METHODS: Prospectively collected data from 293 consecutive patients with acute appendicitis were studied. These comprised of 165 patients who underwent conventional appendectomy and 128 patients treated laparoscopically. The two groups were compared with respect to operative time, length of hospital stay, postoperative pain, complication rate and cost. RESULTS: There were no statistical differences regarding patient characteristics between the two groups. Conversion to laparotomy was necessary in 2 patients (1.5%). Laparoscopic appendectomy was associated with a shorter hospital stay (2.2 d vs 3.1 d, P = 0.04), and lower incidence of wound infection (5.3% vs 12.8%, P = 0.03). However, in patients with complicated disease, intra-abdominal abscess formation was more common after laparoscopic appendectomy (5.3% vs 2.1%, P = 0.002). The operative time and analgesia requirements were similar in the two groups. The cost of treatment was higher by 370 € in the laparoscopic group. CONCLUSION: Laparoscopic appendectomy is as safe and effi cient as open appendectomy, provided surgical experience and equipment are available.展开更多

Three cases with nonparasitic splenic cysts are presented: two epithelial and one pseudocyst. All cases had an atypical symptomatology, consisted mainly of fullness in the left upper abdomen and a palpable mass. Preoperative diagnosis was established with ultrasonography and computerized tomography. Two cases with large cysts located in the splenic hilum were treated with open complete splenectomy. The most recent case, a pseudocyst, was managed laparoscopically with partial cystectomy. All cases did not have any problems or recurrence during follow-up. Laparoscopic partial cystectomy is an acceptable procedure for the treatment of splenic cysts, because it cures the disease preserving the splenic tissue. Complete splenectomy is reserved for cases in which cyst excision cannot be done otherwise.展开更多

Restoration of bowel continuity is possible in most cases, without compromise of cancer clearance. Re-anastomosis can be performed with stapled, transabdominal hand-sewn or coloanal pull- through techniques. However after a direct (straight) anastomosis of the colon to the distal rectum/anus, up to 33% of patients have 3 or more bowel movements/ d; some can be troubled with up to 14 stools a day. Construction of a 6-cm colonic J-pouch is likely to cause some reversed peristalsis which improves postoperative bowel frequency without causing neo-rectum evacuation problems. Colonic J-pouch-anal anastomosis patients have a median of 3 bowel movements a day compared with a median of 6 a day for straight anastomoses, at 1 year after surgery. In the longer term, bowel adaptation may enable the function after a straight anastomosis to approximate that of a colonic J-pouch-anal anastomosis. This probably depends in the former, upon whether the more rigid sigmoid colon or more distensible descending colon is used. An additional advantage of the colonic J-pouch-anal anastomosis is the lower risk of anastomotic complications. A more vascularized side-to- end (colonic J-pouch-anal) anastomosis is likely to heal better than an end-to-end (straight) anastomosis. Where the pelvis is too narrow for a bulky colonic J-pouch anal anastomosis, a coloplasty-anal-anastomosis is an option. The latter results in postoperative bowel function comparable with the colonic J-pouch. However, the risk of anastomotic complications is higher possibly related to its end-to-end anastomotic configuration. Laparoscopic techniques for accomplishing all the above are being proven to be effective. Restorative surgery for rectal cancer can be safely and effectively performed withmethods to improve bowel function very acceptably; the future advances are likely in laparoscopy.展开更多

Methods Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. The study group included 21 patients with shock and intraperitoneal hemorrhage more than 1000 mL, and control group included 194 patients, hemodynamically stable, with blood loss less than 1000 mL. Clinical data of perio-perative periods in two groups were retrospectively analyzed. Results All patients were tubal pregnancies. The occurrence rate of tubal rupture was higher in study group than in control group (80.95% vs. 15.98%, P < 0.001). Intraabdominal blood loss was significantly higher in study group than in control group (1900 mL vs. 300 mL, P < 0.001), and autologous blood transfusions were given to 95.24% and 9.3% of patients in study and control group, respectively (P < 0.001). Laparoscopic salpingectomy was performed on 85.7 % and 50.5% of patients in study and control group (P < 0.001). The operative time was somewhat longer in study group than that in control group (60 minutes vs. 45 minutes), but with no significant difference. All patients had no perioperative complications. Conclusion Operative laparoscopy in patients with hopovolemic shock can be safely and effectively performed by experi-enced laparoscopists with the aid of optimal anesthesia, advanced cardiovascular monitoring, and autologous blood transfusion.展开更多

