Product identification records for the alleged gore device were not provided.Therefore, a review of the manufacturing records could not be performed.Additional details regarding the patient's clinical course were ascertained from a review of medical records and are as follows: relevant medical information: on (b)(6) 2004: (b)(6) operative report.Preoperative diagnosis: morbid obesity.Postoperative diagnosis: morbid obesity.Operation/procedure: laparoscopic gastric bypass, 30 cc gastric pouch, 100 cm jejunal limb.¿the patient was then awakened, extubated and taken back to the recovery room in stable condition.¿ on (b)(6) 2005: (b)(6) history and physical.Patient had history of morbid obesity, for which she underwent roux-en y gastric bypass surgery on (b)(6) 2004, and lost approximately 130 pounds.Did well postoperatively until approximately 4-5 months ago when she began to complain of some persistent abdominal discomfort, as well as some nausea, vomiting associated with pain.Patient developed umbilical hernia, as well as gallstones, and both issues resolved surgically.Follow these surgeries patient continued to do poorly complaining of, again persistent pain, nausea and vomiting.Underwent ct which revealed findings consistent with possible malrotation of large bowel with cecum located in left upper quadrant of abdomen and single dilated loop of small bowel in right upper quadrant.Medication include prevacid.History of gastroesophageal reflux disease.Surgical history cesarean section in 1988, 1994, 1985; laparoscopic cholecystectomy in (b)(6) 2005, and umbilical hernia repair.Weight (b)(6), height 5 feet 4 inches.Exam: exhibit some mild tenderness in periumbilical area on deep palpation.No masses noted.Old incisions are well-healed.Plan: exploratory laparoscopy with intraoperative egd.On (b)(6) 2005: (b)(6) operative report.Operation/procedure: esophagogastroduodenoscopy.¿the endoscope was withdrawn and the patient tolerated that [sic] the procedure well.Then the abdominal procedure was then started.¿ on (b)(6) 2005: (b)(6) operative report.Preoperative diagnosis: abdominal pain.Possible partial small bowel obstruction secondary to internal hernia.Postoperative diagnosis: normal esophagogastroduodenoscopy.Partial small bowel obstruction secondary to petersen¿s hernia.Appendicitis.Incisional hernia.Operation/procedure: egd.Laparoscopy with adhesiolysis.Open laparotomy with repair of petersen¿s internal hernia.Appendectomy.Incisional hernia repair.Assistant: (b)(6).Anesthesiologist: (b)(6) description of operation/procedure: ¿the patient was taken to the operating room after being prepped and draped sterilely and given general anesthesia.Veress needle was inserted just above the umbilical region with negative pressure to the region and 3 l of c02 was then used to insufflate the peritoneal cavity.Once that was done, then a 5-mm right-side port had been inserted, another one inserted in the left upper quadrant region, one in the right upper quadrant region and another one in the left mid quadrant region.Once these are in place multiple adhesions are then encountered, and these are taken down.The abdomen is explored and it is noted that the ____ is coming down, and there is a twist within it¿s [sic] mesentery, so the cecum is then located.It is located in the left upper quadrant region, what appears to be in the internal hernia.Attempts were made to try and get this out.We could not get it out because it appeared to be attached to something, so we could not do this.A serosal tear was noted on the small bowel, and this was repaired laparoscopically with 3-0 gi silks.Three of these were used.After multiple attempts to again reduce the hernia, i was unable to do it, so i elected, now after about an hour and a half of attempting this, to open up the abdomen.The abdomen was converted to open, and it was noted that she had an incisional hernia on the bottom part of the incision approximately 6 x 6 cm in size.Once the abdominal cavity was entered then exploration was then done.It is noted that the cecum is stuck to the transverse mesocolon, but it is stuck there with the appendix.The appendix is firm and fibrotic and some inflammation is noted to the attachment on the transverse colon.This is what kept the cecum from being able to be removed from the internal hernia.An appendectomy was then performed by ligating the mesenteric vessels with 3-0 silk.Then the appendix was then doubly ligated with 0 chromic and then the appendix was doubly clamped and removed from the field.The stump was cauterized.The patient still had an internal hernia, and what i found was that almost the entire part of the small bowel, including the cecum, had gone through a petersen¿s hernia, and then this was successfully removed.The petersen¿s hernia defect was now obliterated by applying multiple sutures of 3-0 silk onto the small bowel mesentery and to the transverse colon.Thus, the defect was obliterated, and the bowel was then placed back in its normal position.The wound is now copiously irrigated.A piece of seprafilm was then applied onto the small bowel, and then the incisional hernia repair was then repaired by finding the bordered and removing the hernia sac.The defect was then closed using multiple and interrupted sutures of figure-of-eights of #1 prolene, and then the skin was closed with 4-0 monocryl.Sterile dressings were applied.The patient tolerated the procedure well and send back to recovery room in stable condition.