Objective: The purpose of this article was to compare the effectiveness and safety of single-stage (laparoscopic cholecystectomy [LC] plus laparoscopic common bile duct exploration [LCBDE]) with two-stage (LC plus endoscopic retrograde cholangiopancreatography (ERCP)/endoscopic sphincterotomy [EST]) in management for concomitant gallstones and common bile duct (CBD) stones. Materials and Methods: Systematic review and meta-analysis of randomised controlled trials (RCTs) comparing outcomes following single-stage with two-stage management for concomitant gallstones and CBD stones published from 1990 to 2017 in PubMed, Embase and the Science Citation Index. The primary outcomes were stone clearance from the CBD, post-operative morbidity and mortality. The secondary outcomes were retained stone, conversion to other procedures, length of hospital stay and total operating time. Pooled risk ratio (RR) or weighted mean differences (WMD) with 95% confidence intervals (95% CIs) were calculated using either the fixed effects model or random effects model. Results: Eleven RCTs studies were included in this analysis. These studies included a total of 1338 patients: 666 underwent LC + LCBDE and 672 underwent LC + ERCP/EST. The meta-analysis showed that no significant difference was noted between the two groups regarding CBD stone clearance (RR: 1.06; 95% CI: 0.99–1.14; P= 0.12), post-operative morbidity (RR: 1.03; 95% CI: 0.79–1.34; P= 0.81), mortality (RR: 0.30; 95% CI: 0.06–1.41; P= 0.13), retained stone (RR: 0.91; 95% CI: 0.57–1.47; P= 0.71), conversion to other procedures (RR: 0.80; 95% CI: 0.55–0.16; P= 0.23), length of hospital stay (WMD: 1.24, 95% CI: 3.57–1.09, P= 0.30), total operating time (WMD: 25.42, 95% CI: 22.38–73.22, P= 0.30). Conclusion: Single-stage is efficient and safe in the treatment of patients with concomitant gallstones and CBD stones while avoiding the second procedure. In selected patients, single-stage management for concomitant gallstones and CBD stones might be considered as the preferred approach. However, the findings have to be carefully interpreted due to the existence of heterogeneity, in addition, patient's condition, operator's experience also should be taken into account in making treatment decisions.

Introduction: There are limited data to date regarding laparoscopic liver resection (LLR) for spontaneously ruptured hepatocellular carcinoma (srHCC). We performed this study to determine the safety and feasibility of LLR for srHCC. Materials and Methods: We conducted a retrospective review of all patients who underwent liver resection for srHCC from 2000 to 2018. A total of five patients underwent LLR for srHCC, and they were matched to 10 patients who underwent open liver resection (OLR) for srHCC to perform a 1:2 comparison. A separate cohort of patients who underwent LLR for non-ruptured HCC (nrHCC) was also compared against the laparoscopic group. Results: The comparison between LLR versus OLR for srHCC demonstrated no significant differences in baseline characteristics between both groups. There was also no significant difference in perioperative outcomes such as median operating time, estimated blood loss (EBL), rate of blood transfusion, post-operative median length of stay (LOS), overall complication rates, major morbidity rates and 90-day mortality rates. Comparison between LLR for srHCC and LLR for nrHCC demonstrated no significant differences in baseline characteristics between both groups. There was also no significant difference in key perioperative outcomes such as median operating time, EBL, rate and volume of blood transfusion, median post-operative LOS, morbidity rates or mortality rates. Conclusion: LLR may be performed safely in selected cases of srHCC. These patients have comparable perioperative outcomes as those who undergo OLR for srHCC and LLR for nrHCC.

