Single-incision laparoscopy surgery: a systematic review

Feasibility and preliminary experience of single-incision plus one-port laparoscopic total gastrectomy with Overlap esophagojejunostomy for gastric cancer: A study of 10 cases

Background

This study aimed to explore the feasibility and safety of single-incision plus one-port laparoscopic total gastrectomy (SITG + 1) with Overlap esophagojejunostomy (SITG + 1-Overlap) and to share preliminary experiences.

Methods

This retrospective study included 10 patients with gastric cancer located in the cardia or body who underwent SITG + 1-Overlap between August 2020 and October 2021.The demographics, tumor characteristics, postoperative outcomes, and short-term complications of all the enrolled patients were summarized and statistically analyzed. Data were expressed as mean ± standard deviation (SD) if they were normally distributed. Otherwise, Median (Quartile1, Quartile3) was used.

Results

In the collective perioperative data of these 10 patients who underwent radical gastrectomy, the median of the length of transumbilical incision and blood loss were 3.0 cm and 100.0 ml respectively, and the mean operation time and 385.5 ± 51.6 min. Postoperative data indicated that the gastric tube was removed on 2.0 (2.0, 3.0) days, and the timing of first feeding, activity, flatus, and defecation was 1.5 (1.0, 2.0) days, 2.0 (2.0, 2.0) days, 3.0 (2.0, 3.0) days, and 3.8 ± 0.6 days, respectively. The timing of drainage tube removal was 4.6 ± 1.0 days after operation. The duration of hospital stay was 7.5 ± 1.2 days and the VAS pain scores for the 3 days following surgery were 3.0 (2.0, 3.3), 2.0 (2.0, 3.0), and 1.5 (1.0, 2.0) respectively. The mean number of retrieved lymph nodes was 30.7 ± 13.2. Most biochemical indicators gradually normalized with the recovery of the patients after surgery. No 30-day postoperative complications were noted.

Conclusions

For the first time, our preliminary data indicate the feasibility and safety of Overlap esophagojejunostomy in SITG + 1 surgery. This modified Overlap procedure has the potential to simplify the reconstruction procedure and lower the technical challenge of SITG + 1 radical gastrectomy for cardia or upper gastric cancer in the early and advanced stages.

Hartmann’s Reversal: Controversies of a Challenging Operation

Purpose. Hartmann’s reversal is a complex operation with a high morbidity rate. Minimally invasive surgery has been used to reduce the impact of surgery on fragile patients. The aim of this comparative study is to look at the results of Hartmann’s reversal procedures with different approaches. Methods. All the patients who underwent Hartmann’s reversal were collected retrospectively (124 cases). Sixty-four patients (50.4%) had an open operation, 6 cases (5%) were treated with a conventional laparoscopic approach, 34 patients (28.1%) underwent single incision laparoscopic surgery (SILS), and 20 (16.5%) required other additional trocars. Results. SILS operations were slightly longer than the open procedures (175 min vs 150 min), with the same rate of postoperative complications and reoperations (p = 0.83 and p = 0.42), but with a shorter hospital stay (5 days p = 0.007). Age (p = 0.03), long operative time (p = 0.01), and ASA score (p = 0.05) were identified as independent factors affecting postoperative morbidity. The grade of adhesions caused a longer operative time (p = 0.001) and a higher risk of conversion $\left(p<0.001\right)$ , and short rectal stump increased the risk of protective loop ileostomy (p = 0.008). Patients with grade 2-3 of adhesions had a longer length of stay (p = 0.05). Conclusions. Minimally invasive procedures had a shorter hospital stay and did not show any increase in morbidity rate when compared with open cases. Age, longer operative time, and ASA score increased the risk of postoperative complications. Furthermore, patients with a short rectal stump had a higher chance of having a defunctioning ileostomy.

Comparison of clinical efficacy of single-incision and traditional laparoscopic surgery for colorectal cancer: A meta-analysis of randomized controlled trials and propensity-score matched studies

Background

Single-incision laparoscopy surgery (SILS) is a new laparoscopic technique that has emerged in the past decade. Whether it has advantages over conventionl laparoscopy surgery (CLS) is inconclusive. This article aimed to compare the short- and long-term outcomes of single-incision laparoscopic surgery and conventional laparoscopic surgery for colorectal cancer through high-quality literature text mining and meta-analysis.

Methods

Relevant articles were searched on the PubMed, Embase, and Cochrane Library databases from January 2012 to November 2021. All data was from randomized controlled trials (RCTs) in order to increase the confidence of the analytical results.The main outcomes were intraoperative and postoperative complications.

Results

A total of 10 RCTs were included, involving 1609 patients. The quality of the included studies was generally high. No significant difference was found between SILS and CLS in the postoperative complications, operation time, postoperative hospital stay, number of lymph nodes removed, readmission, reoperation, complication level I- II, complication level IIIa, complication level IIIb, prolonged Ileus, blood loss, infection, anastomotic leakage and operation time. The results showed that SILS group had a higher rate of intraoperative complications, but it had lower incision length and better cosmetic effects.

