PURPOSE: To assess the feasibility of transanal total mesorectal excision in difficult cases including obese patients or patients with bulky tumors or threatened mesorectal fascias. METHODS: We performed laparoscopy-assisted transanal total mesorectal excision in patients with biopsy-proven rectal adenocarcinoma located 3–12 cm from the anal verge as part of a prospective, single arm, pilot trial. The primary endpoint was resection quality and circumferential resection margin involvement. Secondary endpoints included the number of harvested lymph nodes and 30-day postoperative complications. RESULTS: A total of 12 patients (9 men and 3 women) were enrolled: one obese patient, 7 with large tumors and 8 with threatened mesorectal fascias (4 patients had multiple indications). Tumors were located a median of 5.5 cm from the anal verge, and all patients received preoperative chemoradiotherapy. Median operating time was 191 minutes, and there were no intraoperative complications. One patient needed conversion to open surgery for ureterocystostomy after en bloc resection. Complete or near-complete excision and negative circumferential resection margins were achieved in all cases. The median number of harvested lymph nodes was 15.5. There was no postoperative mortality and 3 cases of postoperative morbidity (1 postoperative ileus, 1 wound problem near the stoma site, and 1 anastomotic dehiscence). CONCLUSION: This pilot study showed that transanal total mesorectal excision is also feasible in difficult laparoscopic cases such as in obese patients or those with bulky tumors or tumors threatening the mesorectal fascia. Additional larger studies are needed.

BACKGROUND: Although intravenous (i.v.) lidocaine is used as a perioperative analgesic in abdominal surgery, evidence of efficacy is limited. The infusion dose and duration remain unclear. This study aimed to investigate the effect of a longer low-dose 48-hour infusion regimen on these outcomes. METHODS: Fifty-eight adults undergoing elective open colorectal surgery were randomized into the lidocaine group (1.5 mg/kg bolus followed by 1 mg/kg/h infusion for 48 hours) and control group. After surgery, patients were given a fentanyl patient-controlled analgesia machine and time to first bowel movement (primary outcome) and flatus were recorded. Postoperative pain scores and fentanyl consumption were assessed for 72 hours. RESULTS: There was no significant difference in time to first bowel movement (80.1 ± 42.2 vs. 82.5 ± 40.4 hours; P = 0.830), time to first flatus (64.7 ± 38.5 vs. 70.0 ± 31.2 hours; P = 0.568), length of hospital stay (9 [8–13] vs. 11 [9–14) days; P = 0.531], nor postoperative pain scores in the lidocaine vs. control groups. Cumulative opioid consumption was significantly lower in the lidocaine vs. the control group from 24 hours onwards. At 72 hours, cumulative opioid consumption (µg fentanyl) in the lidocaine group (1,570 [825–3,587]) was over 40% lower than in the placebo group (2,730 [1,778–5,327]; P = 0.039). CONCLUSIONS: A 48-hour low-dose i.v. lidocaine infusion does not significantly speed the return of bowel function in patients undergoing elective open colorectal surgery. It was associated with reduced postoperative opioid consumption, but not with earlier hospital discharge, or lower pain scores.

OBJECTIVETo investigate the risk factors of prolonged postoperative ileus (PPOI) after gastric cancer surgery.

METHODSDefinition of PPOI was that gastrointestinal function did not return to normal within 96 hours after operation. Diagnostic criteria of PPOI were as follows: according with over 2 below conditions at postoperative 97-hour: (1) moderate to severe sick (mild: 1-3 points, moderate: 4-7 points, severe: 8-10 points) or vomiting occurred in past 12 hours. (2) patient was intolerable of solid food in the last 2 meals and reported the food-intake as less than 25%. (3) no flatus and defecation occurred in past 24 hours. (4) moderate to severe abdominal distension was diagnosed by doctor with knocking abdomen. (5) iconography examination (abdominal X-ray or CT) in past 24 hours revealed gastrectasis, gas-fluid plane, intestinal or colorectal loop extension, indicating the ileus. A total of 83 patients with gastric carcinoma confirmed by preoperative gastroscopic pathology undergoing operation at the Department of General Surgery, Chinese PLA General Hospital from August 2016 to October 2016 were prospectively enrolled in the study. The incidence and risk factors of PPOI after gastric cancer surgery were calculated and analyzed with univariate and logistic regression multivariate analyses.

