Endoscopic submucosal dissection (ESD) is widely used in Japan as a minimally invasive treatment for early gastric cancer. The application of ESD has expanded to the esophagus and colorectum. The indication criteria for endoscopic resection (ER) are established for each organ in Japan. Additional treatment, including surgery with lymph node dissection, is recommended when pathological examinations of resected specimens do not meet the criteria. Repeat ER for locally recurrent gastrointestinal tumors may be difficult because of submucosal fibrosis, and surgical resection is required in these cases. However, ESD enables complete resection in 82%-100% of locally recurrent tumors. Transanal endoscopic microsurgery (TEM) is a well-developed surgical procedure for the local excision of rectal tumors. ESD may be superior to TEM alone for superficial rectal tumors. Perforation is a major complication of ESD, and it is traditionally treated using salvage laparotomy. However, immediate endoscopic closure followed by adequate intensive treatment may avoid the need for surgical treatment for perforations that occur during ESD. A second primary tumor in the remnant stomach after gastrectomy or a tumor in the reconstructed organ after esophageal resection has traditionally required surgical treatment because of the technical difficulty of ER. However, ESD enables complete resection in 74%-92% of these lesions. Trials of a combination of ESD and laparoscopic surgery for the resection of gastric submucosal tumors or the performance of sentinel lymph node biopsy after ESD have been reported, but the latter procedure requires a careful evaluation of its clinical feasibility.

Gastroendoscopic treatments, such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), are standard treatments for early gastrointestinal cancer in Japan. Medical endoscopists often perform these procedures in Japan; however, Masanori Hirao, who first reported endoscopic resection (ER) (a forerunner of ESD) using a local injection of hypertonic saline-epinephrine for the treatment of early gastric cancer[1], was a surgeon with experience in the performance of gastrectomies.

ER was developed to reduce the number of excessive surgeries for early gastric cancer without lymph node metastasis (LNM), but the indications for ER have been expanded to other conditions and organs.

Endoscopic treatment was principally developed for the examination of conditions with no LNM[2-5] and to improve the resectability of tumors[6,7]. ESD has expanded as a new and less invasive treatment that enables complete tumor removal without surgery (Figure 1).

ESD has three main advantages over surgery; specifically, it is less invasive, is less expensive, and better preserves physiological function. However, complete resection is impossible in some difficult cases, and the rate of complete resection is not 100% in high-volume institutes. Subsequent surgery may be required for curative treatment in some cases (Figure 2).

ESD may be applied for secondary lesions after some surgeries, such as esophagectomy and gastrectomy. A new technique in this field is joint laparoscopic surgery and ESD, which has been attempted for the treatment of submucosal tumors, including gastrointestinal stromal tumors (GISTs). The ESD technique is used as a novel, less invasive, natural orifice transluminal endoscopic surgery (NOTES).

This article discusses the relationship between ESD and surgical treatment from several viewpoints.


Additional surgery with lymph node dissection is recommended when ER is histologically non-curative. Non-curative ESD is defined as the presence of cancer cells in the lateral or deep margins, invasion to the deep layer, the presence of lymphatic vessel invasion, the presence of an undifferentiated cell type, or a combination of these conditions. The definitions vary according to the affected organ.


Mortality after esophagectomy is 14%[8], which is much higher than that after ESD. Therefore, the decision to perform an esophagectomy for esophageal cancer should be carefully considered. The 2007 guidelines of the Japanese Esophageal Society for the diagnosis and treatment of esophageal squamous cell carcinoma (SCC) state that intraepithelial tumors (M1) and tumors invading the lamina propria (M2) that spread to less than two-thirds of their circumference are absolute indications for esophageal ER, and tumors that are in contact with or invading the muscularis mucosa (M3) without clinical lymph node involvement are a relative indication for ER.

