Clinicopathologic and endoscopic characteristics of ten patients with gastric hamartomatous inverted polyp: a single center case series

BACKGROUND

Gastric hamartomatous inverted polyps (GHIPs) are not well characterized and remain diagnostically challenging due to rarity. Therefore, this study aims to investigate the clinicopathologic and endoscopic characteristics of patients with GHIP.

METHODS

We retrospectively reviewed clinicopathologic and endoscopic features of ten patients with GHIP who were admitted to Beijing Friendship Hospital from March 2013 to July 2022. All patients were treated successfully by endoscopic resection.

RESULTS

GHIPs were usually asymptomatic and found incidentally during gastroscopic examination. They may be sessile or pedunculated, with diffuse or local surface redness or erosion. On endoscopic ultrasonography, the sessile submucosal tumor-type GHIP demonstrated a heterogeneous lesion with cystic areas in the third layer of the gastric wall. Histologically, GHIPs were characterized by a submucosal inverted proliferation of cystically dilated hyperplastic gastric glands accompanied by a branching proliferation of smooth muscle bundles. Inflammatory cells infiltration was observed in the stroma, whereas only one patient was complicated with glandular low-grade dysplasia. Assessment of the surrounding mucosa demonstrated that six patients (60%) had atrophic gastritis or Helicobacter pylori-associated gastritis, and four patients (40%) had non-specific gastritis. Endoscopic resection was safe and effective.

CONCLUSIONS

GHIPs often arise from the background of abnormal mucosa, such as atrophic or H.pylori-associated gastritis. We make the hypothesis that acquired inflammation might lead to the development of GHIPs. We recommend to make a full assessment of the background mucosa and H. pylori infection status for evaluation of underlying gastric mucosal abnormalities, which may be the preneoplastic condition of the stomach.

Follow-up study of three cases of congenital microgastria

Current knowledge on congenital microgastria is limited due to its extreme rarity, and the paucity of nutritional and quality of life follow-ups. Patients affected by congenital microgastria cases followed at out center were screened, and general and nutritional status were evaluated at follow-up visits through validated questionnaires. Three cases were included: one patient died because of a complex syndromic picture where microgastria was imperatively approached conservatively. The remaining cases underwent Hunt-Lawrence at 2 and 17 months. After 2 years and 27 years postoperatively, both patients are on full oral intake. The 28-yearold patient did not reach a BMI higher than 18. She rated her quality of life as unimpacted, with a Gastrointestinal Quality of Life Index of 111. In the other case, parents reported about their 2-yearold child an Infant Gastrointestinal Symptom Questionnaire of 13, corresponding to "no distress". Our findings confirm the literature trend supporting the role of early surgery in microgastria to improve outcomes. We presented the nutritional status and quality of life in two cases of congenital microgastria operated according to Hunt-Lawrence at a 2-year and 27-year distance, which is the longest follow-up reported to date.

Gastric bronchogenic cyst

A 47-year-old man presented with a 6-day pain in the right chest. Abdominal CT showed an elliptical homogeneous mass, which was closely related to the posterior wall of the stomach and the lesion grew from the posterior wall of the stomach to the abdominal cavity in the wedge shape. The enhanced scan showed no enhancement in the lesion. The left adrenal gland and the upper pole, pancreas and spleen were changed due to compression. Carbohydrate antigen 72-4 (CA72-4) was 45.1U/ml (0.00～5.30 U/ml). The gastroscopy results showed that there was protruded lesion in the posterior gastric wall and atrophic gastritis in the superficial stomach. Laparoscopic exploration and partial gastrectomy were performed. An 8cm × 7cm tumor was found at the posterior wall of the fundus near the cardia, with smooth serosal surface. The cystic mass was smooth surface, filled with yellow thick liquid. Microscopically, the cystic wall tissue was lined with pseudo-stratified ciliated columnar epithelium, and mucous glands were seen under the epithelium. Pathological diagnosis showed bronchogenic cysts of the gastric submucosal. At 2-month follow-up, the postoperative recovery was good.

Subtotal pyloric obstruction by atypical hypertrophic pyloric muscle in a newborn

This is a case of a neonate with suspected duodenal atresia on prenatal imaging. However, distal bowel gas was identified postnatally on regular X-rays with a possible pyloric obstructing mass visualised on ultasound. No contrast was visualised passing through the stomach on fluoroscopic studies. Operative evaluation revealed an atypical asymmetric hypertrophic pylorus with exophytic lesions of ectopic glandular tissue. Longitudinal open pyloromyotomy was performed which relieved the gastric obstruction resulting in symptomatic relief without any anatomy altering procedure required.

Surgical Management of Intra-gastric Balloon Complications, Single-Center Experience, and Literature Review

INTRODUCTION

In Saudi Arabia, the prevalence of obesity has multiplied in the last decades leading to a surge in bariatric surgery and other endoscopic modalities. The intra-gastric balloon (IGB) is the most used endoscopic modality. Surgical management for IGB complications is required for gastrointestinal perforation and/or obstruction. However, the literature seems to underestimate these complications.

MATERIALS AND METHODS

A retrospective descriptive study was conducted in King Fahd University Hospital, Saudi Arabia, from Jan 2017 to Dec 2021, including all patients with complicated IGB who necessitated any surgical procedure. Exclusion criteria were patients with complicated IGBs that were only managed conservatively or endoscopically.

RESULTS

A total of 326 patients were admitted with different complications after bariatric procedures. Of them, six patients were referred due to IGB complications that necessitated operative intervention. All patients were young females. Three patients had gastric wall perforation, and were managed by endoscopic removal of the IGBs followed by exploratory laparotomy. One patient had an intestinal obstruction on top of a migrated IGB that was surgically removed. One patient had failed endoscopic retrieval of IGB and required a laparoscopic gastrostomy. Another patient had an esophageal rupture that required left thoracotomy, pleural flap, and insertion of an esophageal stent. All cases were discharged and followed up with no related complications.

