectomy, vaginoplasty, colorectal lung metastases, pyloroplasty, endoscopic surgery, hernia repair, nephrectomy, rectal cancer, colectomy and uterus-preserving repair, bile duct exploration, ileo-ileal resection, lymphadenectomy, incarcerated inguinal hernia, anastomosis, congenital anomaly, colectomy for cancer.

Conclusion

Based on the findings, single-incision laparoscopy surgery is a scarless surgery with minimal access. Although it possesses lots of benefits, including less incisional pain and scars, cosmesis, and the ability to convert to standard multiport laparoscopic surgery, it has some disadvantages, for example, less freedom of movement, fewer number of ports that can be used, and the proximity of the instruments to each other during the operation.