Intensive pathological investigations of a large number of surgical resection cases have demonstrated that less than 5% of M1 and M2 cases exhibit LNM, and the 5-year survival rate is greater than 90%; most deaths result from other causes. However, M3 and submucosa (SM1) cases (i.e., tumors that invade the most superficial third of the submucosa) exhibit a 10%-32% risk of LNM[3,6,9]. Therefore, additional treatment is not necessary for M1 and M2 cases, but additional treatment, such as esophagectomy or chemoradiation, must be considered for M3 and SM1 cases. The indication for additional surgery is controversial in M3 cases. Eguchi et al[9] investigated 464 consecutive patients who had undergone radical esophagectomy with lymphadenectomy and found that 42% of patients with M3 lesions and lymphatic invasion (LY) exhibited LNM, but only 10% of patients with M3 lesions without LY exhibited LNM. The authors concluded that M3 lesions with LY should be treated similarly to SM lesions, and patients with M3 lesions without LY can be followed up without any additional treatment. Shimizu et al[10] found that 16 patients with esophageal carcinoma that invaded the muscularis mucosa or upper submucosa who underwent EMR followed by chemoradiotherapy but refused esophagectomy exhibited no local recurrence or metastasis. The overall survival rate of these 16 patients at 5 years was 100%, but 39 patients with similarly staged cancer who underwent esophagectomy after EMR exhibited a survival rate of 87.5%[10]. A phase II study to evaluate the efficacy and safety of combined EMR and chemoradiotherapy treatment for clinical stage I esophageal cancer (T1b: SM1-3) is ongoing[11]. The necessity of additional surgical treatment and alternative treatments should be considered based on the pathological findings, age, comorbidities, and the patient’s wishes, and the clinical protocol should be strictly followed.


ESD was first applied in the stomach, and most of the clinical and pathological data for this technique can be pooled. The en bloc resection and complete resection rates are 83%-95% and 73%-92%, respectively[12-18], which suggests that complete resection is not obtained in 8%-27% of cases. Additional treatments are required in these cases. The 2004 guidelines for the diagnosis and treatment of stomach carcinoma from the Japanese Gastric Cancer Society[19] recommend ER for the lesion, which meets the following criteria: macroscopic mucosal cancer, less than 2 cm, differentiated type (pap, tub1, tub2), and the absence of ulceration and scarring in the case of the depressed type. Expanded criteria include differentiated mucosal cancer without ulceration irrespective of the tumor size, differentiated mucosal cancer with ulceration if the size is less than 3 cm, and differentiated lesions less than 3 cm in size that invade less than 500 μm into the submucosa and without evidence of lymphovascular invasion on computed tomography or endoscopic ultrasound[4,20].

Patients who undergo treatment according to these expanded criteria exhibit similar long-term survival and outcomes as patients who are treated according to the basic criteria[21]. Patients are considered to have undergone non-curative ER when histological examinations reveal that the resected specimen does not meet the criteria for curative ER (Table 1) according to the Japanese Classification of Gastric Carcinoma[22]. Surgery remains the standard treatment after non-curative ER in patients with a possible risk of LNM[23]. The incidence of residual tumors in surgical specimens of gastric cancer was 24.6% (out of 118 cases) after incomplete ESD, and radical gastrectomy should be performed if pathological examination reveals a positive lateral resection margin after ESD[24]. However, gastrectomy with lymph node dissection should be considered for patients with submucosal invasion regardless of margin status because of possible residual tumor or LNM[25]. A suspicious margin status should be managed similarly to a positive margin status after endoscopic treatment because of the high rate of residual cancer. These authors emphasized that gastrectomy is sometimes unnecessary because recurrence may involve only the mucosa, and more minimally invasive treatment modalities, such as re-ESD and other endoscopic interventions, are recommended in these cases. Incomplete resection by gastric ESD significantly increases the local recurrence risk, and most initial recurrence lesions that are treated with additional argon plasma coagulation recur[26].

or minute submucosal invasive cancer (SM1) less than 30 mm in size

Elderly patients should not undergo radical surgery if they have comorbid diseases or a limited life expectancy. However, additional surgery following non-curative ER improves overall and disease-free survival compared with nonsurgical observation in stomach cancer patients > 75 years of age[27], and surgery should be considered following non-curative ER in elderly patients.

