Objective:To investigate the diagnosis and treatment of emergency inguinal hernia.Methods:The retrospective cross-sectional study was conducted. The clinical data of 236 patients with emergency inguinal hernia who were admitted to the First Affiliated Hospital of Soochow University from January 2015 to May 2020 were collected. There were 194 males and 42 females, aged (69±30)years. Hospitalized patients received routine blood biochemistry test and imaging examinations for evaluation of characteristics of hernia contents and intestinal obstruction. Manual reduction and surgical treatment were selected according to the conditions of patients. Observation indicators: (1) treatment; (2) follow-up. Follow-up using outpatient examination and telephone interview was performed to detect hernia recurrence and late-onset mesh infection up to August 2020. Measurement data were described as M (range) or M ( P25, P75), and comparison between groups was analyzed using the Wilcoxon rank sum test. Count data were represented as absolute numbers, and comparison between groups was done using the chi-square test. Results:(1) Treatment: of the 236 patients, 106 cases had successful manual reduction, 124 cases underwent emergency operation, 6 cases refused surgery. ① For 106 cases with successful manual reduction (including 4 cases guided by B-ultrasonography), the manual reduction time was 5 minutes (2 minutes,7 minutes). Ninety-three of 106 patients underwent selective operation after manual reduction, including 89 cases with indirect hernia, 2 cases with direct hernia and 2 cases with compound hernia. The time to selective operation was 3 days(2 days,5 days) after manual reduction. Patients underwent mesh repair, of which the operation time, volume of intraoperative blood loss, time to postoperative first flatus, duration of postoperative hospital stay were 44 minutes (29 minutes, 66 minutes),10 mL(5 mL,20 mL), 1 day(1 day,2 days), 1 day(1 day,2 days), respectively. Eleven patients didn't undergo selective operation. Two patients with abdominal pain and fever after manual reduction were diagnosed with perforation of intestine by emergency surgical exploration, and then underwent partial intestinal resection combined with high ligation of hernial sac. ② There were 93 of 124 patients undergoing emergency operation with indirect hernia, 18 cases with femoral hernia, 6 cases with obturator hernia, 6 cases with compound hernia and 1 case with direct hernia. There were 54 of 124 patients undergoing open operation, including 21 cases with Bassini surgery, 18 cases with Lichtenstein surgery, 9 cases with Mc Vay surgery, 6 cases with high ligation of hernia sac. There were 70 patients undergoing laparoscopic operation, including 57 cases with laparoscopic transperitoneal preperitoneal hernia repair (TAPP), 10 cases with laparoscopic explora-tion + tissue repair and 3 cases with laparoscopic exploration + closure of inner inguinal ring. The operation time, volume of intraoperative blood loss, time to postoperative first flatus, cases with short-term postoperative complications were 60 minutes (50 minutes,76 minutes), 20 mL(14 mL,30 mL), 2 days(1 day,2 days), 15 cases for patients undergoing open surgery, respectively. The above indicators were 56 minutes (47 minutes,77 minutes), 20 mL(10 mL,25 mL), 2 days(1 day,2 days), 21 cases for patients under-going laparoscopic surgery. There was no significant difference in the above indicators between the two groups ( Z=?0.88, ?1.37, ?1.56, χ2=0.07, P>0.05). Cases with intraoperative placement of mesh and duration of hospital stay were 18 cases and 5 days(3 days,8 days) for patients undergoing open surgery, versus 57 cases and 3 days(2 days,5 days) for patients undergoing laparoscopic surgery, showing significant differences between the two groups ( χ2=29.50, Z=?4.32, P<0.05). (2) Follow-up: of 236 patients, 192 were followed up for 2?60 months, with a median follow-up time of 19 months. Seven patients had recurrence of hernia after emergency operation, including 3 with high ligation of the hernia sac, 2 with Bassini surgery, 1 with Lichtenstein surgery, and 1 with laparoscopic exploration + closure of inner inguinal ring. One patient with late-onset mesh infection after Lichtenstein surgery was improved after mesh removal. No long-term complications such as hernia recurrence or late-onset mesh infection occurred to the 184 patients. Conclusions:Emergency inguinal hernia had different state of illness, manual reduction is suitable for partial patients with incarceration. Surgery is the first choice, and the surgical procedure needs to be individually selected.

