Background: Radical prostatectomy (RP) represents an important acquired risk factor for the development of primary inguinal hernias (IH) with an estimated incidence rates of 15.9% within the first 2 years after surgery. The prostatectomy-related preperitoneal fibrotic reaction can make the laparoendoscopic repair of the IH technically difficult, even if safety and feasibility have not been extensively evaluated yet. We conducted a systematic review of the available literature. Methods: A comprehensive computer literature search of PubMed and MEDLINE databases was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Terms used to search were ('laparoscopic' OR 'laparoscopy') AND ('inguinal' OR 'groin' OR 'hernia') AND 'prostatectomy'. Results: The literature search from PubMed and MEDLINE databases revealed 156 articles. Five articles were considered eligible for the analysis, including 229 patients who underwent 277 hernia repairs. The pooled analysis indicates no statistically significant difference of post-operative complications (Risk Ratios [RR] 2.06; 95% confidence interval [CI] 0.85–4.97), conversion to open surgery (RR 3.91; 95% CI 0.85–18.04) and recurrence of hernia (RR 1.39; 95% CI 0.39–4.93) between the post-prostatectomy group and the control group. There was a statistically significant difference of minor intraoperative complications (RR 4.42; CI 1.05–18.64), due to an injury of the inferior epigastric vessels. Conclusions: Our systematic review suggests that, in experienced hands, safety, feasibility and clinical outcomes of minimally invasive repair of IH in patients previously treated with prostatectomy, are comparable to those patients without previous RP.

Retrorectus sublay mesh repair using polypropylene mesh: Cost-effective approach for laparoscopic treatment of ventral abdominal wall hernias

Journal of Minimal Access Surgery 2019 15(4):287-292

Introduction: Laparoscopic repair of ventral abdominal hernias has become a standard of care. The surgery involves placement of a composite mesh with 3–5 cm overlap at the edges of the defect. The disadvantage of this repair is one, the composite mesh used for intraperitoneal placement is quite costly and two, it leaves a foreign body inside the peritoneal cavity, with the potential to cause problems in the future. To circumvent both these issues, we have developed a new approach, called the retrorectus sublay Mesh (RRSM) repair, which allows placement of a plain polypropylene mesh in an extraperitoneal plane. Patients and Methods: Patients with paraumbilical hernia and lower midline incisional hernias were included in this pilot study performed at a single centre by the same surgeon. The steps of the technique are described in detail. Results: Since 2016, a total of 52 patients were operated by this technique, including both male and female patients. It included patients with para-umbilical hernias as well as incisional hernias. The RRSM repair could be successfully carried out in all the patients. In six of the patients, transversus abdominis release was added as the defect size was large to allow closure of the defect. The results were satisfactory with a low morbidity and no mortality. Conclusion: In our opinion, the RRSM technique is an important tool in the armamentarium of the laparoscopic surgeon dealing with ventral abdominal hernias, allowing placement of polypropylene mesh in an extraperitoneal space. It allows significant cost savings as compared to the prevalent intraperitoneal onlay mesh repair.

Objective: Robot-assisted neck dissection requires a larger wound, is expensive and requires specialised equipment which is not easily available. We have developed an inexpensive minimally invasive neck dissection (MIND) procedure using simple endoscopic instruments in the past. This study was conducted to evaluate the safety, efficacy and reproducibility of the technique. Materials and Methods: From January 2013 to December 2016, we performed MIND on 45 patients with oral cancer using the standard endoscopic equipment. CO2 gas insufflation was used to create the working space. Intra-operative data, post-operative data and pathological characteristics were evaluated and overall survival (OS) and disease-free survival (DFS) Kaplan–Meier curves were compared using the Log-Rank test. Results: Median operative time was 130 (80–190) min with a mean blood loss of 63 (20–150) ml. Major intra-operative complications were not observed. The median number of nodes retrieved was 14 (range: 7–38). Three patients with a positive lymph node were advised to undergo adjuvant radiotherapy. After consultation, 12 out of 13 tongue cancer patients with a tumour depth >3 mm underwent adjuvant radiotherapy. Mean follow-up period was 31.5 (95% confidence interval [CI] 27.9–35.1) months and 27.8 (95% CI 23.6–32.1) months for OS and DFS, respectively. Four (8.9%) deaths and 8 (17.8%) recurrences were observed. The 3-year OS and DFS was 91.1% and 82.2%, respectively. Conclusion: MIND is aesthetically better than conventional procedures for oral cancer patients due to its safety, efficacy and reproducibility at any centre using the standard laparoscopic equipment.