Introduction: Open surgical management is considered as ‘standard of care’ for patients with Mirizzi's syndrome (MS). Laparoscopic management of MS has been reported, but comparative studies are lacking. Patients and Methods: This retrospective study included patients with MS who were treated by a single surgical team from May 2009 to December 2017. Patients with total laparoscopic surgery were included in laparoscopic group (LG) and patients with total open surgery were included in open group (OG). Patients with conversion to open surgery and patients with gallbladder cancer (GBC) were excluded from the study. Results: Total patients were 75; six patients with GBC and 11 patients with open conversion were excluded from comparison. LG had 32 patients and OG had 26 patients. Demographic, clinical and laboratory parameters were similar. Laparoscopic versus open preoperative diagnosis rate was 87.5% versus 69.2% (P = 0.08), respectively. OG had a large number of patients with concomitant bile duct stone; therefore, bile duct exploration rate was higher in OG (P = 0.009). Laparoscopic versus open, mean duration of surgery – 137 min versus 145 min (P = 0.664); mean blood loss – 45 mL versus 70 mL (P = 0.04); mean hospital stay – 4.5 versus 8.1 days (P = 0.027). Post-operative complication rate was 21.8% in LG and 42.3% in OG (P = 0.355); bile leak was noted in OG only (P = 0.042). LG versus OG mean follow-up was 50 versus 38 months (P = 0.189); no remote complication was observed in both groups. Conclusion: The results of laparoscopic surgery in patients with Mirizzi's syndrome are not inferior to that of open surgery; rather it may help to improve perioperative outcome in selected patients.

Background: The optimal approach to resection for Siewert type II adenocarcinoma of the oesophagogastric junction (AEG) is still controversial. Our novel procedures and experience with a minimally invasive abdominal and left thoracic approach (MALTA) for Siewert type II AEG are described. Patients and Methods: Intra- and post-operative outcomes for MALTA were assessed in seven consecutive patients with a preoperative diagnosis of Siewert type II AEG at Hokkaido University Hospital. Results: None of the patients were converted to open surgery. The mean surgical duration was 434.0 ± 71.4 min, and mean blood loss was 20.7 ± 16.7 ml. On pathological examination, the median proximal margin was 24.6 ± 12.5 mm. No reoperations were needed, and there were no surgery-related complications. Conclusions: This novel technique shows considerable advantages, such as ensuring the proximal margin, intrathoracic oesophagojejunostomy and increased operative field exposure of the lower mediastinal area for Siewert type II AEG.

Background: Laparoscopic liver resection has become popular recent years. Laparoscopic left lateral sectionectomy (LLS) is now a standard operation with sufficient safety and feasibility. To improve the benefits of minimally invasive surgery, we invented and have been performing a reduced port LLS procedure using 3 ports since 2009. Materials and Methods: All patients who underwent LLS at Toranomon Hospital (Tokyo, Japan) were included, except for patients with a previous history of upper abdominal surgery or those who had undergone the simultaneous resection of another organ. An essential point of this procedure was the extracorporeal traction of the divided round ligament using a ligature. As a result, the operator was able to perform the parenchymal transection within a good operative field. Results: Twelve patients were enrolled in the study. All the patients had a Child-Pugh classification of Class A. The median indocyanine green retention rate at 15 min was 9.5%. Compared with previously reported results for conventional LLS, the median operation time (82.5 min), blood loss (0 mL) and rate of blood transfusion (0%) were lower for the 3-port LLS procedure. The rates of complications (9%) and a positive surgical margin (0%) were similar to those reported for the conventional approach. Conclusion: Three-port LLS appears to be a safe and feasible procedure.

Background: Laparoscopic anti-reflux surgery could be of benefit in a subset of elderly patients with gastroesophageal reflux disease. However, there are few reports that have evaluated the long-term results. This study examined the effects of age on the short- and long-term (for at least 5 years) outcomes after laparoscopic Nissen fundoplication (LNF). Patients and Methods: Patients were divided into four groups as follows: young (18–49); adult (50–69); and elderly (70–84), and very elderly (85–91). The database (recorded prospectively) included operating duration, conversion, intra- and early post-operative complication and late outcomes. Mean follow-up was 14.5 years (range 5–24 years). Results: Five hundred and sixty-nine patients met the inclusion criteria: young n = 219 (38.4%); adult n = 248 (43.5%); elderly n = 91 (16.0%) and very elderly n = 11 (1.9%). Hiatal hernia (type I and III) was significantly less frequent in young and adult patients (P < 0.0001). The operation was significantly longer in elderly and very elderly patients (P < 0.001); the use of drains (P < 0.001) and grafts (P < 0.0001) for hiatal hernia repair was less in young and adult patients. The hospital stay, conversion (5.4%), intra-operative and early post-operative complications were not influenced by age. Dysphagia was evenly distributed among the groups. Forty-eight (8.4%) patients had recurrence: 15 in the young group (6.8%), 18 in the adult group (7.2%), 11 in the elderly group (12%) and 4 in the very elderly group (36.3%) (P < 0.0001). Conclusions: Age does not influence short- and long-term outcomes following LNF. Control of reflux in the elderly is worse than adult patients. Therefore, ageing is a relative contraindication to LNF.

