完全腹腔镜远端胃癌D2根治术

近年来,随着腹腔镜手术技术和器械的发展,完全腹腔镜远端胃癌根治术在国内逐渐开展,主要难点问题仍集中于消化道重建。完全腹腔镜远端胃癌根治术的消化道重建方式主要有B-Ⅰ式三角吻合,B-Ⅱ式吻合和Roux-en-Y吻合等。B-Ⅰ式三角吻合法操作简便,但较适合于早期胃癌患者;B-Ⅱ式操作简单,但易出现碱性反流性胃炎;Roux-en-Y吻合能有效避免反流,但术后停滞综合征发生率较高,且全腹腔镜下操作繁琐。笔者2013年9月在国内率先开展全腔镜下胃空肠Uncut Roux-en-Y吻合,该方式既保证了肠道的连续性,降低了停滞综合征的发生率,又有效阻断了胆胰液反流至胃肠吻合口,且全腔镜下实施简便、并发症少,安全有效,值得推荐。

Early international results of laparoscopic gastrectomies

Background: The first totally laparoscopic Billroth II gastrectomy was performed in 1992. To date, laparoscopic gastrectomy has been performed by a small number of surgeons around the world and the laparoscopic approach has been extended to Billroth I and total gastrectomy. The aim of this study is to review the state of laparoscopically performed gastrectomies in the international scene. Methods: Questionnaires were prepared and sent to every surgeon in the world known by the authors or their contacts to have performed a laparoscopic gastrectomy. A questionnaire survey was started in July 1994 and completed by November 1994. Data collected included age, sex, type of gastric resection, technique of reconstruction after resection, average duration of surgery, time to liquid and solid intake, postoperative hospital stay, complications, and opinions of the surgeons. Results: Sixteen surgeons contributed to this study. A total number of 118 cases of laparoscopic gastrectomies, comprising Billroth I (11), Billroth II (87), vagotomy and antrectomy (10), and total gastrectomy (10) had been performed. The indications were gastric and/or duodenal ulcers and benign and malignant gastric tumors. Conclusions: Laparoscopic gastrectomy was found to be superior to the open technique by 10 of 16 surgeons because of faster recovery, less pain, and better cosmesis. The procedure was an expensive and long operation according to four. Two surgeons were uncertain of any benefit because of limited experience. Received: 7 August 1996/Accepted: 28 October 1996     

Laparoscopic distal gastrectomy with regional lymph node dissection for gastric cancer

Background Recent advances in surgical techniques have led to widespread acceptance of laparoscopic gastrectomy for gastric cancer. We performed distal gastrectomy with regional lymph node dissection in 235 patients with gastric cancer located in the middle and lower third of the stomach. Methods In 171 cases, reconstruction was done using the Billroth I method intracorporeally and the aid of laparoscopic linear stapling devices. The Billroth II and Roux-en-Y methods were used in the remaining 56 and eight patients, respectively, Results Patients who underwent laparoscopic distal gastrectomy had a more rapid postoperative recovery than those treated via the open approach. Postoperative complications with this technique were within a permissible range. In terms of the survival curve, there was no statistical difference between the laparoscopic group diagonesed as clinical T2N0 (c T2N0) Preoperatively and the open group. Conclusion The laparoscopic technique is not only less invasive, but is also similarly safe and curative compared to open gastrectomy.     

Intracorporeal Billroth 1 reconstruction by triangulating stapling technique after laparoscopic distal gastrectomy for gastric cancer

