Required Bowel Resection Research Articles

Risk and outcome of bowel resection in patients with incarcerated groin hernias: retrospective study.

The goal of this retrospective study was to evaluate factors that increase the risk of bowel necrosis and document the outcome of bowel resection in patients with strangulated hernias. We identified 102 patients (60 men, 42 women) who underwent surgical treatment for an incarcerated hernia at the Kartal Education and Research Hospital Emergency Unit between April 1997 and April 2001. Patients in group 1 required intestinal resection (n = 16), and patients in group 2 did not (n = 86). The median age of the patients was 53 years (range 3-96). Demographic and surgical data were obtained from the patients' charts and compared between the two groups. Women required bowel resections more often than men (p < 0.05). Patients older than 65 years and those with femoral or epigastric hernias required resection more often than patients younger than 65 years and those with inguinal, umbilical, or incisional hernias (p < 0.05 for all). Group 1 patients had a longer hospitalization and experienced more overall complications and wound infections than group 2 (p < 0.05 for all). In conclusion, incarcerated hernias are more common in men, but intestinal resection is required more often in women. The risk of intestinal resection is higher for patients with femoral hernias and those older than 65 years. Patients who undergo intestinal resection have a higher overall complication rate related to wound infections but not an increased risk of other complications or mortality.

Complicated umbilical hernias in children.

Umbilical hernia is a common problem in children, particularly in Africans, but complications in these hernias are thought to be rare. In a retrospective study of 47 children presenting for umbilical hernia repair in 14 years, 30 had complications. The complications included acute incarceration 15, recurrent incarceration 10 and spontaneous evisceration 5. Of the 15 with acute incarceration, 2 required bowel resection for gangrene, and an abscess formed in the hernia sac in one. The age of patients with acute incarceration was 2 months-8 years (median 5 years). The 10 with recurrent incarceration were aged 1-3 years (median 3 years). Of the 5 with spontaneous evisceration, one had umbilical sepsis and another intestinal obstruction from intussusception. These patients were aged 3-12 weeks (median 7 weeks). All the complications occurred in hernias that were 1.5 cm or more in diameter. The hernias were repaired using standard methods. Postoperatively, 2 patients developed wound infection. There was no mortality. Though complications of umbilical hernias appear to be rare, there is a need for more active observation of these hernias to identify complications early and treat promptly to avoid morbidity.

A Novel Approach to the Treatment of Gunshot Injuries to the Sacrum

Two patients (a 17-year-old male and a 19-year-old female) sustained single gunshot wounds to the abdomen. Given the nature of their wounds and presumed peritoneal penetration they were taken urgently to the operating room for exploratory laparotomy. Both patients sustained multiple intra-abdominal injuries including gastric and small and large bowel perforations. Given the extensive nature of these injuries both patients required bowel resections. Upon further exploration they were both noted to have significant bleeding from the bony aspect of their sacrum. A surgical hemostat (CoStasis; Cohesion Technologies, Inc., Palo Alto, CA) (4.5-9.0 cm3) was directly applied to the injured area of the sacrum in both cases after standard surgical hemostatic techniques were unsuccessful. After application no further attempts of hemostatic control by standard methods were attempted. In both cases the sacral bleeding ceased without any further surgical intervention. Postoperatively neither patient rebled from the sacral injuries. Penetrating injuries to the sacrum can be life threatening and difficult to control with standard surgical hemostatic techniques. CoStasis, a new surgical hemostat, was effective in obtaining immediate and definitive hemostatic control. Future prospective trials on the use of CoStasis in trauma patients are warranted.

Prospective evaluation of laparoscopic surgery for rectosigmoidal and rectal carcinoma.

