Anastomotic Gastro-Jejunal Ulcer Perforation Following One Anastomosis Gastric Bypass: Clinical Presentation and Options of Management-Case Series and Review of Literature.

BACKGROUND: One anastomosis gastric bypass (OAGB) is an attractive bariatric procedure compared with the gold standard Roux-en-Y gastric bypass (RYGB) with one less anastomosis. Thousands of these procedures have now been performed by different surgeons who believe that it could hold fewer complications than RYGB. However, postoperative complications including the formation of anastomotic ulcers and possible perforation remain a main concern following OAGB. METHODS: We report three cases of perforation of an ulcer at the gastro-jejunal anastomosis following laparoscopic one anastomosis gastric bypass. All cases needed surgical intervention after adequate resuscitation. RESULTS: All patients were successfully managed using a minimally invasive approach with different techniques of repair (primary suturing of the perforation or resection and conversion to Roux-En-Y gastric bypass). All patients did well and were discharge in a stable condition after 4-5 days. CONCLUSION: Perforation of an anastomotic ulcer post-one anastomosis gastric bypass is a serious condition and can be a life threatening complication. A high index of suspicion helps to diagnose these cases in patients presenting with acute abdomen following OAGB. Adequate resuscitation and repair of the perforation are main lines of treatment. Definitive surgical option depends on the general condition of the patient, timing of presentation, size and site of the perforation, and experience of the surgeon.

Gastric Remnant Perforation Caused by Peterson's Hernia Following One Anastomosis Gastric Bypass: a Rare Complication.

INTRODUCTION: One anastomosis gastric bypass (OAGB) has gained popularity over the recent years; it appears to be an effective bariatric procedure with acceptable weight loss, co-morbidity resolution, and complication rates in the short and medium term. However, it still continues to have concerns in the bariatric community due to a spectrum of potential complications. To our knowledge, there are few published cases of internal hernia, but no published reports of gastric remnant perforation following OAGB. CASE PRESENTATION: We report a case of a 32-year-old female who developed a perforation of the remnant stomach along the gastric fundus secondary to bowel obstruction 5 years after OAGB. The perforation was managed by stapled resection of the perforated fundus and closure of Peterson's space for potential hernia as a causative factor, and the patient had a smooth postoperative recovery. DISCUSSION: Early diagnosis is crucial in post bariatric emergencies with a low threshold of early intervention. Gastric remnant perforation was previously described in some reports following Roux-en-Y gastric bypass (RYGB) but not after OAGB. Etiology of perforation can be rationalized to primary gastric remnant pathology or secondary to external factors such as back pressure of mechanical/functional bowel obstruction. CONCLUSION: Peterson's hernia and gastric remnant perforation are rare, yet serious, complications that need to be kept in mind while dealing with post-OAGB patients presenting with abdominal pain. Early diagnosis and treatment are essential for a better outcome.

Spontaneous Splenic Rupture Two Weeks After Sleeve Gastrectomy.

Sleeve gastrectomy is one of the commonest bariatric procedures performed globally with an acceptable rate of reported complications. Splenic injury during this procedure is a rare but can be a serious complication. A 32-year-old male patient who had a spontaneous splenic rupture two weeks after an uneventful sleeve gastrectomy needed an emergency splenectomy. Spontaneous rupture after sleeve gastrectomy is an extremely rare condition with one single previous report. Diagnosis needs a high clinical suspicion and treatment is usually by splenectomy if not responding to resuscitative measures. Such cases need adequate further workup to exclude other causes of rupture. Considering the high number of sleeve gastrectomy procedures done worldwide, this report highlights the importance of high suspicion and awareness of physicians who face patients with post-bariatric complications. Early diagnosis and intervention are usually important factors in better outcome.

Role of routine upper endoscopy before bariatric surgery in the Middle East population: a review of 1278 patients.