Colon and rectum

The 2010 Guidelines for the Treatment of Colorectal Cancer from the Japanese Society for Cancer of the Colon and Rectum recommends colorectal ER for intramucosal cancer (M) and cancers with slight invasion into the submucosal layer of less than 2 cm in diameter, irrespective of the shape, based on a large number of studies on resected specimens[5,28,29]. The guideline-recommended indications for additional surgical treatment are presented in Table 2. The budding grade and histological type exhibit a greater association with LNM than the depth of submucosal invasion[30,31], and well-differentiated adenocarcinoma without budding may be observed after complete ER even if the cancer invades the submucosal layer.

Repeat EMR as a cure for locally recurrent gastrointestinal tumors is difficult to perform because the initial ER or chemoradiotherapy produces submucosal fibrosis. Surgical resection is necessary in these cases. However, ESD allows for a submucosal dissection through the fibrosis to achieve an en bloc resection.


EMR was evaluated as a salvage treatment after chemoradiotherapy for esophageal cancer prior to the introduction of ESD, but the rate of en bloc resection was not high enough to warrant its use. Saito et al[32] reported that 100% of cases of locally recurrent or residual superficial esophageal SCCs after chemoradiotherapy were successfully resected en bloc using ESD, and these results were superior to the en bloc resection rate of 47% for EMR.


The rates of en bloc resection, complete resection, and curative resection for EMR for locally recurrent gastric cancer are 0%, 41%, and 33%-41%, respectively[17,33]. Surgical resection after EMR should be considered for non-curative cases. The rates of en bloc resection, complete resection, and curative resection for ESD are 89%, 95%, and 76%-80%, respectively, even in locally recurrent cases[17,18,33]. Furthermore, the rate of perforation is 3%-9%[17,33], which is comparable to the 3%-10%[12-16,18,34] perforation rate for ESD in new cases. Conservative treatment was performed after closure with an endoscopic clip in all of the perforation cases[17,33]. ESD is a useful treatment that can prevent the need for surgical resection for locally recurrent gastric cancer.

Colon and rectum

Kuroki et al[35] used ESD in 34 consecutive cases of residual or locally recurrent colorectal tumors. The perforation rate was 14.7% (five cases), emergency surgery was required in one case, and the rates of en bloc resection and complete resection were 93% and 82%, respectively. These authors concluded that the use of ESD for residual/locally recurrent lesions was curative and efficacious, and this technique reduces surgical resection requirements. The en bloc[36] resection rate of ESD in 30 cases of residual or locally recurrent colorectal tumors was 93%, and the complete resection rate was 83%. However, these favorable results were reported at high-volume institutions, and this procedure is not easily performed because of submucosal fibrosis, spastic bowel movements, and the low controllability of the scope in the right colon[37]. The use of ESD for a recurrent lesion requires a highly advanced technique, and the laparoscopic resection of colonic cancer may be performed within almost the same time frame as ESD at some institutions[38]. Therefore, the treatment modality for a residual/recurrent tumor in the colon should be chosen according to the technical abilities of the physician.


