Cholecystocolic fistula (CCF) is a rare and late complication of gallbladder disease. The cause of CCF is known to be peptic ulcer, gallbladder disease, malignant tumor, trauma, and postoperative complications. The proper treatment method is to perform cholecystectomy and to identify and alleviate the CCF. However, cholecystectomy is not always possible owing to technical difficulties and disease severity. CCF is difficult to diagnose preoperatively, and CCF operation without an accurate preoperative diagnosis can lead to a more complicated surgery and cause surgeons to face more difficult situations or to endanger patients' lives. We report a case of asymptomatic CCF successfully treated with laparoscopic surgery after accurate diagnosis before surgery.

PURPOSE: Laparoscopic cholecystectomy is treatment method for management of benign gallbladder diseases. Further attempts are made to operate single-port laparoscopic cholecystectomy. However, single-port laparoscopic cholecystectomy, the procedure remains technically difficult, especially in obese patient. Recently, a robotic surgical system for minimal invasive surgery was introduced to overcome the limitations of conventional laparoscopic surgery. METHODS: From April 2009 to August 2017, we retrospectively reviewed the medical records of patients with single-site, minimally invasive (laparoscopic and robotic) cholecystectomy with high BMI (>25 kg/m2). We analyzed general characteristics and perioperative outcomes between the single-fulcrum laparoscopic cholecystectomy group and the robotic single-site cholecystectomy (RSSC) group. RESULTS: Operation time (57.56±11.10 vs 98.5±12.28 p<0.001) was significantly longer and postoperative pain score (3.61 vs 5.15 p=0.000) was significantly higher in the robotic single-site cholecystectomy (RSSC) group, but the actual dissection time (25.85±11.09 vs 25.79±13.35 p=0.978) was not significantly different between the two approaches. Iatrogenic gallbladder perforation, (13 vs 6 p=0.005), patients undergoing RSSC showed a significantly smaller amount than did those undergoing single-fulcrum laparoscopic cholecystectomy (SFLC). CONCLUSION: It is difficult to say for certain that RSSC is clearly better than SFLC in obese patients. However, because of the technical convenience and efficiency of surgery with RSSC, RSSC can be practically worthwhile. Further study is mandatory.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) is a surgical method to treat gallbladder disease designed to reduce postoperative pain and improve cosmetic results. However, pure SILC (pSILC) has several inherent limitations. In this study, we report the surgical outcomes of SILC with needlescopic grasper (nSILC) compared with those of pSILC and conventional three-port laparoscopic cholecystectomy (TPLC).METHODS: This retrospective study enrolled 103 patients who underwent laparoscopic cholecystectomy for benign gallbladder disease in our hospital between January 2013 and January 2015. Among them, 33 patients underwent pSILC, 35 underwent nSILC, and 35 underwent TPLC. We collected demographic characteristics and operative data to analyze outcomes between groups.RESULTS: All procedures were done by laparoscopy and the gallbladder of each patient was completely removed. Women and younger patients were more to undergo SILC than TPLC. Analysis showed that the operation time of the nSILC group was longer than that of the TPLC group, but shorter than that of the pSILC group (skin to skin operation time [pSILC: 65.2±19.1 min, nSILC: 49.7±12.9 min, and TPLC: 43.4±14.7 min, p<0.001], and major procedure time [pSILC: 42.2±18.7 min, nSILC: 25.9±8.9 min, and TPLC: 23.4±12.7 min, p<0.001]). There were no significant differences between the groups for patient visual analogue scale score, length of hospital stay, or intraoperative blood loss.CONCLUSION: nSILC is feasible surgical method in patients with benign gallbladder disease compared to TPLC, and that is an effective procedure to overcome the disadvantage of pSILC.

