ABSTRACT
Objective:To explore the curative effect of surgical treatment for Crohn′s disease (CD), to investigate the timing of surgical intervention and the choice of surgical methods.Methods:From January 1, 2016 to August 31, 2020, at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, the clinical data of 123 patients with CD and receiving surgical treatment were retrospectively analyzed, which included the type of lesion, the location of lesion, clinical manifestation, surgical method, preoperative inflammatory and nutritional indicators, postoperative recovery of digestive tract function, and the development and treatment of postoperative complications. CD was diagnosed according to Consensus opinion on diagnosis and treatment of inflammatory bowel disease ( Beijing 2018). Patient was classitied according to the Montreal Classification. Postoperative complications were graded according to the Clavien-Dindo Criteria. Mann-Whitney U test was used for statistical analysis. Results:Among 123 patients, according to the Montreal classification, two cases (1.6%) were diagnosed at ≤16 years old (type A1), 66 cases (53.7%) were diagnosed at 17 to 40 years old (type A2), and 55 cases (44.7%) were diagnosed at >40 years old (type A3). The lesions were 52 cases (42.3%) of terminal ileum (L1) type, 20 cases (16.3%) of colon (L2) type, and 51 cases (41.5%) of ileocolon (L3) type. Four cases (3.2%) were non-stenosis and non-penetrating (B1) type, 87 cases (70.7%) were stenosis (B2) type, and 32 cases (26.0%) were penetrating (B3) type. Eighteen patients (14.6%) underwent emergency surgery due to complete intestinal obstruction (10 cases), gastrointestinal perforation (five cases), gastrointestinal bleeding (two cases), and rectovesical fistula complicated with septic shock (one case). One hundred and five patients (85.4%) received selective surgery due to poor conservative treatment effects. 51 cases (41.5%) underwent traditional open surgery and 72 cases (58.5%) underwent laparoscopic surgery. Nineteen patients (15.4%) received temporary or permanent ostomy. The preoperative C reactive protein level of patients with emergency surgery was higher than that of patients undergoing selective surgery ((39.23±24.13) mg/L vs. (11.48±2.68) mg/L), while the levels of plasma albumin (ALB) and pre-ALB were lower than those of patients receiving selective surgery ((29.90±10.60) g/L vs. (38.38±8.30) g/L, (146.00±125.49) mg/L vs. (209.06±61.19) mg/L), and the differences were statistically significant ( Z=9.603, 8.754 and 7.111, all P<0.01). During the follow-up, a total of 23 cases (18.7%) developed postoperative complications, including one case of postoperative intra-abdominal hemorrhage and underwent re-operation (Clavien-Dindo grade Ⅲ complication); four cases of anastomotic leakage after operation; six cases of postoperative paralytic ileus; 11 cases of surgical site infection, all of which were Clavien-Dindo grade Ⅱ complications, and one case of deep venous thrombosis of lower extremity. No patient with severe intraoperative complication was observed, and no patients died during the operation or hospitalization. The postoperative exhaust time of patients was (3.2±1.4) d, the time of open fluid diet was (5.8±0.8) d, the length of hospital stay was (18.0±14.1) d, and the length of postoperative hospital stay was (11.2±8.8) d. Conclusions:The concept of multidisciplinary collaboration should be emphasized in the treatment of CD. Surgical treatment can effectively control the complications and improve the quality of life of patients, but the timing of operation and the choice of surgical methods should be decided prudently after perioperative treatment, multi-disciplinary participated and regulation of the internal environment. The standardized and targeted treatments for the surgical difficulties of inflammatory bowel disease should be conducted.
