[Show abstract][Hide abstract] ABSTRACT: To describe the learning curves of hand-assisted laparoscopic D2 radical gastrectomy (HALG) for the treatment of gastric cancer.
The HALG surgical procedure consists of three stages: surgery under direct vision via the port for hand assistance, hand-assisted laparoscopic surgery, and gastrointestinal tract reconstruction. According to the order of the date of surgery, patients were divided into 6 groups (A-F) with 20 cases in each group. All surgeries were performed by the same group of surgeons. We performed a comprehensive and in-depth retrospective comparative analysis of the clinical data of all patients, with the clinical data including general patient information and intraoperative and postoperative observation indicators.
There were no differences in the basic information among the patient groups (P > 0.05). The operative time of the hand-assisted surgery stage in group A was 8-10 min longer than the other groups, with the difference being statistically significant (P = 0.01). There were no differences in total operative time between the groups (P = 0.30). Postoperative intestinal function recovery time in group A was longer than that of other groups (P = 0.02). Lengths of hospital stay and surgical quality indicators (such as intraoperative blood loss, numbers of detected lymph nodes, intraoperative side injury, postoperative complications, reoperation rate, and readmission rate 30 d after surgery) were not significantly different among the groups.
HALG is a surgical procedure that can be easily mastered, with a learning curve closely related to the operative time of the hand-assisted laparoscopic surgery stage.

The aims of this study were to investigate the effects and mechanisms of EA at acupoint Zusanli (ST36) on the plasticity of interstitial cells of Cajal (ICCs) in partial bowel obstruction.

[Show abstract][Hide abstract] ABSTRACT: Three-step hand-assisted laparoscopic D2 radical gastrectomy (HALG) is a modified surgical technique based on hand-assisted laparoscopic surgery (HALS) for the treatment of gastric cancer. This surgical approach is particularly easy and convenient for radical distal gastrectomy. In order to thoroughly understand the advantages of applying "three-step HALG" in distal gastrectomy, our center conducted a retrospective study to analyze data from patients who underwent HALG and laparoscopic-assisted D2 radical gastrectomy (LAG) during the corresponding time period.

[Show abstract][Hide abstract] ABSTRACT: To summarize the experience of lymph node dissection patterns in hand-assisted laparoscopic radical gastrectomy.
One hundred and eleven patients with gastric carcinoma between December 2010 and September 2012 were operated by hand-assisted laparoscopic system designed by us. Clinical data were analyzed retrospectively. The lymph nodes were dissected from left to right together with total tumor resection(reverse lymph nodes scavenge pattern), then digestive tract was reconstructed.
Total gastrectomy, distal gastrectomy and proximal gastrectomy were performed in 57, 46 and 8 cases respectively. Combined cholecystectomy and lateral segment of left liver lobe were needed in 4 and 2 patients respectively, and 1 case underwent combined splenectomy and pancreatic body and tail resection. TNM staging of patients in I(, II(, III(A, III(B, and IIII( were 16, 8, 35, 14, and 38, respectively. Histological type was poorly differentiated in 78 cases, moderate differentiation in 26 cases and good differentiation in 7 cases. The incision length was(6.8±0.3) cm, blood loss was(238.4±113.6) ml, operative time was (171.9±23.3) min, number of removed lymph node was 17.2±5.7, hospital stay was (10.1±3.7) d, postoperative complication rate was 9.0%. One case died during perioperative time.
Hand-assisted laparoscopic D2 radical gastrectomy(reverse lymph nodes scavenge pattern) can avoid the multiple conversion of open-laparoscopic operation model, and is beneficial to the standardization for surgical procedure.

[Show abstract][Hide abstract] ABSTRACT: To evaluate the short-term outcomes after hand-assisted laparoscopic radical gastrectomy.
Between June 2010 and May 2011, a series of 15 patients underwent hand-assisted laparoscopic gastrectomy(HG), 16 patients underwent laparoscopic gastrectomy(LP), and 11 patients underwent open gastrectomy(OP). Short-term outcomes included operative time, blood loss, lymph nodes harvested, and the length of incision were collected after operation.
The operative time was 150-200 min in HG, 180-220 min in LP, and 150-200 min in OP respectively. The time of laparoscopic procedure was 18-58 and 70-100 min respectively. The average incision length was 6.8 cm in HG, 5.6 cm in LP, and 13.5 cm in OP. The average number of lymph nodes harvested was 17.6, 15.1 and 16.4 respectively. The average estimated blood loss was 228 ml, 278 ml, and 427 ml respectively. The mean length of hospital stay was 9.9, 10.8, and 12.4 d. No anastomotic leakage, bleeding, or gastric paralysis were found. One wound infection case was found in OP.
Hand-assisted laparoscopic gastrectomy is in concordance with the standardized treatment protocol for gastric cancer. Lymph node dissection is easier by HG, therefore HG can be an alternative for the radical resection of gastric cancer.

[Show abstract][Hide abstract] ABSTRACT: To investigate the possible reasons and suggest therapeutic plan of stress-induced intestinal necrosis resulting from the severe trauma.
Three patients in our study were trapped inside collapsed structures for 22, 21 and 37 h, respectively. The patients underwent 3-4 operations after sustaining their injuries. Mechanical ventilation, intermittent hemodialysis and other treatments were also provided. The patients showed signs of peritoneal irritation on postoperative days 10-38. Small intestinal necrosis was confirmed by emergency laparotomy, and for each patient, part of the small bowel was removed.
Two patients who all performed 3 operations died of respiratory complications on the first and second postoperative days respectively. The third patient who performed 4 operations was discharged and made a full recovery. Three patients had the following common characteristics: (1) Multiple severe trauma events with no direct penetrating gastrointestinal injury; (2) Multiple surgeries with impaired renal function and intermittent hemodialysis treatment; (3) Progressive abdominal pain and tenderness, and peritoneal irritation was present on post-traumatic days 10-38; (4) Abdominal operations confirmed segment ulcer, necrosis of the small intestine, hyperplasia and stiffness of the intestinal wall; and (5) Pathological examinations suggested submucosal hemorrhage, necrosis, fibrosis and hyalinization of the vascular wall. Pathological examinations of all 3 patients suggested intestinal necrosis with fistulas.
Intestinal necrosis is strongly associated with stress from trauma and post-traumatic complications; timely exploratory laparotomy maybe an effective method for preventing and treating stress-induced intestinal necrosis.
