OBJECTIVE: To systematically evaluate the safety and efficacy of laparoscopic surgery versus conservative treatment for appendiceal abscess. METHODS: The databases of CNKI, Wangfang, VIP, PubMed, EMBASE and Cochrane Library were searched to retrieve randomized controlled trials (RCT) or clinical controlled trials (CCT) comparing laparoscopic surgery with conservative treatment for appendiceal abscess published before June 2018. The search terms were Chinese or English. Chinese search terms included appendix, abscess, and laparoscopy; English search terms included appendix, abscess, and laparoscope. References of the resulted papers, related reviews or meta-analysis references were also induded. Literature inclusion criteria: (1)RCT or CCT, whether or not to assign concealment or blinding; (2) appendiceal abscess was diagnosed at admission; (3) laparoscopic group: laparoscopic appendectomy or laparoscopy surgical methods, such as irrigation and drainage, for appendiceal abscess; conservative treatment group: conservative methods, such as antibiotics or percutaneous abscess drainage were used to treat appendiceal abscess. EXCLUSION CRITERIA: (1) review, case report, single cohort study and other non-controlled studies literature; (2) single study sample size ≤ 20; (3) subjects with simple appendicitis or perforation of appendix to form diffuse peritonitis; (4) no valid data available for extraction; (5) repeated publication of the literature. Data were extracted from the included studies, and the Cochrane Collaboration RevMan 5.1.0 version software was used for this meta-analysis. RESULTS: Three RCTs and four CCTs with a total of 591 patients were included in this study. There were 312 patients in the laparoscopic group and 279 patients in the conservative group. Compared with the conservative group, the laparoscopic group had higher uneventful recovery rate (OR=11.91, 95%CI: 4.59 to 30.88, P<0.05), shorter hospital stay (WMD=-2.98, 95%CI: -5.96 to -0.01, P=0.05), lower incidence of recurrent or residual abscess (OR=0.07, 95%CI:0.03 to 0.20, P<0.05), and shorter time to recover to normal condition for body temperature and white blood cell respectively (SMD=-2.12, 95%CI:-2.49 to -1.75, P<0.05; SMD=-2.07, 95%CI: -3.84 to -0.29, P<0.05). However, no significant difference was found in hospital charge(P>0.05). CONCLUSIONS Laparoscopic surgery for appendiceal abscess is safe and feasible. It can improve the recovery with shorter postoperative hospital stay and less recurrent or residual abscess.

Pediatric onset Crohn's disease (CD) tends to have complicated behavior (stricture or penetration) than elderly onset CD at diagnosis. Considering the longer duration of the disease in pediatric patients, the accumulative chance of surgical treatment is higher than in adult onset CD patients. Possible operative indications include perianal CD, intestinal stricture or obstruction, abdominal abscess or fistula, intestinal hemorrhage, neoplastic changes and medically untreatable inflammation. Growth retardation is an operative indication only for pediatric patients. Surgery can affect a patient's clinical course, especially for pediatric CD patient who are growing physically and mentally, so the decision should be made by careful consideration of several factors. The complex and diverse clinical conditions hinder development of a systemized treatment algorithm. Therefore, timing of surgery in pediatric CD patients should be determined with individualized approach by an experienced and well organized multidisciplinary inflammatory bowel disease team. Best long-term outcomes will require proactive post-operative monitoring and therapeutic modifications according to the conditions.

OBJECTIVETo evaluate the diagnostic value of preoperative CT enterography (CTE) on obstruction, fistula and abscess formation compared to intraoperative findings in patients undergoing surgery for Crohn's disease(CD), aiming to provide reference to clinical practice.

METHODSPreoperative CTE data of 176 CD patients confirmed by clinic, endoscopy, imaging, operation and pathology at the Department of General Surgery in Nanjing Jinling Hospital from January 2013 to December 2015 were enrolled in retrospective cohort study. All the patients underwent enhanced full abdominal CT scan using SIMENS SOMATOM Definition Flash 64 row dual-source CT machine. CTE scans were performed from the dome of diaphragm to the symphysis pubis. The CT images in arterial and venous phase were reconstructed with 1.0 mm thin layer, and then processed in MMWP 4.0 workstation including multi-planar recombination, surface recombination and maximum density projection. The sensitivity, specificity, positive and negative predictive value, false negative rate and accuracy of preoperative CTE on obstruction, fistula and abscess were compared with intraoperative findings.

