Objective: To observe the incidence and treatment of radiation rectal injury complicated with anxiety, depression and somatic symptom disorder. Methods: A cross-sectional survey research method was carried out. Patients with radiation rectal injury managed by members of the editorial board of Chinese Journal of Gastrointestinal Surgery were the subjects of investigation. The inclusion criteria of the survey subjects: (1) patients suffered from pelvic tumors and received pelvic radiotherapy; (2) colonoscopy showed inflammatory reaction or ulcer in the rectum. Exclusion criteria: (1) patient had a history of psycho-somatic disease before radiotherapy; (2) patient was unable to use a smart phone, unable to read and understand the questions in the questionnaire displayed on the phone; (3) patient refused to sign an informed consent form. According to the SOMA self-rating scale, PHQ-15 self-rating scale, GAD-7 and PHQ-9 self-rating scale, the electronic questionnaire of "Psychological Survey of Radiation Proctitis" was designed. The questionnaire was sent to patients with radiation rectal injury managed by the committee through the WeChat group. Observational indicators: (1) radiation rectal injury symptom assessment: using SOMA self-rating scale, radiation rectal injury symptom classification: mild group (≤3 points), moderate group (4-6 points) and severe group (> 6 points); (2) incidence of anxiety, depression and physical disorder: using GAD-7, PHQ-9 and PHQ-15 self-rating scales respectively for assessment; (3) correlation of radiation rectal injury symptom grading with anxiety, depression, and somatic symptom disorder. Results: Seventy-one qualified questionnaires were collected, of which 41 (56.9%) were from Guangzhou. Among the 71 patients, 6 were males and 65 were females; the mean age was (55.7±9.3) years old and 48 patients (67.6%) were less than 60 years old; the median confirmed duration of radiation rectal injury was 2.0 (1.0, 5.0) years. (1) Evaluation of symptoms of radiation rectal injury: 18 cases of mild (25.4%), 27 cases of moderate (38.0%), and 26 cases of severe (36.6%). (2) Incidence of anxiety, depression and somatic disorder: 12 patients (16.9%) without comorbidities; 59 patients (83.1%) with anxiety, depression, or somatic disorder, of whom 2 patients only had anxiety, 1 patient only had depression, 9 only had somatic disorder, 2 had anxiety plus depression, 4 had anxiety plus somatic disorder, 2 had depression plus somatic disorder, and 40 had all three symptoms. (3) correlation of radiation rectal injury grading with anxiety, depression, and somatic symptom disorder: as compared to patients in mild group and moderate group, those in severe group had higher severity of anxiety and somatic symptom disorder (Z=-2.143, P=0.032; Z=-2.045, P=0.041), while there was no statistically significant difference of depression between mild group and moderate group (Z=-1.176, P=0.240). Pearson correlation analysis revealed that radiation rectal injury symptom score was positively correlated with anxiety (r=0.300, P=0.013), depression (r=0.287, P=0.015) and somatic symptom disorder (r=0.344, P=0.003). Conclusions: The incidence of anxiety, depression, and somatic symptom disorder in patients with radiation rectal injury is extremely high. It is necessary to strengthen the diagnosis and treatment of somatic symptom disorder, so as to alleviate the symptoms of patients with pelvic perineum pain and improve the quality of life.

Objective: Although single port laparoscopic surgery has achieved good clinical results, many surgeons are discouraged by the difficulties of operation, conflict of instruments, lack of antagonistic traction, and straight-line perspective. Therefore, some surgeons have proposed a single incision plus one hole laparoscopic surgery (SILS+1) surgical method. This study explored the safety and feasibility of SILS+1 for radical resection of colorectal cancer. Methods: A descriptive cohort study was carried out. The clinical data, including the operation, pathology and recovery situation, of 178 patients with colorectal cancer undergoing SILS+1 at Department of General Surgery, Nanfang Hospital, Southern Medical University from March 2018 to January 2019 were prospectively collected and retrospectively analyzed. Clavien-Dindo criteria was used for postoperative complication evaluation and visual analog scale was used for pain standard. Follow-up studies were conducted through outpatient service or telephone and the follow-up period was up to May 2019. Results: A total of 178 patients with colorectal cancer underwent SILS+1, including 111 male patients (62.4%) with an average age of 59 years. Eleven (6.2%) patients received added 1-3 operation ports during operation, and 1 patient was converted to open surgery due to ileocolic artery hemorrhage. The operative time was (135.2±42.3) minutes. The intraoperative blood loss was (34.6±35.5) ml. The number of harvested lymph nodes was 33.1±17.6. The distal margin was (4.7±17.8) cm. The proximal margin was (10.2±5.3) cm. Operation-related complications were observed in 16 patients (9.0%) within 30 days after the operation, of whom 6 had Clavien-Dindo III complications (3.4%). The postoperative pain scores were lower than 3. The average postoperative hospital stay was (5.6±2.6) days. Three patients (1.7%) returned to hospital within 30 days after operation due to intestinal obstruction and infection around stoma. The cosmetic evaluation of all the patients was basically satisfied. Conclusion: SILS+1 is safe and feasible in the treatment of colorectal cancer, and can reduce the postoperative pain.