Aims: We aimed to evaluate the safety and feasibility of laparoscopic total extraperitoneal (TEP) inguinal hernia repair in patients with the continuation of their antithrombotic agents. Settings and Design: This was prospective cohort study. Materials and Methods: A total of 115 patients who underwent TEP inguinal hernia repair between January 2015 and September 2016 were included in the analysis. Seventeen patients continued their antithrombotics (antithrombotic group); the other 98 had not been on antithrombotics (control group). Statistical Analysis Used: The analysis was performed by using Mann–Whitney U-test, Chi-square or Fisher's exact test. Results: The antithrombotic group had a greater mean age (65.9 ± 8.0 vs. 57.7 ± 13.6,P= 0.002) and higher prevalence of hypertension (64.7% vs. 33.7%,P= 0.015), cardiovascular diseases (64.7% vs. 7.1%,P < 0.001), atrial fibrillation (23.5% vs. 0,P < 0.001), ischaemic heart disease (35.3% vs. 0,P < 0.001) and the American Society of Anaesthesiologists ≥2 (94.1% vs. 81.6%,P= 0.005). The operation time for the antithrombotic group was longer than that of the control group (92.06 ± 32.81 min vs. 72.33 ± 20.99 min,P= 0.015). None experienced conversion to open surgery in either group. There was no difference in the post-operative complications (29.4% vs. 28.6%) and sero-haematoma formation (23.5% vs. 11.1%). The analgesic requirement, hospital stays (23.72 ± 7.74 vs. 22.35 ± 10.33 h) and the time for return to normal daily activity (3.56 ± 1.74 vs. 3.63 ± 1.90) were not statistically different between the two groups. None in either group experienced major cardiovascular events within 30 days. Conclusions: Laparoscopic TEP inguinal hernia repair can be safely performed in patients with the continuation of their antithrombotic agents in experienced hands.

Aim: To construct and validate a cost-effective indigenously made retrieval system (Modified Nadiad bag) in minimal access urology. Method: The components of the modified Nadiad bag are a polyethylene roll, fishnet thread, and a 5 Fr ureteral catheter. The bag is indigenously made in our institute and used for organ retrieval after proper sterilization. The video recordings of entrapments and retrievals done over the past few months were reviewed. The procedures under review in which the bag was used were: Robot Assisted Radical Prostatectomy (50 cases), laparoscopic radical nephrectomy (50 cases), laparoscopic simple nephrectomy (50 cases) and laparoscopic adrenalectomy (18 cases). We also compared the retrieval time with experts and novices. Results: The retrieval times, the organ size (largest dimension) and specimen weight were records for each case. Multivariate analysis of the data was done and we extrapolated the retrieval time with organ size, specimen weight and expertise of the surgeon. There was no significant difference among expert surgeons and novice surgeons with regards to retrieval times (p value = 0.29), with regards to organ size (p value = 0.83) and with regards to specimen weight (p value = 0.99). Conclusion: Our design of retrieval system offers a cost-effective option which is easy to make, without the risk of tumor seeding and without the need for separate access sheath. It's a retrieval system which has proved its efficacy in laparoscopic as well as robotic procedures with no bearing on the expertise of the surgeon involved.

Journal of Minimal Access Surgery 2019 15(4):311-315

Background: The aim of this study is to explore the application value of layered suture technique in two-port laparoscopic choledocholithotomy with primary suture. Materials and Methods: A prospective study of 267 patients received laparoscopic common bile duct choledocholithotomy with primary suture in our hospital from January 2014 to July 2017. Of these cases, layered suture technique was utilised in 110 patients, and single-suture technique was used in 157 patients. The operation time, post-operative hospital stay and post-operative complications were compared between the two groups. Results: Two groups of patients were operated smoothly, with no conversations to laparotomy. Post-operative recovery was symptom free. The operative time was not significantly different between the two groups of patients (t = −'0.587,P= 0.086). The post-operative hospital stay and incidence of post-operative bile leakage were significantly lower in layered suture group than those in single-layer suture group ([7.6 ± 1.8] days vs. [5.8 ± 1.7] days, t = 2.776,P= 0.000; 4.5% [5/110] vs. 20.4% [32/157], χ2 = 9.885,P= 0.002). In the single-layer suture group, the incidence of post-operative bile leakage was significantly higher in patients complicated with acute cholangitis (44.4% [12/27] vs. 15.4% [20/130], χ2 = 11.634,P= 0.001), whereas in the layered suture group, the incidence of post-operative bile leakage was insignificantly different among patients with and without acute cholangitis (11.8% [2/17] vs. 3.2% [3/93], χ2 = 0.848,P= 0.357). Conclusion: Application of layered suture technique in laparoscopic choledocholithotomy with primary suture is feasible and safe, with advantages of less bile leakage and shorter hospital stay.