As the laparoscopic operations for gastric cancer have increased, the intracorporeal reconstruction of the digestive tract has received attention because the procedure offers a good visual field regardless of the patient's figure. We performed laparoscopic gastrectomies with regional lymph node dissection on 586 gastric cancer patients between March 1998 and June 2006: 465 distal gastrectomies, 42 proximal gastrectomies, and 79 total gastrectomies. Intracorporeal anastomosis was carried out in 303, 36, and 69 of the above cases, respectively. The intracorporeal Billroth 1 reconstruction was performed in 226 out of the 303 cases who underwent distal gastrectomy and intracorporeal anastomosis. The "triangulating stapling technique" (TST) that uses laparoscopic linear stapling devices was adopted for 196 of these 226 cases; in the remaining 30, circular stapling devices for conventional open gastrectomy (CEEA) were used. In the initial 115 cases of distal gastrectomy, hand-assisted laparoscopic surgery (HALS) was used, and then we shifted to totally laparoscopic distal gastrectomy (TLDG) without HALS. In this paper, we concentrated on the techniques and results of intracorporeal Billroth 1 reconstruction by TST. Reducing postoperative wounds was possible TLDG by TST, compared with HALS and the extracorporeal anastomosis, that is, laparoscopy-assisted distal gastrectomy. Complications from anastomosis resulted in leakage in 2 HALS-TST patients and in 1 TLDG-TST patient, and anastomotic stenosis and bleeding were observed in each 1 case of reconstruction that used CEEA. Intracorporeal Billroth 1 reconstruction by TST is a safe procedure that provides a good visual field regardless of the patient's figure and a feasible technique for reconstruction after laparoscopic distal gastrectomies.

Laparoscopic distal gastrectomy with regional lymph node dissection for gastric cancer

Recently, a minimally invasive operation for gastric malignancies has been advocated, and the laparoscopic operation is noted as a technique that increases the quality of life. We performed distal gastrectomy with regional lymph node dissection on 160 cases of gastric cancer located in the middle or lower third of the stomach. In 123 cases, Billroth I reconstruction was performed intracorporeally using the quadrilateral (square) stapling technique with a laparoscopic linear stapling device to prevent postoperative anastomotic bleeding and stenosis. In the remaining 37 cases, the Billroth II method was performed with a linear stapling device [1]. This technique is not only less invasive but also as safe as open gastrectomy, which was performed on 100 gastric cancer cases of similar staging.     

Early detection of gastric remnant carcinoma. The role of gastroscopic screening

Partial gastrectomy for benign ulcer disease has been associated with carcinoma in the gastric remnant. To detect formation of this cancer in patients having undergone this operation, we initiated a screening protocol using barium contrast studies, flexible gastroscopy, and biopsy. Patients were selected from a group of 233 patients who had undergone partial gastrectomy for benign disease between 1960 and 1975. In this group, operations for duodenal ulcer had been performed in 156 patients (83 Billroth I and 73 Billroth II reconstructions) and subtotal gastrectomy in 77 patients with gastric ulcer (17 Billroth I and 60 Billroth II reconstructions). From July 1980 to July 1985, 163 patients underwent gastroscopy and biopsy with a median postoperative interval of 14.6 years. Through screening, three resectable remnant carcinomas were found. We conclude that routine gastroscopy leads to earlier detection and a higher rate of resectability if gastric remnant carcinoma is found; yearly screening should be performed after a ten-year postresection interval; and gastroscopic biopsy is more accurate than upper gastrointestinal tract barium contrast studies and should be used preferentially to identify gastric remnant carcinoma.     

Reconstructive procedure after distal gastrectomy for gastric cancer that best prevents duodenogastroesophageal reflux

Billroth I and II reconstructions are commonly performed after distal gastrectomy. Both may cause duodenogastric and duodenogastroesophageal reflux, conditions reported to have carcinogenetic potential. The aim of this study was to investigate which reconstructive procedure would most effectively prevent bile reflux into the gastric remnant and esophagus after distal gastrectomy. A group of 92 patients who underwent curative distal gastrectomy for gastric cancer were subjected and classified into three groups retrospectively by the reconstructive procedure undertaken: group A, Roux-en-Y (Roux-Y) reconstruction (n = 29); group B, Billroth I reconstruction (n = 41); group C, Billroth II reconstruction (n = 22). The bile reflux periods (percent time) for the gastric remnant and esophagus were measured with the Bilitec 2000 under standardized conditions. The percent time for the gastric remnant was significantly less in group A than in group B or C. In 61% of all patients, bile reflux into the esophagus was found to be more than 5.0% of the time; it was less in group A than in group B or C (p = 0.057). A questionnaire revealed a good correlation between the incidence of reflux symptoms and the percent time for the gastric remnant and esophagus. Roux-Y reconstruction is superior to either Billroth I or II reconstruction for preventing bile reflux into the gastric remnant and esophagus after distal gastrectomy.