CONCLUSION

IGB is an endoscopic alternative, within specific indications, for the management of obesity. However, surgical management may be necessary to manage its complications, including gastrointestinal perforation, IGB migration, and failure of endoscopic removal.

One-step laparoscopy-guided abomasopexy versus omentopexy via right flank laparotomy to treat left displaced abomasum in dairy cows, in relation to return of milk yield

This study compared two surgical techniques for treating left displaced abomasum (LDA) in dairy cows. The two techniques were compared in terms of milk production at different time intervals: before surgery; on the day of the surgery; and at 8, 15 and 30 days after surgery. The surgical techniques used in this study were laparoscopy-guided abomasopexy and right flank laparotomy omentopexy. A total of 126 lactating Holstein-Friesian cows with LDA were included, 63 of which were treated with laparoscopy, and 63 with right flank laparotomy. Cows with retained foetal membranes, metritis or natural delivery (dystocia) were included and registered on field sheets for subsequent statistical analysis. Cows with clinical mastitis were excluded. A blood sample (5 mL) was obtained from the medial coccygeal vein and analyzed for total proteins, total bilirubin, total calcium, glucose, b-hydroxybutyrate, sodium, potassium, and chloride. No differences were found between the two groups of operated cows with respect to the number of lactation days, body condition score (BCS), rectal temperature, heart rate, and respiratory rate before surgery. No differences were observed between groups regarding the biochemical parameters (P > 0.05) analyzed, except for chloride, which presented lower average values in the omentopexy group (P <0.05). Return of milk yield within the study period did not differ significantly between the laparoscopy and laparotomy groups (P > 0.05), although a significant change in post-surgery time was observed. .

Aberrant pancreas adenocarcinoma in the stomach: A case report and literature review

RATIONALE

Aberrant pancreatic tissue in the gastrointestinal tract is a relatively common finding. However, malignant transformation is extremely rare. Herein, we report a case of ectopic pancreatic ductal adenocarcinoma in the stomach wall.

PATIENT CONCERNS

A 38 year old male presented with nausea, bloating, abdominal distention and weight loss for 4 months.

DIAGNOSES

Endoscopy of upper gastrointestinal tract was performed twice with 2 months interval and a stenotic pyloric part was observed with a suspected submucosal lesion. It was sampled both times, however the pathology findings of the mucosal biopsies were unremarkable with no identifiable neoplastic structures. CT scan and MRI was performed and showed a thickened pyloric wall with a submucosal lesion 15 × 15 mm in diameter. Blood levels of tumor markers carcinoembrionic antigen and carbohydrate antigen 19-9 were within a normal range.

INTERVENTIONS

Pyloric stenosis progressed and the patient underwent a Billroth type I distal gastric resection with D2 lymphadenectomy. Pathologic examination revealed a well differentiated ductal adenocarcinoma arising in the heterotopic pancreatic tissue (Heinrich type III). The resection margins and lymph nodes were free of tumor. The patient received adjuvant chemotherapy with 6 courses of XELOX.

OUTCOMES

No disease recurrence is reported in 12 months follow-up.

LESSONS

Aberrant pancreatic ductal adenocarcinoma in the stomach is a rare finding, however this pathology should be included in the differential diagnosis of gastric submucosal lesion causing pyloric stenosis.

Conservative treatment of gastric perforation after microwave ablation of a hepatocellular carcinoma: Case report

RATIONALE

Microwave ablation (MWA) has been proven to be an efficient and safe method for local tumor control of liver tumors. Reported complications are rare, but include liver abscess, hematoma, pleural effusion, and occasional thermal injury of the adjacent colon. Intestinal perforation usually requires immediate surgical treatment to prevent generalized peritonitis and sepsis.

PATIENT CONCERNS AND DIAGNOSIS

Herein, we describe a case of gastric perforation following percutaneous MWA for hepatocellular carcinoma as a bridging therapy prior to liver transplantation.

INTERVENTIONS

Due to the clinical condition of the patient, conservative treatment was considered sufficient. Nine months after MWA, successful liver transplantation followed. Intraoperative findings revealed a scar in the gastric wall with tight adhesions to the liver, requiring adhesiolysis and subsequent suturing. Postoperative recovery was uneventful.

OUTCOME

At present, the patient is doing well. No further gastrointestinal events occurred.

LESSON

To our knowledge, this is the first report of such a complication occurring after MWA. Moreover, in this case, the gastric perforation could be treated conservatively.

Menetrier’s disease exacerbating ulcerative colitis and relieved by gastrectomy

Ménétrier’s disease (MD) is a rare gastropathy characterised by giant rugal folds which can present with nausea, vomiting, abdominal pain and protein losing gastropathy. We report a 21-year-old woman with comorbid MD and ulcerative colitis (UC). Management was complicated by limited treatment options for MD, significant symptom burden, worsening nutrition and difficulty determining which disease was the predominant cause of symptoms. Since age 18 the patient experienced recurrent UC flares characterised by diarrhoea, persistent vomiting and corticosteroid dependence. Endoscopic assessment demonstrated concurrent MD and active UC. Octreotide and cetuximab were trialled given persistent hypoalbuminaemia and suspicion for MD associated protein-losing gastropathy. UC management comprised dose-optimised infliximab and methotrexate. Repeat endoscopic assessment demonstrated improvement in UC without corresponding improvement in symptoms or hypoalbuminaemia. Nasojejunal feeding and parenteral nutrition failed to significantly improve nutritional status and accordingly the patient proceeded to radical total gastrectomy. Postoperatively, MD-associated symptoms and hypoalbuminemia resolved completely.