<p><b>OBJECTIVE</b>To evaluate the risk factors of postoperative complications following D2 radical resection for advanced gastric cancer.</p><p><b>METHODS</b>From June 2004 to May 2011, 483 patients with local advanced gastric cancer who underwent radical gastrectomy with D2 lymph node dissection were enrolled in the study, including 132 patients of LAG (27.3%) and 351 patients of open procedure (72.7%). Clinicopathological data and postoperative complications were reviewed retrospectively. Postoperative complications were classified into overall and severe complications according to Clavien-Dindo Classification. Multivariate logistic model was used to identify risk factors of postoperative complications.</p><p><b>RESULTS</b>The overall incidence of postoperative overall and severe complications and mortality were 12.4% (60/483), 2.5% (12/483) and 0.2% (1/483), respectively. Univariate analysis showed that no significant differences were found in overall and severe complications between the two surgical approaches (13.6% vs. 12.0%, P=0.620; 3.0% vs. 2.3%, P=0.743). Furthermore, multivariate analysis showed that age ≥60 years, preoperative comorbidity and intraoperative blood loss >300 ml were independent risk factors associated with overall postoperative complications. Remarkably, intraoperative blood loss >300 ml was also an independent risk factor for severe postoperative complications.</p><p><b>CONCLUSIONS</b>LAG with D2 lymph node dissection for local advanced gastric cancer is technically feasible and safe. However, the elderly, preoperative comorbidity and increased intraoperative blood loss are associated with elevated risk of complications. Decreased intraoperative bleeding may reduce the potential postoperative complications.</p>

<p><b>OBJECTIVE</b>To evaluate the short-term outcomes and 5-year recurrence, overall survival, and disease-free survival of laparoscopic assisted surgery for colon cancer.</p><p><b>METHODS</b>The clinical and pathologic data were compared between the patients who underwent colectomy during March 2003 to July 2008 and assigned in laparoscopic group (n = 92) and open group (n = 285) according the surgical approach. The 5-year overall survival, disease-free survival, and recurrence rate were analyzed for all patients who were followed-up for more than 36 months in either of the groups.</p><p><b>RESULTS</b>The laparoscopic colectomy was associated with manifested less blood loss (50(50) ml) (Z = -8.292, P < 0.01), early return of bowel function (the evacuation time was (3.0 ± 1.0) days, and the meal time after operation was (4.0 ± 1.3) days) (t = -6.475 and -4.871, P < 0.01), and longer length (cm) of distal resection margin ((10 ± 4) cm vs. (9 ± 4) cm, t = 3.527, P = 0.000). The 5-year overall survival of the laparoscopic group and the open group were 63.6% and 61.8% respectively. The 5-year disease-free survival of the I-III stage patients in the laparoscopic group and the open group were 69.5% and 65.5% respectively, and the local recurrence were 8.7% and 13.6% (all P > 0.05).</p><p><b>CONCLUSION</b>The laparoscopic colectomy for colon cancer is safe in short-term clinical results and non-inferior to the open colectomy in long-term oncological outcomes.</p>

<p><b>OBJECTIVE</b>To analyze the vascular anatomy and complications of the right colon under laparoscope.</p><p><b>METHODS</b>Videotapes of 55 laparoscopic extended right hemicolectomy with D3 lymphadenectomy were reviewed and the anatomic relationship and bleeding vessels were determined.</p><p><b>RESULTS</b>The superior mesenteric vein, superior mesenteric artery, ileocolic artery, and middle colic artery were present in all the patients. The right colic artery was present in 45.5%(25/55) of the patients. The incidence of the gastrocolic venous trunk was 74.5%. The overall incidence of intraoperative bleeding was 43.6%. Vessels in the pre-pancreatic region including the right gastroepiploic artery, the gastrocolic venous trunk, and its tributaries had a higher risk of bleeding than the middle colic vein and artery (16.4% vs. 14.5%). Intraoperative bleeding significantly prolonged the overall operative time and lymphadenectomy time.</p><p><b>CONCLUSIONS</b>The vascular anatomy of the right colon is intricate and variable and laparoscopic extended right hemicolectomy with D3 lymphadenectomy is associated with a high risk of hemorrhage. Understanding the vessels anatomic relationship of the right colon is valuable to decrease vascular complication.</p>