The advantages and disadvantages of a Roux-en-Y reconstruction after a distal gastrectomy for gastric cancer

In Japan, the Billroth I and Billroth II operations have been used for reconstruction after a distal gastrectomy for gastric cancer. However, a Roux-en-Y reconstruction is increasingly performed to prevent duodenogastric reflux. We herein discuss the indications for Roux-en-Y in gastric surgery and review the literature to determine its advantages and disadvantages. Indications for Roux-en-Y reconstruction after a distal gastrectomy are: (a) When the primary lesion has directly invaded the duodenum or head of the pancreas, the Billroth I operation is likely to result in local recurrence near the anastomosis; (b) in addition, the Billroth I operation is not indicated after a subtotal gastrectomy due to an unacceptable anastomotic tension; reconstruction using a nonphysiological route is therefore preferred. The advantages of Roux-en-Y reconstruction after a distal gastrectomy include a reduction of reflux gastritis and esophagitis, a decreased probability of gastric cancer recurrence, and a reduction in the incidence of surgical complications such as ruptured suture lines. The disadvantages of Roux-en-Y reconstruction include the possible development of stomal ulcer, an increased probability of cholelithiasis, increased difficulty with an endoscopic approach to the ampulla of Vater, and the possibility of Roux stasis syndrome. The principal advantage of a Roux-en-Y reconstruction is that it is less likely than the Billroth I operation to result in duodenogastric reflux. Roux-en-Y reconstruction or Billroth I operation can only be selected after considering their respective advantages and disadvantages.     

Laparoscopy-assisted distal gastrectomy for gastric malignant lymphoma

Although the best treatment for gastric malignant lymphoma remains a controversial matter, surgery is the first choice for localized malignant lymphoma without lymph node metastasis and invasion to the adjacent organ. We report a case of gastric malignant lymphoma that was managed with laparoscopy-assisted distal gastrectomy. A 47-year-old man was referred to our department for management of gastric lymphoma. After preoperative examination revealed a tumor confined to the gastric wall but no lymph node metastasis, we performed laparoscopy-assisted Billroth I gastrectomy. Histopathologic examination confirmed that the tumor was follicular center lymphoma limited to the submucosa with no lymph node metastasis. The postoperative course was good. This is the first reported case of laparoscopic gastrectomy-treated gastric malignant lymphoma. Because it involves minimal access and invasiveness, this procedure may be an effective method of treatment of localized malignant lymphoma of the stomach.

Totally laparoscopic gastrectomy with various types of intracorporeal anastomosis using laparoscopic linear staplers: preliminary experience

Background We analyzed our preliminary clinical data for totally laparoscopic gastrectomy (TLG) in order to evaluate its effectiveness in terms of minimal invasiveness, technical feasibility, and safety. Methods Forty-five consecutive patients who underwent TLG in our institution between June 2004 and February 2006 were enrolled in this study. There were 26 men and 19 women, with a mean age of 58.8 years and a mean body mass index (BMI) of 23.2. In all cases, only laparoscopic linear staplers were used for intracorporeal anastomosis. Results The reasons that gastrectomy was performed were adenocarcinoma in 41 cases, benign disease in three cases and gastrointestinal stromal tumor in one case, and the types of surgery were distal gastrectomy (40), total gastrectomy (four) and pylorus-preserving gastrectomy (one). Among the distal gastrectomies, Billroth I (25) was the most frequent procedure, followed by uncut Roux-en-Y gastrojejunostomy (14) and Billroth II (one), respectively. The mean operation time was 314 minutes, the mean anastomotic time was 41 minutes, the mean number of staples used was eight, and the mean estimated blood loss was 150 ml. There was no case of conversion to an open procedure. The first flatus was observed at 2.9 days, and liquid diet was started at 3.7 days. The mean number of postoperative analgesic use, except for patient-controlled analgesia (PCA), was 1.4 times, and the mean postoperative hospital stay was 11 days. Postoperative complication occurred in six patients (13.3 %), but no postoperative mortality occurred. There were two cases of delayed gastric empting and one case of anastomotic leakage, anastomotic stenosis, intraabdominal bleeding, and ventral hernia each. All of the patients recovered well with conservative or surgical management. Conclusions TLG with intracorporeal anastomosis using laparoscopic linear staplers was safe and feasible, and we were able to obtain acceptable surgical outcomes in terms of minimal invasiveness.     