This study was designed to examine the short-term results of laparoscopy in the treatment of curative cases of rectosigmoidal and rectal carcinoma. A review was performed of a prospective registry of 70 patients who underwent curative laparoscopic resection for rectosigmoidal and rectal carcinoma between July 1993 and April 2001. Before 1997, only patients with early (Tis or T1) cancers located in the rectosigmoid and upper rectum that required bowel resection were candidates for laparoscopy. In 1997, we expanded the application of laparoscopy to include T2 cancers located anywhere in the rectum. Mesorectal transection was performed at least 5 cm below the tumor for rectosigmoidal and upper rectal lesions, and total mesorectal excision was performed for lower tumors. Primary anastomosis was performed by a double-stapling technique, or a handsewn coloanal anastomosis was performed. Patient demographics and outcomes were recorded prospectively. The median follow-up was 23 months. An anastomosis was performed in 92.9 percent of the operations. Oral intake was started on median postoperative Day 1, and the median length of hospitalization was 8 days. Two patients needed conversion to conventional open surgery. A total of 15 postoperative complications occurred in 13 patients (18.6 percent), including anastomotic leakage in 6 (8.6 percent) and bowel obstruction in 3 (4.3 percent). Reoperation was required in six patients. Two patients developed recurrence of cancer at the anastomotic site. The expected 5-year survival and disease-free survival rates were 100 and 92.1 percent, respectively. The findings of the present study demonstrate the feasibility and safety of laparoscopic surgery for selected patients with rectal carcinoma. Morbidity and mortality rates and oncologic outcome appear to be comparable with conventional surgery.

Case series of acute abdominal surgery in rural Sierra Leone.

In many poor countries of the world the need for surgical treatment of acute abdominal emergencies is largely unmet. In some cases this service is provided by physicians with little postgraduate surgical training, and there is a paucity of published data on the outcomes of this service. This series of sequential cases of acute abdominal surgical emergencies from a hospital in rural Sierra Leone illustrates the causes, outcomes, and challenges in this setting. All patients with an acute abdomen from September 1992 until September 1994 who required surgery were identified by review of theater records, ward books, and patients' notes. Altogether, 173 cases were identified. Operative diagnoses included ectopic pregnancy (n = 43), strangulated hernia (n = 45) 15 of which required bowel resection, appendicitis (n = 15), normal appendix (n = 4), uterine rupture (n = 9), perforated ulcer (n = 8), tubal or pelvic abscess (n = 7), volvulus (n = 6), and others. Ninety percent survived to discharge after a median postoperative stay of 9.2 days (range 7-127 days). Of the 18 deaths, 83% occurred during the first 3 days. Factors associated with poor outcome were ileal perforation due to typhoid fever and resection of bowel after a strangulated hernia. These results show that acute abdominal surgery can be done at the district level in poor countries using limited facilities by staff without extensive surgical training. The outcomes are comparable to those from larger centers.

The morbidity and mortality of right hemicolectomy for complicated intussusception in infants

Infants with intussusception in tropical Africa frequently present late. Intestinal resection for gangrene or perforation may warrant a right hemicolectomy. Over a period of 11 year, 15 (45.5%) of 33 infants with intussusception required bowel resection, 10 of which were right hemicolectomies. The age range of those who had right hemicolectomy was 3-9 months (median 6 months) and duration of symptoms 3-8 days (median 6 days). In addition to features of intussusception, seven (78%) infants were dehydrated and one was anaemic. Six (67%) of 9 infants developed procedure related complications postoperatively. Four (44%) had anastomotic dehiscence, associated with abdominal wound dehiscence in 2. In 3 of the patients, the anastomosis leaked again following repeat resection and anastomosis, necessitating relaparotomy and stoma formation. One (11%) patient each had wound infection and prolonged ileus respectively. Six (67%) patients died, including the 4 who had anastomotic dehiscence. The cause of death was overwhelming infection in 4 patients and aspiration of vomitus in two patients. Recommendations are made to minimize morbidity and mortality in these infants.