The hospitalization time, hospitalization costs, operation time, operative complications and post-operative liver functions of the two groups of patients were studied.RESULTS: The operation time and post-operative liver functions of the two groups of patients had no significant differences, while the hospitalization time, hospitalization costs and operative complications of the laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration in the common bile duct group were significantly lower than those in the traditional open operation group.CONCLUSION: For patients with gallstones in the left lobe of liver and in the common bile duct, laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct can significantly shorten the hospitalization time, reduce the hospitalization costs and the post-operative complications,without prolonging the operation time and bringing about more liver function damages compared with traditional open operation. This kind of operation has more advantages than traditional open operation.展开更多

To investigate retrospectively the complications and associated factors of gynecological laparoscopies. Methods. 1 769 laparoscopic surgeries were carried out from January 1994 to October 1999 at our department. The procedures included 1421 surgeries of ovary and tube, 52 myomectomies and 296 cases of laproscopic-assisted vaginal hysterectomy (LAVH). A total of 312 patients had a history of prior laparotomy (176%). Results. Complications occured in 34 cases, the overall complication rate was 192%. Unintended laparotomies occured in 6 cases(034%). 12 complications were associated with insertion of Veress needle or trocar and creation of pneumoperitoneum, including 5 severe emphysema and 7 vascular injuries, this figure represents 353% of all complications of this series. Five intraoperative complications (147%) occured during the laparoscopic surgery (3 severe bleedings, one bladder injury and one skin burn of leg caused by damaged electrode plate), laparotomy was required in four of these cases. Seventeen complications occured during postoperative stage: 2 intraperitoneal hemorrhages needing laparotomy, 2 bowel injuries, 4 nerve paresis and 9 febrile morbidities. Conlusions. Operative gynecologic laparoscopy is associated with acceptable morbidity rate, but can not be overlooked. Complication rate seems to be higher in advanced procedures such as LAVH.展开更多

Methods: From November 2006 to May 2008, 221 patients with esophageal cancer were enrolled in this study, prospective randomized in two groups. 111 patients were performed the VATS technique (Experimental group), whereas in the other 110 patients esophagectomy was adopted by thoracotomy (Control group). Results: The time consuming of Experimental group was 272.3 min in average with a standard deviation(std) of 57.9, and it was 218.7 min in average with std of 91.0 in the control group (P=0.000). The operative blood loss was 219.7±194.4 mL in the Experimental group, compared with 590.0±324.4 mL in the control group, with significant difference (P=0.000). Postoperative hospital stay of Experimental group was 9.6±1.7d, and it was 11.4±2.3d in the control group (P=0.000). There was no-delayed union of incision in the Experimental group, but 6.36% in the control group (P=0.007). The disorder of gastric emptying occurred 0.9% in the Experimental group, whereas 6.4% in the Control group. There was no significant difference in survival curves and rates (P=0.555). Conclusion: There were several advantages of VATS technique, such as reduced hemorrhage, better recovery, few complications, and great number of lymph node dissection, although there was no significant difference in long-term survival rate. Thus the VATS combined with laparoscopy technique was worthy of generalization in esophageal surgery with good prospects.展开更多

She was admitted to our hospital with rectal bleeding and constipation. We performed several workups. Colonoscopy and endoscopic ultrasonography showed sigmoid colon stenosis caused by submucosal tumor, and magnetic resonance imaging revealed a sigmoid colon tumor displaying signal hy- pointensity on both T1- and T2-weighted imaging. However, colonoscopic ultrasonography-assisted needle aspiration biopsy could not specify tumor characteristics. From these examinations, the lesion was diagnosed as sigmoid colon endometriosis and laparoscopy-assisted sigmoidectomy was performed. Pathological diagnosis from the resected specimen was identical to preoperative diagnosis, i.e., colonic endometriosis. Since differential diagnosis of intestinal endometriosis seems difficult, a cautious preoperative diagnosis is required to select treatments including minimally invasive surgery.展开更多

The appropriate selection criteria are still under investigation.Technical considerations are playing an important role for the complexity of both diseases.展开更多

In contrast, laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm. While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach, whether the same oncologic clearance, specifically an adequate TME can be obtained is of concern. The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes. The data from 8 RCTs, 3 metaanalyses, and 2 Cochrane Database of Systematic Reviews was reviewed. Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss, earlier return of bowel function, and shorter hospital length of stay. Concerns that laparoscopic rectal cancer surgery compromises short-term oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature. Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.展开更多