Intragastric Single-Port Surgery: An Innovative and Multipurpose Technique for the Therapy of Upper Digestive Tract Lesions

Background: Endoscopic treatment can represent a technical challenge for several special situations, such as resecting gastric tumors with larger size or in unfavorable sites and performing endoscopic retrograde cholangiopancreatography (ERCP) after Roux-en-Y gastric bypass (RYGB). This study aims to describe an innovative and multipurpose technique, intragastric single-port surgery (IGS), which can be applied for abovementioned special situations and for assessing its safety, feasibility, and efficacy. Methods: IGS technique was performed through a 2-3 cm skin incision, where the stomach wall is exteriorized and fixed to the skin. The single-port device is inserted and intragastric access is gained for laparoscopic or endoscopic instruments. Three purposes of IGS were performed: (1). gastric intraluminal lesions resection; (2). to perform ERCP after RYGB; and (3). revision of pancreaticogastric anastomosis after pylorus-preserving pancreaticoduodenectomy. Results: IGS was performed successfully in 20 patients. Ten patients underwent gastric intraluminal lesion resection, mostly for gastric gastrointestinal stromal tumors (n = 7, 70%); all pathological specimens were with negative margin, mean operation time was 102.3 ± 43.5 minutes, and mean postoperative hospital stay was 4.6 ± 1.5 days. Nine patients underwent ERCP after RYGB, cleaning of the bile duct was successful in all patients (100%), and mean operation time and mean postoperative hospital stay were 140.6 ± 46.3 minutes and 4.4 ± 2.6 days, respectively. One patient underwent pancreaticogastric anastomosis revision. There were no mortalities in our series. Conclusions: IGS is a safe, feasible, and effective technique for gastric intraluminal lesion resection and for performing ERCP after RYGB, while it has the potential for other future applications.

Effectiveness and safety of reduced-port laparoscopic surgery vs conventional multi-port laparoscopic surgery in the treatment of gastric diseases: A meta-analysis

This study aimed to compare the effectiveness and safety of reduced-port laparoscopic surgery (RPLS) and conventional multi-port laparoscopic (CMPLS) surgery in the treatment of gastric diseases.The PubMed, Embase, Cochrane Library, Web of Science, and Chinese Biomedical Literature databases were systematically searched for randomized controlled trials, cohort studies, and case control studies on the use of RPLS vs conventional multi-port laparoscopic surgery in treating gastric diseases from their inception until March 10, 2019. The evaluated outcomes were the operative time, blood loss, length of hospital stay, number of dissected lymph nodes, postoperative complications, and conversions. All of these were compared using Stata software version 12.0.A total of 18 studies were included, which involved 2938 patients. In studies referring to the comparison between RPLS and CMPLS in treating gastric diseases, the former showed significantly inferior in terms of operative time (P = .011) and number of dissected lymph nodes (P = .031); but superior results in terms of the estimated blood loss (P = .000) and length of hospital stay (P = .001) than the latter did; however, the rates of postoperative complications (P = .830) and conversions (P = .102) were not statistically significant between the 2 groups.RPLS and CMPLS showed comparable effectiveness and safety in the treatment of gastric diseases in our meta-analysis. Based on the current evidence, we believe that RPLS is an efficacious surgical alternative to CMPLS in the management of gastric diseases because of the shorter hospital stay and reduced blood loss. However, large-scale, well-designed, multicenter studies are needed to further confirm the results of this study.

Post-Gastrectomy Complications - An Overview

Post-gastrectomy complications have been the associated sequelae after curative gastrectomy for long time. They include a conundrum of symptoms ranging from serious metabolic alterations to disorders attributed to mechanical and neural factors after reconstruction of the digestive continuity. Though, with the advancement in the surgical expertise and techniques and shift towards medical and endoscopic management for benign gastro-duodenal ulcer disease, there has been a decline in the incidence of these complications; they continue to raise "red flags" after major oncologic gastric resections. Identification of these symptoms and protocol based management of the same is of utmost importance in the surgical armamentarium of trainees and practicing physicians and surgeons.

Endoscopic gastric body plication for the treatment of obesity: technical success and safety of a novel technique (with video)

BACKGROUND AND AIMS

Primary obesity surgery endoluminal (POSE) is a primary endoscopic bariatric therapy focusing on gastric remodeling. The original POSE procedure involved placement of full-thickness plications in the fundus. Here we aim to assess the feasibility, safety, and efficacy of a novel POSE procedure that involves plications of only the gastric body to reduce the width and length of the stomach.

METHODS

This was a pilot study of patients who underwent a distal POSE procedure with gastric body plications for the treatment of obesity. Outcomes included technical success rate, serious adverse event (AE) rate, and efficacy of this novel POSE procedure at inducing weight loss and improving obesity-related comorbidities.

RESULTS

Ten patients (6 women, age 52 ± 20 years) underwent a distal POSE procedure. Baseline body mass index was 38.1 ± 6.2 kg/m². The technical success rate was 100%. An average of 21 ± 4 plications were placed per case (6 ± 2 for distal belt, 10 ± 3 for suspenders, 4 ± 2 for proximal belt, and 3 ± 1 for fillers). The gastroesophageal junction was pulled distally by 3.0 ± 1.6 cm. The gastric body was shortened by 11.0 ± 5.1 cm, representing a 59% reduction. The serious AE rate was 0%. At 6 months, patients experienced 15.0% ± 7.1% total weight loss (TWL). All patients achieved at least 5% TWL, and 8 patients (80%) achieved at least 25% excess weight loss. Hypertension, diabetes, GERD, and obstructive sleep apnea improved after the procedure.

CONCLUSIONS

This novel POSE procedure, focusing on gastric body plication and sparing the fundus, is technically feasible and appears to be safe and effective for the treatment of obesity.