High multidrug resistance (P-glycoprotein 170) expression in inflammatory bowel disease patients who fail medical therapy

Background & Aims: The multidrug resistance (MDR) gene codes for a drug efflux pump P-glycoprotein 170 (Pgp-170) expressed on the surface of lymphocytes and intestinal epithelial cells. Inflammatory bowel disease (IBD) poorly responsive to medical therapy may relate to MDR expression because glucocorticoids are known Pgp-170 substrates. Methods: Using flow cytometry, we measured peripheral blood lymphocyte (PBL) MDR in 153 IBD patients and 50 healthy volunteers, and assessed the relationship between PBL, mucosal intraepithelial lymphocyte (IEL), and mucosal epithelial cell (EC) MDR expression in a further 20 IBD patients and 19 controls. Results: Compared with controls, PBL MDR was significantly elevated in patients with Crohn's disease who required bowel resection for failed medical therapy (mean ± SEM, 26.7 ± 2.8 vs. 11.9 ± 1.0; P <0.0001) and patients with ulcerative colitis who required proctocolectomy for failed medical therapy (20.3 ± 2.5 vs. 11.9 ± 1.0; P = 0.001). PBL MDR remained stable over time and was not influenced by disease activity or glucocorticoid therapy. Both PBL and mucosal MDR expression appeared independent of disease activity, and there was a significant correlation between PBL MDR expression and both IEL expression ( r = 0.92; P < 0.0001) and EC expression ( r = 0.54; P < 0.001). Conclusions: PBL and mucosal MDR expression may play an important role in determining the response of IBD patients to glucocorticoid therapy. GASTROENTEROLOGY 2000;118:279-288

Utility of preoperative fiberoptic flexible sigmoidoscopy in the evaluation of patients with suspected gynecologic malignancy

Background: Fiberoptic flexible sigmoidoscopy (FFS) is routinely requested preoperatively as part of evaluation of pelvic masses to exclude colonic involvement by the tumor or concurrent colonic neoplasm. The aim of our study was to evaluate the utility of preoperative FFS in patients with suspected gynecologic malignancy. Methods: FFS, performed using a 60 cm sigmoidoscope, evaluated (1) presence of bowel involvement by the tumor, (2) extrinsic compression by the tumor, and (3) presence of colonic neoplasms. FFS findings were correlated with surgical findings. Results: A total of 107 women underwent preoperative FFS and subsequent surgery. Eleven patients (11%) had lower gastrointestinal symptoms. At surgery, 63% of pelvic tumors were malignant and 37% were benign. The most common abnormality at FFS was colonic polyps in 23 patients (21%). Colonic adenomas were found in 11 patients (10%). Extrinsic compression by the tumor without mucosal abnormalities was seen in 15 patients (14%). The most common intraoperative finding was tumor adhering to the bowel in 18 patients requiring dissection, but only 1 patient required bowel resection. Eight of these 18 patients had preoperative lower gastrointestinal symptoms. All 15 patients with extrinsic compression at FFS had tumor adhering to the bowel. Conclusions: Pelvic masses cause extrinsic compression at FFS in 14% of patients. This is suggestive of tumor adherent to the bowel at surgery. However, bowel resection is rarely required because of tumor involvement. Most patients with bowel adherence by tumor have lower gastrointestinal symptoms. Colonic adenomas are found in one tenth of patients, mostly in patients older than 50 years of age. Preoperative FFS does not change the surgical management of pelvic tumors. Screening FFS is indicated in all patients with pelvic tumors over age 50, as in persons with average risk, but is otherwise unnecessary in evaluation of pelvic masses.

Vaginal Evisceration

Vaginal evisceration is a rare complication of an enterocele. We report a patient who presented with spontaneous evisceration per vagina secondary to erosion through an attenuated vaginal wall. This resulted in a strangulated hernia requiring bowel resection and enterocele repair. This patient is discussed as are the risk factors and management options for patients with vaginal evisceration.

