reperforation

reperforation

[rē‚pər·fə′rā·shən]
(petroleum engineering)
Creation of new perforations (holes) in oil well tubing opposite to oil-bearing reservoir zones; creates more opportunity for fluid to drain from the formation into the wellbore.

Five (14.2%) cases underwent re-laparotomy due to early post-operative complications, as follows: reperforation in two (5.7%) patients (patients with intestinal tuberculosis and volvulus of the stomach), intraabdominal abscess in two (5.7%) patients, and anastomosis leak in one (2.8%) patient.
Postoperative complications like wound infection, wound dehiscence, reperforation or anastomotic leak, septicaemia, respiratory complications and mortality was recorded.
Since there was reperforation of the donor duodenum at the previous perforation site, a 3.5 mm silicon tube (Lilia drain) was inserted through the perforation into the duodenum as a second intestinal tube and was anchored with a purse-string suture.
However, the risk of secondary leakage due to reperforation cannot be excluded [13].
Our three outcomes measures were (1) anatomic success rates at 3 months, (2) hearing results at 6 months, and (3) rates of morphologic success (i.e., the absence of reperforation, retraction, and graft displacement) at 2 years among those in each group who had an intact graft at 3 months.
The postoperative outcomes were collected over a 36-month follow-up period and included whether or not there was eradication of the underlying disease with initial TPK, the use and type of any adjunctive surgical measures to facilitate postoperative graft healing, the presence of graft clarity after initial TPK, whether or not reperforation occurred following the initial TPK, occurrence of regrafting after the initial TPK, the total number of corneal grafts received during the study interval, whether or not the patient received a Boston Type 1 Keratoprosthesis, the postoperative BCVA at 36 months, and whether or not the operative eye underwent enucleation/evisceration.
Tympanic reperforation in myringoplasty: evaluation of prognostic factors.
During each followup, every patient underwent otoscopy & EUM to assess the graft uptake/graft rejection or reperforation, presence or absence of any ear discharge (dry ear achieved or not).
Many different materials have been used to reconstruct the tympanic membrane with the goals of achieving a high initial graft integration rate, a low rate of reperforation, and normal hearing.
During each followup, every patient underwent otoscopy and EUM to assess the graft uptake/graft rejection or reperforation, presence or absence of any ear discharge (dry ear achieved or not).
A study of tympanoplasty procedures in Finland many years ago showed that the likelihood of a tympanic membrane reperforation was greater in patients who had P aeruginosa infections preoperatively.
Simple omental patch by open method and Helicobacter pylori eradication therapy is sufficient to prevent reperforation. (22) B.