Conclusion

These results indicate that SILS did not have a comprehensive and obvious advantage over the CLS. On the contrary, SILS has higher intraoperative complications, which may be related to the more difficulty of SILS operation, but SILS still has better cosmetic effects, which is in line with the concept of surgical development. Therefore, the SILS needs to be selected in patients with higher cosmetic requirements and performed by more experienced surgeons.

Paratubal Cystectomy in a Pregnant Woman Using the Single-Incision Laparoscopic Surgery (SILS) Technique

Introduction

The proliferation of prenatal ultrasound has enhanced the detection of adnexal masses during pregnancy. The presentation necessitates a clear approach to investigation and treatment that balances both maternal and fetal risk. Laparoscopy is a safe approach to surgical management in the pregnant patient, and SILS may contribute to minimising perioperative complications. Case Presentation. We present the case of a 21-year-old female in her second trimester of pregnancy presenting with a large 20 cm right adnexal cyst. We proceeded with laparoscopic cystectomy via the SILS technique. There were no intraoperative complications, and she recovered well postoperatively.

Conclusion

Laparoscopic resection of adnexal lesions is safe during pregnancy and should be favoured over the open approach. SILS minimises incision sites and has potential for reduction in perioperative morbidity.

Incidence and risk factors for umbilical incisional hernia after reduced port colorectal surgery (SIL + 1 additional port)-is an umbilical midline approach really a problem?

PURPOSE

Umbilical midline incisions for single incision- or reduced port laparoscopic surgery are still discussed controversially because of a higher rate of incisional hernia compared to conventional laparoscopic techniques. The aim of this study was to evaluate incidence and risk factors for incisional hernia after reduced port colorectal surgery.

METHODS

A total 241 patients underwent elective reduced port colorectal surgery between 2014 and 2020. Follow-up was achieved through telephone interview or clinical examination. The study collective was examined using univariate and multivariate analysis.

RESULTS

A total of 150 patients with complete follow-up were included into this study. Mean follow-up time was 36 (IQR 24-50) months. The study collective consists of 77 (51.3%) female and 73 (48.7%) male patients with an average BMI of 26 kg/m² (IQR 23-28) and an average age of 61 (± 14). Indication for surgery was diverticulitis in 55 (36.6%) cases, colorectal cancer in 65 (43.3%) patients, and other benign reasons in 30 (20.0%) cases. An incisional hernia was observed 9 times (6.0%). Obesity (OR 5.8, 95% CI 1.5-23.1, p = 0.02) and pre-existent umbilical hernia (OR 161.0, 95% CI 23.1-1124.5, p < 0.01) were significant risk factors for incisional hernia in the univariate analysis. Furthermore, pre-existent hernia is shown to be a risk factor also in multivariate analysis.

CONCLUSION

We could demonstrate that reduced port colorectal surgery using an umbilical single port access is feasible and safe with a low rate of incisional hernia. Obesity and pre-existing umbilical hernia are significant risk factors for incisional hernia.

Left paraduodenal hernia treated by single-incision laparoscopic surgery: a case report

Background

Paraduodenal hernia is a rare internal hernia which accounts for only 1% of all intestinal hernias. There have been limited reported cases of paraduodenal hernia treated by laparoscopic surgery. We report a case of left paraduodenal hernia that was successfully treated by single-incision laparoscopic surgery (SILS).

Case presentation

A 17-year-old woman presented with left upper abdominal pain. An abdominal enhanced multi-detector computed tomography demonstrated encapsulated cluster of small bowel loops in the left upper quadrant which passed through the dorsal side of the inferior mesenteric vein, and showed that blood flow of the prolapsed small bowel was preserved. We preoperatively diagnosed left paraduodenal hernia without ischemia or necrosis. We performed elective SILS because she was a young actress training school student and cosmetic benefit was thought to be important. We pulled out the protruded small bowel and closed a defect with a running suture by SILS. The patient was discharged 3 days after the surgery with no complications.

Conclusions

We reported the case of left paraduodenal hernia successfully diagnosed and treated by SILS.

Foreign body perforation of the distal ileum: an unusual cause of right iliac fossa pain managed via single incision laparoscopic surgery (SILS) approach

A 61-year-old woman was seen by the emergency general surgical team with a 2-week history of right iliac fossa pain. Imaging revealed the possibility of a distal ileum perforating foreign body. Using a single incision laparoscopy surgery (SILS) approach, this diagnosis was confirmed at operation. This emerging technique meant a much smaller incision could be used than traditional exploratory laparotomy, with the benefit of less postoperative pain and a faster recovery. This case highlights an uncommon cause for abdominal pain and the importance of close liaison with radiologists and the low threshold for use of laparoscopy as a diagnostic tool. We advocate the use of SILS in the emergency setting for appropriate cases.

Single-incision retroperitoneal laparoscopic repair of superior lumbar hernia using self-fixating ProGrip mesh: A case report

•

Superior lumbar hernia is an uncommon hernia.

•

We performed single-incision retroperitoneal laparoscopic repair.

•

Self-fixating mesh without fixation is useful because of no risk of nerve injury.

Introduction

Lumbar hernia is rare and represents less than 1–2% of all abdominal hernias. There are mainly two types of lumbar hernia: superior lumbar hernia and inferior lumbar hernia.

