Application value of hand-sewn anastomosis in totally laparoscopic total gastrectomy for gastric cancer

BackgroundDigestive tract reconstruction in totally laparoscopic total gastrectomy can be divided into two types: instrument anastomosis and hand-sewn anastomosis. This study explored the feasibility and safety of hand-sewn sutures in esophagojejunostomy of totally laparoscopic total gastrectomy, compared with instrument anastomosis using an overlap linear cutter.MethodsThis retrospective cohort study was conducted from January 2017 to January 2020 at one institution. The clinical data of 50 patients who underwent totally laparoscopic total gastrectomy, with an average follow-up time of 12 months, were collected. The clinicopathologic data, short-term survival prognosis, and results of patients in the hand-sewn anastomosis (n=20) and the overlap anastomosis (n=30) groups were analyzed.ResultsThere were no significant differences between the groups in sex, age, body mass index, American Society of Anesthesiologists score, tumor location, preoperative complications, abdominal operation history, tumor size, pTNM stage, blood loss, first postoperative liquid diet, exhaust time, or postoperative length of hospital stay. The hand-sewn anastomosis group had a significantly prolonged operation time (204±26.72min versus 190±20.90min, p=0.04) and anastomosis time (58±22.0min versus 46±15.97min, p=0.029), and a decreased operation cost (CNY 77,100±1700 versus CNY 71,900±1300, p<0.0001). Postoperative complications (dynamic ileus, abdominal infection, and pancreatic leakage) occurred in three patients (15%) in the hand-sewn anastomosis group and in four patients (13.3%) in the overlap anastomosis group (anastomotic leakage, anastomotic bleeding, dynamic ileus, and duodenal stump leakage).ConclusionThe hand-sewn anastomosis method of esophagojejunostomy under totally laparoscopic total gastrectomy is safe and feasible and is an important supplement to linear and circular stapler anastomosis. It may be more convenient regarding obesity, a relatively high position of the anastomosis, edema of the esophageal wall, and short jejunal mesentery.

Enterococcus faecalis Is Associated with Anastomotic Leak in Patients Undergoing Colorectal Surgery.

Background: Anastomotic leak is among the most dreaded complications in patients undergoing colorectal surgery. We have discovered that in rodents, collagenase-producing bacteria, particularly Enterococcus faecalis, promotes anastomotic leak by degrading healing anastomotic tissue. Yet, it is unclear if these organisms play a role in humans. Patients and Methods: Patients undergoing colorectal resection at the University of Chicago from July 2014 through June 2019 who developed a post-operative infection were stratified into infections that resulted from an anastomotic leak, a Hartmann pouch stump leak, or a deep infection without an associated staple line leak. Results: Forty-two patients had available culture data. Of these patients, 19 were found to have an anastomotic leak, 7 had a stump leak, and 16 had a deep infection that was not associated with a staple line. Enterococcus faecalis was identified in 24% of all infections and was associated with the development of anastomotic leak (p = 0.029). When the organisms were classified into their known ability to produce collagenase, 74% of patients with an anastomotic leak were colonized with collagenase-producing organisms, compared with only 28% of patients with a deep infection or stump leak (p = 0.022). Antibiotic-resistant organisms were more common in patients with anastomotic leak (p = 0.01). Conclusions: Collagenase-producing and antibiotic-resistant organisms are more prevalent in anastomotic leak infections compared with other deep or organ/space infections. This lends evidence to a bacterial driven pathogenesis of leak and suggests that targeting these organisms may be a novel strategy to reduce this complication.

Efficacy of endoscopic management for anastomotic leakage after gastrectomy in patients with gastric cancer