Impact of intestinal lengthening on the nutritional outcome for children with short bowel syndrome

Survival among children with short bowel syndrome has increased with the use of supportive nutritional techniques including parenteral and enteral nutrition. Further improvement in outcome has been sought by using intestinal lengthening procedures to lengthen the bowel, improve intestinal motility, initiate a progressive increase in intestinal mucosal mass, and thereby improve tolerance to enteral nutrition. The authors examine the growth parameters and the tolerance to enteral nutrition in children with refractory short bowel syndrome before and after intestinal lengthening procedures. For seven children, the percentage of calories from enteral nutrition, the medical and surgical complications, and the number of days in the hospital (1 year before and 2 years after the lengthening procedure) were evaluated. The mean birth weight was 1,991 g (range, 1,198 to 3,096 g). The initial diagnoses requiring bowel resection included necrotizing enterocolitis, multiple small bowel atresias, gastroschisis with midgut volvulus, cloacal exstrophy, and long-segment Hirschsprung's disease. The mean length of the residual small bowel was 49 cm (range, 6 to 92 cm). All but one child had surgical resection of the ileocecal valve. The percentage of enteral nutrition calories significantly increased by 9 months after the procedure ( P < .008, analysis of variance). Only one child has been completely weaned from parenteral nutrition. All children's growth parameters have been maintained or improved (weight/age, height/age, and weight/height). Few major medical and surgical complications have been observed. Central venous catheter infection has been the most common medical complication. The mean number of hospitalization days decreased during the second year after the lengthening procedure. The authors conclude that the intestinal lengthening procedure enhances the tolerance for enteral nutrition, improves the nutritional status, and decreases the need for hospitalization. The procedure should be considered for children with refractory short bowel syndrome who require prolonged parenteral nutrition.

Water-soluble contrast material has no therapeutic effect on postoperative small-bowel obstruction: Results of a prospective, randomized clinical trial

Hyperosmotic water-soluble contrast materials have been fo und to be helpful diagnostic tools in postoperative small-bowel obstruction (POSBO); however, their therapeutic value remains controversial. A prospective, randomized clinical study was conducted to examine the use of meglumine ioxitalamate as a supplement to the standard conservative treatment of POSBO. Patients with POSBO (n = 50) suitable for a conservative approach were randomized to receive standard conservative treatment with (n = 25) or without (n = 25) the addition of 100 mL of meglumine ioxitalamate via the nasogastric tube (patients with diffuse carcinomatosis and early POSBO were excluded). Both groups were compared for resolution of obstruction, need for surgical relief of obstruction, and complications. Seven (14%) patients required surgery: 3 in the contrast material group and 4 in the control group (P = not significant [NA]. Resolution of symptoms was achieved in nonsurgical patients within an average of 25.7 hours in the contrast material group and 28.7 hours in the control group (P = NS). There was no mortality in this study. In 2 (4%) patients (1 in each group), strangulated bowel was found during surgery, but only the 1 (2%) patient in the contrast material group required bowel resection. No difference was found in the length of hospital stay or rate of complications. There were no complications that could be attributed to the use of the contrast material itself. Although water-soluble contrast material is a safe and useful diagnostic tool, it offers no advantage as a supplement to the usual conservative treatment of POSBO.

Adhesive small-bowel obstruction in children

Seventy-one episodes of adhesive small-bowel obstruction (ASBO) in 57 children were reviewed to define the relationship of treatment methods to clinical conditions and to examine the place of conservative treatment. Thirteen children received urgent operations on the day of admission because of signs of suspected strangulation or complete obstruction. The remaining 58 episodes underwent initial conservative treatment, which was successful in 35 while 23 required subsequent surgical intervention, an overall incidence of operation in 36 of the 71 (50.7%) episodes of ASBO. Seven episodes required bowel resection, strangulation was found in 3 (4.2%), and mortality occurred in 1 (1.7%) due to delayed operation. Patients with more than one previous successfully treated occurrence of ASBO were significantly more likely to respond to conservative treatment (71.4% vs. 54.4%, P <0.05). Those patients who had undergone laparotomies twice or more before the episode were more likely to be successfully treated by conservative treatment than those who underwent laparotomy only once before (80% vs. 52.4%, P <0.01). Whether or not the treatment of the previous occurrences of ASBO was surgical, we found that the initial treatment of any further episode could be conservative except when evidence of a complete or strangulated bowel obstruction developed.