¿ on (b)(6) 2005: (b)(6) discharge summary.History: admitted with abdominal pain.Underwent egd and laparoscopy with adhesiolysis.Started out laparoscopically and had to be converted to open repair, as she had internal hernia.Also had incisional hernia which was repaired at the time.Postoperatively did well.Ambulatory, tolerated full liquids and taking oral pain meds.Discharged home in stable condition.On (b)(6) 2005: (b)(6) operative report.Preoperative diagnosis: incidental carcinoid tumor.Postoperative diagnosis: incidental carcinoid tumor.Operation/procedure: right hemicolectomy.¿the patient tolerated the procedure well and was sent back to the recovery room in stable condition.¿ on (b)(6) 2006: (b)(6) discharge summary.Admission date: (b)(6) 2005.Discharge date: (b)(6) 2006.This patient had incidental findings of carcinoid tumor.Brought back and underwent right hemicolectomy.Postoperatively, did remarkably well.Final diagnosis: incidental carcinoid tumor finding.On (b)(6) 2006: (b)(6) operative report.Preoperative diagnosis: small bowel obstruction.Multiple incisional hernias.Postoperative diagnosis: small bowel obstruction.Multiple incisional hernias.Operation/procedure: exploratory laparotomy with reduction of the small bowel obstruction and repair of an internal hernia mesenteric defect.Repair of multiple incisional hernia.Assistant: (b)(6) anesthesiologist: (b)(6) description of operation/procedure: ¿the patient was taken to the operating room and placed in the supine position.After being prepped and draped sterilely and given general anesthesia, an incision was made in the midabdomen and carried down to the end of the abdominal cavity.Along the opening there are multiple incisional hernias, anywhere from 2-4 cm in size.Once we entered the abdomen the balfour retractor is applied.Exploration reveals that there is a mesenteric defect in which approximately 12 inches of small bowel is trapped.This is gently removed from the mesenteric defect and thus the obstruction is relieved.The inspection of the roux limb is then done.The jejunojejunostomy and the entire small bowel is otherwise unremarkable.This patient had previous carcinoid tumor found in the appendix and there is no evidence of recurrence.The mesenteric defect is now closed with a running suture of 2-0 ethibond.No other findings are found at this time.Closure and repair of the incisional hernia is then done.The fascia is ___ delineated and a running suture of #1 prolene is then applied, one from below, one from above; thus, obliterating the hernia defects.There are no other findings at this point.The wound is anesthetized and closure of the wound is done using 2-0 vicryl in subcutaneous tissue, and 4-0 monocryl on the skin.Sterile dressings are applied.The patient tolerated the procedure well and was sent back to the recovery room in stable condition.¿ on (b)(6) 2006: (b)(6) discharge summary.Admission date: (b)(6) 2006.Discharge date: (b)(6) 2006.History: patient admitted for partial bowel obstruction.Taken to surgery on (b)(6) and underwent repair of small bowel obstruction.She had internal hernia and multiple incisional hernias, which were repaired.Postoperative day 1 she was ambulating well.Her nasogastric tube was minimal and so it was removed.By the 5th she was tolerating some liquids; however, she had no flatus.Her abdominal exam removed [sic] clean.By (b)(6) she was doing well.Wounds were well healed and she was able to tolerate a diet without difficulty.Discharged home in stable condition.Return to office in 1 week.Final diagnosis: partial bowel

operating room and placed in the supine position after being prepped and draped sterilely and given general anesthesia.The incision was made in the midline and it was carried down into the abdominal cavity.Adhesions were encountered and these were taken down sharply.A hernia sac was also found and then removed.This left a defect of approximately 8 inches x 4 inches in size and so a piece of dual mesh of 8 inches x 6 inches in size was then applied and anchored with a gore-tex suture all over the lateral edges.It was finally secured into good position.It was tension free.There was no bleeding.The wound were then copiously irrigated with antibiotic solution and then the skin was reapproximated using 3-0 vicryl in interrupted fashion and then the skin was closed using 4-0 monocryl.Sterile dressings were then applied and double binders applied.The patient was then awakened, extubated and taken back to the recovery room in stable condition.¿ relevant medical information:

