Abstract
Gastroparesis (GP) can be a severe and debilitating disease. Its pathophysiology is complex and not completely understood. Two principal mechanisms are responsible for the development of symptoms - gastric hypomotility and pylorospasm. Pylorus targeted therapies aim to decrease presumably elevated pyloric tone - pylorospasm. There is a growing body of evidence about their role in the treatment algorithm of GP. G-POEM (endoscopic pyloromyotomy) is an extensively studied pylorus targeted therapy. Its efficacy ranges between 56 and 80% and the number of recurrences among those with treatment effect seems low. G-POEM is a safe procedure with very low frequency of severe adverse events. At present, G-POEM should not be considered as an experimental approach and may be offered to all patients with refractory and severe GP. Nevertheless, G-POEM is not a first line treatment. Conservative measures such as diet modification and pharmacotherapy should always be tried before G-POEM is considered. Further research must focus on better patient selection as at present there are no standardized criteria. Functional imaging such as impedance planimetry (EndoFlip) may hold promise in this regard.

Abstract
BACKGROUND The pylorus plays a key role in the control of gastric content outflow. Impairment of pyloric physiology has been observed in gastroparesis, particularly when associated with diabetes mellitus or opioid intake or after antireflux surgery. New tools have been developed to identify pyloric dysfunction in routine care, including functional luminal impedance planimetry (FLIP). As such, a new therapeutic strategy targeting the pylorus, namely endoscopic pyloromyotomy (G-POEM), has received increasing attention and emerged as a promising treatment for gastroparesis. PURPOSE The present review details the involvement of the pyloric pathophysiology in gastroparesis, as well as clinical results of G-POEM according to the current literature.

Feasibility and safety of inserting transient biodegradable stents in the pylorus during pylorus-preserving gastrectomy for gastric cancer: a preliminary study in a porcine for proof of concept. Gastric Cancer 2023; 26:155-166. [PMID: 36417001 DOI: 10.1007/s10120-022-01350-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 11/02/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND To evaluate whether insertion of self-biodegradable stent into the pylorus to prevent delayed-gastric emptying after pylorus-preserving gastrectomy is feasible and safe through porcine experiment. METHODS Self-biodegradable dumbbell-shaped pyloric stents were designed from absorbable suture materials: poly(glycolide-co-caprolactone) (PGCL) or poly-p-dioxanone (PPDO). After gastrotomy on ten pigs, each stent was inserted: two shams, four PGCL stents, and four PPDO stents. Body weight (Bwt), body temperature (BT), complete blood cell (CBC) count, and plain X-ray were evaluated. On postoperative day (POD) 13, euthanasia was performed for histologic evaluation. RESULTS Operation was successfully performed in all ten pigs. Without tagging suture, both stents migrated before POD 3. The migration was delayed up to POD 13, when the tagging sutures (-t) were applied between stent and stomach wall. Self-degradation of PGCL started from POD 3, and stents were completely excreted from the abdomen by POD 8. Although PPDO were also weakened as self-degradation progressed, its shape was maintained in gastrointestinal tract for 13 days. Unexpected sudden death occurred in the pig with PPDO-t2 on POD 10, which is more likely due to acute volvulus rather than stent-related complication. There was no significant difference between three groups in terms of Bwt, BT, CBC, and histology (sham vs. PGCL vs. PPDO, all p > 0.05). CONCLUSION The concept of biodegradable stents made of absorbent suture material seems feasible in porcine experiment. Among them, PGCL which has shown rapid absorption, appears to be a more suitable material for transient pyloric absorbable stent when considering safety aspect.

Abstract
Background Pyloric botulinum toxin injection has improved symptoms in children with delayed gastric emptying. We aimed to determine the clinical response to combined endoscopic intra-pyloric botulinum toxin injection and pyloric balloon dilation (IPBT-BD) in patients with dyspepsia. Methods Electronic medical records were reviewed to gather demographic data, symptoms, and follow-up on patients with dyspepsia. Cases were defined as those who underwent IPBT-BD in addition to their ongoing management. Controls received pharmacotherapy, behavioral intervention, or dietary management alone. Clinical response was defined as no change, partial, or complete improvement in symptoms within 12 months. Propensity score matching based on age, gender, and symptom duration was used to pair cases and controls. Results In total, 79 cases and 83 controls were identified. After propensity matching, 63 patients were included in each group. The mean age for cases was 14.5 ± 3.9y; 62% were females and 98% were Caucasian. Further, 83% of 46 cases and 94% of 49 controls who had scintigraphy scans showed delayed gastric emptying. After matching, 76% of cases showed partial or complete improvement compared with 49% controls within 12 months (P = 0.004). Younger children tended to respond more favorably to the procedure (P = 0.08). Conclusions In our propensity-matched analysis, combined IPBT-BD in addition to pharmacotherapy, behavioral, or dietary management clearly showed a benefit over these modalities alone. This favorable response lasted up to 12 months.