[A Case Report of Bypass Surgery for a Perforated and Unresectable Gastric Cancer]

A 74-year-old man was admitted to a clinic because of epigastralgia in June 2018. He was referred to our hospital for further examination of right hydronephrosis. He was diagnosed as having type 2 gastric cancer in the middle gastric body and lesser curvature, with an upper gastric fiber, swollen para-aortic lymph node, and right hydronephrosis by using abdominal computed tomography. PET-CT revealed no hot spot in the para-aortic lymph node but revealed a hot spot in the lower small bowel. He was admitted to our hospital because of severe abdominal pain and appetite loss and underwent a reduction and palliative surgery for the unresectable gastric cancer. The omental cavity was perforated and penetrated into the retroperitoneum. He underwent esophageal jejunal bypass and intestinal fistula tube insertion in the stomach. He had a central vein port and was discharged from our hospital. He was able to eat during his short overnight stay at our hospital after the operation but died on postoperative day 30.

A case report of infant with gastric perforation caused by Candida albicans infection

RATIONALE

Spontaneous gastric perforation in young children is rare, and gastric perforation caused by Candida albicans infection is even rarer.

PATIENT CONCERNS

A 4-month-old infant presented with frequent retching. The results of X-rays showed obvious pneumoperitoneum but gastric vacuole was not seen.

DIAGNOSIS

The infant was diagnosed as spontaneous gastric perforation caused by C albicans infection based on blood culture, peritoneal fluid culture, and postoperative histopathology.

INTERVENTIONS

An emergency exploratory laparotomy was performed and a gastric perforation repair was done. The infant received antishock, antiinfection, and intravenous nutrition treatment.

OUTCOMES

After operation and antiinfective symptomatic treatment, the infant recovered.

LESSONS

This case emphasized the rare C albicans infection as a cause of the gastric perforation in infant. The C albicans infection should always be thought of as an etiology for the gastric perforation in infant, to reduce the significant mortality. The early detection is necessary to treat Candida infections.

Bile reflux gastritis cystica profunda: A case report and literature review

RATIONALE

Gastritis cystica profunda (GCP) is a rare gastric lesion involving cystic dilation of the gastric glands extending into the submucosa. It is usually observed at anastomotic sites in the stomach of patients who have undergone gastric procedures. Bile reflux GCP is rare in patients who have not undergone gastric surgery. Here, we report a rare case of a patient with GCP associated with bile reflux, who had no history of gastric surgery.

PATIENT CONCERNS

A 50-year-old man presented with intermittent abdominal fullness for 2 years, along with nausea. He had never undergone gastric surgery. Endoscopic ultrasonography (EUS) showed a thickened gastric wall and an echo-poor submucosal layer of the gastric fundus. A 3 cm × 2 cm × 1.5 cm lesion was noted.

DIAGNOSIS

Bile reflux GCP INTERVENTIONS:: Endoscopic retrograde cholangiopancreatography and endoscopic submucosal dissection (ESD) were performed, and the lesion was removed. Conventional pathological examination revealed GCP with glands hyperplasia and a yellow-brown deposit, which was considered bile. The findings were consistent with a diagnosis of GCP without malignancy.

OUTCOMES

Upper gastrointestinal barium meal revealed postoperative changes at the gastric fundus. Gastroscopy performed at 6 months after surgical resection showed superficial gastritis with bile reflux.

LESSONS

The findings suggest that GCP etiology varies and that GCP can be caused by bile reflux but without malignancy. Additionally, GCP is not limited to patients who have previously undergone gastric surgery. Moreover, it is difficult to identify. EUS and ESD might be good approaches for the diagnosis and treatment of GCP.

Removal of an infant's gastric duplication cyst through endoscopic submucosal dissection: A case report

RATIONALE

Gastric duplication cyst is an anomaly that primarily occurs to children. Apart from the conventional use of surgical resection, few cases using endoscopic treatment have been reported.

PATIENT CONCERNS

A 5-month-old female infant was hospitalized with the chief complaint of gastric cyst. No significant abnormalities were identified by physical examination.

INTERVENTIONS

Endoscopic submucosal dissection (ESD) was performed successfully for the infant and the duration was less than 20 minutes. The patient showed no postoperative complications.

OUTCOMES

At 4 months during the follow-up, upper endoscopy revealed a small scar at the previous site of the lesion and no recurrence.

LESSONS

According to the results of PUBMED review, she was the youngest with gastric duplication cyst removed with ESD. The less invasive ESD should be considered an effective therapeutic option to remove gastric duplication cyst in children.

[Establishment and clinical application of modified endoscopic freka trelumina placement]

OBJECTIVE

To establish a modified endoscopic Freka Trelumina placement (mEFTP) for modifying or substituting the traditional endoscopic Freka Trelumina placement (EFTP) and to explore the safety and feasibility of mEFTP in patients requiring enteral nutrition and gastrointestinal decompression in general surgery.

METHODS

A retrospective cohort study was conducted to analyze the clinical data of patients undergoing EFTP or mEFTP at General Surgery Department of 920 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2016 to January 2018.

INCLUSION CRITERIA

the function of lower digestive tract was normal; patients who could not eat through mouth or nasogastric tube needed to have enteral nutrition and gastrointestinal decompression; the retention time of Freka Trelumina (FT) was not expected to exceed 2 months.

EXCLUSION CRITERIA

contraindication for gastroscopy; suspected shock or digestive tract perforation; suspected mental diseases; infectious diseases of digestive tract; thoracoabdominal aortic aneurysm. mEFIP procedure was as follow. FT was inserted into stomach through one side nasal cavity, gastroscope was inserted into stomach cavity, and the front part of FT was clamped with biopsy forceps through biopsy hole. Biopsy forceps and FT were inserted into the pylorus or anastomosis under gastroscope, and they were pushed into the duodenum or output loop. During pushing, the gastroscope did not pass through the duodenum or output loop. The biopsy forceps was released and pushed out, and FT was pushed with biopsy forceps synchronously into the duodenum or output loop more than 5 cm. The foreign body forceps was inserted through the biopsy hole, and the FT tube was held in the stomach and pushed to the duodenum or output loop. The previous steps repeated until the suction cavity reached the pylorus or anastomosis. The gastroscope was exited gently; the guide wire was pulled out slowly. EFTP procedure: foreign body forceps was used to clamp the front part of FT, and gastroscope, foreign body forceps and FT pass the pylorus or anastomosis simultaneously to reach the descendent duodenum or output loop as a whole. The time of catheterization was recorded and position of FT was examined by X-ray within 1 h after catheterization. The success rate of catheterization and morbidity of complications after catheterization were evaluated and compared between the two groups.

