This report highlights the rare occurrence of a huge gangrenous Meckel's diverticulum in an adult, which was managed successfully with laparoscopic resection. A 45-year-old woman presented with a one-day history of right iliac fossa pain with fever and vomiting. Computed tomography showed a huge gangrenous Meckel's diverticulum. The patient underwent laparoscopic exploration and extracorporeal stapled resection of the Meckel's diverticulum. This case serves to highlight the safety and feasibility of performing a laparoscopic resection of a huge gangrenous Meckel's diverticulum in an adult.

PURPOSE: Malnutrition is associated with an increased risk of developing complications following gastrointestinal surgery, especially following radical surgeries such as pelvic exenteration. This study aims to determine if preoperative body mass index (BMI) is associated with 30-day morbidity, length of hospital stay and/or quality of life (QoL) in patients undergoing pelvic exenteration surgery for recurrent and locally-advanced rectal cancer prior to a prospective trial. METHODS: A review of all patients who underwent pelvic exenteration surgery prior to 2008 was performed. Patients were included if they had a documented BMI as well as a QoL measurement (Functional Assessment Cancer Therapy - Colorectal questionnaire). RESULTS: Thirty-one patients, with a mean age of 56 years, had preoperative height and weight data, as well as measures of postoperative QoL, and formed the study group. The numbers of patients with recurrent (n = 17) or locally-advanced rectal cancer (n = 14) were similar. The mean length of stay was 21 days while the mean BMI of the patients was 24.3 (+/- 5.9) kg/m2. The majority of the patients were either of normal weight (n = 15) or overweight/obese (n = 11). The average length of hospital stay was significantly longer in patients who were underweight compared to those who were of normal weight (F = 6.508, P = 0.006) and those who were overweight and obese (F = 6.508, P = 0.007). CONCLUSION: This study suggests that a lower body mass index preoperatively is associated with a longer length of hospital stay. BMI is not associated with long-term QoL in this patient group. However, further prospective research is required.

PURPOSE: Laparoscopy continues to be increasingly adopted for elective colorectal resections. However, its role in an emergency setting remains controversial. The aim of this study was to compare the outcomes between laparoscopic and open colectomies performed for emergency colorectal conditions. METHODS: A retrospective review of all patients who underwent emergency laparoscopic colectomies for various surgical conditions was performed. These patients were matched for age, gender, surgical diagnosis and type of surgery with patients who underwent emergency open colectomies. RESULTS: Twenty-three emergency laparoscopic colectomies were performed from April 2006 to October 2011 for patients with lower gastrointestinal tract bleeding (6), colonic obstruction (4) and colonic perforation (13). The hand-assisted laparoscopic technique was utilized in 15 cases (65.2%). There were 4 (17.4%) conversions to the open technique. The operative time was longer in the laparoscopic group (175 minutes vs. 145 minutes, P = 0.04), and the duration of hospitalization was shorter in the laparoscopic group (6 days vs. 7 days, P = 0.15). The overall postoperative morbidity rates were similar between the two groups (P = 0.93), with only 3 patients in each group requiring postoperative surgical intensive-care-unit stays or reoperations. There were no mortalities. The cost analysis did not demonstrate any significant differences in the procedural (P = 0.57) and the nonprocedural costs (P = 0.48) between the two groups. CONCLUSION: Emergency laparoscopic colectomy in a carefully-selected patient group is safe. Although the operative times were longer, the postoperative outcomes were comparable to those of the open technique. The laparoscopic group did not incur a higher cost.

Annals of Coloproctology 2013;29(2):55-59
PURPOSE: Managing deep postanal (DPA) sepsis often involves multiple procedures over a long time. An intersphincteric approach allows adequate drainage to be performed while tackling the primary pathology at the same sitting. The aim of our study was to evaluate this novel technique in managing DPA sepsis. METHODS: A retrospective review of all patients who underwent this intersphincteric technique in managing DPA sepsis from February 2008 to October 2010 was performed. All surgeries were performed by the same surgeon. RESULTS: Seventeen patients with a median age of 43 years (range, 32 to 71 years) and comprised of 94.1% (n = 16) males formed the study group. In all patients, an internal opening in the posterior midline with a tract leading to the deep postanal space was identified. This intersphincteric approach operation was adopted as the primary procedure in 12 patients (70.6%) and was successful in 11 (91.7%). In the only failure, the sepsis recurred, and a successful advancement flap procedure was eventually performed. Five other patients (29.4%) underwent this same procedure as a secondary procedure after an initial drainage operation. Only one was successful. In the remaining four patients, one had a recurrent abscess that required drainage while the other three patients had a tract between the internal opening and the intersphincteric incision. They subsequently underwent a drainage procedure with seton insertion and advancement flap procedures. CONCLUSION: Managing DPA space sepsis via an intersphincteric approach is successful in 70.6% of patients. This single-staged technique allows for effective drainage of the sepsis and removal of the primary pathology in the intersphincteric space.