Hospital is a crowded place, and the population health management is very important. In the context of the normalized control of COVID-19, it is crucial to establish a set of insensitive, intelligent and effective crowd diversion management strategies. By deeply integrating information technologies such as big data processing, movement tracking and face recognition, Hangzhou Ninth People′s Hospital built a set of crowd health management and population diversion work mechanism, which included temperature monitoring, health code inspection and epidemiological history investigation. The mechanism could effectively promote the efficiency and accuracy of hospital population health screening under the situation of normalized epidemic prevention and control.

Objective:To investigate the clinical effect of locking plate combined with large autologous iliac bone implantation in treatment of complex proximal humeral fractures with comminuted proximal humerus and bone defect.Methods:A retrospective case-control study was conducted to analyze the clinical data of 52 elderly patients with proximal humeral fracture accompanied by comminuted and bone defect admitted to General Hospital of Jizhong Energy Xingtai Mining Group from January 2014 to March 2017. including 24 males and 28 females, aged 65-79 years, with an average age of 69 years. There were 36 patients with Neer's three-part fracture and 16 four-part fracture. Twenty-two patients were treated using locking plate combined with large autologous iliac bone graft (plate+ bone graft group), and 30 patients were treated using locking plate alone (plate group). The deltoid-pectoralis major approach was used in both groups. Operation time, bleeding volume and bone healing time were recorded. neck-trunk angle and shoulder joint range of motion were measured at the last follow-up . MOS 36-item short-form health survey (SF-36) score and visual analog scale (VAS) score were used to evaluate shoulder joint function and pain at last follow-up. Complications were observed as well.Results:All patients were followed up for 6-24 months, with an average of 17. 8 months. Operation time was (120.3±12.5)minutes in plate+ bone graft group, and (115.6±5.8)minutes in plate group ( P<0.01). Intraoperative bleeding volume was (400.8±15.8)ml in plate+ bone graft group and (300.2±16.2)ml in plate group ( P<0.05). Bone healing time was (2.2±0.5)months in plate+ bone graft group and (2.5±0.5)months in plate group ( P>0.05). At last follow-up, the neck-trunk angle was (132.3±10.6)°in plate+ bone graft group and (121.1±4.5)° in plate group ( P<0.01); the uplift and external rotation of shoulder joint was (149.2±3.7)° and (35.2±2.9)° in plate+ bone group, better than that in plate group [(135.1±2.1)°, (27.8±4.5)°] ( P<0.05). Meanwhile, the abduction and extension of shoulder joint was (118.4±13.9)°and (36.1±1.8)°in plate+ bone graft group, not significantly different from that in plate group [(110.8±21.9)°, (32.8±1.3)°] ( P>0.05). SF-36 score and VAS score in plate+ bone graft group was (87.3±4.7)points and (1.3±0.6)points, with significant difference from that in plate group [(70.9±7.2)points, (2.1±0.7)points]( P<0.05 or 0.01). One year after operation, 3 patients with humeral head varus and 1 patient with humeral head necrosis were observed in plate group, with the complication incidence of 13% (4/30); while 1 patient with absorption of humeral greater tuberosity in plate+ bone graft group, with complication incidence of (5%, 1/22) ( P<0.05). Conclusion:For complex proximal humeral fractures with comminuted proximal humerus and bone defect, locking plate combined with large autologous iliac bone implantation can maintain intraoperative reduction, avoid loss of neck-shaft angle, improve shoulder joint range of motion, promote function recovery, attenuate pain and reduce incidence of complications.