RESULTSOf 83 gastric cancer patients, 62 were male and 21 were female with an average age of (60.1±11.0)(39-89) years. Postoperative pathology showed 41 cases with III(-IIII( stage, 42 cases with I(-II( stage. According to the above diaguostic criteria, 22(26.5%) patients were diagnosed as PPOI postoperatively. Among 22 cases, 3 cases had no flatus and defecation with moderate-severe sick and vomiting within postoperative 96 hours; 15 cases had no flatus and defecation with moderate-severe abdominal extension within postoperative 96 hours; 4 cases had no flatus and defecation with moderate-severe sick, vomiting and moderate-severe abdominal extension within postoperative 96 hours. Clinical symptoms of all the POOI patients were improved following conservative treatment. Univariate analysis showed that age ≥65 years[13/26(50.0%) vs. 9/57(15.8%), χ=10.727, P=0.001], postoperative body temperature ≥38.0centi-degree [8/17(47.1%) vs. 14/66(21.2%), χ=4.636, P=0.031], postoperative serum potassium level[20/81(24.7%) vs. 2/2, χ=5.682, P=0.017], and use of opioid agent Dezocine [15/38(39.5%) vs. 7/45(15.6%), χ=6.050, P=0.014] were associated with POOI. Logistic regression analysis showed that age ≥65 years (OR=17.415, 95%CI:17.151-17.750, P=0.015), postoperative body temperature ≥38centi-degree(OR=15.855, 95%CI:15.422-16.214, P=0.013), use of Dezocine after surgery (OR=21.379, 95%CI:20.814-21.654, P=0.010) were the independent risk factors of PPOI after gastric cancer surgery.

CONCLUSIONGastric patients with older age, increased body temperature and the use of Dezocine after surgery have higher risk of POOI and need special perioperative management and treatment.

OBJECTIVETo explore the safety and feasibility of the combined medial and caudal approach in laparoscopic D3 lymphadenectomy plus complete mesocolic excision(CME) for right hemicolectomy in the treatment of right hemicolon cancer complicated with incomplete ileus.

METHODSClinical data of 65 patients with incomplete obstructive right-sided colon cancer (T1 to 4M0) diagnosed by abdominal CT enhanced scan or MRI and/or electric colonscope undergoing laparoscopic right hemicolectomy (D3 lymphadenectomy + CME) at Department of Emergency Medicine and Department of Gastrointestinal Surgery from June 2014 to June 2017 were retrospectively analyzed. Among them, 33 patients received the combined medial and caudal approach (combined medial and caudal approach group) and the other 32 patients received the cephalo medial-to-lateral approach (cephalo medial-to-lateral approach group). The operation highlights of the combined medial and caudal approach group were as follows: (1) The superior mesenteric vein (SMV) was first identified and exposed using the combined medial and caudal approach, and lymph node dissection along the anterior and right of SMV was performed. (2) With horizontal part of duodenum as landmarks, the dorsal mesenteric membrane of terminal ileum was opened by caudal-to-cranial approach, and right retroperitoneal space along the Toldt's space was separated. The anterior of pancreatic head and the right Toldt's space were then exposed. (3) Finally using medial-to-lateral approach, the roots of ileocolic vessels, middle colic vessel and right colic vessel were disconnected and ligated along the left border of SMV. The right branch of gastrocolic trunk of Henle was ligated and lymph node dissection along SMV was performed again. Patients in cephalo medial-to-lateral approach group underwent conventional operation. Baseline information, intraoperative blood loss, operation time, number of harvested lymph nodes, proportion of no less than 12 harvested lymph nodes per case, postoperative hospital stay and postoperative morbidity in both groups were analyzed and compared.

RESULTSThirty-eight males and 27 females with age of 31 to 72 (56.8±11.7) years were enrolled in this study. There was no significant difference in baseline information between combined medial and caudal approach group and cephalo medial-to-lateral approach group(all P>0.05). Intraoperative blood loss [(106.5±24.5) ml vs. (308.4±27.1) ml, t=-31.501, P=0.000] was significantly less, and operative time [(176.3 ± 18.0) minutes vs. (208.4 ± 47.3) minutes, t=-3.602, P=0.001] was significantly shorter in the combined medial and caudal approach group. The proportion of no less than 2 harvested lymph nodes per case [87.9%(29/33) vs. 84.4%(27/32)], the number of harvested lymph nodes (22.5±8.9 vs. 21.5± 7.6), postoperative morbidity of complication [6.1%(2/33) vs. 12.5%(4/32)] and postoperative hospital stay [(11.9±1.5) days vs. (13.4±4.4) days] were not significantly different between the two groups(all P>0.05).