PURPOSE: Mesenteric embolization is an integral part in the management of acute lower gastrointestinal (GI) bleeding. The aim of this study was to highlight our experience after adopting mesenteric embolization in the management of acute lower GI hemorrhage. METHODS: A retrospective review of all cases of mesenteric embolization for acute lower GI bleeding from October 2007 to August 2012 was performed. RESULTS: Twenty-seven patients with a median age of 73 years (range, 31 to 86 years) formed the study group. More than half (n = 16, 59.3%) of the patients were on either antiplatelet and/or anticoagulant therapy. The underlying etiology included diverticular disease (n = 9), neoplasms (n = 5) and postprocedural complications (n = 6). The colon was the most common bleeding site and was seen in 21 patients (left, 10; right, 11). The median hemoglobin prior to the embolization was 8.6 g/dL (6.1 to 12.6 g/dL). A 100% technical success rate with immediate cessation of hemorrhage at the end of the session was achieved. There were three clinical failures (11.1%) in our series. Two patients re-bled, and both underwent a successful repeat embolization. The only patient who developed an infarcted bowel following embolization underwent an emergency operation and died one week later. There were no factors that predicted clinical failure. CONCLUSION: Mesenteric embolization for acute lower GI bleeding can be safely performed and is associated with a high clinical success rate in most patients. A repeat embolization can be considered in selected cases, but postembolization ischemia is associated with bad outcomes.

INTRODUCTIONEmergency gastrectomy has been shown to be associated with poor morbidity and mortality rates. The aims of this study were to review the outcomes of emergency gastrectomy in our institution and to determine any factors that were associated with worse perioperative outcomes.
MATERIALS AND METHODSA retrospective review of all patients who underwent emergency gastrectomy for various indications from October 2003 to April 2009 was performed. All the complications were graded according to the classification proposed by Clavien and group.
RESULTSEighty-fi ve patients, median age 70 (range, 27 to 90 years), underwent emergency gastrectomy. The indications for the surgery included perforation, bleeding and obstruction in 45 (52.9%), 32 (37.6%) and 8 (9.4%) patients, respectively. The majority of the patients (n = 46, 54.1%) had an American Society of Anesthesiologists (ASA) score of 3. Partial or subtotal, and total gastrectomy were performed in 75 (88.2%) and 10 (11.8%) patients, respectively. Malignancy was the underlying pathology in 33 (38.8%) patients. The perioperative mortality rate was 21.2% (n = 18) with another 27 (31.8%) patients having severe complications. Twelve (14.1%) patients had a duodenal stump leak. The independent factors predicting worse perioperative complications included high ASA score and in perforation cases. Other factors such as malignancy, age and extent of surgery were not signifi cantly related. The presence of a duodenal stump leak was the only independent factor predicting mortality.
CONCLUSIONEmergency gastrectomy is associated with dismal morbidity and mortality rates. Patients with high ASA scores and perforations fared worse, and duodenal stump leak increases the risk of mortality.

INTRODUCTIONThe aim of the study was to determine if age at the creation of an ileal pouchanal anastomosis (IPAA) has an impact on the outcomes in patients with ulcerative colitis (UC).
MATERIALS AND METHODSA retrospective review of all patients who underwent IPAA for UC from 1999 to 2011 was performed. Long-term functional outcome was assessed using both the Cleveland Clinic and St Mark's incontinence scores.
RESULTSEighty-nine patients, with a median age of 46 (range, 16 to 71) years, formed the study group. The median duration of disease prior to their pouch surgery was 7 (0.5 to 39) years. There were 57 (64%) patients who were aged ≤50 years old and 32 (36%) who were >50 years old. Fifty-seven (64%) patients developed perioperative complications of which 51 (89.5%) were minor. High ileostomy output (n = 21, 23.6%) and urinary symptoms (n = 13, 14.6%) were the most commonly encountered complications. The older patients were more likely to have an ASA score ≥3 and a longer length of stay. Although there was a higher incidence of complications in the older group of patients, the difference was not statistically significant. There were no significant differences in the incidence of severe complications. Forty-nine (55%) patients completed our questionnaire on the evaluation of their functional outcomes. There were no significant differences in the Cleveland Clinic and St Mark's incontinence scores between the older (n = 19, 38.8%) and younger (n = 30, 61.2%) patients. There were also no significant differences in the frequency of bowel movements during the day or overnight after sleep between the 2 groups.
CONCLUSIONIPAA procedure for patients with UC can be safely performed. Long-term functional outcome is not significantly influenced by the age at which the IPAA was created.