Introduction: Laparoscopic repair is now the treatment of choice for most cases of ventral/incisional hernia. Although the technique has undergone many refinements, there is no standard technique for difficult or complicated hernias. Aim: The aim of this study was to show the different innovative methods used to treat difficult ventral hernia through hybrid techniques. Materials and Methods: A total of 75 (n = 75) patients underwent Laparoscopic Ventral Hernia Hybrid Mesh Repair (LVHHMR) by our surgical unit between January 2014 and December 2016. Three different techniques of repairing the defects were used. Mesh fixation time, post-operative pain score (visual analogue score) and follow-up for pain and recurrence (at 6 months, 12 months and 24 months) were recorded and analysed. Results: Out of 75 patients (20 men and 55 women), the median age was 45 years and body mass index of the patients was 25–35. Types of hernias operated were paraumbilical hernias, incisional and recurrent hernias. The techniques used were (1) laparoscopic adhesiolysis, open sac excision with closure of defect and laparoscopic mesh placement, (2) laparoscopic adhesiolysis, omphalectomy with closure of defect and laparoscopic mesh placement and (3) open adhesiolysis, sac excision with closure of defect and laparoscopic mesh placement. Five patients required analgesics for 48 h. No patients complained of pain at follow-ups (1 month, 6 months, 12 months and 24 months). Mean hospital stay postoperatively was 2–3 days. Conclusion: LVHHMR is safe and feasible approach for complicated/difficult ventral hernias. However, further larger studies are required to establish these methods as gold standard.

Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric surgery worldwide. De novo gastroesophageal reflux disease after LSG has been reported in the range of 0%–34.9%. Benign lower oesophageal peptic stricture is rare and has not been reported till date. We present the first case report of benign oesophageal peptic stricture post-sleeve gastrectomy and its management. The management modalities for peptic stricture post-LSG include proton pump inhibitors, endoscopic dilatation and surgical management. Revisional Roux-en-Y gastric bypass along with optimal usage of serial dilatation and medical treatment has been shown to be an effective treatment for the same.

Background: Laparoscopic adjustable gastric banding (LAGB) revision surgery is often necessary because of its high failure rate. The objective of this study was to demonstrate that better patient selection, when converting a failed LAGB to a laparoscopic sleeve gastrectomy (LSG) as a one-stage revision procedure, is safe, feasible and improves the complication rate. Patients and Methods: A retrospective chart review was performed on patients who underwent a one-stage conversion of failed gastric banding to a LSG. Collected data included age, sex, body mass index (BMI), intraoperative complications, length of stay and post-operative complications. The results were compared to a previous study of 90 cases of LSG as a revision procedure for failed LAGB. Results: There were 75 patients in the current study, 61 women and 14 men, aged 25–67 (average: 46), with a mean BMI of 45 kg/m² (32–66). Seventy patients (93.3%) were operated for insufficient weight loss and 5 patients (6.7%) for intolerance to the band. In our previous study, 35 patients (39%) were operated for slippage, erosion or obstruction and 14 (15.6%) had post-operative complications as opposed to only 4 patients (5.3%) in this series (P = 0.0359). Gastric leak also improved to 1.3% compared to 5.5% previously. Average hospitalisation time was 2.5 days (1–40). Conclusions: Rigorous patient selection, without band complications such as slippage, erosion or obstruction, allows for a significantly lower rate of operative complications for a one-stage conversion of failed gastric banding to a LSG.

