ObjectiveTo compare the results of laparoscopic-endoscopic cooperative resection and open surgery for gasric stromal tumor. MethodsFrom January 2010 to March 2015, the clinical data of 56 cases undergoing laparoscopic resection for gasric stromal tumor and 53 cases of traditional operation selected during the same period were retrospectively compared. ResultsThere was no significant difference between two groups in patient's gender, age, body weight, size of tumor, tumor staging, method of operation, intraoperative conditions, postoperative overall complications, local recurrence, and distant metastasis. There were 1 case with the rupture of tumor and 1 case of open surgery transforming in laparoscopic group. In another group, there was the absence of the rupture of tumors. There was no mortality, stomach bleeding, stenosis or leakage occurred between two groups. In laparoscopic group, there were less operative blood loss and abdominal drainage, shorter time of postoperative anal exhaust time, fewer anodyne, a reduction of hospital stay than in convention operation group.However, laparoscopic resection required greater hospital costs and longer operative time. There were significant differences between two groups (P < 0.05). Conciusions With advantages of less blood loss and quicker recovery as compared to conventional operation. Laparoscopic-endoscopic cooperative resection for gasric stromal tumor has similar effect when it is performed by well selection of cases, skilled surgeon with experience on open resection for surgical treatment of gastric stromal tumor.
Objective To investigate the effect of laparoscopy combined with choledochoscopy on common bile duct (CBD) stones with primary suture of the CBD. Methods Totally 523 patients of gallbladder stone companied with CBD stones or choledochectasia (diameter ≥0.8 cm) from September 1998 to December 2008 were retrospectively analyzed. Results The primary suture of the CBD incision was successfully performed in 487 patients. The CBD stones were completely removed during the operation in 400 patients. Nothing was found in 87 cases. In 10 cases conversion to open surgery were performed and in 26 cases the T tube drainage was put into the CBD in choledocholithotomy. Average operative time was 90 min and average bleeding volume was 50 ml. All patients took food at 24 h, returned general activity on 2-3 d and discharged on 5 d after operation. Postoperative biliary leakage occurred in 29 cases with drainage average volume of 35 ml/d and continued 1-6 d, which were cured by non-operation therapy. Conclusions The primary suture of the CBD during the laparosocopy combined with choledochosopy in choledocholithotomy is a safe and effective operation with less invasion, less pain and quicker recovery. CBD incision suture without T tube drainage can be done when CBD stones are cleared completely and no stenosis is found in extrahepatic bile duct.
Objective To explore the important role of preperitoneal space in laparoscopic transabdominal preperitoneal （TAPP） and totally extraperitoneal （TEP） hernia repair. Methods The clinical data of 66 patients （78 sides） performed laparoscopic TAPP and TEP hernia repair from January 2008 to April 2011 in this hospital were analyzed retrospectively. Results TAPP hernia repair were performed in 16 cases （20 sides），TEP hernia repair were performed in 50 cases （58 sides）. Three cases of TEP hernia repair transferred to TAPP hernia repair. The unilateral operation time was （86.92±36.38） min，intraoperative bleeding was （6.08±3.43） ml. Postoperative complication rate was 16.7% （11/66），including 3 cases of postoperative serum swelling，3 cases of temporary paraesthesia of nerve feeling in the repair area，2 cases of scrotum emphysema，2 cases of urinary retention，and 1 case of intestinal obstruction. There were 2 cases of recurrence. The hospital stay was （4.52±0.99） d. The return to activities and working time was （10.32±1.86） d after discharge. Sixty-six cases were followed up for （18.56±1.96） months （range 1-38 months），the patch infection，chronic pain，and testicular atrophy complications were not been observed. Conclusions Acquainting and mastering laparoscopic preperitoneal space and its important structure are the key to avoid intraoperative and postoperative complications of laparoscopic inguinal hernia repair.