RESULTS

A total of 141 patients were enrolled, 72 in the mEFTP group and 69 in the EFTP group. In mEFTP group, 45 cases were males and 27 were females with an average age of 55.8(37-76) years; 27 cases had normal upper gastrointestinal anatomy (postoperative gastroplegia syndrome due to colon cancer in 17 cases, due to rectal cancer in 10 cases) and 45 had upper gastrointestinal anatomic changes (gastric cancer with pylorus obstruction in 18 cases and anastomotic block after gastroenterostomy in 27 cases). In the EFTP group, 41 were males and 28 were females with an average age of 55.3(36-79) years; 33 cases had normal upper gastrointestinal anatomy (postoperative gastroplegia syndrome due to colon cancer in 20 cases, due to rectal cancer in 13 cases) and 36 had upper gastrointestinal anatomic changes (gastric cancer with pylorus obstruction in 15 cases and anastomotic block after gastroenterostomy in 21 cases). In patients with normal upper digestive tract anatomy, the average catheterization time of mEFTP was (4.9±1.7) minutes which was shorter than (7.6±1.7) minutes of EFTP(t=6.683, P<0.001). In patients of gastric cancer with pyloric obstruction, the average catheterization time of mEFTP was (6.6±1.6) minutes which was shorter than (10.5±2.6) minutes of EFTP (t=4.724, P<0.001). In patients with anastomotic block after gastroenterostomy, the average catheterization time of mEFTP was (11.3±2.5) minutes which was shorter than (15.1±3.5) minutes of EFTP (t=4.513, P<0.001). In patients with normal upper gastrointestinal anatomy, there were no significant differences in the success rate of catheterization and the morbidity of catheterization complication between mEFTP and EFTP (all P>0.05). In patients with upper gastrointestinal anatomic changes, the success rate of catheterization in mEFTP was even higher than that in EFTP, but the difference was not significant [97.8%(41/45) vs. 86.1%(31/36), χ²=2.880, P=0.089]; while the morbidity of catheterization complication in mEFTP was lower than that in EFTP [0 vs. 8.3%(3/36), χ²=3.894, P=0.048].

CONCLUSIONS

Whether the upper gastrointestinal anatomy is normal or not, mEFTP presents shorter catheterization time, higher success catheterization rate than EFTP, and is safety. mEFTP can be widely applied to clinical practice for patients requiring enteral nutrition and gastrointestinal decompression.

Special Use of Intraoperative Endoscopy in Sleeve Gastrectomy: A Case Report

Sleeve gastrectomy is the most frequently performed operation for the treatment of morbid obesity. Even though sleeve gastrectomy is now widely standardized, it may still benefit from the use of certain devices and procedures such as intraoperative endoscopy. The use of an endoscope offers numerous advantages that can considerably reduce the morbidity and mortality of patients who undergo laparoscopic sleeve gastrectomy. This paper describes our experience with a case in which the information obtained by endoscopy allowed us to perform a real-time assessment of the location of two large gastric polyps to control the staple-line.

Gastroduodenal Surgery: A Persistent and Continuing Challenge

The number of patients being treated surgically for gastroduodenal disease has decreased over the past five decades as a result of focus on medical treatment. However, perforated and bleeding peptic ulcer disease (PUD) continues to represent a significant percentage of patients who require emergency surgery. The aim of this study was to characterize these critically ill surgical patients treated for gastroduodenal disease in our hospital. A retrospective, single-center, consecutive cohort study of all patients identified from the hospital National Surgical Quality Improvement Program database who were admitted to our institution requiring emergent surgical intervention over the past two years was conducted. Of 423 patients, 33 (7.8%) had operative procedures for complications of PUD, of which 19 patients (57.6%) had perforation; nine patients (27.3%) had hemorrhage; one patient (3.0%) had both perforation and hemorrhage; two patients (6.1%) had distal gastrectomies for ulcers refractory to medical management alone, and two patients (6.1%) had gastrectomies for malignant gastric neoplasms. There is a significant population of patients who present with life-threatening complications of PUD, despite the decline in PUD worldwide. These patients are critically ill and require careful and diligent management for good outcomes.

Neonatal gastric perforation: a report of two cases and a systematic review

RATIONALE

Neonatal gastric perforation is a rare and life-threatening disorder in neonates and is associated with high morbidity and mortality. However, the exact mechanisms of neonatal gastric perforation remain unknown.

PATIENT CONCERNS

In this study, we reported 2 cases of neonatal gastric perforation and conducted a systematic review to analyze the prognostic factors for mortality.

DIAGNOSES

Two neonates received a diagnosis of gastric perforation based on clinical presentation and imaging studies. The 2 patients underwent emergent surgery, which yielded favorable outcomes.

INTERVENTIONS

We reviewed 168 cases from the literature as well as our 2 cases to analyze whether mortality in neonatal gastric perforation is associated with sex, gestational age, operation type, perforation location, or timing of perforation.

OUTCOMES

The results revealed that mortality was significantly higher in preterm neonates (n = 80, P < .01) and the mortality group had a lower birth weight (n = 73, P < .05). The timing of perforation in the preterm subgroup was significantly earlier than that in the full-term subgroup (n = 90, P < .05). The outcomes about mortality of gastric perforation were significantly associated with preterm neonates (adjusted odds ratio: 4.21, 95% confidence interval: 1.28-13.88, P < .05).

LESSONS

This study shows the prognostic factor of gastric perforation was significantly associated with preterm neonates. Furthermore, low-birth-weight full-term neonates had a relatively higher mortality rate than the normal-birth-weight full-term neonates. In addition, preterm neonates have an earlier timing of perforation.

