2. Chronic pain after two laparoendoscopic inguinal hernia repairs compared with laparoendoscopic repair followed by the Lichtenstein repair: an international questionnaire study. (Abstract)

Chronic pain after two laparoendoscopic inguinal hernia repairs compared with laparoendoscopic repair followed by the Lichtenstein repair: an international questionnaire study. The best repair of a recurrent inguinal hernia after primary laparoendoscopic repair is debatable. The aim was to assess chronic pain after two laparoendoscopic repairs in the same groin compared with Lichtenstein reoperation preceded by a laparoendoscopic repair.This cohort study included adult patients who had received (...) two laparoendoscopic repairs (Lap-Lap) or a laparoendoscopic repair followed by the Lichtenstein repair (Lap-Lich). Eligible patients were identified in the Danish and the Swedish hernia databases. Lap-Lap was matched 1:3 with Lap-Lich, and patients were sent validated questionnaires. The primary outcome was the proportion with chronic pain-related functional impairment, compared between the two groups. Secondary outcomes included chronic pain during various activities.In total, 74% (546 patients

3. Internal hernia from the interureteric space after robot-assisted radical cystectomy and urinary diversion: Two case reports. Full Text available with Trip Pro

Internal hernia from the interureteric space after robot-assisted radical cystectomy and urinary diversion: Two case reports. Radical cystectomy and urinary diversion remains the definite management for muscle invasive bladder urothelial cancer. Internal herniation caused by ureteral adhesion is an extremely rare complication after the procedure. To the best of our knowledge, this is the first case report of small bowel obstruction and internal herniation occurring between bilateral ureters (...) patients underwent open ureterolysis and internal hernia reduction. During the operation, bowel loop herniation between the interureteral spaces were found.Both patients recovered smoothly after second operation.The incidence of internal herniation may increase by the growing use of RARC. Suitable stoma position, appropriate length of ureter dissection, and retroperitonealization can help prevent this complication.

4. Obesity is a risk factor for internal hernia after laparoscopic or robot-assisted gastrectomy with mesenteric defect closure for gastric cancer. (Abstract)

Obesity is a risk factor for internal hernia after laparoscopic or robot-assisted gastrectomy with mesenteric defect closure for gastric cancer. Internal hernia (IH) is a life-threatening complication after gastrectomy. The increase in the frequency of minimally invasive surgery is considered to be related to the increase in the frequency of IH, and mesenteric defect closure has been recommended to reduce this complication. However, IH can occur even when mesenteric defects are closed, so

Internal hernia after gastrectomy for gastric cancer in minimally invasive surgery era. The incidence and clinical presentation of internal hernia after gastrectomy have been changing in the minimally invasive surgery era. This study aimed to analyze the clinical features and risk factors for internal hernia after gastrectomy for gastric cancer.We retrospectively analyzed internal hernia after gastrectomy for gastric cancer in 6474 patients between January 2003 and December 2016 at Seoul (...) National University Bundang Hospital. Multivariable logistic regression was performed to evaluate risk factors.Internal hernias identified by computed tomography or surgical exploration were 111/6474 (1.7%) and the median interval time was 450 days after gastrectomy. Fourteen (0.9%) of the 1510 patients who underwent open gastrectomy and 97 (2.0%) of the 4964 patients who underwent laparoscopic gastrectomy developed internal hernia. Of the 6474 patients, internal hernia developed in 0 (0%), 9 (1.1

6. Internal Hernia After Laparoscopic Gastric Bypass: Effect of Closure of the Petersen Defect - Single-Center Study. (Abstract)

Internal Hernia After Laparoscopic Gastric Bypass: Effect of Closure of the Petersen Defect - Single-Center Study. Bowel obstruction due to internal hernia (IH) is a well-known late complication of a laparoscopic roux-en-y gastric bypass (LRYGBP). The objective of this study is to evaluate if closure of the mesenteric defect and Petersen's space will decrease the rate of internal hernias compared to only closure of the mesenteric defect.A single-center retrospective descriptive study (...) the diagnosis in only 73%. In group A, including 1586 patients, 53 (3.34%) were diagnosed with an internal hernia: 39 at Petersen's space and 14 at the mesenteric defect. The mean time interval was 24.2 months and the mean BMI 25.7 kg/m2. After routine closure of the Petersen defect in 1538 patients in group B, an internal hernia during laparoscopy was found in 14 (0.91%) patients after a mean period of 13.5 months: 11 at Petersen's space and 3 at the mesenteric defect.