BackgroundAnastomotic leakage (AL) after gastrectomy in gastric cancer patients is associated with high mortality rates. Various endoscopic procedures are available to manage this postoperative complication. The aim of study was to evaluate the outcome of two endoscopic modalities, clippings and stents, for the treatment of AL.Patients and methodsThere were 4916 gastric cancer patients who underwent gastrectomy between December 2007 and January 2016 at the National Cancer Center, Korea. A total of 115 patients (2.3%) developed AL. Of these, 85 patients (1.7%) received endoscopic therapy for AL and were included in this retrospective study. The endpoints were the complete leakage closure rates and risk factors associated with failure of endoscopic therapy.ResultsOf the 85 patients, 62 received endoscopic clippings (with or without detachable snares), and 23 received a stent insertion. Overall, the complete leakage closure rate was 80%, and no significant difference was found between the clipping and stent groups (79.0% vs. 82.6%, respectively; P = 0.89). The complete leakage closure rate was significantly lower in the duodenal and jejunal stump sites (60%) than esophageal sites (86.1%) and gastric sites (94.1%; P = 0.026). The multivariate analysis showed that stump leakage sites (adjusted odds ratio [aOR], 4.51; P = 0.031) and the presence of intra-abdominal abscess (aOR, 4.92; P = -0.025) were associated with unsuccessful leakage closures.ConclusionsEndoscopic therapy using clippings or stents is an effective method for the postoperative management of AL in gastric cancer patients. This therapy can be considered a primary treatment option due to its demonstrated efficacy, safety, and minimally invasive nature.

Direct and two-step single anastomosis duodenal switch (SADI-S): Unicentric comparative analysis of 232 cases

IntroductionThe “Single Anastomosis Duodeno-Ileal bypass with Sleeve gastrectomy” (SADI-S) is a bariatric surgery conceived to simplify the duodenal switch in order to reduce its postoperative complications. The objective of this study is to assess the safety and efficacy of SADI-S, comparing its results in both direct and two-step procedure. MethodsUnicentric cohort study that includes patients submitted to SADI-S, both direct or in two-step, between 2014 and 2019. ResultsTwo hundred thirty-two patients were included, 192 were submitted to direct SADI-S and 40 had previously undergone a sleeve gastrectomy. The severe complications rate (Clavien-Dindo ≥ IIIA) was 7.8%, being hemoperitoneum and duodenal stump leak the most frequent ones. One patient was exitus between the first 90 days after surgery (0.4%). Patients submitted to direct SADI-S had an initial body mass index (BMI) of 49.6 kg/m2 in comparison of 56.2 kg/m2 in the two-step SADI-S (P < .001). The mean excess weight loss (EWL) at two years was higher in direct SADI-S (77.3 vs. 59.3%, P < .05). Rate of comorbidities resolution was 88.5% for diabetes, 73.0% for hypertension, 77.0% for dyslipidemia and 85.7% for sleep apnea, with no differences between both techniques. ConclusionIn medium term, SADI-S is a safe and effective technique that offers a satisfactory weight loss and remission of comorbidities. Patients submitted to two-step SADI-S had a higher initial BMI and presented a lower EWL than direct SADI-S.

A case report of percutaneous direct injection of N-butyl-2-cyanoacrylate (NBCA) to treat a pancreatic duodenal stump leak after a simultaneous pancreas and kidney transplantation

BackgroundSimultaneous pancreas and kidney transplantation (SPK) is a treatment option for patients with end-stage renal disease due to type 1 diabetes mellitus. We report a patient with a refractory fistula due to leakage from the duodenal stump of the pancreas graft after an SPK with bladder drainage who was successfully treated with a percutaneous direct injection of N-butyl-2-cyanoacrylate (NBCA).Case presentationA 60-year-old female with a 33-year history of type 1 diabetes mellitus and a 10-year history of renal replacement therapy underwent an SPK in 2015. At the time of transplantation, an abdominal aortic aneurysm with a high risk of rupture was treated by a Y-graft replacement prior to the SPK. Bladder drainage of the pancreas graft was chosen to avoid a vessel graft infection. The patient’s postoperative course was uneventful. The patient was discharged on postoperative day 93 with good-functioning pancreas and kidney grafts. One and a half years after the operation, the patient was found to have acute graft pancreatitis and a leak from the duodenal stump of the pancreas graft due to a paralytic neurogenic bladder. The insertion of an indwelling catheter into the bladder and the endoscopic-guided insertion of a catheter into the graft pancreatic duct through the duodenum/bladder anastomosis did not result in the closure of the fistula. Therefore, NBCA was injected at the site of the leak point using CT-guided technique. The fistula was completely closed immediately after the injection, with no recurrences of leaks.ConclusionsA percutaneous direct injection of NBCA is one of the treatment options to treat intractable fistulas.