Transanal resection (TAR) (Figure 3A) and TEM (Figure 3B) are well-developed surgical procedures for the local excision of rectal adenomas, intramucosal cancers, and superficial submucosal cancers of the rectum. ESD is associated with a longer procedure time than TAR (131 min vs 63 min), but ESD is more effective than TAR for the treatment of non-invasive rectal tumors, with a lower recurrence rate (0% vs 15.5%) and shorter hospital stays (4.9 d vs 7 d)[39]. TEM provides better visualization than TAR, and the clinical results with TEM are superior. However, the recurrence rate is as high as 4%-8%[40-43]. TEM exhibits a technical advantage because it enables the removal of the full thickness of the rectal wall, but the recurrence rates are 0% for SM1, 17% for SM2, and 30% for SM3. Therefore, TEM alone is not a feasible treatment for massive SM rectal cancers, and its indication is not broader than ESD. TEM suffers from poor visualization of the operative field near the dentate line, relatively high recurrence rates, and high instrumentation costs. Therefore, ESD may be a better technique for adenoma, intramucosal cancer, and slightly invasive submucosal cancer in the rectum. Figure 4 presents an example case of ESD for a rectal tumor larger than 10 cm.

Perforation and bleeding are the major complications during the ESD procedure, and perforation, bleeding, and stenosis may occur after the operation. Most of the bleeding may be treated using an endoscopic approach, but all perforations are traditionally treated using salvage laparotomy with closure of the perforation and intensive intra-abdominal lavage with a large volume of physiological saline. However, perforation during the ESD procedure may be nonsurgically treated using endoscopic closure followed by adequate intensive conservative treatment[44].


The perforation rate in esophageal ESD is 0%-20%[6,45-51]. Perforation may cause severe emphysema or mediastinal inflammation, which may require surgical or interventional mediastinal drainage[52]. However, immediate endoscopic closure of the perforation followed by intensive conservative treatment can avoid the need for surgery in most perforations during the ESD procedure[44]. Pneumomediastinum, which does not cause clinically significant complications, is frequently detected after esophageal ESD by chest computed tomography (31%)[53]. Esophageal ESD is associated with esophageal stenosis, particularly when ESD involves the entire circumference of the esophageal lumen. Various techniques, including intralesional steroid injection[54], oral prednisolone administration[55,56], balloon dilatation[55-58], and the placement of a self-expanding metal stent, are used[59,60], and surgical treatment is not generally necessary. However, a small risk of perforation has been observed during balloon dilatation[61] and steroid injection[54]; therefore, these procedures should be performed carefully.


Perforation during ESD for stomach tumors occurs in 2%-10% of cases, and most perforations are treated using endoscopic and conservative treatments without a surgical approach[12-18]. However, delayed perforation after gastric ESD generally requires emergency surgery. Hanaoka et al[62] demonstrated that delayed perforation after gastric ESD occurred in six of 1159 patients (0.45%), and five of these six patients required emergency surgery. Three of these patients were treated using omentoplasty. However, two patients required gastrectomy because the perforation hole was too large to be closed with an omental patch in one patient, and the omentum had been removed in a previous colectomy in the other patient.

Colon and rectum

The perforation rate in colorectal ESD is 4%-10%, and most cases are treated nonsurgically[35,62-69]. However, delayed perforation after colorectal ESD generally requires emergency surgery. Saito et al[64] observed perforations after colorectal ESD in 54 of 1111 cases (4.9%) and delayed perforation in 4 cases (0.4%). Two immediate perforations with ineffective endoscopic clipping and three delayed perforations required emergency surgery. Fujishiro et al[70] reported 11 (5.5%) immediate perforations in 200 cases of colorectal ESD that were successfully managed conservatively, but one delayed perforation (0.5%) required laparotomy.


The remnant stomach after gastrectomy remains at high risk for a second primary gastric cancer. Traditionally, the outcome for patients with gastric cancer in the remnant stomach has been poor, and the standard treatment for remnant gastric cancer was total gastrectomy with extended lymph node dissection[71]. However, Takeda et al[72] observed that none of the 15 patients with early remnant gastric cancer in his consecutive series presented LNM, and the prognosis of these patients was good. The quality of life after total gastrectomy is markedly reduced. Therefore, ER is a highly desirable method for the preservation of the stomach. ER of the lesion in the remnant stomach is technically difficult using the conventional method of EMR because of the narrow inner space and the massive fibrosis around the staples in the suture line. The rates of en bloc resection and complete resection in the ESD of remnant gastric tumors are 97%-100% and 74%-92%, respectively[73-75]. The 0%-13% perforation rate is higher than the perforation rate in the normal stomach, but all perforations have been successfully treated[73-75]. ESD improves the avoidance of surgical resection in early lesions in the remnant stomach after gastrectomy.