8. Closed Loop Obstruction from Epiploic Appendage Adhesion Mimicking Pericecal Internal Hernia Full Text available with Trip Pro

Closed Loop Obstruction from Epiploic Appendage Adhesion Mimicking Pericecal Internal Hernia Internal hernias involve herniation of viscera into an abdominal compartment through a defect in the mesentery or peritoneum. Herniation may occur through normal anatomic structures or through pathologic defects secondary to congenital abnormality, inflammation, trauma, or surgery. Patients with an internal hernia most commonly present with acute bowel obstruction. While internal hernia is an uncommon (...) cause of bowel obstruction, making up approximately 0.2-0.9% of cases (Choi, 2017), the incidence is increasing due to greater use of techniques such as Roux-en-Y for liver transplant and gastric bypass. There are multiple types of internal hernia, including paraduodenal, Foramen of Winslow, sigmoid mesocolon, pericecal, transmesenteric, transomental, supravesical, and pelvic. We present a case in which a transverse colon epiploic appendage adhesion to the ascending colon mesentery resulted

in the distal transverse colon, mesenteric swirling and a distended cecum, consistent with cecal, rather than sigmoid, volvulus. Upon surgical exploration the majority of the small bowel, cecum and ascending colon had herniated through the transverse mesocolon defect created during her prior gastric bypass. The bowel was reduced through the mesenteric defect, and an ileocecectomy was performed. This is, to our knowledge, the first reported case of cecal volvulus caused by an internal hernia through (...) Cecal volvulus caused by internal herniation after roux-en-y gastric bypass surgery Cecal volvulus is the rotation of a mobile cecum resulting in a large bowel obstruction. We present the case of a 55-year-old female who underwent a roux-en-y gastric bypass in 2003 and presented to the emergency department with worsening abdominal pain, distention and obstipation. Roentgenogram demonstrated a 14 cm colon suggestive of sigmoid volvulus, but CT scan showed rectal contrast abruptly ending

14. Petersen's Space Internal Hernia after Laparoscopic One Anastomosis (Mini) Gastric Bypass Full Text available with Trip Pro

Petersen's Space Internal Hernia after Laparoscopic One Anastomosis (Mini) Gastric Bypass One anastomosis gastric bypass (OAGB) is now considered as an appropriate alternative for Roux-en-Y gastric bypass (RYGB) with some advantages such as absence of risk for internal hernia (IH). But, is really the risk of IH equal zero after OAGB? Case Summary. A 37-year-old male was admitted due to severe abdominal crampy pain, nausea, vomiting, and obstipation. He had chronic and intermittent abdominal (...) pain from 2 years after OAGB. With high suspicion of complete obstruction, the exploratory laparoscopy was performed. Intraoperative findings showed incarcerated bowel hernia from Petersen's defect. The incarcerated bowel was reduced, and the defect was repaired. The patient was discharged 2 days after operation.The incidence of IH after OAGB is rare but not zero. In any suspicious signs and symptoms for IH, the early exploratory laparoscopy is mandatory to diagnose and treat.

16. Predictive value of abdominal CT in evaluating internal herniation after bariatric laparoscopic Roux-en-Y gastric bypass. (Abstract)

Predictive value of abdominal CT in evaluating internal herniation after bariatric laparoscopic Roux-en-Y gastric bypass. Internal herniation, a serious complication after bariatric surgery, is challenging to diagnose. The aim of this study was to determine the accuracy of abdominal CT in diagnosing internal herniation.The study included consecutive patients who had undergone laparoscopic gastric bypass surgery between 1 January 2011 and 1 January 2015 at a bariatric centre of excellence (...) . To select patients suspected of having internal herniation, reports of abdominal CT and reoperations up to 1 January 2017 were screened. CT was presumed negative for internal herniation if no follow-up CT or reoperation was performed within 90 days after the initial CT, or no internal herniation was found during reoperation. The accuracy of abdominal CT in diagnosing internal herniation was calculated using two-way contingency tables.A total of 1475 patients were included (84·7 per cent women, mean age