Background: Laparoscopic resection for rectal cancer (LRR) has gained popularity because of better short-term outcomes and less post-operative morbidity. However, LRR is still not endorsed as a standard of care mainly due to concerns centred on oncological safety in comparison with open approach. Moreover, two recent randomised trials (Australian Laparoscopic Cancer of the Rectum [ALaCaRT] and the American College of Surgeons Oncology Group [ACOSOG] Z6051) have failed to prove that LRR is non-inferior to open resection. Studies on oncological adequacy of LRR in the Indian population in terms of quality of mesorectal excision are scarce. In this article, we aim to audit the oncological adequacy of LRR in our centre and thereby critically analyse the reliability of extrapolation of results of ALaCaRT and ACOSOG trials to the Indian population. Methods: We retrospectively analysed the oncological adequacy of LRR in terms of completeness of total mesorectal excision (TME), distal and circumferential resection margin (CRM) status and nodal harvest in patients with rectal cancer who underwent LRR between January 2016 and June 2018 at our centre. Results: Of 157 patients included in this study, a complete TME was achieved in 148 (94.26%) patients and nearly complete in 7 (4.46%) patients. A safe CRM (≥1 mm) was obtained in 151 (96.18%) patients. Distal margin results were negative in 155 (98.73%) patients. Average nodal harvest was 19.86 ± 9.28. Overall surgical success, calculated as a composite measure of negative distal margin and negative CRM and complete TME was 95.54%. Conclusion: Good quality rectal cancer resection can be achieved by experienced laparoscopic surgeons without compromising oncological safety.

Background: Robotic-assisted surgery is becoming increasingly used in colorectal operations. It has many advantages over laparoscopic surgery including three-dimensional viewing, motion scaling, improved dexterity and ergonomics as well as increased precision. However, there are also disadvantages to robotic surgery such as lack of tactile feedback, cost as well as limitations on multi-quadrant surgeries. The purpose of this study was to compare the rate of conversion to an open surgery in patients undergoing robotic-assisted colorectal surgery and traditional laparoscopic surgery. Methods: Patients undergoing minimally invasive colorectal surgery for neoplastic and dysplastic disease from 2009 to 2016 were identified and examined retrospectively. The statistical software SAS, manufactured by SAS Institute, Cary, North Carolina. Continuous variables were analysed using analysis of variance test. Chi-square test was used to analyse categorical variables. P <0.05 was considered statistically significant. Results: Two hundred and thirty-five patients were identified that underwent minimally invasive colorectal surgery. One hundred and sixty-four underwent laparoscopic resection and 71 underwent robotic-assisted resection. There was no statistical difference in gender or race between the two groups (both P > 0.05). Patients that underwent robotic-assisted resection were slightly younger than patients that underwent laparoscopic resection (61.6 years vs. 65.6 years; P= 0.02). When examining conversion to an open procedure, patients that underwent robotic-assisted resection had a significantly lower chance of conversion than did the patients undergoing a laparoscopic approach (11.27% vs. 29.78%; P= 0.0018). Conclusion: Conversion rates from a minimally invasive procedure to an open procedure appear to be lower with robotic-assisted surgery compared to laparoscopic surgery.

Background: Transoral thyroid surgery represented by the da Vinci system is attracted attention and performed by several institutions. However, the current available da Vinci system still has some limitations to be improved for transoral thyroid surgery including high cost of equipment and expendables, larger diameter scope and instruments and no tactile sensation. It triggered us interest in more easily available robotic scope holder. Soloassist II (AktorMed GmbH, Barbing, Germany) is an active endoscope holder system which is controlled by a joystick. It has total six joints: three joints which are controlled by computer, one is controlled by manual and two act as a gimbal joint following the movement of the main body. Materials and Methods: We tried transoral endoscopic thyroidectomy using Soloassist II (AktorMed GmbH, Barbing, Germany) in December 2017 in our hospital. Results: We successfully performed four thyroid lobectomies in four patients with Soloassist II. We refined and described surgical procedures in each step using video clips. It provided an excellent vibration-free stable surgical view which enabled fatigue-free work, without shaking or tilting the horizon. The surgeon could perform transoral endoscopic thyroid surgery with only one assistant surgeon. Docking and preparation time for Soloassist was within 10 min in all four patients. The setup and dismantling could be performed parallel to the usual workflow. No complication was reported by any patient. Conclusions: The robotic scope holder (Soloassist II) seems to be safe and feasible equipment for performing transoral endoscopic thyroid surgery. Several possible advantages could be expected with this robotic scope holder.