Objective:The operative approach and steps of laparoscopic right hemicolon cancer radical resection have been standardlized and professional consensus has been reached. However, some detailed issues such as the handling of Henle's trunk and whether to preserve the right gastroepiploic vein (RGEV) still remain controversial. This study investigates the safety, feasibility, short- and long-term outcomes of preserving RGEV during laparoscopic right hemicolectomy.Methods:A retrospective cohort study was carried out. Clinical data of 92 patients undergoing laparoscopic right hemicolectomy in Taizhou People's Hospital from March 2016 to May 2018 were retrospectively analyzed. All the patients were treated with complete mesocolon resection (CME) and had complete postoperative pathological data and follow-up data. Based on the tumor location, 49 patients preserved RGEV (preservation group) and 43 did not (non-preservation group). Pathological data, postoperative complications, short- and long-term outcomes were compared between the two groups.Results:There were no significant differences in baseline data between the two groups (all P>0.05). No significant differences were found in operation time, intraoperative blood loss, unplanned reoperation, anastomotic leak, number of harvested lymph nodes, number of metastatic lymph node, and time to food intake after surgery between two groups (all P>0.05). Compared with non-preservation group, the preservation group had faster recovery of anal gas passage after operation [(3.1±1.0) days vs. (4.0±1.7) days, t=-2.787, P=0.007], shorter length of hospitalization [(11.5±1.5) days vs. (15.0±7.9) days, t=-2.823, P=0.007], and reduced the hospitalization expenses [(46 000±5000) yuan to (57 000±33 000) yuan, t=-2.076, P=0.044]. No postoperative gastroparesis (PGS) occurred in the preservation group, while 6 cases in the non-preservation group developed gastroparesis during perioperative period ( P<0.05). The median time of follow-up time was 31.8 (5.2-43.7) months. The overall survival time of the preservation group and non-preservation group was (35.4±1.8) months and (37.6±1.7) months, respectively without significant difference ( P=0.336); the disease-free survival was (32.0±2.2) months and (35.5±2.0) months, respectively without significant difference as well ( P=0.201). Conclusions:Dissection of the Henle's truck and preservation of RGEV is safe and feasible during laparoscopic right hemicolectomy, which can significantly reduce the incidence of postoperative gastroparesis, shorten the recovery time of postoperative intestinal function and hospitalization, and decrease the cost of hospitalization. The efficacy of RGEV preservation is similar to non-preservation of RGEV.

BACKGROUND: Particulated juvenile cartilage allograft is simple and easy to obtain, and relevant clinical studies are underway in the USA. However, how the transplanted juvenile cartilage fragments exert biological effects through biochemical mechanisms and genetic signal transduction is still unclear. There is as yet no report on this technology in China. OBJECTIVE: To explore the feasibility of articular cartilage defects repaired with particulated juvenile cartilage allograft. METHODS: The cartilage fragments were obtained from juvenile Pitman-Moore strains (provided by the Laboratory Animal Center of the Army Medical University in China) and cultured in vitro. Brdu immunofluorescence assay was performed at 1, 3, and 7 days of culture. The particulated juvenile cartilage allograft/fibrin gel composites were subcutaneously transplanted into the SCID rats (provided by the Laboratory Animal Center of the Army Medical University). The specimens were taken for hematoxylin-eosin staining, safranin O staining and immunohistochemistry after 1 month. Cartilage defects of 8 mm in diameter were made in the knee joint of 10 adult Pitman-Moore strains (Laboratory Animal Center of the Army Medical University), and were randomized into two groups, which were then transplanted with the particulated juvenile cartilage allograft/fibrin gel composites (experimental group) or nothing (control group). The specimens were taken for hematoxylin-eosin staining, safranin O fast green staining, toluidine blue and immunohistochemistry at 3 months after transplantation. RESULTS AND CONCLUSION: Little Brdu incorporation was detected in juvenile cartilage fragments at 1 day of culture, some Brdu incorporation was defected at 3 days of culture. At 7 days of culture, a progressive increase in the Brdu signal was detected in chondrocytes within the cultured cartilage fragments, which seemed to localize along the tissue edge. At 1 month after subcutaneous transplantation, the particulated juvenile cartilage allograft still survived and were surrounded by few proliferative chondrocytes. There was no obvious tissue repair in the control group at 3 months after transplantation. In the experimental group, there was obvious tissue repair, the color of the newly formed tissues was similar to the normal cartilage tissue, which integrated well with the surrounding normal cartilage tissue, and the cells distributed evenly. These results imply that particulated juvenile cartilage allograft can achieve good results in repairing articular cartilage defects.