CONCLUSIONThe combined medial and caudal approach in laparoscopic right hemicolectomy (D3+CME) in the treatment of incomplete obstructive right-sided colon cancer is safe and feasible, and has advantages of less intraoperative blood loss and shorter operation time compared to the cephalo medial-to-lateral approach.

PURPOSE: To evaluate the feasibility of transanal total mesorectal excision (TME) in patients with rectal cancer. METHODS: This study enrolled 12 patients with clinically node negative rectal cancer located 4–12 cm from the anal verge who underwent transanal endoscopic TME with the assistance of single port laparoscopic surgery between September 2013 and August 2014. The primary endpoint was TME quality; secondary endpoints included number of harvested lymph nodes and postoperative complications within 30 days (NCT01938027). RESULTS: The 12 patients included 7 males and 5 females, of median age 59 years and median body mass index 24.2 kg/m². Tumors were located on average 6.7 cm from the anal verge. Four patients (33.3%) received preoperative chemoradiotherapy. Median operating time was 195 minutes and median blood loss was 50 mL. There were no intraoperative complications and no conversions to open surgery. TME was complete or nearly complete in 11 patients (91.7%). Median distal resection and circumferential resection margins were 18.5 mm and 10 mm, respectively. Median number of harvested lymph nodes was 15. Median length of hospital stay was 9 days. There were no postoperative deaths. Six patients experienced minor postoperative complications, including urinary dysfunction in 2, transient ileus in 3, and wound abscess in 1. CONCLUSION: This pilot study showed that high-quality TME was possible in most patients without serious complications. Transanal TME for patients with rectal cancer may be feasible and safe, but further investigations are necessary to evaluate its long-term functional and oncologic outcomes and to clarify its indications.

OBJECTIVETo explore the feasibility and safety of Bishop-Koop stoma procedure in the treatment of neonates with refractory congenital intestinal atresia.

METHODSClinical and follow-up data of 25 neonates with refractory congenital intestinal atresia undergoing Bishop-Koop stoma procedure in our center from January 2011 to December 2014 were retrospectively analyzed. Of 25 neonates, 13 (52%) were male, 12(48%) were female, the birth weight was 1600-3800 g (mean 2920 g), the age of admission was 10 hours to 20 days, and the age of operation was 1-58 d (mean 7 d). Diameter ratio of proximal atresia intestine to distal atresia intestine was all greater than 4. Eleven cases(44%) were high jejunal atresia, 3 cases(12%) type III( b, 7 cases(28%) type IIII(, 14 cases(56%) were identified as complex meconium peritonitis, and 3 cases (12%) received reoperation.

RESULTSAll the cases completed their Bishop-Koop stoma operations successfully with median operative time of 3 (1.2-4.5) hours and median intra-operative blood loss of 3.5(1-18) ml. The postoperative complication rate was 20%(5/25), including 3 cases of cholestasis, 1 case of ileus, and 1 case of neonatal necrotizing enterocolitis with septicemia who died 6 days after operation resulting in the mortality of 4%. Besides, 1 case gave up treatment because of economic reason. For the rest 23 neonates, the median first feeding time was 11 days and mean time was 11(5 to 20) days; the median time of postoperative total parenteral nutrition (TPN) was 15 days and mean time was 21 (5 to 68) days; the median hospital stay was 33 days and mean hospital stay was 25(12 to 81) days, respectively. Two-stage stoma closure operations were performed in all the 23 cases afterwards and no postoperative associated complications were found. When discharge after Bishop-Koop stoma operations, Z score of body weight was normal in 3 cases(13.0%) and lower than normal in 20 cases(87.0%), while in hospitalization for stoma closure, Z score of body weight was normal in 19 cases(82.6%) and lower than normal in 4 cases (17.4%). Of 23 cases, serum albumin level was normal in 9 cases(39.1%) before operation, in 3 cases (13.0%) when discharge and in 22 cases(95.7%) in hospitalization for stoma closure.