BACKGROUND: With the popularity of laparoscopic cholecystectomy, common bile duct injury has been reported more frequently. There is no perfect method for repairing porcine biliary segmental defects.METHODS: After the decellularization of human arterial blood vessels, the cells were cultured with GFP⁺ (carry green fluorescent protein) porcine bile duct epithelial cells. The growth and proliferation of porcine bile duct epithelial cells on the human acellular arterial matrix (HAAM) were observed by hematoxylin-eosin (HE) staining, electron microscopy, and immunofluorescence. Then, the recellularized human acellular arterial matrix (RHAAM) was used to repair biliary segmental defects in the pig. The feasibility of it was detected by magnetic resonance cholangiopancreatography, liver function and blood routine changes, HE staining, immunofluorescence, real-time quantitative PCR (RT-qPCR), and western blot.RESULTS: After 4 weeks (w) of co-culture of HAAM and GFP? porcine bile duct epithelial cells, GFP⁺ porcine bile duct epithelial cells grew stably, proliferated, and fused on HAAM. Bile was successfully drained into the duodenum without bile leakage or biliary obstruction. Immunofluorescence detection showed that GFP-positive bile duct cells could still be detected after GFP-containing bile duct cells were implanted into the acellular arterial matrix for 8 w. The implanted bile duct cells can successfully resist bile invasion and protect the acellular arterial matrix until the newborn bile duct is formed.CONCLUSION: The RHAAM can be used to repair biliary segmental defects in pigs, which provides a new idea for the clinical treatment of common bile duct injury.

Laparoscopic cholecystectomy is a widely used treatment method for most cholelithiasis and is a relatively safe procedure. Foreign body granulomatous reaction to bile or gallstone spillage during laparoscopic cholecystectomy has rarely been reported. We report a case of bile granuloma after laparoscopic cholecystectomy, which mimicked peritoneal seeding. A 59-year-old Korean man presented with right upper quadrant pain. He underwent laparoscopic cholecystectomy for acute cholecystitis with cholelithiasis. Pathologic examination revealed an incidental adenocarcinoma invading the lamina propria with acute cholecystitis and cholelithiasis. After 3 months, follow-up abdominal computed tomography revealed a subhepatic nodule, which showed hypermetabolism on positron emission tomography–computed tomography. Suspecting localized peritoneal seeding, wedge resection of the liver, wedge resection of the transverse colon, and omentectomy were performed. Pathologic examination of the resected specimens revealed multiple bile granulomas. Awareness of bile granuloma mimicking malignancy is noteworthy for patient management to reduce unnecessary procedure during postoperative surveillance.

Situs inversus totalis (SIT) is a rare condition in which the viscera are transposed in a mirror image reversal. We report two cases of laparoscopic cholecystectomy (LC) performed for SIT patients. A 63-year old male patient with SIT was diagnosed with symptomatic gallstones. We performed LC by 3-port method. The patient was discharged uneventfully on postoperative day 2. A 57-year old female patient with SIT underwent LC for acute cholecystitis. Due to severe inflammation an assistant was needed. The patient was discharged uneventfully on postoperative day 3. Over 80 cases of LCs in SIT patients have been reported so far and LC has become the standard treatment. The current report confirms the safety of laparoscopy in such cases. Laparoscopic cholecystectomy can be performed safely in SIT patients if care is taken. Surgeons need to be careful of reversed anatomy and unaccustomed working hand.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) is increasingly performed worldwide. Accordingly, the Konyang Standard Method (KSM) for SILC has been developed over the past 6 years. We report the outcomes of our procedures. METHODS: Between April 2010 and December 2016, 1,005 patients underwent SILC at Konyang University Hospital. Initially 3-channel SILC with KSM was changed to 4-channel SILC using a modified technique with a snake retractor for exposure of Calot triangle; we called this a modified KSM (mKSM). Recently, we have used a commercial 4-channel (Glove) port for simplicity. RESULTS: SILC was performed in 323 patients with the KSM, in 645 with the mKSM, and in 37 with the commercial 4-channel port. Age was not significantly different between the 3 groups (P = 0.942). The postoperative hospital days (P = 0.051), operative time (P < 0.001) and intraoperative bleeding volume (P < 0.001) were significantly improved in the 3 groups. Drain insertion (P = 0.214), additional port insertion (P = 0.639), and postoperative complications (P = 0.608) were not significantly different in all groups. Postoperative complications were evaluated with the Clavien-Dindo classification. There were 3 cases (0.9%) over grade IIIb (bile duct injury, incisional hernia, duodenal perforation, or small bowel injury) with KSM and 3 (0.5%) with mKSM. CONCLUSION: We evaluated the evolution of the KSM for SILC. The use of the mKSM with a commercial 4-channel port may be the safest and most effective method for SILC.