ESD is also highly indicated for tumors in the gastric tube after esophagectomy. The en bloc resection rate of ESD for gastric tube tumors is 88%-90%[76,77], which is higher than the rate associated with EMR[76]. One case of successful ESD for a tumor in a colonic interposition after esophagectomy has been reported[78].

A retrospective analysis of 639 cases of esophageal cancer in patients who underwent gastric tube reconstruction and survived more than 10 years revealed that gastric cancer developed at a constant rate, even many years after esophagectomy, with a 10-year cumulative incidence rate of 8.1%[76]. The duration of survival has improved due to progress in the diagnosis and treatment of esophageal cancer. A lesion in a reconstructed organ, such as a gastric tube or colonic interposition, will likely appear more often, and ESD will play a more important role in the treatment of these lesions.

Sentinel lymph node biopsy after ESD

ESD is applied to benign or early malignant lesions without LNM, and the indication criteria for its use in each organ are discussed above. Local excision may be permitted if no LNM is specifically proven in cases that do not meet the criteria, such as intramucosal undifferentiated carcinoma or massively invaded submucosal cancer. The use of laparoscopic sentinel lymph node biopsy (SLNB) for the examination of LNM after ESD for early gastric cancer that does not meet the standard or expanded indication criteria has been reported[79]. Additional curative surgical resection was performed when LNM was observed. Cahill et al[80] applied NOTES after ESD of the stomach and sigmoid colon in a porcine model based on the same criteria. However, a systemic review of 21 articles on SLNB in gastric cancer patients revealed that the overall sensitivity of SLNB was 85.4%[81]. The authors concluded that there was insufficient evidence to introduce SLNB into the treatment protocol for gastric cancer[81]. A meta-analysis of 53 studies on SLNB in colon and rectal cancer revealed a pooled sensitivity of only 76%[82]. The accuracy of SLNB varies according to the biopsy procedure, experience, and method of staining. Therefore, technical improvements in SLNB may lead to the clinical application of the combination therapy of ESD and SLNB using laparoscopic surgery or NOTES.

Gastric submucosal tumors

The combination of ESD and laparoscopic surgery as a novel treatment method for gastric submucosal tumors, such as GISTs, has been reported at some institutions. Laparoscopic excision has been applied to gastric submucosal tumors, but the precise location of the lesion could not be detected in the laparoscopic view. Therefore, excessive resection is inevitable for complete resection. The ESD technique is used for mucosal cutting and full-thickness wall cutting around the lesion prior to laparoscopy to minimize excessive resection. Complete resection is then performed using a laparoscopic approach[79,83-86] (Figure 5).

Application of the ESD technique to NOTES

NOTES has attracted considerable attention as a mini-mally invasive surgery. Endoscopic transesophageal mediastinal lymph node dissection and epicardial coagulation using mediastinal and thoracic approaches in a porcine model have been reported previously[87] (Figure 6). An element of the ESD technique has been applied to these novel surgeries.

Additional treatments, including surgery with lymph node dissection, should be recommended to patients with non-curative resection following ESD. ESD may be successfully applied for a residual/recurrent gastrointestinal tumor after ER, a second primary tumor in the remnant stomach after gastrectomy, or a tumor in the gastric tube or colon that was reconstructed after gastroenterological surgery. ESD is superior to TAR and TEM for the treatment of an early rectal tumor. Most of the perforations that occur during the ESD procedure can be treated nonsurgically using endoscopic closure, but delayed perforations require emergency surgery. This review summarized novel trials of the combination of ESD and laparoscopic surgery, and the application of an element of the ESD technique to NOTES was reported.