CONCLUSIONBishop-Koop stoma procedure is safe and feasible in the treatment of neonates with refractory congenital intestinal atresia, and can obviously improve the nutritional status.

PURPOSE: Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. MATERIALS AND METHODS: From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. RESULTS: Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. CONCLUSION: Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit.

PURPOSE: The aim of this study is to describe our initial experience and assess the feasibility and safety of robotic and laparoscopic lateral pelvic node dissection (LPND) in advanced rectal cancer. METHODS: Between November 2007 and November 2012, extended minimally invasive surgery for LPND was performed in 21 selected patients with advanced rectal cancer, including 11 patients who underwent robotic LPND and 10 who underwent laparoscopic LPND. Extended lymphadenectomy was performed when LPN metastasis was suspected on preoperative magnetic resonance imaging even after chemoradiation. RESULTS: All 21 procedures were technically successful without the need for conversion to open surgery. The median operation time was 396 minutes (range, 170-581 minutes) and estimated blood loss was 200 mL (range, 50-700 mL). The median length of stay was 10 days (range, 5-24 days) and time to removal of the urinary catheter was 3 days (range, 1-21 days). The median total number of lymph nodes harvested was 24 (range, 8-43), and total number of lateral pelvic lymph nodes was 7 (range, 2-23). Six patients (28.6%) developed postoperative complications; three with an anastomotic leakages, two with ileus and one patient with chyle leakage. Two patients (9.5%) developed urinary incontinence. There was no mortality within 30 days. During a median follow-up of 14 months, two patients developed lung metastasis and there was no local recurrence. CONCLUSION: Robotic and laparoscopic LPND is technically feasible and safe. Minimally invasive techniques for LPND in selected patients can be an acceptable alternative to an open LPND.

OBJECTIVETo investigate the associated factors for postoperative ileus following radical resection for colorectal cancer.

METHODSClinical data of 1366 colorectal cancer patients undergoing radical resection by the same surgical team in our hospital from January 2000 to September 2011 were analyzed retrospectively. Univariate analysis and multivariate logistic regression analysis were used to identify the associated factors of postoperative ileus.

RESULTSA total of 70 patients(5.1%) developed postoperative ileus. Univariate and multivariate analyses showed that N2(OR=1.893, 95%CI:1.083-3.306), history of colorectal cancer resection(OR=4.899, 95%CI:1.490-16.110), preoperative obstruction (OR=2.616, 95%CI:1.297-5.280), right hemicolectomy(OR=2.024, 95%CI:1.052-3.894) and left hemicolectomy(OR=3.030, 95%CI:1.401-6.550) were risk factors for postoperative ileus following radical resection for colorectal cancer, while laparoscopic operation(OR=0.520, 95%CI:0.319-0.849) was protective.

CONCLUSIONSPostoperative ileus following radical resection for colorectal cancer is associated with surgical procedures. Laparoscopic colorectal resection can reduce the incidence of postoperative ileus.

PURPOSE: Postoperative ileus (POI) is an impairment of coordinated gastrointestinal (GI) motility that develops as a consequence of abdominal surgery and is a major factor contributing to patient morbidity and prolonged hospitalization. The aim of this study was to investigate the effects of different 5-hydroxytryptamine 4 (5-HT4) receptor agonists, which stimulate excitatory pathways, on a POI model. MATERIALS AND METHODS: The experimental model of POI in guinea pigs was created by laparotomy, gentle manipulation of the cecum for 60 seconds, and closure by suture, all under anesthesia. Different degrees of restoration of GI transit were measured by the migration of charcoal. Colonic transit was indirectly assessed via measurement of fecal pellet output every hour for 5 hours after administration of various doses of mosapride, tegaserod, prucalopride, and 5-HT. RESULTS: Charcoal transit assay showed that various 5-HT4 receptor agonists can accelerate delayed upper GI transit in a dose-dependent manner. However, fecal pellet output assay suggested that only prucalopride had a significant effect in accelerating colonic motility in POI. CONCLUSION: Although mosapride, tegaserod, and prucalopride produce beneficial effects to hasten upper GI transit in the POI model, prucalopride administered orally restores lower GI transit as well as upper GI transit after operation in a conscious guinea pig. This drug may serve as a useful candidate for examination in a clinical trial for POI.