Management of perforated large/giant peptic ulcers: a comparative prospective study between omental plug, duodenal exclusion, and jejunal serosal patch

Background Large/giant peptic ulcer (duodenal ulcer and benign gastric ulcer) perforation is a serious life-threatening surgical emergency, with high morbidity and mortality rates. Despite that, no single surgical approach has yet been shown to be superior to others. Patients and methods This is a prospective randomized study comparing the efficacy of omental plugging, duodenal exclusion, and jejunal serosal patch as different alternating operative techniques in managing such a problem. Results Thirty patients with large/giant peptic perforation more than 2 cm in diameter were included over a period of 24 months. Patients were divided into three groups (A, B, and C) according to surgical approach applied. Males/females were 27/3, average age was 45–73 years old, and mean operative time was 75±28.4 min. Biliary leak rates were 3.3, 10, and 6.6% in group A (omental plug), group B (jejunal serosal patch), and group C (duodenal exclusion and gastrojejunostomy), respectively, with P value of 0.199. Conclusion The management of large/giant peptic (duodenal ulcer and gastric ulcer) perforations is difficult and presents a great challenge to surgeons. Duodenal stump leaks can carry high incidence of morbidity and mortality. Multiple surgical modalities are available to deal with such surgical problems.

Robotic gastric surgery: a monocentric case series and review of the literature.

The technical complexity of D2 lymphadenectomy and esophago-jejunal anastomosis are the main factors that limit the application of laparoscopic surgery in the treatment of gastric cancer. Robotic assisted gastric surgery provides potential technical advantages over conventional laparoscopy but an improvement in clinical outcomes after robotic surgery has not been demonstrated yet. Data from 128 consecutive patients who had undergone robotic gastrectomy for gastric cancer at our center institution from April 2017 to June 2020 where retrospectively reviewed from a prospectively updated database. A narrative review was then carried out on PubMed, Embase and Scopus using the following keywords: "gastric cancer," "robotic surgery," "robotic gastrectomy" and "robotic gastric surgery". Ninety-eight patients underwent robotic distal gastrectomy and 30 underwent robotic total gastrectomy. The mean value of estimated blood loss was 99.5 ml. No patients required conversion to laparoscopy or open surgery. The median number of retrieved lymph nodes was 42. No tumor involvement of the proximal or distal margin was found in any patient. The median time to first flatus and first oral feeding was on postoperative day 3 and 5, respectively. We registered 6 leakages (4.6%), namely, 1 duodenal stump leakage and 5 anastomotic leakages. No 30-day surgical related mortality was recorded. The median length of hospital stay was 10.5 days (range 4-37). Published data and our experience suggest that the robotic approach for gastric cancer is safe and feasible with potential advantages over conventional laparoscopy.

Surgery with hyperthermic intraperitoneal chemotherapy after response to induction chemotherapy in patients with peritoneal metastasis of gastric cancer.

Gastric cancer (GC) with peritoneal metastases (PM) has a dismal prognosis and to date only a few management options have been reported. Of those, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) after induction bidirectional intraperitoneal and systemic chemotherapy (BIPSC) appear as a promising treatment option for these patients. Outcome data including safety and efficacy of CRS with radical Gastrectomy and HIPEC after response to combination of laparoscopic HIPEC (LHIPEC) with BIPSC as an induction therapy in patients with PM of GC was evaluated in this retrospective observational study. Diagnostic Laparoscopy was performed in 53 patients with PM of GC who admitted to the Center for Treatment of Peritoneal Surface Malignancies, Istanbul, between 2013 and 2016. Peritoneal cancer index (PCI), ascites status and cytology were determined. The patients underwent LHIPEC and then, BIPSC induction chemotherapy using intraperitoneal docetaxel (30 mg/m2) and cisplatin (30 mg/m2) and intravenous Docetaxel/Cisplatin/5-Fluorouracil (DCF) for 3 cycles. In selected patients, CRS with radical gastrectomy and HIPEC were performed after the response to induction therapy. BIPSC was continued for 3 more cycles with a dose reduction in an adjuvant setting. All LHIPEC procedures were uneventful with Grade 1-2 side effects (11/53, 20,8%). As a response to induction chemotherapy PCI was reduced from 19.6±8 (range, 6-39) to 13.6±9.8 (range, 1-39) (P<0.001). Ascites was detected in 55% (29 out of 53) and cytology was positive in 51% (27 out of 53) of the patients before induction chemotherapy. Ascites was completely abolished and all cytology became negative. Then, 34 of 53 (64.15%) patients underwent CRS with radical gastrectomy and HIPEC. CC0/1 resection was achieved in 22 (64.70%) of patients (P<0.05). The median survival time was 18.9±13.4 (95% CI: 15.2-22.6 months. Combined surgery and HIPEC related mortality occurred in 1 out of 34 patients (2.9%) due to developed diffuse intravascular coagulation at postoperative day 2. Grade 2 operative complications included biliary fistula in one, and duodenal stump leakage in two patients (8.7%). All of the fistula closed with conservative management. The median survival time was 18.9±13.4 months and the median progression-free survival time was 15.6±12.9 with 1-, 2-, and 5-year survival rates of 82.4%, 59% and 17.6% in patients with PM of GC. Multivariate analysis identified high peritoneal cancer index (P=0.000) and complete resection (P<0.05) as independent predictors for better progression-free and overall survival. The best outcomes can be expected with optimal cytoreduction and limited peritoneal dissemination in response to induction chemotherapy. Knowledgeable selection of patients with PM of GC is essential to perform surgery with HIPEC safely with acceptable mortality and morbidity.