RESULTSAmong 176 patients, 122 were males and 54 were females with median age of 29 (18 to 65) years, median disease duration of 48 (1 to 240) months, median time interval from CT scan to operation of 16(1 to 30) days, and median body mass index of 17.8 (10.8 to 34.7) kg/m. Twenty-six cases (14.8%) had nutritional risk (NRS2002≥3); 23 cases (13.1%) had lesions limited to ileum; 19 cases (10.8%) had lesions limited to colon; 126 cases (71.6%) had simultaneous lesions of ileum and colon, and 8 cases (4.5%) had lesion in upper gastrointestinal tract. A total of 199 lesions of small intestine were identified by preoperative CTE, including 131 of obstruction (65.8%), 42 of fistula (21.1%), and 26 of abscess (13.1%), while 235 lesions were confirmed by operation, including 133 of obstruction (56.6%), 74 of fistula (31.5%), 28 of abscess (11.9%). The modification of planned surgical procedure due to unexpected intraoperative findings were found in 29(16.5%) patients. The sensitivity, specificity, positive predictive value and negative predictive value of preoperative CTE were 86.4%, 78.8%, 86.9% and 76.0% for obstruction; 83.8%, 79.1%, 67.5% and 90.4% for fistula; and 96.2%, 98.0%, 90.1% and 99.3 for abscess, respectively.

CONCLUSIONPreoperative CTE can effectively evaluate the lesions of intestinal obstruction, fistula and abscess in CD patients, with the highest accuracy of abscess, and has quite good consistency with intraoperative findings, which may be used as the first choice of imaging diagnosis of CD.

OBJECTIVETo investigate the predictive value of procalcitonin(PCT) in postoperative intra-abdominal infections (IAI) after definitive operation of intestinal fistulae(IF).

METHODSWith the exclusion of emergence operation, preoperative clinical infection, preoperative renal or hepatic dysfunction, and age less than 18 years, a total of 356 consecutive patients who underwent elective digestive tract reconstruction of intestinal fistulae from February 2012 to December 2015 at Intestinal Fistula Center of Jinling Hospital were prospectively enrolled in the study. All the patients were divided into IAI group (26 cases, 21 of anastomosis leakage and 5 of peritoneal abscess) and non-IAI group (330 cases) based on the existence of postoperative IAI. The non-IAI group was then divided into two subgroups of other infection (93 cases) and non-infection(237 cases) according to the presence of other infections. Plasma PCT level, serum CRP concentration and WBC count were assessed preoperatively and on postoperative days (PODs) 1, 3, 5, 7 by immunofluorescence, turbidimetry and automatic blood analyzer, respectively. The predictive value of each marker for IAI was calculated by receiver operating characteristic (ROC) curve.

RESULTSThere was no significant difference in general clinical data between IAI and non-IAI group (all P>0.05). The proportions of multi-IF (53.8%, 14/26) and colectomy (61.5%, 16/26) in IAI group were higher than those of non-IAI group [20.0% (66/330), χ=15.847, P=0.000 and 31.2%(103/330), χ=9.961, P=0.002]. Differences of preoperative PCT, CRP and WBC levels among IAI, other infection and non-infection groups were not significant. These three markers all increased obviously and immediately after surgery. PCT and WBC values reached the peak point on POD 1, whereas CRP on POD 3. In IAI group, mean PCT values were (5.4±4.2) μg/L, (2.9±1.9) μg/L and (1.6±1.8) μg/L on POD 1, POD 3 and POD 5, respectively, which were higher than those of other infection group [(4.2±8.7) μg/L, (1.9±3.8) μg/L and (0.6±0.8) μg/L] and non-infection group [(2.7±5.8) μg/L, (1.1±1.7) μg/L and (0.5±0.7) μg/L, all P<0.05]. Mean CRP values in IAI group were 99.4 mg/L and 183.9 mg/L respectively on POD 1 and POD 3,and mean WBC values of IAI group on POD 1, POD 3 and POD 5 were 16.0×10/L, 10.8×10/L and 8.7×10/L, respectively, which were all significantly higher than those in the other 2 groups (all P<0.05). No significant differences were obtained between other infection group and non-infection group in all these three markers (all P>0.05). ROC curve demonstrated that PCT had the biggest area under the curve (AUC) of 0.86 and 0.84 on POD 3 and POD 5, with the cut-off value of 0.98 μg/L and 0.83 μg/L, 92.0% sensitivity and 74.0% specificity, 91.0% sensitivity and 73.0% specificity, respectively. The highest AUC was 0.72 on POD 3 for CRP and 0.71 on POD 3 for WBC, with 80.0% sensitivity and 54.0% specificity, 56.0% sensitivity and 73.0% specificity, respectively.