Abstract
Purpose This study aimed to compare the surgical and oncological outcomes between totally laparoscopic pylorus-preserving gastrectomy (TLPPG) with intracorporeal anastomosis and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with extracorporeal anastomosis. Materials and Methods A retrospective analysis was performed in 258 patients with cT1N0 gastric cancer who underwent laparoscopic pylorus-preserving gastrectomy using two different anastomosis methods: TLPPG with intracorporeal anastomosis (n=88) and LAPPG with extracorporeal anastomosis (n=170). The following variables were compared between the two groups to assess the postoperative surgical and oncological outcomes: proximal and distal margins, number of resected lymph nodes (LNs) in total and in LN station 6, operation time, postoperative hospital stay, and postoperative morbidity including delayed gastric emptying (DGE). Results The average length of the proximal margin was similar between the TLPPG and LAPPG groups (2.35 vs. 2.73 cm, P=0.070). Although the distal margin was significantly shorter in the TLPPG group than in the LAPPG group (3.15 vs. 4.08 cm, P=0.001), no proximal or distal resection margin-positive cases were reported in either group. The average number of resected LN was similar in both groups (36.0 vs. 33.98, P=0.229; LN station 6, 5.72 vs. 5.33, P=0.399). The operation time was shorter in the TLPPG group than in the LAPPG (200.17 vs. 220.80 minutes, P=0.001). No significant differences were observed between the two groups in terms of postoperative hospital stay (9.38 vs. 10.10 days, P=0.426) and surgical complication rate (19.3% vs. 22.9%), including DGE (8.0% vs. 11.8%, P=0.343). Conclusions The oncological safety and postoperative complications of TLPPG with intracorporeal anastomosis are similar to those of LAPPG with extracorporeal anastomosis.

Radiologic intervention due to delayed gastric emptying after pylorus preserving gastrectomy for gastric cancer does not affect pyloric function. KOREAN JOURNAL OF CLINICAL ONCOLOGY 2020; 16:89-95. [PMID: 36945716 PMCID: PMC9942724 DOI: 10.14216/kjco.20014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 11/08/2020] [Accepted: 11/18/2020] [Indexed: 11/07/2022]
Abstract
Purpose The purpose of this study is to evaluate whether radiologic intervention in the pylorus decreases its function for delayed gastric emptying (DGE) patients after pylorus preserving gastrectomy (PPG) for gastric cancers and to determine the optimal interventional algorithm. Methods PPG patients who underwent intervention for DGE from January 2013 to December 2017 and a control group using propensity score matching were identified. Pyloric function was compared by subjective symptoms, postoperative upper gastrointestinal series at 3 months (short-term function), and esophagogastroduodenoscopy findings at 12 months (long-term function). Serum albumin levels and body weight change, 6 months and 12 months postoperatively, were compared to evaluate nutritional status. Interventional success rate, mean hospital stay, and recurrence of DGE were analyzed to determine the optimal intervention plan. Results Fifty-one out of 677 patients (7.53%) received intervention. There was no difference in pyloric function and nutritional status between the intervention and control groups. The interventional success rate for first-time balloon dilatation was 41.7% (20/48). If a second intervention was required and balloon dilatation was done, the success rate was 45.5% (5/11). However, if stent insertion was done, the success rate was 100% (17/17). Subsequent stent insertion after balloon dilatation resulted in a shorter mean hospital stay. Intervention including stent insertion had a lower recurrence of DGE than balloon only intervention (1.96% vs. 5.88%, P=0.041). Conclusion Radiologic intervention did not decrease long-term pyloric function. For treating DGE, if at first balloon dilatation fails, retrievable stent insertion can be considered as a second choice.

