Stoma-site approach single-port laparoscopic versus conventional multi-port laparoscopic Miles's procedure for low rectal cancer: A prospective, randomized controlled trial.

OBJECTIVE: The aim of this study was to compare perioperative outcomes of patients with low rectal cancer after stoma-site approach single-port laparoscopic Miles procedure or conventional multi-port laparoscopic Miles procedure, as well as to evaluate the safety and efficacy of stoma-site approach single-port laparoscopic surgery in low rectal cancer. METHODS: Between September 2020 and September 2021, 51 low rectal cancer patients scheduled for Miles procedure at the Department of Gastrointestinal Surgery of Affiliated Hospital of North Sichuan Medical College were randomly assigned to the single-port laparoscopic surgery group (SPLS) and the multi-port laparoscopic surgery (MPLS) group. The perioperative outcomes were compared between the two groups. RESULTS: In this study, 25 patients underwent SPLS and 26 underwent MPLS. All patients completed the study, and there were no perioperative deaths in either group. Observation indicators such as intraoperative bleeding (39 mL vs. 41 mL), number of lymph nodes (20.12 ± 3.29 vs. 21.84 ± 3.74), average hospital stay (7.15 ± 1.52 vs. 7.64 ± 1.66), and time to flatulence (2.5d vs. 2.5d) showed no significant differences between the SPLS and MPLS groups (p > 0.05). However, the operation duration (180 min vs. 118 min) and perioperative complications showed statistically significant differences between the two groups (p < 0.05). In addition, patients in the SPLS group had significantly higher satisfaction scores than those in the MPLS group (p < 0.05). CONCLUSION: For patients with low rectal cancer requiring Miles surgery, stoma-site approach single-port laparoscopic surgery has comparable safety and efficacy to multi-port laparoscopic surgery.

Total laparoscopic segmental gastrectomy for gastrointestinal stromal tumors: A case report.

BACKGROUND: Gastrointestinal stromal tumors are lesions that originate from digestive tract walls. Several laparoscopic techniques, including local resections, wedge resections and partial gastrectomies, have been used successfully. However, there are no reports on laparoscopic segmental gastrectomy for gastrointestinal stromal tumors. CASE SUMMARY: We present our analysis of 17 patients who were admitted to our hospital from January 2014 to December 2018. All tumors were located in the corpus and antrum of the stomach, close to the lesser curvature of the stomach. The tumors originated from the anterior wall in nine cases and from the posterior wall of the stomach in eight cases. Laparoscopic segmental gastrectomy and end-to-end anastomosis between the proximal and the distal residual stomach were used in all patients. The mean operative time was 112.4 min. The mean length of hospital stay was 4.6 d. Mean operative blood loss was 73.5 mL. There were no leaks, no postoperative bleeding nor need for reintervention. Mean postoperative follow-up was 35.4 mo. The Visick grading index showed fewer gastrointestinal symptoms 3 mo after surgery. Two patients (11.8%) had reflux esophagitis and gastritis. CONCLUSION: Laparoscopic segmental gastrectomy may be a new function-preserving gastrectomy that is feasible for treatment of gastrointestinal stromal tumors that grow in the middle third of the stomach and on the lesser stomach curvature.

Endoscopic titanium clip closure of gastric fistula after splenectomy: A case report.

This report describes a 52-year-old male patient with blunt abdominal traumatic rupture of the spleen due to injuries sustained in an automobile accident. Following splenectomy, the patient developed a gastric fistula. He underwent a long period of conservative treatment, including antibiotics and total parenteral nutrition, which was ineffective. The fistula could not be closed and titanium clip closure using a gastroscopy was then performed in order to close the fistula. After endoscopic therapy and clipping surgery, the patient's general condition improved significantly, and he had no post-procedural abdominal complications. On post-clipping day 6, the gastric fistula was completely closed as shown by X-ray examination of the upper digestive tract. The patient was discharged from hospital and no complications were observed during the six-month follow-up period. Our report suggests that titanium clip closure using endoscopy may be the choice of treatment in patients with a gastric fistula.

Clinical comparison of antrum-preserving double tract reconstruction vs roux-en-Y reconstruction after gastrectomy for Siewert types II and III adenocarcinoma of the esophagogastric junction.

AIM: To explore a reasonable method of digestive tract reconstruction, namely, antrum-preserving double-tract reconstruction (ADTR), for patients with adenocarcinoma of the esophagogastric junction (AEG) and to assess its efficacy and safety in terms of long-term survival, complications, morbidity and mortality. METHODS: A total of 55 cases were retrospectively collected, including 18 cases undergoing ADTR and 37 cases of Roux-en-Y reconstruction (RY) for AEG (Siewert types II and III) at North Sichuan Medical College. The cases were divided into two groups. The clinicopathological characteristics, perioperative outcomes, postoperative complications, morbidity and overall survival (OS) were compared for the two different reconstruction methods. RESULTS: Basic characteristics including sex, age, body mass index (BMI), Siewert type, pT status, pN stage, and lymph node metastasis were similar in the two groups. No significant differences were found between the two groups in terms of perioperative outcomes (including the length of postoperative hospital stay, operating time, and intraoperative blood loss) and postoperative complications (consisting of anastomosis-related complications, wound infection, respiratory infection, pleural effusion, lymphorrhagia, and cholelithiasis). For the ADTR group, perioperative recovery indexes such as time to first flatus (P = 0.002) and time to resuming a liquid diet (P = 0.001) were faster than those for the RY group. Moreover, the incidence of reflux esophagitis was significantly decreased compared with the RY group (P = 0.048). The postoperative morbidity and mortality rates for overall postoperative complications and the rates of tumor recurrence and metastasis were not significantly different between the two groups. Survival curves plotted using the Kaplan-Meier method and compared by log-rank test demonstrated similar outcomes for the ADTR and RY groups. Multivariate analysis of significantly different factors that presented as covariates on Cox regression analysis to assess the survival and recurrence among AEG patients showed that age, gender, BMI, pleural effusion, time to resuming a liquid diet, lymphorrhagia and tumor-node-metastasis stage were important prognostic factors for OS of AEG patients, whereas the selection of surgical method between ADTR and RY was shown to be a similar prognostic factor for OS of AEG patients. CONCLUSION: ADTR by jejunal interposition presents similar rates of tumor recurrence, metastasis and long-term survival compared with classical reconstruction with RY esophagojejunostomy; however, it offers considerably improved near-term quality of life, especially in terms of early recovery and decreased reflux esophagitis. Thus, ADTR is recommended as a worthwhile digestive tract reconstruction method for Siewert types II and III AEG.