<p><b>OBJECTIVE</b>To investigate the features of intraductal papilloma of the breast in mammography and magnetic resonance imaging (MRI) and assess the diagnostic values of the two imaging modalities.</p><p><b>METHODS</b>Fifteen patients with intraductal papilloma of the breast confirmed surgically and pathologically underwent X-ray examination of the breast, and 11 of them also received enhanced MRI. The imaging findings by mammography and MRI were compared.</p><p><b>RESULTS</b>Enhanced MRI clearly displayed the location and morphology of the intraductal papilloma, and 7 patients showed smooth tumor margins and 2 showed irregular margins. On T(1)WI, the lesions were isointense or slightly hypointense, and appeared isointense or slightly hyperintense on T(2)WI. Some of the intraductal papillomas were seen encapsulated in the dilated ductal. The varying enhancement features of the lesions increased the difficulty in distinguishing from carcinoma. Mammography identified intraductal papillomas only in 2 of the 15 cases (13%) with lesion feature similar to that found by MRI. Fine cluster calcification was found in 1 case.</p><p><b>CONCLUSION</b>MRI can more accurately define the location of the lesion than X-ray. In spite of some resemblance in the MRI findings between intraductal papillomas and breast carcinoma, MRI still serves as a useful diagnostic modality for intraductal papilloma that shows some characteristic findings.</p>

<p><b>OBJECTIVE</b>To observe the effect of laparoscopy-assisted and open distal gastrectomies on the perioperative levels of C-reactive protein (CRP) and visceral proteins in patients with gastric cancer.</p><p><b>METHODS</b>T Fifty-three patients with gastric cancer were randomized into two groups to receive laparoscopic surgery (n=26) or open surgery (n=27). The CRP levels were measured preoperatively and at 1, 2, 3 and 7 days after the operation. The levels of the visceral proteins including albumin (ALB), prealbumin (PRE), transferrin (TRF) and retinal-binding protein (RbP) were assayed before and at 3 and 7 days after the operation.</p><p><b>RESULTS</b>Compared with the preoperative levels, the CRP levels in both groups were significantly increased on days 1, 2, and 3 after the operation (P<0.05), with the highest level occurred on day 2 postoperatively. The postoperative CRP levels were significantly lower in the laparoscopic group than in the open surgery group (P<0.01). The levels of ALB, PRE, TRF, and RbP were significantly decreased after operation in both groups (P<0.01) without significant differences between the two groups (P>0.05).</p><p><b>CONCLUSION</b>Compared with open surgeries, laparoscopy-assisted distal gastrectomy for gastric cancer causes minimal surgical trauma and mild inflammatory responses to allow the recovery of the levels of the visceral proteins.</p>

<p><b>OBJECTIVE</b>To investigate the effect of laparoscopic-assisted resection of rectal carcinoma on perioperative levels of C-reactive protein (CRP), immunoglobulins(Ig) and complements.</p><p><b>METHODS</b>Fifty-four patients with rectal carcinoma were divided into laparoscopic group (n=26) and open operation group(n=28) according to the patients' will. C-reactive protein (CRP), IgG, IgA, IgM, C(3), C(4) and CH(50) of peripheral blood were assayed preoperatively and on the 1st, 2nd, 3rd and 7th day postoperatively.</p><p><b>RESULTS</b>Compared with the preoperative period, the CRP levels in both groups were significantly increased on the 1st, 2nd, and 3rd day(P<0.01) and peaked on the 2nd day postoperatively. The postoperative CRP levels were significantly lower in the laparoscopic group than those in the open operation group(P<0.01). After operation, the immunoglobulin levels were significantly decreased in both groups(P<0.01), and there were no significant differences in IgG and IgM. The levels of C(3), C(4) and CH(50) were significantly decreased after operation in both groups(P<0.05) and returned to the preoperative levels during postoperative 48-72 hours in laparoscopic group.</p><p><b>CONCLUSION</b>Laparoscopic-assisted resection of rectal carcinoma results in less wound, lower levels of stress response, and less effect on immune function compared to open surgery, which recovers the immune function of patients more rapidly after operation.</p>
