This pathology is a rare, though increasingly frequent, phenomenon that must be considered in the differential diagnosis when a bowel obstruction without other identifiable cause is encountered, particularly in a patient with history of previous laparoscopy. However, preoperative studies have a poor sensitivity for accurately diagnosing a hernia through the falciform ligament. Failure to consider this etiology may result in delayed operative intervention and increased morbidity and mortality.
For the experienced surgeon, the average operative time for a laparoscopic cholecystectomy is less than 1 hour. There has been no study documenting the causes and results of prolonged (longer than 3 hours) surgery. A retrospective study was done of patients who underwent cholecystectomy between January 2003 and December 2007. A total of 3126 cholecystectomies were done. After excluding patients who had a planned open cholecystectomy and patients who had additional laparoscopic surgeries, we identified 70 patients who had a planned laparoscopic cholecystectomy with operative time exceeding 3 hours. Multivariate stepwise logistic regression was performed analyzing the various factors leading to prolonged surgery. Of the 70 patients, ranging in age from 21 to 92 years (mean, 57 years), most (n = 53) were female. Operative time ranged from 3 hours to 6 hours 40 minutes (mean, 3 hours 37 minutes). Emergency:elective admission ratio was 9:5 and acute cholecystitis (n = 40) was the most common indication. Common characteristics were obesity (n = 44, P = 0.031), intraabdominal adhesions (n = 43, P = 0.004), and previous abdominal surgeries (n = 40, P = 0.002). Intraoperative complications included spillage of stones (n = 6), bile duct injury (n = 3), and bleeding (n = 3). The possibility of prolonged laparoscopic cholecystectomy should be anticipated in patients with obesity and previous abdominal operations. Prolonged surgery increases the risk of complications (bile duct injury, bleeding) and prolongs the postoperative hospital stay.
The prevalence and characteristics of patients with confirmed gastrointestinal stromal tumor (GIST) in a community hospital over a 6-year period are described. Our objective was to communicate our experience managing this rare tumor of the gastrointestinal tract. A retrospective chart review was performed. Patients were selected based on International Classification of Diseases, 9th Revision codes in correlation with their respective confirmational pathology. Patients with a diagnosis of GIST, cells of Cajal tumor, and/or different varieties of gastrointestinal sarcoma were included in this study. These tumors had to have a positive C-kit on immunohistochemistry. Demographic and clinical data were collected from medical records as well as pathology reports. Follow up from attendings’ office records and telephone interviews complemented our data. A total of 61 patients was identified in our institution (averaging 10 patients per year). Females represented 63 per cent of our series. The average ages were 70.2 ± 19.1 years for females and 59.4 ± 13.5 years for males ( P < 0.01). The most common clinical presentation was an intra-abdominal nonobstructing mass followed by an endoscopically detected mass or incidental tumors found during unrelated surgery. Surgical emergencies such as acute abdomen and gastrointestinal bleed were rare. Over half of these tumors were located in the stomach. Other sites were the small intestine, colon, esophagus, and rectal–vaginal septum. Opened surgical resection was performed in two-thirds of treated cases, whereas laparoscopic resection was done in the remainder. Only 18 per cent of these tumors were considered benign, whereas 35 per cent were considered to have some malignant potential and 47 per cent were of undetermined potential. In surgically resected tumors, we found a 42 per cent recurrence rate with a median average time of recurrence of 22 months. Pathologic grading and type of surgery were not predictors of rate and timing of recurrence. However, the disease tended to be more aggressive in white males and age older than 70 years. Imatinib was used mainly in attempts to downstage, control recurrent disease, and make surgery possible. With the improvement of immunohistochemical techniques, the diagnosis of GIST is increasing. Preoperative diagnosis is highly uncertain and dependent on clinical suspicion. Surgical resection is still the main form of curative therapy. Our experience is similar to large-volume centers. GIST, once recognized, can be treated in community hospitals without compromise of their care.
Carcinoid tumors are slow-growing and usually become symptomatic late in the course of the disease. We evaluated our 10-year experience in the management of GI carcinoid tumors. The records of 133 patients with GI carcinoids were reviewed. The rectum was the most common site for carcinoid tumors with an incidence of 30 per cent followed by jejunoileal at 29.3 per cent. Other sites of carcinoid tumors were the appendix (8.3%), colon (8.3%), and duodenum (3.8%). Endoscopy was the most helpful modality in diagnosing GI carcinoids. CT was not helpful in preoperative diagnosis of carcinoid tumor. Fifteen patients died in follow-up with eight deaths related to carcinoid tumors, in the small bowel (6), rectum (1), and colon (1). Overall survival was 68.7 per cent and mortality rate was 19.5 per cent from carcinoid tumors. Most of the deaths occurred in patients with carcinoid syndrome, synchronous malignancy, and malignant carcinoid tumors. The mean disease-free survival was 51 months (range, 15 to 138 months). Screening colonoscopy, in addition to decreasing colorectal adenocarcinoma mortality, is useful in diagnosing carcinoid tumors at an earlier stage and in decreasing mortality from malignant colorectal carcinoid tumors.
Obturator hernia is an exceedingly rare pelvic hernia that occurs primarily in multiparous, elderly thin (>70 years of age) females. Here, we report a case of bilateral obturator hernia in an elderly female with high-grade small bowel obstruction repaired with a novel "cigar roll" technique.