Methods Data from 70 cases of poorly differentiated EGC treated with surgery were collected.The association between clinicopathologic factors and the presence of LNM was retrospectively analyzed by univariate and multivariate logistic regression analyses. Results Univariate analysis showed that tumor size,depth of invasion,and lymphatic vessel involvement(LVI) were the significant and independent risk factors for LNM(all P<0.05).The LNM rates were 6.9%,45.5%,and 60.0%,respectively.There was no LNM in 25 patients without the above three risk factors. Conclusions Laparoscopic surgery is a sufficient treatment for intramucosal poorly differentiated EGC if the tumor is less than or equal to 2.0 cm in size and when LVI is absent upon postoperative histological examination.展开更多

The m...The "Center of Excellence" concept has been employed in healthcare for several decades. This concept has been adopted in several disciplines; such as bariatric surgery, orthopedic surgery, diabetes and stroke. The most successful model in surgery thus far has been the bariatric program, with a very extensive network and a large prospective database. Recently, the American As-sociation of Gynecologic Laparoscopists has introduced this concept in gynecologic surgery. The "Center Of Excellence in Minimally Invasive Gynecology" (COEMIG) designation program has been introduced with the goals of increasing safety and efficiency, cutting cost and increasing patient awareness and access to mini-mally invasive surgical options for women. The program may harbor challenges as well, such as human and fnancial resources, and diffculties with implementation and maintenance of such designation. This commen-tary describes the COEMIG designation process, along with its potential benefits and possible challenges. Though no studies have been published to date on the value of this concept in the feld of gynecologic surgery, we envision this commentary to provoke such studies to examine the relative value of this new program.展开更多

文摘Objective To evaluate the feasibility and safety of operative laparoscopy for ectopic pregnancy with hypovolemic shock. Methods Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. The study group included 21 patients with shock and intraperitoneal hemorrhage more than 1000 mL, and control group included 194 patients, hemodynamically stable, with blood loss less than 1000 mL. Clinical data of perio-perative periods in two groups were retrospectively analyzed. Results All patients were tubal pregnancies. The occurrence rate of tubal rupture was higher in study group than in control group (80.95% vs. 15.98%, P < 0.001). Intraabdominal blood loss was significantly higher in study group than in control group (1900 mL vs. 300 mL, P < 0.001), and autologous blood transfusions were given to 95.24% and 9.3% of patients in study and control group, respectively (P < 0.001). Laparoscopic salpingectomy was performed on 85.7 % and 50.5% of patients in study and control group (P < 0.001). The operative time was somewhat longer in study group than that in control group (60 minutes vs. 45 minutes), but with no significant difference. All patients had no perioperative complications.