Introduction The routine use of preoperative endoscopy for patients undergoing bariatric surgery is controversial. Although many surgeons find it unnecessary, others still consider it a mandatory tool in preoperative assessment. Patients and methods We reviewed the medical records of all patients who had undergone preoperative endoscopy before bariatric surgery in Rashid Hospital between January 2013 and June 2016. The patients were divided into three groups: Group 0 included patients with normal endoscopy; Group 1 included patients with abnormalities that did not affect the timing or type of procedure; Group 2 included patients with abnormalities that had a direct impact on the procedure. Results The files of 1473 patients were reviewed. Endoscopy results were not present in 195 files, so those patients were excluded, and the remaining 1278 files were included. The mean age of patients was 41.3 ±â€Š12.7 years, 61 % were female and 39 % were male. The mean body mass index (BMI) was 43.7 ±â€Š8 kg/m 2 . Endoscopy was normal in 10.6 % of patients and abnormal in 89.4 %. The most common abnormalities were gastritis, positive Campylobacter-like organism test (CLO test), gastroesophageal reflux disease (GERD) with esophagitis and hiatal hernia. Group 0 included 10.6 % of patients (n = 135), Group 1 included 25.6 % of patients (n = 327), while Group 2 included 63.8 % of patients (n = 816). Conclusion Routine endoscopy seems to play an important part in the preoperative preparation of patients planned for bariatric surgery in the Middle East population. Further studies or meta-analysis could help in building up clear solid evidence and guidelines that could be approved by international bariatric associations with regard to indications for preoperative upper endoscopy in bariatric patients.

Role of Routine Abdominal Ultrasound Before Bariatric Surgery: Review of 937 Patients.

INTRODUCTION: Routine use of preoperative abdominal ultrasound for patients undergoing bariatric surgery is controversial. Despite that some physicians routinely implement it, others consider it unnecessary and not cost effective because it does not have a clear clinical significance in the preparation of bariatric patients. AIM OF THE STUDY: To investigate whether routine abdominal ultrasound prior to bariatric surgery affects the surgical plan or not. PATIENTS AND METHODS: We reviewed medical records of patients with abdominal ultrasound before bariatric surgery in Rashid Hospital between June 2014 and December 2016. Patients were divided into four groups: group 0 included patients with normal abdominal ultrasound, group 1 included abnormalities that did not affect timing or type of procedure, group 2 included findings that did not affect surgical plan but needed postoperative follow-up, and group 3 included abnormalities that had a direct impact on the procedure. RESULTS: One thousand one hundred twenty files were reviewed. Results were missing in 183 files, thus excluded; remaining 937 files were included. Mean age of patients was 37 ± 12 years, 589 (63%) were females and 348 (37%) were males. Mean BMI was 45.1 ± 9.8 kg/m2. Ultrasound was normal in 354 (37.7%) of patients and abnormal in 583 (62.3%). CONCLUSION: Routine abdominal ultrasound does not seem to have an important part in preoperative preparation of patients before bariatric surgery. Further studies could be helpful in discussing this role and building up clear solid evidence and guidelines that could be approved by international bariatric associations regarding the indication of preoperative abdominal ultrasound before bariatric surgery.

The First Consensus Statement on One Anastomosis/Mini Gastric Bypass (OAGB/MGB) Using a Modified Delphi Approach.

BACKGROUND: An increasing number of surgeons worldwide are now performing one anastomosis/mini gastric bypass (OAGB/MGB). Lack of a published consensus amongst experts may be hindering progress and affecting outcomes. This paper reports results from the first modified Delphi consensus building exercise on this procedure. METHODS: A committee of 16 recognised opinion-makers in bariatric surgery with special interest in OAGB/MGB was constituted. The committee invited 101 OAGB/MGB experts from 39 countries to vote on 55 statements in areas of controversy or variation associated with this procedure. An agreement amongst ≥ 70.0% of the experts was considered to indicate a consensus. RESULTS: A consensus was achieved for 48 of the 55 proposed statements after two rounds of voting. There was no consensus for seven statements. Remarkably, 100.0% of the experts felt that OAGB/MGB was an "acceptable mainstream surgical option" and 96.0% felt that it could no longer be regarded as a new or experimental procedure. Approximately 96.0 and 91.0% of the experts felt that OAGB/MGB did not increase the risk of gastric and oesophageal cancers, respectively. Approximately 94.0% of the experts felt that the construction of the gastric pouch should start in the horizontal portion of the lesser curvature. There was a consensus of 82, 84, and 85% for routinely supplementing iron, vitamin B12, and vitamin D, respectively. CONCLUSION: OAGB/MGB experts achieved consensus on a number of aspects concerning this procedure but several areas of disagreements persist emphasising the need for more studies in the future.

Phytobezoar impaction in a Meckel's diverticulum; a rare cause of bowel obstruction: Case report and review of literature.