Case presentation

A 65-year-old woman was admitted complaining of a mass in her left lumbar area. Under a diagnosis of superior lumbar hernia, single-incision laparoscopic retroperitoneal repair was performed. A single, 2-cm-long incision was made and the retroperitoneal space was dissected gradually. The hernia orifice was recognized and hernia sac was slipped from the hernia orifice. The collateral branch of subcostal nerve and iliohypogastric nerve were recognized. Laparoscopic self-fixating mesh was placed to cover the hernia orifice without mesh fixation. The patient remained well with no signs of recurrence.

Discussion

In laparoscopic lumbar hernia repair, it is important to be careful not to damage subcostal nerve and iliohypogastric nerve. Self-fixating mesh without fixation is useful due to the prevention from nerve injury. To our best knowledge, this is the first report of single-incision laparoscopic repair for superior lumbar hernia. Single-incision laparoscopic surgery could provide good cosmetic results with minimal incision.

Conclusion

We successfully performed single-incision retroperitoneal laparoscopic repair of superior lumbar hernia using self-fixating mesh.

Broad ligament hernia successfully repaired by single-incision laparoscopy: A case report

A 52-year-old woman with a history of two parturitions presented with lower abdominal pain. Multi-detector CT of the abdomen showed discontinuity of the sigmoid colon near the broad ligament on the left side. We assigned a provisional diagnosis of an internal hernia progressing through a defect in the broad ligament. SILS revealed a total broad ligament defect on the left side but no signs of ischemic, necrotic bowel. We successfully repaired the broad ligament defect with suturing. At the 2-month follow-up, the patient remained well with no signs of recurrence. This case appears to be the first report of a broad ligament hernia successfully diagnosed and repaired by SILS.

Single-incision laparoscopic versus conventional laparoscopic right colectomy: A systematic review and meta-analysis

BACKGROUND

Single-incision laparoscopic surgery has gained widespread attention because of its potential benefits such as less skin incision and faster recovery. Up to now, only one meta-analysis (performed in 2013; including 9 studies, a total of 585 cases) compared single-incision laparoscopic right colectomy (SILRC) with conventional laparoscopic right colectomy (CLRC). An updated meta-analysis was undertaken to explore more convinced comparative findings between SILRC and CLRC.

MATERIALS AND METHODS

The search for studies that compared SILRC with CLRC was done on PubMed, Embase, Web of Science, and the Cochrane Library. A total of 17 studies (including 1778 cases) were identified, the data of appointed outcomes were extracted and analyzed.

RESULTS

Patient demographics (age, gender, body mass index and previous abdominal operation) did not differ significantly. No significant differences were found between SILRC and CLRC in operative time, conversion, reoperation, perioperative complications, postoperative mortality, and 30-days readmission. Pathological outcomes, including lymph nodes harvested, proximal resection margin, and distal resection margin, were similar. SILRC showed less estimated blood loss (weighted mean difference [WMD]: -15.67 ml; 95% confidence interval [CI], -24.36 to -6.98; p = 0.0004), less skin incisions (WMD: -1.56 cm; 95%CI, -2.63 to -0.49; p = 0.004) and shorter hospital stay (WMD: -0.73d; 95%CI, -1.04 to -0.41; p < 0.00001), without publication bias.

CONCLUSION

SILRC may provide a safe and feasible alternative to CLRC with similar short-term outcomes and aesthetic advantage of less skin incision. Well-designed randomized controlled trials, involving large cases and carrying long-term outcomes, are needed.

Application of a commercial single-port device for robotic single-incision distal pancreatectomy: initial experience

PURPOSE

Laparoscopic distal pancreatectomy has proven to be feasible and safe. Moreover, robotic surgery provides unique advantages for pancreatic procedures, although single-incision robotic pancreatic surgery is rarely discussed. We applied the single-port modified platform to accomplish robotic distal pancreatectomy in a series of patients.

METHODS

The subjects of this study were ten patients who underwent robotic distal pancreatectomy in our hospital between July 1, 2015 and Dec 31, 2016. All patients were placed supine in the reverse Trendelenburg position with the legs abducted. Surgery was performed via a trans-umbilical 5.0-cm incision, using a modified single-port platform (LAGIPORT^®) combined with the da Vinci Si Surgical System. The three arms and scope (30-degree up) were inserted through the LAGIPORT^® and positioned in a triangle. Endoscopic ultrasound was used to localize the tumor and plan the resection margin. We recorded the surgical time, operation time, blood loss, postoperative pain score, hospital stay, and complications.

RESULTS

The surgical time was 236 ± 32 min, the operation time was 172 ± 30 min, and the blood loss was 149 ± 65 ml. All patients underwent robot-assisted distal pancreatectomy without conversion. The average pain score on postoperative day (POD) 3 was 4.5 ± 1. Complications included subsplenic hematoma (n = 1) and minor pancreatic leakage (n = 2). There was no surgical mortality.

CONCLUSIONS

Our results demonstrate the safety and efficiency of robotic single-incision distal pancreatectomy via the modified platform (LAGIPORT^®).