Segmental small-bowel volvulus not associated with malrotation in childhood

During the last 15 years, 38 children with volvulus of the intestine were treated in our hospital. Twenty-eight (73.7%) had midgut volvulus with malrotation, including 2 cases of isolated incomplete rotation of the duodenum; 10 (26.3%) had segmental volvulus of the ileum without malrotation, 3 of them assumed to be secondary to a duplication cyst, retroperitoneal band, or meconium plug; in the remaining 7 no causative abnormality was found. Nine were neonates, 8 of whom presented within the first 48 h after birth. The remaining patient was a 5-year-old girl. In all cases the correct preoperative diagnosis was not made, but obstruction or coiling of the distal ileum was demonstrated by contrast enemas in 5. Ischemic changes of the affected bowel were seen in 90% of the cases without malrotation. This contrasts with an 18% incidence in the cases with malrotation, and indicates the necessity of early diagnosis and operation. All patients required bowel resection and 2 died of sepsis after the operation, however, none suffered from short-bowel syndrome.

Case Report. Small bowel herniation following laparoscopy-assisted vaginal hysterectomy: A difficult differential diagnosis

SummaryA small bowel obstruction, thought to be secondary to prior surgery, revealed itself to be an incarcerated umbilical hernia requiring bowel resection.

Eosinophils within the healthy or inflamed human intestine produce substance P and vasoactive intestinal peptide

The purpose of this study was to show if inflammatory cells within healthy or diseased human intestinal mucosa produce some regulatory neuropeptides. First, inflammatory cells were isolated from the intestinal lamina propria of 11 patients with ulcerative colitis or Crohn's disease. Also collected were cells from anatomically normal intestine derived from five patients requiring bowel resection for diseases not related to inflammatory bowel disease. Extracts of these isolated cells contained authentic substance P (SP) and vasoactive intestinal peptide (VIP) as shown by RIA and their elution profiles on HPLC. Immunostaining of cells from nine of 13 additional patients localized immunoreactive SP and VIP to secretory granules within most mucosal eosinophils. No other cell types stained positive. Messenger RNA encoding SP and VIP was localized to lamina propria eosinophils by in situ hybridization. Mucosa inflammatory cells, from eight of nine more patients, cultured in vitro, released detectable amounts of VIP, but not SP. It is concluded that intestinal eosinophils produce SP and VIP. Since the eosinophils store and release more VIP than SP, it is possible that VIP is the preferred secretory product.

Pneumatic reduction of intussusception: 5-year experience.

Pneumatic reduction of 246 intussusceptions was attempted in 219 patients over a 5-year period. The mean age of the patients was 15.4 months. Successful reduction was achieved in 199 cases (80.9%). Bowel perforation occurred in seven cases (2.8%), requiring needle decompression of tension pneumoperitoneum in one case. Recurrence of intussusception occurred in 27 cases (11%). The mean fluoroscopy time was 3.5 minutes +/- 0.2 in successful reductions and 9.3 minutes +/- 0.9 in failed reductions (P less than .001). Logistic regression analysis helped identify four independent predictors of failure, as follows: (a) ileoileocolic intussusception (P less than .001), (b) long duration of symptoms (P less than .001), (c) rectal bleeding (P less than .01), and (d) failed reduction with barium at another institution (P less than .05). Predictors of bowel perforation were a younger age (P less than .05) and long duration of symptoms (P less than .05). Surgery was performed in 48 cases (19.5%), 16 of which required bowel resection. Transmural necrosis of bowel wall was found in nine specimens. The most important predictor of outcome in this series was a long duration of symptoms. Pneumatic reduction is a useful substitute for barium in the management of pediatric intussusception.

