Outcome of surgery for colovesical and colovaginal fistulas of diverticular origin in 40 patients.

INTRODUCTION: According to literature, colonic resection with a primary anastomosis and no defunctioning ileostomy is a safe treatment for colovesical or colovaginal fistula of diverticular origin. This study investigates the outcome of surgery for this patient group in a regional hospital. METHODS: Patients were obtained from a prospective database in the period 2004-2011. Several variables were investigated for their relation with surgical outcome. RESULTS: A colovesical (n = 35) or colovaginal (n = 5) fistula was diagnosed in 18 men and 22 women. The mean age was 69 years (range, 45-90). A rectosigmoid resection with primary anastomosis was performed in 32 patients. Fourteen patients received a defunctioning ileostomy. Eight patients were treated with a Hartmann procedure. Overall 30-day treatment-related morbidity and mortality was 48 and 8 %, respectively. Major morbidity, because of anastomotic leakage, was mainly observed in the primary anastomosis group without a defunctioning ileostomy. Morbidity and mortality were associated with high body mass index, diabetes, use of corticosteroids, and American Society of Anesthesiologists classification, though not significantly. CONCLUSIONS: One should be liberal in the use of a defunctioning ileostomy in case of a primary anastomosis after colonic resection for a diverticular fistula, in order to prevent high morbidity rates due to anastomotic leakage.

Is biliopancreatic diversion with duodenal switch a solution for patients after laparoscopic gastric banding failure?

BACKGROUND: Weight loss failure after laparoscopic gastric banding (LAGB) can occur in ≤ 25% of patients. Conversion to a malabsorptive procedure might provide more durable weight loss. The present study evaluated biliopancreatic diversion with duodenal switch (BPD/DS) after LAGB failure with a 3-year follow-up period. METHODS: A total of 35 patients underwent BPD/DS after LAGB failure and were prospectively analyzed using a multidisciplinary approach. Weight indexes, co-morbidities, complications, morbidity/mortality, and nutritional status were analyzed. RESULTS: Excess weight decreased from 91% (134 kg, body mass index 48 kg/m(2)) to 75% (124 kg, body mass index 44 kg/m(2)) after LAGB failure and decreased further to 40% (100 kg, body mass index 35 kg/m(2)) after BPD/DS. The mean percentage of excess weight loss was 55% after LAGB and BPD/DS together and 48% after BPD/DS alone. The incidence of co-morbidities, such as diabetes, sleep apnea, hypertension, hyperlipidemia, joint problems, and chronic obstructive pulmonary disease was reduced after BPD/DS. Nutritional deficiencies were already present after LAGB failure (e.g., iron, ferritin, vitamins B(12), B(6), A, D, and E, albumin, and calcium) and either increased (folic acid, potassium, and vitamin B(12)), remained stable (iron, ferritin, vitamin A), or decreased after BPD/DS (albumin and vitamins B(6) and E). CONCLUSION: BPD/DS provided substantial weight loss after LAGB failure and reduced the incidence of obesity-related co-morbidities during a 3-year period. Long-term nutritional follow-up is advocated for all patients after malabsorptive BPD/DS.

Outcome of 232 morbidly obese patients treated with laparoscopic adjustable gastric banding between 1995-2003.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is widely used for the treatment of morbidly obese patients. We prospectively evaluated the effect of LAGB since 1995. METHODS: Between March 1995 and August 2003, 232 morbidly obese patients underwent LAGB. The pars flaccida technique was used in the majority of the patients. Data were prospectively collected. RESULTS: The median age was 35 years and 93% were female. Initial median body weight was 129 kg with a median BMI of 46. After 5 years of follow-up, median BMI decreased to 36 and the median body weight decreased to 98 kg. Median excess weight loss was 37% after 1 year, 42% after 3 years and 42% after 5 years of follow-up. Late postoperative complications were pouch dilatation (n = 33), port revision (n = 19), erosion (n = 4) and necrosis (n = 1). CONCLUSION: LAGB is a safe and successful treatment for patients with morbid obesity. Maximal weight reduction is achieved within 12 months and remains stable up to at least 5 years. These results suggest that LAGB could have a positive outcome on morbid obesity-associated morbidity and overall life expectancy.

[Acute abdominal symptoms in patients with a gastric band]. / Acute buikklachten bij patiënten met een maagband.