Endoscopic 'suction room' to treat complex enteral stump leaks after upper gastrointestinal surgery.

Leaks/dehiscence of the enteral stump associated with infected peri-enteric collections after upper gastrointestinal surgery are a life-threatening adverse event, not usually endoscopically treatable. We describe a new endoscopic approach to treat complex entero-cutaneous fistulas (CECF) by creating a “suction room” through placement of multiple stents (enteral, biliary and/or pancreatic) and a large nose-enteral suction tube inside the enteral stent maintained on a continuous negative aspiration suction. Between January 2016 and December 2019, six consecutive patients referred to our unit with CECF of the enteral stump after failed redo surgeries underwent creation of a “suction room.” In five patients, enteral, biliary and pancreatic stents were positioned before a nose-to-stent or nose-to-collection large 18 Fr tube placement. In one patient, a pancreatic stent was not placed. Technical and clinical success were achieved in all patients. Mean and median times of aspiration were 49 and 27 days, respectively, with a mean hospital stay of 56 days after the endoscopic procedure. Stents were successfully removed. Mean post-procedural follow-up was 17.3 months. Endoscopic creation of the “suction room” offers the unique possibility of treating complex entero-cutaneous fistulas in surgically altered sites, which are difficult to manage with standard endoscopic methods.

Endoscopic Vacuum Therapy (EVT) for Persistent Duodenal Stump Dehiscence After Upper Gastrointestinal Surgery in Selected Patients: A Tertiary Referral Center Case Series.

The usefulness of endoscopic vacuum therapy (EVT) in the setting of postoperative gastrointestinal leaks is widely described. On this basis, we would like to focus a specific application of EVT: the dehiscence of the duodenal stump after upper gastrointestinal surgery. Standard EVT is not applicable in these cases because of technical limitations (length of overtube and devices). However, vacuum stimulates the healing of leaks and fistulas through granulation tissue's formation and would be effective also in this setting. Between October 2019 and January 2020, 7 consecutive patients (4 M, 3 F, 62±9 y old) affected by duodenal stump's dehiscence were endoscopically treated by the placement of a large-bore (14 to 18 Ch) suction tube across the wall's defect into the peritoneal cavity. Continuous aspiration at -80/-100 mm Hg was applied. Clinical success was established both by fluoroscopic check injecting contrast medium from the tube to verify the fistula's closure and by abdominal computed tomography scan to exclude residual fluid collections. Technical and clinical success were achieved in all the patients. The suction tube was maintained in site for 12±5 days in continuous aspiration. The drainage's output became null in 2±1 days without any intra-abdominal residual fluid collection. The principle of this technique is to let the duodenal walls' stump to collapse on the intraluminal part of the tube (with subsequent mucosal intussusception into the holes of the tube itself) creating a sort of vacuum-packed barrier to interrupt the outflow of enteric materials into the fistula's path. It guarantees the fistula's closure by the gradual formation of granulation tissue. The present technique offers a safe and viable endoscopic alternative to treat duodenal stump's leaks after upper gastrointestinal surgery.

Impact of the COVID-19 pandemic on appendicitis treatment in Germany-a population-based analysis.