Vimentin-positive gastric adenocarcinoma arising in a hyperplastic polyp

We report a case of vimentin-positive early gastric adenocarcinoma arising in a hyperplastic polyp (HP). A 72-year-old Japanese man was admitted for the detailed examination of a gastric polyp. He had a subtotal gastrectomy due to acute abdomen 12 years ago. Upper endoscopy revealed a pedunculated polyp measuring approximately 2 cm on the greater curvature of upper body of the remnant stomach. Magnifying endoscopy revealed that the microsurface pattern was irregular and partially absent accompanied with irregular microvessels at the upper end of the polyp. We speculated that the lesion was an adenocarcinoma arising in the HP. Endoscopic submucosal dissection (ESD) was performed. Histological examination of the ESD specimen revealed that the lesion consisted of well- to poorly differentiated adenocarcinoma at the protruding lesion and foveolar hyperplastic epithelia at the base of the polyp. Immunohistochemically, most of tumor cells that comprised poorly-differentiated adenocarcinoma were positive for both cytokeratin and vimentin. Although carcinomas have occasionally been found in HPs, the histological features of the present case are considered extremely unusual. To the best of our knowledge, this is the first case of vimentin-positive early gastric carcinoma arising in a HP.

[A Case of Gastric Cancer Underwent Two-Stage Gastrectomy after Chemotherapy-Induced Perforation]

A 70's man presenting with a chief complaint of stomachache was found to have advanced gastric cancer with a deep ulcer and some lymph-node metastases. We decided performing a curative operation after 2 courses of S-1 plus cisplatin. On the first course day 13 of chemotherapy, he complained of severe epigastralgia, and we diagnosed as generalized peritonitis due to perforation of gastric cancer. We performed an urgent laparoscopic operation, which made perforation simple closure and omentopexy. Curative distal gastrectomy with D2 lymph node dissection was successfully performed on postoperative day 16.

[Clinicopathological Study of Perforated Gastric Cancer Treated with Surgery]

This retrospective study evaluated an appropriate surgical treatment in patients with perforated gastric cancer. The clinicopathological and survival data on 17 perforated gastric cancer patients treated with surgery were analyzed. The one-stage or two-stage gastrectomy was performed in 8 and 5 patients, respectively. The omental patch repair was performed in 4 patients. In univariate analysis, non-curative(R2)resection with gross residual tumor(p<0.01)and postoperative complications( p=0.01)were found to be significant unfavorable factors for overall survival(OS). In multivariate analysis, R2 resection was identified to be an only independent significant unfavorable factor for OS. Patients who underwent curative(R0) resection had long-term survival, while patients with R2 resection and postoperative complication had limited survival times. These results suggest that R0 resection may be optimal to improve survival in patients with perforated gastric cancer, regardless of whether patients underwent a one-stage or two-stage gastrectomy based on the patient's condition.

[An Analysis of Perforated Gastric Cancer with Acute Peritonitis in Our Hospital]

Perforated gastric cancer is relatively rare and the incidence is reported about 1% of all the cases of gastric cancer. We retrospectively analyzed the clinical data of the consecutive 12 patients with perforated gastric cancer who underwent operation in our hospital between January 2005 and December 2016. There were 5 men and 7 women, with an average age of 65.8 years old(34-87). Perforated gastric cancer occurred in the region U(1 cases), M(6 cases), L(5 cases). There were 11 cases with distant metastasis. We could successfully diagnosed as perforated gastric cancer in 8 cases before emergency operation. Gastrectomy was performed in 5 cases. However, the curative resection was performed only 1 case. Prognosis of perforated gastric cancer is poor. We considered as an appropriate two-step surgical strategy that the first step of surgery is an acute peritonitis treatment followed by radical gastrectomy with lymphadenectomy.

Rate of adverse events of gastroduodenal snare polypectomy for non-flat polyp is low: A prospective and multicenter study

AIM

To evaluate the rate of adverse events (AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers.

METHODS

Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after the procedure.

RESULTS

308 patients were included and a single polypectomy was performed in 205. Only 36 (11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm (5-60) and in 294 cases (95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219 (71.1%) patients. Nine patients presented AEs (2.9%), and 6 of them were bleeding (n = 6, 1.9%) (in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of bleeding.

CONCLUSION

Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location.

[Clinical Evaluation of Perforated Gastric Cancer Cases]

Perforated gastric cancer is relatively rare disease. Between 2006 and 2016, we treated 8 cases with perforative gastric cancer. These cases accounted for 15%of the 53 cases with the upper gastrointestinal tract perforated cases. The median age of perforated gastric cancer case was 66(37-80)years, which was significantly higher than that of perforated benign upper gastrointestinal ulcer(55, 12-97 years)(p=0.033). These patients were divided into 2 groups; 3 cases who died up to 3 months as poor prognosis group and 5 cases who survived more than 4 months as good prognosis group. Poor prognosis group tended to be higher Glasgow prognostic score(GPS)(p=0.05)and lower serum albumin level(p=0.05)than good prognosis group. GPS and serum albumin level may predict the prognosis of perforated gastric cancer patients.

A Case of Incarcerated and Perforated Stomach in Delayed Traumatic Diaphragmatic Hernia

The patient was an emergency transported, 57-year-old man complaining of left thoraco-lateroabdominal pain, with a history of blunt chest trauma 3 months prior. Thoracoabdominal computed tomography (CT) resulted in a diagnosis of diaphragmatic hernia with incarceration and perforation of the stomach, and same-day emergency surgery was performed. The surgery was performed via an abdominal approach, and after manually repositioning the stomach incarceration, the perforated region was resected and the diaphragm sutured closed. Diaphragmatic hernia can be occasionally difficult to diagnose at the time of initial treatment, and may have been overlooked at the initial presentation, 3 months earlier in the present case. When examining a case of blunt force thoracoabdominal trauma, it is important to keep in mind the possibility of diaphragmatic injury. Additionally, during surgery for traumatic diaphragmatic hernia, in cases where manipulation of the abdominal organs is thought necessary, commencing the surgery with an abdominal approach is desirable.