Three women aged 32, 35 and 37 years, respectively, presented with upper abdominal symptoms such as pain, nausea and vomiting. Their history revealed that an adjustable silicone gastric band had been implanted for the treatment of obesity one, four and seven years previously. Their symptoms were not immediately recognised as being possible complications of the gastric band and this caused treatment delay. In the first two patients ischaemic lesions were found at laparotomy. Their surgical treatment was successful. The third patient, however, was referred to the surgeon who had placed the gastric band, but she died in the mean time. Lack of recognition of symptoms caused by gastric banding and delay in diagnostic and therapeutic intervention may lead to very serious complications, or even death. Good diagnostic imaging and prompt therapeutic intervention can prevent the progression from herniation of the stomach through the silicone gastric band to irreversible ischaemia and eventually necrosis and perforation.

[Splenectomy in a large general hospital: often caused by iatrogenic injury, often causing multiple complications; poor adherence to post-operative guidelines for vaccination and prophylaxis]. / Splenectomie in een groot algemeen ziekenhuis: vaak iatrogeen letsel als oorzaak, veel complicaties tot gevolg; naleving postoperatieve richtlijnen voor vaccinatie en profylaxe gebrekkig.

OBJECTIVE: To assess the indications, complications and mortality associated with splenectomy in a large general hospital, and to evaluate adherence to guidelines for postoperative vaccination and prophylactic antibiotics. DESIGN: Retrospective, descriptive. METHOD: Data were collected on 106 patients who underwent splenectomy between 1999 and 2004. Indications for surgery, complications, duration of hospitalisation, and vaccination status were investigated retrospectively. Patients were contacted by telephone for a structured interview regarding vaccination and antibiotic prophylaxis. RESULTS: Of the 95 patients with sufficient data for analysis, 41 underwent elective surgery and 54 underwent non-elective surgery, including 37 who required splenectomy due to iatrogenic injury. Posteroperative complications arose in 45 patients, including 23 who developed serious complications. 10 patients died due to complications, including 7 who died within one month after the procedure. Vaccination coverage for the entire group was 58%. CONCLUSION: In this large general hospital, splenectomy was often performed due to iatrogenic injury and was associated with a relatively high complication rate. Adherence to guidelines on vaccination and prophylactic antibiotics could be improved.

Parotid metastasis from a gastroesophageal carcinoma: report of a case.

Carcinomas of the lower esophagus, gastroesophageal junction or stomach rarely metastasize to the cervical lymph nodes. Furthermore, the parotid gland is an even more unusual site of metastasis from a carcinoma located at these sites. We describe the case of a 45-year-old male patient who was diagnosed 2 months after transhiatal gastroesophagectomy for a primary gastric adenocarcinoma with metastasis in the left parotid gland. In the literature we have only found one other case report.

Satisfaction and complications in post-bariatric surgery abdominoplasty patients.

BACKGROUND: Bariatric surgery is an expanding field, with subsequent increases in the number of patients seeking additional corrective procedures including abdominoplasty. Complication rates and body image changes may be different from the general population seeking corrective procedures. METHODS: We performed a retrospective study by questionnaire and chart-based review of the patients who underwent laparoscopic adjustable gastric banding (LAGB) and abdominoplasty at our hospital between 1995 and 2004. Outcome variables included minor and major complications and satisfaction with body image and functional outcome. RESULTS: Patients who returned the completed questionnaire were included in the study (n = 25). The most prevalent complications were seroma formation (25%) and wound infections requiring antibiotics (13%). Hygiene, mobility and general functional capacity improved in 68%, 72%, and 80%, respectively. Body satisfaction and body mass index (BMI) did not markedly change, while self-efficacy improved after abdominoplasty. CONCLUSION: Abdominoplasty is a safe and effective method of body contour correction in patients with massive weight loss after bariatric surgery. However, a BMI as close to the ideal as possible is necessary for the complication rate to approach that of the general population undergoing abdominoplasty. Patients should be made aware of the difference in body image changes after abdominoplasty as compared to post-LAGB, as well as the trend towards an unchanged BMI.

Carcinoma of the sigmoid presenting as a right inguinal hernia.