PurposeAcute appendicitis is one of the most common reasons for emergency medical consultation. While simple appendicitis can be treated with antibiotics or surgery, complex appendicitis including gangrene, abscess, and perforation requires appendectomy. During the COVID-19 pandemic in early 2020, an overall drop in emergency room consultations was observed. We therefore aimed to investigate the incidence and treatment strategies of acute appendicitis during that period.MethodsData of insurance holders with the ICD code for “acute appendicitis” or OPS procedure of appendectomy of a major health insurance company in Germany were analyzed retrospectively. Groups were built, containing of the means of March–June of 2017, 2018, and 2019, defined as “pre-COVID group” with the “COVID group,” defined as data from March to June of 2020. Data was analyzed by age, sex, comorbidities, length of hospital stay, diagnoses, and treatment. Data of the COVID group was analyzed for simultaneous COVID-19 infection.ResultsDuring the COVID-19 pandemic of early 2020, an overall reduction by 12.9% of patients presenting with acute appendicitis was noticeable. These results were mainly due to decreased rates of uncomplicated appendicitis, while complicated appendicitis was scarcely affected. Especially in the group of females < 40 years, a drastic reduction was visible. Rates of extended surgery did not change. Likewise, the complication rate like appendix stump leakage or need for re-operation did not differ. In March 2020, 4.8% of acute appendicitis patients had concomitant COVID-19 infection.ConclusionIn line with the overall drop of emergency room visits during the COVID-19 pandemic of spring 2020 in Germany, a significantly lowered number of patients with uncomplicated appendicitis were noticeable, whereas complicated appendicitis did not differ. Also, treatment and complication rate of acute appendicitis did not change. These findings might be a hint that acute appendicitis is not a progressing disease but caused by different entities for uncomplicated and complicated appendicitis and therefore another clue that uncomplicated appendicitis can be treated with antibiotics or observation. Nevertheless provided data does not cover outpatient treatment; therefore, no statement observation or antibiotics in outpatients can be made.

Surgical Management of Sectoral Bile Duct Injury after Cholecystectomy - A Case Series

Introduction: Injuries to segmental or sectoral bile ducts are encountered less commonly than main bile duct injuries and present a unique diagnostic and therapeutic challenge. Methods: This retrospective study was conducted and data of patients who underwent surgery for sectoral bile duct injury were retrieved from January 2014 to December 2019. Results: Four patients were analyzed. All four were females with mean age of 36.5 years. Two of the four patients had undergone an open cholecystectomy, whereas the remaining two patients had undergone a laparoscopic cholecystectomy. The clinical presentation was external biliary fistula in two and another two patients presented with Pain and fever. Two patients without biliary fistula had late presentation at 2 year and 6 year respectively after index surgery. Two patients had undergone endoscopic retrograde cholangiography (ERCP), the result of ERCP had been interpreted as normal with no leak in one patient, and cystic stump leak in one patient. All patient had undergone magnetic resonance cholangiopancreatography (MRCP). Two of the four patient had right posterior sectoral duct injury and one patient had right anterior sectoral duct injury, one patient had stricture involving right hepatic duct leading to disconnection from common hepatic duct. All patients underwent Roux- en -Y cholangiojejunostomy. At mean follow up of 27 months (range 4 to 68 months) all patients are asymptomatic. Conclusion: Segmental/sectoral bile duct injury should always be suspected and looked for if a biliary leak following cholecystectomy persists. Surgical treatment for this type of lesions, generally results in a favorable outcome.

Management of gastrojejunostomy leakage after emergency gastrectomy

Ulcer perforation remains a life-threatening disease, which can be treated in several surgical approaches, however in some cases an emergency gastrectomy is the only option. Emergency gastrectomy has been associated to high morbidity and local mortality rates, namely systemic complications, such as, duodenal stump leak, gastrojejunostomy leakage and intra-abdominal collections. The treatment of gastrojejunostomy leakage, is still generating controversy, despite nowadays, the conservative approach is preferred. We present a clinical case of a 62-years-old male patient, in which a gastrojejunal leakage occurred, after emergency gastrectomy due to an ulcer perforation. Computed tomography of the abdomen did reveal peritoneal liquid near duodenal stump and gastrojejunostomy with no oral extravasation. At 24th post-operatory day, the patient deteriorated and we decided to perform a laparotomy exploration. Identified and treated, 2 small leakages (6 mm each), on the anterior face of the gastrojejunal anastomosis, using directed fistulization with Pezzer catheters. The patient was kept under total parenteral nutrition followed by enteral feeding and anti-microbial therapeutic. At the consultation, Radiography with oral contrast and Computed Tomography Scan with intravenous and oral contrast showed no evidence of anastomotic leak or abscesses, showing the success of this therapeutic approach.