emergency room.Onset of abdominal pain for past couple of days.Previous laparoscopic gastric bypass for weight loss surgery approximately 3 to 4 years ago.This resulted in her then coming back and having a partial small bowel obstruction, at which times a large appendix was removed, and this revealed a carcinoid.Came back to have extended right hemicolectomy for that surgery.She then had multiple incisional hernias, the last one being repaired earlier in the year with placement of mesh.That subsequently got infected and had to be removed and was primarily closed approximately 3 weeks ago.Followed up in office for some drainage from the wound.Had been on antibiotics, but did not seem to help.An abdominal ct was done which revealed an inflammatory area in lower part of incision.Admitted with intravenous antibiotics and possible drainage.She does not smoke or drink.Exam: 2 areas that are slightly open with minimal drainage.Area is tender to touch.On (b)(6) 2009: (b)(6).Operative report.Preoperative diagnosis: abdominal wall abscess.Postoperative diagnosis: abdominal wall abscess.Operation/procedure: incision and drainage of a 4 x 6 cm abdominal wall abscess.Assistant: (b)(6).Description of procedure: ¿the patient is taken to the operating room.After being prepped and draped sterilely and given general anesthesia, an incision was made down on the lower abdominal part of the incision, carried down approximately 3 to 4 cm deep and there was an abscess cavity which was then irrigated and drained and debrided.Cultures were taken of this.Once that is done, after the area is copiously irrigated with antibiotic solution, it is now packed with antibiotic-soaked 4 x 8¿s.Sterile dressing were then applied.She was then awakened, extubated and taken back to recovery room in stable condition.¿ on (b)(6) 2009: (b)(6) history and physical.Presented today for wound care but also secondary to findings of excessive drainage of particulate matter from her incision.This was found to have food particles draining from her midline incision and this it was obvious that she is have a communicating fistula between her intestine and her skin.In light of the finding she was admitted to the medical/surgical floor for evaluation.On (b)(6) 2009: (b)(6).Operative report.Preoperative diagnosis: enterocutaneous fistula.Wound infection.Postoperative diagnosis: enterocutaneous fistula.Wound infection.Operation/procedure: exploratory laparotomy with a small bowel resection.Debridement of the wound.Assistant: (b)(6), medical student.Anesthesiologist: (b)(6).Description of operation/procedure: ¿the patient was taken to the operating room.She was placed in the supine position.After being prepped and draped sterilely and given general anesthesia, an incision is made in the midline and carried down through the old pds sutures.Once the abdomen is entered, the small bowel that has the perforation and fistula come into the wound is then located.The abdomen internally was adhesion free and so that segment of bowel was brought up that had the perforation.It is approximately 1 cm in diameter.So then the bowel is brought up out of the wound using the gi stapler with the blue staples.This is fired proximally and distally to where the opening is, and then that segment is resected and removed.A stay suture of 3-0 silk is then applied to those 2 ends of the bowel and then side to side anastomosis is then done again by application of another gi stapler using the blue staples.Once small openings were made in the small bowel, the stapler is then introduced into those openings and the device is now fired and removed.There is no bleed along the staple line.So then that opening is then sutured closed with multiple interrupted sutures 3-0 silks as well the mesentery is also closed with 3-0 silks.This makes a new anastomosis in a side-to-side fashion, approximately 3.5 cm in size.There is no ischemia.No bleeding.No tension on the anastomosis.So it is now placed back into the abdominal cavity.The wound is then irrigated with antibiotic solution and then closure of the midline incision is done with multiple interrupted sutures of #1 prolene.The area is anesthetized with 0.25% marcaine.Approximately 20 ml is used.Then the skin is closed with staples, and packing is used into the wound where the prior infection was at.Sterile dressing was then applied.She is then awakened, extubated, and taken back to recovery room in stable condition.¿ on (b)(6) 2009: (b)(6).Discharge summary.Admission date: (b)(6) 2009.Discharge date: (b)(6) 2009.History/hospital course: came in because he had a previous incisional wound abscess, which was opened up, approximately 4-5 days ago.She came back to clinic and now she was draining bile from her midline wound.So, it was suspected that the patient had enterocutaneous fistula.She was admitted, started on total parenteral nutrition and cone she was stabilized from that, she was taken to surgery on (b)(6) 2009.Tolerated procedure well postoperatively.Started on liquids postoperative day 2.Tolerated these, total parenteral nutrition weaned off.Wound remained clean and healed well, as we left that one area where the wound was opened.Discharged in stable condition.Return to office in 1 week time.Final diagnosis: enterocutaneous fistula.On (b)(6) 2009: (b)(6).Office notes.Status post small bowel resection now doing better at home with wound changes.Exam: open wound approximately 3 x 4 inches in size.Impression: open wound but healing.Plan: start