CONCLUSIONThe value of procalcitonin above 0.98 μg/L on POD 3 and 0.83 μg/L on POD 5 can predict the occurrence of IAI after definitive operations of intestinal fistulae.

OBJECTIVETo compare the safety of anastomosis and ostomy following 2-stage definitive colonic resection when severe colonic injuries treated in the setting of damage control surgery(DCS).

METHODSClinical data of 67 patients with severely traumatic colonic injuries undergoing DCS at the Third Affiliated Hospital of Sun Yat-sen University between 2005 and 2013 were analyzed retrospectively. Patients were divided into the anastomosis group undergoing colonic resection and anastomosis (n=40), and the ostomy group undergoing anastomosis with a protecting proximal ostomy (n=27). Postoperative complications were compared between these two groups. The risk factors of colonic anastomosis leakage were analyzed.

RESULTSDemographics, injury severity, physiological imbalance on admission, transfusion during the first operative procedure were similar in the two groups (all P>0.05). Rates of anastomotic leakage, intra-abdominal abscess, enterocutaneous fistula, and would infection after definitive resection were not statistically different between the two groups (all P>0.05). Colonic anasomotic leakage rates were 15.0% (6/40) in anastomosis group and 11.1% (3/27) in ostomy group without significant difference (P>0.05). Left-sided colon injuries occurred in 7 out of 9 patients with anatomotic leakage, whose proportion was significantly higher than that in those without anastomotic leakage (7/9 vs. 24/58, 77.8% vs. 41.4%, P<0.05). A prolonged peritoneal closure was also observed in patients with anastomotic leakage (median, 10 days vs. 2 days, P<0.05).

CONCLUSIONSA strategy of diverting ostomy is not the first choice for patients suffering from severe colonic injuries in the setting of DCS. Peritoneal closure at early stage may decrease the risk of colonic anastomotic leakage.

Endoscopic drainage for pancreatic and peripancreatic fluid collections (PFCs) has been increasingly used as a minimally invasive alternative to surgical or percutaneous drainage. Recently, endoscopic ultrasound-guided transluminal drainage (EUS-TD) has become the standard of care and a safe procedure for nonsurgical PFC treatment. EUS-TD ensures a safe puncture, avoiding intervening blood vessels. Single or multiple plastic stents (combined with a nasocystic catheter) were used for the treatment of PFCs for EUS-TD. More recently, the use of covered self-expandable metallic stents (CSEMSs) has provided a safer and more efficient approach route for internal drainage. We focused our review on the best approach and stent to use in endoscopic drainage for PFCs. We reviewed studies of EUS-TD for PFCs based on the original Atlanta Classification, including case reports, case series, and previous review articles. Data on clinical outcomes and adverse events were collected retrospectively. A total of 93 patients underwent EUS-TD of pancreatic pseudocysts using CSEMSs. The treatment success and adverse event rates were 94.6% and 21.1%, respectively. The majority of complications were of mild severity and resolved with conservative therapy. A total of 56 patients underwent EUS-TD using CSEMSs for pancreatic abscesses or infected walled-off necroses. The treatment success and adverse event rates were 87.8% and 9.5%, respectively. EUS-TD can be performed safely and efficiently for PFC treatment. Larger diameter CSEMSs without additional fistula tract dilation for the passage of a standard scope are needed to access and drain for PFCs with solid debris.

OBJECTIVETo investigate the risk factors for anastomotic infectious complications after bowel resection in patients with Crohn disease.

METHODSClinical data of 124 patients with Crohn disease undergoing bowel resection between January 1990 and October 2012 were analyzed retrospectively. The risk factors were identified by χ(2) test and Logistic regression.