【Abstract】Objective To investigate the effects and advantages of laparoscopic hernioplasty for hernia. Methods From June 1995 to June 2005, 222 patients with hernia were treated with laparoscopy. Transabdominal preperitoneal hernia repair (TAPP) were performed in 166 patients. Totally extraperitoneal hernia repair(TEP) were performed in 25 patients. Closure of the internal orifice of hernia was performed in 21 patients. Furthermore, incisional hernia in 2 patients, diaphragmatic hernia in 1 patient and mesenteric hernia in 1 patient were performed by laparoscopic hernioplasty and 6 patients with hernia of oesophagus finestra performed hernioplasty combined collapse gastric fundus with laparoscopy. In this series 45 patients associated with other abdominal disease were simultaneously treated with laparoscopy. Results All cases were operated successfully. The span of operation reduration was 42.5 min 〔(10～180 min)〕. The average length of postoperative hospital stay were 4.6 days. There was one early failure owing to the use of too small a piece of mesh.Conclusion The results indicate that mesh repair of hernias is a satisfactory technique with a low recurrence rate and a low major complication rate.
ObjectiveTo investigate the effectiveness of retroperitoneal laparoscopic approach combined with anterolateral mini-incision for lumbar spine tuberculosis. MethodsA retrospective analysis was made on the cl inical data of 22 patients with lumbar spine tuberculosis undergoing focus clearance, fusion, and internal fixation by retroperitoneal laparoscopic approach combined with anterolateral mini-incision between June 2006 and June 2012. There were 14 males and 8 females, with an average age of 42.6 years (range, 26-57 years) and with a mean disease duration of 7.3 months (range, 3-10 months). There were 17 patients with single-level spinal tuberculosis (L1, 2 in 3, L2, 3 in 6, L3, 4 in 4, L4, 5 in 2, and L5 in 2) and 5 patients with double-level spinal tuberculosis (L1-3 in 2 and L2-4 in 3). The preoperative Cobb's angle of lumbar spine was 5-28° (mean, 20°). In 6 patients having compression symptom, 4 cases were rated as grade D and 2 as grade C according to Frankel classification. The operative time, intraoperative blood loss, and postoperative complications were recorded. At last follow-up, the neurologic function was assessed according to Frankel grade, the Cobb's angle after operation was measured on lumbar lateral X-ray film; the efficacy was evaluated according to Nakai criteria, and the fusion was evaluated according to Suk criteria. ResultsAll operations were successfully completed. The operation time was 110-250 minutes (mean, 140 minutes), and intraoperative blood loss was 120-280 mL (mean, 180 mL). The symptoms of femoral nerve injury and sympathetic nerve injury occurred in 1 case respectively and was relieved at 1-3 weeks after operation. All incisions healed by first intention. The patients were followed up 16-50 months (mean, 21 months). During the follow-up period, no loosening or breakage of implants and no tuberculosis recurrence were found. At last follow-up, the nerve function was recovered to grade E in the others except 1 case at grade D. The Cobb's angle was 2-16° (mean, 7.8°). According to Nakai criteria for efficacy evaluation, the results were excellent in 9 cases, good in 10 cases, and fair in 3 cases, with an excellent and good rate of 86.4%. The bony fusion rate was 95.5% (21/22) according to Suk criteria. ConclusionRetroperitoneal laparoscopic approach combined with anterolateral mini-incision for lumbar spine tuberculosis is a safe and effective approach with minimal invasion and less complications.