We present the case of a 44-year-old man who presented with nausea, vomiting and acute pain in the right groin. On physical examination an irreducible mass was palpated in the right inguinal region. Ultrasound suggested an inguinal hernia sac with bowel contents. Subsequent right inguinal exploration revealed only unspecified necrotizing tissue, but no hernia sac or bowel contents were identified. Two days later laparotomy was required since the inguinal wound produced faecal discharge. The sigmoid appeared to be necrotic and perforated, and was subsequently resected. Histology revealed a perforated adenocarcinoma without lymph node involvement. Incarcerated inguinal hernias containing an adenocarcinoma of the colon are rare, but should be considered in patients presenting with an irreducible palpable mass in the inguinal region. Moreover, a carcinoma of the sigmoid may invade the right inguinal region. An intestinal perforation to skin-level in this population is even rarer and is associated with high morbidity and mortality rates.

[Small-bowel obstruction as the expression of hereditary non-polyposis colorectal carcinoma]. / Dunnedarmobstructie als uiting van heriditair non-polyposiscolorectaal carcinoom.

A 25-year-old man underwent periodic coloscopy due to the occurrence of colon carcinoma in the family. At the age of 41, a mutation in the MSH2-gene was detected. More than a year after resection of the sigmoid for recurrent diverticulitis, he developed ileus in the small intestine; in the resected specimen of a non-viable portion of small intestine an adenocarcinoma was found. One year after a wide repeat resection, the patient is doing well. The prevalence of small-bowel tumours in patients with hereditary non-polyposis colorectal carcinoma (HNPCC) is relatively high, but low in absolute terms. There are no good options for screening patients for small-bowel tumours. HNPCC patients presenting with complaints that could be due to obstruction should undergo gastroduodenoscopy, coloscopy or, if these yield negative results, wireless capsule endoscopy to reveal obstruction. In case of iron deficiency anaemia or symptoms that cannot immediately be related to an obstruction, one should be careful with a diagnostic laparotomy. In any other case the threshold for a diagnostic laparotomy should be quite low.

Mannitol-induced acute renal failure.

Mannitol is widely used because of its osmotic diuretic action and its presumed antioxidant properties. In pre-existent renal dysfunction, however, mannitol may accumulate leading to potentially deleterious effects. We describe a 71-year-old woman with moderate chronic renal failure due to diabetic nephropathy who developed acute anuric renal failure after mannitol administration for post-traumatic reflex sympathetic dystrophy. After haemodialysis symptoms of acute renal failure rapidly disappeared with recovery of pre-existent renal function. Daily measurement of the osmolal gap as a simple and accurate way of monitoring patients receiving mannitol infusion is emphasized. A rapid increase in the osmolar gap should prompt adjustment of the dose or even discontinuation of mannitol, especially in the case of pre-existent risk factors.

[Expectant management concerning the breast in 5 patients with occult breast carcinoma]. / Expectatief beleid ten aanzien van de mamma bij 5 patiënten met occult mammacarcinoom.

Five women, between 53 and 78 years old, had axillary lymph node disseminations without a primary breast tumour being found at clinical and radiological investigations. There is much uncertainty about the treatment to be applied in such cases. The patients' breasts were left untreated. One patient had a manifest breast tumour after 6 months' follow-up. The other four patients did not show any sign of a primary tumour after a median follow-up of 26 months (21-96). An expectative policy has already found support in medical literature. The axilla should preferably be treated with axillary lymph node dissection.

Unstable Colles' fractures in elderly patients. A randomised trial of external fixation for redisplacement.

We report the results of a prospective randomised controlled trial of the management of 101 Colles' fractures in patients over the age of 55 years. Within two weeks of initial reduction 43 fractures had displaced with either more than 10 degrees dorsal angulation or more than 5 mm radial shortening. These patients were randomly divided into two groups: 21 were remanipulated and held by an external fixator; in the control group of 22 patients, the redisplacement was accepted and conservative treatment was continued. Patients treated with external fixation had a good anatomical result, but their function was no better than that of the control group. We found no correlation between final anatomical and functional outcome, and concluded that the severity of the original soft-tissue injury and its complications are the major determinants of functional end result.

Enterostomy as an adjunct to treatment of intra-abdominal sepsis.

In 60 patients a small bowel enterostomy was constructed as part of the treatment of various intra-abdominal infectious and obstructive conditions. Eleven patients (18 per cent) died in the immediate postoperative period from continuing sepsis. In one patient closure of the stoma was not considered because of disseminated malignancy. In the remaining 48 patients continuity of the gut was subsequently restored. In 22 patients (46 per cent) complications occurred, 12 (25 per cent) of which were intra-abdominal septic complications. The occurrence of intra-abdominal complications was found to be linked to premature (i.e. within 3 months) closure of the stoma. Reasons for premature closure were stomal difficulties and prerenal azotaemia. Stomal closure was attended by a 10 per cent mortality rate.