ABSTRACT
Objective:To investigate the clinical efficacy of gastrojejunal bypass surgery combined with radical gastrectomy following conversion therapy for gastric cancer with outlet obstruction.Methods:The retrospective and descriptive study was conducted. The clinicopatho-logical data of 10 initially unresectable gastric cancer patients with outlet obstruction who were admitted to Ruijin Hospital of Shanghai Jiao Tong University School of Medicine from October 2019 to July 2020 were collected. There were 8 males and 2 females, aged from 41 to 59 years, with a median age of 53 years. Patients underwent 'sandwich therapy' of gastrojejunal bypass surgery combined with gastrectomy following conversion therapy. Observation indicators: (1) gastrojejunal bypass surgery and postoperative situations; (2) conversion therapy and complications; (3) radical gastrectomy and postoperative situations; (4) follow-up. Follow-up using outpatient examinations or telephone interview was conducted to detect postoperative complications, progress-free survival, tumor recurrence and metastasis up to March 2019. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Gastrojejunal bypass surgery and postoperative situations: 10 patients received modified gastrojejunal bypass surgery combined with No.4sb lymph node dissection, without intraoperative serious complications, conversion to laparotomy or death. The operation time, volume of intraoperative blood loss, time to postoperative first flatus, time to liquid diet intake were 73 minutes(range, 60-87 minutes), 33 mL(range,20-110 mL), 3 days(range, 2-6 days), 4 days(range, 4-9 days). One patient had post-operative Clavien-Dindo grade Ⅱ complication of anastomotic bleeding, and was improved after transfusion of blood products. (2) Conversion therapy and complications: of 10 patients, 9 cases received 4 cycles of FLOT regimen. One of the 9 cases was suspended chemotherapy due to Clavien-Dindo grade Ⅱ anastomotic edema after 2 cycles of FLOT regimen. Of 10 patients, there were 6 cases with partial response and 4 cases with stable disease. Of 6 patients with partial response, 4 cases with preoperative cT4b stage were down stage to T4a stage, showing the relationship of tumor with transverse mesentery and pancreatic capsule clearer than the first exploration, 2 cases with preoperative lymph nodes fusion had shrank obviously. Of 4 patients with stable disease, 3 cases were negative for lymph nodes shranking, and the rest 1 case with tumor peritoneal metastasis diagnosed by initial laparoscopy can not be evaluated by imaging examination after chemotherapy. Two of 10 patients had Clavien-Dindo grade I complication of elevated blood glucose during the chemotherapy, which were improved after insulin therapy. (3) Radical gastrectomy and post-operative situations: 10 patients underwent radical resection after conversion therapy. Of 4 cases with stable disease, 3 cases with preoperative lymph nodes fusion showed obvious space between lymph nodes and surrounding tissues at resurgical exploration and received radical resection, 1 case with peritoneal metastasis showed abdominal wall nodelus and omental tuberosity as fibrous scars at resurgical exploration and received radical resection. The operation time, volume of intra-operative blood loss, time to postoperative first flatus, time to initial liquid diet intake, duration of total hospital stay, duration of postoperative hospital stay of 10 patients were 148 minutes(range, 95-195 minutes), 108 mL(range, 100-180 mL), 3 days(range, 2-7 days), 4 days(range, 3-9 days), 11 days(range, 10-21 days), 8 days(range, 7-16 days). Two of 10 patients had perioperative complications. Results of pathological examination of 10 patients showed the number of dissected lymph nodes as 25±6. There were 1 case of stage T1, 5 cases of stage T3, 4 cases of stage T4a. There were 1 case of stage N0, 2 cases of stage N1, 3 cases of stage N2, 4 cases of stage N3. There were 3 cases of tumor regression grade 1a, 1 case of grade 1b, 4 cases of grade 2, 2 cases of grade 3. (4) Follow-up: 10 patients were followed up for 3.9-13.0 months, with a median follow-up time of 6.0 months. The median progression-free survival time of 10 patients was 6.0 months. During the follow-up, 1 case underwent postoperative Clavien-Dindo grade Ⅱ complication of delayed gastric emptying and was improved after symptomatic treatment.Conclusion:The gastrojejunal bypass surgery combined with gastrectomy following conversion therapy for gastric cancer with outlet obstruction is safe and effective.

