Post pancreaticoduodenectomy haemorrhage: outcome prediction based on new ISGPS Clinical severity grading

OBJECTIVE & BACKGROUND DATA: Mortality following pancreatoduodenectomy (PD) has fallen below 5%, yet morbidity remains between 30 and 50%. Major haemorrhage following PD makes a significant contribution to this ongoing morbidity and mortality. The aim of the present study was to validate the new International Study Group of Pancreatic Surgery (ISGPS) Clinical grading system in predicting the outcome of post pancreaticoduodenectomy haemorrhage (PPH).

MATERIAL AND METHODS

Between January 1998 and December 2007 a total of 458 patients who underwent Whipple's pancreaticoduodenectomy in our department were analysed with regard to haemorrhagic complications. The onset, location and severity of haemorrhage were classified according to the new criteria developed by an ISGPS. Risk factors for haemorrhage, management and outcome were analysed.

RESULTS

Severe PPH occurred in 14 patients (3.1%). Early haemorrhage (<24 hours) was recorded in five (36%) patients, and late haemorrhage (>24 hours) in nine (64%) patients. As per Clinical grading of ISGPS 7 (50%) belongs to Grade C and 7 (50%) belongs to Grade B. Haemostasis was attempted by surgery in 10 (71%) patients; angioembolisation was successful in two (14%) and endotherapy in one (7%) patient. The overall mortality is 29%(n=4). Age >60 years (p=0.02), sentinel bleeding (p=0.04), pancreatic leak (p=0.04) and ISGPS Clinical grade C (p=0.02) were associated with increased mortality.

CONCLUSION

Early haemorrhage was mostly managed surgically with better outcome when endoscopy is not feasible. Late haemorrhage is associated with high mortality due to pancreatic leak and sepsis. ISGPS Clinical grading of PPH is useful in predicting the outcome.

Role of retrograde dilatation in the management of pharyngo-esophageal corrosive strictures

Pharyngo-esophageal corrosive stricture is a complex clinical scenario. If an esophageal opening cannot be found orally through endoscopy, a retrograde approach with a mini-laparotomy and gastrostomy should be attempted. This study primarily aimed at defining the role of preoperative retrograde dilatation of pharyngo-esophageal corrosive strictures. A retrospective analysis of 51 cases of pharyngo-esophageal corrosive strictures identified between 1997-2005 was performed. The demographic details were analyzed. The details of the injury to the pharynx either in isolation or in combination were noted and the management details were recorded. In 21 patients preoperative retrograde dilatation was considered and the technique was successful in 14 (Group I). In seven the technique failed (Group II) and these patients underwent transhiatal resection and gastric pull-through and/or retrosternal pharyngocoloplasty. In Group I patients the postoperative stay was significantly less than in Group II (12 +/- 2.03 days vs. 18 +/- 4.32 days; p = 0.001) Recurrent aspiration, respiratory tract infections, choking sensation and the need for tracheostomy were less frequent in Group I. The overall functional assessment was good in Group I. For treatment of pharyngo-esophageal obstruction, if antegrade dilatation is not possible due to technical reasons, retrograde dilatation is a viable option before opting for organ replacement/bypass procedures. There is no best replacement of the native organ to maintain quality of life.

Efficacy of commercial dressings in managing malodorous wounds

This paper investigates a novel in vitro method of ascertaining quantitative comparative data on a selection of commercial available odour absorbent wound dressing. The aim of this study is to determine and evaluate quantitative desirable data on the efficiency of odour absorbency along with other comparable physical characteristics of commercial odour absorbent dressings. This study is a part of an ongoing research programme into the design and development of novel odour absorbent dressings for managing malodorous wounds. The study also includes the development of a controlled in vitro test method that simulates a more realistic situation. A selection of commercially available activated charcoal dressings were analysed and tested, and comparative evaluation was carried out and discussed.

Venous leg ulcer treatment and practice--part 1: the causes and diagnosis of venous leg ulcers

This article, the first of a series of four on venous leg ulceration, discusses theories relating to the pathophysiology underlying the condition, and the range of diagnostic procedures undertaken to establish that ulceration is of venous origin.

Transabdominal modified devascularization procedure with or without esophageal stapler transection--an operation adequate for effective control of a variceal bleed. Is esophageal stapler transection necessary?

BACKGROUND

In Japan, the original Sugiura procedure reported favorable results in non-cirrhotic patients but in the West, the modified Sugiura procedure is not widely accepted because of high rebleeding, morbidity, and mortality in cirrhotics. We retrospectively analyzed the efficacy of our modified Sugiura procedure i.e., devascularization with/without esophageal transection combined with salvage endotherapy and pharmacotherapy for control of a variceal bleed.

MATERIALS AND METHODS

Between January 1999 and December 2004, 912 patients with variceal bleeding were treated. Of these, 66 (7.2%) patients were subjected to surgery after failed endotherapy/propranolol. Among these 66 patients, 52 had transabdominal devascularization (16 emergency, 36 elective); 14 patients underwent devascularization with esophageal stapler transection (group I), and 38 patients had devascularization without esophageal stapler transection (group II). Another 14 patients underwent elective end-to-side proximal splenorenal shunt surgery.

RESULTS

Postoperative mortality was 7.1% in group I, 10.5% in group II (P>0.05). Mortality for emergency surgery was 31.2% (5/16) but there were no deaths in the elective surgery group. Overall morbidity was 57.1% in group I and 21.0% in group II (P<0.05). The rates of variceal rebleeding were 7.1% and 7.8%; residual varices were 30.7% and 32.3%; recurrent varices were 7.6% and 5.8% following the group I and group II procedures, respectively, over a mean follow-up period of 39.9 (7-2) months. Esophageal transection-related morbidity (leak, stricture, and bleeding) was 21.4% (3/14) in group I.

CONCLUSIONS

Devascularization without esophageal stapler transection is a safe and effective procedure for adequate (urgent and long-term) control of variceal bleeding with similar results and less morbidity when compared to devascularization with esophageal transection in cirrhotic patients, as well as non-cirrhotic patients.