Abstract
Surgical resection remains the primary choice of treatment and the only potentially curative option for gastric carcinoma, and is increasingly performed laparoscopically. Gastric resection represents a challenging procedure, with a significant morbidity and non-negligible postoperative mortality. The interpretation of imaging after gastric surgery can be challenging due to significant modifications of the normal anatomy. After the surgery, the familiarity with expected imaging appearances is crucial for diagnosis and appropriate management of potentially life-threatening complications in patients who underwent gastric surgery. We review various surgical techniques used in gastric surgery and describe fluoroscopic and cross-sectional imaging appearances of normal postoperative anatomic changes as well as early and late complications after gastric surgery.

Abstract
This paper reports a case of a twisted small bowel obstruction in a 74-year-old man that occurred after a double tract reconstruction (DTR) in a laparoscopic proximal gastrectomy (PG) for early gastric cancer. The patient had inadequate oral intake and reflux symptoms for 10 days after discharge. Imaging analysis revealed a narrowed small bowel with twists between the esophagojejunostomy and gastrojejunostomy sites. A fully covered stent was placed in the narrowed small bowel for 2 weeks. The patient was then discharged after stent removal without any dietary problems. The authors' experience shows that twisted small bowel after a DTR in PG can be treated by endoscopy.

Abstract
BACKGROUND Pylorus-preserving gastrectomy (PPG) is commonly performed for early gastric cancer (EGC) located in middle third of the stomach. We investigated the surgical, oncological, and functional outcomes of PPG involving the upper third of stomach. METHODS We included all patients of the period 2013-2016 who underwent PPG, distal subtotal gastrectomy (DSG), and total gastrectomy (TG) for EGC involving the upper third by carefully defining the localization. Surgical, oncological, and functional outcome analyses included postoperative morbidity, lymph-node metastasis, tumor recurrence, postoperative body weight, body mass index, hemoglobin, total protein, albumin, quantification of intraabdominal fat, and gallstone development. RESULTS Overall, 288 cases were analyzed: 145 PPG, 61 DSG, and 82 TG. In the study period, patients potentially underwent PPG for EGC involving the upper third, if enough proximal remnant stomach was found whilst achieving a sufficient proximal margin. PPG resulted in less operation time (p < 0.001), less blood loss (p = 0.002) and lower postoperative morbidity compared to TG. For lymph-node (LN) stations being resected in all groups, no difference was found in number of resected LN. Recurrence-free survival was similar for all groups. PPG showed advantages regarding postoperative body weight, hemoglobin, total protein, albumin in postoperative 6 and 12 month follow-up. Lowest decrease of abdominal fat area after 12 months was seen for PPG. Gallstone incidence was significantly lower after PPG compared to TG (p < 0.001). CONCLUSIONS For EGC involving the upper third, PPG can be another good option with lower postoperative morbidity, better functional outcomes, and same oncological safety.

Abstract
Background Laparoscopic-assisted pylorus-preserving gastrectomy (LAPPG) is a minimally invasive function-preserving surgery for early gastric cancer. This study was designed to investigate the clinical outcomes between LAPPG and laparoscopy-assisted distal gastrectomy (LADG) by objective evaluation. Methods A total 167 pT1N0M0 gastric cancer patients underwent LAPPG(n = 70) and LADG(n = 97) were retrospectively analyzed. By evaluating the functional advantages, objective short-term and one year follow-up outcomes were compared. Results There is no significant difference in perioperative clinical characteristics as well as pathologic results between LAPPG and LADG group while the cost is higher in latter(p = 0.004). The Clavien–Dindo grade II or higher complications were 15.7 and 13.4% in LAPPG and LADG group respectively(p = 0.824). In one year follow-up, nutritional status was significantly better in LAPPG group accompanied by better pylorus function preserving. Conclusion LAPPG is an acceptable surgical procedure for pT1N0M0 middle portion gastric cancer patients in terms of nutritional and economic advantage.