Objective To investigate the application value of the modified Overlap esophagojejunostomy in totally laparoscopic total gastrectomy (TLTG).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 32 patients who underwent TLTG with modified Overlap esophagojejunostomy in the Ruijin Hospital of Shanghai Jiaotong University School of Medicine between January 2015 and December 2017 were collected.The main points of the modified Overlap method:surgeons stood on the right of patients when digestive tract reconstruction,suspension of left half liver and clockwise rotation before esophageal transection were performed,regulating esophageal opening position and building jejunal loop,and then closing openings using 45.0 mm Endo-GIA and barbed wire.Patients who were diagnosed as Ⅰ A stage by postoperative pathological examination were followed up;patients with lymph node metastases underwent chemotherapy of XELOX regimen and patients in Ⅰ B and Ⅱ stages without lymph node metastases underwent oral S-1 single agent.Observation indicators:(1) surgical and postoperative recovery situations;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative adjuvant therapy,long-term complications and survival up to March 2018.Measurement data with normal distribution were represented as x±s,and measurement data with skewed distribution were described as M(range).Results (1) Surgical and postoperative recovery situations:all the 32 patients underwent successful TLTG and modified Overlap esophagojejunostomy.The operation time,esophagojejunostomy time,volume of intraoperative blood loss,time to initial anal exsufflation,time for initial fluid diet intake,time for initial semifluid diet intake and time of postoperative drainage-tube removal were respectively (227 ± 19) minutes,(22 ±7)minutes,(69±11)mL,(2.1±0.5) days,(3.4±0.4) days,(4.9±0.6) days and (7.5±1.7) days.There was no anastomotic stoma-related complication in 32 patients.One patient was complicated with duodenal stump leakage at 5 days postoperatively and was cured by continuous three-cavity irrigation and conservative treatment.Results of postoperative pathological examination:number of lymph node dissected in 32 patients was 32±4.TNM staging:1,5,7,11,6,1 and 1 patients were detected respectively in Ⅰ A,Ⅰ B,Ⅱ A,Ⅱ B,ⅢA,ⅢB and ⅢC.Duration of postoperative hospital stay of 32 patients was (8.1 ±2.1)days.(2) Follow-up and survival situations:32 patients were followed up for 3-38 months,with a median time of 18 months.During the follow-up,in addition to 1 patient in IA stage,31 patients underwent postoperative adjuvant therapy;patients can take the common soft food,without symptoms of choking and burning feelings,and gastroscopy reexamination was performed at 6 months postoperatively and showed anastomosis patency.One patient died of malignant tumor of maxillary sinus at 9 months postoperatively,1 was detected liver metastasis at 20 months postopeartively and survived with tumor,the other patients had no tumor recurrence or metastasis.Conlusion The modified Overlap esophagojejunostomy is safe and feasible in TLTG,with good short-term outcomes.
ABSTRACT
The development of laparoscopic total mesorectal excision (TME) has been promoting the better understanding of the anatomy in pre-rectal space for surgeons.If the dissection in pre-rectal space was inappropriate and entered into wrong anatomic planes,it would be easier to cause the proper fascia of rectum incomplete and damage the neurovascular bundies,and reduce the radical surgery outcome and induce urinary and sexual dysfunction,finally,affect the prognosis in patients.For surgical approach in pre-rectal space,the author proposed:Based on the related literatures,transecting the Denonvilliers' fascia (DVF) when it's definitely thickened after cutting the peritoneum 0.5 cm anterior to peri-toneal reflection,entering and dissecting in the space between DVF and the proper fascia of rectum,and forming a typical Three-line feature,including the cutting line of peritoneal reflection,the proximal and distal cutting lines of DVF,which can serve as the mark line and mark plane of the entrance to pre-rectal space.Not only this approach can keep the proper completeness of rectal fascia,but also it maximally reserves the DVF.Here,this article discussed the embryonic origins and anatomic characters of DVF,the structures of neurovascular bundles,dissection in the pre-rectal space,surgical approach and clinical outcomes between DVF and laparoscopic TME.