Five intraoperative complications (147%) occured during the laparoscopic surgery (3 severe bleedings, one bladder injury and one skin burn of leg caused by damaged electrode plate), laparotomy was required in four of these cases. Seventeen complications occured during postoperative stage: 2 intraperitoneal hemorrhages needing laparotomy, 2 bowel injuries, 4 nerve paresis and 9 febrile morbidities. Conlusions. Operative gynecologic laparoscopy is associated with acceptable morbidity rate, but can not be overlooked. Complication rate seems to be higher in advanced procedures such as LAVH.
文摘AIM:To evaluate the impact of incidental gallbladder cancer on surgical experience.METHODS:Between 1998 and 2008 all cases of cholecystectomy at two divisions of general surgery,one university based and one at a public hospital,were retrospectively reviewed.Gallbladder pathology was diagnosed by history,physical examination,and laboratory and imaging studies [ultrasonography and computed tomography(CT)].Patients with gallbladder cancer(GBC) were further analyzed for demographic data,and type of operation,surgical morbidity and mortality,histopathological classification,and survival.Incidental GBC was compared with suspected or preoperatively diagnosed GBC.The primary endpoint was diseasefree survival(DFS).The secondary endpoint was the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention.RESULTS:Nineteen patients(11 women and eight men) were found to have GBC.The male to female ratio was 1:1.4 and the mean age was 68 years(range:45-82 years).Preoperative diagnosis was made in 10 cases,and eight were diagnosed postoperatively.One was suspected intraoperatively and confirmed by frozen sections.The ratio between incidental and nonincidental cases was 9/19.The tumor node metastasis stage was:pTis(1),pT1a(2),pT1b(4),pT2(6),pT3(4),pT4(2);five cases with stageⅠa(T1 a-b);two with stageⅠb(T2 N0);one with stage Ⅱa(T3 N0);six with stage Ⅱb(T1-T3 N1);two with stage Ⅲ(T4 Nx Nx);and one with stage Ⅳ(Tx Nx Mx).Eighty-eight percent of the incidental cases were discovered at an early stage(≤Ⅱ).Preoperative diagnosis of the 19 patients with GBC was:GBC with liver invasion diagnosed by preoperative CT(nine cases),gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum(one case),porcelain gallbladder(one case),gallbladder adenoma(one case),and chronic cholelithiasis(eight cases).Every case,except one,with a T1b or more advanced invasion underwent Ⅳb + Ⅴ wedge liver resection and pericholedochic/hepatoduodenal lymphadenectomy.One patient with stage T1b GBC refused further surgery.Cases with Tis and T1a involvement were treated with cholecystectomy alone.One incidental case was diagnosed by intraoperative frozen section and treated with cholecystectomy alone.Six of the nine patients with incidental diagnosis reached 5-year DFS.One patient reached 38 mo survival despite a port-site recurrence 2 years after original surgery.Cases with non incidental diagnosis were more locally advanced and only two patients experienced 5-year DFS.CONCLUSION:Laparoscopic cholecystectomy does not affect survival if implemented properly.Reoperation should have two objectives:R0 resection and clearance of the lymph nodes.
文摘Objective: The aim was to evaluate the best intra-thoracoscopic surgery technique between video-assisted thoracic surgery (VATS) combined with laparoscopy and right open transthoracic esophagectomy, in patients with esophageal cancer. Methods: From November 2006 to May 2008, 221 patients with esophageal cancer were enrolled in this study, prospective randomized in two groups. 111 patients were performed the VATS technique (Experimental group), whereas in the other 110 patients esophagectomy was adopted by thoracotomy (Control group). Results: The time consuming of Experimental group was 272.3 min in average with a standard deviation(std) of 57.9, and it was 218.7 min in average with std of 91.0 in the control group (P=0.000). The operative blood loss was 219.7±194.4 mL in the Experimental group, compared with 590.0±324.4 mL in the control group, with significant difference (P=0.000). Postoperative hospital stay of Experimental group was 9.6±1.7d, and it was 11.4±2.3d in the control group (P=0.000). There was no-delayed union of incision in the Experimental group, but 6.36% in the control group (P=0.007). The disorder of gastric emptying occurred 0.9% in the Experimental group, whereas 6.4% in the Control group. There was no significant difference in survival curves and rates (P=0.555). Conclusion: There were several advantages of VATS technique, such as reduced hemorrhage, better recovery, few complications, and great number of lymph node dissection, although there was no significant difference in long-term survival rate. Thus the VATS combined with laparoscopy technique was worthy of generalization in esophageal surgery with good prospects.
文摘We present a female patient with sigmoid colon endometriosis who was diagnosed correctly preoperatively and underwent minimally invasive surgery. She was admitted to our hospital with rectal bleeding and constipation. We performed several workups. Colonoscopy and endoscopic ultrasonography showed sigmoid colon stenosis caused by submucosal tumor, and magnetic resonance imaging revealed a sigmoid colon tumor displaying signal hy- pointensity on both T1- and T2-weighted imaging. However, colonoscopic ultrasonography-assisted needle aspiration biopsy could not specify tumor characteristics. From these examinations, the lesion was diagnosed as sigmoid colon endometriosis and laparoscopy-assisted sigmoidectomy was performed. Pathological diagnosis from the resected specimen was identical to preoperative diagnosis, i.e., colonic endometriosis. Since differential diagnosis of intestinal endometriosis seems difficult, a cautious preoperative diagnosis is required to select treatments including minimally invasive surgery.
文摘A cavernous hemangioma of the cecum is a rare vascular malformation but is clinically important because of the possibility of massive bleeding.We report a case of a large cavernous hemangioma with pericolic inf iltration in the cecum which was removed successfully using minimally invasive surgery.
文摘Inflammatory bowel diseases are an ideal indication for the laparoscopic surgical approach as they are basically benign diseases not requiring lymphadenectomy and extended mesenteric excision;well-established surgical procedures are available for the conventional approach.Inflammatory alterations and fragility of the bowel and mesentery,however,may demand a high level of laparoscopic experience.A broad spectrum of operations from the rather easy enterostomy formation for anal Crohn’s disease(CD)to restorative proctocolectomies for ulcerative colitis(UC)may be managed laparoscopically.The current evidence base for the use of laparoscopic techniques in the surgical therapy of inflammatory bowel diseases is presented.CD limited to the terminal ileum has become a common indication for laparoscopic surgical therapy.In severe anal CD, laparoscopic stoma formation is a standard procedure with low morbidity and short operative time.Studies comparing conventional and laparoscopic bowel resections,have found shorter times to first postoperative bowel movements and shorter hospital stays as well as lower complication rates in favour of the laparoscopic approach.Even complicated cases with previous surgery,abscess formation and enteric fistulas may be op-erated on laparoscopically with a low morbidity.In UC, restorative proctocolectomy is the standard procedure in elective surgery.The demanding laparoscopic approach is increasingly used,however,mainly in major centers; its feasibility has been proven in various studies.An increased body mass index and acute inflammation of the bowel may be relative contraindications.Short and longterm outcomes like quality of life seem to be equivalent for open and laparoscopic surgery.Multiple studies have proven that the laparoscopic approach to CD and UC is a safe and successful alternative for selected patients. The appropriate selection criteria are still under investigation.Technical considerations are playing an important role for the complexity of both diseases.
文摘Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer. In contrast, laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm. While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach, whether the same oncologic clearance, specifically an adequate TME can be obtained is of concern. The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes. The data from 8 RCTs, 3 metaanalyses, and 2 Cochrane Database of Systematic Reviews was reviewed. Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss, earlier return of bowel function, and shorter hospital length of stay. Concerns that laparoscopic rectal cancer surgery compromises short-term oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature. Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