Introduction: Reduced port laparoscopic Well's procedure (RPLWP) is a novel technique used to overcome the limitations of single-incision laparoscopic surgery. The aim of this study was to compare outcomes between RPLWP and conventional laparoscopic Well's procedure (CLWP) and to investigate the learning curve of RPLWP. Patients and Methods: From January 2006 to March 2017, a retrospective review of a prospectively maintained laparoscopic surgery database was performed to identify patients had undergone CLWP and RPLWP. From these patients, each of 10 cases were manually matched for age, sex, body mass index. From January 2006 to March 2015, CLWP was used for all procedures whereas, from April 2015, RPLWP was routinely performed as a standard procedure for rectal prolapse. Results: No significant differences were observed between the two groups in terms of operating time, blood loss, intraoperative complications, and conversion to CLWP or open rectopexy. Based on the postoperative outcomes, the hospital stay was significantly shorter in the RPLWP group. The estimated learning curve for RPLWP was fitted and defined as y = 278.47e-0.064x with R2 = 0.838; therefore, a significant decrease in operative time was observed by using the more advanced surgical procedure. Conclusions: RPLWP is an effective, safe, minimally invasive procedural alternative to CLWP with no disadvantage for patients when a skilled surgeon performs it.

Context: Primary closure of the common bile duct (CBD) without drainage is considered a suitable approach after laparoscopic CBD exploration (LCBDE); however, the risk of post-operative bile leakage is high. Up to now, it has not been clear whether human fibrin sealant can reduce post-operative bile leakage of the primary suture. Aims: In this study, we evaluated the role of human fibrin sealant in primary closure of the CBD after LCBDE. Subjects and Methods: Patients with choledocholithiasis who had undergone primary duct closure of the CBD after LCBDE were divided into two groups according to whether fibrin sealant was used. Statistical Analysis Used: Fisher's exact test or the Chi-square test was used for categorical variables to calculate frequencies and percentages between the groups. The Student's t-test was used to compare the means of the continuous variables between the groups. Results: The human fibrin sealant group had a lower rate of post-operative bile leakage compared to the other group (P < 0.05). There were no significant differences in additional parameters such as operative time, post-operative stay duration, time to drain removal, bile duct stenosis, acute allergic reaction and overall mortality. Conclusions: Human fibrin sealant can reduce post-operative bile leakage in primary closure of CBD after LCBDE in patients with choledocholithiasis.

Bao Jin, Shunda Du, Haifeng Xu, Yongchang Zheng, Xin Lu, Xinting Sang, Yilei Mao

Journal of Minimal Access Surgery 2019 15(4):325-330

Background: Laparoscopic hepatectomy is more conducive to the rapid rehabilitation of patients after surgery compared with open hepatectomy. However, there have been no reports on performing laparoscopic resection for liver metastases in enterostomy patients. Materials: From December 2016 to April 2017, the Liver Surgery Department of the Peking Union Medical College Hospital received three patients who had focal liver lesions after colorectal cancer surgery and enterostomy. We performed laparoscopic hepatectomy for these three patients and reviewed relevant literature. Results: All of these three patients' post-operative recovery was good. We found three different positions of the stomas and the corresponding abdominal adhesions in these three patients. We also summarised several possible related surgical techniques. Conclusion: For patients with colorectal cancer and enterostomy after an operation, implementation of laparoscopic hepatectomy is feasible. Further research is still required for a more comprehensive assessment of this surgical approach.

Introduction: Minimal Invasive Surgery of oesophageal cancers is gaining popularity. We have published our Thoracoscopic Esophagectomy results. The present study focuses on our expertise of TransHiatal Esophagectomy. Materials and Methods: 287 patients underwent Esophagectomies for Cancer of Esophagus at Galaxy Care Laparoscopy Institute from January 2010 to December 2014 after thorough assesment. Out of these, 81 patients underwent laparoscopic trans hiatal esophagectomies. Their charts were reviewed retrospectively for intraoperative and postoperative results. The median follow up was 28 months. Results: Out of 81 patients,76 patients had R0 resection and 5 had R1. The average lymphnode yield was 20,average survival was 28months. 3 patients had local recurrence,18 had regional recurrence and 30 had distant recurrence. Average operating time was 140 min,mean blood loss was 80 ml. Average Post-operative ICU stay was 1 day and hospital stay 7 days. Conclusion: Classic THE has limitations which can be overcome by the use of laparoscopic techniques. Laparoscopic approach for THE has better magnified vision facilitating better clearance under vision. Hence we recommend laparoscopic technique for THE to minimize morbidity and improve oncologic results.