Conservative treatment of fractures of the acetabulum. Results after longtime follow-up.

In a retrospective study the long-term results of conservative treatment of acetabular fractures has been evaluated. From 1967 through 1983, 79 patients with 81 fractures of the acetabulum were treated. The fractures were classified according to Judet and Letournel (1). Out of these 79 patients 83% had multiple injuries. The mean Injury Severity Score was 34 (9-75). Follow-up examination was performed in 55 patients. Partial avascular necrosis of the femoral head appeared in 11%. Fractures without dislocation had all a good prognosis. Fractures with dislocation, where the anterior column was involved, had a relative similar prognosis. In 79% of patients, where the dorsal column or roof of the acetabulum was involved, had a moderate or bad result. We conclude that no optimal result can be expected, when in dorsal column or acetabular roof fractures the reposition achieved by conservative treatment is insufficient. In these cases operative reposition and fixation should be considered.

The carcinoid of the intestine.

From 1956 to 1985, 38 patients with a carcinoid of the intestine were treated. Tumours originating from the duodenum, ileum and colon had the worst prognosis. Fourteen out of 15 patients showed lymph-node metastases, and eight liver secondaries. Metastatic spread was rare (9%) if the primary tumour was small or an incidental finding (appendix). Even with metastatic spread there may be a longer survival due to the slow growth pattern of carcinoid metastases, which often become manifest several years after resection of the primary tumour. Metachronous liver metastases should be considered for surgical resection. Three of the 38 patients suffered from a carcinoid syndrome.

Anastomotic insufficiency in small bowel surgery--incidence and treatment.

In the period 1977-1981 234 small bowel anastomoses were constructed in 143 patients. Eight anastomoses showed leakage (3.4%) and from nine anastomoses a fistula developed (3.8%): a total rate of disturbed healing of small bowel anastomoses (7.3%). In the presence of intra-abdominal infection this rate was 14.8%, in the absence of infection 0.8%. The results of treatment with oversewing and with resection and immediate anastomosis were disappointing. Better results were obtained by dismantling of the anastomosis, establishment of a split-enterostomy and reestablishment of continuity in a second stage. Mortality was 3/17 (18%). The literature is reviewed.

Solubility of tissue hydroxyproline in experimental intestinal anastomoses.

Salt and acid solubility of collagen are thought to reflect its degree of crosslinking. In order to examine postoperative changes in crosslinking of intestinal collagen, which are of importance to the stability of the intestinal wall, we have investigated the solubility of hydroxyproline in rabbit ileum and colon, both in unwounded intestine and after construction of an anastomosis. Solubility in salt and dilute acid was increased by a sonication procedure. This way, 9% of total hydroxyproline in the unwounded colonic wall was salt soluble and 65% acid soluble. A similar distribution was observed in ileum. Three days after operation the salt-soluble fraction was significantly elevated in samples from the anastomotic area. In colon, this increase also persisted 7 days postoperatively. Comparison of anastomotic samples collected 3 and 7 days after surgery shows a significant decrease in the acid-soluble and a significant increase in the solid fraction. This phenomenon occurs both in ileum and colon. These results indicate that during the first days after operation the integrity of the intestinal wall is weakened not only by a loss of collagen, but also by a changed solubility of the remaining collagen.

Histological features of wound repair: a comparison between experimental ileal and colonic anastomoses.

Various histological parameters of wound repair have been studied in intestinal anastomoses in the rabbit in order to compare the healing processes in ileum and colon. The sequentional appearance of granulocytes, macrophages and fibroblasts has been studied from 3 h to 7 days after operation. Also, degree of necrosis, formation of capillaries and mucosal repair were analysed semi-quantitatively. Significant differences were observed between ileal and colonic anastomoses with respect to occurrence of granulocytes, necrosis and mucosal repair, particularly 7 days after operation. At that time, granulocytes and necrosis were virtually absent from ileal anastomoses, while mucosal integrity was restored in the majority of cases examined. In contrast, granulocytes and necrosis were still abundantly present in colonic anastomoses and mucosal repair was poor. These results support biochemical evidence that wounds in the ileum heal more rapidly than wounds in the colon. Possibly, the sustained presence of granulocytes, which are a potential source of collagenase activity, is important in this respect. Investigation of the same features of intestinal wound healing in rabbits with peritonitis induced by infection showed similar results and no differences were found between infected and non-infected animals.