RESULTSFourteen patients (12.3%, 14/114) developed anastomotic infectious complications in the postoperative period, including anastomotic leak (n=7), intra-abdominal abscess (n=6), and enterocutaneous fistula (n=1). Crohn disease activity index (CDAI)>150 (OR=2.185, 95%CI:1.098-6.256, P=0.040), steroid usage (OR=2.674, 95%CI:1.118-8.786, P=0.027), and the presence of preoperative abscess/fistula (OR=3.447, 95%CI:1.254-10.462, P=0.014) were identified as independent risk factors of anastomotic infectious complications. In the absence of these 3 risk factors, the rate of anastomotic infectious complication was 5.7% (3/53), which increased to 11.4% (4/35) when one risk factor was present, 21.1% (4/19) when two risk factors were present, and 42.9% (3/7) when all the 3 risk factors were present.

CONCLUSIONSCDAI>150, steroid usage and preoperative abscess/fistula are associated with higher rates of anastomotic infectious complications following bowel resection for Crohn disease. A prudent management should be carried out if risk factors can not be eliminated preoperatively.

PURPOSE: Band erosion is a well-known complication of laparoscopic adjustable gastric band placement. We gained experience with laparoscopic removal of an eroded gastric band. METHODS: We retrospectively reviewed the operative log of our obesity surgery unit to identify all operations performed for band erosion from March 2009 to May 2011. RESULTS: During the study period, a total of six of 96 patients (6.3%), five females and one male, were diagnosed with band erosion and underwent surgical removal of the band system. The median time interval from the initial gastric band placement to the diagnosis of band erosion was 8.5 months (range, 7 to 22 months), with most band erosion occurring within the first year (5/6, 83%). The median body mass index at band removal was 28.4 kg/m2. Upper abdominal pain was the most common symptom (5/6, 83%), and other signs and symptoms were port site infection (3/6, 50%) and loss of restriction and weight regain (1/6, 17%). All eroded bands were removed using laparoscopy. Further complications after laparoscopic removal of the band system were observed in three cases. One patient showed multiple intra-abdominal abscesses requiring insertion of a pigtail catheter for drainage. The other two patients experienced sepsis with localized peritonitis, eventually requiring laparoscopic washout and drainage. CONCLUSION: Gastric band erosion requires the removal of the gastric band. Laparoscopic removal is technically achievable in the majority of patients with eroded gastric band. The method can be challenging, has potential postoperative complications (fistula, abscess), and should be attempted only by experienced surgeons.

Use of laparoscopic appendectomy (LA) for perforated appendicitis (PA) in children remains controversial because of the development of postoperative intra-abdominal abscess formation. We developed the irrigation method for the prevention of abscess formation after LA performed for PA in children with severe panperitonitis. We called it 'the shaking irrigation'. The object of this study was to analyze the efficacy of this irrigation method. All cases of PA with severe panperitonitis in children that underwent LA with massive shaking irrigation and drainage between June 2003 and December 2007 were studied retrospectively. We included only PA with panperitonitis and large amounts of purulent ascites throughout the abdomen as well as an inflamed small bowel with ileus. Thirty-four children were involved in this study. The mean patient age was eight years. The mean amount of irrigation fluid was 8.2L (range: 4-15L). The mean operative time was 89.5 min. The mean length of the hospital stay was 5.1 days. There were no postoperative intra-abdominal abscesses. There was no conversion to open surgery. In conclusion, Use of LA in PA with severe panperitonitis in children is safe and effective. Massive shaking irrigation and abdominal drainage appears to prevent intra-abdominal abscesses after LA for PA with panperitonitis.

OBJECTIVETo study the effects of placement of double cannula using trocar puncture for intra-abdominal abscess drainage.

METHODSA retrospective study was performed to investigate the clinical data of 32 patients undergoing intra-abdominal abscess drainage with double cannula placed using trocar puncture between June 2010 and December 2010.

TECHNIQUESthe location and size of the abscess was evaluated by ultrasound and CT. Placement of double cannula using trocar puncture was performed under CT or ultrasound guidance.

RESULTSTrocar puncture was successful in all the patients. One patient died of liver metastasis and multiple organ failure after surgery for pancreatic cancer. One patient required laparotomy and drainage because non-localization of sepsis from intestinal fistula. The remaining 30 patients experienced alleviation of septic symptoms after drainage and eventually cured. The mean healing time was(7±3) days. Two patients developed subcutaneous bleeding and were management by local compression.

CONCLUSIONSPlacement of double cannula using trocar puncture for intra- abdominal abscess drainage results in satisfactory outcomes. This technique is especially suitable for abscesses with viscous drainage, those with the presence of phlegmon or necrotic debris, and those with multiple large cavities.