ABSTRACT
Most colorectal surgeries now are carried out as minimally invasive surgery along with the development and application of laparoscopy.However,the surgical imaging system does not meet the progressing requirement of laparoscopic surgeons.Thanks to the advent of three-dimensional (3D) laparoscopy,a more sophisticated surgical scene with realer images of anatomy is provided to surgeons.It makes identification and manipulation easier,so that to shorten the learning curve.Meanwhile,the 3D laparoscopy is not perfect.But authors believe it will finally be used broadly in colorectal surgery with the improvement of the technology.
ABSTRACT
The advancement of laparoscopic surgery serves as a trigger for better understanding of the vascular structure at the inferior border of the pancreas, especially Henle trunk. Henle trunk was first found as convergence to superior mesenteric vein (SMV) conjoined by sub-right colon vein (SRCV) and right gastroepiploic vein (RGEV), but decades later, anterior superior pancreatic duodenal vein (ASPDV) was described as another conjoint vein of Henle trunk. These tributaries are the basic elements of Henle trunk in early years' study. A proper surgical procedure for Henle trunk can significantly reduce the complications of radical right hemi-colectomy (Japanese D3 resection and European complete mesocolic excision, CME). There are four variations of Henle trunk according to the colic venous tributaries that consists the anatomic variations in transverse colon posterior space(TRCPS). These variations are like "fingerprint and pattern" of CME. The recognition and extension of the TRCS is the key to the dissection of Henle trunk in laparoscopic right hemi-colectomy. Our medical center proposed four feasible approaches for extension:(1) hybrid medial approach; (2) completely medial approach; (3)completely medial access by "page-turning" approach; (4) completely medial approach along RCV. Mostly, RCV ended in Henle trunk, and completely medial approach along RCV is efficient to identify the Henle trunk in CME. We suggest dissecting the inferior margin of pancreas along SMV in a bottom-to-top fashion, followed by the dissection of middle colic vessels to reveal the root of Henle trunk. And it's better to dissect Henle trunk by branch rather than at its root for safety. Here, we describe the anatomic characters of Henles trunk, the surgical approach and strategies of Henle trunk in laparoscopic surgery.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical significance of low ligation of inferior mesenteric artery (IMA) and preservation of left colic artery in laparoscopic radical operation for rectal cancer.</p><p><b>METHODS</b>Clinical data of 103 rectal cancer patients undergoing laparoscopic radical operation in Ruijin Hospital from May 2015 to January 2016 were retrospectively analyzed, including 61 cases with preservation of left colic artery (low ligation group, LL group) and 42 cases without preservation of left colic artery (high ligation group, HL group). Clinical conditions during operation and after operation were compared between the two groups.</p><p><b>RESULTS</b>All the patients underwent operation successfully without transferring to laparotomy, intra-operative or post-operative death, and severe intra-operative or anesthetic complications. Age, gender, BMI, ASA score, tumor size and tumor location were not significantly different between the two groups. Four cases(9.5%) in HL group presented ischemic changes in colonic stump during operation, receiving additional colonic resection and no such ischemic changes were found in LL group (P=0.025). The number of harvested lymph node was 16.1±6.8 in HL group and 15.5±7.2 in LL group, number of harvest lymph node in the root of IMA was 4.2±1.7 in HL group with positive rate of 9.5%(4/42) and 4.3±1.7 in LL group with positive rate of 4.9%(3/61), both were not significantly different between the two groups. Lower margin was (2.2±1.4) cm in LL group and (2.8±1.7) cm in HL group, and difference was not significant as well(all P>0.05). There were no significant differences in terms of operation time, blood loss, post-operative complication, recovery of bowel movement and hospital stay. Median follow-up time was 4.5 months(2 to 10 months) and no long-term complications and local recurrence were found.</p><p><b>CONCLUSION</b>Low ligation of IMA with preservation of left colic artery in laparoscopic radical operation for rectal cancer can provide better blood supply for proximal colon and anastomosis, and can achieve same radical clearance of lymph nodes as high ligation without prolonged operation time, which is worth clinical promotion.</p>