OBJECTIVE: To explore the feasibility, safety and the economical efficiency of double-pouch anastomosis in laparoscopic radical rectal cancer assisted by small incisions. METHODS: Clinical data of 224 patients undergoing gastrointestinal surgery at Taizhou People's Hospital of Jiangsu Province from January 2011 to December 2017 were retrospectively analyzed. Indusion criteria: patients were diagnosed as primary rectal adenocarcinoma by preoperative enteroscopy pathology, the distance of the tumor to anal margin was from 4 to 15 cm, and patients were treated with laparoscopic total mesorectal excision(TME) through small incision. Patients were divided into two groups according to different anastomosis method, double-pouch group(108 cases) and single-pouch group (116 cases). The surgical indexes, tumor safety indexes, short-term efficacy and economic indexes were compared between the two groups. RESULTS: There was no significant difference between two groups in baseline data, operative time, blood loss, number of lymph nodes dissection, average length of proximal and distal bowel, or incidence of urination and sexual dysfunction (all P>0.05). Compared with the single-pouch group, the double-pouch group presented lower anastomotic secondary bleeding rate [0.9%(1/108) vs. 6.0% (7/116), χ²=4.238, P=0.040], lower incidence of anastomotic leakage[1.9%(2/108) vs. 7.8%(9/116), χ²=4.179, P=0.041], lower incidence of anastomotic stricture [1.9% (2/108) vs. 8.6% (10/116), χ²=5.054, P=0.025], shorter hospital stay [(13.4±3.9) days vs. (15.9±9.8) days, t=2.524, P=0.013] and less average hospitalization costs [(34 000±7 000) yuan vs. (46 000±23 000) yuan, t=5.047,P<0.001]. There was no significant difference in local recurrence, distant metastasis or overall survival between the two groups during mean follow-up of 33 months (all P>0.05). CONCLUSION Laparoscopic TME assisted by small incision with double-pouch anastomosis is a safe, feasible and economical method.

OBJECTIVETo evaluate the feasibility, safety, radicality and short-term outcome of preserving left colic artery (LCA) during laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer.

METHODSFrom January 2013 to December 2016,136 patients with mid-lower rectal cancer received laparoscopic TME in the Gastrointestinal Surgery Department of Taizhou People's Hospital of Jiangsu Province. Patients with rectal tumor within 10 cm to the anal verge were enrolled into the study. All the enrolled patients had complete data of pathology and follow-up. Those receiving neoadjuvant chemoradiotherapy, with severe base diseases, multifocal tumor, tumor invasion of surrounding tissues, fixation of tumor, recurrent tumor, complications such as acute ileus, bleeding, perforation were excluded. In this study, 72 patients did not undergo preservation of LCA (high ligation group) and 64 patients underwent preservation of LCA (low ligation group). Operative parameters, clinicopathological data and short-term outcome were collected and compared between two groups.