Endoscopic vacuum therapy for in- and outpatient treatment of colorectal defects

BackgroundEvidence for endoscopic vacuum therapy (EVT) for colorectal defects is still based on small patient series from various institutions, employing different treatment algorithms and methods. As EVT was invented at our institution 20 years ago, the aim was to report the efficacy and safety of EVT for colorectal defects as well as to analyze factors associated with efficacy, therapy duration, and outpatient treatment.MethodsCohort study with analysis of prospectively collected data of patients receiving EVT for colorectal defects at a tertiary referral center in Germany (n = 281).ResultsThe majority of patients had malignant disease (83%) and an American Society of Anesthesiologists classification of III/IV (81%). Most frequent indications for EVT were anastomotic leakage after sigmoid or rectal resection (67%) followed by rectal stump leakage (20%). EVT was successful in 256 out of 281 patients (91%). EVT following multi-visceral resection (P = 0.037) and recent surgical revision after primary surgery (P = 0.009) were risk factors for EVT failure. EVT-associated adverse events occurred in 27 patients (10%). Median treatment duration was 25 days. Previous chemo-radiation (P = 0.006) was associated with a significant longer duration of EVT. Outpatient treatment was conducted in 49% of patients with a median hospital stay reduction of 15 days and 98% treatment success. Younger patient age (P = 0.044) was associated with the possibility of outpatient treatment. Restoration of intestinal continuity was achieved in 60% of patients where technically possible with a 12-month rate of 52%.ConclusionsIn patients with colorectal defects, EVT appears to be a safe and effective, minimally invasive option for in- and outpatient treatment.

Cruce duodenal de una anastomosis (SADI-S) en uno o dos tiempos: análisis comparativo de 232 casos de un solo centro

IntroductionThe «Single Anastomosis Duodeno-Ileal bypass with Sleeve gastrectomy» (SADI-S) is a bariatric surgery conceived to simplify the duodenal switch in order to reduce its postoperative complications. The objective of this study is to assess the safety and efficacy of SADI-S, comparing its results in both direct and two-step procedure. MethodsUnicentric cohort study that includes patients submitted to SADI-S, both direct or in two-step, between 2014 and 2019. ResultsTwo hundred thirty-two patients were included, 192 were submitted to direct SADI-S and 40 had previously undergone a sleeve gastrectomy. The severe complications rate (Clavien-Dindo ≥ IIIA) was 7.8%, being hemoperitoneum and duodenal stump leak the most frequent ones. One patient was exitus between the first 90 days after surgery (0.4%). Patients submitted to direct SADI-S had an initial body mass index (BMI) of 49.6 kg/m2 in comparison of 56.2 kg/m2 in the two-step SADI-S (p < 0.001). The mean excess weight loss (EWL) at two years was higher in direct SADI-S (77.3 vs. 59.3%, p < 0.05). Rate of comorbidities resolution was 88.5% for diabetes, 73.0% for hypertension, 77.0% for dyslipidemia and 85.7% for sleep apnea, with no differences between both techniques. ConclusionIn medium term, SADI-S is a safe and effective technique that offers a satisfactory weight loss and remission of comorbidities. Patients submitted to two-step SADI-S had a higher initial BMI and presented a lower EWL than direct SADI-S.

A Prospective Study Comparing Appendiceal Stump Closure Techniques with Liga Clips v/s Hem-o-Lok in Laparoscopic Appendectomy: Our Experience at a Single Institute