Perforated pseudomembranous colitis in the breast-fed infant

Pseudomembranous colitis (PMC) is uncommon in the infant and complications requiring surgical intervention are rare. All prior cases have involved the direct administration of antibiotics to the child. A 2-month-old girl required bowel resection for perforation of a thickened and inflamed left colon. Findings were consistent with PMC and the stool was Clostridium difficile toxin positive. The patient was treated with vancomycin and did well. The patient's mother later admitted to self-administration of ciprofloxacin while breast-feeding her infant. Oral doses of this drug are concentrated in breast milk at levels higher than serum. Antibiotics derived from breast milk can cause complicated PMC in the infant. A directed history can establish an early diagnosis and help distinguish PMC from other more common infantile enterocolitides.

Operative laparoscopy for the treatment of ovarian remnant syndrome

To present the technique and assess the efficacy of operative laparoscopy to manage ovarian remnant syndrome. Observational with a follow-up of 6 to 32 months. Private subspecialty practice with a large referral base. Thirteen women, 9 with previous bilateral salpingo-oophorectomy and 4 with previous unilateral salpingo-oophorectomy and pain on the ipsilateral side. Multipuncture advanced operative laparoscopy. Patient pain relief was assessed through return examinations, telephone interviews, or contact with referring physicians. Nine patients reported complete pain relief. One reported incomplete but satisfactory pain relief. Two required bowel resection by laparotomy to obtain pain relief, and one, despite subsequent laparotomy, had persistent pain. No intraoperative or postoperative complications were noted. Laparoscopy can be effective in managing ovarian remnant syndrome when performed by an experienced laparoscopist.

Value of sonography including color Doppler in the diagnosis and management of long standing intussusception.

15 cases of intussusception with presenting symptoms of more than 24 h duration were studied by sonography and Doppler. The aim of the study was to determine the validity of the sonographic criteria of peritonitis and bowel ischaemia in order to reduce the risk of colonic perforation and to increase confidence in achieving a successful hydrostatic reduction. The results were reviewed retrospectively and cases divided into 2 groups. Cases in group 1 were reducible by barium enema while those in group 2 required surgical intervention. Sonographic features of peritonitis were absent in all cases of group 1 and 3 cases of group 2. These 3 cases were reduced manually at surgery while the other 5 cases in group 2 with positive features of peritonitis required bowel resection. Blood flow was documented by colour flow Doppler in all cases except the 3 cases with gangrenous bowel in group 2. When sonographic features of peritonitis and loss of blood flow to the intussusception are present in late intussusception, surgical intervention is required. On the other hand, enema reduction should be pursued when such features are absent.

Postoperative Intussuception: Increasing Frequency or Increasing Awareness?

Postoperative intussusception in children is a rare but well recognized phenomenon. The diagnosis is often delayed due to the protean manifestations of the disorder (ileus, distention, and nausea and vomiting) which, when encountered shortly after an abdominal operation, usually result in a low index of suspicion because they are common after laparotomy. Experience with two cases of postoperative intussusception within 24 hours heightened our index of suspicion. Review of our records indicated we had diagnosed and treated postoperative intussusception in 14 children during the preceding 4 years. Patient ages ranged from 4 months to 12 years (mean 39 months, median 20 months), and symptoms appeared on postoperative days 3 to 36 (mean 10 days, median 6 days). Initial operations included excision of a retroperitoneal or abdominal tumor (five cases), Nissen fundoplication and gastrostomy (three), ileal resection (two), Ladd procedure (one), Duhamel operation (one), and operative reduction of ileocolic intussusception (the two most recent cases). Eleven patients had appendectomy (five by the inversion technique), and three had placement of a transgastric small bowel feeding tube. Nine children had had either barium enema or upper gastrointestinal studies because of the postoperative suspicion of obstruction; one patient had both. Diagnostic studies were not done in four patients. Operative reduction was successful in all but one child, who required bowel resection.