Minimally invasive surgery for gastric cancer

BACKGROUND: The use of laparoscopic surgery in the treatment of gastric cancer has not yet met with widespread acceptance; thus, it should be regarded as still in the developmental phase. Nevertheless, the laparoscopic approach appears to have some valuable advantages for the management of gastric cancer patients, and it can be expected to have a dramatic impact on public health expenditures. Herein we present the results of our experience with laparoscopic and laparoscopy-assisted gastrectomies for cancer, and we discuss the role of these procedures in current surgical practice. METHODS: Between June 1993 and November 1997, we performed a total of 13 laparoscopic procedures on 13 patients affected with gastric carcinoma. There were eight male and five female patients with a mean age of 65.4 years (range, 42-78). All patients were staged preoperatively with US and CT scan and required to sign a formal consent. RESULTS: Altogether we performed nine D1 laparoscopic total gastrectomies, seven of which were done with a laparoscopy-assisted approach; three D2 laparoscopy-assisted total gastrectomies, associated in one case with a distal pancreasectomy; and one laparoscopy-assisted distal gastrectomy performed on a morbid obese patient. The preliminary laparoscopic staging allowed for a better definition of tumor extension and identification of undetected hepatic metastases in two patients. The mean duration of the intervention was 240 min. Blood losses were as high as 300 cc on average. We recorded one major intraoperative complication, consisting of an inadvertent injury to the proper hepatic artery, which was successfully repaired by the same laparoscopic route. The postoperative course was uneventful in all patients but one, who died of acute hepatic failure on day 6. At a mean follow-up of 27.5 months, 11 patients are still alive. Two of them have hepatic metastases and nine are disease-free. CONCLUSIONS: Although they remain challenging procedures, laparoscopic gastrectomies appear to be oncologically adequate. We believe that a pure laparoscopic approach should be reserved for low-stage lesions (N0, up to T2), while a combined approach is preferable for locally advanced cancer (N1 or higher, T3 or higher). Much work still needs to be done to establish the optimal strategy in both open and laparoscopic surgery, but laparoscopy can be a valuable tool in the decision-making process for patients affected with gastric malignancies.     

Cholelithiasis after gastric surgery--possibilities and limits of laparoscopic approach

An increased incidence of cholelithiasis has been widely reported after gastric surgery. In the early phase of patient selection, previous gastric surgery has been considered a relative contraindication to laparoscopic cholecystectomy. Between 1999-2003, in our clinic, laparoscopic cholecystectomy was attempted on 3145 patients. Of these patients, 37 patients had gallstone, which occurred several years (mean 17.9 years) after gastric surgery for peptic ulcer (34 cases), gastric cancer (1 case) and hiatal hernia (2 cases). Surgical procedures that had been performed included Billroth I gastrectomy (14 cases), Billroth II gastrectomy (15 cases), truncal vagotomy and piloroplasty (6 cases), and Nissen (2 cases). On this group there were 19 chronic cholecystites, 17 acute cholecystites and one cholesterolosis with gallbladder polyps. One patient was diagnosed with gallstone in common bile duct, successfully removed preoperatively after endoscopic sphincterotomy. The laparoscopic approach was possible in 26 cases. The technical difficulty after Cuschieri was level III--26 patients and level IV--11 patients (reconversion). The mean operative time was 75 minutes. The postoperative evolution of the patients was good in 36 cases. One case had a biliary fistula. The mean postoperative hospital stay was 3.6 days for laparoscopic cholecystectomy and 9 days after conversion. The postoperative adhesions determine the main technical difficulty, but it proved to be a relative contraindication for laparoscopic cholecystectomy for gallstones after gastric surgery. Clear visualization of anatomic structures and landmarks, and scrupulous hemostasis are needed to perform a safe laparoscopic cholecystectomy in these patients.     