文摘Objective The present study aims to identify the clinicopathologic factors predictive of lymph node metastasis(LNM) in poorly differentiated early gastric cancer(EGC) and to expand the possibility of using laparoscopic surgery for the treatment of poorly differentiated EGC. Methods Data from 70 cases of poorly differentiated EGC treated with surgery were collected.The association between clinicopathologic factors and the presence of LNM was retrospectively analyzed by univariate and multivariate logistic regression analyses. Results Univariate analysis showed that tumor size,depth of invasion,and lymphatic vessel involvement(LVI) were the significant and independent risk factors for LNM(all P<0.05).The LNM rates were 6.9%,45.5%,and 60.0%,respectively.There was no LNM in 25 patients without the above three risk factors. Conclusions Laparoscopic surgery is a sufficient treatment for intramucosal poorly differentiated EGC if the tumor is less than or equal to 2.0 cm in size and when LVI is absent upon postoperative histological examination.
文摘Objective:The aim of this study was to observe the effect of endobronchial blocker tube in the pulmonary carcinoma with video-assisted thoracic surgery.Methods:Forty patients of pulmonary carcinoma with video-assisted thoracic surgery were randomly assigned into two groups with twenty cases each:endobronchial blocker tube group(group 1) and double-lumen endobronchial tube group(group 2).After anesthesia was induced,in group 1,single lumen tube was intubated at first,and then endobronchial blocker tube intubated to left or right primary bronchus under the guidance of fiber-optic bronchoscope according to operational necessary,injected 2-4 mL air to blocker balloon and blocker one lateral primary bronchus for one-lung ventilation necessarily;while in group 2,the position of double-lumen endobronchial tube was confirmed with fiber-optic bronchoscope after intubation.Blood samples were collected before anesthesia induction,double lumen ventilation,at the one-lung ventilation of 5 min,30 min,60 min,120 min and 180 min,SBP,DBP,HR,SpO2,partial pressure of end tidal carbon dioxide(PetCO2),pH,PaO2,PaCO2,PaO2/FiO2 were recorded.Results:Forty cases' intubations were all successful.There were no differences in SBP,DBP,HR,SpO2,PetCO2,pH,PaCO2 between two groups in different points(P > 0.05).Paw in group 1 was lower than group 2,PaO2 and PaO2/FiO2 in group 1 was higher than group 2 in the one lung ventilation of 5 min,30 min,60 min,120 min and 180 min.Conclusion:The endobronchial blocker tube can meet the request of video-assisted thoracic surgery,with the special advantages of simple insertion,lower airway and better oxygenation.Endobronchial blocker tube offer a new way for one-lung ventilation in the pulmonary carcinoma with video-assisted thoracic surgery.
文摘The "Center of Excellence" concept has been employed in healthcare for several decades. This concept has been adopted in several disciplines; such as bariatric surgery, orthopedic surgery, diabetes and stroke. The most successful model in surgery thus far has been the bariatric program, with a very extensive network and a large prospective database. Recently, the American As-sociation of Gynecologic Laparoscopists has introduced this concept in gynecologic surgery. The "Center Of Excellence in Minimally Invasive Gynecology" (COEMIG) designation program has been introduced with the goals of increasing safety and efficiency, cutting cost and increasing patient awareness and access to mini-mally invasive surgical options for women. The program may harbor challenges as well, such as human and fnancial resources, and diffculties with implementation and maintenance of such designation. This commen-tary describes the COEMIG designation process, along with its potential benefits and possible challenges. Though no studies have been published to date on the value of this concept in the feld of gynecologic surgery, we envision this commentary to provoke such studies to examine the relative value of this new program.