Abstract
BACKGROUND Gastroparesis is a syndrome characterized by delayed gastric emptying with associated symptoms. It was reported that the symptoms of diabetic gastroparesis had been greatly improved by transpyloric stent placement. However, the use of stents in benign conditions is considered to be contraindicated because of the increasing risk of complications, such as stent migration, reflux, perforation, bleeding, and, most importantly, new strictures caused by stent-induced tissue hyperplasia. While temporary placement of a self-expanding metallic stent (SEMC) can drastically reduce the risk of complications, few reports are available on the treatment of refractory PSG by temporary transpyloric stent. Does it have a long-term clinical effect after the stent being retrieved? CASE PRESENTATION After accepting partial resection of the lesser curvature in another hospital, a patient developed refractory gastroparesis. The symptoms hadn't been improved after long-term drug therapy and balloon dilation therapy. Four months after surgery, a fully covered SEMC was placed by endoscopy in our hospital. Gastroparesis had been greatly improved. Two weeks later, the transpyloric stent was retrieved and the patient didn't show recurrent symptoms. Follow-ups were arranged at 3 months, 6 months and 1 year respectively, and there was no evidence of recurrence was found. CONCLUSIONS This case indicates that temporary transpyloric SEMC is a safe, effective and less invasive alternative for post-surgical gastroparesis patients.

Abstract
BACKGROUND Delayed gastric emptying is one of the most disturbing complications of pylorus-preserving gastrectomy (PPG) and it increases hospital stay. We investigated the clinical outcome of intraoperative manual dilatation of the pylorus as a preventive method of pyloric spasm after PPG. MATERIALS AND METHODS We reviewed gastric cancer patients who underwent PPG between January 2014 and December 2016 at Seoul National University Hospital by a single surgeon. During operation, manual dilatation (MD) was performed after laparoscopic dissection and gastric resection by mini-laparotomy. Pyloric stenosis was diagnosed by the finding of severe narrowing in pylorus on upper gastrointestinal series (UGIS), if patients suffered from postprandial abdominal fullness and discomfort. Patient's characteristics, surgical data and complication data were reviewed and compared between the groups (MD vs non-MD). RESULTS 232 patients were included in this study. 93 patients underwent manual dilatation (40.1%). The overall complication rate was 12.9% in the MD group and 18.7% in the non-MD group (p = 0.242). Mean postoperative stay was 10.0 ± 5.8 in the MD group versus 10.9 ± 8.4 in the non-MD group (p = 0.304). Only one case suffered pylorus stenosis in the MD group (1.1%) but there were twelve cases seen in the non-MD group (8.6%), which reflects a significant difference (p = 0.019). CONCLUSION Simple intraoperative manual dilatation of pylorus may provide prevention from pyloric stenosis caused by pyloric spasms for patients who undergo PPG.

Abstract
Purpose To report our experience of endoscopic botulinum toxin injection in patients who experienced severe delayed gastric emptying after pylorus-preserving gastrectomy (PPG). Materials and Methods We reviewed the medical records of 6 patients who received the botulinum toxin injection. They presented with severe delayed gastric emptying in the early postoperative period. Endoscopic botulinum toxin was administered as 4 injections of 25−50 IU into each of the 4 quadrants of the prepyloric area. Results All botulinum toxin injections were successful without any complications, enabling 5 patients to tolerate soft solid diets and one to tolerate a soft fluid diet within 10 days. The endoscopic criteria of 4 patients improved. Symptom recurrence caused 2 patients to undergo repeat injections that were successful. The median follow-up period was 27 months, and all patients could ingest normal regular diets at the last follow-up. Conclusions Endoscopic botulinum toxin injection is a feasible treatment option for early delayed gastric emptying after PPG.

Abstract
Objective To determine the efficacy of retrievable metallic stent with fixation string for benign anastomotic stricture after upper gastrointestinal (UGI) surgery. Materials and Methods From June 2009 to May 2015, a total of 56 retrievable metallic stents with fixation string were placed under fluoroscopy guidance in 42 patients who were diagnosed with benign anastomotic stricture after UGI surgery. Clinical success was defined as achieving normal regular diet (NRD). Results The clinical success rate after the first stent placement was 57.1% (24/42). After repeated stent placement and/or balloon dilation, the clinical success rate was increased to 83.3% (35/42). Six (14.3%) patients required surgical revision to achieve NRD. One (2.4%) patient failed to achieve NRD. Stent migration occurred in 60.7% (34/56) of patients. Successful rate of removing the stent using fixation string and angiocatheter was 94.6% (53/56). Distal migration occurred in 12 stents. Of the 12 stents, 10 (83.3%) were successfully removed whereas 2 could not be removed. No complication occurred regarding distal migration. Conclusion Using retrievable metallic stent with a fixation string is a feasible option for managing early benign anastomotic stricture after UGI surgery. It can reduce complications caused by distal migration of the stent.

Abstract
Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.