Surgical Treatment of Splenic Artery Pseudoaneurysm with Digestive Tract Communication - Presentation of Two Cases

Splenopancreatectomy performed for pancreatic pseudo-cyst with splenic artery pseudo-aneurysm and communication with the digestive tract (stomach or colon) is a very rare indication and a small number of these procedures are described in literature. Managing peri-pancreatic pseudo-aneurysm is complex and can be challenging. Surgical treatment is of curative intent and can involve multiple visceral resections. Surgery can be performed in an emergency setting, if the patient presents cataclysmic bleeding, or in a planned manner if the pseudo-aneurysm is discovered incidentally or if the patient manages to overcome the initial bleeding. In this paper we present two cases of pancreatic pseudo-cysts with splenic artery pseudo-aneurysms and communication with the digestive tract (one with pseudo-cystic-colonic communication and the other one with gastric communication). Both patients were males, suffered from chronic pancreatitis and were known to have pancreatic pseudo-cysts. For the treatment of the first patient, surgery was performed in an elective setting, after intensive investigations. The other patient presented with cataclysmic bleeding and emergency surgery was performed in order to control the bleeding. We conclude that surgery remains the main option of treatment for these patients. It can be used as a first line of treatment or secondary to endovascular procedures.

Congenital diaphragmatic eventration complicated with neonatal gastric perforation

Congenital diaphragm eventration is a rare and usually asymptomatic developmental defect. Neonatal gastric perforation is also a rare but lifethreatening condition. In our knowledge, the association of these two pathologies has been, exceptionally reported. We report a case who illustrates clinical and radiological features of this possible co-morbidity. A full-term male neonate was born from uneventful pregnancy and delivery. The antenatal scan was reported as normal. At birth, clinical exam was normal, no special resuscitation was necessary. The newborn was examined and admitted the 4th day of life for fever, tachypnea, cyanosis, hemodynamic shock and refusing feeds. Clinical examination suggested peritonitis. Chest radiography and ultrasonography suggested congenital hernia. A laparotomy was performed after a brief resuscitation and confirmed the presence of diaphragm eventration with gastric perforation. Suturing of gastric perforation with a diaphragmatic plication was performed with favorable evolution.

[Highly Advanced Gastric Cancer Leading to Immediate Perforation on Day Three of Chemotherapy with S-1 plus Oxaliplatin]

A 68-year-old woman was diagnosed with advanced gastric cancer with a type 3 deep ulcer of the middle stomach by endoscopy. An abdominal computed tomography scan revealed multiple lymph node metastases and peritoneal disseminations. The clinical stage was determined to be T4a(SE), N2P1M1(PER), H0 and stage IV . A gastrectomy was scheduled after 2 courses of S-1 plus oxaliplatin(SOX)with curative intent. On day 3 after initiatingSOX therapy, the patient complained of severe abdominal pain. Because the abdominal CT scan showed intra-abdominal free air and a defect in the gastric wall, we performed an emergency total gastrectomy. The defect in the gastric wall was about 1 cm in diameter and was located in the anterior wall of the lower body, consistent with the center of the tumor. The operative findings suggested that the perforation was caused by chemotherapy-induced necrosis of gastric cancer cells. The patient was discharged 16 days after surgery and received post-operative chemotherapy. Our findings suggest that the risk of gastric perforation should be considered when administeringchemotherapy to patients with advanced gastric cancer and a deep ulcer.

[The New Liver Retraction Method "V-Shape+1 Method" Using Penrose Drains for Laparoscopic Surgery of the Stomach]

Liver retraction is a necessary operative procedure for enabling greater visualization and a wider surgical field during laparoscopic surgery of the stomach. We have developed a new liver retraction method for laparoscopic surgery that uses penrose drains, is very easy to perform and in minimally invasive. We call this method the "V-Shape+1 method". We performed laparoscopic surgery using this method on 16 patients within 8.3(5.3-13.7)min(median). We analyzed the postoperative changes in the serum levels of AST, ALT, and T-Bil, which are indicators of liver function. The serum AST, ALT values were elevated at postoperative day 1. Thereafter, the values improved immediately. This early liver function failure is acceptable. We have not experienced any complication related to this method. Therefore, we believe this method is useful for obtaining wide visualization easily for not only laparoscopic gastrectomy but also for laparoscopic upper abdominal surgery.

How to treat stenosis after sleeve gastrectomy?

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) has increasingly gained worldwide acceptance among bariatric surgeons during the past 10 years. Numerous articles have been written about the different approaches to the management of gastric fistulas, but limited data can be found concerning gastric stenosis after LSG.

SETTING

Private hospital, France.

METHODS

A total of 18 patients received endoscopic treatment for stenosis after LSG between May 2007 and June 2015. Stenosis was classified according to the endoscopic findings as functional (the passage of the endoscope was possible, but the sleeve was twisted with various degrees of rotation) or mechanical (the passage of the endoscope was very difficult or impossible).

RESULTS

This study included 13 women and 5 men, with an average age of 37.2±8.4 years and an average body mass index of 41.6±8.7 kg/m². The average number of endoscopic procedures was 1.3 (range, 1-4). No patient had stent migration. The successful rate of endoscopic approach for stenosis of LSG was 94.4%, with one patient requiring conversion to Roux-en-Y gastric bypass. The mean time from the LSG to the first endoscopic intervention was 28.2 days. All patients presented with midsleeve stricture, located near the incisura angularis, and no patient showed a stenosis in the upper part of the gastric tube.

CONCLUSIONS

The treatment of stenosis after LSG must be tailored to the clinical status of the patient and endoscopic findings. Both balloon dilation and stent deployment are useful and safe tools and must be used when appropriate.

