Objective To evaluate the effect of ultrasound guided percutaneous drainage on acute perforation of gastroduodenal ulcer in elderly patients. Methods The clinical features, treatments, and the curative effects of 86 elderly cases (≥65 years) of acute perforation of gastroduodenal ulcer in our hospital between January 2004 and October 2009 were retrospectively analyzed. Twenty-one cases were treated by ultrasound guided percutaneous drainage (drainage group), and 65 cases were treated by exploring operation (operation group). Results Drainage group was cured and had no complications. In 15 patients which accepted recheck one month after drainage, gastroscope showed the ulcer healed in 12 cases， and improved in 3 cases. In operation group, 63 cases were cured and 2 cases died. Compared with the drainage group, there was no significant difference in cure rate (Pgt;0.05). However, 11 patients had operative complications in operation group, which was significantly more than that in the drainage group （Plt;0.05）. In 45 patients which accepted recheck one month after operation, gastroscope showed the ulcer healed in 38 cases， and improved in 7 cases. Conclusion For elderly patients with acute perforation of gastroduodenal ulcer， if the patients do not fit for exploring operation， ultrasound guided percutaneous drainage is proved to be a simple, safe, and effective means.
ObjectiveTo evaluate the curative effect of laparoscopic assisted and open D2 radical resection in treatment of advanced gastric cancer. MethodsThe clinical data of 76 cases performed by laparoscopic assisted D2 radical resection (laparoscopic group) and 104 cases performed by open operation (open group) from October 2010 to October 2012 in our center were retrospective analized.Operation related index, postoperative recovery, and extent of radical resection of tumor of 2 groups were compared. ResultsThe operative time of the laparoscopic group[(192.5±14.8) min]was longer than that open group[(171.5±16.5) min, P < 0.05].But the blood loss, postoperative drainage, length of incision, and hospital stay of the laparoscopic group were significantly less or shorter than those of open group (P < 0.05).There were no significant difference in postoperative complications and extent of radical resection of tumor between the 2 groups (P > 0.05).There were no residual tumor in distal margin and operatiive death case in both 2 groups. ConclusionComparing with open operation, the laparoscopic assisted surgery for advanced gastric cancer could achieve the same clinical outcomes, and obvious advantage of minimal invasion.
Objective To explore the applying value of laparoscopic partial gastrectomy for gastric stromal tumors. Methods The clinical data of 22 patients with gastric stromal tumors between July 2007 and December 2009 in this hospital were analyzed retrospectively. And the laparoscopic resection was performed in all the patients. Results The laparoscopic resections were performed successfully in all the patients, and the tumors were completely resected. The length of operative incision on abdominal wall was 4－6 cm with average 5.3 cm. The mean operation time was 70 min. Postoperative recovery was smooth, no procedure related complications happened. The mean hospital stay was 7.2 d. Specimens of 20 cases were with CD117 (+), and 15 with CD34 (+) by immunohistochemistry. No recurrence or metastasis happened with average follow-up of 13 months (2－23 months). Conclusion Laparoscopic partial gastrectomy for gastric stromal tumors could be performed safely, postoperative recovery quickly and effectively with the advantage of minimal invasiveness.

ObjectiveTo explore the early diagnosis and treatment of acute non-tumor perforation of the back wall of ascending colon. MethodsWe retrospectively analyzed the clinical data of 17 patients with acute non-tumor perforation of the back wall of ascending colon treated between July 2007 and April 2014 in our hospital. Among them, 8 patients who underwent perforation repair combined with abdominal cavity drainage were regarded as the experimental group, and the other 9 patients who underwent operation of right hemicolectomy (or ascending colon resection) were designated as the control group. Clinical indexes and biochemical indexes of both the two groups were compared and analyzed. ResultsAll patients were cured. The operation time[(74.20±12.45), (120.23±15.20) minutes; t=-3.224, P<0.001], the intraoperative blood loss[(40.24±12.20), (80.69±18.98) mL; t=-4.114, P<0.001], the postoperative anal exhaust[(75.62±6.56), (84.54±7.82) hours; t=1.108, P=0.037], the medical expenses[(18.2±5.7) thousand yuan, (26.5±8.3) thousand yuan; t=-5.556, P<0.001], and the hypersensitive C-reaction protein on the third day after operation[(89.45±8.98), (99.85±10.78) mg/L; t=-3.004, P=0.029] in the experimental group and the control group all had significant differences. There was no significant difference between the two groups in the hospital stay time[(9.80±3.16), (9.81±3.20) days; t=1.501, P=0.080]. There was one case of incision infection in the experimental group and one case of fat liquefaction of incision in the control group, and both of them were cured after treatment. ConclusionThe early abdominal sign of perforation of the back wall of ascending colon is not obvious, which can easily lead to misdiagnosis as acute appendicitis. Early diagnosis mainly depends on the clinical symptom, vital sign, blood routine examination and CT examination. Among them, CT findings of gaseous sign behind peritoneum is a definite diagnosis, and operation should be arranged as early as possible. Perforation repair combined with abdominal cavity drainage is preferred due to its advantages of being simple, saving time, less bleeding and lighter traumatic reaction.
Objective To investigate the infection rate and observe the healing courses of the incision after gastrointestinal surgery which was managed by positioning extraperitoneal U-type latex drainage strip. Methods Two hundred patients after abdominal operation were divided into drainage group (n=97) and control group (n=103). Drainage group were treated with positioning extraperitoneal U-type latex drainage strip, while control group were treated with no latex drainage strip. The infection rate of incision, the mean time in hospital and mean time of incision healing were observed. Results The infection rate of drainage group was significantly lower than that of control group 〔7.22% (7/97) vs. 18.45% (19/103), P=0.024〕. The mean time in hospital and the mean time of incision healing in drainage group were significantly shorter than those in control group 〔(8.86±1.48) d vs. (14.12±2.63) d， P=0.000； (8.24±1.02) d vs. (12.32±3.47) d， P=0.000〕. Conclusion The infection rate and the healing course of incision of gastrointestinal surgery could be improved by positioning extraperitoneal U-type latex drainage strip.
ObjectiveTo explore feasibility and advantages of hand-assisted laparoscopic radical resection for remnant gastric cancer. MethodsThe clinical data of 26 patients with remnant gastric cancer who underwent hand-assisted laparoscopic (hand-assisted group, n=13) or open (open group, n=13) radical resection from December 2007 to May 2016 in this hospital were retrospectively analyzed. The perioperative outcomes were compared between these two groups. ResultsThere was no conversion to open surgery in the hand-assisted group. Compared with the open group, the incision length was significantly reduced (P=0.000), the intraoperative blood loss was significantly decreased (P=0.038), postoperative the first anal exhaust time was significantly shortened (P=0.025) in the hand-assisted group. The operation time, the number of lymph nodes dissection, and the incidence of postoperative complications had no statistically significant differences between these two groups (P>0.05). ConclusionThe preliminary results of limited cases in this study show that hand-assisted laparoscopic radical resection for remnant gastric cancer is safe and feasible, it has several advantages including small incisions, mild intraoperative hemorrhage, rapid postoperative recovery, better recent clinical therapeutic outcome and so on as compared with open surgery.