Introduction: The da Vinci^® X hybrid systems (Intuitive Surgical^®, Sunnyvale CA) provides standard sites recommendations for port placement during robotic surgery; including that for colorectal procedures. The author's encountered challenges while adhering to the provided instructions, such as clash of instruments and arms and need for additional ports, and hence to overcome these challenges attempted a few innovative technical modifications. The surgical results as well as merits of the revised Indian (Manipal) port placement with single docking technique are presented here. Methods: Twenty patients underwent robotic rectal resection at the Department of Surgical Oncology and Robotic Surgery, Manipal Comprehensive Cancer Centre, Bengaluru, India, between December 2017 and June 2018. A randomised controlled study was conducted to compare the two techniques. Ten patients were operated using hybrid da Vinci^® ‘X’ system using the manufacturer's recommendations and 10 by the modified Indian (Manipal) port placement with a single docking technique. Result and Conclusions: The Indian (Manipal) modifications of port placements are optimal for colorectal procedures such as low anterior resection as well as for ultralow anterior resections. The intraoperative parameters compared between the recommendations of the Intuitive^® (da Vinci^® systems) and attempted modifications demonstrated statistically significant advantages with the use of the revised techniques. The improvements offered by this modification include no additional requirements of ports or staplers, lesser clash amongst instruments as well as arms, better mobilisation of splenic flexure amongst others.

Anorectal malignant melanoma is a very rare but aggressive cancer which carries poor prognosis. Surgical intervention is the main management but whether wide local excision or abdominoperineal resection has better survival benefit remains controversial. However, robotic-assisted restorative proctectomy with coloanal anastomosis with intersphincteric resection (ISR) has not been reported yet. Hence, we presented a case with anorectal malignant melanoma treated with robotic-assisted ISR with coloanal anastomosis. The patient has satisfied post-operative life quality, and no local recurrence was noted after 3-year follow-up.

The laparoscopic management of hepatobiliary pathology is an established mode of treatment. Incomplete excision of choledochal cyst with the resultant complications is a distinct surgical pathology, the treatment of which can be rendered based on the philosophy of minimally invasive approach which is now an acceptable treatment for the primary condition itself. We describe a case of hepaticojejunostomy site stricture associated with incomplete cyst excision managed laparoscopically. A redo procedure is technically demanding considering the presence of adhesions and a difficult to discern anatomy, but resulted in an excellent outcome. At centres with significant experience in laparoscopic surgery, redo procedures with a favourable impression on pre-operative work-up can be effectively treated with laparoscopy.

Gall bladder perforation as a sequel of typhoid-induced acalculous cholecystitis is a rare clinical encounter, reported sparsely in literature. Here, we discuss a case wherein successful laparoscopic management of typhoid-induced gall bladder perforation was performed. A 24-year-old female presented with a history of 5 days of fever and acute pain in the abdomen for 2 days. Computed tomography scan suggested gall bladder perforation which was confirmed on diagnostic laparoscopy. Laparoscopic cholecystectomy with peritoneal lavage was performed. The patient did well postoperatively and was discharged on post-operative day 4 after drain removal. One should be aware about the possibility of gall bladder perforation as a sequel of acalculous cholecystitis in typhoid fever. Minimal access surgery techniques can be applied for confirming the diagnosis as well as the definitive treatment.

A rare case of internal herniation of a peritoneal defect in the pouch of Douglas is being reported. It presented as a case of intestinal obstruction, which after investigation, on laparoscopic exploration was found to be a case of internal hernia getting obstructed in the pouch of Douglas. It was successfully treated by marsupialisation of the defect laparoscopically. A 33-year-old female presented with pain abdomen and vomiting. On investigations, she was found to be having a small intestinal obstruction. Conservative trial failed and then diagnostic laparoscopy was done, which revealed a peritoneal defect in the pouch of Douglas with the incarcerated distal ileal loop. Contents were reduced, and laparoscopic marsupialisation of the peritoneal defect was done. A rare case of defect in peritoneum with no defect in muscular layer in the pouch of douglas. Internal hernia is being reported and successfully treated laparoscopically by marsupialisation for the first time.

Spontaneous splenic rupture is a rare entity that requires high index of suspicion for diagnosis. Usually, it occurs due to underlying pathology that could be inflammatory, neoplastic or infectious. However, there are also cases of spontaneous splenic rupture in a normal-sized spleen without obvious pathologic process. In our case, the patient suffered a spontaneous splenic rupture 1 week after laparoscopic appendectomy due to acute appendicitis. Histopathologic examination revealed a normal-sized spleen without any obvious pathology. In our patient, we did not found any explanation for a spontaneous splenic rupture, besides her primary inflammatory condition.