Safety and application of laparoscopic gastrectomy for benign gastric disease and gastric cancer

INTRODUCTION

Laparoscopic gastrectomy is rapidly expanding despite reservations by some surgeons regarding its safety and radicality. The aim of this study was to evaluate patients undergoing laparoscopic gastrectomy for both benign and malignant disease with particular emphasis on technical feasibility, safety, effectiveness and complications.

PATIENTS AND METHODS

Review of prospectively collected data of patients who underwent laparoscopic gastrectomy from May 2005 to September 2009 under the care of one consultant surgeon.

RESULTS

A total of 61 laparoscopic gastrectomies were performed (35 men and 26 women) with a median age of 68 years (range, 41–90 years). There were 39 distal gastrectomies (19 adenocarcinoma, 6 gastrointestinal stromal tumour [GIST], 4 benign gastric outlet obstruction, 4 high-grade dysplasia in gastric adenomas, 4 non-healing ulcers, 2 gastric antral vascular ectasia [GAVE]); 15 sub-total gastrectomies (13 adenocarcinomas, 2 GIST); and 7 total gastrectomies (5 adenocarcinomas, 1 GIST, 1 carcinoid). Median follow-up was for 48 months (range, 1–72 months). There was one death, two major and six minor complications. All patients with complications made a satisfactory recovery.

CONCLUSIONS

Laparoscopic gastrectomy is associated with a low mortality (1.75%) and major morbidity (3.50%). Although technically demanding, especially when a D2 lymphadenectomy is performed, our results have shown that tailored laparoscopic resection based on tumour characteristics with either D1 or D2 lymphadenectomy results in good surgical and oncological outcomes.     

Laparoscopic gastric resections

The impressive breakthrough in laparoscopic surgery has pushed surgeons to perform gastric resection through such an approach. Laparoscopy reduces the surgical stress and the postoperative pain and has a positive impact on the rehabilitation time, the hospital stay, and return to work and social activities. Laparoscopic partial gastrectomy for benign diseases and for palliation has been accepted as an effective surgical option: they are reproducible operations performed worldwide at a more and more rapid pace. Laparoscopic gastric resections and laparoscopically assisted gastric resections for malignancy deserve a word of caution. Nevertheless, the investigators report their series of laparoscopic subtotal and distal gastrectomies for cancer with medium and long-term results comparable with those of open surgery. Furthermore, new and less invasive surgical options have been recently introduced. Full and partial thickness local resections may be accomplished through intragastric procedures, for treatment of small benign tumors and early stage gastric cancer.     

Laparoscopically assisted total or distal gastrectomy with lymph node dissection for early gastric cancer

BACKGROUND: A secure lymphadenectomy in a laparoscopically assisted gastrectomy performed for gastric cancer is required because of the high prevalence of lymph node metastasis. A surgical technique for laparoscopic gastrectomy with lymph node dissection and reconstruction using a conventional circular stapler is reported. METHODS: Forty-nine laparoscopically assisted gastrectomies with lymphadenectomy (47 distal and two total gastrectomies) were performed using devices for retraction of the stomach and laparoscopic ligation of arteries, which were developed to ensure secure dissection of lymph nodes. Reconstruction by Billroth I or intestinal interposition using a conventional circular stapler was performed through a small incision through which the specimen was removed. When submucosal invasion was suspected (n = 16), the lymph nodes along with the common hepatic artery were also dissected through the same incision. RESULTS: The operations were performed without serious complication. None was converted to laparotomy, and there were no deaths. Metastatic lymph nodes were seen in perigastric nodes and nodes along the left gastric artery in five cases. In five of the 49 patients the macroscopic diagnosis of depth of invasion was underestimated. CONCLUSION: A technique of laparoscopic gastrectomy with lymph node dissection for early invasive gastric cancer is described. A definitive answer concerning the appropriate level of lymph node dissection and the role of laparoscopic gastrectomy in the treatment of more advanced gastric cancer remains to be defined.