RESULTSThe baseline data including gender, age, body mass index, tumor stage, and distance of tumor from anal verge of two groups were comparable (P>0.05). The differences between two groups about the mean time of operation and the operative blood loss were not significant [(164.0±12.6) min vs. (167.3±9.4) min, (30.0±3.6) ml vs. (30.1±3.0) ml, all P>0.05]. There was no operative death in both groups. Differences in the lymph node dissection (13.7±2.6 vs. 13.3±2.1) and the specimen length of proximal resection margin [(16.4±1.9) cm vs. (16.7±2.1) cm] or distal resection margins [(3.9±0.6) cm vs. (4.1±0.9) cm] between high and low ligation groups were not significant (all P>0.05). Compared with high ligation group, the low ligation group had higher rate of sphincter preservation [92.2% (59/64) vs. 79.2% (57/72), χ=4.580, P=0.032], lower rate of anastomotic leakage [1.6% (1/64) vs. 9.7% (7/72), χ=4.075, P=0.044], anastomotic stenosis [3.1% (2/64) vs. 12.5%(9/72), χ=4.006, P=0.045], and voiding and sexual dysfunction [6.3%(4/64) vs. 18.1%(13/72), χ=4.317, P=0.038]. Mean time of follow-up was 19 months. In high ligation group, the local recurrent rate was 5.56%, distant metastasis rate was 13.89%, overall survival rate was 90.28%, disease-free survival rate was 80.56%, while in low ligation group, the local recurrence rate was 4.69%, distant metastasis rate was 12.50%, overall survival rate was 90.63%, disease-free survival rate was 82.81%, whose differences between two groups were not significant (all P>0.05).

CONCLUSIONPreservation of LCA during laparoscopic TME for the treatment of rectal cancer is safe and feasible, which can reduce the incidence of anastomotic leakage and stenosis, and voiding and sexual dysfunction.

OBJECTIVETo evaluate the clinical significance of No.12 lymph node dissection for advanced gastric cancer with D2 lymphadenectomy.

METHODSClinicopathologic data and No.12 lymph node dissection of 256 advanced gastric cancer patients undergoing radical operation in our department between January 2005 and December 2010 were retrospectively summarized and the influence factors of metastasis in No.12 lymph nodes were analyzed.

RESULTSOf 256 patients, 179 were male and 77 were female with the average age of 59.2 years. Tumor located in the upper of stomach in 24 cases, middle of stomach in 41 cases, lower of stomach in 174 cases, multi-focus or diffuse distribution of stomach in 17 cases. Tumor diameter was <3 cm in 39 cases, 3 to 5 cm in 100 cases, >5 cm in 117 cases. Serum carcinoembryonic antigen (CEA) level increased in 61 cases, serum carbohydrate antigens (CA)72-4 increased in 56 cases and CA19-9 increased in 61 cases. The number of No.12 lymph nodes resected from all the patients was 1 152, and the average number was 4.5±1.9. The metastasis rate of No.12 lymph nodes was 9.4%(24/256) after hematoxylin eosin staining (positive group). All the patients received effective follow-up to December 2015, and the average follow-up time was 101.2 months. The median survival time of positive No.12 group (24 cases) was 29.8 months and of negative No.12 group (232 cases) was 78.2 months, whose difference was statistically significant (χ=21.715, P=0.000). Univariate analysis found that No.12 lymph node metastasis was not associated with age, gender, tumor differentiation (all P>0.05), but was associated with tumor location, tumor diameter, invasive depth (all P<0.05), and was closely associated with Borrmann type, outside metastatic lymph nodes of No.12 and high levels of serum CEA, CA72-4 and CA19-9 (all P=0.000). Multivariate regression analysis found that tumor location (RR=2.452, 95%CI:1.537 to 3.267, P=0.000), Borrmann type (RR=1.864, 95%CI:1.121 to 3.099, P=0.016) and number of outside metastatic lymph nodes of No.12 (RR=2.979, 95%CI: 2.463 to 3.603, P=0.000) were the independent risk factors of the No.12 metastasis (P<0.05).

CONCLUSIONSMetastasis in No.12 lymph nodes indicates poorer prognosis. The No.12 lymph nodes of advanced gastric cancer patients with curative resection, especially those with the tumor located in the lower part, Borrmann type IIII(, outside metastatic lymph nodes of No.12, should be regularly cleaned.