Efficacy and Safety of Endoscopic Balloon Dilation for Upper Gastrointestinal Strictures of Crohn's Disease

BACKGROUND

Few articles focused on endoscopic balloon dilation (EBD) in the management of Crohn's strictures in the upper gastrointestinal (GI) tract.

AIMS

The purpose of this study was to evaluate the long-term efficacy and safety of EBD for Crohn's strictures in the upper GI tract and to determine early predictors of response and surgical intervention.

METHODS

All eligible patients who underwent EBD for Crohn's strictures in the upper GI tract were retrospectively reviewed. The long-term success was defined as the recovery of normal diets without surgical intervention over the follow-up period. In order to seek early predictors, patients who achieved long-term success were compared with those who didn't.

RESULTS

A total of 67 dilations of upper GI strictures were performed between June 2011 and March 2015 on 24 patients (mean age 25.6 ± 6.7, 20 male) with Crohn's disease. Technical success was achieved in 62 of 67 dilations (92.5 %) with a complication rate of 3 %. After the median follow-up period of 23.0 months (range 6.2-51.2 months), nine patients underwent surgical intervention, nine patients were still depending on tube feeding; in the meantime, only six (25 %) patients achieved long-term success. Additionally, patients who remained 1 month intervention-free (55.6 vs. 5.9 %, P = 0.015) were more likely to achieve long-term success.

CONCLUSIONS

EBD was a safe procedure, but not a potent therapy for Crohn's upper GI strictures. Meanwhile, 1-month response could serve as an early predictor of the long-term response.

Gastric necrosis secondary to strangulated giant paraesophic hiatal hernia

Asymptomatic giant hiatal hernia comprises a relatively common disease, mostly presented in women with 50 years onwards. The therapeutic approach remains controversial in recent years. Under the latest SAGES`revision, all the symptomatic hernias must be repaired, but the symptomatic hiatal hernia definition isn`t even now established. We present the case os a A 67 - year old woman with an asymptomatic hiatal hernia, that is admitted to our hospital owing to toracic and abdominal pain. This pain was related with food intake for 6 months. The patient presents a clear worsening in the last 24 hours, with no other asociated symptomatology. Suspecting an incarcerated hiatal hernia with stomach perforation, the patient is taken to theatre for a laparotomy during the early hours. An atypic gastrectomy of the greater curvature with a gastropexy is performed with fixation to the anterior abdominal wall. The surgery is completed with a feeding jejunostomy. The Manegement of giant paraesophagic hernias, still remains as one of the challenge of the esophageal surgeons.

Indications for and factors relating to outcome after rumenotomy or rumenostomy in cattle: 95 cases (1999-2011)

OBJECTIVE

To evaluate indications for and factors relating to outcome after rumenotomy or rumenostomy in cattle.

DESIGN

Retrospective case series.

ANIMALS

95 cattle that underwent rumenotomy or rumenostomy.

PROCEDURES

Medical records for 95 cattle that underwent either rumenostomy or rumenotomy at 2 veterinary teaching hospitals in 1999 through 2011 were analyzed. Reasons for the procedures were noted. Long-term outcome was determined during telephone interviews with owners.

RESULTS

42 (44%) bovids underwent rumenostomy and 53 (56%) bovids underwent rumenotomy. Among the 42 animals undergoing rumenostomy, 18 (43%) had rumen cannulas placed during elective procedures. Other indications for rumenostomy included ruminal tympany (bloat [n = 20]), esophageal obstruction (choke [1]), grain overload (1), and provision of access for administration of enteral nutrition (2). Indications for rumenotomy included traumatic reticuloperitonitis (n = 31), bloat (9), foreign body (6), choke (5), and other (2). Long-term follow-up data were available for 31 of 42 (74%) bovids that underwent rumenostomy. Of those 31 animals, 17 (55%) were still in the herd, 4 (13%) had been culled, and 10 (32%) had died or were euthanized. Long-term follow-up data were available for 38 of 53 (72%) bovids that underwent rumenotomy. Of those 38 animals, 13 (34%) were still in the herd, 14 (37%) had been culled, and 11 (29%) had died or been euthanized.

CONCLUSIONS AND CLINICAL RELEVANCE

Results indicated that rumenotomy and rumenostomy can be effective in treating or relieving complications secondary to forestomach disorders in cattle. Bovids undergoing rumen surgery had a favorable prognosis for survival and a fair prognosis for potential return to production.

[A Case of HER2-Positive Esophagogastric Junction Cancer with Perforation Curatively Resected after Neoadjuvant Chemotherapy plus Trastuzumab]

A 60-year-old man was diagnosed with adenocarcinoma of the esophagogastric junction with lymph node metastasis along the left gastric artery. The clinical stage was determined to be T4b, N1, M0, Stage IIIB, and a neoadjuvant chemotherapy (NAC)regimen of capecitabine/CDDP plus trastuzumab was selected for treatment. Before 3 courses of chemotherapy, the patient developed perforated gastric cancer. With conservative therapy, we were able to obtain closure of the perforation without affecting the curability of the cancer. We changed the chemotherapy regimen to S-1/CDDP plus trastuzumab, and the patient underwent curative resection.

Gastric inverted hyperplastic polyp: A rare cause of iron deficiency anemia

Gastric inverted hyperplastic polyp (IHP) is a rare gastric polyp characterized by the downward growth of hyperplastic mucosal components into the submucosal layer. Macroscopically, a gastric IHP resembles a subepithelial tumor (SET); as a result, accurately diagnosing gastric IHP is difficult. This issue has clinical significance because gastric IHP can be misdiagnosed as SET or as malignant neoplasm In addition, adenocarcinoma can accompany benign gastric IHP. Although in most cases, gastric IHPs are asymptomatic and are found incidentally, these polyps may cause anemia secondary to chronic bleeding. Here, we report one case involving gastric IHP accompanied by chronic iron deficiency anemia that was successfully managed using endoscopic submucosal dissection.