Closure of appendiceal stump (CAS) is one of the most crucial steps in laparoscopic appendectomy (LA) because inappropriate closure of stump may lead to stump leak further causing life-threatening complications like enterocutaneous fistulas, postoperative peritonitis, and sepsis. Recent studies have established the use of endoclips to be simpler and quicker as special laparoscopic skills are not required and hence seamlessly adapted. This study further aimed to compare the results of application endoclips like Liga Clips and Hem-o-Lok for CAS in LA in cases of Appendicitis without complications. It is a prospective study with sixty patients diagnosed with appendicitis without complications and planned for LA in a single institute. They were randomly divided into two groups, A and B, of 30 each using the sequentially numbered opaque sealed envelope (SNOSE) method. Liga Clips were used for CAS in group A and Hem-o-Lok in group B. Operative time and intraoperative and postoperative events were recorded. The mean operative time (time from skeletonization of appendix to retrieval of the appendix) in group A was noted to be 376.03 s (6.27 min) and that in group B was noted to be 345.50 s (5.75 min) (p = 0.2873). No patient developed stump leak or intra-abdominal abscess or had to undergo reoperation in either of the groups. In conclusion, the use of both endoclips like Liga Clips and Hem-o-Lok for closure of appendiceal stump in laparoscopic appendectomy is a quicker, safe, secure, and feasible technique in cases of appendicitis without increased risk of complications. In our experience, it is suggested that Hem-o-Lok is more efficient in securing the appendiceal stump due to its lock engagement system giving a sense of security and ease of application.

Uncut Roux-en-Y gastrojejunostomy after totally laparoscopic distal gastrectomy: Learning curve and surgical outcomes.

Totally laparoscopic distal gastrectomy (TLDG) is now widely used for early gastric cancer patients, but the selection of a reconstruction method after TLDG is still controversial. Roux-en-Y gastrojejunostomy is increasingly used in expectation of less gastritis and alkaline reflux despite its technical difficulty. The uncut Roux-en-Y gastrojejunostomy (uRYGJ) retains the advantages of Roux-en-Y reconstruction but helps prevent Roux stasis syndrome. The present study aims to introduce a single surgeon's experience of TLDG with uRYGJ and analyze the learning curve and surgical outcomes. We retrospectively reviewed the medical records of 124 consecutive patients who underwent TLDG with uRYGJ performed by a single surgeon between July 2014 and August 2015 at Asan Medical Center. The baseline characteristics and surgical outcomes were analyzed, and the learning curve was drawn based on the power-law model. The mean total operative time was 165 minutes, and the average length of hospital stay was 6.6 days. Complications included two cases of duodenal stump leakage, two intra-abdominal bleeding, two intra-abdominal fluid collection, one wound problem, two anastomotic strictures, 14 ileus, and no anastomotic leakage. There were five cases of endoscopically proven reflux gastritis/esophagitis and no Roux stasis syndrome. There were five recurrences and one mortality during the follow-up period. The learning curve leveled at the 15th case. The results of our study showed the safety and feasibility of uRYGJ, and that the technical difficulty of the procedure can be overcome with a short learning curve for experienced surgeons.

PILGRIM: Phase III clinical trial in evaluating the role of hyperthermic intraperitoneal chemotherapy for locally advanced gastric cancer patients after radical gastrectomy with D2 lymphadenectomy(HIPEC-01).

4538 Background: Gastric cancer remains the 3rd leading cancer related death worldwide due to early disease recurrence. We hypothesize that hyperthermic intraperitoneal chemotherapy (HIPEC) may effectively prevent local regional recurrence for locally advanced gastric cancer patients who received curative intent surgery. Methods: Pathology proven gastric cancer patients with clinical T3/T4NxM0 disease are eligible for the study and will be randomized to either control group, who will receive standard radical gastrectomy and D2 lymph node dissection or HIPEC group, who will receive the same surgery and HIPEC with paclitaxel x 2 within the first week after surgery. All patients will receive either XELOX or SOX adjuvant chemotherapy. The primary end point is overall survival. Results: 648 patients from 16 high volume gastric medical centers were enrolled between May, 2015 and March, 2019. 331 and 317 patients were randomized to control and HIPEC groups respectively. The median follow-up time is 12.1 months. The common grade 3/4 toxicities ( &gt; 5%) in control and HIPEC groups are anemia 6% vs. 4.1%, intraabdominal infection 5.4% vs. 3.8%, pneumonia 9.7% vs. 9.8%, fever 10.6% vs. 11.4% and hypoalbunemia 15.1% vs. 16.7% respectively. All three perioperative death (within 30 days after surgery) occurred in control group. One patient died from duodenum stump leak which led to multiple organ failure. One patient died from anastomotic led to intraabdominal infection and shock. The 3rd death was suicide caused by severe depression. At the time of this report, the number of event has not reached for final efficacy analysis. Conclusions: It is safe to administer HIPEC to patients received radical gastrectomy with D2 lymph node dissection within one week of surgery. The primary analysis will be expected in one year. Clinical trial information: NCT02356276 .