INTRODUCTION: Meckel's diverticulum is the most common anomaly of the gastrointestinal tract, occurring in 1-3% of the general population. The most common complication of Meckel's diverticulum is intestinal obstruction. In this report, we describe a rare cause of intestinal obstruction due to Meckel's; the phytobezoar. After thorough literature review, the authors found about ten individual reports of the same topic. In all these cases, diagnosis was established intra-operatively. CASE PRESENTATION: A forty-seven-year old male presented to the emergency department with a one-day history of abdominal pain associated with vomiting and constipation. Physical examination diagnostic tests revealed features of intestinal obstruction. DISCUSSION: The lifetime risk of complications in patients with a Meckel'sdiverticulum is usually small and occurs only in up to 4%. In adults' intestinal obstruction is the most common complication (40%). CONCLUSION: Complicated Meckel's diverticulum can have different clinical presentations and can cause bowel obstruction. An association with bezoars impaction is possible and it should be suspected in adult patients presenting with bowel obstruction of unknown causes especially those with high vegetarian diet.

Traumatic Jejunal hematoma in childhood-A case report and review of literature.

INTRODUCTION: Intramural jejunal hematoma is a very rare condition with only few cases reported in the literature. It rarely occurs spontaneously, and is mostly seen in hemophiliac patients and is also associated with abdominal trauma. It occurs more commonly in children than in adults and can present with features of intestinal obstruction. CASE PRESENTATION: A 10year old boy presented with features of intestinal obstruction. He sustained a blunt abdominal trauma two days prior to presentation. Abdominal computed tomography (CT) revealed jejunal hematoma with signs of complete obstruction. A trial of non-operative management failed and eventually he was managed surgically. DISCUSSION: Blunt trauma to the abdomen is the principle cause of jejunal hematoma. The trauma in majority of cases is trivial and usually the patients present late. The symptoms range from mild abdominal pain to intestinal obstruction with acute abdomen. A trial of conservative management is justifiable in stable patient. If no clinical improvement surgical intervention is indicated. CONCLUSION: Intramural jejunal hematoma after blunt abdominal trauma is seen predominately in pediatric age group and can present as intestinal obstruction. It should be suspected when a child presents with intestinal obstruction and a concurrent history of blunt abdominal trauma. The mainstay of treatment is surgical intervention. Because of the rarity of this disease, the role of conservative therapy is undefined.

Pericardio-diaphragmatic rupture following blunt abdominal trauma: Case report and review of literature.

INTRODUCTION: Traumatic diaphragmatic rupture (TDR) occurs in 0-5% of patients with major blunt thoraco-abdominal trauma, in most of them on the left side, and an early correct diagnosis is made in less than half of the cases (Meyers and McCabe, 1993; Ball et al., 1982). PRESENTATION OF THE CASE: We report a case of a forty-eight years old man who had a pericardio-diaphragmatic rupture after a high-velocity blunt abdominal trauma that was diagnosed and treated successfully. DISCUSSION: Pericardio-diaphragmatic rupture (PDR) is an uncommon problem that poses a diagnostic challenge to surgeons. The incidence of PDR is between 0.2% and 3.3% of cases with TDR (Sharma, 1999 [3]). CONCLUSION: PDR should be suspected in any patient with high velocity thoraco-abdominal trauma. Early diagnosis is essential and needs a high index of suspicion. Early Management is important in decreasing morbidity and mortality.

Gastric Perforation following Intragastric Balloon Insertion: Combined Endoscopic and Laparoscopic Approach for Management: Case Series and Review of Literature.

BACKGROUND: Obesity is a serious disease, with substantial morbidity and mortality. The endoscopic placement of an intragastric balloon (IGB) in association with a low-calorie diet is an option for the treatment of obesity. IGB complications include dislocation of the balloon causing intestinal obstruction, upper gastro-intestinal bleeding and perforation, especially during balloon insertion or removal. Our work aims at decreasing the morbidity of open laparotomy in the management of such gastric perforations. METHODS: We report three cases of gastric perforation following IGB insertion that needed surgical intervention. Decision was made to treat them with a minimally invasive combined endoscopic and laparoscopic approach to decrease postoperative morbidity. RESULTS: All patients were successfully treated by a minimally invasive approach with less morbidity than the conventional open laparotomy. CONCLUSION: Gastric perforation should be suspected in any patient with IGB who presents with an acute abdomen. This can be managed with a minimal invasive approach.