PURPOSE: Robotic-associated minimally invasive surgery is a novel method for overcoming some limitations of laparoscopic surgery. This study aimed to evaluate the outcomes (postoperative pain, cosmesis, surgeon's workload) of single-incision robotic cholecystectomy (SIRC) vs. single-incision laparoscopic cholecystectomy (SILC) vs. conventional three-port laparoscopic cholecystectomy (3PLC). METHODS: 134 patients who underwent laparoscopic or robotic cholecystectomy at a single center during 2016~2017 were enrolled. Prospectively collected data included demographics, operative outcomes, questionnaire regarding pain and cosmesis, and NASA-Task Load Index (NASA-TLX) scores for surgeon's workload. RESULTS: 55 patients underwent SIRC, 29 SILC, and 50 3PLC during the same period. 3PLC patient group was older than the others (SIRC vs. SILC vs. 3PLC: 48.1 vs. 42.2 vs. 54.1 years, p < 0.001). Operative time was shortest with 3PLC (44.1 vs. 38.8 vs. 25.4 min, p < 0.001). Estimated blood loss, postoperative complications, and postoperative stay were similar among the groups. Pain control was lowest in the 3PLC group (98.2% vs. 100% vs. 84.0%, p=0.004), however, at 2 weeks postoperatively there were no differences among the groups (p=0.374). Cosmesis scores were also worst after 3PLC (17.5 vs. 18.4 vs. 13.3, p < 0.001). NASA-TLX score was highest in the SILC group (21.9 vs. 44.3 vs. 25.2, p < 0.001). CONCLUSION: Although SIRC and SILC take longer than 3PLC, they produce superior cosmetic outcomes. Compared with SILC, SIRC is more ergonomic, lowering the surgeon's workload. Despite of higher cost, SIRC could be an alternative for treating gallbladder disease in selected patients.

PURPOSE: The average rate of surgical site infections (SSIs) for laparoscopic cholecystectomy (LC) has been reported in the literature to be between 0.4% and 6.3%. Also, these recent reviews have concluded that a prophylactic antibiotics for elective LCs in low-risk patients is not useful, but there were no results in high-risk patients. METHODS: The aim of this study was to investigate the role of a single dose of first-generation cephalosporin as a prophylactic antibiotic for patients undergoing elective LC, regardless of patient risk. This randomized clinical trial was conducted from October 2013 to December 2014 by single surgeon at our hospital. Patients were randomized into two groups by following method. Odd-numbered patients (group A) received 1-g cefazolin intravenously within 30 minutes before incision, whereas even-numbered patients (group B) received normal saline intravenously instead of prophylactic antibiotics, with the aim of including 100 patients in each group. SSIs were recorded and compared between the groups. RESULTS: There were no differences in preoperative demographics and postoperative findings between the groups. There were no superficial and deep SSIs in either group, 9 cases of superficial seromas developed (4.5%) in the cohort: 4 in group A (4%) and 5 in group B (5%). There were no significant associations between SSIs and the use of prophylactic antibiotics in either group. Additionally, the high-risk group did not show a significantly increased rate of SSIs. CONCLUSION: Based on our study, prophylactic antibiotics are not necessary in elective LC, regardless of patient risk.