ObjectiveTo investigate the value of different minimally invasive surgical techniques, stent placement, laparoscopic surgery, and sustained-releasing 5-fluorouracil, in solving intestinal obstruction due to colorectal cancer. MethodsFrom May 2000 to May 2010, total 68 patients with obstructed colorectal cancers in three centers were treated in two ways in terms of the stage: The first, patients with resectable tumors underwent colorectal stent placement as a ‘bridge to surgery’ guided by enteroscope under X-ray. After clinical decompression and bowel preparation, laparoscopic radical resection was performed. The second, patients with unresectable tumors underwent rectal stent placement just for palliation. Sustained-releasing 5-fluorouracil was implanted into the local cancerous intestinal tract through stent walls. ResultsFifty-one of 52 patients underwent laparoscopic radical resection successfully following stent placement, while one failed and died during follow-up 93 d postoperatively. Forty patients with successful laparoscopic surgery were followed up in 3 to 36 months (with an average of 15 months) without tumor planting in the incision, postoperative local recurrence or anastomotic stricture. Fifteen unresectable patients and one high-risk, intolerable patient underwent rectal stent placement and implantation of sustained-releasing 5fluorouracil. During follow-up 3 to 24 months (with an average of 14 months), 11 died, who survived for (350±222) d (range 101-720 d), and 5 were still alive for 3 to 13 months (with an average of 9 months) without intestinal obstruction. ConclusionsLaparoscopic surgery combined with stent placement is an effective and safe procedure for resectable obstructed colorectal cancer. For unresectal obstructed rectal cancer, rectal stent placement combined with sustained-releasing 5-fluorouracil can prolong survival time avoiding colostomy.
Objective To investigate the clinical therapeutic effects of two types of vaginoplasty. Methods From January 1996 to March 2005, 63 patients wih the congenital absence of the vagina were treated by two types of vaginoplasty. Of the 63 patients, 37 underwent vaginoplasty using the amnion and 26 underwent an improved laparoscopic Vecchitti operation. The durations ofthe operation and hospitalization, as well as the blood loss were compared between the two types of vaginoplasty. The vaginal moulds were improved during the operations. Results According to the follow-up for 2 months to 4 years in the 35 patients. Compared with vaginoplasty using the amnion, vaginoplasty by an improved laparoscopic Vecchitti operation had advantages of significantly shorter surgical duration, shorter hospitalization, and less blood loss (Plt;0.05). After the operations, the artificial vagina of all the 63 patients could hold a speculum and the mucosa appeared so soft and smooth with normal lubrication. The married patients were satisfied with the intercourse. However, after vaginoplasty using the amnion, an infection of the amnion occurred in 3 patients, scar contracture in 2 patients, one of whom underwent scar incision 13 months after operation with a success; but the other refuse to accept another operation. But the improved laparoscopic Vecchitti operation achieved a success in the patients without any infectionor scar contracture, according to the 2 month-2.5 years follow-up. Conclusion The improved laparoscopic Vecchitti operation is a preferred procedure of constructing a vagina for the patients suffering from the congenital absence of the vagina.
Objective To explore surgical technique and clinical outcome of transabdominal preperitoneal hernia repair (TAPP) and totally extraperitoneal hernia repair (TEP) in inguinal hernia repair. Methods 〗The clinical data of 23 patients underwent laparoscopic herniorrhaphy were retrospectively analyzed. Nine patients were underwent TAPP, and 14 patients underwent TEP. Results 〗None of patients was changed to open operation. Only one patient of TEP was changed to TAPP. Average operative time was (82.1±40.6) min. Blood loss was (5.7±3.0) ml. Disruption of peritoneum happened to 2 patients underwent TEP. The rate of postoperative complications was 21.7% (5/23), which included serum swelling (1 case), scrotal emphysema (2 cases), transient neurapraxia in the area of repair (1 case) and urinary retention (1 case). No chronic pain, foreign body sensation and infection were found. Average hospitalization after operation was (4.3±0.9) d. No recurrence was observed during a follow-up period of 1-15 months. Conclusion 〗Laparoscope herniorrhaphy is safe due to lower recurrence and complications. It also has the advantages of slight pain and rapid recovery.
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 evaluate the clinical experience and skills of laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection in order to spread and popularize this kind of operation. Methods Under general anesthesia, 32 patients (42 sides) with inguinal hernias were repaired by laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a dissection balloon from August 2005 to December 2007. Results All of operations were successfully performed. The operative time was 60-120 minutes, the blood loss was 20-60 ml, and the length of postoperative hospitalization was 3 days. All cases were followed up for 8 to 18 months and found no recurrence. Conclusion Laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection is feasible, reliable and effective, offering a low recurrence rate, while its price is higher than tension-free herniorrhaphy by traditional method.
